22 <title>Applied Pokology: Array boundaries and closures in Poke</title> |

|
|
|
25 <description> Poke arrays are rather peculiar. One of their seemingly |
|
|
|
26 bizarre characteristics is the fact that the expressions |
|
|
|
27 calculating their boundaries (when they are bounded) evaluate |
|
|
|
28 in their own lexical environment, which is captured. In other |
|
|
|
29 words: the expressions denoting the boundaries of Poke arrays |
|
|
|
30 conform closures. Also, the way they evaluate may be |
|
|
|
31 surprising. This is no capricious. </description> |

91 [*] Use a .sig file to verify that the corresponding file (without the<br /> |

|
|
92 .sig suffix) is intact. First, be sure to download both the .sig file<br /> |
|
|
|
93 and the corresponding tarball. Then, run a command like this:<br /> |
|
|
|
94 <br /> |
|
|
|
95 gpg --verify gzip-1.11.tar.gz.sig<br /> |
|
|
|
96 <br /> |
|
|
|
97 If that command fails because you don't have the required public key,<br /> |
|
|
|
98 then run this command to import it:<br /> |
|
|
|
99 <br /> |
|
|
|
100 gpg --keyserver keys.gnupg.net --recv-keys 7FD9FCCB000BEEEE<br /> |

259 <h2>About GNU Parallel</h2> |
|
|
|
260 |
|
|
|
261 <p>GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel. |
|
|
|
262 <br /> |
|
|
|
263 </p> |
|
|
|
264 <p>If you use xargs and tee today you will find GNU Parallel very easy to use as GNU Parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU Parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU Parallel can even replace nested loops. |
|
|
|
265 <br /> |
|
|
|
266 </p> |
|
|
|
267 <p>GNU Parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU Parallel as input for other programs. |
|
|
|

270 <p>For example you can run this to convert all jpeg files into png and gif files and have a progress bar: |
|
|
|
271 <br /> |
|
|
|
272 </p> |
|
|
|
273 <p> parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif |
|
|
|
274 <br /> |
|
|
|
275 </p> |
|
|
|
276 <p>Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs: |
|
|
|
277 <br /> |
|
|
|
278 </p> |
|
|
|
279 <p> find . -name '*.jpg' | |
|
|
|
280 <br /> |
|
|
|
281 parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200 |

355 <h2>About GNU SQL</h2> |
|
|
|
356 |
|
|
|
357 <p>GNU sql aims to give a simple, unified interface for accessing databases through all the different databases' command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and port number), size (database and table size), and running queries. |
|
|
|
358 <br /> |
|
|
|
359 </p> |
|
|
|
360 <p>The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell. |

370 <h2>About GNU Niceload</h2> |
|
|
|
371 |
|
|
|
372 <p>GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.<br /> |

399 <description> <p>Yesterday, yet another devastating earthquake hit the southern area of Haiti. </p> |
|
|
|
400 |
|
|
|
401 |
|
|
|
402 |
|
|
|
403 <p>Immediately knowing about the earthquake, we contacted our representative in Haiti, <strong>Pierre Michel</strong> <strong>Augustin</strong>, and started an emergency humanitarian response in coordination with our team in the country . </p> |
|
|
|

|
406 |
|
|
|
407 <p>Haiti suffers from recurrent <strong>natural disasters</strong> (hurricanes, earthquakes). In the last years, Haiti has also been a victim of <strong>structural poverty and civil unrest.</strong> Haitians are strong, resilient, noble people. Haiti is the land of the free and the brave (see my post “<em><a href="https://meanmicio.org/2019/04/12/my-trip-to-haiti-the-land-of-the-free-and-the-brave/">My trip to Haiti, the land of the Free and the Brave</a></em>” ), yet it seems like the <strong>world has forgotten about Hait</strong>i.</p> |

|
|
|
419 <p>We need emergency response now, but we also need to work on Social Medicine, and tackle the socioeconomic determinants that are the root cause of the structural poverty in Haiti. Only then, our Haitians brothers and sisters will be able to recover the dignity that they deserve, and grow in prosperity. We need to create the conditions, working the local community in the country to strengthen the public health and education system. <a href="https://www.gnuhealth.org">GNU Health</a> is part of this program. </p> |
|
|
|
420 |
|
|
|
421 |
|
|
|
422 |
|
|
|
423 <p>Our local representative, engineer Pierre Michel Augustin, has been working in the localization of GNU Health, and by the end of 2021, we will have the GNU Health node fully operational in Limbé. The Haiti GNU Health office will provide training and support to the local and regional health professionals and institutions.</p> |

431 <p>Natural disasters have a profound impact in the short, medium and long period in any nation. The situation gets much worse when they hit impoverished nations. So, in the short term, we will put all the effort to tackle this emergency and save lives. For the medium and long term, we will continue the GNU Health node in Haiti and building the GNU Health Federation in the country, in cooperation with the local team, academic and health institutions. </p> |
|
|
|
432 |
|
|
|
433 |
|
|
|
434 |
|
|
|
435 <p>Creating local capacity is key to make the project sustainable. Resources will be dedicated to build the infrastructure (hardware, network..), but the main focus and effort will be on building local capacity, and training the local team to make them independent and build a sustainable and ethical model.</p> |

|
546 Use of the --unix-byte-offsets (-u) option now evokes a warning.<br /> |
|

547 Since 3.1, this Windows-only option has had no effect.<br /> |

|
551 Preprocessing N patterns would take at least O(N^2) time when too many<br /> |
|
|
|
552 patterns hashed to too few buckets. This now takes seconds, not days:<br /> |

|
|
553 : | grep -Ff &lt;(seq 6400000 | tr 0-9 A-J)<br /> |

560 <title>Parabola GNU/Linux-libre: TalkingParabola merged in main ISO and installation medium with installer</title> |
|
|

|
|
|
563 <description> <p>Last year <a href="https://www.archlinux.org/news/accessible-installation-medium/">Arch integrated the features from the TalkingArch project into archiso</a> and some months ago <a href="https://archlinux.org/news/installation-medium-with-installer/">they added an installer into their installation medium</a>. As a result, and with some delay, TalkingParabola was deprecated and we added these features to our ISOs too. They are available in out <a href="https://www.parabola.nu/download/">download page</a> as well.</p> |
|
|
|
564 <p>Note that although the OpenRC LXDE ISO has the speech boot option, this only works for CLI. Screen reader support will be added in the future for the GUI and the current installer will be replaced with one based in <a href="https://sourceforge.net/projects/revenge-installer/">Zen Installer</a>.</p> </description> |

569 <title>GNU Taler news: Code Blau GmbH deploys first external Taler auditor</title> |

573 We received a grant from NLnet foundation with the goal to qualify Code Blau GmbH to act as an external auditor for GNU Taler. To do this, we created a guide that describes how to deploy a Taler auditor and then practiced the steps using the existing Taler exchange deployment at BFH. Code Blau wrote a report detailing all the steps taken. Finally, we have created a draft of the kind of business agreement that Code Blau would enter with banks operating the Taler payment system. We thank CodeBlau for their work, and NLnet and the European Commission's Horizion 2020 NGI initiative for funding this work. |

583 <h1> |
|
|
|
584 GNUnet 0.15.0 released |
|
|
|
585 </h1> |
|
|
|
586 <p> |
|
|
|
587 We are pleased to announce the release of GNUnet 0.15.0. |
|
|
|
588 <br /> |
|
|
|
589 This is a new major release. It breaks protocol compatibility with the 0.14.x versions. |
|
|
|
590 Please be aware that Git master is thus henceforth |
|
|
|
591 <b> |
|
|
|
592 INCOMPATIBLE |
|
|
|
593 </b> |
|
|
|
594 with |
|
|
|
595 the 0.14.x GNUnet network, and interactions between old and new peers |
|
|
|
596 will result in issues. 0.14.x peers will be able to communicate with Git |
|
|
|
597 master or 0.14.x peers, but some services - in particular GNS - will not be compatible. |
|
|
|
598 <br /> |
|
|
|
599 The MESSENGER service goes out of experimental to be used by |
|
|
|
600 libraries and applications as dependency. It handles decentralized |
|
|
|
601 messaging in flexible groups by using the CADET service and messages |
|
|
|
602 can be signed with your ego from the IDENTITY service. The service |
|
|
|
603 is still in an early stage, so its protocol (currently version 0.1) |
|
|
|
604 will likely adapt or change in future releases to some degree. |
|
|
|
605 <br /> |
|
|
|
606 In terms of usability, users should be aware that there are still |
|
|
|
607 <b> |
|
|
|
608 a number of known open issues |
|
|
|
609 </b> |
|
|
|
610 in particular with respect to ease |
|
|
|
611 of use, but also some critical privacy issues especially for mobile users. |
|
|
|
612 Also, the nascent network is tiny and thus unlikely to |
|
|
|
613 provide good anonymity or extensive amounts of interesting information. |
|
|
|
614 As a result, the 0.15.0 release is still |
|
|
|
615 <b> |
|
|
|
616 only suitable for early adopters |
|
|
|
617 with some reasonable pain tolerance |
|
|
|
618 </b> |

844 <description> <p>It was one of these days where some of us on IRC were rehashing that old |
|
|
|
845 problem—that application startup in Guix causes a |
|
|
|
846 “<a href="https://linux.die.net/man/2/stat"><code>stat</code></a> storm”—and lamenting the |
|
|
|
847 lack of a solution when suddenly, Ricardo |
|
|
|
848 <a href="https://logs.guix.gnu.org/guix/2020-11-24.log#183934">proposes</a> what, |
|
|
|
849 in hindsight, looks like an obvious solution: “maybe we could use a |
|
|
|
850 per-application ld cache?”. A moment where collective thinking exceeds |
|
|
|
851 the sum of our individual thoughts. The result is one of the many |
|
|
|
852 features that made it in the <code>core-updates</code> branch, slated to be merged |
|
|
|
853 in the coming weeks, one that reduces application startup time.</p><h1>ELF files and their dependencies</h1><p>Before going into detail, let’s look at what those “<code>stat</code> storms” look |
|
|
|
854 like and where they come from. Loading an |
|
|
|
855 <a href="https://en.wikipedia.org/wiki/Executable_and_Linkable_Format">ELF</a> |
|
|
|
856 executable involves loading the shared libraries (the <code>.so</code> files, for |
|
|
|
857 “shared objects”) it depends on, recursively. This is the job of the |
|
|
|
858 <em>loader</em> (or <em>dynamic linker</em>), <code>ld.so</code>, which is part of the GNU C |
|
|
|
859 Library (glibc) package. What shared libraries an executable like that |
|
|
|
860 of Emacs depends on? The <code>ldd</code> command answers that question:</p><pre><code>$ ldd $(type -P .emacs-27.2-real) |

|
|
|
869 $ ldd $(type -P .emacs-27.2-real) | wc -l |
|
|
|
870 89</code></pre><p>(If you’re wondering why we’re looking at <code>.emacs-27.2-real</code> rather than |
|
|
|
871 <code>emacs-27.2</code>, it’s because in Guix the latter is a tiny shell wrapper |
|
|
|
872 around the former.)</p><p>To load a graphical program like Emacs, the loader needs to load more |
|
|
|
873 than 80 shared libraries! Each is in its own <code>/gnu/store</code> sub-directory |
|
|
|
874 in Guix, one directory per package.</p><p>But how does <code>ld.so</code> know where to find these libraries in the first |
|
|
|
875 place? In Guix, during the link phase that produces an ELF file |
|
|
|
876 (executable or shared library), we tell the |
|
|
|
877 <a href="https://en.wikipedia.org/wiki/Linker_%28computing%29">linker</a> to |
|
|
|
878 populate the <code>RUNPATH</code> entry of the ELF file with the list of |
|
|
|
879 directories where its dependencies may be found. This is done by |
|
|
|
880 passing |
|
|
|
881 <a href="https://sourceware.org/binutils/docs/ld/Options.html#index-_002drpath_003ddir"><code>-rpath</code></a> |
|
|
|
882 options to the linker, which Guix’s <a href="https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/ld-wrapper.in">“linker |
|
|
|
883 wrapper”</a> |
|
|
|
884 takes care of. The <code>RUNPATH</code> is the <em>run-time library search path</em>: |
|
|
|
885 it’s a colon-separated list of directories where <code>ld.so</code> will look for |
|
|
|
886 shared libraries when it loads an ELF file. We can look at the |
|
|
|
887 <code>RUNPATH</code> of our Emacs executable like this:</p><pre><code>$ objdump -x $(type -P .emacs-27.2-real) | grep RUNPATH |
|
|
|
888 RUNPATH /gnu/store/fa6wj5bxkj5ll1d7292a70knmyl7a0cr-glibc-2.31/lib:/gnu/store/01b4w3m6mp55y531kyi1g8shh722kwqm-gcc-7.5.0-lib/lib:/gnu/store/l1wwr5c34593gqxvp34qbwdkaf7xhdbd-libtiff-4.2.0/lib:/gnu/store/5khkwz9g6vza1n4z8xlmdrwhazz7m8wp-libjpeg-turbo-2.0.5/lib:[…]</code></pre><p>This <code>RUNPATH</code> has 39 entries, which roughly corresponds to the number |
|
|
|
889 of direct dependencies of the executable—dependencies are listed as |
|
|
|
890 <code>NEEDED</code> entries in the ELF file:</p><pre><code>$ objdump -x $(type -P .emacs-27.2-real) | grep NEED | head |
|
|
|
891 NEEDED libtiff.so.5 |
|
|
|
892 NEEDED libjpeg.so.62 |

893 NEEDED libpng16.so.16 |
|

894 NEEDED libz.so.1 |
|

895 NEEDED libgif.so.7 |
|
|

896 NEEDED libXpm.so.4 |
|
|

|
|
|
901 $ objdump -x $(type -P .emacs-27.2-real) | grep NEED | wc -l |
|
|
|
902 52</code></pre><p>(Some of these <code>.so</code> files live in the same directory, which is why |
|
|
|
903 there are more <code>NEEDED</code> entries than directories in the <code>RUNPATH</code>.)</p><p>A system such as Debian that follows the <a href="https://en.wikipedia.org/wiki/Filesystem_Hierarchy_Standard">file system hierarchy |
|
|
|
904 standard</a> |
|
|
|
905 (FHS), where all libraries are in <code>/lib</code> or <code>/usr/lib</code>, does not have to |
|
|
|
906 bother with <code>RUNPATH</code>: all <code>.so</code> files are known to be found in one of |
|
|
|
907 these two “standard” locations. Anyway, let’s get back to our initial |
|
|
|
908 topic: the “<code>stat</code> storm”.</p><h1>Walking search paths</h1><p>As you can guess, when we run Emacs, the loader first needs to locate |
|
|
|
909 and load the 80+ shared libraries it depends on. That’s where things |
|
|
|
910 get pretty inefficient: the loader will search each <code>.so</code> file Emacs |
|
|
|
911 depends on in one of the 39 directories listed in its <code>RUNPATH</code>. |
|
|
|
912 Likewise, when it finally finds <code>libgtk-3.so</code>, it’ll look for its |
|
|
|
913 dependencies in each of the directories in its <code>RUNPATH</code>. We can see |
|
|
|
914 that at play by tracing system calls with the |
|
|
|
915 <a href="https://strace.io/"><code>strace</code></a> command:</p><pre><code>$ strace -c emacs --version |

961 […]</code></pre><p>Above is the sequence where we see <code>ld.so</code> look for <code>libpng16.so.16</code>, |
|
|
|
962 searching in locations where we <em>know</em> it’s not going to find it. A bit |
|
|
|
963 ridiculous. How does this affect performance? The impact is small in |
|
|
|
964 the most favorable case—on a hot cache, with fast solid state device |
|
|
|
965 (SSD) storage. But it likely has a visible effect in other cases—on a |
|
|
|
966 cold cache, with a slower spinning hard disk drive (HDD), on a network |
|
|
|
967 file system (NFS).</p><h1>Enter the per-package loader cache</h1><p>The idea that Ricardo submitted, using a loader cache, makes a lot of |
|
|
|
968 sense: we know from the start that <code>libpng.so</code> may only be found in |
|
|
|
969 <code>/gnu/store/…-libpng-1.6.37</code>, no need to look elsewhere. In fact, it’s |
|
|
|
970 not new: glibc has had such a cache “forever”; it’s the |
|
|
|
971 <code>/etc/ld.so.cache</code> file you can see on FHS distros and which is |
|
|
|
972 typically created by running |
|
|
|
973 <a href="https://linux.die.net/man/8/ldconfig"><code>ldconfig</code></a> when a package has |
|
|
|
974 been installed. Roughly, the cache maps library <code>SONAME</code>s, such as |
|
|
|
975 <code>libpng16.so.16</code>, to their file name on disk, say |
|
|
|
976 <code>/usr/lib/libpng16.so.16</code>.</p><p>The problem is that this cache is inherently system-wide: it assumes |
|
|
|
977 that there is only <em>one</em> <code>libpng16.so</code> on the system; any binary that |
|
|
|
978 depends on <code>libpng16.so</code> will load it from its one and only location. |
|
|
|
979 This models perfectly matches the FHS, but it’s at odds with the |
|
|
|
980 flexibility offered by Guix, where several variants or versions of the |
|
|
|
981 library can coexist on the system, used by different applications. |
|
|
|
982 That’s the reason why Guix and other non-FHS distros such as NixOS or |
|
|
|
983 GoboLinux typically <a href="https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/base.scm?id=a92dfbce30777de6ca05031e275410cf9f56c84c#n716">turn |
|
|
|
984 off</a> |
|
|
|
985 that feature altogether… and pay the cost of those <code>stat</code> storms.</p><p>The insight we gained on that Tuesday evening IRC conversation is that |
|
|
|
986 we could <em>adapt</em> glibc’s loader cache to our setting: instead of a |
|
|
|
987 system-wide cache, we’d have a <em>per-application loader cache</em>. As one |
|
|
|
988 of the last package <a href="https://guix.gnu.org/manual/en/html_node/Build-Phases.html">build |
|
|
|
989 phases</a>, |
|
|
|
990 we’d run <code>ldconfig</code> to create <code>etc/ld.so.cache</code> within that package’s |
|
|
|
991 <code>/gnu/store</code> sub-directory. We then need to modify the loader so it |
|
|
|
992 would look for <code>${ORIGIN}/../etc/ld.so.cache</code> instead of |
|
|
|
993 <code>/etc/ld.so.cache</code>, where <code>${ORIGIN}</code> is the location of the ELF file |
|
|
|
994 being loaded. A discussion of these changes is <a href="https://issues.guix.gnu.org/44899">in the issue |
|
|
|
995 tracker</a>; you can see <a href="https://git.savannah.gnu.org/cgit/guix.git/tree/gnu/packages/patches/glibc-dl-cache.patch?h=core-updates&amp;id=0236013cd0fc86ff4a042885c735e3f36a7f5c25">the glibc |

|
|
|
998 phase</a>. |
|
|
|
999 In short, the <code>make-dynamic-linker-cache</code> phase computes the set of |
|
|
|
1000 direct and indirect dependencies of an ELF file using the |
|
|
|
1001 <a href="https://git.savannah.gnu.org/cgit/guix.git/tree/guix/build/gremlin.scm?id=0236013cd0fc86ff4a042885c735e3f36a7f5c25#n265"><code>file-needed/recursive</code></a> |
|
|
|
1002 procedure and derives from that the library search path, creates a |
|
|
|
1003 temporary <code>ld.so.conf</code> file containing this search path for use by |
|
|
|
1004 <code>ldconfig</code>, and finally runs <code>ldconfig</code> to actually build the cache.</p><p>How does this play out in practice? Let’s try an <code>emacs</code> build that |
|
|
|
1005 uses this new loader cache:</p><pre><code>$ strace -c /gnu/store/ijgcbf790z4x2mkjx2ha893hhmqrj29j-emacs-27.2/bin/emacs --version |

1023 100.00 0.010144 8 1128 24 total</code></pre><p>Compared to what we have above, the total number of system calls has |
|
|
|
1024 been divided by 3, and the fraction of erroneous system calls goes from |
|
|
|
1025 67% to 0.2%. Quite a difference! We count on you, dear users, to <a href="https://guix.gnu.org/en/contact">let |
|
|
|
1026 us know</a> how this impacts load time for |
|
|
|
1027 you.</p><h1>Flexibility without <code>stat</code> storms</h1><p>With <a href="https://www.gnu.org/software/stow">GNU Stow</a> in the 1990s, and |
|
|
|
1028 then Nix, Guix, and other distros, the benefits of flexible file layouts |
|
|
|
1029 rather than the rigid Unix-inherited FHS have been demonstrated—nowadays |
|
|
|
1030 I see it as an antidote to opaque and bloated application bundles à la |
|
|
|
1031 Docker. Luckily, few of our system tools have FHS assumptions baked in, |
|
|
|
1032 probably in large part thanks to GNU’s insistence on a <a href="https://www.gnu.org/prep/standards/html_node/Directory-Variables.html">rigorous |
|
|
|
1033 installation directory |
|
|
|
1034 categorization</a> |
|
|
|
1035 in the early days rather than hard-coded directory names. The loader |
|
|
|
1036 cache is one of the few exceptions. Adapting it to a non-FHS context is |
|
|
|
1037 fruitful for Guix and for the other distros and packaging tools in a |
|
|
|
1038 similar situation; perhaps it could become an option in glibc proper?</p><p>This is not the end of <code>stat</code> storms, though. Interpreters and language |
|
|
|
1039 run-time systems rely on search paths—<code>GUILE_LOAD_PATH</code> for Guile, |
|
|
|
1040 <code>PYTHONPATH</code> for Python, <code>OCAMLPATH</code> for OCaml, etc.—and are equally |
|
|
|
1041 prone to stormy application startups. Unlike ELF, they do not have a |
|
|
|
1042 mechanism akin to <code>RUNPATH</code>, let alone a run-time search path cache. We |
|
|
|
1043 have yet to find ways to address these.</p><h4>About GNU Guix</h4><p><a href="https://guix.gnu.org">GNU Guix</a> is a transactional package manager and |
|
|
|
1044 an advanced distribution of the GNU system that <a href="https://www.gnu.org/distros/free-system-distribution-guidelines.html">respects user |
|
|
|
1045 freedom</a>. |
|
|
|
1046 Guix can be used on top of any system running the Hurd or the Linux |
|
|
|
1047 kernel, or it can be used as a standalone operating system distribution |
|
|
|
1048 for i686, x86_64, ARMv7, AArch64 and POWER9 machines.</p><p>In addition to standard package management features, Guix supports |
|
|
|
1049 transactional upgrades and roll-backs, unprivileged package management, |
|
|
|
1050 per-user profiles, and garbage collection. When used as a standalone |
|
|
|
1051 GNU/Linux distribution, Guix offers a declarative, stateless approach to |
|
|
|
1052 operating system configuration management. Guix is highly customizable |
|

1066 <br /> |
|
|
|
1067 </p> |
|
|
|
1068 <p>The GNU C Library version 2.34 is now available. |
|
|
|
1069 <br /> |
|
|
|
1070 </p> |
|
|
|
1071 <p>The GNU C Library is used as <strong>the</strong> C library in the GNU system and |
|
|
|
1072 <br /> |
|
|
|
1073 in GNU/Linux systems, as well as many other systems that use Linux |
|
|
|
1074 <br /> |
|
|
|
1075 as the kernel. |
|
|
|
1076 <br /> |
|
|
|
1077 </p> |
|
|
|
1078 <p>The GNU C Library is primarily designed to be a portable |
|
|
|
1079 <br /> |
|
|
|
1080 and high performance C library. It follows all relevant |
|
|
|
1081 <br /> |
|
|
|
1082 standards including ISO C11 and POSIX.1-2017. It is also |
|
|
|
1083 <br /> |
|
|
|
1084 internationalized and has one of the most complete |
|
|
|
1085 <br /> |
|
|
|
1086 internationalization interfaces known. |

1102 <p>NEWS for version 2.34 |
|
|
|
1103 <br /> |
|
|
|
1104 ===================== |
|
|
|
1105 <br /> |
|
|
|
1106 </p> |
|
|
|
1107 <p>Major new features: |
|
|
|
1108 <br /> |
|
|
|
1109 </p> |
|
|
|
1110 <ul> |
|
|
|
1111 <li>In order to support smoother in-place-upgrades and to simplify |
|
|
|
1112 </li> |
|
|
|
1113 </ul><p> the implementation of the runtime all functionality formerly |
|
|
|
1114 <br /> |
|
|
|
1115 implemented in the libraries libpthread, libdl, libutil, libanl has |
|
|
|
1116 <br /> |
|
|
|
1117 been integrated into libc. New applications do not need to link with |
|
|
|
1118 <br /> |
|
|
|
1119 -lpthread, -ldl, -lutil, -lanl anymore. For backwards compatibility, |
|
|
|
1120 <br /> |
|
|
|
1121 empty static archives libpthread.a, libdl.a, libutil.a, libanl.a are |
|
|
|
1122 <br /> |
|
|
|
1123 provided, so that the linker options keep working. Applications which |
|
|
|
1124 <br /> |
|
|
|
1125 have been linked against glibc 2.33 or earlier continue to load the |
|
|
|
1126 <br /> |
|
|
|
1127 corresponding shared objects (which are now empty). The integration |
|
|
|
1128 <br /> |
|
|
|
1129 of those libraries into libc means that additional symbols become |
|
|
|
1130 <br /> |
|
|
|
1131 available by default. This can cause applications that contain weak |
|
|
|
1132 <br /> |
|
|
|
1133 references to take unexpected code paths that would only have been |
|
|
|
1134 <br /> |
|
|
|
1135 used in previous glibc versions when e.g. preloading libpthread.so.0, |
|
|
|
1136 <br /> |
|
|
|
1137 potentially exposing application bugs. |
|
|
|
1138 <br /> |
|
|
|
1139 </p> |
|
|
|
1140 <ul> |
|
|
|
1141 <li>When _DYNAMIC_STACK_SIZE_SOURCE or _GNU_SOURCE are defined, |
|
|
|
1142 </li> |
|
|
|
1143 </ul><p> PTHREAD_STACK_MIN is no longer constant and is redefined to |
|
|
|
1144 <br /> |
|
|
|
1145 sysconf(_SC_THREAD_STACK_MIN). This supports dynamic sized register |
|
|
|
1146 <br /> |
|
|
|
1147 sets for modern architectural features like Arm SVE. |
|
|
|
1148 <br /> |
|
|
|
1149 </p> |
|
|
|
1150 <ul> |
|
|
|
1151 <li>Add _SC_MINSIGSTKSZ and _SC_SIGSTKSZ. When _DYNAMIC_STACK_SIZE_SOURCE |
|
|
|
1152 </li> |
|
|
|
1153 </ul><p> or _GNU_SOURCE are defined, MINSIGSTKSZ and SIGSTKSZ are no longer |
|
|
|
1154 <br /> |
|
|
|
1155 constant on Linux. MINSIGSTKSZ is redefined to sysconf(_SC_MINSIGSTKSZ) |
|
|
|
1156 <br /> |
|
|
|
1157 and SIGSTKSZ is redefined to sysconf (_SC_SIGSTKSZ). This supports |
|
|
|
1158 <br /> |
|
|
|
1159 dynamic sized register sets for modern architectural features like |
|
|
|
1160 <br /> |
|
|
|
1161 Arm SVE. |
|
|
|
1162 <br /> |
|
|
|
1163 </p> |
|
|
|
1164 <ul> |
|
|
|
1165 <li>The dynamic linker implements the --list-diagnostics option, printing |
|
|
|
1166 </li> |
|
|
|
1167 </ul><p> a dump of information related to IFUNC resolver operation and |
|
|
|
1168 <br /> |
|
|
|
1169 glibc-hwcaps subdirectory selection. |
|
|
|
1170 <br /> |
|
|
|
1171 </p> |
|
|
|
1172 <ul> |
|
|
|
1173 <li>On Linux, the function execveat has been added. It operates similar to |
|
|
|
1174 </li> |
|
|
|
1175 </ul><p> execve and it is is already used to implement fexecve without requiring |
|
|
|
1176 <br /> |
|
|
|
1177 /proc to be mounted. However, different than fexecve, if the syscall is not |
|
|
|
1178 <br /> |
|
|
|
1179 supported by the kernel an error is returned instead of trying a fallback. |
|
|
|
1180 <br /> |
|
|
|
1181 </p> |
|
|
|
1182 <ul> |
|
|
|
1183 <li>The ISO C2X function timespec_getres has been added. |
|
|
|
1184 </li> |
|
|
|
1185 </ul> |
|
|
|
1186 <ul> |
|
|
|
1187 <li>The feature test macro <em>_STDC_WANT_IEC_60559_EXT_</em>, from draft ISO |
|
|
|
1188 </li> |
|
|
|
1189 </ul><p> C2X, is supported to enable declarations of functions defined in Annex F |
|
|
|
1190 <br /> |
|
|
|
1191 of C2X. Those declarations are also enabled when |
|
|
|
1192 <br /> |
|
|
|
1193 <em>_STDC_WANT_IEC_60559_BFP_EXT_</em>, as specified in TS 18661-1, is |
|
|
|
1194 <br /> |
|
|
|
1195 defined, and when _GNU_SOURCE is defined. |
|
|
|
1196 <br /> |
|
|
|
1197 </p> |
|
|
|
1198 <ul> |
|
|
|
1199 <li>On powerpc64*, glibc can now be compiled without scv support using the |
|
|
|
1200 </li> |
|
|
|
1201 </ul><p> --disable-scv configure option. |
|
|
|
1202 <br /> |
|
|
|
1203 </p> |
|
|
|
1204 <ul> |
|
|
|
1205 <li>Add support for 64-bit time_t on configurations like x86 where time_t |
|
|
|
1206 </li> |
|
|
|
1207 </ul><p> is traditionally 32-bit. Although time_t still defaults to 32-bit on |
|
|
|
1208 <br /> |
|
|
|
1209 these configurations, this default may change in future versions. |
|
|
|
1210 <br /> |
|
|
|
1211 This is enabled with the _TIME_BITS preprocessor macro set to 64 and is |
|
|
|
1212 <br /> |
|
|
|
1213 only supported when LFS (_FILE_OFFSET_BITS=64) is also enabled. It is |
|
|
|
1214 <br /> |
|
|
|
1215 only enabled for Linux and the full support requires a minimum kernel |
|
|
|
1216 <br /> |
|
|
|
1217 version of 5.1. |
|
|
|
1218 <br /> |
|
|
|
1219 </p> |
|
|
|
1220 <ul> |
|
|
|
1221 <li>The main gconv-modules file in glibc now contains only a small set of |
|
|
|
1222 </li> |
|
|
|
1223 </ul><p> essential converter modules and the rest have been moved into a supplementary |
|
|
|
1224 <br /> |
|
|
|
1225 configuration file gconv-modules-extra.conf in the gconv-modules.d directory |
|
|
|
1226 <br /> |
|
|
|
1227 in the same GCONV_PATH. Similarly, external converter modules directories |
|
|
|
1228 <br /> |
|
|
|
1229 may have supplementary configuration files in a gconv-modules.d directory |
|
|
|
1230 <br /> |
|
|
|
1231 with names ending with .conf to logically classify the converter modules in |
|
|
|
1232 <br /> |
|
|
|
1233 that directory. |
|
|
|
1234 <br /> |
|
|
|
1235 </p> |
|
|
|
1236 <ul> |
|
|
|
1237 <li>On Linux, a new tunable, glibc.pthread.stack_cache_size, can be used |
|
|
|
1238 </li> |
|
|
|
1239 </ul><p> to configure the size of the thread stack cache. |
|
|
|
1240 <br /> |
|
|
|
1241 </p> |
|
|
|
1242 <ul> |
|
|
|
1243 <li>The function _Fork has been added as an async-signal-safe fork replacement |
|
|
|
1244 </li> |
|
|
|
1245 </ul><p> since Austin Group issue 62 droped the async-signal-safe requirement for |
|
|
|
1246 <br /> |
|
|
|
1247 fork (and it will be included in the future POSIX standard). The new _Fork |
|
|
|
1248 <br /> |
|
|
|
1249 function does not run any atfork function neither resets any internal state |
|
|
|
1250 <br /> |
|
|
|
1251 or lock (such as the malloc one), and only sets up a minimal state required |
|
|
|
1252 <br /> |
|
|
|
1253 to call async-signal-safe functions (such as raise or execve). This function |
|
|
|
1254 <br /> |
|
|
|
1255 is currently a GNU extension. |
|
|
|
1256 <br /> |
|
|
|
1257 </p> |
|
|
|
1258 <ul> |
|
|
|
1259 <li>On Linux, the close_range function has been added. It allows efficiently |
|
|
|
1260 </li> |
|
|
|
1261 </ul><p> closing a range of file descriptors on recent kernels (version 5.9). |
|
|
|
1262 <br /> |
|
|
|
1263 </p> |
|
|
|
1264 <ul> |
|
|
|
1265 <li>The function closefrom has been added. It closes all file descriptors |
|
|
|
1266 </li> |
|
|
|
1267 </ul><p> greater than or equal to a given integer. This function is a GNU extension, |
|
|
|
1268 <br /> |
|
|
|
1269 although it is also present in other systems. |
|
|
|
1270 <br /> |
|
|
|
1271 </p> |
|
|
|
1272 <ul> |
|
|
|
1273 <li>The posix_spawn_file_actions_addclosefrom_np function has been added, |
|
|
|
1274 </li> |
|
|
|
1275 </ul><p> enabling posix_spawn and posix_spawnp to close all file descriptors greater |
|
|
|
1276 <br /> |
|
|
|
1277 than or equal to a given integer. This function is a GNU extension, |
|
|
|
1278 <br /> |
|
|
|
1279 although Solaris also provides a similar function. |
|
|

1996 diff no longer treats a closed stdin as representing an absent file<br /> |

2004 <br /> |
|
|
|
2005 diff and related programs no longer get confused if stdin, stdout,<br /> |
|
|
|
2006 or stderr are closed. Previously, they sometimes opened files into<br /> |
|

|
2007 file descriptors 0, 1, or 2 and then mistakenly did I/O with them<br /> |

2008 that was intended for stdin, stdout, or stderr.<br /> |

2009 [bug#33965 present since "the beginning"]<br /> |
|
|
|
2010 <br /> |
|

2011 cmp, diff and sdiff no longer treat negative command-line<br /> |

|
|
2012 option-arguments as if they were large positive numbers.<br /> |

|
2088 </p> |
|
|
|
2089 <p>It does not have to be as detailed as Juan's. It is perfectly fine if you just say your name, and what field you are using GNU Parallel for. |

2137 <h2>About GNU Parallel</h2> |
|
|
|
2138 |
|
|
|
2139 <p>GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel. |
|
|
|
2140 <br /> |
|
|
|
2141 </p> |
|
|
|
2142 <p>If you use xargs and tee today you will find GNU Parallel very easy to use as GNU Parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU Parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU Parallel can even replace nested loops. |
|
|
|
2143 <br /> |
|
|
|
2144 </p> |
|
|
|
2145 <p>GNU Parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU Parallel as input for other programs. |
|
|
|
2146 <br /> |
|
|
|
2147 </p> |
|
|
|
2148 <p>For example you can run this to convert all jpeg files into png and gif files and have a progress bar: |
|
|
|
2149 <br /> |
|
|
|
2150 </p> |
|
|
|
2151 <p> parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif |
|
|
|
2152 <br /> |
|
|
|
2153 </p> |
|
|
|
2154 <p>Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs: |
|
|
|
2155 <br /> |
|
|
|
2156 </p> |
|
|
|
2157 <p> find . -name '*.jpg' | |
|
|
|
2158 <br /> |
|
|
|
2159 parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200 |
|

2233 <h2>About GNU SQL</h2> |
|
|
|
2234 |
|
|
|
2235 <p>GNU sql aims to give a simple, unified interface for accessing databases through all the different databases' command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and port number), size (database and table size), and running queries. |
|
|
|
2236 <br /> |
|
|
|
2237 </p> |
|
|
|
2238 <p>The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell. |
|
|
|
2239 <br /> |
|
|
|
2240 </p> |

2248 <h2>About GNU Niceload</h2> |
|
|
|
2249 |
|
|
|
2250 <p>GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.<br /> |

2279 <description> <p class="has-drop-cap">Leonardo da Vinci said “<em>simplicity is the ultimate sophistication</em>“, but it seems like the “modern” computing world never heard that quote, or ignore it. Today, a single application takes hundreds of megabytes, both of disk and RAM space. Slow, buggy, inefficient systems at every level. </p> |
|
|
|
2280 |
|
|
|
2281 |
|
|
|
2282 |
|
|
|
2283 <p>Probably the best example on this cluttering mess comes from the mobile computing. Most phones are bloated with useless software that not only hinders the navigation experience, but pose a threat to your privacy. Yes, all this software is proprietary. Worst of it, you can not even uninstall it.</p> |
|
|
|
2284 |
|
|
|
2285 |
|
|
|
2286 |
|
|
|
2287 <p>Fortunately, there is hope. Let me introduce <strong>SXMO, the Simple X on Mobile </strong>project. As the authors describe it, SXMO is a minimalist environment for Linux smartphones, such as the <strong>PinePhone</strong>. SXMO embraces simplicity, and simplicity is both elegant and efficient. </p> |

2307 <p>SXMO uses a tiling window manager called <strong>dwm</strong> (Dynamic Window Manager), which allocates the different applications in the most efficient way. The dwm project is available as a single binary file, which source is intended not to exceed 2000 lines of code. That is amazing.</p> |
|
|
|
2308 |
|
|
|
2309 |
|
|
|
2310 |
|
|
|
2311 <p>Simplicity is robust, and that again applies to SXMO. All the necessary components expected on a mobile phone (making and receiving calls, browsing the Internet, SMS messaging,..) just work. Moreover, SMXO comes with a scripting system that allow us to write solutions to our needs. For instance, the screenshots you see were taken with a script of 3 lines of code. Just place the little program under your “<em>userscripts</em>” directory, and <em>voilà </em>!, you’re ready to make screenshots from your PinePhone!</p> |

2453 <title>Parabola GNU/Linux-libre: [From Arch] Sorting out old password hashes</title> |

|
|
|
2456 <description> <p>Starting with <code>libxcrypt</code> 4.4.21, weak password hashes (such as <em>MD5</em> and <em>SHA1</em>) are no longer accepted for new passwords. Users that still have their passwords stored with a weak hash will be asked to update their password on their next login.</p> |
|
|
|
2457 <p>If the login just fails (for example from display manager) switch to a virtual terminal (<em>Ctrl-Alt-F2</em>) and log in there once.</p> </description> |

|
2507 <description> <p><img alt="A picture of Chris and Morgan together" src="https://dustycloud.org/gfx/goodies/chris-and-morgan-2021-06-27.jpg" /></p> |
|
|
|
2508 <p>I recently came out as nonbinary trans-femme. |
|
|
|
2509 That's a picture of me on the left, with my spouse Morgan Lemmer-Webber |
|
|
|
2510 on the right.</p> |
|
|
|
2511 <p>In a sense, not much has changed, and so much has changed. |
|
|
|
2512 I've dropped the "-topher" from my name, and given the common tendency |
|
|
|
2513 to apply gender to pronouns in English, please either use nonbinary |
|
|
|
2514 pronouns or feminine pronouns to apply to me. |
|
|
|
2515 Other changes are happening as I wander through this space, from |
|
|
|
2516 appearance to other things. |
|
|
|
2517 (Probably the biggest change is finally achieving something resembling |
|
|
|
2518 self-acceptance, however.)</p> |
|
|
|
2519 <p>If you want to know more, |
|
|
|
2520 <a href="https://fossandcrafts.org/episodes/30-gender-sexuality-personal-perspective.html">Morgan and I did a podcast episode</a> |
|
|
|
2521 which explains more from my present standing, and also explains Morgan's |
|
|
|
2522 experiences with being demisexual, which not many people know about! |
|
|
|
2523 (Morgan has been incredible through this whole process, by the way.)</p> |
|
|
|
2524 <p>But things may change further. |
|
|
|
2525 Maybe a year from now those changes may be even more drastic, or maybe |
|
|
|
2526 not. |
|
|
|
2527 We'll see. |
|
|
|
2528 I am wandering, and I don't know where I will land, but it won't be |
|
|
|
2529 back to where I was.</p> |
|
|
|
2530 <p>At any rate, I've spent much of my life not being able to stand myself |
|
|
|
2531 for how I look and feel. |
|
|
|
2532 For most of my life, I have not been able to look at myself in a mirror |
|
|
|
2533 for more than a second or two due to the revulsion I felt at the person |
|
|
|
2534 I saw staring back at me. |
|
|
|
2535 The last few weeks have been a shift change for me in that regard... |
|
|
|
2536 it's a very new experience to feel so happy with myself.</p> |
|
|
|
2537 <p>I'm only at the beginning of this journey. |
|
|
|
2538 I'd appreciate your support... people have been incredibly kind to me |
|
|
|
2539 by and large so far but like everyone who goes through a process like this, |
|
|
|
2540 it's very hard in those experiences where people aren't. |
|
|
|
2541 Thank you to everyone who has been there for me so far.</p> </description> |

2556 <p><strong>MyGNUHealth</strong> 1.0 us out! The GNU Health Libre Personal Health Record is now ready for prime time! |
|
|
|
2557 <br /> |
|
|
|
2558 </p> |
|
|
|
2559 <p>This is great news. Great news because citizens around the world have now access to a Free/Libre application, focused on privacy, that puts them in control of their health. |
|
|
|
2560 <br /> |
|
|
|
2561 </p> |
|
|
|
2562 <p>Health is personal, so is the health data. It’s been years since I got the idea of expanding the GNU Health ecosystem, not only to the health professionals and institutions, but making it personal, accessible to individuals. Now is a reality! |
|
|
|
2563 <br /> |
|
|
|
2564 </p> |
|
|
|
2565 <p>Throughout these years, the mobile health (mHealth) has been governed by private companies that benefit from your health data. Private companies, private insurances, proprietary operating systems, proprietary health applications. Big business, no privacy. |
|
|
|
2566 <br /> |
|
|
|
2567 </p> |
|
|
|
2568 <p>The GNU Health ecosystem exists because of Free software. Thanks to communities such as GNU and KDE, we can have fully operational operating systems, desktop environments, databases and programming languages that allow us to use and write free software. GNU Health is one example. |
|
|
|
2569 <br /> |
|
|
|
2570 </p> |
|
|
|
2571 <p>The Libre Software movement fights for the advancement of our societies, by providing universality in computing. In the case of GNU Health, that freedom and equity in computing is applied into the healthcare and social medicine domains. Health is a non-negotiable human right, so it must be health informatics. |
|
|

|
|
|
2574 <h3>What is MyGNUHealth?</h3> |
|
|
|
2575 |
|
|
|
2576 <p>MyGNUHealth (MyGH)is a Health Personal Record application focused in <strong>privacy</strong>, that can be used in desktops and mobile devices. |
|
|
|
2577 <br /> |
|
|
|
2578 </p> |
|
|
|
2579 <p>MyGH embraces the main health domains (*bio-psycho-social*). All the components in the GNU Health ecosystem combine social medicine and primary care with the latest on bioinformatics and precision medicine. The complex interactions between these health domains play a key role in the state of health and disease of an individual, family and society. |
|
|
|
2580 <br /> |
|
|
|
2581 </p> |
|
|
|
2582 <p>MyGH has the functionality of a health and activity tracker, and that of a health diary / record. It records and tracks the main anthropometric and physiological measures, such as weight, blood pressure, blood sugar level or oxygen saturation. It keeps track of your lifestyle, nutrition, physical activity, and sleep, with numerous charts to visualize the trends. |
|
|
|
2583 <br /> |
|
|
|
2584 </p> |
|
|
|
2585 <p>MyGNUHealth is also a diary, that records all relevant information from the medical and social domain and their context. In the medical domain, you can record your encounters, immunizations, hospitalizations, lab tests,genetic and family history, among others. In the genetic context, MyGH provides a dataset of over 30000 natural variants / SNP from <strong>UniProt</strong> that are relevant in human. Entering the RefSNP will automatically provide the information about that particular variant and it clinical significance. |
|
|
|
2586 <br /> |
|
|
|
2587 </p> |
|
|
|
2588 <p>The Social domain, contains the key social determinants of health (Social Gradient, Early life development, Stress, Social exclusion, Working conditions, Education, Physical environment, Unemployment, Social Support, Addiction, Food, Transportation, Health services, Family functionality, Family violence, Bullying, War) , most of them from the World Health Organization social determinants of health. |
|
|
|
2589 <br /> |
|
|
|
2590 </p> |
|
|
|
2591 <p>A very important feature of MyGH is that it is GNU Health Federation. That is, if you want to share any of this data with your health professional in real-time, and they will be able to study it. |

2594 <h3>The PinePhone and the revolution in mobile computing</h3> |
|
|
|
2595 |
|
|
|
2596 <p>Of course, in a world of mobile phones and mobile computing, we need free/libre mobile applications. The problem I was facing until recently, that prevented me from writing MyGNUHealth, was the fact that there was no libre mobile environment. The mobile computing market has been dominated by Google and Apple, which both deliver proprietary operating systems, Android and iOS respectively. |
|
|
|
2597 <br /> |
|
|
|
2598 </p> |
|
|
|
2599 <p>The irruption of the <strong>Pine64</strong> community was the eye-opener and a game changer. A thriving community of talented people, determined to provide freedom in mobile computing. The Pine64 provides, among others, a smartphone (PinePhone), and a smartwatch (PineTime), and I have adopted both. |
|
|
|
2600 <br /> |
|
|
|
2601 </p> |
|
|
|
2602 |
|
|
|
2603 <p>I wrote an article some weeks ago (“Liberating our mobile computing”), where I mentioned why I have changed the Android phone to the PinePhone, and my watch to the PineTime. |
|
|
|
2604 <br /> |
|
|
|
2605 </p> |
|
|
|
2606 <p>Does the PinePhone have the best camera? Can we compare the PinePhone with Apple or Google products? It’s hard to compare a multi-billion dollar corporation with a fresh community oriented project. The business model, the technology components and the ethics behind are very different. |
|
|
|
2607 <br /> |
|
|
|
2608 </p> |
|
|
|
2609 <p>So, why making the move? I made the change because we, as a society, need to embrace a technology that is universal and that respects our freedom and privacy. A technology that if focus on the individual and not the corporation. That moves takes determination and commitment. There is a small price to pay, but freedom and privacy are priceless. |
|
|
|
2610 <br /> |
|
|
|
2611 </p> |
|
|
|
2612 <p>As a physician, I need to provide my patients the resources that use state-of-the-art technology, and, at the same time, guarantee the privacy of their sensitive medical information. Libre software and open standards are key in healthcare. When my patients choose free/libre software, they have full control. They also have the possibility to share it with me or with other health professionals, in real-time and with the highest levels of privacy. |
|
|
|
2613 <br /> |
|
|
|
2614 </p> |
|
|
|
2615 <p>We can only manage sensitive health data with technology that respects our privacy. In other words, we can not put our personal information in the hands of corporate interests. Choosing Libre Software and Hardware means much more than just technology. Libre Software means embracing solidarity and cooperation. It means sharing knowledge, code and time with others. It means embracing open science for the advancement of our societies, specially for those that need it most. |
|
|
|
2616 <br /> |
|
|
|
2617 </p> |
|
|
|
2618 <p>MyGNUHealth will be included by default in many operating systems and distributions, so you don’t have to worry about the technical details. Just use your health companion! If your operating system does not have MyGH in their repositories, please ask them to include it. |
|
|
|
2619 <br /> |
|
|
|
2620 </p> |
|
|
|
2621 <p>Governments, institutions, and health professional need affordable technology that respects their citizens freedom. We need you to be part of this eHealth revolution. |
|
|
|
2622 <br /> |
|
|
|
2623 </p> |
|
|
|
2624 <p>Happy and healthy hacking! |

|
2738 <p>Of course, in a world of mobile phones and mobile computing, we need free/libre mobile applications. The problem I was facing until recently, that prevented me from writing MyGNUHealth, was the fact that there was no libre mobile environment. The mobile computing market has been dominated by Google and Apple, which both deliver proprietary operating systems, Android and iOS respectively.</p> |

|
2742 <p>The irruption of the <strong>Pine64</strong> community was the eye-opener and a game changer. A thriving community of talented people, determined to provide freedom in mobile computing. The Pine64 provides, among others, a smartphone (<strong>PinePhone</strong>), and a smartwatch (<strong>PineTime</strong>), and I have adopted both. </p> |

2764 <p>I wrote an article some weeks ago (“<a href="https://meanmicio.org/2021/06/04/liberating-our-mobile-computing/">Liberating our mobile computing”)</a>, where I mentioned why I have changed the Android phone to the PinePhone, and my watch to the PineTime.</p> |
|
|
|
2765 |
|
|
|
2766 |
|
|
|
2767 |
|
|
|
2768 <p>Does the PinePhone have the best camera? Can we compare the PinePhone with Apple or Google products? It’s hard to compare a multi-billion dollar corporation with a fresh, community-oriented project. The business model, the technology components and the ethics behind are very different. </p> |
|
|
|
2769 |
|
|
|
2770 |
|
|
|
2771 |
|
|
|
2772 <p>So, why making the move? I made the change because we, as a society, need to embrace a technology that is universal and that respects our freedom and privacy. A technology that focuses on the individual and not in the corporation. That moves takes determination and commitment. There is a small price to pay, but freedom and privacy are priceless.</p> |

2794 <p>As a physician, I need to provide my patients the resources that use state-of-the-art technology, and, at the same time, guarantee the privacy of their sensitive medical information. Libre software and open standards are key in healthcare. When my patients choose free/libre software, they have full control. They also have the possibility to share it with me or with other health professionals, in real-time and with the highest levels of privacy.</p> |
|
|
|
2795 |
|
|
|
2796 |
|
|
|
2797 |
|
|
|
2798 <p>We can only manage sensitive health data with technology that respects our privacy. In other words, we can not put our personal information in the hands of corporate interests. Choosing Libre Software and Hardware means much more than just technology. Libre Software means embracing solidarity and cooperation. It means sharing knowledge, code and time with others. It means embracing open science for the advancement of our societies, specially for those that need it most.</p> |

|
2802 <p>MyGNUHealth will be included by default in many operating systems and distributions, so you don’t have to worry about the technical details. Just use your health companion! If your operating system does not have MyGH in their repositories, please ask them to include it.</p> |

2804 |

2847 <description> <p>This version of TeXmacs consolidates many developments that took place in the last decade. Most importantly, the interface is now based on Qt, which allowed us develop native versions for Linux, MacOS, and Windows. TeXmacs has evolved from a scientific text editor into a scientific office suite, with an integrated presentation mode, technical drawing editor, versioning tools, bibliography tool, etc. The typesetting quality has continued to improve with a better support of microtypography and a large variety of fonts. The converters for LaTeX and Html have also been further perfected and TeXmacs now comes with a native support for Pdf.<br /> |

2856 <description> <p>GNU Parallel 20210622 ('Protasevich') [stable] has been released. It is available for download at: lbry://@GnuParallel:4 |
|
|
|
2857 <br /> |
|
|
|
2858 </p> |
|
|
|
2859 <p>No new functionality was introduced so this is a good candidate for a stable release. |

2862 <p>Please help spreading GNU Parallel by making a testimonial video like Juan Sierra Pons: <a href="http://www.elsotanillo.net/wp-content/uploads/GnuParallel_JuanSierraPons.mp4">http://www.elsotanillo.net/wp-content/uploads/GnuParallel_JuanSierraPons.mp4</a> |

|
2863 <br /> |
|
|
|
2864 </p> |
|
|
|
2865 <p>It does not have to be as detailed as Juan's. It is perfectly fine if you just say your name, and what field you are using GNU Parallel for. |

2919 <h2>About GNU Parallel</h2> |
|
|
|
2920 |
|
|
|
2921 <p>GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel. |
|
|
|
2922 <br /> |
|
|
|
2923 </p> |
|
|
|
2924 <p>If you use xargs and tee today you will find GNU Parallel very easy to use as GNU Parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU Parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU Parallel can even replace nested loops. |
|
|
|
2925 <br /> |
|
|
|
2926 </p> |
|
|
|
2927 <p>GNU Parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU Parallel as input for other programs. |
|
|
|
2928 <br /> |
|
|
|
2929 </p> |
|
|
|
2930 <p>For example you can run this to convert all jpeg files into png and gif files and have a progress bar: |
|
|
|
2931 <br /> |
|
|
|
2932 </p> |
|
|
|
2933 <p> parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif |
|
|
|
2934 <br /> |
|
|
|
2935 </p> |
|
|
|
2936 <p>Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs: |
|
|
|
2937 <br /> |
|
|
|
2938 </p> |
|
|
|
2939 <p> find . -name '*.jpg' | |
|
|
|
2940 <br /> |
|
|
|
2941 parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200 |
|

3015 <h2>About GNU SQL</h2> |
|
|
|
3016 |
|
|
|
3017 <p>GNU sql aims to give a simple, unified interface for accessing databases through all the different databases' command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and port number), size (database and table size), and running queries. |
|
|
|
3018 <br /> |
|
|
|
3019 </p> |
|
|
|
3020 <p>The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell. |

|
|
|
3031 |
|
|
|
3032 <p>GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.<br /> |

|
|
|
3051 <description> <p>There have been a number of different project operated sources of |
|
|
|
3052 substitutes, for the last couple of years the default source of |
|
|
|
3053 substitutes has been <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> (with a few |
|
|
|
3054 different URLs).</p><p>Now, in addition to <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a>, |
|
|
|
3055 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> is a default substitute |
|
|
|
3056 server.</p><p>Put that way, this development maybe doesn't sound particularly |
|
|
|
3057 interesting. Why is a second substitute server useful? There's some |
|
|
|
3058 thoughts on that exact question in the next section. If you're just |
|
|
|
3059 interested in how to use (or how not to use) substitutes from |
|
|
|
3060 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a>, then you can just skip |
|
|
|
3061 ahead to the last section.</p><h1>Why a second source of substitutes?</h1><p>This change is an important milestone, following on from the work that |
|
|
|
3062 started on the <a href="https://guix.gnu.org/en/blog/2021/building-derivations-how-complicated-can-it-be/">Guix Build Coordinator towards the start of |
|
|
|
3063 2020</a>.</p><p>Back in 2020, the substitute availability from |
|
|
|
3064 <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> was often an issue. There seemed |
|
|
|
3065 to be a number of contributing factors, including some parts of the |
|
|
|
3066 architecture. Without going too much in to the details of the issues, |
|
|
|
3067 aspects of the design of the Guix Build Coordinator were specifically |
|
|
|
3068 meant to avoid some of these issues.</p><p>While there were some very positive results from testing back in 2020, |
|
|
|
3069 it's taken so long to bring the substitute availability benefits to |
|
|
|
3070 general users of Guix that <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> has |
|
|
|
3071 <a href="https://guix.gnu.org/en/blog/2021/cuirass-10-released/">changed and improved significantly in the meantime</a>. |
|
|
|
3072 This means that any benefits in terms of substitute availability are |
|
|
|
3073 less significant now.</p><p>One clearer benefit of just having two independent sources of |
|
|
|
3074 substitutes is redundancy. While the availability of |
|
|
|
3075 <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> has been very high (in my opinion), |
|
|
|
3076 having a second independent substitute server should mean that if |
|
|
|
3077 there's a future issue with users accessing either source of |
|
|
|
3078 substitutes, the disruption should be reduced.</p><p>I'm also excited about the new possibilities offered by having a |
|
|
|
3079 second substitute server, particularly one using the Guix Build |
|
|
|
3080 Coordinator to manage the builds.</p><p>Substitutes for the Hurd is already something that's <a href="https://lists.gnu.org/archive/html/guix-devel/2021-03/msg00074.html">been |
|
|
|
3081 prototyped</a>, so I'm hopeful that |
|
|
|
3082 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> can start using |
|
|
|
3083 <a href="https://guix.gnu.org/en/blog/2020/childhurds-and-substitutes/">childhurd VMs</a> to build things soon.</p><p>Looking a bit further forward, I think there's some benefits to be had |
|
|
|
3084 in doing further work on how the nar and narinfo files used for |
|
|
|
3085 substitutes are managed. There are some <a href="https://lists.gnu.org/archive/html/guix-devel/2021-02/msg00104.html">rough plans |
|
|
|
3086 already</a> on how to address the |
|
|
|
3087 retention of nars, and how to look at high performance mirrors.</p><p>Having two substitute servers is one step towards stronger trust |
|
|
|
3088 policies for substitutes (<a href="https://lists.gnu.org/archive/html/guix-devel/2020-06/msg00179.html">as discussed on guix-devel</a>, |
|
|
|
3089 where you would only use a substitute if both |
|
|
|
3090 <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a> and |
|
|
|
3091 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> have built it exactly |
|
|
|
3092 the same. This would help protect against the compromise of a single |
|
|
|
3093 substitute server.</p><h1>Using substitutes from bordeaux.guix.gnu.org</h1><p>If you're using Guix System, and haven't altered the default |
|
|
|
3094 substitute configuration, updating guix (via <code>guix pull</code>), |
|
|
|
3095 reconfiguring using the updated guix, and then restarting the |
|
|
|
3096 guix-daemon should enable substitutes from |
|
|
|
3097 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a>.</p><p>If the ACL is being managed manually, you might need to add the public |
|
|
|
3098 key for <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> manually as |
|
|
|
3099 well.</p><p>When using Guix on a foreign distribution with the default substitute |
|
|
|
3100 configuration, you'll need to run <code>guix pull</code> as root, then restart |
|
|
|
3101 the guix-daemon. You'll then need to add the public key for |
|
|
|
3102 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> to the ACL.</p><pre><code class="language-sh">guix archive --authorize &lt; /root/.config/guix/current/share/guix/bordeaux.guix.gnu.org.pub</code></pre><p>If you want to just use <a href="https://ci.guix.gnu.org">ci.guix.gnu.org</a>, or |
|
|
|
3103 <a href="https://bordeaux.guix.gnu.org">bordeaux.guix.gnu.org</a> for that matter, you'll |
|
|
|
3104 need to adjust the substitute urls configuration for the guix-daemon |
|
|
|
3105 to just refer to the substitute servers you want to use.</p> </description> |

|
|
|
3119 <h3>New bucket cache</h3> |

3124 <h3>Change in the mmap prereading strategy</h3> |
|
|
|
3125 |
|
|
|
3126 <p>Pre-reading of the memory mapper regions, introduced in version 1.19 can be advantageous only when doing intensive look-ups on a read-only |
|
|
|
3127 <br /> |
|
|
|
3128 database. It degrades performance otherwise, especially if doing multiple inserts. Therefore, this version introduces a new flag |
|
|
|
3129 <br /> |
|
|
|
3130 to gdbm_open: GDBM_PREREAD. When given, it enables pre-reading of memory mapped regions. (<a href="https://github.com/Perl/perl5/issues/18884">details</a>)<br /> |

3149 <description> <p>Last week, <a href="https://hpc.guix.info">we at Guix-HPC</a> published <a href="https://hpc.guix.info/events/2021/atelier-reproductibilit%C3%A9-environnements/">videos of |
|
|
|
3150 a workshop on reproducible software |
|
|
|
3151 environments</a> |
|
|
|
3152 we organized on-line. The videos are well worth watching—especially if |
|
|
|
3153 you’re into reproducible research, and especially if you speak French or |
|
|
|
3154 want to practice. This post, though, is more of a meta-post: it’s about |
|
|
|
3155 how we processed these videos. “A workshop on reproducibility <em>ought to |
|
|
|
3156 have</em> a reproducible video pipeline”, we thought. So this is what we |
|
|
|
3157 <a href="https://gitlab.inria.fr/guix-hpc/website/-/blob/master/doc/atelier-reproductibilit%C3%A9/render-videos.scm">did</a>!</p><h1>From BigBlueButton to WebM</h1><p>Over the last year and half, perhaps you had the “opportunity” to |
|
|
|
3158 participate in an on-line conference, or even to organize one. If so, |
|
|
|
3159 chances are that you already know |
|
|
|
3160 <a href="https://bigbluebutton.org/">BigBlueButton</a> (BBB), the free software |
|
|
|
3161 video conferencing suite initially designed for on-line teaching. In a |
|
|
|
3162 nutshell, it allows participants to chat (audio, video, and keyboard), |
|
|
|
3163 and speakers can share their screen or a PDF slide deck. Organizers can |
|
|
|
3164 also record the session.</p><p>BBB then creates a link to recorded sessions with a custom JavaScript |
|
|
|
3165 player that replays everything: typed chat, audio and video (webcams), |
|
|
|
3166 shared screens, and slide decks. This BBB replay a bit too rough though |
|
|
|
3167 and often not the thing you’d like to publish after the conference. |
|
|
|
3168 Instead, you’d rather do a bit of editing: adjusting the start and end |
|
|
|
3169 time of each talk, removing live chat from what’s displayed (which |
|
|
|
3170 allows you to remove info that personally identifies participants, |
|
|
|
3171 too!), and so forth. Turns out this kind of post-processing is a bit of |
|
|
|
3172 work, primarily because BBB does “the right thing” of recording each |
|
|
|
3173 stream separately, in the most appropriate form: webcam and screen |
|
|
|
3174 shares are recorded as separate videos, chat is recorded as text with |
|
|
|
3175 timings, slide decks is recorded as a bunch of PNGs plus timings, and |
|
|
|
3176 then there’s a bunch of XML files with metadata putting it all together.</p><p>Anyway, with a bit of searching, we quickly found the handy |
|
|
|
3177 <a href="https://github.com/plugorgau/bbb-render">bbb-render</a> tool, which can |
|
|
|
3178 first |
|
|
|
3179 <a href="https://github.com/plugorgau/bbb-render/blob/master/download.py">download</a> |
|
|
|
3180 all these files and then |
|
|
|
3181 <a href="https://github.com/plugorgau/bbb-render/blob/master/make-xges.py">assemble</a> |
|
|
|
3182 them using the Python interface to the <a href="https://gstreamer.freedesktop.org/documentation/gst-editing-services/index.html">GStreamer Editing Services |
|
|
|
3183 (GES)</a>. |
|
|
|
3184 Good thing: we don’t have to figure out all these things; we “just” have |
|
|
|
3185 to run these two scripts in an environment with the right dependencies. |
|
|
|
3186 And guess what: we know of a great tool to control execution |
|
|
|
3187 environments!</p><h1>A “deployment-aware Makefile”</h1><p>So we have a process that takes input files—those PNGs, videos, and XML |
|
|
|
3188 files—and produces output files—WebM video files. As developers we |
|
|
|
3189 immediately recognize a pattern and the timeless tool to deal with it: |
|
|
|
3190 <a href="https://www.gnu.org/software/make"><code>make</code></a>. The web already seems to |
|
|
|
3191 contain countless BBB post-processing makefiles (and shell scripts, |
|
|
|
3192 too). We were going to contribute to this while we suddenly realized |
|
|
|
3193 that we know of <em>another</em> great tool to express such processes: Guix! |
|
|
|
3194 Bonus: while a makefile would address just the tip of the |
|
|
|
3195 iceberg—running bbb-render—Guix can also take care of the tedious task |
|
|
|
3196 of deploying the <em>right</em> environment to run bbb-render in.</p><p>What we did was to write some sort of a <em>deployment-aware makefile</em>. |
|
|
|
3197 It’s still a relatively unconventional way to use Guix, but one that’s |
|
|
|
3198 very convenient. We’re talking about videos, but really, you could use |
|

3203 the videos with:</p><pre><code>guix build -m render-videos.scm</code></pre><p>Overall, the file defines a bunch of functions (<em>procedures</em> in |

3204 traditional Scheme parlance), each of which takes input files and |

3205 produces output files. More accurately, these functions returns objects |

|
|
|
3289 raw data, a start and end time, and produces a <code>video.ges</code> file. There |
|
|
|
3290 are three key elements here:</p><ol><li><a href="https://guix.gnu.org/manual/en/html_node/G_002dExpressions.html#index-computed_002dfile"><code>computed-file</code></a> |
|
|
|
3291 is a function to produce a file, <code>video.ges</code> in this case, by |
|
|
|
3292 running the code you give it as its second argument—the <em>recipe</em>, |
|
|
|
3293 in makefile terms.</li><li>The recipe passed to <code>computed-file</code> is a |
|
|
|
3294 <a href="https://guix.gnu.org/manual/en/html_node/G_002dExpressions.html"><em>G-expression</em></a> |
|
|
|
3295 (or “gexp”), introduced by this fancy <code>#~</code> (hash tilde) notation. |
|
|
|
3296 G-expressions are a way to <em>stage</em> code, to mark it for eventual |
|
|
|
3297 execution. Indeed, that code will only be executed if and when we |
|
|
|
3298 run <code>guix build</code> (without <code>--dry-run</code>), and only if the result is |
|
|
|
3299 not already in <a href="https://guix.gnu.org/manual/en/html_node/The-Store.html">the |
|
|
|
3300 store</a>.</li><li>The gexp refers to <code>rendering-profile</code>, to <code>bbb-render</code>, to |
|
|
|
3301 <code>bbb-data</code> and so on by <em>escaping</em> with the <code>#+</code> or <code>#$</code> syntax |
|
|
|
3302 (they’re equivalent, unless doing cross-compilation). During |
|
|
|
3303 build, these reference items in the store, such as |
|
|
|
3304 <code>/gnu/store/…-bbb-render</code>, which is itself the result of “building” |
|
|
|
3305 the origin we’ve seen above. The <code>#$output</code> reference corresponds |
|
|
|
3306 to the build result of this <code>computed-file</code>, the complete file name |
|
|
|
3307 of <code>video.ges</code> under <code>/gnu/store</code>.</li></ol><p>That’s quite a lot already! Of course, this real-world example is |
|
|
|
3308 more intimidating than the toy examples you’d find in the manual, but |
|
|
|
3309 really, pretty much everything’s there. Let’s see in more detail at |
|
|
|
3310 what’s inside this gexp.</p><p>The gexp first imports a bunch of helper modules with <a href="https://guix.gnu.org/manual/en/html_node/Build-Utilities.html">build |
|
|
|
3311 utilities</a> |
|
|
|
3312 and tools to manipulate profiles and search path environment variables. |
|
|
|
3313 The <code>for-each</code> call iterates over search path environment |
|
|
|
3314 variables—<code>PATH</code>, <code>PYTHONPATH</code>, and so on—, setting them so that the |
|
|
|
3315 <code>python</code> command is found and so that the needed Python modules are |
|
|
|
3316 found.</p><p>The <code>with-imported-modules</code> form above indicates that the <code>(guix build utils)</code> and <code>(guix profiles)</code> modules, which are part of Guix, along |
|
|
|
3317 with their dependencies (their <em>closure</em>), need to be imported in the |
|
|
|
3318 build environment. What about <code>with-extensions</code>? Those <code>(guix …)</code> |
|
|
|
3319 module indirectly depend on additional modules, provided by the |
|
|
|
3320 <code>guile-gcrypt</code> package, hence this spec.</p><p>Next comes the |
|
|
|
3321 <a href="https://gitlab.inria.fr/guix-hpc/website/-/blob/6977da4618814c790e767618da5cf9ec2cab0742/doc/atelier-reproductibilit%C3%A9/render-videos.scm#L77-106"><code>ges-&gt;webm</code></a> |
|
|
|
3322 function which, as the name implies, takes a <code>.ges</code> file and produces a |
|
|
|
3323 WebM video file by invoking <code>ges-launch-1.0</code>. The end result is a video |
|
|
|
3324 containing the recording’s audio, the webcam and screen share (or slide |
|
|
|
3325 deck), but not the chat.</p><h1>Opening and closing</h1><p>We have a WebM video, so we’re pretty much done, right? But… we’d also |
|
|
|
3326 like to have an opening, showing the talk title and the speaker’s name, |
|
|
|
3327 as well as a closing. How do we get that done?</p><p>Perhaps a bit of a sledgehammer, but it turns out that we chose to |
|

3328 produce those still images with LaTeX/Beamer, from |

|
|
|
3332 function that takes a template <code>.tex</code> file, a speaker name and |
|
|
|
3333 title. It copies the template, replaces placeholders with the |
|
|
|
3334 speaker name and title, and runs <code>pdflatex</code> to produce the PDF.</li><li>The |

|
|
|
3337 takes that JPEG and invokes <code>ffmpeg</code> to render it as WebM, with the |
|
|
|
3338 right resolution, frame rate, and audio track.</li></ol><p>With that in place, we define a sweet and small function that produces |

3339 the opening WebM file for a given talk:</p><pre><code class="language-scheme">(define (opening title speaker) |

3346 that given a talk, an opening, and a closing, concatenates them by |
|
|
|
3347 invoking <code>ffmpeg</code>.</p><h1>Putting it all together</h1><p>Now we have all the building blocks!</p><p>We use |

|
3396 with videos”, and that’s right! It’s also worth mentioning another |
|
|
|
3397 approach: <a href="https://lang.video/">Racket’s video language</a>, which is |
|
|
|
3398 designed to manipulate video abstractions, similar to GES but with a |
|
|
|
3399 sweet high-level functional interface.</p><p>But look, this one’s different: it’s |
|
|
|
3400 self-contained, it’s reproducible, and it has the right abstraction |
|
|
|
3401 level. Self-contained is a big thing; it means you can run it and it |
|
|
|
3402 knows what software to deploy, what environment variables to set, and so |
|
|
|
3403 on, for each step of the pipeline. Granted, it could be simplified with |
|
|
|
3404 appropriate high-level interfaces in Guix. But remember: the |
|
|
|
3405 alternative is a makefile (“deployment-unaware”) completed by a <code>README</code> |
|
|
|
3406 file giving a vague idea of the dependencies needed. The reproducible |
|

3407 bit is pretty nice too (especially for a workshop <em>on</em> reproducibility). |
|
|
|
3408 It also means there’s caching: videos or intermediate byproducts already |
|
|
|
3409 in the store don’t need to be recomputed. Last, we have access to a |
|
|
|
3410 general-purpose programming language where we can <em>build abstractions</em>, |
|
|
|
3411 such as the <code>&lt;talk&gt;</code> data type, that makes the whole thing more pleasant |
|
|
|
3412 to work with and more maintainable.</p><p>Hopefully that’ll inspire you to have a reproducible video pipeline for |
|
|
|
3413 your next on-line event, or maybe that’ll inspire you to replace your |
|
|
|
3414 old makefile and shelly habits for data processing!</p><p>High-performance computing (HPC) people might be wondering how to go |
|
|
|
3415 from here and build “computing-resource-aware” or |
|
|
|
3416 “storage-resource-aware” pipelines where each computing step could be |
|
|
|
3417 submitted to the job scheduler of an HPC cluster and use distributed |
|
|
|
3418 file systems for intermediate results rather than <code>/gnu/store</code>. If |
|
|
|
3419 you’re one of these folks, do take a look at how the <a href="https://guixwl.org/">Guix Workflow |
|
|
|
3420 Language</a> addresses these issues.</p><h1>Acknowledgments</h1><p>Thanks to Konrad Hinsen for valuable feedback on an earlier draft.</p><h4>About GNU Guix</h4><p><a href="https://guix.gnu.org">GNU Guix</a> is a transactional package manager and |

3472 <p>It’s a great day for Bangladesh. It’s a great day for public health! Today, <a href="https://www.gnusolidario.org">GNU Solidario</a> and the International Federation of Medical Students Association, <a href="http://ifmsabd.org/">IFMSA Bangladesh</a>, have signed an initial <strong>5-year</strong> partnership on the grounds of the <strong>GNU Health Alliance of Academic and Research Institutions</strong>.</p> |
|
|
|
3473 |
|
|
|
3474 |
|
|
|
3475 |
|
|
|
3476 <p>IFMSA Bangladesh is a non-for-profit, non-political organization that comprises <strong>3500+ medical students from over 65 schools of Medicine across Bangladesh.</strong> They are a solid organization, very well organized, with different standing committees and support divisions. </p> |
|
|
|
3477 |
|
|
|
3478 |
|
|
|
3479 |
|
|
|
3480 <p>IFMSA vision and mission fits very well with those of GNU Solidario advancement of <strong>Social Medicine</strong>. IFMSA has projects on Public Health (reproductive health; personal hygiene; cardiovascular disease and cancer prevention, … ), Human rights and peace (campaigns to end violence against women; protection of the underprivileged elders and children.. ). I am positive the GNU Health ecosystem will help them reach their goals in each of their projects!</p> |
|

|
3481 |
|
|
|
3482 |
|
|
|
3483 |
|
|
|
3484 <p>The GNU Health Alliance of Academic and Research Institutions is extremely happy to have IFMSA Bangladesh as a member. IFMSA Bangladesh joins now a group of outstanding researchers and institutions that have made phenomenal advancements in health informatics and contributions to public health. Some examples:</p> |

3486 |
|
|
|
3487 |
|
|
|
3488 <ul><li>The <strong>National University of Entre RÃos (UNER) </strong>has been awarded the project to use GNU Health as a real-time observatory for the <strong>COVID-19</strong> pandemic, by the Government of Argentina. In the context of the GNU Health Alliance, UNER has also developed the oral health package for GNU Health; and implemented the GNU Health Hospital Management Information System component in many public health care institutions in the country. The team from the UNER has traveled to Cameroon to implement GNU Health HMIS in several health facilities in the country, as well as training their health professionals.</li><li><strong>Thymbra</strong> Healthcare (R&amp;D Labs) has contributed the <strong>medical genetics</strong> and <strong>precision medicine</strong>. Currently, Thymbra is focused on <strong>MyGNUHealth</strong>, the GNU Health Personal Health Record (PHR) for <strong>KDE</strong> plasma mobile and desktops devices, and working on the integration of MyGNUHealth with the <strong>PinePhone</strong>.</li><li><strong>Khadas</strong> has signed an agreement to work on with the GNU Health community in <strong>Artificial Intelligence</strong> and medical imaging, as well on integrating Single Board Computers (SBCs) with GNU Health (the GNU Health in a Box project)</li></ul> |

|
3489 |

|
|
3490 |
|
|
|
3491 |
|
|
|
3492 <p>The fact that an association of 3500+ medical students embrace GNU Health means that all these bright future doctors from Bangladesh will also bear the ethics and philosophy of Libre Software to their communities. Public Health can not be run by private corporations, nor by proprietary software.</p> |
|
|
|
3493 |
|
|
|
3494 |
|
|
|
3495 |
|
|
|
3496 <p>IFMSA has 5 years ahead to make a wonderful revolution in the public health care system. Health institutions will be able to implement state-of-the-art health informatics. Medical students can learn GNU Health inside-out, and conduct workshops across the country in the Libre digital health ecosystem. Most importantly, I am positive GNU Health will provide a wonderful opportunity to improve the health promotion and disease prevention campaigns in Bangladesh.</p> |

3500 <p>As the president of GNU Solidario, I am truly honored and looking forward to start collaborating with our colleagues from Bangladesh, and, when the pandemic is over, be able to meet them in person. </p> |

3502 |

|
|
3503 |

|
3504 <p>My most sincere appreciation to IFMSA Bangladesh for becoming part of the GNU Health community. To the 3500+ members, a very warm welcome! </p> |

3548 <description> <p>GNU/EDMA 0.19.1 has been released as an Alpha Version. This version tries to fix the long standing issue with 64bits platforms. |
|
|
|
3549 <br /> |
|
|
|
3550 </p> |
|
|
|
3551 <p>In order to fix that problem this version adds a dependency on `libffi`. |

3812 <title>GNU Health: Liberating our mobile computing</title> |

3815 <description> <p>Last week I got the PineTime, a free/libre smartwatch. In the past months, I’ve been working on MyGNUHealth and porting it to the PinePhone.</p> |
|
|
|
3816 |
|
|
|
3817 |
|
|
|
3818 |
|
|
|
3819 <p>Why doing so? Because running free/libre operating systems and having control of the applications on your mobile phones and wearables is the right thing to do.</p> |

|
|
3827 <p>Yesterday, I told myself: “This is the day to move away from Android and take control over my phone”. And I made the switch. Now I am using a PinePhone on Manjaro running KDE plasma mobile. I have also switched my smartwatch to the PineTime.</p> |
|
|
|
3828 |
|
|
|
3829 |
|
|
|
3830 |
|
|
|
3831 <p>The mobile phone and smartwatch were the last pieces of hardware and software to liberate. All my computing is now libre. No proprietary operating systems, no closed-source applications. Not on my laptop, not in my desktop, not on my phone.</p> |

3835 <h3>Facing and overcoming the social pressure</h3> |
|
|
|
3836 |
|
|
|
3837 |
|
|
|
3838 |
|
|
|
3839 <p>At the moment I ditched Android, I felt an immense sense of relief and happiness. It took me back 30 years ago, early FreeBSD and GNU/Linux times, being in control of every component of my computer.</p> |
|
|
|
3840 |
|
|
|
3841 |
|
|
|
3842 |
|
|
|
3843 <p>We can not put our daily life activities, electronic transactions and data in the hands of the corporations. Android phones shipped today are full of “bloatware” and closed-source applications. We can safely call most of those applications spyware. </p> |
|
|
|
3844 |
|
|
|
3845 |
|
|
|
3846 |
|
|
|
3847 <p>The PinePhone is a libre computer, with a phone. All the applications are Libre Software. I have SSH, most of the cool KDE plasma applications I enjoy in the desktop, I can have them now in my pocket. Again, most importantly, I am free.</p> |
|
|
|
3848 |
|
|
|
3849 |
|
|
|
3850 |
|
|
|
3851 <p>Of course, freedom comes with a price. The price to face social and corporate pressure. For instance, somebody asked me yesterday how to deal with banking without the app. My answer was, I never used an app for banking. Running a proprietary financial application is shooting at the heart of your privacy. If your bank does not let you do your transactions from any standard web browser, then change your bank. Quick digression… the financial system and the big technological corporations are desperately trying to get rid of good all coins and bills. This is yet another attack on our privacy. Nobody needs to know when, where and what I buy. </p> |
|
|
|
3852 |
|
|
|
3853 |

|
3854 |

|
3855 <h3>A brighter future depends on us</h3> |
|
|
|
3856 |
|
|
|
3857 |
|
|
|
3858 |
|
|
|
3859 <p>Some people might argue that this technology might not be ready for prime time, yet. I would say that I am ok with it, and the more we join, the more feedback we provide, and the better end result we’ll get.</p> |
|
|
|
3860 |
|
|
|
3861 |
|
|
|
3862 |
|
|
|
3863 <p>The Pine64 project is mainly a community-oriented ecosystem. Its hardware, operating system and applications are from the community and for the community. I am developing MyGNUHealth Personal Health Record to be run on KDE Plasma, both for desktop and for the PinePhone and other Libre mobile devices. It is my commitment with freedom, privacy and universal healthcare to deliver health informatics in Libre, privacy focused platforms that anyone can adopt.</p> |

3871 <p>It depends on you to be prisoner of the corporation and massive surveillance systems, or to be in full control of your programming, health information and life. It takes commitment to achieve it… some components might be too bleeding edge or the camera might not have the highest resolutions and you won’t have the Whatsapp “app” (removing that application would actually be a blessing). It’s a very small price to pay for freedom and privacy. It’s a very small price to pay for the advancement of our society.</p> |

3879 <p>It’s been many years since I’ve been in the look out for a truly libre phone. After many projects that succumbed, the PinePhone is the first one that has gained momentum. Please support the PinePhone project. Support KDE plasma mobile. Support Arch, Manjaro, openSUSE, FreeBSD or your favorite Libre operating system. Support those who make Libre convergent applications that can be run on mobile devices, like Kirigami. Support InfiniTime and any free/libre firmware for smartwatches, as well as their companions as Siglo or Amazfish.</p> |

3992 <h2>About GNU Parallel</h2> |
|
|
|
3993 |
|
|
|
3994 <p>GNU Parallel is a shell tool for executing jobs in parallel using one or more computers. A job can be a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. A job can also be a command that reads from a pipe. GNU Parallel can then split the input and pipe it into commands in parallel. |
|
|
|
3995 <br /> |
|
|
|
3996 </p> |
|
|
|
3997 <p>If you use xargs and tee today you will find GNU Parallel very easy to use as GNU Parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU Parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. GNU Parallel can even replace nested loops. |
|
|
|
3998 <br /> |
|
|
|
3999 </p> |
|
|
|
4000 <p>GNU Parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU Parallel as input for other programs. |
|
|
|
4001 <br /> |
|
|
|
4002 </p> |
|
|
|
4003 <p>For example you can run this to convert all jpeg files into png and gif files and have a progress bar: |
|
|
|
4004 <br /> |
|
|
|
4005 </p> |
|
|
|
4006 <p> parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif |
|
|
|
4007 <br /> |
|
|
|
4008 </p> |
|
|
|
4009 <p>Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs: |
|
|
|
4010 <br /> |
|
|
|
4011 </p> |
|
|
|
4012 <p> find . -name '*.jpg' | |
|
|
|
4013 <br /> |
|
|
|
4014 parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200 |
|

4088 <h2>About GNU SQL</h2> |
|
|
|
4089 |
|
|
|
4090 <p>GNU sql aims to give a simple, unified interface for accessing databases through all the different databases' command line clients. So far the focus has been on giving a common way to specify login information (protocol, username, password, hostname, and port number), size (database and table size), and running queries. |
|
|
|
4091 <br /> |
|
|
|
4092 </p> |
|
|
|
4093 <p>The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell. |

4103 <h2>About GNU Niceload</h2> |
|
|
|
4104 |
|
|
|
4105 <p>GNU niceload slows down a program when the computer load average (or other system activity) is above a certain limit. When the limit is reached the program will be suspended for some time. If the limit is a soft limit the program will be allowed to run for short amounts of time before being suspended again. If the limit is a hard limit the program will only be allowed to run when the system is below the limit.<br /> |
