Libtoolers!
The Libtool Team is pleased to announce the release of libtool 2.5.4.
GNU Libtool hides the complexity of using shared libraries behind a
consistent, portable interface. GNU Libtool ships with GNU libltdl, which
hides the complexity of loading dynamic runtime libraries (modules)
behind a consistent, portable interface.
There have been 49 commits by 16 people in the 8 weeks since 2.5.3.
See the NEWS below for a brief summary.
Thanks to everyone who has contributed!

Use a .sig file to verify that the corresponding file (without the
.sig suffix) is intact. First, be sure to download both the .sig file
and the corresponding tarball. Then, run a command like this:
gpg --verify libtool-2.5.4.tar.gz.sig
The signature should match the fingerprint of the following key:
pub rsa4096 2021-09-23 [SC]

uid Ileana Dumitrescu <ileanadumitrescu95@gmail.com>
If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.
gpg --locate-external-key ileanadumi95@protonmail.com

wget -q -O- 'https://savannah.gnu.org/project/release-gpgkeys.php?group=libtool&download=1' | gpg --import -
As a last resort to find the key, you can try the official GNU
keyring:
wget -q https://ftp.gnu.org/gnu/gnu-keyring.gpg
gpg --keyring gnu-keyring.gpg --verify libtool-2.5.4.tar.gz.sig

To understand the views of the Guix community we're running a survey that we'd love you to take part in! The Guix User and Contributor Survey is live now, and should take about 10 minutes to fill out. Perfect for doing with a cup of tea and a biscuit!
The Guix project continues to grow and change, with new contributors and users joining our community. We decided to run this survey as it's the best way to gather good quality feedback across the widest cross-section of the community. Of course, there's lots of interesting topics a survey could ask about! We decided to focus on how Guix is used, and how contributors take part in the project.
The survey is being run on LimeSurvey which is a Free Software project and has been used by many other projects for similar surveys. The survey's hosted on the LimeSurvey SaaS so that we don't have the additional task of operating the software. No personal data is asked for (e.g. email addresses), no tracking data is being collected (e.g. IP addresses) and the entries are anonymised.
We'll be making the results and the anonymised data available under the Creative Commons CCO: that way anyone can analyse the data for further insights.
We hope the results of the survey will be used to understand both the Guix project's strengths and areas we can improve. Which is why your input is so important. If you can, please take the survey!

This is a bugfix release for gnunet 0.22.1. It fixes some regressions and minor bugs.
The GPG key used to sign is: 3D11063C10F98D14BD24D1470B0998EF86F59B6A
Note that due to mirror synchronization, not all links may be functional early after the release. For direct access try https://ftp.gnu.org/gnu/gnunet/
NOTE: pacman v7 is currently in [libre-testing]; but it will be promoted to libre soon
from arch:
With the release of [version 7.0.0] pacman has added support for downloading packages as a separate user with dropped privileges.
For users with local repos however this might imply that the download
user does not have access to the files in question, which can be fixed
by assigning the files and folder to the alpm group and ensuring the
executable bit (+x) is set on the folders in question.
$ chown :alpm -R /path/to/local/repo
Remember to [merge the .pacnew] files to apply the new default.
Pacman also introduced [a change] to improve checksum stability for
git repos that utilize .gitattributes files. This might require a
one-time checksum change for PKGBUILDs that use git sources.

GNU Parallel 20241022 ('Sinwar Nasrallah') has been released. It is available for download at: lbry://@GnuParallel:4
Quote of the month:
GNU Parallel is one of the most helpful tools I've been using recently, and it's just something like: parallel -j4 'gzip {}' ::: folder/*.csv
-- Milton Pividori @miltondp@twitter
New in this release:
News about GNU Parallel:
GNU Parallel - For people who live life in the parallel lane.
If you like GNU Parallel record a video testimonial: Say who you are, what you use GNU Parallel for, how it helps you, and what you like most about it. Include a command that uses GNU Parallel if you feel like it.
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.
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.
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.
For example you can run this to convert all jpeg files into png and gif files and have a progress bar:
parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif
Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:
find . -name '*.jpg' |
parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200
You can find more about GNU Parallel at: http://www.gnu.org/s/parallel/

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.
The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.

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.

A security issue, known as CVE-2024-52867, has been identified in
guix-daemon
which allows for a local user to gain the privileges of any of the build users
and subsequently use this to manipulate the output of any build. You
are strongly advised to upgrade your daemon now (see instructions
below), especially on multi-user systems.
This exploit requires the ability to start a derivation build and the ability to run arbitrary code with access to the store in the root PID namespace on the machine the build occurs on. As such, this represents an increased risk primarily to multi-user systems and systems using dedicated privilege-separation users for various daemons: without special sandboxing measures, any process of theirs can take advantage of this vulnerability.
For a very long time, guix-daemon has helpfully made the outputs of failed
derivation builds
available
at the same location they were at in the build container. This has aided greatly
especially in situations where test suites require the package to already be
installed in order to run, as it allows one to re-run the test suite
interactively outside of the container when built with --keep-failed. This
transferral of store items from inside the chroot to the real store was
implemented with a simple rename, and no modification of the store item or
any files it may contain.
If an attacker starts a build of a derivation that creates a binary with the
setuid and/or setgid bit in an output directory, then, and the build fails, that
binary will be accessible unaltered for anybody on the system. The attacker or a
cooperating user can then execute the binary, gain the privileges, and from
there use a combination of signals and procfs to freeze a builder, open any file
it has open via /proc/$PID/fd, and overwrite it with whatever it wants. This
manipulation of builds can happen regardless of which user started the build, so
it can work not only for producing compromised outputs for commonly-used
programs before anybody else uses them, but also for compromising any builds
another user happens to start.
A related vulnerability was also discovered concerning the outputs of
successful builds. These were
moved -
also via rename() - outside of the container prior to having their
permissions, ownership, and timestamps
canonicalized. This
means that there also exists a window of time for a successful build's outputs
during which a setuid/setgid binary can be executed.
In general, any time that a build user running a build for some submitter can
get a setuid/setgid binary to a place the submitter can execute it, it is
possible for the submitter to use it to take over the build user. This situation
always occurs when --disable-chroot is passed to guix-daemon. This holds
even in the case where there are no dedicated build users, and builds happen
under the same user the daemon runs as, as happens during make check in the
guix repository. Consequently, if a permissive umask that allows execute
permission for untrusted users on directories all the way to a user's guix
checkout is used, an attacker can use that user's test-environment daemon to
gain control over their user while make check is running.
This security issue has been fixed by
two
commits. Users
should make sure they have updated to the second commit to be protected from
this vulnerability. Upgrade instructions are in the following section. If there
is a possibility that a failed build has left a setuid/setgid binary lying
around in the store by accident, run guix gc to remove all failed build
outputs.
The fix was accomplished by sanitizing the permissions of all files in a failed
build output prior to moving it to the store, and also by waiting to move
successful build outputs to the store until after their permissions had been
canonicalized. The sanitizing was done in such a way as to preserve as many
non-security-critical properties of failed build outputs as possible to aid in
debugging. After applying these two commits, the guix package in Guix was
updated
so that guix-daemon deployed using it would use the fixed version.
If you are using --disable-chroot, whether with dedicated build users or not,
make sure that access to your daemon's socket is restricted to trusted
users. This particularly affects anyone running make check and anyone running
on GNU/Hurd. The former should either manually remove execute permission for
untrusted users on their guix checkout or apply this
patch, which restricts access to the
test-environment daemon to the user running the tests. The latter should adjust
the ownership and permissions of /var/guix/daemon-socket, which can be done
for Guix System users using the new socket-directory-{perms,group,user} fields
in this patch.
A proof of concept is available at the end of this post. One can run this code with:
guix repl -- setuid-exposure-vuln-check.scmThis will output whether the current guix-daemon being used is vulnerable or
not. If it is not vulnerable, the last line will contain your system is not vulnerable, otherwise the last line will contain YOUR SYSTEM IS VULNERABLE.
Due to the severity of this security advisory, we strongly recommend
all users to upgrade their guix-daemon immediately.
For Guix System, the
procedure
is to reconfigure the system after a guix pull, either restarting
guix-daemon or rebooting. For example:
guix pull
sudo guix system reconfigure /run/current-system/configuration.scm
sudo herd restart guix-daemonwhere /run/current-system/configuration.scm is the current system
configuration but could, of course, be replaced by a system
configuration file of a user's choice.
For Guix running as a package manager on other distributions, one
needs to guix pull with sudo, as the guix-daemon runs as root,
and restart the guix-daemon service, as
documented.
For example, on a system using systemd to manage services, run:
sudo --login guix pull
sudo systemctl restart guix-daemon.serviceNote that for users with their distro's package of Guix (as opposed to having used the install script) you may need to take other steps or upgrade the Guix package as per other packages on your distro. Please consult the relevant documentation from your distro or contact the package maintainer for additional information or questions.
Even with the sandboxing features of modern kernels, it can be quite challenging to synthesize a situation in which two users on the same system who are determined to cooperate nevertheless cannot. Guix has an especially difficult job because it needs to not only realize such a situation, but also maintain the ability to interact with both users itself, while not allowing them to cooperate through itself in unintended ways. Keeping failed build outputs around for debugging introduced a vulnerability, but finding that vulnerability because of it enabled the discovery of an additional vulnerability that would have existed anyway, and prompted the use of mechanisms for securing access to the guix daemon.
I would like to thank Ludovic Courtès for giving feedback on these vulnerabilities and their fixes — discussion of which led to discovering the vulnerable time window with successful build outputs — and also for helping me to discover that my email server was broken.
Below is code to check if your guix-daemon is vulnerable to this exploit. Save
this file as setuid-exposure-vuln-check.scm and run following the instructions
above, in "Mitigation."
(use-modules (guix)
(srfi srfi-34))
(define maybe-setuid-file
;; Attempt to create a setuid file in the store, with one of the build
;; users as its owner.
(computed-file "maybe-setuid-file"
#~(begin
(call-with-output-file #$output (const #t))
(chmod #$output #o6000)
;; Failing causes guix-daemon to copy the output from
;; its temporary location back to the store.
(exit 1))))
(with-store store
(let* ((drv (run-with-store store
(lower-object maybe-setuid-file)))
(out (derivation->output-path drv)))
(guard (c (#t
(if (zero? (logand #o6000 (stat:perms (stat out))))
(format #t "~a is not setuid: your system is not \
vulnerable.~%"
out)
(format #t "~a is setuid: YOUR SYSTEM IS VULNERABLE.
Run 'guix gc' to remove that file and upgrade.~%"

Dear community:
We’re excited to announce the IX International GNU Health Conference, that will take place in beautiful Sicily, Italy, at the University of Palermo this December 15th.
The GNU Health Conference (GHCon) is the annual conference that brings together enthusiasts and developers of GNU Health, the Libre digital health ecosystem. The conference will have thematic sessions, lightning talks and implementation cases to get to know the GNU Health and other Free/Libre software communities from around the world.
We will show the upcoming features of the Health and Hospital Information System, standards, security, privacy, the GNU Health Federation and MyGNUHealth (the Personal Health Record).
The XVII International Workshop on eHealth in Emerging Economies (IWEEE) is about Social Medicine and addressing the reality of the underprivileged around the world. There will be workshops to debate, and share experiences from humanitarian organizations and from those working in field of Social Medicine.
In the evening we will announce and honor the winners of the GNU Health Social Medicine awards.
We are counting on you to get the most out of the conference. Most importantly, we want you to have fun, feel at home, and enjoy being part
of the GNU Health community.
Looking forward to seeing you in Sicily!
Happy Hacking!

The GNU Boot project previously found nonfree microcode in the first
RC1 release (in gnuboot-0.1-rc1_src.tar.xz to be exact).
This was announced in the "GNU Boot December 2023 News"
(https://lists.gnu.org/archive/html/gnuboot-announce/2023-12/msg00000.html). It
was fixed by re-making the affected tarball by hand with the nonfree
software removed and by contacting Canoeboot that had the same issue,
and by bug reporting and proposing patches to fix the issue in Guix as
well (they are still pending as we need to find a reviewer familiar
with Coreboot).
But recently we found a more problematic issue that also affects many
more distributions and all the previous GNU Boot release candidates.
The vboot source code used in Coreboot and in the vboot-utils package
available in many GNU/Linux distributions contains nonfree code in
their test data in tests/futility/data (nonfree microcode, nonfree
BIOS, nonfree Management Engine firmwares, etc).
So we had to re-release all the affected tarballs (like
gnuboot-0.1-rc1_src.tar.xz, gnuboot-0.1-rc2_src.tar.xz, etc).
We made and we improved the process along the way (we now store the
changes in tag inside our git repository and simply regenerate the
tarballs with the build system that is available for a given tag).
We are also in the process of contacting distributions and/or
coordinating with them and we also need help as there are many
distributions to contact.
To do that we started contacting the free GNU/Linux distros
(https://www.gnu.org/distros/free-distros.html) that ship the vboot
source code. We also contacted Replicant that is a free Android distro
that also ships vboot source code.
We also started to contact common distros that require certain
repositories to only have free software (so far we only contacted
Debian as that will help Trisquel fix the issue, but we also need to
contact Fedora for instance). Finding which distro to contact is made
much easier thanks to GNU's review of common distros policies
(https://www.gnu.org/distros/common-distros.html).
We coordinate that work on our bug report system at Savannah,
especially in the bug #66246
(https://savannah.gnu.org/bugs/index.php?66246).

I have decided to start using sourcehut for a few of my projects. The first projects landing there are bugz-mode and a68-mode, two Emacs modes. The first implements a quite efficient and comfortable interface to bugzilla. The second is a programming mode for Algol 68.
Let's see how it goes!
This is a bugfix release for gnunet 0.22.0. It addresses some issues in HELLO URI handling and formatting as well as regressions in the DHT subsystem along with other bug fixes.
The GPG key used to sign is: 3D11063C10F98D14BD24D1470B0998EF86F59B6A
Note that due to mirror synchronization, not all links may be functional early after the release. For direct access try https://ftp.gnu.org/gnu/gnunet/
It’s no news. They’re stealing the Internet from us and we must do something about it. What it used to be a fun, collaborative hacking space is now ruled by corporations and narcissistic billionaires. Proprietary centralized social networks have become a space for hate, discrimination and propaganda. The messages that you see are those that they want you to see. Your data is no longer yours. They have become a massive thought control machine. You read what they want you to read and, in the end, you will end up writing and doing what they want you to write and to do. It’s a matter of time and money, and they have both.
These corporate-driven social networks are deceiving. They make us fall into false assumptions in a distorted reality. This delusion hits both individuals and organizations. For instance, in GNU Solidario and GNU Health, we fight for Social Medicine and for the rights of human and non-human animals. When we want to share an event, to make a fundraising campaign or to denounce human or animal rights violations we want the message to reach out as many people as possible. We could think, why not share it with our followers on Twitter / X? Experience has it, corporate social networks have not really made a difference in the outcomes. They will promote or “shadow ban” the message depending on who wrote it. You can guess the results for those who fight against neoliberal capitalism.
Social pressure exists, and is not trivial to overcome. Many fear that leaving proprietary centralized social networks that have been using for years will result in losing the status and contacts they’ve built throughout the years. Again, it’s not really a big deal. And we have great news, there are decentralized, community-driven alternatives! Some of those alternatives are Mastodon, Friendica or Diaspora.

Internet is no longer fun or empathetic. It has become a hostile and toxic environment, the medium for corporations and elites that increase concentration of power, social gradient and create very unjust societies. They use our data to control individuals and governments. We certainly don’t want to be part of that.
It is our moral duty to bring back spirit of solidarity that RMS delivered in the late 80’s, and that made possible the GNU movement, the best operating systems, programming languages, web servers and database engines for everyone.

In the end, it is up to us to embrace federated, community driven social networks and free software applications. Millions of individuals, activists, free software projects, NGOs and even the European Union have already joined the Fediverse and Mastodon. It only takes an initial push to break the social pressure to set ourselves and our societies free.

It’s no news. They’re stealing the Internet from us and we must do something about it. What it used to be a fun, collaborative hacking space is now ruled by corporations and narcissistic billionaires. Proprietary centralized social networks have become a space for hate, discrimination and propaganda. The messages that you see are those that they want you to see. Your data is no longer yours. They have become a massive thought control machine. You read what they want you to read and, in the end, you will end up writing and doing what they want you to write and to do. It’s a matter of time and money, and they have both.
These corporate-driven social networks are deceiving. They make us fall into false assumptions in a distorted reality. This delusion hits both individuals and organizations. For instance, in GNU Solidario and GNU Health, we fight for Social Medicine and for the rights of human and non-human animals. When we want to share an event, to make a fundraising campaign or to denounce human or animal rights violations we want the message to reach out as many people as possible. We could think, why not share it with our followers on Twitter / X? Experience has it, corporate social networks have not really made a difference in the outcomes. They will promote or “shadow ban” the message depending on who wrote it. You can guess the results for those who fight against neoliberal capitalism.

Libtoolers!
The Libtool Team is pleased to announce the release of libtool 2.5.3.
GNU Libtool hides the complexity of using shared libraries behind a
consistent, portable interface. GNU Libtool ships with GNU libltdl, which
hides the complexity of loading dynamic runtime libraries (modules)
behind a consistent, portable interface.
There have been 14 commits by 2 people in the 27 days since 2.5.2.
See the NEWS below for a brief summary. An alpha and two beta releases
of GNU Libtool have been released prior to this stable release. Please
view the NEWS entries for those releases for a more complete summary of
the updates between stable releases 2.4.7 and 2.5.3.
Thanks to everyone who has contributed!
The following people contributed changes to this release:

uid Ileana Dumitrescu <ileanadumitrescu95@gmail.com>
If that command fails because you don't have the required public key,
or that public key has expired, try the following commands to retrieve
or refresh it, and then rerun the 'gpg --verify' command.
gpg --locate-external-key ileanadumi95@protonmail.com

** New features:
- Add 'aarch64' support to the file magic test, which allows for
shared libraries to be built with Mingw for aarch64.
** Bug fixes:
- The configure options --with-pic and --without-pic have been renamed
to --enable-pic and --disable-pic, respectively. The old names
--with-pic and --without-pic are still supported, though, for
backward compatibility.
- The configure option --with-aix-soname has been renamed to
--enable-aix-soname. The old name --with-aix-soname is still
supported, though, for backward compatibility.
- Fix conflicting warnings about AC_PROG_RANLIB.
- Document situations where -export-symbols does not work.
- Update FSF office address with URL in each file's license block.
- Add checks for aclocal in standalone.at and subproject.at test files
that report failures in Linux From Scratch and Darwin builds.
Enjoy!

GNU Parallel 20240922 ('Gold Apollo AR924') has been released. It is available for download at: lbry://@GnuParallel:4
Quote of the month:
Recently executed a flawless live data migration of ~2.4pb using GNU parallel for scale and bash scripts.
-- @mechanicker@twitter Dhruva
New in this release:
News about GNU Parallel:
GNU Parallel - For people who live life in the parallel lane.
If you like GNU Parallel record a video testimonial: Say who you are, what you use GNU Parallel for, how it helps you, and what you like most about it. Include a command that uses GNU Parallel if you feel like it.
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.
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.
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.
For example you can run this to convert all jpeg files into png and gif files and have a progress bar:
parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif
Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:
find . -name '*.jpg' |
parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200
You can find more about GNU Parallel at: http://www.gnu.org/s/parallel/
You can install GNU Parallel in just 10 seconds with:
$ (wget -O - pi.dk/3 || lynx -source pi.dk/3 || curl pi.dk/3/ || \
fetch -o - http://pi.dk/3 ) > install.sh

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.
The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.
When using GNU SQL for a publication please cite:

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.

We are pleased to announce the release of GNUnet 0.22.0.
GNUnet is an alternative network stack for building secure, decentralized and
privacy-preserving distributed applications.
Our goal is to replace the old insecure Internet protocol stack.
Starting from an application for secure publication of files, it has grown to
include all kinds of basic protocol components and applications towards the
creation of a GNU internet.
This is a new major release. It breaks protocol compatibility with the 0.21.x versions. Please be aware that Git master is thus henceforth (and has been for a while) INCOMPATIBLE with the 0.21.x GNUnet network, and interactions between old and new peers will result in issues. In terms of usability, users should be aware that there are still a number of known open issues in particular with respect to ease of use, but also some critical privacy issues especially for mobile users. Also, the nascent network is tiny and thus unlikely to provide good anonymity or extensive amounts of interesting information. As a result, the 0.22.0 release is still only suitable for early adopters with some reasonable pain tolerance .
The GPG key used to sign is: 3D11063C10F98D14BD24D1470B0998EF86F59B6A
Note that due to mirror synchronization, not all links might be functional early after the release. For direct access try http://ftp.gnu.org/gnu/gnunet/
A detailed list of changes can be found in the git log , the NEWS and the bug tracker . Noteworthy highlights are
In addition to this list, you may also want to consult our bug tracker at bugs.gnunet.org which lists about 190 more specific issues.
This release was the work of many people. The following people contributed code and were thus easily identified: Christian Grothoff, t3sserakt, TheJackiMonster, Pedram Fardzadeh, Shichao, fence, dvn, nullptrderef and Martin Schanzenbach.
Additionally there's a minor release of libgnunetchat 0.5.1 which fixes multiple issues to improve overall reliability.
A detailed list of changes can be found in the ChangeLog .
Utilizing latest changes in GNUnet and libgnunetchat, there's a new release of the messenger application bringing live chats which allow streaming your own voice or video with other contacts. This release requires libgnunetchat 0.5.1.
Keep in mind the application is still in development. So there may still be major bugs keeping you from getting a reliable connection. But if you encounter such issue, feel free to consult our bug tracker at bugs.gnunet.org .
Screen is a full-screen window manager that multiplexes a physical
terminal between several processes, typically interactive shells.
The 5.0.0 release includes the following changes to the previous
release 4.9.1:
- auth [on|off]
Provides password protection
- status [top|up|down|bottom] [left|right]
The status window by default is in bottom-left corner.
This command can move status messages to any corner of the screen.
- truecolor [on|off]
- multiinput
Input to multiple windows at the same time
- time
- debug
- password
- maxwin
- nethack
- Screen buffers ESC keypresses indefinitely
- Crashes after passing through a zmodem transfer
- Fix double -U issue
Release is available for download:

Please report any bugs or regressions.
Thanks to everyone who contributed to this release.
Cheers,

This project aimed to implement a new communicator for GNUnet's Transport Next Generation (TNG) using the HTTP/3 protocol.
We chose ngtcp2 and nghttp3 for their stability and adherence to RFC standards. I began by studying communicator fundamentals and analyzing relevant code examples. I then created a QUIC communicator using libngtcp2, implementing essential communication features. Building on this, I integrated libnghttp3 to support HTTP/3 layer communication. After establishing basic uni-directional communication, I proceeded to implement bi-directional capabilities. With the help and guidance of my mentors, I completed the above work, including the selection and design of message transmission methods and the implementation of code.
We have two branches, dev/shichao/http3 for basic communication and dev/shichao/http3bidirect for bi-directional communication. They can pass the basic tests. However, we found that there were occasional failures during the test. We currently assume that this is caused by the test harness not being able to process the received data packets in time.
There are still many areas that can be improved in the HTTP/3 communicator, such as using CID map instead of IP address map. In addition, in bi-directional communication, the server's sending rate is slightly lower than the client's transmission rate, and this will be optimized in the future. Finally, integrating the Peer Identity into the TLS handshake in order to authenticate the peers is a natural feature to implement.
All the code is available upstream in the master branch and will be available with the next release.
Initially, I was unfamiliar with the ngtcp2 and nghttp3 libraries. While there were some examples available, I found limited guidance for more advanced usage. Through careful study and experimentation, I gradually gained a deeper understanding of these libraries. But in this process, I have a deeper understanding of QUIC and HTTP/3 protocols, and also improved my coding skills.

News about GNU Parallel:
GNU Parallel - For people who live life in the parallel lane.
If you like GNU Parallel record a video testimonial: Say who you are, what you use GNU Parallel for, how it helps you, and what you like most about it. Include a command that uses GNU Parallel if you feel like it.
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.
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.
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.
For example you can run this to convert all jpeg files into png and gif files and have a progress bar:
parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif
Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:
find . -name '*.jpg' |
parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200
You can find more about GNU Parallel at: http://www.gnu.org/s/parallel/

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.
The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.

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.

Dear community
GNU Health Hospital Management 4.4.1 has been released!
Priority: High
We provide "patchsets" to stable releases. Patchsets allow applying bug fixes and updates on production systems. Always try to keep your production system up-to-date with the latest patches.
Patches and Patchsets maximize uptime for production systems, and keep your system updated, without the need to do a whole installation.
NOTE: Patchsets are applied on previously installed systems only. For new, fresh installations, download and install the whole tarball (ie, gnuhealth-4.4.1.tar.gz)
You can do automatic updates on the GNU Health HMIS kernel and modules using the GNU Health control center program.
Please refer to the administration manual section ( https://docs.gnuhealth.org/his/techguide/administration/controlcenter.html )
The GNU Health control center works on standard installations (those done following the installation manual on wikibooks). Don't use it if you use an alternative method or if your distribution does not follow the GNU Health packaging guidelines.
You must apply previous patchsets before installing this patchset. If your patchset level is 4.4.0, then just follow the general instructions. You can find the patchsets at GNU Health main download site at GNU.org (https://ftp.gnu.org/gnu/health/)
In most cases, GNU Health Control center (gnuhealth-control) takes care of applying the patches for you.
Pre-requisites for upgrade to 4.4.1: None
Now follow the general instructions at
https://docs.gnuhealth.org/his/techguide/administration/controlcenter.html
After applying the patches, make a full update of your GNU Health database as explained in the documentation.
When running "gnuhealth-control" for the first time, you will see the following message: "Please restart now the update with the new control center" Please do so. Restart the process and the update will continue.

Libtoolers!
The Libtool Team is pleased to announce the release of libtool 2.5.1, a beta release.
GNU Libtool hides the complexity of using shared libraries behind a
consistent, portable interface. GNU Libtool ships with GNU libltdl, which
hides the complexity of loading dynamic runtime libraries (modules)
behind a consistent, portable interface.
There have been 33 commits by 8 people in the 10 weeks since 2.5.0.
See the NEWS below for a brief summary.
Thanks to everyone who has contributed!

Do you need a thread-safe atomic counter in Python? Use itertools.count():
>>> from itertools import count >>> counter = count() >>> next(counter) 0 >>> next(counter) 1 >>> next(counter) 2
I found this in the decorator package, labelled Atomic get-and-increment provided by the GIL
. So simple! So cool!

Guix is the fruit of a combination of volunteer work by an amazing number of people, work paid for by employers, but also work sponsored by public institutions. The European Commission’s Next Generation Internet (NGI) calls have been instrumental in that regard. News that NGI funding could vanish came to us as a warning signal.
Since 2020, NGI has supported many free software projects, allowing for significant strides on important topics that would otherwise be hard to fund. As an example, here are some of the NGI grants that directly benefited Guix and related projects:
Over the years, NGI has more than demonstrated that public financial support for free software development makes a difference. We strongly believe that this support must continue, that it must strengthen the development of innovative software where user autonomy and freedom is a central aspect.
For these reasons, the Guix project joins a growing number of projects and organizations in signing the following open letter to the European Commission.
The open letter below was initially published by petites singularités. English translation provided by OW2.
Since 2020, Next Generation Internet (NGI) programmes, part of European Commission's Horizon programme, fund free software in Europe using a cascade funding mechanism (see for example NLnet's calls). This year, according to the Horizon Europe working draft detailing funding programmes for 2025, we notice that Next Generation Internet is not mentioned any more as part of Cluster 4.
NGI programmes have shown their strength and importance to supporting the European software infrastructure, as a generic funding instrument to fund digital commons and ensure their long-term sustainability. We find this transformation incomprehensible, moreover when NGI has proven efficient and economical to support free software as a whole, from the smallest to the most established initiatives. This ecosystem diversity backs the strength of European technological innovation, and maintaining the NGI initiative to provide structural support to software projects at the heart of worldwide innovation is key to enforce the sovereignty of a European infrastructure. Contrary to common perception, technical innovations often originate from European rather than North American programming communities, and are mostly initiated by small-scaled organisations.
Previous Cluster 4 allocated 27 million euros to:
In the name of these challenges, more than 500 projects received NGI funding in the first 5 years, backed by 18 organisations managing these European funding consortia.
NGI contributes to a vast ecosystem, as most of its budget is allocated to fund third parties by the means of open calls, to structure commons that cover the whole Internet scope - from hardware to application, operating systems, digital identities or data traffic supervision. This third-party funding is not renewed in the current program, leaving many projects short on resources for research and innovation in Europe.
Moreover, NGI allows exchanges and collaborations across all the Euro zone countries as well as "widening countries"¹, currently both a success and an ongoing progress, likewise the Erasmus programme before us. NGI also contributes to opening and supporting longer relationships than strict project funding does. It encourages implementing projects funded as pilots, backing collaboration, identification and reuse of common elements across projects, interoperability in identification systems and beyond, and setting up development models that mix diverse scales and types of European funding schemes.
While the USA, China or Russia deploy huge public and private resources to develop software and infrastructure that massively capture private consumer data, the EU can't afford this renunciation. Free and open source software, as supported by NGI since 2020, is by design the opposite of potential vectors for foreign interference. It lets us keep our data local and favors a community-wide economy and know-how, while allowing an international collaboration.
This is all the more essential in the current geopolitical context: the challenge of technological sovereignty is central, and free software allows to address it while acting for peace and sovereignty in the digital world as a whole.
In this perspective, we urge you to claim for preserving the NGI programme as part of the 2025 funding programme.
¹ As defined by Horizon Europe, widening Member States are Bulgaria, Croatia, Cyprus, Czechia, Estonia, Greece, Hungary, Latvia, Lituania, Malta, Poland, Portugal, Romania, Slovakia, and Slovenia. Widening associated countries (under condition of an association agreement) include Albania, Armenia, Bosnia, Feroe Islands, Georgia, Kosovo, Moldavia, Montenegro, Morocco, North Macedonia, Serbia, Tunisia, Turkeye, and Ukraine. Widening overseas regions are Guadeloupe, French Guyana, Martinique, Reunion Island, Mayotte, Saint-Martin, The Azores, Madeira, the Canary Islands.

The GNU C Library
=================
The GNU C Library version 2.40 is now available.
The GNU C Library is used as the C library in the GNU system and
in GNU/Linux systems, as well as many other systems that use Linux
as the kernel.
The GNU C Library is primarily designed to be a portable
and high performance C library. It follows all relevant
standards including ISO C11 and POSIX.1-2017. It is also
internationalized and has one of the most complete
internationalization interfaces known.
The GNU C Library webpage is at http://www.gnu.org/software/libc/
Packages for the 2.40 release may be downloaded from:
http://ftpmirror.gnu.org/libc/
http://ftp.gnu.org/gnu/libc/
The mirror list is at http://www.gnu.org/order/ftp.html
Distributions are encouraged to track the release/* branches
corresponding to the releases they are using. The release
branches will be updated with conservative bug fixes and new
features while retaining backwards compatibility.
NEWS for version 2.40
=====================
Major new features:

in order to support unsigned __int128 and/or unsigned _BitInt(N) operands
with arbitrary precisions when supported by the target.
enable features from the ISO C23 standard. Only some features from
this standard are supported by the GNU C Library. The older name
_ISOC2X_SOURCE is still supported. Features from C23 are also enabled
by _GNU_SOURCE, or by compiling with the GCC options -std=c23,
-std=gnu23, -std=c2x or -std=gnu2x.

functions for float, double, long double, _FloatN and _FloatNx, and a
type-generic macro in <tgmath.h>.
- Exponential functions: exp2m1, exp10m1.
- Logarithmic functions: log2p1, log10p1, logp1.

Deprecated and removed features, and other changes affecting compatibility:
lastlog, struct utmp, struct utmpx (such as i386, powerpc64le, rv32,
rv64, x86-64) switched from a signed to an unsigned type for that
field. This allows these fields to store timestamps beyond the year
2038, until the year 2106. Please note that applications are still
expected to migrate off the interfaces declared in <utmp.h> and
<utmpx.h> (except for login_tty) due to locking and session management
problems.

GNU Parallel 20240722 ('Assange') has been released. It is available for download at: lbry://@GnuParallel:4
Quote of the month:
parallel is frickin great for launching jobs on multiple
machines. Ansible and Jenkins and others may be good too but I was
able to jump right in with parallel.

News about GNU Parallel:
GNU Parallel - For people who live life in the parallel lane.
If you like GNU Parallel record a video testimonial: Say who you are, what you use GNU Parallel for, how it helps you, and what you like most about it. Include a command that uses GNU Parallel if you feel like it.
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.
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.
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.
For example you can run this to convert all jpeg files into png and gif files and have a progress bar:
parallel --bar convert {1} {1.}.{2} ::: *.jpg ::: png gif
Or you can generate big, medium, and small thumbnails of all jpeg files in sub dirs:
find . -name '*.jpg' |
parallel convert -geometry {2} {1} {1//}/thumb{2}_{1/} :::: - ::: 50 100 200
You can find more about GNU Parallel at: http://www.gnu.org/s/parallel/
You can install GNU Parallel in just 10 seconds with:
$ (wget -O - pi.dk/3 || lynx -source pi.dk/3 || curl pi.dk/3/ || \
fetch -o - http://pi.dk/3 ) > install.sh

If GNU Parallel saves you money:
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.
The database is addressed using a DBURL. If commands are left out you will get that database's interactive shell.
When using GNU SQL for a publication please cite:
O. Tange (2011): GNU SQL - A Command Line Tool for Accessing Different Databases Using DBURLs, ;login: The USENIX Magazine, April 2011:29-32.
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.

We are happy to announce the completion of milestone 5 for the DHT specification. The general objective is to provide a detailed and comprehensive guide for implementors of the GNUnet DHT "R 5 N". As part of this milestone, the specification was updated and interoperability testing conducted. We submitted the draft to the Independent Stream Editor (ISE) who is going to decide if it will be adopted and shepherded through the RFC process.
The current protocol is implemented as part of GNUnet and gnunet-go as announced on the mailing list when the previous implementation milestones were finished .
We again invite any interested party to read the document and provide critical review and feedback. This greatly helps us to improve the protocol and help future implementations. Contact us at the gnunet-developers mailing list .
This work is generously funded by NLnet as part of their NGI Assure fund .
Dear community
I am happy to announce patchset 2.2.1 for MYGNUHealth, the GNU Health Personal Health Record.
This patchset fixes the following issues:
You can download MyGNUHealth source code from the official GNU Savannah (https://ftp.gnu.org/gnu/health/mygnuhealth/). You can also install MyGH from the Python Package Index (PyPI) or from your operating system distribution.
Happy hacking
Luis

When I opened this Savannah project I imported items from the old GNU tasklist document. 20 years later all of the context has been lost (if there ever was any) so now if anyone asks about these tasks it just leads to frustration on everyone's part.
I therefore deleted the original help wanted entries that date back to 2003. If anyone wants to help the GNU project, the best way to do that is to pick one of the FSF's High-Priority projects:
