+<h3 id="aris"><a href="https://www.gnu.org/software/aris";>GNU Aris</a></h3>
+
+<p>
+ GNU Aris is a logical proof program that supports propositional and
+ predicate logic, as well as Boolean algebra and arithmetical logic,
+ in the form of abstract sequences.
+</p>
+
+<ul>

+ </li>
+</ul>
+
+<h4>Add a web user interface to GNU Aris</h4>
+
+<p>
+ GNU Aris can be successfully used in explaining some basic concepts
+ of propositional and predicate logic. Its user interface is based on
+ GTK which prevents usage on certain platforms. By targeting the web
+ platform, end users could have the opportunity to access a unified
+ interface. This could be a great step in teaching and learning
+ concepts in logic.
+</p>
+
+<ul>
+ <li><strong>Required skills:</strong> C programming, basic knowledge of
+ WebAssembly, emscripten, HTML.
+ </li>

+
+<img align="right" width="160"
src="https://www.gnunet.org/images/gnunet-logo-dark-no-text.png"; />
+
+<p>
+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.
+</p>
+
+<p>GNUnet maintains a list of ideas here:
+ <a
href="https://stage.gnunet.org/en/gsoc.html";>https://stage.gnunet.org/en/gsoc.html</a>.</p>
+
+<h3 id="hurd"><a href="https://www.gnu.org/software/hurd";>GNU Hurd</a></h3>
+
+<img align="right" width="160"
src="https://www.gnu.org/graphics/hurd_sm_mf.png"; />
+
+<p>
+The GNU Hurd is the GNU project's replacement for the Unix kernel. It
+is a collection of servers that run on the Mach microkernel to
+implement file systems, network protocols, file access control, and
+other features that are implemented by the Unix kernel or similar
+kernels (such as Linux).
+</p>
+

+ </li>
+</ul>
+
+<h4>Porting Rust to GNU/Hurd</h4>
+
+<p>
+ The goal of this project is to make the Rust language
+ (<a href="https://www.rust-lang.org/";>https://www.rust-lang.org/</a>)
+ available on GNU/Hurd.
+</p>
+<p>
+ The Rust language is being used more and more widely, and notably in
+ rather fundamental libraries such as librsvg or
+ python-cryptography. It is thus more and more pressing for GNU/Hurd
+ to have a compiler for Rust.
+</p>
+<p>
+ The Rust compiler itself is quite portable, but its runtime library,
+ libstd, needs to be ported to the GNU/Hurd system. This essentially
+ consists in telling Rust how the standard C library functions can be
+ called.
+</p>
+<p>
+ And example of the main part of such port can be seen for the
+ VxWorks port:
+ <a
href="https://github.com/rust-lang/libc/blob/master/src/vxworks/mod.rs";>https://github.com/rust-lang/libc/blob/master/src/vxworks/mod.rs</a>
+</p>
+<p>
+ The bulk of such a file can be mostly generated from the libc C
+ headers thanks to the bindgen tool, it then needs to be cleaned up
+ and integrated into the Rust build infrastructure, some preliminary
+ work had already been investigated in that part.
+</p>
+<p>
+ A cross-bootstrap from Linux will then need to be achieved to build
+ rustc and cargo, and then it will be self-hosted on GNU/Hurd.
+</p>
+
+<ul>
+ <li><strong>Required skills:</strong> A good level of C programming
+will be welcome to understand the questions of ABI and the libc C
+functions being bound. Knowing the Rust language is not required: it
+can be learnt along the way, this can be a good occasion.

+<h3 id="cobol"><a
href="https://www.gnu.org/software/gnucobol";>GnuCOBOL</a></h3>
+
+<p>
+GnuCOBOL is a free, modern COBOL compiler. It implements a substantial
+part of the COBOL 85, X/Open COBOL and newer ISO COBOL standards
+(2002, 2014, 2023), as well as many extensions included in other COBOL
+compilers (IBM COBOL, MicroFocus COBOL, ACUCOBOL-GT and others).
+</p>
+<p>
+GnuCOBOL translates COBOL into C and internally compiles the
+translated code using a native C compiler, therefore works on nearly
+every platform.

+<h4>Add a web user interface to XaoS</h4>
+
+<p>
+ XaoS has a Qt interface, but to use it, end users require to
+ download and install the software. This is not always possible,
+ which is most problematic in schools and classrooms. The Qt system
+ allows compiling the code into a HTML/JavaScript/WebAssembly
+ application, however, the current version of XaoS is malfunctioning
+ on the web platform because of a non-conform way of the
+ implementation of realtime animation. In this project a fully
+ working web application is to be implemented.

+<h3 id="guix"><a href="https://www.gnu.org/software/guix";>GNU Guix</a></h3>
+
+<p>
+ GNU Guix is the GNU package manager.
+
+ GNU Guix provides state-of-the-art package management features such
+ as transactional upgrades and roll-backs, reproducible build
+ environments, unprivileged package management, and per-user
+ profiles. It uses low-level mechanisms from the Nix package manager,
+ but packages are defined as native Guile modules, using extensions
+ to the Scheme languageâwhich makes it nicely hackable.
+</p>
+<p>
+ It maintains their list of ideas for GSOC in an external
+ webpage:

+
+<h3 id="mes"><a href="">GNU Mes</a></h3>
+
+<p>
+ GNU Mes is a Scheme interpreter and C compiler for bootstrapping the
+ GNU System. Since version 0.22 it has again helped to halve the size
+ of opaque, uninspectable binary seeds that are currently being used
+ in the Reduced Binary Seed bootstrap of GNU Guix. The final goal is
+ to help create a full source bootstrap as part of the bootstrappable
+ builds effort for UNIX-like operating systems.

+
+<h3 id="xaos"><a href="https://www.gnu.org/software/xaos";>XaoS</a></h3>
+
+<p>
+GNU XaoS is an interactive fractal zoomer. It allows the user to
+continuously zoom in or out of a fractal in a fluid, continuous
+motion. This capability makes XaoS great for exploring fractals, and
+it's fun!
+</p>
+
+<h4>Turning XaoS into a web application</h4>
+
+<p>
+ GNU XaoS is a popular real-time fractal zoomer and morpher. Its
+ version 4.0 is available since April 2020---it provides a new user
+ interface based on Qt. Qt allows applications to be compiled to run
+ in a web browser, however, some requirements must be met. See
+ <a href="https://github.com/xaos-project/XaoS/issues/151";>this</a>
+ for more information. In this project the task is to find the
+ affected parts of XaoS and change them to be able to compile for
+ running in a browser.
+</p>
+
+<h3 id="gnuastro"><a href="https://www.gnu.org/software/gnuastro";>GNU
+ Astronomy Utilities</a></h3>
+
+<p>
+ GNU Astronomy Utilities (Gnuastro) is an official GNU package consisting of
<a
href="https://www.gnu.org/software/gnuastro/manual/html_node/Gnuastro-programs-list.html";>various
programs</a> and <a
href="https://www.gnu.org/software/gnuastro/manual/html_node/Gnuastro-library.html";>library
functions</a> for the manipulation and analysis of (astronomical) data.
+ All the programs share the same basic command-line user interface for the
comfort of both the users and developers, some <a
href="https://www.gnu.org/software/gnuastro/manual/html_node/Tutorials.html";>complete
tutorials</a> are available to help getting started or obtaining a general
view.
+ Gnuastro is written to comply fully with the GNU coding standards so it
integrates finely with the GNU/Linux operating system.
+ This also enables astronomers to expect a fully familiar experience in the
source code, building, installing and command-line user interaction that they
have seen in all the other GNU software that they use.
+</p>
+
+<p>
+ Gnuastro's proposed projects for this summer-of-code are listed below.
+ More generally, you can also see the full list of <a
href="http://savannah.gnu.org/task/?group=gnuastro";>open tasks</a> and <a
href="https://savannah.gnu.org/bugs/?group=gnuastro";>open bugs</a> (for all
programs/libraries) and suggest a different project for us to consider.
+ The preferred way to get in touch is through Gnuastro's "Support tracker" on
Savannah and in particular <a
href="https://savannah.gnu.org/support/?110195";>sr #110195</a>.
+ You can also see previous discussions there on tips for getting started.
+ In case you need to have private discussions, you can also contact the given
email.
+</p>
+
+
+<h4>Improving Image Processing tools in GNU Astronomy Utilities</h4>
+
+<p>
+ Gnuastro's programs already contain many image processing tools for
professional (research quality) usage.
+ However, there are still many tools that remain to be added are are
necessary for a complete workflow.
+ For example image registration (finding the warp necessary to match images),
non-linear warping (for example correcting optical distortions or gravitational
lensing) or de-blending tools (for example to separate galaxies that are in one
line of sight).
+ If you are interested in image processing, programming in C (astronomical
datasets are large and thus need to be efficient) and in the meantime learning
some astronomy and working with major telescope data, please get in touch.
+</p>
+
+<p>
+ <strong>Required Skills</strong>: C programming, basic knowledge of image
processing concepts.
+ <br />
+ <strong>Contact</strong>: <a

mohammad::at::akhlaghi.org.
+</p>
+
+<h4>Python/R/Julia API for GNU Astronomy Utilities C library</h4>
+
+<p>
+ Gnuastro is primarily written in C because astronomical datasets are large
and thus need to be efficient.
+ Its most commonly used interface are its <a
href="https://www.gnu.org/software/gnuastro/manual/html_node/Gnuastro-programs-list.html";>command-line
programs</a>, but it also has an extensive set of installed <a
href="https://www.gnu.org/software/gnuastro/manual/html_node/Gnuastro-library.html";>C/C++
libraries</a>, which the programs also use.
+ However, many data science operations are today done in the high-level
language environments of Python, R or Julia.
+ All three languages have low-level and well-defined interfaces for
communicating with installed C libraries.
+ Gnuastro therefore has <a href="http://savannah.gnu.org/task/?13786";>a
task</a> to define a low-level wrapper infra-structure which will allow easy
usage in these higher-level languages also.
+ We welcome anyone interested in managing this task for one of these
languages as part of GSoC.
+ This will be a wonderful chance to master any of these high-level languages
(which are almost fully written in C themselves), while also working on
real-world data science/analysis.
+</p>
+
+<p>
+ <strong>Skills required</strong>: C programming, C interface of Python or R
or Julia (whichever you are better at!).

+<h3 id="cobol"><a href="http://www.gnu.org/s/gnucobol";>GnuCOBOL</a></h3>
+
+<p>
+GnuCOBOL is a free software COBOL compiler. cobc translates COBOL
+source code to native executable using intermediate C, designated C
+compiler and linker.
+</p>
+
+<h4>Eclipse plugin for use with GnuCOBOL</h4>
+
+<p>
+ Many developers use Eclipse as their IDE. The possibility to use
+ its framework and plugin ecosystem is one of the reasons for this
+ and different proprietary COBOL implementations therefore provided
+ COBOL plugins. Despite of normally being proprietary and "only-for
+ customers-with-a-license" they are very tight coupled to their
+ "products".
+</p>
+<p>
+ This project is about creating a plugin for GnuCOBOL featuring:
+</p>
+<ul>
+ <li>COBOL compiler setup (used for compilation, running and
+ syntax-check)</li>
+ <li>COBOL project (pre-defined settings, compilation of outdated parts)</li>
+ <li>COBOL editor with syntax highlighting and code outline;
+ ideally supporting both fixed-form (column-based) and free-form
+ reference-format</li>
+ <li>ideally: support for refactoring</li>
+ <li>ideally: support for external pre-parsers with additional reserved
+ words and/or blocks</li>
+ <li>optional: code content assist</li>
+ <li>optional: code templates</li>
+ <li>optional: program templates</li>
+</ul>
+
+<p>
+ <strong>Skills required:</strong> Knowledge of Java, ideally
+ knowledge of the Eclipse plugin system. Knowledge of COBOL and
+ possibly the GnuCOBOL package is welcome but not mandatory.

+
+<h4>Extension of screenio interface (curses based)</h4>
+
+<p>
+ GnuCOBOL uses curses (ncurses/pdcurses) to create a portable
+ "extended" screenio.
+</p>
+<p>
+ This project is about extending the runtime parts handling this.
+</p>
+<ul>
+ <li>add support to use curses windows</li>
+ <li>improve handling to accept formatted and numeric values</li>
+ <li>save and restore screen attributes and data</li>

+ Astronomy Utilities</a></h3>
+
+<p>
+ GNU Astronomy Utilities (Gnuastro) is an official GNU package consisting of
<a
href="https://www.gnu.org/software/gnuastro/manual/html_node/Gnuastro-programs-list.html";>various
programs</a> and <a
href="https://www.gnu.org/software/gnuastro/manual/html_node/Gnuastro-library.html";>library
functions</a> for the manipulation and analysis of (astronomical) data.
+ All the programs share the same basic command-line user interface for the
comfort of both the users and developers, some <a
href="https://www.gnu.org/software/gnuastro/manual/html_node/Tutorials.html";>complete
tutorials</a> are available to help getting started or obtaining a general
view.
+ Gnuastro is written to comply fully with the GNU coding standards so it
integrates finely with the GNU/Linux operating system.
+ This also enables astronomers to expect a fully familiar experience in the
source code, building, installing and command-line user interaction that they
have seen in all the other GNU software that they use.
+</p>
+
+<p>
+ Gnuastro's proposed projects for this summer-of-code are listed below.
+ More generally, you can also see the full list of <a
href="http://savannah.gnu.org/task/?group=gnuastro";>open tasks</a> and <a
href="https://savannah.gnu.org/bugs/?group=gnuastro";>open bugs</a> (for all
programs/libraries) and suggest a different project for us to consider.
+ The preferred way to get in touch is through Gnuastro's "Support tracker" on
Savannah and in particular <a
href="https://savannah.gnu.org/support/?110195";>sr #110195</a>.
+ You can also see previous discussions there on tips for getting started.
+ In case you need to have private discussions, you can also contact the given
email.

+
+<h4>Improving Image Processing tools in GNU Astronomy Utilities</h4>
+
+<p>
+ Gnuastro's programs already contain many image processing tools for
professional (research quality) usage.
+ However, there are still many tools that remain to be added are are
necessary for a complete workflow.
+ For example image registration (finding the warp necessary to match images),
non-linear warping (for example correcting optical distortions or gravitational
lensing) or de-blending tools (for example to separate galaxies that are in one
line of sight).
+ If you are interested in image processing, programming in C (astronomical
datasets are large and thus need to be efficient) and in the meantime learning
some astronomy and working with major telescope data, please get in touch.
+</p>
+
+<p>
+ <strong>Required Skills</strong>: C programming, basic knowledge of image
processing concepts.

+</p>
+
+<h4>Python/R/Julia API for GNU Astronomy Utilities C library</h4>
+
+<p>
+ Gnuastro is primarily written in C because astronomical datasets are large
and thus need to be efficient.
+ Its most commonly used interface are its <a
href="https://www.gnu.org/software/gnuastro/manual/html_node/Gnuastro-programs-list.html";>command-line
programs</a>, but it also has an extensive set of installed <a
href="https://www.gnu.org/software/gnuastro/manual/html_node/Gnuastro-library.html";>C/C++
libraries</a>, which the programs also use.
+ However, many data science operations are today done in the high-level
language environments of Python, R or Julia.
+ All three languages have low-level and well-defined interfaces for
communicating with installed C libraries.
+ Gnuastro therefore has <a href="http://savannah.gnu.org/task/?13786";>a
task</a> to define a low-level wrapper infra-structure which will allow easy
usage in these higher-level languages also.
+ We welcome anyone interested in managing this task for one of these
languages as part of GSoC.
+ This will be a wonderful chance to master any of these high-level languages
(which are almost fully written in C themselves), while also working on
real-world data science/analysis.
+</p>
+
+<p>
+ <strong>Skills required</strong>: C programming, C interface of Python or R
or Julia (whichever you are better at!).

+
+<p>
+ GNU Guix is the GNU package manager.
+
+ GNU Guix provides state-of-the-art package management features such
+ as transactional upgrades and roll-backs, reproducible build
+ environments, unprivileged package management, and per-user
+ profiles. It uses low-level mechanisms from the Nix package manager,
+ but packages are defined as native Guile modules, using extensions
+ to the Scheme languageâwhich makes it nicely hackable.

+
+<h4>Enhance export to support high quality output</h4>
+
+<p>
+ Render very large size images as TIFF files to print artworks as
+ e.g. 1 x 2 metre 400 dpi CPrints. Wide colour gamut e.g. ProFoto and
+ Adobe1998 colour profiles. Cropping/in-proportion sizing. Batch
+ output using previous files in native XaoS format. As an example
+ please see the output option in e.g. Capture One Pro.
+</p>
+<p>
+ <strong>Required skills:</strong> Good knowledge of C++ programming.
+ <br/>
+ <strong>Contact address:</strong> zoltan@geogebra.org.
+</p>
+
+<h4>Support for arbitrary precision</h4>
+
+<p>
+XaoS currently cannot support very deep zooms because the 80-bit floating
+point arithmetic used runs out of precision before too long. It should be
+possible to add arbitrary precision to XaoS using the MPFR library (
+https://www.mpfr.org/), or a different one if it is not fast enough to
+support real-time zooming. See also
+https://github.com/xaos-project/XaoS/issues/24, in particular

+<h3 id="emacs"><a href="http://www.gnu.org/s/emacs";>GNU Emacs</a></h3>
+
+<h4>Improving Traceback Information in ELisp Bytecode</h4>
+
+<p>The GNU Emacs Lisp Bytecode interpreter plays an important role in GNU
+ Emacs, possibly moreso than say javascript is to Firefox. The bytecode
+ compilation system and runtime system which go back to the earliest
+ days of Emacs could use improvement.
+</p>
+
+<p>
+Currently, when there is an error in bytecode, the bytecode offset
+where the error occurs is not recorded. Currently this information is
+in a register containing a memory pointer rather than a usable
+bytecode offset.
+</p>
+
+<p>
+ Therefore, the first task would be to get the bytecode offset make that
+ available and added to the call stack.
+</p>
+<p>
+ After this, there are several possibilities for turning the
+ offset back into a source-code location, or failing that,
+ displaying the location next to a disassembly of the bytecode.
+ Getting a source-code location from a bytecode object will most
+ likely involve chainge the bytecode compiler to save this
+ information and there are several possibilites here.
