The International Neuroinformatics Coordinating Facility (INCF; www.incf.org) is an international organization launched in 2005, following a proposal from the Global Science Forum of the OECD.

INCF was established to facilitate and promote the sharing of data and computing resources in the international neuroscience community. A larger objective of INCF is to help develop scalable, portable, and extensible applications that can be used by neuroscience laboratories worldwide.

The mission of INCF is to make neuroscience FAIR (Findable, Accessible, Interoperable and Reusable) by sharing and integrating neuroscience data and knowledge worldwide. We foster scientific community collaboration to develop standards for data sharing, analysis modeling and simulation in order to catalyze insights into brain function in health and disease.

INCF activities are open to all who can contribute to neuroinformatics at the international level. We have a global community of neuroscience researchers working on new and improved tools for all of neuroscience – enabling other researchers to make more and faster discoveries, and improving our understanding of the brain.

Haiku is a fast, efficient, easy to use and lean open source operating system inspired by the BeOS that specifically targets personal computing.

Haiku is not a Linux distribution, nor does it use the Linux kernel. Haiku is the spiritual successor to BeOS and it is derived from the NewOS kernel, which was authored by Travis Geiselbrecht (geist), who was formerly employed by Be Inc. — the developers of BeOS.

Linux-based distributions stack up software – the Linux kernel, the X Window System, and various DEs with disparate toolkits such as GTK+ and Qt – that do not necessarily share the same guidelines and/or goals. This lack of consistency and overall vision manifests itself in increased complexity, insufficient integration, and inefficient solutions, making the use of your computer more complicated than it should actually be.

Instead, Haiku has a single focus on personal computing and is driven by a unified vision for the whole OS. That, we believe, enables Haiku to provide a leaner, cleaner and more efficient system capable of providing a better user experience that is simple and uniform throughout.

MuseScore can play back scores through a sequencer and SoundFont sample library. Playback is currently being greatly expanded to include VST support. MIDI output to external devices and software synthesisers is also possible.

The team organise themselves according to a general roadmap published by the product owner every six months, which sets out provisional goals for the internal team. This allows the extended developer community to comment on the roadmap and potentially offer to take ownership over aspects of it. This also allows other contributors to have visibility on aspects of the codebase that may change over the next 6-12 months. In combination with our community organiser, tasks are drawn up and published to provide a well organised collaboration focused on a specific upcoming release.

All members provide bug tracking support and feedback.

GeomScale is a research and development project that delivers open source code for state-of-the-art algorithms at the intersection of data science, optimization, geometric, and statistical computing. The current focus of GeomScale is on scalable algorithms for sampling from high-dimensional distributions, integration, convex optimization, and their applications. One of our ambitions is to fill the gap between theory and practice by turning state-of-the-art theoretical tools in geometry and optimization to state-of-the-art implementations. Towards this goal, we will deliver various innovative solutions in a variety of application fields, like finance, computational biology, and statistics that will extend the limits of contemporary computational tools. GeomScale aims in serving as a building block for an international, interdisciplinary, and open community in high dimensional geometrical and statistical computing. The main development is currently performed in volesti, a generic open source C++ library, with R and python interfaces (the latter is hosted in package dingo), for high-dimensional sampling, volume approximation, and copula estimation for financial modelling. In particular, the current implementation scales up to hundred or thousand dimensions, depending on the problem. To our knowledge it is the most efficient software package for sampling and volume computation to date. It is, in several cases, orders of magnitude faster compared to packages that solve the same problems. It can be used to compute challenging multivariate integrals and to approximate optimal solutions in optimization problems. It has already found important applications in systems biology by analyzing large metabolic networks (e.g., the latest human network) and in FinTech by detecting shock events and by evaluating portfolios performance in stock markets with thousands of assets. Other application areas include AI and in particular approximate weighted model integration.

Mathematicians, scientists, researchers, and students need a powerful tool for their work or study. SageMath is a freely available open-source mathematical software system bundling the functionality of many software libraries, exposing their features in a common interface and extending on top of this with its own powerful algorithms. By leveraging the flexibility and universality of the underlying Python interpreter, SageMath is able to accommodate for a vast range of their requirements.

The mission of SageMath is to create a viable open-source alternative to all major proprietary mathematical software systems.

Python is the main programming language inside the SageMath library and also the language of choice for all interactions with the built-in objects and functions for expressing mathematical concepts and calculations. Besides a command-line and programming-library interface, its primary user interface is a dynamic self-hosted website. From the perspective of a user, the interface language is Python, but with a thin extension built directly on top of it.

Almost all areas of mathematics are represented in SageMath, at various levels of sophistication. This includes symbolic calculus, 2D and 3D graphics, polynomials, graph theory, group theory, abstract algebra, combinatorics, cryptography, elliptic curves and modular forms, numerical mathematics, linear algebra and matrix calculations (over various rings), support for parallel computing, and a powerful coercion framework to “mix” elements from different sets for calculations. SageMath’s features also expand into neighboring fields like Statistics and Physics.

Mass spectrometry is an analytical technique that measures the mass and abundance of small molecules with very high precision. However, the datasets produced by mass spectrometry instruments are complex and multi-dimensional. MZmine (https://mzmine.org; implemented in Java and JavaFX) and MS-DIAL (http://prime.psc.riken.jp/compms/msdial/main.html; implemented in C#) are popular open-source graphical software tools for mass spectrometry data processing. Both contain a library of processing algorithms and powerful visualization modules.

Both MZmine and MS-DIAL are highly cited (>4500 cumulated citations in Pluskal et al., BMC Bioinformatics 2010 and Tsugawa et al., Nature Methods 2015) demonstrating the impact the software tools have in the biomedical research community.

MZmine 3 is based on JavaFX for its user interface and provides support for cutting-edge techniques such as ion mobility separation. We aim to provide user-friendly, flexible, and extendable modular software covering the entire mass spectrometry data analysis workflow.

MS-DIAL 5 follows the mind of MZmine, and the program is written by C# and WPF. As the unique functions, the program supports the chromatogram deconvolution for data independent acquisition. Furthermore, MS-DIAL 5 also supports the annotation function for various mass fragmentation techniques, mass spectrometry imaging, and proteomics, resulting in the environment for multiomics analysis.

MZmine successfully participated in Google Summer of Code in the years 2017, 2018, and 2019 under the OpenChemistry umbrella, and in 2020 and 2022 as its own organization. Now both MZmine and MS-DIAL projects team up for GSoC 2023.

The X.Org Foundation (or X.Org for short) is a foundation chartered to develop and execute effective strategies that provide worldwide stewardship and encouragement of the X Window System and related projects. Indeed, X.Org is much broader than just the X Window System. Under the umbrella of the X.Org Foundation can be found Linux's DRM subsystem (10% of the size of Linux), Mesa (open source 3D and video-decoding acceleration for AMD, Intel, NVIDIA,...), and Wayland. X.org's technologies underpin much of today's computing environment, and expertise in it is in high demand worldwide.

Today, as the result of more than 20 years of work by teams of leading open source developers, most of the graphical user interfaces for Unix and Linux systems rely on X.Org. On top of the X-Server-based systems, this includes Android- and ChromeOS-based devices, and Wayland-based systems (Sailfish OS, Gnome, ...). X.Org is responsible for the design of the X libraries which interface with application, the acceleration architectures used for graphics, and the graphics and input drivers. In particular, it has been at the center of the recent restructuring of the Linux graphics driver stack.

Come help us make the future more open!

The UC Open Source Program Office (OSPO) supports open source work throughout the University of California system. Beginning in 2022, the UC OSPO took over the programmatic responsibilities of the UCSC Center for Research in Open Source Software (CROSS), including mentorship activities such as GSoC. Following in line with the earlier work of CROSS, the OSPO creates partnerships with stakeholders within and outside the UC system in order to help students learn from open source communities, support scientists in using open source to accelerate research efforts, and connect students and scientists with sponsors from industry, government, and foundations. The OSPO helps bridge the gap between academic research and successful open source projects by promoting innovative projects maintained by UC-affiliated scientists and researchers. We support the transfer of cutting-edge technology resulting from UC-originating research to industry via successful open source projects. Due to the multi-campus nature of our current efforts, the projects we support and promote cover a wide range of topics and technologies - including:

• Open Source Hardware
• Storage Systems and Devices
• System Architecture
• Autonomous Vehicle Systems
• Data Management
• Data Analysis
• Visualization
• Reproducibility

All of our mentors are UC-affiliated scientists and researchers who are actively involved in one or more of these open source projects.

The MetaBrainz Foundation is a non-profit that believes in free, open access to data. It has been set up to build community maintained databases and make them available in the public domain or under Creative Commons licenses.

Our data is mostly gathered by volunteers and verified by peer review to ensure it is consistent and correct. All non-commercial use of this data is free, but commercial users are asked to support us in order to help fund the project. We encourage all data users to contribute to the data gathering process so that our data can be as comprehensive as possible.

With this data we are building a music social network and bias free music recommendations.

The Palisadoes Foundation’s open-source software projects support community groups in organizing their daily activities. A significant proportion of our software contributions come from university students studying software engineering. Participants often come from under-served communities or geographic areas and are sponsored through our various programs. This prepares them for the competitive realities of the working world.

Life started for us in 2016 when a group of expatriate Jamaicans wanted to assist development of new and existing information technologies for the island’s social good. We knew academic and student leadership wanted greater practical exposure to the latest technology. In response, our pilot Calico program for Jamaican universities was created with the goal of addressing the issues graduates would face when employed.

After five years of success, members of the Jamaican diaspora suggested we expand our service area to be global. They saw similar needs in their own under-served communities where the digital divide is very visible and thought our experience in the developing world would be useful.

Since 2019 we have focused on creating a mobile app to help community organizations like ourselves better manage their membership. We saw the need for a social media component to keep in contact with our volunteers. We also felt these organizations often faced challenges with the project management of events and keeping track of volunteer abilities, roles and responsibilities.

We want to make the app useful for any community-based organization such as clubs, small religious institutions, neighborhood groups, and volunteer associations. We also want to see how the open source software could be installed as a multi-tenant, multi-site cloud hosted service as many of these organizations often don’t have sufficient IT skills to do so independently. We hope that our contributors will help us achieve this goal year.

Are you interested in contributing to a widely-used performance evaluation tool for computer networking research? ns-3 is a discrete-event, packet-level network simulator with an emphasis on networking research and education. Users of ns-3 can construct simulations of computer networks using models of traffic generators, protocols such as TCP/IP, and devices and channels such as Wi-Fi and LTE, and analyze or visualize the results. Simulation plays a vital role in the research and education process, because of the ability for simulations to obtain reproducible results (particularly for wireless protocol design), scale to large networks, and study systems that have not yet been implemented. A particular emphasis in ns-3 is a high degree of realism in the models (including frameworks for using real application and kernel code) and integration of the tool with virtual machine environments and testbeds. Very large scale simulations are possible; simulations of hundreds of millions of nodes have been published. ns-3 has been in development since 2005 and has been making regular releases since June 2008. The simulator is written in C++, with bindings for Python scripting, and uses the CMake build system. We use a GPLv2 licensing model and heavily use mailing lists and Zulip chat, but typically not other social media.

FOSSology is an open source license compliance software system and toolkit. As a toolkit you can run license, copyright and export control scans from the command line. As a system, a database and web UI are provided to give you a compliance workflow. License, copyright and export scanners are tools used in the workflow.

Cameras are complex devices that need heavy hardware image processing operations. Control of the processing is based on advanced algorithms that must run on a programmable processor. This has traditionally been implemented in a dedicated MCU in the camera, but in embedded devices, algorithms have been moved to the main CPU to save cost. Blurring the boundary between camera devices and Linux often left the user with no other option than a vendor-specific closed-source solution.

To address this problem the Linux media community is collaborating with the industry to develop a camera stack that is open-source-friendly while still protecting vendor core IP. libcamera was born out of that collaboration and offers modern camera support to Linux-based systems, including traditional Linux distributions, ChromeOS and Android.

RTEMS has been to Venus, circles Mars, is aboard Curiosity, is in the asteroid belt, is on its way to Jupiter, and is circling the sun. It is in use in many high energy physics research labs around the world. There are many RTEMS users who do not belong to the space or physics communities, but our small part in contributing to basic scientific knowledge makes us proud.

The Eclipse Foundation provides our global community of individuals & organizations with a mature, scalable, and business-friendly environment for OSS collaboration and innovation.

Eclipse is an open source community that's focused around key principles of transparency, openness, and vendor neutrality: the work that we do is done in a manner that can be observed by anybody with an interest; project teams welcome new ideas, and invites others to participate; and vendor neutrality ensures that no single vendor can dominate a project and that everybody plays by the same set of rules (a so-called level playing field).

Naturally, Eclipse projects are also all about the code. With over three hundred and sixty (https://projects.eclipse.org/) open source projects covering a diverse set of of technologies, there's something here for everybody.

Eclipse projects build technology in areas such as Internet of Things (https://projects.eclipse.org/technology-type/internet-things), Programming Languages and IDE (https://projects.eclipse.org/technology-type/language), and Runtimes (https://projects.eclipse.org/technology-type/runtime) like Jetty and EE4J (http://www.eclipse.org/ee4j) (currently known as Java EE).

For those students interested in research, we have an entire working group focused on Science (https://projects.eclipse.org/projects/science) where researches from some of the world's most prestigious labs do open source development to support their research areas.

FreeCAD is a general-purpose parametric 3D computer-aided design (CAD) modeler and a building information modeling (BIM) software application with finite element method (FEM) support.

Users can extend the functionality of the software using the Python programming language.

The National Resource for Network Biology (NRNB, https://www.nrnb.org) organizes the development of free, open-source software technologies to enable network-based visualization, analysis, and biomedical discovery. Biomedical research is increasingly dependent on knowledge expressed in terms of networks, including gene, protein and drug interactions, cell-cell and viral-host communication, and vast social networks. Our technologies enable researchers to assemble and analyze these networks and to use them to better understand biological systems and, in particular, how they fail in disease. The NRNB mentoring organization includes projects such as Cytoscape (https://cytoscape.org/), WikiPathways (https://wikipathways.org/), SBML (https://sbml.org/), and cBioPortal (https://cbioportal.org/). This is a great opportunity to work at the intersection of biology and computing! For example, Cytoscape is downloaded over 18,000 times per month by researchers. We take mentoring seriously and are proud of our 95% success rate (https://www.nrnb.org/alumni.html#gsoc-tab) with former students and projects. But don’t take our word for it, read testimonials from prior NRNB students (https://www.nrnb.org/testimonials.html#student-tab) and (https://www.nrnb.org/testimonials.html#mentor-tab).

Synfig is a 2D open-source animation software. It is capable to produce vector artwork and also can work with bitmap images.

TARDIS is a tool that creates synthetic observations (spectra) for exploding stars (supernovae).

A supernova marks the brilliant death throes of a star, during which it outshines its entire galaxy. Through their explosive stellar death, supernovae enrich the Universe with new elements necessary for the formation of planets and life as we know it. From the iron in your blood to the silicon in your laptop, supernovae are responsible for producing many important elements from the primordial hydrogen and helium left over from the Big Bang.

TARDIS provides a link between theory and observations: by creating synthetic spectra from theoretical assumptions and comparing these to observations, we can both interpret data and test models for why, when and how supernova explosions occur. We, the community around TARDIS, are interested in combining astronomy, computer science, statistics and modern software design to build a tool that is useful both in research and teaching alike (with supporting documentation that would, in theory, allow anyone to recreate the project from scratch). Please join us on https://gitter.im/tardis-sn/gsoc.

ENIGMA is a game development environment comprising an IDE, Compiler, and Game Engine.

ENIGMA is meant to be simple to learn and even simpler to work with. ENIGMA makes it refreshingly easy to stand up simple games. Recreating Atari Pong is a job for a handful of minutes. This is true in many modern engines, but unlike most, ENIGMA scales well to positively enormous games, as the engine (and ultimately, all user code) is written in C++.

Users write code in EDL, a language similar to JavaScript (or, more to the point, Game Maker Language) which compiles intermediately to C++. The emitted C++ is optimized based on the game's asset usage, and the result is a C++ game project which can be built by any C++ compiler (we target Clang and GCC). This offers massive portability and library support.

The compiler bundles a C++ parser which crawls the engine for definitions. This theoretically allows users to access library routines directly (e.g. OpenGL), though we recommend against this for portability reasons. This framework is another good surface for GSoC projects, though it's more advanced, so we've left it unexplored in our project ideas list.

To really understand the utility of the project, consider a typical game, which uses rooms (a type of ENIGMA asset) to lay out instances of objects (game entity classes) visually. The objects contain code for specific events (such as step, draw, or keyboard) which can call out to scripts or begin timelines or start movement on paths. ENIGMA's compiler translates this to C++ and builds it against the engine after parsing both to learn how to integrate them.

Climate change science has witnessed an explosion in the amount and types of data that can be brought to bear on the potential responses of the terrestrial carbon cycle and biodiversity to global change. Many of the most pressing questions about global change are not necessarily limited by the need to collect new data as much as by our ability to synthesize existing data. This project specifically seeks to improve this ability. Because no one measurement provides a complete picture, multiple data sources must be integrated in a sensible manner. Process-based models represent an ideal framework for integrating these data streams because they represent multiple processes at different spatial and temporal scales in ways that capture our current understanding of the causal connections across scales and among data types. Three components are required to bridge this gap between the available data and the required level of understanding: 1) a state-of-the-art ecosystem model, 2) a workflow management system to handle the numerous streams of data, and 3) a data assimilation statistical framework in order to synthesize the data with the model.

The Internet Health Report monitors the conditions of networks that compose the Internet. It aims to provide network operators, policymakers, and other stakeholders, with a better understanding of the Internet's infrastructure and its evolution.

When working with different technologies and developers of different programming languages, the productivity of the entire team worsens due to the lack of interoperability and communication between them. If the developers need two technologies which are written in different programming languages, for instance, a C/C++ library called from NodeJS, the team usually needs to port to one of the two languages or write a wrapper around them. Maintaining a port of a library or the plumbing code is frequently error-prone, time-consuming, and does not add any value to the final product.

The main objective of MetaCall is to provide a transparent interoperability in both ways, no matter what language you are using, so you feel like you are using a library written in the same language but in fact, it may be written in C, NodeJS or any other language.

MetaCall currently provides a mechanism to introspect the types and function signatures, which allows us to provide this type info to the caller language. You can have type safety and at the same time avoid boilerplate in both directions.

It addresses the main shortcomings of embedding independent languages separately. Having a common implementation with a plugin architecture allows you to implement newer languages without rewriting more code. With a single solution you get C#, Ruby, Python or any other language you prefer. We can improve the core continuously and add new languages.

Finally, we are using the polyglot runtime in cloud computing so we take advantage of the interoperability capabilities and allow to build complex polyglot distributed systems with ease. It is possible to build monolithic and mono-repo projects that can be distributed and scaled separately through our Function as a Service built on top of MetaCall, allowing the developer to maximize the productivity without the need of DevOps plumbing or thinking about intercommunication protocols and architectural details.

Red Hen Lab is an international distributed cooperative of researchers in multimodal communication. We are senior professors at major research universities, senior developers in technology corporations. We also include junior professors, postdoctoral students, graduate students, undergraduate students, and even a few advanced high school students. Red Hen develops code in Natural Language Processing, ASR, audio parsing, gesture analysis, media analysis, computer vision, and multimodal analysis.

Red Hen's multimodal communication research involves locating, identifying, and characterizing auditory and visual elements in videos and pictures. We may provide annotated clips or images and present the challenge of developing the machine learning tools to find additional instances in a much larger dataset. Some examples are gestures, eye movements, and tone of voice. We favor projects that combine more than one modality, but have a clear communicative function—an example would be floor-holding techniques. Once a feature has been successfully identified in our full dataset of several hundred thousand hours of news videos, cognitive linguists, communication scholars, and political scientists can use this information to study higher-level phenomena in language, culture, and politics and develop a better understanding of the full spectrum of human communication. Our dataset is recorded in a large number of languages, giving Red Hen a global perspective.

For GSoC 2022, we invite proposals from students for components for a unified multimodal processing pipeline, whose aim is to extract information from text, audio, and video, and to develop integrative cross-modal feature detection tasks. Red Hen Lab is directed jointly by Francis Steen (UCLA) and Mark Turner (Case Western Reserve University).

LibreOffice is a modern Free & Open Source Office suite, one of the largest open source projects, and used by millions of users worldwide. LibreOffice is compatible with many file formats like Microsoft® Word, Excel, PowerPoint and Publisher. At its heart though, LibreOffice is built around an open standard, the OpenDocument Format, as its native file format. LibreOffice is developed by users who, just like you, believe in the principles of Free Software and in sharing their work with the world in non-restrictive ways. The development of LibreOffice is supported by The Document Foundation which provides the infrastructure for the project. We believe that users should have the freedom to run, copy, distribute, study, change and improve the software that we distribute. While we do offer no-cost downloads of the LibreOffice suite of programs, Free Software is first and foremost a matter of liberty, not price. We campaign for these freedoms because we believe that everyone deserves them. Though the members of our community hail from many different backgrounds, we all value personal choice and transparency, which translates practically into wider compatibility, more utility, and no end-user lock-in to a single product. We believe that Free Software can provide better-quality, higher-reliability, increased-security, and greater-flexibility than proprietary alternatives. LibreOffice is a large project (approx. 6MLOC), which makes it interestingly complex, but at the same time, provides a place for all sorts of contribution & skills. The community behind LibreOffice is the heart of the project, without which we would not have the resources to continue developing our software. The passion and drive that every individual brings to the community results in collaborative development that often exceeds our own expectations. With tons of different roles in the project, we invite everyone to join us in our work and help us to make LibreOffice known, prosper, and accessible to all.

Kiwix provides copies of websites that can be browsed offline. We run scrapers that will crawl a given website and compress it into a single .zim archive (based on the openZIM format).

The zim files can then be stored locally and read on the fly by Kiwix in such a way that the user experience is similar to being online.

We can fit the entirety of Wikipedia on a regular Android phone, but there are more than 7,000 zim files available in 100+ languages, mostly focused on educational content (e.g. Wikipedia, StackOverflow, Khan Academy, etc.).

Kiwix runs on all platforms (Linux, Windows, Android, etc.) and has around 8 million users worldwide, in pretty much any place you can think of that has limited or no connectivity: prisons, rural schools, refugee camps, even Antarctic bases!

Our big challenge is to make it as easy as possible to access or share offline content.

OpenStreetMap is a crowdsourcing project that creates and distributes free geographic data for the world. Our data is collected by hundreds of thousands of contributors around the globe and released with an open-content license. We allow free access not only to our map products, but all the underlying map data, which powers websites and apps used by billions of people worldwide.

OSM data can be freely used in both open and closed source software, and has attracted many commercial users. Still, the success of OSM wouldn't be possible without open source software and volunteer developers. The database, website and api running on our own servers, the editing tools used by contributors to improve the map, and many of the most popular libraries and end-user applications within the OSM software ecosystem are all open source software, and developed through a community-driven process.

As our Google Summer of Code participation spans this diverse set of software projects, most of which are maintained as independent efforts under the OSM umbrella, contributors will encounter a wide range of programming languages, paradigms and use cases. We hope that we have interesting challenges to offer for any developer, no matter their background!

Liquid Galaxy is a remarkable panoramic system that is tremendously compelling. It started off as a Google 20% project to run Google Earth across a small cluster of PC's and it has grown from there! Open source applications such as the MPlayer video player have been extended to run on Liquid Galaxy. Liquid Galaxy hardware consists of one or more computers driving multiple displays. Liquid Galaxy applications have been developed using a master/slave architecture. The view orientation of each slave display is configured in reference to the view of the master display. Navigation on the system is done from the master instance and the location on the master is broadcast to the slaves over UDP. The slave instances, knowing their own locations in reference to the master, then change their views accordingly. The Liquid Galaxy Project, while making use of Google Earth software, does not develop the Google Earth code-base itself. Google Earth is not open source software, although it is free (as in beer). Instead, the Liquid Galaxy Project works on extending the Liquid Galaxy system with open source software both improving its administration and enabling open source applications, so that content of various types can be displayed in the immersive panoramic environment.

MDAnalysis is a Python library for the analysis of computer simulations of many-body systems at the molecular scale, spanning use cases from interactions of drugs with proteins to novel materials. It is written by scientists for scientists and is used for cutting edge research in biophysics, chemistry, soft-matter physics, and materials research around the world in academia and national research labs. MDAnalysis strives to be highly interoperable and hence a growing number of projects use MDAnalysis as their foundational library or integrate it.

The goal of MDAnalysis is to make it easy for users to analyze data that are produced by simulations (primarily molecular dynamics simulations) that run on some of the largest supercomputers in the world. MDAnalysis accomplishes this goal by providing a toolkit of programming building blocks that provide an abstract Python interface to the simulation data — agnostic of the specific simulation package that produced it — that lends itself to interactive data exploration and rapid prototyping but is also a robust foundational library that can form the basis for new computational tools.

MDAnalysis allows one to read particle-based trajectories such as the ones produced by MD simulations or individual coordinate frames (such as biomolecules in the Protein Databank format) and access the atomic coordinates through NumPy arrays. Together with a powerful selection language and many implemented analysis algorithms, MDAnalysis provides a flexible and fast framework for complex analysis tasks. Welcoming documentation such as the User Guide https://userguide.mdanalysis.org/ make it easy to get started. New releases are downloaded a few thousand times and the academic papers describing MDAnalysis are cited more than almost two thousand times, indicating the widespread use in the academic community.

Every user has work they need to do. The goal of Gentoo is to design tools and systems that allow a user to do that work as pleasantly and efficiently as possible, as they see fit. Our tools should be a joy to use, and should help the user to appreciate the richness of the Linux and free software community, and the flexibility of free software. This is only possible when the tool is designed to reflect and transmit the will of the user, and leave the possibilities open as to the final form of the raw materials (the source code.) If the tool forces the user to do things a particular way, then the tool is working against, rather than for, the user. We have all experienced situations where tools seem to be imposing their respective wills on us. This is backwards, and contrary to the Gentoo philosophy.

Put another way, the Gentoo philosophy is to create better tools. When a tool is doing its job perfectly, you might not even be very aware of its presence, because it does not interfere and make its presence known, nor does it force you to interact with it when you don’t want it to. The tool serves the user rather than the user serving the tool.

The goal of Gentoo is to strive to create near-ideal tools. Tools that can accommodate the needs of many different users all with divergent goals. Don’t you love it when you find a tool that does exactly what you want to do? Doesn’t it feel great? Our mission is to give that sensation to as many people as possible.

The Oppia project aims to empower learners across the globe by providing access to high-quality, engaging education. We envision a world where access to high-quality education is not a privilege but a human right.

The team works on two platforms:

• (a) Oppia Web, which provides an online learning tool that enables anyone to learn from effective and engaging interactive lessons (called 'explorations'), which simulate a one-on-one conversation with a tutor. This format makes it possible for students to learn by doing while getting feedback. The Oppia Web platform also provides the infrastructure needed to support lesson creation and translation.
• (b) Oppia Android, which provides a way for these lessons to be played offline on an Android app that supports low-end devices and does not require Internet connectivity.

As a community, we are also aware that millions of students in underserved communities lack access to the educational resources necessary to effectively learn key skills like basic numeracy. Thus, in addition to developing the Oppia platform, the team has launched and continues to develop a set of free and effective lessons on basic mathematics, supplemented by translations and voiceovers. Students using these lessons have shown strong improvements between pre-and post-tests, and we’ve received lots of positive feedback on them. We are planning to extend this offering to other subjects, based on what students (and the nonprofits working with them) tell us would be most useful.

CircuitVerse is an easy to use digital logic circuit simulator which aims at providing a platform to create, share and learn digital circuits. It can run on almost any device without the need for installing any software. The platform has been designed for use by students, professionals and hobbyists alike. The vision is to develop a community around the platform that will aid students to self-learn digital logic design. The platform is currently used by several universities worldwide. Apart from the simulator, users can create, learn, collaborate and share their work. Teachers can create groups and host assignments on the platform. The platform’s impact has been more evident than ever in the Covid 19 pandemic as CircuitVerse enabled schools and colleges to move their courses online.

GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software radios. It can be used with readily-available low-cost external RF hardware to create software-defined radios, or without hardware in a simulation-like environment. It is widely used in research, industry, academia, government, and hobbyist environments to support both wireless communications research and real-world radio systems.

In brief, a software radio is a radio system which performs the required signal processing in software instead of using dedicated integrated circuits in hardware. The benefit is that since software can be easily replaced in the radio system, the same hardware can be used to create many kinds of radios for many different communications standards; thus, one software radio can be used for a variety of applications!

You can use GNU Radio to write applications to receive and transmit data with radio hardware, or to create entirely simulation-based applications. GNU Radio has filters, channel codes, synchronization elements, equalizers, demodulators, vocoders, decoders, and many other types of blocks which are typically found in signal processing systems. More importantly, it includes a method of connecting these blocks and then manages how data is passed from one block to another. Extending GNU Radio is also quite easy; if you find a specific block that is missing, you can quickly create and add it.

GNU Radio applications can be written in either C++ or Python, while the performance-critical signal processing path is implemented in C++ using processor floating-point extensions where available. This enables the developer to implement real-time, high-throughput radio systems in a simple-to-use, rapid-application-development environment.

ScummVM is a game preservation projects that celebrated its 20th anniversary last year.

FreeBSD is an advanced operating system for server, desktop, and embedded computer platforms. It offers advanced networking, impressive security features, and world class performance. It is used by some of the world's busiest web sites as well as embedded networking and storage devices. FreeBSD source code is the foundation for the PlayStation 5, Junos, the operating system used by Juniper routers to provide the backbone of the Internet, and was the starting point for the core of Apple's OS X (now MacOS). FreeBSD also powers the servers Netflix uses to stream terabits of video every second. It is possible that you are using FreeBSD right now without even realizing it.

The FreeBSD Project began nearly 30 years ago in 1993, but is based on work from the Berkeley Computer Systems Research Group dating back to 1978. Over those years the code base has gone through continuous development, improvement, and optimization. It offers a complete operating system from which students can choose to work on topics in the kernel or userland. In addition to producing an operating system, FreeBSD has incubated the development of software components used by other open source projects including bsnmp, jemalloc, libarchive, and OpenPAM.

FreeBSD has an active mentoring program to welcome new developers into our community. There are currently over 300 developers with write access to our repositories and many more contributors. Many of our past GSoC students have gone on to become FreeBSD developers. We communicate with one another in the many mailing lists, forums, blogs, IRC channels, and user groups all listed on our main website.

R provides a wide variety of statistical and graphical techniques, and is highly extensible. R is often the tool of choice for research in statistical methodology.

R is an integrated suite of software facilities for data manipulation, calculation and graphical display. It includes

• an effective data handling and storage facility,
• a suite of operators for calculations on arrays, in particular matrices,
• a large, coherent, integrated collection of intermediate tools for data analysis,
• graphical facilities for data analysis and display either on-screen or on hardcopy, and
• a well-developed, simple and effective programming language which includes conditionals, loops, user-defined recursive functions and input and output facilities.

The term “environment” is intended to characterize it as a fully planned and coherent system, rather than an incremental accretion of very specific and inflexible tools, as is frequently the case with other data analysis software.

R, like S, is designed around a true computer language, and it allows users to add additional functionality by defining new functions. Much of the system is itself written in the R dialect of S, which makes it easy for users to follow the algorithmic choices made. For computationally-intensive tasks, C, C++ and Fortran code can be linked and called at run time. Advanced users can write C code to manipulate R objects directly.

Many users think of R as a statistics system. We prefer to think of it of an environment within which statistical techniques are implemented. R can be extended (easily) via packages. There are about eight packages supplied with the R distribution and many more are available through the CRAN family of Internet sites covering a very wide range of modern statistics.

R has its own LaTeX-like documentation format, which is used to supply comprehensive documentation, both on-line in a number of formats and in hardcopy.

The LLVM Project is a collection of modular and reusable compiler and toolchain technologies. Despite its name, LLVM has little to do with traditional virtual machines. The name LLVM itself is not an acronym; it is the full name of the project.

LLVM began as a research project at the University of Illinois, with the goal of providing a modern, SSA-based compilation strategy capable of supporting both static and dynamic compilation of arbitrary programming languages. Since then, LLVM has grown to be an umbrella project consisting of a number of subprojects, many of which are being used in production by a wide variety of commercial and open source projects as well as being widely used in academic research.

In addition to official subprojects of LLVM, there are a broad variety of other projects that use components of LLVM for various tasks. Through these external projects you can use LLVM to compile Ruby, Python, Haskell, Rust, D, PHP, Pure, Lua, Julia, and a number of other languages. A major strength of LLVM is its versatility, flexibility, and reusability, which is why it is being used for such a wide variety of different tasks: everything from doing light-weight JIT compiles of embedded languages like Lua to compiling Fortran code for massive super computers.

GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable.

Octave is continually being upgraded. Student projects may also involve developing or upgrading Octave Forge packages, which can be loaded to provide additional specialized functions that supplement those provided in Core Octave.

CERN-HSF (High-Energy Physics Software Foundation) is the umbrella organization for high-energy physics-related projects in GSoC. The HEP Software Foundation (http://hepsoftwarefoundation.org/) facilitates the coordination of common international efforts in high-energy physics software and computing.

CERN (European Organization for Nuclear Research, https://home.cern) has participated in GSoC since 2011 as the CERN-SFT group, which provides common software for CERN's experiments. In 2017, the program expanded to include many software projects from the whole field of high-energy physics. The vast majority of our GSoC projects do not require any physics knowledge.

The experiments at CERN, such as the Large Hadron Collider, the world’s largest and most powerful particle accelerator (http://home.cern/topics/large-hadron-collider) try to answer fundamental questions about the Universe. For example, what is the nature of mass? What are the elementary building blocks of the Universe? What was the early Universe like? What is the nature of dark matter and dark energy? Why is there an asymmetry between matter and antimatter? In 2012, LHC experiments announced the discovery of a new particle, the Higgs Boson, that helps explain how particles obtain mass. Also, CERN is the birthplace of the World Wide Web. Today, particle physicists are working on analyzing the data from the experiments to study the properties of the newly discovered particle and to search for new physics, such as dark matter or extra dimensions. This requires a lot of sophisticated software.

The open-source high-energy physics projects to which students can contribute during GSoC span many high-energy physics software projects: data analysis, detector and accelerator simulation, event reconstruction, data management and many others. We look forward to your contributions!
