  • Computer Science University of Cuba, 18 years creating the future

    Among the many programs conceived there are the Nova system, a Cuban distribution of GNU / Linux that promotes the values ​​of sovereignty and technological independence, and are national leaders in the country's migration to Free Software and Open Source technologies.

  • New Ensemble Graphics Toolkit Optimized for 32-bit MPUs Running Linux Operating System

    Graphical user interfaces (GUIs) and interactive touchscreen displays provide intuitive user experiences in applications from robotic and machine controls to medical user interfaces, automotive instrumentation and home and building automation systems. A well-designed GUI enables users to process information more quickly and interact more effectively with a product. Microchip Technology Inc. (Nasdaq: MCHP) today announced a new GUI development toolkit for its portfolio of 32-bit microprocessors (MPUs) running Linux, helping designers of industrial, medical, consumer and automotive graphical displays to reduce development cost and time-to-market.

  • AMDGPU For Linux 5.10 Brings PCIe DPC Recovery, More RDNA2 Updates

    Another batch of AMDGPU kernel driver updates have landed in DRM-Next ahead of the upcoming Linux 5.10 kernel cycle. Queued already on the AMD Radeon side for Linux 5.10 has been more RDNA2 code for Navy Flounder and Sienna Cichlid, Southern Islands DC display code support, and other low-level updates. With this latest pull that was sent out on Friday and merged to DRM-Next on Monday there was more work, albeit mostly lower-level. There were yet more Sienna Cichlid and Navy Flounder updates but not Dimgrey Catfish or VanGogh that just appeared in RadeonSI as other RDNA2 devices.

  • What’s an Open Source Program Office?

    Open Source Program Offices help companies create and manage an open source strategy in terms of the adoption, use, support, participation, and development of open source software. OSPOs help companies understand both the benefits and potential drawbacks of open source software and how to balance those considerations to meet the company’s unique business goals. As Brian Proffitt explains on the Red Hat blog, “it’s not about implementing open source for the sake of open source. It's also about aligning open source tools and techniques with the needs of the organization.” The role of an OSPO is “to align the efforts of all relevant parts of an organization—engineering, sales, marketing, content creation—toward making open source methodologies and outputs successful,” Proffitt says.

  • Red Hat partners with Skillsbuild.org to offer retraining solution

    The impact of COVID-19 on the jobs market has been substantial, but we know that enterprises are still looking for qualified IT professionals. Red Hat is working to help those affected by COVID-19 gain the skills and knowledge that can help them find their next opportunity.

  • "A place for public code" +++ FSFE support +++ Job vacancy
  • Raspberry Pi powered e-paper display takes months to show a movie
  • Intel Announces Atom x6000E Series "Elkhart Lake", 11th Gen Core Tigerlake-UP3

    Given that they are IoT/embedded products where Linux dominates and all of the Elkhart Lake and Tigerlake open-source/Linux patches we have been noting over the past number of months, the Linux support should be quite ready to go for these new Intel offerings as soon as they begin appearing in actual devices. Those are the highlights from today's announcement and once we can get our hands on such hardware we'll certainly be putting them through much benchmarking to test the claims.

Programming Leftovers

  • How my students taught me to code

    "Hello, I'm Miss Jess, and my students taught me how to code." When I say this to new students, they often think I misspoke. But it's true. Coding always interested me, but it seemed inaccessible. Then my students taught me to code a video game during a few lunch breaks. Their encouraging advice and suggestions helped me create my first video game using Scratch. The game was simple. It was about a monkey catching bananas as they fell from the sky. If you caught a ripe banana, you earned points.

  • ssh-copy-id: call for testing

    After a prolonged period of neglect, I've finally got round to putting the various patches I had laying around into some sort of order, and pushing them somewhere public, so it would be great if people could test them.

    There are two branches that I'd like people to try:

    and

  • How to rename columns in Pandas Dataframe

    In this tutorial, we will cover various methods to rename columns in pandas dataframe in Python. Renaming or changing the names of columns is one of the most common data wrangling task. If you are not from programming background and worked only in Excel Spreadsheets in the past you might feel it not so easy doing this in Python as you can easily rename columns in MS Excel by just typing in the cell what you want to have. If you are from database background it is similar to ALIAS in SQL. In Python there is a popular data manipulation package called pandas which simplifies doing these kind of data operations.

  • How to use Ansible to update your Django web app

    Now, as you have overcome or evaded the reefs, shoals and swirls of initial development and deployment and your appetite grows, you ask “How do I automate the update and restart of my web app when I change the code?” There is already one simple and elegant method on our blog, that uses one of the possible push to publish methods, but this time we will dip our toes into vast waters of Ansible automation. You may think that using Ansible for a simple task like this is overkill, and it’s a valid thought, but our example is a good practice case that introduces multiple elements that can be used later for much bigger projects. That’s why, instead of writing a simple bash or python script, we will build a full Ansible playbook with accompanying configuration.

  • Using bash’s shopt builtin to manage Linux shell behavior

    If you haven’t tried it yet, you might be surprised by the many features of shopt. While it works like a Linux command, it’s actually a bash shell builtin that allows you to change many things about that shell’s behavior. One option, for example, allows the shell to fix minor typos when you type directory names. To demonstrate, in the first cd command shown below, the directory name, bin, is typed with an extra letter and the shell complains and gives up:

Security and Tor

  • Find security issues in Go code using gosec

    It's extremely common now to encounter code written in the Go programming language, especially if you are working with containers, Kubernetes, or a cloud ecosystem. Docker was one of the first projects to adopt Golang, Kubernetes followed, and many new projects select Go over other programming languages. Like any other language, Go has its share of strengths and weaknesses, which include security flaws. These can arise due to issues in the programming language itself coupled with insecure coding practices, such as memory safety issues in C code, for example. Regardless of why they occur, security issues need to be fixed early in development to prevent them from creeping into shipped software. Fortunately, static analysis tools are available to help you tackle these issues in a more repeatable manner. Static analysis tools work by parsing source code written in a programming language and looking for issues.

  • NXLog Enterprise Edition 5.1: Providing capabilities to further harden enterprises’ security
