  • Robot Framework with Selenium and Python: All You Need to Know

    With 5000+ stars and 1500+ forks on GitHub, Robot framework has been a go-to-option for many organizations who are aiming for Agile and Test Driven Development (TDD) where developers should write functional code only when there is a test that has failed. Robot framework allows acceptance testing, behaviour driven testing, Robotic Process Automation (RPA), and Acceptance test-driven development (ATDD). It offers an extensible keyword driven approach to perform automation testing. The learning curve is simple as you don’t need to have a programming experience to get started with the Robot framework. Robot framework is written in Python, however, it is not restricted to that. You can implement keywords in Robot framework using Python, Java, JavaScript, Perl, .Net and PHP.

  • How and why I built a menu planning application: What's on the Menu?

    The application that I build can, of course, be used for searching recipes. Additionally, a list of persons could be maintained with their list of allergies, favourite ingredients and when the user decides to plan a meal or cook for them, then appropriate recipes would be suggested which fulfils the needs of the people being planned for. It also learns to suggest recipes based on previous selections.

  • Mixing text and chemistry toolkits

    This is part of a series of essays about using chemfp to work with SD files at the record and simple text level. Chemfp has a text toolkit to read and write SDF and SMILES files as records, rather than molecules. It also has a chemistry toolkit I/O API to have a consistent way to handle structure input and output when working with the OEChem, RDKit, and Open Babel toolkits. In this essay I'll combine the two, so chemfp reads records from an SD file, which are then passed to a chemistry toolkit for further parsing, then chemfp adds a data item back to the original record instead of converting the toolkits molecule into a new SDF record.

  • Colin Watson: Porting Launchpad to Python 3: progress report

    Launchpad still requires Python 2, which in 2020 is a bit of a problem. Unlike a lot of the rest of 2020, though, there’s good reason to be optimistic about progress. I’ve been porting Python 2 code to Python 3 on and off for a long time, from back when I was on the Ubuntu Foundations team and maintaining things like the Ubiquity installer. When I moved to Launchpad in 2015 it was certainly on my mind that this was a large body of code still stuck on Python 2. One option would have been to just accept that and leave it as it is, maybe doing more backporting work over time as support for Python 2 fades away. I’ve long been of the opinion that this would doom Launchpad to being unmaintainable in the long run, and since I genuinely love working on Launchpad - I find it an incredibly rewarding project - this wasn’t something I was willing to accept. We’re already seeing some of our important dependencies dropping support for Python 2, which is perfectly reasonable on their terms but which is starting to become a genuine obstacle to delivering important features when we need new features from newer versions of those dependencies. It also looks as though it may be difficult for us to run on Ubuntu 20.04 LTS (we’re currently on 16.04, with an upgrade to 18.04 in progress) as long as we still require Python 2, since we have some system dependencies that 20.04 no longer provides. And then there are exciting new features like type hints and async/await that we’d like to be able to use.

  • Artificial intelligence as Free Software with Vincent Lequertier

    For the seventh episode of our Software Freedom Podcast we talk with Vincent Lequertier about transparency, fairness, and accessibility as crucial criteria for artificial intelligence (AI) and why it is important for our society to release AI software under a Free Software license. Our guest for the seventh episode of the Software Freedom Podcast is Vincent Lequertier. Vincent is a member of the Free Software Foundation Europe and is researching AI in the health care sector. Together we discuss the use and development of artificial intelligence from a Free Software perspective. Vincent explains what AI actually is and why it is important for our society to release AI software under a Free Software license. We discuss why the criteria of transparency, fairness and accessibility are important when working with artificial intelligence and how they relate to Free Software. Finally, we also discover what challenges AI is facing in the future and whether we should be afraid of the increasing use of this technology in our daily lives.

NVIDIA GeForce vs. AMD Radeon Vulkan Neural Network Performance With NCNN

With having added Tencent's NCNN tests to the Phoronix Test Suite with Vulkan acceleration, here is a look at the real-world impact by using RealSR-NCNN for scaling up with RealSR. Various NVIDIA GeForce and AMD Radeon graphics cards were tested for this initial NCNN / RealSR-NCNN Vulkan comparison. This is our first time looking at how well Vulkan performs in this area with the current state of the Linux drivers. The GeForce hardware was tested with the latest 450 series proprietary driver while on the Radeon side it was with Linux 5.9 and Mesa 20.3-devel using the RADV Vulkan driver. One of the Tencent developers working on NCNN has commented as well that using RADV's ACO offers a big boost for the performance, which fortunately is the current default for the RADV Vulkan driver.

Kernel Space: Trenchboot, RAID10, Spelling Mistakes and Initcalls

  • Trenchboot Secure Launch Support For Linux Sees New Patches

    For a while now Oracle engineers and others have been working on Trenchboot as a means of secure launch/boot support when paired with the likes of Intel TXT and AMD SKINIT for trusted execution and configuring each piece of the software boot chain for trusted/secure handling. The latest kernel patches have been sent out for review for secure launching of the kernel. Earlier this year Oracle engineers sent out Linux kernel patches for Trenchboot while on Thursday the newest work surfaced.

  • Linux 5.10 To See RAID10 DISCARD Improvement - From 259 Seconds To Less Than 1 Second

    Queued today into the block subsystem's "-next" area ahead of the Linux 5.10 cycle kicking off next month are some MD RAID enhancements. In particular, thanks to Red Hat's Xiao Ni is improved RAID10 discard request handling. The change with a set of five SSDs in a RAID10 array on a test system dropped the mkfs.xfs time for creating an XFS file-system taking 4 minutes 39 seconds to less than 1 second... Quite a noticeable difference in that scenario.

  • Colin King: Kernel janitor work: fixing spelling mistakes in kernel messages

    The Linux 5.9-rc6 kernel source contains over 300,000 literal strings used in kernel messages of various sorts (errors, warnings, etc) and it is no surprise that typos and spelling mistakes slip into these messages from time to time. To catch spelling mistakes I run a daily automated job that fetches the tip from linux-next and runs a fast spelling checker tool that finds all spelling mistakes and then diff's these against the results from the previous day. The diff is emailed to me and I put my kernel janitor hat on, fix these up and send these to the upstream developers and maintainers. The spelling checker tool is a fast-and-dirty C parser that finds literal strings and also variable names and checks these against a US English dictionary containing over 100,000 words. As fun weekend side project I hand optimized the checker to be able to parse and spell check several millions lines of kernel C code per second.

  • Initcalls, part 2: Digging into implementation

    In the first part of this blog post series on Linux kernel initcalls, we looked at their purpose, their usage, and ways to debug them (using initcall_debug or FTrace). In this second part, we'll go deeper into the implementation of initcalls, with a look at the colorful __device_initcall() macro, the rootfs initcall, and how modules can be executed.
