  • PDL: Episode VI - a New Book

    I would love a new PDL Book. One that's completely different from the original to maximize the surface of engagement to a new audience. As a "sequel", It would have the advantage of being able to refer the reader to the first book for longer explanations and be able to jump right into how to solve significant problems. brian d foy has just finished his Mojolicious book, so I bet he's got loads of free time on his hands. (although I remember him in the middle of writing it in 2018, so you may have to wait a bit)

    The premise behind the PDL Book is that it takes you on a tour of the features, trying to expose the useful parts as quickly as possible and yet still give you the Full Monty. In today's world, many coders, including yours truly, are unwilling adherents of SOOP (Stack Overflow Oriented Programming) with the attention span of 5-year olds who want to dive into the middle of a book and work their way backwards trying to understand the solution. I think it's an issue of motivation and, honestly, I'm surprised you've read this far before going off and checking your phone. Smile

OpenMandriva Is The Latest Linux Distribution Using Zstd To Compress Packages

Filed under
MDV

Similar to Fedora's move last year to compress RPMs with Zstd rather than XZ for much faster decompression speeds and a better compression ratio at the highest level, OpenMandriva has now enacted a similar change.

This OpenMandriva change also comes just days after Arch Linux switched to Zstd for a ~1300% speedup in total decompression time, among other Linux distributions as well switching to Zstandard for either offering a comparable compression ratio to existing algorithms or better, depending upon the compression level utilized. But the big win in switching the packaging to Zstd compression is the significantly faster decompression times.

OpenMandriva Can Now Clang Its Linux Kernel Build For This LLVM Focused Distribution

Filed under
MDV

OpenMandriva is one of the few Linux distributions (and arguably the only prominent one) that uses LLVM Clang as its default compiler toolchain over GCC for building its packages and the preferred C/C++ compiler exposed to its users. One of the last hold outs for this Clang'ed Linux distribution has been the kernel build but that is now no longer a blocker.

With the new LLVM Clang 9.0 release, it's now possible to use LLVM Clang to compile the mainline Linux kernel for x86_64 and Arm without needing any out-of-tree patches. In my testing of Clang 9 + Linux 5.3 it's worked out well with a few exceptions like the AMDGPU driver having issues, but those few remaining headaches are being worked out so Clang'ing the Linux kernel works well for users and helps ensure code/compiler portability of the kernel.

An Easy Fix for a Stupid Mistake

Filed under
MDV

I waited a long time for Mageia 7 and for OpenMandriva Lx 4. When both distros arrived, I was very happy.

But new distros bring changes, and sometimes it is not easy to adapt. Mageia 7 has been rock-solid: it is doing a great job in my laptop and both in my daughter's desktop and in mine. There is one thing, though. I have been avoiding a strange mesa update that wants to remove Steam.

OpenMandriva is also fantastic, but this new release provided options like rock, release, and rolling. When I first installed the distro, I chose rock because I was shying away from the rolling flavor. Eventually, I had to move to rolling because that was the only way in which I could manage to install Steam in both my laptop and desktop machines.

Mageia 7.1, Mageia 7 with Ryzen 3000 hardware support

Filed under
MDV

The timing for Mageia 7, just prior to the recent release of the new AMD Ryzen 3000 series of CPU’s, didn’t play nicely. Namely, there was an issue with the system starting up on these new CPU’s that prevented any type of installation, except for a net install. So, the only solution was to release a new set of installation media, which are available to download here.

It’s very important to note that if you have a working system, there is nothing that you need to address. This release is primarily to fix installation on systems with the above CPU’s.

Best Open Source Slack Alternatives for Team Communication

You are here: Home / List / Best Open Source Slack Alternatives for Team Communication Best Open Source Slack Alternatives for Team Communication Last updated February 25, 2020 By Ankush Das Leave a Comment Brief: Here, we shall take a look at the best open source slack alternatives that you can choose to communicate with your team at work. Slack is one of the most popular team communication services for work. Some may call it a glorified IRC but that doesn’t impact its popularity. It is available for free with additional features offered in its paid plans. Though Slack can be installed on Linux thanks to an Electron app but it is not open source, neither the client nor the server. In this article, I’ll list a few open source Slack alternatives that you can try. Read more

Dual-Boot GNU/Linux and Android

  • Planet Computers' clamshell phone can dual-boot Android and Linux

    Planet Computers' laptop-like Cosmo Communicator phone just became that much more useful to its audience of very particular power users. The Cosmo now supports a promised multi-boot function, letting you run Android (both regular and rooted), Debian Linux and TWRP on the same device without one replacing the other. You'll have to partition your storage and know your way around a boot menu, but this will give you a way to run Linux apps or otherwise experiment with your phone. You won't lose over-the-air updates for Android by installing Linux, Planet Computers said. The multi-boot firmware is available for free, and there are instructions for installing Debian and other software. This still isn't for the faint-hearted. However, it also represents one of the few instances where a phone maker has officially enabled support for operating systems besides the one that ships with the device. The Cosmo is also fairly well-suited to Linux thanks to its keyboard -- you won't have to jump through hoops to use the command line.

  • How can IT manage Android Things devices in the enterprise?

    Recent versions of Google's Android OS support a wider range of devices via the Android Things program's APIs and managing some of the newer devices can seem complicated at first. Thankfully, the underlying OS is essentially the same on all Android devices, so the EMM platform management and enrollment processes are usually similar for Android Things devices. The challenge for mobile admins is to develop a version of Android -- using the Android SDK and Android Things APIs -- that functions on these dedicated devices.

Update on Linux support: creation of a CERN Linux community forum

For those, a CERN Linux community forum has been created. Users will be able to post issues that they encounter when using non-CERN-supported Linux distributions and to post solutions. Users are also encouraged to post articles with comments and ideas that could help make this forum more dynamic and useful to them. Various methods for printing and using AFS, SSH, ROOT and other tools at CERN can be found on the internet. The CERN Linux community forum aims to collect these methods, as well as new ones that may be created directly in it. Read more

Python Programming

  • Introduction to Python SQL Libraries

    All software applications interact with data, most commonly through a database management system (DBMS). Some programming languages come with modules that you can use to interact with a DBMS, while others require the use of third-party packages. In this tutorial, you’ll explore the different Python SQL libraries that you can use. You’ll develop a straightforward application to interact with SQLite, MySQL, and PostgreSQL databases.

  • Introduction to Image Processing in Python with OpenCV

    In this tutorial, we are going to learn how we can perform image processing using the Python language. We are not going to restrict ourselves to a single library or framework; however, there is one that we will be using the most frequently, the Open CV library. We will start off by talking a little about image processing and then we will move on to see different applications/scenarios where image processing can come in handy. So, let's begin!

  • Talking to API's and goodlooking tools

    One of my go-to locations for security news had a thread recently about a tool called VTScan. I really liked the idea of not having to go through the browser overhead to check files against multiple scan engines. Although the tool (which is itself a basic vt-cli spinoff) already existed, I was looking for a new challenge, I decided to roll my own and add a few cool features! I'll have a thorough look at how python talks to API's with requests and I look at turning all this API data into a nice GUI application with click. I hope to give you some idea's for CLI styling in the future so I can see more awesome tools by you all!

  • From a rejected Pycon talk to a new project.

    Like many others, my talk proposal (early draft here) for Pycon US was rejected. So, I decided to spend some time putting everything in a new project instead. (Documentation here.) It is still a rough draft, but usable ... and since I've mentioned it in a few other places, I thought I should mention it here as well.
