  • 15 ways to leave your cloud provider

    Avoid concentration

    While it’s tempting to keep things simple by using the same cloud for everything, the danger is that one cloud becomes a big point of failure. Microsoft, for instance, bought GitHub and this should give Azure users a reason to start thinking about storing their code in other repositories. Or at the very least, make sure it is pushed regularly to backups. The same goes for the other clouds.

    Use open source

    Proprietary code has many wonderful aspects. Sometimes the business model delivers some amazing software. There are many times in life when you get what you pay for and that can be true in the software world too. But only open source software offers you the freedom to move the code easily and quickly without begging, “Mother, may I?” Richard Stallman always said that he was after “free as in speech, not free as in beer.”

    Avoid proprietary tools

    The cloud providers usually offer two types of products: open source clones and proprietary tools. While the closed source products may offer plenty of tempting options and attractive innovations, the threat of losing service is too great to risk using them. If you choose the MySQL service at AWS, you can move to MySQL on your own box. If you choose a proprietary tool, you can’t.

  • Jan-Erik Rediger: Three-year Moziversary

    Has it really been 3 years? I guess it has. I joined Mozilla as a Firefox Telemetry Engineer in March 2018, I blogged twice already: 2019, 2020.

    And now it's 2021. 2020 was nothing like I thought it would and still been a lot like I said last year at this point. It's been Glean all over the year, but instead of working from the office and occasionally meeting my team in person, it's been working from home for 12 months now.

    In September of last year I officially became the Glean SDK tech lead and thus I'm now responsible for the technical direction and organisation of the whole project, but really this is a team effort. Throughout the year we made Project FOG happen. At least the code is there and we can start migrating now. It's far from finished of course.

  • Firefox 86 TOTALLY FIXES the cookie problem.

    Firefox 86 is the latest release of Firefox and it's got two killer features. One of them is how Firefox handles cross-origin requests and cookies: by silo-ing each web page. Now, when you visit a new site for the first time, any assets loaded from other websites (read: Google Analytics) don't have your login information from your Google Account. This is CRITICAL!

  • Community Member Monday: Rafael Lima

    I am a university professor in Brazil, and I teach and research optimization applied to management sciences. In my work I often need to write papers and prepare spreadsheets to analyze data, and for that I’ve been using LibreOffice for over a year now. I have been working with supply chain optimization problems such as vehicle routing, network design and facility location.

    I have always been an enthusiast of Open Source, since my undergraduate days in 2001. At the time I started using Linux and most of my current research work is done using FOSS tools. The dynamics of how open source software is developed is a topic that has always caught my attention.

    Outside of work, I like to spend my free time practicing sports (mostly playing tennis) and whenever I have the opportunity I like to travel to new places. And obviously, like many tech enthusiasts, I like gaming too!

  • Learning the Poke language in Y minutes

    Mohammad-Reza Nabipoor has written a nice short tutorial called "Learn
    the Poke Language in Y minutes". The tutorial has the form of a Poke
    program itself, and I think it really highlights the most uncommon
    (and useful!) features of our domain-specific language.

    The tutorial is also available as part the poke source distribution in
    `doc/learn-poke-language-in-y-minutes.pk' so you can play with it. Find
    the plain source file here.

    Mohammad will be improving and updating it as the language grows.
    Thanks Mohammad, and happy poking!

  • Swiss National Bank releases paper regarding CBDC and GNU Talers

    The Swiss National Bank has released a paper on the advantages of GNU Talers over blockchain and account-based digital money transactions for Central Bank Digital Currency.

    A possible technical implementation was presented in a paper by the Swiss National Bank (SNB), discussing the merits of token-based digital cash called GNU Talers. The Swiss Bank has been developing the concept of ‘Taxable Anonymous Libre Electronic Reserves’, or Taler for short. Interested parties have been able to try out the cryptographically secured digital ‘coins’ for some time.

  • FLOSS Weekly 625: Endless Sky - Jonathan Steck

    Jonathan Steck joins Jonathan Bennett and Dan Lynch talk to about Endless Sky, an open source video game reminiscent of Elite and Escape velocity, and one that even hearkens back to Spacewar! On FLOSS Weekly, Steck and the show hosts talk about the game itself and the community around it. The project has attracted an interesting bunch of contributors, mainly through its presence on Steam as a free game. There are several challenges the project has overcome, from the sabbatical of the founder, to managing the continued growth and interest in the game. The game is addictive, and the conversation is just as good.

  • How To Install Dig on CentOS 8 - idroot

    In this tutorial, we will show you how to install the Dig on CentOS 8. For those of you who didn’t know, Dig (Domain Information Groper) is handy to perform DNS lookup and investigate DNS-related issues, right from the terminal. But for some reason, it doesn’t exist on the latest version of CentOS or RHEL. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you through the step-by-step installation of the Dig on a CentOS 8.

  • The Linux Kernel & GNOME Desktop Preparing For Privacy Screen Support - Phoronix

    Over the past year there has been an uptick in Linux developers from different vendors working on laptop privacy screen support under Linux. When it comes to the support with newer Lenovo ThinkPad laptops, it looks like that kernel support could soon land and the GNOME desktop is already preparing to support this feature.  Select Lenovo laptops in recent years have offered a built-in "Privacy Guard ePrivacy Filter" for limiting the viewing angles of the laptop with a simple push of a button on the ThinkPad laptops. While the effectiveness of the "ePrivacy" feature is debatable in its current form and with the current work from home craze / limited travel making the feature less pressing at the moment, the Linux support is coming together.

  • Gigabyte Motherboard WMI Temperature Driver Queued Ahead Of Linux 5.13 - Phoronix

    Earlier this month I reported on a WMI temperature driver for Gigabyte motherboards being worked on by an independent developer. That "gigabyte-wmi" driver is now slated for inclusion in the upcoming Linux 5.13 cycle.  This driver exposes the Windows Management Instrumentation (WMI) temperature sensors under Linux. When writing originally about this new driver it was only tested on a Gigabyte X570 Aorus Pro WiFi motherboard but since then has been tested and confirmed to also be working on the likes of the Gigabyte's B550M DS3H, B550 Gaming X V2, and Z390 I Aorus Pro WiFi motherboards as well.

  • A New Gigabyte Motherboard WMI Temperature Driver Will Likely Arrive In Linux 5.13

    Linux users with newer Gigabyte and ASUS motherboards for AMD processors have to compile a out-of-tree version of the it87 to get hardware sensors and fan control working, and sensor support for the very newest motherboards is a shot in the dark even if you do that. That may change for Gigabyte-users with Linux 5.13 as a new, Gigabyte-specific WMI driver has been merged into the Linux kernels platform drivers git tree. It will likely be merged into Linux 5.13 when the merge window opens.

  • Rust Support In The Linux Kernel Undergoing Another Round Of Discussions

    Last month the initial infrastructure for allowing the Rust programming language to be used within the Linux kernel landed in the Linux-Next tree for more widespread testing ahead of its possible inclusion in the mainline kernel. Now a "request for comments" has been started again on the kernel mailing list around the prospects of Rust code for the Linux kernel.  Kernel developer Miguel Ojeda started this latest "RFC" proposal on the Linux kernel mailing list. The lengthy mailing list post outlines the beliefs of the involved developers over adding Rust code to the kernel, the benefits like improved memory safety, and more.

  • Google Supports Getting Rust Into The Linux Kernel

    It should come as little surprise -- especially given the recent news of Google allowing Rust to be used for Android system-level code -- but engineers at the search giant are in support of Rust code being used within the mainline Linux kernel.  In addition to yesterday's Rust RFC for the Linux kernel and that discussion still taking place on the Linux Kernel Mailing List, Google engineers on the Google Security Blog have penned their own piece on the matter.
