  • Firefox Nightly: These Weeks in Firefox: Issue 105
  • New JavaScript syntax support in add-on developer tools | Mozilla Add-ons Community Blog

    It’s been a year since we last added support for new JavaScript syntax to the add-ons linter. In that time we’ve used it to validate over 150,000 submissions to AMO totalling hundreds of millions of lines of code. But it has been a year, and with both Javascript and Firefox are constantly and quickly evolving, the list of JavaScript features Firefox supports and what the AMO linter allows have drifted apart.

    This drift is not an accident; Firefox and AMO don’t keep the same cadence on supported features, and this is deliberate. Upcoming JavaScript features are spread across different EcmaScript proposal stages, meaning different features are always in different stages of readiness. While Firefox often trials promising new JavaScript features that aren’t “finished” yet (stage 4 in the ECMAScript process) to better test their implementations and drive early adoption, the AMO team takes a different approach intended to minimize friction developers might face moving their addons between browsers. To that end, the AMO team only adds support for “finished”, stage 4 features to the linter.

  • Jonathan Dowland: Cost models for evaluating stream-processing programs

    As I wrote, last week I attended the UK Systems Research 2021 and gave two (or 2½, or 3) talks. my PhD talk is entitled "Picking a winner: cost models for evaluating stream-processing programs".

  • Gremlin detection bigly improved and a NUL problem avoided

    Gremlin" is my name for an invisible character other than a plain whitespace, a linefeed or a horizontal tab. Gremlins can cause errors in data processing and can also make it harder to detect duplicate records in a data table.

    A few years ago I wrote a gremlin-detector script (called "gremlins") for A Data Cleaner's Cookbook that works on UTF-8-encoded plain text files. The script has since had a few minor updates, but I've now rewritten "gremlins" from scratch to make it faster and more informative. This post explains the new script, which is presented in full at the bottom of this webpage.

  • The Mocking will continue, until CI improves | die-welt.net

    One might think, this blog is exclusively about weird language behavior and yelling at computers… Well, welcome to another episode of Jackass!

    Today's opponent is Ruby, or maybe minitest , or maybe Mocha. I'm not exactly sure, but it was a rather amusing exercise and I like to share my nightmares Wink

    It all started with the classical "you're using old and unmaintained software, please switch to something new".

    The first attempt was to switch from the ci_reporter_minitest plugin to the minitest-ci plugin. While the change worked great for Foreman itself, it broke the reporting in Katello - the tests would run but no junit.xml was generated and Jenkins rightfully complained that it got no test results.

    While investigating what the hell was wrong, we realized that Katello was already using a minitest reporting plugin: minitest-reporters. Loading two different reporting plugins seemed like a good source for problems, so I tried using the same plugin for Foreman too.

    Guess what? After a bit of massaging (mostly to disable the second minitest-reporters initialization in Katello) reporting of test results from Katello started to work like a charm. But now the Foreman tests started to fail. Not fail to report, fail to actually run. WTH‽

  • Support the FSF through the GNU Press shop with great holiday picks

    Greetings from the GNU Press shop! My name is Davis Remmel, and I am excited to introduce myself as the new operations assistant at the Free Software Foundation (FSF). These past few weeks I've been working through our backlog of orders, and I'm pleased to say that we are just about caught up and processing new orders on our normal timeline.

    If you were thinking about getting a gift for that GNU-loving friend or family member, now is the time to place that order! If you're in the US, and if you place your order by Friday, December 17, there's a good chance that package will arrive on, or before, December 24.

    [...]

    For privacy lovers (or those who have ever uttered the word, "cryptography"), we have a NeuG USB True Random Number Generator (RNG). Your cryptographic keys will be stronger than an ox, without any need to trust your CPU's definition of "random." I recommend this RNG in conjunction with our anti-surveillance webcam stickers, which don't leave residue and can also cover microphone holes.

  • Intel Posts Updated Driver & Sample Code For "Software Defined Silicon" - Phoronix

    Back in September Intel originally posted Linux patches for "Software Defined Silicon" for being able to activate extra CPU features present in the processor's silicon but not exposed by default unless the cryptographically secure process with this SDSi driver was performed. Intel appears to be moving toward allowing licensable processor features that can be activated after the fact and today a new version of that SDSi Linux driver appeared.

Samsung, Red Hat to Work on Linux Drivers for Future Tech

The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. Read more

  • How to install go1.19beta on Ubuntu 22.04 – NextGenTips

    In this tutorial, we are going to explore how to install go on Ubuntu 22.04 Golang is an open-source programming language that is easy to learn and use. It is built-in concurrency and has a robust standard library. It is reliable, builds fast, and efficient software that scales fast. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel-type systems enable flexible and modular program constructions. Go compiles quickly to machine code and has the convenience of garbage collection and the power of run-time reflection. In this guide, we are going to learn how to install golang 1.19beta on Ubuntu 22.04. Go 1.19beta1 is not yet released. There is so much work in progress with all the documentation.

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. 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 the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
