  • Future-proofing Firefox’s JavaScript Debugger Implementation

    We’ve made major improvements to JavaScript debugging in Firefox DevTools over the past two years. Developer feedback has informed and validated our work on performance, source maps, stepping reliability, pretty printing, and more types of breakpoints. Thank you. If you haven’t tried Firefox for debugging modern JavaScript in a while, now is the time.

    [...]

    The JavaScript debugger in Firefox is based on the SpiderMonkey engine’s Debugger API. This API was added in 2011. Since then, it has survived the addition of four JIT compilers, the retirement of two of them, and the addition of a WebAssembly compiler. All that, without needing to make substantial changes to the API’s users. Debugger imposes a performance penalty only temporarily, while the developer is closely observing the debuggee’s execution. As soon as the developer looks away, the program can return to its optimized paths.

  • Spotty privacy practices of popular period trackers

    We don’t think twice when it comes to using technology for convenience. That can include some seriously personal aspects of day-to-day life like menstruation and fertility tracking. For people who have periods, understanding the natural cycles of their body plays an important role in spotting irregularities, family planning and just generally being healthy. Writing all of that down can be a hassle, which is why more than 50 million women worldwide use a period tracker.

  • More privacy means more democracy

    The 2020 U.S. presidential election season is underway, and no matter your political lean, you want to know the facts. What do all of these politicians believe? How do their beliefs align with mine? What have they done to support issues I care about? What do they plan to do policy-wise if elected? After all, a well-informed electorate is critical to any democracy.

  • [Mozilla's Patrick Cloke Gets] New Position at New Vector

    I’m excited to share that a few weeks ago I started a new position at New Vector! They’re the company behind Matrix, “an open network for secure, decentralized communication”.

    I’ll be working on the reference backend server software used in Matrix (Synapse). The tech stack overlaps with what I was using: mostly Python code (specifically Twisted). Additionally, most of my work will be open-sourced (and developed in the open)! I’ve already had a few pull requests merged and a couple of my changes are already in the current version of Synapse (v1.11.1).

System76 Thelio Major Proves To Be A Major Player For Linux Workstations

For the past two months we have been testing the System76 Thelio Major and it's been working out extremely well with performance and reliability. The Thelio Major offering with options for Intel Core X-Series or AMD Ryzen Threadripper and resides between their standard Thelio desktop with Ryzen/Core CPUs and the Thelio Massive that sports dual Intel Xeon CPUs. The Thelio Major is the platform we have been using for all of our AMD Ryzen Threadripper 3990X testing and it's been working out great. The Thelio Major besides having Threadripper and Core X-Series CPU options can be configured with up to 256GB of RAM, up to two GPUs, and up to 46TB of storage for really yielding incredibly powerful Linux workstation performance potential.

Deprecating support for the Linux kernel

Running on the Hurd was always a goal for Guix, and supporting multiple kernels is a huge maintenance burden. As such it is expected that the upcoming Guix 1.1 release will be the last version featuring the Linux-Libre kernel. Future versions of Guix System will run exclusively on the Hurd, and we expect to remove Linux-Libre entirely by Guix 2.0. The Linux kernel will still be supported when using Guix on "foreign" distributions, but it will be on a best-effort basis. We hope that other distributions will follow suit and adopt the Hurd in order to increase security and freedom for their users. Read more Also: Guix deprecating support for the Linux kernel
