  • Mozilla Thunderbird: EFail and Thunderbird, What You Need To Know

    DO NOT DISABLE ENCRYPTION. We’ve seen recommendations from some outlets to stop using encrypted Email altogether. If you are sending sensitive data via Email, Thunderbird still recommends using encryption to keep those messages safe. You should, however, check the configuration of the applications you use to view encrypted EMail. For Thunderbird, follow our guidelines below to protect yourself.

  • Debugging Modern Web Applications

    Building and debugging modern JavaScript applications in Firefox DevTools just took a quantum leap forward. In collaboration with Logan Smyth, Tech Lead for Babel, we leveled up the debugger’s source map support to let you inspect the code that you actually wrote. Combined with the ongoing initiative to offer first-class JS framework support across all our devtools, this will boost productivity for modern web app developers.

    Modern JS frameworks and build tools play a critical role today. Frameworks like React, Angular, and Ember let developers build declarative user interfaces with JSX, directives, and templates. Tools like Webpack, Babel, and PostCSS let developers use new JS and CSS features before they are supported by browser vendors. These tools help developers write simpler code, but generate more complicated code to debug.

  • Firefox Performance Update #8

    Talos is a framework that we use to measure various aspects of Firefox performance as part of our continuous integration pipeline.

    There are a number of Talos “suites”, where each suite contains some number of tests. These tests, in turn, report some set of numbers that are then stored and graphable via our graph viewer here.

    Here’s a full list of the Talos tests, including their purpose, the sorts of measurements they take, and who’s currently a good person to ask about them if you have questions.

    A lot of work has been done to reduce the amount of noise in our Talos tests, but they’re still quite sensitive and noisy. This is why it’s often necessary to do 5-10 retriggers of Talos test runs in order to do meaningful comparisons.

    Sometimes Talos detects regressions that aren’t actually real regressions1, and that can be a pain. However, for the times where real regressions are caught, Talos usually lets us know much faster than Telemetry or user reports.

    Did you know that you can get profiles from Try for Talos runs? This makes it much simpler to diagnose Talos regressions. Also, we now have Talos profiles being generated on our Nightly builds for added convenience!

  • This Week in Rust 234
  • Thoughts on retiring from a team

    The Rust Community Team has recently been having a conversation about what a team member’s “retirement” can or should look like. I used to be quite active on the team but now find myself without the time to contribute much, so I’m helping pioneer the “retirement” process. I’ve been talking with our subteam lead extensively about how to best do this, in a way that sets the right expectations and keeps the team membership experience great for everyone.

  • Rust turns three

    Three years ago today, the Rust community released Rust 1.0 to the world, with our initial vision of fearless systems programming. As per tradition, we’ll celebrate Rust’s birthday by taking stock of the people and the product, and especially of what’s happened in the last year.

    [...]

    Finally, the Rust community continues to work on inclusivity, through outreach programs like Rust Reach and RustBridge, as well as structured mentoring and investments in documentation to ease contribution. For 2018, a major goal is to connect and empower Rust’s global community, which we’re doing both through conference launches in multiple new continents, as well as work toward internationalization throughout the project.

Ubuntu, Debian, RHEL, and CentOS Linux Now Patched Against "Foreshadow" Attacks

Both Canonical and Red Hat emailed us with regards to the L1 Terminal Fault security vulnerability, which are documented as CVE-2018-3620 for operating systems and System Management Mode (SMM), CVE-2018-3646 for impacts to virtualization, as well as CVE-2018-3615 for Intel Software Guard Extensions (Intel SGX). They affect all Linux-based operating system and machines with Intel CPUs. "It was discovered that memory present in the L1 data cache of an Intel CPU core may be exposed to a malicious process that is executing on the CPU core. This vulnerability is also known as L1 Terminal Fault (L1TF). A local attacker in a guest virtual machine could use this to expose sensitive information (memory from other guests or the host OS)," reads the Ubuntu security advisory. Read more

Hands-on with Linux Mint Debian Edition 3 Beta

I have been out of touch for the past six months, because I accepted a teaching position in Amsterdam. The amount of time that required, and the weekly commute from Switzerland (yes, really, weekly), was vastly more than I expected, and left me no time to do justice to my blog. But now I am back again, and determined to manage my time more effectively and keep up with blogging. Although I haven't been writing, I certainly have been keeping up with news and developments in the Linux world. What really inspired me to get busy and write again was the announcement of LMDE 3 (Cindy) Beta. Hooray! How long have we been waiting for this? It feels like years. Oh, that's because it has been years. Read more

  • Video Shows Hotel Security at DEF CON Joking About Posting Photos of Guests' Belongings to Snapchat

    But the room check captured on video suggests the walkthroughs are subject to abuse by hotel personnel who may use them as opportunity to snoop on guests or take and post images for amusement. And accounts of other searches that involved hotel security staff refusing to show ID or showing insufficient ID, and displaying bullying and threatening behavior to guests in occupied rooms, raises questions about the legality of the searches and the tactics and training of security personnel.

    The memorandum required that an extensive interagency process take place before the U.S. government embarks on any cyberattacks. Trump reversed the rules to try and ease some of those restrictions, which critics argued were detrimental to launching the attacks quickly, according to the Journal.
