  • Chris H-C: Distributed Teams: A Test Failing Because It’s Run West of Newfoundland and Labrador

    When Firefox starts up the first time, it doesn’t know where it is. And it needs to know where it is to properly make a first guess at what language you want and what search engines would work best. Google’s results are pretty bad in Canada unless you use “google.ca”, after all.

    But while Firefox doesn’t know where it is, it does know is what timezone it’s in from the settings in your OS’s clock. On top of that it knows what language your OS is set to. So we make a first guess at which search region we’re in based on whether or not the timezone overlaps a US timezone and if your OS’ locale is `en-US` (United States English).

    What this fails to take into account is that United States English is the “default” locale reported by many OSes even if you aren’t in the US. And how even if you are in a timezone that overlaps with the US, you might not be there.

  • Fluent 1.0: a localization system for natural-sounding translations

    Fluent is a family of localization specifications, implementations and good practices developed by Mozilla. It is currently used in Firefox. With Fluent, translators can create expressive translations that sound great in their language. Today we’re announcing version 1.0 of the Fluent file format specification. We’re inviting translation tool authors to try it out and provide feedback.

  • Mark Surman: Getting crisper about ‘better AI’

    As I wrote a few weeks back, Mozilla is increasingly coming to the conclusion that making sure AI serves humanity rather than harms it is a key internet health issue. Our internet health movement building efforts will be focused in this area in the coming years.

    In 2019, this means focusing a big part of our investment in fellowships, awards, campaigns and the Internet Health Report on AI topics. It also means taking the time to get crisper on what we mean by ‘better’ and defining a specific set of things we’d like to see happen around the politics, technology and use of AI. Thinking this through now will tee up work in the years to come.

    We started this thinking in an ‘issue brief’ that looks at AI issues through the lens of internet health and the Mozilla Manifesto. It builds from the idea that intelligent systems are ultimately designed and shaped by humans — and then looks at areas where we need to collectively figure out how we want these systems used, who should control them and how we should mitigate their risks. The purpose of this brief is to spark discussions in and around Mozilla that will help us come up with more specific goals and plans of action.

  • Mozilla reacts to European Parliament plenary vote on EU Terrorist Content regulation

    As the recent atrocities in Christchurch underscored, terrorism remains a serious threat to citizens and society, and it is essential that we implement effective strategies to combat it. But the Terrorist Content regulation passed today in the European Parliament is not that. This legislation does little but chip away at the rights of European citizens and further entrench the same companies the legislation was aimed at regulating. By demanding that companies of all sizes take down ‘terrorist content’ within one hour the EU has set a compliance bar that only the most powerful can meet.

    Our calls for targeted, proportionate and evidence-driven policy responses to combat the evolving threat, were not accepted by the majority, but we will continue to push for a more effective regulation in the next phase of this legislative process. The issue is simply too important to get wrong, and the present shortfalls in the proposal are too serious to let stand.

  • Mark J. Wielaard: Valgrind 3.15.0 with improved DHAT heap profiler

    Julian Seward released valgrind 3.15.0 which updates support for existing platforms and adds a major overhaul of the DHAT heap profiler. There are, as ever, many refinements and bug fixes. The release notes give more details.

    Nicholas Nethercote used the old experimental DHAT tool a lot while profiling the Rust compiler and then decided to write and contribute A better DHAT (which contains a screenshot of the the new graphical viewer).

  • A better DHAT

    DHAT is a heap profiler that comes with Valgrind. (The name is short for “Dynamic Heap Analysis Tool”.) It tells your where all your heap allocations come from, and can help you find the following: places that cause excessive numbers of allocations; leaks; unused and under-used allocations; short-lived allocations; and allocations with inefficient data layouts. This old blog post goes into some detail.

    In the new Valgrind 3.15 release I have given DHAT a thorough overhaul.

    The old DHAT was very useful and I have used it a lot while profiling the Rust compiler. But it had some rather annoying limitations, which the new DHAT overcomes.

    First, the old DHAT dumped its data as text at program termination. The new DHAT collects its data in a file which is read by a graphical viewer that runs in a web browser. This gives several advantages.

Valgrind 3.15 Released With Overhauled DHAT Profiler

  • Valgrind 3.15 Released With Overhauled DHAT Profiler

    Valgrind 3.15 has been released, the programming utility famous for catching memory leaks and helping with memory debugging/profiling.

    Valgrind 3.15 most notably overhauls DHAT, their Dynamic Heap Analysis Tool. DHAT looks at how programs are using heap allocations and is able to identify possible leaks, excessive turnovers, excessive transients, useless/underused allocations, and blocks with inefficient layouts.

  • 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.
