  • 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).

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.
