  • Saving your battery as well as your privacy? New Brave for Android claims 5% power reduction

    Brave has updated its Android web browser and claims a 5 per cent battery saving versus the previous release.

    The new release is version 1.5.120, already available in the Play Store, which has been "completely rebuilt over the past few months", according to the company. Brave also said the code repository is now shared between the mobile and desktop versions, a unified codebase that will enable "easier implementations of features". Brave continues to be based on the Google-sponsored Chromium project.

  • Mozilla installs Scheduled Telemetry Task on Windows with Firefox 75
  • The Talospace Project: Firefox 75 on POWER

    Firefox 75 seems to build uneventfully on this Raptor Talos II and as always this post is being typed in the new version. I'm not particularly enamoured of the zooming address bar and I'm sure you won't be able to turn it off eventually, but for now you can. A number of the developer-facing features are quite compelling, though. In addition, if you're on Wayland (Xorg forever), Firefox on Wayland now has H.264 VA-API and full WebGL support; I don't know how well these work on Wayland on ppc64le and I'm not going to be the one to tell you, but I'm sure some of you folks will try.

  • We could all do with a bit of empathy in our systems, says Mozilla as it ships Firefox 75 in the thick of global pandemic

    Mozilla has squeezed out version 75 of the Firefox browser, crediting "empathy" in its systems for an ability to continue emissions even as Microsoft and Google hit the pause button on their Chromium-based apps.

    The release came hot on the heels of fixes aimed at plugging holes in both version 74 and the Extended Support Release (ESR) of Firefox.

    Version 75 of the newly third-placed browser (depending how you take your market-share statistics) includes some significant search improvements, with results arising from searches in the address bar featuring popular keywords in a bold font. The address bar itself also enlarges when the user opts to do a search, replete with a larger font.

    As well as the cosmetics (some of which bring Firefox more into line with the competition and also aligns the Linux version with other desktop incarnations), Direct Composition is being integrated for Firefox on Windows to speed things along and some Penguinistas will be delighted to find the thing available in Flatpak.

  • Andy Wingo: multi-value webassembly in firefox: a binary interface

    Hey hey hey! Hope everyone is staying safe at home in these weird times. Today I have a final dispatch on the implementation of the multi-value feature for WebAssembly in Firefox. Last week I wrote about multi-value in blocks; this week I cover function calls.

    on the boundaries between things

    In my article on Firefox's baseline compiler, I mentioned that all WebAssembly engines in web browsers treat the function as the unit of compilation. This facilitates streaming, parallel compilation of WebAssembly modules, by farming out compilation of individual functions to worker threads. It also allows for easy tier-up from quick-and-dirty code generated by the low-latency baseline compiler to the faster code produced by the optimizing compiler.

    There are some interesting Conway's Law implications of this choice. One is that division of compilation tasks becomes an opportunity for division of human labor; there is a whole team working on the experimental Cranelift compiler that could replace the optimizing tier, and in my hackings on Firefox I have had minimal interaction with them. To my detriment, of course; they are fine people doing interesting things. But the code boundary means that we don't need to communicate as we work on different parts of the same system.

  • 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.
