  • Arm Has Been Working To Boost The Chrome/Chromium Browser Performance

    Arm engineers have been working to speed-up the open-source Chromium web browser on 64-bit ARM (AArch64) and ultimately to flow back into Google's Chrome releases. Their focus has been around Windows-on-Arm with the growing number of Windows Arm laptops coming to market, but the Chromium optimizations also benefit the browser on Linux too.

    Arm has been focusing on Chromium optimizations not only for the Chromium/Chrome browsers itself but also for software leveraging the likes of CEF and Electron that rely upon Chromium code for rendering.

  • TenFourFox FPR17b1 available

    TenFourFox Feature Parity Release 17 beta 1 is now available (downloads, hashes, release notes). SourceForge seems to have fixed whatever was making TenFourFox barf on its end which now might actually be an issue over key exchange. For a variety of reasons, but most importantly backwards compatibility, my preference has been to patch up the NSS security library in TenFourFox to support new crypto and ciphers rather than just drop in a later version. We will see if the issue recurs.

    This release fixes the "infinite loop" issue on Github with a trivial "hack" mitigation. This mitigation makes JavaScript slightly faster as a side-effect but it's because it relaxes some syntax constraints in the runtime, so I don't consider this a win really. It also gets rid of some debug-specific functions that are web-observable and clashed on a few pages, an error Firefox corrected some time ago but missed my notice. Additionally, since 68ESR newly adds the ability to generate and click on links without embedding them in the DOM, I backported that patch so that we can do that now too (a 4-year-old bug only recently addressed in Firefox 70). Apparently this functionality is required for certain sites' download features and evidently this was important enough to merit putting in an extended support release, so we will follow suit.

    I also did an update to cookie security, with more to come, and cleared my backlog of some old performance patches I had been meaning to backport. The most important of these substantially reduces the amount of junk strings JavaScript has hanging around, which in turn reduces memory pressure (important on our 32-bit systems) and garbage collection frequency. Another enables a fast path for layout frames with no properties so we don't have to check the hash tables as frequently.

  • Week notes - 2019 w47 - worklog

    Week Notes. I'm not sure I will be able to commit to this. But they have a bit of revival around my blogging reading echo chamber. Per revival, I mean I see them again.

    The Open Data Institute just started one with a round about them. I subscribed again to the feed of Brian Suda and his own week notes. Alice Bartlett has also a very cool personal, down to earth and simple summary of her week. I love that she calls them weaknotes She's on week 63 by now.

  • Marco Zehe: My extended advent calendar

    This year, I have a special treat for my readers. On Monday, November 25, at 12 PM UTC, I will start a 30 day series about everything and anything. Could be an accessibility tip, an how-to about using a feature in an app I use frequently, some personal opinion on something, a link to something great I came across on the web… I am totally not certain yet. I have ideas about some things I want to blog about, but by far not 30 of them yet.

  • Mike Hoye: Navigational Instruments

    A decade ago I got to sit in on a talk by one of the designers of Microsoft Office who’d worked on the transition to the new Ribbon user interface. There was a lot to learn there, but the most interesting thing was when he explained the core rationale for the redesign: of the top ten new feature requests for Office, every year, six to eight of them were already features built into the product, and had been for at least one previous version. They’d already built all this stuff people kept saying they wanted, and nobody could find it to use it. It comes up periodically at my job that we have the same problem; there are so many useful features in Firefox that approximately nobody knows about, even people who’ve been using the browser every day and soaking in the codebase for years. People who work here still find themselves saying “wait, you can do that?” when a colleague shows them some novel feature or way to get around the browser that hasn’t seen a lot of daylight. In the hopes of putting this particular peeve to bed, I did a casual survey the other day of people’s favorite examples of underknown or underappreciated features in the product, and I’ve collected a bunch of them here. These aren’t Add-ons, as great as they are; this is what you get from Firefox out of the proverbial box. I’m going to say “Alt” and “Ctrl” a lot here, because I live in PC land, but if you’re on a Mac those are “Option” and “Command” respectively. Starting at the top, one of the biggest differences between Firefox and basically everything else out there is right there at the top of the window, the address bar that we call the Quantumbar.

Programming: Cutelyst, C/C++, Perl and Python

  • Cutelyst 2.13 and ASql 0.19 released – Dantti's Blog

    Cutelyst the C++/Qt Web Framework and ASql the ASync SQL library for Qt applications got new versions. Thanks to the work on ASql Cutelyst got some significant performance improvements on async requests, as well as a new class called ASync, which automatically detaches the current request from the processing chain, and attaches later on when it goes out of scope. With the ASync class you capture it on your ASql lambda and once the query result arrives and the lambda is freed and the ASync object gets out of scope and continues the processing action chain.

  • LLVM Lands Very Basic Support For AMD Zen 3 CPUs

    While AMD has landed Znver3 support in GNU Binutils, the company hasn't yet sent out patches for either the GCC or LLVM/Clang compilers in setting up the Zen 3 target with its new instructions or optimized scheduling model / cost table. But a basic implementation has been merged to LLVM for allowing "-march=znver3" based on the limited public details thus far. Merged to mainline LLVM 12 yesterday was a basic implementation allowing for -march=znver3 targeting that basically flips on the new instructions known to be supported by Zen 3. Beyond Zen 2, it flips on INVPCID, PKU, VAES, and VPCLMULQDQ. There are also a few other instructions supported by Zen 3 as outlined in this earlier article.

  • CY's Take on PWC#083 | Moments on Perl or other Programming Issues [blogs.perl.org]

    I found that I use "and/or" quite frequently in writing. I know, (mathematical-)logically we only need "or". It seems to me to be a language tricky part as the use of gender neutral terms.

  • Warning about Python3 update in latest -current | Alien Pastures

    Warning for people running Slackware-current and have 3rd party packages installed (who doesn’t) that depend on Python3. That includes you who are running KDE Plasma5! The “Sun Oct 25 18:05:51 UTC 2020” update in Slackware-current comes with a bump in the Python3 version (to 3.9) which is incompatible with software which already has been compiled against an older version of Python3 (like 3.8). I found 26 of my own packages on my laptop that depend on Python3 and they are all probably going to break when upgrading to the latest slackware-current. This includes Plasma5 ‘ktown’ packages but also several of my DAW packages.

  • This Linux laptop is a beast - Juno Computers Neptune 15 First Impressions

    I received this beast on tuesday. It's made by a company you might not have heard of, called Juno computers. They operate ouf of London, and much like Slimbook or Tuxedo, they offer laptops based on Clevo designs, as well as desktops. Disclaimer: I haven't received any money for this video, and I don't get to keep the laptop either, so be nice ;)

ScummVM Android Love

Our new and shiny Android port for ScummVM v2.2.1 is now live on the Google Play Store. After quite a long period of dedicated work from our team developers, and a month of public beta testing by members of our community who helpfully reported quite a few issues for us to address, we are finally ready to give you the stable release for our ScummVM Android app. This app has been significantly re-written and tested on modern Android devices, running up to Android 10+. It includes new features which bring it up to speed with the desktop ScummVM application, such as FluidSynth support, Cloud Saves and more localization choices for the UI. Also included is the Local File Server (LAN) feature, whereby your device can act as a temporary file server allowing you to download files (eg. save files and even the config file) or upload new ones (eg. game data) using a web browser from a PC or another client.
