Calculate Linux 20 Now Available For Download


  • Gentoo-Based Calculate Linux 20 Now Available For Download

    Calculate Linux 20, a Gentoo-based operating system, is ready to be installed on your computer. Calculate Linux 20 is based on Gentoo 17.1 and comes with several desktop environment choices, such as Cinnamon, KDE, Xfce, MATE, and more. Unfortunately for some users, the operating system is now 64-bit only. Yes, with version 20, the developers have chosen to kill the 32-bit variants. While some people will be upset, it is definitely the correct choice -- 32-bit only processors are very old at this point. You can likely get a better 64-bit machine for a steal at a thrift store these days.

    With 2019 almost over, we turn our sights to a new decade with 2020. Soon we will celebrate the new year by partying, eating good food, and watching the Times Square Ball drop on TV. Sadly, Dick Clark is dead, but his legacy lives on through Ryan Seacrest.

    But what if you want to celebrate 2020 in a more... nerdier way? Well, I have some good news. Calculate Linux 20 is now available for download! Yes, the Gentoo-based operating system is ready to be installed on your computer. Since it is version 20, that makes it perfect for ringing in 2020.

GCC 11 Compiler Performance Benchmarks With Various Optimization Levels, LTO

Given the recent forum discussion stemming from the -O3 optimization level still too unsafe for the Linux kernel (in part due to older, buggy compilers) and some users wondering about the current -O2 versus -O3 compiler optimization level impact, here is a fresh round of reference benchmarks using GCC 11.1 on Fedora Workstation 33 looking at various optimization levels and optimizations tested on dozens of different application benchmarks to see the overall impact on performance. With the recent optimization level discussions and not having done any thorough optimization level comparison tests and link-time optimization (LTO) testing of the recently released GCC 11, here is this Monday article for those interested in compiler optimizations.

  • the end of freenode

    My first experience with IRC was in 1999. I was in middle school, and a friend of mine ordered a Slackware CD from Walnut Creek CDROM. This was Slackware 3.4, and contained the GNOME 1.x desktop environment on the disc, which came with the BitchX IRC client. At first, I didn’t really know what BitchX was, I just thought it was a cool program that displayed random ascii art, and then tried to connect to various servers. After a while, I found out that an IRC client allowed you to connect to an IRC network, and get help with Slackware. At that time, freenode didn’t exist. The Slackware IRC channel was on DALnet, and I started using DALnet to learn more about Slackware. Like most IRC newbies, it didn’t go so well: I got banned from #slackware in like 5 minutes or something. I pleaded for forgiveness, in the way redolent of a middle schooler. And eventually, I got unbanned and stuck around for a while. That was my first experience with IRC. [...] For a few years, all was well, until the end of July 2002, when DALnet started being the target of Distributed Denial of Service attacks. We would of course, later find out that these attacks were at the request of Jason Michael Downey (Nessun), who had just launched a competing IRC network called Rizon. [...] In early 2006, lilo launched his Spinhome project. Spinhome was a fundraising effort so that lilo could get a mobile home to replace the double-wide trailer he had been living in. Some people saw him trying to fundraise while being the owner of freenode as a conflict of interest, which lead to a falling out with a lot of staffers, projects, etc. OFTC went from being a small network to a much larger network during this time. One side effect of this was that the atheme project got spun out into its own organization:, which continues to exist in some form to this day. The project was founded on the concept of promoting digital autonomy, which is basically the network equivalent of software freedom, and has advocated in various ways to preserve IRC in the context of digital autonomy for years. In retrospect, some of the ways we advocated for digital autonomy were somewhat obnoxious, but as they say, hindsight is always 20/20. [...] Self-hosting is really what makes IRC great: you can run your own server for your community and not be beholden to anyone else. As far as IRC goes, that’s the future I feel motivated to build. This concludes my coverage of the freenode meltdown. I hope people enjoyed it and also understand why freenode was important to me: without lilo‘s decision to take a chance on a dumbfuck kid like myself, I wouldn’t have ever really gotten as deeply involved in FOSS as I have, so to see what has happened has left me heartbroken.

  • A few thoughts on Fuchsia security

    Of course, under the hood, a lot is different. We built a brand new message-passing kernel, new connectivity stacks, component model, file-systems, you name it. And yes, there are a few security things I'm excited about.

  • Claudio Cambra: First week of Google Summer of Code 2021

    A year ago I’d just finished my History degree and I had no idea how to code. This year, I’m taking part in Google Summer of Code! I’m super happy to get the chance to learn more about how KDE software works, and to finally contribute to a project I’ve been using for years. Over the summer, I’ll be working with KDE developers to create productivity-focused components for Plasma Mobile that work with Akonadi, KDE’s personal information management framework. Akonadi is a super useful piece of kit: it allows developers to tap into a user’s synchronised e-mails, contacts, calendars, providing a seamless experience in productivity tools. I’ll be working on this project with my mentor Carl Schwan, who also helped me during my time doing Season of KDE, and Devin Lin.

  • Bas Nieuwenhuizen: Making Reading from VRAM less Catastrophic

    In an earlier article I showed how reading from VRAM with the CPU can be very slow. It however turns out there there are ways to make it less slow. The key to this are instructions with non-temporal hints, in particular VMOVNTDQA. The Intel Instruction Manual says the following about this instruction: “MOVNTDQA loads a double quadword from the source operand (second operand) to the destination operand (first operand) using a non-temporal hint if the memory source is WC (write combining) memory type. For WC memory type, the nontemporal hint may be implemented by loading a temporary internal buffer with the equivalent of an aligned cache line without filling this data to the cache. Any memory-type aliased lines in the cache will be snooped and flushed. Subsequent MOVNTDQA reads to unread portions of the WC cache line will receive data from the temporary internal buffer if data is available. “ (Intel® 64 and IA-32 Architectures Software Developer’s Manual Volume 2) This sounds perfect for our VRAM and WC System Memory buffers as we typically only read 16-bytes per instruction and this allows us to read entire cachelines at time. It turns out that Mesa already implemented a streaming memcpy using these instructions so all we had to do was throw that into our benchmark and write a corresponding memcpy that does non-temporal stores to benchmark writing to these memory regions.

  • Adrift - Alan Pope's blog

    Over the weekend I participated in FOSS Talk Live. Before The Event this would have been an in-person shindig at a pub in London. A bunch of (mostly) UK-based podcasters get together and record live versions of their shows in front of a “studio audience”. It’s mostly an opportunity for a bunch of us middle-aged farts who speak into microphones to get together, have a few beers and chat. Due to The Event, this year it was a virtual affair, done online via YouTube. Joe Ressington typically organised the in-person events, but with a lack of skills in video streaming, Martin Wimpress and Marius Quabeck stepped in to run the show behind-the-scenes.

  • Vincent Fourmond: Solution for QSoas quiz #2: averaging several Y values for the same X value

    This post describes two similar solutions to the Quiz #2, using the data files found there. The two solutions described here rely on split-on-values. The first solution is the one that came naturally to me, and is by far the most general and extensible, but the second one is shorter, and doesn't require external script files.
