Kraft Version 0.95

Filed under
KDE
Linux

The authors are happy to announce the new release 0.95 of Kraft. Kraft is free desktop software for managing office documents like quotes and invoices in the small enterprise for the Linux desktop.

With version 0.95 we do a big step forward in the way of generating documents: Until now (more than fifteen years!) Kraft uses the ReportLab python library to create high quality PDF documents.

While this has served us well, it has always been cumbersome to adopt the template for users needs. ReportLab uses a XML format as the template which has a bit of a steep learning curve and is not really easy with syntax.

AMD AOCC 2.2 Helping Squeeze Extra Performance Out Of AMD EPYC 7002 "Rome" CPUs

Filed under
Graphics/Benchmarks

At the end of June AMD quietly released a new version of the AMD Optimizing C/C++ Compiler. Noticing the new release this week, here are some benchmarks of AOCC 2.2 up against LLVM Clang 10 and GCC 10 with Ubuntu Linux while running from an AMD EPYC 7742 2P server for looking at the performance gains possible with the compiler optimizations.

AMD AOCC 2.2 rebases the Zen-focused compiler against upstream LLVM/Clang 10.0 code-base. While the Optimizing "C/C++" Compiler, the Fortran language support continues being improved upon by leveraging LLVM's FLANG. With AOCC 2.2, Fortran 2008 features are present in FLANG along with other Fortran improvements. AOCC 2.2 also has "enhanced high-level optimizations" focused on the AMD EPYC 7002 series, machine dependent optimizations for EPYC 7002 series, updated AMD Math Libraries (AMDLibM 3.3), and LLVM's LLD linker is now the default. AOCC 2.2 is quite a hearty release but a bit unfortunate AMD doesn't do more to promote AOCC as two months past release this is the first time I heard of the new release when being curious about any summer updates.

Why I have a problem with AppImages on Linux

Filed under
Linux

I get why AppImages exist. They were the precursors for Flatpak and Snaps and made it possible for developers to create portable, universal applications that could run on any Linux distribution.

That, my friends, is a great idea. It's also one that both Flatpak and Snap packages have succeeded to do. On my primary machine (a System76 Thelio), I install applications via source, apt, Snap and Flatpak--I don't discriminate. As long as an application will install and run as expected, I'll install it, regardless of the package format.

With one exception: AppImages.

I do not like AppImages and I believe it's time developers stopped using them, but I get why they do. AppImages aren't actually installed on systems. Instead, they are sort of like the containers of desktop applications, without having to rely on an installed engine like Docker. You simply download an AppImage, give it executable permission, and run it. The application in question should open and you could use it. Simple, right?

  • Swap Detector: Open source tool for detecting API usage errors

    GrammaTech has released Swap Detector, an open source tool that enables developers and DevOps teams to identify errors due to swapped function arguments, which can also be present in deployed code.

    [...]

    Modern software development involves the use of third-party APIs, libraries, and/or frameworks that are complex, rapidly evolving, and sometimes poorly documented. According to industry estimates, open source components can represent up to 90% of the code in the average application. Meanwhile, API usage errors are a common source of security and reliability vulnerabilities.

    “Traditional static-analysis techniques do not take advantage of the vast wealth of information on what represents error-free coding practices available in the open-source domain,” says Alexey Loginov, VP of Research at GrammaTech. “With Swap Detector we applied Big Data analysis techniques, what we call Big Code analysis, to the Fedora RPM open-source repository to baseline correct API usage. This allowed us to develop error-detection capabilities that far exceed the scalability and accuracy of conventional approaches to program analysis.”

  • Challenges, priorities, and progress in anti-censorship technology at Tor

    This blog post seeks to bring clarity to the modus operandi of the Tor Project in the anti-censorship space by providing a summary of the challenges we face, the priorities we focus on, and the progress we have made so far related to our circumvention technology. Censorship circumvention is a complex and ever evolving problem, and this blog post summarizes our approach in tackling it. Please feel free to ask any related question in the comments. Thanks to hanneloresx's translation, you can find a Chinese version of this blog post below.

    [...]

    Some Internet Service Providers (ISP) block the domain www.torproject.org, making it difficult for their users to download a copy of Tor Browser. Our service GetTor can help these users get Tor Browser despite this: simply send an email to gettor@torproject.org, which will automatically respond with alternative download links for Tor Browser. These download links point to GitHub, GitLab, the Internet Archive, and Google Drive. At least one of these hosting providers should be accessible to each of our users. For example, users from China can download Tor Browser from our GitHub mirror.

    Once you have your copy of Tor Browser, you are ready to connect to the Tor network. Unfortunately, some ISPs interfere yet again, aided by technology that either blocks the IP addresses of Tor relays and/or detects the Tor protocol dynamically, by inspecting network traffic that passes the ISP's perimeter—so-called deep packet inspection (DPI).

    If you are unable to directly connect to the Tor network, you need to use bridges. Bridges are unlisted Tor relays and, depending on the bridge type, can obfuscate network traffic in a way that's more difficult for ISPs to detect. The simplest method of censorship circumvention in Tor Browser is to use our default bridges—a set of a dozen bridges that are part of Tor Browser. These bridges are essentially public, which is why more effective censorship systems such as China's Great Firewall (GFW) block them, but they are still effective in many places like Iran. Take a look at our Tor Browser manual to learn how to enable default bridges.

Which is why I don’t understand their pricing model change, except in terms of, “they’ve decided to abandon small developers completely.” After a little scouting around, I decided that MapBox completely fit the bill (and whose rates are more like what Google used to charge), and that Leaflet, an open-source Javascript library, could make for a very easy conversion. It took a little work to make the conversion, because Leaflet out of the box doesn’t support the drawing of great circles, but I wrote a plugin that does it.

  • Valve announce new Chat Filtering and a big change to Steam Wallet Codes

    Valve continue to roll out new experiments with their Steam Labs, one of which is now live which you can try out with special Chat Filtering.

    As the name easily suggests, it will enable you to filter out commonly used strong profanity and slurs sent via chat all across Steam. If you choose to join the experiment and enable it, the filtering will be applied across Steam Chat, games that support it and eventually they may roll it out across "more forms of user-generated content". They said that it basically moves the filtering they built for games like CS:GO, Destiny 2, and Dota 2 and puts it directly into your Steam settings.

Records are breaking everywhere it seems, as once again it has been eclipsed. The International 10, now has a prize pool of $34,539,661 from the Battle Pass (plus other purchases like the Collector's Cache) and it's still going up with plenty of time to spare as Valve announced before that it will continue until September 19.

  • Interaction and microcopy: UX best practices for the setup process

    Sometimes, signing up for a service or setting up a new account can be stressful, even with the convenience of online-everything. As a user, you may second guess yourself in the process: Did I miss an important step? Was I supposed to click that button? This uncertainty is understandable. You need to get something done, but there are a few things standing in your way. And if the user interface (UI) isn’t designed well or the copy isn’t clear, then it’s safe to say the experience may not be all that pleasant.

    Thankfully, setup processes don’t always have to be nerve-wracking. By putting extra effort into the user experience (UX), you may just be able to transform an intricate process into a few easy clicks. Let’s take a look at some UX design and copy best practices—and a real-life Red Hat use case—that will hopefully help you make your next product setup process a bit easier for users.

Linux Developers Continue Evaluating The Path To Adding Rust Code To The Kernel

Development
Linux

As mentioned back in July, upstream Linux developers have been working to figure out a path for adding Rust code to the Linux kernel. That topic is now being further explored at this week's virtual Linux Plumbers Conference and it's still looking like it will happen, it's just a matter of when the initial infrastructure will be in place and how slowly the rollout will be.

Back in July, Linus Torvalds shared his thoughts on Rust within the Linux kernel tree and didn't shoot down the idea just his preference on how it be handled, basically having it be enabled if Rust is present on the system.

There's something special about maps. I remember opening the front book cover of JRR Tolkien's The Hobbit when I was younger, staring at the hand-drawn map of Middle Earth, and feeling the wealth of possibility contained in the simple drawing. Aside from their obvious purpose of actually describing where things are in relation to other things, I think maps do a great job of expressing potential.

    The day has finally come that Mesa's classic OpenGL drivers (non-Gallium3D) have been cleared out of the code-base as part of their modernization effort for mainline. After a half-year pending, the "Delete Mesa Classic" merge request was honored today in eliminating the Mesa "classic" OpenGL drivers from the code-base. The drivers will still be maintained in an "Amber" branch, but considering how little focus these drivers have been receiving by upstream Mesa developers currently, don't expect much (or, if any) real changes moving ahead.

  • Steam support for Chromebooks could surface this week

    After months and months and even more months of waiting, it appears that we may finally get our first look at native Steam gaming on Chrome OS in the very near future. Affectionately known as project ‘Borealis’, the containerized version of Steam has been in the works for nearly two years and it was initially thought that Google was targeting mid to late 2022 for a release. With Chrome OS 96 just rolling out and the next iteration of Google’s desktop operating system not due until January of 2022, it’s fairly clear that this target was missed but that’s okay. I’d rather see a fully baked product released than a buggy piece of software that sours users to Chrome OS. Anyway, in its early development, I presumed that ‘Borealis’, a.k.a. Steam on Chrome OS, would simply be an optimized version of the Steam application that would install and run inside the current Linux container. Over time, we learned that Google was actually creating an entirely new container designed specifically to house Borealis and that it should run independently from the Debian container currently available in Stable Chrome OS. This makes more sense as Google can retain control of the Borealis container and keep it neat and clean for running Steam. Presumably, users will never actually interact with the container like you can with the Linux terminal.
