  • Wasmer 0.16 Released For Running WebAssembly Programs Anywhere

    Wasmer 0.16 is released as the newest version of this "universal WebAssembly runtime" for running WebAssembly programs on the desktop that could in turn be written in a number of different programming languages.

    Wasmer is one of the leading efforts for providing a WebAssembly run-time on the desktop and leading to great code portability and performance everywhere. Meanwhile Intel, Red Hat, Mozilla, and others continue investing in Wasmtime as a JIT-focused WebAssembly run-time.

  • One year of Mergify

    It has been close to a year now that I've incorporated my new company, Mergify. I've been busy, and I barely wrote anything about it so far. Now is an excellent time to take a break and reflect a bit on what happened during those last 12 months.

  • Make SSL certs easy with k3s

    Traefik (which comes pre-bundled with k3s) actually has Let's Encrypt support built-in, so you may be wondering why we are installing a third-party package to do the same thing. At the time of this writing, Traefik's Let's Encrypt support retrieves certificates and stores them in files. Cert-manager retrieves certificates and stores them in Kubernetes secrets. Secrets can be simply referenced by name and, therefore, easier to use, in my opinion. That is the main reason we are going to use cert-manager in this article.

  • Need a fast way to tag faces in many images? Try Imaginario!

    Today I've released Imaginario 0.9. The big feature coming with this new release is a face tagging flow which I believe will be the fastest and simplest you've ever used, despite it being all manual. I even sat down and spent some quality time with Blender to prepare a video to show it off:

    dav1d 0.6.0 'Gyrfalcon', the fast and lean AV1 decoder
    This is a major update of the dav1d, the fast and lean AV1 decoder,
    codename 'Gyrfalcon'.
    0.6.0 brings major improvements in 10/12bit decoding on ARMv8 CPUs,
    up to 2.5 times faster than 0.5.2.
    It also brings new AVX-512, AVX2 and SSSE3 optimizations and improves
    the existing optimizations on all platforms.
    Finally, it also fixes some decoder mismatches and minor crashes.
  • Dav1d 0.6 AV1 Video Decoder Delivering Healthy Improvements For Intel + AMD Processors

    Given this week's release of dav1d 0.6, here are some fresh benchmarks of this open-source AV1 video decoder on a few different Intel and AMD systems so far.

    Dav1d 0.6 has various AVX2 and AVX-512 optimizations that excite us plus 10/12-bit video decoding improvements for ARMv8 hardware. With waiting for some more exciting ARM server platforms still to arrive, this round of testing is just looking at the Intel/AMD x86_64 CPU performance.

  • VideoLAN's dav1d 0.6 Released With More AVX2 + AVX-512 Optimizations

    Dav1d 0.6 is now available as a big update to this open-source AV1 video decoder developed by the VideoLAN crew.

    Dav1d already is quite fast on most CPUs but now is even faster on x86_64 hardware thanks to enabling AVX-512 optimizations and also extending their AVX2 and SSSE3 optimizations.

gThumb 3.9.1 Released with Various Changes, New App Icon

Filed under

A new stable release of gThumb, the GTK-based photo manager and image viewer for Linux desktops, is now available to download.

I wrote about how to install gThumb on Ubuntu a couple of months back and figured that the latest update may be of interest to those of you who use it!

gThumb 3.9.1 isn’t a game-changing release, but it touts a number of notable enhancements, bug fixes, and feature tweaks. It even has a spiffy new app icon (right) designed according to the new GNOME icons style.

Elsewhere, the photo management app now lets you customise keyboard shortcuts to suit your tastes, and adds a shortcuts “cheat sheet”.

Users can press ctrl + f1 with the app in focus to reveal it. This is part of a wider GNOME initiative to make keyboard shortcuts more discoverable among GTK applications.

FocusWriter - Text editor gone minimalistic

Filed under

A few weeks ago, I was looking around for some nice Linux software, and I came across the home page of the person who had created the Whisker Menu for Xfce. Since I really like this one - I even included it as my favorite desktop menu in the 2018 best Linux apps compilation, I was intrigued by the other software in the repertoire, and decided to do some random testing. A program called FocusWriter drew my attention.

Well, FocusWriter is meant to be a simple, straightforward, distraction-free advanced text editor, designed to provide those using it with maximum productivity. In other words, you don't waste time managing the software, you don't waste time getting your fleeting attention span diverted, you get stuff done. Well, that's the core idea on paper. As someone who writes books, I found the concept curious and inviting. Perhaps I could be doing something more effectively? Well, let's find out.

Voting and Petitioning With Proprietary Software

Filed under
  • Voters struggled with LA’s fancy new voting machines on Super Tuesday

    Jennifer Cohn, an attorney and election integrity advocate, aggregated at least 100 social media or news reports related to the new voting system. They’re all bad.


    It’s all supposed to be high tech, but the system has been showing some low-tech flaws since it debuted earlier this year. In late February, during California’s early voting period, CBS reported that some of the new voting machines were going unused because of issues with equipment, and that about 30 out of 229 total locations didn’t open on time because of issues with the tech.

  • On Super Tuesday, America's voting technology will be under intense scrutiny

    While election technology will continue to evolve to meet new threats, Heikki Nousiainen, CTO of the open-source technology company Aiven, said that companies hoping to safeguard the process will always have to split the difference between verifying a vote and protecting the voter's anonymity. He suggested that an open-source model could help achieve this.

  • Boulder makes strides toward online petitions for 2021 election

    Council, on the whole, agreed that open-source may not be the way to go for elections-related systems. (Open-source software was not a criteria in the Request for Proposals.)

    “With elections stuff, you want to move slowly and include a lot of security,” said councilman Aaron Brockett, a software industry professional “I think we’re on the right path.”

    Two council members, Adam Swetlik and Rachel Friend, wanted to issue a new RFP, due to what they saw as a lack of transparency during the lass process. City leaders convened what Carr called a “courtesy” meeting of the disbanded Campaign Finance/Elections Working Group to update them on the process and gather input.

  • Boulder Council minority skeptical of online petitioning system’s development process

    MapLight produced two “open source” systems, in which the programming code for the petitioning software can be accessed by the public and scrutinized and updated, but those were built outside the formal city bidding process. When MapLight responded to the city’s request, the offer was not for free development, according to a city staff memo to the council.

Software: TenFourFox, Qt 4, MetaInfo Creator

Filed under
  • TenFourFox FPR20 available

    TenFourFox Feature Parity Release 20 final is now available for testing (downloads, hashes, release notes). This version is the same as the beta except for one more tweak to fix the preferences for those who prefer to suppress Reader mode. Assuming no issues, it will go live Monday evening Pacific as usual.
    I have some ideas for FPR21, including further updates to Reader mode, AltiVec acceleration for GCM (improving TLS throughput) and backporting later improvements to 0RTT, but because of a higher than usual workload it is possible development may be stalled and the next release will simply be an SPR. More on that once I get a better idea of the timeframes necessary.

  • The day has finally arrived: Qt 4 is no longer part of Debian unstable. It's gone.

    Thanks should go to many people. You know who you are, and I really appreciate the support and time you put into this. **Thanks**

  • Matthias Klumpp: Introducing the MetaInfo Creator

    This blog post however is not about that. It’s about what I learned when talking to people there about AppStream, and the outcome of that. Especially when talking to application authors but also to people who deal with larger software repositories, it became apparent that many app authors don’t really want to deal with the extra effort of writing metadata at all. This was a bit of a surprise to me, as I thought that there would be a strong interest for application authors to make their apps look as good as possible in software catalogs.

    A bit less surprising was the fact that people apparently don’t enjoy reading a large specification, reading a long-ish intro guide with lots of dos and don’ts or basically reading any longer text at all before being able to create an AppStream MetaInfo/AppData file describing their software.

    Another common problem seems to be that people don’t immediately know what a “reverse-DNS ID” is, the format AppStream uses for uniquely identifying each software component. So naturally, people either have to read about it again (bah, reading!

Cockpit - Highway to the admin zone

Filed under

Cockpit seems like a very handy project. It's elegant, robust and comes with a clean interface and readily usable defaults, which place it ahead of most similar programs of its nature. Sure, in the long run, you can't cheat physics. The second law of thermodynamics does require that you have expert knowledge and be able to fully understand and control the gory details behind the scene. But in the critical adoption period, between setup and first use, Cockpit does not ask for your kidney and soul right away.

The real power of Cockpit will surely be in the domain of enterprise, cloud and other buzzwordly places, but even as a home user, you can benefit from it. If you have several Linux machines, and you want to be have a quick glance at their behavior, or do some basic management, Cockpit offers a fuss-free way plus a Web interface, which means you really are portable when it comes to everyday usage. I'm quite intrigued and happy, and I'm looking forward to see how this project evolves. Recommended, so you might as well go about testing. The end.

  • Get Google Drive Integration on Ubuntu (Linux) with Insync

    Insync is a great app for Ubuntu that lets you integrate your Google Drive to Ubuntu. Not just that, you can also sync multiple Google Drive accounts.

    Some years ago Gmail wasn’t as popular as it is today, neither was Google Drive and many other Google services. Thanks to the massive success of Android though, these services had a great ride to success themselves. Most of us have an Android device and most of them do come pre-installed with Google Drive already. Anyone who’s not already using another cloud service will find it easier to just use Google Drive. It also provides PC clients for Mac and Windows so your files are available across all your devices. On Linux (and thus, Ubuntu) though, using Google Drive is not a great experience. But it can be if you are ready to shell out a few bucks for Insync.

Top 5 VirtualBox Alternatives for Linux

Filed under

VirtualBox is one of the most popular virtualization programs out there. It comes packed with a lot of powerful features and is a free open source program under the GNU General Public License. But while VirtualBox is fantastic, it isn’t the only virtual machine option out there. Anyone who’s looking for something different should check out these top 5 VirtualBox alternatives for Linux.

Virtual machine software or virtualization is a popular way for businesses and individual users to run different operating systems on their hardware. Many companies use virtualization to save money by being able to run and test different systems on a single computer. The technology is as useful for those at home. For example, people like to use virtualization to test out new software without corrupting the system.

But you can’t install every virtualization program on every operating system (host system). Some of the options listed here aren’t only for Linux. You can run them on macOS or PCs with Windows systems installed as well. But all the options mentioned below will definitely work on Linux.
