  • Civil Infrastructure Platform Takes Open Source to an Industrial Scale

    One of the less discussed uses for open source software is actually in the role that it plays for industrial-scale hardware. Whereas power plants, factories, and other large infrastructure projects were once ruled over nearly entirely by operational technology (OT) control systems, in recent years, information technology — built on open source software — has been making its way onto the scene in an increasingly significant way.

    Additionally, another surprising fact is that the this push to use open source in complex hardware operations has been embraced by industry leaders. One company helping to lead the charge is Siemens, one of the world’s largest producers of hardware devices, Siemens. Siemens plays an active role in advancing open source in the industrial space, with a focus on making open source security a priority for development, in part through their involvement in the Civil Infrastructure Platform (CIP) initiative.

  • Final Directive is a surprisingly good shooter, we have a copy to give away

    Final Directive is a pretty good shooter that released for Linux back in February and we have a copy to give away.

    And we’re going to release the Mac and Linux versions as soon as we can.

  • [Krita] Interview with Runend

    I have tried some of the features, especially the brush engine, UI/UX, layering, animation tools, I love all of them! And of course it’s free and open source.

  • Free software log (March 2018)

    I did get a few software releases out this month, although not as much as I'd planned and I still have a lot of new releases pending that are waiting for me to have a bit more free time.

    control-archive got a 1.8.0 release, which catches up from accumulated changes over the past year plus and falls back to GnuPG v1 for signature processing. One of the projects that I'd like to find time for is redoing all of my scattered code for making and checking Usenet control messages.

  • Update desktop components for released version
  • Building my ideal router for $50

    After my Asus N66U kicked the bucket, I considered a few options: another all-in-one router, upgrade to something like an EdgeRouter, or brew something custom. When I read the Ars Technica article espousing the virtues of building your own router, that pretty much settled it: DIY it is.

    I’ve got somewhat of a psychological complex when it comes to rolling my own over-engineered solutions, but I did set some general goals: the end result should be cheap, low-power, well-supported by Linux, and extensible. Incidentally, ARM boards fit many of these requirements, and some like the Raspberry Pi have stirred up so much community activity that there’s great support for the ARM platform, even though it may feel foreign from x86.

    I’ve managed to cobble together a device that is not only dirt cheap for what it does, but is extremely capable in its own right. If you have any interest in building your own home router, I’ll demonstrate here that doing so is not only feasible, but relatively easy to do and offers a huge amount of utility - from traffic shaping, to netflow monitoring, to dynamic DNS.

    I built it using the espressobin, Arch Linux Arm, and Shorewall.

Essential System Tools: QDirStat – Excellent Qt-based directory statistics

This is the latest in our series of articles highlighting essential system tools. These are small, indispensable utilities, useful for system administrators as well as regular users of Linux based systems. The series examines both graphical and text based open source utilities. For this article, we’ll look at QDirStat, a graphical application to show what’s devouring your disk space and help you tidy up the disorder. For details of all tools in this series, please check the table at the summary page of this article. QDirStat is a continuation of the KDirStat utility. QDirStat is based on the latest Qt 5, and doesn’t need any KDE libraries or infrastructure. If you come from a Windows background you’ve probably tried WinDirStat, a Windows port of KDirStat, the predecessor of QDirStat. Read more

KDE is adding Matrix to its instant messaging infrastructure

KDE has been looking for a better way of chatting and live-sharing information for several years now. IRC has been a good solution for a long time, but it has centralized servers KDE cannot control. It is also insecure and lacks features users have come to expect from more modern IM services. Other alternatives, such as Telegram, Slack and Discord, although feature-rich, are centralized and built around closed-source technologies and offer even less control than IRC. This flies in the face of KDE's principles that require we use and support technologies based on Free software. However, our search for a better solution has finally come to an end: as of today we are officially using Matrix for collaboration within KDE! Matrix is an open protocol and network for decentralised communication, backed by an open standard and open source reference implementations for servers, clients, client SDKs, bridges, bots and more. It provides all the features you’d expect from a modern chat system: infinite scrollback, file transfer, typing notifications, read receipts, presence, search, push notifications, stickers, VoIP calling and conferencing, etc. It even provides end-to-end encryption (based on Signal’s double ratchet algorithm) for when you want some privacy.

Canonical Is Planning Some Awesome New Content For The Snap Store

There I was, thoughtfully drafting an article titled "3 Things Canonical Can Do To Improve The Snap Ecosystem," when I jumped on the phone with Evan Dandrea, an Engineering Manager who just so happens to be responsible for the Snapcraft ecosystem at Canonical. As it turns out, that headline will need a slight edit. One less number. That's because I've just learned Canonical has some ambitious plans for the future of the Snap Store. Read more
