  • 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.

  • 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.

Why Everyone should know vim

Vim is an improved version of Vi, a known text editor available by default in UNIX distributions. Another alternative for modal editors is Emacs but they’re so different that I kind of feel they serve different purposes. Both are great, regardless. I don’t feel vim is necessarily a geeky kind of taste or not. Vim introduced modal editing to me and that has changed my life, really. If you have ever tried vim, you may have noticed you have to press “I” or “A” (lower case) to start writing (note: I’m aware there are more ways to start editing but the purpose is not to cover Vim’s functionalities.). The fun part starts once you realize you can associate Insert and Append commands to something. And then editing text is like thinking of what you want the computer to show on the computer instead of struggling where you at before writing. The same goes for other commands which are easily converted to mnemonics and this is what helped getting comfortable with Vim. Note that Emacs does not have this kind of keybindings but they do have a Vim-like mode - Evil (Extensive Vi Layer). More often than not, I just need to think of what I want to accomplish and type the first letters. Like Replace, Visual, Delete, and so on. It is a modal editor after all, meaning it has modes for everything. This is also what increases my productivity when writing files. I just think of my intentions and Vim does the things for me.

  • Mesa 18.1-RC1 Released With The Latest Open-Source 3D Driver Features
    Seemingly flying under our radar is that Mesa 18.1 has already been branched and the first release candidate issued. While the Mesa website hasn't yet been updated for the 18.1 details, Dylan Baker appears to be the release manager for the 18.1 series -- the second quarter of 2018 release stream.

Exploring Contributors Centrality Over Time

At the end of my previous post we concluded with yet another question. Indeed, on the 2017 KDEPIM contributor network we found out that Christian Mollekopf while being a very consistent committer didn't appear as centrality as we would expect. Yet from the topology he seemed to act as a bridge between the core contributors and contributors with a very low centrality. This time we'll try to look into this and figure out what might be going on. My first attempt at this was to try to look into the contributor network on a different time period and see how it goes. If we take two snapshots of the network for the two semesters of 2017, how would it look? Well, easy to do with my current scripts so let's see! Read more
