  • Time for school as the big Cities: Skylines - Campus expansion is out now

    Paradox Interactive and Colossal Order have put school back on the map, as the Cities: Skylines - Campus expansion is out now. In terms of features and new content, this is one of the bigger expansions to be released.

    Adding in a little extra complexity for those who want it while also giving you even more freedom at the same time with the way you design your campus. Much like what came with the Parklife expansion, Campus lets you freely zone an entire area to build your fancy new education system.

    Here's something to keep you going for a little while, the Humble tinyBuild Bundle 2019 went live today and it has plenty of Linux games.

  • Academic Support Center BiASC connects the SUSE Academic Program with Belgium and Luxembourg

    The SUSE Academic Program has taken significant strides in new territories with the help of trusted academic partners from different regions. BiASC is an academic support organization that connects with IT academies from higher and secondary education and from non-commercial and professional training institutions. Already working with a number of universities, including the University of Luxembourg and Katholieke Universiteit Leuven, we hope to see our footprint spread with support from BiASC.

  • Raspberry Pi Close To Seeing CPUFreq Support

    Nicolas Saenz Julienne of SUSE has been working on CPUFreq support for the Raspberry Pi single board computers to allow for the Linux kernel to provide CPU frequency scaling controls.

    This CPUFreq support communicates with firmware running on a dedicated processor on the Raspberry Pi that is responsible for adjusting the CPU frequencies as well as that of the VPU and related blocks. The driver can request changes to the CPU frequencies though isn't necessarily honored depending upon thermal factors and other criteria. The firmware also offers the ability to request a turbo mode, but that can boost up other clocks and appears to be causing issues at least with the current state of the Raspberry Pi kernel drivers.

  • Freexian’s report about Debian Long Term Support, April 2019

  • RC candidate of the day (1)

    Sometimes the list of release-critical bugs is overwhelming, and it’s hard to find something to tackle.

    So I invite you to have a go at #928040, which may only be a case of reviewing and uploading the included patch.

  • [GSoC – 1] Achieving consistency between SDDM and Plasma

    I’m very excited to start off the Google Summer of Code blogging experience regarding the project I’m doing with my KDE mentors David Edmundson and Nate Graham.

    What we’ll be trying to achieve this summer is have SDDM be more in sync with the Plasma desktop.

    What does that mean? The essence of the problem is quite simple: you can customize Plasma to no end, yet the only thing you can customize in SDDM is the cursor theme. As a customization-loving user, this has been a big pet peeve of mine. In my attempts to work around the issue I’ve already went as far as adding one too many config points to the Breeze SDDM theme. So to finish that project and thereby solve our GSoC issue, perhaps we could just hook up the respective KCM’s UI to those options…

  • Guaranteed Hard Real-time Response and Determinism from Aitech's Space SBC Processor Using NASA cFS Linux
  • Embedded PC with 6th or 7th Gen CPUs offers optional mini-PCIe and PCIe x4

    Aaeon’s barebones, semi-rugged “EPIC-KBS9-PUC” embedded PC runs on 6th or 7th Gen Core CPUs with up to 4x GbE and 2x serial plus 4x USB, mSATA, dual displays, and optional mini-PCIe, PCIe x4, or 2.5-inch HDD.

    Aaeon has spun last year’s EPIC form-factor EPIC-KBS board into an embedded system for light industrial duty including “automated warehouse robots, retail POS systems, and even a 3D printer for cakes.” The barebones, 216 x 180 x 65mm system will presumably let you load either Linux or Windows on a range of 6th (Skylake) or 7th (Kaby Lake) generation Intel Core CPUs up to 65W.

  • Apple Is Finally Fixing the Keyboards on MacBook Pros

    Apple’s newest MacBook Pros, which are being announced today and include significant bumps in power and performance, are still using Apple’s third-generation “butterfly” keyboard. But the company says these keyboards have a change in the physical material that exists within the butterfly mechanism that will address some of the issues that MacBook users have been experiencing. The company declined to say exactly what the material change was. [...]

  • Flex PCB Fabrication

    I’ve gotten a few people asking me where I get my flex PCBs fabricated, so I figured I’d make a note here. I get my flex PCBs (and actually most of my PCBs, except laser-drilled microvia) done at a medium-sized shop in China called King Credie. Previously it was a bit hard to talk about them because they only took orders via e-mail and in Chinese, but they recently opened an English-friendly online website for quotation and order placement. There’s still a few wrinkles in the website, but for a company whose specialty is decidedly not “web services” and with English as a second language, it’s usable.

    Knowing your PCB vendor is advantageous for a boutique hardware system integrators like me. It’s a bit like the whole farm-to-table movement — you get better results when you know where your materials are coming from. I’ve probably been working with King Credie for almost a decade now, and I try to visit their facility and have drinks with the owner on a regular basis. I really like their CEO, he’s been a circuit board fabrication nerd since college, and he’s living his dream of building his own factory and learning all he can about interesting and boutique PCB processes.

  • TechnicalDebt

     

    Thinking of this as paying interest versus paying of principal can help decide which cruft to tackle. If I have a terrible area of the code base, one that's a nightmare to change, it's not a problem if I don't have to modify it. I only trigger an interest payment when I have to work with that part of the software (this is a place where the metaphor breaks down, since financial interest payments are triggered by the passage of time). So crufty but stable areas of code can be left alone. In contrast, areas of high activity need a zero-tolerance attitude to cruft, because the interest payments are cripplingly high. This is especially important since cruft accumulates where developers make changes without paying attention to internal quality - the more changes, the greater risk of cruft building up.

Open Invention Network, the Linux-based patent non-aggression community, exceeds 3,000 licensees

OIN's mission is to enable Linux, its related software, and its programmers to develop and monetize without being hogtied by patent fights. In Linux's early years, this was a constant threat. Now, thanks largely to the OIN's efforts to get everyone to agree on the basic open-source principle -- that's it's better and more profitable to share than to cling to proprietary property -- open-source software has taken off in the marketplace. The OIN isn't the first to take this concept and apply it to the Unix/Linux operating system family. After Novell bought Unix from AT&T, rather than keep fighting with Berkeley Software Design Inc. (BSDO) over possible Unix IP rights violations in BSD/OS, an early, commercial BSD Unix, Noorda famously declared that he'd rather compete in the marketplace than in court. This Unix case was settled in 1994. That was a one off. The OIN, which has grown by 50% in the last two years, has turned patent non-aggression into policy for thousands of companies. By agreeing to the OIN license, members gain access to patented inventions worth hundreds of millions of dollars while promoting a favorable environment for Linux and related open source software.

  • SUSE & SAP “A 20 years of Partnership”
  • SUSE on the IO500 List for HPC Storage
    If you haven’t been hanging around the Ceph world for a bit, you may not realize that Ceph was originally intended to provide a distributed file-system to service HPC clusters.  While this was the original intent, Ceph has taken a round-a-bout path to relevance in this space, especially given that we are only supporting multiple active MDS servers since the Luminous release.  The result is that we are, only now, really starting to see adoption in the HPC space, and mostly for the second tier storage needs. Enter, the science project.  Given an all-flash environment on SATA SSDS with a fast storage pool on Intel Optane for the metadata, would it be possible to provide a reasonable storage environment for HPC clusters?
