    You can now buy Orange Pi Zero LTS Arm Linux SBC for $8.49 and up. The tiny board is ideal for headless applications with WiFI and Ethernet connectivity.

  • Toughened up embedded PC can run 8th or 9th Gen Coffee Lake CPUs

    Avalue’s rugged “EPS-CFS” computer runs Linux or Win 10 on Intel 8th or 9th Gen Coffee Lake CPUs up to an octa-core Core i7-9700TE, and supplies up to 32GB GB DDR4, 2x SATA bays, 2x GbE, 2x HDMI, and 4x USB 3.2 ports.

    Avalue announced an embedded computer with Intel’s 8th Gen Coffee Lake T-series or the new, but similarly 14nm-fabricated, 9th Gen Coffee Lake Refresh TE-series chips. The EPS-CFS computer, which is built around Avalue’s 3.5-inch ECM-CFS SBC, joins other 9th Gen-ready products including Kontron’s COMe-cWL6 (E2S) and Congatec’s Conga-TS370 COM Express modules.

  • RTL-SDR: Seven Years Later

    When I wrote that article in 2012, the RTL-SDR project and its community were still in their infancy. It took some real digging to find out which TV tuners based on the Realtek RTL2832U were supported, what adapters you needed to connect more capable antennas, and how to compile all the software necessary to get them listening outside of their advertised frequency range. It wasn’t exactly the most user-friendly experience, and when it was all said and done, you were left largely to your own devices. If you didn’t know how to create your own receivers in GNU Radio, there wasn’t a whole lot you could do other than eavesdrop on hams or tune into local FM broadcasts.

    Nearly a decade later, things have changed dramatically. The RTL-SDR hardware and software has itself improved enormously, but perhaps more importantly, the success of the project has kicked off something of a revolution in the software defined radio (SDR) world. Prior to 2012, SDRs were certainly not unobtainable, but they were considerably more expensive. Back then, the most comparable device on the market would have been the FUNcube dongle, a nearly $200 USD receiver that was actually designed for receiving data from CubeSats. Anything cheaper than that was likely to be a kit, and often operated within a narrower range of frequencies.

Leftovers: Kate, Krita, UCLA Library and RcppExamples

  • Kate - Document Preview Plugin - Maintainer Wanted!

    At the moment the Document Preview plugin that e.g. allows to preview Markdown or other documents layout-ed via embedding a matching KPart is no longer maintained. If you want to step up and keep that plugin alive and kicking, now is your chance!

  • The Sprint

    Hi -)) haven’t posted for some time, because I was busy travelling and coding for the first half of the month. From Aug 5 to Aug 9, I went to the Krita Sprint in Deventer, Netherlands. According to Boud, I was the first person to arrive. My flight took a transit via Hong Kong where some flights were affected due to natural and social factors, but fortunately mine was not one of them. Upon arrival in Amsterdam I got a ticket for the Intercity to Deventer. Railway constructions made me take a transfer via Utrecht Centraal, but that was not a problem at all: the station has escalators going both up to the hall, and down to the platforms (in China you can only go to the hall by stairs or elevator (which is often crowded after you get off)). When I got out of Deventer Station, Boud immediately recognized me (how?!). It was early in the morning, and the street’s quietness was broken by the sound of me dragging my suitcase. Boud led me through Deventer’s crooked streets and alleys to his house. For the next two days people gradually arrived. I met my main mentor Dmitry (magician!) and his tiger, Sagoskatt, which I (and many others) have mistaken for a giraffe. He was even the voice actor for Sago. He had got quite a lot of insights into the code base (according to Boud, “80%”) and solved a number of bugs in Krita (but he said he introduced a lot of bugs, ha!). Also I met David Revoy (my favourite painter!), the author of Pepper and Carrot. And Tiar, our developer who started to work full-time on Krita this year; she had always been volunteering to support other Krita users and always on the IRC and Reddit. And two of other three GSoC students for the year: Blackbeard (just as his face) and Hellozee. Sh_zam could not come and lost communications due to political issues, which was really unfortunate (eh at least now he can be connected). It is feels so good to be able to see so many people in the community – they are so nice! And it is such an experience to hack in a basement church.

  • How UCLA Library preserves rare objects with open source

    The University of California, Los Angeles, (UCLA) Library houses a collection of millions of rare and unique objects, including materials dating from 3000 BCE, that could be damaged, destroyed, or otherwise threatened if they were displayed. To make these special collections widely available while keeping them secure, the UCLA Library has been modernizing its digital repository, which was established 15 years ago on now-outdated software. [...] Watch Jen's Lightning Talk to learn more about the UCLA Library's rare collections digitization project.

Servers: Ampere Computing, SUSE and Red Hat

  • Ampere Computing Is Keeping Close Track Of The Linux Performance For Their ARM Servers

    Hardware vendor Ampere Computing with their impressive ARM servers is doing a great job on closely following their hardware's Linux performance as part of a rigorous continuous testing regiment or ensuring quality, compatibility, and stability while being fully-automated. Ampere Computing's Travis Lazar talked at this week's Linux Foundation events in San Diego over the importance of continuous regression testing for software and hardware development by talking about their internal workflow and software in place. Their internal system is the "Totally Automated Regression System" or TARS for short. TARS makes use of various open-source components including the Phoronix Test Suite and its vast collection of benchmarks for providing comprehensive test coverage plus Ampere's own "extensions" to the Phoronix Test Suite. TARS also incorporates the provisioning/configuration responsibilities as well as analysis of the data.

  • From ProdOps to DevOps: Surviving and thriving

    For many of us in Production Operations (ProdOps), change is the enemy. If something changes, there is now an opportunity for things that were working just fine to experience problems. It is like a game of Jenga. When will the tower fall because a seemingly minor change unbalances the whole stack of pieces? ProdOps teams hate change so much, that countless frameworks have been invented to "manage" changes; in reality, these frameworks make the procedure for effecting a change so onerous that most people give up and accept the status quo. Actually, that statement is a bit unfair. These frameworks are an attempt to wrap planning and consensus around production changes, thus minimizing potential downtime caused by random or rogue changes (see Why the lone wolf mentality is a sysadmin mistake).

  • Meet Red Hat at VMworld

    As Red Hat’s Ashesh Badani said in his blog post about the reference architecture for OpenShift on VMware’s SDDC stack “… this is just the first step — Red Hat OpenShift 4 brings optimized installation capabilities to a variety of infrastructures and for this, the companies are working towards a VMware Validated Design. We are excited that VMware is working closely with Red Hat to deliver a simplified experience there in the coming months.”
