  • The State Of Debian & Fedora On The RISC-V Architecture

    RISC-V remains of a lot of interest to open-source/Linux users for being a royalty-free and completely open CPU architecture. In part due to the lack of affordable RISC-V hardware limiting developers from working more on this architecture, the state of RISC-V support by Linux distributions varies but at least has improved a lot in recent years.

    At this past weekend's FOSDEM 2019 conference was a RISC-V track with several interesting talks about this open processor ISA and various software efforts around it.

  • Best Raspberry Pi cases: Great options to dress up your mini-PC

    You don't have to buy a case for a Raspberry Pi, but doing so makes the experience that much nicer. That's particularly so if, for example, you plan to use a Pi 3 B+ as a home-theater PC or even a secondary desktop.

    A whole sea of options exist out there, though, ranging from simple acrylic cases to elaborately carved wood shells. So we dug into the mix to find the best of the bunch at different prices—and came up with a selection that should make minimalists, HTPC fans, gamers, hardware hackers, and even hot-rod enthusiasts happy.

  • Embedded in San Diego

    Starting tomorrow, Collabora will be exhibiting & speaking at Embedded Linux Conference North America (ELCNA) in San Diego, California. Co-located with the Open Source Summit North America, ELCNA is the premier vendor-neutral technical conference for companies and developers using embedded Linux. If you are planning on attending either conference, make sure to stop by our booth to see what our team has been working on! This year, we'll be showcasing how Panfrost, the open source driver for Arm Mali GPUs, turns a RK3399 SoC (in this case, the versatile ROCK Pi 4), into a very attractive platform to try out Wayland on ARM devices.

  • Amazon DocumentDB Speeds Up With Slow Queries Logging

    Amazon continues to add extra supports to its non-relational database store DocumentDB with the addition of slow queries logging. Slow queries logging allows user to monitor their slowest queries in the cluster. This helps to improve overall performance of the cluster and the individual query. Once the user has enabled a set profiler for the query the system will monitor operations and if any queries run longer than the customer-defined threshold, set at 100ms by default, the system will log their execution time and send an alert to the CloudWatch Logs.

Security: Sphinx, Ransomware, Webmin, YubiKey

  • Exposed Sphinx Servers Are No Challenge for Hackers [Ed: That’s the same agency and the same troll site that initially promoted the lies and the FUD about VLC]

    A popular open-source text search server, Sphinx offers impressive performance for indexing and searching data in databases or just in files. It is cross-platform, available for Linux, Windows, macOS, Solaris, FreeBSD, and a few other operating systems. [...] CERT-Bund posted the warning on Twitter today alerting network operators and providers about the risk of running Sphinx servers with a default configuration that are open on the web. The organization highlights that Sphinx lacks any authentication mechanisms. Exposing it on the web gives an attacker the possibility "to read, modify or delete any data stored in the Sphinx database."

  • Ransomware Hits Texas Local Governments [iophk: Windows TCO]

    The attack was observed on the morning of August 16 and appears to have been launched by a single threat actor, the DIR announcement reads.

    The State Operations Center (SOC) was activated soon after the attack reports started to come in, and DIR says that all of the entities that were actually or potentially affected appear to have been identified and notified.

    A total of twenty-three entities have been confirmed as impacted so far, and the responders are working on bringing the affected systems back online.

  • Webmin Backdoored for Over a Year

    The security hole impacts Webmin 1.882 through 1.921, but most versions are not vulnerable in their default configuration as the affected feature is not enabled by default. Version 1.890 is affected in the default configuration. The issue has been addressed with the release of Webmin 1.930 and Usermin version 1.780.

  • The YubiKey 5Ci is the 'first' iOS-compatible security key

    Like other YubiKey options in the 5 series, the YubiKey 5Ci supports multiple authentication protocols, including IDO2/WebAuthn, FIDO U2F, OTP (one-time-password), PIV (Smart Card), and OpenPGP.
