  • A masterclass in over-engineering

    Twitter went wild for the Robot Arm Clock featured in the new issue of The MagPi. At the last count our tweet had 1.8K retweets.

    We also showed you how to make Dune’s Gom Jabbar test, and we enjoyed a little Chopin as we watched a piano control LED lights.

  • Converting a Fat Cat cushion into a controller for Final Fantasy XIV | Arduino Blog

    Mounts in the video game Final Fantasy XIV act like how cars or horses do in our world since they allow players to travel around the map much faster than would otherwise be possible. But even better, mounts are ways to express personality and have some fun, which is especially evident with the infamous “Fatter Cat” mount, as it got so widely beloved that Square Enix, the game’s publisher, decided to start selling a plushie version of it in their store.

  • Unsurv offline open source, privacy friendly GNSS receiver with ESP32 & NFC

    “unsurv offline is a privacy friendly, small and lightweight PCB based on an ESP32 featuring a high quality GNSS receiver, accelerometer, and NFC capabilities. Using a combination of onboard features and OpenStreetMap (OSM) data, unsurv offline helps you collect and analyze location data in a privacy-friendly way. Originally conceived to better understand offline video surveillance, this fully open source project is here to help you find and develop a variety of custom use cases.”

Databases: MongoDB/NoSQL, Firebird, and Rqlite/SQLite

  • Top 10 features of MongoDB Atlas | FOSS Linux

    MongoDB is a NoSQL general-purpose document-oriented database that is free to use. It is a scalable, versatile NoSQL document database platform built to overcome the constraints of previous NoSQL solutions and the approach of relational databases. It helps the user store and deals with an enormous amount of data. MongoDB’s horizontal scaling and load balancing capabilities have given application developers unprecedented flexibility and scalability. There are different MongoDB editions; however, we will focus on MongoDB Atlas in this article. MongoDB Atlas is a multi-cloud database service created by the MongoDB team. Atlas makes it easy to deploy and manage databases while also giving users the flexibility they need to develop scalable, high-performance global applications on the cloud providers of their choice. It is the world’s most popular cloud database for modern applications. Developers can use Atlas to deploy fully managed cloud databases on AWS, Azure, or Google Cloud. Developers can relax easily knowing that they have rapid access to the availability, scalability, and compliance they need for enterprise-level application development.

  • Rqlite 7.0 Released For Distributed Relational Database Built Atop SQLite - Phoronix

    Rqlite 7.0 is now available as a lightweight, distributed relational database. This open-source database system for cluster setups is built atop SQLite while aiming to be easy-to-use and fault-tolerant.

Writing an open source GPU driver – without the hardware

After six months of reverse-engineering, the new Arm “Valhall” GPUs (Mali-G57, Mali-G78) are getting free and open source Panfrost drivers. With a new compiler, driver patches, and some kernel hacking, these new GPUs are almost ready for upstream. In 2021, there were no Valhall devices running mainline Linux. While a lack of devices poses an obvious obstacle to device driver development, there is no better time to write drivers than before hardware reaches end-users. Developing and distributing production-quality drivers takes time, and we don’t want users to be reliant on closed source blobs. If development doesn’t start until a device hits shelves, that device could reach “end-of-life” by the time there are mature open drivers. But with a head start, we can have drivers ready by the time devices reach end users. Let’s see how.

Security Leftovers

  • CVE-2021-4034 – Ariadne's Space

    Before we get into this, I have seen a lot of people on Twitter blaming systemd for this vulnerability. It should be clarified that systemd has basically nothing to do with polkit, and has nothing at all to do with this vulnerability, systemd and polkit are separate projects largely maintained by different people. We should try to be empathetic toward software maintainers, including those from systemd and polkit, so writing inflammatory posts blaming systemd or its maintainers for polkit does not really help to fix the problems that made this a useful security vulnerability.

  • Windows ransomware LockBit makes the jump to Linux [Ed: Pro-Windows site. Misses the point that over 90% of ransomware is a Windows problem.]

    First, they came for Windows. Then, for Tux. As cool as Linux is, it's increasingly becoming a target for ransomware-friendly cyber criminals intent on ruining people's days.

  • These critical security bugs put Linux servers at risk of attack [Ed: Attack from the inside maybe; you need to actually have an account on such machines to begin with... compare to Windows with remotely-exploitable full compromise bugs/back doors]
  • Patch Now: A newly discovered critical Linux vulnerability probably affects your systems
  • IoT security certification group gains steam [Ed: Another fake security consortium? Their shoddy products might be best off avoided altogether, as there's rarely a practical need for such gimmicks.]

    The ioXT Alliance, which offers a certification program for IoT security, announced it has certified 195 products and grown to 580 members. Meanwhile, Timesys is seeking participants for a survey on IoT security.
