  • Imagination introduces Catapult RISC-V CPU cores - CNX Software

    As expected, Imagination Technologies is giving another try to the CPU IP market with the Catapult RISC-V CPU cores following their previous unsuccessful attempt with the MIPS architecture, notably the Aptiv family.

    Catapult RISC-V CPUs are/will be available in four distinct families for dynamic microcontrollers, real-time embedded CPUs, high-performance application CPUs, and functionally safe automotive CPUs.

  • AS5600 support for moteus auxiliary encoders

    The initial implementation of auxiliary encoders for moteus supported exactly one encoder, the AS5048B. The hardware can support any I2C based encoder, so supporting additional encoders has always been on the TODO list.

    I’m excited to announce, that as of firmware release 2021-12-03, AS5600 encoders are now supported as well. They are a lot cheaper than the AS5048 as they have a much lower update rate and resolution, but that isn’t necessarily a problem if it is only used to disambiguate a modest gear reduction.

  • Imagination launches RISC-V CPU family - Imagination

    Based on RISC-V, the open-source CPU architecture, which is transforming processor design, Imagination’s Catapult CPUs can be configured for performance, efficiency, or balanced profiles, making them suitable for a wide range of markets.

  • Imagination Announces "Catapult" RISC-V CPU Family - Phoronix

    With Imagination Technologies having sold off what was MIPS Technologies several years ago and that CPU architecture having been abandoned now, Imagination today announced "Catapult" as their new family of RISC-V processor IP.

    Imagination's Catapult is a line of RISC-V CPUs designed for heterogeneous compute and are offered in different versions to fit varying performance / efficiency needs. Catapult CPUs are also available in different families for dynamic microcontrollers, real-time embedded CPUs, high performance application CPUs, and automotive CPUs.

  • This system classifies different types of clouds using tinyML | Arduino Blog

    At the basis of each weather forecast is data — and a lot of it. And although the vast majority of atmospheric data collection is fully automated, determining cloud volumes and types are still done manually. This problem is what inspired Swapnil Verma to create a project that utilizes machine learning to categorize six different classes of clouds.

    The hardware for this system consists of an Arduino Portenta H7 due to its powerful processor and array of connectivity features, along with a Portenta Vision Shield for the camera. Both of these boards were mounted to a custom base on top of a tripod and powered by a battery bank over USB-C.

  • Steinar H. Gunderson - Speeding up Samba AD

    One Weird Trick(TM) for speeding up a slow Samba Active Directory domain controller is seemingly to leave and rejoin the domain. (If you don't have another domain controller, you'll need to join one in temporarily.) Seemingly, not only can you switch to LMDB (which has two fsyncs instead of eight on commit—which matters a lot, especially on non-SSDs, as the Kerberos authentication path has a blocking write to update account statistics), but you also get to regenerate the database, giving you the advantage of any new indexes since last upgrade.

  • How to Change File Extensions on Linux

    File extensions help both operating systems and users distinguish between different file formats and understand the contents stored inside them. When you see a file with the ".txt" extension, you instantly know it contains text data. Similarly, ".exe" file is a Windows executable and ".sh" files are Linux shell scripts. But what if you want to change these extensions for some reason? Perhaps you need to rename a text file to a Bash script. Simply writing the code in a text file won't do the job. On Linux, changing file extensions is much easier than you might think.

  • How to Install and Set up PostgreSQL Database on Ubuntu 22.04 LTS (Jammy Jellyfish) – LinuxWizardry

    PostgreSQL is a free and open-source relational database management system that allows both SQL and JSON querying. With over 30 years of active development, it has gained a solid reputation for its reliability, data integrity, extensibility, ACID compliance, and robust features. It allows you to create your own data types, define custom functions, and write different programming language codes without recompiling your database. It is compatible with all major operating systems including Windows, Linux/UNIX, Mac OS, IRIX, Solaris, etc. This tutorial will teach you how to install and set up PostgreSQL on the Ubuntu system.
