Linux 6.2 exFAT update to improve performance when creating files and directories

The exFAT file system is about to get faster in Linux 6.2, at least when creating files and directories, with the performance boost especially noticeable on low-end processors. Microsoft released the exFAT specification and announced Linux support in August 2019, which was followed by a new exFAT implementation in Linux 5.7 (June 2020) from Samsung.  But people are still working on improving exFAT Linux support, and Yuezhang Mo, an engineer at Sony, committed a patchset for Linux 6.2 that reduces repeated traversal of directory entries to boost the performance of exFAT: After traversing all directory entries, hint the empty directory entry no matter whether or not there are enough empty directory entries. After this commit, hint the empty directory entries like this: 1. Hint the deleted directory entries if enough; 2. Hint the deleted and unused directory entries which at the end of the cluster chain no matter whether enough […]

LapPi 2.0 – A DIY laptop for Raspberry Pi 4 and other single board computers (Crowdfunding)

The LapPi 2.0 is a DIY laptop kit with an acrylic enclosure, a UPS HAT with a 18650 battery holder, and off-the-shelf parts including speakers, a touchscreen display, a Raspberry Pi camera, and a wireless keyboard that’s suitable for the Raspberry Pi 4 and pretty much any other small single board computer from Radxa, Orange Pi, Banana Pi, FriendlyElec, Hardkernel, and others. We’ve seen several Raspberry Pi laptops over the years with the CrowPi L and Pi-Top, and I have to say the LapPi 2.0 is not the most eye-pleasing or sophisticated design, but at least, it’s versatile and not limited to the Raspberry Pi family. LapPi 2.0 kit content and highlights: Display – 7-inch 5-point capacitive touchscreen IPS display with 1024×600 resolution support for audio output via 3.5mm audio jack and 4-pin header Camera – Official 8MP Raspberry Pi Noir camera with night vision support Audio – 2x 5W/8 […]

Raspberry Pi availability improves, “unlimited supplies” expected by H2 2023

The Raspberry Pi SBCs have been in short supply for a couple of years, especially for individual buyers since Raspberry Pi Trading prioritizes commercial customers, but Eben Upton has just announced some good news with over 100,000 boards comprised of a mix of Raspberry Pi Zero W, Pi 3A+, and Raspberry Pi 4 2GB and 4GB variants being made available for single-unit sales through approved resellers. Eben however notes there’s more to do, and recommends buying from an approved reseller to get the boards at the recommended retail price (RRP), checking rpilocator to check for availability, and potentially considering switching to the Raspberry Pi Pico or Pico W if the project allows it as there’s plenty of stock for the MCU boards. Industrial and enterprise customers who still have issues can get in touch with the company by email using business <at> raspberrypi.com. But based on some feedback I received, […]
