TVs With Linux and Raspberry Pi Latest

• From Plex to Jellyfin Media Server

  I migrated away from Plex just a week before its much over-publicized “security issues” last month. I just want to go on the record and say that my decision had nothing to do with this incident. The “security issue” boiled down to Plex not behaving ideally on mismanaged and insecure network configurations. In my opinion, Plex isn’t to blame for security errors in network configurations made by inexperienced network administrators.

• The first Rockchip RK3566 TV box is out with H96 Max running Android 11

  Rockchip RK3566 is a quad-core Cortex-A55 processor with plenty of peripherals designed for AIoT and NVR applications. While it still supports features like high-dynamic range or video post-processing, it’s not really optimized for TV boxes, but this has not stopped the maker of H96 Max “8K UltraHD” TV box to launch an RK3566 model with 4GB RAM and 8GB RAM now sold for respectively $59.99 and $76.99 on Banggood.

• Linux 5.13 To Support HDMI CEC With The Raspberry Pi 4

  While the 5.12 merge window hasn't even been closed for a full week yet, there is already the first DRM-Misc-Next pull request heading into DRM-Next with the first batch of feature material aiming for the Linux 5.13 kernel cycle. This initial batch of DRM-Misc-Next includes the removal of TTM memory management and Medfield support from the GMA500 "Poulsbo" driver that goes along with the rest of the Linux kernel dropping the Intel MID support for 5.12 and lingering remnants being removed with 5.13. There is also i.MX8MM support added to the MSXFB driver among many other random changes to these smaller drivers.

AMD Linux 5.12 and Linux 5.10.20

• VCN-Less Navi 12 SKU, RX 6000 Series BACO Runtime PM Are Extras For Linux 5.12 - Phoronix

  A set of "fixes" to the AMDGPU kernel driver were mailed out today that include a few notable changes for some post merge window alterations.

• Linux 5.10.20 Released - Fixes The Erroneous Record-Breaking AMD Clock Frequencies - Phoronix

  Recent kernel point releases have reported erroneous maximum frequencies on AMD Zen 2 / Zen 3 CPUs in the area of 6GHz+ while now with the latest stable releases that is being fixed. Linux 5.10.20 LTS is out this morning and it comes with an important fix particularly for AMD Zen 2 / Zen 3 users. The Linux 5.11 fix for that AMD performance regression stemming from the introduction of CPU frequency invariance ended up introducing a regression in the CPU frequency reporting.

Ubuntu: Unbreaking Unbootable Ubuntu, Snaps Shrunk and More

• Unbreaking Unbootable Ubuntu

  I run Ubuntu Hirsute - the development release which will become 21.04 - on a bunch of systems. It’s a trade-off though, getting the latest crack each and every day. Being at the bleeding edge of new packages landing means I can experience brand new shiny bugs on my systems. Bugs like 1915579 which rendered my system unbootable.

• Honey, I Shrunk the Snap! | Ubuntu

  The year is 1989. I bought a computer game called F-16: Combat Pilot, a flight simulator featuring free-flight, five types of single-player missions, a full campaign mode, serial-port multiplayer, and then some. Gloriously wrapped in four colors and magnetized on two single-density 5.25-inch floppy disks. Total size: 680 KB. Nowadays, it is not uncommon for individual applications to weigh dozens if not hundreds of megabytes. But it doesn’t have to be that way. In Linux, you can save some space by using libraries that are shared across multiple applications (hence their name, shared libraries). When it comes to self-contained application formats like snaps, the tables are turned once again, as snaps bundle all the necessary dependencies inside, and thus take more disk space. If you want to make your snapped applications as small and lean as possible, we have a few neat suggestions. [...] The final artifact of the snap build process is a compressed squashFS file, with the .snap suffix. Originally, snaps were compressed using the xz algorithm, for highest compatibility with the widest range of devices. More recently, in order to help speed us snap launch times, we also introduced the use of the lzo algorithm, which results in 2-3x application startup times improvements. The main reason for this is the lesser compression used in lzo compared to xz, meaning the system needs fewer CPU cycles, and thus less time, to uncompress the snap on the system. However, it also introduces size inflation. [...] Disk utilization matters less now than it did a decade or two ago, but you can still try to make your applications small and tidy. This also helps reduce bandwidth usage, improves portability, and if you’re using system backups, reduces the time needed to copy all the relevant data. With snaps, there are many ways you can trim down on the digital excess, including the use of extensions, sparing use of necessary runtime dependencies, and pruning the extras from the prime directory. Not only will your snaps be smaller in size, you will also ensure higher consistency, better system integration and improve the application startup time. All these are important, highly noticeable elements of the user experience. If you have any other suggestions or ideas on how to conserve space or optimize snap creation, please join our forum and share your thoughts.
