The Status of Universal Package Systems

Filed under
GNU
Linux

Billed as the future of package management, universal package systems like Snappy and Flatpak have failed to live up to their promise.

Remember universal package systems? Although AppImage, the earliest universal package system, was first released in 2004, the concept did not capture much attention until a decade later, when Canonical released Snappy and Red Hat released Flatpak. Each was presented as the next generation of package managers, usable by any distribution, and as a means to reduce the number of rival technologies. Yet in 2020, both Snappy and Flatpak have receded into the background, and the deb and RPM package management systems continue to dominate Linux, leaving the question of why Snappy and Flatpak did not fulfill their promises.

Two quick searches on DistroWatch reveal that, out of the 273 active distros listed, 39 support Flatpak, and 35 support Snap packages. At first, those may sound like respectable numbers, until you realize that a much more arcane deviation from the norm, like distros that do not ship systemd, can boast 99 distros. Moreover, those figures consist mainly of major distros that support Flatpak and Snap -- often both -- but still depend primarily on traditional package managers.

Benchmarking Firefox 83 Nightly With "Warp" Against Google Chrome On Linux

Following last week's news of Firefox Nightly flipping on their new JIT "Warp" update I was eager to run fresh benchmarks of the current Firefox releases compared to Google Chrome under Ubuntu Linux. Warp was enabled last week for Firefox 83 nightly builds with this "Warp" just-in-time JavaScript compiler update having various improvements in an effort to provide greater responsiveness and faster page load speeds. Numbers cited by Mozilla engineers on their JavaScript/SpiderMonkey team were frequently in the 5~15% range. Even instances like Google Docs load times on Windows was around 20% faster with Warp. This round of benchmarking was done with Firefox 81, Firefox 82 Beta 3, and Firefox 83 Alpha 1 nightly as of last week after Warp landed. A secondary run of Firefox 83 nightly was also done with WebRender force enabled on Linux. Plus Google Chrome 85 was also tested as the latest stable release. Read more

Linux-driven COM duo tap i.MX8M Plus

TechNexion’s rugged “EDM-G-IMX8M-PLUS” and “AXON-E-IMX8M-PLUS” modules run Linux on NXP’s 2.3 TOPS i.MX8M Plus with up to 8GB LPDDR4, 16GB eMMC, WiFi/BT, and starter kits. There are also new i.MX8M Mini and Nano EDM modules. TechNexion has posted product pages for two compute modules that feature NXP’s i.MX8M Plus. The EDM-G-IMX8M-PLUS is essentially the same as the wireless enabled Wandboard IMX8M-Plus-4G module option on the sandwich-style Wandboard IMX8M-Plus SBC announced in August. However, it offers up to 8GB LPDDR4 instead of 4GB. The AXON-E-IMX8M-PLUS provides essentially the same capabilities but in TechNexion’s more rugged, 58 x 37mm AXON form-factor, which was used on the i.MX8M Mini-based AXON-IMX8M-Mini module.
