ABI Navigator — a project to search for binary symbols
Hello, I'd like to present a new project called "ABI Navigator" for searching binary symbols (functions, methods, global data, etc.) in open-source libraries: https://abi-laboratory.pro/index.php?view=navigator The project allows to find out in which versions of libraries some symbol is defined, added, removed or changed. The data is taken from the ABI Tracker project (238 libraries and 0.9 million symbols currently): https://abi-laboratory.pro/tracker/ Example for _ZN5Botan18LibraryInitializer10initializeERKSs from libbotan.so: https://abi-laboratory.pro/index.php?view=navigator&selected=_ZN5Botan18LibraryInitializer10initializeERKSs#result The project aims to help Linux developers and maintainers to resolve issues with missed symbols and navigate through the reports in the ABI Tracker. Have you ever encountered the "undefined reference" error or want to know whether the symbol is _stable_ enough to use in your code? Try to find it in the ABI Navigator! Enjoy! -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
The alternative implementation of Ubuntu user statistics
Hello, I've recently initiated a new statistical project based on anonymously collected outputs of hwinfo, smartmontools and dmidecode utilities called "Linux Hardware Trends". The report for Ubuntu is now here: https://github.com/linuxhw/Trends/tree/master/Dist/Ubuntu The report can be considered as an alternative to Ubuntu user statistics (https://ubuntu.com/desktop/statistics) and helps to answer questions like "How popular are 32-bit systems?", "How fast is SSD market share growing?", "Which hard drives are less reliable?", "How many computers use old CPU microcode?", "How good is device drivers support?", etc. Please let me know if you are interested in tracking any OS/hardware characteristics that are not currently included in the report. The data is collected by the Snap package here: https://snapcraft.io/hw-probe Thanks. -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss

The common use case for SMART stats is to estimate failure probability of your old drives by comparing them with other people drives of the same model in the list [1]. This is a proven approach used by companies like Google, Backblaze and Acronis. See also [2]. Thanks.

Disappeared "Launch" button in the Snap Store (Ubuntu Software)
The "Launch" button is not available for snaps in recent Ubuntu versions since at least 2019-09-13: https://bugs.launchpad.net/snap-store-desktop/+bug/1843898 Looks like a showstopper bug. People install apps, but can't launch them. Instead they should find installed apps somewhere in the system. Why doesn't anyone care? -- Ubuntu-devel-discuss mailing list Ubuntu-devel-discuss@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-devel-discuss
