[gentoo-dev] Reliability test for hard drives and SSD
Hi there! Good news for all interested in hardware compatibility and reliability. I've started a new project to estimate reliability of hard drives and SSD in real-life conditions based on the SMART data reports collected by Linux users in the Linux-Hardware.org database since 2014. The initial data (SMART reports), analysis methods and results are publicly shared in a new github repository: https://github.com/linuxhw/SMART. Everyone can contribute to the report by uploading probes of their computers by the hw-probe tool! The primary aim of the project is to find drives with longest "power on hours" and minimal number of errors. The following formula is used to measure reliability: Power_On_Hours / (1 + Number_Of_Errors), i.e. time to the first error/between errors. Please be careful when reading the results table. Pay attention not only to the rating, but also to the number of checked model samples. If rating is low, then look at the number of power-on days and number of errors occurred. New drive models will appear at the end of the rating table and will move to the top in the case of long error-free operation. Thanks to ROSA, Gentoo, openSUSE, Arch, Fedora, Ubuntu, Debian, Mint users and others who had made this work possible by contribution to the database!

Example for symbol tox_pass_key_derive: https://abi-laboratory.pro/index.php?view=navigator=tox_pass_key_derive Search for data types will be implemented a bit later. Currently you can search for functions, methods and global data only. Thank you.

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 symbol dwelf_strtab_add from libdw.so (elfutils): https://abi-laboratory.pro/index.php?view=navigator=dwelf_strtab_add%40%40ELFUTILS_0.167#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.

[gentoo-dev] ABI compliance checker
Colleagues, I'm software engineer from Institute for System Programing of Russian Academy of Sciences and we are developing a free lightweight tool for checking backward/forward binary compatibility of shared C/C++ libraries in OS Linux. It checks interface signatures and data type definitions in two library versions (headers and shared objects) and searches ABI changes that may lead to incompatibility. We have released 1.1 version of this tool and we'd like you to consider its usefulness for your project. The wiki-page with the latest release of binary compatibility checker is http://ispras.linux-foundation.org/index.php/ABI_compliance_checker Andrey Ponomarenko
