What Is SSH and What Does It Stand For?
OpenSSH is a widely-used open-source implementation of SSH. The original free version of SSH was developed by Tatu Ylönen. Later versions of Ylönen's work were proprietary, meaning they cost money to license and use, and you couldn't make unauthorized changes to the protocol.
Thus, a team of developers forked the original free version of SSH and named it OpenSSH, which is now developed as part of OpenBSD (an open-source operating system). All major operating systems, such as Windows, macOS, and the numerous Linux distributions, support OpenSSH.

OpenSSL, LibreSSL, LibreTLS and all the terminological irony – Michał Górny
While we’re discussing the fate of LibreSSL, it’s worth noting how confusing the names of these packages became. I’d like to take this opportunity to provide a short note on what’s what.
First of all, SSL and its successor TLS are protocols used to implement network connection security. For historical reasons, many libraries carry ‘SSL’ in their name (OpenSSL, LibreSSL, PolarSSL) but nowadays they all support TLS.

Reproducible Builds (diffoscope): diffoscope 164 released
The diffoscope maintainers are pleased to announce the release of diffoscope version 164. This version includes the following changes:
[ Chris Lamb ] * Truncate jsondiff differences at 512 bytes lest they consume the entire page. * Wrap our external call to cmp(1) with a profile (to match the internal profiling). * Add a note regarding the specific ordering of the new all_tools_are_listed test. [ Dimitrios Apostolou ] * Performance improvements: - Improve speed of has_same_content by spawning cmp(1) less frequently. - Log whenever the external cmp(1) command is spawn.ed - Avoid invoking external diff for identical, short outputs. * Rework handling of temporary files: - Clean up temporary directories as we go along, instead of at the end. - Delete FIFO files when the FIFO feeder's context manager exits. [ Mattia Rizzolo ] * Fix a number of potential crashes in --list-debian-substvars, including explicitly listing lipo and otool as external tools. - Remove redundant code and let object destructors clean up after themselves. [ Conrad Ratschan ] * Add a comparator for Flattened Image Trees (FIT) files, a boot image format used by U-Boot.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
