In grep 3.2, searches became successful if the processed file was mentioned in the list, but this has now reverted to the behavior where […]

Surely, everyone involved in the implementation of IPv6 or at least interested in this set of protocols knows about Google's IPv6 traffic graph. Similar data is collected by Facebook and APNIC, but for some reason, Google's data is the standard benchmark (although, for instance, there's no visibility into China). The graph is subject to noticeable fluctuations — traffic is higher on weekends, and noticeably […]
After four months of development, OpenSSH 8.4, an open implementation of client and server for working with SSH 2.0 and SFTP protocols, has been released.

The LibreOffice community has celebrated ten years since the project's establishment. Ten years ago, leading developers of OpenOffice.org formed a new non-profit organization, The Document Foundation, to continue the development of the office suite as a project independent of Oracle, not requiring developers to transfer ownership rights to the code, and making decisions based on meritocratic principles. The project was created a year […]
