The goal of the fork is to enable more active development of Kwin, increase the necessary functionality for Wayland, and optimize rendering. Classic Kwin suffers from […]
Have you ever experimented with code or system utilities in Linux in a way that protects the base system and avoids complete failure in case of errors in code that needs to run with root privileges? What about the need to test or launch a whole cluster of various microservices on a single machine? A hundred or even a thousand? […]
The translation of the article has been prepared in anticipation of the start of the course 'Pentest. Practical Penetration Testing.' Abstract Various types of security assessments, ranging from regular penetration testing and Red Team operations to hacking IoT/ICS devices and SCADA, involve working with binary network protocols, essentially intercepting and modifying network data between the client and the target. Network sniffing […]

The developers of the Zimbra collaboration and email suite, positioned as an alternative to MS Exchange, have changed their open-source publication policy. Starting with the release of Zimbra 9, the project will no longer publish binary builds of the Zimbra Open Source Edition and will limit itself to the release of the commercial version, Zimbra Network Edition. Moreover, the developers do not plan to release the source code of Zimbra 9 for the community […]
For Fedora 33, a change is planned that will transition the distribution to using systemd-resolved by default for DNS query resolution. Glibc will be switched to nss-resolve from the systemd project instead of the built-in NSS module nss-dns. Systemd-resolved performs functions such as maintaining settings in the resolv.conf file based on DHCP and static DNS configuration data for network interfaces, supports DNSSEC, and LLMNR (Link […]
Changes have been accepted into the codebase of 'ZFS on Linux', developed under the auspices of the OpenZFS project as a reference implementation of ZFS, adding support for the FreeBSD operating system. The code added to 'ZFS on Linux' has been tested in FreeBSD versions 11 and 12. Thus, FreeBSD developers no longer need to maintain their own synchronized branch of 'ZFS on Linux', and the development of all related components [...]
For obvious reasons, this year's traditional Red Hat Summit will take place online. Therefore, there is no need to buy plane tickets to San Francisco this time.

The event program includes both traditional presentations and demonstrations, as well as interactive sessions and project booths, [...]
Content Delivery Networks (CDNs) are used on websites and in applications mainly to speed up the loading of static elements. This is achieved by caching files on CDN servers located in different geographical regions. When a user requests data via a CDN, they receive it from the nearest server. The principle of operation and functionality are roughly the same across all content delivery networks. Upon receiving a request to load [...]
