While information technology continues to evolve rapidly, virtualization remains a cornerstone of modern computing, enabling businesses tomaximise resource utilisation, enhance flexibility, and reduce the total cost of ownership (TCO). It is a key building block of thecloud computingparadigm, and millions...
There are no fewer than three RCU mechanisms in the Linux kernel; the diagram above shows the first one, which is by far the most commonly used. The rcu_dereference() and rcu_assign_pointer() primitives are used for all four mechanisms, but different defer and protect primitives are used ...
This way, the Linux kernel remains safe even when the root account is compromised. Linux kernel lockdown comes in two modes- Integrity and Confidentiality. Activating the integrity mode deactivates features that permit the root account (user) to modify the functioning kernel. On the other hand,...
Gentoo Linux is a powerful and extensibledistributionthat stuck to the original source-based package management. Further, its package manager, portage, is a powerful utility that allows you to fine-tune and tweak each distribution aspect. However, it is not a distribution that is easy to install...
What is the Linux High Availabi 简介: 高可用性群集的出现是为了使群集的整体服务尽可能可用,以便考虑计算硬件和软件的易错性。如果高可用性群集中的主节点发生了故障,那么这段时间内将由次节 点代替它。次节点通常是主节点的镜像,所以当它代替主节点时,它可以完全接管其身份,并且因此使系统环境对于用户是一致的。
Virtual log file growth In previous versions of SQL Server, if the next growth is more than 1/8 of the current log size, and the growth is less than 64 MB, four VLFs were created. In SQL Server 2022 (16.x), this behavior is slightly different. Only one VLF is created if the grow...
BusyBox is superb alternative to GNU Coreutils specially in cases where the small size of the operating system matters big. 🗒️ BusyBox gives you popular Linux commands like mv,mkdir, ls etc but it contains only the common used options of these commands. This minimalism is the USP of ...
Notice how the shell prompt changes to green-ish color? It's because it reads /etc/bash.bashrc file and Ubuntu has put additional parameters in this file. Colored prompt is one of them. To summarize: The profile files are for interactive login shells. The rc files are for interactive non...
In .NET 8, we're refining some of the fundamentals such as size. Publishing app with Native AOT creates a fully self-contained version of you app that doesn't need a runtime - everything is included in a single file. We worked on making this single file smaller. Linux builds are now...
In .NET 8 Preview 6, support for the SHA-3 hashing primitives is now available on platforms that offer SHA-3. This is currently Linux with OpenSSL 1.1.1 or later, and Windows 11 Build 25324 or later. APIs where SHA-2 is available now offer a SHA-3 compliment. This includes SHA3_256...
