The construction of data centers is considered one of the most rapidly growing industries. Progress in this area is tremendous, but whether groundbreaking technological solutions will emerge in the near future remains a big question. Today, we will explore the main innovative trends in global data center construction to find an answer. The Shift Toward Hyperscale The development of information technology has necessitated building […]
Typically, monitoring and analyzing the performance of Nginx involves commercial products or established open-source alternatives like Prometheus + Grafana. This is a good option for monitoring or real-time analytics, but it's not the most convenient for historical analysis. On any popular resource, the volume of data from Nginx logs grows rapidly, and for analyzing large datasets, it makes sense to use something more […]

Facebook’s development aims at a more rapid and selective termination of processes consuming excessive memory before the Linux kernel’s OOM handler is triggered. The oomd code is written in C++ and is licensed under GPLv2. Oomd is already in use in Facebook's infrastructure and has proven effective under industrial loads (specifically, the project has nearly eliminated the occurrence of […]
Google has suggested that browser developers implement a practice of blocking the download of dangerous file types when the referring page is opened over HTTPS, but the download is initiated without encryption over HTTP. The issue is that during the download, there is no security indication; the file simply downloads in the background. When such a download is initiated from a page opened over HTTP, […]

After two months of development, the release of the system manager systemd 242 has been presented. Notable new features include support for L2TP tunnels, the ability to control the behavior of systemd-logind during restarts via environment variables, support for extended boot partitions XBOOTLDR for mounting /boot, the capability to boot with the root partition in overlayfs, and a large number of new settings for various unit types. Key changes: In systemd-networkd […]
The developers of the Matrix decentralized messaging platform announced an emergency shutdown of the Matrix.org and Riot.im (the main Matrix client) servers due to a hack of the project's infrastructure. The first shutdown occurred last night, after which the servers were restored, and the applications were recompiled from the reference source code. But just a few minutes ago, the servers were compromised for the second time. The attackers posted on the main […]
