SQL is not C++ or JavaScript. Therefore, the evaluation of logical expressions occurs differently, and this is not the same: WHERE fncondX() AND fncondY() = fncondX() && fncondY(). In the process of optimizing the execution plan of the query, PostgreSQL can arbitrarily 'rearrange' equivalent conditions, not evaluate some of them for individual records, relating to […]

The main Linux distributions have formed a corrective update for the GRUB2 bootloader package, addressing issues that arose after the BootHole vulnerability was patched. After the installation of the first update, some users encountered the inability to boot their systems. Boot issues occurred on some systems with BIOS or UEFI in 'Legacy' mode and were caused by regression changes that, in certain situations, led to crashes in […]
A study conducted on the portal BSD-Hardware.info indicates that hardware support in FreeBSD is not as poor as commonly claimed. The evaluation took into account that not all hardware on the market is equally popular. There are widely used devices that need support, and there are rare devices whose owners can be counted on one hand. Accordingly, the weight of each individual device in the assessment was considered […]
One of the common types of attacks is the spawning of a malicious process within a tree of otherwise legitimate processes. Suspicion may arise from the path to the executable file: malware often uses AppData or Temp folders, which is uncharacteristic of legitimate programs. Fairness dictates noting that some automatic update utilities run in AppData, so merely checking the location […]

Christoph Hellwig, a well-known Linux kernel developer and former member of the governing technical committee of the Linux Foundation, who was a plaintiff in a GPL-related lawsuit against VMware, has proposed to tighten protections against the binding of proprietary drivers to Linux kernel components exported only for GPL-licensed modules. To circumvent the limitation on exporting GPL symbols, producers […]
The release of the open-source platform for deploying decentralized social networks—Mastodon 3.2—has been announced, allowing users to create services on their own infrastructure that are not controlled by individual providers. If a user cannot launch their own node, they can choose a trustworthy public service for connection. Mastodon falls into the category of federated networks, where a set of […] is used to form a unified structure of connections.
