System Architecture

For decades, we have been using software to chop up servers with virtualization hypervisors to run many small workloads on a relatively big piece of iron.

I use PostgreSql a lot in my working time. So recently, I spent some time refreshing and deepening my knowledge of PostgreSQL to improve my skills and experience in using it (writing and optimizing queries, creating new objects, etc.). And I found many awesome features and syntax sugar constructions that can tremendously ease your daily routine and eliminate problems that may appear while resolving sophisticated tasks. In this article, I will try to review 6 PostgreSql traits that seem to me the most important and easy-usable in a clear and brief way.

The idea of being able to write kernel code in the Rust language has a certain appeal, but it is hard to judge how well that would actually work in the absence of examples to look at. Those examples, especially for modules beyond the "hello world" level of complexity, have been somewhat scarce, but that is beginning to change. At the 2022 Kangrejos gathering in Oviedo, Spain, two developers presented the modules they have developed and some lessons that have been learned from this exercise.

What does a malicious package actually look like in practice? We'll walk through some hypothetical exercises to see how malware generally works, and what sort of functions we might expect, from relatively simple and temporary, to complex.

In today’s wireless and 5G era, companies and individuals encounter a rising number of security threats on their IT assets. Wireless RF signals can be intercepted by anyone with low-cost radio equipment and decoded using open-source software, thus it’s imperative to assess connected designs for security vulnerabilities. This includes conducting penetration tests, jamming, replay attacks, and other methods to assess vulnerabilities in internet-of-things (IoT) RF protocols like Bluetooth, ZigBee, 6LoWPAN, Z-Wave, etc.
