In preparation for the launch of the 'Network Engineer' course, we have prepared a translation of some interesting material. There's one remarkable thing about DMVPN that I encountered some time ago: DMVPN Per-Tunnel QoS. Obviously, I’m not the only one (as a lab rat) who thinks this is cool. Every time I show this to people, I see their eyes light up — a consequence […]
Testing of the pre-release version of the Xfce 4.16pre1 user environment has begun. The release is expected in October or November. The most notable change in the new branch is the transition of the interface to the GtkHeaderBar widget and the application of client-side decoration (CSD), which allowed for the placement of menus, buttons, and other interface elements in the window header. Among other changes, optional support has also been discontinued […]
The release of the Thunderbird 78.2.1 email client is now available, which has enabled built-in OpenPGP support by default for all users, used for end-to-end encryption of correspondence and signing emails with a digital signature. This release also disables the use of MD5, SM2, and SM3 algorithms in the OpenPGP implementation. The main difference between the built-in OpenPGP support and the previously offered Enigmail add-on is the use of the RNP library […]
Hello, Habr. Right now, OTUS is accepting applications for a new cohort of the 'Software Architect' course. In anticipation of the course launch, I want to share with you my original article. Introduction Choosing an architectural style is one of the fundamental technical decisions when building an information system. In this series of articles, I will explore the most popular architectural styles for application development and answer […]
We all love stories. We enjoy sitting by the campfire, recounting our past victories, battles, or just sharing our work experiences. Today is just such a day. And even if you’re not by the campfire, we have a story for you. A story about how we started working with the storage on Tarantool. Once upon a time in […]
Google has sent warnings to the developers of Android applications Husky, Fedilab, and Subway Tooter, which allow communication in decentralized social networks of the Fediverse, about the need to rectify violations of the Play Store catalog rules. They have been given 7 days to address the concerns, after which non-compliant applications will be removed from the Google Play catalog. The reason for the intended block mentions the possibility of using the applications to access […]
The Finnish company TietoEVRY has released a TTF font called "The Polite Type," which turns offensive English expressions, as deemed by the authors, into ligatures, replacing them with neutral expressions or blurred spots. Naturally, if you add the character 200C or 200B (zero width non-joiner or zero width space) and even an extra space or change the case, the censorship doesn’t activate. The font is declared "open-source," […]
TL;DR: I am writing a kernel module that will read commands from the ICMP payload and execute them on the server even if your SSH has crashed. For those who are eager, the entire code is on GitHub. Caution! Experienced C programmers may burst into bloody tears! I might be wrong even in terminology, but any criticism is welcome. This post is aimed at those […]

Part 1 — Direct Security Measures,” we discussed the security issues of WiFi networks and direct methods to protect against unauthorized access. There were […]
Hello, Habr! At the end of summer, we want to remind you that we are continuing our exploration of Kubernetes and decided to publish an article from Stackoverflow, demonstrating the state of affairs in this project as of early June. Happy reading! At the time of writing this article, Kubernetes is about six years old, and in the last two years, its popularity has grown so much that it consistently ranks in […]
