It seems I have given dozens of presentations for colleagues, clients, and public speaking throughout my IT career. For many years, PowerPoint has been my natural and reliable choice for creating slides. However, this year, the situation changed dramatically. From February to May, I had the opportunity to speak at five conferences, and I needed to prepare slides for my presentations […]
Steve Langasek from Canonical announced the intention to provide users of future Ubuntu releases with the ability to use libraries for the 32-bit x86 architecture by borrowing these libraries from Ubuntu 18.04. It is noted that support for i386 libraries will continue but will be frozen at the state of Ubuntu 18.04. Thus, Ubuntu 19.10 users will be able to install the libraries necessary to run 32-bit […]
The final, most tedious reference article. Reading it for general knowledge may not make much sense, but when the time comes, it will be very helpful. Content of the series of articles Part 1: General architecture of the KTV network Part 2: Composition and form of the signal Part 3: Analog component of the signal Part 4: Digital component of the signal Part 5: Coaxial distribution network Part 6: RF signal amplifiers […]
Hello again! Today I would like to write a mini post and answer the question — 'Why remove wisdom teeth if they don't cause any discomfort?' and comment on the claim — 'My relatives and friends, dad/mom/grandpa/grandma/neighbors/pet had a tooth removed and everything went wrong. Absolutely everyone had complications and now no one wants to remove theirs.' First, I would like to say that complications […]
After six months of development, the release of the console file manager Midnight Commander 4.8.23 has been published, available in source code under the GPLv3+ license. Key changes include: Significant acceleration in the deletion of large directories (previously, recursive deletion of directories was significantly slower than 'rm -rf' as each file was iterated and deleted individually); The dialog layout shown when attempting to overwrite an existing file has been redesigned. The button […]
Hello! My name is Vadim Madison, and I lead the development of Avito's System Platform. We've discussed several times how our company is transitioning from a monolithic architecture to a microservices one. It's time to share how we transformed our infrastructure to maximize the benefits of microservices and ensure we don't get lost in them. How PaaS helps us here, as we […]
DDoS attacks remain one of the most discussed topics in the field of information security. However, not everyone realizes that bot traffic, which is the tool for such attacks, poses numerous other dangers for online businesses. Malicious actors can use bots not only to take a website down but also to steal data, distort business metrics, increase advertising costs, and damage reputation […]
Mastodon is a "decentralized Twitter." Microblogs scattered across numerous independent servers, interconnected into a single network. The closest analogy is regular email.

Added short_description and approval_required to the GET method […]
After more than two years of development, the GNU project has released GNU APL 1.8, an interpreter for one of the oldest programming languages — APL, fully compliant with the ISO 13751 («Programming Language APL, Extended») standard. The APL language is optimized for working with arrays of arbitrary nesting and supports complex numbers, making it popular for scientific calculations and data processing. […]
The TinyWare project has prepared builds based on the 32-bit version of Slackware-Current, offered with 32- and 64-bit versions of the Linux kernel 4.19. The size of the ISO image is 800 MB. Key changes compared to the original Slackware include: Installation on four partitions: «/», «/boot», «/var», and «/home». The «/» and «/boot» partitions are mounted in read-only mode, while «/home» and «/var» are in […]
Note: In the Kubernetes community, a trend known as GitOps is gaining explicit popularity, as we personally confirmed by attending KubeCon Europe 2019. This term was relatively recently coined by Weaveworks CEO Alexis Richardson and refers to the use of familiar tools for developers (primarily Git, hence the name) to address operational tasks. In […]
When setting up and configuring a Git server, the question arises about organizing access for multiple users to several projects. I conducted research on this issue and found a solution that meets all my requirements: simple, secure, and reliable. My requirements are as follows: each user connects with their own account, multiple users can work on one project, and the same user can work on several […]
