Hello everyone. Below is the transcript of the report from Big Monitoring Meetup 4. Prometheus is a monitoring system for various systems and services, allowing system administrators to collect information about current system parameters and set up alerts to receive notifications about deviations in system performance. The report will compare Thanos and VictoriaMetrics — projects for long-term storage of metrics […]
The Linux kernel source code contains about 4,000 comments describing unfinished tasks, plans, and postponed future work, identified by the presence of the phrase 'TODO'. Most of the 'TODO' comments are found in driver code (2,380). There are 23 in the cryptographic subsystem, 43 in architecture-specific x86 code, 73 in ARM code, and in […]
After six months of development, the release of Firejail 0.9.62 is now available, which develops a system for isolating the execution of graphical, console, and server applications. Using Firejail minimizes the risk of compromising the main system when running untrusted or potentially vulnerable programs. The program is written in C, distributed under the GPLv2 license, and can run on any Linux distribution […]
In 2014, a rural school on the outskirts of Campo Maior in Brazil was connected to the internet. An ordinary event, if not for one 'but.' The connection was made via a stratospheric air balloon. This event marked the first success of the ambitious Project Loon, a subsidiary of Alphabet. Five years later, governments of countries affected by severe hurricanes and earthquakes are turning to […]
When developing plugins for CAD applications (in my case, this includes AutoCAD, Revit, and Renga), one issue inevitably arises over time – new versions of the software are released, their APIs change, and new versions of the plugins need to be created. If you only have one plugin or you are still a novice self-taught developer, you can simply make a copy of the project, modify it […]
It so happened that at the time the task was set, I did not have enough experience to develop and launch this solution on my own. So, I started googling. I don’t know what the catch is, but time and again, I find that even if I follow everything step-by-step as in the tutorial, preparing the same environment as […]
Indie developers often find themselves juggling multiple roles: game designer, programmer, composer, artist. And when it comes to visuals, many opt for pixel art — which seems simple at first glance. However, creating beautiful pixel art requires a lot of experience and specific skills. I found a tutorial for those just starting to grasp the basics of this style: it includes descriptions of special software and drawing techniques […]
I write a lot of texts, mostly nonsense, but usually even critics say that my writing is easy to read. If you want to make your texts (letters, for example) easier to read, hurry up here. I didn’t make this up; it's all from the book 'The Living and the Dead Word' by Nora Gal, a Soviet translator, editor, and critic. There are two rules: use verbs and avoid bureaucratic language. Verbs are […]
Daniel Robbins announced that after March 1, 2020, he will cease support and maintenance for release 1.3. Surprisingly, the reason for this is that the current release 1.4 has proven to be better and more stable than 1.3-LTS. Therefore, Daniel recommends those using version 1.3 to plan an upgrade to 1.4. In addition, a second maintenance release is expected in January for […]
Apparently, it's my karma: implementing standard tasks in various non-trivial ways. If anyone has a different perspective on the issue, please feel free to join the discussion to explore the matter. One fine morning, an interesting task arose to grant user groups permissions on various shares containing subfolders of projects with document folders. Everything was fine, and a script was written to assign permissions to the folders. […]
Translation of an article from engineer George Hilliard's blog Clickable I am an embedded systems engineer. In my spare time, I often look for things that can be used in designing future systems or something from my range of interests. One such area is cheap computers capable of supporting Linux, and the cheaper, the better. That’s why I delved deep into a rabbit hole […]
Hello! We teach people how to work with big data. It's hard to imagine an educational program on big data without its own cluster where all participants work together. For this reason, it is always included in our program 🙂 We handle its setup, tuning, and administration, while the participants run MapReduce jobs and use Spark there. In this post, we […]
