The C++ file templating engine Jinja2Cpp has been released. This file generator based on templates is analogous to the well-known Python jinja — http://jinja.pocoo.org/ The specification was taken from http://jinja.pocoo.org/docs/2.10/templates/ Articles by the author discussing some aspects and shedding light on obscure points can be found at https://habr.com/ru/post/416581/ and https://habr.com/ru/post/419011/.

French mathematician Fabrice Bellard, better known for his work on ffmpeg, qemu, tcc, and calculating pi, has released QuickJS — a compact implementation of JavaScript as a C library. It nearly fully supports the ES2019 specification, including mathematical extensions. It passes all tests in the ECMAScript Test Suite. There are no dependencies on other libraries. Its small size is statically […]
And there you are, standing in the middle of a rally, your heart and breath trying to escape your chest, your throat is dry, and a strange ringing fills your ears. You don't understand why all these people cannot grasp such simple rational arguments, which fit so smoothly into your worldview. Your inner voice screams: — "And why are such obvious […]
The term "virtual PBX," or "virtual phone system," means that the provider takes care of hosting the PBX itself and applying all the technologies necessary to provide communication services to companies. Calls, alerts, and other functions are processed on the PBX server located at the provider's facility. For these services, the provider issues a monthly bill that usually includes some […]
Building a telecommunications infrastructure is a complex task when there are no conditions, experience, or specialists. However, in this case, ready-made solutions such as container data centers can be used. In this post, we discuss how the data center of Campana in Myanmar was created, which today stands as one of the main switching hubs in the region and provides connectivity for underwater […]
In light of the impending barrier in chip production, which is the inability to further reduce the scale of manufacturing processes, multi-chip packaging of chips is coming to the forefront. The performance of future processors will be measured by the complexity, or rather the integration, of solutions. The more functions are assigned to a small processor chip, the more powerful and efficient the entire platform will be. At the same time, the processor itself will represent […]
The release of the Clonezilla Live 2.6.2 Linux distribution has taken place, designed for quick disk cloning (only used blocks are copied). The tasks performed by the distribution are similar to those of the proprietary product Norton Ghost. The size of the distribution's ISO image is 272 MB (i686, amd64). The distribution is based on Debian GNU/Linux and uses code from projects like DRBL, Partition Image, ntfsclone, partclone, and udpcast. Booting from […]
French mathematician Fabrice Bellard, who founded the QEMU and FFmpeg projects, created the fastest formula for calculating Pi, and developed the BPG image format, has published the first release of the new JavaScript engine QuickJS. The engine is compact and designed for embedding in other systems. The project code is written in C and is distributed under the MIT license. […]
A loud brand or a high-ranking speaker's name helps fill conference halls. People flock to the "stars" to stay trendy and learn about their mistakes and victories. However, at the end of the presentations, participants do not give such speakers very high ratings. In the studio for creating presentations and infographics VisualMethod, entrepreneurs and corporate employees found out that more […]
When I first began my acquaintance with Habr, my senior colleagues strictly advised me to watch out for double spaces and errors in texts. At first, I didn’t pay much attention to this, but after accumulating a lot of negatives in my karma, my attitude towards this requirement changed abruptly. Just recently, my good friend from St. Petersburg, who is not exactly a geek, Yana […]
Today, the need arose to monitor changes in specific files on the server. There are many different ways to do this, such as osquery from Facebook, but since I recently started using Open Distro for Elasticsearch, I decided to monitor files with Elastic, using one of its beats. I won't go into the details of installing the Elastic stack and Auditbeat; it’s all in the manuals. The only thing is, after installation, edit the auditbeat.yml file to […]
In the picture, the Linux kernel sends you greetings via GPIO. In this part of the story about porting the RISC-V RocketChip to a Chinese board with Cyclone IV, we will manage to run Linux and learn how to configure the memory controller IP Core ourselves and slightly edit the device tree source description. This article is a continuation of the third part, but unlike the previously sprawling one, it […]
