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 […]
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 […]
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 […]
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 […]
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 […]
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 […]
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. […]
In the previous part, a more or less functioning memory controller was implemented, more specifically, a wrapper over the IP Core from Quartus, serving as an adapter to TileLink. Today in the section "Porting RocketChip to an obscure Chinese board with Cyclone," you will see a working console. The process has dragged on a bit: I thought I would quickly run Linux and move on, but […]
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 […]
Microsoft wants users to abandon passwords on Windows 10 PCs. Previously, the company had stopped forcing password changes for corporate PCs, and now they have released a test build of the "ten" where passwordless sign-in for Microsoft accounts can be enabled. As an alternative, Windows Hello facial recognition technology, fingerprint scanning, or PIN codes are offered. […]
SQLite 3.29.0 has been released, a lightweight DBMS designed as a dynamic library. The SQLite code is released into the public domain, meaning it can be used freely and without restrictions for any purpose. The financial support for SQLite developers is provided by a specially created consortium that includes companies like Adobe, Oracle, Mozilla, Bentley, and Bloomberg. Key changes: New options have been added to sqlite3_db_config() […]
The release of the AndroWish application ("Eppur si muove") has been prepared, allowing Tcl/Tk scripts to run on systems with the Android platform without modification or with minimal changes (for example, tkabber works). The project provides a native port of Tcl/Tk 8.6 for Android version 2.3.3+ for Arm and x86. It includes everything necessary for operation, including an X11 emulator, SDL 2.0, and FreeType for rendering […]
