The code for VictoriaMetrics, a time series database compatible with Prometheus, is open source.

Posted on

The source texts of VictoriaMetrics have been opened — a fast and scalable DBMS for storing and processing data in the form of time series (a record forms time and a set of corresponding values for that time, for example, obtained through periodic sensor state polling or metric collection). The project competes with solutions such as InfluxDB, TimescaleDB, Thanos, Cortex, and Uber M3. The code is written in Go […]

An error in OpenSSL disrupted the operation of some openSUSE Tumbleweed applications after an update.

Posted on

The OpenSSL upgrade to version 1.1.1b in the openSUSE Tumbleweed repository led to functionality issues for some applications related to libopenssl that utilize Russian or Ukrainian locales. The problem arose after a change was made to the error message buffer handler (SYS_str_reasons) in OpenSSL. The buffer was set at 4 kilobytes, which turned out to be insufficient for some Unicode locales. The output of strerror_r, used for […]

How I wrote my monitoring

Posted on

I decided to share my story. Maybe this budget solution to a well-known problem will help someone. When I was young and full of energy and didn’t know where to channel it, I decided to do a little freelancing. I quickly managed to build my rating and found a couple of regular clients who asked me to maintain their servers on an ongoing basis. The first thing I thought of […]

Intel is working on optical chips for more efficient AI

Posted on

Photonics integrated circuits or optical chips potentially offer numerous advantages over their electronic counterparts, such as reduced power consumption and lower latency in computations. This is why many researchers believe they could be extremely effective in machine learning tasks and artificial intelligence (AI) development. Intel also sees significant potential for the application of silicon photonics in […]

В Firefox 69 по умолчанию будет прекращена обработка userContent.css и userChrome.css

Posted on

Mozilla developers have decided to disable the handling of userContent.css and userChrome.css files by default, which allow users to override the styling of websites or the Firefox interface. The reason for this default disabling is to reduce the browser's startup time. Modifying behavior through userContent.css and userChrome.css is extremely rare among users, and loading these CSS files consumes additional resources (optimization eliminates unnecessary access to […]

The test builds of Microsoft Edge have introduced a dark theme and a built-in translator

Microsoft continues to release fresh updates for Edge on the Dev and Canary channels. The latest patch includes minor changes, including a fix for an issue that could lead to high CPU usage during browser idle time, along with a few other improvements. The most significant enhancement in Canary 76.0.168.0 and Dev Build 76.0.167.0 is the built-in translator, which will allow users to read text from any website […]

In the Wayland session, GNOME 3.34 will ensure the launch of XWayland as needed.

Posted on

Changes have been incorporated into the code of the window manager Mutter, developed as part of the GNOME 3.34 development cycle, allowing for the automation of XWayland startup when attempting to run an application based on the X11 protocol in a graphical environment based on the Wayland protocol. The difference from the behavior of GNOME 3.32 and earlier releases is that, previously, the XWayland component was constantly running and required […]

Data recovery from XtraDB tables without a structure file, using a byte-by-byte analysis of the ibd file.

Posted on

Background It so happened that the server was attacked by ransomware, which, by a 'happy coincidence,' partially left .ibd files (raw data files of InnoDB tables) untouched, while completely encrypting .fpm files (structure files). The .idb files could be divided into: those recoverable through standard means and guides. For such cases, there is a great article; partially encrypted […]

On Axes and Cabbage

Posted on

Reflections on where the desire to pass the AWS Solutions Architect Associate certification comes from. Motivation one: “Axes”. One of the most useful principles for any professional is 'Know your tools' (or in one of the variations 'Sharpen the saw'). We’ve been in the cloud for a long time, but until now, they were just monolithic applications with databases deployed on EC2 instances — […]
