As part of the Parallel GCC research project, work has begun on adding the capability to GCC that allows the compilation process to be divided into multiple concurrently executing threads. Currently, to increase build speed on multi-core systems, the make utility launches separate compiler processes, each of which compiles an individual source file. The new project experiments with providing […]
Have you ever wondered how many hours, months, and even lives have been wasted on solving the "wrong" problems? Once, some people started complaining about having to wait unbearably long for the elevator. Other people were concerned about these complaints and spent a lot of time, effort, and money trying to improve elevator operation and reduce wait times. But […]
Varlink is a core interface and protocol that is easy to read by both humans and machines. The Varlink interface combines traditional UNIX command-line parameters, text formats for STDIN/OUT/ERROR, man pages, service metadata, and is equivalent to file descriptor FD3. Varlink is accessible from any programming environment. The Varlink interface defines the methods that will be implemented and how. Each […]
Korean developer Park Ju Hyung, specializing in porting Android firmware for various devices, has introduced a new version of the exFAT file system driver — exfat-linux, which is a fork of the "sdFAT" driver developed by Samsung. Currently, the exFAT driver from Samsung has already been added to the Linux kernel's staging branch, but it is based on the old driver codebase (1.2.9). […]
In 2017, Sony released a very unusual, interesting, high-end, and insanely expensive camera, the RX0. It drew attention due to its incredible feature set in a compact size, while technically echoing the popular compact from the renowned Sony RX100 series. Externally, the RX0 resembled a typical action camera: it was water-resistant, drop-resistant, and […]
As a brief addition to the article Attempt to Create an ASH Analog for PostgreSQL. Task: It is necessary to link the history of pg_stat_statements and pg_stat_activity. As a result, using the execution plan history from the service table log_query, you can obtain a wealth of useful information for resolving performance incidents and optimizing queries. Warning: Due to ongoing testing and development, the article is not […]

Reddit user u/DavidAGra (David Jorge Aguirre Gracio) has introduced the first version of his own rocket flight simulator – 'F9sim' 1.0. Currently, this is a free simulator written in Delphi using OpenGL technologies, but the project author is considering opening the source code and rewriting the project's code in C++/Qt5. The original goal of the project is to create a realistic 3D simulation of the flight of the first stage of a launch vehicle […]

Following Mozilla, Google announced its intention to conduct an experiment to test the implementation of DNS over HTTPS (DoH) developed for the Chrome browser. In the upcoming Chrome 78 release, scheduled for October 22, some user categories will be switched to using DoH by default. Only users with certain system settings will participate in the DoH activation experiment […]
More and more companies are currently transitioning their infrastructure from physical servers and their own virtual machines to the cloud. This decision is easy to explain: there is no need to worry about hardware, clusters can be easily configured in many different ways... and most importantly, existing technologies (like Kubernetes) allow for straightforward scaling of computing power based on load. The financial aspect is always important. The tool […]
