Qt Company announced in its blog the availability of the first preview build of Qt 6.0. The company states that the first preview build contains binary files only for desktop platforms, and testing on mobile and embedded platforms will require using a source code build.

You can copy multiple ISO files and select the needed one from the boot menu. Both Legacy BIOS and UEFI modes are supported. […]
Introduction Previously, the topic of automating desktop GUI applications with Python was covered in great detail on Habr. I was very drawn to that article because it revealed elements similar to those involved in creating robots. As part of my professional activities, I work on automating business processes for a company (RPA is a field that lacked fully functional […]
The Python library pywinauto is an open-source project for automating desktop GUI applications on Windows. In the last two years, it has gained significant new features: Support for MS UI Automation technology.

The developers of the free antivirus package ClamAV have resolved the issue of providing a signature database based on the Safe Browsing collection distributed by Google, which contains information about phishing sites and those distributing malware. Previously, the Safe Browsing-based signature database was provided by ClamAV developers, but in November of last year, its updates were halted due to restrictions imposed by Google. In particular, […]

The package is distributed under LGPL and GPL licenses, and FFmpeg development is conducted in parallel with the MPlayer project. Notable changes added in FFmpeg 4.3 include: Support for the Vulkan graphics API; Based on […]
Once, a regular firewall and antivirus programs were sufficient to protect a local network, but against attacks from modern hackers and the surge of malware lately, this setup is no longer effective. The good old firewall only analyzes packet headers, allowing or blocking them based on a set of formal rules. It knows nothing about the content of the packets, and therefore cannot […]
Good day! Let's continue to explore this topic (the previous part can be found at the link). Today we will move on to the practical part. We'll start by setting up our own certificate authority based on the full-featured open-source cryptographic library openSSL. This algorithm was tested using Windows 7. After installing openSSL, we can perform various cryptographic operations (for example, key generation and […]

It has long been known that making backups in SQL dumps (using pg_dump or pg_dumpall) is not the best idea. For backing up PostgreSQL databases, it's better to use the pg_basebackup command, which creates a binary copy of the WAL logs. But when you start exploring the entire process of creating a backup and restoration, you'll realize that you need to create at least a couple of tricycles to manage all of this […]
