Programmer's move to Estonia: work, money, and cost of living

There are quite a few popular articles on Habr about relocating to different countries. I have gathered information about moving to the capital of Estonia, Tallinn. Today we will discuss how easy it is for a developer to find job openings with relocation options, how much one can earn, and what to generally expect from life in Northern Europe. Tallinn: a developed startup ecosystem. Despite the fact that the population of Estonia as a whole […]

Voltage control relay for the residential sector

It is now a fairly common practice to install voltage control relays in residential sectors to protect electrical equipment from neutral disconnection, as well as from overvoltage and undervoltage issues. On Instagram and YouTube, many of my colleagues can be seen facing problems in this area after installing voltage control relays from Meandr and several other manufacturers, which often fail […]

The DDR4-6016 mode has conquered the system based on the Intel Core i9-9900K processor

In the field of extreme memory overclocking, the first half of the year has been dominated by Intel's Coffee Lake Refresh processors, as they quickly advanced the limits of memory operation beyond DDR4-5500, although each subsequent step was achieved with increasing difficulty. The AMD platform managed to regain some ground after the release of the Ryzen 3000 processors, but the current memory overclocking record for systems based on […]

DPI (SSL inspection) contradicts the essence of cryptography, yet companies are implementing it

Chain of trust. CC BY-SA 4.0 Yanpas SSL traffic inspection (SSL/TLS decryption, SSL analysis, or DPI) is becoming an increasingly hot topic of discussion in the corporate sector. The idea of decrypting traffic seemingly contradicts the very concept of cryptography. However, the fact is that more and more companies are using DPI technologies, explaining it by the need to check content for malware, data leaks, and other […]

QMapShack 1.13.2

A new version of QMapShack has been released — a program for working with various online mapping services (WMS), GPS tracks (GPX/KML), and raster and vector map files. The program is a further development of the QLandkarte GT project and is used for planning and analyzing travel and hiking routes. Prepared routes can be exported to different formats and used on various devices and navigation […]

Release of the QMapShack 1.13.2 program for tourists

The release of the QMapShack 1.13.2 program for tourists is now available, which can be used in the planning stages of hikes for route plotting, as well as for saving information about traveled routes, keeping a travel diary, or preparing travel reports. QMapShack is a reworked and conceptually different branch from the QLandkarte GT program (developed by the same author), ported to Qt5. The code is distributed under the […]

Release of the PulseAudio sound server 13.0

The release of the sound server PulseAudio 13.0 has been announced, which acts as an intermediary between applications and various low-level audio subsystems, abstracting the interaction with hardware. PulseAudio allows for volume and sound mixing management at the application level, organizes input, mixing, and output of sound when multiple input and output channels or sound cards are present, and allows for on-the-fly changes in audio format […]

Release of Wine 4.16 and the Windows gaming launcher package Proton 4.11-4

Notable changes include: increased stability of mouse capture functions in games; improved cross-compilation support in WineGCC; enhanced compatibility with Windows debuggers; code related to management has been moved from kernel32 to kernelbase […]

How I Became a Programmer at 35

There are increasing examples of career changes, or rather specialization shifts, by middle-aged individuals. In school, we dream of a romantic or 'great' profession, we enter college based on trends or advice, but ultimately we end up working where we're hired. I'm not claiming that this applies to everyone, but it definitely does to most. And when life improves and […]

CacheBrowser Experiment: Bypassing the Chinese Firewall without a proxy using content caching

Image: Unsplash Today, a significant portion of all content on the Internet is distributed using CDN networks. Studies have also explored how various censors exert their influence over such networks. Researchers from the University of Massachusetts analyzed possible methods of blocking CDN content, using practices of the Chinese authorities as an example, and developed a tool to bypass such blocks. We have prepared an overview containing the main findings and […]

We are raising our DNS-over-HTTPS server

The author has repeatedly addressed various aspects of DNS operations in a number of articles published on the blog. Throughout, the main focus has always been on enhancing the security of this critical Internet service. Until recently, despite the clear vulnerabilities of DNS traffic, which largely remains unencrypted, malicious actions from […]
