By next year, we'll be talking to databases in natural language
According to Gartner, natural language queries will replace SQL as early as 2026.
While Gartner's prediction may be optimistic, the shift toward natural language interfaces for databases is inevitable. The timeline may vary, but the transition itself is a certainty: https://u.habr.com/vOeSI

What is DPI Engine?
For people familiar with the term DPI (Deep Packet Inspection), it often carries an unpleasant association: blocking, regulators, censorship, tightening controls. In reality, DPI is simply the name of a technology whose essence lies in the deep analysis of network traffic. Deep traffic analysis involves identifying protocols, extracting the most significant fields and metadata, classifying internet services, and analyzing the nature of network flows. Let's find out how such solutions work: https://u.habr.com/iFaGK

How to catch and optimize problematic queries in PostgreSQL
If you work with PostgreSQL, you've likely run into performance issues at some point — especially as your database grows. Things may have been running smoothly at first, but as your client database expanded, queries started slowing down. Sound familiar? Here's a guide to help you identify and fix problematic queries, so you can get your PostgreSQL database running at peak performance again: https://u.habr.com/bwHMT

What's New in the Angie 1.9 Web Server (an nginx fork) and What to Expect from 1.10?
You may have already read in the news that on the eve of Cosmonautics Day, a new stable release of Angie 1.9.0 was released, an nginx fork that continues to be developed by the team of former nginx developers. Approximately every quarter, we try to release new stable versions and delight users with numerous improvements. This release is no exception, but it's one thing to read a dry changelog and quite another to get to know the functionality in more detail, to learn how and in which cases it can be applied: https://u.habr.com/RJiZ5

Captcha Solver Extension – Which to Choose: AI-Powered or Human-Powered? Difference Free and Paid CAPTCHA Extension
Imagine a developer automating routine tasks — for example, testing a web application or writing a data scraping script. Everything runs smoothly until a CAPTCHA appears on the path. In the browser, a familiar window pops up: "I am not a robot," or a grid of images where you need to find traffic lights or pedestrian crossings. The automatic script halts, tests fail, and an inexperienced developer might not even realize the problem for a long time — after all, they set everything up and started it, but didn’t account for the presence of CAPTCHAs (Completely Automated Public Turing test to tell Computers and Humans Apart), designed precisely to stop bots.

cgroups: how to eliminate the “noisy neighbor” effect in PostgreSQL
If you've ever run multiple instances of PostgreSQL or other software on a single machine (whether virtual or physical), you've probably encountered the "noisy neighbor" effect — when instances disrupted each other. So, how do you make them get along? We’ve got the answer!

Designing profitable software: architecture principles for business success
This article presents a business-driven approach to software architecture, focusing on maximizing profitability through technical decisions. It advocates for 1) distributed, stateless services with immutable models for scalability, 2) isolated third-party integrations without disrupting core logic, 3) simple, modular design.
