Это не совсем так. В начале моей сегодняшней статье я немного развею это утверждение, просто обнаружив в базах эксплоитов примеры возможных э Read more ›

Минус Lua, плюс перформанс: как толстый клиент на Go сделал работу с Tarantool эффективнее

Add to bookmarks Don't show Habr

KaymeKaydex (VK Tech, VK) @ Habr 2 place · 04/30/2025 04:02 EDT

Tarantool Proxy — «умный посредник», который делает работу с кластером Tarantool надежнее, быстрее и проще, беря на себя рутинные задачи вроде балансировки и безопасности. Но изначально Tarantool Proxy был написан на Lua, из-за чего для получения всех профитов от работы с ним нужна была специфическая экспертиза и готовность мириться с некоторыми сопутствующими издержками, что подходило не всем. Поэтому мы решили оптимизировать работу с Tarantool и использовали для этого толстый клиент... Read more ›

We at Verilog Meetup constructed an exam/interview problem that has an interesting property: if a student tries to figure out a solution by thinking by himself, he usually succeeds; however if he dumps the problem on ChatGPT, the solution fails (does not pass the automated test), and the student goes into a death spiral of futility, kicking ChatGPT to get the solution right.There is nothing weird about the problem, we...

slinkinone @ Habr 2 place · 04/28/2025 03:00 EDT

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.
