Всех приветствую, читатели Хабра! В сегодняшней статье я поделюсь примерами поиска возможных уязвимостей (и соответственно эксплоитов под уязвимости), причем, постараюсь проводить поиск по программному обеспечению от корпорации Apple.Среди моих коллег, друзей, товарищей, знакомых, соседей и близких бытует мнение о том, что платформы macOS и iOS неуязвимы, несокрушимы. Это не совсем так. В начале моей сегодняшней статье я немного развею это утверждение, просто обнаружив в базах эксплоитов примеры возможных э Read more ›

DBAs often struggle to identify the most resource-hungry processes that degrade system performance. Back in 2017, DBA — and now Postgres Professional engineer — Andrey Zubkov faced the same challenge. This led him to develop pg_profile for PostgreSQL, which has since evolved into pgpro_pwr.In this article, we’ll dive into strategic database monitoring and show you how to pinpoint bottlenecks in your databases using our tools.

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 ›

Hi, my name is Ilia. I founded Perfect Wiki — a SaaS product for creating internal company knowledge bases that works directly within Microsoft Teams. We created a simple and convenient tool for storing, editing, and sharing knowledge within companies.

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...

Продолжаем обсуждать серверы в контуре высоконагруженных 1С-систем. В предыдущей статье я рассматривал типичные проблемы с серверами СУБД, а сегодня перейдем к серверам 1С. Причем не хочется, чтобы пост превратился в очередной универсальный перечень настроек сервера 1С на все случаи жизни. Поэтому будем смотреть на задачу через призму производительности системы. Главное, сначала увидеть картину целиком, понять причину и, исходя из этого, менять пусть те же самые настройки 1С. Цель статьи –... Read more ›

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. I will explain how such solutions... Read more ›
