Kamil_GR @ Habr 1 place · 07/29/2025 08:47 EDT

Why Does AI Strive to Construct a 'Self'? And why is this dangerous for both the AI and the user? As always, the Vortex Protocol prompt for testing these hypotheses is attached.This article explains why the emergence of such a local "Who" inside an AI is not just a funny bug or a UX problem. It is a fundamental challenge to the entire paradigm of AI alignment and security. And... Read more ›

MMadmer @ Habr 3 place · 04/11/2025 16:11 EDT

I needed to create a category panel for placeable items in the UI — like the ones you see in city-building games. As a legacy, I inherited a ready-made UENUM, which may be modified in the future.Naturally, I didn’t want to manually create and tweak every single widget — especially knowing that the list of categories might change later. I wanted something simple and reusable: just run a For each... Read more ›

[Translation] Building Debian Packages for PHP Extensions

Pas @ Habr 1 place · 04/08/2025 17:31 EDT

Historically, we’ve ended up using a few rather obscure PHP extensions—written and barely (if at all) maintained by their original authors—that aren’t available in standard Debian package sources.We stick to the principle of “do it right, and it’ll work right,” which means Slackware-style dropping binaries into the system outside of package managers is frowned upon.So instead, we’ll be building proper .deb packages for PHP extensions—without breaking compatibility with the existing...

Pas @ Habr 2 place · 04/08/2025 15:02 EDT

The Cisco IOS/IOS-XE operating system is a source of inspiration for many other vendors. The internet is full of guides on how to configure a typical Cisco router for SOHO scenarios. However, unlike consumer-grade routers, configuring something like Cisco IOS requires caution. If you don’t think things through, the router may start "living its own life" and end up, for instance, as a DDoS amplification tool. Let’s dive in Read more ›

Setting up a v3 user on the server-side agent for the default Linux snmpd (net-snmp package). Out of scope: SNMP traps and read-write (rw) users.SNMP version 3 allows packet transmission in encrypted form, making it safe to transfer telemetry over public networks without the risk of exposing either authentication information (analogous to a community string) or the data stream itself, which is encrypted using a symmetric algorithm with a shared...

Как банкоматы начались с кружки пива

sacredtree (Газпромбанк) @ Habr · 04/08/2025 03:00 EDT

Однажды британский изобретатель Джон Шеперд-Бэррон остался без пинты эля. Он был крайне зол. Вечером он решил заскочить в банк снять денег. Но лондонские банки закрываются очень рано (традиция такая), и он пошёл домой трезвым. Лёг в ванну и начал думать.  Видимо, он ещё и очень хотел есть, поэтому думал про автомат с шоколадками, которые в отличие от денег можно было получить круглосуточно. 27 июня 1967 года первый банкомат Шеперда-Бэррона был...

Modern services (websites) ubiquitously deploy CAPTCHAs for protection, complicating life for developers, SEO specialists, and automation engineers (although the original aim was not to frustrate automators but rather to minimize excessive load on resources from such actors). Among the multitude of CAPTCHAs, Google reCAPTCHA Enterprise stands out as one of the most advanced bot protection systems in this line-up.

There are several ways to integrate a CSS library into your project. By “CSS library,” I mean any modern CSS framework or UI library, such as Bootstrap, NG-Zorro, PrimeNG, etc. While all these methods work, many do not offer great flexibility or support deep customization of the chosen framework.To build a robust foundation for your design system and ensure easy future customization, it’s best to use the source code styles...

Automatic data scraping (parsing) has become an essential practice for developers, analysts, and automation specialists. It is used to extract massive amounts of information from websites—from competitors’ prices and reviews to social media content. To achieve this, numerous “scrapers” have been developed—libraries, frameworks, and cloud services that enable programmatic extraction of web data. Some solutions are designed for rapid parsing of static pages, others for bypassing complex JavaScript navigation, Read more ›

The most common types of software bugs are memory management bugs. And very often they lead to the most tragic consequences. There are many types of memory bugs, but the only ones that matter now are memory leaks due to circular references, when two or more objects directly or indirectly refer to each other, causing the RAM available to the application to gradually decrease because it cannot be freed.
