kentavr009 @ Habr 1 place · 04/24/2025 02:04 EDT

One could write, “Experienced developers working on parsing and automation often face the need to bypass modern CAPTCHAs.” But that’s too boring… I’d rather start like this—continuing to explore the amusing world of CAPTCHAs, I finally stumbled upon the Chinese variant of protection: the GeeTest CAPTCHA. Let’s break down what this beast is, where it dwells, and why you should (or shouldn’t) fear it… You’ll understand as we go!GeeTest is... Read more ›

Horsehead Nebula

klimkovsky @ Habr 2 place · 04/22/2025 23:36 EDT

The whimsical image of a chess knight in profile among the stars is perhaps the most recognizable among deep space objects. It can be said that the Horsehead Nebula tops the recognition rankings among nebulae and galaxies. Perhaps the Andromeda and Orion Nebulae resonate more with the general public, but only specialists and advanced amateurs know what they look like. Even among them, there are often cases when the famous... Read more ›

Rosette Nebula

klimkovsky @ Habr 3 place · 04/22/2025 23:06 EDT

The large but sparsely populated constellation Monoceros, barely visible to the naked eye, can take pride in hosting an extraordinary treasure: the Rosette Nebula. Monoceros is a relatively recent addition to the star map. Lacking bright stars, astronomers of the pre-telescope era deemed this region unworthy of a constellation. After all, how could a constellation exist without luminous stars? A few 4th-magnitude stars hardly suffice to form a recognizable figure.... Read more ›

Carina Nebula

Add to bookmarks Don't show Habr

klimkovsky @ Habr · 04/22/2025 22:57 EDT

The term "Carina Nebula" is sometimes translated as "Nebula of Carina," evoking the image of a beautiful female name. However, this is a misinterpretation. "Carina" is Latin for "keel," referring to the keel of a ship—not just any ship, but the Argo, depicted on ancient star maps. Over time, the Argo constellation was divided into several modern constellations: Carina, Puppis, Vela, and Pyxis (Compass). The stars of the Argo are... Read more ›

Admit it, how many times have you wanted to quickly create an image for a post or presentation, but instead got stuck in an editor or endless searches for a suitable image on Google? Wouldn't it be great if the picture in your head could just appear instantly? Time is money, inspiration is on pause, and that's where AI comes to the rescue.

Выпущенные в прошлую субботу Llama Scout (17 миллиардов активных параметров, 16 экспертов, 109 миллиардов параметров суммарно) и Llama Maverick (17 миллиардов активных параметров, 128 экспертов, 400 миллиардов параметров суммарно) выглядят крайне разочаровывающе. Они разочаровывают настолько, что пользователи даже предполагают причиной неправильную конфигурацию; они задаются вопросами и спорят о том, насколько сильно манипулировали бенчмарками.Это был самая негативная реакция на выпуск модели, совершенно пр Read more ›

[Translation] Custom structure serialization in Unreal Engine

Add to bookmarks Don't show Habr

MMadmer @ Habr 1 place · 04/13/2025 01:00 EDT

Let’s say you’ve created your own USTRUCT in C++ and now you want to serialize it.Usually, it’s enough to simply mark the desired fields with SaveGame. But here’s the problem — in order for this to work, the fields themselves must support serialization.Unfortunately, one of our variables doesn’t.In my case, it’s a struct called FNonSerializableStruct. Because of that, only the second struct gets serialized, even though we marked both with... Read more ›

The Armenia Opportunity: EDA, ASIC, FPGA + connections with USA, China and Russia

Add to bookmarks Don't show Habr

YuriPanchul @ Habr 2 place · 04/12/2025 04:13 EDT

Armenia is a lucky country. Back in the 1990s somebody lobbied Synopsys, the #1 leader in the Electronic Design Automation market, to create a division there. It was joined by Mentor Graphics / Siemens EDA, another EDA leader, then NVidia. Synopsys Armenia became the largest Synopsys division outside the US Silicon Valley and Boston, although the Taiwanese may tell you otherwise. Since Synopsys and Mentor make software used by chip...

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

Add to bookmarks Don't show Habr

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...

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 ›

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. It is capable of analyzing user behavior and blocking suspicious activity,... Read more ›
