[Translation] GeeTest CAPTCHA Recognition: How to Bypass a Sophisticated Anti-Bot System

One could write, β€œExperienced developers working on parsing and automation often face the need to bypass modern CAPTCHAs.” But that’s too boring… I’d rather start like thisβ€”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 β€Ί

Horsehead Nebula

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 β€Ί

Rosette Nebula

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 β€Ί

Carina Nebula

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 shipβ€”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 β€Ί

[Translation] Custom structure serialization in Unreal Engine

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 β€” 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 β€Ί

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

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...

Historically, we’ve ended up using a few rather obscure PHP extensionsβ€”written and barely (if at all) maintained by their original authorsβ€”that aren’t available in standard Debian package sources.We stick to the principle of β€œdo 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 extensionsβ€”without breaking compatibility with the existing...

[Translation] A Tale of How Not to Turn Your Cisco Router into a Public DNS and NTP Server by Accident

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 β€Ί
