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 βΊ

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 βΊ

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 shipβnot 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 βΊ

Letβs say youβve created your own USTRUCT in C++ and now you want to serialize it.Usually, itβs enough to simply mark the desired fields with SaveGame. But hereβs the problem β in order for this to work, the fields themselves must support serialization.Unfortunately, one of our variables doesnβt.In my case, itβs a struct called FNonSerializableStruct. Because of that, only the second struct gets serialized, even though we marked both with... Read more βΊ

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, weβve ended up using a few rather obscure PHP extensionsβwritten and barely (if at all) maintained by their original authorsβthat arenβt available in standard Debian package sources.We stick to the principle of βdo it right, and itβll work right,β which means Slackware-style dropping binaries into the system outside of package managers is frowned upon.So instead, weβll be building proper .deb packages for PHP extensionsβwithout 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 donβt think things through, the router may start "living its own life" and end up, for instance, as a DDoS amplification tool. Letβs dive in Read more βΊ

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 βΊ
