Many have noticed that among millionaires, there are many Jews. And among high-ranking officials. And among prominent scientists (22% of Nobel laureates). This means that Jews make up only about 0.2% of the world's population, but they are significantly more represented among the successful. How do they achieve this? What makes Jews so special? I once heard about a study from an American university (the link is lost, but if anyone can […]

GOSTIM: P2P F2F E2EE IM in one evening with GOST cryptography

As a developer of the PyGOST library (GOST cryptographic primitives in pure Python), I often receive questions about how to quickly implement a basic secure messaging system.

ASN.1 is a standard (ISO, ITU-T, GOST) for describing structured information, as well as the rules for encoding that information. For me as a programmer, it is just another format for serialization and data representation, alongside JSON, XML, XDR, and others.

Posted on

This article discusses a case on speeding up a browser application by replacing JavaScript computations with WebAssembly. What is WebAssembly? In short, it is a binary instruction format for a stack-based virtual machine. It is often referred to as a programming language (abbreviated as Wasm), but that is not correct.
