Nearly two years after the start of Russia's full-scale invasion, Ukrainians are beginning to ask themselves: "How long will this war last?". The uncertainty and the chance that the fighting will continue for years are weighing on civilians and sometimes even on the military.

In blynk we have one very hot code execution path. And now, after many years of optimizations, we end up by replacing "switch" statements with "if" conditions. That change alone allows us to save up to ~10 nanoseconds per call. So for 100k req/sec it saves us 0.1% of CPU :)

The current champion of JSON parsing is the AMD Ryzen 5 9600X 6-Core (5.5GHz). It is a $280 CPU. It can scan JSON at 12 GB/s. The closest Intel CPU on the current ranking is the Intel Core i9-11900K which gives you 7.5 GB/s. The i9 is a significantly more expensive CPU (>$450).

A fresh story on Forbes covers the first 1,000 drones built entirely with components manufactured in Ukraine. These drones were assembled by Vyrij and equipped with Kurbas-256 cameras made by Odd Systems. Today, Odd Systems is the only Ukrainian manufacturer of thermal cameras

On “negotiations.” It is important to finally call things by their proper names. What russia calls a “peace process” is in fact a separate special operation against the West. Its goal is not to end the war, but to force the United States and Europe to pressure Ukraine, while
