It seemed that after the vulnerabilities Meltdown and Spectre discovered over a year ago, nothing could surprise fans and users of Intel processors anymore. Yet again, the company managed to astonish us. More precisely, it was the researchers of vulnerabilities in Intel's microarchitecture that surprised us. A new set of vulnerabilities collectively known as microarchitectural data sampling (MDS) threatens to put a halt to the technology of multithreaded computing or […]
As with most posts, a problem arose with a distributed service, let’s call this service Alvin. This time, I didn't discover the issue myself; it was reported to me by the client-side team. One day, I woke up to a disgruntled email about significant delays with Alvin, which we planned to launch soon. Specifically, the client was facing a 99th percentile delay in […]

At the beginning of this month, on May 3rd, a significant release of the 'management system for distributed data storage in Kubernetes' was announced — Rook 1.0.0. Over a year ago, we published a general overview of Rook. At that time, we were asked to share our practical experience with it — and now, just at this important milestone in the project's history, we are pleased to […]
The use of solid-state drives in the field of data storage is no longer surprising. SSDs have firmly entered the IT equipment landscape ranging from personal computers and laptops to servers and storage systems. Over time, several generations of SSDs have emerged, each offering improved performance, reliability, and maximum capacity. But the question of monitoring write resources […]
The future 'father' of Soviet cosmonautics, Sergey Korolev — in the center. His passion for aviation began in his youth when he joined a glider club. He will face many challenges ahead, but his youthful enthusiasm will stay with him for life. Note: the photograph has been colorized using a service from Mail.ru. Their neural network performed much better than, for example, […]
