Reversing and cracking external self-encrypting drives has been a longtime hobby of mine. In the past, I have had the opportunity to practice with models such as Zalman VE-400, Zalman ZM-SHE500, Zalman ZM-VE500. Just recently, a colleague brought me another exhibit: Patriot (Aigo) SK8671, which is built according to a typical design - an LCD indicator and a keypad for entering a PIN code. Here's what came out of it… 1. Introduction […]
Research work is perhaps the most interesting part of our training. The idea is to try yourself in your chosen direction while still at university. For example, students from the areas of Software Engineering and Machine Learning often go to do research in companies (mainly JetBrains or Yandex, but not only). In this post I will talk about my project in Computer Science. […]
Hi all. Colleagues recently wrote on this blog that registration for the next Interface Development School in Moscow has opened. I am very pleased with the new set, because I was one of those who came up with the School in 2012, and since then I have been constantly involved in it. She has evolved. From it came a whole mini-generation of developers with a broad outlook and the ability to […]

And what to do if it gets drained. According to our internal statistics, last year 656 publications out of 16711 went negative. This is slightly less than 4%. About half of them […]
“Jetpack pilot” is a “profession of the past” and is 60 years old. "Jetpack Developer" - 100 years old. “Instructor of a school course on designing jetpacks” is the profession of the present, we are doing it now. What is the profession of the future? Tamper? Archaeoprogrammer? Designer of false memories? Blade Runner? An old friend of mine who took part in crowdsourcing a jetpack engine has now launched his […]
The European Nuclear Research Center is going to abandon all proprietary products in its work, and primarily from Microsoft products. In previous years, CERN actively used various closed-source commercial products because it made it easy to find industry experts. CERN collaborates with a huge number of companies and institutes, and it was important for him to make […]

In September 2019, St. Petersburg State University opens the Faculty of Mathematics and Computer Science. Enrollment for undergraduate studies begins at the end of June in three areas: “Mathematics”, “Mathematics, algorithms and data analysis” and “Modern programming”. The programs were created by the team of the Laboratory named after. P.L. Chebyshev together with POMI RAS, Computer Science Center, Gazpromneft, JetBrains and Yandex companies. The courses are taught by renowned teachers, experienced [...]
