The story of one small project twelve years long (about BIRMA.NET for the first time and frankly first-hand)

Submitted by

The birth of this project can be considered a small idea that came to me somewhere at the end of 2007, which was destined to find its final form only 12 years later (at this point in time - of course, although the current implementation, according to the author, is very satisfactory) . It all started with the fact that, in the process of fulfilling his then official duties in the library […]

Schrödinger's trusted boot. Intel Boot Guard

Submitted by

We propose to go down to a low level again and talk about the security of firmware for x86-compatible computer platforms. This time, the main ingredient of the study is Intel Boot Guard (not to be confused with Intel BIOS Guard!) - a hardware-supported trusted BIOS boot technology that the computer system vendor can permanently enable or disable at the production stage. Well, the research recipe is already familiar to us: [...]

Notes from a Nerd: Framework of Omnipotence

Submitted by

From the author I composed this sketch some time ago as a kind of creative rethinking of the story that I presented here, as well as its possible further development with some free fantastic assumptions. Of course, all this is only partly inspired by the author’s real experience, making it possible to try to answer the question: “What if?..” There is also some plot connection to my […]

Hackathon in a small company: how to arrange without dumping a load of resources

Submitted by

This article is about the first time I ran a hackathon for a team. Experienced organizers will probably find the material too simple and the story naive. I was targeting those who are just getting acquainted with the format and are thinking about whether to organize such an event. HFLabs does complex things with data: we clean and enrich customer contacts for large companies and build customer databases of hundreds of millions of records. 65 people work in Moscow offices, with about a dozen more working remotely from other […]

Video diary about the reunion of the devastated world in Death Stranding

Submitted by

Another short video diary has appeared on the Russian PlayStation channel, in which Hideo Kojima talks about his new creation - the post-apocalyptic adventure Death Stranding. Let us remind you: a video was previously released dedicated to the key theme of connections in the game, which even influenced the creation of the Kojima Productions studio itself.
