The dark side of hackathons

Posted on

In the previous part of this trilogy, I discussed several reasons to participate in hackathons. The motivation to learn a lot of new things and win valuable prizes attracts many, but often due to the mistakes of the organizers or sponsoring companies, the event ends unsuccessfully and participants leave dissatisfied. To minimize such unpleasant cases, I have written this post. The second part of the trilogy is dedicated to the mistakes of the organizers. This post is organized as follows […]

Why You Should Participate in Hackathons

Posted on

About a year and a half ago, I started participating in hackathons. During this time, I have taken part in more than 20 events of various scales and themes in Moscow, Helsinki, Berlin, Munich, Amsterdam, Zurich, and Paris.

For Ops, who are familiar with Kubernetes, launching a cluster and deploying an application is already a decent achievement. For Dev, the requests and […]

CJM for false alarm of the DrWeb antivirus.

Posted on

The chapter in which Doctor Web removes the Samsung Magician service DLL, declaring it a trojan, and to leave a request in the support service, you need not just to register on the portal, but also to provide a serial number. Which, of course, doesn't exist, because Dr.Web sends a key upon registration, and the serial number is generated during the registration process by the key — and is not stored ANYWHERE. […]

AI will control dogfighting in American fighters

Posted on

Artificial intelligence consistently outplays grandmasters in chess, bests champions in Go, shows prowess in poker tournaments, and easily defeats esports players in strategic games. However, AI still struggles to win in real combat situations, yet this is an aspiration, as stated by the U.S. Department of Defense's DARPA. Operating at high speeds under significant loads […]

The History of the Internet: Collapse, Part 2

Posted on

By approving the use of private microwave networks in "solution 890 or higher," the U.S. Federal Communications Commission (FCC) perhaps hoped to push all these private networks into their quiet corner of the market and forget about them. However, it quickly became clear that this was impossible. New faces and organizations emerged, insisting on changes to the existing regulatory platform. They proposed many new […]

LLVM from the Perspective of Go

Posted on

Compiler development is a very challenging task. However, with the advancement of projects like LLVM, solving this problem has become significantly easier, allowing even a solo programmer to create a new language close in performance to C. Working with LLVM is complicated by the fact that this system is presented with a vast amount of code, accompanied by scant documentation. In an attempt to address this shortcoming, the author of the material […]

Design Mail, mail… "Currently, any novice user can set up their free email inbox; they just need to register on one of the internet portals," claims Wikipedia. So, launching your own mail server for this purpose seems a bit odd. Nevertheless, I do not regret the month spent on this, from the day of the OS installation to the day […]
