Since then, they have assisted digital forensics and computer incident response professionals in discovering traces of program launches, including malicious ones. Leading digital forensics expert at Group-IB, Oleg Skulkin, discusses what can be found using Prefetch files and how to do it. Prefetch files are stored in […]

An article has been published on the Hyperbola project wiki, discussing the issues surrounding the Rust language in the context of free software, as well as the need for development independent of the policies of Mozilla Corporation (a subsidiary of the Mozilla Foundation with an annual income of about 0.5 billion dollars). One of the issues discussed in the article is the fact that, unlike C, Go, Haskell, and […]
Among the numerous UPS options, the most commonly used in entry-level server environments are Smart UPS from APC (now Schneider Electric). Their excellent reliability and low prices in the secondary market mean that system administrators, without much thought, plug these UPS devices into racks and attempt to extract maximum profit from equipment that’s 10-15 years old simply by replacing the batteries. Unfortunately, not always […]
On February 13, we invite you to participate in an in-depth technical seminar dedicated to preparing local server infrastructure for the implementation of hybrid solutions by migrating specific scenarios to the cloud. During the event, we will examine, through a practical example, the migration of a large company, where Windows Server 2008 R2 is deployed both on physical servers and in a virtual environment with […]

Drew DeVault, the author of the Sway user environment and the Aerc mail client, humorously attempted to create an implementation of Git written in POSIX Shell. The idea arose after a debate about the complexity of Git's internal structure, after which Drew decided to demonstrate his points by writing a working version of Git in pure Shell within a day. During the process, Drew realized that he might have been a bit overzealous […]

In the Middle Ages, dark humor was cherished. This is why the art of epitaphs became so popular. Philosophical or amusing sayings for one’s gravestone were composed during one’s lifetime, and people often hired professional epitaphists. The tradition of writing epitaphs continues to this day. However, while they are written relatively rarely in our country, in English-speaking countries, writing something tearful or […]
I invite you to review the transcript of Alexander Sigachev's report on Service Discovery in distributed systems using Consul as an example. Service Discovery is designed to allow for the minimal investment of resources when connecting a new application to our existing environment. By using Service Discovery, we can maximize the separation of either a Docker container or a virtual service from the environment in which it operates. […]
