It is reported that the vulnerability enables a MITM (Man-In-The-Middle) attack. This occurs if an attacker is in the […]
We have long been accustomed to the fact that large IT companies engage not only in product releases and service provision, but also actively participate in the development of internet infrastructure.

We are now on the verge of a new era of cloud computing. I don't quite understand why we refer to remote server computing as 'cloud'. Of course, we should remember ruvds, which launched a server on a balloon and Microsoft with a data center underwater, but in reality, we live 'next to' servers, which will soon become our primary means of computing. What […]

At one point, we thought that the phrase 'server in the clouds' could be taken literally. So let's actually launch a functioning server into the sky that can be pinged! At first, the idea seemed crazy, but after some consideration […]

Friends, as you already know, we are working hard on a new geek project — "Server in the Clouds 2.0", or "Space Data Center". In short: on April 12, we will launch a DIY server on a stratospheric balloon at an altitude of about 30 km, we will transmit data to it through a space communication system, and from the server, we will broadcast data to Earth via radio communication. And […]

Recently, we have had a lot of content for mid-level and senior developers, but this episode is definitely for juniors. The main topics: What knowledge does a beginner programmer need to engage in web development? What do […]
