There are plenty of services that give you weather information, but which of them should you trust? When I started cycling a lot, I wanted as accurate information as possible on the weather conditions where I was riding.

My first idea was to assemble a small DIY weather station with sensors and obtain data from it. However, I chose not to ‘reinvent the wheel’. To ensure that I had a source of verified data, I opted to use weather information that is used in civil aviation, namely METAR (Meteorological Aerodrome Report) and TAF (Terminal Aerodrome Forecast). …

Today, I am going to explain how to quickly deploy several virtual servers with different operating systems on a single physical server without much effort. This will enable any system administrator to manage the whole corporate IT infrastructure in a centralized manner and save a huge amount of resources.

Virtualization helps reach maximum abstraction from physical server equipment, protect critical services and easily restore their operation after serious failures.

Most system administrators are certainly aware of virtual environment techniques, so this article may not be a revelation to them. Nevertheless, some companies still do not use flexible and fast virtual…

Despite how new something is or how long it’s been working under a full workload, equipment sometimes starts to act a bit unpredictably. Servers are no exception.

Crashes and malfunctions happen, and oftentimes, what should just be simple troubleshooting turns into a time-consuming whodunit.

Below, we’ll be looking at a few interesting and curious examples of how servers have misbehaved, and what was done to get them back in order.

Identifying Errors

More times than not, issues are registered only after clients submit a ticket to tech support.

When our Dedicated Server clients contact us, we run a free diagnosis to ensure…
