Cabling as a solid part of data center infrastructure

Whatta irony? I've just said that one cannot think about work related issues during free time, when suddenly I discovered an interesting white paper on data center cabling: "Data Center Cabling Considerations: Point-to-Point vs Structured Cabling" by Siemon. Therefore, I had to write another blog post this week, as my thoughts are now influenced by the lecture.

Hatari on GNU/Linux. Virtualization made funny

It's not good to think about professional work issues all the time, therefore people used to have some hobbies. One of them, quite popular between IT guys, including me, is retrocomputing. I like collecting interesting machines from the past, but also I find it relaxing to play them in my spare time, including some simple coding. Therefore, as between Christmas and New Year's Eve many of us have some spare time between family related events, let me present Hatari – the great emulator of 16/32-bit Atari computers available for GNU/Linux. Good starting point for future explorations.

It consists of many subsystems and has it's own place in the foundation of organizational IT architecture, yet all these subsystems are cooperating to provide services for upper layer in the whole IT infrastructure. So, if it's a system, could we have more control over it? Do we need DCIM (Data Center Infrastructure Management) solutions? Or maybe we should rather think of having real Data Center Infrastructure... Operating Systems, integrating all the controls in one place for data center operators?

Is it possible to over-maintain your data center?

Well, I believe that periodical maintenance of critical data center infrastructure components is crucial for reliability. Am I wrong?

Minix! Do still waters run deep into embedded systems market?

This is not directly data center related, but – come on – this blog statement is: "IT's all connected, even if IT's not", so... Today? Minix vs Linux conflict! Who remembers these old discussions, full of emotions, that were going on the news groups (comp.os.minix) at the beginning of the nineties (1992 exactly)? Honestly, I don't remember. I didn't have an access to the Internet then and I was using snail mail for software swapping these times, mainly (demoscene stuff, quite a different story anyway, so let's skip it this time).
