Freelance developer for the last six years, I'm specializing myself in quality and productivity for the last two years. I spent the last year working in a Dilbertesque company, watching people doing everything they can to make projects fail.

For a long time, I worked with Microsoft technologies, but recently started to build Linux-based DevOps infrastructure—an excellent way to learn lots of new things.

I'm mostly active on Programmers.SE, but try to participate on other sites as well.

Do you want to:

@Jonathan: This doesn't explain why 1 + 1 equals 0.5.

@FrederikDeweerdt: the equipment in the middle is a switch which should be able to handle a 2 Gbps connection correctly, I suppose. I edited the question to provide more details.

comment Why datacenter water cooling is not widespread?
It looks like you're new to Stack Exchange, so welcome. Note that unlike forums which welcome discussions, Stack Exchange is oriented towards objective answers based on expertise. Data centers are hugely expensive and it's time consuming to set up thousands of machines anyway. Talking about space, water cooling can easily be set up in an 1U. Since you compare a server to a gaming PC, do you know what blades are or what high density computing is? As for "decent ventilation/70°F airflow", you have never visited a data center, right?

comment Why do I lose network connectivity for a virtual machine outside /24?
Looks like 255.255.252.0 is the right answer: I can ping the virtual machine, and it can ping the switch and the real server. I still don't understand why /22 instead of /23.

comment Why do I lose network connectivity for a virtual machine outside /24?
@joeqwerty: I'm sorry, I don't understand why. As I understand it, /22 corresponds to 255.255.252.0, while 255.255.255.252 would be /30. Also, why /22 if I only need 512 addresses? I've read How does IPv4 Subnetting Work?, but still don't get it. Can you please explain it in more details in an answer?
