Comment: Sell Data Center Servcies (Score 4, Interesting) 305

I suppose what the article means is that there are 4 x 48U racks installed in the server room. It is fiction that each rack could actually loaded with 48 x 1U servers! Potential problems are: cooling, weight, air (fire hazard), power supply.

Most likely actual rack usage looks as follows:

- Rack with 5 Servers
- Rack for Patching and switches
- Rack for phone system / phone patches
- Rack for backup.

If they have remaining capacity, they could rent it out/sell to other community organisations.

Comment: Virtual shared server with "Best Effort" SLA (Score 1) 539

Sound to me like the poster uses a virtual shared server, ie. The hosting company provides a virtual root environment, this would be an explanation why they can "root" the server, ie. just access the file system directly from the hypervisor. I am sure this kind of service does not include uptime guarantees, it operates most likely under "Best Effort" promise. Which means they do not need to guarantee either uptime or availability. Their monitoring system and logs do not detect any error, so they want to check the posters systems logs - a reasonable request as they are trying to help him. Monitoring is a difficult task - what to you measure, where is your sensor. Was the outage on your own internet connection rather than on the server? "Moments ago, there were three simultaneous outages while I was logged into the server working on some projects. " It sounds very suspicious, like the admin interface causes interruption in the VM. Something like this happened to my VMWare Servers totally unexplainable, but reproducably.

Its a silly argument that the article makes. E-Readers can display B&W pages, and gray shades. This is absolutely sufficient for displaying textbooks. There is a line of extremely bloated textbooks that takes liberties with layout and colour. I just wonder for what purpose colour is used in those books. In my opinion it does neither help understanding of diagrams and models, nor does it improve the information density. Perhaps a revisit of Tufte's rules for information design is in order for publishers?

We all like praise, but a hike in our pay is the best kind of ways.
