The Cost of Being a M$ Shop

Published by Robert Pogson August 29th, 2010 in technology. 1 Comment

M$ is flaunting news of a customer migrating from VMware to Hyper-V virtualization on the server. The subject customer is a M$ shop and sees the major reason to switch being cost… If they were not a M$ shop but working for themselves they would see that KVM or VirtualBox would save them more money by far.

M$ charges only about $20 for Hyper-V as long as you pay them $1000+ for 2008 and the damned CALs.

VirtualBox and KVM cost $0 for the server licence and the hypervisor included. Users of GNU/Linux also save a bundle on re-re-reboots that are killing some in large deployments of that other OS.

Bootability

Published by Robert Pogson August 29th, 2010 in technology. 3 Comments

One of the lovely things about GNU/Linux is that it boots and keeps on booting. Compare that with that other OS that eventually becomes unbootable.

A very common boot-loader for GNU/Linux systems is GRUB. Lately, version 2 has introduced a lot of features and extended the region of the hard drive used. Therein lies a problem for “dual-booting”. Some apps or malware on that other OS have been storing stuff in the early sectors and just running that other OS clobbers GRUB2.

My advice? Don’t dual-boot. If you need to run that other OS, do so in a virtual machine so that it can clobber its virtual boot-loader and not yours. VirtualBox makes this very easy and you get the added benefit that you can run both OS simultaneously without having to re-re-reboot.

I did this on one system this year. The principal obtained a new machine with “7″. He wanted to try GNU/Linux. I set up VirtualBox to autostart with GNU/Linux booting in the virtual machine. He never used “7″ at all…

My Mission

My observations and opinions about IT are based on 40 years of use in science and technology and lately, in education. I like IT that is fast, cost-effective and reliable. I do not care whether my solution is the same as yours. I like to think for myself.

My first use of GNU/Linux in 2001 was so remarkably better than what I had been using, I feel it is important work to share GNU/Linux with the world. I have been blessed by working in schools where students and school systems have benefited by good, modular software easily installed in most systems.

I have shown GNU/Linux to thousands of students and hundreds of teachers over the years and will continue in some way doing that until I die in spite of the opposition.
