American Bulls

American Bulls was an interesting site I stumbledupon recently. Not sure what algorithms they are using, but comparing with the charts, they seem to be pretty good. Worth taking a look.

VMWare Workstation or Player RAM Issue under Disk Disguise

You might see the following error when starting your VM:

Operation on file *.vmdk failed.

If the file resides on a remote file system, please make sure your network connection and the server where this disk resides are functioning properly. If the file resides
on a removeable media, reattach the media.

Choose Retry to attempt the operation again.
Choose Abort to terminate this session.
Choose Continue to forward the error to the guest operating system.

This might cause a hangup or app crash - just decrease the RAM on the VM and try again. Helped me!

Desktop PC

Yes, I admit it, I am a geek, nerd (whatever you call it) and I do have a Desktop PC (and I am proud). I've been keeping its shell (antec 180) the same for the last 10 years or so, but the interior has been changing ever since from P2 days up to Socket 1366. One of the things that remain the same is my old HDDs. I recently (and finally) decided to build a RAID. Reading about it, RAID 5 seemed to be a good idea, where you get x-1 hard disk worth of space. You have a decent tolerance for faults, unless 2 HDDs crash at the same time (which is unlikely).

So I had a collection of HDDs separately living in the case. I designated 4 x 1.5 TB disks to become the RAID (called it RAIDer - cheezy I know). I also had another 1.5 TB and 0.5 TB as spare. I did a hardcore cleaning operation and filled the spares with all the data. Research lead me to using physical RAID cards for better performance but I used Intel's Storage Matrix solution. RAID formation reduced the 6 TB diskspace to 4.09, however, now I have the comfort of knowing that a disk failure will not be the end of the world. Highly recommended.
