Some people that try to explain 64 bit performance will simply say “64 bit is faster”. That is incorrect. Though the actual results may make that appear to be accurate. Think of your computer as a multi lane highway. The I/O path (Processor, System bus and RAM) limit the number of lanes (32 or 64bit)… Continue reading High Performance Computing. Part 1 of 2. Why 64 bit operating systems outperform the 32 bit versions.

Windows 7 Ultimate 64 bit edition VS. Fedora 11 64 bit edition
To keep it simple I’m referring only to the versions in the title of the post unless otherwise noted. Initial Cost (retail and otherwise) Windows $99-349 Fedora $0-$59 Speed about equivalent for both. Minor variances on this or that but overall not significantly different for everyday tasks.

GRUB2 Ongoing …. and Outta there!
I was wholly unable to get GRUB2 (v1.96) to perform everything I needed at the same time. I have spent a good portion of the last two days trying. I needed it to be able to boot to ext4 partitions directly. This it performed with ease. I need it to boot to three operating systems.… Continue reading GRUB2 Ongoing …. and Outta there!

Yesterday I installed Kubuntu 9.10. The process was fairly straight forward and painless. Then I went to my /boot/grub folder, searching for menu.lst to update with all the proper partitions.

Windows. Why do I still use it?
I just received an email from an old friend after reading today’s post about Fedora. He said “You still use Windows, don’t you?” I replied in the affirmative. I do still use Microsoft Windows Operating Systems. There are only two reasons. 1) I need to be able to support my customers and clients that prefer… Continue reading Windows. Why do I still use it?
Reasons Fedora may be of interest.
1. Security. You will not need to worry about 20 new viruses, worms, trojans or malware programs every day for Fedora. There are very few of these to worry about with Linux. 2. Price. Free for the Download. You do not have to pay for Fedora, EVER. Visit Fedora’s Site. This is also true for… Continue reading Reasons Fedora may be of interest.
Windows 7 Hype
There seems to be quite a lot of this around today. Various news sources are ramping up the fufara and fanfare for or about Windows 7. I have installed the Release Candidate of Windows 7 on my QX9650 powered workstation. I am not terribly impressed. Windows Vista and Windows 7 have a feature called Relibility… Continue reading Windows 7 Hype
Slow browsing
If you are experiencing really slow web browsing but downloads seem to be at normal speed, you may be a victim of a DNS (domain name service) cache poisoning attack. This can affect any operating system connected to the Internet. Many of my professional clients have been impacted by this recently. It is becoming a… Continue reading Slow browsing
