Hyperthreading on a Dell GX280

I have a noisy Dell GX280 at work and I was looking for solutions to the issue when I ran across the toggling of the hyperthreading option in the BIOS as a possible solution. It turns out that hyperthreading is turned off by default and it wsa reported that either turning it on or off results in the quieting of the PC. There were conflicting reports on this so I decided to try it.

It didn't work.

What it did do, however, was allow me to multi-task to a greater degree when I have a single process that is consuming a great deal of processor cycles. I found that a processor-intensive application will not slow down my ability to check email with Outlook or surf the web with Firefox to any great degree. As processor- and memory-intensive as these applications are I found them to be much more sluggish under the conditions I have described when hyperthreading was turned off. In fact, this quick synopsis of hyperthreading technology from Dell corroborates my experience.

tightvnc keyboard mapping problem in Ubuntu 9.04

Image
I have been, off and on, having an issue with the keys on my keyboard mapping to the correct values when using the tightvnc client when paired with the vncserver vino in Ubuntu 9.04. I am not exactly sure what keyboard layout the client and server was expecting, but it seemed like every time I restarted the OS the keyboard mapping problem would come back and I would be at square one again. Well, I think I have found the workaround I was looking for . Hopefully this will help anyone else that is having this issue.

The manifestation of the "I" and the gift of self - Part 1

I am continuing my journey through Pope John Paul II's Theology of the Body and I had never realized how body-focused the 2nd and 3rd chapters of Genesis truly are.  But then it all makes so much more sense when it was brought to my attention that the body we have been given in a manifestation of me, or to put it another way, the "I". And it goes beyond that still. Not only does it reveal me, but my body also reveals, in no small measure, the image of God. That is not to say that God is made of flesh like me as is depicted in so many Renaissance paintings. The old man in the sky is nothing like the God as revealed in the Bible. However, the love that God is, the holiness that he is, the justice he is, the righteousness that he is...all of it is shown to the world through my body. In a very real way, my body allows for others, and for me, to participate in the mystery (the hiddenness) of the image of God. That is by design; from the beginning.  If God is revealed in nature...

Let me learn what I need to learn

In the “I don’t know what God is trying to produce in me…” portion of the blog: I work across (not with) an incredibly loud person. We are in cubes and he refuses to use a handset when he is in a conference call…or headphones. Everything is done via speaker phone. Maybe his handset is broken? I don’t know and am too timid (read “interested in keeping the peace”) to ask him. Of course he shouts into his speaker phone as well when he talks. Now he even refuses to use a keyboard. He has a speech recognition program that allows him to speak to the computer rather than type. Good for him! Now we can all hear “Comma…open parenthesis…close parenthesis…tab…tab...tab…” Was it my sin or my parents sin that relegated me to this placement in the office. We all know the answer to that but man…it sure feels like I am getting punished for something.
