Recently I ran into an issue that I've run into before, but it's one of those things you forget about when you're not dealing with it all the time.
I purchased a new laptop (HP dv9000t) a few weeks ago, and had to update some of the drivers. I went to HP's web site, and found the page for my system. Their site is well organized, and it's pretty easy to find what you're looking for.
As a heavy computer user, I used to have a lot of problems with my right wrist. I thought I was getting a serious case of carpal tunnel syndrome. I often had to massage my wrist, and I also used some interesting stretching techniques to help relieve the discomfort. I'd heard of people who needed surgery to correct the problem, and I thought that would eventually be my fate.
Then I realized there was something I could do about it. I've figured out a few things that have changed my life, and I have no discomfort any more. Most of my problems come from the mouse, and I really believe that's where most other people's problems also lie.
Every once in a while, a discussion about switching the Internet to IPv6 shows up somewhere. It's usually the same story about how on some date the world will run out of IP addresses, and the Internet will come crashing to a halt. Generally, these stories get it right because we really are running out of IP addresses. Unfortunately, switching to IPv6 is not simple at all, and it has nothing to do with technical reasons.
Uptime is a measurement of how long your computer has been running without having been rebooted or turned off. Your uptime shouldn't be longer than about 16 hours, maybe 18. You have to sleep sometime.
Unfortunately, many people never turn off their computers. Energy use is at an all-time high and is only increasing. While I'm not a dyed-in-the-wool environmentalist, I am opposed to needlessly wasting energy when doing so is utterly fruitless.
Some people need their computers on all the time, and there can be legitimate reasons for this. If you need to compile a large program overnight, go ahead. Rendering a huge 3D image? No problem. Need to encode a bunch of video files and want to run it overnight? Go for it.
