MySQL, Thread Caching, Linux and a busy site!

Heres an article that helped me with an issue over at a friends site http://www.ftatalk.com Their site was exploding and they need to tune out the current server as much as possible. One thing that I noticed was that MySQL wasn’t tuned properly. So After making some changes and finding out that there was no thread caching, I searched the web and found this article. Wow, it’s been a busy week. I was totally swamped for several days dealing with the remember.yahoo.com MySQL servers and related stuff. And then I used a day or two to recover (sleep, shower, etc). Anyway, I made some interesting discoveries along the way. The most surprising one had to do with thread caching on Linux when you have a busy MySQL server–busy in a particular way, mind you. Read the full article at jeremy.zawodny.com ***UPDATE*** I have moved ftatalk.com over to lighttpd and its doing wonders! You can also check out the ftatalk.com mirror at http://www.satfix.net I will also be writing an article about lighttpd and how it can help you get the most out of your hardware.

Boeing’s unmanned A160T Hummingbird helicopter takes flight

Not the first Unmanned aerial vehicle (UAV) made. But the Boeing A160HT Humming Bird should be one of the best once further tests and simulation in combat missions is completed.
Boeing's unmanned A160T Hummingbird helicopter takes flight -

Filed under:


It's been a few ticks since we've seen Boeing send an atypical aircraft into the friendly skies, but the firm's latest helicopter has successfully completed a 12-minute test flight without so much as a pilot on board. The A160T Hummingbird unmanned rotorcraft is a turbine-powered "warfighter" that aims to provide "intelligence, surveillance, and reconnaissance coverage" in locales that could make even the most calloused veteran queasy. During its time in the air, it reportedly met every objective set for it, and while we've no idea how soon this thing will be lifting itself up, it'll eventually reach speeds of up to 140 knots and stay airborne for up to 20 hours before returning to base for a pat on the wing.

Drupal Day 1

So, this is what Day 1 is like. I have a nice theme that I got off the main Drupal site. As you can see its sleep and colorful but not overwhelming. Aside from messing with the general configuration of Drupal, there is a lot more you need to do to make it even remotely functional/organized. Lets take categories for instance. At first I didn't know exactly how these worked. However after some playing around, and further posting. I was able to separate my blog entries and the HOWTO's. I just create a new Category for each, and then provide terms to place them under which is a great feature.
