Personally I prefer the 2004 Hubble Ultra Deep Field
Warmer picture (it's been my desktop background for the past 8 years), and the contrast and detail seem to be better (compare closer spiral galaxies) than the Extreme Deep Field. Lower noise as well.
The "exposure" time and sensitivity and science of the Extreme is impressive, but for viewing pleasure I'll take the HUDF.
Hitachi's (previously IBM's) Drive Fitness Test is the most thorough disk test I've used. It works on all makes, and has a "drive exerciser" that can loop a test sequence.
I've seen it find problems with drives that the manufacturer's own tools don't expose.
My policy is that if a drive survives 20 loops of the exerciser and then a full extended test that it's fit for production service.
He's an avid cave diver, spends his time exploring caves around Mexico, and works to preserve them.
He's also a NAUI instructor, which is how I know him. Got to spend a week learning from the best diver in the world (at the time), and he also is a really nice guy. He gets really serious when it comes to diving, though. I think you have to be a little crazy to do the things he's tried, but that doesn't mean you're stupid. He is well aware that every time he goes down, even with years of training, that he may not come back up.
A really remarkable guy, and it was an honor to learn from him.
1. We were running the latest version of Firefox
2. Acrobat Reader was fully patched (version 8, not 9. But, we have to leave the JS enabled)
3. Adobe Flash was up-to-date
4. Windows was fully patched
5. We have web filters
6. They got past 2 layers of IDS/IPS and 3 layers of antivirus scanners (different engines)
7. Users are NOT admins!!!
Since then, we have switched to a few new products and attempted to tighten things up even more, but these things have gotten incredibly complex. In one case, it was a triple attack. The Flash ad (0-day exploit) loaded an exploited PDF (0-day exploit) that took advantage of a 0-day IE exploit (keep in mind we use Firefox), which compromised the system. We have a nuke-from-orbit policy on any system we suspect has been infected, but what a waste of time!
It was hosted from a site in India. The user was on Yahoo's website (we've had 4 infections through Yahoo's ads). They did NOT click on anything!
Be very afraid!
But for now, yes..... [nearly] Impossible.
And, it only takes 10 minutes to setup. Try it!
Oh, and it's free (ad supported). You can pay $200/year or so if you don't want the ads. Their support is quick and they have an active user community.
I was on my way to high school and could feel/hear the result while driving my car. Lived in NW Houston at the time. Parents later said they thought it was an earthquake, although they knew it was not really possible due to the type of soil in the area. Discussed it with a few friends at school, and we dismissed it as a weird fluke, but found out the cause that evening on the news. We never would have guessed that's what it was.
I have no opinion on Dr. Kundt's theories, but I have anecdotal evidence regarding the gas explosion outside of Houston.
