Ironically, the fact that I am really into race sims (not GTA, but Gran Turismo et al) probably is what saved me in my first accident. I was rear-ended in the right rear at freeway speeds and sent into a spin. If I hadn't already had the muscle memory to recover from spins, I would have probably caused other collisions as opposed to being able to recover. I only ended up doing roughly a 720.
I was judged "not at fault" in the accident, and praised for paying attention in driver's ed...
I gotta disagree with using a cameraphone, since if you're doing something as cool as touring the world, you should at least carry a decent 5/6 MP camera:)
PDAs do more than ebooks - I haven't seen a decent language program or currency program for a phone yet. Maybe Europe has better ones than the US, but here they suck. Modern PocketPC PDAs can do automated backup to non-volatile memory, just so you know.
I agree with using the same cards between PDA/Camera. That's always nice, but sometimes financially impractical. When I was abroad I just carried 4 or 5 CF cards and a CF sleeve for my iPaq. (my camera uses CF).
When I've done long travel, I've tried to go as multi-function as possible.

That's really awesome, and obviously your systems are a great use for VMs:D
Our web stuff virtualized *beautifully*. We had few to no issues, but we ran into major problems when mgmt wanted to virtualize several of the other systems.
And since when is a warning about an unfixed bug moot? It's an *unfixed* bug in ESX Server Update 3. When it's patched in the standard distribution, then it will be moot.
VMs are still quite a new science (as opposed to LPARs) so there are lots of bugs still out there.
That's obviously just an example - uptime doesn't provide high-water marks, etc
Ahh, slashdot. People just *love* to split hairs:D
Ok, last time I'm saying this: BE CAREFUL. Not every system is an ideal candidate for virtualization, and even the ones that seem perfect at first glance can fail. Don't rely on only "overview" metrics. Do thorough inspection, and make sure you load test.
VMs rule, but there are gotchas and bugs that can be showstoppers. Just cause someone else has 300 servers running via virtualization doesn't mean you can:D
Very good point - and one I personally enjoy. Especially good when building a "Reference" system before imaging it out to other servers. Being able to clone 30 web boxes in minutes off a virtual is SO nice:D
"Modern processors are way overkill for most things they're being used for."
Right - except like I said - watch those spikes. We took a system that according to our monitoring sat at essentially 0-1% used (load average: 0.01, 0.02, 0.01) and put it on a virtual. Great idea, right?
Except for the fact that once a day it runs a report that seems fairly harmless but caused the filesystem to go Read Only due to a VMWare bug. The report lasts only about 2 minutes, but it hammers the disk in apparently just the right way.
It's the spikes you have to be careful of. Just look for your high-water-marks. If the box spikes to 90% or 100% (though the load average doesn't reflect it) it will have some issues.
Yes - we have quite a bit that we just put in here at my shop.
Virtualization good: Webservers, middle tier stuff, etc. Virtualization bad: DBs, memory intensive, CPU intensive.
Biggest issue? "Surprise" systems. You might see a system and notice a "reasonable" load average, then find out once it's on a VM that it was a really horrible candidate because it has huge memory, disk, CPU, or network spikes. VMWare especially seems to hate disk spikes.
What we learned is it's the not the average as much as the high-water-marks that really matter. A system that's quiet 99.99% of the time, but spikes to 100% for 60 seconds here or there can be nasty.
I recently got so fed up with being just a "cog in the wheel" that I dropped my WoW account, cancelled Steam, and went to a library. It's gotten so that the only place I can escape ads is in my own head.
I'm in the same boat - I don't *like* AD, but I don't hate it either. I'll play with my OSX stuff a bit, see what functionality I can tailor. I'm all for going with a real LDAP given the opportunity.
Pilots don't fly multi-month missions. They tend to have short term, results-oriented personalities.
Scientists? Like the ones that have done so well on all those extremely long Bio-Sphere missions and such? Oh - wait - they haven't.
I'm not talking about whether people are smart, or capable, or able to do brilliant research. I'm talking about handling the tedious monotony of 2 month long patrols without surfacing. Dealing with crap from supervisors with no possible recourse. Living in quarters so tight that your idea of personal space is what's inside your uniform.
Sub duty is not a party or a quick jaunt around the planet for a week or two. It's not even like being on a carrier where you have sunrises, sunsets, fish, fresh air, etc. It's a tight, cramped, cold, noisy little space unto itself.
Yup - and I think I paid about that for Ultima on Apple II :)
That's why things like DOOM ($35?) were so nice.
I guess some things never change.
Yup - you sure know better than a police officer, 2 insurance adjustors, and a judge reviewing the footage from the overpass camera.
Thanks for sorting that out.
Yup - cause, ya know, everybody knows that's the best way to play a racing simulator ;)

That's a good set in my experience.
Greenpeace is an eco-terrorist group. They do things like ram whaling ships and such.
Yup - violence never needs a reason.
Photoshop and Oblivion at the same time? Dude, you must have a LOT of RAM :)
I respect that (oh, but as per your sig...) you asshat.
Awesome Ultima ref :D
Swamp boots FTW
So, the iphone with USB, 2MP, 8GB storage, and what appears to be an SD card slot, and the MP3 player would be ideal?

Our case was Guest FS on ESX server Update 3 (though we were able to mostly fix it by moving the SAN drivers to Update 2)

Hehehe - please do :D
"This dude on this web forum said DBs suck on VMs"
Let me know how that works for you

I recently got so fed up with being just a "cog in the wheel" that I dropped my WoW account, cancelled Steam, and went to a library. It's gotten so that the only place I can escape ads is in my own head.
Seems like it's actually *harder*, to process and *easier* to forge though, not easier. Or am I the only one that thinks so?
While I respect that... would such a person need a step by step guide to alter their hosts file?
Actually on OSX:
/etc/hosts
sudo bash
echo "208.65.153.253 www.youtube.com" >>
(can't just su on OSX usually - root has no password)
I agree - it was the same here. OSX standby/sleep works better than Vista, XP, Fedora, and Ubuntu.
:) OO.o, X11, ssh, perl, Vim, gcc, java.
Not perfect, but better.
Ironically, about 50% of what I use a mac for Linux would do better

I actually really liked that, so I hope to play his new project if that's the case
