Nope, you're right, that works just fine. You don't actually need the DMZ, and you can also use SSH tunnels if you want a more adhoc environment (that's what I'm doing now).
The problem is that most people just take the stuff out of the box and plug it in, leaving themselves open. This article describes the problem.
We can set this up easily enough, but for most people, if it isn't configured by the manufacturer, it will never happen. Even some of my more technically capable friends never upgrade firmware (or manage to destroy their equipment when they try).
If aircraft are Internet connected, they should have webcams installed around the cabin sending time-lapse images to the ground (tunneled for security). The cameras don't have to be visible (and probably shouldn't be).
If they're going to disarm all the passengers, preventing/limiting their response to a problem (hey, I'd just as soon have child-proof Mace cannisters at each seat), then at least the ground will be able to "tune in" and monitor aircraft. It would also help identify those causing a problem.
This isn't a privacy issue; you don't have any expectation that no one can see you when you are on a plane, especially airline personnel.
Comparing gun related deaths in the USA to other countries doesn't mean anything. How about bicycle related deaths? Cell phone caused car accidents? Food poisoning deaths? How do they fair in Eurpoe, Australia, New Zealand and Asia?
The Center for Disease Control (http://www.cdc.gov) has death rate statistics. It helps keep things in perspective, when you can look at actual numbers.
Taken as an absolute, gun deaths look pretty bad. But you have to remember that the USA is a large population (about 280 million), so even a small percentage is a big number. When compared to much more trivial causes of death, the numbers don't look so bad.
I actually start to wonder why (aside from the emotional issues, obviously) people are dedicating so much attention to one cause of death, when there are so many others which are more significant (if saving lives is the goal, and I assume it is).
I converted my two nephews systems to Linux. Their major complaint was that they couldn't figure out how to install games (even Linux games) by themselves. I figured that was a good thing considering their age (11 and 6).
It's just something that you have to be prepared for, if you go down this path.
I gave my prior employer my rate, and they decided that it wasn't such an emergency after all. In reality, they just thought they could get me to do the work for cheap since I was so familiar with the subject matter. It turns out they already had another contractor give them a similar price.
If you did the work for them for free, then the ploy worked. I'd guess it probably does, most of the time. Remember, this is business, the thing that keeps you and your family eating.
Unlike Flex-ES, Hercules/390 can't run VM/ESA (it can run VM/370, however). VM/ESA (or z/VM as it's currently called) requires a super-instruction used to run a virtual machine, SIE (Start Interpreted Execution) which is not implemented in Hercules/390.
Before there were MP3 appliances, people were trading MP3 files. If you only trade Ogg files, then manufacturers will do what they always do: supply the demand.
Why not just subscribe to a good USENET server? Most of the television programming that's of any value gets posted within 24 hours of broadcast anyway. That way you only have to be concerned with the download speed, and can save the cost of the satellite equipment, PC and upload link.
I use a suction vac with a soft brush to remove dust from the screen, keyboard and any openings first. Then wipe the screen and any dirty areas (palm rest, mouse buttons, heavily used keys) with alcohol wipes (I use ReliOn Alchol Swabs available at local pharmacies for about $2/100).
The vacuuming first is important; it prevents the dust caking when wiping with the alcohol (makes the screen look smeared).
The laptop fan also tends to suck in dust; laptops are "heat challenged" as it is. Use the suction vac on the air inlets and exhaust for the fan to remove as much as possible.
I've been using this technique on both laptops and desktops with no problems for about 5 years now.
For the same reason you "code in C" or "code in Pascal" or "code in BASIC". The common use terminology has always (well, for the last 30 years) been to code in the . So you "code in assembler".
According to the directory listing, that photo is from March 15,1999. I know it takes a while until submitted articles are posted, but this seems a little excessive.
Visio already runs under WINE, along with the rest of MS office. I don't use it (native Linux apps meet my needs), but I did install it for just such a question:-)
...Was to have a mandatory 1 credit course for the seniors in the Computer Science degreee program, that required students to provide tutoring to others. Twice a week for two hours I sat with people that were having problems. Everything from teaching them to debug their coding assignments (not doing them for them), to explaining concepts covered in class.
Frequently, the problem was just a small missing piece in their understanding. It was great to see the light come on in their expressions when they got it.
I enjoyed the experience a great deal, and now 25 years later, I still find it very rewarding and mutually educational.
Odds are in this type of environment, the buildings share a power transformer. If not, the power company may be willing to insert a bridge (capacitor).
The equipment is inexpensive, and every outlet becomes a network connection point. See Cringely's 8/15/02 article on the subject.
This problem keeps coming up; well meaning individuals that find a problem are then punished for their attempt at a good deed.
Without some protection for these individuals, no one will report problems for fear of legal entanglement. This obviously leaves the establishement exposed to those that do have less altruistic motives.
It sounds like something that Homeland Security should be taking on, that would actually have a benefit to our country's security.
I did read the article, but I missed that statement. it seems to me to make even less sense; what's the purpose of the wrist device then?
A small decypted (volitile) cache is similar to a filesystem cache. If properly implemented, no re-encryption is needed, just flush it, right? Otherwise you have unwritten data in a volitile store (bad for most general applications). If the cache is nonvolitile, that's back to the security risk on loss of power.
If my understanding is correct, just set the max age in the cache to a reasonable value and you can get rid of the wrist device.
There's no way that they are going to encrypt everything in a reasonable amount of time (even just an xor would take forever on a 40GB drive), and if they did, there's no way they could decrypt it fast enough on your return.
The implication is also that data is in an unencrypted state for some period, a risk in itself (just pop the battery when you take the laptop, remove the hard drive and attach to another system to see what's unencrypted). An encrypted filesystem seems more appropriate if you are really concerned about security.
I just recently completed a port (a consulting job) of some MSDOS Fortran IV to Linux Fortran 77 (about 65K lines).
The interesting thing is that I wasn't ever a big fan of Fortran, and never used it much. In fact I haven't written a line of code in Fortran in over 15 years.
However, it literally took me only a few minutes to "come up to speed". The language is very clean, readable and maintainable. I wonder if anyone will be able to say the same about current languages in 15 years.
I've seen both terms used... Search groups.google.com for:
"meta device" linux or metadevice linux
The source says "multiple device", so you're right; I'll use the correct terminology going forward. Thanks for pointing that out!
Re:What is your reason for wanting RAID?

Notebooks w/ RAID?

I use software RAID on Linux; the reason I'm looking for it on a notebook. Performance is excellent and CPU load is negligible (even on an old PPro200) even during intensive I/O bound operations. You can mix RAID0 for performance/capacity and RAID1 for reliability on the same pair of drives (different partitions), providing exceptional flexibility.

Now I can't buy anymore CDs, whether the music industry likes it or not. Which of us is going to blink first?
Couldn't this technology be combined with mesh network technology? Instant cellular replacement, just add handsets.

Yes, and strangely enough, it's called Evolution. :-)
