On SSDs, the tables used for wear-leveling get fragmented over time. One trick that works with almost all SSD models is to do a sequential write of every logical block, _twice_. That will result in unfragmented tables. It might work on thumb drives too, but remember to do it twice. Try this:
dd if=/dev/zero of=/path/to/usb/drive
dd if=/dev/zero of=/path/to/usb/drive

I am doing exactly what the OP wants to do. I've been living in my RV (29' 5th wheel trailer) for 6 months, and I'm typing this post over my satellite connection from the northern Cascade mountains in Washington. Here is what I have learned:
1) Satellite is the only way to go when you get out in the boonies. When we started this trip, I had an Openmoko phone as a backup ISP, but I dropped the data plan 2 months later because I almost never had connection.
2) Hughesnet is the only affordable satellite provider. Some other companies resell Hughesnet service. I use Motosat, which caters to the RV market. You will probably have to use a reseller, as Hughesnet's own TOS doesn't allow mobile use and they don't want you as their customer.
3) You can get an ordinary residential Hughesnet dish and mount it on a tripod, but aiming that dish is a royal PITA. www.maxwellsatellite.com sells dish, tripod, and pointing gear as a combo for IIRC $500. But it's still a PITA to point (the record holder from their user's group did it in 5 minutes), and vulnerable to theft. I wouldn't consider it an option if you are going to be moving frequently. A better setup is a roof mounted tracker, like what Motosat makes. Their motorized, and usually acquire the satellite in under 5 minutes with no help from the user. But you're going to have to pay: new systems cost $5k. I got mine used off eBay and installed it myself for $2k. Soldering Iron not required, but expect to cut and crimp a little cable, and of course you have to do the roof mounting. The hardest part was lifting the dish up onto the roof, because it's 80lbs with mount.
4) Contrary to what some other poster said, these dishes are NOT comparable size to TV dishes. They are larger, because they need to transmit info back to the bird. They start at 0.74m diameter. This means that pointing them is harder than pointing a TV dish, and they absolutely cannot be used while in motion.
5) Do not buy an RV with a rubber roof. Just don't.
6) Are you using solar power? I do, and it's worked out quite well. I could give you some tips if you want.
My recommendation would be Hughesnet with a motorized tracker, and a 3G phone if you need connection while moving on the highways. You can learn more about my experiences with the technomadic lifestyle at http://lauralan.livejournal.com/

Massive VMware Bug Shuts Systems Down 410

mattmarlowe writes "Imagine if Red Hat released a version of Linux, and after it was deployed, customers noticed that any processes with a start date of today would refuse to run? Well, that's what happened to VMware — a company that wants nearly all server applications running in virtual machines within a matter of years." Supposedly a fix will be available ... in 36 hours.

+ - Sat-nav turns drivers into 'kid killers' 2

Submitted by Stony Stevenson
Stony Stevenson (954022) writes "Satellite navigation systems "seriously undermine road safety", Dutch academics claimed today. The Stichting Onderzoek Navigatiesystemen (Navigation Systems Research Foundation) warned that software errors in sat-nav devices are preventing motorists from finding ring roads around cities. Almost none of the navigation systems tested by the organisation were found to take adequate account of hierarchies in road networks. As a result, motorists are unnecessarily being turned into "kid killers" by being sent through designated low-traffic residential areas and roads which are not designed for through-traffic."

SCO Blames Linux For Bankruptcy Filing 321

Posted by Zonk
from the comment-write-themselves dept.
Stony Stevenson writes "SCO Group CEO Darl McBride is now claiming that competition from Linux was behind the company's filing of Chapter 11 bankruptcy. 'In a court filing in support of SCO's bankruptcy petition, McBride noted that SCO's sales of Unix-based products "have been declining over the past several years." The slump, McBride said, "has been primarily attributable to significant competition from alternative operating systems, including Linux." McBride listed IBM, Red Hat, Microsoft, and Sun Microsystems as distributors of Linux or other software that is "aggressively taking market share away from Unix.""

Water vapor would be a powerful greenhouse gas, if there weren't already so much of it there. Basically, our atmosphere has so much water vapor, that every frequency of IR that can be absorbed by it is already fully absorbed. So more water vapor won't make a difference. CO2 and CH4, on the other hand, are potent greenhouse gasses because not only do they absorb IR, but they're pretty scarce our atmosphere.
