I'm sorry, but going to Mars is NOTHING like going to California. You can be pretty well assured that wherever you go on Earth, you won't die of suffocation (except maybe from exposure to fumes from an active volcano). And food grows or is found almost everywhere on the planet (excluding Antarctica -- even most deserts have food available in them).

The only way Mars would work is if machinery can be sent that digs a deep enough pit, so it can have a usable air pressure. From there it can be terraformed.

:: Why would you pick classes that wouldn't transfer?

Simple -- you have basically 3 degree options in Community college -- Associates in Arts, Science, and Applied Science. The applied degree consists of classes that generally don't transfer. However, that degree does prepare you for the work place after 2 years (assuming you can find a job that doesn't think of an Associates degree as a failed Bachelors). Whereas the non applied degrees won't give you any job skills, but only prep you for a 4-year college. In any case, it is recommended that a student work with the target 4 year institution, to determine which courses to take at the local community college, and not do it blindly.

However, this is actually a bigger issue. A lot of the high school classes are dumbed down enough that they really don't prepare students for college level courses. So often times students have to take 1 - 2 semesters of additional prep work classes before they can jump into the real college classes. This can even be true if one took "college prep" classes in high school (depending on how crappy the local school district is).

It actually depends. Back a while ago, a large consulting / outsourcing firm had faced a lawsuit, that a bunch of their IT employees were mis-classified. The outcome of that suit is that they were all reclassified as hourly, eligible for overtime -- but their pay got slashed by about 30%.

For myself, I like not having to punch a clock or fill in a time sheet. And if I have to run out an hour early, I like that my pay won't be docked by that amount. (Note, that employers can deduct hours from your vacation pool for less than either 8 hours a day worked, or 40 hours a week, can't remember which, but they can't dock your pay if you are exempt).

The way the updates work: When the device check Google for an update, for the first few days it gets a random chance of 1 in 100 of being selected. That chance is then reset after a few days, so when it checks again it gets another chance, maybe 5 in 100. Note, that once the dice is rolled, no matter how often it checks for updates, it will always get the same decision until a certain time has elapsed. This chance increases as time goes on, allowing more devices to get the updates. If there are a significant number of issues reported during the first few days, this gives Google a chance to address the issues with additional patches, or to pull the update completely if required.

Let's say you pay the burger flippers more. That means the price of the burger goes up (the money has to come from somewhere). Now, the person working at the bread factory is going to want more pay to afford the higher cost of the burger. And so is the plumber. And the construction worker building a house. All of these companies now have to raise the price of their products to accommodate the higher payroll. Looks like raising the pay of the burger flipper really didn't accomplish much, as bread and housing is now more expensive. Congratulations.

That 25 seconds of fuel was landing fuel. If they ran out before landing, they would have pushed the abort button and shot back into orbit with the takeoff fuel allocation. Now I don't know if this was automatic, or if the launch fuel physically separated (to absolutely prevent using it for landing), so that could have been a factor also.

I agree that most of what people have can be re-downloaded. However, separating that out is a chore, and what if you miss something? Might as well back up the entire drive just to make sure. But that would be a great product -- a search engine service that you can upload a list of file hashes and have it return a url for each file that is available online.

I haven't used rdiff-backup, but I used to use rsnapshot (actually a homebrew equivalent to it) -- was backing up several hosts to a central one. But I really missed having all the backup metadata in a database, where I could do simple SQL queries to find out file patterns were taking up the most space (this helps you tune your include/exclude list). Also, trying to replicate a rsnapshot volume that had a bunch of hard links (each day's backup's common files were hard linked to the previous days' files) -- this made for some very slow copying, unless I did a raw image copy (30 systems, with 10 daily, 6 weekly, and 12 monthly backup each made for a lot of file inode entries). That's why I wrote Snebu, so for each file that doesn't change between backups, only one gets stored. And references between backup sets are handled in the DB (sqlite3 based) instead of via hard links in the filesystem. Oh, and files are also compressed (lzop compatible format), which is something that rsnapshot didn't give me.

My favorite feature, that I'm testing out now (should be in the next version once it is stable and I hammer out the UI issues) is the ability to have a shadow copy of the backup DB that you stick on a thumb drive. This allows you to make incremental backups of your laptop to the shadow copy and sync it back to the main backup later on. Other features coming include external plugin modules to support moving / copying older backup sets to independent volumes, and potentially tape changers and cloud storage too (however these will all be secondary storage locations, the primary will be local storage).

Rotational Vibration (RV) is the vibration the drive experiences from the platters rotating at high speed. When you put a bunch of drives in a cage, some interesting harmonics build up which can shorten the life span of the drives further. Enterprise grade hard drives are built to better withstand these vibrations, lessening the chance of failure. (At least that is what their literature says -- personally I'd mount the drives using grommets or something like what Rackspace uses [rubber bands I think?]).
