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.

The Challenges and Threats of Automated Lip Reading 120

An anonymous reader writes: Speech recognition has gotten pretty good over the past several years. it's reliable enough to be ubiquitous in our mobile devices. But now we have an interesting, related dilemma: should we develop algorithms that can lip read? It's a more challenging problem, to be sure. Sounds can be translated directly into words, but deriving meaning out of the movement of a person's face is much more complex. "During speech, the mouth forms between 10 and 14 different shapes, known as visemes. By contrast, speech contains around 50 individual sounds known as phonemes. So a single viseme can represent several different phonemes. And therein lies the problem. A sequence of visemes cannot usually be associated with a unique word or sequence of words. Instead, a sequence of visemes can have several different solutions." Beyond the computational aspect, we also need to decide, as a society, if this is a technology that should exist. The privacy implications extend beyond that of simple voice recognition.

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?]).

RHEL 7 Beta is based off Fedora 19, with a 3.10 kernel. Usually their beta cycles run about 6 months. Oh, and they heavily backport to their stable kernel (it is "stable", not meaning crashes less, but referring too the fact that the API/ABI doesn't change when they release updates).

Other than the not having to work part, we really do live like kings. We get to sit in a seat to be transported from place to place, our homes are heated and cooled, running hot water, plumbing, non-rancid food, quite a bit of food actually, we can pull up music and other entertainment on demand, and have great libraries at our disposal. The list goes on -- most royalty a couple centuries back didn't have it this good.
