BTRFS and ZFS both do checksumming and can detect bit-rot. If you create a RAID array with them (using their native RAID capabilities) they can automatically correct it too. Using rsync and unison I once found a file with a nice track of modified bytes in it -- spinning rust makes a great cosmic ray or nuclear recoil detector. Or maybe the cosmic ray hit the RAM and it got written to disk. So, use ECC RAM.

But "bit-rot" occurs far less frequently than this: I find is that on a semi-regular basis my entire filesystem gets trashed (about once every year or three). This happened to me just last week...my RAID1 BTRFS partitions (both of them) got trashed because one of my memory modules went bad. In the past I've had power supplies go bad causing this, or brown outs, and in other cases I never identified the cause. I've seen this happen across ext3, jfs, xfs, and btrfs so it's (probably) not the file system's fault. In such cases, fsck will often make the problem worse. (Use LVM and its "snapshot" feature to perform fsck on a snapshot without destroying the original). You'd think these advanced filesystems would have a way to rewind to a working copy (for instance in BTRFS -- mount a previous "generation") but this seems to not be the case.

Anyway, btrfs guys, your recovery tools could be a lot better. The COW enables some pretty fancy recovery techniques that you guys don't seem to be doing yet. If you've got a great btrfs or zfs recovery technique, please reply and tell us.

Brilliant. Every time I've been forced to not pick up poop, it was because I didn't have a bag, not because I wanted to (and where possible I always go back and get it later). I've had my dog shit three times on one walk. I'm really tired of hearing "solutions" to problems created by psychopaths. This "solution" using poop and DNA utterly lacks empathy towards dog owners, and that's what psychopaths do. There are better ways.

You've obviously never owned a dog. Sometimes your dog shits twice and you only have one bag. Sometimes you're rushing to work. Sometimes you can't find the shit.

Don't be a dick. This (and your) response is that of a psychopath.

Because a dick measuring contest is the best way to resolve disputes. Everyone is being a dick here. Take the high road, don't be a dick.

Wow, what a wonderful way to improve the already adversarial relationship between property managers and tenants. No thanks, I'll live elsewhere. If it were my building, I'd quietly have maintenance clean up any poop they found, and verbally remind tenants if they catch them in the act.

It will not take "a generation" to make the shift. It will take a systematic change in the hiring and funding priorities of universities, labs, and grant agencies. A faculty candidate who has chosen to publish only in open access journals (with no articles in Science or Nature or other "prestigious" journals) needs to be able to win the job over another candidate with publications in "prestigious" journals. Likewise, a researcher must be able to win a grant over other researchers under the same circumstances.

Currently, choosing to publish in open-access journals is arguably career suicide.

Patent enforcement should be purely economic. How much money did the infringing party make off using the patent, how much did the patent holder invest to create the patent, and therefore how much do they owe to the patent holder? Restitution should consist entirely of monetary awards.

The patent holder is often not the most capable or appropriate entity to utilize the patent. Enforcing bans like this is anti-competitive and doesn't help anyone. The patent holder would be better off receiving money from a more competent implementation of its patent, than banning all competitors and forcing everyone to use their incompetent device.

The solution to low-frequency brute force attempts is Denyhosts. It just blocks any host with repeated failed login attempts. I've been using it for longer than I can remember, probably longer than this "Hail Mary" botnet has been in existence. I'm not sure why this author seems to have never heard of it.

A first post by an AC that's actually useful. That's a FIRST.

"More" as in "I have more data on it"? Or "More" as in "I use that storage medium more often"? Nowadays, most people use SSDs more often than spinning disks, on their tablets/smartphones; but they're more likely to have much more data on spinning media.

Not to be a stick in the mud...but how is this better than the more commonly available CMOS cameras on all our cell phones? It doesn't seem to have the resolution to identify spectral transition lines (and thereby identify chemical compounds). Could you combine it with a laser or two to identify specific compounds? Since air is transparent in 400nm-700nm, it can't tell you the atmosphere is breathable...unless you ionized it first and made it glow.

What would you use this for?

From the same time frame, the encore (B&N Nook Color) is 100% supported on CM10.2 (or Android JellyBean 4.3):

That is your problem right there. Kubuntu is a terrible KDE distribution, possibly the worst out there. You'd get better performance, memory usage, features and stability from any other KDE distro.
