It is possible, but for good performance it needs hardware support. We've implemented hardware-enforced bounds checking for C code using our processor. If you only care about accidental bugs and not about a malicious attacker, and don't use threads (or are happy to bound every pointer store with a transactional region), and don't mind that the semantics of C are subtly broken in the kinds of permitted pointer operations, then Intel's Memory Protection Extensions will do the same thing.

The OpenBSD philosophy says that the difference between a bug and a vulnerability is the intelligence of the attacker. There are lots of categories of bugs (null pointer dereferences, integer overflows) that were thought to be unexploitable, right up until someone exploited them. It's the same as with cryptosystems: the fact that you can't break your encryption algorithm doesn't mean that it's secure.

Your laptop has to be on the same network as your backup machine, but even backing up my laptop over WiFi only takes a couple hours for an incremental backup. I don't have to leave it doing nothing, I just need to leave it on. If I haven't backed up for a while, I might leave it doing the backup overnight, but most of the time I run the backup while I'm working.

I bought 3 2TB disks just before the flood. About a month ago, they finally became cheaper than I paid. I'd been planning on swapping them out for 4TB disks after 2-3 years, but the 4TB ones are still 50% more than I paid for the 2TB disks. At this rate, 4TB flash will hit the £50 mark before 4TB hard disks...

The difference in cost between tapes and disks hasn't changed much, but the difference in cost of the tape drives to disk drives has changed hugely. You used to be able to get a tape and a drive for only a little bit more than the cost of the disk it would back up. It made sense to use tapes for backups then, because you could afford one tape for the same cost as a backup disk and add new tapes for very little money. Now, if you buy a disk at the sweet spot for price, the tape drive that can back it up to a single tape will cost you about an order of magnitude more than the disk drive. At that point, unless you want a lot more than 10 backups per disk, it isn't worth it.

That's not necessarily true. You can get the same amount of space in a smaller number of tracks around the edge of the disk, so the horizontal movement for the largest seek is going to be smaller. Seek times on mechanical disks are based on three factors. The first two are related: the time it takes to move the head between tracks (proportional to its distance) and the time it takes for the head to settle and be able to be lowered again (dependent on its speed). The third is the time it takes for the correct sector on the track to spin under the head. In the middle, you have fewer sectors per track, so you need to move the head more often (this is where the upper bound on seek times comes from).

And that's why, if you can, you go back to college to get a Bachelor or Masters degree when you get into your late 30's early 40's.

That is the worst possible advice you could possibly give, except I guess for killing yourself.

That is when instead of SPENDING ALL YOUR SAVINGS ON SOMETHING THAT WILL NOT MATTER, you should instead think about switching to consulting and increasing your earnings. Can't find a full-job easily past 40-50? Learn to make people pay what you are really worth for the vast amounts of experience you have, because that is worth a lot, save up what you can and enjoy retirement eventually, possibly a lot earlier than you would have if you burned your money like an idiot getting a business degree so you could be unemployed with all the younger business majors who cannot find jobs either.

When did hard drives not fail? I've had failures since the early 90s, when they were in the 200 MB range.

Well, I'm sure someone will speak up about some tales of DASDs of yore still older than what I've had, but I still remember when Seagate was called "Seizegate" because of the frequency of occasion when one needed to dismount the drive, place it upon a soft surface, and give it a good rap on one corner (perpendicular to the axis of rotation) in order to permit it to spin up. 21MB of ST-225, baby.

They just lifted them into place. The big ones might have taken two to four people. If you hadn't noticed that each generation has gotten weaker, lazier, and more morally depraved than the last, ask your parents and/or grandparents -- reserve the afternoon. Thus, by extension, back in ancient times, people had strength, stamina, and willpower that we attribute only to supernatural beings today.

this would be a disaster for America, and CONcast.

Why is it no surprise we are suppose to live in a "free country", " free market" and yet our politicians are pretty much hand puppets just shove your money up their ass and make them dance. And people keep voting for this baboons, and allowing industries and corporations to pretty much OWN them.

I think the only hope we have right now is if enough yuppies get together and actually do something Gaagle has failed at, create another ISP service that is free, open, fast, and cheap.

By "Gaagle" do you mean Google if so what do you mean they have failed they are still expanding and delivering g.b.p.s. internet speeds and prices from other providers they are competing with have dropped where google has gone in and their speeds have gone up to match.
