The article on Page Attribute Tables. Doubled in size since I wrote it.. which isn't saying much.

The transaction limits on unverified payments are pretty small (£15 here in the UK, recently raised from £10), and you'd expect any such system to be wary of lots and lots of them.

The lack of signature and PIN verification also means any liability for losses through such a system rests on the bank, not you, provided you report the loss of your card in good time. Same should apply if someone manages to exploit such a feature while you still have your card, provided you dispute the payments not too long after receiving your statement.

Firefox has Firebug; a web debugger, basically -- tracing JavaScript execution, examining and poking at the DOM, CSS, etc.

Dragonfly is the same kind of thing for Opera; and indeed, potentially other browsers which support Scope Transport Protocol.

Right, and it's less likely to die from shock or head crash or manufacturing defect, and when it runs out of erase cycles it fails soft; writes fail, but it's still readable; certainly a better failure mode than most drives. Yes, the X25-M has a 5 year design life, just as platter based drives, but I suspect it's also more likely to actually achieve it, firmware update screwups aside.

The MLC X25-M is rated at 20GB/day for a 5 year service life, why would most people care?

ATI drivers work well enough for me in Win XP, Windows Vista and Windows 7, on a HD3200, 4870 and 5870 respectively.

On the other hand the nForce 4 chipset on my motherboard died and my 8800GTS 512 died, so I tend to avoid their stuff now.

Aren't anecdotes great?

I would expect they'd be using some sort of slot, something like this. Motherboard manufacturers aren't exactly going to be thrilled at the idea of putting some yet more expensive components on there, but they might be happy to hook up a small ZIF socket thing like some of them do with CF.

Intel actually had some weird ZIF connected SSD's on there a while ago on preorder, but they appear to have disappeared.

Either way, it's nice to see some hybrid storage stuff which isn't ZFS L2ARC (zpool add tank cache /dev/my_ssd -> tank now has an 80GB SSD for fs cache). Kind of surprised it hasn't been done in software elsewhere really; you'd think there would be some Linux developer who found the idea compelling, or even Microsoft wanting to extend ReadyBoost to its logical conclusion.

I've tried an X25-M on a few servers with LSI SAS controllers (as used by PERC 6i, though I don't think I've used that exact chip) and been disappointed to encounter IO hangs and other drives disappearing randomly; even just having an X25-M plugged in is enough to seemingly make the controller rather unhappy. Doesn't appear to be a driver problem, unless it's one shared by FreeBSD, Linux and Solaris.

Hopefully Intel will do an SAS version at some point; they could compete against 15kRPM drives rather well, I think.

Intel rated the first generation X25-M's at 100GB/day for 5 years, I'd be surprised if these were significantly worse.

In my tests, gcc only optimizes out null checks at -O3 or above, which is already known to make potentially unsafe optimizations. Maybe if -Wunreachable-code were part of -Wall it would have been easier to spot.
