Comment Re:Get the word out: SLC vs MLC (Score 1) 160

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.

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.

In Dwarf Fortress, at least, you have to memorize an arcane system of key commands to navigate through a literal fortress of menus

The standard display lists those key commands in the side of the window. You likely will memorize at least some of them during use, but you certainly don't have to.

An 80x50 window with 16x16 tiles takes up a quarter of my display. I normally run much bigger than that, and the tiles look pretty distinguishable to me - certainly more so than just using colours to distinguish goat from goblin and peasant from hammerdwarf.

If I need a bigger overview, d12 supports zooming; it's still usable at 8x8, but I rarely find myself wishing the standard display was that small.

Dwarf Fortress is fucking retarded. A text based game that requires Windows or OSX, 512 MB of RAM, and an OpenGL video card. No Linux and no mobile device support

Linux version. And it works fine on my laptop, great way to wile away a 4 hour train journey.

What's the point?

Um, it's a fun game? What other point do you want?

Using what encoding scheme? With a single mark the best I can think of is to treat it as a variable-length base 1 value; increment a Bignum for each atom until you hit the mark, and the final binary encoding of that is the data.

A 10TB LoC would make up a Bignum 87960930222080 bits long (and thus with a range of 0 - 2^87960930222080 - 1). Sadly with this encoding scheme the universe only contains enough atoms (~10^80) to encode about 32 bytes of that.
