00:41:47 <int-e> Ah, there goes the predictable VM reboot.
01:03:27 <oerjan> so, i assume today's xkcd is pretty much right that we're doomed.
01:05:24 <zzo38> That is the problem with these design they design the computer too much complicated
01:06:21 <ais523> that analogy isn't quite right, but it's a good one
01:06:50 <ais523> it's more like the phantom trolley only goes one way, but you can direct where it goes by flapping butterflies at it
01:09:17 <zzo38> Can't you make simpler computer designs that do not have these problems?
01:10:35 <ais523> zzo38: yes but they don't run very fast
01:10:51 <ais523> although rowhammer is not really a problem of simplicity but size
01:11:09 <ais523> in fact it's normally fixed by making the memory more complex, to detect rowhammered bits and put them back to normal
01:12:16 <zzo38> Does SRAM have that problem too?
01:13:12 <ais523> I think so, it might be more resistant to it though because the voltage levels for the bits are further apart
01:13:33 -!- wob_jonas has joined.
01:14:51 <wob_jonas> zzo38: I dunno, but I think the problem with SRAM is that if you want a lot of it (like for gigabyte sized main rams) then it needs a ten times bigger chip than DRAM. so SRAM is used only for smaller pieces of memory.

01:16:50 <zzo38> Well, I still think it is going to be simpler than DRAM, it look like, to me.
01:17:10 <zzo38> (Since DRAM require refresh timings and so on, and if it is not the same as the instruction timing then it won't work.)
01:18:46 <wob_jonas> Just imagine needing a ten times bigger RAM card than your PC has now.
