Everything beyond had cycle counts for the best possible case, i.e. everything cached. 16:11:10 Seems to be several Hundreds of that Message per Second 16:12:08 Basically what happens is that timings for accesses outside the first level cache are unspecified, but people figure out how to extract information from those unspecified timings. That's been going on for several years already, but meltdown/spectre have made it very clear that this isn't just of theoretical interest. 16:13:58 that general sort of issue has been around for ages 16:14:05 this is more interesting, especially spectre variant 2 16:14:18 which basically runs arbitrary code in the speculator via chaining together gadgets using hash collisions in the branch predictor 16:14:55 Yeah I know. 16:15:14 But it's still a timing sidechannel at its core. 16:15:48 the timing sidechannel is basically just used to get output from the code as it can't output the usual way 16:15:54 I'm not even sure it's the only such sidechannel 16:16:29 "The Speculator" sounds like a superhero/villain name. 16:19:16 Jan 5 16:59:39 Zarniwoop kernel: [ 173.713097] nouveau 0000:01:00.0: fifo: SCHED_ERROR 0a [CTXSW_TIMEOUT] 16:19:19 Jan 5 16:59:39 Zarniwoop kernel: [ 173.713106] nouveau 0000:01:00.0: fifo: gr engine fault on channel 5, recovering... 16:19:23 Jan 5 16:59:39 Zarniwoop kernel: [ 173.713852] nouveau 0000:01:00.0: fifo: INTR 00800000 16:19:26 Jan 5 16:59:39 Zarniwoop kernel: [ 173.714007] nouveau 0000:01:00.0: fifo: INTR 00010000: 00000002 16:19:29 Then it goes on spamming the last Message endlessly 16:20:02 looks like the code was too complex for the GPU but there's a bug in the codepath that would recover from that 16:20:22 Mh 16:20:33 ais523: I'm under the impression that it is the only one that purely depends on the CPU. Hardware that snoops busses may see interesting stuff as well. 16:21:32 performance counters, perhaps? 16:21:51 hmm. maybe 16:24:45 (and they do share the property of being woefully underspecified) 16:24:56 random link http://www.gwern.net/Turing-complete 16:25:53 I can also see the possibility of tying up an execution unit and then determining the fact that that's happened by seeing how a race condition resolves 16:26:08 which is not technically the same thing as timing 16:28:25 ais523: right. you can sort of do timing by quickly increasing a counter in memory from one cpu thread and reading it from another cpu thread. not very reliable unless hyperthreading is enabled and you choose two cpu threads that share their L1 cache, but still works. 16:28:46 that's abusing multi-thread memory access nondeterminism 16:29:55 and there are other cpu-dependent ways to detect if something is in some level of cache, without timing or race conditions, like when some instruction sets have an instruction to throw away a cache line without writing it back to the slower cache or ram 16:30:45 b_jonas: oh, clever 16:30:52 maybe you could do something similar with self-modifying code 16:31:25 ais523: hmm... that would be harder in practice IMO 16:33:59 ais523: you could also abuse the x86 transactional memory instructions, which make some internal details observable (though generally you're supposed to write code in a way that those details cancel out in the end) 16:34:12 obviously that only works on new enough cpus that have them 16:34:42 and yes, performance counters are obviously the easiest way 16:34:54 intel cpus have a rich set of them 16:37:15 but generally only the people who work on optimizing low-level stuff use them 16:57:00 -!- GautamS_ has joined. 17:01:15 -!- GautamS has quit (Ping timeout: 260 seconds). 17:18:15 -!- GautamS_ has quit (Quit: Leaving). 17:23:22 -!- oerjan has joined. 17:34:38 -!- Guest58342 has changed nick to Slereah. 17:41:12 [[Numberwang/Implementations]] https://esolangs.org/w/index.php?diff=53750&oldid=53749 * Unt * (-3) The interpolation algorithm was incorrect.

ZZZzzz…). 22:03:03 Do some computer programs that use punch cards to allow later columns of the card to override earlier columns in order that you can alter the data without needing a fresh card until it is full? 22:04:41 flash card technology 22:05:18 zzo38: they normally use a different method: if you punch every hole in a column then the column is treated as not existing, then you can put more data on the rest of the card to override it 22:07:31 Ah, OK. (Still, some programs may require specific columns to be used, in which case that doesn't help so much) 22:08:21 this is why ASCII has a DEL character with code 127 22:08:22 (And MIX does not even have the mechanism you mentioned) 22:08:40 ais523: Yes, I have read before, that is why ASCII has that. (Still, punch cards don't normally use ASCII, though) 22:08:51 right, ASCII was more for tape than card 22:11:29 Yes, OK 22:13:04 The calendar program I write for MIX, allows you to override the year number (and only the year number) by punching additional holes into more columns; you do not need to repunch the entire columns previously used for the year (which may damage the structure of the cards maybe; but even if it doesn't, the computer is not necessarily compatible with punching an entire column, since MIX doesn't require that to work) 22:16:14 Actually you can do this for the text as well, just due to how it is working; later text on the same line of the same day will override previous texts, so it does do that too (without any special logic to deal with this). 22:32:12 -!- `^_^v has quit (Quit: This computer has gone to sleep). 22:35:37 -!- MrBismuth has joined. 22:39:08 -!- MrBusiness has quit (Ping timeout: 265 seconds). 22:41:47 -!- moony has joined. 22:52:01 -!- boily has joined. 22:52:07 @metar CYUL 22:52:08 CYUL 052200Z 26020G30KT 1 3/4SM -SN BLSN BKN018 OVC030 M20/M24 A2969 RMK SF5SC3 SLP058 22:52:16 BLSN everywhere. 22:54:08 ?metar CYVR 22:54:08 CYVR 052239Z 08007KT 7SM -RA FEW008 SCT014 BKN018 OVC025 08/08 A2993 RMK SC1SC2SC4SC1 SLP138 22:54:43 Please tell me if you think anything important I may have missed in my printer protocol document 22:55:13 hezzo38. probably nothing? 22:55:40 Did you read it? 22:56:40 <_<'... >_>;... 22:59:34 Do you know if Microsoft Word will pay attention to page-break CSS properties when importing a HTML file? 23:08:17 The protocol I made up is a simple protocol, which could be used in many places including at a hotel to allow people who stay at a hotel to print from their computer on the hotel's internal network.
