| 15:35.28 | LunaVorax | Hello everyone! |
| 16:14.14 | larsc | Ayla: sort of. if there is no other active part, it will shutdown the whole analog output domain |
| 16:14.29 | larsc | and also the dac itself |
| 16:14.42 | larsc | DAPM uses a graph |
| 16:15.39 | Ayla | well, if I understood correctly, several steps are needed to power on/off the DAC without creating noises |
| 16:17.10 | kristianpaul | viric: lol |
| 16:19.48 | DocScrutinizer | Ayla: good point :) |

| 16:20.52 | DocScrutinizer | I'm generally no friend of too much "AI" in kernel(-drivers) |
| 16:21.44 | DocScrutinizer | esp when there's no way to override or even just check what that AI is doing |
| 16:24.09 | DocScrutinizer | first and foremost a driver shall export hw functions completely and in a basically unfiltered way. Then on top of that it *may* implement some *optional* "intelligence" |
| 16:28.29 | DocScrutinizer | you could argue if a driver should allow to even write invalid values to registers or rather limit acceptable values to the range that's defined by the chip's/circuit's specs |
| 16:30.13 | DocScrutinizer | for some drivers like e.g. lp5523 you'd think they better had limited /sys/class/leds/lp5523:kb3/led_current to values that won't fry your LED |
| 16:31.25 | DocScrutinizer | for other drivers (e.g. FMTX) you'd think it would be nice to test what results you get when writing values higher then the "allowed" 120d to tx_power |

| 16:33.30 | DocScrutinizer | my take on that usually is "get a module parameter 'sanity-check=disable' to pass to the driver on modprobing it" |
| 16:34.35 | DocScrutinizer | but definitely I think a driver that doesn't even expose *any* way to fiddle with e.g. audio codec function block suspend, that's broken by design |

| 17:25.32 | viric | wpwrak, kristianpaul: YPF, argentina! :) |
| 17:26.45 | viric | congratulations. |
| 17:36.34 | viric | I can't tell much for the argentinian part, but repsol is not my list of friends. |
| 17:36.51 | viric | But it may be all circus, as usual. |
| 17:39.53 | wpwrak | viric: you're congratulating argentina for being de facto blocked from equitable investment for at least the next three years, after setting this sort of precedent ? :) |
| 17:44.46 | viric | wpwrak: among other things, yes ;) |
| 17:44.53 | viric | but things are not so simple. |
| 17:45.54 | viric | wpwrak: today one of those in the Spanish government said: "Ya no estamos en campaña; es momento de decir lo que de verdad pensamos" |
| 17:46.18 | viric | (unrelated to ypf :) |
| 18:01.51 | wpwrak | viric: well, if you google for moreno or boudou, you should be able to get a fairly quick impression of how politics are going here these days |
| 18:03.05 | wpwrak | viric: i appreciate your schadenfreude at your government receiving a blow below the belt, but i think this may just be a case of everyone ending up on the losing side |
| 18:03.21 | viric | it can be, it's hard to know in advance. |
| 18:03.33 | viric | It's some kind of elite against some other kind of elite |
| 18:03.43 | viric | (or same kind, but different people at least :) |
| 18:04.21 | wpwrak | (know in advance) right. if you jump out of a 10th floor window, you can't be sure in advance what exactly will happen :) |
| 18:04.34 | viric | ah well, you seem quite sure :) |
| 18:05.10 | wpwrak | when you see patterns repeat for the third of fourth time, you begin to have a hunch :) |
| 18:06.02 | wpwrak | only a year ago, the same president was praising ypf for their great investments in argentina |
| 18:06.22 | viric | I've no idea on the argentinian government. As for the Repsol side... do you think it has been a trick, and the old owners have received benefit of this operation? |
| 18:06.48 | wpwrak | now, in the middle of a major crisis involving the vicepresident, all of a sudden they pop out that "patriotic" card. malvinas, anyone ? :) |
| 18:07.15 | wpwrak | there will probably be endless lawsuits following this coup |
| 18:07.27 | wpwrak | much like after the "haircut" in 2002 |
| 18:08.26 | wpwrak | some of the 2002 lawsuits are still going on. and present a danger for argentine assets abroad. as soon as someone can plausibly show that they're under the control of the government, they can be sized. that has happened already. |
| 18:09.10 | viric | wpwrak: do I read right that the nationalisation has been realized by Dromi, who prepared the former privatization (of YPF)? |
| 18:09.11 | wpwrak | so the YPF coup may also have some unintended consequences |
| 18:10.33 | viric | If someone is psichopatic, egoist, greedy, and corrupt, that has lots of chances to participate with great power in a country government ;) |
| 18:11.18 | viric | wpwrak: I hope the spaniards don't decide to go into some kind of 'war'... as in the Perejil case |
| 18:14.32 | viric | https://es.wikipedia.org/wiki/Incidente_de_la_isla_de_Perejil I hope we can see "Perejil: the movie" some day |
| 18:20.05 | wpwrak | dromi ? haven't even heard that name. i think on the argentina side, kicillof had a lot to do with it. a rather dubious character. |
| 18:20.22 | viric | Roberto Dromi |
| 18:20.49 | wpwrak | argentina has almost no military force these days. which is good. keeps the government at least from that sort of folly |
| 18:21.44 | viric | Here they don't know whom to give more money: military or church |
| 18:22.15 | wpwrak | for spain, it may be attractive, though. kill off a few angry young man. maybe they could put them on board of decrepit ships, sink them, and then blame argentine submarines :) |
| 18:22.27 | wpwrak | a good investment in either case :) |
| 18:22.33 | viric | wpwrak: if you google from roberto dromi, you see him both in the privatization and in the nationalisation :) |
| 18:22.43 | viric | wpwrak: could be :) |
| 18:22.56 | viric | wpwrak: google for. |

| 18:25.20 | wpwrak | i only see him mentioned on the side of privatizations |
| 18:25.48 | viric | http://www.bnamericas.com/news/electricpower/Repsol_Plans_YPF_Share_Acquisition3 |
| 18:26.31 | viric | wpwrak: when I said "google", in fact I was using ddg :) |
| 18:27.56 | wpwrak | in that deal, he was quite on the privatization side |
| 18:28.41 | wpwrak | i don't see any mention on him pushing nationalization anywhere |
| 18:28.59 | wpwrak | of course, some things were nationalized. but that wasn't his doing |

| 20:43.27 | viric | hahaha |
| 20:50.55 | wpwrak | i think argentina will now retaliate by excluding columbian students from some scholarship programs |
| 20:52.21 | wpwrak | at least that's what i gather may be behind an odd "interview" that popped up in some approval process a brazilian friend is presently going through |
| 20:55.21 | wpwrak | the timing isn't entirely right, though. that thing came up a few days before the summit. maybe it's in response to police reports indicating that some 80-90% of burglaries are committed by columbian gangs that send "students" to act as beach heads (so they have all their papers in order an can rent an apartment. then the rest of the gang follows without having to bother with bureaucratic niceties) |
| 20:56.08 | viric | what a complot |
| 20:56.41 | wpwrak | yeha. maybe it's just the ritualized feeding of xenophobia :) |
| 21:04.20 | viric | Do you think this may work? |
| 21:04.29 | viric | http://www.repuestosfuentes.es/product.php?id_product=194 |
| 21:04.34 | viric | sounds very cheap |
| 21:04.40 | kristianpaul | wpwrak: ;) |
| 21:04.45 | viric | looks like wanting only usbhost |
| 21:04.55 | kristianpaul | now i will not travel to argetina and visit wpwrak :D |
| 21:06.20 | viric | I don't know if there are limits on unidirectional transmission power. |
| 21:07.09 | viric | *legal* limits |
| 21:07.23 | viric | it's not that I want to play being Tesla |
| 21:08.29 | wpwrak | it doesn't really say what TX power it has, does it ? |
| 21:08.41 | kristianpaul | or RX gain limit? ;-) |
| 21:08.47 | wpwrak | kristianpaul: afraid or insulted ? :) |
| 21:08.52 | viric | 60dBi |
| 21:09.05 | viric | I don't know that unit though. |
| 21:09.06 | wpwrak | naw, you can make your RX gain as high as you wish |
| 21:09.41 | kristianpaul | wpwrak: neither :) |
| 21:09.44 | wpwrak | viric: that's the amplification. but what's the input ? |
| 21:09.56 | viric | hm no |
| 21:10.08 | viric | dbi is the relationship between directional power / omnidirectional power |
| 21:10.24 | viric | (just checked) |
| 21:10.39 | kristianpaul | wpwrak: may be afraid of ticket costs ... |
| 21:10.40 | kristianpaul | he |
| 21:10.54 | viric | it may be the usual 15 or 20dBm |
| 21:12.41 | wpwrak | viric: (dBi) provided they got that right :) 60 dB of anything seem suspicious, though |
| 21:13.20 | wpwrak | if it's really dBi, that would be a rather narrowly focused directional antenna |
| 21:13.59 | wpwrak | maybe it's just dBM, with M = Marketing |
| 21:15.30 | viric | haha |
| 21:15.37 | viric | yes, it sounds very narrow. |
| 21:17.48 | viric | I've really have zero experience with unidirectional antennas |
| 21:23.40 | wpwrak | if i understand the concept right, the beam width would have to be around 22 arcseconds for that. still not as good as a decent laser, but close |
| 21:23.50 | viric | :) |
| 21:23.58 | wpwrak | well, the beam divergence, to be precise |
| 21:24.02 | viric | I decided not to engage into such a calculation... |
| 21:24.12 | viric | 22 arcseconds is quite narrow ;) |
| 21:24.34 | viric | laser at radio freqüency; nice! |
| 21:24.53 | wpwrak | you could mount a laser on the antenna to indicate where to place the opposite antenna ... |
| 21:26.42 | viric | fair :) |
| 21:31.21 | whitequark | I heard that the main reason such laser-antennas aren't produced is because of their marginal usefulness |
| 21:31.43 | whitequark | due to them being very hard to position |
| 21:34.06 | viric | of lasers at visible spectrum you mean? |
| 21:34.34 | viric | I remember seeing them for high speed links between buildings |
| 21:34.39 | whitequark | nope, by "laser-antenna" I meant an RF antenna with a very narrow link |
| 21:34.48 | viric | ok |
| 21:35.13 | viric | as visible spectrum today I saw this http://www.interconnect-ns.co.uk/Laser-Links |
| 21:35.49 | whitequark | haha, nice. my classmate once did a simple version of that |
| 21:36.10 | whitequark | with a typical chinese laser pointer (it was before those EXTRA BRIGHT green lasers and stuff) |
| 21:36.16 | viric | well, I claim it's for visible spectrum, but it does not say that. |
| 21:36.27 | whitequark | well it's possible |
| 21:36.34 | whitequark | even with a chinese pointer, that is |
| 21:36.46 | wpwrak | whitequark: they may also be a bit inconvenient to carry around. e.g., the arecibo dish seems to have 60 dBi ... |
| 21:36.46 | whitequark | of course he only got 120 baud or such, but hey, that was a one-weekend project |
| 21:36.54 | viric | good enough |
| 21:36.54 | whitequark | wpwrak: :-) |
| 21:37.06 | viric | haha |
| 21:37.37 | viric | wpwrak: for high enough frequencies, maybe it can fit your pocket. |
| 21:37.56 | whitequark | I sometimes wonder about THz spectrum |
| 21:38.08 | whitequark | that is, the visible part of THz spectrum |
| 21:38.21 | whitequark | it's still "radio" waves, right? it's electromagnetic radiation |
| 21:38.29 | whitequark | so, can we use metal antennas to emit it? |
| 21:38.39 | whitequark | just imagine an antenna which glows when turned on |
| 21:39.23 | viric | yes I wondered about that too |
| 21:42.21 | whitequark | it's like LEDs, but other way around |
| 21:42.42 | whitequark | we can generate light by shifting electrons back and forth between the orbitals in a LED |
| 21:42.55 | whitequark | and we can generate radio waves by doing the same, for example, with hydrogen |
| 21:43.01 | whitequark | the freq would be something like 2MHz |
| 21:43.06 | whitequark | or 20, I don't quite recall |
| 21:45.20 | whitequark | through the antennae for THz waves should be quite small |
| 21:46.38 | viric | I can't tell if you understad all this better or worse than me |
| 21:47.13 | whitequark | and after a certain wavelength (gamma? xrays?) you'll need to make them smaller than atoms |
| 21:47.19 | whitequark | hmm |
| 21:47.53 | whitequark | on the other hand, what an antenna is? a structure where a wave can propagate well because of lots of free electrons |
| 21:48.59 | whitequark | that is, when we talk about antennae and waves, we don't treat quantums or their relations as separate particles |
| 21:49.07 | whitequark | so in a certain sense a single atom can be an antenna |
| 21:49.24 | whitequark | no idea if I'm telling nonsense or not :) |
