#qi-hardware IRC log for Wednesday, 2014-09-17

sb0_DocScrutinizer05, for you: https://bugs.freedesktop.org/show_bug.cgi?id=65575#c803:09
DocScrutinizer05sb0_: thanks, awesome04:08
whitequarkDocScrutinizer05: remember our discussion like two years ago?10:39
whitequarkhttp://m.smh.com.au/business/risky-business-china-dumps-our-dirty-coal-20140916-3fvpf.html10:39
whitequarkthough that could as well be just a minor stunt. I dunno10:40
qi-bot[commit] Maarten ter Huurne: Removed unused include (master) http://qi-hw.com/p/gmenu2x/e7248ae11:10
sunghave any of you seen any relatively pcb/hw design docs with rt5350f ?12:10
qi-bot[commit] Maarten ter Huurne: Fixed code that removes comma at end of extensions list (master) http://qi-hw.com/p/gmenu2x/499743812:45
qi-bot[commit] Maarten ter Huurne: Rewrote empty line stripping in manual display (master) http://qi-hw.com/p/gmenu2x/a03f89512:45
DocScrutinizer05whitequark: china is kinda like russia, you never know what they're actually planning and what will become of any new regulation13:25
whitequarkDocScrutinizer05: yeah, and such change isn't happening overnight13:25
whitequarkwe'll see.13:25
DocScrutinizer05tbh I'm happy when aussie coal export stalls13:26
DocScrutinizer05it's irrelevant where the coal gets burnt and transformed into pollution13:27
viricthe plan is always the same, conquest of the world13:28
viricwell, not the plan. the goal. :)13:29
DocScrutinizer05and even when china simply switches from aussie coal to local coal, they might at least extinguish their massive coal mine fires then13:29
whitequarkI think we don't really have any method for doing that? like at all13:29
DocScrutinizer05well, there are a few methoods, but expensive13:30
DocScrutinizer05what's not working is water13:30
DocScrutinizer05CO2 might13:30
DocScrutinizer05trenches work for sure13:30
whitequarkhm, it depends on what exactly burns. I think some of those fires have an internal source of oxygen?13:31
DocScrutinizer05but obviously are extremely expensive to dig13:31
whitequarklike nitrate ores or something13:31
whitequarkwhich is why they burn in the first place, being deep as hell13:31
DocScrutinizer05I don't think so13:31
DocScrutinizer05I guess the source is water and air nevertheless13:31
whitequarkhmm13:32
DocScrutinizer05it's quite unlikely that they have blackpowder in their mines ;-D13:32
DocScrutinizer05(mixture of coal and nitrate)13:33
whitequarkhaha right13:33
jbenedet1ocoal mine fires?13:33
jbenedet1ohehhhhh13:33
Action: jbenedet1o lives in Pennsylvania13:33
jbenedet1oHome to one of the most famous US mine fires: http://en.wikipedia.org/wiki/Centralia,_Pennsylvania13:34
jbenedet1omine fires are really freaking hard to put out.13:34
whitequarkyupp13:34
DocScrutinizer05>>burning beneath the borough since 1962<< wow13:34
DocScrutinizer05hey!! when you can't put it out, why not *use* it?13:35
DocScrutinizer05isn't it completely irrelevant *where* the coal burns, when you want to burn it anyway?13:36
whitequarkbtw: https://i.imgur.com/mkAgvhN.jpg13:36
DocScrutinizer05looks to me like an ideal location for "geothermic" power ;-)13:37
DocScrutinizer05congrats13:38
whitequarkno stinky touchscreen, too13:39
wpwrakwhitequark: now, among the local audience, you probably now have the best-equipped home :)13:41
DocScrutinizer05got me the tiny brother ;-)  http://www.hps140.com/13:41
DocScrutinizer05why did I read "sticky"?13:43
wpwrakDocScrutinizer05: first they become sticky, after a while stinky ... :)13:43
whitequark10MHz bandwidth13:44
whitequarkthat's ... sorta pathetic13:44
DocScrutinizer05good enough to detect some constant 147kHz noise on my desk already13:44
whitequarkwell I suppose it's good for what it's intended13:44
wpwrakgiven 40 MSa/s, that's more than enough :)13:44
DocScrutinizer05of course it's no real scope13:45
DocScrutinizer05rather sort of a graphical DMM13:45
DocScrutinizer05actually the latter is what I intended to get, but they had none13:46
DocScrutinizer05what sucks: it has no interface for data#13:46
jbenedet1oheh13:46
DocScrutinizer05that's *really* pathetic13:47
jbenedet1oas far as extinguising a mine fire, we did that recently in Pittsburgh.13:47
DocScrutinizer05how?13:47
jbenedet1oby extinguish we mean "find out which way its spreading and box it in by digging massive trenches and filling them with clay"13:47
DocScrutinizer05(data) prolly would conflict with the (rather non-trustworthy) CAT2 it claims13:47
jbenedet1oand then let it burn out.13:48
DocScrutinizer05hah! trenches13:48
DocScrutinizer05what I suggested above13:48
jbenedet1oit works but its really a huge pain13:48
jbenedet1owe are lucky the fire in question was a shallow mine.13:48
DocScrutinizer05sure, and risk of starting new fires by digging the trench ;-P13:49
jbenedet1owe have a number of deep mine fires that are as you might say, out of site out of mine. *rimshot*13:49
DocScrutinizer05that coal crap is self igniting13:49
jbenedet1owell can be. generally it gets lit by user error13:49
DocScrutinizer05nah, usually gets lit by water and air13:50
jbenedet1oCentralia's fire started as they used an open mine pit as a town dump, and when it filled up they burned it.13:50
DocScrutinizer05LOL13:50
jbenedet1o(I'm not joking)13:50
DocScrutinizer05begging for trouble is a bad habit13:50
jbenedet1oa number of abandoned mines got turned into town dumps and a number caught fire that way.13:51
DocScrutinizer05idiots13:51
viriccoal, water and air was a usual way to get light in homes13:51
DocScrutinizer05surefire literally13:51
viricplus a spark13:52
Action: DocScrutinizer05 idly wonders how many coal heaps will get ignited by rain getting heavier with global warming13:53
DocScrutinizer05you see one such heap next to each coal power plant13:53
viricwell, if you don't mine it, rain/air won't reach it13:53
viricah heaps, ok13:53
viricwell, it takes a special kind of coal to light with water13:54
viricisn't it?13:54
DocScrutinizer05brown coal won't ignite aiui, yes13:54
DocScrutinizer05not sure though13:55
jbenedet1ono clue.13:55
viricwell, for home lighting, you had to buy a special kind of coal13:55
jbenedet1owhat gets me was I cant imagine how brown the gas station attendants pants were after discovering the fire was under the station13:56
DocScrutinizer05I guess you rather need a setup that has certain properties like amount of air circulation, exceeding a certain volume, etc13:56
jbenedet1o(they mention this find in the article)13:56
jbenedet1o"John Coddington, inserted a dipstick into one of his underground tanks to check the fuel level. When he withdrew it, it seemed hot, so he lowered a thermometer down on a string and was shocked to discover that the temperature of the gasoline in the tank was 172 °F (77.8 °C)"13:56
DocScrutinizer05LOL!!!13:57
DocScrutinizer05already boiling13:57
viricand then he run away13:58
DocScrutinizer05hot gasoline, niiiiice13:58
DocScrutinizer05prolly the best he could do. after closing the tank lid again13:58
viricwhat article is that?13:59
Action: DocScrutinizer05 idly wonders where from that dude got that thermometer that had a range upto 80°C14:00
DocScrutinizer05pope fedexcus?14:05
DocScrutinizer05fedex affiliated?14:05
jbenedet1oI am the first Pope of the Church of Latter-day Deliveries.14:35
sungdo any of have the r5350 hardware design/ap design sheet?22:30
zrafakristianpaul: hey!!23:29
zrafakristianpaul: I need your help!23:29
zrafaor wpwrak ?23:35
zrafaor anybody who has tried serial in ben nanonote or sie board?23:35
zrafaWhat is the hell happening with rx pin in serial ? 23:36
zrafaI can not get bytes from it. In fact, I checked the uart status line register and it never gets the bit "data receive" bit, or whatever the name is in 1. Like if uart never receives the bytes sent to the ben or sie board.23:37
zrafaANd of course, if I try to read the data bits I get a segmentation fault or similar.23:38
