2014-02-28 00:21 <wpwrak> flash-heat it so that the water/solvent evaporates instantly, forcing the paint onto the pcb :)

2014-02-28 00:38 <DocScrutinizer05> of course you also could use a multilayer PCB and cut trenches at least through 2 copper layers, then you could apply high voltage to both layers to create a tiny spark in each trench that would "explode" the paint out ;-P

2014-02-28 01:10 <wpwrak> hah, i have the solution. take a thin copper sheet. apply etch mask leaving only the silk exposed. place copper sheet on PCB. then take paint, 35% HCl, and 50% peroxide, mix, and apply evenly to the copper. with so much peroxide, the acid will wolf down the copper in a second or so, which is very exothermic, so the acid will boil off, leaving only the paint. problem solved.

2014-02-28 11:52 <whitequark> nah, yuan is tightly controlled. Pretty sure this was planned
2014-02-28 11:54 <nicksydney> whitequark: true it "can" be controlled and it will be but again at what cost to the govt as US is tapering
2014-02-28 11:56 <whitequark> well, perhaps
2014-02-28 12:06 <nicksydney> Major bitcoin exchange Mt.Gox, has lost nearly all the virtual currency held in its systems ... http://www.cnbc.com/id/101455170 ... as expected....now here comes the crash !
2014-02-28 12:07 <whitequark> no, it does not
2014-02-28 12:07 <whitequark> the "crash" has already happened, and it was about... 12 hours long?
2014-02-28 12:08 <whitequark> if by "crash" you mean "dropped from $550 to $400", of course.
2014-02-28 12:08 <whitequark> mtgox is but one player, and not the most important one for sure
2014-02-28 12:09 viric has quit [Ping timeout: 240 seconds]
2014-02-28 12:11 <nicksydney> whitequark: this will change the playing field and now the "authority" will have an excuse to "crush" bitcoins as they are waiting for the right reason to do this
2014-02-28 12:12 <whitequark> "authority" doesn't need an excuse. that's because it is authority.
2014-02-28 12:12 <nicksydney> or at least they will be put under the microscope and they will start regulating the virtual currency
2014-02-28 12:13 <whitequark> you do realize mtgox was heavily regulated, don't you?
2014-02-28 12:13 <nicksydney> now they have a "solid" excuse to do it so they cannot be blamed when it happens :)
2014-02-28 12:13 <whitequark> bullshit. countries have banned bitcoin on a whim in the past. this doesn't change anything
2014-02-28 12:14 <whitequark> and it's not like mtgox is the first bitcoin-related business to go broke
2014-02-28 12:14 <wpwrak> i concur. mt. gox doesn't matter (except to those who had their coins there)
2014-02-28 12:14 viric has joined #qi-hardware
2014-02-28 12:16 <whitequark> some didn't even have to ban it. e.g. after bank of russia issued an "advice" about bitcoin, all exchanges I know have self-regulated, where by "regulated" I mean "stopped doing any business in RU"
2014-02-28 12:16 <wpwrak> the main problem with mt. gox is that many people - like nicksydney does - think it's important. of course, that's who currencies work - if nobody believes they'll get something for a given currency, it has no value. self-fulfilling prophecy at its finest :)
2014-02-28 12:17 <wpwrak> whitequark: well, "russia", "advice", "self-regulation" ;-)
2014-02-28 12:17 <whitequark> the "advice" boiled down to "bitcoin is mainly an instrument of speculation", which is kinda even true, and it did not have any legal consequences for those operating. alas, that's how RU works.
2014-02-28 12:17 <whitequark> (mtgox is important) well, market doesn't consider it very important--see for yourself.
2014-02-28 12:18 <wpwrak> yes, it's mainly in the "man on the street"'s opinion
2014-02-28 12:18 <whitequark> the problem with mtgox always was lack of liquidity. you could withdraw USD two times a year.
2014-02-28 12:19 <nicksydney> wpwrak: changing a mindset that has been established for hundred of human years can't be done within few years same with regulation...no matter how much you want to go against it won't be able to alter it...probably it make a dent
2014-02-28 12:20 <whitequark> and only after jumping through absurd legal hoops
2014-02-28 12:20 <whitequark> nicksydney: bitcoin isn't fundamentally against regulation
2014-02-28 12:20 michael_lee has quit [Ping timeout: 244 seconds]
2014-02-28 12:21 <whitequark> take a look at US startups working with bitcoin. all of them invariably have to deal with taxes, regulation, identification and the like. this doesn't diminish usefulness of bitcoin.
2014-02-28 12:21 <whitequark> it's very much like cash in that regard
2014-02-28 12:23 <nicksydney> gold, silver, copper and oil is the same like bitcoin which cannot be traded on physical level but it can be "transacted" and can be taxed however it takes a LONG time for people to accept that it can be "transacted"
2014-02-28 12:24 <nicksydney> don't see any productive value in Bitcoin...better off investing in farms :)
2014-02-28 12:25 <whitequark> until about 1970, USD was literally transacting gold
2014-02-28 12:25 <nicksydney> seems like the Chinese IC vendors are really kicking into high gears http://www.cnx-software.com/2014/02/28/mediatek-smartphone-soc-roadmap-until-2015/
2014-02-28 12:25 <whitequark> it is already accepted
2014-02-28 12:25 <whitequark> productive value? take a look at paypal. try to accept money from someone. then come back and say bitcoin is useless :p
2014-02-28 12:26 <nicksydney> well paypal is a means to "transfer" from one account to another not a currency that you can convert to :)
2014-02-28 12:26 <whitequark> in other words, main value of bitcoin for a consumer is that they do actually keep their money themselves, not in hands of some third party which can freeze or forfeit their assets on a whim
2014-02-28 12:28 <whitequark> sure. it is however true that you cannot transfer dollars online without trusting them to some third party, who more often than not would be borderline hostile to you/
2014-02-28 12:29 <whitequark> (well, there are some experiments in that direction, e.g. Ripple. we'll see how they fare)
