Moktatoit's sort of like a sprocket10:36
kanzurethe context is like a sprocket?10:42
kanzure"Cheetah from the 1930's B&W Tarzan movies has died at age 80 of kidney failure today"10:42
MoktatoI prefer Spacely's Sprockets10:57
Moktatothey have a nice firm texture and crunch that you just don't get from Cogsley's Cogs10:57
kanzurehmm, so what is the class of security scheme where you have a device (like a smartphone) rendering your qr code, and have your other computer scan the code to log you into something10:59
kanzurewhere the qr code is possibly a one-time use deal, or re-generated based on some other key10:59
kanzurei guess you can encode a public key in the qr code10:59
Moktatosounds like google's 2-factor auth11:00
Moktatoif it used QR codes and the camera on your laptop :p11:00

* Moktato needs to learn more about electronics.12:48
* Moktato digs around for his one-time-use copy of Dean's Electronics.12:48
Moktatohow hard d'ye think it'd be to rig up a cheap dollar-store FM radio to run a couple of LEDs?12:50
kanzure<$3012:52
strages_as in powered from the radio waves?12:59
-!- Steel_ [62f7762e@gateway/web/freenode/ip.98.247.118.46] has joined ##hplusroadmap12:59
Moktatono, such that the LED shines when a strong enough signal is received12:59
Moktatowas thinking of a way to make wireless audiostrobe glasses13:00
Moktatocombining an FM transmitter and FM receiver13:00
Moktatoand maybe a diode in there somewhere to snip out everything below 19.5khz or whatever that frequency is13:01
Moktatoor maybe use the FM signal into a transistor circuit that controls the LEDs13:03
strages_you want and led field strength meter then?13:08
Moktatoyes, tuned to a specific frequency13:10
Moktatoso, listening TO a specific frequency, FOR a specific frequency13:10
MoktatoRF -> Audio13:11
strages_something like this then http://tinkerlog.com/2007/05/20/cheap-sound-sensor-for-avr/13:17
Moktatokanzure: this what you were talking about earlier? http://blog.self.li/post/14864315302/qr-login#disqus_thread13:17
Moktatostrages_: yes, that looks like it13:18
* Moktato reads.13:18

strages_Moktato: are you making a sort of civiization detector?  if radio frequency present, is there audio above pink/white noise?, light LED13:27
strages_if the light goes out, you know something's gone wrong13:27
eudoxiacan't tell if that's serious13:27
strages_tiny beacon telling you everything is alright13:28
eudoxiawhat if civilization decides radio is too noisy and switch to laser?13:29
strages_then obviously it wouldn't work13:30
strages_lasers being highly directional and all13:30
eudoxiahow sad13:30
strages_eudoxia: how would you go a civilization detector in a society that uses lasers?13:31
strages_instead of radio13:31
eudoxiaa rover that scouts the outside of my bunker13:31
strages_*do13:31
eudoxialooking for heat sources, computers, that kinda shit13:32
strages_EMP took out your rover, and all other complex electronics13:33
eudoxiawell that's unfair13:33
strages_it's within reason, as was your society of laser using audiophiles13:33
eudoxiamaybe some kind of blimp whose surface is studded with laser detectors13:34
eudoxiapowered by less-than-complex electronics13:34
strages_detecting lasers is very difficult if your're outside of major population points.  try for something else13:35
strages_you have no radio and lasers are far too directional.  what else do you have to work with?13:36
eudoxiai'm thinking dammit13:36
eudoxiaheat?13:37
strages_you'd have to be pretty high up...13:38
eudoxiaif it's Sufficiently Advanced, they may not produce easily detectable chemical waste13:39
eudoxiabut they'll always produce some waste heat, from industrial centers or computation13:39
eudoxiahow about space activity?13:41
Moktatostrages_: wireless audiostrobe13:41
eudoxiaa little domed infrared telescope could find artificial heat sources in space, no?13:42
strages_eudoxia: perhaps13:43
Moktatothey might also change isotope ratios in the atmosphere13:44
kanzurethe atmosphere of earth masks a lot of the activity on the surface14:14
kanzureso they are going to release stratfor emails?14:18

kanzureno no i said *ignore* it22:29
Mokbortolanhttp://www.youtube.com/watch?v=X6Sawj0HyF022:30

sylph_makoOh this sounds interesting.22:57
jrayhawkthat sounds like a terrible idea23:04
kanzurethey will commit mass suicide when they realize they would be a morally corrupt ai?23:05
jrayhawkdo you really think the h+ community needs more ineffectual deliberation and prognostication23:09
kanzureno. i suppose not.23:10
kanzurefriend of mine is setting up this rails bootcamp. students pay $15k for a few weeks of training.23:10
kanzureapparently the seats are being sold very quickly23:10
Steel_I don't know that the h+ community needs more programmers right now23:10
-!- jennicide [jen@173-19-57-121.client.mchsi.com] has joined ##hplusroadmap23:14
kanzurethere's hardly any?23:14
kanzuredefinitely needs more mechanical engineers, lab equipmenteers, experimentalists, hackers23:15
Steel_eh, it honestly needs electrical engineers more than mechanical engineers23:15
kanzureare you one of those "EEs > MEs" totem pole people23:16
kanzurejust wondering23:16
Steel_I'm one of those 'the education that an EE receives is currently more employable and relevant than the education that an ME receives' people23:17
Steel_(as an ME)23:17
kanzureor do you have particular analog electronics projects that are currently going unbuilt23:17
Steel_I'm a ME, dude23:17
kanzurelet's not talk about employability23:17
kanzureemployability is just a made up term to mean "I don't want to go raise funds to build this shit on my own"23:17
kanzureor "i'm poor and/or don't have enough money to finance this myself"23:17
Steel_or if you want to get into an executive position so that in 20 years we have major corporations doing this stuff23:18
Steel_*shrug*23:18
Steel_I'm a better manager than engineer, and what's more, I enjoy corporate strategy a lot23:18
Steel_regardless23:18
kanzurethis isn't an interview man :)23:18
Steel_EEs (assuming a generic undergraduate education, not a masters)23:18
Steel_are more important than MEs23:18
Steel_for h+ stuff23:18
kanzureso again, what specific projects though?23:19
Steel_I'm not currently working on any engineering projects outside my thesis, though there's a possibility of a desktop SLA setup23:19
kanzurein general i find that most MEs worth their salt can stomp through horowitz or any other analog study material (same with EEs of course; it's just some course specialization really)23:19
kanzureok but again, why do you claim that EEs are more needed23:20
Steel_signal analysis, device building, understanding of code, electric circuit design, complex circuit stuff23:20
Steel_all way more important than the shit MEs learn imo23:20
kanzure"complex circuit stuff" is a little vague, but it's mostly a bunch of graph theory and math23:21
