Moktato | I prefer Spacely's Sprockets | 10:57 |
Moktato | they have a nice firm texture and crunch that you just don't get from Cogsley's Cogs | 10:57 |
kanzure | hmm, 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 something | 10:59 |
kanzure | where the qr code is possibly a one-time use deal, or re-generated based on some other key | 10:59 |
kanzure | i guess you can encode a public key in the qr code | 10:59 |
Moktato | sounds like google's 2-factor auth | 11:00 |
Moktato | if it used QR codes and the camera on your laptop :p | 11:00 |

* Moktato needs to learn more about electronics. | 12:48 | |
* Moktato digs around for his one-time-use copy of Dean's Electronics. | 12:48 | |
Moktato | how 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 | <$30 | 12:52 |
strages_ | as in powered from the radio waves? | 12:59 |
-!- Steel_ [62f7762e@gateway/web/freenode/ip.98.247.118.46] has joined ##hplusroadmap | 12:59 | |
Moktato | no, such that the LED shines when a strong enough signal is received | 12:59 |
Moktato | was thinking of a way to make wireless audiostrobe glasses | 13:00 |
Moktato | combining an FM transmitter and FM receiver | 13:00 |
Moktato | and maybe a diode in there somewhere to snip out everything below 19.5khz or whatever that frequency is | 13:01 |
Moktato | or maybe use the FM signal into a transistor circuit that controls the LEDs | 13:03 |
strages_ | you want and led field strength meter then? | 13:08 |
Moktato | yes, tuned to a specific frequency | 13:10 |
Moktato | so, listening TO a specific frequency, FOR a specific frequency | 13:10 |
Moktato | RF -> Audio | 13:11 |
strages_ | something like this then http://tinkerlog.com/2007/05/20/cheap-sound-sensor-for-avr/ | 13:17 |
Moktato | kanzure: this what you were talking about earlier? http://blog.self.li/post/14864315302/qr-login#disqus_thread | 13:17 |
Moktato | strages_: yes, that looks like it | 13:18 |
* Moktato reads. | 13:18 | |
strages_ | also this http://www.scary-terry.com/more_stuff/tonedet/tonedet.htm | 13:18 |

strages_ | Moktato: are you making a sort of civiization detector? if radio frequency present, is there audio above pink/white noise?, light LED | 13:27 |
strages_ | if the light goes out, you know something's gone wrong | 13:27 |
eudoxia | can't tell if that's serious | 13:27 |
strages_ | tiny beacon telling you everything is alright | 13:28 |
eudoxia | what if civilization decides radio is too noisy and switch to laser? | 13:29 |
strages_ | then obviously it wouldn't work | 13:30 |
strages_ | lasers being highly directional and all | 13:30 |
eudoxia | how sad | 13:30 |
strages_ | eudoxia: how would you go a civilization detector in a society that uses lasers? | 13:31 |
strages_ | instead of radio | 13:31 |
eudoxia | a rover that scouts the outside of my bunker | 13:31 |
strages_ | *do | 13:31 |
eudoxia | looking for heat sources, computers, that kinda shit | 13:32 |
strages_ | EMP took out your rover, and all other complex electronics | 13:33 |
eudoxia | well that's unfair | 13:33 |
strages_ | it's within reason, as was your society of laser using audiophiles | 13:33 |
eudoxia | maybe some kind of blimp whose surface is studded with laser detectors | 13:34 |
eudoxia | powered by less-than-complex electronics | 13:34 |
strages_ | detecting lasers is very difficult if your're outside of major population points. try for something else | 13:35 |
strages_ | you have no radio and lasers are far too directional. what else do you have to work with? | 13:36 |
eudoxia | i'm thinking dammit | 13:36 |
eudoxia | heat? | 13:37 |
strages_ | you'd have to be pretty high up... | 13:38 |
eudoxia | if it's Sufficiently Advanced, they may not produce easily detectable chemical waste | 13:39 |
eudoxia | but they'll always produce some waste heat, from industrial centers or computation | 13:39 |
eudoxia | how about space activity? | 13:41 |
Moktato | strages_: wireless audiostrobe | 13:41 |
eudoxia | a little domed infrared telescope could find artificial heat sources in space, no? | 13:42 |
strages_ | eudoxia: perhaps | 13:43 |
Moktato | they might also change isotope ratios in the atmosphere | 13:44 |
kanzure | the atmosphere of earth masks a lot of the activity on the surface | 14:14 |
kanzure | so they are going to release stratfor emails? | 14:18 |

jrayhawk | do you really think the h+ community needs more ineffectual deliberation and prognostication | 23:09 |
kanzure | no. i suppose not. | 23:10 |
kanzure | friend of mine is setting up this rails bootcamp. students pay $15k for a few weeks of training. | 23:10 |
kanzure | apparently the seats are being sold very quickly | 23:10 |
Steel_ | I don't know that the h+ community needs more programmers right now | 23:10 |
-!- jennicide [jen@173-19-57-121.client.mchsi.com] has joined ##hplusroadmap | 23:14 | |
kanzure | there's hardly any? | 23:14 |
kanzure | definitely needs more mechanical engineers, lab equipmenteers, experimentalists, hackers | 23:15 |
Steel_ | eh, it honestly needs electrical engineers more than mechanical engineers | 23:15 |
kanzure | are you one of those "EEs > MEs" totem pole people | 23:16 |
kanzure | just wondering | 23:16 |
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' people | 23:17 |
Steel_ | (as an ME) | 23:17 |
kanzure | or do you have particular analog electronics projects that are currently going unbuilt | 23:17 |
Steel_ | I'm a ME, dude | 23:17 |
kanzure | let's not talk about employability | 23:17 |
kanzure | employability 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 |
kanzure | or "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 stuff | 23:18 |
Steel_ | *shrug* | 23:18 |
Steel_ | I'm a better manager than engineer, and what's more, I enjoy corporate strategy a lot | 23:18 |
Steel_ | regardless | 23:18 |
kanzure | this isn't an interview man :) | 23:18 |
Steel_ | EEs (assuming a generic undergraduate education, not a masters) | 23:18 |
Steel_ | are more important than MEs | 23:18 |
Steel_ | for h+ stuff | 23:18 |
kanzure | so 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 setup | 23:19 |
kanzure | in 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 |
kanzure | ok but again, why do you claim that EEs are more needed | 23:20 |
Steel_ | signal analysis, device building, understanding of code, electric circuit design, complex circuit stuff | 23:20 |
Steel_ | all way more important than the shit MEs learn imo | 23:20 |
kanzure | "complex circuit stuff" is a little vague, but it's mostly a bunch of graph theory and math | 23:21 |
