Back
[00:37:47] <Jak_o_Shadows> I am back
[00:37:53] <Jak_o_Shadows> I really need to get that irc bouncer working
[00:50:16] <Wetmelon> welcome back
[00:50:51] <rue_house> wuff, 4 bit sine wave is crude
[00:51:02] <rue_house> can hear the distortion
[00:51:54] <rue_house> wow, a few 100Hz gives me a headache
[01:11:27] <Jak_o_Shadows> Picking up untested code from a week ago
[01:11:40] <Jak_o_Shadows> I understand what it's doing, and I don't think it's doing it in a bad way, i'm just not sure it was ever quite correct
[01:11:45] <rue_house> my max548 code works
[01:15:08] <Jak_o_Shadows> Oh, I hadn't finished
[13:24:44] <doomlord> have there been any experiments with 'giant slotcars' for transport (electric + 'self-drive')
[13:27:12] <z64555> Yeah, they're called monorails
[13:27:13] <z64555> :D
[13:28:10] <z64555> eh, I'm not entirely sure what you mean by "self-drive" though.
[13:29:31] <z64555> problem with up scaling slot-cars is building the track, it can be expensive, and very limited to destinations
[13:30:26] <z64555> Which is probably the reason why there's so much focus on self-driving automobiles, because you have an autonomous vehicle that makes use of existing roads and highways
[13:31:11] <z64555> Some of the simpler ones can use RFID tags embedded in the asphalt to aide their tracking systems
[13:31:22] <z64555> which is effectively a slot
[13:33:31] <z64555> A simpler implementation would be line-follower bots, which follow a painted line
[13:58:06] <anniepoo> I've often wondered, for decades, why we didn't implement the obvious solution of line following cars.
[14:01:49] <z64555> Line follower cars would be severely limited to pavement. There's also the issue of cameras being able to pick up the lines in incliment weather, and also road damage
[14:02:31] <z64555> There's also the need for quite a bit of paint in order to determine which exit to take
[14:03:55] <anniepoo> makes sense
[14:04:16] <jesseg> It takes a massive invenstment of technology. If it's done in the car to use legacy roads, when it has to be massively complex in order to deal with what we humans take for granted and/or crash because of.
[14:04:50] <jesseg> If it's a simple mechanism in the car, then massive outlay of infrastructure is needed in the roads -- but it sure could be done
[14:05:13] <z64555> yes
[14:05:26] <jesseg> there could be buried transponder coil rows in the center of the lanes, and could communicate turn points, etc.
[14:05:50] <jesseg> But it'd require tearing up all the roads :D
[14:06:20] <z64555> vs. the RFID tags, which is as simple as shooting a nail deep into the asphalt
[14:06:21] <jesseg> and it'd have to be done across a large part of the country to be useful
[14:06:49] <anniepoo> yes, hence the paint. I suppose then it has to be able to cooperate with cars not so equipped
[14:07:01] <z64555> aka, human driven cars
[14:07:20] <z64555> we'll just ignore the poor amish
[14:07:37] <anniepoo> right - and poor people
[14:07:37] <z64555> They already have self-driving cars, anyway
[14:09:27] <anniepoo> farmers and logging equipment, deer and elk (a real issue round here), cattle (this is open range)...
[14:10:29] <anniepoo> I can't see the roads at all now, and haven't for over a month. I see, depending on the day, anything from a firm pack of snow left by the plow to big mountains of the stuff
[14:10:50] <Snert> Amish use horses in their vehicles. Seem to do pretty well with all kinds of obstacles.
[14:11:21] <anniepoo> I've wondered about self driving cars. If the car gets in trouble and asks the driver to take over, and the driver's drunk,
[14:11:36] <anniepoo> and crashes, is it the driver
[14:11:40] <anniepoo> driver's fault?
[14:12:26] <Snert> opinion - driver did not inform car of intoxication like he should have. So yes, driver fault.
[14:14:04] <Snert> actually I think it's implicit in "there must be a licensed driver ready at all times" clause.
[14:16:18] <z64555> yup
[14:18:19] <Snert> but will that clause always be there? Would you ever throw your 2 kids in a robocar and send it off to deliver the kids ?
[14:19:31] <Snert> I'd have a hard time trusting that.
[15:02:28] <z64555> versus sending your kids off to school on a bus, with a driver who is known to be intoxicated?
[15:05:32] <deshipu> versus driving them yourself, being tired and intoxicated too
[15:05:47] <z64555> yes
[15:06:29] <z64555> trust is gain through action, not promises
[15:06:38] <deshipu> on the other hand, in countries that have actually functioning public transport, the accidents with it are very rare
[15:07:06] <deshipu> z64555: actually, the funny thing with trust is that it goes both ways
[15:07:10] <z64555> Regardless of who or what is driving it, if they prove to be a safe driver and competant, it doesn't matter
[15:07:25] <z64555> deshipu: well, yeah, but that's a tangent :P
[15:07:28] <deshipu> z64555: that's why it's not possible to "trust" a company or a machine
[15:07:43] <deshipu> z64555: you can only accept the risk involved
[15:08:02] <deshipu> it's one-sided
[15:08:42] <rue_house> and what about having a sober bus driver hit by an intoxicated one
[15:08:57] <rue_house> what is the buss it hit by a metior?
[15:09:16] <rue_house> or a sinkhole opens up under it and it plummits into the earth
[15:10:05] <rue_house> what if the mechanic was told not to just tape up a leaking brake line and the tape fails and the bus crashes because of it
[15:10:10] <rue_house> hey, happens on planes
[15:11:19] <rue_house> there is no 'safe' 70% of the population is screwed up in some way from something that the medical system wouldn't fix.
[15:12:23] <rue_house> prolly 3% of cars on the road are about to have their engine blow up cause there is no oil in it, and its being driven anyhow
[15:13:13] <Tom_itx> no work?
[15:13:19] <rue_house> its dead
[15:13:26] <rue_house> I'm waiting for parts
[15:14:39] <rue_house> and I might be comming down with a flu
[15:14:52] <rue_house> something is attacking me
[15:15:21] <rue_house> heard from kat?
[20:54:56] <anniepoo> ok, progress on the exterior design
[20:54:58] <anniepoo> http://partyserver.rocks/anniepoo/snailinesspic.png
[20:55:47] <z64555> looks like a hungry snail
[20:55:55] <anniepoo> 8cD
[20:56:09] <anniepoo> >8@_
[21:14:07] <z64555> what was that? D:
[21:17:24] <anniepoo> I'm building it
[21:17:25] <anniepoo> 8cD
[21:25:48] <z64555> out of emojis? That's groundbreaking!
[21:26:02] <anniepoo> lol
[21:26:22] <anniepoo> yes, I'll be building the whole thing, including processors, out of emojis
[21:31:54] <anniepoo> 8888 <-- battery pack
[21:32:13] <anniepoo> [~~o] <-- processor
[21:32:30] <anniepoo> OOOO <-- treads
[23:59:59] <rue_shop3> hah
