Mr. Powers posted:Most sensors are infrared and measure reflected light. No hands in front = no reflect light. White hands in front = mostly reflected light. Dark hands = varying amounts of reflected light that may or may not be enough to trigger. Gotcha. Thank you. I'm a moron and have no idea how things work. I thought it just sensed movement (somehow). I mean wouldn't whatever tech that makes lights come on when they sense movement be better than that poo poo? (Again, I'm a moron, I have no idea.)

Even if you assume KM got "too mad" and misread, the response was ridiculous. She is right, she gets mad one time and suddenly she is hysterical. I honestly read "before BLM" as a really lovely dig. Once again white posters get the benefit of the doubt and the black person is overreacting. That kind of thing is exactly what she talks about all the time. No one has the presence to think about why a black person is angry about (x) even if it seems unjustified. You should especially think about it then.

They're probably ultrasonic which explains why the door sensor became finnicky after putting cable races in it's field of view above the door. carticket fucked around with this message at 23:10 on Jan 27, 2019 |

But here you come running in to clarify to all of us that taxi companies and the Hamilton musical are two distinct things. Thank you for your guidance.

1glitch0 posted:activated by movement sensors. The movement sensors work by detecting lighting changes in the very cheap camera behind the dark glass built into the faucet itself. It wasn't calibrated for people with dark skins, and it's possible there's no practical way to detect black hands through black glass that won't also detect, say, a stream of water, . Computers can't recognize things visually well, and cheap computers built into plumbing are even worse at it.. There's no such thing as a movement sensor, anyway. There are heat sensors and cameras and sonar devices and laser tripwires that can be set up to react to changes in a variety of ways, and then because they keep triggering at random you have to adjust what sets them off. Maybe you get to choose between, "Black people can use this sink easily," and, "This sink doesn't waste water on false positives," and then you get to make an executive decision. And then we find out what kind of people the engineers are, and what they value most. Will their release version work but need patching so everyone can use it, or work but need patching so it doesn't waste water? And which will get the client less upset? e: 1glitch0 posted:Gotcha. Thank you. I'm a moron and have no idea how things work. I thought it just sensed movement (somehow). I mean wouldn't whatever tech that makes lights come on when they sense movement be better than that poo poo? (Again, I'm a moron, I have no idea.) Again, false positives are the issue. To a sensor hooked up to a light, basically any activity in the room means you want to have the lights on in there, so false positives aren't a big deal. But you can't set a sink to turn on any time it detects any activity, or it'll turn on when people walk past the sink, or a reflection in the sink bowl shifts, or when there's water falling in front of the sensor and splashing, which would mean it wouldn't turn off. So you have to use a sensor that's less sensitive and harder to trigger. Mystic Mongol fucked around with this message at 23:17 on Jan 27, 2019 |

not to get away from the inherent racism in them, but on those faucets, shouldn't it also be addressed that there's no redundancy? even autoflush toilets have a button you can hit if it doesn't trigger. why don't (most) automatic sinks, soap, paper towels, etc, have a redundant way to trigger it? that doesn't solve the bigger issue of the sensor, but still.

That is exactly what I did. It was a little awkward using my phone camera in the bathroom to see if I could spot the paper towel sensor, which I couldn't. I also have night vision googles and they didn't pick anything up in the lab.

1glitch0 posted:Yeah, I didn't get into how Uber and Lyft have made things a lot of worse for workers. It's amazing how they get away with it just because it's an app. There's a reason the taxi medallion system was put in place in so many cities. It's not a perfect system especially with all the corruption (like when news came out Michael Cohen was involved in taxi medallions it was like OF COURSE he was), but there is a good reason for the system. The drivers get paid poo poo and Uber and Lyft get so much money for doing pretty much nothing. Uh, my brother drives with Lyft and Uber, and I have to say 100% gently caress the taxi industry. And he *crushes* out ~$1200-1500/week in the metropolitan area we live in. I also dated a taxi driver for ~5 months in NYC, and from that (granted its anecdotal) experience I can say the taxi industry is sketchy as gently caress. Before uber made taxi drivers irrelevant anyways, the medallion hustle and leasing of medallions and control that gave Capital was bullshit. Sorry that taxi drivers don’t get their boomer retirement “guarantee” they thought they had, while at least a substantial amount acted like pricks, with little to no oversight or consequences for how they treated the customer. Ride sharing wouldn’t be the success it is if it wasn’t such a *drastically* better option for the consumer. The taxi industry can die with coal as far as I’m concerned.

Yeah but a physical button would be more reliable. Like unless you've worked with them it's hard to understate how finnicky and unreliable IR sensors were. Before I flunked out of Electrical Engineering I had to build projects that required IR sensors. One was using a sensor to have a robot car navigate around IR flashing beacons...only the test was outside and none of the professors who assigned us the parts list realized that daylight would flood and blind the sensor. Another was making a barcode scanner where we discovered that laminating our test cards made them unreadable to the IR sensors we had. Though on the plus side we made our professor laugh when we told him with a straight face that 50% of the time our project worked 100% of the time, and then proved it (the scanner scanned and sorted the cards perfectly...when it didn't kick them out for a read error due to being our dirty, over-used test cards and not the fancy laminated ones that didn't work). Also as an Amazon box packer now, I feel anyone who believes an IR barcode scanner can pick up black ink on brown cardboard with ease deserves a serious shin kicking. I can fully believe that those thing are utter poo poo if your skin is less than lilly white like mine.

What's the chances of Trump shutting down the govt in 3 weeks? The narrative being pushed by the T_D crowd now is that he "fooled" the Dems by agreeing to a truce to gain the SOTU. Once the 3 weeks is up he will continue the shut down. I'd like to see Pelosi schedule the SOTU just after the 3 week deadline, and pull the rug out from under him if he starts another shut down.

How much is this depreciating his car at no cost to Uber/Lyft? Does he get health insurance? What if he's assaulted on the job, or injured, does he get workmans comp? Just fyi its possible the end user experience is better and Uber and Lyft are still lovely solutions to human transport, which function primarily by taking away the protections which workers employed. Like, it's lovely in a different way, but less lovely, is still a bad solution but its the kind of "solution" that capitalism generates.
