In contrast, in the metro in Paris, the doors open a few seconds before the train stops, so that the doors are fully open by the time the train is stopped - and passengers in a hurry can jump out while the train is still moving.
Not sure if they still have the wooden cars on the A (blue) Subte line in Buenos Aires. I lived in Caballito for a little while in 2007 and got a huge kick out of opening the doors early, hopping off the train and sliding on the platform with my crappy slippery shoes.
In Berlin (and probably other German subway systems, can't recall) you can trigger the open doors handle/button a few moments before the train completely stops, similar concept to Paris.
I experienced a few German S-Bahn systems. Berlin's seems to be the only one that doesn't use trains similar to the regional ones, which have the delay.
I absolutely want to do something like this to help me and my family spend less time watching our phones in the evening.
Does anybody know of a reasonably-simple way of either increasing the latency or throttling the bandwidth, per-device, with programmable hours? For example, is there any wifi router that lets you do this?
Milgram's results are also not as cut and dry as they are usually presented. Obedience rates varied wildly in subsequent variations he ran of the experiment and his initial experiment that got all the attention was a pretty low sample size.
“Many of Milgram’s participants believed it to be impossible that the prestigious Yale University experimenter would allow real harm to be inflicted on an experimental subject. Although Milgram claimed that 75% of his participants thought they were administering painful shocks, Perry’s re-analysis of the data showed that “It’s more truthful to say that only half of the people who undertook the experiment fully believed it was real, and of those, two-thirds disobeyed the experimenter” (p. 163). Furthermore, she argues that many of those who did administer the maximum amount of shock did so because they were confident the shock wasn’t real or that the experiment was an elaborate ruse.”
That's still a shocking (no pun intended) percentage of people willing to inflict what they think is pain on another human based merely on the orders of an authority which they are not truly obliged to follow. I imagine the percentage of willing participants would be even higher if they had a real reason to follow the orders, e.g. it was actually their job and/or they would be punished in some way for failing to follow orders, as was the case in Nazi Germany.
Remember his initial experiment was only 40 people, so we’re talking 6 individuals who could very easily been outliers.
And I have my doubts that any of those 6 actually completey believed that a Yale psychology experiment was allowed to dangerously shock students, or that the student actors were all that believable.
It is a bit confusing to me because it is often said that the brain draws about the same amount of energy, no matter what. Perhaps people also eat less during tournaments.
the brain has enough blood and oxygen, it uses that to depletes other resources when firing
so no.
think of it like a computer, drawing more electricity faster won’t help the physical properties of the RAM or transport bus (much). it already has enough of that, the bottleneck is elsewhere. but good breathing does help cognition
compared to muscles the brain is a small surface area with a wide bus. when exercising, the demands are about getting more oxygen to more muscles, which is merely transported by blood, and the heart beats faster to pump blood faster, the breathing is an attempt to oxygenate more blood. thats the difference between muscular activity and brain activity
This is horrible. I see horrible scenes in the city streets on a regular basis but seeing the picture of this poor tiny little baby on the pavement hit me hard.
Anybody here had experience dealing with that kind of cold? I'm curious how people deal with with. Is that something that good equipment can protect against or is it just too cold?
I lived in the Yukon for 4 years, rode my bike to work every day of the year, it was often past -40C/F in winter. With good clothing that was perfectly fine, and I enjoyed it. Watching the steam and huge chunks of ice on the Yukon river is a sight to behold. Also seeing the northern lights on the way to work at 8am is great, as-is seeing the lights or stars again at 4pm.
With far from the best gear I can stand around outside happily down to about -30C. Past that, I need to be near a fire, or moving (snowshoeing, riding, cutting wood) to stay warm to about -40C/F. After that I have to really move to stay warm enough for a long period of time. Once I was caribou hunting just below the Arctic Circle in late November (the sun only came up for about an hour) and it was something like -50C (-58F). Try as I might, I never did warm up even jogging on the spot, jumping jacks, etc. etc.
In the north most people don't even really consider will chill, because it's kind of meaningless - it officially has no units and is an estimate at best. Northerns take pride in being "tough" and most people say stuff like "Wild Chill is for people who get cold", or something similar.
So there were many days the actual temp was -46C (-50F), and if the wind was coming from the North it was stupid cold. The will chill would have been well past -60C (-76F), but nobody talks about it. On those days it's very hard to be outside for long, and exposed skin is an absolute no-no. If I took my two layers of gloves off to do anything I'd lose feeling in my fingers for hours and they really, really hurt.
Interestingly, the temperature between night and day only changes a degree or two - the sun makes virtually no difference, even though the colder it gets the clearer it gets. I grew up in Australia, yet the most stunning blue sky days of my life were in the Yukon past -40C/F.
I lived not too far from Snag, Yukon, the coldest ever recorded place in North America at -63C/-81F [1]
I should also add that Yukon has no concept of "too cold for school" or work, or anything like that. It's perfectly normal to go to school or work when it's below -40C/F, everyone just deals with it. It's amusing when it warms up to -20C or -30C and it feels comparatively balmy!
I spend hours outside at -10F skiing… it’s usually some of the best conditions (partly because nobody is there). I’m not just warm, but pretty much as comfortable as being inside.
I was also out last night in -20F taking the dog out before bed, I’ve got a full-body arctic suit for such occasions (and he does too).
Good cold weather gear is pricey, but it makes all the difference. It lasts for a long time, so it’s a good investment if you have to deal with these temps during the year.
I saw the mercury drop from -25C to -35C on the bus from Changchun to Haerbin once (the buses, for some reason, had digital outside temperature thermometers up front). I was dressed for it well enough, but I didn’t keep my phone or camera warm enough, so I didn’t get many pictures of the ice sculptures I went to see. Too far south for northern lights though, weird it would get that cold at that latitude.
Northeast Asia has perfect conditions for terrible winters. Continental climate (so it gets extremely cold), the prevailing winds don't bring in moisture, and the Siberian anticyclone just adds to the frigid ambiance.
Lithium batteries have really really bad performance in cold weather(not even talking -40, like 32 degrees for 10 minutes out and your phone will absolutely shrivel)
In the coldest days of NYC winters my Nexus 6p would reboot if I tried to use the camera. In cold conditions lithium batteries have difficulty keeping voltage steady when there's a sudden amperage spike from turning on the camera hardware. If it gets even colder just turning on the screen can cause the voltage to drop enough that the phone will malfunction.
I’d run across a courtyard in a tshirt when it was -40 for fun. Invigorating :)
Yes, managing being outside in the -40s is doable with above average equipment but nothing crazy. Good insulation isn’t all that hard. I have a coat that I have to have unzipped at 0F because I get hot.
100 mph winds on the side of a mountain is a challenge at any temperature.
When is that cold you just have to be careful or a mistake can lead to permanent damage in seconds or minutes, the cold will kill you easily and you’re just very aware of it when you’re out in it. Surviving isn’t hard but deadly mistakes are also easy.
It also has a lot to do with attitude. If you think it’s the worst suffering it will be.
You’ll want insulated boots, thick wool socks, insulated pants, a parka, layers under the parka, gloves with mittens over, face covering, hat.
Keeping your face, head, and feet warm are the most important. Next is much torso insulation.
Not a ton, but I've done it. The basic approach: wool, wool, thinsulate if you're fancy, more wool, in layers. Something that effectively blocks the wind on top. No cotton. Good boots and gloves. Make sure you've got no exposed skin.
Where do you live? In SF, last time I tried to get the cops to come out of their desk (to arrest a bike thief who was selling my stolen bike literally 3 blocks away from the station), they told me that they couldn't do it. One of the excuses they used was that it was too far: if I could get the thief to enter the police station then they would help me.
SFPD is notoriously, maliciously useless. It's a political tactic that they've used to wring more funding, less oversight and fancy surveillance gadgets from the city. The previous DA had to rent a U-Haul himself to seize stolen property from a shady business[1] that was involved in organized car breakins. In 1975 they set a bomb off on the mayor's lawn to get him to concede to their strike demands[2].
They're not there to help you, little bike owner. They're there to ensure the value extraction and capital accumulation machine stays lubricated.
+1, this would have been super to me too when buying a car with the constraint of having a tiny garage with a weird shape.
What I really wanted was a tool that lets me draw the plan of the garage and then tells me if I'll be able to park my car, and the margin (min offset to wall during the whole maneuver).
