pikma commented on Caltrain's new electric trains   fastcompany.com/91174458/... · Posted by u/kaycebasques

> For example, last week the blog pointed out that the new trains take an extra 8-10 seconds after stopping at a station to begin opening the doors

Anecdotally, this is also true of the San Francisco Municipal subway. The subway cars take a long time to open and close doors because there is a mechanical bridge that closes the gap between the train and the platform. This is also a pretty big time sink for the subway system

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.

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?

Are there discoveries or theories from the field of psychology that are (a) not obvious and (b) generally regarded as correct?

For example, things like general relativity, continental drift, or evolution from the fields of physics, geology, and biology.

Does psychology have anything like that?

pikma · 2 years ago
Not a psychology researcher, but I think that the Milgram experiment has been fairly well replicated. Please anyone let me know if not.

I personally found it to be non-obvious.

From https://www.npr.org/2019/09/18/762046422/the-chess-grandmast...

> Chess grandmasters spend hours sitting over game boards. And yet, high-level players lose 10 to 12 pounds on average over a 10-day tournament.

There's another thread linking the same article, and it's very unclear that this loss of weight is caused by the mental effort.

If thinking hard required a lot of energy, wouldn't we expect that thinking hard would cause an increased heart rate and faster breathing?

Because it takes energy? This is pretty well observed in high level chess[1].

Last week, a drug-addicted homeless woman gave birth to a baby on the street in SF like an animal. It's worse than a 3rd world country in SF these days.

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?

> nothing would have come of it had they not traced the guy

Notify the cops. Track the guy down. Go to the station and request someone come out with you. This takes cops off the desk, which they’re rarely against unless you’re a nutter.

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.

Trust me, you accept the beating. The alternatives and escalation path was not something you wanted to explore. My school had waterboarding on the menu, for instance, which I cannot recommend.

And no, you can’t retaliate in secret by putting thumbtacks in the master’s shoes - that just results in cohort punishment and witch-hunts by your fellow pupils who want to skewer whoever is responsible for bringing down the wrath of god upon them.

Fear is an exquisite control mechanism.

"My school had waterboarding on the menu".

When and where did you go to school?

pikma commented on CarSized: A way to visualise car dimensions   carsized.com/en/... · Posted by u/kennybrea
losvedir · 3 years ago
Very cool! I just did some car shopping and compiled a spreadsheet of the various dimensions of the cars we were considering. This would have been a perfect tool for us. It's kind of hard to really get a sense of the numbers otherwise. Looks like it doesn't have a way of visualizing interiors, unfortunately.
pikma · 3 years ago
+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).

I couldn't find that at the time sadly.
