(Chinese but since it's esp32 and raspberry pi it is possible to tinker with it)

I wonder what's the catch? Cheap IMU/motors?

Some people have friends, and some people also have friends that are very distant (geographically, life style, stage of life, etc).

Social media can allow you to keep in touch with these people in a very convenient way. For me, being able to see life updates of friends with 8h+ timezone differences is very nice perk, because planning a call or having energy to chat with someone that far away is tricky and many people understandably then drop it if that's the only way. (same applies if I want to talk to my digital nomad friend or, new-dad-overwhelmed friend). It's much easier to facilitate meeting up when I'm traveling too.

But even for people that want to use it for that purpose only, FB/Instagram will shove down infinite scroll and stories/reels/updates of people/entities you can care less about.

And yes for some it is hard to have "the willpower" as you want to frame it. (although we know it's not so much willpower, from addiction studies around nicotine and how loss of socialization around smoking usually is a detriment to quitting smoking for example)

And yes just removing / blocking those features help. There are also unofficial side-loadable app out there. So for me it works.

And for your life maybe there's no loss in socializing by just walking away. Good for you. But maybe the examples can shed some light in how social NETWORK (social media before algorithm and attention economy) is useful for many in different predicament than you, while the social media aspects, many would rather opt out.

And unfortunately only a select few of my friends (nerds/techies) are outside it (signal, discord, good old email) but almost everyone at least have an account. Many of the people I know move often enough that phone numbers aren't even a reliable way to keep in touch

So meta won.

The only thing I'm asking for is better control over my social media. Let me remove infinite scroll on Instagram and don't show me things I have explicitly followed on Facebook. And do this setting by default and a cigarette like warning pop-up when you try to enable the algorithms.

(I know you can do this with custom apps and I'm doing that but you have no clue how many non tech people beg me to share how and then cop out when they learn you have to download custom apk. Just add these functionalities as an default )

They just showed their delinquency very differently. Some weird form of "honor among thieves/不良/yakuza" deal, which mostly meant they were aggressive, hanged out late (loitering around convenience store asian squatting with a cigarette in their hand) and driving around in loud bikes and fight each other. Breaking public things was a rare overstep.

So I still don't get it no. There are many ways to have "delinquent fun" so to say, so why at one place the same need is put out on public things vs the other place it is taken out on... Each other(?) is a mystery to me.

>Tell me, how does the whole 'kids take care of their own bathrooms' thing work out for bullies?

This is the most predictable counter argument I get when the public responsibility in school in Asia is brought up, and it sounds fair on the surface on it but it is a red herring; bullying exist independent of collectivism or individualism nor collective responsibility or not, and neither address it, and neither is anyone claiming it addresses bullying.

And no bully don't usually love it. Because there's something called a teacher that checks in if everyone is doing their part and if a malicious actor is not, they get reprimanded. This is ofc not perfect and doesn't solve "teachers pet/favoritism" issue, but it does its job of teaching the students that "if everyone collaborate, one can circumvent race to the bottom Nash equilibrium when no one cleans the room." which I would say is a much better systemic approach than "idk individualism, things are shit because we are too lazy to think about responsibilities nor systemic way to uphold some trust in social settings"

"If your system is built on the assumption of every actor acting ideally, that's a broken system."

One thing that perplexed me endlessly during my youth living in Sweden was seeing drunk teenagers go around vandalize things for... Fun. Breaking the glass at the buss station (designed to shatter in to million pieces so you don't hurt yourself), friends enjoying graffiti, littering, throwing beer bottles on the street for fun....

During public school lunch (I only heard my friends doing it) they had "meatball war" throwing meatball at each other for fun. Justification was that school lunch taste shit so it's ok to throw food. Mind you all this was in the district with highest median earning in the entire country, not a ghetto.

Same for toilet. Just why did you need to rip off that toilet lid?

Collective ownership and responsibility is taught. In most Asian countries kids are often tasked to clean their own classroom. If someone then just destroys things for fun everyone suffers. EU/US just think that's dumb thing to teach because "eww collectivism" and even the weird conservative people going on about rules usually don't even want that.

So you have a society where race to the bottom is inevitable when it comes to caring for public utilities. "privatized profit(fun) , socialized loss" teaching starts even before economics class

Maybe I work in a different field but last year when I was still looking for jobs, only one company asked for coding assignment and every other company did coding interview which is always browser based editor.

I feel like the industry is mature enough that you can tell a company that sends you a zip file of code to f-off.

If there's a text to speech for rapping I'd really love to insert your sentence.

Turns out Tukey is visualizing looking at a tape, while he counts, while Feynman imagined himself talking to himself, so he couldn't speak while counting but Tukey couldn't read while counting

>By that experience Tukey and I discovered that what goes on in different people's heads. when they think they're doing the same thing - something as simple as counting - is different for different people. And we discovered that you can externally and objectively test how the brain works: you don't have to ask a person how he counts and rely on his ownobservations of him-self; instead, you observe what he can and can't do while he counts. The test is absolute. There's no way to beat it; no way to fake it.

>It's natural to explain an idea in terms of what you already have in your head. Concepts are piled on top of each other; this idea is taught in terms of that idea, and that idea is taught in terms of another idea, which comes from count- ing, which can be so different for different people!

>I often think about that, especially when I'm teaching some esoteric technique such as integrat- ing Bessel functions. When I see equations, I see the letters in colors-I don't know why. As I'm talking, I see vague pictures of Bessel func- tions from Jahnke and Emde's book, with light- tan j's, slightly violet-bluish n's, and dark brown x's flying around. And I wonder what the hell it must look like to the students.

Thanks for sharing it, I can now share it to my siblings. A silver lining that despite the cancer she could leave relatively peacefully.

The article & some comments do make me wonder: my mother refused any medication, including any painkillers, for 6 weeks after terminal diagnosis. Only on her last day, when breathing got painful did she accept a fentanyl patch to be administered. She lost her consciousness a few hours later, and less than a day later her breath. I wonder if it was dosed for that (as some form of mercy)

>I do not intend to calibrate the camera’s extrinsics or intrinsics for now.

Sensible choice, although I suggest it's good in the long run to do at early stage in your setup, especially if you intend to collect data for policy learning.

Debugging trained policies for visual manipulation task can be a headache and having as much context on variables that can change is a good practice.

My previous setup was in Japan, a earthquake prone place and I wasted some time after realizing the camera got misaligned due to earthquake. A simple solution is just to place an Aruco marker on the table that tracks the relative extrinsic position of camera, and add it as metadata to collected teleoperation dataset.

If your task is for example, to pilot a preset route with stable condition and very low surprise, you will fall for the "getting too comfortable" trap and we tend to start to get lazy(or efficient) and offload the mental effort and skills atrophy. A common workaround to this is to have regular training(deliberate practice) that introduce the "tricky" situation to keep the skill up. Problem ofc arises when people don't keep this up.

This can be seen in the diagnostic performance differences between junior and senior doctors, not always in the favor to the senior [3]. If you add a layer of automation but the insight gathered by working on that layer is great (and falls off) then deliberate practice start to become a requirement

Not that central bank won't be able to do the same, but it would have to follow laws set by the government rather than law+whatever the card companies decide to.
