I started wearing a bath robe belt as a tail and my brain quickly starts telling me I am wearing it when I am not. I also had a phantom watch ⌚ on for a week after losing it.

Did HN start allowing emojis or did that one slip through the cracks because it pre-dates the inclusion of Japanese emojis?

Testing ⌚

https://emojipedia.org/watch says it's from 1993 Unicode 1.1

But the other emojis from that group seem to mostly not work.

Marshal McLuhan's book Understanding Media had the full title "Understanding media: the extensions of man." And he had a chapter about the automobile. If you've ever had the chilling experience of a skid, the terrifying adrenaline surge during that second where it is clear the car is no longer under your control, you know the dude was onto something. The car is an extension of our bodies. An extra body part.

I have pressed an imaginary "brake pedal" with my foot many times when travelling as a passenger in vehicles with someone else driving, just because i was watching the traffic and sensed the need to slow down. Another instancee -- In my country growing up we didnt always have "blinkers" on our vehicles (light motorbikes, scooters, bicycles) -- so it was common to use "hand signals" to indicate your intention to turn…

My big question is how you get input to work. Could you just put a patch on some unimportant bit of skin, let's say a 4"x4" area on your back, and use that patch to deliver tactile information from the thumb in some systematic way? Would it eventually start feeling like it was coming from the thumb?

Similar here. For a very long time, I thought that being good at something was knowing the system and rules, and applying them consciously every time. It's funny because I legit thought that that's what I was doing while playing video games or doing martial arts (the only things I was reasonably good at for quite awhile). It turns out the learning and doing processes are both deeply subconscious; very little goes on…

There is a new shift in the understanding of coaching in sports called the Constraints-Led Approach (CLA). It's both super nerdy and practical (i.e., based on practitioners' empiric experience). Basically, it sees the body as a complex system of organs/tissues/cells that tries to solve movement problem under the pressure of different constraints. In a simple words, coaching then is the art of creating/manipulating co…

Yes constraints are great. My piano teacher would basically just repeat to me like mantra:

- was it legato?

- were you playing free from tension?

- was your tone even?

- were you in time?

Very rarely would he actually ever tell me anything. And whenever I'd ask for more or feedback he'd just loop back to the questions and ask if I was actually listening to myself play. It was a very frustrating start but eventually it all clicked what he was doing was teaching me to understand my own constraints and then also understand what are the outcomes I am aiming to achieve - if I can't hear how even my own touch is how will I ever play evenly.

Was the most valuable coaching I ever got and was probably life changing for me in terms of levelling up my ability to learn new things.

Prior to meeting him I held the belief there was a "perfect way to play" the piano and would occasionally peruse books and videos on the subject. Of course, as my teacher was keen to point out, no body is the same so how can two anatomically different pianists play with the same technique?

If you have small hands so much of the repertoire will be different vs if you have rach hands

Yes - I'm learning singing at the moment and just the other day the teacher fed back - don't try to over-conceptualise what you're doing. Just do it, focus on the outcome, stay relaxed and the body will figure it out. I've been through enough learning cycles to appreciate this but this was a real hurdle for me when I was young because my default was to rely on systems and rules. Ironically as a swimmer my biggest bre…

On rules and applying them I am always reminded of this quote from Bruce Lee:

"Before I learned the art, a punch was just a punch, and a kick, just a kick. After I learned the art, a punch was no longer a punch, a kick, no longer a kick. Now that I understand the art, a punch is just a punch and a kick is just a kick."

As applicable to fighting as it is programming. You will see it in high level sports - athletes will do all kinds of unorthodox things from weird positions to eke out a result, because the result is all that matters.

Emoji Looks like a wingding to me, let’s just have it maybe.

It's an emoji. On my machine it renders in color and in the same style as other emojis. There are a number of emojis that use pre-existing Unicode glyphs. If I remember correctly there are control characters to opt-in/opt-out of emoji style presentation for these characters.

I can't believe this place bans cleverness and Unicode. Oh wait this is a startup farm

There's a certain type of people that considers emoji unserious and distracting and thinks they are detrimental to nuanced and intelligent conversation.

Of course it doesn't follow that a lack of emojis is sufficient to create nuanced and intelligent conversation but said type of people also believes HN is tangibly different from Reddit.

Today was June 2, 2024. Unicode watch still works.

I once saw a documentary on a haptic compass, built from some rumble packs. It allowed people to improve their way-finding skills, and if I recall correctly, people accustomed to the idea of having this extra sense after about a week or so. I can’t easily find the original research (somewhere in the 1990s), but several hackers and artists have rebuilt or rediscovered the idea. See for example https://blinry.org/compa…

Would be cool to build one into a baseball hat.

Or even put an array of car parking proximity sensors into that hat. https://www.kit.edu/kit/english/pi_2016_003_feeling-spaces-w...
