At first I was frustrated by this comment, having a fair amount of Lisp experience failing to grok the examples. In less than one minute I was able to locate, download and install the latest Racket and was in a REPL. There really are no excuses.
This was a wild ride. I'm torn on whether this feels like the Reader is bloated/polluted or whether this is the coolest numerical parser I've ever used. You can really do a lot to coerce the these numbers just by inserting an {o,s,e,i,b,#} into the number, with different semantics depending on the position of the character.
Somewhat overwhelming, I can only hope there's some elegance underlying it all...
There are books that I read every decade or so, and there is always new insight. Sometimes I will identify with an older character and see the entire story through their eyes.
Often times an interesting novel will prompt me to study the cultural context independently.
There was still tremendous value in exposing myself to Dostoyevsky as a teenager. I have observed myself make the same mistakes as his characters, blinded in the moment by emotion. He had so much insight into human nature - but even if forewarning doesn't prevent us from folly, it can highlight a path to acceptance, repentance or redemption that otherwise may take a lifetime of self-reflection.
I don't mean that in a religious context, if that matters.
I for one am striving for clarity and couldn't care less about being confused with AI.
However I've only ever used regular dashes. How do you type an em-dash? Is it OS specific? I've taken to using Emacs insert-char with a list of frequently used ones in my scratch buffer. My memory for Unicode is unreliable.
Keyboard layout specific. Macs with their default English layout use “option-shift-dash” which is really easy to remember (and relatively discoverable, as such things go) which is why using proper m-dashes (not just double-dashes) used to be a strong indicator a poster was using a Mac, before LLMs took the character over.
On iOS you type it by pressing dash and holding until alternative options come up, same way you type e.g. accented characters.
Macs have two possible ways. If you have key repeat enabled, option+shift+dash. Some newer Mac users may have the mode on where holding a key pops up an iOS-style bubble of alternate options, in which case they will just hold hyphen.
In emacs, c-x 8 RET prompts you for unicode character names (or hex) so for rare use you can just spell it out. There's also C-x 8 _ m for em dash and C-x 8 _ n for en dash. (Hit c-x 8 c-h to get a full list of those bindings, like any normal secondary map - they're about as idiosyncratic as the XCompose bindings, but you might find some of them "stick" in your head better (I personally like "C-x 8 1 / 2" better than "Compose 1 2" even if it's a lot more typing...)
Ooh, thanks! I blindly type c-x 8 RET, then finding myself stumbling through 9 different entries for Phi, but I hadn't explored the prefixes. I just realized I could create a custom which-key entry-point with my favorites in a prefix.
Also just learned about compose key apparently, and I noticed that I can program this split keyboard I'm using to turn that into a chord, anywhere!
Then an LLM told me that I can 3D print my own custom keyboard with 32 programmable layers. Everything is an infinite rabbit hole these days, how wild.
Macs have a native way to do dashes: option- hyphen for en-dash and option shift hyphen for em-dash. On Windows there are some application-specific ways that make sense, e.g. in Office, but outside that you’re on your own and have to use the “hold alt and type the character codes” method! Or charmap.
This was a lot of fun to explore. I find that naturally I want to click through the animations and observe them for a while before delving into the steps and reading the blurb. It's a bit like skimming around a textbook's headings & figures before reading the chapter, it builds motivation and interest.
One simply change to improve the experience is to keep the Next/Back at fixed locations. The animations and transitions are beautiful, and looking away to chase the moving buttons causes me to drop the visual context.
As a workaround I set the height of .tour-body to 900px and the the whole thing became so much more immersive, like the old planetariums.
Even if these are contrived examples this is one of those things that could become completely ubiquitous as a cheap solution to problems that only seem obvious in hindsight.
Either that or we'll never see this tech again, it feels like there's no middle ground. I wonder how the cost scales up for mass production
There was another rule you did not know seemingly. Please don't use HN primarily for promotion. It's ok to post your own stuff part of the time, but the primary use of the site should be for curiosity.[1]
This would make for a good topic on a short-form pop-science YouTube channel. (take your pick)
The article is interesting but it's difficult for me to really picture the implications of the article. Actually after reading it I get the feeling that what I was visualizing is entirely contrary to what they are trying to convey to me.
