Infinite Jest update: OMG I READ IT!

Took me almost three months. Footnotes and all. But finally I'm done. Absorbed. Chewed. Ingested it.

Mentally, I feel so full, like I'd eaten a whole turkey. Bones and feathers included.

Emotionally, I feel satisfied, proud, disgusting, nauseous, sleepy, confused, bored and overwhelmed.

So, looking at this and considering how evolution is also a story of symbiotic relationships:

Has anyone considered the brain to be a next-gen, space-age mycelium yet?

@SpringStreetNYC Qualitätsmeme, halt

Jupp!

Ich weiß leider nicht mehr, wer es damals gemacht hatte, aber auf jeden Fall um 2022 herum auf Reddit gefunden.

Zuerst hab ich den Zusammenhang gar nicht gerafft. Und als es dann klick gemacht hat, kam sofort die Erinnerung zurück.

Ich, Kind, mit Mutter in der Oberurseler Vorstadt im Schuhladen stehend. Gerade eben mit dem linken Schuh durch den Laden stolziert, Daumentest bestanden und dann die Frage: "Die in hell?"

Als wäre es gestern gewesen!?

LLMs are so clearly (post-)trained in English.

Trying to use them for German emails is incredibly cringe - I try again and again and can't use a single sentence.

Everything reads like it was written by a guy over 50 who types with two fingers and takes offence if you don't address him with his doctor title.

It's as if the only German contributor to post-training was Olaf Scholz.

@DominiqueCAPaul Oh! I wanna see examples now! 🤪

is youtube kinda unwatchable now? wtf happened?

I fixed my YouTube feed by (rigorously) using the "Do not recommend videos from this channel" for a month.

Just a heads-up: It felt like strangling a beast. For the first rounds your feed cleans up quickly but then their algorithm fights back with even shittier, top-of-bell-curve slop that you had initially.

You gotta keep blocking channels until suddenly the feed stays clean and tight.

Good luck! You'll need it but it's worth it.

we’re using local apple intelligence models a lot these days in our product for a lot of little things & they work incredibly well, especially for personalization & copy.

you can cache these so you create a pretty lovely little experience in subtle places where the app feels tailored than just one to many (all for free!).

it’ll feel cool as hell when they get even smarter.

@signulll Loved futzing around with Apple's 3B Foundation Model!

YO! I just completed my fourth @karpathy autoresearch-inspired project called "Beeline". It's sort of a prototype for "GPS without GPS" for UAVs.

Claude and I iterated through 81 ideas and found a small neural thingy that can be trained to recall 96% of locations, given satellite images to train on and then a camera frame to remember latitude and longitude for.

Basically:
1. Train: Here are all tiles and their latitude/longitude, remember them
2. Infer: Here's a live frame from my camera. Where am I?

Claude for experiment design and implementation, me for research cybernetics.

My favorite part is that the resulting artifact (the .onnx model that represents the memory of spot and lat/lon) is intentionally custom-built for the defined geo-fence and thus the research harness had to embrace overfitting for this one specific case as a feature, not a bug.

The biggest suprise was that in order to break-through the 75-long experiment plateau, I had to fix the harness, not the loop.

And of course, this is a personal research project, so a bunch of limits apply. Such as training only happened on day-time pictures and the training set is bound to a geo-fence and more.

But hey! It's invented and built completely from scratch, so no dependencies on domain-libraries which means it's all GPL-licensed, too!

If you're interested, check it out here! :D

@karpathy PS: To make this a bit more understandable. Basically we started with all dots red 🔴, created a training set, tried 81 different memorization techniques and landed on all dots green 🟢

One downward photo in, (lat, lon, confidence) out — the map is the weights, one city in 3.1 MB. Found by an autonomous loop of coding agents in 81 experiments for $364.↗ alexisrondeau.me

Proud to announce: I'm 65% through Infinite Jest. And still reading. And enjoying it a lot.

What impresses me the most is that reading Infinite Jest has created an urge in me to read a bunch of other books in parallel. This has not happened to me before. I'm confused.

So that means I'm also actively reading DFW's bio by D.T. Max, "The Emperor of Gladness" by Ocean Vuong and "Wahrheit ist die Erfindung des Lügners" by H.v. Foerster.

Much to say, maybe in a series of tweets in the coming week. I'll post those below as they roll in.

Infinite Jest has the highest (fiction) prose to highlights ratio in my Kindle library.

Surprise 1: Most of those highlights are single sentences or shorter.

Surprise 2: Most of them really mean I want to capture the feeling more than any presented facts or ideas.

Oh, interesting. As you probably have noticed, reading Infinite Jest has given me an itch to write a bit more, too. See also: Overweight sports fans, cargo culture, usw.

Nothing of note actually happens in the first half of the book. But by page 500 I deeply understand how everyone and the world got "here."

Remarkable.

Critic: After reading all of Pratchett's discworld last year, I feel spoiled.

I find Infinite Jest's character names ("Incandenza", "Schritt", "Joelle", "Steeply") the weakest link in the writing.

Another thought:

If you love reading, you will absolutely adore Infinite Jest.

If you love stories, you will completely hate every page.

dunking on ppl who have tried extraordinary things & then had a set back is lame.

Not sure if I've ever tried extraordinary-extraordinary things but I can say that nothing could have prepared me for the shockwaves of my mom passing.

So, I believe that there are these significant and unexpected setbacks in life from which recovering is in itself an extraordinary feat.

Continued thoughts/impressions and the like:

I've re-read R.A.W. & R.S.'s "Illumiatus!" trilogy five or six times over the years.

So reading IJ feels like finding a distant cousin in spirit. They're similarly encyclopedic (I've collected the full list of band names from the Lake Totenkopf festival of anyone is interested!), they both switch between POVs (present/past, inner/outer monologues, etc.), they both contain full vaguely related storylines where some cross paths only on the final pages, they both take place in imagined, remembered, hallucinated and "real" situations, they both revolve around odd public and secret organizations, they both contain oddly gratuitous "Mord und Totschlag" and more...

In my opinion, one of the biggest differences I found was that the trilogy goes into action right away while I feel like I've spent 500 pages in IJ carefully observing the status quo and getting a deep, deep, DEEP brief into "But and this is how we got here..." (BTW I love DFW's sentences starting with "But so/and...")

I'm at 65%, discounting the appendix, and I would say, the first actual action started exactly at the 50% mark. The unfolding of the Eschaton game chaos felt like a "OMG finally something is actually happening!".

And, well, if manifesting the "Eschaton" on a tennis court is not a nod to the trilogy, I don't know what is.

Now, one of the ways, that IJ is gaining a very special place in my heart is that I've never read an author with DFW's level of "Aufnahmevermögen", meaning his ability to observe and verbalize all kinds of inner thoughts that, once he's written them down, made me think "Oh, shit. I've had that exact thought or feeling dozens of times but didn't even notice them!"

Currently it's those incredibly microscopic bylines that have kept me coming back most. I'll find and share some examples later.
