There's your one line change.

fritzo··on In Denmark, the spread of solar panels has become a divisive issue
If it's a poor location for photovoltaics, it's exactly as a poor for photosynthesis
fritzo··on LinkedIn uses 2.4 GB RAM across two tabs
Sorry for my ignorance, but what exactly is the distinction between hn and social media? Is it the personalization that distinguishes the two? Does "social" mean "feed depends on graph neighborhood"? So collaborative filtering + ranking algorithms + moderation is not social media until you add graph neighborhoods?
fritzo··on A laser-based process that enables adhesive-free paper packaging
I've also seen a glue-less paper binding trick where two pieces of paper are finely crimped together with some high pressure tool in alternating v^v^v^ patterns, actually making tiny tears in the paper. Does anyone know what kind of tool does that?
fritzo··on Day 1 of ARC-AGI-3
ELI5 what is a harness?

EDIT from https://arcprize.org/media/ARC_AGI_3_Technical_Report.pdf:

> We seek to fight two forms of overfitting that would muddy public sensefinding:

> Task-specific overfitting. This includes any agent that is created with knowledge of public ARC-AGI-3 environments, subsequently being evaluated on the same environments. It could be either directly trained on these environments, or using a harness that is handcrafted or specifically configured by someone with knowledge of the public environments.

fritzo··on AI users whose lives were wrecked by delusion
Sounds like her first thought was, "I'm talking to a manic guy, and I can use him to make money"
fritzo··on Government agencies buy commercial data about Americans in bulk
Wait, is 474 a number or a proper noun?
fritzo··on So where are all the AI apps?
They're private, that's the beauty. Code is so cheap now, we can ween ourselves off massive dependency chains.

200 years ago text was much more expensive, and more people memorized sayings and poems and quotations. Now text is cheap, and we rarely quote.

fritzo··on Reports of code's death are greatly exaggerated
Those business goals will soon realize they need more electricity. More brains will be devoted to power generation.

The same could be asked about people. The answer is social intelligence.
fritzo··on Chest Fridge (2009)
By that logic, best fridge is no fridge at all ;)
fritzo··on The Los Angeles Aqueduct Is Wild
Thank you, I was so confused by the obvious clickbait! I love Grady's videos, but yikes.
fritzo··on The math that explains why bell curves are everywhere
> optimum properties for estimating a posterior distribution

Circular reasoning: that's true only if the posterior is normal, or if your "optimal" is defined by second moments. In infinite variance cases, the best estimator can be median or an alpha moment for alpha < 2, but yikes the math is much more difficult.

fritzo··on The math that explains why bell curves are everywhere
Heavy tails are everywhere. Normal distributions have absurdly light tails. Levy alpha stable distributions have power law tails. Power law tails are everywhere.

Some things with heavy tails:

  token occurrences
  comment thread upvotes
  startup IPOs
  social follower counts
  network latency
  github stars
  git diffs
  power station size
  weather events
fritzo··on The math that explains why bell curves are everywhere
Right. And the CLT is not actually limited to normal distributions. Both of the distribution families I mentioned are central limit theorems. The CLT we first see in school regards means of finite variance distributions, where the finite variance assumption is made because it makes the math easier.

https://en.wikipedia.org/wiki/Central_limit_theorem#The_gene...

fritzo··on The math that explains why bell curves are everywhere
Hot take: bell curves are everywhere exactly because the math is simple.

The causal chain is: the math is simple -> teachers teach simple things -> students learn what they're taught -> we see the world in terms of concepts we've learned.

The central limit theorem generalizes beyond simple math to hard math: Levy alpha stable distributions when variance is not finite, the Fisher-Tippett-Gnedenko theorem and Gumbel/Fréchet/Weibull distributions regarding extreme values. Those curves are also everwhere, but we don't see them because we weren't taught them because the math is tough.

fritzo··on Epiplexity: Rethinking Information for Computationally Bounded Intelligence
Is AlphaZero actually machine learning, if there is no data, or the data is entirely synthetic? If so, we must admit that deterministic automated proof search is machine learning. Shannon's and Kolmogorov's accounts of information leave us stranded. Finzi et al. propose to resolve our confusion.
fritzo··on Show HN: Horizon – GPU-accelerated infinite-canvas terminal in Rust
I was hoping this would be an infinite length terminal view, like the opening backstory in Star Wars
fritzo··on Polymarket gamblers threaten to kill me over Iran missile story
Just checking :) Didn't want to confuse two totally different equally compelling reasons to ban prediction markets
fritzo··on Lies I was told about collaborative editing, Part 2: Why we don't use Yjs
Agreed. In my limited experience, conflict resolution rules are very domain specific, whereas CTDTs encourage a lazy attitude that "if it's associative and commutative it must be correct".
fritzo··on Polymarket gamblers threaten to kill me over Iran missile story
We're not talking about gambling-as-addiction. We're talking about gambling as big players paying participants to throw fights, paying referees to call shots, and the players are the real world and the referees are journalists.
fritzo··on No, it doesn't cost Anthropic $5k per Claude Code user
I'm not accountant, but I would expect Pizza Hut's accounting is significantly more complex than Anthopic's. 50+ year old global franchise with physical supply chain partnerships vs an upstart SAAS company?
fritzo··on Bluesky CEO Jay Graber is stepping down
Good point. For sake of argument, how about this stratification of privacy levels:

twitter/x/bluesky - a big tech company owns your data

mastodon - a grassroots community organization owns your data

zulip - someone you've met personally owns the data

your blog - you own the data

(and yes these are a bit of a category error, but to achieve privacy maybe we should broaden the category and sacrifice reach)

fritzo··on Bluesky CEO Jay Graber is stepping down
The community has voted for convenience over privacy, and twitter and bluesky have won over mastodon. You're right, but people don't actually care about privacy
fritzo··on Grammarly is offering ‘expert’ AI reviews from famous dead and living writers
This is great!

One lesson they might draw from the negative press is to offer a more open-ended interface, like ChatGPT, where for years people have already been asking "Pretend you are X and review my writing". This interface design pattern gives the press nowhere to point their angry fingers

fritzo··on A ternary plot of citrus geneology
Inheritance is astonishingly more complex than trees, e.g.

Wong et al. (2024) "A general and efficient representation of ancestral recombination graphs" https://doi.org/10.1093/genetics/iyae100

fritzo··on Does that use a lot of energy?
How does it make sense to compare renewable vs non-renewable energy sources?

Where does that electric car's energy come from?

Suppose the electric car's energy is solar. Then driving the electric car consumes zero barrels of oil, and so is infinitely more renewable than the petrol car. Or how efficient is the electric car at capturing available energy? Maybe the petrol car is 20% efficient at capturing available oil reserve energy. But the electric car is like 1e-30% efficient at capturing available solar output. Incomparable.

fritzo··on I'm losing the SEO battle for my own open source project
Don't forget the SourceForge rug pull, when the once definitive central source of truth was bought out and became a venue for malware
fritzo··on Cognitive Debt: When Velocity Exceeds Comprehension
I recently spent 1.5 weeks fixing a bug I introduced 20 years ago. Can confirm, I have no idea what I was thinking back then.

Barendregt & Manzonetto's 2022 "A lambda calculus satellite" has a whole chapter on the S fragment, for those interested
