levocardia··on U.S. science is in chaos
...which is why there are no emerging far-right-populist political movements in welfare-heavy societies like the UK, France, and Germany, right?
levocardia··on Has AI already killed self-help nonfiction books?
Conversely: the self-help nonfiction book existed because it was the only practical way to monetize "good advice" or "good ideas" at scale. Now you can do a podcast or a youtube series and try to make money from advertising/affiliates/etc, but for a very long time, "buy my book" was the only game in town
levocardia··on Confidential submission of draft S-1 to the SEC
So are you short the market?
levocardia··on How to convert between wealth and income tax
There is a footnote discussing this point; he uses 5% as the risk-free rate.
levocardia··on Pope Leo XIV’s first encyclical Magnifica humanitas to be published May 25
The intentional parallels are hard to miss:

- Pope Leo XIII wrote Rerum Novarum; current Pope Leo XIV chose his name as an explicit gesture to his nominative predecessor

- This encyclical is a return to the earlier tradition of latin names (Magnifica Humanitas) for encyclicals, as opposed to many of Pope Francis' which used Italian (Laudato si')

- The official date it was signed was 135 years to the day since Rerum Novarum

- The Pope is personally appearing and speaking at the presentation; usually these encyclicals are just released at a small press conference without the Pope himself being there

Rerum Novarum intentionally tracked a third path, rejecting both socialism and laissez faire capitalism at the end of the 19th century. Gesturing so overtly towards it suggests that this new encyclical will also try to establish a "third way," grounded (as the title suggests) in human dignity.

Leo XIV has not published any encyclicals yet; this will be his first, and an extremely ambitious one at that. I also am very eager to read it.

levocardia··on The AI zombification of universities
>As it turned out, the online version of MIT is not a substitute for the actual thing.

More precisely, the people motivated enough to actually do the online MIT version were often already on a high-performance trajectory, and for the people who were not, few people took the online credential seriously, despite whatever skills they acquired.

levocardia··on Princeton mandates proctoring for in-person exams, upending 133 year precedent
Not even prestigious ones. The school needs to sound like it has strong penalties against cheating, so there are really strict-sounding policies ("zero in the course"). But also, so many students cheat that actually enforcing these policies uniformly would hurt your graduation stats, make unhappy customers (students + parents), and hurt your revenue if you actually expel them. So the equilibrium is that the burden of reporting cheating is foisted upon professors, and it is understood -- though never explicitly communicated -- that academic integrity proceedings will be a huge administrative pain for you, the professor, and it is in your interest not to initiate them.

The outcome is predictable: unless there is a scandal of massive proportions, the issues just..."go away" on their own. With some discretion for the professor to either just look the other way, or ding the student enough to feel vindicated, but not so much as to actually hurt the university's interests.

levocardia··on YC's Biggest Scandals
Probably the worry that the jump from "we defend against slaughterbots" to "we built a better slaughterbot" is just around the corner
levocardia··on Pulitzer Prize Winners 2026
Who do you think would be deserving of an outside-the-window Pulitzer?
levocardia··on US healthcare marketplaces shared citizenship and race data with ad tech giants
The actual "sharing" was using the Meta pixel and TikTok's equivalent, presumably so the healthcare exchanges could do retargeting or similarity-based marketing to get people to sign up for health care coverage. Which, narrowly, seems like a reasonable thing to do. But of course using the pixel automatically "shares" the data with Meta/ByteDance/whoever, and they get to use it for whatever nefarious purpose they want.
levocardia··on Removable batteries in smartphones will be mandatory in the EU starting in 2027
Would have been even more classic EU to not add the exception and have all Europeans stuck with a slower, bulkier, and more expensive "EU edition" of a phone.
levocardia··on First Tesla Semi Rolls Off High-Volume Production Line
(which electric cars and trucks also reduce, because of regenerative braking)
levocardia··on Ti-84 Evo
Agreed, it's insane to me that in an era of Google Colab (et al) schools still require students to shell out >$100 for one of these. I'm sure there is some backroom arrangement with schools of some kind.
levocardia··on Opus 4.7 knows the real Kelsey
I noticed this phenomenon a few months ago. I often "chat" with blog post excerpts that use language or references I don't understand, and while I'm waiting for the model to finish thinking, I like to read the reasoning traces. Spontaneously, without doing a web search, and without me saying who the author was or even mentioning that I wanted to know who it was, the model would drop an off-hand mention to the identify the blog post author in its reasoning trace. I then started doing "pop quiz" questions to see if the model could recognize a paragraph or two from a blog post (always a very recent one, often the very same day it was published) and it would nail the author almost every single time. Works for a very wide range of bloggers even when they are writing "off their normal beat."
levocardia··on HERMES.md: Anthropic bug causes $200 extra charge, refuses refund
Goes to show how much consumer surplus you're getting for that $200/mo subscription...
levocardia··on Talkie: a 13B vintage language model from 1930
Indeed, I found this part extremely interesting. The more general vision of "testing a vintage model on something invented after its training data ended" seems like quite a strong test of "true cognition" (or training data contamination, if you haven't stopped up all the leakage...)
levocardia··on Why has there been so little progress on Alzheimer's disease?
Elaborating a bit - brain is hard to study since you can't easily take a biopsy of it (from a living person at least), and various brain scans are not great at identifying the stuff we care about.

The slow acting nature of it means also you have to wait a long time to see results of clinical trials; also because early stages are easy to miss that also means you are stuck studying people who are already pretty senile and thus might be beyond the point where you can make a big difference.

Ruxandra has a nice piece, focused on cancer, but the reasoning is basically the same here: biology is just really hard. Sometimes we get lucky but in general it's a long, slow slog.

levocardia··on John Ternus to become Apple CEO
So you're looking forward to a $2000 iPhone 18e?
levocardia··on ggsql: A Grammar of Graphics for SQL
I share your pain. You might enjoy Plotnine for python, helps ease the pain. The only bad thing about ggplot is that once you learn it you start to hate every other plotting system. Iteration is so fast, and it is so easy to go from scrappy EDA plot to publication-quality plotting, it just blows everything else out of the water.
levocardia··on Measuring Claude 4.7's tokenizer costs
Depends a lot on the task demands. "Got 95% of the way to designing a successful drug" and "Got 100% of the way" is a huge difference in terms of value, and that small bump in intelligence would justify a few orders of magnitude more in cost.
levocardia··on Filing the corners off my MacBooks
Honestly that was the cherry on top for me -- the employee confident enough to just decide "this is my work computer, I need it to do work, I can't do work with my hands being irritated, so I will sand down the edge." Pure gold.
levocardia··on Many African families spend fortunes burying their dead
>Kinship societies are actively hostile to economic growth, because economic growth undermines the basis of kinship: that is why kinship societies demand constant, visible sacrifices of wealth—funerals being the most spectacular—that make it extraordinarily difficult for any individual to accumulate capital, reinvest their assets, and pull ahead. The funeral is a window into a system of wealth destruction that serves, above all else, to keep people poor

This reasoning is flawed. Consumer spending is not "wealth destruction" -- who makes the fantasy coffins? Who prints the banners? Local businesses!

Ghana is sitting at a 5.6% GDP growth rate; for reference developmental success India is at 6.5%. Ghana's GDP in 2000 was $5B, today it's $82.B. Its per-capita GDP has more than doubled in the same time period.

levocardia··on Reverse engineering Gemini's SynthID detection
Sure there is a solution, you are just looking at it the wrong way. Make non-AI images provably unaltered with signed keys from the device (e.g. the camera) that took it.
levocardia··on Things I learned from Reddit fashion
You can tell the author went deep into reddit because they fell for the wool meme. Sorry but synthetics (for anything active) are far better: lighter, warmer, better at dealing with moisture.

One pattern I noticed that was missing: the classic reddit experience of saying "I'd like a new shoulder season jacket, and I want to spend less than $100" and having some know-it-all try to convince you that what you really need is an ultra-nano-pore down puffer made by a blind Italian artisan that costs $950, and that anything else is Wal-Mart-tier garbage.

levocardia··on Who is Satoshi Nakamoto? My quest to unmask Bitcoin's creator
Interesting: my Occam's Razor test is "$100B sitting around untouched, how can that be?" Well, simplest answer is that satoshi is dead.
levocardia··on Who is Satoshi Nakamoto? My quest to unmask Bitcoin's creator
Yeah this one seems absolutely insane, how many Satoshi Nakamotos are there in the world? It's very plausible to see the name on a mailbox (or meet the person) and think "that'd be a cool handle." And it's so wildly improbable that someone else would make up exactly the name of a neighbor of one of a small clique of obscure internet cypherpunks. It's not like the name was "John Smith" or anything.

But I don't know how to square that with the "Finney was running a marathon while satoshi sent emails" claim.

levocardia··on Muse Spark: Scaling towards personal superintelligence
Anthropic had their mythos post (and model) basically ready a few weeks ago, as evidenced by the blog content leaks. Also I highly doubt they just threw together a 250-page PDF model card in a "rush."
levocardia··on Muse Spark: Scaling towards personal superintelligence
Funny contrast with Anthropic. Ant does a "hero run," gets a model much more powerful than they expect. Meta does a hero run, gets a model much more mediocre than they expect. Read into this what you will, I guess?

CSS with a linear gradient background would be even smaller :)
