peterlk··on Ask HN: Why isn't email a government service?
You're right, I didn't know that. Thanks!

In the US, this could be a municipal service (my.name@themunicipality.emailservice.mystate.gov), and then we treat everyone in a geography as an organization. This feels a bit more likely to represent an "organization", especially for smaller municipalities. I would expect service availability and quality to vary widely between different municipalities - similarly to how parks, bike lanes, and other infrastructure quality vary widely between municipalities.

peterlk··on Ask HN: Why isn't email a government service?
The postal service is a federal service. If email offerings were, say, a municipal service, it seems like the Feds would have a much harder time regulating it. The federal government in the US can certainly put pressure on municipalities, but it wouldn't be compulsory - for example, university emails don't need to be used as a primary email except for specific, university-related circumstances.

This argument could easily be extended to private businesses. The government has the capability of putting pressure on private entities to compel them to treat email in certain ways. The rule of law prevents such things, and I don't really want to start a thread about how the current administration has no regard for the rule of law.

Furthermore, not everywhere is the US. Why hasn't Germany done this? Or Australia? Or Singapore?

peterlk··on A.I. researchers are negotiating $250M pay packages
There is a group of wealthy individuals who have bought in to the idea that the singularity (AIs improving themselves faster than humans can) is months away. Whoever gets there first will get compound growth first, and no one will be able to catch up.

If you do not believe this narrative, then your .com era comment is a pretty good analysis.

peterlk··on The hype is the product
I don't think we need to redefine reasoning. Here's the definition of "reason" (the verb): "think, understand, and form judgments by a process of logic"

If Claude 4 provides a detailed, logical breakdown in its "reasoning" (yeah, that usage is overloaded), then we could say that there was logical inference involved. "But wait!", I already hear someone saying, "That token output is just the result of yet another stochastic process, and isn't directing the AI in a deterministic, logical way, and thus it is not actually using logic; it's just making something that looks convincingly like logic, but is actually a hallucination of some stochastic process". And I think this is a good point, but I find it difficult to convince myself that what humans are doing is so different that we cannot use the word "reasoning".

As a sidenote, I am _very_ tired of the semantic quagmire that is the current AI industry, and I would really appreciate a rigorous guide to all these definitions.

peterlk··on The hype is the product
A dismissive “no” is not a helpful addition to this discussion. The truth is much more interesting and subtle than “no”. Directed stochastic processes that reach a correct conclusion of novel logic problems more often than chance means that something interesting is happening, and it’s sensible to call that process “reasoning”. Does it mean that we’ve reached AGI? No. Does it mean the process reflects exactly what humans do? No. But dismissing “reasoning” out of hand also dismisses genuinely interesting phenomena.
peterlk··on Daily Notes Considered Harmful
I am never sure which notes I am going to reference again. Most of my daily notes go unread forever. But occasionally, that seemingly trivial thing that I jotted down in a meeting turns out to be _very_ important. I have AI assistants that take notes for me too, but somehow I can’t stop taking notes in meetings - and occasionally this has saved me (note taker bugged out).

Daily notes are also where I do a lot of scratch pad thinking, and occasionally those come in handy as well.

peterlk··on Supreme Court's ruling practically wipes out free speech for sex writing online
Hijacking this comment because it seems to be the most recent. I’d love to start a private email thread with you if you’re willing to do so.

After the previous election, I felt wildly out of touch, and I’ve been trying to find people who I can talk to who might be able to help me improve understanding of my (metaphorical) neighbors. I suspect that our beliefs will be quite different, but I appreciate your willingness to provide long-form, respectful responses to so many comments here.

peterlk··on Could a Paper Plane Thrown from the ISS Survive the Flight?
Answer: it would most likely burn up

Original paper: https://www.sciencedirect.com/science/article/pii/S009457652...

peterlk··on So you wanna build an aging company
Creating stem cells from blood samples is a well-established industry practice now. I don’t think limiting embryonic stem cells research is significantly hindering stem cells research, is it?
peterlk··on Business books are entertainment, not strategic tools
I think there are maybe 5 business books out there. I’m not sure how exactly I’d define the 5 different business books, but I think of you read 10-15 business books you’ve pretty much read them all. After a while, they all start boiling down to the same few points with differences in narrative content. If I were to take an unconsidered stab at a few of them: hard work + luck is about the closest formula anyone has found for success if applied over long time periods; you have to be disagreeable and believe in yourself, but not so disagreeable that you can’t get along with anyone; people are important, and treating them well leads to better businesses (over long time periods); sometimes you get dealt a bad hand.
peterlk··on Where do scientists think this is all going?
I sent outputs to experts (friends )in those fields who provided me with some specific topic that is common to their niche. In general their feedback all aligned with: “yeah, this is pretty decent, but anyone who was a professional would know about <some hole in the output>”.
peterlk··on Where Do Scientists Think This Is All Going?
I think you’re fixating on the specific example that I cited rather than imagining the possibilities of the technology. We now have: zero-shot classification capabilities for basically any task, performance that is consistent enough for independent LLMs to collaboratively produce robust long-form responses, the ability to produce almost any web UI element on command with functional hookups to an API. And that’s just LLMs. SAM2 has good performance for realtime object detection in video.

Perhaps a more fruitful line of inquiry could be: what would the internet look like if every web application implemented support for A2A?

peterlk··on Where do scientists think this is all going?
I am surprised at the negativity and cynicism in this thread. I suppose the pendulum of hype has high amplitude.

Just because AI isn’t going to be some kind of all-knowing sci-fi AGI doesn’t make it all a sham. The recent research models are miracles of technology - we can now get in ~15 minutes an undergraduate-level report (that would take an undergrad days or weeks) on almost any topic. That’s incredible! The capability of an AI model is approximately junior level in the fields I’ve tested it in (programming, law, philosophy, neuroscience). If you’d don’t see any possible uses for the technology, keep thinking about it.

peterlk··on Tailscale has raised $160M
I think we are saying slightly different things. COGS are composed of many smaller capital allocations. According to this untested, pet thesis, putting on a report that $250M was spent on capex is just fine; but if you go to a single vendor and sign a $250M contract, you have wasted money by not being more careful about how that capital is allocated. $100M is _a lot_ of capital, and I think it’s easy to lose sight of how much stuff you can do with that much money when applied to industries that don’t pay tech salaries for speculative growth. As examples: how many pounds of food could you grow for 100M? How many doctors could we train for 100M?

I think the thesis is thought provoking. Not sure yet if it’s worth anything, but it also doesn’t preclude businesses from having massive cashflow.

peterlk··on Tailscale has raised $160M
Yes; you will burn through all the capital you raise in ~18 months. It is _extremely_ difficult to efficiently allocate large raises (100M+) in 18 months. In fact, I’m developing a pet thesis that no single human or business can efficiently allocate more than $100M. This would imply that any time a single raise is more than 100M, the investors always would have had a better return by splitting it into chunks of 100M or less. It’s not a _good_ thesis yet, just one I’m performing thought experiments with
peterlk··on The lost boys: how a generation of young men fell behind women on pay
I have no kids, but perhaps positive role models can be found in more specific categories like music. For example, I think Jacob Collier sets a great example. And I think my parents had similar concerns. I was raised on gangster rap and Eminem, and my parents were very concerned about that. But overall, I think I turned out alright. My feeling is that it’s much more important to have role models closer to home. The light that Elon Musk and Andrew Tate are cast in can be greatly influenced by the people around your kids if not directly by parents
peterlk··on The Anthropic Economic Index
I disagree. I think Anthropic, like the other big players, is trying to get some of that government money. Releasing policy-adjacent papers seems like a way to alert government officials that Anthropic ought to be in the room when the money starts changing hands.
peterlk··on Coffee drinking timing and mortality in US adults
I think it’s worth accompanying this study with the Simpson’s Paradox [0]. I don’t want to dismiss the conclusions of the paper, but temper expectations for individuals considering lifestyle changes.

peterlk··on How Japanese black companies oppress workers (2014)
Totally unrelated… I’m really excited to see VR46 as a username, especially since the championship was today
peterlk··on Heart-Rate Recovery After Exercise as a Predictor of Mortality
This seems intuitively true to me. The more I run, the quicker my heart rare matches whatever I’m doing. Resting - low heart rate; running - high heart rate.

If you watch elite runners, they can go from 2+ hours of sprinting (elite marathon pace) to giving an interview in 30 seconds

peterlk··on Scientists successfully breed corals to improve their heat tolerance
I went to Thailand shortly after the covid lockdowns ended, and the corals were all coming back. I talked to a boat captain about it and his comment was: “yeah, there were no tourists to abuse them”.

I can’t help but wonder what effect tourism (and lockdowns) has had on corals. For example, It is common among scuba divers to only use mineral sunscreens because standard off-the-shelf sunscreen floats on the top of the water and blocks UV from the corals

peterlk··on The reason why music is getting worse
A recent technique that I’ve been using is to listen to Spotify radio of my own music. Nobody listens to my music, so I end up finding other music that no one listens to - it’s refreshing. I’m sure you can find a friend who has a garage band or who is a bedroom producer.

The thing is, you have to be willing to listen to music you don’t like. This is a fundamental part of digging and any workflow will expose you to music that sucks

peterlk··on The semantic web is now widely adopted
The article addresses this point with the following:

> It would of course be possible to sic Chatty-Jeeps on the raw markup and have it extract all of this stuff automatically. But there are some good reasons why not. > > The first is that large language models (LLMs) routinely get stuff wrong. If you want bots to get it right, provide the metadata to ensure that they do. > > The second is that requiring an LLM to read the web is throughly disproportionate and exclusionary. Everyone parsing the web would need to be paying for pricy GPU time to parse out the meaning of the web. It would feel bizarre if "technological progress" meant that fat GPUs were required for computers to read web pages.

peterlk··on GitHub was down
Based on what I've read in the past, I believe the secret is simplicity. Simplicity scales
peterlk··on GitHub was down
Can't wait for the writeup! So many services down at once... Something very interesting must have happened
peterlk··on The failed migration of academic Twitter
The largest issue with the fediverse is that so few people seem to understand what it actually is. Even this paper talks about Bluesky, Mastodon, and Threads as if they’re mutually independent. They kind of are, but that misses the point of what the fediverse is meant to be.

I am part of a public mastodon server and the academic migration was like watching people discover what it was like to “surf the web” again. This paper generally rings true to my experience. In my view, this particular failure of fediverse adoption was because there was a large group of people who were using immature technology for the wrong reasons, and the friction of their incorrect mental models outlasted their righteous indignation about Twitter/X.

If you haven’t taken a gander through the fediverse yet, give it a try. It’s beautiful and weird the way the internet was in the days of geocities. But it can take some digging - my best results have been in finding people who are running custom, non-mastodon servers.

peterlk··on Medieval Bologna was full of tall towers
When we stayed in Bologna for a month, we were told that it was used defensively. You can see a very long ways from the top of the central tower (I think it’s closed at the moment). It would have been nearly impossible for an army to approach Bologna without several days for Bologna to prepare
peterlk··on US Justice Department to seek breakup of Live Nation-Ticketmaster
Note that this follows on the heels of the recent (near?) death of California Senate Bill 829 [0] - which is taking aim at the vertical integration of live performance by Live Nation. If you’re in CA, call your representatives!

With this in mind, to continue your rant…

The anticompetitive behavior of Live Nation is toxic to the music and performing arts industries. It’s the Walmart effect, except consumers end up paying way more because exclusivity contracts prevent competition. Artists sign exclusivity contracts with Live Nation, and onlt play Live Nation Venues. Venues purchased by live nation outbid independent venues until those venues sign exclusivity agreements with Live Nation or die, and then Live Nation pushes up the price.

peterlk··on Americans' new TV habit: Subscribe, watch, cancel, repeat
The mismanagement at Dish and DirecTV is staggering. The pendulum has now swung so far in the fragmentation direction that there is real value in bundling disparate content in a restricted fashion, and charging people for it - like cable/satellite bundles. Except now, the business models available are much more diverse because the telemetry of streaming is so much better. Where did the masters of media bundling go?

As a consumer, I really dislike that the media industry has made it my problem to figure out who owns the rights to something. Just take my money and let me see the content. Having to google “<movie> streaming” to see a list of options in different streaming providers who have varying levels of service at different tiers of their paid subscriptions is inane.

Whoever figures out the bundling problem will own a lot of eyeballs, and probably be able to monetize on ads too.

peterlk··on Everything we can't describe in music
The quoted section of the article is pretty out of touch with modern music. Many (most?) genres of EDM place the importance of timbre and texture above harmony and melody
