> My pet hypothesis for years is that this must be the result of an evolutionary arms race within the species.

Frans de Waal studied primates and defended just this hypothesis. He wrote a bunch of books, so you may be interested in reading at least some of them.

BTW, my pet hypothesis is the social roots of our intelligence is the reason why people mostly hopelessly dumb. They kinda go on intuition and it works in normal social situations, but when it comes to politics or science the intuition fails them. One needs to train their mind to stick to logic and rationality, without taking sides which seem the most beneficial for them. But training is hard and training can easily be overcome by the intuition, which is the natural way for brain to work. You need to keep your brain working against its nature to not lose your intelligence in situations which are not hierarchy games.

>A lot of context I get from just reading results from a traditional search engine is lost when I get an answer from a LLM. I find it somewhat uncomfortable to just accept the answer, and if I have to double check it anyways, the LLM's answer is kind of meaningless and I might as well use a traditional search engine.

And this is how LLMs perform when LLM-rot hasn't even become widely pervasive yet. As time goes on and LLMs regurgitate into themselves, they will become even less trustworthy. I really can't trust what an LLM says, especially when it matters, and the more it lies, the more I can't trust them.

> But you remove all healthcare and social support for trans people

What does that even mean? Healthcare is a mess for everyone already. Social support? What does “social support” in the context of trans people actually entail? Spending enough time and resources to normalize the concept? Support what? How?

If you think somehow bigots will eventually change their tune, I have a bridge to sell you.

> Mistake #1: Calculating tsvector On-the-Fly (Major issue)

I'm shocked that the original post being referred to made this mistake. I recently implemented Postgres FTS in a personal project, and did so by just reading the Postgres documentation on FTS following the instructions. The docs lead you through the process of creating the base unoptimized case, and then optimising it, explaining the purpose of each step and why it's faster. It's really clear that is what it's doing, and I could only assume that someone making this mistake is either doing so to intentionally misrepresent Postgres FTS, or because they haven't read the basic documentation.

I don't think there's anything wrong with exploring a field for decades. There are many scientists who have a mix of successes and failures. But this guy spend his whole life and many years of other people's lives trying one single thing that never really worked. You could call that being a single-minded visionary, but I don't think it's unreasonable for others to think it either kooky or a giant waste.

A useful comparison to me here is all the alchemical efforts to turn lead into gold. Can modern physicists do that? Not economically, but sure. [1] If alchemists had just persisted, would they have gotten there too? No, it was a giant waste, and pretty loony to a modern eye. And I'd say both alchemists and a number of AI proponents both are so wrapped up in pursuing specific outcomes (gold, AGI) that they indulge in a lot of magical thinking.

It depends. Sometimes webpages are useful, but at the same time navigating the amount of fluff on webpages nowadays takes longer than asking a LLM.

I asked Claude to give me a recipe that uses mushrooms and freezes well and it give me a decent looking soup recipe. It might not be the best soup ever, but it's soup, kinda hard to mess up. The alternative would be to get a recipe from the web with a couple dozen paragraphs about how this is the bestest soup ever and it comes from their grandma and reminds them of summer and whatnot.

I find introspecting about how I formulate the question and what works better or worse for me personally fascinating.

I am content to use the AI to perform "menial" tasks: I had a textfile in something parsable by field with some minor quirks (like right justified text) and was able to specify the field SEMANTICS in a way that made for a prompt to an ICS file calendar which just imported fine as-is. Getting a years forward planning from a texttual note in some structure into calendar -> import -> from-file was sweet. Do I need to train an AI to use a token/API key to do this directly? No. But thinking about how I say efficiently what fields are, and what the boundaries are, helps me understand my data.

BTW while I have looked at a ICS file and can see it is type:value, I have no idea of the types, or what specific GMT/Z format it wants for date/time, or the distinctions of meaning for confirmed/pending or the like. These are higher level constructs which seem to have made useful distinct behaviours in the calendar and the AI description of what it had done, and what I should expect lined up. I did not e.g. stipulate the mappings from semantic field to ICS type. I did say "this is a calendar date" and it did the rest.

I used AI to write a DJANGO web to do some trivial booking stuff. I did not expect the code to run as-is, but it did. Again, could I live with this product? Yes, but the extensibility worries me. Adding features, I am very conscious one wrong prompt and it can turn this into .. drek. It's fragile.

Very likely the site is well optimized. It's optimized for search engines, which is why we found the site in the first place, which is in turn the reason I said "very likely" in the first sentence: we come upon web sites not truly randomly but because someone optimized them for search ranking. It also appears from your "without an ad blocker" that the site may be optimized for ad revenue, monetizing our visit as much as possible. There's probably optimization of tracking you in order to support those ads, too.

What you're complaining about is that the site is not optimized for your reading enjoyment. The site is probably quite well optimized, but your reading enjoyment was not one of the optimizer's priorities. I think we agree about how annoying that is and how prevalent, so the news that new typographical features are coming seems to me like good news for those of us who would appreciate more sites that prioritize us the readers over other possible optimization strategies.

google and bing are much worse now. I cant find anything. I cant remember the last time a discussion [platform] made it into the results. Kinda comical how even the ads are terrible. I think they discover it is better for me to keep searching rather than buy anything?

Twitter and reddit are garbage.

I sometimes use youtube search then fast forward with the subs on and the sound off.

The internet has ended. It's been a fun ride, thanks everyone.

“Withheld” has a specific meaning in this context. As explained in the subsequent order (appendix page 11a of the material I linked above: “Withholding of removal, in contrast to asylum, confers only the right not to be deported to a particular country rather than the right to remain in the U.S.”

Garcia was deportable. He was only not deportable to El Salvador.

> capitalism is that it isn't a thing at all. It's the absence of a thing. It's a positive freedom.

This is very wrong. Capitalism fundamentally requires abstract property rights (i.e. someone can own a thing they have never even held or seen, much less used), and it requires a state to provide very strong protections for those abstract rights.

In the absence of the state imposing such a property right regimen, you wouldn't have capitalism, since it'd be impossible to accumulate capital if the only way to own property is to physically use and/or occupy it.

Importantly, capitalism is not the same as free markets! Humanity has had free markets in one form or another for most of its history, but capitalism is very recent historically speaking.

The notion that socialism is always anti-individualistic is also wrong. Left-wing libertarianism is a thing, and goes back to the earliest anarchist writers (who literally invented the term "libertarian" as a political label - and they didn't have the likes of Ayn Rand in mind when they did that). There's even free-market left-wing anarchism.

One of the "big things" people would joke about alongside solving world hunger was world clothelessness. People don't seem to realize that in our global economic state (at least a week ago) we solved that problem so hard that there's a pile of clothes in the atacama desert¹ (not to say it's without its consequences). Plastic microfibers are a problem I admit, but I would happily eat my weekly credit card(/s) knowing that far fewer people have to go naked. I for one hope that thrifting can fill the gaps, it may take a while to replace the 8000+ laborers that take part in making your white t-shirt² and maybe more.

It's definitely not straightforward, there was no 8k originally AFAIK, that came through a firmware update and as far as I know is a totally different format that makes use of ticoRAW as a base (https://www.dpreview.com/news/9624409613/nikon-is-licensing-...), so RAW video isn't recorded in the same format as RAW photos (N-RAW vs NEF).

It can only do 8k60 though, not 8k120, so obviously the video pipeline and the C120 pipeline aren't identical.

When you say it doesn't go into DX mode for 11MP, you're correct for C120, but for C60 it /does/ go into DX mode (which captures a 19MP image). How this differs between C60 and C120, I'm not entirely sure in the camera internals. I had thought the resolution reduction is from cropping, but confirmed in the manual that when you enable C120, it's an 11MP photo but is full frame (no cropping).

Obviously this stuff is complex (maybe overly complex) and I haven't delved into it super deeply since I don't need it for my type of photography (and I never do video).

I hate woodpeckers. We had a solid year or two where there was one putting holes in our house and it just would not leave us alone. Eventually we were able to figure out a way to prevent it from perching, but until then I was on the verge of wanting to sell the house just to get away from the thing. I used to joke that the people who made the migratory birds treaty which protects woodpeckers only did so because they never had to deal with one before.

Using search engines are still _significantly_ faster for me for the vast majority of the queries I want answers for.

The results from LLMs are still too slow, vary too much in quality and still frequently hallucinate.

My typical use-case is that when I'm looking for an answer I make a search query, sometimes a few. Then scan through the list of results and open tabs for the most promising of them - often recognising trusted, or at least familiar, sites. I then scan through those tabs for the best results. It turns out I can scan rapidly - that whole process only takes a few seconds, maybe a minute for the more complex queries.

I've found LLMs are good when you have open-ended questions, when you're not really sure what you're looking for. They can help narrow the search space.

Calling CECOT a prison does a lot of heavy lifting. People are kept 20+ to a cell, without even basic amenities like running water or mattresses. The salvadoran government openly states that nobody will ever be released from the 'prison' [1]. These conditions are harsher than even the conditions nazis kept victims of the holocaust in. It is overtly a death camp, which the salvadoran government built as a backward way of getting rid of poor people by exterminating them rather than meaningful policy to improve the lives of it's citizens.

You could broaden beyond the rust belt: America is a rich country that manufactures fancy things. A smart trade policy would focus on these things; it would not make policies to be competitive with poor nations. We tariffed places that export commodities or low-value-add products, places that we import ingredients from to make the fancy things.

Taiwan and China are related specifically on semiconductor trade; its the hottest point in our "battle" w/ China. TSMC is really the only company in the world that can make the best chips. Losing their trust is itself a security risk.

On the last point, I agree it would increase labor competitiveness, but I don't think its smart to compete with the whole world. If we wanted to do this, we should set policies to make skilled Americans competitive in the manufacturing industries that already exist here.

The most powerful 360/91 was roughly equivalent to a 20MHz 486 from the early 90s.

Mainframes had much more powerful distributed IO for multiple hard drives, tape systems and such.

But the CPUs were really not all that powerful at all.

Many people wildly underestimate just how insanely fast and power-efficient today's commodity computing is compared to high-end supercomputing from earlier decades.

A Raspberry Pi destroys any supercomputer earlier than around 1990, and gives some later models a run for their money.

An Apple S7 watch processor is maybe 25X faster than a Pi 5.

And so on.

The judges didn’t rule otherwise. They had no reason to do so, because Garcia’s filing in the district court conceded he was deportable. “The government could have chosen to remove Mr. Abrego Garcia to any other country on earth.”

Note: it looks like you’re quoting from news articles describing the judicial decisions, instead of reading the decisions themselves. That’s like quoting from news articles about software code. They’re not reliable sources.

Yes? I don't hate LLMs and I don't think I ever have. They are super useful and neat, I use them all the time from smolguys on my computer to Claude in the cloud. It's like saying "I hate forks" or something, like why do you hate a generic tool that has many applications? I love that I have these things for free at home forever, my personal wiki and time tracker have both gotten way more useful ever since I baked an LLM in.

But I appreciate and read the Google Gemini AI generated response at the top of the page.

Also, I'm an iPhone user. But I have a Google Pixel phone for deve work.

I find myself now using 'Hey Google' a lot more because of the Gemini responses.

The article is correct. T(z) (in the warmup problem) is the generating function that counts the number of rooted ordered ternary trees, i.e. if we write T(z) = t_0 + t_1z + t_2z^2 + …, then t_n is the number of such trees with n nodes.

Yes there is no "simple" generating function, i.e. there's no simple expression for T(z). Nevertheless, T(z) (as further explained in another comment here in this thread) satisfies the equation T(z) = z + T(z) + zT(z)^2 + zT(z)^3, and this fact can be used to find the coefficients of T (i.e. the numbers t_n) via Lagrange inversion, and the code in the post does so and gets the same numbers as https://oeis.org/A036765.

(You use the term "characteristic equation", but that is a term only used in the context of linear recurrence relations AFAIK, and not applicable here.)

(Also IMO the post does not overcomplicate anything; what it presents is in fact the easiest way of solving the problem — that of finding the asymptotics of the number of unordered rooted ternary trees, up to isomorphism. If you think you have a simpler method even for counting small cases, feel free to post an answer at https://math.stackexchange.com/questions/5050941/counting-tr....)

Every time I scroll through r/wallstreetbets or r/cryptocurrency I realize that I understand something about risk and patience that many young people do not. I am not disrespecting individual investors and I don't hate btc (tbh I don't invest in it either).

It's obvious that a lot of people feel like they have to find a way to get rich in the next three years or they will be poor forever. I am sure my generation was often the same. But people who have been through good times and bad times understand risk and patience.

The blog post mentioned that "The eBPF flow logs provide a comprehensive view of service topology and network health across Netflix’s extensive microservices fleet, regardless of the programming language, RPC mechanism, or application-layer protocol used by individual workloads."

Service mesh may have restrictions on the network protocols and may not cover all network traffic (like connections to Kafka and databases).

Intelligence can be pretty well defined as something like: the ability of an organism to make an internal model of the outside world, and use that model to predict the world and plan its actions.

There is of course a lot of variation in which things the model emphasizes and how much simulation is done, but that's the gist of it, and there are lots of ways to measure it in animals.

This is an incorrect response.

Firstly, "Evolutionary Arms Race" is not tautological, it is a specific term of art in evolutionary biology.

Secondly, "evolutionary arms race" is a correct answer, it is the general case of which the Red Queen hypothesis is a special case. I do agree with you that OP described a Red Queen case, though I would hesitate to say it was because of "equilibrium"; many species in Red Queen situations have in fact gone extinct.

Synthesizing what would be multiple searches into one prompt is where they can be really useful.

For example: Take the ingredient list of a cosmetic or other product that could be 30-40 different molecules and ask ChatGPT to list out what each of them is and if any have potential issues.

You can then verify what it returns via search.

Most of the VPS providers have been implementing variations of this for a few years now. Most of them will not block ports on accounts created before a certain date and will open the ports for people that open a ticket and state they will not be sending UCE and are responsible postmasters that will secure their mail servers inbound traffic and accepting an agreement that if they abuse it or let someone else abuse it their account is gone. Seems more than fair to me. It's a nice alternative to having to say, "and this is why we can't have nice things." We can have nice things.

That's something different than specialization.

Suppose you have enough mining production to meet half of domestic demand. Then you still have mining production, and know how to do it, and if it was necessary you could scale it up or reduce domestic consumption somewhat from the uses that aren't as important. Whereas if you outsource all of it or nearly so, i.e. actual specialization, it's a vulnerability whether to enemy action or just a single point of failure that subjects the whole world to unexpected localized turmoil in the only place that makes that.

I was among the first to champion AI search, even before Perplexity rose to fame. You.com was the first AI search to quote sources well, and I used it extensively.

But now, the veracity of most LLMs' responses is terrible. They often include “sources” unrelated to what they say and make up hallucinations when I search for what I'm an expert in. Even Gemini in Google Search told me yesterday that Ada Lovelace invented the first programming language in the 18th century. The trust is completely gone.

So, I'm back to the plain old search. At least it doesn't obscure its sources, and I can get a sense of the veracity of what I find.

I'm going to just toss the entirety of your comment out to focus on the last line. Yes I can. We all lived through the same 4 years, saw and felt the disaster the first time, and now we're fucking doing it again. If your only policy issue is that you don't think women & gay people deserve rights & you want to be able to use slurs with impunity, you don't have policy positions.

Nobody should be falling into the trap of trying to approach these people as rational actors with a coherent idea of what they want or how the country should be run. They've proven to us, twice in the last decade, that they don't have anything resembling a serious idea.

I'm sure this comment will get flagged & I'll probably get a note about remaining civil, but fuck this whole comment. You may feel fine hand waving, equivocating, & telling yourself this is "business as usual." Sit this one out. Your head isn't in the game and the stakes are different this time.

> with grep

Maybe for an extremely limited number of people. For the rest of the world, it meant searching the web, books, or scholarly publications, reading a ton, taking notes, and then possibly creating a report. Which is pretty much exactly what these AI agents are claimed to to, so deep research is the perfect name for it. Whether or not they are good at it compared to humans is a question that hasn't been answered to my satisfaction yet, but the name I'm fine with.
