Having to rely on "some guy hacking some stuff together", in 2025 to avoid accidentally violating visa or tax or some other bureaucratic minutia when there's many governmental bodies/organizations that should have be doing that work since before the Internet even existed seems just totally fine to you? How is this not a free app from some department of the UN? Probably more complicated than "because free apps don't make money", but that is something that late stage capitalism abhors.

I'm not trying to tear down this guy's work, it's a great bit of writing, both English and code, and I'm okay with that pricing model.

What happens when he gets something wrong, simply gets tired of it, or retires, or there's a bus incident?

With options, the market has nearly always priced in the obvious risk. But not the non-obvious risk. Burry is not just saying, “I think these companies are overvalued.” Rather, he’s saying, “I think the bubble is about ready to pop.” While many people see the bubble, Burry is making a bet on the timing of the pop.

You might be interested in reading about the minimum description length (MDL) principle [1]. Despite all the dissenters to your argument, what your positing is quite similar to MDL. It's how you can fairly compare models (I did some research in this area for LLMs during my PhD).

Simply put, to compare models, you describe both the model and training data using a code (usual reported as number of bits). The trained model that represents the data within the fewest number of bits is the more powerful model.

This paper [2] from ICML 2021 shows a practical approach for attempting to estimate MDL for NLP models applied to text datasets.

In the long term, I think civilizations grow along the lines of natural selection. They are neither optimal nor pessimal, but are likely to display a high degree of fitness. Environmental shocks in the short term will challenge fitness. Competition among civilizations also challenges fitness.

Why indeed was Europe technologically advanced? Why were the Americas not so much? Resources are one factor, which is why obtaining resources from other lands is valuable. But the main impetus for advancement surely isn't based on one's "skill in advancing". Most people could be trained to fix cars, if desired. Also, Rome fell, but people now live where Rome was with far greater technology. I posit that, if the indigenous peoples of the Americas were given the desire to advance to the level of Europeans, the resources to do so, and time, similar advancement would arise.

Cooling is conspicuously absent other than a brief mention in the conclusion. As if it has been redacted, because it’s such an obvious and hard problem in space. Which leads me to believe they’ve made progress and aren’t sharing that for competitive reasons. There’s an extremely strong incentive for SpaceX to put GPU on board their birds for local SDR processing power, for applications like SIGINT, high channel counts, etc, and the cooling is literally the only impediment.

In fact everything in this paper is already solved by SpaceX except GPU cooling.

What I once said to a less experienced developer in a code review is:

> Don't write stupid slow code

The context was that they wrote a double-lookup in a dictionary, and I was encouraging them to get into the habit of only doing a single lookup.

Naively, one could argue that I was proposing a premature optimization; but the point was that we should develop habits where we choose the more efficient route when it adds no cost to our workflow and keeps code just as readable.

Intervening as if there were a recession inminent when it is not also has harms (the exact same as the harms when recession interventions are maintained too long or employed too intensely, in terms of inflation, etc.), so I wouldn't agree that your central bank is bad if you happened to have guessed right once, but only if you have a demonstrably accurate objective method.

All depends on what you're doing. When I worked in computational linguistics of languages that don't use ASCII (or European "accented" characters), I was very concerned with the display of non-ASCII Unicode scripts: Arabic, Devanagari, Thaana, Tamil, Chinese, even at one point Cambodian (which was extremely hard to render, even in XeLaTeX--it's improved since then). But at the moment, accented European characters are all I need.

More like $20.

In America, all of that other than the paint is available at the dollar tree. You're looking at ~$7 to fix the hole (spackle, mesh tape, trowel, sandpaper, paintbrush) and $12 to buy a pint can of matched paint, as long as the hole is smaller than your fist.

Larger you would need to add in a $20 patch panel of sheetrock, a razor knife or other sheetrock saw (could probably use the bread knife in a pinch) and a hammer and nails, so closer to $50 all in.

This is a crazy notion. If I have to like everybody to work with them, we can't have a civilization because I don't like most people.

I like some people. Everybody else I work with if they're willing to work with me. Saying that we all have to agree with each other is basically giving up on the political project entirely, and going back to strongman rulers who organize by demanding conformity. Very relevant in these times.

> we should make it as feasible as possible for as many people as possible to never have to do this.

No, we should make it impossible to avoid so people can't sneak into adulthood without being properly socialized.

And you can pretty much choose how long you want your day to be (within limits). The ISS has a sunrise every 90 minutes. A ~45 minute night is obviously much easier to bridge with batteries than the ~12 hours of night in the surface. And if you spend a bunch more fuel on getting into a better orbit you even get perpetual sunlight, again more than doubling your energy output (and thermal challenges)

I have my doubts that it's worth it with current or near future launch costs. But at least it's more realistic than putting solar arrays in orbit and beaming the power down

> What's wrong with you?

I hold little respect for people who skip voting and then complain about the result of the voting.

When I was a kid, Florida was a swing state, and Georgia was a red stronghold.

No. But I wish we had Australia's mandatory voting.

> Whatever thinking fundamentally is, it also has an equivalence as a mathematical transformation of data.

Do not confuse the mathematical description of physical processes as the world being made of math.

> You're assuming the conclusion by saying that the two mathematical transformations of data are not isomorphic.

Correct. They're not isomorphic. One is simple math that runs on electrified sand, and one is an unknown process that developed independently across a billion years. Nothing we're doing with AI today is even close to real thought. There are a billion trivial proofs that make the rounds as memes, like one R in strawberry, or being unable to count, etc.

I use Purelymail, they're a tiny operation, but I've never had a single mail delivery issue. They're also by far the cheapest for most personal usecases. Their pricing is kind of "honor" based, you get simple pricing at 10 dollars a year without limits, unlimited users, domains, storage etc., but if you go overboard with it they'll ask you to use advanced pricing, which honestly is even cheaper, at least for my personal mail that I use like a normal person (a few incoming mails a day, one or two outgoing mails per week), advanced would be at.. 3 dollars a year or something.

My second option would be Migadu, though I've not tried them myself yet (I have zero complaints with Purelymail and will use them for as long as they exist).

Another thing I kind of wanted to try is to run a basic mail server on my own hosts, and send the mail through a provider like Purelymail or something, for full control over storage and backups, has anyone here tried that?

> My stance is it's (obviously and only a fool would think otherwise) never going to be conscious because consciousness is a physical process based on particular material interactions, like everything else we've ever encountered.

Seems like you have that backwards. If consciousness is from a nonphysical process, like a soul that's only given to humans, then it follows that you can't build consciousness with physical machines. If it's purely physical, it could be built.

Yea, this seems to be sort of analogous to companies who check whether you have a rooted device in order to take some kind of action (usually preventing the software from running). If that's a shitty thing to do, then this is, too.

Software should not be in the business of trying to (badly) guess whether the user is the right sort of user, based on inexact signals from the operating system. As others pointed out, the false positives will be annoyed, and the true positives will sidestep your efforts.

My neighbor just did the exact same thing. The way FAT filesystems work is they change the first byte of the filename to an invalid character to make them a tombstone.

Since he hadn't used the SD card yet, we were able to restore the files with "TestDisk", a companion tool that ships with PhotoRec. Under "Advanced" there is an "Undelete" tool. This will let you browse the filesystem, find your missing files, and copy them to another drive.

For those old enough to remember, MSDOS came with undelete.exe which worked the same way.

Assuming you meant how so. I can comment to that.

Stuff like you have to pay as an attendee for things that used to be free, like to see who's attending, it costs a lot to run a group now (something like $200 per year?), and they pop up with ads/offers after many kinds of interactions like RSVPing

I don't think you're being confrontational, and I don't think it's a problem either to be honest. My point was more that, try as one might, you can't build the ultimate curated list of non-political follows because somebody will eventually write something that you consider political. It can't be avoided, which I think is what you're saying too.

I personally think that people try too hard to avoid politics and shame those who "make things political" – especially in tech. We live in an inherently political world, and our industry is increasingly political as it's co-opted by political figures and even dictators across the world. Trying to avoid talking about it is like stuffing our fingers in our ears and pretending reality isn't real, imo.

No, but building bridges is a good example - it's also a solved problem. Show civil engineers a river, tell them how much and what type of traffic needs to allow it, and they'll tell you it obviously can be done, they'll even tell you what structural elements will be needed and roughly how expensive they are. The problem to solve here isn't whether this can be done, but which off-the-shelf parts to use to make a design that you can afford.

We're past the point of every satellite being a custom R&D job resulting in an entirely bespoke design. We're even moving past the point where you need to haggle about every gram; launch costs have dropped a lot, giving more options to trade mass against other parameters, like more effective heat rejection :).

But I think the first and most important point for this entire discussion thread is: there is a paper - an actual PDF - linked in the article, in a sidebar to the right, which seemingly nobody read. It would be useful to do that.

This part I don't grasp:

> this global coordinate system isn't a continuous mapping (see the discontinuity of both angular coordinates between 2*pi and 0).

I'm guessing that the issue is that I don't know your definition of 'continuous'.

I believe every point on the planet (sphere, for simplification) has unique corresponding coordinates on the map projection (chart). The only exceptions I can see are, A) surfaces perpendicular to the aspect (perspective) of the projection, which is usually straight down and causes points on exactly vertical surfaces to share coordinates; B) if somehow coordinates are limited in precision or to rational numbers; C) some unusual projection that does it.

> A sphere requires at least two charts for an admissible atlas (say two hemispheres overlapping slightly at the equator, or six hemispheres with no overlaps), otherwise you get discontinuities.

There are cartographic projections that use two charts. Regarding those with one, where is the discontinuity in a Mercator projection? I think when I understand your meaning, it will be clear ...

Normal Erlang code has a fixed number of reductions (function calls) before it must yield to a scheduler. Processes also have their own stacks and heaps and run garbage collection independently. The result is that no single process can stop the whole system by monopolizing CPU or managing shared memory.

The Erlang runtime can start a scheduler for every core on a machine and, since processes are independent, concurrency can be achieved by spawning additional processes. Processes communicate by passing messages which are copied from the sender into the mailbox of the receiver.

As an application programmer all of your code will run within a process and passively benefit from these properties. The tradeoff is that concurrency is on by default and single threaded performance can suffer. There are escape hatches to run native code, but it is more painful than writing concurrent code in a single-threaded by default language. The fundamental assumption of Erlang is that it is much more likely that you will need concurrency and fault tolerance than maximum single thread performance.

I don't think that's proven out, like, at all; measure it against the returns on hardening mainstream platforms. The "monoculture" security thing has always been overblown, not least because you're never going to get an ecology where you have enough diversity to matter. Having 3 mainstream desktop or phone options is only marginally better than having just 1, and you're never going to have 20.

Great question, and yes, it's quite different: Plexe generates code for a pipeline that processes your dataset (analysis, feature engineering, etc) and trains a custom ML model for your use case. When you call `.predict()`, it is that trained custom model that provides the response, not an LLM. The model is also hosted for you, and Plexe takes care of MLOps things like letting you retrain the model on new data, evaluating the model performance for you, etc. Using custom specialised models is generally more effective, faster and cheaper compared to running your predictions through an LLM when you have a lot of data specific to your business.

> Teams need notebooks that are reactive, collaborative, and AI‑ready

reactive: this matters, but all the alternatives have it

collaborative: this matters very little in the Figma / Google Docs sense of collaborative in practice. It's very rare you want two people working on the same notebook at the same time. What you really want is git style version control.

AI‑ready: you want something as close to plain python (which is already as AI-ready as it gets) as possible.

if you're measuring across these dimensions, I'd go with marimo.

marimo is saved as plain .py files, easy to version control and has a reactive model.

My two cents... He might think the bubble is about to burst; he might be hedging his downside risk after a serious rise in his overall portfolio, picking the two stocks he thinks are the most out of whack valuation-wise to execute that hedge (the premium for the puts would likely be a fraction of the paper gain he's sitting on so not the end of the world if they expire worthless); he might be hedging significant material gains in these exact two stocks; he might be doing it for some only-billionaires-get-it reason. I guess I'm just saying that the reason could be pretty detached from "I think the bubble is about to burst!"

> Are you really going to hire that developer because you need extra manpower to stand up test coverage? No, so as far as that developer is concerned, AGI has arrived for that part of their professional career.

That is exactly what you need in order to make AI useful. Even a baby needs to cry to signal its needs to parents, which are like ASI to it. AI working on a task lacks in 3 domains: start, middle and finish.

AI cannot create its own needs, they belong to the context where it is used. After we set AI to work, it cannot predict the outcomes of its actions unless they pass through your context and return as feedback. In the end, all benefits accumulate in the same context. Not to mention costs and risks - they belong to the context.

The AI is a generalist, context is exactly what it lacks. And context is distributed across people, teams, companies. Context is non-fungible. You can't eat so I get satiated. Context is what drives AI. And testing is the core contextual activity when using AI.

That would be incredible! Personally I only buy the stuff I can find inside the country, inside the country. But then some stuff I have to order from Germany/France/Italy when it's only available outside our borders.

He's been bearish for the last n years. His Twitter handle is Cassandra because he tries to warn people about impending doom, but nobody listens. He gave up at one point because he tweeted SELL and then everything was fine.

tl;dr he's a perma bear.

I actually don't think he's wrong, but one thing I've learned is that it's not enough to recognize a bubble. Almost everyone sees the markets are, as they say, frothy. But you need to see if there's a needle nearby. Without that you're just trying to get lucky.

Puts especially are really hard because they expire. They limit your loss compared to shorts, but you need to time it perfectly.

With wind? Sure. With solar PV? Only recently. You're still going to need a watermaker to make fresh water, and consumables for it, along with food, but with enough solar, it is very compelling when you might have challenges sourcing diesel (whether financially or logistically). Scratches the self sufficiency itch to an extent, sailing solarpunk style.

When my friends and I were undergrads (3rd year, I believe), we had an absolute blast exploring this exact topic - the intersection of Bloom Filters and client side searching. So much so that it became part of our undergrad thesis.

It all started when Stavros's blog was circulated on Hacker News! The way we approached the search part was by using "Spectral Bloom Filters" - https://theory.stanford.edu/~matias/papers/sbf-sigmod-03.pdf - which is based on a paper by Saar Cohen and Yossi Matias from the early 2000s - its basically an iteration on the counting bloom filters. We used the minimal selection and minimal increase algorithm from the paper for insertion and ranking of results.

I wrote a blog on it too - https://pncnmnp.github.io/blogs/spectral-bloom-filters.html

Some slides - https://pncnmnp.github.io/blogs/sthir-talk-2020.pdf
