If I'm not mistaken, the US has one of the, if not the, highest per capita spend per student in the world...but most of it goes into administrative costs and students never see it. It's a big problem. It's unfortunate that many of the people saying this also have questionable politics on other serious topics that drown this point out. Democrats are beholden to the unions in education, so they won't bring it up.
Think of everything in the world as objects with springiness , nothing is "absolutely rigid" , rigid objects in Newtonian mechanics are really really tight springs that deform very little to push back with a huge force.
So a "rigid" block on a "rigid" table is really two springy objects that deform to equilibrium i.e when the normal force exactly equals the weight of the block
It's fairly easily explained by just thinking of the surface as being covered in tiny springs, or trampolines maybe. Just these are tiny springs made of electromagnetic forces.

Anything sitting still on the surface is compressing the springs exactly enough until they push back enough to resist further compression, and not enough that they push more. This is a stable equilibrium.

The normal force from a surface can exceed the force needed to just push back against the weight of an object, if you can compress the springs enough. That's why things can bounce.
So then they'd have formed on earth - no panspermia required?
I am absolutely sure that if Chatgpt created a google like interface on a domain like askme.com. without a required login, it would become immensely popular. Possibly eating away a lot from traditional search engines.
Google search is becoming the new Yahoo. Its becoming bloated if not already. And its just time for a new era in which a chatgpt like product perfectly fits.

Maybe because a Roomba weighs ~9 lbs but a sofa or table weighs 2x to 10x more.

I can answer your actual question by pointing out robot vacuums lack arms or any feature capable of lifting anything. That’s “why” they don’t lift things.
The hashtag index is not going to be any bigger than the tweets storage though, and may be significantly smaller, so this part is not if by an order of magnitude (even a binary one). Assuming something like a common SQL database is used for storage there would be a tags table (one row per unique tag, tag string plus a numeric identifier, indexed by both which bloats the size a bit but it'll still be small) and a link table (one row per tag in a message, containing the tag and message ids). Even if using 64-bit IDs because you don't want to fall over at 2 thousand million messages (or 4, if your DB supports unsigned types or you start at MININT instead of zero or one) then that structure is going to consume about 32 bytes per tag per message (plus some static overheads and a little more for non-leaf index pages of course). In theory this could be the same size as the messages table or even larger (if most messages contain many small tags), but in practise it is going to be significantly smaller.

Yes, this would be big enough to need specifically factoring into a real implementation design. But it would not be big enough to invalidate the proposed idea so I understand leaving it off, at least initially, to simplify the thought experiment.

Similarly to support a message responding to, or quoting, a single other you only need one or two NULLable ID references, 16 bytes per message, which will likely be dwarfed by the message text in the average case. Given it likely makes sense to use something like SQL Server's compression options for data like this the average load imposed will be much smaller than 16 bytes/message.

We are fiddling, fairly insignificantly, measurable but to massively, with constants a & b in O(a+bN) here, so the storage problem is still essentially of order O(N) [where N is total length of the stored messages].
Can you use ChatGPT without a phone number yet? I thought about signing up a while ago but don't see a reason they need my phone number. Popular VOIP numbers don't work either.
No tool; mostly a reminder-to-self to keep an eye on comments from those users. Also helps when researching keywords on hn.algolia: For ex, "gpu pcwalton", "trust mjg59", "advice nostrademons" etc

But since people already complain that it does too much post processing, it seems like a dangerous road to try and do even more of it.

As long as you let me turn it off, hey, party on, knock yourself out with postprocessing hackery.

The first part -- the easy part -- is the problem Apple can't seem to manage.
This is the problem with science communication today. We can either be nuanced and the message can be taken whatever way a person wants to hear it, or we can be direct and people accuse you of ignoring nuance.

As a first order approximation, the lakes are drying from diversions. At second order, its diversions, climatic variability, and AGW. In reality: what about the feedback from aquifer depletion, does evapotranspiration from crops offset this from increased rainfall, and to what degree compared to native biota? Natural systems have irreducible complexity that no one wants to hear about.
I'm not sure why this would be in the goals / positives.

> Tools that automatically remove busywork, such as dependency-injection frameworks and auto-mocking frameworks, are not required.

The examples are basically doing manual DI. You don't need more in this small case case, but if you're actually using specific implementations for test, why not help yourself by reducing that busywork?

You can always fall back to manual parameter where needed even if you do use DI, so using one is typically not restricting you in any way.
And because of how it responds to them, people often forget that ChatGPT is just a language model, not an all-knowing AI.
As a side note:

> I did all my calculations for this project using Calca (which is great although buggy, laggy and unmaintained. I might switch to Soulver) and I’ll be including all calculations as snippets from my calculation notebook.

I've always wanted an {open source, stable, unit-aware} version of something like this which could be run locally or in the browser (with persistence on a server). I have yet to find one. This would be a massive help to anyone who does systems design.

It is funny when the dog catches its tail, but having worked for Harvard as an individual contributor for quite some time until recently, I think this is more an artifact of how many things Harvard does rather than some vast bureaucratic inefficiency. It's forestry program, pharmaceutical research, real estate development, giant dining organization, handful of public theaters, 72 (seriously) libraries, most being domain specific, police department that has the third largest jurisdiction in the state (on paper but they really only deal with university stuff,) their hospitals, and the zillions of other things they do can only take so much centralization. It's a bloated bureaucracy, for sure, but it doesn't hold a candle to The Fed, and IBM beats them both by a mile.

Rather a liberating blow; actually, the goals were not achievable with the existing systems.
Bureocracy is easy to create and almost impossible to destroy. I think its one of the main reasons start ups beat out established competitors who on paper can bring much more resources to bear.

I dont think its just in our time either. I'm sure Rome had quite a bureocracy in its day.

Apparently it costs OpenAI a couple cents per prompt. So I assume this is an attempt to limit spam to keep costs down.
I’m a bit surprised that a product manager for a search team would put forward arguments like this. ChatGPT isn’t a search engine, but that doesn’t mean it won’t be a significant part of a search engine product.

Query correction is a common component in search engines. “Did you mean” is everywhere. It is just one component in a search pipeline.

The stupid simple integration I’m sure Google will release is to put ChatGPT on top of the search results rather than the query itself. The question at that point is the economics of it: how much does it cost per query, and how much extra value can Google derive (or avoid lost value i.e. lost customers).

This is an advantage that Google has over upstarts like Kagi and DDG: Google can keep their cost per query much lower since they don’t buy their results from other sources.
Yes good luck trying to order from a vendor catalog using the SAP front end, enter the correct shipping info and get any UI confirmation or cues the order was input correctly and will be sent to you. Maybe our implementation is just broke, but there are so many unintuitive backwards UX patterns I shudder to use it every time.

> Do you claim there is no private discussion among Apple engineers about WebKit bugs that have been put "InRadar"?

Open source bugs will have private/non-public conversations (whether it's in person, or on slack, or on a seperate issue tracker) all the time. That's not abnormal or all that damning.
Your "simple math" is pretending that once a UBI payment is made, its value is just consumed and totally disappears. You are not taking into account the velocity of money, that is how many times a unit of currency mediates trade. A meaningful UBI would be like a stimulus without inflation, since the total money supply need not increase.

I'd also say, unstable part-time gig work that does not allow financial independence also does a pretty good job of disincentivizing work. If you're going to end up poor, why not just be poor without the added hassle of work?

I'm enjoying that interview right now - thanks for sharing!

I also identified with the rest of your post. I've felt regret recently for the career "potential" I lost to the inner struggle, and at around 15 years in, I think I understand these dynamics well on an intellectual level, but emotionally, I feel further than ever from being able to overcome them.
Indeed. If you read between the lines, there are some hints that internal design / engineering issues + supply chain snafus left Apple with a mismatch between their new camera system and the SoC that supports it.

To me, the clearest signal of this is what Halide can and can’t do with the new Pro sensor. In ideal lighting, the Halide-processed 48MP JPEG shots look insanely good, with strand-of-hair-level detail. It’s hard to imagine Apple wouldn’t have wanted to show off the ability for ordinary users to take these shots. But capture speed is several seconds, and if conditions aren’t ideal, even that isn’t enough to get a clean shot.

Like MKBHD said about Google & the Pixel: Apple needs a generation or two for computation to be optimized for the capabilities of their new sensor.
I think one of the big unstated challenges (but implied by the reference to needing a bootloader exploit) is that KTRR/CTRR [1] prevents new executable kernel code from being introduced after the device boots, even if the kernel is fully compromised. This is a hardware feature and is not one that has (publicly) been bypassed in recent memory. In other words, without a bootloader exploit it is not possible to map the macOS kernel on an iOS device

That's super interesting. Someone should start investigating that line to treat autoimmune diseases.
Most things have a golden middle amount, where its great in the right amount but sucks if you have too much or too little. Bureaucracy is no exception. Trying to make a large group of people work towards a common goal effectively is really hard without some management. Too much though is extremely stifling.

This is just as untrue as it was for Covid. Some people are asymptomatic with flu, others mildly ill, others bedridden but for an unpredictable period of time, and others are hospitalised or killed. Without a PCR test it’s just a non-specific viral infection.

Colloquially flu is often reserved for a non-specific viral infection that makes you very unwell, but that could be a “common cold virus”, while somebody with a “cold” might be suffering from influenza!

I’m surprised that this belief still holds despite the wide exposure to higher quality information on this topic during the pandemic.
A Twitter-like service that fits on a single server could probably get by with the reduced revenue that comes with not offering obsessively fine-grained analytics and ad targeting.
I've had some luck teaching middle schoolers Python using the turtle module. (I think we used IDLE.) I think it depends on the child and their interests, ultimately.

If you were able to index the same amount of content you'd have a damn good alternative. And that's the level of this experiment.
MIPS can use either big or little endian modes, though. SGI used MIPS in big endian mode, but some of the stuff out of China using MIPS today is little endian. Some devices include a hardware switch that lets you choose.

ARM also supported both, but you don't really see ARM used in big endian mode today.

This is one that I like a lot. Years ago (1997 timeframe) I had implemented it in a Java compiler, and a few years later in a Java library (https://github.com/oracle/coherence/blob/4e6e343e1ffd9bbfea3...) that would create an exception on the assertion failure and parse its stack trace to find the source code file name, and read it to find the text of the assertion that failed, etc. so it could build the error message ...

In Ecstasy, we built the support directly into the compiler again:

val a = 1;
val b = 2;
assert a == b;

Produces:

IllegalState: a == b, a=1, b=2
IMO I think addictiveness is a matter of dosage. A lot of ADHD people who have these medications can forget to take them, stop taking them for days in a row, don't want to take them because of side effects and stop taking them for years after years of usage or only take them during school & work days, which all doesn't sound like addictive behavior to me. In practice junky addiction comes from junky usage patterns and behaviors.
So just like a typical explanation of things for five year olds?

It’s a time capsule, for sure. For me, the most compelling thing about the book is the strange dichotomy between the sober author dressed in his three-piece white suit on a bus with young hippies and old beatniks in 1964, trying to write it all down for posterity. That’s compelling when you start to look at the entire book from that POV. It couldn’t have been an easy task.
These are not quite "true" monopolies however because the market for laundromats or car washes is still open to entry, i.e. contestable by others. The apparent monopoly is in fact checked by the "virtual" competition that might be expected to appear if it becomes too inefficient. True monopolies are generally a product of real barriers to entry, which are indeed possible on the Internet. Reasonable users will be aware of this though, and prefer more open platforms where even prospective competitors are free to interoperate with the incumbent, and there's no undue lock-in.

The remaining obstacles amount to things like IP regulation, that can prevent entry even by a more open competitor.

I'm starting to think that given enough time and space any context in which self replicating structures can occur will give rise to some form of life (as a statistical inevitability).

(I've probably been reading too much sci-fi.)

Alien life does not need to be restricted to matter as we know it; if space itself can give rise to self replicating structures, then it too could be alive.

Beyond that, life could occur in any medium and at any scale (in either space or time).

Even regarding terrestrial life, how long did it take for us to notice microbes (as something other than a curse from god)?

There could even be macroscopic lifeforms moving so quickly that we are unable to see them.

So the answer, as far as I can tell, is really that it depends on the kind of life we're referring too.

And if it's too far outside the human context of understanding or perception, then the answer is no.
Earth has been through similar changes too. Life started in water, a "low gravity" environment, then moved onto land. Similarly, the atmosphere was initially very oxygen saturated, causing animals to be very big. Declining oxygen rates in the atmosphere caused animals to converge to a smaller size. But, we don't see extreme differences when you compare animals from millions of years ago to today despite that the ecological parameters have changed significantly.
I think the LLMs are better if you want knowledge synthesized, assuming it can be done correctly (it is very confidently wrong a lot of the time). But if you’re trying to find something specific, often you want the complete work published by a human as is.
