meltyness··on Tighter bounds on the expressivity of transformer encoders
Does this mean that transformers are most akin to rule-based expert systems with opaque (currently) statistically-devised rules?
meltyness··on Congress gets 40 ChatGPT Plus licenses to start experimenting with generative AI
An easily-verifiable garbage-generation resource!
meltyness··on Ask HN: Is prompt engineering just snake oil?
Yes, we would all prefer "philosopher of corpus-linguistic preference membranes, and domain-specific knowledge manager" because it's more precise, and doesn't trample on my position/salary/pedigree.

Let's estimate that it's current input limit is 20 or so paragraphs, and that it's capable of zero-shot learning as observed by many of the experimenters on the system.

For every 20 paragraph thesis about the world around us, how often do you think someone meaningfully innovates and changes meaningfully our understanding of the world around us, and it's fundamentals?

Consider, like, classical logic. It's pretty much done. You have the universal gate sets, and any novel functions are just going to be an mxn-mux. Most other such general concepts are essentially figured out and have had their applications recorded, explained, demonstrated.

Sure, biographical information and history changes on a whim, but no one is requesting artificial clairvoyant intelligence.

I suppose you could have the model pontificate and assess the truth of its own argumentation (ask it to generate outer-product concepts, ask it to reassess assumptions in current models) but it will quickly learn its own language that will be mutually unintelligible with the corpus of current human knowledge it has been trained on.

Why does the underlying model need to change on a whim, in your opinion?... on what whim?

Please describe what you mean by "an online processing model of any kind"

... not that I don't disagree with the rest of what you think you've said here, but I think that this part of your claim is egregiously paucious.

I like it for some stuff. The UI is certainly faster than ChatGPT, and seems to be more reliable at this stage. I suspect that its training has benefited from the unique corpus access relationships Google has accumulated since it's pre-IPO heyday. Think of the data connections they were establishing around 2005 with the establishment of Google Video and Google Books.

meltyness··on Ask HN: Attend a post-baccalaureate CS program or double down on self-study?
I would say that a B.S. is most useful when you don't want it -- the curriculum is like an "averted vision" phenomena where it is most valuable when you're not focused on its application -- especially for example that it is a pre-requisite for many positions.

Check with your school's career center and seek an internship. Success at an internship and maintaining a quality career track is one way a B.S. is extremely valuable.

The other way a B.S. is valuable is networking and making groundbreaking moves -- startups with talented peers or research with guidance from talented professors -- while you're pursuing the degree.

Think of the degree at the end as a hedge for your access to any of those tracks and you'll be better served.

meltyness··on Avoid using free public phone charging stations, FBI Denver warns
In other news, phones have a visible interface called the "USB port," and it transfers data in addition to charging the phone. Wow!
meltyness··on Ask HN: What questions do LMMs fail with?
Character-level manipulation fails. I suspect this is because GPTs are trained on tokens rather than sequences of characters, means they're fundamentally dyslexic and can't really spell.

meltyness··on Frank founder allegedly defrauded JPMorgan out of $175M hit with federal charges
JPM is in private equity? That's concerning.
meltyness··on Ask HN: Is "Stop Writing Classes” still good advice in modern Python?
Another meaningful consideration is whether or not you intend for the project to remain python for it's full lifecycle.

If you're looking forward to porting to a more performant language, dict has parity with struct, and vtable dereferencing and polymorphism has performance penalties in say, C++. rust and golang don't really have a robust object implementation so flatter structuring is preferred.

meltyness··on Pause Giant AI Experiments: An Open Letter
If you're cynical and paranoid enough, you might suspect environmentalism is entirely a smug way to discuss culture and exclude people, a sort of verbal dollhouse for gossip.

meltyness··on The sad state of U.S. life expectancy
Shockingly, it's drug overdoses.

Apparently copious unfulfilling underpaid labor may lead to escapism. Simultaneously we're exporting inflation to our southern neighbors who have a robust, lucrative industry which may lead to conditions favoring that fate.

meltyness··on Bitcoin is a solution looking for a problem
But that's another illusion mirroring the banking structure -- fractional reserve -- that some 90% of your assets should be generating rent, and 10% in reserves.

If banks pick winners, everything becomes a bank.

meltyness··on Bitcoin is a solution looking for a problem
I'll give that it's reductionist, but that's kind of the point. Loans are investments, securities often are too as keys to liquidity and creditworthiness. Money is money, I'm not contesting that.

The question no one asked is if everything should be stockpiled.

I think there's no question that we should make things better or more plentiful.

meltyness··on Bitcoin is a solution looking for a problem
I hate to walk into proselytizing but:

I mean if your intent is speculation, this is how the rest of the internet has been built.

TCP and OS security are so bad they ripped the internet a whole Cloudflare, but they all still exist and find their uses in real systems.

No comment on regulatory or legal frameworks in place since I have no idea what's gone on in the courts on that front. It's like entropy though and I have doubts that there's any long term value in trying to stop it.

Banks beget banks, because banks only invest in diversified quasi-banks, basically stockpiling non-cash assets, feast or famine. A reasonable structure for much of human history, if you like (often) dry, safe, grain/peas in the winter. Before global transport was fast and risk-free. In vogue right now: "all the PCs, all the business software, all the electrification efforts/grid modernization, all the goods manufacturers storefronts, all the films, all the personal sites, all the web pages." Maybe not such a relevant capability (large stockpiles) outside of, well, contingency.

Bitcoin, the machine, only invests in progress, cheaper more plentiful energy and faster processors or you lose. It has scarcity and inherits supporting stockpiling.

Ethereum? Presumably cooperation and transparent software, also good things! Perhaps in the next century proof of health, proof of satiety.

meltyness··on Reasons the banking crisis isn’t a repeat of 2008
Crypto is diffuse and not very many people. Fewer than 2M bitcoin wallets contain $28K, a median family's worth of savings / 4 checking accounts.

That's not even a whole city's worth of people "demonstrating", and it's a global thing. It's a quarter of the speculative value of AAPL.

It's also concurrent and passive. Very few people have dropped everything to do the crypto influencer dance, and now influencer+crypto is seeing SEC crackdowns.

Crypto is at most slacktivism right now. Nothing like BLM, MAGA, which are no doubt viewed by powerful economic planners as wasteful.

meltyness··on “Can we ban iPhone in retaliation?” Chinese internet reacts to TikTok hearing
I haven't watched the TikTok hearing, but I have watched the 4-5 preceding Big Tech-focused hearings basically since "The Encryption Tightrope."

You can't generalize the whole thing as spectacle just because a few of the congressmen choose to grandstand / push an agenda / be generally tonedeaf, I can almost guess that in 6 hours at least some of the concerns are legitimate and merit public discourse even if they are nuanced, possibly quite boring, and have more to do with how OS maintainers and parents should behave.

Everything is in the crosshairs and nothing material is sacred, and it has been that way for as long as I can remember[0]. That's why we hire these people.

meltyness··on Reasons the banking crisis isn’t a repeat of 2008
Where's the "occupy movement"? Where's the "CHAZ/CHOP" of 2023? What about "hope"? Are netizens signing up for exorbitantly expensive new services on a widespread basis?

If individuals aren't being "excessively enriched" by conditions it's unlikely to become another spectacular market wide blow-up.

Social causes are a proxy for froth. A short Friday memo probably isn't.

Exuberance is in the hands of price gougers right now, and even that's mostly confined to California,... and eggs.

Sure we're back to "grocery delivery" (which marked the height of the .com bubble) but it's the biggest players involved, the technology is practically free these days, and the immunocompromised benefit!

Communication requires two parties, through what other channel is the entire US public to formally express it's concerns to the company?
meltyness··on “Can we ban iPhone in retaliation?” Chinese internet reacts to TikTok hearing
I mean, civic engagement is certainly a cultural difference, and it's pretty stark I think.

I can remember being in high school, still in the age of minority, and feeling joy when one of the louder, dumber cooks finally kicked off.

I kind of suspect Beijing and the CCP of not being so colorful at the federal level, and rather just being a giant executive bureaucracy with principle, law, and regulation intermixed freely, minimal federation, which leaves them largely ignored by society and festering until they're in your face enforcing lock downs -- like an authoritarian military state.

I unfortunately don't read a lick of Mandarin, and I'm not sure where to get a more optimistic view about what goes on over there, but I'm curious.

meltyness··on “Can we ban iPhone in retaliation?” Chinese internet reacts to TikTok hearing
6 hours of testimony that, at most, 2-3% of the country even glanced at is a spectacle in your eyes?

This looks like splitting, or you're deliberately failing to understand how lawmaking works and the importance of making informed decisions at the federal level, in the long term.

Congress constantly grills CEOs, the elite, and victims because it is understood that they reshape society, sometimes for the worse, not always on purpose.

Is a law needed? How do we tax it? Who is being harmed? What is the harm? Can a law be enforced?

The transparency is by default. Not a "spectacle".

meltyness··on Google Chrome Comic
I saw this in it's day. I respect how much optimism they mustered. Really.
meltyness··on Reasons the banking crisis isn’t a repeat of 2008
To summarize:

  "Policymakers have tools to solve banking crises [...]"
With TARP/EESA still in place Fed/Treasury have more power

  "The economy is in a much different place"
XLK has subsumed XLF since 2008

  "The magnitude of the problem is, so far, much smaller"
Look forward to my upcoming essay "Casting doubt on the commercial real-estate economy"

In conclusion, "we still don't see it coming" avoiding the term, "subprime" or acknowledging that predatory lending ever occurred, and this weird typo:

  "[...] the primary facility *though* which banks can borrow [...]"

meltyness··on Simplest thing GPT4 can’t do?
I mean, from the structure of things that makes sense.

If you think of it as a statistically-derived processor/algorithm, unless there's some great task of short-term memory/memorization it's forced to undergo it's going to be biased towards more direct responses.

Another thing to consider, regarding the fine-tuning, is that "instruction" may be biased towards sentence ordering, so that the actual order with which you present your prompt can be important.

For example Prompt: <detailed situational specification>. <task to be performed> might perform considerably worse than <task to be performed>. <detailed situational specification>.

I suspect it's just a short-mid-term resource constraint though since:

- demonstrating extremely sharp memory performance conversationally isn't that common

- total bout / token width isn't particularly wide in training

- presumably fewer "transistors" than humans -- basically even 200B parameters isn't all that many

Another concern that I'm not sure how to consider is that 4-letter tokenization could be an obvious reason ChatGPT is such a poor speller.

The emoji favicon is not reassuring to me about the attitude towards the product.
