declaredapple··on Ask HN: What is the best site to track eclipse weather predictions?
Some people may be willing to travel but don't know where the best place to go is.
declaredapple··on OpenAI: Start using ChatGPT instantly
It's going to be GPT-3.5turbo not GPT4. As others have mentioned, binggpt/bard are also free.

These smaller models are a relatively cheap to run, especially in high batches.

I'm sure there will also be aggressive rate limits.

declaredapple··on Towards 1-bit Machine Learning Models
They've been designing their own chips a while now, including with an NPU.

Also because of their unified memory design, they actually have insane bandwidth which is incredibly useful for LLMs. IMO they may have a head-start in that respect for on-device inference of large models (e.g. 1B+ params).

declaredapple··on 'Noisy' autistic brains seem better at certain tasks
I think there's clear social impairment. Making friends is harder and it takes more "manual" effort to socialize "effectively".

However much of this social impairment may or may not be a real problem. "special interests" and "obsessing over one topic" is an impairment in social scenerios, but can be extremely beneficial for tasks related to that special interest.

The irony in this is magical.

I highly suggest you remarket as a collection of some type of link a la product hunt. Tech startups, cool apps, anything.

"backlink service" is literally just "seo spam" on it's own.

declaredapple··on Advances in semiconductors are feeding the AI boom
> companies like OpenAI have had access to large quantities of H100 for a few months now and Sora is being presented

From what I could tell from Nvidia's recent presentation, Nvidia works directly with OpenAI to test their next gen hardware. IIRC they had some slides showing the throughput comparisons with Hopper and Blackwell, suggesting they used OpenAI's workload for testing.

H100's have been generally available (not a long waitlist) for only several months, but all the big players had them already 1 year ago.

I agree with you, but I think you might be 1 generation behind.

> OpenAI used H100’s predecessor — NVIDIA A100 GPUs — to train and run ChatGPT, an AI system optimized for dialogue, which has been used by hundreds of millions of people worldwide in record time. OpenAI will be using H100 on its Azure supercomputer to power its continuing AI research.

declaredapple··on DBRX: A new open LLM
What?

Are you asking if the framework automatically quantizes/prunes the model on the fly?

Or are you suggesting the LLM itself should realize it's too big to run, and prune/quantize itself? Your references to "intelligent" almost leads me to the conclusion that you think the LLM should prune itself. Not only is this a chicken and egg problem, but LLMs are statistical models, they aren't inherently self bootstraping.

declaredapple··on Claude 3 surpasses GPT-4 on Chatbot Arena for the first time
For me GPT4 seems to suggest more generic unittests in python. They're much more "Put tests here", or "path.to.dependency".

Claude3 opus (and often Sonnet) actually fills in the full dependency paths, actually makes tests, and just overall seems to "know what I want from it".

declaredapple··on DBRX: A new open LLM
> you do not divulge details of your training data.

FWIW asking LLMs about their training data is generally HEAVILY prone to inaccurate responses. They aren't generally told exactly what they were trained on, so their response is completely made up, as they're predicting the next token based on their training data, without knowing what they data was - if that makes any sense.

Let's say it was only trained on the book 1984. It's response will be based on what text would most likely be next from the book 1984 - and if that book doesn't contain "This text is a fictional book called 1984", instead it's just the story - then the LLM would be completing text as if we were still in that book.

tl;dr - LLMs complete text based on what they're trained with, they don't have actual selfawareness and don't know what they were trained with, so they'll happily makeup something.

EDIT: Just to further elaborate - the "innocent" purpose of this could simply be to prevent the model from confidently making up answers about it's training data, since it doesn't know what it's training data was.

declaredapple··on Will PostgreSQL ever change its license?
> But the biggest reason why PostgreSQL would not change its license is the disservice it would do to all PostgreSQL users. It takes a long time to build trust in a technology that is often used for the most critical part of an application: storage and retrieval of data

> Changing the license of PostgreSQL would shatter all of the goodwill the project has built up through the past (nearly) 30 years.

I love Postgres and I have no reason to think they would change their license. But IMO any type of "it would be a disservice to users" is useless. This blog post itself is in response to Redis changing their license after 15 years. Surely this would be a disservice to their users?

Businesses have proven time and time again - They will absolutely cause a "disservice to users" or "harm the product" once money is involved.

Again I recognize the way PostgresQL is structured gives me hope this wouldn't happen, but a simple "we wouldn't break user trust" is meaningless.

declaredapple··on NASA is struggling to compete with Bezos, Musk and their 6-figure salaries
> NASA, which follows the federal government’s General Schedule pay scales, offers starting salaries along a range that starts at $54,557 for engineers with bachelor’s degrees, $66,731 for master’s degrees and $73,038 for doctorates at the Kennedy Space Center in Florida.

I know people likely want to join NASA for more than the salary. But that's brutal.

Heads up that tickets generally don't guarantee the plane you'll be on, they can change at any time for a bunch of different reasons.
declaredapple··on AMD tinybox on hold until we can build and run the relevant firmware on our GPUs
AMD desperately needs to improve their software situation.

It's been like this for 10 years - they have competitive hardware in many cases - but the software is always a buggy mess.

Unfortunately it has caused the situation to be "if you don't want a migraine just use CUDA" for many, many years. Even now they still have issues.

declaredapple··on Garnet – A new remote cache-store from Microsoft Research
I assume it's similar to the 1 billion row challenge with java - C# and Java have sufficiently advanced VM's that they can compete with C/CPP performance - assuming you go out of your way to optimize for it.

declaredapple··on EPA bans asbestos, a deadly carcinogen still in use decades after partial ban
I think that happens because talc deposits often contain asbestos so it's not an uncommon contaminate.

that doesn't mean talc products always contain asbestos

declaredapple··on Alberta allows "Software Engineer" title for non-registered professionals
I'm not completely disagreeing.

But it is one of the few "engineering fields" where many of the top performers don't have degrees or formal educations.

It would be a shame to gatekeep devops engineers with leet code exams for example.

declaredapple··on ChatGPT denies then affirms it generated the text
Is this a question or a statement?

All ChatGPT does is predict the most likely next token (with a little sampling on the top most likely tokens).

That's it.

It doesn't lookup whether it wrote it before, it doesn't use an watermarking tools to check, all it does is predict the next most likely token after the tokens you sent it.

It can't even fill in text in the middle, they have to use a special trick where they have a <filltexthere> token.

It's been finetuned/trained with text that it's generated since it's been all over the internet since it's launch. However I highly doubt it's been tuned to detect chatgpt text (instead I imagine they'll make it opt to use a tool and use a watermarking tool when they eventually do implement it)

You just happened to find two cases were it says yes or no.

You should not expect any accuracy from asking it that question.

declaredapple··on Weather forecasts have become more accurate
Dark sky used to be accurate almost to the minute for me.

Apple Weather will tell me it won't rain today or all week.

Meanwhile NOAA will tell me I'm currently in a thunderstorm and that it will rain all week - And it was right.

Carrot is nice because you can switch between several providers.

declaredapple··on Weather forecasts have become more accurate
What the actual crap did Apple do to mess it up so bad then?

Switching between providers on Carrot, Apple Weather often doesn't predict any amount of rain for the entire week, meanwhile I'm soaked in water in a thunderstorm, and NOAA and others predicted rain the entire week (which it did).

declaredapple··on List me AI models that I can run with my hw?
Take # parameters and divide by 2 and then add like 1 to estimate it for 4bit quantization. A 13B model will need ~7GB of memory at 4bit.

Most quantization models start falling apart rapidly after 4bit, but you can go lower...

If you can fit it in GPU memory it'll likely be usable, if you can't fit it in memory be prepared for single digit t/s or less, the only exception is for people with M1/M2/M3 cpus.

declaredapple··on Plasticity: CAD for Artists
I need to give FreeCAD another try,

but last time I tried it I couldn't figure out how to do almost anything. Fusion 360 and solidworks (and I think onshape) all just "made sense". Throw down a sketch, extrude some surfaces, etc. FreeCAD was a struggle for me and I went back to fusion 360 mostly because I was already familiar with it.

declaredapple··on Plasticity: CAD for Artists
Oh I need to try that addon.

I've been meaning to look for a Fusion360 alternative that can run on linux and doesn't cost $$$$/yr.

declaredapple··on Why is everybody talking about Groq?
The reason for the SRAM according to them,

> If you want low latency you have to be really careful with HBM, not only because of the delay involved, but also the non-determinacy. One of the huge benefits of our LPU architecture is that we can build systems of hundreds of chips with fast interconnect and we know the precise timing of the whole system to within a few parts per million. Once you start integrating non-deterministic components your latency guarantees disappear very quickly.

declaredapple··on "AI, no ads please": 4 words to wipe out $1T
I looked through the article, I don't think this mentions AI+ADs. A lot of this assumes that ai will "directly show us what we're looking for".

But I don't think this is the case. You can easily imagine a query for "What's a good bike to use for [xyz criteria]" returning an injected "Oh you should try XYZ brand bike!"

There's so many ways to go, from avoiding mentioning competitors, showing preferable stats, not mentioning bad reviews, etc.
