JimmyAustin··on GoPro warned it may not survive
As a diver, if you jump into moderately warm water (the Great Barrier Reef for instance), that won't save you either. Mine overheats and dies after 15-20 minutes. It took diving near Seattle to keep it going continuously.
JimmyAustin··on What If Heavy Files Felt Heavy?
You might have to mess around with the software to figure out the details, but from a hardware perspective a hall effect keyboard should be at least able to infer the speed a key is travelling at when bottoms out.
JimmyAustin··on AI agents find $4.6M in blockchain smart contract exploits
There are a great many of them, you just can't see them in the dark forest. https://www.paradigm.xyz/2020/08/ethereum-is-a-dark-forest
JimmyAustin··on After nine years of grinding, Replit found its market. Can it keep it?
Hey, Replit employee here. I'm pretty sure this isn't us (definitely isn't our marketing team's MO AFAIK). Can you email me some examples at james @ replit dot com so I can look into this?
JimmyAustin··on List of Countries Without a Value-Added Tax
It reduces the degree of regressive, but as long as lower-income people spend any money at all on nonexempt goods it will never make it neutral.
JimmyAustin··on List of Countries Without a Value-Added Tax
GST and VAT are the same thing, different countries just call them different things.

As an example, GST in Australia is in the price on the shelf. You can also claim back the GST you paid on your input goods, which means you effectively pay the difference on the GST your customers pay you, and you paid your suppliers (which is the value added!).

JimmyAustin··on Nvidia's RTX 5090 power connectors are melting
FWIW, I had the same issue with my 3090 (though I believe that uses a slightly different port?). I was using a custom cable like this guy. Nvidia replaced it under warranty, and I went back to using the (ugly) provided adapter.
JimmyAustin··on Anthropic Chief Says AI Could Surpass 'Almost All Humans ' Shortly After 2027
> they are assistants. They aren’t inventors or prognosticators. They cannot predict how the market will react to a product or idea.

Can you?

JimmyAustin··on Geico terminating insurance coverage of Tesla Cybertrucks
TLDR: If he buys a car a year, and drives the same number of miles as the average American, his total emissions are probably equal to someone who drives 28k miles a year.

Carbon emissions for a Model 3 vs a Toyota Corolla even out after 13'500 miles according to Argonne National Laboratory [1], which is slightly less than the average an American drives per year (14'263 miles [2]). Assuming that he drives as much as the average driver, his cars generate as much Co2 as a Model 3 (definitely not true for the Cybertruck, but he probably has low-build-emission ICE cars in the other 8 to lower the average), and he buys a car a year, he has roughly the equivalent emissions of someone who drives twice the average number of miles each year. For reference, a long haul driver (of which there are 300k-500k in the US [3]) drives 100-110k miles [4] a year (7-8x the average).

JimmyAustin··on Scientists rename genes to stop Microsoft Excel from misreading them as dates (2020)
A lot of analysis is done using CSVs being pushed in and out of Excel. Doing so strips the formatting. Please understand the workflows being crying “skill issue”.
JimmyAustin··on AI Restaurant Menu with RAG
The model they use (BAAI/bge-small-en-v1.5) produces embeddings 384 wide, at float32 that equals 1536 bytes each. The size of all the vectors for 100 items is 153kb. Calculating the dot product of that against a query will be under measured in nano seconds, even with a naive implementation.
JimmyAustin··on One-Pedal Driving Explained
That is exactly how one-pedal driving in a Tesla works!
JimmyAustin··on How to unit test code that depends on time
The function you pass in can keep track of how many times it’s been called, and provide different values on each call.
JimmyAustin··on 'Safe' alternatives to engineered stone bench tops may not be so safe: study
This is the Australian Broadcasting Corporation's website (the Australian national broadcaster a la the BBC). As a whole coverage is pretty good, but the website has gotten more clickbaity in recent years.
JimmyAustin··on Ask HN: CDK vs. Terraform – which one do you prefer and why?
CDK for Terraform (https://developer.hashicorp.com/terraform/cdktf) is the best of both worlds. We've been using it at Replit with great success.
JimmyAustin··on Replit permanently moves to paid hosting after 7 years of free service
We actually announced that Ghostwriter is now free for all users last week: https://blog.replit.com/ai4all. The free tier is using a smaller model for chat than the paid version for cost reasons, but it has all the same integrations (inline suggestions/code transformation/etc).

(Disclaimer, I work at Replit on the AI team, but don't represent the company)

JimmyAustin··on Intel shows 8 core 528 thread processor with silicon photonics
Apple left for TSMC, not to do in-house chip fabrication.
JimmyAustin··on Wikipedia-grounded chatbot “outperforms all baselines” on factual accuracy
That isn't what is being described here. They are just providing additional context to ChatGPT using its plugin API. It's still trained on large amounts of public text data.
JimmyAustin··on Missing Titanic sub faced lawsuit over depths it could safely travel to
I'd say it's more "doesn't bother to tread" rather than "doesn't dare to tread". There probably is not a lot below 1.5km that would be of much interest to the US Navy.
JimmyAustin··on OpenAI Employee: GPT-4 has been static since March
GPTs are not trained on themselves, and what little knowledge they have of their own capabilities is limited to the discussion of it in their training set. This is a hallucination.
JimmyAustin··on World of Goo Remastered
This is most likely lawyer CYA, rather than any real attempt to stop kids from playing games. Is it absurd? Yes. Is anyone going to have any issues with it? No.
JimmyAustin··on BLOOMChat, a 176B parameter, Multi-lingual, fine tuned chat
LLMs being bad at math is a known issue, but what they are good at is writing programs. For example:

>>> Write a program that calculates if 120 is greater than 0.7.

>Sure, here's a program in Python that calculates if 120 is greater than 0.7:

    if 120 > 0.7:
        print("Yes, 120 is greater than 0.7")
    else:
        print("No, 120 is not greater than 0.7")
For straight input/output like what this model is trained on, questions like this don't work well. However if LLMs are equipped with tools (like a code interpreter), they get a lot smarter.
JimmyAustin··on Big Tech Resumed Hiring Foreign Workers Just Weeks After Layoffs
Immigrants subsidize the citizenry. They pay enormous amounts of taxes, and consume no welfare.
JimmyAustin··on Big Tech Resumed Hiring Foreign Workers Just Weeks After Layoffs
By that logic babies are bad for workers, they grow up and take their jobs!

Except that is obviously ridiculous, because people on visas induce their own demand in the local economy, growing the pie for everyone. They are also pre-trained, commit crime at a level vastly below the citizen population, don't get any sort of welfare, and pay enormous amounts of taxes.

JimmyAustin··on Fairbuds XL review: noise-cancelling headphones you can fix
+1 to the Wicked Cushions suggestion. The pads on my Bose 700s split, and the Wicked Cushion replacements were thicker and had better isolation than the OEM pads. They seem to have held up really well over the last 12 months as well.
JimmyAustin··on Internet disrupted in Pakistan amid arrest of former PM Imran Khan
The likelyhood of a decentralized constellation of low orbit satellites ever existing is next to zero, and having additional internet connectivity options can never reduce availability. Sure corporations and governments are both corruptible, but if both are available, and neither can impose on the other (I don't think Pakistan has much of a say in how SpaceX runs StarLink, and SpaceX doesn't have a say in Pakistan runs Pakistan), the existence of another option is good.
JimmyAustin··on Internet disrupted in Pakistan amid arrest of former PM Imran Khan
You are describing StarLink once they get laser-based relaying between satellites working.
JimmyAustin··on Ask HN: World building game to play with my father (63) online
+1 for Factorio.

As alternatives, there are Satisfactory (which is 3D and prettier than Factorio, but not as polished), and Dyson Sphere Program (which lacks multiplayer).

JimmyAustin··on Apple Pay’s long road to paying off is getting shorter
The physical Apple Card itself doesn’t even support contactless payment, it needs to physically be swiped or inserted.
