You are paying the smartest people in the world to think really really hard, and turns out they might also think really really hard about not making the world a worse place

I'm curious - what were you doing that polars was leaving a 40-80x speedup on the table? I've been happy with it's speed when held correctly, but it's certainly easy to hold it incorrectly and kill your perf if you're not careful

You can't seriously claim points 2) and 3) if you've ever actually paid for and watched cable

> Unless of course you need aerospace or space-qualified screws in which case they are definitely coming from the US.

Are you claiming somehow that China would be incapable of making these? Or just admitting that the USG generally restricts such contracts to be sourced from the US only? And what does this have to do with Apple?

iPhones have had lidar for years, have cameras been affected?

New comment by ladberg in "Data centers in space makes no sense"

I'd assume Starlink satellites do the minimal possible amount of compute required (thus power used, thus heat generated) to provide service. The builders of data centers are hungry for as many watts on Earth as they can source.

New comment by ladberg in "40 percent of fMRI signals do not correspond to actual brain activity"

ladberg — Wed, 17 Dec 2025 05:02:43 +0000

The study misleading claimed to produce images from brainwaves. In reality, they effectively built a combination of classifier from brainwaves to one of a few predetermined classifications of images shown (still cool, but less impressive) and a neural net to reproduce images it was trained on given a classification (boring).

Apple is the leader of nearly all new developments to the ARM ISA, which has evolved considerably since Acorn died.

New comment by ladberg in "Smartphone Cameras Go Hyperspectral"

They're not claiming to get that many values per pixel, they're getting that many values overall for the medium through which light passes between the card and the phone. The idea light comes from a source (e.g. sun), bounces off the various colors of the card and thus produces hundreds of different spectra, those all pass through a medium, and land on the phone camera. So you're getting one measurement consisting of hundreds of RGB values that each represent intensity of different spectra, and you combine it all together to get a single spectrogram.

Given that the compiled version is slower than then eager version on A100, there's definitely something suboptimal happening there

I think you're misunderstanding what that page is: it's not an advertisement to invest with the company, it's an advertisement to trade via/with the company in the same way you might otherwise go manually trade from a Bloomberg terminal (or any other method).

There is no way to invest in the company, and the only way of becoming a "customer" is to engage in trading.

> Its a finance firm - i.e scam firm. "We have a fancy trading algorithm that statistically is never going to outperform just buying VOO and holding it, but the thing is if you get lucky, it could".

HRT trades their own money so if it didn't beat VOO then they'd just buy VOO. There are no external investors to scam.

I can't comment on whether these particular pieces were generated, but models are certainly good enough now to handle these cases and more

This strategy by definition wouldn't work if it was "background noise" because it relies on being able to move the market

The main release highlighted by the article is cuTile which is certainly about jitting kernels from Python code

It doesn't claim it's possible now, it's a fictional short story claiming "AIs can do everything taught by a CS degree" by the end of 2026.
