Timing. A megabyte of "sleep 10;" would be read from the server more slowly when piped to bash versus written to a file
I feel that AI
does have individual taste (and even "personality"), but it's the same monotonous individual taste across all instances of the same trained AI. The sheer scale of its repetition turns it into a hated trope: like how we can immediately identify slop writing, diagrams, websites, etc.
I'm sure we've all met someone who has a unique speaking style and might repeat phrases or words unusually often, but that still doesn't bug us as much as "the honest truth.." or "load-bearing.."
Just glancing I would say it seems a bit different.
I haven't tried on macos, but yeah, the biggest problem right now seems to be implementation differences with how embedded spaces are handled. Earlier, the biggest cross-browser issues were pixel alignments within the QR codes, but those seem largely resolved.
Some details of how it works are in
https://github.com/jimparis/qr-font/blob/master/design.mdFair warning though: this was designed and implemented by an LLM, as an experiment to see if it was possible. I only guided it to a working solution by pointing out problems, and never dug deeply into its inner workings.

In the "Libre Barcode Project" discussion yesterday, 1bpp asked: "Is anyone willing to sacrifice their sanity for the sake of implementing a QR renderer as TTF hinting code?"Yes. I had some tokens to burn and was curious... turns out, it's possible. This was put together by a mix of Gemini, GPT, and Claude (depending on which usage limits kept running out).
It is not a tricky problem because it has a simple and obvious solution: do not filter or block usage just because the input includes a word like "gun".
My dad wears smart glasses because he's nearly deaf and the classes show captions for the person he's talking to. They're great. He doesn't use or care at all about the camera. Having the captions would be very useful to him in a courtroom setting. Collateral damage I guess.
It's not enclosed in the final product. It is used during manufacturing. For example, you mechanically compress helium to get liquid helium, then when it depressurizes back to ambient pressure, it's -269 C, which is pretty close to "as cold as possible", and colder than any alternatives.
Yeah, everyone learns differently, but for me this is a perfect way to better understand how GPTs work.
> > some folks want to use lossless cut
> In that case I would encourage you to ruminate on what the following in the post you're replying to means and what the implications are:
You may have misunderstood the comment: "lossless cut" is the name of an ffmpeg GUI front end. They're not discussing which exact command line gives lossless results.
200mg/day is not a "very very small dose". FDA recommended maximum safe amount is 400mg/day.
I was curious what the protein picture was showing:
"Figure 1 Example predictions of SimpleFold on targets ... with ground truth shown in light aqua and prediction in deep teal."
and now I'm even more curious why they thought "light aqua" vs "deep teal" would be a good choice
Zuck owns 13% of Meta shares and 61% of the voting power
Jensen Huang owns 3.8% of Nvidia and 3.8% of the voting power
Tim Cook owns 0.021% of Apple and 0.021% of the voting power
Previously, Steve Jobs owned 0.6% of Apple and 0.6% of the voting power
So yeah, there's a structural difference here and Meta is much closer to being owned, managed, and controlled by Zuck alone
I don't know (and don't need you to elaborate on) exactly what you're referring to in that last sentence, but I suspect you are confusing Eric W. Weisstein with Eric Weisstein.
Lazy, or more efficient? If you type a time and hit start, you're not microwaving until you're done with all the buttons. If you hit "QS" a bunch to reach the duration instead, the microwave starts cooking immediately on the first press. Your nuggets get done a whole second earlier!
Relative to the handedness, one bolt is always moving with it, one bolt is always moving against it. Switching direction doesn't change that. So switching direction can't change whether it moves inward or outward.
Switching the direction that you're twiddling the bolts would have to change the direction of any movement. But by symmetry, clockwise and counterclockwise twiddling are identical (looking down on the head of each bolt, one is always moving clockwise and one is always moving counterclockwise). So there must be no in/out movement at all.
some math because I'm curious:
If you draw down and replace 50% of the water every day, each molecule has a 1/2 chance of sticking around.
After 3 months that's 1/(2^90).
A 5 gallon pot contains around 2^87 water molecules.
So after 3 months there's basically none of the original liquid left.
They were screwed from the start...
The Xbox came out when the PS2 did. When it came time for the next generation, Sony went with the obvious PS3. Microsoft of course couldn't compete with an "Xbox 2" vs a "PS3", and they couldn't skip right to "Xbox 3", so they called it the "Xbox 360", which was frankly genius because it had the 3 there anyway and put it on the same level in consumers' eyes.
But after that it all fell apart -- they had no good options. They still couldn't jump to "Xbox 4". Maybe "720" would have worked. Someone decided to have a clean break and restart at "One" but of course that fell apart immediately at "Two". So another clean break to "Series..". And by that point it's so screwy they've lost any chance of fixing it...
If the earth were a point mass than almost any trajectory at all would be orbital.
> This is no good. Let me just try reverting to a version from a month ago. Nothing. Three months ago? Nothing. Still failing. A year ago? Zilch.
Reverting your own code, but still using a broken PostHog update from that same day? For me, the lesson is to make sure that I can revert everything, including dependencies.

That was from Richard Feynman.
https://en.wikipedia.org/wiki/SawStop"An oscillator generates a 12-volt, 200-kilohertz (kHz) pulsed electrical signal, which is applied to a small plate on one side of the blade. The signal is transferred to the blade by capacitive coupling. A plate on the other side of the blade picks up the signal and sends it to a threshold detector. If a human contacts the blade, the signal will fall below the threshold. After signal loss for 25 micro seconds (µs), the detector will fire. A tooth on a 10-inch circular blade rotating at 4000 RPM will stay in contact with the approximate width of a fingertip for 100 µs. The 200-kHz signal will have up to 10 pulses during that time, and should be able to detect contact with just one tooth.[4] When the brake activates, a spring pushes an aluminum block into the blade. The block is normally held away from the blade by a wire, but during braking an electric current instantly melts the wire, similar to a fuse blowing."
The Arduino build system does this (preprocesses your source code to pull out prototypes and put them at the top). To make things easier for beginners.
Maybe the prices were calculated to make post-sales-tax amounts round numbers? That's been the case when I've seen weirdly precise store pricing in the past.
