In git gui, you can highlight a line and right-click to stage or unstage just that line. I just googled it and discovered it’s relatively easy to add a keyboard shortcut for it, but I’m not sure how useful that is.

Git gui does per-line staging, and comes with git…

by dahart 3mo ago
This isn’t partial commits. It’s partial staging. This does not promote committing untested code. Committing also doesn’t promote a lack of testing, there’s no justification for that assumption.

This is very cool, a clever technique to get cubic Bezier evaluation using a single 2D 2x2 bilinear texture sample. (Hi Alan!) I’m not sure I realized that the trilinear diagonal of a cube is a cubic Bezier (but when you say it that way it

There’s a material algorithmic difference between rebuild and refit. Not sure if that point was clearly understood.

Multi-course ouds and lutes of course predate anything resembling the modern guitar by a long, long way. Do you consider those in the “guitar family”? If so, I’d refer to the group as oud or lute family. Guitar family is a recent subset of

What do you mean about more than two octaves? The basic power chord is 3 notes, for example E2 + B2 + E3. One of those is an octave.

Hmm, I’m not seeing what you are, unless you mean ignore all data from Apr 2020 to Dec 2021. It took almost 2 full years for unemployment to return to the pre-covid norm. The spike is immediate in apr 2020, then it falls quickly for 6 month

Ah, you’re right.. the dots! I still don’t understand why the smoothing makes covid symmetric when the underlying data is asymmetric. A too-large smoothing window, I guess. They must have been trying to smooth out the seasonal job unemploym

Hey good! I’d like a good python shell. Does xonsh fix cut and paste with python? The first huge problem I ran into with python shelling is you can’t cut as paste indented code at all. Edit I’m reading about it, here are some notes to mysel

Why does the unemployment chart show a slow rise in unemployment for a year or more before covid started? This does not agree with the data from the BLS, which showed unemployment spiked very suddenly in March 2020. https://www

Which NNs and what tasks are you thinking of? DLSS, for example, reconstructs texture, along with other denoisers, as well as all video models. Are you thinking only of object recognition? Why do you believe training on dithered images woul
108.
by dahart 3mo ago
Gotcha, that’s true. There’s gradations of non-reversible. FFT in practice is still not perfectly reversible, even if you use floats and don’t quantize to 8-bit. Anyway, yeah, dither will be even more non-reversible, but given how good to
109.
by dahart 3mo ago
Perhaps because inference on dithered images is pretty rare, not a common or popular thing to do? Otherwise, people would train on dithered images. NNs are trained on noisy images. Training with dither would not learn any other invariants b

by dahart 3mo ago
That only says to not expect compression from dither, it’s not a counterpoint to using dither for any other reason.
111.
by dahart 3mo ago
Dither loses information, so perfectly reversible might be an unreasonable goal. But I bet you could train or fine-tune a denoiser to do a really good job. This might make a cool paper, if there’s anything at all non-standard or surprising

I don’t think I agree with that at all. Color banding is a problem with NTSC - 540 interlaced, and lower resolutions too. If you have a smooth gradient that shows color banding, spatial resolution is completely irrelevant. Pixelation is a s

by dahart 3mo ago
True! You’re less likely to be surprised by banding on a display, because you can see it before it’s a problem, and it’s less likely to cost money, but for sure the need for dithering is still there, especially for displays that can do more
115.
by dahart 3mo ago
Yeah this is important when you print images, since printers can reveal banding artifacts you can’t see on a monitor. I learned this the expensive way printing a batch of large format images that had gradients in them, without dithering. Th

I’d say halftoning is a specific type of dithering. Wikipedia mentions that for print, some people consider the terms synonymous. https://en.wikipedia.org/wiki/Dither#Applications

You misunderstood me. I was referring to training, not memories. It’s you who is wrong, my friend. It is possible to train on every prompt. ChatGPT is not currently doing that, but it is in fact possible to do.

It’s as if you didn’t read or respond to my comment. LLM models are capable of learning… it’s called training. Models do change during training. You seem to be fixated on today’s inference, perhaps?

They don’t. You’re cherry picking a biased sample. Black kids have “unfortunate” circumstances statistically more often than white kids, and some of that disadvantage stems from when racism was legal and widely practiced. It can take genera
