Although the article is intimidating, the implementation appears pretty simple and flexible. Has anyone tried using this either in the Darktable app or in their own libraries? I might like to try porting it to JS to compare it for web based

With latest LLMs I feel there is less and less need to be structured about authoring recipes. I now jot down rough notes in Obsidian when I make a meal I like, and let AI re-format it if I want to share the full recipe with somebody. This a

Good idea – but it will probably take even longer than wiping with a paper towel.

That’s the kind of re-seasoning I mean: first I dry it (paper towel), then wipe with oil (more paper towel). It’s more work than cleaning a nonstick by hand and produces more waste.

I love my cast iron, but usually choose a nonstick for eggs and crepes/pancakes in the morning. - I tend to re-season my cast iron every time I use it and it’s a chore to do this for my early morning meals. - Non-stick is just more non

I’m not sure I’d call Figma local first. If I’m offline or in a spotty wifi area, I can’t load my designs. And unless it’s recently changed, if you lose wifi and quit the browser after some edits, they won’t be saved.

I’ve implemented[1] some of these algorithms into @texel/color, a modern JS color library, and it also supports gamut mapping to certain wide gamut color spaces (Display P3, Rec2020, Adobe 1998) rather than just sRGB. https:/&#x2

Not quite—you can choose a ramp that will remain in-gamut for sRGB, eg try shifting hue here: https://oklch.com/#72.67,0.121,240.19,100 Even if you were to use a more saturated ramp, I suspect that discontinuities due to ga

Pure RGB primaries gives an easy target for “red” and “green” endpoints but that’s about it. Ideally the test should consider two endpoints with uniform lightness and chroma, and just shift the hue to form in-betweens. The transition from b

Surely this should be using a perceptually uniform color space like OKLab rather than HSL!

To play devils advocate: - if your app has a number of messages (eg: “image downloaded” or “message sent” or whatever) then there is a consistency in using toasts as they all appear in the same predictable manner - often “appear away from f

Really fascinating. After reading a little more, I learned that while Laine proposed the inversion layer hypothesis in 2016, the Auroral Acoustics group he headed was informally started in 2000. The reason the linked article is coming out n

For the “terrain contours” is there something specific you’ve done to make it feel more cartographic? Or is it basically just marching cubes / iso lines on some data points? Looks fantastic. Very cool project.

Looks great. How are you encoding the video into MP4? Ffmpeg with wasm? Or WebCodecs? I’ve struggled to find a pure client-side encoder that is as fast, lightweight and high quality (in terms of lossiness) as what I had going with mp4-h264[

Looking forward to using this. Curious about how far away WebGPU/WASM support might be, it could provide a single cross-platform backend.

Digital ID that I’m describing would be a way to avoid the current awful status quo of uploading your passport online (which, in the UK, has become common for things like banking, immigration, and other services). I’m not sure what your i

having a cryptographic government-backed digital ID could really be a great and privacy-preserving feature of modern society. for example: ZK proofs are now practical, and could improve upon the status quo of sending a digital JPG of a scan

In Sweden they sell bucketloads of saffron for basically a euro or two per pack. The equivalent in UK stores would have a 10x markup at least. It seems like an industry that somebody could easily capitalize on, unless there is some trade or

You are right. I was mistakenly thinking that the alternative (naive approach) would be to write the promise-creating tasks within the for loop, but if they are not part of the loop, the functionality is basically equivalent to Promise.all.

by mattdesl 3y ago
To do parallel tasks in a loop for the situation I outlined (getting a final array of images from URIs), it would be really cumbersome, and your implementation would be pretty much equivalent to the inner workings of Promise.all. As others

by mattdesl 3y ago
I often map a series of X to Y with Promise.all. For example, mapping a series of image URIs to loaded Image elements. It is shorter to write than a for of loop, and importantly, all images will be loaded in parallel rather than sequentiall

Lots of that advanced math research finds its way into practical engineering (cryptography, digital media, compression, physics, AI, and so on). The average layperson does not care about mathematics, period. You may see a similar situation
