From my vantage I would argue LLMs make good devs around 0.65x more productive

roblh · 2 days ago

I think they make good devs 2x more productive for the first month, which then slowly declines as that good dev spends less time actually writing and understanding and debugging code until it falls well below the 1x mark. It’s basically a high interest loan people take against their own skills. For some people that loan might be worth it. Maybe they’re trying to change their role in an organization and need the boost to start taking up new responsibilities they want to own. I think it’s temporary though. The slow shift into “skim mode”, where the authors just don’t quite put that same amount of effort into understanding what’s being churned out. I dunno, that’s just what I’ve seen.

Libraries shouldn't log. Just have your top-level abstractions extend an EventEmitter base, emit appropriate events, and let the user do the rest.

This is so simple and makes so much sense. I’ve seen a couple libraries that do something similar, but I feel like this is obvious and useful enough that it should just be a stock pattern, and it clearly isn’t.

Can I ask why it will produce terrible color rendering? In addition to commercial scanners that used narrowband trichromatic (RGB) light sources, hobbyists are creating their own RGB light sources to digitize color negative film claiming superior results and putting forward arguments why this is better:

https://jackw01.github.io/scanlight/

(NB: Most film I shoot is slide film, which I’ve been told doesn’t benefit from RGB light sources because it’s intended viewing was projected with a broad-spectrum white light [likely a warmer than daylight (but color temperature isn’t much of a concern for digitizing slides)] so I haven’t dug into this much.)

I got one of these from the latest batch last week and I’m not entirely convinced by it yet. I need to experiment some more but I went back and did a couple rolls from this summer and so far I think the cslite warm setting + negative lab pro results are better and more consistent. I’m still getting some wonky colour casts with it. It’s nice that the control app lets you change the power of each LED colour separately, so that’s the next thing I’m going to experiment with.

I’ll also note that negative lab pro hates negatives that are scanned with it. They don’t turn out at all. If you’re using it, you should expect to be inverting them manually, which is kind of a pain. I was quietly hoping (but not expecting) to still see some of the benefits of it when passing them through NLP.

You’re for sure exceeding the linear resolving power of 35mm film at 40MP or 64MP.

However, a Bayer-filtered sensor has lower color resolution, since each pixel only sees one color. So the pixel shift really helps quite a bit here since the sensor (and Bayer array) are shifting relative to the film multiple times per exposure.

High-quality film scanners maintain color resolution by using linear sensors without Bayer filtering. But they’re slow and expensive.

All the current Nikon Z bodies (and probably other brands too) have different levels of pixel shift where it’ll take 4 or 8 images and basically cancel out that it’s a bayer sensor. The bayer array is a 4 pixel pattern, so it moves one pixel to the right then one down and then one back to capture all 3 channels for each individual pixel. For things like film scanning it works flawlessly, I use it all the time.

Then it’ll do a 16 or 32 shot stack in order to do the same thing but with more resolution.

I would have gone the other way. He’s still 50 Cent today, but he’s less than a quarter 20 years ago.

I still like Svelte, but to me SvelteKit has taken up too much of its mind/devshare. Svelte itself is fantastic, especially as a Vue guy I love the "new" reactivity system/runes, but SvelteKit for me is horrible. It's just a hodgepodge of over engineered crap to cater to React/Next devs, and the Svelte team has also been hell bent on horrible decisions like the abomination that is routing[1] in SvelteKit.

To me Kit is the antithesis of what made Svelte so attractive to me originally. Svelte was dead simple and intuitive to use, Kit is anything but.

The router is really baffling, agreed. Magic file names make me so frustrated, and even more so when they all start with the same prefix so all my editor tabs look the same. I wish they’d just make a simple single file router that works the same as every other one. There are a lot of things that aren’t perfect in Vue, which I primarily work on, but the router isn’t one of the things that bothers me. It mostly just works.

Cash money

I’ve seen this one a few times and something about it doesn’t agree with my eye. It’s somehow in the weird awkward zone of not old enough to truly feel simple and functional, but not new enough to look modern minimal/clean. Might just be the font also, but I don’t find it very easy to read. Could just be me though.

Couldn't you use something like GitLens for that? I haven't used it in a bit but IIRC it lets you see your changes versus any branch pretty easily. Personally if I do feel the need for a view of what I've touched, I just open up a draft PR.

roblh · 3 months ago

You certainly can, I specifically like being able to see it in real time though. It’s less useful if it isn’t constantly present without having to bring it up with a click/command.

Maybe I'm just a scrub, but something that I find makes it harder to do smaller commits is that I frequently rely on being able to see which lines I've changed directly inline in my editor. When you commit, vscode now stops highlighting all of those lines, and that makes it much more difficult for me to orient myself relative to what I've already done. The individual lines, and the git pane that shows which files have been changed, act as waypoints for me while I'm working on stuff. It's particularly important on more complicated features that span more files, and I'll often intentionally commit stuff I feel like I'm not likely to touch again to reduce some visual noise.
