This is flawed. Turquoise is not blue or green. Also different displays will show different colors. And a lot of displays aren’t great at producing the hues in the green color space. Idk the test seems arbitrary, but I’m not color expert

New comment by cranx in "Replacing Protobuf with Rust"

cranx — Fri, 23 Jan 2026 12:04:58 +0000

I find the title a bit misleading. I think it should be titled It’s Faster to Copy Memory Directly than Send a Protobuf. Which then seems rather obvious that removing a serialization and deserialization step reduces runtime.

So this still uses the JNI for the ui? Unfortunate that is

I find it strange that number 1 is not about political capital and how you it got it or maintain it.

This is cool, but the UX of the arrows should follow the scroll mode of the device. You drag down on an iPhone to scroll up. Following the arrow and dragging up causes nothing to happen

This is cool, but do you throw away stuff when done with it or do you keep things at another permanent location? Like the tent that isn’t brought on every trip?

But we do. A series of mathematical functions are applied to predict the next tokens. It’s not magic although it seems like it is. People are acting like it’s the dark ages and Merlin made a rabbit disappear in a hat.

I think a lot of engineers think, “I thought of a complicated set of abstract ideas that mean nothing to anyone else but will demonstrate my superior intellect” and then make that. It took a lot of self control to not curse.

Why write this in rust to execute shell commands?

New comment by cranx in "My favourite animation trick: exponential smoothing (2023)"

cranx — Fri, 08 Mar 2024 11:56:34 +0000

Nice job, but it’s math, not some magic trick. I would like to see the animation functions graphed to describe how the numbers change relative to time.

New comment by cranx in "Bringing garbage collected programming languages efficiently to WebAssembly"

cranx — Fri, 03 Nov 2023 12:23:24 +0000

I can see value in running code on multiple browsers on multiple OSes via web pages. I’d hate to npm install 2k+ JS libraries I don’t know or understand to be able to compile a simple Hello World Kotlin program that runs on a webpage. There does seem to be some notion in the industry that everything should be in a browser/JS, sigh.

New comment by cranx in "I got robbed of my first kernel contribution"

cranx — Wed, 27 Sep 2023 15:51:04 +0000

I think this is a common issue that happens in software development. Some people just like to make thousands of changes that don’t impact logic, but let them own the blame for that line of code. I guess it gives some a sense of power, control, and ownership.

I think journalists would beg to differ. I believe that journalism is a good thing. Humans aren’t equipped to process all of Twitter effectively. Use Twitter for getting a signal of what’s happening or what interests you. To gain better information that’s been processed, digested, and summarized for you then I think journalism is great.

An alternative solution might be to leave Twitter. Talk to ppl irl. Read the news paper and I mean the paper (digital edition is acceptable too) not the website/app.

New comment by cranx in "Android in Docker without QEMU/emulator"

cranx — Tue, 04 Jan 2022 14:53:48 +0000

This is interesting, but I don’t see this as something for use in development of Android apps. Given all Android’s quarks and fragmentation the use of real devices and Google’s emulators will provide a better surface to catch bugs during dev. What’s the primary use case for these containerized versions of Android?

New comment by cranx in "Web3 is centralized"

cranx — Sun, 02 Jan 2022 13:57:48 +0000

The problem is that everyone assumes crypto is some type of panacea. People keep saying transparency and distributed as keys words to engender an idea. People are believing the idea, but I’m skeptical the idea can “walk the walk.”

Could you show my grandmother how to see the transactions on the block chain easily for any crypto?

IMHO Web3 is more of an idea people are using to profit than a real thing to create equality.

We’d also die of mesothelioma. But hey, the co2 was captured.

Do we need more fissile plutonium? More bomb plants sounds less desirable for the human race than transitioning to renewables.
