Fascinating deep dive on Twitch deliberately constructing a 10GiB array to reduce the number of GC cycles in Go: blog.twitch.tv/en/2019/04/10/g

(This trick is no longer necessary in the new Go 1.19 apparently, as it's added a GOMEMLIMIT environment variable.)

“I don’t care how you web dev; I just need more better web apps”

Published this yesterday. We keep talking about frameworks or web components but, personally, I’d just like to see better websites and web apps baldurbjarnason.com/2022/more-

Re-watched Rich Hickey's "Simple Made Easy" and now I can't help but see the "easy vs simple" distinction everywhere. Like marketing websites for frameworks that say "The easiest way to get started with…" Everybody wants easy, but maybe what they should really want is simple? youtube.com/watch?v=SxdOUGdseq

"Police Are Looking to Algorithms to Predict Domestic Violence"

"""

Deno Fresh reaches its first stable release.

The demo source is readable, revive logic easily found, and I could step through all fn call in minutes, and understand it. That's huge.

Fresh is a bit like Hotwire, Remix, and Svelte. Server-first, 0KB default JS. It doesn't invent a new component framework though, but recognises JSX-compatible islands, where you can e.g. use Preact, autoloaded/wired by Fresh.

I did a quick re-record of my talk "Why HyperCard was so f***ing great" from NSConference 2014 based on the original notes and slides. In case you always wanted to know what HyperCard was: youtube.com/watch?v=2K1C5BZKP3

How effective is paid advertising anyway?

Scott Cunningham, on the selection bias in paid clicks:

"""
[..] there was a nearly one-to-one increase in natural clicks [..] as though users were already going [..]

Reminds me of 2020, when in the Netherlands the NPO (national broadcasting service, akin to BBC), removed third-party tracking and actually increased their revenue in doing so: techcrunch.com/2020/07/24/data

"When You Should Prefer Map Over Object In JavaScript" by Zhenghao He zhenghao.io/posts/object-vs-ma

This sounds about right to me. I'd simplify the advice to "use Map for hashmap-like things." The fact that small integers are fast in Objects is probably just because it's a common pattern, so V8 optimized for it. V8 could decide tomorrow to optimize for the same thing in Maps. (And why not just use an Array in that case...?) Also none of this is likely to be a big bottleneck in a website.

Archive.org captures in real-time new posts from self-hosted WordPress blogs, plus anything they link to, and does something similar for new citations on Wikipedia articles.

I wrote down how this works, and how it all ties together.
(The rabbit hole got me on this one, I'll say! 😅)

"Data outlasts Code, yet Code keeps winning" by Shawn Wang swyx.io/data-outlasts-code-yet

This is an interesting way of framing the debate. There are a lot of good points in here.

"How an Obscure Far-Right Website With Three Employees Dominates FB", analysis by Judd Legum for popular.info (via Daring Fireball).

This stuff is basically as-expected with present day FB algo and incentives. This particular incident makes a good case study though. Solid !
