"The land before modern APIs" by Darius Kazemi
(@darius)

Nice history of HTTP status codes.

"""
The numeric codes are assigned by groups [to] hopefully cover other protocols besides RJE (like FTP).
"""

This is from RFC 360, about a Remote Job Entry protocol (RJE), submitted in 1972. You know you're in deep, when reading a three-digit IETF RFC!

"Why we are not adding AVIF support (yet)" by Dejan Pelzel.

The founder of BunnyCDN shares their technical analysis and what needs improving first.

Nutshell:
- Terrible server encoding perf, unsuitable for on-demand, even with disproportionate resources. (Better algos?)
- Slow to decode/render. (Better algo, hardware support?)
- No progressive render, not even basic linear. (All or nothing.)

Bandwidth isn't everything :)

"Profiling live Wikipedia traffic with near-zero overhead"

Why does the substring() method in JavaScript do magic “argument swapping”?

It's existed since the original JavaScript 1.0 from Netscape (as rev-engineered by Microsoft). Netscape 4 briefly removed the behaviour with JavaScript 1.2 in June 1997.

But... that same month the misfeature completed standardisation as part of ECMAScript 1.

Thus, it returned with the release of Netscape 4.5 in 1998, and been with us ever since!

📣 New year, new blog post: I fell into the rabbit hole that is monochrome image dithering. I wrote down everything I learned! 👨‍🎓

(… and wrote a small demo that dithers an image with all these different dithering algorithms.)

An Exploration of JSON Interoperability Vulnerabilities 

https://labs.bishopfox.com/tech-blog/an-exploration-of-json-interoperability-vulnerabilities

The same JSON document can be parsed with different values across microservices, leading to a variety of potential security risks. If you prefer a hands-on approach, try the labs and when they scare you, come back and read on.

Classic splash screens from Adobe Illustrator and Mac OS.

Which version was your first love (or hate) with?

For me, it's Adobe 5.5, on System 7.5, using my dad's Macintosh Performa. Brings back memories!

Citibank is, in fact, not entitled to getting back the $500 million it accidentally paid back too early to creditors. The transaction was carried out by subcontractors and signed off by three layers of approvals, none of which understood what they were looking at.

Great reminder that tech debt, diffusion of responsibility. and outsourcing work... oft only appear cheaper because the real cost gets externalised. Think it won't happen again?

New blog post: "JavaScript performance beyond bundle size" nolanlawson.com/2021/02/23/jav

This is kind of a grab-bag post about all the different performance metrics I think about when writing or using JavaScript modules. I hope folks find it interesting!

We're all one of today's lucky "Ten Thousand" at some point, and likely will be many more times in the future.

Each of us take turns filling up on things that "most" people seem to know, for I have yet to meet one who knows all those "most people" things! (non-overlapping subsets etc etc).

Be kind to today's lucky Ten Thousand! ♥️

"Why Generation X will save the web" by Heather Burns webdevlaw.uk/2021/01/30/why-ge

This is something that gnaws away at me. Gen Xers and older Millennials (like myself) are nostalgic for the old, untamed, pre-centralized internet. The younger generation has no memory of this. What are *they* fighting for? (Hint: it's not necessarily the same thing. Gen Z probably doesn't care much about the hazy memories of us "boomers," and by "boomers" I mean anyone over 30.)

The unreasonable effectiveness of simple HTML

I've told this story at conferences - but due to the general situation I thought I'd retell it here.

A few years ago I was doing policy research in a housing benefits office in London. They are singularly unlovely places. The walls are brightened up with posters offering helpful services for people fleeing domestic violen

I came across a rather peculiar implementation of a string repeat function for JavaScript.

There's a built-in for this since ES2015, and prior to that, the following was a common idom:

> str = "x"
> count = 3
> out = (new Array(count + 1).join(str)

But, an MDN contributor thought - we can optimize this! Can you figure out how and why it works?

"Wikipedia is twenty, it’s time to start covering it better"
from CJR.

In a nut shell: We need good solid journalism, a lot of it!

Journalists and Wikipedia editors can and do strengthen each other. But, for day-to-day topics and news, I feel we're nowdays seeing too much journalism rely solely on Wikipedia and other tertiary sources, and too little little paid journalism to then serve as sources for Wikipedia itself.
