"Profiling live Wikipedia traffic with near-zero overhead"

I wrote all about it in this year's Performance Calendar:

"The land before modern APIs" by Darius Kazemi

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!

The solar flare just hit, all your digital lifetime's work is gone.

Yes, you _can_ have an interactive search feature on your static site! No need for servers or paid subscriptions here. Thanks to the open source Lunr and the power of Hugo static site generator, you can create a client-side search index with just a template and some JavaScript.

A number of my readers have been kind enough to tell me that you find my blog useful, but there’s something that you don’t know. Up until I recently implemented a search feature on…

"Re-Creating the Porky Pig Animation from Looney Tunes in CSS" by Kilian Valkhof

This is a fun one. Getting Porky's legs to appear behind the circle while his body is in front of it is surprisingly tricky.

Quick thoughts on why I set up a Gitea server of my own and if it’s time to look to more open/​stan­dards-based col­lab­o­ra­tion tools.:

One of my favorite things about compiling Chromium is that while the compiled files count goes up, the total file count also goes down.

Hi #mastodev folks: is there any effort in the works to make "remote follow" and "remote boost" etc, of posts something less than a 4 click experience? #Mastodon

rant on apple and planned obsolescence, repost from reddit 

@cadadr I'd sure like to be able to use Android, as productively as I use my iPhone. As a blind person, Apple can't be beat in mobile accessibility. Also, Lidar is *already* providing accessibility applications, like being able to tell how many feet in front of you a person is! So sure, for normal, able people you can sure use Android, or heck even Pine phone! But for blind people, Google doesn't give a *damn* about Android accessibility, and neither does Pine Phone.

I created this "Maslow's hierarchy of jobs" about 20 years go. Iv'e found to be good guide for when was time to move on (or stay). If you're failing at one or more of the lower 5 levels (pay not likely to continue, getting paid but nobody cares what you do) might be time to find a more productive gig.

You probably won't see this from HR in goals setting and performance management sessions.

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?


"Truly Doubling Down on Open Source" by Tomer Levy.

The saga continues... is partnering with numerous organizations (presumed not to include Amazon) to officially re-launch the open-source distribution of Elasticsearch and Kibana, with a separate entity overseeing the commitment to staying community-driven and under the Apache-2 license forever.

This could get interesting :-)

More on less curl memory - curl now uses a mere 30K of dynamic memory for downloading a large HTTP file,
plus the size of the download buffer.

"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.
