The Future Of Software Is Small — aparker.io August 3, 2025 · 6 min read

been having a think about software and platforms again, wrote it down.

Console output for a load test run with the command: ab -n 10000 -c 50 http://localhost:8000/ A few noteworthy stats are seen on the screen, including: Concurrency Level: 50 Time taken for tests: 0.602 seconds Complete requests: 10000 Failed requests: 0 Requests per second: 16615.33 [#/sec] (mean) Time per request: 3.009 [ms] (mean) Time per request: 0.060 [ms] (mean, across all concurrent requests) Transfer rate: 3602.15 [Kbytes/sec] received

That's as fast as it gets for a basic "Hello world" Wasm component that acts as a HTTP server.

Now onto adding actual functionality to see how it impacts performance.

I keep telling myself that I'll use Bluesky more, but I can't seem to bring myself to do so.

Gotta start doing so.

Us developers have learned the hard way that:

1. Prototyping is more like 10% of the actual work - even though the business folks thinks we're 90% done

2. Shipping prototypes to production is possible but generally a bad idea

Vibe coding is prototyping. Others will learn - soon

Please, someone show @mark-carney.bsky.social's team why and how to use markcarney.ca as a handle. (Assuming that this is the actual official account, of course)

Byzantine Eventual Consistency and Local-first Access Control Slides from a talk given at the 12th Workshop on Principles and Practice of Consistency for Distributed Data (PaPoC), Rotterdam, Netherlands, 31 March 2…

A few days ago I gave a keynote at the PaPoC workshop on Byzantine Eventual Consistency and Local-first Access Control. It wasn't recorded, but slides are here

Slide from https://kyleormsby.github.io/files/pB_matches.pdf TRANSFER MATRIX METHOD Building games(P x [n]) one layer at a time If G is a weighted graph with adjacency matrix A(G), then the entries of A(G)^n count the weight of length n walks between vertices. Define G(P) to have vertex set games(P) and a directed edge QQ' with weight the number of matchstick games on P x [1] with Q on 'bottom' and Q' on 'top'. For A(P) := A(G(P)), we have games(P x [n]) = sum_{Q,Q' in games(P)} (A(P)^n)_{Q,Q'}.

Still thinking about the time Don Knuth complimented my font choice for my slides. (That was before he knew I made the slides in Keynote. He hasn't spoken with me since.) 🧮

Dressing up the most boring coefficient possible, 1, as two Greek letters is pretty incredible

The Wikimedia Foundation, which owns Wikipedia, says its bandwidth costs have gone up 50% since Jan 2024 — a rise they attribute to AI crawlers.

AI companies are killing the open web by stealing visitors from the sources of information and making them pay for the privilege

i tried nix for the first time 2 years ago and I've given up on using it as a package manager locally (I just went back to homebrew), but I'm still using NixOS. Even though it's very confusing it still feels like the easiest way for me to manage a server

Nice short read this morning. I wasn’t super familiar with CBOR before getting into AT Protocol stuff.

"this website uses cookies" yeah and i'm fasting what do you want me to do

A Super VanJS sounds dope!

Curious: does CascadiaJS collaborate with Seattle.js folks when they host Seattle.js Conf?

If so, could there be something like that for VanJS? I'd be sure to get in touch with the current organizer of VanJS, and see if we can get something going.

Bluesky, Pixelfed, Mastodon, Signal

being older than someone doesn’t magically make you correct. 🙃

Tonight, on John Oliver's Last Week Tonight, #Mastodon and #PixelFed got a call out for not falling in line with Trump and as an alternative to Meta products.

I had to throttle my CPU down to 550MHz to make ext4 as slow as Apple's APFS

this is an ~10x (x 12 cores) speed *reduction* to match APFS "performance".

Tech leaders have a plan to protect Bluesky from Elon Musk - The Logic Free our Feeds, a collective of tech leaders including Wikipedia founder Jimmy Wales and Mozilla Foundation president Mark Surman, wants to raise US$30M to protect Bluesky.

You might be wondering why tech leaders are trying to save Bluesky, and not Mastodon.

Put simply, unlike Mastodon, Bluesky is not a mature de-centralized service. Almost everyone who uses Bluesky only uses the server run by Bluesky themselves.

This graph of Pixelfed instances is most worrying to Meta.

A measure of a decentralized social network’s sucess isn’t new users, or MAUs, or even engagement. It’s the active amount of servers.

In Pixelfed’s case servers have more than doubled within a month.
