hey hey hey
Wow have I had an adventure today. Two cancelled flights, two last minute bookings, one hour of sleep. It'S bEeN gReAt. It's all in the name of attending a once in a life time event though (about a 70% chance of that being true), so I think it's worth it.
Here's an interesting outline on how you can make money doing open source stuff.
Welp, it's the last issue before the weekend. Hope you have a good one.

The Middle of the Square

Published: 8 August 2022
Tags: algorithms

John von Neumann was a prodigy and a polymath who made notable contributions in pure mathematics, physics, game theory, economics, and the design of computers. In this article, Brian Hayes dives into one of his pseudo-random number generating methods called the middle of the square algorithm.
Some highlights:

  • Pseudo-random number generators aren't actually random (wOw!)
  • The simulation technique, in which random numbers determined the fates of thousands of individual neutrons, came to be known as the Monte Carlo method
  • The old random was worse than modern random (heh)

35 Million Hot Dogs: Benchmarking Caddy vs. Nginx

Published: 14 September 2022
Tags: benchmarking, networking, nginx

This blog post is about benchmarking Caddy against Nginx and their respective performance metrics as reverse proxies. Tyler Langlois providers a methodology and tons of stats and graphs.
Some highlights:

  • Nginx will fail by refusing or dropping connections, Caddy will fail by slowing everything down.
  • Nginx’s caching behaviors let it really shine with static asset files
  • Nginx uses an almost effortless amount of memory. Caddy peaked at almost 160MB real memory allocated for non-breaking tests, which may or may not be significant depending on what amount of total memory is available to the OS
  • Caddy’s default configuration is good

The state of Flow-based Programming

Published: 28 August 2022
Tags: flowbased programming

This is an introduction by Vladimir Sibirov to flow-based programming, combined with deeper analysis of where and how it can be applied today or in the future.
Some highlights:

  • FBP is easy to understand and keeps flow diagram based documentation up to date (because it's the code)
  • Doesn't make software easier to write/cleaner/or codeless
  • FBP is an interested and not fully mature paradigm that can be explored and built upon
