Making Code Faster
I’ve enjoyed writing software for 40+ years now. Lots of activities fall into that “writing software” basket, and here’s my favorite: When you have a body of code with a decent unit-test suite and you need to make it go faster. This part of the Quamina diary is a case study of making a piece of the library faster.

Compile time evaluation in Nim, Zig, Rust and C++
Evaluating code at compile time is a capability that most, if not all, compiled programming languages possess, even if it can't be directly used by the programmer, but rather applied as an optimization. In this post, we'll explore a bit how to execute code at compile time in Nim, Zig, Rust and C++.

ZFS on a single core RISC-V hardware with 512MB
Is this feasible? Yes it is! OpenZFS on Linux compiled from sources for RISC-V, it will work with less than 250MB of RAM for a nearly fully filled 2TB zfs volume with 225.000 files! Even stressing the system and run in parallel (via Wifi): a…

Why does zsh start so slowly?
I’m serious about shell startup speed. I use tmux to open and close tmux splits all day every day, so I need zsh to start quickly. I used to use frameworks like oh-my-zsh or prezto and while I was happy with the functionality they provided I wasn’t happy with their impact on my shell’s startup speed. So, what do we do…

One-on-ones with executives
Often when an organization is going through some turmoil, executives think to themselves, “Ah, I should have some one-on-ones with the team so they can hear how we’re handling this.” On the other side, I frequently hear from folks who get nervous when they get these meeting invites, “The CEO/CTO/CPO/etc just scheduled…

Washed Up
Even if every technology jockeying for a spot under the 'web3' banner evolves beyond proof-of-work blockchains, these systems will still not be part of the web because they designed not to be. 'web3' ain't the web, and VCs talking their own book don't get the last word, no matter how much dirty money they throw at it.

We upgraded an old, 3PB large, Elasticsearch cluster without downtime
Back in 2018, now five years ago, we published a blog post describing our 400+ node Elasticsearch cluster. In that post we brought up an important topic: So far, we have elected to not upgrade the cluster. We would like to, but so far there have been more urgent tasks. How we actually perform the upgrade is undecided…

Holier Than Thou: Precision Holes by Drilling, Boring, and Reaming (2021)
It’s imperative that design engineers understand the full journey of the parts they design, from the drawing definition, through manufacturing, and inspection. One of the most common features in machine design is a hole. Whether it accepts a bolt or holds a precision bearing, it has to be the right size and in the…

Wrapping Up 2021. Leaving C++
2021 was not too kind to me. I discovered that I not only have OCD but OCPD, a personality disorder. If you’ve ever had a conversation with me where I just couldn’t let something go because it was wrong or incorrect and it bothered me, now you know why. I have, for better or worse, extremely high standards for…

Gemini is Solutionism
While I don’t care too much about ideas and projects that I believe to be dead ends or maybe even doomed to fail eventually, a recent interaction on Superhighway84 got me to write down a few thoughts on why I believe Project Gemini is a really bad idea.
