McKinsey and Providence colluded to force poor patients into destitution
Providence is a health giant whose anchor is a network of Catholic hospitals. They colluded with McKinsey to steal from their poorest patients, by deceiving them about their eligibility for free care, saddling poor, sick people with crushing debts:

I Built a Ruby Parser
Sorry, this post will read like a “dear diary” entry rather than some life-changing HN-worthy guidance. Back in November 2020, almost on a whim I started work on a new parser for the Ruby programming language. It was almost exactly a year after I had started working on my compiler project (I hope to write a longer…

The tech interview prep industry
Before I got into tech, I worked at a tutoring company in the Northern Virginia suburbs of Washington, D.C., doing a mix of schoolwork-related tutoring and standardized test prep. From a business perspective, it made so much sense - you have kids taking standardized tests and parents who wanted their kids to do well…

High-intensity exercise, some new news
Several months I noticed something interesting (to me!) about my heart rate, and I thought about blogging about it…but I didn’t feel like it would be interesting (to you!) so I’ve been hesitant. But then the NYT published something that is kinda related and I thought OK, what the hell, maybe it’s time for an update…

Regrets of the Dying (2010)
For many years I worked in palliative care. My patients were those who had gone home to die. Some incredibly special times were shared. I was with them for the last three to twelve weeks of their lives.

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.
