Modern Law of Leaky Abstractions Back in 2002, Joel Spolsky wrote The Law of Leaky Abstractions, and it's one of those pieces that's stuck with me ever since I first read it. 23+ years later πŸ’€ and I'm still bringing it up in conv...

Monte Carlo Simulation for Projections and Estimates I first read The Flaw of Averages by Sam Savage about 15 years ago, back when I worked in the finance industry. I don’t remember every chapter, but I do remember the central ideaβ€”and it has shaped ...

What if I told you there was a better way? In this post I talk about using monte carlo simulation and histogram charts to help not only in modeling the projections themselves, but to also help communicate the uncertainty in the model.

Raise your hand if you've ever been asked by leadership or stakeholders for an estimate (a project completion date, a cost projection, etc) ... and despite all attempts to communicate the inherent uncertainty, the number or date is now cast in concrete as what everyone assumes _will_ happen 🫠

Working on a fun new project ... anyone out there doing parametric #CAD with #JSCAD?

I'm writing a vscode plugin that lets you stay right in editor to visualize/export your work. I've got some ideas for some cool features, but I'd love to get some feedback from real folks working in this space :)

1/2) I've seen several posts dunking on data centres in space proposals, often by citing things like the cooling issue, radiation, power, etc.

Those are all valid concerns. But, Bluesky folks, the people making these proposals are not as dumb as you are assuming.

Can our billionaires in America develop a sudden interest in architecture and start building some grand things in our cities? We may as well get cool buildings and environments in exchange for our dystopia

My perhaps controversial assessment is that when you share the propaganda of your enemies to call it out or to mock it… you’re still spreading their propaganda and maybe doing exactly what they hope you’ll do.

Ever worked with a "Cowboy Coder"? Or perhaps, you yourself are that gun-slingin' cowpoke! What works in a smaller team or startup, can eventually become a liability as a team grows if not managed correctly.

Yep. Almost all of history from global warming, mass migration, 9/11 and the rise of Russia is downstream of not aggressively pursuing nuclear power. When you look at the body count of misinformation, misinformation about nuclear power ranks near the top.

As someone who watched the clone wars cartoons with my kids, I’m admittedly amused to see the term clanker re-enter the pop culture lexicon (from an etymological perspective)… but some folks are a little too excited at being able to use β€œClanker with a hard R”

Does your team "move fast and break things"? Or do you slow down and find/fix the root cause every time? As always, the right answer is the classic "it depends", and each approach comes with its own pros and cons.

Tiered Thinking in the Age of AI Not too long ago, everyone was wondering whether $20 a month for an AI coding tool was worth it. Today, devs are easily blowing past $200 worth of capacity in a single billing cycle, and it’s easy ...

As coding agents get more capable, it seems like they’re using more and more compute to handle longer and more complex tasks. Devs will increasingly have to start rationing where they do their AI thinking to avoid burning through their credits.
