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 🫠

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. codecube.net/2026/1/monte...

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. 🧪 #MLSky

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

“You can’t defend capital and people at the same time” … helluva quote

Dennis Detwiller@drgonzo123.bsky.social

The Dem leadership — as demonstrated by their utter failure to defend democracy — only exists for the protection of the capital-owning class. It's impossible for them to be relevant even in the face of this unfolding disaster, because you can't defend capital and the people at the same time.

I think something democracy has never faced before is a populace with years and years of algorithmically supercharged perceptions of “the other side”

To be honest though ... ChatGPT's sycophancy is helping democratize access to that multi-layered-bubble of agreeable yes-men 😅

Dennis Detwiller@drgonzo123.bsky.social

People really don't understand how warped the truly rich are. They exist in a multi-layered-bubble of sycophants, each paid half a million dollars a year to keep the consequences of that super-rich person's failures and the word "no" from their ears. They are flying blind with no real feedback.

Figured it out ... _turns out_, a .NET executable will have very different semantics around the current working directory in different contexts: - running from dotnet run on the project - running dotnet run on the .dll - when installed as a dotnet tool

I got into tech because it’s fun to take things apart, see how they work, and put them back together — or rearrange the parts into something brand new. it definitely feels like the new ethos is “bro why bother to learn? caring about that stuff is cringe, just go FAST bro” and that bums me out

dan@danabra.mov

the main thing that makes me uneasy about llms is the cultural backdrop of global war on knowledge. the war on knowledge isn’t new but now it’s cheered on from tech too. tools for thought pivoted to slot machines because that’s what people want. “how things work” is buried under opaque indirections

Before I get banned or blocked for going about this the wrong way… Does anyone know the best way to pull things out of the Internet way back machine? I’d like to go in and extract some of my very early blog posts from the early 2000s that I don’t have.

I think a lot about the “harmless” part of “helpful, honest, harmless” which has been the (vague) rallying cry of AI Alignment. I consider AI doing student homework to be harmful at the individual and societal levels. Very much in conflict with “helpful”.
