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 🫠

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

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

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.

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 😅
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.

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.

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.

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.

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 ...
