Check out Kiro! Kiro moves the AI IDE from 'vibe coding' to development driven by specifications. Specs allow AI-powered development that's repeatable, scalable, and deals better with large and complex projects.
This is Kiro - the AI IDE that actually works on your messy, real-world projects. Other AI tools lose context when projects get complex. Kiro gives you spec-driven development that scales beyond prototypes. Free preview available now spr.ly/6016429H8 #KiroDotDev
I find that there are simple and self-contained coding tasks that can be completed with just a series of prompts. For those, the simplicity of Claude Code or Q CLI is actually an advantage over the feature richness of an IDE.
I don't really get Claude Code. Why do you guys want to sit in a terminal to look over changes vs the multi-tasking capability and UX of the whole IDE? I must be missing something!
The shortest path between two points on a curved surface is a geodesic. Except when a bunch of humans can’t find a way to coexist peacefully. Image is a flight path from Dubai to Baku shared by a family friend. Normally a 3 hour flight, now takes 7 hours.
In the last 10 years, teams from Florida have won NHL Stanley Cup more times (4) than teams from Canada (0). Go figure!
Recently, I've been discussing throttling with one of our teams. It's a super deep topic, probably deeper than it gets credit in modern systems, so I decided to write some thoughts on the matter: blog.joemag.dev/2025/06/the-nu…

There's the other extreme too! While reviewing the metrics for Amazon Bracket (AWS service that lets you run tasks on quantum computers) we joked that given their uniqueness and scarcity, they are neither pets nor cattle, but more like family!
There needs to be some philosophy that's in between pets and cattle. I nominate Furbys. There's still loveable and cute and you care about them, but there's a lot of them and they are pretty easily replaceable.

Is @TiVo having a massive outage? Neither my DVR nor my iPhone app have been able to connect for the past few days.
Are we approaching a point where choice of (at least written) language is becoming irrelevant? In a group chat today half the people spoke Chinese while the other spoke English. We all understood each other just fine because the app translated back and forth. And really well!
they don't want you to know this, but you can visualize arbitrarily hyper dimensional spaces in your head. just keep stacking!
Just think of it like a bunch of 3D spaces stacked on top of each other, like in all the multiverse fiction, and you have magic universe sliding powers. Now 5D that’s rough.
Yikes. Having a fire this big close to dense residential areas is terrifying. Wishing for the best, but looks like it may get worse before it gets better. Hopefully everybody makes good decisions and prioritizes safety. Stuff can be replaced, lives can't.
