It is a testament to how much launch activity there is that the FAA has to restrict commercial launch to night to avoid impacting ATC during the shutdown.

We are knee-deep in studying the developer experience around containers, because if agents are going to be maximally useful, they need to be in a box. What we have discovered so far: sketch.dev/blog/in-prai...

If you want to try out the full-sized Qwen 3 Coder, we just added it to the latest version of sketch. Run with:
brew install boldsoftware/tap/sketch
sketch -model=qwen
(We handle running the model for you.) It is amazing how close this open model is to the frontier models. And notably faster.

The insidious way things get worse is deliberate, rewarded optimization. These steps made Hotweels measurably cheaper (or improved margins), with no measurable loss of quality. Because the quality was hard to quantify, or noisy, or deemed low value by a secondary metric (no sales impact).

Here is a writeup on using an agent to help me find the source of a bug when my own grepping had failed. It is a cronicle of barely 30 minutes of work yesteday, but serves as an example of how I get value out of these tools. sketch.dev/blog/fightin...

One of the features in Sketch I love is that it has a browser to take screenshots as it is working, and feeds those screenshots back into the model. This makes it much better at CSS-style work.

It is harder than it looks to kill PID 1 from inside a container. Got there eventually with a SIGTERM!

Before you write "Hello World" please:
1. type the website of a competitor's product
2. type our name (in CamelCase!)
3. choose a weird spelling of our programming language (in snake-case)
It is ok, we added dark mode.

This, from the iOS gMail app, is the most impressive UI dark pattern I have ever encountered. I fell for it for at least a year.
If you do not pick "Chrome" (which is not on my phone), it comes back every few months. You might think the correct choice is "Safari" but it's not!
