"The hard part about software development isn’t figuring out the problem, or coming up with the solution, or writing the code. The organizational coordination, and making sure that everyone feels empowered and motivated and has ownership, is the really hard part”

Applies to some tools, but this is where fine design makes a difference.
Code is cheap to prompt, but the real bottleneck to good products is thinking through 99,999 design decisions and considering every edge case.
DIY-ing your own tools will teach you how hard beautiful, thoughtful design is

I think this is exactly the math that is going to drastically change the small SaaS landscape
why would I pay monthly for <tool> when the same cost (maybe less!) can make that and also anything else I need

I pay $100 a month for Xero (accounting software), and I do wonder if upgrading to Claude Code Max for a month or two would pay for itself to write a robust replacement.
It probably won’t get bank feed imports right, but that’s broken in Xero for some accounts anyway.

After reading this I gave exe.dev a shot and the combination of cheap VMs, the HTTPS proxy with passkey auth and link sharing, and the built-in LLM agent is... incredible.
Like, I know how to use each of these things individually, but combining them feels like when I first learned to script things.

Just in time software
I didn’t plan to write software in the grocery store last night. I was tired and hungry, kids in tow. My long shopping list sat in a text message. I wished I could check items off as I found them.…

It's just such a shame that we have to live in such a world
The domain is active again, but with a new registrar.
And they're asking me for $2,000 to get it back.
I don't have that kind of money; I don't even have enough money to live on.
It's shameful to extort money from open-source projects that have minimal resources.

There are things that empirically work and things that empirically don’t work. I’m often surprised at how much trouble people have in telling the difference.

Accepted! Go 1.26 will introduce per-state goroutine metrics: running, waiting, in syscalls, etc.
Developers can use them to catch problems early without needing full traces.

I love that sites like eBay basically stayed the same all these years. And I hope they never change. Some times a product/service is fine as it is; it doesn’t need a never ending stream of ‘improvements’.

For an introvert, the real gift is finding someone whose presence feels calming instead of draining. Some people make you feel light and safe, while others drain your energy within minutes. Time with the right person feels effortless, with the wrong person it feels like a marathon

LOL I can't resist retweeting this
So tempted to write a troll thread on how this incident shows Rust has bad error handling and wouldn’t have happened in Go, where we actually handle errors 🫣🫢😜
