When running my own startup, we used to have a saying: A deal is only a deal when the money is in the bank. Handshake, contract or commitment mean nothing.

This could have been Australia, but thanks to John Howard, Tony Abbott, Scott Morrison, the Minerals Council and the BCA, we wasted nearly 20 years subsidising gas and coal instead. What a waste.

Certificate from Just JavaScript

Certificate from Just JavaScript

Someone sent me the "Just JavaScript" course by @danabra.mov. It was a joy revisiting the basics with a well-thought-out mental model that made the learning journey fun. I would recommend this course for anyone picking up JavaScript.

Certificate of Completion for query.gg Alexander Karan has successfully completed the query.gg

I have been using TanStack for years, but I got some amazing lightbulb moments during this course. Highly recommend. TanStack has helped me build lightning-fast tooling for FinOps at work, and I love using their libraries.

Atlassian is still fully remote; their commitment to it is pretty strong. Our internal set-up makes working across time zones pretty smooth, to be honest. Of course, though, Atlassian is not as big as Microsoft and others.

About Slack's new rate limits... As APIs become the sneaky backbone of LLM-driven workflows, Slack's update to their API rate limits may be an interesting sign of changing tides.

Slack changes its API rate limits, another sign that the web is becoming more closed off due to LLMs. Ktor is giving you even more reasons to use it, all that and more in this issue of the @apisyouwonthate.com newsletter.

Got a heat pump before I got solar and I was paying next to nothing for hot water. Now with solar nothing.

Honestly donโ€™t know why they are not more popular. No one should be installing gas boilers anymore.
