If you're into Rust, you'll know about the difference between Eq and PartialEq. Did you know that there's a secret third thing?

It's super fun to give talks!
Sadly, this time I have no idea what to submit...
Haven't really started any cool new projects since the last conference.
So is there anything you guys want to hear me talk about?

If I had 3 wishes from a genie, the first one would be:
Make every hardware designer stop using 2.54 mm pin headers for debug ports.
Give me a Tag-Connect, 10-pin FTSH-105 or anything civilized!

Nice big refactor done on device-driver.
The 'device' is no longer the only thing the compiler knows about. It's deeper integrated, which unlocks the ability to have multiple devices in one manifest.
On its own not too exciting, but the plan is to add templates so device families can be supported.

Embedded development is great because you'll have a datasheet that has multiple diagrams and sections about the wonderful PLLs, and how you can use them to flexibly divide your clock sources, wow, they are so great, here's how to use them, and then have one little "Note" that says "don't use this".

So I was able to get my hands on 8kWh of batteries for free :D
Just ordered a transformer. This is gonna be a really cheap home battery. And because it's a custom build, it's also easy to upgrade later or change the batteries if these ones deteriorate fast.
