ST Just Killed CubeMX (They Split It Again)

ST just split STM32CubeMX into two versions: Legacy CubeMX and the new CubeMX2. In this video I show what changed, test CubeMX2 on the STM32C5, and explain what this means for all STM32 developers going forward.

The method, encapsulated in a single screenshot below.

Of course, there are implications for how you sensemake if you use this method.

For starters, you might want to build a sensemaking group in your org / friends group to just share field reports with each other.

Gero Takke created the Ottopot, a Teensy-powered MIDI controller with "nothing but 8 dials". But what dials they are! 14-bit MIDI CCs changes with a 1:1 mapping to physical movement provides an experience more akin to analog pots, but with continuous rotation

Do I have any followers familiar with Embassy + smoltcp + STM32, and interested in a paid consulting gig? I've got a company seeing dropped / missing packets, and it could be an interesting project + fun investigative writeup.

Dabao Evaluation Board for Baochip-1x A powerful new RISC-V microcontroller with mostly open RTL

@bcantrill.bsky.social Have you seen this “truly” open source silicon efforts from Andrew “bunnie” Huang? I think they’d be fantastic for the Root of Trust use case in an @oxide.computer sled. A little early days but really promising start. www.crowdsupply.com/baochip/dabao

TIL: The "AVERAGE" function in google sheets (and probably excel) handles things correctly when some cells in the range are missing.

This means you can have (for example) a 7-day moving average, centered on the current data, that includes the next 3 days that don't exist, then update when they do!

GitHub - dani-garcia/vaultwarden: Unofficial Bitwarden compatible server written in Rust, formerly known as bitwarden_rs Unofficial Bitwarden compatible server written in Rust, formerly known as bitwarden_rs - dani-garcia/vaultwarden

Shout out to github.com/dani-garcia/..., which:

* Is a Rust compatible server for the Bitwarden password manager
* Is easy to self-host
* Still works with the official desktop/mobile/browser apps, which also work to store/sync TOTP

It means I now have password syncing, across devices, self hosted!

Overclocking Raspberry Pi Pico 2 Adventures with dry ice and RP2350 - how fast can it go? – Pimoroni Learning Portal

The madlads at @pimoroni.com overclocked an RP2350 microcontroller from the base clock of 150 Mhz to a whopping 861.6 MHz.

It looks like 400-500 MHz can be stable on most Pico 2s, which is still wild.

In case anyone else needs to know:

Using Apple Virtualization with UTM with a linux guest (and maybe only with bridged networking+VLANs?), TCP Segmentation Offload makes the interface crawl. Installing ethtool and running:

sudo ethtool -K YOUR_INTERFACE sg off tso off

makes everything fast again.

Token Anxiety

A friend left a party at 9:30 on a Saturday. Not tired. Not sick. He wanted to get back to his agents.
Nobody questions it anymore. Half the room is thinking the same thing. The other half are probably checking the progress of their agents. At a party.
All the parties are sober now. Young people don't drink because they're going back to work after. Not inspired by Bryan Johnson, although that's probably a factor. The buzz they want now runs on tokens per day.

I keep noticing it on walks through the Mission. Laptops glowing everywhere. Cafes, sidewalks, heck even park benches. People walking with screens open like a flashlight guiding them somewhere. Less drunk laughter on the streets these days. More keystrokes.
Dinner conversations used to start with "what are you building?" That's over. Now it's "how many agents do you have running?" People drop the number the way they used to drop their follower count. Quietly competitive. The flex isn't what you've accomplished anymore. It's what's working while you're sitting here not working.
The vocabulary is what really gets me though.
People describe models the way sommeliers describe wine. This one has better taste. That one hallucinates with more confidence. Opus is bold, Codex is smooth. They talk about harnesses and reins like they're controlling
horses. Invisible whips directing invisible labor. Someone at a dinner said they keep

"Claude on a tight leash for code review but give it more slack for creative work." We've started borrowing the language of how we treat animals for something none of us actually understand yet.
Waking up and checking what your agents produced overnight is the first thing now.
Before coffee. Before texts. You open your laptop and grade homework you assigned in your sleep. Some of it is good. Most needs rework. But you start shipping a plan before you sleep just so you can wake up to more code written overnight. Saturdays became uninterrupted build windows. No meetings, no Slack, twelve hours of you and your agents. Sunday morning X is all terminal screenshots and shipping receipts. "What'd you ship this weekend?" replaced "what'd you do this weekend?"

The anxiety is rational, which is why it sticks.
Every week some new benchmark drops that makes last month's workflow feel prehistoric.
Codex ships overnight processing. Opus gets faster. Context windows double. None of it reduces the pressure. It multiplies it. You can do more now. And someone already is. The window to be first at anything feels like it's shrinking by the day. Literally, by the day.
I replaced Netflix with Claude Code. I lie in bed thinking about what I can spin up before I fall asleep, what can run while I'm
unconscious. Reading a novel feels indulgent now. Watching a movie without a laptop open feels wasteful. This voice in my head that says
"something could be running right now" just doesn't shut off. I'm not even building a company. I'm just addicted to building my random ideas.
Everyone here knows they should step away more. That's not the problem. The problem is what your brain does when you try. I still take a x ss walks. The agents come with me now.

Obsidian uses local files, so all your standard terminal commands work for editing/moving/searching/etc

Obsidian CLI adds everything else:

- interacting with the UI
- internal functions e.g. base queries, orphans, etc
- devtools, console, screenshots, eval, etc

See the CLI docs!

i think a core beef that i have with a lot of this "automation is bad" sentiment lately is that there is no inherent moral good in laboring

the story of humanity is one of invention, where we improve our conditions by building things that help us do more things more easily
