Prikvačeni tweet
Is that an unsafe block? My pair programming buddy is always ready to fend off the nasal demons.

Only other options seem to be to jerry-rig an M.2 card, or to write HCI firmware for the Nordic USB dongle (I've heard that Zephyr might have this, but haven't been able to find it).

Hey
@NordicTweets -- Do you know if *anyone* makes a USB-stub style HCI dongle that supports BLE 5 or above? I've been looking for months and all of them seem to be BLE 4.0 - 4.2.Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
Then when it finally does die, and you want to charge it back above the threshold, the PMIC is all like "It's 120 degrees in here! This battery is WAAAAY deader than I thought! You're gonna have to charge it for like two hours to get back to the threshold!"

The worst part about debugging PMICs is that you have to sit there for hours because the battery won't fucking die.

Usually in a way that would have appeared to work (but been riddled with soundness bugs) if I had written it in C++.

All of my multi-day screaming matches with the borrow checker have ended with me realizing that there was something subtly wrong with the way I was trying to do something.

Programming in
@rustlang is just like programming in C++, except you're required to pair program with someone who is way, way better at C++ than you are.Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
Should I do anything else after writing to the spi flash? There was something about locking security pages that I didn't quite follow.

Tried bootloader.bin first and it *looked* like it was working, but I wasn't able to switch to a user image after flashing with tinyprog. tinyfpga_bx_fw.bin seems to do everything correctly as far as I can tell.

@TinyFPGA I think I managed to fix it, but just wanted to double check - Do I want bootloader.bin or tinyfpga_bx_fw.bin?https://github.com/tinyfpga/TinyFPGA-Bootloader/releases/tag/1.0.1 …Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
WTF does modemmanager even do, anyway? Tethering? I bet more people know it as the destroyer of serial ports.

While I'm waiting for my afternoon coffee to kick in, I've got a few thoughts about security audits mainly in the area of expectations and results.

Hey
@EbenUpton@JamesAdams314 - Congrats on the#RaspberryPi4 launch! Any chance you're considering breaking out some PCIe lanes on the Compute Module 4?Hvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
This could be compelling now that the
#RaspberryPi4 is claiming desktop-replacement-lite performance. 20 hour battery, anyone?Prikaži ovu nitHvala. Twitter će to iskoristiti za poboljšanje vaše vremenske crte. PoništiPoništi -
Has anyone tried gutting an old laptop (maybe a ThinkPad X220) and designing a drop-in motherboard that breaks out a

Honestly, after seeing the claims this morning, I was expecting to find some major cheating. I still think the initial claim is a bit of a stretch, but despite that, it still looks like Ambiq has a pretty clever design here. I'm looking forward to playing with it! 11/11

It's also slower than a normal digital design at the same node, because it takes longer for the tiny output currents of the not-switching transistors to charge up the gate capacitors of the next stage. 10/11

This lets you use dramatically lower voltages (and gives you power savings) if you're willing to accept certain trade-offs. Namely, the design process is harder (it's not just a process trick), and the circuit is more susceptible to noise, temperature, and process variation. 9/11
