I figured out the udev rule needed to flash a Pro Micro.

# /etc/udev/rules.d/81-promicro.rules
SUBSYSTEM=="usb|tty", ATTRS{idVendor}=="1b4f", ATTRS{idProduct}=="9205", ENV{ID_MM_DEVICE_IGNORE}="1", ENV{ID_MM_CANDIDATE}="0"

Setting ID_MM_DEVICE_IGNORE like the whole internet tells you to was not good enough!

Critically, ID_MM_CANDIDATE has to be set to 0 on the tty device in a rules file named 81-something.rules, to undo it being set to 1 in /lib/udev/rules.d/80-mm-candidate.rules (whyyy)

If your Sparkfun Pro Micro or other USB-connected AVR microcontroller seems to flake out partially through an avrdude firmware upload almost every damn time, but it has no trouble when you use an ISP programmer to write the firmware:

Try uninstalling "modemmanager"

If that works, there's some udev rules that will make modemmanager ignore the device so you can safely reinstall it, but I haven't quite figured them out yet.

Every time I make an S3 bucket my brain insists on trying to save money by enabling reduced redundancy storage.

So I priced it out and... wait why the heck is it _more_ expensive than standard storage!?

TIL: they're getting rid of it

I just discovered a box of fancy chocolate-dipped cookies that I had intentionally hidden in my kitchen a few days ago and forgotten about until now

What is wrong with me, I usually have a full mental inventory of all nearby snacks

This feels like a cutting indictment of my situational awareness

(They're actually my wife's and I'm not allowed to eat them. I had better hurry up and forget they exist again)

To be clear, this is real: samsung.com/se/unspoilme/eng/

Samsung of Sweden made a hypnotherapy recording to make people forget their favorite TV shows so that they can rewatch them "fresh."

You shouldn't need to know my credentials to trust me when I say it's a bad idea for you to actually listen to a hypnosis recording created by an international corporation seeking to profit off of you and play with your memories.

Honestly, pushover licenses are terrible

Note to my future self: the "Brother HL-2140 Foomatic/hpijs-pcl5e" printer driver works way better than the proprietary drivers from Brother's website.

Confirmed: if you portray yourself as a "git expert" in your interview, then in your first week on the job you will ham-handedly obliterate a coworker's branch with your own commits like a starry-eyed noob

and by you i mean me

@xrevan86 that's an estimate, and from a hobby project where one person writes all the power maintenance code themselves, not a giant watch company with a team of engineers. i think that's pretty good!

if it's possible to make it last longer, the project is open source, so anybody can contribute that improvement.

i've got a wireless mechanical keyboard that burns through two coin cells in 4-6 months 🤷 and modern phones and smart-watches don't even compare

@datagrok It's a very cool hack.
However one of the coolest features of the original f-91w is its little known resistance to magnets up to at least 3T. Even where the gradient is steepest, you can't affect the watch much, even waving your arm around just fades the display, and that's some *serious* flux.
Most digital watches reset at that point. Analogue break.

@a_breakin_glass you can buy them new on amazon for like $11 or cheaper used, and i see off-brand clones for $3

but part of my excitement about this project is that the author has done most of the hard reverse engineering work already, so a non-expert like me with a little bit of electronics knowledge and time could probably fork the project to do the same to other models of watch

@datagrok
That's super cool! Btw for people who do have a Pebble watch, there's an open source firmware and software project in the works called Rebble! rebble.io

@io you know what, for only $14, if we can get enough people interested I'd throw in for a kit too just to help it happen

i don't have time to do any organization around this though for at least another two weeks or so

@catdad @hisham_hm ugh idk what to say about security theater. I imagine that even if you're careful not to wear the wrong watch they'll make up some other excuse to harass people 😩

Have you heard of Star Simpson? MIT student who went to an airport with some blinky leds in her jacket, security lost their minds, and the school basically threw her under the bus youtube.com/watch?v=cQdl_JdTar

It's absolutely disgusting

@datagrok have you seen goodwatch.org/ ? features include:

- hex editor
- disassembler for the watch's own firmware
- amateur radio tx/rx for cw and several other digital modes

components are about $14 ea. for 10x

I really want to build one; hmu if you want to go in together for parts
