absolutely deranged ad on reddit, pay to have this website display your customised "frame"(?) for a minute of the day?? please politely fuck off lmao

it's basically modelled on the stock market, buy a minute now for $1 and maybe if you're lucky and the company pop off you can sell it later and make a profit

if you have never watched a Folding Ideas video, watch this short 4 minute one and then consider the fact that this man produces long form content with the same level of eloquence and skill

i've been craving Folding Ideas content since the silkposting talk he did, his eloquent dismantling of Mr Beast has barely satiated me

Why was I invited to Beast Studios?

Soooo... I spent a great deal of time yesterday trying to figure out why pmOS duranium images were breaking fastboot mode on the OnePlus 6 / 6T. This did not happen with mutable pmOS images. This wasn't caused by us using u-boot to EFI boot on this phone.

Wanna know the reason? Are you sure? Because here be dragons...

this version fixes small bugs that @cas and i found during bringup and integration over the last months, and works around some USB2 limitations on 8550 by adding another hub and muxes for EDL (usb bootloader) to optionally route around the hub. other little fixes are around SD card level shifting, PWM, choice of unreserved SPI pins on 8550, and a wrong displayport hotplug detect pin.
MNT Quasar Beta version fully routed, tomorrow i'll do some mechanical interference checks/changes and then it's done. this module will support 3 different Qualcomm Dragonwing processors:
- QCS6490 (integration mostly done, low idle power consumption, can do sleep/resume, can disable hypervisor)
- QCS8550 (works, very fast incl GPU, but need to fix some GPU issues)
- Q-8750 (up to 4.3GHz Oryon, will test end of May)
guess i gotta learn german just to watch anime, crazy how german netflix doesn't have english subs for a bunch of shows

I almost have stock Debian 13 booting on this DragonBoard 410c with U-Boot, firmware is the issue. I would like to revisit PostmarketOS on it too. It's a really interesting little board - the worst thing about it is the size of the RAM. I can work within that though. I need to figure out how to add more packages to Postmarket OS though.

like the overhead is tiny but it adds up substantially
Working on a lil pet project in rust rn and discovered that using Result in the hot path is significantly affecting performance, how do people deal with this?
