I'm expecting the Channel 4 ADHD "documentary" to be a complete and total insult to everyone with ADHD, given how they've billed it. disingenuous people without ADHD talking about us authoritatively, ignoring our experiences, giving "equal time" to reactionaries, attempting to stir up controversy for ad revenue. the way to combat this cynical bullshit is to just talk about our experiences twice as much. talk over these loudmouth fucks and give people a direct view of...

watching Bill Wurtz's "History of the entire world, I guess" for the hundredth time because it is easily the best video ever committed to the internet. if you are one of today's lucky few who haven't seen it yet and get to experience it for the first time, please set aside 20 minutes and enjoy the single most entertaining summary of human history ever made. I cannot recommend it highly enough. https://youtu.be/xuCn8ux2gbs

planning a project to replace the hexlight I take to EMF. each line (edge) is an LED bar, with its own PCB. each bar is a single dimmable unit. each point where lines meet (vertex) is a connector block. I want to plug in a single data input and transport it across the assembly. the challenge: no fixed positions, no configuring jumpers. any piece can go anywhere during assembly. I'll pixel map it after. the main challenge is doing that given the multiple paths. I wonder if RS485 would wor...

I just learned that the Nullius mod for Factorio requires sulphur hexafluoride to make power switches - now that's the kind of detail I love.

I'm looking for a new job. I've been in security for 13 years. I spent the last year at Trail of Bits doing code reviews and security assessments on desktop/web apps, kernelmode code, and firmware. I co-wrote the C/C++ testing handbook we published recently, contributing the Windows usermode and kernel sections. I've got strong hardware skills and industrial experience. UK based but flexible on operating hours. Looking for similar work, full-time remote. CV: https://poly.nomial.co...

predictably, just got my first email from a peertube instance who are moving to a paid operating model because storage is unsustainably expensive.

do I know anyone who has used RSSI from BTLE or WiFi APs as an ad-hoc positioning system? i.e. your device knows where N different beacons are in space, and figures out roughly where it is by extrapolating from their RSSIs. would love to chat about it and get some idea of how good the reliability and spatial resolution is, especially in crowds. (should go without saying, but I'm asking for the purposes of interactive art and not creepy surveillance)

does anyone have a spare #emfcamp spaceagon front panel I can buy? happy to pay the sale price plus postage. I don't tend to use the badge much so I didn't order one, but now I'm regretting it because I had a fantastic idea for next time.

at some point it would be cool to do a really chill liquid D&B comedown set late one night at EMF, maybe starting at 2.30am or something.

Since a few people asked, here's the setlist for my closing DJ set on Sunday at #EMFCamp #Nullsector. I had an absolute blast doing this one. In the months running up to EMF I put a shortlist of tunes I wanted to play together, but as soon as I got up there I was like "screw it, I'm just gonna run with whatever feels good" and didn't even look at the list. Thanks to everyone who came and listened - y'all had so much energy and I can't stop grinning when I think ba...

@whitequark@social.treehouse.systems not a clue, tbh. I'm not super familiar with the details of the memory model on these MPUs. I'm just following the wizard in CubeMX. within CubeMX it's just DRAM bringup, clock tree, and some peripheral config on the Boot side. then on the Application side I've got some more stuff like wolfSSL. my assumption, based on some examples and guides I looked through, was that the Boot part runs from SRAM, brings up DRAM, then the larger Application...

hmm. I'm confused. looking at an STM32MP1 series MPU in STM32CubeMX. it supports bare metal mode with FreeRTOS. I configured it to have 2Gbit (512MiB) of LPDDR2. export it to STM32CubeIDE. build it. failed. it says it can't fit the generate ELF's bss into the SRAM region (the actual issue is that the total of .text, .data, and .bss won't fit). the DRAM bringup code is already part of the boot context. what am I missing here?
