check out this new primitive I'm working on for #GlasgowInterfaceExplorer! see alt text for an explanation
waveform diagram for a FIFO displaying the following test case:
1. writes start without any reads. for a while, writes are buffered in FPGA block RAM, but this buffer ends after 0x60 writes
2. writes spill over into external DRAM
3. reads start and clear out the data from FPGA block RAM after a while
4. reads un-spill data from external DRAM

Doctors say that cyclospora can cause explosive diarrhea. A guy who snorts cocaine off toilet seats and brings raccoon penises home for "further study" says that cyclospora cures autism. For busy parents, it can be hard to know who to trust.

I fact-check even when claims are convenient, because we can’t oppose misinformation while spreading it. Waymo does collect sensor data and can provide footage via legal requests, but there’s no evidence it shares data with ICE or tracks people for them.

For months I've heard crazy stories about SF's reorganized street medicine teams, which are now forced to focus on "the list" — a small number of homeless folks who've annoyed politicians or angry neighbors. This means every day they have to drive past people in urgent need of medical care. 1/3

Former Apple engineer here that has visited the Foxconn factories in China multiple times around the 2010-2015 time frame. None of the tools used in assembly of an iPhone require “small hands”. Designing fixtures to require a certain stature is an idiotic thing to do.

Do people read the terms and conditions before clicking accept? I assume most don't, and even when we do, those are digest. TOSAbout is a list of company terms and conditioned, explained in simple language, to understand how shady those are, before you click “accept” www.tosabout.com/
A screenshot of TOS About website, showing a list of companies in a left sidebar, and a human friendly summary of their terms and conditions on the right, highlighting the good, the bad and the ugly, with a grade. In this example, Adobe has a 1/7. Companies are rated using emojis, from poo emoji to puking, and being sick emoji.

That should work. There are no mitigations and I believe DPA attacks have worked against slightly newer silicon than that. Might need a lot of traces though.

My pill organiser I designed to hold the immunosuppressants for @photographotter.bsky.social's kidney :) Printed plastic & CNC milled aluminium, with Photter's picture engraved into it.
A half-open pill organiser with deep places for pills, two for each day. It consists of a bright aluminium pill tray (with a handle that has an image of Photographotter's sona engraved onto it), which slides out of a matte black plastic housing. Inside each pill pocket is an orange plastic liner, perfectly sized for the many pills contained in them.A more head-on photo of the organiser, showing the engraving on a slidely-slid-out pill tray.

You’ve been given an address that points into a binary, but it’s had a random value added to it. Subtract the unslid address from the random value et voila, you have the slide and can now create any address* by simply adding that slide to it. *some libraries might be slid independently.

MISO MOSI the right way around? If that’s all correct it does sound like ringing on the lines. Probably can’t change the drive strength but some resistors in series (100 ohm or so) could help. Lowering the frequency down to the sub-MHz range as well.
