going to bed now, good night

(this is still later than I would have liked but better than yesterday, and hopefully I will sleep for more than 5 hours)

I completely forgot to eat anything today since breakfast (except for an ice cream)

LB: this is *fucking nuts*.

on certain AMD CPUs you can just poke a random MMIO address from ring 0 and change the memory controller's scrambling pattern, on a live system, which completely jumbles the mapping between physical addresses and DRAM IC coordinates. since all memory protection features (IOMMU, SMM boundaries, etc.) are based on physical addresses, it bypasses *all of them*. you can read AND WRITE the SMM, fTPM, and even the C6 microcode save regions. wild.

going to bed at 5:40am, good night

(this is too late. I'll probably wake up in 3-4h because of the heat)

I wish all USB cables were labeled like this!!!

(Elecom brand, if anyone's wondering)

reminder: all those 'homemade hacks' for looking at an eclipse (looking through CDs, sunglasses, etc.) are going to damage your eyes permanently, and you won't notice until much later. they do not work.

you have exactly three valid options:
- look through certified eclipse glasses from a known-good manufacturer for <30s at a time at most
- go to your local observatory, they probably have equipment set up to do this safely
- project the eclipse on the ground using small holes but DO NOT look at the eclipse directly, also not through small holes

anything else will leave you with eye damage for the rest of your life. you do not want eye damage.

You'd expect that they skip certain numbers when numbering their vehicles, but apparently they don't…?

I forgot about the eclipse until today and now I need to make a pinhole camera

how come hashtags in posts from sharkey link to that hashtag on my instance, but hashtags in posts from mastodon link to that hashtag on the original post's instance?

good morning/afternoon. I'm still very tired

it's almost 5am, I should really go to bed now (but I still haven't done anything today)

every time I see a post with a cw of "aipol" I'm disappointed that it's not about the politics of Anguilla

good morning/afternoon
