shawwn / M1 Air Pink Screen Of Death.txt
Created August 6, 2021 14:34
My M1 Air periodically reboots itself every week or so. It's like the old Windows BSOD, except it has a pink stripe on the screen. This is the "Problem Report for macOS" that was generated after my reboot today.
panic(cpu 0 caller 0xfffffe001f495798): "dart-disp0 (0xfffffe2332f08000): SMMU(SMMU) error: SID 0 PTE invalid exception on read with DVA 0x32dc000 (TTBR 0 SEG 0x1 PTE 0x4b7) ERROR_STATUS 0x80000004 TIME 0x6e4d29833f5d5 TTE 0 AXI_ID 0)"

shawwn / why optimizing ML is harder than it seems.md
Last active August 6, 2021 07:36

a conversation about the einops lib and why it's hard to optimize ML:

<PapuaHardyNet> the solution is obviously jax acc to shawn

which is why i'm thinking to also build a jax equivalent and compare all three: pytorch, pytorch + einops, jax. Let's see if I have the bandwidth to do so

<nshepperd2> einops is really cool imo

shawwn / sorted_braille.txt
Last active May 18, 2021 15:40
Braille unicode characters, sorted spatially (by hand).
A white line (——————) indicates something similar to reflection: the
characters on both sides of the lines are the same, but every other
char was swapped. E.g. 0A 1B 2C 3D becomes A0 B1 C2 D3 on the other
side of the line.
Almost all braile characters seem to come in "pairs", which I find
quite interesting.

shawwn / On Louis CK and guilt.md
Created May 17, 2021 10:31
A comment I posted to HN about why people don't admit their guilt, which I later deleted.

This was a comment I posted to HN in response to "I hate that it's so effective to pretend like you're not guilty after you've been caught cheating." That got me thinking about why, so I wrote this. But shortly after I posted it, I felt disappointed that I wrote these words. So I'm posting it here as a memory and a reminder.

I hate, immensely, how effective "double down and never admit guilt" is, but I don't think there's anything we can do about it as a society.

Thank goodness most people don't have the guts to hold firm long enough to get away with it...
