  1. This one, obviously.

  2. Things I never thought would happen: my parents asking me to cast a YouTube video of an Archspire drum cover to their TV.

  5. Does a poppadom imply the existence of a poppasub?

  6. Turning 32 and I feel like Vincent Adultman. "Hello, other grownup!"

  7. I'm actually wondering whether I should put a few drops of hydrogen peroxide in the tank and run it through with clean fluid, just to flush the lines...

  8. What's funny is that the fluid *should* contain a significant percentage of ethylene glycol or propylene glycol, both of which are bacterial growth inhibitors, but my guess is he's been using stuff with only about 5-10% glycol in it and left it for a long time.

  9. I contacted the eBay seller I bought the 1500W smoke machine off and gave him a heads up to check his smoke fluid stock before he turns up at a gig and causes an evacuation due to stale fish smell. 🤮

    A lot of tweets about miss that 02 February 2020 is a palindrome in USA, UK and ISO formats; it is a palindrome day of the year (33) and there are a palindrome of days left in the year (333). This will never happen again. More details here:

  11. Are there any cryptosystems that rely on trapdoor functions where the hardness specifically and directly arises from the halting problem?

    Anytime a rich person donates money, this is how you should report it.

  13. With fresh fluid in it smells a hundred times better. Still not perfect so it might be a case of stripping it down for a proper clean out to get rid of any residue. Works a treat, though. Massive clouds of fog in a fraction of a second.

  14. Need to properly remove the tank at some point for a full clean, but it's got a fluid level sensor hard-wired in so for now I've just given it a couple of rinses it out with hot water and Star San. Next job is to refill with fresh fluid and fire it off outside for a while.

  15. SO HORRIBLY GRIM. I didn't realise that the fog fluid left in the tank must've been in there for years. House now smells like stale fish. Cleaned out the fog fluid tank and it had a bunch of floating white gunk in it. 🤮

  16. About to test my new 1500W smoke machine...

    “Oh gosh. You know, I'm not much on speeches, but it's so gratifying to leave you wallowing in the mess you've made. You're screwed, thank you, bye.”

  18. Hacking this implementation to process a rectangle of pixels within an image should be significantly faster. Likely sub-millisecond processing times on a single core. At 60fps that's under 6% of my CPU time budget!

  19. Even using it in the most naive way I could think of (one call per row in every block) it only takes ~3ms, which is about as fast as my implementation that cheats and only samples a small subset of pixels.

  20. While looking into something completely different I happened to stumble upon this project on GitHub. It's a C++ function that performs ultra-fast colour averaging over an image using SIMD. Benchmarks show a full 3840x2160 image can be averaged in <2ms.
