hey did you know that since 2017, the PNG format officially supports embedding EXIF metadata?

did you know that even prior to that, because PNG is an extensible format by design, tools like ImageMagick could preserve EXIF metadata when converting to PNG by embedding it in a nonstandard chunk?

in the context of some of my recent posts, can you see where I'm going with this?

if i had a nickel for every time i've seen someone's self-hosted blog with unredacted geolocation exif in the images, i'd have three nickels from today alone

here’s how Bernie can still win the papacy

❤️ reverse-engineering undocumented file formats
💔 reverse-engineering documented file formats because the docs are wrong

a lovely pair of honkers, if I do say so myself.

You know how spelling bees are largely an english-speaking thing, and that countries whose languages are phonetically consistent don't really have them?

I think about that a lot when I see people posting C++ brainteasers.

who called it Adobe’s Generative AI and not Photoslop?

finally clearing through the 400+ browser tabs I’ve accumulated on my phone, apparently some of them are old enough that they’ve link-rotted already

You know how people in tech often dream of pursuing farming?

C++ friends, is there a standard way to iterate over unicode code points (not code units) in a string (or i guess a u8string)?

edit: yes i know how to decode utf8 manually, my query is about the stl specifically

Consider this code. One thread repeatedly prints the number 100 in decimal to std::cout. Another thread repeatedly prints the number 0x100 in hex (which will output as '100') to std::cout.

You might reasonably expect that the output will simply be '100' over and over and over.

Unfortunately, the calls to operator<< can get interleaved so you end up with crosstalk of the format specifiers:

questions that can really derail a sunday evening:

is std::cout thread-safe?

(not in the way you'd want it to be, no)

it's always fun when you're trying to build software with a compiler that's old enough that its C preprocessor doesn't support such novel features as variadic macros
