Since Bluesky doesn’t have polls yet, I’d like to try the following format as a workaround:

I will ask the question and then add one comment per poll option. To select an option, simply like the comment.

Okay, let’s try:

Who’s the best girl in the whole world?

No, I wanna sit in a classroom all day with free food and no obligations other than to listen and to ask questions :D

My school was in the posh area of town, so I had the privilege to be educated by incredibly talented teachers. Didn't appreciate it back then but now, I know what I had.

School is wasted on kids. I hated physics back then, but would love nothing more than to sit in class and listen to a great teacher explain electricity to me now.

If a company explains a layoff with “we don’t need these people anymore because of AI” this should be almost always translated to “we over-hired massively and now use AI as a convenient excuse to rectify our mistake without looking bad“

Great examples! I actually looked at the BMP280 specs and the pattern matches in the BMP280 library when I “designed” this table 😄

Great catch, thank you! I renamed it simply to `sign` since it's the sign of the float.

Ash lover, if you have time and you are a user of AshJson, there is a Feature-requested issue, which needs to be implemented 🤭

I always remembered it by thinking of a tiny manta ray which I'd call "mantissa"

Hey folks! We have a CVE up for #AshFramework bypass policies. It's a *highly unlikely edge case*. But, as always, we take security extremely seriously and will always follow proper procedure here. Props to @maennchen.dev for reporting and resolving 🙇

TIL or rather Today I Remembered how floats are encoded into bits!

This is the value "12.5" encoded into a Float64 (default size in #ElixirLang)

It's also a little teaser for my next blog post about binary pattern matching in Elixir ;)

A screenshot of how the value 12.5 is encoded into bits which is 1 bit for the exponent sign (0 for positive, 1 for negative), 11 bits for the exponent, and then 52 bits for the significand/mantissa/coefficient.

When I said that I prefer Bluesky web over the app because it’s so broken that I doesn’t get me hooked, I meant stuff like this 😄

Which is wise because you know them well enough to never trust them :P
