#mastodon #fediverse implementation question: would it be possible to use the protocol for carrying issue tracking & discussion, e.g. to make #distributed version of #github or #gitlab issue trackers?

I thought that technically these aren't that different from the usual discussion threads here, except maybe for some governance steps like deciding if the issue is closed etc... Perhaps someone already investigated?

Exactly what affine transformation is the raw function

(x,y) = (x+y, x-y)

Equivalent to? Like if I wanted to express that transformation in terms of translations and rotations.

AFAIK, there's not an easy way in Haskell to inspect at the type level what type a field has in a record.

What I mean is that that there doesn't seem to be a type family like

type FieldType :: Type -> Symbol -> Type

that we could invoke in ghci like

:kind! FieldType Person "age"

Why would I want this? For libraries like servant and rel8 that use parameterized records where the types of the fields vary heavily with the type parameter.

I guess I could hack it using generics. 🤔

I know that Megaparsec doesn't backtrack automatically and that you have to use "try" for that, but this behavior of "many" was unexpected. Why oh why doesn't it parse the final space?

Maybe I didn't read the documentation thoroughly, but I don't think it's actually spelled out in the Haddocks?

If I forget to switch a #mastodon post to "quiet public" before posting (I fail at that with replies all the time) is there any way to switch it to quiet without deleting and redrafting? It doesn't seem to work for me. Or am I doing something wrong?

Seeing the schedule in #julialang conference and the last survey, looks like the community is embracing more the idea of using Rust as a support language.

So my holiday reading was the (neo)Vim user manual. It’s very impressive to me how once you get a sense of the model - the concepts and how they relate… this vast surface area of functionality that seemed hard to remember before just becomes a thing you can derive commands in using logic and a handful of higher level principles.

There are wrinkles for sure, but overall I think it’s an impressive feat of design. 👏👏👏

I already made myself a minimal #rstats IDE in 5 lines of config. 🤣

is stack allocation (including call frames & locals) just a game of russian roulette ... ?

i can't be the only one who thinks this is weird.

Is there a blessed way to create a RAWSXP from an existing chunk of memory within C?

Specifics:

• The memory is already allocated elsewhere
• I don't want to use memcpy, just wrap the memory where it is such that the RAWSXP points to it.
• I don't want the garbage collector to know about it - I will free the memory myself later.
• It still has to be valid RAWSXP that I can use in R

This is a bit of a callback to this post: https://fosstodon.org/@coolbutuseless/111956983679205597

Sometimes I feel like, in an effort for everybody to try to present themselves as hugely empathetic, society has become a hell of a lot less empathetic in reality.

Hey fediverses, is there any good online shell scripting primer for non-programmers? Something like "automate your stuff with unix" or so, ideally focused on the methodology rather than gory details of shell scripting.

#dns #internet history question: is there any technical reason why the usual domain names are written backwards?

(as in, not this way: https://en.m.wikipedia.org/wiki/Reverse_domain_name_notation )

Or was that inherited from somewhere? (Where?)

#haskell q: are there any small and living haskell implementations with power at least partially close to ghc? (e.g., vectors, concurrent IO and TyFams)

The new @dfg_public funding programme "Research Software Infrastructures" will have regular calls twice a year.

Fantastic news for those of us who try to enable #BetterSoftwareBetterResearch in DE by creating methods and tools for the community!

Crashing a user's R session due to license validation errors is not an acceptable function. A license check should never terminate a whole session, even if the package thinks the license is already in use. #rstats
