Q: BMG is slowly dying

Let me put it simply: BMG, which was a good idea at first, is dying, to the point that we're not scheduling new ones, we're not hearing about it, we forgot that there was meant to be one on Tuesday, we tried to schedule one same time today and forgot again. So, what should we do about this?

Dude coinheringaahing

Q: Simple cat program

One of the most common standard tasks (especially when showcasing esoteric programming languages) is to implement a "cat program": read all of STDIN and print it to STDOUT. While this is named after the Unix shell utility cat it is of course much less powerful than the real thing, which is normal...

Redwolf Programs

So learn-a-lang is going to be more of a "long term" event, right?

Dude coinheringaahing

The highest voted answer (mine) suggests something more like BMG - a scheduled event for an hour or so specifically dedicated to that lang

Although I'd imagine the length would last as long as people want it to - no need to forcibly kill a popualr thing

Redwolf Programs

Maybe there could be an event like BMG that starts it off, and people can continue to discuss and post CMCs on the language over the next week or so?

Unrelated String

hmm

Dude coinheringaahing

12:47 AM

That sounds like a good idea

rak1507

I imagine if people like the language, activity in actual solves and cmcs will go up naturally

Dude coinheringaahing

We could schedule a specific time for the "starter" event, then discussion would slowly decline after that, while still be slightly more in the zeitgesit

Redwolf Programs

)

What the frick, chat

I had a whole long message typed out and it reloaded right before I hit enter

Dude coinheringaahing

) indeed, can't disagree with that

Redwolf Programs

I was going to say, having a single event sounds like a bit of a bad idea to me, since if you miss it for a language you really wanted to learn (or teach) it'd be much worse than just missing a BMG

So emphasizing it being more of a longer-term (i.e. a few days to a week) thing could make missing the starting event a lot less of an issue

Dude coinheringaahing

12:50 AM

IIRC if a mod schedules an event here, it shows up on main. So long as we decide the language a few days in advance, that should'n't be a massive issue

Unrelated String

twice-daily cmcs over the span of a week?

Redwolf Programs

@Dudecoinheringaahing I'm not getting up at 3 AM to learn Jelly, no matter how far in advance I'm warned :p

@UnrelatedString I think more of an "unscripted" sort of thing would be better, idk

People could just ask questions or post CMCs whenever

I don't think the more rigid structure of BMG would be needed for this

Unrelated String

mmm

Dude coinheringaahing

@RedwolfPrograms No, but we can save the initial event as a conversation, include a link to it in a pinned message (something like "The current Learn-A-Lang is <blah>, check out [here]() for the starter event. Feel free to post CMCs and discussions about it") and keep it in the zeitgesit

Redwolf Programs

Yeah, that's along the lines of what I was suggesting

Dude coinheringaahing

12:53 AM

The problem with events is that someone will always want to be part of it who can't, for various reasons. I think a starter event specifically about the language, followed up by however long of "topic about X is especially on topic" should work best

Redwolf Programs

Maybe we should change the BMG schedule to always be on wednesdays to reduce the confusion with when it is

I don't think the tuesday vs. thursday thing actually matters for anyone anyway

Dude coinheringaahing

Cycling the time between 12am and 12pm UTC could work as well

Redwolf Programs

Maybe we should just do that honestly

Cycle between two times, always on the same day of the week

I think just knowing when BMG is, and having to remember to sign up for it (since it was too complex to be set up as a recurring event), is one of the major factors that's made it annoying to remember to attend

Dude coinheringaahing

I think that should work well. We could create two recurring events that run every 4 weeks?

Redwolf Programs

Yeah. That way, you can sign up for the time you're usually available (or both), and you don't have to remember to re-sign-up (or for us, create the event)

Unrelated String

@exedraj Which is a very good way to do it

Dude coinheringaahing

Dang type overloading :P

exedraj

@Dudecoinheringaahing So if you want a list of characters, you need to manually quote each one

But you don't need to quote a list of numbers

Redwolf Programs

Overloading > vectorization :p

You can always vectorize as part of overloading, but the reverse is not true

Dude coinheringaahing

Imagine not using both :P

Redwolf Programs

1:41 AM

That's what any sane golfing languages does :p

All-vectorization works but is inefficient, and all overloading with absolutely no vectorization is almost certainly bad design

emanresu A

When you have to multiply by 1 to take implicit input

Dude coinheringaahing

Tbch I do think that golfing languages should take the Jelly approach to types (where there are two "atomic" types, numbers and character), but overload commands for those two (which Jelly doesn't do)

Redwolf Programs

Vectorizing over arrays of strings is nice for some stuff, but I could see that approach being viable too

Although two atomic types isn't taking full advantage of overloading :p

exedraj

@Dudecoinheringaahing The only real problem with having a list of characters for a string is that you lose the ability to have nice string manipulation elements

Redwolf Programs

emanresu A

1:44 AM

Redwolf Programs

You have to have the same ones with arrays as strings, which is fine 90% of the time, but kinda dumb sometimes

Dude coinheringaahing

@exedraj Jelly has halfdecent string manipulation commands

emanresu A

Redwolf Programs

But those come at the cost of array manipulation commands

emanresu A

Ok, how did I end up with this?

Dude coinheringaahing

1:44 AM

@RedwolfPrograms Lists should always be collections of atomic types IMO, never an atomic type

exedraj

@Dudecoinheringaahing I know, and I'm not saying that it's a bad idea, I'm just saying that I've seen some people sometimes wish jelly could do string stuff better

Dude coinheringaahing

And I personally prefer strings = char lists

@exedraj I so wish Jelly could do string stuff better, but that's mainly the atom choices, not the typing choices

Redwolf Programs

@Dudecoinheringaahing I wasn't saying lists should be atomic types, I was saying there should be more atomic types added in :p

Dude coinheringaahing

@RedwolfPrograms What is there aside from number and character?

exedraj

@Dudecoinheringaahing so it's mostly a problem regarding lack of string features?

Redwolf Programs

1:47 AM

Having functions can be nice sometimes, but I'm saving all of my more uniue overloading related ideas for an upcoming language :p

So no spoilers

Dude coinheringaahing

If Jelly could overload some of the integer array atoms to work on strings (e.g. Ḍ) most of it's problems with strings would be alleviated

I'd even argue things like "Truthy indices" would work, because how often do you have an empty char in your string?

@emanresuA enamresu A is the most common cause of gram-negative sepsis in adults. They are found in the gastrointestinal tract, where they can live as commensals in a mutualistic relationship with their host. Sepsis is characterized by immune dysregulation that leads to the excessive production of inflammatory cytokines. Overproduction of tumor necrosis factor α (TNFα) is associated with the development of sepsis. TNFα production is regulated by TNF receptor-mediated NF-κB activation.
