I must investigate...

@durron597 There's no need to remove tags from questions that should be deleted.

@JimmyHoffa Maybe Eric Lippert knows?

@ThomasOwens There is when you don't have 10k rep, don't want to nag a moderator and want to nuke a tag

But you bumped a terrible question.

@ThomasOwens I support your decision to delete it.

@Telastyn Thanks.

@WorldEngineer I'm certain he does, but you are not helping me

Telastyn

@JimmyHoffa - the forearch doesn't count, the for(i=0; i < stuff.Count();++i) does

also Count the property doesn't recount, but Count() the method almost always does.

@Telastyn oh well yes; I know that...

@MichaelT I suppose copying and pasting someone else's non-close reason comment as a close reason doesn't simply upvote their comment

who the hell wouldn't know that? Ugh, probably that guy who's currently teaching people to program even though he's been doing it all of 3 weeks himself in Ruby

@durron597 trueless

@JimmyHoffa truth monad

7:44 PM

@durron597 ...there is a truth monoid.... monads require a parameterized type though

@durron597 given the closed set {True, False}, what binary operator is associative on this set such that x * (y * z) = (x * y) * z?

Telastyn

well, I assume that Robert Harvey knows that, but if people aren't using foreach subtle things like that are often the reason (or y'know... C++ programmers that don't know any better)

@Telastyn I don't believe I have the context for your comment... I should look up and see what bobby said

@RobertHarvey you should definitely change your SO name to RobertTables....

@JimmyHoffa OR and AND are both associative...

user20683

@JimmyHoffa his current name is effectively Strongly Molten Iron

@durron597 for either of these binary operators, can you come up with an element in the set that acts as an identity i such that i * x = x = x * i

ratchet freak

7:53 PM

@JimmyHoffa for AND true and for OR false

> Monoids are easy

Monoids most of us rely on frequently for their handy short-circuit ability:
Set of `boolean`s under `AND` with `True` as identity.
Set of `boolean`s under `OR` with `False` as identity.
Set of `object`s under `null coalesce` with `null` as identity.
Set of `List`s under `concatenate` with `[]` as identity.
Set of `String`s under `concatenate` with `""` as identity.

okay...

@durron597 you did that to yourself you know.

when I read about all this monoid/functor/monad stuff I found the only real obstacle was the unfamiliar terminology

once I map "monoid" to "IReducable" in my head it makes perfect sense (assuming you're already familiar with the map/filter/reduce operations from less pure languages)

@Ixrec if you're already familiar with those, you're a fair bit ahead of where a lot of people are to begin with

8:05 PM

but Javascript has them, and everyone knows Javascript.

LINQ is 8 years old, you still can't find .NET people who know reduce (Aggregate in LINQ) basically at all.

a lot of the LINQ syntax/behavior is easy to get mixed up

@whatsisname ...huh? how do you figure? You mean the comprehensions or even when written in fluent syntax?

I'm mildly surprised that the name matches the tag badges

8:09 PM

that is actually pretty awesome

though I'm certain there's countless others with the same name lacking the distinguished database expertise Little Bobby Tables should be known for...

I find it easy to mix up whether I want Take or Skip or While etc for example if I haven't done a bunch of LINQ recently

it's easy to mix up the name<->behavior mapping

100 linq samples in C#

@whatsisname I don't think I've ever used while... and how can you confuse take and skip? They're antonyms...

all words in computer science are overloaded, I wouldn't really blame anyone for getting anything mixed up unless it's among those few words used consistently everywhere

take/skip feels kinda like car/cdr, but with an integer argument

Yeah, in Scheme I believe they use first and rest.

8:15 PM

@Ixrec this is relatively true, and it gets harder with more general interfaces; I could see confusing take, at, or select

I think map/filter/reduce/fold are among the few super-short words that almost always mean exactly the same thing

select 3...I want the 3rd one, oh wait no that's wrong, take 3.... no damnit at 3 oh there we go

@Ixrec HAH! map absolutely does not mean map in C++

as functions, obviously =)

pshaw, in C++ it probably still means something weird, like launch maps.google.com or something

destroyBaghdad();

8:19 PM

checked, in C++ map is just the container, the map operation seems to be covered by std::transform

and in classic STL fashion, std::transform can do a bazillion things, so it's probably good they didn't call it map

perhaps I should have said almost always mean the same thing in dynamic languages

it feels like all the dynamic languages have at least basic bits of functional programming

There's a core collection of functional concepts.

for some definition of "core."

no doubt that core is some dialect of Lisp

come to think of it, I think I first learned map/filter/reduce from reading the SICP

@JimmyHoffa: I can't even remember what most of the methods are off the top of my head

without intellisense my productivity goes down to 5% of normal in C#

8:36 PM

@whatsisname well, you just don't practice a lot of C#, or practice other languages at the same time likely... that's to be expected. .NET is a stupidly large framework and the classes have an gonzo number of properties and methods.

someone forgot to escape strings...

> Description contains invalid character(s) <>"'&/\.

for a single " \ "

oh wait, that's a list of all the bad characters, someone forgot UX / HCI

@enderland forgot ? Who actually knows that stuff... UX folk are rare as hell unless you mean marketing people selling themselves as "UX"

Q: In Gary Bernhardt's talk about Ruby and JavaScript surprises, what does "wat" mean?

designing a UI from scratch is hard, but once you've been told what to make, doing all the little tweaks to make it usable is usually pretty easy tbh

There's a video of a conference presentation by Gary Bernhardt about surprising behavior in the Ruby and JavaScript computer programming languages. At the beginning of the video, Seth asks the audience: You guys know what 'wat' means?" [He makes a 'wat' sound. He also shows a silly photo ...

meaning slang

best commit message ever. lol

I've been serially upvoted in the [Intersystems-Cache] tag on SO. I could be as much as 2/3 of the way to first bronze badge in that tag.

If it's not reversed.

@Ixrec might want to link to the guide. I've got a bit about licensing in there.
