Agreed. Shovel Knight is one of the best platformers ever made, except for all of the other really good ones. Especially if Spectre Knight is as fun to play as Plague Knight.

It's a bit of a lazy way out, but the Occarina of Time "series" would fit nicely. The "sequels" are Majora's Mask, Windwaker, and Twilight Princess, which all exist independently for timey-wimey reasons. Majora's Mask and Windwaker in particular are the best examples of what they...

There's always positions that are "do this other thing, also it gets a lot easier if you spend an hour or two programming something". Pretty much any job with Excel is like this, as is system administration or client-side web development (I would wager most javascript programmers don't kno...

This is the exact tradeoff you get between rapid-release and LTS distros. In general, rapid-release distros have a habit of making it so if you neglect updates for too long, you no longer are able to update at all without breaking something ("losing your upgrade path" in enterprise-ese). L...

Speaking of how Java is terrible, Kotlin looks pretty promising if it lives up to the marketing hype. Judging by its comparison to Scala, it would've been better if the kotlin organization had invested their efforts in Scala. :?

It's sort of cheating to implement IO in a language that's already impure. ??? Why? What makes it "cheating" Because if you translate what you did to Haskell, what you really have there is Identity. Specifically, only in a language where side effects exist outside IO can you pass nonIdemp...

Notice that you weren't able to learn Reader properly until someone pointed out the definition to you. No, the *definition* I'd seen plenty of times. I'd read over the Haskell wiki definition of it several times, and saw several tutorials giving servicable definitions. It was the *implementation* o...

headprogrammingczar

Reader is completely different, because it actually has an approachable implementation. Maybe you're hung up on trying to make IO a good example to learn with, when in reality it's one of the worst and it can't really be fixed by calling IO a container. It's a lie (which isn't inherently bad, some l...

headprogrammingczar

You're still really hung up on this container idea, as if IO always has something inside it. For purposes of reasoning about it, it's abstract. It's a mystery cloud of who-knows. It may contain something, it may not. Maybe it all gets lifted out and at runtime there's no IO values anywhere! GHC's vo...

headprogrammingczar

IO *is* implemented as a container, though. IO and Reader are *literally the exact same thing*, and both of them are *literally the exact same thing* as Function. In functor form, they're all a container holding a function that you'll evaluate later when you want to extract the "value" fr...

headprogrammingczar

But the concept of "what a functor does" is much wider than that. I know there is an (evidently heated) discussion of the niceties of functors in full play here, much of it over my head at present. I was interjecting an actual "Fleeting Thought" into the flow of things. ;) My co...

Why: If X is a complete type, m is an instance of M<X>, f is an instance of a Callable type and std::result_of_t<F(X)> equals M<Y> for some type Y then m * f is an expression of type M<Y>. And not: If X is a complete type, m is an instance of M<X>, f is an instance of a Callable type and std::resul...

In math, "the functor" is the combination of the type and the definition of map, which you combine in a tuple. For instance the notation for defining a monad is (T, η, μ), with T being the type and η/μ being pure / join . Applicative theoretically would only requires ap , and then pure wou...

headprogrammingczar

It's really hard to read this with no types or laws, and with functions and methods being totally mixed up. A type `F` is a functor if there exists a function with the type `F<B> fmap(Function<A, B> f, F<A> a)`, obeying the following laws: For all a, fmap({x => x}, a) = a For all f and g and a, fmap...

headprogrammingczar

No, this is really not analogous. The point is that by allowing only "global" numbers you would forbid the natural "add" operation of the numbers data type. My reasoning is that partial application (which is what you're doing in your code snippet) is not a natural operation on f...

Eval isn't what was meant by creating new functions at runtime. You can't define this "appliers" in C without writing at least 10000 lines of code. (#) = \x -> \f -> f x appliers = map (#) [1..10000] An analogous situation would be: you can store numbers in variables, you can pass them to ...

To use the specific term, not being able to construct arbitrary function bodies in C makes it not possible to write closures. You can hack it with lambda lifting, but it's obviously not pretty.

Yeah, it was about due for an ending (especially after the last season finished up with a perfect series-finale episode.) But at least they pulled it off reasonably well (if a bit abruptly.) Definitely better get Fillion in something else ASAP, though. (Also: CBS, you're doing a new Star Trek . Pro...

There's a memoization technique you can use, which removes the lambda between xs and id. Much like functions in any other language, when you define something in a lambda, it's recomputed each time that lambda is applied. What you can do is the following: -- the same as what you have now let id = \i ...

The mushroom spores seem to be unobtainable by cross-breeding. I've tried in pure darkness, in daylight, and with the potatoes in daylight and the netherwart in darkness (on diagonals). I can't tell if I am doing it wrong or if there's a bug. Infina, can you confirm?

Why not just read 3 bytes for every random number? Then you have an even range to run the modulus on and all is right in the world again.

You're going to have to explain that first point, because State is perfectly expressible in H-M as far as I am aware. A good thing to mention that that Haskell does above and beyond H-M is type classes. Or you can even just run down the list of GHC extensions. Rank-N types are notable for being impo...

The combat aspects of this game might even beat out Freespace 2 for me.

Dealing with your shields being down and plotting a jump out, you have to stare at ...

I also just found that Freespace 2 can be played co-op as well, and I like how the story is tied into stuff objectives that are designed to be failed. Might try that with friends.

headprogrammingczar

Can anyone think of any other games with a good story that can be played multiplayer? Something like Borderlands or Synergy for HL2. Ideally not expensive, and it doesn't have to be an FPS.

By the way, when you want to do anything interesting, you aren't dealing with Reader, Writer, or State directly, but some other thing that implements their mtl class equivalent. Ironically, that ends up being easier to understand, because instead of "here's this simple concept, depicted here in...
