Also, Lenses are really cool when dealing with nested data structures
  const committerLoginLens = R.lensPath([1, 'committer', 'login'])
  const isServiceAccount = R.test(/^svc.*/)
  const repositoriesSansServiceAccounts = R.reject(
    R.compose(isServiceAccount, committerLoginLens),
null-safe, deeply nested property accessors :D
10:43 AM
The R.compose is like (.) in Haskell in this case?
I wonder how that would look like in TS.
Not syntactically, but type-wise.
@Zeta yes, and it looks like a mess in TS.
And this is using TS.
TS just isn't 'smart' enough to infer any of these types, so you generally have to specify a lot of them. And there's no syntax as far as I am aware that would make it possible to type R.lensPath properly. You'd have to explicitly specify those types
If I were to type this I would generally put it in it's own function and explicitly type the function instead of trying to use the generic type signatures that ramda comes with
const rejectServiceAccounts: (RepositoryPair[]) => RepositoryPair[] = R.reject(R.compose(isServiceaccount, committerLoginLens))
Does TS even allow a type like type Lens s t a b = forall f. Functor f => (a -> f b) -> s -> f b?
I guess you can use some generics, but the f on the right-hand-side?
Yeah unfortunately you can't do that
I am not sure what the term is but there is no way to do <T, K>(whatever) => T<K>
Higher-kinded types, I think?

11:00 AM
@DanPantry Rank-2-types in this case.
I've seen you use this forall syntax a lot
I've never seen it used in Haskell
Is it optional?
Or does it have a different effect to just declaring f?
i.e, is a -> b -> a the same as forall a, b. a -> b -> a?

@202_accepted Well, I tried implementing the naive way, and when the query timed out after more than ten minutes, I knew that I had a problem. There's no way in heck the users would put up with a refresh rate of more than a minute. As it is, they're going to be complaining it's too slow, but unfortunately there isn't anything more I can do.

Unfortunately, no. It's all very simple stuff.
Huh, must be ultra big data then.
No, I've worked with bigger. The telemetry data warehouse was bigger. Still not that big by modern standards of big data, but big enough to be an interesting challenge.
How much data are you returning to the user?
One page.
How many elements from the query is that?

What makes it tricky is that the users need filtering and sorting on as many columns as possible, and the page size can be set in a range from 10 to 100 records.

It sounds like what you really want is a code review, so I suggest you to go ask your question at codereview.stackexchange.com . Bear in mind that people there will be able to help with python optimization and code inefficiencies, but the tuning of parameters such as number of epochs, bias vectors, and above all learning rate, will take someone with experience in the training of word embeddings (/ machine learning in general). For the latter, you should explain what your implementation does at a higher level. For instance, I'm not sure whether you use or reimplemented glove. — Nikana Reklawyks 33 secs ago

Dan GrownerThis is a fixed up version (following RAII principles) of my previous reviewal. I have moved the construction of the object entirely to the constructor to prevent any bad object states.

Q: Player tracking system in my roguelike game

Mark RobuckI have been trying to make a roguelike for years. Ever since I was a kid I messed around with it. I have a working prototype now, but it takes forever to write the code for each and every place that you can walk in the game. Is there some way to make it easier? Like a variable inside a variable? ...

Q: efficient ways to store input data in text files for ease of reading by a simulation code

user_1_1_1Simulation take as input many parameters. Assume simulation is in scripting languages like python or Matlab. Example of such inputs is a mixture of double arrays/matrices and Boolean values like below:- alpha =-3 beta = true gamma = 1 cost1=ones(2,3) cost2=zeros(4,2) One simple way is just li...
