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),
    repositories
  )
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
ie
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?

@DanPantry Rank-2-types in this case.
 
I've seen you use this forall syntax a lot

Q: Delete node from singly linked list with tail pointer in C

SMCI'm trying to implement a single linked list based on Linus' comments about double pointers. In my case I'm also using a tail pointer and I'm wondering if there's a better way to update the tail pointer which does not require the conditional below? I'm still new to C so any other critique is 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.
 
Interesting, is there anything bizarre in the JOINs?
 
6:29 PM
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?
 
6:34 PM
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.
 
What RDBMS are you using? Being NASA-related I'm guessing Postgre?
 
SQL Server
 
Oh wow. Have you looked at the execution plan for the query yet, to see what's slow?
 
@202_accepted I asked the DBA, and she said the problem was the table size.
 
Ah, that's unfortunate.

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

thanks jon! can u provide an example of a template reference that would not be component relative? ie it work in jit but not aot? I'm not sure how someone would configure the template url in a different way then I did in the example I provided, but I'd like to know what to look for in case I'm doing a code review sometime — user8570495 36 secs ago

Q: Struct Array Data Member being default static

user148632I have a struct with a double array member. The problem is that instances of this struct all seem to use the same array. This leads to all the structs being identical to the most recent struct that was initialized. struct myStruct { private: double x[2]; //rx,ry,rz,vx,vy,vz publ...

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? ...

Complete the function sortSegments that will segment the string into substrings of consecutive letters or numbers and then sort the substrings. For example, the string "AZQF013452BAB" will result in "AFQZ012345ABB". The ...
