While parenthesizing this will technically work I'd reject it in a code review. This is confusing enough that you should rewrite it to avoid multiple ternaries. — Chris 53 secs ago

Q: Enables markup to instantiate objects, call methods, and generate HTML

mrherouxI'm looking for a code review for the package PXP. https://github.com/hxtree/PXP/ "PXP enables markup to instantiate objects, call methods, and generate HTML. It works similar to a server-side templating engine, but rather than enforcing braces it enables developers to use markup to build dynam...

User1973 I have polylines in a GIS database. The polylines are stored using a user-defined type called ST_GEOMETRY. ST_GEOMETRY has lots of spatial functions. However, it does not have a polyline midpoint function. Therefore, I have written a custom PL/SQL midpoint function. As a novice programmer, I...

Q: Project Euler 21: Sum of amicable under 10000

J. Cricks Let d(n) be defined as the sum of proper divisors of n (numbers less than n which divide evenly into n). If d(a) = b and d(b) = a, where a ≠ b, then a and b are an amicable pair and each of a and b are called amicable numbers. For example, the proper divisors of 220 are 1, 2, 4, 5, 10, ...

I see two things: One is the use of so-called "magic numbers", the other is the redundant stripping of spaces. BTW: There's codereview.stackexchange.com, which may be a better place for such a discussion. Anyhow, one more simplification: Use 97 <= ord(i) <= 122 as condition inside the loop. It does the right thing in Python. — Ulrich Eckhardt 10 secs ago

@Mast Hmm, do you think this will effect the LCC and UWYA dynamic? Such as as make it seem like UWYA is less or more correct to pick when it's not LCC.
 
11:16 AM
@Peilonrayz It will change the dynamic, although I'm not sure how.
 
If the code is working, then this might be better at codereview.stackexchange.comuser3121023 14 secs ago
 
Initially there will be more confusion, so probably more mistakes. Eventually, I'm guessing it's going to improve the situation.
 
Ok, that sounds like a good thing. Also what a time for the change, just when we want to change LCC too 😂
 
Yea, almost perfect timing.
@skiwi @Malachi Found the problem by the way, scope of the last formulae was wrong.

For me this code is perfectly fine. When you have to return a CompletableFuture but you only get one conditionally, your only option is to return an already completed future in the alternative case, but it is perfectly fine. Note that it might be a better fit for Code Review. — Didier L 23 secs ago

I'm specifically looking for feedbac...

 
I don't get what you're trying to achieve here. There's too little relevant info and too much distracting stuff. For example, remove all that shape stuff, it's not relevant what a vector stores when the question is whether an index is valid. Also, could you show working code that you want to improve? With that, it might even be better to take this to codereview.stackexchange.com. — Ulrich Eckhardt 47 secs ago
 
1:59 PM
while (input < 0 || input > menu.shapes_count()) I mean you have to get the value somehow. I don't really understand your confusion or the issue. This question has too much information for a minimal reproducible example and too little for a codereview, plus it's on the wrong site. — super 13 secs ago
