Q: Execute asynchronous read in parallel

Dmitry NoginI found it useful to execute multiple reads in parallel using a set of my extension methods for TaskFactory, which could be used as: static async Task Main(string[] args) { var (r1, r2, r3, r4) = await Task.Factory.StartNew( Read1Async, Read2Async, Read3Async, Read4Async); async...

Q: Python3 Simple Xor Pipe/CLI Program

Chev_603I wrote a simple python3 program that takes data from either a file or standard input and xor encrypts or decrypts the data. By default, the output is encoded in base64, however there is a flag for disabling that --raw. It works as intended except when I am using the raw mode, in which case an ex...

Q: Intersection of sorted lists

kyrillI don't like this function. Looks too imperative. It takes two sorted lists and returns a sorted intersection of the two lists. There is an implicit assumption that there are no duplicate elements in either list. Please don't suggest converting (even one of) the arguments to set, or using some ...

Q: Simplify & Reduce steps in the IsDistinct function

thisBecause I often have to deal with two Variants that may or may not be Null, we need a null-safe equality test, so I came up with IsDistinct which works but I have some issues with the code: When I tried to keep it terse, the readability was harmed. When I tried to expand the logic for readabili...

I seriously doubt that where you place import math will have any real impact on execution time. I agree with @Selcuk that `Code Review seems like a better fit for this question. — John Coleman 28 secs ago

Unrelated to your question: code review: Windows x64 guarantees 16 byte stack alignment before a call. If start is called in an ABI-compliant way, you don't need and rsp, -16, just sub rsp, 8 + 16*n (including any pushes). If you did want to over-align the stack, e.g. by 32, you can use RBP to hold the old RSP, again like compilers do if you use an alignas(32) volatile int x = 1; or something. So push rbp; mov rbp, rsp ; and rsp, -32; sub rsp, 32*n. Then of course you can return with leave ; ret. — Peter Cordes 13 secs ago

@Mast NGL, it doesn't make much sense to me either way.
 
@EthanBierlein I would guess that it's because they've posted 3 questions all starting with "Advent of Code 2019: " in the space of what like 10 minutes. Every time I've seen questions posted in quick succession I've always seen some downvotes.
@JAD Yes, I know what the word means.

@Peilonrayz I'm not a native speaker, may have to improve the wording later today.
The idea was removing parts of the title. I thought scrapping parts was appropriate there.
 
Eh, you speak better English than many people I know. "Scrap" has other connotations to me, so maybe I'm the one who's wrong. ;P
 
Thank you.

@410_Gone Any good documents on how to use Action and Predicate in a command. My problem is how to define an action and a predicate and I could use some examples. Basically I'm trying to implement MVVM and RelayCommand as described in docs.microsoft.com/en-us/archive/msdn-magazine/2009/february/…
 
Yeah, it's opinionated for sure. Sounds to me like a management, and not a coding problem. What are the (new) business requirements you need to implement? Upgrading to Wildfly cannot be a requirement. Which way you are implementing the requirement is (foremost) dependent on the team that needs to implement it and their skills. Also, I would advise to put that code on the codereview site. — Martijn Burger 35 secs ago
 
@pacmaninbw @MathieuGuindon Knows better than I.
 
    public class DelegateCommand : ICommand
    {
        private readonly Predicate<object> _canExecute;
        private readonly Action<object> _execute;

        public DelegateCommand(Action<object> execute, Predicate<object> canExecute = null)
        {
            _canExecute = canExecute;
            _execute = execute;
