Q: Good practices for a class

OmarI was working in a class, but there are a lot of things that I'm not sure if they're a good practice or not. For example, the => instead of the { }. When should I use it? Also, I'm not pretty sure about the keywords const and readonly. For example, uriImage and key it's something that won't chang...

Q: C++20 Coroutine Generator

I'd consider posting this under CodeReview rather than StackOverflow... From a personal experience / opinion point, avoiding duplicating what amounts to a few lines of easy to read & understand Linq logic and trying to abstract out and then re-integrate a predicate builder isn't worth losing sleep over. ;) — Steve Py 5 secs ago

Q: Parallel word recognition in a Non-deterministic finite automaton in Rust

alexfertelI have implemented a simple NFA that recognizes words in parallel. All the code is on GitHub, here. A main recognizes method tells if a word (&str) is recognized by an NFA. Inside this method, I set up a thread pool and a channel and call a recognizes_in_parallel method. The recognizes_in_paral...

@Duga Rollback by Heslacher
@Duga Example i/o, not program code
 
Never heard about CodeReview, will check it out. I agree that over-abstraction just adds complexity but in this case I think it would make sense. In this trivial case with just two entities it's easy to maintain the query logic, for sure. But what happens when more properties are added to e.g. Brand and there are more relationships to each entity? The downside would be that as soon something changes in an entity I have to update this query logic on different places through out the codebase. Thanks for your opinion anyway! — Slamdunk 7 secs ago

@Peilonrayz Question seems borderline - works for some inputs, takes too long on others. I know that's not what we usually mean by "scales poorly", but it's about acceptable.
 
@TobySpeight Oh, I just totally misunderstood your message D:
 
@Peilonrayz Ah, I see I was too terse there. Yes, I meant that the edit didn't touch the code block, but only a code-quoted sample block. Sorry for confusion.
 
@TobySpeight I think my "example -> off-topic" radar may have been a too eager too :) No problem, sorry

tbh, if I was reviewing this code for one of my team members I would initially have an issue with the nested if/else statements but after working through it I would realize this is "sadly" probably the most elegant way of doing it. Part of code reviews is the ability to read and understand the code. In this case... its easy to read and understand. Because its basically "math", it might be good to comment the math calculations so that others will understand it. Otherwise seems fine. — Kenneth Garza 56 secs ago

@Vogel612 don't know if I believe you .... writing code that works the first time out of the box..... lol jk
@SᴀᴍOnᴇᴌᴀ shouldn't that be redacted? I hope that's not a Real IP
I mean it's easy enough to find those, but they gave an open port number too
 
@Malachi I believe 10.x.x.x are private
 
@Malachi FWIW because of the way some of the corner-cases I dealt with are very reliant on race-conditions, most of the code is basically untestable
 
@SᴀᴍOnᴇᴌᴀ pretty sure you are right, but semi private. aren't they on a LAN or something usually or an internal network

A: Is it better to use the 192.168.x.x or 10.x.x.x address range for a small business network?

Ben QuickRFC 1918 may offer you some guidance on this. At the end of it all though, you've got to design your network to suit, well, your network. If you've only got ~50 devices on the network, then any /24 (255.255.255.0 netmask) will more then suffice What do you estimate your growth to be? Will a /24 ...

3. Private Address Space

   The Internet Assigned Numbers Authority (IANA) has reserved the
   following three blocks of the IP address space for private internets:

     10.0.0.0        -   10.255.255.255  (10/8 prefix)
     172.16.0.0      -   172.31.255.255  (172.16/12 prefix)
     192.168.0.0     -   192.168.255.255 (192.168/16 prefix)
 
I didn't know about 172.16
 
While the specific 10.*.*.* address might be somewhat sensitive, it's not something anyone can use too easily
 
Heh before I realized that was a private IP address I did plug it in to geobytes IP locator which I have used before... and saw the map location was somewhere off the west coast of Africa (likely 0,0)

@Malachi For all intents and purposes, knowing someone's IP in the 10.0.0.0/8, 172.16.0.0/12, or 192.168.0.0/16 space is completely useless.

I’m voting to close this question because it belongs to codereview.se — Timothy Truckle 6 secs ago
 
They probably use a slightly different but related method for the really deep ones.
You usually don't need buoys in places that deep, so it doesn't happen often.
 
What exactly is the issue? If the code works as expected but you are just after some performance improvements or optimizations, you might be better off checking in with the Code Review stack. If you're worried about the math of the time difference, that's just straight reading the documenation to know what the output of Now - datTimestart is and debugging — Hursey 11 secs ago

Q: detection the selfish node Using awk File

I was going to say, that those buoys aren't anchored 16000 feet deep
 
I am having a bit of an argument with the author of Wrap to a certain column N. First I complained because an obvious typo, then I realized that there are many syntax errors, to that the code cannot compile. The author argues that it is from in interview where you had to write the code on a piece of paper, without the help of an compiler. – Any opinions how to handle this?
 
> The buoy team at Florida Keys National Marine Sanctuary has installed and maintained buoys as deep as 130 feet and as shallow as 2 feet. Recently, the team made history when they completed the working dive with an all-female crew to 97 feet to reinstall a mooring buoy on the bow of the U.S. Coast Guard Cutter Duane.
@MartinR interesting...
 
@MartinR My, possibly cynical take, is we're not in an interview now... I'll read the comments and such now
 
@MartinR I'd say that just because that is what they handed in at the interview that doesn't make the question on topic here.
 
9:05 PM
I hate interviews where they tie your hands and tell you to write code
I would ask them, is this how I am going to be writing code at your company?

one place I interviewed at, we talked through how we would write the code and the reasoning. the question for the code was taken at random from CodePex or something like that
Pexforfun
which is no longer a site....
 
@MartinR Closed. I think the comments can stay for now. I'll clean everything else up if the OP fixes the code. I don't know Objective C, so you happy for me to ping you if the OP edits the code and I the question looks fixed to me?
 
@Peilonrayz Sure. I'm “following” the question and will check possible updates.
 
Nice, thanks :D
