The 2nd Monitor

@IsmaelMiguel Duly noted.

Now, can you explain to me how it is worst than the other question? So I can finally understand everything?

No. It's been explained several times in chat before and I'm not wasting more time on this if that wasn't sufficient. I'm not that invested in this discussion.

You haven't explained it even once.

Maybe I need that code so it can brute-force the meaning out of your cryptic messages.

Stop arguing about the end of the argument. I'm trying to get my first CR answer in 2 months out.

6:06 PM

I'm not even arguing

just... stop...

Yeah, I give up. This really is going nowhere.

Problem solved

Is it appropriate to edit someone's question to clean up code formatting (align indents, remove excess whitespace, etc.)?

Yeah, I think it is

As long as you don't change anything else

No

6:18 PM

I think I did that in the past

It's not appropriate.

The only time it's appropriate is if it's clearly a problem the user had copy & pasting from their IDE.

Yeah, he is right

Changing the whitespace will change the answers

Because now you can't comment on the indentation

Even if there are no answers yet, making that change for them means they can't be reviewed on that problem.

And it is a problem.

Alright, well I'll not do it then.

Exactly

But I think that it is somewhat fine in an answer

6:20 PM

@nhgrif I was speaking on behalf of this question which is very unreadable in it's current state, but I'll just copy/pasta it in VS, and then format it so I can read it before answering.

Especially when you get to the end of the code block.

And the last, 15 or so lines, are whitespace and two end-braces.

@EBrown Can you provide a pastebin, so I can read it as well?

@IsmaelMiguel I'll provide it as an answer, so that everyone can read it.

That would be amazing

@Malachi Sounds more like a call for an upvote brigade on a particular Meta post. Sounds iffy to me.

Q: Mancala in Objective-C

int.TryParse(Regex.Match(cmd, @"\d+").Value)

This is just.. int.TryParse(cmd), right?

What's that Regex doing in there

Well, the .TryParse is redundant really.

The Regex filters out numbers.

6:27 PM

@CaptainObvious wat

You could just: Convert.ToInt32(Regex.Match(cmd, @"\d+").Value) and it should have the same effect.

"in Objective-C" tagged C++11

Yeah, int.TryParse(cmd) seems prettier to me

That's not the same though.

As far as I can tell, it does have a different effect in certain cases.

Oooh I see, he wants to validate after stripping it out

6:30 PM

(I could be wrong, though)

Yeah.

He wants to pull out numbers from the cmd, then turn it into an int.

If only numbers are left then you might as well just omit Try and just int.Parse it

Or Convert.ToInt32.

Either works. :)

Though replacing TryParse with Parse might make it faster.

This code reads an image and detects a shortest path using Dijkstra's algorithm from each point on the top row to its corresponding point on the bottom row.

Anyone here know enough of C#/.NET to be able to tell me if there is a better alternative to having two Dictionary<char, char> properties?

Each one has 6 objects within it.

@EBrown what are you doing?

@EBrown Is dictionary a hashmap ?

Transposing certain characters for numbers.

public static Dictionary<char, char> NumberToLetterMap { get; } = new Dictionary<char, char>() { { '1', 'i' }, { '3', 'e' }, { '4', 'a' }, { '5', 's' }, { '8', 'b' }, { '0', 'o' } };
public static Dictionary<char, char> LetterToNumberMap { get; } = new Dictionary<char, char>() { { 'i', '1' }, { 'e', '3' }, { 'a', '4' }, { 's', '5' }, { 'b', '8' }, { 'o', '0' } };

Those are the two Dictionary<char, char>'s.

Can a dictionary have more than 2 values?

7:33 PM

@JaDogg yes, but in worse

why is it <char, char> and not <int, char> I suppose

Because I process the numbers as characters.

The programme walks through a string, and for each character does things.

@IsmaelMiguel <char, char, char> would be a tuple

Alright

I'm thinking

lol nevermind that monitor thing

7:34 PM

If the character can be replaced for a letter (if it's a number) or a number (if it's a letter) then it will make the appropriate replacement for sake of processing.

@Vogel612 you plugged it now >

if (NumberToLetterMap.ContainsKey(currentCharacter))
    currentWord += NumberToLetter(currentCharacter);

Frankly, another person on CodeReview told me that the above program was O(256). If it is not, you may edit the post accordingly. — Darth Shadow 51 secs ago

^ That happens for a number.

Wait

7:35 PM

isn't there a hashset ?

You are writting in 1337!

It supports parsing l33t, yes.

> A char can be implicitly converted to ushort, int, uint, long, ulong, float, double, or decimal. However, there are no implicit conversions from other types to the char type.

@JaDogg nope.. restart

I'm just curious if there is a faster way to do that bit.

7:35 PM

@Vogel612 LOL :D

Still thinking

And if it's a letter, this happens:

if (LetterToNumberMap.ContainsKey(currentCharacter))
    consecutiveNumbers += LetterToNumber(currentCharacter);

(More stuff happens than just that, but that's the basics of it.)

@JaDogg What's that good for?

How about 2 arrays?

no

Dictionary is better than 2 arrays

7:37 PM

I already looked into that, it was slower performance-wise.

actually that depends...

Q: Is there a better way to toggle a logical NOT operator based on a boolean value?

the lookup time is faster for large enough Dictionaries, but you may lose that benefit from the key acessing for very small sets

@CaptainObvious Needs a title.

@Mast Oogah Boogah is saying Hi

7:39 PM

Spam.

@CaptainObvious Is this off-topic? "This is of course only an example, ..."

I have an idea

If it is the hash set I didn't see { '1', 'i' }, { '3', 'e' },

@EBrown To get a number, try <char> % 3

It isn't perfect

@IsmaelMiguel How does that help me at all?

7:40 PM

It works for i

Which returns 1

And e, a, s, b, o?

It works for o

Which returns 0

@SirPython Not every post with the word example in it is example code.

Which should be 3, 4, 8, and 0?

But I'm experimenting

7:42 PM

It needs to be fast, and allow me to swap between the two with ease: 1 -> i -> 1. Which is why I used two (small) dictionaries.

I was curious if there was some odd collection out there that did what I wanted.

@SirPython He edited the title but it still isn't right...lol

@Vogel612 Do you think a switch with a method would be the trick?

@EBrown might be worth condsidering, but a dictionary is somewhat cleaner for a lookup-replace

depends on how desperately you need speed, right?

That's what I was thinking, and I also have to be able to determine if a character is a valid replacement character.

I.e. if you pass 6, it should not even attempt to replace it.

@EBrown I've found something weird

letter -> ASCII code

There's no fast type of collection that handles a key-value-pair like that and allows me to lookup either key or value from the other?

With speed, that is.

If you go from 97 to 98, it is 1 of difference

If you go from 98 to 101, you will notice a pattern

01, 05, 11, 15

7:47 PM

And what would you suggest I do with that information?

Now you have 1,5,7,8,11,15

@Vogel612 Unfortunately, I need a great deal of speed. :P

@EBrown then use a profiler and don't ask random people on the internet :)

on a related note: I'm not a performance specialist, far from it actually

Well I wasn't asking so much about the switch specifically, but a profiler doesn't tell me what built-in objects might have more appropriate functionality/speed for me. :P

Unfortunately only people know whether a HashSet, List, Dictionary, or array is appropriate for something like that.

I can't activate my windows 10 because I actually installed it manually instead of waiting for you snails to clean up?

Oh wow.

Because ... WHAT?

They be like: "Sure you can install windows 10 anytime you like"

and afterwards after reading the microsoft help center for some ... half an hour or so it's:

"No you can't install it yourself... well you can, but only after we installed the upgrade from windows 8.1"

@Vogel612 Are you using the Windows Media Creation Tool‌?

yes I did use the media creation tool

ERMAGHERD

brb downloading 8.1 ISO to do the effing upgrade..

because that's not totally surreal...

and they should have made that disclaimer in red...

Strange... I upgraded to Windows 10 manually, but that was on a PC from Windows 7

None of them were OEM versions, not sure if yours is?

8:15 PM

but you didn't do a clean install?

I went 8.1 -> 10.

Ah no, I did an upgrade

well there's the explanation

For a clean install you'll first need to upgrade and then need to clean install

yep. I didn't.

Also, youtube.com/watch?v=Bo-qweh7nbQ

At least that's what I understood from the documentation

in Windows terms I'm a user

users don't read documentation

@Vogel612 How did you manage? I was under the assumption that Microsoft made it "impossible" in order to prevent accidental wipes

was easy.

@skiwi First upgrade, then clean install? That doesn't sound clean at all.

8:16 PM

@skiwi That messed up for me. After I upgraded and started the reset, it screwed up somewhere in the middle and my computer was left with nothing on it at all.

Windows Media Creation Tool, Create USB Drive, and then standard stuff

Hmm... right, you can download a Windows 10 ISO

not even that

I used that official thingie, with the purple background

I don't know exactly how I did it, the upgrade was preloaded on the W7 PC, but did use the media creation tool, and then it did upgrade suddenly after downloading it again

All of the thingies have the purple background.

8:17 PM

I didn't even get to that help page

@Vogel612 I believe that if you are going to do it that way, you are going to need to enter a product key somewhere in the middle, unless you've already activated W10 on that computer before.
