Q: How bad is it calling println often than concatinating strings together and calling it once?

CeleritasI know output to the console is a costly operation. In the interest of code readability sometimes it is nice to call a function to output text twice, rather than having a long string of text as an argument. For example how much less efficient is it to have System.out.println("Good morning."); S...

Q: Extend to Palindrome (SPOJ) giving WA

dabangg.boyHere is the Problem Extend to Palindrome Problem code: EPALIN Your task is, given an integer N, to make a palindrome (word that reads the same when you reverse it) of length at least N (1 <= N <= 100,000). Any palindrome will do. Easy, isn't it? That's what you thought before you passed it on...

 
blah, edited in copy and swap into my post, now it really is a wall of text
 
@Yuushi Yesterday's LL question?
Ah, okay
 
yeah
 
I should maybe start doing copy & swap in my own code. I haven't tried it out yet.
 
12:26 AM
its been quite a while since I've actually written a class that has done any kind of low-level memory management
generally, pointers -> std::unique_ptr (or shared_ptr if it has to be) -> use either default or delete for move/copy constructor/assignment
technically some of what I've written is only true if swap is noexcept
but blah, too much detail
I'm trying to not frighten people who are newer to the language away
I think Loki sometimes piles too much on too quickly
 
I probably could've also mentioned in my answer that key is unneeded for such a data structure. Luckily, it appears that the OP figured it out himself. I'm just not sure if he found my answer useful enough (and it didn't help that I possibly mislead him about std::unique_ptr).
@Yuushi Well, Loki has scared me a bit in my first question ("I would never use this unless you fix it first"), but it didn't get me down. :-)
At least I no longer code like that. Yuck.
 
haha :)
 
Still, I really need to catch up on C++11 as well as get a better understanding of multithreading. Luckily I'll learn just that (the latter) in the fall.
 
basic concepts of multithreading aren't so hard
it's ensuring correctness in larger code bases that becomes very, very diffuclt
*difficult
 
It may allow me to review more code, too. I do not want to be the weakest (regular) C++ reviewer here.
 
12:32 AM
reviewing it should give you some good practice to look out for certain things
when you learn about race conditions and deadlock, you can comb through code asking "does this code have a race condition? Can it suffer from deadlock?"
valuable practice
 
I think I recall what race conditions are.

Does anyone else think this appears to be example code?

@Jamal - it's probably on the wrong-side of A vs. B.
It's true that the code 'works' though, and, I was inspired by Simon's comment.
 
1:50 AM
@Jamal It's a great question, but it does seem to be an example. I hated to cast that vote.
 
I was about to close it myself, but it just didn't quite feel right.
 
I know, it was a great question and @rofl's answer was phenomenal, but we've closed questions that were less of an example.
Let it go through the review queue. That's why it's there.

Q: First simple program; counting button presses

thumbtackthiefThis is my first solo Objective-C program... it does the complicated task of displaying a button and counting how many times it's been pressed. It retains that count (along with the last time it was pressed) between uses of the app. I have a few specific questions, but eagerly await any and all...

Is there a way to mark all your @tags in chat as read? Accidentally left chat on from home while at work and now have like close to 30 tags
Oh, wait. That just did it right there. Great!
 
lol
 
@Phrancis How did you do it?
 
2:13 AM
I just requested in human language that it did, and it did.
 
If you type a message, it clears the notifications
If you have focus in the text-entry box, and press escape, it clears things too.
So, if I type @Phrancis ... and you type escape .....
 
Maybe I should look into more of this Human Language script...
 
@JerryCoffin - for you .....
 
Bleh. I want to do some coding but I gotta pack those stupid boxes.
 
@ckuhn203 You can still take your vote back if you'd like.
 
2:16 AM
@rolfl Awesome. I'd even seen that happen, but never thought of it as a way to clear the notifications. Thank you.
 
No problem ;-)
Unlike the C++ answer to the Java question.
Also, isn't C and C++ a lower level language than Java?
 
how...
 
Yeah @Mat'sMug. It's seeping in.
I know @Jamal, but right is right and I think it's example code.
 
@rolfl Although he didn't include either tag, his question very specifically talks/asks about C and C++.
 
@rolfl I'm not sure if they're lower, but they are low.
 
2:19 AM
@rolfl C and C++ certainly are higher level languages than JAVA
 
hehe.. the other day I reviewed a piece of and refactored it.. and kept adding semicolons everywhere...
JAVA is on another scale I think.
5
 
@rolfl Sun always sold Java as being higher level--but I see little in the way of higher level abstractions to support that contention. It is true that Java is more limited in how low of level you can go if you want--but it's also true that it's much more limited in how high of level you can go if you want (and also how high of level you get by default).
 
Lol. I'm trying to talk my tower into c#. We have the option of using either with the new software.
 
@Phrancis Are you saying that Java is closer to the hardware than C?
 
@ckuhn203 I find the VB syntax bulky and annoying
 
2:21 AM
No, I have no opinion on that (because if I did it would likely be wrong). Just a comment about JAVA.
 
Just going to use some mod privileges here...
 
The funny thing is, I hate semicolons. Now I'm unconsciously typing them everywhere.
 
Never mind, I realised that you're talking about JAVA, which is not a language I know.
 
@ckuhn203 you forgot the grammatically correct semicolon after the word, "semicolon".
 
nah, the funny thing, is that you're going to end up luvin' those semicolons ;)
 
2:22 AM
Next thing you know I'll actually be using them in my TSQL like I should be.
2
Dang... Thanks for pointing it out @Phrancis. I'm mobile so I can't edit it either.
 
@ckuhn203 watch the battery!
 
@ckuhn203 MySQL one of the few redeeming facts is it won't take your script unless all the semicolons are in the right place. TSQL will gobble up pretty much anything, semicolons or not. That's why real pros use MySQL </sarcasm>
 
Lol @Mat'sMug.
M$ is supposedly moving that way, but I doubt we'll see it. Too many backwards comparability issues for their taste @Phrancis.
I think we have a new faux tag.
 
@rolfl C and Java are about tied. C does allow you to speak more directly to the hardware, but really doesn't require it. With C++ you can write just as low-level of code as you can in C, but you can also write substantially higher level code--template metaprogramming, in particular, is much more comparable to something like Haskell (in fact, it's almost isomorphic to Haskell, though with much more verbose syntax).
 
* googles isomorphic *
 
2:28 AM
@rolfl should I accept your answer now or wait a little more and see what we get?
 
Oh. Makes no sense at all. Eyes glazing over.

@Phrancis It has been implemented, if that's what you mean. No, it's not really intended to be used to write anything useful though.

@Mat'sMug I thought that said sometimes insanity there at first
 
haha
so, rules
1. you need to include a link to the SE question you're basing your code on.
2. you may grab code from Programmers, Stack Overflow, Code Golf, ...anywhere code is involved on SE.
3. you have to prettify it - solve OP's problem, in a beautiful way.
4. you create a new CR question tagged , with your new code.
5. vote.
thoughts anyone?
@rolfl is that what you had in mind?
 
@rolfl Looks good. If/when I get a chance, I'll add some numbers to my answer as well.
 
@Mat'sMug @Mat's, the concept was fairly 'flippant' when it came up. Yes, that seems reasonable.
 
3:02 AM
Oh, have you tried getting numbers with the output directed to a file instead? That seems more useful than just throwing the output away completely.
 
Let me thing for 30 seconds.
 
@rolfl Time's up.
Alex Trebeck is disappointed that you not only failed to answer in the allotted time, but then forgot to phrase your response in the form of a question.

You're right... @rolfl what did I do wrong on [Post Link]?
@Mat'sMug can you think of a good arbitrary number for views? Or should I subquery to find higher-than-average views (slow)
 
nah, go with badge thresholds
 
?
 
25+ votes is a silver badge
10+ votes is a bronze badge
100+ votes is a gold badge
 
3:58 AM
That makes two of us..
So, short question, with high vote answer is what you're thinking? Or high vote question?
 
views is 1K for bronze, 2.5K for silver, 10K for gold
not sure about that criteria
both?
 
I think high views would be most entertaining
People on SO glancing it over and are like that and move on to the next one
Thoughts @Mat'sMug ?
 
if the code is horrible in the question, it's not likely to get lots of votes, even with lots of views
I'd think
 
Let me have a smoke and then we'll try it out. That is, if my wife doesn't kill me because I should be packing boxes. lol

At last I have to step into the horrendous world of Javascript

@JeroenVannevel JS is awesome, I don't know what you're talking about.
 
Damn Web-"Developers" ;)
recently read a job-offering on careers:
 
@Vogel612 Damn JAVA "Developers"
 
> If you think, JS is more powerful than Java
and I was like, get lost!
 
functions in functions, dynamic objects, weird-ass equality operators
 
6:46 AM
@Vogel612 JS is not more powerful than Java, but it's a whole lot more fun.
 
That's no thing to develop with
 
@MadaraUchiha damn right, damn JAVA-Developers.
I am better with Java
 
@JeroenVannevel functions in functions is an incredible feature. And if you enter JS it's a good thing to learn.
dynamic objects is a bit weird, but if you're used to NoSQL you'll have a better time.
You can have === which is the "exactly equals" in contrast to =='s "probably equals".
@Vogel612 I'm good with both. JS is more fun.
I don't want to define a whole class just for an event callback! That's not how the real world work!
 
Yeah, but === has all kinds of unintuitive results when used with different values of different datatypes
I've seen the weekly popular topic in the JS corner
 
@JeroenVannevel No, actually, === is perfectly intuitive.
 
6:48 AM
always some strange behaviour with ===
always
 
== is weird, === isn't
Also, I don't count undefined behavior as "weird", it's undefined, don't use it.
 
[] + [] --> ""
[] + {} --> [object Object]
{} + [] --> 0
{} + {} --> NaN
 
@Vogel612 That's not ===
And why the hell would you want to add objects/arrays?
Show me a real world case where behavior is weird.
PHP has plenty of those, I know :P. I have yet to met it with sane JS
 
@MadaraUchiha that behaviour is even defined

7:03 AM
@Vogel612 Maybe, but it's not something you would use in an application.
 
@MadaraUchiha heard of obfuscation? I would bet someone somewhere used this to obfuscate a codesample.
 
to be fair, you can write obfuscated code in any language
 
@Vogel612 I generally don't obfuscate my code.
My assumption is that if someone is good enough to follow my incredibly abstracted code, he can use an unobfuscator or read obfuscated code.
 
@Yuushi but only JS allows that exact obfuscation
 
@Vogel612 obfuscation is a hack to try and protect something that can't be protected.
Only stupid people obfuscate their code (differentiate "obfuscate" from "minify")
Obfuscation cannot and will not protect your code from prying eyes. Here's a nice example to prove my point:
 
7:11 AM
@MadaraUchiha I can't agree. Only stupid people think obfuscating their code has practical use. Some people do it just for fun though. ioccc.org
 
@JerryCoffin Yes, that is what I meant.
Doing stuff "for fun" or "for learning" is never stupid
That doesn't mean you need to take a theoretical concept and force it on real-world scenarios.
