12:33 AM
As someone sitting at 3404 rep, I'm now jealous of you 3500-club members :-(.
Wow, rolfl, your rep graph makes me sad inside. You've been busy!
 
@Corbin: Tell me about it...
But at least now I have enough rep to cast close/reopen votes for post-graduation.
 
12:53 AM
@Corbin - Funny, i have been using CR as a diversion... I have a ton of real work to do, and I'm putting far too much time in to it... but it is interesting, and challenging... I am using CR as a distractin 'to take my mind off things'.
Until the past few days I have not really been trying too hard... just getting lucky.
 
quite a lot of distraction then! or youre an extraordinarily fast review writer :).
 
I figure I can do 3, maybe 4 a day. at about a half-hour each... and I have to work at least an hour before I do another one.
Given that I am doing at least 10 hrs of ork a day at the moment, this is OK.
I also toy with some things during boring meetings ... ;-)
The ones that took real time are ones where I have learned something like:

A: Find elements occurring even number of times in an integer array

rolflWiki Answer - discussion of scalability. After some investigation I thought it would be interesting to publish some of the performance results I have seen.... there are some interesting observations. I have taken two algorithms, both on this page, the 200_Success one, and the rolfl one. I have ...

 
Well, as I've already mentioned, I'm spending more time here than I am studying. When the decision is between programming and stats, there's no contest.
 
And that was worth spending the time on to get somrething more than a distraction out of.
At some point I am going to trace and profile that code, and fogure out why there is the dip in the one curve, and why there is inverse scalability on the 'medium' density duplicates.
I can take that data to the lead Java developers @work and probably affect future product performance.
 
1:14 AM
i usually use CR as a distraction too. 1.5-2 hours a day though? nice
 
Only because I'm putting in far more actual work ... ;-) Anyway, my review of @SimonAndréForsberg code is taking far too long... it's more than I have time for .... time for a half-arsed job.
 
It must be great being an SE employee. They actually have an excuse to spend all day on SE sites and get paid for it.

@rolfl: Relevant to your interests:
Grace Murray Hopper (December 9, 1906January 1, 1992) was an American computer scientist and United States Navy Rear Admiral. A pioneer in the field, she was one of the first programmers of the Harvard Mark I computer, and developed the first compiler for a computer programming language. She conceptualized the idea of machine-independent programming languages, which led to the development of COBOL, one of the first modern programming languages. She is credited with popularizing the term "debugging" for fixing computer glitches (inspired by an actual moth removed from the computer). Owin...

@rolfl DING! (Once again, when you least expect it)
I think I will add some comments on your answer to explain some of the things you didn't understand about my code. But I do admit, you have many good points in there.
 
I have reread my comments, and your code, and some things fell in to place as well.
 
If I am brutally honest, part of the problem was just too much code. If it is in eclipse where I am familiar with jumping through method calls, hitting f4 for hierarchy, f3 to open methods, etc. it would have been easier to work through.
Anyway, the 'flat' layout for CR does not help much when it comes to 'feeling' the inheritance, etc.
 
Yeah, I agree. It's much harder to get a good overview of code on CR. I should have included a link to a .zip to make the code easier to download, since there is no copy code button

@SimonAndréForsberg what zombie?
 
@Malachi At first I thought "Why are you asking me? It's a C question! Both I and @rolfl are Java guys"
I'd say that's a significant improvement to the answer indeed. Upvote from me
 
@SimonAndréForsberg thinking about that. couldn't we create a 2 dimensional array and see if it adds up to 45 in each row, and then check that there isn't a duplicate digit in a row or column? all at the same time? I forgot about the 3x3 blocks too....
 
@Malachi Just because it adds up to 45 doesn't mean that they're all unique. 9+9+9+9+1+1+1+1+5 is also 45.
Or even easier example: Fill the entire row/column/box of 5s, 9*5 = 45.
Oh, you mentioned duplicate digit also... gotta learn to read first and write later.
But if we check for non-duplicate digits, the 45 check is redundant. Assuming we also check for non-empty and enforces the digits to be within the 1-9 range.

@SimonAndréForsberg the other thing that I remembered about Sudoku is that you have 3x3 blocks that cannot contain duplicates as well as the entire row or column cannot contain duplicates. there's the rub.
@SimonAndréForsberg do you have a downvote on that question? you can remove it if you do.

@Malachi I'm downvoting it because it's both unclear what he's asking and he doesn't provide any background information. I won't vote to close for the moment though. See my meta question.

@Jamal Actually, I think that might be a bad idea for the Code Review site in general, for the same reason that we have a no-pseudocode rule. Here, we like to critique code that solves a particular problem. For generic best-practices questions, there's Programmers.SE.

tomdemuytPlease see this question : refresh a page without reload in php? I invited the 2 users to comment on this thread. From my perspective, Code Review is there to Review working code, that code is not working.

 
@200_success: We can clean them together, then.
 
does this answer strike anyone else as odd: codereview.stackexchange.com/a/36980/7308 In particular, it feels like he is suggesting a modification of a service locator, which is well known antipattern. And the m_ or m prefix seems to be useless in a modern IDE. Not to mention, if there's so many variables involved that local/class mixups are happening, it's a huge code smell in my opinion that the class is holding too much state and thus likely doing way too much. Any thoughts, anyone?
I'm just worried that I'm missing something, since it got 4 upvotes in an hour >.<
 
You could mention that all in a comment.
 
8:15 PM
yeah, i considered it... but just wanted to double check my understanding before. it's very possible that i've misunderstood something about the entity manager that he's suggesting
 
Where's Loki when you need him? ;-)
 
really :(
lol
this is actually a trend ive been meaning to write about on meta for a while but havent gotten around to. on this answer it's not really a big deal, but on quite a few PHP answers there is some less than great advice, but the answers have been upvoted...
i think it's an underlying problem of the site: if anyone can vote, then people who aren't always qualified to vote can vote...
it's a very, very minor problem over all, but just something i've come across a few times
although on this C++ answer, I suspect I've just misunderstood what the poster meant
 
True. That cannot quite be stopped, though, as votes are anonymous.
 
@StackExchange Yeah, I was under the impression that was like Rule Number 1, so their unhappiness is unfortunate but irrelevant.
 
@Donald.McLean: Agreed. Guilt shouldn't get in the way of this, especially if the OP has other options. I also think it received those downvotes because it was hard to understand the question.
 
8:25 PM
i think it received the downvotes because not only was it off topic, it was a bad question.
it would get downvoted and closed on SO too which is where it (arguably) belongs
 
@Corbin: Hence why I didn't migrate it.
 
:)
whoa i just realized that meta is hidden in the help menu of the new top-bar. that's interesting
 
Gotta remember that golden rule. And... although SO occasionally sends us off-topic questions, it doesn't mean we need to fight back.
 
I wasn't saying that you should migrate it. I was just saying that it could, in theory, with a lot of improvement belong on SO :)
 
True, but that may be up to the OP to improve it. Perhaps it'll get posted there anyway.

Q: Optimize this path location script?

Clark T.Example Script is located in /home/insp/public_html/deploy/ I want to return the /home/insp/ section $path = realpath(__DIR__); $parts = explode('/', $path); $newPath = array( $parts[0], $parts[1], $parts[2], ); $realPath = ...

 
@Jamal So we want to abolish , currently with 15 questions. A lot of those questions are old. Would pushing them to Programmers.SE be considered "migrating crap"? How about just closing/locking them?
 
right. i wasn't implying any of us should improve it. just that's it's a rubbish question and it doesn't belong anywhere.
 
@200_success: They are all too old to migrate. I'm cleaning them up now. Some, particular ones without code, have been deleted. I've noticed one that has specifically mentioned pseudocode. I may delete that one, or lock it. As for the rest, the tag can be removed. Again, watch out for pseudocode.
 
@Corbin FWIW, I upvoted that answer.... It appeared in my 'First Post' review queue, It looked like the answer tackled a specific problem in the question, and then gave general, and reasonable advice to the asker... I upvoted when the guy had rep=1. In general, on CR, I have the impression that we should be generous with upvoting (and down voting)
 
@rolfl Hmm. The m and m_ prefix thing is definitely valid advice, especially since he presented it in the context of personal coding style. Even the EntityManager is understandable if the 3 objects will never be in a situation where all 3 are not needed.
My fear though is that the EntityManager will quickly devolve into a "Oh the PaddleDrawer needs the enemyPaddle? I better pass it the entire EntityManager and just have it draw both at the same time" situation. Perhaps I'm just being overly picky though, especially for a first answer.
In the right context, the EM can be valid advice. I just think in 99.9% of cases, it's dubious advice at best, and the answerer didn't explain that. EntityManagers have a bad habit of permeating through an entire code base once one is introduced.
 
8:51 PM
@Corbin you may well be right, and I think this is the danger of getting all first posts in the review queue ... I simply do not know C++ well enough. I simply went on a 'triage' system: If the post has spam/whatever I downvote and close. If it looks loosely on topic, I say 'looks good'. If the answer looks well thought out, on topic and like it adds value, I upvote and Done... This answer ranked upvote. If the topic is one I am more familiar with (Jva, SQL, whatever, I pay more attention).
 
Fair enough. I tend to use a relatively similar approach when I'm in the first post review queue. I actually hadn't considered the first post aspect of it.
 
@200_success: I've edited a few myself, but I'm not sure of their languages. Some don't seem they should be deleted, though.
 
9:08 PM
@Jamal I don't think codereview.stackexchange.com/q/1586 should have been closed, since the code can be improved, and reasonable justifications can be given. It should also be tagged with .
 
@200_success: Okay, I can make some improvements and reopen it.
 
heh... apparently I have fuse:

A: Improve code performace

rolflYour code does not work... submitting here just because it compiles is wasting our (my) time. In your code you have: dataReader = new BufferedReader(new InputStreamReader(new FileInputStream("subDirs/status"))) This is a broken line, and it will obviously not do what you think it should. So,...

I am really getting tired of seeing bad titles...
Lesson to be learned here: don't waste the monkey's time.

Well, every site needs a coding monkey, and we have ours.

Charlie74Long story short, I have a social networking site I wrote a while back as a "proof of concept" to myself that I had the skills to do it.

@Corbin: I eventually found it after going through some digging. :-)
@200_success: I've just noticed the OP's username. Brix = shat.
 
9:51 PM
interesting. i guess not very surprising since there is still a surprisingly high amount of cobol out there, but still... interesting
 
There are still many questions on SO, but unfortunately they're only on-topic for that site. I would've loved to see rolfl earn the bronze tag badge.
 
yeah
somehow i imagine there's a pretty small interest in having COBOL reviewed since most code bases using it are 10+ years old
 
Speaking of tag badges, I'm surprised you haven't earned yours yet for C++.
 
it would be a very uphill battle to try to refactor a cobol code base now. especially since if you're going to go through the effort of refactoring it, you might as well rewrite it in a modern language.
27 points from C++ bronze it looks like
 
Yeah. Clearly tag score isn't everything, as I'm pretty sure I'm not the 2nd-best C++ reviewer on this site (based on skill, not activity).
 
9:59 PM
eh i think youre pretty good
Loki just sets a really high bar :)
there's a actually a lot of good C++ reviewers. I've learned a ton from reading random C++ reviews. Every time i write one, there's this nagging voice in the back fo my head that's like "there's at least one thing wrong in this, and someone will find it" lol
 
Really high. :-) Winston Ewert is great as well, but his modding had to come first (and he now does Python). There's still lots for me to learn, and I'm so glad I've discovered SE. It has probably changed my life.
 
yeah
i cant imagine where my C++ would be if not for CR...
C++ is possibly one of the top languages in terms of widely misused
 
Yeah, there are random ones, but it's good to know what the "established" ones are. That, it seems, is based on tag score.
 
whenever i see classmates' C++, i typically cringe
raw pointers, loops instead of standard library stuff... undefined behavior... all kinds of "ohhh god!"
yeah, im sure tag score correlates pretty closely with skill
 
Back when I took my first data structures class, I sucked. Made an F, despite great honest effort.
 
10:02 PM
it's obviously influenced by output, but... definitely corresponds with skill
i loved data structures. advanced data structures is the class that made me actually learn C++. pretty hard to implement RB trees, AVL trees, hash tables, vectors, etc without learning some of the C++ gotcha's and tricks
not to mention that was the first time i ever looked at the standard library and actually thought about why they made the decisions they did rather than just how to us eit.
use it*
 
Well, back then, I was still bad with C++ classes. I remember once telling another professor that this seemed like something I could never understand. And yet here I am...
Oh, and have you seen this?

A: Review of three constructors for a String class

JamalWhen dealing with length, prefer std::size_t. This is an unsigned integer type that is also the return type of the sizeof operator. It is not good to use int because you cannot guarantee that any length will fit. Your code will break if the user constructs an object that is too large. There's...

 
i actually saw that in the going native videos
it's been at the back of my mind for a while
i still tend to use std::size_t probably more than i should
it's just so temptign to have everything mesh well with the standard library :(
im glad you posted that. i need to go back through and edit all of my answers
that was always one of the things i would pick on
 
Agreed. I still admire the STL, even in spite of this. Not sure why it took them so long to discover this, though. Might be a good reason.
 
eh, they had good and understandable intentions
"a size should never be negative" seems like a good enoguh reason
it's just through C++ funness that void f(unsigned int x) {} f(-5); is valid code
and thus invalidates that reason
idk. in C++11 it's much less of a concern, but in C++03, i'm always tempted to use std::size_t for loops since gcc/clang both get pissy about for (int i = 0; i < v.size(); ++i) {}
 
Yeah, that code is just asking for bugs.
 
10:12 PM
though lately ive begun doing: for (int i = 0, s = v.size(); i < s; ++i) {} which does not give warnings
 
Even in that code, std::size_t is not preferred as you cannot assume the container uses that size type. It is, however, preferred for C-style arrays.

Q: Help me optimize this scrollTo javascript

user1087110I'm no pro in Javascript. Please help me review this code. I would appreciate any suggestions! Javascript: var y_offset, /*current position of window*/ distance_from_current_position, /*different between current position and target*/ body_height, /*hight of body*/ window_height, /*h...

 
well, yeah. if i were going to be very pedantic, i would use vector<...>::size_type
but that presents a problem of hard coding that v is a vector
which should typically be avoided
all the loop needs ot know is that a size() exists and that an operator[] exists. having vector::size_type in it presents a new coupling
 
What about a typedef?
 
though it's obviously very, very minor
well, if i go the ::size_type route, that's what i usually do. it still presents a problem of having the type of v unnecessarily involved in the loop through
though*
idk... just another reason to prefer iterators :)
(well, and im crazy)
 
10:16 PM
True. :-) I suppose in the case of keeping a number count, a separate counter could be used.
Speaking of iterators, I still haven't been able to fully access C++11 on my machine. I do want to start using range-based for-loops.
 
if the numeric index were involved, i would probably just go ahead and use for (int i = 0, s = v.size(); i < s; ++i) {}
why isn't it available?
C++11 is magical. it feels like a different language. it's great.
 
It says my gcc version is 4.7.1, but also my IDE (Visual C++ 2010 Express) cannot utilize all of C++11.
 
you're using VC++ with gcc? that's interesting. you could use netbeans to get access to C++11 with 4.7, but... meh.
you could also go the dreamspark route to get VC 2013 for free
 
Frankly, I'm not too picky with compilers. I just haven't found an ideal one.
 
ive begun using clang lately. it supports all, literally all, of C++11, and it tends to have better warnings than gcc
it's mac/linux only though unless you're willing to get your hands very, very dirty trying to get it to work on windows
 
10:23 PM
I can consider Visual Studio, but it'll probably take some time to install it.
 
i remember mingw having some oddities with gcc 4.7, and C++11 but... maybe that's fixed now
idk. you could also try netbeans. i tend to use it for C++ when im on windows
 
I can give it a try. I'm also having to get my make utility working so that I can run x86 assembly programs again.
 
ah
 
I wanted to write a FizzBuzz program in assembly. :-)
 
that could be interesting
which instruction set?
 
10:42 PM
8086, I believe.
This is the type I was taught in my assembly class. I've also covered MIPS in another class, but it wasn't an assembly class.

Q: Making .NET delegates and C++ std::function play nice

goneskiingSo I have a question about how best to get interop working between delegates and unmanaged std::function. Obviously I am talking C++CLI for the implementation on the managed side here. Most examples I have seen online talk about interop for stand alone unmanaged functions and also often with no...

 
I didn't do a Degree where they taught people enough to be programmers. I never learnt to write assembly (among other things) I didn't get my job because of my awesome education. Must have been my good looks.
 
my degree has been 99% theoretical, but i was originally computer engineering before computer science
and we had a class that was processor design and assembly
 
I live in Australia where (IMHO) that we don't have much in the way of good education for software development. I did learn a lot of other things like how to write an essay and business report. How to set up an old-school router/network ports. And how to write copious amounts of documentation so that no-one will read it.
Thankfully I enjoyed programming and was learning before I got into my tertiary education.
 
hrmm in america, CS degrees don't focus on software development at all. it definitely comes up in passing, and most schools have at least 1 or 2 required courses on it, but... meh. 98% of the people about to graduate with me i wouldn't want within a hundred yards of a code base i had to work on.
typically software engineering is seen as a separate degree here
or it's not offered at all...
was your degree IS or CS, out of curiosity, James?
 
11:22 PM
Ok ... so I don't feel so left out then.
 
because it sounds like an american IS degree
 
It was a Bachelor of Information Technology. The coourse was retired after my year and they now focus more on Non-Programming units.
It covered a little bit of everything and not enough of anything to be helpful.
 
ah
IS degrees in America tend to go into more of hte business side than the actual technical side
for example, the IS degree at my uni is actually though the business college, not the engineering college like hte CS/CE degrees are
not sure if it's like that there though
 
I've given up hope for any real software developers to come out of uni with some solid grouding. I think its more important to look for a learning attitude and teach them on the job.
I think CodeReview and SO are better teachers.
 
does this code work now?

Q: Two functions with different names but the same implementation

ROHIT NANDANBelow are two functions with different names but the same implementation. I'm getting different answers. Can someone review them? #include <iostream> using namespace std; int s[100],p[10]={1,5,8,9,10,17,17,20,24,30}; int max(int a,int b) { if(a>b) return a; else return b; } i...

 
11:31 PM
well, the problem is that most degrees don't try to teach software engineering. not to mention that most faculty have 0 software development skill. i don't expect CS graduates to have software engineering experience. it's not what a CS degree is. I'm not quite sure about IS, but i don't think IS degrees focus very much on SE here either. CS just focuses on theory.
i do wish it had dealt with SE a bit more though :(
 
@Malachi I can't see any code changes ?
 
@Malachi I voted leave closed
That is Jamal keeping house tidy
(He hates bad titles)
 
I had a couple of Lecturers that could program. One in the physics area (not corporate or industry) for things like a spectrometer monitoring software and other research tools. Another who was actually in the industry for many years (good old COBOL and c++) and what they taught us off the curriculum helped more than what we actually studied.
 
One professor I had was actually really good with C. There are a few other professors at my school who can actually code, but I've just seen their code; I didn't take any of their classes since they were both new this year. Most of my professors not only are bad at software engineering, but actually promote bad practices. It's very frustrating.
For example, one of my professors told the class that vectors in C++ are slow and that they should use raw arrays. Not only is that entirely error prone, but it's wrong. As long as the vector doesn't shrink or grow and the compiler is even vaguely recent, the performance will be identical.
 
@rolfl does it automatically get added to the reopen queue when someone makes an edit on closed questions? @Jamal

I believe so.

boboboboSometimes, when you're doing something like displaying a bunch of elements, you can avoid running a function entirely if an object is hidden. So you can either write the check from the loop: for( Displayable * d : displayables ) if( d->isShowing() ) d->draw() ; Or you can put an "...
