@Alfe Asking for improvements on existing code can make for very on-topic questions on Code Review, as long as it's not "I want to add feature X". In fact, questions as blanketed as "Here's my code, any suggestions?" aren't really that great on Code Review. — nhgrif 1 min ago
 
@JeroenVannevel Objective-C has done perfectly fine without method overloads for 32 years. Of course, there is implicit casting between lots of the primitive types though. You don't need a specific method for int versus long etc.

Have you seen the new-profile hack that's available for those "in the know" ?
 
@Duga I haven't seen these posts yet
@rolfl that is cool
where does that pop up from
 
If you go to your meta.stackexchange profile ......
then see this:
At the bottom right, there, there is a 'settings' icon.....
click that, and you see your badge progress.....
the logic that populates that screen is enabled on all sites, but the display is not.
The link above is the logic.....
when the new profiles get rolled out to CR, then the need will be gone.

Another code review note: You shouldn't call ballMove() inside a function named randomColor() because moving the ball has nothing to do with what the function says it does. Same for ballPosition() - you should set or return the ball position, not call randomColor() or add the balls object to the parent. Those functions should be handled by the function calling ballPosition(). — All about that base 2 1 min ago
Impossible to answer in an objective way. You tried to provide detail and explain yourself, but the questionS are subjective and broad. I can't recommend code review, either, because I don't think they get into large-scale reviews of pattern implementation. Check out their post guidelines. This isn't a Stack Overflow question, though. FWIW, MVC in the true sense is pretty much not possible in PHP. You're building an approximation. The most important things are having a coherent structure, separated concerns, and code you can test. You seem to be on that path. For more help, break it down. — Chris Baker 1 min ago

This problem is... counter-intuitive
The Monty Hall problem is a brain teaser, in the form of a probability puzzle (Gruber, Krauss and others), loosely based on the American television game show Let's Make a Deal and named after its original host, Monty Hall. The problem was originally posed in a letter by Steve Selvin to the American Statistician in 1975 (Selvin 1975a), (Selvin 1975b). It became famous as a question from a reader's letter quoted in Marilyn vos Savant's "Ask Marilyn" column in Parade magazine in 1990 (vos Savant 1990a): Suppose you're on a game show, and you're given the choice of three doors: Behind one door is...

@DangManhTruong your codereview question is a verbatim crosspost of this one. Additionally your code is rather much and the problem itself isn't an easy one.

It sounds like you want to improve your PHP script, but we'd need to see it in order to make suggestions.

@SimonAndréForsberg LOL. Now I did.
Isn't Open Office defunct now though?
I thought development was being focused on LibreOffice now?
TBH it's been a few years since I've looked at either.
 
@RubberDuck It is? I have no idea. I still use Open Office. Never heard of LibreOffice before.
 
I love how my machine is basically bricked while its installing about 20 different security updates this morning.
LibreOffice is a free and open source office suite, developed by The Document Foundation. It was forked from OpenOffice.org in 2010, which was an open-sourced version of the earlier StarOffice. The LibreOffice suite comprises programs to do word processing, spreadsheets, slideshows, diagrams and drawings, maintain databases, and compose mathematical formulae. LibreOffice uses the international ISO/IEC standard OpenDocument file format as its native format to save documents for all of its applications (as do its OpenOffice.org cousins Apache OpenOffice and NeoOffice). The OpenDocument file format...
> Oracle announced in April 2011 that it was ending its development of OpenOffice.org and would lay off the majority of its paid developers.[80] In June 2011, Oracle announced[81] that it would donate the OpenOffice.org code and trademark to the Apache Software Foundation, where the project was accepted for a project incubation process within the foundation, thus becoming Apache OpenOffice.
 
And Apache did not continue the development?

Greetings, Programs.
 
@Donald.McLean Greetings, User
 
12:57 PM
So, hey... @rolfl @Donald.McLean you guys have been around. Seen some things. Either of you ever worked with Serena Dimensions?
a.k.a. PVCS
Monking btw
 
@RubberDuck I have, a long rime ago
VB code at the time.
very much last century
 
@rolfl Is it as bad as the internet says it is?
I'm a bit skeptical of a system that locks files and has no merging ability.
 
@RubberDuck I've worked with quite a few technologies, but never heard of Serena Dimensions.
 
I'm trying to figure out how hard I need to fight for what I want here I guess.
 
@RubberDuck - No idea if it is as bad as the net says it is.
 
1:08 PM
I think it comes down to any source control is better than none, but what I've been reading has me thinking that might not be strictly true.
 
At the time, it was the first VCS that integrated well with issue tracking, and reporting.
At the time it was a step up. Hopefully they have kept up to date with the trends.
 
It doesn't seem they have, but I won't really know until I get my hands on it.
I was just wondering if anyone I actually knew had any horror stories.
Doesn't sound like you had an awful experience with it.
Which gives me hope.
 
I've only used two VCS technologies at work. CVS and whatever it is that works with Trac.
 
@RubberDuck At the time, any structure seemed like an imposition on my creativity...
nowdays I prefer to have the structure ;-)
 
Ahhh, to be young, and free ... and stupid.

1:12 PM
That ^^^
 
I'm just worried about bringing in too much over head. Too much structure.
So much of what we do is at the drop of a hat. Get it done yesterday.
 
@RubberDuck - prepare yourself to have a less-than-ideal setup with it.
 
Better than nothing I guess. Thanks for sharing.
That's exactly what I'm worried about...
 
but, note that the reasons for keeping it are often more complex than just your feelings
 
But why set up something brand new on antiquated VCS?
That bothers me.
 
1:15 PM
Specifically, often, the history stored in it, or the automated build process that currently works, etc. are significant investments....
 
Those don't exist.
Not yet.
I went asking for a VCS, (git) and they came back to me with this.
I'm just really frightened that I'm getting something that's going to make my work more difficult when I was trying to make it easier.
 
Often these kinds of decisions are made for no particularly good reason. "My cousin works for the company that makes it, and he assures me it's a great product."
 
For a new setup, with no history, and no investment in tooling, that's probably a mistake
3
 
> This has already been vetted by IT. It's what our tech support contractor uses.
 
I would consider two tools only, in a modern environment: git, and svn for pure version control.
if you want integration with issue tracking, then RTC, or GitLab

Issue tracking is a bonus, not a requirement.
The big thing here is we don't use any VCS at all right now.
 
Well, that is a serious problem
 
Yeah. It is. Which is why I initiated this.
 
I think I've seen enough summations for now
 
1:20 PM
@RubberDuck Personally, two things: 1. IBM is full of very large systems that do complicated things... we use RTC or ClearCase/ClearQuest for large projects, and git for the rest.
 
@skiwi Are you working with boolean circuits or something?
 
@rolfl I'm curious, why the choice for svn?
@SimonAndréForsberg It's part of the AI course, this is the probability part
I'm trying to study, all I see are summation signs though
 
second thing: 2. I would not work with PVCS in the modern world. (personally)
 
@rolfl Thanks for the insight. It's much appreciated.
I'm going to put my case together and push back.
 
but, note that I am in the situation where I can say things like that ("I'm not going to work with PVCS")
 
1:22 PM
@RubberDuck Do you have clear arguments why the antique system is worse than git?
 
What are they gonna do? Fire me? They're likely to do that anyway...
@skiwi File locking.
 
2 mins ago, by skiwi
@rolfl I'm curious, why the choice for svn?
 
One of the reason I asked for this is to ease simultaneous development.
 
@RubberDuck Oh god... case settled
2
 
A system that locks files and can't merge defeats one of the major pain points.
 
1:23 PM
@RubberDuck - note that is not strictly true ^^^^
 
Yes... I understand.
But, lets say I make an informed decision to change a class' interface.
 
A locking VCS has significant benefits (Clearcase is a locking system I have used before as well, and it works).
 
Benefits?
Can you elaborate please?
 
Merging is a complicated, bug-introducing process.
 
^^ that
 
1:25 PM
Eliminating merging is actually a good thing.
notifying people that someone else is working on your file before you start, is a good thing.
 
I'm voting to close this question as off-topic because optimization questions are more suited for CodeReview.SE. — cpburnz 1 min ago
 
YOu know that you will have to coordinate a change before you get far enough down the road that the merge is complicated
It all comes down to discipline, though.
whatever system you use.
in Git, it is good discipline to make small changes, often.
3
 
@rolfl That's true. "Whatever system you use"
Which is how we tend to make changes now.
Just the nature of what we do.
 
In other systems, it may make sense to lock out a chunk of the code, make large changes, test, commit, and then the next person can take a clean code base, and break it their own way
 
Hmmmm.... I've gotta go, but you've given me lots to think on. Can't thank you enough.
I'll let you know how it all pans out eventually.
 
1:28 PM
I would still go with the git process... ;-)
@skiwi - about SVN.... I like svn
 
If I can make it happen.... yeah. That's what I'm aiming for.
 
svn and git are two completely different ways of thinking about things.
 
meh... the one thing I absolutely hate about SVN is how hard a time it gives you with versioning and releases..
 
Compare that to CVS or anything else.....
 
Hmm, how do I explain that I like learning new things, but hate studying

Q: C# Chat - Part 2: Client

ArtOfCodeThis is the second part of a multi-part review. The first part, the server for this client, can be found here. I've been building a simple C# server-client chat-style app as a test of my C#. I've picked up code from a few tutorials, and extended what's there to come up with my own spec. In this...

What's the difference between SVN and git, @rolfl ?
 
@nhgrif They have different philosophies.
SVN is an incremental system, where each revision is a diff from the previous revision.
 
and git works snapshot based
 
git is a snapshot system, where each commit is a standalone pricess
Then, the implementations are different.
SVN has a centralized server which keeps the master implementation and contols access, merges, etc.
Git is distributed.
there is no master node in Git on a technical level. Each 'clone' has equal technical seniority.
the only concept of a master location for git code is the human imposed one of things like GitHub,
There is nothing technical about the github repository that makes it more special than other clones though
 
@rolfl meh. usually it's a --bare repo...
 
Well, if you want to compare the repo vs. the workspace, that's different.

I went looking for what @JeroenVannevel said to me to refresh my mind on Extension Methods. and then I realized I had already done it in my code! lol
 
You're welcome!
 
@JeroenVannevel are you going to run for SO moderator this year?
 
thanks. now I have an Extensions.cs file in my project. I think I should do that for all of my projects.
 
maybe the election page with nominations opening in 5 hours?
 
@Vogel612 I was thinking Code Review..... :(
 
3:03 PM
well that would be nice
and I do hope there's CR mod elections this year..
 
Not happy with the ones you have, huh?
 
but if none of our current (and awesome) mods step down, I think the results are pretty.. obvious ;)

@rolfl now that's what you said...
 
@rolfl not saying that, it just marks our true graduation, where we lose that pesky "Beta" label
 
There was a site recently..... hmmm

Q: Passing values to a partial view

gerdiI have button which I would like to use for update and create actions. Currently a create action is based on the URL parameter equalling 0 . If for instance, in a foreach loop item.id >= 1 the action then becomes an edit and maps the properties for that item. create : blog/0/new update : blog/3...

Q: HackerRank Angry Professor challenge

Calculus5000I've written an answer to HackerRank's Angry Professor problem. Please let me know if there's a quicker/better way of solving this as I think I wrote quite a bit of code for this problem (answer has to be in 1 class btw). Also, any improvements on my code in Java 8 are welcome too. Problem state...

Q: Congratulations! You're about to graduate... with a twist

Robert CartainoI wanted to pass on the announcement that this site has been cleared for graduation… congratulations! Graduation comes with it some perks — a listing in the footer of the other sites, you can start migrating content to and from this site, we have things like "community promotional ads" which are...

 
they still have the beta label, though ;)
 
I notice that too ;-)
 
I hadn't seen that one. is there a vote on whether or not we should bug the powers that be for the same "twist" ?
 
meh. Why would we? honestly I prefer to not be the guinea pig
 
I don't want to be any kind of pig. I like pigs, but I would find it hard to code without hands.

Yay I got it to run. Now I can go do idiotic stuff with it!
 
In this code am able to say return sum(filter(iseven, map(fib, range(1, n + 1)))) where sum and filter accept tuple = (1, 2, 3, 4) either.
I tried replacing range() with range_func() in this code but fib does not work, How do I make it work?
error is: TypeError: unsupported operand type(s) for -: 'tuple' and 'int'
please help me!!
 
Yeah, that sort of thing does not work so well on Code Review, or any other chat room.

Q: How can I limit pygame.draw.circle?

NHamesSo I have a draw area that I want to draw to and borders that I would not like to draw over. Currently, if the mouse positions (m_x & m_y) are within the circles radius of the border I have the program draw the circle and then redraw rectangles which cut off the part of the circle which crossed. ...

You cannot subtract an int from a tuple.
 
which is quite unsurprising...
 
3:24 PM
So, each element in tuple = (1, 2, 3, 4) and r = range(1, 5) are int?
 
@Vogel612: nah, I don't feel like going through that process again
 
and when you didn't make sense before, you actually managed to make less now..
@JeroenVannevel so bad?
 
where as each element in the sequence returned by range_func(1, 5) are not int?
 
Just really, really tedious
Answering 20 questions nobody will ever read. Lots of commenting

See the help center - note that your question would likely be closed as too opinionated on programmers.se as well. Your question is not a question as such, it is a discussion, blog, or article. It's an opinion piece requesting debate. There's nowhere on Stack Exchange where such poll questions are on topic, that I know of. — rolfl ♦ 46 secs ago

@Vogel612: thanks a lot for this response, which now enlightens me. I didn't realize this place's rules were so limitative. And I'm glad you pointed me to the Code Review Chat, since anyway I find the issue quite important to improve code. Thanks anew. — cFreed 45 secs ago
 
I see @cFreed ;-)
Welcome to the 2nd
 
There's really not much value in seeing more than one function in your screen, but functions shouldn't span multiple screens...
 
@Lyle'sMug - Running: stackoverflow.com/election/6 ?
 
4:10 PM
3 hours until nomination phase, btw.
 
Hi @rolfi, thanks for the welcome. As a newbee here, I'm a bit confused. Could you guide me on how to propose others to look at my question, recently refused (but I've seen it appears here, at the time it was posted... ???)
 
@rolfl I could use the practice for when CodeReview Elections come up.... single eyebrow raise
 
@Lyle'sMug can't enter anyways. There is a minimum requirement of 3k rep.
 
Malachi, South Dakota
2k 3 13 31
^^^ need 3K though
 
oh snap!
 
4:11 PM
@cFreed Your question is automatically posted here in chat by the feeds bot after it is asked.
 
@cFreed meh. the question is off-topic. making more people look at it will probably get you nothing but downvotes :(
 
Getting others to look at the question is ^^^ that.
How do I draw an analogy..... how about: the government creates the laws, and the courts enforce them?
 
@rolfi: I don't understand, since @Vogel612 lead me here, saying it was the right place for my issue, rather than in the Q&A part
 
it's more like the federal and state law.
@cFreed well chat is simply better for discussing things
 
It's better than hashing out a complicated thing in comments on a closed question.
 
4:14 PM
@rolfi: so not the right place here, too?
 
@cFreed - let me summarize.... you want to know whether it is better to have more compact code, than lots of white space?
Right?
 
@rolfi: quick response is 'yes'. But I'm interested to others opinions.

@rolfi: quick response is 'yes'. But I'm interested to others opinions.
Yeah, and that's the basic issue with your question on the main site.
Code Review is not the place to build, debate, and opinionate on whether lots of whiitespace is good, or bad.
Code Review is the place to say: this code does not use enough whitespace, or this code uses too much whitespace.
the difference is subtle.
 
How does one arrive at the latter two conclusions?
 
4:19 PM
@rolfi: the difference is subtle: sure!
 
@Rainbolt By applying what is already understood to be best practice, by applying common conventions that are used... and, @Rainbolt - by doing the opposite of Code Golf ;-)
Sure, there are differences, but they are suprisingly few, and, where there are uncertainties, the code review answers often don't recommend one way, or the other, but instead ignore that part completely.
code review answers that recommend the wrong practices, are downvoted by others too... so, bad answers (which most of the CR voters disagree with), go to the bottom.
The subtle difference then, is that bad practices are 'debated' in the voting on answers, not in direct opinion-seeking questions.
 
Maybe @JeroenVannevel or ~@nhgrif would like to run for SO mod?
 
Did that once. Wearing the tshirt they gave me now
 
Oh.
 
When my tshirt gets too small, I'll run for mod again
 
4:26 PM
Lol
 
So, to be short, what is already understood to be best practice comes from whet most of the CR voters agree or disagree?
 
To be shorter, most of us already agree on a best practice.
 
@cFreed In a sense, yes.
But, it is more practical than that
Consider your question.... what sort of answers will it get?
 
@rolfl What is more practical than what?
 
You guys think a link to the good subjective vs. bad subjective would help?
 
4:30 PM
@RubberDuck Why not?
 
Why not ;-)
 
@Hosch250 Hmm... it looks like a vicious circle: where do you consider best practices initially come from?
 
@cFreed Many of the best practices come from documentation.
Python, for example, has the PEP8 style guide, which is used by most Python programmers.
 
Robert Cartaino on September 29, 2010

Stack Exchange is about questions with objective, factual answers. We’ve been crystal clear about this for as long as I can remember, even back to the earliest, pre-beta days of Stack Overflow. It’s right there in the standard Stack Exchange FAQ:

What kind of questions should I not ask here?

Avoid asking questions that are subjective, argumentative, or require extended discussion. This is not a discussion board, this is a place for questions that can be answered!

Thus, questions that are not answerable — discussions, debates, opinions — should be closed as subjective. It seems simple enough: Fact good; opinion and discussion bad. But why? …

 
Others come from common sense - keep your methods to one thing, don't write a "god" method.
 
4:32 PM
And from years of experience, books written by the "greats".

Jon Skeet, for example.

@rolfl Thanks! :)
 
Or Martin Fowler, Steve McConnel, or Uncle Bob.

He is so good that he even gets people to pay to learn what not to do.
 
Heck, I'd toss Jeff Atwood and Spolsky in that mix too.
 
As English is not my native language I have great difficulty following: I give up ...
 
@cFreed Sorry, we can go slower.
 
Basically, 50 years of collective experience determines best practices.
 
and, what's more, is a question challenging what the best practices are, or should be, is just going to end up in a flame-war of bitter fighting.
 
4:36 PM
@Hosch250: thanks a lot, but Is is beyond that. Not only the speed, but the fact than I'm not familiar with the current language.
 
OK.

@rolfl K&R vs. TOTBS anyone?
No one wants to have that fight..... =;)-
 
It is always amusing when I take a day off school (Sunday), come back, and have 100+ discussion postings to read...
 
shhhh my first class in 12 years starts tomorrow. I don't want to think about it.
 
4:39 PM
@RubberDuck Real college class?
If I could just take one that interests me, I'd love it.
But 5 that don't interest me...
 
Auditing one online, but yes. I could pay to receive the credit if I really wanted to.
 
@cFreed I see your profile indicates you are in France. If you like I can try and help with your questions if you prefer French
 
OK.
I wasn't sure if it was a work class - my dad has to take N hours of training each year to keep his job.

Q: React mixin to declaratively get Bacon.js event steams
