Advantages of std::for_each over for loop
- by Rahul G
Are there any advantages of std::for_eachover for loop? To me, std::for_each only seems to hinder the readability of code. Why do then some coding standards recommend its use?

What are common mistakes PHP programmers make when developing in Python?

Perhaps by compiling a list of common errors or coding style differences PHP coders make when first starting out with Python, we can help to avoid headaches later on. (Or at least I can :).Read the article

Git: Run through a filter before commiting/pushing?
- by martiert
Hi. Is there a way to run the changed files through a filter before doing the commit? I wish to make sure the files follows the coding standards for the project. I would also like to compile and run some test before the commit/push actually takes place, so I know everything in the repo actually works.Read the article

is there any programming language that can bring together edit and compile / run ???
- by Aff
When I code, I always write little pieces of unit, and compile it often. This helps me to make sure that everything run correctly, but it's very time consumed. is there any programming language that can support us to do coding and running at the same time side by side ? i mean as soon as a key press leads to valid code, the effect of the edit is…Read the article

ruby/ruby on rails memory leak detection
- by Josh Moore
I wrote a small web app using ruby on rails, its main purpose is to upload, store, and display results from xml(files can be up to several MB) files. After running for about 2 months I noticed that the mongrel process was using about 4GB of memory. I did some research on debugging ruby memory leaks and could not find much. So I have two…Read the article

Parse HTML file to grab all ID and Classes for a CSS file
- by iamfriendly
Hey all, A short while ago, I'm fairly certain I came across an application (or perhaps a plugin for Coda - the IDE I use) which quickly parses a html document and then spits out all of the elements with IDs and Classes for me to use in a CSS file. Having fully 'got into' zen coding - using the wonderful TEA plugin for Coda, I'm now hot…Read the article

Is there a code style enforcer?
- by Petruza
I'm working with websites written in PHP, along with many other programmers, and sometimes I have to deal with really awful code. Indentation totally messed up, curly braces in the wrong places, terrible whitespace use, it really hurts my eyes and actually makes my work harder and take longer. Is there a tool where you can specify your…Read the article

How does NSValue do its magic?
- by Paperflyer
I have an MVC application. The model has a property that is a struct NSSize. It is writable like this: - (void)setSize:(NSSize)aSize; The view sets this NSSize using key-value-coding. However, you can not key-value-code a struct, so I wrapped it in an NSValue-object like this: [theView setValue:[NSValue valueWithSize:mySize] …Read the article

Can Eclipse parse and use emacs-style meta information in source code?
- by ataylor
In emacs, it is possible to start a file off with a line this: /* -*- mode: java; c-basic-offset: 4; indent-tabs-mode: nil -*- */ This instructs emacs to use 4 spaces for indentation. I like the idea of storing this coding style meta-information directly and explicitly in the source code. Are there any options for doing this in…Read the article

Boolean Code Clarity - which style to use? [closed]
- by Anonymous
I was wondering what style others' use when writing conditional statements that include boolean types. Currently I'm caught between using two styles. bool foo; if (foo == true) if (foo) if (foo == false) if (!foo) Obviously the first set is a bit more obvious. However, when combining conditions it could get a bit clunky. if…Read the article

Textmate tab and de-tab selected block
- by Derek Organ
Recently switched to Textmate on Mac for coding. On PC when ever I want to tab in or out a block of code I just highlight and press tab or shift+tab to move it in our out. It's very useful when you are adding an extra loop or conditional statement to a block of code to keep everything tidy and neatly indented. On Textmate…Read the article

What should I read to improve my C++ style
- by Victor Ronin
I was developing for quite long time already on C/C++ (mostly C, which makes style poorer). So, I know how to use it. However, quite often I stuck with style decisions like: - should I return error code here, throw exceptions, return error through a parameter - should I have all this stuff in constructor or should I create…Read the article

code-style: Is inline initialization of JS objects ok?
- by michael
I often find myself using inline initialization (see example below), especially in a switch statement when I don't know which case loop will hit. I find it easier to read than if statements. But is this good practice or will it incur side-effects or a performance hit? for (var i in array) { var o = o ? o : {}; //…Read the article

Forced naming of parameters in python

In python you may have a function definition: def info(object, spacing=10, collapse=1) which could be called in any of the following ways: info(odbchelper) info(odbchelper, 12) info(odbchelper, collapse=0) info(spacing=15, object=odbchelper) thanks to python's…Read the article

Best way to check for nullable bool in a condition expression (if ...)

I was wondering what was the most clean and understandable syntax for doing condition checks on nullable bools. Is the following good or bad coding style? Is there a way to express the condition better/more cleanly? bool? nullableBool = true; if (nullableBool ?? false) { ... } else { ... } especially the…Read the article

Should every class have its own namespace?
- by thehouse
Something that has been troubling me for a while: The current wisdom is that types should be kept in a namespace that only contains functions which are part of the type's non-member interface (see C++ Coding Standards Sutter and Alexandrescu or here) to prevent ADL pulling in unrelated definitions. Does…Read the article

Why do so many mathematicians format code so poorly? [closed]

I have done a fair amount of programming together with mathematicians. Now I am even teaching some high school kids coming from a mathematics background how to program. Most of these people format their code so hideously it's hard to believe. I've even worked with and taught mathematicians who will fight…Read the article

I was speaking to an experienced lecturer recently who told me he could usually tell which programming language a student had learnt to program in by looking at their coding style (more specifically, when programming in other languages to the one which they were most comfortable with).

C# new class with only single property : derive from base or encapsulate into new ?

int vs const int&
- by Valdo
I've noticed that I usually use constant references as return values or arguments. I think the reason is that it works almost the same as using non-reference in the code. But it definitely takes more space and function declarations become longer. I'm OK with such code but I think some people my…Read the article

including .h files.

Suppose I have two .h files: A.h and B.h. Moreover, A.h includes B.h itself: B.h - declares class B. class B { ... }; A.h - declares class A, which uses class B. #include B.h class A { void SomeFunction(const B& b); }; Now, I have some .cpp file, that uses both A and B classes…Read the article
