• Should I use more than one CSS sheet?

  - by Robert

  I am updating a website to add some mobile friendly pages. At the moment we have one big css page with everything in. My idea is to put all the mobile specific css into a separate file and then link both sheets. The mobile css will overide anything in the default css (bigger buttons etc). Im quite new to css, what is the best practice?

• Passing Activity Context to constructors to use internally - is this bad

  - by jax

  Is is bad practice to pass the Context to a constructor and save it as a private variable for internal use? The other option is to pass the Context as a parameter to methods that need it. Which is the better option? I have a feeling that passing to the constructor might result in memory leaks accidentally.

• Metaprogramming on web server

  - by bobobobo

  From time to time, I find myself writing server code that produces JavaScript code as the output result. I can point out why it is really bad: Inextricable tie between server code and client code. Can render client code un-reusable. But sometimes, it just seems to make sense. And isn't it kinda sorta interesting? I guess the question is, is writing server code that produces JavaScript code a really bad practice, or "does everyone do it"?

• Functional Programming Equivalent of Design Patterns Book?

  - by JasonFruit

  Is there a functional-programming equivalent to the Gang of Four Design Patterns book? That is, is there a book that explains and gives examples of how commonly-needed code structures are implemented functionally? I think seeing that would give me a better idea of how to go about using in practice the functional concepts whose theory I understand.

• Frequent Functions: How to Structure?

  - by cam

  How should one structure their frequently used non-important functions (conversions, etc) in C# since everything must be contained in an object? Usually I take all these functions and put them in a static Utility class. Is this a good practice? How do most developers do it?

  - by fig-gnuton

  With respect to OOP best practices, why do some people feel it's poor design if you call something a WhateverManager or WhateverController? Is this widely accepted as a best practice (to avoid this)? And what is the recommended alternative?

• Why is Private Accessor deprecated?

  - by user3918598

  It used to be the number one reason for us to choose MSTest from others that we could access and test private methods. Now that Private accessors are deprecated in Visual Studio 2012. Does anyone know why Microsoft make such decision? Is it because it's not a good practice to test private methods? Also, if I still need to unit test my private methods, how could I do that in VS 2012 and later versions?

• What's the fastest way to brush up on algorithms for a technical interview (on Monday)?

  - by nickl

  I have a technical interview on Monday and they were kind enough to give me a heads-up to brush up on my basic algorithms. It's been years since I looked at that kind of stuff and I'm pretty weak on it to begin with so I generally have a bad feeling about this. What's the best way to review the basics and get some practice in before Monday?

• Localized text in Java

  - by Eager Learner

  My requirement is to display localized text messages in a J2EE web application. I know J2EE provides very good support for this. My question is what is the practice followed to have the localized messages stored to be used by the application. If I want to display Japanese / Chinese kind of messages which are not like English like char sets how do we get that messages/text into the properties files or Database tables.

• Can you omit the parenthesis from attributes with no params?

  - by Joan Venge

  I noticed when I have Serializable instead of Serializable(), the code still compiles. Is there a rule for this that you can omit the parenthesis? Is it a good practice? It seems more readable to me unless I am missing something.

• Should I name my solution files in lowercase for SEO?

  - by Scott

  I read that an SEO best practice is to use lowercase urls. Should I name my asp.net webforms project files lowercase as well? Visual Studio doesn't name default documents in new projects all lowercase. I'm not sure it matters since browsing to http://www.mysite.com/mypage.aspx will still work even if your page is named MyPage.aspx. Can somebody enlighten me on this?

• Must declare function prototype in C?

  - by Mohit Deshpande

  I am kind of new to C (I have prior Java, C#, and some C++ experience). In C, is it necessary to declare a function prototype or can the code compile without it? Is it good programming practice to do so? Or does it just depend on the compiler? (I am running Ubuntu 9.10 and using the GNU C Compiler, or gcc, under the Code::Blocks IDE)

• Java: Making reference null after closing stream

  - by Hei

  Is it a good practice to set stream references to null after closing them? Would this release resources in any way? Example: BufferedReader input= new BufferedReader(new FileReader("myfile.txt")); // code input.close(); input = null; // possible more code

• Does java have a class that represents a timer?

  - by Eric

  I'd like a timer class that allows me to call: .start()   .getElapsedTime()   .stop()   .reset() Does Java have such a class, or do I need to use my own (which I've already written). From a best-practice point of view, I should use the Java class libraries classes if they exist, but I'm not sure whether this one does. Can anyone give me a link to the javadoc for this class, if it exists?

• validates_associated not honoring :if

  - by James Ferguson

  I'm totally blocked on this. See this pastie for sample code: http://pastie.org/990040 The first test will fail. The user model validates an associated address model, but is only supposed to do it if a flag is true. In practice it does it all the time. What is going on?

• Should the function or the caller be resonsible for input validation?

  - by haudenschilt

  I'm doing a security audit on a fairly large php application and was wondering where I should include my user-input validation. Should I validate the data, then send the clean data off to the back-end functions or should I rely on each function to do it's own validation? Or even both? Is there any standard or best-practice for this sort of thing? Currently the app does both inconsistently and I'll like to make things more consistent.

• I'm still learning OOP. Any tips on staying unbiased and pragmatic?

  - by marcdev

  I keep reading about defficiencies and issues with languages. Specifically, I'm learning PHP and Javascript, but I see it everywhere. This question arose while reading Javascript: The Good Parts and PHP Objects, Patterns and Practice. While understanding and avoiding easy pitfalls, is there a way I can learn the fundamentals of OOP and discover solid programming practices without overlooking important areas (or simply becoming jaded)? I'm sure I'll have plenty of opportunity to learn from mistakes!

• Why save output until the end?

  - by user509006

  Very quick question about programming practices here: I've always used echo() to output HTML code to the user as soon as it was generated, and used ob_start() at the same time to be able to output headers later in the code. Recently, I was made aware that this is bad programming practice and I should be saving HTML output until the end. Is there a reason for this? What is it, and why isn't output buffering a good alternative? Thanks!

• What are the standard practices for throwing JavasScript Exceptions?

  - by T.R.

  w3schools says that exceptions can be strings, integers, booleans, or objects, but the example given doesn't strike me as good practice, since exception type checking is done through string comparison. Is this the preferred method of exception handling in JavaScript? Are there built-in exception types (like NullPointerException)? (if so, what are they, what kind of inheritance do they use, and are they preferred over other options?)
