• 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!

• 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?

• 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?)

• 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!

• 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.

• How to make an input element with 5px fill an entire <td>?

  - by Bytecode Ninja

  I have a text input inside a <td> that has a padding of 5px; When setting its width to 100% it comes out of the boundaries of the <td> for 10px. Is there a way to make it fill the entire <td> (i.e. in practice its width should become 100% - 10px) without using JavaScript? Thanks in advance

• Input field name starts with a number

  - by fire

  I have an input field whose name is an MD5 string e.g.: <input type="hidden" name="7815696ecbf1c96e6894b779456d330e" value="1"> Now I understand that having a number as the first letter in an input field name is generally bad practice, but are there any side-effects to this such as a certain browser won't send it in the POST request?

• Should I name the files in my solution all 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?

• Without width printing format in C

  - by yCalleecharan

  Hi, in C if I have a printf statement containing say "%.2f", it says that the precision is 2 digits after the decimal place. I haven't explicitly specify the width. I have two questions: Is this good programming practice?; Is without specifying the width means that the width of the field will get adjusted automatically when printing the number, irrespective of the number of digits it contains? Thanks a lot...

  I have a small app which has Users, Recipes, Ingredients and preparation models A user has many recipes, recipes belong to user and ingredients/preparation belongs to recipes.
