Questions about PHP and Java
I want to know how Java (JSP) on Tomcat compares to PHP on Apache in terms of performance. Two servers with the same hardware configurations, one running Tomcat/Java (JSP) the other Apache/PHP, both servers maxed out with how many connections they can handle at once. Would they be somewhat close or would one pull away from the other one...

Pulling HTML from a Webpage in Java
I want to pull the entire HTML source code file from a website in Java (or Python or PHP if it is easier in those languages to display). I wish only to view the HTML and scan through it with a few methods- not edit or manipulate it in any way, and I really wish that I do not write it to a new file unless there is no other way. Are there ...

Recommend Linux + Java books, resources for .NET developer
Hi, I want to learn Java and Linux. Java itself (as a language) is not a big deal for me as I know pretty well .NET and C# (so the paradigm is similar).

javabat question
Return an array that contains the exact same numbers as the given array, but rearranged so that all the zeros are grouped at the start of the array. The order of the non-zero numbers does not matter. So {1, 0, 0, 1} becomes {0 ,0, 1, 1}. You may modify and return the given array or make a new array. zeroFront({1, 0, 0, 1}) → {0, 0, 1, ...

Forgive me if this is an ignorant question, I'm not exactly an expert programmer just curious. Is it possible to read the working memory, say for an instance of a class, from inside a running program? I know you can do something like println(theInstance.getClass()); and it will give you the memory address of the instance (I'm assuming ...
enums as mini data tables
I tend to use enums to create mini data tables all over my code. I use this pattern often. Often enough that I thought I'd ask for others opinion. I'm just curious if I'm taking enums too far, or if I should be doing something else instead. A common example is an enum I'll use to drive the TableFormat(from glazed lists) in a JXTable(fro...

Hi, I have a requirement wherein I need a list of all the contacts that are edited/changed. As per the Android documentation, _SYNC_DIRTY will be set every time a contact is edited. But, there seems to be a bug in this, which makes this always set to 1 (no matter what), even is we explicitly set it to 0. So, I was wondering if I c...
Obscure your Ruby code?
I am in the middle of developing an enterprise application using RoR (first time for us to build an enterprise app on RoR instead of Java), and while we do not have that much problem of obscuring the source code, I was still wondering if this was possible.

Android: How do I know if Activity.onStop() is being called because the user is going back to Home?

The reason is because I need to know when it is appropriate to shut off music that is playing in my applicati...
