• How enable GZIP compression for Spring HttpInvoker requests using Tomcat?

  - by Brian

  Hi, Wondering if anyone has set up GZIP compression for Spring HttpInvoker requests using Tomcat, and what steps are necessary? Also, any advice on whether it's actually worth it; is there much to be gained from trying to compress what are basically serialized Java objects, or do they not really reduce in size much? Thanks, Brian

• Register applications via Registry table rather than TLBs

  - by Mmarquee

  We register the capabilities of Delphi applications using TLB files. However, from reading MSDN documentation, "Installation package authors are strongly advised against using the TypeLib table. Instead, they should register type libraries by using the Registry table". Does anyone have any advice on how to do this in a 'Delphi' way for Windows 7?

• How can I distribute a bookmarklet in FBML?

  - by Eric

  I have a JavaScript bookmarklet that I'd like fans of a certain page to take. Unfortunately, the only way I've found of distributing it is giving them the raw JavaScript source, which is then problematic to add as a bookmark. Ideally, I'd use Drag this to the bookmarks bar But FBML filters out the JavaScript href. Any advice?

• Constructor overloading in Java - best practice

  - by errr

  There are a few topics similar to this, but I couldn't find one with a sufficient answer. I would like to know what is the best practice for constructor overloading in Java. I already have my own thoughts on the subject, but I'd like to hear more advice. I'm referring to both constructor overloading in a simple class and constructor overloading while inheriting an already overloaded class (meaning the base class has overloaded constructors). Thanks :)

  - by Thurein

  Hi, I was using the sys.ui.dataview, ado.net data services and a html page to provide an edit page.

• Large file uploads from web pages

  - by jerrygarciuh

  Hi folks, I code primarily in PHP and Perl. I have a client who is insisting on seeking video submissions (any encoding) from the public via one of their pages rather than letting YouTube do its job. Server in question is a virtual machine and I can adjust ini settings for max post, max upload size etc as needed. My initial thought is to use a Flash based uploader with PHP on the back end but I wondered if someone might have useful advice and experience on the subject? Peace JG

• How do I use try...catch to catch floating point errors?

  - by Peter Stewart

  I'm using c++ in visual studio express to generate random expression trees for use in a genetic algorithm type of program. Because they are random, the trees often generate: divide by zero, overflow, underflow as well as returning "inf" and other strings. I can write handlers for the strings, but the literature left me baffled about the others. If I understand it correctly, I have to set some flags first? Advice and/or a pointer to some literature would be appreciated.
