• When is it appropriate to use error codes?

  - by Jim Hurne

  In languages that support exception objects (Java, C#), when is it appropriate to use error codes? Is the use of error codes ever appropriate in typical enterprise applications? Many well-known software systems employ error codes (and a corresponding error code reference). Some examples include operating systems (Windows), databases (Oracle, DB2), and middle-ware products (WebLogic, WebSphere). What benefits do error codes provide? What are the disadvantages to using error codes?

• Does the VB6 IDE run on Windows 7 64-bit

  - by jasonk

  We're approaching a point of replacing several of our developer PCs and would like to move up to 64-Bit to maximize the hardware/life of the PCs but we also need to support several legacy VB6 applications. That said, does the VB6 IDE run on Windows 7 64-bit? Microsoft says it's not supported, but that doesn't necessarily mean it doesn't work. Does it work? Are there any pitfalls/workarounds needed to get it running?

• GWT: library for encoding/decoding arbitrary data in URL fragments

  - by Caffeine Coma

  Ajax applications, and GWT in particular, use the URL fragment (e.g. http://example.com/myapp#fragment) to maintain application state on the client without reloading the page. Is there a GWT library that facilitates the encoding and decoding of arbitrary parameters into the URL fragment? I'm looking for something analogous to the Servlet API's getParameter() method, but for client-side URL parameters.

• Customizing the look of S3 expiring urls

  - by Gregoriy

  Creating expiring links for Amazon S3 buckets, could I somehow change the name of AWSAccessKeyId to something else (to custom it, to speak so) so that not to disclose the use of Amazon in my web applications? For now, it looks like so: http://video.mysite.com/T154456.flv?AWSAccessKeyId=1ESOMESPECIALIDJJAKJ6RA82&Expires=1241372284&Signature=ddfr%2BlkoSEPAL%2BGbMwlMzj6q%2BCY%3D Or, in order to not open another question, what are other (tricky?) ways to expire S3 links without the use of proxy?

• How to synchronize HTML5 local/webStorage and server-side storage?

  - by thSoft

  I'm currently seeking solutions for transparently and automatically synchronizing and replicating across the client-side HTML5 localStorage or web storage and (maybe multiple) server-side storage(s) (the only requirement here that it should be simple and affordable to install on a regular hosting service). So do you have any experience with such libraries/technologies that offer data storage which automate the client-server storage synchronization and allow data to be available either offline or online or both? I think this is a fairly common scenario of web applications supporting offline mode...
