• Testing your code before releasing to QA

  - by user279521

  I have heard developers say that people who write code should not be the ones testing it. I am looking for peoples experience in this situation. Many times I have done my share of development, then released to the QA dept and had the code sent back to me becuase some aspect of the application was broken due to my coding, regardless of how much I had tested it prior to QA release. Does anyone on this board have a process to follow, that enables them to throughly test their code before releasing to QA?

• Gratuitous use of System.Runtime.Serialization attributes?

  - by rasx

  Is there any cost/drawback (apart from typing too much) to adorning a class with System.Runtime.Serialization attributes (like [DataContract]) such that it can be used locally as a direct reference to a desktop Client project or as a type for a WCF service? The goal here is to write a data-tier class that can be used in both rich client (WPF) and Web scenarios. My data classes will be in a project that is separate from Client and WCF (*.svc code-behind) code. Is this a valid attempt to reuse code?

• Are vb.net eventArgs maintained at a "system" level?

  - by GregH

  I have a custom developed control I am using that somebody else wrote. For some reason, when the control was written, they did not write an event handler for the "mouseDown" event so when I mouseDown on the control, no event is fired. What I am basically trying to do is capture which mouse button (left or right) is pressed when the control is clicked on. Is there any sort of system level objects that maintain system state (including which mouse buttons are currently being pressed regardless of the control being clicked upon?)

• Most hazardous performance bottleneck misconceptions

  - by David Murdoch

  The guys who wrote Bespin (cloud-based canvas-based code editor [and more]) recently spoke about how they re-factored and optimize a portion of the Bespin code because of a misconception that JavaScript was slow. It turned out that when all was said and done, their optimization produced no significant improvements. I'm sure many of us go out of our way to write "optimized" code based on misconceptions similar to that of the Bespin team. What are some common performance bottleneck misconceptions developers commonly subscribe to?

• Mathematica equivalent of Ruby's inject

  - by Ben Alpert

  Is there a Mathematica function like inject in Ruby? For example, if I want the product of the elements in a list, in Ruby I can write: list.inject(1) { |prod,el| prod * el } I found I can just use Product in Mathematica: Apply[Product, list] However, this isn't general enough for me (like, if I don't just want the product or sum of the numbers). What's the closest equivalent to inject?

• FirePHP not returning ajax request queries, yet returns normal page load queries

  - by user312867

  I am using firePHP(Zend profiler) on on FF 3.6.3(firephp addon installed) and it returns queries, when I do a normal page load. Ajax requests, however, are not returning the proper queries. I am using Prototype 1.6.0.2 for ajax requests. Is there something I am missing? Most of the write-ups seem to imply that this should work by default.

• what does process geometry mean?

  - by wenlujon

  from ARM DDI 01001, there is a term: process geometry, does it mean the chip size? Caches and write buffers to improve average system performance are now commonplace in ARM® memory systems. Core clock rates have increased at a faster rate than memory access times over recent years. This factor, and smaller process geometries, the economics of on-chip memory, and system power constraints have encouraged the use of caches to meet growing system demands. thanks.
