• Microsoft DBMS on-the-fly aggregation

  - by ILya

  Some time ago i was reading an article about new MS DBMS technology. It's some kind of OLAP but on the fly. This technology can bind to data flows and then provide a real time aggregation. So the question is "what is it's name?". I need such a technology now but can't remember it's name... Or maybe there are some similar technologies?

• Flex - Custom Component - Percentage Width/Height

  - by Hamish

  I am trying to create a Custom Flex Component using the Flex Component framework: http://www.adobe.com/livedocs/flex/3/html/help.html?content=ascomponents_advanced_3.html. All good components allow you to define their dimensions using percentage values using: MXML: TextInput width="100%" or Actionscript at runtime: textinp.percentWidth = 100; My question is how do you implement percentage width/height in the measure() method of your custom component? More specifically, these percentages are converted to pixels values at some stage, how is this done?

• A taxonomy of web frameworks?

  - by Rob

  There seem to be several different categories of web frameworks, e.g. MVC, component based, event-driven, action-based, etc. I can't find a comprehensive list of categories and definitions anywhere. (I dare not ask for examples as well.) Is there a general taxonomy of web application frameworks somewhere, or is this too fuzzy a question to allow for definitive answers?

• Matlab - binary vector with high concentration of 1s (or 0s)

  - by JohnIdol

  What's the best way to generate a number X of random binary vectors of size N with concentration of 1s (or, simmetrically, of 0s) that spans from very low to very high? Using randint or unidrnd (as in this question) will generate binary vectors with uniform distributions, which is not what I need in this case. Any help appreciated!

The key is: HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/CurrentVersion/Explorer/Advanced/Folder/Hidden/SHOWALL Trying to do this from C#, but the question is not language-specific.

• Why must we "change temporary credentials for token credentials" in OAuth?

  - by PK

  Can't the server just "upgrade" the temporary credentials to token credentials and retain the same key and secret? The client can then start doing authenticated calls right away after the recieving the callback from the server stating that the temporary credentials has been "upgraded". Of cause if the temporary credentials have not be upgrade (i.e. client doesn't wait for callback) the authenticated call fails. So the question is why make an extra call to the server after the callback to "exchange" temporary credentials for token credentials?
