• Translate Linq Expression to any existing Query structure?

  - by fredlegrain

  I have some kind of "data engine" between multiple "data consumer" processes and multiple "data storage" sources. I'd like to provide Linq capabilities to the "data consumer" and forward the query to the "data storage". The forwarded query should be some structured query (like, let's say, NHibernate Criteria). Is there any existing structured query library that could allow me to "just" translate a Linq Expression to such a structured query?

• What happens to orphaned/killed async AJAX WebMethod or PageMethod calls?

  - by Armchair Bronco

  What happens behind the scenes if I make an AJAX PageMethod or WebMethod call from, say, "Default.aspx" and then I quickly navigate away to a different page, say, "Settings.aspx" before the initial PageMethod has returned? What kind of housekeeping, if any, takes place on either the browser or the ASP.NET back end? In other words, where do abandoned AJAX PageMethod calls go to die...and what is their funeral like?

  - by Farinha

  I was amazed to find out that apparently Eclipse doesn't come with a decent HTML editor by default (it opened my .html file in some kind of browser view and apparently tried to render it).

• The internal implementation of R's dataset

  - by Yin Zhu

  I am trying to build a data processing program. Currently I use a double matrix to represent the data table, each row is an instance, each column represents a feature. I also have an extra vector as the target value for each instance, it is of double type for regression, it is of integer for classification. I want to make it more general. I am wondering how what kind of structure R uses to store a dataset, i.e. the internal implementation in R.

• How faster is using an internal IP address instead of an external one?

  - by user349603

Thank you in advance for your insight.
