• What does it mean that "File Stats" are slow on Windows as the reason Ruby is slow?

  - by aronchick

  In another question I asked (why is Rake test so slow), part of the response was that: The reason is that file stat's in windows are dreadfully slow, and, since Ruby is written on Linux (and optimized for Linux), there hasn't been much work to make it faster. Can someone explain this further?

• JSP/Servlet CRUD form with special input field based on join table relationship

  - by user1701467

  There's database with a bunch of tables that are joined with join tables. E.g. Members and Division are joined with MembersDivisions table. JSP/Servlet login functionality has been developed, but now the CRUD functionality needs to be implemented and I was unable to find any tutorials about it, especially involving the join table(when creating new division you can add members to it, or add more to the existing one). Maybe someone could, theoretically, explain how to do the Division part of the CRUD web form?

• Implementing a recently used or favorites dropdown in JComboBox

I found the following (which looks exactly like what I want, but the source code is nowhere near complete): http://java.sys-con.com/node/36658 Any suggestions? I need to keep this relatively light, so I'd prefer to not use a component that's part of a monolithic widget library, and open source is preferred.

• Why use NoSQL over Materialized Views?

  - by JustinT

  There has been a lot of talk recently about NoSQL. The #1 reason why I hear people use NoSQL is because they start to de-normalize their DBMS data so much so, to increase performance, that they end up with just one table with all of their data within that single table. With Materialized Views however, you can keep your data normalized, yet have it stored as a single table view for the same reasons why you'd use NoSQL. As such, why would someone use NoSQL over Materialized Views?

• Simple caching mechanism in ASP.NET

  - by DotnetDude

  I had asked a question on how to implement real time updates in ASP.NET and received a very explanatory and a helpful answer from "jdk" at: http://stackoverflow.com/questions/2347771/how-to-implement-real-time-updates-in-asp-net I understand that memcached or .net caching application block can be used as the caching layer.
