  - by A sw A

  Write a JavaScript that accepts a number from the user using the “prompt” function. Then it draws a table in the HTML document that has the user specified number of rows and columns. In each table data, it displays the result of the math operation (row raised to the power of column). For example, if the user enters the number 3, the JavaScript should draw the following table: 1 1 1 2 4 8 3 9 27

• boolean VB expression returning false for integer 1

  - by Bill

  This is probably a really basic (no pun intended) question, but I can't seem to find an answer anywhere. Why does the result of func1 return False and func2 returns True? On every other test I have done, integer 1 is converted to boolean true and 0 to false. Works ok if I just set rtnValue to 1 or 0. Public Function func1() As Boolean Dim rtnValue As Integer = 0 Return rtnValue = 1 End Function Public Function func2() As Boolean Dim rtnValue As Integer = 0 Return rtnValue = 0 End Function

• jQuery plugins: How can I stop divs from overlapping?

  - by anir

  I'm using Masonry and Embedly plugin to display embedded content, I've put together an example in jsfiddle.net/anir/pBtbb/3/ It appears the Masonry plugin loads first and it causes the overlapping problem (they only show correctly when you resize the result window) I've read that I could use callback functions or retrigger Masonry once embedly has finished rendering content, but I don't know how to do it.

• Java threads for the beginner

  - by Boba

  I've been trying to explain Java threading to a colleague who has never been exposed to multi-threaded applications, but apparently I'm not a very good teacher. Can anyone recommend a good online or offline resource that can explain threading in a simple, step-by-step manner? I know it's a complex topic, but surely there exists an article, book, or other explanation that can result in an "Aha! I get it, finally!" moment.
