•  MySQL: Overview of the ALTER TABLE Statement 17 maj 2012, 18:11

  In the past, we showed you just how easy it is to create a table in MySQL. Tables are an essential building block in MySQL that help to form and sculpt the overall structure of your database. We noted that once you have created a database, the time comes when you need to determine what type of structure you want it to have. In other words, a few questions come to mind, such as what specific tables do you want your database to have? What type of information do you want each of these tables to store? Also, what columns do you want each of your tables to have? These are just some questions ...

•  App Promo Survey Displays Developer Struggles 10 maj 2012, 17:04

  To come up with the data for its First Annual Developer Survey, App Promo collected opinions from over 100 qualified app developer participants between April 4 and April 23, 2012. While the survey provided plenty of interesting feedback from its participants, perhaps its most eye opening finding was the fact that 59 percent of developers said their most successful app failed to generate the revenue necessary to break even with their investment into the project. Add to that the 80 percent who said that they could not support a standalone business with the revenue generated from their top app,...

  

•  Lists and Arguments in Perl 08 maj 2012, 17:00

  Lists Are One Dimensional Recall that all lists and all arrays are one dimensional. If we have this list: (@a, @b) it becomes a one-dimensional list containing the contents of @a followed by the contents of @b . This is an important rule when it comes to passing arrays into functions, since they will be passed in as a one-dimensional list. This is illustrated in the following example: #!/usr/bin/perl -w # passarrays.pl use strict; my(@nums1, @nums2); @nums1 = (2, 4, 6); @nums2 = (8, 10, 12); process_arrays(@nums1, @nums2); sub process_arrays This program creates two 3-element ar...

  

•  Variables and Arguments in Perl 02 maj 2012, 17:30

  Lexical Variables (aka Local Variables) The range of effect that a variable has is called its scope, and lexical variables declared with my() are said to have lexical scope. This is also known as local scope. That is, they exist from the point where they're declared until the end of the enclosing block. The name lexical comes from the fact that they're confined to a well-defined chunk of text. my $x; $x = 30; print $x; # This $x is, and always has been, 30. Great. We can now use variables in our subroutines in the knowledge that we're not going to upset any behavior outside them. Let...
