I've been using C/C++ and Python pretty seriously, but I now I see that a lot of new programming books use Java or C# as examples. I don't think I'll use Java or C# for the time being, but I guess I have to study one of the languages (or both of them) in order to read and understand the books. How similar Java and C#? If I learn Java...
So since Steve Jobs said Flash sucks and implied that HTML5 can do everything Flash can without the need for a Plugin, I keep hearing those exact words from a lot of People. I would really like to have a Chart somewhere (similar to http://en.wikipedia.org/wiki/Comparison_of_layout_engines_%28HTML5%29#Form_elements_and_attributes ) that ...
Recently I found an nice blog post presenting 2 approaches for tracking online users of a web site with the help of Redis. 1) Smart-keys and setting their expiration http://techno-weenie.net/2010/2/3/where-s-waldo-track-user-locations-with-node-js-and-redis 2) Set-s and intersects http://www.lukemelia.com/blog/archives/2010/01/17/redis...
When I compare two array values I see two strings that look the same. php doesn't agree. $array1 = array('address'=>'32 Winthrop Street','state'=>'NY'); $array2 = array('address'=>'32 Winthrop Street'); $results = array_diff_assoc($array1, $array2); var_dump($results) //echos ['address'] => string(18) "32 Winthrop Street" ['state']=...
Does a library or even standard API call exist that allows me to diff two strings and get the number of diff chars as an int? I wouldn't mind other features, just as long as I can get a more programmatic diff result (such as an int) instead of something that just outputs the entire human readable diff. ...

Command line or library "compare tables" utility for SQL server with comprehensive diff output to a file in .Net I can't find anything like that.

I have two small data frames, this_tx and last_tx. They are, in every way that I can tell, completely identical. this_tx == last_tx results in a frame of identical dimensions, all TRUE. this_tx %in% last_tx, two TRUEs. Inspected visually, clearly identical. But when I call identical(this_tx, last_tx) I get a FALSE. Hilariously, e...
Hi all, I can't seem to figure out what is wrong with my code. Maybe it would be simpler to just compare date and not time. Not sure how to do this either and I searched but couldn't find my exact problem. BTW, when I display the two dates in an alert, they show as exactly the same. My code: window.addEvent('domready', function() { va...
