• mysql innodb:innodb_flush_method

  - by Daniel

  in the following link http://dev.mysql.com/doc/refman/5.1/en/innodb-parameters.html#sysvar_innodb_flush_method it says:Different values of this variable can have a marked effect on InnoDB performance. For example, on some systems where InnoDB data and log files are located on a SAN, it has been found that setting innodb_flush_method to O_DIRECT can degrade performance of simple SELECT statements by a factor of three. Why O_DIRECT could slow down the select statement?

• SQL Alter Table to Add a Column, does it do anything "scary"?

  - by Pselus

  I need to add a column to an existing table in my live sql database. I know how to use the ALTER command, but what I want to know is the effect this has on the table. For example,, if using SQL Management Studio, it claims that adding a column will "drop and recreate" the table. Will the ALTER table command do that as well? This table is CONSTANTLY accessed and VERY important so I want to make VERY sure of this before going forward.

• AngularJS directives with async content

  - by SirDavik

  I'm generating a dynamic number of Google Charts tables after receiving the content through an ajax request and I wanted to apply an accordion effect on them. I wanted to know if I could do that with directives (since if I just code render the angular tags they won't get interpreted). I don't need a code example, just a short answer to see if I should learn directives or if I should do it in a different way (I was thinking routeParams). Thanks!

• How could I generate instances of an object randomly at the top of the screen and make them "fall"?

  - by Custard

  I am making a game in Flash CS4 (actionscript 3) and I would like to be able to make "copies" of an instance that would randomly appear at the top of the screen and fall. For example, multiple objects(that are the same one) are falling from the top of the screen continuously, starting at random X positions. (i think this would be considered Real-Time effect). P.S., please tell me if the information is insufficient for an answer, I couldn't think of much more to add to it. Thanks for your time and answers, -Custard

  GNU xargs has option '-x'. The man page says: -x Exit if the size (see the -s option) is exceeded. But xargs seems to not care if -x is set or not.
