问题 I want to calculate how much CPU time my function takes to execute in Java. Currently I am doing as below. long startTime = System.currentTimeMillis(); myfunction(); long endTime = System.currentTimeMillis(); long searchTime = endTime - startTime; But I found out that for the same I/P I get different time depending on system load.

阅读更多关于 How to run batch script without using *.bat extension

Is there any method in Windows through which we can execute a batch script without *.bat extension? This is an interesting topic to me! I want to do some observations about it. The important point first: A Batch file is a file with .BAT or .CMD extension. Period.

阅读更多关于 Does php execution stop after a user leaves the page?

问题 I want to run a relatively time consuming script based on some form input, but I\'d rather not resort to cron, so I\'m wondering if a php page requested through ajax will continue to execute until completion or if it will halt if the user leaves the page. It doesn\'t actually output to the browser until a json_encode at the end of the file, so would everything before that still execute? 回答1: It depends. From http://us3.php.net/manual/en/features.connection-handling.php: When a PHP script is

Eclipse: export running configuration

阅读更多关于 Eclipse: export running configuration

问题 I wrote a complex Java application with eclipse that uses many .jar libraries included into project folder. Is there a quick way to export a running configuration of the application that allows me to run it from shell (I don\'t actually need to move it around machines, so no jar export or similar things).
