performance - Detect system load with emphasis on "swap thrashing" in Linux -

September 15, 2012

I created a Bash prompt, when the working directory is a Git repository, displays the name of the current repository. In addition, it includes ongoing work and time spent on it (from a HomeBride timekeeping tool). This, of course, means that just the prompt means to run two processes.

There is a lack of that if the system is cracking for any reason, then it is necessary to save Killall system, such as git Binary is too much ask the system in such a situation.

So, now the prompt is disabled by default, and is only enabled on demand, but it is not as simple as it would be good to detect load in .bashrc And if the system is running fine (with acceptable disk latency only) will enable the prompt.

  In such situations, the CPU is quite cheap, only discs are expensive. So, I want to find a way that finds out the beating on the basis of external utilities. 
  Indication:  can be useful in   such as  / proc / loadavg  will solve my problem if this is the CPU which causes obstacles Is formed, not the disc

  
   vmstat  can help you if you do not want to use it , Then 
   / proc / meminfo 
  / proc / stat 
  / proc / pid / state

Short URL Outbound Link Tracking in PHP and MySQL -



    I have a site that reduces the link based on this topic. I decided that it would be great if users click on a small URL, like HootSuite users can track their links. I currently have a database in which the short URL is placed with the actual URL and this click count will ideally update the click count column when that small URL is accessed by an external user.   In short, I am looking for a PHP / MySQL solution so that many small URLs can be clicked. . Any additional information gathered from the clicks will also be highly appreciated.      I'm assuming you followed the PHP version of your tutorial. If so, look at listing for service.php under "service of small URL". In section round line 11 where it determines the position of 301, you can redirect with the database update. Something like    $ query = mysql_query ("update`" $ database. "` .```_AL_DIRED`Set count = count + 1 where` small '=' ".mysql_escape_string ($ short) , $ Db); $ Line = ...

php - How do I set up pagination for an image gallery with image
thumbnails? -



    I have two tables:    gallery id | Name | Details Image ID | Title | Caption | Gallery ID    By listing all thumbnails or paging through thumbnails I got the code to create a simple image gallery. However, what I need to do is here something like gallery here Only completes without javascript and ajax:     I want a selection number to show below the main image as soon as the user clicks the thumbnail, the page Selected new Highlight the image and the series of thumbnails on boto goes forward one by one if its not the last image.   How do I do this? Do I need a quick and dirty way to do this? I am using php and mysql for the database here - just need code to show 'paged' images below the main image. I know how to install everything i.e. Thumbnail size etc ...      I do not know the number of your rows in MySQL for T-SQL As there is a ROWNUMBER () function, but to do this, it is a smart way to sequential numbering of your images in the database. From there, you ask something ...
