Finding process memory usage on Linux

Recently I came up with a script to quickly print the memory utilization of specific processes on Linux. It’s very simple, but proven to be very handy while I was moving and tuning my VPSs. It quickly showed me that Apache was taking pretty much all my memory and motivated the migration to nginx.

It’s currently set to get the Resident Set Size (RSS), but you can easily change it to use Virtual Memory (VSZ). Just change ‘rss’ to ‘vsz’ in the ps commands. Also, you can add more processes to the script. Just add a new line and change the process name.

WordPress supports RSS Cloud now!

If you still don’t know, WordPress adopted RSS Cloud ( for all its blogs today!

RSS, short for Really Simple Syndication, helps you stream all of your news and blog sources into an easy-to-manage RSS reader such as Google Reader. Millions of people use RSS to keep up with Mashable, The New York Times, and even LOLcats.
However, it does have its limitations. The big one is speed. It can take minutes to hours for a blog post to reach the reader through RSS. This has been a big reason why more and more people are turning to real-time services like Twitter and FriendFeed for their news. In the real-time web, delayed news and information just isn’t good enough.
Now WordPress has done something big that eliminates that RSS delay problem and brings’s 7.5 million blogs into real-time, along with any other self-hosted WordPress blog. It has implemented RSSCloud, an RSS element that makes instant syndication of blog posts possible. However, it does have a few obstacles to overcome before your RSS is just like Twitter.

Obviously I already updated the blog to support it too. Now everyone with a compatible RSS Reader can have instant syndication!
