Linux RAM is composed of chunks of memory called pages. To free up pages of RAM, a “linux swap” can occur and a page of memory is copied from the RAM to preconfigured space on the hard disk. Linux swaps allow a system to harness more memory than was originally physically available.
However, swapping does have disadvantages. Because hard disks have a much slower memory than RAM, virtual private server performance may slow down considerably. Additionally, swap thrashing can begin to take place if the system gets swamped from too many files being swapped in and out. Continue reading

I always wanted to have personal home server which can host a web service with PHP, PERL, Python and MySQL, FTP or WebDAV services, Subversion service or stream multimedia.

Here is the step-by step description of how I setup my personal home server. Continue reading
