Do you need to filter input fields in your form to prevent users from filling them in incorrectly. Use this simple Javascript function to filter user input and remove invalid characters depending on the filter type. I have used this function in a few projects and does not require jQuery. You can easily add additional filter types to the function. The below example can filter integers and floats.

You can use this function by with Javascript events or directly in your HTML.

You can also change the event to filter input other events like onchange or onblur.

An application with a vulnerability can be used by an attacker to dump the contents of a database, delete the database contents, insert HTML code to perform Cross-site scripting (XSS) attack, and much more.

Are you have problems with automated SPAM bots submitting to your PHP form? This can easily be fixed by adding a CAPTCHA to your form. CAPTCHA stands for: Completely Automated Public Turing test to tell Computers and Humans Apart. The main purpose of a CAPTCHA is to distinguish human from a computer. A code or image is presented in a way that only a human would be able to understand, so say good bye to automated SPAM!

If your system abruptly loses power, or if a RAID card is beginning to fail, you might see an ominous message like this within your logs:

EXT3-fs error (device hda3) in start_transaction: Journal has aborted

Basically, the system is telling you that it’s detected a filesystem/journal mismatch, and it can’t utilize the journal any longer. When this situation pops up, the filesystem gets mounted read-only almost immediately. To fix the situation, you can remount the partition as ext2 (if it isn’t your active root partition), or you can commence the repair operations.

Very useful search and replace command for the linux command line. This command is made up of a find command to find the files that you want and a perl command to do the text replacement.

The first part “find . -type f -name “*.html” -print” finds all of the files starting at the current directory that end with .html. The “-type f” makes sure that only files are found and not directories. The string that comes after the -name parameter is the filename to find. The -print parameter just prints the
the relative path to the found file.

The -exec parameter is used to execute a command with the found file. Everything after the -exec is executed until it reaches “;”.
