Think ahead of time. Do not create / register a cPanel account using your main domain (Ex: nobigdeal.com). Instead, register a cPanel account using something like cpanel.nobigdeal.com and make sure, this account is allowed to create addon domains.

Tired of remembering passwords? Here's a bash script to automate SSH login for you. Create an empty file sshlogin.

#!/usr/bin/expect -f spawn ssh -p 22 [email protected] expect "assword:" send "YourPasswordHere\r" interact

It works on Linux. Don't forget to add execution permissions. Run it like:

$ ./sshlogin

Traditionally, when talking about the difference about scripting versus programming, scripts are interpreted and programs are compiled. A language can be executed in different ways - interpreted or compiled (to bytecode or machine code). This does not make a language one or another.

In some eyes, the way you use a language makes it a scripting language (for example, game developers who develop mainly in C++ will script the objects in Lua). Again, the lines are blurred - a language can be used for a programming by one person and the same language can be used for scripting language by another.

This is from the wikipedia article about scripting languages:

A scripting language, script language or extension language is a programming language that allows control of one or more software applications. "Scripts" are distinct from the core code of the application, as they are usually written in a different language and are often created or at least modified by the end-user. Scripts are often interpreted from source code or bytecode, whereas the applications they control are traditionally compiled to native machine code. Scripting languages are nearly always embedded in the applications they control.

You will notice the use of "usually", "often", "traditionally" and "nearly always" - these all tell you that there is no set of distinct attributes that make a specific language a "scripting language".

Sharing a reply from a system admin who helped me optimizing MySQL for high server load.

Hello,

I've expanded your myism key buffer size which should allow more mysql caching. You are having a lot of traffic to mysql. Lots of reads and writes to the same database table. With that amount it's going to cause a lot of CPU i/o wait. This is the CPU waiting on mysql to process and send it's response. Your server might just have it showing a lot of load on it. The rule of thumb is 1 load per core but a lot of servers will have a lot of traffic to the server where the server can handle it just fine it just looks like it's a very high load.

Innodb has the table stored in memory and allows for tables to be locked by row and not by table themselves so it should have helped. It did a little but you just have a lot of traffic.

Of your traffic i have noticed that Microsoft and other search engines are hitting your site hard right now.

Solutions

Keep form processing and email scripts on a low cost shared server which you can easily migrate

Alway create a cPanel email address and include in email recepients

PHP Interview Questions

A list of bullets I put in front while taking PHP Interviews. This list isn't all question and answers but points which can be discussed with the candidate to assess his/her level of expertise.
