$Parallels

You have an interface now to configure your Virtual Machine settings, including memory and disk very easily.

Some observations.
The install process is more true Windows XP, format drive, reboot, all options etc. With Win4LinPro a lot of this was shielded (which was impressive in itself).

The Parallels VM runs in it’s on window, but you get locked in when you mouse click to focus. Using Ctrl-Alt, your focus is returned to your host environment.

Parallels is clearly a more rounded product, providing many more host environments. The interface provides a lot more virtual feel. You have Disk/CD/Network/Sound icons embedded in the window

In this install sound also worked by default, it did not in Win4LinPro. The playing of audio was actually a good indicator during the Windows activation process (which wasn’t in Win4LinPro) as you could here the delays in extensive CPU processing.

Parallels required you to run as root, while Win4LinPro disallowed root invocation. You were also given the opporunity to configure Windows users, while in Win4LinPro it just masked an administrator behind the scenes.

In defense of Win4Lin Pro, it clearly took away a lot of steps in the normal windows installation which made it clearly easier to install.

For Win4Lin Pro, it would not accepted my laptop Windows XP Pro CD (as it was not SP1 or SP2).
The specs for Parallels stated it would work, however I used anothe Windows XP Pro CD with SP1.
Surprisingly in the activation process, I could not use the Serial Number for my Laptop Windows XP, I had to use the serial Number for my SP1 CD. Not to bother, I own both, and use neither, it was just interesting to see Microsoft reject a valid serial number.

Extending MySQL Capabilities with UDFs, Plugins and Components

Extending MySQL Capabilities with UDFs, Plugins and Components

MySQL offers three different approaches to extending the SQL capabilities with the default product you download and install. These are: User Defined Function (UDF) MySQL Manual MySQL Plugin MySQL Manual MySQL Component MySQL Manual For the purposes of this post I will be using the current LTS version MySQL 8.

Producing One-Sample Z-Test statistics with SQL

Producing One-Sample Z-Test statistics with SQL

The one-sample Z-test determines whether a sample mean differs significantly from a known population mean when the population standard deviation is also known. It is the appropriate test when the population parameters are established — quality control benchmarks, national averages, long-run process measurements — and you want to evaluate whether a new sample is consistent with them.

Switching to JSON Error Logging in MySQL

Switching to JSON Error Logging in MySQL

You no longer need to manually parse the MySQL Error log via scripting and RegEx pattern matching. Using the component_log_sink_json component you can obtain JSON error logging for easier parsing.
