iPhone IMAP Folder Re-Synchronize

If you have changed the folder names on your mail server, and they do not correspond to the names appearing on your iPhone you can simply do the following to synchronize them. Enter the email settings menu, select the email account that you have changed the folder names of, and deactivate the account. DO NOT DELETE THE ACCOUNT. Then simply re-activate the account. Your folder names will instantly synchronize when you enter the mail application.

Brown’s Gas Electrode - Series Cell Design

To be technical it doesn’t matter what material your electrodes are made of, just make your electrolyzer common ducted; one gas output hose.

The material of the electrodes matters regarding corosion. If you use copper your water will turn green as it oxidizes extremely quickly. The simply solution is to use a corosion resistant material. Just use stainless steel. The higher the nickel content of the stainless steel, the more corosion resistent the electrodes will be.

As for using electrodes versus plates, if you want an efficient electrolyzer do not use electrodes. Use plates and connect many cells in series. You want no more than 2.2 Volts per cell. Cell in series experience voltage division, therefore add enough plates to reduce the voltage according to the power supply you are using.

Electrode electrolyzers are antequated and inefficient. The series cell design by Yull Brown is the most efficient electrolyzer design period. This is why common ducted oxyhydrogen is called Brown’s Gas nowadays, and not Rhodes Gas. William Rhodes was the first person to patent a common ducted electrolyzer, but he used cylindrical cells, which is relatively innificient. William Rhodes confirmed that Yull Brown’s series cell design is superior.

To clarify things, Brown’s Gas is just a name for common ducted oxyhydrogen. Oxyhydrogen is a 2:1 proportion of hydrogen and oxygen. The common ducting just means having one gas output hose.

Cheers to simplicity

Nagios Virtual Server Monitoring in 15 Minutes - Intro

Nagios allows you to graphically monitor your virtual servers from a single web page. No longer will you have to load each individual website or web service in order to verify consistent operation. Nagios can be downloaded directly from their website at:

http://www.nagios.com

On the Nagios homepage is a link to a 15 minute tutorial, which is relatively straight forward, and works like a charm. My next blog post will cover the same material that is included in their 15 minute tutorial. In this post I want to briefly discuss which guest operating system to use for maximum stability. I highly recommend Ubuntu JeOS for your virtual OS specifically because the kernel works flawlessly with the host operating system. To recap, I currently use Debian Etch as my host OS, and with JeOS as the guest the host CPU load is only active when the guest is actually processing data. I previously used Debian Etch also as the guest OS, and it would have a constant CPU load on the host. This was not at all desirable, and with a quick transition to JeOS the problem was swiftly resolved.

The first step to get Nagios up and running in a VirtualBox guest OS is to install a clean JeOS in a new guest OS.

Step 2 is setting up Nagios. You can follow the 15 minute tutorial on their website, which is indeed perfect, but I will also post the procedures asap.

Windows is a CPU Hog Versus Linux

Seriously I have 4 guest Linux operating system running at the same time, and the host CPU is not nearly as busy as when a single Windows OS is running. Windows literally consumes the same amount of CPU power as maybe 10 Linux operating systems running simultaneously. I use Windows XP in seamless mode to have the benefits of browser compatibility checking, and other Windows only applications; the CPU requirements of Windows is simply tremendous.

Although you can significantly reduce your Windows CPU requirements by turning off the page file system. Frankly on a machine with over 2 Gigabytes of ram, the page file system is simply not required.
