How To Make A Rotating Fly Sparge Arm For All Grain BrewingOctober 2nd, 2010Ever since I started brewing all grain beer, I’ve wanted one of those cool rotating fly sparge arms. They revolve around and distribute water on your grain bed so all the precious sugars are washed from the grains.

Whichever you prescribe to; this is a cool little project! Read on and I’ll show you how to make a DIY rotating sparge arm. Windows Server 2008 Replacement of ProxyCfg.exeAugust 24th, 2010When setting up a secure server farm you always want to filter egress traffic. This means that all outbound traffic is blocked by default, including the web traffic from the servers. When surfing is required for drivers and downloads, this is usually handled by setting the proxy in the Internet Explorer options. However if you want certain processes / services like Windows Update to automatically retrieve updates and wait for manual approval, the next time you login. You need to set a proxy server up and force the Local Machine to use it. The setting in the IE properties page is for the Current User only. Phone Charger Using A 7805 Voltage RegualtorAugust 18th, 2010I recently replaced my Blackberry Curve with a Verizon Incredible. I soon found that the battery life was the only thing that wasn’t incredible about the phone. Owning a smart phone like the Incredible, Droid X, Apple iPhone or even a Windows Mobile is a paradox; because the more you use the phone the quicker the battery drains. Newer smart phones make the phone more useable than ever before, which means after a few hours the phone is dead. Renaming VMWare Files In Virtual CenterFebruary 24th, 2010When you rename a Virtual Machine in VMWare’s Virtual Center the display name changes, but the files in the datastore do not. The .vmx, .vmdk, .nvram, etc… files retain the original name you gave them when the Virtual Machine was created. This presents a problem if you ever need to back track and figure out what the files are for. A Simple PHP mail() Function For Testing SMTP DeliveryJanuary 9th, 2010Making sure mail is sent properly from a PHP website is a bit difficult when it’s not your server, like shared hosting. You never have access to the mail logs, so you can’t see mail moving. I host several websites on shared hosting and recently found my CMS was not sending emails to me. So I opened a ticket and I concluded it to be a SNAFU. Dell OpenManage Problem – Hangs at Precopy PreparationJanuary 7th, 2010When you purchase a Dell server you can purchase the Open Manage software, so they ship you media. OpenManage is the software that installs the maintenance partition and the automated install of the operating system as well as firmware updates.

How To Save A Webpage In HTML To A File In VBScriptDecember 14th, 2009I had just finished working on a project where I needed to programmatically get a web page and save the HTML to a file. I started toying around with some code I used for parsing XML and totally rewrote the code. I found that I kept getting an error of “Microsoft VBScript runtime error: Invalid procedure call or argument”. I couldn’t understand what was going on. I was passing the parameters correctly to the File System Object, but I kept getting the error. All FSO was doing was creating a file and writing the string out. So I checked the length and then started writing the left(string,number) and found it was a character that was in Unicode. So I wrote a Unicode to Ascii function that is not all that efficient, but it is very effective. The sample code below will get a webpage from Google and save it to a file. Mastering Permissions with icacls.exe Command thru the GUIDecember 11th, 2009The key to mastering permissions at the command line in Vista and Windows Server 2008 Server is learning the icacls.exe command. With the introduction of Windows Vista, you can no longer select multiple items like folders and files and apply permissions to a group of objects. The recommended way is to use the command line and the icacls.exe command. Mac OS X Permissions Problems with Window Server 2003 R2December 8th, 2009Recently I found a problem when using Mac OS X and Windows Server 2003 R2 as a file server. The problem exists in the permissions that are applied to user folders. When applying permissions to shares you normally start out with a very restrictive permission structure at the top. As you create the folders you add permissions for users and groups to permit and restrict access for others. This structure of permissions is very common in dealing with corporate shares. We also share the folder with ‘domain users’ only having change or modify access to the entire share. This eliminates people applying their own permissions and locking everyone out including themselves. This is a common task for a network admin in setting up permissions. |
