A Play on words: Gold Standard... Standard Oil... Written by Michael Mandiberg (Michael [at] Mandiberg [dot] com) Lives at http://www.turbulence.org/Works/oilstandard Oil Standard is a 2006 commission of New Radio and Performing Arts, Inc., (aka Ether-Ore) for its Turbulence web site. It was made possible with funding from the Jerome Foundation and New York City Department of Cultural Affairs. ################### BARRELS AND GALLONS ################### 1 Barrel = 42 Gallons ############ INSTRUCTIONS ############ 0. Read the entire instructions before installing 1. If you do not have the Firefox browser, you will need to download and install it from: http://www.mozilla.com/firefox/ 2. If you do not have the Greasemonkey extension installed, you will need to download and install it from here: http://greasemonkey.mozdev.org/ What is Greasemonkey? Greasemonkey is an official extension for Mozilla Firefox that allows the user to change the look, content, or function of a webpage, by writing client side DHTML into a page. The Greasemonkey extension makes Oil Standard possible. You can find out more here 2.5 Restart Firefox (Quit the application and open it again) 3. Click on the link below to go to the Oil Standard script. You should see an "Install" button on the upper right of your browser window. Click install. Oil Standard Script: http://turbulence.org/Works/oilstandard/oilstandard.user.js 3.5 Browsing pages other than Oil Standard: Pages with prices on them! For Mac OS X, you may need to refresh the pages you are browsing (sometimes you need to do this twice) For Win XP, and Linux you may also need to restart Firefox (again!) 4. The first page you browse after installing the script will ask you whether you want to see prices in Dollars-and-Oil, or Oil-Only. Click "cancel" for Oil-Only, otherwise, click "OK" or hit enter for Dollars-and-Oil. Reset Preferences: Too reset the Dollars-and-Oil, or Oil-Only preference, please visit the Reset Preferences page, where you will be prompted again to choose. Disable the script temporarily: Disable the script via the Greasemonkey menu in the bottom right corner of your browser. See the little Greasemonkey: clicking on the monkey once will disable Greasemonkey (clicking again, will re-enable it.) De-Installation Instructions: Remove the script by right-clicking (mac or pc)/control-clicking (mac) on the little monkey, and selecting "Manage User Scripts." From here you can remove the script. ########### Change Log: ########### v0.2 Oil price data source went offline; switched to different source Added new month calculation to make sure the script is using the 60-90 futures price ############# Known Issues: ############# When there are mulitple Million/Billion prices in succession, it ignores every other million suffix. #################### Future Improvements: #################### Set up the data retreivals to pull every hour, rather than every page load Add other currencies in addition to USD */ (function () { oilEntriesArray = new Array() oilLinksArray = new Array() // set the styles addGlobalStyle('.oillink { color: #996633 ! important;
