Installing VNC

VNC is not necessary as the default installation provides a VNC server on the main desktop window.

MacOS Theme

Activate the theme

Change the button order

GConf editor: Being a Mac OS X fan, I like my Window buttons to “look like” the Mac OS config. This is an easy change with Metacity. Start the Configuration Editor from the System Tools Menu, from the command-line run gconf-editor. Locate the following setting in the navigation tree: apps -> metacity -> general -> button_layout To make Metacity place the window buttons in the same location as on MacOS set the value to: “close,minimize,maximize:menu”

Anti-virus Rankings: October 2009

Posted on

A new report from AV-Comparatives tested 16 current anti-virus/anti-malware (AV/AM) products against a battery of current malware to see how well each product performed.

The results? None of the AV/AM products received a rating of “very good” (the highest rating), but several performed well. These received their Advanced+ rating (the highest rating) (listed in no particular order): eScan, Symantec, Microsoft, F-Secure, Kaspersky, and Bitdefender.

My favorite? Microsoft Security Essentials, which is free for non-commercial use.

Find absolute position of an element

Posted on

While working on a project, I discovered that I needed to find the absolute coordinates of an element in a page in order to dynamically position another element before showing it.

A quick Google search yielded this gem from quirksmode.org: JavaScript – Find position.

Here’s the condensed code:

/**
 * Determines the absolute position of an element
 *
 * @author Peter-Paul Koch
 *
 * @see http://www.quirksmode.org/js/findpos.html
 *
 * @param object obj The element whose absolute position is to be found.
 * @return array An array with two elements: 0 is the left position, 1 is the top position.
 */
function findPos(obj) {
	var curleft = curtop = 0;

	if (obj.offsetParent) {
		do {
			curleft += obj.offsetLeft;
			curtop  += obj.offsetTop;
		} while (obj = obj.offsetParent);

		return [curleft,curtop];
	}
}

Texting while driving > drunk driving

Posted on

Seth Godin: “The data shows, for example, that texting while driving is more dangerous than driving drunk. It doesn’t feel that way, of course, but will you respect the data and stop, cold turkey?”

e.g. v. i.e.

Posted on Updated on

When giving an example, it can be confusing which abbreviation (e.g or i.e.) to use. The following should make things clear:

The abbreviation e.g., meaning “for or as an example,” comes from the Latin expression exempli gratia (“for example”). Use it when you want to list a few typical examples of the thing mentioned: I have the laboratory equipment, e.g., [not i.e.] beakers, thermometers, and test tubes, that we need. Do not end a list that starts with e.g. with etc. The abbreviation i.e., meaning “that is, that is to say,” comes from the Latin expression id est (“that is”). Use it when you want to give a more precise description of the thing mentioned: The hearing, i.e., [not e.g.] the preliminary hearing, is set for noon Friday. Two periods punctuate e.g. and i.e. in U.S. English, whereas they may be unpunctuated in British English. Surround these abbreviations with commas.
