Most Expensive JavaScript Ever?
ekran writes "A while ago Opera Software needed more servers. Not just a few servers either — they were planning Opera Mini's growth, implementing Opera Link, and My Opera was also growing quickly.
Most of the major hardware vendors grabbed their specs and came back with offers and sample servers shipped all the way to Oslo for testing. One of the biggest vendors, however, did not do their homework. They shipped the server, but when the Opera sysadmins started up the web-admin interface, they were met with a JavaScript statement that managed to piss off the whole company including the CTO. The script, apparently, locked out the Opera web-browser."
it's not HP as the link to what they actually buy shows they bought HP blades (http://www.digi.no/504306/her-kjores-egentlig-opera-mini&bid=6)
my money is going on Dell.

48V DC is an odd beast, with odd standards going back to the early days of the Bell System.
In a 48V DC system, the positive side is grounded. This is to prevent corrosion on phone lines in the ground that happens more readily if the system is negative ground.
Since positive is ground, the "live" wire is negative, or -48VDC. Since this is the wire you don't want to lick, or allow to touch the chassis when powered, it is colored red in many deployments. The black wire is ground, you can lick* it all you want.
* -48V DC won't really sting you much if you just touch it unless your hands are wet or you touch it with a wet part of you like your tongue.
A bit of exploration gives one possibility. This page, on Dell DRACs , which have a web interface, shows that the web interface supports really only IE and firefox, and those only on 32 bit machines.
Ah yes, Dell Remote Access Controllers have a shitty as hell web interface that only seems to work in IE. I think it's supposed to work in firefox but it never has for me.
Photos.
Some of their ethernet switches block non-IE browsers as well. I forget which is which, but I think the PowerConnect 6000s warn about the browser but let you through, and the 5000s just refuse to let you in when running firefox on linux.
My experience is from a few years ago and perhaps they have fixed their firmware since then, I know I filed a complaint.
Browser detection is almost always the wrong way to do things anyway. Test for existence of specific JavaScript properties/methods on objects to find out if they exist. You can generally check for IE-specific behavior just by testing for the presence or absence of JavaScript properties/methods.
if (document.getElementsByClassName) {
/* IE and old browser version */
elts = document.getElementsByClassName("resulttablerow");
} else {
}
By doing this, you won't have to do a browser check at all and your page will "just work" for any browser that implements either the standards-compliant behavior, the IE behavior, or both. You can do the same thing for CSS properties by trying to add the property, then going and trying to read it back for verification. If it isn't there when you go back and check for it, the browser doesn't support the CSS property.
I'm not familiar with Opera's behavior, but in my experience, roughly 99.5% of CSS and JavaScript that works with FireFox also works with Safari and vice versa (as long as you don't try to use bleeding edge HTML5 or CSS3 features). Any browser check that only tests for FireFox is almost always just guaranteed to make a bunch of users mad for no reason.
