Virtualization

I've always been rather curios about virtualization technologies and what they can do for me and tonight I had the chnace to delve a little deeper that I have in the past. A cusory study of the technologies out there reveals two major types (I'm not considering emulation) and one , how should I put this, puculiar technue.

Read more after the jump.

Regular virtualization entails running a Virtual Machine Monitor (VMM) on a host that traps certain "un-virtualizable" CPU calls that are then handled in software. These calls are referred to as Domain (or Ring) 0 calls.

Paravirtualization requires the guest OS (the one running under the VMM) to simply not make these Ring 0 calls. So a modified version of the guest operating system is required.

Cooperative extends the theory of coroutines [wikipedia.org] to the Operating System level. In this scenario both cooperating systems are modifed; the guest directly and the host via special drivers.

All three implementations utilize virtual devices (screen, keyboard, drives, network, etc.) for the guest Operating System. Interesting stuff. For more information I would checkout Wikipedia [wikipedia.org] (as always), coLinux [colinux.org] and XenSource [xensource.com].

ER Homicide

ER Heart Attack Ruled Homicide [findlaw.com]: This was quite a surprise. When I first read the digg blurb I thought, no way they actually ruled this a homicide, someone's sensationalizing. So I followed the article trail until I saw the actual verdict form and sure as sh!t it was a homicide. I wonder what kind of repercussions this will have within ERs? Probably worse care for people who don't complain of heart attack symptoms.

Decriminalize Pot: Prison Room Needed for Pedophiles & Politicians

This is an interesting article...it makes sense. I like the part about Friedman being a realist, partly because I agree with him. Note: he doesn't advocate the legalization of marijuana, just the decriminalization (i.e. how much you have on you, etc.).

How about that name...Kinky

Texas Ind. gubernatorial candidate Kinky Friedman for the decriminalization of marijuana to avoid further clogging state prisons with nonviolent offenders. "We've got to clear some of the room out of the prisons so we can put the bad guys in there, like the pedophiles and the politicians," said Friedman, a humorist and author.

iTunes 7

iTunes 7 [apple.com]: This was released yesterday (or the day before) and overall I'm so-so about the whole thing. There are some cool new features, specifically the Coverflow cum Cover Browser view. I like the new iPod status view also, it's a lot more informative. And yes, the sidebar is better laid out than previous versions.

Now for the cons. So far I've only experienced two problems, one minor the other major. The minor one has to do with album art. For whatever reason iTunes couldn't (or wouldn't) pick up art for a lot of songs. So I spent about 2 hours adding album art (mostly from Amazon [amazon.com]) and correcting a lot of the metadata problems I had. The major problem I'm running into is iTunes not using my left speaker. What? Yes, iTunes will drop my left channel very frequently. At first I thought it was a loose cable, but Guild Wars [guildwars.com] confirmed my speakers were working just fine. I'm also able to play sounds via my left speaker while iTunes is playing on the right/ignoring the left. However, I do have a crappy workaround, pause the song and then hit play. Apparently this will poke iTunes into picking pu the left channel.

Bad Apple!

Billing = Stupid

Why can't businesses get billing right? Case in point, I cancelled my Comcast cable service. They told me it would be cancelled on 9/2/2006, okay that's fine. Then I get a bill for service from 9/9/2006 to 10/9/2006, WTF? I called them and they said, "Oh yeah, that's our automated billing system. You can just ignore that bill."

My question to you, Ann Landers, is why can't the billing system see that my service was turned off on 9/2/2006 and just send a final notice? Stupid...

Moving Sucks: Part 3

I decided to go with Perry Moving [perrymoving.com] for a couple of reasons.

  1. Local
  2. Small company
  3. Easy to work with
  4. Personable
  5. Good quote in writing

They came in just under $2500 after high-balling the estimate. Because of my unique situation I really wanted someone to come out to my apartment to see what I wanted moved and these guys were the ones that volunteered to do just that. I had requested others come out, but no one was really receptive, even the ones that advertise on-site estimates as what they do.

Obligatory 9/11

I still remember 11Sep2001 like it was yesterday. There are only so many days in my life that I can say that about, my wedding, college graduation...you get the idea. I was going to class [rit.edu] in upstate NY when one of the secretaries put a TV outside my department's office. At first no one knew what was going on...then we all sort of tuned into the TV at the same time. My first thought was they were showing clips from some new movie. Weird I thought that, I guess it was just hard to fathom that these images were real.

Then my fiance (now wife) called me to let me know what was going on. I guess she was at home watching the news while I was driving to class. Five years...

This being upstate NY almost everyone had relatives/friends in Manhattan and other places within the city. Needless to say it was quite emotional because no one knew if their relatives were caught up in everything or if they escaped. I had one friend who's uncle worked on one of the higher floors of the first building (I can't remember which building). Coincedence as it was he just decided he didn't want to work that day and took the day off. I don't think luck like that happens very often...

The entire week after that was quite surreal to say the least. I would blog more, but it's late here on the east cost.

Zombie in the family

Zombies [wikipedia.org]: I guess technically they are undead, right? Well isn't an undead a corpse that has been re-animated aka "brought back to life"? If so then my uncle-in-law is a zombie and I'm officially related to one. He was technically dead for a while, but he came back (that's a good thing). At least getting him holiday gifts [brains4zombies.com] will be easy now.

Moving Sucks: Part 2

Perry's quote is kind of in. They quoted me $3K, but then I reminded them of some stuff and they are supposed to be getting back to me on Tuesday.
