I have been trying to find the time and the resources to get a xen testbed up and working because my hosting company, Rackspace (and before that Slicehost) used xen to power their cloud servers and I thought it would be worth having some experience in that area since I currently depend on it, and even if I do switch providers I will likely be looking for one that provides a xen based solution. My first attempt was when I got a new CPU server/workstation recently. Unfortunately I discovered that xen and Nvidia don't play nice together so I wound up using KVM instead. I am actually glad, because KVM is more flexible and makes possible, if not always easy, to migrate from VMware. There is a definite performance advantage to xen, because the guest and host kernels cooperate.

Anyway, I finally was able to repurpose my old CentOS/VMware server as a Debian/Xen server I started hacking around. I noticed the disk devices in the xen VMs that I created were using /dev/xvda instead of the usual /dev/sda, even though I seemed to remember that on Rackspace (and before that Slicehost) the devices are /dev/sda. I took a look at the MAJOR and MINOR codes on the devices in my xen VMs and the ones on the Rackspace VM, and sure enough, the Rackspace VMs are using /dev/xvda too, they have just changed the name, presumably because that is what people are used to seeing. Next out of curiosity, I tried to fdisk /dev/sda on the Rackspace VM, only it isn't there. When I created it using mknod and tried to fdisk it again I got a permission error. I am sure this is a security thing and I wasn't really worried about it, but I tweeted something about it as a sort of joke. Rackspace responded:

@plicease Could you email details to us? We'll help you figure out what it is. twitter @Rackspace .com

I hadn't put Rackspace in a # or used @ to refer to them or anything I guess they just troll the Interwebs for any mention of them in a sort of proactive tech support? They have always claimed to have fanatical tech support. Is this fanatical though, or maybe a bit creepy? Twitter is a public forum, and I post my tweets publicly so I can't really complain.

For the most part, they have always been quite good, although I have to say they seem to be a wee bit better when I had a dedicated server with them than they are now when I have VMs (there was a period for a number of years between those two scenarios when I had different hosting companies). Bad hardware has caused two of my VMs to go down on two separate occasions occasions (one VM each time). That sort of thing happens from time to time, and I'm not really complaining but over a much longer period, I never had a fault with my dedicated server.

Today when I left the house I noticed it was raining. Then when I was in the train trying to dry off, I noticed it wasn’t raining. Then when I got to St. Leonards and was walking the last leg to work I noticed that it was raining again. I was feeling a bit like Truman when the rain cloud was following him.

I have sort of decided that I want to get an iPhone which makes me feel like a sell out because I think they are stupid. On the other hand I view it as a free iPod touch which would let me watch videos on the train, which currently I can’t do because although over powered, my notebook fails at video when it isn’t plugged into a wall why is that? I’ve noticed that since I started commuting from the Central Coast a lot of my thinking revolves around getting a train which will likely allow me to sit down, and what I am going to do when I get that seat.

Last Friday I went to see Assassins. We were prompted to go see it on account of everyone in my family is a fan of Sarah Vowell and she had a highly amusing anecdote about the musical in the introduction to her highly amusing and well researched Assassination Vacation. I sort of had a celebrity crush on her sometime back. The lighting was really badly done, and the sound was a little buzzy at parts, but several of the actors were actually pretty good. Lee Harvey Oswald, John Wilkes Booth were good, but my favourite was the innately jovial Guiteau.

There is something about flawed somewhat incompetent villains that I find endearing. My favourite cartoon character has always been Starscream, the constantly scheming traitorous lieutenant to Megatron. In watching the new BBC Robin Hood series I immediately took a liking to the Sheriff because of the joy in which he employs his sarcastic wit and sadistic pleasures. Lately, however I am liking Gisborne more and more. His melancholy manner and the way he feels so uncomfortable in almost any situation (but especially when he is trying to Marion) is wonderful to watch. It is somewhat troubling that Guiteau is not a cartoon or legendary villain. He’s a murderer.

I started reading the highly entertaining Linux Hater's Blog. It was indirectly linked to from a /. story, and even though I love Linux as a development platform and for developing web sites, it sucks shit on the desktop, and this guy understands exactly why and explains in a concise but nuanced way, along with a whole lot of entertaining[1] vitriol. The thing is Linux is never going to be a serious player on the Desktop, so it is all fairly academic. I can’t really stand any of the modern user interfaces for an extended period of time. My Mac seems like a relief after a long day using Winblows at work, and sometimes GNOME and KDE are even offer a welcome respite from either or both. So I am picky, that is probably my fault. What is distressing is that user interfaces are getting progressively worse. I spent a day or so using Vista in order to make sure an application at work I was finishing off worked there, and it was a really horrible experience. If I didn’t know better I’d say that they Microsoft was trying to convince me that XP wasn’t so bad after all.

new job

New job starting next Wednesday. I have a good vibe about it. In the interview they were asking me the right sort of questions about Perl. It involves working with Perl in a Linux/SQL/Apache environment which makes me feel like a fish in water. The pay is good too. I will be working hard for the next few months.

I have to think up a secret code name for them. I never really cared for Company 2 as a codename. Nor for the company really.

I was reading the other day about how they (the giant ants[1]) were going to make a game featuring both Sonic and Mario. Not only that, but they were both going to be featured in the title of the game. Growing up with the Nintendo vs. Sega rivalry, this would have once seemed like the moral equivalent to having Darth Vader command the USS Enterprise-K in the Next Next Generation, or having Captain Kirk pilot an X-wing. Times they are a-changing I guess, and where there is a business case anything can happen. Just today I was reading that Dell was going to start selling PC desktop systems with Linux pre-installed, which further confused me: this can’t be the same reality that I’ve lived in for the last 30 years. All of this is way too early for April Fools, so they must be ice skating in hell for sure.

Speaking space opera, I always had this fantasy of quitting my job in corporate America/Australia by declaring “I am a programmer. Like my father before me.” (Tyler can correct me on the inaccuracy of that quote) All this with the Visigoths about to storm Rome in 410, and bring an end to the Empire[2]. The trouble is, my dad is actually a chemist. A pretty damn good one, but although he knows Fortran I wouldn’t really describe him as a programmer. I hope that if it ever does come to that, fate will forgive the necessity of a nice dramatic statement in place of a factually correct one.




  1. Damn you Tyler, I can’t use the word “they” or “them” without thinking about giant ants!

Software

I was researching Wikis using (appropriately enough) Wikipedia just now to see if I could harness the technology for HVOC. While I was at it, I came across a reference to the hacker and free software advocate Richard Stallman, also known as rms. My friend, Richard Ess, also has the same initials; and only a few people know this: the M. in Richard M. Ess either doesn't stand for anything (as in "J Robert Oppenheimer") or it stands for "middle".

Anytime Stallman's name brought up it summons in me a feeling of low intensity rage. If all politics are local, and you live in the world made up of software known as the Internet, which is by its nature global, then you may come to appreciate that the world of software is in fact political. If this is the case than I think it could be fairly said that if Bill Gates were the Rush Limbaugh or Pat Buchanan of software, then Richard Stallman would be Ralph Nader; although I think this is being unfair to Nader, as Stallman is petty and childish (If you believe this to be true of Nader, then maybe it is not unfair).

One of Stallman's pet peeves is that people insist on calling Linux Linux. You will find that I am one of these people, because 1) that is what it is called and 2) even if it weren't I would probably not call it that other name simply to spite Stallman. I won't repeat what he calls it, but I will say that he wants credit for Linux because his software plays a part in the success of Linux. Instead of being happy that free software is being used, he is being petty and demanding credit. This causes divisiveness in the free software community, which if you use my political analogy to software, you can see is prevalent in American politics too.

The other charge is that he is childish. I won't go into too much detail but I read an article about him where the interviewer described an episode where Stallman flipped off a building that was named after Bill Gates. In another episode, he was invited to talk at a conference for free software that was sponsored by a number of free software companies. Instead of being a positive voice, he took the opportunity to attack the sponsors, all of which make money from free software. It is, to an extent, a "free country" so he is free to express himself thus. If I were to analyze his behavior (which I am), I would say that he is resentful of the fact that these companies are making money off of, and getting credit for free software, including free software that he wrote.

If you view that companies are doing a bad thing by exploiting free software commercially, or that they are not being "true" to the free software spirit, or more to the point that they are not properly reverent to Stallman, then this is a limitation of the Copylefted license that not only did he use to release his software; but he even wrote the license and invented the term Copyleft. I actually don't think this is a limitation of the license, although I do think it is a limitation of individuals when they believe that all software should be distributed under the same copylefted license.

Stallman resents the fact that when the PC was born and gave rise to the commercial software industry as it exists today, it lead to what he saw as a decline in his hacker community. I think that everyone in the free software community should recognize and appreciate what commercialization of computers has done for society. I can't think of too many people who like Bill Gates, or his henchman the Microsoft Word Paperclip, but even I have to give him credit for turning the PC into a commodity, and making it widely available. I would argue that a big part of the reason that PCs are so affordable today is that Micro$oft, along with others, such as Apple, have made computers accessible to regular people. The creation of this enormous market has consistently driven the price of PCs down, while at the same time the speed and quality of hardware goes up.

Just to give you an idea, I gave Tyler Tron 2.0 for his birthday, and picked up a used copy for myself on half.com. If you have seen the original 80s movie on which it is based you know that the graphics are limited and simplistic. Those scenes were rendered in a batch process; meaning each frame did not have to be rendered quickly enough to be displayed real-time. This game, by contrast has much more sophisticated graphics and thanks to 3D hardware acceleration, all the frames are rendered real-time.

This is something that free software, which existed long before PCs, and long before Stallman claimed to have invented it, could never do. Free software is good for many things, particularly for constructing server software and for niche application development, and I will quite often choose a free software product over a commercial one based on quality rather than price. On the other hand, there are certain commercial software applications that are hands down the best available, and far outperform their free software equivalent. From my own point of view I would say Micro$oft Word and Adobe Photoshop fit this description. The free software community has put together some good WYSIWYG editors, but with the exception that none of them include a talking paper clip, they just don't have as rich a feature set as Word. As for Photoshop, while The GIMP is quite good, and was adequate for my needs for a long time, it is simply not good enough for professional photographers, and after having learned how to use Photoshop I realize that The GIMP just isn't good enough for my need either.

Fortunately, in this world of extremes, there are also moderates. People who exist somewhere between Bill Gates and Richard Stallman who see the benefit of both free software, the commercialization of free software, and fully commercial software. The best examples, I think, are Linus Torvalds original author of the Linux kernel, which serves as the core of the Linux operating system, and Larry Wall, the original author of Perl. I think people like these have so much more to offer the free software community than the zealots do. I think that it is telling that these two characters still play a major contributing factor to the projects that they created, while Stallman has delegated his coding responsibility to others for a life of advocacy. Those who can, do; those who can't, tell other people what to do.

phone woke me up. reporter daily star. "it's three o'clock morning" i moaned. parts of speach difficult. photographer. desire photographs taken. for interview. vaguely remember reporter from yesterday. mitch gitman. acknowledge affirmative. roll out of bed. stagger bathroom, drench self healing power of hot water. My eyes begin to see objects a little more distinctly and my memory is coming back on line. Yesterday a reporter had interviewed me about the Dorm network "ResComp" or as I like to refer to it "ResInComp." I turn the water off and start to towel off. I had directed him in the direction of an acquaintance Fydor and my friend Tyler, because they were like minded Internet Dorm Dwellers. Mitch had just called me up to ask if they could photograph me using the Internet.

I wonder why he called me up this early as I walk back into my room, when I notice that it is awfully bright in my room for 3:00am. I squint at my alarm clock and hit it with a clenched fist. It changes to 8:14am, which I assume means it is actually 8:04am, since I always set the thing ten minutes fast.

My one time best friend Guthrie "gUe" "In a Pear Tree" Partridge thought that it was pretty funny when my Linux box at the time (Either Figment or Pacific the First, I forget which) crashed and said "Kernel Panic." Now, it wasn't a big deal, it wasn't like I had some critical application running, since the computer was just booting and couldn't find the root partition where it expected to find it. I forget how, but I fixed it. So when I say I don't understand why it is funny, it's not because I've been blinded by techno rage because my computer refuses to work. I just don't know why "Kernel Panic" should be so funny. "What's a matter Kernel Sanders... Chicken?" - now that is funny. Someone please enlighten me. gUe doesn't talk to me anymore (at least not politely) so I can't ask him.

Driving to lunch today I see that the leaves are beginning to change in earnest. There are spots where it looks rather breathtaking, I should have brought one of my many cameras to document it a little bit. Hopefully I will find the time to do it before everything DIES and makes New York look like a miserable dead land of Ice.

Oh yes, and it turns out there is hope for me yet. The purveyors of wisdom at The Company decided not to do the sensible thing and allow me to put both of my commuters at work on the fast Ethernet/ius. Instead of becoming bitter and angry over it, I have decided to go about doing what they want me to do, which is move my web services from my computer to our organization's web server. I still think that it is The Wrong Thing To Do, but the more I think about it, the more I realize that it is actually not too bad a hardship for me to endure.
