Horror Movie Corner
Halloween is upon us once again, and since this is one of the few holidays in which I write something that is somewhat timely, I figure I should continue the tradition (and this year, I'll actually publish the post before Halloween). A few horror movies I've had the pleasure to view recently:

Adventures in Linux, Paradox of Choice Edition
Last week, I wrote about the paradox of choice: having too many options often leads to something akin to buyer's remorse (paralysis, regret, dissatisfaction, etc...), even if their choice was ultimately a good one. I had attended a talk given by Barry Schwartz on the subject (which he's written a book about) and I found his focus on the psychological impact of making decisions fascinating. In the course of my ramblings, I made an offhand comment about computers and software:
... the amount of choices in assembling your own computer can be stifling. This is why computer and software companies like Microsoft, Dell, and Apple (yes, even Apple) insist on mediating the user's experience with their hardware & software by limiting access (i.e. by limiting choice). This turns out to be not so bad, because the number of things to consider really is staggering.The foolproofing that these companies do can sometimes be frustrating, but for the most part, it works out well. Linux, on the other hand, is the poster child for freedom and choice, and that's part of why it can be a little frustrating to use, even if it is technically a better, more stable operating system (I'm sure some OSX folks will get a bit riled with me here, but bear with me). You see this all the time with open source software, especially when switching from regular commercial software to open source.
One of the admirable things about Linux is that it is very well thought out and every design decision is usually done for a specific reason. The problem, of course, is that those reasons tend to have something to do with making programmers' lives easier... and most regular users aren't programmers. I dabble a bit here and there, but not enough to really benefit from these efficiencies. I learned most of what I know working with Windows and Mac OS, so when some enterprising open source developer decides that he doesn't like the way a certain Windows application works, you end up seeing some radical new design or paradigm which needs to be learned in order to use it. In recent years a lot of work has gone into making Linux friendlier for the regular user, and usability (especially during the installation process) has certainly improved. Still, a lot of room for improvement remains, and I think part of that has to do with the number of choices people have to make.
Let's start at the beginning and take an old Dell computer that we want to install Linux on (this is basically the computer I'm running right now). First question: which distrubution of Linux do we want to use? Well, to be sure, we could start from scratch and just install the Linux Kernel and build upwards from there (which would make the process I'm about to describe even more difficult). However, even Linux has it's limits, so there are lots of distrubutions of linux which package the OS, desktop environments, and a whole bunch of software together. This makes things a whole lot easier, but at the same time, there are a ton of distrutions to choose from. The distributions differ in a lot of ways for various reasons, including technical (issues like hardware support), philosophical (some distros poo poo commercial involvement) and organizational (things like support and updates). These are all good reasons, but when it's time to make a decision, what distro do you go with? Fedora? Suse? Mandriva? Debian? Gentoo? Ubuntu? A quick look at Wikipedia reveals a comparison of Linux distros, but there are a whopping 67 distros listed and compared in several different categories. Part of the reason there are so many distros is that there are a lot of specialized distros built off of a base distro. For example, Ubuntu has several distributions, including Kubuntu (which defaults to the KDE desktop environment), Edubuntu (for use in schools), Xubuntu (which uses yet another desktop environment called Xfce), and, of course, Ubuntu: Christian Edition (linux for Christians!).
So here's our first choice. I'm going to pick Ubuntu, primarily because their tagline is "Linux for Human Beings" and hey, I'm human, so I figure this might work for me. Ok, and it has a pretty good reputation for being an easy to use distro focused more on users than things like "enterprises."
Alright, the next step is to choose a desktop environment. Lucky for us, this choice is a little easier, but only because Ubuntu splits desktop environments into different distributions (unlike many others which give you the choice during installation). For those who don't know what I'm talking about here, I should point out that a desktop environment is basically an operating system's GUI - it uses the desktop metaphor and includes things like windows, icons, folders, and abilities like drag-and-drop. Microsoft Windows and Mac OSX are desktop environments, but they're relatively locked down (to ensure consistency and ease of use (in theory, at least)). For complicated reasons I won't go into, Linux has a modular system that allows for several different desktop environments. As with linux distributions, there are many desktop environments. However, there are really only two major players: KDE and Gnome. Which is better appears to be a perennial debate amongst linux geeks, but they're both pretty capable (there are a couple of other semi-popular ones like Xfce and Enlightenment, and then there's the old standby, twm (Tom's Window Manager)). We'll just go with the default Gnome installation.
Note that we haven't even started the installation process and if we're a regular user, we've already made two major choices, each of which will make you wonder things like: Would I have this problem if I installed Suse instead of Ubuntu? Is KDE better than Gnome?
But now we're ready for installation. This, at least, isn't all that bad, depending on the computer you're starting with. Since we're using an older Dell model, I'm assuming that the hardware is fairly standard stuff and that it will all be supported by my distro (if I were using a more bleeding edge type box, I'd probably want to check out some compatibility charts before installing). As it turns out, Ubuntu and it's focus on creating a distribution that human beings can understand has a pretty painless installation. It was actually a little easier than Windows, and when I was finished, I didn't have to remove the mess of icons and trial software offers (purchasing a Windows PC through somone like HP is apparently even worse). When you're finished installing Ubuntu, you're greeted with a desktop that looks like this (click the pic for a larger version):
No desktop clutter, no icons, no crappy trial software. It's beautiful! It's a little different from what we're used to, but not horribly so. Windows users will note that there are two bars, one on the top and one on the bottom, but everything is pretty self explanatory and this desktop actually improves on several things that are really strange about Windows (i.e. to turn off you're computer, first click on "Start!"). Personally, I think having two toolbars is a bit much so I get rid of one of them, and customize the other so that it has everything I need (I also put it at the bottom of the screen for several reasons I won't go into here as this entry is long enough as it is).
Alright, we're almost homefree, and the installation was a breeze. Plus, lots of free software has been installed, including Firefox, Open Office, and a bunch of other good stuff. We're feeling pretty good here. I've got most of my needs covered by the default software, but let's just say we want to install Amarok, so that we can update our iPod. Now we're faced with another decision: How do we install this application? Since Ubuntu has so thoughtfully optimized their desktop for human use, one of the things we immediately notice in the "Applications" menu is an option which says "Add/Remove..." and when you click on it, a list of software comes up and it appears that all you need to do is select what you want and it will install it for you. Sweet! However, the list of software there doesn't include every program, so sometimes you need to use the Synaptic package manager, which is also a GUI application installation program (though it appears to break each piece of software into smaller bits). Also, in looking around the web, you see that someone has explained that you should download and install software by typing this in the command line: apt-get install amarok. But wait! We really should be using the aptitude command instead of apt-get to install applications.
If you're keeping track, that's four different ways to install a program, and I haven't even gotten into repositories (main, restricted, universe, multiverse, oh my!), downloadable package files (these operate more or less the way a Windows user would download a .exe installation file, though not exactly), let alone downloading the source code and compiling (sounds fun, doesn't it?). To be sure, they all work, and they're all pretty easy to figure out, but there's little consistency, especially when it comes to support (most of the time, you'll get a command line in response to a question, which is completely at odds with the expectations of someone switching from Windows). Also, in the case of Amarok, I didn't fare so well (for reasons belabored in that post).
Once installed, most software works pretty much the way you'd expect. As previously mentioned, open source developers sometimes get carried away with their efficiencies, which can sometimes be confusing to a newbie, but for the most part, it works just fine. There are some exceptions, like the absurd Blender, but that's not necessarily a hugely popular application that everyone needs.
Believe it or not, I'm simplifying here. There are that many choices in Linux. Ubuntu tries its best to make things as simple as possible (with considerable success), but when using Linux, it's inevitable that you'll run into something that requires you to break down the metaphorical walls of the GUI and muck around in the complicated swarm of text files and command lines. Again, it's not that difficult to figure this stuff out, but all these choices contribute to the same decision fatigue I discussed in my last post: anticipated regret (there are so many distros - I know I'm going to choose the wrong one), actual regret (should I have installed Suse?), dissatisfaction, excalation of expectations (I've spent so much time figuring out what distro to use that it's going to perfectly suit my every need!), and leakage (i.e. a bad installation process will affect what you think of a program, even after installing it - your feelings before installing leak into the usage of the application).
None of this is to say that Linux is bad. It is free, in every sense of the word, and I believe that's a good thing. But if they ever want to create a desktop that will rival Windows or OSX, someone needs to create a distro that clamps down on some of these choices. Or maybe not. It's hard to advocate something like this when you're talking about software that is so deeply predicated on openess and freedom. However, as I concluded in my last post:
Without choices, life is miserable. When options are added, welfare is increased. Choice is a good thing. But too much choice causes the curve to level out and eventually start moving in the other direction. It becomes a matter of tradeoffs. Regular readers of this blog know what's coming: We don't so much solve problems as we trade one set of problems for another, in the hopes that the new set of problems is more favorable than the old.Choice is a double edged sword, and by embracing that freedom, Linux has to deal with the bad as well as the good (just as Microsoft and Apple have to deal with the bad aspects of suppressing freedom and choice). Is it possible to create a Linux distro that is as easy to use as Windows or OSX while retaining the openness and freedom that makes it so wonderful? I don't know, but it would certainly be interesting.

The Paradox of Choice
At the UI11 Conference I attended last week, one of the keynote presentations was made by Barry Schwartz, author of The Paradox of Choice: Why More Is Less. Though he believes choice to be a good thing, his presentation focused more on the negative aspects of offering too many choices. He walks through a number of examples that illustrate the problems with our "official syllogism" which is:
So how do we react to all these choices? Luke Wroblewski provides an excellent summary, which I will partly steal (because, hey, he's stealing from Schwartz after all):
Another example is my old PC which has recently kicked the bucket. I actually assembled that PC from a bunch of parts, rather than going through a mainstream company like Dell, and the number of components available would probably make the Circuit City stereo example I gave earlier look tiny by comparison. Interestingly, this diversity of choices for PCs is often credited as part of the reason PCs overtook Macs:
Back in the early days of Macintoshes, Apple engineers would reportedly get into arguments with Steve Jobs about creating ports to allow people to add RAM to their Macs. The engineers thought it would be a good idea; Jobs said no, because he didn't want anyone opening up a Mac. He'd rather they just throw out their Mac when they needed new RAM, and buy a new one.But as Schwartz would note, the amount of choices in assembling your own computer can be stifling. This is why computer and software companies like Microsoft, Dell, and Apple (yes, even Apple) insist on mediating the user's experience with their hardware by limiting access (i.e. by limiting choice). This turns out to be not so bad, because the number of things to consider really is staggering. So why was I so happy with my computer? Because I really didn't make many of the decisions - I simply went over to Ars Technica's System Guide and used their recommendations. When it comes time to build my next computer, what do you think I'm going to do? Indeed, Ars is currently compiling recommendations for their October system guide, due out sometime this week. My new computer will most likely be based off of their "Hot Rod" box. (Linux presents some interesting issues in this context as well, though I think I'll save that for another post.)
So what are the lessons here? One of the big ones is to separate the analysis from the choice by getting recommendations from someone else (see the Ars Technica example above). In the market for a digital camera? Call a friend (preferably one who is into photography) and ask them what to get. Another thing that strikes me is that just knowing about this can help you overcome it to a degree. Try to keep your expectations in check, and you might open up some room for pleasant surprises (doing this is suprisingly effective with movies). If possible, try using the product first (borrow a friend's, use a rental, etc...). Don't try to maximize the results so much; settle for things that are good enough (this is what Schwartz calls satisficing).
Without choices, life is miserable. When options are added, welfare is increased. Choice is a good thing. But too much choice causes the curve to level out and eventually start moving in the other direction. It becomes a matter of tradeoffs. Regular readers of this blog know what's coming: We don't so much solve problems as we trade one set of problems for another, in the hopes that the new set of problems is more favorable than the old. So where is the sweet spot? That's probably a topic for another post, but my initial thoughts are that it would depend heavily on what you're doing and the context in which you're doing it. Also, if you were to take a wider view of things, there's something to be said for maximizing options and then narrowing the field (a la the free market). Still, the concept of choice as a double edged sword should not be all that surprising... after all, freedom isn't easy. Just ask Spider Man.

Linux Humor & Blog Notes
I'll be attending the User Interface 11 conference this week, and as such, won't have much time to check in. Try not to wreck the place while I'm gone. Since I'm off to the airport in fairly short order (why did I schedule a flight to conflict with the Eagles/Cowboys matchup? Dammit!) here's a quick comic with some linux humor:
The author, Randall Munroe, is a NASA scientist who has a keen sense of humor (and is apparently deathly afraid of raptors) and publishes a new comic a few times a week. The comic above is one of his most popular, and even graces one of his T-Shirts (I also like the "Science. It works, bitches." shirt)
I'm sure I'll be able to wrangle some internet access during the week, but chances are that it will be limited (I need to get me a laptop at some point). I'll be back late Thursday night, so posting will probably resume next Sunday.

My favorite podcast, Filmspotting (formerly known as Cinecast), has a great format. They review a recently released movie every week, but they also review an older film that they have, for one reason or another, neglected. The usually choose a theme for these older movies and watch a bunch of them in a row. As such, they refer to them as Marathons, and it makes for some interesting listening, even when you aren't watching along. They've done one for Westerns, Horror, Hitchcock, Screwball Comedy, and many others. Their next marathon (scheduled to start in a few weeks) is for Animation. This is the first one I plan to play along with, in part because I like animated movies and also because I have netflix now and can easily follow along with minimal effort.
They've chosen an interesting list, though I have some reservations. Here's the list:
As I say, it's an interesting list, but I have some reservations. I've seen 4 of the 6 films (assuming Spirited Away is chosen), so this is perhaps not the best one for me to play along with. I am intrigued by Grave of the Fireflies though, and I could certainly revisit Akira (which I saw many moons ago, and don't remember all that much about it except that it was confusing). From what I've seen of these, I think that while they may have chosen films that illustrate the evolution of Animation, I don't know that they've chosen the most enjoyable of the bunch. Akira seems to be an important film for the genre, but it's not especially a walk in the park, for example. The only one I'd say is truly great is Spirited Away. I probably would have also recommended the Cowboy Bebop Movie, which is a very good all around experience. The other thing that might seem a little strange is that Anime seems to be a genre dominated more by series than by movies... but then I could see why these guys don't want to spend 4.5 hours a week watching these series (I don't know how they managed to do as much as they do).
In any case, I plan to play along, so expect some entries in a few weeks discussing the films above.
Update: The Miyazaki film will be Spirited Away. Also added links to my reviews of the films I've watched so far.

Adventures in Linux, iPod edition
Last weekend, my Windows machine died and I decided to give linux a shot. My basic thought was that if I could get a linux box to do everything I need, why bother getting another copy of windows? So I cast about looking for applications to fulfill my needs, and thus found myself on Mark Pilgrim's recently updated list of linux Essentials (Pilgrim has recently experienced a bit of net notoriety due to his decision to abandon Apple for Ubuntu).
So I need something to replace iTunes (which I use to play music and update my iPod). No problem:
amaroK. It’s just like iTunes except it automatically fetches lyrics from Argentina, automatically looks up bands on Wikipedia, automatically identifies songs with MusicBrainz, and its developers are actively working on features that don’t involve pushing DRM-infected crap down my throat. Add the amarok repository to get the latest version. apt-get install amarokAfter taking that advice and installing Amarok, I think that paragraph would be better written as:
amaroK. It’s just like iTunes except it automatically orphans most of your library so that you can't see or play most of your music on your iPod, it doesn't handle video, it can't write to the iPod's podcast directory, and (my personal favorite) if you plug your Amarokized iPod into a windows machine, it crashes iTunes. Add the amarok repository to get the latest version, as the latest version doesn't seem to have those problems.Yes, that's right, I plugged in my iPod and Amarok corrupted the itunes database. I could still use my iPod, but I could only see 256 songs (out of around 1000). It didn't delete the files - all 1000 songs were still on the iPod - it just screwed up the database that controls the ipod. The issue turns out to be that I installed an older version of Amarok, and since Mark recommended getting the latest version, I really can't fault him for this debacle. You see, Ubuntu comes with a few user-friendly ways of installing programs. These are based on what's called "Repositories" which are basically databases full of programs that you can browse. So I fired up one of these installation programs, found Amarok, and installed it... not realizing that the default Ubuntu repository had an older version of the program.
Obviously, I had a bad experience here, but I'm still a little confused as to how Amarok is a valid iTunes replacement. Even with the latest version, it still has no support for videos (and the developers don't plan to either, their excuse being that Amarok is just a music player) and it's podcast support isn't ideal (
Despite the problems, I find myself strangely bemused at the experience. It was exactly what I feared, but in the end, I'm not that upset about it. There's a part of me that likes digging into the details of a problem and troubleshooting like this... but then, there's also a part of me that knows spending 5 hours trying to install something I could install in about 10 minutes on a Windows box is ludicrous. All's well that ends well, I guess, but consider me unimpressed. It's not enough for me to forsake linux, but it's enough to make me want to create a dual boot machine rather than a pure linux box.
Update: In using Amarok a little more, I see that it supports podcasts better than I originally thought.

The Death of Sulaco
I have two computers running here at Kaedrin headquarters. My primary computer is a Windows box called Sulaco. My secondary computer is running Ubuntu Linux and is called Nostromo. Yesterday, Sulaco nearly died. I'll spare you the details (which are covered in the forum), but it started with some display trouble. It could have been the drivers for my video card, or it could have been that the video card itself was malfunctioning. In any case, by this morning, Sulaco's Windows registry was thoroughly corrupted. All attempts to salvage the installation failed. For some reason, my Windows XP CD failed to boot, and my trusty Win 98 floppy boot disk wouldn't let me run the setup from the XP CD (nor could I even see my hard drive, which had some files on it I wanted to retrieve).
To further complicate matters, the CD burner on my linux box has always been flaky, so I couldn't use that to create a new boot disk. However, I did remember that my Ubuntu installation disk could run as a Live CD. A few minutes of google searching yielded step-by-step instructions for booting a Windows box with an Ubuntu Live CD, mounting the Windows drive and sharing it via Windows File Sharing (i.e. Samba). A few minutes later and I was copying all appropriate data from Sulaco to Nostromo.
For all intents and purposes, Sulaco is dead. She has served me well, and it should be noted that she was constructed nearly 6 years ago with turn-of-the-century hardware. I'm actually amazed that she held up so well for so long, but her age was showing. Upgrades would have been necessary even without the display/registry problems. The question now is how to proceed.
I've been fiddling with Linux for, oh, 8 years or so. Until recently, I've never found it particularly useful. Even now, I'm wary of it. However, the ease with which I was able to install Ubuntu and get it up on my wireless network (this task had given me so much trouble in the past that I was overjoyed when I managed to get it working) made me reconsider a bit. Indeed, the fact that the way I recovered from a Windows crash was to use linux is also heartening. On the other hand, I also have to consider the fact that if someone hadn't written detailed instructions for the exact task I was attempting, I probably never would have figured it out in a reasonable timeframe. This is the problem with linux. It's hard to learn.
Yes, I know, it's a great operating system. I've fiddled with it enough to realize that some of the things that might seem maddeningly and deliberately obscure are actually done for the best of reasons in a quite logical manner (unless, of course, you're talking about the documentation, which is usually infuriating). I'm not so much worried that I can't figure it out, it's that I don't really have the time to work through its ideosyncracies. As I've said, recent experiences have been heartening, but I'm still wary. Open source software is a wonderful thing in theory, but I'd say that my experience with such applications has been mixed at best. For an example of what I'm worried about, see Shamus' attempts to use Blender, an open source 3d modeling program.
My next step will be to build a new box in Sulaco's place. As of right now, I'm leaning towards installing Ubuntu on that and using one of the various Windows emulators like WINE to run the windows proprietary software I need (which probably isn't much at this point). So right now, Nostromo is my guinea pig. If I can get this machine to do everything I need it to do in the next few days, I'll be a little less wary. If I can't, I'll find another Windows CD and install that. To be perfectly honest, Windows has served me well. Until yesterday, I've never had a problem with my installation of XP, which was stable and responsive for several years (conventional wisdom seems to dictate that running XP requires a complete reinstallation every few months - I've never had that problem). That said, I don't particularly feel like purchasing a new copy, especially when Vista is right around the corner...
Bear Pajamas & Kigurumi
A few weeks ago, I wrote about the bear pajamas that Lain often wears in Serial Experiments Lain, wondering if it was perhaps a cultural thing or maybe an Anime convention. Several people commented, and commentor Lily posted an interesting explanation yesterday:
These pajamas are indeed a cultural thing in Japan. It's a part of Japanese street fashion and the costumes are called kigurumi. People wearing them are called kigurumin. There are a few firms in Japan that produce these costumes, the most popular one of them is Sleeper's.Interesting. Lily also links to a page from their site which has a bunch of examples (no bears, though). A brief check of Wikipedia yields some more info:
Kigurumi (着ぐるみ?) is the Japanese name for costumed animal characters. The name comes from the Japanese term (着る - kiru: to wear) and (縫いぐるみ - nuigurumi: a stuffed toy animal).To wear a stuffed toy animal. Heh.
Where am I?
