Prep the Exit Music

Started a new job this week. The motivational speech from the .com's owner was "if you're not working 80 hours here, let me know. I'll write your a letter of recommendation and get you out of here."

So, alas, I'm going to fade away into work. I'll let the two most nerdcore l33t play the music as I sign off into the sunset.

You know I never post YouTube videos on this blog, right? Right? So trust me when I say this is deserving of breaking my streak.

Until later...

Crystal Chair

I remember, still quite distinctly, one particular moment in the December of 2002. My job wasn't what it once was, and I was starting to contribute more into some random open source projects. I wanted to see what game engines "looked like," so I downloaded the developer documentation for CrystalSpace on my (now destroyed) iPAQ. It was December however - and of course I had to do a blitz of Christmas shopping.

While walking all over the mall's green turf, I tried to read the CrystalSpace HTML docs. Finally I took a break and crashed in a lounge chair inside a Von Maur and poured through half the pages I had sync'd. It was in that chair that I was first turned on to CrystalSpace's automagic "smart pointers." When things finally clicked about factory design patterns. When I finally saw how platform-independent file mounting could work. Things largely fit into place for the first time in my head, and a rush of Computer Science courses that were starting to leak out of my brain finally kicked into place. It all weirdly made sense.

I still think of that December of 2002 whenever I pass by that chair. Last year, before I aged another decade, I provided myself with a crap-or-get-off-the-pot objective: to finally have a working game out by February of 2007 or otherwise just give up the ghost. While I did some extensive hacking, spent a lot of late nights and tried to do it, in the end I just wasn't able to produce the goods. I have a partially completed project out there, but in the end I wasn't able to make it happen. I finally gave up the daydream.

I passed by the chair yesterday and thought about how fall was coming soon. Christmas shopping season. And how I'm not going to be perched in that chair pouring over docs anymore.

Sitting Upright with Tux

I saw the weirdest thing in a local putt-putt establishment today. Sitting front-and-center was an upright arcade version of an old favorite, Tux Racer.

Everyone in my family, young and old alike, has played a more updated version of Tux Racer on my Linux box at home. PlanetPenguin Racer was the more "finished product," granting desperately needed functionality and map layouts to its elder version. I'm used to it being an open source game on every Linux distro that even two year olds love to play.

Evidentially Roxor Games turned this into an upright. It was so weird seeing the familiar Tux splash screen behind a quarter slot... I had to do a double and triple take. And then take a crappy cell phone photo. But it was fantastic to see it occupying floor space. It's like the smell of roast beef and mashed potatoes when you walk through the front door. Not the front door of an arcade... the front door of... crap, forget it.

It was just cool to see.

Best Intentions

I seem to have hit an interesting cycle of professional life. Hire, work 70 hour weeks, burnout. Hire, 70 hour weeks, burnout. My independent development fits into the cycle. When I did work for Planeshift I was in the burnout phase - but then I ran out of time to hack when I started to look for new jobs in the "quit" phase. I lost my Planeshift development responsibilities and instead started flailing about in my new (paid) job.

Recently I went through another burnout period, which yeilded the beginnings of ConsultComm version 4 and DeskBlocks. But ultimately before I was even finished I started to interview for new jobs, quit my old one and move on to the flurry of a new corporate projects.

I'm starting the new job soon, and I'm sure that means my open-source development will once again need to go on hold for a bit. I'm hoping to finish my latest round of ConsultComm bugfixes first, so I can at least leave with a clean conscience.

Paul Graham wrote a good article that pretty much explains the above circumstance in his article “Holding a Program in One’s Head”, which pretty accurately reflects the difficulties of hacking. Code often exists like a house of cards in your head, and one weak wind can send it all into collapsination. It's really bad in the office, when random walkby's and phone calls are pretty much modus operendi.

At least I'm starting over again. And a fresh start means I might just make it happen this time, right? Right?

We Suck Less Than Our Competition!

My head is a cloud from the latest plague that I caught, so I'll make this disjointed and brief.

Everyone (myself included) has been caught up in the Linux for the desktop craze. I do use Linux as my primary desktop 95% of the day, and the other 5% is either a) scanning b) iTunes or c) gaming.

However there are several things that I have grown... calloused... towards. Audio can be wonky at times, with either devices being exclusively reserved. Things will become completely unresponsive during high I/O loads. Still, it's a developer's panacea... things work sensically, have an easy interface and are interoperable.

Still, I can understand why Con Kolivas was frustrated. He did his best to fix up CPU scheduling, make things more desktop-friendly, and in the end his kernel patches were nibbled on and digested into someone else's mainline patch. I can see both sides of the story at times... but I think advocates like Kolivas are desperately needed in the Linux desktop world. Especially when it comes to speed. His argument that our gajillion-gigawatt processors should be cutting through our daily chores like cake... but instead we're dealing with the same lag time as the "desktop search engine" indexes every freakin' file on our 1 TB hard drive.

A familiar notion nowadays is that of the early zygote of a hacker... addicted to the Amiga 500 or Commodore64. Kolivas brings an interesting perspective on why: hardware no longer sells. We're dealing with the same scraps as we had before, just with increasing amperage. Hardware is sold because of the OS, where the hardware was pushing the OS in the late 80's. And so it has been ever since.

Or maybe not. Take a look at the XO Laptop from the One Laptop Per Child project. Do you care what operating system it runs? Nope, the hardware is the thing that drives the device. The OS reflects the hardware's abilities and limitations, but in this instance "operating system" is an abstract notion. You don't care that it's running Linux, or Windows, or OS X... just that it's linking together a mesh network of 50 kids over 20 square miles.

Notice it has a "view source" key? Kids can evidently take a look at the current running program's source code on-the-fly, in hopes that they'll want to peek under the hood and maybe hack a little.

Sounds like OLPC is spawning a new generation of Amiga 500 hackers, doesn't it? Both stood to be inspired by "cheap, cheerful, unique" computers that spawned their interest as kids. Here's to hoping that we're encouraging another generation of Kolivas'.

My Cheydinhal Home

I've been suffering from pretty extreme headaches for the past five weeks, so I decided to take a break from... well... everything and try and relax. Part of that relaxation involved finally finishing the main quest & guild quest in Oblivion. It only took fourteen months - better late than never!

Things have been so crazy busy that I haven't played much of anything at all since I walked away almost exactly one year ago. Damn... where does the time go? I've been doing more casual gaming since that fateful summer in 2006 - thanks to Nintendo's solution to gaming in a bathroom stall. Now I can fill even the most narrow of crevasses in time with some match-three variation.

To any point, I finally finished the important quests in Oblivion. I finally trucked back to my home in Cheydinhal, put all my memoirs up for display on my shelves, read a few final tomes I had sitting on my desk, visited a few more scenic locales, then went back to reside My Cheydinhal Home en perpetuity. It was hard to give up, but after a solid three days of gaming I was ready to finally put the DVD-ROM away.

It's been hard to code with the headaches, but I've been trying. I'm working on finishing up Deskblocks and rolling out a point release for ConsultComm. It's just really, really hard to concentrate and code when it feels like a titanium spork inside your dura mater is trying to shovel its way back out through your skull.

Wow. Just..... wow.

I was always a big fan of ReiserFS. It did a good job on filesystem recovery from sudden calamity, and was great with metadata over many small files. I moved to ext3 recently, despite being incredibly slower, mainly due to the more cautious journalling features.

I heard about Hans Reiser's wife, him being a suspect and his friend admitting to murder of eight other people. But Wired's article on the subject is an unbelievable piece of art. By juxtaposing code snippets of ReiserFS with the crescendoing story line (especially if you recognize the code), there is an amazing amount of suspense and revelation that works in tandem to the first-hand narrative. Reading
+ if (!JF_ISSET(node, JNODE_HEARD_BANSHEE))
+ warning("nikita-3177", "Parent not found");
gave me absolute goosebumps.

A Package On Your Doorstep

I first started working with CrystalSpace in 2003. Back then compatibility would change from version to version, building CS was a regular task and CEL was still an up-and-coming project.

Then this January the team announced the first stable release of CrystalSpace; one feature-complete and ready to be production ready. It's amazing how mature the project has become since then... documentation has flourished, CEL has become a fantastic development framework, titles can be developed with little to no coding and Blender integration is now ready for prime time and sponsored by the Blender project itself.

Not only that, CrystalSpace has finally hit the prime time: binary packages are now widely available on most Linux distros. Debian has been carrying packages for a while, but now native SuSE RPM's are available via PackMan.

No, you shut up.

Now people can develop entire titles while only focusing on content creation and scripting, allowing people to focus on what makes a game a game. Not only that, there are copious templates and examples for how to build projects. And you no longer have to build packages every night. And it's open source and readily available. It blows my mind.

I've Never Been So Excited for an Apricot

Blender has been the model editor of choice for CrystalSpace for a long, long time. Most of my CrystalSpace documentation has revolved around using Blender to create content for CrystalSpace code. The two together are like peanut butter and bananas. Fantastic.

Recently Jorrit made an exciting announcement on behalf of the CS team - Blender and CrystalSpace are partnering to build Apricot, an independently developed and completely open game title. To fully understand my unbridled enthusiasm you have to understand Elephants Dream, originally called Blender's project Orange. This was an open movie project - a full movie title with all content released under a flexible Creative Commons license. Textures, models, all production files are freely available. This did unbelievable things for Blender. Not only did this give users access to professionally generated content, new documentation and a whole new realm of tutorials it also pushed the envelope for Blender itself. Orange generated demand for whole new genres of features, and kept the Blender development team pushing point release after point release to keep up. If I recall correctly, Blender's hair generation system was largely built due to demands made by artists creating content for Elephants Dream. Not only did the movie promote Blender, it made Blender a production-quality product that could demonstrate it was ready for prime time.

The same envelope is getting ready to be pushed for CrystalSpace now. That's where my unbridled enthusiasm lies; CrystalSpace has been a commercial-quality 3D engine for a while now, but now every stage of the production process will be thoroughly tested and fleshed out. While I have no doubt that this project will result in enhanced functionality grown by the demands of the game developers, I'm most excited about the tool chain being completely fleshed out. In my mind while the Blender exporters for CS were fantastic, all the corner cases hadn't been completely covered. With Apricot, model exporters should be polished, skeletal animation should be more integrated into Blender armatures, physics should be more strictly related to Blender riggings and meshes should have attributes that more exactly equate to CrystalSpace equivalents. This should make the entire end-to-end content generation process as smooth as a polished stone.

Nothing like a real-life, production quality project will take the edges off of the various and sundry tools used for development. It's amazing how much one will forbear when it's not a "huge issue," but when you encounter the same "not a huge issue" twenty times a day it suddenly becomes something worth tackling. Ideas and features may be the result of inspiration, but the remaining 99% of time spent refining a project is sheer perspiration. I'm looking forward to both projects' continued trial by fire, and seeing what has been forged once the fires have quieted down.

What the NDS and iPhone Have In Common

This past weekend I saw a copy of Opera for the Nintendo DS just idly sitting on the store shelf. I picked up a copy and thought to myself "damn, I'm out of the loop. I didn't even realize this was out yet!" Evidentially I picked up an early copy - the release wasn't reported until the following Monday.

I'm surprised how much I'm using the browser. I didn't think I'd be the type to roam through my house checking random sites on the NDS. But in an age of ubiquitous WebMail and continuously streaming blogs, a device that allows you to quickly scroll through snippets of online text is actually pretty useful. There turns out to be plenty of opportunities where I "just want to check something," such as see if a webcomic has been posted for today or check if I've received new e-mail at work. Instances not exactly worth booting up a laptop, but perfect for just cracking open the NDS and hopping on wireless briefly.

The DS doesn't have an open third-party SDK, and no accessible means for running homebrew currently exists. Instead, Nintendo is hoping that Web applications will grant enough functionality to fill the gap. Sound familiar?

Steve Jobs' recent keynote hammered home the insistence that while 3rd party API exposure won't be available for the iPhone, Web applications will be more than enough to offer custom functionality. He suggests that a Web browser can be used in lieu of an ability to launch third-party applications.

The assertion that modern Web applications, what with their asynchronous JavaScript and XML, can replace standard applications is pretty ridiculous. Can JavaScript monitor what roaming tower your SIM card is using? Er... no. Can XML be used to play Doom? No. While you may be able to monitor a RSS mashup, no applications can leverage the hardware in your hand. Saying that any Web application is going to replace a device's native API is hella stupid.

But will the lack of third-party applications hurt the iPhone's success? Not likely. Lack of homebrew availability on the NDS hasn't exactly hurt sales all that much. If you do something and do it well, you're going to sell.

Muted Games N Music

In the time that has passed since I first lamented the DS' limited ability to execute independent applications Nintendo DS development has become increasingly mainstream, and along with that a slew of affordable and easy-to-use NDS flash cards have become available that allows independently developed applications to be executed on the DS. There's even a retail flash card now - the "Games 'n' Music" cartridge. I'm not linking to it... it lacks the file system drivers that make it a useful device. But it's the first flash cartridge (that I know of) that's widely available in retail channels such as your local neighborhood BestBuy.
I picked one up, just to see what it was like. It lacks DLDI support, which means it can't interact with the filesystem. If it can't interact with the filesystem, that means no save games, no loading libraries, no loading maps, no user profiles. Blech.

But it's in retail, which makes it interesting. And it boots DS Linux, which is at least mildly intriguing. At it's cheap... only $35 for the flash card, 128 microSD card and a microSD USB reader. I might waste an equal amount on a craptastic NDS title... so I don't feel too entirely guilty about buying a flash cart that's missing a DLDI.

I think I understand why Datel didn't offer DLDI support. By disabling DLDI people can't execute pirated ROM's from commercial cartridges - instead people are stuck with pure homebrew that doesn't require local storage. This could possibly limit ROM execution of course... but this also wrecks a lot of homebrew.

Thus far I've booted Linux, tried a video and failed to play one homebrew title. Maybe this will eventually gain usefulness once the cart's filesystem is cracked, but until then it may just stay in the bag.

Bluetooth Affinity

Now that I have my handy-dandy Bluetooth phone I'm a regular Bluetooth addict. I've always had an odd engineering respect for the specification (the true measure of a geek is how emotionally attached they can become to a tech spec). Bluetooth seems to have been designed by engineers for engineers, and done very well. The fact that it uses the Hayes Command Set gives me that odd sensation of nostalgia... like seeing a Pac-Man clone on a modern $600 cell phone.

I was pretty impressed with Linux Bluetooth support - a single KDE desktop applet allowed me to browse all Bluetooth devices within range and view their individual services. Within only a few seconds I was able to transfer files and view device status... very schwag.

One thing I didn't understand until now was the concept of Bluetooth "profiles." Just as TCP may be a conduit for HTTP or FTP, Bluetooth is a conduit for OBEX exchanges or headset commands. It makes sense in retrospect, but Bluetooth host devices offer up services such as HSP (headset communication), OPP (pushing files) or BPP (printing).

No OSS project I've run across so far has been able to do vCard or vCal retrieval or transmission. Most projects appear to perform vCard and vCal access via OBEX, which Linux supports. One thing I was hoping to do was send vCards and vCals to and from the phone, but thus far I've been unable to do so. My phone doesn't have the SYNCH profile used for PIM exchange, yet it supposedly transmits raw vCards over Bluetooth... but I haven't been able to get Linux to receive them. Something I can hopefully remedy.

This limitation seems to exist even in commercially available products. DataPilot evidentally supports syncing the phone book, but not the calendar or text messages. Mobile action is evidently C|Net's choice, but just does contacts also.

From what I can tell, my handset supports:

HSP

Headset Profile

Uses Hayes Command Set for headset operations

HFP

Hands-Free Profile

Used for car interop. Synchronous Connection Oriented link with mono, PCM audio

DUN

Dial-up Networking Profile

Networking dial-up abilities using SPP from laptop or other workstation

OPP

Object Push Profile

Transfers are always instigated by the sender (client), not the receiver (server) using the APIs of OBEX operations connect, disconnect, put, get and abort

FTP

File Transfer Profile

Uses OBEX as a transport and is based on GOEP for getting folder listings, changing to different folders, getting files, putting files and deleting files

BPP

Basic Printing Profile

Sends print jobs to printers without needing drivers

A2DP

Advanced Audio Distribution Profile

Possible ALSA integration, used for headphones & media players

AVRCP

Audio/Video Remote Control Profile

Used in concert with A2DP or VDP to allow a single remote control (or other device) to control all of the A/V equipment to which a user has access

Requiescat In Pace

It has been a fantastically horrible month in my real life. I'll just leave it at that. All my current projects, including the portal I was hoping to launch, are pretty much indefinitely on hold.

In other news, I've been trying to find a better way of connecting to my home network while abroad. I've been using SSH to connect and locally forward ports to the home network, but that meant every service had to be hard-coded. Instead I've been evaluating OpenVPN on OpenWRT. Both are amazing projects, and both worthy of considerable attention.

I haven't evaluated OpenWRT in nearly four years now... they had just started using a package manager when I last tried to flash my WRT54Gv2. It's in an amazingly well-adjusted and highly advanced state now... it was hard to believe how flexible the OS & utilities were. Everything worked out of the box with a minimum of hacking. Especially for someone like myself who used to construct Linux home firewalls out of old workstations, this fit my schema perfectly. I was a HyperWRT guy, but as that firmware grew stale I moved an entire distro-in-RAM.

OpenVPN is further evidence of why IPSec tunnels just never gained proper adoption in the roadwarrior market segment. They work fantastic when joining disparate networks through concentrators, but they just don't offer the flexibility, interoperability and ease-of-use that SSL tunnels do. I was an IPSec advocate in the days of FreeS/WAN, but once opportunistic encryption adoption didn't reach ubiquity they supposedly just closed up shop. PPTP offers good interoperability and ease-of-use, but was ultimately PPP with some wrappers around it. OpenVPN has proven itself to be a secure and flexible compromise between the two while still maintaining ease of use behind firewalls, proxies and NAT's. It may lack a certain "purity" of IPSec, but for roadwarrior and ad-hoc connections OpenVPN is indispensable.

Juniper Networks has a pretty good "Instant Virtual Extranet" platform that incorporates an SSL-based VPN solution which does a great job - it even supports Linux. I have to give a big tip o' the hat to Juniper Networks on that one - the actually developed a VPN client that works properly in Linux. Launch a Java Applet, grant it rights to install a client stub on your machine, then an SSL tun0 interface automagically pops up on your Linux box. Bravo.

But I digress.

The NetworkManager GUI within both Gnome and KDE has support for OpenVPN tunnels, so I decided to give it a try. At first I attempted the most simple case using a static key. For the life of me I couldn't get static key support to work with NetworkManager... it wouldn't even establish a connection despite the fact that it worked manually on the console. I gave up on static keys and instead created a public key infrastructure, issuing client keys when needed. This allowed me to establish a connection just fine, but it brought one critical bug to the surface: DNS resolution was subsequently borked, since NetworkManager wiped out resolv.conf once the tunnel was initialized. Fooey.

So instead I created a manual script that initiates the tunnel. That appears to be working pretty well now... no big worries. For now it's a straight UDP tunnel, but I might change it to TCP down the road.

The configuration wasn't too bad - I followed the HOWTO Quickstart pretty much by the letter by creating the keys, issuing them to clients then using their sample server and client config files. On OpenWRT, all I had to do was create an /etc/init.d/S50openvpn script to start OpenVPN on startup, then add the following firewall rules:
### OpenVPN traffic
## -- Permit initial negotiation
iptables -t nat -A prerouting_wan -p udp --dport 1194 -j ACCEPT
iptables -A input_wan -p udp --dport 1194 -j ACCEPT
## -- Permit tun interfaces
iptables -A forwarding_rule -i tun+ -j ACCEPT

Now I'm able to connect and browse at will. Not too shabby!

Amazing that you can build a VPN concentrator, WAP, firewall and management station for a little more than $50. Ultimately you end up with more usability than you could get with a $200 cheapo desktop.

Volunteer Voluntschmeer

I'm so freakin' tired right now.

ConsultComm 4 development is proceeding slower than snot, but what's new. Work is workin' me... like... 45 hours a week, plus I've got family matters to attend to. I'd like to have help development this next version - but whom?

I've tried to get colleagues and friends to help out, but that lasted for less than a week once their interest waned. I put out a job posting on SourceForge and received two responses, but they never e-mailed back. I've tried recruiting, but no luck.

I can't say I blame 'em. Finding volunteers for an open source project sucks. I'm just as guilty as the next guy. I volunteered and did some coding for PlaneShift back in the day, and I loved it. Stayed up late nights in IRC, chatted with the technical architects, worked hard. But in the end I had to quit my day job, find a new one, perform for interviews, etc. The fun development had to go on pause for a while. And when I tried to resume development, the PlaneShift developers weren't really interested in taking me on anymore. Can't say I blame 'em.

I tried to just "donate code" to the Java Desktop Integration Components library, but I was convinced instead to create a new incubator project. I feel guilty from time to time... I just didn't have the time or desire to keep up the project, and it's basically remained dormant since the time I dumped off the source & JavaDocs.

It's tough to donate time and effort. Life sucks up a lot of energy. And often life just plain ol' sucks. When you already donate 10 hours a day to work, 6 hours a day to sleeping, 4 hours a day on family and 2 hours a day on basic upkeep of the house and oneself that leaves... lessee... two whole hours?

Great. One can only wonder why I can't finish anything. The sad thing is, I know all my fellow hackers out there are in the same boat. We're getting old. We're getting jobs. We're getting families. And our internal organs are shutting down. It's hard to have the gusto to be a nighttime hacker extraordinaire.

Sing it with me! "Shiny, happy people holding haaaaaaaaaaaaaaaaaaaaaaands!!!!!!!"

Converge to a Crash

Since the days of calculator watches, convergence of personal electronics was the goal of every gadget-loving geek. Our coffee makers should make eggs and toast. Our watches should be able to convert metric to imperial and give pi to fifteen digits. Our game consoles should be the media hub of our living room. PDA's should be integrated into every electronics device imaginable, but inter-operate with none.

I had a dream called the Samsung i500. Part PalmOS PDA, part phone, sync'd to Linux, allowed third-party applications & Palm gaming. It should have consolidated my iPAQ, cell phone and mobile gaming console into one lil' compact unit.

Hilarity.

The phone was serviceable at first, but it was neither a good PDA or a good phone. Third party apps worked, but space was limited. Sync'ing contacts was a pain because the Linux USB Visor drivers locked up my machine. Things like voice dialing just didn't work. And for some inexplicable reason you could use the phone to receive text messages, just not send text messages. Right.

The i500 had finally taken all the abuse it could and started corrupting my contacts and calendar databases. They eventually got so bad they caused memory exceptions and locked up the phone. Ugly.

During this time I aquired my NDS and an iPod. Calendaring & contacts were actually being served up much better by the iPod than any PDA I had used in the past (thanks to its native vCard and .ics file format support). The NDS was my stop for mobile gaming. And my i500 became nothing more than a half-assed brick.

But this doesn't just deal with the idiocy of smartphones. Look who else is doing this - namely console manufacturers. Sony wanted the PS3 to be your high-def media center, file server, gaming center, music server, bread toaster all-in-one. In the end, however, sales were awful. CNN deemed "the PS3 may be the chrome-trimmed headstone on the grave of convergence." Not to say that you can't have successfuly convergent devices... you definitely can. But you have to do all parts well, not just some. My i500 was a weak PDA and a poor cell phone, but I mistakenly thought that those two weak facets added together would equal a stronger convergent device. Instead I got a broken PDA and a crappy phone.

Same thing with gaming. Cell phone games are popular, but I'd wager dollars to doughnuts the industry has hit its peak. I know that Intel, IBM and Nvidia are ramping up their own system-on-a-chip products for mobile devices, hoping to bring vertex shading to 2" screens. But if you're a gamer, purchasing 4-5 titles a year, what system are you going to rely on? A J2ME-based cell phone that's so tiny the ligaments in your thumb pop, or a pocket-sized DS Lite? Would you rather have a phone that third-party publishers and developers still can't deploy product onto, or would you rather have a handheld console where you can just buy a $30 title off the shelf?

So forget convergence, I'm back to just buying what I need. Now I just need Dockers to bring back their Mobile Pant.

User Supported Public Gaming

The midst of an NPR pledge drive seems as fitting a time as any to talk about how the current "microtransaction" wave that is sweeping the U.S. gaming market is both cheezing people off but also paying people off. Gabe & Tycho discuss how currently downloadable content rips people off in their newest old podcast. Specifically they talk about how EA is offering people the ability to re-purchase the same content they just bought, sitting there dormant on their DVD.

It's just another example of how the U.S. market knows that smaller, content-driven transactions are the wave of the future but, no matter what, they can't shake the idea that people need to pay $60 up-front as well. You can't tax people on both sides of the equation - either pay at the counter or pay at the console. Make up your freakin' mind.

GDC Radio (I love them) had an interview with Joshua Hong, founder of the MMO-ish company K2 Network. There Joshua illustrates how the South Korean market distributes the software for free but then charges for accounts, premium features and in-game items. They've been in the black years with this kind of model, not only because the economics works but also because they grow and nurture a user community. Their primary focus is retention, not acquisition. This is an important distinction... the more a user stays, the more the user pays for content, the more the community grows, the more users jump on, etc.

Linden Labs follows the same model, and it works. Users can join for free. A robust society is nurtured, moderated and encouraged. In-game items and real estate costs cash. And so the circle of life goes.

When you're dealing with something massive and subscription-oriented you can't charge an entry cost. Focus on retention and the rest can follow.

ConsultComm 4 Prototype

I just finished working on the first UI prototype for ConsultComm 4. I'm going to try releasing the pre-alphas as a Java WebStart app - available at http://prdownloads.sourceforge.net/consultcomm/ConsultComm.jnlp .

The JTable/JTree mosh-up is courtesy of SwingX. The code has switched from being very state-driven to being more procedurally driven from events generated by embedded components and JavaBeans. Hopefully this procedurally driven approach will mean less bugs, since actions will only take place at one part of the code. An update to one Bean's property will automatically announce itself to all the other Objects that use said Bean, which means you don't have to force each and every component to maintain the Bean's state.

It's hard to explain. But if you look at the code you'll see a ton of event handlers and action listeners, each of which call a single method. Even small changes make ripples across the codebase, so even distant code can hear when a part of the system has been altered.

I'm not making any sense. To any point, even though the demo is fairly simple there was a lot of work that went into it. And hopefully this work will mean accelerated development afterwards.

DeckerEgo's Razor

I changed the title of this blog from "Tales of an Indy Game Developer" to "Tales of an Indie Developer." Right now my game development has stagnated and may go to zero. But I'm still hacking away on a number of open source projects... as well as hacking the various other constructs I have to live with in my day.

One of the things I'm supposed to do in my paid gigs is architect the infrastructure of entire enterprises. If the title sounds nebulous and nonsensical, it is. Basically I try to coordinate data center sprawl or hack away bits when it gets out of hand.

Through my days I've moved progressively from very myopic fields to extremely broad ones. I started out in LISP working on Chez Scheme, moving to C++ & Motorola 68k assembly, moving to 3D rendering pipelines, moving to enterprise applications, moving to Web applications, moving to corporate networking, moving to corporate infrastructure, moving to enterprise Web application development & infrastructure, now moving to enterprise infrastructure. The uncanny thing is that all of these different genres follows the same Tao of Programming, no matter if it's even really programming anymore.

I'm working on ConsultComm 4 now and it's ridiculously slow-going. I have ripped out every bit of old code and have completely redone things (again), this time trying to follow a more... organic... layout. I'm trying to avoid corner cases and develop things as main-stream to Java's intended architecture as possible. This includes more modern event handling (more akin to Servlet chains or AWT events), better thread management and hopefully a better UI with less "surprises" and non-intuitive user interface choices. This has meant a crapton of prototyping, a lot of refactoring and a lot of brute force hacking. But I'm hoping it will be worthwhile in the end; the goal is to make ConsultComm 4 the last major version.

I've also been spending a lot more time in the debugger. The new codebase is loaded with assert statements meant to catch errors as they happen and plan for unexpected consequences. By doing some deep introspection and catching mental assumptions I make while I code things are error'ing out a ton more, but I'm catching more bugs on the front-end. Also I'm able to catch a lot of one-off circumstances and fail over to more appropriate states.

The same thing applies if you're trying to build a nationwide enterprise-ready datacenter tho. Prototype out the wazoo. Go as mainline as possible - don't try to outsmart existing architecture standards. No surprises. Plain for failure and develop for the exceptions. Document your assertions and watch for when they fail. Introspect and watch all the traffic routing back and forth... catch errors before they become problems.

Ultimately both software and enterprise application infrastructure need to pass the same meta-tests in order to become a lasting solution. You should be able to slice away any piece of the structure and have it remain consistent with the layout of the whole. You wouldn't cut a loaf of wheat bread and somehow end up with a single slice of rye in the middle. However, I'd wager if you went into a typical corporate data center and picked out a random server... heck, even an entire rack... you'd likely find out that it is managed or designed differently than the remainder of the servers in the room. Likewise take an object or source file from a typical software application and you'll find code patterns that appear completely different than the rest of the codebase.

All servers should be managed the same. All racks of servers should be organized the same. All types of servers (DBMS, SAN, storage, application server, development servers, load balancers, firewalls) should be updated, backed up and access controlled in the same way. All objects in an application should follow the same pattern. Exceptions should be handled the same way across all methods. Events, error handling and user prompts should all look and feel the exact same. Refactor like mad if you have to... but if you re-design your pattern, you should re-implement your codebase/servers/data center.

The Tao of Programming said it best:

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity.

A program should follow the `Law of Least Astonishment'. What is this law? It is simply that the program should always respond to the user in the way that astonishes him least.

A program, no matter how complex, should act as a single unit. The program should be directed by the logic within rather than by outward appearances.

If the program fails in these requirements, it will be in a state of disorder and confusion. The only way to correct this is to rewrite the program.

Energy Savings Inaction

First off, let me thank Dubya and the remainder of the inexplicable idiots once again for the passage of the Energy Policy Act of 2005. Not only does this further line the coffers of the oil industry, but it also includes the asinine provision of moving the Daylight Savings time switch up three weeks. Why? Because people will supposedly be awake for more of the daylight hours, so they'll use less lights at home to see.

Let's just take a second to let this stupidity sink in.

Evidently Congress believes they can will the sun to stay out longer during the day. Not only that, but this idea has actually been tried in Australia during the Sydney Olympics. The result? A greater spike in morning electricity usage. Great job.

So not only does this not save energy, it completely screws with every computer in the known freaking world. I've been running ragged trying to patch a number of legacy servers, some to no avail, because they all expect the first week in April to be when DST changes happen. The past two months have been a sleepless blur. Now servers both at home and abroad will be off by an hour. International financial transactions are most likely to be at risk, since foreign DST changes will be different and servers are likely to go unpatched. This may cause enough disruption to make the so-called Y2K bug absolutely minuscule in comparison.

So nice job Bush Administration. Not only do you ignore things that might actually make a difference such as the Kyoto Treaty, but you pass bills that actually harm both the environment, business and industry and then call them "energy policy acts." Brilliant.

Tree on my Table

While I'm deciding on if I should just trash this whole "indy developer" routine I made such a horrible attempt at, I decided to dedicate more time to ConsultComm development.

Desktop integration with Java has been, and continues to be, horrible. It is slowly getting better, but even basic elements are absent or work terribly. The system tray icon works, but isn't any more polished than when it was an incubator project with the JDIC. Now, I'm not trying to be critical of the original System Tray author - he did a fine job. I just expected Sun to make it actually 100% usable.

One thing people have always expected to have was a tree layout for the windowing toolkit with multiple columns for each row. It's not a new concept - TableTrees are in nearly every file browser out there. But for some reason Swing just hasn't had it. Sure, there have been Sun-created articles and tutorials, but no official components. I made one for ConsultComm and have since attempted to make it into a stand-alone component, but it's a good deal of work.

Supposedly the table/tree is making it's way into JSR 296, but those can take a while. I doubt we'll see it soon.

You may notice that I wrote a JDIC component back in the day - SystemInfo. I initially just wanted to donate the code and be done, but was encouraged to make an incubator project out of it. I did so, but quickly became frustrated with Sun's collaboration & project repository Web application and just gave up. Hence the current unusable state the project is in. It appears Sun has now made a separate... something alongside the JDIC mess called "SwingLabs." All the links seem to run in a circle between the JDIC project repository and the SwingLabs site... so I'm not precisely clear on their relationship to each other. But it appears SwingLabs is trying to "productize" or at least "centralize" the disparate desktop components and APIs into a single, coherent package.

In SwingLabs' main package called SwingX they have a new component called JXTreeTable that appears to offer the basic functionality originally put forth in way back in 2003 (probably earlier) with Philip Milne's article. It's fairly basic, but I'm attempting to integrate it into ConsultComm. Relying on a (hopefully) more stable and independent UI codebase should accelerate development. Who knows? I may just fix up SystemInfo if I am able to glean the time. Then again... maybe not. Doing desktop integration via JNI is an insane headache.
