Windows Phone as "notification screen"

I recently bought a low-end windows phone from a coworker for $10, not really having any particular plan for it, but thinking I might be able to do something cool with it. Well, for the past couple weeks, it's just been sitting on my desk collecting dust.

Until a couple days ago, I decided I wanted to try to use it as a sort of 3rd screen at work, where notifications could be shown. I've got a few things (pidgin chat windows, emails, linux desktop notifications) that I want to be aware of, but I sometimes miss. My icon for pidgin changes color when I have a new message, but sometimes it's a hassle to pop it up to the top if it's not important (and it's hard to know if it's important without seeing it!) Thunderbird shows a desktop notification on new email arrival, but that only lasts for a couple seconds; I often miss it, and then I have to go click on it to see if there's mail.  1st world problems, yes. And I'm not sure I really need to fix them. But really, I have a solution (this phone) in search of a problem, so I decided to play with it!

Catching thunderbird messages was the easy part -- there's a great thunderbird extension (Unread Count) that automatically generates a text file that contains information about how many unread messages you have in each mailbox.

For desktop notifications, I did some reading, and it looks like I needed to hook into DBus, linux's inter-process communication channel. Reading through tutorials about how to hook into it, it looked like somewhat of a hassle. So I took the easy route, and used the dbus-monitor command, which generates a text stream of all the information flowing through dbus, and piped it through a python script that just looked for libnotify notifications, and wrote the details I was interested in to a separate file.

While playing with dbus, I noticed that all pidgin messages traveled through it as well, which made it really easy to catch the sender name and text content of the latest message, and write it to a file as well.

Then I have a simple php web script that pulls the info from all these files, and builds a not-too-ugly notification page out of it.

I originally planned to just point the phone's browser to it, and have a meta-refresh on the page, but the windows phone browser kept the status/url bar open the whole time, which was ugly and wasted space. So I ended up writing a windows phone app that was merely a wrapper over a webView that reloaded the page repeatedly. Moving the refresh logic to the phone app also allows for it to keep refreshing even if the web server temporarily dies, which is handy.

So here's the finished product. Who knows if I'll actually ever look at it, or find it remotely useful. That's not really the point here, is it?





Side note: currently I have a private git repo on bitbucket where I keep all my misc rinky-dink projects. Maybe I should just make it public instead, so things like this are available to anyone that wants to look at them. I'll have to think about that. (It would mean I'd be more afraid of my hackish little quick code being judged as terrible, so I'd be nervous about throwing stuff on there willy-nilly)

Retrospex 32 Review

RetrospexInternational recently sent me a couple units of their new handheld device, the Retrospex 32, a new dedicated GameboyAdvance emulator handheld.  To make the unit playable out of the box, they pre-loaded a handful of homebrew games, including Anguna, which is why they were kind enough to send me 2 of the units to play with.  I was pretty excited to get my hands on the device and try it (I loved my old GBA micro with a good flash cart!), and see Anguna running on it. So here's my thoughts after playing with it.



Their website lists the Retrospex 32 for £59.99, which is around $100 USD. It seems like it's marketed toward people into retro-gaming (which makes sense for a dedicated GBA emulator device). At that price, with that target market, and such a limited set of functionality (why not make it a multi-machine emulator, and emulate all the old consoles?), it would hopefully do a really good job of it.

The short version of my review: it doesn't. It has one job (emula…

Making the game fun

The real trick for Spacey McRacey (as I'm calling it now) is going to be making it fun.  And that's what I'm rather unsure about at this point.

I have a game design that basically works. The technical issues are mostly sorted out, I just need to get a few more implemented before I can seriously play test it.

But fun? It's hard to know if it's actually going to be any fun to play.  With a 4-player party-style game, it's seems like it might be hard to hit that fine line where everyone is close and competing, where everything feels exciting and tense, as opposed to tedious and boring.  And despite envisioning my game as fun, it might just be boring to play.

Some of that comes down to tweaking it. Tweaking the speeds, difficulties, etc, will make a difference. (If it's too easy to shoot people from behind, then it will be nearly impossible to hold a lead for very long, which could ruin it and make it no fun. If it's too hard to kill the guy in front, it wil…

Killer Queen

So at PRGE, I played an arcade game that just left me amazed.  Killer Queen.

It's a 10-player game. You have 2 cabinets linked together, and 5 players huddled on each one. Each one is a team of 5 people, working together to play a simple one-screen 2d platformer.  But what made it work was the high quality game design.

First, the game is relatively simple, yet there is a lot going on at once.  One player plays the queen, the most important and powerful character on the team. The others start as workers, but can become warriors who can fly around and attack in a very joust-like flappy contest of height.  The real trick is that there are three completely different ways to win: either collect a bunch of berries and bring them back to your base, or ride a REALLY SLOW snail across the screen (while other people try to kill you, and you hope your team protects you), or kill the enemy queen 3 times.  There's some other things going on as well (using berries to upgrade, capturing upgr…
