Using Mpowerplayer to demo Java ME (J2ME) apps online

Do you write Java ME applications? Want to display the results of your work to visitors like that fancy emulator that comes with Mobile.Processing. Well, Michael Powers (developer of the great MPowerplayer MIDP 2.0 SDK for OS X) has developed a free web emulator you can use in your site. Here’s how in three easy steps:

1. Upload your application’s .JAD and .JAR files to a directory on your website. Make sure you set the MIDlet-Jar-URL property in the JAD file to the full URL of where your JAR file will live. I put mine in http://uberthings.com/mobile/code/1/, so mine looks like this: MIDlet-Jar-URL: http://uberthings.com/mobile/code/1/AwesomeMIDlet.jar.

2. Create a page or a hyperlink which links to your JAD file like the one above.

3. Change your hyperlink to point to the MPowerplayer Demo player by removing the http://, adding http://webstart.mpowerplayer.com/, and appending .jnlp to the end. So my link above now looks something like this:

http://webstart.mpowerplayer.com/uberthings.com/mobile/code/1/AwesomeMIDlet.jad.jnlp

Click here to see it in action.

Bam! You’re done.

Chumby Devices Handed Out at Foo

Michael Arrington from Techcrunch writes about an interesting new hackfriendly mobile device called the Chumby.
Chumby Devices were handed out at Foo Camp to about 100 lucky Foos (I’m looking at you, Raffel) to prod, poke, develop world changing applications and generally hack to pieces. I’m not going reprint the technical specs verbatim, but the most interesting thing for me is the input methods – touchscreen or squeeze sensors on the casing let you interact directly with this guy, no buttons, keys or mice to get in the way.

Practically nipping at the heels of Synaptics touch screen cell phone prototype announcement, it definitely feels like there will be a fair amount of mobile/portable devices with gestural control interfaces in the near future. Now if only Synaptics would hand out some of those cell phones for student projects…

Starcraft Origami

Zerg Origami (so cute!)OMG. If you’ve ever spent hours building up your puny Terrans and mighty Protoss forces to withstand a Zerg rush – you know what I’m talking about. Here are those same terrifying pixels, gently shaped and folded to look something like this – 야후! 이미지박스. I should have guessed that it was a Korean who did it, it seems like everybody mainlines the stuff over there. If you ever get the chance, try to watch Starcraft TV. Who says video game spectating is boring? It goes a little something like this.
