    Jailbreaking iphones

    I posted this a few days ago, evidently it go lost in the db shuffle.

    Anyway, someone gave me an iphone 3G to play with and I am thinking of "jailbreaking it" with redsnOw so I can install Cydia stuff like bash and perl. Then instead of playing pong on the bus I can brush up on my shell scripting.

    Has anyone done this? Any caveats?

    Just that you void your warranty when you do it and Apple hates you when you do it. Nevertheless, from what I am told, you can just undo the breaking and no one will know.

    Finally got around to this last night and of course, ended up with a wrecked phone which took me hours of wading thru internet posts to fix, lost all the user data on it. And the warranty is probably very very void, lol.

    Redsnow on my MS laptop was a complete disaster, but I think that is the standard for this stuff. "iREB"'s dysfunctionality made me cringe. Redsnow on OS X seemed much much better. Probably if you actually make regular use of these devices and the respective OS's it'd be easier.

    Re-enforced my loathing for the proprietary OS's because of their intense user unfriendliness. They are just horrible awful things to have to use. Not fighting words, just a very honest feeling. Completely hate it. On top of the clumsyness, the restrictions and paranoia are TOTALLY INSANE. I cannot believe people pay for this tish.

    Anyway, I do now have the phone mounted "ifuse --root"

    OMG! Is that the world's greatest file browser running in a terminal emulator on iOS 4.2.1??? Yes, in fact it is!! Right along with bash! And -- as if that weren't enough to get you a date in an elevator already -- VIM.

    Wow, why the blur? If that's your porn collection, I'd like to see the titles.

    Probably a mobile phone camera, or a very poor digital camera.

    What are those yellowish circles on the left? Does it say Lego?

    Here's something I did almost thirty years ago:

    As in, the pic is from 30 years ago or you never took it apart, lol? My dad's Danish -- and a mechanical engineer -- I always had a lot of Lego. I would build 2-3' battlecruisers with helicopters on them and stuff.

    I recently moved back near my hometown and my sis has some of the old blocks for her kids, so after showing them a few tricks I palmed a couple pieces

    The picture is 5-6 years old and the GoCart is still alive. The sole survivor of my Lego collection.

    You stole from your little nephews. Man, that is so cool! :

    And BTW, I've been using the Lego car picture above as I was developing my iPhone slider game. My designer replaced it with his own images for the final version, of course. I didn't complain too much as maybe we could have had copyright problems with Lego or whatever.

    So the game went live on iTunes today. It's one of the zillion slider puzzle games on iTunes but it has few things that make it a bit different. You can add your own images with camera or from the Photo Album and you can play over WiFi or Bluetooth with someone else. You can play against others, or in Assist mode a parent and kid can solve the game together, each on his own device.

    I don't think many people here have iPhones, but if anyone cares about such game, here are a few promo codes so you can have it for free:

    PPPTNXPWPH4F

    Hope someone might like it.

    Yeah, that's pretty cool (thanks). I'm kind of obsessed with figuring out some kind of system now after getting times ranging from 15 seconds to 15 minutes, lol.

    So is that written in objective C? What's the graphics API you used?

    I'm glad you like it.

    I've played this game thousand times in every phase of its development and I sometimes lose 30 seconds or more just to swap two tiles. Then, next time I solve the whole game in 15 seconds. There's no justice in this world.

    So is that written in objective C? What's the graphics API you used?
    Objective C, yes. Three years ago I was sure this is the ugliest language on the planet. Now I love it. Graphics is mainly just UIKit objects containing PNG images. Some transparency here and there, some scaling and rotations done with CoreGraphics. That badge with the number at the bottom is an oval rect with barely visible white background just to make it glow a bit.

    The only thing related to graphics that was more challenging was rotating and scaling images in the background. UIKit has methods for that, but they were not thread safe, so I had to go low level with CoreGraphics. So the thole application is actually an exercise in NSOperation (used for background threads) that rotates, scales and slices images and stores results in SQLite database.

    Then I discovered networking, Bonjour, GameKit (for Bluetooth communication) and put it all in a single game. I had all of this last November, but then it took six months for someone to design backgrounds and all PNG images for buttons. I worked with three guys. People say we programers are hard people to deal with, but designers,... well, they are definitely worse.

    The thing is, I am working on several other projects that build on top of these technologies and I hope I'll have at least one really cool application this summer or fall (or next May at the latest).
