    There are 2 methods:
    WebOS Quick Install: How to: Homebrew Apps, Patches, and Themes
    Preware: Application:Preware - WebOS Internals

    I don't know what OS you're running. You should ensure that the patch is compatible with whatever OS you're using.
    thanks !

    No lol. Not sure what I was thinking. It was intended for my themes and I thought it would be great to add to my sig however, I didn't think about the fact it would show across all of my new posts. I am removing it since I ended up adding it to the theme posts solo.

    Well, you could have a link to your themes as well as the donate link in your sig....just a thought.

    One thing that you are to be congratulated on is being the only application in the App Catalog to not go with the 99 cents garbage and made it $3.00 not $2.99.

    Oh yes, that's a reason to buy it!

    Wait I have to measure the temperature of my drink first, then measure the temperature of my fridge, then input that information into your $3.00 app and it'll tell me how long till my drink is at the perfect temperature? Why don't I just let time decide how long it'll take and wait it out? I'm sorry but apps that require me to do all this work aren't really apps but more time wasters.

    This is just a Newton's Law of Cooling calculator?

    well at least he developed something for all you people so quick to be critical and all. if he wants to sale more he will drop the price if not its his own choice leave him be and develop something for yourself lol

    I think that doing scientific experiments is not a waste of time. open your mind a little ...

    Newton's Law of Cooling calculator?
    It's more complicated than you think. We must put the time parameter in the equations, and heat transfers and the shape of the bottle. At end, it's a differential equation


    Updates coming soon...
    Version 0.8.1 : time to wait to make ice cubes !
    Version 0.8.2 : how many ice cubes should I put in a drink ?!

    I think everyone in this thread will be interested ...

    thank you ! you should be encouraging developers, not making fun of them

    Newtons law of cooling _is_ a differential equation with respect to the time

    New version available published in the next app catalog update ; version 0.8.1

    Coool Drinks Calculates how long different drinks take to cool off and how much time it takes to make ice cubes, in the fridge

    soon Available in app catalog for $1.49 (new price)

    A lot of new features will be added !

    Am I right now with the differential equation?

    LOL, after this he goes and changes it to $1.49 (not $1.50)

    No offense to the developer intended, but I have a hard time seeing a buck and a half for this, when I've been cooling my drinks ok for nigh on 50 years. I think it's great that you created something so that you could learn WebOS programming. I'm not so sure I'd expect people to pay you while you learn. But that's each individual's choice.

    On a more general note, it strikes me that a great many of the apps in the catalog were created simply because someone could, and the tools make it easy, not because they answer a real need. This is the flip side of development tools that almost anyone can use: apps that almost no one needs.

    I'm out of my mind. But feel free to leave a message.

    it's something like this :

    m*c*(Tfinal-Tinitial) = P*delta(t)

    P depends on the shape, the volume and the total area of the bottle. It also depends on the bottle material and thickness and all the side don't exchange heat the same way. At the back of the bottle, it's heat conduction between two solids, while it's between solid and (O2+N2) for other sides.
