Did you know that you can program and run Python on nearly any Android smartphone?
You can literally whip out your phone and start programming on the run -- it's like a calculator on steroids! (although support for graphics is nearly nonexistant, as far as I can tell, so games are out)

You can also do Lua, Perl, jRuby, and a few other languages, I think.

This is so awesome: I just had to share.

Yeah, Linux is awesome.

I really need to install a Linux distribution someday.

If someone could wrap the core Android GUI libraries with Python, it could work

Well yeah, since Android is some sort of Linux distro, you can pretty much do anything with it.

Nice. I'm gonna have to look at that.
I did manage to setup a rudimentary Java programming environment on my Droid, through the use of an online IDE and an online compiler. Link that with my Dropbox, and I think it works quite nicely.

Python? Me too thought it was Java only. They're introducing Flash on 3.2.

Other calcs, laptops The pandora. Netbooks too, but I guess they're laptops

@tloz "on top of" means it runs on linux. Same thing as saying Fedora runs on Linux, or Ubuntu. They just made a Java-centered Linux OS.

So far nothing beats the calculator for programming on the go I guess. Laptops are great but not as portable (you can't take them everywhere like calculators), but the TI calculators are amazingly well designed, the buttons are so easy to get used to yet it looks complicated, I love it. It's looks like what a real professional programmer would use on the go, I think people also look smarter / nerdier while they're using it. If they had cell phone capability, web browsing capabilities, able to take pictures and videos, were in color, and you could program in more than just TI-Basic, it would be the best thing ever made (in my opinion).

Maybe it will be made in the future, something like "The Pandora," it would be the size of 2 TI-83s held sideways (like a ds) and you can open it up to reveal a full sized screen as big as a ti-83 and a keyboard as big as a ti-83. It wouldn't have a QWERTY keyboard though because that would take up too much important button space. you would have to alpha-lock just like in the TI calculators to use it, but it would be in QWERTY to make it easier. There would be two analog arrow keys for games (I guess like "The Pandora" except it would be normally hidden under regularly used buttons, and you can flip it from beneath some buttons when you're playing games, and it'll have other buttons under than flip too).

Sounds cool right? I want to make this someday, when I'm in college (I'm gonna start during the summer right before my Sophomore year). In the meantime, I'm going to master learning how to program in PHP, java, axe and ruby (C++ too?) first. I think I'm dreaming too much, but I still think it's possible. I'm just not knowledgeable enough at the moment, I don't feel ready to make something like this, this very second. We'll see what happens 3 years into the future, hopefully the world doesn't end next year though, but then again, a lot of people are going to throw parties... and you know, can't wait for that either...
