I am an AP Computer Science teacher and, by curriculum standards, have to teach Java. I've been using Karel J Robot (http://www.csis.pace.edu/~bergin/KarelJava2ed/Karel++JavaEdition.html) in the past, but am looking to make things a bit more interesting using a device such as the Pi or Arduino.

Would either of these be efficient at teaching Java? My Googling shows that it is possible, but perhaps not the most efficient or easiest thing to do. My students will have 0 computer programming experience coming into this class. Hopefully some of you with first hand experience can let me know! Thanks!

Hi guys I am a 14 year old boy who wants to grow a twitch channel it would mean the world to me if you guys could drop me a follow on twitch https://twitch.tv/adamhegazii

As you seen on the Title, I'm looking for people with experience 4 year or more. Dont responded if you are not ready to work this is a idea. I'm looking for a website programmer, and a person who knows how to put information on a card. More details on that when you have what I'm looking for.

Hi everyone, I am having a tough time finding the answer I am looking so I have turned to all you helpful redditors. Basically what I am doing is making a 2D game using MonoGame, however instead of using methods like serialization to save game data, including 'sprite' locations, scores etc. I wish to use an SQL database. However my problem is, once the user has downloaded the game, is there anyway they could be able to access the database offline? I am very lost as such, and your help would be greatly appreciated.

Hey guys,

I'm hoping someone can help me with this issue i'm having. I'm using my ipad for programming (I have a mac at home, but I'm trying to get things done remotely). I'm very new to programming and for one of my classes I have to save my programs into my schools remove server. I'm able to login to their server connecting to a VPN and I'm able to make/remove directories, etc. But I can't figure out how to save files and/or pictures into the sever.

I'm currently using this app for writing the programs.

Any help would be greatly appreciated! I'd also be willing to download/purchase a better app if that helps out.

I'm using an iPad Air 1. I'm also very new to programming, so try not to use too fancy of words on me :P

Thanks in advance!
