I had an idea: to use HTTP api, PHP, and Objective-C to make an OS. I have the messages working - the computer detecting input, sending it to a web server, and my Objective-C program picking it up.

Here's the output(on the Xcode debugger) I get from doing the following
leftclick
rightclick
"a" key
"b" key
"c" key
scroll up
scroll up
scroll down
scroll down
scroll down
drag(leftclick)
drag(leftclick)
drag(rightclick)
drag(rightclick)
drag(rightclick)
rightclick
rightclick
insert floppy disk on left side
remove floppy disk on left side:

I'm still working on the actual handling and returns, but what do you think of the concept? I'm also looking for someone else to work with on the project, so if you're interested then please PM me.

Here's the implementation code, if you want it:

So you are trying to make online OS, and only the client for it will be on the local PC?

That's the basic idea.

In the long run, I'll be using a server-side database to handle, sort, and identify all incoming posts, and do similar IDing with objc. The plan is subject to change, of course, I don't know exactly where this will lead to.

I might have multiple instances running and distribute the data equally to reduce load, if it comes to it(which is completely ridiculous anyways)

One idea is to use a login system since multiple users may be using it at the same time and you want to be able to differentiate them.

What i internet is down for whatever reason, will the client then handle the events itself? If that is done as "back-up" system, why would you connect to the internet to handle events in the first place? What is the point I am not getting?

No, I think the OS will be programmed in C. No backup in Lua...

Oh pretty please, you dont get it do you?
If your internet shuts down for any reason, goodluck with this OS, because it is not going to work out....
Frankly, unless there is some backup mechanism, this seems pointless really. Its cool to program in a programming language you prefer over Lua, but the downside is that everything is going to be sent to a server which executes and then a response comes back. The concept is cool, but practically I think bad...

On a side note: learn*

Yes, if my Internet or the client side Internet is down, then it won't work. Keep in mind that his is a concept, and the main reason I'm making it is for personal satisfaction. Besides, people have Internet most of the time.

Like I have said previously it is a cool concept, but practically it is not usefull. Making an assumption like: people have Internet most of the tie is technically a bad thing to do because we, as programmers, should consider every possibility IF we want to support that.

I want to encourage you to continue anyway, because it is for your satisfaction plus then it is proved we can program in other programming languages. If you consider me as someone who is against this project, I am not. Do what you want to do and whenever you like. I am just giving my feedback as a friendly guy, if anything came out wrong, then I will apologise for that.

No no, thanks for reminding me about people without Internet. I will probably add some kind d backup or maybe single player support for a local client(with LAN)

This I can't see working or even being slightly useful... Imagine the response time for running calls to the computer... anyway:

I do not get why you don't just use C? :s Considering Lua compiles cleanly as C? You could easily fix the bits and bobs and make it work client side?

He's got a point about response times. That may really be bothering. What I thought about was to use it as an external storage. For example, I have 100Mb of space on your system. I can then upload files and use them directly from computercraft.

I have started a script for this xD, allows you to run virtual commands and use storage, like a http based rednet file browser / nsh kinda thing :P

Should I make an FTP type program? Would you actually use it?:D I had a small test one made but never actually released it?:P Should I?::DDD

The response time is definitely a potential problem. ATM it isn't too bad, but I'll work out a solution if it comes to that.

One possibility is to send the user input info directly to the program, but with my server setup that would be a pain.
