I would say most of the waiting comes from ACK. Also the fact that the packets generally have a large (comparatively-speaking) header that needs to be parsed out before any real information is actually given. Processing power/wait time is larger compared to UDP. I'd still use UDP for things that require a lot of packets and don't matter if something happens to them.

UDP stands for User Datagram Protocol.

And I have no idea how that AppWarp thing could possibly achieve high performance real-time data transmission in Flash Player; that seems rather dubious to me. I tried finding out how it actually works on their website, but they offer no explanation, at least not that I could find, and it's not open source.

Honestly it might just be as simple as "it's just that fast"
When I use a loopback with AS3 clients and servers, data transmission is pretty damn quick. Much quicker than what they showed, actually.

I found the git link, but there's just a swc :(

When I bother NG servers to give me save file info or whatever, is that tcp or udp or neither? What's the preferred way of doing multiplayer in general?

That would be TCP.

I wouldn't say there's any preferred way of implementing mutliplayer in general; all depends on what it is you're doing. If you're making a real-time multiplayer game, such as pretty much any MMO, or shooters like Team Fortress 2, then you'll want to use UDP. If it's something that is turn-based, like a game of chess, or a chat system, you would want to use TCP (especially so if you're making a chat application).

Basically if you need to guarantee that your data will arrive, like you would with chess or chatting, you want TCP. If you don't need a guarantee of the data's arrival, and just want to send/receive the most up-to-date information, such as in MMOs, or VoIP programs, you want UDP.

Thanks for the docs and help Diki, it's a drag that FP doesn't support UDP but I can do without it I guess.

Second day of uni and we're going to be getting into networking in a couple of hours. Had to make a Cisco student account and read through a whole load of crap I think has nothing to do with the subject.

That's definitely way better than a 3 hour tutorial talking about rollover and straight cables. It took 2 whole hours to plugin and setup a router and a switch with this Cisco terminal crap. Just punching in a list of ipv6 install, ipconfig /all, enable commands blindly from a textbook and not understanding anything the terminal spits out is what the first tut consisted of.

Man this thing kills me, who knew a router would be this complicated to setup. So rollover is for config, crossover is for devices with the same port and straight through is for connecting to the router?
Some clarification would be awesome since I didn't even bother listening in class especially the difference between crossover and straight throughs.

Those are the two most common!
Omitting a bunch of stuff and oversimplifying for clarity:
Crossover is client to client (computer to computer)
Straight-through is client to server (PC to router, router to network)
Rollover is because fuck you that's why

That's because of ECMAScript's retarded way of handling numbers and strings. It's just converting the integers to strings when used in that context, which is the same reason crap like this happens:

var data:Array = [1, 2, 10];
data.sort();
trace(data); // [1, 10, 2]

Yes, since that's what the ECMAScript spec says should happen. As for ActionScript being able to determine that the given key was originally an integer that's just a goofy special-case scenario that was included for whatever reason; if you use any other type, such as Number or a class with a toString() method, the key will be considered a String. Either way that behaviour is not part of ECMAScript, as you can see with this JavaScript code.

I've been having a lot of issues with haxe/openfl in FD lately. It doesn't connect to the debugger during flash export, there's always some error with a plugin that doesn't check if the project is in as3 or haxe, and code completion never works. Anyone have a working workflow with it? I'm on one of the latest nightlies, but the main release had worse problems.

So a couple days ago (in class) we were assigned topics for our persuasive speeches. We got to semi-choose ours, I chose the one that said "security and encryption" because that kinda sounded like my thing.

Turns out, I'm now supposed to make a six-minute speech (with data backing it up) persuading people that encryption is not only a viable replacement to login systems and firewalls (yes, login systems and firewalls specifically) but that it should ALWAYS be used in place of those.

Soo... Does anyone know anywhere I can find good supporting arguments for this? Because I'll be damned if I know where to start looking for this particular rabbit hole.

A firewall analyzes and blocks packets, a login system validates login information; I don't see how encryption on it's own can replace either of these things.
Are you sure it's not about the importance of using encryption in conjunction with login systems / firewalls?

I use Sublime text 2, it has a plugin for haxe/openfl, allows you to select target platform, jumps to compilation errors and has decent code completion (the build-in code completion from Haxe). I've got nothing to complain about. The only thing that is a major pain in the ass is combining haxe/flash and the debugger; but that's not related to Sublime text 2.

A plugin had an update available, and it seems like that fixed everything (it wasn't checking the current project type, so it was doing as3 things to a hxproj). So now my issue is trying to get it to connect to the flash debugger and trying to understand @psvils' entity system.

That's exactly what I said to the teacher, and yes I'm supposed to persuade people to always use encryption in place of these two.
Thankfully the people I'm persuading don't know much about computers at all, so it should help. I might be able to get away with incorrect facts and some made-up crap thrown in.

I could understand if they wanted you to try and argue a difficult point - and provide some insight as to why it's not valid. But to argue that it should always be used it a strange one.
