This is a simple prototype that I've made to explore the power of non-blocking sockets.
I've tested it with a thousand connections and it should handle some more.
This can be used for a multiplayer flash game or a community chat, but since it isn't "production ready", use it at your own risk
It can be also useful to who want to implement his own server.

Features:

• >=1000 connections
• anonymous nick, free nick (free to choose you own) and registered nick with mysql/postgre/sqlite/dbo compatible
• Can run in some web hosts like Dreamhost Update: It violates their policy

To run:

Here are also a bunch of AS classes to interact with the server and an example application like the "mouse chat" in my website. Update: my hosting (Dreamhost) doesn't allow FlashServe, the party is over
Sadly, since these was made 4 years ago with an italian friend, all the comments are in italian, if someone is interested, I can translate it.

You can use my server at dev.madarco.net:7777 but only in the Flash IDE (no crossdomain.xml)

The main features are the simplicity and that it help to stay in the schedule.

Using Plick is simple:
just specify a task and the time you think will be required to do that (eg: "clean room 15" = clean the room in 15 minutes)
then, when you are doing that, just click on it and the timer will start.
Plick will keep track of the time spent on each task, in this way you can see if you spent much time than you expected, helping you to make better previsions.

Ok, the exams are gone, and I'm ready to came back to my projects!

Finally, I've (almost) completed a reference explorer for flash: this application show the object tree in a swf, it can be useful while debugging and it can help find circular references:
in Flash up to 7 circular references doesn't allow objects to be deallocated by the garbage collector. A nice explanation of the problem can be found in this Grant Skinner's blog entry.

Although this issue doesn't exist for the new Flash 8 garbage collector, it is still present in Flash Lite 2.x.
A reference explorer can also help refactoring or be useful to visually debug your flash projects and to explore object dependencies, in future I could extend it to show information useful for debugging like object variables and class hierarchies.

Usage:

• Download it and click on main.html
• Type the name of the swf you want to load, you can see the movie in a window
• When you are ready click "Analyze" to show the object diagram
• Red objects contain a circular reference, the name of the variable holding that reference is showed in a box
• After each object name you can see the class name

Try it online with a test swf: (or your own if you set proper cross domain policies)
