LuaSocket: Network support for the Lua language. What is LuaSocket?
LuaSocket is a Lua extension library that is composed by two parts: a C core that provides support for the TCP and UDP transport layers, and a set of Lua modules that add support for functionality commonly needed by applications that deal with the Internet. The core support has been implemented so that it is both efficient and simple to use. It is available to any Lua application once it has been properly initialized by the interpreter in use.

How to bypass strict firewalls on public wifi hotspots and restr. Public wifi hotspots and restricted internet access More and more, you can find public wireless hotspots, in cities, train stations, airports... and even some public hotspots that are available with a subscription, accessible through a web login form.
The thing is, most of the time, these hospots will have a reduced connectivity. Upside-Down-Ternet. My neighbours are stealing my wireless internet access.
I could encrypt it or alternately I could have fun. I'm starting here by splitting the network into two parts, the trusted half and the untrusted half. Is your firewall spying on you? IT'S OBVIOUS, REALLY, that the best way of penetrating users' PCs to see what they get up to online would be to become a Firewall maker.
Like, when I wanted a Firewall and was too tight to pay for one, I turned to Checkpoint's little freebie Zone Alarm. It sits there between you and the Internet and lets you know when someone's trying to sneak in through your backdoor or when a program you're running tries to connect to the Web for no apparent reason.
When you're as techie as me - not very - you just have to trust it. Of course, Checkpoint's an Israeli company and as a foreign journalist working in Israel you know the hyperactive security services here would like to keep tabs on you. And you know that they do. S Guide. Beej's Guide to Unix Interprocess Communication Now that you have extra-process communication going on with sockets, why not try your hand at some interprocess communication, eh?
Shared memory, semaphores, signals, and memory mapped files await you! Beej's Guide to C [rough draft] This is a bit of a practice book for later when I write a real book. Since I know C more like the back of my hand than any other language, it's a good place to start (because I don't need many references to write it!) Keep in mind that this is completely incomplete right now, and I haven't even read most of what I've written. Some of it is Just Plain Wrong.
