No, just one on one for now. I was thinking of adding an option to pull in another random stranger, but that'll have to wait til tonite/tomorrow if I have the time.
Hi, author here. I made this site as and alternative to Omegle, correct. I was interested in finding some way of meeting new people and making connections, which seems to getting even more difficult in this short attention span, information overloaded world. So far, as an experiment, it's worked for me and a lot of interesting users have come online and I've had some really great conversations. If you have any questions about the site's motivation, just ask.
Oh, and I made it in node and jquery and about 2 hours.
I'm not quite sure how being able to extend syntax is a theoretical problem. It was just a basic example for brevity.
There are many more examples of macros that solve real world problems, such as writing a compiler for an embedded DSL that is tuned to solving your real problem that allows expressivity and brevity that you would never see without the use of macros.
A lisp macro is a code transformer run by the compiler using the full features of the language to generate code.
Macros allow for the arbitrary evaulation of it's arguments (rather than the standard left to right order before a function call), allowing you to do syntactic extensions without the added boilerplate that functional languages can require.
Essentially, each macro allows you to define a mini-language that is parsed by the compiler that returns code that is then compiled. It takes a while to groc, but once you do you can never really go back.
The title reminds me of a book I used to have years ago called 'Writing Bug Free C Code for Windows'. It was a great and not windows specific all all, covering object systems and all the nooks and crannies of the language. It was on par with some of the Lisp books I have regarding coverage of language features. Highly recommended for those interested in what you can do with C, but I'm sure it's impossible to find these days.
Thanks for the info. I've done some research on competitors and I'm trying to find the correct pricing vs my costs for the system. This is my first web service so I'm really just trying to figure out all the details on something simple that I haven't seen provided yet and go from there. Hopefully some people will find it useful, but I realize I have to keep my pricing in check but my costs in balance.
