Wow, this is my first entry. I feel enlightened already :)
Well, it is yet another weekend for me without my car. It has been in the shop now for two weeks. Being trapped in my house forces me to concentrate on code even harder.

Today I began working on some skeleton code for a simple filesystem for BSD. Right now it doesn't do much, but there are greater plans afoot! It is not a file storing file system, but rather a proc style file system concept.
A month or so ago I wrote a quick and dirty language that had a pretty impressive symbol table system. my hopes and dreams are to integrate that language with this filesystem. essentially what this would give you is a programming environment which could be debugged and or interacted with from an outside process via a simple file system interface. Imagine this senario:

The Following lines of code could be executed by the mangle interpreter (The little language I mentioned earlier).

def string mystring; mystring="Hello World!";

Now, at the same time, a seperate process inspects the programs symbol table via the file system:

# cd /mangle/$MANGLE_PID/symboltable/ # ls mystring # cat mystring Hello World! # echo "Smello World" > mystring # cat mystring Smello World #

Now, returning back to the mangle interpreter, the session continues without a burp:

print mystring; #the program prints out "Smello World" undef mystring; def number foo; def ref bar; foo = 5; bar -> foo;

Now back to the file system, we see the new changes:

# ls -l /mangle/$MANGLE_PID/symboltable/ rw-r---- root wheel foo rw-r---- root wheel bar # cat foo 5 # cat bar ->foo #

This is how pathetic I am, I really have nothing better to do with my time. I actually love this stuff. Needless to say, I am still single.
