Question

What the fuck?

dofile("sys/lua/webnet.lua")

w = webnet.new()
e,msg,s = w:load('sys/lua/IpToCountry.csv')

addhook("join","join_hook")
function join_hook(id)
    iso,name = w:lookup(player(id,"ip"))
    msg("©000255000Player "..player(id,"name").." joined from "..name) 
end

LUA ERROR: sys/lua/server.lua:9: attempt to call global 'msg' (a nil value)

The function msg doesn't work anymore?

e,msg,s = w:load('sys/lua/IpToCountry.csv')

The global variable msg is redeclared in this statement and overwrites the existing definition. (Note that even if you declare everything as local, the runtime lookup hash will still bump the old msg with the new one, just rename it something else).

hehe, don't worry, I just took a prelim (midterm) for a CS class and this was our extra credit question:

How do you swap two integer variables X and Y using bitwise operands and no auxiliary variables?

I cannot fucking remember the xor symbol on Java so I wrote in pseudocode:

X = X xor Y; Y = X xor Y; X = X xor Y;

Turns out that you had to write real Java.... T_T FML

^ is the xor operator.

X = X + Y;   Y = X - Y;  X = X - Y;

In a way adding is bitwise AND'ing and XOR'ing :P
