[2009/02/05 12:32] Snowdrop Short: lol
[2009/02/05 12:32] Snowdrop Short: the homework assignment was to
download and install
[2009/02/05 12:33] Snowdrop Short: either Visual Studio C# express or
mono-develop
[2009/02/05 12:33] Snowdrop Short: depending on your choice of
operating system
[2009/02/05 12:33] Snowdrop Short: having done that will make things
easier
[2009/02/05 12:33] paulie Flomar: Oh. Sorry. I'll just listen,
then. :)
[2009/02/05 12:33] Alyvaral Aeghin: ok, I'll wing it ;p
[2009/02/05 12:34] Snowdrop Short: also that way you'll have the
opportunity to experiment a little
[2009/02/05 12:34] Snowdrop Short: I've been thinking about how to go
about this
[2009/02/05 12:34] Snowdrop Short: and decided that the best would be
to jump right into it
[2009/02/05 12:34] Snowdrop Short: is that ok with you?
[2009/02/05 12:35] Jeff 1564: 100%
[2009/02/05 12:35] Adelle Fitzgerald: yep :)
[2009/02/05 12:35] Snowdrop Short: from now on I'll just say IDE
[2009/02/05 12:35] Snowdrop Short: that's short for "Integrated
Development Environment"
[2009/02/05 12:35] Snowdrop Short: so that's either VS C# Express or
Mono-develop
[2009/02/05 12:36] Snowdrop Short: depending on what you have got
[2009/02/05 12:36] Snowdrop Short: if you haven't started your IDE, I
think you should
[2009/02/05 12:36] Snowdrop Short: let me know when you are ready
[2009/02/05 12:36] Adelle Fitzgerald: ready
[2009/02/05 12:36] Jeff 1564: here too

keeping updated via IRC
[2009/02/05 12:37] Snowdrop Short: my computer may be a little slow
[2009/02/05 12:37] Snowdrop Short: I'm running quite a lot of
programs on it
[2009/02/05 12:38] paulie Flomar: Always happens just when ya
needit. :)
[2009/02/05 12:39] Adelle Fitzgerald: I thought this class was to
start at 21:00?
[2009/02/05 12:39] Adelle Fitzgerald: thats why I was late
[2009/02/05 12:39] Snowdrop Short: I thought so too
[2009/02/05 12:39] Snowdrop Short: but then I saw all the people and
thought I might have made a mistake
[2009/02/05 12:40] Snowdrop Short: I'll just do it twice to make up
for it :-)

[2009/02/05 12:58] Adelle Fitzgerald: oops
[2009/02/05 12:58] Starky Rubble: its fully permed and set to a buck
lol
[2009/02/05 12:58] Snowdrop Short: I think it might be because I set
the notecards to no mod
[2009/02/05 12:58] Snowdrop Short: maybe that's it
[2009/02/05 12:58] Jeff 1564: i will go to a sandbox and brb
[2009/02/05 12:59] Snowdrop Short: that way people won't accidentally
delete the sample programs
[2009/02/05 13:00] Snowdrop Short: I gave jeff 5 notecards
[2009/02/05 13:00] Snowdrop Short: actually I have 6, but the last
one is meant to be a bit of a surprise
[2009/02/05 13:00] Snowdrop Short: so I'll hang on to it for a little
while
[2009/02/05 13:00] Snowdrop Short: did anybody see the video I gave
you a link to last time?
[2009/02/05 13:01] Adelle Fitzgerald: the beginners thing?
[2009/02/05 13:01] Snowdrop Short: yes
[2009/02/05 13:01] Adelle Fitzgerald: yep :)
[2009/02/05 13:01] paulie Flomar: no
[2009/02/05 13:01] robert omegamu: yep watched it aswell
[2009/02/05 13:01] Adelle Fitzgerald: i even did that same app as on

[2009/02/05 13:01] Snowdrop Short: what did you think, was it any
good?
[2009/02/05 13:01] Adelle Fitzgerald: and published it
[2009/02/05 13:01] Adelle Fitzgerald: and installed and ran it hehe
[2009/02/05 13:01] Snowdrop Short smiles
[2009/02/05 13:01] Adelle Fitzgerald: it helped a lot
[2009/02/05 13:01] Snowdrop Short: good

[2009/02/05 13:02] Snowdrop Short smiles
[2009/02/05 13:02] Adelle Fitzgerald: then ckrinke threw the LSL bit
of opensim at me, so I looked at that...
[2009/02/05 13:02] eaglefx Binder: i tried to open up all the
OpenSIm, but PHEEEEEEEEEEEEEW what a whole lot of stuff ... i hurried

[2009/02/05 13:03] Snowdrop Short smiles
[2009/02/05 13:03] Jeff 1564: the docs still loading for ever
[2009/02/05 13:03] Snowdrop Short: it is big
[2009/02/05 13:03] eaglefx Binder: i think i will never find anything
in the right pane
[2009/02/05 13:03] Snowdrop Short: one of the tricks of programming
is focussing on only a few things
[2009/02/05 13:03] Snowdrop Short: so don't let the size ooverwhelm
you
[2009/02/05 13:04] Adelle Fitzgerald nods
[2009/02/05 13:04] eaglefx Binder: ok i have some LDAP stuff that i
wanna focus on, i found some good examples
[2009/02/05 13:04] eaglefx Binder: ;)
[2009/02/05 13:04] Adelle Fitzgerald: i can see how C# is broken down
into little bits, much like lsl, the syntax is similar too
[2009/02/05 13:05] Starky Rubble: C# seems a lot lot my old MS Access
stuff - even to the forms
[2009/02/05 13:05] Starky Rubble: is it just VBA reimagined?
[2009/02/05 13:05] Snowdrop Short: actually c# is very much inspired
by Java
[2009/02/05 13:06] Snowdrop Short: and inspired by Java
[2009/02/05 13:06] Snowdrop Short: java on the otherhand has much
inspiration from c++
[2009/02/05 13:06] Snowdrop Short: which is an extension to c
[2009/02/05 13:07] Starky Rubble: K&R
[2009/02/05 13:07] Snowdrop Short: which was an extension to A
[2009/02/05 13:07] Snowdrop Short: which was created by some people
who hated Fortran and Cobol
[2009/02/05 13:07] Starky Rubble: right
[2009/02/05 13:07] paulie Flomar: there was no B?
[2009/02/05 13:07] Snowdrop Short: Cobol was made in disgust of
Fortrans as welll
[2009/02/05 13:07] Snowdrop Short: yes
[2009/02/05 13:08] Snowdrop Short: which grew into Beta
[2009/02/05 13:08] Snowdrop Short: :-)
[2009/02/05 13:08] Starky Rubble: Yep
[2009/02/05 13:08] paulie Flomar: fascinating :)
[2009/02/05 13:08] Starky Rubble: history
[2009/02/05 13:08] eaglefx Binder: http://www.novell.com/coolsolutions/feature/11204.html,
i'm gonna have a look into this one here and see if that can be used
for any.
[2009/02/05 13:08] Snowdrop Short: and Fortran was the first
programming language ever made
[2009/02/05 13:09] Snowdrop Short: lets try this one
[2009/02/05 13:09] Starky Rubble: And Cobol the first by a woman
wasn't it?
[2009/02/05 13:09] Snowdrop Short: more luck?

[2009/02/05 13:15] Snowdrop Short: let's forget about that for now
[2009/02/05 13:15] Snowdrop Short: I will hand them out when we need
them
[2009/02/05 13:15] Starky Rubble: buying isnt working
[2009/02/05 13:15] Starky Rubble: good
[2009/02/05 13:15] paulie Flomar: heh
[2009/02/05 13:15] Adelle Fitzgerald: could you pasetbin it for us,
program by program? if the notes dont load?
[2009/02/05 13:16] Snowdrop Short: good suggestion
[2009/02/05 13:16] paulie Flomar: yeah
[2009/02/05 13:16] Jeff 1564: good one adlelle
[2009/02/05 13:16] Snowdrop Short: does everybody know what that
means
[2009/02/05 13:16] paulie Flomar: yep
[2009/02/05 13:16] eaglefx Binder: yep
[2009/02/05 13:16] Starky Rubble: nope
[2009/02/05 13:16] Snowdrop Short: ok
[2009/02/05 13:16] M1sha Dallin: nope
[2009/02/05 13:16] BlueWall Slade: the perms are still no copy, no
mod, no transfer
[2009/02/05 13:16] Snowdrop Short: a pastebin, is a place on the
internet
[2009/02/05 13:16] Snowdrop Short: where you can upload some text
[2009/02/05 13:16] Snowdrop Short: and it will be stored there,
temporarily
[2009/02/05 13:16] Snowdrop Short: you are given an URL
[2009/02/05 13:17] Snowdrop Short: and you can give that URL to
others
[2009/02/05 13:17] Snowdrop Short: and then they can see the text you
uploaded
[2009/02/05 13:17] Starky Rubble: hmmph
[2009/02/05 13:17] Adelle Fitzgerald: people use it on IRC a lot for
sharing things like opensim.ini and long error messages
[2009/02/05 13:17] Snowdrop Short: I would have preferred to use
OpenSim Technology
[2009/02/05 13:17] Starky Rubble: yes
[2009/02/05 13:18] eaglefx Binder: whats with these notes here, why
do they not load? server issues?
[2009/02/05 13:18] Snowdrop Short: I don't know
[2009/02/05 13:18] Snowdrop Short: we'll try to figure out later :-)
[2009/02/05 13:18] Starky Rubble: ok
[2009/02/05 13:18] Snowdrop Short: so has everybody got their IDE
started?
[2009/02/05 13:19] Jeff 1564: yea
[2009/02/05 13:19] Adelle Fitzgerald: yep
[2009/02/05 13:19] Snowdrop Short: ok
[2009/02/05 13:19] Snowdrop Short: the way I plan for this to happen
is
[2009/02/05 13:19] Snowdrop Short: that I'll show you a program
[2009/02/05 13:19] Snowdrop Short: and then you and the person next
to you will dicuss it in IM
[2009/02/05 13:20] Snowdrop Short: and figure out what it does,
[2009/02/05 13:20] Snowdrop Short: maybe run it
[2009/02/05 13:20] Snowdrop Short: and then we'll talk about it
[2009/02/05 13:20] Snowdrop Short: in here
[2009/02/05 13:20] Snowdrop Short: we'll start with something very
simple
[2009/02/05 13:20] Snowdrop Short: (I didn't know where to start
really)
[2009/02/05 13:20] Jeff 1564: hello C# :)
[2009/02/05 13:21] Snowdrop Short: and then progress from there to
something a little more comples
[2009/02/05 13:21] Snowdrop Short: complex, even
[2009/02/05 13:21] Snowdrop Short: the first one is a classic, with
just a very minor twist
[2009/02/05 13:21] Snowdrop Short: so start up, and create a new c#
console project
[2009/02/05 13:22] eaglefx Binder: empty one?
[2009/02/05 13:22] Jeff 1564: ready

[2009/02/05 13:23] Snowdrop Short: blank/empty will not work
[2009/02/05 13:23] Jeff 1564: new project
[2009/02/05 13:24] Jeff 1564: console application
[2009/02/05 13:24] Snowdrop Short: in your IDE you should see some
files
[2009/02/05 13:24] eaglefx Binder: yes thats what i too
[2009/02/05 13:24] eaglefx Binder: k
[2009/02/05 13:24] Snowdrop Short: yes, console application
[2009/02/05 13:24] eaglefx Binder: allrighty
[2009/02/05 13:24] Snowdrop Short: forget about all of them, except
the Main.cs
[2009/02/05 13:24] Snowdrop Short: that's the interesting one
[2009/02/05 13:25] M1sha Dallin: program.cs?

[2009/02/05 13:48] Snowdrop Short: okay
[2009/02/05 13:48] eaglefx Binder: cant the lagmeter tell?

[2009/02/05 13:49] M1sha Dallin: opening the notecard
[2009/02/05 13:49] Adelle Fitzgerald: we just created a new project
[2009/02/05 13:49] eaglefx Binder: yeps
[2009/02/05 13:49] robert omegamu: unable to open program one lol
[2009/02/05 13:49] eaglefx Binder: post it on the wiki
[2009/02/05 13:49] eaglefx Binder: i have a wiki too
[2009/02/05 13:50] robert omegamu: ..
[2009/02/05 13:50] Starky Rubble: hee first it was the "how to say a
time" hurdle
[2009/02/05 13:51] Snowdrop Short: ok
[2009/02/05 13:51] Starky Rubble: now "passing out class notes"
[2009/02/05 13:51] Snowdrop Short: I think I'm back now
[2009/02/05 13:51] Snowdrop Short: Jeff will pass out a pastebin URL
[2009/02/05 13:51] Snowdrop Short: delete all the text in Program.cs
or Main.cs depending on you ide
[2009/02/05 13:52] Snowdrop Short: and insert the text from the
pastebin
[2009/02/05 13:52] Adelle Fitzgerald nods
[2009/02/05 13:52] robert omegamu: ok
[2009/02/05 13:52] Starky Rubble: k
[2009/02/05 13:53] Snowdrop Short: http://www.pastebin.ca/1328383
[2009/02/05 13:53] Snowdrop Short: here it is
[2009/02/05 13:53] Snowdrop Short: I know this program is very simple
[2009/02/05 13:53] Snowdrop Short: but we have to start somewhere
[2009/02/05 13:53] Snowdrop Short: M1sha and Starky
[2009/02/05 13:54] Snowdrop Short: I suggest you IM together
[2009/02/05 13:54] Snowdrop Short: eaglefx and jeff you are a team
[2009/02/05 13:54] Starky Rubble: yep
[2009/02/05 13:54] Snowdrop Short: and Adelle and robert are a team
[2009/02/05 13:54] eaglefx Binder: ok
[2009/02/05 13:54] Jeff 1564: ready here
[2009/02/05 13:54] Snowdrop Short: IM together, and discuss it
between you
[2009/02/05 13:54] Adelle Fitzgerald: if you get trouble with
pastebin putting the line numbers in, there is a 'raw' button at top
rist of web page, click that then copy/paste
[2009/02/05 13:54] Snowdrop Short: and then yell out when you are
ready for a discussion in open forum
[2009/02/05 13:55] Snowdrop Short: let me know if you have any
problems
[2009/02/05 13:56] Jeff 1564: we have a namespace Lesson1
[2009/02/05 13:56] Starky Rubble: Should we run it?
[2009/02/05 13:56] Jeff 1564: ops..
[2009/02/05 13:56] Snowdrop Short: if you want to
[2009/02/05 13:56] Snowdrop Short: maybe that can help you understand
it better
[2009/02/05 13:57] Starky Rubble: I love hello World but i don't see
how to run it it MS 2008
[2009/02/05 13:57] Snowdrop Short: what goes wrong?
[2009/02/05 13:57] eaglefx Binder: i just pasted it over all of the
new project page was that tryue?
[2009/02/05 13:58] Adelle Fitzgerald: Starky, top menu: debug -->
start without debugging
[2009/02/05 13:58] Adelle Fitzgerald: or hit F5
[2009/02/05 13:58] Snowdrop Short smiles
[2009/02/05 13:58] Adelle Fitzgerald: i mean ctrl + F5
[2009/02/05 13:58] Starky Rubble: heh
[2009/02/05 13:58] Snowdrop Short: that is part of the excercise
[2009/02/05 13:58] Snowdrop Short: learning to use the IDE
[2009/02/05 13:59] Snowdrop Short: it is quite an excercise, just
like learning a word processor or drawing program
[2009/02/05 13:59] Snowdrop Short: ctrl-f5 on MS
[2009/02/05 14:00] Jeff 1564: Console.ReadKey();
[2009/02/05 14:00] eaglefx Binder: Dang man it works :P
[2009/02/05 14:00] eaglefx Binder: yuuhoo
[2009/02/05 14:00] Snowdrop Short: yes, what about it?
[2009/02/05 14:00] Snowdrop Short: the Console.ReadKey();
[2009/02/05 14:00] eaglefx Binder: well i didnt know how it would,
but i see thats pretty cool
[2009/02/05 14:01] Snowdrop Short: what happens when you run it is
that it is converted into machine language
[2009/02/05 14:01] Snowdrop Short: and executed by the cpu
[2009/02/05 14:02] M1sha Dallin: It runs fine- but syntax is not
clear compared with Ada or Ada95
[2009/02/05 14:02] Snowdrop Short: (I've skipped a few steps, but we
must crawl before we walk)
[2009/02/05 14:02] Snowdrop Short: has everybody gotten it to run?
[2009/02/05 14:02] robert omegamu: yes
[2009/02/05 14:02] Starky Rubble: we have
[2009/02/05 14:02] Snowdrop Short: on Mono-Develop
[2009/02/05 14:02] Jeff 1564: :)
[2009/02/05 14:02] Snowdrop Short: you have to run it from the
command line
[2009/02/05 14:03] Snowdrop Short: ok
[2009/02/05 14:03] Snowdrop Short: are we ready to debate the
program?
[2009/02/05 14:03] eaglefx Binder: sure
[2009/02/05 14:03] Starky Rubble: Sure
[2009/02/05 14:03] Jeff 1564: i do
[2009/02/05 14:03] M1sha Dallin: yep
[2009/02/05 14:03] Adelle Fitzgerald: yeppers
[2009/02/05 14:04] Snowdrop Short: Ok .. we'll start from the inside
and work our way out
[2009/02/05 14:04] Snowdrop Short: what does:
"Console.WriteLine....." do?
[2009/02/05 14:04] Jeff 1564: hello world in your console
[2009/02/05 14:04] robert omegamu: it writes hello world
[2009/02/05 14:04] Starky Rubble: wriets a line to the console
[2009/02/05 14:04] M1sha Dallin: write the string parameter
[2009/02/05 14:05] Snowdrop Short: yes
[2009/02/05 14:05] Adelle Fitzgerald: it writes the message string
between the quotes tot eh console
[2009/02/05 14:05] Jeff 1564: M1sha PRO :)
[2009/02/05 14:05] Snowdrop Short: the string, the text in the
quotes, is written to the console
[2009/02/05 14:05] eaglefx Binder: ir read the key typed
[2009/02/05 14:05] Starky Rubble: and a linefeed
[2009/02/05 14:05] Snowdrop Short: we are using a simple constant
string
[2009/02/05 14:06] eaglefx Binder: it should print type your input ;)
[2009/02/05 14:06] Snowdrop Short: do you have a "Console.ReadLine
();" as well?
[2009/02/05 14:06] Adelle Fitzgerald: no
[2009/02/05 14:07] eaglefx Binder: no
[2009/02/05 14:07] Snowdrop Short: ok
[2009/02/05 14:07] robert omegamu: no
[2009/02/05 14:07] Snowdrop Short: let's forget about that one
[2009/02/05 14:07] eaglefx Binder: it was a suggestion
[2009/02/05 14:07] Snowdrop Short: what does the semicolon do?
[2009/02/05 14:07] robert omegamu: tells it to move to the next line
[2009/02/05 14:07] eaglefx Binder: end of line ?
[2009/02/05 14:07] Starky Rubble: ends the line of code
[2009/02/05 14:07] Adelle Fitzgerald: it denotes the end of that
current command
[2009/02/05 14:07] Jeff 1564: is better if your not in runnign from
the console
[2009/02/05 14:07] eaglefx Binder: using system; whats that?
[2009/02/05 14:08] Snowdrop Short: yes, it marks the end of the
"statement"
[2009/02/05 14:08] Snowdrop Short: actually it's not the line
[2009/02/05 14:08] Snowdrop Short: you can have several statements on
a line
[2009/02/05 14:08] Snowdrop Short: although that isn't common
[2009/02/05 14:08] Snowdrop Short: and sometimes frowned upon by the
pro's
[2009/02/05 14:09] eaglefx Binder: what are the first 3 lines? doing?
[2009/02/05 14:09] eaglefx Binder: 4 maybe
[2009/02/05 14:09] Snowdrop Short: lets work our way out
[2009/02/05 14:09] eaglefx Binder: ok
[2009/02/05 14:09] Snowdrop Short: what does the { and } mean?
[2009/02/05 14:09] Starky Rubble: code block wrappers
[2009/02/05 14:10] Jeff 1564: open and close a function etc...
[2009/02/05 14:10] eaglefx Binder: tuborg klammer ,) hehe
[2009/02/05 14:10] Snowdrop Short: in danish, yes
[2009/02/05 14:10] M1sha Dallin: delimit a block?
[2009/02/05 14:10] Starky Rubble: What I used to call a procedure or
a function
[2009/02/05 14:10] Snowdrop Short: curly braces in english
[2009/02/05 14:10] robert omegamu: begin and end of statment
[2009/02/05 14:10] Snowdrop Short: yes, they delimit a block of
statments
[2009/02/05 14:10] Adelle Fitzgerald: curly braces that show the
start and end of that particular statement
[2009/02/05 14:10] eaglefx Binder: allrighty
[2009/02/05 14:10] Adelle Fitzgerald: ahh statements
[2009/02/05 14:10] Adelle Fitzgerald: :)
[2009/02/05 14:11] Snowdrop Short: { tells the compiler that now it
will encounter a list of statements
[2009/02/05 14:11] Snowdrop Short: and the } indicates, an end to the
list
[2009/02/05 14:11] Snowdrop Short: so a block { } can have multiple
statements, each of them separated by semicolons
[2009/02/05 14:11] Starky Rubble: sets the scope of the block?
[2009/02/05 14:12] Snowdrop Short: that too, although we'll hold off
on scope for a few days
[2009/02/05 14:12] eaglefx Binder: so why aint there any above the
namespace then?
[2009/02/05 14:12] Snowdrop Short: because that is the outer block
[2009/02/05 14:12] Snowdrop Short: the outer MOST block, even
[2009/02/05 14:12] eaglefx Binder: ok, well
[2009/02/05 14:13] Hello Metaverse!
[2009/02/05 14:13] Snowdrop Short: a lot of the things we write in
the code, is there to make life easier for the compiler
[2009/02/05 14:13] eaglefx Binder: and those are blue for some
reason?
[2009/02/05 14:13] Snowdrop Short: the program which tranlates from
c# into machine code
[2009/02/05 14:13] eaglefx Binder: ah i know machine code ;)
[2009/02/05 14:13] Jeff 1564: public static void Main(string[] args)
inisde class MainClass inside namespace Lesson01
[2009/02/05 14:13] Snowdrop Short: the colors are there to help you
see what is where
[2009/02/05 14:13] eaglefx Binder: ok
[2009/02/05 14:14] eaglefx Binder: sorry if i'm too newbie, but how
else to learn ;)
[2009/02/05 14:14] Snowdrop Short: when you get a little more used to
the IDE, the colors helps guide your eyes
[2009/02/05 14:14] Snowdrop Short: the only dumb question, it the
question not asked
[2009/02/05 14:14] eaglefx Binder: okay np
[2009/02/05 14:14] Snowdrop Short: that's why we are here, to have
our questions answered
[2009/02/05 14:15] eaglefx Binder: but looks like i can use this for
something
[2009/02/05 14:15] Snowdrop Short: so what is the "public static void
Main(string[] arg]) all about?
[2009/02/05 14:15] eaglefx Binder: i didnt know you could make a
console application this easy
[2009/02/05 14:16] eaglefx Binder: some microsoft thing?
[2009/02/05 14:16] Snowdrop Short: Mono has it too
[2009/02/05 14:16] Snowdrop Short: and it is an absolute must
[2009/02/05 14:16] Adelle Fitzgerald: the public static thingy if
'that' block of statements..
[2009/02/05 14:16] Snowdrop Short: any program must have one and only
one of those
[2009/02/05 14:16] Adelle Fitzgerald: oh
[2009/02/05 14:17] Snowdrop Short: any guesses?
[2009/02/05 14:17] M1sha Dallin: defines the function 'main'
[2009/02/05 14:17] eaglefx Binder: in human language what would it
translatye to?
[2009/02/05 14:17] Starky Rubble: main
[2009/02/05 14:17] Jeff 1564: is your main function... something to
do.....
[2009/02/05 14:17] Snowdrop Short smiles
[2009/02/05 14:18] eaglefx Binder: oki
[2009/02/05 14:18] Snowdrop Short: yes, it is true, but the word Main
has a special significance
[2009/02/05 14:18] Adelle Fitzgerald: oh! a bit like the 'default'
state in lsl?
[2009/02/05 14:18] Snowdrop Short: if you think about it
[2009/02/05 14:18] eaglefx Binder: so it would always be like Main?
[2009/02/05 14:18] Snowdrop Short: when the operating system loads
your program
[2009/02/05 14:18] M1sha Dallin: the main program?
[2009/02/05 14:18] Jeff 1564: adelle kind of
[2009/02/05 14:18] Snowdrop Short: it sees only a stream of
instructions
[2009/02/05 14:18] Snowdrop Short: but where in the stream should it
start to execute from
[2009/02/05 14:19] Snowdrop Short: in this case it is pretty simply,
there is only one place
[2009/02/05 14:19] Snowdrop Short: but in a large program?
[2009/02/05 14:19] M1sha Dallin: always entry point for function
main?
[2009/02/05 14:19] Snowdrop Short: so by convention, it has been
decided that the operating system should start executing the block of
code in the FUNCTION main
[2009/02/05 14:20] Snowdrop Short: and end the program, when it has
executed all the statements in the block
[2009/02/05 14:20] Snowdrop Short: so we have a function called Main
(yes there is a difference between main and Main)
[2009/02/05 14:20] eaglefx Binder: will all programs start like that?
[2009/02/05 14:20] Snowdrop Short: (capitals matter)
[2009/02/05 14:20] Snowdrop Short: yes, all c# programs start like
that
[2009/02/05 14:21] Snowdrop Short: Main is always where the program
starts
[2009/02/05 14:21] Jeff 1564: yes when you learn talk your learn
probably or mom heheh
[2009/02/05 14:21] Jeff 1564: :)
[2009/02/05 14:21] eaglefx Binder: so like OpenSim there is alot of
Mains or only one?
[2009/02/05 14:21] Snowdrop Short: one per server
[2009/02/05 14:22] Snowdrop Short: so the sim has one
[2009/02/05 14:22] Snowdrop Short: the U-ser server has one
[2009/02/05 14:22] eaglefx Binder: ah ok
[2009/02/05 14:22] Snowdrop Short: and so on for each of the UGAIM
[2009/02/05 14:22] eaglefx Binder: good to know
[2009/02/05 14:22] eaglefx Binder: what about modules then
[2009/02/05 14:22] eaglefx Binder: also a main each
[2009/02/05 14:22] Snowdrop Short: reading a program is like
unwinding a bundle of yarn
[2009/02/05 14:22] Snowdrop Short: but you always know where to start
[2009/02/05 14:22] Snowdrop Short: "Main"
[2009/02/05 14:22] M1sha Dallin: is that a main or Main for modules?
[2009/02/05 14:23] Jeff 1564: M
[2009/02/05 14:23] Snowdrop Short: modules are a bit different,
because they are extensions
[2009/02/05 14:23] M1sha Dallin: ok
[2009/02/05 14:23] Snowdrop Short: not real programs
[2009/02/05 14:23] Snowdrop Short: but the extensions are loaded by
real programs
[2009/02/05 14:24] eaglefx Binder: i have been wondering if i wanted
to write a module for opensim, and it has a place in the OpenSim.ini
will then that be a Main of its Own? kinda like the IRC Module?
[2009/02/05 14:24] Adelle Fitzgerald: so, the only Main exists in the
actual executable application, at machine level?
[2009/02/05 14:24] Snowdrop Short: yes
[2009/02/05 14:24] Snowdrop Short: it is always there, in any
executable
[2009/02/05 14:24] Snowdrop Short: and by convetion, it is called
Main in c#
[2009/02/05 14:25] Starky Rubble: Im lost by the Module references
[2009/02/05 14:25] Snowdrop Short: that's ok, it is not an easy thing
[2009/02/05 14:25] Starky Rubble: ok
[2009/02/05 14:25] Snowdrop Short: quite complex, but I hope well get
to it
[2009/02/05 14:25] Starky Rubble: ok back to Masin then
[2009/02/05 14:25] eaglefx Binder: okay, in a few years ;)
[2009/02/05 14:25] Snowdrop Short: essentially a sim server is "just"
program
[2009/02/05 14:26] Snowdrop Short: and has a Main
[2009/02/05 14:26] Starky Rubble: right
[2009/02/05 14:26] Snowdrop Short: but it is a quite complex program,
and can extend itself
[2009/02/05 14:26] Snowdrop Short: while it is running
[2009/02/05 14:26] Starky Rubble: right
[2009/02/05 14:26] Snowdrop Short: those extensions are called
modules
[2009/02/05 14:26] Starky Rubble: ah
[2009/02/05 14:27] eaglefx Binder: are this C# only to make .exe's or
can it be compiled to run native on Linux too?
[2009/02/05 14:27] Snowdrop Short: they are not real programs, just
chunks of code, which the Main program knows how to use
[2009/02/05 14:27] Jeff 1564: mono
[2009/02/05 14:27] Starky Rubble: got it
[2009/02/05 14:27] Snowdrop Short: you can copy a .net exe from MS to
LINUX and it will generally run
[2009/02/05 14:27] Snowdrop Short: and vice versa
[2009/02/05 14:27] eaglefx Binder: ok
[2009/02/05 14:27] Snowdrop Short: it is very portable, just like
java
[2009/02/05 14:28] Snowdrop Short: that is one of the reasons for
using c# for opensim
[2009/02/05 14:28] eaglefx Binder: C# = C++ and so on? same look and
feel is that right?
[2009/02/05 14:28] Jeff 1564: .net id kinf of java virtual machine
[2009/02/05 14:28] Snowdrop Short: no, c++ isn't c#
[2009/02/05 14:28] eaglefx Binder: ok
[2009/02/05 14:28] Starky Rubble: no Glbal Vars for instance
[2009/02/05 14:29] Snowdrop Short: no global variables
[2009/02/05 14:29] eaglefx Binder: C# is a Microsoft invention?
[2009/02/05 14:29] Snowdrop Short: I'm actually very fond of c#, I
think it is a great language
[2009/02/05 14:29] Snowdrop Short: yes, invented my microsoft, and
then made a standard language
[2009/02/05 14:30] M1sha Dallin: So everything must be in a class
with accessor functions?
[2009/02/05 14:30] eaglefx Binder: ok
[2009/02/05 14:30] Snowdrop Short: so anybody can use the language
[2009/02/05 14:30] Snowdrop Short: we are getting ahead of ourselves,
but yes M1sha
[2009/02/05 14:30] Snowdrop Short: ok, I have one more for you
[2009/02/05 14:30] M1sha Dallin: ok ty - and sorry
[2009/02/05 14:30] Snowdrop Short: np, we can talk about it after
class if you'd like

[2009/02/05 14:31] Snowdrop Short: I have a new one for you
[2009/02/05 14:32] eaglefx Binder: you should have a desk and a board
up there to paste up the lines as we do too ;)
[2009/02/05 14:32] Snowdrop Short: you can either just replace the
text
[2009/02/05 14:32] Snowdrop Short: or create a new project
[2009/02/05 14:33] Snowdrop Short: let me know when you are ready
[2009/02/05 14:33] robert omegamu: ok
[2009/02/05 14:33] M1sha Dallin: Gives the wrong answer
[2009/02/05 14:33] Adelle Fitzgerald: got it
[2009/02/05 14:33] Snowdrop Short: M1sha?
[2009/02/05 14:33] Jeff 1564: ready
[2009/02/05 14:34] eaglefx Binder: ready
[2009/02/05 14:34] Jeff 1564: compiled
[2009/02/05 14:34] Jeff 1564: and working
[2009/02/05 14:34] Jeff 1564: :)
[2009/02/05 14:34] eaglefx Binder: build succeded :P
[2009/02/05 14:34] Snowdrop Short: M1sha+Delvina+eaglefx .. should
form a team
[2009/02/05 14:34] Snowdrop Short: Starky+Adelle
[2009/02/05 14:34] Starky Rubble: Ok we got it
[2009/02/05 14:35] Snowdrop Short: Jeff+robert
[2009/02/05 14:35] eaglefx Binder: Ok
[2009/02/05 14:35] Starky Rubble: ok
[2009/02/05 14:35] Jeff 1564: ok
[2009/02/05 14:35] Snowdrop Short: talk it over internally
[2009/02/05 14:35] Snowdrop Short: and let me know when you are ready
to discuss
[2009/02/05 14:35] eaglefx Binder: but we cant be 3 in a IM can we?
[2009/02/05 14:35] Snowdrop Short: no, so you should use open chat,
or IRC,
[2009/02/05 14:36] eaglefx Binder: ok
[2009/02/05 14:36] Snowdrop Short: #osgrid-college on freenode, could
be a choice
[2009/02/05 14:36] eaglefx Binder: Okay yes maybe better
[2009/02/05 14:37] Starky Rubble: OK we tthink there is an error
[2009/02/05 14:38] Adelle Fitzgerald: it works for me
[2009/02/05 14:38] Snowdrop Short: M1sha+Delvina+eaglefx should go to
IRC or talk in open chat
[2009/02/05 14:38] Snowdrop Short: what is the problem Starky
[2009/02/05 14:38] Snowdrop Short: there is a bug in the application,
but it should still run
[2009/02/05 14:38] Jeff 1564: run ok here
[2009/02/05 14:38] Snowdrop Short: I'm hoping you'll find my mistake
[2009/02/05 14:39] M1sha Dallin: you write that you are calculating
3! but pass teh parameter 5
[2009/02/05 14:39] Snowdrop Short smiles and nods
[2009/02/05 14:39] Snowdrop Short: true
[2009/02/05 14:39] Snowdrop Short: it is acutally a piece of bad
design on my part
[2009/02/05 14:40] robert omegamu: ok just gunna say whooosh ?????
that went so over the top of the old head lol
[2009/02/05 14:40] Snowdrop Short smiles, well talk it over, in
public
[2009/02/05 14:40] Jeff 1564: :)
[2009/02/05 14:41] Jeff 1564: i know you did that just to see if we
will find out
[2009/02/05 14:41] M1sha Dallin: It's al lin the Console.WriteLine
("The factorial of {0}={1}", 3, Factorial(5));
[2009/02/05 14:41] Snowdrop Short: later on I'll show an improved
version
[2009/02/05 14:41] M1sha Dallin: It's writing a line of text
containing to numeric parameters
[2009/02/05 14:41] Snowdrop Short: let me know when you are ready to
discuss in public
[2009/02/05 14:42] M1sha Dallin: denoted by {0} and {1} in the string
part
[2009/02/05 14:42] Starky Rubble: Yes we think the text 3 dhould be a
5
[2009/02/05 14:42] M1sha Dallin: or the factorial (5) should be
factorial(3)
[2009/02/05 14:43] Adelle Fitzgerald: i dont understand 'factorial'
[2009/02/05 14:43] Starky Rubble: and the (0)=(1) is stinky
[2009/02/05 14:43] robert omegamu: whats factorial
[2009/02/05 14:43] Snowdrop Short: what is wrong with the {0} and {1}
[2009/02/05 14:44] Snowdrop Short: factorial is a mathematical
function
[2009/02/05 14:44] Snowdrop Short: calculating 1*2*3* ... *n
[2009/02/05 14:44] Adelle Fitzgerald: ahhhh
[2009/02/05 14:44] Snowdrop Short: uptill the number needed
[2009/02/05 14:44] Snowdrop Short: so factorial(5) is: 1*2*3*4*5
[2009/02/05 14:44] Starky Rubble: specifed in the parens
[2009/02/05 14:44] Snowdrop Short: and factorial 3 is 1*2*3
[2009/02/05 14:45] Adelle Fitzgerald: gotcha :)
[2009/02/05 14:45] Starky Rubble: what is the {0}={1} for?
[2009/02/05 14:45] Adelle Fitzgerald: the {0} & {1} are in curly
braces so dont actually do anything, right?
[2009/02/05 14:46] Snowdrop Short: it is use by the .net run time
[2009/02/05 14:46] Adelle Fitzgerald: oh...they must though
[2009/02/05 14:46] M1sha Dallin: I believe they identify which of the
following parameters are substituted
[2009/02/05 14:46] Starky Rubble: isn't it an assignment?
[2009/02/05 14:46] Snowdrop Short: when Console.WriteLine prints out
the line
[2009/02/05 14:46] Snowdrop Short: it looks at the text it is
printing
[2009/02/05 14:47] Snowdrop Short: and tries to find any numbers in
braces
[2009/02/05 14:47] Starky Rubble: ohh args
[2009/02/05 14:47] M1sha Dallin: so the string value of the numeric 3
is placed where {0} is in the string
[2009/02/05 14:47] Snowdrop Short: like {0}, {1}, {3} and so on
[2009/02/05 14:47] Snowdrop Short: it will replace that with the
value after the text
[2009/02/05 14:47] Snowdrop Short: each value is separted by comma's
[2009/02/05 14:48] Snowdrop Short: so it replaces {0} with 3
[2009/02/05 14:48] Snowdrop Short: and it replaces {1} with what?
[2009/02/05 14:48] Adelle Fitzgerald: ahh, i get it :D
[2009/02/05 14:48] Starky Rubble: I get it - the 3 and the Factotial
() are arguments 0 and 1 respectivelly for the Console.Write
[2009/02/05 14:48] Adelle Fitzgerald: Factorial(3)
[2009/02/05 14:49] Snowdrop Short: that's the question, what happens
with {1}?
[2009/02/05 14:49] Starky Rubble: its evaluated
[2009/02/05 14:49] Adelle Fitzgerald: it runs the 'static int' loop 3
times
[2009/02/05 14:50] Adelle Fitzgerald: called upon by the reference
'Factorial'?
[2009/02/05 14:50] Snowdrop Short: remember that I called Main a
function?
[2009/02/05 14:50] Snowdrop Short: Factorial is a funtion
[2009/02/05 14:50] Snowdrop Short: only I decided on the name
"Factorial"
[2009/02/05 14:51] Snowdrop Short: it could have had any name
[2009/02/05 14:51] eaglefx Binder: ah ok
[2009/02/05 14:51] Adelle Fitzgerald: so a function is something that
happens outside of Main?
[2009/02/05 14:51] Snowdrop Short: like Banana or Jonesey
[2009/02/05 14:51] Snowdrop Short: yes, other wise Main would grow
very very long
[2009/02/05 14:52] Snowdrop Short: if everything was inside main
[2009/02/05 14:52] eaglefx Binder: is there a function in this one? i
see sort of a counter
[2009/02/05 14:52] Snowdrop Short: so we can define new functions,
and write statements inside their codeblocks
[2009/02/05 14:52] Snowdrop Short: remember the { ... } talk
[2009/02/05 14:52] Snowdrop Short: and the list of statements
[2009/02/05 14:52] Adelle Fitzgerald: and you can call upon the same
function time and tme again passing it different variables each time
to cut down on the length of code, and more importantly the memory
used by the app
[2009/02/05 14:52] Snowdrop Short: true
[2009/02/05 14:53] Snowdrop Short: you can reuse the function, again
and again
[2009/02/05 14:53] Snowdrop Short: that's a skill in it's own right
[2009/02/05 14:53] Snowdrop Short: figuring out what functions to
make
[2009/02/05 14:54] Snowdrop Short: it is part of what is called
"design"
[2009/02/05 14:54] Starky Rubble: ok but the {0}={1} part
[2009/02/05 14:55] eaglefx Binder: it would be great with comments
inside those lessons! to maybe understand those better. for
starters ;)
[2009/02/05 14:55] Snowdrop Short: so the compiler knows it needs to
execute a function called "Factorial", and goes out looking for where
that function is defined
[2009/02/05 14:55] Snowdrop Short smiles
[2009/02/05 14:55] Snowdrop Short: there is purpose behind the
madness
[2009/02/05 14:55] Snowdrop Short: you see, I wan't you to read the
code, not the comments
[2009/02/05 14:55] eaglefx Binder: hehe i figured ;)
[2009/02/05 14:55] Snowdrop Short: sometimes the comments are wrong
[2009/02/05 14:56] eaglefx Binder: okay np
[2009/02/05 14:56] Snowdrop Short: so it replaces {0} and {1} with
the actual values
[2009/02/05 14:56] Snowdrop Short: and eventually prints out
[2009/02/05 14:57] Snowdrop Short: "The factorial of 3=120"
[2009/02/05 14:57] Snowdrop Short: which is where the program error
is
[2009/02/05 14:57] Snowdrop Short: because 1*2*3 is acutally 6
[2009/02/05 14:57] Snowdrop Short: so if I hadn't made a mistake, I
would have said
[2009/02/05 14:57] Snowdrop Short: "The factorial of 3=6"
[2009/02/05 14:58] Adelle Fitzgerald: what would factorial actually
be used for?
[2009/02/05 14:58] Snowdrop Short: it is used in probaility theory
[2009/02/05 14:58] M1sha Dallin: How many ways can you arrange 3
items on a desk?
[2009/02/05 14:58] Snowdrop Short: for counting ways in which you can
combine things
[2009/02/05 14:58] Adelle Fitzgerald: gotcha
[2009/02/05 14:59] Snowdrop Short: if you have a blue, red and green
ball
[2009/02/05 14:59] Snowdrop Short: you can arrange them in factorial
(3) different ways
[2009/02/05 14:59] Primitive: Script running
[2009/02/05 14:59] Snowdrop Short: (Discovered by a french monk in
15hundred and something called Blaise Pascal"
[2009/02/05 14:59] eaglefx Binder: ahhh Pascal :P
[2009/02/05 14:59] Primitive: Script running
[2009/02/05 15:00] Primitive: Script running
[2009/02/05 15:00] Snowdrop Short: any questions so far?
[2009/02/05 15:00] M1sha Dallin: nope
[2009/02/05 15:00] Adelle Fitzgerald: im good :)
[2009/02/05 15:00] Jeff 1564: i m fine
[2009/02/05 15:00] eaglefx Binder: i think i have a few hundred but i
better just read a little on this ;)
[2009/02/05 15:00] Starky Rubble: Ok, what if you wanted to say "The
factorial of 3=6 and the factorial of 5=120" - would there be a {3}=
{4}?
[2009/02/05 15:00] Snowdrop Short: try changing it so it calculates
factorial 12
[2009/02/05 15:00] Snowdrop Short: no
[2009/02/05 15:01] Adelle Fitzgerald: I'm taking down the chat log,
I'll find some way of distributing it afterwards to those that want
it :)
[2009/02/05 15:01] Snowdrop Short: you have to numbers after the
string, separted by comma
[2009/02/05 15:01] Snowdrop Short: so it will crash at runtime,
looking for the 3rd and 4th values after the message
[2009/02/05 15:01] M1sha Dallin: The factorial of 12=479001600
[2009/02/05 15:02] Snowdrop Short: but if you write:
[2009/02/05 15:02] Snowdrop Short: Console.WriteLine("The factorial
of {0}={1}and the factorial of {2} = {3}", 3, Factorial(3),5, Factorial
(5));
[2009/02/05 15:03] Snowdrop Short: it would work and print
[2009/02/05 15:03] Starky Rubble: Oh... zero counting bit me
again!!!!
[2009/02/05 15:03] M1sha Dallin: :-)
[2009/02/05 15:03] Starky Rubble: Arrggh
[2009/02/05 15:03] Snowdrop Short: "The factorial of 3=6and the
factorial of 5 = 120"
[2009/02/05 15:03] Snowdrop Short: all programmers start from 0
[2009/02/05 15:03] Snowdrop Short: you should start doing that
[2009/02/05 15:04] Snowdrop Short: always count from 0, never 1
[2009/02/05 15:04] Starky Rubble: Doh!
[2009/02/05 15:04] eaglefx Binder: hehe
[2009/02/05 15:04] Snowdrop Short: 0 is probably the biggest
invention made
[2009/02/05 15:04] eaglefx Binder: after the wheel
[2009/02/05 15:05] Snowdrop Short: nobody know when the wheel was
invented
[2009/02/05 15:05] eaglefx Binder: lol
[2009/02/05 15:05] Starky Rubble: (verging on philosophy lol)
[2009/02/05 15:05] Snowdrop Short: but zero was - it is believed -
invented by the arabs in about 965
[2009/02/05 15:05] Starky Rubble: Babalonians
[2009/02/05 15:05] Snowdrop Short: ad
[2009/02/05 15:05] eaglefx Binder: well anyways u sure got me
confuswed now, i think i will sleep better now .. hehe
[2009/02/05 15:06] Starky Rubble: ylonians lol
[2009/02/05 15:06] Snowdrop Short: yes, it is getting late
[2009/02/05 15:06] Snowdrop Short: do you want to break and continue
next
[2009/02/05 15:06] Adelle Fitzgerald: any integer always starts at 0,
always..
[2009/02/05 15:06] Snowdrop Short: or should we continue
[2009/02/05 15:06] eaglefx Binder: it is allright with me i stay up
until 02:00 anyways
[2009/02/05 15:06] Adelle Fitzgerald: im good to continue
[2009/02/05 15:06] Starky Rubble: yes and Case always matters and
never forget the ";"
[2009/02/05 15:07] Snowdrop Short smiles and nod to Starky .. true
[2009/02/05 15:07] Adelle Fitzgerald: most errors when writing when
tired are syntax, always syntax... when tired ;)
[2009/02/05 15:07] Snowdrop Short: true
[2009/02/05 15:07] Starky Rubble: and the == /= = part
[2009/02/05 15:07] Snowdrop Short: never write programs when you are
tired
[2009/02/05 15:08] Snowdrop Short: and do not code under the
influence
[2009/02/05 15:08] Starky Rubble: and thats 90% of my problrms in the
old days
[2009/02/05 15:08] Adelle Fitzgerald chuckles
[2009/02/05 15:08] Snowdrop Short: inside the messge?
[2009/02/05 15:08] Adelle Fitzgerald: most of my lsl was done tired
and sometimes under the influence, that tought me to check syntax
again and again ;)
[2009/02/05 15:08] Snowdrop Short: somethins are best, when you are
sober ::P
[2009/02/05 15:08] Starky Rubble: no the assignment vs equals in
general
[2009/02/05 15:09] M1sha Dallin: I need to go - many thanks Snowdrop
[2009/02/05 15:09] Snowdrop Short: ok
[2009/02/05 15:09] Snowdrop Short: You are welcome M1sha
[2009/02/05 15:09] Starky Rubble: Yeah I should run too
[2009/02/05 15:09] Snowdrop Short: it is my pleasure to try to give
something back
[2009/02/05 15:09] Adelle Fitzgerald: bye M1sha :)
[2009/02/05 15:09] Starky Rubble: Thanks Snowdrop
[2009/02/05 15:09] M1sha Dallin: bye all
[2009/02/05 15:09] Jeff 1564: bye
[2009/02/05 15:09] Adelle Fitzgerald: bye Starky
[2009/02/05 15:09] Starky Rubble: with all the problems it worked out
well
[2009/02/05 15:10] Snowdrop Short: ok, I think we should round it up
[2009/02/05 15:10] Adelle Fitzgerald nods
[2009/02/05 15:10] Snowdrop Short: but before we split
[2009/02/05 15:10] eaglefx Binder: good starters, here, but you need
a teacher board ;)
[2009/02/05 15:10] Snowdrop Short: I would like to hear from you
[2009/02/05 15:10] Snowdrop Short: how to make it better
[2009/02/05 15:10] Starky Rubble: beyon the nuts and bolts part lol
[2009/02/05 15:10] robert omegamu: use pastebin for sure lol for now
anyway lol
[2009/02/05 15:11] Starky Rubble: yes
[2009/02/05 15:11] Adelle Fitzgerald: just need to get notecards
working here
[2009/02/05 15:11] Snowdrop Short nods
[2009/02/05 15:11] Starky Rubble: mine is still loading lol
[2009/02/05 15:11] Snowdrop Short: this is very much an experiment
[2009/02/05 15:11] Adelle Fitzgerald: or better still, copyable text
from a prim and VNC on a prim too! ;)
[2009/02/05 15:11] eaglefx Binder: it would be great if the text came
up here on a board as well, i imagine
[2009/02/05 15:12] robert omegamu: it may be an idea to place them in
the sim some time before class give people a chance to get them before
the sim fills up
[2009/02/05 15:12] Snowdrop Short: I doubt there has been any
attempts in teaching c# inside a metaverse before
[2009/02/05 15:12] Starky Rubble: nebs got a board that will show the
pastebin
[2009/02/05 15:12] eaglefx Binder: hehe
[2009/02/05 15:12] Snowdrop Short: so I'm just as much a newbie as
you guys
[2009/02/05 15:12] eaglefx Binder: Oh cool yes
