Candy Shop from the album "Candy Shop - Single" by 50 Cent

Go here and get libidn. This is needed by jabberd and OS X doesn't ship with it.

./configure
make
sudo make install

Step 2. - Get mysql

Go here and get and install the Standard mysql. This is also needed by a default jabber server - which is what we want.

This comes as a dmg so install it and the start-up script for mysql. Also the default installation is /usr/local/mysql - This is important because we need to know where the libraries are. To find this out:

cd <mysql install dir>/bin
mysql_config --libs

Remember this line as it defines where we need to look for libraries.. I got this from the docs..

Step 3. - Get jabberd

Go here and get the jabberd-2.0s6. Note the standard link on jabberd.org does work..

Now we want to compile mysql into this and let me say what a PITA!!! However, after debugging it I thing the right thing to do is two things. YMMV of course.

I edited the configure file on line 20269 from
for incpath in /usr/include/mysql /usr/local/include/mysql; do
to
for incpath in /usr/include/mysql /usr/local/mysql/include /usr/local/include/mysql; do

then I did ..

export LDFLAGS="-L/usr/local/mysql/lib/mysql -lmysqlclient -lz -lm $LDFLAGS"; ./configure --enable-debug --sysconfdir=/etc/ --enable-mysql --with-extra-include-path=/usr/local/mysql/include --with-extra-library-path=/usr/local/mysql/lib

make

It should end with this - which is OK.

ld: warning empty table of contents: ../subst/.libs/libsubst.a (can't load from it)

sudo make install

From there it was a simple. I followed the instructions and added a few of my own..
Change the pid,db,and log file locations

In this piece I will detail how to get perforce and XCode to play nicely.

Ok I figured out how to get perforce to work on my linux box. And now I have a place to play. How do I want the directory structure to fit is a common question. So let me outline how I think I want my development environment setup. I've bee a long time hacker, and this is the first time I want to enable perforce SCM for all of my development (perhaps others) activities. So how do I want this setup? When I am finished I want a directory structure that looks like this:
<some base directory>

scripts

perl
python
.
.

projects

proj1 (Some XCode or other project)
proj2
.
.
projN

So this seems simple enough - and it is. After a bit of trial and error playing with P4CLIENTS I have this setup. So let's assume you have a server (called server).

Ensure you have an empty base directory. For this example I created a directory on my client ( mkdir ~/depot ). Next create a client workspace. I used p4v to do this and simply did the following:

• Open Connection (File->Open Connection)

• Connect To: < your server and port >
• Connect As: < your username > ( if this is the first time you must select New.. )
• Client Workspace:

• I named one steven and selected New..
• Under the name I called it steven

• Owner: Steven
• Host: <default>
• Description: Steven depot
• Root: <base directory>

Now you should have a empty directory tree. Let's add our appropriate directories.

mkdir ~/depot/scripts/python
mkdir ~/depot/projects

Ok now let's put a file in the python directory and use p4v to check the thing in.

cp <my python script> ~/depot/scripts/python

Ok switch over to the p4v and refresh the Client Workspace. Seeing your new file right click and "open for add", then right click "submit"

Cool it should work. Now let's get xcode to play nicely..

Step 2 - Create a XCode project for python

This is very basic - fire up XCode ( get it from here ) and create a new empty project.

• The type is an Empty Project
• Give is a <project name>
• The directory needs to be <base directory>/projects/<project name> ( ~/depot/projects/PythonTest1 )

And that's it. Now let's add SCM - version control..

Step 3 - Getting Perforce to play nicely.

One of the things I despise is when documentation points you to a particular place and no amount of searching seems to dig up the answer. So you dig and dig and finally piece together the appropriate answer. Such is the documentation for getting XCode to play with Perforce. Assuming you're an XCode junkie the docs are straightforward enough. For this part time player - I was unnerved by the following statement that was stated in the docs under the section of Perforce.

"Open the project in Xcode and set the SCM system to Perforce. See Xcode Help for details."

So what the hell does this mean? Perhaps preferences? No. Perhaps it's per project - don't know. Time for google (like life in general) - After a big of digging I find out. I need to see an inspector.. This can be found by either right clicking under the top most group and saying get info or under File->Show Inspector.

Once this is up all you need to do is under the General Tab at the bottom enable SCM. and edit the appropriate options.

• perforce tool path (/usr/local/bin/p4)
• P4PORT ( hostname:port )
• P4CLIENT ( from above - I called my steven )
• Username and Password ( from above )

At this point you should have a perforce enabled environment.

"CVS was designed by hamsters on crystal meth."

Well if your a sole hacker and want something to use personally that's FREE - use perforce it'll save you time and energy. And you won't have UGLY CVS files all over the place - Yuck.

I will install this the sysadmin way - and allow ssh tunneling to occur so I can limit who has access to my repository

1.) You develop something that you would like to have version control over. That something is represented by 1's and 0's and can be seen on a computer screen.
2.) You have access to a Linux Machine. (Not necessary but for this install yes it is - and NO I won't help you on your windows box )
3.) You have a connection to the internet.
4.) You have some brains - they help :)

Ok, that's outa the way. Check out the following links.

• Perforce Quick Start for New Users
• Perforce User's Guide

So go get perforce. Pull p4 p4d (if you want p4v too)

Install it by doing the following:
# cp p4 /usr/local/bin/
# chmod 755 /usr/local/bin/p4
# cp p4d /usr/local/bin/

So that was easy - now let's get a perforce user and group defined..
# groupadd -g 500 perforce
# adduser -u 500 -g perforce -d /home/depot -s /bin/false perforce

Now let's put this in the local start up scripts as a daemon..

start-stop-daemon --start --quiet --chuid perforce:perforce \
--exec /usr/sbin/p4d \
-- -q -L /var/log/perforce \
-J /mnt/local/perforce/journal \
-p 1667 -d -r /home/depot

Ok then kick it over.. See her start up -- voila!

Now using p4v attempt to connect to localhost:1666 If you can your in business!!

Now let's get some authentication going.. First things first - p4 protect to set up basic protections

# p4 protect

Modify it so only user foo can write to my repository..

Protections:
write user foo * //...
super user root * //...

And save the file. This gives superuser access (root) and foo has (write) access. Now let's limit how we gain access from outside of our network..

Creating an ssh port forwarder.. On our client run the following:
ssh <linux-box> -L 1666:localhost:1667

This sets up a secure tunnel to the remote 1667 port using my local 1666 port. Way cool. Now I can connect to it anytime I want to from outside my network.

Now what makes it easier is to add the following to your ~/.ssh/config file

Host tunnel
User <user-name>
Hostname <linux-box>
LocalForward 1666 localhost:1667
GatewayPorts no

Now in the future all I have to do type ssh tunnel and the tunnel is created!! Once this is created now you simply connect to the localhost port 1666 and it magically and securely heads over to the the linux box! Way cool!

Or if you run a mac pull this cool little app!

OK enough for today.

wget http://www.pycs.net/bbum/2004/1/21/readline.so.gz
gunzip readline.so.gz
sudo mv readline.so /Library/Python/2.3

Get readline and install the .so into the python tree..

Time to Start from the album "The Complex" by Blue Man Group

Ok I have a slightly different DNS setup. I want to query a specific host for DNS resolution but do the "normal" thing for everything else. Additionally I want to be a local domain server for my home intranet. Oh and if that wasn't enough of a challenge, I want the intranet domain to be .local and I'm running macs. (If you don't know this, mac's don't like to resolve the .local domain it's local... ) Here is how you go about it

( I assume that you have already obtained djbdns and followed the instructions to get it installed )

Note: Keep in mind that if you want to run BOTH a cache and a DNS server you need two IP's.. Linux can easily do this with aliasing!

Part 1 - Setting up a simple DNS cache

This is the easy part and is well documented.. Follow these instructions

Don't forget when you get done - verify that resolv.conf points to the server and check it..

dnsip www.cnn.com

Part 2 - Get your company intranet domains to be resolved by the company's intranet DNS Server

I work for company foo and I happen to have a VPN connection to the site. But I can't resolve any of foo's internal addresses because they aren't public. So I want to defer my queries for foo.com to a different ( internal server )
This is also documented but in a not-so-easy place. You must know the internal DNS server(s) of the company foo. So using them..

cd /service/dnscache

echo <DNS SERVER> > root/servers/foo.com
echo <DNS SERVER2> >> root/servers/foo.com
chmod 644 root/servers/foo.com
svc -t .

Don't forget when you get done - verify we can get an IP for an internal name

dnsip hostname.foo.com

Part 3 - Getting .local to be resolved..

We have two problems to solve. First we want to build a local dns server to resolve the .local domain. This will allow you to type ping machine-name as opposed to ping ip-address. This is useful and handy. The second problem is that Mac OS doesn't like to have other machines answer to the .local domain. In their eyes that is a reserved name.. Kinda stupid but we'll fix that.

Get the tinydns server up and working. Follow the instructions here.. Use the instructions all the way until you've checked the addresses of your computers. Since we are only publishing internally, we don't care about the rest.. So we will follow the same instructions as above ..

cd /service/dnscache

echo <DNS SERVER> > root/servers/local
chmod 644 root/servers/foo.com
svc -t .

Don't forget when you get done - verify we can get an IP for an internal local name

dnsip <host>.local

Now we need to have the mac actually search .local for DNS queries.. Mac treats .local only as Rendezvous hosts. So no DNS queries ever happen with .local domains. This can be fixed by following the instructions here

Don't forget to test it on the mac!!

OK were done now..

function ssh_login () {
# This function will get a passwordless authentication session setup for you.
# It is a resuble function in that you can use it at the top of any script
# prior to any ssh'ing to ensure you can do it passwordless. The goal was to
# simply have the user enter his password once.
if [ ! $1 ] ; then
print "Dork, I need an destination argument"
return 255
else
if [ ! -e ~/.ssh/id_rsa -o ! -e ~/.ssh/id_rsa.pub ] ; then
print "Dork, You need to make your keys.."
print "ssh-keygen -t rsa -b 1024 -f ~/.ssh/id_rsa -C \"My comment\""
return 254
fi
# print "Running with comments"
ssh -o RSAAuthentication=yes -o PasswordAuthentication=no \
-o kbdinteractiveauthentication=no -o challengeresponseauthentication=no \
-o StrictHostKeyChecking=no -o CheckHostIP=no $1 date 2>&1 > /dev/null
if [ $? -ne 0 ] ; then
# So we can't get there - let's fix the problem..
# print "Unable to use pawwordless authentication - pushing key now"
cat ${HOME}/.ssh/id_rsa.pub | ssh $1 \
'if [ ! -d ~/.ssh ] ; then
mkdir ~/.ssh/
fi
chmod 700 ~/.ssh
touch ~/.ssh/authorized_keys
chmod 600 ~/.ssh/authorized_keys
cat >> ~/.ssh/authorized_keys'

if [ $? -ne 0 ] ; then
print "Fatal error - must do this manually.."
return 1
else
# print "Pushed key successfull - testing function"
$0 $1 $2
fi
else
# We are good to go..
# print "Success"
return 0
fi
fi
}

So now if I have another function or script that does something like..

function push_dotfiles(){
rsync -avz --recursive -e ssh ~/.profile $1:~/
rsync -avz --recursive -e ssh ~/.zshenv $1:~/
rsync -avz --recursive -e ssh ~/.zshrc $1:~/
.
.
.
rsync -avz --recursive -e ssh ~/.cds/ $1:~/.cds/
}

I would modify it so it does this first..

function push_dotfiles(){
ssh_login $1
rsync -avz --recursive -e ssh ~/.profile $1:~/
rsync -avz --recursive -e ssh ~/.zshenv $1:~/
rsync -avz --recursive -e ssh ~/.zshrc $1:~/
.
.
.
rsync -avz --recursive -e ssh ~/.cds/ $1:~/.cds/
}

Have fun!!

Clear all variables..
CleanSlate[]

Substitute

(x+y)(x-y)^2 /. {x->3, y->1-a}

Defining a functions..
f[x_]:x^2
f[2]

I really need a place to put these things..

Pretty simple but it took me 30 minutes to find this one..

Thanks to Jason Cowart for this one.

Mummers Dance from the album "The Book of Secrets" by Loreena McKennitt

It appears on the surface like a good idea, and sticking to techie stuff should remain pretty harmless. But now simply saying product xyz sucks ass won't fly either. Now I will be required to substantiate it a bit more. Ok fine, that will help me articulate my thoughts more clearly anyway.

So I'm in - I just hope the system they put in place gives me the freedom to modify and change it so works the way I want it to work.
