Hello world!

Dudes, Wordpress is pretty easy to install. Took me 4.35 minutes. My awesome host (Black Dog Hosting) hooked me up pretty quickly. He has PHP 4.4.4 and Mysql 5.0.32. I’m suprised he hasn’t upgraded to Php 5. When are we gonna see Php 6? I think that people will have the same reaction to Php 6 will probably be like Perl 6: Who cares, we’re all using Ruby and Python now ! Damn, I just burned my whole Php readership. This blog is off to a bad start.

Awesome incident of the month
By admin
I'm (finally) getting more structured and object-oriented with my JavaScript. My co-worker is a guru at this stuff.
I was working on an awesome class called FirstTree. It was super-object-oriented. I went to go use it in my code like this:
var myObject = FirstTree.new({config: configuration});
I pounded my head on this for like 20 minutes. Why was it giving some strange error?!?!? I thought JavaScript would let me be object-oriented!
So, I asked the guru to look at my code. And he pointed out, “Dumbass, you write that line of code like this”:
var myObject = new FirstTree({config: configuration});
Moral of the story: Stop thinking in Ruby!
Apache SSL with 2 IPs and 2 Certificates
By admin
Yesterday we had to set up Apache to host 2 SSL certificates for 2 different IPs. There’s all kind of crackheads on the internet who think you can install 2 SSL certificates for 1 IP but it simply can’t be done. So, here’s what I did:
There’s info on the Apache VirtaulHost Examples site. The best examples are “Mixed name-based and IP-based vhosts” and “Mixed port-based and ip-based virtual hosts.”
Let’s say we have 2 domains: mauka.com and makai.com.
We change our DNS so that the IP xx.xx.xx.1 points to mauka.com and xx.xx.xx.2 points to makai.com points to xx.xx.xx.2. This means the server has to be set up with 2 IPs.
Before we change anything in Apache, we need to generate 2 ssl certificates. We will make these wildcard certificates for the names *.mauka.com and *.makai.com. There’s plenty of information out there about how to generate the key, this site has some good stuff: http://www.madboa.com/geek/openssl/
So, we generate our keys and certs and place them in /etc/pki/tls/private/wildcard-makai.key, /etc/pki/tls/certs/wildcard-makai.crt, /etc/pki/tls/certs/wildcard-mauka.crt and /etc/pki/tls/private/wildcard-mauka.key.
Here’s what the set up will look like for our domain to configure the following urls. :
http://www.mauka.com
http://www2.mauka.com
https://www.mauka.com
https://www2.mauka.com
http://www.makai.com
http://www2.makai.com
https://www.makai.com
https://www2.makai.com
in the main http.conf
NameVirtualHost xx.xx.xx.1:80 NameVirtualHost xx.xx.xx.2:80
Add after our mod_ssl setup, for us it is a file ssl.conf
DocumentRoot /www/www.mauka.com ServerName www.mauka.com DocumentRoot /www/www2.mauka.com ServerName www2.mauka.com DocumentRoot /www/www.makai.com ServerName www.makai.com DocumentRoot /www/www2.makai.com ServerName www2.makai.com
SSL Configurations
Add after our mod_ssl setup, for us it is a file ssl.conf

Note: This is very general, there’s a lot of other options that are missing here. This is to give you an idea of what it looks like.

git: Get a single file from another repository
By admin
This is so easy it's almost stupid. Let's say want to copy a single file from b0 to another branch, b1, without doing a merge and all that crap. all you do is this:
# change to b1
get-checkout b1
# checkout the single file
git-checkout b0 path/to/file
Then you can do something like to see the differences:
git-diff HEAD path/to/file
and when you are done:
git-commit -m “Commit it, baby” path/to/file
“Commit it, baby” as a comment is mandatory.
Make irb remember your history with the irbrc
By admin
I always forget this one too. To make ruby's irb remember commands you entered in the last session(s), you need to add the following lines to /home/kenglish/.irbrc:
require 'irb/completion'
require 'irb/ext/save-history'
IRB.conf[:SAVE_HISTORY] = 100
IRB.conf[:HISTORY_FILE] = “#{ENV['HOME']}/.irb-save-history”
IRB.conf[:PROMPT_MODE] = :SIMPLE
Isn't IRB-RC an awesome name for a file?
isn't Camber First
git – adding e-mail alerts & hooks
By admin
Before you do anything, you may want to back up the file .git/hooks/post-receive in your project directory or at least view it to make sure that there's nothing in it.
Now, get a copy of the git source code:
git clone git://git.kernel.org/pub/scm/git/git.git
Overwrite the post-receive in your hook folder with the file git/contrib/hooks/post-receive-email :
cp git/contrib/hooks/post-receive-email /var/data/repos/myproject/.git/hooks/post-receive
Now, go to your project home and add the git-config variable:
cd /var/data/repos/myproject/
git-config hooks.mailinglist “kenglish@someweakdomain.org”
git-config hooks.mailinglist “[GIT-MYPROJECT] “
Now test it out, do a git-commit -a on your repository and push it to the master. Should send an e-mail about the checkin.
BONUS:
By default, the script will just e-mail you that files have checked in. If you want to Email the diffs of the files themselves, basically, copy the diff of from that guys post into your post-receive file. THen set hooks.emailprefix=1
with:
git-config hooks.emailprefix 1
Ignoring local changes
By admin
If You have something checked into the repository that you will change locally but never want to check back in, you can do this:
git update-index –assume-unchanged config/initializers/ruby_inline.rb
