The first try gave me this error:


? ~ rvm install 1.9.3-p125
Error running ' ./configure --prefix=/Users/antonio/.rvm/rubies/ruby-1.9.3-p125 --enable-shared --disable-install-doc --with-libyaml --with-opt-dir=/Users/antonio/.rvm/usr ', please read /Users/antonio/.rvm/log/ruby-1.9.3-p125/configure.log
There has been an error while running configure. Halting the installation.

Adding the compiler option “–with-gcc=clang” worked:


? ~ rvm install 1.9.3-p125 --with-gcc=clang
Install of ruby-1.9.3-p125 - #complete

enjoy Ruby :)

export BREW_HOME=/usr/local

brew install libxml2
brew link libxml2
brew install https://github.com/adamv/homebrew-alt/raw/master/duplicates/libxslt.rb
brew link libxslt
brew install libiconv
brew link libiconv
gem install nokogiri -- --with-xml2-dir=$BREW_HOME/Cellar/libxml2/2.7.8 --with-xslt-dir=$BREW_HOME/Cellar/libxslt/1.1.26 --with-iconv-dir=$BREW_HOME/Cellar/libiconv/1.13.1/
view raw gistfile1.bash This Gist brought to you by GitHub.

If you had MacPorts previously installed, it might still not work so
sudo mv /opt/local /opt/local_old
and try again.

Enjoy :)

Just reinstall the postgres gem and you are done…

map => array_map
grep => array_filter
Too lazy to give you examples .. I think you can work it out yourself.

Here it is:Brian’s php5-fpm : Brian Mercer

Happy 10.04! :)

You want to know why? The bugged Techie Guide!!!

On page 19, the script is completely wrong and drove me mad: variation-content should be variation_content and document.write(“</nosc” + “ript>”) should be document.write(“<nosc” + “ript>”);

So, here is he complete correct script:
<script>
var v = utmx(‘variation_content’, ‘Section1’);
if (v) {
document.write(
v.replace(“%%product_name%%”, “<? print $product_name ?>”).
replace(“%%product_price%%”, “<? print $product_price ?>”).
replace(“%%product_id%%”, “<? print $product_id ?>”));
document.write(“<nosc” + “ript>”);
}
</script>
<ul>
<li>Product name: <? print $product_name ?>
<li>Product price: <? print $product_price ?>
<li><a href=’buy.php?prod-id=<? print $product_id ?>’>
Buy Now</a>
</ul>
</noscript>

Adapt it to your code and be happy!

To do that, add the following function into the http section of your nginx configuration
map $scheme $fastcgi_https { ## Detect when HTTPS is used
default off;
https on;
}

and use the variable into your server section
fastcgi_param HTTPS $fastcgi_https;

Lazy explanation as usual :P

For some reasons the memory was not incremented as expected.
After googleing around for a solution I just had an intuition: could be suhosin? Indeed, the problem was in the suhosin module that is enable by default on Ubuntu: it does not allow to redefine the memory limit over the limit specified in the php.ini file.
To make ini_set work normally under Ubuntu, comment out the suhosin extension in /etc/php5/apachew/conf.d/suhosin.ini

;)

After having lost the best of my youth trying to fix this issue, I can’t remember exactly how I did it, but I came up with this idea of reinstalling ruby and… guess what? It did work!
So the lesson here is … whenever you upgrade to a major release of XCode, you have to reinstall all your macports. These commands can save your day or two:
$ sudo port selfupdate
$ sudo port sync
$ sudo port upgrade --force installed
