The good thing: You don’t need to use backports anymore – the sun-java6-bin/sun-java6-jre packages are available in the lenny non-free tree.

Therefore, the first thing to do is check your /etc/apt/sources.list if it checks for non-free packages (does not per default).

deb http://ftp.debian.org/debian/ lenny main non-free
deb-src http://ftp.debian.org/debian/ lenny main non-free

The rest stays mostly the same:

# update apt to include non-free packages
apt-get update

# install packets (java and subversion)
apt-get install sun-java6-bin sun-java6-jre
apt-get install subversion

# add symlink from /usr/bin/java to /bin/java for the cruisecontrol start script
ln -s /usr/bin/java /bin/java

# install apache (mainly for phpmyadmin) and php5 + cli
apt-get install apache2-mpm-prefork
apt-get install php5 php5-cli php5-dev
apt-get install php-pear make

# install xdebug (needed for phpunit)
pecl install xdebug
echo "zend_extension=/usr/lib/php5/20060613+lfs/xdebug.so" >> /etc/php5/cli/php.ini

# install phpunit and phpundercontrol via pear
pear upgrade --force pear
pear channel-discover pear.phpunit.de
pear channel-discover components.ez.no
pear install phpunit/phpunit
pear install --alldeps channel://components.ez.no/Graph
pear install --alldeps channel://pear.phpunit.de/phpundercontrol-0.5.0

# get and extract cruisecontrol
apt-get install unzip wget
cd ~
wget http://freefr.dl.sourceforge.net/sourceforge/cruisecontrol/cruisecontrol-bin-2.8.3.zip
unzip cruisecontrol-bin-2.8.3.zip -d /opt
cd /opt
ln -s cruisecontrol-bin-2.8.3 cruisecontrol

# run phpundercontrol modifications against cruisecontrol
phpuc install /opt/cruisecontrol

# first testrun
cd /opt/cruisecontrol
./cruisecontrol.sh

Running the command as root worked fine but, running as user “nagios” just gave no output – which translated to the error message “NRPE: Unable to read output error” on the Nagios NRPE Client.

After checking file permissions, any debug modes and logs i found… i finally got to /tmp and there was it: “127.0.0.1……”, a temporary file created by that particular check plugin. Since i tested the plugin first as root, the file had root-only permissions, and the plugin executed as nagios just stopped somewhere while not being able to use/overwrite that file.

I deleted that particular file, and everything works fine now…

Author description:

Complex Liquid Admin template that contains a login page as well as a modular content page that includes all the elements you could possibly need in your admin. From these elements you should be able to generate any required page.

Please open the preview to check out all the elements.

Liquid as oposed to a fixed size means all the screen real-estate is used in the most efficient manner possible and also eliminates compatibility issues with non-standard, very low or very high screen resolutions.

Tableless CSS coding, cross-browser compatible and very stylish. Impress your customers today !

The template includes all page .psd files as well as slices and should be Easy to customise with medium knowledge of Photoshop and CSS .

Later edit : This template also contains rectangular notification boxes (ex. positive, negative, site message etc.) like our FlexiAdmin, however the shots don’t show this. So if you need these no worries, you will find them in the download package.

I’m impressed with the details and “amount of work” you get for that small price. I’m definitely going to use this in some projects – at least in my own

After my six hour hassle of (trying to…) moving the boot partition from my old harddrive to the new one (see the full report/steps below), I was curious about the first performance test, which I used HD Tune for.

This is the result for my old harddrive, a Samsung HD642JJ:

Raw data:

HD Tune: SAMSUNG HD642JJ Benchmark

Transfer Rate Minimum : 55.0 MB/sec
Transfer Rate Maximum : 102.8 MB/sec
Transfer Rate Average : 83.0 MB/sec
Access Time : 13.2 ms
Burst Rate : 135.3 MB/sec
CPU Usage : 4.5%
Temperature : 25°C

And this is the result for my new SSD (OZC Apex SSD 120GB):

Raw data:

HD Tune: OCZ APEX_SSD Benchmark

Transfer Rate Minimum : 1.4 MB/sec
Transfer Rate Maximum : 172.7 MB/sec
Transfer Rate Average : 138.1 MB/sec
Access Time : 0.2 ms
Burst Rate : 129.5 MB/sec
CPU Usage : 5.5%
Temperature : 44°C

As I said before, I moved my bootpartition to the new drive. These are my subjective feelings about the new system:

• The Windows bootup isn’t that much faster, but I didn’t measure the startup time of the old harddrive. (Still too long…)
• Applications start much faster now. I think this really is the point where the ridiculous low access time of the SSD kicks in. Zend Studio i.e. is down from ~30 secs to 12. (And I haven’t switched the projects/workspace to a new SSD partition yet!)

The application startup speed, and working with big filecount-intensive projects were the main reasons for me to try out a SSD. So far (this still is my impression after only 2-3 hours of usage) I am very satisfied with the results.

The temperature of the SSD is ~20° warmer, but I think even 44°C is not high enough to care about.

In about one month I will provide you with even more subjective feedback

The steps for the Vista bootpartition-move, using Acronis True Image, should be these:

1. Boot from the Acronis True Image CD
2. Backup your boot partition from the old drive
3. Restore the backup to the new drive, mark the new partition active (Cloning didn’t work, because the SSD is much smaller, and the UI doesn’t let me clone just one partition)
4. Reboot from your Vista Installation disc
5. Repair the installation on your new drive (the log should show something about “missing bootmanager – fixed”)
6. Boot from your new SSD
7. If your bootpartition is not C, fix it this way: How to restore the system/boot drive letter in Windows
8. Done. Finished. Hopefully.. (At least, you should have 2 layers of backups to restart if something screws up…)

Just two small things OCZ could improve:

• Inform me as a customer, that there is no SATA cable in the retail box. Every other retail (SATA) harddrive I bought up to this day had at least one packed.
• As most of the customers will be “switchers” imho, ship something to help with the partition migration process. I will happily pay some more bucks, if it just works.

The application could not be installed. Try installing it again. If the problem persists, contact the application author. Error #0

The first step debugging this was to find out where the AIR application installer logs errors – which by default he does not. To activate installer logging, you have to put two files in your home directory (C:\Users\youraccountname\ on Vista or C:\Documents and Settings\youraccoutname\ on XP) called .airappinstall.log and .airinstall.log.

If those two files are present, the logging writes to them automagically.

The error I found there looked like this:

Installing C:\Dokumente und Einstellungen\***\Lokale Einstellungen\Temp\fla12.tmp\setup.msi
Error occurred; beginning rollback: [ErrorEvent type="error" bubbles=false cancelable=false eventPhase=2 text="1603" errorID=0]

From here on I was very sure that it has to do with privileges… (No, there is no context menu entry on AIR packages to “install as Administrator” or “run as”…)

Finally, I checked the windows event log, and found this:

Product: *** -- Error 1925. You do not have sufficient privileges to complete this installation for all users of the machine.  Log on as administrator and then retry this installation.

Why can’t they show this error at the installer instead of error #0?…

Yes, installing as Administrator solved the problem!

I will show you two very simple examples with all three methods – see for yourself why one should use DOMDocument

Sample 1:

<!DOCTYPE html
     PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
     "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="de" lang="de">
    <head>
        <title>example</title>
    </head>
    <body>
        <div id="fetchme">
            foobar
        </div>
    </body>
</html>

Scraping:

// explode
$dataFirst = explode('<div id="fetchme">', $sample);
$dataSecond = explode('</div>', $dataFirst[1]);
$result = trim($dataSecond[0]);
echo $result;

// regex
preg_match('#<div id="fetchme">(.*)</div>#is', $sample, $matches);
$result = trim($matches[1]);
echo $result;

// domdocument
$doc = new DOMDocument();
$doc->loadHTML($sample);
$element = $doc->getElementById('fetchme');
$result = trim($element->nodeValue);
echo $result;

All three methods get this very simple example right ($result will be ‘foobar’).

Adding complexity, two of them fail badly, because they do not know which closing tag belongs to which opening tag.

Sample 2:

<!DOCTYPE html
     PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
     "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="de" lang="de">
    <head>
        <title>example</title>
    </head>
    <body>
        <div>
            <div id="fetchme">
                foo
                <div>
                    bar
                </div>
            </div>
        </div>
    </body>
</html>

Scraping:

The scraping methods are the same as for the first example, but with different output:
The explode method returns: ‘foo <div> bar’
The regex method returns: ‘foo <div> bar </div> </div>’ (the non-greedy regex would return the same as the explode version).
The DOMDocument method returns ‘foo bar’, because nodeValue strips htmltags. But the DOMElement $element holds just the content of the div #fetchme as we wanted it. It gets it right again.

Sidenotes:

You should know, some sites do not follow the (x)html standards correctly and therefore DOMDocument can fail. It also likes to throw exceptions then, but besides complaining you can still use > 90% of the document. If you want to disable the exceptions, you could either do it with @$doc->loadHTML() or $doc->strictErrorChecking = false.

Conclusion:

Besides DOMDocument solving the tag-matching issues, it also provides a much cleaner way to do HTML scraping jobs imho. It also is a lot more fault tolerant, one could use xpath-queries against the document, etc.
