I've been using Serendipity for a couple of years and really love it now. But sometimes I wish it could be faster. Different servers tell a difference, but an average generation time for example for one category listing with 15 entries takes about 5 seconds or more. So I couldn't wait any longer, since I've learned Varnish Cache, to toggle it between Serendipity and the end user. Of course, Varnish would limit some blogging features, but the benefits will be worth of that. Sounds interesting? So this article is for you.

A couple of years ago I've shared my expierience about how to setup virtual mail hosting with Postfix and Dovecot. Some time ago I needed to make that accessible via Web. So, a webmail.
After trying a couple of engines I've decided in favour of SquirrelMail. This worked like a charm with SSL, etc. so the full mailing functionality was available just out of the box. The one thing I was still missing was a possibility to change password. There are already several plugins to achieve the goal, for instance when logging in over LDAP, but nothing could really fit for me. That's because the maildir setup I'm using is non standard. Luckily, the SquirrelMail API is simple and just well documented, so I was able to write a custom change password plugin very fast.

There is a new PHP extension I've written to work with Varnish. The extension allows interaction from within a PHP script with a running Varnish instance. For now there is a basic useful functionality such as ban URLs or set/get Varnish configuration. There will be more with the time. For now I would give a couple of examples for the extension usage, as there is not really any docs for the extension here.

This time I needed some geographical data evaluation for one of my current projects. The data used to be opensource and as possible qualitative and complete. After spending some time in front of the famous search engine window there was a solution:
http://www.geonames.org/
That's the first sentence from the site:
The GeoNames geographical database covers all countries and contains over eight million placenames that are available for download free of charge.
Geonames is used by number of sites. Besides data it has also web services and code libraries in many programming languages to access them.

Hi again,
whole last week I was mad about hearing music. I've heared tons of mp3's and radio stations over the internet. After a couple of days hearing music at work and at home I was really bored with creating and syncronizing playlists/files. Based on this, I came to the idea to make an online playlist which I would must update only one time and in one place and it would be accessible from anywhere. The idea was easy brougth out with PHP. So just a light reading for you:

Hey you all (and me too) web developers. The huge important news today is - now we can send IMs from a script running within a web server - isn't it cool? Only one restriction conditioned by libpurple itself is there - use is definitely safe within CGI environment only. The second important news, as you see from the title - the project was renamed to Phurple. Furthermore there are a couple essential changes I was made as refactoring of the code was written so far.
Became interested? Lets look onto most important points in the changelog:

So, new PHPurple version was issued yesterday and is downloadable from sf.net. What's inside:
* PurpleAccount::isConnecting() added
* PurpleAccount::getUserName() added
* PurpleAccount::getPassword() added
* PurpleClient::deleteAccount() added
* PurpleClient::findAccount() added
* PurpleClient::addAccount returns now a PurpleAccount instance (but was null)
* PurpleClient::authorizeRequest() added
The most interesting thing there is of course the remote client authorization.

Today I've maked the second PHPurple release and changed it's status to alpha. The changes, came into it, are:
* fixed zts compatibility
* implemented the loopHeartBeat method
* the runLoop method was changed to set the heartbeat interval
* fixed memory leak on empty alias
* purple.debug_enabled is now boolean
The most interesting on this release is the PurpleClient::loopHeartBeat() story, which is of course implemented with g_timeout_add. Take a look at the new example script to see how it works.

Referencing my previous article about the mali server configuration, I'm continuing with spam and antivirus scanners setup. On my Debian box i'm installing the following:
BASH: user@host~$ apt-get install spamassassin
With this groups spamd and clamav are automatically created. Before you start, keep in mind - if something goes wrong, allways check the /var/log/mail.* files.

About a month ago I've written a simple domain checker, which is using whois.net to get the domains availiable. The main goal was to find free 3-symbols domains.
BASH: #!/bin/sh
if [ $# -lt 1 ]
then
echo "usage: `basename $0` extension
Check domains avaliability
examples:
`basename $0` com
";
exit 2;
fi
EXT=$1;
LAST_FILENAME=/tmp/dc_$USER$EXT.last
if [ -f "$LAST_FILENAME" ]; then LAST_DOMAIN=`cat $LAST_FILENAME`; fi
for DOMAIN in {{0..9},{a..z},-}{{0..9},{a..z},-}{{0..9},{a..z},-}
do
if [ "$DOMAIN" \< "$LAST_DOMAIN" ]; then continue; fi
trap "echo $DOMAIN > $LAST_FILENAME;exit;" SIGHUP SIGINT SIGTERM
STATUS_STRING=`wget -qO - http://www.whois.net/whois_new.cgi\?d\=$DOMAIN\&tld\=$EXT | grep 'Status'`
echo "$STATUS_STRING" | grep 'free' &&
echo "$DOMAIN.$EXT" >> ~/domains_found_$EXT.txt &&
echo "the domain is free: $DOMAIN.$EXT" | mail -c my@mail.com -s "free domain" other@mail.com
sleep 7
done
The thing is very simple and the results can be kept on. Additionally it sends mail messages about each found domain. Lets see, what it brought for the .de domains ( about 9000 free domains was found  )

The first pre-alpha is released and can be downloaded at http://sourceforge.net/projects/phpurple/. The common documentation I've started to make was placed to http://phpurple.rubay.de/.
The main features implemented are:
- send and recieve IMs
- fully implemented account dsn like string
- ability to make account specific settings
- basic work with buddy, buddy group and buddy list
The license was changed to the BSD like proprietary license.

An interesting question I had to answer a couple months ago was - how could I compile an executable statically, so then it works on various linux distributions without the need to install some additional libs. Of course, such the executables are bigger as that, which was compiled in order to use the dynamic libs. But if one wanna to have an independent production executable, this is what one could need.
So, I will explain the thing with the help of an example program, which uses ncurses. First I'm creating the project dir, for example:
BASH: user@host~$ mkdir ~/programming/static_test
user@host~$ cd ~/programming/static_test

Yesterday I was configuring the mail server on my hosting. Because I'm mostly doing programming, not administration, I'm writing this notes which are serving as a simple how to, if I must do it once more in a couple of years.
In spite of the fact I've done all on Debian, all the described things schould work on some other Linux distribution as well. First install Postfix and Dovecot
The configuration will fulfill the following points:
- IMAP over SSL
- SMTP over SSL (Postfix using Dovecot SASL)
- Multiple domains with virtual users
- Mailing possibility for the local users
- Mailboxes in the Maildir format

and so it will be in the future ...
Namely, i had the excellent oo design suggestion from the Alexey on the pecl mailing list (and it is better, than I could invent), and it works fully for php 5.3 and unfortunately partly for php 5.2. So lets take a look on it ... just get the latest version ...
CODE: user@host~# svn co https://phpurple.svn.sourceforge.net/svnroot/phpurple/trunk phpurple

Some time ago i've started to write the binding for the libpurple, the im lib. About 3-4 weeks ago i had a simple functional implementation, which i've presented on php pecl and libpurple mailing lists. Subsequently i've completely revised the whole thing to be OO and would present it again. There is the same minimal functionality implemented, but all is OO. So, lets begin. First install the php development package and get the code:
CODE: user@host~# svn co https://phpurple.svn.sourceforge.net/svnroot/phpurple/trunk phpurple
