Fighting Spam on your blog

Having a successful blog has a disadvantage as well. Spambots love you. Well I don’t love spambots and because I was receiving lots of spam messages on my blog I decided to try a few anti-spam engines for WordPress and I like the one from El Rincón de Boriel best.

I think you have to tweak it a little bit to your liking (I couldn’t read the verification text at default level and I think I am human) but after that it’s quite okay. So what does it actually do? If you now enter a comment you have to repeat the text that is in a somewhat distorted image. If you are successful you are considered human 🙂

Revoltec LightWriter Fan

Recently I bought a cool fan, the Revoltec LightWriter. I have a server machine and the frontside of case is open, directly behind that space you can see all the harddrives. To keep the harddrives cool I first had a high end Papst fan running. At one of the local computershops, iComputers, I saw this really great Revoltec LightWriter.

It has LEDs on the blades of the fan and by spinning them around quickly it writes texts in the air, like “Reboot Your Mind”. The nicest thing is that it also writes the incoming air temperature.

LDAP Server

OpenLDAPFirst you start with a mailserver, then you decide you need your own webserver. But what to do with a webserver if you have no FTP server? Things evolve…and then suddenly you discover that something like an addressbook server exists! You need that for your mailserver! Okay, LDAP is not only to be used as an addressbook server, but just like the rest you have to start somewhere.

Ofcourse I choose an open source LDAP server, OpenLDAP. Installation was pretty easy and straight forward, but configuring LDAP seems to be not something that you do in a few minutes. I currently have a pilot running, testing to see if everything works fine.

I have tested a lot of schema’s as I wanted OpenLDAP to be compatible with Outlook. I have forgotten about that idea…to hard! But I really don’t understand why there is no proper schema that makes OpenLDAP fully Outlook compatible? Many people use Outlook, more than X500’s, etc… Perhaps, I am doing something wrong, please let me know!

Apache DSFor administrating I am using Apache DS. Nice tool! I am still thinking of installing a webadministration tool, but first I want to make sure my LDAP survives the pilot phase. Currenly it’s running on my Outlook clients internally and my webmail client. It all works fine this far!

Who stumbled upon my Nabaztag?

Internet is such a nice medium, got an email from the Nabaztag Blog, asking me if linking is a good idea. Sure! Best idea there is, linking is cool, linking is the internet 🙂 Some time ago I built an Nabaztag-Ear-Mover. A simple PHP-script that allows you to move the ears of any Nabaztag in the world. At the Nabaztag Blog you can read much more about the cool features and possibilities of Nabazag!

Webserver efficiency improved

It’s always a matter of balancing if you use old equipment to run your server, but thanks to the Apaches, PHPs and MySQLs of this world it can be done. It took me a while to find out where the biggest inefficiencies were on the server. The help of Apache Server monitor was very usefull here. One of the things that improved efficiency was telling Googlebot what to index and what not to index. Fortunatly Googlebot (the spideringtool of Google) visits me up to 100 times a day so it’s important to tell Google what to know. I use robots.txt files to let Google know what is to be done at a certain site.

Advanced User Statistics

My job is marketing professional for Netherlands largest software developer, Exact Software. That’s why I probably like visitor statistics and other data gathering tools so much. This blogs seems to be a great way to test these things. I love new technologies.

This blog is now running the following tools
UserOnline, see who is currently online
GeoTrack, see in detail the location of visitors
PHPMyVisits, advanced statistics for bigger sites
Webalizer, a standard statistics tool

Further more I have extended the number of websites and blogs this blog automatically notifies whenever I make an entry in the blog. Currently the total is 32 other sites and blogs. It’s just a number, the strength is in the possibility. Perhaps in my next blog I will tell you a little bit more about the marketing data gathering tools 😉


My newest addition to my weblog is to show which users are currently on my site. I love dynamic content and to see what is actually happening to my blog. A live example of the current visitor, yes you!, is below here. Also a links, top left, is displaying how many users are currently online, and you can browse it yourself by clicking the link in the Page section. In a later stage I will also integrate this tool with my website Thanks go out to Lester Chan who developed this nice gadget.
