I found a couple of pretty interesting videos on Youtube showing how people are succeptible to subliminal messages. I’m not sure about the authenticity of what’s demonstrated in the videos but it certainly is an intriguing possibility.

I added to the Downloads section a small Silverlight application I wrote for an Algorithms course I’m taking. It’s basically a visual demonstration of the Delaunay triangulation. My implementation of the algorithm is based on Paul Bourke’s “Efficient Triangulation Algorithm Suitable for Terrain Modelling” and I want to express my gratitude for his great job. You can check out the app at the Downloads section.

This Wednesday I successfully presented the first part of my Senior Project at AUBG - the Web Metrics Monitor (WMM) project. The purpose of the project is to provide a robust, user-friendly and accessible web analytics tool. So far I’ve implemented the basic functionality and user interface. The back-end is implemented in PHP and includes a data retrieval module collecting the data, “engine” that is doing the processing of the raw data, and a data transfer module that is responsible for sending the summarized data to the UI. The data transfer module is making use of AMFPHP to send the data to the FLEX UI. As for the UI - it is available both as a Web app and as a desktop app via AIR. Here is a list of the metrics that are collected so far: Read more

I needed to use a DateTimeAxis for my senior project, but encountered a strange problem - data points were displayed with varying offset relative to the corresponding ticks on the x-axis. I couldn’t find anything explaining why this might be happening in the Flex documentation. Luckily, I found a very simple solution/explanation of the problem here. [Actually the displayLocalTime=”true” solution from the comments is even simpler and worked for me]

After experiencing some problems caused by my hosting providers switching to PHP5, I finally upgraded to 2.5.1. However, the del.icio.us and BadBehavior plugins are not functioning entirely correctly. I had to edit the del.icio.us plugin not to display the “added xx ago” string because it was giving an error from the date() function. The problem with the BadBehavior plugin was that it wasn’t displaying correctly the stats at the page footer - resolved by simply unchecking the corresponding box in the settings.

I recently watched a video on YouTube about the privacy issues with Facebook. It shows a bunch of interesting facts about the Terms of Service and funding sources of Facebook that certainly caught my attention and made me think if I want to keep on posting real info about myself on such Social Networks. The video is worth watching:

I was adding automated mailing lists to the admin panel of Radio AURA’s website when I noticed that the university firewall was blocking email from the server for some reason when I was using PHP’s mail(). Then I decided to use PHPMailer and send the e-mails through Gmail’s SMTP servers but PHPMailer was returning an error. After switching the debug option on, I found out that the authentication with Gmail was failing because PHPMailer is using port 25 by default (and Gmail’s SMTP does not) and I wasn’t using SSL or TLS encryption for the authentication. I found a solution here, and it solves the problem by adding two lines of code (specifying the port and protocol of the connection) to PHPMailer’s class.smtp.php. Nice, simple and most importantly - works !

I was looking for a flexible and user-friendly CMS to use in a project I am doing for Ardent Interactive. My prime candidate was Wordpress until I was referred to the website of a CMS I had never heard about - Silverstripe. It’s an open-source CMS written in PHP and offering a flexible MVC development framewrok called Sapphire. One can easily extend and improve the core functionality of the CMS by making use of the modular architecture of the framework for developing modules and widgets. Silverstripe’s community is still small and there is a limited number of skins, modules and widgets available for download, but I believe they’re on the right way and many developers will soon join their efforts.

I just uploaded some stuff to the Downloads section. They’re basically small home projects I’ve done rather with the intention to learn, than because I couldn’t find ready solutions.

After about a year, I finally took some time to put a little info out here on tishon.net. I’ve been postponing the launch of this blog for quite a while and I’m happy I finally did. There’s almost no info here right now, but, as we say in Bulgaria, “good things happen slowly”.
