I first started developing web projects when I was young. First it was only
html pages with css, but later I moved to php/MySQL, php/PostgreSQL, php/SQLite
combinations. I wrote my whole personal CMS for various purposes (from blogging,
finance data statistics, user management, web-shop) during this time. It was
quite in early days of php and I was looking for a bit better solution. Soon
Django as Python framework with CMS was a viable solution
to maintain and start new web projects. As older php projects required increased
maintaining and development I have decided to use twig as template engine of choice.
browsing experience, but were later a bit replaced with html5 and css3 possibilities.
Knowledge of Google Analytics, Google AdSense, Google Webmaster Tools and other useful
Google tools was obtained while trying to monetize the projects to some extent.
Below are some still maintained projects and their specifics.
Lets start with a bit of history of current website. It is written in php with support of twig template engine and MySQL. No CMS or user management is basically needed or implemented. Simple Google Analytics with Google AdSense are added just for fun. As part of the normal development practice also LetsEncrypt certificate was added in 2018.
Rolerski klub Ljubljana webpage
Since I am founder of the Rolerski klub Ljubljana this page has served as an
learning example through time. It started as simple news website written in php
with user management to add news. Background database was MySQL. Soon expansion
begun with adding some management to create invoices and for a simple accounting
system. It is integrated with Google Analytics for detailed statistics and used
AJAX to refresh various parts of the website. Search Engine Optimization was
constantly improved, but some limitations of the core system were soon spotted.
In 2015 new more modern look was established and system migrated to Django on PostgreSQL. Google Analytics with Events reporting and loads of AJAX was perfected to my current knowledge as well as previous lessons learned were implemented. SE optimization is easier and more maintainable while still providing a decent platform for the admins to admin content. JQuery was also added to produce a more modern look.
Coloring art blog
I made a coloring-art website for my wife. Since she was learning
Django, that was the go-to tool that I used and the new technology that I tried was AMP. My
challenge was to build just one website (in AMP) for both desktop and mobile users.
With all the challenges of the AMP (webeditors in Django do not support it, forms do not support
it, mailchimp subscription does not support it) it proved to be a bad design decision.
However after more than needed struggle I got all the above working, and I have even
managed to opensource the mailchimp-amp extension for Django (probably needs some work).
Website design is quite simple, but the AMP part the made the real challenge and in background I also learned SCSS to produce nicer CSS (which is then embedded into a template because of the AMP) for the website, but the real advantage was a bit lost because of the AMP.
On the end I am proud to have produced 0 AMP error and warning website and I hope that the SEO is good enough to rank on first page on certain keywords.
Rolarska zveza Slovenije webpage
Another quick project for the association I am part of. It is a php and MySQL
project with CMS for content and user management. It is also special as it has
interface to add live results to the website while calculating scores and sorting
by time or places. System enables us to run the whole race and broadcast it live
online with same click. Printing data using A4 templates is also enabled. System
is able to track progress of members and statuses of memberships. Website is using
simple Google Analytics for user tracking.
Site still has old look and is currently pending renewal. News are updated regularly by admin base.
Also website developed to support the Rolerski klub Ljubljana main sponsor.
It needed to be online fast (time to first live version was 2 days) with basic
webshop/webinfo capabilities while providing a bit more specific CMS. It is using
quite a decent implementation of Google Analytics as well some AJAX to keep various
parts updated during the search. It has implemented SESSION cookies with some
specifics to provide seamless user interface. It also provides news with photo
uploads through admin interface where images are automatically scaled and watermarked.
Some expansion was done especially with adding Cycling section to original Inline Speed skating section, but no major redesigns have occurred.
In 2020 the website got a bit of a redesign with the AMP version available and indexed. Also everything was moved to Twig templating engine and update for php7 syntax and PDO classes for the MySQL connection.
Revija Vita online version of printed magazine
Expert health-education magazine Vita is very popular in Slovenia. The
printed version runs out fast, so the magazine has soon expanded to web. Main idea was
to keep the design of the printed version as close as possible, but to still make use of
dynamics of the web. The website is visited by between 3000 and 12000 people each day.
It is more impressive that content is exclusively in Slovenian, where overall population is
just 2 million.
Revija Vita has more than 80 official releases at the time of writing and many more are expected to come. It also has news part where important health-educational news are shared.
There was a redesign made to Twig templating engine in 2018 which improved site maintainability and expansion with additional advertising spots.
Keyword-boost.com traffic-exchange with bounce rate lowering system
There was a need to drive traffic to my sites and there are a lot of traffic
exchange sites online that allow you to visit other sites in exchange for others
visiting yours. I identified the problem that this lowers your bounce rate as visitor
basically only sees one page and leaves. Among this, these websites are also listed
as referrals on the Google Analytics, so this kind of action is easily identifiable.
Idea was born that system can first redirect to Google or any other big search engine, input keywords associated with website, then visit the website and also make another view on the website. This way referral is from search engine, and bounce rate is lowered because of the second view. It worked well, reaching over 100 active users, but search engines kept adapting the statistics and also made it illegal in their terms of service to use such techniques, so I decided to stop it and delete all account information.
Contributions to Open Source projects
For hobby I was contributing and using a lot of open source projects in the past. I never had confidence to maintain repositories or even start new ones, until I started working for Melexis. One of my tasks at Melexis is to enhance the Open Source mindset inside the company. Beside opening our tools also a lot more device drivers were opened.
I am official maintainer for MLX90614 - Melexis Infra Red Temperature Sensor and MLX90632 - Melexis Infra Red Temperature Sensor. There are some other contributions that I also made to Linux kernel and they can all be found
Private Kubernetes Cluster
I had few Raspberry Pi3 in the cupboard collecting dust, so I decided to make a Kubernetes cluster which could be used to host websites or do some computations for me. Since RPi3 is not powerful enough I added two Rasberry Pi4 (one is master and one node) to the cluster which now runs for more than a year. Whenever I have some time, I try to write, develop and port applications to this Kubernetes cluster as I think that this is the future of IT.
Private GitLab server
All the time of maintaining private web server has got me to also maintain private GitLab server where I could backup my existing projects. This has grown over time with addition of Dockerized GitLab-CI runners (Raspberry Pi Zero, Raspberry Pi3) on armhf and armlf architectures as well as huge knowledge base of tricks and pimps. Since server was regularly updated it kept me in shape with the IT practices and tricks to keep a decent availability. Because of the performance/disk space restrictions I have decided to close the GitLab server and just use public GitLab.com for future development.
Literature and references
As you can see on my blog I occasionally write something about my developer or coding experiences, but also some articles about traveling and my thoughts. This page serves mostly as my private blog and an easy followup of the solutions I have implemented for various occurring problems. It is a lot easier to search my own website than whole web again for the solution.
Due to my extensive experience with Git Version Control System, I have written an article on GitLab.com about Numerous undo possibilities in Git.
