About

Daniel Duriš is an SEO expert, a tech speaker and a cycling advocate.

My name is Daniel Duris (nickname: dusoft) and Ambience is my blog. I started this blog in 2003 in Slovak and switched to English in 2010.

I am very keen on all internet stuff and work at Basta digital, a digital marketing agency that I co-founded in 2006. I specialize in strategic consulting, SEO, digital analytics and data integration/automation. I have extensive experience with data scraping and cleaning. I also love working with APIs.

I am also a co-founder and a former president of Cycling Coalition, an expert advocacy group that has been improving cycling conditions in Bratislava and Slovakia since 2010.

You can visit my Github repositories – I work mostly in PHP and Lua.

I am open to collaborate or work on interesting and innovative web stuff. Contact me below.

My earlier software projects

I have abandoned these for the time being.

EbookHood was a website that allowed users to share their ebooks with friends and convert it to different formats. Parts of the code were later donated to another ebook website. PC Mag featured it in its Best of the Internet column.

I created iPod eBook Creator for iPod Notes that allowed users to convert longer text and convert it to a convenient reading format for iPods. This was before there was any convenient ebook technology and addressed the 4 kb limitation of iPod Notes.

“Daniel Duris has developed iPod eBook Creator, an unofficial tool for converting text files into iPod eBooks.” (The Guardian: Will the eBook finally replace paper?, 5 Oct 2006)

“Upload any large text file to the eBook creator and it spits out a zip file. Unzip and place on your iPod.” (Lifehacker: How to make iPod eBooks, 8 Mar 2005)

This tool was very popular and got lots of mentions all over the world by O’Reilly, Jerusalem Post, Taipei Times, Make:, Engadget, Digital Bits, Digital Inspiration, Learning Path and many others.

Open source bicycle sharing system that I have co-developed. It allows anyone to launch a low-cost bike sharing system in their community or within a company or a school. It works using web, SMS or a QR code and doesn’t require any infrastructure (stations etc.).

Fly Smart was a scraping website that offered an overview of cheap flight tickets before any larger comparison tools such as Google Flights or SkyScanner existed.

Absolut Engine was an early CMS preceding WordPress by 5 years that was SEO focused and allowed plugins. It was used by hundreds of websites and also used as a base PHP framework for other projects of mine.

As mentioned by Free Software Foundation:

“Advanced news publishing system. It features 3 layer access (admin/chief/editor), article posting, editing and deleting, an image managment tool, a file manager, and an articles manager. The built-in WYSIWYG editor lets users produce XHTML 1.0 Strict compliant code via rich text editing. User can extend the package via module functionality – any required addons/plugins (modules) can be created and added to the system. Modules currently included are Discussions, Surveys, RSS Feed, Search Engine Optimization, and a message system for better communication between users.”

Digital signage for companies – running on Raspberry Pi and integrating data from external systems.

EIA Scraper – European Union Environmental Impact Assessment project scraper, processor and notifier for Slovakia.

Bicycle count – a helper for traffic counting. It generates easy-to-print PDFs that traffic counters can use to mark down observed data. It takes a CSV/TSV file and generates a PDF/table with all directions for easy counting.

Air Quality Monitor – Open source air quality monitoring based on Luftdaten open source sensors.

Games

I have released only a couple of games. All others are just prototypes or demos.

I have been working on and off on a boat arcade called Captain Babusa in Mauritius (working title) in LÖVE/Lua.

Journey to India was going to be an Oregon Trail-like game in LÖVE/Lua featuring Indian hand-drawn public domain illustrations from New York Public Library collections.

Mystery of Disappearing Stairs was an experiment with hyperlocal geo-fenced reality game written in HTML/CSS/Javascript as a progressive web application.

I wrote a short text adventure (interactive fiction) titled Pali Teskobar in Choice Script/Javascript released for transmedia experience along a book of poetry and fiction.

I developed an urban transport simulation game written in Lua / LÖVE framework with goal of teaching players to manager transport and introduce traffic regulations for livable city (working demo).

I worked on the Political system political simulation and story telling engine written in Lua / LÖVE framework (working demo).

There have been bunch of other games I wrote – mostly text adventures – that were popular in the interactive fiction community in Czechia and Slovakia in the 1990’s.
