Who am I?

My name is Harm Frielink, born in Leiden, the Net­her­lands, on August 21, 1954. I am currently living in Neuenhaus Germany with my lovely wife Riet and a pond full of flowers and frogs. Since November 2021 we have 2 you-know-what Cats Max & Sam. In short, an European pur sang.

Since September 2016 I am retired. I have worked for: Saxion, Newcom R&C, IBM, Logica(CMG), Goudse Insurance and Micropartners.
My interests in alpha­betical order are Actuarial/Math Calculations, Ancient Cities, Chess, Computers, Contract Bridge, Cycling, Formula 1, History (especially WWI), Motorbikes (MotoGP), Pop Music (Top2000), Programming, Soccer, Tennis and Wikipedia.


Sharing knowledge is crucial. I am using Mediawiki to share this know­ledge on the Internet.
Feel free to visit my internet Wiki with items on eBooks, Programming, Patterns and History (World War I).
Please note not all items on my Wiki are public (due to security).


More knowledge links to (web) applications) are mentioned below: Covid-19 Daily Country Comparison, Household Energy Maintenance, PHEV Consumption Maintenance, Keyword Links, Financial Calculator, Gamble Safe Calculator, Roulette Draws and Utilities for developers.

Application documentation

These applications have extensive online help, FAQs, which can be reached without logging. In addition, the applications have a separate manual in the wiki.
I hope you enjoy what you find here, (maybe you wanna) let me know by sending me an email.

Internet Search using Tags

How often did you search the internet and did not find previous discovered items ?
Or even more precise: How often did you search and did not find the correct answer on your search question.
If you could collect all your searches by the found results, would that make your inquiries more efficient?

Search the Internet using Keywords does exactly that. By adding metadata to search criteria makes inquiries for data more easy. The added metadata containing the searched keywords makes re-use possible. The only disadvantage: you did not make the selection, I did (since 2001).

The knowledge I added to the keywords, in other words, the metadata is of course not only of use for me but also for other users. So why don't you try Keyword Links.

Google Custom Search

Programming Computers

Computers have become a commodity product, with users on Facebook, Pinterest, Tumblr, Twitter & WhatsApp. Users who want more still need to learn a Computer Language. However writing Quality-Heavily-Visited-Secured-Websites is not that simple.
My interest has always been making (static and dynamic) Software-Quality-Controls, Modeling and How-To write Software-Documentation. My first experience with computers dates back to 1977, I have experienced the IC-innovation up close.


A Wiki is a marvelous way to collect and distribute information/knowledge. I am using it for myself and to share information with all others.
Abuse has forced me to disable contribution of unregistered people. Although I am very open minded not all info is available to everybody. See for more information my wiki HaFrWiki.


Occasionally I like to write a blog article to express my opinion. See the social media tags in the footer of this webpage.

History WWI

I have a history fascination especially for World War 1. On Flickr I have put photos of the Ypres salient, the Somme and Verdun.
On my Wiki I have started a small WWI Wiki. Please keep in mind: Photos on the Flickr/Wiki can be shocking.


Now I am retired I have time to play games, to make games and help websites. The Formula-1-Augur is a family & friend Predictor Contest for Formula-1-Races. Please join this contest and have fun.
