solutions not code

Retrospective view at 2018

Written by  on February 1, 2019

The first month of 2019 already passed. And we passed it with flying colors!
But let’s have a look at 2018 – a year full of challenges and success: I’ve worked full-time, organized and participated in advanced courses for Python and in Requirements Engineering (officially: IREB Requirements Engineering Foundation Level-approved) and pursued a new employment as software engineer.

And I wrote some software in my spare-time, as you can see in the graph for the public github-repositories. The gaps in the commits can be explained with the birth of my daughter and the time where I acquired the new job and moved nearly 900 km across the country. Yay! Nice personal projects were and are Cullendula and the Daily Coding Challenges, which I solve mostly with fully Unit-tested Python (3).

More new, hands-on knowledge was gained in the area of CMake and Qt-charts.
Well – 2018 was great. Let me make 2019 greater! 💪

business card: put everything technically possible in the balance

Written by  on May 8, 2018

Some weeks ago I thought that it would be nice to have some business cards and then I started to think about the data I want to share, the design and what could underline my claim to be above-average?

A paper-card with all data: standard.
Adding QR-codes to lead the user to my homepage: nice.
Adding another, bigger QR-code to the back to give him all the aforementioned data plus address: better.
Putting a NFC NTAG216-sticker on the back which delivers on reading ALL information with the slightest effort: my level!

And yes, I think you noticed my pride. I am pleased with the result 🙂

hint: created the QR-codes with the help of QR-monkey – well designed and comfortable to use

Create and maintain a shared, secure (family)-chronicle

Written by  on April 26, 2018

When my daughter was born, I thought already for a longer time about how to set up a:

  • shared,
  • secure,
  • remote-accessible platform to add stories, facts, media(!)
  • which are more or less automatically time-stamped.

We wanted to save the current steps of firstborn’s development, but not hand over the control of the data to a company. So external providers – even when they promised to be secure and safe – were out of question.
Drawn by the experience with some wordpress, which I had set up on the Synology NAS, which was first more and later less frequently used due to the quirky access to write entries and upload media, I decided against another microblog.
Of course, I even wrapped my mind around the idea of “what would be necessary to write an Android-app which synchronizes against my own server(s)”.

And then it hit me: just (ab)use the group-chat-functionality of one of the already used, secure messengers!
Data is immediately shared; it is secure due to the API-changes two years ago; it is possible to export the chronicle (with all the media); we can even alter it (remove unwanted entries); it is time-stamped;
and it costed me just two minutes to set it up!

(By the way: we chose out of the two candiates we use (Signal and WhatsApp) WA).
(I avoided the use of timeline to prevent the invocation of some weird social media-thoughts ..).

The reader may ask himself now: Ok, so why the entry? Nothing created, nothing implemented?
But I present this as one of the best examples of how to avoid to re-invent the wheel, something I’ve seen so often in my career. People start to re-implement given functionality from libraries just because they want to avoid the include or because they want to do it themselves (better).
But most often it is not about the LoC, but about providing usable, easy solutions. We* don’t have the time to do everything with our own hands if we want to be magnificent.
