2019-09-08: Today, I Am Tweeting for Ten Years

Ten years ago, I started using Twitter for micro-blogging. It was an experiment, mainly to find out why people are using this media and see how my opinion changes when using it. At first, I was quite sceptic.

2019-08-29: The Cost of Switching Software Tools

Jack Baty (yes, the guy from this article) wrote an interesting blog post on the reasons why he is switching his tools:

I do like to try new things, and if I’m being honest, there are only 3 reasons I switch tools:
1. Boredom 2. Procrastination 3. Curiosity
Everything else is rationalization.

Interesting. My situation and opinion is different.

2019-08-25: Japan - First Impressions from an European Point of View

My wife and I have been traveling through Japan for two weeks: Tokyo, Fukuoka, Osaka. This is not a report on our trip. This posting is a mixed, incomplete and subjective collection of stuff that we found cool, exaggerated, quaint or just different from our situation in Austria (Europe).

2019-08-25: Buch-Kritik: »QualityLand« von Marc-Uwe Kling

Schon 2018 stolperte ich nach deutlichen Empfehlungen über das Video von 34C3 von Marc-Uwe Kling, wo er eine Lesung mit Textausschnitten aus seinem Buch "QualityLand" hält. Ich habe nach dem appetitanregendem Video nicht gleich das Buch besorgt und es wieder aus den Augen verloren. Vor kurzem habe ich es von Freunden empfohlen bekommen und gelesen.

Gleich mal vorweg mein Fazit: absolute Pflichtlektüre für alle!

2019-08-12: Contributing to Openstreetmap and Mapillary

I was travelling some cool locations in Asia. When I was using OsmAnd to navigate, track and looking for restaurants and shops, I noticed that in my area, most restaurants and shops were not mapped yet. Further more, I saw that there was no Mapillary-based photos available. Mapillary is a cool alternative to Google's Street View, if you don't know it yet.

This was where I decided that I could improve the situation a bit. And it was that easy that anybody can do it as well.

Update 2018-07-22: moved folder hierarchy explanation to an article on its own

Update 2019-07-09: Email comment on genealogy and characters to avoid in file names

I am a passionate photographer when being on vacation or whenever I see something beautiful. This way, I collected many JPEG files over the past years. Here, I describe how I manage my digital photographs while avoiding any vendor lock-in which binds me to a temporary solution and leads to loss of data. Instead, I prefer solutions where I am able to invest my time and effort for a long-term relationship.

This (very long) entry is not about image files only: I am going to explain further things like my folder hierarchy, file name convention, and so forth. Therefore, this information applies to all kind of files I process.

Before I start explaining my method, we should come to an agreement whether or not we do have the same set of requirements I am trying to match with my method. If you are into raw image formats, storing your photographs somewhere in the cloud or anything else very special to you (and not to me), you might not get satisfied with the things described here. Decide yourself.

2019-07-09: Poor Man's Monitoring of a Remote Linux Host via Syncthing


I'm helping some old lady by administrating her notebook. I set it up with Xubuntu LTS GNU/Linux which comes with the very easy to use and fast Xfce environment: not bloated and offers everything necessary. I stripped down the "start menu" such that it only shows the ten apps she's using.

Remote access is done via TeamViewer if necessary.

Today, I set it up with a neat monitoring I'm going to explain in this post.

2019-07-06: Why We're Going to See Only Clickbait Titles and Thumbnails in Future

Derek Muller who is doing the Veritasium YouTube channel has published this video.

I did not know him or his videos before but he is a magnificent example of how to present things in general. He has written a PhD thesis on this topic.

In the video mentioned above, he is explaining how you can influence if your video is going viral. He further explains that some YouTube stars do face some issues in keeping their view counts resulting in burnout effects. He found out that the viewers over time of a YouTuber channel follows a specific function, which is a very interesting discovery if this holds true for a large number of YouTube channels.

He criticises the number of views as a measure of quality, the tiny fraction of YouTube videos that are actually pushed at all and how the designers of YouTube recommendation algorithm are actually defining what you are going to watch.

For YouTube video producers, YouTube isn't a reliable environment where you are in a position to define if your video is going to be successful or not. In this situation, YouTubers are pigeons in a operant conditioning chamber following some assumed patterns that are not related to the end result, causing burnout effects.

He further explains that YouTube is moving from a subscription model to a kind of yellow journalism where clickbait titles and catchy thumbnail previews are a must. This is actually the opposite direction how journalism developed and was able to provide high-quality content.

It all boils down to maximizing watch time and click-through rate.

He further extrapolates the current situation for the media in future. Not to spoil his insights to much: this is not going to be better. On the other hand side, he is also proposing a way out of this situation in order to create a better future.

Watch it yourself.

2019-06-12: Jonathan Blow: Preventing the Collapse of Civilization

Jonathan Blow gave a talk at the DevGAMM 2019 conference in Moscow about Preventing the Collapse of Civilization (YouTube):

You can read some interaction between Jonathan and a few people on Twitter in the thread of this tweet:

Here's an upload of my recent talk,
"Preventing the Collapse of Civilization",
given at DevGamm in Moscow.

This one is English audio only, fixing the unlistenability of the post-stream recordings.
Hopefully there will be a Russian-only as well.

— Jonathan Blow (@Jonathan_Blow) May 18, 2019

If you skip all the references to game development, this talk is really something that summarizes many things I was thinking myself before. Could it be the case that there is a huge thing going on in IT where we actually face a decline of development with hardly noticing?

2019-05-31: GLT19-Talk: Freie Infrastruktur für unfreie Arbeitsplätze

Bei den Grazer Linuxtagen 2019 (GLT19) gab es einen Talk von Goesta Smekal zum Thema Freie Infrastruktur für unfreie Arbeitsplätze (Folien).

Ich habe mir nun die Aufzeichnung nachträglich angesehen:

Die erste Hälfte ist eine Motivation für den Einsatz von freier Software in Firmen beziehungsweise ebenso ein gute Leitfaden, wie man für welche Fälle besser auf freie Software setzt und wann nicht. Ich fand das Thema gut umrissen.

In der zweiten Hälfte (Q&A) erzählte Goesta frei, wie er in seinem Betrieb den Umstieg von Outlook und Exchange auf Kopano (Fork von Zarafa) geschafft hat, obwohl das eine heikle Operation war. Da ich schon mal vor vielen Jahren in einer ähnlichen Situation war, fand ich seine Ausführungen dazu hochinteressant.

2019-04-29: How Do I Profit from Free and Open Source Software? (GLT19-Talk)

At the Linuxdays 2019 in Graz I gave a motivational talk "How Do I Profit from Free and Open Source Software?" as I already announced.

It is be a motivational talk that mentions some arguments for free and open software. I tried to cover the point of views for normal computer users, companies deciding for software or source code producing persons deciding for a license model.

Due to technical issues with room speakers, the whole talk was suspended from minute 32 to 36. Please do skip the time in-between. You do not miss any content from the talk since I stopped talking until the issue was solved.

You can get the video also from the CCC media server which I recommend in contrast to YouTube.

2019-04-23: Announcement: "How Do I Profit from Free and Open Source Software?"

This Saturday (2019-04-29) at 10am, I'm going to talk about the advantages of free and open source software (FOSS) for users, companies, developers, tax payers and so forth. The talk takes place in the lecture room i1 at the Grazer Linuxtage 2019. This year, the event is located at my Alma Mater, the Graz University of Technology.

It will be a motivational talk that mentions not all arguments for free and open software but maybe some that did not cross your mind yet.

Here is the URL to the talk. There will be a video recording of my talk available at Saturday evening.

See you!

2019-04-14: Microsoft OneNote

Update 2019-04-14: Leider hatte ich früher recht als geglaubt: Microsoft gibt das "große" OneNote zugunsten der abgespeckten Version "OneNote for Windows 10" auf. Die Daten können leider nicht übernommen werden.

Microsoft lässt aufhorchen, da es Microsoft OneNote für Windows und OS X gratis weitergibt.

OneNote ist wirklich sehr gut aber leider langfristig ein absolutes No-Go. Dieser Beitrag hier erklärt weshalb.

2019-04-12: Org-Mode Is One of the Most Reasonable Markup Languages to Use for Text

Update 2017-09-25: Simplified the table syntax even more

Update 2018-04-06: Comments on the standardization argument

Update 2019-04-12: Extended syntax examples, "Makes Sense Outside of Emacs", "Tool Support" and added more backlinks

Disclaimer: this is a very nerdy blog entry. It is about lightweight markup languages and why I think that Org-mode is the best lightweight markup language for many use-cases. And with lightweight markup language, I do mean the syntax, the way you express headings, lists, font variations such as bold face or italic, and such things.

Please do note that this is not about Emacs. This is about Org-mode syntax and its advantages even when used outside of Emacs. You can type Org-mode in vim, notepad.exe, Atom, Notepad++, and all other text editors out there. And in my opinion it does have advantages compared to the other, common lightweight markup standards such as Markdown, AsciiDoc, Wikitext or reStructuredText.

Of course, Org-mode is my favorite syntax. Despite my personal choice you will see that I've got some pretty convincing arguments that underline my statement as well. So this is not just a matter of personal taste.

If you already have a grin on your face because you don't have any clue what this is all about: keep on reading. It makes an excellent example for making fun of nerds at your next dinner party. ;-)

2019-03-13: Restic Backup on Windows 10 with Babun/Cygwin

Update 2019-03-13: comments Florian.

I heard great things about restic for solving the backup requirement.

Since it does also support Windows, I gave it a try on my business Windows 10 and my babun environment, which is a user-land Cygwin with better presets.

Here are my findings.
