At the beginning of this year, we threw away many boxes
full of VHS cassettes, with films and series we recorded via cable TV, mostly over two decades old. I was reminded of fun movies like "Men in Black" with Tommy Lee Jones and Will Smith from 1997. But my mom pointed out "In der Arche ist der Wurm drin", a German cartoon by Wolfgang Urchs from 1988 i almost forgot, but still had somewhere in a corner of my memories
. Now, weeks later, it was bothering me, not being able to remember the storyline. I had to search for it, without even to know the exact title, since it was only handwritten in Chinese on the label of the VHS.
But i found a copy on YouTube. Sadly, in a really bad quality. Still, better than nothing. Back then
, i watched it as a child a couple of times, which introduced me to the story of "Noah's Ark" for the first time. Watching it after all these years, i realized how some things don't age well, but make you appreciate them anyway, because they influenced me
somehow at sometime. The cartoon tried to communicate some "christian values" by spinning it to something more entertaining, which was not clear to me as a kid. In some way, this reminds me now of Johnny Five, and to download the movies "Short Circuit" (1986) and "Short Circuit 2" (1988) from my childhood, next time, when i get the chance
Since July 2017, i have my first one running "motionEyeOS" as a CCTV camera on a regular basis. Two weeks ago, i even built a custom UPS for it, also known as "Uninterruptible Power Supply", to make it somewhat independent
from a power source. The "off-the-shelf" parts for this project were a 5V relay module with "low level trigger", charging module with "battery protection", boost converter, and 3300uF 6.3V capacitor, which results in a much cheaper solution than a Adafruit Powerboost 1000C.
My second and last Raspberry Pi Zero W runs since January of this year permanently too, but with a much wider range of tasks
. I already got it to break down several times, by giving it more load than it can handle, which is not that difficult, since it has only a single-core CPU at 1 GHz and 512 MB RAM. But finally, i got it under control
by giving every job only a certain time span to do its thing, just like shift work. And the built-in hardware "watchdog" tries to keep it all going by checking the heartbeat of the software.
For example, it takes with "raspistill" and the camera module one photo every 60 seconds, and it pauses twice each hour for ten minutes, as instructed in my shell script. Because the task is not mission critical
, since it's just looking out the window and collecting images of a castle nearby. The given silent period is the chance for "FreshRSS" to check feeds for updates every half an hour. My Perl script tries to get new content
for my parents from the BBC server every 30 minutes too. Occasionally, i also use it to develop and test new things, which can tear it down completely, or even corrupt the microSD card, if i forget to put all the code i have running to sleep.
In the two decades that i have been doing things on the internet, i have used many web hosts such as FortuneCity, Schlund+Partner, Strato, and 1und1. They were all good at the time i went to them to host my projects
. They made my time easier by not having to worry about the technology behind the server. But eventually the performance was no longer adequate, and i had to move on. As you know, i downsized my webspace
at the beginning of this year. But apparently the Friedersdorf based web hosting service "ALL-INKL" can’t handle my traffic and load at that price point, which is why i went to Amazon AWS and created a "Lightsail" instance for less money, but more performance.
Since i already had experience with running a Apache web server on Linux-based Debian and a headless Raspberry Pi
, it was simple to set everything else up. After some hiccups with Ubuntu and an old LAMP stack, i got it all working. On the surface, it looks like nothing happened, but behind the scenes
i changed many parts to make it appear like that. For example, i had to set up Cloudflare as DNS and Mailgun as MX record for some of my domain names, to make them keep pointing to the right direction. I also removed the logging of IP addresses to comply with GDPR.
Many years ago, i built and run a blog hosting service for a long time
, among other things, like embeddable chat widgets. All written in Perl, from the very bottom, and without any framework. I learned a lot, during and after it. I became quite good in handling file-based databases, even with thousands of hits per hour, because of the techniques i developed to prevent too much load on the server. Later, i installed WordPress for publishing my own posts
, instead of writing my own code in Perl. Because why reinventing the wheel, if no one cares anyway?
But i was never a PHP and MySQL person, because of the many external dependencies, which is why i now took the opportunity to write a "flat-file based blog" from scratch, just in case if i ever need to move somewhere else again, so i don't need to fumble around
with things i don't enjoy, or don't have time for. FYI, the rooms in our rented apartment have on average three clocks, in almost every direction at least one, because my dad likes it. All pages here are now static HTML files, which were generated by a dynamic Perl CGI script i wrote.
Last year, i used a similar title
for a post on the blog, but on this occasion, i travelled back in time by cleaning up the living room with my parents. In late 2017, our landlord motivated us to do this, because to him it looks dangerous
, having mountains of seemingly random things in a place, where normal people watch TV or play board games
with friends. But we don't have much time for that, since we have to pay for rent, food, healthcare, public broadcasting, and everything else. Welcome to the bottom of this pyramid scheme.
The origin of most stuff
in the living room is "life". I moved twice with my parents, and each time we kept most of our belongings, because everything is precious to us, since we are not smart, or rich. Nevertheless, we are not keeping highly combustible objects around. Back then, in 1992, we run our Restaurant in Ratingen
for many years, where my father cooked in the kitchen with heavy "woks" over real fire, without anything bad happening.
But since our neighbours in Bad Godesberg
might not be as thoughtful as we are, i do understand the danger of having too many things around. For example, the way they handle garbage bags or how they close apartment doors is a nightmare. And thanks to their habit to let the house door wide open, i got my MiniDisc recorder and my mountain bike stolen. This is why we now have a basically normal living room, just in case they start a campfire indoors, or some accident happens. After all, no one is perfect, except maybe Julia Roberts
. By sorting through all the old stuff, i occasionally get surprised, because things are getting new perspectives to look at. It's like being in a history museum
and wandering around in the past.
For example, i found a lot of "Colleen Colored Pencils" my aunts and uncle sent me from Hong Kong
to Germany, over 20 years ago. I was probably anxious to use them, since they are really special to me. This is why i have several packages full of new stationeries waiting to meet a piece of paper. I already doodled a couple of "Stargates", inspired by the TV series
, and uploaded them to YouTube. My mom also found my over 15 years old "Hohner Echo" harmonica again, and i made it a part of some videos.
In April 2012, i signed up for Amazon Prime Student, because officially i was still a geography student
at the University of Bonn. Back then, there was no video streaming available. But the fast and "free" shipping was already worth the discounted price. Later, in early 2014, they introduced Prime video in Germany including a limited selection of movies and shows, which made me keep being subscribed to it. But in the past months, i basically stopped shopping on Amazon
, because of Aliexpress. Things are taking a lot longer to deliver, but the prices are hard to beat.
Now, in February 2018, Amazon sent a Email telling me they will upgrade me to "regular" Prime without discounts, which makes it all even less compelling, since i have already seen many
of the contents in their video catalog. And in Mai 2016, i discovered BitTorrent "in the cloud", which opened a door to new options, next to Prime video. It's safer than a standard setup, where you run everything local, because the BitTorrent client
here is not directly installed on the computer. In December 2015, i got to try Netflix too, which i had for one month as a free trial. FYI, my first order on Amazon was in October 2006, and i bought a Sony ICD-SX56 digital voice recorder for capturing audio at university.
