Of course this post is talking about hard disks. The ones with spinning disks and read/write heads flying very close to the spinning disks surface.
There are several links to the source papers and works discussing the findings – take look into this nice rabbit hole:
Posting this here, better late than never:
“Shepard’s Pi” is one continous song that lasts for 999,999,999 hours, or about 114 years.
Canton Becker’s music generating algorithm composed this music using the first one billion digits of pi (p). Each digit (3.1415…) determines four seconds of music, supplying the “turn signals” used to determine every musical expression.
Because the numbers in pi never repeat, each of the million hours of “Shepard’s Pi” music are in fact unique. By fast forwarding to some distant moment in the song, you are virtually guaranteed to find yourself listening to something that nobody else including Canton himself has ever heard before.Shepard’s Pi

I gave Rifftrax a swing in 2006 when they started their project. Now it’s time for a revisit.
Rifftrax was created by the same people that created and made the series “Mystery Science Theater 3000” so successfull.
Think of this: You go to the movies. Bad movies mostly. And there are 3 of your friends next to you and constantly commenting the movie – in a funny way.
Since MST3k had ended a long long time ago the people behind it have started to do the same with current movies. And this they called “Rifftrax”:
Mike Nelson, Bill Corbett and Kevin Murphy, the former stars of Mystery Science Theater 3000, create commentaries for B-movie oddities and Hollywood blockbusters. It’s like watching a movie with your funniest friends!
Their catalog has grown from 0 in 2006 to over 222 full length feature movies and much much more shorts.
If you have never experienced their art: Give them a try. You’ll probably laugh a lot!
Collection of 8000+ publicly available IPTV channels from all over the world.
Internet Protocol television (IPTV) is the delivery of television content over Internet Protocol (IP) networks.Github: iptv-org/iptv
Using the streams is as simple as it gets: Just open the provided playlilst files in your favorite media player. The above example is th VLC media player.
As iOS 13 has introduced a system wide dark mode into my workflow I had a good reason to give the CSS of this website a little spin.
Depending on your system settings this website now supports Dark Mode.
I am running most of my in-house infrastructure based on Docker these days…
Docker is a set of platform-as-a-service (PaaS) products that use operating-system-level virtualization to deliver software in packages called containers. Containers are isolated from one another and bundle their own software, libraries and configuration files; they can communicate with each other through well-defined channels.
All containers are run by a single operating-system kernel and are thus more lightweight than virtual machines.Wikipedia: Docker
And given the above definition it’s fairly easy to create and run containers of things like command-line tools and background servers/services. But due to the nature of Docker being “terminal only” by default it’s quite hard to do anything UI related.
But there is a way. By using the VNC protocol to get access to the graphical user interface we can set-up a container running a fully-fledge Linux Desktop and we can connect directly to this container.
I am using something I call “throw-away linux desktop containers” all day every day for various needs and uses. Everytime I start such a container this container is brand-new and ready to be used.
Actually when I start it the process looks like this:
As you can see when the container starts-up it asks for a password to be set. This is the password needed to be entered when the VNC client connects to the container.
And when you are connected, this is what you get:
I am sharing my scripts and Dockerfile with you so you can use it yourself. If you put a bit more time into it you can even customize it to your specific needs. At this point it’s based on Ubuntu 18.04 and starts-up a ubuntu-mate desktop environment in it’s default configuration.
When you log into the container it will log you in as root – but effectively you won’t be able to really screw around with the host machine as the container is still isolating you from the host. Nevertheless be aware that the container has some quirks and is run in extended privileges mode.
Chromium will be pre-installed as a browser but you will find that it won’t start up. That’s because Chromium won’t start up if you attempt a start as root user.
A friend of mine started something and I have the honor to be part of it. The world now has one additional podcast to listen to. It’s in german though. For now at least.
We are still working on the website, the feed and the audio mixing and recording quality. So bear with us.
And now: Episode 0 is upon us!
There are many connectors out in the world. A lot of them are old but get still used. And once every while you might need an actual great drawing / scheme of such a connector.
There’s a place for all your needs and curiosity. It’s bitsavers.org.
Just take a look at this drawing and cut-away of a coax connector from the 1976 AMP product catalog:
There is lots more, just take a look at bitsavers. Especially the software bits archive of (very) old computers software and sources. Just wow.
The firecracker exploded. Apparently after 2 weeks of usage of the Chuwi Hi10 Air the eMMC flash is malfunctioning.
In a totally strange way: Every byte on the eMMC can be read, seemingly. Even Windows 10 boots. But after a while it will hang and blue screen. Apparently because it tries to write to the eMMC and when those writes fail and pile up in the caches at some point the system calls it quits.
Anyhow: It means that no byte that is right now on this eMMC can be deleted / overwritten but only be read.
The great chinese support is really helpful and offered to replace the device free of charge right away. That’s very nice! But I came to the conclusion that I cannot send the device in, because:
It contains a full set of synched private data that I cannot remove by all means because the freaking soldered-on eMMC flash is broken.
The recipient of this broken tablet in china would be able to read all my data and I could not do anything about it.
Only an extremely small fraction of data is on there unencrypted. Only that much I hadn’t yet switched on encryption on during the initial set-up I was still doing on the device. And that little piece of data already is what won’t let me send out the device.
Now, what can we learn from this? We can learn: Never ever ever work with anything, even during set-up, without full encryption.
…in July takes 27.1 days, covering 2967 kilometers. At least if you would have taken the challenge in times of the Roman Empire.
ORBIS: The Stanford Geospatial Network Model of the Roman World reconstructs the time cost and financial expense associated with a wide range of different types of travel in antiquity. The model is based on a simplified version of the giant network of cities, roads, rivers and sea lanes that framed movement across the Roman Empire. It broadly reflects conditions around 200 CE but also covers a few sites and roads created in late antiquity.ORBIS: The Stanford Geospatial Network Model of the Roman World
By simulating movement along the principal routes of the Roman road network, the main navigable rivers, and hundreds of sea routes in the Mediterranean, Black Sea and coastal Atlantic, this interactive model reconstructs the duration and financial cost of travel in antiquity.
Addition: Of course the app I am using is called runkeeper yet I am mostly doing cycling. On average I am actually doing about 30km every day right before work starts. Here’s an additional statistic just for cycling:
The Chaos Communication Camp is an international, five-day open-air event for hackers and associated life-forms. It provides a relaxed atmosphere for free exchange of technical, social, and political ideas. The Camp has everything you need: power, internet, food and fun. Bring your tent and participate!CCCamp 2019 Wiki
It has been 2005 that I had the time and chance to attend an international open-air meeting of normal people. Of course I am talking about the 2005 What-the-hack I wrote about back then.
This year it’s time again for the Chaos Communication Camp in Germany. Sadly still I won’t be attending. Clearly that needs to change with one of the next iterations. With the CCC events becoming highly valuable also for families maybe it’s a chance in the future to meet up with old and valued friends (wink-wink Andreas Heil).
The Chaos Communication Camp (also known as CCCamp) is an international meeting of hackers that takes place every four years, organized by the Chaos Computer Club (CCC). So far all CCCamps have been held near Berlin, Germany.
The camp is an event for providing information about technical and societal issues, such as privacy, freedom of information and data security. Hosted speeches are held in big tents and conducted in English as well as German. Each participant may pitch a tent and connect to a fast internet connection and power.
Enjoy the intro-movie that has just been made available to us, alongside the whole design material:
The Android tablets I am using for my kitchen scale display and for myfitnesspal data-entry are aging quite bad and apart from the near-display death of one of the tablets both are not supported and updated anymore.
Using them therefore poses an increasing risk. After one of them almost died on me I was determined to replace them both. Looking at alternatives at the lowest possible price quickly showed that I am not going to get another Android tablet.
Instead I was ready to give a chinese company a chance:
I ordered it on 24th of June and it was delivered today. All in all I’ve paid 136 Euro for the tablet and 45 Euro for the keyboard attachement.
Despite the ridiculously low price this thing is quite impressive. It’s sporting a fast-enough Intel Atom processor with 1.4 ghz and 4 Gbyte of RAM. The 64 Gb of solid-state storage where quickly upgraded by an additional 400 Gb MicroSD card for local data storage.
As of writing this it’s still installing and updating the Windows 10 to 1903 but so far I am beyond impressed.
I’ll write more about the device when I’ve had more time to use it. One word for the keyboard attachement: the keyboard is good-enough. Not great but better than for example that on the Pinebook. The touchpad is very small but works – the thing has a Touchscreen anyway.
The first device in my household recently has updated itself to the newest Windows 10 1903 build.
On the very first moment of the login screen appearing and logging in I could tell that I hate one specific change that has made it into this latest update.
And it’s the default mouse cursor.
Back in the Pre-Windows Vista days, when I used to work for Microsoft, I was using the latest internal build of Windows and just around the first RTM (release-to-manufacture) build they touched up on the final designs.
I remember vividly when the mouse cursor had changed from the one we new and used since Windows 3 to a shorter tailed more “high-def” looking one.
Since then there were a couple of changes on the cursor but the general design was kept.
Now apparently with the latest Windows 10 update from 1803 to 1903 I got a new – old default mouse cursor.
By reflex I changed it back to the one I love and stored safely in a backup. I cannot stand the long tail and the weird pixel-ness of the cursor. It just looks kinda weird to my eyes.
Which one do you like better?
When you walk around in Tokyo you will find that many buildings have red-triangle markings on some of the windows / panels on the outside.
I noticed them as well but I could not think of an explanation. Digging for information brought up this:
Panels to fire access openings shall be indicated with either a red or orange triangle of equal sides (minimum 150mm on each side), which can be upright or inverted, on the external side of the wall and with the wordings “Firefighting Access – Do Not Obstruct” of at least 25mm height on the internal side.Singapore Firefighting Guide 2018
The red triangles on the buildings/hotel windows in Japan are the rescue paths to be used in case of fire. All fire fighters know the meaning of this red triangle on the windows. Red in color makes it prominent, to be located easily by the fire fighters in case of a fire incident. During a fire incident, windows are generally broken to allow for smoke and other gases to come out of the building.Triangles in Japan
Hmm… I’ve set-up a script to automatically download a TV show about a year ago and just remembered it…
Apparently 1 year of this show is 167 Gbyte…
For completeness the download script – ignore my bad scripting:

Try to wrap your head around this: There are people out there that take the term “Maker” to new levels. People Like Sam Zeloof. He went out and created his very own integrated circuit designs and then he built them. Like the actual silicon, the die, the bonded chip, the IC. The real thing.
I am very excited to announce the details of my first integrated circuit and share the journey that this project has taken me on over the past year. I hope that my success will inspire others and help start a revolution in home chip fabrication. When I set out on this project I had no idea of what I had gotten myself into, but in the end I learned more than I ever thought I would about physics, chemistry, optics, electronics, and so many other fields. Furthermore, my efforts have only been matched with the most positive feedback and support from the world; I owe a sincere thanks to everyone who has helped me, given me advice, and inspired me on this project. Especially my amazing parents, who not only support and encourage me in any way they can but also give me a space to work in and put up with the electricity costs… Thank you!Sam Zeloof
Seemingly short-message services are becoming the standard mode of communication for the powerful and rich. It seems that especially Twitter is capable of bringing the worst in those among us to the outside.
Of course the most controversial statements are being washed away by the sheer throughput. The next one always comes up quicker than you expect.
Helping the masses to keep track is a main task of journalism. That being said traditional journalism (as in newspapers, television) sees great difficulties to keep track as well. Too much, too quick.
So new forms of journalism develop. Often more tendentious then helpful for the cause so they require the cautious mind of the reader to add some more perspective.

drop in replacement for tail -F that asks you if you are still watching
Just like Laura I am also was having a moment when I stumbled across tailflix.
For those not understanding the reference: At the end of an episode you’ve watched on Netflix you will be shown another one, and so on, and so on. Until if you have not touched the remote at all for several episodes Netflix will ask you “Are you still watching?”.
