celebrate the discordian holyday: Chaoflux

allow me to explain by quoting wikipedia:

Dicordianism is a paradigm based upon the book Principia Discordia, written by Greg Hill with Kerry Wendell Thornley in 1963, the two working under the pseudonyms Malaclypse the Younger and Omar Khayyam Ravenhurst.

According to its primary historian, Adam Gorightly, Discordianism was founded as a parody religion. Many outside observers still regard Discordianism as a parody religion, although some of its adherents may utilize it as a legitimate religion or as a metaphor for a governing philosophy.


The Principia Discordia, if read literally, encourages the worship of Eris, known in Latin as Discordia, the goddess of disorder, or archetypes and ideals associated with her. Depending on the version of Discordianism, Eris might be considered the goddess exclusively of disorder or the goddess of disorder and chaos.

Both views are supported by the Principia Discordia. The Principia Discordia holds three core principles: the Aneristic (order), the Eristic (disorder), and the notion that both are mere illusions.

Due to these principles, a Discordian believes there is no distinction between disorder and chaos, since the only difference between the two is that one refers to ‘order’.

This is likely a major reason for the inconsistency in the wording. An argument presented by the text is that it is only by rejecting these principles that you can truly perceive reality as it is, chaos.

And given that information you can expect a discordian calendar to exist. This calendar defines years (YOLD = year of our lady of discord) and seasons and days. And holydays:

Chaosflux is a Holyday of the season of Chaos. It is celebrated on Chaos 50 (Discordian calendar) or February 19 (Gregorian calendar).

Very little is known about this holyday. What we do know is pretty much made up as we go along.

So now back to the holyday itself. How would you celebrate such a distinguished day?

I will use the services of theuselessweb.com to click 5 times on their most interesting button and then meditate on what comes up:

active noise cancellation does not suck on your eardrums

If you ever traveled on a train or plane with good active noise cancellation headphones you might agree how much more pleasant the trip was with much less noise reaching your ears.

When I tried active noise cancellation for the first time I had that weird sensation as if the pressure around suddenly changed. Like being in a very fast elevator or going for a quick dive. It felt weird but luckily it went away and the aww of joy replaced it. Quietness. Bliss.

Now there seem to be people for whom that feeling won’t go away. They get headaches and cannot stand the feeling when using active noise cancellation.

I’ve never had any explanation to this phenomena – until now. I ran across an article on SoundStage describing that in fact the feeling is not caused by actual changes of pressure but…

According to the engineer, eardrum suck, while it feels like a quick change in pressure, is psychosomatic. “There’s no actual pressure change. It’s caused by a disruption in the balance of sound you’re used to hearing,” he explained. 

eardrum suck – the mystery solved

Aha! The brain gets confused by signals reaching your ears that naturally would not exists. Those signals make no sense so the brain tries to make sense of it. And voilá something is sucking your ear drum!

sakura season forecast

I am visiting Japan for almost 7 years now but I’ve never actually been there when the famous cherry blossom – or sakura – was in full force.

As every year there’s a forecast map for this years season and it gets updated frequently:

power consumption after the ssd swap

A week after swapping out mechanical hard drives for SSDs it’s time to look at what it meant in the longer run for the power consumption of the server.

15 watt less at least

Depending on what the server is asked to do – high or low cpu load and so on – the power consumption fluctuates but it’s very visible that the averages are about 15 watt lower at all times. Great!

Apple Airplay for SONOS (in Docker)

We’ve got a couple of SONOS based multi-room-audio zones in our house and with the newest generation of SONOS speakers you can get Apple Airplay. Fancy!

But the older hardware does not support Apple Airplay due to it’s limiting hardware. This is too bad.

So once again Docker and OpenSource + Reverse-Engineering come to the rescue.

AirConnect is a small but fancy tool that bridges SONOS and Chromecast to Airplay effortlessly. Just start and be done.

It works a treat and all of a sudden all those SONOS zones become Airplay devices.

There is also a nice dockerized version that I am using.

Japan related YouTube channels I regularly watch

If you ask me for an estimate on the main sources of entertainment we use in our household I would say it’s easily 80% YouTube these days. Mainly we’re watching the content created by small independent content creators while working out or during dinner.

None of this consumption is through the YouTube website or any official clients (like the abomination pre-installed on the TV) but through a carefully handcrafted series of scripts that watch certain playlists and download everything appearing new there automatically to the house in best quality. This then can be watched at any time from any TV in the house.

The playlists that are being monitored are either those directly curated by the YouTube channels or a playlist that get’s filled directly by us from recommendations / social media links.

So here are some recommendations from our heavy-rotation list:

Some more “special ones” – Musashi-Kosugi Station is the station at my preferred home-base when in Tokyo. I like the more off-the-center vibe of Musashikosugi and this is the main station live cam there:

This would not be a complete list without this: Nippon Wandering TV is one of several channels that do one thing: walk or cycle through Japan and record it. Simple, eh? – This stuff is playing as “screensaver” on every screen in the house when not used to watch anything else:

waking up to another dying hard disk – upgrade time!

At our house I am running a medium-sized operation when it comes to all the storage and in-house / home-automation needs of the family.

This is done by utilizing several products from QNAP, Synology and a custom built server infrastructure that does most of the heavy-lifting using Docker.

This morning I woke up to an eMail stating that one of the mirrored drives in the machine is reporting read-errors.

Since this drive is part of a larger array of spinning-rust style hard disks just replacing it would work but due to the life-time of those drives I am not particularly interested in more replacing in the very near future. So a more general approach seems right.

63083 lifetime hours = 2628 days = 7.2 years powered up

You can see what I mean. This drive is old. Very old. And so are its mates. Actually this is the newest drive of another 6 or so 1.5TB and 1TB drives in this array.

Since this redundant array in fact is still quite small and not fully used as most storage intensive non service-related disk space demands have moved to iSCSI and other means it’s not the case anymore that so many disks, so well redundant with so little disk space are needed anymore. Actual current space utilization seems about 20% of the available 2TB volume.

Time for an upgrade! Taking a look in the manual of the mainboard I had replaced 2 years ago I found that this mainboard does have dual NVMe m.2 ports. From which I can boot according to that same manual.

So I thought: Let’s start with replacing the boot drives and the /var/lib docker portions with something fast.

To my surprise Samsung is building 1 TB NVMe M.2 SSDs to a price I expected to be much higher.

Nice! So let me reeport back when this shipped and I can start the re-set-up of the operating system and docker environment. Which by all fairness should be straight forward. I will upgrade from Ubuntu 16.04 LTS to 18.04 LTS in the same step – and the only more complex things I expect to happen is the boot-from-ZFS(on Linux) and iSCSI set-up of the machine.

If you got any tips or best-practice, let me know.

I just have started the catch-up on what happpened in the last 2 years to ZFS on Linux. My initial decision to use Linux 2 years ago as the main driver OS and Ubuntu as the distribution was based upon the exepectation to not have this as my hobby in the next years. And that expectation was fulfilled by Ubuntu 16.04 LTS.

The band bis is back!

One of the great pop bands of my youth are back in business and they are going to release a new album after a (too) long while! I’ve written about them in the past here and here and here…

That’s really good news for the start of the year and in fact the first new song they released today comes with good vibes end-to-end!

“2018 sees the band finally back in the studio and signed to homegrown label Last Night From Glasgow. With new songs slowly creeping into the live set and becoming fans favourites in waiting, the infamous punk/disco heartbeat may be due another lease of life yet.”

Of course todays new pop songs need a fancy new video:

Instagram – until now

I’ve had already added a couple of pictures to my instagram account – mainly while abroad. Pictures that I consider nice enough to be shared.

Of course my latest switch away from those public silos will include having those pictures posted mainly on this website and maybe as a side-note on those services as well.

To begin with I will have a separate page created that will host those pictures I consider nice enough to be shared.
