Calling Bullshit

The world is awash in bullshit. Politicians are unconstrained by facts. Science is conducted by press release. Higher education rewards bullshit over analytic thought. Startup culture elevates bullshit to high art. Advertisers wink conspiratorially and invite us to join them in seeing through all the bullshit — and take advantage of our lowered guard to bombard us with bullshit of the second order. The majority of administrative activity, whether in private business or the public sphere, seems to be little more than a sophisticated exercise in the combinatorial reassembly of bullshit.

We’re sick of it. It’s time to do something, and as educators, one constructive thing we know how to do is to teach people. So, the aim of this course is to help students navigate the bullshit-rich modern environment by identifying bullshit, seeing through it, and combating it with effective analysis and argument.

Rifftrax revisited

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!

Magnificent app which corrects your previous console command

We all know this. You typed a loooong line of commands in your shell and you made one typo.

That’s the worst.

Now. There’s a command that aims to help:

It is rather simple. But extremely effective.

The Fuck attempts to match the previous command with a rule. If a match is found, a new command is created using the matched rule and executed.

Grab it on github. Install it right away. It went into my toolbelt in an instant.

Why the MS-DOS floppy disk cache was valid 2 seconds…

If you’re old enough to have used MS-DOS you know the benefits a read cache introduced back at the time for floppy disks. Without such a cache everything data intensive was magnitudes slower.

Now after all these years more and more stories emerge about how certain thresholds and timeings where set back in the days.

This is such a story:

Mark Zbikowski led the MS-DOS 2.0 project, and he sat down with a stopwatch while Aaron Reynolds and Chris Peters tried to swap floppy disks on an IBM PC as fast as they could.

They couldn’t do it under two seconds.

So the MS-DOS cache validity was set to two seconds. If two disk accesses occurred within two seconds of each other, the second one would assume that the cached values were still good.

GeekTyper was inspired by the various media where hacking is usually portrayed incorrectly.
Simply randomly mash your keyboard and code will be simulated on your screen.

This is hilarious! :-) I’ve had way to much fun poking keys while trying it out…

Of course there’s also a screensaver that you can install. Recommended for office use. Not recommended on airplanes and other public spaces.

2001-era docomo flip phone emoji font

NTT DoCoMo might not have been the first ones to release feature phones with actual emoji characters to be used in text messaging. But their set of original emojis is just oh-so-beautiful to look at.

With the help of Monica Dinculescu we now can enjoy these emojis on our modern era computing machines.


You can either get the font downloaded for free directly from Monicas page or you could use her SVG code to further make use of the great emojis.

the font download will get you this

If you go for the SVG link you will get some overview alike the one at the start of this post. If you wanted to further work with the raw vector data (SVG) in there you could use this simple trick:

Step 1: locate the emoji you want in the code of the page. Maybe by utilizing the developer tools of your browser.

Step 2: Copy that specific element that you want to your clipboard / into a new text document.

Step 3: add the proper header tag before the element you’ve copied.

<?xml version="1.0" encoding="utf-8"?>

Step 4: Save the contents now as a file with the .svg ending. You can now open it up in any SVG compatible editor, like Inkscape.

fear the flex of my tensor tympani muscle!

TIL that I could do something which I assumed everybody could do. I could make me hear a roaring thunder sound by flexing a muscle I did not know until now.

It’s quite interesting. The muscle is named “Tensor tympani” and it’s here:

Henry Vandyke Carter
 and one more author – Henry Gray (1918) Anatomy of the Human Body (See “Book” section below) Bartleby.comGray’s AnatomyPlate 907

The tensor tympani acts to dampen the noise produced by chewing. When tensed, the muscle pulls the malleus medially, tensing the tympanic membrane and damping vibration in the ear ossicles and thereby reducing the perceived amplitude of sounds.

So the eye has an Iris to control how much light makes it in. The ear has this muscle to dampen too loud sounds. And apparently not everyone is able to willingly control it. Bummer!

Contracting muscles produce vibration and sound. Slow twitch fibers produce 10 to 30 contractions per second (equivalent to 10 to 30 Hz sound frequency). Fast twitch fibers produce 30 to 70 contractions per second (equivalent to 30 to 70 Hz sound frequency). The vibration can be witnessed and felt by highly tensing one’s muscles, as when making a firm fist. The sound can be heard by pressing a highly tensed muscle against the ear, again a firm fist is a good example. The sound is usually described as a rumbling sound.

Some individuals can voluntarily produce this rumbling sound by contracting the tensor tympani muscle of the middle ear. The rumbling sound can also be heard when the neck or jaw muscles are highly tensed as when yawning deeply. This phenomenon has been known since (at least) 1884.

Interesting theories not started in my head. As I am very sensitive to chewing noises of all sorts – either produced by myself or by others. This could give an explanation to why.

Now excuse me, I need to flex this muscle and make the thunder roar!

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.

a wild Ma.K (Maschinen Krieger) appears

The franchise was started by Kow Yokoyama in the 1980’s. Yokoyama-san was a scratch-build modeller, artist and sculptor. Among his works he built machines of war that would fight in the 29th century, but took their visual cues from early 19th century weaponry and the early NASA space program. All his models were pieced together from numerous kits including armor, aircraft, cars and found objects (like ping pong balls).


Often described as WWII machinery in space, these kits are the perfect blend of sci-fi modelling with AFV weathering and finishing techniques…

I don’t like the long-tail Windows 10 default cursor

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.

left: like!
right: booh!

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.

what do you do with a rental car?

“The only thing we can say is that data show a number of people rent cars without driving them.”

Growing number of car-sharing users don’t rent cars for driving

Wait. What?

“Usually the only place I can take a nap while visiting my clients is a cybercafe in front of the station, but renting a car to sleep in is just a few hundred yen (several dollars), almost the same as staying in the cybercafe.”

N8.5 – Tokyu White

It always seems to me so much easier to meet a Hackers in Japan than anywhere else. Maybe social-gravity works different there. Or there are more of them.

Whatever the reason, I keep crossing paths with people that more or less deep-dive into topics and understand systems in ways and in details that you would normally not expect.

And todays example is a detail you would normally not think about:

The footbridge that was newly built in Shibuya was painted in N8.5. This is commonly known as “Tokyu White”…

“Tokyu White”, N8.5, … of course…if you would need a bucket of this you can order it online.

DLG Gütesiegel in japanese TV commercials

Catching up to some YouTube things during dinner made us see a Japanese TV commercial sporting the German DLG quality seal. Funny to see that these kind of quality seals carry over even to Japan…

The German Agricultural Society (Deutsche Landwirtschafts-Gesellschaft), commonly known as DLG, is an international non-profit organisation for agricultural industry in Germany. DLG was founded in 1885 by Max Eyth, has over 23,000 members as of 2011 and is headquartered in Frankfurt am Main. Its main purpose is to promote technical progress and scientific advances in the food and agricultural industry, including setting standards.


disk down, rinse and repeat.

After the sudden death of a hard drive in one of the house’ storage arrays (after 55997 hours of service) beginning of this month it has happened again:

With less than half the runtime of the previously dead disk this one is an early failure. Well within the warranty. Therefore the disk is already en route to be replaced by an RMA (Western Digital RMA process so far is spotless!)

Anyhow: This was a 4 TB drive. It’s in an array with 2-disk redundancy and 8 other drives. So the array still is operating with redundancy right now. Additionally a full backup exists as well as a hot-standby (but slower) offsite mirror.

I am quite confident to not loose data. But this raid-sync is going to take a bit longer. As drives get bigger, syncs get longer.

make linux fast (unsecure) again

The CPU/hardware related bugs surfacing the last couple of years have mostly been fixed by adjusting the software that is run. Sometimes only by disabling certain features of a CPU or patching the microcode in the CPU itself.

The issue with this is that by fixing these issues features got disabled and workarounds had been introduced that lowered performance. Dramatically so for some use-cases.

By how much? Well it really depends on your CPU and use-cases. But maybe you want to try yourself. If you want to know the most current parameters to pass to your kernel on boot-up to disable all the performance impacting fixes, go here:

It is not recommended to have this in productive use – as you can imagine. Those bugs where fixed for a reason.

80s code editor theme

The beginning of the decade saw the continuation of the clothing styles of the late 1970s and evolved into heavy metal fashion by the end. However, it had a lot of changes considering that, this fashion became more and more extravagant during the 80s.

The 80s included things like teased hair, ripped jeans, neon clothing and lots of colours and different designs which at first weren’t accepted for a lot of people.

Popular Culture in the 80s

Do you remember that endless summer back in ’84? Cruising down the ocean-highway with the top down, the wind in our hair and heads buzzing with neon dreams?
No, I don’t remember it either, but with this experimental theme we can go there.

Things you do with Microsoft Excel

Many of us are happy when they can accomplish the most simple tasks with Excel without pulling their own hair out.

And then there are these people who do something entirely different with Excel:

Finding engineering work quite unchallenging lately I decided to start this blog in which to share cool ways of solving engineering problems or just interesting modeling of natural phenomena in MS Excel 2003. I use mainly cell formulas with minimum of VBA in order to take advantage of the ease of “programming” and the native speed of the Excel spreadsheet.

file from the far future

I ran a VVV job to catalog a storage array I have. To my surprise at least one file had a very very strange timestamp:

Apparently the file in question was generated on an action cam which had lost its correct date and time setting at the time of recording…

The tool I am using to catalogue the storages is also worth a mention:

VVV is an application that catalogs the content of removable volumes like CD and DVD disks for off-line searching. Folders and files can also be arranged in a single, virtual file system. Each folder of this virtual file system can contain files from many disks so you can arrange your data in a simple and logical way.
VVV also stores metadata information from audio files: author, title, album and so on. Most audio formats are supported.

Kawasaki Frontale vs. Vissel Kobe

First: I am not at all interested or knowledgeable in football / soccer. But…

Several times a year I am for multiple weeks in the area of Musashikosugi ((武蔵小杉) which is part of the greater Tokyo area in Japan.

And because of these stays – I’ve probably been there for the accumulated time of 1 year – I’ve got attached to this area / community over time.

This includes all those things the community shares on various places on the internet so to a small degree I can stay informed.

For example: There is a fantastic blog (as for many other communities in Tokyo) that specifically shares community related information about Musashikosugi.

To understand the context you need to know that I’ve worked for Rakuten. The number one eCommerce company in Japan. This surely kick-started my interest in Japan overall.

I know from my time at Rakuten that the company engaged in a couple of sport sponsorships. One of them was the J1 League football clubVissel Kobe“.

Kawasaki, the area of which Musashikosugi is part of, also has such a football team called “Kawasaki Frontale“.

Through said blog it came to my attention that there was a game between those two football teams and…

Kawasaki won the game!

So despite me not being particularly interested in sports this news was quite exciting to see. It almost feels like some local patriotism feelings come up. And with the direct connection to my past employment it get’s even more exciting.

Go Kawasaki, go!
