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!
There’s the DJI drones that seemingly own the market at this point. Mostly used to take aerial images and movies. Your average YouTuber will probably have two or more of them.
Turns out that, if you add modern camera technology to these small flying objects and a lot of processing power you can do crazy things like indoor realtime 3D mapping…
Skydio is a vendor to look at when it somes to such interesting mapping applications.
The first sound card I got as an upgrade to a PC without sound back in 90s was the glorious Sound Blaster 16:
There were several different sound card options back in the days and all sounded a bit different.
A sound card (also known as an audio card) is an internal expansion card that provides input and output of audio signals to and from a computer under control of computer programs. The term sound card is also applied to external audio interfaces used for professional audio applications.Wikipedia
With the synthesizers and audio processing each series and make produced a distinctive sound. Some of us want to bring these sounds back. But keeping the (old) hardware running is an increasingly difficult task.
For example: The interface used by the above mentioned Sound Blaster 16 card is the ISA bus interface. This interface was introduced in 1981 and replaced in 1993. If you want to hear how such a sound card sounds today you would have to run hardware from this time period.
But some people are working towards getting at least some authentic sound back.
In this talk, Alan Hightower takes a look at the complexities, challenges, and even current progress at integrating all of the above cores into one FPGA based ISA sound card.
This is what the concept would bring if done:
Oh that would be soooooo nice to have all these vintage sound interfaces available and to be able to actually use them for audio output.

I played with SDR – Software Defined Radio – back in 2013. I’ve still got the equipment around.
Now that I am thinking about it – there is a practical use-case that I will look into in the coming months for sure for it. And just to mention this use case here: With SDR I could create a more versatile 443/886 Mhz receiver.
Anyhow. SDR hardware allows you to access a whole spectrum of radiosignals at once. And a common way to visualize the spectrum is to draw the amplitudes in a line add each new measurement as a new line – color/brightness coded.
What you get is some sort of waterfall diagram that looks like this:
Hertzian Landscapes (2019) is a live visualization of the radio spectrum. Unlike visible light, waves in the radio spectrum cannot be perceived by us directly yet this space is teeming with human activity. Hertzian Landscapes employs a digital receiver to scan large swaths of radio spectrum in near real-time and visualizes thousands of signals into a panoramic electromagnetic landscape. Users can zoom in to specific frequencies by positioning themselves in front of the panorama as if controlling a radio tuner with their body, giving them a sense of walking through the spectrum.http://www.hertzianlandscapes.com/
From radio broadcasts to weather satellites and from medical implants to aeronautical navigation, the radio spectrum is divided into hundreds of designated slices each tied to a specific application. Based on a localized frequency database that describes these slices, signals are annotated to provide information about their theoretical type and application.
SuperCollider is a platform for audio synthesis and algorithmic composition, used by musicians, artists, and researchers working with sound. It is free and open source software available for Windows, macOS, and Linux.
SuperCollider features three major components:
scsynth, a real-time audio server, forms the core of the platform. It features 400+ unit generators (“UGens”) for analysis, synthesis, and processing.
sclang, an interpreted programming language. It is focused on sound, but not limited to any specific domain. sclang controls scsynth via Open Sound Control.
scide is an editor for sclang with an integrated help system.
Usually when we visited lectures the notes and explanations where given on a chalk board or a projector. With the lecturer looking away from the audience most of the time.
This is where Light Boards come in handy. They allow the lecturer to face his audience and give explanations on a board…
I was made aways by Ryan Heffernans tweet on the project he did together with his son. He built one of these light boards! The short clip above shows his son on their board.
My son and I built a lightboard. You write on it like a whiteboard, but you can face your audience and the writing is illuminated. Commercial versions cost around $10k, but we made ours for $400 in parts from Home Depot. Here’s how.Ryan Heffernan Tweet
Of course there are commercial ready-made ones. But where’s the fun in that?
To remind you of the recently celebrated 42nd mission anniversary of the still active and data transmitting Voyager 2 space craft.
NASA’s Voyager 2 is the second spacecraft to enter interstellar space. On Dec. 10, 2018, the spacecraft joined its twin—Voyager 1—as the only human-made objects to enter the space between the starsVoyager 2 Homepage
And what reminded me of this astonishing achievement.
Think of this: You are flying at >34k miles per hour. You are >18.5 billion miles away from earth. (It’ll take >16 hours at light speed one-way trip from earth to you). And on top, you are still able to send data back to earth at 159 bytes per second.
Microsoft recently is releasing a lot of tools and assets for developers and terminal monkeys.
This is good. Very nice of them.
The recent release of a font specifically for terminal and code editing use seems worth a mention here:
Cascadia Code was announced this past May at Microsoft’s Build event. It is the latest monospaced font shipped from Microsoft and provides a fresh experience for command line experiences and code editors. Cascadia Code was developed hand-in-hand with the new Windows Terminal application. This font is most recommended to be used with terminal applications and text editors such as Visual Studio and Visual Studio Code.Cascadia Code announcement
What’s most interesting about this: It’s got code ligatures. Just recently a lot of development focussed fonts showed up and they started to incorporate special characters for development specific character combinations:
Cascadia Code supports programming ligatures! Programming ligatures are most useful when writing code, as they create new glyphs by combining characters. This helps make code more readable and user-friendly for some people.Cascadia
I’ve written on this topic before here. And as developers venture more into these generative algorithms it’s all that more fun to see even the intermediate results.
Oskar Stålberg writes about his little experiments and bigger libraries on Twitter. The above short demonstration was created by him.
Especially worth a look is the library he made available on GitHub: mxgmn/WaveFunctionCollapse.
Some more context, of questionable helpfulness:
In quantum mechanics, wave function collapse occurs when a wave function—initially in a superposition of several eigenstates—reduces to a single eigenstate due to interaction with the external world. This interaction is called an “observation”. It is the essence of a measurement in quantum mechanics which connects the wave function with classical observables like position and momentum. Collapse is one of two processes by which quantum systems evolve in time; the other is the continuous evolution via the Schrödinger equation. Collapse is a black box for a thermodynamically irreversible interaction with a classical environment. Calculations of quantum decoherence predict apparent wave function collapse when a superposition forms between the quantum system’s states and the environment’s states. Significantly, the combined wave function of the system and environment continue to obey the Schrödinger equation.Wikipedia: WFC
Right. Well. Told you. Here are some nice graphics of this applied to calm you:
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.

If you own a modern age phone it’s very likely that it will store the photos you take in a wonderful format called HEIC – or “High Efficiency Image File Format (HEIF)”.
So HEIC does not quite fit yet. But you can make it fit with this on Linux.
Imagemagick and current GIMP installations apparently still don’t come pre-compiled with HEIF support. But you can install a tool to easily convert an HEIC image into a JPG file on the command line.
apt install libheif-examples
and then the tool heif-convert is your friend.
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.
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.
Augmented Reality – AR – is getting some buzz here and there throughout the last 20 years almost. With hardware becoming more powerful and optics+light hardware becoming cheaper and more efficient it’s still all but close to become widely used and available.
Many refer to some one-trick pony feature in location-based games like “Pokemon Go” to being “AR”. But actual useful cases of AR are there but not feasible with current hardware generations.
Nevertheless a team in california has taken our the scissors and keyboards and made HoloKit:
HoloKit features super sharp optics quality and a 76-degree diagonal field of view. Pairing with a smartphone, HoloKit can perform an inside out tracking function, which uses the changing perspective on the outside world to note changes in its own position. HoloKit merges the real and the virtual in a smart way. While you see through the real world, virtual objects are blended into it. Powered by the accurate gyro and camera on smart phones, HoloKit solidly places virtual objects onto your table or floor, as if they were physically there without physical makers. These virtual objects will stay in the same place even if you walk away, just like real physical objects.https://holokit.io/
HoloKit is different from screen-based AR experience like Tango. You can directly see through the headset and view the real world as is, and in the meantime the virtual objects are projected on top of the real world, as opposed to viewing both the real and the virtual through a smartphone camera.
Browsers can do many things. It’s probably your main window into the vast internet. Lots of things need visualization. And if you want to know how it’s done, maybe do one yourself, then…
And to further learn what it’s all about, go to Amelia Wattenbergers blog and take a stroll:
So, you want to create amazing data visualizations on the web and you keep hearing about D3.js. But what is D3.js, and how can you learn it? Let’s start with the question: What is D3?An Introduction to D3.js
While it might seem like D3.js is an all-encompassing framework, it’s really just a collection of small modules. Here are all of the modules: each is visualized as a circle – larger circles are modules with larger file sizes.
The demon core was a spherical 6.2-kilogram (14 lb) subcritical mass of plutonium 89 millimetres (3.5 in) in diameter, that was involved in two criticality accidents, on August 21, 1945 and May 21, 1946.Wikipedia: Demon core

You might, or might not be aware of my passion for black clothing. I like the simplicity and absence of noise.
Anyway. You might not be aware of the wonderful world of black as-in paint.
Apparently the current record holder in blackness (measured in percent absorption of visible light) is a product called “Vanta Black”.
Vantablack is a material developed by Surrey NanoSystems in the United Kingdom and is one of the darkest substances known, absorbing up to 99.96% of visible light (at 663 nm if the light is perpendicular to the material).Wikipedia: Vantablack
The name is a compound of the acronym VANTA (vertically aligned carbon nanotube arrays) and the color black.
Unfortunately this blackest-of-black coating is not readily available for purchase. Export rules apply and so it’s usually not sold to civilians at all.
“What is the next best thing?”, you ask. Well it’s BLACK 2.0.
Deep convolutional networks have become a popular tool for image generation and restoration. Generally, their excellent performance is imputed to their ability to learn realistic image priors from a large number of example images. In this paper, we show that, on the contrary, the structure of a generator network is sufficient to capture a great deal of low-level image statistics prior to any learning. In order to do so, we show that a randomly-initialized neural network can be used as a handcrafted prior with excellent results in standard inverse problems such as denoising, super-resolution, and inpainting. Furthermore, the same prior can be used to invert deep neural representations to diagnose them, and to restore images based on flash-no flash input pairs.Deep Image Prior Paper
Apart from its diverse applications, our approach highlights the inductive bias captured by standard generator network architectures. It also bridges the gap between two very popular families of image restoration methods: learning-based methods using deep convolutional networks and learning-free methods based on handcrafted image priors such as self-similarity.
