CCCamp 2019 – 21. – 25. August 2019

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.

generate web-ready graphs and data visualizations without coding

Plot.ly is both a well known software library of impressive visualizations and a company providing software and know-how around visualizations.

With the libraries requiring a fair amount of know-how and programming to be useful to everyone there is now seemingly a multitude of tools that wraps the powers of the library and provides a great online-/web-browser experience to create impressive visualizations:

The access path to this quite powerful tool does somehow not be very easily found. So I am linking to it for your and my later reference.

retrofuturism sketches

On twitter and artstation I’ve came across Sheng Lam. An artist with a quite fascinating way of sketching. Take a look and be inspired:

a red triangle on the window

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.

some of the windows have red triangles pointing down
do you see the triangles pointing down on the upper right wall?

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.

making ICs at home

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.

Be inspired:

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!

Bitmap & tilemap generation with the help of ideas from quantum mechanics

You can get a grasp at the beautiful side of science with visualizations and algorithms that output visual results.

This is the example of producing lots and lots of complex data (houses!) from a small set of input data. It is widely used in game development but also can be helpful to generate parameterized test and simulation environments for machine learning.

So before sending you over to the more detailed explanation the visual example:

This is a lot of different house images. Those are generated using a program called WaveFunctionCollapse:

WFC initializes output bitmap in a completely unobserved state, where each pixel value is in superposition of colors of the input bitmap (so if the input was black & white then the unobserved states are shown in different shades of grey). The coefficients in these superpositions are real numbers, not complex numbers, so it doesn’t do the actual quantum mechanics, but it was inspired by QM. Then the program goes into the observation-propagation cycle:

On each observation step an NxN region is chosen among the unobserved which has the lowest Shannon entropy. This region’s state then collapses into a definite state according to its coefficients and the distribution of NxN patterns in the input.

On each propagation step new information gained from the collapse on the previous step propagates through the output.

On each step the overall entropy decreases and in the end we have a completely observed state, the wave function has collapsed.

It may happen that during propagation all the coefficients for a certain pixel become zero. That means that the algorithm has run into a contradiction and can not continue. The problem of determining whether a certain bitmap allows other nontrivial bitmaps satisfying condition (C1) is NP-hard, so it’s impossible to create a fast solution that always finishes. In practice, however, the algorithm runs into contradictions surprisingly rarely.

Wave Function Collapse algorithm has been implemented in C++PythonKotlinRustJuliaGoHaxeJavaScript and adapted to Unity. You can download official executables from itch.io or run it in the browser. WFC generates levels in Bad NorthCaves of Qudseveral smaller games and many prototypes. It led to new research.

online celebrities: Elon Musk

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.

This is the example of such a newly developing “tracking journalism” site around the dazzling public character that is Elon Musk. It is called “elonmusk.today“.

Editor’s note: others have done great work exposing Musk’s shameless charlatan carnival barking. If you enjoy this sort of thing, I highly recommend Niya White’s excellent article Musk Misses: The Stories You Don’t Hear About Tesla Anymore …

Tesla battery survey

If there is any discussion or argument about electric mobility these days the topic of range and battery-aging is coming up rather quick.

Every once in a while you also hear these awesome stories about electric cars achieving total-driven-distances outrageously huge compared to combustion engine cars…

But what is it then, how does a battery in an electric car age over time and mileage? Given that car manufacturers seem to settle on a ca. 150.000km total-driven-miles baseline for giving a battery-capacity percentage guarantee. Something like…

The future owners of ID. models won’t need to worry about the durability of their batteries either, as Volkswagen will guarantee that the batteries will retain at least 70 per cent of their usable capacity even after eight years or 160,000 kilometres.

Volkswagen Newsroom

or

Model S and Model X – 8 years (with the exception of the original 60 kWh battery manufactured before 2015, which is covered for a period of 8 years or 125,000 miles, whichever comes first).

Model 3 – 8 years or 100,000 miles, whichever comes first, with minimum 70% retention of Battery capacity over the warranty period.

Model 3 with Long-Range Battery – 8 years or 120,000 miles, whichever comes first, with minimum 70% retention of Battery capacity over the warranty period.

Tesla

So. Guarantees are one thing. Reality another. There’s an interesting user-driven survey set-up where Tesla owners can hand in their cars data thus participate in the survey.

And it yields results (getting updated as you read…):

In a nutshell: It seems there is a good chance that your Tesla car might have an above 90% original-specified-battery-capacity after the guaranteed 100.000 miles and even after 150.000 miles (241.000km)…

Good news that is! Given that the average household will do about or less than 20.000 km/year it would mean over 12 years of use and the car still would hold 90% of battery charge. The battery being the most expensive single component on an electric car this is extremely good news as it’s unlikely that the battery will be the reason for the car to be scraped after this mileage.

I/O Is Faster Than the CPU

I/O is getting faster in servers that have fast programmable NICs and non-volatile main memory operating close to the speed of DRAM, but single-threaded CPU speeds have stagnated. Applications cannot take advantage of modern hardware capabilities when using interfaces built around abstractions that assume I/O to be slow. We therefore propose a structure for an OS called parakernel, which eliminates most OS abstractions and provides interfaces for applications to leverage the full potential of the underlying hardware. The parakernel facilitates application-level parallelism by securely partitioning the resources and multiplexing only those resources that are not partitioned.

Tilt your head, be more aggressive

“We show that tilting one’s head downward systematically changes the way the face is perceived, such that a neutral face—a face with no muscle movement or facial expression—appears to be more dominant when the head is tilted down,” explain researchers Zachary Witkower and Jessica Tracy of the University of British Columbia.

They’ve got 8 example sound snippets and it’s up to you to identify the fake or the real file:

look at the earth

Watch sunlight and weather patterns move across Earth throughout the day, and bask in the glory of our blue marble in real time.

Every 20 minutes (or every hour, you pick), Downlink updates your desktop background with the newest images of Earth.

Choose from 8 different views of Earth, including stunning full disk images from 3 different geostationary satellites.

Downlink is a macOS application which downloads the most current image taken by earth orbitting satellites. So what you see is as accurately depicting reality as technically possible right now.

Interestingly all this data comes from public domain sources. And the makers of the app have documented their sources:

Thanks to NASA, NOAA, JMA, Lockheed Martin, Harris Corporation, ULA, MHI, and everyone else who designed, built, launched, and operate GOES-16, GOES-17, and Himawari-8.
If you’d like to use the sources Downlink is built on top of, here is the file pointing to those resources. Use it, and tell me what you’ve built!

I am using macOS as well as Linux as my main desktop operating systems. My macs are set with Downlink. But what about my Linux machines?

Easy! The file referring to the sources looks like this:

With some simple steps on Linux we can grab the URL we want, download the image and update the desktop background.

Step 1: Getting the URL from this JSON.

Install jq, curl and xargs and in your shell run this:

curl -s http://downlinkapp.com/sources.json | jq -r '.sources[2].url.full' 

This will give you the URL “full” of the 2nd source in the list (Hiwamari-8).

Step 2: Download the image.

curl -s http://downlinkapp.com/sources.json | jq -r '.sources[2].url.full' | xargs -I{} curl -s -o background.jpg {}

By simply adding the xargs and curl call it will take the URL output from the command in front as input to the second curl call and download it. It also will store the file as “background.jpg”.

Step 3: Setting as background image.

Setting the background image of your desktop depends on what desktop software you are using on Linux. Depending on that you will need to look up in the manual how to set the background image from the command line.

But for most use cases there’s a tool that helps. It’s called Variety.

Variety is an open-source wallpaper changer for Linux
Variety is packed with great features, yet slim and easy to use. It can use local images or automatically download wallpapers from Unsplash and other online sources, allows you to rotate them on a regular interval, and provides easy ways to separate the great images from the junk. Variety can also display wise and funny quotations or a nice digital clock on the desktop.

Earth, Moon, Spaceship.

As you might know humans are going to go “back to the moon“. At least when you ask a certain eCommerce mogul.

We have been there already. 40+ years ago. And since then we have unlearnt how to do it.

Just to give an impression of what we as humans where capable to achieve 40 years ago:

Moon (below), Apollo 16 Command Module (left), Earth (right)

There’s a whole collection of these photos freely available for further digging. Go there and spend a day!

Imagine: Humans flew there and back. With 60s tech. What can we do now when we want it?

Of course. The important bit is not really flying there and back. The most important thing for me is perspective.

Look at that small blue-white marble. We should reset our perspectives regularly.

let AI convert videos to comic strips for you

Artificial Intelligence is used more and more to achieve tasks only humans could do before. Especially in the areas that need a certain technique to be mastered AI goes above and beyond what humans would be able to do.

In this case a team has implemented something that takes video inputs and generates a comic strip from this input. Imagine it to look like this:

Output

In this paper, we propose a solution to transform a video into a comics. We approach this task using a
neural style algorithm based on Generative Adversarial Networks (GANs).

Video Game History

Have you ever asked yourself what those generations coming after us will know about what was part of our culture when we grew up? As much as computers are a part of my story a bit of gaming also is.

From games on tape to games on floppy disks to CDs to no-media game streaming it has been quite a couple of decades. And with the demise of physical media access to the actual games will become harder for those games never delivered outside of online platforms. Those platforms will die. None of them will remain forever.

Hardware platforms follow the same logic: Today it’s the new hype. Tomorrow the software from yesterday won’t be supported by hardware and/or operating systems. Everything is in constant flux.

Emulation is a great tool for many use-cases. But it probably won’t solve all challenges. Preserving access to software and the knowledge around the required dependencies is the mission of the Video Game History Foundation.

Video game preservation matters because video games matter. Games are deeply ingrained in our culture, and they’re here to stay. They generated an unprecedented $91 billion dollars in revenue in 2016. They’re being collected by the Smithsonian, the Museum of Modern Art, and the Library of Congress. They’ve inspired dozens of feature films and even more books. They’re used as a medium of personal expression, as the means for raising money for charity, as educational tools, and in therapy.
And yet, despite all this, video game history is disappearing. The majority of games that have been created throughout history are no longer easily accessible to study and play. And even when we can play games, that playable code is only a part of the story.

Digital Daily Routine as an Experiment – “Digitaler Alltag als Experiment”

Last week we were approached by Prof. Dr. Nicole Zillien from Justus-Liebig-University in Gießen/Germany. She explained to us that she currently is working on a book.

In this book an empirical analysis is carried out on “quantified-self” approaches to real life problems.

With the lot of information and data we had posted on our personal website(s) like this blog and the “loosing weight” webpage apparently we qualified for being mentioned. We were asked if it would be okay to be named in the book or if we wanted to be pseudonymized.

Since everything we have posted online and which is publicly accessible right now can and should be quoted we were happy to give a go-ahead. We’re publishing things because we want it to spur further thoughts.

It will be out at the end of 2019 / beginning of 2020. As soon as it is out we hope to have a review copy to talk about it in this blog once again.

We do not know what exactly is being written and linked to us – we might as well end up as the worst example of all time. But well, then there’s something to learn in that as well.

Digital assistant language teacher

Since a couple of months we are trying harder to learn a foreign language.

And as we excepted it is very hard to get a proper grasp on speaking the language. Especially since it is a very different language to our mother tongue.

And while comfortably interacting with digital assistants around the house every day in english and german the thought came up: why don’t these digital assistants help with foreign language listening and speaking training?

I mean Google Assistant answers questions in the language you have asked them. Siri and Alexa need to know upfront in which language you are going to ask questions. But at least Alexa can translate between languages…

But with all seriousness: Why do we not already have the obvious killer feature delivered? Everyone could already have a personal language training partner…

a virtual network inside your machine

Did you ever start a horde of virtual machines and a complicated vm-only network set-up just to simulate a medium complex network and the interaction of nodes in that network? Well that’s a tiresome, error-prone and labour intensive process. Fear no more, there’s a tool to the rescue.

“Mininet creates a realistic virtual network, running real kernel, switch and application code, on a single machine (VM, cloud or native), in seconds, with a single command:”

frontpage_diagram

“Because you can easily interact with your network using the Mininet CLI (and API), customize it, share it with others, or deploy it on real hardware, Mininet is useful for development, teaching, and research. Mininet is also a great way to develop, share, and experiment with OpenFlow and Software-Defined Networking systems.

Mininet is actively developed and supported, and is released under a permissive BSD Open Source license. We encourage contribution of code, bug reports/fixes, documentation, and anything else that can improve the system!”

Security Engineering — The Book

The second edition of the book “Security Engineering” by Ross Anderson is available as a full download. It’s quite a reference and a must-read for anybody with an interest in security (which for example all developers should have).

“When I wrote the first edition, we put the chapters online free after four years and found that this boosted sales of the paper edition. People would find a useful chapter online and then buy the book to have it as a reference. Wiley and I agreed to do the same with the second edition, and now, four years after publication, I am putting all the chapters online for free. Enjoy them – and I hope you’ll buy the paper version to have as a conveient shelf reference.”

know your numbers!

Wikipedia describes latency this way:

“Latency is a measure of time delay experienced in a system, the precise definition of which depends on the system and the time being measured. In communications, the lower limit of latency is determined by the medium being used for communications. In reliable two-way communication systems, latency limits the maximum rate that information can be transmitted, as there is often a limit on the amount of information that is “in-flight” at any one moment. In the field of human-machine interaction, perceptible latency has a strong effect on user satisfaction and usability.” (Wikipedia)

Given that it’s quite important for any developer to know his numbers. Since latency has a huge impact on how software should be architected it’s important to keep that in mind:

Build a Brain – SPAUN

SPAUN or Semantic Pointer Architecture Unified Network is a promising next step in the pursuit to simulate a human brain. Built upon the Nengo Neural Simulator scientists at the University in Waterloo/Ontario were able to report on their first break-through results.

In 2013 there will be a book from Oxford University press called ‘How to build a brain’ which will describe in depth what made the astonishing results possible.

But what are the results?

Well that looks like number recognition. In fact that’s what it is. SPAUN – that’s how the scientists refer to their frankenstein-brain – is capable of solving 8 different tasks now. One of them is number recognition. There are videos of all 8 tasks being performed.

The Semantic Pointers are named after the pointers usually common in computer science:

“Higher-level cognitive functions in biological systems are made possible by semantic pointers. Semantic pointers are neural representations that carry partial semantic content and are composable into the representational structures necessary to support complex cognition.

The term ‘semantic pointer’ was chosen because the representations in the architecture are like ‘pointers’ in computer science (insofar as they can be ‘dereferenced’ to access large amounts of information which they do not directly carry). However, they are ‘semantic’ (unlike pointers in computer science) because these representations capture relations in a semantic vector space in virtue of their distances to one another, as typically envisaged by connectionists. “

practical filesystem design

In November 1998 there was a book released about file system design taking the Be File System as the central example.

“This is the new guide to the design and implementation of file systems in general, and the Be File System (BFS) in particular. This book covers all topics related to file systems, going into considerable depth where traditional operating systems books often stop. Advanced topics are covered in detail such as journaling, attributes, indexing and query processing. Built from scratch as a modern 64 bit, journaled file system, BFS is the primary file system for the Be Operating System (BeOS), which was designed for high performance multimedia applications.

You do not have to be a kernel architect or file system engineer to use Practical File System Design. Neither do you have to be a BeOS developer or user. Only basic knowledge of C is required. If you have ever wondered about how file systems work, how to implement one, or want to learn more about the Be File System, this book is all you will need.”

If you’re interested in the matter I definitely recommend reading it – it’s available for free in PDF format and will help to understand what those file system patterns are all about – even in terms of things we still haven’t gotten from our ‘modern filesystems’ today.

This October I had the pleasure to fly to Tokyo for the second time in 2012.

The development unit of Rakuten Japan was hosting the 7th Rakuten Technology Conference in Rakuten Tower 1 in Tokyo.

The schedule was packed with up to 6 tracks in parallel. From research to grass-roots-development a lot of interesting topics.

open source audio codecs getting better

Some weeks ago I heard about a new audio codec which is being developed as open source – very similar to vorbis – the previous open source approach to audio codecs.

This time it seems that they’ve got some standardization into the play so it might be more successful than vorbis was.

“Opus is a totally open, royalty-free, highly versatile audio codec. Opus is unmatched for interactive speech and music transmission over the Internet, but also intended for storage and streaming applications. It is standardized by the Internet Engineering Task Force (IETF) as RFC 6716 which incorporated technology from Skype’s SILK codec and Xiph.Org’s CELT codec.”

Photosynth now mobile…

It’s been some months years since the once Microsoft Research Project got public and Microsoft started offering it’s great Photosynth service to the public.

I’ve been using the Microsoft panoramic and Photosynth tools for years now and I tend to say that they are the best tools one can get to create fast, easy and high-quality panoramic images.

There is photosynth.net to store all those panoramic pictures like this one from 2008:

The photosynth technology itself contains several other interesting technologies like SeaDragon which allows high quality image zooming on current internet connection speeds.

This awesome technology is as of now available on the iPhone (3GS and upwards) and it’s better than all the other panoramic tools I’ve used on a phone.

benchmarking the sones GraphDB (on Mono (sgen) and .NET)

Since we’re at it – we not only took the new Mono garbage collector through it’s paces regarding linear scaling but we also made some interesting measurements when it comes to query performance on the two .NET platform alternatives.

The same data was used as in the last article about the Mono GC. It’s basically a set of 200.000 nodes which hold between 15 to 25 edges to instances of another type of nodes. One INSERT operation means that the starting node and all edges + connected nodes are inserted at once.

We did not use any bulk loading optimizations – we just fed the sones GraphDB with the INSERT queries. We tested on two platforms – on Windows x64 we used the Microsoft .NET Framework and on Linux x64 we used a current Mono 2.7 build which soon will be replaced by the 2.8 release.

After the import was done we started the benchmarking runs. Every run was given a specified time to complete it’s job. The number of queries that were executed within this time window was logged. Each run utilized 10 simultaneously querying clients. Each client executed randomly generated queries with pre-specified complexity.

The Import

Not surprisingly both platforms are almost head-to-head in average import times. While Mono starts way faster than .NET the .NET platform is faster at the end with a larger dataset. We also measured the ram consumption on each platform and it turns out that while Mono takes 17 kbyte per complex insert operation on average the Microsoft .NET Framework only seems to take 11 kbyte per complex insert operation.

The Benchmark

Let the charts speak for themselves first:

mononet

click to enlarge

benchmark-mono-sgen
click on the picture to enlarge

benchmark-dotnet
click on the picture to enlarge

As you can see on both platforms the sones GraphDB is able to work through more than 2.000 queries per second on average. For the longest running benchmark (1800 seconds) with all the data imported .NET allows us to answer 2.339 queries per second while Mono allows us to answer 1.980 queries per second.

The Conclusion

With the new generational garbage collector Mono surely made a great leap forward. It’s impressive to see the progress the Mono team was able to make in the last months regarding performance and memory consumption. We’re already considering Mono an important part of our platform strategy – this new garbage collector and benchmark results are showing us that it’s the right thing to do!

UPDATE: There was a mishap in the “import objects per second” row of the above table.

sones GraphDB Visualization Tool

We want to show you something today: Not everybody has an idea what to think and do with a graph data structure. Not even talking about a whole graph database management system. In fact what everybody needs is something to get “in touch” with those kinds of data representations.

To make the graphs you are creating with the sones GraphDB that much more touchable we give you a sneak peak at our newest addition of the sone GraphDB toolset: the VisualGraph tool.

This tool connects to a running database and allows you to run queries on that database. The result of those queries is then presented to you in a much more natural and intuitive way, compared to the usual JSON and XML outputs. Even more: you can play with your queries and your data and see and feel what it’s like to work with a graph.

Expect this tool to be released in the next 1-2 months as open source. Everyone can use it, Everyone can benefit from it.

Oh. Almost forgot the video:

 

(Watch it in full screen if you can)

So what exactly is Microsoft Research doing?

I am proud to anounce that there’s a video publicly available which shows parts and projects Microsoft Research is working on currently. It’s great to see theses projects, concepts and ideas become publicly available one by one:

“Craig Mundie, chief research and strategy officer of Microsoft, presents “Rethinking Computing,” a look a how software and information technology can help solve the most pressing global challenges we face today. Part of UW’s Computer Science and Engineering’s Distinguished Lecture Series, Mundie demonstrates a number of current and future-looking technologies that show how computer science is changing scientific exploration and discovery in exciting ways. He discusses the role of new science in solving the global energy crisis, and answer questions from the audience.”

want some more expresso?

Almost three years ago I wrote about this nice little Regular Expression Tool which provides not only a RegEx-Builder but also a clean and nice interface to test and play.

It was a CodeProject sample project in that time and as it turns out it became a full blown version 3!

Obviously the user interface was revamped completely:

expresso3 So you now not only get the Testing and playing but also a Regular Expression Library, a cool How-To, a more useable design mode and you can even output your final regular expressions to C#, VB.NET or managed C++!

Great stuff! Even better is the fact that it does not come at any costs. Despite the fact that there’s a registration you can just get your free license on their website.
