When you are dealing with IoT protocols, especially at hobby-level, you probably came across the MQTT protocol and the challenge to have all those different devices that are supposed to be connected actually get connected – preferably using the MQTT protocol.
Recently this little project came to my attention:
OpenMQTTGateway project goal is to concentrate in one gateway different technologies, decreasing by the way the number of proprietary gateways needed, and hiding the different technologies singularity behind a simple & wide spread communication protocol: MQTT.OpenMQTTGateway
OpenMQTTGateway support very mature technologies like basic 433mhz/315mhz protocols & infrared (IR) so as to make your old dumb devices “smart” and avoid you to throw then away. These devices have also the advantages of having a lower cost compared to Zwave or more sophisticated protocols. OMG support also up to date technologies like Bluetooth Low Energy (BLE) or LORA.
Of course, there is a compatible device list…
Every once in a while I need to take an image or duplicate an SSD/SDCard/Harddisk. And it’s gotten quite complicated to get the proper formatting and alignment when you want to achieve certain things.
For example creating a EFI compatible bootable USB stick is not as straight forward as one would think.
In those cases, a tool called rufus helps:
For all other cases I am using the HDDGuru tool on Windows.
HDD Raw Copy Tool is a utility for low-level, sector-by-sector hard disk duplication and image creation.
- Supported interfaces: S-ATA (SATA), IDE (E-IDE), SCSI, SAS, USB, FIREWIRE.
- Big drives (LBA-48) are supported.
- Supported HDD/SSD Manufacturers: Intel, OCZ, Samsung, Kingston, Maxtor, Hitachi, Seagate, Samsung, Toshiba, Fujitsu, IBM, Quantum, Western Digital, and almost any other not listed here.
- The program also supports low-level duplication of FLASH cards (SD/MMC, MemoryStick, CompactFlash, SmartMedia, XD) using a card-reader.
HDD Raw Copy tool makes an exact duplicate of a SATA, IDE, SAS, SCSI or SSD hard disk drive. Will also work with any USB and FIREWIRE external drive enclosures as well as SD, MMC, MemoryStick and CompactFlash media.
When you need something to listen to it could be Podcasts that you are missing in your life.
A good place to start with those is a directory of podcasts, that even helps with categories and search functionality. Just like fyyd:
Of course as you can find all sorts of podcast there you can also find ours.
brace for marketing:
Friend OS, a modular, fully-customizable operating system accessible via any device that can support a modern web browser, or Friend’s Android and iOS apps. Friend OS leverages Internet and blockchain technologies to offer all the features of a commercial operating system, but one that gives you access to a secure and private cloud-based virtual desktop anytime, anywhere, no matter what hardware or software you use.
So what does this all mean? It’s apparently a web application scaled up to behave and be used like an operating system. It encapsulates an application and directory/filesystem like concept and essentially lives in one of your browser windows.
As long as you’ve got a supported browser, all your apps and data will be accessible through this. They claim.
It’s interesting as there is a lot of open source in there and even some docker effort made to get it running. Seems abandoned / not updated at the time of writing, but it’s a nice concept to begin with anyways.

It started with this tweet about someone called Ayliean apparently drawing a plant based upon set rules and rolling a dice.
And because generative art in itself is fascinating I am frequently pulled into such things. Like this dungeon generator or these city maps or generated audio or face generators or buildings and patterns…
On the topic of flowers there’s another actual implementation of the above mentioned concept available:
Jiří Praus@jipraus has made a nice LED sphere.
I was pointing to BitSavers before. And I will do it again as it’s a never ending source of joy.
Now some old schematics had been spilled into my feeds that show how logic gates had been implemented with transformers only.
And not only BitSaver is on this path of sharing knowledge, also TubeTime is such a nice account to follow and read.
Previously you had to be in Japan or to have a japanese AppStore account to get access to software that allows you to manage and add SUICA cards to your wallet and use it right-away for public transport.
Now with the 2020 olympics approaching more and more tourist support-apps are made available to non-japanese audiences.
Just like this little helper:
So the scenario was: You arrive at an airport in Japan. And the first thing you needed to do to use the public transport system was to get such a SUICA card either purchased or topped-up.
This is a straight forward process and they even came up with “Tourist SUICA” cards that will deactivate themselves after a certain amount of time and are cheaper to purchase upfront – still it was a process you had to know how it works.
With the above helper app you’re simply doing this:
- Download app.
- Make sure you’ve got Apple Pay set-up with at least one of your credit cards
- Use the SuicaEng app to create a brand new SUICA card out of thin air and top it up right there.
- (optional) push your SUICA card to your watch to simplify the purchase processes even more – you’ll just tap your wrist to pass through gates or purchase goods.
When you own a recent iOS device (iOS 11 and up) you’ve got the choice between “High Efficiency” or “Most Compatible” as the format all pictures are being stored by the camera app.
Most Compatible being the JPEG format that is widely used around the internet and other cameras out there and the “High Efficiency” coming from the introduction of a new file format and compression/reduction algorithms.
A pointer to more information about the format:
High Efficiency Image File Format (HEIF), also known as High Efficiency Image Coding (HEIC), is a file format for individual images and image sequences. It was developed by the Moving Picture Experts Group (MPEG) and is defined by MPEG-H Part 12 (ISO/IEC 23008-12). The MPEG group claims that twice as much information can be stored in a HEIF image as in a JPEG image of the same size, resulting in a better quality image. HEIF also supports animation, and is capable of storing more information than an animated GIF at a small fraction of the size.Wikipedia: HEIF
As Apple is aware this new format is not compatible with any existing tool chain to work with pictures from cameras. So you would either need new, upgraded tools (the Apple-way) or you would need to convert your images to the “older” – not-so-efficient JPEG format.
To my surprise it’s not trivial to find a conversion tool. For Linux I’ve already wrote about such a tool here.
For macOS and Windows, look no further. Waltr2 is an app catering your conversion needs with a drag-and-drop interface.
It’s advertised as being free and offline. And it works a treat for me.
Almost exactly 1 year ago I wrote about transit maps. And it seems to be a recurring topic. And rightfully so – it’s an interesting topic.
Along the presentation of a redesigned Singapore transit map, there’s more content to gather on the “Transit Mapping Symposium” website.
The “Transit Mapping Symposium” will take place in Seoul / South-Korea on 20/21st of April 2020 with researchers and designers meeting up.
The Transit Mapping Symposium is a yearly international gathering of transport networks professionals, a unique opportunity to share achievements, challenges and vision.
Our participants and speakers include experts from all fields of the industry:
– Network Operators
– Transport Authorities
– Digital Platforms
As I am a bit late to the party on this: There’s, just like last year, a nice generative art tool provided by bleeptrack to generate your very own 36c3 themed headlines/logos:

So with the new year started it might be worth looking into some patterns different from the ones we are usually dealing with. So how about a bit of 3D graphics, shaders and modelling?!
Get your gear:
Blender is the free and open source 3D creation suite. It supports the entirety of the 3D pipeline—modeling, rigging, animation, simulation, rendering, compositing and motion tracking, video editing and 2D animation pipeline.https://www.blender.org/
And then get a starting point. Be quick, as this is on Twitter it might fade away:
There’s so much interesting stuff in there – and lots to learn!
DSEG is a free font family, which imitate seven and fourteen segment display(7SEG,14SEG). DSEG have special features:
- DSEG includes the roman-alphabet and symbol glyphs.
- More than 50 types are available.
- True type font(*.ttf) and Web Open Type File Format (*.woff, *.woff2) are in a package.
- DSEG is licensed under the SIL Open Font License 1.1.

Sometimes you come across things in documentations. You read them. And then you read them again.
And then you write a post about it. May I present HTMLMediaElement.canPlayType():
It almost feels like we’ve made a step forward into a more probabilistic approach of computing…
And if you want it too, there is the how-to available on the RaspberryPi forum.
Some things you find on GitHub are more interesting and frightening than others.
This one is both and some more. What is it you ask?
R2 Bitcoin Arbitrager is an automatic arbitrage trading application targeting Bitcoin exchanges.
So it’s buying and selling Bitcoins. And it’s doing this on different markets.
On the topic of arbitrage Wikipedia has something to say:
In economics and finance, arbitrage is the practice of taking advantage of a price difference between two or more markets: striking a combination of matching deals that capitalize upon the imbalance, the profit being the difference between the market prices at which the unit is traded.https://en.wikipedia.org/wiki/Arbitrage
For example, an arbitrage opportunity is present when there is the opportunity to instantaneously buy something for a low price and sell it for a higher price.
Now this already is the second version of the tool and already 2 years old. See it as some sort of interesting archeological specimem. Please refrain to actually so something harmful with it.
I am writing this down here because apart from it’s obvious horrors this is a good starting point to understand how these computer-trading-systems do work in principle.
Given that an architectural drawing is also included it gives all sorts of starting points to thoughts.
Also. What could possibly go wrong if a tool to buy/sell on actual markets with actual bitcoins is confident enough to include the “maxTargetProfit” configuration option. Effectively setting the top-line of profit you’re going to make!!!111

It’s 3.8 kg and delivers 25.5 kg of force. Impressive! And it’s in stores (in Japan).
The “Every Muscle Suit” has a lot going for it. Weighing just 3.8 kilograms, the pneumatic artificial muscle suit is powerful enough to generate up to 25.5 kilogram-force and effectively relieves pressure on users’ backs when performing activities like heavy lifting.
Best of all, its streamlined design conceals an advanced air pressure system that doesn’t require electricity or batteries.Japan Today
