In the last post, I explored the graveyard of ‘bricked’ devices—hardware rendered useless by corporate decisions. It’s a stark reminder that when you don’t control the software, you don’t truly own the hardware. The clear alternative is Open Source, but that path has its own critical vulnerability: sustainability.

But this is where the journey gets complicated. We flee to platforms like Home Assistant and embrace open-hardware projects, expecting a haven of stability and privacy. And while we find it, we often forget a crucial truth: “free and open source” does not mean free to create.

The promise of the “smart home” was a future of convenience, efficiency, and seamless automation. We bought into the vision of light bulbs that dim with a voice command, thermostats that learn our habits, and security systems we can monitor from halfway across the world. But for a growing number of consumers, that dream is turning into a nightmare of expensive, useless hardware. The culprit? A business model built on centralised control and proprietary systems.

As a new year begins, it’s a natural time for reflection. Looking back at the history of this blog, it started during my years working in online education. I was fortunate to be surrounded by inspiring colleagues who lived by the principles of “working out loud” and developing ideas “out in the open”. It was a vibrant, collaborative time.

A lot of water has flowed down the rivers Murray and Drau since then, and I’ll be the first to admit that my practice of sharing my work has become sporadic at best. I’m extremely keen to change that.

I’ve been living and working in Australia for a good while now, having moved from Europe with a healthy dose of open-source enthusiasm. Over the years, however, I can’t help but notice a stark difference between the two continents: the politically engaged, almost rebellious, hacker culture that is so vibrant in Europe seems to be missing its pulse here Down Under.

This has really hit home for me while watching the live streams from the 39th annual Chaos Computer Club Congress (39C3) in Hamburg. It’s one of Europe’s largest gatherings of hackers, activists, and creatives who don’t just write code, but actively question and shape the world it runs on. It’s a cultural phenomenon, not just a tech conference.

Having just wasted a few hours on getting this Java software running on Linux I am documenting this for future reference and hopefully saving other LoRa / TTN folks some time.

Prerequisites

Install a Java JDK + JavaFX. This should work with the default OpenJDK 8 or 9 which comes as part of the Ubuntu repositories. I ended up installing Oracle JDK 8 as well as I thought the error might be related to OpenJDK.

Unfortunately it is still much harder than necessary to find notebook hardware to use with Ubuntu (or other Linux variants). This blog is full of past experiences (some of them quite time-consuming) on finding notebook hardware that will work without too much fiddling. This short note is to document my recent research on that front to help others who want to do the same (as there doesn’t seem to be a lot of good current info around).

Add SDK repository

sudo add-apt-repository ppa:ubuntu-sdk-team/ppa

sudo apt-get update sudo apt-get install ubuntu-device-flash`

Enable USB Debugging on the device

1. Make sure you have developer mode enabled (see http://developer.android.com/tools/device.html if you are unsure).
2. Navigate to Settings > Developer options
3. Enable USB Debugging. When a device is connected, you will be prompted in Android to authorize it.

Unlock Bootloader

adb reboot bootloader

fastboot oem unlock fastboot reboot`

There are plenty of sites out there that give advise on this topic, unfortunately most of them are highly ad-infested to the point of being unreadable as well as only containing single bit rather that an overall picture. This is a collection of useful links to source materials as well as steps necessary to install.

Foursquare decided that it was too hard for them to compete with location services like Yelp and split their app into two separate apps. Whilst that might make sense to the 4Square CEO and his VC masters, it makes no sense from a users perspective. Foursquare can be a bit of a battery hog already, and having 2 apps to open and “annoy” you with notifications is not an improvement by any means. And if I wanted Foursquare to be Yelp – I would have used Yelp in the first place. So no – I do not want to install another separate check-in App (called Swarm). One battery hogging location app was enough.

I just had one of my old hand-me-down phones returned by my offspring in a great condition (junior is very careful with his equipment – well done young man !). This doesn’t happen all too often shows that the Nexus S is a decently built phone. This is also a good example of breaking the built-in obsolescence of modern phones. This particular unit has served me well for nearly 2 years (my average is one year) and served 2 kids after that.

Install scanbuttond

Download the “Debian Experimental” package from http://pkgs.org/download/scanbuttond

sudo dpkg -i scanbuttond_0.2.3.cvs20090713-14_i386.deb

This step is only for the Fujitsu ScanSnap support. For other scanners you can probably install from the Ubuntu Repository

Scanner config

vim 40-libsane.rules
#add this line
ATTRS{idVendor}=="04c5", ATTRS{idProduct}=="11a2", ENV{libsane_matched}="yes"

Permissions

sudo adduser saned scanner

Useful command lines for troubleshooting

Since I had a few trouble getting this scanner to work properly I found the following commands highly useful in locating the issue.

Since I am tired to constantly recite this list whenever one of these designer-type people tells me that they need Adobe’s Whatever Suite to do some basic task here is a summary that I can point them to.
