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).
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.
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.
I have recently been looking at different CAD options on Ubuntu and LibreCAD (http://librecad.org/) is looking like the best option for my needs at current (apart from the wish there would be some DWG support).
Since the main Ubuntu repositories are usually a fair bit behind the lastest stable realeases of LibreCAD you need to add the LibreCAD Dev PPA Repository
Whilst I am by no means a photographer I do end up taking quite a few photos (these days pretty much exclusively on my phone) and the management of these photos can be a pain. So far I have never found an program worth the pain over plain old file management.
But having stumbled across Darktable (http://darktable.org/) I think I might have found a worthwile package.
This is an interesting report and info-graphic by the folks at VisionMobile on a new way of measuring the openness of some mobile open source projects.
The Open Governance Index measures the true openness of eight open source projects – Android, Qt, Symbian, MeeGo, Mozilla, WebKit, Linux and Eclipse – and analyses how governance, and not licenses, tell the full story of a project’s openness, across transparency, influence and control.
Finally I made the effort to completely get rid of my Facebook Account. After initially getting a Facebook Account in the very early days (as an ‘occupational hazard’ to investigate the potential of Facebook Applications) I have always been suspicious of the companies motives and decided not to use such a closed system as a base for application development.
Recent developments have only confirmed this suspision:
Instead I will concentrate all of my content inside this blog (including as a backup for other social services I create). I believe the control over my own content is important enough for me to warrant the extra effort.
After recently researching the available software for e-book creation for some of our clients (in the education sector) I came across quite a number of options. However after some further look into the option and trying some I was able narrowed the field down to 2 options that seem to be reasonably user-friendly and matured. The two are using a very different approach and will suit different types of users. One is a native e-book writer which will give better low-level control for the more technical types. The other is a plugin to the popular OpenOffice (or LibreOffice) Office Suites.
The release of the latest Ubuntu Version has been seen by a number of commentators as the most end-user friendly yet and signals another milestone in the readiness of Free and Open Source Software (FOSS) for more widespread (and business) use.
As a long-term user of a number of different Operating Systems and as SME Owner for the last 15 years I have overseen the gradual replacement of a number of proprietary software solutions with FOSS Alternatives. With the beginning of the new financial year however, we are planning to go another step further and are starting to change our default Operating System to Ubuntu (from MS Windows).
This is an interesting info-graphic comparing the 3 most popular OpenSource Content Management Systems.
While I don’t really agree with some of the metrics (such as the web-service stats) it is never the less a very good visual overview. As a long-term user of WordPress and Drupal there are some good points to give a quick overview.
Recently my father, who has so far not wanted to have anything to do with computers, decided to change all of this with age 67. While initially surprised (and remembering the comments I got when sitting in front of computers as a teenager instead of working on the family farm), I quite liked the idea. It’s a great to see him still wanting to explore and learn new things.
Unfortunately since there is approximately 17.000km between us, there was a limited amount I could do to help him get set up. So my eldest sister (as she always has to do) ended up having to help out instead. Finding hardware was the easy part and very cheap these days (and since it was bought online I could help with the technical aspects). However the machines in that particular shop came as white-boxes without an Operating System (which is a good thing in my book).
