Ubuntu Touch may step in where Firefox OS finished….maybe?
We certainly have a strong case for an alternative to Android because we should get a choice to be free of Google’s massive data collection infrastructure that is tracking everything we do and everywhere we go with our phones. Revelations for example that Android 8 screen scrapes every app in the system are mind boggling.…

Computing resources optimisation [2D]
I am going ahead with this so I have been busy over the last few days installing and removing things around the place. To date I have installed the old mediapc chassis with a new board, CPU and RAM, GA-B250M-D3H with Kaby Lake Pentium G4560, and moving all three disks across from serverpc. It was…

Linux video driver issues
One of the challenges with Linux is that bug fixes can be slow to be developed and there can be issues when libraries are updated in a component of a distro in a different time cycle from other parts and therefore break software. For example, in Qgis there is a version of it that depends…

Computing Resources Optimisation [2C]
Still looking at this, really just fine tuning expectations / specs. Last time I talked about task separation. Running stuff on mediapc is still a test case really. What has turned out to be important however is limitations on mediapc caused by it having an old CPU that is slow to decode some video formats.…

Scanning with Linux
As we all know, I have gradually moved lots of things I do from Windows to Linux over time, but still have a computer running the Home edition of Windows 10. One of the few things that still runs on Windows 10 is my Epson Perfection V200 Photo scanner. Well it did work well on…

Computing resources optimisation [2B]
Last time I wrote a post in this series it was looking at upgrading some of the hardware that I have. This time it is looking at task separation, or in another way, using mediapc to do some stuff like I have looked at previously. This keeps coming up because I have four computers and…

Qgis functions for labels
One of the great things about Qgis is being able to use expressions in a range of things. This is just a little bit about using a function to combine various fields together to make a caption on a label of a feature. In NZ Rail Maps I have features called Locations which are a…

Computing resources optimisation [2A]
So after a couple of months ago when I did some resource optimisation with my existing computers, it’s time to look at the next stage. That stage will be upgrades to enable all four computers to be used for the most stuff they can. The plan I am considering at the moment (subject to resourcing)…

Graphics issues with map mosaics [3]
Continuing from the previous post in this series. Once you have made up some mosaic tiles you need to know how to edit the sidecar files. In this case with the map tiles that come from LDS there are three sidecar files alongside the actual image. We only need to concern ourselves here with the…

Graphics issues with map mosaics [2]
As I wrote in my last post there are problems when you have to scale down imagery significantly. So I am working on a new map mosaic experiment to see what I can do with it. Starting from four tiles at 0.4 metre resolution i.e. 1 pixel measures 0.4 metres on one side, I am…
