NZ Rail Maps: Two different ways to cover a large area in Gimp [1]
In my last post I compared a couple of large Gimp projects I worked on. Both of these cover a significant distance and they use different ways of doing it. It is illustrative to look at those two different ways and consider if one is better than the other. The first way of doing in…

Webcam with Linux [1]
We need to do some livestreaming on Facebook Live for a project I am working on. Using a phone is quick and convenient, but pretty limited unless it is a selfie. So the next option is a webcam connected to a laptop and remotely located from it by a 5 metre cable which lets me…

NZ Rail Maps: Gimp optimisation with SSD works well
A few posts back in label NZ Rail Maps, I commented on how to optimise Gimp to use the swap partition on the computer effectively. I have since been able to prove using a computer with only 8 GB of RAM that it is able to use the SSD to load much bigger images without…

Buster challenges
There have been a few issues I have found using Debian Buster so far. Among them Command shells have a much more limited set of commands that will work all the time. For example blkid is the latest command I have found that will not work in a Bash shell window under KDE (Konqueror). dpkg…

Python Scripting [4B]: Exif Based Image Renaming 2
Today I am going to have a look at Pillow and its interface for reading EXIF data from images. As I mentioned previously, Pillow is a fork of PIL (the Python Imaging Library) and contains capabilities to read and write EXIF data from images. Although there are official documents for Pillow at Readthedocs, it is…

Python Scripting [4A]: Exif Based Image Renaming
This is now a new scripting project I am starting for Python. I need this script to rename all my photos off the camera, replacing the use of IrfanView which I used on my Windows 10 computer. Whilst I still have that computer and the software, I am looking to do something with Python scripting…

Gimp resource usage challenges
Whilst Gimp has been great for the NZ Rail Maps mosaics, one of its challenges has been with the layer group feature. This feature unfortunately does a lot more than just organise layers in the layer list. Apparently it adds extra stuff that you may not need. From my experience I have found the layer…

Autologin with LXQt
Autologin isn’t something I do normally, but on my computer that run LXQt, for what they are used for, it gets the computer up faster so it is useful. If you are using LXQt with SDDM which is the default display manager, it is pretty easy to use. Simply edit /etc/sddm.conf.d/autologin.conf and enter the following…

Life with Buster
Well I rushed to get Buster on most of my computers yesterday and this was mostly straightforward. The exception being of course mainpc which ran out of disk space while running the apt upgrade command due to the number of new packages downloaded and installed. There can be literally thousands of packages needed for an…

Debian Buster Release due soon
Debian Buster (Debian 10) has been in development for the last few years, and it is expected to be released about the middle of this year. As was described in some earlier posts, I have had Buster running on some of my systems in the past, but not in the last year or so. However…
