  • 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…

  • 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…

  • 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…

  • Firefox Developer exhausts system resources

    One week after reinstalling mainpc I had a repeat of the situation that caused the reinstallation. Firefox Developer, which is the main browser I use, somehow got into a situation where it was using full CPU, RAM and swap for a period. I use the KDE system load monitor widget on the panel to monitor…

  • NZ Rail Maps: Optimising Gimp and using 4x4x4 grid for mosaics [1]

    As recent posts have outlined I am using a new grid system for the NZ Rail Maps mosaics to standardise on the use of 4800×7200 tiles for historical aerial images, because Qgis limitations means it tends to run out of memory exponentially more rapidly and be much slower to update the screen if larger sizes…

  • How to optimise Gimp resource usage

    Since I have one computer for the NZ Rail Maps project that is mostly used just for Gimp for mosaic creation and as it has got 32 GB of RAM and 100 GB of Linux swap on a partition of the SSD I need to make sure it uses the available system resources efficiently. One…

  • General update 2019-02-15

    Last week I had some issues with mainpc resulting in it running out of /tmp space which of course is caused or impacted by running out of space on the install volume and caused a number of user files in /home I was working on to become corrupted. I haven’t looked at the bigger question…
