  • Linux has the best filesystem ever 🙂

    I’ve been in the IT industry for something like 30 years (longer if I was to include the time in my secondary education) and in that time I have used a few operating systems, starting with Apple DOS 3.3, UCSD P-System, CP/M, Acorn MOS, Macintosh System 6/7, Netware, MS-DOS, Windows (since 3.1), macOS and Linux.…

  • Lubuntu vs Debian / LXQt

    As we well know my preference is very much the use of Debian rather than Ubuntu. I do this because Debian better supports experienced Linux users like me. Debian however omits firmware drivers for non-free hardware by default which means a lot of fiddling to download and install and there are some other capabilities like…

  • Raspberry Pi 4 Released

    Raspberry Pi Foundation has announced the release of Raspberry Pi Model 4. RPi4 adds a number of new features over the Model 3, including dual HDMI 4K displays (via micro connectors), USB-C power connection, USB 3 ports on board and a choice of 1 GB, 2 GB or 4 GB onboard RAM. There is a…

  • Buster moves to RC1

    I have put a 240 GB SSD into the computer that I edit the map mosaics on (in Gimp) which gives me 200 GB of swap file space so that large projects can be handled more readily. I have no actual intention of going beyond 100 layers as in the present projects; it will be…

  • Using a Raspberry Pi headless

    I have used several different systems that connect to a tethered mobile connection for ministry related activities that shouldn’t be tied to the shared internet connection that I use for most other things, out of respect for the people who own that internet connection and whose IP address is tagged to every activity. What one…

  • Networking / Wireless with Debian LXQt

    There are some issues possible with LXQt if you have Wifi because of limitations in the current Buster install. Some of these may be resolved by the time Buster is released…but not all, for reasons explained below. First issue for Wifi is if the drivers are non-free, as is fairly likely. You’ll notice this at…

  • NZ Rail Maps: Two different ways to cover a large area in Gimp [4]

    Last time I wrote in this series I had been experimenting with the linear and segmented methods of covering a large geographical area in Gimp, such as I do with map mosaics for NZ Rail Maps. In summary the linear method consists of creating a large canvas that can lay out all the tiles in…

  • Gimp resource limits

    Right now I am completing a set of maps covering from Dunedin to Mosgiel, some 17 km of rail corridor continuously mapped. The result is a Gimp file of over 60 GB in size and Gimp itself is using about 150 GB of storage (memory plus swap plus home drive cache) to allow this file…

  • NZ Rail Maps: Two different ways to cover a large area in Gimp [3]

    Last time in this series I talked about my experiments in testing whether Gimp could handle a large canvas size successfully, since this would tend to suggest a linear project for covering a long section of rail corridor (17 km in a current project) could work. If successful this might be a better way of…

  • NZ Rail Maps: Two different ways to cover a large area in Gimp [2]

    Following on from my previous post, in the case of the Dunedin-Wingatui map mosaic Gimp project, I chose to extend the size of the map canvas from 7×7 to 11×7 and bring the tiles for the Wingatui station alongside those of Green Island-Abbotsford. The reason for this was to be able to bring some smaller…
