Create a Devuan Source ISO

Tagged as: Computing Notes

Many distributions do not provide a source ISO to match their installation media. Debian provides one, as does Oracle. As far as I know, those are the only two that do that. Since the GPL requires one to redistribute the source code with the program, one needs to possess a copy of that source code [...]

Configuring Secondary Storage on Nextcloud

Tagged as: Computing Notes

It can be difficult to add a secondary storage to Nextcloud if the storage location is a new local drive. Authentication errors abound and leave one unable to use the additional space. To resolve this, add the drive to the system, and use the occ command to add the secondary storage. Add the new drive, [...]

Apostrophe on Linux and the Preview

Tagged as: Computing Notes

Apostrophe on Linux fails to show the preview in some newer operating systems. This occurs because the WebKit backend switched to using hardware acceleration and this does not work for many users. A fix to the launching command works to bring the preview back to Apostrophe, but the same fix will not work for Epiphany. [...]

This is my first attempt at weekly posts. I created an organizational schema and setup the files to begin the work. One of the things this week that I accomplished was the use of Aider to create a rapid prototype of a paired comparison analysis tool that works on the console in any operating system [...]

Fedora 38 freezes up and crashes sometimes when using Gnome on bare metal.  This may be the result of Gnome reliability issues.  In a previous article I detailed creating a massive repo of Fedora 38, and I still have it.  I will not delete the 238GB repo because Fedora 40 is the last one with [...]

T+n time series analysis

Tagged as: Computing Notes

This isn’t stock advice, it’s a data and math project. AAPL is interesting (not investing advice!) from a data perspective. Part of my big data project was the creation of a tool to analyze every symbol regressed on every other symbol for numerous lags. In addition to revealing the vendor’s mangling of data for unknown [...]
