reliability testing

I bought 4 SSD drives. I'm going to open 8 terminals (2 for each drive) to infinitely write to the drives over and over again.

2 terminals writing at the same time:

• 1 for writing zeros to the drive
• 1 for writing random 1's and 0's to the drive

I'm going to let the drives write for anywhere from three to five days 24 hours a day. If the drives are bad then they should fail within that window.

This guide covers

• Migrating from QGIS 2.x to QGIS 3.x
• Installing QGIS 3.x
• Full changelog for a list of new features since QGIS 2.x.

Migrating from QGIS 2.x to QGIS 3.x

1. Keep a backup copy of your QGIS 2.x projects before you attempt to open them in QGIS 3.x.
2. Review what plugins you rely on. I saw in the documentation that not all plugins have been ported to QGIS 3 so you might not be able to use it if you depend on a specific plugin for your work and it isn't available for QGIS 3.

Matrix building in scripted pipeline

In my project, Jervis, it supports Matrix building via YAML using Jenkins scripted pipeline. However, it is quite easy to calculate matrix building using the cartesian product on a list of lists containing maps (the matrix axes).

For user pipelines the following script approvals must be allowed:
