python-mock and autospec

Sometimes, code I write initially is very much part of the discovery process. Initial attempts will be scrapped and refactored aggressively until I begin to settle on the overall structure and design of the application. At this point I will begin retroactively writing tests for existing code and switching to a more test-driven design approach for new code.

Unfortunately, I've been bitten a few times when using python's mock library by misunderstanding of the pitfalls around autospec defaulting to false, as

diffing with diffr

colordiff produces diffs that are not always easy to read when a patch has many whitespace changes or minor changes to each line. An upgraded diff tool, such as diffr, can help.

Networking from guest to host in a virtual machine

prereqs & assumptions

1. linux guest
   • I used manjaro but it shouldn't matter which distro
   • ssh client with an ssh key in /home/user/.ssh
   • Optional: mosh
2. macos host (this probably works more or less the same way with a linux host also though)

• sshd on the host, accessible by the guest

This works in android-studio 4.0.

1. In the menu, Tools -> AVD Manager
2. Create an Android Virtual Device (AVD). Consider compatibility issues when choosing which sort of machine to create. Some apps are not compatible with tablets, for instance.
3. DO NOT OPEN THE AVD.
4. Navigate to the configuration files for the AVD. On my system this was $HOME/.android/avd/my_avd.avd
5. Edit config.ini. Find the setting PlayStore.enabled and change the value to true.
6. For good measure I also did this in hardware-qemu.ini but I'm not certain that that is required.
7. Now you can start the AVD. The Play Store will be available on first boot up.

How Median-Buchholz tie breaker works.

Assumptions:

1. We are talking about 2 different players, P1 and P2.
2. They each played 6 rounds.
3. They each won 4 of them and lost two of them (i.e. they're tied).

After all 6 rounds, the opponents for P1 ended up with the following track record:
