Upgrading Into the Breach (GOG - for Linux)

I bought Into the Breach on Galaxy of Gaming for linux on release. In July 2022, Subset games released Into the Breach Advanced Edition, [(1)][1] a free expansion of the original. This article details how I upgraded and moved my save game files across to the latest version of the game.

Game save data is stored in files with the names in the foramt: profile_{Name}. [(2)][2]

The first version I installed was GOG v1.0.10 (2-28-2018). This version was run via wine [(3)][3], and installed to ~/.wine/dosdevices/c:/GOG Games/Into the Breach/. The save game files (eg. profile_Alpha) were saved in the top level of this directory.

I installed the latest version of Into the Breach from GOG as of Feb 2023: v. 1.2.86 (10-10-2022). The installer prompted for an install location, with a default of ~/GOG Games/Into the Breach. I chose the default location and let the intaller create a desktop file etc. On install, it was clearly quite different to the old version

Function Register

A Lightweigt function registry implementation.

Eg:

register = Register()

@register("hello")

Function Composition

A minimal compose implementation.

Given a list of functions, apply them squentially to an argument. This is equivalent to:

funcs = [h, ..., g]
compose(x, funcs) == g(...(h(x)))

Mocking HTTP Requests in Click

Simple MVP to test mocking of HTTP requests made in Click commands using the responses library.

In simple_post.py we have a Click command that makes a request to https://httpbin.org, a useful API for testing requests.

In test_simple_post.py we have a test suite which can be run by PyTest. In the first

Installing Python From Source

Installing Python on Linux isn't so hard. These are my notes for installing on Ubuntu.

Install build dependencies using apt.
Choose and download the version of Python you'd like to install from the releases page.
Extract the directory
Run ./configure and make to install

Comparison using the python date format spec to parse RFC-822 date strings vs using dateutil.

Prefect on Dask on K8s

Intro

A "Hello, world!" Prefect flow running on an ephemeral Dask Cluster on Kubernetes.

The Prefect Core docs suggest running flows on a Dask cluster via Dask Distributed and an article from the MET Office Informatics Lab demonstrates running an adaptive Dask cluster on k8s. This example is inspired by those sources, as well as the respective docs for the technologies used.
