And now for something completely different: a Windows desktop application! Open this gist for the code.

This example uses a python wrapper around Wacom's Wintab/Feel driver to read a Wacom stylus input, and draws a representation of it onto a Tkinter canvas. Each circle represents a point, and its radius is proportional to the pressure of the stylus.

To run the application, you will need: a (Wacom?) tablet or a tablet PC, Microsoft Windows (I tried it with 8.1), Python 3.3, cgkit 2, the code from this repo. To actually run it, open a command prompt where you put the python files, then execute:

python test.py

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.

Docker - How to cleanup (unused) resources

Once in a while, you may need to cleanup resources (containers, volumes, images, networks) ...

delete volumes

// see: https://github.com/chadoe/docker-cleanup-volumes

$ docker volume rm $(docker volume ls -qf dangling=true)

$ docker volume ls -qf dangling=true | xargs -r docker volume rm

Custom thunks TL;DR

This smol post assumes you worked on a custom thunk implementation before but no idea how it works, why you're using cursed macros from 1990s etc. If you don't have any programming experience or relatively new to Unreal world, it's likely you might not understand anything from this post, not because concepts are too difficult to grasp, but rather because this post is written for the people who has an understanding of how Unreal works since a while and want to expand their knowledge of custom thunks implementation.

Part 1:

A thunk is a function that you can save and call later, so if you had an array of TFunction<void()>s, you would have an array of custom thunks that you can bind/unbind new function pointers to existing TFunctions.
Custom thunks of Blueprints are the same, they're a fancy array/list of function pointers. Imagine for each node you placed to graph, Blueprints have a place for that node in it's list of custom thunks. For example the + node in Blueprints that

	retain=True の場合は、UI が閉じたとしても state は残って良いはずなので監視はしない。
