  • Domain groups: geositeDirectGroups and geositeProxiedGroups
    • geositeDirectGroups is initialized with cn and geolocation-!cn@cn.
    • geositeProxiedGroups is initialized with geolocation-!cn.
  • To switch between different modes, modify the geositePreferDirect property in gui-config.json
    • When geositePreferDirect is false (default), PAC works in whitelist mode. Exception rules are generated from geositeDirectGroups. Unmatched domains goes through the proxy.

3. PowerShell

A cross-platform task automation and configuration management framework, consisting of a command-line shell and scripting language. Unlike most shells, which accept and return text, PowerShell is built on top of the .NET Common Language Runtime (CLR), and accepts and returns .NET objects. This fundamental change brings entirely new tools and methods for automation.

GitHub logo PowerShell / PowerShell

PowerShell for every system!

Welcome to the PowerShell GitHub Community PowerShell Core is a cross-platform (Windows, Linux, and macOS) automation and configuration tool/framework that works well with your existing tools and is optimized for dealing with structured data (e.g. JSON, CSV, XML, etc.), REST APIs, and object models It includes a command-line shell, an associated scripting language and a framework for processing cmdlets.

Windows PowerShell vs. PowerShell Core

Although this repository started as a fork of the Windows PowerShell code base, changes made in this repository do not make their way back to Windows PowerShell 5.1 automatically This also means that issues tracked here are only for PowerShell Core 6 and higher. Windows PowerShell specific issues should be opened on UserVoice.

New to PowerShell?

If you are new to PowerShell and would like to learn more, we recommend reviewing the getting started documentation.

10. WaveFunctionCollapse

Bitmap & tilemap generation from a single example with the help of ideas from quantum mechanics


This program generates bitmaps that are locally similar to the input bitmap.

main collage

main gif

Local similarity means that

  • (C1) Each NxN pattern of pixels in the output should occur at least once in the input.
  • (Weak C2) Distribution of NxN patterns in the input should be similar to the distribution of NxN patterns over a sufficiently large number of outputs. In other words, probability to meet a particular pattern in the output should be close to the density of such patterns in the input.

In the examples a typical value of N is 3.

local similarity

WFC initializes output bitmap in a completely unobserved state, where each pixel value is in superposition of colors of the input bitmap (so if the input was black & white then the unobserved states are shown in different shades of grey). The coefficients in these superpositions are real numbers, not complex numbers, so it doesn't do the…
