How to setup a development environment where Git from WSL integrates with native Windows applications, using the Windows home folder as the WSL home and using Git from WSL for all tools.

Note if using Git for Windows, or any tool on the Windows side that does not use Git from WSL then there will likely be problems with file permissions if using those files from inside WSL.

Tools

These are the tools I use:

• git (wsl) - Command line git from within WSL.
• Fork (windows) - Git GUI (must be used with wslgit)
• wslgit - Makes git from WSL available for Windows applications. Important! Follow the installation instructions and do (at least) the first optional step and then the Usage in Fork instructions.

Broken Image Repairer

What is the problem?

A long time ago, it was possible to inline images from all kinds of external sources. Since the switch from HTTP to HTTPS, this is no longer possible; only HTTPS sources are allowed. This leads to ugly blurbs like

alt text http://example.com/image.png

instead of a nicely formatted page with images. Sometimes, the links don't even work anymore, even with HTTPS images, which will show like this: ... Luckily, we have the Wayback Machine which is able to rescue some of the lost images. Since a picture often says more than a thousand words, it's important to bring back the post into its original state; important enough to justify the occasional bump of an old post (see below).

I've been deceiving you all. I had you believe that Svelte was a UI framework — unlike React and Vue etc, because it shifts work out of the client and into the compiler, but a framework nonetheless.

But that's not exactly accurate. In my defense, I didn't realise it myself until very recently. But with Svelte 3 around the corner, it's time to come clean about what Svelte really is.

Svelte is a language.

Specifically, Svelte is an attempt to answer a question that many people have asked, and a few have answered: what would it look like if we had a language for describing reactive user interfaces?

A few projects that have answered this question:

# I've found that the "Migrate to AndroidX" converter in Android Studio doesn't work very
# well, so I wrote my own script to do the simple job of converting package names.
#
# You can download a CSV of package names here: https://developer.android.com/topic/libraries/support-library/downloads/androidx-class-mapping.csv
#
# It'll run faster on a clean build because then there are fewer files to scan over.
#
# Uses `gsed` because I'm on a Mac. Can easily replace with `sed` if you don't have `gsed`.

The PATH is an important concept when working on the command line. It's a list of directories that tell your operating system where to look for programs, so that you can just write script instead of /home/me/bin/script or C:\Users\Me\bin\script. But different operating systems have different ways to add a new directory to it:
