你可能其實不懂繼承 - 什麼是 Covariance 跟 Contravariance

在近代高等程式語言快（ㄏㄨˋ）速（ㄒ一ㄤ）演（ㄔㄠ）化（ㄒㄧˊ）的狀況下，很多 strong type 的程式語言都開始有了 generic 的設計， 舉例來說：

（這只是大略分類）

• Mobile: Swift, Kotlin
• Frontend: Flowtype, TypeScript
• 後端語言：Python (pyre), Scala, C#, Java （沒錯！現在連 Java 都有）

# 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`.

How to follow this guide

• Don't type or run anything until I told you so.
• This guide uses linux commands. For windows users, you can use win-bash
  • https://sourceforge.net/projects/win-bash/files/shell-complete/latest/
  • http://win-bash.sourceforge.net/

The problem

I have one computer and two different github accounts. One is for work, the other is for my personal stuff. I can't use the same ssh key twice, so I have to use different ssh key for each of my accounts. How do I do that? How do I switch between these ssh keys?

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

### If $PROFILE.CurrentUserAllHosts doesn't exist, you can make one with the following:
