Don't use VPN services.

Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

  • There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

how to add more utilities to git bash for windows, wget, make

How to add more to Git Bash on Windows

Git for Windows comes bundled with the "Git Bash" terminal which is incredibly handy for unix-like commands on a windows machine. It is missing a few standard linux utilities, but it is easy to add ones that have a windows binary available.

The basic idea is that C:\Program Files\Git\mingw64\ is your / directory according to Git Bash (note: depending on how you installed it, the directory might be different. from the start menu, right click on the Git Bash icon and open file location. It might be something like C:\Users\name\AppData\Local\Programs\Git, the mingw64 in this directory is your root. Find it by using pwd -W). If you go to that directory, you will find the typical linux root folder structure (bin, etc, lib and so on).

If you are missing a utility, such as wget, track down a binary for windows and copy the files to the corresponding directories. Sometimes the windows binary have funny prefixes, so

Git Subtree Basics

If you hate git submodule, then you may want to give git subtree a try.

Background

When you want to use a subtree, you add the subtree to an existing repository where the subtree is a reference to another repository url and branch/tag. This add command adds all the code and files into the main repository locally; it's not just a reference to a remote repo.

When you stage and commit files for the main repo, it will add all of the remote files in the same operation. The subtree checkout will pull all the files in one pass, so there is no need to try and connect to another repo to get the portion of subtree files, because they were already included in the main repo.

Adding a subtree

Let's say you already have a git repository with at least one commit. You can add another repository into this respository like this:

Best Practices for Clean Code
  1. Use descriptive and obvious names.
    • Don't use abbreviations, use full English words. player is better than plr.
    • Name things as directly as possible. wasCalled is better than hasBeenCalled. notify is better than doNotification.
    • Name booleans as if they are yes or no questions. isFirstRun is better than firstRun.
    • Name functions using verb forms: increment is better than plusOne. unzip is better than filesFromZip.
    • Name event handlers to express when they run. onClick is better than click.
    • Put statements and expressions in positive form.
      • isFlying instead of isNotFlying. late intead of notOnTime.
      • Lead with positive conditionals. Avoid if not something then ... else ... end.
  • If we only care about the inverse of a variable, turn it into a positive name. missingValue instead of not hasValue.
