Why doesn't the example compile, aka how does (co-, contra-, and in-) variance work?
...f I'm understanding your comment correctly, you need to reread the passage starting at the bottom of page 56 (basically, what I think you are asking for isn't type-safe without run time checks, which scala doesn't do, so you're out of luck). Translating their example to use your construct:

app.use('/static', express.static(__dirname + '/static'));
In this situation, you'd put this above router. This avoids processing other middleware/the router if a file is present, but to be honest, I do...
Difference between git checkout --track origin/branch and git checkout -b branch origin/branch
...ck the remote tracking branch origin/branch.
When a local branch is started off a remote-tracking branch, Git sets up the branch (specifically the branch.<name>.remote and branch.<name>.merge configuration entries) so that git pull will appropriately merge from the remote-tracking...
Rebasing and what does one mean by rebasing pushed commits
... see that master and my-branch both contain commits a and b, but then they start to diverge: master contains c and d, while my-branch contains e and f. b is said to be the "merge base" of my-branch in comparison to master -- or more commonly, just the "base". It makes sense: you can see that my-bran...
