Ways to remap caps lock to control on Windows 10

These methods in this gist worked for me on my U.S.-based keyboard layouts. I am unsure about other layouts. If you have problems, revert your changes; delete the registry key you created (and reboot).

Update: you should probably scroll down to approach 4 where I suggest using Microsoft PowerToys Keyboard Manager.

Approach 1. Manually through regedit

Navigate to and create a new binary value in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layout named Scancode Map.

Comparative Benchmark Numbers @ Rackspace

I've taken the benchmarks from Matthew Rothenberg's phoenix-showdown, updated Phoenix to 0.13.1 and ran the tests on the most powerful machines available at Rackspace.

Results

Framework	Throughput (req/s)	Latency (ms)	Consistency (σ ms)

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

1. Your class can be no longer than 100 lines of code.
2. Your methods can be no longer than five lines of code.
3. You can pass no more than four parameters and you can’t just make it one big hash.
4. When a call comes into your Rails controller, you can only instantiate one object to do whatever it is that needs to be done. And your view can only know about one instance variable.

You can break these rules if you can talk your pair into agreeing with you.
