limitLoop.js - limit the frame-rate when using requestAnimation frame
Released under an MIT license.

When to use it?
----------------
A consistent frame-rate can be better than a janky experience only 
occasionally hitting 60fps. Use this trick to target a specific frame-
rate (e.g 30fps, 48fps) until browsers better tackle this problem

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style

Common Options

-#, --progress-bar Make curl display a simple progress bar instead of the more informational standard meter.

-b, --cookie <name=data> Supply cookie with request. If no =, then specifies the cookie file to use (see -c).

-c, --cookie-jar <file name> File to save response cookies to.

I recently ran into an issue of MongoDB shell commands not working. The error message was:

Invariant failure !driverName.empty() && !driverVersion.empty() && !osType.empty() && !osName.empty() && !osArchitecture.empty() && !osVersion.empty() src/mongo/rpc/metadata/client_metadata.cpp

I ran an strace on the mongo command and saw it was trying (and failing) to open the following files:

#!/usr/bin/env sh

# AWS cli delete empty cloudwatch log groups

    --query 'logGroups[?storedBytes == `0`].logGroupName' --output text | \
