Troubleshooting Guide

This is a guide on how one might go about troubleshooting problems with a web application, using tools like console.log(), chrome dev tools, the debugger, and other resources.

Setting up for success

Break a task down into small chunks. Verify each chunk. As you successfully complete a step and validate that the code works, perform a git commit to provide a historical bread crumb trail. This will narrow the scope of a potential error.

Building Offline First Native Web Applications

Creating Offline First Native Web Applications using PouchDB and CouchDB and replication is a nice approach to remove the challenges keeping the client database insync with the server database.

One thing that always comes up is security, and security is very important and should not be taken lightly. Using implementations like JWT or JsonWebToken and external authentication services like Auth0 and StormPath can create a solid pattern to keep your secrets off of your client.

• duplexify - compose a Duplex stream from a Readable and a Writable stream
• pump - pipe streams together and close all of them if one of them closes

How to set your Acer C720 Chromebook to boot to Ubuntu by default.

1. Place your closed laptop on a soft surface, upside down.
2. Use a sharp knife to cut a hole in the warranty sticker (YES THIS WILL VOID THE WARRANTY).
3. Remove the 13 screws with a small phillips head screwdriver (PH1 size works well). Be careful, the screws are very small and will strip easily if you use the wrong size screwdriver.
