Why I love zsh (and hate being forced to use bash)

• Smarter completion. A few examples:
• context sensitive -- if you have file "name1" and directory "name2", "cd nam<TAB>" completes to "name2/"
• "tar xf <TAB>" completes to tarballs only. "unrar x <TAB>" completes to RARs only. etc.
• rsync / scp completion: "rsync host:anything/<TAB>" shows you files on host under anything/
• also works with rsync:// URLs
• SSH host completion from ~/.ssh/config & ~/.ssh/known_hosts
• lots of other smart completions: Rake tasks, git commands & SHAs, dpkg packages, dash-options for most commands, etc etc.

Upload a file with $.ajax to AWS S3 with a pre-signed url

When you read about how to create and consume a pre-signed url on this guide, everything is really easy. You get your Postman and it works like a charm in the first run.

Then you open your browser, try your usual $.ajax() and send your PUT operation, and you hit the cold iced wall of AWS error message, a simple <Code>SignatureDoesNotMatch</Code> that will steal hours from your productivity.

So here I come to save you and give you a free working example of how to upload a file directly to AWS S3 from your browser. You are wellcome :).

Using Git to Manage a Live Web Site

Overview

As a freelancer, I build a lot of web sites. That's a lot of code changes to track. Thankfully, a Git-enabled workflow with proper branching makes short work of project tracking. I can easily see development features in branches as well as a snapshot of the sites' production code. A nice addition to that workflow is that ability to use Git to push updates to any of the various sites I work on while committing changes.
