Checkbox Switch

A simple, gummy little switch thingy. Now accelerated for touch devices! All JS can be removed though and it will still work.

SQS Latency testing

Run this from an ec2 instance in the us-west-1 region.

It will create two queues and feed messages into the first queue with a timestamp, this message will then be read and the difference between the message timestamp and the current time computed and pushed into a response queue. Reading these times will give you the latency between publishing to a queue and receiving the message.

Troubleshooting AWS unauthorized errors in lambda requests

This is mainly for node.js but might apply to other environments. Unsure.

If you are running a AWS Lambda function that calls another AWS service and getting an error about invalid tokens or other access denied errors, do this:

Check IAM

The role assigned to your lambda function will need permission to perform the actions. Check IAM and make sure the role has all the permissions.

JQL Syntax for the Impatient

There are a few JQL syntax bits to get you started:

• AND --- allows you to add qualifiers to a list
• != Thing --- target one thing
• is in (List, Of, Things) --- target a bunch of things (Done, Closed, Resolved) typically
• not in (List, of, Things) --- do not include a bunch of things
• -1w --- relative time. You can also use -1d for day
• "2015/3/15" --- specific dates

intellij javascript live templates

Just a dump of handy live templates I use with IntelliJ. They should also work with WebStorm.

How to

• Go to settings.
• Search for live templates.
• Under the javascript section you should be able to manage your templates.
