AWS Serverless Chatbot Hackathon

Last month me and two buddies from work, Michael Diender and Stephen Shim, participated in AWS Serverless Chatbot Hackathon hosted by Devpost. This hackathon was announced by Jeff Barr on AWS Blog on August 10th this year. Even though they allowed about 1.5 months submission period, our team only spent 8 hours for each person in order to build two entries due to our busy schedules: Chaos Slackbot and SiteChecker Slackbot.

Due to lack of coding time outside of work hours, I’ve handed some projects over to these intrepid volunteers: Repoman is now maintained by Bastian Krol SiteMonitor Plugin is now maintained by Francisco Hernández Suárez Some other Jenkins plugins had organically been inherited by the community: ChuckNorris Plugin with Baptiste Mathus NodeJS Plugin with Nicolas De loof Thanks, folks! Much appreciated. And just as a reminder, all of the Jenkins plugins I created eons ago are up for adoption.

Custom AWS AMIs Dependency Tree

As awesome as those AMIs from AWS Marketplace are, it’s often not possible to use most of them AS-IS at various organisations due to policies that enforce: Mandated operating system with specific distro and version Blacklisted operating system packages for security reasons Whitelisted versions of various tech stacks, tools, libraries, etc I’ve never found a marketplace AMI that fulfils all of the above requirements without some further provisioning, which can sometimes defeat the purpose of using an AMI in the first place.

My Ninja Blocks Setup

Now that the fine folks at Ninja Blocks already started shipping their next generation IoT controller, the Ninja Sphere, I better write about my old school Ninja Blocks setup before it gets too late. First off is the Watts Clever socket that I used with Ninja rules to switch a table lamp on at 8.30pm and then switch it off at 10.30pm during weekdays. The second socket is used to switch my Tivoli radio on and off on the rare occasion when everyone is away travelling and the house is empty, you know, like Home Alone but minus the kid.

Wrapping AEM cURL Commands With Python

If you ever had the experience (no pun) of using Adobe Experience Manager (AEM), you would already know that curl commands are arguably the de facto way of interacting with AEM over http. Whenever you google for various AEM /CQ HOWTOs, it’s easy to find examples with curl commands: Adobe CQ- Is it possible to execute CURL command? How to create pages using curl command in CQ / WEM

Human-Readable Ansible Playbook Log Output Using Callback Plugin

One problem I’ve had with Ansible playbook since its early 0.x days is with its verbose log output. Jsonified by default, it’s hard to read, and pretty much impossible for a human to review when its stdout or stderr contains tens/hundreds of lines combined into one lengthy string. Here’s how it looks like: changed: [gennou.local] = {"changed": true, "cmd": "/tmp/sample.sh", "delta": "0:00:00.019164", "end": "2014-03-30 21:05:33.994066", "rc": 0, "start": "2014-03-30 21:05:33.974902", "

A few weeks ago I participated in Node Knockout 2013 (NKO4), a 48-hour hackathon with 385 teams competing for the top spot in 7 categories (team, solo, innovation, design, utility/fun, completeness, and popularity). And here’s a video of what I hacked: Roombox, a Roomba vacuum cleaner turned into a boombox using node.js . This demo shows the Roomba playing Rocky theme, Beverly Hills Cop theme, Hey Jude (The Beatles), Scar Tissue (Red Hot Chilli Peppers), Super Mario Bros.

NodeUp 53: NodeUp Listeners On NodeUp

About a month ago, I joined D-Shaw, Nizar Khalife, Erik Isaksen, and Matt Creager on NodeUp 53 where we discussed about NodeUp podcast and node.js community from NodeUp listeners point of view, and I also talked a bit about Australia, kangaroos, and node. Thanks to Rodd Vagg for pinging me about this particular episode. Recording the show itself was an interesting experience :). For one, it started at 4am Melbourne EST.

An Old Dryer, A Watts Clever, and A Ninja Blocks

This was another quick weekend hack to fix my old dryer’s busted timer problem (busted timer = having to stay around when it’s time to switch off the dryer). Step one was to use Watts Clever Easy-off Remote Control Socket which allowed me to switch the power on and off remotely. This product comes with a remote control which saved me from having to get out of the house to get to the garage during winter.
