I was really taken up by this timelapse video of a physical scrum board, but unfortunately we had a virtual JIRA board at the time. So using CasperJS/PhantomJS/SpookyJS (headless browser screen capture), NodeJS/Heroku (backend), AngularJS/Bootstrap (fontend), imgur (image hosting) and Uptime Robot (scheduling) I was able to whip up a poor mans timelapse for virtual JIRA boards using only free tiers of services.
Uptime Robot performs a health check on the url /api/projects/take_screenshots every 15 minutes, which is mapped to take_screenshots() function in the projects controller. This function logs into JIRA using CasperJS, navigates to the Scrum/Kanban board and takes a screenshot.
This screenshot then gets uploaded via the imgur.com api and the returned url gets inserted back into mongoDB.
AngularJS retrieves each project with it’s captured screenshot urls to display them in a Bootstrap carousel.
TODO: Create videos from the screenshots and upload to youtube.
This is an open source project, so feel free to fork and send pull requests.
req.uest.info is an open source online debugging tool for capturing and displaying requests from clients in JSON without the need for a server, built using Node, MongoDB, Express, Angular & Socket.io.
The demo http://req.uest.info is currently hosted on Heroku. Simply set your form or application submit url to http://req.uest.info/submit/ and view the submission data.
When a REST request is made to /submit url the node express route/handler re-transmits/pushes the data to all connected clients using socket.io emit.
This message is handled on the client side by the angular socket.io service.
On row click, the data is passed through a json syntax highlighter and displayed.
TODO: Currently requests are visible to all by default, I’m working on allowing logged in users to make private requests from a set of IP addresses. The user authenticating and IP address management is already implemented using MongoDB and passport.js. What’s left is to search for the ip address when a request arrives, then if a match is found, send the request only to the users connected client. (ip address of each logged in client will have to be stored with their socket connection).
Feel free give feedback in the comments below or to submit a pull request/fork.
When a story is ‘done’ and ‘on the bus’, it’s expected to stay that way until go live. When working in a large team that share a code base, it’s common to break each others stuff.
Automated regression testing has long existed in most applications but for many web sites because it’s impossible to write tests to verify if a website was being displayed correctly. Today opensource tools like Wraith, Huxley, PhantomCSS, PhotoBox etc solve this issue using screencapture comparison techneques.
What will this post help me do?
Automate website regression testing for agile teams that use JIRA. This will prevent you from committing code that can undo previously completed stories.
JIRA stories are used to add test URLs. Every team member can view them which help increase test coverage.
This started out as a quick project to interactively showcase my mobile portfolio, but turned into a project on it’s own taking a few days to complete. This allows you to embed a mobile site at any size while maintaining the scale of its contents.

I keep hearing smart watches, wearables, internet of things etc. which got me thinking about the hardware and embedded systems used to create them. As much as I love soldering and reading resister codes I’m ashamed to say the most complicated thing I’ve made was an FM transmitter.
Since I had an Arduino lying around I decided to build a watch to learn more about the hardware side of things. The plan was to build a POC clock using the Arduino and then shrink it to a watch using an ATtiny .
Tor is used by millions around the wold to access information without censorship, government or snooping.
While Tor makes it possible to access censored websites anonymously it is just as easy to host your own anonymous Tor website.
Clone the Vagrant project: https://github.com/chris-gunawardena/tor-hiddenservice-webhost and run
vagrant up for your own Tor hidden/darknet website.
After getting everything to work locally using virtualbox, the next step is usually to deploy to the cloud. The example vagrant file below is for creating a Amazon EC2 instance using the vagrant-aws plugin.
Web development has long been an ad hoc process and the trend has been to clone or download various libraries/frameworks into folders depending on your programming background and never touch them again. Most don’t minify, lint or combine js/css file for the sake of readability and maintainability. Thanks to new developments in web technologies this doesn’t have to be a Friday night argument at the pub along with where to place the opening brackets and how many spaces/tabs should be used for indenting.
