Couple of weeks ago I was fortunate enough to visit Delhi and spend a week with my colleagues Umang, Gaurav and Tom. We had an excellent and productive week and in between development discussion Umang was kind enough to drive us to many fascinating and beautiful places - not least of all to enjoy a wonderful meal at his sister's house.

We worked out of Awfis co-working, which I recommend.

I feel lucky to have seen Delhi this way.

I am trying to teach myself sci-fi style vector painting and this a piece that I think meets the post-on-blog standard.

I tried to copy the basic palette/mood/style of this image.

OMG Not Another TODO List Application

My wife and I needed a collaborative shopping list that we could update from our phones. There are proprietary solutions to this but after some research I was surprised to discover that there is no Free Software application that meets the following criteria:

  • Web based.
  • Easy to deploy.
  • Self-hosted & FLOSS.
  • Allows multiple people to update a list.
  • Simple text based format for easy editing.
  • Mobile friendly - "Add to Home Screen" webapp.
  • Satisfies the single use-case of collaborative TODO editing.

Of course I built one with ClojureScript.

We've been using this "in production" for 3 months and so far it fills our need without issue.

  • Authentication can be accomplished with a .htaccess file or similar.
  • The text-file format is designed so that you can edit lists with a text-editor directly if you want to.
  • If you want to support multiple users you can set up two instances in two different folders and symlink the textfile of the list you want to share between them. Each folder can have its own authentication.
  • You can also do other textfile things like make a symlink into a Syncthing folder which enables you to modify your TODO lists on your laptop or server as well as through the web app.

The realtime updating is accomplished via long-polling. Primarily I used this instead of websockets because when it comes to browsers, older tech is more robust to different operating environments than newer tech.

I resorted to using PHP for a very lightweight server backend because it has the property that basically anybody with web hosting is able to upload a PHP script and I think it's good to give software as egalitarian a deployment surface as possible. Luckily it is only 150 lines of not-too-painful PHP.
