Triggering ECS RunTask from AWS CloudFormation

Inevitably there will come a time where you’re deploying an application on Amazon ECS and you’ll need to fire a single-run command on deployment. This could be something like a database migration or something else that sets up your environment post-deployment that can’t, or shouldn’t be run within your container’s startup sequence (by using entrypoints/bootstrap scripts). You’ll be using CloudFormation (as you should) and you’ll stumble across a bit of an issue..

Creating users in PostgreSQL

This one has thrown me one too many times, and short of a better place to note this sequence of commands down, I’m posting it here.

Dell Inspiron 5558 Review

I’ve never done a hardware review before (with the exception of the odd Amazon review), so bear with me.

For those who’ve been following my rarely updated blog, I’ve been plagued with laptop issues for a while (here, here, here and here – oddly enough all LCD related) so I figured it was about time I found some sort of reliable work horse that I can just *get stuff done* rather than having to faff around with hardware every handful of months (the last post about LVDS cables covers a significant period of time, and recently started playing up again). So it was about time for a change.
