Is dnsdock the answer?
Third time lucky on my quest to solve Docker container linking issues.
I've struggled with Docker, and getting it to play nicely with our workflow, principally around the issue of container IP resolution at runtime:
the linking of containers only works if it is done in the correct order. If you decide to restart / rebuild your database container (for instance, to reset the data to a known . . .
Spolksy - Man with a Mission
Nice guys do sometimes win
[tl;dr Go and read Joel Spolsky's own blog post - quotes printed here are taken from there without explicit permission.]
Joel Spolsky is a man who set out with a simple goal - "make a company where the best developers want to work" - and has in the process created two of the best known (amongst their target audience) . . .
It doesn't do what you think it does, but it can still be useful.
I've you ever need to store lists of IDs in a field in Django, you've probably
come across the CommaSeparatedIntegerField. It sounds ideal - you can save
lists to and from the database. Brilliant.

Go, go, go...
What would Murray Walker do?
Seems like the buzz around Go over the last couple of years since its 1.0 launch hasn't just been hot air. There were a couple of high profile projects such as Cloudflare's Railgun back in 2012/23, which many (inc. myself) suspected may have been at least partially sponsored / encouraged by Google themselves to get #golang into the . . .
Is DNS the new HTTP?

What we did in the aftermath of Heartbleed
Last Tuesday (8th April) we had a period of unexpected downtime on the site (from 8pm BST). This turned out to have been caused by Heroku (our hosting platform) resetting their SSL certificates in response to the now infamous Heartbleed bug. (One of the advantages of using a platform like Heroku is that you have the people on top of these . . .
Is Skydock Fig's missing link?
Runtime DNS resolution of Docker container IP addresses.
Three months ago I wrote an article entitled "Is Fig Docker's missing link?" It wasn't, quite, and I abandoned my attempt to move off of a single Vagrant VM and onto a super-clean Docker-powered development environment. My discovery of Skydock has reeled me back in.
First, some background - my experience of getting . . .
