Using “code as self-serve”, such as Terraform or Kubernetes, in Platform Engineering is a rather bad idea.

When an HTTP API is too slow to call repeatedly I have seen engineers immediately turn to making the API do more in one unit of work.

Narrow integration tests are tests that only involve very few components, mostly relying on test doubles to simulate external dependencies.

Last year (2019) I spent a fair amount of time thinking about how to grow Tink’s technical platform; how to organise ourselves – alignment vs. autonomy.

UPDATE: Since this blog post was written, I have migrated to another theme.

Recently I was reading the article “Introduction to modern network load balancing and proxying” and I was reminded by something that has bothered, and still is bothering me, about the AWS Load Balancers (ElasticLoad Balancers, or ELBs).

This post is partially related to my previous blog post about Rewind.

I recently read the blog article “Cookieless Cookies” that talks about using ETag for tracking users.

Privacy seem to be a popular discussion these days.

I’m a big fan of matplotlib and tend to use it every time I’d like to plot something.

In my previous post I was giving an example of using AngularJS events.

Lately I’ve been working a lot in AngularJS.

So it’s time to kick off this blog.

So you have an external library foo version 1.0 that you have committed to your Subversion repository together with your code.
