The business case for not needing a business case
You’ve heard these terms a million times: Managed services and software-as-a-service. At first glance, they appear deceptively similar. You wonder, how are they different again? Understanding the difference between them unlocks a perspective on where the telecom industry is heading.
Building a product ecosystem: Here's a question mobile operators need to hear more often.
“Can I book you for a two-hour meeting so we can start sketching out your customer's journey?” This is not a question that a telco operator normally hears.

Manual on Me: Matt Long
As I was waking up this morning, I started surfing Reddit. One post, in particular, jumped out at me. In this post, the writer (OP in Reddit parlance) had been asked to take a personality test at work by a new supervisor. The OP was asking if this was something they should agree to do.

Don't leave a message after the beep
Think quickly: When was the last time you dialed into your voicemail to listen to a message someone had left for you? Chances are, it’s been a while.

A timer is a cornerstone of any software that communicates over the network. There are plenty of implementations that provide a timer facility. Most of them are in memory and will lose scheduled timers should the application crash. In this blog we discuss durable Kafka timers that do not depend on in memory state. By design we shall assume 1 second resolution of these timers.

Forbidden lore: hacking DNS routing for k8s
At WG2 we’re coming close to having everything running in Kubernetes, which means that almost everything we deploy needs to be pulled from a registry. We have run our own local registry for some time now, to host both locally-built images and cached images from Docker Hub.
