Open Policy Agent to manage policy for Kubernetes with GateKeeper.
Category: Internet & Culture
Category: Internet & Cloud. This brand new thing: Internet & Cloud. Even though the technology is around for way more than 30 years, it is a never drying source of news and discoveries. The new channel of communication created a entirely new culture and created new businesses, fueling innovation and creativity.
All those things that clearly relate to something ‘new media’, items and thoughts that would not have been possible without the internet, will go here.

Enable Kubernetes in Docker Desktop So, you know you want to run your application in Kubernetes but don’t know where to start. Or maybe you’re getting started but still don’t know what you don’t know. In this blog you’ll walk through how to containerize an application and get it running in Kubernetes.This walk-through assumes you are a developer or at least comfortable with the command line (preferably bash shell).

Net Defender CloudFlare Goes Down, Taking Many Websites With It
The Internet was built with de-centralized infrastructures in mind. To scale globally, network providers like CloudFlare have emerged, to run decentralized infrastructures and offer them as a service. In general, keeping service independent of each others and maintaining heterogeneous networks have a proven track record of resilience, that is not necessarily inherent to the architecture of these providers. Just like Akamai had a bad day in 2004, CloudFlare today suffered from a global outage, that left many obvious collateral problems visible all over the Internet. Bloomberg, among others, reports:
CloudFlare Inc., an internet service meant to protect websites from going down, faced its own network issues on Tuesday, leading to several prominent sites — like blogging platform Medium and video game chat provider Discord — being unavailable for some time.

Behavioral advertising efficiency
Researchers from U Minnesota, UC Irvine and CMU took a look into “behavioural based advertisement”, a segment that requires heavy tracking of users across websites through cookies. A report of their findings is here: Online Tracking and Publishers’ Revenues: An Empirical Analysis. Money quote:
Empirical analysis of behavioral advertising finds that surveillance makes ads only 4% more profitable for media companies They found that despite the 40% “ad-tech” premium charged by behavioral ad companies, the ads only added about 4% the media companies that published them, meaning that behavioral advertising is a losing proposition.

McDonalds safes bees.
O_O.
McDonalds safes bees. With the McHive. To give some tribute to the stereotype, we need to hope not all bees become bumblebees now.
The McHive is keeping bees safe.

Google Cloud Is Down
Apparently Google was down the other day. Unfortunately, I was on a train in a really remote location and couldn’t verify what I picked up from Hacker News and tweeted.
Meanwhile, there is a bit of broader coverage on Slashdot and The Verge, that hint at the size of the outage.
Again, an outage like this reminds of the issues that remain with the Cloud, the difference to traditional infrastructure is merely scale at which an outage hits.
