All in all, Cloud Foundation 4.0 seems to be a solid version upgrade, with a lot of promise. The tight integration between Cloud Foundation and vSphere with Kubernetes, coupled with the other managementment tools already available from VMware should prove to be a solid foundation (pun intended) for anyone looking to provide both traditional virtualization and container workloads in their on-premises datacenters going forward. The problem, in my not so humble opinion, with this is that vSphere with Kubernetes is (for now?) only available through Cloud Foundation 4.0. That is a very limiting form factor for delivery, and something that might just slow the adoption rate for it considerably.

I’m a big fant of Public Key authentication for SSH but I recently ran into an issue after adding my Public Key to a couple of new Linux VMs I use. The problem was that macOS kept asking for the SSH passphrase when connecting to them, which kind of defeats the purpose of using Public Key authentication in the first place. Thankfully, the solution is pretty simple.

vExpert 2020 VMware has just announced the list of vExperts for 2020, and I’m honored to be awarded for the tenth year in a row! That being said, I’m happy to see the list of Norwegian vExperts grow! It wasn’t that many years ago that we were only two (or for the first couple of years, only one!), now the count is at 11!

My audio setup is a old NAD 326 BEE stereo amplifier with a couple of Dali Blue 5005 speakers. I also have a turntable connected to it, and it sounds beautiful. The solution for enabling streaming to an old (but awesome!) amp, was using the Raspberry Pi 3 B+ I had laying around. I added a HiFiBerry DAC+ HAT to it, and enclosed it in a nice little case that also comes from HifiBerry.

Since moving this site over to Hugo back in 2018, I’ve developed a workflow that seems to work pretty well. Given that I see that a lot of others are also moving over to static site generators, and I wasn’t exactly ahead of the curve on it myself, I figured I would try to write up how I work with Hugo and Visual Studio Code on my MacBook to generate content.

Some times there is a need to use custom DNS servers for some domains, in my case specifically for access to the new lab environment we are building at work (more on that later, this is one beefy lab!) One way of doing this, is adding custom DNS servers to /etc/resolv.conf but in macOS you really shouldn’t be editing that file manually, as it often gets overwritten or otherwise edited by VPN clients and such. Thankfully, there is a better way to create persistent and manageable custom domain specific DNS settings.

I recently got a pair of new displays for the office, a couple of lovely Dell U2719DC’s. These offer USB-C connectivity, which is really nice, and makes it easy to connect my MacBook when I’m in the office. Connected to one of the displays is a Logitech Z337 set of speakers with a sub, since there is no built-in speakers in these displays. The problem I had with that setup, is that macOS doesn’t let me easily differenciate between the two as they are named exactly the same, sometimes creating confusion as to which of them should be the sound output to the speakers.

Way back in 2017, the CA/Browser Forum voted on Ballot 193 – 825-day Certificate Lifetimes, which passed. In short, this means that CA issued certificates issued after March 1st 2018 can not have a validity period longer than 825 days. macOS Catalina implements this change, as described in Requirements for trusted certificates in iOS 13 and macOS 10.15. So it’s been a long time coming, but most of us are just now realizing how this affects us.

Warning: This also applies to Self-signed certificates, like the ones issued for VMware vSphere and related solutions, like NSX-T and others, where the default age is 10 years or so.
