Setting up ThinkPad T14s Gen4 in Ubuntu Linux

About

I finally settled on a new personal Linux laptop, and it's the Lenovo ThinkPad T14s Gen 4 w/AMD processor, 32GB RAM, and Low-power 500 nits display.

I had mine shipped with Ubuntu, it comes with (I think) Ubuntu 22.04.01 LTS. It's nice because they set up the BIOS to come with Secure Boot enabled for Ubuntu. Everything works out of the box.

Log Files

Nodes

Control Plane log files

/var/log/kube-apiserver.log - API Server, responsible for serving the API
/var/log/kube-scheduler.log - Scheduler, responsible for making scheduling decisions
/var/log/kube-controller-manager.log - a component that runs most Kubernetes built-in controllers, with the notable exception of scheduling (the kube-scheduler handles scheduling).

The difference between configuration formats, configuration languages, data formats, and programming languages

There is a lot of confusion out there about what different file formats are and how they are intended to be used. Having used a lot of them over the years, I think I can explain their differences, and when and how to use them.

Data formats

A data format is a file format for encoding data. Typically the format is structured to make it easier for machine interpreting & processing.

How to make Hacker News resistant to outages

This is an explanation of how Hacker News could be made resilient against network and infrastructure failures.

Step 1. DNS redundancy

Make sure you use a DNS nameserver provider that has multiple nameservers using multiple cloud hosting providers in multiple regions and zones. For added redundancy, use multiple nameserver providers, replicate your records between them, and make sure each uses different providers/regions.

Point your origin DNS record (origin.mydomain.com) at each of your origins, using CNAMEs or A records. Keep the TTL as low as you can, usually 60 seconds. Since only your CDN should be hitting this host, this shouldn't stress your nameserver. During an outage, one origin can be removed from DNS (if necessary).
