Adding a new control-plane node to an existing Kubernetes cluster

This document is meant to collect information from various sources to serve as a quick and dirty reminder to myself before ending up on lisa.dev

A pair of helper scripts for Factorio blueprint (string) parsing.

Factorio blueprint strings are base64-encoded and zlib compressed JSON. There is a leading 0 which prefixes the blueprint string. Consider:

The preceeding is a base64 encoded blueprint string for a single Small electric pole with no connections or anything else going on.

You will need to find the ParserFunctions and SimpleCalendar extensions and put them in .. You will also need to make the ./html_images and ./db directories

Also note that this is a much older version of Mediawiki than is current. It works for me, but it's up to you if you'd like to use a newer version.

A native, in-app way to restore files would be far better than needing to navigate to and login to select files.

The workflow to create a zip file in the website could be better: I totally get the 500GB limit, but I shouldn't be able to select files >500GB to receive that error, and if I did somehow, it should direct me to create a snapshot from those same files.

The backblaze downloader app requires logging in (with painful 2FA!) for each zip file. I should be able to select multiple zip files and snapshots. It's not really a backblaze "downloader" if it can't download all the things.

Snapshots: This whole process is a goddamn mess. I've tried for a week to fetch snapshots (ranging from multiple 500GB to a two over 3.9TB) and it's simply not gone well, which sucks because each attempt is costing real dollars.

I tried Cyberduck originally as suggested on backblaze website and that resulted in incomplete files and no way to resume. I've tried b2 3.3.0 to "sync" and it resulted in truncated files. I've trie

@lisa User Notification

Hello! You're receiving this notice because you've tagged me, @lisa, on GitHub, likely in error. Lisa is a common first name, and happens to be mine. I use the @lisa username here on GitHub. While being tagged in various repositories is an interesting way for me to discover new projects, it's likely not your intention. Did you mean to tag someone else? Did you mean to use @lisa instead, in a word as word usage?

Next Steps

I'm unsubscribing from this issue, pull request or project so if you meant to tag someone else to notify them, I would recommend that. If you meant to use my user ID as a plain string, without having GitHub notify me, you can do so by wrapping with backticks (the ` character), like so: @lisa.

This week I ran into a pretty weird bug that mashed up a confluence of a number of things:

• Code changes
• Separate, but related project that generates YAML (sigh, yaml)
• JSON marshalling in Go
• Kubernetes CRDs

How these all intertwine centres around the Kubernetes CRD and JSON marshalling.

Say you have a CRD and its API is:
