Long-form

The right way to override any highlighting if you don't want to edit the colorscheme file directly

Generalities first

Suppose you have weird taste and you absolutely want:

your visual selection to always have a green background and black foreground,
your active statusline to always have a white background and red foreground,
your very own deep blue background.

exFAT support on macOS seems to have some bugs because my external drives with exFAT formatting will randomly get corrupted.

If Disk Utility is unable to repair, consider trying this:

In Disk Utility, ensure that the drive is not mounted, eject it if it is mounted.
Use diskutil list to find the right drive id.
You want the id under the IDENTIFIER column, it should look like disk1s1
Run sudo fsck_exfat -d <id from above>. eg sudo fsck_exfat -d disk1s3
-d is debug so you'll see all your files output as they're processed.

Semantic versioning regex

^([0-9]+)\.([0-9]+)\.([0-9]+)(?:-([0-9A-Za-z-]+(?:\.[0-9A-Za-z-]+)*))?(?:\+[0-9A-Za-z-]+)?$

Kubectl output options

Let's look at some basic kubectl output options.

Our intention is to list nodes (with their AWS InstanceId) and Pods (sorted by node).

We can start with:

kubectl get no

Vim: pushing built-in features beyond their limits

The situation

Searching can be an efficient way to navigate the current buffer.

The first search commands we learn are usually / and ?. These are seriously cool, especially with the incsearch option enabled which lets us keep typing to refine our search pattern. / and ? really shine when all we want is to jump to something we already have our eyeballs on but they are not fit for every situation:

when we want to search something that's not directly there, those two commands can make us lose context very quickly,
when we need to compare the matches.

Step 1 - Make a Discord Webhook

Find the Discord channel in which you would like to send commits and other updates
In the settings for that channel, find the Webhooks option and create a new webhook. Note: Do NOT give this URL out to the public. Anyone or service can post messages to this channel, without even needing to be in the server. Keep it safe!

Step 2 - Set up the webhook on Github

Navigate to your repository on Github, and open the Settings

	Relay setup

	On the server's instance of weechat:
	/relay add ssl.irc 8001
	/secure set relay WHATEVER_PASSWORD
	/set relay.network.password "${sec.data.relay}"

	On the server, to generate the ssl certificate:

	# I had a bit of trouble getting my unifi controller (hosted offsite) to use a proxy/letsencrypt. So here are the fruits of my labor.
	# The unifi default port is 8443 running on localhost.
