Yesterday I wrote about a way to do light mode screen recording to convert to light mode from dark mode with ffmpeg. I was wondering if it could be done entirely on the front end for web applications. Turns out you can. I’m sure there are limited wikis and site builders that don’t allow adding style like this, but it works if you can.

    style="filter: invert(1) hue-rotate(180deg) contrast(1.2) saturate(1.1);"

0 deg hue rotate

90 deg hue rotate

180 deg hue rotate

270 deg hue rotate

I saw this tip from Cassidoo and had to try it out for myself. I kicked on a screen recording right from where my terminal was, converted it, and it actually looks pretty good.

ffmpeg \
   -i screenrecording-2026-01-01_10-10-49.mp4 \
   -vf "negate,hue=h=180,eq=contrast=1.2:saturation=1.1" \
   screenrecording-2026-01-01_10-10-49-light.mp4

There are a few unsettling things about it, but overall I feel like it was a success.

--name-status is a great way to see what files have changed in a git diff alongside the status code. I recently used this in a script to create a report of new and modified files during a build.

git diff --name-status
git diff --name-status origin/main
git diff --name-status --staged
git diff --name-status 'HEAD@{3 days ago}'

I learned to today that setting MEMORY on your minecraft server causes the JVM to egregiously allocate all of that memory. Not setting it causes slow downs and potential crashes, but setting INIT_MEMORY and MAX_MEMORY gives us the best of both worlds. It is allowed to use more, but does not gobble it all up on startup.

In this economy we need to save all the memory we can!

Here is a non-working snippet for a minecraft server deployment in kubernetes.

      containers:
        - name: dungeon
          image: itzg/minecraft-server
          env:
            - name: EULA
              value: "true"
            - name: INIT_MEMORY
              value: "512M"
            - name: MAX_MEMORY
              value: "3G"

and in docker compose

  dungeon:
    image: itzg/minecraft-server
    environment:
      EULA: "true"
      INIT_MEMORY: "512M"
      MAX_MEMORY: "3G"

I found snow-fall component from zachleat, and its beautiful… to me. I like the way it looks, its simple and whimsical.

Install #

There is an npm package <a href="https://zachleat.com" class="mention" data-name="Zach Leatherman" data-bio="A post by Zach Leatherman (zachleat)" data-avatar="https://screenshot.11ty.app/https%3A%2F%2Fwww.zachleat.com%2Fopengraph%2F%3Fpage%3D%252F%26cache%3D_p1792265522111/opengraph/" data-handle="@zachleat">@zachleat</a>/snow-fall if that’s your thing. I like vendoring in small things like this.

curl -o static/snow-fall.js https://raw.githubusercontent.com/zachleat/snow-fall/refs/heads/main/snow-fall.js

I generally save it in my justfile so that I remember how I got it and how to update…. yaya I could use npm, but I don’t for no build sites.

get-snowfall:
    curl -o static/snow-fall.js https://raw.githubusercontent.com/zachleat/snow-fall/refs/heads/main/snow-fall.js

Usage #

Now add the component to your page.

<!-- This belongs somewhere inside <head> -->
<script type="module" src="snow-fall.js"></script> <!-- Adjust the src to your path -->

<!-- This belongs somewhere inside <body> -->
<!-- Anything before will be below the snow. -->
<snow-fall></snow-fall>
<!-- Anything after will show above the snow. -->

Today I learned an important lesson that you should periodically check on your kubeconfigs expiration date. It’s easy to do. You can ask for the client-certificate-data from your kubeconfig, decode it, and use openssl to get the expiration date.

kubectl config view --raw -o jsonpath='{.users[0].user.client-certificate-data}' \
  | base64 -d 2>/dev/null \
  | openssl x509 -noout -dates
