Making a big image zoomable

When you have a giant image and you want to make it easy to pan and zoom without downloading the whole 50MB image into someone's browser, a nice workaround is to cut that image into tiles at different zoom levels and view it as it were a map. An example where I've used this technique is The "Snowpiercer" Scenario.

One way to cut your big image into the requisite tiles is with gdal2tiles.py.

Alternatively, this Node script will do the cutting after you install node-canvas and mkdirp:

const fs = require("fs"),

Kiosk Mode macOS

Create two user accounts
- Administration account
- Kiosk Account - This account will be locked down with Parental Controls
Set up remote management
- We are using Screens 4
- See Screens documentation Configuring macOS for Remote Access
Install kiosk software

We use a role-based Apple ID (ex: webmaster@[institution].org) to manage macOS software. Managing Apps this way saves lots of headaches.

Software

Mainboard firmware: Marlin 2.0.9.2 (fork with config, see Marlin/Configuration{,_adv}.h)
- diff: nvim -d {Marlin,config/Artillery/Genius}/Configuration.h, same for Configuration_adv.h
  - mostly calibration, new extruder and noise-free PWM for parts fan
  - LIN_ADVANCE instead of S_CURVE_ACCELERATION (don't work together)
- before 13.11.2020: Marlin 2.0.5.3 (3dprintbeginner) (branch)
TFT firmware: artillery_tft_fw_1.27.x_patch_9.2 (digant@thingiverse) (TFT-config.ini)
- Put in Marlin mode (long press, persists on reboot) when printing with OctoPrint because TFT shares serial connection.

Convert your WebM to ProRes

Like many of you lucky enough to purchase a PS5, I have been enjoying my time with the new console. One feature I started playing with is the video game capture feature via the "Create" button. I have been capturing my favorite clips here and there and selected the best ones to include a video I want to share. Unfortunately, I ran into trouble. None of my video editing applications (FCPX, DaVinci) support the WebM container. My favorite clips were all captured using WebM.

If you like me have all your favorite clips stuck in WebM then I have a solution for you. FFmpeg! This free software includes a ProRes encoder that simple enough to use works on Davinci Resolve (free version available) and Adobe Premiere! (FCPX of course supports ProRes.) See links below.

MacOS (and Linux)

On the MacOS, you can use the following command (Bash) to convert all WebM files in the current directory to ProRes.
