from The Missing Column That Didn't Crash

Compute content fingerprints and see why filenames are labels, not identity.

from Checksum, Not Filename

Shift logical dates and watch today-relative attributes mutate old records.

from Your Date Dimension Is Not Static

Compare usable capacity, write penalties, and fault tolerance across ZFS, BTRFS, and LVM.

from ZFS, BTRFS, and LVM in the Homelab: Picking a Filesystem Without Regret

from The Keys That Never Matched

Enter a recipe and see whether its effective fat-to-flour ratio is physically plausible.

from You Can Check a Cookie

Sorting, Fourier, gravity, reaction–diffusion, boids, and other small things to watch and tweak.

Link a 3D feature cloud to its 2D principal-component projection and see why feature standardization changes the result.

Move an optimizer across a 3D loss surface and the matching 2D contour map, one step at a time.

Assign points, move centroids, and change initialization across linked 2D and 3D cluster views.

Connect simulated portfolio paths and terminal outcomes to a 3D volatility-and-horizon risk surface.

Turn angular projections into a sinogram, reconstruct a slice, and inspect the matching 3D acquisition geometry.

Orbit a reconstructed scene while a linked debug view reveals its depth-sorted anisotropic Gaussian footprints.

Compare PCA with a nonlinear neighborhood map across the same original 3D manifold and reduced 2D embedding.

Connect a WebGPU-driven 3D particle volume to its top-down density heat map and sampled force field.
