V Ecosystem

Six lab stations cover my work across the V ecosystem — the compiler core, scientific computing, tensors and autograd, reactive streams, CI tooling, and the community catalog. Each station pairs a working diagram with the verified role, repository, and license behind it.

Selected V ecosystem projectsThree separate project areas: VSL for scientific computing, VTL for tensors and autograd, and RxV for reactive streams. The lines group projects in one ecosystem and do not indicate dependencies.

V language

Compiler → standard library → tooling.

Three concentric rings place the V compiler at the center, surrounded by the standard library and tooling.Vstdlibtooling

VSL

Shape a sampled signal, then inspect its frequency bins. This browser model demonstrates the math; it does not run VSL.

VSL signal and discrete Fourier transformA synthetic 64-sample signal combines a 5-cycle fundamental with a 10-cycle harmonic. Its discrete Fourier transform has peaks at bins 5 and 10.
x[n] = sin(2π · 5n/64) + 0.45 sin(2π · 10n/64 + π/4)64 samples · dominant bins 5 and 10

Small screen · scroll the plot horizontally to inspect every frequency bin.

Static preview · 64 samples · peaks at bins 5 and 10.

The static plot above shows a 5-cycle fundamental and its 10-cycle harmonic. Enable JavaScript to change the frequency and run the transform.

VTL

A tiny autograd graph. Send values forward; send gradients back.

  1. INPUT TENSORSx · ∂L/∂x = ww · ∂L/∂w = x
  2. RECORDED GATE× multiply
  3. OUTPUT TENSORy = xwLOSS GRADIENT · ∂L/∂y = 1
An illustrative graph computes y equals x times w. Forward values flow from x and w through multiply to y. Reverse mode starts with dL over dy equals one and returns gradients dL over dx equals w and dL over dw equals x.TENSORxTENSORwGATE×OUTPUTy = xwxwxw∂L/∂y = 1∂L/∂x = w∂L/∂w = x

Illustrative graph · y = x × w and L = y · symbolic values, not a runtime trace

Forward pass ready. Run it to follow tensor values from inputs to output.

VTL · MIT — pure-V tensors with autograd (needs VSL for LA backends)

Beta tensor, reverse-mode autograd, and neural-network library backed by VSL.

RxV

Reactive streams. Emit once, then stop — replay to see again.

A horizontal event timeline receives a burst of emitted stream values.

Static preview. Enable JavaScript to emit a demo burst.

ReactiveX implementation for V with generic observables, channel pipelines, and composable operators.
