Tokens & Tracesby Stan Vespie

Welcome to Tokens & Traces


Welcome to Tokens & Traces. This blog is a technical notebook focused on the mechanics of machine learning models, computer security vulnerabilities, autograd engines, and high-performance systems engineering.

Why “Tokens & Traces”?

Modern technical work increasingly sits at the intersection of statistical models and deterministic systems:

  • Tokens: Representing the discrete units of natural language processing, transformer context windows, and generative model weights.
  • Traces: Representing stack traces, execution flows, memory alignments, network telemetry, and side-channel analysis.

Here, I publish deep dives, empirical benchmarks, and code walkthroughs.


What to Expect

Articles on this site fall into three core categories:

  1. Machine Learning Mechanics: Deconstructing attention routing, transformer interpretability, and autograd backpropagation engines.
  2. Computer Security: Exploring adversarial prompt injections, context window poisoning, and threat models for deployed models.
  3. Systems & Performance: Building lightweight runtimes in C++ and Python, memory alignment optimization, and high-throughput daemons.

Code & Mathematical Formulations

Technical posts may include code snippets and explicit mathematical derivations:

def scalar_autograd_example():
    """Example autograd forward pass."""
    x = 2.0
    w = 3.0
    b = 1.0
    out = x * w + b
    return out

$$\mathcal{L}(\theta) = \frac{1}{N} \sum_{i=1}^N \ell(f(x_i; \theta), y_i)$$
