[P] Trained a small BERT on 276K Kubernetes YAMLs using tree positional encoding instead of sequential
I trained a BERT-style transformer on 276K Kubernetes YAML files, replacing standard positional encoding with learned tree coordinates (depth, sibling index, node type). The model uses hybrid bigram/trigram prediction targets to learn both universal structure and kind-specific patterns — 93/93 capability tests passing. Interesting findings: learned depth embeddings are nearly orthogonal (categorical, not smooth like sine/cosine), and 28/48 attention heads specialize on same-depth attention (up to 14.5x bias).

Rusty Flying Robots: Learning a Full Robotics Stack with Real-Time Operation on an STM32 Microcontroller in a 9 ECTS MS Course
arXiv:2604.00032v1 Announce Type: cross Abstract: We describe a novel masters-level projects class that teaches robotics along the traditional robotics pipeline (dynamics, state estimation, controls, planning). One key motivational part is that students have to directly apply the algorithms they learn on a highly constrained compute platform, effectively making a robot fly. We teach nonlinear algorithms as deployed in state-of-the-art flight stacks such as PX4. Didactically, we rely on two core concepts: 1) avoidance of provided black-box software infrastructure, and 2) usage of the safe and efficient programming language Rust that is used on the PC (for simulation) and an STM32 microcontroller (for robot deployment). We discuss our methodology and the student feedback over two years with
I Built a Privacy-First Developer Toolbox That Runs 100% in Your Browser
Every developer has a handful of tools they reach for daily: a JSON formatter, a Base64 decoder, a timestamp converter. I got tired of pasting sensitive data into random websites that "promise" not to store it, so I built my own. DevTools is a collection of 8 developer tools that run entirely client-side. No server uploads. No data collection. Everything happens in your browser tab. What's Inside JSON Formatter - Format, validate, and minify JSON with auto-detection of nested escaped strings Base64 Converter - Encode and decode Base64 with full UTF-8 and emoji support URL Encoder - Percent-encode/decode URLs with international character support JWT Decoder - Decode JSON Web Tokens locally without ever sending your tokens to a server Timestamp Converter - Convert between Unix timestamps and
