Compiler pipeline, language genealogy, and why grammars matter

Mon, 13 Apr 2026 15:40:00 -0400

These figures come from a programming languages / compiler design textbook I was reading for a course. I kept the photos as a single reference page: how compilation is staged, how today’s languages relate historically, and where syntax stops being enough — you need precedence rules, disambiguation for things like else, and attributes for semantics such as types.

Compiler pipeline

The usual story: source program → lexical analyzer (tokens) → syntax analyzer (parse trees) → intermediate code (with semantic analysis) → optional optimization → code generator → machine code on a computer, plus input data and results. A symbol table sits beside the front phases and feeds the back end.

Exploring movie similarities with vector search algorithms

Mon, 13 Apr 2026 12:00:00 -0400

This is a single walkthrough of a movie similarity thread: Part 1 stores embeddings in PostgreSQL + pgvector and runs nearest-neighbor search in SQL; Part 2 uses Qdrant with MovieLens (dense text vectors for semantic search and sparse rating vectors for collaborative-style recommendations); Part 3 turns the same pgvector-backed catalog into the retrieval layer for a small RAG pipeline with LangChain and Ollama. Below are short GIFs from that work (movie-similarities-1.gif … 3.gif in this page bundle).

Dimension — a Rust math stack around mathlib

Mon, 13 Apr 2026 10:00:00 -0400

What it is

Dimension is a monorepo I use to experiment with numerical code in Rust. The piece that holds most of the public API is mathlib: a linear-algebra-focused crate with dense and sparse matrices, vectors, standard decompositions (SVD, Cholesky, LU, PCA), solvers, and a large set of building blocks for graphics-style math (3D types, quaternions, dual quaternions, cameras, easing, curves).

The repo also pulls in related crates for simulation and tooling—kinematics, physics, geometry, rendering demos, neural bits, and a small site that packages some of the WASM demos—so mathlib stays the shared numeric core while other folders explore how that core feels in real programs.

From BMC to pitch — QcES journey notes (Spring 2024)

Mon, 13 Apr 2026 10:00:00 -0400

Full article in French — same slug; you can also switch to FR in the header.

At a glance

The Business Model Canvas (BMC) describes how an organization creates, delivers, and captures value; it answers three questions: desirability, feasibility, and viability.
You usually start with customer segments and value proposition, then iterate—the model evolves with the market.
Segmentation makes the market concrete (B2B vs B2C, crisp criteria) instead of vague labels (“doctors”, “parents”).
Interviews are for discovery: the goal is to learn, not to sell; connect, don’t convince—and stay attached to the problem, not your first idea of the solution.
Structured feedback (strengths + one growth angle) and a short spoken pitch (no slides) clarify the idea early.
A product roadmap is a strategic view over time, not a detailed project plan; it aligns vision, audience, horizon, metrics, and resources.
PoC, prototype, and MVP play different roles: technology check, user interaction learning, then a first market version you can stress-test with real users or buyers.
Market and value proposition: account for external forces (macro, industry, trends) and express value as offer + customer benefit.
A solid pitch often follows Hook → Believe → Join: lead with the problem, show credibility and differentiation, then make a specific ask.

This is a personal write-up based on QcES materials (Spring 2024 cohort) and facilitators; it is not an official program document.

Python library for MarketWatch virtual trading

Mon, 13 Apr 2026 10:00:00 -0400

I published marketwatch on PyPI: a small Python client for the MarketWatch virtual stock game (paper trading), not live brokerage access. If you want to script watchlists, pull game or portfolio data, or experiment with automation against the game, it wraps the flows in a straightforward API.

What it can do

Create and manage watchlists
Read game details and settings
Inspect portfolio, positions, and pending orders
Buy and sell (in-game)
Fetch the leaderboard for a game

Useful if you are exploring automated strategies or small bots inside the game’s rules—see the docs for method names and return shapes.

Software lifecycle notes — GOALS, waterfall, and verification vs validation

Mon, 13 Apr 2026 08:00:00 -0400

These pages are from a software engineering textbook I used in coursework. I grouped the figures here as a single reference: goal-oriented planning, how the waterfall model sequences activities (with verification and validation paired to each phase), an incremental variant, the textbook’s list of life-cycle subgoals, a reminder that method advice depends on context, and a short ethics passage about impact on people.

GOALS approach (Figure 3-1)

The GOALS flowchart is a top-down pattern: set overall life-cycle goals (functions, constraints, schedule, usability, maintainability), analyze the problem and sketch solution structure, separate concerns into subgoals, develop solutions for each subgoal in parallel where possible, then validate those solutions against the other goals and iterate until the decision “all goals satisfied?” is yes.

A Method to Install Python Packages for Add-ons & Plugins in Blender (Windows, Blender 4.2+)

Sat, 08 Feb 2025 12:00:00 -0400

Introduction

Blender is a powerhouse for 3D creation, offering a Python API that allows users to extend its functionality with scripts, add-ons, and plugins. However, one challenge developers face is installing external Python packages within Blender’s isolated Python environment.

Unlike system-wide Python installations, Blender bundles its own Python interpreter, making standard package installations tricky. This article presents a more general and robust method to install Python dependencies for Blender add-ons and plugins — ensuring a smooth workflow across different versions.

ChatGPT plugin with FastAPI — implementation outline

Sat, 01 Jun 2024 10:00:00 -0400

OpenAI-style plugins expose an HTTP API described by an OpenAPI document so ChatGPT can call your tools safely. FastAPI generates OpenAPI for you, which fits this model well.

1. Define the API in FastAPI

Routes return JSON with stable shapes (no ambiguous free text where structure matters).
Add summaries and descriptions on paths and fields — they help the model choose the right tool.

2. Publish `openapi.json`

FastAPI serves /openapi.json by default; the plugin manifest points at this URL (or a static copy you version).
Keep schemas tight: enums, required fields, and examples reduce bad calls.

3. Plugin manifest

Host ai-plugin.json (or the format required by the current OpenAI developer docs) over HTTPS.
Manifest references your API base URL and OpenAPI location.

4. Auth

Prefer OAuth or API keys as documented for your integration; never commit secrets.
Validate tokens inside FastAPI dependencies or middleware.

5. Deploy

HTTPS endpoint reachable from OpenAI’s servers.
Logging and idempotency for side-effecting routes.

6. Test manually

Call routes with curl or HTTPie using the same payloads the model will send.
Iterate on descriptions and constraints before exposing wide traffic.

Details change with OpenAI’s platform updates — always follow the latest plugin / tools / actions documentation when wiring production apps.

Predicting Stock Prices with Monte Carlo Simulations

Tue, 14 May 2024 09:00:00 -0400

Introduction

In finance, decisions are rarely about a single “forecast” price: they are about ranges, tail risk, and how wrong simple models can be. This article walks through a Monte Carlo path simulation in Python: we estimate drift and volatility from historical closes, simulate many future price paths (a geometric Brownian–style discrete step), and summarize the result as a distribution—the right object for risk-style questions (bands, percentiles, coverage against a hold-out period).

Responsive step progress bar (jQuery + CSS)

Mon, 12 Feb 2024 10:00:00 -0400

This code creates a responsive progress bar with four steps. It uses jQuery for dynamic text changes and CSS for styling. Here’s a breakdown of its functionality:

HTML Structure

The progress bar is wrapped inside a div with the class progressbar_container.
An unordered list (ul) with the class progressbar represents the progress bar.
Each step in the progress bar is an li element with the class progressbar_node.
The current step is highlighted by adding the class current_node.

CSS Styling

The .progressbar_container is styled to position the progress bar, manage its size, and center it.
Each .progressbar_node represents a step in the progress bar.
The :before pseudo-element of .progressbar_node creates circular step indicators with numbers.
The :after pseudo-element creates connecting lines between the steps.
The current and completed steps are highlighted with a darker color and a solid border.

JavaScript Functionality

On document ready ($(document).ready), the previous steps to the current step are marked as completed using the class activated_node.
A resize event listener ($(window).resize) changes the text of the first step based on the window’s width. It toggles between “PASSENGER” and “PASSENGER DETAILS”.

Notes

Ensure you have included the jQuery library to use the jQuery syntax.
The resizing functionality helps maintain responsiveness, providing a better experience on different screen sizes.

Example Usage

To use this progress bar, include the provided HTML in your document. Ensure your CSS is properly linked, and the jQuery library is included for the JavaScript to work correctly.

My journey in software engineering

Sat, 30 Dec 2023 10:00:00 -0400

This site’s bio sums up the slice of the field I care about most: backend, platform, and DevSecOps. This post is a longer look at how I think about that journey — not a timeline of jobs, but the ideas that kept showing up once I stopped treating “shipping features” as the only scoreboard.

From features to systems

Early on, progress often feels linear: tickets closed, endpoints added, screens shipped. That work matters. Over time, though, the interesting problems sit one level up: how services talk to each other, how failures propagate, how a change in one team’s repo affects everyone else on Monday morning. Backend engineering stops being “write the handler” and becomes “design something that stays understandable when you’re not in the room.”

Live chat and support platforms compared (3CX, ManyChat, Kommunicate, Chatwoot)

Tue, 06 Sep 2022 10:00:00 -0400

These notes come from comparing options for website live chat, chatbots, and a shared support inbox. The products below are not interchangeable: some are full communications stacks, others are marketing automation, and one is an open-source helpdesk. Pricing, channels, and features change often—treat this as orientation, then confirm on each vendor’s site.

3CX

3CX is primarily UCaaS / PBX (phones, meetings, extensions). Its web live chat and related widgets sit in that same ecosystem, which helps if you already route voice and chat through 3CX and want one vendor for queues and agents.

Renpho scale, Home Assistant, and reverse-engineering the API

Sun, 10 Oct 2021 10:00:00 -0400

Inspiration from Bryan Johnson’s “Blueprint Protocol”

Personal health tracking, for me, started with Bryan Johnson’s “Blueprint Protocol”—a push for self-quantification that matched how I already thought about fitness. I wanted the same granularity for my own body, and a Renpho scale with bio-impedance turned out to be a practical way to get a steady stream of numbers beyond simple weight.

Forking hass-renpho and the Home Assistant ecosystem

I found hass-renpho, a custom integration that pulls Renpho scale data into Home Assistant. The project had gone quiet, and with the original maintainer unavailable I forked it to extend support for more of the metrics the hardware exposes.

DasherControl

Mon, 06 Sep 2021 22:42:23 +0800

DasherControl

Another Interactive Configurable Dashboard with Customisable GridItem with IFrame and Bookmark and other cool features with basic Container Controller for Docker made with Vuejs and Rust (rocket).

Why …

Everything is a web app that can be installed with a docker in a container. I want to manage all my web applications on one dashboard like Sonarr and Jellyfin without opening like 10 tabs in chrome (rip my ram). When using services like Portainer or the Docker CLI, it’s long to set up a reverse proxy with SSL to secure your homelab. So I want to write widgets (Applets) that can do all my tasks that I do on the daily when managing my homelab. Also, I want to make a simple dashboard with widgets (vuejs component) like Windows Vista, but on the web and saved in a database.

Networking evolution — building a home network lab

Mon, 06 Sep 2021 10:00:00 -0400

Introduction

Welcome to a new chapter in my blog where I dive into the intricacies of building a robust home networking system. As a software engineer with a passion for networking protocols and efficient computing, I’ve embarked on a journey to design a system that balances performance, security, and cost-effectiveness. This post will detail my experiences and the technical decisions I made along the way.

Embracing the Challenge of Home Networking

My interest in networking began during my academic years, where I learned about various protocols such as IP, VPN, and IP7. Motivated by the high costs of cloud computing, I set out to build a home-based system. My goal was to use older computers, minimizing expenses on hardware and online services, while still achieving a high degree of functionality and efficiency.

Date range picker web component (jQuery + plugin)

Fri, 05 Feb 2016 10:00:00 -0400

This walkthrough is from the jQuery-and-Moment era: you wrap two text inputs in a custom element <daterangepicker-two-input>, register it with customElements.define, and hand the container off to the Date Range Picker plugin. Newer stacks usually reach for native <input type="date">, flatpickr, or framework date components — but plenty of dashboards shipped in the mid-2010s (and many still in maintenance) look exactly like this.

Tutorial: Creating a Custom Date Range Picker Element

Introduction

You end up with a small reusable tag that opens the familiar range calendar UI (check-in / check-out style) while keeping the markup consistent across pages.

Custom countdown timer (HTML, CSS, JavaScript)

Mon, 01 Feb 2016 10:00:00 -0400

This is a straight DOM-and-setInterval countdown: minutes in, tick down, start and reset, and a short audio clip when it hits zero — the sort of thing that showed up in every “learn JavaScript” blog around 2016 before frameworks swallowed the front page.

Tutorial: Building a Custom Countdown Timer

Step 1: Setting Up the HTML Structure

First, we’ll create the basic structure of the timer. This includes input fields for minutes, a display for the countdown, and buttons to start and reset the timer.

Three.js 3D wave animation (CodePen tutorial)

Thu, 07 Jan 2016 12:00:00 -0400

CodePen demo

Introduction

This walkthrough builds a 3D wave animation with Three.js: scene, camera, WebGL renderer, a grid of cubes, and a simple undulating motion — the sort of “look, WebGL in the browser” demo that fit right in with 2016 Three.js + CodePen articles. Use the embed above to tweak it live.

Setting Up the Scene

First, let’s set up the basic components of any Three.js scene: the scene itself, a camera, and a WebGL renderer. Add the following code to initialize these components:

HTML5 Canvas blackboard (CodePen tutorial)

Thu, 07 Jan 2016 11:00:00 -0400

CodePen demo

Introduction

This tutorial walks through a simple interactive blackboard with HTML5 Canvas and plain JavaScript: drawing, pulling in images via the File API, and clearing the board. It matches the kind of step-by-step CodePen write-up that was everywhere around 2016. Use the embed above to see the finished behavior.

Setting Up the Canvas

First, we need to set up the HTML5 canvas element. This is where all the drawing will take place.

Draggable, sortable image bubbles (Messenger-style)

Thu, 07 Jan 2016 10:00:00 -0400

Tutorial: Creating Draggable and Sortable Images with jQuery

Introduction

This walkthrough uses jQuery and jQuery UI to build circular “bubble” avatars you can drag and reorder — the same ingredients that showed up in countless demos when Messenger-style circles and sortable lists were everywhere (roughly the ES5 + jQuery era, ~2016). Handy for legacy pages or if you want the recipe in one place.

Prerequisites

Basic knowledge of HTML, CSS, and JavaScript
jQuery and jQuery UI library

HTML Structure

We start by setting up our HTML structure with two unordered lists (ul) and list items (li) containing images.
