Make figurines with AI for 3D printing

Fri, 22 May 2026 10:00:00 -0400

Good 2D toy art beats a fancy image-to-3D model. This post walks the steps in order, links a slide deck, a ComfyUI workflow, and how I sketch the flow with uml-mcp.

Exploring movie similarities with vector search algorithms

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

I taught a thread on “find movies like this” that kept growing: embeddings in PostgreSQL, the same idea in Qdrant with two different vector meanings, then retrieval + a local LLM grounded on the same rows. This page is the story; notebooks and animations live in AlgoETS/SimilityVectorEmbedding. Version française.

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

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

I took part in QcES (Spring 2024 cohort) while working through lean discovery: business model canvas, customer interviews, short pitches, and everything in between. This post is my own recap—not an official program document. Full article in French if you prefer.

Python library for MarketWatch virtual trading

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

I wanted to automate chores in MarketWatch’s virtual stock game (paper trading, not a real broker). marketwatch on PyPI is the small client I shipped — watchlists, game state, portfolio, orders, leaderboard. Version française.

git clone https://github.com/antoinebou12/ESP32-7SEG.git
cd ESP32-7SEG

Open the project in PlatformIO (or Arduino IDE with equivalent libraries), build, and flash the ESP32. After boot, check the serial monitor for the device IP address, then open it in a browser on the same network to use the web UI.

GraphQuon 2025 — University of Toronto

Sat, 15 Nov 2025 10:00:00 -0500

GraphQuon is the annual Quebec–Ontario pre-SIGGRAPH workshop. The 2025 edition ran 15–16 November 2025 at the University of Toronto (series page). I presented there with Sheldon Andrews (ÉTS): Where to Wear? — how frictional contact leaves a readable history on surfaces, and how we can turn that into graphics and engineering feedback.

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

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

Blender add-ons that need NumPy, meshio, or requests hit the same wall: Blender ships its own Python, so system pip does nothing useful. I wrote a small installer that targets Blender’s sys.executable, drops wheels under scripts/modules, and runs in a background thread so the UI stays responsive (Blender 4.2+, Windows). Version française.

GraphQuon 2024 — ÉTS (Montréal)

Sat, 09 Nov 2024 09:00:00 -0500

GraphQuon (formerly MOTOGRAPH) is the annual Quebec–Ontario pre-SIGGRAPH workshop for East-Canadian computer graphics labs. The 2024 edition ran 9–10 November 2024 at École de technologie supérieure (ÉTS) in Montréal. I helped build and host the conference website at graphquon.github.io so schedules, registration, and past editions stayed in one place. Version française.

Multiple Technical Indicators Backtesting on Multiple Tickers using Python

Thu, 30 May 2024 15:00:00 -0400

Same BatchBacktesting engine as the earlier indicator experiment, but emphasized at portfolio scale: many tickers, two strategies, equities plus crypto, aggregate winners and losers. Version française.

Economics of LEGO Sets with Data Science

Thu, 30 May 2024 12:00:00 -0400

I collect LEGO and write Python — so I merged Rebrickable exports with a BrickEconomy scraper to see how sets, colors, and themes evolved, and whether a simple model could explain prices on classics like 001-1. This page is the story with charts; full notebooks live in AlgoETS/LegosTracker. Version française.

Experimenting with technical indicators using Python and backtesting

Tue, 14 May 2024 20:00:00 -0400

I batch-ran EMA and MACD strategies across many tickers with BatchBacktesting — FMP for equities, Binance for crypto. This post explains what the runner does, how to read outrageous leaderboard rows, and why that is not a live trading system. Version française.

Making Caddy, AWS EC2, CloudWatch, Step Functions, and Lambda Work Together

Tue, 14 May 2024 18:00:00 -0400

I already ran Caddy at home for Home Assistant. This article is the AWS edge version: EC2 (often t4g.nano), automatic HTTPS, JSON access logs in CloudWatch, a nightly Python shipper, and Lambda + Step Functions for cheap observability — not a SaaS dashboard bill. Version française.

A Journey to AWS Certified Cloud Practitioner

Tue, 14 May 2024 16:00:00 -0400

I passed the AWS Certified Cloud Practitioner (CLF-C02) after about two weeks (~60 hours) of focused study — not because the exam is trivial, but because mixing video, labs, and silly gamified prep kept me moving. This post is the resource stack that worked for me (Udemy, Skill Builder, Cloud Quest, Escape Room) plus Pearson VUE practicalities: extra time if English is not your first language, online proctoring, Credly badge. Version française.

Predicting Stock Prices with Monte Carlo Simulations

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

Trading is about ranges, not one magic price. I used forward Monte Carlo on Apple daily closes: estimate log-return drift and volatility before 2023, simulate many paths, then check whether 2023 hold-out prices fell inside a 5th–95th percentile band. Version française.

Kinectron + p5.js — sketch controls and GIF export

Fri, 15 Mar 2024 10:00:00 -0400

For a creative-coding class I needed Kinectron skeleton data inside p5.js, with simple play / stop controls and a way to export a short GIF for demos. Notes below are the skeleton I used (Kinect v2 or Azure Kinect DK, Kinectron server running). Version française.

MediaBox homelab — what I run in Docker (and what stayed a bookmark)

Fri, 15 Mar 2024 10:00:00 -0400

I kept a private list of self-hosted apps I wanted to try — mostly so I would stop assigning random ports and forgetting what lived on :8096. That list turned into MediaBoxDockerCompose on GitHub. This post is the short version: what I wired up, how I install on Proxmox when compose is not the right shape, and where the full port map lives so this page does not become a spreadsheet with SEO.

Byzantium’s first workshop — Solidity and an ERC-20 token on Ethereum

Mon, 11 Mar 2024 18:30:00 -0400

On 11 March 2024, Byzantium ran its first Ethereum workshop at ÉTS: a hands-on evening where people who had never touched a chain left with a testnet token they could send to a friend. Khalil Anis Zabat led the session in French; this page is the English recap. Version française has the same story with a bit more room for detail.

Sat, 06 Jan 2024 10:00:00 -0400

Week one of moving my site to Hugo (January 2024): pick a theme, ship something fast, and prove the repo could carry more than a PDF résumé. This post is the log — HBTheme, a data story embed, Substack in parallel, and a reusable iframe shortcode. Version française.

MediaBoxDockerCompose

Mon, 01 Jan 2024 12:00:00 +0000

Repository · MIT License

Compose-first homelab media stack: fetch content (torrents and Usenet), route it through *Arr apps, add subtitles where needed, then serve libraries with Plex or Jellyfin, with request UIs and monitoring. Configuration is meant to live under a shared ROOT tree on disk as in the repo’s docker-compose.yml.

My journey in software engineering

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

I did not start in Kubernetes. I started in browser tabs, game loops, and a makerspace that smelled like hot PLA. This post is the longer version of that path—backend, platform, and DevSecOps are where I landed, but the steps in between matter. Version française.
