The common FastAPI pattern of injecting a database session via Depends() creates a long-lived session that spans the entire request lifecycle. This causes subtle bugs. The pattern def get_db(): db = SessionLocal() try: yield db finally: db.close() @app.get("/users/{user_id}") def get_user(user_id: int, db: Session = Depends(get_db)): return db.query(User).filter(User.id == user_id).first() The…
Python 3.11 introduced asyncio.Runner which allows async test support without pytest-asyncio.

With the explosion of agent frameworks we’re seeing different approaches to defining agent “tools” in python. The two immediately obvious approaches are using the docstring or using a pydantic model to define the tool arguments. Opinions wanted : I don’t have an agent framework to shill, nor do I really have a strong opinion about either right now. I also reserve the right to change the pros and…

Add it to your conftest.py and async tests will run in an an asyncio.Runner import asyncio import inspect import logging from contextlib import contextmanager from…

In an attempt to match a restaurant quality Neopoliatan pizza, I've been experimenting with different pizza dough recipes and toppings. Most the experiments below have been made using an Ooni Koda 12" and use Shipton Mill's 00. Jan 23 2021 For 4 pizzas... using the same ratios as last time (before I started documenting). Experimenting with timings from https://github.com/hendricius/pizza-dough .…
Inspired by Joshua Weissman's 5 Ingredient Homemade Flour Tortillas and a bunch of reddit comments about making the perfect mission style flour tortilla. You can just mix all the ingredients together, then roll out but I find letting the dough autolyse for 30mins before adding the oil and salt makes the tortilla's extra soft and tasty. Ingredients 350g plain white flour 190ml warm water 6g salt…

I've enrolled myself in the Duke University course Statistics with R on Coursera. This is a quick note around how I setup R and R-studio on MacOS Sierra and above. Step 1: Install Homebrew and Cask . Homebrew is a package manager for MacOS and Cask allows you to install Apps using the Homebrew CLI. /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"…

I have been writing web services in Go for approaching 2 years now. The factory pattern is something I have found particularly useful, especially for writing clean, concise, maintainable and testable code. Originally I used it just for the data access layer so I could swap in and out upon MySQL, PostgreSQL, etc without changing the application layer code but it has proved useful in many other…
Day 1 & 2: Dublin - Kilkenny Landing in Dublin was eventful. The wind meant the plane was thrown around like a rag doll with wings all the way down. After surviving the descent and getting our bags, we met up with our friend Bronte, who was on exchange in Glasgow. She was taking a couple of days off before returning to Glasgow for exams. Then it was time for hire car number 2. Our steed for the…
After a relatively short bus ride in from Schiphol Amsterdam we arrived at our first AirBnB. AirBnB lets people put their spare bedroom or granny flat to good use, meet people from around the world and make some money at the same time. I love it because it means you're not in an impersonal hotel or hostel and get to meet the locals! Amsterdam is famous for its skinny houses and steep staircases as…
I love Dresden. It feels like my second home and one of the few places where I feel like a local. Known as the Florence on the Elbe it is a city with a rich and colourful history. It was firebombed at the end of World War 2 and many buildings remained destroyed until the fall of the Berlin Wall and East Germany in 1989. Since then millions of hours and euros have been spent rebuilding the city to…
Following our graduation a couple of weeks ago my better half (Genevieve) and I decided we should do something to mark the occasion. As we both share a love of travel and will only get 4 weeks of annual leave this year we decided to fill our last couple of months of freedom with one big holiday - a last hurrah! Over 52 days we will visit Dresden (via Munich), Amsterdam, Ireland, Toronto, Winnipeg,…
