urllib3 is a HTTP client written in Python. We just got 7 billions downloads, 1 million GitHub repositories depend on us, and popular libraries like requests and boto3 use us for performing secure HTTP requests.
We’re currently working on a v2 version that is more modern and secure. It …

urllib3 is a HTTP client written in Python. We get millions of downloads every day, 500k GitHub repositories depend on us, and popular libraries like requests and boto3 use us for performing secure HTTP requests. In short, urllib3 is Python’s most depended-on HTTP client library.
We’re currently working …

I spent the last five days working full-time on urllib3, currently the most downloaded Python package, and a dependency of requests. I can’t believe I’m writing this sentence! But it’s true. A dream come true. This was made possible thanks to:

Python 3. Since Python 3.5, we can use the async and await
keywords:
async def get(self):
await self.wait_for_token()
return self.client.get()
But Python 3.5 also brought support for asynchronous context managers

Since I've began to program, I've heard everywhere that synchronous, sequential programming is a way of the past. In a manycore future, we will need to write programs that execute in parallel. But aside from embarassingly parallel programs, this has always been considered to be too difficult to be worth …

Je travaille à distance depuis La Réunion. La première condition pour du télétravail réussi, c'est d'avoir une bonne connexion Internet. C'est parfaitement possible à La Réunion, mais comment faire quand ça ne va pas ? Il faut savoir où est un problème pour pouvoir le corriger. En arrivant ici, j'aurais aimé …
