I'm not feeling the async pressure
I'm not feeling the async pressure written on Wednesday, January 1, 2020 Async is all the rage. Async Python, async Rust, go, node, .NET, pick your favorite ecosystem and it will have some async going. How good this async business works depends quite a lot on the ecosystem and the runtime of the language but overall it has some nice benefits. It makes one thing really simple: to await an operation
Be Careful About What You Dislike
Be Careful About What You Dislike written on Saturday, November 5, 2016 The last few months I keep making the same observation over and over again in various different contexts: that whenever you are confronted with a very strong opinion about a topic, reasonable discussions about the topic often involve arguments that have long become outdated or are no longer strictly relevant to the conversatio
I don't understand Python's Asyncio
I don't understand Python's Asyncio written on Sunday, October 30, 2016 Recently I started looking into Python's new asyncio module a bit more. The reason for this is that I needed to do something that works better with evented IO and I figured I might give the new hot thing in the Python world a try. Primarily what I learned from this exercise is that I it's a much more complex system than I expe
Rust and Rest
Rust and Rest written on Sunday, July 10, 2016 A few months back I decided to write a command line client for Sentry because manually invoking the Sentry API for some common tasks (such as dsym or sourcemap management is just no fun). Given the choice of languages available I went with Rust. The reason for this is that I want people to be able to download a single executable that links everything
The Python I Would Like To See
The Python I Would Like To See written on Saturday, August 16, 2014 It's no secret that I'm not a fan of Python 3 or where the language is currently going. This has led to a bunch of emails flying my way over the last few months about questions about what exactly I would prefer Python would do. So I figured I might share some of my thoughts publicly to maybe leave some food for thought for future
Rust for Python Programmers
Rust for Python Programmers written on Wednesday, May 27, 2015 Now that Rust 1.0 is out and quite stable, I thought it might be interesting to write an introduction to Rust for Python programmers. This guide goes over the basics of the language and compares different constructs and how they behave. Rust language wise is a completely different beast compared to Python. Not just because one is a com
Why I Don't Hate Git: Hidden Consistency
Why I Don't Hate Git: Hidden Consistency written on Tuesday, February 17, 2015 Git for me is an interesting topic. I used it initially when git had no UI and cogito was still a thing. I can't say I enjoyed using it much. At the time I did all my development tasks with SVN and the world was good. A little while later I played around with mercurial and instantly fell in love. I held onto mercurial f
The Future of Payments and Open Source Support
The Future of Payments and Open Source Support written on Sunday, November 2, 2014 I kept my mouth shut about Bitcoin on my blog so far, but I do feel like I need to bring it up now because of how many comments and mail I got about a bug report I wrote two weeks ago for removing projects of mine from a bounty website called tip4commit. It feels like you are not allowed to say anything other than "
Revenge of the Types
Revenge of the Types written on Sunday, August 24, 2014 This is part two about "The Python I Would Like To See" and it explores a bit the type system of Python in light of recent discussions. Some of this references the earlier post about slots. Like the earlier post this is a bit of a diving into the CPython interpreter, the Python language with some food for thoughts for future language designer
Everything you did not want to know about Unicode in Python 3
Everything you did not want to know about Unicode in Python 3 written on Monday, May 12, 2014 Readers of this blog on my twitter feed know me as a person that likes to rant about Unicode in Python 3 a lot. This time will be no different. I'm going to tell you more about how painful "doing Unicode right" is and why. "Can you not just shut up Armin?". I spent two weeks fighting with Python 3 again a
Python on Wheels
Python on Wheels written on Monday, January 27, 2014 The python packaging infrastructure has long received criticism from both Python developers as well as system administrators. For a long time even the Python community in itself could not agree on what exactly the tools to use were. We had distutils, setuptools, distribute, distutils2 as basic distribution mechanisms and then virtualenv, buildou
Writing Forwards Compatible Python Code
Writing Forwards Compatible Python Code written on Saturday, January 22, 2011 For web applications the safest bet currently is to stick with Python 2.x even for new projects. For the simple reason that right now we don't have enough supporting libraries for Python 3 yet and porting some of them over is a huge step. But with all the people telling one that it's hard and painful to upgrade to Python
Porting to Python 3 — A Guide
Porting to Python 3 — A Guide written on Thursday, February 11, 2010 The latest Jinja 2 release came with basic support for Python 3. It was surprisingly painless to port the application over but it did require a substantial amount of tweaks and code changes in order to get it running. For everyone else out there who is interested in getting started, I decided to share my experiences: Changing API
