If you’re trying to use Apache Airflow to copy large objects in S3, you might have encountered issues where S3 complains about you sending an InvalidRequest. We will fix that in this post by writing a custom operator to handle the underlying problem.
Even though I had opted out of performance measurement cookies, I noticed a lot of web requests that look like performance measurement in the AWS console. In this article I investigate what’s being sent and what we can do about it.

There are things whose price doesn’t seem proportionate to their usefulness. Simple things. Common things. One such item, which I bought from a drugstore in Germany a couple of years ago, is a reusable shopping bag. It’s a simple bag, made, I think, out of polyester and comes with a smaller bag to carry it in. I paid maybe 2€ for it. Since then I’ve been using it 3-4 times per week to carry around all kinds of stuff. When I still lived in Germany I frequently went out with a backpack, so I only needed to use the reusable bag if I was buying lots of groceries, but since I emigrated to Bulgaria, that situation has changed. ...
I’m currently diving a bit deeper into Apache Airflow and want to further my understanding of the system. I chose to install it locally on my Mac because a managed service like Managed Workflows for Apache Airflow (MWAA) on AWS limits how much I can tinker with the system. For anything remotely production-related, I’d still go with the managed service. I used the Airflow: Getting Started documentation to do exactly that, getting started. Now you might wonder: why write this post then? I found that I had some trouble getting things to work on MacOS specifically, so this is for everyone out there who’s trying to do this on a Mac. ...
A few years I got a Casio F-91W watch (Wikipedia). I was looking for something that can double as a watch and stopwatch while explicitly not being a smartwatch. I wanted something light and sturdy. I was also looking for something inexpensive as I wasn’t sure if I was a watch person since I hadn’t worn any kind of jewelry in the broadest possible sense of that word for many years. I was primarily interested in getting a stopwatch to use while running because I don’t like carrying my phone, which is my usual timepiece. ...
Using Industry Quest: Manufacturing and Auto you can learn about building IoT and factory management solutions in AWS. It’s a game that teaches you about real time monitoring, predictive maintenance, machine learning and data analytics. This blog gives an introduction to the game and covers my thoughts about its usefulness.
Switching the Identity Provider in the IAM Identity Center while keeping all permissions intact and minimizing disruptions can be a daunting task. In this post I’m explaining how we solved this for one of our customers.
I’ve been an Amazon Customer for more than half of my life and recently it became possible to download the data that Amazon stores about me (thank you, EU!). I downloaded my data and built a Dash app to analyze what I spend my money on.
After almost 7 years my headphones are having trouble holding a full charge and start screaming at me to recharge after about 30 minutes. In this post I walk you through changing the battery in Sennheiser PXC 550 headphones.
