Automation should be at the heart of every software company. If have to configure something manually: script it. Save the script. Use the script. Automate. Anything. Automation. First. Period.
Chris Vahl (Cloud Engineer) and me did a talk on Full Stack Live #2 (Orange Talent: At Wehkamp we did a very successful influencer campaign, but it didn’t go well for our website. In this session we discuss what happened and how we mitigated our problems. We also show how we want to move forward using Kubernetes, Karpenter and Keda, to create a platform that scales better. This session is in Dutch.
Let’s use a small snippet to convert any article to Markdown. This might come in handy if you want to repost your articles to blogs that support Markdown like DEV.
This week we had to exfil some data out of a bucket with 5M+ of keys. After doing some calculations and testing with a Bash script that used AWS cli, we decided to go a more performant route and use s3p. They claim to be 5-50 times faster than AWS cli 😊.
Let’s face it, using positional arguments like $1 and $2 for your arguments is not very descriptive and not very flexible. There is a better way to supply arguments: with this simple trick you’ll get named arguments in your-script, which is way better 🤓.
At Wehkamp, we use Google Analytics extensively to measure how many users are active. It is hard to correlate active users with your other statistics that “live” in Prometheus. In this blog I’ll show how you can use the Google Real Time API to produce statistics for active users, page views and screen views.
At Wehkamp we use Redis a lot. It is fast, available and implemented as a managed AWS service called ElastiCache. Sometimes we need to extract data from Redis, and usually I use the redis-cli to interact from the command-line. But what if you need to get the values of 400k+ keys? What would you do? Is there an effective way to query multiple key/values from Redis?
This week I needed to query an ElastiCache instance on AWS – which is Amazons version of Redis. I could not find a decent free client to query this remote dictionary, so I ended up using redis-cli on Ubuntu. Turns out: Redis is a wonderful and powerful system to work with.
I have no idea how I came to this point, but the yellow colors in my terminal (both cmd and PowerShell) are not bright yellow anymore. So I want to reset my colors back to the old values! Turns out that getting them back is not as straightforward as I had hoped…
Today I had some data coming into our event driven landscape, so I needed to know when my data was processed. As it constituted the processing of 400.000+ records (and I had more things to do), I needed a small script that kept an eye on my JSON API endpoint to see if the values are changed.
I imagine your first thought is: why? Well, at Wehkamp we do a lot of cross platform development, but sometimes we end up with shell scripts that do stuff with Docker and Python. Usually that’s not a problem for Mac, but for Windows it’s a different thing. I have a MacBook Pro, but I’m a .NET developer, that’s why I prefer Windows, so I run Bootcamp. This article will show how to do Python development in the Windows Subsystem for Linux (WSL) using Visual Studio Code and Docker.
