AWS Lambda Size: PIL+TF+Keras+Numpy?
At Wehkamp we’ve been using machine learning for a while now. We’re training models in Databricks (Spark) and Keras. This produces a Keras file that we use to make the actual predictions. Training is one thing, but getting them to production is quite another!
The main problem we’ve faced was that it was too big to actually fit into a lambda. This blogs shows how we’ve dealt with that problem.
Fixing “white” screen Windows 10 start search
I’ve been having some problems with the search feature of Windows 10. It suddenly stopped working. I don’t exactly know when or why, but it did not come back by turning the computer on and off again. Reinstalling Cortana worked for me.
Finetuning screen brightness with PowerShell
When I work in a low-light environment I like to have fine-grained control over the brightness of my monitor. When I change the brightness using the special function keys on my keyboard, it changes in steps of 10%! That’s a lot. PowerShell to the rescue!
Generate XML with attributes using PowerShell
Today I discovered that generating XML with PowerShell isn’t as straight forward as I had hoped. I started off with a CSV that I had to convert to XML. Fortunately PowerShell is very good when it comes to CSV. It was the parsing of the object to XML-attributes that proved the most challenging part.
Building an updatable Slack message
Slack is fully awesome. At Wehkamp we use it for our internal communication and as a tool for our DevOps. The Slack API allows us to build even more advanced integrations. In this blog I’ll explore how to use the API to create powerful progress indicators by updating a Slack message.
Jump-starting Slack bot projects: bot-zero
To give teams a jump start we’ve created the bot-zero open source project. It solves some setup and development problems. In this blog I’ll show how to get up and running in minutes and I’ll explain some of the choices we’ve made.
Cleaning up the default Hubot Slack installation
If you set up a new Hubot using the Slack Developer Kit for Hubot you’ll get an awesome bot, but with a lot of useless stuff in it. In this blog I’ll outline all the things that can be safely cleaned up. The scripts can run on both Powershell (Windows) and Bash (Linux/Mac).
Setup Jenkins (Blue Ocean) using Docker on Synology NAS
Using Docker on a Synology NAS has become really easy. It’s a bit harder to install Jenkins in a container and let it use the Docker installation it’s part of. But we are living in exciting times: bringing a fully functioning CI/CD-pipeline to your home automation has never been easier!
