Connect to Jira with a Private Key (OAuth) using .NET
We have a .NET service that needs to connect with Jira to create, update and read issues. It would be easy if we could use a username & password for authentication, but for this integration we need to implement a Private Key. All requests have to be signed with OAuth. Here’s what we came up with.
Convert JsFiddle to SVG using Node.js
I love SVG, but sometimes they are hard to create, especially when you need to visualize diagrams. HTML is way easier to program. So why not combine them? Can we use HTML to generate an SVG? And can we use JsFiddle to generate that HTML?
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.
Building a high performing last viewed list using Redis
We live in a day and age in which we can choose a data-store that matches the characteristics of our apps and (micro) services. Lately we’ve been looking into Redis as a high performing store for last viewed items. In this blog I’ll look show how to create a POC with the redis-cli and then implement it using .NET Core. We’ll be using the sorted set structure.
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.
Fizz? Buzz? FizzBuzz? Let’s discuss.
What’s the buzz all about? Well, originally it started out as a small children’s game, but now and again I see it being used to detect weak developers in job interviews (I think there are better ways to do this). The assignment has a view nice properties. In this blog I would like to look at some implementations and discuss the pro’s and con’s of each implementation.
Dictionary-style settings as IOptions
I love how we can use appsettings.json files to configure applications in the .NET Core platform. The JSON-format feels a lot less bloated than the old XML appSettings config I used to work with. In this blog I’ll explore how to load a dictionary-style settings class as an IOption. This can be very useful when working with dependency injection.
Setup multiple setting-files with a .NET Console Application
In ASP.NET Core we are used to have multiple appsettings.json files with settings that differ per environment. I want to do the same in a Console Application. This makes debugging the application easier.
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!
