Should you be writing a book next?!

At last my book is done and soon coming to an online book store near you. It's been 4 months in the making and I spend a lot of time writing it. I feel relieved that it's done and I'm a little anxious what people will think. I had a lot of fun writing it. Should you be writing a book too?

Building a custom mechanical keyboard - Part 1

I've always been a huge fan of mechanical keyboards. Personally I use the daskeyboard mechanical keyboard. It's a clicky, loud typing beast. Great for writing books and blogposts and occasional programming when I get to it. But I want something different. I decided to build an Iris custom keyboard.

Machine Learning

It's easier than ever to add machine learning to your C# program. Use ML.NET!

In the past machine learning was something exclusively for the pythonistas or data scientists that knew how to use Python or R and had studied statistics. Not anymore, it has become a lot easier for developers to use machine learning. This also goes for .NET developers.

Learn how to quickly generate REST clients from Open API Specification files

Often when you work with REST endpoints the makers of these endpoints expose swagger (Open API Specification) files. Many developers however still handcode their clients. Not only is this bad. Here's a better way to generate your clients.

3D printing

We bought our first 3D Printer and had a massive learning experience!

A few weeks ago my wife asked me for a 3D printer. She wanted to make art and small things around the house. Two weeks ago we spend a whole evening researching and comparing 3D printers and design software. It turns out to be quite an adventure and we learned a lot along the way.

3 Must-have tools if you're serious about machine learning

When working on machine learning problems I find that productivity is sometimes somewhat low, because I have to spend a lot of time working on tedious bits that probably can be automated away. Over time I have found quite a few tools that help me get better results faster. Here's three of them.

What I've learned getting my colleagues up to speed with AI

How do you start with AI when you're a developer and have no idea where to begin? Organize a workshop for your colleagues and challenge them to start exploring machine learning. I certainly learned a ton while organizing the AI learning experience. It was a lot of fun.

I'm building my own deep learning framework and that's crazy

I've embarked on my hardest and most fun adventure ever. I'm going to implement my own deep learning framework. I know most people will call me crazy. But I think this is a challenge that was long coming and I finally got around to it. Wonder why? Read on.

Chatbots

Learn how to build a bot with the new Microsoft Bot Builder Java SDK

Bot builder from Microsoft has been around for a couple of years now. During Microsoft Build 2018 a preview of version 4.0 was launched with support for more languages. Previously you could only build a bot in C# or Node. Now you can build one in Java too. Here's how.

Machine Learning

Learn how automatically tag images with the Computer Vision API

When you're not into building your own machine learning models or neural networks, but still want to do something with AI to recognize images, then Microsoft has you covered with the Computer Vision API as part of their Cognitive Services. Wonder how to use it? Learn it here.

Learn how to visualize your CNTK based neural network

When you're building complex neural networks you often want to visualize them. Visualization offers a great way to debug things like performance bottlenecks, because parts of your network get duplicated by CNTK. Luckely, it is quite easy to visualize a neural network in CNTK. Here's how.

Here's why Microsoft Cognitive Toolkit is the coolest deep learning framework around

Microsoft cognitive toolkit supports loading and saving models in ONNX format, which enables you as a developer to run your trained network on Java and C# with much better overall performance than you can get with Python.

Adventures in AI part 3: How do I know my ML model is any good?

You can train any model you like for your AI solution, but it is only as good as the data you feed it. But how do you measure the performance of a machine learning model? In this third part of the series on AI models I will show you how.

How to quickly build a REST API in Django

Vacation time, an excellent time to learn something new, so I figured, why not build a recipe bot that recommends recipes? For that I needed a way to store recipes that the bot could retrieve. And I figured, why not try to build that in Python with Django?
