Microsoft Face API with a local container
A few days ago, I obtained access to the Face container. It provides access to the Face API via a container you can run where you want: on your pc, at the network edge or in your datacenter. You should allocate 6 GB or RAM and 2 cores for the container to run well. Note…
Building a real-time messaging server in Go
Often, I need a simple real-time server and web interface that shows real-time events. Although there are many options available like socket.io for Node.js or services like Azure SignalR and PubNub, I decided to create a real-time server in Go with a simple web front-end: For a real-time server in Go, there are several options.…
Infrastructure as Code: exploring Pulumi
Image: from the Pulumi website In my Twitter feed, I often come across Pulumi so I decided to try it out. Pulumi is an Infrastructure as Code solution that allows you to use familiar development languages such as JavaScript, Python and Go. The idea is that you define your infrastructure in the language that you…
Azure API Management Consumption Tier
In the previous post, I talked about a personal application I use to deploy Azure resources to my lab subscription. The architecture is pretty straightforward: After obtaining an id token from Azure Active directory (v1 endpoint), API calls go to API Management with the token in the authorization HTTP header. API Management is available in…
Simple Azure AD Authentication in a single page application (SPA)
Adding Azure AD integration to a website is often confusing if you are just getting started. Let’s face it, not everybody has the opportunity to dig deep into such topics. For https://deploy.baeke.info, I wanted to enable Azure AD authentication so that only a select group of users in our AD tenant can call the back-end…
Azure Front Door in front of a static website
In the previous post, I wrote about hosting a simple static website on an Azure Storage Account. To enable a custom URL such as https://geertbaeke.wordpress.com, you can add Azure CDN. If you use the Verizon Premium tier, you can configure rules such as a http to https redirect rule. This is similar to hosting static…
Static site hosting on Azure Storage with a custom domain and TLS
A while ago, I blogged about webhookd. It is an application, written in Go, that can easily convert a folder structure with shell scripts into webhooks. With the help of CertMagic, I modified the application to support Let’s Encrypt certificates. The application is hosted on an Azure Linux VM that uses a managed identity to…
Running a GoCV application in a container
In earlier posts (like here and here) I mentioned GoCV. GoCV allows you to use the popular OpenCV library from your Go programs. To avoid installing OpenCV and having to compile it from source, a container that runs your GoCV app can be beneficial. This post provides information about doing just that. The following GitHub…
Using the Microsoft Face API to detect emotions in photos and video
⚠️ IMPORTANT: the Face API container was retired early 2021. The container image is not available anymore. In a previous post, I blogged about detecting emotions with the ONNX FER+ model. As an alternative, you can use cloud models hosted by major cloud providers such as Microsoft, Amazon and Google. Besides those, there are many…
Detecting emotions with FER+
In an earlier post, I discussed classifying images with the ResNet50v2 model. Azure Machine Learning Service was used to create a container image that used the ONNX ResNet50v2 model and the ONNX Runtime for scoring. Continuing on that theme, I created a container image that uses the ONNX FER+ model that can detect emotions in…
