Recognizing printed text on images using Azure Computer Vision API

Microsoft Cognitive Services offers us computer vision services to describe images and to detect printed or handwritten text. Text recognition provides interesting scenarios like cloud based OCR or providing automated translations for texts on images. This blog post focuses on recognizing printed text using Azure Computer Vision API.

Using bearer tokens in ASP.NET Core

There are not much examples available about ASP.NET Core and acquiring access token. I found good and pretty big sample by Microsoft Patterns & Practices called multitenant-saas-guidance, Based on this I wrote my simple “boiler plate” ASP.NET Core solution that authenticates against Azure Active Directory and asks current user data using Microsoft Graph.

Identifying people on photos using Azure Cognitive Services

My previous post about Azure Cognitive Services described how to detect faces on photos. In this post I will focus on identifying people on photos. This post is based on my Azure Cognitive Services sample application that has most of Face API support implemented and the goal is to describe identifying process in brief and also show some code I have written.

Triggering Azure Functions from Office 365 SharePoint using Microsoft Flow

We cannot use classic SharePoint workflows on Office 365 but using Microsoft Flow we can create new era flow applications that are triggered by events that happen in different sources. This blog post shows how to use Microsoft Flow and Azure Functions to send out e-mail when new meeting is added to SharePoint list. The idea of this blog post is to illustrate how to create the flow where custom code takes over in some point.

HTTP-triggered Azure Functions

Azure Functions supports functions that are invoked by HTTP request. It makes it easy to have some scripted functionalities on cloud that we can invoke by simple HTTP request. This blog post shows how to build and run HTTP-triggered Azure Functions using Visual Studio.

Using Azure AD with ASP.NET Core

Azure Active Directory is cloud-based directory service that allows users to use their personal or corporate accounts to log-in to different applications. Local Active Directory can sync data to its cloud counterpart. Also external users are supported. This blog post shows how to make ASP.NET Core application use Azure AD and how to read data that Azure AD provides about user account.

Getting started with Azure Functions

Azure Functions is serverless computing offer by Microsoft. Functions by Microsoft implementation are scripts that can be written in JavaScript, C#, F#, Python, PHP, Bash, Batch or PowerShell. Functions can be developed on Visual Studio using preview level tools or directly through browser in Azure portal. This blog post introduces Azure Functions and shows how to build your first function.

ASP.NET MVC: Precompiling views

This blog post is about how to really precompile ASP.NET MVC views. It destroys the myth about MvcBuildViews as precompilation tool and shows you how to configure precompiling. It also stops on some internals of precompiling and explains what are the options and limitations with it. There is also real-life example for Azure where precompiling of views may avoid some serious headaches that one may face otherwise.

Speaking at TechDays 2016 NL!

This year again I have honour to speak at TechDays 2016 Netherlands. It is well organized event with very good and interesting content. I was speaking there year ago and I had only good experiences with this event. This year it is held in RAI Center at Amsterdam in the beginning of October – 04-05.10.2016.

Azure Search Suggesters: Helping users to find search keywords

Search is important feature of many apps and web sites because it is the main way for users to find quickly the information they are looking for. Typing search keywords to search box is not the end point of search we can provide to users. Sites that have huge amount of data can also help users to find out what keywords to use. In this post I will show how to use Azure Search suggesters to help users to find out these keywords.

Writing simple REST-client for Azure Search

In my last blog post about REST-clients Why Azure REST API-s and how to prepare for using them? I introduced how to write simple base class for Azure REST API-s. In this post we will implement simple REST-client for Azure Search. This is the same code that I’m using in my beer store sample application. I also make some notes about how to use search clients in domain models.

Planning and creating Azure Search indexes

Planning for search is mandatory first step when starting building search index. If we build search indices as we go we easily end up with messed up and hard to use indices. And even worse – we may end up with very complex search queries that need way more resources than we expect. This post goes through simple analysis of example beer store search index and shows how to create Azure Search index for products.

Making Entity Framework 7 and Azure Data Sync work together

I have local database where I insert some data and I want this data to be available also in cloud. As a lazy guy I don’t want to synchronize data manually. After setting up local and cloud databases I activated Azure Data Sync to just find out that it conflicts with EF7 insert and update queries. As I don’t have many tables and my database is pretty small I invented simple workaround.

Beer IoT: Visualizing sensors data using Power BI

We are eager to try out our beer cooling solution and we want to see it in action. We want to visualize our data and keep eye on temperature of cooling beer. Before doing anything more complex like building web or mobile app we make a quick shortcut and bring our data to web, desktop and mobile. This post is about Power BI in action.

Beer IoT: Reporting measurements to Azure IoT Hub

As we have now fully functioning thermal solution running on Windows 10 IoT Core it’s time to focus to other components of our beer freezing solution. Our solution measures and calculates metrics of cooling beer but it doesn’t report this data anywhere. In this blog post we will set up Azure IoT Hub for our solution so it starts reporting measurements to Microsoft Azure.
