Time to revisit my VIM plugin system after VIM is upgraded to version 8.0
Previously I was using Vundle but it is bit complicate to set up quickly. This time I am using vim-plug.

Jump-start ASP.Net Core with Docker
Environment Setup
I have a typical developers environment: Windows 10 Enterprise X64 (Version 1511, OS build 10586.839). Installed DotNet Core 1.0.1 and VS Code. In VS Code there are two extension installed.
Enable Hyper-V
VirtualBox is no longer needed! Simply enable the Hyper-V on on Windows 10 by running powershell commands (as Administrator)
1 | Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All |
You might need to change the BIOS setting. Read more at here.
Note:
The document from Docker also mentioned that the virtualization must be enabled, and said you can verify it in the Task Manager. However, I can not find “Virtualization” label in my Task Manager. But the following steps work fine anyway.
Install Docker
Head to Docker official site, download and install Docker for Windows. The version I installed was 17.03.1-ce, build c6d412e Community Edition, via Edge channel.
Lets verify it.
Review and manage your web site disk space in Azure
Problem
We have a large distributed system which is hosted in Azure. The front end web application are Azure web sites.
From time to time, the web applications were down, due to running out disk space in the Azure web sites. Our operation team would like to quickly identify what are the large files and how we can free up disk space in Azure web sites.
Lucky, Azure application service already provides a nice tool for this type of work: Kudu service.
Announcing new version of DNV GL Rules Chatbot
Happy new year!
I am happy to announce the new version of Rules Chatbot is ready now. The key new features are below:
- Support full text search (based on SharePoint Search)
- Indexing DNV GL classification rules documents with enhanced metadata
- Customized ranking
- Upgraded to Bot Framework 3.0
No agent pool found with identifier 0 error when setup build agent in VSTS
Problem
We cannot register a private build agent on VSTS by using a service account. This service account has created Personal Access Token with expiration for 1 year and authorization for all scopes.
Whenever we run the config.cmd, then connecting to the server, type the Agent Pool and Agent Name, configuration command throws error.
No agent pool found with identifier 0.
Failed to add the agent. Try again or ctrl-c to quit
However, with the same build server and with another developer’s account, it works fine and the build agent is up and running.
Work with custom event in Application Insights
Application Insights can offer you lots of built-in telemetries such as Page Views and Exceptions. But quite often we need to track some customize/business performances. Some examples that we are using now are:
- SharePoint crawled items from content source X
- Daily usage of a web application of all users from company ABC
- Usage and performance of different version of API
To meet these challenges, Application Insights offers API for custom event and metrics.
In this article I will show how to monitor and analysis API performance by using custom events, including export it into external database for archiving and future analysis.
Web/Load testing against an ADFS federated application
In Application Insights, you can create an availability web testing to monitor the availability of a web application. It supports 2 type of testing:
- URL ping test: a simple test that you can create in the Azure portal.
- Multi-step web test: which you create in Visual Studio Ultimate or Visual Studio Enterprise and upload to the portal.
Normally it is easy to setup ping test and multiple step testing against a public site.
However, in order to have a multiple step testing against an ADFS federated application, you will have to do some extra in order to take care of the authentication part.
Application Insights Export and PowerBI
Introduction
Application Insight is a great tool for monitoring your application. However, there is a limitation regarding historical data: Regardless the different plans, you can only have:
- 7 days raw data, includes access to all telemetry data points collected by application insights
- 90 days aggregated data, includes access to telemetry data points aggregated at hourly/daily levels
This article will demonstrate how to use the continuous data export to overcome this limitation, as well as use PowerBI for future web analytic.
A chatbot prototype - DNV GL rules and standard chatbot
(Edited 2017-01-07: The newer version of Chatbot is at here).
At the end of March 2016, Microsoft announced the Bot Framework, a platform that helps you to quickly build the high quality bots for your business.
In April, after a long weekend happy hacking, I have built a chatbot prototype who can help you to find DNV GL service document.
How to connect VSTS project and Azure subscription
Introduction
For enabling the continues deployment from VSTS to Azure, e.g. provision the environment and deploy code, you must create connection between VSTS project and Azure subscription. It should be done in individual project and not in the VSTS top level. Therefore, each project can connect to different Azure subscription.
It contains two main parts, and normally you need both of them
- Connect Azure Classic (for deploying your application code)
- Connect Azure Resource Manager (for provisioning your environment)
