Watson Studio project restriction for collaborators

When we create a Watson Studio project, we should pay attention on the collaborator restriction! We cannot change it later.

This is just a blog post about a common pitfall for new Watson Studio users , when they are creating a new Watson Studio project.

The step five in the documentation of the project creation tells us about restrict who can be a collaborator for our project. This configuration has a huge impact for our user access management later, by just checking this small box.

watson-studio-restiction

Step five says:  Select the Restrict who can be a collaborator check box to restrict collaborators to members of your organization or integrate with a catalog. The check box is selected by default if you are a member of a catalog. You can’t change this setting after you create the project.

This is not the end of the world, we can easily create new projects, and configure them. Even I would say, this is a good opportunity to get familiar with the user management of IBM Cloud anyway.

State management, modal dialog and simple spinner in VUE

This blog post is about how to use state managementspinner with conditions, and modal dialogs when saving data in VUE. How these works, we will explore along an implementation in the #BlueCloudMirror project. Maybe this can save you some time, if you plan to do the same.

Let’s start with my motivation, we want to improve our #BlueCloudMirror game UI. If you saved your scores data in the previous version, you were routed back to start game page. You received no information, if storing your data was successful in the highscores list.

In the new UI you can see the saving progress and you get confirmation when your data is saved, as you can see in the gif below.

To understand how this works in VUE, we need to touch the following topics:

We will use the Results.vue and State.ts source code files from the #BlueCloudMirror github project, to see how it works in the #BlueCloudMirror  game.

How to create an interactive YouTube Video selection in VUE

In this blog post I want to share my observations during my implementation of an interactive YouTube Video selection in VUE. Maybe this can save you some time, if you plan to do the same.

Let’s start with my motivation, it came from the improvements of the #BlueCloudMirror game UI. We decided to provide the #BlueCloudMirror users a recorded YouTube LiveStream of us. This video provides an awesome overview of our  major technologies.

The video takes approximately 50 minutes. This is a long time to watch, so we want to provide the user a new interactive architecture page, as you can see below. A user should have the ability to select the topic he is interested in. To do this, we needed the position selection for the YouTube video. In the gif you can see the result.

Topics of this blog post:

  • How to define dynamic values in a VUE template
  • How to configure autostart for YouTube videos
  • How to avoid SAMEORI problem with the YouTube video

Cors and Node-RED using a simple forwarding server

When you use Node-RED on IBM Cloud during hackathons you will notice REST calls in flows cannot be directly invoked from a web application. The reason for this is mostly that cors (cross-origin resource sharing) is not enabled for the Node-RED server. This blog post is a simple workaround for this problem.

I developed this workaround to have full control and be very flexible during a hackathon, when using Node-RED for prototyping and building integrations to services and web-applications, without changing Node-RED settings or using cors browser enabler.

How to deploy a container to the IBM Cloud Kubernetes service

I want to describe another way to run the  Highscores-Service of the #BlueCloudMirror game . In the game I use  IBM Cloud Foundry apps, now I want to explore IBM Cloud Kubernetes.

Note: The #BlueCloudMirror game we  @Niklas, @Harald and I made, is available as an Pattern on IBM Developer.

The first step was creating a container for the Highscores-Service,  which I described in my blog post how to build a container.

In this post I deploy my scores-service container to the IBM Cloud Kubernetes service.  This is  not a blueprint for IBM Kubernetes deployments, if you looking for a blueprint,  just take a look hereIBM Cloud documentation contains a great guide for getting started:  How to setup and use IBM Cloud Kubernetes

I share my experiences and observations with you, along with my deployment.

Let’s start with an overview of the topics I touch in this blog post:

Simplified Architecture

The above picture shows a simplified architecture for the scores-service inside Kubernetes. You can see the relevant elements for the deployment. If you are interested in the details of  these elements, just click on the linked Kubernetes documentation.

#BlueCloudMirror Game – highscores

I am a part of the team along with @Niklas and @Harald , who created and developed the fun Blue Cloud Mirror Game. 

game

This is my first blog  about this topic, and I will follow with future posts to detail the different parts of highscores (scores) and the technologies and components involved.

You can also take a look at other existing information:

The motivation for the highscores (scores)

If you play a game, you usually want to compare yourself with others. To do this, you simply have to save scoring information somewhere and provide access for the players who want to see the highscores, even if they do not play the game.

The high-level architecture overview on scores

The objective was to implement this on the cloud with state-of-the-art runtimes, services, security topics, to cover microservices, and to have an easy scalable cloud architecture.
I developed the scores part and the functions-api for users.

scores-architecture

The Game, Scores Service UI and the Highscores webapp are hosted on different runtimes and for the execution they will be loaded into a browser.

Cloud Foundry on top of Kubernetes @IBM Cloud – a small test

This blog is related to the topics Cloud Foundry Enterprise Environment , serverless , code patterns and the IBM Coder Program.

I just want to move an existing Cloud Foundry app on IBM Cloud to the new IBM Cloud Foundry Enterprise Environment,which instantiates Cloud Foundry on top of Kubernetes. You can find more details about this IBM Cloud offering in this blog post “An on-demand, single-tenant Platform-as-a-Service on IBM Cloudfrom IBM.

Motivation

Maybe you noticed the section Combined Power in my blog post Operations and Developers side by side @“Continuous Lifecycle” and “Container Conf” related to Simon Moser’s session CF3 – Combining the Power of Cloud Foundry and Kubernetes” ? In this blog post you can read more about the motivation to combine the power.  Also you can find out which open source projects ( eirini for example) are relevant.

Based on  Simon Moser´s speech, I was motivated to check out the Cloud Foundry Enterprise Environment on IBM Cloud.

I started my test of moving an existing Could Foundry App. I have chosen to move the app instance from one of my modified code patterns . My selection was the Predictive Industrial Visual Analysis. This code pattern has a big focus on serverless, but I will write more about the serverless part in the near future.

Let’s get started: How do I move an existing Cloud Foundry app?

How to enter your promo code in the newer IBM Cloud UI? (UPDATE)

This is just a small update to my blog post Promo code and free Kubernetes Cluster @IBM Cloud specific to the topic promo codes.

Currently IBM Cloud provides two UIs to access the IBM Cloud.
But don’t be afraid, when entering your code, this will work for both of them.

You can access the newer unified UI, with more functionalities, via http://cloud.ibm.com and the traditional UI you can access with www.bluemix.net.

If you enter your promo code in the newer UI just follow these steps:

  • Open Manage->Account in the IBM Cloud UI menu
  • In Account select Account settings
  • Here you can enter your promo code in Feature (Promo) Codes

cloud-ibm-ui-20181204

The creation of the free Kubernetes Cluster has not changed.

I hope this was useful for you and let’s see what’s next?

Greetings,

Thomas

Let‘s Code Pattern 02: Diversity and Inclusion – ensure loan fairness

The good combination of IBM coder program  and code patterns motivated me to dig in into the data science area a little bit, relating to the real-world topic diversity and inclusion . Also it was interesting to see: How the AI Fairness 360 toolkit, which is an open-source library to help detect and remove bias in machine learning models, can be used for data science in this context.

The diversity and inclusion topic started with a good statement:

Diversity and inclusion is more than a checkbox, it’s fuel for growth and success in any business or community.” IBM Coder Program.

This was one reason why I completed the challenges of the Diversity and Inclusion topic in the IBM coder program .

The IBM coder program

If you don’t know the IBM coder program, just visit this  link .
The program is about:

  • Growing skillset and reputation
  • Discovering and transparently discuss content 
  • Being rewarded with various tangible and intangible rewards

The code pattern Ensure loan fairness  was one of the challenges for Diversity and Inclusion topic.

Code pattern “Ensure loan fairness”

This code pattern is about machine learning with artificial intelligence, data science and python. It gives an introduction in how to use the AIF360 tool kit .

  • “The AI Fairness 360 toolkit is an open-source library to help detect and remove bias in machine learning models. The AI Fairness 360 Python package includes a comprehensive set of metrics for datasets and models to test for biases, explanations for these metrics, and algorithms to mitigate bias in datasets and models.“

In the related demo on IBM research-trusted UI, you can verify given ai models with different datasets and the bias mitigation algorithms .
