Quick tip: access the application log files on Bluemix
Wed, Nov 15th 2017 1:03p   Frank van der Linden
Last night when I deployed a new version of HR Assistant to Bluemix I ran in some troubles. When the application was deployed and tried to access it via de Application URL I got a 500 internal error. Find the log First step was to open the log page, but was not very explanatory. Next step was to open Kibana. There I found more information. As you can see, I need to consult the error-log-0.xml file for more information The challenge is where to find this log file. Solution I started, in my case

HR Assistant – Hello Domino….
Mon, Nov 13th 2017 7:03a   Frank van der Linden
While we developed HR Assistant it ran smoothly on a Domino server, but it was not using some strength of Domino, security. Run on Domino I made HR Assistant aware of the runtime it runs on, it ‘knows’ when it runs on Bluemix. If that is the case our own developed login features comes in place, but… When it runs on Domino it will enforce the ACL, which gave great advantages, by assign groups to the 3 roles of the application, HR, JobApplicant and Administrator. In the end you a

Quick tip: Make a backup of your Cloudant database
Fri, Nov 3rd 2017 3:04p   Frank van der Linden
For HR Assistant, we use Cloudant database as storage of the data on the IBM Cloud Today I was thinking about ‘what if we loose our data as something goes wrong’. It is not likeable, but still possible. Make a backup On IBM Cloud, there is documentation about making a backup of your data. So installed the npm package couchbackup  and run the command as described in the documentation.] I changed only to store the output as a JSON file. When I run the command I hit an error about au

One of the latest features I had add to HR Assistant is multi language support. It was obvious we needed this new features, as not the whole world is talking English One of my goals was to make it as configurable as possible. Default language The default language of the application is still English. All the labels are stored in the application it self as a property file if there are no languages configured these property file will be loaded. On the overview page of the languages is the possibil

HR Assistant – what happened since last year
Fri, Oct 27th 2017 11:12a   Frank van der Linden
Last year I won together with Frédéric Dehédin the ICS Developer Contest 2016 with our HR Assistant application, a cognitive solution to help the HR department with of IBM Watson services. As required the code was open sourced at a public Github repository. What happened with HR Assistant since that moment? From public to closed First thing was to take the code back In the final stage of the development we were not able to include all the features we wanted upfront. So we skipped some featu

Spring boot and Thymeleaf – rapid application development
Fri, Oct 20th 2017 6:02p   Frank van der Linden
At one of my customers I was able to use to build an application with preview functionality of a business critical application. As usual the business wants this application as soon as possible. So the obvious choice was Spring boot in combination with Thymeleaf. Spring Boot Spring boot created spring based applications which can run as a runnable jar, with embedded a Tomcat server. But a Spring boot application can with a few tweaks run on a Websphere Application Server or Websphere Liberty Pro

Quick NPM tip: don’t forget to uninstall node modules
Tue, Jul 4th 2017 4:08p   Frank van der Linden
NPM is great tool to have all your Node modules in your front end project, and don’t have to worry about dependencies. When you find a useful module for your project just do ‘npm install –save-dev’ and you are ready to go, but….. it can pollute your node_modules directory with unused node modules. Just uninstall your unused node module by ‘npm uninstall ’ by The post Quick NPM tip: don’t forget to uninstall node modules appeared first on elstar

Angular 4 bug in combination with latest Typescript
Sat, Jul 1st 2017 10:51a   Frank van der Linden
When we upgraded our Angular app to the latest version. We noticed everything worked with version 4.2.3 and Typescript 2.4. The problem After we reinstalled all the nom packages the Angular version was upgraded to 4.2.4, because we had in our package.json ‘^4.2.3’ for Angular packages. When we package everything and republished the app to the page, we got errors, huh!!!! The solution After some search I found it has to do with the combination of Typescript and Angular

Angular and base64 encoding and decoding
Fri, Jun 30th 2017 7:32p   Frank van der Linden
Currently I am busy building a Proof of Concept at my customer. We are using Springboot for the Backend services, which get data from Tridion and store data in a Oracle database.. The Front end is build with Angular. We started with version 2 with Grunt as build tool, but quickly we changed it to Angular 4 with Webpack. The overall feeling of Angular 4 and Webpack was much better. Another plus was the smaller footprint. Base64 Last request was to store some information in Cookie. Overall no ro

Bulk import in a Cloudant database
Thu, Apr 27th 2017 5:02p   Frank van der Linden
After some issues with HR Assistant I was thinking it would be a good idea to create a separate database with only the Design documents as schema database. So I replicated all the documents from the original database to a brand new one and called it hrassistant_schema. After the successful replication I kept all only the design documents. Today I got a question about the schemas and discovered it should also be a good idea to add all the configuration documents to the schema database of HR Ass

As promised in a previous blogpost, I will zoom in on the technologies I have seen and used at IBM InterConnect I was surprised the amount of technical sessions at InterConnect. More then I then was expecting as lots of people told me It was all about middleware.

IBM InterConnect 2017 – something completely different
Tue, Mar 28th 2017 4:43p   Frank van der Linden
IBM InterConnect 2017 is over, I must say I totally enjoyed it. Lots of attendees, it was crowded everywhere, but it gave a good vibe.  I have met a lot of new people I heard that it was Lotusphere in the old days. I totally agree with the blog by Gabriella Davis, it is time to get out our own yellow bubble and integrate it in InterConnect. There is so much both worlds can learn from each other.

A friend of my will join me on this trip. We will fly to Los Angeles and drive up to Las Vegas. After the conference we will have some time get back to LAX, a sort of mini road trip. Out of my comfort zone IBM InterConnect is a much bigger conference, compared to IBM Connect, at the Mandalay Bay in Las Vegas. It is focused

Yesterday I have created a new release of the OpenNTF project, Generic XPages and HTML Widget For IBM Connections. There was a problem with the widgets in IBM Connections 5.5, which was caused by some tags who were not in the expected DOM structure and small problem in the javascript. But many thanks to Christoph Stoettner of Panagenda who found the solution and provided me the modified files to release. Christoph, Thank you very much for the time you spent on this.

My take on IBM Connect 2017
Mon, Feb 27th 2017 12:30p   Frank van der Linden
IBM Connect went to the west coast of the USA, to the famous Moscone Center in the middle of San Francisco. Last week I have attended and spoken at IBM Connect. Here are some thoughts about the event. San Francisco I had visited San Francisco for 3 years as end point of our road trip through the west coast. I found it and still do it a pleasant city. Not that all American, but with a bit of Europe. It is a very expensive city, especially the hotels. I stayed at Powell Street near Market Street

Bye Eclipse, hello IntelliJ Ultimate
Fri, Feb 3rd 2017 10:33a   Frank van der Linden
In Januari I started on a new role, Full Stack developer at Rabobank. One of the developers in my team is a big fan of IntelliJ from JetBrains, so I gave it a try over the past weeks. I must say I don’t miss Eclipse at all. Currently I am running it on macOS, but also in a VDI of the customer, which runs Windows. What is IntelliJ It is a very complete IDE, not for Java development only, but also Front end development, like AngularJS, because WebStorm is part of IntelliJ Ultimate. Lots o

My evolution as a developer: becoming a Full stack developer
Thu, Dec 8th 2016 8:18p   Frank van der Linden
Is the time of the year to have some time to reflect. Entering the IT Around 2000 I entered the IT world, first as a Domino Administrator, but after a good talk with a former colleague I made the switch to become a Developer. So I became Domino Developer and learned Formula language and later Lotusscript. Did some certifications. When the browser became more important I moved more and more to web development and did some great projects, for example I build the public website of a big insurance
