Monday is present day – thank you LDC Via, thank you IBM
Mon, Jun 22nd 2015 10:25a   Rene Winkelmeyer
Today I received two packets with gifts… First I received a present from the nice guys (thanks Mark, Matt, Julian and Ben) at LDC Via. An external battery with 25,600 mAh. So enough power to survive a full conference. The second packet came via FedEx and contained my IBM Champion swag. Besides the usual lanyard and pin I’ve ordered a messenger bag and a small luggage trolley. And I really like the quality. Thanks Amanda and Oli! All that arrived just in time. I’ll str

Hiding Domino HTTP authentication in Vaadin applications
Thu, Jun 18th 2015 1:45a   Rene Winkelmeyer
All web based applications that I’m building nowadays are based on Vaadin. If you haven’t heard of this framework I highly recommend to check it out. One of the benefits of Vaadin is that you can run the same application on multiple server platforms. Those platforms are in our case IBM Domino and IBM WebSphere Liberty. Serving different platforms also means to work with different authentication mechanisms. You can use either the “application authentication” or the “

Using the Websphere Liberty Profile Maven repo with Gradle
Tue, Jun 16th 2015 4:34a   Rene Winkelmeyer
This is obviously not a biggy, so mainly a short reminder for myself. For the current development we’re using the Websphere Liberty Profile (WLP) a lot. Based on our latest efforts of moving everything to Gradle I ran into the situation to setup the WLP repos for that. IBM has described here how to add the WLP libraries to a local repo. As described hereWhen using Maven repositories you may refer to the most current version (if supported) with the LATEST tag. That may not always work well

Using remote TLS/SSL systems with untrusted Certification Authorities in IBM Domino 9+
Tue, Jun 2nd 2015 2:09a   Rene Winkelmeyer
One of the best kept secrets starting with Domino 9 is how to handle TLS/SSL connections to untrusted 3rd party Certification Authorities. I’m not going into detail what TLS/SSL means. There are thousands of websites explaining it already. The important point for this blog post is that the requesting system needs to trust the Certification Authority (CA) which issued the SSL certificate of the target system. If it doesn’t trust (aka “knows”) the CA it normally will thro

Self-signed SSL host certificates are for beginners
Mon, May 4th 2015 11:52a   Rene Winkelmeyer
I normally don’t rant. But in the last days I’ve seen in various occasions comments about stuff that’s not working with a self-signed SSL host certificate. I’m seeing this especially in the Domino area where it was (is) easy to create a simple self-signed SSL host certificate for server xyz.company.com. In my opinion too easy. Even if it’s only for a very specific purpose (like giving a few users access to a web/mobile service) the good – and only – prac

IBM Verse for iOS (iPhone to be specific) is now available
Thu, Apr 30th 2015 1:10a   Rene Winkelmeyer
Yesterday IBM has published the new iOS (iPhone) app “IBM Verse”. You can get it here in the Apple App Store. You can use the app if you’re an IBM Connections Cloud customer (S1 offering). Or – if you’re running your mail on -premises you’ll have to run IBM Traveler 9.0.1.3 (minimum, better the also yesterday released 9.0.1.4). So what can you expect from the app? Mainly two things: Containerized PIM (mail, calendar, contacts) access Access to the IBM Verse

WWDC 2015 – I’m going

I’ve been selected to buy a ticket for WWDC 2015. After being fast enough in 2013 and having some luck in 2014 I’m now again lucky as being selected by the Apple lottery to go to WWDC. What can I expect? Nearly 12h in a plane – twice 9h time-difference (hello jet-lag) 100 sessions by Apple engineers Large labs with 1,000 Apple engineers at your fingertips Long queuing times for the sessions and the lab appointments 10 exhausting conference hours each day and much more!

IBM has released IBM Notes Traveler version 9.0.1.3 with some really nice changes. Read the official documentation here. The main changes are: Support for the upcoming iOS app “IBM Verse”. Now the gap is closed and you can run your own “PIM container” delivered by IBM. The app isn’t available yet but will be soon. Support for the synching the Trash folder on iOS. Finally. Using GCM (Google Cloud Messaging) for notifying Android devices about new mails. That’

Updates on the latest Outlook iOS App issues
Sun, Feb 1st 2015 11:29a   Rene Winkelmeyer
First of all: I haven’t expected that my previous blog post would create such a buzz… As I’ve received a great number of comment, mails, re-posts, re-tweets and so forth I’m taking this to get into some more details. Some background about me I spent the last four years nearly exclusively in the mobile area in building products for Mobile Device Management, Mobile File Sharing and securing Mobile PIM.

Warning ? Microsofts Outlook app for iOS breaks your company security
Thu, Jan 29th 2015 11:04a   Rene Winkelmeyer
Microsoft has released their iOS for Outlook today. And it will break your companies security for mobile PIM access in multiple ways! No matter if you’re a Microsoft Exchange or IBM Notes Traveler customer. I cannot believe that Microsoft has done what they’ve done. Even as a non-Microsoft guy I would have expected that they obey the rules of common company security rules. File sharing capabilities The app has built-in connectors to OneDrive, Dropbox and Google Drive. That means a

Speaking at EntwicklerCamp about iOS and Vaadin development

I’ll be speaking at this years EntwicklerCamp (March 2-4, hosted by IBM Champion Rudi Knegt) about two development topics. From Idea to App “We need this data available on our mobile devices.” – an often heard requirement these days. But what needs to be done to achieve this? Learn in this session the steps to use your data, like that in IBM Domino, within a native iOS app. You’ll get a grasp on the MVC pattern in the Xcode IDE and see the benefits of the new Swift programming la

Vaadin certified
Tue, Jan 13th 2015 12:05a   Rene Winkelmeyer
I’m a big fan of proving my knowledge. Not only in my day-to-day job, but also in testing my (theoretical) knowledge in doing certification tests. As of yesterday I went down the road of becoming a Vaadin 7 Certified Developer.

Vaadin does client-side debugging right
Wed, Jan 7th 2015 12:16a   Rene Winkelmeyer
One of the caveats when using server-side frameworks is that you often don’t have real debugging possibilities for the client-side generated code. There are often no built-in tools to help the developer with that. In the XPages world for example the XPages Debug Toolbar (created by Mark Leusink) should be, besides the usual tools like Web Inspector or Firebug, your weapon of choice. As I’m not really into XPages any longer – honestly, never have been really deep into them &#

Explaining Certificate Authentication – 101 style
Mon, Jul 14th 2014 12:11a   Rene Winkelmeyer
Less people know that one of my pet technologies I’ve worked with in the last years was everything around certificates. I’m not talking about SSL for websites only, more about using certificate-based technology in general. The reasons why I started with certificates was the incorporation of this piece of technology within different areas of our companies products. That has extended by time into other areas. Projects I’ve worked in and with involved for example: automatic ce

WWDC 2014 Recap – Making users and developers happy – Part 3

Here comes post no. 3 about WWDC 2014 (the last one in this series). So let’s see how to make users and developers happy. Generic Size Classes That’s in my opinion a huge improvement. So what does that mean “Generic Size Classes”? If you develop nowadays an app for you will use a Storyboard for the visual design. As iPhones and iPads have different variations of screen real estate one would normally have two Storyboards: one for iPhones, one for iPads. And that’

WWDC 2014 Recap – Making users and developers happy – Part 2
Mon, Jul 7th 2014 12:05a   Rene Winkelmeyer
After describing the benefits of the upcoming changes regarding iCloud in my previous post about WWDC 2014 (I know – I’m late) I’m now talking about some more technical stuff. So let’s talk about Extensions and Frameworks. Extensions This will be the most user-visible enhancement of iOS 8 (and Mavericks). You know Apple and their restrictive handling of inter-app communication? Some people think it’s a curse, that apps aren’t allowed to communicate directly
