The 43. DNUG conference is happening soon – (22 years of DNUG!) – join us|
Wed, May 4th 2016 2:45a Rene Winkelmeyer
Yes, 22 years of DNUG! Isn’t that awesome?! It’s like a full millenium in the technology world. Let’s celebrate that with the 43. DNUG conference which will take place on June 1st to 2nd 2016 in Hamburg.
We’ve worked hard in the different tracks to put together a great lineup.
Checkout the full agenda on http://43.dnug.de. Registration can be done via EventBrite.
Special thanks here to Niklas Heidloff, Andreas Rosen and Jochen Prieß who worked with me in the AppDev
If you’re a speaker or want to be a speaker – listen to this guy|
Thu, Apr 14th 2016 1:37a Rene Winkelmeyer
This is what it is all about…
I can still taste the haggis on my first speakers dinner ever (where I met “Dr. Evil” aka Fabrizio Marchesano). And my nervousness of my first speaking session.
Plus I got my first speakers LEGO sculpture (thanks to Kitty and Warren for that, see the pattern).
Stand up and speak! At a conference, at a user group or at a local meetup. Don’t be afraid! It was – and is – all worth i
Join the “first” IBM Social Business Community Meeting on April 13th|
Fri, Mar 18th 2016 2:35a Rene Winkelmeyer
With the change from the 3rd party hosted community site (formerly ran under socialbizu.org, now down) to an IBM hosted site it’s time for the first Community Meeting.
IBM’s awesome Community Manager Amanda Bauman has announced the very first meeting on the new site to introduce the new site and her goals for User Groups in general. It’s the kickoff for a new series of upcoming meetings.
If you haven’t joined the Community till now – do it! Just go to the comm

First impressions of IBM Verse Offline Mode|
Tue, Mar 15th 2016 7:24a Rene Winkelmeyer
As IBM has announced on this years IBM Connect conference the long awaited offline functionality for IBM Verse is now available.
So I activated it to see what’s in (and what’s not).
When switching to the Offline Mode you’ll be asked to enter your offline password (you can read on Matteo’s blog how to enable the Offline Mode in your account, there you’ve to define your password).
The dialog pops also up when first opening Verse, so that you can decide if yo
Developers – put your thinking hat on – the 43. DNUG conference is happening on June 1+2 in Hamburg|
Tue, Mar 15th 2016 2:45a Rene Winkelmeyer
If you’re a developer and want to speak at one of the worlds oldest ICS related User Groups it’s time to put your thinking hat on. The German Notes User Group (DNUG, obviously not only about “only” Notes anymore) has opened it’s call for abstracts.
What is it about?
I’m running the development track for the conference with Niklas Heidloff, Andreas Rosen and Jochen Priess. We’re looking forward to your highly technical content. Here is a personal list o
Speaking at engage.ug – Moving from Java 6 to Java 8|
Mon, Feb 29th 2016 2:27a Rene Winkelmeyer
It’s speaking season. And it’s engage.ug – the largest ICS User Group meeting in Europe.
This time I’ll be speaking about a – in my opinion – very important topic for any developer that does Java development. Especially in the ICS space. As IBM has announced last year (and re-announced at IBM Connect in February) they’ll make concurrency updates to the IBM J9 JVM. Finally they are moving from Java 6 to Java 8. That brings great enhancements to a develope

How to download all IBM Connect 2016 presentations at once|
Tue, Feb 9th 2016 5:30a Rene Winkelmeyer
This time it’s quite easy, no download script or else is needed.
As IBM leverages IBM Connections for storing the attendee and session details in the background one can easily access all files at ones.
The data is stored in the IBM Connect 2016 community which can be accessed by attendees here (you’ll need to use your ibmeventconnect.com credentials for that). The files are stored in the Files section.
From there you can download the files you need. Or use this link to download
App black- and whitelisting for ALL apps arrives on iOS soon|
Fri, Jan 15th 2016 1:56a Rene Winkelmeyer
My colleague Detlev blogged yesterday already about the capability of hiding iOS system apps coming with iOS 9.3 (in beta at the moment, originally posted on CultOfMac and Reddit).
After some further analysis I’ve to wider the target for that: the new feature will allow you to much more!
By going through the specs and doing some testing it is obvious that you can allow/disallow any app on an iOS device soon. Which means in fact that you’ll have full capabilities for app black- a
bleedyellow.com has a new owner|
Mon, Jan 11th 2016 1:45a Rene Winkelmeyer
For those who are not familiar with the domain name: an US-based IBM Business Partner (Lotus911.com) has initially provided several community services for free on that domain, like a hosted IBM Connections and IBM Sametime environment. Group Business Software (GBS) has continued to provide those services after they’ve acquired Lotus911 in 2009.
Mid last year the services have been shut down by GBS. Silently and without any prior notice (not a good practice IMHO). Which means t
Proof of Concept – Migrating Notes RichText to Markdown – Part III|
Wed, Jan 6th 2016 2:01a Rene Winkelmeyer
In this last post I’ll give you a walkthrough of this PoC. The full source code is available on GitHub (see end of the post).
The simplified code example
As I’ve described in my previous post I’m going to read all entries in a given view using the ReadViewEntries URL parameter. Read more about it in this cheat sheet (from 2002!). The call gives us basically one root element with a “viewentry” array. The array contains all documents, categories etc. as siblings. So
Proof of Concept – Migrating Notes RichText to Markdown – Part II|
Tue, Jan 5th 2016 2:29a Rene Winkelmeyer
As explained here there are some preconditions that have to be met for the conversion. The real-life usage may (and should) be more enhanced. But I wanted to provide a way that achieves the goal in a (hopefully) simple way – so that everybody can easily re-create the results for him- or herself.
You can get the content of a NotesRichText field in three different flavors:
native NotesRichText (or DXL)
The content of a RichText field can i. e. be stored as
Proof of Concept – Migrating Notes RichText to Markdown – Part I|
Mon, Jan 4th 2016 2:41a Rene Winkelmeyer
First of all: this is not a blog post about “how to move my data to another platform”. It is about combining several (long) existing technologies to move some of your structured data to a lossless format like Markdown.
But lets start from the beginning (aka: the use case).
Most organizations have standardized content like organizational rules or application documentation stored in Notes databases. Which is totally fine when you (only) have to deliver that content to IBM Notes clie
I’m an IBM Champion 2016 – and my colleagues are, too|
Tue, Nov 24th 2015 1:55a Rene Winkelmeyer
As of yesterday IBM has announced the class of IBM Champions for Enterprise Social Solutions for 2016. You can find the detailed announcement here.
I’m excited to see the movement in the selected Champions. Lots of first-timers and returning (former) Champions. The list includes some of the smartest people in this space – and some of the nicest. Pick what you’re. 😉
What makes me especially happy is the fact that we’re now three(!) IBM Champions in our company. Besid
Sessions accepted – Speaking at IBM Connect 2016|
Mon, Nov 23rd 2015 2:04a Rene Winkelmeyer
It’t the time of the year when we’ll get notice if we can speak at IBM Connect (aka Lotusphere) or not. Luckily I’ve been accepted for two sessions this time.
Going Mobile with IBM Verse
IBM Verse is IBM’s answer about working with your day-to-day workhorse, email, in a simple, easy and collaborative way. And native applications play a major part in leveraging the #NewWayToWork on mobile devices. This session will show you the “what” and “why” of
IBM Bluemix and Vaadin are doing it right – the challenge|
Mon, Oct 5th 2015 1:54a Rene Winkelmeyer
I’m a big fan of Vaadin as an UI framework as readers of my blog may have noticed. And I like what IBM is doing in the Bluemix space. Now they’ve joined for a challenge (or contest as some may say).
The challenge itself contains of nine tasks. Some give you fixed boundaries to interact in, others not. The list of tasks is freely available here. You can see how many people have submitted a task for review below the “person” image on the left side. The description of
Busy November ahead – Speaking at Social Connections and SUTOL|
Thu, Oct 1st 2015 3:05a Rene Winkelmeyer
End of October and beginning of November will be busy for me. After speaking at SNoUG (blogged about that here) I’ll head nearly straightforward to Social Connections in Stuttgart and SUTOL in Prague. And in between I’m very happy to introduce Ulrich as a new member of my team to the development stuff we’re doing here at midpoints.
This time my speaking will cover a broad range of topics, going from IBM Connections integration along to Vaadin development up to Software Quality
IBM Notes 9.0.2 for Mac OS X is there (yeah, you read it correctly, 9.0.2)|
Tue, Sep 29th 2015 8:57a Rene Winkelmeyer
IBM has published a new release of IBM Notes for Mac OS X. Legally it’s 9.0.1 – technically it’s 9.0.2.
With the upcoming (tomorrow) release of Mac OS X El Capital 10.11 IBM had to deliver an update to the IBM Notes Client so that it leverages Java 8 as runtime for the Eclipse based client.
If you take a look at the insights of the package you can see that the underlying codebase is already 9.0.2 – and not 9.0.1 as the package name says. So technically Mac users are n
IBM Domino 9.0.1 FP4 IF2 is available NOW – Full support for El Capitan and iOS 9 ATS|
Fri, Sep 25th 2015 9:13a Rene Winkelmeyer
IBM has released IF2 for IBM Domino FP4 IF2 right NOW which supports the latest ECDHE ciphers. And with that ATS (App Transport Security) on iOS and Mac OS X El Capitan.
I’ve spoken here and here about it. IBM has delivered fast – many thanks!
Information about the IF2 => here.

It’s this time of the year – Nominate your IBM Champions!|
Mon, Sep 14th 2015 4:48a Rene Winkelmeyer
Once in a year is nomination time for the new IBM Champions. And it has started today!
So what is an IBM Champion?
The IBM Champion program recognizes innovative thought leaders in the technical community — and rewards these contributors by amplifying their voice and increasing their sphere of influence. An IBM Champion is an IT professional, business leader, developer, or educator who influences and mentors others to help them make best use of IBM software, solutions, and services.
Zurich here I come – speaking at SNoUG about Vaadin|
Fri, Sep 4th 2015 12:59a Rene Winkelmeyer
I’ve been accepted for speaking at the annual Swiss Notes User Group meeting in Zurich, which takes place at 28th October 2015. With a provocative session (title).
Vaadin – XPages 2.0?
You’re doing XPages and Java? Good. You want to embrace the gained knowledge? Better. The Java-based Vaadin framework allows you to easily build web applications which have an appealing UI and run on different app server like IBM Domino or IBM WebSphere Liberty – without any code changes
Last warning (if you haven’t heard about it) – Apple will enforce ATS on iOS 9 compiled apps|
Thu, Aug 27th 2015 12:19p Rene Winkelmeyer
A few weeks ago I wrote that it is important to support the specs for Apple’s new App Transport Security (ATS). Here is the proof of what will happen.
I compiled an app with the iOS 9 SDK and connected it to current IBM Domino 9.0.1 FP4 server (with DEBUG_SSL_ALL=3 activated). As you can see in the output the client has requested an unknown cipher – and with that hasn’t setup the SSL connection.

Compiling Vaadin widgetsets for Domino|
Wed, Aug 26th 2015 1:11a Rene Winkelmeyer
I a recent Skype chat I had with Paul Withers he pointed out that he had some problems to compile the widgetsets for Vaadin add-ons from Eclipse when developing them for the IBM Domino platform. That reminded me that I stumbled upon that problem a year ago or so. Time to document the solution. 😉
I’ve written and talked in the past that my preferred web framework is nowadays Vaadin. Vaadin uses so called widgets which represent the UI in the browser application which is then tied to so
“Gradle Up!” – or I’ll speaking at ICONUK 2015|
Mon, Aug 10th 2015 4:02a Rene Winkelmeyer
I’ll be speaking at ICONUK this year which takes place from September 21 to 22 in London.
As software development projects grow, the need for tooling grows. Where copy & paste of needed libraries or manual project configuration was “ok” in the past it’s nowadays standard to automate these tasks. Especially when you’re stepping into the world of Continous Integration (CI). But getting there sounds easier as it is.
This session shows you how to leverage t
Meetups, usergroups, conferences and YOU are the blood in the body of each technology|
Thu, Aug 6th 2015 2:42a Rene Winkelmeyer
This is a post that I wanted to write for a long time. I’ve never really finished my thoughts, but I think it’s now time to get that out of my head.
Let’s start with a very important statement: I won’t write about a specific technology or vendor in here. What I want to say is about technology – and passion – in general. Even if my experience is mainly bound to some specific technology.
For the last 16 years I’ve business-wise mainly worked with IBMR
Update your SSL on servers to support TLS 1.2 BEFORE iOS 9 and OS X 10.11|
Tue, Jul 14th 2015 1:00p Rene Winkelmeyer
I recently learned that there are still people around there who haven’t their servers (Apache, Domino, whatever) updated to support TLS 1.2. If you belong to this group and you’ve iOS devices (or Macs) accessing that server: read and act!
Apple is introducing App Transport Security (ATS) with iOS 9 and OS X 10.11. The purpose of ATS is to leverage best practice security data connections.
Here is an excerpt for the current pre-release documentation:

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
