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.
The direct download list is available 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.
27.08.2015 17:52:11,89 SSLProcessClientHello> Client requested Unknown Cipher

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.

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
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 126.96.36.199 (minimum, better the also yesterday released 188.8.131.52).
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|
Sat, Apr 18th 2015 6:22a Rene Winkelmeyer
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!

Wed, Apr 1st 2015 4:50a Rene Winkelmeyer
IBM has released IBM Notes Traveler version 220.127.116.11 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’

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. Not talking about my experience in several administration topics inclu
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

“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
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
