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.

Updates on the latest Outlook iOS App issues

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.

I’ll be speaking at this years EntwicklerCamp (March 2-4, hosted by IBM Champion Rudi Knegt) about two development topics.

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’

So let’s talk about Extensions and Frameworks. Extensions This will be the most user-visible enhancement of iOS 8 (and Mavericks).

Automate the upgrade of Atlassian Stash on Linux
Mon, Jun 30th 2014 12:12a   Rene Winkelmeyer
Upgrading existing software is sometimes cumbersome. Long checklists, validating pre-conditions, maintaining backups etc. So is it with Atlassian Stash. Stash is an awesome software to manage your Git repositories. As Atlassian delivers often new releases it became tedious for me to upgrade our Stash installation. I wrote a small bash script that now automates the process for me. The script does the following: Read the Stash version number and download URL from a prompt Downloads and unpacks th

WWDC 2014 Recap – Making users and developers happy – Part 1
Thu, Jun 26th 2014 12:11a   Rene Winkelmeyer
As said in my previous post WWDC showed that everything is about the users and the developers. Going through all the changes made it often hard for me to say “that’s only where developers benefit” and “that’s only where users benefit”. So I’ve started to write down some of the major changes that IMHO will affect the ecosystem mostly. But please – no “golden Apple cage” discussions on the things. Apple does everything for their ecosyste

I’m a little late with this post as Apple’s WWDC conference happened nearly three weeks ago. But I don’t like to have things in draft mode – so here we go. The Conference I had the great opportunity to attend this years conference with my colleague Detlev. It was my second visit (first one was 2013). The week was exhausting (as the jet-lag was) and it took and will take some time for me to sort all things out. It’s IMHO outstanding for this conference that you

Need to change Eclipse JRE for OS X 10.10 Yosemite
Fri, Jun 20th 2014 12:05a   Rene Winkelmeyer
When you install Mac OS X 10.10 Yosemite you’ll have to re-install the Java Runtime Environment (JRE). That’s a normal behavior on Mac devices. One thing that’s new here is that Apple has removed QT support. Apple stores in the folder /System/Library/Java/Extension additional files which supplement the JRE installation. Now with Yosemite the files QTJava.zip and libQTNative.jnilib are no longer part of the extensions. Depending on your JRE setup in Eclipse you now have to go

Detecting Domino bitness in pure Java
Mon, Apr 28th 2014 2:30a   Rene Winkelmeyer
For a recent project I had to determine the bitness of IBM Domino in pure Java. One may ask if there is a reason to have that information. In my case I wanted to call some included native C libraries via JNI within an OSGi plug-in. And calling i. e. a 64bit library on a 32bit system…well…that just won’t work. I didn’t wanted to go with the assumption that on a 64bit operating system always 64bit Domino runs. As I’m serving “only” Linux and Windows the nu

IBM Collaboration QuickStart image on SoftLayer – stumbling setup process
Fri, Feb 7th 2014 1:02a   Rene Winkelmeyer
I really like the idea behind the IBM Collaboration QuickStart image on SoftLayer (Niklas posted here). Helping new developers to get in touch with ICS technologies without going through installation hell. Personally I like to test things before I recommend them to others. So did I with the QuickStart image. Or better – with the SoftLayer account creation process. On slide 17 in the above link Paul Bastide has stated “We are going to skip the account setup…”.

Native app? Hybrid app? Some thoughts…
Mon, Feb 3rd 2014 1:01a   Rene Winkelmeyer
Some – for me – highly respected people demonstrated last week at Connect 2014 how to build mobile apps using IBM Worklight. It was nice to see how the tooling works as I haven’t looked into Worklight very deeply. At least because I don’t want to install another Eclipse and because Worklight doesn’t support the latest Eclipse version 4.3. I’ve often heard the wording “native apps” in the context of those sessions. So what does that mean –

Watch out when having ShortName synchronized with Traveler and iOS 7
Tue, Jul 16th 2013 3:12a   Rene Winkelmeyer
Today I’ve been pointed to an interesting behavior when having the ShortName field filled in your personal addressbook and iOS 7. Thanks to Harald “Shadow” Gärttner for this. So what does happen: The shortname field in the personal addressbook has always been used as the nickname in iOS. That’s very convenient when using voice commands, addressing e-mail and so on. A lot of people store the people’s nicknames in their personal address books (besides the peopleR

Upcoming blog series – Understanding IBM Domino HTTP
Mon, Jul 15th 2013 9:49a   Rene Winkelmeyer
Due to some recent (and past) development stuff I took the chance to dig deeper into the different IBM Domino HTTP containers. Did I say “containers”? Plural? Yes – I did. IBM Domino HTTP has received some major changes in the last years. It has evolved from running static web sited and “classic” Domino web applications (+ a nowadays outdated servlet engine) to a fully functional OSGi and J2EE web server. This is no new stuff. IBM has told us about those changes oft

Simple helper method for Domino object recycling

Recycle, recycle, recycle
Wed, Feb 27th 2013 1:14a   Rene Winkelmeyer
Yesterday I stumbled upon a behavior which directed me – once again – to the most important point in Notes/Domino Java develoment. Recycling! As you probably know recycling is special to Notes/Domino Java development. It frees the handle on the backend C element. If you don’t recycle you’ll have “ghost” objects in your Java environment. That’s bad. It may cost you memory. And…it may lead to wrong results. If you’re doing “classic”

I’ll be speaking at EntwicklerCamp and BLUG. Two events, two weeks, two different topics, triple fun. I’m honored. Again. Honored to share my knowledge. Honored to meet well-known people again. Honored to meet new people. The time after Lotus…ahem…Connect is the time before PutYourFavoriteConferenceNameInHere. It’ll start for me with Rudi Knegt’s EntwicklerCamp (11.-13.03.2013, Gelsenkirchen, Germany) and Theo Heselmans BLUG (21.-22.03.2013, Leuven, Belgium).
