Domino meets RXJava
Tue, Sep 13th 2016 7:33a   Stephan H Wissel
Verse on premises (VoP) is nearing its second beta release and fellow Notes experts are wondering if they need to install Apache Solr as part of the VoP deployment. There was a lengthy, high quality discussion and quite some effort evaluating alternatives. In conclusion it was decided to deliver the subset of Solr capabilities needed for VoP as series of OSGi plugins to the Domino server. The project was formed out of the experience with ProjectCastle, which continues as Project OrangeBox to del

Metawork, nobody is capable but all participate grudgingly
Thu, May 12th 2016 9:41p   Stephan H Wissel
This article is a translation/paraphrase of Professor Gunter Dueck's original post titled DD265: Metawork – keiner kann’s, aber alle machen ärgerlich mit (Mai 2016). Professor Dueck's philosophy resonates with me, so I'd like to make his thoughts available to a wider audience. Bear with my Gerlish. Remarks in brackets aren't part of the original text and are either my comment, extension or explanation. Here we go: Metawork is your own effort to organize work (your's and other's),

Mach Dich auf die Socken!
Mon, May 9th 2016 8:46p   Stephan H Wissel
A common requirement in corporate systems is "let me know when something is going on". In Notes we use "On document creation or update" triggered agents to process such events. To let external systems know about such a change R8 introduced the web service client. This works well in distributed system, but requires quite some work on both ends. In a recent case I had to optimize the communication between Domino and a task running on the same machine. The existing solution was polling the Domi

Annotations to supercharge your vert.x development
Fri, Apr 1st 2016 8:01p   Stephan H Wissel
ProjectCastle is well under way. Part of it, the part talking to Domino, is written in Java8 and vert.x. With some prior experience in node.js development vert.x will look familiar: base on event loop and callbacks, you develop in a very similar way. The big differences: vert.x runs on the JVM8, it is by nature of the JVM multi-threaded, features an event bus and is polyglot - you can develop in a mix of languages: Java, JavaScript, Jython, Groovy etc. This post reflects some of the approaches

Now we are token - Authorization using JSON Web Token in Domino
Wed, Feb 24th 2016 2:37p   Stephan H Wissel
After having Vert.x and Domino co-exist, the door opens for a few interesting applications of the new found capabilites. One sticky point in each application landscape is authentication and authorization. This installment is about authorization. The typical flow: you access a web resource provide some identity mechanism (in the simplest case: username and password) in exchange get some prove of identity that allows you to access protected resources. In Basic authentication you have to provid

The Cloud Awakening
Tue, Feb 23rd 2016 11:31a   Stephan H Wissel
It is a decade since Amazon pioneered cloud as a computing model. Buying ready made applications (SaaS) enabled non-IT people to quickly accquire solutions IT, starved of budget, skills and business focus, couldn't or didn't want to deliver. Products like Salesforce or Dropbox became household brands. But the IT departments got a slice of cloud cake too in form of IaaS. For most IT managers IaaS feels like the extension of their virtualization stragegy, just running in a different data center

Designing a Web Frontend Development Workflow
Fri, Feb 19th 2016 1:50p   Stephan H Wissel
In the the web 'you can do anything' extends to how you develop too. With every possible path open, most developers, me included, lack direction - at least initially. To bring order to the mess I will document considerations and approaches to design a development workflow that makes sense. It will be opinionated, with probably changing opinions along the way. Firstly I will outline design goals, then tools at hand to finally propose a solution approach. Design Goals With the outcome in mind i

Vert.x and Domino
Thu, Feb 18th 2016 6:07a   Stephan H Wissel
A while ago I shared how to use vert.x with a Notes client which ultimately let me put an Angular face on my inbox and inspired the CrossWorlds project. I revisited vert.x which is now 3.2.1 and no longer beta. On a Domino Linux server (I don't have Windows) and on a Mac Notes client the JVM is 64 Bit, which makes the configuration easier (no -w32 switch, no download of an additional JVM). The obligatory HelloWorld verticle ran quite nicely with my manually. However it wouldn't run when the D

Developer or Coder? -Part 1
Fri, Feb 12th 2016 11:42p   Stephan H Wissel
Based on recent article I was asked: "So how would you train a developer, to be a real developer, not just a coder?". Interesting question. Regardless of language or platform (maybe short of COBOL, where you visit retirement homes a lot), each training path has large commonalities. Below I outline a training path for a web developer. I'm quite opinionated about tools and frameworks to use, but wide open about tools to know. The list doesn't represent a recommended sequence, that would be a

Disecting a mail UI
Fri, Feb 12th 2016 1:24p   Stephan H Wissel
At Connect 2016 Jeff announced that there will be an IBM Verse Client for Domino on premises. Domino customers are used to an high amount of flexibility, so the tempation will arise to customize the Verse experience. However this ability is nothing that has been announced in any IBM roadmap. So any considerations are purely theoretical. What is the interface of Verse made of. WIthout reverse engineering, just by looking at it, one could come to the following conclusion: This looks quite mana

The quick and dirty Domino Cloudant export
Thu, Jan 21st 2016 2:45a   Stephan H Wissel
Moving data out of Domino never has been hard with all the APIs available. The challenge always has been: move them where? Ignoring for a second all security considerations, the challenge is to find a target structure that matches the Domino model. Neither flat table storage nor RDBMS fit that very well. A close contender is MongoDB which is used in one compelling Notes retirement offering. However the closest match in concept and structure is Apache CouchDB, not surprisingly due to its heritag

The 3C of leader - leader: Clarity, Competence, Control
Sat, Jan 9th 2016 4:00a   Stephan H Wissel
An organisation failing their objectives has a reflexive reaction: implement more controls. Rumor has it, some sales organisations perform daily cadence calls towards the end of a period to ensure deals close (as if time away from the customer helps). L. David Marquet, in his book "Turn the Ship Around!" paints a different story. Like a plane needs 3 points to be defined, functional organisations need 3C to operate at peak performance: Clarity, Competence & Control. I wrote a short rev

Mess with the Bluemix Colors
Thu, Jan 7th 2016 11:57p   Stephan H Wissel
The Bluemix designers consider their color scheme: robust, decent and unobstrusive. However not everybody likes the dark colors (some do). Stylish to the rescue. It comes in Firefox and Chrome flavours. It requires a custom style sheet and it might take you a while to figure things out. So use this for starters: .dashboardArtifactCreationSection .tile, .cloudOESpaceLabel, .tile-container .tile, .bluemix-global-header, .bluemix-global-header .bluemix-nav-list, .NavTree2, .cloudOEActionBa

Mail archive with Apache CouchDB / IBM Cloudant - Part 1
Wed, Dec 23rd 2015 11:42p   Stephan H Wissel
Like it or not, your eMail turned into the archive of your (working) past. One of the challenges with this archive is the tendency to switch eMail systems from time to time. IBM Notes won't open your Outlook PSD file, nor would Outlook open your Notes NSF database. So a vendor and format neutral solution is required. The obvious choice here is MIME, which is for one, the format any message crossing the internet is encoded in, secondly all eMail applications support MIME - to some extend. Just

Automated Tests in Bluemix Build and Deploy
Wed, Nov 25th 2015 9:43p   Stephan H Wissel
Bluemix is a beautiful environment for agile software development. It's build and deploy capability ensure continious delivery, so you can focus on code. A well run project requires automatic testing (starting with unit tests up to integration testing). You can configure this in the Build and Deploy pipeline, so your project looks like this: While you could argue: "I run my tests local", you might encounter the situation where you use the online editor and you then depend on the tests run

It's just HTML, CSS and JavaScript isn't it?
Fri, Nov 13th 2015 11:48a   Stephan H Wissel
Web development is easy isn't it? After all it is just the open standards of HTML, CSS and JavaScript. That's roughly the same fallacy as to say: It's easy to write a great novel, since it is just words and grammar. The simple reason: It is hard. I'll outline my very opinonate version of what skills you need for mastery of front-end programming. The list doesn't include the skills to figure out what to program, just how. So here it goes: Introduction Jeffry Veen, who'm I had the pleasu

Multitenancy - a blast from the past?
Tue, Nov 3rd 2015 12:36p   Stephan H Wissel
Wikipedia defines multitenancy as: "Software Multitenancy refers to a software architecture in which a single instance of a software runs on a server and serves multiple tenants ... Multitenancy contrasts with multi-instance architectures, where separate software instances operate on behalf of different tenants " Looking at contemporary architectures like Docker, OpenStack, Bluemix, AWS or Azure, I can't see any actual payloads being multi-tenant. Applications by large run single tenant. Th

The lowdown on Notes application web and mobile enablement
Tue, Nov 3rd 2015 10:00a   Stephan H Wissel
There are millions (if not billions) of lines of code written for the Notes client in small, large, simple, complex, epidermal and business critical applications. With the rise of browsers, tablets and mobile devices there is a need to web and mobile enable these applications, not at least since IBM won't let the C code of the Notes client run on iOS (which it could). Whether we like it or not, that body of code can be considered technical debt.   The strategy I see is mostly the same: classi

Domino, Extlib, GRUNT, JSON and Yeoman
Thu, Oct 29th 2015 10:08p   Stephan H Wissel
Contemporary web development workflows separate front-end and back-end through a JSON API and HTTP. There are distinct tools for front-end development, that treat the webserver as source of static files and JSON data being shuffled back and forth. This article describes how my development setup makes all this work with Domino and Domino designer. The front-end tools I use are: Node.js: a JavaScript runtime based on Google's V8 engine. It provides all runtime for all the other tools Bower: a d
