Retrospective January 2016

Favorite slogan: You want to get things done, not building an inventory of unfinished work!

What have I done:

  • Kicked of the first quarter 2016 with hard deadlines for Cloud of Things (watch out for CeBIT)
  • Had some weekend & night shifts because of service outages of Cloud of Things. Turned out that a Gelf4J appender for Graylog caused the issues.
  • Started to play with JavaFX and build a Cloud of Things Genius Client for testing purposes on CoT. (Thanks code.makery for this helpful JavaFX tutorial)
  • Did a talk on our Deutsche Telekom M2M Day 2016
  • I have a new record on contributing to Github



PS: A new try to give a regular update on this blog. Last year I tried a weekly recap, didn’t worked out. But I’m pretty sure that this will work ;-)

Internet of Things – my thoughts revisted

I had written my first article about my thoughts on the internet of things about three months ago. I gained some more insights and experiences since then, also, for the beginning of 2016 I feel the time has come for an update.

In my last post I wrote about the maturity of IoT solutions. I think the market is still in the same position. There are many innovators, doing their first steps by digitalizing things and connect them with the Internet (by the end of 2016, do we still talk about the Internet of Things? Or just the Internet?). But the main issue is still the variety of technologies, the problems of physical implementations in retrofit, different types of use cases. Okay, I would make an exception for the Smart Home industry. These points are huge barriers for the implementers in terms of time, budget and quality (ROI).But all the machine manufactures, the producers of all the physical things which doesn’t need a power supply? The big tech companies (e.g. Amazon and Microsoft) are developing tools and services for the market, but they don’t address a major problem: the mass-market digitalization and connection of things.

Hotwo get an OpenShift custom HA Proxy router

I’m testing RedHats new version of their PaaS product OpenShift 3.0. I would like to find out, what capabilities are there for using different protocols than http and http+tls, because it was a missing feature in the 2.0 version. OpenShift 3.0 has the concept of routers to direct incoming traffic to the endpoints. Sad but true fact is, there are just two implementations of routers available (HA Proxy andF5 BIG-IP®) and they just support the protocols HTTP, HTTPS (with SNI), WebSockets and TLS with SNI. Nevertheless, there are some fancy HA Proxy configs for other protocols and I want to play with them. First of all I needed to get a custom HA Proxy running. Here is how:

Internet of Things – My thoughts on IoT

This week I read an article on Wired about the data flow in the Internet of Things. It is essentially about how things are connected and where the data flows through, and provides a good description of the basics of Internet of Things. But connecting machines, devices and other things, and transferring data from one site to the other is just the necessary stuff. Don’t get me wrong – it is pretty complex, perhaps even the most complex part of it. The heterogeneous physical interfaces, protocols, connectivity options and use cases result in maximum diversity on this site. However, with a good range of IoT software systems we can solve any problem. By the way, it is wise to choose an independent IoT system regarding devices and technology. This will assure your investment for the future. Sad but true – the amount of work for integration still does not fit all business…

It was very quite here since a while. This was manly caused by the heavy workload I had, to bring up our service Deutsche Telekom M2M Device Cloud (or Cloud der Dinge for German market). It is the starting point of Deutsche Telekom IoT solutions, a device management and IoT app-enabling service. Find more information about it on our website – which btw needs an overhaul, but you get the main point: Device Cloud. For German readers also interesting about the Telekom Industry 4.0 package. Of course, talking about the topic IoT, we mix up different buzz words, following the newest marketing wagon. M2M, Internet of Things, maybe Industry 4.0 is a little bit special because it covers more than IT. But roughly it becomes all the Internet again, as you follow this O’Reilly discussion. This is also my understanding. So, this week we started operation of our service. Not…

Setup Windows SSH to connect via Proxy to Host

I had the problem to connect to a SSH Host through a HTTP Proxy. I could run it with Putty, just entering the host and port in the proxy configuration section. Fine so far, but I want to clone GIT repositories from this host, git clone ssh:// So Putty was out (maybe I could tunnel…). So I used this solution: Install basic Cygwin Install packages openssh, git and corkscrew Setup  ~/.ssh/config (where is the HTTP proxy host and 8080 the http proxy port.

That was all, I setup my SSH key and could connect.

This is my week in links: maybe I should rename it from fridaygram to something weekly VentureBeat about what to expect next: A cloud platform for the Internet of things. (Can’t wait to launch our work) [GER] German language, but very good article about why a process model (1st level) is the wrong way to use scrum in large projects. It is about more about self-management and self-organisation. Die Skalierung von Scrum ist doch gar nicht das Thema! (Maybe use translated version) A Beginner’s Guide to Understanding the Internet of Things Some DevOps stuff from Deutsche Telekom for automatically hardening your server system. It starts with support for Linux OS and some applications MySQL, PostgreSQL, Apache and Nginx Just found the UX und Tollerei Blog. Maybe a good UX resource for you: Read the latest issue Learning to Wireframe: 10 Best Practices. A help for every Product Owner or Product…

Fridaygram 51/14

Two Fridays without links in the box in a row. This is due to an increase of workload in this last weeks in the year. It was hard but fun and we had a lot of success. I go all tingly about what happens in the next year. So, at least one link for fun Friday:
