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://foo@host.org. 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 10.10.10.10 is the HTTP proxy host and 8080 the http proxy port. Host host.org ProxyCommand corkscrew 10.10.10.10 8080 %h %p That was all, I setup my SSH key and could connect.

Fridaygram 03/2015

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: http://thecodinglove.com/post/102017524268/friday-at-6pm

My Week in Links [GER] JAXenter.de hat eine gute Artikelsammlung zum Thema Docker bereitgestellt. [GER] In sieben Schritten ins Internet der Dinge IMHO a very good and actual  Overview about Industry 4.0 ScrumMasters Should Not Also Be Product Owners. Period. I like this Portfolio Board from Ship It! Go and copy! We have visualized our portfolio in a not so illustrated way and its worth it! Send a JSON object to server over TCP connection in Java using Socket yes, simple stupid java stuff. If you want to move from local Hadoop development to a remote, real life cluster, start and finish in 20 minutes (or so ;) ): Setting up a CDH cluster on Amazon EC2 in less than 20 minutes  Have a nice weekend!

My week in Links: Martin Fowler added an useful discussion on his bliki about the TechnicalDebtQuadrant I found the Missing Guide of How to Use Docker on OS X I tried to understand and play with Hadoop.

Fridaygram – Das Freitag-Update

Und da bin ich mal wieder. Ich habe mir überlegt, dass ich Freitags eine kleine Liste von Artikeln aus dem Bereichen Agile Softwareentwicklung, Continuous Delivery, oder generell mit IT Bezug publiziere, die ich in der jeweiligen Woche entdeckt und für empfehlenswert befunden habe. In dieser Woche sind auch noch ältere Sachen dabei, die ich beim aufräumen in meinem Instagram Account gefunden habe. Agile Softwareentwicklung: Scaling Scrum: SaFE, DAD or Less bewertet die genannten drei Vorgehensmodelle. Agile 42 Mitarbeiter Andrea Tomasini hat seine Anatomy on an Agile Organization des Manage Agile Keynote publiziert (Quelle). Noch mal Agile 42 mit The Product Owner (PO) Board – making PO workflow visible. Als Freund von physischen Tokens gefällt mir die Herangehensweise. Interessant wird es mit mehr als einem Team und mehr als einer Vision. Martin Fowler über das Thema Messbarkeit von Produktivität. Continuous Delivery Kief Morris hat bei Martin Folwer einen Bliki-Eintrag zum Thema Configuration…
