Don't use "docker" in Github repo names or as Twitter handles

The strict trademark guidelines of Docker Inc. can easily be turned into a case against any open-source programmer or project using "docker" as a repository name or for example as a Twitter handle. Act now!

The trademark guidlines of Docker Inc. for protecting the trademarks are dangerous and harmful to the open-source community around Docker.

In particular you are not allowed to use 

  • repository names for your open-source projects starting with 'docker'
  • use 'docker' as part of a Twitter names like @dockersucks, @dockerfan or @docker-usergroup-nyc
  • ....

I asked Docker Inc. about using 'docker-' as part of some of my repository projects on Github.

So here is there answer:

So what does this mean?

You are subject to be contacted the Docker Inc. for renaming or removing your project.

In the worst case Docker Inc. can sue you.

To make it clear: every company has a right to defend the trademarks and copyrights - no exception.

However a company like Docker Inc. that is driven and backed by a huge open-source community has certain obligations regarding the fair-use of trademarks by the community.

The current Docker trademark policy is an asshole policy:

Brought to the point: We are Docker Inc, we are the kings. You (the community)....we don't care about you. 

How can Docker Inc. get out of this problem:

  • relax the policy for open-source project regarding repository names, social media names etc. for open-source usage of Docker technology
  • allow the usage of 'docker' in domain names for open-source in general e.g. for usergroups etc. (any person should be allowed to ask 'docker' as part of domain name for non-commercial purposes).

We had the same discussions with Zope Corporation 15 years ago regarding trademarks etc. around the term ZopeIn the end Zope Corporation moved most of the copyrights and trademarks into the Zope Foundation and established a fair-use policy that worked for the years. The same is true for other entities holding copyrights and trademarks like the Plone project with its legal entity the Plone Foundation

Copyright and trademarks vs. open-source community is not a contradiction. The last decade and longer showed that there is reasonable way to deal with commercial interests side by side with community interests.

So Docker Inc play nice and fair with the people that made you what you are.

Clarification: Docker Inc. did not ask me to take down or rename my repositories. As you can see from the screenshot I asked Docker Inc for a clarification on this issue and the answer is shown above.

Stellungnahme der Antidiskriminierungsstelle des Bundes zur Beförderung von großen Personen bei Airlines

In einer formlosen Anfrage an die Antidiskriminierungsstelle des Bundes habe ich gefragt, ob es das Zusammenpferchen von großen Personen wie mich (203cm) in der Economy Klasse der meisten Airlines auf dem Platz einer Legehenne rechtlich vereinbar ist und ob sich aus der Körpergrösse ein Anrecht auf eine menschenwürdige Beförderung ableiten lässt. Die Antidiskriminierungsstelle antwortet mit einer interessanten Rechtseinschätzung....


Cross-browser hyphenation support for Plone 5

Most browsers lack hyphenation support (except Firefox). This Plone 5 add-on brings customizable hyphenation support to Plone 5 e.g. for better readability of the Plone 5 toolbar in German language.

Browsers - even in 2016 - are in general bad when it comes to hyphenation using CSS. CSS provides support for hyphenation for a long-time through hyphens: auto. However most browser excepts Firefox do not support hyphenation of text. There are some Javascript add-ons around for providing  hyphenation support across all browsers and most common languages - solutions like Hyphenator.

In general hyphenation on the web is not that important as hyphenation in print due to different display sizes, responsive design etc. However in some situations you want proper hyphenation for words or texts when the horizontal width of a box is limited and the standard word breaking algorithms of browser just generate a bad result.

This is one of (my) issues with the Plone 5 toolbar which looks like this (out-of-the-box with German as language) with completely unacceptable and improper word breaks.

zopyx.plone.hyphenator solves this problem by integrating Hyphenator with Plone 5. 

As a result the Plone 5 toolbar looks much nicer - in particular because a proper hyphenation. 

zopyx.plone.hyphenator can be configured to apply hyphenation to arbitrary page element by specifying a list of related CSS selectors within the Hyphenator control panel

Hyphenator supports most of the frequently used languages. Further hyphenation options provided by Hyphenator  will be supported by zopyx.plone.hyphenator  over time.



Plone 5 and XML-Director 2.0 with Dropbox integration

After many months of pain with Plone 5.0, XML-Director 2.0 will be finally available for production soon. This screencast shows you how to integrated Plone via XML-Director with Dropbox (or other databases or (cloud) storages).


We are looking for some upcoming projects support by a web/frontend developer.

  • MUST speak GERMAN fluently
  • MUST be based in Germany
  • MUST be able to travel within Germany (Hamburg, Berlin, Stuttgart area)

Applicant must be fluent with 

  • Javascript, jQuery and related frameworks

  • CSS
  • tools like SaSS, Less, Bootstrap or related Frameworks

Applicant must be able to able to design decent web user interface.
You should have a reasonable understand of the "mobile first" approach
and some background in building "progressive web apps". You should be familar
with the most decent tools in web/mobile development etc.

In the first phases of the project you will direct interact with the CEO/CTO
for creating initial mockups and UI prototypes .

A big plus would be  experiences with native applications (Android, iOS)
through some frameworks like Phonegap etc. for building hybrid applications
that work both within the browser and for better user experience as native app.
Knowledge in Python would be nice but is not a must however you should be fluent
with Linux, the command line and tools like GIT. Additional skills welcome.

This position is a remote position but being located in Germany (see above) is a big plus.


Please get in touch with Andreas Jung (info@zopyx.com) and include your CV, references, experiences with related frontend and web technologies.

This is a followup to two earlier blog posts [1 2] related to our XML-Director Web-to-Print  approach.

Today we added section that describes some internals - in particular how to write templates and styling.

Plone 5 as foundation for XML Director Web-to-Print solutions (continued)

XML Director is an generic solution for building XML-based content management solutions based on the CMS Plone. This video shows how we build easy-to-use web-to-print applications using CSS Paged Media (XML/HTML for input, CSS for layout and styling). This demo features the PDFreactor PDF converter and the Nimbudocs WYSIWYG editor by RealObjects. Plone 5 as foundation for XML Director Web-to-Print solutions

This is a follow of my blog entry from yesterday.

There is now a demo portal where you can try Plone 5 with the XML-Director based Web-to-Print solution. You can pick up one (out of four templates) and modify selected parts of the documents either using a form or directly within the PDF layout.

Plone 5 as foundation for XML Director Web-to-Print solutions

XML Director is an generic solution for building XML-based content management solutions based on the CMS Plone. This video shows how we build easy-to-use web-to-print applications using CSS Paged Media (XML/HTML for input, CSS for layout and styling). This demo features the PDFreactor PDF converter and the Nimbudocs WYSIWYG editor by RealObjects.

The migration of XML Director to Plone 5 is making big progress. As part of the ongoing effort I extended XML Director as web-to-print solution platform.

The following screencast shows how it is possible to use Plone 5 and XML Director as decent web-to-print application. The screencast shows to usecases:

  1. generation of PDF from a given HTML templates and CSS styles with form data filled through Plone. The input forms for each template are automatically generated from the HTML (with some additional metadata stored within the HTML, no need to create forms manually or individually). The generated PDF file is being stored automatically on the preconfigured storage (XML database, cloud storages, local filesystem).
  2. editing of the template using the Nimbudocs editor. The Nimbudocs Editor provides WYSIWYG editing of the template. The layout looks exactly the same as in the final PDF.
