Zopache Technology

Zopache is built on Persistent Python. ‚Äč     History is stored for a day.   If you make a mistake, it is easy to revert to a previous version.  Looks good with Bootstrap.   User navigation is great with Breadcrumbs and every page says which class and view are being looked at. There is also a ZMI and Acquisition.  All implemented on top of a modern Grok/ZTK/ZODB infrastructure. 

Learn Jade: Port your Resume

A meaningful way to learn Jade is to port your resume to Jade.  Start by learning the Jade basics. Use the HTML-to-Jade converter to do most of the work.  Then do the interesting stuff. Use jade includes to include a single element, maybe different introductions depending on the URL.  Use Jade Extends to make a whole suite of changes.  You might have a short version of your resume, and a long version of your resume.  The short one is quick to read, the long one has all the gory details.  They both share the same layout.  And of course it is easy to do multi-lingual resumes. Use JSON to bring in dynamically changing data, maybe your availability date.  

Zopache makes it trivial to manage a family of resumes. In a spam-flooded world, the average human resources person allocates 8 seconds to scan your resume.  If the introduction does not have the right buzz words, she hits the delete button.   To get their attention, you need a family of resumes.   They should have different introductions. They may have different job descriptions.  They may be in different languages.  They should leverage Javascript.   Zopache makes it trivial to manage such a family of resumes.  PrivaCV.com makes it possible to only show the resume you want to the hiring manager.

To manage multiple resumes, you create a tree of folders.  Each folder has its own URL. In the root folder you place your basic resume template and possibly the default introduction and job descriptions.  The basic resume template imports the relevant content. The branches below that are for different markets. Maybe one for SQLAlchemy, one for Django, and one for Ember.   Each market folder has a different introduction.    The branches below that might be for different jobs, maybe you emphasize different parts of your work history..  When a browser accesses a folder, it uses the local content, and acquires the other content from parent folders. So when accessing the Django market folder,   it acquires the basic resume template from the root folder, which imports the local Django introduction.   For a particular customer, you might have a local local job description, but acquire the introduction from a parent, and acquire the resume template from the root.  Once you understand acquisition,  this makes it really easy to maintain a family of resumes.  

Advanced Web Objects

Advanced Web Objects make it easier to build custom web sites. Jade simplifies HTML creation. Markup generates properly formatted HTML document files from a human editable input format. Less simplifies CSS creation. Coffeescript simplifies writing Javascript. Image enables configuring image displays, it calculates the dimensions, and allows one to edit the CSS values: float, border, and margin properties.


Zopache is the only secure browser-based Javascript development environment.  It was used to build PrivaCV.com which enables users to control who has access to their professional information. 

Here is the list of competing products.  Let me know if I missed any. 



Zopache is being used interally as a secure browser-based Javascript development environment.  It was used to build PrivaCV.com which enables users to control who has access to their professional information.  To build an applicatin, you edit a tree of HTML, Image, CSS, Javascript, and other more advanced objects. Every object has its own url. Authorized users can view, manage and edit the objects.   You control authorization.  

There are many browser-based web development environments.  THey let you build static html sties.  There are many content management systems, where you can contribute content, and can control who has access to that content.  There are a few Javascript development environemnts, all but two, require unix skills.  And only Zopache allows you to build a website where you control who has access to javascript-based web pages.  

Zopache.com is my blog about Zopache, Grok, Zope, ZODB and Python. It is written in Zopache, and organized as a subject tree.

Use the expandable tree on the left to find the topic of interest to you.

Here is some additional information.  You can skip it. 

Multilingual Editor/Server

Zopache is also the only multilingual html editor/server I know.  Usually multi-lingual people have to maintain two separate web pages, one in each language.  What a pain.  With Zopache, you edit a single web page, the last two letters of the url determine the language displayed.  Resume/en would be in English.  Resume/es would be in Spanish.  Technically the view on the resume sets the language headers, and javascript sets the CSS to determine which language to display. 


Single Page Web Platoform

Here I review different options for single page web platforms. 


In the zope world, there are many topics that cut across different products. Such subjects are documented in this section.

Zopache Computational Model

Zopache is not just a bunch of TTW objects. It is a different computational model than either Zope2, or Grok/ZTK. All three support a ZODB tree of persistent objects with child references. Grok, ZTK and Zopache also have parent references. Unlike Zope 2 TTW, Zopache TTW allows references to remote branches of the tree, making Zopache TTW into a graph database. Unlike ZTK/Grok, Zopache hides both python namespaces, and the Zope Component Architecture from beginners, making them available to advanced developers.


Zope is very interesting. Both hugely promising and hugely difficult. Grok makes it easy to use. Zopache makes it trivial to use. But it still suffers from too much complexity. In particular registering widgets was a terrible idea. More on this in the section on Forms.

I invite you to Register and then link to your own blog postings and software packages..
