Django book and Real World Haskell are using some similarly-looking web publishing platforms (with rigid TOC/chapters/paragraphs+comments structure). However, I haven't found any reference to the platform used on the corresponding websites. Is there a publishing framework or CMS similar to the ones mentioned?
This question about the availability of Djangobook's code may help.

I am building a XCFramework for my company and the primary purpose is to expose our data for clients using this Framework. Clients can access data using this Framework through use-cases without knowing the implementation details.
This Framework needs a very high run-time maintenance support as we may have to add or update the use-cases based on clients requests or changing busing requirements. It's very important to design an automated solution to deploy new changes and make the updated Framework available for clients. I'm looking to host SDK somewhere so I can build and deploy it. Something like maven for Android. But I've not found some good solution yet.
I would love to hear if someone has similar experience or if someone can guide for a better solution. Thanks
I am developing a website for a small business in Spain with Java, Bootstrap, jQuery and I need to integrate an ecommerce platform
Is Snipcart the best option or do you recommend any of the similar solutions that for some reason you will agree is better?
Thank you
Disclaimer: I work for Snipcart
The advantage of Snipcart over other solutions is that it's independent of your other stack choices. You can select your backend tech based on what you're the most comfortable with.
If Java, Bootstrap and jQuery are requirements for the project, Snipcart won't get in the way of those. That's one of the big selling points, it can provide a lot of features for platforms that don't have a feature-full ecommerce framework.
I wouldn't know which Java-based ecommerce platform to recommend and compare to. There seems to be a few but none with big market shares or recognized name.
If Java isn't a strong requirement of the project, I'd look into PHP and Ruby/Rails solutions as they have more mature ecommerce solutions.
I am trying to develop an ASP.net MVC website in which I need to show a map (whole world) with several markers and additional information for every marker.
Does anyone know a good library that would support that and which (if possible) also lets me use "offline" maps stored on my own server (open street maps for example).
It will be an intranet application which means in case of google/bing yearly license costs would have to be paid. The customer doesn't want that, but in general the library can be commercial (one-time per server and/or developer fee).
I already had a look at "ThinkGeo Map Suite", any other suggestions or recommendations.
SharpMap, it's flexible and easy to implement, can use with shapes or from spacial db.
for details... http://sharpmap.codeplex.com/
there is a couple examples who does exactly what you need, so can start from these
exist other libraries but I don't try it, research for another options.
Answer
Manifold is a very cheap system which has an basic internet map server framework:

You already suggested ThinkGeo, I would put it in the same basket as Manifold. Be sure to evaluate performance and limitations with both packages.

You'd be hard pressed to find a pure NET library for mapping that works well and won't blow out your budget (see ESRI). Depending on your skill level and your knowledge of GIS systems, I would suggest creating your own web map server and just embed it in your web application.
Some good environments for this which I can recommend are:
MapServer
GeoServer
As far as displaying and interacting with the map, there are several web based platforms available:

Now that Google allows Java on App Engine, I'm wondering what effect this has on a choice of web framework for App Engine.
I realize Google provides the webapp
framework which is pretty barebones.
And the .96 version of django that's
available for App Engine is
restrictive.
web2py burns up resources, from what I've heard.
Rails (now available) can't use
ActiveRecord, ActiveResource,
restclient, rmagick.
Is there something I'm missing - do any frameworks work well on App Engine?
Actually web2py is very light and since ~1.50 on GAE, it caches all bytecode compiled models/views/controllers.
Nevertheless you need to consider that by default is has datastore based sessions and this may add some overhead when compared with framework that do not have sessions working on GAE (at least not by default).
The web2py DAL itself does not add a significant overhead when compared to the naive Google datastore APIs.
Personally, I have found Python to be more fun. That's just me. However there are several commited Java developers out there that will appreciate the Java support in GAE. Furthermore, supporting Java was a good choice by Google since it will allow the GAE platform to potentially host many other languages. It's obviously a little early to expect all JVM based languages to run on GAE, but the future looks promising. For now we can look at what is and isn't working by taking a look at this GAE Java Group Page.
Coming back to Python, I think small web applications will work great with the built-in webapp framework. Other applications will benefit more from Django 1.0. Have a look at the GAE articles under the frameworks section for a few good reads on this. In any case, you will undoubtedly have restrictions in any of your choices since most web frameworks are designed with relational databases in mind ... which datastore/bigtable is not. Furthermore, the GAE platform has to be sandboxed for security reasons which also restrict you to some extent. Hope this helps.
Try Spring. It supports JPA and JDO.
There's even a Python version for Spring now.
I don't know exactly the full range of options, but I can tell you a couple of things off the bat...
Google Apps is built on top of / using Django.
Django is pretty much what Google Apps cheer and support, so I'd expect it to integrate with Google Apps better than others.
Google Apps has restrictions built into it that you cannot circumvent (or shouldn't). These limitations are not related to any particular framework, rather they are built into the fabric of Apps, so to speak.
I wouldn't worry much about performance of the framework - try to improve your design/structure, it will certainly payback better.
Google will eventually move to Django 1.0 and newer, plus they are updating Google Apps too.
They do use memcache (or an equivalent) so take that into consideration and utilize it.
It really depends on what you want to do. In my experience something small hand made on top of Webob is really good for an API. But for full fledged sites that need templates/sessions/complex routing/caching django is hard to beat.
Take into account that if you huge frameworks (like django 1.0) the first request always takes around 3 seconds to load everything in memory and keeps it there until 15 secs after that request.
And while you shop around for frameworks take into account that:
ORM's don't apply to the platform so basically don't matter.
Fast templates (like Cheetah) won't be fast (or even work) as they can't use c extensions.
Caching might be the most important thing to make everything fast.
If you are looking for Python, then Django would be your best bet.
Struts 2 is purported to work on Google App Engine (at least in terms of the example applications). Follow this thread:
http://www.nabble.com/Google-App-Engine-support--td22972179.html
It appears that there are some issues with Sitemesh in terms of templating, but if you're using JSP you should be ok.
It's a good choice as a web application framework goes.
I recommend web.py if you're using Python.
I use new framework GAE framework. This is similar with Django, but work on AppEngine.
Best regards!
For Python use webapp2 (comes bundled with app engine)
If you want to build large scale application and need more flexible framework, then you can take a look at Pyramid Python Framework. Previously it is called as Pylons. There are lot of good companies using this framework.
What tools are available for metamodelling?
Especially for developing diagram editors, at the moment trying out Eclipse GMF
Wondering what other options are out there?
Any comparison available?
Your question is simply too broad for a single answer - due to many aspects.
First, meta-modelling is not a set term, but rather a very fuzzy thing, including modelling models of models and reaching out to terms like MDA.
Second, there are numerous options to developing diagram editors - going the Eclipse way is surely a nice option.
To get you at least started in the Eclipse department:
have a look at MOF, that is architecture for "meta-modelling" from the OMG (the guys, that maintain UML)
from there approach EMOF, a sub set which is supported by the Eclipse Modelling Framework in the incarnation of Ecore.
building something on top of GMF might be indeed a good idea, because that's the way existing diagram editors for the Eclipse platform take (e.g. Omondo's EclipseUML)
there are a lot of tools existing in the Eclipse environment, that can utilize Ecore - I simply hope, that GMF builts on top of Ecore itself.
Dia has an API for this - I was able to fairly trivially frig their UML editor into a basic ER modelling tool by changing the arrow styles. With a DB reversengineering tool I found in sourceforge (took the schema and spat out dia files) you could use this to document databases. While what I did was fairly trivial, the API was quite straightforward and it didn't take me that long to work out how to make the change.
If you're of a mind to try out Smalltalk There used to be a Smalltalk meta-case framework called DOME which does this sort of thing. If you download VisualWorks, DOME is one of the contributed packages.
GMF is a nice example. At the core of this sits EMF/Ecore, like computerkram sais. Ecore is also used for the base of Eclipse's UML2 . The prestige use case and proof of concept for GMF is certainly UML2 Tools.
Although generally a UML tool, I would look at StarUML. It supports additional modules beyond what are already built in. If it doesn't have what you need built in or as a module, I supposed you could make your own, but I don't know how difficult that is.
Meta-modeling is mostly done in Smalltalk.
You might want to take a look at MOOSE (http://moose.unibe.ch). There are a lot of tools being developed for program understanding. Most are Smalltalk based. There is also some java and c++ work.
Two of the most impressive tools are CodeCity and Mondrian. CodeCity can visualize code development over time, Mondrian provides scriptable visualization technology.
And of course there is the classic HotDraw, which is also available in java.
For web development there is also Magritte, providing meta-descriptions for Seaside.
I would strongly recommend you look into DSM (Domain Specific Modeling) as a general topic, meta-modeling is directly related. There are eclipse based tools like GMF that currently require java coding, but integrate nicely with other eclipse tools and UML. However there are two other classes out there.
MetaCase which I will call a pure DSM tool as it focuses on allowing a developer/modeler with out nearly as much coding create a usable graphical model. Additionally it can be easily deployed for others to use. GMF and Microsoft's Beta software factory/DSM tool fall into this category.
Pure Meta-modeling tools which are not intended for DSM tooling, code generation, and the like. I do not follow these tools as closely as I am interested in applications that generate tooling for SMEs, Domain Experts, and others to use and contribute value to an active project not modeling for models sake, or just documentation and theory.
If you want to learn more about number 1, the tooling applications for DSMs/Meta-modeling, then check out my post "DSMForum.org great resources, worth a look." or just navigate directly to the DSMForum.org
In case you are interested in something that is related to modelling and not generation of code, have a look at adoxx.org. As a metamodelling platform it does provide functionalities and mechanisms to quickly develop your own DSL and allows you to focus on the models needs (business requirements, conceptual level design/specification). There is an active community from academia and practice involved developing prototypical as well as commercial application based on the platform. Could be interesting ...
