I am modelling a personnel rostering based on Drools Planner Nurse Rostering.
I am toying with the *.xml samples based on the competition.xsd schema.
The schema is in general very clear, but there are so many configuration parameters that I am not sure how to properly configure each of them. For instance, I cannot figure out how to correctly set up the patterns and their usage in the contracts tags.
The aim is to correctly model my scenario .xml file in order to avoid unnecessary contraints and to correctly weight the useful ones.
So, I am looking for some detailed references about the competition.xsd schema, and maybe a tutorial about the usage of the schema.
Nurse rostering competition documentation found here.
A usefull article by Geoffrey De Smet here.

I understand that Chisel is a HDL/HCL language to overcome some of Verilog/SystemVerilog restrictions by using higher abstraction level.
And it is open source as well.
It might be a bit naive and presumptuous, but still I would like to ask.
My question is that why do so many similar efforts are working in parallel, e.g. Blusspec, spinalHDL, Pyha etc?
I mean, is there any reason why the development community may not choose one of these and concentrate efforts on stabilizing or enhancing one of these.
That's exactly what is happening now, it just takes a while to choose.
Although the past does not show that the best technology wins, let us hope it does this time.

I want to create a new rails application and I'm not sure whether to use MySQL or Postgres. Which one is best and what is the difference between them?
UPDATE:
The project is a health-care project. It may contain more than 500 tables.
postgres is secure, fast, and full of features but comparatively tricky to use.
MySql has its own benefits along with large user community and vast materials. Immensely helpful if you ever get stuck.
But ultimately it all comes to your preference and framework (apart from rails if your app requires any) support.

I'm writing documentation for my AQA A-level Computing project. The project is a game which takes place in a Console application, which heavily depends on a series of classes and structures in a separate class library I have written. I don't know how to title the section in my documentation where I describe these classes and structures, and I'd like to know if there is a word that encompasses both concepts. Does the word "record" include both classes and structures, or is it tied to a specific implementation?
I'm aware that this is more English Language & Usage, but I thought it was more likely to get a response here where there are more programmers.
Yes, you could use the term record as objects/classes/structures are just differing types of records, or records with functions to handle the data in the record.
However, just to encapsulate all your possibilities, you should probably utilize the term Data Structure. I find that data structure is more common parlance than record.

I've been developing a small database for my summer internship and I need to write a manual/documentation for it aimed at both users and developers for future use. Thing is...I have no idea where to start or what information to include. Many people I work with have no idea what databases can do so I need to keep it as simple as possible. The database is implemented in Access and I experimented with the database documenter but I think that is overkill. Is there some kind of documentation standard that I can follow or anything of that nature?
As a starter for ten, I'd have thought that the user documentation should be task orientated.
(i.e: How to achieve 'X'.)
In terms of the developer documentation, defining the meaning of any non-obvious fields in your schemas, how they're used and the relationships between different tables, etc. would be a good start. (I'm presuming your VBA code is well commented, etc.) You may also want to examine the existing "Documenting Visual Basic with Doxygen" question/answer.
Just straightforward english if you are explaining a process.
If you have a series of Macros do a document highlighting to code used in each macro and the order it should be employed. This could aid someone down the line if they are trying to automate the process.

Upon reading a blog post about a minimalist story-generating python program, I was asking myself - and you - which are the most successful attempts at such programs. I remember seeing something using generating grammars, for instance. And which are the best attempts that, like this one, are extremely compact, either self-contained or able to read, say, the Web or an independent textual corpus (but not simply a file with a large number of story chunks)?
Search for Talespin for some famous ground breaking work. (Example: Micro-Talespin in Common Lisp by Warren Sack.)
I actually like Turner's "Minstrel: A Computer Model of Creativity and Storytelling" better :
ftp://ftp.cs.ucla.edu/tech-report/1992-reports/920057.pdf
Talespin is, in my opinion, blind in it's algorithm to everything but planning. So the author goals are given very little consideration (if at all). Minstrel is better that way.
