I have an element for my side bar navigation being called from my layouts/default.ctp file, I need to access some data about categories from my Photos controller. How would I go about doing this?
Using JNI can we pass custom data types from Java to C (or vice versa)? I see a mapping of primitive datatypes to types in C however not too sure if we can send across our own data types (e.g. Send across or return an Employee object or something!).
We use cell.getContents to read the values of a cell, the content contains data (e.g. 10.2327), the data gets read as "10.233". Not sure why we are unable to read the string as it is
In the field of Data Mining, is there a specific sub-discipline called 'Similarity'? If yes, what does it deal with. Any examples, links, references will be helpful.
Also, being new to the field, I would like the community opinion on how closely related Data Mining and Artificial Intelligence are. Are they synonyms, is one the subset of the other?
Thanks in advance for sharing your knowledge.
Hello,
i am working with APE Engine (http://www.ape-project.org) and up until now i had no actual problem.
The problem is that i would like to use the MySQL module and push data to a channel each time a row is inserted into a table.
I've tried to setup a server side module, i created an SQL query but data is fetched only when the server boots.
How can i make this work?
I have a windows application in which a form is binded with the data.
The form loads slowly because of large data. I am also showing paging in form to navigate through the records.
How to increase the performance?
How can I plot (a 3D plot) a matrix in Gnuplot having such data structure. I cannot find a way to use the first row and column as a x and y ticks (or to ignore them)

2,-6.39,-6.52,-6.31,-6.00
3,-6.36,-6.48,-6.15,-5.90

Is the splot 'data.csv' matrix the correct parameter to use ?
I have event data displaying on a map and I am currently using the geo microformat alongside it however it's not particularly rich to have just a list of locations without any details of what they correspond to.
I've been looking at combining microformats to achieve this and looking for some thoughts on the subject
here is the data i am marking up:
event title, event location [latlong], event address, contact phone, link to full details
My initial thoughts are to use an hCard along with geo? Is there anything better?
Thanks in advance

Hello All:
I am using entity framework 3.5 for my application.
I want load data based on some condition e.g.
var data = from e in context.Employee.Include("Employee.Projects") where e.IsActive select e;
Using this, I will get all the Employees which are active with their project details. But I want to load only those projects which are active. So, how to load only active projects using the query?
Thanks

I have an Excel Spreadsheet that contains all my data that I need to put into an SQL Server database. I am fairly new o ASP.NET and have never had to export from Excel to SQL Server before.
My Excel spreadsheets looks like this
Trade Heading - ArtID - BusinessName - AdStyleCode - Address - Suburb
In SQL Server I have created a table named "Listings" which is in this format
intListingID - intCategoryID - BusinessName - ArtID - intAdCode -Address - Suburb
What would be the best way to export the data from Excel and then import it into SQLServer 2005.
Thanks...
If there a way to protect against concurrent modifications of the same data base entry by two or more users?
It would be acceptable to show an error message to the user performing the second commit/save operation, but data should not be silently overwritten.
I think locking the entry is not an option, as a user might use the "Back" button or simply close his browser, leaving the lock for ever.

What approach is considered to be the best to store and manage video files? As databases are used for small textual data, are databases good enough to handle huge amounts of video/audio data? Are databases, the formidable solution?
Apart from size of hard disk space required for centrally managing video/audio/image content, what are the requirements of hosting such a server?
This is really just a conceptual question for me at this point.
In Lisp, programs are data and data are programs. The REPL does exactly that - reads and then evaluates.
So how does one go about getting input from the user in a secure way? Obviously it's possible - I mean viaweb - now Yahoo!Stores is pretty secure, so how is it done?
Quick question, my data model is a singleton object and it contains a list of names I want archive. My idea is to make the model responsible for loading / saving this data. The ModelLoad will then be called by the ViewControllerviewDidLoad and the ModelSave by ViewControllerapplicationWillTerminate. I could do the load / save directly within the ViewController, but this would be messy as the list of names are on instance variable of the model.

When I read a sheet into a DataTable using the OleDbDataReader, floating point numbers loose their precision.
I tried forcing OleDb to read the excel data as string, but although the data is now contained in a DataRow with each Column defined as System.String it looses precision (18.125 - 18.124962832).
Any idea how to avoid this behaviour?
hi--
my goal is to send an NSView over the wire. i was wondering whether there was a way to get the raw display data contained in an NSView so that I can send this data over the wire and re-display this at the destination.
thanks.
I read an article around schema-less database which sounds cool. (http://bret.appspot.com/entry/how-friendfeed-uses-mysql)
But what isn't clear to me is how do they run search queries on this data? Since the data is in JSON format how do we look for it?
Has anyone written a YQL open data table for accessing Wikipedia? I've had a hunt around the internet and found mention of people using YQL for extracting various bits of information from Wikipedia pages such as microformats, links or content but I haven't been able to find an open data table that ties it all together.

I've noticed with Xcode 3.2.2 that all the custom data formatters are no longer working. Some searching around the mailing lists and google confirms others are having the same issue.
A) Anyone else seen this
B) Got a work around or an example custom data formatter plugin that still works in 3.2.2 that I can look to for hints on how to fix the ones I have?
