I need to amend QuerySet data when i return it to a template.
for example, model.objects.all() returns a date (with other fields), but i also want to return the number of days since that date has passed. This is so that in the template, i can say "you last logged in 4 days ago".
What is the best way to do this?
What's the best way to store language data?
Keep it as variables in some kind of lang.php file...
$l_ipsum = 'smth';
$l_rand = 'string';
Or select them from a database? I'm in search of your advice.
I'm using Elmah with ASP.NET and wondering how I would add custom data, such as a session variable, to an unhandled exception email.
I've tried several handlers in the Global.asax file but can't seem to find the right one.

I want to use PHP (possibly with Curl/XPath?) to extract data from Wikipedia pages. What would be the best way to go about this? I'll be using CakePHP for this project, although just need to figure out how to get this working first.
Hi Al,
I have a simple navigation based app which has a bunch fo forms in it, I have a method connected to a button that saves data when the button is tapped but I was wondering if I could call the same method when the back button is tapped in the navigation? Just incase a user fails to use the save button. If it is possible, how would I go about it?
thanks in advance!
While searching for some functions in C++ STL documentation I read that push and pop for priority queues needs constant time.
"Constant (in the priority_queue). Although notice that push_heap operates in logarithmic time."
My question is what kind of data structure is used to mantain a priority queue with O(1) for push and pop ?
How would I go around creating a MYSQL table schema inspecting an Excel(or CSV) file.
Are there any ready Python libraries for the task?
Column headers would be sanitized to column names. Datatype would be estimated based on the contents of the spreadsheet column. When done, data would be loaded to the table.
I have an Excel file of ~200 columns that I want to start normalizing.
I'm fairly new to programming and new to java, but I'd like to jump in the deep end with a little database driven website project. I've read quite a lot about requirements in the 'real world' requesting experience with Spring and Hibernate, so I have those installed on netbeans and a project created (if I hit run I get the default spring page). Now I just need a little guidance as to where to start designing my app (please tell me if I'm getting in a bit too over my head for a beginner!).
Should I start off with my classes? - create all my classes as they map to my database tables and decide which attributes and methods each will require?
Can anyone suggest any good books for maybe.. making a java based website from scratch (i.e. from design right through to deployment) that might be useful for a beginner?
Any help appreciated thanks.
I'v created a Notepad-like application and if I load a 1MB file into the textbox, it takes about 1 minute. The Visual Studio Binary editor displays lines, Hex, and ascii versions in a fraction of a second. How do they get the data into the textbox so quickly?
Thanks
It is often said that using LDAP is a good way to store data about users. That's beacause users' "directory" is hierarchical and it changes rarely. But in my opinion that doesn't exclude using RDBMS. What might be reasons to use LDAP? I guess that storing multi-valued fields or adding custom fields in LDAP might be easier but it can be done in database too (unless you have many records)
Hello,
what can i do, if a Mailserver accepts a connection but does not return any data? The default javax.mail implementation just hangs indefinitley. Event setting the smtp.timeout does not help - it still hangs. I even tried to set a custom SocketFactory to set the sotimeouts and solinger directly, but it still hangs. Somehow the socket does get kept alive? But how?
Thx for any ideas!
Ciao, Nils
Hello,
So far all the Excel stuff revolves around opening a file, writing values to it and saving it.
Is there a way to update the data in the Excel (while it's opened) automatically?
Thanks!
I am using DynamicData in the version that shipped with VS2008.
In the default List view, the data is sorted by order of entry into the database. I'd like to get it sorted by a field of a specific name (descending).
As a last resort I tried to use the OrderByParameter of the LinqDataSource with a QueryStringParameter, but I could not get it to sort anything. =)
Is there an easy way to accomplish this?
Is there a cleaner way to do the following, assuming that I have a reason to keep the data sets independent?:
x = {1, 2, 3};
y = {1, 4, 9};
ListPlot[Partition[Riffle[x, y], 2]]
Thanks!
Say I've written a simple app that draws circles in browser. Now I'd like to let people save their pictures. How would I store the data on the server? Which format would be the best option? Should I simply store the relevant html? What would be the case when I would want to make a custom format that is stored on the server and parsed back to html canvas when loaded?
I'm trying to use a simple mysql database but tweak it so that every field is backed up up to an indefinite number of versions. The best way I can illustrate this is by replacing each and every field of every table with a stack of all the values this field has ever had (each of these values should be timestamped). I guess it's kind of like having customized version control for all my data..
Any ideas on how to do this?
