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.
Is there any way to access the Windows Event Log from a java class. Has anyone written any APIs for this, and would there be any way to access the data from a remote machine?
The scenario is:
I run a process on a remote machine, from a controlling Java process.
This remote process logs stuff to the Event Log, which I want to be able to see in the controlling process.
Thanks in advance.
I have created a database model in Visio Professional (2003). I know that the Enterprise version has the ability to create a DB in Sql Server based on the data in Visio. I do not have the option to install Enterprise. Aside from going through the entire thing one table and relationship at a time and creating the whole database from scratch, by hand, can anyone recommend any tool/utility/method for converting the visio database model into a Sql Script that can be used to create a new DB in Sql Server?
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?
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.

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
I am reading the Head First PHP/Mysql book and they say to store both the user's username, email into cookies and sessions. Is it safe to assume that everyone nowadays accepts cookies? Or should I store both in sessions and cookies?
I am not storing any sensitive data in cookies such as password, etc.
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!
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!
I am using PHP's function file_get_contents() to fetch contents of a URL and then I process headers through the variable $http_response_header. Now the problem is that some of the URLs need some data to be posted to the URL (for example, login pages). How do I do that?
I realize using stream_context I may be able to do that but I am not entirely clear.
Thanks.

Using MATLAB I filtered a very noisy m x n array with a low-pass Gaussian filter, cleaned it up pretty well but still not well enough to analyze my data. What would the next step be? I'm thinking that signal enhancement, but am not sure how to go about this.
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?
