• Math Question: Is it possible to calculate the row position as you loop through a cartesian product

  - by Kuyenda

  Is it possible to calculate the row position in the cartesian product of two arrays? For example if you have one array of two rows and another of three rows it's easy to calculate the size of the cartesian product (Array1.Rows.Count * Array2.Rows.Count = 6), but you can't iterate through each array and just use the product of the respective row positions to calculate the row position in the cartesian product. Array1.Row * Array2.Row 1 * 1 = 1 1 * 2 = 2 2 * 1 = 2 2 * 2 = 4 3 * 1 = 3 3 * 2 = 6 Is there a formula to obtain the result 1, 2, 3, 4, 5, 6 from Array1.Row and Array2.Row as you iterate through them in the following fashion: For 1 To Array1.Rows.Count For 1 To Array2.Rows.Count 'some formula here to get cartesian row position' Next Array2.Row Next Array1.Row Thanks!

• Backup Google Calendar programmatically: https://www.google.com/calendar/exporticalzip

  - by Michael

  I'm struggling with writing a python script that automatically grabs the zip fail containing all my google calendars and stores it (as a backup) on my harddisk. I'm using ClientLogin to get an authentication token (and successfully can obtain the token). Unfortunately, i'm unable to retrieve the file at https://www.google.com/calendar/exporticalzip It always asks me for the login credentials again by returning a login page as html (instead of the zip). Here's the critical code: post_data = post_data = urllib.urlencode({ 'auth': token, 'continue': zip_url}) request = urllib2.Request('https://www.google.com/calendar', post_data, header) try: f = urllib2.urlopen(request) result = f.read() except: print "Error" Anyone any ideas or done that before? Or an alternative idea how to backup all my calendars (automatically!)

• Extension method return using generics

  - by Steven de Salas

  Is it possible to return a generic type using extension methods? For example, I have the following method: // Convenience method to obtain a field within a row (as a double type) public static double GetDouble(this DataRow row, string field) { if (row != null && row.Table.Columns.Contains(field)) { object value = row[field]; if (value != null && value != DBNull.Value) return Convert.ToDouble(value); } return 0; } This is currently used as follows: double value = row.GetDouble("tangible-equity"); but I would like to use the following code: double value = row.Get<double>("tangible-equity"); Is this possible and if so, what would the method look like?

• Problem configuring application specific loggin glassfish v3

  - by Shane

  I am using java.util.logging in an EJB application running on glassfish v3. I can see the log messages in server.log but i don't seem to be able to configure the logging level in glassfish\domains\domain1\logging.properties. If I use: Logger logger = Logger.getLogger("com.foo"); To obtain the logger and log with: logger.info("message"); then I expect that if I set com.foo.level=WARNING in logging.properties then the message should not logged. Am I doing something wrong here?

• Dynamically adding @property in python

  - by rz

  I know that I can dynamically add an instance method to an object by doing something like: import types def my_method(self): # logic of method # ... # instance is some instance of some class instance.my_method = types.MethodType(my_method, instance) Later on I can call instance.my_method() and self will be bound correctly and everything works. Now, my question: how to do the exact same thing to obtain the behavior that decorating the new method with @property would give? I would guess something like: instance.my_method = types.MethodType(my_method, instance) instance.my_method = property(instance.my_method) But, doing that instance.my_method returns a property object.

• What states does my route travel through?

  - by Bert Smith

  I've got a page that has a map with a starting and ending location. I run a route between them to get the nifty line showing the route. I'm currently using Bing but have attempted with Google as well. I'd like to know which states this route passes through so I can then overlay those states with specific information. Any suggestions on how to obtain this would be most appreciated. I'm using the AJAX SDK's for both Bing and Google. Handling all the local stuff with js/jquery.

• Import de-normalized relational data from Excel into SQL Server

  - by roryf

  I need to import data from an Excel spreadsheet into SQL Server, but the data isn't in a relational/normalized format so the import wizard isn't going to cut it (as far as I know). The data is in this format: Category SubCategory Name Description Category#1 SubCategory#1 Product#1 Description#1 Category#1 SubCategory#1 Product#2 Description#2 Category#1 SubCategory#2 Product#3 Description#3 Category#1 SubCategory#2 Product#4 Description#4 Category#2 SubCategory#3 Product#5 Description#5 (apologies I'm lacking the inventiveness to come up with 'real' data at this time in the morning...) Each row contains a unique product, but the cateogry structure is duplicated. I want to import this data into three tables: Category SubCategory Product (I know SubCategory should really be contained within Category, DB was not my design) I need a way to import unique rows based on the Category and then SubCategory columns, and then when importing the other columns into Product, obtain a reference to the SubCategory based on name. Short of scripting this, is there any way to do it using the import wizard or some other tool?

• jQuery switchClass

  - by Eric

  Is it possible to undo a switchClass transaition? I'd like an element to slowly obtain class A as you hover over it, and slowly lose it again once the mouse has moved away. However, the function appears to be glitchy, and calling .stop(0,1) doesn't seem to help. In fact, it seems to break it. I have a live example here. Yes, it's a 404 page, but that's not important. The navigation should be slowly gaining or losing a class, but it just jumps. The script can be found here. Is such a transition possible?

• How do I construct a 3D model of a room from 2 stereo cameras? What is the determining factor to an

  - by yasumi

  Currently, I have extracted depth points to construct a 3D model from 2 stereo cameras. The methods I have used are openCV graphCut method and a software from http://sourceforge.net/projects/reconststereo/. However, the generated 3D models are not very accurate, which leads me to question: 1) What is the problem with pixel-based method? 2) Should I change my pixel-based method to feature-based or object-recognition-based method? Is there a best method? 3) Are there any other ways to do such reconstruction? Additionally, the depth extracted comes only from 2 images. What if I am turning the camera 360 degrees to obtain a video? Looking forward to suggestion on how to combine this depth information. Thank you very much :)

• Can I use a stream to INSERT or UPDATE a row in SQL Server (C#)?

  - by Cheeso

  Suppose I have a VarBinary[MAX] column, can I insert or update into that column using a type derived from System.IO.Stream? How? I think that I can obtain a read-only stream from such a column using a SqlDataReader, calling GetSqlBytes() on the reader, getting the SqlBytes instance, and then referencing the Stream property on that. What I want is the converse - I want a stream for update or insert. Possible? (from c#... Without writing T-SQL ?)

• how do copyright permission systems for content hosting sites work?

  - by zebraman

  I am wondering about subscription sites that host content, like recorded performances from concerts. I'm sure there is a tangle of copyright permissions that must be granted for these video/audio files to be hosted. For example, if a band plays a cover of another band's song, permission must be obtained from not only the band that performed, but the band that owns the song. Perhaps even from the venue that hosted the performance, to record the video and post the content. I am curious how websites that host content like this work. How might an automated copyright system work to keep track of who has ownership of certain performances and obtain permission from said owners to record and post their content.

• How can I (both) create a row and accessing that row in the same 'Stored Procedure'?

  - by Richard77

  Hello, I'd like to get the value of the id column for an object just after I've created it. But I don't want to run another query for that. My book for beginner (SQL Server 2008 for Dummies) says that there are 2 tables (inserted and deleted) that hold the last row(s) that have been inserted, updated, or deleted. Unfortunately, only Triggers (says the book) can access those tables. But, if I use triggers, they will go off each time I "insert" a row even when I don't need them that functionality. Can I obtain the same effect with a Store Procedure (without having to run a separate query?) This is what I'm trying to do CREATE PROCEDURE myProcedure DECLARE @OrganizationName @ColumnID OUTPUT AS INSERT INTO Organization (OrganizationName) VALUES (@OrganizationName) SET @ColumnID = (// Please, I need Help here ...) Thanks for helping

• FastCGI C++ program and missing SCRIPT_NAME

  - by Simone Margaritelli

  Hi guys, i'm studying the fastcgi developement kit because i'm writing a new scripting language and i'd like to write a fastcgi version of the interpreter to run scripts as webpages. I'm using this example from the sdk, located at /srv/http/bin/echocpp So, in my httpd.conf file, i have the following lines : FastCgiServer /srv/http/bin/echocpp -idle-timeout 120 -processes 4 ScriptAlias / /srv/http/bin/echocpp/ ... ... AddHandler fastcgi-script hy Where 'hy' is the extensions of my scripts. Then, when i try browse, for instance http://localhost/~evilsocket/prime.hy I see all the environment variables as expected from the echo-cpp.cpp programm, except for the SCRIPT_NAME that is empty. Is there something i'm missing out of this? How am i supposed to obtain the full path of the script to run it inside my fastcgi version of the interpreter? Thanks

• My app crashes on Iphone SDK 3.2

  - by Mladen

  Hi Guys, My app worked ok on iPhone SDK 3.1. However, when I try to run it in 3.2 simulator, I get the following error and it crashes: bool _WebTryThreadLock(bool), 0x5148280: Tried to obtain the web lock from a thread other than the main thread or the web thread. This may be a result of calling to UIKit from a secondary thread. Crashing now... Program received signal: “EXC_BAD_ACCESS”. When I debug it, it leads me to this peace of code: - (void)LoginViewToCheckView:(id)sender { CheckViewController *tempTestController = [[CheckViewController alloc] initWithStyle:UITableViewStyleGrouped]; [tempTestController setDelegate:self]; [self setCheckViewController: tempTestController]; [tempTestController release]; [navigationController pushViewController:checkViewController animated:YES];} Other thing worth mentioning is maybe that I am calling this function from a separate thread. Any ideas what could be wrong?

• Is it possible to query a XML file with SQL?

  - by Monty

  Currently I'm working on a case where we don't want to change to much on a c#/wpf program, but like to add a feature. Currently we allow certain users to add sql queries to a database to retrieve customer data, hereby a custom connection string/ provider name must be specified. With this information it's possible to create the connection and obtain the data with c#. However we like to add the possibility to allow that user group to query XML files too, with a certain connection string/ provider name. I just had a look for possibities in .net to do that, but can't seem to find a decent way... Is something like this possible? (OleDb/ODBC way maybe?) Thanks in advance.

• Uniform distribution of binary values in Matlab

  - by JohnIdol

  I have a requirement for the generation of a given number N of vectors of given size each consistent of a uniform distribution of 0s and 1s. This is what I am doing at the moment, but I noticed that the distribution is strongly peaked at half 1s and half 0s, which is no good for what I am doing: a = randint(1, sizeOfVector, [0 1]); The unifrnd function looks promising for what I need, but I can't manage to understand how to output a binary vector of that size. Is it the case that I can use the unifrnd function (and if so how would be appreciated!) or can is there any other more convenient way to obtain such a set of vectors? Any help appreciated!

• Drawing rectangles on a grid in a web browser

  - by Dhruv

  I would like to create an online, simple WYSIWYG drawing editor allowing people to draw rectangular shapes. I'm thinking of a grid which the lines and points can snap on to, ensuring that the lines are strictly vertical or horizontal. I will be parsing the rectangular shapes to obtain some area calculations and compute certain things. How can I achieve the drawing ability? The new canvas tag is good but people have been telling me that IE does not support it. I found some Java applets but I have never programmed in Java before. Is there a way to do this using pure javascript or jquery? Does ASP.NET help at all? Thanks.

• Get local network interface addresses using only proc?

  - by Matt Joiner

  How can I obtain the (IPv4) addresses for all network interfaces using only proc? After some extensive investigation I've discovered the following: ifconfig makes use of SIOCGIFADDR, which requires open sockets and advance knowledge of all the interface names. It also isn't documented in any manual pages on Linux. proc contains /proc/net/dev, but this is a list of interface statistics. proc contains /proc/net/if_inet6, which is exactly what I need but for IPv6. Generally interfaces are easy to find in proc, but actual addresses are very rarely used except where explicitly part of some connection. There's a system call called getifaddrs, which is very much a "magical" function you'd expect to see in Windows. It's also implemented on BSD. However it's not very text-oriented, which makes it difficult to use from non-C languages.

• Can't get flat QToolButton with border on hover stylesheet

  - by Max

  Hi, all! I need to implement textbox with inplace button (for search or filter purposes). So, I need to get Qtoolbutton, that is flat and rendered as icon, and obtain the border when hovered by mouse or pressed. And maybe I'd add some almost transparent background on hover too. I tried to set the following stylesheet: 'border: none; hover {border: 1px} pressed {border: 1px}' , but it seems that only border set. I tried to set autoRaise() to True and False, I mean, maybe some intersection occured, but haven't succeed.

• C++: conjunction of binds?

  - by Helltone

  Suppose the following two functions: #include <iostream> #include <cstdlib> // atoi #include <cstring> // strcmp #include <boost/bind.hpp> bool match1(const char* a, const char* b) { return (strcmp(a, b) == 0); } bool match2(int a, const char* b) { return (atoi(b) == a); } Each of these functions takes two arguments, but can be transformed into a callable object that takes only one argument by using (std/boost)bind. Something along the lines of: boost::bind(match1, "a test"); boost::bind(match2, 42); I want to be able to obtain, from two functions like these that take one argument and return bool, a callable object that takes two arguments and returns the && of the bools. The type of the arguments is arbitrary. Something like an operator&& for functions that return bool.

• Django ORM dealing with MySQL BIT(1) field

  - by Carles Barrobés

  In a Django application, I'm trying to access an existing MySQL database created with Hibernate (a Java ORM). I reverse engineered the model using: $ manage.py inspectdb > models.py This created a nice models file from the Database and many things were quite fine. But I can't find how to properly access boolean fields, which were mapped by Hibernate as columns of type BIT(1). The inspectdb script by default creates these fields in the model as TextField and adds a comment saying that it couldn't reliably obtain the field type. I changed these to BooleanField but it doesn't work (the model objects always fetch a value of true for these fields). Using IntegerField won't work as well (e.g. in the admin these fields show strange non-ascii characters). Any hints of doing this without changing the database? (I need the existing Hibernate mappings and Java application to still work with the database).

• Storing/Quering multiple value in SQLite

  - by chmod

  I'm trying to store a blooming season in month for each tree in SQLite3. Currently I had the field "month" then I store the month name in the field. For example Tree Name Month Tree1 Jan,Feb,Mar Tree2 Nov,Dec,Jan Tree3 Jan,Feb,Mar,Apr,May,Jun,Jul,Aug,Sep,Oct,Nov,Dec Tree4 Mar,Apr,Nov,Dec Tree5 Jan,Feb,Mar,Apr I'm not sure if this is the best way to store it, Any recommendation is appreciate. Secondly, I need to perform a query where I enter in the month and it should return me the tree name that match the search criteria. For example If I search for "Jan" the result should be Tree1,Tree2,Tree3,Tree5 "Jan,Feb,Mar" the result should be Tree1,Tree3,Tree5 "Jan,Feb,Mar,Apr" the result should be Tree5 "Sep,Oct,Nov,Dec" the result should be none Which SQL query do I have to use in order to obtain the above result? Thanks
