• className method?

  - by fuzzygoat

  I have just been watching the Stanford iPhone lecture online from Jan 2010 and I noticed that the guy from Apple keeps referring to getting an objects class name using "className" e.g. NSArray *myArray = [NSArray arrayWithObjects:@"ONE", @"TWO", nil]; NSLog(@"I am an %@ and have %d items", [myArray className], [myArray count]); However, I can't get this to work, the closest I can come up with it to use class, is className wrong, did it get removed, just curious? NSArray *myArray = [NSArray arrayWithObjects:@"ONE", @"TWO", nil]; NSLog(@"I am an %@ and have %d items", [myArray class], [myArray count]); Gary

• C# program for finding how many numbers are devidable by 5 in give range

  - by user1639735

  My task is: Write a program that reads two positive integer numbers and prints how many numbers p exist between them such that the reminder of the division by 5 is 0 (inclusive). Example: p(17,25) = 2. Console.Write("Enter min: "); int min = int.Parse(Console.ReadLine()); Console.Write("Enter max: "); int max = int.Parse(Console.ReadLine()); Console.WriteLine("The numbers devidable by 5 without remainder from {0} to {1} are: ",min,max); for (int i = min; i <= max; i++) { if (i % 5 == 0) { Console.WriteLine(i); } } This prints out the numbers that are devidable by 5 in the range...How do I count how many are there and print the count in the console? Thanks.

• Counts of events grouped by date in python?

  - by Sologoub

  This is no doubt another noobish question, but I'll ask it anyways: I have a data set of events with exact datetime in UTC. I'd like to create a line chart showing total number of events by day (date) in the specified date range. Right now I can retrieve the total data set for the needed date range, but then I need to go through it and count up for each date. The app is running on google app engine and is using python. What is the best way to create a new data set showing date and corresponding counts (including if there were no events on that date) that I can then use to pass this info to a django template? Data set for this example looks like this: class Event(db.Model): event_name = db.StringProperty() doe = db.DateTimeProperty() dlu = db.DateTimeProperty() user = db.UserProperty() Ideally, I want something with date and count for that date. Thanks and please let me know if something else is needed to answer this question!

• Alternative to 'where col in (list)' for MySQL

  - by user210481

  Hi I have the following table T: id 1 2 3 4 col a b a c I want to do a select that returns the id,col when group by(col) having count(col)1 One way of doing it is SELECT id,col FROM T WHERE col IN (SELECT col FROM T GROUP BY(col) HAVING COUNT(col)>1); The intern select (from the right) returns 'a' and main one (left) will return 1,a and 3,a The problem is that the where in statement seems to be extremely slow. In my real case, the results from the internal select has many 'col's, something about 70000 and it's taking hours. Right now it's much faster to do the internal select and the main select getting all ids and upcs and do the intersection locally. MySQL should be able to handle this kind of query efficiently. Can I substitute the where in for a join or something faster? Thanks

• What's the proper way of importing option lists into an Android app?

  - by Scott

  I have been storing option lists for my Android app in a cloud table. For example, categories like "historical fiction","biography","science fiction", etc. I see the following pros and cons: Pro: I can make changes to the list without sending an app update to Google Play Not normalized - I can use the text in my other data tables instead of a reference ID Con: App needs to take time to download from the web each time (or at least check for changes) English only I believe the "proper" way to do this is the use the XML resource files. But I need to make sure the selection references correctly with my data. That is, my app needs to understand that "Poetry" and "Poesía" are the same thing. Is the correct thing to do: Forget about it since I'll never get to the point where I'm translating my app anyway Use a string-array and use the index (0...x) to know what the selection is Use a 2-dimensional string-array with a reference ID in the first column and the text in the second?

• JPA Database strcture for internationalisation

  - by IrishDubGuy

  I am trying to get a JPA implementation of a simple approach to internationalisation. I want to have a table of translated strings that I can reference in multiple fields in multiple tables. So all text occurrences in all tables will be replaced by a reference to the translated strings table. In combination with a language id, this would give a unique row in the translated strings table for that particular field. For example, consider a schema that has entities Course and Module as follows :- Course int course_id, int name, int description Module int module_id, int name The course.name, course.description and module.name are all referencing the id field of the translated strings table :- TranslatedString int id, String lang, String content That all seems simple enough. I get one table for all strings that could be internationalised and that table is used across all the other tables. How might I do this in JPA, using eclipselink 2.4? I've looked at embedded ElementCollection, ala this... JPA 2.0: Mapping a Map - it isn't exactly what i'm after cos it looks like it is relating the translated strings table to the pk of the owning table. This means I can only have one translatable string field per entity (unless I add new join columns into the translatable strings table, which defeats the point, its the opposite of what I am trying to do). I'm also not clear on how this would work across entites, presumably the id of each entity would have to use a database wide sequence to ensure uniqueness of the translatable strings table. BTW, I tried the example as laid out in that link and it didn't work for me - as soon as the entity had a localizedString map added, persisting it caused the client side to bomb but no obvious error on the server side and nothing persisted in the DB :S I been around the houses on this about 9 hours so far, I've looked at this Internationalization with Hibernate which appears to be trying to do the same thing as the link above (without the table definitions it hard to see what he achieved). Any help would be gratefully achieved at this point... Edit 1 - re AMS anwser below, I'm not sure that really addresses the issue. In his example it leaves the storing of the description text to some other process. The idea of this type of approach is that the entity object takes the text and locale and this (somehow!) ends up in the translatable strings table. In the first link I gave, the guy is attempting to do this by using an embedded map, which I feel is the right approach. His way though has two issues - one it doesn't seem to work! and two if it did work, it is storing the FK in the embedded table instead of the other way round (I think, I can't get it to run so I can't see exactly how it persists). I suspect the correct approach ends up with a map reference in place of each text that needs translating (the map being locale-content), but I can't see how to do this in a way that allows for multiple maps in one entity (without having corresponding multiple columns in the translatable strings table)...

• Hibernate object equality checking

  - by Sujee

  As far as I understand(correct me if I am wrong) Hibernate uses object reference to check the object equality. When Hibernate identifies that there are more than one objects attached to same DB record, it throws following exception. "a different object with the same identifier value was already associated with the session" My question is, does Hibernate use equal() method to check the object equality (The default equal method uses object reference)? If it is true, will overridden equal() method change the Hibernate behavior? Note: My question is not about the issues of implementing equal() or hashCode() methods in a Hibernate persisted object. Thank you.

• Does .NET have a linker?

  - by Water Cooler v2

  From Jon Skeet's blog: What does the following comment mean? // The line below only works when linked rather than // referenced, as otherwise you need a cast. // The compiler treats it as if it both takes and // returns a dynamic value. string value = com.MakeMeDynamic(10); I understand what referencing an assembly is. You may reference it when compiling the program files either using the /ref: switch at the command line or you may add a statically reference to the assembly in Visual Studio. But how do you link to an assembly in .NET? Does he mean, load the assembly using Reflection (Assembly.LoadFile())? Or, the Win32 API LoadLibrary()? Or, does .NET have a linker that I have never heard of?

• Is there a memory leak here?

• Why does get_posts() return only 5 matching posts, when it should return 9?

  - by Scott B

  global $post; $cat1=get_cat_ID('test1'); $cat2=get_cat_ID('test2'); $myrecentposts = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat1,-$cat2",'showposts' => 5)); $myrecentposts2 = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat1,-$cat2")); $myrecentpostscount = count($myrecentposts2); echo $myrecentpostscount; The value of the echo is 5 (the correct value should be 9). The only way I can get it to return the correct value for the post count is to change the $myrecentposts2 calculation as follows... $myrecentposts2 = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat1,-$cat2",'showposts' => 999));

• data structure for counting frequencies in a database table-like format

  - by user373312

  i was wondering if there is a data structure optimized to count frequencies against data that is stored in a database table-like format. for example, the data comes in a (comma) delimited format below. col1, col2, col3 x, a, green x, b, blue ... y, c, green now i simply want to count the frequency of col1=x or col1=x and col2=green. i have been storing the data in a database table, but in my profiling and from empirical observation, database connection is the bottle-neck. i have tried using in-memory database solutions too, and that works quite well; the only problem is memory requirements and quirky init/destroy calls. also, i work mainly with java, but have experience with .net, and was wondering if there was any api to work with "tabular" data in a linq way using java. any help is appreciated.

• Using Enums that are in an external dll C#

  - by user1443233

  I have a project I am working that will involve creating one DLL that will be used across multiple other sites. Inside this DLL we need to reference about 10 Enums. The values of these Enums however will be different for each site the DLL is used on. For example: MyBase.dll may have a class MyClass with an attribute of type MyEnum. MyBase.dll is then referenced in MySite. MyStie will also reference MyEnums.dll which will contain the values for the MyEnum type. Is there any way to accomplish this? While building MyBase.dll, I know what enums will exist in side of MyEnums.dll. The problem is I cannot build MyBase.dll without specifically referenceing the MyEnums.dll, which is not created until the MyBase.dll is used in a specific project. I hope that makes sense and hope I can find an answer here. Thanks.

• Database design for a Fantasy league

  - by Samidh T

  Here's the basic schema for my database Table user{ userid numeber primary key, count number } Table player{ pid number primary key, } Table user-player{ userid number primary key foreign key(user), pid number primary key foreign key(player) } Table temp{ pid number primary key, points number } Here's what I intend to do... After every match the temp table is updated which holds the id of players that played the last match and the points they earned. Next run a procedure that will match the pid from temp table with every uid of user-player table having the same pid. add the points from temp table to the count of user table for every matching uid. empty temp table. My questions is considering 200 players and 10000 users,Will this method be efficient? I am going to be using mysql for this.

• Calling web service methods using URLs

  - by Alka

  Hi. So, i have a central web service that is responsible for managing other services. These services register in the main WS with their URL, leading to their own web service. what i need to do now is call the child web services from the central web service. I've searched google on how to do this but all i could find was this. I would like to register any web service and not create a web reference, as suggested in the solution i've found. How is this done without using a web reference?

• cellForRowAtIndexPath called too late

  - by Mihai Fonoage

  Hi, I am trying to re-load a table every time some data I get from the web is available. This is what I have: SearchDataViewController: - (void)parseDatatXML { parsingDelegate = [[XMLParsingDelegate alloc] init]; parsingDelegate.searchDataController = self; // CONTAINS THE TABLE THAT NEEDS RE-LOADING; ImplementedSearchViewController *searchController = [[ImplementedSearchViewController alloc] initWithNibName:@"ImplementedSearchView" bundle:nil]; ProjectAppDelegate *delegate = [[UIApplication sharedApplication] delegate]; UINavigationController *nav = (UINavigationController *)[delegate.splitViewController.viewControllers objectAtIndex: 0]; NSArray *viewControllers = [[NSArray alloc] initWithObjects:nav, searchController, nil]; self.splitViewController.viewControllers = viewControllers; [viewControllers release]; // PASS A REFERENCE TO THE PARSING DELEGATE SO THAT IT CAN CALL reloadData on the table parsingDelegate.searchViewController = searchController; [searchController release]; // Build the url request used to fetch data ... NSURLRequest *dataURLRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:dataURL]]; parsingDelegate.feedConnection = [[[NSURLConnection alloc] initWithRequest:dataURLRequest delegate:parsingDelegate] autorelease]; } ImplementedSearchViewController: - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { NSLog(@"count = %d", [keys count]); // keys IS A NSMutableArray return [self.keys count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { ... cell.textLabel.text = [keys objectAtIndex:row]; ... } XMLParsingDelgate: -(void) updateSearchTable:(NSArray *)array { ... [self.currentParseBatch addObject:(NSString *)[array objectAtIndex:1]]; // RELOAD TABLE [self.searchViewController.table reloadData]; } - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qualifiedName attributes:(NSDictionary *)attributeDict { if ([elementName isEqualToString:@"..."]) { self.currentParseBatch = [NSMutableArray array]; searchViewController.keys = self.currentParseBatch; ... } ... } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName { if ([elementName isEqualToString:@"..."]) { ... [self performSelectorOnMainThread:@selector(updateSearchTable:) withObject:array waitUntilDone:NO]; } ... } My problem is that when I debug, the calls go between reloadData and numberOfRowsInSection until the keys array is filled with the last data, time at which the cellForRowAtIndexPath gets called. I wanted the table to be updated for each element I send, one by one, instead of just in the end. Any ideas why this behavior? Thank you!

• Map browser DOM using Javascript

  - by EddyR

  I'm trying to map a browsers DOM using javascript. It should list all the functions and attributes associated with it and it should also recurse through any object attributes. Now as I understand it 'window' is the most top-level node (although I've see a reference to 'top' as well in Chrome.) then 'document', etc. However I've never seen 'Node' under 'window' and yet I can call it. So where is 'Node' located? Is there a level above 'window' or is it a separate object (W3C says it's supposed to be inherited by 'document' only.)? I've been playing with a function to do this but I keep getting weird results so I'm not post it here. Alternatively - is it possible to get the properties from the object types instead of the object reference itself? for example 'DOMWindow' instead of 'window'. I think this would stop duplicating data from inherited objects.

• FOR loop performance in Javascript

  - by AndrewMcLagan

  As my research leads me to believe that for loops are the fastest iteration construct in javascript language. I was thinking that also declaring a conditional length value for the for loop would be faster... to make it clearer, which of the following do you think would be faster? Example ONE for(var i = 0; i < myLargeArray.length; i++ ) { console.log(myLargeArray[i]); } Example TWO var count = myLargeArray.length; for(var i = 0; i < count; i++ ) { console.log(myLargeArray[i]); } my logic follows that on each iteration in example one accessing the length of myLargeArray on each iteration is more computationally expensive then accessing a simple integer value as in example two?

• How can unit testing make parameter validation redundant?

  - by Johann Gerell

  We have a convention to validate all parameters of constructors and public functions/methods. For mandatory parameters of reference type, we mainly check for non-null and that's the chief validation in constructors, where we set up mandatory dependencies of the type. The number one reason why we do this is to catch that error early and not get a null reference exception a few hours down the line without knowing where or when the faulty parameter was introduced. As we start transitioning to more and more TDD, some team members feel the validation is redundant. Uncle Bob, who is a vocal advocate of TDD, strongly advices against doing parameter validation. His main argument seems to be "I have a suite of unit tests that makes sure everything works". But I can for the life of it just not see in what way unit tests can prevent our developers from calling these methods with bad parameters in production code. Please, unit testers out there, if you could explain this to me in a rational way with concrete examples, I'd be more than happy to seize this parameter validation!

• Iterator category

  In code: //I know that to get this effect (being able to use it with std algorithms) I can inherit like I did in line below: class Iterator //: public std::iterator<std::bidirectional_iterator_tag,T> { private: T** itData_; public: //BUT I WOULD LIKE TO BE ABLE TO DO IT BY HAND AS WELL typedef std::bidirectional_iterator_tag iterator_category; typedef T* value_type;//SHOULD IT BE T AS value_type or T*? typedef std::ptrdiff_t difference_type; typedef T** pointer;//SHOULD IT BE T* AS pointer or T**? typedef T*& reference;//SHOULD IT BE T& AS reference or T*&? }; Basically what I'm asking is if I have my variable of type T** in iterator class is it right assumption that value type for this iterator will be T* and so on as I described in comments in code, right next to relevant lines.

  Please check http://www.alibaba.com/catalogs/cid/702/Laptops.html they have nice filter here with number of items for each. Note one detail - they have locations here. Same thing on olx.com - location and number of items for each category. Now imagine I have tables: [products] (Id, Name, CategoryId, LocationId) [Categories] (Id,Name) [Location] (Id, Name) My question how can I do the same, cause count things even with caching looks expensive? And they give results pretty fast... Please advice with possible ways to do that in ASP.NET, C#, MVC, MS SQL, but avoice simple answers like "count and change" Thank you in advance.
