• How to set Android Google Maps API v2 map to show whole world map?

  - by Joao

  I am developing an android application that uses a google map in the background. When I start the application, I want to display a map of the hole word. According to the android google maps API v2: https://developers.google.com/maps/documentation/android/views the way to set a specific zoom value is "CameraUpdateFactory.zoomTo(float)" and the same api https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/CameraUpdateFactory#zoomTo(float) tells that the minimum argument to this function is 2. but when I call the function: mMap.moveCamera(CameraUpdateFactory.zoomTo(2)); The viewport of the world map is just a little bigger than Australia... How can I display the entire world map at once? Thanks in advance, João

• Get a tableview insertRowsAtIndexPaths to accept indexOfObject?

  - by Emil

  Hey. I have a code snippet that looks like this: [tableView beginUpdates]; [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationLeft]; [tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[array indexOfObject:[array objectAtIndex:indexPath.row]]] withRowAnimation:UITableViewRowAnimationLeft]; [tableView endUpdates]; [tableView reloadData]; It gets executed when a user clicks on an accessory. The first part is only there to provide a smooth animation, and does not really matter, as the tableView is reloaded milliseconds later, but as I said, it's there to provide an animation. It is supposed to move a selected object from its current indexPath to the value from an array at the same indexPath. Obviously, this code does not work, so I just want to know what can be done to fix it? PS: I get a warning when compiling, too. The usual "passing argument 1 of 'arrayWithObject:' makes pointer from integer without a cast..." (line 3)

• Does C# have an equivalent to Scala's structural typing?

  - by Tom Morris

  In Scala, I can define structural types as follows: type Pressable { def press(): Unit } This means that I can define a function or method which takes as an argument something that is Pressable, like this: def foo(i: Pressable) { // etc. The object which I pass to this function must have defined for it a method called press() that matches the type signature defined in the type - takes no arguments, returns Unit (Scala's version of void). I can even use the structural type inline: def foo(i: { def press(): Unit }) { // etc. It basically allows the programmer to have all the benefits of duck typing while still having the benefit of compile-time type checking. Does C# have something similar? I've Googled but can't find anything, but I'm not familiar with C# in any depth. If there aren't, are there any plans to add this?

• Drupal using views with CCK custom fields

  - by jackbot

  I've got a Drupal site which uses a custom field for a certain type of node (person_id) which corresponds to a particular user. I want to create a view so that when logged in, a user can see a list of nodes 'tagged' with their person_id. I've got the view working fine, with a url of my-library/username but replacing username with a different username shows a list of all nodes tagged with that user. What I want to do is stop users changing the URL and seeing other users' tagged nodes. How can I do this? Is there somewhere where I can dictate that the only valid argument for this page is the one that corresponds with the current logged in user's username?

• Building a Com addin for Office 2000 / Office 2007

  - by Stuart

  I am struggling to find a straight forward guide to creating office addins using VSTO and VB.net. Specifically I would like to know how to be able to create a addin/ dll which can either be referenced from VBA in the form:- Addin.method(argument) or Addin.property = X Or which would install its own custom toolbars/ ribbon interface to an aspect of office for example Word. I've checked MSDN and in terms of legibility and usability of the explanations I have drawn a blank so far. I currently have a requirement to create at least one addin for Office 2000 to run and manipluate SQL and then a suite of addins for a customized Office 2007 (Word) set-up.

• Create Custom Builds of an Xcode Project

  - by macinjosh

  I am going to build a Mac application written in Obj-C with Xcode. For argument's sake let's say it will have 10 optional features. I need a way to enable or disable those features to create custom builds of the application. These builds would be automated (most likely through the Mac OS X Terminal) so I would need a way to state which of these features are enabled/disabled at build time (a configuration file or CLI arguments would be ideal.) So what is the best way to accomplish this? I'm trying to plan this out before I start coding so that there is proper separation in my code base to allow for these features to come and go. Ideally the custom build would only contain compiled code for the features it should have. In other words I don't want to always compile all the features and condition them out at runtime.

• Verify method with Delegate parameter in Moq

  - by Hans Løken

  I have a case where I want to verify that a method that takes a Delegate parameter is called. I don't care about the particular Delegate parameter supplied I just want to make sure that the method is in fact called. The method looks like this: public interface IInvokerProxy{ void Invoke(Delegate method); ... } I would like to do something like this: invokerProxyMock.Verify( proxy => proxy.Invoke( It.IsAny<Delegate>)); Currently it gives me an error Argument '1': cannot convert from 'method group' to 'System.Delegate'. Does anyone know if this is possible?

• nmake.exe: is there a way to exclude a file from a set of files specified in a macro?

  - by Cheeso

  I'm looking for something like the Exclude filter for msbuild, but I Want it in a makefile processed by nmake. Is that possible? Suppose I have a makefile that defines this macro: SOURCES=xxx.c yyy.c zzz.c and I invoke it with nmake OLD=xxx.c NEW=bbb.c ...can I produce, within the makefile, a macro with a value like: yyy.c zzz.c bbb.c ...basically substituting bbb.c for xxx.c ? The files can appear in any order. This would be pretty easy if the string substitution that is possible in nmake macros, allowed for evaluation of macros. In other words, I can do sources=xxx.c yyy.c zzz.c objs=$(sources:.c=.o) and the value of $(objs) is xxx.o yyy.o zzz.o But nmake does not allow a macro for the value of either argument to that substitution. I cannot do this: new=.o sources=xxx.c yyy.c zzz.c objs=$(sources:.c=$(new))

• Code Golf Christmas Edition: How to print out a Christmas tree of height N

  - by TheSoftwareJedi

  Given a number N, how can I print out a Christmas tree of height N using the least number of code characters? N is assumed constrained to a min val of 3, and a max val of 30 (bounds and error checking are not necessary). N is given as the one and only command line argument to your program or script. All languages appreciated, if you see a language already implemented and you can make it shorter, edit if possible - comment otherwise and hope someone cleans up the mess. Include newlines and whitespace for clarity, but don't include them in the character count. A Christmas tree is generated as such, with its "trunk" consisting of only a centered "*" N = 3: * *** ***** * N = 4: * *** ***** ******* * N = 5: * *** ***** ******* ********* * N defines the height of the branches not including the one line trunk. Merry Christmas SO!

• PGU Tiles collision detection

  - by user280454

  Hi, I've been using PGU(Phil's Pygame Utilities) for a while. It has a dictionary called tdata, which is passed as an argument while loading tiles tdata = { tileno:(agroup, hit_handler, config)} I'm making a pacman clone in which I have 2 groups : player and ghost, for which I want to collision detection with the same type of tile. For example, if the tile no is 2, I want this tile to have agroups as both player and ghost. I tried doing the following: tdata = {0x02 :('player', tile_hit_1, config), 0x02 : ('ghost', tile_hit_2, config)} However, on doing this, it only gives collision detection for ghost, not the player. Any ideas on how I can do collision detection for both the player and the ghost with the same type of tile?

• Finisar SQLite Problem with ParameterDirection

  private int GetNextId() { SQLiteConnector conn = new SQLiteConnector(false); conn.OpenConnection(); cmd = new SQLiteCommand("SELECT @id_account = MAX(id_account) FROM account"); SQLiteParameter param = new SQLiteParameter("@id_account", DbType.Int32); param.Direction = ParameterDirection.Output; cmd.Parameters.Add(param); cmd = conn.ExecuteReadeOutput(cmd); conn.Close(); return int.Parse(cmd.Parameters["id_account"].Value.ToString()) + 1; } ... public SQLiteCommand ExecuteReadeOutput(SQLiteCommand cmd) { conn.Open(); cmd.Connection = conn; reader = cmd.ExecuteReader(); reader.Close(); return cmd; } When I call the method GetNextId() occur the following error: Specified argument was out of the range of valid values. at line: param.Direction = ParameterDirection.Output; Any idea?

• How can I get the name of the uploaded file in HTML::Mason?

  - by marghi

  Recently I've been trying to get some files uploaded on to my server in my HTML::Mason application. All good, no problems there. Apparently Mason returns a filehandle directly in the argument. The problem is that I cannot retrieve the filename from that filehandle in a elegant way. One method of resolving this issue is parsing the filename on the client before sending it to the server and placing the extracted value in a hidden field so that it gets sent upon submit. BUT that is very unsafe!

• Why the good append syntax is so ugly, asks python newbie

  - by Cawas

  Now following my series of "python newbie questions" and based on another question. Go to http://python.net/~goodger/projects/pycon/2007/idiomatic/handout.html#other-languages-have-variables and scroll down to "Default Parameter Values". There you can find the following: def bad_append(new_item, a_list=[]): a_list.append(new_item) return a_list def good_append(new_item, a_list=None): if a_list is None: a_list = [] a_list.append(new_item) return a_list So, question here is: why is the "good" syntax over a known issue ugly like that in a programming language that promotes "elegant syntax" and "easy-to-use"? Why not just something in the definition itself, that the "argument" name is attached to a "localized" mutable object like: def better_append(new_item, a_list=[].local): a_list.append(new_item) return a_list I'm sure there would be a better way to do this syntax, but I'm also almost positive there's a good reason to why it hasn't been done. So, anyone happens to know why?

• Why I add the CGPoint in the NSMultable Array?

  - by Tattat

  I want to store my CGPoint to the NSMultable Array, so , I have method like this: [self.points addObject:CGPointMake(x, y)]; But I got the error, it said that : Incompatible type for argument 1 of "addObject". So, I check out the API, (void)addObject:(id)anObject anObject The object to add to the end of the receiver's content. This value must not be nil. So, I think the "CGPointMake" can make a Object, but it can't be assigned. What happens?

• Button in gridview

  - by Rajeev

  I'm using a button in a template field of gridview. On button click I want to redirect to another page but it throws an exception: Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" % in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. What can I do to resolve this problem?

• Socksifying a Java ServerSocket - how to approach

  - by Thorbjørn Ravn Andersen

  I would like to have a Java program running on network A have a ServerSocket living on another network B through a proxy. I have played with a SOCKS5 proxy (which works) but it appears that all the proxy facilities in Java only work with client connections, not with ServerSockets (no constructor taking a Proxy argument). Asking Google gives much hay and few needles. What is the approach I should take to get this running? If a specific client is better than a generic SOCKS or web proxy then fine, but it needs to be Java (that leaves sshd out). Target JVM is preferrably Java 5, and then Java 6.

• AudioQueueOfflineRender returning empty data

  - by hyn

  I'm having problems using AudioQueueOfflineRender to decode AAC data. When I examine the buffer after the call, it is always filled with empty data. I made sure the input buffer is valid and packet descriptions are provided. I searched and found that a few others have had the same problem: http://lists.apple.com/archives/Coreaudio-api/2008/Jul/msg00119.html Also, the inTimestamp argument doesn't make sense to me. Why should the renderer care where in the audio the beginning of the buffer corresponds to? The function throws an error if I pass in NULL, so I pass in the timestamp anyway.

• myth about factory pattern

  - by leiz

  This has bothered me for awhile, and I have no clues if this is a myth. It seems that a factory pattern can ease the pain of adding a dependency for a class. For example, in a book, it has something like this Suppose that you have a class named Order. Initially it did not depend on anything. Therefore you didn't bother using a factory to create Order objects and you just used plain new to instantiate the objects. However, you now have a requirement that Order has to be created in association with a Customer. There are million places you need to change to add this extra parameter. If only you had de?ned a factory for the Order class, you would have met the new requirement without the same pain. How is this not same pain as adding an extra parameter to the constructor? I mean you would still need to provide an extra argument for the factory and that is also used by million places, right?

• Mapping functions of 2D numpy arrays

  - by perimosocordiae

  I have a function foo that takes a NxM numpy array as an argument and returns a scalar value. I have a AxNxM numpy array data, over which I'd like to map foo to give me a resultant numpy array of length A. Curently, I'm doing this: result = numpy.array([foo(x) for x in data]) It works, but it seems like I'm not taking advantage of the numpy magic (and speed). Is there a better way? I've looked at numpy.vectorize, and numpy.apply_along_axis, but neither works for a function of 2D arrays. EDIT: I'm doing boosted regression on 24x24 image patches, so my AxNxM is something like 1000x24x24. What I called foo above applies a Haar-like feature to a patch (so, not terribly computationally intensive).
