• CUDA & VS2010 problem

  - by Kristian D'Amato

  I have scoured the internets looking for an answer to this one, but couldn't find any. I've installed the CUDA 3.2 SDK (and, just now, CUDA 4.0 RC) and everything seems to work fine after long hours of fooling around with include directories, NSight, and all the rest. Well, except this one thing: it keeps highlighting the <<< >>> operator as a mistake. Only on VS2010--not on VS2008. On VS2010 I also get several warnings of the following sort: C:\Program Files (x86)\Microsoft Visual Studio 9.0\VC\include\xdebug(109): warning C4251: 'std::_String_val<_Ty,_Alloc>::_Alval' : class 'std::_DebugHeapAllocator<_Ty>' needs to have dll-interface to be used by clients of class 'std::_String_val<_Ty,_Alloc>' Anyone know how this can be fixed?

• make mongrel_rails (localhost:3000) visible to a virtual machine

  - by Max Williams

  I develop rails in ubuntu and i just set up a virtualbox windows xp virtual machine for IE testing. I'd like to be able to run mongrel_rails in ubuntu and then jump into the vm to check it out, so i can jump back, make a change, jump into the vm again, reload the page and test it, etc. Is this possible? In this sort of situation in the past i've had to set up an apache server on my dev machine and run mongrel under that, in order to get an externally visible (ie visible to my local network) ip address that i then paste into the address bar of IE in the vm. Is this really necessary? Is there a simpler way? Can i do something with my /etc/hosts or sites-available files to just make up some arbitrary network address which points to localhost:3000 in ubuntu? Or something? thanks, max

• In a client-server relationship, should the server always rethrow the exception to the client?

  - by dotnetdev

  I have a set of web services (the server), and an app which consumes this (client). In this sort of relationship, should the server always throw exceptions (ie in the throw block, rethrow the caught exception), and the client catch this. Exceptions which the server can handle, it will deal with and not rethrow, but everything else will be thrown to the calling layer for further action (the consuming app can raise a msg box or whatever). Is this a good example of an exception that can be dealt with: A file cannot be written because the directory requires special privileges, so if this raises an exception, the file is written somewhere which does not require admin rights. Thanks

• Make Java parent class not part of the interface

  - by Bart van Heukelom

  (This is a hypothetical question for discussion, I have no actual problem). Say that I'm making an implementation of SortedSet by extending LinkedHashMap: class LinkedHashSortedMapThing extends LinkedHashMap implements SortedSet { ... } Now programmers who use this class may do LinkedHashMap x = new LinkedHashSortedMapThing(); But what if I consider the extending of LinkedHashMap an implementation detail, and do not want it to be a part of the class' contract? If people use the line above, I can no longer freely change this detail without worrying about breaking existing code. Is there any way to prevent this sort of thing, other than favouring composition over inheritance (which is not always possible due to private/protected members)?

• Making self-logging modules with Log::Log4perl

  - by Oesor

  Is there a way to use Log::Log4perl to make a smart self-logging module that logs its operations to a file even in the absence of the calling script not initializing Log4perl? As far as I can tell from the documentation, the only way to use Log4perl is to initialize it in the running script from a configuration, then modules implementing Log4perl calls log themselves based on the caller's Log4perl config. Instead, I'd like the modules to provide a default initialization config for Log4perl. This would provide the default file appender for the module's category. Then, I could override this behavior by initing Log4perl in the caller with a different config if needed, and everything would hopefully just work. Is this sort of defensive logging behavior possible or am I going to need to rely on initing Log4perl in every .pl script that calls the module I want logged?

• How to make a Scala Applet whose Applet class is a singleton?

  - by Jamie

  Hi, I don't know if a solution exists but it would be highly desirable. I'm making a Scala Applet, and I want the main Applet class to be a singleton so it can be accessed elsewhere in the applet, sort of like: object App extends Applet { def init { // do init here } } Instead I have to make the App class a normal instantiatable class otherwise it complains because the contructor is private. So the ugly hack I have is to go: object A { var pp: App = null } class App extends Applet { A.pp = this def init { // do init here } } I really hate this, and is one of the reasons I don't like making applets in Scala right now. Any better solution? It would be nice...

• Easy to use/learn PHP framework?

  - by Meredith

  I need to build a php app, and I was thinking about using a framework (never used one before). I've been browsing around some but most of them seems kinda complicated, I really liked what I saw about Symfony, but it looks like I will have to spend like a month until I really understand how to use it, and in one month I could code the app I have in mind 5 times without a framework. But I want to use one to "standardize" my code and prevent bugs. So I was wondering if someone could share with me which php frameworks you think are easier to learn how to use. My application will use mysql, and it will have some sort of "search engine" to search data that will be populated on the database using a few "scraper scripts" (that I also wants to code using the framework).

• What is branched in a repository?

  - by Peter M

  Ok I hope that this will end up sounding like a reasonable question. From what I understand of subversion if you have a repo that contains multiple projects, then you can branch individual projects within that repo (see SVN Red book - Using Branches) However what I don't quite follow is what happens when you create a branch in one of the distributed systems (Git, Hg, Bazaar - I don't think it matters which one). Can you branch just a sub-directory of the repo, or when you create the branch are you branching the entire repo? This question is part of a larger one that I posted on superuser (choice and setup of version control) and has come about as I am trying to figure out how to best version control a large hierarchal layout of independent projects. It may be that for distributed systems that what I would like to do is best handled by a sub-project mechanism of some sort - but again that is something I am not clear on although I have heard the term mentioned in regards to git.

• .NET desktop App remembering login to a webservice

  - by pete the pagan-gerbil

  I am in the planning stages of a .NET desktop app that will communicate with a web service. The web service requires a username and password, and a common feature in this sort of app is to save the user's credentials for the next logon. I've thought of a few ways of achieving this, but I am not sure what the most secure way would be. Should it be stored encrypted in a file (and could someone nefarious copy that file to their own machine and hence logon as the original person), or in the registry somehow (I've not done any registry work before, is it secure and would it work)? Are there any other options I might not have thought of?

• Can you safely rely upon Yahoo Pipes to offload ETL for your application?

  - by Daniel DiPaolo

  Yahoo Pipes are a very intriguing choice for sort of a poor-man's server-free ETL solution, but would it be a good idea to build an application around one or many Pipes? I've really only used them for toy things here and there, with the only thing I've used longer than a week or two being one amalgamated and filtered RSS feed that I've plugged into Google Reader (which has worked great, but if it goes out for a while I wouldn't notice). So, my question is, would building an application around Yahoo Pipes be reliable (available most of the time)? Ideally it'd be something I could rely on being up 99+% of the time. It looks like the Pipes Terms of Use permit building apps around it, but I am unfamiliar with anyone building anything significant using them.

• Project Euler #163 understanding

  - by Paul

  I spent quite a long time searching for a solution to this problem. I drew tons of cross-hatched triangles, counted the triangles in simple cases, and searched for some sort of pattern. Unfortunately, I hit the wall. I'm pretty sure my programming/math skills did not meet the prereq for this problem. So I found a solution online in order to gain access to the forums. I didn't understand most of the methods at all, and some just seemed too complicated. Can anyone give me an understanding of this problem? One of the methods, found here: http://www.math.uni-bielefeld.de/~sillke/SEQUENCES/grid-triangles (Problem C) allowed for a single function to be used. How did they come up with that solution? At this point, I'd really just like to understand some of the concepts behind this interesting problem. I know looking up the solution was not part of the Euler spirit, but I'm fairly sure I would not have solved this problem anyhow.

• How can I make a UIPickerView like a UIDatePicker?

  - by iamthepiguy

  I have a custom UIViewController subclass which acts as Datasource and Delegate for a UIPickerView which I would like to serve two different purposes, as each are simple enough, and don't really warrant separate files. One operation must be as a custom picker, and this works fine. However, for the other operation, I want it to act just like a UIDatePicker. The problem is, UIDatePicker is a subclass of UIControl, not UIPickerView. Is there any sort of enum value I can set in a method (or other way) that will set the UIPickerView to act as a date picker? Or do I have to make two completely different classes and use them differently (pain in the ass)?

• Does this popup view violate HIGS?

  - by brettr

  Will using a popup view to present a comment submission form violate the HIGS? I may have one popup with selections that goes to the final popup. Two popups back to back. This is more similar to a modal type of view than an alert or action sheet as described by the HIGS: http://developer.apple.com/iphone/library/documentation/UserExperience/Conceptual/MobileHIG/ModalViews/ModalViews.html#//apple_ref/doc/uid/TP40006556-CH11-SW1 under the section 'Using Modal Views'. Basically the type of view I'm shooting for is a combination of an alert with a custom view. It's sort of a mini view since it will be centered in the middle of the screen but not take up all of the viewing area. I'm fairly sure that is a violation however, but I'm looking for a few opinions on it. I believe what needs to happen is use a modal view, which will cover the entire view.

• Correct (pretty) window redraw during the creation

  - by Coder

  Does anyone know what is a correct way to redraw window during lengthy initialization operations? Say I have HWND with NULL brush, and it does some not so quick child window initialization (Window initialization is not so quick on Vista and 7, especially on netbooks, even with threaded app). With this config window stays black for half a second on slower laptops. But if I supply window color brush, it seems that there are some sort of child controls or something that draws black squares on top of it, which also seems ugly. Even though the controls are created without WS_VISIBLE initially. Oh, the window has the WS_EX_COMPOSITED style, which should do the double buffering to avoid flicker. But it still behaves ugly. Are there any other tricks I've forgotten, missed?

• How to display Preferences in a View

  - by Sybiam

  I'm building some sort of wizard to create user accounts in Sync and Manage account. I use a ViewFlipper my activity has to be an AccountAuthenticatorActivity. That said it also means I can't inherit PreferenceActivity. So I looked up in the code of PreferenceActivity and I believe it should be possible to have a PreferenceView that inherit from ListView. The Activity part of PreferenceActivity isn't really needed as far as I know. Though the PreferenceManager is what really blocks me. private PreferenceManager onCreatePreferenceManager() { PreferenceManager preferenceManager = new PreferenceManager(this, FIRST_REQUEST_CODE); preferenceManager.setOnPreferenceTreeClickListener(this); return preferenceManager; } This function imply that we can instatiate PreferenceManager using the operator new. Apparently, the sdk hide the constructor of the PreferenceManager. I'm kind of confused. Is there a way to inflate my preferences and display them without PreferenceActivity?

• Finding cities close to one another using longitude and latitude

  - by Jamie

  Each user in my db is associated to a city (with it's longitude and latitude) How would I go about finding out which cities are close to one another? i.e. in England, Cambridge is fairly close to London. So If I have a user who lives in Cambridge. Users close to them would be users living in close surrounding cities, such as London, Hertford etc. Any ideas how I could go about this? And also, how would I define what is close? i.e. in the UK close would be much closer than if it were in the US as the US is far more spread out. Ideas and suggestions. Also, do you know any services that provide this sort of functionality? Thanks

• How do I send data from Java to Flash locally?

  - by terence

  I have a website with a Java applet and a Flash application. I want the Java applet to send data to the Flash application locally. What's the best way to do this? The data I want to send are potentially large images (possibly up to 1MB in size). This means sending a base64 string to javascript and then to Flash would probably be too cumbersome. I don't want to have to contact external servers or anything; all of it should be possible locally and offline. Is there some easy way to just send this sort of data around? If I saved the file locally first, Flash wouldn't be able to access that, would it?

• Sorting top votes in a timeframe using "Vote it up" and wordpress

  - by Mathias

  I'm building a digg-like voting site for christmas greetings. I'm using wordpress and the "Vote it up" plugin. I am having alot of troubles being able to sort the vop votes within a timeframe. You can see what I mean on this site; http://wordtaps.com/ Look at the timeframe on the top right, that's exactly what I want. The site also uses the "Vote it up" plugin along with wordpress. There are a couple of fuctions on the "vote it up" plugin page which I assume would work, but I just keep on getting errors when I try to use them as I know very little php. My site is; www.dinjulehilsen.no (it's on norwegian) All help is greatly appreciated, thank you :)

• How to perform multiple find and replace in TextMate besides macro?

  - by T1000

  I have several regular expressions to find and replace text in documents in TextMate. I would like to be able to have them run in a batch. I made a macro and it worked, but any tiny modifications to the macro means re-recording the macro. And I can't seem to modify the regex within the TextMate interface. It's read-only for some reason. Can I make it into a command? Does anyone know how? I tried to read the TextMate help about commands, but it wasn't much help. It seems I need prior knowledge of shell scripts or some sort (which I have none). Any advise in the direction would be great. Thanx in advance.

• How can one describe a rock-paper-scissors relationship between 3 items?

  - by Madara Uchiha

  Let's say I have the following structure: abstract class Hand {} class Rock extends Hand {} class Paper extends Hand {} class Scissors extends Hand {} The goal is to make a function (or a method) Hand::compareHands(Hand $hand1, Hand $hand2), which would return the winning hand in a rock-paper-scissors match. That would be very easy with a bunch of ifs, but the point is to have a more robust structure, that's relying on polymorphism rather than on procedural code. P.S. this is done in actual production code, if someone is asking. This isn't some sort of challenge or homework. (It's not really rock-paper-scissors, but you get the point).

• ASP.Net Reportviewer in folder not working

  - by Bruce

  We can run the ReportViewer in a ASP.Net Web App project that is off the root OK so localhost/test/report.aspx works. It's running as a Client Report. But if we move the application up another level the report stops working so localhost/testfolder/test/test.aspx. When the report fails it has no data to display and none of the images are loading. Info: We are bind the report in code and sort out the Report.LocalReport.ReportPath to the correct path. Can't help thinking there is a setting wrong, but stumped at the moment!

• DB2 Select - Replace STATES with two character code

  - by user2528724

  I have a Users Table where it stores city, state and country along with other Users attributes. The states are stored as California, Alabama and so forth. Now I want to retrieve the user information for certain records but the state should get translated to two digit code. Say 'California' should be 'CA'. How should I go about doing this. I was thinking to create a mapping table for state names with there abbreviation and then use some sort of replace function to do it. Any ideas ?

• Order a sentence alphabetically and count the number of times each words appears and print in a table

  - by JaAnTr

  I am struggling with the print in a table part of the question. So far I have managed to order the user inputted sentence alphabetically and count the number of times each word occurs. Here is the code: thestring = (raw_input()) sentence = thestring.split(" ") sentence.sort() count = {} for word in thestring.split(): try: count[word] += 1 except KeyError: count[word] = 1 print sentence print count And when I run the code I get this: ['apple', 'apple', 'banana', 'mango', 'orange', 'pear', 'pear', 'strawberry'] {'apple': 2, 'pear': 2, 'strawberry': 1, 'mango': 1, 'orange': 1, 'banana': 1} However, ideally I want it printed in a table that looks something like: apple.....|.....2 banana....|.....1 mango.....|.....1 orange....|.....1 pear......|.....2 strawberry|.....1 Thanks for any help!

• Finding shared list IDs in a MySQL table using bitwise operands

  - by landons

  I want to find items in common from the "following_list" column in a table of users: +----+--------------------+-------------------------------------+ | id | name | following_list | +----+--------------------+-------------------------------------+ | 9 | User 1 | 26,6,12,10,21,24,19,16 | | 10 | User 2 | 21,24 | | 12 | User 3 | 9,20,21,26,30 | | 16 | User 4 | 6,52,9,10 | | 19 | User 5 | 9,10,6,24 | | 21 | User 6 | 9,10,6,12 | | 24 | User 7 | 9,10,6 | | 46 | User 8 | 45 | | 52 | User 9 | 10,12,16,21,19,20,18,17,23,25,24,22 | +----+--------------------+-------------------------------------+ I was hoping to be able to sort by the number of matches for a given user id. For example, I want to match all users except #9 against #9 to see which of the IDs in the "following_list" column they have in common. I found a way of doing this through the "SET" datatype and some bit trickery: http://dev.mysql.com/tech-resources/articles/mysql-set-datatype.html#bits However, I need to do this on an arbitrary list of IDs. I was hoping this could be done entirely through the database, but this is a little out of my league. Any bit gurus out there? Thanks, Landon

• Enums With Default Throw Clause?

  - by Tom Tresansky

  I noticed the following in the Java Language spec in the section on enumerations here: link switch(this) { case PLUS: return x + y; case MINUS: return x - y; case TIMES: return x * y; case DIVIDE: return x / y; } throw new AssertionError("Unknown op: " + this); However, looking at the switch statement definition section, I didn't notice this particular syntax (the associated throw statement) anywhere. Can I use this sort of "default case is throw an exception" syntactic sugar outside of enum definitions? Does it have any special name? Is this considered a good/bad practice for short-cutting this behavior of "anything not in the list throws an exception"?
