• What does it mean to flush a socket?

  - by User4748402

  I don't really know much about sockets except how to read and write to them as if they were files. I know a little about using socket selectors. I don't get why you have to flush a socket, what's actually happening there? The bits just hang out somewhere in memory until they get pushed off? I read some things online about sockets, but it's all very abstract and high level. What's actually happening here?

• ReSharper 5 external sources in a .NET 4.0 project

  - by RasmusKL

  I've read about the ReSharper external sources feature in ReSharper 5. But when attempting to use it on a .NET 4.0 project, but my attempts to make it work / use it have failed. Whenever I attempt to navigate to "Sources from Symbol Files" - I just get the message that the symbols are not available. Are the debug symbols for .NET 4 not released yet or are they placed somewhere else? It works fine and downloads the proper symbols for .NET 3.5 projects.

• Receiving an ACTION_SEND intent from the Gallery

  - by KyleStew

  I am trying to receive an image from the Android Gallery via an ACTION_SEND intent. I have set the proper intent filters and the Gallery opens my app. Now I want to know how to get at the image data. I can't find any examples on the internet of how this is done. I figure the path is somewhere in intent.getData() but how exactly do I pull that image from the gallery?

• How can I tell what directory an imported library comes from in python?

  - by muudscope

  I'm trying to modify a python library that I downloaded and am using. But the changes I'm making aren't doing anything. So I suspect that python is importing a different copy of this library from somewhere else on the filesystem. So... When I run import foolib in python, how can I tell where on the filesystem it's getting that library from?

• Difference between INSERT INTO and INSERT ALL INTO

  - by emily soto

  While I was inserting some records in table i found that.. INSERT INTO T_CANDYBAR_DATA SELECT CONSUMER_ID,CANDYBAR_NAME,SURVEY_YEAR,GENDER,1 AS STAT_TYPE,OVERALL_RATING FROM CANDYBAR_CONSUMPTION_DATA UNION SELECT CONSUMER_ID,CANDYBAR_NAME,SURVEY_YEAR,GENDER,2 AS STAT_TYPE,NUMBER_BARS_CONSUMED FROM CANDYBAR_CONSUMPTION_DATA; 79 rows inserted. INSERT ALL INTO t_candybar_data VALUES (consumer_id,candybar_name,survey_year,gender,1,overall_rating) INTO t_candybar_data VALUES (consumer_id,candybar_name,survey_year,gender,2,number_bars_consumed) SELECT * FROM candybar_consumption_data 86 rows inserted. I have read somewhere that INSERT ALL INTO automatically unions then why those difference is showing.

• Searching subversion history (full text)

  - by rjmunro

  Is there a way to perform a full text search of a subversion repository, including all the history? For example, I've written a feature that I used somewhere, but then it wasn't needed, so I svn rm'd the files, but now I need to find it again to use it for something else. The svn log probably says something like "removed unused stuff", and there's loads of checkins like that.

• Loading material parameteres from FBX in XNA

  - by M_F

  I've got some material parameters stored in the FBX file (DiffuseFactor, ShininessExponent, SpecularFactor and others), but I can't get to them using Effect.Parameters nor BasicEffect (they've got only the basic stuff - like EmmisiveColor or alpha). I know, that I can try to write a Effect-derived class, but is there any other way? A built-in feature or maybe some half-raw parameters stored somewhere?

• session[:key] = value doesn't work

  - by Bill Leeper

  I am trying to make use of session data in my application and for some reason I don't have something setup right. The code: session[:key] = some_value Generates the following error: The error occurred while evaluating nil.[] Other controllers don't have an issue with the session, so I am guessing I missed some basic configuration thing somewhere.

• Multithreaded Applications

  - by j-t-s

  Hi All I have been reading the articles on MSDN, but my mind is dead (this usually happens when I read MSDN (No offense MSDN, but your articles confuse me at times.)), and I'm trying to do some "background work" in may app, but not sure how. It's just a single method. But the application hangs, and I have to wait up to 1 - 3 minutes for it to become ...unhanged? Are there any simple examples that are laying 'roun online somewhere that I can have a look at/play around with? Thank you all

• Implementing a 30 day time trial

  - by svintus

  Question for indie Mac developers out there: How do I implement a 30-day time trial in a non-evil fashion? Putting a counter in the prefs is not an option, since wiping prefs once a month is not a problem for an average user. Putting the counter in a hidden file somewhere sounds a bit dodgy - as a user I hate when apps sprinkle my hard drive with random files. Any ideas?

• Custom spring bean

  - by Hari

  Hi, I want to convert some of our internal API into a spring bean that we can use in other projects. This API needs some instantiation and other logic which I want to encapsulate in this bean so that we can just put the bean into our app context with necessary propoerties alone. I remember having read an article on this somewhere in the past - but cant find it now. Any pointers to something similar will be helpful

• Reading a SquashFS archive

  - by p-static

  (SquashFS is a compressed filesystem - http://en.wikipedia.org/wiki/SquashFS) I'm looking for a way to read a SquashFS filesystem from a program. So far, I've know about the in-kernel drivers for it, but I'm sure that a userspace library for it must exist somewhere. Any language would be fine, but C is preferred. Just mounting the filesystem and using it that way is technically possible, but I'd rather avoid that route because the application I'm looking at would involve working with at least a few dozen archives at any given time.

• Static member class - declare class private and class member package-private?

  - by Helper Method

  Consider you have the following class public class OuterClass { ... private static class InnerClass { int foo; int bar; } } I think I've read somewhere (but not the official Java Tutorial) that if I would declare the static member classes attributes private, the compiler had to generate some sort of accessor methods so that the outer class can actually access the static member class's (which is effectively a package-private top level class) attributes. Any ideas on that?

• How to construct a c++ fstream from a POSIX file descriptor?

  - by BD at Rivenhill

  I'm basically looking for a C++ version of fdopen(). I did a bit of research on this and it is one of those things that seems like it should be easy, but turns out to be very complicated. Am I missing something in this belief (i.e. it really is easy)? If not, is there a good library out there somewhere to handle this?
