• A Combinations of Items in Given List

  - by mecablaze

  Hello stackoverflow, I'm currently in Python land. This is what I need to do. I have already looked into the itertools library but it seems to only do permutations. I want to take an input list, like ['yahoo', 'wikipedia', 'freebase'] and generate every unique combination of one item with zero or more other items... ['yahoo', 'wikipedia', 'freebase'] ['yahoo', 'wikipedia'] ['yahoo', 'freebase'] ['wikipedia', 'freebase'] ['yahoo'] ['freebase'] ['wikipedia'] A few notes. Order does not matter and I am trying to design the method to take a list of any size. Also, is there a name for this kind of combination? Thanks for your help!

• Graphics glitches in Visual Studio 2010

  - by KolbyK

  I'm having graphics issues with Visual Studio 2010. When I open a solution only part of the UI renders. Entire sections like the solution explorer will be missing. This only happens after I've had Visual Studio running for a while and have opened/closed a variety of solutions. It "feels" like some sort of a GDI handle leak because the problem goes away once I reboot. I'm running Windows 7 Ultimate - 64 bit. I've updated my graphics drivers, installed the latest patches, etc. I can't find any postings about this on stackoverflow or doing a variety of Google searches. Any ideas?

• Makefile option/rule to handle missing/removed source files

  - by b3nj1

  http://stackoverflow.com/questions/239004/need-a-makefile-dependency-rule-that-can-handle-missing-files gives some pointers on how to handle removed source files for generating .o files. I'm using gcc/g++, so adding the -MP option when generating dependencies works great for me, until I get to the link stage with my .a file... What about updating archives/libraries when input sources go away? This works OK for me, but is there a cleaner way (ie, something as straightforward as the g++ -MP option)? #BUILD_DIR is my target directory (includes Debug/Release and target arch) #SRC_OUTS are my .o files LIBATLS_HAS = $(shell nm ${BUILD_DIR}/libatls.a | grep ${BUILD_DIR} | sed -e 's/.*(//' -e 's/).*://') LIBATLS_REMOVE = $(filter-out $(notdir ${SRC_OUTS}), ${LIBATLS_HAS}) ${BUILD_DIR}/libatls.a: ${BUILD_DIR}/libatls.a(${SRC_OUTS}) ifneq ($(strip ${LIBATLS_REMOVE}),) $(AR) -d $@ ${LIBATLS_REMOVE} endif

• Singletons vs. Application Context in Android?

  - by mschonaker

  Recalling this post enumerating several problems of using singletons and having seen several examples of Android applications using singleton pattern, I wonder if it's a good idea to use Singletons instead of single instances shared through global application state (subclassing android.os.Application and obtaining it through context.getApplication()). What advantages/drawbacks would have both mechanisms? To be honest, I expect the same answer in this post http://stackoverflow.com/questions/2709071/singleton-pattern-with-web-application-not-a-good-idea but applied to Android. Am I correct? What's different in DalvikVM otherwise? EDIT: I would like to have opinions on several aspects involved: Synchronization Reusability Testing Thanks in advance.

• In .net, how do I choose between a Decimal and a Double

  - by Ian Ringrose

  We were discussing this the other day at work and I wish there was a Stackoverflow question I would point people at so here goes.) What is the difference between a Double and a Decimal? When (in what cases) should you always use a Double? When (in what cases) should you always use a Decimal? What’s the diver factors to consider in cases that don’t fall into one of the two camps above? (There a lot of questions that overlap this question, but they tend to be asking what someone should do in a given case, not how to decide in the general case)

• Playing BG Music Across Activities in Android

  - by scarface

  Hello! First time to ask a question here at stackoverflow. Exciting! Haha. We're developing an Android game and we play some background music for our intro (we have an Intro Activity) but we want it to continue playing to the next Activity, and perhaps be able to stop or play the music again from anywhere within the application. What we're doing at the moment is play the bgm using MediaPlayer at our Intro Activity. However, we stop the music as soon as the user leaves that Activity. Do we have to use something like Services for this? Or is MediaPlayer/SoundPool enough? If anyone knows the answer, we'd gladly appreciate your sharing it with us. Thanks!

• ScrollViewr around expanders not scrolling automatically when expander is expanded - silverlight 3

  - by Sil

  I have several expanders inside a ScrollViewer in a fixed sized ChildWindow. The problem is when each expander expanded,the scroll will not scrolling down automatically and as a result,some of the items in the bottom will get hidden and we have to manually scroll down to see them. I saw some posts like the following link but I guess my situation is different because the children inside expanders will not get focused and I need to do something when the expander is expanded. http://stackoverflow.com/questions/1225318/how-can-i-make-the-silverlight-scrollviewer-scroll-to-show-a-child-control-with-f I am just wondering if there is a slution for that- and also would like to know if this problem is solved in silverlight 4. Thanks in advance for any help. Sil.

• Does anyone have an updated version of the SQLite .NET assembly, ie. SQLite 3.6.23.1 + possibly .NET

  - by Lasse V. Karlsen

  I'm at my wits end with the best .NET assembly version of SQLite, the one found at http://sqlite.phxsoftware.com. The only maintainer doesn't seem to have the time to update the library and it generally takes months, if not more, for newer versions to surface. Luckily, he has published the source code, so I'm hoping that someone else has made his/her own copy of it, and made the changes, and would be willing to share a copy. I've seen comments on the forums for the library to this effect, but sadly even the forum software seems to be grinding to a halt these days as password reminder emails seems to be lost to the big void, so I can't ask the few there that has said they have done it. So I'm here, hopefully the big userbase of StackOverflow can help. What I'm looking for: Updated with the latest changes to SQLite, ie. SQLite version 3.6.23.1 Possibly built for .NET 4.0 (I can do that if I can get a copy of working source) Does anyone have, or know of anyone, that has done this?

• Initializing new instances of a class in a loop, how can I persist an assignment to an event handler

  - by Pydroid

  This is a follow on question from http://stackoverflow.com/questions/3020960/why-is-my-prototype-function-not-returning-the-property-of-the-instance $.getJSON(myjson, function(data) { var json = data; for (i in json) { juuvies[i] = new Juuvy(i,json[i], font, keyfontsize, valfontsize, orbcol, orbkeycol, orbvalcol, paper); juuvies[i].juuv_it(); var mykey = juuvies[i].init_nodes(); juuvies[i].orb.node.onmouseover = function() { console.log(mykey);}; } }); And my init_nodes function, Juuvy.prototype.init_nodes = function() { return this.key; } At this point of time, I get only the last key in the loop, instead of a unique pass each time. Is there a way I can persist the assignment for the event handler?

• The meaning of tracking in git

  - by user273158

  In an article that has been cited in StackOverflow a few times (e.g. 1) , the author discusses the asymmetry between git push and git pull, and mentions the following: Update: Thanks to David Ongaro, who points out below that since git 1.7.4.2, the recommended value for the push.default option is upstream rather than tracking, although tracking can still be used as a deprecated synonym. The commit message that describes that change is nice, since it suggests that there is an effort underway to deprecate the term “track” in the context of setting this association with the upstream branch in a remote repository. (The totally different meanings of “track” in git branch --track and “remote-tracking branches” has long irritated me when trying to introduce git to people.) What is exactly the difference that he is referring to with: The notion of "tracking" in git branch --track The notion of "tracking" in remote-tracking branches in the last sentence?

• Flash: Correctly handling click-and-drag outside the browser?

  - by David Wolever

  What's the correct way to detect, from Flash, when someone has started a drag within the browser (eg, a MOUSE_DOWN event), dragged the mouse outside the browser window, released the button, then moved the mouse back over the browser? For example (assuming StackOverflow was a Flash application): I've tried the "obvious" thing, checking event.buttonDown in the MOUSE_MOVE handler, but even though the mouse button is up, event.buttonDown is true in step 2 (above). So, is there any other way to check the "real" status of the mouse button? Or any other way to handle this situation?

• Unique visitor counting in ASP.NET MVC

  - by Max

  I'd like to do visitor tracking similar to how stackoverflow does it.. By reading through numerous posts, I've figured out some details already: Count only 1 IP hit per 15 minutes (if anonymous) Count only 1 unique user-Login (per day?) Now that leaves the question of the real implementation.. Should I log the two factors live into a table (and increase count) | IP | timestamp | pageurl | Or do the counting AFTERWARDS (e.g. using IIS log files - which don't include the user, right? I know there're some similar posts outside, but NONE really has a great solution in my opinion yet..

• What's the best way to call jQuery scripts, in HTML/PHP template, or seperate js file?

  - by j-man86

  StackOverflow is telling me this is a subjective question, but I think it's a matter of fact! I have a number of scripts that I'm using on different parts of my site. In terms of making fewer http requests, I know it's better to combine all of these scripts into one .js file. However, isn't a waste of time for a page to call a .js full of 10 or 15 different functions when it's only using one? The other method I am using is to use PHP conditional statements... <?php if( is_page() ) { > $(document).ready(function(){ ... }); <?php } ?> What's the best method or comination of these methods?
