[ "Using javax.sound.sampled with openjdk-7 on Raspi", "I'm having big problems getting good sound out of my Raspi using Java.\n\nI want to write an little AirPlay Client to a media server I wrote in Java. I started with using the Player Class from javazoom (http://www.javazoom.net/javalayer/docs/docs1.0/javazoom/jl/player/package-summary.html). Which gave me a not really choppy but somehow distorted and slower than normal playback of an mp3 file I streamed over to the Raspi.\n\nMy first idea was, that maybe the decoding of an mp3 was a bit too much for the Raspi, especially since overclocking helped a little.\nSo now I'm converting the mp3 to a wav file on the server and then stream it to the Raspi playing it with the javax.sound.sampled.* stuff. Yet, no improvement :|\n\nHas anybody some experience with playing soundFiles from Java on an Raspi? Any advice helps!\n\nThanks, Stefan" ]

[ "Is it possible to have a specific merge strategy just for 'git pull'", "The project I'm on has two branches, ostensibly named STABLE and DEV.\n\nThere's been some divergence in a core part of project between the two branches so when merging from Stable to DEV, we're using the ours merge strategy.\n\nHowever, when pulling from Remote to DEV, we don't want to use the ours merge strategy, otherwise we'll not get the changes we need (if I understand merge strategies correctly)\n\nSo I guess the question is: is it possible to use one merge strategy when merging branches, and a different strategy when pulling from remote.\n\nOr is my understanding of merge strategies all wrong?" ]

However every time I change a single line of code by running xbuild OpenTK.sln /p:Configuration=Debug it kicks off a rebuild all which takes about an hour to compile.\n\nI can't find a switch anywhere in the command-line help, but wondered if anyone knew how to make xbuild only compile the modified files?

[ "Airplaying video from url to ATV using lots of battery on iphone", "I am writing an app that plays a url using MPMoviePlayerController. The app works in the background and using airplay also works with an ATV, macmini using airserver and XBMC. The url is to a movie file on the local network. The way I understand is that the phone doesn't do any heavy lifting but merely passes the url to the apple tv and as long as the url points to media that the AppleTV supports then it will play.\n\nThe problem I am having is that the apple TV must be aggressively pinging the iphone and keeping the wifi active since the battery life is hit really hard. Playing an average sized movie knocks the battery life by about 2/3 on an IPhone 3GS and 1/2 on an IPhone 4S. \n\nIf I am playing on the mac mini using air server then the battery life on the phone reduces at the same rate as if the phone was backgrounded and not playing anything. I noticed that if I stop the wifi on the iphone then the movie will keep playing on the mac mini but stops within about 30s on the ATV. I am guessing the ATV keeps pushing out an event saying that it is playing and if it doesn't receive an OK in return then it stops playing.\n\nIs there something I am doing wrong? Have other people experienced the same battery drain using airplay from their phone? I have tried someone else's app and it also did the same." ]
