• How to save video from a url to disk, also how to begin playback after some buffering?

  - by Shizam

  First question is, given a url to an mp4 video, how can I save that file to disk? The followup to that is while its saving, can I begin playback after its buffered some of the video to disk or do I have to wait for the entire file to be written and then: MPMoviePlayerController* theMovie=[[MPMoviePlayerController alloc] initWithContentURL:theURL]; using the path to the local file. Thanks, Sam

• Which format is best to use for high quality online audio and video?

  - by Mr.K

  Hi, I'm currently creating a site for a musician. They are wanting to include the best quality video and audio files possible. After a bit of research I'm thinking: FLAC is the best option for audio. FLV or MPEG-4 is best for video. Can anyone in the know confirm or correct this? Thanks

• Why .data() function of jQuery is better to prevent memory leaks?

  - by burak ozdogan

  Hi, Regarding to jQuery utility function jQuery.data() the online documentation says: "The jQuery.data() method allows us to attach data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks. " Why to use: document.body.foo = 52; can result a memory leak -or in what conditions- so that I should use jQuery.data(document.body, 'foo', 52); Should I ALWAYS prefer .data() instead of using expandos in any case? (I would appreciate if you can provide an example to compare the differences) Thanks, burak ozdogan

• Is there a way that I can force mod_perl to re-use buffer memory?

  - by Pavel Georgiev

  Hi, I have a Perl script running in mod_perl that needs to write a large amount of data to the client, possibly over a long period. The behavior that I observe is that once I print and flush something, the buffer memory is not reclaimed even though I rflush (I know this can't be reclaimed back by the OS). Is that how mod_perl operates and is there a way that I can force it to periodically free the buffer memory, so that I can use that for new buffers instead of taking more from the OS?

• SQL Server 2008 takes up a lot of memory?

  - by Ahmed Said

  I am conducting stress tests on my database, which is hosted on SQL Server 2008 64-bit running on a 64-bit machine with 10 GB of RAM. I have 400 threads. Each thread queries the database every second, but the query time does not take time, as the SQL profiler says that, but after 18 hours SQL Server uses up 7.2 GB of RAM and 7.2 GB of virtual memory. Is this normal behavior? How can I adjust SQL Server to clean up unused memory?

• How to create a named temporary file in memory?

  - by conradlee

  I would like to use Python's tempfile module to create a temporary file that I will use for communication between processes (use of pipes is awkward). The documentation I've linked to above shows two functions that almost do what I want: tempfile.NamedTemporaryFile # For creating named tempfiles tempfile.SpooledTemporaryFile # For creating tempfiles in memory but actually I want a tempfile that is both named AND in memory. Any ideas?

• Why is NULL/0 an illegal memory location for an object?

  - by aioobe

  I understand the purpose of the NULL constant in C/C++, and I understand that it needs to be represented some way internally. My question is: Is there some fundamental reason why the 0-address would be an invalid memory-location for an object in C/C++? Or are we in theory "wasting" one byte of memory due to this reservation?

• Starting a C++ project. Should I worry about freeing dynamic allocated memory?

  - by Luca Matteis

  I am pretty proficient with C, and freeing memory in C is a must. However, I'm starting a new C++ project, and I've heard some things about how you don't need to free memory using shared pointers and other things. Where should I read about this? Is this a valuable replacement for proper delete C++ functionality? How does it work?
