• Determine opencore or stagefright framework for mediaplayer?

  - by user415422

  I need to determine if a mediaplayer is using the opencore media framework, so that I can disable seeking for my streams. The opencore framework appears to fail silently with seeking, which I am having a hard time believing they allowed into production, but that seems the case nonetheless. I wish it were as simple as determining their SDK version, but droid phones that have api 8 seem to use opencore still, so doesn't seem to be a good option. Any ideas?

• Will the memory rise if I loads a same URL for 1000 times in Adobe AIR?

  - by Yinan

  Hi, Here is the case: I have created a test application which simply loops to load a same url for 1000 times by using HTMLLoader class from Adobe AIR. What I found is that the memory of this app keeps rising. So is this expected? I mean it's the same URL although it get loaded for 1000 times. Does the AVM create 1000 objects behind the scene?

• What does the length attribute do when set on the @Column JPA annontation?

  - by James McMahon

  What exactly does setting the length on a column do in JPA? @Column(name = "middle_name", nullable = false, length = 32) public String getMiddleName() { return this.middleName; } I understand that you can use the annotations to generate the database schema based on the entity objects, but does length do any sort of check or truncation when persistence happens, or it solely used for schema creation? I also realize that JPA can sit on top of various implementations, the implementation I am concerned with in this case, is Hibernate.

• Dynamic ORDER BY in SQL Server

  - by BrunoLM

  I saw some topics about this, but the problem is that the solutions required a "switch case"... Like this I have a table with a lot of columns, is there a way to do a dynamic sort without the switch?

• Is it possible to determine whose code (according to `git blame`) was affected by each hunk output by `git diff`?

  - by Ben

  I have a large cross-cutting commit that I would like to split up according to the authors whose code was affected, both to increase the reviewers' familiarity with the code they're reviewing, and to divide the review burden equitably. I realize that the blame may be mixed within a given hunk, in which case it would be nice to either collect multiple reviewers or just choose the most "blameworthy" one (breaking ties arbitrarily is fine).

• #Define Compiler Directive in C#

  - by pm_2

  In C, I could declare a compiler directive as follows: #define MY_NUMBER 10 However, in C#, I only appear to be able to do this: #define MY_NUMBER Which is obviously useless in this case. Is this correct, or am I doing something wrong? If not, can anyone suggest a way of doing this, either at namespace or solution level? I thought of maybe creating a static class, but that seems to be overkill for one value.

  Wikipedia defines a 'typical' ETL cycle as : Cycle initiation Build reference data Extract (from sources) Validate Transform (clean, apply business rules, check for data integrity, create aggregates or disaggregates) Stage (load into staging tables, if used) Audit reports (for example, on compliance with business rules. Also, in case of failure, helps to diagnose/repair) Publish (to target tables) Archive Clean up ..What is meant by 'Build reference data'?

• Instantiating and referencing models in MVC

  - by fig-gnuton

  In MVC, should each model be a globally accessible singleton accessible to any view/controller? Or should the models be singletons that are dependency injected into any component that requires them? Or should a new model instance be created for each component that needs one, in which case events would be used to propagate changes across model instances of the same class?

• JQuery addclass to another div (but not parent) if no data is found

  - by Danny

  I have this to add a class to the main table that the report is in if there is no data returned. $('#report-area table td:contains("Sorry, your search did not return any data")').parents('#reportArea').addClass('no-report-data') However, I have another div area "#report-footer" but it's not inside #report-area. I'd like to also add the .no-report-data class to "#report-footer" as well but in this case I don't think the .parents selector will work. Is there another selector I can use to do this?

• Compiling in g++ for gprof

  - by myahya

  I do not understand the documentation for gprof regarding how to compile your program for profiling with gprof. In g++, is it required to compile with the -g option (debugging information) in a addition to the -pg option or not. In each case I get different results, and I would like to see where the bottlenecks in my application are in release mode, not in debug mode, where many optimizations are left out by the compiler (e.g. inlining)

• How to make a data-bound combo box display (like a DisplayMember) a concatenated string?

  - by Ivan

  I have a first name and a surname as separate columns in a table. If I bind a combo box to a query and set DisplayMember property to "Name" then each person a table is represented in a combo box by its name. How do I show each person's full name (built from concatenating 2 columns) in a single comb box item in this case?

• Indexing one-dimensional numpy.array as matrix

  - by Alain

  I am trying to index a numpy.array with varying dimensions during runtime. To retrieve e.g. the first row of a n*m array a, you can simply do a[0,:] However, in case a happens to be a 1xn vector, this code above returns an index error: IndexError: too many indices As the code needs to be executed as efficiently as possible I don't want to introduce an if statement. Does anybody have a convenient solution that ideally doesn't involve changing any data structure types?

• Using many mutex locks

  - by hanno

  I have a large tree structure on which several threads are working at the same time. Ideally, I would like to have an individual mutex lock for each cell. I looked at the definition of pthread_mutex_t in bits/pthreadtypes.h and it is fairly short, so the memory usage should not be an issue in my case. However, is there any performance penalty when using many (let's say a few thousand) different pthread_mutex_ts for only 8 threads?

• What is the point of function pointers?

  - by gramm

  Hi, I have trouble seing the utility of the function pointers. I guess it may be useful in some cases (they exist, after all), but I can't think of a case where it's better or unavoidable to use a function pointer. Could you give some example of good use of function pointers (in C or C++)? Many thanks :)
