profile

问题 I am running the CapWMV sample application of DirectShow.NET. It is loading a very low quality profile in Capture.cs: // Windows Media Video 8 for Dial-up Modem (No audio, 56 Kbps) // READ THE README for info about using guids Guid cat = new Guid(0x6E2A6955, 0x81DF, 0x4943, 0xBA, 0x50, 0x68, 0xA9, 0x86, 0xA7, 0x08, 0xF6); The readme says if you MUST use guids, you can find them defined in %windir%\WMSysPr9.prx. But when I load another profile, if fails, presumably because I am not connecting

问题 I would like to upload my war onto two sepearet locations. For that I have defined following profile in my pom.xml; ........ <profile> <id>deployPoc</id> <activation> <activeByDefault>false</activeByDefault> </activation> <properties> <jboss.host>POC_Deploy</jboss.host> <jboss.deployDir>/storage2/home/server1/</jboss.deployDir> <jboss.deployUrl>scp://server1.com</jboss.deployUrl> </properties> <build> <plugins> <plugin> <groupId>com.atlassian.maven.plugins</groupId> <artifactId>maven-upload

问题 when comparing the operation var fat_cats = cats.slice() to var fat_cats = new Array(cats.length) the performance differences are confusing. In firefox and chrome new Array is slower (when it should be faster, it's just allocating an empty array and not doing iteration over it) Where as in IE8 new Array is faster (which is just confusing) Any explanation appreciated. benchmark 回答1: Figured it out by looking at the source code for V8's array functions. If an array has more than 1000 elements

问题 I have a case where I want to run the cobertura plugin in both the verify phase and the reporting phase. I have two profiles and they should both be running the cobertura plugin, but in profile A, I only want to create the xml/html output, but in profile B, I will be generating full site documentation that includes these results. I have cobertura configured as a plugin that runs as part of the verify phase, but if I do that, even if I run mvn verify site, the cobertura report does not appear

问题 I have two Maven profiles profile-A and profile-B. "B" should only be activated if "A" is not activated. So if I would call mvn install profile-B is executed (but not profile-A). But if I would call mvn install -Pprofile-A then only profile-A is executed (but not profile-B). Any hints how I need to write my pom.xml to achieve this? I already tried this, but it doesn't work: <profiles> <profile> <id>profile-A</id> <activation> <activeByDefault>false</activeByDefault> </activation> ... <

问题 I am developing a website and I need to build a data structure to store user profile information. Just like what we filled about our gender/age/education/etc. information for Facebook, etc. The current issues I met with are, Currently I may not consider all required user profile information from current design/development phase, how to design a extensible framework so that in the future I could extend user profile esaily? Are there any mature (open source) user profile framework to reference?

问题 I'm developing an asp.net intranet website with a ActiveDirectoryMembershipProvider and a SqlProfileProvider. One of the requirements of my website is to have a "Birthdays" page, which would require me to list all profiles and retrieving the birthday information from it. I approached the problem as follows: Invoke the Membership.GetAllUsers() static method; Iterate through the list of users and retrieve the profile from the member's user name This approach, however, failed for the following

问题 Some of the platforms that I develop on, don't have profiling tools. I am looking for suggestions/techniques that you have personally used to help you identify hotspots, without the use of a profiler. The target language is C++. I am interested in what you have personally used. 回答1: I've found the following quite useful: #ifdef PROFILING # define PROFILE_CALL(x) do{ \ const DWORD t1 = timeGetTime(); \ x; \ const DWORD t2 = timeGetTime(); \ std::cout << "Call to '" << #x << "' took " << (t2 -

问题 1) I would like to use the profiling functions in the Python C API to catch the python interpreter when it returns from specific functions. 2) I would like to pause the python interpreter, send execution back to the function that called the interpreter in my C++ program, and finally return execution to the python interpreter, starting it on the line of code after where it stopped. I would like to maintain both globals and locals between the times where execution belongs to python. Part 1 I've

问题 If my Author NSManagedObject model has a authorID attribute (determined by the server), will an NSFetchRequest perform better if the NSPredicate filters by authorID rather than the complete Author object? Let's say I'm fetching all Book NSManagedObject s by a certain author . Which predicateFormat is better? [NSPredicate predicateWithFormat:@"author = %@", anAuthor] or [NSPredicate predicateWithFormat:@"author.authorID = %@", anAuthor.authorID] What's the best way to profile this? I have Core
