detection

问题 On a PHP upload, I'm trying to validate the MIME Type of the files being uploaded to match a valid set of MIME types for the application. When attempting to use the fileinfo() to determine the MIME type of an Office 2007 file it is NOT detecting as their appropriate MIME Types. Instead the MIME type response is "application/zip" Office Document MIME types: http://filext.com/faq/office_mime_types.php Example PHP Code: $oFileInfo = new finfo( FILEINFO_MIME_TYPE ); $sMimeType = $oFileInfo ->

问题 I started to write my own image host but I have a little problem: I want to display an HTML page if you directly view the link (eg. Domain.com/img/123) via the browser, and an image if you embed the link via <img src="Domain.com/img/123"> to faciliate the use. Is it possible to detect whether the link is directly viewed or the link is embedded with PHP? 回答1: You can use a htaccess file for this purpose: When the browser loads an embedded image, he already knows the format to expect, so he

问题 I'm using CMake as a build system for my code, which involves CUDA. I was thinking of automating the task of deciding which compute_XX and arch_XX I need to to pass to my nvcc in order to compile for the GPU(s) on my current machine. Is there a way to do this: With the NVIDIA GPU deployment kit? Without the NVIDIA GPU deployment kit? Does CMake's FindCUDA help you in determining the values for these switches? 回答1: My strategy has been to compile and run a bash script that probes the card and

问题 How can I check for duplicate email addresses in PHP , with the possibility of Gmail's automated labeler and punctuation in mind? For example, I want these addressed to be detected as duplicates: username@gmail.com user.name@gmail.com username+label@gmail.com user.name+label@gmail.com Despite what Daniel A.

问题 I need to find the architecture type of a CPU. I do not have access to /proc/cpuinfo, as the machine is running syslinux. I know there is a way to do it with inline ASM, however I believe my syntax is incorrect as my variable iedx is not being set properly. I'm drudging along with ASM, and by no means an expert. If anyone has any tips or can point me in the right direction, I would be much obliged. static int is64Bit(void) { int iedx = 0; asm("mov %eax, 0x80000001"); asm("cpuid"); asm("mov %0

问题 How do I detect what language a text is written in using NLTK? The examples I've seen use nltk.detect , but when I've installed it on my mac, I cannot find this package. 回答1: Have you come across the following code snippet? english_vocab = set(w.lower() for w in nltk.corpus.words.words()) text_vocab = set(w.lower() for w in text if w.lower().isalpha()) unusual = text_vocab.difference(english_vocab) from http://groups.google.com/group/nltk-users/browse_thread/thread/a5f52af2cbc4cfeb?pli=1&safe

问题 Is this the proper way to detect which device a user is running? NSString *currentModel = [[UIDevice currentDevice] model]; if ([currentModel isEqualToString:@"iPhone"]) { // The user is running on iPhone so allow Call, Camera, etc. } else { // The user is running on a different device (iPod / iPad / iPhone Simulator) disallow Call. } 回答1: It is not a general solution but Apple in many cases provides API calls to check wether specific feature is supported or not. Examples could be:
