identification

I want to identify my archive whether it is zip or rar . But the problem I get runtime error before I can validate my file. I want to create custom notification: public class ZipValidator { public void validate(Path pathToFile) throws IOException { try { ZipFile zipFile = new ZipFile(pathToFile.toFile()); String zipname = zipFile.getName(); } catch (InvalidZipException e) { throw new InvalidZipException("Not a zip file"); } } } At the moment I have runtime error: java.util.zip.ZipException: error in opening zip file I'd suggest to open a plain InputStream an reading the first few bytes (magic

I have the following results and as you can see the name edward has different results (null and male). This has happened with several names. edward, Gender: null james, Gender: MALE karla, Gender: null edward, Gender: MALE Additionally, how can I customize the gender dictionaries? I want to add Spanish and Chinese names. You have raised a lot of issues! 1.) Karla is not in the default gender mappings file, so that is why that's getting null 2.) If you want to make your own custom file, it should be in this format: JOHN\tMALE There should be one NAME\tGENDER entry per line The GenderAnnotator

I want to uniquely identify a machine in C. The following are sources which have serial numbers, but they aren't guaranteed to be unique, or present (like a removable HDD or network card). CPU: I'm using the cpuid instruction, however, serial number is not implemented for any processor except Pentium 3, i.e. not relevant. I can use the processor signature, but this won't be unique for every processor. HDD: ? BIOS: ? motherboard: ? MAC address: via system function calls. For all the question marks, how would I get the serial numbers in C? If you answer with a system dependent solution, please

Given an executable that is compiled from C to run on Solaris, is it possible to determine which compiler was used to compile the associated incomplete executable? I can't see anything when using either the strings or the file command, and magic doesn't seem to contain anything specific. Do compilers generally put a fingerprint in their executable output files? cheers, If the executable isn't stripped, try /usr/ccs/bin mcs-p This will usually show the compiler, linker and all the header files used Yes IDA is great for this. It uses a technology called FLIRT . PEID will do the trick. It

I'm trying to build a program that utilizes a 3x3 grid of buttons (using Java Swing), so I initialize it with a GridLayout and a loop to create the buttons: panel.setBorder(BorderFactory.createEmptyBorder(3,3,5,5)) panel.setLayout(new GridLayout(3,3,10,10)); String[] buttons = {"Top Left", "Top Middle", "Top Right", "Middle Left", "Middle", "Middle Right", "Bottom Left", "Bottom Middle", "Bottom Right"}; for(int i = 0; i < buttons.length; i++) { buttray[i] = new JButton(buttons[i]); panel.add(buttray[i]); buttray[i].addActionListener(this); } The buttons load just fine, but I do not understand
