    - by Vincent
    I have worked on UVA 10410 Tree Reconstruction several days. But I can't get the correct answer unitl now.

Thanks in advance.

  • How does Appcelerator Titanium Mobile Work?

    - by Darrell Brogdon
    I'm working on building an iPhone app with Titanium Mobile 1.0 and I see that it compiles down to a native iPhone binary. How does this work? Seems like it would take a lot of heavy lifting to analyze the JavaScript code and do a direct translation into Objective-C without having a subset language like 280 North's Objective-J and Cappuccino.

  • bit manipulation in java

    - by sarav
    I have a fragment of bytes in a byte[]. The total size of the array is 4 and I want to convert this into a positive long number. For example if the byte array is having four bytes 101, 110, 10, 1 then i want to get the long number represented by binary sequence 00000000 00000000 00000000 00000000 00000101 00000110 00000010 00000001 which equals 84279809 What is the efficient way to do that in Java?

    In Linux is there any way to compute the differences between two binaries (i.e., two executables)? Let me be more specific: I want to know how to compute the delta (delta difference) between two versions of an executable or application or software in Linux. For example if I have to download and install only the updated part (the delta difference between the latest version and the old version) of an existing application or binary how do I do that in Linux.

  • Disable MySQL general logging without restarting?

    - by shantanuo
    Can I disable general logging completely without restarting the server? Because, per the documentation: SET sql_log_bin = {0|1} Disables or enables binary logging for the current connection (sql_log_bin is a session variable) if the client has the SUPER privilege. The statement is refused with an error if the client does not have that privilege. Can I enable/disable general log without restarting MySQL?

  • How to use bundler gem binaries in path

    - by Sean Chambers
    I just started using bundler for gem packaging in vendor/. The problem is with certain gems (like rspec and cucumber) that have binaries. The binary path that is under my_app/vendor/gems/ruby/1.8/...cucumber-0.6.2/bin/ is not in my path, therefore when I go to run cucumber i get command cannot be found. What is the easiest way to execute the bundled gem binaries from within the app rather than adding a large number of folders to my path? Thanks

  • Is there a compiled* programming language with dynamic, maybe even weak typing?

    - by sub
    I wondered if there is a programming language which compiles to machine code/binary (not bytecode then executed by a VM, that's something completely different when considering typing) that features dynamic and/or weak typing, e.g: Think of a compiled language where: Variables don't need to be declared Variables can be created doing runtime Functions can return values of different types Questions: Is there such a programming language? (Why) not? I think that a dynamically yet strong typed, compiled language would really sense, but is it possible?
