• How do I create a "global variable" in Java such that all classes can access it?

  - by Chrystle Soh

  here's my problem: I have multiple classes that are part of the same package and they need access to a certain file path String filePath = "D:/Users/Mine/School/Java/CZ2002_Assignment/src/" Rather than declaring the same Filepath in every single class, is it possible to simply have a "global" type of variable of this FilePath so that all classes can access it and I only need to declare and update it once. Thanks

• Is there a way to catch an attempt to access a non existant property or method?

  - by Tor Valamo

  For instance this code: function stuff() { this.onlyMethod = function () { return something; } } // some error is thrown stuff().nonExistant(); Is there a way to do something like PHP's __call as a fallback from inside the object? function stuff() { this.onlyMethod = function () { return something; } this.__call__ = function (name, params) { alert(name + " can't be called."); } } // would then raise the alert "nonExistant can't be called". stuff().nonExistant();

• Using mod_negotiation to serve webp if the UA requests it.

  - by Rich Bradshaw

  Is it possible to use mod_negotiation to serve up a webp image if the browser supports it, and a jpg otherwise? For instance, if I link to an image with the path /images/test, it serves the image found at /images/test.webp if the UA knows about webp, or jpg otherwise? I've tried poking around, but it seems that the Accept headers in Chrome at least look like Accept:*/*, rather than specifying the image type. If this isn't the way to do it, has anyone got any other suggestions?

• Python : Convert from C-Char to Int

  - by cuband

  I have a string read in from a binary file that is unpacked using struct.unpack as a string of length n. Each byte in the string is a single integer (1-byte) representing 0-255. So for each character in the string I want to convert it to an integer. I can't figure out how to do this. Using ord doesn't seem to be on the right track...

• Operating System Development

  - by j-t-s

  Hi All I'm looking for any website(s) devoted and/or related to Operating System Development, and would love for you to kindly share any links you may have. I have searched myself, but keep winding up at the same old sites, and am wondering if there are others that just don't get noticed by the major search engines or something. I've put this as a community wiki, simply because I don't think it's very fair to judge an answer based on a single link. Thank you.

• How do I read and write to a file using threads in java?

  - by WarmWaffles

  I'm writing an application where I need to read blocks in from a single file, each block is roughly 512 bytes. I am also needing to write blocks simultaneously. One of the ideas I had was BlockReader implements Runnable and BlockWriter implements Runnable and BlockManager manages both the reader and writer. The problem that I am seeing with most examples that I have found was locking problems and potential deadlock situations. Any ideas how to implement this?
