I've developed an equation parser using a simple stack algorithm that will handle binary (+, -, |, &, *, /, etc) operators, unary (!) operators, and parenthesis. Using this method, however, leaves me with everything having the same precedence - it's evaluated left to right regardless of operator, although precedence ca...

XP Pro is definitely better, unless you have a really beefy Mac. Regarding your other question, no there are no pitfalls, other than performance.

It depends on how "general" you want it to be. If you want it to be really really general such as be able to parse mathematical functions as well like sin(4+5)*cos(7^3) you will probably need a In which, I do not think that a complete implementation is proper to be pasted here.

It would help if you could describe the grammar you are currently using to parse. Sounds like the problem might lie there!

@Creighton: In Haskell there is a library function called : ``` prouduct list = foldr 1 (*) list ``` or simply: ``` product = foldr 1 (*) ``` so the "idiomatic" factorial ``` fac n = foldr 1 (*) [1..n] ``` would simply be ``` fac n = product [1..n] ```

I would look into [DeltaXML](http://www.deltaxml.com/). It seems to have the features you're looking for. They even have a guide on [how to compare schemas](http://www.deltaxml.com/dxml/library/how-to-compare-schemas.html).

[Ross has the right idea](https://stackoverflow.com/questions/28395/passing-post-values-with-curl#28411) for POSTing the usual parameter/value format to a url.

I am charged with designing a web application that displays very large geographical data. And one of the requirements is that it should be optimized so the PC still on dial-ups common in the suburbs of my country could use it as well. Now I am permitted to use Flash and/or Silverlight if that will help with the limite...

I don't think you'll find Flash or Silverlight is going to help too much for this application. Either way you're going to be utilizing tiled images and the images are going to be the same size in both scenarios. Using Flash or Silverlight may allow you to add some neat animations to the application but anything you g...

Is something like [Gears](http://gears.google.com/) acceptable? This will let you store data locally to limit re-requests. I would also stay away from flash and Silverlight and go straight to javascript/AJAX. jQuery is a ton-O-fun.

Since this is a development environment, I agree with Greg, just use trial and error. It's not that crucial to get it perfectly right. But if you do a lot of work in the VM, why not give it at least half of the 2GB?

You should probably raise an exception if it gets to that last `return 0` line --when a hash collision happens. I do have a question though: you are doing a total ordering on the hash's, which I guess is fine, but shouldn't some function be passed to it to define a Lexicographical order? ``` int h1 = System.identityHa...

@ebel > thinking about it, you have 64 bit representing a number greater than 2^64 (double.maxvalue), so inaccuracy is expected. 2^64 is not the maximum value of a double. 2^64 is the number of unique values that a double (or any other 64-bit type) can hold. `Double.MaxValue` is equal to 1.79769313486232e308.

I develop on my Macbook (not pro) using VMWare Fusion and WinXP. For the most part, it is a very good experience. I assign 1GB of memory, out of my 4GB, to the VM and its pretty speedy.

An alternative to making a template is to evolve one by gradually generalising your current project's Ant script so that there are fewer changes to make the next time you copy it for use on a new project. There are several things you can do. Use ${ant.project.name} in file names, so you only have to mention your appli...

I've been using StructureMap recently and have enjoyed the experience thoroughly. However, I can see how one can easily get carried away with interfacing everything out and end up with classes that take in a boatload of interfaces into their constructors. Even though that really isn't a huge problem when you're using...
