idk what you're doing or how much control you have over what languagues you're using but I would recommend checking out Python sometime, with an eye toward numpy. That's actually why I ended up learning the language in the first place (I can't stand MATLAB)

I only really figured out where I was going wrong in my problem yesterday by printing a bunch of stuff at various points in the function. Which is kind of the same but just a giant pain in the ass.

Not that the tools don't exist. They are just hard to setup, learn, and use. At least as I remember them: I haven't done C++ programming in years. And obviously since it's a compiled language the REPL has a compiling step. Something like this may actually be of use to you:

Yeah I can't even overcome the inertia needed to switch to Xcode and quit using Aquamacs and running my programs from the terminal. Switching to a new IDE is pretty intimidating and not worth it for any given single small project, so it keeps getting put off.

Learning an IDE will let you step through C++ like your used to with Matlab. It's worth the effort.

OK I will learn Xcode for the next assignment. Well, I have a signals test the day ater it is due. The next assignment though...I will learn Xcode

Or I guess I could quit drinking and posting on 2+2, that would probably free up some time

What ways would you guys recommend working with an XML file?

I've been working with fairly large XML data by opening it in Excel, but it has reached a point where Excel crashes when I try to open the XML file (possibly file too big?)

I'd like to run basic analysis of the data, i.e. breakdown of % of total with this attribute, etc., and would be interested in using this opportunity to new programming techniques. I've heard stuff like MySQL tossed around but am not exactly sure what it applies to.

So, about the switch(true) thing. Here's the code in question:

Code:

<?php
    $i = "";

    switch (true) { 
        case (!preg_match('([a-zA-Z].*[0-9]|[0-9].*[a-zA-Z])', $i)):
            $isvalid = false;
            break; 
        case (strlen($i) > 30): 
            $isvalid = false;
            break;               
        default: 
            $isvalid = true;
            break;
    }

    ?>

I actually told the author what I thought of it and he ultimately removed it. The response (emphasis added by me):

Quote:

Actually, from my knowledge, there's nothing bad using "switch (true)", considering for example Zend, Symfony and Laravel uses it in some occasions. It probably isn't the best in this example. I did consider leaving out the exercise because of the RegEx, but I decided to leave it. I'll consider removing it, or making it more simple.

I'm tempted to ask for some production examples.

It also irritates me because it misses the point of switch statements and has two conditions that do the exact same thing.

because we all know that ridiculous, terrible code never ends up in production?

Well, the part that raised my eyebrow is that the first company on that list develops the language in question. Paging eevee?

Actually, according to the Twitter link, foobarfighter is a core Dojo developer. So, probably Shoe's twin from Bizarro World.

He's talking about someone including jQuery in a project that's built in Dojo to do basic dom manipulation that's plainly supported in Dojo.

Shoe's position was much stronger than that. His position was, "Don't use jquery even if you're using jquery on the page, because with enough work you can find a lighter weight alternative" -- correct, shoe?

The fixed quote is more accurate. I would rather use a bunch of small components instead of 1 massive thing where I only use 10% of it most of the time. My views changed a bit on run time performance since then, but I still think it's 100% negligent to shove jquery down your user's throat when all you really need is a small cross browser dom selector. Especially when like 10 of them exist already.
