and fwiw i generally try to have only one return but to return early when i'm not doing that. i also always use else, always write tests, and always refactor into functions if it's more than a few lines and/or more than slightly complicated.

also also at work the main codebase is indented with tabs but when they started splitting stuff off into services the people rebelled and started indenting with spaces. so now my editor needs to know where it is before it decides to :set expandtab or :set noexpandtab.

ok serial posting but one more thing: the above lead to one of these fun python moments where i had some code like this:

Code:

#!/usr/bin/env python

class Parent(object):
    def method1(self):
        print "Parent.method1"
    def method2(self):
        print "Parent.method2"
    def method3(self):
        print "Parent.method3"

class Child(Parent):
    pass

c = Child()
c.method1() # prints Parent.method1
c.method3() # prints Parent.method3
c.method2() # raises AttributeError. wtf?!?

it turns out that the definition of method2 was indented with tabs while everything else was spaces, which python helpfully interprets as me starting a new block and hence not defining the class anymore. fun!

Yeah.. you have to convert tabs to spaces when programming in Python or else you go insane.

If anyone knows how to get java working in a browser on OSX (I know, a huge request), please take a look at this SE link:

http://apple.stackexchange.com/quest...es-in-terminal

Some **** about OSX is ****ing infuriating.

So apparently I'd let kyleb reformat my code any day.

Different kinds of whitespace have different purposes. Programmers should understand this. Newlines, tabs, and spaces are NOT interchangeable.

   code1

ive always done the first, but ive switched to second and code seems cleaner and easier to read

Depends but in a vacuum I prefer the first version. Main reason is probably that negation is harder to handle mentally because it's one extra step of callng our logic unit in the brain.

[I count people that use the tab key or some other key to create multiple spaces via their editor setup in the spaces camp ldo]

Here's why you should know vim/some light standardish unixoid editor...one day everything will fail miserably and you'll have to ssh into some box to fix large chunks of code and configuration and do it as fast as possible. Good luck if you've been using Eclipse or smth all your life.

Ah I see. Oracle broke it it sounds like. I didn't see that because your comment was blaming Apple, heh.

Nope. Didn't work with SE 6 checked (or pre-Oracle install), either. Same behavior. Still blaming Apple here.

If it only broke after Oracle's stuff updated, I think it's clear who's to blame?

Because yup, I just checked. I can run Cyberduck all I want, which is essential for my work as my predecessor didn't bother to get shell access for some of the sites I manage, and my prefs window looks like this:

I know I've run web applets before, too.

Sure, I'll grant you that assumption.

It was broken before I installed Oracle's SE 7. Now what?

Extra thought: The lack of a 32 bit version sounds like it could be problematic.

I said in #4914 that it didn't work pre-Oracle install. This was a problem before the beta install. I only installed SE 7 because SE 6 (the default installs that you show installed) did not work. No Java apps came up in any browser despite any number of restarts, checked boxes, or attempts to run Software Update.

Now we have a configuration control issue.

You tried something, it doesn't work, and it needs reverted before proper diagnosis can continue.

Because seriously, the process I've always used to install Java is idiot proof. The dialog pops up, it offers too install, I say yes, it installs, it works.

I have no clue how you borked it.

Just wipe it all and try again. Seriously. Maybe the install got corrupted somehow. Cosmic rays flipping a bit.

Neil, it did not work using the exact same settings you show. Do you honestly think I didn't Google for the most basic of configuration questions before attempting to install the SE 7 beta and then posting on apple.SE?

The fact that "it just works" is the whole problem here. That is my point. This would be trivially easy to revert and/or diagnose in Windows/Linux. In OSX, it's just supposed to work, and it doesn't, so where do I go for more information?
