The Weird and The Wonderful

22-Jul-12 8:30

Just reading through some javascript the other day when I found this gem.

JavaScript

// Gets cursor position inside in node element.
function GetCursorPosition(node)
{
    // I have no time for Opera. What a nightmare to debug
    if (navigator.userAgent.toLowerCase().indexOf("opera") != -1) return 0;

Would now be a bad time to say that I found it here at CP? Laugh | :laugh:

+5 to the first person to correctly identify where!

Well, someone doesn't like Opera!

I wonder when this will be solved.

(Or if)

Are you talking about this[^]?

Read the article "Table Valued Parameters".

Nope, ftfy too.

You've both had it in your browsers today...

Yes, I found it.

Yep, tracks cursor position inside the textarea where i'm writing now (hm, i'm feeling watched). At first glance, seems to be responsible for checking if cursor position is inside a tag when copying and pasting code. I may be wrong, but this is what I got in 1 min or so Poke tongue | ;-P

EDIT: Now, thanks to Jochen I actually took his suggestion, so the 5 should go to him

Yep - that's exactly what it does. With the evolution of "security" in browsers, handling Paste events has become more and more painful, so much so that the only way I can reliably handle it is to watch every elephanting keystroke in order to work out when a Paste event has happened and what was Pasted.

Except that Opera totally screws it up. I gave up.

You should see the server-side comments... Blush | :O

What condition, or lack thereof, am I even testing for again???

Condensed and renamed to protect the guilty...

Public Sub TestThis(bFlag as Boolean, objVar as Object)

    If (Not bFlag) And (bFlag <> Not CBool(objVar Is Nothing)) Then
         'do some stuff
    End If
End Sub

I know the CBool is completely unneeded. But I'm having a heck of a time understanding what this little snippet was supposed to be testing for, or how it even came into existence in the first place. It seems like it would be cleaner to just test:

(Not bFlag) And Not (objVar Is Nothing)

There are actually several other instances of this kind of test that I think are just there for a confusion factor. They all follow the same basic pattern of:

(Not boolean1) And (boolean1 <> boolean_test_condition)

In order for the whole test to be True, the first Boolean must be False, so boolean test condition on the right side MUST be True. Why even bother comparing the test condition result against the first value?

(Not boolean1) And boolean_test_condition

I'm so ripping my hair out every time I have to dive into legacy code like this. Good thing it's Friday!

That's called obfuscation.
Theoretically, it could be intended (protection against reverse engineering, or just abuse of the colleagues who have to maintain that code).
But more often, it happens due to other factors. E.g. the law of thermodynamics: things get worse under pressure. Or medical conditions like hypocaffeinemia.

It's duplicated, too lazy to fix.

I think, array is a vulgar word for someone. Funny thing, I didn't understood what in the name of lord does that (variables were not descriptive about content they have) Also, funny comments! Laugh | :laugh:

I've learned that placing such a comment will make your code go to any lengths (apparently even changing variable values out-of-the-blue) to take that path...

Also, speaking of funny comments, my colleague found this little gem in a PHP script:

//Do this the old-fashioned way, i don't trust PHP's 'i++'
$i = $i + 1;

What do you have against PHP? It's soooo easy to learn and it has been used for soooo many big projects.

Andrei Straut20-Jul-12 2:57

Yes, and at the same time, it makes it awwwwwwfully easy to code badly.
You can code badly in absolutely any language, but bad code written in PHP just.has.that.special.flavor.

[rant start]
Now, assume we have some code (PHP) along the lines of:

$invoice_no = 1;

//some code

//Then someone comes who does not read docs, or has no idea that invoice_no should be an int, and does something with the following effect:
$invoice_no = $invoice_no . 'INV_123#';

//Some other code
return $invoice_no;

Now, try to do this in Java for instance:

int invoice_no = 1;
invoice_no = invoice_no + "INV_123#";
return invoice_no;

The compiler would be all over the place, screaming like a newborn baby. And that's just off the top of my head.

And speaking of compiler and autocomplete, how about contructs like:

$invoice_no = 'Whatever';

//Code

return $invoiceno; //first occurrence of $invoiceno, the IDE doesn't complain about it, is undefined, but you sucker will only know at runtime, from a !!!Notice!!!

Or that you can't really enforce a type parameter on a method (of course, there's get_class, but you'll only know about it at runtime).

Or autocomplete. I'a big fan of autocomplete. Now, I've done PHP with both Eclipse and Netbeans. Try to get autocomplete for something like:

$db = DatabaseService::getInstance();
$line = $db->getPoLineById($line_id);
$product = $db->searchProduct('id', $line->getProductId()); //This is where the magic ends. No autocomplete for 'line->'

Or debugging. var_dump, really? Now, I know there's XDebug, but try using that in a 4GB PHP project (I'm talking about a Magento website). Good luck with that.
[rant end]

Now, I do believe your remark was sarcastic. For being sarcastically funny, have a 5! Laugh | :laugh:

Thanks. Indeed I don't jump off bridges just because it's especially easy on this particular bridge or many people have done so before. Not even the lemmings really do that. Smile | :)

I have started to ignore languages which are interpreted or are advertised as being especially noob-friendly on 8 bit machines. Especially the 'noob-unfriendly' things (like type safety) usually are supposed to help you and I have no interest in learning how to bypass them or constantly discussing why it's a bad idea to bypass them.
