TIL there is a room in a hospital in Phoenix that provides medical support for pretty much every long-distance passenger flight in the world.

TIL that the code I write now is much easier to maintain than the code that I wrote 4+ years ago.

Good for you! I have a few things like that, and others that still are so "spaghetti like" that I hesitate to touch them, even for the purposes of refactoring. (Just finished on one of those, basically "grep mysql" and once that was all changed to "mysqli" just test it and let it go live 😉

(Of course, even THAT isn't as bad as yesterday, in which I had to perform the same edit on the same line of 5 dozen different files that could've all been the same file with a variable switch ... fortunately that was someone else who wrote that stuff .... )

Yeah...had to change one API's output and wasn't sure what files I might have to touch. Turned out the entire fix took place in one method that was only a few lines long -- if you consider the array definition that took about 20 editor lines to be one line. 🙂

// links is now an array of all a tags that are children to deskTopcontrols

Much cleaner

Today I learned, don't drop strange looking objects in work, they are normally fragile and are worth a lot of money 😃

Noice 😉

To make matters a tad worse, the 50+ files were in ColdFusion and over 6 years old on a site that gets nearly no traffic. (Of course, now that it's fixed maybe it'll get more?)

Today I learned to use dmd.

Fun isn't it? 😛

Hey, I'm the one who ran into a wall with his face.

TIL our new kitten can escape a closed and locked cat cage. Still haven't learned how.

[NogDog]

TIL how to create a Rails rake task.

Today I learned Ethan Brown is a clever man

Today I learned how to "monkey patch" a built-in class in Ruby.

[~/projects/railsapp]$ irb
2.2.1 :001 > foo = 0.66666666666
 => 0.66666666666
2.2.1 :002 > bar = 0.66666666667
 => 0.66666666667
2.2.1 :003 > foo == bar
 => false
2.2.1 :004 > class Float
2.2.1 :005?>   def ==(other)
2.2.1 :006?>     return (self - other).abs < 0.000000005
2.2.1 :007?>     end
2.2.1 :008?>   end
 => :==
2.2.1 :009 > foo == bar
 => true

Today I learned switch case in JavaScript is more or less the same as php

[cluelessPHP]

Today I learned if I open my window and place my laptop on the window shelf I can pick up the free wifi signal outside 😃

[cluelessPHP]

Today I learned

<script type="text/javascript"> 
<!--

var findlength = "cake is not a lie"; 

var counter = findlength.length;
 var validInput = 40;


 result = (counter > validInput) ? true : false; 

 if(result === true)
 {
	console.log("clever boy");
 }
 else if(result === false) 
 {
	console.log("ben dan laowai");
 }

 console.log(counter);

//--> 
</script> 

I have a feeling this might have been one of the most important things I've learned to date

TIL that in Lua the most efficient way to determine the number of elements in an arbitrary table (that's array to you and me) is

local count = 0
for _ in pairs(thetable) do count=count+1 end

And the length [font=monospace]#[/font] operator is only well-defined if the table's keys are consecutive integers starting from 1, ignoring (and not counting) non-integer-keyed entries.

[cluelessPHP]

Today I learned you can try {} catch in JavaScript

[cluelessPHP]

Today I learnt how to "pick up a signal" and tether my laptop to it via mobile phone :o

More about Lua.
While you can use tables as keys in other tables, tables have object identity, so doing so causes awkwardnesses.

local tab = {}

tab[{"a", "b", "c"}] = "foo"
tab[{"a", "b", "c"}] = "bar"

Now [font=monospace]tab[/font] contains two elements, which you can iterate over (while of course the length operator reports zero).
Further,

tab[{"a", "b", "c"}] == "foo"

would evaluate to [font=monospace]false[/font] and

print(tab[{"a", "b", "c"}])

outputs the string "[font=monospace]nil[/font]".

That's because each of those four "abc" tables is a different entity.

So if you want to use tables as keys, you would need to store them somewhere in order to refer to them as needed. Probably store them in another table. With a value-type key so that you can look up specific members. At which point you'd wonder why you didn't use the value-type key in the first place.
