All the GoogleIO easter eggs (and how did I get them).
Unveiling the secrets behind GoogleIO'13's easter eggs, this post narrates the author's process of deciphering the hidden codes using coding skills and a Chrome extension. It provides a guide to accessing these easter eggs, showcasing the clever interplay between technology, gaming, and curiosity.
UPDATE : After the Google IO'13 started, the experiment has been moved to a new home : https://developers.google.com/events/io/experiment
If you just want the GoogleIO'13 easter eggs codes, jump directly to the bottom if this post. If you're interested in how I got'em all, read along.
So, the main codebase is located in the /js/app.min.js of the site. But it's compiled and pretty much unreadable. Luckily, I have Sight, a Chrome extension that indents/prettifies the code. But still, it's still not readable.
I had to browse through the code to find some telltale signs, and what do you know, I find this :
ww.mode.register('home', ww.mode.HomeMode, null)
ww.mode.register('cat', ww.mode.CatMode, 231, 8)
var isAndroid = navigator.userAgent.match(/Android/)
isAndroid || ww.mode.register('space', ww.mode.SpaceMode, 42, 8)
ww.mode.register('pong', ww.mode.PongMode, 129, 8)
ww.mode.register('bacon', ww.mode.BaconMode, 144, 8)
ww.mode.register('simone', ww.mode.SimoneMode, 211, 8)
ww.mode.register('eightbit', ww.mode.EightBitMode, 83, 8)
ww.util.getAudioContextConstructor() &&
(ww.mode.register('song', ww.mode.SongMode, 219, 8),
ww.mode.register('synth', ww.mode.SynthMode, 136, 8))
ww.mode.register('ascii', ww.mode.AsciiMode, 127, 8)
ww.mode.register('bowling', ww.mode.BowlingMode, 117, 8)
ww.mode.register('rocket', ww.mode.RocketMode, 69, 8)
ww.mode.register('burger', ww.mode.BurgerMode, 57, 8)
It doesn't say much, but at least there is some chance I could decipher this mess.
Then I searched for the ww.mode.register function, which is :
ww.mode.register = function (a, b, c, d) {
ww.mode.modes[a] = {
klass: b,
pattern: c,
len: d,
}
}
Klass, Pattern, and len. I looked for where is klass (easier and distinguishable) is called/located through the code, and I found this snippet, which unlocks pretty much everything :
for (c in a)
a.hasOwnProperty(c) &&
a[c].pattern &&
((d = a[c]),
(b[c] = {
klass: d.klass,
binaryPattern: ww.util.pad(d.pattern.toString(2), d.len),
}))
Three things : ww.util.pad, d.pattern, and d.len.
ww.util.pad pretty much does an d.len-bit binary conversion (code below), in our case, always 8bit, and d.pattern is the c param in the ww.mode.register function,
ww.util.pad = function (a, b) {
for (var c = '' + a; c.length < b; ) c = '0' + c
return c
}
Now everything is crystal clear - All I had to do is to rewrite the ww.util.pad as a standalone function :
function io(a, b) {
for (var c = '' + a; c.length < b; ) c = '0' + c
return c
}
And then, it's just a matter of calling io() with the different patterns converted to binary:
var a = 219
io(a.toString(2), 8) //outputs 11011011, which converts to IIOIIOII
