00:00:00.500 --> 00:00:02.000 D:vertical A:start
The Web is always changing
2
00:00:02.500 --> 00:00:04.300
and the way we access it is changing
3
00:00:05.000 --> 00:00:07.000
The source of that change is <c.highlight>you</c>
4
00:00:07.100 --> 00:00:11.000
Developers all around the world who are using our tools to create great new things
5
00:00:11.200 --> 00:00:13.200
and with so many tools, the sky is the limit
6
00:00:14.500 --> 00:00:16.500
But it cant happen without you and your ideas
7
00:00:17.500 --> 00:00:18.700
We want to know you better
8
00:00:18.700 --> 00:00:21.000
so we created a new place just for that
9
00:00:21.000 --> 00:00:22.000
to hear from <u>you</u>
10
00:00:22.500 --> 00:00:25.000
We want to hear what inspires you as a developer
11
00:00:25.500 --> 00:00:27.000
and how we can help.
12
00:00:27.000 --> 00:00:30.800
Here you can record a video, share stories with us and more
13
00:00:31.000 --> 00:00:34.000
Let us know what being a Google developer means to you
14
00:00:34.000 --> 00:00:38.200
and you can talk to us in person at Google Developer events all over the world.
15
00:00:38.500 --> 00:00:41.000
so we can learn how to support you better.
16
00:00:41.000 --> 00:00:44.600
Oh, btw, we also started rolling a new site for Google Developers
17
00:00:44.700 --> 00:00:49.400
Not just code but community, news, tools and other resources
18
00:00:49.400 --> 00:00:51.000
and cake
19
00:00:51.200 --> 00:00:54.000
Like any open source project it's a work in progress
20
00:00:54.100 --> 00:00:57.000
with your help it can be great
21
00:00:57.000 --> 00:01:00.000 L:12%

<p>
In March 1936, an unusual confluence of forces occurred in
Santa Clara County.
</p>
<p>
A long cold winter delayed the blossoming of the millions of
cherry, apricot, peach, and prune plum trees covering hundreds
of square miles of the Valley floor. Then, unlike many years,
the rains that followed were light and too early to knock
the blossoms from their branches.
</p>
<p>
Instead, by the billions, they all burst open at once.
Seemingly overnight, the ocean of green that was the Valley
turned into a low, soft, dizzyingly perfumed cloud of pink
and white. Uncounted bees and yellow jackets, newly born,
raced out of their hives and holes, overwhelmed by this
impossible banquet.
</p>
<p>
Then came the wind.
</p>
<p>
It roared off the Pacific Ocean, through the nearly
uninhabited passes of the Santa Cruz Mountains and then,
flattening out, poured down into the great alluvial plains
of the Valley. A tidal bore of warm air, it tore along the
columns of trees, ripped the blossoms apart and carried them
off in a fluttering flood of petals like foam rolling up a
beach.
</p>
<p>
This perfumed blizzard hit Stevens Creek Boulevard, a two-lane
road with a streetcar line down its center, that was the main
road in the West Valley. It froze traffic, as drivers found
themselves lost in a soft, muted whiteout. Only the streetcar,
its path predetermined, passed on...
