Keynote: Coding in 3D: How to Code Like a Girl - Sara Chipps, Director of Public Q&A at Stack Overflow & Ellie Galloway, Jewelbots
Speakers: Sara Chipps, Ellie Galloway
A
Alright
I'm
here
to
waste
your
time
for
a
few
minutes,
the
four
I
introduce
to
you,
the
real
star,
and
so
my
name
is
Sarah.
I
work
in
a
company
called
stackoverflow.
If
you've
ever
heard
of
it,
my
favorite
band
is
Hanson
and
my
favorite
color
is
royal.
Blue
I
knew
those
really
important
to
all
of
you
here.
A
Okay,
so
I
am
part
of
the
generation
of
folks
that
became
coders
because
we
didn't
have
friends
when
we
were
little
so
I
was
11
when
I
started
coding
in
the
early
90s
I
started
doing
it.
I
was
a
home
school
kid
and
I
found
out
that
you
could
make
friends
through
your
computer
and
I
thought
that
would
be
really
fun.
I
went
to
high
school
and
I
took
a
C++
class
and
I
was
like
this
is
really
neat.
I.
A
Think,
like
this
I
want
to
do
this
always
and
then
I
ended
up
studying
computer
science
at
Penn
State,
and
then
it's
been
almost
20
years
since
then,
as
a
individual
contributor
and
a
manager
after
I
sold
out
so
I
started.
Talking
to
you
know
when
I
started
in
this
field,
I
started
looking
around
and
I
was
like
wow
there's,
not
a
lot
of
people.
A
That
look
like
me,
and
this
seems
to
be
a
fairly
homogeneous
group,
and
so
I
started
talking
to
folks
that
I
coded
with
my
male
peers
about
why
they
started
coding
and
I
heard
from
them
that
usually
around
the
middle
school
age,
they
discovered
something
like
a
game
or
an
open
or
a
community
that
got
them
really
excited
and
they
were
like
awesome.
When
I
grow
up
I'm
going
to
be
a
game
developer,
and
then
they
found
out
that
game
developers
don't
make
any
money,
so
they
decided
to
write
JavaScript,
and
here
they
are
now.
A
So
we
started
thinking
about
ways
that
we
could
reach
girls
and
female,
identifying
folks,
as
with
products
that
are
a
little
more
feminine
and
exciting
for
that
group,
and
everyone
here
knows
how
important
it
is
to
get
kids
coding
for
lots
of
different
reasons.
I
really
love
this
stat
of
thinking
of
the
jobs
that
don't
exist
yet
that
kids
need
to
learn
about
what
they're
going
to
be
doing.
A
So
in
2015
we
did
a
Kickstarter
for
jewel
baths.
Jewel
bots
are
smart
friendship,
bracelets
that
light
up
when
your
friends
are
nearby
and
you
can
code
in
their
open
source,
we
shipped
over
10,000
robots
to
over
30
countries
around
the
world.
We
started
getting
feedback
about
our
products
and
one
thing
we
heard
from
parents
that
I
didn't
it
turns
out.
I,
don't
have
kids
but
I,
know
lots
about
kids.
A
Ask
me
any
time
they
I
heard
about
the
plastic
box
that
they
keep
in
their
rooms,
where
the
toys
go,
that
kids
play
with
then
kind
of
get
over
it,
and
it
goes
in
their
box
of
plastic
and
I
heard
from
parents
that
kids
enjoy
jailbot's
they.
But
you
know,
with
short
attention
spans
and
the
desire
for
new
things.
All
the
time
was
there
something
that
we
could
do.
That
would
be
new
and
interesting
often
so
we
started
working
on
science
kits.
A
This
is
one
thing
that
you
might
notice
is
that
when
boys,
when
boys
create,
we
call
it
building
and
when
girls
create,
we
call
it
crafting.
Really
it's
just
the
same
thing:
it's
making
stuff
and
in
the
world
of
crafting
there
are
a
ton
of
concepts
that
are
science
focused
and
amazing,
and
so
we
started
building
science
kits
that
have
a
lower
price
point
and
allow
kids
to
build
using
their
imagination
and
learn
about
interesting
concepts
like
geology
and
chemistry.
A
So
today,
so
we've
been
shipping,
those
for
a
little
while
we've
been
getting
great
feedback
so
far
and
people
have
been
making
awesome
stuff.
Today,
you're
gonna
see
le
demo
a
kit
that
isn't
even
on
sale.
Yet
if
you
go
to
Joel
BOTS
comm
forward,
slash
node
interactive,
although
a
case
all
one
word,
you
can
see
the
hello
world
LEDs,
which
is
a
kit
that
incorporates
Arduino
and
light
up.
Leds
kids
can
make
awesome
badges
for
their
backpacks
or
their
t-shirts,
but
I'm
gonna
stop
going
on
because
I'm,
an
adult
and
adults
are
boring.
A
A
One
needs
part
of
this
I
think
is
that
her
dad
who's
here
today
was
the
person
who
coached
me
through
my
first
open-source
pull
request.
So
it
was
really
neat
for
it
to
come
full
circle
and
now
I
get
to
work
with
his
daughter.
So
I'm
super
pleased
to
introduce
you
to
Ellie
Galloway
who's,
going
to
talk
to
you
about
and
do
some
the
first-person
here
with
guts
to
do
some
live
coding
on
stage
super
happy
to
introduce
Ellie
Galloway
he's
going
to
talk
more
about
building
the
tool.
Bots,
hello.
B
My
name
is
Ellie
Galloway
I'm,
a
Joel
Watts
ambassador
and
have
been
for
a
couple
years
now,
I'm
going
to
be
covering
a
few
things
today,
and
that
will
be
my
story,
which
is
not
very
long,
but
it's
very
special
to
me,
I'm,
going
to
show
you
how
I
make
my
badge,
which
I
will
explain
soon.
What
that
is,
I'm
gonna
show
you
how
I
cone
my
badge,
which
is
a
live
coding,
which
is
my
favorite
part,
and
then
women
in
coding,
history
and
importance.
B
B
B
So
I
started
to
get
pretty
curious
on
what
all
those
numbers
and
stuff
meant,
and
so
I
asked
him
about
it
and
he
started
to
teach
me
through
games
like
unity,
coding
for
Minecraft
and
different
stuff,
like
that,
he
showed
me
Joule,
Watts
and
I
begged
for
one
and
eventually
he
gave
in
okay.
So
in
2018,
I
spoke
at
my
very
first
conference
at
Red
Hat,
which
was
the
best
time
of
my
life,
and
it
was
just
really
fun
to
do,
and
so
now
I'm
gonna
show
you
how
I
make
my
badge.
B
So
if
you
don't
know
what
a
badge
is,
it's
a
little
felt
thing.
So
it
has
an
Arduino
which
is
I'll,
explain
what
all
these
things
mean
in
a
bit
and
LEDs.
So
you
can
code
it
and
it
lights
up
and
makes
cool
thing,
so
people
can
play
around
with
it
and
do
different
codes.
Okay,
so
here's
what
you'll
need
in
Arduino
Jemma,
so
I
just
mentioned
that
think
of
this
as
a
computer.
So
this
is
what
you
code.
B
This
is
basically
like
a
laptop
or
something,
and
then
you'll
need
conductive
thread
and
needles,
and
what
these
do
is
it's
like
a
power
cord,
so
it
plugs
from
your
computer
and
then
the
LED
sequence
is
your
final
destination.
It's
the
outlet
just
to
make
sure
the
code
is
running
smoothly
and
you
also
need
felt
for
your
workspace.
So
anything
optional
is
decorative
different
things
like
that.
So
here's
your
plan,
you
don't
need
to
make
it
as
detailed
or
anything
I.
B
Just
did
it
because
well
I'm
speaking,
but
you
will
need
to
map
out
a
few
things
and
that
your
Jemma,
you
need
to
map
out
the
ground
or
GND,
which
is
a
metal
plate,
also
the
d1,
and
then
you
want
to
map
out
your
stitching
from
that
and
then
from
that
the
LEDs.
So
you
might
want
to
make
note
that
you
need
to
have
it
negative
and
positive
in
a
certain
order.
You
can't
just
switch
it
around.
B
That
has
a
huge
thing
to
do
with
the
code,
so
you'll
need
to
make
sure
that
the
negative
is
on
the
ground
side
and
also
make
a
note
that
if
you
cross
the
threads
it
will
lead
to
a
short-circuit
both
of
those
things
will.
So
you
just
want
to
be
careful
because
it
might
start
smoking.
Ask
me
how
I
know
so
step
two
is
cell
loops
around
the
ground,
so
the
Jandy.
B
Basically,
this
just
makes
it
so
it's
secure,
because
this
can
go
in
your
clothing
and
stuff
like
that
is
going
on
fabric,
so
you're
going
to
use
it
a
bit.
So
you
do
want
it
to
be
secure
and
secure
it's
securely
on
the
thing
that
you
want
it
to
be
on,
and
also
it's
kind
of
hard
to
actually
have
the
code
running
if
it's
barely
on
there.
For
instance,
if
we
go
back
to
the
other
example
of
the
power
cord
and
everything
you
want
to
plug
it
in
right
or
it
won't
work
in
charge.
B
B
So
what
I
mean
by
this
and
you're
just
gonna
finish
that
line
I'm,
tie
knot
and
then
you're
gonna
start
a
whole
new
stitch
and
go
from
the
d1
to
down
and
sew
across
all
the
LEDs
and
I
forgot
to
mention
you
do
want
to
sew
loops
around
the
LEDs
too.
But
after
that
just
tie
knot,
don't
cross
or
anything
cuz.
Well,
I
know
it's
okay,
lots
of
ways
you
can
mess
up
in
this.
So
then
you're
done
you
can
decorate.
If
you
want
again,
you
can
add
embroidery
floss.
You
can
take
inspiration
from
me.
B
I
embroidered
on
one
and
then
I
made
it
look
like
a
Polaroid
camera
on
the
other
and
just
have
some
fun
with
it.
Okay,
so
now
you're
done
and
I'm
gonna
show
you
how
I
code
my
badge,
but
before
we
do
that
we
are
learning
a
whole
new
language
and
I.
Don't
just
want
to
copy
things
down,
because
you
want
to
actually
learn
something
from
it
or
there's
no
point
in
doing
it
so
I'm
going
to
translate
all
these
things
and
make
it
easy
to
remember
so.
Turning
on
and
off
is
high
and
low.
B
Basically,
the
LED
voltage
would
be
higher.
So
that's
how
you
know
high,
because
it's
brighter
and
then
a
lower
boat
voltage
would
be
dimmer
or
completely
off
then
starting
off
the
kid.
This
is
a
fun
one.
I
did
digital
right
because
you're
digitally
riding
I
thought
that
was
funny.
So
now
we're
stating
the
LED
as
pin
mode
I,
think
of
it
as
the
LED
sequence
as
a
pin
and
what
mode
you're
putting
it
on.
So
now
we
can
get
to
the
live
demo.
B
Okay,
so
now
we
are
going
to
start
at
the
beginning
and
void
setup,
so
I'm
going
to
do,
pin
mode
to
start
off
the
LED
and
I'm
going
to
do
built,
wait,
sorry,
LED
underscore
built
and
and
now
I'm
gonna
do
a
comma.
And
so
what
we
need
here
is
to
give
the
LED
output
so
I'm,
just
gonna
write
output
right
here
and
it's
as
simple
as
that.
B
Okay,
so
now
we're
gonna
go
down
here
and
I'm
going
to
basically
make
it
blinking
on
the
gemma,
so
I'm
going
to
do
digital
right
now,
I'm
going
to
do
the
same
thing:
LED,
built-in,
comma.
Okay!
So
if
we
want
to
start
it
off
I'm,
going
to
turn
it
on
so
high,
okay
and
now
I'm
going
to
delay
and
I'm
gonna
delay
this
for
500
milliseconds,
which
is
equivalent
to
a
half.
Second,
then
I'm,
going
to
do
digital
right
again,
I'm
going
to
do
LED,
built-in,
okay,
so
I'm,
just
making
sure
you're
paying
attention.
B
If
we
wanted
to
make
it
blink,
which
would
we
put
next,
would
be
Polk
high,
raise
your
hand
for
high
okay,
low,
okay,
yeah
good
you're,
paying
attention.
Okay,
so
I'm
gonna
do
low
okay,
so
now
I'm
just
gonna
delay
it
for
the
same
amount
of
time
to
make
it
even
okay.
So
now,
let's
see
how
it
works.
Let
me
find
my
plug
okay.
B
Okay
and
now
let's
go
to
women
and
code.
So
this
is
history
and
importance.
Okay,
so,
as
you
can
see
from
these
numbers,
they're
pretty
sad
like
it's
pretty
uneven
right,
I
want
to
change
that.
So
here's,
the
weird
part
you
might
be
like.
Well,
maybe
women
just
aren't
interested
in
code,
but
that's
very
far
from
the
truth.
So
when
I
was
researching,
this
topic,
I
saw
that
Ada,
Lovelace
and
Charles
Babbage
worked
together
to
create
the
very
first
computer
and
ADA
was
the
first
one
to
program
in
it.
B
So,
as
you
can
see
from
the
picture,
it's
a
pretty
old
model
like
this,
isn't
when
you
just
see
flying
around,
but
she
still
worked
with
what
she
had
and
she
programmed
it,
and
she
was
the
very
first
so
who
invented
computer
software.
So
Grace
Hopper
invented
the
very
first
system,
and
this
was
back
in
the
1950s.
She
also
worked
in
the
Navy's
Navy
and
that's
really
impressive,
because
not
a
lot
of
women
worked
in
the
Navy
back
then,
and
so
she's.
B
A
really
great
role
model
so
who
invented
the
computer,
is
telephone,
so
Ernest
Neider
Hoover
created
the
first
computerized
telephone
and
this
revolutionized
modern
technology,
and
this
was
even
back
in
the
1960s
70s.
So
why
aren't
more
women
in
code?
So
here's
what
I
found
so
they
don't
really
have
robot
toys
in
the
1950s.
B
But
this
is
kind
of
a
more
recent
thing
and
that's
when
we
see
the
decline
so
I'm
not
saying
that
these
toys
aren't
good,
because
nowadays
we
see
a
lot
of
male
programmers
and
that's
because
those
kind
of
electronic
toys
go
more
to
the
boys
aisle.
So
girls
don't
really
get
inspired
that
way
and
it
makes
it
hard.
B
For
instance,
people
wouldn't
be
interested
in
the
topic
if
they're
not
seeing
how
it
works
and
how
it's
fun
so
either
girls
had
to
do,
was
it
or
if
they
are
like
me
and
snuck
into
the
boys
out
to
get
hex
bugs
and
take
them
apart,
but
ada
lovelace,
I'm,
sorry,
Grace
Hopper
did
that
too.
She
took
apart
clocks
and
she
worked
with
them
and
now
she's
a
huge
role
model
today.
Okay,
so
why
should
women
code
first
off?
B
We
need
more
programmers,
I
didn't
how
much
more
things
we
could
get
done
faster
and
the
whole
modern
era
would
be
so
much
more
advanced.
Also,
women
can
code
just
as
well
as
males
and
more
ideas
get
spread
around
we'd
have
more
input
from
different
people
and
we'd
have
so
much
more
things
today.
So
here's
one
of
my
favorite
quotes
from
Grace
Hopper,
which
are
humans,
are
allergic
to
change.
They
love
to
say:
we've
always
done
it.
This
way,
I
tried
to
fight
that.
B
That's
why
I
have
a
clock
on
my
wall
that
runs
counterclockwise,
so
I'm
I
run
my
clock,
counterclockwise
and
I.
Hope
you
do
too.
So.
Thank
you.
Have
a
wonderful
day,
my
youtube
channel
is
Ellie
Galloway
geobox,
and
you
should
find
me
in
case
you
liked
what
you
heard,
but
other
than
that
I
hope
