A
How
you
know
how
your
problem
is:
pretty
big
Broadwater,
any
water
I
think
the
hydro
is
really
big,
but
in
very
diverse
way,
there's
like
a
problem
with
problem
management
and
also
like
for
my
exploration
and
like
they're,
always
up
to
you
technical
problem
related
to
water.
Well,
the
interesting
problem
was
that
so
I
met
that
John
John
Nyquist.
He
was.
A
A
A
A
Nice
yeah,
but
like
depends
upon
the
precipitation
and
how
you
design
that
that
dreaming
each
path
like
it
could
be
very
different
but
then
actually
like
the
high
road,
is
really
long.
How
do
you
like
it
manage
that?
How
do
you
want
internet?
That's
that's!
What
she's
working
on
anywhere,
maybe
there's
specific
church
a
highway
that
yeah.
A
Then
what
he's
really
interested
in
infiltration?
So
you
want
to
have
a
good
idea
about
the
how
the
infiltration
rate
yeah
in
each
like
a
like
a
pixel
of
it
like
this
Garabedian
paradesi
line
over
became
the
value
of
infiltration
ready
to
for
a
2d
line,
yeah
at
that's,
pretty
gay
so
been,
and
then
you
can
pass
that
to
engineers
so
that
they
can
actually
design
the
system.
So
they
are
full.
B
A
You
cannot
only
that
storm
wall
say
that's
some
awkward
which
are
yet
basically
same
problem
right
then
you
know
what
you
want
to
know
how
the
infiltration
happens
yeah.
What
is
your
based
of
that?
So
that's,
that's!
Basically
the
problem.
Once
you
saw
what
I
think
so
there
were
a
bit
of
talks
about
that
how
people
are
doing
in
how
they're
coupling
with
different
physics
than
field
doing
so.
B
A
Calgary
he's
working
at
world
portion
yeah
and
now
he
gave
a
talk
at
that
watching.
That
was
really
cool
and
yeah
yeah,
so
I
think
UN
and
it's
French
I
mean
actually
they're
putting
quite
a
bit
of
money
for
Kenyan
like
there's
refugees
to
what
their
riches
in
Kenya
yeah
and
somehow
they
want
to
provide
I
need
to
produce
more
yeah,
yeah,
so
they're
developing
bottom
order,
stuff
yeah,
so
they'd
spend
a
lot
of
money
in
the
I.
Think
the
like
very
successful.
A
A
A
B
B
B
A
Something
in
that
sense
wasn't
very
exciting,
but
that
was
pretty
cool,
so
it's
not
very
like
high-tech
media,
but
that
what
I
was
a
little
bit
disappointed.
I,
think
people
in
that
group
or
kind
of
like
a
dispel
you're,
like
I,
saw,
observe
like
cutting-edge
inversion,
an
idiot
versions
all
right
those
kind
of
things,
because
that
okay,
we
could
do
very
simple
things:
yeah.
B
A
Something
useful
with
some
of
the
hypothesis
they
a
bit
yes
but
I
think
that
they
can
go
bit
more
yeah
I
mean
you
can
expect
more
because
you're
spending
fighting
for
money,
but
like
no
time
yeah
limited
time
bets,
can
three
excuse
yeah,
which
spot,
but
I
really
hope
that
I
can
see
a
little
bit
more
kind
of
complicated
or
like
more
cutting-edge
stuff.
They
can
do
yeah
extract
information.
You.
B
See
like
I'm
not
was
there
a
given
dataset,
but
something
like
that,
but
you
would
like
to
get
your
hands
on
to
show
that
which
I
want
us
to
do
79.
What
would
it
mean
like?
Well,
okay,
so
meaning
boat,
Paul's
talk
for
example,
and
it
could
be
the
nastiest.
But
like
was
there
a
given
dataset
that
you
saw
they
show
a
little
bit
of?
But
you
saw
potential
to
do
something
more.
B
A
A
A
B
A
G
A
B
That's
weirdly
related,
but
we're
keeping
money
to
radar
I'm
in
touch
with
a
number
of
people
at
the
AG,
and
that's
why
I
salute
Louise
Clark
she's,
the
one
who
sort
of
flipped
championing
this
connection
right
now
right,
but
we've
been
in
touch
with
the
AG
you
and
she
sort
of
brought
forwards
to
created
a
document
called
open
source
in
five
to
ten
years.
I
can
actually
pull
that
up
might
be
worth
you
guys,
taking
a
look
at
as
well.
B
And
rhyming
with
Joe
and
there's
a
lot
of
similarities,
I
mean
like
opening
up
datasets,
trying
to
promote
best
practices
or
that's
where
there's
stuff,
and
so
I
mean
it
was
got
significant
funding
from
NSF
and
a
few
other
places.
Whereas
what
we're
sort
of
starting
I
mean
we
don't
have
any
funding
at
the
moment.
I!
Don't
think
that
rules
that
out
down
the
road
but
we're
just
sort
of
throwing
ideas
around
this
but
anyways
we
sent
this
document
called
an
email
from
Louise
and
she
said
I'm
meeting
with
everybody
tomorrow.
B
So
we
we
toss
this
together
and
then
sent
it
to
the
rest
of
the
group
involved
so
like
Jared
peacock
who's
at
the
USGS
Leo
was
involved,
Leon,
Krishna
who's
with
Bob
spy,
and
so
just
like
sketching
out
a
few
things
that
we
sort
of
want
to
see
with
open
source
and
particularly
because,
like
the
aju
is
a
big
organization
and
if
they
decide
to
like
make
this
a
priority
it
you
could
really
change
some
things
so
sketching
out
some
things
that,
like
I,
think
we
recognize
are
important
and
but
talking
about
reproducibility
of
results
and
how
to
get
that
code
and
also
talking
about
some
of
the
challenges
with
that.
B
D
B
Then
attention
real
or
a
workshop
or
something
along
those
lines
about
open
source
software,
maybe
a
couple
packages,
so
it
might
do
like,
for
example,
we
could
do
something
else,
a
pagan
but
have
Leo
do
something
I've
by
the
endo
and
me
on
on
on
spy.
So
I'll
keep
you
guys
in
the
loop,
because
if
we
also
may
be
appreciating
your
input
as
we
go
forward
and
then,
if
you're
at
a
to
you,
this
could
be
a
great
thing
to
get
involved
in.
So
right.
That's.
A
A
B
A
E
A
A
Let's
say
if
you
develop
through
the
code
yeah,
do
you
want
to
make
it
open?
He
said
really
like
no,
but
I.
Gotta
kinda
got
a
point
now
cuz
like
yeah
or
even
even
then.
Why
do
you
see
it
that
it's
like
that's
our
fault
like
a
funding
source
and
I,
cannot
really
criticize
that,
but
that
yeah
it
wasn't
sure
what
like.
What's
my
response,
what
do
I
say
but
yeah.
A
B
A
A
B
So
there's
a
couple
of
things
on
the
go:
I
know
Devon
I
requested.
If
you
don't
mind,
could
you
put
some
release
notes
together?
I
think
you
like,
but
we
need
to
put
those
out
with
the
merge
that
you
did
to
master
just
so
that
it's
very
clear
what
changed?
What
Steven?
All
of
that
so
in
the
slack
message,
I
included
a
link
to
one
of
the
release
notes.
That
was
just
really
well
done,
so
you
can
use
that
as
a
bit
of
a
a
guide
and
then
we'll
get
that
out
today.
B
B
Because
you
made
some
changes
that
I,
like
I,
also
made
some
upstream
changes
on
a
different
branch,
and
so
it'll
be
a
bit
of
merge
stuff
to
result.
That's
in
this
one!
Ok!
So
in
this
one
I
filled
out
the
fields
object
for
the
time
to
me
and
cleaned
up
a
few
things.
I
also
made
it
so
that,
like
II
and
J,
are
always
in
the
same
place
and
being
a
tree,
always
in
the
same
place
when
you're
talking
for
relations.
Ok,
because.
B
A
A
B
A
A
F
A
B
F
B
A
B
Look
for
the
commented
out
stuff
if
it
is
worth
keeping
like
totally
keep
it
don't
worry
about.
It
was
just
more
so
a
comment
that,
like
Duty,
want
this
or
not
was
with
some
of
those
comments,
but
then
yeah
here
I
was
just
wondering
we
can
leave
it
for
now,
like
that's
really
fine,
it
was
just
like
yes.
A
B
A
B
B
Is
if
it's
little
I,
so
if
you're
using
row
little
Y,
then
that
should
be
Sigma.
So
these
guys
here
right,
MCC
row
I.
If
it's
little
I,
it
should
be
Sigma.
If
it's
big
I,
what
we're
doing
is
actually
inverting
the
matrix
right.
It's
isotropic!
There
is
no
difference
between
them,
but
if
it's
an
isotropic
they
are
different.
I
think.
B
B
B
B
B
B
B
A
A
F
B
A
That's
right,
but
this
is
cell
centers.
F
B
So
the
other
thing
that
I
would
appreciate,
input
and
support
on
is
we're
starting
to
pull
some
of
the
like
useful
general
utilities
out
of
disk
retires,
potentiates
MPEG
and
put
them
in
somewhere,
there's
a
little
more
public
and
easier
for
other
people
to
jump
in
on.
So
I
started
by
pulling
out
some
stuff
into
matrix
utils.
So
now
this
is
in
open,
geophysics,
so
stuff,
that's
in
open
to
your
physics,
we're
hoping
is
like
useful
beyond
simply-
and
so
ideally,
this
should
be
like
among
our
highest
quality
code.
B
So
right
now,
I'm
a
tricky
details
like
needs.
Some
love
in
that
sense
to
get
peppy
to
get
the
documentation
in
order
and
all
of
that
sort
of
stuff.
There
are
fairly
simple
utilities.
So
this
is
things
like
make
it
back.
Nd
grid
cron,
three,
the
zero
and
the
identity,
and
so
if
people
are
willing
to
just
like
come
in
and
hit
on
some
of
these
things,
that
would
be
fantastic.
B
So
if
you
have
I,
don't
know
if
you
have
an
hour
at
the
end
of
the
day
where
you're
tired,
you
want
to
just
like
clean
up
some
things
and
contribute
to
something
going
in
and
adding
docstrings
then
also
changing
names
so
like
this
should
be
a
pet
bait
name,
it's
not
so
the
way
to
do
that,
where
it's
backwards
compatible
is
we
would
rename
this
allow
you
to
still
import
that
so
keep
one
below.
So
you
do
deaf
as
array,
capital,
n,
X
capital
dim.
B
B
D
B
D
B
B
F
B
D
B
B
F
B
B
No
just
an
octree
he's
been
rewriting
the
discretized
octree
implementation
in
c,
so
it's
much
better
and
much
faster,
and
so
he
then
like
there's
a
few
things
that
he's
thinking
through
a
little
differently
and
so
at
first
we
were
testing.
There
was
some
stuff
this
match,
which
is
fine
because
it
shouldn't
have
we
both
liked
the
way
they
rolled
it
up,
threw
in
the
read
that
Joey
thought
through
it
was
just
slightly
different,
so
they're
like
numbering
and
hanging
was
different,
but
now
we
sort
of
cut
it
through.
B
That
way
understands
like
how
he's
thinking
about
it
and
then
wanted
to
be
able
to
make
sure
that
we
can
read
in
now
a
UBC
mesh,
so
he's
able
to
get
that
up
and
running
thanks
to
Mike
for
providing
that
so
yeah.
So
now
it's
just
a
question
of
like
getting
the
operators
building,
and
so
we
might
try
and
connect
with
him
later
this
week
to
put
six
cities
yeah.
How.
