Description
No description was provided for this meeting.
If this is YOUR meeting, an easy way to fix this is to add a description to your video, wherever mtngs.io found it (probably YouTube).
B
B
Bbc
TV
model
files,
so
we
I
just
switched
the
implementation
around
that
should
work
a
little
bit
more
robustly.
I
wasn't
really
quite
sure
why
it
was
breaking,
but
I
just
did
something
that
was
a
larger
bust.
I've
been
working
on
the
line,
current
source
pull
request.
That's
a
probably
better
year
old
at
this
point,
I'm
just
trying
to
get
it
back
in
a
simulation,
because
it's
got
some
nice
stuff
in
there
as
we
got
with
regards
to
that
tree
stuff,
because
we
have
it
can
implement
the
line.
Turn
on
an
octree
mesh
I.
B
C
B
C
B
B
A
B
A
C
A
E
F
F
F
Now,
with
the
other
inversion,
where
we
have
just
a
single
EE
location,
and
then
we
have
a
roving
B
field
or
a
B
sensor,
yeah
now,
once
that
one's
it's
about
24
hours
and
I
still
haven't
got
any
duration,
so
I,
don't
know,
I,
think
it's
just
having
trouble
so
yeah
just
find
what
that
one
and
then
I
was
doing
some
benchmarking
and
I.
Don't
know
what
got
some
weird
things:
I'm
going
to
investigate:
I
ran
in
an
invert,
a
DC
inversion
on
a
like
a
brand
new
z4.
F
So
it's
like
say:
16
cores
or
8
cores,
16
virtual
area,
another
8
virtual,
a
a
little
bit
of
RAM
and
then
I
threw
it
on
our
big
machine
that
has
128
cores
and
the
actual
disease
Thoreau
performed
it
yeah
I,
don't
know!
What's
going
on
I
like
look
at
then
they're,
both
spending
about
the
same
time,
I'm,
outta
time
and
party,
so
which
is
kind
of
strange,
because
you
think
that
it
would
be
solving
the
equation.
F
F
B
F
I
just
have
to
make
sure
that
that's
see
if
I'm
doing
him
Altair
at
one
time,
cuz
yeah,
I,
swear
II
twisted
it
like
a
year
or
so
ago,
and
it
was
yeah.
I
could
see
the
difference
it
scaled,
but
not
now.
Yeah
I'll
just
take
a
look
into
it.
E
F
B
I
mean
like
I
would
have
liked
to
have
done
them
into
the
perdy.
So,
like
the
sixth,
a
new
version
of
it
I'm,
not
sure
what
the
license
is
like
and
it's
not
there.
It's
not
really
open
source
license,
but
they
do
head
of
light.
They
might
be
interested
in
something
if
you're
like.
Oh,
we
would
like
to
write
some
Python
wrappers
specifically
for
party,
so
their
site
on
wrappers,
cuz
I
know
they
published
some.
B
A
We
still
distribute
the
wrappers
which
actually
drive
right.
Isn't
it
the
wrappers
can
be
open
source,
but
then
you
have
to
go
to
them
to
get
the
closer's.
Okay,
that's
a
really
good
idea.
Do
you
would
folks
be
interested
if
we
just
started
Google
Doc
and
like
write
a
short
letter
and
we'll
see
what
happens.
A
G
Sure,
just
one
moment
here,
yeah
so
I
guess
maybe
an
update
on
that
eeehm
1d
stuff,
so
I've
gotten
it
to
a
place
where
we
can
kind
of
it's
pretty
much
in
sort
of
our
simple
organization
and
I've
got
the
main
set
of
tutorials.
So
we
could
do
forward
modelling
and
inversion
of
frequency
domain
and
time
domain
yam
locally
and
then
I've
got
the
stitched.
G
Working
and
I
also
was
able
to
make
a
I
think
I
made
sort
of
a
certainly
can
use
the
same
survey
class.
So,
instead
of
being
these
two
separate
but
completely
separate
things,
you
can
now
kind
of
design
a
survey
and
then,
if
it
has
more
locations
and
the
simulation
is
a
stiched
1d
simulation,
it
will
do
that
and
if
the
simulation
is
1d,
it
will
just
do
that.
G
But
yeah
now
I'm
kind
of
at
the
point
where
I
think
I
probably
need
some
input
from
some
other
people,
and
one
of
the
reasons
is
we
can
only
solve
the
vertical
magnetic
dipole.
So
long
as
the
radial
distance
is
large
enough.
If
the
radial
distance
goes
to
zero,
it's
no
longer
a
Hinkel
transform.
It
actually
can
be
written
as
a
Laplace
transform
and
so
the
the
current
filter,
or
way
that
we
numerically
evaluate
that
integral
doesn't
work
anymore
and
then
for
the
horizontal
loop
source.
G
There's
only
one
Bessel
function
in
that
integral
if
the
radial
distance
is
zero.
But
if
you
are
your
radial
distances
is
nonzero,
then
you
bit,
you
have
two
Bessel
functions
in
the
integral,
so
it's
you
have
to
solve
it
differently.
So
for
what
we
have,
we
can
compute
the
x
y&z
components,
but
when
the
receiver
is
in
some
different
locations
we
don't
have
those
solutions.
Yet
so
I
would
definitely
like
some
input
on
that
type.
I
played
around
with
it
a
little
bit.
G
G
Okay,
so
what
you
should
be
looking
at
right
now
is
warden
Holman,
and
this
is
this
is
going
to
be
the
the
radial
component.
This
is
the
vertical
magnetic
dipole
solution,
and
this
is
the
radial
component
that
you
would
get,
and
this
is
the
vertical
component
of
of
the
field
that
you
would
get
so
as
row.
The
radial
distance
goes
to
0,
J
1
will
go
to
0
so
that
that
Bessel
function
will
go
to
0.
G
G
It's
basically
been
designed
for
to
to
compute
dis,
Hankel
transform,
but
if
this
goes
to
1,
it
returns
a
bunch
of
Nan's.
So
it's
it's
not
able
to
go
and
compute
this
integral.
If
there's
no,
basically
oscillation
and
it's
no
decay
in
in
in
the
best,
because
it
will
always
be
equal
to
one-
is
that
sort
of
correct
leader.
C
I'm
that
the
equations
I
use
are
different
ones,
that
I
think
most
codes
like
dipole
1d
from
carry
key
or
I
what
he
uses
a
point
source
in
the
in
the
wife
number
frequency
domain,
and
then
any
source
signature
would
come
in
in
the
frequency
domain.
So
after
the
Heinkel
transform.
That's
why
you
can
use
the
same
hunk
of
transform
for
any
kind
of
survey.
You
always
have
the
same
kernel,
so
I
don't
have
that
issue.
C
G
G
In
a
practical
sense,
it
didn't
really
matter
too
much,
because
if
we
were
doing
frequency
domain,
then
we
would
be
using
systems
where
there
was
a
horizontal
separation
between
the
transmitter
and
the
receiver.
And
then
we
just
had
dipole
source
and
then
point
receiver,
and
whenever
we
did
I
guess
time
domain
systems,
it
would
usually
be
a
coincident
loop
system
which
we
could
solve
and
we
would
just
use
the
horizontal
loop
solution.
So
there
was
a
usable
solution
in
practice
for
the
frequency
and
the
time
domain
systems
that
were
common
for
airborne.
G
G
D
G
D
G
A
G
G
Don't
know
the
fine
details
is
it's
sort
of
a
good
time,
so
maybe
I'll
draft
something
up,
but
it's
somewhere,
people
can
read
through
or
maybe
I'll
just
make
it
in
the
as
issues
or
something
in
the
repository,
so
I'll
just
kind
of
document.
All
the
things
we'd
like
to
get
done
before
moving
it
into
simple
yep.
C
H
Nothing
on
the
nothing
on
the
course
and
big
library.
I'm
I
ran
more
inversion,
so
I
guess
trying
to
run
inversion
spectrum
data
which
has
been
challenging
but
trying
to
get
it
to
get
done.
Details
with
that,
and
then
we
had
a
meeting
last
week,
I
guess
with
with
John
and
D
as
people
try
to
think
start
thinking
about
having
more
general
input
files
or
foreign
versions.
I
think
that's
something
that
we'll
have
to
work
on
over
the
next
month
and
my
influence.
It
might
might
have
an
impact
on
other
people
here
in
the
channel.
A
Yeah
I
would
be
very
keen
to
sort
of
at
least
even
just
keep
up
pulse
on
those
conversations
about
input
files,
because
I
think,
as
we
think
about
sort
of
like
high-level
rappers
and
things
like
that
for
simpie.
We
might
have
some
thoughts
to
offer
just
in
terms
of
making
things
pretty
interoperable
and
hopefully
easy
to
go
between
yeah.
I
Yep
well,
no
nothing's,
a
simple
easy,
but
yeah
I'm
I'm,
seeing
the
end
of
the
tunnel.
Yeah
like
this
is,
as
I
said
last
week
was
again
the
end
of
the
in
the
end
of
my
committee.
At
the
moment
the
case
study
paper
is
in
prediction,
so
I
feel
like
interpretation
as
some
with
police
and
JCB
has
some
with
Christopher.
But
I
was
not
aware
of
for
production
and
in
term
of
figures
in
color.
I
So
it's
all
introduction
now
and
we
and
we
end
with
dingzi,
which
limited
the
revision
of
our
own
individual
paper
so
yeah,
so
so
yeah
now
I'm.
Now
it's
time
for
me,
like
I,
am
yeah
thinking
about
the
next
projects.
It's
like
make
me
play
a
with
I
in
pytho.
Again,
oh
good
work
on
another
case
study.
So
that's
that's
kind
of
what's
gonna
be
I'm
gonna
be
up
to
in
the
next
few
weeks.
I
Also,
it's
a
call
to
everyone
at
was
that
you
either
was
a
TBC
I'm
planning
on
updating
the
chief
website,
because
we
haven't
updated
the
list
of
publications
since
2017
and
when
you
search
search
for
our
paper
in
Google's,
it's
often
the
first
website
we
found.
So
if
you
want
to
send
me
your
free
prints
and
an
Associated
bit
text
for
the
reference
for
them,
I
will
try
to
update
the
website
publication
page
into
in
the
next
week
or
so.
A
Thanks
Steve,
oh,
that
would
be
great.
That's
a
great
Avenue
for
sharing
sharing
on
this
work
on
mr.
spot.
Also,
I,
don't
know
if
it's
just
hard
to
do.
If
it
is
that's
fine,
but
to
put
github
with
those
publications,
as
we've
been
at
least
recently.
You
know
with
a
lot
of
things
publicly
done
for
the
code.
We
put
them
in
the
same
peg
research
organization
and
it
would
be
nice
to
have
a
link
there.
A
I
G
I
Like
so,
it
was
in
that
website
there
is
a
communication
page
and
when
you,
when
you
look
for
one
of
the
you
beef
paper
on
Google,
it's
often
the
first
result
and
also
it's
a
it's
a
it's
a
it's
an
easy
way
it
get.
The
paper
for
like
knows
that
Oh
table
like
access
to
a
certification,
or
so
you
have
the
free
prints
there.
So
I
think
it's
a
greater
menu
for
like
for
the
visibility.
So
that's
yeah.
That's
a
website.
G
D
I
A
Ok,
couple
updates
where
to
start
I
guess
one
is
on
the
swung
slack
channel.
There's
a
bit
of
discussion
happening
about
she's,
about
having
either
a
shared
channel
between
synthetic
and
swung,
or
should
we
just
merge
and
have
like
simple
channels
in
the
swung
organization,
and
so
I
just
wanted
to
raise
that
and
have
folks
think
about
it.
I,
don't
think
we
need
to
make
a
decision
right
away,
but
there's
some
potentially
some
benefits.
A
I
know
a
lot
of
us
are
both,
and
so
it
would
be
one
less
slack
channel
to
monitor
and
like
also
sort
of
having
direct
connections
with
folks
in
Gem
pie
with
other
other
projects
could
be,
could
be
nice
so
something
something
to
think
about
and
yeah
I
don't
know.
If
anyone
has
initial
reactions
to
that.
H
A
We
could
still
have
I
think
multiple
channels
is
basically
have
like
transferor.
Almost
everything
over.
We
can
take
a
look
and
see
which
ones
were
actually
still
active
with
some
or
not,
but
to
get
like
simple
general
simpe,
discretized
simpang,
whatever,
so
that
it's
it
still
sort
of
like
the
same
general
structure,
but
now
actually,
with
with
a
much
larger
community,
might.
E
C
A
D
A
In
a
bit
or
dawn,
myth
mira
would
be
willing
to
put
in
I
mean
I,
don't
think
it's.
We
need
to
be
funding
a
huge
amount,
but
if
each
group
could
put
in
a
hundred
bucks
a
year
or
something
like
that,
that
makes
a
big
difference
because
I
think
it
costs
them
like
thousands.
And
so,
if
we're
gonna,
do
this
I
think
like
no.
B
A
Yeah,
that's
that's
good
to
know,
and
so
actually
I
can.
If
we
are
gonna,
do
this
I'll
just
ping
that
and
actually
ask
if
he
could
give
us.
Basically
what
would
a
reasonable
if
we're
bringing
200
people
in
how
much
should
we
be
be
paying
you
and
then
we
can
try
and
sort
of
distribute
that
amongst
amongst
ourselves
or
months,
like
the
organizations
that
were
in.
A
Okay,
the
next
thing
that
I
wanted
to
mention
is
with
the
paper
that
we're
working
on
didi
I've
been
running
some
simple
examples,
trying
to
compare
sort
of
the
benchmarking
with
other
codes,
and
this
again
comes
back
the
solvers.
It's
annoying
that
you
know
basically
like
the
bottleneck
in
compute
time,
is
completely
just
down
to
what
solver
we're
using.
A
So
in
some
senses,
it's
like
it's
not
really
a
code
comparison,
it's
like
a
solver
comparison,
but
that's
okay
and
so
I've
been
working
on
playing
around
quite
a
bit
with
the
octree
codes
and
really
trying
to
tune
the
the
first
just
layered
model
example,
and
so
if
anyone
here
is
actually
willing
to
just
take
a
take
a
pass
at
it
and
see,
if
there's
any
other
little
things,
you
could
see
improving,
ideally
accuracy,
but
also
you
know,
looking
at
potentially
reducing
compute
time.
I
would
appreciate
another
set
of
eyes
on
that.
A
Most
of
the
codes
are
sort
of
in
the
one
to
ten
percent
error
is
what
folks
have
been
hitting
and
right
now,
my
sort
of
best
hand
tuning
I'm
about
the
ten
ten
percent
error
on
average,
and
we
should
be
able
to
drive
that
down.
But
again
it's
probably
some
bottlenecks,
basically
with
with
parity,
so
so
yeah.
Would
anyone
here
be
willing
to
take
a
pass
and
just
fiddle
around
with
this
you're
interested
in
months?
Well,.
A
A
So
it
becomes
a
full
3d
example
and
so
I
use
basically
a
very
similar
mesh
design
with
the
octree
they'll
be
slightly
different,
because
I
don't
need
to
introduce
extra
refinement
around
the
blocks
later
and
then
second
example
is
based
on
the
Marlin
model
and
so
that
one
I'm
just
getting
started
on
the
base
sort
of
tensor
mesh
has
like
ninety
million
cells,
I,
think
sorry,
theater,
yeah
and
so
trying
to
the
first
problem
is
really
can
I
design
an
octree
mesh
that
is
feasible
for
for
solving
this
problem,
ideally
with
a
direct
solver
like
Paradiso,
but
we
might
need
to
switch
over
to
a
turret
'iv
to
handle
that
so
I'm,
just
just
getting
off
the
ground.
C
A
B
C
Custom
always
hard
to
fill
just
introduced
it
shortly
before
we
started
if
that
I'm
using
total
field
and
I
think
sim
pegas
well
right,
I.
C
I
see
your
concern
that
it's
one
way
to
solve
a
comparison,
so
it's
Phoenix
pet
SC
in
my
case,
I'm
I'm,
the
solver
as
well,
and
then
in
sympathy.
It's
party
but
I,
think
you
should
emphasis
in
your
texts,
because
we
also
should
lay
out
what
can
these
tools
do
otherwise
and
that's
where
you
have
to
put
in
all
the
stuff
from
sim
pack
that
they
can
do
other
methods.
Other
things,
the
user
interface,
which
simply
as
much
more
than
any
of
the
other
codes,
also
examples
online.
All
that
stuff
and
also
I,
mean
I.
C
Think
it's
really
exciting
that
there
are
different
meshes
because
the
other
two
codes
they
have,
they
have
a
tetrahedral
meshes.
Then
I
would
have
just
a
regular
ten
summation.
You
would
have
oak
tree
meshes
so
I
think
that's
really
an
exciting
point
to
see
these
differences
or
seem
clarity's
yeah.
A
C
Go
question:
custom
has
a
lot
of
setup,
so
they
have
total
field,
they
have
primary
secondary
field
and
some
potential
approaches,
I
think
customers
a
lot
of
different
approaches
and
he's
working
at
the
moment.
Also
on
on
time
domain,
there
he's
now
making
a
paper
for
as
you
earlier
and
other
methods.
Actually
he
I
think
he
permitted
four
or
five
different
time.
Stepping
methods
I
think
he
has
a
lot
of
things
but
I,
don't
know
the
details.
C
You
bb,
if
you
want
I,
can
send
you
the
link
to
the
main
custom
paper
if
you
interested,
because
he
made
a
comparison
of
a
lot
of
different
approaches
to
solve
it,
which
is
sort
of
interesting
picture,
I
think
is
just
using
pet
SC
as
a
solver,
but
I
don't
know
yeah,
but
it's
just
basically
the
other
two
codes
and
also
it's
mainly
C
SEM,
in
contrast
to
sim
pack.
So
it's
it's
mainly
CSU.
C
E
E
C
A
I
know
I'm
encouraged
that
it's
the
setup
is
working
pretty
pretty
well
and
I
mean
these
simulations
aren't
taking
too
long
to
run
so
so
that's
so
yeah.
We
still
have
space
to
play
and
improve
cool
mind
if
I
share
the
repo
cause,
I,
think
it's
so
private.
Yes,.
C
A
Oh,
we
had
to
other
thoughts
with
bats.
One
was
just
like,
and
this
is
maybe
a
question
for
later
is
where
we
actually
put
that
recode
later
on
is
it
could
be
a
cool
opportunity
to
maybe
think
about
either
using
that
open,
geophysics,
org
or
if
we
want
to
do
something
with
swung?
Where
there's
like
a
swung
research,
org
I,
don't
know
it's
just
one
question
to
kind
of
put
on
the
radar.
Yes,
oh
yeah,
and
then
the
last
thing
is
that
this
actually
really
nicely
aligns
I.
A
Think
with
the
motivation
of
the
Jupiter
meets
the
earth
project,
which
is
like
basically
trying
to
advance
sort
of
Jupiter
technologies
being
driven
by
scientific
use
cases.
So
one
of
the
things
that
I
raised
with
Fernando
today
and
will
hopefully
bring
up
with
the
next
meeting
I
have
with
folks
from
ncar.
Is
that
they're
actually
looking
at
creating
like
a
binder
for
HPC?
A
So
if
you
had
so
like,
we
could
potentially
actually
put
these
examples
on
Shayan
the
big
supercomputer
run
by
end
car
and
be
able
to
send
out
links
to
people
which
I
think,
and
so
I
will
keep
sort
of
asking
about
that.
But
I
just
wanted
to
share
that.
I
thought
that
it
was
like
potentially
something
kind
of
exciting
that
we
could
do
to
elevate
elevate
this
and
have
other
people
be
able
to
go
in
and.
A
I,
don't
know,
does
anybody
else
have
any
other
other
items
you'd
like
to
chat
about
or
bring
up.
H
A
One
of
the
things
we
brought
up
and
I
don't
know
if
this
would
apply
with
ICT.
Really
not,
but
that's
fine
is
you
actually
just
want
to
do
our
own
thing
and
like
ask
Matt
and
others
that
swung,
if
we
could
just
do
something
like
transform
like
more
like
that
style
of
workshop
just
on
our
own,
but
potentially
in
that
same
time,
slot.
H
Yeah,
you
can
ask
s
e-g,
but
I
have
the
feeling
that
that's
their
cow,
whether
they
try
to
milk
every
year
and
I,
don't
think
they'll
fly
like
we
tried
many
times
to
email
them
and
ask
them
full
online
and
they're
still
digging
their
heels
with
this
hybrid
approach.
So
unless,
unless
anyone
like
raises
their
hand,
anyone
say
I,
wanna
I
want
to
commit
to
go
to
Houston
there
and
like
how's.
This
thing
I
would
just
email
them
and
tell
them
that
we're
out
Bitcoin
is
out
for
sure
he's
not
gonna.
H
A
H
H
Think
we
should
I,
don't
have
the
bandwidth
to
do
it
myself
and
I
would
say.
If
we
do
this,
we
should
be.
We
should
be
targeting
exactly
the
methods
that
we
want
to
cover
and
just
you
know
going
deep
into
it
because
I'm
not
sure
people
are
getting
much
out
of
it.
If
it's
just
like
general
general
synthetic,
you
know
it
needs
to
be
applied
and
like
today
we're
gonna
meet
and
we're
gonna
do
maggin
versions
tomorrow
me
then
we'll
do
you
know
iam
Wendy,
that
kind
of
stuff
I
think
works.
H
E
Power
powerline
effect
and
still
kisi
got
a
lot
of
revision.
Remember
the
Ben
Blas.
When
we
went
to
Denver
he
he
gave
a
talk
in
this
this
class
right.
He
was
actually
reviewer
and
he
made
tons
of
like
zillions
of
questions.
I
just
finished
to
answer,
but
actually
I
made
his
word
kind
of
sort
of
more
reliable.
B
B
E
B
G
E
G
Is
it
about
it's
about
the
em1
D
stuff,
so
I
thought
you
might
actually
be
interested
in
it,
mostly
that
for
the
frequency
domain,
eeehm
systems
that
we
usually
use,
we
can
use
a
vertical
magnetic
dipole.
We
have
a
way
of
computing
the
integral,
but
only
if
the
radial
distance
like
the
radial
offset
is
large
enough.
So
if
you
had
something
you're
trying
to
do
where
the
the
transmitter
and
receiver
were
vertically
separated,
we
can't
right
now
we
can't
compute
that
response.
E
E
G
So
that
solves
one
of
the
problems,
the
other.
The
other
thing
we
would
like
to
solve
is
the
horizontal
loop.
We
can
solve
that
for
a
zero
set.
We
can
do
a
coincident
loop
system,
but
if
you
you
have
the
solution
for
a
circular
horizontal
loop
and
you
have
a
non
zero
horizontal
offset.
You
have
two
Bessel
functions
in
that
integral
and
that's
much
harder
problem
to
solve.
I
did
it
once
with
a
like
an
adaptive,
quadrature
method,
the
MATLAB
uses,
but
that
takes
quite
a
while,
and
it's
not
always
the
most
solution.
E
So
we
can
get
some
help
from
theater,
so
here's
our
best
expertise
about
that
was
dumped
your
vessel
into
roll
or
something
like
that.
So
yeah,
it's
it's
on
my
bucket
list,
cuz
yeah
it'll
be
nice
to
handle
like
an
iam
on
the
FM,
where
you
define
the
wire
path.
Man
you
can
put
wherever
your
receiver
is.
So
it's
on
my
list,
but
yeah
I,
just
didn't
have
a
time
to
work
on
it.
Yeah.
G
So
so
I
guess
the
you
missed
the
first
part
of
the
meeting,
but
I
I've,
basically
taken
the
em1
d
repository
and
I've
adapted
it
so
that
it
has
a
like
a
more
simple
like
framework
and
I
have
tutorials
like
the
main
set
of
tutorials
for
everything,
local
and
stitched,
Fe,
M
and
TEM
inversion
playing
around
with
some
different
waveforms.
So
there's
now
there
is
now
a
template
to
really
go
in
and
test
and
see
if
it
can
do
all
the
stuff
that
we
want
it
to
do
so.
G
E
G
G
Well,
I'll
see
if
using
correct,
coordinate
systems.
Well,
maybe
yeah
take
that
oh
yeah
I
for
some
reason,
I
thought
that
it
wouldn't
I
was
surprised
that
the
solution
wouldn't
be
stable,
because
I
had
an
exponentially
decaying
function
already,
because
there
was
a
vertical
separation.
So
I
was
surprised
that
it
was
giving
me
out
a
bunch
of
Nan's,
but
that
would
that
would
make
sense,
I
guess
what
I
had
before
it
was
the
best
function
that
was
decaying
fast
enough.
F
G
It
should
be,
it
should
be
a
plus
I,
Omega,
T,
Fourier
Convention,
and
it
should
be
X's.
East
y
is
north
and
Zetas
positive
upwards,
and
you
can
figure
out
which
is
which,
by
looking
at
what
you
looking
at
the
the
Z,
the
Z
X.
While
you
can
look
at
what
quadrant
it
is
on
the
complex
plane,
it
should
tell
you,
okay,.
F
G
F
G
It's
confusing
a
bit
but
yeah
it's.
It
should
be
X,
easting,
Y,
northing
and
Zed
positive
up
because
I
we
brought
it
up
in
a
conversation.
Maybe
two
months
ago,
yeah,
we
all
came
to
consensus
and
just
said:
simpang
is
going
to
be
this
way
like
period
so
yeah.
That
was
that
was
designed
that
way.
Okay.
G
G
A
One
of
the
quick
thing
just
to
know
for
everyone
I
think
a
GU
abstract
doesn't
is
coming
out
sort
of
soon,
and
so,
if
you
will
want
to,
if
you
think,
I
put
anything
there
and
want
support
from
anyone
in
this
impact,
team
it'd
be
fun
to
have
a
few
abstracts
in
there,
where
I'm
running
a
session
again
on
open
source
software
like
the
lightning
talked
or
that
we've
done
in
the
past
years.
A
So
to
if
you
have
anybody
in
mind
who
is
perhaps
newer
to
the
open
source
software
worlds
that
would
be
great
to
highlight.
It
would
be
great
to
get
suggestions.
We
get
to
invited
speakers
and
we
try
and
make
sure
it's
not
just
like
this.
You
know
the
same
faces
all
the
time
or
sort
of
the
big
projects
that
everyone
already
knows
about.
It's
nice
to
use
it
as
an
opportunity
to
highlight
other
folks.
So
if
you've
come
across
a
project
where
you're
like
this
is
cool,
I
want
to
hear
more
about
it.
