A
Hi
good
morning,
everyone
today
is
March
14,
it's
pi
day,
happy
pi
day.
We
have
a
good
team
here
today.
Let
me
just
start
off
with
some
project
management
stuff.
We
most
of
my
time
last
week
was
dedicated
to
doing
participating
in
a
couple
different
meetings
with
with
men
and
Carol.
While
they
were
here
on
a
visit
and
then
getting
ready
for
teaching
at
a
his
carpentry
reproducible.
A
Science
workshop
sat
on
that
this
week,
so
I'll
be
teaching
the
exploratory
data
analysis
in
jupiter
notebooks
this
week,
so
I'll
be
back
back
in
the
bay
area
next
week,
and
that's
about
all
I
have
to
report
this
week
so
looks
like
the
next
person.
Let's
go
hit
the
auction
items
from
last
week.
We
had
a
please
weigh
in
on
the
great
red
line
debate
up
top.
B
Let
us
know,
let
us
know
in
the
issue
and
we
can
try
I
think
we
have
I
had
a
chance
to
have
a
good
discussion
with
me
last
week
and
I'll
post
later
on
the
issue,
but
but
if
anybody
has
extra
extra
perspectives
on
that,
please
please
picture
on
the
issue.
It's
one
that
gets
gets
a
little
contentious.
So
it's
good
to
hear
from
a
lot
of
voices.
A
Okay,
thanks
panno
and
the
other
action
item
from
last
week
is
right,
documentation
as
a
satellite
participants
of
the
doc
athan,
so
that
was
for
the
docs
on
that
occurred
at
bids
and
online
last
week.
Can
we
check
that
one
off
whoever
created
it
that
good
yep
matoba
great
and
then,
let's
see
it,
looks
like
we
had
action
items
from
februari
that
need
to
be
checked
off
with
the
declarative.
Widgets
projects
like
to
be
part
of
the
new
Jupiter
widgets
looks
like
Mateus
responded.
A
Yes,
keith
is
deferring
to
Gino,
so
let's
all
reach
out
to
Gina
outside
of
this
call
can
be
not
always
online,
and
then
we
can
cross
that
that
one
off,
not
some
kind
of
great
so
weekly
news
by
organization,
so
can
get
updates
via
these
posts.
Links
to
the
post
updates.
That
carol
has
provided
they're
super
useful.
You
can
see
how
many
commits
were
made
over
the
week,
yet
cetera
and
then,
of
course,
team
leads,
and
we
get
to
your
section.
C
C
Quick,
okay,
so
nothing
much
I
worked
on
documentation
and
so
documentation
on
ipython
should
be.
It
should
be
better
now,
I
search
merge
a
few
things
not
to
become
a
common
people.
Thank
you
for
Carol
tour
for
reviewing
my
my
usual
bad.
English
are
not
so
great
pissed.
So
if
ronaldo
already
said
you
would
look
at
the
vid
nine
issue,
so
that's
great.
It
would
be
one
one
thing
that
should
know
how
long
I'm
working
a
lot
on
allowing
a
synchronous
code
in
the
record.
C
D
C
And
it's
also
close
to
the
core
ipython,
so
I
would
really
appreciate
a
couple
of
extra
pairs
of
eyes
and
the
more
the
better,
because
it's
some
some
quite
tricky
code
that
might
have
side
effects,
but
it
works
great
in
service
test.
There
is
good
idea
on
how
to
use
this
recent
aggression
with
many
other
groups
if
you
have
a
favorite
favorite
event,
troops
which
is
not
integrity.
C
Please
give
me
feedback
from
the
API
so
that
I
can
know
whether
it's
the
right
one
or
not
already
into
thing
with
other
io
library,
helped
me
to
see
that
I
had
first
time
limitations.
So
now
I
think
it
should
be
great
and
it's
really
nice
to
use
if
you're,
watching
a
screen,
scope
same
thing
here
comes
from
internet
and
listening
to
that
later,
I,
please,
in
this.
B
Is
great
I
don't
know?
Do
we
have
anyone
on
the
E
was
using
it,
the
I
think
I
think
I
owe
or
the
other,
the
other
a
think,
libraries
in
Python
sensibly,
because
honestly
I'm
not
and
so
I'm,
not
the
best
person.
That's
qualified
person
to
comment
on
the
AC
is
because
I'm
not
not
using
those
libraries
myself
early
for
anything.
So
if
anyone
of
the
team
is
has
kind
of
gotten
into
the
the
async
async
a
waist
band
wagon
in
Python
3,
it
would
be
great
to
have
your
feedback
so.
C
It's
a
bit
of
a
cache
catch-22,
because
I
found
that
I
was
not
using
the
library
because
they
were
almost
impossible
to
use
as
a
record
and
now
that
it
works
as
a
record
because
of
dispatch.
It's
much
much
more
friendly
to
use
and
I
completely
understand
that
only
a
few
people
would
use
the
library
we
have
integration
with
it,
because
one
of
these
library
is
literally
a
week
old,
so
yeah,
oh
yeah.
C
I
would
I
would
appreciate
some
eyes
at
least
on
the
core
things
not
to
make
sure
I
don't
break
any
semantic
of
ipython.
Most
of
the
behavior
is
is
knocked
out
by
default,
but
should
not
change
anything
unless
you're
writing
things
that
are
already
stacked.
Actors
became
known
that
errors,
so
it
shouldn't
affect
a
lot
of
people.
C
B
B
E
C
Okay,
so
I
said
it
works
on
that
book
on
all
four
times
that
basically
work
till
I
fight
and
it
should
be
automatic.
You
shouldn't
have
to
do
anything.
So
that's
going
one
other
thing
that
I
would
like
to
have
feedback
on,
especially
from
people
who
use
QT
is.
Apparently
there
is
a
contention
between.
Should
we
set
the
version
of
all
Kiki
API
at
once
to
version
2
or
only
to
the
one
we
use.
C
It
seems
like
setting
everything
to
be
too
with
solve
problems
for
a
number
of
users
and
not
setting
it
in
the
case
of
maybe
someone
we
use,
two
different
version
of
different
API
at
the
same
time
seemed
to
be
more
theoretical
thing
that
someone
might
be
doing
so.
We
are
not
setting
it
because
it
might
break
some
people
go,
but
we
will
not
have
ensure
people
use
this
kind
of
weird
happy
I.
If
I.
C
So
I
would
be
in
favor
of
reopening
pull
request,
but
what
clothes
or
redoing
it
and
take
a
stand
like
okay,
we
are
using
API
v2,
we
are
not
compatible
with.
It
shines.
A
TI
ep1
and
fix
an
actual
problem.
User
has,
instead
of
partying
on
the
potential
problem.
With
my
sinful
use
and
I
would
like
other
people
to
pitch
in
and
say
yes
go
for
it,
it's
okay,
it
breaks.
You
can
river.
That
cater
is.
G
B
F
F
C
D
C
C
So
I
can
move,
I
can
move
this
one
and
yes
and
otherwise
I'm
going
to
trust
them
issue,
because
there
is
not
much
more
I
can
do
couple
of
my
remaining
issue
or
rat's
nest
for
right
item
six
and
probably
try
to
do
all
these
are
by
end
of
week.
I
don't
get
a
lot
of
back
request
and
if
all
my
target
Ricky
I
miss
it
I,
don't
think
otherwise.
C
B
B
Just
one
of
you
guys
want
to
pitch
in
about
the
notebook
kind
of
updates
on
the
notebook
and,
if
you
do
have
custom
updates,
maybe
drop
drop.
A
couple
notes
for
my
PSS
summary
later
yeah.
H
It's
alright
to
notes
right
now.
The
short
is
that
we're
on
5.0,
beta,
2
and
I
think
we're
ready
to
release
a
Matthias
and
I
are
just
going
to
merge
in
one
more
PR
11
little
bug
fix
I've
been
testing
myself
I'm,
not
sure
how
many
other
people
have
been
testing
it,
but
it
seems
clean
totally
fine
to
me
so
I
guess
I'd
like
to
get
some
some
feedback
about
about
whether
everybody
is
comfortable
to
go
ahead
and
release
five-point.
Oh
I
run.
B
From
master
regularly
so
that,
if
something
breaks
it
hits
me
immediately,
I
don't
know
if
I
think
other
people
are
in
the
same
habit.
That
I
am
a
kind
of
running
running
most
of
our
coach
from
a
story,
even
though
it
obviously
does
create
some
occasional
pain.
But
it's
a
good
way
of
being
the
Canaries
in
the
coal
mine
and
I,
encourage
people
within
reason
and
whenever
they
can
to
do
to
operate
in
that
way,
just
keep
up.
Keep
a
Conda
environment.
B
I
had
a
condign
that
I
call
stable
where
I
don't
I,
don't
let
it
see
anything
from
gift,
so
that
is
strictly
released.
Official
release
packages
but
but
I,
my
regular
working
environment
is
pure
master
of
everything.
One
gets
so
it's
a
good
way
to
see
the
mess
early
and
that
would
be
would
be
good
at
most
of
us
have
that
as
a
practice
as
long
as
its
reasonable
people
call.
H
B
Yeppa
get
each
one,
yes,
no!
You
want
to
use.
Mr,
if
you
are
on
the
map,
you
can
homebrew
insult.
Mr,
the
games
of
command
will
be
called,
mr,
which
is
short
for
multi
repository,
and
you
basically
tell
it
what
we
pose
you
want
and
they
can
be
anywhere
on
your
filesystem.
You
register
in
a
top-level
config
file,
your
mr
repos,
and
then
you
simply
type
mr
update,
and
it
will.
I
have
like
20
and
25
repos
and
I
type,
mr
updates,
and
it
will
pull
from
all
of
them.
That's
great
tweet,
yeah.
H
B
B
Great
so
like.
I
In
the
office
opposite
tack,
where
I'm
running
on
the
latest
stable
version
to
make
sure
that
the
master
I
pie,
widgets
and
other
repo
that
I'm
working
on
work
with
it,
are
compatible
with
the
latest
stable
version
so
that
we
don't
get
any
surprises
when
we
actually
release
but
I'm
glad
people
are
taking
both
decks
yeah.
How?
How.
B
H
B
Would
that
would
give
the
RC
at
least
a
few
days?
I
don't
know
I
mean
yeah,
I
eyeball
gaming
on
the
week.
Probably
what
did
you
have
to
take?
It
definitely
advertisers
advertise
it
on
the
mailing
list
and
we
can
tweet
about
it
and
we
can
retweet
it
from
the
project
so
that
people
tested
I
mean
it's
good.
It's
your
point,
o
rly.
So
it's
a
good
idea
to
get
some
eyeballs
on
it.
B
I
B
I
G
B
G
A
So
what
folks
have
been
doing
is
creating
just
a
brief
issue
for
releases
on
and
pinky
and
then
I've
been
adding.
Those
two
are
too
early
calendar.
Okay,
yes,
one
is
like
a
catch
mechanism
until
we
can
make
this
process
more
automated,
but
at
least
we're
starting
to
keep
track
of
everything
that
we
have
in
the
pipeline.
A
E
J
Let's
look
my
life
so
aside
from
doing
some
testing
stuff
in
the
notebook
which
thanking
Paul
and
Matthias
and
then
not
as
leader
that
I
I've
been
working
on
getting
messing
around
with
a
lot
of
trade
with
stuff
and
just
general
configuration
passing
around
things.
So
one
bit
of
that
has
been
to
at
the
minimum,
have
a
post
based
method
so
that
we
can
in
the
download
as
button
inside
the
current
notebook
for
the
classic
network.
J
All
of
the
all
of
the
different
treatments
that
are
available
under
classes
that
are
subclasses
of
a
particular
app
that,
along
with
their
type
and
default
information,
I,
haven't
figured
out
exactly
how
to
convert
them
into
a
JSON
schema
yet
which
is
what's
needed
for
the
purposes
of
other
generating
at
you,
I,
but
yeah.
So
there's
progress
on
both
of
those
fronts.
B
J
B
G
Too
much
there's
a
there's,
been
some
PR
supper
dating
backer
sex
and
things
there's
a
new
one,
that's
kind
of
revving
all
the
versions,
but
not
a
lot
too
exciting
there.
I
was
planning
to
add
super
lab
to
the
Decker
sex.
What
I'm
going
to
do
it
right
after
merging
this
PR
that
updates
everything
and
then
Jupiter
lab
should
be
in
the
doctor,
snacks
for
the
end
of
the
week
prevalence,
which
should
make
it
easy
to
deploy
guerrilla
but
super
hub
and
stuff
which
version
Sailor,
Jupiter.
All.
K
B
Including
back
being
done,
for
example,
at
no
risk,
one
of
the
deployments
is
already
often
learning
that
way
and
what
the
team
there
is
doing
is
basically
telling
sort
of
their
most
advanced
users
know
about
it
and
so
that
they
can
use
it
in
tested,
but
otherwise
users
have
no
idea.
Stephen
presidency
goes
because
there's
no,
it's
not
a
little
just
one
landing
page
and
there's
no
there's
nothing
in
DUI.
That
would
point
them
in
that
direction.
But
it's
like
some
tests
with
a
few
and
friends
and
family
who
were
willing
to
do
that.
K
K
K
A
L
Well,
Darien
last
week
to
the
work
of
allowing
the
the
full
layout
to
refresh,
if
you
refresh
the
page,
so
that
the
key
step
toward
being
able
to
save
an
application
state
and
rehydrate.
So
you
have
all
the
same
widget,
so
you
had
open
all
the
same
files
on
the
same
warranty
so
that
work
is
done.
There's
one
more
bug
fix.
We
need
to
add
to
make
it
so
that
it
goes
missing.
Data
it'll,
so
it'll
still
do
the
right
thing.
Look,
look
correct
not
have
hold
on
the
page.
L
That's
on
the
phone,
we're
also
continuing
the
work
we
started
last
week
to
split
the
repository
into
multiple
packages
to
make
them
easier
to
consume,
for
both
third-party
use
and
for
writing.
Extension
has
turned
out
to
be
a
lot
trickier
than
we
thought
we
moved
on
through
some
iterations
of
putting
out
the
packages
in
ways
that
make
sense
to
be
separately
releasable
packages,
but
we're
just
about
there
hope
they
get
done
dango.
You
find
me
we're
finding
circular
dependencies.
L
L
I
L
Will
continue
to
be
one
Python
package
called
River
lab,
but
it'd
be
good
versions
of
these
severed,
so
the
independent
reversion
NPM
packages
any
associated
with
it.
Then
our
extension
was
based
on
web
pack.
1
point
0
the
2
point
0
landed
a
few
months
ago,
the
final
release
and
which
includes
support
for
Empress
script.
L
Six
so
went
to
the
work
of
updating
our
our
extension
builder
and
pull
a
web
pack
plug
in
the
be
compatible
of
two
point:
O
looking
toward
the
future
on
that
one
and
chris
is
working
on
single
document
mood
for
the
doc
panel.
So
you
can
switch
to.
It
was
what
some
might
know
as
a
Zen
mode
and
sublime
where
you're
just
you're
only
viewing
one
document
that
has
no
tabs
and
you
can
switch
between
documents
that
are
visible.
So,
instead
of
having
the
full
block
layout
or
visible
to
you,.
B
Think
so
much
because
that's
I
think
that's
something
that
has
been
brought
up
multiple
times
by
users
as
as
one
aspect
of
the
new
UI
which
for
for
advanced
users
or
the
large
screen,
is
very
nice,
but
who
kind
of
were
used
for
the
simplicity
of
I
click.
I
started
up
my
notebook
and
there's
nothing
else
to
think
about,
especially
with
beginners
and
an
educational
context.
It
was.
B
B
D
Don't
I,
don't
really
want
to
characterize
what
the
intent
was,
but
it
really
came
from
this.
This
dislike
of
an
ide
like
interface,
and
you
know
just
it's
too
busy
or
whatever
so
I
I.
Don't
necessarily
think
that
that's
a
realistic
complaint
because
you
open
up
one
document
at
a
time
it
only
gets
busy
if
you've
been
making
it
busy.
Nonetheless,
I
think
a
demo
version
that
looks
a
lot
closer
to
the
classic
notebook
and
then
transform
it
to
the
version.
D
B
It's
very
dazzling,
but
it
can
be
a
little
bit
overwhelming
and
you're
absolutely
correct
and
that
it
can
trigger
a
bit
of
a
negative
reaction.
I
don't
need
all
those
Delta
whistles
I
just
want
to
get
my
work
done.
Why
are
you
messing
with
it?
So
we
typically
emphasize
very
strongly
the
point
that
people
are
not
losing
anything
regarding
the
file
that
the
documents
on
disks
are
not
changing,
but
I
probably
don't
emphasize
enough
that
they
they
don't
have
to
lose
their
work
flow
patterns.
B
If
they
don't
want
to
thats,
but
all
of
these
things
are
things
that
are
new
because
in
some
cases
they're
needed,
but
that,
if
they're
perfectly
happy
with
the
way
things
are,
we
will
respect
that
and
I
think
it's
a
very,
very
wise
fun
to
keep
in
mind,
especially
as
we
start
going
public
kind
of
as
we
demo
it
and
show
it
more
and
more
either
formally
in
presentations
or
just
with
colleagues
and
people
kind
of
sits.
Next
to
the
other
computer.
G
B
G
B
Daddy's
messages
spot-on
and
with
this
new
mode,
when,
when
it
when
Chris
lands,
it
I
think
what
we
can
do
is
just
make
sure
that
we
we
enter
through
there
and
spend
a
little
bit
of
time
kind
of
clarifying
to
people
look.
This
is
going
to
give
you
the
same
experience
you
had
before
don't
worry
about.
It
were
really
only
genuinely
trying
to
make
things
better
for
everyone
not
to
rip
out
the
things
that
were
comfortable
and
valuable
to
you.
G

A
little
duper
lab,
belated
I've,
been
getting
help
from
people.
Who've
been
helpful,
which
is
nice
today,
I'm
working
on
seeing
what
building
something
like
Phoebe
on
super
lab
would
look
like,
because
smoking
Ruth
get
folks
have
socks
hooked
up
to
TV
that
don't
work
anymore,
because
Phoebe
doesn't
really
work
anyway
and
some
investigating.
G
Maybe
O'reilly
just
designed
people
to
other
things,
not
sure,
but
the
part
of
it
is
that
moving
forward
Phoebe
once
so,
Phoebe
has
had
the
copy
of
all
the
JavaScript
out
of
the
old
notebook,
because
it's
not
a
proper
JavaScript
package,
so
it
can't
express
dependencies
or
anything
on
it
and
so
I
think.
The
plan
to
move
series
board
was
to
wait
until
another,
wait
until
something
like
Jupiter
lab
or
interact,
or
something
we're
ready
was
ready
to
build
on
top
of
to
make
it
a
more
sustainable,
smaller
project
of
its
own.
L
L
I
I
I
M
The
thing
is,
the
goal
is
to
use
to
attach,
so
the
other
package
were
that
we
extracted
from
bt
brush
and
add
to
jason
from
jhe's
materialization
retention
there,
that
you
put
the
binary
messages.
Currently,
95
are
you
making
that
he
has
three
modes?
One
is
pure
Jason.
The
second
one
is
basic
before
and
the
last
one
is
the
first
one
that
requires
the
TR
and
that
I
would
just
said
in
two
thousand.
B
G

A
N

It
was
just
a
great
week
last
week,
a
lot
of
good
things,
return
special,
thank
you
to
Matthias
for
all
his
energy
on
the
dock
athan.
It
was
great
to
see
lots
of
projects
move
forward.
So
that's
awesome
and
UV.
Gabe
and
Ryan
gave
us
a
really
nice
demo
of
Cooper
Nettie's
being
used
as
data
eight
and
we're
going
to
try
and
push
forward
and
try
and
get
some
generic
stock
written
of
that
once
they
get
it
all.
Buttoned
up
we'll
be
able
to
move
it
over
to
chipper
her
yeah.
B
We
really
need
really
should
have
as
soon
as
you
me
and
Ryan
are
happy
with
it
that
the
dust
has
settled
on
that
we
should,
which
is
advertised
at
more
prominently.
I
suspect
a
lot
of
people
are
going
to
find
out.
It's
super
useful
in
many
many
places
it
was,
it
was
cleaning.
It
was
elegant.
It
was.
It
was
really
nice
to
see
that
in
action.
A
I'm
going
to
guess
background
noise,
alright,
so
next
year
we
have
conferences
and
outreach.
Let
me
just
go
through
the
list:
Carol's
added
code
land
is
a
new
conference
coming
up
in
April
April
21st
22nd
on
Carolyn
Sofia
will
be
serving
on
a
panel
for
open
source.
So
there's
the
link
there
and
then
we've
already
announced
today's
the
last
day
to
submit
proposals
to
Jupiter
con.
So
that's
probably
the
night
tonight
is
the
deadline.
A
A
B
Want
one
that
I
saw
go
by
on
the
open
drinkin
man
lives
in
paris
in
june,
so
I
at
least
children.
The
CSP
is
open
if
you
wanna,
if
you
want
to
maybe
submit
something
and
I,
don't
know
if
my
PS
might
be
around
Paris
other
time
or
other
others
in
our
European
group,
with
jun,
12
and
13
is
going
to
be
in
Paris.
I
put
the
link
there.
Okay,
Paris.
A
Nope
in
last
week
in
the
meeting
I
shared
the
our
github
projects,
event
schedule
and
I
just
I'm
sharing
my
screen
right
now
to
show
where
I'm,
adding
adding
these
events
summer
issues.
Others
are
just
notes
here
in
the
calendar,
but
we
can
always
everyone
can
go
here
and
see
what's
going
on
for
for
the
next
well
year
or
so,
and
I've
also
asked
team
members
to
add
themselves
to
the
issues
once
they're
creative.
A
M
A
F
A
B
No
just
to
remind
people,
please
what
we
have
a
few
more
hours
in
the

for
anyone
to
submit.
So
if
you
have
a
colleague
who's
on
the
colleague
who's
understand,
if
you
want
to
tweet
about
it,
if
you,
if
you
have
any
any
any
network
that
you
can
reach
once
more,
the
more
the
more
proposals
we
get,
the
better
and
I
do
I
know
that
I
have
so
few
people
have
shared
roster
proposals
with
me
that
I'm
giving
feedback
home
so
I'll
get
on
that
right
away.
I.
