A
Good
morning,
everyone
today
is
Tuesday
februari
2680
center
Jeff
Green
will
head
over
to
our
dropbox
paper
notes
and
start
going
through
work
for
this
week,
and
some
of
us
look
at
some
of
the
things
that
we
finished
last
week.
So
we
are
still
gathering
feedback
on
dropbox
paper
so
looks
like
there's
some
still
some
challenges
with
exporting
markdown
for
our
weekly
summary
that
Matthias
is
experiencing
and
you
still
seeing
some
lag
so
folks
using
it
this
week,
please,
if
you're
experiencing
some
of
the
same
issues.
A
Please
go
ahead
and
report
that
and
let's
see
weekly
news
by
oh
cool,
ok,
weekly
news
by
organization:
this
is
new
and
Carol.
Do
you
mind
if
I
just
circle
back
to
you
in
a
minute
sure
on
that
section?
Ok,
I
just
want
to.
Let
me
get
the
project
management
bullets
out
of
the
way
and
then
I'll
move
up
to
that.
Let's
see
one
thing
important
thing:
I
wanted
to
share
with
our
teams,
so
we
encourage
teams
to
meet
outside
the
semi-annual
big
dev
meeting.
A
So
if
you're
a
team
that
wants
to
get
together,
you
know
any
time
throughout
the
year.
Please
you
know
feel
free
to
schedule
that
if
you
need
some
space
Thomas
with
each
other,
we
don't
have
unlimited
funding
to
support
this,
but
you
know
we
may
be
able
to
spot
folks
here
and
there,
depending
on
you
know
how
much
your
meeting
so
keep
that
in
mind
team
needs.
You
know
work
with
your
team.
See
if
you
know
a
face-to-face
meeting
would
be
would
benefit
your
work.
A
A
All
right,
let's
see
question,
shall
we
continue
using
drop
paper
next
month,
maybe
in
a
chat
you
guys
can
put
like
a
thumbs-up
or
a
thumbs-down
or
at
the
beginning,
at
the
bottom
of
the
notes:
okay,
grant
things
cool,
okay,
thumbs
up
from
Sullivan.
Thank
you,
so
I
ravit,
those
I,
think
it's
working
really
well
and
we're
starting
to
discover.
Some
new
features,
for
example,
see,
was
able
to
drop
a
link
to
a
PR.
A
If
you
scroll
down
to
the
Jupiter
lab
section,
that's
pretty
handy,
so
you
know
that
there
are
some
other
really
cool
things
in
here
that
we
haven't
seen
yet
so
it'd
be
fun
to
give
it
another
month
to
to
test
and
if
something
better
comes
along
I'm,
not
sure
what
that
would
be.
Maybe
real-time
collaboration,
Jupiter
notebooks.
Maybe
we
can
move
to
that,
but
we
are
not
sure
when
that's
coming
yet
so
we
can
stick
with
Dropbox
paper
as
long
as
as
it's
working
unless
there's
something
better
that
folks
want
to
check
out.
A
Okay,
next
thing
is
well
I'm
working
on
the
annual
report
this
week,
so
we
send
out
an
annual
report
to
each
of
our
funding
agencies
or
funding
bodies,
foundations
twice
a
year
or
once
in
the
fall
and
then
once
a
minute
spring.
So
thanks
Carol,
great
okay.
So
that's
about
about
all
I'm
working
on
this
week
because
that's
going
to
take
some
time.
So
let
me
circle
back
to
Carol
as
you're
typing.
You
want
to
test
on
the
weekly
news
by
organization
section
and
just.
B
Briefly,
last
week's
in
folks
asked
about:
could
we
do
it?
The
news
that
we've
been
doing
for
Jupiter
hub
with
each
of
the
organization's,
so
I
ran
the
reports
for
each
of
them
this
week
and
it
uses
the
org
pulse
tool
that
libraries
that
I
io
uses
and
last
week
I
was
at
github
and
there
may
be
some
other
maintain
our
oriented
tools
coming
along
as
well,
but
for
now
that's
what
we
got
great
this.
A
A
Great,
so
team
team
team
leaves
check
that
out.
You
can
start
incorporating
that
into
your
report.
If
you
like
super
useful
information,
I
I
know
that
it
will
like
this
exists
in
some
commercial
products.
So
you
have
a
lot
of
commercial
products
these
days,
pulling
a
lot
of
open
source
tools
and
there's
something
like
this
in
a
couple:
project,
management
and
product
management,
commercial
tools.
So
I
think
this
is
a
really
good
direction
to
go
in
to
get
summary
of
what's
been
happening
over
the
week.
C
D
C
In
last
week
up-
and
it's
not-
we
don't
need
to
cover
it
now,
but
it's
just
a
couple
of
weeks
ago,
I
wrote
a
thing
to
automatically
search
your
bike
config
files,
wherever
they
happen
to
be
looking
into
the
Jeep,
your
past
stuff
and
stupider
com
search.
It's
now
on
IPI,
and
if
people
are
running
into
configuration
problems,
we
can
point
them
there.
I
don't
have
a
very
good
command
line
interface
figured
out
yet
then
you
just
need
you
executed
as
a
module
and
then
pass
them
an
argument.
But
you
know
that's
fine.
E
A
C
Actually
had
some
questions
about
ipython
that
relate
to
NB
convert
like
our
ipython,
so
at
ease
and
I,
and
some
others
were
talking
and
one
of
the
things
that
seems
to
be
missing
in
general,
from
the
don't
book
from
sort
of
publishing.
Point
of
view
is
easily
to
attach
captions
to
output
figures,
and
one
of
the
suggested
solutions
to
this
from
Matthias
was
creating
a
figure
class
in
ipython.
C
It
felt
that
then
the
notebook
would
know
how
to
intelligent
they
display,
but
in
which
case,
in
which
case
we
would
have
the
metadata
extraordinaires
part
of
the
object
itself,
which
could
include
the
caption,
which
then
and
be
convert
cuz
lincoln
jus.
Each
said
that
there
did
some
discussion
about
this.
Had
there
been
any
board
movement
when
I'd
look
for
it,
I
couldn't
see
too
much.
F
C
F
Can
touch
the
yet
to
with
the
current
trend
of
things
a
custom
mime
type
is,
it
seems
to
be
the
way
such
things
tend
to
be
going,
and
then
you
could
have
you
know
a
field
for
the
data,
a
field
for
the
captial
neck.
I
think
the
way
it
probably
would
have
been
implemented
before
was
a
multiple
representation
thing,
where
a
figure
would
have
maybe
an
HTML
representation,
that's
an
HTML
rendering
and
then
a
lot
like
representation
I.
F
C
Goods
I'd
appreciate,
oh,
but
the
idea
being
that,
by
using
a
custom
line
type,
what
you
do
is
you
just
establish
what
this
is,
rather
than
have
a
lot
of
encode.
Really
what
all
of
these
interpretations
are
it's
just.
This
is
a
thing
and
then
all
the
things
that
need
to
read
it
in
some
way
or
another
know
how
to
really
read
yeah.
F
G
C
C
A
E
So
I
am
try,
talking
I,
think
you
can.
You
can
hear
me
yeah
and
so
we're
closing
in
on
notebook
five-point.
Oh,
we
have
a
better
one
out
the
people
test.
You
can
install
that
from
pie
pie
and
does
a
few
usability
issues
that
Brian
highlighted
when
he
looked
over
it
and
so
we're
going
to
try
and
clear
those
up
and
as
a
question
from
a
panda's
developer,
who'd
like
us
to
to
change
something
in
the
new
default
table
style.
A
H
A
C
So
a
lot
of
my
time
last
week
was
spent
on
not
Indian
good
stuff,
but
Thomas
emerged
and
atomic
with
cutting
script.
Exporter
looks
good,
they're
known
as
anyone's
actually
tried
to
use
it
yet,
but
I
know
I.
Our
kernel
is
work
here
to
keep
it
and
I
have
for
their
like
in
terms
of
any
convert.
That's
the
main
thing
that
happens.
I
Yeah
Oh
lot
enough
this
week,
anyone
actually
contributed
a
full
requested,
knockers
back
to
add
Heidi
verse,
Bouchard
containers
there,
which
is
great
I,
didn't
know
that
was
a
kind
of
package,
the
dishes,
the
favor
Spanish.
That's
so
cool
Colonel
anyway
started
testing
against
no
replies.
There's
a
handful
of
legs
that
need
to
be
fixed
for
compatibility.
I
Someone
offered
to
introduce
a
title:
Colonel,
color
directly
to
Colonel
gateway
that
I've
directed
a
conversation
to
know
group
itself
as
I
think
that's
something
min
had
mentioned.
Why
has
it
always
positive
activity
tracking
it
yet?
And
it's
that's
the
direction
of
what
I
goin
on
in
favor
of
that
I
think
with
Colonel
gateways
to
do,
we
can
make
bringing
a
TI
change
and
take
out
the
activities
guy
that
we
had
implemented
over
there
and
favor
of
just
using
a
lot
for
notebook
I.
Don't
see
a
reason
why
we
use
in
two
separate
guys.
I
At
this,
for
that
section,
I
think
about
the
next
one
I
sort
of
inserted
this
it's
okay,
but
your
latest
Oprah
five
I
also
started
testing
various
dashboard
extensions
related
to
that,
most
of
them,
the
most
important
ones
that
for
layout
extension,
the
only
issue
I
hit
two
issues
ahead.
Where
is
falling
it,
which
was
probably
ban
on
us,
how
we
implemented
a
quick
setup
for
all
these
extensions.
Some
base
classes
moved
around,
but
the
simple
facts
and
it's
backwards
compatible
and
I
think
it
was
like
one
CSS,
styling
change.
I
It
was
causing
the
little
left
by
ourselves
to
show
up
in
the
dashboard,
but
otherwise
the
word
five
was
50,
so
that
was
great
news
restraining
having
to
dig
in
from
the
FB
CSS,
but
hopefully
just
worked,
and
then
the
other
ones
there,
the
butler's
extension
you
know
acting
up
a
dashboard
for
the
flip.
They
are
short
server.
It
can
now
start
using
Euler
API,
which,
when
it's
after
a
while
ago
for
those
it
should
learn
extension
I'm
here
anymore,
just
work
directly
with
no
provides
and
I
think
that
visited
episode.
I
I
reach
the
mailing
list.
People
could
chime
is
I
think
we
want
to
take
the
opportunity
of
this
release.
Vivek
your
bridge,
oldest
boy,
local
dashboard
option
that
was
inherited
that
we
marked
deprecated
almost
a
year
ago
and
we've
probably
pineapple,
is
I
found
it
even
works
on
board
with
latest
nitrogen.
So
little
notes
of
mailing
list
and
the
EMS
extension,
which
is
the
one
that
does
search,
also
has
a
bumblers.
I
We
can
now
reduce
the
by
malaria
guy
from
that
we're
happy
saying,
people
need
to
use
so
we're
five
enough,
because
that
were
an
older
releases
for
company
expansion.
Again,
it's
in
the
notice
the
case,
someone
who's
working
out
an
older
version
over
and
flexing
proof
extensions.
You
can
chime
in
and
say
please
over
the
wizard,
go
ahead,
what
an
open
57!
That's
what
it
amounts
to.
A
D
D
It's
just
the
new
packages
that
phosphor
has
and
before
we
started
on
that
and
last
week
we
did
a
bunch
of
a
lot
of
data
bug
fixes
some
of
them
that
have
been
quite
long
standing,
they're,
gone
and
also
Steve
did
a
pretty
substantial
refactor
of
the
way
render
my
work
and
the
way
that
the
models
that
notebook
uses
are
structured
and
standardized
a
lot
of
things.
In
fact,
we
have
a
new
pattern
that
we
want
to
apply
across
the
board.
D
We're
all,
basically
things
that
take
models
will
have
an
eye
model
interface
specified
in
there
widget
namespace
so
say
you
are
creating
a
fool
idiot
and
it's
sophisticated
enough
to
not
just
have
data.
I
should
be
done
it
you
actually
want
to
have
a
model,
then
you
create
a
namespace
called
sewage
it
and
inside
it
you
have
an
eye
model
interface
and
we
just
want
to
have
conventions
that
are
sort
of
predictable
across
the
board,
and
we
were
kind
of
being
haphazard
with
models.
D
A
G
J
J
That
turns
out
to
be
really
nice
and
nessa
fitted
some
small
fixes
after
we
merged
it
to
a
dirty
or
visible
and
the
reader
docs
rendering
and
the
env
viewer.
So
you
can
check
it
out.
Hopefully
we
will
release
in
release
candidate
today
and
curly
an
alchy
tomorrow,
because
I
mean
we
need
to
work
in
the
announcement
and
the.
Besides
that
we
have
created
a
Jupiter
widget
organization
that
will
be
the
recipient
for
the
sub
projects
of
widget.
So
there
are
lots
of
these.
J
I
buy
widgets
jupiter
jet
widget
widget
in
the
extension,
the
lab
extension,
the
widget
kima,
the
cookie
cutter,
a
sphinx
extension,
maybe
trade
that
and
so
I
also
wanted
to
give
a
heads
up
to
people
who
work
on
the
cartridges.
Maybe
this
would
be,
they
would
be
nice
for
this
project
to
be
moved
in
this
in
this
organization.
Oh.
J
A
J
Right
something
widgets
is
going
through
it,
a
big
split
I,
just
like
the
notebook
and
ago,
and
there
are
1
2,
3,
68
sub-projects,
so
yeah
that
will
land
there
and
I
also
wanted
to
ask
whether
people
who
know
about
it
think
it's
a
good
time
to
elect
the
trade
types
people
to
be
core
digital
thing
in
the
Jupiter
widget
or
so
trade
that
triple
the
Jupiter
incubator
project.
That
has
trade
types
for
side
pipes.
A
No
big
was
ok.
Let
me
say
that
I
think
that
the
creation
of
a
new
org
is
worth
advertising
beyond
the
Deaf
meeting.
So
if
we
could
get,
you
know
mailing
list
post
to
our
community
now
and
also
add
that
to
the
next
newsletter
I
think
that's
it's
worthwhile
to
communicate
to
the
community
when
we
create
new
orc,
we
got
well.
I
spoke
with
somebody
from
github
a
couple
weeks
ago
now,
and
he
said
this
they're
working
on
supporting
more
levels
within
the
github
hierarchy
in
each
org.
A
So
this
may
mean
that
at
some
point
we
can
bring
all
the
different
jupiter
orb
back
together
under
one
heading,
because
I
know
it's
really
important
to
be
able
to
have
more
nested
relationships
within
our
projects.
It's
also
harder
for
folks
to
track.
What's
going
on
with
the
project
when
we
have
like
this
mattering
of
orgs,
but
it
makes
it
makes
sense
right
to
continue
to
to
build
out
org
when
you
need
more
levels
to
keep
track
of
your
your
projects.
A
J
B
Wave
should
we
have
a
I
think
I
think
we
need
to
figure
out.
I
know
Sylvan
had
said
something
to
the
one
of
the
mailing
lists
about
which
repos
should
get
moved
over
and
I.
Think
probably
what
we
need
to
do
is
reach
some
consensus.
That
I
mean
I.
Think
personally,
all
things
that
are
related
to
widget
should
be
under
Jupiter
widgets,
but
I.
B
J
A
F
And
not
a
lot
of
exciting
development,
a
few
Jim
clean
up
something
something
working
with
you
on
testing
tool
for
some
of
the
authenticator
stuff,
so
that
we
can
feel
a
little
bit
more
confident
that
they're
doing
the
right
thing,
but
I've
been
getting
ready
for
goblins.
Haven't
made
a
lot
of
huge
amount
of
progress
myself
then
so
I
think
some
conversations
about
the
hub
shared
design
it'll,
probably
be
doing
a
lot
of
prototyping
on
one
element.
Berkeley
your
signal,
yeah.
B
And
karralys
and
then
the
other
thing
is,
we
did
get
somebody
filing
an
accessibility
issue
on
Jupiter
hub
and
rereading
back
through
it.
Actually,
a
lot
of
it
has
more
to
do
with
the
notebook
and
Jupiter
lab
and
how
somebody
who
is
visually
impaired
could
navigate
through
the
notebook
quickly.
It's
a
speech
so
I
dropped
a
testing
link
in
there
there's
also
more
information
on
AP
NAF.
But
at
some
point
we
probably
should
do
some
comprehensive
project
on
accessibility
and
I.
A
I'm
glad
you
brought
that
up,
we
do
have
the
data.
Eight
folks
are
looking
into
accessibility
issues
on
not
issues
but
accessibility
around
the
notebook.
So
there
will
be
a
test
here
on
I.
Think
it's
march,
six
I
think
we'll
we
have
a
blind
individual
who's
going
to
be
going
through
the
notebook
and
it's
going
to
try
to
navigate
on
different
parts
of
it,
so
we're
trying
to
get
that
recorded
to
make
available
to
the
team.
G
B
You
know
they
were
quiet,
but
there
were,
you
know
a
few
people
and
thank
you
too
Pete
and
Steve
for
pitching
in
most
of
the
speaker.
Outreach
we'll
have
more
of
an
impact
next
year
versus
this
year,
but
you
know
continuing
to
have
the
word
out
on
Twitter
and
passing
it
on.
Our
networks
are
going
to
be
important
than
just
encouraging
people
when
they
have
a
question.
Yeah
submit
a
talk.
You
know
you
never
know.
Yeah
thanks.
Everybody
yeah.
A
Okay,
unless
they
call
for
proposals
for
sighs,
I
opened
that
we
support
last
I
believe
and
registration
opens
next
week.
I'm
with
that
pie
day,
pi
data
Amsterdam
coming
up
and
pi
day
to
London
coming
up
in
May
great.
So
these
are
the
action
items
that
Ian
jotted
down
my
face.
Mike
is
scheming
about
an
eye
python
class
notebook
metadata
field
that
holds
caption
information,
Ricky
for
figures,
ping
em
with
ideas
or
prior
art.
Fernando.
A
E
A
I
think
I
didn't
hear
that
at
all
okay
I
guess
we
gotta
read:
look
alright
thanks,
Thomas,
alright,
so
releases
this
week.
Let's
see
was
released
you
for
a
client,
five
point,
0
and
B
format.
4.3
should
be
released
soon:
ipython
5.3,
every
dime
0.2
I,
pirate
six-point
Oh
we'll
have
a
release
candidate
out
in
the
next
day
or
two
when
I
say
we
I
mean
Jason
and
Sylvan
Jupiter,
gijs
widgets,
2.1
and
widgets
and
the
extension
two
point.
Oh
that's
the
Jupiter
widget
schema.
A
So
we
have
a
beta
testing
notebook
five
point:
O
went
01
or
beta
1
and
that's
all
for
the
releases.
Let's
see
everybody's
like
in
the
drop
box,
so
really
happy
to
see
that
good,
let's
keep
using
it.
It's
working,
that's
my
boat,
great
okay,
I
like
seeing
all
the
thumbs
up
great.
Does
anyone
have
anything
they'd
like
to
add
anyone
else?
Have
anything
they'd
like
to
add
I
know
some
folks
aren't
part
of
the
usual
run
through
on
the
notes,
but
please
feel
free
to
speak
up
now.
A
Currently,
no
so
what
I've
been
doing
with
the
notes,
as
we've
been
experimenting
with
new
platforms,
is
dropping
a
link
into
our
hack
pad
note.
So
at
least
folks
who
are
used
to
going
to
hack
pad
can
can
link
out
to
either
pad
and
and
rock
paper.
But
I
do
like
the
idea
so
that
they're
here's
the
question
that
that
came
up.
What
which
set
of
notes
do
we
archive?
Do
we
archived
and
notes
from
the
meeting
that
we
created
or
the
notes
that
were
posted
on
the
mailing
list?
Oh.
