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).
A
B
Think
there.
C
B
A
Yeah,
it
could
be
okay.
A
A
A
Okay,
okay,
yeah
last
time
we
met,
we
didn't.
We
just
talked
about
some
automatic
context,
handling
issues
that
I
had
and
not
much
more
so
maybe
we
can
and
for
today
we
have
also.
A
Yeah,
I
released
a
version
on
tuesday
that
had
some
interesting
code.
One
of
them
was
a
very
bad
issue.
We
had
that
we
we
were
incorrectly
setting
the
start
time
of
the
spans
to
the
time
where
the
spam
builder
was
created
instead
of
using
the
the
start
of
the
span,
so
that
that
was
a
problem
if
you
were
waiting
for
the
spam
builder
to
start
the
spam
after
for
a
long
time.
A
A
Yeah,
so
it
was
just
a
one-line
problem,
more
or
less
it
just
was
a
value
that
shouldn't
be
initialized
and
it
was
being
initialized
erroneously.
I
don't
know
why.
From
the
beginning,
I
would
say
that
that
has
been
broken
forever
for
for
a
really
long
time,
so,
but
probably
because
it
doesn't
create
one
character,
change,
yeah,
more
or
less.
It
was
just
putting
no
not
in
insulation
at
eight,
because
it
was
yeah
the.
If
you
create
the
spam
builder
directly
and
start
the
span.
A
A
Second,
instead
of
one
millisecond
that
I
was
expecting
and
really
weird
things,
so
it
took
me
some
some
days
to
realize
that
it
was
not
my
ntp
clock,
doing
nasty
things,
but
it
was
in
the
library
so
and
there
were
also
some
stuff
that
that
was
in
the
project,
one
very
interesting
one
that
it
was
donated,
the
exporter
decorator,
so
it
serializes
your
sponsor
your
metrics
to
disk
and
it
after
that
it
uploads
those
those
things
from
your
dish
to
the
original
exporter,
where
you
create
that
you
create.
A
So
it's
using
the
same
thing
that
I
was
using
for
the
for
the
data
log
exporter
that
it
was
saving
to
disk
and
and
exporting
later
so
it
used
that
to
wrap
any
exporter.
So
you
can
use
that
directly.
Now
there
is
some
sample
code
in
that
project.
A
I
don't
know
if
you
realize,
but
the
project
which
one
is
this
yeah.
Let
me
it's
in
the
exporters
it's
in
the
release
notes,
but
in
the
exporters
the
name
is
persistence.
A
It's
it
it's
a
sporter,
but
it's
in
reality.
It
just
decorates
another
exporter
and
pre-safe
things
to
disk.
So
in
case
you
have
a
mobile
phone
that
just
loses
connection
because
you
get
into
you,
you
know
in
an
elevator
or
somewhere
and
you
lose
connection,
you
won't
lose
those
spans
exporting
or
if
just
the
you
lose
connection
for
a
long
time.
You
and
you
end
the
application.
You
won't
lose
that
information,
because
it
will
be
serializing
disk
so
that
that's
really
useful
for
mobile
development.
A
Also,
so
I
I
thought
that
the
back
was
so
big
in
reality,
and
this
persistent
thing
was
also
quite
interesting,
so
it
I
released
a
version
so
yeah,
so
that
one
and
what
and
from
my
site
I
don't
have
any
other.
B
A
So
it
it
implements
codable
protocol.
So
you
can
save
it.
However,
you
want-
and
the
other
is
the
decorator
itself
that
just
as
exporter
you,
it
takes
the
span
data
serialize
it
to.
I
think
it's
to
json,
it
saves
to
disk,
and
it
has
another
thread
that
just
read
from
disk
from
time
to
time
and
uploads
the
results.
But
if
that
thread
loses
connection,
it
will
wait
until
it
gets
connection
again
or
the
next
time.
A
You
launch
your
app,
so
you
can
recover
the
file
saved
to
disk,
so
you
you
suddenly
lose
expanse,
and
the
good
thing
is
that
it
works
for
any
exporter
that
we
that
we
have
in
in
open
telemetry,
because
that's
wraps
it
up
so
and
it
was
a
yeah.
It
was
a
developer
from
autodesk
that
he
received
that
and
wanted
to
donate
the
code.
A
A
I
will
try
some
more
things,
but
maybe
we
cannot
handle
that
correctly
inside
the
asynchronous
task.
We
can
just
get
one
level
of
the
task
and
after
that
we
can
probably
will
implement
some
kind
of
stack
or
something
like
that.
So
it's
a
best
guess
thing:
you're
gonna
have
several
parallel
tasks
that
will
linear
it
correctly,
but
I
don't
think
I
can
get
much
better
than
that
with
the
current
with
the
things
is
because
I
don't
know
if
you
have
checked
about
that.
I
I
told
me
not
about
this
last
meeting.
A
So
you
cannot
change
this
value
in
the
in
the
stack
and
you
cannot
do
anything
with
that.
So
it's
like
a
explicit
context
so
that
you
have
to
explicitly
change
the
context
and
it's
safe
in
the
stack.
You
cannot
modify
that
from
outside,
so
it
just
gets
clean
up
when
the
stack
when
the
function
just
gets
out
of
the
scope
and
that
that
kind
of
things,
so
you
can
modify
the
stack
for
all
of
them.
But
if
another
is
one
is
created,
you
cannot
create
another
stack
for
new
things.
A
Whenever
you
create
expand,
we
we
currently
create
a
new
context
with
when
span
starts
and
it's
an
active
span.
But
here
you
cannot
do
that.
You
cannot
create
that
context
area
if
you
have
not
created
code
code
directly
for
that.
So
if
or
you
have
that
explicitly
in
the
original
code
or
you're
going
to
create
that
so
right
right,
it's
it's!
I!
I
don't
think
there
is
a
solution
for
that.
A
One
for
all
the
asynchronous
tasks,
so
at
least
you
have
a
parent
or
something
like
that
or
yeah.
That's,
I
think
it's
the
best
approach
having
something
that
having
some
span
when,
where
you
can
put
your
your
expense
at
child,
if
you,
if
they
have
a
parent,
that's
the
only
thing.
I
think
we
will
get
from
this
stuff.
A
C
Yeah,
I
haven't
had
a
chance
to
look
at
that.
Your
work
yet
so
I'll
take
try
to
take
a
look
at
it
this
week
and
see
if
I
can
think
of
anything.
A
Yeah
I
created
some
tests,
yes
to
validate
that
things
were
working
and
yeah,
and
I
found
many
many
many
issues
with
the
asynchronous
thing.
In
fact,
I
think
it's
the
code,
I
added
is
basically
not
doing
anything.
A
It
would
work
more
or
less
without
the
code
that
I
did
for
handling
that
because
somewhat
works,
but
it
doesn't.
If
you
have
several
a
synchronous
task,
it
won't
and
in
parallel
it
will
lose
the
the
context
they
will
be
just
fighting
for
the
same
value.
A
A
No,
no,
the
latest
13.1
has
that
when
running
in
ios
15.
A
Yes,
it
will
work
in
a
in
a
in
a
iphone
simulator
with
ios
15,
but
the
newest
beta
of
xcode
has
it
working
and
running
in
ios,
13
and
mac
os,
10
15,
or
something
like
that,
so
it
will
run.
If
you
have
the
latest
beta,
you
can
run
that
on
your
mac
instead
of
using
a
simulator,
but
whatever
you
prefer.
If
you
are
with
13,
you
can
run
directly
in
a
similar
13.1.
A
No,
you
have
13.
You
can
run
that
already
in
a
simulator,
13.1
adds
mac,
but
big
sur
only
and
the
next
beta
will
add
the
all
the
rest
of
the
systems,
but
yeah.
That's
the
that's
the
thing
that
I
I
didn't
have
much
time
this
week,
but
yeah.
I
don't
think
I
will
be
able
to
find
a
solution.
I
am
going
to
work
till
actually
on
this,
probably
starting
from
tomorrow,
for
at
least
two
or
three
days
just
to
try
to
get
a
solution
or
something
better
than
what
we
have
now
at
least.
C
A
Okay,
nice,
I
don't
know
if
I
uploaded
the
latest
test.
I
think
I
did
sometimes
that
won't
work,
because
so
it's
better
in
you
know
I
uploaded
a
branch
with
that
work.
I
will
check
that.
I
I
uploaded
the
latest
test,
at
least
so
you
can
see
how
it
fails
with
the
different
approaches.
A
A
C
A
C
Okay,
I
don't
really
have
that
option
unless
you
want
to
learn
llvm,
maybe
you
can
hook
into
that
somehow
and
inject
something.
A
I
don't
I
you
don't
have
a
run
time
there
I
mean
you
know
it's
really.
I
have
tried
anything.
I
could
think
about
solving
that,
but
then
yeah
I
I
don't
think
we
can
do
anything,
because
it's
in
a
stack
that
you
cannot
create
a
new
stack.
A
A
Yeah,
that's
right,
and-
and
you
cannot,
if
you
create
a
span
inside,
you
cannot
create
another
context
value
here
for
the
now
on,
because
you
have
the
same
stack
and
the
value
is
in
the
stack.
It's
not.
You
cannot
create
another
stack
after
you
create
a
spam.
That
was
the
first
thing.
The
last
thing
I
tried
creating
a
stack
new
as
if
you
created
a
new
task
when
you
create
a
spam,
so
you
have
a
parent
task.
A
A
Any
idea
is
good,
so
we
we
because
if
not,
we
are
not
gonna
solve
that
problem
or
they
solve
the
activity
thing
that
they
broke
with
this
task
because
it
was
working
with
activity
really
well
and
they
don't
support
the
activity
values
inside
a
synchronous
task.
That's
a
pity.
B
A
A
They
said
they
were
going
to
check
the
code
and
and
yeah
and-
and
they
never
appeared
again
so
yeah.
I
don't
know.
A
A
A
Okay,
yeah,
I
will
take
this.
Oh
it's
elastic
block,
so
bryce
yeah
yeah,
but
it
might
have,
has
has
direct
knowledge
or
great.
Is
we
have
an
insider
here.
A
C
A
You
cannot
get
that
for
free.
It's
really
difficult,
yeah
great.
B
A
Okay,
any
other
topic
you
can
have.
B
B
So
but
it's
crazy,
it's
kind
of
crazy.
The
number
of
people
around
me.
You
know
yeah
people
are
masked
up,
but
you
know,
and
they,
when
you
go
to
all
these
places,
to
eat
yeah
everything
is
off
right,
you're,
sitting
very
close
to
other
people,
so.
B
B
A
Yeah
they
they
released
their
own
ram
series.
B
B
A
Okay,
so
then,
if
there
are
no
more
topics
enjoy
your
week
in
vegas,
you
know
you
don't
have
to
tell
anything
about
what
happens
there.
