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
Let's
start
and
that's
week,
I
was
I
was
continuing
and
testing
the
since
I
rise
drop,
D
be
under
ten.
That
I
can
have
a
the
ligands
it
was
caused
by
well.
I
can
reproduce
the
perform
the
regression
using
the
building
test
benchmark
provided
by
my
sister
and
from
my
Marquette
this
morning.
A
B
B
Make
the
eighty
somebody
to
works?
It's
because
the
sister
check
the
SMP
counter.
If
it's
only
a
bigger
than
one,
they
created
a
SMP
message
queue
so
for
us
I.
Just
we
just
use
SP
only
one
car,
so
I
just
a
temporary
set
it.
It
is
equal
or
bigger
than
one.
We
always
created
a
message
queue,
so
the
eighty
submitted
to
works
and
I
in
the
when
the
OSD
called
a
lien.
Gustaf
I
create
your
own
register,
our
own
committee.
B
So
when
the
blue
stop
saying
this
thread
running
on
that
I'll
meet
from
commit
function,
ice
beside
the
promise
set
value
and
then
in
this
is
our
side
that
we
we
called
the
promise,
get
value.
So
when
that
finishes
right
side
value,
then
the
le
stop
will
get
value
then
return
to
the
OSD,
so
the
the
den
function
will
be
called
will
be
continued
at
Puri
in
the
PG
at
the
period
stated
it
register
its
own
commit.
B
So
there
there
are
two
unka
beat
register.
What
is
the
PG
fury
his
own
uncommitted?
Another
is
its
my
own
Committee
on
Committee
for
the
guaranteed
the
blue
star,
finished
and.
B
C
B
C
B
C
B
C
Other
words,
you
can't
just
run
them
blindly
because
they
expect
to
be
run
in
that
context,
but
sorry
I,
shouldn't
use
that
word.
They
expect
to
be
run
in
the
same
thread
that
the
OSD
ism',
because
they're
accessing
the
same
memory
right.
So
you
have
to
take
care
of
hiding
that
hurt.
The
blue
store
will
only
ever
see
your
wrapper.
Your
wrapper
has
to
take
care
of
running
the
things
that
were
queued
on
the
transaction
register.
Sorry.
B
C
C
A
C
B
B
B
C
You
need
to
wrap
it
so
that
the
off
look
at
your
coat,
but
the
answer
is
that
what
blue
store
is
seeing
should
be
deletable
because
it
ran
it
and
that's
what
contacts
are
right.
So
the
action
of
running
that
context
needs
to
trigger
behavior
on
the
sea.
Star
side
that
runs
the
wheel.
Callback
blue
store
should
never
have
seen
the
real
callback.
A
That,
for
me,
I
just
want
to
note
that
the
native
the
native
version
of
Roscoe
could
could
be
complete,
can't
be
competing
with
your
own
eyes.
The
rocks
who
stock,
if
the
performance
better
the
nice
approve
the
will
pay
us
a
lot
of
time
before
we
have
as
a
native
version.
If
it
spelled
out,
the
native
version
cannot
the
performance,
the
native
version
cannot
beat,
or
at
least
on
par
with
that
night
it
will
be
deprecated.
B
C
Hang
on
a
sec,
I
think
we're
getting
out
of
ourselves.
It
sounds
like
we're
pretty
close
on
the
alien
eyes
booster,
so
it's
probably
worth
going
ahead
and
finishing
it
and
see
we're
and
seeing
where
we
are
I
think
we're
on
a
good
path.
For
now.
B
Only
a
pin
to
unzip
your
car
and
just
a
critter
once
rider
particles
rider,
so
the
booster
will
produce
many
Sabbath
posix
Rider
and
it
seems
I
just
want
the
finish
right,
also
running
in
the
in
the
CBO
car
I
painted
it
that's
right,
so
it
seems
our
default.
The
substratum!
Well,
all
of
them
scheduled
understands
if
you're
calm.
So
maybe
we
need
to
create
a
mouse.
D
Hello
last
week:
well,
let's
start
from
the
aerator
stuff
it
to
me.
The
the
perf
check
brought
has
arrived,
that
we
have
a
failed
to
build
from
cells
issue,
but
only
on
a
newer
version
of
VCC
on
this
is
nine
determine
out
that
a
relative
who
was
was
making
making
use
of
had
very
likely
a
DCC
back
Thanksgiving
for
idea
for
for
fixing
up
I,
first
I
prosthetics
to
the
branch,
also
in
things
related
to
performance
testing
to
peers.
One
is
one
actually
switches
the
built
type
release
for
the
check,
Jenkins
job.
D
That's
the
one-liner
emerged
yesterday.
I'm
not
well
I'm,
not
sure
whether
we
need
to
learn
to
switch
the
default
type
of
built
for
this
America
site.
Actually,
the
Eid
human-built
type
option
appended
here,
Gertz
priority
over
the
default
data
we
have
inducing
a
second
PR.
Second
issue
is
related
to
difficult.
We
are
at
party
that
the
perfect
that
is
actually
doing
commercial
square,
shall
you.
D
D
D
D
Switched
I
switched
the
path,
the
path
test,
thank
his
job
to
do
to
the
random
reads:
instead
of
sequential
routes
right
now,
the
issue
is
related
to
how
Raiders
bench
in
generic
operates.
Basically,
the
number
that
the
number
of
reads
issued
in
support
configuration
is
very
limited
on
my
machine.
It
lasts
the
entire
run
last
in
half.
Second
I
pressed
the
fix
for
it.
D
E
E
Will
it
still
needs
cleanup
and
then
I
push
it
over
view,
and
but
most
of
the
bottom
cleaning
now
is
mostly
work:
company
understanding,
performance
testing
and
doing
performance
tests,
probably
on
one
of
the
labs,
not
on
my
laptop
and
this.
This
will
be
the
main
focus
of
what
I'm
do
and
we're
doing.
E
Just
one
note
I'm
like
everybody
here
is:
we
are
on
the
vacation
until
the
22nd
more
or
less
today
today
is
the
holiday,
so
we
are
more
or
less
absent
until
the
22nd,
so
I
don't
expect
much
to
be
done
until
the
big,
more
or
less
the
end
of
the
month.
So
that's
from
my
side,
I
hope
to
be
able
to
push
that
PR
in
a
few
opening
before
the
end
of
the
month.
E
A
C
C
That
tells
you
why
officer
blocked
and
the
same
time
adding
the
object,
context,
ref
and
right
now,
I'm
working
on
I
extracted
the
readwrite
state,
lock
state
machine
from
object
context
in
classic
OST,
because
it's
a
giant
ball
of
special
logic
that
I
didn't
really
want
to
duplicate,
but
I
left
all
of
the
stuff
about
queuing
up,
request,
rest
and
such
over
in
primary
long,
PG
or
whatever,
so
that
we
don't
have
to
deal
with
any
of
that.
C
Crap,
instead
futures
will
just
try
to
obtain
a
lock
of
the
right
kind
on
the
object
on
text,
and
it
will
be
I'll
get
a
future
back
and
they'll
suspend
until
they
get
to
keep
going
so
it'll
be
a
little
bit
more
ergonomic
than
classic
OST.
Rather
I
expect
to
have
at
least
a
reasonably
functional
version
of
this
bit
of
the
past
series.
By
like
Monday.
D
A
C
C
Not
gonna
produce
anything
new
for
this.
It's
just
a
set
day,
so
I
figured
I'd
just
give
a
brief
overview
of
the
project
and
like
well
what
what
its
purpose
isn't
where
we
are,
it's
mostly
users.
So
it's
not
so
much
like
developers.
This
is
more
here's
something
you
may
be
interested
in.
That's
probably
a
year
to
two
years
down
down
the
pipe.
C
C
D
D
D
F
F
F
Maybe
it
is
a
like
connection.
Timeout
like
if
the
socket
is
is,
is
blocked
like
we
cannot
send
anything
out
or
and
read,
read
anything
from
the
socket
it
just
stopped
there
and
there
there
is
time
outs
mechanism
in
a
sink
messengers,
so
I
think
I
also
need
to
add
it
to
crimson
to
detect
the
network
issue
during
ready
state
and
if
it
time
out
it
needs
to
reconnect
again.
Like
yes
and
loop
back
like
so
on
some
thumb
like.
F
C
F
C
At
the
it
depends
on
how
we
choose
to
implement
erasure
coding,
but
as
a
shortcut
and
because
it
was
there
and
because
I
was
lazy.
When
I
was
implementing
the
original
easy
back
end.
You'll
notice
the
primary
actually
sends
messages
to
itself
mm-hmm,
but
it
doesn't
really
have
to
reason
about
the
difference
between
primaries
and
replicas
and
because
it
actually
turns
out
to
be
a
fairly
convenient
way
to
separate
the
the
were
queuing.
B
E
C
A
A
Before
conclusion,
sister
stand
up,
I
just
want
to
remind
remind
us
that,
with
I
said,
I
published
the
two
to
play
at
wind,
the
Crimson
plan,
another
plan,
the
former
Easter,
is
the
includes
the
timeline
of
the
different
action
table
action
items.
So
probably
we
need
to
read
report
eyes
our
taxed
accordingly.
Some
of
them
I
have
a
very
short
discussion
with
the
the
church
which
encouraged
me
to
to
to
prioritize
some
of
them
so
to
to
design
which
which
one
of
them
can
can
be
completed
before
before
octopus.
C
Suggestion
it
might
be
easier
just
to
just
to
have
people
commit
to
the
get
up.
One
I
didn't
to
make
it
hard
to
update
I,
don't
think
it
should
require
any
any
reviews
or
anything
I
think
you
should
just
be
able
to
modify
even
commit
immediately.
That
way,
there's
only
one
version
of
the
document,
not
too
just.
C
A
This
is
the
one
without
the
timeline,
because
the
timeline
is
subject
to
change
and
they're
still
under
discussion.
If
you
wanted
to
add
in
more
more
fine-grained
the
object,
pockets
pretty
feel
free
to
edit
and
push
it
I
believe
everyone
know
that
should
have
the
privilege
to
do
to
push
it
right.
Anyone.
A
F
A
C
A
Okay,
that's
a
button,
that'll
be
I,
I
would
say,
that'll
be
intrusive
change,
so
I
my
plan
to
to
replicate
the
year.
The
first
first
step
I
think
I
can
I
can
think
of
is
to
to
clean
up
the
existing
country
to
Porat
and
restore
to
make
it
more
more
readable
and
the
second
step,
that's
what
I'm
doing
now.
The
second
step,
I
think
is
to
they
subject
to
change
it
could,
depending
on
discussion
next
step,
is
to
and
replicated
them
like
what
we
did
on
memory
store,
yeah.
C
I
would
argue
that
that's
an
extremely
bad
approach,
I
think
any
time
you
copy
code
like
that,
especially
something
as
complicated
as
blue,
store
or
never
gonna
be
able
to
keep
up
with
the
book
with
the
bugs.
It
means
everyone
think
it's
distant
blue
store
has
to
be
copied
over
and
fixed.
On
the
other
side,
too.
The
only
way
you
des
my
contention
is
that
the
only
way
this
project
works
is,
if
you
extract
the
parts
that
care
about
the
difference
between
POSIX
and
C
store
into
a
plugin
infrastructure,
not
on
like
proxy.
A
C
C
C
No
I
don't
think
we
can
support
two
versions
of
blue
store,
I
think
it's
worth
doing
this
correctly
and
extracting
a
plug
in
infrastructure
and
actually,
when
you
guys
are
doing
general
things
reporting
overflowed
from
classic.
You
should
think
in
these
terms,
try
not
to
pour
it
over.
Try
not
to
copy
anything.
That's
a
genuinely
complicated
like
do
the
work
tree,
thakura.
C
They
have
the
same
word
attached
to
them,
but
they
accomplish
different
things,
which
is
not
to
say
that
we
couldn't
go
that
approach.
I
actually
did
think
about
that,
a
while
back,
which
is
why
I
built
like
a
beast,
are
agnostic
futures
thing.
So
we
could
create
like
a
worker
like
future
or
create
this,
like
a
version
of
like
the
OST
thread,
pool
that
replicates
some
of
this
bit.
Behavior
that
that's
an
approach
to
I'm
open
to
that
also,
but
for
blue
store
I
suspect
that
it
won't
be
as
bad
I
think.
C
C
A
C
Rox
DB
or
blue
store
is
similar
to
that
it
has
some
threads.
It
has
some
new
taxes
and
it
has
a
few
other
things,
but
if
we
can
identify
all
of
those
things
and
create
a
plug-in
infrastructure
for
it,
then
we
can
make
blue
store
itself
agnostic
about
which
environments
running
engine
it's
running
in
and
then
classic
and
crimson
would
simply
provide
their
own
implementation
same
way
same
thing,
we're
doing
for
the
same
thing,
you're
doing
for
watch,
TV.
E
E
C
Unlikely
that
they
will,
because
of
how
inefficient
blue
star
already
is,
but
I
agree.
That
is
a
design
constraint,
but
remember
what
we're
talking
about
here
is
at
worst,
like
an
expert
in
direction
for
certain
POSIX
calls
that
we're
already
going
to
be
syscalls
and
I'm
having
trouble
seeing
that
as
a
major
performance
problem,
yeah.
E
C
E
C
A
No
I,
rather
than
not
actually
I'm
I've,
been
talking
myself.
Thinking
about
to
copy
Bristow
will
be
be
a
pain
because
the
III
was
a
keeping
and
now
I
eyes
on
the
development.
Recent
development
of
Pluto,
yeah
I
think
I
can
really
keep
memory
also,
so
it
it
would
be
a
nightmare
if
we
wanted
to
keep
trying
to
catch
a
flying.
Arrow
like
boost
or
yeah.
C
We'll
never
be
able
to
do
it
plus
there
are
some.
There
are
some
fringe
benefits
to
this
to
it's
a
lot
easier
to
test
for
thread
for
threading
bugs
if
all
the
threading
libraries
are
factored
out
like
you
can
create
testing
mocks
that
make
it
a
lot
easier
to
surface
bugs
like
that.
So
there
will
be
fringe
benefits
for
people
that
aren't
us.
C
C
A
C
A
Yes,
that's
the
question.
Latency
is
much
higher
than
than
playing
system
called.
It's
a
plane
system
call
took
it
like
take
like
two
two
or
three
microsecond
when
it
come
to
a
right
driven
by
reactor.
It's
like,
like
$10,000,
microsecond,
I'm,
still
looking
at
it.
Why
hi
you
can
reproduce
this
applet
using
the
the
the
iostream
perfect
over
I
PI
C
star,
equal.
A
C
E
E
C
E
Okay,
because
that's
if
you
ever
ask
the
questions
in
ela
is
a
few
weeks
ago
about
it,
I
was
trying
to
understand
why
we
have
so
many
contexts,
which
is,
if
only
if
we
are
guaranteed
the
system
is
never
interrupted
by
the
alien
fridge
we
are,
we
gonna
tell
you
using
affinity
or
whatever
that
is
listen.
Okay,.
C
C
E
C
So,
if
they're
all
pin
to
the
same
core,
there
will
actually
there
will
be
actual
contact
switches
if
they're
not
which
they
shouldn't
be
because
or
there
should
be,
because
none
of
them
are
gonna
consume
a
whole
core.
Let
me
put
it
that
it
that
way,
so
for
them
all
to
be
pin
to
their
own
course.
That's
that
they
never
go
to
go
to
sleep
will
be
wasting
like
six
times.
The
CPU
that
we
need
to,
in
other
words,
blue
store,
actually
uses
the
OS
as
a
scheduler.
C
If
that
helps
okay,
what
we're
talking
about
with
native
C
star
here
or
native
native
file
user
is
C
star.
Has
this
trick
where
you
can
run
regular
synchronous
code
in
the
sea
star
reactor
and
when
you
call
a
blocking
operation
on
the
future,
T
star
will
transparently
swap
out
the
stack
and
move
on
with
its
life.
It's
not
a
releasing.
D
C
D
Not
it's
just
a
greener
threat.
Implementation
of
Fred
Inc
made
entire
starladder
it's
by
Z.
It
basis
on
a
absurd
jump,
long
jump
all
that
stuff
that
actually
records
and
three
stores
you're
stuck.
The
question
here
may
be
related
about
whether
in
sister,
our
stuck
the
content
we
need
to
restore,
we
need
to
save
is
bigger,
is
larger
than
in
case
of
running
blue
stir
inside
classic
USD.
That
might
be
one
issue,
but
I'm
not
sure
whether
the
person
is
a
problem
here
and.
C
Do
a
library
map
function
into
an
indirect
call
on,
and
that
has
a
cost,
but
it's
not
a
big
one,
given
that
most
of
these
things
actually
do
cause
system
calls
I
think
it's
a
worthwhile
engineering
investment
to
see
if
it
actually
does
cause
problems.
If
it
does,
then
yeah,
we
got
to
get
clever,
but.
A
C
C
C
So
if
the
assumption
is
that
you
have
some
kind
of
fast,
persistent
or
non
persistent
fronting
cache
with
some
kind
of
sequential
optimized
not
append
only
but
append
optimized
slower
to
that,
it's
not
totally
clear
to
me
that
zone
based
nvme
is
different
from
hard
disk,
faster
yeah,
but
not
necessarily
different.
The
most
obvious
difference
is
in
random:
read
access.
E
So
what
what
we
are
back
to
is
that
it
is
a
viable
option
to
have
to
not
be
need
to
maintain
two
versions
of
blue
stone
in
the
future
remain
only
with
our
sister
well-conceived.
This
is
okay,
and
this
is
what
I'm
saying
is
that
if
this
is
a
valuable
option,
maybe
it's
still
a
viable
option
for
the
time
being,
they
do
maintain
maintaining
two
versions
of
bluestone,
which
is
much
much
simpler
than
just
changing.
Yeah,
okay,.
C
A
C
C
That
is,
if
I
mean
it
may
not
be
hard
okay,
but
the
real
question
is
we're
gonna
start
developing
an
actual
design
for
c-store
by
like
December
right
so
pretty
early
in
that
process
we
will
have
started
prototyping
things
and
we
will
know
whether
this
design,
because
we're
not
going
to
choose
we're
not
going
to
make
choices,
hurt
the
high-performance
case
just
to
support
it
hard
disks.
So
we
should
know
pretty
early
on
if
we
can
actually
get.
If
we
can
make
everything
happy
right,
it's
we
may
encounter
something
early,
that's
like!
Oh!
A
Think
your
work
is
very
important
because
it's
it's
the
alien
light
blue,
so
is
a
pin,
we're
tested
and
it's
performance
can
be
granted
at
most.
My
my
work
is
just
to
to
elimate
eliminated
the
effort
in
the
long
term
for
for
making
to
stack,
but
in
practice,
impractical.
We
need
to
do
because
we
will
maintain
the
classical
toi
hand
and
the
Crimson
ability
or
like
like,
like
Sam
mentioned,
would
it
be
like,
like
more
than
five
years
so
I'm
I
mean
magining
the
thing
after
the
five
years?
A
Something
like
that
and
also
it
will
be
paying
to
to
you
to
use
this
to
put
stack
in
the
one
plication
that
would
be
very
difficult
to
depart
to
depart
because
one
of
them
two
of
them,
have
different
expectations.
For
example,
one
of
them
are
using
the
classical
is
in
locking
another
one.
You
will
be
using
the
little
login.
C
C
A
A
A
C
E
C
Express
memory
operations
from
the
primary
of
the
replica:
that's
what
I
want?
Okay,
no
seriously
you
could
like
if
the
primary
the
replicas
have
the
replica
can
say:
I
have
reserved
a
gigabyte
of
space
for
you,
starting
at
this
offset
on
this
PCI
Express
device.
Please
dump
any
replicated
operation.
You
want
to
do
that
pew
in
order
and
don't
wait
for
me
to
acknowledge
it
right,
then
all
you
have
to
do
on
startup
or
whatever
the
peering
state
changes
over
is
make
sure
you
caught
yourself
up
on
all
these
logs.
Yet
you
didn't
notice.
C
C
It's
not
just
that
the
replica
in
the
primary
need
a
protocol
set
up
so
that
they
can
communicate
about
how
much
buffer
is
left
and
that
kind
of
stuff
and
there's
recovery
stuff.
That
needs
to
be
worried
about,
and
when
you
flip
over
the
peering
state,
you
have
to
bound
how
much
work
has
to
be
done,
or
else
you
could
create
some
idiotic
amount
of
curing
latency,
but
I
mean
this
is
all
doable
yeah,
probably
further
out.
C
C
For
the
for
the
record,
this
isn't
an
early
design
goal,
but
it's
things
like
this
like
we
might.
There
are
other
capabilities
of
nvme
that
we
that
we
do
care
about,
like
the
zoo
and
nvme
devices
are
gonna,
be
a
lot
cheaper
because
there's
no
flash
layer,
there's
no
FTL
layer
and
for
industry
reasons
we
probably
have
to
forget
that
immediately,
so
that
kind
of
thing
does
breed
hard
requirements.
A
A
C
Like
they're,
potentially
a
lot
cheaper
and
a
lot
faster,
essentially,
it
eliminates
the
entire
blast.
Translation
layer
that
current
random
right
SSDs
have
to
maintain.
All
they
have
to
maintain
is
a
memory
of
how
many
rights
each
zone
is
seen
and
the
current
right
pointer
in
each
zone.
That's
all
the
SSD
is
responsible
for
C
store
would
be
responsible
for
everything
else.
We're
leveling,
remembering
where
it
put
stuff
which
zones
are
open,
which
ones
are
closed,
how
full
they
are
all
that
stuff.
Oh.
D
E
C
The
thing
is:
we're
spending
a
lot
of
that
CPU
anyway.
Keep
in
mind,
we
already
maintain
offsets
for
stuff
right.
Blue
store
already
has
offsets
for
its
data
blocks.
The
only
problem
with
a
current
SSD
is
that
there's
a
second
offset
in
the
SSD
right.
We
pay
it
again
for
some
reason
and
for
performance
reasons
on
even
a
current
SSD.
A
C
What
we
do
is
we
would
write,
well
probably
dislike
this
discussion
right
here.
This
is
this
is
the
outcome
we
want
of
the
initial
like
design,
discussions
and
experiments.
We
should
be
able
to
get
samples
of
zone
SSDs
from
Western,
Digital,
I,
think
yeah,
hopefully
maybe
or
not,
so
we'll
start
that
waffle
prototype
right.
But
my
guess
is
that
whatever
workload
we
would
have
generated
for
a
zone,
SSD
will
be
optimal
for
a
regular
SSD.
Also,
the
only
differences
we
won't
have
to
bother
with
moving
with
a
where
Lavoie.
C
C
The
parallel
the
parable
of
that
is
that
actually
random,
writes
to
regular
ssese
are
incredibly
dangerous
in
terms
of
performance
variability
because
they
generate
write.
Amplification,
though,
rocks
DB
on
a
conventional,
less
estate
that
Western
Digital
had
a
booth
of
Buddha
web
was
doing
some
experiments.
He's
a
working
there's
been
working
with
the
sage
s
PhD,
whatever
he
was
saying
that
even
if
you
set
up
rocks
vbe2
use
it
like
this
rocks
and
he
just
does
the
quench
all
rights
right.
That's
all
it
does
yeah.
A
C
Still
get
a
right
amplification
of
Forex,
and
the
reason
for
that
is
that,
when
rocks
key
B
is
writing.
It
generally
sends
for
concurrent
streams
which
ideally
should
hit
for
concurrent
eraser
blocks,
but
in
practice,
because
of
the
FTL
the
way
the
FTL's
usually
work,
they
usually
hit
the
same
erasure
block,
because
her
physics
reasons
they
don't
like
leaving
erase
your
blocks
open
for
rights.
C
For
very
long,
though,
as
a
result
of
that,
even
though,
ideally
that
workload
shouldn't
have
generated
any
right
amplification
at
all,
you
have
four
times
as
much
as
they're
supposed
to
get
and
four
times
as
much
as
you're
supposed
to
get
means
a
bunch
of
things.
One
you're
gonna
have
to
copy
that
data
like
four
more
times,
which
means
the
media
only
lasts
about
a
quarter
is
long
and
a
bunch
of
I/o
gets
eaten
up
in
the
background.
Moving
the
data
around
when
you
do
erasers
to
free
up
space.
C
C
C
A

A

A

E

We
are
talking
about
the
error
handling
stuff,
in
particular
when
it
comes
to
a
chain
of
trust
of
your
error
handlers,
it's
not
specifically
to
retreats
up
forever
hunting
in
general,
you,
it's
very
likely
that
you
are,
you
will
encounter
a
function
accountable.
That
is
unaware
about
your
error
handler.
One
of
those
cases
is,
for
instance,
t-star,
do
for
each
method
in
order
to
not
not
impulse
and
add
extra
an
extra
o,
widely
available
error
rate
and
widely
available
to
users
to
programmers
methods
to
convert
between
a
error,
rated
future
and
applying
future.
D
C
D
Its
duplication,
I
will
turn
off.
I
would
love
to
avoid.
Actually,
we
could
do
with
very
small
fix
just
return
out
of
instead
future
in
this
particular
line
of
sister.
Maybe
we
could
convince
Abby
for
sub
small
patch
I.
Don't
I
don't
know
now
we
will
need
to
talk
doing
the
sister
stomach.
If
so,
we
will
be
able
to.
E
A
D
Current
implementation
of
step
do
for
each
doesn't
replicate.
Does
it's
not
a
copy
of
sister
d
forage
it
just
Kline
if
eyes,
a
related
future
call
calls
the
sister
do
for
each
and
turns
its
result
back
to
error.
I
teach
shooter
it's
process
a
copy,
but
it
can
be
also
made
in
a
way
that
that
there
is
no
copy
at
all
at
the
K
object
price
of
duplicating
the
implementation
of
assistant
for
each,
but.
A
D
Not
in
C++
seventeen
you
will,
you
will
actually
have
one
one
move.
There
will
be
no
copy.
Actually
one
move,
prom
Easter
from
Easter
you
church,
for
it
returned
from
Easter
do
for
each
that
is
being
called
from
safe,
do
for
each,
but
well
it's
a
move.
It's
you!
All
you
are
doing
is
basically
moving
the
internal
future
underscore
state
windows.
D
But
well
I
think
the
best
the
best
the
best
we
could
do
if
they
do
for
each
for
now
is
to
spend
it
it's
the
move.
What
we
already
have
a
staff
do
for
each
and
put
it
and
put
it
in
the
sister
namespace
and
that
that's
the
first
part
second
part
will
be
to
come
to
ask
Abby
just
to
embrace
those
Peaks
future
types
to
out.
In
that
way,
the
return
type
of
sister,
the
foliage,
will
be
determined
by
the
sister
food
rice
we
already
specialized
in
itself.
D
Those
utilities
usually
usually
and
usually
impulses
sister
future
from
raw
it,
which
means
that
well,
even
even
if
K,
even
if
you
will
to
go
with
some
outcome,
there
will
be
no
difference.
To
be
honest,
it's
it's
a
limitation
of
sister
okay,
if,
oh
by
the
way
I
made
our
local
testing
local
performance,
verification
of
the
aerator
versus
master
basically
looks.
There
is
no
a
huge
difference,
but
it's
on
my
my
local
machine
with
we
doing
a
random
reads.
Instead
of
sequential
edits
in
case
of.
