系統設計者的話：學英文根本不用背，你講中文，你有在背中文嗎？學英文也是一樣的道理，那是自然而然就會的東西，用背的方式最後肯定都是不行的。 更多...

最好的學習就是有英文的父母，不斷的跟你說話、耐心的教導你，時間長了，你也就慢慢就融入其中了。

但是我們沒有英文父母怎麼辦？看影片學英文就學的起來嗎？學不起來。

我們從小到大，也看過了不少英文電影，至少也看過1、200部也跑不掉，但是為什麼看了這麼多的英文電影，英文還是很爛呢？

主要的原因是我們沒有從基礎性的強化學習。舉個例子，西方的幼兒出生時，他至少聽了各種大人講英文至少聽了2年，才慢慢開始說英文、與大人互動。

而且都是一字一句慢慢的說、慢慢的教、漸進式的、慢慢的、越來越習慣、越來越聽的懂、越來越會說的過程。

那麼我們看的影片、電影過程中，都是大人成熟型的講話速度、方式、語調，我們怎麼可能跟的上？

一旦跟不上，思想中就會產生覺的好難哦、我不行種種念頭，那麼產生了這種潛在式的排斥心理作用，那麼你就更難學的會了。


所以我們必須打好基礎、深厚的基礎，萬丈高樓平地起，唯有打下深厚的基礎，後面你走的路才會越來越順。

程式界裏有句話，程式債欠的越多，最後就只能放棄。學英文也是一樣，英文單字債欠的越多，你就直接上來文法、句型、語調，最後也只能放棄。

基於上述的思維，我打造了這套系統，從最基礎的單字學習起，不斷的強化、加深你對這個單字的聽力，透過各式各樣的影片、各式各樣的人、各種不同的場景。

就只是為了訓練一個單字的聽力，無數的人跟你講同一個單字，講個20遍、50篇、100遍(且不重覆)，我就不信學不起來。


這套系統做出來後，我自己在使用的過程中，確實真的能聽出來他們講的這個單字，而且他們講的速度再快也能聽的出來。

能聽的出來，就知道他講的大概意思；能夠知道他講的大概意思，就能夠用幾個簡單的單字回應；能夠回應，也就能夠對話；當能夠對話，就能夠再修正文法、句型、語調。


我的目地就是希望自己至少能聽的懂人家在說什麼，用英文跟人家對話，大家共同努力、學習。若有其它想法或對這套系統設計的建議，也可以與我聯絡：ichich2013@gmail.com

V8 Performance from the Driver's Seat (Chrome Dev Summit 2015)

the
steering
say
I
mean
here's
just
a
different
performance
characteristics
this
creates
more
power
and
torque
but
characteristics
once
again
team
might
fundamentally
affect
the
aerodynamics
heuristics
that
they
tune
for
optimization
things
like
code
cashing
in
is
a
turbocharged
version
of
the
of
chrome
and
chromium
is
released
so
machinery
that's
being
evolved
goal
is
to
write
fast
javascript
that's
browsed
via
new
browsers
within
released
a
new
optimizing
compiler
we
second
so
let's
start
with
turbofan
optimizing
compiler
now
v8
as
an
engine
I
mentioned
compiles
dynamic
javascript
optimizations
so
why
do
we
write
a
new
optimizing
compiler
well
we
wanted
to
unparalleled
and
allows
us
to
to
support
atmos
script
2015
so
it's
true
supported
them
syntactical
e
in
our
older
compiler
we
couldn't
use
all
of
the
optimization
techniques
that
let's
the
support
was
spotty
but
turbofan
will
you're
using
in
javascript
if
you
use
in
the
browser
more
intelligently
now
all
of
these
optimizations
make
the
browser
feel
so
much
lighter
so
what's
in
chrome
released
a
scheduling
api
the
browser
that
is
when
clicks
are
explains
why
jank
happens
in
the
browser
animation
feels
kind
of
jerky
and
stuttery
well
for
smooth
animation
you
of
this
diagram
has
markers
for
frames
between
those
frames
the
browser's
doing
work
it's
running
javascript
execution
it's
it's
often
variable
some
frames
is
increasing
soviet
has
to
have
a
miss
the
frame
this
is
a
janky
disrupted
animation
with
the
scheduler
API
though
happening
from
v8
so
we
can
proactively
resulting
in
smoother
animation
here
is
browser
on
the
right
it's
even
smoother
more
intelligently
win
to
schedule
150
200
megabytes
but
the
crazy
part
or
heat
boom
it's
down
to
80
megabytes
memory
that
the
older
versions
of
chrome
now
working
on
implementing
es2015
and
determines
what
the
javascript
language
proxies
arrow
functions
ja
v8
has
classes
on
newer
syntax
and
semantics
for
better
object-oriented
javascript
programming
we've
shipped
spread
and
rest
operators
structuring
assignments
but
we've
got
a
committed
to
delivering
es2015
in
the
we're
doing
this
in
turbofan
it's
not
we're
really
committed
to
optimizing
designing
v8
is
all
about
trade-offs
as
computationally
expensive
cpu
operations
are
browsing
from
what
we
call
spelt
devices
or
these
android
phones
or
reduced
memory
profiles
so
while
you
may
512
megabytes
of
memory
this
makes
it
compilations
for
javascript
so
ignition
native
but
it
is
drastically
reduced
from
your
javascript
ast
that's
three
to
the
bat
in
a
browser
frameworks
v8's
motto
is
to
make
all
the
of
you
use
frameworks
when
you're
when
angular
ember
polymer
all
of
these
and
it's
things
what
we
call
polymorphic
so
v8
historically
has
made
these
these
modern
frameworks
are
using
and
optimize
and
we've
been
working
internally
on
deterministically
for
our
testing
so
frameworks
so
this
is
what
v8's
been
algorithms
and
you
know
optimize
the
the
times
when
you're
optimizing
for
more
importantly
over
time
its
to
the
browser
and
adapt
to
new
versions
ayrton
senna
doesn't
have
a
mechanical
fundamental
enough
that
they're
they're
monkey
and
firefox
javascriptcore
and
creating
structs
likessee
likes
trucks
javascript
you
can
dynamically
set
obviously
because
it's
valid
javascript
properties
in
object
constructors
don't
dynamically
add
or
remove
them
here's
an
so
it
says
AHA
we're
going
to
optimize
twice
it's
gonna
be
optimized
for
talking
about
before
javascript
doesn't
highly
optimized
machine
code
versions
and
consistently
use
them
without
d
optimizing
now
this
is
called
mont
amorphous
and
that's
just
a
fancy
word
other
heuristics
that
v8
and
jsc
and
can
pass
in
certain
flags
and
introspect
what's
going
on
into
the
hood
there's
you
can
see
those
same
D
optimizations
actually
don't
have
it
installed
and
if
you're
not
a
chromium
developer
you
probably
don't
have
it
installed
either
but
i
do
have
knowed
installed
and
node
included
it's
46
that's
the
same
as
chrome
version
46
that's
what
i'm
have
know'd
installed
i
can
pass
in
this
javascript
file
and
it
logs
out
when
those
those
horrible
d
optimizations
that's
the
one
that's
that
we
want
to
by
squinting
at
it
kind
of
how
optimized
because
there's
no
more
d
optimization
improvements
it's
the
v8
blogspot
at
v8
constantly
changing
we're
constantly
communicating
more
so
if
you've
got
code
googlegroupscom
talk
with
us
show
us
optimizations
when
you
shouldn't
be
show
contribute
benchmarks
of
real-world
apps
real-world
apps
so
send
us
stuff
that
optimize
it
and
finally
to
anti-patterns
about
how
v8
doesn't
optimize
try-catch
about
to
ship
optimized
versions
a
try-catch
so
these
characteristics
on
tooling
to
figure
out
what's
betaine
and
lastly
don't
use
micro
benchmarks
to
make
design
decisions
when
I
talk
about
benchmarking
and
so
don't
use
micro
benchmarks
and
lastly
at
googlegroupscom
look
forward
to
