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

Advanced JS performance with V8 and Web Assembly (Chrome Dev Summit 2016)
觀看次數：421
v8
and
webassembly
-
so
what
is
v8
right
here
it's
to
speed
up
real-world
making
javascript
fast
that's
already
on
easier
to
write
performant
javascript
order
to
try
to
benchmark
v8
and
and
performance
characteristics
of
it
were
we
call
them
internally
just
top
25
and
the
alexa
ranking
but
they're
taylor
swift's
Web
twitter
page
as
the
twitter
example
so
so
there's
a
variety
vms
used
micro
benchmarks
to
measure
the
performance
of
code
now
micro
benchmarks
that's
a
micro
benchmark
it
just
tests
a
suites
things
like
octane
you
might
micro
benchmark
because
it
includes
real
code
octane
includes
a
gameboy
emulator
but
benchmarks
like
octane
are
static
so
we
have
an
updated
octane
since
we
websites
run
rate
tracers
so
as
I
swift's
twitter
page
does
not
have
a
ray
tracer
embedded
on
it
so
this
third
about
this
is
that
the
sophistication
of
probably
inversely
correlated
with
the
starting
out
and
optimizing
a
dirty
workload
like
a
micro
benchmark
workload
is
raises
drastically
and
benchmarks
sufficed
and
even
static
test
websites
well
we
instrumented
v8
so
that
we
could
that
a
lot
of
websites
run
compiled
javascript
or
at
least
a
lot
of
websites
javascript
and
there's
a
bunch
of
other
really
driven
our
optimization
in
the
25
websites
we
measure
by
5%
which
in
been
optimizing
page
loads
and
if
you
parser
not
necessarily
our
optimizing
workloads
when
we're
when
we're
working
and
the
speedometer
benchmark
even
websites
because
what
it's
doing
is
it's
correlated
to
super
domitor
and
so
as
of
speedometer
performance
by
15
to
25
that's
performance
but
there's
many
aspects
to
you
know
making
javascript
low-end
devices
so
these
are
memories
large
so
we
focused
on
reducing
the
particular
and
actually
reduced
chrome's
tweaking
the
heuristics
we
use
and
the
optimizing
compiler
there's
a
baseline
introducing
an
interpreter
to
v8
now
you
optimizing
compiler
or
a
jitang
compiler
to
make
optimizations
with
this
improvements
which
made
es6
generators
or
es2015
and
and
beyond
v8
supports
es6
that
haven't
been
actually
formalized
into
an
ex-minister
acro
script
standard
iterations
were
so
if
you've
been
programming
or
you
know
using
es
5
and
at
the
can
gac's
compatibility
table
a
the
browser
javascript
environment
is
just
half
of
the
javascript
environments
for
of
arrays
and
destructuring
and
all
well
as
built-ins
like
objectcreate
functionprototypebind
arrayprototype
eagerly
anticipated
features
of
all
of
async
and
await
our
primitives
which
readability
they
bring
debug
ability
and
of
like
pinterest
so
let's
let
me
make
loads
the
full
res
versions
so
i've
gone
and
i've
throttled
the
network
down
to
in
these
blurred
thumbnails
and
then
as
the
full
images
get
downloaded
i'm
async/await
i've
used
the
fetch
API
i'm
fetching
a
thumbnail
and
fetch
is
an
using
a
dot
then
i'm
decoding
the
boasts
for
what
i'm
doing
and
it's
not
converting
this
to
async
await
we
may
be
able
to
make
some
optimizations
so
how
that
javascript
is
so
heavily
relies
on
browser
doesn't
block
on
io
so
it's
very
model
of
programming
so
we
use
the
async
usually
the
async
keyword
just
goes
than
inserting
i'm
updating
my
thumbnail
before
my
full
resolutions
get
fetched
it's
hard
to
see
from
the
waterfall
but
thumbnail
so
that's
an
important
thing
supported
in
chrome
Canary
and
will
be
so
let's
wait
to
the
slides
feature
and
it
just
really
simplifies
browser
plugin
free
low-level
language
was
encumbered
by
particular
first
cross
browser
open
standards-based
so
lu
to
a
good
start
in
the
standardization
the
same
goals
but
by
using
a
backwards
compatible
javascript
syntax
so
web
it's
its
own
binary
format
and
it's
fast
and
webassembly
you're
dealing
with
numbers
and
in
32
s
and
62
s
float32
dealing
with
higher-level
javascript
powered
apps
if
you
thought
it
wasn't
and
other
things
which
traditionally
power
to
run
effectively
in
javascript
smoother
than
even
the
asma
jas
chrome
firefox
and
edge
so
this
demo
computationally
intensive
so
if
you're
encodes
and
decodes
jpegs
you
could
just
API
because
it's
exposed
to
javascript
is
by
calling
a
javascript
API
so
it's
interacts
with
javascript
in
html
so
is
and
we're
i'm
using
async
and
await
instantiation
of
the
class
it's
the
instantiated
more
than
once
and
you
level
javascript
thank
you
okay
so
we're
instances
in
javascript
have
a
simple
async
functions
are
return
promises
so
let's
take
two
numbers
and
let's
let's
even
if
you're
not
compiling
these
web
in
which
instead
of
downloading
an
npm
decoder
or
pdf
renderer
you
could
just
browser
preview
period
and
we've
computationally
intensive
code
so
thank
that
v8
is
continually
investing
not
but
in
unlocking
new
capabilities
and
improving
the
ergonomics
of
writing
web
