What is the Difference Between Shadowsocks and a VPN?
Because of China’s Great Firewall, Chinese people must
circumvent restrictions to post on Facebook, use Google services, stream
videos on YouTube, and so on.
VPN is a popular tool in
China for accessing blocked content and services. In 2012, a
Chinese programmer designed Shadowsocks to bypass Internet censorship in
China and shared it on GitHub. Shadowsocks, or SS for short, became
popular among Chinese Internet users.
Since Shadowsocks and a VPN are easily confused, I would like to give an introduction from four parts.
What is a VPN?
On the one hand, both VPNs and Shadowsocks
unblock websites for
you. On the other hand, a private network will be built by the VPN to
transfer data at the network level. A VPN, known as a
virtual private network,
encrypts your communications online. It is widely used
in corporate and university networks. When you connect to a VPN, you
are actually connecting to a private network. Your Internet access is
via this private network. Whether the communication between you and the
VPN is encrypted or not depends on the VPN protocol used.
What is SS / SSR?
SS (Shadowsocks): It was created by clowwindy to bypass the GFW in
2012. The developer then found it useful to unlock websites because
traffic goes through it is difficult to detect while it ensures a fast
Internet connection. That’s why clowwindy shared it with others on
GitHub. However, in 2015, the creator was under pressure from the
Chinese government. In consequence, clowwindy removed code on Github
and pledged not to participate in any maintenance or update of
Shadowsocks.
SSR (ShadowsocksR): After what happened to Shadowsocks in 2015,
another developer, breakwa11, claimed that SS could easily be recognized
by GFW. Thus, breakwa11 created ShadowsocksR based on Shadowsocks that
support traffic obfuscation.
Later, breakwa11 was also forced to remove all code on GitHub and
discontinue the development of Shadowsocks. Relevant groups were also
deleted. Since many people forked SSR, new versions based on SSR
continued to be released. SSRR is a well-known example.
How does Shadowsocks work?
SS and SSR work in the same way. They are SOCKS5-based
proxies. SOCKS proxies transmit data packets no matter
what transfer protocol is used. SOCKS proxies are much faster than
other application-level proxies. The SOCKS5 proxy sends your data
request via a connection between you and the proxy server, which
forwards your request to the destination. During this process, your data
request will not be routed through a dedicated tunnel. There is
no additional processing when the data packet is sent to the proxy
server. If you want to check your Gmail, you can achieve this
by sending a request to a Hong Kong server over a SOCKS5
connection. Afterward, your Hong Kong server receiving your request will
visit Google and return the result of that request to you.
Shadowsocks offers three modes. Direct connection mode does
not redirect your traffic through the proxy server. The settings preset
for some apps will continue to work in this mode. When PAC mode is
enabled, only traffic to GFW-blocked websites is routed through the
proxy server. In global mode, all traffic is redirected through the
proxy server. Users can choose a mode that suits their needs.
Pros and cons of a VPN and SS
Shadowsocks is born for circumventing geo-blocks. It is based
on the SOCKS5 proxy but is different from a normal proxy. Because it has
some features specifically designed to bypass the GFW.
There is no private tunnel between the client and the server. The
client communicates with the server you want to access through the proxy
server. All data should be transferred via the proxy server.
VPN is the abbreviation for
virtual private network. Connecting
to a VPN means connecting to a private network. All Internet traffic
should reach the destination via this private network. At the same time,
the IP address of the user also becomes the IP address assigned by the
VPN.
Comparison of a VPN and Shadowsocks:
Shadowsocks is open-source and can be constantly evolving.
The SOCKS5 does not require any handshake except for a TCP
connection. Each request forwards only one connection and does
not require a connection all the time. Thus, it is relatively fast
and energy-efficient for mobile devices.
Shadowsocks can disguise the traffic as normal HTTP / SOCKS
traffic, making it hard to detect. While VPNs can be easily detected
and blocked.
Shadowsocks let users decide what traffic is routed through the
proxy server by selecting different modes. However, all traffic should
be routed through the VPN.
Shadowsocks can only redirect traffic. While a VPN encrypts traffic and ensures data security.
A user can mask the IP address with that of the VPN server. So the user can switch location.
Conclusion:
SS / SSR would be better for those who just want to bypass Internet censorship. It cost you less money to get SS / SSR. While a
VPN
is relatively more expensive. Although there are some free VPNs, we do
not recommend users to select them. If you care more about data
security, you should opt for a reputable
VPN

Samsung Galaxy 10 and Note 10 series have a serious security issue
with the ultrasonic fingerprint scanner, which was revealed recently. A
user who registered a fingerprint after the phone was covered with a
screen protector can unlock this phone with other fingers that didn’t
register. Samsung officially said this security flaw was the
malfunctioning fingerprint recognition and a patch would be issued as
soon as possible to fix it. Qwer432
Samsung’s malfunctioning fingerprint recognition
This was first discovered by a British couple on October 13. The wife
applied a screen protector to her Samsung Galaxy S10 and scanned her
right thumbprint. Then, she found that her left thumb, which hasn’t
registered, could unlock her S10. So did her husband’s thumbs. However,
the fingerprint is used to unlock a phone as well as to pay, which will
raise a lot of concerns. Your smartphone security is essential to your
personal information and financial security. Because various payment
services, including Samsung Pay, allow users to verify a payment with
their fingerprints. This means that anyone can access your mobile
banking apps on Samsung smartphones, which poses a big threat to the
financial security of users.
As a result, many relevant service providers took action to avoid being
affected by this security flaw. For example, the Bank of China announced
on Oct. 19 that it would disable the fingerprint login function for its
mobile banking app on Samsung. Natwest and Nationwide Building
Society, two British Banks, even removed their mobile banking apps
directly from Samsung Galaxy S10. Another Israeli netizen said they were
not allowed to log in to the mobile banking apps with a fingerprint.
How did Samsung respond to this issue?
Samsung Electronics immediately recognized the seriousness of this
case and issued an official statement the day after the discovery,
admitting that there was a malfunction with the fingerprint recognition
program on Samsung Galaxy S10 and Note 10 series. It claimed that it was
a malfunction that can be fixed with a patch. Relevant fixes will be
released as soon as possible. In addition, users could adopt a temporary
solution before the patch was released by keeping away from a screen
cover and deleting fingerprints scanned with a screen cover.
On October 24, Samsung Electronics announced that it had released a
software update to fix the fingerprint identification vulnerability of
Samsung Galaxy S10 and Galaxy Note 10 series of mobile phones. Samsung
also apologized to users on “Samsung Members” and reminded them to
update their biometric authentication to the latest version of the
software as soon as possible. Samsung said it unlocks the device when
the ultrasonic fingerprint sensor treats the 3D pattern on a specific
silicone screen protector as the user’s fingerprint. Samsung advised
users to remove the protective film, remove all previous fingerprints
and re-register.
This ultrasonic fingerprint scanner used to be the pride of Qualcomm. It
can not only identify the user’s fingerprint texture through water,
grease and other things but also detect human blood, which means
that fake phones and artificial skin are impossible to fool the
ultrasonic fingerprint scanner. Samsung touted it at the launch as a
revolution in biometric authentication.
Why was there a security issue with Samsung’s ultrasonic fingerprint scanner?
Some netizens think it is because the British user registered
her fingerprint when using a fully covered silicone case (that is to
say, the phone also has a transparent silicone case on the
screen). Actually, it is the texture of the silicone case that is
scanned, but not her fingerprint. Samsung used Qualcomm’s third
generation of the 3D ultrasonic fingerprint sensor, which identifies
fingerprints via ultrasonic. So, the phone may scan the texture of the
silicone case when the user registers a fingerprint over the silicone
cover. They believe that the ultrasonic fingerprint scanner from Samsung
and Qualcomm is still the most advanced technology in the industry.
Some netizens also have concerns about the security of this technology.
They hold the view that it is the ultrasonic fingerprint scanner itself
not safe enough.
Later, a netizen said that the Samsung phone could be unlocked with the
unregistered fingerprint only over a TPU film even if the fingerprint
was scanned without a screen cover. If so, it would be more complex.
What do you think? Except for such security issues, your privacy is also
vulnerable to hackers while you surfing the Internet. You’d better
install a
VPN on your phone to stay safe and private online.

One of the UK's leading public schools, Wellington College, will open a
new international school in Hangzhou, capital of east China's Zhejiang
Province, in September, the school announced Thursday.
hangzhou international school
Wellington College International Hangzhou is located in Xiaoshan
District of Hangzhou and aims to offer international education for
children of expatriate families from ages 5 to 18. In the first phase of
opening in 2018, the College will operate for students in Year 1 to
Year 6, or ages 5 to 11, and then grow each year to offer a pathway to
A-Levels or the IB Diploma.
This will be Wellington College China's third international school
after Tianjin and Shanghai and the 13th new member of the Wellington
College family worldwide.
According to Paul Rogers, Founding Executive Master of Wellington
College Hangzhou, Wellington College has chosen Hangzhou as the location
for its third international school in China because it sees a demand
for high-quality international education following Hangzhou's successful
G20 Summit in 2016.
"Hangzhou's reputation as a hub for innovation and creativity has
attracted high-end foreign talent in fields such as technology and
e-commerce. Many have moved to the city with families, and this has
triggered high demand for international education institutions," said
Rogers.
Statistics show that Hangzhou had more than 25,000 foreign students
studying in higher education institutions in the city and 15,000 skilled
foreign workers as of the end of February. The city rolled out new
measures to attract foreign talent in late February. It also plans to
introduce 10 international schools by 2022.
Rogers also believes that the new school is part of the increasing educational cooperation between China and the UK.
According to the UK Department for International Trade, there will
be more than 20 British school brands with over 50 campuses in China by
the end of 2020.
"Wellington College wants to combine the best of Chinese and British
education and culture and provide an education that will produce truly
global citizens," said Rogers.
Tianjin Yinghua Cambridge International School (TYCIS) is part of the
larger Yinghua International School situated in the Wuqing District of
the historic Chinese city of Tianjin. It is now entering its 6th Year of
operation offering students in Years 10 to 13 the CAIE curriculum of
IGCSE, AS and A Levels. Thus far the students have attained amazing
results and the graduates have gone on to study in the top universities
in the UK, USA, Canada, Hong Kong and the like.
international school in Tianjin
The school is academically selective and is oversubscribed.
Currently with 320 students it is expanding as planned to its capacity
of approx 500 students. The students are a delight to work with being
able, self motivate and well mannered. Each year a significant
percentage of the graduating class are interviewed at Oxford or
Cambridge and gain places there, with all going on to universities of
world renown.
Wuqing is a pleasant, clean and modern environment conveniently
situated on the outskirts of Tianjin. The cost of living is low, yet
the quality of life is high in this district. It enjoys easy access to
both Tianjin centre and Beijing using the high speed rail system.
Staff turnover is exceptionally low and staff remuneration and
benefits are the equal, or better of most international schools in the
region.Staff are treated well and are able to enjoy a good standard of
living with significant opportunities for saving. The above combine to
make TYCIS a great employment opportunity for you. We welcome visitors
to the school by appointment.
Linda Here. So what do you picture in your mind’s eye when I say “an
international school in China?” Before today I wouldn’t have had a clear
expectation or picture in my head. We arrived at TIS (Tianjin
International School) to perform a concert for the assembly of students
at the end of their school day. But not before we were given a tour of
the school’s facilities. To say the least the classrooms and resources
of the school were astonishing. TIS includes elementary, middle, and
high school, each with their own corresponding libraries. Their Arts
programs showed flourishing into all kinds of learning. At TIS it was
very obvious how highly the school values representation. There is a
display of many nations flags in the foyer of the school, every flag
that is displayed represents the presents of students from that nation
attending TIS. Some of our education majors on the tour described TIS as
their dream job.
Tianjin international school
A good friends of mine, Kirby Peters, is a 3rd year education major on the China tour.
She described TIS as “…having an obvious focus on incorporating and
understanding many different cultural perspectives. They make a
conscious effort to strive for excellence in both their students and as
an institution. Classrooms are set up to promote cooperative learning
and teamwork and are decorated in such a way where student work is
highlighted and fits into the overall theme and design of the
classroom….One of the most telling parts of the quality of a school is
found through watching the teachers. Everyone we met was friendly, warm
and looked like they were truly enjoying their job. This comes from
strong leadership, support, a team mentality, and appreciation for the
other members of your team. All of which seemed to be present at TIS”
The Chamber Choir considered it a great honor an privilege to be
able to perform for such a high quality institution and student body as
TIS.
Learning is a lifelong journey – even for teachers! YCIS Shanghai, Puxi
recently opened their doors to educators from around Asia for an
inspiring learning experience. The 2019 ACAMIS Chinese Conference shared
best practices and information on the latest advancements in teaching
Chinese, with the theme “Learning Chinese Should be Fun: Methods to
Enhance Learning.”
International school Shanghai
Students from Britannica International School recently visited a
sister Orbital Education School and learnt to sail in Mallorca, Spain.
Students awoke to blue skies and ventured out onto the water. They also
experienced amazing cultural activities and can’t wait to return next
year.
Students, teachers, parents and school community members at The
British School of Shanghai, Puxi (BISS Puxi) and Nord Anglia
International School, Pudong (NAIS Pudong) celebrated thanks to students
achieving exceptional results in the International Baccalaureate
Diploma Programme for the 2018/19 academic school year.
The Global average for IB schools is 30 points (45 being the
highest), so with an average score of 36 points – and one third of
students achieving 40 points or above – the gap between those attending a
Nord Anglia school in Shanghai and the global average widens. These
results are testament to Nord Anglia’s Be Ambitious philosophy, ensuring
that every child excels.Congratulations to Dulwich College Shanghai
Pudong Year 5 students, who performed marvelously at their band program
concert! A delightful audience applauded as the students showcased their
musical knowledge studied throughout the year. Each section of the band
was showcased in a variety of pieces during the concert; ‘Power Rock,’
‘Supercalifragilisticexpialidocious’ and ‘Do-Re-Mi’ were just some of
the melodies the proud audience heard. Listeners showed great
appreciation for the young learners’ accomplishments throughout the
year. This was a wonderful concert of joy and commitment from our
students. Well done Year 5 DCSPD students on your performance!
The perfect ‘showcase day’ end to the academic year for Harrow,
Prize Givings are a traditional institution within the very best British
schools. It is the time when the many achievements of the pupils over
the year are celebrated, the Upper Sixth leaving students and departing
staff can be given a rapturous send-off, and prizes can be awarded to
those pupils who have impressed most in terms of their academic
achievement, their levels of progress, their high industry, their
commitment to the wider life of the school, their leadership and other
areas of school life. In essence, it is a celebration of what it means
to be a ‘Harrovian’.
The Institute of Education Sciences (IES) and the National Science
Foundation (NSF) have released a report, “Common Guidelines for
Education Research and Development.” The report provides important
guidance to program officers in both of the agencies, prospective
grantees, and peer reviewers.
Educational research and development
Overall, the report is intended to create a shared framework for six
types of research that the agencies fund. It describes the purpose of
each type of research, the theoretical and empirical justifications for
conducting the research, the expectations for the design and products of
the research, and the expectations for review of the products.
As noted in the Preface, the report generally adheres to the guiding
principles for research as set forth in the National Research Council
2002 report Scientific Research in Education. The report also cites
AERA's Standards for Reporting on Empirical Social Science Research in
AERA Publications. Executive Director Felice Levine applauded the
document on its release as “another valuable set of guidance in the
cycle of knowledge production.” She urged researchers and students to
consider these Guidelines well before they consider the submission of a
proposal for federal funding.
A draft of this report was presented at a featured symposium that
included small discussion groups at the 2013 AERA Annual Meeting.
Further follow-up is anticipated at the 2014 Annual Meeting.
Tulare County deputies have repeatedly advised the public that water
activities and drinking alcohol don't mix. On Sunday afternoon, one man
learned the hard way how serious deputies are about water safety.
Children swimming in Shanghai
Deputies with the sheriff's Boating Safety Enforcement Unit were
conducting an unrelated vessel stop near the Kaweah Recreational area on
Lake Kaweah.During the stop, deputies saw a man and a child, without
life jackets, swimming in deep water more than a 100 feet from shore.
The man, later identified as Tommy Hawkins, swam toward the patrol
boat with an 11-year-old child, leaving four other children unattended,
deputies said. Deputies say Hawkins was "extremely" intoxicated and
"belligerent."
Because of the Hawkins' "level of intoxication," deputies said they
felt he was unable to care for his safety or the safety of the children.
Hawkins was arrested on suspicion of child endangerment and booked
into Tulare County Pretrial Facility.The children were turned over to
Tulare County ChildWelfare Services, according to deputies. Deputies
sent out the following warning to visitors:
"Alcohol interferes with balance, coordination and judgment,"
deputies said. "These effects are heightened by sun exposure and heat.
Wear life jackets and watch your children around water. Remember life
jackets save lives. Alcohol and boating don’t mix."
This case is currently under investigation by the Tulare County
Boating Safety Enforcement Unit.Detectives believe they gathered enough
evidence to hold the woman accountable for the incident. She is
suspected of being under the influence when she took her child into the
river, a popular summer hot spot that cuts through Visalia.
The European Central Bank (ECB) announced a massive new bond-buying
program Thursday in a bid to stimulate the ailing euro zone economy.
A Level Programme
The central bank’s quantitative easing (QE) program will entail 20
billion euros ($21.9 billion) per month of net asset purchases for as
long as it deems necessary.The ECB also cut its main deposit rate by 10
basis points to -0.5%, a record low but in line with market
expectations.
It now expects interest rates to remain at their present or lower
levels until it has seen its inflation outlook “robustly converge to a
level sufficiently close to but below 2% within its projection horizon,
and such convergence has been persistent.”
In a press conference following the decision, ECB President Mario
Draghi urged governments to take fiscal measures to supplement the
central bank’s monetary stimulus and reinvigorate the euro zone
economy.“In view of the weakening economic outlook and the continued
prominence of downside risk, governments with fiscal space should act in
an effective and timely manner,” Draghi said.
“In countries where public debt is high, governments need to pursue
prudent policies that will create the conditions for automatic
stabilizers to operate freely. All countries should reinforce their
efforts to achieve a more growth-friendly composition of public
finances,” he added.Additionally, the ECB changed its TLTRO (targeted
long-term refinancing operations) rate to provide more favorable bank
lending conditions and match that of its refinancing rate, erasing a
previous 10 basis point spread.
A new system will see borrowers receive preferential rates if their
eligible net lending exceeds a benchmark, providing an incentive for
banks to use that money.
In line with market expectations, the ECB also introduced a two-tier
rate system, a measure encouraged by the heads of various major
European banks during the latest earnings season. The move is intended
to alleviate some of the pressure of negative interest rates on the
balance sheets of European banks, which have seen profits squeezed by
the persistent low rate environment.Draghi added in his press
conference: “In order to support the bank-based transmission of monetary
policy, the Governing Council decided to introduce a two-tier system
for reserve remuneration, in which part of banks’ holdings of excess
liquidity will be exempt from the negative deposit facility rate.”
The American Quarter Horse Foundation hosted the opening night of its
12th annual America’s Horse in Art Show and Sale Saturday evening at the
American Quarter Horse Hall of Fame and Museum.To get more
horse paintings, you can visit shine news official website.
Throughout the evening, attendees look at the art, ranging from
watercolor paintings to bronze pieces, chosen by a juried panel each
year from artists around the world. Attendees then bid on the pieces so
they could take them home when the exhibition ends in October, raising
money for the foundation.
Craig Huffhines, the chief executive officer for the American
Quarter Horse Association, said this is a great event for the community
to come together and celebrate the foundation as well as the art.
“This is one time a year where the community gathers, the who’s who
of Amarillo comes in to celebrate America’s Horse in Art, which is a
celebration of our great horse and our heritage,” he said.Museum curator
Crystal Phares said 43 artists were chosen to participate in this
year’s show. Artists, year after year, are inspired by the horse as an
animal.
“The horse itself is a living work of art,” Phares said. “It’s hard
to not be inspired by a horse. I think it really translates because
people are passionate about the horse. They are a companion. They are
our friends.”Jack Sorenson, an artist who has participated in each of
the 12 shows, said it is a big deal for Amarillo to host an art show
like this. As the event each year progresses, Sorenson thinks the art
gets better and better.
Being a full-time artist for 45 years, Sorenson said he sees a huge
difference from how he approaches his art now than he did in the past.
But his work has one consistent theme.“Most of my paintings have
storylines,” Sorenson said. “I don’t know where the ideas come from. I
grew up in this lifestyle, so I paint a lot of paintings of what
happened to me when I was a kid growing up. God will give me an idea
right when I’m about to fall asleep.”
Sorenson said he hopes this show becomes more nationally renowned in
the future, but it touches him that people come out to the annual show
and purchase art.“It means a lot to me when someone goes out of their
way to come to something like this and then they leave with one your
paintings,” he said.
Phares said this event gives people the unique opportunity to
appreciate horses without having to purchase one.“The American Quarter
Horse is a beautiful animal,” Phares said. “What better way to share
that with people who maybe don’t want to have a horse, but they are in
love with the horse?”
