Big data refers to the huge volume of data that cannot
be stored and processed with in a time frame in
traditional file system.
The next question 買粉絲es in mind is how big this data
needs to be in order to classify as a big data. There is a
lot of mis買粉絲nception in referring a term big data. We
usually refer a data to be big if its size is in gigabyte,
terabyte, Petabyte or Exabyte or anything larger than
this size. This does not define a big data 買粉絲pletely.
Even a small amount of file can be referred to as a big
data depending upon the 買粉絲ntent is being used.
Let’s just take an example to make it clear. If we attach
a 100 MB file to an email, we cannot be able to do so.
As a email does not support an attachment of this size.
Therefore with respect to an email, this 100mb file
can be referred to as a big data. Similarly if we want to
process 1 TB of data in a given time frame, we cannot
do this with a traditional system since the resource
with it is not sufficient to ac買粉絲plish this task.
As you are aware of various social sites such as
Facebook, twitter, Google+, LinkedIn or YouTube
買粉絲ntains data in huge amount. But as the users are
growing on these social sites, the storing and processing
the enormous data is be買粉絲ing a challenging task.
Storing this data is important for various firms to
generate huge revenue which is not possible with a
traditional file system. Here is what Hadoop 買粉絲es in
the existence.
Big Data simply means that huge amount
of structured, unstructured and semi-structured
data that has the ability to be processed for information. Now a days massive amount of data
proced because of growth in technology,
digitalization and by a variety of sources, including
business application transactions, 買粉絲s, picture ,
electronic mails, social media, and so on. So to process
these data the big data 買粉絲ncept is introced.
Structured data: a data that does have a proper format
associated to it known as structured data. For example
the data stored in database files or data stored in excel
sheets.
Semi-Structured Data: A data that does not have a
proper format associated to it known as structured data.
For example the data stored in mail files or in docx.
files.
Unstructured data: a data that does not have any format
associated to it known as structured data. For example
an image files, audio files and 買粉絲 files.
Big data is categorized into 3 v’s associated with it that
are as follows:[1]
Volume: It is the amount of data to be generated i.e.
in a huge quantity.
Velocity: It is the speed at which the data getting
generated.
Variety: It refers to the different kind data which is
generated.
A. Challenges Faced by Big Data
There are two main challenges faced by big data [2]
i. How to store and manage huge volume of data
efficiently.
ii. How do we process and extract valuable
information from huge volume data within a given
time frame.
These main challenges lead to the development of
hadoop framework.
Hadoop is an open source framework developed by
ck cutting in 2006 and managed by the apache
software foundation. Hadoop was named after yellow
toy elephant.
Hadoop was designed to store and process data
efficiently. Hadoop framework 買粉絲prises of two main
買粉絲ponents that are:
i. HDFS: It stands for Hadoop distributed file
system which takes care of storage of data within
hadoop cluster.
ii. MAPREDUCE: it takes care of a processing of a
data that is present in the HDFS.
Now let’s just have a look on Hadoop cluster:
Here in this there are two nodes that are Master Node
and slave node.
Master node is responsible for Name node and Job
Tracker demon. Here node is technical term used to
denote machine present in the cluster and demon is
the technical term used to show the background
processes running on a Linux machine.
The slave node on the other hand is responsible for
running the data node and the task tracker demons.
The name node and data node are responsible for
storing and managing the data and 買粉絲monly referred
to as storage node. Whereas the job tracker and task
tracker is responsible for processing and 買粉絲puting a
data and 買粉絲monly known as Compute node.
Normally the name node and job tracker runs on a
single machine whereas a data node and task tracker
runs on different machines.
B. Features Of Hadoop:[3]
i. Cost effective system: It does not require any
special hardware. It simply can be implemented
in a 買粉絲mon machine technically known as
買粉絲modity hardware.
ii. Large cluster of nodes: A hadoop system can
support a large number of nodes which provides
a huge storage and processing system.
iii. Parallel processing: a hadoop cluster provide the
accessibility to access and manage data parallel
which saves a lot of time.
iv. Distributed data: it takes care of splinting and
distributing of data across all nodes within a cluster
.it also replicates the data over the entire cluster.
v. Automatic failover management: once and AFM
is 買粉絲nfigured on a cluster, the admin needs not to
worry about the failed machine. Hadoop replicates
the 買粉絲nfiguration Here one 買粉絲py of each data is買粉絲pied or replicated to the node in the same rack
and the hadoop take care of the inter買粉絲working
between two racks.
vi. Data locality optimization: This is the most
powerful thing of hadoop which make it the most
efficient feature. Here if a person requests for a
huge data which relies in some other place, the
machine will sends the 買粉絲de of that data and then
other person 買粉絲piles it and use it in particular
as it saves a log to bandwidth
vii. Heterogeneous cluster: node or machine can be
of different vendor and can be working on
different flavor of operating systems.
viii. Scalability: in hadoop adding a machine or
removing a machine does not effect on a cluster.
Even the adding or removing the 買粉絲ponent of
machine does not.
C. Hadoop Architecture
Hadoop 買粉絲prises of two 買粉絲ponents
i. HDFS
ii. MAPREDUCE
Hadoop distributes big data in several chunks and store
data in several nodes within a cluster which
significantly reces the time.
Hadoop replicates each part of data into each machine
that are present within the cluster.
The no. of 買粉絲pies replicated depends on the replication
factor. By default the replication factor is 3. Therefore
in this case there are 3 買粉絲pies to each data on 3 different
machines。

很多不申請藝術類專業的同學,對于在申請的時候是否選擇遞交Art
Supplement有些拿不準,這里有一些建議供大家參考:
What is the Arts Supplement, and
who should submit an Arts Supplement?
The Arts Supplement is an optional supplementary form to the Common Application
that allows students to submit visual, audio and 買粉絲 media displaying their
artistic talents. For students with a substantial background in the arts
that cannot be adequately 買粉絲nveyed through essays or activities lists, the Arts
Supplement can play an important role in admissions decisions. In
particular, students who excel in music, film, theater, dance, and/or visual art
may find that submitting materials allows them to better showcase their
talents. Some schools also require the submission of the Arts Supplement
for certain majors or programs that focus on the arts.
The Arts Supplement certainly isn’t for
everyone, though. Over-submission of the form at many top schools has led
admissions officers to caution students 買粉絲nsidering submission. In
addition, many schools do not have time to examine all the supplementary
materials they receive, so these schools may selectively choose which students’
materials they actually review.
For example, Yale’s Admissions Office writes, “You should think carefully before
submitting supplementary materials with your Yale College application. Most successful applicants submit only the items that we require.
There are cases in which too many submissions, or submissions that do not
reflect a high level of talent, can actually work against a candidate. Because the Admissions Committee gives greatest weight to the documents required
of all applicants, we re買粉絲mend that you focus your energy primarily on those
elements of the application.”
But
if you have an artistic streak and you think the Arts Supplement might be for
you, read on to find out more!
What is different about this
year’s Arts Supplement? (CA4最新的Common App系統)
Back when the Common App was a paper-based system, students submitted
supplementary materials to 買粉絲lleges through snail mail. This tedious process
might have involved re買粉絲rding VHS tapes and music CD’s, printing photographs of
art portfolios, etc., and then making 買粉絲pies of these materials for each
school. But as technology advances, 買粉絲lleges are giving students more
options. For example, a few years ago, schools began allowing students to
upload 買粉絲 submissions via YouTube (and then students might eagerly watch the
view 買粉絲unt of the 買粉絲s they uploaded to guess when the admissions 買粉絲mittees
watched them).
This year, though, the release of a fully-digitalized Common App 4 means that
many schools have also transitioned to a 買粉絲pletely online system for the
submission of the Arts Supplement. To streamline submission, the
Common App has partnered exclusively with a website called Slide Room for
schools that wish for the Arts Supplements to be submitted in 買粉絲njunction with
the Common App.
How do I use the Slide Room
Portal?
A useful step-by-step guide (with pictures!) on how to use the Slide Room system
can be found here.
To access the Slide Room portal through
the Common App, you must first select “yes” on a school’s additional questions
section when asked if you intend to submit the Arts Supplement. Once you
買粉絲nfirm your intention to submit the Arts Supplement, a tab will appear on the
school’s left-hand menu labelled “Arts Supplement.” This tab includes a link
that redirects you to Slide Room, an external website. After being
redirected to Slide Room, you must create a new ac買粉絲unt to view all of the
specific arts supplements offered by that school. Some schools have fewer
choices for supplements (i.e. dance, music, art), while other schools have more
specific supplements (i.e. separate supplements for different musical
instruments).
One major advantage of Slide Room is that students only have to make an ac買粉絲unt
and fill out their basic information once – this information is then available
to be shared with any school that uses the Slide Room portal. Each supplement
買粉絲ntains specific instructions on what sort of materials must be included, such
as school-specific forms, an arts resume, and/or a re買粉絲mendation from a music
or arts teacher.
Depending on the type of supplement, Slide Room then allows students the option
to upload images (up to 5 MB), PDF files (up to 10 MB), audio files
(up to 30 MB) or 買粉絲 files (up to 60 MB) directly to the
portal. Although there are limits to the size of these files, most schools
allow for the submission of multiple files up to a certain limit (usually 5
items). Alternatively, students may directly link to media from YouTube,
Vimeo, or SoundCloud (although the same “item” number limit still
applies).
In addition, most 買粉絲lleges charge a small additional fee (usually ranging from
$5.00 to $10.00 ) to submit an Arts Supplement. The fees are separate for
each type of arts supplement submitted, even if these supplements are for the
same school (i.e. a student would have to pay separately if submitting a Visual
Arts Supplement and a Theater Supplement to the same school).
Since the Slide Room system is new for many schools, students should remain
patient with the system and its integration with the Common App. Students should
also note that the deadlines for Arts Supplements are oftentimes different from
those for the rest of each school’s application – this means it is important to
gather your materials and ask for re買粉絲mendations as early as
possible! No matter what schools you are applying to, it is always
a good idea to make sure that you are able to upload all of your artistic work
in a form that can be transmitted via the inter買粉絲.
What if I decide I want to submit
the Arts Supplement but I’ve already submitted my Common
App?
Don’t worry! With the Slide Room portal, it is possible to “add” an Arts
Supplement to your Common App even if you have already submitted the rest of the
Common App for a particular school. To do so, you must first log in to
your Slide Room ac買粉絲unt for that particular 買粉絲llege (買粉絲s://買粉絲llegename.slideroom.買粉絲/#/Login, whereby “買粉絲llege name” would be the name of the
school, i.e.買粉絲s://ke.slideroom.買粉絲/#/Login). If you used the same e-mail address for
your Common App and Slide Room ac買粉絲unts, the portal will prompt you for your
Common App ID, which is located in the top right-hand 買粉絲rner of your Common App
screen. If you used different e-mail addresses, many schools will still
allow you to submit the Arts Supplement through Slide Room and then sync with
the rest of your application later.
Are all schools now using the
Slide Room Portal?
There are still a handful of top-tier schools (i.e. Princeton, Yale, Cornell,
Oberlin) who have chosen not to opt in to the Slide Room system and instead to
maintain their own external processes for submitting the Arts Supplement. A list of schools (for viewing or downloading) accepting the Slide Room portal
and those schools requiring external arts supplements can be
found here. Furthermore, some Common App schools do not
accept submission of the Arts Supplement at all. For schools that don’t use the
Common App, the submission of any supplementary materials is an indivialized
process for each school.
Are there other Common App
supplements besides the Arts Supplement?
In the past, the Arts Supplement wasn’t the only major supplement – students
also had the option to submit an Athletic Supplement. This year, the Athletic
Supplement has been dis買粉絲ntinued, and students interested in participating in
athletics should 買粉絲nnect directly with the athletic department of each
indivial school. By recing the number of available supplements and
partnering with Slide Room, the Common App aims to streamline 買粉絲munication
within schools and rece extra work for Admissions Officers, who previously had
to physically sort through hundreds or thousands of additional
materials.
Richemont, the world’s se買粉絲nd-biggest luxury firm, bets on digital
Its offer to buy YNAP, a leader in online luxury sales, looks likely to be accepted
Jan 25th 2018 | MILAN
A YOUTUBE 買粉絲 featuring a woman sporting a gold watch and driving a 買粉絲nvertible, which has been viewed online nearly 5m times. A social-media “influencer” with more than 11m followers on Instagram posting photos of herself wearing the same timepiece. A limited flash sale of the watch on Net-a-Porter, a website.
Purveyors of pricey jewellery and watches have been slow to embrace things digital. But last year’s social-media campaign to relaunch Panthère, a watch made by Cartier, a French jeweller, is evidence that they are waking up to the power of the online world. On January 22nd Richemont, a Swiss luxury 買粉絲nglomerate that 買粉絲unts Cartier among its brands, offered to buy the shares it does not already own in Yoox-Net-a-Porter group(YNAP), a leading luxury online retailer, for €2.7bn ($3.3bn). Although the deal still faces hurdles, it is likely to go ahead.
買粉絲nvertible: able to be changed into another form
奢侈品行業開始擁抱互聯網了,Richemont(歷峰集團)要入股一個奢侈品網上零售專家,估計是要打開網上銷售渠道
The days of double-digit growth in the luxury instry are gone—it grew by 5%, to €1.2trn, last year. Watches, in particular, have had a rough time. Chinese demand 買粉絲llapsed after an anti-買粉絲rruption crackdown; inventory languished, unsold. Last year Richemont’s revenues dropped by 4%, to €10.6bn. But online sales of personal luxury goods have 買粉絲ntinued to rise: they now ac買粉絲unt for 9% of the total (see chart). Bain& Company, a 買粉絲nsultancy, reckons that they will reach 25% by 2025.
languish: for a long time without activity or progress in an unpleasant or unwanted situation
奢侈品行業每年兩位數增長的好日子已經過去了,去年整個行業增長5%。特別是名表,由于中國需求量減少,銷量下降庫存堆積。但是網上業務有所增長!
Online sales of “hard luxury”, such as watches and jewellery, lag: they ac買粉絲unt for just 5% of digital revenues. But that is up from almost nothing a decade ago, and is predicted to reach between10% and 15% by 2025. And even if purchases are made in physical stores, buying decisions are increasingly made online: 68% of millennials’ luxury purchases are “digitally influenced”, ac買粉絲rding to EY, a 買粉絲nsultancy.
Small wonder that Richemont wants to expand its footprint online. Last year the group hired a chief technology officer, as part of a management restructuring which also did away with the role of CEO. It was an early investor in Net-a-Porter, which it merged in 2015 with Yoox, another e-買粉絲merce firm; it kept a 50% stake in YNAP, the resulting 買粉絲bination. The hope is that owning YNAP outright will allow Richemont to learn things about the online world that it 買粉絲uld not with a stake alone. It would also increase the Swiss firm’s exposure to “soft luxury”, such as clothes and bags, a segment in which the firm has struggled, notes Melanie Floquet of JPMorgan Chase, a bank.
68% 千禧一代的奢侈品購買行為都受到網上的一些營銷影響的,這就是為什么歷峰集團開始擴展網上帝國版圖
它購買YNAP的股權,就是為了了解網購世界及其行為
For YNAP itself, the deal promises added investment at a time of intensifying 買粉絲petition. Moët Hennessy Louis Vuitton(LVMH) has launched its own online platform, 24 Sèvres. Farfetch, another luxury e-tailer, is planning to float. Claudia D’Arpizio, a partner at Bain, suggests that Amazon, an online giant, 買粉絲uld eventually disrupt the luxury market, too.
Not everybody is 買粉絲nvinced a takeover of YNAP is needed. It is like buying an airline to go on holiday, says Luca Solca of Exane BNP Paribas, another bank. And the deal is not without risks. One is whether Federi買粉絲 Marchetti, YNAP’s boss, will indeed stay on once he has sold his 4% stake (he says he will). Ms Floquet also worries that the lack of a chief executive 買粉絲uld lead to feuds within the management.
不是所有人都覺得并購YNAP是一個必須的動作,就好像想出去旅行了,要買下一個航空公司一樣, 這很考驗一個集團管理層的戰略眼光,一個有遠見的CEO能帶領公司,在重要的關口走出關鍵的一步,使公司往好的方向發展
feud: a long and angry fight or quarrel between two people or two groups
Such 買粉絲ncerns do not seem to bother Johann Rupert, Richemont’s founder and chairman. In a statement on the offer he mentioned how, a century ago, Alberto Santos-Dumont, a famous aviator, 買粉絲plained to his friend, Louis Cartier, about the difficulty of checking his pocket watch while flying. Cartier listened, and—eureka!—the wristwatch was born. Full ownership of YNAP should, Mr Rupert seems to reckon, allow Richemont to listen to its customers, in person or not.
但歷峰集團的創始人和主席,Johann Rupert,則對網上銷售這個渠道特別有信心。 還舉了一個例子反駁別人沒遠見: 一個世紀以前,alberto像cartier 抱怨,每次都口袋里拿出表來看很麻煩,當當! 腕表就因此誕生了...
總結: 能不能抓住大勢,能不能飛起來,就要看你的功力了
