A major trend in 2010s movie advertising (and occasionally trailers for other media) is using a famous upbeat pop song to set the mood, only recontextualized with dark, atmospheric music and most often sung by a breathy female vocalist singing at the lower end of her range. Typically, these songs use bright cheerful pop songs with deceptively unhappy lyrics, which the new versions attempt to underline. This can also be used for advertising derivative works; a famous song from the source material can be repurposed into something slower and moodier to indicate that it's going to be Darker and Edgier.
Compare Ironic Nursery Tune. Usually a Softer and Slower Cover.
Examples:
- Most articles credit The Social Network's use of a children choir singing Radiohead's "Creep" as the Trope Codifier. Unlike most later examples, however, the original is not very upbeat.
- The 2014 adaptation of Endless Love uses Robert Palmer's '80s hit "Addicted to Love," emphasizing the insanity of love.
- Dracula Untold's trailer uses Lorde's cover of Tears for Fears's "Everybody Wants to Rule the World."
- A trailer for Geostorm features a slow, creepy cover of Louis Armstrong's "What a Wonderful World" sung by a mournful female voice. There's meant to be a juxtaposition between the sweetly optimistic lyrics and the gratuitous scenes of Monumental Damage and at the hands of the Hostile Weather.
I see skies of blue and clouds of white*dozens of tornadoes bearing down on a village as terrified people flee for their lives*The bright blessed day, the dark sacred night*30 story tall tsunami sweeps through a coastal city, toppling buildings like dominoes*And I think to myself what a wonderful world.*birds falling out of the sky, followed by an airplane careening wildly towards the ground*
- Insurgent: The Film of the Book also uses a moodier cover of Louis Armstrong's happy "What a Wonderful World" ironically, as much destruction goes on in the trailer as it plays.
- The Russian doping documentary "Icarus" uses a moody cover of CAKE's "The Distance," an alt-rock song about an obsessed race car driver.
- Beyoncé recorded a whole new remix of her own "Crazy in Love" as a promotion for Fifty Shades of Grey.
- San Andreas, a movie about an earthquake wiping out San Francisco, used Sia's slow ironic cover of "California Dreamin'".
- A Cure for Wellness used an ironic cover of punk legends The Ramones' iconic "I Wanna Be Sedated" by Mirel Wagner. The use of drugs and sedatives figures heavily in the movie.
- The teaser trailer for Power Rangers (2017) featured Halsey's graver, more ambient cover of Johnny Cash's upbeat "I Walk the Line."
- Blair Witch featured a cover of The Police's already-creepy Obsession Song "Every Breath You Take."
- The Great Gatsby (2013) had Filter's cover of '60s pop classic "Happy Together" by The Turtles.
- An example that also appeared in the movie; the trailer for Avengers: Age of Ultron featured a woman, and later Ultron himself singing a slow, creepy cover of the ebullient "I've Got No Strings" from Pinocchio, as both are Artificial Humans, but Ultron turned against his masters.
- In-universe example: The Killing of a Sacred Deer featured the main character's daughter singing an a capella cover of Ellie Goulding's "Burn," taken from a scene in the movie.
- Pride and Prejudice and Zombies featured an atmospheric cover of "Born to Be Wild." Presumably this is referring to Elizabeth Bennet being a badass.
- Logan used Johnny Cash's version of the Nine Inch Nails song "Hurt" (one of the few examples where the cover version was already well known) in many of its trailers.
- Tomb Raider (2018) goes with a cover of Destiny's Child's "Survivor." Lara is indeed a survivor.
- Suicide Squad (2016) features Becky Hanson's slow, haunting cover of The Bee Gees' "I Started a Joke" in its trailer, because the film features The Joker and Harley Quinn, and the lyrics mock the titular Suicide Squad's lack of agency as Boxed Crooks. The original version is more of a soul ballad.
I couldn't seeThat the joke was on me
- Wrath of the Titans used a cover of the Eurythmics' "Sweet Dreams (Are Made of This)", specifically Marilyn Manson's already-famous, much angrier-sounding version.
- A Wrinkle in Time (2018) used a different cover of the aformentioned song in order to set the fantastic tone of the film.
- X-Men: Apocalypse used Clairity's slow cover of Coldplay's "Don't Panic" in the trailer. The original was already fairly somber, but trailer milks the slower, more intense rendition of the lyric "We live in a beautiful world" repeatedly to highlight the irony that Apocalypse is destroying it.
- A Walk Among the Tombstones used a cover of Soundgarden's "Black Hole Sun".
- The trailer for Crimson Peak featured PJ Harvey's cover of Nick Cave's "Red Right Hand."
- Alien: Covenant featured Aurora's atmospheric cover of David Bowie's "Nature Boy" in its teaser trailer.
- Ready Player One has a variation. The cover of "Pure Imagination" from Willy Wonka & the Chocolate Factory by Ghostwriter Music fits this trope with the lyrics used, as they are sung slowly and infused with electronica, but the track itself gets more and more bombastic in the instrumental portion. The song is fitting, as the film is about a virtual world where nearly anything is possible.
- Justice League (2017) used a grungy cover of David Bowie's "Heroes" by Gangs of Youth, since the film is about superheroes coming together.
- The commercials for the Dwayne Johnson movie Skyscraper uses a slow cover of Tom Petty's "I Won't Back Down."
- HBO's ads for their Bernie Madoff TV-movie The Wizard of Lies features a dark cover of The Police's "King of Pain" by Valerie Broussard.
- Dumbo (2019) has a cover of the original film's Signature Song "Baby Mine" play during the trailer. This particular cover doesn't appear in the remake itself, but Arcade Fire did cover the song for the closing credits.
- The trailer for Us has a sinister remix of Luniz's "I Got 5 On It", with the melody played higher to resemble "Psycho" Strings. This theme also appears in the film.
- The first trailer for Child's Play (2019) makes use of Harry Nilsson's "Best Friend".
- Rambo: Last Blood: The trailer uses a somber cover of Lil Nas X's "Old Town Road".
- The first trailer for Candyman (2020) uses a slowed down version of Destiny's Child's "Say My Name". In this case, it's a remix instead of a cover.
- Another remix-instead-of-cover version, courtesy of Smashing Pumpkins, is used for the Watchmen trailer (incidentally, the original also graced a DC superhero movie, Batman & Robin).
- The trailer for The Craft: Legacy features a slower, more somber cover of "Girls Just Wanna Have Fun".
- Star Trek: Discovery used a cover of "I'd Love To Change The World" by Ten Years After.
- At least one of the trailers for American Horror Story: Coven used a slow-paced version of "House of the Rising Sun".
- The trailer for The Defenders (2017) included a slow version of Nirvana's "Come As You Are".
- Hannibal: Season two's trailer used MONA's warped version of Ben E King's "Stand By Me" to emphasize the main characters' complicated relationship.
- The trailer for The Whispers has "You Are My Sunshine" playing like a nursery rhyme.
- Game of Thrones: The teaser trailer of season seven used a slow version of "Sit Down" by James where the coda of the song is used to show the state of the three rulers of the Seven Kingdoms (Jon Snow, Daenerys Targaryen and Cersei Lannister) who are walking towards their thrones.
- The trailer for the third season of The Magicians also uses Valerie Broussard's more mournful-sounding, breathy-voiced version of The Police's "King Of Pain".
 To completely be this trope, it's done by a female singer in a low voice.
- As with as Dracula Untold, Lorde's "Everybody Wants to Rule the World" was also used by Assassin's Creed: Unity, which came out the same year.
- The trailer for the video game Dead Space featured a woman singing "Twinkle Twinkle, Little Star" in a way that sounded like she was on the verge of tears.
- Commercials for Evolve feature Mischa feat. Esthero's cover of "Ready Or Not" by The Delfonics. The cover only includes the chorus, which emphasises the dark and frightening feel of the game. Another trailer uses Lissie's cover of Danzig's "Mother", which spends about two thirds of the song being more slow and mournful before escalating into the rapid-fire final riff.
- Florence + the Machine did a cover of Ben E King's "Stand by Me" for Final Fantasy XV. It is a bit slower than the original, but more soulful and bombastic.
- An early example is the Gears of War "Mad World" trailer, which uses Gary Jules's cover of the Tears for Fears song. Although this cover was originally used on the soundtrack for Donnie Darko.
- The Evil Within 2 uses a dark and bittersweet cover of Duran Duran's "Ordinary World" prominently in the trailer. It also features in the finished game as the ending credits theme.
- Parodied in "How To Make A Blockbuster Movie Trailer" by Auralnauts, with a cover of Dead or Alive's "You Spin Me Round (Like a Record)."
- She-Ra and the Princesses of Power does this in the Season 5 trailer with its own theme song, "Warriors." The song is covered by AJ Michalka of Aly & A.J., who is also the voice of Catra on the show. While the original is more upbeat and empowering in tone, the cover is slower and grimmer, reflecting the escalating conflict heading into the final season.
- One commercial for Alfa Romeo uses an atmospheric cover of Chris Isaak's "Wicked Game."
- Parodied, and crossed with Ironic Nursery Tune, with the satire website Hard Drive in the article "Movie Trailer Editor Struggling to Create Menacing Rendition of Mary Had a Little Lamb".
When people see this trailer, we want them to have nightmares about it, said Lionsgate marketing head Damon Wolf.


Take your SMILE Test
Sensitive teeth can be a burden for many people and can be caused by several things. It is always important to seek advice from a dental professional so the source of the problem can be identified and treated. One cause of sensitivity is dental erosion, which is the loss of tooth enamel.
Great! You are good at Maintaining a fresh breath, Prevent gum disease and also Remove teeth stains.
Regular use of dental floss removes plaque, helping to prevent the buildup of plaque, which can lead to tartar. Simply flossing your teeth can make them look brighter by removing plaque and excess food particles that you may not see in the mirror or in areas that your toothbrush doesn’t reach.
A toothpick should only be used to dislodge large food particles between teeth. It should be used in a way so that the gums or teeth are not harmed. If you have large spaces where food gets caught constantly you can talk to your dentist about ways to close them.

GODS AND MONSTERS
Reviewed by Harvey Karten, Ph.D. Lion's Gate Films Director: Bill Condon Writer: Bill Condon, novel Father of Frankenstein by Christopher Bram Cast: Ian McKellen, Brendan Fraser, Lynn Redgrave, Lolita Davidovich, Kevin J. O'Connor, David Dukes, Brandon Kleyla, Jack Plotnick
Irving Berlin knew that there's no business like show business and Bill Condon does his bit to prove it. In one scene of "Gods and Monsters," Condon's fanciful and splendidly realized adaptation about the last days of "Frankenstein" director James Whale, the impresario of horror insists that there's no joy in the world that compares to that of directing films. Condon creates an inventive tale of this important figure's views, work and memories. And why not? In 1957 his subject was found dead in his pool like "Sunset Boulevard"'s Norma Desmond. His departure was listed as "under mysterious circumstances."  Christopher Bram covered his life story in his book "Father of Frankenstein," which forms the basis of Condon's screenplay.
Unlike the conventional biopic "Without Limits" about track athlete Steve Prefontaine, "Gods and Monsters" does not play to the grandstands. It unfolds instead as a mostly serene probing of the director's mind in his final days, a period highlighted by his recollections of a better time and by an unusual friendship between him and the young man he hires to mow his lawn. The victim of a stroke which left his motor ability untouched but which caused neurological electrical storms in his brain, Whale was confronted daily with the choice of taking a prescribed drug which zonked him out or of avoiding the medicine, which caused his mind to go off in a hundred directions. Like the stroke-afflicted character Emily Stilson in Arthur Kopit's play "Wings," Whale endures an ailment which causes memories, both pleasurable and distressing, to flood his faculties. Through a brief, unusual friendship with a working-class stiff, he recalls his direction of Elsa Lanchester as the "Bride of Frankenstein" while Condon frequently breaks away from the narrative to offer up snippets of scenes from that accomplishment.
The film is superbly acted by Ian McKellen, one of the world's foremost thesps, who is encased in a large home on California's Pacific Palisades but has lost his capacity to enjoy. He looks in the mirror at his old but distinguished features, runs a comb slowly and lovingly through his silky white hair, and for the most part appears to us as a mellowed-out venerable chap. His calm makes his bursts of rage all the more alarming, as in Condon's imaginative view he taunts a robust young man, begging to be killed. Such moments of privacy are rare as he is under the watchful eye of his servant of fifteen years, the Hungarian-born Hanna-- who is portrayed as woman with unconsciously comic repartee by Lynn Redgrave, made over to look about seventy years of age and wearing a perpetual scowl.
In an unusual and marginally dangerous bit of casting, Brendan Fraser, known to a large audience as a sweet, comic personality in "George of the Jungle" and "Encino Man," provides the catalyst for the older man's reveries. Handsome and muscular, Clayton Boone (Fraser), a drifter who accepts odd jobs in tony California neighborhoods, could not help reviving Whale's dormant sexuality, belying a popular view that senior citizens do not think of sex. Rather, as one knowing person suggests, they think of nothing BUT sex. Boone poses for Whale's sketches, at first seeming to tolerate his new employer's homosexual background ("live and let live") but soon becomes enraged when the man makes ribald suggestions about the armies of folks who'd cavort naked under his roof and at his swimming pool.
Director Bill Condon seamlessly weaves visions of the old man's fancy into his drama of his subject's deterioration, following clips from "Bride of Frankenstein" with a reenactment of Whale's direction of the movie. He creates a mood that lets us imagine what it might be like to be going through a neurological crisis, blending 1950s reality with the moviemaking of the 1930s. It does not take long to realize that the muscular Brendan Fraser is pictured by Whale as the Frankenstein monster, a creature who is treated sympathetically and with a great dry wit in Whale's movies. The monster is the lonely outsider in a world he can scarcely understand. In Condon's most comical scene, Whale embarrasses gay director George Cukor and Princess Margaret at a house party by introducing his gardener--like the monster, an outsider to this milieu--which we see as one of Whale's futile attempts to break through his own vulnerability.
Money isn't everything. Like "Sunset Boulevard"'s Norman Desmond, Whale is shown to lack nothing in material comforts. But he no longer uses the pool, which was the locus of so much of his enjoyment in his earlier days. His career junked two decades back with the failure of his movie "The Road Back," Whale might as well be living in the England of his childhood, a youth of poverty whose diet consisted of drippings. Ian McKellen, who cannot turn in a bad performance, is quietly riveting throughout, no longer the misanthrope of Christopher Bram's novel but a sympathetic soul who justifiably captivates our compassion. Not Rated. Running time: 105 minutes. (C) Harvey Karten 1998

These examples show the use of the MPI_GET function. As all MPI RMA communication functions are nonblocking, they must be completed. In the following, this is accomplished with the routine MPI_WIN_FENCE, introduced in Section Synchronization Calls .
Example
We show how to implement the generic indirect assignment
A = B(map), where A,
B, and
map have the same
distribution, and map is a permutation. To simplify, we assume
a block distribution with equal size
blocks.
SUBROUTINE MAPVALS(A, B, map, m, comm, p) USE MPI INTEGER m, map(m), comm, p REAL A(m), B(m) INTEGER otype(p), oindex(m), & ! used to construct origin datatypes ttype(p), tindex(m), & ! used to construct target datatypes count(p), total(p), & disp_int, win, ierr INTEGER (KIND=MPI_ADDRESS_KIND) lowerbound, size, realextent, disp_aint ! This part does the work that depends on the locations of B. ! Can be reused while this does not change CALL MPI_TYPE_GET_EXTENT(MPI_REAL, lowerbound, realextent, ierr) disp_int = realextent size = m * realextent CALL MPI_WIN_CREATE(B, size, disp_int, MPI_INFO_NULL, & comm, win, ierr) ! This part does the work that depends on the value of map and ! the locations of the arrays. ! Can be reused while these do not change ! Compute number of entries to be received from each process DO i=1,p count(i) = 0 END DO DO i=1,m j = map(i)/m+1 count(j) = count(j)+1 END DO total(1) = 0 DO i=2,p total(i) = total(i-1) + count(i-1) END DO DO i=1,p count(i) = 0 END DO ! compute origin and target indices of entries. ! entry i at current process is received from location ! k at process (j-1), where map(i) = (j-1)*m + (k-1), ! j = 1..p and k = 1..m DO i=1,m j = map(i)/m+1 k = MOD(map(i),m)+1 count(j) = count(j)+1 oindex(total(j) + count(j)) = i tindex(total(j) + count(j)) = k END DO ! create origin and target datatypes for each get operation DO i=1,p CALL MPI_TYPE_CREATE_INDEXED_BLOCK(count(i), 1, & oindex(total(i)+1:total(i)+count(i)), & MPI_REAL, otype(i), ierr) CALL MPI_TYPE_COMMIT(otype(i), ierr) CALL MPI_TYPE_CREATE_INDEXED_BLOCK(count(i), 1, & tindex(total(i)+1:total(i)+count(i)), & MPI_REAL, ttype(i), ierr) CALL MPI_TYPE_COMMIT(ttype(i), ierr) END DO ! this part does the assignment itself CALL MPI_WIN_FENCE(0, win, ierr) disp_aint = 0 DO i=1,p CALL MPI_GET(A, 1, otype(i), i-1, disp_aint, 1, ttype(i), win, ierr) END DO CALL MPI_WIN_FENCE(0, win, ierr) CALL MPI_WIN_FREE(win, ierr) DO i=1,p CALL MPI_TYPE_FREE(otype(i), ierr) CALL MPI_TYPE_FREE(ttype(i), ierr) END DO RETURN END
Example
A simpler version can be written that does not require that a
datatype be built for the target buffer. But, one then needs a
separate get call for each entry,
as illustrated below. This code is much simpler, but usually much less
efficient, for large arrays.

Camera Shake Volume Components
Camera shake volumes are used to place regions in a scene where a player's camera should vibrate. This is used in conjunction with camera shake components. The volumes have no effect on their own, instead the camera shake component will check whether it is inside such a volume, and apply its shake effect accordingly.
Shared Component Properties
All camera shake volumes share these properties:
Strength
: How much shake to apply when the camera is at the strongest point inside the volume (for a sphere that would be right at the center). This is a factor between 0 and 1, scaling the camera shake between theMinShake
andMaxShake
value of the camera shake component.BurstDuration
: If zero, the shake is indefinite. Otherwise it is active for only a limited duration. This would be used for effects like explosions that should only last a short time.OnFinishedAction
: If used as a burst, the component or entire object may get deleted afterwards.
Camera Shake Volume Sphere Component
This camera shake volume defines a spherical volume. The shake is strongest at its center and gradually fades out towards its edge.
Sphere Component Properties
Radius
: The radius of the sphere volume.


The Line Agency project is a single agent algorithm that determines the scalable value of angles for each canvas boundary (i.e. the walls of the canvas). To determine the angle, trigonometry is applied to calculate the agent's trajectory (i.e. xPos += cos(radians(angle)) * stepSize;). In conjunction to this, a function with conditional statements are also used. Within those statements are the set trajectory which are triggered once the agent has landed on the appropriate angle.

[web-scraping] Job Hunting Like A Data Analyst (Part I)
Motivation:
I’m currently suffering a tough time in looking for a data analyst job.
Instead of doing it in a traditional way, I am thinking why not do the job hunting just like a data analyst, by making use of the advantages of data science.
Always, the first step to flight a battle is to know your enemy. As I’m looking for a job in Singapore/China, the first thing I would like to explore is the job market in these areas.
I’m interested to know about:
- Who is hiring data analyst
- Which cities need data analyst most
- What skills are expected
- How is a data analyst described
What I will do is to start with LinkedIn Job Search to find the job posting about Data Analyst, using data science of course!
Information Collection:
What You Need:
- Python 2.x
- Chrome/Firefox Browser
- package urllib2
- package bs4

The basic idea is to get URL for the first page and download the content of page. Then get the URL of next page and repeat.
2. Mimic to Browsers
Sometimes the web server won’t recognise the python browser and hence it is always a good practice to mimic as another popular web browser when doing the web scraping. urllib2
has a ‘headers’ parameter, which can be used to define the browser.
3. Setting a Delay
Most websites don’t like web spiders and will prevent too frequent request from the same IP address. So it is better to set a time delay between each request.
4. Parsing HTML
After downloading the html of the page, we are not going to store it directly. Instead we will extract the useful information (e.g. text, links), store it and throw away the page html.
5. Saving into Data File
After the information is extracted, we output the data into csv/txt file for easier future use.
Scraping LinkedIn Job Search
To find the job post on LinkedIn is simply go to LinkedIn Job Search site and input keywords data analyst and Singapore, and then website will direct us to a new URL: “https://sg.linkedin.com/job/data-analyst-jobs-singapore/”, which is more or less like the screenshot below. Instead of browsing every page to look for the ideal job post, I would like to use python to browse the pages for us.
Fetch the first page
Using python urllib2 package, we can simply write a function to send HTTP request, download the page, read the content and parse the html to return the response.
import urllib2
from bs4 import BeautifulSoup
def getResponse(url):
user_agent='Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:39.0) Gecko/20100101 Firefox/39.0'
headers={'User-Agent':user_agent}
# define the request
request=urllib2.Request(url,headers=headers)
# request, download and read the content
response=urllib2.urlopen(request).read()
# parse the html using BeautifulSoup
response=BeautifulSoup(response)
return response
It is import to include a header of user-agent in the request, otherwise you will get an error saying request is denied. To find the header information, you can go to Firefox->Tools->Web Developer->Network and it is under the header tab.
Extract the useful information
Now we already have the html file ready and we can use BeautifulSoup findAll/findNext function to filter by the html tag. For example, when we need to get the Job Title from the page, we can use Firefox inspector (Firefox->Tools->Web Developer->Inspector) to easily locate the element.
By pointing to the job title, the h2 tag is highlighted.
We can just call findNext/findAll(‘h2’).text to extract the text in h2 tag. Similarly we can call findNext/findAll(‘h2’)[‘href’] to extract the attribute, which is the link of the job post in this case.
There are many possibilities of h2 tags other the job titles, so I would like to refine the selection to the job post main content by filtering (‘ul’,{‘class’:’jobs’}), which means ul tag with attribute ‘class’ and value ‘jobs’.
Within the job post content, we do another selection by filtering (‘ul’,{‘class’:’jobs’}) and it will generate a list of html contains 25 elements.
bassurl = 'https://sg.linkedin.com/job/data-analyst-jobs-singapore/'
## get the response html from the page
response=getResponse(baseurl)
## refine the selection of job posting
content=response.findAll('ul',{'class':'jobs'})[0]
## select job lists
jobs=content.findAll('li',{'class':'job'})
In order to get the basic information of job title, link, company name, post date and company location, I defined 4 functions to loop over the jobs
list.
Using encode(‘utf-8’) can prevent the encode error, when writing the data into csv file.
def getTitle(x):
return x.findNext('h2').text.encode('utf-8')
def getLink(x):
return x.findNext('h2').findNext('a')['href']
def getCompany(x):
return x.findNext('a',{'class':'company'}).text.encode('utf-8')
def getDate(x):
return x.findNext('span',{'itemprop':'datePosted'}).text.encode('utf-8')
def getLocation(x):
return x.findNext('span',{'itemprop':'addressLocality'}).text.encode('utf-8')
The last and important information we need to get is the URL of next page, so that we can automatic the web scraping. try/except in python means to run the try clause and run the except clause only if error occurs. This is added in case the loop comes to the last page.
def getNextPage(page):
try:
return [p['href'] for p in page if 'next' in p['href']][0]
except:
return None
Store the data
There are some types of collection in python, e.g. list, set, dictionary, tuple, among which we are going to use combination of list and dictionary to store the data. Because it is more convenient to write to csv file using DictWriter function or easier to convert to pandas DataFrame type.
The format of python dictionary is {key1:value1,key2:value2,…}. Each record of the data will be a dictionary with the column names as the key and information as the value.
Then each dictionary will be appended as a list to form a collection.
Here an additional valid function is introduced, because some information may be missing for certain record and it will return None if such case happens.
data=[]
for i in jobs:
row={}
row['title']=valid(getTitle,i)
row['company']=valid(getCompany,i)
row['date']=valid(getDate,i)
row['location']=valid(getLocation,i)
row['link']=valid(getLink,i)
data.append(row)
def valid(fn,x):
try:
return fn(x)
except:
return None
Put them together
We now have all the pieces ready and we can write a function called fetchPage
to group them together.
def fetchPage(baseurl):
response=getResponse(baseurl)
## page body of job posting
content=response.findAll('ul',{'class':'jobs'})[0]
## page navigation bar
page=response.findAll('div',{'class':'pagination'})[0].findAll('a',{'rel':'nofollow'})
## job lists
jobs=content.findAll('li',{'class':'job'})
## get url for next page
nextPageUrl=getNextPage(page)
## store information into list data
data=[]
for i in jobs:
row={}
row['title']=valid(getTitle,i)
row['company']=valid(getCompany,i)
row['date']=valid(getDate,i)
row['location']=valid(getLocation,i)
row['link']=valid(getLink,i)
data.append(row)
return data,nextPageUrl
Loop it over the pages
Since we already have the function to return the data and URL of nextPage, we can just write a for
loop to get as many pages as we want.
One thing to mention is that a time delay is recommended to set between the requests. In python, we can use time.sleep(x)
function from time module, which means pause the program for x seconds. A constant time interval may look more like a robot, so I set the delay time to be a random variable. It can be accomplished by random.random()
function, which generates a [0,1) float number.
import time
import random
def setDelay(n):
print 'wait ~'+n+' seconds ...'
## I set +/- 20% range of randomness
delay=(0.8+0.4*random.random())*n
time.sleep(delay)
Loop the `fetchPage’ function, we will have the code like:
def fetchPages(baseurl,path,nPages=3):
print 'Start:'
data0,nextPageUrl=fetchPage(baseurl)
print 'Page 1 completed'
if nextPageUrl:
pass
else:
return 'nextUrl is missing in first page!'
for i in range(2,nPages+1):
if nextPageUrl:
setDelay(5)
data,nextPageUrl=fetchPage(nextPageUrl)
print 'Page '+str(i)+' completed'
data0+=data
else:
print 'nextUrl is missing in page '+str(i)+'!'
break
write_csv(data0,path)
print 'Writing data to '+path+' is done!'
return data0
Write to csv
If you carefully exam the code in previous section, you will noticed the write_csv
function is actually not yet defined.
Here is the code, which uses csv.DictWriter
to write into csv file row by row.
def write_csv(data,path):
fieldnames=data[0].keys()
with open(path,'w') as csvfile:
writer=csv.DictWriter(csvfile,fieldnames=fieldnames)
writer.writeheader()
for i in data:
writer.writerow(i)
Browsing hundreds of job post is just as simple as one sentence:
data=fetchPages(url, '.../data.csv',nPages=20)
Now you already got the 500 job posts in 2 mins!


Introduction
Taxonomies are the Spree system’s approach to category trees. The heading of a tree is called a Taxonomy. Any child branches are called Taxons. Taxons themselves can have their own branches. So you could have something like the following categories structure:
In this example, “Categories” is the name of the Taxonomy. It has three child branches - “Luggage”, “Housewares”, and “Clothing”. The last two branches each have three of their own child branches. Thus, “Clothing” is a child taxon to “Categories” and a parent taxon to “Men’s”.
To reach the Taxonomies list, first go to your Admin Interface, then click “Configurations” and “Taxonomies”.
Create a New Taxonomy
To create a new taxonomy, click the “New Taxonomy” button. Enter a name for the taxonomy and click “Create”.
You can then add child taxons to your new taxonomy.
Edit a Taxonomy
To edit an existing taxonomy, click the “Edit” icon next to the name in the Taxonomies list.
Here, you can change the name of the Taxonomy. You can also reorder the child taxons, delete a taxon, add a new taxon, or edit a taxon. Make your changes, then click the Update button.
Delete a Taxonomy
To delete a taxonomy, click the “Delete” icon next to the name in the Taxonomies list. Click “OK” to confirm.
Adding a Taxon to a Taxonomy
Once you have created a taxonomy, you may want to add child taxons to it. Do do this, right-click the name of the Taxonomy, and click “Add”.
This will cause a new input field to open up, with “New node” in it. Replace this text with the name of your new taxon, and hit Enter. You’ll now see the child tax in the taxonomy tree.
Click “Update” to save your addition.
Adding a Taxon to Another Taxon
If your site needs sub-trees, just add taxons to other taxons. To do so, right-click the name of what will become the parent taxon, and click Add.
Enter the name of the child taxon and click enter. Repeat this process for any sub-trees you need.
Remember to save your changes by clicking the “Update” button after you have added any taxons.
When you navigate away from your taxonomy’s page, then navigate back to it, sub-trees will be collapsed by default. To see child taxons, just click the arrow next to the parent taxon.
Reorder a Taxon
Taxons are displayed in the order you add them by default. To reorder them, just drag and drop them to their correct location in the tree.
Let’s assume, for example, that we want the “Children’s” taxon to be listed first, above “Women’s” and “Men’s”. Just drag and drop the taxon to its new location.
You can even drag a parent taxon into the tree of a different parent taxon, merging it into the second taxon’s sub-tree.
Edit a Taxon
To edit a taxon’s name, just right-click it and click “Edit”.
Here, you can edit several aspects of the taxon:
- Name - A required field for all taxons. The name determines what the user will see when they look at this product in your store.
- Permalink - The end of the URL a user goes to, in order to see all products associated with this taxon. This field is also required, and a value is automatically generated for you when you create the taxon. Be careful with arbitrarily changing the permalink - if you have two taxons with the same permalink you will run into issues.
- Icon - This option is currently not functional.
- Meta Title - Overrides the store’s setting for page title when a user visits the taxon’s page on the front end of the website.
- Meta Description - Overrides the store’s setting for meta description when a user visits the taxon’s page on the front end of the website.
- Meta Keywords - Overrides the store’s setting for meta keywords when a user visits the taxon’s page on the front end of the website.
- Description - This option is currently not functional.
Remember to click “Update” after you make your changes.
Delete a Taxon
To delete a taxon, right-click it in the taxonomy tree and click “Remove”.
Click “OK” to confirm.
Associating Products with Taxons
To associate a product with one or more taxons, go to the Admin Interface, and click the “Products” tab. Locate the product you want to edit, and click its “Edit” icon. Select the taxons for the product in the Taxons field.
