House prices and roller coasters

Is the statistics boring? Is data visualization boring? Is simulated programming boring? You still have to see what people do and how they do it. The following video uses the first-view roller coaster to show us house prices since 1890. There is no end to imagination. Drunk piano said happiness can not be asked, enrich can not be met. Changing "enrichment" to "fun" is not a problem.

 

P.s ., since the three-Table recommendation is so cool, the input method is highly viscous, and no one wants to give up the self-built dictionary that has accumulated hard work, Google and sougo are eager to use the input method to seize the market, why does no one provide the ability to automatically import other Input Software Word libraries? Isn't it that difficult to reverse engineer the word library? Is it illegal for China to import files for other products? Example:

Black Horse Input Method: taste the meat, and know the taste
Sogou Input Method: it is recommended to make a mess, but to or for a job

Black Horse Input Method: Che Xiaoyu, Ma Xiaoxiao, and his arrows are on the waist
Sogou Input Method: chellinlin, do you have a small font?

Black Horse Input Method: Never dead, keep Dan's heart and history
Sogou Input Method: No one is dead in your life.

Black Horse Input Method: qingqingzixiao
Sogou Input Method: qingqingzixiao

Dark Horse Input Method: my generation is not from pengan.com
Sogou Input Method: I am discriminated against Peng haoren

Black Horse Input Method: ear monitoring, non-profit basket
Sogou Input Method: Step 2, should not be the case

Black Horse Input Method: Landscape drag thousands of miles away, the building is five clouds high. In the glorious days and months of garden repairs, Jing won the post's accomplishments.
Sogou input method: the exception of landscape constant arrearage is that the building is full of dark clouds. In the glory of the original show Sun and the Moon, many articles were made in chemical industry.

P.p.s. It is not harmful to know too much or know too little. Not much worth it. Sometimes it is very dangerous, for example, dailywtf (worst than failure, not what the f * @ # &, don't think about it) the old man who holds high praise for Unix philosophy used the following statement to calculate the file size: my $ filesize = 'wc-C $ file | cut-c0-8 | SED's // g '';

Actually, we only need $ filesize =-S $ File

P.p.p.s, what is strong expressiveness? What is this? Operator = use infinite words

Planets = ['mercury', 'venus', 'global', 'mars', 'Jupiter ', 'saturn', 'uranus', 'neptune']
Dwarf_planets = ['ceres', 'pluto', 'eris ']

Case Body
When * planets
Puts "# {body} is a planet"
When * dwarf_planets
Puts "# {body} is a dwarf planet"
End

What about this? Suppose we want to define the factory method in a class and generate an empty instance of this class. Can the following code be used? Answer: If a is inherited by a subclass, this method becomes invalid because a. New does not include the definition of the subclass. However, since ruby is dynamic, there should be an elegant solution: Self. Class

# Bad method Class
Def create_empty_instance
A. New # =>
End
End # Good method class A def create_empty_instance self. Class. New end

P.p.p.p.p.s. Be honest. I have a thesis to prove it: here, and here. The conclusion in the first paper is that the CEO often put a lot of energy into the show-up activities after the grand prize becomes the media's favorite social star, and the company's performance is mostly declined. The conclusion in the second paper is that the more luxurious the CEO's house is, the worse the company's benefits will be. I don't know anything about it. After Chrysler made a book and gave a lecture in an interview, the board of directors kicked out of the company. You can go to www.thesuperficial.com to stay awake.

Abstract: we find that the firms of CEOs who achieve "Superstar" status via prestigious nationwide awards from the business press subsequently underperform beyond mere mean reversion, both relative to the overall market and relative to a sample of "hypothetical Award winners" with matching firm and CEO characteristics. at the same time, award-winning CEOs extract significantly more compensation from their company following the award, both in absolute amounts and relative to other top executives in their firm. they also spend significantly more time and effort on public and private activities outside their company such as assuming board seats or writing books. the incidence of earnings management increases significantly after winning awards. our results suggest that media-induced superstar culture leads to behavioral distortions beyond mere mean reversion. we also find that the effects are strongest in firms with weak encrypted ate governance, suggesting that firms cocould prevent the negative consequences.

Abstract: We study real estate purchases by major company CEOs, compiling a database of the principal residences of nearly every top executive in the Standard & Poor's 500 Index. when a CEO buys real estate, future company performance is inversely related to the CEO's liquidation of company shares and options for financing the transaction. we also find that, regardless of the source of finance, future company performance deteriorates when CEOs acquire extremely large or costly mansions and estates. we therefore interpret large home acquisitions as signals of CEO entrenchment. our research also provides useful insights for calibrating utility based models of executive compensation and for understanding patterns of veblenian conspicuous consumption.

Conclusion: My attention is dispersed. My nadd has severe symptoms and no medicine is available.
