Marseille reste la ville la plus embouteillée de France
Lyon se situe en 3e position du classement avec un taux de congestion de 31 %. «Sur un trajet de 30 minutes en conditions de circulation optimales, un conducteur perd en moyenne 39 minutes par jour lorsqu'il effectue ce trajet aller-retour aux heures de pointe du matin et du soir et comme à Paris, la situation s'est détériorée puisque ce temps a augmenté de 3 minutes par rapport à l'an dernier», commentent les auteurs de l'étude.

Draft: From Zero To Kickstarter In $5k | Need/Want
We decided on a hard cover, so you can throw it in your bag without worrying about it. Super thick paper means when you’re writing a note, it never bleeds through to the next page (this would also be important during scanning!). We also made them the exact size of the iPad mini, as a lot of people will probably be carrying these things together anyway.

We needed to work out how we were going to position this. We’d played around with A/B testing headlines on Facebook with Smart Bedding, but it can get pretty expensive if you want a decent-sized pool of data.

Incidentally, if you’re a product person that ever has trouble explaining flows and communicating ideas to designers and engineers, I can’t recommend spending a few hours learning your way around After Effects highly enough. Being able to mock up exactly how you want things to look and work, in a few minutes, is INVALUABLE!

There seems to be a strong correlation between the quality of a Kickstarter video and how much money that project raises. Because of this, we wanted to make sure our video was decent. This was by far our biggest expense.

Dr. Bunsen / Beer Selection
I decided to explore the data to learn what characteristics of beer are associated with the highest review scores and then use this information to pre-screen the number of beers that I needed to manually lookup in BeerBuddy. The goal of this analysis was to learn what features of beer are associated with the highest and lowest reviews so I could make better beer selections and to get in and out of the store faster.

设计更省油的飞机只会加速石油消耗
"The Conundrum" by David OWEN
The Conundrum is a mind-changing manifesto about the environment, efficiency and the real path to sustainability.

Cheap and easy electronic communication has probably helped rather than hindered this. First, connectivity is usually better in cities than in the countryside, because it is more lucrative to build telecoms networks for dense populations than for sparse ones. Second, electronic chatter may reinforce rather than replace the face-to-face kind. In his 2011 book, “Triumph of the City”, Mr Glaeser theorises that this may be an example of what economists call “Jevons’s paradox”. In the 19th century the invention of more efficient steam engines boosted rather than cut the consumption of coal, because they made energy cheaper across the board. In the same way, cheap electronic communication may have made modern economies more “relationship-intensive”, requiring more contact of all kinds.

Enforcing the law may also become easier. Andrew Hudson-Smith, director of the Centre for Advanced Spatial Analysis at University College London, thinks that within five years or so police forces will be able to predict and prevent some crimes by watching Twitter and other social media. The thought may give civil libertarians the creeps, but some Londoners, recalling the part played by instant messaging in last year’s riots in their city, may wish the police already had such foresight.

Americans are exchanging ever more words
print's share of our communication with each other has not been squeezed as dramatically by the rise of the internet as some might think. Radio, on the other hand, has undergone a clear sharp decline. Television, too, accounts for a declining share of American media consumption.

Software reveals the most influential Victorian novelists - tech - 16 August 2012 - New Scientist
THINK of the great 19th-century novelists and names like Dickens, Hardy and the Brontës immediately spring to mind. In terms of influence on other writers, though, the biggest hitters of the era were behind what some call sigh-worthy romance novels and a boyhood adventure yarn.

To Know, But Not Understand
In 1963, Bernard K. Forscher of the Mayo Clinic complained in a now famous letter printed in the prestigious journal Science that scientists were generating too many facts. Titled Chaos in the Brickyard, the letter warned that the new generation of scientists was too busy churning out bricks — facts — without regard to how they go together. Brickmaking, Forscher feared, had become an end in itself. “And so it happened that the land became flooded with bricks. … It became difficult to find the proper bricks for a task because one had to hunt among so many. … It became difficult to complete a useful edifice because, as soon as the foundations were discernible, they were buried under an avalanche of random bricks.”

New scientist: The internet shows the messy truth about knowledge
Our old idea of knowledge shaped itself around the strengths and limitations of its old medium, paper Books and formal papers make knowledge look finite, knowable. By embracing the unfinished, unfinishable forms of the web we are truer to the spirit of enquiry – and to the world we live in The knowledge lived in the loose web of discussion and debate. All this happened faster, wider and deeper than if science had stayed in its paper comfort zone. Even after the question is settled, the knowledge will live not in the final article but in that web of discussion, debate, elucidation and disagreement. It's messy, but messiness is how you scale knowledge.

Twitter Hive Plots
I spend a good deal of time creating and interpreting graph drawings. Visualizing these network representations can be helpful in generating testable hypotheses or as a starting point towards understanding latent features in a data set. The most ubiquitous network representation is probably the force-directed layout. The idea of the algorithm is to use attractive forces of adjacent edges and repulsive forces of other nodes to construct an optimized graph visualization. Below is an example I constructed using my Twitter followers. Nodes represent my followers and edges represent instances where one of my followers follows another one of my followers—mousing over nodes will reveal Twitter usernames:

gnuplot / datafile (3E)
To draw figure of (X,Y) pairs when X data are in 'file1.dat' and Y data are in 'file2.dat' :

gnuplot> plot "< paste file1.dat file2.dat" using 2:4 w lp
You can compare two files with this command. The paste command writes Y data of 'file1.dat' in the second column, and those of 'file2.dat' are in the fourth column, therefore difference between two data sets are expressed by $2-$4, and the ratios are by $2/$4 .

Daytum:数据化自己的人生
然而,怎样的工具才能帮助自己记录这些数据,并转化为图形呢?由信息图天才 Nicholas 和设计师 Ryan Case 一起合作推出的服务 Daytum 能很好的满足人们记录自己各个方面数据的需要,不管是午餐吃了什么,今天做了什么,睡了多长时间的觉,读了多长时间的书或是其它,都可以记录在 Daytum 上面,并转化为图形。

将自己的人生以数据的形式孜孜不倦的记录下来,这样做有什么意义?也许是为了更加深入的了解自己,更好的督促自己,平衡自己生活,也让自己的人生更加圆满。好比喜欢做时间日志的柳比歇夫,一生发布了七十来部学术著作,包括分散分析、生物分类学、昆虫学等方面,这还不包括五百多篇的论文和专著。他之所以能够达到这样的高度,跟他喜欢记录时间日志这个习惯是分不开的。记录时间日志,也是记录人生轨迹。

对于商业来说,记录数据会成为一门生意么?会。比如说豆瓣,一开始不过是一个专门记录人们读过什么书,看过什么电影,听过什么专辑的网站,随后加入书评功能,加入小组,加入小站,变成一种基于兴趣的社交网站。

大学期间,觉得所学的课程中,最有用的一门课就是《文献检索》,至少他教会了学生们怎么自己去获取知识,而不是被灌输无用的“学问”,没有压迫也没有考试,完全自由的获取自己想要的东西。

参考文献著录归法
印刷型文献标识:

M——专著,C——论文集,N——报纸文章,J——期刊文章,D——学位论文,R——研究报告,S——标准,P——专利,Proc. ——会议论文,A——专著,论文集中析出的文献;对于不属于上述的文献类型,采用字母“Z”标识。
