Comparing Bit Torrent Downloaders

I personally like UTorrent on Windows and KTorrent on Linux.

While no experts on this, anything that gets the data down faster while maximizing my pipes efficiency.

I also like Torrenting than  any of the sudo-apt get method of downloading software or the zip unzip,tar untar, install/make file

Torrenting is a simpler way of sharing applications but sadly not used much by the stats computing community to share downloads.

Also I think any dashboard or visualization should be sorted (but not alphabetically but numerically/categorically)

SORT THE DASHBOARD —-KEEP IT SORTED

So I am partially recreating after sorting the data viz from http://en.wikipedia.org/wiki/Comparison_of_BitTorrent_clients

Meet Google’s new CEO

Larry Page
Co-Founder and President, Products

Larry Page was Google’s founding CEO and grew the company to more than 200 employees and profitability before moving into his role as president of products in April 2001. He continues to share responsibility for Google’s day-to-day operations with Eric Schmidt and Sergey Brin.

The son of Michigan State University computer science professor Dr. Carl Victor Page, Larry’s love of computers began at age six. While following in his father’s footsteps in academics, he became an honors graduate from the University of Michigan, where he earned a bachelor’s degree in engineering, with a concentration on computer engineering. During his time in Ann Arbor, Larry built an inkjet printer out of Lego™ bricks.

While in the Ph.D. program in computer science at Stanford University, Larry met Sergey Brin, and together they developed and ran Google, which began operating in 1998. Larry went on leave from Stanford after earning his master’s degree.

In 2002, Larry was named a World Economic Forum Global Leader for Tomorrow. He is a member of the National Advisory Committee (NAC) of the University of Michigan College of Engineering, and together with co-founder Sergey Brin, Larry was honored with the Marconi Prize in 2004. He is a trustee on the board of the X PRIZE, and was elected to the National Academy of Engineering in 2004.

and no coincidence but it reminded me of the Metallica video- Turn the Page. Forgive the Pun, herr Eric

Mapping Health Statistics at CDC.gov

CDC.gov has a great tool for showing United States statistics on death and injury, drillable by various details.

The tool is hosted at http://wisqars.cdc.gov:8080/cdcMapFramework/

As a test I decided to map out injuries due to fire arms , and compare firearm deaths of white people versus the whole population.(see firearm deaths file)

See white people are more likely than black people to own guns (also read http://www.ncbi.nlm.nih.gov/pubmed/9572612 ), but it seems statistically they are less likely to be injured by firearms- so it could affect support for gun control laws on a racial ground- that was my null hypothesis. No politics, just plain statistics. I dont know- why dont you look at the data and decide-

 

 

 

 

 

Stuxnet DeMystified

Detail of a New York Times Advertisement - 1895

A fascinating article in New York Times details the fascinating details of the Stuxnet virus, apparently the most successful cyber weapon in recent times.

Given that Industrial Controllers are a part of a everything from factories to missile launch configurations, I believe this is a fascinating area of study for the world’s research scientists including creating variants and defenses for this.

Checks in the mail more effective checks to your pay

Paycheck (film)
Image via Wikipedia

NBER (whose excellent monthly newsletter I subscribe to- among others) http://www.nber.org/ in a recent paper claims that cheque in mails (one time) sare better spent than monthly pay increases.

I wonder what this conclusion can be used for in designing annual bonuses versus higher pay in private sector compensation- but people do seem happier receiving a bigger one time boost than 12 small mini boosts.

NBER Working Paper No. 16246
Issued in July 2010
NBER Program(s):   EFG ME PE

An NBER digest for this paper is available.

Recent fiscal policies have aimed to stimulate household spending. In 2008, most households received one-time economic stimulus payments. In 2009, most working households received the Making Work Pay tax credit in the form of reduced withholding; other households, mainly retirees, received one-time payments. This paper quantifies the spending response to these different policies and examines whether the spending response differed according to whether the stimulus was delivered as a one-time payment or as a flow of payments in the form of reduced withholding. Based on responses from a representative sample of households in the Thomson Reuters/University of Michigan Surveys of Consumers, the paper finds that the reduction in withholding led to a substantially lower rate of spending than the one-time payments. Specifically, 25 percent of households reported that the one-time economic stimulus payment in 2008 led them to mostly increase their spending while only 13 percent reported that the extra pay from the lower withholding in 2009 led them to mostly increase their spending. The paper uses several approaches to isolate the effect of the delivery mechanism from the changing aggregate and individual conditions. Responses to a hypothetical stimulus in 2009, examination of “free responses” concerning differing responses to the policies, and regression analysis controlling for individual economic conditions and demographics all support the primary importance of the income delivery mechanism in determining the spending response to the policies.
