The Question was: How Can I Stop Facebook Following Me Around the Web?

Not perfect but best efforts include: Firefox + NoScript alt:NoScript + BetterPrivacy alt:BetterPrivacy + RequestPolicy alt:RequestPolicy + HTTPS Everywhere + HTTPS Finder alt:HTTPS Finder

I’ve found AdBlock plus to be totally unnecessary if NoScript and RequestPolicy are setup restrictively.

Others have recommended but I have not used personally: Ghostery alt:Ghostery

A Fiscally Conservative Approach to the Debt Limit

Keith Hennessey explains the most logically consistent approach I’ve seen to the USA’s federal debt limit for fiscal conservatives at the National Review:

A parent gives his irresponsible child a credit card. That child maxes out the card by paying only the first month’s installment of an incredibly expensive annual subscription.

The parent confiscates the credit card to prevent new irresponsible spending. He must still, however, pay the existing credit-card debt. He must also honor the remainder of the contract his child has signed, even if doing so means he must incur more credit-card debt and ask for an increase in his credit-card limit. Unless he is willing to risk bankruptcy or a lawsuit, he must honor the financial obligations his family member incurred.

The parent has control only over new spending commitments, and he must now severely cut back on those. He places his child on a strict allowance and cuts spending throughout the family budget.

Congress must raise the debt limit. Not doing so would eventually lead to defaulting on Treasury bonds, a potentially catastrophic event. Along with that debt limit, Congress should impose a statutory cap on all non-interest spending.

The president and his allies will demand a clean bill or weaker reforms. Republicans should allow them to try to pass such a bill. They should vote no but not filibuster. When it becomes clear that such a bill lacks even the simple majority needed to pass the House and the Senate, Republicans will have a stronger hand in negotiations.

— Keith Hennessey has served as senior White House economic adviser and deputy director of the National Economic Council. He is a research fellow at the Hoover Institution and blogs at KeithHennessey.com.

Of course a government often has the option that many families do not (at least in the short term). A government can increase it’s income by raising taxes. But there is a limit to maximum tax revenue that can be collected over any period of time. It is also likely more efficient to limit tax revenues below that maximum limit. So Hennessey’s argument is also valid for anyone less concerned about the federal budget’s size and the national debt and projected deficits.

Learning is Not Just Memorizing

One particular part of a story about the teaching experience of a graduate student in math at Dartmouth College in the fall of 1996 resonated with me. It articulated something that I had only an intuitive but often a skeptical understanding of; when you learn something as opposed to simply memorizing a pattern or algorithm, you don’t need to study it again to remember what you learned.

Teaching linear Algebra:

…I was lucky enough to talk to some of my students about the experience a few months later. The general consensus was that the material really stuck. Furthermore nobody studied for the final. No joke. As one girl said, “I tried studying because I thought I should, but I gave up after a half-hour because I already knew it all.” That is how I think it should be – if you study properly through the course, then you won’t need to study for the final. Because you’ve already learned it. And you’ll have a leg up on the next course because you still remember the material that everyone else has forgotten.

Sometimes, even a decade after I’ve last thought about an obscure topic, I’ll recall everything I’ve read about it including arcane details and problems I’ve work out and the reasoning that brought me to conclusions.

Unmediated Information

Canadian Economist, Frances Woolley sketched a diagram to estimate the possible value of unmediated information from economists to the general public. That is, why reading an explanation of economic analysis from an Economist is better than reading a journalist’s explanation.

I honestly think that most journalists wouldn’t know what this diagram means. Would they realize that Woolley’s diagram indicates that the average college graduate understands more about economics than an average journalist? (I don’t think so.) Is that a good assumption by Woolley? (I think so.) What does that say about business and economics journalist that are not Economists? (There are probably a lot of bad ones.) What does this imply about economic reports in popular media? (It is probably under reported and often poorly explained or incorrect.)

Don't Play the Lottery

Some sobering numbers about the Powerball lottery (other lotteries are in the same order of magnitude) from Christopher J. Mecklin and Robert G. Donnelly of Murray State University.   ['Powerball, Expected Value, and the Law of (very) Large Numbers' in the Journal of Statistics Education Volume 13, Number 2 (2005)]

...to be at least 95% confident of winning money on the Powerball, even if we are disciplined enough to only play when the expected value is positive and fortunate enough to be the unique winner when we hit the jackpot, we will have to play hundreds of billions of times. This would require hundreds of billions of dollars (which we don’t have) and hundreds of billions of opportunities to play Powerball when the jackpot is high. Even if we buy hundreds or thousands or even millions of tickets when the expectation is positive, we will probably die long before we are ahead. If we lowered the confidence level to 50% or even 10%, we would still expect to need to play 10 to 20 billion times to realize a profit.

Even if we did have hundreds of billions of dollars at our disposal to play Powerball, we probably wouldn’t want to. Risking $200 billion for the chance to win a prize of even $200 million would be proportional to a person with a yearly income of $50,000 risking that entire salary on a game of chance for the opportunity to win a $50 prize.

They go on to show that your opportunities to play with a positive expected value is limited.

Table 5. Minimum Size of Powerball Jackpot Needed for a Positive Expected Value.

 

Number of Players  Minimum Jackpot $
10,000,000 $293,057,107
20,000,000 $305,207,483
30,000,000 $317,679,592
40,000,000 $330,472,332
50,000,000 $343,584,163
60,000,000 $357,013,121
70,000,000 $370,756,823
80,000,000 $384,812,481
90,000,000 $399,176,916
100,000,000 $413,846,569

It is typical for the Powerball lottery to have about 10 to 20 million players for the smaller jackpots (i.e. drawings held after wins) but at least 50 million players when the jackpot has been built up after several successive drawings without a jackpot winner.

The math used in the paper is facinating. It's definitely worth a look.

Limits of Economic Analysis

Uwe E. Reinhardt an economist at Princeton University, who normally focuses on healthcare economics, recently wrote two excellent articles on the limits of economic analysis. He argues that free trade policy is not solely an economic decision.

Seen on Slashdot Today: Time

As seen on Slashdot today:

Our units of temporal measurement, from seconds on up to months, are so complicated, asymmetrical and disjunctive so as to make coherent mental reckoning in time all but impossible. Indeed, had some tyrannical god contrived to enslave our minds to time, to make it all but impossible for us to escape subjection to sodden routines and unpleasant surprises, he could hardly have done better than handing down our present system.

Keith Hennessey on "The President’s budget: whistling past the graveyard"

In his latest post titled “The President’s budget: whistling past the graveyard”, Keith Hennessey criticizes President Obama’s Budget of the United States Government, Fiscal Year 2012 with some bullet points of his “overall qualitative and strategic impressions”. I share his concerns with one minor quibble.

Mr. Hennessey writes:

  • … With his State of the Union address and this budget, President Obama is trying to define a new problem to be solved. He thinks … our government isn’t spending enough on infrastructure, innovation, and education. Suppose you think he’s right (I don’t). Is this problem more urgent than restoring short-term economic growth? Is it more important than addressing unsustainable deficits and a federal government expansion that will leave fewer resources for the private sector? The President apparently thinks it is. I strongly disagree.

Mr. Hennessey gives no credit for the benefits that could accrue from proper spending on infrastructure and education. There is potential for this type of spending to raise our current and longer-run GDP and thus tax revenue to offset some of the deficit that needs to be addressed. I’m in no position to provide any sort of estimate on the potential returns from proper infrastructure and education spending. However, the budget’s focus on investments in infrastructure and education are reasonable. It just doesn’t constitute a complete solution to the short-run aggregate demand slump nor the long-run deficits our economy is facing.

Mr. Hennessey does provide a hypothesis for why a complete solution was not proposed:

  • The President is choosing both a policy path and a campaign strategy. He is betting that having no proposal to address the looming fiscal crisis is better for his reelection prospects than having one.

  • The President has made his strategic choice: we are headed toward a two year fiscal stalemate in a newly balanced Washington.

If true (and I think it quite likely is), I find this approach deplorable. The President’s duty is to serve his country and defend and uphold the constitution. Our current President seems to be choosing to defend his power and serve his own interests first. Much like every other politician I can think of at the moment.

Seen on Slashdot Today (The Incomprehensibility of Law)

0100010001010011 on the incomprehensibility of law:

In some states, the age of consent and child porn statutes have the same age limits.

For instance, a quick read of NV law shows the AOC to be 16. Child porn is defined as sexually explicit blah blah blah involving a person under 16. Federal law makes it a crime with a person under 18, but there may be some state line/interstate commerce nexus that needs to be fulfilled.

I didn’t feel like looking at too many states, but found this same AOC/CP thing with NH-16/16.

Many states forbid distributing/exhibiting obscenity to people under 18, regardless of their AOC/CP statutes.

So, excluding the feds, it’s not a crime to have sex with a 16 year old or film it. But, she can’t watch the tape afterwards. It’s a crime to allow her 16 year old friend to watch the act as it occurs, but not a crime to have her join. Neither of them can smoke a cigarette or have a beer afterwards. If either one were to rob,beat,kill one of their fellow particpants, they would be tried as an adult in every state in the country.
