What if you worked for Madoff
What would you do, if suddenly one day you stumble upon that extra floor in your office building where your company has been faking data all these years to create the appearance of profitability ?
The better question is, I suppose, how do I maintain my personal safety, my professional integrity, and my networth all at the same time?
Personal safety is important because often, your co-workers WILL HURT YOU if they think you are about to expose the company!
Professional integrity is important. This actually will give this whole blog it’s meaning. Because without professional integrity, it’s actually pretty easy to just keep an eye closed.
And finally maintaining networth will make this whole endeavour challenging. Because it’s very easy to just quit and not get the payoff. It is also easy to expose the company and not get any payoff.
So, what can a person do???
For my self, I want to actually start taking lawyer classes to learn the laws governing corporations and fraud. The Ponzi scheme apparently is illegal for reasons in addition to it’s structure: Fraud, Money laundaring, perjury, etc.
Each of these have specific meaning and is associated with actions. So by learning about the punishments for each count of illegality, I would be able to assess my risk and weighing the trade-offs.
For instance, would I be willing to trade 5% chance of 20 years in prison for a payoff of $10,000,000 in 5 years ?
Read that carefully: Ten Million Dollars for an expected prison time of 1 year (expected value)
For most people, the answer is no. But for some people, the answer might be yes…
map reduce is so repigged
okay, so here’s a problem I ran into today. In PigLatin, I needed to calculate the following:
A = group TABLE by (f1,f2,f3);
B = foreach A generate group, SUM(f4), MIN(f5), MAX(f6), (f7 is null)?1:0;
My problem is that for the data that I have (about 100gb) there are actually only about a dozzen combinations of (f1,f2,f3), so the consequence is that the execution crashes with the reducer running out of memory.
The question is, is it possible to make this calculation even with sparse keys?
Jessica!!
I’ve been watching true blood on HBO. One of the movements I think fans can do is to start a blog about Jessica, Bill Compton’s progeny…
Man, every time Bill yelps at her:
“Jessica!!”
and she snickers
“heheeehee”
and I think, damn! I wanna be Bill.
In fact, I like her so much, I wana start a fantasy campaign titled “Jessica for Queen”….. I mean, if the vamp’s are a democracy.
“Jessica!!!”
National Discrimination
I don’t pretend to understand international politics, but when I look at statistics table like the one below from The DHS:
But how do we justify that the ratio of Asian Indian naturalized into the US is somewhere between 1.7 and 1.3 times the number of Chinese from PRC naturalized into the US?
1.7 times is almost twice the number. Consider a simple calculation. suppose that X is the percentage of world’s population that the US would like to have as it’s citizens. Would X * 1.1e9 be less than X * 1.3e9? Instead of being almost twice as much?
What the heck am I missing here? As dutiful citizen of the US, I’d like to point out that we might be making a serious mistake here not sampling fairly from the world’s population!!
Note that the ratio goes the other way. The legal immigration of Chinese Permanent Residents exceeds that of India to the ratio of 1.4 times as much. So why is it that only 40% of PR of Chinese origin choose to become Americans and as much as 77% of Indian origin choose to be come Americans?
Dare I suggest that Chinese are not as competitive? Less adaptive to the Culture of the United States? Too loyal to their indoctrination from Communist upbringing?
What could possibly be the reason why this is happening? Well, perhaps this may shed more light on the subject. The number of newly issued visas by country breaks down as follows:
So, according to this table, the US actually imports 3 times as many Chinese people to work in the US as the number of Indians recruited. However, Indians were more able to bring their relatives into the US by Immediate or family preference Visa’s. So it would appear that Chinese people are being brought over as labor for the American economy and the Indians are just bringing their families over to live.
It seems that China contribute more to the American Economy than India, but India contribute more to the USA by way of culture (Slumdog), population, and of course consumers.
Overall, I think Indians have a better strategy than Chinese. Slaves and Laborers are really not part of the population until they rebel and live up to human level of quality in life. Then they can even begin to be part of the society.
Sigh, the ever suffering Chinese…
Short sales as call and put options
I made an interesting observation with a co-worker today. It would seem that the “short sale” in real estate world can be viewed as a call option for the buyer and a put option for the lender. Short sale takes place when the owner (and eventually seller) does not pay mortgage for 6 months, and bank that loaned him the money to buy this house(the lender) agrees for him to try to sell the house at a price below his loan amount to minimize the bank’s loss (which would have been the entirety of the remaining loan principle minus whatever the house is worth) The missing amount between short sale price and the remaining loan principle is either forgiven or put into a separate payment program which the owner/seller would have to pay over the next few years.
This situation, though somewhat painful for the owner, creates a great investment opportunity to a buyer. The conventional wisdom is that short sales are some percentage below market value of the house. So for instance, if the house that is for short sale is worth $100,000 at market value, then it is likely that the lender will allow me to buy it at $80,000, or $75,000, or even $50,000 depending on the market and the house.
A buyer, may put in an offer at a price slightly higher than 20% discount (after inspecting the house, of course), say 10% below market. This gives him the advantage over all other buyers who will have made offer assuming 20% to 25% mark down.
If all goes well, he will receive an approval from the lender of the short selling owner, typically three months after the offer is accepted by the seller and submitted to the lenders.
At that point. the buyer has the option of continuing with the purchase at 15% discount, or making an offer on a different, and presumably better, house at the same price.
So, by being involved in a short sale, he creates a call option for himself on an opportunity that may or may not be a good deal. But this choice is almost entirely free. (The offer, cost only fees to a realtor).
And often, it is an entirely legitemate reason that bank takes too long or market recovers for buyer to back out of the offer. So it is nearly zero risk and zero cost to the buyer, but the upside is possibly 10% to 20% guaranteed mark-down from market price of a house.
Now, I realize that the lender may be doing the same thing, which is that they are using the offer as a probabilistic put option, which just means that the arbitrage is shared between the buyer and the lender…
This appears to be common practice amongst professional real estate investors and contractors who flip houses. Just today, I saw two houses close within the same week, the short sale being a good 25% larger in square footage, has an additional pool, but identical lot size, right next to each other on the same street (literally xx1 and xx3 on the same side of the street), exactly same age. And the larger home with the pool that is a short sale sold for something like 7% less than the smaller house right next to it. This illustrate an expert use of this technique I describe above.
I of course also suffer from the same situation. What I paid for my house, bought a short sale that closed exactly within a week before my closing next block over(1xx vs. 2xx). And that house has twice the square-footage of my house, same lot, 10 years older than my house.
The only thing that it does put to question is the professional ethics of my realtor, my seller, my financial agent. Only these people knew of my purchase progress, and only they could have informed that short-seller (or that lender) of my purchase price. I am beginning to wonder about the professional integrity of the people in the real estate business in the San Francisco Bay Area….
到底是何方神圣?
America is such a wonderful country. It’s so vibrantly full of life and cultures. Today, somebody blanked my computer screen while I tried to work.
My initial reaction was to search on google
“Jewish Holidays in 2010”
because I know that previously, some people with advanced hacking skills will hack into my computer and blink my screen or screw with things on Jewish holidays so that I stop working and observe it with them.
Nope, nothing Jewish today, next I searched
“Indian Festivals in 2010”
For some reason, my company is gaining Indian population at an alarming rate. Nope, nothing Indian today… And plus we aren’t competing or anything, so it makes no sense for them to mess with my computer.
“Christian Holidays in 2010”
I said to google, and google said “nope”, today is not a Christian holiday either.
WTF, why would somebody be screwing with my computer on a non-holiday? And why did they screw with my computer on their holidays to start with? Is there a deity unknown to me in each of these religions and corresponding cultures that espouse slothery? Is there a god in their religion that says: “Today, you may not work!!”
Man, I feel so ignorant.
Oh, and the Muslims. That’s the people who believe in Islam a religion, as far as we’re taught in America, that is essentially an organized terrorist organization.
Oh, and Koreans, Man! America is so complicated… Has Koreans invented a saint of some kind after their separation from Chinese culture that I don’t know about?
Which of you deities have I offended today that causes my screen to blank every time I’m about to type a command into my console?
what kind of animal sacrifice must I make to appease you? Can I light some fireworks on July 4th? Does that count???
Happy July 4th everybody!!
The Psychology of Giving Fewer Options at Startup
There’s something strange about the Incentive Stock Option system at Startups in America. Suppose the founders want to make employees work harder. It is to his greatest advantage to give his employees as few stock options as possible. This is not to preserve his own stock options or reduce dilution, but to motivate the employees to work harder.
Because typically, bosses at work get somewhere from 100x to 1000x the stocks an employee has. So a founder who is comfortable with a $1Billion IPO means his employees will only get similar level of reward if the company IPO’s at $100Billion or even $1 trillion. So the employee has to aim much higher than the founders.
This may explain why often the executives at companies will make obviously irrational decisions. They already have $10million, why go to the extra leg of getting to $20million?
But the employee has only $100k, getting to $200k is a huge improvement on quality of life.
How Old is Your Computer
I came to an interesting measurement of age of computer today. Suppose we use something simple minded (such as throughput rate of Integer Arithmetics) as measurement of computing power. Let us further suppose that Moore’s law is really followed by the development of computers during it’s entire development since the very first transistor, then we can make a very interesting calculation.
Let T be the total computing power of all humanity today. (This should be estimable based on number of CPU’s Intel and AMD produces each year).
Let O be the origin where the very first transistor was invented, when the total semi-conductor based computing power of humanity is some small number like (1 integer add)/minute.
Fit an exponentially growing curve between the total computing power between time T and O, plot a graph of this curve with time on the X-axis and total computing power of humanity on the Y-axis.
Now, then, to determine the power of your computer (or computing cloud that you own), simply find on the Y-axis the power of your computer and drop down to X. At that point you can claim:
“My computing cloud is equal to all of human computing power as of February of 1981.”
Makes for great PR snippet.
Also, you can use it as a pitch to get more funding:
“Our computer cluster is still in the 1980’s !!”
“But Dad! My laptop is like so 1950!”
Fooled
Okay, I admit it, I’ve been fooled.
So, apparently, Menlo Park, CA, even though it has a street called the “Edison Way” is not the original Menlo Park (NJ) where Edison worked.
