  1. Why concerned about only one side of Keystone XL? on Google and Facebook: Unelected Superpowers? · · Score: 2

    Interesting that the OP is so deeply concerned with tech companies' lobbying against Keystone XL, but not concerned with the Koch brothers, whose organizations have spent a nine-digit amount of dollars on campaigns and advertisements (often misleading or just plain false) to influence campaigns, with an eye toward issues of interest to the Koch brothers themselves, like getting limits on campaign donations removed and, just to pick a random example, getting the Keystone XL pipeline approved.

  2. Ridiculous on The Math Formula That Lead To the Financial Crash · · Score: 1

    It's ridiculous to blame the Black-Scholes model, the Black-Scholes equation, or the Black-Scholes formulas. There are two groups of individuals responsible for the crash, even if the corporate press refuses to acknowledge it: bank executives who knowingly did ridiculously risky things and the ratings agencies that gave them the cover to do it. It's also ridiculous to refer to the crash as the "subprime crisis," because the problem most definitely was not subprime mortgages. The sum total of all the subprime mortgages was on the order of a few hundred million dollars, but the damage done by the crash was in the tens of trillions of dollars. The bailout of 2008 amounted to over one-and-a-half trrillion dollars, which was enough to pay off all the subprime mortgages several times over, and yet it didn't solve the problem.

    Let's start with the ratings agencies. With winks and nudges to their friends running the banks, the people at the ratings agencies gave ratings of AAA, which means "as close to risk-free as you can get," to packages of mortgages in which they knew many were "subprime" and many, many more had been given by unethical lenders (who later sold them off in packages) who did not check the ability of their customers to pay. In some cases, the AAA rating was even extended to complex derivatives based on the mortgage packages, despite the fact that the people at the ratings agencies didn't understand those derivatives well enough to give a rating at all. It's worth mentioning that among those customers were many middle-class and wealthy individuals counting on the obviously unsustainable growth of real estate prices in the US market so they could take out mortgages to buy properties, hold on to them for 6-18 months, and then "flip" them for a huge profit. Also among them were many companies. So don't go blaming the lower-middle-class and poor holders of "subprime" mortgages, who only represented a small fraction of the number of bad mortgages. Anyway, a rating like AAA should only be given to things that are as risk-free as a government bond. Since wealthy people and economists love to talk about there being "no such thing as a free lunch," it's worth pointing out that that idea is a basic principle used in things like pricing assets. In that context, it's called the "no-arbitrage principle." Arbitrage basically means "risk-free profit." The idea behind the no-arbitrage principle is that if there were an opportunity for risk-free profit, somebody would have already taken advantage of it and driven prices to the point where the opportunity no longer existed. In today's world of high-frequency trading, the no-arbitrage principle actually works pretty well. A classic example of arbitrage would be a stock that's sold in two different exchanges. If the price is lower in one and you can buy it quickly enough, then sell it quickly enough in the other exchange, where it's worth more, then you can make a profit with basically no risk. The thing is that if anyone notices and tries to do that, it drives up the price (buy increasing demand) in the exchange where the price was lower and brings the price down (by increasing supply) in the exchange where the price was higher. The prices are thus driven rapidly toward equilibrium. And in fact a crucial step in the derivation of the Black-Scholes equation is an application of the no-arbitrage principle, equating a risk-free return to the rate paid by government bonds.

    Additionally, when heads had to roll at the banks for, y'know, breaking the world economy, you know the execs wanted to protect themselves and their own and put all the blame on their quantitative analysts, but they couldn't because the quants had done a good job of covering their own asses by sending e-mails to their superiors warning that there were all kinds of risks not being controlled or managed, and that there were even new risks introduced by modeling that could lead to problems. So the execs were fully aware that they were trading in assets tha

At the first company meeting after I got there, I tried to get an idea of what were the highest priorities among the tasks facing the company at that point, not necessarily in order, but just putting a priority from "1" to "3" (I had originally suggested 1 to 5) on each item. Out of 20-odd items, one got a "2" and the rest were "1." I tried to explain that I understood that everything was important and urgent, but that in order to get anywhere, we'd have to give some things higher priorities than others. I explained that "3" didn't mean "unimportant," just "less of a priority than a 1 or a 2."

I called Bank of Brazil's internet banking support, and they asked me to make sure I had the latest "version" of Java installed. I thought that couldn't be the problem, but I did check and it turned out I was an update behind (i.e., I was using version 6, update 17, and the latest was version 6, update 18). I didn't think that could cause the problem, but I figured that in order to continue with B of B's internet banking support, I'd have to be able to say that yes, I had the latest "version" of Java installed.

    As for ATMs, I can tell you that at least some, and possibly all, of the ATMs at the Vila Leopoldina branch of the Bank of Brazil in São Paulo are Linux-based. I actually noticed that around Christmas of 2009. But that's not really relevant to my earlier post. I was talking about desktops.

    By the way, I've had to deal with the following banks in Brazil: BBVA, Bradesco, Itaú, Santander, Unibanco (now part of Itaú, but it wasn't then), and Bank of Brazil. People like to speak ill of government employees, but the best service I've gotten, and not by a little, has been at B of B. Oddly enough, my experience with Bradesco was relatively positive too. Itaú is ridiculously expensive and has piss-poor service, but Unibanco must be the worst bank in the world. They make everything harder than every other bank does, but without adding any additional value. I could deal with, for example, additional security measures that made things a slightly bigger pain in the ass, but Unibanco just gives you the pain in the ass without any benefits. And even though I explicitly asked three times on the day I was opening the accounts at Unibanco and was told that the internet banking was compatible with non-Windows operating systems (important since my life has been completely Microsoft-free for a couple of years now), I didn't find out that Unibanco's internet banking only worked with "Ruimdows" until after I had wasted a lot of time and effort setting up the accounts and then trying to get the internet banking to work (which, by the way, even under ideal conditions and using Windows, would require at least three visits to the branch, which I find ridiculous). With all the passwords Unibanco gave me to memorize, the only way I could possibly keep everything straight was to have the passwords written down somewhere. I found creative ways to hide my passwords in my cell phone's address book, but all the stupid passwords not only didn't add security, they made it impossible to use the bank without writing down passwords somewhere, which is terrible.

    Why is the Linux migration project in Munich so prominent, as mentioned in TFS? I know of much larger migrations, both in terms of the number of computers and the geographic area covered. The Brazilian government has been migrating to Free Software in mass. The Bank of Brazil, for example, has over 100,000 computers running Firefox and BrOffice. As of last June, the estimate was right at 100,000, with 65,000 of those machines running Linux and 35,000 running other operating systems. The Bank of Brazil has branches and offices all over Brazil, which is a very large country. The mass migration happened in 2006, before the migration really began in Munich. The number of machines involved (counting the Linux boxes only) is about 5 times as large as the number of machines to be involved in Munich, and instead of being located in a single city, they are spread out all over a country that's larger than the US would be if it didn't have Alaska, but smaller than the US with Alaska (i.e., larger in area than the "lower 48" plus DC plus Hawaii). In the year 2006 alone, the Bank of Brazil estimated that it saved R$20MM by using Free Software.

    Great. Maybe now the dumbasses at NBC will take their stuff off Hulu, so I can watch it from outside the US, I always thought the US networks should make their shows available vie internet and sell targeted advertising embedded in the same video stream as the shows. Obviously ads for car dealerships in the US wouldn't be interesting to people in other countries, nor would those dealerships be all that interested in getting access to my eyes in a foreign country, but through the magic of teh intarwebz, the US TV networks could sell advertising to advertisers who might ONLY have interest in access to eyes in specific foreign countries. I figured that just like I see ads in Portuguese on web sites I visit in the US (when I allow ads, of course) from IP addresses here in Brazil, ABC could embed video ads from advertisers with somethng to sell in the Brazilian market. There could also be standard web ads.

    I should make some snide remark here about how there's no great loss from not seeing NBC shows since I quit Heroes during the second season (I was horribly disappointed with the final ep of the first season, which felt like it was thrown together at the last minute when they suddenly realized they only had one ep to wrap up the season after building things up really nicely for the first 21 eps), Saturday Night Live went from a normal bad phase to unwatchably unfunny while Tina Fey was head writer (I still haven't decided if she is funny or not, largely because SNL blew diseased goats when she was head writer), and the sometimes-funny Conan O'Brien has been exiled to bring the almost-always-unfunny bloated chin back to The Tonight Show, but there appear to have actually been a couple of funny moments on SNL just this last week. Too bad I wouldn't be able to find out without downloading a pirated copy of the ep.

I'm sure there are people in many other countries in situations similar to mine, and with similar interest in the show. That looks to me like a great opportunity for ABC to make some money selling video ads and regular web ads to advertisers who might be interested in people in other markets who want to watch the final season of Lost before it shows up on their local TV stations. I watched the penultimate episode of the first season of Heroes on the web at my sister's house in the US the day before watching the final episode on TV there. I didn't mind the ads that were in the video with the episode content, because it was actually less trouble to watch via web with ads than it would have been to set up a filesharing program and download the episode without ads. Most of the ads I saw or heard (while doing other things in the room during the ads) weren't all that relevant to me, but then again, I was watching from a computer at an IP address in South Carolina, not Brazil. Now it occurs to me that there's another massive marketing opportunity: I would gladly fill out a form with my name and home address in exchange for being able to watch the eps free via web and without having to resort to piracy. That would allow ABC, for example, to know something about avid viewers of its programs all over the world, which could help a lot with selling ads to a much wider range of advertisers.
