В сентябрьском номере Vanity fair публикуется статья Майкла Льюиса о Сергее Алейникове с его версией происшедшего с ним.
Вот первая часть.
Наивный идеалист, столкнувшийся с реалиями Уолл-Стрита:
Serge quickly discovered, to his surprise, that Goldman had a one-way relationship with open source. They took huge amounts of free software off the Web, but they did not return it after he had modified it, even when his modifications were very slight and of general rather than financial use. “Once I took some open-source components, repackaged them to come up with a component that was not even used at Goldman Sachs,” he says. “It was basically a way to make two computers look like one, so if one went down the other could jump in and perform the task.” He described the pleasure of his innovation this way: “It created something out of chaos. When you create something out of chaos, essentially, you reduce the entropy in the world.” He went to his boss, a fellow named Adam Schlesinger, and asked if he could release it back into open source, as was his inclination. “He said it was now Goldman’s property,” recalls Serge. “He was quite tense. When I mentioned it, it was very close to bonus time. And he didn’t want any disturbances.”
Ну а это можно было ожидать:
One small example of the kind of problems Serge found: Goldman’s trading on the NASDAQ exchange. Goldman owned the lone (unmarked) building directly across the street from NASDAQ in Carteret, New Jersey. The building housed Goldman’s dark pool. When Serge arrived, 40,000 messages per second were flying back and forth between computers inside the two buildings. Proximity, he assumed, must offer Goldman Sachs some advantage—after all, why else buy the only building anywhere near the exchange? But when he looked into it he found that, to cross the street from Goldman to NASDAQ, a signal took five milliseconds, or nearly as much time as it took a signal to travel on the fastest network from Chicago to New York. “The theoretical limit [of sending a signal] from Chicago to New York is something like seven milliseconds,” says Serge. “Everything more than that is the friction caused by man.” The friction could be caused by physical distance—say, if the signal moving across the street in Carteret, New Jersey, traveled in something less direct than a straight line. It could be caused by computer hardware. (The top high-frequency-trading firms chuck out their old gear and buy new stuff every few months.) But it could also be caused by slow, clunky software—and that was Goldman’s problem. Their high-frequency-trading platform was designed, in typical Goldman style, as a centralized hub-and-spoke system. Every signal sent was required to pass through the mother ship in Manhattan before it went back out into the marketplace. “But the latency [the five milliseconds] wasn’t mainly due to the physical distance,” says Serge. “It was because the traffic was going through layers and layers of corporate switching equipment.”
