When last we checked in on Sergey Aleynikov, the former Goldman Sachs computer programmer convicted of stealing the confidential source code of Goldman's high-speed trading system, prosecutors were debating with his lawyers over his sentence.

Prosecutors were arguing for 10 years, while Aleynikov's lawyer was asking for probation -- no jail time at all.

Well, the sentence came down Friday afternoon -- and the prosecutors, well, won. U.S. District Judge Denise Cote sentenced Aleynikov to more than eight years behind bars.

"I very much regret the foolish decision to download information, part of this information was proprietary to Goldman," Aleynikov said before sentencing. "I never meant to cause Goldman any harm. I did not intend to harm anyone."

However, Judge Cote didn't agree. "He knew that what he was doing would harm Goldman Sachs. There is no other impact," she said. Click here for Chad Bray's story in the WSJ.
