Turbocharging

Don Sherman:

The turbocharger recently turned 100 and the supercharger is even older. And despite their long histories, neither seems a clear winner.

Which is best suited to a vehicle depends on the intended use. With both alternatives at their disposal, engineers consider cost, driving characteristics and the space available under the hood to determine which system belongs where. Even on the same basic engine, the choice may change depending on the vehicle in which it will be used.

Rosanne Cash’s Latest: Black Cadillac

I heard a bit of this new music on LA’s KCRW last week. Rather promising. Alan Light has more:

Relationships between parents and children, between the past and the future, between public and private lives are among the threads running through Ms. Cash’s new album, “Black Cadillac” (which is being released this week on Capitol). Its 12 songs were written between the spring of 2003 and the spring of 2005, a period in which Ms. Cash, now 50, lost three parents: her mother, Vivian Liberto Cash Distin; her stepmother, June Carter Cash; and, in between, her father, Johnny Cash.

General Motors Death Watch

Robert Farago:

It’s increasingly obvious that this necessary (not to say inevitable) “restructuring” will have to wait until GM goes under. The General’s generals made that clear when they reacted to Turnaround King Jerry York’s suggestion that GM should deep-six or sell their Saab and Hummer brands. GM execs dismissed the idea with the PR equivalent of a derisive snort. Marketing Maven Monster Mark LaNeve, a man whose comments about GM’s pricing strategy sound a lot like a snake-handler speaking in tongues, assured the press that “all GM’s brands will eventually be profitable.” Bet your bottom dollar? Done. GM has mortgaged its future on baseless brand optimism.

Harsh. We’ll see how it plays out.

How To Foil Search Engine Snoops

Ryan Singel:

On Thursday, The Mercury News reported that the Justice Department has subpoenaed search-engine records in its defense of the Child Online Protection Act, or COPA. Google, whose corporate credo famously includes the admonishment “Don’t Be Evil,” is fighting the request for a week’s worth of search engine queries. Other search engines have already complied.

The government isn’t asking for search engine users’ identifying data — at least not yet. But for those worried about what companies or federal investigators might do with such records in the future, here’s a primer on how search logs work, and how to avoid being writ large within them.

Google’s data mining tools are not without controversy. Battelle has more here.
