This change is as momentous as the industrial-age shift from craft production to mass manufacture, from individual workers in separate shops turning out finished products step by step to massive factories that break up production into thousands of parts and perform them simultaneously. No single computer could update millions of auctions in real time, as eBay does, and no one machine could track thousands of stock portfolios made up of offerings on all the world’s exchanges, as Yahoo does. And those are, at most, terascale tasks. Page and Brin understood that with clever software, scores of thousands of cheap computers working in parallel could perform petascale tasks – like searching everything Yahoo, eBay, Amazon.com, and anyone else could shovel onto the Net. Google appears to have attained one of the holy grails of computer science: a scalable massively parallel architecture that can readily accommodate diverse software.

Google’s core activity remains Web search. Having built a petascale search machine, though, the question naturally arose: What else could it do? Google’s answer: just about anything. Thus the company’s expanding portfolio of Web services: delivering ads (AdSense, AdWords), maps (Google Maps), videos (Google Video), scheduling (Google Calendar), transactions (Google Checkout), email (Gmail), and productivity software (Writely). The other heavyweights have followed suit.

Unbeknownst to my family and me, someone was scoping out our trash earlier this year — someone hired by Hewlett-Packard Co.

The trash study was carried out in January by Security Outsourcing Solutions Inc., a Needham, Mass., investigative firm that H-P employed, according to a briefing H-P officials gave me yesterday. Whether the sleuths ever encountered my toddler’s dirty diapers, H-P said it doesn’t know.

I learned this — and more — as I sat in a conference room at H-P’s outside law firm yesterday in San Francisco, where attorney John Schultz ran through a litany of snooping tactics H-P’s agents used against me as part of its effort to identify which of its directors might be leaking news to the press. For around a year, Mr. Schultz told me, H-P collected information about me. H-P’s investigators tried at least five times, he said, to get access to my home-phone, cellphone and office-phone records. In several instances, they succeeded: H-P now has lists of calls I made to people such as my editors, my husband, my insurance company and a reporting source employed by one H-P rival.

H-P’s agents had my photo and reviewed videotaped footage of me, said Mr. Schultz, of the law firm of Morgan, Lewis & Bockius. They conducted “surveillance” by looking for me at certain events to see if I would show up to meet an H-P director. (I didn’t.) They also carried out “pre-trash inspections” at my suburban home early this year, Mr. Schultz said.
