Seymour took a more direct approach: He got those "tech cathedrals" to provide the training and resources for Code Tenderloin, a combination coding boot camp and job-coaching service he founded last year. Cornell Doss, 49, lost his job as a security guard last year, just before Christmas. Without a paycheck, he'd sometimes skip meals to make sure his 12-year-old daughter had enough to eat. In February, he signed up for Code Tenderloin's four-week interview course, meeting for three hours, twice a week. Think of it as intensive job coaching taught by people in the tech industry, such as GitHub, LinkedIn, NerdWallet and Dolby, often from their offices.

Doss learned everything from building an effective resume to how to carry himself in an interview (sit straight, make eye contact, don't cross arms) and questions he should ask, He also practiced in mock interviews and even shadowed the trainers during their day jobs, "They were real, real specific, even to the point of being early for the interview, doing your homework and research on the company, and how to market yourself," says Doss, "I knew some of the resume tricks, but [everything else] was seattle white map iphone case all new to me."Still, it's one thing to land a job -- another to be qualified for something that pays enough to live on, In San Francisco, that usually means knowing how to program, That's why Code Tenderloin also offers Code Ramp, a five-week, 60-hour course -- again taught by experts from local tech companies -- on website development..

"I took this class to become independent," says Hector Calderon, 54, who previously spent 11 months living on the street with his two boys. "[It's] another item to have when you apply for a job and, hopefully, make good money."Project Homeless Connect quite literally brings together every service a homeless or low-income family could conceivably need. Five times a year, PHC holds all-in-one help days where more than 150 nonprofits and city agencies meet under one roof. It's a one-stop center for haircuts, medical and dental care, eyeglasses, wheelchair repair and employment counseling. There are also daily events for services like vision exams, dentures and clothing.

People walk by an ad for upscale apartments in San Francisco's Mid-Market neighborhood, which have been designed to appeal to tech professionals working nearby, PHC gives each person it serves a bar seattle white map iphone case code on a bracelet, then scans that code whenever someone, say, picks up a week's worth of food or comes in for dental care, The information helps PHC stay ahead of demand, Everyone who walks through PHC's doors gets a 3G smartphone, provided by donors like Assurance Wireless, a lifeline assistance program from Virgin Mobile USA, or by Google, which provides Nexus phones, Carriers have donated minutes for those phones..

There are so many homeless in San Francisco, people living there see them as just another part of the landscape, like the dozens of buildings that bear the names of tech giants. Tech is the engine driving San Francisco's wealth; now, it could help the city's least fortunate. "If you can't be seen, technology at least allows you to be heard," says Zordel. "You'll never be part of the conversation without it."Samantha Rhodes (@samanthakrhodes) is a Washington, D.C.-based reporter who's covered tech, politics, culture and local news.
