in the basement of Los Angeles and accumulated 1 million Myspace in 24 hoursHis dress is typical of his computer.Focus on peers in coding and technology, not their wardrobes.Today, Kamkar is a professional computer hacker and a highly sought after hacker.After the security advisor, he found major flaws in software from Apple, Google to Microsoft.He also addressed the wardrobe's flaws and now he prefers to design denim and custom shirts instead of a shapeless mix of sweat and unlucky patterns.He also upgraded to a nice car and went to the barber every four weeks."We (technicians) are used to being limited to our little caves because we are all online and we are all programming."But now the internet is easier to access and it's easy to pick up your laptop and go to the cafe, which makes people want to put on some pretty clothes," he said ."."You don't necessarily want to dress like a geek or a lazy guy in public."The cafe owner said they noticed the recent upgrade of the wardrobe 2.0.In trendy cafes, young people work on laptops and iPads and dress up as if they were in a grocery store."The people who come here are very young and attractive....It seems to be a very

Tech, said she noticed that there are two types of technicians in the coffee shop: "People either have meetings, work, or blogI would wear better if I went to the cafe for a meeting.If I'm just sitting there and blogging, then I'm definitely not going to look messy."Many theories abound about what lies behind better clues.Some say that as tech offices become more fashionable, architectural styles are becoming more unique and uncomfortable to dress.Others said that the increase in the number of women joining this line helped to raise the standard of clothing.People pay more and more

1900, you will find people who are trying Radio and Electronics, a group of amateurs and people who are not part of established companies on the East Coast, so they do things in the workshop and in the garage and don't need to dress up.Vance pointed out that HewlettPackard is one of the garages in Palo Altobred companies.Even in their 90 sCom boom, it's still "not how you look, it's what you do."Now, as the tech industry matures, Vance claims that product design and overall aesthetics play a more important role in small start-ups and big companies."Now, young children have got these already very good tools from the past generation, and this is about how to manipulate them and how to polish them."Also, these onceInvisible innovators are now meeting with customers and pitching

startup launchck, explains that part of the reason for having a successful tech company is good design."When people are part of a powerful technology company with a strong brand, the brand ultimately reflects who they are.Detwiler says their dress code is part of the brand and the company needs "more style and beauty for people "."Another well-Well known computer hackers, who are reluctant to be

Jobs, who rarely deviates from his black sundressCroix high collar shirt and 501 Levi's jeans.He was inspired by Sony's staff uniform to implement a uniform dress code at Apple, but the staff flatly rejected the idea.Marissa Mayer, Yahoo's newly appointed president, is often considered the best --Dressed in Silicon Valley costumes, you love designers like Oscar de la lunta and Carolina
