Did you know that a startup powers Gmail’s video chat feature?

?ui=2&view=att&th=124a4d6953fd7fee&attid=0.1&disp=attd&realattid=ii_124a4d6953fd7fee&zwThat's some smacking tech research company - the inheritors of the likes of Xerox and HP.

Google built a web client around Vidyo's system and launched it nearly exactly a year ago. 

Vidyo announced that it has secured a patent for the technology that underlies the telepresence service it provides Google and other customers: "System and Method for a Conference Server Architecture for Low Delay and Distributed Conferencing Applications." 

Vidyo's technology treats every participant in a conference individually so as to give each the best capable up-stream and down-stream experience at any one moment by adjusting bitrates and resolutions dynamically (Google limits its implementation to only two people, but Vidyo can accommodate many more).

How does Shazam Identify Songs?

Shazam, launched in 2002 enables music lovers to identify tunes anywhere - using just their mobile phone. Record the song playing live and send it to Shazam

How Shazam works. 

The company has a library of more than 8 million songs, and it has devised a technique to break down each track into a simple numeric signature—a code that is unique to each track.

How does Shazam make song fingerprints? 

As Avery Wang, Shazam's chief scientist and one of its co-founders, explained to Scientific American in 2003, the company's approach was long considered computationally impractical—there was thought to be too much information in a song to compile a simple signature. But as he wrestled with the problem, Wang had a brilliant idea: What if he ignored nearly everything in a song and focused instead on just a few relatively "intense" moments? Thus Shazam creates a spectrogram for each song in its database—a graph that plots three dimensions of music: frequency vs. amplitude vs. time. The algorithm then picks out just those points that represent the peaks of the graph—notes that contain "higher energy content" than all the other notes around it, as Wang explained in an academic paper he published to describe how Shazam works (PDF). In practice, this seems to work out to aboutthree data points per second per song.

A brief history of PayPal

A University of Illinois graduate moved to Silicon Valley with a great goal (perhaps inspired by the Illini commencement address) – develop security software for hot-selling handheld devices like the Palm Pilot. He assumed that enterprises were soon going to be using Palms as primary means of communication and sharing documents, and would need security to protect business secrets. "Any minute now, there'll be millions of people begging for security on their handheld devices," he thought. He was wrong – he never found a demand for handheld security software.

He could have kept trying to make his original idea work. Entrepreneurs that do stick to fixed goals are very good at least at one thing – wasting investors' money. An idea for an online grocery startup, Webvan, managed to go through $1 billion before finally pulling the plug.

Illinois Man was different. He shifted to Plan B. Sell his cryptography software. Still no takers. We can skip over Plans C, D, and E, which all failed.

Plan F was a system for securely transferring cash from one Palm Pilot to another. He put a demo on the Internet so people could see how great it would be for Palm Pilots. People liked the web demo and started using it for real transactions, while the demand from Palm users still failed to materialize. eBay users started asking if they could put the web demo in their ads for people to pay them. There was no demand for the product, only for the web demo.

Illinois Man finally realized what might succeed. He forgot about Palm Pilots. Plan G was a system for making secure online payments for sites like eBay. His Plan G company was called PayPal, and his name was Max Levchin. eBay eventually bought PayPal for $1.5 billion. The story is from a new book by John Mullins and Randy Komisar, Getting to Plan B.

Why Controlled Markets are bad?

Excerpt from: Dr T J Rodger's (Cypress Co-Founder and President & CEO) testimony to the US Senate

Europe's JESSI showered billions on the European semiconductor industry. It also "rationalized" the industry by allocating certain market segments to various companies. Siemens became the DRAM company for Europe--and has since gone out of the business. Philips became the SRAM company for Europe--and has since gone out of that business.

After inadvertently weakening its chip industry, Europe then established 14% import duties on foreign chips--the next logical step of desperate government policy. The import duty had precisely the effect we might expect: It raised the price of components to the European computer industry and virtually wiped it out as well. Today, there is no European chip industry or computer industry to speak of--thanks to the role of government programs like JESSI. European taxpayers gave up part of their income to wipe out two critical industries! We can't afford to emulate such failed experiments.

How to replicate Silicon Valley model

Source:http://www.paulgraham.com/revolution.html

If you wanted to create a startup hub by reproducing the way existing ones happened, the way to do it would be to establish a first-rate research university in a place so nice that rich people wanted to live there. Then the town would be hospitable to both groups you need: both founders and investors. That's the combination that yielded Silicon Valley. But Silicon Valley didn't have Silicon Valley to compete with. If you tried now to create a startup hub by planting a great university in a nice place, it would have a harder time getting started, because many of the best startups it produced would be sucked away to existing startup hubs.

Read this too: How to be Silicon Valley 


Ideas for Startups!

Nice Article: http://www.paulgraham.com/ideas.html

Excerpt:
The initial idea is just a starting point-- not a blueprint, but a question. It might help if they were expressed that way. Instead of saying that your idea is to make a collaborative, web-based spreadsheet, say: could one make a collaborative, web-based spreadsheet? A few grammatical tweaks, and a woefully incomplete idea becomes a promising question to explore.

There's a real difference, because an assertion provokes objections in a way a question doesn't. If you say: I'm going to build a web-based spreadsheet, then critics-- the most dangerous of which are in your own head-- will immediately reply that you'd be competing with Microsoft, that you couldn't give people the kind of UI they expect, that users wouldn't want to have their data on your servers, and so on.

A question doesn't seem so challenging. It becomes: let's try making a web-based spreadsheet and see how far we get. And everyone knows that if you tried this you'd be able to make something useful. Maybe what you'd end up with wouldn't even be a spreadsheet. Maybe it would be some kind of new spreasheet-like collaboration tool that doesn't even have a name yet. You wouldn't have thought of something like that except by implementing your way toward it.

Treating a startup idea as a question changes what you're looking for. If an idea is a blueprint, it has to be right. But if it's a question, it can be wrong, so long as it's wrong in a way that leads to more ideas.

One valuable way for an idea to be wrong is to be only a partial solution. When someone's working on a problem that seems too big, I always ask: is there some way to bite off some subset of the problem, then gradually expand from there? That will generally work unless you get trapped on a local maximum, like 1980s-style AI, or C.

How twitter was hacked

http://www.techcrunch.com/2009/07/19/the-anatomy-of-the-twitter-attack/

An exciting account of how Twitters strategy documents were unveiled through a targeted hacking attempt. 

The list of services affected either directly, or indirectly, are some of the most popular web applications and services in use today - Gmail, Google Apps, GoDaddy, MobileMe, AT&T, Amazon, Hotmail, Paypal and iTunes . Taken individually, most of these services have reasonable security precautions against intrusion. But there are huge weaknesses when they are looked at together, as an ecosystem. Like dominoes, once one fell (Gmail was the first to go), the others all tumbled as well. The end result was chaos, and raises important questions about how private corporate and personal information is managed and secured in a time when the trend is towards more data, applications and entire user identities being hosted on the web and 'in the cloud'.
