Toshiba’s OLED Smart Watch Knows Who You Are By Your Pulse

It could have been so much better…

NYC Real Estate News via Tigho


LAS VEGAS – Toshiba is showing off at CES a prototype of an OLED smart watch that knows its owner by his or her pulse.

An embedded ECG sensor in the rear of the watch lets it recognize its owner’s unique pulse patterns, and will shut down the watch’s smart functions if an impostor tries to put it on.

Able to connect to both iPhones and Android devices, the watch displays alerts for incoming calls, emails, and calendar events. Its display can be used for navigation, or to display the latest news and weather information.

The watch’s high-resolution OLED display has sensors built-in that optimize for brightness and viewing angle, so you’ll always be able to see what’s o…

WHAT IS BITCOIN?

Cey

Being in the Digital/Internet industry, one cannot escape the term Digital Currency now. It’s the new fad. It’s going to be a long term fad. So, I have to learn a little bit about bitcoin and what’s the fuss about it.

Easy guide about Bitcoin

1. What is Bitcoin?
A digital currency without notes and coins.
A system which allows you to do anonymous currency transactions.
No authority or organization will come to know your money transaction.

2. What is Double Spending?
Everything can be duplicated in the digital world.
All transactions will be shown in public listing to avoid duplication of the digital currency.
No one can copy the currency as it’s validity is checked.
So one one can double spend on the same bitcoin.

3. How in the world public listing is anonymous?
Apparently, you can keep your bitcoins in a digital wallet – which is in your computer or…

Prediction for a future event: “The Spike”

Real Virtual Currency

Lately the Bitcoin price hasn’t been moving much, at least by Bitcoin standards, and has provided a nice respite from the price parroting that we witnessed in the last big run-up. In it’s place has flourished renewed exploration and discussion regarding the technology itself, how it can be incorporated, implemented, and improved.

But don’t think for a minute that Bitcoin is going to plateau long-term around the $100+ mark. Observing the last two years, we can see that Bitcoin has two basic modes: steady-as-she-goes, and have-you-seen-my-beachball-bonkers. From late 2011 until early 2012, Bitcoin would sit still for months at a single price, occasionally ratcheting up or down depending on the news (i.e. “WordPress now accepts Bitcoin,” or “Bitcoin Savings and Trust is a Ponzi Scheme.”) It can do it! The catch is that Bitcoin only likes to chill out when nobody seems to be looking. From February to April of…

Mining Bitcoin

Bong-Bitcoin

There are various hardware choices and methods to use to mine bitcoin. Whatever hardware and method you choose, you’ll either use your CPU or GPU, an FPGA, or the new ASICs. With the current difficulty of 11,187,257.5 (as of 5/15/13), and going up every two weeks, it is getting harder and harder to mine with the first two types of hardware.

For example, a decent CPU today can get 300Khps (Kilohashes per second), while a good GPU can get 500Mhps.

An FPGA might get anywhere from 100-800Mhps and higher, and an ASIC can get 4.5Ghps up to 1.5Thps! See the Mining hardware comparison wiki page for details.

Check the Bitcoin mining profitability calculator to see if your hardware or the hardware you’re looking at getting is worth purchasing, and if the energy use will still make it profitable or not.

Since bitcoins can only be harvested when solving a block…

Strengthening U.S. Securities Via Crypto-Currency Lessons

Bitcoin has received a lot of attention since Satoshi Nakomoto published a paper in 2009 that explained the the potential for currency to be exchanged online without involvement of a financial institution (i.e. a bank). (Checkout: http://bitcoin.org/bitcoin.pdf).

The last four years, however, have seen Bitcoin experienced considerable shifts in the scale of interest and support. They developed a gold-rush-like following, then crashed. The last year of stabilization efforts including a high-profile accumulation by the Winklevii – twins Cameron and Tyler Winklevoss. (Checkout: http://dealbook.nytimes.com/2013/04/11/as-big-investors-emerge-bitcoin-gets-ready-for-its-close-up/).

The currency allows for irreversible transactions, peer-to-peer transactions, double spending prevention through block chaining, and a fixed currency pool of 21 million. Given that the 21 million Bitcoins can themselves be divisible by 8 decimal places (100 million) or 21 x 10^14 units, well, the pool is substantial.

The computing network of Bitcoin has been running for over four years, generating block chains in the hundreds of thousands, facilitating the millions in daily transactions in the tens of thousands (See: http://blockchain.info).

With only one security issue to date (https://en.bitcoin.it/wiki/Incidents#Value_overflow), the hash proof-of-work (https://en.bitcoin.it/wiki/Proof_of_work) expense can scale to the applicable systems or infrastructure. For example, a simpler proof-of-work can be created for fixed private pools of currency. And more expensive proof-of-work can apply for already issued crypto-currencies, for say, U.S. Corporate securities.

Unlike the purely digital crypto-currency, U.S. Securities from corporations are issued by the companies and managed by attorneys, often prone to making errors as there are no requirements for corporate stock ledgers to be managed by any sophisticated software or third party audit system. There is no infrastructure for brokerage houses to handle anything more than corporate seal stocks or electronic ledgers. There is no technical component for the authentication of such security. And the existence of crypto-stocks has yet to be invented. Yet, the private holdings of corporate securities in the U.S. are the center of financial wealth and, as percentages go, the target for the most abuse.

While capitalistic-minded traders and business owners would like to be less regulated, everyone can agree that some agency has to take the role of oversight for wrong-doers. A peer-to-peer network of broker-dealers could be created for the crypto-stock infrastructure. With government oversight as a peer node – processing the block-chains and issuing user IDs could ensure true registered users.

Cryptography and digital certificate management are emerging trends in the corporate governance space, too, spanning from contract workflow and execution, corporate records (including board minutes and shareholder ratification) to the proposed stock issuance and sale. A large next generation infrastructure needs to be created to support this, but the enhancements could be analogous to the digitalization of the Superior Courts and Federal Courts with PACER and ECF.

Microsoft and Yahoo Continue Their Revenue-Per-Search Guarantee Partnership: A Precedent for Cooperation or An Albatross

It’s always interesting when two giants set aside their egos and collaborate on some deal or other. In this case, we have a software giant paying a second-to-Google superpower of search engines. Paying for what, though? Well, something called revenue-per-search or RPS. Or the shortfall that is associated with it.

The best way to understand the situation is to look back a few years, to 2009, when Microsoft and Yahoo first signed a search deal. Per this deal, Microsoft promised that Yahoo would earn a certain amount of money per search. When they didn’t hit the agreed upon RPS targets, Microsoft also agreed to make up the difference. In effect, they have been footing the bill for the last four years. And there are six more years to go, if the agreement is upheld to the end.

Why would Microsoft be in partnership for Yahoo, though, and why would it continue to make quarterly payments for a deal that clearly isn’t delivering the expected results? Other than being caught in a 10-year contract, there’s not much other reason.

Much of the issue has to do with Microsoft’s AdCenter and the technology they have in place for the buying and delivering of online ads. Basically, the system they use to push online ads really isn’t working as well as expected and never has. There’s considerable speculation whether Yahoo might actually go ahead and forge an alliance with Google to go ahead and work out the search engine ad problem. And even more speculation that they are hunting for a get-out-clause.

The real question we should be asking: why would Yahoo continue to partner with Microsoft when the foundation for the cooperation really isn’t there? Not only is Microsoft still falling short on its deal, it is also struggling to come up with much of a solution to improve the investment return.

As far as the partnership aspect goes, I think it is interesting that there is still any effort to keep the deal afloat. Perhaps it’s more that there really hasn’t been much of an effort – at least not an obvious one – to try and improve on Microsoft’s AdCenter.

The world of paid online advertising is certainly very tricky. With all the talk about grassroots campaigning and how people are just completely put off by paid online advertisements anyway, it’s a wonder anyone ever considers paying for advertisements at all. But that should be something, surely, that Microsoft and other invested companies are actually trying to solve. After all, grassroots advertising doesn’t work for everyone and it takes a lot of time.

Still, this partnership between Yahoo and Microsoft really isn’t moving things forward with RPS. Nor is the partnership apparently getting anyone anywhere.

While it is inspiring perhaps to see two major Internet based companies in partnership, (rather than what we have seen, for instance, with Amazon and Apple, at each other’s throats and battling over pittance), there are much better things that could come from these types of partnerships.
