The Heartbleed bug is a massive security flaw that could put you and your personal information at risk. And while there are things you can do to limit the damage and protect yourself, you haven’t yet seen the ramifications of this security disaster. The Internet in the post-Heartbleed world won’t look like anything you’ve seen before.
Politicians talk about the uninsured. Special interests argue on behalf of those with pre-existing conditions. But why is no one wondering how doctors are affected by the new law? They’re the ones on the frontlines dealing directly with new patients, as well as the red tape that makes bureaucracies go round.
Politicians proclaim the benefits of small business while on the campaign trail. But when they meet in the seedy halls of Congress, they have no problem doing whatever they can to stifle, regulate, and subdue their progress. Instead of siding with entrepreneurs, these politicians often side with political allies and cronies that helped put them into office.
Just because you’re retired doesn’t mean you have to stop working. Especially now that you have all the time in the world to do what you really want. Entrepreneurs don’t only come out of Silicon Valley. They come from all walks of life, from all different ages. If you’re retired and want to stay active while you relax, then find out the steps you need to take in order to start, manage, and grow your next small business.
Technology brought the world together. But has it gone too far? Decades ago, mail was delivered by hand. Now it’s delivered in seconds. How has that changed the way you live your life? How has it changed the way people act with each other? These are just some of the questions we need to ask.
The U.S. dollar has been the world's reserve currency for almost a century, and already there are signs it may be in decline. But that doesn't mean it's not still valuable. On the contrary... As Chris Mayer explains, there are many reasons the U.S. dollar will remain relevant on the world stage for years to come. Read on...
The best way to explain how to choose a good password is to explain how they're broken.
Can you imagine losing $119 billion in a single day? That might sound like an impossible amount of money to lose in any amount of time, but in the high-stakes world of startups, it really can happen in a day. And whenever there’s a “loser” in a zero-sum situation like this, there’s also a “winner.” The difference between the two? Vision.
This technology is not simply for modeling and prototyping, either. TV personality Jay Leno uses a 3-D printer to make custom and hard-to-find parts from scratch for his collection of classic cars. Entrepreneurs have been using these printers in a myriad of ways, and the trend is speeding up.
“It is difficult to make predictions, especially about the future,” says a proverb often attributed to Yogi Berra. Imagine the world of freedom, or lack of it. Who could foresee the technologies that make our lives so rewarding and convenient? The same technologies have us all under the government’s giant microscope. Thankfully, the brave have turned the microscope around.
In the months since Edward Snowden revealed the nature and extent of the spying that the National Security Agency (NSA) has been perpetrating upon Americans and foreigners, some of the NSA's most troublesome behavior has not been a part of the public debate.
The problem for NSA apologist is that when guys like Snowden disclose that the government conducts comprehensive surveillance in ways that would have made 1984’s O’Brien drool, it puts the entire progressive agenda in jeopardy.

The faces of the Detroit bankruptcy are the thousands of pensioners whose promised benefits are suddenly part of the restructure negotiation. When Motown filed for Chapter 9 last July, the city had $11.5 billion in unsecured liabilities.

The New York Times published an interminable article on health care recently. Plenty of facts — how scrupulous are these journalists! — but the article displayed absolutely no comprehension of the basics of cause and effect. I was left wondering about the whole point.The article details how the health care system rewards specialists to an […]
We’ve pointed out in the past that President Obama’s views on the surveillance state shifted completely from when he was Senator to when he was President. As Senator, he supported a bunch of reforms that are very much like the ones his panel have suggested — and which he’s about to ignore. The NY Times […]
Bitcoins are largely considered digital currency (or “crypto currency”) so you’d expect it to be treated like currency on a retail web site. But the Internal Revenue Service might not think so.
The great inventors/businessmen of the First Industrial Revolution, such as James Watt and Matthew Boulton of steam-engine fame, were not just smart but privileged. Most were either born into the ruling class or lucky enough to be apprenticed to one of the elite. For most of history since then, entrepreneurship has meant either setting up […]
Both research and production look poised for a revolution as 3-D printing applies its high-tech charms to the business of creating chemical compounds and turns the production of medicine into a DIY project.
“Tea. Earl Grey. Hot.”When Capt. Jean-Luc Picard wants a steaming beverage in his ready room aboard the starship Enterprise, he just utters those words. The ship’s “replicator” then assembles the necessary atoms — including those for the cup — and produces it, ready for the drinking. Picard thinks nothing of it — it’s hardly more […]
The market has selected different things as money throughout history. Some of these items have served as money in isolated places for specific periods of time — for instance, cigarettes in prisoner-of-war camps. Cigarettes continue to be a currency in prisons if allowed, but if not, according to Wikipedia, “postage stamps have become a more […]

Last year was quite the year for Bitcoin. We’ve seen exponential growth in Bitcoin’s exchange rate and extensive coverage in the media. Another phenomenon we have witnessed is the proliferation of alternative cryptocurrencies, five of which we’ve provided below.
What all of these cryptocurrencies have in common is that they rely on a decentralized network to keep track of transactions. Their scarcity and security is based on cryptography.
Note: All figures from coinmarketcap.com.
[Ed. Note: We should add that this article is from a month ago, so many of the current prices of these digital currencies, as well as their market capitalization, have probably changed.]
Market Capitalization: $600 million
Of all the competing cryptocurrencies, Litecoin is the most similar to Bitcoin. It has been thought of as silver to Bitcoin’s gold, or MasterCard to Bitcoin’s Visa. It has also managed to gain the second-highest market capitalization amongst digital currencies.
One key difference includes a different hashing algorithm designed so that mining Litecoins won’t result in a similar hardware arms race to the one Bitcoin is currently involved in. Litecoin mining these days involves rigs of video cards, or GPUs. It’s similar to how Bitcoin mining was a few years ago, until its ASICs (application-specific integrated circuits) were designed from the ground up to mine Bitcoins.
Litecoins also feature faster confirmation times due to shorter and faster block rewards. It’s scheduled to produce 84 million Litecoins, four times as much as Bitcoin’s 21 million.
Market Capitalization: $131 million
Peercoin’s distinguishing feature is that is uses a method called proof of stake as part of its mining, or as Peercoiners often like to say, “minting.” Proof-of-stake rewards minters for the Peercoins they hold over time.
This is measured in “coin days,” one coin day being equivalent to holding one coin for one day. It’s similar to how a kilowatt hour is defined as using a kilowatt over the course of one hour. So the more coins you hold over a longer time, the more Peercoins you receive through minting.
This is in contrast to most cryptocurrencies’ proof-of-work mining, which rewards miners based on how much computing power they contribute to the keeping track of transactions. Peercoin also uses proof-of-work mining in conjunction with proof-of-work minting, although Peercoin is programmed to eventually rely only on proof-of-work mining.
The maximum limit for the number of these coins is 2 billion. This is so much higher than Bitcoin’s 21 million that it encourages inflationary pressure, which counterbalances the deflationary pressure caused by everyone trying to mint Peercoins and holding onto them.
Price: 4.1 cents
Market Capitalization: $40 million
Nxt is most similar to Peercoin in that is utilizes proof of stake to generate more coins. But unlike Peercoin, it uses proof of stake exclusively.
The only way to get more Nxt coins is to hold them or exchange them in a process dubbed “forging,” in contrast to Bitcoin mining and Peercoin minting. This has a “green” appeal in that it requires no massive, power-consuming hardware rigs, just a small program that will run on pretty much any modern computer.
This also has the practical appeal of not requiring users to invest in the extra hardware and electricity. Instead, you merely exchange something for your initial Nxt coins. Nxt’s developers also pride themselves on having written the Nxt code from scratch, while most alternative cryptocurrencies were developed from using Bitcoin’s code as a basis.
Market Capitalization: $52 million
Namecoin is similar to other cryptocurrencies, but with the additional feature of being a way to register domain names. Instead of .com or .net, Namecoin domain names have the .bit extension. Any method of registering and controlling a domain name is called a domain name system, or DNS.
The current method of domain name registration is regulated by a nonprofit organization called the Internet Corporation for Assigned Names and Numbers, or ICANN. Because ICANN is a centralized organization, it ultimately has power over domain names and can shut down websites for political or other reasons. But because Namecoin is a decentralized network, no one is in control of it.
Just like Bitcoin is a decentralized network that takes the power away from banks and other financial institutions, Namecoin is a decentralized network that takes the power away from ICANN or any other centralized DNS organization. Namecoin is also traded for its own sake, just like Bitcoin.
It’s just like any other cryptocurrency but with the added feature of a decentralized DNS system, which amounts to more “intrinsic value,” which everyone is looking for.
Price: 0.045 cents
Market Capitalization: $11 million
Dogecoin is a cryptocurrency inspired by the “Doge” Internet meme.
Compared with the other cryptocurrencies, Doge is most similar to Litecoin. It uses scrypt, the same cryptographic function as Litecoin. A total of 100 billion Dogecoins will ever be mined, which is even more than Peercoin. Yet because the block reward is so large and frequent (every minute), Dogecoin miners have already mined almost 25 billion Dogecoins, almost 25% of the total.
While Doge gets my vote for the best Internet meme of 2013, you would think that a cryptocurrency wouldn’t manage to go far based on novelty. Yet Dogecoin’s market capitalization is almost $7 million. Wow.
