IDG Contributor Network: The network effect on wealth creation

We live in a network-centric world, and network laws are beginning to govern business models and even global economics. When you understand these laws, you begin to understand why we live in a world where new network-centric business models (think Google, Facebook, Amazon, Airbnb, etc.) become de facto monopolies that result in incredible wealth creation.More important, you might be able to figure out how to put these same network effects to work for your business to spur growth and increase customer and shareholder value.Metcalfe’s Law and network effects The first law to understand is Metcalfe’s Law. As you probably know, Bob Metcalfe is the co-inventor of Ethernet. I’ve met Bob a few times in my career. He’s smart, kind and very intuitive. Back in the dawn of networking, he made an observation about how networks work, and he put an equation behind it. That equation has come to be known as Metcalfe’s Law. Here’s how it goes and why it’s critical for modern business models, not just for the networks that underpin them.To read this article in full or to leave a comment, please click here

Second group of hackers found also targeting SWIFT users

A second hacking group is also trying to rob banks by exploiting the SWIFT money transfer system, following a US$81 million heist in February that used a similar approach.The cyberattacks have been going on since January and have been targeting companies in the U.S., Hong Kong, Australia, and other countries, according to a Tuesday report from security firm Symantec.A "rough guess" is that about 100 organizations have been hit so far, based on the 74 individual computer infections detected, the security firm added.As part of their attacks, the hackers used malware to cover up records of fraudulent transactions made over SWIFT, preventing their victims from learning about the money theft.To read this article in full or to leave a comment, please click here

With the Galaxy Note7 dead, here are 7 other Android phablets to consider

Cease FireImage by REUTERS/Edgar SuIt’s official: the Galaxy Note7 is no more. The company already pulled out a miracle with its unprecedented recall to address the phone’s defective battery, only to be scorched again when more units started igniting. Samsung has now stopped production and wants you to (again) power off your device for good.To read this article in full or to leave a comment, please click here

Hardware makers unite to challenge Intel with Gen-Z spec

After years of being offered as separate technologies, storage and memory are beginning to merge. It's already happening, for example, with 3D Xpoint, a technology from Intel and Micron that can serve as memory, storage, or both. Now, a new consortium, called Gen-Z, is out to ease the transition to this new class of storage and memory in computers. It's creating a new specification and architecture that will make it easier to add new forms of non-volatile memory to computers. Gen-Z will have a new connector, fabric and data transfer protocol. One goal is to create an open standard so new forms of memory can communicate with processors and accelerators in a coherent manner. Gen-Z will also work with SSDs like QuantX from Micron.To read this article in full or to leave a comment, please click here

On the ‘net: BGP as an SDN

There are probably a dozen other ways to influence the path in this situation using a route reflector in BGP. Each of these methods have advantages and disadvantages; for instance, flowspec and segment routing can classify traffic based on the source address, or other fields in the packet header, while modifying just the destination will modify the flow for every packet destined to F. But what’s interesting here is not the specific mechanisms used and their limitations, but rather that the RR can be treated as a controller which modifies the base BGP routing information using only mechanisms available within BGP itself. —ECI

Wi-Fi vs. LTE could be the start of a mobile rollercoaster

The long fight over LTE networks sharing frequencies with Wi-Fi may be just the first of many battles as device makers and service providers try to make the most of the limited available spectrum.Around the world, regulators and industry are working on how to let different kinds of networks use the same spectrum. The new techniques and policies they use should lead to better mobile performance in some areas, but it’s also likely that wireless performance will fluctuate more as you move around.LTE-U has grabbed headlines because it involves licensed carriers using some of the channels that consumers depend on for Wi-Fi service, which often is free or runs on users' own routers. Wi-Fi supporters cried foul last year after Qualcomm and some U.S. carriers proposed the technology, and it took until last month for the two sides to reach an apparent peace agreement.To read this article in full or to leave a comment, please click here

IDG Contributor Network: It’s time to encourage diversity in tech freelancing

It’s no secret the tech industry has a diversity problem. Google, Twitter, Facebook, Microsoft, Yahoo, Amazon, Apple and Pinterest are among the companies that have publicly shared how few of their tech positions are filled by women and minorities.This lack of diversity is a big problem for these companies, affecting their innovation and damaging their culture. One study found that companies with racially diverse leadership teams financially outperform their peers by 35 percent. Diversity boosts the bottom line.To read this article in full or to leave a comment, please click here

Encrypted communications could have an undetectable backdoor

Researchers warn that many 1024-bit keys used to secure communications on the internet today might be based on prime numbers that have been intentionally backdoored in an undetectable way.Many public-key cryptography algorithms that are used to secure web, email, VPN, SSH and other types of connections on the internet derive their strength from the mathematical complexity of discrete logarithms -- computing discrete logarithms for groups of large prime numbers cannot be efficiently done using classical methods. This is what makes cracking strong encryption computationally impractical.Most key-generation algorithms rely on prime parameters whose generation is supposed to be verifiably random. However, many parameters have been standardized and are being used in popular crypto algorithms like Diffie-Hellman and DSA without the seeds that were used to generate them ever being published. That makes it impossible to tell whether, for example, the primes were intentionally "backdoored" -- selected to simplify the computation that would normally be required to crack the encryption.To read this article in full or to leave a comment, please click here
