The Future of Journalism in the Internet age: Watchdogs or Lapdogs?
Media watchdogs, increasingly criticized, threatened and attacked by corporate interests and global governments, are also among the prominent victims of falling public trust in the wake of the proliferation of so-called ‘fake’ news.
Despite some self-inflicted problems, such as those highlighted by the Leveson inquiry in the United Kingdom five years ago, news media and responsible journalism remain of critical importance to democracy.
The Internet Society’s 2017 Global Internet Report reveals how media is intricately entwined with society and it will become more so as more people and services go online. The Internet has grown from 400 million users in 2000 to 3.5 billion users today and as access expands further the media have countless new opportunities to increase their reach and better inform their audiences.
But “going online” also introduces unique challenges for the media. In the next five to seven years, the Internet will continue to fundamentally impact society and the media. According to Reporters without Borders, media freedom violations – impacting particularly anonymity, privacy and free expression – have increased by 14 percent in the past five years, for example.
As the Internet and news media become more converged, it is relatively easy to identify Continue reading

Unique IPv6 Prefix Per Host – How Complex Do You Want IPv6 to Be?
In December 2017 IETF published RFC 8273 created by the v6ops working group (which means there must have been significant consensus within the working group that we need the solution and that it makes at least marginal sense).
The RFC specifies a mechanism by which the first-hop router allocates a unique /64 IPv6 prefix for every host attached to a subnet and uses unicast and multicast RA responses sent to unicast MAC addresses to give every host the impression that it’s the sole host on its own subnet.
The first thought of anyone even vaguely familiar with how complex IPv6 already is should be “WTF???” Unfortunately, there are good reasons we need this monstrosity.

Today I am going to talk about another technology named as Multi-Chassis Link Aggregation which is generally used is many of the vendors like Juniper, Arista Networks and so on. Here in this article I am going to have discussion with respect to Arista Networks.
As i said, before i will start with the Multi-Chassis Link Aggregation, I would like to tell you guys that we have our own youtube channel for various network videos that can further help you guys to study further. I will going to add many more videos soon on the channel, Please subscribe to the channel for the study network related videos.

Now the question is what is Multi-Chassis Link Aggregation ?
A multi-chassis link aggregation group (MLAG) is a pair of links that terminate on two cooperating switches and appear as an ordinary link aggregation group (LAG). The cooperating switches are MLAG peer switches and communicate through an interface called a peer link.
While the peer link’s primary purpose is exchanging MLAG control information between peer switches, it also carries data traffic from devices that are attached to only one MLAG peer and Continue reading
Introduction to Multi-chassis EtherChannel(MEC) in Cisco Switches
Today I am going to talk about the technology used in the enterprise or the datacenter environment for various vendors in the market. Starting from the Multi-chassis EtherChannel (MEC), Multi-chassis EtherChannel is generally used in the Cisco technology with the VSS.
Before I start with the Multichassis EtherChannel, I would like to tell you guys that we have our own youtube channel for various network videos that can further help you guys to study further.

Multi-Chassis EtherChannel
Multi-chassis EtherChannel (MEC) is a Layer 2 multipathing technology. This form of EtherChannel allows a connected node to terminate the EtherChannel across the two physical Cisco Catalyst 6500/6800 Series Switches that make up the VSS leading to creating simplified loop-free Layer 2 topology.
Cisco’s Multi-chassis EtherChannel (MCEC) solution addresses the need for inter-chassis redundancy mechanisms, where a carrier wants to “dual home” a device to two upstream points of attachment (PoAs) for redundancy

Terminology Tuesday Presents: Data Gravity
Data Gravity is a concept first coined by Dave McCrory to describe the tendency of data to attract more data, applications and services. As you may have guessed from the name, this principle has many parallels to Newton’s Theory of Universal Gravitation.
The basic premise is that a singular piece of data isn’t meaningful but with more data (metadata as it’s generally called) additional context (and therefore more meaning) can be derived. When all that data is bundled with more applications and services, one can harness a considerable amount of power as evidenced by today’s trends towards data and analytics.
For example, let’s take this piece of data: 0. Although we know what zero means conceptually, we don’t have any way to determine how we should feel about it. Without any context just knowing the number 0 is essentially worthless. If, for instance you were to know the additional data of “inventory of toy Elmos” + [insert where you live] you’d know that you need to make an only order and ASAP.
Data for larger institutions is just like this, except the concept of “friction” plays a larger role. Data Friction Continue reading
Bitcoin: In Crypto We Trust
Tim Wu, who coined "net neutrality", has written an op-ed on the New York Times called "The Bitcoin Boom: In Code We Trust". He is wrong is wrong about "code".The wrong "trust"
Wu builds a big manifesto about how real-world institutions aren't can't be trusted. Certainly, this reflects the rhetoric from a vocal wing of Bitcoin fanatics, but it's not the Bitcoin manifesto.Instead, the word "trust" in the Bitcoin paper is much narrower, referring to how online merchants can't trust credit-cards (for example). When I bought school supplies for my niece when she studied in Canada, the online site wouldn't accept my U.S. credit card. They didn't trust my credit card. However, they trusted my Bitcoin, so I used that payment method instead, and succeeded in the purchase.
Real-world currencies like dollars are tethered to the real-world, which means no single transaction can be trusted, because "they" (the credit-card company, the courts, etc.) may decide to reverse the transaction. The manifesto behind Bitcoin is that a transaction cannot be reversed -- and thus, can always be trusted.
Deliberately confusing the micro-trust in a transaction and macro-trust in banks and governments is a sort of Continue reading
A Guide to Open Source for IT Practitioners
It’s easy to see that open source is changing the way people think about infrastructure. However, as the saying goes: “The future is here, it’s just not evenly distributed”. As is normal, there will always be pockets of IT where active involvement in open source will just take some more time. I’ve worked on open source for a few years now, and I have always wanted to publish a post that focuses on a few key ideas that I wish I could tell every new entrant into the world of open source.A Guide to Open Source for IT Practitioners
