What Social Media Theorists Say About The Impact of the Internet on our Relationships

Social media was completely unheard of two decades ago, but today it is an integral part of most people’s lives. Social media theorists have different opinions on how the internet affects our relationships. Some of these social media theorists claim that the internet has improved relationships while other theorists claim that that the internet has a negative effect on real world relationships.

The truth is that the theorists on both sides of the question are right. Here’s why.

How Social Media and the Internet Can Aid Relationships

Social media and the internet have the ability to aid relationships in the following ways. It helps family members and friends stay in touch, even when there is a huge gap in distance and time between them. Even for those people who live a busy life, staying in touch through emails and texts is a quick way to let those people you care about know that you are thinking of them, while connecting through social media means that you have a means of keeping up on what is going on in their life. While it may not be ideal, it is a way for people to be able to hold onto the bonds Continue reading

Virtual Data Centers, SDN, and Multitenancy

When you aren’t the size of Netflix, you may not be guaranteed dedicated infrastructure within a data center; you have to share. Even in larger organizations, multitenancy may be required to solve regulatory compliance issues. So what is multitenancy, how does it differ from other forms of resource division, and what role do networks play?

Gartner Inc. defines multitenancy as “a reference to the mode of operation of software where multiple independent instances of one or multiple applications operate in a shared environment. The instances (tenants) are logically isolated, but physically integrated.” This is basically a fancy way of saying “cutting up IT infrastructure so that more than one user/department/organization/and so on can share the same physical IT infrastructure, without being able to see one another’s data.”

That “without being able to see one another’s data” is the critical bit. Allowing multiple users to use a single computer has been possible for decades. Multi-user operating systems, for example, can allow multiple users to log in to a single computer at the same time. While this approach does allow multiple users to share a physical piece of IT infrastructure, it isn’t multitenancy.

In a multi-user OS, the multiple users Continue reading

Truth Matters: Why Journalists Need Encryption Now More Than Ever

As COVID-19 spreads around the globe, so has misinformation about the virus. Log into any social media account and it’s easy to get confused by friends and family sharing contradictory messages on anything from infection rates, to local preventative measures, and what to do if we feel a dreaded cough coming on.

Truth matters – especially when public health is involved – and we often rely on journalists and news sources around the world to help us separate fact from fiction. And, whether we realize it or not, there’s a digital security tool that is a critical factor in the trust equation: encryption.

In a period that has seen various governments and law enforcement representatives propose laws that would weaken it, the pandemic is an important reminder of the role encryption plays to protect both journalists, their sources, and general news integrity.

End-to-end (E2E) encryption is a tool that keeps digital communications private by scrambling content so that only the sender and receiver have the keys to unscramble and read it.

This is crucial for journalists.

Journalists often rely on secure communication services like E2E messaging apps to connect with sources in a trustworthy way. With COVID-19 spreading, many organizations Continue reading

Migrating to React land: Gatsby

I am an engineer that loves docs. Well, OK, I don’t love all docs but I believe docs are a crucial, yet often neglected element to a great developer experience. I work on the developer experience team for Cloudflare Workers focusing on several components of Workers, particularly on the docs that we recently migrated to Gatsby.

? We’ve moved the Cloudflare Workers docs to @gatsbyjs

The new documentation is...

?‍♀️ faster
⭐️ more accessible
? a perfect foundation for the redesign later this year
?️ open-source

shout out to @exvuma for this incredible work ??https://t.co/k3huvCvash pic.twitter.com/MBWxVtlrin

— Cloudflare Developers (@CloudflareDev) March 4, 2020

Through porting our documentation site to Gatsby I learned a lot. In this post, I share some of the learnings that could’ve saved my former self from several headaches. This will hopefully help others considering a move to Gatsby or another static site generator.

Why Gatsby?

Prior to our migration to Gatsby, we used Hugo for our developer documentation. There are a lot of positives about working with Hugo - fast build times, fast load times - that made building a simple static site a great use case for Hugo. Things started to Continue reading

MUST READ: The World in Which IPv6 Was a Good Design

A lot of people are confused about the roles of network layers (some more than others), the interactions between MAC addresses, IP addresses, and TCP/UDP port numbers, the differences between routing and bridging… and why it’s so bad to bridge across large distances (or in large networks).

I tried to explain most of those topic in How Networks Really Work webinar (next session coming on April 2nd), but as is usually the case someone did a much better job: you MUST READ the poetic and hilariously funny World in which IPv6 was a good design by Avery Pennarun.

Survey: Most data centers don’t meet the needs of their users

A joint report released by Forbes Insights and Vertiv found that just 29% of data-center decision-makers say their current facilities are meeting their needs, and only 6% say their data centers are updated ahead of their needs.In yet another example of the disconnect between executives and people on the front lines, 11% of executives believe their data centers are updated ahead of current bandwidth needs, while just 1% of engineers feel the same way.Future data centers, the report says, will inevitably require adequate processing power – locally in the cloud and at the edge – to effectively manage new challenges around bandwidth, security and technologiesAI, advanced analytics, 5G, edge computing and more.To read this article in full, please click here

How enterprise networking is changing with a work-at-home workforce

As the coronavirus spreads, public and private companies as well as government entities are requiring employees to work from home, putting unforeseen strain on all manner of networking technologies and causing bandwidth and security concerns.  What follows is a round-up of news and traffic updates that Network World will update as needed to help keep up with the ever-changing situation.  Check back frequently!UPDATE 4.3 In an April 2nd call with the Federal Communications Commission chair, the nation’s largest telecom and broadband providers reported network usage during the COVID-19 pandemic had risen about 20-35% for fixed networks and 10-20% for cellular networks in recent weeks. In general, company representatives reported that their networks were holding up quite well, and they expected that resilience to continue. In their conversation with Chairman Ajit Pai, no providers expressed concern about their networks’ ability to hold up to increased and changing demand. To read this article in full, please click here

In a March 25 post the firm wrote: “Encouragingly, many of the areas hit hardest by the spread of the coronavirus are holding up to increased network demand. Cities like Los Angeles, Chicago, Brooklyn, and San Francisco have all experienced little or no disruption. New York City,  now the epicenter of the virus in the U.S., has seen a 24% dip out of its previous ten-week range. However, with a new median speed of nearly 52 Mbps, home connections still appear to be holding up overall.”To read this article in full, please click here
