Fast Reroute, Fast Convergence, WRED and WFQ

Fast Reroute , Fast Convergence , WRED and WFQ. You may think that why Orhan is putting all these mechanisms together. I will give you an analogy. Those who participate my talks., know that I love using analogies.  Before we try to understand how these mechanisms are related with each other, let me explain what …

FTC fines YouTube, but do fines really encourage change? | TECH(feed)

The FTC hit yet another tech company with a seemingly massive fine for mishandling user data. This time, YouTube, owned by Google, is forced to pay $170 million for collecting data about children under 13 without parental consent. The Federal Trade Commission slapped Facebook with a $5 billion fine just a few months ago. In this episode of TECH(feed), Juliet asks whether or not these fines are effective in regulating the tech industry.

USB4 gets final approval, offers Ethernet-like speed

The USB Implementers Forum (USB-IF), the industry consortium behind the development of the Universal Serial Bus (USB) specification, announced this week it has finalized the technical specifications for USB4, the next generation of the spec.One of the most important aspects of USB4 (they have dispensed with the space between the acronym and the version number with this release) is that it merges USB with Thunderbolt 3, an Intel-designed interface that hasn’t really caught on outside of laptops despite its potential. For that reason, Intel gave the Thunderbolt spec to the USB consortium.Unfortunately, Thunderbolt 3 is listed as an option for USB4 devices, so some will have it and some won’t. This will undoubtedly cause headaches, and hopefully all device makers will include Thunderbolt 3.To read this article in full, please click here

AnsibleFest Atlanta – Culture and Collaboration

 

Now that AnsibleFest is right around the corner, we wanted to take a closer look at each of the tracks that we will offer. We talked with Track Lead Brian Coursen and asked him a few questions about the Culture and Collaboration Track and sessions within the track.  

 

Who is this track best for? 

This track is best for attendees that want to see how Ansible is used and how it brings people and teams together in the workplace.

 

What topics will this track cover? 

Topics will include how to create an automation culture as well as highlight some automation use cases. This will include minimizing business unit conflict with patch automation, how to build an open source network service orchestrator using Ansible at the core, and why automation isn't just a passing fad but a necessity in today's enterprise.

 

What should attendees expect to learn from this track? 

Attendees will learn about DevOps culture and automation. They will also learn about how places like National Weather Service Southern Region; Datacom; and the British financial institution, RBS, are all using Ansible to create a culture of collaboration.

Data center cooling: Electricity-free system sends excess building heat into space

We all know that blocking incoming sunlight helps cool buildings and that indoor thermal conditions can be improved with the added shade. More recently, though, scientists have been experimenting with ways to augment that passive cooling by capturing any superfluous, unwanted solar heat and expelling it, preferably into outer space, where it can’t add to global warming.Difficulties in getting that kind of radiative cooling to work are two-fold. First, directing the heat optimally is hard.“Normally, thermal emissions travel in all directions,” says Qiaoqiang Gan, an associate professor of electrical engineering at University at Buffalo, in a news release. The school is working on radiative concepts. That’s bad for heat spill-over and can send the thermal energy where it’s not wanted—like into other buildings.To read this article in full, please click here

The Inevitable Slowdown In Server Spending

It had to happen sooner or later, and really, the wonder is that it hasn’t already happened, given the nature of the infrastructure buildouts at hyperscalers and cloud builders, the skittishness of enterprises due to the trade war between the United States and China, the uncertainty in Europe over the British exit, and general concern with macroeconomic issues because it has now been almost twelve years since the last recession. …

The Inevitable Slowdown In Server Spending was written by Timothy Prickett Morgan at The Next Platform.

IPv6 Buzz 034: Why AWS Embraces IPv6

AWS regards IPv6 as a key mechanism to enable customer agility, and to meet rising demands from new applications and devices, particularly IoT. In this episode, Scott and Tom interview Alan Halachmi, Senior Manager of Solutions Architecture at AWS. They discuss current and planned IPv6 support in AWS services, the cloud provider's challenges in deploying the protocol, and advice for cloud users on adopting IPv6.

Fast WordPress Sites with Bluehost & Cloudflare Workers

WordPress is the most popular CMS (content management system) in the world, powering over a third of the top 10 million websites, according to W3Techs.

WordPress is an open source software project that many website service providers host for end customers to enable them to build WordPress sites and serve that content to visitors over the Internet.  For hosting providers, one of the opportunities and challenges is to host one version of WordPress on their infrastructure that is high performing for all their customers without modifying the WordPress code on a per customer basis.

Hosting providers are increasingly turning to Cloudflare’s Serverless Workers Platform to deliver high performance to their end customers by fixing performance issues at the edge while avoiding modifying code on an individual site basis.

One innovative WordPress hosting provider that Cloudflare has been working with to do this is Bluehost, a recommended web host by WordPress.org. In collaboration with Bluehost, Cloudflare’s Workers have been able to achieve a 40% performance improvement for those sites running Workers. Bluehost started with Cloudflare Workers code for Fast Google Fonts which in-lines the browser-specific font CSS and re-hosts the font files through the page origin. This removes the multiple Continue reading
