CloudFlare launched yet another service: transfer speed- and latency measurements done from a web browser. While it’s pretty obvious how you could measure transfer speed (start an asynchronous transfer, register for the JavaScript onreadystatechange event to notice out when it has completed, and compute the transfer rate), measuring latency seems like a bit of black magic. After all, you can’t do a ping from a web browser, can you?
VMware Announces Intent to Acquire Lastline
By Tom Gillis, SVP and GM, Networking and Security Business Unit, VMware
EDITORIAL UPDATE: On June 18, 2020 VMware officially closed its acquisition of Lastline. The blog post below has been amended to reflect that announcement.
VMware announced its intent to acquire Lastline, a pioneer in anti-malware research and AI-powered network detection and response, and on June 18, 2020 the acquisition closed. This is an important step forward for VMware’s vision of Intrinsic Security, as it allows us to further take advantage of the intrinsic attributes of our virtualization platform to yield innovative security capabilities. Our aim is not to replicate that which exists today, but rather to build security solutions that we can uniquely deliver, spanning from the heart of the data center to users in a branch office and all the way to mobile users at home or on the road.
In the security industry, the nature of threats changes so rapidly that security technology is constantly being re-invented. In this context, it is not the algorithms per se that matter; it is the people that make the algorithms. Great people build great products, and great products build great companies. And that’s why we are so Continue reading

Enabling IPv6 in AWS Deployments
IPv6 is old enough to buy its own beer (in US, not just in Europe), but there are still tons of naysayers explaining how hard it is to deploy. That’s probably true if you’re forced to work with decades-old boxes, or if you handcrafted your environment with a gazillion clicks in a fancy GUI, but if you used Terraform to deploy your application in AWS, it’s as hard as adding a few extra lines in your configuration files.
Nadeem Lughmani did a great job documenting the exact changes needed to get IPv6 working in AWS VPC, including adjusting the IPv6 routing tables, and security groups. Enjoy ;)
Deploying IPv6 is just one of many hands-on exercises you have to solve in our Networking in Public Cloud Deployments online course.

Introduction to YAML
Introduction
YAML, previously known as Yet Another Markup Language, but now YAML Ain’t Markup Language, is a human friendly data serialization standard for programming languages.
YAML and JSON, JavaScript Object Notation, are related to each other, where YAML, according to YAML 1.2 specification, is a superset of JSON.
YAML supports using scalars, sequences, and mappings. A scalar is a string, a number, or boolean, a sequence is a list, and a mapping is a key/value pair.
YAML is commonly used by configuration files in open source tools and Ansible, a network automation tool, uses YAML to run its playbooks.
When it comes to YAML syntax, be aware of the following:
- Indentation matters!
- Tabs aren’t allowed
- Normally two spaces used when indenting
- A single YAML file may contain multiple documents
- Every document starts with three dashes
- YAML is case sensitive
Scalars
Scalars are single values. It can be a string, number, or a boolean value. Strings don’t need to be quoted, except for some special cases:
- The string starts with a special character
- !#%@&*`?|>{[ or –
- The string starts or ends with whitespace characters
- The string contains : or # character sequences
- The string ends with a Continue reading
