Jinja template inheritance uses the concept of block to define sections of the base parent template that can be overridden by sections from a child template. An extends statement links the child template to the parent template so that when the child template is rendered the parent template is also rendered and the block statement contents inherited by the parent template.
I was curious the other day how hard it would be to actually set up my own blog or rather I was more interested in how easy it is now to do this with containers. There are plenty of platforms that host blogs for you but is it really now as easy to just run one yourself?
In order to get started, you can sign up for a Docker ID, or use your existing Docker ID to download the latest version of Docker Desktop Edge which includes the new Compose on ECS experience.
To start I setup a local WordPress instance on my machine, grabbing a Compose file example from the awesome-compose repo.
Initially I had a go at running this locally on with Docker Compose:
$ docker-compose up -d
Then I can get the list of running containers:
$ docker-compose ps
Name Command State Ports
--------------------------------------------------------------------------------------
deploywptocloud_db_1 docker-entrypoint.sh --def ... Up 3306/tcp, 33060/tcp
deploywptocloud_wordpress_1 docker-entrypoint.sh apach ... Up 0.0.0.0:80->80/tcp
And then lastly I had a look to see that this was running correctly:
Great! Now I needed to look at the contents of the Compose file Continue reading
Heavy Networking dives into building cost-effective, practical, and easily managed leaf-spine networks with sponsor Dell Technologies. We discuss Dell's SmartFabric Services offering, including the underlying infrastructure and software overlay, key automation features, interconnects for enterprise uses such as HCI, and more. Our guest is Saleem Muhammad, Director of Product Management and Marketing at Dell Technologies.

We can only be successful in creating an Internet for everyone if everyone is part of the effort. That’s why the Internet Society is thrilled to be entering into a partnership with the European Internet Exchange Association (Euro-IX).
The partnership was made official with a Memorandum of Understanding (MoU) on 14 July. This formal agreement builds on an existing collaboration between the two organizations, who have worked together since 2012. But, whether it’s helping to bring cheaper and faster Internet to the world through the data provided in the IXP Database or making the Internet more secure by supporting the Mutually Agreed Norms for Routing Security (MANRS), our work has only just begun.
Kjetil Otter Olsen, the chair of Euro-IX said, “The Internet Society has been an excellent supporter of Internet exchange points (IXPs) for many years and has lent the support of its teams across the world to promoting the benefits of peering for Internet networks and the end users of those networks globally.
“Signing this MoU, on behalf of Euro-IX and the community of IXPs we represent, reflects our shared commitment with the Internet Society to continue this work into the future.
“This MoU extends our existing relationship Continue reading
I think we’ve all been there. The network is down, you’ve tried all the things that you know how to do, and now it’s time to call vendor support to figure out what the heck is going on with your network. Some of us dread this situation as navigating the support process can be daunting at times. We’re hoping to give you some tips in today’s episode to make that process go a little smoother. Listen in as we talk about our experiences with vendor support and what we’ve learned along the way to make the support process as painless as possible.

Here at the Internet Society, we believe that the Internet is for everyone. Our work centers on increasing the Internet’s reach, reliability and resilience, as well as ensuring that the network of networks remains open, globally connected, secure, and trustworthy.
But how do we assess whether our efforts – and the efforts of the global ecosystem of organizations that facilitate the smooth functioning of the Internet – are working? How can we see where protocols, such as IPv6, are being deployed and at what rate so we can better understand where more education on the benefits of such technologies might be helpful? Where can policy makers find a comprehensive set of data from various sources to help show decision makers that Internet Showdowns damage local economies and potentially harm citizens?
A Single Platform
There are many people, projects and organizations that are collecting data on various facets of the Internet, but there’s no single site that provides a curated set of insights. So, to help everyone gain deeper, data-driven insight into the Internet, the Internet Society is building a tool that consolidates trusted third-party Internet measurement data from various sources into a single platform – insights.internetsociety.org.

For me, 2020 is going to be the year of taking my automation skills to the next level, and a Pandemic is not going to get in the way of that goal (much)! At the top of the list is handling credentials and API keys in a more secure fashion so lets look at how READ MORE

For those not following the current state of the ITU, a proposal has been put forward to (pretty much) reorganize the standards body around “New IP.” Don’t be confused by the name—it’s exactly what it sounds like, a proposal for an entirely new set of transport protocols to replace the current IPv4/IPv6/TCP/QUIC/routing protocol stack nearly 100% of the networks in operation today run on. Ignoring, for the moment, the problem of replacing the entire IP infrastructure, what can we learn from this proposal?
What I’d like to focus on is deterministic networking. Way back in the days when I was in the USAF, one of the various projects I worked on was called PCI. The PCI network was a new system designed to unify the personnel processing across the entire USAF, so there were systems (Z100s, 200s, and 250s) to be installed in every location across the base where personnel actions were managed. Since the only wiring we had on base at the time was an old Strowger mainframe, mechanical crossbars at a dozen or so BDFs, and varying sizes of punch-downs at BDFs and IDFs, everything for this system needed to be punched- or wrapped-down as physical circuits.

A firewall is a firewall, right? While on the surface that assumption may appear to be correct, a closer look reveals that there are critical differences between a traditional, appliance-based firewall that protects your network perimeter and a distributed, scale-out internal firewall that protects east-west traffic within your data center.
It’s true that both types of firewalls monitor network traffic, detect threats, and block malicious activity. However, appliance-based firewalls are designed to monitor north-south traffic, which has different volumes and characteristics than east-west traffic. Traditional north-south firewalls were never designed to be used interchangeably to protect both north-south and east-west traffic.
Figure 1: Data center traffic patterns
While it might appear to be the right choice, provisioning appliance-based firewalls for east-west traffic monitoring is not only expensive, it’s highly ineffective in delivering the level of control and performance required to protect growing numbers of dynamic workloads.
One of the most common drawbacks of using appliance-based firewalls as internal firewalls is the need to hairpin east-west traffic to and Continue reading
Scrubbing the Net: U.S. Secretary of State Mike Pompeo says he wants a “clean” Internet free of Chinese apps and network equipment, The Next Web reports. Pompeo also wants to keep U.S. cloud data away from Chinese companies and stop China from spying on traffic in undersea cables. Critics say Pompeo is trying to create a U.S. version of the Great Firewall of China. The Verge, meanwhile, says Pompeo’s announcement is “just bluster” for now.
NOTE: Please read the Internet Society’s statement on the U.S. Clean Network Program.
Trump vs. TikTok: In a related story, U.S. President Donald Trump has continued his fight against Chinese video app TikTok, recently issuing executive orders that would ban TikTok and fellow Chinese app WeChat in 45 days, CNet reports. Trump calls the use of these apps on U.S. devices a security problem, but he earlier gave TikTok time to sell to a more acceptable owner. Microsoft is interested in buying the video app.
Buy local: In yet another related story, the Economic Times reports that the use of locally made apps are surging after the Indian government took its own action against Chinese apps. In late June, Continue reading
