One Way To Bring DPU Acceleration To Supercomputing
That is not a typo in the title. We did not mean to say GPU in title above, or even make a joke that in hybrid CPU_GPU systems, the CPU is more of a serial processing accelerator with a giant slow DDR4 cache for GPUs in hybrid supercomputers these days – therefore making the CPU a kind of accelerator for the GPU. …

What Does A Good Network Design Look Like? – James Bensley, Senior Network Design Engineer
Is a good network design just about technical specifications or should you take into account business drivers and needs? James is a network design veteran and presented on this topic at UKNOF45. We talk about design considerations, tips and tricks, drivers and motivations, asking the question behind the question and even about a book that is ‘in the works’. James is very active on Twitter, LinkedIn and can be reached via [email protected].

Lenovo Spreads The AI Message Far And Wide
Artificial intelligence and machine learning are foundational to many of the modernization efforts that enterprises are embracing, from leveraging them to more quickly analyze the mountains of data they’re generating and automating operational processes to running the advanced applications – like natural language processing, speech and image recognition, and machine vision – needed by a broad array of industries, from financial services, agriculture, healthcare and automotive. …

What developers need to know about Docker, Docker Engine, and Kubernetes v1.20
The latest version of Kubernetes Kubernetes v1.20.0-rc.0 is now available. The Kubernetes project plans to deprecate Docker Engine support in the kubelet and support for dockershim will be removed in a future release, probably late next year. The net/net is support for your container images built with Docker tools is not being deprecated and will still work as before.
Even better news however, is that Mirantis and Docker have agreed to partner to maintain the shim code standalone outside Kubernetes, as a conformant CRI interface for Docker Engine. We will start with the great initial prototype from Dims, at https://github.com/dims/cri-dockerd and continuing to make it available as an open source project, at https://github.com/Mirantis/cri-dockerd. This means that you can continue to build Kubernetes based on Docker Engine as before, just switching from the built in dockershim to the external one. Docker and Mirantis will work together on making sure it continues to work as well as before and that it passes all the conformance tests and works just like the built in version did. Docker will continue to ship this shim in Docker Desktop as this gives a great developer experience, and Mirantis will be Continue reading
Starlink Hands On: Finally, Internet
Starlink may soon be a viable alternative for remote workers who currently lack broadband connectivity services, particularly those in rural areas. Here, Eric Rux takes a deep dive into the service.MANRS Welcomes 500th Network Operator
Today, we are glad to share a milestone for the Mutually Agreed Norms for Routing Security (MANRS) initiative: the number of participants in the network operator program has reached 500.
By joining the community-driven initiative, these network operators, big and small, from around the world have taken specific, concrete actions to improve the resilience and security of the Internet’s inherently insecure routing infrastructure.
Systemic security issues about how traffic is routed on the Internet make it a relatively easy target for criminals. MANRS helps reduce the most common routing threats and increase efficiency and transparency among Internet service providers (ISPs) on peering relationships.
The growth of the network operator program – the oldest among three today – has been accelerating in recent years. Launched in 2014 with a group of nine operators, the number of participants in the program took four years to reach 100 in 2018 and has risen sharply in the last two years, with 156 joining in 2019 and 244 so far in 2020.
The 500 network operators manage 651 autonomous systems in total, as some of them manage multiple networks.
Meanwhile, the Internet Exchange Point (IXP) program, which we launched in 2018, now has 60 Continue reading
Fast Failover: Techniques and Technologies
Continuing our Fast Failover saga, let’s focus on techniques and technologies available to implement it (assuming you still think it’s worth the effort).
The following text is heavily based on comments Jeff Tantsura wrote on one of my LinkedIn posts as well as the original blog post. Thank you!
There are numerous technologies you can use to implement fast reroute, from the most complex to the easiest one:

Rails Generators Cheat Sheet
As I am digging into Rails again I find myself constantly having to look the naming and syntax of generators up so I am documenting them in this post. Rails utilizes convention over configuration to speed up development and increase developer happiness. If you embrace this fact you will...Bypassing safety check for an obviously safe change
This is less concrete technical than my usual blog post.
For every 100 changes we’re 99% sure won’t cause an outage, one will
It’s actually hard to be 99% sure of anything. I’m not 99% sure today’s Thursday. I say that because more often than one day in a hundred, I’ll think “hmm… feels like Wednesday” when it’s not.
I just closed my eyes and tried to remember what time it is. I don’t think I can guess with 99% accuracy what hour I’m in. (but to be fair, it’s de-facto Friday afternoon today, as I’m off tomorrow).
Anyway… the reason I say this is that this should be kept in mind every time someone comes and says they want to circumvent some process for a change that they are absolutely sure won’t cause an outage, that can actually be put into numbers. And those numbers are “you are not 100% sure of anything”.
By saying you are 99% sure this won’t cause an outage (and are you right about that?) you are saying that for every 100 requests like yours that will bypass normal checks, there will be an outage. You are taking on an amortized 1% of Continue reading
Broadcom Widens And Smartens Switch Chip Lineup
Cisco Systems may still be the biggest supplier of switches and routers in general, but it has long since been surpassed by Broadcom when it comes to suppling the silicon that does the switching itself and sometimes even a little bit of routing in the datacenter in particular. …

After the failure to launch a market sector in the 1990s, a largely new field of players is betting big on high-speed services for a very different world.Join Docker’s Community All-Hands
Openness and transparency are key pillars of a healthy open source community. We’re constantly exploring ways to better engage the Docker community, to better incorporate feedback and to better foster participation.
To this end, we’re very excited to host our first Community All-Hands on Thursday December 10th at 8am PST / 5pm CET. This one-hour event will be a unique opportunity for Docker staff and the broader Docker community to come together for company and product updates, live demos, community shout-outs and a Q&A.
The All-Hands will include updates from:
- Scott Johnston (CEO, Docker) who will go over Docker’s strategic vision and where the company is heading in 2021 and beyond
- Donnie Berkholz (VP of Products, Docker) who will walk us through our product roadmap
- Jean-Laurent de Morlhon (VP of Engineering, Docker) who will provide an inside peek on engineering.
We’ll then dive into specific product updates around Docker Desktop, Hub and Developer Tooling, followed by two awesome live demos where we’ll show cool new features and integrations.
A Community All-Hands is not complete without a community update. We will announce new community initiatives and recognize outstanding contributors who have gone above and beyond to help push Docker Continue reading
