We’ve been closely following momentum with Fujitsu’s Arm-based A64FX processor, from its inception to its placement inside the world’s most powerful supercomputer. …
The community around the open-sourced Software for Open Networking in the Cloud (SONiC) NOS got a little stronger as Apstra says its intent-based networking software is now more ready for enterprise prime-time than implementations from Cisco and Arista.The Linux-based NOS, developed and open sourced by Microsoft in 2017, decouples network software from the underlying hardware and lets it run on switches and ASICs from multiple vendors while supporting a full suite of network features such as border gateway protocol (BGP), remote direct memory access (RDMA), QoS, and other Ethernet/IP technologies.To read this article in full, please click here

There are actually quite a few resources out there for a novice programmer to learn about data types like strings, integers, floats, and more. The wikipedia page, as an example, covers a broad spectrum of potential meanings. Just about any book or tutorial focused on a particular programming language will start off by listing the types supported by that language. This makes sense, since they are the fundamental building block of being able to do pretty much anything in that language.
Nearly 70% of the 500 fastests supercomputers in the world as announced at the Supercomputing 20 conference this week are powered by Nvidia, including eight of the top 10.Among them was one named Selene that Nvidia built itself and that debuted at Number 5 on the semi-annual TOP500 list of the fastest machines. With top-end systems requiring 10,000 or more CPUs and GPUs, they are enormously expensive, so government or research institutions own the majority of them.That makes Selene all the more rare. It was built by and is based at Nvidia's Santa Clara, California, headquarters. (It’s widely believed there are many supercomputers in private industry that are not reported for competitive reasons.)To read this article in full, please click here

Is vendor lock-in all that bad? Many argue yes. You’re tied to a vendor because you’ve used some of their proprietary technology, and so you’re (apparently) stuck with it forever, limiting your future business agility. I think that’s an incomplete argument, though.
Over the next few years, we can expect to hear even more about large-scale computing sites bumping up against the memory wall, although not necessarily where they might expect. …
some time ago we’ve been recently engaged in the troubleshooting of the performance issues. Namely, the speed of the communication between the application’s endpoints in two data centres was not persistent. Instead, it was deviating a lot having multiple TCP retransmissions for certain flows. The issues was successfully solved, and we’d like to share with you the tools we have used to identify and validate various aspects of traffic forwarding.

Can automation help with performance troubleshooting?
Absolutely. During our network automation training we show how to utilise various Linux tools from configuration management tools (e.g. Ansible) and programming languages (Bash, Python). That gives you ready examples from our training, which you can use in your network immediately, and endless possibilities to create your own automated troubleshooting workflows.
How can managers grow teams that add value to the company? Teams are made up of people, and people need to grow, so the key is in learning how to grow people. Join us at the Hedge as we discuss learning paths, doing what’s right for the company and the person, and growing teams by growing people.
When it comes to advanced technologies at the high end of compute, networking, and storage, Lawrence Livermore National Laboratory is one of the world’s pathfinding testbeds. …
Cisco Tetration enables microsegmentation and application dependency mapping for on-premises and cloud applications. This Briefings In Brief explores essential details on Tetration, including how it works and how it fits with other products in Cisco's portfolio. This briefing is based on a Security Field Day presentation by Cisco on the Tetration product.

Open Policy Agent (OPA, pronounced “oh-pa”) for cloud native environments was created, and policy enforcement in code became much more practical. Now, its developers, under their company, new three-tier product offering for Styra Declarative Authorization Service (DAS).
Before diving into DAS, though, let’s make sure we’re all on the same page with OPA and policies in general.
OPA is an open source, general-purpose policy engine that unifies policy enforcement across the stack. You write these policies in its high-level declarative language Datalog query language. With Rego, you can specify policy as code and create simple APIs to offload policy decision-making from your software. You can then use OPA to enforce policies in microservices, Kubernetes, CI/CD pipelines, API gateways, and more.
And, what’s a policy engine you ask?
There's a light at the end of the tunnel for IT pros who have been keeping a close eye on the job market. Plus, here are the skills that employers want in 2021.
[Published on behalf of the Internet Society Board of Trustees]
As we announced some time ago, the Board of Trustees of the Internet Society (ISOC) has established the Governance Reform Working Group in order to host open community discussion on the general topic of potential governance changes at the Internet Society. We would like to welcome all members of any Internet Society Chapter, Organization Member, SIG, as well as individual members and IETF participants to contribute to this effort. Please, find the initial charter for the working group at: https://www.internetsociety.org/board-of-trustees/governance-reform-working-group-charter/
Olga Cavalli and Mike Godwin will be the chair and vice-chair of the working group, respectively. You can subscribe to the working group’s mailing list in order to contribute to the discussion on the following link (where you can also check the mailing list archives) : https://elists.isoc.org/mailman/listinfo/governance-reform

IBM has announced a definitive agreement to acquire Instana, an application performance monitoring firm. Financial details were not disclosed.Once the acquisition closes, Instana's technology will be incorporated into IBM's hybrid cloud and artificial intelligence portfolios – two markets IBM leadership has targeted for high growth in the coming years. To that end, IBM recently said it would spin off the $19 billion Managed Infrastructure Services unit of its Global Technology Services division to help the company focus on hybrid cloud, AI and quantum computing.
