Inflation Up, Economy Jittery, And IT Spending Consequentially Slows

The increasing cost of goods and services is making everyone a little crazy, and corporate IT departments are not immune from the effects of the dual concerns of rising inflation and the desire by central banks to use interest rates to curb our economic enthusiasm and slow that inflation to a much more sane level. …

Chatbot Attack Vectors And Failure Modes In Networking And IT

With the release of ChatGPT as a product, Microsoft brought Machine Learning (ML) and Artificial Intelligence (AI) back into focus for millions of users—including network operators, coders, and other folks in information technology. People are once against asking if this technology will make them redundant or how it might change their day-to-day jobs. As always, […]

Cisco: Maybe stop yanking on that Ethernet cable

Cisco issued field notices this week outlining what has apparently become a persistent issue: failed Ethernet connections due to a connected Webex device being moved around too much by pulling on its Ethernet cable.The product involved is the Cisco Webex Room Navigator, a small touchscreen device that combines on-screen, controls, sensors and a power-over-Ethernet port used as a controller for Webex conferencing devices and scheduling conference spaces.The problem, as the field notice describes, is that  “the Ethernet port might fail when the Cisco Room Navigator is pulled across the table by the Ethernet cable frequently over a period of several months.”To read this article in full, please click here

Consistent hashing algorithm

 

This is a guest article by NK. You can view the original article Consistent hashing explained on systemdesign.one website.

At a high level, consistent hashing performs the following operations:

  1. The output of the hash function is placed on a virtual ring structure (known as the hash ring)
  2. The hashed IP addresses of the nodes are used to assign a position for the nodes on the hash ring
  3. The key of a data object is hashed using the same hash function to find the position of the key on the hash ring
  4. The hash ring is traversed in the clockwise direction starting from the position of the key until a node is found
  5. The data object is stored or retrieved from the node that was found

 

Understanding DPUs For Network Engineers – Packet Pushers Livestream With Dell Technologies – Video

This video looks at the fundamentals of Data Processing Units (DPUs) and what they can do with an eye toward helping network engineers and infrastructure professionals. Greg Ferro from the Packet Pushers and Joseph White, a Fellow at Dell Technologies, discuss how DPUs are different from GPUs and CPUs; using DPUs to offload workloads from […]

Day Two Cloud 183: How Did We Get To WebAssembly And What Is It For?

WebAssembly (Wasm) is an up-and-coming technology that's probably going to fall into the lap of operations folks. WebAssembly is basically a specification on how to compile things to a bytecode format and how to execute that bytecode. On today's Day Two Cloud we start to peel the onion on what WebAssembly, what it's used for, and why you might want to get your hands on it.

Using Red Hat Insights as a source of events for Event-Driven Ansible automation

insights and event driven blog

One of the key announcements at AnsibleFest 2022 was the introduction of the Event-Driven Ansible developer preview. This technology is currently available on GitHub and accessible by technology providers and end users to provide feedback and drive the ecosystem. ISVs and consulting/service partners are specifically invited to create event driven automation content that makes it easy for customers to use in joint solutions.

 

Red Hat Insights events as a source for Event-Driven Ansible

Red Hat Insights, is a managed service that is included in every Red Hat subscription. It continuously analyzes platforms and applications to help enterprises manage hybrid cloud environments, and can trigger events through its Notifications service. Each account configures how and who can receive these events, with the ability to perform actions depending on the event type. For example, one may want to forward new recommendations found for Red Hat Enterprise Linux (RHEL) system configuration to a specific team by email, and/or create a new ticket in ServiceNow for the Operations team to handle. Others may want to forward all triggered events to Splunk for external analysis and troubleshooting. Through its Integrations service, Insights provides end-point integrations to Splunk, ServiceNow, Slack, as well as Continue reading

AWS boosts its infrastructure for memory-intensive tasks

Amazon Web Services (AWS) has announced availability of its new Amazon EC2 M7g and R7g instances, the latest generation of instances for memory-intensive applications and running Amazons custom Arm processor, known as Graviton3.This is the second offering of Graviton3-based instances from AWS. It previously announced specific instances for compute-intensive workloads last May.Both the M7g and the R7g instances deliver up to 25% higher performance than equivalent sixth-generation instances. Part of the performance bump comes from the adoption of DDR5 memory, which offers up to 50% higher memory bandwidth than DDR4. But there’s also considerable performance gain from the new Graviton3 chip.To read this article in full, please click here

Tailoring your Linux command prompt

The command prompt in a Linux terminal window is often just a $ unless you’ve logged in or sudo’ed your way into the root account, in which case you'd expect a #.Sometimes, though, your prompt will be more complicated, with a format like [lucky@fedora ~]$. But it's possible to change your prompt to some friendlier character, word, or phrase, and if you’re so inclined, you can even change its color. This post shows how easy it is to make these kinds of changes.Changing the format To get started, one thing you need to know is that your command prompt is not just something your shell creates on the fly. Instead, it’s a variable and its name is PS1. To see how your prompt is defined, display its value like this:To read this article in full, please click here
