Top IT vendors report good financials, onging supply woes

While key network vendors continue to report good financial results, all of the players report continued supply-chain issues and increased order backlogs—challenges that show little sign of abating before the end 2023.Arista supply issues A good example is Arista Networks, which reported its first billion dollar quarter in its history despite the “challenges of an uncertain supply-chain environment,” Jayshree Ullal, Arista President and CEO said during the firm’s Q2 financial call this week.

Load Balancing with Weighted Pools

Load Balancing with Weighted Pools
Load Balancing with Weighted Pools

Anyone can take advantage of Cloudflare’s far-reaching network to protect and accelerate their online presence. Our vast number of data centers, and their proximity to Internet users around the world, enables us to secure and accelerate our customers’ Internet applications, APIs and websites. Even a simple service with a single origin server can leverage the massive scale of the Cloudflare network in 270+ cities. Using the Cloudflare cache, you can support more requests and users without purchasing new servers.

Whether it is to guarantee high availability through redundancy, or to support more dynamic content, an increasing number of services require multiple origin servers. The Cloudflare Load Balancer keeps our customer’s services highly available and makes it simple to spread out requests across multiple origin servers. Today, we’re excited to announce a frequently requested feature for our Load Balancer – Weighted Pools!

What’s a Weighted Pool?

Before we can answer that, let’s take a quick look at how our load balancer works and define a few terms:

Origin Servers - Servers which sit behind Cloudflare and are often located in a customer-owned datacenter or at a public cloud provider.

Origin Pool - A logical collection of origin servers. Most pools Continue reading

AWS — Setting up Kinesis Video Stream is extremely easy with AWS Deeplens

<MEDIUM: https://raaki-88.medium.com/aws-setting-up-kinesis-video-stream-is-extremely-easy-with-aws-deeplens-ba13263c9cda&gt;

Note : I wanted to quickly demo out Kinesis video streaming, I initially thought a local-mac was a good candidate, installation was extremely painful, then I created a ubuntu VM 22.04 had errors, then went to ubuntu 20.04, everything was fine but vmware abstraction was very poor for reason and camera was extremely slow, then finally I have decided that I will compile everything on AWS deeplens (which is inherently had ubuntu as base-os) but looks like deeplens has already covered installation of KVS module which I will write up below.

I was reading about Kinesis and power of Kinesis for huge pipelines of inbound data from various sources, what impressed me was Kinesis could be integrated into AWS Rekognition and AWS sagemaker as well to analyze various points of data streamed in real time video or saved video, apart from that AWS-IOT youtube channel is also planning out new series on integration of AWS Kinesis with S3 for image collection completely from Kinesis streaming video itself.

This is the URL that I have used to follow the process and it was pretty straight forward

Learning to Ride

Have you ever taught a kid to ride a bike? Kids always begin the process by shifting their focus from the handlebars to the pedals, trying to feel out how to keep the right amount of pressure on each pedal, control the handlebars, and keep moving … so they can stay balanced. During this initial learning phase, the kid will keep their eyes down, looking at the pedals, the handlebars, and . . . the ground.

After some time of riding, though, managing the pedals and handlebars are embedded in “muscle memory,” allowing them to get their head up and focus on where they’re going rather than on the mechanical process of riding. After a lot of experience, bike riders can start doing wheelies, or jumps, or off-road riding that goes far beyond basic balance.
Network engineer—any kind of engineering, really—is the same way.

At first, you need to focus on what you are doing. How is this configured? What specific output am I looking for in this show command? What field do I need to use in this data structure to automate that? Where do I look to find out about these fields, defects, etc.?

The problem is—it is easy to get Continue reading

Intel kills Optane amid cost cutting

Optane, the memory technology pioneered and championed by Intel, has seen its last days. Intel has decided to wind down the technology as part of a refocusing effort.The news came on an earnings call with analysts to discuss Intel’s rocky second quarter. Since Pat Gelsinger has taken the reigns at Intel, the company has divested itself of McAfee (although that process began before Gelsinger arrived) as well as shed its drone business, NAND products, RealSense visual sensors, and Intel Sports.

Running Zig with WASI on Cloudflare Workers

Running Zig with WASI on Cloudflare Workers
Running Zig with WASI on Cloudflare Workers

After the recent announcement regarding WASI support in Workers, I decided to see what it would take to get code written in Zig to run as a Worker, and it turned out to be trivial. This post documents the process I followed as a new user of Zig. It’s so exciting to see how Cloudflare Workers is a polyglot platform allowing you to write programs in the language you love, or the language you’re learning!

Hello, World!

I’m not a Zig expert by any means, and to keep things entirely honest I’ve only just started looking into the language, but we all have to start somewhere. So, if my Zig code isn’t perfect please bear with me. My goal was to build a real, small program using Zig and deploy it on Cloudflare Workers. And to see how fast I can go from a blank screen to production code.

My goal for this wasn’t ambitious, just read some text from stdin and print it to stdout with line numbers, like running cat -n. But it does show just how easy the Workers paradigm is. This Zig program works identically on the command-line on my laptop and as an HTTP Continue reading
