As part of a POC I deployed a pair of HA F5 LTM/GTM at home to use for all things DNS based. It is an indulgent over the top DNS solution for a 1 bed flat, but hey-ho we are in a pandemic….. This guide does not go through the HA F5 or GTM (still cant stop calling it that) configuration, it is focussed around using ZoneRunner for DNS (bind) with these zones transferred into DNS express and serviced by a listener.
A friend of mine recently had a solar panel system installed on his acreage. Besides being interesting because of the renewable/green aspect of the project, the system itself—from SolarEdge—is actually highly digital.
The last point interested me the most because any time a device exposes its data or a control connection, it means there’s an opportunity to integrate it with other software. In this case, I wanted to create my own dashboard to display (near) real-time performance data for the system.
Whereas other blogs and articles on this topic describe how to monitor a single inverter system, this post will describe how I built a performance dashboard for a multi-inverter system.

As Discussed in Part-1 SRIOV (Enhanced Networking on EC2) can be enabled in two ways, the first in the series is by far the simplest one, Enabling it with using ENA (Elastic Network Adapter).
Great, would that work for any instance – The answer is NO!, below are the specifications, to make summarize any Instance other than C4, D2, M4 instances smaller than m4.16xlarge, or T2 from current generation Instances.
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking-ena.html
How do I Check:
The Latest Ubuntu / Amazon Linux AMI include the module required for Enhanced networking with ENA installed and enabled for support, if you happen to use the old AMI’s the procedure listed in the above webpage will help
Testing:
I spin up a T3.large instance and below is how it looks like
You also have the option to verify it in a Cloud shell
How do you know if AMI supports it?
Finally on the interface itself
The next post will be similar but would cover an Intel specific Network Adapter.

I’m positive that this pointer to The Gift of It’s Your Problem Now by Avery Pennarun will generate similar comments to the blockchain one: “he’s an idiot, and you’re an idiot for wasting my time posting this”.
That might be true, but in that case he’s my kind of idiot, and you shouldn’t complain about a gift anyway – there are tons of high-quality lolcats videos waiting for you instead.

When my eldest son was just a baby, he had toys that looked like little baseballs. Long story short, I decided to teach myself to juggle with them. I’d always wanted to learn and thought to myself “How hard can it be?” Well, the answer was harder than I thought and it took me more time that I realized to finally get the hang of it.
One of the things that I needed to learn is that adding in one more ball to track while I’m trying to manage the ones that I had wasn’t as simple as it sounded. You would think that adding in a fourth ball should only be about 25% harder than the three you had been working with before. Or, you might even believe the statistical fallacy that you’re only going to fail about a quarter of the time and be successful the rest. The truth is that adding in one more object makes your entire performance subpar until you learn to adjust for it.
I mention this example because the most obvious application for the juggling metaphor is in Quality of Service (QoS). If you’ve ever read any of Continue reading

Every 11 seconds, a new organization falls victim to ransomware. That means by the time you’re done reading these two sentences, your organization could very well become another statistic. In the war against ransomware, there are two cohorts: those who are armed for war and those who will suffer digital casualties. With threats becoming increasingly more agile, it’s up to you to protect your organization’s past, present, and future.
The Numbers Don’t Lie
Cybercrime has become a bigger entity than any of us could’ve ever imagined. With over 4,000 attacks every day and $20 billion in damages in 2021 alone, ransomware has become the big business we’ve all feared. Imposing numbers like these make it seem nearly impossible to protect against ransomware – but there is a solution that will strengthen your armor.
Protection Served with Simplicity
We know that shopping for new digital armor can be daunting. But the threat is real, and VMware is not in the business of smoke and mirror solutions. We are, however, in the business of helping enterprises scale out – simply, securely, swiftly. To that end, the VMware Distributed Firewall is a foundational step for many customers strengthening their multi-cloud environments. Enforcing east-west advanced threat protection at each workload, our distributed firewall solution can scale to 20TB+ while coming in at one-third of the cost of other solutions in the industry. Providing support to over 30,000 customers, VMware Security Solutions have consistently been able to stop attackers in Continue reading
One of the things that makes Cloudflare unique is our Innovation Weeks. Rather than having one large conference annually, we have multiple Innovation Weeks throughout the year to highlight new product announcements, beta products opening up to general availability, and share how our customers are using Cloudflare to help build a better Internet.
Internally, these weeks generate a lot of energy and excitement as well, as they provide an opportunity for teams from across Cloudflare to work together on product delivery and celebrate company-wide successes. In 2021, we had seven Cloudflare Innovation Weeks. As we start planning our 2022 Innovation Weeks, we are reflecting back on the highlights from each of these weeks.

Security Week kicked off Cloudflare’s 2021 Innovation Weeks with a series of foundational security announcements. The Internet wasn’t built with security in mind, but the products and partnerships announced this week continued Cloudflare’s core mission of helping build a better Internet—one that companies of all sizes can plug into and be protected by default from the types of attacks that have historically resulted in loss of data, computing resources, and customer confidence.
At the start of the week, we took Continue reading

More Processor Performance Doesn’t Always Mean Better Performance was written by David Gordon at The Next Platform.
In July 2021, I launched Miniflare 1.0, a fun, full-featured, fully-local simulator for Workers, on the Cloudflare Workers Discord server. What began as a pull request to the cloudflare-worker-local project has now become an official Cloudflare project and a core part of the Workers ecosystem, being integrated into wrangler 2.0. Today, I'm thrilled to announce the release of the next major version: a more modular, lightweight, and accurate Miniflare 2.0. 🔥
At the end of 2020, I started to build my first Workers app. Initially I used the then recently released wrangler dev, but found it was taking a few seconds before changes were reflected. While this was still impressive considering it was running on the Workers runtime, I was using Vite to develop the frontend, so I knew a significantly faster developer experience was possible.
I then found cloudflare-worker-local and cloudworker, which were local Workers simulators, but didn’t have support for newer features like Workers Sites. I wanted a magical simulator that would just work ✨ in existing projects, focusing on the developer experience, and — by the reception of Miniflare 1.0 — I wasn't the only one.
We all have social anxiety to a certain extent. However, it is entirely normal, and you shouldn’t feel alone. That is because the fear of adverse reactions from people is evolutionary.
In most cases, anxiety can prevent you from enjoying an event. Not only that, but it can prevent you from attending altogether. As a business owner or an artist, networking is essential.
Hence, if you are looking for ways to control your anxiety, you no longer have to. Here is everything you need to know on how to deal with social anxiety when networking.
Here are the top tips that will help you overcome social anxiety while networking:
It is no secret that mindset can have a significant impact on your life. Your perception of anxiety can help you deal with it. One way to have a positive attitude is by being mindful.
Your nerves will calm once you start to accept your social anxiety. By avoiding the things that caused it will not help you. Instead, the fear will grow gradually and have greater power over your decisions.
However, by being mindful and having self-compassion, you can Continue reading
