DeepLearning – Intro Fun

I am enjoying insights into deep learning and computer vision and how machine learning is applied on images. While Deep Learning and Nueral networks are subjects for experts in field, I wanted simply to be an end user to do some experiments on my dog and nothing more. I have to mention that I had internal resources to get training on image augmentation techniques, DLL Nueral network frameworks pretrained to be used readily but am still trying to find some way into what this technology is all about and how to implement in my AWS Deeplens.

This is a good book to get introduced into pytorch and deep learning terminology. There is a very interesting examples of doing image manipulation of a horse to zebra, and how you can transfer that learning to anything.

Below is how I used on my Dog and results, I had fun starting this and hope you will have fun too, you dont need any great programming or math to just access some of the Neural networks and do some analysis

I wrote this post to let anyone interested to know that I dint had to write any complicated coding Continue reading

Cisco issues 3 critical warnings around ACI, NS-OX security holes

Cisco has issued three security advisories rated “critical” for some of its high-end software systems—two aimed at its Application Services Engine (ASE) implementation and one at the NX-OS operating system.The most concerning warning came for Cisco Application Centric Infrastructure (ACI) Multi-Site Orchestrator (MSO) installed with the ASE which was rated a worse-case scenario, 10 out of a possible 10 on the Common Vulnerability Scoring System (CVSS). The ACI Multi-Site Orchestrator lets customers control application-access policies across Cisco Application Policy Infrastructure Controller-based fabrics.To read this article in full, please click here

The Hedge #72: Lisa Caywood and Marketectures

The open source world is not much different than the commercial world in terms of building marketectures rather than useable software—largely because open source projects still rely on sources of funding and material support to build and maintain a product. Many times, however, the focus on these marketectures get in the way of real work. Join Tom Ammon, Russ White, and Lisa Caywood as we discuss the problem of marketectures and the broader world of open source software.

High Value Certifications For 2021 And Beyond

In looking back on 2020 we think about all of the things we did to keep ourselves busy.

Some of us starting baking bread at home, some started home gardens, and if you are part of the networking twitter community you probably saw a lot of folks chasing some new certifications.

Throughout 2020, with isolation and the pandemic in full swing, networking vendors and certification facilitators found ways to serve the community by providing remote exams and free trainings.

Whether it was the need to stay busy or trying to learn something new, whatever your reason is to pursue a new certification, the question is which one?

With 2020 now behind us and our future constantly changing, which certifications will give you the biggest impact for 2021 and beyond?

In today’s episode we talk to 2 prominent networking influencers:

Ernest the “Cisco Panther” and
Yasmin Lara the “mom who can fix anything”

We’ll go over topics covering

their certification journey
how it’s positioned them to continue growth throughout the pandemic and
which certifications give you the best bang for your buck for 2021 and beyond.

Linux server certifications becoming a must-have for IT pros

Linux certification is increasingly significant for tech workers as the public cloud and software-defined networking become ever more important. A Linux cert can set IT professionals apart from the herd and potentially put a lot more money in their bank accounts.Once these certifications were a gauge of reliability, according to CompTIA chief tech evangelist James Stanger. “Twenty years ago, Linux tended to attract people who were a little edgier,” he said. “So certification was traditionally used in the Linux side just to find people you can work with—will they show up on time?”Now, these certifications are a demonstration not only of proficiency but also dedication to self-improvement. “You can’t go wrong with a certification,” said Joe Faletra, director of infrastructure services at Modis, a technology staffing and consulting firm. “I’ll lean towards certs over experience [in hiring], because this person has put the effort into learning and passing the exam.”To read this article in full, please click here

IoT security tips and a cautionary tale

You will have more connected devices than ever on your network in 2021, especially if you’re in healthcare, retail, or logistics, industries that are among the early adopters of the Internet of Things (IoT). You’ll have devices on your network edge, in your headquarters, on vehicles, in machinery, in your stores, in employees’ homes, and on public property.And there’s a good chance that some or many of these IoT devices have built-in security vulnerabilities that can endanger your network. In trying to capitalize on the voracious global appetite for connected commercial devices, many IoT manufacturers and developers are shoveling out enterprise IoT devices with, shall we say, varying levels of regard for security.To read this article in full, please click here

Routing in Stretched VLAN Designs

One of my readers was “blessed” with the stretched VLANs requirement combined with the need for inter-VLAN routing and sub-par equipment from a vendor not exactly known for their data center switching products. Before going on, you might want to read his description of the challenge he’s facing and what I had to say about the idea of building stackable switches across multiple locations.

Of course it’s possible that my reader failed to explain the challenge in enough details to get good advice from the vendor SE, or that he had to deal with a clueless SE, or that he’s using ancient gear or that the stars just weren’t aligned… but I don’t think anyone should ever be painted into the corner he found himself in.

Here’s an overview diagram of what my reader was facing. The core switches in each location work as a single device (virtual chassis), and there’s MLAG between core and edge switches. The early 2000s just called and they were proud of the design (but to be honest, sometimes one has to work with the tools his boss bought, so…).
