Video: High-Level Technology Guidelines
I concluded the Focus on Business Challenges First presentation (part of Business Aspects of Networking Technologies webinar) with a few technology guidelines starting with:
- Be vendor-agnostic (always look around to see what others are doing);
- Try to understand how the technology you’re evaluating works (it will help you spot the potential problems before they crash your network);
- Always select what’s best for your business, not for the sales quota of your friendly $vendor account manager.

Looking at What’s Driving Edge Computing’s New Security Strategy
As edge computing grows, security teams must address the requirement for visibility and control across the LAN, WAN, and cloud edges.JNCIE-DC remote lab exam resources
Due to the COVID-19 pandemic the exam centers of Juniper are at time of this writing closed for external visitors. Fortunately the Juniper Education team did a great job and made JNCIE lab exams available from your own home! Now this does impact how you make the test and also what resources you have available […]

We've been experimenting with breaking up employees into random groups (of size 4) and setting up video hangouts between them. We're doing this to replace the serendipitous meetings that sometimes occur around coffee machines, in lunch lines or while waiting for the printer. And also, we just want people to get to know each other.
Which lead to me writing some code. The core of which is divide n elements into groups of at least size g minimizing the size of each group. So, suppose an office has 15 employees in it then it would be divided into three groups of sizes 5, 5, 5; if an office had 16 employees it would be 4, 4, 4, 4; if it had 17 employees it would be 4, 4, 4, 5 and so on.
I initially wrote the following code (in Python):
groups = [g] * (n//g)
for e in range(0, n % g):
groups[e % len(groups)] += 1
The first line creates n//g (// is integer division) entries of size g (for example, if g == 4 and n == 17 then groups == [4, 4, 4, 4]). The for loop deals with the 'left over' parts that Continue reading

Does Unequal-Cost Multipathing Make Sense?
Every now and then I’m getting questions along the lines “why doesn’t X support unequal-cost multipathing (UCMP)?” for X in [ OSPF, BGP, IS-IS ].
To set the record straight: BGP does support some rudimentary form of unequal-cost multipathing with the DMZ Bandwidth community, but it only works across multiple egress points from a single autonomous system. Follow-up nerd knobs described how to use the same community over EBGP sessions; not sure whether anyone implemented that part (comments welcome).

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.
https://pytorch.org/assets/deep-learning/Deep-Learning-with-PyTorch.pdf
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

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.
Natural Remedies For Dry Mouth When Public Speaking
Are you suffering from dry mouth? Well, anyone would be worried. But, you do not need to worry anymore. The good news is that there are some extremely handy natural and home remedies that will help you overcome the problem. Just follow the remedies and you will be able to get over the condition in no time. Want to know more about these remedies? Keep reading then. You will find everything that you need to know about dry mouth and natural remedies for it below.
Drink A Lot Of Water
The most common cause of dry mouth is dehydration. When your body does not get enough water, it tries to send you the message in its own ways. Dry mouth is also one of the ways in which your body might try to send you the message that it is not getting enough water intake. So, if you are facing this condition lately, then you should definitely increase the amount of water that you are taking daily.
Suck On Sugarless Candies
The next thing that you can do to cure the condition is to suck on sugarless candies. Although this is not the permanent solution to the problem, it Continue reading
Introducing HCX 4.0: Migration Event Details and Estimation, In-Service Upgrades, and more
VMware HCX is indeed a swiss army knife — a mobility platform with several options to streamline and optimize workload migrations between on-premises and VMC-based environments. HCX delivers secure, seamless app mobility and infrastructure hybridity across vSphere 6.0 and later versions, both on-premises and in the cloud. Thousands of customers worldwide use HCX for faster, safer, and large-scale migrations, cost-savings, and efficient operations.
Today, we are excited to announce an important milestone in this journey — HCX 4.0, a major release that introduces new functionality and enhancements. This release focuses on providing enhanced visibility, reducing service downtime during upgrades, and simplifying the reconfiguration of NSX security policies post-migration.
Let’s take a look at some of the new capabilities in HCX 4.0:
New Release Versioning and Lifecycle Policies
Starting with the HCX 4.0.0 release, HCX is switching its naming convention from ‘R’ releases to Major.Minor.Maintenance semantic versioning to align with VMware convention. VMware HCX will now use X.Y.Z.P where:
- X is a major version.
- Y is a minor version.
- Z is a maintenance version.
- P is a patch version. This is a unique bit that uses the build number.
Please also note that the VMware N-2 Lifecycle Policy will be applicable with the new convention, providing extended support and additional flexibility to customers.
Each Major or Minor release will have a minimum support duration of 12 months (*).

Day Two Cloud 086: AWS Succession – Does It Matter Who’s The Next CEO?
AWS needs a new CEO now that Andy Jassy has been tapped to run the Amazon mothership. Does the cloud giant need a high-powered, Type-A successor to drive AWS's growth, or is it now so dominant that a ham sandwich could run the company? That's the topic for discussion on today's Day Two Cloud podcast.
