Simplifying ipSpace.net Products
When I started my ipSpace.net project life was simple: I had a few webinars, and you could register for the live sessions. After a while I started adding recordings, subscriptions, bundles, roadmaps (and tracks), books… and a few years later workshops and online courses.
As you can imagine, the whole thing became a hard-to-navigate mess. Right now you can buy almost 70 different products on ipSpace.net. Time for a cleanup.

It strikes me as odd to see a developed and, by any reasonable standard, a prosperous economy getting into so much trouble with its public communications policy framework.Technology with Purpose: Vashkar Bhattacharjee’s Story
In honor of today’s International Day of Persons with Disabilities, we are sharing part one of Vashkar Bhattacharjee’s story. He is the National Consultant, Accessibility, A2i, Prime Minister’s Office of Bangladesh, and the Program Manager, Young Power in Social Action (YPSA).
I am Vashkar Bhattacharjee, a visually impaired person from Bangladesh. And this is the story of how I have excelled in life and career, not through sympathy and charity, but through inspiration and assistance.
In Bangladesh, every 1 in 10 persons experience at least one kind of disability. I am one of approximately 4 million Bangladeshis who are visually impaired.
In 1979, like most of the villages in Bangladesh, my village in the district of Chittagong did not have doctors or hospital facilities. On July 1st in the same year, in a small remote village called Bagdondi, I was born in my parental home without any medical supervision. Right after my birth, I was bleeding through my nose and mouth. My parents and relatives could not figure out what was wrong. After a while, the bleeding stopped and everything seemed to be normal. By the time I was two years old, my parents realized the heartbreaking truth that Continue reading

Diptanshu Singh wrote a nice explanation of the math behind reliability calculations. Definitely worth reading even if you hated statistics.
A Dummy Light for My Network
I’ve always heard the red lights in car dashboard referred to as Dummy Lights. One example might be the use of a light to indicate high temperature in lieu of a temperature gauge. Over the past few weeks, I’ve spent more time doing unique things with hardware and software. Yesterday I challenged myself to build an indicator light to show health issues with my Meraki MX.
Before I get into this, the cool factor here is not what I have built. The cool factor is that someone with very little experience, driven by curiosity, can build this in a very short period of time. I’m neither a professional developer nor someone with deep knowledge around hardware hacking. So before I get too deep into this, I want to solicit thoughts, feedback, and recommendations.
The Trigger
After a little research, I found that the Meraki Dashboard provides a “Load Monitor” that is returned via a perfScore value. This feature is in beta and there’s not a lot of information on it. Therefore, consider your own data source that you would like to use as a trigger value. The following python code will store a numeric value (score) between 1 and 100 (with a Continue reading

Interoperability between Dell and Cisco: Rapid-PVST+
Today I am going to talk about the PVST+ as many of you already know. PVST+ is the advance version of PVST and stands for the Per VLAN spanning Tree Plus. As the name suggest you can have the you are creating STP for the VLANs. So if you have 3 VLANs in your network you have 3 different STP instances per VLAN in your LAN network.
Before I start with the PVST+ ,I would like to tell you guys that we have our own youtube channel for various network videos that can further help you guys to study further. I will going to add many more videos soon on the channel, Please subscribe to the channel for the study network related videos

Here today I am taking an example where i am taking Cisco and Dell switches in a LAN network and we are going to check the interoperability between the Cisco and Dell.
Below is the sample network topology showing the Cisco and Dell switches

There’s an “automation meteor” headed right at us, according to financial adviser and Reformed Broker blogger Josh Brown, who used this troubling “chart o’ the day” from Wharton to show just “how quickly things have changed” over the past decade. And how they’re going to keep on changing. —Shawn Langlois @ MarketWatchThere’s an “automation meteor” headed right at us, according to financial adviser and Reformed Broker blogger Josh Brown, who used this troubling “chart o’ the day” from Wharton to show just “how quickly things have changed” over the past decade.

Many historians believe that one of the main reasons why the U.S. won the Cold War was its decisive lead over the Soviet Union in computer and telecommunications technology, which, by the 1980s, made it virtually impossible for the Soviets to compete, either economically or militarily.
