One thing that’s always bugged me about the whole “You’ll be out of a job in 5,10,15 years if you don’t learn programming” is this. Who cares when you’ll be OUT OF A JOB? It’s like we’re driving a car in dense fog, trying to figure out when to perfectly apply the brakes so that we don’t go over a cliff that’s SOMEWHERE in the distance. Like - the fact that we’re even having this debate is a horrible waste of time in my opinion.Alexa , AWS Lambda & AWS IOT MQTT and you can interact with anything
I hear a lot on IOT but don’t have a clue on underlying protocols. My interest is only to understand how it might help a business or more than that my personal interests. So continuing the server power on/off series I wanted to do it with Amazon echo voice command. Now, this is not a smart power switch where you can power-on with a command on Echo but you actually have to send a message to IDRAC, we already covered this in a previous post.
Well, the main goal isn’t to power-on a server that can be done manually as it sits beside me, the main goal is to extend this to any business / personal ideas which might get the benefit.
Summary – Develop a small interactive model to understand Alexa voice service / AWS lambda and MQTT so that we can get a feel of what can be achieved with this.
I will not go much into any tech explanations or bore you with English, I will put here two screenshots and code to git, hopefully, you should be able to give it a try.

Failure Analysis: An Interesting way to Break CAPWAP
I recently stumbled into what I think is a very interesting failure scenario with a Cisco Wireless solution. This was a traditional controller based solution that leveraged a CAPWAP data and control plane. The symptoms were fairly consistent and strange.
Symptoms:
- When issues are occurring, all uploads reduce to about 1.5Mb/s
- Installing a new AP seems to solve the issue
- Issue re-occurs in a few minutes
- Issues only occur for one specific site
- Wireless is configured consistently across 5 sites
- RF is not an issue
Topology:
When I got involved with this, a few people had reviewed the configuration and TAC had been involved for some time. While on-site, I took a look at RF and channel utilization (expecting to find it to be ugly since I knew it was heavily dependent on 2.4Ghz). My first order of business was to spin up a test AP in its own group and advertise a test SSID on a 5Ghz channel. Upon doing so, both iPerf and Speedtest were >50Mb/s. My initial thought was that the density needed to be increased and the radios tweaked to get more clients on 5Ghz. However, a few minutes into my testing–my upload also Continue reading
Intent-Based Networking Resources
Every now and then I get a question along the lines of I’m your subscriber and would like to know more about X, so I decided to start creating technology-specific pages on www.ipSpace.net that would include links to most relevant ipSpace.net blog posts, webinars, sections in our online courses, and interesting third-party resources.
The subscriber triggering this process asked me about Intent-Based Networking, so here’s the relevant resources page.
