Satellite system engineers consider the narrow beams (which lend themselves to frequency reuse) and high data rates of Ka band channels attractive for communication systems [Khan 2]. As a result, the satellite community witnessed a great increase...

Data Scientists need skill and experience to create useful Machine Learning (ML) models. ML activities include tool selection, training logistic decisions (move data to training vs. train in-situ), data acquisition, data cleaning, data quality...

Good Vs. Evil - Two Opposing paths Taken by a Similar Genius This blog post provides a comparison between Henry David Thoreau's Walden and Ted Kaczynski's Unabomber Manifesto. To compare these two works, I use both a modern Natural Language...

NFTs provide an immutable record of ownership for digital assets, verified by the global Ethernet Blockchain. The Blockchain tracks ownership of NFTs until the end of human civilization. 2021 ushered in speculative mania in every conceivable...

Rarible enables artists to mint, sell and trade one-of-a-kind digital collectibles in the form of Non Fungible Tokens (NFT). The Ethereum blockchain records the provenance of each NFT in a secure, distributed ledger that will last until the end...

Non Fungible Tokens (NFT) allow collectors to own unique, scarce digital assets. NFT protocols record ownership and provenance on the Ethereum Blockchain. Recent offerings from Jack Dorsey, Logan Paul and Lindsey Lohan helped fuel the current...

I started my AI/ML journey in 2011 with a laptop model, a term which indicates a measure of size. Laptop models, by definition, do not exceed the compute, memory and storage resources of a single piece of hardware. The laptop model approach works...

Model optimization on traditional Artificial Intelligence and Machine Learning (AI/ML) platforms requires considerable Data Architect expertise and judgement. These ML platforms require the Architect to choose from dozens of available training...

In this demonstration we continue to use Keras and TensorFlow 2.3 to explore data, normalize data, and build both a linear model and Deep Neural Network (DNN) to solve a regression problem. Today we use Principal Component Analysis (PCA) to...

In this demonstration we will use Keras and TensorFlow 2.3 to explore data, normalize data, and build both a linear model and Deep Neural Network (DNN) to solve a regression problem. TensorFlow Core 2.3 includes tf.keras, which provides the high...

Introduction Network Engineers use the OpenDaylight (ODL) platform to craft, deploy and manage interesting virtual network services. Internet Service Providers, Cloud Service Providers, Data Center Engineers and Academics use ODL to address the...

The Amazon Web Services (AWS) Elasticsearch service provides GROUP BY operations via the aggregations, or AGGS, Application Programming Interface (API). GROUP BY and AGGS operations provide syntax to collapse rows with similar values into summary...

Operational document stores require backups for disaster recovery and data migration. Elasticsearch uses the term snapshot for their backups. Amazon Web Services (AWS) provides a fully managed Elasticsearch service that includes both automatic...

Elastic Architects designed the distributed Elasticsearch platform to follow NoSql principles. In the traditional Relational Database Management System (RDBMS) world, SQL databases use GROUP BY syntax to group rows with similar values into...

In this HOWTO, I will describe the process to connect an Ubuntu EC2 instance to the Amazon Web Services (AWS) provided Elasticsearch Service via the boto3 Python library. This blog updates my incredibly popular original post on this topic which...

Introduction FastAI provides Jupyter notebooks to wrangle data, train models, optimize models and then serve models. I recommended FastAI to my Data Scientist friends and they found the FastAI Jupyter layout and workflow both cumbersome and...

This blog post describes how to configure Flask to emit form data to your own personal Gmail account. You don't need to use Gmail, in fact, you can configure Flask to send data to any email account you have access to. This architecture uses...

InfluxDB provides an exciting Time Series database with tons of industry momentum and enthusiasm behind it. InfluxData, the parent company that distributes the product overhauled the classic InfluxDB service with their new InfluxDB 2.0 offering....

Fastai provides helper functions on top of Pytorch to help us wrangle, clean, and process data. In this HOWTO we will accomplish the following: Deploy an AWS g3.8xlarge instance Compile and install NVIDIA drivers on our g3.8xlarge instance Use a...

In this blog post you will deploy your own personal Kraken terminal using the InfluxDB Cloud 2.0 platform. With this terminal you can quickly filter data, plot data and apply math. The first section provides a Hello World project to get up and...

Flask, Lambda, API Gateway, IAM and S3 enable massively scalable web database applications. Flask provides a simple, Pythonic Model View Controller (MVC) framework to develop the application logic. Lambda and API Gateway provide pay-per-use...

I've previously discussed the Reduced Coloumb Energy Neural Net algorithm on this site. I wrote the algorithm in Matlab, which uses index based logic to select, filter, wrangle and process data. I thought it would be a fun exercise to refactor...

I deployed my first web database application back in 2002 thanks to the seminal O'Reilly book Web Database Applications with PHP and Mysql by David Lane and Hugh E. Williams. In the past sixteen years, the industry developed tons of frameworks...

Over the air communications, such as text messages, satellite radio, walkie talkies and WiFi need to deal with the unpredictable effects of noise in the channel. Coding theory attempts to make noisy channels more reliable by bringing the noise...

Engineers face the reality of imperfect and noisy channels when designing digital communication systems (DCS). The engineers must account for signal degradation to ensure that a receiver receives the message that the transmitter intended. The...
