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...
Introduction OpenDaylight allows cloud engineers to programmatically deploy, configure and control virtual network services. As written on the OpenDaylight website, ODL helps Internet Service Providers, Academics and Cloud Service Providers to...
Introduction In this HOWTO, I will demonstrate a very quick and dirty method to transcribe customer service voicemails to text and emit the text to an Elasticsearch NoSQL document store. Once in Elasticsearch, you can search the voicemails for...
Introduction Machine Learning engineers use Probabilistic Neural Networks (PNN) for classification and pattern recognition tasks. PNN use a Parzen Window along with a non-negative kernel function to estimate the probability distribution function...
This blog post summarizes the first three chapters of Bernard Sklar's Digital Communication - Fundamentals and Applications textbook. Signals A Digital Communication System (DCS) transmitter (XMT) sends a waveform selected from a finite set of...
Introduction I investigate the effectiveness of a Reduced Coulomb Energy (RCE) Neural Network on the classification of the University of California, Irvine (UCI) Bupa liver disorder data set. I investigate seven (7) different versions of the data...
Introduction OpenDaylight provides a Software Defined Network (SDN) controller that allows network engineers to programmatically direct network services via a Representational state transfer (REST) Application Programming Interface (API). When I...
Part Two of this HOWTO demonstrates how to secure your S3 hosted website with HTTPS. If you haven't completed part one yet, be sure to click here. Once you complete this HOWTO, you will have a secure website, that Google approves, as seen in the...
This HOWTO demonstrates how to secure your Simple Storage Service (S3) hosted website via Hypertext Transfer Protocol Secure (HTTPS). While the S3 Representational State Transfer (REST) enpoint supports native HTTPS, an S3 bucket configured to...
I wrote this white paper a while back. This paper discusses the evolution from hierarchical to Flat IP Architectures for mobile networks. This information may be of interest to mobile network architects, especially in light of the emergence of...
In this HOWTO, I will demonstrate how to easily integrate the Google reCAPTCHA service into a Flask web application using Flask-WTF. The following cartoon depicts the end result. A Flask application server provides a simple (beautified) survey to...
In this HOWTO, we expand upon the simple Elasticsearch proxy we deployed in our first Lambda tutorial. In that tutorial, we showed you how to create a proxy in front of the AWS Elasticsearch service using a Lambda function and an API Gateway. We...
Introduction Last month, I followed the example of Full Stack Python and migrated this blog from Wordpress to Amazon Web Services (AWS) Simple Storage Service (S3). The S3 hosting approach gives me the following features: Global caching via...
From the land of Nintendo and Samurai comes Monacoin, a Japanese cryptographic currency based on Litecoin. If you look at www.coinmarketcap.com you will see that Monacoin increased about 30x in the past three months. I found it a bit challenging...
Caution! Math Ahead! For the Math-phobic, I explain how I crunch the test results in a math-free, simple and focused blog post here. I use math here, so this may be your last chance to escape! Still with me? Excellent! The bullets below outline...
Do you have big data chops? Quick, what do these three things have in common? Yankees, Giants, Rangers, Knicks What about these? Beatles, Monkees, Beach Boys Do you have an answer for each? "New York," for example, for the first list and "Rock...
All production databases require backups. The AWS Elasticsearch documentation states: Amazon Elasticsearch Service (Amazon ES) takes daily automated snapshots of the primary index shards in an Amazon ES domain... However, you must contact the AWS...
Freshlex LLC (should) architect the reliable multicast infrastructure for the putative John Carmack biopic, which will hit the Internet in December of 2018. The first blog post discusses two of the enabling technologies, FCAST and ALC. The second...
In this blog post I will revisit the first piece of code I wrote with the R Programming language, back in the early part of this decade. Coming from an Octave/MATLAB background, I really enjoyed the functional nature of R. I imagined flinging...
