Natural language processing for Node.js


Tags big-data data-science machine-learning robotics

An article by Jordan Irabor about processing unstructured textual data using Natural language processing for Node.js.

Natural language processing (NLP) is a subfield of linguistics, computer science, information engineering, and artificial intelligence concerned with the interactions between computers and human (natural) languages, in particular how to program computers to process and analyze large amounts of natural language data.

Modern computer systems can make sense of natural languages using an underlying technology called NLP (natural language processing). This technology can process human language as input and perform one or more of the following operations:

  • Sentiment analysis (Is it a positive or negative statement?)
  • Topic classification (What is it about?)
  • Decide on what actions should be taken based on this statement
  • Intent extraction (What is the intention behind this statement?)

The article then takes on the NLP journey:

  • Prerequisite and installation of natural library
  • Tokenization – demarcating and possibly classifying sections of a string of input characters
  • Stemming – refers to the reduction of words to their word stem
  • Measuring the similarity between words (string distance)
  • Classification – also known as text tagging is the process of classifying text into organized groups
  • Phonetic matching

.. and much more. All the code is included and available in this GitHub repo. Also plenty of links to further reading.

Do you know what's in Helm 3?


Tags kubernetes devops containers cicd web-development

Understand new capabilities and migration options for Helm 3, the package manager for Kubernetes. By Martin Hickey on IBM Developer Blog.

Helm 3 is one of the most eagerly anticipated releases for the last year or so. This latest version of Helm, the package manager for Kubernetes, is now available.

The excitement for this release was heightened by the promise of removing Tiller, the in-cluster component of Helm that interacted directly with the Kubernetes API server to install, upgrade, query, and remove Kubernetes resources. However, Helm 3 goes far beyond removing Tiller.

New capabilities in Helm 3:

  • Client only architecture
  • XDG base directory specification
  • No need to initialize Helm
  • Release storage changed
  • Modifications to charts
  • Chart repository status
  • Improved release upgrade strategy
  • Simplified CRD support
  • Helm test framework updates
  • Helm 2 interface still supported
  • Helm Go library overhauled
  • Other changes

… each of this is described in detail in the article. There are a lot of new capabilities worth trying out in Helm 3. Give it a go!

Going serverless with OpenFaaS and Golang -- The ultimate setup and workflow


Tags golang serverless containers apis

Martin Heinz put together this article on building serverless OpenFaaS application with Go. OpenFaaS which is open source Function as a Service tool for developing cloud-native serverless applications.

You will learn how to setup (IMHO) the ideal project and workflow for developing OpenFaaS functions, as well as creating your first function using Golang.

You might be asking, why - out of all the frameworks like AWS Lambda, Google Cloud Run, OpenWhisk etc. - would I choose OpenFaaS?

  • No Vendor-Lock
  • Cloud Native
  • Any Language
  • Performance

To run the functions we need a cloud environment and considering that we will be using local machine, we should probably choose the most lightweight option possible, here author will use Ranchers k3s (alternatively you could also use KinD).

The article then dives into detailed steps how to build your own version of OpenFaas and your first Go function, including set up, unit tests, automation with Taskfile for function deployment, simple CI/CD. Excellent!

Why everyone working in DevOps should read the Toyota way


Tags learning agile teams management devops

Ian Miell wrote this essay about Toyota’s way. The Toyota Way is a set of principles and behaviors that underlie the Toyota Motor Corporation’s managerial approach and production system.. His advice is simple: Ignore the noise, go to the signal.

Once author started reading The Toyota Way, he realised that it was the real deal, and was articulating better many of the things I’d done to make change in business before.

One of the most obvious objections to anyone that foists The Toyota Way (TTW) on you is that its lessons apply to manufacturing, which is obviously different from a knowledge industry. How can physical stock levels, or assembly line management principles apply to what is done in such a different field?

The author points out that the book explains:

  • The Toyota Way is a philosophy, not a set of rules
  • Waste and pipelines are universal
  • How flow is not achieved: Failure to ‘Go and See’

Some excellent points done in this review. A rather shocking amount of time can be spent in knowledge industries producing information that doesn’t get used. Fantastic!

How to buy the right CPU: A guide for 2019


Tags apps miscellaneous learning open-source

Matt Safford wrote this guide for tomshardware.com about choosing CPU for your PC. Whether you’re building or upgrading a PC, the processor matters a lot. We’ll help you choose the right one for your needs.

Higher clock speeds and core counts can make a major difference in overall performance, providing a snappier system, smoother gameplay and faster completion of intensive tasks such as video editing and transcoding.

Plus, the CPU you choose will also dictate your motherboard options, as each processor only works with a specific CPU socket and set of chipsets.

This article will guide you through:

  • AMD or Intel: Which Should You Get?
  • What do you want to do with your CPU?
  • What generation CPU do you need?
  • How do you read the model names and numbers?
  • Should you overclock?
  • What are the key CPU specs and which should I care about?
  • What do you need more: clock speed, cores or threads?
  • What socket does my motherboard need for this CPU?

You can’t lose with AMD or Intel: For mainstream users, so long as you’re considering current-generation parts (AMD Ryzen 3000 or Intel 9th Generation Core), this debate is basically a wash. Nice one!

The Hows, Whats, and Whys of Elixir Telemetry


Tags web-development programming erlang elixir

“What gets measured gets managed.” This quote – wrongly attributed to Peter Drucker – tells us that when we monitor information about something, we can make decisions about what it is we’re monitoring and where to go next. An article about monitoring in Elixir by Samuel Mullen.

The article deals with:

  • The Value of Monitoring
  • Lies, Damned Lies, and Vanity Metrics
  • Getting Started with Telemetry

Telemetry is a library giving us a dynamic dispatching library for metrics and instrumentations.” It’s a simple library providing a standardized interface for capturing and handling metrics from monitored events.

Telemetry isn’t a revolutionary idea and the maintainers don’t claim it is. What they do claim is that it provides a simple and flexible means for capturing data. Good read!
