Open source SEO platform on Rails
The HateFreeWeb.org just open sourced a new SEO platform that detects hate speech, phishing scams, E-mails that where exposed in hacks, accessibility issues, mobile issues and more. As we thought “you are who you link to” (and Google thinks so too!), we pay special attention to problems on sites you are linking to. This means that if you link to a site that has phishing links on it, you enable crimes without knowing it. It’s a very useful tool for web designers, software developers and every business that runs a website. It’s all on GitHub! Happy forking and let’s make the Internet a safer place:) https://www.hatefreeweb.org

Why the standard CSV library author deserves our hugs and thank yous
Hello, I’ve written a new episode in the why the csv standard library is broken, broken, broken (and how to fix it). It’s a new introduction to the series titled “I apologize - Sorry, Sorry, Sorry.” to clarify that I am in no way blaming the author (really I’m blaming YOU :-), that is, all the free-loaders waiting for a miracle. The author or the authors of the standard CSV library deserve our hugs and thank yous for the great work and many hours (for sure many unpaid and volunteered) put into the CSV library. We are all standing on the shoulders of giants. Thank you. Thank you. Thank you. Cheers. Prost.

Detecting hate speech and derogatory language
I just published a gem that connects to our hate speech detection API. We use it to analyze websites our clients link to, to ensure they don’t accidentally link to hate speech sites etc and ruin their reputation. You send text in and it sends the polarity back: 1 = hateful, 0 = nothing detected Super useful to protect schools, business websites etc. Hatefreeweb on Rubygems
csvreader v1.0 - read comma-separated values (csv) the right way (incl. hash, ...)
Hello, I’ve uploaded version 1.0 of the new comma-separated values csvreader library / gem that lets you read tabular data in the comma-separated values (csv) format the right way :-), that is, the basic methods such as Csv.read or CsvHash.read use best practices out-of-the-box with zero-configuration. Under the hood the new library includes purpose-built “backend” parsers (e.g. ParserStd, ParserStrict, ParserTab, etc.) so you can handle
all the popular comma-separated values (csv) formats / dialects such as MySQL (use Csv.mysql.read) or PostgreSQL (use Csv.postgres.read) exports and more using unix-style escapes and \N or unquoted empty values for null/nil and so on. Data is the new gold :-) Happy data / gold mining with the new csvreader library / gem (in ruby). Cheers. Prost. PS: What’s wrong (broken) in the standard csv library? See the let’s count the ways article series.
I am writing an introductory book to Rails application deployment

To Microservice or Monolith, that is the question...
The constant series of questions asked about if so and so or such and such should be better architected as microservices, or built with multiple layers of front end components hitting backend dohickies hosted within multiple layers of auto-magic hosting “silos” of data and services, shows that truly, there is way too much confusion out there on what constitutes a “good” software development approach.
