It's officially winter, so what could be better than drinking hot chocolate while querying the new Stack Overflow dataset in BigQuery? It has every Stack Overflow question, answer, comment, and more - which means endless possibilities of data crunching. Inspired by Felipe Hoffa's post on how response time varies by tag, I wanted to look at the comments table (53 million rows!).

This is a game built with machine learning. You draw, and a neural network tries to guess what you're drawing. Of course, it doesn't always work. But the more you play with it, the more it will learn.

One glaring constant in your career is that the technology you'll use for your craft will regularly change. When this happens you have a choice: hold on to what you know or become an early adopter, exploring the next thing. It's the early adopters who take the early lead towards mastering the newest tools will have a greater chance of wining the race for new client opportunities.

There are multiple vulnerabilities in ImageMagick, a package commonly used by web services to process images. One of the vulnerabilities can lead to remote code execution (RCE) if you process user submitted images. The exploit for this vulnerability is being used in the wild.

Refactor until you feel you are one step behind the solution you want. Avoid your comfort zone. And while you might see extractions that would probably get you to a better design, don't apply them until you see the need two or three different times. Remember that duplication is cheaper than the wrong abstraction. The best refactors will then naturally arise from the repeated inconveniences, instead of from unbacked ideas of what could potentially be better.

A list of Ruby gems that have memory leaks

Matz is experimenting with three concepts that may or may not be included in Ruby 3.0. 1. Man-machine collaboration through a static analyzer (e.g. rubocop or ruby-lint) that uses soft typing (i.e. inferred typing) to determine if a program will crash or not. 2. Performance enhancements through JIT compilation, but preliminary implementations have shown to increase memory consumption as a side effect. 3. Concurrency improvements through better abstractions like streams and pipelines. When used, the running program would place itself inside an event loop, disable the GIL, and force objects to be immutable. Matz calls it Rube Goldberg Programming.

As of today, all support for Ruby 1.9.3 has ended. Bug and security fixes from more recent Ruby versions will no longer be backported to 1.9.3.

has_many is an anti-pattern which leads straight to monolithic applications. However, a simple inversion can free us from its grasp. What is the first model you added to your application? Probably User, right? So, once you wrote user.rb and its corresponding tests, and committed it - why did you ever open that file up again to tell it about something that it did not need to know existed? Rails keeps you from reopening user.rb if you add a column to the User table, and this is good, right? So why, when you added a Posts table far away, did you open up User again to make it aware of Posts? Did the definition of being a user change? Did you did not realize you were violating the Open-Closed Principle, one of the 5 principles of SOLID design? Somewhere inside I bet you knew it felt dirty to keep opening up User and making it aware of things that it had been blissfully unaware of.
