Learning to Read x86 Assembly Language - Pat Shaughnessy
Writing assembly language is something best left for the experts. To write code that runs directly on your microprocessor you need to know how memory segmentation works, what the intended use of each register is, how codes executes in real and protected modes and much, much more. And, of course, modern compilers will usually produce faster, more optimized code than you ever could, without making a
Need a Second Opinion on Your Ruby Code? Ask Crystal - Pat Shaughnessy
Running the Crystal compiler on your Ruby code is like asking a second doctor for their opinion. When it comes to your health, you don’t hesitate to get a second opinion. Doctors don’t always agree, and a second doctor’s appointment is always time well spent when it comes to staying healthy. But what about your code? A code review is similar to going to see a doctor: Someone examines your code, lo
Exploring Ruby’s Regular Expression Algorithm - Pat Shaughnessy
According to Wikipedia, Oniguruma means “Devil’s Chariot” in Japanese We’re all familiar with regular expressions; they are “the developer’s swiss army knife.” Whatever sort of information you need to find, whatever sort of text you need to parse, there’s always a way to do it using a regular expression search. In fact, you’ve probably been using regular expressions for much longer than you have b

A Rule of Thumb for Strong Parameters - Pat Shaughnessy
It can be hard to open the Strong Parameters door and let permitted values into your Rails 4 app. Last week I banged my head against the wall for a few hours trying to figure out how to whitelist input values for my Rails 4 app using the Strong Parameters feature. Calling permit when you have a simple attributes hash for a single new object is straightforward, but figuring out how to call permit f
How Big is a Bignum? - Pat Shaughnessy
Ruby represents small integers using Fixnum and large integers using Bignum. Most of us don’t use Ruby to perform complex calculations for science, engineering or cryptography applications; instead, we might turn to R, Matlab or some other programming language or tool for that sort of thing. When we calculate values using Ruby, it’s often to process simple values while generating a web page using
Ruby Under a Microscope - Pat Shaughnessy
Everyone knows that Ruby is a powerful language. Its dynamic nature allows you to concisely write the code you need to actually solve a problem instead of burying yourself under mountains of boilerplate. You don't have to fight it; you just get to enjoy the ride. But how is the magic created? And can you trust it? After all, MRI is written in C - a statically typed, compiled language which is pret
