Reducing Memory Usage in Ruby
I’ve been working on building a compacting garbage collector in Ruby for a while now, and one of the biggest hurdles for implementing a compacting GC is updating references. For example, if Object A points to Object B, but the compacting GC moves Object B, how do we make sure that Object A points to the new location?…

Why is Rust difficult?
Rust is considered difficult to learn by many people. Indeed, when I learned it, I considered it to be the hardest programming language up to that time I’ve met. And that says something, since I have a habit of learning whatever language I find interesting. Looking back, I’m not sure I was correct, C++ is probably…

Brushing up on operating systems and C programming
If you were like me in college, you first learned about the C programming language in an introductory computer science course. Then, perhaps you took a really hard course in operating systems. Then, y

JEP 325: Switch Expressions
Extend the switch statement so that it can be used as either a statement or an expression, and that both forms can use either a "traditional" or "simplified" scoping and control flow behavior. These changes will simplify everyday coding, and also prepare the way for the use of pattern matching (JEP 305) in switch …

Keep Webpack Fast: A Field Guide for Better Build Performance
webpack is a brilliant tool for bundling frontend assets. When things start to slow down, though, its batteries-included nature and the ocean of third-party tooling can make it difficult to optimize. Poor performance is the norm and not the exception. But it doesn’t have to be that way, and so — after many hours of…

Fast base64 encoding and decoding
Computers store data as streams of bits. Binary files like image, audio or video files are allowed to contain just about any sequence of bits. However, we also often use text formats; for example, web pages and emails are required to be text. So how do we send images by email? How do we embed … Continue reading…
