Welcome back! In part 4 we went over the nitty-gritty of lambdas and how to store them, we explored the relation between the various C++ algorithms and containers, plus we took a stroll through some non-standard containers with exceptional capabilities. Note: part 1 is here. In this probably final part 5, we’ll be…
Update: Since this post was written, Go 1.11beta2 has been released. I’ve updated the setup section to reflect this. Russ Cox kindly wrote to me to explain the reasoning behind storing the Go module cache in $GOPATH . I’ve included his response inline.
How I wrote GoAWK, how I tested it, and how I measured and improved its performance.
If I were more musically talented I would be writing a song ♫ Arguments that are destructured, and operator characters combine-ed; Loop binding changes and convert redefine-ed… ♫ no none of that, please stop.
Before we dive into the technical details, let’s start with a quick history lesson, courtesy of Don Syme who worked on adding generics to .NET and then went on to design and implement F#, which is a pretty impressive set of achievements!!
A case study on how compilers decouple components from each other using data.
Why you should consider using F# for your next project
There are a lot of places you’ll see * and ** used in Python. These two operators can be a bit mysterious at times, both for brand new programmers...
This is an article about compiler directives; or as they are commonly known, pragmas. It’s derived from a talk of a similar name that I gave last year at GopherChina in Shanghai.
In this post we’ll explore Haskell’s kind system, the similarities between types and kinds, and show how these can be leveraged to write safer and more reusable code.
This is a tutorial on building your own shell using Rust, in the spirit of the build-your-own-x list. Creating a shell is a great way to understand how the shell, terminal emulator, and OS work together.
The Visitor Pattern is one of the most mis-understood of the classic design patterns. While it has a reputation as a slightly roundabout technique for doing simple processing on simple trees, it is actually an advanced tool for a specific use case: flexible, streaming, zero-overhead processing of complex data…
This document comes with a companion example program, available as one file or as multiple files (zipped) .
This is an essay I wrote early-2016. After battling with soundness vs. usability in Typed Clojure for many years, I was starting to reconsider the “obviously wrong” approach of baking unsoundness into the type system from the get-go. I look at some historical examples of intentional unsoundness in type systems, and…
Chris Lattner, the architect of the Clang/LLVM C compiler explained the effects of the C standard’s “undefined behavior”(UB):
Emacs 26.1 was recently released . As you would expect from a major release, it comes with lots of new goodies. Being a bit of an Emacs Lisp enthusiast , the two most interesting new features are generators ( iter ) and native threads ( thread ).
Sketches of Elixir : Friends, I am now at least in this respect a rare breed: an Elixir programmer who has never written Ruby. I was never a professional Erlang programmer. I cut my teeth on Python
Before I start this post, let me preface it by saying that I’m not an experienced Rustacean by any means. The excellent foks at /r/rust gave a lot of helpful feedback and cleared up some misconceptions I had. Futher errata and corrections are appreciated. This post is aimed at helping other fledgling rust-learners…
How I finally decided what is better (for me), Lisp or Haskell?
A couple weeks ago, Galois and Immunant launched c2rust. Since I wrote one of the best-known C-to-Rust translation tools (Corrode), and since I worked for Ga...
So, given all of that, lets dive into the meat of the article. What are we going to accomplish in Clojure today?
GraalVM challenges the status quo on the JVM. This newly-released just-in-time compiler brings substantial speed improvements and support for polyglot applications. It also allows us to translate our JVM bytecode into small self-contained native binaries. In this session we’ll explore Graal’s impact on Clojure. We’ll…
This post discusses how maps are implemented in Go. It is based on a presentation I gave at the GoCon Spring 2018 conference in Tokyo, Japan.
