Although the techniques described below won't be very popular nowadays (after all, why bother using C if we're going to write object-oriented code?), they are still quite relevant for embedded systems and other low-level things (kernel development, etc). For example, lots of Linux Kernel subsystems use similar…
Longer answer: it depends on what you mean by "equivalent". Pointer arithmetic and array indexing are equivalent. In other aspects, pointers and arrays are different.
Scheme's numbers are not like the rest of its library. They're older, and they're mostly borrowed from other languages (Maclisp and Common L...
I gave the best programming interview answer I may have ever given last Friday. The interviewer hauled out FizzBuzz and asked me to solve it. It took me a minute to stop laughing. FizzBuzz is a brain-dead simple programming problem, used pretty much to tell if a developer has a pulse at all. It is…
In my attempts to learn the C programming language well enough to write my own C compiler , I've encountered some very interesting examples of C syntax that you generally don't see every day. All of these examples you'll see here will compile without warnings or errors even with very strict compiler flags in gcc and…
The first computer I used had about 2KB of RAM. The other day, I compiled a 2KB Common Lisp script into a 16MB executable to get its startup (and total execution) time down from 2s to subjectively instantaneous — and that didn't bother me the least, for my current computer has 8GB of working memory…
This is a quick Friday blog post to talk about a recent experience I had working on a piece Juju code that needed to capture the data being sent over a net.Conn .
Closures in Rust are powerful and flexible, building on traits, generics and ownership.
Go is decidedly polarizing. While many are touting their transition to Go, it has become equally fashionable to criticize and mock the language. As Bjarne Stroustrup so eloquently put it, “There are only two kinds of programming languages: those people always bitch about and those nobody uses.” This adage couldn’t be…
Thoughts about programming, mostly
Given a string, get a truncated string of length up to 12. The task is ambiguous, as it doesn't say anything about whether or not 12 shou...
The above is the Hello World program for Java, arguably one of the most popular programming languages. Encapsulated in the above three lines are several different concepts ranging from static functions to return types to stdout and to the entirety of object oriented programming in general.
This piece is about how to build a modern web application with Common Lisp in the backend, from scratch.
I did it. It wasn't easy, but I did it. My C Compiler can compile itself. Even though it still has holes in functionality and obvious bug...
In February I open-sourced a library called Specter , and in my own work it has become by far my m...
An example of a monadic programming in Scheme that juxtaposes Haskell code for a state monad with the corresponding Scheme code.
Monad is a design pattern used to describe computations as a series of steps. They manage side effects in pure functional languages but can also be used in other languages to control complexity.
