Goal You can run the Ruby code on a modern browser like Google Chrome. Try to press "Run Ruby" button. Observe the behavior of method func1 and define a method answer1 that performs the same behavior as func1. # You can call `func1` p func1(0) #=> 1 p func1(1) #=> 2 p func1(2) #=> 3 # Can you tell how `func1` is defined? # Hint: def func1(n) = n + ??? # Define `answer1` that works like `func1` def
The Janet Programming Language
Janet is a functional and imperative programming language. It runs on Windows, Linux, macOS, BSDs, and should run on other systems with some porting. The entire language (core library, interpreter, compiler, assembler, PEG) is less than 1MB. You can also add Janet scripting to an application by embedding a single C source file and a single header. Use Cases Janet makes a good system scripting lang
Announcing D1: our first SQL database
We announced Cloudflare Workers in 2017, giving developers access to compute on our network. We were excited about the possibilities this unlocked, but we quickly realized — most real world applications are stateful. Since then, we’ve delivered KV, Durable Objects, and R2, giving developers access to various types of storage. Today, we're excited to announce D1, our first SQL database. While the w

Lambda Diagrams
Lambda Diagrams are a graphical notation for closed lambda terms, in which abstractions (lambdas) are represented by horizontal lines, variables by vertical lines emanating down from their binding lambda, and applications by horizontal links connecting the leftmost variables. In the alternative style, applications link the nearest deepest variables, for a more stylistic, if less uniform, look. The

LISP with GC in 436 bytes
SectorLISP now supports garbage collection. This is the first time that a high-level garbage collected programming language has been optimized to fit inside the 512-byte boot sector of a floppy disk. Since we only needed 436 bytes, that means LISP has now outdistanced FORTH and BASIC to be the tiniest programming language in the world. SectorLISP consists of 223 lines of assembly. It provides a LI
SectorLISP Now Fits in One Sector
Update: Please read our most recent SectorLISP v2 announcement: LISP with GC in 436 bytes The SectorLISP project has achieved its goal of creating a LISP that's tiny enough to fit in the master boot sector of a floppy disk. To the best of our knowledge, this is the tiniest LISP to date. Since a master boot record is only 512 bytes, that means LISP is now tied with FORTH to be the most lightweight
