Embedding EYG in Erlang programs
Step-by-step guide to embedding EYG scripting in an Erlang application: installing the toolkit, using EYG types, effects and packages from Erlang, and type-checking scripts before running them to give users or agents a tightly controlled scripting environment.

John Earnest's Beyond Loom tutorial uses Hershey vector fonts to teach Lil, Decker's APL-influenced scripting language: points, strokes, and paths as nested lists, then layout and drawing primitives for 2D vector text and shapes.

Composite objects and C++26 the std::polymorphic type
Marius Bancila explains C++26's std::polymorphic, the companion to std::indirect for owning polymorphic members in composite classes, covering value semantics, copying, and how it simplifies strategy objects, AST nodes, and similar has-a hierarchies.

Parser CombinatorsBetter than regex!
A hands-on TypeScript introduction to parser combinators: starting from a partial parser type, chaining parsers with sequencing and mapping, and building up a hand-rolled combinator library that parses real ping output into structured data, as a cleaner middle ground between regex and tree-sitter.

Abner Coimbre describes how he writes modern C in late 2026 after C23: naming, headers, types, error handling, and the conventions he kept from older 'How I Write C' guidance while adopting new language features.

Types of types: Haskell's Kind system
A practical tour of Haskell’s kind system—values, types, kinds, higher-kinded types and data, and custom kinds—drawn from adding typed configuration to a Redis clone.

C++26 Contracts: Introduction to Preconditions and Postconditions
C++ Stories introduces C++26 contracts: pre() and post() on function declarations and contract_assert() inside functions, why they beat assert, the ignore/observe/enforce/quick-enforce evaluation semantics, compiling examples with GCC, const parameters in postconditions, avoiding side effects in predicates, predicate cost, and why contracts are not a replacement for input validation.

hitogata describes rainbows, a specification for memory-mapped devices (console, arithmetic, disk, date/time and screen) attached to the ok stack-based virtual machine, turning it into a fantasy computer, with the memory layout of each device and open design questions.

Axel Magnuson shares techniques for abstraction in Zig, comparing comptime duck typing and interfaces with vtables against a trait pattern inspired by OCaml modules, then building trait helpers and trait functors on top of it.

C++26: the new debugging header
Sandor Dargo explains C++26's new <debugging> header from P2546R5 and P2810R4, which standardizes what projects like Boost.Test, Catch2, Dear ImGui and Unreal each reinvented: std::breakpoint, std::is_debugger_present and std::breakpoint_if_debugging, replacing platform-specific breakpoint macros.

ArenaAllocators don't play nicely with ArrayLists
Karl Seguin explains why growing a Zig ArrayList backed by an ArenaAllocator can waste memory: an arena can only reclaim or resize the most recent allocation, so interleaved allocations force the list to copy into new memory and strand the old buffer, using up to about three times the memory, and he suggests pre-sizing lists and avoiding interleaved allocations.

Adding Go's defer to the TypeScript Compiler
Andrew Healey forks the Go-based TypeScript compiler to add a Go-style defer statement, walking through how the compiler is structured, how defer should behave including error handling, and the JavaScript it emits, before concluding defer probably should not exist and that TypeScript's using declarations are the closer fit.

Full Haskell-like Type Class resolution in Java
Gabriel Garcia re-implements Haskell-style type classes in pure Java: using reflection and generics to parse static types, unify them, and automatically resolve instance witnesses, then extends the approach to higher-kinded types, context instances and overlapping instances, with worked examples like Show, Monoid, Traversable and Monad.

TypeScript and Haskell: Unions & Singletons
Gabriel Garcia explores how TypeScript's combination of union types and literal (singleton) types gives APIs precision, then tries to reproduce the same pattern in Haskell with type families, unboxed sums and singleton naturals, showing where the encodings get awkward and why they fail to behave like a set of types.

Language Interoperability From the Ground UpOriginal article link with an AI-written directory summary
A bottom-up explanation of how code written in different languages can work together. Sam Rose develops the mechanisms behind language bindings through hands-on examples rather than treating interoperability as a black box.
