• 2025.06.11 in #725 Learning Perl - File Handles
  In programming file processing is a key skill to master. Files are essential for storing data, reading configurations, and logging information. A file handle is a reference to an open file, allowing you to read from or write to that file.
• 2025.06.12 in #725 Learning Perl - Overloading Operators
  An operator in programming is a symbol or keyword that performs a specific operation on one or more operands (values or variables). There are many types of operators, such as arithmetic operators (like +, -, *, /) and comparison operators (like ==, !=, <, >). In Perl, you can overload these operators for your own classes, allowing you to define custom behaviour when these operators are used with objects of that class.

• 2026.01.18 in #756 Doubly: Why Arrays Aren't Always Enough
  Robert explores when traditional arrays fall short and makes a compelling case for using doubly linked lists instead, especially for operations like O(1) insertions and intuitive cursor navigation. Through Perl examples and performance trade‑offs across multiple implementations, from pure Perl to thread‑safe C registries, the article highlights practical data‑structure choices and when they pay off.
• 2026.01.25 in #757 Ready, Set, Compile... you slow Camel
  An excellent writeup on the process of optimization. Basically saying: don't do what you don't have to. This is specifically about optimizing OOP systems in Perl. Feel free to comment either on the bpo version of the article or here.
• 2026.03.29 in #766 Horus, Apophis, and Sekhmet: An C/XS Identifier Stack for Perl
  This post focuses on three related XS modules for efficient and high speed unique identifier creation (UUID, ULID and deterministic) and content-addressable storage in Perl. It provides a comprehensive overview of how to use these tools in conjunction with each other to create an efficient and scalable unique ID workflow. It also demonstrates how they can be used together.
• 2026.03.29 in #766 Eshu: Indentation Fixer for Eight Languages, Written in C
  This article discusses a portable C-based program that formats code and will uniformly line up the indentation across eight different programming languages. It describes examples to show you how Eshu can help you make the indentation to your programming code consistent with very little effort and no extra heavy duty tools required. For Developers who choose to use other than traditional language-specific formattors, this document presents an overview of how Eshu creates a lightweight formatting solution that developers may find useful.

  "Chandra is a Perl module that lets you build cross-platform desktop applications using the web technologies you already know - HTML, CSS, and JavaScript - while keeping your application logic in Perl.". Sounds interesting to see where it goes.
• 2026.04.07 in #768 Heap::PQ
  Priority Queue is a top performing C extension for binary Heaps written in Perl and can outperform pure Perl by an astonishing 55 times. The purpose of this article is to document the features of Heap's Priority Queue: Versatile APIs (procedural functional as well as traditional OO) and specialised NV Heaps that minimise the overhead of SV creation/maintenance and increase the throughput of C doubles (represented as raw C doubles).
• 2026.04.08 in #768 LRU::Cache
  Robert presents LRU::Cache, a high-performance cache for Perl written in XS that achieves O(1) performance on the caching layer for Perl. Using an OP-optimised functional API that avoids method dispatch for the standard Perl OOP model; this module is capable of achieving 5-20 x faster than pure Perl alternative caches, making it an ideal choice for your performance-critical applications.
