If you've ever worked on an e-commerce project in Chile, sooner or later you bump into Transbank. There's no avoiding it. I built a reference template that use NestJS on the backend and Next.js 16 on the frontend, and in this post I want to walk you through the whole thing: what Webpay Plus actually is, why the integration looks the way it does, and how each piece fits together. Github Repository Reference: Link A bit of context Webpay Plus is one of the most important online payment methods in Chile. The user experience is straightforward: your customer enters an amount on your site, gets redirected to Transbank's branded payment page, fills in their card details there, and comes back to your site with a result. From a UX perspective it's not as slick as Stripe Elements or a fully embedded checkout — the user always sees Transbank's domain in the address bar during the payment — but from a developer's perspective that's actually a feature. You never touch card numbers. PCI scope stays minimal. Transbank handles 3D Secure, fraud rules, and bank routing. The trade-off is that the integration model is what you might politely call classical . It's built around full-page redirects and form POSTs, not modern APIs with JSON responses and webhooks. That's important to understand up front, because it shapes every decision you'll make in the code. The integration flow, step by step Before looking at any code, it helps to have a clear mental model of what's happening . There are three distinct moments where your system talks to Transbank's system, and each one has a specific shape. First Step: When the customer clicks "Pay", the backend asks Transbank to create a transaction (amount, order ID, return URL) . Transbank returns a transaction token and a redirect URL where you must send the user. Second Step: Transbank requires the redirect to be an HTTP POST with the token in a token_ws form field, so you must generate an HTML form with a hidden token_ws input and submit it prog

We are excited to announce the first alpha release of Arc, a lightweight, C-based programming language and interpreter designed for simplicity, performance, and educational clarity. Version Overview Version: v0.0.1-alpha Status: Alpha (Experimental) License: GPL-3.0 This initial release establishes the foundational pipeline of the Arc language, from lexical analysis to AST-based interpretation, featuring a robust set of core language constructs and a custom memory management system. Key Features Language Core Variable System: Declaration and updates using the VAR keyword. Functions: Support for custom functions (FN) with parameters and RETURN values. Control Flow: Conditional branching with IF, THEN, ELIF, and ELSE. Iterative loops with WHILE, FOR, and THEN. Loop control with BREAK and CONTINUE. Exception Handling: Graceful error recovery using TRY...CATCH blocks. Data Types: Integrated support for Numbers (Integers/Floats), Strings, Booleans, and Lists. Import System: Modularize projects by importing other .arc files using IMPORT. Syntax Highlights Case Sensitivity: Keywords (e.g., VAR, WHILE, IF) are case-insensitive. Identifiers (variable and function names) are case-sensitive. Operators: Comprehensive set of arithmetic (+, -, *, /, ^), comparison (==, !=, <, >, <=, >=), and logical (AND, OR, NOT) operators. Comments: Single-line comments starting with #. Built-in Standard Library I/O Operations: print, get_input, open_file, read_file, write_file, close_file. Data Manipulation: len_of, typeof, to_int, split_string, append_list, range. Math Library: A comprehensive math.arc providing constants (PI, E) and functions (sin, cos, tan, sqrt, log, etc.). Tooling & CLI Arc comes with a powerful CLI and an interactive REPL: Interactive REPL: Run code line-by-line with syntax highlighting. CLI Options --debug (-d): View tokens and AST tree during execution. --code (-c): Execute a string of code directly. --float-precision (-p): Control decimal output. --mempool-size (-m):

Excited to share SkillMap AI, a platform designed to help organizations make faster and more accurate staffing decisions. The idea is simple: project requirements and candidate profiles often live in separate documents, making team allocation slow and inconsistent. SkillMap AI bridges that gap by converting project requirements into structured skill demand and matching them against candidate capabilities. ✨ Key Features • Requirement Intelligence – Transform project briefs into normalized skill requirements • Candidate Matching – Compare resumes against actual project needs, not just keywords • Skill Gap Analysis – Identify missing capabilities before project execution • Staffing Decision Support – Recommend validation, interviews, and upskilling paths 📊 Outcomes ✓ Faster staffing shortlists ✓ Reduced manual resume screening ✓ Better project-team alignment ✓ Evidence-based skill gap identification ✓ Improved workforce planning 🌐 Live Demo: https://skill-map-ai-delta.vercel.app Would love to hear your thoughts and feedback!

Jo is a secure programming language that intends to addressing the fine-grained sandboxing problem at compile-time. To make secure programming practical it ends up with a two-world architecture : - confined world : not trusted, no FFI transitively, disciplined, standard library is not trusted - trusted world : trusted, FFI, type cast, language runtime is trusted The two-world architecture makes it possible to establish a security wall inside the language : that makes it easy to confine an untrusted program to arbitrarily fine-grained permission, e.g., only access certain rows or columns of a database table. The language-level confinement remove the need for runtime sandboxing because compile-time confinement is more fine-grained. It also makes security auditing easier. For resource quota, it still needs to be combined with ulimit/cgroups. We believe the two-world design addresses both the need for security and usability in secure programming. Comments are welcome on the design or alternatives to address the same problem. Link: https://jo-lang.org/security/two-worlds.html submitted by /u/liufengyun [link] [留言]
