weighted-word-mapping leetcode problem in Java ⚡

Dario and @AnthropicAI tonight... Nobody will notice a little rename, right?

Claude Fable 5 has been out for a couple of days. Some projects people have already built with it:

💡Java: Avoid public fields. Use private fields with getters/setters for encapsulation. #Java #OOP

Whole day gone on my Android project 🥰 Time flies when you’re coding! 😂

Spring Security in 30 lines — form login basic auth role-based access, explained. ☕☕ #CtrlPlusCode #Java #SpringBoot

Keep your code readable and spend less time parsing text 📝 Build clear code by keeping it short for local scopes, dropping repetition, and omitting variable types from the name.

❤️‍🔥Aspect-Oriented Programming (Spring AOP) 🍀🍀 Spring AOP allows you to intercept method calls and execute custom logic before, after, or around the actual method, without touching the method's code. #CtrlPlusCode #Spring #Java

We look at common scenarios in which final fields are mutated through reflection and what alternatives exist for each of them. Since these scenarios can appear in frameworks, libraries, and applications, this article addresses developers of all such projects. 🤝 social.ora.cl/6014BBdzYr

❤️‍🔥Want to master JPA/Hibernate basics? Let's break down the Core Annotations every Spring Boot developer must know @Entity, @Table, @Id, @GeneratedValue, @Column, @Enumerated #CtrlPlusCode #Java #SpringBoot #Hibernate

🚨 ANTHROPIC JUST PUBLISHED A 36-PAGE SECURITY GUIDE THAT BASICALLY TELLS YOU TO STOP TRUSTING YOUR OWN AI AGENTS. If you run agents on Claude Code, MCP servers, or automation tools, pay attention. The attack timeline has collapsed. AI models compress the gap between a vulnerability and a working exploit from months to hours, for mere dollars. Agents introduce new autonomous risks, from tool poisoning to context memory manipulation. The most useful idea in the guide is Anthropic's new security test: Does a control make an attack impossible, or just tedious? Automated attackers have unlimited patience. They will grind straight through friction like rate limits and 2FA. To defend at the speed of AI, you need hard barriers and automated defensive operations. Here is how Anthropic says you should lock down agents: → Treat static API keys as compromised. Use short-lived tokens that expire in minutes. → Apply "Least Agency": explicitly limit what each tool can DO. → Sandbox agents that process untrusted inputs like emails and web pages. → Scope permissions dynamically per task, not permanently. I've added the link to the guide in the 🧵↓

🛑Stop hardcoding API keys & configurations in your Java classes! It’s a recipe for security risks and deployment headaches. Instead, use Spring Boot's @Value annotation to pull data dynamically from application.properties. #CtrlPlusCode #Java #Spring

2. Prototype Scope, You do not want them sharing the same instance. #CtrlPlusCode #Java

1. Singleton Scope (The Default) all two services are sharing the same count variable. #CtrlPlusCode #Java

Stop mixing up Spring Bean Scopes ☕️ • Singleton (Default): Like a shared Google Doc. One instance reused everywhere. Best for stateless services. • Prototype: Like a downloaded Word doc. A fresh instance created every single time. Best for stateful data. #CtrlPlusCode #Java

Looping through a Java list twice to get two different results? Use Collectors.teeing() (Java 12 ). It acts like a T-pipe for streams: splits one dataset into two separate calculations (like Min & Max), then merges them at the end. One pass. Clean code. ☕️ #CtrlPlusCode #Java

Still writing 50 lines of Java boilerplate just to hold data? Java Records fix this in one line Behind the scenes, you instantly get: • Constructor • Getters • toString() • equals & hashCode Immutable & clean. #CtrlPlusCode #Java #Coding
