Por Raquel Sánchez Guirado. Enlaces que aparecen al final del vídeo: https://linktr.ee/lapencadev https://forms.gle/EZrCgME4XnsnGYbB6 Soy políglota: hablo español, inglés, un poquito de alemán y de francés, Java, Typescript, HTML y CSS (Sí, HTML y CSS también son lenguajes). En esta charla nos sumergiremos en el fascinante cruce entre dos mundos aparentemente dispares: la filología y la programación. Como filóloga inglesa pero actual desarrolladora fullstack, quiero compartir mi perspectiva distópica y exponer las similitudes que encuentro entre el lenguaje humano y el lenguaje de programación. Desde la importancia de la comunicación hasta la comparativa sintáctica, semántica y lingüística, revelaré cómo ambos mundos se entrelazan. Abordaremos la evolución de los idiomas y cómo la capacidad para trabajar con varios lenguajes de programación es similar al concepto de “políglota” en términos lingüísticos. Concluiremos reflexionando sobre cómo la diversidad de lenguajes potencia la creatividad y la resolución de problemas en el desarrollo de software. 📅 Programa completo: https://t3chfest.es/2024/programa

Por Rafael Bermúdez Míguez y Alicia Laguna Tellez. Implementar principios teóricos en software del mundo real es complejo. Muchas veces surgen dudas o no hay casos prácticos documentados. En ZARA también nos enfrentamos a ello. No tenemos una solución mágica pero podemos compartir lo aprendido. Partiremos de un subconjunto funcional con el que todos estamos familizarizados (la gestión de stock de un ecommerce) e iremos aterrizando capacidades apoyándonos en la teoría: Estableciendo el Bounded Context y sus límites, la arquitectura y comunicación entre microservicios, el tratamiento que queremos hacer del dato o la modularización del código. Un ejemplo Java friendly que podrás trasladar a tu contexto. 📅 Programa completo: https://t3chfest.es/2024/programa

Hablamos de nulabilidad en Kotlin, o cómo manejar los valores nulos de manera segura. Para evitar lo que se conoce como "el problema de los mil millones de dólares", debido a los costos asociados con errores de referencia nula en sistemas de software a gran escala. También vemos cómo Kotlin aborda este problema con un sistema de tipos que permite distinguir entre tipos que pueden contener valores nulos y aquellos que no pueden. Viendo cuál es la interacción entre Kotlin y Java en cuanto a null pointers, prestando especial atención a cómo Kotlin introduce características de null safety para mejorar la robustez del código y reducir la probabilidad de errores de referencia nula al interoperar con código Java que no tiene tales garantías de seguridad.

Por José Miguel Moreno. Minecraft es un videojuego de mundo abierto en el que los jugadores pueden hacer cualquier cosa, siempre que esté dentro de los límites del juego. Pero, ¿cómo hacer algo para lo que el juego no ha sido programado? ¡Programándolo tú mismo! En esta charla aprenderemos a crear mods para servidores de Minecraft usando Java. Y ya puestos, que sea algo difícil: un mod para poner imágenes GIF animadas dentro del mundo. La charla se basa en un caso real (Yamipa) y en las dificultades técnicas que surgieron durante su desarrollo. 📅 Programa completo: https://t3chfest.es/2024/programa

Recientemente se ha propuesto un reto a la comunidad: Procesar lo más rápido que puedas 1.000 millones de registros ("1 billion" en inglés). El reto se conoce como "One Billion Row Challenge (1BRC)", y consiste en cargar el dataset de mediciones de temperatura para determinar la medición mínima, media, y máxima de cada ciudad. Cada línea consiste en una tupla de ciudad y temperatura separada por ";" como por ejemplo: "Hamburg;12.0". A tener en cuenta: - Hay 413 ciudades - La longitud de los nombres de ciudad varían entre 3 y 26 bytes - Las temperaturas pueden ser negativas, 1 o 2 enteros, y siempre con 1 decimal El reto se propuso inicialmente en la comunidad Java, pero han salido implementaciones en otros lenguajes de programación como Rust o C#. En el directo analizaremos algunas de estas soluciones junto con Antón Rodriguez, Principal Software Engineer en New Relic, con más de 10 años de experiencia en el ecosistema Java. Ya estuvo en el canal mostrando las novedades de Java. ﹤🍍﹥ Enlaces ├ 🎥 Suscríbete: https://youtube.com/c/CodelyTV?sub_confirmation=1 ├ 🔖 Cursos: https://bit.ly/cursos-codely ├ 🔗 Material relacionado: | ├ https://www.youtube.com/playlist?list=PLZVwXPbHD1KMIm7aTAlatIIxEomU_TAiD | ├ Optimizaciones JVM: https://docs.google.com/forms/d/e/1FAIpQLScn7SCsXVwT3AzwNpXVhjWtkb2kr8mDVCAU5Qtg18nOU9ppzg/viewform | ├ Post original (Java): https://www.morling.dev/blog/one-billion-row-challenge/ | ├ Repo principal: https://github.com/gunnarmorling/1brc | ├ Post .Net (C#): https://hotforknowledge.com/2024/01/13/1brc-in-dotnet-among-fastest-on-linux-my-optimization-journey/ | ├ Post Rust: https://curiouscoding.nl/posts/1brc/ | └ Otros lenguajes: https://github.com/gunnarmorling/1brc/discussions/categories/show-and-tell └ 👋 Redes sociales: ├ https://twitter.com/CodelyTV ├ https://twitter.com/antonmry ├ https://twitter.com/JavierCane ├ https://instagram.com/CodelyTV └ https://linkedin.com/company/codelytv
