Building an AI Assistant with Ollama and Next.js - Part 1
- Artificial Intelligence (AI) is transforming digital interactions, and creating a local AI assistant is now simple with Next.js, TailwindCSS, and Ollama, using models like Gemma 3:1B.
- Key tools used in the project include Next.js for React framework, TailwindCSS for styling, and Ollama for running open-source language models like Gemma 3:1B locally.
- Setting up involves creating a Next.js project, installing necessary dependencies, and running the app locally for development.
- With Ollama, running models locally is made easy; simply install and run Gemma 3:1B model within your terminal.
- Connecting the app to Ollama involves adding a simple API route that communicates with the local Ollama server through REST endpoints.
- Building the chat interface includes creating components like ChatInput, ChatMessage, and ChatPage to facilitate user interactions with the AI assistant.
- The chat interface allows users to send messages, receive responses from Ollama, and maintains a session for seamless interaction.
- Use of Ollama ensures privacy, speed, and cost-effectiveness by running everything locally, minimizing network latency and eliminating subscription fees.
- Future steps involve tighter integration with Ollama using ollamajs package directly in the codebase for enhanced functionality and customization.
- Overall, this approach provides a user-friendly and privacy-conscious method to build and interact with AI assistants, making it accessible for beginners and experienced developers alike.

How to Wait for Multiple Goroutines in Go
- In Go, the main goroutine often needs to wait for other goroutines to finish their tasks before continuing execution or exiting the program.
- sync.WaitGroup is commonly used for waiting for a group of goroutines to finish tasks.
- Example code demonstrates using sync.WaitGroup to synchronize multiple goroutines.
- Channels can be used for passing signals between goroutines to coordinate their execution.
- Context allows graceful control of goroutine exits and is useful for scenarios requiring cancellation or timeouts.
- errgroup is recommended as it combines WaitGroup functionality with error handling for waiting for tasks and handling errors.
- Using sync.WaitGroup is simple and efficient, but errgroup is more elegant and supports error propagation.
- time.Sleep is not recommended for waiting on tasks to finish as it lacks accurate synchronization compared to sync tools.
- Choose the synchronization method based on specific requirements such as error handling, cancellation, or number of tasks.
- Leapcell offers a serverless hosting platform for Go projects with multi-language support, cost efficiency, and scalability.

DRY — A Slippery Slope Toward Spaghetti-Land
- Consolidating logic for different types of vehicles can lead to decreased readability and maintainability.
- Blindly following DRY (Don't Repeat Yourself) principle without considering the purpose can result in potential issues.
- Copying and pasting code is not always a bad practice, especially when the logic is not serving the same exact purpose.
- Instead of focusing on avoiding duplication of code, it's important to ensure that the behavior is consistent and encapsulated properly.

SSR vs CSR vs SSG vs ISR in Next.js: Choosing the Right Rendering Strategy
- The article discusses Server-Side Rendering (SSR), Client-Side Rendering (CSR), Static Site Generation (SSG), and Incremental Static Regeneration (ISR) in Next.js.
- SSR involves initial HTML rendering on the server, leading to faster page loads, better SEO, and dynamic data.
- CSR renders initial HTML on the client, offering faster app load times, dynamic data, and improved user experience.
- SSG generates HTML and static assets at build time, ensuring fast page loads, improved SEO, and reduced server load.
- ISR re-generates static files after the initial build, providing improved performance, reduced server load, and dynamic data.
- Choosing the right strategy depends on factors like page load time, dynamic data needs, SEO, and server load.
- Ultimately, the appropriate rendering strategy varies based on specific application requirements and goals.
- By understanding these strategies, developers can make informed decisions for their Next.js applications.
- Cloudzilla offers tools and services for developers, aiding in app building and deployment in Next.js and other frameworks.
