Building a Functional Expression Language within C's Type System

Andrew’s Substack • 0 implied HN points • 30 Oct 24
🕹 Technology Programming Software Systems Development Engineering
  1. LM is a functional expression language that can generate code for different targets, including cross-compilation.
  2. To integrate LM with C, we need to convert LM types into C types, handling memory alignment and other details carefully.
  3. C's expression capabilities allow us to construct new data types and perform complex operations using simple expression syntax.

Understanding How C Strings Are Stored in the Data Section of a C Program

Andrew’s Substack • 0 implied HN points • 24 Oct 24
🕹 Technology Programming Software Systems Development Coding
  1. Strings in C are arrays of characters that end with a null character. When you define a string, it gets stored in a specific part of the computer's memory.
  2. String literals are placed in a read-only section of memory, meaning you can't change them. Trying to change a string literal can cause your program to crash.
  3. Global and static strings can be changed because they're stored in a writable section of memory. This allows them to keep their values throughout the program's run.

Programming in C with an Assembler…

Andrew’s Substack • 0 implied HN points • 22 Oct 24
🕹 Technology Programming Software Computing Development System Design
  1. C is good for cross-platform development and handles important tasks like memory management well. This makes it easier for programmers to write efficient code.
  2. LM introduces modern programming features to C, like function templates and object-oriented programming styles. This can help make coding simpler and more powerful.
  3. The focus of LM is to tackle complex tasks that are hard in other languages, making it a valuable tool for systems programming. This means programmers can do more with less effort.

Generics vs Templates in LM Programming

Andrew’s Substack • 0 implied HN points • 15 Oct 24
🕹 Technology Programming Software Languages Development Coding
  1. Generics are about type erasure, which means when a general type is used, the specifics are lost. This can limit what you can do with that type unless you define its constraints.
  2. Templates are used for code generation, meaning they create specific versions of functions for each type used. This allows for more flexibility and can enable complex operations like comparisons.
  3. Zig and C++ use templates for parameterized types, which helps create specialized functions only when they are needed. This can make programming more efficient.

Lambda Mountain v1.17 Patch Notes

🕹 Technology Software Programming Development Computing Engineering
  1. The v1.17 update enhances programming experiences with new features, making the software more user-friendly. It focuses on improving performance significantly, allowing for optimized code structures.
  2. This patch includes useful improvements like single instruction math operations, function inlining, and better project organization, which help streamline coding processes.
  3. Overall, the update promises a strong foundation for future enhancements and supports more efficient coding practices, which is essential for low-level programming.

Six Billion Unnecessary Function Calls

Andrew’s Substack • 0 implied HN points • 10 Oct 24
🕹 Technology Programming Software Optimization Development Engineering
  1. Focus on adding features before trying to optimize your code, unless performance is a big issue. It's better to develop first and deal with optimization later.
  2. Low-level optimizations are useful for compilers, but many developers may not gain much from them. It's often smarter to enable existing optimizations like `O3` for better performance.
  3. High-level optimizations, like rethinking your code structure, help everyone. They improve performance and make the code easier to understand.

useEffectEvent

Andrew's Substack • 0 implied HN points • 15 Oct 24
🕹 Technology Software Development Programming Web Frameworks
  1. The 'useEffectEvent' hook lets you use values in an effect without causing the effect to rerun when those values change. This helps keep your code clean.
  2. You can currently manage values with refs or by excluding them from the dependency array, but both ways can be clunky or raise warnings.
  3. Using 'useEffectEvent' simplifies handling non-reactive values, making your code easier to read and maintain.

😎 Insights on Workbench UI Latency, Version Control Evolution, Open Source AI & More

ppdispatch • 0 implied HN points • 29 Oct 24
🕹 Technology Programming AI Software Development Open Source
  1. Writing code that is easy to delete can reduce maintenance costs. It helps to avoid complex dependencies and treat code as a temporary fix rather than a permanent solution.
  2. Netflix found that a slow UI in JupyterLab was caused by an overloaded resource-monitoring extension. They learned to analyze everything methodically to find the root cause of tech issues.
  3. Jujutsu is a new version control system that aims to be faster and simpler than Git. It focuses on improving merge conflict resolution while still allowing compatibility with Git repositories.

Retrieval Augmented Generation in Practice: Building Search for Connected Notes

Nick Savage • 0 implied HN points • 21 Nov 24
🕹 Technology AI Software Development Data science Machine Learning
  1. Retrieval Augmented Generation (RAG) helps software retrieve information and generate new ideas using special numbers called embeddings. This makes searching for connected notes easier and more powerful.
  2. Chunking and reranking improve the quality of search results. By breaking down text into smaller pieces and reassessing them, users can find more relevant information quickly.
  3. Zettelgarden's graph structure has potential for creating deeper connections between notes. This could lead to more meaningful insights, not just basic search results.

Use bad standards

CodeFaster • 0 implied HN points • 28 Nov 24
🕹 Technology Blockchain Software APIs Development Standards
  1. ChainId is a confusing standard in crypto, but it is universal, which makes it easier to use across different applications. Instead of creating custom names for chains, sticking with chainId saves development time.
  2. Creating custom standards can complicate things, as you might have to map your data to fit different APIs. This can lead to a lot of extra work for developers.
  3. Even if a standard seems bad, if everyone else uses it, it often makes more sense to stick with that standard to avoid unnecessary complications.

Making minimalist chatbot iOS app so I don't have to pay $20/mo for premium LLM subscription

Expand Mapping with Mike Morrow • 0 implied HN points • 06 Dec 24
🕹 Technology Software Mobile Apps Chatbots AI Development
  1. If you use a chatbot a lot every month, paying a flat fee like $20 is worth it. But if your usage is unpredictable, it might be cheaper to use LLM APIs instead.
  2. Many chatbot apps ask for your API key, which can feel risky since your data could be misused. Building your own chatbot app can help you feel more secure.
  3. The author's app is very simple and needs to be more user-friendly. They are looking for better, secure chatbot apps for iOS that don't require a subscription.

Trying Is a Way to Learn How an API Works

The API Changelog • 0 implied HN points • 19 Dec 24
🕹 Technology APIs Software Development Programming Web
  1. Trying out an API rather than just reading about it helps you learn faster. You get to interact with it and see how it works in real-time.
  2. A safe space, like a sandbox, is essential when experimenting with APIs. This way, you can play around without affecting real data or making costly mistakes.
  3. Having tools like browser-based clients or simple forms makes it easier for users to test APIs. It encourages more people to try your API, which is crucial for attracting new users.

The bottleneck in programmer productivity is not the number of lines that he writes.

Getting Job Done - oriented programming • 0 implied HN points • 30 Dec 24
🕹 Technology Programming Software Productivity Development Coding
  1. A programmer's productivity doesn't depend on how many lines of code they write. It's really about how many lines they can understand.
  2. Writing a lot of code can be easy, but if it relies on external libraries that a programmer doesn't fully understand, it can lead to many bugs.
  3. Understanding the code you work with is key. If you grasp the code and its surrounding architecture, you can debug and develop much faster.
