META'S NEW LLM-BASED TEST GENERATOR IS A SNEAK PEEK TO THE FUTURE OF DEVELOPMENT

Meta has created a system called TestGen-LLM that automatically generates test cases. These test cases are filtered down until there are only cases that are verified to both work and improve test coverage of the code base. The system shows how LLMs can be used to create more reliable software by helping find and catch non-obvious edge cases in code. It also shows how LLMs can be effectively used within large codebases and what the future of software testing may look like.

USING LOCALSTORAGE IN MODERN APPLICATIONS

localStorage has been supported in most browsers for over fifteen years, so it’s a reliable way to persist key-value pairs on the client side. This article explores the various aspects of the localStorage API, its advantages and limitations, and alternative storage options available for modern applications. localStorage is best used for user preferences, simple settings, or temporary data. It should not be used for large datasets, querying data, or frequent read/writes as there’s JSON overhead and it’s not asynchronous.

TELL HN: TO BE HONEST... GPT COPILOTS AREN'T THAT GREAT FOR PROGRAMMING (HACKER NEWS THREAD)

Some programmers are finding GPT-based copilot tools useful for generating simple code, like boilerplate or unit tests. However, many others say they're not good tools due to inaccuracies or irrelevant code. Programmers may have mixed opinions on GPT-based programming tools, but they all agree that the accuracy of suggestions needs to be better.

INTERVIEWING ENGINEERS FOR DIAGNOSTIC SKILLS

SREs and backend engineers need strong troubleshooting skills, but these are rarely assessed during traditional interviews. To effectively test for these skills, create an interactive role-playing exercise where candidates work through a complex bug. This approach focuses on evaluating the candidate's diagnostic process rather than simply finding a solution. It tests key skills like their ability to differentiate between relevant and irrelevant information, the specificity of their questions, how they handle dead-ends, and their overall problem-solving strategy.

HOW CHATGPT IS MAKING ME LAZY

ChatGPT can streamline development tasks, making developers potentially over-reliant on it. The chatbot helped this author remove local download functionality in the Cloudflare D1 beta. Despite initial setbacks, they used ChatGPT to iteratively develop a script solution, starting with JSON to CSV, then TSV, and finally a direct import to a local SQLite database.

PHIND-70B

Phind-70B is a free LLM model that beats the latest GPT-4 Turbo on certain benchmarks. It is specifically made for fast code generation and is meant to be used by developers.

INTRODUCING SUPERMAVEN, THE FIRST CODE COMPLETION TOOL WITH A 300,000-TOKEN CONTEXT WINDOW

Supermaven has introduced a new code completion tool that boasts an unprecedented 300,000-token context window for a deeper understanding of any codebase. The tool provides AI suggestions tailored to a codebase's specific APIs and coding conventions, even with large or unique projects. The model was trained on edit sequences rather than just files, making it well-suited for refactoring tasks.

FROM TO DB

Create forms directly from your Postgres, MySQL, or MSSQL database.

LARGE LANGUAGE MODELS ARE DRUNK AT THE WHEEL

The current hype around LLMs like ChatGPT risks obscuring the actual limitations of the technology and could potentially foster a counterproductive boom-and-bust cycle within the tech industry. While LLMs excel at producing human-like text, they cannot reason, understand truth, or autonomously solve problems. They are also prone to hallucinations (i.e., they lie) and unpredictable behavior. Despite this, businesses are rushing to integrate LLMs in often unproductive ways.

IT’S OFFICIAL, APPLE KILLS WEB APPS IN THE EU

Apple has confirmed that it is intentionally removing Home Screen web app installation in the EU, claiming that it is necessary for compliance with the Digital Markets Act (DMA). However, the decision directly circumvents the DMA. Apple's actions are probably prompted by its fear of losing control over app distribution and the associated revenue.

GO RUN

Go's 'go run' command allows developers to compile and run code without external build tools or complex setups. This is unlike JavaScript, where project structure and build tools can vary wildly, introducing dependencies and potential complexity. Standardized build systems have made the Go developer experience a positive one.

CANVAS SIZE

Canvas Size is a JavaScript library that helps determine the maximum area, height, width, and custom dimensions of an HTML canvas element.

EXPANDING OUR PARTNERSHIP WITH GOOGLE

Reddit has partnered with Google to make its archive of conversations and communities more discoverable, improving content accessibility for Reddit users while expanding Google's training data for product and service improvements.

INCIDENT REPORT FOR FEBRUARY 21ST, 2024

Resend experienced a 12-hour-long outage because a developer accidentally dropped the entire production database.
