How do organizations approach and mitigate issues that lead to documented public cloud security incidents?
Streaming HTML sends HTML from server to browser in chunks as it is generated. It took a back seat as single-page applications became the standard, but it has become more popular along with server-side rendering. A clear advantage to streaming HTML is you can render something immediately to indicate to the user that something is happening and you can start downloading assets like CSS and JavaScript earlier while you wait for the more time-consuming parts of the response to be generated.
Engineering crits at Figma are collaborative sessions designed to foster brainstorming, knowledge sharing, and problem-solving early in the development process. Inspired by design critiques, Figma uses FigJam to facilitate asynchronous feedback, ensuring everyone’s perspectives are included in the conversation. Unlike traditional reviews, engineering crits emphasize suggestions over mandates.
Prisma is an open source ORM that allows you to easily manage and interact with databases. This guide discusses the features, benefits, and use cases of Prisma to help you decide if it’s the right choice for your next project.
There is a widespread disregard for front-end development within the tech industry. Frontend work is sometimes biased against as there are beliefs that frontend is less technical and thus, less valued. This devaluing of frontend work harms the quality of software products and limits the potential of the web.
To better estimate software projects, it’s helpful to break them down into smaller, well-defined tasks. This process starts with a high-level goal and iteratively expands tasks until they are clear enough for a developer to understand what needs to be done and how to know when it's complete.
Developers sometimes prioritize code perfection over delivering value to customers, leading to negative effects for both teams and customers. Teams should shift their focus to smaller, more frequent deliveries that provide immediate value to the customer, even if temporarily sacrificing some code quality. By breaking down large projects into smaller increments and limiting work-in-progress, developers can significantly shorten development cycles and have happier customers.

Goqite is a persistent message queue library built on SQLite and inspired by AWS SQS.
LLMs show potential for generating fuzzers to find bugs in code. A fuzzer is a program that automatically inputs semi-random data into a program or stack to detect bugs. While LLMs can find some software bugs through static analysis, results are often less reliable than traditional techniques due to false positives. As LLMs get better, they could be used to create targeted fuzzers to uncover vulnerabilities.
Some companies, like Midjourney, are using Google TPUs in production - they are hard to come by since Google themselves are using so many TPUs.
Refloat is an accurate float parser that is faster than standard float parsing libraries.
Bluesky, a decentralized X and Threads competitor, is offering grants to support developers building applications and tools on its AT Protocol.
A gallery of unique, creative 404 pages.
This blog explores the concept of using `infinity` within CSS, specifically in the `calc()` function, to achieve unique effects like ensuring an element has the highest `z-index`, creating extremely large elements, and dealing with browser inconsistencies. `infinity` is essentially shorthand for the largest possible value in a particular situation. This value can and will change between browsers, operating systems, and CSS properties. It can be used to create some pill shapes, hide content for screen readers, and make CSS animations.
Coroutines are functions that can be suspended and resumed while potentially passing data between suspension points. They are useful for implementing various patterns involving cooperation between different tasks or functions, such as asynchronous flows. This article demonstrates how to use coroutines to build a very flexible and simple abstraction for UI components, enabling you to split behavior and view into reusable bits, maintain internal state, and consolidate component lifecycles within a single location.
Astro is a static site generator that offers a robust development experience with TypeScript integration and built-in i18n/l10n support. Its static site generation conflicted with this developer's need for server-side locale negotiation, so they integrated a Rust web server (axum) to serve the Astro website, allowing for custom locale negotiation logic while still using Astro's advantages.
Databases often focus excessively on benchmark performance, overlooking the fact that a subjectively better user experience is often more important. The rate at which a database improves, ease of use, and how it integrates into existing workflows are all factors that can be more important when choosing a database over just raw performance. Focusing on a streamlined user experience that empowers quick analysis can sometimes offer a better edge than single-metric performance gains.
To write effective documentation, carefully choose what to document, focusing on common questions, poorly understood concepts, and information crucial for informed decisions. Understand your audience's knowledge level, tailor your language, and structure the documentation for easy navigation. Write with the future in mind by explaining the "why" behind decisions, linking to current information, and encouraging a culture of shared documentation ownership.
To make the most of a side project, start with a problem you face yourself and clearly outline goals. After that, iterate continuously and take in feedback from users honestly. The success of a side project doesn’t have to be defined solely by the money earned, but rather based on what is learned.

Google has published a whitepaper that outlines its "Secure by Design" approach, which advocates for the adoption of languages like Java, Go, and Rust to achieve high-assurance memory safety. Google has a massive C++ codebase. It will gradually adopt memory-safe languages for new code while seeking safety improvements for existing C++.
Amazon S3 is often thought of as a cloud-based file system, but it lacks important features of a traditional file system like partial overwrites. This mismatch in expectations has significant implications for software (especially databases) designed to work with filesystems as it makes them incompatible with S3. Despite this, S3 still is valuable due to its interface, high bandwidth, and low maintenance.
Git’s HEAD refers to your current location in the Git repository, indicated either by a branch name or a commit ID stored in the .git/HEAD file. HEAD can also be used as a command parameter ('git show HEAD') to reference the currently checked-out commit. Git often includes HEAD in its output (such as 'HEAD detached') to provide context about your working state within the repository.
