I’ve been obsessed with simulation toys (software that allows you to play with a complex miniature world) ever since I was young and playing with SimCity and cellular automata. This kind of software exists at the delightful and weird intersection of simulation, complexity science, education, and gaming. And I want more of it! I created Microcosm Industries to initially act as a clearinghouse for simulation toys that are being built, ones that allow the user to playfully grapple with complex syst

The AC culture wars may be solved by advances in environmentally friendly technology.

In the near future, AI -powered surveillance systems will be able to track everything we do in public, and much of what we do in private. And if we do something wrong—shoplift, litter, jaywalk, you name it—the system will notice, retain it, tie it to your official government record, communicate that fact to you, and provide real-time alerts to any relevant authorities… and maybe also to the general public. Think of these systems as automated speed cameras, but on steroids. Only they’ll enforce not just speed limits, but any other rule you can imagine. And you won’t receive a ticket weeks later by mail; you’ll be informed about and fined for your violation immediately...

Last month, Polestar shocked the auto industry when it announced that it was pulling out of the US. The EV company's decision came after the federal government denied its authorization to continue selling its cars despite a rule banning vehicles with Chinese-made connected vehicle software.

Meta is in breach of the EU's Digital Services Act (DSA), a preliminary investigation has found, over the "addictive" design of Instagram and Facebook. It's likely to be forced to redesign both apps and could face a fine of up to $12 billion. The European Commission said Meta "did not adequately assess the risks of […]

Introduction If you have been building applications using Vite, you are likely used to a specific workflow: write React components, bundle them with esbuild/Rollup, and serve a single HTML file that fetches a large JavaScript bundle. In this world, everything is a "Client Component." However, as the React ecosystem shifts toward the App Router and React Server Components (RSC), the architecture is fundamentally changing. For developers moving from a Vite-centric mindset to a Next.js framework, the biggest hurdle isn't the syntax—it's the mental model. In this guide, we will break down the core differences between Server and Client components and how to adapt your Vite-based habits to this new reality. The Vite World: Single-Page Application (SPA) Default In a standard Vite + React project, your entire application lifecycle happens in the browser. The browser requests the page. The server sends a nearly empty index.html . The browser downloads the JS bundle. React hydrates the app, fetches data from an API via useEffect , and renders the UI. While this is excellent for developer experience (DX) and highly interactive dashboards, it often leads to "Layout Shift" and slower "Time to Interactive" for content-heavy pages because the client has to do all the heavy lifting. The Shift: Thinking in "Environment Splits" With React Server Components, the paradigm shifts from "Everything happens on the client" to "Compute where it makes sense." 1. What are Server Components? By default, in the Next.js App Router, every component is a Server Component. These components execute only on the server . They never send their code to the client-side bundle. This allows you to: Access backend resources directly: You can query your database or file system inside the component. Keep secrets safe: API keys and sensitive logic stay on the server. Reduce bundle size: Large dependencies (like a markdown parser or date library) stay on the server and only the resulting HTML is sent to the user

One common issue on WordPress websites with a large number of posts is that the Rank Math XML Sitemap can become slow to load. This happens because the sitemap is generated dynamically every time a visitor or search engine bot requests it. A simple solution is to use a static sitemap cache , allowing the web server to serve pre-generated XML files directly without executing PHP for every request. This significantly reduces server load and improves crawling performance. Benefits of Using a Static Sitemap Using a static sitemap cache provides several advantages: Faster sitemap loading times. Lower CPU and PHP worker usage. Improved crawling efficiency for Google and other search engines. Ideal for websites with thousands or even millions of URLs. Reduced server load when search engine bots frequently request sitemap files. 1. Setting RankMath Sitemap Cache The first step is to enable static sitemap generation using the Rank Math Sitemap Tweak plugin. The plugin automatically creates static copies of your XML sitemaps and stores them in the following directory: /wp-content/uploads/rank-math/ Instead of generating the sitemap dynamically through WordPress, your web server can serve these static files directly. 2. Configure Apache (.htaccess) If your website is running on Apache , add the following rules to your .htaccess file. # ========================== # XML cache # ========================== RewriteCond %{REQUEST_METHOD} GET RewriteCond %{QUERY_STRING} ^$ RewriteCond %{HTTP:Cookie} !wordpress_logged_in RewriteCond %{DOCUMENT_ROOT}/wp-content/uploads/rank-math/%{HTTP_HOST}%{REQUEST_URI} -f RewriteRule ^(.*)$ /wp-content/uploads/rank-math/%{HTTP_HOST}/$1 [L] These rules check whether a cached sitemap file exists. If it does, Apache serves the static file immediately without loading WordPress. 3. Configure Nginx If your server is using Nginx , add the following configuration inside your server block. # # Static cache # location / { try_files \ /wp-content/uploads/rank-

GitHub has made the redesigned GitHub Copilot CLI terminal interface generally available. It adds a tabbed layout for sessions, gists, issues, and pull requests; an in-session, form-driven setup for MCP servers, skills, and plugins that avoids hand-editing config files; and a cleaner, theme-aware, more accessible UI with screen reader support.

After a 1-on-1 meeting with my supervisor, one interesting point stuck in my head: he mentioned that he balances his main work with side projects. He said these projects give him energy. I’m curious: what are your side projects or activities that recharge you and help you perform better at work? submitted by /u/AstinAshler [link] [留言]
