According to a new site, 24% of the most popular websites in the world don't offer support for passkeys, which are considered the most secure way to log in to apps and services.

Open Graph images are the single biggest factor in whether your shared links look credible or broken. Yet most sites ship one generic image on every page because making a unique one by hand is tedious. Here is a more sustainable approach: treat preview images as generated data, not hand-made design. The problem, concretely When you share a link, the receiving platform reads your page's og:image meta tag and renders a card. If that tag is missing, points to a low-res logo, or is the same image on all 200 pages, your links look generic in every feed, Slack channel, and group chat. Studies of social sharing consistently show that posts with a clear, relevant preview image get meaningfully more engagement than those without. The reason teams skip it is not ignorance. It is friction. Opening a design tool, duplicating a template, swapping the title text, exporting at the right dimensions, and uploading the file takes 10 to 20 minutes per page. Nobody keeps that up across a real publishing schedule. So the back catalog stays bare and new posts get whatever the default is. The insight: it is template work Look at a typical preview card and ask what actually changes between pages. Usually just the title, maybe the author and a category tag. The layout, background, logo, and fonts are constant. That is the textbook definition of a job you should template once and generate programmatically, not redo by hand each time. How to solve it The cleanest pattern is to generate the image at build time or on first request, then cache it. Conceptually: // During your build or in an API route async function getOgImage ( post ) { const params = new URLSearchParams ({ title : post . title , author : post . author , tag : post . category , }); // Returns a ready Open Graph image URL return `https://getcardforge.dev/api/card? ${ params } ` ; } // In your page head // <meta property="og:image" content={getOgImage(post)} /> You can build this yourself with a headless browser plus an HTML templ

Every serious AI workflow eventually runs into the same failure. The agent does useful work in one session. It learns the shape of the project. It figures out which assumptions were wrong. It follows a correction, makes a decision, and gets closer to the real work. Then the session changes. The next run starts too cold. Old context comes back without the correction that changed it. The agent asks for the same setup again. It repeats an assumption that was already fixed yesterday. You end up managing the memory of the work instead of moving the work forward. That is the problem Pith is built for. Pith gives AI agents durable project memory they can trust when facts change. It is not trying to make an agent remember everything. That would be the wrong goal. Real projects are messy. Facts change. Decisions get reversed. A note that was useful last week can become stale after a release, a migration, a new customer constraint, or one correction from the human operator. The harder problem is not recall. The harder problem is knowing which memory is still useful. Why Longer Context Is Not Enough Longer context helps, but it does not solve continuity by itself. A long prompt can carry more text into a single run. It cannot automatically decide which prior facts survived a correction, which decision is now superseded, or which evidence should come back when the project resumes three days later. Developers working with agents already feel this. The friction shows up as small taxes: repeating project background that the agent should already know; re-explaining decisions that were already made; correcting stale assumptions that were already corrected; losing the reason behind a prior choice; restarting from a cold state after every meaningful break. Those taxes compound. The more serious the workflow, the more expensive the memory gap becomes. If an agent is helping with a toy task, forgetting is annoying. If an agent is helping with a codebase, a release, a customer workflow,

I just completed my bachelor’s last month and I have realised basic programming knowledge about different languages won’t get me any job. So I have decided to pursue Mern stack + Ai integration path. However I don’t have any money to buy courses. Lucky I have an internet connection and a laptop. I’m already familiar with basic javascript and I want to dive into the intermediate level at the least ASAP! Are there any free courses online for Mern ?? I’m already looking into freecodecamp. However if there are other unpopular options available, help would be appreciated. Thanks!! PS :- I attached google link cuz didn’t know what else to do. submitted by /u/Mental-Parsnip-8026 [link] [留言]

I couldn't find many resources online that showed how to see cache misses on macOS. I thought I'd learn a bit about Instruments, throw some toy problems at it, and write about the experience in a blog post. These toy examples - iterating sequentially then randomly, summing elements in a matrix, naive vs tiled matmul and iterating AoS vs SoA - are great to see some real numbers from L1 data cache misses, but they're far away from real programming problems. What's your experience using tools like Instruments/perf/cachegrind to actually optimize an algorithm? Is it ever needed to measure this at the hardware counter level or can you get away with intuition about the size of your data structure, how it's been accessed and using basic timers? submitted by /u/markuzo1 [link] [留言]

I spent some time reading Grafana Alloy’s source code to understand how it loads configuration, builds a dependency graph, evaluates components, and runs them. I wrote a short breakdown of what I learned, mainly focused on the runtime/controller, loader, scheduler, services, and component lifecycle. It is not a complete deep dive into the whole project, but more of a source-code reading note from exploring a real production Go codebase. Feedback is welcome, especially from people familiar with observability systems or large Go codebases. submitted by /u/am0123 [link] [留言]

An AI agent that's flawless in the demo can still fall apart the first time a tool fails in production: a timeout, a network error, a response that comes back corrupted. The fix isn't a smarter model. It's testing the agent against those failures on purpose, before your users do, and hardening it one failure type at a time.

With the Reactive Data Layer Architecture (RDLA), you establish a clear boundary between public data APIs and private, framework-specific data-source implementations. Your presentation layer operates in a purely reactive manner, observing data changes rather than procedurally querying them. RDLA also simplifies testing by encouraging you to program to interfaces and use clean seeding patterns. By Mervyn Anthony
