Hacker News debated "Open Social," focusing on the AT Protocol vs. ActivityPub. Discussion covered AT Protocol's tech, its potential advantages, and the challenges of widespread adoption for decentralized social media. #OpenSocial 1/6

The viability of decentralized social media is questioned. Concerns arise about the inherent need for centralized aggregation points and the potential for a single entity to dominate even open protocols. #Decentralization 5/6

Hey Bluesky, I know how people here just LOVE everything AI, so I wanted to show you what @threepointone.bsky.social and I have been up to. We made an agent that calls MCP not as "tools", but by converting the tools into a TypeScript API, and writing code against that. blog.cloudflare.com/code-mode/

✍️ How modern browsers work addyo.substack.com/p/how-modern... - my write-up on browser internals for web developers

I gave a talk on modern React patterns, including concurrent features, Actions, and the new <ViewTransition> component, at @reactuniverseconf.com last week. Watch the talk here! www.youtube.com/watch?v=I3As...

Great! Bluesky now supports bookmarks. Yay🎉

Really liked how you set up a Signal link in your Bluesky profile so people can start a DM conversation with you directly. I borrowed the idea and added a similar link from the 'about' page on my own site.

🔥 Today we're shipping something special at @platformatic: Next-generation flamegraph visualization for Node.js! We've built a complete profiling ecosystem that makes performance optimization intuitive and actionable. Let me show you what we've cooked up 🧵

🛠️ New Article: The Basics of Anchor Positioning I wrote an article covering some basics of CSS anchor positioning. Really excited to share this one! 🤩 🔗 ishadeed.com/article/anch...

B-trees vs LSM trees. Heap files vs clustered indexes. So much to talk about! Designing Data-Intensive Apps stream # 2 tomorrow, 9AM PST. Join in the fun on Youtube: www.youtube.com/watch?v=LHWg...

We’ve added a Queue Dashboard UI. Easily manage your queued jobs with built-in concurrency control, without needing Redis or any external database. Try it out in the v1.22.0! Huge thanks to @ghansham for the countless feedback and support!

If you are using the Vercel AI SDK and in the Vercel ecosystem, this sounds very interesting. They allow you to bring your own keys. And, no added markup or middleman fees on model prices; you pay the model provider directly. That is pretty good 👏

I needed a simple S3 utility and didn't want to install aws-sdk, so I wrote one (~89 KB): https://www.npmjs.com/pa...

A visualization on (how I think) neural network works, made with threejs and animejs 🔗 visualrambling.space/neural-network I have so much fun learning and making this, so I think I want to keep going.

My hacker news bot has a new handle: @hot.hn

Introducing Bases, a new core plugin that lets you turn any set of notes into a powerful database. Now available to everyone with Obsidian 1.9!

Just published a walk-through into creating your own did-method-web identity for ATProtocol! 🔧 Most folks use did-method-plc (the default), but there's another way that gives you more control in exchange for additional complexity and risk. 🧵👇

Today, we're announcing our first hosted infrastructure product: pyx, a Python-native package registry. We think of pyx as an optimized backend for uv: it’s a package registry, but it also solves problems that go beyond the scope of a traditional "package registry".

The day comes for every parent when they have to have The Talk

🚨 New Course Alert 🚨 DevTools for Beginners @kevinpowell.co and I just released a brand new (and totally free!) email course all about DevTools and how to use them in ways that actually help you debug and improve your CSS. 🔗 Full details and free signup here: devtoolsforbeginners.kevinpowell.co

The 9650 PCIe Gen 6 SSD achieves up to 28GB/s sequential read and 14GB/s sequential write. And 4080’s memory bandwidth (716.8GB/s). close to 25x slower. I understand this is really fast storage speeds, but can someone explain how this SSD can help with "AI training and inference acceleration"?

Figma is going public today (31 July). Here's their tech stack, at a high-level, from the deepdive with CTO Kris Rasmussen in The Pragmatic Engineer back in 2023: The full deepdive on how Figma operates from an engineering point of view: newsletter.pragmaticengineer.com/p/inside-fig...

@dagu-org.bsky.social - I see a new version of Dagu released on Github - v1.18.0 🎉 But I am having trouble installing this version with brew. More details here: github.com/dagu-org/dag...

Tailwind just released a set of interoperable web components! If you use a framework other than React, or no framework at all, this is huge. tailwindcss.com/blog/vanilla...

Real-time, decentralized social apps — without running a single server. Here’s how to build and deploy an atproto app on Cloudflare Workers. blog.cloudflare.com/serverless-a...

New data oriented file format just dropped. FastLanes, "like Parquet, but with 40% better compression and 40× faster decoding". 👀 Seems it can exploit correlations between columns and have fully SIMD friendly encodings to help with vectorization. github.com/cwida/FastLa...

How well do you know Python’s f-strings? I built a thing inspired by JavaScript’s Date constructor quiz but for Python. fstrings.wtf

Thanks for letting me know of the issue. I updated the website to remove those characters, so it should be working now.

TIL: When you copy a Bluesky handle from someone's profile page, it includes invisible Unicode characters (U+202A & U+202C). This is because, the web app wraps handles in HTML like: &#x202A;@username&#x202C; This is a problem if you try to use the copied handle directly, for e.g. in an API call.

I gave a talk earlier this year at the internal Microsoft Performance Symposium called "Five True Things", and the goal was to convey some really basic properties about computers today. A short thread to recap them:

Neat tool for checking when an account joined Bluesky: bluecrawler.com/tools/bluesk... I wanted to know when I joined.

You can DIY upgrade the M4 Pro Mac mini's internal SSD to 4TB—for almost half Apple's upgrade pricing (but still 3x what normal M.2 NVMe SSDs cost 🙄) How does that compare to external Thunderbolt 5 storage? A video: www.youtube.com/watch?v=cqmP...

Saw this brilliant corrupted Node.js warning by @jakebailey.dev and wondered how it's made - so, I looked it up. Post link: bsky.app/profile/jake... It's called "zalgo text" and uses Unicode combining characters! Here's how it works... 🧵👇

Bredbox, my Pocket clone - two things to know: 1. Completely written by AI. Great test for upping my Copilot skills. 2. Starting with what Pocket provided, but I have lots of ideas to improve it. Sign up for test run notifications: https://bredbox.app

ATmosphere Report - this week's bluesky and atproto news: - More notification settings for Bluesky - How atproto is becoming a place to build multiperson LLM chatbots - Bluesky's proposal for Auth Scopes also introduces new questions for governance connectedplaces.online/reports/atmo...

Ooh, my Chrome DevTools extension for debugging Scroll-Driven Animations is approaching 3000 users … - Live Minimap (!) - ScrollTimeline and ViewTimeline support - CSS and WAAPI SDAs supported - Plays nice with `position: sticky` - Visualize and edit the animation-ranges 👉 brm.us/sda-debugger

RustDesk is a wonderfully useful remote desktop and support tool. It's even better paired with Tailscale, which handles the details that normally require self-hosting.

I'm totally biased, but is there anything better than a crispy Masala Dosa, or plain Dosa with coconut chutney? 😋 Found this easy-to-follow recipe that actually works: www.andy-cooks.com/blogs/recipe... Video version for visual learners: youtu.be/_x0SYjQAH2A

Loved the energy at this meetup. There were demos from @skylight.social, @sprk.so, @germnetwork.com and others. The initial talk @knowtheory.net introduced us to the variety of apps that are being launched on the AT Protocol. And finally, we also got a tour of the Internet @archive.org.

Hey out there to our Bay Area ATProto nerds and ATProto curious friends. @germnetwork.com and ATProto Community Fund are hosting an ATProto meetup at the Internet @archive.org this coming Tuesday July 8th! Come on out, hack and chat: lu.ma/mf4n7jbi

Starting CrossFit again after a long hiatus. Found a great box close to home and doing the smart thing - beginning with personal training sessions to get my form dialed in. Injury prevention > ego. Here we go 💪

Really enjoyed this talk by @mitsuhiko.at about Agentic Coding using Clause Code. With @sli.dev, you can create presentations with MD files and it seems this presentation itself was created with the help of Clause Code.

It's time for another electric vehicle charging video. Too many people believe EV charging solutions require expensive, huge electric circuits (or worse: service upgrades). The really high-power ones people tend to go with can be a headache, but there are many other options! youtu.be/W96a8svXo14
