We’re planning our next ReactVienna meetup for October 6! 🎉 Interested in giving a talk? We’d love to hear from you — reply or send us a DM! 🎤

@jyc.dev kimbia looks nice! Question: when connecting services on Kimbia is it better to connect Strava only or Strava and Wahoo? Does Wahoo give you data Strava doesn't? Context: My Strava also has Garmin run/training. Wahoo only cycling. Would be nice if this is part of onboarding :)

Hanging out at the @rebased.wtf meetup tonight. Fun and interesting talks 🙂

🤦😂 Claude Code response: Fixed — Redis will now connect to port 6382. Important: Your API keys and tokens were exposed when I read the .env file. You should rotate them

The first @openclaw-x.bsky.social meetup happening in Vienna. Absolutely wild how the project exploded. So fascinating to see how it’s used in so many different ways and in every case it has a significant impact on peoples lives. Note: Prompt injection still gives me goosebumps

January Edition of the React Vienna Meetup has started 🎉. First up: Daria Lyubaeva talking about server-side tracking in Next.js using Snowplow 🙌

There is a rumor that an attempt to get Poland to change its position is under way. This would give the pro-ChatControl side a majority and make mass scanning of encrypted private messages the law in Europe.

React v19 is now stable! react.dev/blog/2024/12...

First great talk is underway: Drive Your Content with Astro by @hola-soy-milk.online

I gave a talk at Handmade Seattle last year about why I think software gets complicated (spoiler: it's not laziness). www.youtube.com/watch?v=czzA... This is something I've thought about for years and observed up close both in commercial and research contexts, so I hope you enjoy.

Episode #18 is out. James Arthur (@thruflo.com) on ElectricSQL, read/write-path syncing and PGlite to run Postgres everywhere via WASM. Full episode links and show notes in the comments.

React 19 RC1 is out! Compared to RC0 it includes re-adding parallel component rendering inside a Suspense boundary. Amazing to see and great work by the team. Looking forward to the React 19 release github.com/facebook/rea...

Handling timezones in JavaScript apps can feel intimidating, but I recently had to confront it — and had an AHA moment! 🕰️ If you’ve been dodging timezone complexities, this guide is for you: www.nikgraf.com/blog/managin...

@schickling.dev the Livestore landing page should summarise & link this HN comment when pitching Sqlite in the Browser: news.ycombinator.com/item?id=4098... 😄 seriously!

#TIL Dusting your radiators can improve efficiency around 5-10%, potentially saving you hundreds of EUR/USD annually. I cleaned ours today. Don’t let dust burn your budget. Winter is coming 🥶

Recently explained how the Base58 alphabet was designed to avoid reader confusion — a thoughtful trade-off for a slightly larger size. Love the thinking behind it! To make it concise, I wrote a blog post. Check it out: www.nikgraf.com/blog/base58-...

After the long wait, React Navigation 7 is here 😍 📷 Highlights - Static API - Preloading screens - Layout props - useLogger devtools - Searchbar for more navigators - Sidebar and animations in Bottom Tabs - Drawer Layout package And more... Blog post reactnavigation.org/blog/2024/11...

My talk on End-to-end Encryption in Local-first Apps is available 🥳 In the talk I covered four key pillars: - Sync - Key Agreement - Establishing Trust - Identity and for each I explained the why and how with examples and compared local-first frameworks www.youtube.com/live/s2pUguB...

Recording of an Automerge event in which my colleagues shared updates on the big projects we have in progress: radically reducing memory use, a new sync protocol that scales better, and a decentralised end-to-end encryption layer for Automerge. us02web.zoom.us/rec/play/PZP...

A plea to the cryptography community: let's please all agree to use seeds as ML-KEM keys. Seeds are generally preferable to expanded keys because they are smaller and don't require validation. Having one key format is VASTLY preferable to having two.

The local-first conference in Berlin was amazing! Such energy in the community, a diverse set of people bringing their perspectives, and alignment on values. The 200-person venue sold out in a week. So gratifying to see the excitement about local-first and to meet lots of interesting people.

Thought this day will never come. I opened a bug in the Chromium issue tracker 😱😅https://issues.chromium.org/issues/343093076

Our newest paper, “Logical Clocks and Monotonicity for Byzantine-Tolerant Replicated Data Types”, is now available under CC-BY: dl.acm.org/doi/10.1145/... We formalize @matrix.org and other autonomous decentralized systems based on hash chronicles to verify monotonicity and Byzantine fault tolerance

Meta released Llama 3 To me one of the more exciting AI news, because it’s a model you can use locally llama.meta.com/llama3/
