Llama 4 is here!

Ha! A conditional return type in TypeScript

It took almost 100 hours of Claude 3.7 Sonnet usage (via Sourcegraph Cody) for me to finally see it hallucinate. I almost forget that's a thing.

proposal: crypto/ecdsa: add NewPublicKey and PublicKey.Bytes · Issue #63963 · golang/go I'm working with the JS Web Push API to send push messages, which uses an ECDH Key in base64-encoded X9.62 uncompressed form, like BJ932huv68tUDxifpf6qlzuRa_JBF-2E9J47alSQRuxpmt3QFtiCnhqXlPgZuGWKZz...

I just realized we can finally deprecate the ecdsa.PublicKey X and Y big.Int fields once NewPublicKey and PublicKey.Bytes land!

If you use them for ECDSA or ECDH and can't migrate to NewPublicKey/Bytes or crypto/ecdh, now is the time to let us know.

(If you use them for exotic things, use nistec.)

Gemini 2.0 Flash is comically bad compared to Claude. Don't believe the type, 3.5 Sonnet is still the best at coding.

For context, I'm doing a refactor here and spent a bit of time editing 2 of about 30 files to get them right. Then I realised the other 28 would be pretty repetitive, so I just dumped the last two git commits into the diff files e.g. `git diff HEAD~2 HEAD~1 > diff-2.txt`

Sourcegraph Cody chat prompt with: "use diff-1.txt diff-2.txt to refactor s3.ts resources.ts in a similar fashion. provide diffs."

The most powerful prompt I've found for refactoring. So simple. Using the new Claude 3.5 Sonnet the diffs are awesome, you can follow-up in the chat to refine them if need be, then use @sourcegraph.com Cody Smart Apply to have it apply the actual edits live. Easy. Fast. Accurate.

The hardest choice you have to make when building in TypeScript is Bun @bun.sh or Deno @deno.land and honestly feels like you can't lose at this point

Bun 1.2 Built-in Postgres client with Bun.sql, built-in S3 object support with Bun.s3, a new text-based lockfile: bun.lock, Express is 3x faster, and a major update on Node.js compatibility.

Introducing Bun 1.2

10 years from now TypeScript, React, Tailwind CSS, PostgreSQL, & Kubernetes expertise will absolutely still be in high demand and used by successful tech companies. Why? They've already been around for at least as long (except Tailwind at '17) and keep growing/improving.

pg_mooncake put Postgres in the Clickbench top 10 by transparently embedding DuckDB for columnstore queries

Yeh I think the way I did it I only needed it in dev and not argocd. Hope it works out for you!

I used envsubst. I think someone made a helm plugin for it too.

🦁 brave web browser.
📋 linear for project management/issue tracking.
🍓 jam for one click bug reports devs can actually repro.
👀 runreveal to get alerts on important security logs.
📝 obsidian for md notes synced with icloud or gdrive or git.

what's your fav tech right now?

8/8.

📊 duckdb or clickhouse for storing huge data for olap queries. love being able to store the data in s3 with these.
⛁ duckdb or trino for querying bi data across data stores (trino can parallelise queries).

7/n

💡 sqlite for small db's (e.g. sqlite in durable objects when using cloudflare workers)
🤝 postgresql on neon or aws aurora for transactional/most db's. aurora serverless v2 is great but can't do reserved instances so not always. prefer neon most of the time.

6/n

🤖 podman for running (docker) containers & k8s locally. rancher desktop next best alternative.

5/n

☸ k9s cli ui for working with kubernetes (k8s).
🚢helm for managing k8s apps/manifests.
🔄 argocd for gitops continuous deployments on k8s.
🌐 traefik for reverse proxy into k8s services.
🤫 sealed-secrets for gitops encrypted secrets on k8s. kubesealplus for a better dx managing secrets.

4/n

📄 cloudflare pages for hosting typescript apps.

🤖 go (golang) for perf-sensitive backends and cli tools.

🔐 aws-vault for securely storing aws creds.
📜 mkcert for generating trusted certs in dev.
🔏 cert-manager for certs in production.

3/n

🍞 bun for typescript deps and runtime.
⚡ vite and vitest for builds and testing.
💿 remix / react router 7 for apps with a UI.
⚛️ tailwindcss for styling UI.
🔥 hono for typescript backends.
🛡️ zod for schema validation.
⌨️ conform for form validation using zod.

Fav tech January 2025:

🛠️ pixi to install code tools/runtimes/etc.
📁 chezmoi to sync .dotfiles across machines via git.
🖥 ghostty terminal with tmux.
#️⃣ zsh shell with oh-my-zsh.
📝 zed code editor.
🧠 claude 3.5 sonnet for ai code assistance.
🤔 gpt 4o for other ai assistance.

When I was a teenager, I opted to self-learn Linux, PHP, and MySQL because I simply could not afford anything in the MS ecosystem, despite .NET being touted in magazines as the 'next big thing'. My Linux & PHP experience definitely helped me get the gig at Cloudflare. Thank you Open Source ❤️

Any websites were able to send any requests to the development server and read the response ### Summary Vite allowed any websites to send any requests to the development server and read the response due to default CORS settings and lack of validation on the Origin header for WebSocket co...

Vite 6.0.9 / 5.4.12 / 4.5.6 has been released with *breaking changes* due to security issues. I recommend upgrading it. Some users may need to update the config options. Please check github.com/vitejs/vite/... if you encountered any errors.

Conform, a client + server form validation library, which can use Zod/Yup/etc for validation schemas - definitely best option out there IMO for building forms in Remix/React Router 7. Nice work @edmundhung.bsky.social !

JSONC is one of the best configuration formats out there. I wish more tools supported it. Maybe someone needs to make it an official standard / write an RFC for it? Given the level of awareness and usage you would think Microsoft's node-jsonc-parser GitHub repo would have more ⭐

Screenshot of the Type Inference decision doc showing credit to the Svelte Kit team for learning about the TypeScript 'rootDirs trick'.

The Remix / React Router decision doc for Type Inference (#0012) is a fantastic example of the utility of decision docs. My favourite part is that they not only explored how others did things, but actively acknowledged when they were able to leverage the learnings. github.com/remix-run/re...

Screenshot of the Remix/React Router roadmap showing the Middleware Github issue #12695.

Here's what I'm most excited about in the Remix/React Router roadmap: Middleware, coming soon!

I am convinced 99% of websites should use magic links + passkeys.

It bypasses all (debatable) portability objections to passkeys, it’s at least as secure as email-based recovery, as fast as a password manager, it’s available to all users… and importantly, no passwords!

Fantastic!
