Hey Twitter Fam!
I built a minimal, toy programming language, Mod (or ModLang) using C++ and STL. It is dynamically typed and interpreted and its syntax is a blend of that of C++, Python and JavaScript.

Now that code is being shipped faster than ever with Claude Opus, we would need Claude Thanos in a few years to remove 50% of code to clean up all the mess.

@bOnstine Is VSCode still used? 🫣

[Pranav Shridhar @pranavmodx]

Claude ke claude lag gaye. 🤡

[Gergely Orosz @GergelyOrosz]

This is either brilliant or scary:

Anthropic accidentally leaked the TS source code of Claude Code (which is closed source). Repos sharing the source are taken down with DMCA.

BUT this repo rewrote the code using Python, and so it violates no copyright & cannot be taken down!

🚀 𝗗𝗮𝘁𝗮 𝗖𝗼𝗻𝘀𝗶𝘀𝘁𝗲𝗻𝗰𝘆. 𝗦𝗶𝗺𝗽𝗹𝗶𝗳𝗶𝗲𝗱. 🛠️

Distributed systems can suffer from "𝘀𝗶𝗹𝗲𝗻𝘁" 𝗱𝗮𝘁𝗮 𝗹𝗼𝘀𝘀 when the database and the message broker aren't perfectly in sync.

If your business logic updates the DB but the event fails to fire (or vice versa), your system is left in an inconsistent state.

I just wrapped up a project tackling this head-on by implementing a high-performance 𝗧𝗿𝗮𝗻𝘀𝗮𝗰𝘁𝗶𝗼𝗻𝗮𝗹 𝗢𝘂𝘁𝗯𝗼𝘅 𝗘𝘃𝗲𝗻𝘁 𝗥𝗲𝗹𝗮𝘆 using a dual-dispatch mechanism (𝗣𝗼𝗹𝗹𝗶𝗻𝗴 and 𝗖𝗗𝗖), it seamlessly supports both 𝗔𝗽𝗮𝗰𝗵𝗲 𝗞𝗮𝗳𝗸𝗮 and 𝗥𝗲𝗱𝗶𝘀 𝗦𝘁𝗿𝗲𝗮𝗺𝘀! 🚀

By using the 𝗢𝘂𝘁𝗯𝗼𝘅 𝗣𝗮𝘁𝘁𝗲𝗿𝗻, we ensure that events are captured 𝗮𝘁𝗼𝗺𝗶𝗰𝗮𝗹𝗹𝘆 within the same business transaction. Here is how I implemented two different ways to move that data from the outbox to the stream:

1️⃣ 𝗧𝗵𝗲 𝗥𝗲𝗹𝗮𝘆 𝗦𝗲𝗿𝘃𝗶𝗰𝗲 (𝗚𝗼 𝗣𝗼𝗹𝗹𝗶𝗻𝗴):
A custom microservice that polls the outbox table. Simple, highly configurable, and great for legacy support where broker-specific CDC isn't an option.

2️⃣ 𝗧𝗵𝗲 𝗖𝗗𝗖 𝗘𝗻𝗴𝗶𝗻𝗲 (𝗗𝗲𝗯𝗲𝘇𝗶𝘂𝗺):
By pairing with 𝗗𝗲𝗯𝗲𝘇𝗶𝘂𝗺, we eliminate polling-to-publish lag and ensure 𝘇𝗲𝗿𝗼-𝗱𝗮𝘁𝗮-𝗹𝗼𝘀𝘀 event streaming by reading directly from the database's 𝗪𝗿𝗶𝘁𝗲-𝗔𝗵𝗲𝗮𝗱 𝗟𝗼𝗴 (𝗪𝗔𝗟).

⚖️ 𝗧𝗛𝗘 𝗧𝗥𝗔𝗗𝗘-𝗢𝗙𝗙:
• 𝗥𝗲𝗹𝗮𝘆 𝗣𝗼𝗹𝗹𝗶𝗻𝗴: Lower infrastructure overhead, but introduces polling latency.
• 𝗗𝗲𝗯𝗲𝘇𝗶𝘂𝗺 𝗖𝗗𝗖: Near-instantaneous streaming and complex transformations, but requires more infrastructure management.

🔥 𝗧𝗘𝗖𝗛𝗡𝗜𝗖𝗔𝗟 𝗛𝗜𝗚𝗛𝗟𝗜𝗚𝗛𝗧𝗦:
✅ 𝗗𝘂𝗮𝗹-𝗕𝗿𝗼𝗸𝗲𝗿 𝗦𝘂𝗽𝗽𝗼𝗿𝘁: Switch between 𝗞𝗮𝗳𝗸𝗮 (Enterprise scale) and 𝗥𝗲𝗱𝗶𝘀 𝗦𝘁𝗿𝗲𝗮𝗺𝘀 (Low latency) with a single config flag.
✅ 𝗛𝘆𝗯𝗿𝗶𝗱 𝗗𝗶𝘀𝗽𝗮𝘁𝗰𝗵𝗶𝗻𝗴: Choose between a custom 𝗚𝗼 𝗥𝗲𝗹𝗮𝘆 (𝗣𝗼𝗹𝗹𝗶𝗻𝗴) or 𝗗𝗲𝗯𝗲𝘇𝗶𝘂𝗺 (𝗖𝗗𝗖) depending on your consistency needs.
✅ "𝗘𝘅𝗮𝗰𝘁𝗹𝘆-𝗢𝗻𝗰𝗲" 𝗚𝘂𝗮𝗿𝗮𝗻𝘁𝗲𝗲𝘀: I implemented the 𝗜𝗻𝗯𝗼𝘅 𝗣𝗮𝘁𝘁𝗲𝗿𝗻 on the consumer side for absolute deduplication.
✅ 𝗣𝘂𝗿𝗲 𝗖𝗗𝗖 𝗙𝗹𝗼𝘄: Zero-lag streaming directly from 𝗣𝗼𝘀𝘁𝗴𝗿𝗲𝗦𝗤𝗟 𝗪𝗔𝗟 (Write-Ahead Log) to Kafka or Redis.
✅ 𝗣𝗹𝘂𝗴𝗴𝗮𝗯𝗹𝗲 𝗔𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲: Infrastructure-agnostic design—easy to run locally or scale out is a snap.

@budapp Would like to try please.

[Pranav Shridhar @pranavmodx]

Huge thanks to @calcsam and the team at @mastra for shipping me a paper copy of 2 incredible books on Al Agents.

I started on the first one, "Principles of Building Al Agents', and can already feel the rare blend of fundamental principles and practical real-world application in it.

"Using too much Al can cause memory loss." - I don't remember where I read this. 😩
