Yup we won a hackathon just by building a todo list dapp!
Thank you my team @teelevelup @LongPh8 @hoc_tap @lgrd149 for making this possible.

[Nguyễn Khôi @nmvkhoi1]

Thrilled to announce my team won first place at the Sui Move Bootcamp Hackathon HCMC! 🚀 What an intense journey—diving deep into Move's object models, ptbs, and building real-world DApps. I have learn so much from the bootcamp.

"Samrt humans figure out it fast"

[Elon Musk @elonmusk]

SpaceX is actively hiring world-class engineers/physicists for SpaceXAI, even if you have zero prior experience in AI. Smart humans figure it out fast.

@bobby_0x00 @avrldotdev Same bro still stuck ln step 1

[avrl ☘ @avrldotdev]

Step-1: Learn Rust
Step-2: Understand ownership, borrowing & lifetimes
Step-3: Master memory safety, zero-cost abstractions & type system
Step-4: Build a CLI tool using Cargo
Step-5: Write a multithreaded server using async Rust with Tokio
Step-6: Read the Rust standard library source. question everything
Step-7: Build a production-grade backend (REST/gRPC, DB, caching, msging)
Step-8: Make it fast & safe (profiling & benchmarking)
Step-9: Eliminate bottlenecks with safety
Step-10: Ship it

@elonmusk I feel like grok features always behind other competitors!

[Nguyễn Khôi @nmvkhoi1]

@ctatedev Hmm this sound like tauri for me

Algorithms by Jeff Erickson - one of the best algorithm books out there.

The illustrations make complex concepts surprisingly easy to follow. Highly recommend this.

Have they hired 3rd audit firm yet? This is such a basic bug!

[Vadim (AI, ⋈) @zacodil]

Aftermath Finance lost $1.14M to an integer overflow bug. The kind of mistake covered in week one of every intro-to-programming course.

The fee was stored as u256 (always positive) but read elsewhere as signed (positive or negative). Pass a number close to the max, signed reading wraps it to a huge negative. Fee becomes rebate. Protocol pays you to trade.

Aftermath's perp source is private. Here's the exploit reconstructed from the on-chain trace:
1. Call create_integrator_info with u256 fee = 2^256 - 10^17 (looks like a huge positive number, reads as -10^17 signed)
2. Place matching limit and market orders between two of their own accounts
3. Each trade fires PaidIntegratorFees - protocol sends USDC to the integrator (attacker)
4. Atomic, repeatable, ~$79K profit per cycle
Final on-chain proof from the exploit tx:
PaidIntegratorFees event records:
- fees: 115792089237316195423570985008687907853269984665640563689698454007913129639936 (= -3.5×10^17 in signed i256)

- integrator_address: 0x1a65086c... (the attacker)

The protocol logged itself paying a wrapped-negative fee to the exploiter. Function signature on-chain confirms: clearing_house::create_integrator_info(Address, U256) with no bounds check.

The April pattern of missing parameter bounds:
- Singularity: oracle fee tier set to 42 (Uniswap only supports 100/500/3000/10000)
- Aftermath: u256 fee parameter wraps to negative when read as signed
- Scallop: spool created without last_index initialization

Same root cause across all three: setters that don't enforce the value range invariants the rest of the contract assumes. AI agents test boundary values automatically. Wrap a number, free money comes out.

@theo Bro Android isn't as buggy as IOS right now

@GBtradecoins @SuiPlay @PLAYTR0N @SuiNetwork Hopefully, luck will come your way.

[DiamondLe.sui🥼|💧 @GBtradecoins]

I paid $638 (X4) for @SuiPlay. Event attendees got it FREE. I never refunded. I held all 4 units. I defended this project. Now I'm sitting here feeling like the biggest fool in the room.

[Nguyễn Khôi @nmvkhoi1]

fricking cool bro

[Aadi Kulshrestha @MankyDankyBanky]

I trained a 12M parameter LLM on my own ML framework using a Rust backend and CUDA kernels for flash attention, AdamW, and more.

Wrote the full transformer architecture, and BPE tokenizer from scratch.

The framework features:
- Custom CUDA kernels (Flash Attention, fused LayerNorm, fused GELU) for 3x increased throughput
- Automatic WebGPU fallback for non-NVIDIA devices
- TypeScript API with Rust compute backend
- One npm install to get started, prebuilt binaries for every platform

Try out the model for yourself: https://t.co/TB2itlmCVT

Built with @_reesechong. Check out the repos and blog if you want to learn more.

Shoutout to @modal for the compute credits allowing me to train on 2 A100 GPUs without going broke

@0xQuynhMi @MarginATM @imlethanh98 @khaihoan_ne hmmm I wonder what happened

I know you're all getting mighty tired of seeing typography on your timeline today!

But here's a pretext.js demo that (hopefully) isn't a crime against justification and indentation.
