@nifferkin @foundersysk @bohannon_bot What a delightfully refreshing, weird, and memorable intermission activity 🤣 @bohannon_bot kudos to you for somehow convincing a room full of engineers and founders to do this!!

(1/30) @ethereum basics: Fee Systems, Before and After EIP-1559

Ethereum is limited by the hardware & bandwidth of its nodes; fee systems work to fairly distribute these resources to any interested in using the World Computer

The original, and the what, why and wow of EIP-1559

A new scam called 'Address Poisoning' is on the rise. Here's how it works: after you send a normal transaction, the scammer sends a $0 token txn, 'poisoning' the txn history. (1/3)

Think you understand how DELEGATECALL works in Solidity (and the EVM)?

How could you exploit this contract and take ownership?

Flipper Zero: The Thread. I received a Flipper Zero a few days ago, and since I'm idling here at my parent's house, for the holidays, I spent a lot of time playing with it. This thread captures my impressions about the device.

mmap() is a tremendously important Linux syscall. Many open-source and in-house databases and KV storages use it internally to simplify data access. That's why it's so essential for SREs to understand its interaction with Page Cache: https://t.co/SaLhniuPpK

✨✨Understanding SSTORE2 ✨✨
In this article, I go about talking about Solady's implementation of SSTORE2, looking at each line of YUL
SSTORE2 allows storing information gas-cost effectively utilizing contract's bytecode as storage

Ethereum is like a blackhole.

Art, banking, politics, payments, gaming, communities, entrepreneurs, creators, devs & even real world assets.

The bear market likes to hide this fact, but it’s important to take a look behind the curtains…

There is 0.1 ETH on the contract.
You have time until 2023. Who will get it first?

🚨 Watch how I can run up a $1000 bill with a single call to a poorly protected LLM app 🚨

Prompt injection attack against an agent: tricking it into repeatedly calling the LLM and SerpAPI, quickly racking up costs

[cygaar @0xCygaar]

Today, I decided to do a deep-dive into the age-old gas saving trick:

Using ++i instead of i++.

You may have seen this trick and asked yourself how a change this trivial and inconsequential could result in a difference in gas usage.

Well folks, here's the full explanation 🧵:

Recommend @binarybits' account of driving for Lyft, earning $1,111 over 46 hours (~52% of 100 fares).

Conclusion: "The more I’ve looked into it, the more I became convinced that it’s going to take major cost-cutting for Lyft to avoid eventual bankruptcy."

Wrote a quick lil script to disassemble EVM bytecode and parse out function selectors.

Useful if you want to see what function selectors an unverified contract implements, call `selectors` and then query `https://t.co/MDiNkmC2fb` with a batch query.

The Most Innovative award went to FedTorch, built by @muxfdz & Minke Zhang. FedTorch allows anyone with a GPU to join a global cluster on a P2P network and pay to use GPU's on a per-job basis through distributed auctions.

The GRAND PRIZE winner was AI in Spreadsheets, by @hansonwng and Ethan Carlson. Imagine being able to clean data like a human would, unbound by the rigid logic of spreadsheets. Now watch it actually happen. It's impressive.
