Advent of Code: Elegant Solution to a Stateful Parsing Problem

2025-04-09

The latest Advent of Code puzzle involves interpreting `do()` and `don't()` instructions that enable or disable the contribution of `mul` instructions to a sum. Regular expressions struggle with this statefulness, as they recognize stateless regular languages. The author uses a parser-based solution, lifting it into a state transformer to create a stateful parser. This parser efficiently handles `do()`, `don't()`, and `mul` instructions, processing roughly 1MB of input in 0.12 seconds—a significant improvement over a regex-based approach.

OpenSSL 3.5.0 Released: Ditching the Three-Way Handshake for 0-RTT

OpenSSL 3.5.0 has been released, featuring support for various post-quantum cryptography methods and 0-RTT connections. The traditional three-way TCP handshake is considered too slow in today's always-on world. 0-RTT (Zero Round Trip Time), integrated into TLS 1.3, lets clients reconnect instantly without the handshake. A full handshake occurs on the initial connection, generating a session ticket used for subsequent connections, allowing the client to send data immediately without waiting for a server response. While security risks like replay attacks exist, 0-RTT's compatibility with the UDP-based QUIC protocol positions it as a key trend in future network connections.

SPVs and the Shadowy World of Pre-IPO Trading

Private company share trading is booming, with accredited investors increasingly accessing pre-IPO shares through platforms like EquityZen and Forge Global. However, these trades often involve Special Purpose Vehicles (SPVs), which own shares of the operating company, bypassing securities laws designed to limit the number of investors. This allows companies to stay private longer and raise capital, but it also exposes investors to opaque funding vehicles with hefty fees and limited transparency. The underwhelming IPO of CoreWeave highlights the risks, suggesting that reliance on private markets isn't sustainable without a robust public market for accurate valuation. The system exposes moderately wealthy retail investors to significant dangers.

Trump Admin Dismantles Crypto Fraud Unit, Embraces Deregulation

The Trump administration has disbanded a Department of Justice unit focused on cryptocurrency fraud, ending what it terms “regulation by prosecution.” A memo from Deputy Attorney General Todd Blanche instructs prosecutors to halt actions imposing regulatory frameworks on digital assets, ceasing investigations into exchanges, mixers, and wallets for user actions. This shift aligns with Trump's recent pro-crypto stance, fueled by donations from crypto billionaires and his own crypto initiatives. Instead, the DOJ will prioritize prosecuting individuals using crypto for criminal activities like terrorism and drug trafficking. This deregulation raises concerns about potential risks and regulatory gaps.
