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.

Rescue Your Crashed Linux System: The Chroot Technique

Is your Linux system refusing to boot? Don't panic! This post introduces the chroot technique, a true Swiss Army knife for Linux systems. By mounting the hard drive of your broken system into a working one (e.g., a live USB), you cleverly create a new root directory containing the broken system's files and essential system folders. After using the `chroot` command to switch to this new root, you can fix your broken system as if it were running normally, executing commands like `apt update` and `dpkg-reconfigure`. This technique once saved the author's Nanopore GridION device!

Man Page Links: It's Not the Man Pages, It's the Readers

2025-04-09

Common complaints about man pages include the lack of inter-page links and reflow on window resize. However, the mdoc(7) format used by man pages actually supports these features, using macros like `.Xr` and `.Sx` for creating links. The problem lies with man page readers (like `man(1)` combined with `less(1)`), which fail to implement this functionality. We need better man page readers that natively support links and reflow, rather than simply formatting the man page and piping it to `less(1)`.
