Analysis of PS4's security and the state of hacking
FreeBSD jails and Return-Oriented Programming:
Think of [Return-Oriented Programming] as writing a new chapter to a book, using only words that have appeared at the end of sentences in the previous chapters.

FreeBSD breaks its kernel RNG for 4 months
If you are running a current kernel r273872 or later, please upgrade
your kernel to r278907 or later immediately and regenerate keys.
I discovered an issue where the new framework code was not calling
randomdev_init_reader, which means that read_random(9) was not returning
good random data. This means most/all keys generated may be predictable and must be

a file system that stores all its data online using storage services like Google Storage, Amazon S3, or OpenStack. S3QL effectively provides a hard disk of dynamic, infinite capacity that can be accessed from any computer with internet access running Linux, FreeBSD or OS-X.

S3QL is a standard conforming, full featured UNIX file system that is conceptually indistinguishable from any local file system. Furthermore, S3QL has additional features like compression, encryption, data de-duplication, immutable trees and snapshotting which make it especially suitable for online backup and archival.

packetdrill - network stack testing tool
[Google's] packetdrill scripting tool enables quick, precise tests for entire TCP/UDP/IPv4/IPv6 network stacks, from the system call layer down to the NIC hardware. packetdrill currently works on Linux, FreeBSD, OpenBSD, and NetBSD. It can test network stack behavior over physical NICs on a LAN, or on a single machine using a tun virtual network device.
