Passion Before Fashion: Stories From a Life of Hacking
The hacker community has changed since Joe Grand first discovered it as a kid in 1982. Back then, tinkering with technology was a guarantee for ridicule and torment. Only those truly curious were connecting to computer systems, traversing the telephone network, and occasionally causing mischief. Today, hackers have largely become accepted into mainstream society and, at times, even influenced by corporate culture. [ continue ]

JTAGulator®
On-chip debug (OCD) interfaces can provide chip-level control of a target device and are a primary vector used by engineers, researchers, and hackers to extract program code or data, modify memory contents, or affect device operation on-the-fly. Depending on the complexity of the target device, manually locating available OCD connections can be a difficult and time consuming task, sometimes requiring physical destruction or modification of the device.
