Vortrag angemeldet: What we are really looking at? Mediennostalgie und Retrogaming
Mediennostalgie und Retrogaming sind in aller Munde. Aber was sind eigentlich die Grundlagen dieser Bewegung? Welche psychologischen Phänomene spielen hierzu eine Rolle? Und warum ist gerade das Computerspiel quasi prädestiniert dafür, als nostalgischer Anreger zu dienen? Der Vortrag von Sebastian Felzmann bündelt diese Fragen und gibt einen Überblick über die aktuellen Wirkungstheorien der Nostalgie in Verbindung mit der Entwicklungslinie des Mediums Computerspiel. Dabei kann das Spiel natürlich niemals ohne die materielle Grundlage, also die Computer- und Videosysteme, gedacht werden.

Low Cost SimpliSafe Attacks
Earlier this week, Dr. Andrew Zonenberg of IOActive published a security advisory and blog post describing weaknesses in the SimpliSafe home security system. He showed that components of the system, such as the keypad, transmit unencrypted radio signals that can be captured and replayed. He also pointed out the significant problem that SimpliSafe devices are physically incapable of being reprogrammed with improved firmware that might address such vulnerabilities.
I know Andrew and have great respect for his reverse engineering and hardware hacking talents. He implemented a replay attack by making small modifications to SimpliSafe devices, monitoring and controlling them from his own hardware platform. To demonstrate...
Диагностика Imprecise Bus Faults в микроконтроллерах Cortex-M3/M4/M4F
При разработке программ для систем на микроконтроллерах серий Cortex-M3/M4/M4F программисты, бывает, сталкиваются с исключениями ядра, когда программа останавливается в бесконечном цикле в обработчике FaultISR. Как правило, попадая в этот обработчик вы уже не можете определить что произошло, т.к. стек вызовов в отладчике уже не отображается. Еще хуже, если в регистре Fault Status появится ошибка Imprecise Bus Error. Вот про диагностику этой ошибки я и расскажу.
