This commentary advances the ‘hack’ as an urban concept. While hack transcends existing literatures on digital and informality, it is a distinctive concept being used systematically in new domains. I situate conceptually, outline its empirical methodological value propose framework to research hack. Importantly, not just technologies of hacking but translation computational logics that underpin...

TCP has been designed and tuned as a reliable transfer protocol for wired links. However, it incurs end-to-end performance degradation in wireless environments where packet loss is very high. TCP HACK (Header Checksum Option) is a novel mechanism proposed to improve original TCP in lossy links. It presents an extension to TCP that enables TCP to distinguish packet corruption from congestion in ...
