TheZZAZZGlitch's awesome April Fools 2017 event (Game Boy reversing challenge) is now over. Here's my writeup: https://gist.github.com/Wack0/1a84651e7e7e0c6f7d5fb5888e361123

a really sweet article about reverse-engineering and exploiting the Broadcom WiFi firmware https://googleprojectzero.blogspot.com/2017/04/over-air-exploiting-broadcoms-wi-fi_4.html

Still trying to get my head beyond 140 chars, so for now I'll just ctrl+v each message 3 and a half times per toot.

"Thus, determining the correct rate
at which to refresh DRAM cells has become more difficult, as also
indicated by industry [45]. This is due to two major phenomena, both
of which get worse (i.e., become more prominent) with technology
scaling. First, Data Pattern Dependence (DPD): the retention time of a DRAM cell is heavily dependent on the data pattern stored in itself and in the neighboring cells [69]. " - worth reading: https://arxiv.org/pdf/1703.00626.pdf
