In this video, recorded live at linux.conf.au2016 in Geelong, Angus Gratton explains his (and others) efforts in reverse engineering the ESP8266 module using Free and Open Source tools. His talk covers a brief history of the device, how it came to be and his own anecdotal views on where its all going. Share on Twitter ∙ Share on Facebook
Now that the author has reverse-engineered the overall instruction decoding and sequencing mechanism we now have enough context to make a start on reverse-engineering the circuitry that generates the ALU’s control signals. This turns out to be more complex than he first expected and a full understanding of what’s happening will probably have to wait until other parts of the processor have also been reverse-engineered.Share on Twitter ∙ Share on Facebook

Recently a Google engineer noticed that their SSH client segfaulted every time they tried to connect to a specific host. That engineer filed a ticket to investigate the behavior and after an intense investigation they discovered the issue lay in glibc and not in SSH as they were expecting.Share on Twitter ∙ Share on Facebook
