      Sorry to be offtopic but does anyone know a method to log back into an instagram account??
      I stupidly forgot my password. I appreciate any tricks you can offer me!

      @Zayden Luciano I really appreciate your reply. I got to the site thru google and Im waiting for the hacking stuff now.
      Seems to take a while so I will get back to you later with my results.

    "A fault in many DRAM modules, from 2010 onwards"
    No, actually, it's a fault in DRAM since.... DRAM. Part of that whole "D" letter.
    Edit:
    I'm realizing now that the 2010 date is about the vulnerability awareness, not the physics. The physical situation that allows for rowhammer scenarios has been around since DRAM has existed. That's part of why ECC exists and refresh limits are specified. The density of contemporary DRAM, however, does make the issue more prevalent, so something that needs to be addressed.

      Not quite. It's not observed on DRAM < 2010 because the memory cells are sufficiently large and far apart and memory controllers sufficiently slow that you can't do enough reads in a refresh interval to cause the issue. This is something that happens on newer DRAM because they are more dense. Prof. Mutlu mentions this in th-cam.com/video/sgd7PHQQ1AI/w-d-xo.html at 10:28

    will the xbox one be vulnerable to row hammer and would a magnet near ram memory have and effect?
