  • Spectre, explained as if computer were banks /img/spectre-and-meltdown.jpg

    I just saw on Twitter a thread by Professor Clay Shirky that gives a good, simple explanation of what Spectre is and why it is dangerous (which I believe to be valid, in a broad sense, also for the other big computer threat of the moment, Meltdown (1)). With Prof. Shirky’s permission, I reformatted the whole thread and now publish it here, so that it is fully readable, and useful, even outside Twitter (emphasis in the text below is mine)

  • Once more: online or e-voting? No. Just no /img/what-part-of-no-e-voting-dont-you-understand.jpg

    Whenever the results of a vote would not have substantial impacts on the people who did not, or could not vote, eligible voters are welcome to use whatever suits their fancy: e-voting, tossing dices, goat entrails… We won’t notice, so no problem. In all cases of really important voting instead, that is (at least) all political or administrative elections: here is why online/e-voting is something that you should just avoid, period.

    E-voting is coming, or has already arrived, in my Country. How can I understand if it’s implemented properly, without risks of abuse? What is the right way to e-vote?

    Let’s start with the real question that almost nobody asks: is e-voting necessary in the first place? Does it really makes any sense at all?
