That's a neat visualisation. n^2 = sum(1..n) - sum(1..n-1) = 2 sum(1..n-1) + n => n^2 - n = 2 sum(1..n-1) => n(n-1) = 2*sum(1..n-1) => sum(1..n-1) = n(n-1)/2 And you can rewrite th…

Pressing "Erase browsing history" in the Android persistent notification bar seems to do this.

U2F keys are linked to the associated domain (e.g. google.com or dropbox.com), so your U2F would not present your google.com key to a U2F prompt on googlehax.com This stops the pro…

Use TOTP as a fallback. You might argue "well why bother with U2F, if you are going to set up TOTP anyway", to which I respond that using U2F is still a net win, because for the ti…

I just tried deactivating, and upon logging in to Messenger (which works) it logged me into Messenger, but not FB. Sweet!

This is the argument raised by security experts in http://dspace.mit.edu/bitstream/handle/1721.1/97690/MIT-CSAI... , which I'm not qualified to disagree with. It seems strong! Even…

Are you law enforcement with a warrant?

https://github.com/technomancy/better-defaults aims to be "a small number of better defaults for Emacs". I use it, though I'm not a heavy emacs user.

Same in other parts of Europe, Australia, and New Zealand

CJDNS is a self-organising IP address allocation and routing layer. A node's public key acts as its IPv6 address, and routing uses a DHT of those nodes. This style of network has t…

Oops. Just realised my comment contains a mistake. casync does not act as a server. Its on-disk representation and client behaviour is designed in such a way that the server need o…

SHA-256 seems to score well on https://www.cryptopp.com/benchmarks.html .
