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 that as... sum(1..n) = n(n+1)/2

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 proxy attack you describe getting a session key, but not gettin

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 times you use U2F, you are safe from phishing attack

I'm not sure of the relevance of this to jstanley's argument, nor my rebuttal.

Is the home secretary using that argument? We ought to use strong arguments. This thread's arguments aren't strong.

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.

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 the property that you can take two independent CJDNS net

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 only serve static files. This makes deployment easy.

Great. The chunked model (inspired by Borgbackup/Tarsnap) seems preferable to Docker layering, and diff-based approaches. As far as I can tell, the advantages compared to Borgbackup seem to be: * casync offers control over which FS met

Sorry, I didn't explain myself well. Range.closed(1,5) is the syntax used to refer to what a mathematician would call [1,5]. Guava is just a Java library. In Java 9, a two-Integer-element list literal will be List.of(9000, 9001).

Fixed, thanks.

by tomfitz 9y ago
An alternative approach is Guava's Range class: Range.closed(1,5) == [1,5] Range.open(1,5) == (1,5) Range.openClosed(1,5) == (1,5] Range.closedOpen(1,5) == [1,5) Range.greaterThan(1) == (1,infinity) Range.atLeast(1)
