No disagreement there - see our work on standardizing tcpcrypt in the IETF tcpinc working group for our attempts to improve one small corner of this space. https://datatracker.ietf.org/wg/tcpinc/charter/

I've been working on VoIP and Internet multimedia since 1991 (I'm one of the authors of SIP, for my sins) so, yes, we've been concerned about time-sensitive material for a long time. From a standards point of view, this resu

Interesting to see this paper making HN. I think it has stood the test of time reasonably well - it was written in about four hours one morning under rather unfortunate circumstances - I was stuck on a train that hit a vehicle at a crossin

So if you want to get your competitor banned from the App store, just post lots of spammy positive reviews for their product? How would you defend your app against such an attack?

On the other hand, I've repaired my Bosch washing machine twice in the last year. Once to replace the pump (somehow it ate a pair of tweezers - still not sure how!), and once when one of the mounting brackets for the main drum suspens

Yes, you're correct - I shouldn't have said "cycle". I was refering to an Eulerian path, which is all you need to solve the Bridges of Konigsberg problem as it is described in the article. A cycle adds the constraint t

Given that Apple control their own CPU designs, how hard would it be for them to add a hardware x86 ISA emulation layer over their ARM CPU for use with MacOS? That way the OS and newer software could be compiled for ARM, and legacy softwar

If you knew for sure that an IP src address involved in a DDoS attack was not spoofed, we could easily design a control protocol that allowed a recipient to contact the origin ISP and enable a block on that particular {src,dst} pair. Unles

It's really useful to have one lying around though. When I upgraded my home Mac to El Capitan, it stopped being able to talk to my old HP laserprinter. After I'd stopped cursing, I grabbed a Pi that was lying around waiting for
