David Wong’s writing is great, and very accessible.
If this article was of interest, then I can highly recommend James Gleick’s book “The Information”.
+1 that and also “A Mind at Play: How Claude Shannon Invented the Information Age”
… the six collaborators drew on a wide breadth of scholarship. The paper’s citation list, with 128 references, is notably long.
Honest question since I know next to nothing regarding research papers: does the amount of references a paper has matter to people who generally tend to read them? If so, why? Do other papers in the field tend to have less?
It’s notable here, as one of the arguments Google’s given as defense of ordering the paper retracted is that it ignored too much other relevant research. 128 references is about an order of magnitude higher than what I feel is typical, based on the papers I’ve read. To be fair, I haven’t read many papers on the state of research and you’d expect that kind of review to have more references, but this absolutely smashes any expectations I’d have and makes the claim that it ignored research hard to swallow.
In general, the quantity of good references in a paper reflects how well it’s grounded in existing research. How important prior work is to the paper’s claims will depend heavily on the paper in question. And, of course, if the citations are all garbage then it’s a huge red flag, but I haven’t heard anyone claim that here.
I think it depends on the type of paper. If it’s a paper presenting brand new research, you’d expect to have a few references (my personal, very rough metric is “about as many as there are pages in the paper,” although they don’t have to be evenly distributed in terms of citations, and isn’t a hard and fast rule!); if it’s a survey paper or something that is collecting lots of other research and commenting on it in some systematic manner then I would expect more.
128 seems a lot by most measurements, but if it only had 30 references (and interesting subject matter) I probably wouldn’t throw it out. I don’t think it’s overly important.
I would imagine it matters in peer review. I have heard of cases of papers being rejected because they don’t cite some paper the reviewer wrote. Citing a lot of papers could also be some sort of defence against that. Not saying that’s what this paper is doing though.
What kind of model answer do you think he’s expecting here?
Something like “A->B is equivalent to !A v B, so in the case of !A it doesn’t matter what B is, and in the case of !B we’d better have !A”? Or is he expecting someone to mention Modus Ponens and Modus Tollens? I agree this is likely bread and butter for anyone with a theoretical CS / logic background, but I think if you haven’t ever come across/been taught the definition of ‘implies’ it’s really counter-intuitive at first.
Oh, guess I misread it as “what can we say about !A, and what can we say about !B”, rather than “what can we say about (!A and !B)” :-)
Yes, I think so. Honestly though, with logic rules like this, if I’ve not seen a particular variant before I’m never 100% sure that I’ve got them right if I try and work them out in my head. I usually end up writing down a small truth table to make sure I’ve got the outcomes correct.
Glad you enjoyed it!
I’m working on a follow up because I got a bunch of replies fixing errors in the post, describing solutions that work for them in much less time, three or four improved solutions to the exact same problem. Part 2 will have even more useful info!
I wanted IKEv2 for performance and security reasons (I won’t elaborate on this here, if you’re curious about the differences, there’s a lot of content out on the web explaining this).
A similar setup and blog post for WireGuard would be even better still, in terms of both performance and security! @zx2c4
Well to be fair, this isn’t overturning any physics, but rather an attempt at proving something we already believe is true (at least in practice; all our cryptography depends on it).
Amused (one year on) that this is the only story I’ve submitted which has been actively downvoted.
