"All Questions Answered" by Donald Knuth

[okosenkov]

So, a guy at 29:25 mentioning about "Not scale very well". What an arrogant person. Who did he make fun of, himself? I'd like to see him scale well in 30 years from now.

[dashwinterson]

@okosenkov true, but I think knuth got the joke

[guygallagher410]

This vid went viral on Libya

[frederikcreemers]

I like his writing better than his speaking, because of the stuttering, it gets hard to concentrate on the content, but I still have very deep respect for a man so smart, and still so friendly.

the OLD Guy stderring or is it b/c hes OLD

Don is so humorous

[DCWhatthe]

One of the great things about Don, is that his love for his subject hasn't diminished with age. He recorded a video called 'Fun with Binary Decision Diagrams', and you can just feel all the intense passion & connection he has with his topics.

[georgepowell]

He doesn't talk as well as he writes. That's a shame.

[purple9414]

did he come up with the software called latex?

[Funtasmia]

33:55 GET YOUR HAND OFF YOUR POCKET WHEN YOU ARE TALKING TO MR.DONALD! :D

[StoneCypher]

There is a single counterexample: zero.

There is no phrasing of 0 whose substrings may be added to any power of two (remember, 2^0 is 1, not 0.)

[StoneCypher]

@StoneCypher Er, with respect to the bit at 14:20 or so, about substrings of the binary representation of integers being at least in one form always summable to a power of two. Sorry about the loss of context.

Google Maps GPS coordinates used to work ...

[meterdatamanagement]

thanks for the wide spectrum

[carlostinonsa]

Oh I hope Donald is not having problems with his verbality, but damn, he's aging.

[Martyeffinmar]

I love him!

[lordjavathe3rd]

at 43 he started gloating about grandkids. They should have asked him how their shit smelled.

[lordjavathe3rd]

at about 16:47 I think his time has passed. Not that he isn't capable, but you can tell he has to exert mental effort when younger computer scientists do not. Interesting hearing from him though, I'll add that I'm not yet qualified to read and understand one of his books, but I don't think that takes away from what I said.

[tiftik]

@lordjavathe3rd

I disagree. It's probably just that Knuth doesn't have good verbal skills and has some hearing problems due to his age. Also, programming and computer science are entirely different things. Knuth is not really a great programmer, he probably doesn't know how the high-level implementations of things work today but none of these matter because computer science is a field in mathematics and Knuth is the god of that field.

[revtkatt]

Holy crap. Like being in his Mind.

What kind of shirt, also?

[adickel9]

easy way to get GPS on google maps... right click area you want coords for, click "whats here" ..check search bar at top

[Babarock87]

Donald fricking Knuth! Thanks so much Google!

[rbarraud]

@MrNightLifeLover I don't remember the bit about the weather...

[ZeqBarboza]

he is not nervous, he is old.

[fellonora]

so many macbook pros

[kevanmoran]

The phenomenon is known as someone thinking while talking. You've either never done a question and answer session or you are in sales ;)

[lordjavathe3rd]

@kevanmoran wow, you made me laugh in burst. *tips hat to you sir*

[PatrixCR]

Does Donald Knuth have trouble with speaking (illness) or is he just nervous?

[icosahedronman]

Don Knuth has done more in 1 lifetime than many others could have done in 10 lifetimes... Why does he seem so nervous ???

[ZeqBarboza]

@icosahedronman he is not nervous, he is old.

[fknwtf]

Wonder how the youtube closed captions algorithm would fare with this talk... ;-P

[beardymonger]

D. Knuth!!!! Google rules and amazes me more each day.

Google: Can we have some mathematicians? Conway explaining monster moonshine would really really make me weep in joy.

-just a fanboy

[paucarre]

It is strange to listen to God saying he is not going to talk about religion.

[arthas702]

His tongue is not able to follow his brain

[rbarraud]

@arthas702 Your comment doesn't show evidence of any engagement of yours...

[lennyhome]

Knuth is my homeboy

[nikolajl]

Donald Knuth is undoubtedly a living legend. However, the improv Q&A in this video is not the best format to show his genious. If you're not already a fan, this won't impress you.

[johnjaksic61]

@g9yuayon

Not nervous ---but very idiosyncratic

[johnjaksic61]

Truly brilliant----and many great insights!

[odyssey82]

If there were 10 people like me in the world, we wouldnt have time to read each others' books! :-) #AWESOMEQUOTE

[ericfontainejazz]

always want to get closer to the metal. Saves power and resources. Low-level programming will never die.

[g9yuayon]

Knuth looked really nervous, which was strange.

[pestlett]

@g9yuayon Watch his old videos from Stanford, especially the ones from his classes on problem solving, it's just the way he is. Even in small classes with a handful of students.

[bigbold2]

Donald frickin Knuth in the room and look at all the people still tapping away on their notebooks. What would it take? The Queen of England?

[someman7]

@bigbold2 You must be from england XD

[fleontrotsky]

@bigbold2 The Queen of England is interesting?

[manirkm1]

@bigbold2 Hope they were taking notes ;)

[athinggoinon]

@bigbold2 maybe they're taking notes.

[euphoria83y]

@bigbold2 not everybody has to share your reverence.

[euphoria83y]

@bigbold2 Not everyone has to share your reverence.

[warpr]

@bigbold2, maybe they're taking notes? :)

[jcookeman]

@bigbold2 Donald Knuth > Queen of England. That certainly won't work ;)

[pyrrho314]

@bigbold2 : lol, off with their laptops!

[nwb954]

@bigbold2

no

I think some might still be busy with the other tool that they have with a women around cs folks

[MrFrancoisBoucher]

@nwb954 certainly, you are not among them.

[bearchildofdeath]

@bigbold2 *cringes*

There is no Queen of England!

[patiencebear]

@bigbold2 Someone who gets a streight sentence out in less than two minutes I guess. He's a brilliant mathematic but after seeing this I wonder how bad his presenting style is during lectures.

[ivankaramasov]

@patiencebear He is not a brilliant mathematician. In fact, he has not made any contributions to mathematics as far as I know. He is a computer scientist. Although I have to say that he is just as bad a lecturer as some famous mathematicians.

[5998b]

LOL yes his comment about GPS coordinates and Google maps is perfect! Once I gave a helicopter pilot all the info I could get from google maps about where to drop my resupply package in remote location of California. This plan was foiled when he later told me Google maps and his GPS didn't work together. $15 per minute for a failed hour long flight... This speaker is wonderful over all.

[barryallard]

@5998b An audience member mentions there is a Labs features which shows GPS coordinate as a tooltip next to the mouse when pressing 'shift'. Granted this may only work on desktop browsers and does not mention which GPS reference ellipsoid coordinate mapping is used.
