Holy cow, I finally finished writing up my notes, @shapr and @kingcons , after all this time!

#Theory, #RichardHamming

Im Blog suchte jemand nach "Humming". Ich vermute es war "#Hamming" gemeint. Aber auch dazu habe ich noch nichts geschrieben. Es handelt sich um so eine Art "bessere Prüfziffer" oder auch "aufgemotzte Parität".

Neben der Entdeckung eines Fehlers kann man damit auch Fehler korrigieren

Anti-Gravity, Time Travel, and Teleportation: Dr. Hamming Gives Advice

You may not know the name [Richard Hamming], but you definitely use some of his work. While working for Bell Labs, he developed Hamming codes -- the parent of a class of codes that detect, and sometimes correct, errors in everything from error-correcting memory to hard drives. He also worked on the Manhattan Project and was a lecturer at the Naval Postgraduate school.

Turns out [Hamming] has an entire class from the 1990s on YouTube and if you are interested in coding theory or several other topics, you could do worse than watch some of them. However, those videos aren't what attracted me to the lectures. As the last lecture of his course, [Hamming] used to give a talk called "You and Your Research" and you can see one of the times he delivered it in the video below. You might think that it won't apply to you because you aren't a professional academic or researcher, but don't be too quick to judge.

Turns out, [Hamming's] advice -- even by his own admission -- is pretty general purpose for your career or even your life. His premise: As far as we know, you have one life to live, so why shouldn't it be a worthwhile one by your definition of worthwhile.

Along the way, he has an odd combination of personal philosophy, advice for approaching technical problems, and survival skills for working with others. If you are in the field, you'll probably recognize at least some of the names he drops and you'll find some of this technical advice useful. But even if you aren't, you'll come away with something. Some of it seems like common sense, but it is different, somehow, to hear it spoken out loud. For example:

If you don't work on important problems, it's not likely that you'll do important work.

One piece of technical advice? Don't waste time working on problems you have no way to attack. He points out that anti-gravity, time travel, and teleportation would be very lucrative. But why work on them when there appears to be no way to even remotely accomplish them today. Well, at least when he said that. There has been a little progress on a form of teleportation, but that wasn't what he was talking about anyway.

While not a hack in the traditional sense, examining your life, career, and technical research to improve your own effectiveness is something to take seriously. We were hoping he would throw in a joke about error-correcting your career, but unless we blinked, no such luck.

Hamming's work on block codes was followed about ten years later by the Reed-Solomon code which is found nearly everywhere now. Hamming is also associated with the term "hamming distance," something we talked about when discussing Gray code.
