It has less to do with age and more to do with mental state. If you are happy, in the flushes of love, feeling safe, many things, even ordinary things will feel amusing, funny, worthy of a belly laugh. On the other hand if you are stressed,

It's a good book on what it is about but Foundations of Data Science it is not. It is very narrowly focused on the authors' research interest around theoretical results on spectral approximations. I find their work very interestin

As an Indian and an avid traveller I would welcome such a step. So many places in India have been reduced to a shit show of filth because of not drawing a line. Many places use an adaptive system of tickets/permits to keep tourist attr

That's a very orthogonal issue. Sparse arrays are supported on C libraries too. I have done my time with CSC and CSR even inside Python that called out to C libraries.

by srean 3mo ago
Honestly, I quite like Python most of the time. The times when I don't, argghh type errors. The worst I have had in a while is when I was dealing with a sparse array data type and getting some processing done in a C function to speed

Very interesting. Does LFortran have the same internal array layout as the standard C runtime ? A shared layout and a shared calling convention would be very nice. Sorry about my naive question. Haven't touched Fortran directly in thre

If one wants to add the capability to reason about shape and shape compatibility, Barry Jay's FiSh would be an interesting detour. https://web.archive.org/web/20111015133833/http://www-staff.... Thi

To add to the confusion, Mathematicians and Physicists often disagree on what that word means. A Physicist's tensor is often a mathematicians tensor field. An appropriate tensor can certainly be represented by a multidimensional array

by srean 3mo ago
> A tensor is nothing but a flat array of numbers, plus some metadata telling you how to interpret those numbers as a multi-dimensional object. Erm... many would disagree. I think what he means is just a multidimensional array.

Difficult to answer because I find some of the machinations so distressing. Perhaps it is the way I am wired. Given the benefits of the knowledge that became apparent later in life, I might have preferred looking on from a distance to under

Ah ! Makes sense. Those places seemed quite toxic and I kept my distance from those.

> unwritten rules of social play are learned in the process of growing-up. Could you elaborate. Under which circumstances does one learn these things. Family, surely not. I hope so.

Yes. It sure would have helped with my learning curve. Coming from a home and a college where it was ok to criticize or examine ideas openly, it took me a while to figure out what was I doing wrong. There is a big cultural aspects too. This

Sadly Arunachal is quickly becoming piss pit despite the fact that you need permits to visit. Same for Kedarnath. Permits need to be issued with the carrying capacity of the land in mind. Bhutan seems to pull this off well.

I mostly agree. I wouldn't have liked Axler as my first book of linear algebra but as a second book, it worked, it gave me a more algebraic appreciation which is a bit against my natural grain of vector space and geometric way of think
