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…

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&…

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 …

> 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 …

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 prefe…

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

I am bent the other way. I am very vigilant of whether I am sucking up to anyone. So in one of my first grad school conferences I see this stalwart professor making his way through different poster pr…

> 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. T…

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…

That was my guess anyhow. A common affliction among newly minted PhDs. They usually out grow it. I am reminded of https://news.ycombinator.com/user?id=almostgotcaught Won't be su…

What's with this phenomenon of new accounts that confidently make authoritative false claims in things that they have no competence in. Few days ago there was this account claiming there's n…

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…

https://64.media.tumblr.com/32cb3be24eb46c26ffcaea9bbebc1c62... Allow me to rubbish your claim. It's a common use.…

I wonder if it's his Maths teacher that Onfim is killing while sar on a horse.

Of course to measure out 42 litres from two jugs of 5 and 17 litres each on the day that the Sun is in the exact same position among the constellations as today, and so is the Moon and in the same pha…

> I've read that Al-Khwarizmi's book on algebra [0] contained no equations or even any numerals Yes the use of symbols came much later. Algebra used to be couched in terms of do this to …

Does progressive jpgs do the same thing?

> Presumably people were doing _something_ in 13th century math classes? What were they doing? Glad you asked. This is what one such endearing 13th century kid was doing in class https://…

I have mixed feelings about this. BTW my comment is not about Axler's linear algebra book but math pedagogy in general. Spoon feeding doesn't really help with learning, internalising, buildi…

I don't know enough to know why, but they were very interested in the extremes of size, both large and small, as well as the notion of infinite. Fascination with the large seems to be a pan-cul…

> Fibonacci did not, however, discover the sequence – it was recorded in Sanskrit at least as far back as 200 BC. Possibly even earlier. This is not developed further because the article is about L…

I did not know of Poleni, thanks for that story. I always thought that the notable insight was by Robert Hooked. Oh wait I misread, it was Robert Hooke as you said, but Poleni used and developed it. I…

> a good fit on one problem, made with a universal approximator, is not an explanation. It can be just a compressed description, I couldn't have said it better.

He is solving differential equations but with an analogue computer. Doing it faster and with less doubts over fidelity and existence of a solution too. Solving partial differential equations numeric…

Relatedly, a common confusion is the use of probability in ergodic and non ergodic processes. The best example I have come across is that of a million people playing Russian Roulette with a six chambe…

What happens to systems such as Spanner under these circumstances? Is it a headache or a non-issue

I am waiting for folks to confirm that pulling them off machines designated for the landfills was a thing.

I have forever been confused by 'left' and 'right'. It takes me a few seconds of deliberate thinking to get it right. So in one of my first piece of software that I wrote for real …

Now to rip RAM off PCs being sent to the landfills.
