Folland is great, but no I am not talking about school books but undergrad books. Books by AMS, Springer are usually great. Some of the common trashy books are by Pearsons, Cengage etc, although Folland's calculus was probably published by pearsons

Consider a simple embedding of words into a 'vector' of dimension d.

One can, however, homogenize it by adding an extra dimension such that the first d dimension catches only the sense of the word and that extra dimension indexes through its synonyms. The sense being the common projective shadow of those words.

The undergrad books not so much. There are tons of colorful padding. Pages after pages that describe what the next set of pages will describe, advertisement for apps and websites. In fact good 10% of the pages/area seem like marketing copies.

It seems like the publishers feel guilty about charging how much they do and try to add bulk in weight and volume to make the customers feel not so bad -- sugarcoat the rip off somewhat.

Sometimes it is so frustrating that it makes me want to yell -- stop faffing around and get on with it.

Gotta mention Lindsey Buckingham.

(Way underrated)

Cool gadget indeed !

This topic has been done to death on HN. Now I am getting tired of this. Can we have some other content in HN front page please.

I do not remember such a long period on HN where I haven't found a HN front page story interesting enough to bookmark or upvote or comment in.

Wish the text tiles were not so intrusive and obstructive.

Who wants a pretty view occluded by a large white rectangle!

Then there was that circumcision disagreement.

Absurd levels of inefficiencies are also good opportunities to make contributions. In practice this fraught because many of those are somebody else's moat.

For swift colorful pigs that flit in and out of thick bushes making complex yet signature grunting sounds, yes, I think that would work.

The outcry is understandable but as long as this was an authorised operation it fits the constraints. Who would let go of such an opportunity ?

Not conducive for trust though, which I assume had long vanished anyway.

Well, we are talking about US border patrol folks. Trust me, they are the nicest guys around /s.

Cannot confirm because I am on Chrome. But it would be so sad if that website is Chrome only. I doubt it though.

Can other browser users chime in.

Regarding the Dutch intelligence officials (in fact regardless of their country), targeted and legally authorised information collection is fine. That is what intelligence agencies are supposed to do. "Trust but verify", and all that.

It's blanket surveillance, unauthorised surveillance that crosses the line.

Which luminant objects are real and which are artistic license?

Would not plate solving with each choice give different results.

No guessing needed for Escher's stars. He had a love for astronomy that shows up in some of his works.

The story of the third paper:

Bose had sent Einstein a follow-up work after his second submission to him on thermal equilibrium of matter and radiation. The second paper had been published but along with Einstein's takedown. This seems to have mortified Bose. He was expecting a personal review and rejection from publication of a paper that has been judged faulty. The third paper, presumably addressed the objections.

Einstein, however, remained unconvinced and did not arrange for its publication.

This third submission is lost.

I find SN Bose's derivation of quantized distribution of energy levels so much more elegant than Plank's which reads more like a desperate hack to force a predetermined answer.

Where are they priced like that ? Very curious.

Paracetamol is in general safer than ibuprofen unless you are allergic to paracetamol, in which case the result can be quite gruesome and bloody.

Paracetamol is not a blood thinner. There are not many OTC painkillers that are not blood thinners.

More flexible and permissive a language the easier it is to abuse. Tcl is both very flexible and permissive.

I know.

I would hazard a guess that a significant fraction of HNers would have encountered TCL in silicon CAD and took with them a frustrating experience.

Very interesting. I was not aware at all that this was an Indianism. One that I like quite a bit is the word prepone.

You can find yourself having to work with quite unprofessionally written code. Not an uncommon experience.

Are you sure ? Tcl is almost a decade older than javascript although subinterpreters came later. Even before subinterpreters you could have multiple Tcl interpreter instances in your code.

One could call Tcl_CreateInterp() multiple times in your code and each call would return an independent interpreter.

Would this be the best place to learn about it

To be a good performance optimize yes,you need to have done it a few times to be good at it and have acquired not just the skill but the discipline and taste.

More than having done it a few times though, what is more important is to have thrived in a space that is welcoming of intellectual curiosity and play in matters of performance. That's how one becomes good at it.

Not to mention uplevels and upvar.

I have a soft corner for TCL, because of its idiosyncracies and weird dynamic stringy playfulness. I would be wary of using it professionally but to play around for the fun of it ... it's just too much fun. Upvar and uplevels are crazy.

Python is that kind of cool one behaves when visiting parents of your would be spouse for the first time. Tcl on the other hand is like playing one's secret exclusive and somewhat dangerous games with kid school bestie.

Tcl/Tk pioneered the notion of a scripting language as a library. It got threading right. You can run multiple independent Tcl interpreters in the address space of your process and they can exchange messages. Entirety of interpreter state is encapsulated inside the interpreter object, no globals. To a user an it is just a pointer to an object.

No need for GIL, no need for serialization/deserialization (pickle/unpickle) ... just within process memory copy (or no copies in case data is immutable).

And how would that staff have learned it ?
