Which is why it's so important to get an accurate description of the task at hand, up front.

In practice, quite often one cannot get such a description, and even might have no idea which sort of additional tasks are suddenly necessary later on.
Therefore, it is usually a good idea to have a "natural" representation of the given data in memory: Only by this one can expect that simple changes of the task require only simple changes of the program.
Quote:
it's perfectly simple to use a multi-dimensional array in awk in any case.

The fact that a matrix can relatively simply be emulated with an array does not mean that it is a good idea to use a language for a problem which does not provide the natural data type for that problem.
In fact, the code your posted is IMHO the perfect example to illustrate what I meant: Since the matrix is not a native data-type in awk, it was simpler for you to program 3 arrays manually instead of an n*3-matrix, and so the code must be rewriitten almost completely if the 3 changes to a much larger or dynamic number: The lack of the appropriate data type tempted you to write code which requires a major change under a minor change of the requirements.

Edit: Seeing all the other hacks with calling "tac" and/or calling the program multiple times and appending data when all this could have been simply arranged by a slight reodering of the loops of the perl code or adding some loop, I see my argument highly confirmed.

Nonsense; I merely followed the OPs approach to show how to do what he was trying to do.

As the X-Y problem illustrates, quite often that's not in fact what they want to be doing; but that depends on the task at hand.
More often than not, it's only a throwaway or a one-off specific to a situation, so why bother trying to deal with every conceivable situation, when you don't actually need to?
That's just wankery, to be blunt about it. Focus on the result, first of all, and keep it in mind.

Not your quest for self-confirmation, which is in fact just the usual delight in lumerence, the (neurological) payoff for our work.

You'd be a lot better at this, if you had some experience of the live-flow of IRC, rather than academia.

My apologies. I did not intend anything about you as a person, which "your quest for self-confirmation" clearly came across as; the "you" or "your" there is generic; I would have used "one's" but it feels very stilted to a modern English speaker.

What I mean about IRC, is simply that it has a different culture, one which is quite different to anything else I've come across; it purely is about the craft, in the channels I lurk in. There is no visual clue as to anything about someone, apart from their words. So far, the same as email lists or web-forums. What makes IRC so unique, is the combination of very quick (to the extent that it can be called "live") yet still async ("More like email than you imagine") chat, with a very large number of experts in whatever particular language, project or subject is at-hand.

There simply is no regard paid to anything such as "who you are", or "what your position is", unless you're flaunting ops which is considered bad-form: it's all about the work, and the result, for whoever is asking. Including where the questioner is clueless about how to get it done, and is asking all the wrong questions.
If status is involved, it is in the form of quiet respect for others who've taught you, or helped you to see things you simply had no clue about before. And they in turn were helped by others, so it's not about gathering "disciples" (or "padawans") either, except for a few fsckwits who quickly retreat to their own little corner.
It's not about gurus: at most it's about influences you've chosen, usually without telling them so, as hero-worship always leads to disillusionment.
Status comes from two things: knowledge, and ability to communicate in a manner that others find helpful. Nothing else.

This is very different to the office or university, where a hierarchy is in constant evidence, or indeed email lists and forums, where everyone knows who's wearing a badge, and clearly that notion of "being above" appeals to some to the extent that it's their primary motivation.

The "quest for self-confirmation" refers to the way it can often feel like everyone's conversation is effectively a variant of "validate me", in particular on IRC. OFC, one must apply it to oneself, or insight remains a notion, and never a reality.

It's quite easy for the IRC approach to come across as rude, when someone is not used to it; and the only way for them to realise that actually it was quite a compliment that you were so direct with them about what you thought, is for them to experience freenode for themselves; it takes a few weeks to acclimatise, so simply dipping in does not work.
And ofc, everyone has bad-hair days.

In any event, I would like it to make it clear to you that I have the highest regard for your work, not just on eix.
It's a shame you didn't take your transcendent hoc further, imo.

Sounds fair. It is more than once that a cause of our misunderstanding was actually linguistic.

I cannot judge; I simply cannot afford time for IRC. In fact, I spent also way too much time in this forum which is one of the reasons I do not proceed such discussions anymore.

I would consider your imagination about status/hierarchy as a major driving force of (good) researchers just funny, wouldn't there exist the tendency from some sides trying to force such ideas from economy into the research system, doing a lot of harm to research this way. But I do not like to waste more time to discuss this here where a discussion will not change anything (And this whole topic is OTW, anyway.)

Back to the main topic. IMHO everything important has been said, already. I consider it appropriate to give people hints how to solve their problems on their own. IMHO, recommending the most suitable programming language for a certain type of problems is an important point here, even if it is possible to write a solution for a particular problem in every language. And in my experience, one is always better off if one chooses the more powerful ("higher") language unless one has/expects certain restrictions which exclude this choice.

Sure; and my experience is that it's better to use the lowest-level language possible, which succinctly expresses what it is you want to achieve.
I must mention in passing that the thought of awk as a "low-level language" is very odd to me: it's a VHLL, and always has been. It's just very clean, and very quick.

The problem with kitchen-sink languages is that you don't really learn how to solve anything; do it in awk first and you have the algorithms worked out cleanly, using pretty simple operations. A bit like functional programming, you have expressed the essentials without any distraction.

Not to say you can use it for everything; but this use-case doesn't fall into that, imo. I've seen much more complex things get knocked up within half-an-hour in #awk.

The IRC thing is cultural; it's not my imagination that a) human-beings are social animals to whom status matters, nor b) that academics have little else, albeit derived from who's publishing what.
I think I'll post afresh about IRC, as it's a wider point that comes up a lot.

I mentioned it to you, as it seems like a shame to cut yourself off from the real cut-and-thrust, and indeed that whole approach, which is much more cogent.
So, I never said let's talk about how to change academia: merely that IRC is more useful, ime.

As ever, it's only chat. Thanks for your understanding.

While, if you use a high-level language, it is not a problem to use (up to small syntactical changes) the same code as for a lower level language, you might be forced to reimplement everything if the specifications change slightly.

The data types it supports are very poor.

I don't agree. Just because you can use convenient shortcuts instead of writing lengthy routine code does not mean that one cannot understand what is going on. In our particular exmaple, BTW, I did not use any trick "map" operands or other shortcuts but wrote loops very explicit.
Quote:

This is not true if you do not have the data represented naturally, internally. In our particular problem, the array structure of the problem was very natural (somebody even mentioned natural array operations like transposition).
Quote:

It is comparing apples with oranges. Solving a problem which a specialist can do in a few minutes, and for which essentially all required tools already exist, is one thing. Research involves more working on problems which take months or years for many good specialists, and which are perhaps not solvable at all. It is too short-sighted if you try to measure the latter in terms of direct applicability/"usefulness". I am clearly a researcher and spend my time correspondingly.

It's got nothing to do with what you're doing, and everything to do with the manner in which others deal with you, and each other.
The "cut and thrust" of academia I heard so much about before I got there, turns out to be rather limp and anodyne by comparison.

I understand what you mean about long research, really I do. It's irrelevant nonetheless; I've actually found much more useful information and much more depth of experience on IRC, than in academia.
Academics tend to be good at all the usual political crap you see in the office, just couched under a differently-coated layer of bulshytt; it still smells though. Inevitable when they live or die by their level of research funding, acquiring which has very little to do with anything related to their subject, other than how much it can be exploited for private profit; a factor which has very little to do with who actually gets the funding.
The higher up that hierarchy you go, the more research-funding, acquiring it and holding on to it, and acquiring the next round, is the motivation.

The issue with that, is that it leads to the usual hierarchy of aptitude at the wrong things. "Specialists" are not what you get, at all.
Nor are good teachers. Both of which are to be found in far greater proportion on IRC, at least ime.

Though there are quite a few academics on IRC; in particular in ##math (which is full of LaTeX symbols) and #haskell. Similarly there are academics who know what they're doing, such as yourself, and a couple I've met along the way. They tend to be quite good at teaching as well, because they have a love for their subject as well as competence, both of which students pick up on and respond to positively.
In that context as so many others though, the exceptions tend to prove the rule; certainly from the perspective of a probabilist.

Sure, if your question is of the type "How do I solve this-and-that particular problem/do this task/repair that thing" or you want a working code snippet. Not if you want some deep understanding and progress in fundamentals, which - as a rule - are topics which have no direct application and cannot be solved in a discussion but need long thinking and eventually ingenious ideas (which sometimes come after many months if you do nothing else...). That's why I say: Comparing "usefulness" of such completely different things is comparing apples with oranges.
Quote:

At least here, it happened only in the recent 10-20 years that funding took such a dominant role. Fortunately, there are still some positions where researchers are free as it should be. And there are still many grants about which qualified researchers decide instead of only private interests. So not all is lost, yet.
Quote:

All researchers I know are aware of this problem. No doubt that the tendency was going into the wrong direction for far too long already, and this should ought to change. But as already mentioned: This forum is not the correct place for such a discussion.

No. That's simply your opinion based on zero experience of what you are discussing; or so little as to count as zero: in fact likely to be the wrong kind of (negative) experience if you've only dipped your toes in.

If what you said were true, then there would be no point in academia either: no reason to gather bright minds together and facilitate discussion at such great expense.
IRC simply does that much faster, and cuts out much of the irrelevance, such as who's greased one's way up to what office, or what someone looks like.
Quote:

My point is that ignoring the actual pretext, or more accurately raison d'être, for academia, and then pretending it doesn't matter when it does so badly at it, it's still so much "better" for deep research and thinking than that awful IRC with its irreverence and direct approach to bulshytt, is a flawed decision.

Whether someone uses IRC to talk nonsense, is about as on-point as whether students piss away their time at Uni.
The simple truth is that neither is required for deep-thinking; but discussion and collaboration are another matter.

I wanted to ask: have you read Kuhn's "The Structure of Scientific Social Revolutions"? (auf Deutsch, natürlich.) It's much harder to read in English than it needs to be, but it's feasible if you already have German. (at least, the translation I read, several decades ago.)

That's where we get the notion of "paradigm" and "paradigm shift" from, and it's the pretext for an academia so mired in mediocrity (not generalists, and certainly not specialists in the field, rather micro-specialists who have no breadth); but whilst Kuhn's analysis was fine, his synthesis (conclusion) was a pile of self-serving horse manure (much like most legal "decisions.")

Note I am not saying there is no place for universities, though it is sad that they are effectively teaching what should have been taught at school, to compensate for the asset stripping of the public sector that underlies so much "private success".

Thinking is a rather lonely process. In the ideal case academia provides the infrastructure needed for this, that is - most important - the necessary time and (relative) freedom from unrelated obligations, access to information, etc. Personal discussion is just one (relatively minor) point in this infrastructure, which is useful only in certain stages. It is not accidental that the most important form of communication in academia happens in form of publishing (refereed) results. IRC can in the best case be a very poor substitute for some personal discussion on some specialiized meetings - inferior in almost any aspect - and even the latter has usually only value in those rare cases when it inspires something which happens afterwards alone.

You really believe you need an "infrastructure" to enable thinking?

Actually this comes back to the status game: the publishing of papers is what you are judged by; and nowadays on how much research funding you pull in.

There is no need for "infrastructure" as you put it, to publish. Or we wouldn't have any of Einstein's work, nor Tesla's, nor Fuller's.

In the main, what one needs is review from people who understand what you are on about, and to have sloppy thinking pointed out as such.
And ofc to be exposed to things you would never even have dreamt of.

I accept one needs time free from distraction; but you can get that in a field. And it's hardly unique to "academic" subjects; music and art require the same, though music requires other people in a way that art, and the "harder", supposedly scientific subjects do not.

Ah, I see; you are blinkered, and enjoy the blinkers.

You're right, not much point in this discussion. Blind assertions with no substance backing them up, do not an argument make. And this has gone beyond discussion into precisely that realm.

So let me fire a bit off too:

Academia is even less efficient than most offices, which is saying something, even more hidebound than a museum, and as tradition-obsessed as organised religion.
That's what happens when all one has is status: you make out like it's a lot more important than it really is.

Sure. As I mentioned: Mainly time/freedom, access to information, also personal contacts with specialist in your and other fields, ... not to forget the initial training and introduction into a field which you can better from a lecture than from any book.

You are confusing cause and effect: If you want to play the economy game and measure the quality (and this wish comes only from outside academia), then you are led to the publications as a "natural" quality criterion. Undoubtfully this economic invasion has many negative effects. But this does not change what I said above that the publishing of results is almost the only possibly way to get progress in (mathematical oriented) science, and it is still the most important way of communication in science.
Quote:

To stay with the Einstein example: If Einstein would have worked in a firm in current economy instead of an historical post office: I am sure we wouldn't have any of Einstein's work (at least not from Einstein). And if Einstein wouldn't have later on enjoyed some academical freedom and with contact to excellent mathematicians, we also surely wouldn't have more than special relativity (at least not from Einstein), since e.g. general relativity (as many other deep subjects) does not only require some ideas but also simply "work" (with a lot of knowledge which you will never get in a post office).
Quote:

Maybe you are lucky and have a job where you have this possibility - I do not know any such job in my country except if you are born rich or devoted many years of your life to get rich; in the latter case you most likely had already to sacrifice your most productive period and will have difficulties to get back into some real deep subject. In academia you get a non-trivial amount of time specifically devoted to it - to my knowledge that's really unique.

Sure. In many aspects, there is not much difference between science and art.
Quote:

I am not sure whether I understand you correctly. Many (perhaps even most) mathematicians I know are musicians, many even professional ones.
Quote:

That's a problem with such general discussions. The topic you want to talk about is social sciences. This is not my field of interest for various reasons. One of them is that most assertions in these field are in principle speculations based on various experiences. There is nothing which can really be proved. (And no: Statistics is not a proof of any abtract claim either.)
Quote:
Academia is even less efficient than most offices

To quote you: Please, stop talking about what you simply do not know about enough.
Sure, there's many problem in academia, especially in the last years, but they usually come from outside: A tremendous shortening of necessary money (e.g. in many institutes the number of permanent scientific positions has decreased from 30-40 to 5-7), in some countries (AFAIK less so in the states) in the increasing role of administration (which in a sense is also an outside cause), and some other. But that perhaps the sysetm is currently about to be broken by short-sighted people from outside, does not mean that the system was bad. I am afraid that the system of academy as we know it now (still) will cease to exist in some 10-30 years, and consequentlsy science (as we know it now) will do so either, soon after. Probably, this is not the first time that thiis happens in history of mankind.

I came back online to apologise, so let me do that; the "blinkered and enjoying the view" quip was shameful.

I was reacting to what I perceived as denigration of IRC, by proceeding to denigrate academia, which as I stated earlier, I am not trying to deny altogether.

I am sorry for that.

In effect I have been decrying the same "commercialisation" or more accurately imo, selling-out, of its principles that you have described.
But I'll come back to this tomorrow, when I'm not feeling quite so chagrined.

What I should have said wrt Kuhn, was simply explain what I found so crappy about his synthesis.

His analysis, briefly, is about how "society" (by which he ofc means white landowning men) focusses on one overarching idea or metaphor to explain how things work, to the exclusion of others. Including to the extent of ignoring evidence which does not conform to expectation (or "fit the theory".)
An example would be the "elements" Earth, Air Fire and Water, or in medicine, the notion of "humours" which only leeches can remove from the body, both of which were considered "science" for many centuries in the West.

This is the "paradigm" so beloved of "modern" executives, who really do not understand what it means.

Kuhn outlines how the paradigm is explored, until it breaks down, due to evidence that can no longer be ignored: it no longer fits the facts, or explains everything, so a new theory must be devised. This would be the "paradigm shift" that sounds so funky; if only people knew what it meant..
OFC this is down to the great theorists in his write-up, and not down to the people exploring the field.

The problem is that he then drops in a complete non-sequitur in his synthesis, in effect: "that's all right, then."
Like so many "seminal" books I have read, the author is actually seeking to endorse the status quo, however nonsensical.

He does this on the basis that this is "how things have always worked" (in the last few thousand years of patriarchy), and using as justification the fact that the theory is eventually overturned: so the fact that we've been ignoring evidence that doesn't fit our model, is not as one might think, bad science, but in fact good science.

AFAIC this is simply horse-shit. Yet this has formed the pretext for making everyone explore solely one area, and in modern times to encourage doctoral students with "Don't worry: just find one tiny result, so we can say you've added to the sum of human knowledge," and then you'll have your PhD, and be "one of us"; YAF waste of space.

It is a criminal waste of talent, imo, to set the bar so low, and essentially to involve your students in a fraud.
Mostly though it is terrible science.

So nowadays we occasionally hear of a "multi-paradigm" approach if someone is feeling terribly clever, or more commonly "multi-disciplinary" which is not the same thing, although it does at least bring different perspectives to bear.

Nonetheless, the underlying basis of Western Science, as practised over the last 3-400 years, is simply untenable.
And this is where academia derives its pretext from, since it is no longer about cloistering away the autistic sons of privilege, along with the child-abusers, so that the psychopaths and sociopaths can get on with beating up on the serfs, and making sure no-one remembers that the Communal Weald ever existed, even though it still does.
(The cloister comes from the monastery, so before you take exception to the above, consider the history of the Western Church, the basis of the Establishment, which was the sole Power for the majority of the last 2000 years, and more in other cultures.)

We see a similar thing in computing, with the drive for One True Way, which was debunked 50 years ago, but still rears its ugly head.
Monocultures do not work. They always fall down, because they are trying to pretend that reality can be handled with just the one, usually dumbass, mode of thought.

Law Zero of Modelling is: The Model is NOT the reality. One reality, with many aspects, and infinite perceptions thereof.

Similarly, computing is an ecosystem, and experience has shown we are best served when we allow for multiple modes of thought; it is in fact far better to use several languages, than solely one, however much we want to feel "on top" of everything, and thus push for inturgration. Often switching language allows you to approach the problem in a fundamentally different manner, as you focus on a different aspect encouraged by the mode of thought implicit.

I can't find the precise Kernighan quote I want on this, atm, just several others; but I will at some point, and stick it in the bot. ;-)

You say this is all Social Sciences; what you're missing is that this "social" science is precisely the basis for academia.

Further Natural Philosophers never confined themselves to one, narrow frame of reference. Neither should you and I, when discussing things like academia and Science, as opposed to a specific computing problem.

Thanks for the link on Lucio Russo. He seemed to be getting at the same thing, really: explore everything, and don't pretend you can understand it all.
Though the notion that science was "born" in 300BC is ofc complete twaddle. It may be convenient to forget the billions of years of evolution before hand, or the fact that there have been civilisations long before, going back hundreds of thousands of years, and indeed the burning of Constantinople was very useful in terms of burying history.
Nonetheless it remains a lie. Science is simply a common-sense approach to the world: if it works, use it. If it doesn't, then no amount of self-rationalisation will make it work.
While people like to talk about sciento (if they dig into the basis), in fact the underlying idea of Science, is that we do not know.
You'd never guess that from the pontificating and chest-puffing that goes on around it, though.

Please don't take my critique of the basis to imply an attack on everyone and everything. It is not.
It is solely a critique of the hegemony, which is without fail full of crap, ime.

Thanks for your explanations. It makes clear that what you mean by "academia" is a much wider definition than what I meant: I was mainly focussing on mathematical academia (with certain large parts of computer science as a subfield - though officially usually independent); e.g. I would perhaps not even consider modelling as part of this field. And in this field "paradigm shift" is really not a topic: The field has the advantage that you can decide about correctness in an objective way. Only what you consider "interesting" is subjective and might be different in a few decades (if science should survive that long...)
My experience is that good students are not "wasted" by letting them improve only tiny steps. Good students and teachers change subject if they realize that they run into the danger of obtaining not more. Of course, not all students are brilliant, and somehow one has to deal with this fact, too (e.g. throw them out or let them learn with simple things, first).

Concerning Russo, I think there are some misunderstandings; he is mainly a historian (though also mathematician and physicist). Perhaps you should read his book (AFAIK, it is translated into English). First, it is very important to understand what Russo means by "science": He gives a very precise definition of it. (A very brief and not precise summary: The crucial part is the abstraction process into some theory and to proceed with a systematic study of this theory. In contrast to "empirics" which consists in measuring and "observing" certain rules, only. For instance, the process of determining the radius of the earth by having a certain model of earth and sun, which was developed at around 300BC, is an example of "science", while calculating a table for tides by extrapolating previously observed periodicities is "empirics". The crucial difference is that the former requires a theory which can lead to results far outside of the scope of the original measurement)
Russo argues with many reasonable references that at ~300BC science in the sense of this definition did evolve (he does not claim that it evolved out of nothing; in fact, he describes also the earlier history of many ideas in detail). He does not go back much longer in history (I guess due to lack of available sources which hint reliably to the scientific level), but his crucial point is not the raise of science, but more the question which level has been reached and what was after this:
After science has reached a tremendously high level within a few hundred years (some things being reinvented - even partially with the help of some original sources - in 20th century, only), it rapidly decayed and has practically completely vanished for many hundred years: Even the basic understanding, what a theory is and why it is important, was lost. All serious scientific books of the high time of science were lost, because they could no longer be understood und thus were not considered valuable. Only very few books survived or were copied for random (non-scientific) reasons. For instance, Russo explains very reasonable that Euclid's "Elements" are comparable with nowaday's text books in calculus: Just teaching of some very basic technical skills, but not comparable in level with scientific texts of the same time.
Russo gives also historical reasons for this tremendous loss of knowledge and of practically the complete destryoing of scientific achievement. Many parallels to today are frightening

The books were not lost but destroyed. There are not many reasons to find but one:

Both; not all books have been in libraries. Russo gives in his book also exhaustive references on this aspect, perhaps more than on the Wikipedia page.
The most frightening parallel to today (besides other reasons like slavery of scientists which are only partially parallel :wink: ) is that only the theory was destroyed/considered as unvaluable:The economic effects of science like machines and building techniques were kept for a rather long time, until the lack of theory and understanding of the underlying principles for the construction (and the inability to understand the texts without any idea about theory and the scientific principle) eventually led to the situation that the machines could no longer be built/repaired. In later centuries these machines were then considered as miracles and legends or working through magic. Also here, Russo cites very illuminating references describing these miraculous machines which is what stories like Indiana Jones took over many centuries later...
