tiffanyg··on Among the A.I. doomsayers
This is the kind of arrogant ~rationalizing / 'reasoning' that is my daily tell-tale as the ship approaches the leeward shore.
tiffanyg··on First new U.S. nuclear reactor since 2016 is now in operation
Not unreasonable, but I would point out two options (not the only):

1) "Water batteries" - highly efficient (far more than the 'chemical' you are apparently referring to) & responsive

2) Methods for using 'renewables' to produce &/ support production of chemical fuels - with the added draw / potential goal of 'closing' the 'carbon cycle'

As to #2, one of the ideals that has been kicked around for decades is to do something like: use 'renewables' to sequester CO2 from the atmosphere and convert it into something like butanol, for example.

Now, last I was up-to-date on any of this sort of work (~10+ years ago), the economics were not favorable. Certain types of commodity chemical production with 'biological basis' (another type of renewable, typically) had much more favorable properties economically. And, indeed, you do see, for example, (thermo)plastic products made from chemicals like "PLA" increasingly. But, the "biofuels" concept is / was much more challenging, especially as "fracking" technology made great leaps etc.

Nuclear has its pros and cons - blanket disavowal is fatuous. Nevertheless, there are substantially more options, systems, technologies, etc. in development and production than are often discussed in too many of the pro-nuke(s) / no nuke(s) 'sniping' chains that have been prevalent in society & on the internet since I was a wee tyke myself.

Now that is the kind of "modern problems require modern solutions" thinking I like to see!

Kudos - excellent examination of implications / change of perspective / viewing from another angle.

The kind of thinking that, more seriously, really can be essential in developing insight(s) etc. ... and, finding (proofs by) contradiction(s) etc.

I believe the solution was given by the great philosopher Pratchett*:

"Wen considered the nature of time and understood that the universe is, instant by instant, recreated anew. Therefore, he understood, there is in truth no past, only a memory of the past. Blink your eyes, and the world you see next did not exist when you closed them. Therefore, he said, the only appropriate state of the mind is surprise. The only appropriate state of the heart is joy. The sky you see now, you have never seen before. The perfect moment is now. Be glad of it."

- Terry Pratchett

(from Thief of Time - a remarkable book, IMO)

I'd be more impressed if it were that case that 0% of the WORDS remain.

Nevertheless, the consonance of this 'weaker result' is still satisfying.

Bravo!

tiffanyg··on The average store size in the US is the smallest it's been in at least 17 years
Funny - I was just thinking* about some of what you've described. In my book, a great deal of what a certain group of predators and naive individuals consider "capitalism" is hollowed of its core. Hollowed of aspects those who truly understand and have faith and respect for capitalism - well-founded faith and respect - generally consider essential.

People like Warren Buffett and Charlie Munger are / were far closer to sound / faithful capitalists than most seem to be, lately:

But, one can go further, IMO:

https://link.springer.com/article/10.1007/s10551-020-04521-5

Those who stress the idea that "greed is good" set themselves (and, unfortunately, the rest of us, as well) up for misery and the kinds of instability / inequality / tightrope walk that may culminate in events like the Reign of Terror (one example that always comes to my mind, at least - a la Les Misérables, for example [but, so much more than 'just' that theatrical version of events]).

https://eandt.theiet.org/2018/05/24/top-10-invasive-species-...

My favorite move, in God's** (actual) 4D chess game (playing off our ... tendencies, say), is when we try to introduce a species to get some benefit / value from it ...

https://fyi.extension.wisc.edu/spongymothinwisconsin/history...

... then, think - "gee, that worked so well, let's introduce a different species to try and undo the damage!" ...

https://www.science.org/content/article/biological-control-b...

There are plenty of further examples where attempts to remove invasive species have backfired in other ways as well...

But, ya gotta admire that indefatigable optimism!

To be fair and try for a degree of accuracy, we have obviously benefited, in the short term, greatly from technology, engineering, science, etc. ... But, there are certain areas where we do have an abysmal track record. Just about anything abstractly related to the so-called "gray goo" scenario being a prime example. Just like that recursive function you're SURE is limited no matter preconditions ... that takes down one of the main university computer systems the first time it's run... (back in the ol' days when there were fewer 'protectives' [codpieces being out of style even at that time ;)])

Sorry for low content response, but, too good a joke to simply upvote, IMO

tiffanyg··on Painting is Terribly Difficult
Hey now, how can you guarantee p(Picasso) or p(Hendrix) is 0 for all readers of your comment?*

In any case, I think your response and multiple similar responses make the essential point(s). One of the useful 'results' from decades of R&D at trying to build machines (&/ "software" - may be considered another type of machine) has been 'seeing' the difficulty in practice at achieving capabilities we (and many other animals ... even, say, nematodes**) absolutely take for granted.

One of the old jokes I always associate with Groucho Marx is something like:

"Can you play the piano?" ... "I don't know, I've never tried"

It reminds me of how people often say "foreign languages are difficult" ... As though any "native language" is somehow different / easy / easier ... Entirely neglecting the tens of thousands of hours of experience and practice most people have with some "native language" by the time they're a mere 10 years old. AND, we all continue to "practice" whatever language we speak and think (to some degree) in every hour of every day.

It's all in what you put your time into, as you get at, as well. And, one particularly crucial aspect is what you believe about how skill "arises" which you reference as well. One of the greatest disservices to (young, especially) people is inculcating them with the idea of "talent." While most people are not likely capable of becoming, say, the top tennis player (male / female) in the world - there are all sorts of variables - too often people are artificially limited by nonsense that passes as "common wisdom" and permeates "culture" (ideas that just propagate from some people to others - here, especially, parents to children).

It's interesting, to me, that while my mom, for example, was an incredible "believer" in education, and had defied her own parents and exceeded the role(s) they envisioned for her by many orders of magnitude, she also would often reference "talent" in various contexts when I was growing up.

We are riddled with nonsense - in our heads. I know for sure that I'll always be full of internal inconsistencies and false beliefs and the like. But, it is very helpful to escape as many of them as possible. Particularly those that artificially constrain us - a species limited enough as-is.***

** See recent articles on mapping of "neural network" / nervous system structure of C. elegans, for example

*** I write this not to disparage our species but simply to highlight the fact that we are constrained just like all other species by our form(s) and what is optimized by the process of natural selection and such ...

tiffanyg··on Nuclear Reactor Simulator
Excellent point - you are 100% correct, parent comment etc. were specifically about water-moderated types.

I was too grabbed by some of the later description and just connected it somewhat haphazardly to not very organized or accurate info rattling around in my head from years ago.

Thanks for pointing that out!

tiffanyg··on Russell's Paradox of ghostwriters
It used to happen much more in the past. Many decades ago, AFAIK, at least in the journals / fields / areas I'm familiar with.

I'm not sure where that might happen or be tolerated, today. If you go back and look at research into antibiotics, DNA, etc. back in the 1940s and 1950s ... and even research in the 1960s and 1970s, decades later, there ended up being serious questions around ethics, authorship, etc. for some really seminal papers, for example.

tiffanyg··on Nuclear Reactor Simulator
Thank you so much for sharing that! Beautiful / elegant and simple!

It's been decades since I looked at any of the details involved in any of the various types of reactors that have been designed. When I did, in the past, I hadn't even encountered concepts like "control theory" or spent any time with the subject matter of "systems engineering" or even "chemical engineering". I.e., areas where you start thinking about how to combine all of the different simple "laws"* and properties and such of energy and matter to create "robust" (ideally) or even just practical "systems".

Although I had read about the Chernobyl disaster, and "run-away" that occurred - the massive volumes of water being pumped in, partly as a result of such levels, at near boiling ... the steam voids, etc. I'm not entirely sure whether I really encountered the point about temperature and density, but, certainly, it didn't 'click' quite the way it did now when I read your description.

I love this kind of stuff - the "how it all fits together" from what can otherwise be these seemingly dry / 'dead' "laws" and such that can seem too simple / narrow / etc. to do much of use with - even if your teachers spend as much time as possible giving you homework questions etc. that certainly seem practice-oriented - but who gives a rat's-keister about whether comparing the weight of a duck to a putative witch might establish flammability and hence witchcraft when they're 15, right? ;)

* Simplified models describing various types of matter and physical processes - models that are valid (for some definition of ... as the mathematicians &/ Humpty-Dumpty [Alice in Wonderland / Lewis Carroll] might say) given certain assumptions / pre-conditions (on scale, frame of reference, etc.)

tiffanyg··on Taking low-dose aspirin is associated with 20% reduction in cancer deaths
This was my first thought.

It's a complicated topic, biochemically / physiologically, however. Guidelines and recommendations have changed many times in the past couple of decades. With the scale of epidemiological data collection and specific studies carried out in recent years, conclusions are still rather "mixed".

There are many reasons to think, mechanistically, that aspirin (acetylsalicylic acid) should come out "net positive" in its effects on human health. But, even some of the "prostaglandins", for example, can be important in endothelial function and health (in a positive way).

I will note that I haven't kept up with this topic much in at least 5 or so years, but, I can point to a couple of sources with some analysis / discussion that should be of use to most, I think:

https://www.cuimc.columbia.edu/news/aspirin-making-sense-cha...

https://www.uspreventiveservicestaskforce.org/uspstf/recomme...

https://jamanetwork.com/journals/jama/fullarticle/2791399

https://www.annualreviews.org/doi/10.1146/annurev-pharmtox-0...

I specifically remember concerns roughly 10+ years ago that some of the expected net benefits might, in fact, actually be net harms in the broader population - particularly for other NSAIDs (non-steroidal anti-inflammatory drugs), but, even, at some point not long thereafter, for "aspirin" as well. I may dig out that info if I get a chance to try to refresh, myself, and will comment again if / when I do.

I always think of Lewis Black's bit on this, though (while pointing out that this is the nature of science and its best to go with the best info available at any time, generally, IMO):

tiffanyg··on Report Phone Spam – Shut down robocallers and text spammers
You'd undoubtedly have to design, at least at some point, for such a system to be explicitly attacked. I'm not assuming you haven't considered that, just pointing out that this might factor into how one might approach building something from the start.

I'd suggest it will depend on goals / scale - if not many are using, probably would be ignored even if bad actors were aware of it. If it started to have real effects, there'd undoubtedly be very intentional efforts to attack it. Beyond just the sporadic script kiddiez / for the lulz set ...

Edit: sorry, "app" - to potentially use the app in some malicious way ... Not sure my comment is so useful, but, I'll leave it since it's unfortunately all too easy to end up with unintended consequences. Though, I favor fighting this garbage wholesale and support any efforts to interfere with the deluge of BS / noise with modern communications tech.

tiffanyg··on LLM Visualization
Unfortunately, this is a problem throughout our various economies, at this point.

Professionalization of management with its easy over-reliance on the simplification of the quantitative - of "metrics" - along with the scales (size) this allows and manner in which fundamental issues get obscured tends to produce these types of results. This is, of course, well known in business schools and efforts are generally made to ensure graduates are aware of some of the downsides of "the quantitative." Unsurprisingly, over time, there is a kind of "forcing" that tends to drive these systems towards the results like you describe.

It's usually the case that imposition of metrics, optimization, etc. - "mathematical methods" - is quite beneficial at first, but once systems are improved in sensible ways based on insights gained through this, less desirable behavior begins to occur. Multiple factors including basic human psychology factor into this ... which I think is getting beyond the scope of what's reasonable to include in this comment.

Yeah, that sounds like a great idea.

The US (in particular) has seen a significant decline in trust (think community, as in union, as in Federalist #10 etc.) in all manner of fundamentals of democracy and 'modernity' (tech, science, etc.) in the past several decades. And, bear in mind that there are significant differences in the way people cope with these sorts of changes and the increasing instability* quite generally for many people as well as local and regional communities.

Fire departments, since the time of Ben Franklin, have mostly, to my knowledge, doused fires with "extinguishers," not "accelerants".**

* Especially economic - not in the sense of "time for 'entitlements'", ideally, in the sense of "time to reconsider if trashing the 'New Deal' starting ~ in the 70s might have been a bad idea" ... for those not already thinking that way. Nothing better (socially) than to provide people with meaningful ways of 'acquiring capital.'

tiffanyg··on It's still easy for anyone to become you at Experian
Yes, it sure would be a shame if, I dunno, some execs at Experian were to experience some of the same issues that so many others have - due to the existence and ... 'management' of their own business ...

Why, going through such trials, ex opere operantis, might just sour a 'true believer' in the "invisible hand" on the whole novus ordo seclorum.*

More seriously, sorry you have that issue. Unfortunately, I can't think of anything useful I'm familiar with. You could look into 'inducers'. Wikipedia has a small list.

At least, though, it's good to know about the trade-offs - knowing that caffeine specifically comes at that kind of cost. Some suffer for years before determining what the actual root cause of some difficulty has been. With awareness, at least there is the possibility of volition / decision.

tiffanyg··on How to Think Computationally about AI, the Universe and Everything
figure out the computational stable state of society

Hahahaha!! That's so "psychohistory" ... it suggests such, almost 'individual'-like intention.

Also, none of it has failed. That's an absurd interpretation of where we are. The real problem is that everything we do ... all the day-to-day problems we solve, all the systems we build that fit and do a 'good job' helping us, say, in some respect, ... set us up to need even more of the same basically. As you wrote elsewhere ... increasingly complex etc.

I'd flesh out more, but, must run now.

The reality is simply that we WON'T outrun reality. There is no failure, nor is there success ... that dualistic thinking really tends to obscure rather than clarify ... by anchoring some 'conclusion' based on some specific perspective and cutting off wider views. We will follow 'the laws' of other organisms ... our own specific path, but the same basic fundamental arc ... game theoretic and in less ... abstract framings.

tiffanyg··on How to Think Computationally about AI, the Universe and Everything
The universe most certainly has a mysterious affinity with mathematics.

Is that really true?

Could it be more fair to say that mathematics has a (not so) mysterious affinity with the universe?

Specifically, where do our 'axioms' come from? Why did people spend centuries trying to prove the parallel postulate?

Partly, I'm being rhetorical, but, also, partly I'm really not. I would certainly not categorically dispute what you wrote, but I'd also not embrace it 'out-of-hand'.

... So, 'the floor is open', so-to-speak... if any have other perspectives on math-universe connection, rebuttals, etc. :)

tiffanyg··on Friend's Chandler, Matthew Perry, died at 54
Regarding the downvotes (none from me, I'll respond generally if it seems at all useful)...

First, this is, I'd say, rather off-topic ... and may seem impolite. It's along the lines of "hey, did you hear so-and-so died?" ... and someone launches into some thought that is not remotely specific to the person who died.

Second, your comment suggests you didn't even bother to 'look at the data'. 'Common sense' basically = 'alchemy', both of which are bollocks.

Now, in fairness, I'll write - among the 'letters' associated with my name, there are not only ... 'credentials', but also, everybody's favorite source of unceasing internal entertainment: attention deficit hyperspace dysplasia. You know, good ol' ADHD. So, I get it ... this may be along those lines, and even people without 'clinical-level' ADHD can have any of the relevant traits at various levels. But still, best to consider certain events like deaths - that many take very seriously - in that light, I'd suggest.

There are almost always people who experience significant sorrow and related emotions at such times. Even not knowing Mr Perry, nor being any particular fan - he had friends, family, and beyond ... all who are now hearing of his rather untimely passing.

tiffanyg··on Friend's Chandler, Matthew Perry, died at 54
Oh, I don't know about that. I mean, actually caring about other people in such a general sense suggests a sort of strong / true character in a person.

OTOH, commenting about your 'pity' in sardonic language, dripping with so much disdain and so many loaded words / phrases that what should be SUBTEXT is all anyone 'hears' - clearly indicating that all you're doing is signaling a preference and not anything like, say, empathy - well, that's about the opposite.

tiffanyg··on Two Kinds of Techno-Optimism
You said it man!*

I find the 'ethics' of everything complicated, lately. But, simple non-flashy action to just try to relieve some suffering is about as ... therapeutic as it gets - for everyone, I think.

It reminds me of that great folk tune, "Simple Gifts" (famously set by Copeland [in his style]). There's quite a bit to be said for the ideas of groups like the 'Shakers' (though strict celibacy for all does tend to be quite a headwind for perpetuation).

There is something very significant in the idea framed, for example, in the Christian Bible as "private prayer"** - the effects this has on the function and other characteristics of a person AND their community (which ideally is the world).

The mindset of as substantial a 'selflessness' as is possible for humans seems to make the world much more livable, simple, etc. (for anyone who practices towards it). It doesn't seem so common among people who become billionaires, though - this is not a dig at them at all, nor do I wish to end this comment on the subject in general. But, what's truly absurd and sad, to me, is that what everyone actually wants tends to get further away the more you cling to anything ... simply accumulate anything, including money.

Not really my style to respond / talk to myself on the internet. I mostly selfishly keep that ... perk ... of my 'carnival hall of mirrors'-esque mind to myself (unless I'm muttering more audibly to keep 'the crazies' away at the bus stop ... you know, the real ones, not like me ...).

But...

Realized I need to temper what I wrote about the 'roast' aspect of the "age check". Specifically, I think there IS a (deeper) wisdom to the setup, and a more nuanced satire of "age restrictions". What I will offer here is more the conclusion I drew years ago - drowned out temporarily by not having thought about the game in years and by the strength of the relived 'glee' at the seeming "hurling of the hammer into the 'Big Brother'" face* that I quickly realized the system could be taken to represent.

While labeled something like "age check" - the simple-minded approach, the question-based system IS more what you'd ~rationally want: a maturity check (perhaps not quite the best word, but, will do for now). I.e., what's the point in restricting access to the content in that game if someone is already at a point where they know and/or can dig up the kinds of information queried for in those questions?

I always love the example of Benjamin Franklin, the dude became an apprentice printer at 12, began writing letters that were published under a pseudonym in the guise of a middle-aged widow around the age of 15 or 16, began influencing the politics of the era in significant ways around that same age, fled his apprenticeship and lived as a fugitive for a bit when 17 ... founded a successful newspaper at 23, etc. The world was different, and some of that was more the usual than it would be today. But, at the same time, Franklin himself WAS unusual - particularly 'fast', intelligent, clever ... and, that is the point. People both on average AND as individuals do not conform to such 'simple boxes'.

Age is a practical, reasonable, and simple system - in some sense, exactly the right system. About the only reasonable system (as a parameter for sale / no sale, basically). And yet, it's also obviously rubbish. The 'question system' IS almost certainly better - more reasonable / accurate in certain ways (aside from the additional limitation / potential jest in multiple choice ... so someone who is 5 is getting in at least some of the time, which also doesn't seem unreasonable to some degree) - and also great parody of perhaps the entire concept and us more generally (e.g., the literally MOST COUNTERPRODUCTIVE thing you can do - try to hide information about a BASIC BIOLOGICAL DRIVE that has an extremely serious side).

tiffanyg··on Adam? ... is there a reason your laptop is in the fridge? (2006)
As to the fridge point, fridge vs. room temp probably wouldn't make much difference in what I glean of the scenario from a quick glance. It'd help a bit - would cool things a bit faster,* but, eh ... I wouldn't expect that to necessarily be a KEY element.

That written, temperature may still have been quite important (i.e., reboot alone wouldn't help). Particularly with a device containing something like spinning platters (as well as potentially extra heat generation associated with certain failure modes), and the additional factor of laptop heat load trade-offs, ... simply having the laptop off for some minutes might have been essential. In fact, the writer notes that transfer stopped during the first attempt to retrieve the data (after 10 minutes in fridge), hence a second round of 20 minutes was carried out after which the remaining data was retrieved.

The fact that that second pause was 20 minutes AND was carried out in a fridge may have had little to no role in success the second time. To me, that's something like a 50-50 odds event ... particularly with this kind of infrequent (for an individual, hopefully) 'high-terror' n=1 event / 'data'.** It may have primarily been the difference between having transferred other files prior to transferring that (last? not checking that detail) file vs. not.

* Newton said proportional to temperature difference, but that's a rather rough guide in general for this sort of scenario - even with just basic details missing here

** I.e., where most people aren't too interested in carrying out any kind of more detailed post-mortem ... most are much more interested in leaving the terror part behind.

Edit: OTOH, one should not discount the power of belief out-of-hand - i.e., 'externum-placebo' or something to that effect, if you please (my verbum fabulists will know). As a certain purveyor of cheap movie-branded trinkets once said in response to the soft and breathless exclamation of "I don't believe it!": "That ... is why you fail."

(Though I may be mixing up my little Gs from movies ...)

In any case, the fridge may have had more of an effect than my crudely rational analysis above suggests. {In any case}^2, this entirely unnecessary but necessary addendum will conclude with - ha ha, but, also, serious.
