Locklin on science

I’m a scientist, I don’t believe in anything

Posted in five minute university, fraud by Scott Locklin on June 25, 2024

In my early lab career I needed to fabricate this square yard plate of inch thick 304 steel into something useful by drilling lots of holes in it.  It was a bit beyond my skill: one of the holes was 2 feet in diameter, and 304 is bloody awful. After blowing up too many $20 mill cutters, we called in a real machinist. This was early 90s, so Pitt still had some cool mustache dudes who know how to do useful things like this. I don’t remember what his name was, or even how he accomplished all the big holes (boring bar with the big one), but I do remember he used to fuck with me. Just like in the good old days when I was an auto mechanic. His way of fucking with me was to tell me things which were obviously not true about setup of machine tools, flying saucers, women, eating hot dogs: whatever came to mind. Nothing dangerous; just the kind of thing guaranteed to blow up a milling cutter or getting mustard on my nose, or having a waitress slap me upside the head or what not.

Working class people do stuff like this all the time; little pranks -it breaks up the day. But the cool thing about this guy is he told me that most over educated people have this cognitive flaw; we’re credulous. We believe anything we’re told if it seems plausible, especially if we’re unsure of ourselves, which we mostly are. Nerds are learning machines; that’s why we get paid. Nerds don’t like thinking about stuff; they mostly shove things in their brains like fat people stuff themselves with doughnuts and pizza. Machinists are a bunch of working class dudes who don’t believe anything from this constant ribbing by their colleagues, and the fact that some of their colleagues are actual retards (note to academic/tech bros,  some of your colleagues are also actual retards: many such cases). They think and ask questions before they believe. “OK if I start with the cutter there, what will happen.” This is the essence of science and engineering.  Believing the guy telling you to put the cutter there just because he knows more shit than you is just setting you up for  a minor prank on  you.

The implications of this are immense; most nerds are insecure even within their intellectual realms. Tell them something technical, like the two years of “muh covid” baloney and they spin up their intellectual powers trying to understand the information put in front of them. No critical thinking is employed, they’re too busy trying to master the difficult material put in front of them, just like they did when they were a larval interlectual in skrewl.  It’s the same with any old marketing baloney. Many people believe the M2 architecture is faster than, say, my 2011 vintage Sandybridge stinkpad. Apple spent all that money on it, after all, it must have been a genius move for consumers who want computational horsepower, right? The nerd happily spreads his intellectual buttcheeks and spends all this time reading the wonders of the M2 as if it were actual information rather than marketing baloney (you know, disinformation). And of course every smart person knows about Moore’s law, so obviously it must be exponentially 13 years better than an I7 of 2011 vintage. M2 might be faster if you’re doing video codec crap, but it certainly isn’t for every day tasks. You know, like generic matrix multiply. That will make M2 weenies real mad; they are the smarties and Locklin is the dumbass right?

I blame Kebab if M2 results are actually faster here

I mean, feel free to check it yourself. There’s lots of anti-knowledge like this out there; propaganda or in the apparatchik parlance disinformation masquerading as information. People think Apple invested in this architecture for performance reasons because the propaganda tells them what a triumph it is. The reality is probably something like it’s easier for their developers to build to one architecture; ipotato and ipotatobook, and Apple gets to keep more value by not dealing with Intel, even though Intel’s chips are obviously better.

I often find myself completely alone in denouncing the most obvious and egregious impostures; nanotech, openAI, FTX, noodle theory, autonomous vehicles, quantum computing BS. When I do this, nerds are furiously googling up wikipedia articles trying to refute me because their self-conception involves being the smarty pants know it all who was a good little boy and studied hard qubit to make  teacher happy. When the market mean reverts and the line converges to reality rather than someone’s marketing to dorks, these nerds dutifully forget how wrong they were and move on to the next thing they’re going to be wrong about.

Putting aside the specific cases where I was right and all the sputtering  “well actchooally” nerds reading wikipedia articles were wrong. This dynamic of nerds falling for marketing hype and various crazes has dominated the directions of the last 60 years of research and engineering development. During the first decade of that timespan we got moon landings and integrated circuits, but compared to the period between 1900 (pre Wright brothers) and 1960 (post Sputnik), that ain’t shit. Worse; all the real progress stopped after the first decade: 1970 to present has been absolute shit. It has been shit in part because of this sort of credulity. Credulity begets crazes and makes such people the pawns of marketers who get free amplification from NPC nerds doing their science and technology ghost dance. We don’t live in a golden age of technology: we live in the age of propaganda and marketing. Virtually all visible technological development of the last 20 years is for the dissemination of propaganda and surveillance.

If a field has marketing associated with it: drug manufacture, tech, auto manufacture -the things you think you know are probably bullshit. We’ve established that the humble and relatively unimportant subject of machine learning contains  pervasive and amateurish marketing bullshit. You can probably find interesting things going on in subjects like Geology, petrochemicals or Archaeology with shields mostly down. For those who have to work in marketing infested areas, you need to be extremely bloody minded. Ask yourself how you could know if the claims are true, independent of someone making the claim. You absolutely must not listen to any experts without a complete “qui bono” analysis: you need to think through how the information in question got in front of your nose. There are no more “scientific americans” to do the vetting for you, and everything now published there and in other such legacy places is probably a lie. “Experts” are almost universally frauds.

The upside to all this is history has restarted and everything is up for grabs. The mass of bugmen LARPing as scientists, government welfare queens, bureaucrats, snitches, nerds and bums are weak: they’ve allied themselves with the other floundering Western “authorities” who are all-in on censorship: the precise opposite of the scientific process. Times like this are when things start to move and change. It’s not going to happen in existing large institutions, but it is going to happen.

    When I was in the service we sent a guy whose nickname was “Sugar”, because he was so sweet, to go out and find a left-handed pulse stretcher for the o-scope.

    He came back after a long frustrating time with an Allen wrench, only to have the NCOIC berate him for wasting his *&&^%$# time with a right-handed pulse stretcher.

      Anyone who was in the Navy is familiar with the mail buoy, sea bat and BT punch. My favorite story was a seaman who told to complete a requisition form for fallopian tubes. He got signatures from his leading petty officer, chief petty officer, division officer and department head. The XO finally put the kibosh on it.

    I guarantee an M2 can multiply matrices faster than your Sandy Bridge laptop from 2011. See here for example, where an M1 is nearly twice as fast as a 12-core Sandy Bridge machine, without using the GPUhttps://web.eece.maine.edu/~vweaver/group/machines.htmlYour result may have something to do with J. The thread you link to seems to be J people trying to figure out how to best run J on Apple chips.

    • Scott Locklin said, on June 26, 2024 at 6:57 am

      You have absolutely embodied what I’m talking about in almost every detail in this post; thanks for the real time demonstration.

      • clumma said, on June 26, 2024 at 9:32 pm

        Sure. I did matrix multiplication benchmarks for Apple back in Nehalem days, but what do I know?

        I’m a fan of your blog. Been reading for years. You get many details wrong (as here), but your core point is directionally correct and your prose is entertaining. Keep going.

        • Scott Locklin said, on June 26, 2024 at 9:46 pm

          You didn’t pay attention to anything that was said. The benchmark is single threaded and naive as is described in the first line of the helpful link I put in there. Did you run it? Did it run faster than my thinkpad on your M2 machine? Did you notice the I9 single thread results were preposterously faster than the M2 results? Those results represent what most code will do.

          Showing me some dumb benchmark based on two different versions of variously timed BLAS, by contrast, is fucking meaningless reddit baloney. If you did this for Apple, you produced marketing propaganda for them: you didn’t test anything.

          • clumma said, on June 26, 2024 at 11:32 pm

            Not clear what anyone in that thread is doing. Most seem to acknowledge that the M2 results must be due to bad optimization, as I said. The i9 mentioned is a 10-core Comet Lake part that runs up to 5.2 GHz and the author claims to be using multiple threads.

            CPUs and compilers aren’t magic. A compiler can only degrade performance by compiling things stupidly. And once memory bottlenecks are avoided (strictly worse for your 2011 machine), a CPU core is exactly as fast as its instructions/clock * clock speed, modulo any coprocessors (M-series chips have three coprocessors useful for matrix multiplication).

            It’s possible to claim many things have gotten worse. Like our ability to launch Minuteman missiles. Single-core performance on microbenchmarks isn’t one of them.

            The benchmarking I did at Apple was for internal use and never publicized.

            • Scott Locklin said, on June 27, 2024 at 8:32 am

              The Benchmark is the naive single threaded J mmul, not your imaginary “if I was running X version of BLAS” or “but I didn’t use muh special accellerator hardware” marketing exercise. Almost all ordinary code will run like this. That’s what makes it a useful exercise. The multithreaded version J is working on is also useful, but irrelevant, which is why it ain’t in the screencap.

              FYI, my stinkpad was 2x faster than a 2017 era powerbook as well, so things do indeed get worse.

              I notice that, despite my carefully writing this funny article illustrating this cognitive trap for tech people which has destroyed progress for half a century, and upbrading you for being a cement head and doing exactly what I’m grousing about, you still haven’t run it on your shitty M2 machine. What are you afraid of?

                Numbers do not lie. The M2 isn’t much better than the Sandy Bridge Xeon, albeit that was a 110W TDP server class CPU.

                With GPU and “video codec stuff”, modern hardware reigns supreme.

                  All he wanted you to do was not to believe that is said, but test and verify.

                  Anybody that wants to seriously argue about cpu architecture performance should have zero issue running a simple J language benchmark to do it.

                  From the image:

                  “I blame Kebab if M2 results are actually faster here”

                  He provided all the necessary information there to refute it. The language and the version, the OS, etc. It is software that is free to download. Just get the zip and drop it in your home directory.

                  I mean I am a moron and never used J before, but I am pretty sure that with a half hour or so of searches I could figure out how to do a matrix multiply with it and challenge him.

                  Hell I doubt he would object to you running benchmarks in a completely different language.. like javascript, C, or python. It wouldn’t be as cool, but at least it would be something.

                  The whole point is that modern “tech wennies” won’t even bother to put in the smallest amount of thought or bother to learn anything new and will instead get personally offended, google something stupid and throw links at him as if it was a slam dunk.

                  • nate-m said, on June 28, 2024 at 4:18 pm

                    Not saying what you are saying is wrong.

                    Just that the discussion itself is silly.

                • clumma said, on June 28, 2024 at 7:13 pm

                  According to that, the M2’s fp perf is 50% higher and “single core” perf is 150% higher. And that’s against a Xeon. Locklin says his Sandy Bridge thinkpad is faster. But it seems he didn’t benchmark the M2, and only refers to someone else who claims to have done so. And that other person’s J code is conceivably running in emulation, or who knows.

                  Locklin used all this to construct an argument about how society is crumbling and how people who use reddit masturbate too much. Then he hurled insults at me when I pointed out he was full of shit.

                  You’re right, it is silly.

                  • nate-m said, on June 28, 2024 at 8:09 pm

                    But it seems he didn’t benchmark the M2 

                    Yes. I think that is the point.

                    It should be extremely simple with somebody who understands cpu architecture and knows better who happens owns a M2 mac or similar device to easily blow his entire ‘Apple uses ARM because it is cheaper for them, not because it is faster and they fooled people with slick marketing’ argument out of the water with a simple demonstration.

                    It would be a really easy slam-dunk thing to do.

                    I don’t own a Mac and have no interest in them whatsoever. So I wouldn’t be that guy.

                    I own multiple ARM devices that I could run the benchmark on, but those are designed for low cost and low power usage… not to be the next laptop-shaped super computer. So it would be pointless.

                  • Scott Locklin said, on June 28, 2024 at 10:25 pm

                    I didn’t say any such thing as “society is crumbling.” I did mention that you are a numskull with poor english language comprehension who can’t run a benchmark. These are rather different statements; even a chowderhead such as yourself should be able to understand the difference. Go run the benchmark, or, like, get lost. Stop googling “facts” and use the protrubence on the end of your neck for something useful. The guy who verified the J-list results for me never worked for Apple, and in fact is not any kind of engineer or programmer: you should be able to manage with your giant water cooled brain. Should take all of 40 seconds.

                    FWIIW I didn’t think the M2 would be slower than my computard either, but it appears that it is.

    I’ve tried to introduce a few friends to the idea that physics, or technology in general has stalled in the last 50 years and they don’t want to contemplate the idea. It doesn’t help that I’m not a physicist in the explanation but they point to their own fields, largely medicine, which are significantly downstream of physics and regardless of hype will realise what physics makes possible later. Not that majority consensus should matter but I think many people don’t want to think about “the science” investigating the wrong ideas due to path dependence in funding or that we aren’t as brilliant as we were in the past.

        • chiral3 said, on June 26, 2024 at 6:52 pm

          Those butterballs need some Lizzo if they can’t afford ozempic. But they’re healthy, and we need to be body positive, esp since they probably have mental illness. But we should also trust the science. Experts say they are healthy (as is the insurance cash streams from medical treatments).

          I recently ran into some people I hadn’t seen in a while at a party. She’s cute, and I noticed she had crazy eyes, which was new. He’s cool, but has a dark side that never bothered me. They were sticks. Their transformation wasn’t keto and HIIT, it was something else. And he developed a weird full-body tick that he couldn’t control. They looked like an American Gothic version of Edvard Munch’s the Scream but with trendier clothing. After talking for a while she switched gears and her eyes got wide and she started to slip into sell mode and tried to close me on poison frog shit. She has a regular job but now she’s a shaman, according to her and some other more senior white chick shaman from Brooklyn. I dig the whole shaman thing. I have many books in my library by anthros and ethnos documenting stuff from Peru to Mexico over hundreds of years. Usually DMT centric stuff, lotsa ritual, and the assault sorcery stuff, the kanaima, which reads stranger than fiction. But what she wanted to do was change me forever by burning holes in my body, scraping the poison glands of some Amazonian devil monkey frog she spatchcocks between two stick, and rubbing the poison in the wounds. This is all after 24 hours of leach therapy. Her euphoria was periodically interrupted by the husband’s body spasms, which may have been a coincidence, but dollars to donuts it’s because she’s pumping him full of frog poison. But at least they weren’t fat. Thank God they weren’t fat.

              Phyllomedusa, leaf frog, not even 5-meo-dmt stuff. Funny thing is various DMT compounds are in tons of different plants, not always 5-meo, but dmt more generally. Researchers have figured out that the proportion of maoi plants that the south american brews far exceed an amount required to get the good stuff past hepatic metabolism. But that excess is also what presumably induces all the vomiting, which in itself probably helps mitigate other negative effects (like not being able to process tyramine, which is probably rife in open fire cooked meats that are staples in their diets). So with a little chemistry these hip neoshamans don’t have to hop on planes and import poison toads, they could forage in central park. But that’s not as cool.

              • Scott Locklin said, on June 26, 2024 at 8:24 pm

      Watch movies from various times over the past 30 years, particularly since 2000. Lifetime movies are especially good for this as they depict “normal” people in normal lives. The only way you can tell when the movie was made is by the kind of cell phones depicted in the movie, either a flip phone or a smart phone. Everything else, the cars, the houses, everything, looks the same. This is over a 25 year period. That alone should tell everyone that real physics based technology has slowed.

    AAPL silly con smelled funny back in 2020, when Monero CPU benchmark (slightly more real-life number cruncher than others) showed nothing special, in terms of (GH/s)/W, when compared to same year AMD CPUs.

    Low-level cryptomining guys are skilled in terms of squeezing every bit of SIMD and multicore optimizations, but not so skilled when it comes to taking AAPL money and licking their boots, like subsidized geeks from Geekbench did by polishing their synthetic benchmark to shine on one particular platform.

    Later I compared my wife’s M1 Pro Macbook Pro with my Ryzen 9 5900HX laptop in Linux kernel compilation benchmark inside Docker. My laptop was ~30% faster.

    I’ve echoed something similar talking to, I suppose, millennial college kids. Probably the only generation apart from late GenX that spans generational groups that embody conjugate personality traits. The former group was incredulous; maybe not cynical, but certainly skeptical in one extreme, and largely prodding and inquisitive more generally. Maybe a little doveryay, no proveryay. In the latter group it almost creates a sense of psychological distress and physical unease to question consensus and groupthink, which seems to be emergent phenomena fueled by marketing, unless they are demolishing their cultural inheritance or various shibboleths. It’s career limiting – academic, professional – to kick the tires, especially if that kicking encroaches on the hyperreality. It seems much of this is style – it’s not socially acceptable tell someone they are being an idiot, at least outside of life or death situations. There’s no point in fighting a tide that is ebbing at a dozen knots faster than people can swim when the manufactured reality doesn’t encroach on basic human needs nestled on the lowest level of Maslov. Not sure I am as optimistic as you that “…it will happen” without things encroaching on basic human needs. Now, one can argue, that it already is, given education, mortality, competition,…, but that’s where the hyperreality comes in; there’s a welfare system of PMC and bureaucrats to leach off the masses.

    This is the age of hype, exaggeration, fibs, etc. Marketing has become the dominant mode of communication. You pinned it perfectly Scott. I think there is probably a prevarication density function that one could calculate for any society. There is most likely a critical level above which planes fall from the sky and nuclear reactors melt down. Once you exit from the more technical / scientific realms into politics, society, etc., the function goes asymptotically to the ‘total fabrication’ level.

      Found a chart that says that for 2020 the budget for online advertising is north of 220 billion dollars. This year might break 300 billion.

      That is a lot of money spent on trying to manipulate perceptions and getting people to believe what you want them to regardless of whether or not it is real. They have become experts at it.

      I think Bill Hicks was right. If anybody wants to figure out the single most important source of evil in our society then advertising should be at the top of the list.
