Laplace transform is for exponentials, fourier is for the sine function (ie a complex exponential). So they do the same thing just with different weight functions.

All of this is just linear algebra, with different linear transforms. A fourier transform is a linear transform that transforms point space basis to harmonic oscillation basis.
We just need a formula that finds a sequence of digits in pi instead of a single one.

IMO because you can configure the BMC to use it's own dedicated NIC and network.

That network should have no routing to the Internet and no production traffic,
just BMC management.

When Intel ME shares the NIC used for the OS traffic - that is far harder to secure.

Yes, we are too much focused on the reverse problem.

We know exactly how much time we need to compute the nth digit of pi. But how much time do we need to find a specific string of digits? Seems like a more interesting question.
Sines and cosines are the best choice here because they're the "elementary periodic function" for a given frequency: the sum of two (possibly scaled and shifted) sinusoids at some frequency is also a (scaled and shifted) sinusoid at the same frequency. For other shapes of periodic function it's not true: for example, if you sum two triangle waves of the same frequency but offset from each other, you'll get a shape that's more complex than a triangle wave. Same for two square waves etc. So the most natural way to decompose a signal is into a sum of sinusoids rather than triangles or squares etc.

I've writing and freely shared a lot of OSS code and I plan to continue doing that. All MIT licensed.

But I keep thinking that this is a limitation of MIT. It's written with the purest of good intentions but without any way to prevent bad actors from exploiting that.

I wonder if there's a better kind of license that provides a close level of freedom but would prevent some of the most obvious exploitations (e.g. packaging and selling the code, or reposting on a site with advertising)?

There's copyleft licensing like LGPL but perhaps that goes too far in the other direction and besides, it seems to be very unpopular amongst web developers so I'm afraid if I release any LGPL code it won't get used much or attract contributors.

Is there a happy medium between these?

It's worth a read, but perhaps it found me at the right time in my life.

No, you can do a Chi-squared to test whether the distribution is significantly different from theory in any way.
That's a pretty good guess: lots of BMCs have fan control, and turning it off should make all fans stay at max power.

In a datacenter the odds of anyone noticing that the fans are always on high is practically nil, unless you are specifically monitoring fan RPM. Most folks don't bother, as what you are actually interested in is temperature.
Or just say that the (complex) amplitude at a particular frequency is the dot product of the signal and a (complex) sinusoid of that frequency.

Then you’ll immediately understand how the Fourier transform can be just a change of basis (a matrix multiplication in the discrete case).
I think the best semi-intuitive, non rigorous explanation I've seen of the Fourier transform is still one that first explained signal correlation in the time domain and then described the transform as basically performing correlation on the signal for all the possible sines at different frequencies. Essentially you're just testing for the presence of individual sine waves (of different frequencies) within the signal.

Unfortunately I can't remember where I saw this explanation. It might've been in the Scientist's and Engineers Guide to DSP book.
There’s nothing unpopular about this. In fact this is the most popular opinion on HN.

> * [Supermicro BMC] Various IPMI commands just lie about successful execution. For example, setting the asset tag via the FRU succeeds, but has no effect. Those commands require toggling a write lock bit via an OEM command, which I only found by reverse engineering.

we have Supermicro server with serial flashed to be something like 12345678 which means it probably doesn't work reliably on their production line either lmao
I should say, I will run binaries on VMs and feel very little threat from doing so. The "with no exceptions" referred to the main host OS. I should have been more clear about that.

To answer your questions, oh hell no; definitely I do not audit source code myself. Though I have rarely. I do it this way, and it is different enough for me, because someone could audit the source in theory. If someone did audit and found a security problem, then I could check to see if my source was also compromised. If I install binaries, then I might not ever be able to know if my binary was compromised. Maybe someday if reproducible builds are guaranteed to be bit-perfect, then I would use binaries from reputable sources, but that would only happen in the case where third parties are compiling from source and affirming the reproduction. In that case, why not just compile it myself?

Developers who publish compromised source are going to get burned. Developers who publish compromised binaries are going to say, "omg we must have been compromised by someone else." Obviously it is possible for third-parties to compromise source, but I'll go with what I see as the lesser threat.

If the cost of compiling was high, then that might make a difference. For me, the cost is negligible, which makes it a no-brainer for me.
I've wondered about the same thing of generating a permutation with a minimum number of samples. I'm not sure how Gray codes helps you here, and the multiplication sounds wrong since many outputs aren't reachable from any input.

I may have found the answer, and I've seen this before (it happened to me once). It's when a different spam site copies your content wholesale, and a search engine decides they're the "original" site, and you're the spammy copycat.

Because if you put the headlines (in quotes) from two of his recent articles into Bring, e.g. either "Megan Smith explaining the General Magic prototyping process" or "Denialists, Alarmists, and Doomists", both point as their first result to a URL starting with "https://www.scien.cx" which seems to be the spam site with a copy of each article. (The URL isn't loading right now, however, when I try to visit.)

How to fix it really depends on what techniques they're using to mirror your site, of which there are many.

Example search and resulting URL:

https://www.bing.com/search?q=%22Megan+Smith+explaining+the+...

https://www.scien.cx/2022/12/25/megan-smith-explaining-the-g...

He may have "stolen" the beginnings of Tesla, but he still ran it for a long time (like he runs twitter now). Somehow he didn't ruin it and instead built a lot of cars and a few big factories. Disregarding all the marketing fluff, I still find the result to be pretty impressive.

Not going to disagree that his behavior at twitter is erratic at best.
He had been writing unmaintainable code for years and finally he experienced what it was like for everyone else. That's hardly a mistake.
I think it's easier to press than anything more conventional (and also super-easy to remember). This fast and smart jumping around function is one of the biggest things I miss when I use Emacs — and the shortcut is an important part of the experience.

> I just press it occasionally.

Wouldn't that be a big problem only if it was something more destructive than a search popup?

P.S. But I may have a weird perspective on shortcuts: the one I have sweared about pressing accidentally more than once is Ctrl-Alt-Backspace. For the unfamiliar: it's an emergency way to kill the X server (=> the entire graphical user session), nowadays usually disabled by default.
The key insight for me on this topic also came from 3Blue1Brown, but in a different video: it’s that e^x is NOT best thought of as repeated multiplication, but instead as the function exp(x) = 1 + x + x^2/2 + X^3/6 + x^4/24 + …

After being relieved of the burden of that misconception, I was finally able to understand the role of complex numbers in the Fourier Transform.

Because I don’t see much explanation in the comments, I’m going to give my layman understanding of how this works.

When an egg and a sperm cell come together to form a new cell, you have two aged cells coming together and somehow from that you get a cell with age zero. In 2006 a Japanese scientist named shinya yamanaka discovered that this age reset actually happens a few days after fertilization, in a process where the epigenome gets reset to baseline by a chemical signal of 4 different factors. Express those factors, and any cell in your body becomes a pluripotent stem cell. For this he won the Nobel prize.

What this new research is attempting to do is to do a soft reset of the epigenome- to reset cells to a youthful state without completely reverting them to stem cells. They are also attempting to show that you can cause a mouse to age by inducing breaks in non-coding parts of dna, which indirectly causes degradation of the epigenome. They claim that it is epigenetic drift, not genetic alterations, that causes aging.

There’s nothing about this research that seems peculiar to mice. I’m not a biologist but to me, it passes the smell test of at least being plausible- although I think that correctly resetting the epigenome of every different type of cell in the body is going to be a very, very complicated task.
Trump-esque? what words has trump even done that for? Changing the meaning of words to fit what you want has been happening long before the printing press even was invented by people in power, vying for power, reporting on things they have a biased interest in or just wanting a quick win on an argument. Not everything needs to be a trump analogy.
> best semi-intuitive, non rigorous explanation [...] signal correlation in the time domain [...] basically performing correlation on the signal for all the possible sines at different frequencies

That's only going to make sense for someone who understands your jargon usage of "correlate", and who groks that integrals of sine curves are orthogonal under addition. That's precisely the hard part the linked explanation is trying to explain.

If you've already gotten that far then the DFT is just calculator math.
Redesigns will always be controversial, especially with tech-people. Personally, I quite enjoy the redesign.
Nothing will change there. There are already much more efficient methods of calculating π. What this lets you do is jump straight to the nth digit without calculating all the ones before it.

The site is pretty. However, I do not get the same message from this site as I do from the book it’s based on.

When you get farther into the site and it’s telling you what you should be doing… no thanks. That comes off as prescriptive and condescending to me. I did not get that from the book.

I found the book to be more of a thoughtful reflection on “the productivity trap”. Also the pace at which the book introduces and moves past existential dread is much smoother.
In that spirit, my pet "a monad is a monoid in the category of endofunctors, duh"-style one-line explanation of the Fourier transform is that it's just the decomposition in the common (Hilbert) eigenbasis for all translation operators. It makes it surprisingly clear (to some) why it is a both natural and important construction.
A reliable bug! :-)
The idea is just a closed form solution that gets you from a number in 1...nPermutations to a single specific permutation. I was using Gray codes as an example of a sequence that exhausts all permutations with a closed form that gets you to a specific point in the sequence.

Might not work - as I say I never actually got around to implementing it.

Some of these are due to philosophical insights that IMO (and many others’) psychedelics can confer. In particular they’re known for generating a sense of oneness and for revealing the deeply subjective nature of reality[0]. Buddhism has been exploring these ideas in depth for millennia, so I think psychedelic usage can push people in that direction pretty easily.

Dreamcatchers — rather indigenous culture broadly, at least in the US — also has a developed philosophy of oneness with nature. Again, when you see the insights psychedelics have to confer, it makes sense to go find the people who’ve been talking about those insights for millennia. Western thought is just an entirely different train. It’s all extremely valuable IMO but we have artifacts of western philosophies all around us every day. None of these are intended to remind us of The Big Ideas that one is likely to come across via psychedelics.

Colorful shirts: This is because you just appreciate certain patterns/colors more after seeing them on psychedelics. No clue how to describe this lasting impression but it is VERY real.

Pyramids/crystals: no clue but entirely possible they just fall into the same category as shirts for that individual (alongside things like kaleidoscopes).

[0] Note this is NOT some new age woo woo about quantum whatever. It’s the factual observation (made more obvious via meditation or psychedelics) that 100% of our experience of the world occurs via the “interpretation machine” that lives mostly inside our skull. Not one of us is making direct contact with “reality” as it exists beneath human interpretation.
I think it was basically this dude building an LLVM compiler for Porth, which made Porth's creator (Tsoding Daily) uncomfortable because he felt like he was on a race to see who made his own unfinished language better. He says individuals with an "s", so I'm not sure who else he might be talking about, but I remember this LLVM person being the big shocking reason why he initially closed the source code.

As far as I remember, the LLVM dude apologized in a public comment on the same video where Tsoding complained about this, claiming he was closing the LLVM repo and explaining it was just a toy project he made to understand LLVM better that got some attention.

“Haters” might be too strong a word, but of ugh-ers there are plenty, and humanities education does not seem to help—neither with the ugh-ing, nor with the social approval of said ugh-ing. And that is substantially harmful up to and including societal scales[1].

Not that the ugh-ers are entirely at fault! In society where nobody actually teaches anything deserving to be called “maths”[2], certainly nothing that would give any clue as to why people would actually want to do this thing[3], there’s little they could do to do better. Except maybe, as adults, wonder why there is this strange cluster of people who appreciate this apparently repulsive thing and investigate the reason for themselves.

(Not that this appreciation is universal even among experimental physicists, for example.)
