  • Siblings yes, just about everyone else no. We have no interests, morals, or politics in common.

  • Okay then yeah we should definitely do that. I already have told the about three people I actually know about Lemmy.

  • Nope, sorry. I am not socially competent enough to know how to moderate a community of any size. But it sounds like a cool idea, so I hope you find good mods soon.

  • Me and a lot of other people don't respond positively to advertising. Actually, if I see an advertisement to buy something, or someone was bought to sponsor a company, I'm a lot less likely to buy the product.

    Self-promo and just promoting stuff you personally like is different IMO. In that case, I am very much interested in what ordinary people want me to see. Hence why I'm subscribed to communities like !buyitforlife@slrpnk.net because these are humans with real opinions who aren't just trying to make money off me.

    But also...I block Internet ads, and IMO for your security everyone should be blocking Internet ads, so I'm not sure how taking out Internet ads in particular for Lemmy would be helpful.

  • It's really nothing interesting, but here's some stuff that I think might make Lemmy cooler, but also don't take this too seriously since I'm not in a mindset where I'm ready to code this stuff myself:

    • More characters in profile bio. Too short!
    • Direct democratic election of moderators for communities as a built-in option. For example, mods can be voted in or out somehow by community action.
    • In general, multiple possible built-in technical structures to support multiple social structures.
    • LaTeX support because I'm a math nerd.

    Again, none of these are silver bullets, and IMO it's more important to get the core features right first.

  • Nononono you're not advertising of course, but the comment I replied to suggested advertising Lemmy.world.

  • We probably don't want to do that. Lemmy.world already has too large a share of the Threadiverse's user base. Centralizing around one instance is how we got the Reddit API fiasco last year and... Reddit overall.

    Also... please no more friggin advertising lol.

  • Try to make my community or technical contribution as cool and useful as possible. IMO the utility of Lemmy is really the ability to connect with other people all around the world based on our interests. The money is only important insofar as the devs and admins need money to eat.

    Reddit is a business, one of whose least important goals seems to be maintaining a safe online space for humans to chat. Lemmy isn't about the money; it's about the people.

    I have a few ideas for things that might be cool, but none of them are "silver bullets" that will make everyone immediately come over to Lemmy, and frankly they're not special. IMO we need to slowly, "organically" create communities and technical infrastructure that people want to come to.

  • Quantum Physics Postdoc here.

    Can we trade?

    Great write-up btw.

  • Not at all. In a classical computer, the memory is based on bits of information which can either[1] in state 0 or state 1, and (assuming everything has been designed correctly) won't exist in any other state than the allowed ones. Most classical computers work with binary.

    In quantum computing, the memory is based on qubits, which are two-level quantum systems. A qubit can take any linear combination of quantum states |0⟩ and |1⟩. In quantum systems, linear combinations such as Ψ = α|0⟩ + β|1⟩ can use complex coefficients (α and β). Since α = |α|e^jθ is valid for any complex number, this indicates that quantum computing allows bits to have a phase with respect to each other. Geometrically, each bit of memory can "live" anywhere on the Bloch sphere, with |0⟩ at the "south pole" and |1⟩ at the "north pole".

    Quantum computing requires a whole new set of gates, and there's issues with coherence that I frankly don't 100% understand yet. And qubits are a whole lot harder to make than classical bits. But if we can find a way to make qubits available to everyone like classical bits are, then we'll be able to get a lot more computing power.

    The hardware works due to a quantum mechanical effect, but it is not "quantum" hardware because it doesn't implement a two-bit quantum system.

    [1] Classical computers can be designed with N-ary digit memory (for example, trinary can take states 0, 1, and 2), but binary is easier to design for.

  • Ask and you shall receive:

  • EE major here. All the equations in the third panel are classical electrodynamics. To explain the semiconductors needed to make the switches to make the gates in the second picture, you really need quantum mechanics. You can get away with "fudged" classical mechanics for approximate calculations, but diodes and transistors are bona fide quantum mechanical devices.

    But it's also magic lol.

  • Wah-wah pedals are resonant filters with an adjustable cut off. Rock and metal guitarists have been using them in solos to create that expressive "crying guitar" sound. Classic example is the solo in Sweet Child O'Mine by Guns N' Roses.

  • The result seems to me to be more like Reverb in my perception/use.

    You're on to something: reverbs often intentionally create resonances. Reverbs can be simulated with a filter (although commercial reverb plugins and hardware typically sprinkle in some non-linear goodness).

    What does the absence and abundance of resonance reify as observably?

    In audio systems, it sounds like you added ringing to the signal. If it's too much ringing, eventually the ringing will dominate over your signal and you'll basically get a sine wave at the resonant frequency.

    Below is a response of a filter with a resonance:

    You'd have to show me a diagram or plugin with the control labeled "R" to be sure, but I believe that with respect to the above diagram, R is equivalent to ζ (zeta). However, some plugins use Q = 1/(2ζ) as the parameter for the user to change, in which case the intuition is practically "backwards".

    When ζ is about 1, the system described by the graph basically doesn't ring. As ζ goes to 0, the resonant frequency and its neighbors start to get boosted, giving the characteristic "ringing" sound. If ζ = 0 (or practically is close enough), you get an oscillator, i.e. you generate a sine wave with the resonant frequency.

    What does R refer to or what is it a spectrum from->to?

    The spectrum of the filter is actually the curve above, along with its phase curve, which gives you the output of the resonant filter given any input. ζ and Q are different ways of specifying the strength of the resonance.

    Note that I used a filter with just a resonance for simplicity, but any filter can have a resonance, including low-pass filters, in which case ζ is often used as a parameter in the math. You can logically think of a resonant low pass filter as a "non-resonant" low pass in cascade with a resonant peak (order doesn't matter) at the same frequency you set the low pass to, even though they're not designed that way.

  • Nah it's cease, e.g. "The IRS made my money cease to be my money."

  • Russian bots aren't all that bad

    Yes, in two senses:

    1. I don't lose sleep at night knowing that these bots exist (or those of any other government). They shouldn't exist for the simple reason that public institutions shouldn't be in the business of deceiving people, but unfortunately, deceiving the public is a bunch of what the State actually fucking does "for" "us". I especially don't think the Russian government cares to run bots/trolls on our little corner of the internet when bigger targets exist.
    2. Vacuously, I don't disagree with literally everything that the Russian bots say because they can be found saying just about anything.

    I cannot stress enough that I do NOT approve of state-sponsored botting or trolling of public spaces in general. However, when you see Pro-Russian or Pro-whatever opinions on the Internet, you are probably reading the words of a "useful idiot" or non-State troll.

    This reality is a lot scarier than if the opinions were all just from some Russian troll farm, because now we have to interrogate the reality that these people have different and complex reasons for why they ended up with those opinions. It means that the task of persuasion is a lot more complicated than just shielding people from bots and trolls.

  • if you find yourself on the same side as Russian bots and don't find it so disturbing that you immediately change your position

    As mentioned by another commenter, the actual strategy of the real Russian government is to sow division by advocating a bunch of positions, so a particular position being presented by Russian trolls absolutely does not warrant immediately changing my position. Your position is not special in that regard.

    But more generally, I'm not going to change my position on anything solely because someone awful agrees with it.

    And even more generally, I don't care about unifying people under the political agenda of any existing government or political party. I want to see people unified about organizing themselves. To that end, letting one of the existing political parties, including yours, dictate our political will to us goes against the goal of people organizing themselves.

    you can't claim any high moral ground use that to lecture other people.

    I do not claim nor need the moral high ground to present my opinions. Same goes for everyone else.
