    It is recent and still uncommon that private universities have a grad student union. The US also has many great public universities that have had grad student unions since forever

    Who has been projecting FTL as a realistic technology ever? FTL is not possible according to the current laws of Physics, while AGI is at least not forbidden by them.

    I read OP differently. I thought they said "we should invest in non-dystopian public safety[1] to avoid dystopian populist creating a 1984 version of public safety". [1]: I imagine…

    > And that state of the art has not moved much in the last decade This is far from true. On the experimental side, gate fidelities and physical qubit numbers have increased signifi…

    This sounds incredibly naive. Competition does not magically prevent monopolies -- once you have a dominant player they just buy or undercut the occasional competing startup.

    I am sorry, I did not mean to imply anyone else is doing something poorly. I believe glibc's (and the rest of the ecosystem of libraries that are probably more limiting) policies a…

    Wine's APIs are more stable than Linux's APIs, so it seems more plausible to me that Wine will become the first class target itself.

    non-deterministic does not mean it is not biased towards a particular type of results (helpful results)

    This is fascinating to me. I completely believe you and I will not bother you with all the common "but did you try to tell it this or that" responses, but this is such a different …

    I know that China is an authoritarian near-dictatorial country that oppresses minorities and commits cultural genocide. And I am not an American. That does not seem to be all that …

    As an aside, it is really interesting to see a computational package that, while supporting multiple GPU vendors, was first vetted on AMD, not NVidia. It is encouraging to see ROCM…

    I am happy to hear that things as not as bad as I thought, but my experience being judge/mentor for a couple of years for the high school science fair near a top university was ver…

    Reviewing a quick translation of a test to a benchmark (or another menial coding tasks) is way less soul-sucking than doing the menial coding by yourself. Boring soul-sucking tasks…

    I maintain serious code bases and I use LLM agents (and agent teams) plenty -- I just happen to review the code they write, I demand they write the code in a reviewable way, and us…

    Ask HN: A Single Board Computer for a phone alternative

    I am using my phone less and less due to it being a surveillance nightmare and due to the fact there are no small phones anymore. Now I am building a screen-less alternative for my…

    In my post I actually made a number of (seemingly unclear) claims diametrically opposite to what you surmise I claimed in my original post.

    Comment #46718841

    I find this type of posts unproductive, somewhat emotionally exhausting, and generally impolite. Most of the time open source tools are a labor of love. If the tool is not for you,…

    Usually they randomly shoot atoms at the substrate and then just search for a spot (among thousands) where it randomly has the configuration they want. Still pretty amazing.

    Shor's algorithm does not start with the qubits storing anything related to the n-bit number to be factored. The n-bit number is encoded *only* in the XOR-oracle for the multiplica…

    The initial state was the example given. It is fair to then point out the consecutive states though. A few points still hold: - I am not saying that you have to find a basis in whi…

    > When the amplitude has norm 1, there is only one nonzero amplitude. Yes, that is exactly the point. The example statevector you guys are talking about can (tautologically) be wri…

    This is completely missing the point. There is nothing fundamental to an amplitude. The amplitudes are this small because you have chosen to work in a basis in which they are small…

    Comment #46355113

    The magnitude of an "amplitude" is basis dependent. A basis is a human invention, an arbitrary choice made by the human to describe nature. The choice of basis is not fundamental. …

    Isn't 250 square meters already pretty small for a company of their size? That is a small McMansion, and in Serbia the rent is probably 1k$ per month.
