  • it's a simple question

  • Yes, you are mostly correct. In some sense, it is more a cultural thing. If your Arch breaks, the expectations for your ability to deal with it yourself are a bit higher. There are good instructions and people willing to help, but the latter (both inside and outside of Arch community, I think) may tell you that you shouldn't be using Arch if you don't meet their expectations.

    Anyway, another aspect of it is the fact that with my system, I am a bit of a tinkerer.

  • You know, the kind that insists on using Arch, despite being slightly (or more) below the skill level one should have before using it.

  • Searching for a smooth function that goes from flat zero to exponential growth

    Jump

  • I did some numerical differentiation, with ten thousand points between 0 and 10. Negative values appeared in the third derivative. The attached figure zooms into them. While I think those sudden spikes may very well be numerical artifacts caused by float rounding errors or something like that, there is a clear negative slope around them, further confirmed in the fourth derivative. So, this function is not what I hoped it to be.

  • Could you approximate derivatives by finite differences?

    Yes. I will try that.

    Could you write your own code implementing the the derivatives?

    No, I don't think I could.

  • You can think of the convolution as a process to smooth the function g by making its values at points around each t affect that at t. So, tau is the distance between t and another point, and Psi(tau) tells how much the other point contributes to the smoothing at point t. In a more decent situation, the integral in (7) would have been properly solved and tau would have disappeared, never to bother us again.

  • Hi Larry!

  • When I read the title, I thought "Surely this Larry cannot be more cited than the famous F. D. C. Willard". But then I read the article and it turns out that's very specifically the record Larry broke.

  • I use xonsh.

  • How do we feel about the situationists?

    Jump

  • I have been reading a book about them recently, so I have some feelings. On a general level, they were revolutionary socialists opposed to dictatorships like Soviet Union and China, so basically the good type of socialist if you ask me. It seems that they generally were critical of state as a concept, although I am not sure how critical exactly.

    On a more specific level, their theory of spectacle is quite hard to understand for me for some reason, but I think it basically says that the society makes us passive consumers of commodities and propaganda, which seems like a reasonable criticism.

    Also, reading about them has strengthened my wish to found an anarchist avant garde art collective.

  • Many.

  • Have they redesigned the Lego skeleton arms? I remember them being different.

  • Andre Geim got the Ig Nobel for this. He is the only person this far to have got both the Ig Nobel and an actual Nobel prize.

  • What desktop enviroment do you use and why?

    Jump

  • Well, Python is my main programming language, so things being made with it gives me a feeling that I can understand and control them. Sometimes this feeling is even right, for example with Qtile, which is also configured with Python.

  • What desktop enviroment do you use and why?

    Jump

  • Qtile, just because it's Python-based.

  • What is your favourite shell to use

    Jump

  • Xonsh. For basic use (running CLI programs with arguments) it works like any other shell, and for other uses it has nice Python syntax (and libraries!). For example, I like not needing a separate calculator program, as I can do maths directly in the shell with an intuitive syntax.

  • What's your favorite terminal?

    Jump

  • I like Terminator for its mouse-controlled multiplexing. I also like the fact that it's made with Python, although I haven't utilized this fact in practice.
