Comment on Where to find free Classical music by Noldorin's Blog » Blog Archive » Musical Gem of the Week #3 - Musings on my countless projects, software, science, and various other curiosities

[...] This wonderful recording by Raffaele Terlizzi, is again of very high quality and free to download. Although I’m hardly informed to judge, it would seem that this performance was made on a fortepiano (an instrument of Scarlatti’s day, as opposed to the more modern pianoforte) – either way, it gives a feeling of contemporary authenticity. On the subject of online recordings, you can find a immense number of great recordings of piano/keyboard music available for download from the Piano Society website (which I somehow managed to miss out from my previous list of resources for free clasical music).

Comment on The Traveller’s Paradox by David Laban

So I got as far as:

“P(X) \equiv \text{the question to ask giant} X; \text{returns the yes/no answer}

… First, observe that whichever giant you ask, the reply you get will be either P(1) or \neg P(0) in response.”

and got stuck. It took me a while to get over my urge to treat P(.) as the probability operator, but then there were other things that don’t make sense:

I translated the first statement into P(X) === “The answer to your question is ‘yes’, given that you ask your question to giant X”. Is this right, or do your seemingly ambiguous “yes/no”, ‘;’ and awkwardly worded “to ask giant X” actually make that statement mean something very specific in propositional calculus?

The problem is that if my translation is correct, then the second statement I quoted can’t make sense. It seems that if you ask giant 1 then you will get P(1) as your reply and if you ask giant 0 then you will get P(0) (not ¬P(0) as your statement seems to suggest) as your reply.

So yeah… I’m stuck. Ping me on gtalk when you have the time to explain.

Ah, good to know! No need to elaborate too much, I’m glad just to hear that much, heh.

Hope the exams are all going well, by the way.

Hey, I’m reading, just don’t have the opportunity to expand on it at this point! Once I have a little more time to listen to music I’ll take a listen.

Comment on Markov Chain Generator in .NET by Noldorin

Yeah, I also thought about maintaining a list of (count, node), but it would seem to complicate the implementation a fair bit, in the way you say. We’ll see, though – I might end up using that approach anyway for the sake of memory efficiency.

If I ever get around to expanding my sample bot, I’ll definitely have a look at modifying the code to work with higher-order Markov models. Since I’m just trying to show off my IRC lib, and not really the wonders of Markov chains, that may not happen soon however.

Looks like a pretty simple implementation. I’d probably be tempted to keep links as a list of (count, node) but in your case count would probably be 1 most of the time and it would just complicate your sampling.

I guess it depends how big you want your training data to be. In your case, with a 1st order markov model there’s no point in training it very far. Read the intro to Shannon’s paper for a simple exploration of other markov models.

Comment on Electronic Lecture Notes Revisited by Noldorin

Oh, but I think rather highly of history students, for that matter! I’ve made a few updates to the post anyway, being more awake this afternoon, so you’re now specifically in the category of law students.

Anyway, I’m glad you’ve replied to this post, as there is now at least some evidence that taking notes on an Eee PC does work when you don’t have to write equations! Which model do you have, by the way? A slightly newer one, if I remember right. And no indeed, David installed plain old (Gnome) Ubuntu on the thing some time ago. Regarding equations, having a graphical user interface for writing them wouldn’t be a great advantage as I see, but then I don’t see how it could get much more painful that entering raw LaTeX…

Oh well, I’m not exactly wanting to complain here, given I have notes right in front of me that are better than any I could ever take.

While I’d hate to be lumped together with the history students, the Eee PC is very useful for notes that are (almost) entirely simple text; I really couldn’t be without mine now. I have some problems with the size of the keyboard, but bearing in mind each day I’m generally using three different keyboards, I don’t tend to notice the difference between changing from a smaller to larger keyboard any more than from a full-size laptop keyboard to a generic one.

Given the amount of bitching I heard about it, I’d be amazed if the Eee PC you’re using still had Xandros, but I seem to remember seeing something for writing equations when I was using it.

I’ll take a crack at a build and test when I get my next Windows workstation finished and let you know how it goes.
