   Oh, you're right. I just glanced over the equation and I thought I should recommend the standard notation. But as you stated, the cross product is clearly wrong as given by the author. There's obviously no other way than defining

   I've never seen a cross product being defined in that way using Einstein notation. You might want to express the cross product using the Levi-Civita symbol epsilon_{ijk} [1]. epsilon_{ijk} = 1 for i,j,k = 1,2,3 and all even permutation

   I think this is a general problem for people used to the comfort of compiled languages. I also struggle with languages like JavaScript. I always have the feeling that I'm actually doing something wrong or non-standard but the webbrowse

   Considering that you can't really use music streaming with the usual caps here (200MB, 500MB, 1GB, 3GB), it makes it impossible to compete with Spotify, unless you also pay DT. Therefore, in the context of mobile, all other music strea

   Mostly depressing. Basically the Telcos are acting in the same way as the ones in the USA. But we didn't have such an uproar from the people without which, I assume, the new NN rules couldn't be established in the USA. Politicians

   Congratulations to all the people who've put so much effort into this. It's a good day for the internet. I hope some day something like this will happen in Germany as well.

   Thank you for the explanation!

    Is it? Doesn't Wikipedia actually put the source code of the LaTeX equation into the alt attribute? That's what I did. I'm not an expert on accessibility but I thought that this is the way to go...?

    Is MathML actually widely used? I can't believe anyone would really want to use something else than the LaTeX stuff for typesetting formulas. There's nothing as pretty as LaTeX for that. Recently I wrote a small tool that enables

    > I am surprised by how often I hear this example. Huh? That surprises me, too. I didn't know it was so common. Anyway, I agree that there is an equivalence between a function and its graph. Knowing one implies you know the other. B

    Please write a vim plugin for that and let me know :)

    I agree with your first point. I don't see designers learning to represent ideas as equations. Not even most of the people who studied Computer Science know the difference between a function and the graph of a function. So I don't

    The reason I told you that I didn't know about California's electricity crisis is that I didn't have too much time on my hands to figure out what you meant. I'm perfectly capable of figuring things out myself, if I want

    Actually, the price (for the OEM) of buying completely integrated components is lower than buying separate ones. However, OEMs don't like to show that to customers. So each step in upgrading RAM or SSDs or whatever is worth $100 or mor

    If I understood correctly, you are trying to get a sentiment that is always correct for single sentences but that can extrapolate word frequencies if they don't appear in your list. I.e. for large neutral documents you want it to be ne

    I don't think you can really avoid it when trying to pack everything as densely as possible. A few years down the road, I believe, an SoC will probably contain not only the CPU, graphics, audio, etc., but also RAM. Probably stacked ont

    Almost all phones nowadays come with a large range of frequency bands within which they can send and receive. Towers themselves are not the problem, AFAIK. The network infrastructure to the towers is problematic, though. If the infrastructu

    It certainly wasn't my intention to alienate or offend anyone by posting this link. I do not share his intimate feelings on programming languages but I found it amusing that someone would compare a programming language to an on/of

    It's about programming languages! :D Although, I think, if someone reads it who's not familiar with programming languages, the reactions, when you tell them what Haskell and Python are, might range from hilarious to WTF.

    This is madness. It doesn't make any sense, whatsoever, to sell wireless frequency spectrum, except a quick injection of money into the government's treasury. It only promotes monopolies and pushes new comers out of the market. In

    Haskell is such a great language. I've been recommending this book for a while now. If you are in doubt whether you should start learning it, read this post by Jeff Bone: http://www.xent.com/pipermail/fork/Wee
