![Programming languages on the whole are very much more complicated than they used to be: object orientation, inheritance, and other features are still not really being thought through from the point of view of a coherent and scientifically well-based discipline or a theory of correctness. My original postulate, which I have been pursuing as a scientist all my life, is that one uses the criteria of correctness as a means of converging on a decent programming language design-one which doesn't set traps for its users, and ones in which the different components of the program correspond clearly to different components of its specification, so you can reason compositionally about it. [...] The tools, including the compiler, have to be based on some theory of what it means to write a correct program. (C. A. R.

Don't forget that God sees you and watches you when you are in pain; He perceives even the beating of your heart. Consequently, He will not leave you without consolation and His fatherly protection. Naturally, the saints rejoiced in their afflictions; as for us, let us at least manage to accept affliction or pain patiently.
My child, pray within your heart, and the name of Jesus will become for you a comforting balm so that you can bear this trial of yours in a way which benefits you. You will greatly benefit from this trial if you submit yourself to it patiently. So again I say to you, with the almighty armor of prayer continually approach the omnipotent Lord more often, and you will come to know how He wondrously lifts the burden of pain and marvellously gives rest to sufferers.

So many young men of color become part of that officer's life experience because so many minority families and communities are struggling, so many boys and young men grow up in environments lacking role models, adequate education, and decent employment-they lack all sorts of opportunities that most of us take for granted. A tragedy of American life-one that most citizens are able to drive around because it doesn't touch them-is that young people in "those neighborhoods” too often inherit a legacy of crime and prison. And with that inheritance, they become part of a police officer's life, and shape the way that officer-whether white or black-sees the world. Changing that legacy is a challenge so enormous and so complicated that it is, unfortunately, easier to talk only about the cops. And that's not fair.

Magic and art tend to share a lot of the same language. They both talk about evocation, invocation, and conjuring. If you're trying to conjure a character, then maybe you should treat that with the respect that you would if you were trying to conjure a demon. Because if an image of a god is a god, then in some sense the image of a demon is a demon. I'm thinking of people like Malcolm Lowry, the exquisite author of Under the Volcano. There are kabbalistic demons that are lurking all the way through Under the Volcano, and I assume they were probably similar forces to the ones that eventually overwhelmed Lowry's life, such as the drinking and the madness. When I hear alcoholics talk about having their demons, I think that they're probably absolutely literally correct.

With the publication of J. M. Keynes's General Theory in 1936 and the mathematical formalizations of his theory by J. R. Hicks (1937) and others, the language of macro-economic theory became systems of simultaneous equations. These are general equilibrium systems of interdependence in the sense that the relationships describe an entire national economy, not just a particular industry or sector. The systems are usually not completely closed; they depend on exogenous parameters including instruments controlled by policy-makers. Seeking definite relationships of economic outcomes to policies and other exogenous variables, qualitative and quantitative, these models sacrifice detail and generality, limiting the number of variables and equations by aggregations over agents, commodities, assets, and time.

I like Sarah Palin, and I've heartily enjoyed her arrival on the national stage. As a career classroom teacher, I can see how smart she is - and quite frankly, I think the people who don't see it are the stupid ones, wrapped in the fuzzy mummy-gauze of their own worn-out partisan dogma. So she doesn't speak the King's English - big whoop! There is a powerful clarity of consciousness in her eyes. She uses language with the jumps, breaks and rippling momentum of a be-bop saxophonist. I stand on what I said (as a staunch pro-choice advocate) in my last two columns - that Palin as a pro-life wife, mother and ambitious professional represents the next big shift in feminism. Pro-life women will save feminism by expanding it, particularly into the more traditional Third World.
