Trees sprout up just about everywhere in computer science.

A code, which according to Turing's schema is supposed to make one machine behave as if it were another specific machine (which is supposed to make the former imitate the latter) must do the following things. It must contain, in terms that the machine will understand (and purposively obey), instructions (further detailed parts of the code) that will cause the machine to examine every order it gets and determine whether this order has the structure appropriate to an order of the second machine. It must then contain, in terms of the order system of the first machine, sufficient orders to make the machine cause the actions to be taken that the second machine would have taken under the influence of the order in question.

A good standalone plugin can also make you a fair amount of money. Many developers make a decent living by simply maintaining and updating one or two crucial plugins that are far better than anything available for free.

An activity originally intended to be performed by low-status, clerical – and more often than not, female – computer programming was gradually and deliberately transformed into a high-status, scientific, and masculine discipline.

Any artificial automaton that has been constructed for human use, and specifically for the control of complicated processes, normally possesses a purely logical part and an arithmetical part, i.e. a part in which arithmetical processes play no role, and one in which they are of importance.

...artificial intelligence will become a major human rights issue in the twenty-first century.

Automation vs. human labor is a false dichotomy

Bombe atomique hier, bombe informatique aujourd'hui et, demain, bombe génétique?

El hecho es que el ordenador está aquí para quedarse y los niños saben utilizarlo y nosotros no. Incluso el lenguaje.

Evolution optimizes strongly for energy efficiency because of limited food supply, not for ease of construction or understanding by human engineers.

Ich langte in meine Tasche nach einem Milky Way - was sonst für einen Astronomen - und machte es mir bequem, um den Hacker auf meinem grünen Monitor zu beobachten.

If the brain had a native language we would be able to communicate with all humans without translation. Or even all other creatures on earth.

A few years ago a friend said that I use to hunt and fish and build houses and things but now my whole life revolved around my computer I replied "But my computer revolves around the world

AI research can have irreversible repercussions in the life of the human species, so we must tread cautiously.

AI can be programed to imitate human behavior only, but it can't be programmed to feel the emotions that make the humans behave the way they do.

All existing machines and memories use "direct addressing," which is to say that every word in the memory has a numerical address of its own that characterizes it and its position within the memory (the total aggregate of all hierarchic levels) uniquely.

And they came to be included in a culture and community that placed the computer science engineer at the highest level of social status.

An international power supply is the device which means it doesn't matter what country you're in, or even if you know what country you're in (more of a problem than you might suspect) - you just plug your Mac in and it figures it out for itself. We call this principle Plug and Play. Or at least, Microsoft calls it that because it hasn't got it yet. In the Mac world we've had it for so long we didn't even think of giving it a name.

Artificial intelligence is nowhere near attaining actual sentience or awareness. And without awareness it’s simply a mechanical device, which may pretend to show emotions and sentience, if it is programmed to do so, and thus it may be able to fool the humans as being alive, but in its own internal circuitry, it’d simply be following its preprogrammed tasks through the flowchart of an algorithm.

A system of logical instructions that an automaton can carry out and which causes the automaton to perform some organized task is called a code.

believe the power of jQuery is highly underutilized. Most developers will take advantage of its shortcuts and CSS selectors, but most of the time they fail to take advantage of much else. Being able to extend jQuery, whether by adding your own functions, CSS selectors or full-blown plugins, makes you a much stronger and smarter developer.

Computers and mobile devices are becoming known for their inherent insecurities and the ability to damage the long term health of the users.

Computer science increasingly relies on its private corporate patrons who apply their own closed systems of peer review and criticism, with occasional results thrown over the wall. The closed walls of Redmond or Mountain View enable old-fashioned patronage of nature's secrets. The objectivity and scientific status of computer science is a chimera: we cannot stand on the shoulders of giants in computer science, for they simply refuse to let us.

Computation is not the same as thought and emulation is not the same as imagination.

El desarrollo de software comparte con el deporte profesional la característica de lograr que los treintañeros se sientan decrépitos

Generating a system architecture is not a deterministic process. It requires careful consideration of business requirements, technology choices, existing infrastructure and systems, and actual physical resources, such as budget and manpower.

If you are too lazy to cleanup your database after testing, your filesystem after testing or your memory based system consider moving to a different profession. This isn't a job for you.

I hope the field of computer science never loses its sense of fun. ... What you know about computing other people will learn. Don’t feel as if the key to successful computing is only in your hands. What’s in your hands I think and hope is intelligence: the ability to see the machine as more than when you were first led up to it, that you can make it more.

Il fattore umano è l'anello più debole della sicurezza

I’m glad someone’s finally giving ed the attention it deserves.

In search," Urs (Hölzle) believed, "the discussion was really, How can we outdistance our current system and make it look laughable? That's the best definition of success: if a new system comes out and everyone says, 'Wow, I can't believe we put up with that old thing because it was so primitive and limited compared to this.

In the history of ideas, it's repeatedly happened that an idea, developed in one area for one purpose, finds an unexpected application elsewhere. Concepts developed purely for philosophy of mathematics turned out to be just what you needed to build a computer. Statistical formulae for understanding genetic change in biology are now applied in both economics and in programming.

I think that it’s extraordinarily important that we in computer science keep fun in computing. When it started out it was an awful lot of fun. Of course the paying customers got shafted every now and then and after a while we began to take their complaints seriously. We began to feel as if we really were responsible for the successful error-free perfect use of these machines. I don’t think we are. I think we’re responsible for stretching them setting them off in new directions and keeping fun in the house. I hope the field of computer science never loses its sense of fun. Above all I hope we don’t become missionaries. Don’t feel as if you’re Bible sales-men. The world has too many of those already. What you know about computing other people will learn. Don’t feel as if the key to successful computing is only in your hands. What’s in your hands I think and hope is intelligence: the ability to see the machine as more than when you were first led up to it that you can make it more.

I was transformed...because I caught a glimpse of a revolutionary use for computers. We seized the opportunity to the computer as a general processor for symbols (hence thoughts) rather than just a speedy engine for arithmetic.

Lilah did little more than sleep and eat and cry, which to me was the most fascinating thing in the entire universe. Why did she cry? When did she sleep? What made her eat a lot one day and little the next? Was she changing with time? I did what any obsessed person would do in such a case: I recorded data, plotted it, calculated statistical correlations. First I just wrote on scraps of paper and made charts on graph paper, but I very quickly became more sophisticated. I wrote computer software to make a beautifully colored plot showing times when Diane fed Lilah, in black; when I fed her, in blue (expressed mother's milk, if you must know); Lilah's fussy times, in angry red; her happy times, in green. I calculated patterns in sleeping times, eating times, length of sleep, amounts eaten. Then, I did what any obsessed person would do these days; I put it all on the Web.

More importantly, it is difficult to study minds because we are mental beings. We have our own minds to maintain and protect, and may not wish to discover facts that force us to change, or make us question our own being in the world, or conflict with our sense of right and wrong. We have not discussed belief systems known as religions to any extent in this book. However, particularly threatening are facts that run counter to our religious beliefs, especially if those beliefs are strongly held. Further, scientists have hopes, standards, and ethical beliefs, and they—like anybody—are not eager to find that their beliefs are invalid.

Most improved things can be improved.

No program can say what another will do. Now, I won’t just assert that, I’ll prove it to you. I will prove that although you might work till you drop, You cannot tell if computation will stop.

Overstimulation has been the real drawback. I need to find ways to stop thinking about analysis of algorithms, in order to do various other things that human beings ought to do.

Q: Why bother doing proofs about programming languages? They are almost always boring if the definitions are right. A: The definitions are almost always wrong. - Anonymous

Reusability is key in reducing bugs and coding quickly. The more I use a piece of code, the more confident and familiar I become with it, which in turn significantly speeds up my development time.

Simple things should be simple, complex things should be possible.

...if you aren't, at any given time, scandalized by code you wrote five or even three years ago, you're not learning anywhere near enough

Index design is also a largely iterative process, based on the SQL generated by application designers. However, it is possible to make a sensible start by building indexes that enforce primary key constraints and indexes on known access patterns, such as a person's name. As the application evolves and testing is performed on realistic sizes of data, certain queries will need performance improvements for which building a better index is a good solution.

In my experience, requirements change quite often, or new situations will arise that weren’t anticipated at the start of the project. If the situation can be addressed with a plugin, I just whip open the standalone plugin page, make the updates and pop the new plugin back in. Because the plugin is self-contained, it’s easy to recreate the problem, fix it, and get it back into the codebase.

In the end, it all comes down to 0 and 1

It can be argued that the computer is humanity’s attempt to replicate the human brain. This is perhaps an unattainable goal. However, unattainable goals often lead to outstanding accomplishment.

It is possible to invent a single machine which can be used to compute any computable sequence.

I wish to add my mite towards expounding & interpreting the Almighty, & his laws & works, for the most effective use of mankind; and certainly, I should feel it no small glory if I were enabled to be one of his most noted prophets (using this word in my own peculiar sense) in this world.

Perhaps the most important principle for the good algorithm designer is to refuse to be content.
