Nowadays when someone speaks of "art" you probably think first of "fine arts" such as painting and sculpture, but before the twentieth century the word was generally used in quite a different sense. Since this older meaning of "art" still survives in many idioms, especially when we are contrasting art with science, I…
The evidence is not only anecdotal. A recent study by Aaron Clauset, Samuel Arbesman, and Daniel B. Larremore shows that “a quarter of all universities account for 71 to 86 percent of all tenure-track faculty in the U.S. and Canada in these three fields. Just 18 elite universities produce half of all computer science…
Matrioshka Brains (MB)1 are megascale computers constructed out of microelectronic and/or nanoscale components. MB may be constructed as shells around a star (internally powered Matrioshka Brains: IPMB) or may be constructed independently of a star if large amounts of power are harvested from stars in other locations…
I have been a happy man ever since January 1, 1990, when I no longer had an email address. I'd used email since about 1975, and it seems to me that 15 years of email is plenty for one lifetime. Email is a wonderful thing for people whose role in life is to be on top of things. But not for me; my role is to be on the…
I worked with COBOL near the end of my last contract and found aspects of it fascinating compared to today's languages. Everything is about structures that map directly to the bits on disk, with fine grain control on precision and data types. But then the language reads as a series of macros where you don't have to…
C is a big language with a lot of features, and it’s easy to get lost in how fun it is. But you can’t really appreciate a feature without knowing what it’s like to do without. So do things with limited resources. Make a binary adder using falling dominoes. Make a functional digital clock with neon bulbs, resistors…
Like bilinguals, expert computer programmers successfully manage two or more separate lexicons, grammars and divergent concepts, avoiding inadvertent transfer between the two. Numerous studies of novice programmers indicate that they struggle to do achieve this division; transfer from natural language creates bugs…
A Cornell experiment in the 1960s polled a group of computer science students and divded them into those who liked to work with music in the background and those who didn't. They put 1/2 of each group together in a silent room, and the other 1/2 in a different room equipped with headphones and a musical selection. To…
So if you want to find a name in a phone book of a million names you can actually find any name by doing this at most 20 times. In comparing search algorithms we decide that this comparison is our 'n'. For a phone book of 3 names it takes 2 comparisons (at most). For 7 it takes at most 3. For 15 it takes 4. ... For…
Recent advances in fields ranging from cosmology to computer science have hinted at a possible deep connection between intelligence and entropy maximization. In cosmology, the causal entropic principle for anthropic selection has used the maximization of entropy production in causally connected space-time regions as a…
And for all their power and speed, today’s digital machines have shown little creative ability. They can’t compose very good songs, write great novels, or generate good ideas for new businesses. Apparent exceptions here only prove the rule. A prankster used an online generator of abstracts for computer science papers…
Seibel: You mention four disciplines: music, graphics, mathematics, and text those are about as old as humanity. Clearly there are powerful ideas there that are independent of computers—the computer just provides a way to explore them that might be hard without the computer. Is there also a set of interesting…
John Washbrook, who was himself a senior academic in the department, took me under his wing and he told me something that very important. He said, "Just start something, no matter how humble." This is not recall; about programming, this is about research. But no matter how humble and unoriginal and unimportant it may…
Seibel: Do you think of yourself as a scientist, an engineer, an artist, or a draftsman? Allen: I think of myself as a computer scientist I was involved in my corner of the field in helping it develop. And those were interesting times—the emergence of computer science—because there was a Ic lot of question about, "Is…
In other words, there's still so much more beyond any five pages of my book that you can make a lifetime's worth of study, because there's just that much In computer science. Computer science doesn't all boil down to a bunch of simple things. If it turned out that computer science was very simple, that all you needed…
So I don't envy modern programmers, and It's going to get worse. The simple things are getting packaged into libraries, leaving only the hard things. That stuff is getting so complicated, but the standards that people are expecting are stunning. One of the ones ^i^ey showed me stunned me. He was showing me Google Maps…
I have a little bit of a rant about computer science also. I could make a pretty strong case that the word science should not be applied to computing. I think essentially all of what's called computer science is some combination of engineering and applied mathematics. I think very little of it is science in terms oft…
George Malamidis taught me something about code attachment a few years ago: You always gain by allowing someone to show you an alternative solution. If someone wants to solve a problem in a different way, there are several gains to be had. If their way is inferior, you have an opportunity to mentor a team-mate. If…
Consider some fundamental names: Turing (computation theory and programmable automata), von Neumann (computer architecture), Shannon (information theory), Knuth, Hoare, Dijkstra, and Wirth (programming theory and algorithmics), Feigenbaum and McCarthy (artificial intelligence), Codd (relational model of databases)…
