It’s a frequent observation that computing has oscillated between centralized and distributed. We’ve gone from centralized computing facilities (which were effectively single-user, but only the administrators could use them) to time-sharing to personal computers to server farms. Data has moved from the card deck you kept in your office to the tape deck at the…

I’ve always found it easy to deal with machines, as I expect is true of most computer programmers. The interface to a machine is not always logical, but it is normally consistent in the sense that it always behaves the same way given the same inputs, and it is normally unambiguous in the sense that…

Back in March Go picked up a dynamic exception mechanism. Previously, when code called the panic function, it simply aborted your program. Now, it walks up the stack to the top of the currently running goroutine, running all deferred functions. More interestingly, if a deferred function calls the new recover function, the panic is interrupted,…

I’m very pleased to see that the GCC steering committee has agreed to permit GCC to be written in C++. At one time RMS, who is a member of the steering committee, had felt that C++ was never appropriate for systems programs like GCC. It’s good to see that he has apparently come around. There…

GCC as a free software project is clearly very successful. Over more than 20 years it’s grown from nothing to become the standard compiler for several operating systems and many microprocessors. So far in 2010 the core part of the compiler alone has seen over 1000 commits by over 100 contributors. GCC continues to get…
