Re: Old PC vs. New

the notion that Dell "designs" or "engineers" in quaint... these days it's ODMs that do that.

Re: Old PC vs. New

You may want to check the multiprocessing details of the software environments you will be using... most Lisp implementations still have some form of "global interpreter lock" or single-threaded memory allocator, which would reduce any benefits of multiple cores or HT.

Re: How to measure time?

nail, head, hit. I've disabled the on-screen clock on my computers. It was (rather surprisingly) very scary at first. I suggest everybody try it as an experiment ;) You might be surprised how often you subconsciously are checking the time... See J.G. Ballard's story "Chronopolis" in this ...

Re: Crimson skin removal

the skins on power series and crimson are pretty robust. the plastic is very heavy and dense and they have metal studs molded in that clip into the chassis. what I would do is take a 1/4 flathead screwdriver and gently pry all around at places where you suspect studs could be hidden. you should be a...

not so... Rotel RB-5000 and RC-5000, for example, were almost always sold as a set.

Re: New Indigo2 user

the indigo2 prom is smart enough to set the block size to 512 bytes if the drive supports the MODE SELECT BLOCKSIZE command.

Re: NVRAM for Sparcstation 20

as long as you choose a sysid that is a valid unicast MAC address, the onboard ethernet should work with any address you want. the reason for keeping the same address is for software licensing, and to avoid confusing routers/switches that have the station MAC address stored, for VLAN assignment, pro...

Re: O2 and crystal eye glasses

yes, the presenter board has a minidin-3 stereo connector. But the stereo sync signal may be available from another place within the IP32 itself.

Re: dillo errors

This may be a naive suggestion, but couldn't you use a C99 cpp pass using -P and run CC on that?

Re: dillo errors

man cc: * The gcc compiler allows variadic macros; the MIPSpro 7.4 compilers support these macros in c99 mode. If you have code that uses ellipses (...) as part of a macro definition and you are not compiling with c99, you will need to rewrite the macro. Two possible approaches are to replace the ma...

Re: Unicode-encoded source code files and MIPSpro compilers

I'm not aware that it handles them at all, that is, the symbols are used in whatever encoding they appear in. This would only work by accident considering all the composed/decomposed, surrogates, extended planes issues. All separate from the programming language specification.
