There *is* nobody official who could do it -- that's why it can only evolve into reality through consensus. Magnus seems to be steering things in the right direction for that. All organizations, official or otherwise, are formed by a group of people getting together and collectively stating, "We are hereby an organization." There was never any other way. Officialdom is granted to an organization from the outside, something that the proposed Linux Consortium can fortunately forego entirely (who would grant us officialdom? IEEE? ISO? ACM? UNESCO?). All it takes is for us -- Linux users, developers and distributors -- to get together and collectively state, "We are hereby an organization." This is exactly what Magnus is trying to lead up to, as I have understood it. Once the organization has created itself, then all else is logistics: decide who might best be qualified to do some testing *on behalf of the organization* and such. -- Mark ==================================================================== Mark P.

Last night I did something incredible stupid! (I guess I was tired, that's an excuse ...right ?). I was going to run iozone on my scsi disk /dev/sda1, and I did'nt really remember the syntax, so I just wrote: iozone 1 /dev/sda1 (trying to run it on dev/sda1...) This caused the whole system to hang! I guess the syntax is: iozone , that is iozone writes file size bytes to file name... So, I guess i have written directly to the patition!

In other words, if you run some calculations on a machine with 4 486's, it won't be faster, than when you run it on your PC with 1 486 (if clocks are the same, etc.). However, most modern Unix'es do no longer create a fixed process to processor mapping. Any process can run on any available processor. Allowing one job to be executed by multiple processors in parallel requires lots of synchronization for data to be available, etc. There are experimental compilers for computers like the connection machine, etc. Perhaps, they are much more ALPHA than anything of Linux. Most multiprocessor machines marketed today have their use as terminal, database, or whatever servers only. You get a good, maybe even linear speedup here, because of the big number of connections and thus jobs running. You may also see some speedup, where processing is done by seperate processes. Think of X server and X client, which then can be run on seperate processors. Or use the "-pipe" option with the gcc compiler, which will run the preprocessor, the main compiler and the assembler at the same time. This options even speeds things up on a single user system - when the preprocessor waits for the disk to read a certain file, the compiler can start with its work, etc. Kai Petzke -- Kai wpp@marie.physik.tu-berlin.de Advertisement by Microsoft in a well-known German magazine: If you don't like our programmes, than make your own ones.

The problem is, that the SVGA - Mode switching is done by BIOS. Well, after starting Linux, BIOS is mostly disabled, except for DOSEMU. I would like to have different SVGA - Modes on different VC's. I know, it is possible, because I can have graphics mode and X on VC 7, DOSEMU and 80x25 on VC 4, and 100x40 on all others. A possible way of implementing a free graphics mode switch, is to write a DOS programme, which reads and saves the SVGA registers, and a Linux system call, which sets the SVGA registers to the saved values. But why not go for the real thing? X allows you to specify modes with any number of lines, columns and frequencies. Why not allow the same for VC's? Just a thought.
