Re: i486 and i686 are the majority ISAs for x86 -- WAS: CentOS 4.0 -> 4.1 update failing
...- and that includes the Pentium
Pro on-ward, which are i686 ISA.
The i686 ISA and designs fix a massive amount of serious design
errors made in both the Pentium ALU itself as well as considerations
in its i586 ISA. To be fair to Intel, it was their first superscalar
design. But at the same time, NexGen was able to pull off an even
better, superscalar ALU, and much of Intel's "design assistance"
came indirectly from joining Digital on the Alpha chip briefly.

rsync wont work
can someone tell me what am i doing wrong?
d# rsync -vcrlpogtz . rsync@domain.ltd:/rsync/
rsync@domain.ltd's password:
sh: rsync: rsync: connection unexpectedly closed (0 bytes read so far) rsync
error: error in rsync protocol data stream (code 12) at io.c(189)
d#
it works fine if i just specify directory instead of remote site, but thats
not what i need..
thanks in advance

Re: Demonizing generic Linux issues as Fedora Core-only issues -- WAS: Hi, Bryan
...reason why Linux projects fail.
Having a background in defense, I liken this to NASA's COTS (commercial
off-the-shelf) adoption in the '90s. After Sojouner (Mars Pathfinder)
proved that GNU/VxWorks was a viable platform that cost 1/10th of
custom software/hardware development, NASA's nexgen probes started
adopting the same platforms/software as Pathfinder.
The problem on these other projects is that the 90% savings was no
longer applied to just software/hardware, but _all_ aspects of the
project's budget. So unlike Sojouner, the QA (quality assurance) budget
was cut. So when Ma...

[OT] Memory Models and Multi/Virtual-Cores -- WAS: 4.0 -> 4.1 update failing
...ISA -- Nx586+FPU/K5*, Nx686/K6
- Superscalar: 3+1 ALU+FPU (ALUs pipelined, FPU _not_ piplined)
AMD Gen 3 (1999): i686/x86-64 ISA -- Athlon, Athlon64/Opteron
- Superscalar: 3+3 ALU+FPU (pipelined), FPU 2 _and_ 1 ADD/MULT
- Extensions are microcoded and leverage ALU/FPU as appropriate
*NOTE: The NexGen Nx586 released in 1994 forms the basis for
latter K5 (i486) and the K6 (i686). AMD had scalability issues with
its original non-superscalar K5 design and purchased NexGen.
SIDE NOTE: SSE Comparison
- P4 can do 3 MULT SSE (1 FPU complex + 2 SSE pipes)
- Athlon can do 3 MULT SSE (2 FPU complex + 1...
