Hi.
Does anyone know how to add swap space on a System V Release 2 system?
In particular, on an emulated AT&T 3B1. The kernel is S5R1 or S5R2
vintage.
I don't see any commands with 'swap' in their names.
Thanks,
Arnold
I'm writing about my 5 favorite unix design principles on my blog this
week, and it got me wondering what others' favorite unix design principles
are? For reference, mine are:
- Rule of Separation (from TAOUP <http://catb.org/~esr/writings/taoup/html/>
)
- Let the Machine Do the Dirty Work (from Elements of Programming Style)
- Rule of Silence (from TAOUP <http://catb.org/~esr/writings/taoup/html/>)
- Data Dominates (Rob Pike #5)
- The SPOT (Single Point of Truth) Rule (from TAOUP

All PDP-11 Unix versions from V4 on require the MMU, so the -11/03 is out for
them. We don't have the code for V2-V4, though. So V1 (mostly all assembler,
no C :-), LSW and Mini-Unix are the only options for it.
V6 can be run on an -11/23 (I've done it), but not straight out of the box;
it requires a few minor tweaks first:

A problem that shouldn't have ever been there in the first place. When
I was at EDS, we did a lot of benchmarks against token-ring vs.
CSMA-CD. Token-ring was slower than CSMA-CD until the traffic got to
be more than about 10% of capacity - then the collision detection
exponential backoff algorithm would clobber the network. The argument
that "well, we will never get above that anyway, so we want the
fastest we can get" sort of short-sightedness won the day. It wasn't
until switches and virtual LANs came into existence that (as you said)
solved the problem.

Hi folks,
In case you're interested:
I've published a couple videos on these ancient Unix tools, sharing
including some language details and showing them in action on v7 and
System III, respectively:
Ken Thompson's bas(1): https://youtu.be/LZUMNZTUJos
Dick Haight's bs(1): https://youtu.be/ELICIa3L22o
Thanks much for the help from TUHS, Mashey, Kernighan, McIlroy, and
others cited therein.
Peace,
Dave

Not really. I've seen bare faces and beards and operating systems
over the decades that would scare the bugs out of any of the above
beards and operating systems. There really isn't a lot of consistency.
I've known plenty of bare-faced UNIX hacks, and plenty of RSX and
VMS and Windows and IBM programmers who hide their embarrassment
behind beards.
The ultimate reference is, of course, the inhabitants of the UNIX
Room. During my time there in mid-to-late 1980s, some people wore
beards, some didn't. I have never seen Ken or Dennis or Brian
clean-shaven, but I have never seen Doug or Rob or Tom Duff or
Lorinda with a beard.
And despite a certain remark attributed to the late Vic Vyssotsky
(who I've never seen with a beard either), I am quite sure that
my appearance had nothing to do with my being recruited by the group.
