i forgot to attach the recipie for disaster.

by using the following program.

Re: [9fans] mk (from plan9ports) modification time resolution issue?
But the above statement is true unless you have about 367 targets (for quite a small project -- only 2 tiny and 1 larger Erlang applications), which when built takes about 45 seconds (with NPROC=16), and the second time (without touching a single file in the source directory) takes about exactly the same amount (still 45 seconds), the third time goes down to 44 seconds, then 43 seconds, then 7 seconds, then 1 second, then 0.6 seconds, then 0.2 seconds, then again 0.2 seconds, again 0.2 seconds, again 0.2, again 0.2, again 0.2, and finally after ONLY 13 builds it finds out that nothing is to be made... sleep 1; mk Russ
Re: [9fans] how to make hardware work?
What exactly do you mean, PPP over USB? Google PPP over USB. I've googled, red 9fans archive, wiki and docs before posting here. In theory, your 3G data stick should export a serial device interface, and therefore usb/serial should map it to /dev/eiaUx/eiaUx (where x is a small integer). (See usb(4)). You would then run, e.g., 'ip/ppp -p /dev/eiaU0/eiaU0 ...' (see ppp(8)). --lyndon
[9fans] Fwd: plan9 go output faults on 9vx with rfork
Pavel built a reproducer and sent it to me:

From: Pavel Zholkover paulz...@gmail.com

Subject: Re: plan9 go output faults on 9vx with rfork

Hi Ron!
I think I've traced the cause of the crash. It is unfortunately the
syscall semacquire.
The following C program will crash vanilla 0.12 9vx and the one I
compiled from your branch:
#include u.h
#include libc.h
static long l=1;
void main(int argc, char *argv[]) {
int i;
semacquire(l, 1);
for(i=0; i 99; i++)
;
semrelease(l, 1);
exits(nil);
}
---
Got peace and quite and a bulkhead seat to PHX, so had time to look.
The problem was that cmpswap was never set to anything in 9vx, so the
first time canacquire was used, well,
kaboom, since canacquire was NULL.
Changes can be seen here:
https://bitbucket.org/rminnich/vx32/changeset/c7ba21bd847c
My fix is in 9vx/main.c to do this:
cmpswap = oscmpswap;
What's oscmpswap? Well, for darwin, it is defined in 9vx/os/cmpswap.c
You can see the rest of the changes; you can also see that this won't
build on Linux until we fix it; left as an exercise for the reader, or
until I get back home and fix it.
The reproducer no longer crashes 9vx. Now, the question is, what's
next to make Go work on 9vx?

In the days before I took up electronics as a hobby, valves were seated in sockets because it was known that the equipment they were used in would outlive them. Maybe we should recommend easily replaceable capacitors in modern equipment instead of blindly accepting that a component of extremely low cost should wreck expensive machinery beyond repair. Cheap caps don't last, expensive ones do. No-one's going to put cheap caps in sockets, it defeats the point of using cheap ones. Cap replacement is still possible if you have some skill with a soldering iron, or see http://badcaps.net/ . That said, adequate caps are often larger than cheap ones.

Re: [9fans] plan9 compatible notebook
I've tried Thinkpad models X200s, X201, and X300 with Plan 9. Each of them PXE booted over ethernet (with the Intel cards) and using the local file server as root fs. Graphics, input, etc. work very well and Plan 9 runs very smoothly here. I haven't tried sound or anything. I boot into Plan 9 on my Thinkpad (the X200s) only occasionally, since I have another machine to serve as a terminal already. So, I haven't had chance to try everything. Of course, there is no WiFi - and in my setup, where the root fs is a Ken FS file server on the local network, and remote booting is required, I doubt there would be any use for it either.
