d extend till the end of a single command: ; & && and
|| should stop it.
Note that it's the first time I use yacc, so probably there is a better way
to code this and there are probably bugs.
For example I was unable to make this works:
% $ echo ./configure --prefix=`{cat /env/
In Jehanne, I decided to test both: if the queue is not closed there's no
need to check up->errstr.
Thanks for your help!

lot for your

And as long as you align with their purposes they will threat you as a peer.
It's not that those developers are evil but there's a large amount of
politics inside these companies they have to cope with.
And ultimately, the companies that pay them are not pursuing values, just
long term profits.

As far as I can remember plan9 flush tables very often and clearly

So my dumb question is: are plan9/9front and friends actually
vulnerable to Meltdown?

@Rui: Jehanne diverged a lot from Plan 9, in a pursuit for my vision
of simplicity.
While it's in no way a Unix, many won't even consider it a Plan 9
system. Still for anyone interested: http://jehanne.io

Probably C. But I wonder if a more high level language could make the job
easier without increasing too much the project scope.
So far candidates alternatives (that I still need time to evaluate deeply)
are Wirth's Oberon-07 and Obi's Myrddin.

The blocking system call used in sleep is rendezvous that, in Jehanne,

It was hypothetical. But, to keep back your cart you MUST be logged (some
times adding to the shopping cart don't require authentication) and the cart
status have to be saved somewhere (the database?).
Note that such a strategy could lead to problems too: what about if you fill
a shopping cart with discounted products and submit it a month later, when
discounts disappear?
Are you sure you would be check if the prices have changed? I think so...
you use Plan 9...
But customers, often, use Windows... they are not so smart! :-D

hable results (SELECT, FETCH, SHOW...) require a tool

Hello list,
I've found in http://netlib.bell-labs.com/wiki/plan9/Contrib_index/ the xml2
(libxml2-2.6.30 for APE) package from Federico G. Benavento.
I was wondering if I have to use all the APE to use the library for writing
a Plan 9 application.
Giacomo
Anyone know if with such a library I could write an application on linux
mountable from Plan 9?
I've understood it could be used for syntetic fs accessible from the local
machine (as for wmii), but what about accessing such filesystem from
outside?
Giacomo
Ehm... Sorry... :-D
As I knew libxml2, I directly searched "libxml2" in the contrib page...
You're right... I'll use that. :-D

Hello 9fans,
browsing the 9p.io's sources of plan9 I have noticed that u9fs have a
specific LICENSE file that is not MIT, while the page header says
"Distributed under the MIT License".
What's the actual license under which u9fs is distributed by the
Plan 9 F
and the "free of
charges" is clearly referred to the permission:
https://opensource.org/licenses/MIT

But I think that to avoid future issues, the Plan 9 Foundation

Cancelling Nemo is not a political achievement.
Building on the great work he donated to this community, is.
