[9fans] Acme column layout box and buttons
Hello, Acme likes to place new windows itself. If you prefer to change the layout of a window, you only need to drag the /layout box/ at the left of the tag line and drop it somewhere else. The point where you drop it selects the column where the window is to be placed now, as well as the line where the window should start. You can also click the layout box to enlarge its window a small amount (button 1), as much as possible without obscuring other tag lines in the column (button 2), and to fill the whole column vertically (button 3). You can get your other windows back by clicking either button-1 or button-2 on the window layout box. That's a lot of good actions attached to all the three buttons for handling vertical layouts. How about adding similar actions to all the three buttons for managing horizontal layouts to a column /layout box/. -- Balwinder S bdheeman DheemanRegistered Linux User: #229709 Anu'z li...@home (Unix Shoppe)Machines: #168573, 170593, 259192 Chandigarh, UT, 160062, India Plan9, T2, Arch/Debian/FreeBSD/XP Home: http://cto.homelinux.net/~bsd/ Visit: http://counter.li.org/

I'd say that the biggest reason for DB overuse by Web folks is the fact that this is how they get persistence for their data while still being able to build distributed applications. In general, there are only two ways of having persistent data: * DBs * FSs (well, ok, there's third these days) FSs (under most OSes) have been way to clunky in the presence of any kind of distribution. Hence the DBs. i agree that this is the general line of thinking, but i think option #3 is missing. there's lots of ephemerial data that doesn't make sense to keep in a database even if you have one. if you do cc processing, some of it may be unwise to let the cgi see or illegal to store in a database (example: the verification code from the back of a credit card). so i always thought it made sense to have a session server to deal with these problems. we kept the connection information fit to keep in the filesystem. that was pretty easy. - erik

How about adding similar actions to all the three buttons for managing horizontal layouts to a column /layout box/. I had a patched version of acme to do this. It is not such a trivial thing as it looks like, but it is not difficult. However, it doesn't work so good in practice as in theory. I found disturbing that after pressing the right button the column was moved to the first place, and doing it without moving the column was a mess because of the mouse events (at the end I think I just moved the column to the first place and then back to its previous position). Other problem I had was that I didn't have very clear what to do with the middle button (taking the maximum space and having small columns is not a practical thing). On the other hands, growing columns with the left button is an easier thing (once you decide all your heuristics). Anyway, it was my first look into acme code and there probably are better ways to do it. What did you have in mind? -- - yiyus || JGL .
Re: [9fans] Acme column layout box and buttons
Seems logical, but I personally never felt a need for this. To prevent line breaks I normally end up moving the windows to an other, bigger column...

Re: [9fans] (no subject)
Give or take that all the executables fail, I have enough MINGW binutils from the NetBSD package to convince me that MINGW can be built and no doubt some debugging will soon take care of the stumbling blocks. It is true that debugging is going to be hard without symbol information (one more good reason to go the ELF route for my GCC model, in my opinion) and that I need a real implementation of the SEEK syscall before I start on the debugging, but these are surmountable obstacles. I guess you need to keep holding thumbs. Sorry, this went completely over my head. It sounds like you have achieved somthing impressive but I'am afraid I don't understand. -Steve
[9fans] rio in rio and ghost windows.
Test case:
draw a window... run rio
inside that thing draw another window and hide it.
now rezise the rio window.
now, the region where the window was seems to eat
mouse events, but the window is hidden.
Fix:
in rio.c:^resized, change this:
...
if(ishidden)
im = allocimage(display, r, screen-chan, 0, DWhite);
else
im = allocwindow(wscreen, r, Refbackup, DWhite);
to this:
if(ishidden){
im = allocimage(display, r, screen-chan, 0, DWhite);
r = ZR;
}else
im = allocwindow(wscreen, r, Refbackup, DWhite);
can anyone confirm this and may make a patch?

Re: [9fans] just in case anyone has written this
the p9p version of xcpu used to do something similar, but the old svn repository is gone now so i can't verify. i see an old version of rx.c in 9grid:/usr/andrey/src/xcpu/rx.c which does something similar to what you want with threads, channels and procs but doesn't combine the input. it doesn't look finished, so it may be useless. it creates a proc for each remote host :( it does something like this (from a perfunctory look, it's been a while): --- # shared between all procs create input chan create output chan for each node create a proc that: connects to node and set up a session creates proc for stdout creates proc for stderr waits on input chan for commands to send to the node stdout and stderr procs do: read from remote host write to output chan --- the aggregator part you want can be inserted between read the output chan and whatever you need to output to, but that logic doesn't exist in rx.c, i think :)
[9fans] just in case anyone has written this
before I write it. I need a command that concentrates one socket to many (outbound) and many to one (inbound) But it needs to do a bit more. On the inbound side, I need it to merge lines so that, e.g., a line from 11.1.1.1 and 11.1.1.2 if same, gets printed as 1-2: Mon may 8 2011 and if we have 11.1.1.1 and 11.1.1.2 and 11.1.1.4 and 11.1.1.5 you get 1-2,4-5: blah blah I have a sort of command like this, which I can adapt to Plan 9. If, however, someone already has this for Plan 9, it would save me time. For now I only need 64 hosts but at some point need 1024 (which my current command does) and eventually 262144. thanks ron
[9fans] New to the list and looking for an old plan9 book/cd
Hi all, Im new to the list. My interest in plan9 is to get it up and running on some of my NeXT boxes(stations, non-turbo). Things are a bit confusing for me when it comes to the current distro, but I do see a howto for an older plan9 release. I also found this post in the archives: http://9fans.net/archive/1999/03/28 So, I am looking for that kit(ISBN 003-017143-1), unless that release is available(freely and legally) online already(then I just need a link). But I wouldn't mind having the actual book. Thanks in advance for any help, and I hope I can get plan9 working on these slabs :)
Re: [9fans] New to the list and looking for an old plan9 book/cd
all that information is for the second edition. the third edition involved a pretty substantial set of internal changes. things were improved in almost every way, but one casualty was much of the platform support in the cpu/terminal kernel. in particular, we don't run on the NeXT boxes any more. we still have the relevant compiler, but i'm afraid getting the kernel working there would involve some pretty substantial kernel programming. the fourth (current) edition is updated regularly and is available for download from the web site. Vita Nuova sells CDs and printed manuals.

Re: [9fans] The Olde 2e 'worthies' ... ?
I happen to have the license in front of me, what do you want to know? I recall there was a registry of 2e license holders. For those of us wanting to swap code restricted by the old Labs 2e license, it was the way to determine if the proposed recipient was a valid license holder. Again, this is all a rather fuzzy memory ...
