Re: Printing hebrew with mozilla
On linux mailing lists you would have a much better chance of getting a reply if you avoid the html mail (don't know about the policy on this list but on most lists its considered offensive). Most (all?) text mail agents don't handle html mails natively and even when I used graphical ones I disabled it for security reasons. I have no idea what you wrote, but guessing from the title you can try using xprint (the version from xprint.org). Worked for me last time I bothered with it. Otherwise there are some scripts that fix the font data in the postscript file.

Mozilla Printing
Sorry for mailing this mail in HTML! When I am running Mozilla 1.3.1 or 1.4.0 on my Mandrake-9.2 or RH 9-Enterprise WS Partitions, I can print Hebrew pages on any one of my CUPS configured printers, selected from the Mozilla printer selection window: LocalHP930C@:33 [HP930C connected to parallel port 0] SMB-Printer@:33 [HP930C connected to a win95 PC via samba] Tp0@:33 [Hp9330C local, configured with TurboPrint-free] When I run, mozilla 1.4.0 or 1.4.1 on Fedora-core1 or Knoppix 3.3 with added Debian applications partitions, all I can see in the mozilla printer selection window, is: "PostScript/default" , and the printers output only English. This happens when the printers configuration is the same as on mandrake 9.2. Konqueror, anyway, is printing Hebrew on all partitions, with any of the 3 printers.

persist + maxfail 0 works fine. Whenever there was a problem, persist +
maxfail 0 did their job and tried to reconnect again and again. Calling
the support desks of either Bezeq or Actcom revealed that at least one
of them is having problems. Yet currently I am only at test9.

There is little danger that the system won't boot any longer - the old kernel stays there.

OK, here is *really* what it is ;-)
RSS (resident set size) is the amount of memory mapped in RAM, per
process. There may be unmapped pages, but that is often the first
stage of swapping the page away or discarding it altogether, so this
is not as bad as it sounds.
Neither SIZE nor RSS fields count the page tables or the task_struct
of the process: those occupy at least 12K of memory that is always
resident. SIZE is the virtual size of the process (code+data+stack).
If you are really interested, go to your resident (pun intended)
kernel source tree. The header include/linux/sched.h defines
task_struct and mm_struct that contain the relevant per-process
info. Look at struct task-struct, it contains
struct mm_struct *mm;
and that, in turn, contains
unsigned long rss, total_vm, locked_vm;
Now look at the /proc interface to the per-process memory usage:
/proc//status. Here is my bash:
$ ps
PID TTY TIME CMD
2678 pts/300:00:00 bash
2689 pts/300:00:00 ps
$ egrep "^Vm" /proc/2678/status

VmExe: 508 kB
VmLib: 1444 kB
This is more detailed than ps or top. VmData is the heap. VmStk is the
stack. VmExe is the statically linked stuff. VmLib is shared
libraries.
All this comes from a function called task_mem() from fs/proc/array.c.
Vm{Size,Lck,RSS} come directly from task_struct->mm as explained
above. Vm{Data,Stk,Exe,Lib} are obtained by traversing the process
vmas that have all the details as flags.
Hope it helps,

I am the one who suggested it, and it seems to work very well for
me too.
But recently (over the last week) I noticed twice that my ADSL link
was flaky at best, and "poff"/"pon" (it's a Debian) solved the problem.
It might be related to my switch to 2.6test11 (which I did about a month
ago, when test9 or so came out), as it ("persist + maxfail 0") worked
for me for months with 2.4.2x before that, or maybe it's just that
Actcom are having a bad week?
So I'm following those primitive ping-based monitores to enhance
the reliability of my link too.
Is anyone aware of issues with ADSL on 2.6test?

Re: ADSL Monitoring Crontab
Hello,
I'm taking another approach: I have a process running, which makes sure
the connection is up every minute. The advantage is that if I don't want
ADSL connection for a while, I can kill a process, not crond.
This script has terrible bash syntax, but it has proven to work well for
over a couple of years, including those days when the connection went
down a few times a day. Only my username has been changed.

I am not sure. Some programs I measured did not exhibit any speedup by using /lib/i686. Apparently (but this is just a guess because I unfortunately did not have the time to follow this up) there is a specific library call or several specific library calls that are extraordinary slow in the tls library, and this slows down programs that use them, but doesn't affect programs which only use these functions rarely. Also, I'm guessing that TLS (thread local storage, NOT transport layer security) is not utter garbage, and is used for *something* - maybe it actually speeds up, not slows down, certain types of programs - presumably programs which use threads in some manner (don't ask me how or why...). > And another question, for the uninitiated (that's me) -- when I try to > output $LD_LIBRARY_PATH I get nothing.

Unfortunately, this doesn't tell the whole story, because the tls, i686, i386 variant directory don't appear them.
