Yes, I couldn't find any in my XCompose file and in the layout file.

I am not sure I understand this correctly.  I know that Kate is plain text

I tried thrice to send a reply to your previous message. Those messages are 
shown as being sent, but does not get delivered to me through debian list.
(Earlier, I got a message that there was a bounce and that I would be removed 
if it happens again. I don't know if I have been removed from the list or not.)
I want to repeat that my problem of .XCompose not working is not lmited to 
Indic scripts. It is happening with English too.
BTW, InScript is one layout among many layouts for the various Indian Scripts.

Network services fail on startup

[Ross Boylan]

I am having intermittent problems on startup in which network services do
not start properly, generally with messages suggesting the network
interface they need is not available. If I stop and start them after, they
will run.  I suspect this is a result of the interaction of systemd,
ifupdown, and a pre-up script that takes a while to execute.  But if I look
at things now it seems the dependencies in place should suffice.  Of
course, this is after I restarted it, and so perhaps the dependency is
added dynamically, too late to do any good.

I think what I need is for network-online.target not to be ready until
after the interfaces ifup controls are up, but I'm not sure how to do it.
Also not sure it's the problem, particularly since some information
indicates it already has such a dependency.

Details:

My main interface is controlled by /etc/network/interfaces that includes
allow-hotplug /enp*
iface enp5s0 inet static
   # etc

The interface has a pre-up script that has over 1,000 iptables add lines
for blacklists, and I suspect this is slowing things down enough to cause
trouble.  I was not having problems when the script was shorter.

This is a problem other have encountered:
https://unix.stackexchange.com/questions/209832/debian-systemd-network-online-target-not-working
https://unix.stackexchange.com/questions/257888/systemd-wait-for-network-interface-to-be-up-before-running-service

Various solutions are suggested, with a leading one being a dependency on
network-online.target.  But all my network services already have that
dependency.  For example,
# systemctl cat tftpd-hpa
# /run/systemd/generator.late/tftpd-hpa.service
# Automatically generated by systemd-sysv-generator

[Unit]
Documentation=man:systemd-sysv-generator(8)
SourcePath=/etc/init.d/tftpd-hpa
Description=LSB: HPA's tftp server
Before=multi-user.target
Before=multi-user.target
Before=multi-user.target
Before=graphical.target
After=remote-fs.target
After=network-online.target
Wants=network-online.target

tftpd-hpa is the service that fails most consistently.

# systemctl list-dependencies tftpd-hpa
Mon 13 Jul 2020 02:42:22 PM PDT
tftpd-hpa.service
● ├─system.slice
● ├─network-online.target
● │ ├─networking.service
● │ └─NetworkManager-wait-online.service
● └─sysinit.target
etc.
Notably absent from network-online.target's dependencies is anything
related to ifup.
However, ifup@enp5s0.service appears as an After dependency of
network-online.target when viewed another way:
# systemctl show network-online.target
Id=network-online.target
Names=network-online.target
Wants=NetworkManager-wait-online.service networking.service
WantedBy=tftpd-hpa.service nmbd.service hddtemp.service docker.service
mythtv-backend.service exim4.service hylafax.service smbd.service
inetd.service isc-dhcp-server.service

NetworkManager-wait-online.service
Documentation=man:systemd.special(7)
https://www.freedesktop.org/wiki/Software/systemd/NetworkTarget
Any suggestions?
Ideally I would not be tied to the interface name, so that if I plug the
network cable into another port things will still work.

Thanks.

Yes, apparently so. Sorry about that!


Based on a bit more digging, apparently calc does also have an atan()
function, which produces the arctangent of its argument; atan(1)*4 gives
3.14159265358979323848. Oddly, that last digit is not the same as what
'bc -l' gave from '4*a(1)' in Greg's demonstration; it looks like
atan(1) gives a value which is off in the very last displayed decimal
place from what Greg gave. I suspect that there is display rounding
involved on one side or the other.

atan() is of course more typing than a(), but it's also both arguably
more guessable (without already knowing function names) and definitely
more identifiable (in terms of recognizing what the function does from
the name), so there's a tradeoff.

It appears to use the argument as an integral factor of the answer
quoted. However, the last example seems wrong. The answer ought to be
3.14163, which is 34907 * 0.9. Was that a copy/paste failure?

So it looks like the argument's sign is ignored.

Perhaps it's connected with the facility you mentioned earlier,
the option to present non-integer output in the form of a ratio
of two integers.

That appears to be because it's not supposed to be possible to install
both of these two packages side-by-side.

They apparently both provide files that satisfy the same requirement,
such that having both of them present on the same running system
wouldn't make sense.

You'll need to narrow down your list of packages to be installed, by not
using the wildcard.

The list of package which that wildcard pattern would match can be
identified in a number of ways, but I just did it by the following:

$ apt-cache search foomatic | grep ^foomatic

(I'd expect 'apt-cache search ^foomatic' to do it, but apparently that
also matches the cups-filters package. I don't care enough to
investigate why at the moment.)

> How do I go about reporting this problem? w/o email on target Kali

I did write out a fairly lengthy, step-by-step answer to this, but I
think the answer had started to become condescending and generally
unproductive, so I'm not going to include it here.

The short answer is that when you cancel an otherwise-complete bug
report from the 'reportbug' program, it saves the result into a file,
and you can take that file to another machine and (with a little work)
turn it into an E-mail that can be sent from there.

I use a similar method on my own computer, since although I do have the
ability to send E-mail from here, I can't do it from the command line or
via reportbug. I suspect I don't have a working SMTP configuration
defined anywhere those mail systems know how to access.

(It turns out I got the specification of what the precision can be
expressed as wrong, and "precision" may not be the correct term for it
anyway; see below.)

I don't understand the full algorithm myself, but the output seems
coherent:

$ calc
C-style arbitrary precision calculator (version 2.12.7.2)
Calc is open software. For license details type:  help copyright
[Type "exit" to exit, or "help" for help.]

; pi(.5)
3
; pi(.1)
3.1
; pi(.9)
2.7
; pi(.05)
3.15
; pi(.0005)
3.1415
; pi(.5)
3.1416
; pi(.1)
3.14159
; pi(.9)
3.1416

I generally just use something like 'pi(.0001)' (i.e., hold
down the 0 key for a while in between . and 1), and that produces all
the precision I could really care for. The limit that gets printed (at
least with default configuration) appears to be

; pi(.0001)
~3.14159265358979323846

and you can get that same visible result with a much shorter precision
value. I expect that there are configuration settings which will
increase the displayed precision, but I've never needed to find them.

Also, it turns out that it accepts values >=1 and <=0 as well:

; pi(5)
5
; pi(10)
0
; pi(50)
0
; pi(3)
3
; pi(4)
4
; pi(2)
4
; pi(-1)
3
; pi(0)
zero epsilon value for pi

; pi(1)
3

The results just aren't very useful.

Yep - as soon as I saw someone point out what this flag did, I figured
this would be in there somewhere. (I didn't figure it out from looking
the flag up in the man page, but that's me.)

Definitely convenient, but also requires knowing more about math than
I've managed to internalize over the decades to figure out. I would not
have thought of multiplying by the arctangent of 1 (or of anything) to
arrive at pi.

In the past, on Debian/buster, I did this, not having encountered 
problems, but of course I cannot give you any warranty for your 
installation (! Note that my notes and experience is not for the most 
up-to-date version of cherrytree !):


1.) download the latest version of the required dependency which is no 
more in current stable or newer Debian repositories:

https://packages.debian.org/stretch/amd64/python-gtksourceview2/download

2.) download the cherrytree *.deb package:
https://www.giuspen.com/cherrytree/#downl

3.) install both packages with the following commands:
apt --no-install-recommends --no-install-suggests install 
./python-gtksourceview2_2.10.1-3_amd64.deb

apt install ./cherrytree_0.38.10-0_all.deb


Later on I moved to this solution, which I am currently running on 
Debian/testing: if you consider the usage of  flatpak  to be an option 
for you then could try it. Actually I recommend this over the first, 
above mentioned older solution.Keep in mind that using flatpak there 
will be install a "containerized, very well defined mini-linux 
environment" for you, which is then taken advantage of by the apps which 
you install (by a flatpak command) to run "inside" this flatpak base 
environment. The base flatpak installation and a first graphical app 
depending on Gtk, like cherrytree, will occupy some 2 GB of storage space.


1.) install  flatpak
apt install flatpak

2.) install cherrytree as an flatpak app; this will automatically 
install also all the by cherrytree needed flatpak base environment 
components

flatpak install flathub com.giuspen.cherrytree

3.) run and enjoy cherrytree
flatpak run com.giuspen.cherrytree

I am using cherrytree like this for a year now without having run into 
any trouble.



If your host desktop environment is Plasma (KDE) and not Gtk (GNOME) 
based, then you may want to consider to also add Debian package 
xdg-desktop-portal-kde  to your KDE Plasma installation from the usual 
Debian repository with the usual apt command, so that GTK apps can use 
KDE dialogs, and also flatpak apps can access native KDE dialogs. etc.
I finally have kept a note stating the following concerning the 
xdg-desktop-portal-kde addition, although I cannot explain anywmore why 
I made this and kept the note on it:
export GTK_USE_PORTAL=1	  add this to the end of your ~/.profile 
assuming your system doesn't use either ~/.bash_profile or ~/.bash_login.

Buenas tardes, respuesta ante brotes en la industria

[Alejandra Gaona Rojas]

Hola, buen día,

Te mando un cordial saludo deseando que estés muy bien.

Con la novedad que la semana pasada nos reincorporamos nuevamente a todas 
nuestras actividades y a esta “nueva normalidad” y decidimos hacerles exámenes 
de COVID-19 a la mitad de nuestro personal. Por instrucción de nuestro 
Director, se le pidió a todos nuestros colaboradores que si tenían algún tipo 
de síntoma o malestar no se presentaran a la planta y guardaran reposo en sus 
respectivas casas. Para los que sí se presentaron, iniciamos el día 1 
realizando 35 pruebas y afortunadamente no tuvimos ningún caso positivo, día 2 
realizamos 25 pruebas y tuvimos un resultado T1 (infección pasada con 
anticuerpos protectores más de 14 días), es decir se había presentado la 
enfermedad en el pasado y ya había generado anticuerpos, y en el día 3 
realizamos 15 pruebas y se tuvo un caso T2 positivo con apenas inicios de 
síntomas, se realizaron las medidas y los protocolos necesarios y se aisló a 
esta persona para su seguridad y la de sus compañeros. Esta semana vamos a 
estar 
 testeando a las demás personas que no se incorporaron en la primera semana con 
la finalidad de ir segmentando e incorporando poco a poco a todo nuestro 
personal. 

Estar detectando y aislando los posibles casos de COVID va a ser la única 
manera en que vamos a poder retomar nuestras operaciones de manera escalonada y 
segura. Actualmente estamos viviendo una etapa muy complicada en donde por lo 
menos conocemos a 1 persona que tuvo o tiene la enfermedad y no podemos evitar 
que la gente siga saliendo a la calle, pero lo que sí está en nuestras manos es 
tener controlada la situación dentro de la Organización evitando cualquier tipo 
de brote entre los empleados.

Te recomiendo estas pruebas que son las que nosotros utilizamos, cotizamos 
varias pero ninguna nos dio la confianza ni la seguridad hasta que finalmente 
dimos con estas que están autorizadas por COFEPRIS:

These are not helpful at all.
Please gather a few information

1) uid of postfix user
 id postfix

2) now stop and start postfix
systemctl stop postfix
systemctl start postfix

Are there any issues in the log?
journalctl _UID=

Same thing for the cases when it went down.
Do the logs show anything?

https://packages.debian.org/search?keywords=cherrytree tells me that
cherrytree is currently only available in the stretch (oldstable) and
jessie (oldoldstable) suites.

https://tracker.debian.org/pkg/cherrytree tells me that cherrytree was
removed from Debian in 2017, here is the removal report:
https://tracker.debian.org/news/864463/cherrytree-removed-from-testing/

Now, that removal report isn't terribly clear. The removal reason
appears to be "Bug #867787: cherrytree: Changes sometimes not saved".
#867787 was a grave bug against cherrytree which, presumably, was not
fixed in time for a release, so the package was dropped (in other words,
it wasn't being maintained).

However, there is hope for it to return in the future,
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=947338 also includes

And I assume they're not in the files that you wrote from scratch,
like .XCompose. Would that be right?

Kate appears to be a normal text editor. The third sentence of its
official description (https://kate-editor.org/) says "Choose it for
[…], editing configuration files". It doesn't seem to me to be
like writing text files in, say, Word (a word processor).

It would be nice not to get sidetracked by this, and to find out
whether the way that the Indic Script input system (InScript) works is
compatible with the composition of characters, which is the purpose of
.XCompose. (I'm assuming that linux tries to give the >1billion people
concerned an InScript system that's compatible with other platforms).

Cheers,
David.

That looks to me like damning with faint praise.

I would say that python2 should never be used as an interactive
calculator precisely because most people will be using literals
most of the time, rather than variables.

I googled .  The first result
didn't talk about them at all.  The second result was to a PDF which is
apparently their official documentation.
.

In it, there is a brief mention of some option you can toggle called
"Show Non-Printable Spaces", whose description is "Show/hide bounding
box around non-printable spaces."

I have no idea what they consider to be a "non-printable space".  You
could try it.

I meant use in your bash + grep command.  The earlier attempts to use
$'\x00A0' or $'\x00\xA0' were not correct.

Not really, the reason is that in Bullseye gcc now passes the
--as-needed option to the linker to reduce unnecessary linking of
libraries (and dependencies in the Debian package system).  According to
the binutils documentation,

,
| '--as-needed' causes a DT_NEEDED tag to only be emitted for a library

I use the gnome-calculator as it's installed with Gnome.  It even sports
a console version called gcalccmd.

I like that previous results are available in a scrollback window and
can be brought back to the entry box with a click.  Either the result or
the formula can be recalled.  It has several modes and I mostly use it
in Basic mode.

*BAM!* That's how I found galculator. Well, via the simplest part to
the left of the first pipe, anyway. I create my own themes out of
preexisting ones. ALL the keys become "invisible" on some of the other
calculators. I genuinely hate when that happens.

YES, it's fixable. There are some other "priorities" lined up in the
queue ahead of it... unfortunately. Just waiting on a delivery truck
this very second, actually.

Re: AMD FirePro - second monitor

[Jakob Miksch]

I am using the standard display config tool from GNOME.

In the meanwhile I figured out that the second monitor actually works on 
a lower resolution. I do not understand why. This "fix" is not ideal, 
but for my use case acceptable.


I connected my two monitors with a laptop that is also running Debian, 
there everything works without problem - also on the highest possible 
resolution.


Thanks though for your response.

Thanks for the suggestions.  I hate using the mouse so I'll skip the GUI
emulator... but orpie looks very interesting and could be quite useful
on my wee Gemini PDA in case I don't want to run Emacs.

I should say that, if I really want a proper calculator experience, I'll
pull out my HP-41C which is, incredibly, more than 40 years old and still
working!  It's the last calculator I bought.

I know you are looking for a GUI calculator app, however I would like to entice 
you with a CLI app that is easy to use, but will make your coworkers think you 
are secretly a computer expert. 
I tend to use python3 in the terminal window. I open a terminal, type python or 
python3 in the command line. It lets me do relatively complex calculations, and 
makes easy copy/paste of the entire calculation where required 
I use powershell in Windows the same way. Can just use the up-arrow to repeat 
similar calculations. 
Python is a programming language and it’s pretty simple to set up all kinds of 
repetitive math quite easily, but you probably won’t need all the capability 
(at least at first).
4/5 (enter) gets you 0 which is good for estimating 
but 4.0/5 gets you 0.8 like you probably expect

So I'm curious.  Since X is running before I log in, how does it know to
write the log file to my home directory?

And if this is a newer thing, it's puzzling that booting the newer
kernel causes X to write to /var/log while under the older kernel it
writes to my directory.

Yes, maxima and mathematica are similar in that they are both symbolic

This is correct.  The -l *also* sets the bc "scale" variable to 20,
meaning it calculates non-integer values to 20 decimal places.  Using
such a high precision is extremely important with certain calculations,
where using lower precision values would cause severe rounding errors,
which would accumulate and worsen quite dramatically.

unicorn:~$ echo 'e(1.4*l(500))' | bc -l
6005.62216990715616614180
unicorn:~$ echo 'scale=2; e(1.4*l(500))' | bc -l
5943.18

Never set a low scale value in bc.

If you don't want to see 20 digits after the decimal place, perform
rounding in a separate step.

unicorn:~$ printf '%.2f\n' "$(echo 'e(1.4*l(500))' | bc -l)"
6005.62

Check the time stamp on the Xorg.0.log file.  You are probably reading
the wrong one.

Since Debian 9, there are *two* possible locations for the Xorg.0.log
file:

/var/log/   (if X was executed with root privileges)
~/.local/share/xorg/(if X was executed without root privs)

Before Debian 9, X was always run with root privileges, through the
use of a setuid wrapper.  Nowadays, that is not typically the case,
but it still *can* be in certain setups.  So it behooves you to check
both places.

Note that tr does not handle multi-character sequences.  If you pass
something like

tr abc xyz

It does *not* look for "abc" sequences and convert only those sequences.
Rather, it looks at single characters.  It converts 'a' to 'x', and 'b'
to 'y', and 'c' to 'z'.

The number of characters in the first pattern is supposed to match the
number of characters in the second pattern, so that there is a 1:1
mapping.

GNU tr also does not handle multi-byte *characters* correctly (which
violates POSIX -- it's a known bug).

So, your tr command actually converts all c2 bytes into ! and all a0
bytes into ! as well.  Not *just* c2a0 pairs.

Nevertheless, this is useful as a first pass approximation to say that,
hey, there *might* be a bunch of NBSPs here, and you should take a
closer look.

NBSPs most often result when someone gets lazy and pastes a line from
a web page or from a Microsoft Word/Excel document into a Unix
terminal or X11 application, instead of pasting just the characters
they actually want.  Web pages, especially *older* web pages, often
use NBSPs for primitive formatting.

Bash's $'...' quoting allows several different forms, and you've used
the wrong one.  The \x is followed by *two* hex digits, to give a single
byte.  You've got $'\x00' which is a NUL byte.  Passing a NUL byte as
an argument to a command is equivalent to passing the empty string.

So, basically you have run

grep '' .XCompose

which, as you observed, gives you every line of the file.

I would imagine you were trying to pass a Unicode character.  If that's
the case, you need the \u or \U form instead.

grep $'\u00A0' .XCompose

Unicode character 00A0 is a non-breaking space.  It's not clear whether
that was your intention or not.

Uh... you mean you *weren't* trying to grep for non-breaking spaces
in your file using bash's $'...' quoting syntax?  You're just typing
something you found at random on the Internet without understanding
it?  That's pretty dangerous.

 might be good reading for you at
this point.

The two hex bytes c2 a0 are the UTF-8 encoding of a non-breaking space,
so it *does* seem like you're chasing after non-breaking spaces for
some reason

If that's truly your goal, you might also want to pursue configuring
your text editor to show them to you.  There are various ways to do
that, depending on which text editor you use.

(I don't even know whether you're in a UTF-8 encoding, though, so
who knows whether those are even the correct bytes for an NBSP in
your locale.  You're better off using \u00A0 instead.)

I'm using "bc -l" either.

"-l" is including the math lib, for functions like exp, sin, cos, etc.

"bc" can calculate with arbitrary precision length.

I used to have a simple alias for tcsh which just evaluated the command

since 2002 or so.

But still, with zsh I'm really doing the same thing, except in zsh it's
a combination of an alias and a function.

Most probably you're missing nothing. I picked up bc years ago because
it's a build dependency for the kernel. It solves my needs, and I happen
to remember pi up to 8 digits so the lack of pi() function is not an
issue to me.

On a side note, "calc" is 4 letters, and "bc" is two :)

What about calc (currently in the package of that name, formerly in the
package apcalc)? That being what I've used for over a decade now.

Reading through the bc man page, it looks to me as if using calc it
should take comparable numbers of keystrokes, aside from typing the name
of the program itself.

In some contexts it could even need fewer; for example, calc (as shipped
in Debian) provides the built-in function 'pi()', which takes a
precision - expressed as a value between zero and one - and returns pi
to that level of precision. The list of built-in functions in the bc man
page is very short, and doesn't include any such thing, so unless
something has added one without the man page getting updated anything
that needs to use pi is going to take more typing than with calc.

calc also has the option to present non-integer output in the form of a
ratio of two integers, which means you don't have to figure out manually
what fraction a given result is; at a skim, I don't see indication that
bc has comparable functionality.

I've heard recommendation of bc before, but to date I've yet to
encounter anything that makes it seem preferable over calc, and I'm
curious what I'm missing.

things.

Here is a sample session (I actually have `alias maxima=maxima -q`):

$ maxima -q

(%i1) a: 2;
(%o1)  2
(%i2) a**10;
(%o2)1024
(%i3) sqrt(%o2);
(%o3) 32
(%i4) sqrt(2);
(%o4)   sqrt(2)
(%i5) %o4, numer;
(%o5)  1.414213562373095

It is possible to write scripts and batch-process them which allows
integrating maxima with other (text-based) tools. There are also GUI
frontends, but I did not find them a large improvement over the commandline
for Maxima. I even made a script to auto-replace Maxima variables in LaTeX
files, but it is not available online yet.

For spreadsheets and on low-end computers where maxima does not run quickly,
I prefer `sc-im` which is unfortunately not in Debian:
https://github.com/andmarti1424/sc-im

In case anybody wants an unofficial Debian package, I hacked one together
here: https://github.com/m7a/lp-sc-im

There are plenty, for all tastes. Try "apt search calculator".

Galculator works for me, but I only do simple one-stage things with it.
If I need multi-stage, or repeated near-identical calculations, I use a
spreadsheet.

But I don't do many calculations, so if I used one of the command-line
options as most seem to do, I'd spend more time reading the man page
than actually calculating.

Chromium randomly crashes

[Toni Casueps]

Not sure if I should report this to Chromium or to Debian, but I guess that 
packaging a new Chromium version could fix the problem
I updated (on Debian 10) to 83.0.4103.116-1~deb10u2 and after some minutes it 
crashes giving this log. It's difficult to tell when it happens as it's really 
random, just reading a page and scrolling down, the window disappears and the 
process ends, it could be after 2, 5, 10 minutes... totally random:

if you want a simple gui calculator you might try xcalc from the package
x11-apps.

Try, in a command line, "apt search calculator". I get 127 hits (of
course not all of them are a calculator app. Let's say a rough third
is. That leaves fourty calculators to choose from!).

> What do you guys use? I'm having trouble with Galculator.

Ah. Now we're talking. Given that broad choice, you will get reams of
answers, depending on people's preferences and needs. Your approach
will depend a lot on how you do such things. Test a few or ten of the
above options. Ask people for their experiences. Things like that.

My favourite one won't be in the above list: it's Emacs calc.
Unlimited precision, symbolic math, units, stack, trail -- and
seamless integration with my favourite text editor.

Not that I use it often, but KCalc came as part of my KDE install.  Of
course, if KDE is not part of your install, it might need to pull in a
few dependencies.

There's also deepin-calculator.  which I've not even installed, never
mind try.
