There is actually a simple and obvious answer to that 
question: When sleep deprived I am a complete moron! :P

Seriously now, I was in fact a bit hasty and didn't do 
my homework carefully enough. The song goes like this:

* lightdm *Depends* on lightdm-gtk-greeter
* lightdm-gtk-greeter *Recommends* gnome-themes-standard
* gnome-themes-standard *Recommends* gnome-accessibility-themes

However, that's nothing serious. You should thus be able 
to uninstall gnome-accessibility-themes after installing 
lightdm without breaking anything.

Protip: If you'd like to avoid such unwanted installs, 
there is an easy way to tweak apt, namely by creating 
this file:

  $ cat /etc/apt/apt.conf.d/01norecommends 
  APT::Install-Recommends "0";
  APT::Install-Suggests "0";

Actually, that's usually one of the first things I do on 
a fresh De??an system. There is one potential drawback 
though: *Some* of the "Recommends" might actually be quite 
useful. In those cases you'd have to install them manually.

eheheh! "minimal" means "contains only the essential stuff in the
smallest possible amount of space". Hence you will find a console
interface, and a lot of console-based utilities, but no X. The lack of
X is also stated clearly in the webpage.

If you need a live with X, you can find one of those made available by
fsmithred and the refracta team.

 Indeed it does! I didn't even thought to try that. Looks like

Emacs is not trying to be a development environment; it always was one.

Emacs is an excellent user interface, development environment, and
desktop for ancient, text-only terminals.  That's what it was for back
in the day.  That's what it still is.

But people seem to be able to afford better terminals
these days.

For me, Emacs is a lot more than a development environment, though it's
good for that too. I've written whole books using Emacs as my editor, and
it's ability to handle unicode (and thus, foreign scripts) has been a
Godsend. I've mentioned a couple of times that I live in Taiwan, and Emacs
has great Chinese-input capabilities - superb for editing the html pages on
my bilingual website.

Kudos to all the folks who have worked on Emacs through the years.

For process supervision, try 'M-x proced', a "mode for displaying

in brief it means that is impossible to define the scope for a
function or variable. so if a function or variable has the same name
across the running instance, it will clash. one has in fact to use
prefixes or suffixes to distinguish. its quite self-defeating for
Emacs at this stage of development, but we can live with it.

I agree with Robert the multi-lang support is very important and very
well implemented in Emacs. Since many years all my work depends from
Emacs. I've had the chance to offer a dinner to RMS for my gratitude
for Emacs and I'll do that with any other Emacs developer I'll meet in
my life.

Now I wonder if the above will be repeated by someone with
s/Emacs/systemd/ in some future.  maybe its all relative and we are
all fanatics in the eyes of Vim users :^)))

The bidi algorithm does have serious problems in org-mode for
rendering paragraphs in documents with both normal right-to-left
languages of and the fashionable left-to-right ones. For example, a
Hebrew paragraph in an English org mode document renders in reverse
line order, ie. a three line paragraph will display text in the
correct direction but it will display:

   line 3
   line 2
   line 1

That's interesting: Just guessing in the dark (me, eh, not you capable
persons!) there might be also my problem with the logout (which happens
from time to time). Apparently, it looks like the logout does not get
to an X process resting blocked there. So, i tried your "exit 0".

Now, i wanted to ask - a probably very dumb question:

.xsessionrc or .xinitrc (what's difference? .xinitrc is used/needed to
do "startx" (i.e. start X without a login manager), correct? How otoh i
would make slim point to .xsessionrc ?

Just to try i edited both identically:
---
#!/bin/bash
xrdb -merge .Xresources
setxkbmap -option terminate:ctrl_alt_bksp
exec jwm 
exit 0
---

It seems to work for starting X via startx. For slim i would have to
change the login command this way:

login_cmd   exec /bin/bash -login ~/.xinitrc

?

@ Irrwahn: Your keyboard setting to have the forced break of an
xsession seems to not be respected though (?)

What am i doing wrong? Or, might there be an alternative to set that
keyboard command in the startup of JWM? I looked into the startup of my
old fluxbox/crunchbang desktop and there i have:


# Only run fbxkb when there are more than 1 available layouts
setxkbmap -query | grep "^layout:" | sed "s/^layout: *//" | \
grep -q "," && [ -x /usr/bin/fbxkb ] && fbxkb &


Would that be, ceteris paribus, transposable, in some way, to jwm
to have the Ctrl+Alt+Bksp... (?)

AIUI, OpenRC uses the same RC scripts as does SysV-RC. 

However, if _I_ were to tinker with that, I'd first try 
it in a virtual machine. The risks to end up with an 
unbootable system are IMHO to high to mess with a 
"production machine"[1][2]. Plus, VMs are much faster 
in rebooting, and much easier to restore to a working 
state (think snapshots).

[1] In the broadest sense of the term.

[2] Just because there is by now already a variety of 
preliminary Devuan live images (BTW, thanks aitor, fsr, 
KatolaZ, et al.!), is not necessarily a sound reason to 
test drive them as a recovery option for a botched up 
system.

I did'n have to do anything special in my installation. 
Just create-edited .xsessionrc, logged out and in again, 
that was it. So, beats me.

Works for me, except no .Xresources here, so I dropped that line.

Why would you have to? I'm getting more confused by the minute. :o

I don't even …. I simply fail to imagine what you might have 
done to your system to make it break so badly. Maybe something 
in your $HOME, pulled in from your previous installation, e.g. 
in your .Xresources? *Did you try it with an alternative, clean 
user account?*

Maybe unrelated, just mentioning it for the sake of completeness: 
xmodmap and setxkbmap don't play together nicely, cancelling 
out each others changes! (Anecdotal evidence, I cannot explain 
the real reason for this.)

Bottom line: I am totally at a loss. Sorry! :S

It means that any binding of some symbol is globally visible during the
dynamic lifetime of the scope which established it instead of being
restricted to code which is lexically contained in this scope.

Contrived example for that:

; function returning the current value of x + 1
;
(defun 1+x () (1+ x))
-> 1+x

; function which binds x to the value passed as argument and
; then invokes 1+x
;
(defun 1+v (v)
  (let
  ((x v))
(1+x)))
-> 1+v

; set x to 15
;
(setq x 15)
-> 15

; call 1+v with argument 4
;
(1+v 4)
-> 5

; call 1+x in the global environment
;
(1+x)
-> 16

This can be executed via *scratch* buffer which does Lisp evaluation
upon C-j. I've marked the lines showing return vaues with ->.

'Lexical scoping' (which works the way 'local variables' usually work in
other languages) didn't exist in the 'Lisp world' until Scheme came to
be.

[DNG] Request for Removal of slim package from Devuan

2016-05-24 Thread Irrwahn
To the Devs in charge, and to whom it may concern.

I just filed an issue against the Devuan slim package, 
requesting its removal from future Devuan releases. 

Full quote below signature.

Urban

Request for Removal of slim package from Devuan

I hereby request that the slim package, containing the SLiM 
Simple Login Manager, be removed from future releases of Devuan, 
at least from the Jessie and testing suites. It may have its place 
in unstable for the time being.

The reasoning that leads to this appeal is as follows:

1. It has no upstream. 
   The project has evidently been abandoned, the homepage was 
   taken off the web, leaving behind a stale github mirror that 
   as of today carries only a README file dated from 2016-04-12, 
   containing the following information, verbatim quote:
   "Note: This repository was used as backup source and is no 
   longer maintained." [1]
   
2. SLiM has various apparent issues, notably: 
  * not playing nice with X session managers
  * being unable to preserve the last chosen session between logins
  * it is a nuisance to provide user support for

3. It has already been removed from Debian testing and unstable (sic!).
   There is reason to suspect it would have been removed from Debian 8, 
   were it not for the early Jessie freeze on 2014-11-05.

4. The Devuan package appears orphaned, the code has not been touched 
   for about a year. Considering its upstream is no longer maintained 
   either, the package might impose a security risk not tenable for a 
   stable release.

Just to prevent possible misunderstandings, some 
clarification re my stance on that: 

I would never object to Devuan becoming the new upstream 
for SLiM!  IMO it would be nice to have a lightweight 
graphical login manger available, especially for low 
end hardware.

However, until somebody steps up and fixes the obvious 
errors I propose to let it reside solely in unstable. 
*If* it gets eventually fixed, it can go down the 
designated path of being allowed to enter testing, and 
eventually stable, once testing becomes the new stable.

BTW, fun fact, these are the versions of slim currently 
in the Devuan repos:

testing:  1.3.6-5+devuan1
stable, unstable: 1.3.6-5+devuan3

Anybody else notice something odd?  }:-P

So does for me now; there was a typo in ~/.xsession.rc :-(

I changed the cmd_login line in slim to be sure it loads correctly all
i want. If i execute the standard login_cmd without cycling thru the
sessions options, no desktop is started at (but i want charge you to
try something with slim - i saw your request ;).

BUT: Just to learn something what would be the difference
between .xinitrc and .xsessionrc?

In the standard login command (for linux)
login_cmd   exec /bin/bash -login /etc/X11/Xsession %session
%session is referred to what? The session chosen (by F1)?

And, do i read correctly /etc/X11/Xsession, that it automatically
integrates ~/.Xresources and ~/.xsessionrc ? So, there will be no need
to merge .Xresources in .xsessionrc ... (?) - differently from .xinitrc
which starts X without using /etc/X11/Xsession.

Thanks a lot in advance for our patience!

You are referring to /etc/slim.conf here. And yes, I assume(!) 
%session gets substituted with your selection from the F1 menu.

I think pages like e.g. http://unix.stackexchange.com/questions/281858/ 
explain it better than I can, but I'll have a go at it anyway:

Your ~/.xinitrc is executed by xinit when you use startx to bring 
up the X server. It is only used for that purpose, and ignored 
when starting X via a login manager. In fact, you can launch 
a session manager from within .xinitrc. Note: if there is no .xinitrc, 
in Debian startx invokes the default Xsession scripts, effectively 
doing the same as a graphical login would do, including sourcing 
.xsessionrc (see below). (On my desktop I do not have .initrc, but 
have .Xresources and .xsessionrc. No matter if I use startx or 
lightdm, I basically get the same X environment.)

Your ~/.xsessionrc is sourced by the script 
/etc/X11/Xsession.d/40x11-common_xsessionrc 
(using the $USERXSESSIONRC variable set in /etc/X11/Xsession). 

Your ~/.Xresources is sourced by the script 
/etc/X11/Xsession.d/30x11-common_xresources 
(using the $USRRESOURCES variable set in /etc/X11/Xsession). 

So, yes, your analysis is dead on. Matter of fact, you don't need 
*any* of .xinit, .Xresources or .xsessionrc, *unless* you need to 
perform some fancy extra configuration/initialization (like for 
the X  server kill hotkey, etc.). IOW: You can boot into X with 
an completely empty home directory! 

Note 1: .xsessionrc is a "debianism", not necessarily present in 
other distributions.

Note 2: There are even more hooks into the X startup sequence, as 
explained in the article linked above.

> Thanks a lot in advance for our patience!

Again, you're welcome. I even learned a bit myself over the course 
of the past few days, so ... yeah. :)

There is an editor written as part of the Racket version of Scheme.

Note: This example describes dynamic scoping.  The call to (1+x) uses 
the x that's active where it is called, not where it is defined.  
In lexical scoping, it would always use the x where it is defined, no 
matter what extraneous x's are around where it is called.

Not quite.  In Lisp 1.5 way back in the 60's they realised absence of 
lexical scope was a problem, and invented a wrapper called FUNCTION that 
you placed around a lambda expression that would make the enclosed lamda 
expression lexically scoped.  But Scheme decided that the extra syntax 
was stupid and implemented lambda expressions lexically from the start.

The example was supposed to show dynamic scoping but that's something
subtly different from what you're writing about. In the example above,
the 1+x function does a computation involving a free variable named
x. The 1+v functions binds the symbol x to the value passed as
argument. Because elisp (up to version 24.1) - as all mainstream
variants (whether or not the term 'mainstream lisp variant' make much
sense could be discussed) prior to Common Lisp - does dynamic scoping,
this binding is visible to all code executed while it is 'alive' at run
time, that is (in absence of multi-threading) all code textually
contained in the body of the expression which established the binding
and all function called from this code, functions called from functions
called from this code and so on. Hence, the 1+x call sees the binding
established by 1+v and returns the intended result despite there's also
a "global" value of x (15). In Common Lisp, the value bound to x by 1+v
wouldn't be visible to 1+x unless x was declared special.

What you're referring to ...

... and what the Lisp 1.5 FUNCTION was about was to enable solving the
so-called 'upward funarg problem': Assuming a function is returned
(passed upward) when evaluating an expression and later activated in a
different context, what are free variables used by the returned function
supposed to refer to, the values they had at the time when the function
was defined or the values they had when the function is activated? Eg,
assuming this code,


(setq seq-2 (let
((cur 2)) 
  (lambda () (setq cur (1+ cur)

(let ((cur 15))
  (dotimes (x 10) (print (funcall seq-2
-

should this print the numbers 3 - 12 or 16 - 25? The former happens with
Common Lisp, the latter with elisp. Lisp 1.5 supported either behaviour
despite it didn't do lexical scoping (FUNCTION was supposed to request
the first alternative).

What is the most recent update, besides the README?
Okay, I checked the referred link, Sep. 30, 2013.
Probably there are other, better maintained window managers.
A list of Devuan preferred WMs may be better than simply
removing this one.

Not strong arguments, in my opinion. 

* Not everyone uses X session managers.
* Most window manager logins do not offer out-of-the-box for
  maintaining previous session details.
* OPs posted difficulties may not inconvenience all users

We can suppose that isn't much research to find and exploit buffer overruns

Thank you for your input, Joel.

I would never have beaten the drum, if it was just any 
old application to be run by a user. But a login manager 
is IMNSHO a different kettle of fish. While not exactly 
at the heart of an OS (like e.g. the init system), it is 
nonetheless usually run under the root account, and is 
the first point of user interaction after starting up 
the system.

In my humble opinion a quality distribution like Devuan 
should not show a potential weakness at such a crucial 
spot by shipping a package in questionable condition. 

I admit freely I took action in such a drastic form in 
the hope to attract the attention of potential future 
maintainers willing to take over the task of saving the 
package from falling into total oblivion. The gear that 
squeaks the loudest ... you know the saying.

It's not a matter of .Xresources, but instead of the alias associated
to ls. If you type:

  $ ls -p

all directories will have a trailing "/", so you can set a proper
alias to ls in your .bashrc, such as:

  alias ls='ls --color=auto -p'

and you will have colours and trailing slashes. If you want all the
set of trailing characters to be used (i.e., * for executables, @ for
symlinks, etc.) you can instead use:

  alias ls='ls --color=auto -F'

You are right, i' try to fix this issue today. In Gnuinos i always 
include:


d-i passwd/root-login boolean false

in the preseed.cfg file, because i use to leave the root password blank.

Thanks your raising it :)

I solved this issue hacking "users-setup-udeb".

Shortly i will rebuild the installers :)

And by wrapping FUNCTION around every lambda-expression (which I did in 
those days) you oachieve lexical scoping.  But it's messy, and there's 
no defense against accidentally leaving FUNCTION out.

It would be fun for Devuan to become the upstream source for a Debian package.

Re: [DNG] Evince

2016-05-24 Thread Daniel Reurich
Hi,

Sorry for hooking back an earlier part of this thread, but I turned back
to xpdf a while back as it was the only pdf viewer that I found produces
consistently good and correct rendering results. It can print too. The
biggest problem is it is way too ugly. If we could wrap a nicer
interface around it, then I think it would be a master stroke.

Regards,
Daniel.

yep, that kept me stuck with evince all this time and until now. hence

viewer that can't print. Else I'd just use Emacs for that too ;^)

At least as safe as a package, both are taking executable content from
a source you don't implicitly trust and running it as root.  (The
install video shows a normal user but it assumes that user can run
sudo.  Look at the source.)  Now if it were a http url there would at
least be an argument about Man in the Middle threat, but it is an
https.  All they are doing is making a single cut/paste job to install
instead of a list of command most newbs will screw up and then flood
the forums about.

Hi emninger

pulseaudio is a layer on top of alsa, and no it's not necessary
