Entre temps, j'ai encore pu faire évoluer ce tutoriel, pour Redmine et RVM.
Je pense que c'est un tutoriel très efficace, et, complet :
https://wiki.visionduweb.fr/index.php?title=Installer_Redmine_sur_Debian_avec_RVM

Ceci est un appel à tout relecteur qui voudrait participer au wiki de
Debian.
Je l'ai ajouté sur le wiki de Debian, mais, je n'ai pas pris le temps de
baliser le code ce qui n'est pas très lisible.
https://wiki.debian.org/Redmine#Installer_RVM_pour_installer_et_utiliser_Redmine

Concernant Docker, c'est plutôt de l'humour sarcastique car je suis bien
conscient que l'outil Docker est puissant, mais, je ne pense pas me
tromper en disant qu'il prend du temps, pour l'assimiler et l'utiliser
correctement.
Christian, si tu te sent le courage, l'envie, et, que tu aurais la

How about watching your movies with an in principle 3-line script:

set the presentation mode
run the movie
revert to non-presentation mode

My experience with automounters is that if you unmount / eject manually, 
it won't auto remount until you unplug and replug the drive. So from the 
file manager, select the mount point and from the right click menu 
select 'unmount', 'eject', 'safely remove', or whatever your file 
manager calls it, and then you should be able to mount it manually (from 
a terminal) wherever you want it.

Je te trouve bien sévère avec Docker. On peut bien sûr s'en passer
mais ça présente pas mal d'avantages. Je l'utilise depuis 2 ans et ça
fonctionne très bien sous Debian. Si le fournisseur de l'image (redmine
pour ce qui nous concerne) te fournit en plus le fichier de config pour
assurer le lancement, la mise en œuvre est vraiment très rapide.

Je n'ai pas remarqué de problèmes de performances.

Je n'ai pas de tutoriel prêt à l'emploi mais je peux regarder ça. Pour
répondre rapidement aux 3 points :
1. le déploiement est complètement décrit par un ou 2 fichiers de
configuration (Dockerfile et docker-compose.yml)
2. la sauvegarde se limite à la sauvegarde de la base de données
(mysqldump). Toute l'appli est décrite dans les fichiers de config, qui
permettent de la remettre en place si nécessaire et elle n'a donc pas
besoin d'être sauvegardée.
3. La migration des données d'une ancienne version de Redmine vers une
plus récente est identique à ce que tu as dû faire directement sous
Debian. Il suffit d'entrer dans le conteneur Docker de Redmine et
d'appliquer les migrations Ruby on Rails. 

On peut poursuivre cette discussion mais peut-être hors de la liste, le
sujet se concentrant plus sur Redmine et Docker.

So you hope for approximation of programming languages to a situation
where they enforce correct semantics ?
Well, my conclusion from model theory and Goedel was that you can either
have it certain or interesting, not both.

I became the C type of a programmer. Implementing straight ahead. Always
trusting the ability to solve the detail problems. Bad hair days included.
gdb and valgrind are my friends.

I cannot see much clarity of expression in Lisp or C++. Java seemed better
until i got in contact with the spaghetti inheritence of its class libraries.
In general i object the idea of separating model from implementation and
then hiding the latter.


John Hasler wrote:

The liar paradox is not sound. It demonstrates the fundamental risk
that a fine looking syntactical contraption turns out to be utter nonsense
with undefined consequences. (What Goedel did was to link that kind of
paradox to the properties of natural numbers and to math being performable
by countable many finite sentences composed from a countable alphabet.
So if you want numbers and math books, you also get Epimenides, the most
credible of all cretians.)


Have a nice day :)

The reason I wrote the comment above in square brackets was because it
referred to the [•], also in square brackets, rather than the thread,
and not because of your writing "… even secretaries …" in the anecdote.

Sure. But I haven't seen the article in question and what it claims.
Perhaps it indeed shows that they metamorphosed into fully-fledged
programmers without so much as a course or text. If it does, then
it undermines the case of those who write "learning emacs means
learning lisp" as a reason not to learn emacs.

Secretaries do amazing things given the right tools, or after finding
them, or without them. The amazement is of course in the eye of the
beholder, or the writer of articles, or anecdotes. They just *do*
things, like the rest of us.

Thomas, Guten Morgen.
That is correct in the correct context/Das ist ja richtig, aber im

I used the phrase "collapses to". I shunned the word "attains".
Does that make sense? <> statt << Zusammenbruch >>.
In other words, a process not an achievement.

Yet at the very least Aristotle began the development of modal and temporal
logics. This is well recognized today. From the beginning of classical
formal logic,
there also began the development of "non-classical" logics :-) The
automation of
logics of belief and contingency is underway for some time.
This is particularly strong in the Chicago area due to Argonne National
Laboratory in the southwestern suburbs, where Robinson worked after his
PhD. Also Overbeek, Wos, Winker (who I knew at uni), usw.

Re: Xfce Power Manger and watching movies full screen

[Georgios]

Thanks for your reply.
I already took a look at Caffeine before I send my first email.
The problem with it is that it looks for an app running so I do not
think its a good idea.
I often leave my laptop with a lot of firefox tabs open and expect it to
go to sleep mode or hibernation instead of closing it.

I will probably have to settle with manually checking presentation mode
although i was hopping for a more automated solution.

Running it without --now works but it still doesn't survive a reboot.

Executing /usr/sbin/update-rc.d rpcbind defaults

Well, that's how you do it, presumably, with xfce power manager, which
was the question. Obviously, you toggle presentation mode on and off as
necessary, unless you're watching netflix 24/7, which might curdle your
brain.

If not, there's 'caffeine'.

 Caffeine prevents the desktop from becoming idle when an application

 supplies a manual toggle, and the command ‘caffeinate’ can be used
 to prevent idleness for the duration of any command.

This exhausts my extensive knowledge in the area.

I'm pleasantly surprised to hear that worked. I wouldn't have said it 
was a given that an iPhone personal hotspot would do routing between 
multiple WiFi devices connected to it. Obviously between the WiFi and 
the phone, but...

Of course the downside of this approach is the iPhone itself switches 
away from WiFi when you do this, and any data usage *it* does while you 
are working goes over the phone, potentially costing you money... I once 
ran up a >$2000 phone bill while roaming in HK because I didn't realise 
an online broker's app was still running on the phone, streaming 
prices...

Hmm, interesting idea, but the situation I was previously in pertained 
over a period since Stretch became Stable until shortly before my 
original mail in this thread (sometime in February if I recall 
correctly). Over, naturally, multiple reboots.

For that period, I had to use sudo when issuing the pactl command (in 
Jessie and previously, the pactl command wasn't necessary at all).

So I guess I could have had some sort of configuration which repeatedly 
put me in that situation on every reboot, and the update that "created 
the problem" actually fixed whatever *that* problem was... otherwise, no 
I don't think so.

Thanks for the suggestion though

No problem at all - I have not done research recently - I stopped dealing
with this 12y ago gave up finally 10y ago. What I mean is I have not heard
anything significant, but the reading you point out looks interesting -
will follow up later.

I had a state of the art theoretical model - approved by two universities,
but for lack of funding I gave all this crap up. might someone else dig
further. This is best example how ignorance kills science.
Lets hope someone else goes the way to the end ... like Copernicus, Bruno

Чому Debian не рекомендує встановлювати primary_hostname (exim) власноруч?

[Yuri Kanivetsky]

Усім привіт.

То лист undead чи half-life? :)
https://lists.debian.org/debian-user-ukrainian/2006/11/msg1.html
Краще спробую поставити питання...

Нещодавно натрапив на сторінку в Debian Wiki

https://wiki.debian.org/PkgExim4UserFAQ#How_does_exim_find_out_its_host_name_to_use_in_HELO.2FEHLO.3F

де кажуть про те, що власноруч primary_hostname встановлювати на слід:

> Please refrain from using primary_hostname unless you cannot avoid using it. 
> It enhances the complexity of your configuration and leads to error issues 
> that are a hell to debug.

В принципі я можу припустити, що вони мають на увазі що міняючи домен
з якого відправляється пошта (From), треба буде не забути поміняти
primary_hostname. Але це начебто може максимум вплинути на те, чи
листи будуть роспізнані як спам (SpamAssassin score). І то не факт. Чи
є якісь додаткові міркування?

Далі, припустимо що я даю exim можливість визначити primary_hostname.
Для цього я мушу або покласти FQDN у /etc/hostname, або у /etc/hosts:

127.0.0.1  myhostname.example.com  myhostname  localhost

Першого варіанту хотілося б уникнути, занадто довгий hostname. Та й
начебто hostname має бути першим сегментом FQDN. Другий варіант майже
ідеальний:

$ hostname
myhostname
$ hostname -d
example.com
$ hostname --fqdn

Yes, to think of all the time wasted by so-called web designers
when all I do with a page like that is press Ctrl-A Ctrl-C and
paste it all into an emacs buffer with Shft-Insert. That way,
I get to read it in *my* choice of font etc.

If the page looks interesting and worth keeping, then I press
Shft-Ctrl-% ! which doubles every Newline, and Escape  Ctrl-Home
which then runs fill-region on every paragraph before saving it.
(These last two are the results of my "programming" ability in this
over-blown editor, ie my ability to cut and paste other people's
scraps. AFAIK no one, least of all User Services, was hurt in the
production of this code.)

Cheers,
David.

Si une erreur 400 ou 404 peut se produire, c'est que le navigateur est

Hi!
First of all thanks for the fast reply.

Yes I have presentation mode. I didn't even try it to see if its working
with hibernate. The problem with that is that its inconvenient to check
it and uncheck it all the time.

I will inevitably forget it sooner or later.

If you mean that, provided that the semantic of the elements is
univocal -and it is-, a correctly spelt sentence that you read as
"true" is "true", yes.

Or better, an elegant piece of code that you feel is correct when you
create it, very rarely fails, on the other hand code you struggle to
write can be weak.

The problem is that when the language itself is not elegant, it is
difficult to attain such elegance. But elegance is not bound to a
single language, it belongs to languages whose design is sound.

This view is outdated since nearly 90 years. The attempt to create a
language where semantical correctness results from syntactical correctness
was killed by Goedel's incompleteness theorem.

The insight was not new then. Paul the Apostle wrote about Epimenides:
"One of themselves, even a prophet of their own, said, the Cretians are
 alway liars, evil beasts, slow bellies."

In other words, lisp and prolog (and clojure and guile and scheme) give

I think that the original tale referred to their secretaries, and no,
it was never meant to be derogatory, anyone who understand what
happens around in the workplace KNOWS how fundamental is their
co-operation.

I also think that that was an example of "people who thought it whould
have been impossible for them to write even the easiest program". As
an example, my mother -yes she was a secretary- had her typewriter
replaced by one of those "videotyping" (I am translating the
"videoscrittura" term used then in Italy) in the early nineties. Those
were PCs within a typewriter, I suppose my mom received some sort of
CP/M with a word processor in a rom. It was very like a "tv
typewriter".

O.K., that was a typewriter, a tool she felt confident, so just asked
me a little help. But it had command sequences that were more user
unfriendly than mainframe commands. But, it was a typewriter, she had
no problem to use it.

(later "videoscrittura" machies from Olivetti were indeed DOS-PC in a
typewriter case, I saw people play Arkanoid with them)

Some ten years later, "videoscrittura" sets where completly replaced by
general purpose PCs with [you can guess the software suite].

But those were "computers" not "typewriters", and my mother feared
them, she wrongly feels herself unfit for those machines. I think that
having such persons create some sort of automation whould avoid
"scaring" words, not because "they can't" but because they wrongly
think "they can't".

Perhaps you are more successful with wcheck-mode which has more like

I really can't understand your attitude here.

Just kidding.

Don't you have a "Presentation Mode" checkbox somewhere in your xfce
power manager settings (or right-clicking an icon somewhere or something)?

Or maybe

 xfconf-query -c xfce4-power-manager -p /xfce4-power-manager/presentation-mode 
-T

I actually don't have xfce power manager here, so this is all completely
theoretical.

Or are you already in presentation mode, and something else is intervening?

FAQ: Jessie

[Dan Ritter]

There have been a lot of questions about jessie,
jessie-backports and jessie-updates.

Answers are here:
https://www.lucas-nussbaum.net/blog/?p=947


Summary from the end:


The jessie-backports suite was archived on archive.debian.org,
so you can use:

deb http://archive.debian.org/debian/ jessie-backports main contrib non-free

deb-src http://archive.debian.org/debian/ jessie-backports main contrib non-free

But then you will run into another issue:

E: Release file for
http://archive.debian.org/debian/dists/jessie-backports/InRelease
is expired (invalid since 36d 1h 9min 51s). Updates for this
repository will not be applied.

Unfortunately, with the APT version in jessie, this cannot be
ignored on a per source basis (it can with the APT version from
stretch, using the deb [check-valid-until=no] ... syntax). So
you need to disable this check globally, using:

echo 'Acquire::Check-Valid-Until no;' > 
/etc/apt/apt.conf.d/99no-check-valid-until

After that, apt-get update just works.

Re: Question about jessie

[Pierre Fourès]

Hello,

I have been wondering about the same question in the latest days and
here is some of the gathering.

The jessie-backports are deprecated since July 2018 as stated in this
message [1]. They are not part of the LTS, as stated in [2] in section
« Deprecation of LTS support for backports ». Thus, they are not
updated since July 2018. This has to be taken in consideration as no
security updates will be provided to theses packages. LTS is for the
vanilla Jessie.

The repository jessie-updates/ is of no use while in the LTS. All
changes has been merged in Jessie's point-release 8.11. But mind you,
I personally didn't understood well the meaning of jessie-updates (in
combinaison with jessie-proposed-updates). I formulated my new
understanding in [3] and Adam confirmed it in [4].

You can read the discussions about all that mainly in theses three
threads [5] [6] [7]. This will provide you more information about the
situation.

Pierre.

Xfce Power Manger and watching movies full screen

[Georgios]

Hi there!

I'm running debian testing buster and I'm using xfce power manager.
In xfce power manager settings on "System" tab I activate "hibernate" on
30 minutes and on the "Display" tab "Put to sleep" after 9 minutes and
"Switch off after" 10 minutes.

When i watch videos on netflix (full screen) the display doesn't Switch
off in 10 minutes but the computer hibernate at 30 minutes.

I do not want my laptop to transits on hibernate if I'm watching videos
full screen.

I'm running debian buster with firefox-esr browser and xfce4.

Thanks in advance for your help.

Because you cannot boot from GPT drive unless you have:

And, unlike its Solaris counterpart, ZOL's /sbin/zpool does not label disk by

Let me add 2 cents.

First: http://www.paulgraham.com/lisp.html

Second, for a bit of fun: http://www.paulgraham.com/lisp.html

My personal experience:

Would I like to hang out with lisp hackers? Definitely yes.

Can I? I feat the answer is definitely not. In my company (you can
guess it from the address domain), I know only another guy who knows
Clojure, and he's better than me… But we can't use it on our work.

Java, Java, Java, some SQL, more Java. If you are lucky some Scala.

Lisp is my lifeboat that saves the day and my brain when nice projects
come up like "make GDPR compliant this bunch of legacy applications",
situations where you have potentially tons of stupid, mechanical
editing. Yet Lisp gave me something useful on my work, and that is not
just being used to functional programming, but also being ready to
accept that "Ok, guys, here is a place where you have to start
thinking _very_ differently from where you were used to"; and
understanding why elegance is so good in coding: a piece of elegant
code is a piece of code that you actually "feel" is good code, its
correctness being almos blatant :).

This would be a great read, if 90% of the text wasn't 90% white. What the 
hell is wrong with good old black text?

That said, mention lisp and I think of the Amiga's where the preferred 
scripting language was lisp. And it was fast. But I never got hugely 
productive in it, bash was easier to bang up something quick and dirty 
to get the job done, or better yet, ARexx.  Compiled ARexx was also very 
fast, we wrote WDTV-5's first web page in ARexx, long before php and 
apache were  written to do much of that in a std format on linux. Circa 
1996 IIRC.  ARexx had hooks into every OS call, so unlike REXX or 
Regina, both of which isolated you from the OS, there wasn't anything 
you couldn't do with ARexx. The only REAL cron ever written for the 
Amiga was ezcron, compiled, it ran on about .001% of the CPU. And Jim 
and I wrote it in ARexx.

Erm, this guide walks you through the process of getting / root on ZFS,

I've followed this guide myself for an encrypted ZFS setup on Debian

Yes, I know. In 2.2 is mentioned to partition disks. And in 2.3 ZFS pool is created from partitions, not using full disks. And this is confusing me. 
Why create additional partitions not managed by ZFS?

Do your reading before spewing nonsense:

  https://leanpub.com/lisphackers/read

(and this is /only/ Common Lisp. There's Racket, Guile and the new
kid on the block, Clojure, each one with its own, quite interesting
projects -- check out Guix for Guile's current hot-spot).

Sorry, that sounds harsh, but that's how fake news are born. You've got
the tendency to state things as if they were true: then you've got the
damned duty to do some research before.

Furrfu.

I think also, but no one uses it except for emacs or some niche programming.
Do not understand me wrong - I think it is a pity that it is not used more
widely, but ... this is also my point. Few years ago I did some research
where Prolog is used ... guess what - very limitted domains. Perhaps you do
a research where lisp is used and share results.

This bug looks kind of similar (maybe unrelated to your problem).
There's a little fix (patch) from Eli Zaretskii.

This bug seems to bite me.  Emacs does not seem to get the dictionaries.
If I have aspell as  an installed package it seems to use it despite my
configuration :

;;-- Spelling --
  (with-eval-after-load "ispell"
(setq ispell-program-name (executable-find "hunspell")
  ispell-skip-html t
  ispell-local-dictionary-alist
  '(
("en_ZA" "[[:alpha:]]" "[^[:alpha:]]" "[']"
 nil ("-d" "en_ZA") nil utf-8)
("af_ZA" "[[:alpha:]]" "[^[:alpha:]]" "[']"
 nil ("-d" "af_ZA") nil utf-8)
("nl_NL" "[[:alpha:]]" "[^[:alpha:]]" "[']"
 nil ("-d" "nl_NL") nil utf-8)
  ("de_DE" "[[:alpha:]]" "[^[:alpha:]]" "[-]"
 nil ("-d" "de_DE") nil utf-8),
  ("af_ZA,en_ZA" "[[:alpha:]]" "[^[:alpha:]]" "[']"
 nil ("-d" "af_ZA,en_ZA") nil utf-8)
)
ispell-dictionary "af_ZA,en_ZA"))

Emacs complains about the last line:
Debugger entered--Lisp error: (error "No data for dictionary
\"en_ZA,af_ZA\" in ‘ispell-local-dictionary-alist’ or
‘ispell-dictionary-alist’")
  signal(error ("No data for dictionary \"en_ZA,af_ZA\" in
‘ispell-local-dictionary-alist’ or ‘ispell-dictionary-alist’"))
  error("No data for dictionary \"%s\" in `ispell-local-dictionary-alist'
or `ispell-dictionary-alist'" "en_ZA,af_ZA")

But from the commandline I can use it:
$ hunspell -d "af_ZA,en_ZA" .emacs

Anyhow there is progress.  I can at least use one dictionary at a time.

Thanks again.

Johann

Question about jessie

[Cédric Devillers]

Hello,

just a quick question about Jessie.

In recent days, the directories jessie-backports and jessie-updates have 
been removed from the main repositories.
jessie-backports is now available on the site "archive" and 
jessie-updates has totally disappeared.

The jessie distribution is supposed to be in LTS until 2020.
What is the reason for these directory movements? Is this normal?
In addition, the directory jessie-backports is indicated as expired 
(InRelease).


Thank you in advance for the information you can provide me about it.

Regards,

CD

I think that Lisp was used in AI because it was the best language you
could find to code smart algorithms on... Figure implementing mapcar
in assembler or FORTRAN :)

I would guess either some kind of rapid transit snafu or data base
corruption, not necessarily in that order.

This is unacceptable not to read the apt-cdrom manpage ;-)
The package to file a bug against is CTK ;-)

Erm, this guide walks you through the process of getting / root on ZFS,
though it does make you do a little extra legwork to set up a Z-RAID.
I've followed this guide myself for an encrypted ZFS setup on Debian
with my Laptop.

You are aware that ZFS does not use traditional MDADM, but rather
integrates the RAID functionality directly into the file system, right?

Hello.

I read this guide, but this implies to have a separate MD raid on disk. It is 
not fully /boot on ZFS.
