Well, it's still getting security updates; I see one dated 2017-09-07.

As it happens, there was a question that illustrated differences
in their features just yesterday:

https://unix.stackexchange.com/questions/463926/extracting-rar-files-with-unrar-free-and-unar-need-progress-completion-and-ti

so I guess it depends what people's priorities are. Why would you
want it removed?

I think I did answer this once before David, but I was useing what looked 
to be a simple install, 1 up from the advanced gui install at the bottom 
of the start screen list.

I've been busy getting a verdict and script from the doc today, bought a

caring for the missus, and have not tried another install, but will 
tommorrow using the Advanced mode.

As I suggested before, compatability with existing scripts is one 
reason--unar has incompatible command line syntax. (Although along those 
lines, having /usr/bin/unrar be an alternative between two programs with 
incompatible options as currently is horrible.) There are a number of 
other packages which depend on or recommend unrar, which would 
presumably need to be modified to work with unar. (And now I'm wondering 
how many of them break if unrar-nonfree is installed.) In general things 
aren't removed just because there are options.

Dear Reco and all,

Except for Michael it seems nobody understood the question I was asking.

There is unrar-free and unrar, both are different  packages  -

$ apt-cache policy unrar-free
unrar-free:
  Installed: 1:0.0.1+cvs20140707-4
  Candidate: 1:0.0.1+cvs20140707-4
  Version table:
 *** 1:0.0.1+cvs20140707-4 500
500 http://deb.debian.org/debian buster/main amd64 Packages
100 http://deb.debian.org/debian unstable/main amd64 Packages
100 /var/lib/dpkg/status


$ apt-cache policy unrar
unrar:
  Installed: (none)
  Candidate: 1:5.5.8-1
  Version table:
 1:5.5.8-1 500
500 http://deb.debian.org/debian buster/non-free amd64 Packages
100 http://deb.debian.org/debian unstable/non-free amd64 Packages


There is also package unar which is a different  package altogether -

$ apt-cache policy unar
unar:
  Installed: 1.10.1-2+b2
  Candidate: 1.10.1-2+b2
  Version table:
 *** 1.10.1-2+b2 500
500 http://deb.debian.org/debian buster/main amd64 Packages
100 http://deb.debian.org/debian unstable/main amd64 Packages
100 /var/lib/dpkg/status

See the different  version numbers and either $aptitude show
$PACKAGENAME or tracker.debian.org/$PACKAGENAME to show the
differences.

My query is/was a more simpler one.

The last commit to unrar-free was done in 2004 and that 's about  it .
You can find the commits in /usr/share/doc/unrar-free/changelog.gz

The homepage given doesn't  exist more https://gna.org/projects/unrar/
and the only kind thing about  the package repo. is somebody made a
mirror on github for posterity purposes when the original URL was shut
 down.

https://github.com/Lesik/unrar-free

also see http://www.unrarlib.org/ for some documentation from that time.

So the question is, are there any corner cases where unrar-free excels
unar and if not  can or should it  be removed from the Debian repo. ?

The question has nothing to do with unrar which is non-free but only
asks about packages in Main repo.

Uncommanded shutdowns may be caused by overheating. What is your CPU 
temperature under load? Your BIOS may shut your computer down if a 
temperature limit is exceeded. Manufacturer? Laptop? Model? CPU? BIOS 
version?


I use and recommend memtester, which can be run after a normal boot 
("userspace"). I found that multiple concurrent instances of memtester 
detected memory problems not found by memtest86+. Run memtester as root 
so it can memlock.  Because memtester runs after a normal boot, you can 
use a desktop temperature monitoring tool. I use the Xfce sensors applet 
polling at one second intervals, and this script:


#!/bin/bash
tmax=0
while true; do
t=$((`cat /sys/class/hwmon/hwmon2/temp1_input`/1000))
tmax=$((t>tmax?t:tmax))
echo "`date '+%T'`: $t / $tmax"
sleep 1
done

I also use thermald to limit CPU temperature (but my problem was not 
temperature). I use a custom service file to reduce the polling interval 
to one second.


Another useful test tool is mprime  
(AKA Prime95 on Windows). Be sure to disable AVX with "CpuSupportsAVX=0" 
in local.txt because synthetic AVX tests can be used to generate 
excessive and unrealistic amounts of heat.

Proton for Steam on Debian.

[Dominic Knight]

Does anyone have any knowledge or experience of this to share. Or even
any thoughts on security which could be useful.

https://github.com/ValveSoftware/Proton/

Under the install for Linux section it says to set up a Debian machine
to run the software on as it requires latest drivers etc. Well, I have
one of them of course - running steam in a flatpak on Buster, but would
be interested to know about game compatabilty (most especially for
Phantom Doctrine if anyone has tried that) of Windows only games using
Steams Proton/Wine configuration.

I'm not sure I understand using DHCP to get the ipaddr for the
network running through the USB connection. Could you explain?

Aside: I will get my knuckles rapped if I explain how I do this
sort of connection using the IPv6 link addresses which means
I don't have to ifup anything before I can transfer files.

Inside there you can add the other two DVDs, and then Synaptic will

Ok. Comment fait-on pour ne plus utiliser du tout Network-Manager ?

Est-ce que le choix du bureau (Gnome, XFCE, etc.) a une incidence sur la

Ce n'est pas une surprise que utiliser un truc automatique et "hotplug"
comme networkmanager ne soit pas totalement en harmonie avec une
méthode statique "obsolète" quoique efficace (et qui a du être mise a
jour de fait).

Je n'ai pas regardé la doc actuelle, mais il me semble bien avoir vu
dans les messages de APT, au fur et a mesure des mises a jour, toute
les informations au sujet de ifupdown et resolvconf.

Moi j'aurais tendance a ne pas mixer un machin déjà assez compliqué,
Networkmanager, avec une autre méthode de connexion, c'est a dire ne
pas utiliser du tout Networkmanager pour une configuration fixe. Dans
le cas contraire, je configure Networkmanager et pas une deuxième
méthode de connexion.

Même si je répond sans avoir relu la doc d'install, je suis presque
certain que l'essentiel est dedans.

Ce n'est pas une surprise que utiliser un truc automatique et "hotplug"
comme networkmanager ne soit pas totalement en harmonie avec une
méthode statique "obsolète" quoique efficace (et qui a du être mise a
jour de fait).

Je n'ai pas regardé la doc actuelle, mais il me semble bien avoir vu
dans les messages de APT, au fur et a mesure des mises a jour, toute
les informations au sujet de ifupdown et resolvconf.

Moi j'aurais tendance a ne pas mixer un machin déjà assez compliqué,
Networkmanager, avec une autre méthode de connexion, c'est a dire ne
pas utiliser du tout Networkmanager pour une configuration fixe. Dans
le cas contraire, je configure Networkmanager et pas une deuxième
méthode de connexion.

Même si je répond sans avoir relu la doc d'install, je suis presque
certain que l'essentiel est dedans.

Alas java .class compiled with java 10 cannot be run by a java 8 VM, so
it is difficult.

I'll keep a copy of java 8 or 10 for those things.

The package lists themselves should be (I think!) in the

packages (and tell you to insert whatever DVD is needed
while installing).

Which program are you using to install packages? Dpkg?
Synaptic?

I hope it's not something based on Webstart? Because Webstart will no
longer be part of Java 11. So I guess at least some of us will have to
keep a copy of a JRE with javaws around for some time.
That is also the reason why the Java 8 support in the current java-package

and I think there is no real need for this repackaging of Oracle JREs

The button is just a key like any other.  When running X11 in Debian, it
generates the XF86Send key event when pressed.  You can, of course, bind
this to anything you want, including some voice assist application if
such were to exist...

I've got same result as previous test.
tests with dd command are executed directly on the server.


Can you rebuild the partition? If so, unmount it then perform the dd 
directly to the device. (of=/dev/sda2 or whatever) What's the hardware 
raid vendor? Honestly, the performance of ext4 partition is also 
horrible, just not as bad as the xfs partition. What's the hardware raid 
model? Does it have a battery backed cache? (I will guess not, because 
the test is only 1G and that should fit into most current caches?) If 
the test directly to the partition shows good performance, then it might 
be an alignment issue; try recreating the fs with `mkfs.xfs -d 
su=64k,sw=2 ...`. If the performance is the same to the raw partition 
(and still much worse than the root partition) then the partition 
alignment itself might be off--which means recreating the partitions. 
(fsck and mkfs.xfs normally handle this automatically, but that depends 
on the raid controller+driver passing the information up, and per your 
xfsinfo output, that didn't happen.)

The button just starts an Android app (assuming Android is

Gemini PDA -- Voice assist -- does that work with all the OSs

[rhkramer]

I now see that the Gemini PDA is available with 4 operating systems (maybe one 
is still vaporware), but they are Linux, Android, and 2 versions of Sailfish.

It has a voice assist button, and I'd like to know more about how this works:

   * does it work with all the operating systems available on the Gemini?  If 
not, which OSs does it work with?  

A somewhat related / alternate question is whether that voice assist is 
totally hardware driven (which I doubt) or does it require software (in which 
case, that software might work only in some of the available OSs.

   * presumably, for voice assist to work while the Gemini is in your pocket 
(which is mentioned on at least one webpage), the Gemini must be on and booted 
into an appropriate OS?

how are you testing this? 
I tested write speed with dd command like "dd if=/dev/zero

The 10 MB/s for the data partition also correspond to the behavior I get 
in real situation, when I copy a big file on NFS, 12GB are copied 
quickly then hang for 15 or 20 minutes. When I copy big file with scp, 
It copy quickly the at the beginning then decrease to 10 MB/s till the end.

it's unlikely that the filesystem is the issue, both xfs and ext4 are

Just came to my mind: There is a free (or trial?) version available of Amazon 
WorkSpaces. If you have an AWS account, you should get the latest MS Office

The main point so far was to aid debugging because you could be certain
on which code base you build and run it.
If everyone is using a slightly different build it's quite hard to track
down bugs. In one of my past jobs someone actually found three bugs in
the JVM and we once were victim of a regression in the expat parsers
in a few Java releases.

If you can not say for sure at which exact version your developers are,
and which one you use in production, and that often across Windows, OS X,
and various Linux distributions, the situation can be quite unpleasant.

I actually do not care for my desktop system at home, but if you run
a lot of stuff on the JVM in production, it can be an issue.

I'm currently maintaining my own fork because I did not get around
to properly hijack the package. I had at some point contact with one
of the prior maintainers but we could not get around merging my Java 9
changes at that point.

So for now my fork is here:

Usage instruction if you do not want to build a Debian package out
of it:
https://sven.stormbind.net/blog/posts/deb_java-package-oracle-jdk9/


It's not completely polished but I'm reluctant to invest more time
because I assume we all move on to OpenJDK in some form in Januar 2019.

Context:
As far as I know Oracle JRE/JDK builds will be only available for paying
customers on a contract by September 2018 for Java 11 and January 2019
for Java 8. At that point everyone else will propably migrate to some form
of OpenJDK. If it's the one shipped by your distro or 3rd parties like
Azul needs to be determined on a case by case basis I guess.
There will still be reference binary OpenJDK builds published on
jdk.java.net but I'm not sure if it's worth to provide support for them
in java-package.

Slow XFS write

[Martin LEUSCH]

Hi,


I have a NFS server with a hardware RAID5 on 3 HDD of 6 TB. I have a 
system partition with ext4 and a data partition with XFS.


I get only 10 MB/s in write speed on the XFS data partition and 80 MB/s 
on the system partition.



XFS mount option:

/dev/sda4 on /var/srv/nfs type xfs (rw,relatime,attr2,inode64,noquota)

Is there a way to have better performance? Is XFS a good choice in this 
situation?

Re: xfce4-session launched from .xinitrc, clobbers xrandr settings

[Zenaan Harkness]

OK, so I thought I'd wait 3 weeks, and yeah, I know, it's only been
20 days, but hey, color me impatient.

What I ended up doing is just adding an xrandr entry to my xfce4
session, but this seems to slow the startup of the GUI starting -
i.e. it seems like XFCE4 does some internal default monitor (xrandr)
layout, then runs my script which sets my preferred xrandr config/
layout.

Although I can't really be sure - I'm not sure how to properly test
this, as it could just be a time/impatience illusion.

Thoughts?

À l'époque, j'avais lu dans la doc que le compte redmine devait être de type 
système. Je me suis aperçu plus tard que cela n'était nécessaire que lorsqu'on 
utilisait le serveur webrick intégré à Redmine, afin que ce dernier puisse 
écouter sur les ports 80 et 443. Mais cela n'est pas nécessaire lorsqu'on 
utilise un serveur Apache ou NGinx en frontal.

Le compte sous lequel tourne la seule instance de Redmine que j'administre 
encore a pour uid 1005. Il ne s'agit donc pas d'un compte système.

woops. openssl 1.0.2 doesn't have 'list' command (1.1.0 has 'list').
Instead, I can 'openssl ciphers' command.

$ openssl ciphers -ssl3
