Ubuntu 18 : Slack vs Teams ( CPU et Memory )

76 x served & 8 x viewed

J’ai fait un petit script :

#!/bin/bash    
psrecord --interval 1 --duration 300 --plot slack-tail.png  $(pgrep slack | tail -n 1) &
P1=$!
psrecord --interval 1 --duration 300 --plot teams-tail.png  $(pgrep teams | tail -n 1) &
P2=$!
psrecord --interval 1 --duration 300 --plot slack-head.png  $(pgrep slack | head -n 1) &
P3=$!
psrecord --interval 1 --duration 300 --plot teams-head.png  $(pgrep teams | head -n 1) &
P4=$!
wait $P1 $P2 $P3 $P4 
echo 'Done'

Résultat rapide (car seulement sur 300 secondes ) :

Slack :

Microsoft Teams :

Je vais essayer de faire un script pour faire la somme des process … car j’ai plus de deux process par softs :

$ pgrep slack
2171
7960
7965
7969
8011
8020
$ pgrep teams
7681
7700
7777
7809

Ubuntu : ntfsfix ( chkdsk sous Windows) pour fixer les problèmes NFTS sous Ubuntu.

102 x served & 17 x viewed

Voici un petit exemple pour fixer les problèmes NTFS sous Ubuntu :

$ sudo mount /dev/sdc2 /media/usb-drive/
$MFTMirr does not match $MFT (record 0).
Failed to mount '/dev/sdc2': Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.
$ sudo ntfsfix /dev/sdc2

La première étape de l’installation :

$ sudo apt-get install cmake clang bison flex xz-utils libfuse-dev libudev-dev pkg-config libc6-dev:i386 linux-headers-generic gcc-multilib libcap2-bin libcairo2-dev libgl1-mesa-dev libtiff5-dev libfreetype6-dev libfreetype6-dev:i386 git libelf-dev libxml2-dev libegl1-mesa-dev libfontconfig1-dev libbsd-dev

Ensuite on charge les sources :

$ git clone --recursive https://github.com/darlinghq/darling.git

Après on fait le build :

$ cd darling
$ mkdir build && cd build
$ cmake ..
...
CMake Error at cmake/FindFFmpeg.cmake:86 (message):
  Could not find libavcodec or libavformat or libavutil
...

J’ai donc fait ceci :

sudo sudo apt-get install -y \
    libavformat-dev libavcodec-dev libavdevice-dev \
    libavutil-dev libswscale-dev libavresample-dev

J’ai relancé un cmake :

$ cmake ..
...
CMake Error at /usr/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find PulseAudio! (missing: PULSEAUDIO_LIBRARIES
  PULSEAUDIO_INCLUDE_DIRS)
...

J’ai donc essayé ceci :

$ sudo apt-get install pulseaudio libpulse0 
...

Mais j’avais déjà les librairies. J’ai donc fait le plan B :

$ sudo apt-get install libpulse-dev pulseaudio apulse

Je relancé un cmake pour la troisème fois :

$ cmake ..
...
CMake Error at /usr/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find GIF (missing: GIF_LIBRARY GIF_INCLUDE_DIR)
...

J’ai donc essayé ceci :

$ sudo apt-get install libgif-dev

La quatrième cmake est donc le bon :

$ cmake ..
...
$ make
...
ld: file not found: /System/Library/PrivateFrameworks/FMDB.framework/Versions/A/FMDB for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

make[1]: *** [src/external/JavaScriptCore/CMakeFiles/JavaScriptCore.dir/all] Error 2
Makefile:129: recipe for target 'all' failed
make: *** [all] Error 2

A noter que le reste de l’installation fonctionne :

$ make lkm
...
$ sudo make lkm_install
...

Je vais refaire un test avec la commande :

$ git clone --recurse-submodules https://github.com/darlinghq/darling.git

Puis j’ai relancer le build :

$ time sudo make
...

Sniff.

UPDATE :

J’ai finalement réussi (merci Luc) :

Internet Explorer sous Ubuntu 18.04 , c’est possible ? (en mode virtualbox et non libvrt)

Je fais donc suite à mon précédent article : http://www.cyber-neurones.org/2020/04/internet-explorer-sous-ubuntu-18-04-cest-possible-jai-pas-reussi/ . J’ai fixé un des problème ici : http://www.cyber-neurones.org/2020/04/ubuntu-18-issue-lvm2-lvmetad-service-unit-lvm2-lvmetad-socket-is-masked/ .

Maintenant j’essaye en mode virtualbox :

Vagrant is currently configured to create VirtualBox synced folders with
the `SharedFoldersEnableSymlinksCreate` option enabled. If the Vagrant
guest is not trusted, you may want to disable this option. For more
information on this option, please refer to the VirtualBox manual:

  https://www.virtualbox.org/manual/ch04.html#sharedfolders

This option can be disabled globally with an environment variable:

  VAGRANT_DISABLE_VBOXSYMLINKCREATE=1

or on a per folder basis within the Vagrantfile:

  config.vm.synced_folder '/host/path', '/guest/path', SharedFoldersEnableSymlinksCreate: false

==> default: Preparing network interfaces based on configuration...

    default: SSH address: 127.0.0.1:2222

    default: SSH auth method: password


Ensuite il faut lancer VirtualBox :

Et on a ceci :

Le mot de passe est : Passw0rd! ce qui donne Pqssz)rd/ ou encore Pqsszàrd1.

Ensuite il est préférable de passer en Francais :
