PortableApps

Remove splash screen

In the same directory as AppPortable.exe Put AppPortable.ini with proper parameter

KiTTY

  • In Window → Appearance, Use Lucida Console instead of Courrier
  • In Connection → Data:
    • Define an auto-login username
    • Define a command, like an auto screen start: screen -q && read -n1 -r -p "Press any key to exit, or Ctrl+C to continue." && exit

Fix screen output

In the setting for a connection, go to :

  • Window > Appearance, Change font to Lucida Console
  • Window > Translation, Change remote character set to ISO-8859-1:1998 (Latin-1, West Europe) … but this will break other softwares.

Port Forwarding

  1. In the setting for a connection, to go to Connection → SSH → Tunnels
  2. Add the port you want to forward:
    • Source port: the client port you want to listen to
    • Destination: the port on the target you want to be connected to

Duplicati

A very good backup solution, if you have a good storage provider.
In Ubuntu, installed in /usr/lib/duplicati/, and use ' in command line

Command-line Duplicati client

  1. Clone the repo and navigate in the folder
  2. Login ./duplicati_client.py login http://localhost
  3. Do an action:
    • Regarding the server:
      • ./duplicati_client.py status
      • ./duplicati_client.py list backups
    • Regarding one backup:
      • ./duplicati_client.py get backup 1
      • ./duplicati_client.py run backup 1
      • ./duplicati_client.py run backup 1
    • Regarding backup configuration:
      • ./duplicati_client.py export 1
      • ./duplicati_client.py update 1
  4. Logout ./duplicati_client.py logout

Command-line interactions

Documentation for command line is here.
Useful commands:

  • Duplicati.CommandLine.exe delete <storage-URL> --version=<int> to delete all files that belong to version <int>
  • Duplicati.CommandLine.exe test <storage-URL> <all/#> [<options>] to check either all or a number (#) of sample

Troubleshooting:

  1. Do a repair command from the command-line web interface
  2. Do a list-broken-files to check affected files and versions
  3. Do a purge-broken-file to remove the above

Paint.Net (Paint/Photoshop alternative)

Visual Studio Code (Text/Code editor)

LTeX (Grammar/Spell checker)

Cygwin (Linux on Windows)

OpenJDK (Java)

VirtualBox (Virtual Machine)

  • Fix permissions with shared folders on Linux
    • Message in Ubuntu: This location could not be displayed. and You do not have the permissions necessary to view the contents of "sf_Manager".
    • Solution: sudo adduser $USER vboxsf and reboot
  • Compact a virtual hard drive .vdi
    1. Defragment the disk
    2. In the guest:
      • Linux: dd if=/dev/zero of=/var/tmp/bigemptyfile bs=4096k ; rm /var/tmp/bigemptyfile
      • Windows: sdelete.exe c: -z from Sysinternals
    3. Shutdown
    4. Run VBoxManage.exe modifymedium --compact c:\path\to\thedisk.vdi
