crontab on MacOS

  • Example
crontab -e
00 20 * * * ctest -S myScript.cmake > myScript.log 2>&1
  • Problem:

When I create a cronjob with 

crontab -e

I get the error message: 

crontab: temp file must be edited in place
  • Solution:

Use the 'nobackup' option in VI: 

:set nobackup
:set nowritebackup

crontab: installing new crontab

Change shell in Debian

  • Type:
 chsh
  • Type your password
  • Logout and login again.
  • Set up the .zshrc file.

Associate hostname with IP address for SSH

  • Dynamic way:

Add in /etc/dhcp3/dhclient.conf 

 send host-name "<your_host_name>";
  • Static way: (not as good)

Add IP address and hostname in /etc/hosts (Linux) or C:/WINDOWS/system32/drivers/etc/hosts (Cygwin): 

     102.54.94.97     rhino.acme.com          # source server
      38.25.63.10     x.acme.com              # x client host
  • On Debian, install openssh-server

SSH without password

Add to .ssh/config 

 Host <remote_host_name>
   User <your_user_name_on_remote_host>

colorscheme torte

Create a plugin directory if it does not exist: 

mkdir ~/.vim
mkdir ~/.vim/plugin

Download the a.vim into the plugin directory 

http://www.vim.org/scripts/script.php?script_id=31

Restart gvim.

VI Convert tabs to spaces (copied from http://www.gammon.com.au/smaug/vi.htm)

Type a VI command using ':set' 

Set tabs to every 2 characters  	:set ts=2
Convert tabs to spaces in future 	:set et
Do not expand tabs 	                :set noet
Fix existing tabs (convert to spaces) 	:%retab
Show tabs visually, and end-of-lines 	:set list
Do not show tabs and end-of-lines 	:set nolist

Or add those commands to your ~/.vimrc 

set textwidth=78  "wrap lines longer than this length
set tabstop=2     "tabs stops every 2 characters
set shiftwidth=2  "size of a tab
set expandtab     "tabs to spaces

Building CMake on Debian

Build VTK for Release

To create an executable that contains all the libraries, so you don't need to ship the dlls with it: CMake options: 

Build Static
Replace /MD with /MT

VC Express options: 

Build Release

Mount on Linux using Samba

1. Create mount points . 

mkdir /mnt/nas2 /mnt/ruwenda /mnt/nas3

2. add the following lines to your /etc/fstab file : 

//kitwarenas2/Share /mnt/nas2    smbfs   defaults,guest,rw     0       0
//ruwenda/E         /mnt/ruwenda smbfs   defaults,guest,rw     0       0
//kitwarenas3:/Share /mnt/nas3 nfs     rw,user,exec,noauto         0       0

Build VTK with Offscreen Rendering on Linux

OSMesa (Off Screen Mesa) is a library that does rendering and does not need a graphics context. You can use it on a server that does not have a graphics card or any graphics capability. To use VTK with OffScreen Rendering on Linux, you need to compile VTK with the OSMesa option on. 

Configure VTK using CMake.
Hit 't' for Advanced Options
Turn VTK_OPENGL_HAS_OSMESA ON
Hit 'c' to configure again.
Set path to include dir and library:
OSMESA_INCLUDE_DIR
OSMESA_LIBRARY
Turn VTK_USE_OFFSCREEN ON if you want offscreen by default.

If you built Mesa from source and link to it, your dependencies should be ok. If you installed the OSMesa packages for Debian and did not build VTK from scratch, your dependencies might be messed up. Then once you have configured your CMakeLists.txt, check that this CMakeLists.txt variable is set to zero, and then type make: 

VTK_USE_GLX_GET_PROC_ADDRESS_ARB:INTERNAL=0

On Debian, I installed: 

libosmesa6
libosmesa6-dev

To check if Mesa was installed correctly, you can type in a terminal: 

$ glxinfo | grep renderer
OpenGL renderer string: Mesa X11

It should return the line above. In case you get the Nvidia drivers for example, then Mesa was not installed correctly. To get info about OpenGL libraries used by a VTK 6.0 build, you can use the test LoadOpenGLExtensions.

When you run your VTK code with Mesa, you can turn offscreen rendering on in your application: 

RenderWindow->OffScreenRenderingOn();

and no render window will pop up.

To generate screenshots, use: 

vtkWindowToImageFilter.
