Install Darktable on Fedora 15
If you are a photographer you probably work with RAW images and many other images. There are not many programs available for Linux that are really good for managing and editing out there, but they are growing. One such program is Darktable.
Darktable is an open source photography workflow application and RAW developer. A virtual lighttable and darkroom for photographers. In manages your digital negatives in a database, lets you view them through a zoomable lighttable and enables you to develop raw images and enhance them. On the Windows side of the coin there is Adobe Photoshop Lightroom.
First we need to add the repo. Open a terminal.
$ cd /etc/yum.repos.d
$ sudo wget http://dt-nightly.hamsterkollektivet.se/dt-nightly.repo
$ sudo yum update
Now let’s install it.
$ sudo yum -y install darktable
Now you are set to use this powerful editing program in Linux !!
Install Virtualbox 4.1.8 Fedora 15
Recently I wanted to add a small network to test Windows 2008 clusters and to use for training for Windows 2008 R2 certification. To do this with minimal costs I looked to virtualization. To do that I had to install Virtualbox or VMWare Workstation. While VMWare workstation is great, it costs money., so Virtualbox is the way to go. This post describes how to install Virtualbox on Fedora 15. Look for future posts on how to build a virtual cluster using FreeNAS and Virtualbox.
Open a terminal session on your system.
Copy and import key
$ sudo wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | rpm --import -
Add Virtualbox repo to /etc/yum.repos.d.
$ cd /etc/yum.repos.d
$ sudo wget http://download.virtualbox.org/virtualbox/rpm/fedora/virtualbox.repo
$ sudo yum update
Install kernel-devel kernel headesr gcc and dkms
$ sudo yum -y install kernel-devel kernel-headers dkms gcc gcc-c++
Install Virtualbox
$ sudo yum install VirtualBox-4.1
Add Virtualbox, or your id, user to Virtualbox user group
$ sudo usermod -a -G vboxusers
Now you can open up Virtualbox and start adding VM’s
Mounting a NAS read / write on Fedora 12 +
Recently upgraded my NAS and had an issue where I could mount the device on Fedora but would only in Read Only mode. For my purpose I was mounting with a script to my home directory but wanted to add it to a directory called share on my root in read / write mode by adding it to /etc/fstab after figuring out why I could not write to the directory.
Part of the solution is to add UID and GID of my id, username and password for connecting to the NAS and the rw flag. Since I wanted to mount from /etc/fstab I created a directory off the root called /share and changed ownership to my id.
$ sudo mkdir /share
$ sudo chown -R fooman:fooman /share
Next is to create the /etc/fstab entry
//192.168.1.100/share /home/fooman/share cifs rw,username=fooman,password=foo,UID=500,GID=500 0 0
Finally mount it
$ sudo mount /share
If you want to just have a command or a script to mount it to your home directory just create one with the below syntax after creating a share directory in your home directory.
$ sudo mount -t cifs //192.168.1.100/share ~/share -o rw,user=fooman,password=foo,UID=500,GID=500
Hope this helps you as it helped me !!!
