Debian Wheezy: resize/scale images from command line.

First of all you need to have installed imagemagick.
If no, install it from terminal as root so:

Now you are ready to convert input.jpg file into output.jpg file for a 1000 pixels of width and 500 pixels of height....

convert -scale 1000x500 input.jpg output.jpg 

The scale method, in this case, depends of the height and the weight of your image.
So if your image is 2 pixels of width and 1 pixels of height the perform will gone exactly.

Differently the perform will be approximated.

If you want to force the scale performing to make a image of gived dimensions...

convert -scale 1000x500! input.jpg output.jpg

If you have multiple files to convert use this:

for i in $( ls *.JPG); do convert -resize 1300x500 $i $i; done

How to set up CVS server under Debian 6.0.6, and connecting to it with Eclipse

First of all ensure you have ssh server....
If no see here....
After update repository indexes and install.....

apt-get update
apt-get install cvs


Now we see how to quickly configure it.....
create repository user and repository group

useradd repository

add user repository to repository group  

usermod -a -G repository repository

add user your_user to repository group

usermod -a -G repository your_user

create root directory for cvs

mkdir /home/repository

initialize cvs

cvs -d /home/repository init

give the right permissions to folders

chown -R repository:repository /home/repository
chmod -R 770 /home/repository
chmod 770 /home/repository/CVSROOT

Now provides to give the first import as cvs administrator, so in this case, as repository user I give the follow

cvs -d /home/repository import -m "Initial import" project_name username_that_add_the_first_sources project_version

Working with Eclipse, you go under New --> Other --> CVS Repository Location
and add as parameters...
- connection type: extssh
- host: hostname or ip of the machine where you installed the cvs, in my case localhost
-  username and password: the username, of system, that previously you added to the repository group and its password
- repository path: as in our example, /home/repository, that's the home directory that's you have setted for your cvs installation

Debian, upgrading to 2.6.30 kernel: rt2879sta firmaware, support for Ralink rt2800U and rt3000U chipsets

If you have a wifi device based on Ralink RT2000U or RT3000U chipset, and you have upgraded your kernel to 2.6.30 version, surely you will get an error on the rt2800(or some among those rt2070, rt2770, rt2870, rt3070, rt3071, rt3072) firmware, no more loaded.
Something like this:

rt2800 firmware not loaded
SIOCSIFFLAGS: Operation not permitted

The raison is that on the firmware has been removed from the 2.6.30 kernel image.

So, ensure you have in /etc/apt/sources.list the following line:

If you have not it, insert and give aptitude update...

After give the following:

aptitude install firmware-ralink

Debain 6.0.4: quick samba installation and configuration

Here is a quick description to how to install samba server and configure it in order to share folder on the network.

Giving 
apt-cache search samba
results:

[...]

libsmbclient-dev - development files for libsmbclient
libsmbclient - shared library for communication with SMB/CIFS servers
libwbclient0 - Samba winbind client library
samba-common-bin - common files used by both the Samba server and client
samba-common - common files used by both the Samba server and client
samba-dbg - Samba debugging symbols
samba-doc-pdf - Samba documentation in PDF format
samba-doc - Samba documentation
samba-tools - Samba testing utilities
samba - SMB/CIFS file, print, and login server for Unix
smbclient - command-line SMB/CIFS clients for Unix
swat - Samba Web Administration Tool
winbind - Samba nameservice integration server
smb2www - SMB/CIFS network client with a web interface

[...]

So run

apt-get install samba smbfs smbclient

to install these three packets....

during installation, it performs default configuration

after....

So next commands.....

adduser guest --home=/home/public --shell=/bin/false --disabled-password

to create a guest user to use only as samba default user....

chmod -R 0700 /home/public

chown -R guest.guest /home/public

These commands configure the sharing in way of every user can create a content(file or folder)

into the shared folder.

No one may edit the content created by something others.... 

If you want some of differently, change the permission mask.....

Now edit /etc/samba/smb.conf

adding after the row 

obey pam restrictions = yes

insert these others rows: 

guest account = guest
invalid users = root

and in the ****Authorization**** section,  these two rows.....: 

; security = user

security = share

In the sharing section add:

# SHARED DIR
[shared]
   comment = shared
   read only = no
   path = /home/public
   guest ok = yes
   guest only = yes
   create mask = 0600
   directory mask = 0700
 

Fine...... restart samba:

 /etc/init.d/samba restart

and all is done.....

 Bye....
