Continuous Page Scrolling in Evince

pradeeper — Fri, 23 Oct 2009 00:10:49 +0000

Evince is a lightweight document viewer specially PDF documents under GNU/Linux desktops. I have used both Adobe Acrobat Reader (Linux port) and Evince some time now, and it is clear that Evince is much lighter than Adobe Acrobat. If you’re trying to get printouts of the PDF then Adobe Acrobat gives better results.

However, recent versions of Evince gave a significantly annoying behaviour (specially the version that’s in the Ubuntu) when I read PDF that has multiple pages. When I want to scroll one page to another, Evince doesn’t allow me to do that with the (UP/DOWN) arrow keys or mouse scroll. It seems like a small issue but if you’re a frequnt user of the tool then you would recognize this as a pretty important feture. So workeround is so simple, go to View on the top menu bar in the Evince and select Continuous. That’s it

Have you thought about extending your OpenOffice package capability by adding an extension, just like we do in FireFox? Well… at least I didn’t know. Checkout the OOo site for the extensions,

http://extensions.services.openoffice.org/

There are number of good plug-ins and templates that may essential in day to day use. Installation of the extension is extremely easy and pain less.

HP Laserjet p1005 with Ubuntu

pradeeper — Mon, 14 Sep 2009 10:40:54 +0000

HP Laserjet p1005 is working perfectly with Linux but only issue is setting it up initially. Console base installation depend on some GCC libraries and you have to manually install them before run the installation script. Install following dependecies,

sudo apt-get install libcupsys2 cupsddk cupsddk-drivers libcupsys2-dev
cupsys-bsd libcupsimage2-dev libdbus-1-dev build-essential gs-esp
openssl libjpeg62-dev libsnmp-dev libtool libusb-dev python-imaging
policykit policykit-gnome python-qt4 python-qt4-dbus python-dbus
python-gobject python-dev python-notify python
python-reportlab libsane libsane-dev sane-utils xsane

Download the latest driver from HPLIP site.

Extract it on your hard disk and run the install script.

You might want to re-install hplip from the synaptic or apt-get again, Thanks Mifan!

Jo has created a poll to select which DVCS to adopt in Sahana Project. It’s interesting to see the poll results on Doodle as it progress. There’s a clear preference towards Bazaar than GIT. At the time I write this post, there were 17 votes for Bazaar and 12 for Git. -

Tool seems like pretty neat and cool. It has it’s own wizard that can connect with most of the popular blog platform out there and lots of pretty tools.

Subversion with mulitple user access levels on Debian

pradeeper — Sat, 08 Nov 2008 20:07:46 +0000

Most of the organizations who are in to software development are maintaining a source code repository these days. Requirement can be complex if you’re maintaining multiple projects with different user (most of the time software developers) access levels. Luckily, there are dozens of free/open software solutions for this. Among them, Subversion and CVS are in the top of the list.

This short HOWTO will explain the steps to implement Subversion with different user level access to the repository on Debian based system.

1) Make sure that the system is up to date with all the patches and updates,

apt-get update && apt-get upgrade

2) Install Subversion, Apache2, PHP, Webdav and other related packages,

apt-get install subversion apache2 php5 libapache2-svn websvn

3) Creating the repository on the newly implemented Subversion,

My preferred location to place repository is under /opt/ directory, feel free to change the location as you please. Create the directory structure,

mkdir -p /opt/acme/

svnadmin create –fs-type fsfs /opt/acme/myrepo

4) In this method, Subversion only maintain the repository, Apache WebDAV module is the one that handle write and user permission. Hence, Give Apache to access the repository,

Create a group for Subversion Administrators and add yourself to the group,

groupadd svnadm

addgroup pradeeper svnadmin

Change the ownership of the repository to the Apache user (which is www-data in the debian base systems),

chown -R www-data /opt/acme/*

Change the group-ownership to the svnadm group,

chgrp -R svnadm /opt/acme/*

Set the permission to the repository directory where only Apache user and svnadm has full access and others have no access to the directory,

chmod -R 770 /opt/acme/*

5) Setting up WebDAV,

ln -s /etc/apache2/mods-available/dav_svn.conf /etc/apache2/mods-enabled/dav_svn.conf

ln -s /etc/apache2/mods-available/dav_svn.load /etc/apache2/mods-enabled/dav_svn.load

Restart the Apache to take the new configuration,

/etc/init.d/apache2 restart

6) Next step is to create an Apache VHOST file for the repository. This will give you the oppertunity to access the repository using a URL. (For example, svn..com),

In Debian, default vhost file location is /etc/apache2/sites-available/ , feel free to create a vhost with appropriate settings for you. Here is my settings,

NameVirtualHost *

ServerAdmin

ServerName svn.

DocumentRoot /usr/share/websvn

Options FollowSymLinks

AllowOverride None

Options Indexes FollowSymLinks MultiViews

AllowOverride AuthConfig

Order allow,deny

allow from all

ErrorLog /var/log/apache2/error.log

# Possible values include: debug, info, notice, warn, error, crit,

# alert, emerg.

LogLevel warn

CustomLog /var/log/apache2/access.log combined

ServerSignature On

Alias /doc/ “/usr/share/doc/”

Options Indexes MultiViews FollowSymLinks

AllowOverride None

Order deny,allow

Deny from all

Allow from 127.0.0.0/255.0.0.0 ::1/128

Add following lines to the above vhost file, Make sure that below section is within the opening and closing tags

DAV svn
SVNPath /opt/acme/myrepo
AuthType Basic
AuthName “Subversion Repository”
AuthUserFile /etc/apache2/dav_svn.passwd
AuthzSVNAccessFile /etc/apache2/dav_svn.authz
Require valid-user

7) Create WebDAV access file. Initial section would define the group memberships and later sections define the permission level to the each section (directory) of the repository. Please refer following sample dav_svn.auth file,

[groups]
pm = pradeeper, mifan, jo
devset1 = smith, jhon, willy,
devset2 = ranjith, ben, smith

[/]
@pm = rw

[/project1]
@devset1 = rw

[/project2]
@devset2 = rw
@devset1 = r

8 ) Create WebDAV password file under /etc/apache2/

htpasswd2 -c /etc/apache2/dav_svn.passwd smith

htpasswd2 /etc/apache2/dav_svn.passwd jhon

htpasswd2 /etc/apache2/dav_svn.passwd ben

…

Please note that -c switch was used for the first time to create the file. Make sure that you don’t use this switch when add other members to the file.

That’s it, your new repository can be accessed from the following URL now,

http://svn./
