Open Sans Pro and Source Sans Pro on CentOS/Fedora/RHEL

I generally find that the Open Sans family of fonts and the Adobe Source Sans Pro pleasing. And since I am the designated main typist in my office, creating eye-pleasing documents is part of the JD.

Download the Adobe Source Sans Pro here  and Open Sans here

Extract them and copy the extracted directories to /usr/share/fonts

E.g.

#cp -R Open_Sans/ /usr/share/fonts

Then run the refresh

#fc-cache

Or if you prefer reboot the computer to make use of the fonts.

Calibri and Cambria compatible fonts and Font Embedding in LibreOffice

LibreOffice being my primary productivity suite has never failed to amaze me with its usability and many features and updates from one version to the next.  I started using OpenOffice.org in 2000 and then move on to the go-oo fork and now the latest incarnation - LibreOffice suite.

For those of us who often exchange documents with people who uses MSO, a Calibri compatible but free to use font type would be Asap. Cambria would be the Droid Serif font.

Both fonts look gorgeous and if you are unsure that folks on the receiving end have your fonts - LibreOffice 4.1 (download here) now supports font embedding (Files -> Properties -> Fonts tab)  so that your document would not look weird when you use Font A to compose your docs but the receiver hasn't Font A but uses something else closest to replace the font - which in reality isn't really good enough.

Kudos to the devs and volunteers who contributed to LibreOffice and the equally impressive (and I would say, prettier) Apache OpenOffice.

The often overlooked Seamonkey

I am very happy with my work lappy running CentOS 6.4 - I never need to worry about the next update borking my system.

Unfortunately, the supplied Firefox browser doesn't work too well with my personal banking site. Previously this was unimportant as I always had Google Chrome to fall back on; sadly Google decided not to support Chrome on the CentOS/RHEL platforms.

Would hate to trade the rock solid reliability of CentOS with Fedora - so it hit me why not Seamonkey?

With the EPEL repo added and a yum install seamonkey later, the latest Seamonkey is installed on my lappy - it is actually the same version that is on the Seamonkey site. Nothing to shout about on the looks, in fact being the "old guy" I am - the theme kinda brings me back....ah well...personal banking site....and wallah it works perfectly!! Yay....

Now back to work....

Enabling Broadcom 4313 Wireless support and VLC installation on RHEL 6x/CentOS 6x

CentOS is an excellent desktop OS for the discerning user who wants rock solid performance without paying a premium.  However, since it is built from server source with some desktop apps and bits thrown in, stability comes at the cost of the latest and greatest version of the software bundled. For instance LibreOffice is still stuck at 3.4x, it's Pidgin instead of Empathy and there are no versions of Banshee available.

However, having lesser things to play actually makes it an attractive choice for focussing on getting work done since there are practically no games available but there is a plethora of "boring" server stuff that can only make a geek quiver with delight!   

Since I work in a RH shop, having a RHEL server installed on my notebook actually makes sense, but then I would have to "burn" through one subscription for no good reason. So CentOS it is then. 

Two problems come into mind - the Broadcom wireless (BCM4313) on my notebook wouldn't work with CentOS or RHEL and two, the lack of multimedia codecs would ensure that my notebook would be good for work and staging and precious little else. That wouldn't do since I live off my notebook. 

After trawling through the web, I managed to resolve my #1 problem and easily resolve issue #2. 

Preparing the repos

# rpm -ivh http://ftp.riken.jp/Linux/fedora/epel/6/i386/epel-release-6-8.noarch.rpm
# rpm -ivh http://download1.rpmfusion.org/free/el/updates/6/i386/rpmfusion-free-release-6-1.noarch.rpm
# rpm -ivh http://download1.rpmfusion.org/nonfree/el/updates/6/i386/rpmfusion-nonfree-release-6-1.noarch.rpm
# rpm -ivh http://rpms.famillecollet.com/enterprise/remi-release-6.rpm
# rpm -ivh http://elrepo.org/elrepo-release-6-5.el6.elrepo.noarch.rpm

Enabling Broadcom Wireless Support
The Broadcom driver doesn't come in a binary form due to licensing restrictions. To enable Broadcom 4313 support, we need to compile the driver from a Source RPM.

Install the required dependencies

As root:

# yum -y groupinstall 'Development Tools' 
# yum -y install redhat-lsb 
# yum -y kernel-devel-$(uname -r)

Preparing for compilation

Choose the right architecture archive (32 or 64-bit) and download the source RPM from (http://elrepo.org/linux/elrepo/el6/SRPMS/wl-kmod-5_100_82_112-9.el6.elrepo.nosrc.rpm) to anywhere (e.g. Downloads) and the driver archive from Broadcom's site (http://www.broadcom.com/support/802.11/linux_sta.php) to ~/rpmbuild/SOURCES/

As normal user:

$ mkdir -p ~/rpmbuild/{BUILD,RPMS,SPECS,SOURCES,SRPMS}
$ echo -e "%_topdir $(echo $HOME)/rpmbuild\n%dist .el$(lsb_release -s -r|cut -d"." -f1).local" >> ~/.rpmmacros


Building the Source RPM

As normal user:

$ rpmbuild --rebuild --define 'packager <user name>' /home/<user name>/Downloads/wl-kmod*nosrc.rpm


Installing the Compiled RPM

As root:

# rpm -ivh /home/ericyeoh/rpmbuild/RPMS/x86_64/kmod-wl*.rpm



Remove unused services

As root:


# modprobe -r b43 b43legacy ssb wl lib80211

# modprobe -r bcma (for RHEL/Centos 6.4 and above)
# modprobe lib80211_crypt_tkip
# modprobe -r wl 


Reboot and it's good to go.

Remember to remove any instance of ndiswarpper if it's installed. 

Installing VLC
VLC is an all in one media player for the many MP3s and movies I have. VLC is one of those indispensable "if-you-are-stuck-on-a-desert-island" software. 

As root:

# yum --enablerepo=remi-test install vlc

HP LaserJet P1005 on Fedora 17

A year ago I got myself a cheapo HP LaserJet P1005 printer. The price was right and it worked well with my openSUSE 11.4 (after some titanic struggles) desktop and Ubuntu 10x notebook then. Fast forward to the end of 2012, post apocalypse; and the printer was starting to gather dust at home and not wanting it to be the nesting grounds for ants, roaches and other nasties, I decided to bring it to work - as a temp printer (the office's primary printer has lapsed into deep coma) for the tech department.

My work desktop (also from home) is running Stella Linux, a respin of the venerable CentOS with all the nice multimedia bits with my primary lappy and on Fedora 17, as with the rest of the techies.

I was ready for some titanic struggles as I did with my desktop's previous openSUSE host; so with sleeves folded up and skipping lunch - me ready. Alas, after 5 minutes of Googling I found this page which directed me to the HP Linux Printing and Imaging page my anticipated struggle was resolved within 10 minutes.

Got my desktop's CUPS setup and firewalls opened for 631 TCP/UDP, enabled remote access to my CUPS server and shared printer.

All is working now.

Let the tree killing begin!!!

Roboto Fonts

The Roboto set of fonts used in the Android Ice Cream Sandwich platform can now be downloaded from http://developer.android.com/design/style/typography.html

For GNU/Linux, just download the file, unzip it, create a dir in /usr/share/fonts/, copy *.ttf to that dir and then just run fc-cache and you are good to go.

Enjoy.

New Font Repo for openSUSE

Adding fonts is pretty easy in openSUSE (and in GNU/Linux) generally - create a dir in /usr/share/fonts dump your ttfs in it run fc-cache or SuSEconfig (under openSUSE or SLE)and you are done.

However having a repo of about a hundred fonts that can be added from Yast is just heaven sent. Add the repo and refresh it:

zypper ar -f http://download.opensuse.org/repositories/M17N/openSUSE_12.1/ Fonts

zypper ref Fonts

And you are good to go.

It also has support for openSUSE 11.4, Tumbleweed, SLE 11 and Factory.
