Found a nice solution to the crazy external monitor problem in Fedora 15:
Download the latest release of ARandR from here:
Extract to some directory and navigate to that directory:

cd /arandr-0.1.5/

Run arandr.

./arandr

All external display problems SOLVED! Woohoo. Thank you, Christian Amsuess. You simply rock. I saw they are trying to get this nifty program reviewed to include it in the Fedora yum repository For such a wonderful program that replaces the crap they have in gnome 3, the brutal review process seems somewhat counterproductive.

---

The Extended monitor display works. However, if I assign the external monitor as the primary display, it doesn't work. It gives me a blank backlit screen. WHYYYY?

I really need one of these counters now.

The number matches. I have the exact expression too.

In addition, I feel like I could outshout the incredible hulk anytime after /var/log/messages records an exception that could have well read, "You wouldn't like me when I'm angry normal".

Even though there is now a driver in use (installed from here: ) I still cannot adjust my resolution. I didn't install nVidia's own driver because of this article:

There is only ONE resolution in the display settings (1024X768). Attaching an external monitor results in the computer shutting down on its own. And there is no way to adjust brightness.

Aarrgh. Frustration ++. I am just going to ignore this today. I have too much work piled up.

Getting information about package versions from Yum

Side note to (e:paul): R does pull in the following dependencies:

It's such a pity the packages it pulls are from 2007! :/

And Gnumeric doesn't even start up now. Something about:

• In Debian, you can actually, copy the entire /var/apt/cache files into a new installation and have the apt manager pull the .deb files from there without having to download packages over and over. But I don't see any such package repository in Fedora in the /var/cache/yum/ directory. It's all rolled into some sort of a database file. I found from this link that yum *deletes* everything after install. This is kind of wasteful for people who have enough space but not enough bandwidth(ME!). To prevent yum from deleting all the packages after install, apparently, I need to make keepcache=1 in /etc/yum.conf Now I only need to remember this detail next time.

Sometimes the simplicity of things across all distributions of linux are most refreshing. To burn an iso into a USB and create a bootable USB, I was glad to find out that I didn't need to hunt for programs as I usually do. I could do it in 4 steps.

---

(e:Paul) would like to remind everyone that this method completely gets rid of all the existing data on the USB drive so do it on an expendable one not somewhere you have all your backup files.

---

Pull up a terminal.
Pull up the system messages by

tail -f /var/log/messages

This records the realtime happenings on your system

Plug in your USB, you'll see it coming up on the messages window
Let's say its /dev/sdb

---

At this point (e:uncutsaniflush) would like to say:
You should also note that this only works if your usb drive is "/dev/sdb." If a box has multiple hard drives, it is unlikely that "/dev/sdb" would be your usb drive. If someone had for example two hard drives, "dev/sdb" would be the second one. And thus, all data on the second hard drive would be destroyed. "dd" is a wonderful tool but rather easy to misuse if one isn't absolutely clear which drive is which.

---

On the terminal again, umount it first

umount /dev/sdb

Go to the directory containing the iso image

cd /directory/that/contains/iso

Then give the simple command to burn the iso into the USB

dd if=file.iso of=/dev/sdb

This will take a while to finish, but yes, it's that simple.

The basic nature of sunlight indoors is that it is never direct most of the times. Almost all sunlight that filters through into rooms is reflected, diffuse and full spectrum (~5500 Kelvin). These three qualities set sunlight apart from artificial light.

The sunlight simulation lamps in the market are mainly high wattage, full spectrum and power consuming lamps. They are targeted at people with SAD - Seasonal Affective Disorders. While I am not convinced I have SAD and need the everyday intensive 1/2 hour to 1 hour therapy that these lamps are regularly recommended for, I am really interested in simulating sunlight at home especially when there is none outside.

I recently went to IKEA and saw this floor lamp, called "Tived".

The design is nothing spectacular. In fact, I would call it a bit ugly. But it has flexible arms that can be directed at various parts of the ceiling and walls. It looks like this flexibility could achieve that diffused reflected sunlight feel I want. I almost bought it but it comes with its own set of LED bulbs. I don't like that. I want to be able to readily replace the bulbs if they burn out. The only way to do this would be to get a lamp that holds regular full-spectrum CFLs. None of the more interesting IKEA lamps allow you to put your own bulbs in them.

If it had a few more flexible arms for some more bulbs and it took regular full-spectrum bulbs, it might come close to what I have in mind. IKEA also has a table lamp version of the "Tived" with more arms, but it could be tough to focus the light on the ceiling because of the lack of height. Even if I somehow succeeded in elevating the level of lamp, the bulbs are still the peculiar LED ones.

I wonder where I can get such a lamp. It would be so cool to have one this winter.

And I thought.

What is the meaning of life? Why are we here anyway? Banal questions and the themes of several works of literary merit (or not). But unanswered nevertheless. Where do we go after this life is over? Heaven and Hell and "the great consciousness" seem rather medieval with all this technology surrounding us. It's hard to believe that anyone even gets punished or rewarded for what they do in life here. That sounds like the words of an atheist. But I am not an atheist. I have a TON of faith. Perhaps not in religion, but in people themselves.

I sincerely believe Science cannot exist without this faith in people, in methods, in what we do, faith in our spirit as humans, faith in a better but unknown future, faith that our work is making things better, faith that we are finding meaning in our lives, faith that we will someday be in a better place and faith that we are making progress.

But in the middle of all this hope, what if some of us give out? Sink into death, into the unknown oblivion? Will anyone care? Yeah, maybe. If you are Steve Jobs, people might even cover the walls of the nearest Apple store with post-its. But what if you are not Steve Jobs? What if you are one of the millions who feel impelled to write one of those post-its? Will someone write post-its for you? How many post-its will you get when you leave this life of yours? Will they be enough to cover a wall? Does it even matter?

The pain you will give people by leaving them behind will matter. How will they cope with this pain? Will it be tough for them to see things you lived with when you were... well alive? Was your life so complicated that along with the pain, you leave them with the tough ordeal of going through the complications and the sheer volume of personal effects you lived with. That each little belonging collects the grief and plunges it back into them as they remember you and then realize that you are now gone?

I am not sure what the point of all these morbid musings are. But I don't want people to suffer after I am gone. I want them to know that I lived happily and tried to do my part. It doesn't matter whether I got anywhere or not. It just matters that I lived most moments happily. I don't want so many belongings that people drown in them and need to hold an estate sale because they don't want any of it. I don't want trivial stuffed toys, knick knacks, I don't want heavily highlighted books and notes with the dried flowers and leaves in them, I don't want anything remotely sentimental and pain-inducing. I don't even want a bed. It does sound pretty clinical and detached but I want to wrap up this life as cleanly as possible, as minimally as possible and when its time to leave, I want leave quietly and completely at ease, and smiling. Because I am not sure I know entirely what the meaning of all this existence is, I just don't think it's worth the drama and pain we bring to people when we let it all go.

And no, I am not sad. I just want to break this chain linux based whingeing that I have been indulging in for the past so many posts with some free-writing on a very non-specific stream of thoughts that just came over and needed written expression.

Woo Hoo!!

Why are the row and column numbers displaying as numeric placeholder skeletons in Gnumeric??



Does Gnumeric use some proprietary fonts that the mighty forces at Fedora have decided to outcast from the distro??

Aaargh. Can one thing be hitch-free for a change??! Apparently not.

Okay, NOW I have tried everything except OpenSuse.

Though Debian has been my favourite in terms of usability and friendliness, there is something really wrong with how Debian systems interact with R and deal with numerical ordering.

For eg. you would expect intervals to be ordered as:
[ 7,11)
[11,12)
[12,13)
[13,14)
[14,29]

Instead Debian orders them as:
[11,12)
[12,13)
[13,14)
[14,29]
[ 7,11)

In a scenario where I have one-digit, two-digit and three-digit numbers, I get the weirdest possible ordering. In the example above, it compares 1 and 7, rather than 11 and 7. This number-by-number evaluation creates serious problems in trend testing and determination of direction of association between variables. It potentially distorts the category that is treated as the reference variable. I looked at R documentation to see if I could change something to make it right. However, after many trials, my windows machine and machines running Fedora were uniformly giving me the right answers while Debian derivatives were giving me the weird answers.

For now, this is a dealbreaker for me and I can't go back to Debian.

That leaves me with
-- CentOS
-- Scientific Linux
-- Fedora
-- OpenSuse

I tried installing CentOS and Scientific Linux on the brawny Toshiba this past weekend but first there were problems with permissions and then problems with the R repository in both CentOS and Scientific Linux. Though Scientific Linux claims to come with R, the DVD I downloaded did not have R! When I tried to install R, there was no R in the default repository. Adding the correct R repository was an unending nightmare that took up 2 hours. I gave up in frustration. Then there was a problem with permissions. CentOS and Scientific Linux don't set up a username to go with the root password in the installation sequence. Even though you might have given a name to your computer during installation, you start up with something like:

yourgivenname@localhost.

instead of

yourgivenname@yourgivencomputername

In addition, it doesn't automatically add you to the sudoers group. I know linux admins won't view this as a problem but end-users like me don't need to work out details about how to add themselves to sudoers, change the localhost name, set up root permissions once more after installation. Its a pain to be burdened with all these nitty grittys even before you start using the system.

CentOS and Scientific Linux are so similar in their installation setup and behaviour, they might as well be clones of each other. The permissions and repositories problem rears its ugly head at every possible software installation. It gets to be very tiring. And what is with the repositories anyway??! They have software from 2 years ago! I understand they are more stable than the newer ones, but come on, newer features that make life easier in the software I use are very important to me!

So no more RHEL derivatives for me.

Which leaves me with Fedora. Sigh. I don't know if I can deal with all the mess that I have been documenting.

So at this point, I am thinking Suse Studio with the software I need from the list below. It could be better than getting OpenSuse and then installing everything because adding software and repositories beforehand might reduce dependency conflicts.

Things are not great in linux land. Maybe my particular combination of requirements breaks things? I can't believe it. This is my list of absolutely essential software for my linux machine. These are ones that I use on an hourly or a "minutely" basis.

Analyses Environment
- R
- RStudio
- Variable number of R packages

Spreadsheet
- Gnumeric

Writing Environment
- Texlive
- Texmaker Texstudio
- Texworks
- Gummi
- Geany
- Abiword: Yuck. Going to LibreOffice Writer. Compatibility is awful with MS Word.
- WriteType
- Zim desktop wiki
- LibreOffice Writer.

Networking
- Wireless
- Wired
- (Bluetooth would be nice, but seldom works, so I could let it go.)

Media
- Some hassle-free media player that would play multiple formats. Not liking Rhythmbox so much. I am done even risking any media formats on the Satellite P750 till the issues with the intel/nvidia cards are resolved.

Graphics
- Gimp
- Mypaint
- Pinta: This is just a pretty replica of paint.net. Clicking on the buttons doesn't do ANYTHING on Fedora 15.

... to be continued as I think of more things I use.

---

EDIT: Turns out I need WAAY more things that this puny list, so I decided to attached my latest yum log as a text file here.
Type:

sudo geany /var/log/yum.log

And you will get this log with date and time details of every package you have ever updated, installed or erased in Fedora 15.
