Wachet auf, ruft uns die stimme

I am re-discovering all of Bach magnificent Cantatas once more and BWV140 is one of my all-time favourites.

I love the absolutely perfect build up of the vocal ornamentations to the crescendo of the choir from 4:26. Hearing the cantatas is almost equivalent to getting a virtual pair of wings if you close your eyes.

Did you know that Bach wrote a brand new cantata every single week for the Sunday worship service, and that there are nearly 260 of them? Prolific was a gross understatement when it came to Bach.

djvu files in Fedora

Evince has djvu file support but just not in Fedora, at least by default.

You need the evince-djvu module to make Evince launch djvu files:

sudo yum install evince-djvu

The Emperor's Waltz

The Waltz is my most favourite kind of classical music after sonorous abstract cello recitals and baroque orchestral works. Wait till you reach around 3:20, when they give the dance a modern interpretation. :)

United States of Obesity


Though I like the poster below for how it presents information, I think all of us need to review this really informative book on reality and myths surrounding Obesity: directly leads to the PDF.
Source: Center for Consumer Freedom (CCF)

The book has some excellent data presentation - far prettier than the poster below. A pity, its locked into PDF. I am going to see if I rip those diagrams and also put it on this post in direct contrast to the pretty poster in my original post.

For me, the real challenge is to examine if I am cherry-picking results or have done a balanced survey of the peer-reviewed literature. I am currently disinclined to accept any pigeonholed set of beliefs on the many sides of this whole obesity discussion. In many ways, I see more confounders in the equation than is comfortably explained away. If there is an epidemic that needs immediate addressing, its one of confusion and indecision.

And now my original post:

Just saw this here:

Now, that is classy presentation. Twenty years back, I would have been a 4 instead of being relegated to 2s and 0s most arbitrarily.

The real sources
I posted this because I find the data presentation in this poster very compelling. It is capable of eliciting a strong response from everyone just because it is so directly and simply presented. However, you have raised some concerns over the source of the chart. So I dug more and came up with the real sources of this compilation:
  • The portion size statistics and graphics came from the National Heart Lung and Blood Institute's (NHLBI) website. They have 2 full slide sets for post and present portion sizes:
  • Set 1:
  • Set 2:
  • The BMI chart was adapted from the NHLBI's evidence report titled: "Clinical guidelines on the identification, evaluation and treatment of overweight and obesity in Adults. The evidence report." Available at:
  • The facts for the diagram came from here:

I am also going to keep adding equivalent data presentations from non-commercial sources to this post.
Source: RAND health, an offshoot of the famous RAND Corporation, a non profit think tank whose name expands to just Research And Development
Data from Sturm, R., J. Ringel, and T. Andreyeva, "Increasing Obesity Rates and Disability Trends," Health Affairs, Vol. 23, No. 2, March/April 2004, pp. 1–7.

Food subsidies and the food pyramid
{Re: (e:heidi)'s observation. Last para Comment #66257}
From PCRM. Physicians Comittee for Responsible Medicine

Note that the government recommended food guide pyramid is now a plate with %s. I personally think it makes more sense and is more comprehensible even though the new food plate also has its critics. An argument is that the government shouldn't be telling us what to eat. However, people who determine the food pyramid or the plate are just scientists working for the government. This diagram raises the real parallel question for me, why are these scientists who come up with food portion recommendations not on the committees that decide on what to subsidize?!
And just for fun, from Apples From Oranges:

Oh no! Something has gone wrong

You have to hand it to the Gnome3 folks. At least the message looks crisp and smart.


Even though what followed was an undeniably ungraceful crash.

All the pretty horses

sounds very much like all the running processes. Well, it does if you slur and clip the last sss.

All the running processes

ps aux | less

  • gives you the full command or name of the process, which you can then use to create keyboard shortcuts or just kill processes with their PID numbers
  • piping the ps aux to less makes the display not run amok on your screen and you can scroll the output with your keyboard

All the processes run by you

ps -u username

  • drawback is it doesn't give you the full command

Grepping for particular process.

ps aux | grep screen

  • simple, you pipe the ps aux through grep.
  • in the example above I was trying to search for what the screenshot utility was called. The output is below:

[user@comp ~]$ ps aux | grep screen
user 1527 0.0 0.1 429476 11664 ? Sl Nov14 0:11 gnome-screensaver
user 19804 0.0 0.1 415516 12696 ? Sl 07:54 0:00 gnome-screenshot --interactive
user 20066 0.0 0.0 109112 840 pts/0 S+ 08:07 0:00 grep --color=auto screen

The bolded text is what I was searching for.

How to find the internal commands of the processes/programs/applications in linux. Can use these commands to assign keyboard shortcuts. Can use process IDs to kill applications/programs

Buffalo General has a rooftop disco.

Or so it seems today.

l stare at this building everyday and I couldn't help but notice that they added another beacon light on its rooftop. It's almost like a discotheque now.


If you can't clearly see the gaudy three lights in the super crappy picture that my phone has taken, the new light starts off as yellow, slowly turns a dark bright orange and then dims to a low green. The older two lights were red and yellow. That's quite a spectrum there.

Did they receive complaints from the pilots of random helicopters that keep zooming around the place? Or maybe they are jazzing it up for thanksgiving. Or maybe its an alien spaceship sending signals that Buffalo is safe for landing?

Arrgh. Google Bookmarks Lists

Back when Google introduced the Google Bookmarks Lists, I should not have jumped at it.

But I did. BIG mistake. Now ALL my zillion bookmarks are stuck in lists without ANY way of exporting them anywhere. The export-bookmarks function only works for bookmarks that are NOT in lists.

This is so annoying. I hate you, Google Bookmarks List makers. Haven't you ever heard of the data liberation front, your company's own sister concern????

Biological Science Journals need a reality check

I read this article today (poorly written and not very informative. Don't bother reading).

Tchantchaleishvili V, Schmitto JD. Preparing a scientific manuscript in Linux: Today's possibilities and limitations. BMC research notes. 2011 Oct;4(1):434+. Available from: .

The table at the very end summarizes the format in which top biological sciences journals prefer to receive submissions.

  • New England Journal of Medicine(34) PDF*, DOC, WPD, TXT, RTF
  • Cell(37) DOC, RTF, TXT
  • The Lancet(38) DOC
  • JAMA(39) DOC, WPD
  • The Journal of Biological Chemistry(35) PDF***
  • Circulation(40) DOC, WPD
  • ===
  • Nature(29) DOC, TEX**
  • Science(30) DOC, TEX**, RTF*
  • PloS ONE(31) DOC, TEX, RTF
  • PNAS(32) DOC, RTF, TEX
  • BMC Journals (33) DOC, RTF, TEX

[* Some restrictions apply]
[** TEX files must be accompanied by a PDF version of the same text for visual reference 19 ]
[*** Although manuscripts must be submitted in PDF format, Microsoft Word is recommended to prepare the manuscript text]

Look at the sheer proliferation of M$hit formats on that list. The 1st preference is always doc. Wherever PDF is accepted, M$hit is recommended to make that PDF.

Even if you want to change *they* will not let you.

Am I in the wrong field or what? Nevermind content, even submission guidelines are so proprietary, backwards-thinking and insular.

Undo any last action in Linux?

Sometimes, I accidentally move files into folders. However, I am uncertain what files I moved (because I wasn't paying attention when my stylus accidentally dragged and dropped that file into some nearby folder). So I know that something has changed in the directory but I am not sure about what has changed. In windows, I could easily right click and undo whatever the last action was - rename/delete/move. Where is this undo functionality in Linux??

If there isn't a way, is there at least a log that logs all these events so I could check it and see what was changed?

Am I missing some obvious way to do this? Ctrl-Z does not cut it.
