Misc Topics - Textbooks, Taxonomies, Barnes and Noble

Seth Godin on Textbooks
"Seth's Blog: Textbook rant" - http://sethgodin.typepad.com/seths_blog/2009/06/textbook-rant.html
A textbook author in Toronto made enough money from his calculus textbook to afford a $20 million house. This is absurd on its face. There's no serious insight or leap in pedagogy involved in writing a standard textbook. That's what makes it standard. It's hard, but it shouldn't make you a millionaire.

This industry deserves to die. It has extracted too much time and too much money and wasted too much potential. We can do better. A lot better.
As an aside, the Indian, low-priced, edition of Kotler's Principles of Marketing sells for some 85% less than its US edition price.




Amazon Categorization
I do not understand how Amazon.com does its taxonomy for books. Some categorizations just don't make any sense, and in some cases are just plain wrong.

Take a look at their books section, and browse to the section named 'Algorithms', or follow this path to get there: Any Category > Books > Computers & Internet > Programming > Algorithms. What you will find is that 6 of the top 7 bestselling books on ALGORITHMS are on Photoshop!!! While I am sure that Photoshop has many complicated algorithms that it uses, as it would need to, doing as it does are pretty amazing stuff with photographs, I don't think this is quite what a customer has in mind. In fact, the first book to have the word "algorithms" in its title is "Introduction to Algorithms", at #22.




Go figure.

Barnes and Noble Newsletter

Smart on the part of Barnes and Noble - to provide customers with the option of purchasing online or at a BN store and get the same discount.
You can use this link to get to the coupon page and print the coupons, one or all: http://www.barnesandnoble.com/email/Print_nonav.asp?r=1&PID=28929


If you can get people to try your product, maybe they will use it on a regular basis, and if they do so, maybe they will become regular customers. To incentivize customers, and to provide that slight 'nudge', an offer of a free Starbucks coffee at a BN store location is also thrown in.
Given that the app is free, and there is no purchase necessary to get the one "non-customized tall-sized Starbucks® freshly brewed coffee (hot or cold)", this is a bold and slightly desperate move, eh? Maybe not. Because, the offer is open to only Starbucks locations INSIDE Barnes and Noble stores. So, you already have the customer INSIDE the store. If he wants a free coffee, he has to download the app, and if he intends drinking that coffee inside the store, maybe he will check out the app while sipping his cuppa, find something that he likes, likes the discount offered, and use that to get the book from the store, right there and then. Assuming, of course, that the book is available in the store.

You have to show the cafe rep the app running on the iPhone though :-) Provided the BN Apple iPhone app has a decent interface and runs fast enough, this is, me thinks, a smart move.

Browse to http://www.barnesandnoble.com/iphone/index.asp?r=1 to get more information on the app.

When authors spar

When authors spar, it is usually good business, and good for business. Media happy. Sales up. Publishers happy. Authors happy. Customer entertained.

Chris Anderson, author of previous bestseller, Long Tail, The, Revised and Updated Edition: Why the Future of Business is Selling Less of More, is out with a new book, Free: The Future of a Radical Price,  (as an aside, he has been accused of plagiarism, i.e. reproduction without attribution, in his latest book: 'Free' plagiarism charge frames Internet content debate - Los Angeles Times, Wired Editor Apologizes for Copied Passages - NYTimes.com, What's Right and Wrong with Media Now - washingtonpost.com)

Malcolm Gladwell, author of bite-sized infotainers like Outliers: The Story of Success, Blink: The Power of Thinking Without Thinking, and The Tipping Point: How Little Things Can Make a Big Difference, takes exception in his review of the book, making some valid points in an article in the New Yorker, though not shying from taking provocative potshots too:
This is the kind of error that technological utopians make. They assume that their particular scientific revolution will wipe away all traces of its predecessors...

As Gordon Dean, Strauss’s predecessor at the A.E.C., wrote, “Even if coal were mined and distributed free to electric generating plants today, the reduction in your monthly electricity bill would amount to but twenty per cent, so great is the cost of the plant itself and the distribution system.”

You can read my review of "Outliers" at ...http://booksandphotos.blogspot.com/2009/03/outliers.html
Anderson retorts in a short article, selectively picking what he wants to pick on, "Dear Malcolm: Why So Threatened? | Epicenter | Wired.com", with a snarky intro:
But since journalist Malcolm Gladwell has somewhat parochially decided to make the Future of Paid Journalism the focus of his review of Free (which is, ironically, free on the New Yorker’s website; perhaps this is something Gladwell should take up with David Remnick?), I’ll try to respond in a bit more detail.
and a somewhat placatory one-liner:
Gladwell (who, by the way, I both like and admire, so let’s call this an intellectual debate between corporate cousins) writes:

Seth Godin, marketing guru and prolific blogger, joins the fray, "Seth's Blog: Malcolm is wrong", beginning what is one of his longest posts, with:
"I've never written those three words before, but he's never disagreed with Chris Anderson before, so there you go."


Paul Kedrosky also blogs about it at Malcolm Gladwell vs. Chris Anderson: Damn Technology Utopians

Colonel Bailey's Dungeon, Srirangapatna

Chained at the wrists to the wall, having to stand in waist deep water, cold water that is infested with leeches, in a dark dungeon that was hidden from most of the world. That is Colonel Bailey's Dungeon for you. If you visit Mysore, visit Srirangapatna. If you visit Srirangapatna (Wikitravel link), this is a must visit spot.

Ok - so what is Srirangapatna. Who is or who was Colonel Bailey. Why is there a dungeon named after him? And so on.

Let's see.
Srirangapatna is a historic town close to Mysore, some 19kms from the city of Mysore.
Srirangapatna is surrounded by the Cauvery river, and is thus really an island. In the centuries gone by, before dams had curtailed the vastness of the rivers, this would have afforded Srirangapatna a measure of safety from invaders. It takes time to cross a massive river you see. Srirangapatna is also the location of a millenium old temple, that I shall blog about in a future post.

Srirangapatna (link to Wikipedia page) was the capital of the kingdom ruled by Tipu Sultan and Hyder Ali.
Tipu Sultan did not get along well with the Englishmen, and fought several wars with them. After one such war, a number of English soldiers were imprisoned in this dungeon, including one Colonel Bailey, who died here in 1780.


View Larger Map (Colonel Bailey's Dungeon on Google Maps)





This slab above greets you at the entrance to the dungeon. It reads:
"In this dungeon were confined for many years the British officers taken prisoner by Tipu Sultan."

Enter past the gate, and to your left is the dungeon: a short flight of thirty odd steps needs to be descended before you get to the arches of the dungeon.



This is another view of the steps, seen from the opposite side.


The shoulder height stone slabs have holes in them, into which chains were attached that tied the captives to these slabs. The dungeon looks very clean, spic-and-span, because it has been cleaned up, the water drained out, and the walls painted. Which is a sort of a shame, because you are quite unable to visualize or imagine just what it would have looked like a couple of hundred years ago. No photographs (obviously), nor any paintings or artists' renderings of what the dungeon would have looked like then, so you have to use your imagination.


When the English laid siege to Srirangapatna, one of the canons fell through the ground and into the dungeon, and that is how the dungeon was discovered. Our good guide informed us that the cannon in the dungeon is not the actual cannon that fell, but a replica. I couldn't tell, either way.




These above are two photographs showing the canon that fell into the dungeon.

Now, the dungeon from above looks very nice, but our very helpful and informative guide informed us that much of this very neat work was done in preparation for a visit by Dr APJ Abdul Kalam, the then President of India.
This is how the site looks from the other side of the road - from the Cauvery river side.


According to http://wikimapia.org/307511/Colonel-Bailey-s-Dungeon:
The dungeon measures 30.5 metres X 12.2 metres and is built of brick and mortar. Prisoners were chained to stone slabs fixed on its walls. Named after Colonel Bailey who died here in 1780 A.D., this dungeon was used to imprison Captain Baird, Captain Rulay, Colonel Brithwite, Samson, Frazer and Lindsay by Tipu Sultan. During the seige of Srirangapatnam, one of the cannons rolled back, pierced the ceiling and fell into the dungeon. It is lying there still.

You can see the Cauvery river in this photo. Summer months mean the river is a pale shadow of its glorious self. Post-monsoon months should afford a much fuller view of the river.





The entrance to the dungeon: as you can see, you have to climb down a few steps to reach the dungeon.


The view from the dungeon looking up. As you can see, it is a dungeon, and therefore not at ground level, but several feet below. Some twenty feet or so below the ground level I would estimate. Unless you knew what you were looking for, and approximately where, in the centuries gone by, this would have been near impossible to locate.

Rajdhani restaurant at UB City Mall

Photos from the Rajdhani restaurant at the UB City Mall in Bangalore (my earlier post on the UB City Mall).
Weekday rates for a lunch buffet, and a buffet is all you get there, and a buffet is more than you can eat, are Rs 225 per person, inclusive of all taxes. Weekend rates are higher. Weekend wait times are also longer. If you get there around 1pm or so, expect to wait an hour or longer. After 2pm or so they even stop accepting people since the restaurant itself closes at 3pm or 3:30 pm.
The food is a mix of mostly Rajasthani and some Gujarati cuisine, and can be a bit spicy. The kadhi is delicious, as are almost all other items.


The toughest part is after they lay out the plate, with all the bowls, and before they start to serve all the food.

The plate fills up quite quickly, and gets emptied with almost equal speed.
 The other challenge of course was in waiting till the plate had filled so I could take the photos.

Junk Viz - Search

Search Engine Land has a post, Michael Jackson’s Death: An Inside Look At How Google, Yahoo, & Bing Handled An Extraordinary Day In Search, on how web traffic spiked at some of the web's leading properties like Google, Facebook, and Wikipedia, as a result of Michael Jackson's death.

All good and fine, and a sad day for fans of Michael Jackson, the king of pop as he was known as, but a sad day also for data visualizations.
The chart above is a time-series area graph, and you can see that on the 25th of June 2009, around 14:00 hours traffic to Google querying "Michael Jackson" or combination of words thereof, began to spike. But by how much? Where is the scale? What does each increment of the gridline indicate? 1 million searches? 10 million searches? 100 searches?
Secondly, the area chart could instead have been replaced with a line graph, thus minimizing non-data pixels.

The bar chart above does a better job, in that you can actually see what the vertical scale represents. However, there are at least three problems with this chart:
  1. The color scheme makes it tough to see the data clearly. Of course there are only two bars, so it is not that difficult.
  2. The X-axis labels are gibberish. There is no sub-title or explanation of what these numbers mean. What does "6.4k" mean? And what do the zeros at the end signify?
  3. The location of the vertical scale on the right is non-standard. Most often a scale is placed on the right edge when there are two axes on the graph, as in a dual-Y bar/line graph, and the left and right edges both have different scales. For example, if you were plotting sales and units on the same chart, and using the left axis for the sales and the right axis for the units data.
  4. Adding a fourth quibble: time series data is best visualized by a line graph.

 

A better graph than the first one, but with the same problems of having no vertical scale. But otherwise the best of the three examples.

Barnes and Noble Offers

From the Barnes & Noble weekly newsletter:

A 50% clearance sale on selected titles (in American parlance, called a "red dot" sale, which in turn has its provenance from brick-and-mortal store sales where items on sale would be often marked with a red dot, which was beneficial to retailers as well as customers):

Eat That Frog


Eat That Frog!: 21 Great Ways to Stop Procrastinating and Get More Done in Less Time

Short, fast-paced book on how to succeed by learning to prioritize, plan, and execute. Good solid advice in the beginning, but lots of contradictory pieces later on destroy credibility. A bit repetitive, no great motivational writing though. A list price of US $15.95 is steep for a book this short - 21 chapters of a thousand words (or so) each.

The secrets of success are really not that secret, nor complicated. The book serves to remind the reader that the secrets of success lie in being able to prioritize, plan, and execute upon your plans. To paraphrase a dialog from the movie "The Shawshank Redemption", 'get busy living, or get busy dying.' Some of the content is repetitive, worded differently, yet trying to drive the same point. This is not the definitive book to read on procrastination, and while there is good advice, especially in the first half of the book, the latter half contains some egregious contradictions that are very difficult to ignore and seriously undermine the credibility of the entire book. If at the end of the book you get the feeling that this book is only a pitch for author's personal coaching programs, you are not alone.

As Ram Charan and Larry Bossidy point out in their book, Execution: The Discipline of Getting Things Done, successful managers and leaders are those that execute on plans, not necessarily who come up with plans or grand visions. The "doers", not the "planners". A diffused sun warms. A focused sunbeam can burn through pretty much anything.

The book is full of good advice, aphorisms, one-liners and all. But. And there is always a but. The writing is not always consistent. There are few anecdotes in the book, and then wham!! there is a long one at the start of chapter 8. And then again a famine of anecdotes. The anecdote itself is too perfect and reads contrived to appear credible.

Then there are aphorisms that you may find difficult to accept at face value. Like "leap and the net will appear". Yes, you know that the author really means to say that you should have faith and confidence, and then take the action, but if your mind starts thinking, "yeah right! That could be one short leap into oblivion" or something similar it sort of destroys the aura of hope and motivation that the book is hoping to create.

Or "listen to audio programs in your car". Why?? Isn't that going to distract you from the task at hand - driving? Driver distraction is perhaps the leading cause of road accidents, and here the author is telling the reader to add one more distraction to their driving routine?!! Listening to an audio recording of a course is also a very passive exercise - the efficacy of such audio programs in actually teaching anything of lasting value is doubtful. Of course, such audio programs have worked very well for the makers of such programs, thank you, but learning has to be interactive to be effective - not unidirectional, passive, and requiring no more than a vegetative state of mind at best.

Some of the advice is contradictory - and while the reasonable person will realize that the advice is contextual, and one of many strategies for getting useful work done, it is still disconcerting to read in one chapter (Ch 18, "Slice and Dice The Task"):
Another technique you can use to get yourself going is called the "Swiss cheese" method of working. You use this technique to get yourself into gear by resolving to punch a hole in the task, like a hole in a block of Swiss cheese.
....
This may be as little as five or ten minutes, after which you will stop and do something else. You will just take one bite of your frog and then rest or do something else.
and in the very next chapter ("Create Large Chunks of Time") the author states:
Most of the really important work you do requires large chunks of unbroken time to complete. Your ability to carve out and use these blocks of high-value, highly productive time is central to your ability to make a significant contribution to your work and to your life.
...
Set aside thirty-, sixty- and ninety-minute time segments that you use to work on and complete important tasks.
and further on in the book (Ch 21 - "Single Handle Every Task"):
It has been estimated that the tendency to start and stop a task—to pick it up, put it down, and come back to it—can increase the time necessary to complete the task by as much as 500 percent.
Sir, Mr Tracy, dude - just what exactly do you want the now totally confused reader to do??? Swiss cheese, large chunks, single-handle - what??

The book cites Learned Optimism: How to Change Your Mind and Your Life - that seems to be interesting enough and well reviewed that it may be a good idea to go read **that** book instead.
It turns out that optimists have four special behaviors, all learned through practice and repetition.
  • First, optimists look for the good in every situation.
  • Second, optimists always seek the valuable lesson in every setback or difficulty. They believe that "difficulties come not to obstruct but to instruct."
  • Third, optimists always look for the solution to every problem.
  • Fourth, optimists think and talk continually about their goals.
Success is addictive, the author reminds us. Completing an important, big task successfully gives us a surge of energy and enthusiasm. Getting addictive (in a positive manner) to this surge can help create a cycle of success.

Chapter 2 talks about goal setting, and seven steps that serve as a formula for setting and achieving goals. Common-sensical, obvious goals, like "decide exactly what you want", "set a deadline", "take action on your plan immediately", and so on. But think about it just a little longer and you will realize that deciding what you want is easy enough to say, but to define exactly what you want is not so obvious. "I want to be rich" is easy enough. How? How do you become rich? Unless you were born rich chances are you are not betting on winning the lottery to become rich. Not that that is not a plan; it is just not a very good plan. You could steal - but that is likely to land you in jail, for a very long time. You could borrow money - but that won't make you rich, since you have to pay that money back. You could start a business, or become good at something, so good in fact that people pay you lots of money so that you do that something for them. Or you could become a writer, a musician, a photographer, an advertiser, a wrestler, something. But you have to define exactly what you want to do, and then how - not so easy now, is it?

Other excerpts from the book:
"Just find out what other successful people do and do the same things until you get the same results. Learn from the experts. Wow! What an idea."

"Especially, successful, happy, prosperous people use their time far, far better than the average person."

Successful people continually put the pressure on themselves to perform at high levels. Unsuccessful people have to be instructed and supervised and pressured by others.

"Your "frog" is your biggest, most important task, the one you are most likely to procrastinate on if you don't do something about it. It is also the one task that can have the greatest positive impact on your life and results at the moment."

"The first rule of frog eating is this: If you have to eat two frogs, eat the ugliest one first."

Remember that adage about measuring twice and cutting once, marking with a chalk and so on? Well, the author offers the same advice: "The good news is that every minute spent in planning saves as many as ten minutes in execution."

The law of Forced Efficiency says that "There is never enough time to do everything, but there is always enough time to do the most important thing."

A wage or a salary is a payment for a specific quality and quantity of work that can be combined with the work of others to create a product or service that customers are willing to pay for.
People have to be willing to pay for it. Does not matter how talented you are, how hard you work, how great the product is, if people are unwilling to pay for it, you are in trouble. The work you put in, how many other people can do the work that you are doing, how many people want the product you are working to build - all these have a direct bearing on the amount of money that you will make and be paid.
