digitalmars.D.announce - TDPL Amazon rank at 4-months high

reply Andrei Alexandrescu <SeeWebsiteForEmail erdani.org> writes:
Hello,


I've been witnessing a recent increase in interest in TDPL, which can be 
assumed to be a good proxy for interest in the language itself. The 
trend has been bucking for about 45 days now and is reflected in higher 
click-through rate on related ads and in a better Amazon sales rank.

Today TDPL's Amazon rank has reached 24,896 (currently at 29,285; 
updated hourly), which is a 4-months high. (By high I actually mean 
small because lower rank is better.) Last time a better rank was reached 
was on October 29, 2010 (18,755).

Amazon dynamically assigns unique sale ranks to all of its books such 
that 1 is the best seller and 8M is the least sold. Rank below 1,000 
indicates a bestseller, below 10,000 means an excellent seller, and 
below 100,000 means a good seller. (Amazon's ranking system handles 
these tiers differently.) The sales rank of "good sellers" may fluctuate 
a lot so it needs smoothing by a moving average (for example TDPL's rank 
only on Feb 2 was 347,125).

For a rough comparison, here's the current sales rank for two comparable 
books: Erlang - 129,001, Head First Java - 977. The latter book is the 
best selling comparable book.

Yah, perhaps sales aren't that strong after all :o). Andrei

You mean that, as the author, you don't even get to know how many copies sold? o_O

Perhaps they reprinted with "the fault" in order to milk the "limited edition" factor?

No.
 And remember the "best seller rank" is regionally dependent, i.e.
 different Amazon servers will deliver different results.

 There is also historical hysteresis to their figure:  my "Developing
 Java Software" second edition still rates higher than the third edition
 even though the publisher reports the third edition has sold the same
 number of copies -- which is actually quite a lot thankfully.

Forgive my ignorance - I didn't know you have a book portfolio, and so impressive at that. Congratulations! Yah, there are many variables. Add to those many handling details that influence the process. TDPL has certainly sold more than 1830 copies by now (= the collector's edition count) but booksellers have no obligation to send older prints first, so it all depends on which batch they have handy when shipping. Also I'm sure some smaller booksellers have gotten a batch from the collector's edition that hasn't been sold yet. Andrei

It could be like milk. You buy a new carton of milk, and shove it in the refrigerator. When you need some, you grab the carton in front, which is the new one. So the old milk remains "in stock" for months, years, ...

milk + years = poison :-) To solve this, somebody invented FIFO (first in, first out), and FILO (first in, last out), to solve storage problems.

You'd need a fridge with two doors: one in the front, one in the back. Insert new food in the front, get food to eat from the back (or the other way round). But reinsert opened food in the back (or, in the alternative case, in the front). ;-)

Cleaning out what's in the back of the fridge is always a terrifying experience.

I think grocery stores sometimes have fridge cases that. Alton Brown has a fridge on the Good Eats set that his crew hacked up that way for "fridge POV" shots and for "The Lady of The Refrigerator".

Well, at first. But there were only about 1000 non-limited ones, weren't there? They have to run out eventually. I've seen both limited and non-limited, so they're both out there, but the longer that the book has been out, the less likely it is to get one of the "limited edition" ones. I would have thought that it had been out long enough that that would be the case, but maybe not. Of course, it wouldn't be all that hard for there to be a number of limited editions in a particular warehouse that just hasn't shipped as many as elsewhere, and if you happen to get one shipped from there you get a limited edition whereas pretty much everywhere else has the normal ones now. Most of the people around here are likely to have the limited ones though (regardless of what is normal in general), simply because we generally picked up the book as soon is it came out. - Jonathan M Davis
