So in two weeks I've created two new tasks, and the Knapsack Problem has finally moved to become my top viewed task.

I have added no new pages, but I have broken into the top 100 list of page views!!:

I did like writing the story around that Knapsack task.
Vanity Search Updated
After the 4th of July RC updates, My RC Vanity Searcher needed to be updated due to HTML changes. I decided to add a modification, that shows the movement between the order a page was created in, vs the max views order called +/-.
<lang python> Rosetta Code Vanity search:
How many new pages has someone created?

Since the 25th of June I've added two tasks: 'Send an email' and 'Topological (dependency) sort'.
With the new +/- column showing views w.r.t. creation order, you can see that the Knapsack Problem has captured the readers imagination. The Y combinator has a strong showing too.
Is it possible to get views in the last three months rather than total views? That would allow me to discount some of the bias due to date created.

What has happened in the last twelve days?
- Ethiopian Multiplication is newly added and is off to a great start. Editors seem attracted to the challenge. I decided to add this as I was drawn by the simplicity of the algorithm. To make it a better RC task I decided on the restriction that you must create the function using a functions to half, double, and test for even-ness.
- I guess viewers are tired of yet another sort: Topological (dependency) sort still languishes at the bottom.
- I created my first #REDIRECT page: Russian Peasant Multiplication
- Knapsack Problem still continues its rise in ranking (thank you).
- At the top of my table, everything above Sequence of Non-squares has improved its rank. I tried to think of some other thing thats links them, but nothing special comes to mind.
- I am not sure if spiral is unpopular, as it has a lot of views, was my first page ever, but appears seven places down from its original top spot - I remember writing it after creating the Python solution to Zig Zag.
Here's the table:

So, what's been moving!
Well I am glad to see that I have to go right down to Sort stability before I see a task that is lower in the rankings than last time. Y combinator has leap-frogged even more of my tasks, from +8 to +11; and Bulls and Cows, and Ethiopian Multiplication are also doing well.
Newly created is First-class Numbers. When reviewing wp:First-class function, There were comments in the talk page about what languages really have FcF. I decided that rather than bring the discussion to RC, I would create a sister task - similar but using numbers and asking examples to compare the numbers solution with the functions solution. I guess people can still get around it, but I hope they follow the spirit of the task.

The big change that warrants its own section below, is that Ethiopian Multiplication is at the head off the list of pages I started, and ranked number three on RC as a whole.

I still like the explanation of the knapsack problem after all these months, so its nice to see it doing well.

Sample output on 02 December 2009
There are now five tasks in the top 100.
The 24 game is doing well, which is good because my kids and I like playing the game.
I have just added Hamming numbers today. I blogged about it this weekend, then someone asked for an RC task - which I had planned to do, so things worked out well!

Poly thanks
Thanks but if you needed you see the example to get it clearer... it means the pseudocode is not too much clear:D More over, implemeting Octave solution, I've discovered it's more convenient to keep the higher power first (in the "vectors"), so likely I am going to rewrite the pseudocode ;) ... --ShinTakezou 16:31, 18 June 2009 (UTC)
Ethiopian Multiplication
Chalk one up to your vanity search; Ethiopian Multiplication has been the single biggest landing page for Sunday and Monday this week. There's been a huge influx of traffic to it via StumbleUpon. --Short Circuit 02:13, 25 August 2009 (UTC)
- Yah!! (I hope the traffic is OK on your servers though)?
- Lets hope some stay for a browse around the whole site... --Paddy3118 03:48, 25 August 2009 (UTC)
- According to the analytics the bounce rate for stumbleupon referrals for the last three days is about 70%. So some did stay to look around. --Mwn3d 18:32, 25 August 2009 (UTC)
It is great that people are staying to look around, but I am puzzled? I can't find what is sending people to the Ethiopian Multiplication page on the Web. Any links? --Paddy3118 18:21, 26 August 2009 (UTC)
- http://www.stumbleupon.com/url/rosettacode.org/wiki/Ethiopian_Multiplication --Mwn3d 18:22, 26 August 2009 (UTC)
- That one mention means so many hits? Wow. I thought only /. and reddit had that kind of affect. --Paddy3118 18:48, 26 August 2009 (UTC)
- Well that link is from a while ago. Someone else must have found it and put a link to that SU link somewhere else. I'm not sure how to figure out where though. --Mwn3d 18:56, 26 August 2009 (UTC)
- It wasn't slashdot, digg or front-page-reddit level. Those would have resulted in tens of thousands of visits over a day. Peak traffic so far was Monday, where Google Analytics claims as much as 7.7 page views per minute. (Which is actually a bit off, as GA won't register raw, json or css page requests, so the requests would have been much more clumped, or bot edits, which it wouldn't see at all.) There were 368% more visits Monday(3,768) than the previous Monday(804). Each visit monday averaged 1.79 pages/visit, while the previous Monday averaged 3.56. These wouldn't be hard loads for most setups, but we've been riding close to the limits of the Slice under bursty loads for quite a while. I've got an offer to be pretty much the sole occupant of a 4-core Xeon box with 16GB of RAM, but It'll be a gradual transition, if it goes through at all; I won't have root, and I'm uncertain about the current admin's reaction time. Otherwise, I need to find an income source for RC. My number one desire would be to sell content-derived books, but selling t-shirts and the like, even at $5 markup each, would easily make the site pay for itself as it currently sits; Five t-shirts a month would do it. The next most likely option is a donation link, but I hate asking for handouts. And I hate banner ads even more. --Short Circuit 21:22, 26 August 2009 (UTC)

Um... I have just seen one of the last pages I created jump to the HEAD of my vanity list, and by a huge margin! After seeing the figures (below), I'm gob-smacked!

Strange?
Ethiopian Multiplication jumps to be the most popular page behind the Main Page, and I can find no evidence of a 'buzz' around it. No blog entries, no group discussions. I would have expected something more? --Paddy3118 06:55, 1 September 2009 (UTC)
- It's all coming through StumbleUpon. I'd like to write a blog post on exactly what I think happened, but it's going to take a while, and I need to look into it more. A simplified explanation would be that a SU user discovered the page, liked it or reviewed it, leading to both his subscribers (and their subscribers) to see it, as well as increasing the page's general ranking in SU's page selection algorithm. This would be made easier to show if I could identify a trend around the phrase "ethiopian multiplication" in blogs and searches over the last month. The functionality is there in Google's advanced search, but it requires time and opportunity. --Short Circuit 14:33, 1 September 2009 (UTC)
Evolutionary algorithm
I've had the dreaded Flu the past week, and am still getting over it. To test my faculties I took a look at what tasks were requested and took on Weasel algorithm.
I wasn't quite happy with the results, and wrote that up in a blog entry. One of the commenters there, (thanks Steve), used the phrase 'evolutionary algorithm', which turned out to fit a WP page, that re-introduced me to all the proper nomenclature. I decided that a re-write using the proper terms, would then make a better RC task.
I tried to word the RC task so that people could experiment and slot in different algorithms for things like the fitness and mutation functions and I'm pleased to see that already the C language solution has done just that. (I do like the way the C is coded too; very nice).
After the coding, what gets me is the amount of controversy that was caused by such programs, especially the original quoted in a book by Richard Dawkins (that I have not read). It seems so little to be controversial about, but then I guess RD's delivery might inflame some.

Sorting Using a Custom Comparator - C# incorrect
By that measure, the ADA solution would also be incorrect? Sorting Using a Custom Comparator#Custom_Comparator.adb
- Thanks, I've tried to point that out now. --Paddy3118 06:45, 20 November 2009 (UTC)
