## Vanity Search Updated[edit]

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?

import urllib, re, pdb

user = 'Paddy3118'

site = 'http://www.rosettacode.org' nextpage = site + '/wiki/Special:Contributions/' + user nextpage_re = re.compile(

#r'<a href="([^"]+)" title="[^"]+" rel="next">older ' r'<a href="([^"]+)" title="[^"]+" rel="next"[^>]*>older ' )

newpages = [] pagecount = 0 while nextpage:

```
page = urllib.urlopen(nextpage)
pagecount +=1
nextpage =
for line in page:
if not nextpage:
# Search for URL to next page of results for download
nextpage_match = re.search(nextpage_re, line)
if nextpage_match:
nextpage = (site + nextpage_match.groups()[0]).replace('&', '&')
#print nextpage
npline=line
if '' in line:
# extract N page name from title
newpages.append(line.partition(' title="')[2].partition('"')[0])
page.close()
```

nontalk = [p for p in newpages if not ':' in p] nontalk.reverse()

print "User: %s has created %i new pages of which %i were not Talk: pages, from approx %i edits" % (

user, len(newpages), len(nontalk), pagecount*50 )

print "New pages created, in order, are:\n ", print "\n ".join(nontalk)

nextpage = site + '/w/index.php?title=Special:PopularPages'
nextpage_re = re.compile(

#r'<a href="([^"]+)" class="mw-nextlink">next ' r'<a href="([^"]+)"[^>]* class="mw-nextlink"[^>]*>next' )

data_re = re.compile(

r'^*))*title2rankviews[title] = [rank, views] rank += 1 page.close() print "\n\n Highest page Ranks for user pages:\n" fmt = " %-4s %-6s %-3s %s" # rank, views, +/- title print fmt % ('RANK', 'VIEWS', '+/-', 'TITLE') fmt = " %4s %6s %+3i %s" # rank, views, +/- title highrank = [title2rankviews.get(t,[99999, 0]) + [t] for t in nontalk] highrank.sort() for i,x in enumerate(highrank): rank, view, title = x movement = nontalk.index(title) - i print fmt % (rank, view, movement, title) </lang>

### Sample output on 12 July 2009[edit]

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.

User: Paddy3118 has created 63 new pages of which 31 were not Talk: pages, from approx 600 edits New pages created, in order, are: Spiral Monty Hall simulation Web Scraping Sequence of Non-squares Anagrams Max Licenses In Use One dimensional cellular automata Conway's Game of Life Data Munging Data Munging 2 Column Aligner Probabilistic Choice Knapsack Problem Yuletide Holiday Common number base formatting Octal Integer literals Command Line Interpreter First-class functions Y combinator Functional Composition Exceptions Through Nested Calls Look-and-say sequence Mutual Recursion Bulls and Cows Testing a Function Select Sort stability Moving Average Send an email Topological (dependency) sort Highest page Ranks for user pages: RANK VIEWS +/- TITLE 84 2792 +12 Knapsack Problem 100 2629 +0 Monty Hall simulation 107 2431 +5 Conway's Game of Life 132 2013 +1 Anagrams 199 1368 +2 One dimensional cellular automata 211 1233 -3 Web Scraping 218 1189 -1 Max Licenses In Use 221 1158 -7 Spiral 256 919 -5 Sequence of Non-squares 261 900 +4 Yuletide Holiday 267 866 +0 Column Aligner 281 809 +8 Y combinator 290 780 +6 First-class functions 303 732 -4 Data Munging 2 309 718 -6 Data Munging 315 706 -4 Probabilistic Choice 332 642 +1 Command Line Interpreter 351 598 +6 Mutual Recursion 365 568 +6 Bulls and Cows 366 566 +1 Functional Composition 388 501 -4 Integer literals 407 463 -7 Common number base formatting 418 436 +0 Look-and-say sequence 446 375 -8 Octal 455 347 -3 Exceptions Through Nested Calls 493 248 +2 Sort stability 525 207 -1 Testing a Function 548 186 -1 Select 559 174 +0 Moving Average 703 69 +0 Send an email 725 43 +0 Topological (dependency) sort

### Sample output on 24 July 2009[edit]

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:

### Sample output on 6 August 2009[edit]

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.

### Sample output on 29 August 2009[edit]

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.

Now if only I can discover the recipe and start some more, equally attractive pages...

### Sample output on 17 September 2009[edit]

Well, Ethiopian Multiplication is now the most popular page after the front page. Scary! (As I will need to live up to it).

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[edit]

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!

### Sample output on 23 January 2010[edit]

There are still five tasks in the top 100, although Monty Hall simulation has slipped backwards slightly.

The 24 game is still doing well - one to watch? As are the Evolutionary algorithm and 24 game Player.

I have just added Random number generator (included) today. I remembered past newsnet discussions on how the quality of RNG's could affect some simulations. It was important to know about the algorithms used so hence the task.

### Sample output on 10 March 2010[edit]

Did I really add all those tasks from Pangram checker to Knapsack problem/Unbounded/Python dynamic programming below?

The New your Times had a slight error in its story of Hofstadter-Conway $10,000 sequence that seemed to put finding a solution out of the reach of amateurs. Subsequent probing found that an RC task to find an answer would be feasible.

### Sample output on 15 May 2010[edit]

People seem to like the 24 Game, which is doing well on page views. The Luhn test is getting noticed, and I hope the same happens for the Number reversal game.

## ??[edit]

- Yeah, Ethiopian Multiplication is the most popular page for StumbleUpon landings, so every time we get a StumbleUpon surge, that page gets a boatload of hits. It's an amusing feedback loop. Any time someone thumbs-up any page on the rosettacode.org domain, SU throws more users at the pool of pages on that domain. EM appears to have the highest weight in that pool, so SU tends to throw more users at that page than any other. Since the Ethiopian Multiplication page has a rather high thumb-up frequency, that causes the domain weight
*and*the page weight to go up, resulting in a large surge of traffic. It's been exactly two weeks since the latest surge began, and it's still resisting falling back to normal levels; a normal day's SU referral visit count is 10-20, and we only just fell below 900 yesterday. Incidentally, I'm pretty sure I narrowed down the trigger behind this latest surge to one of your comments on another blog. Cool. :) --Michael Mol 01:38, 9 April 2010 (UTC)

- I can only sit back and watch in appreciation. (And occasional irritation; IIRC, between the last two server upgrades, one was triggered by a traffic flood you caused, and one by a traffic flood Kevin Reid caused. Not that I'm really complaining; it's nice being forced into a machine with a bit more elbow room. :) ) --Michael Mol 05:43, 9 April 2010 (UTC)
