    - by swalkner
    Hi all, I want to use Flurry to collect some statistics, so I registered and created an app in Flurry. Then, I put the following code in my appDidFinishLaunching: [FlurryAPI startSession:@"code here"]; Afterwards, I installed the app on my iPhone and ran it - but I don't see any data online. Am I missing something? And is data also collected from the simulator? Thanks a lot, Stefan

  • 'Similarity' in Data Mining

    - by Shailesh Tainwala
    In the field of Data Mining, is there a specific sub-discipline called 'Similarity'? If yes, what does it deal with. Any examples, links, references will be helpful. Also, being new to the field, I would like the community opinion on how closely related Data Mining and Artificial Intelligence are. Are they synonyms, is one the subset of the other? Thanks in advance for sharing your knowledge.

  • Django: How can I protect against concurrent modification of data base entries

    - by Ber
    If there a way to protect against concurrent modifications of the same data base entry by two or more users? It would be acceptable to show an error message to the user performing the second commit/save operation, but data should not be silently overwritten. I think locking the entry is not an option, as a user might use the "Back" button or simply close his browser, leaving the lock for ever.

  • How to pick a chunksize for python multiprocessing with large datasets

    - by Sandro
    I am attempting to to use python to gain some performance on a task that can be highly parallelized using http://docs.python.org/library/multiprocessing. When looking at their library they say to use chunk size for very long iterables. Now, my iterable is not long, one of the dicts that it contains is huge: ~100000 entries, with tuples as keys and numpy arrays for values. How would I set the chunksize to handle this and how can I transfer this data quickly? Thank you.

  • datagridview rowsremoved event gets called every time data loads

    - by Nilotpal Das
    The datagridview rowsremoved event gets called every time the data gets loaded. It also makes sense to a certain extent that every time the data loads, the existing rows are removed. so technically the event should get called. But how do i differenciate that from the actual delete button getting pressed. I don't think the key events should be used, that wouldn't be a clean approach. Any help will be most appreciated.

  • Microformat combination to use with events data on a map

    - by Dave Taylor
    I have event data displaying on a map and I am currently using the geo microformat alongside it however it's not particularly rich to have just a list of locations without any details of what they correspond to. I've been looking at combining microformats to achieve this and looking for some thoughts on the subject here is the data i am marking up: event title, event location [latlong], event address, contact phone, link to full details My initial thoughts are to use an hCard along with geo? Is there anything better? Thanks in advance

  • Lisp data security/validation

    - by Wayne Werner
    This is really just a conceptual question for me at this point. In Lisp, programs are data and data are programs. The REPL does exactly that - reads and then evaluates. So how does one go about getting input from the user in a secure way? Obviously it's possible - I mean viaweb - now Yahoo!Stores is pretty secure, so how is it done?

    - by Rob Young
    Has anyone written a YQL open data table for accessing Wikipedia? I've had a hunt around the internet and found mention of people using YQL for extracting various bits of information from Wikipedia pages such as microformats, links or content but I haven't been able to find an open data table that ties it all together.

  • Dump Microsoft SQL Server database to an SQL script

    - by Matt Sheppard
    Is there any way to export a Microsoft SQL Server database to an sql script? I'm looking for something which behaves similarly to mysqldump, taking a database name, and producing a single script which will recreate all the tables, stored procedures, reinsert all the data etc. I've seen http://vyaskn.tripod.com/code.htm#inserts, but I ideally want something to recreate everything (not just the data) which works in a single step to produce the final script.

  • OleDB Jet - Float issues in reading excel data

    - by Patrick
    When I read a sheet into a DataTable using the OleDbDataReader, floating point numbers loose their precision. I tried forcing OleDb to read the excel data as string, but although the data is now contained in a DataRow with each Column defined as System.String it looses precision (18.125 - 18.124962832). Any idea how to avoid this behaviour?
