  • What are the algorithms that are used for working with large data in popular web applications

    - by Moss Farmer
    I am looking for some well known algorithms that can be considered while handling very large amount of data.(Edit- By large amount of data I refer to records in a database excluding blobs). These algorithms if not in totality but in parts may be used in big web applications like Twitter, Last.fm , Amazon ,etc. Specifically, I'm looking for names or links to such algorithms. My primary interest lies in developing a very deep understanding on working with large database records and writing efficient code for working with the same.

  • Aggregating customer service emails from multiple ecommerce sites for easy handling

    - by nitbuntu
    For one of my main customer help email addresses I use Mozilla Thunderbird with a combination of tags and saved searches. As the number of my e-commerce sites grows from 1 to more, customer service handling gets more tricky. Is there any simple and efficient way of handling emails from the different sites? Perhaps what I'm looking for is a way of aggregating customer service emails from different sites, into one place? Perhaps there's a way of already doing this within Thunderbird or Gmail?

  • Kickoff and Krunner to search with less than 3 chars in search field?

    - by Benjamin
    Both Krunner and Kickoff in Kubuntu return a list of found items after the user has entered at least three characters in the search field. Usage on Synapse shows that returning a list after one character onwards is faster and efficient. I would like Kickoff and Krunner to behave similarly, by making the return a list of items after entering the first character in their search field. How can I achieve that?

  • What are known approaches to graphing algebraic expressions?

    - by jeremynealbrown
    I am planning to build an expression parser that will be used to graph algebraic functions ( think TI-83 ) with JavaScript. Functions will take the form of f(x)= Aside from typical operators such as: + - * / ^ I'd also like to add support for inline functions such as: sin(), cos(), log() and random(). I have looked at implementing the Shunting Yard algorithm for parsing expressions, but it does not look like an efficient approach to evaluating a function with a hundreds or thousands of inputs. What other known algorithms exist for this task?

  • How to make sure you see the truth with Management Studio

    - by fatherjack
    LiveJournal Tags: TSQL,How To,SSMS,Tips and Tricks Did you know that SQL Server Management Studio can mislead you with how your code is performing? I found a query that was using a scalar function to return a date and wanted to take the opportunity to remove it in favour of a table valued function that would be more efficient. The original function was simply returning the start date of the current financial year. The code we were using was: ALTER  FUNCTION...(read more)

  • How does Python compile some its code in C?

    - by Howcan
    I read that some constructs of Python are more efficient because they are compiled in C. https://wiki.python.org/moin/PythonSpeed/PerformanceTips Some of the examples used were map() and filter(). I was wondering how Python is able to do this? It's generally interpreted, so how does some of the code get compiled while another is interpreted - and in a different language? Why not just compile the whole thing?

  • Analysing Indexes - count *

    - by GrumpyOldDBA
    In my presentations on indexing I have always said that you should explore the advantages of covering your clustered index with a secondary index. In circumstances where you might want to just return values form the PK ( assuming it's your clustered index ) a secondary index will be more efficient especially when the row size is wide. Any operation on a clustered index will always return the entire row, so select ID from dbo.mytable where ID is the clustered PK integer will return not just the...(read more)

  • Blending transition in cocos2d

    - by fiddler
    In my cocos2d-iphone game, I have 2 backgrounds (CCnodes), each containing a quite complex hierarchy of sprites. I would like to make a smooth transition between them: initially, only the first background is visible at the end, only the second one is visible Is there a good way to set the opacity of a full hierarchy of sprites ? I tried to recursively set the opacity of all the contained sprites. It kinda works except that: i guess it's not very efficient i would like the opacity of overlapping sprites to be 'merged' (as if the background was one single big sprite)

  • Tournament bracket method to put distance between teammates

    - by Fred Thomsen
    I am using a proper binary tree to simulate a tournament bracket. It's preferred any competitors in the bracket that are teammates don't meet each other until the later rounds. What is an efficient method in which I can ensure that teammates in the bracket have as much distance as possible from each other? Are there any other data structures besides a tree that would be better for this purpose? EDIT: There can be more than 2 teams represented in a bracket.

  • Synchronizing audio with scrolling text

    - by mr yoshida
    I am trying to have a website that vertically scrolls about 5 paragraphs of text with a matching audio file that reads along with it. It doesn't need to be synchronized word for word such as highlighting each spoken word but an accurate start and stop time. I've searched for quite a bit on the most efficient way of doing this but can't seem to find any answers. I tried Flash but really don't want to use it. Thanks in advance.
