  • What is the best way to flag some elements in MATLAB? using NaN or Inf? or something else?

    - by Kamran Bigdely Shamloo
    As you may know, in many occasions, there is a need to flag some elements of a matrix. For example when we have weighted adjacency matrix, and our graph is not fully connected, we have to flag some elements to show that there is no edge between those nodes. The question is how to do that? Is it better to put NaN or Inf on that elements in the matrix? or something elese(such as -1)?

  • NANT: ReplaceToken, loop over all properties defined in build

    - by SharePoint Newbie
    Hi, Is it possible to loop over all the properties and replace all token which correspond to them? For example, if I have three properties defined, a,b,c, I want to replace all three tokens @a@, @b@, @c@ . I however do not want to set up the filterchain manually as properties may be added/removed later on. I can accomplish this using a custom nant task, but is ther a way to do this through a build file alone. Thanks,

  • Rails wiki highlight/strikethrough version differences between article versions

    - by mark
    Hi I'm wondering how to implement highlighting of changes to user edited articles on a wiki style rails project. Since articles may be fairly lengthy I'd ideally like strikethrough and highlighting, similar to github and wikipedia for example. Despite searching around the net I've not really come up with much, apart from instiki which is a complete wiki application. Thanks in advance for any advice.

  • SharePoint Transferring pages to Production

    - by bmw0128
    I am building an internet site, using my local machine as the development box (I have MOSS 2007 installed). I have a custom master page, packaged in a WSP, so I may use STSADM on the production server to install it. I have made some pages via SPD (on my local machine) and put them in the "Pages" gallery. What is the recommended way to get these pages to production. Also, is the process the same when I make edits to current pages?

  • Why does sorted list have to have a key value pair?

    - by clawson
    If I just want a sorted list of just dates, integers, or doubles is it really necessary to have to define a SortedList(of Integer, Integer)? Seems intriguing to me, but may just be trival. I'd prefer just to use a SortedList(of Integer). (This question is in relation to the .Net generic collections)

    - by Adam Paynter
    In light of the "Hidden features of..." series of questions, what little-known features of PL/SQL have become useful to you? Edit: Features specific to PL/SQL are preferred over features of Oracle's SQL syntax. However, because PL/SQL can use most of Oracle's SQL constructs, they may be included if they make programming in PL/SQL easier.

  • Calling overridden parent method from parent method

    - by Yisroel
    Heres the situation. Component B extends component A and overrides the init method to accept a different parameter. A also has a create method that calls init. If i have an instance of B and i call create, its calling the wrong init - it calls init in B, where i need it to call init in A. I dont want to call super.init() as there may not always be a super. Is there any way to specify to call the init in the parent component?

  • MySQL VARCHAR strange column behavior

    - by Mat
    I have the following SQL statement which returns a single record as expected: select * from geodatasource_cities C, geodatasource_countries D where C.CC_FIPS = D.CC_FIPS and D.CC_ISO='AU' and UCASE(TRIM(C.FULL_NAME_ND)) LIKE '%JAN JUE%'; However, If I use the following SQL statement, no records are returned. I have only changed the LIKE clause to an equal to clause: select * from geodatasource_cities C, geodatasource_countries D where C.CC_FIPS = D.CC_FIPS and D.CC_ISO='AU' and UCASE(TRIM(C.FULL_NAME_ND)) = 'JAN JUE'; Can anybody please help me understand why this may be happening?
