  • How to get LSB bit in MIPS?

    - by israkir
    Is there a short way to check/get for least significant bit in a 32-bit integer, in MIPS? It is obviously set for the odd numbers and an algorithm which checks for the whole number is odd or even can decide for this. But I just wonder is there a better way to do this...

  • OpenCV performance in different languages

    - by h0b0
    I'm doing some prototyping with OpenCV for a hobby project involving processing of real time camera data. I wonder if it is worth the effort to reimplement this in C or C++ when I have it all figured out or if no significant performance boost can be expected. The program basically chains OpenCV functions, so the main part of the work should be done in native code anyway.

  • iPhone apps for company-internal use - possible?

    - by Michael Stum
    I hope this is still programming related, as SuperUser doesn't seem the appropriate place. Basically I wonder if it is possible to have Applications that are internal to a company on the iPhone? That is something like a companion Application to an Intranet (when Safari and Mail just don't cut it) which wouldn't make sense on the AppStore (and likely wouldn't get approved anyway). Is something like that possible (without Jailbreaking or doing anything else that Apple doesn't normally want)?

  • Placeholder for UITextView

    - by Gill Bates
    Anyone ever implements something in UITextView that stopping it from receiving future inputs when the text length is smaller than certain threshold? I plan to implement a textview like we have in the mail composer interface. We have a placeholder "Subject" there, and the cursor starts after. Placeholder in UITextView Inspired from this question, I wonder if there are some methods which could be used to stop changing the text in the UITextView once the cursor is moving back to the placeholder string. Any ideas?

  • How to create a simple browser-based IRC client?

    - by WoppyCold
    I want to implement a chat service on my site, and wonder how to create a simple browser-based IRC client? I have a linux box and can install whatever I want on it. Google finds tutors on how to setup an IRC server but no instructions on how to create an IRC client. (As client languages, I can use JavaScript or Flash.)

  • SAS on OS X any way to run without working within virtual machine?

    - by user309284
    I would like to edit and submit SAS code from emacs (aquamacs) on OS X to SAS running on Vista (through Parallels). Any idea how to do this? I like to do everything through one place and it is really annoying to work within the windows emulator. I have run SAS from a linux server through aquamacs but wonder if something similar can be done locally. Any ideas?

  • Load a list of localized strings at once in IOS

    - by Victor Ronin
    I want to show a table with the list of strings which are localized. The straightforward method would be: a) Point data source to my ViewController b) Define an array c) Allocate the array in my ViewController and init (arrayWithObjects) it with the strings from localized resources (NSLocalizedString) d) Use this array in UITableViewDataSource delegated methods Mainly my concern is item b). The construction looks quite heavy and I wonder whether I can somehow specify and load whole list of localized string at once.

  • How can I use "FOR UPDATE" with a JOIN on Oracle?

    - by tangens
    The answer to another SO question was to use this SQL query: SELECT o.Id, o.attrib1, o.attrib2 FROM table1 o JOIN ( SELECT DISTINCT Id FROM table1, table2, table3 WHERE ... ) T1 ON o.id = T1.Id Now I wonder how I can use this statement together with the keyword FOR UPDATE. If I simply append it to the query, Oracle will tell me: ORA-02014: cannot select FOR UPDATE from view Do I have to modify the query or is there a trick to do this with Oracle? With MySql the statement works fine.

  • How to enable nullptr from C++0x in the Visual C++ 2010?

    - by Sorin Sbarnea
    I wonder how can I enable the nullptr in the just released Visual Studio 2010. (C++ project, not managed). This is one of the new features but it is not available by default and looking inside the documentation at http://msdn.microsoft.com/en-us/library/4ex65770(VS.100).aspx it seams that it is enabled by /clr but this is managed! Is this a feature added only for .NET?

But on zooming i continue see the triangle's under the skin, it's not smooth. I use OpenGL built-in minMapping. So I wonder (lookig at other products) do i need to implement my own mipMapping algorithm or I'm doing something wrong ? This is what I want , more ore less, like a quality:

  • Why do updates inside of a SQL transaction still need disk IO?

    - by usr
    In SQL Profiler you can see that very simple updates to a table by primary key take about 10-30ms each. On about every 10th update the write column shows 1, on all other updates it shows 0. This must mean that about every 10th update statement still requires disk IO. I wonder why that is. Would it not be more efficient queue up all IO until the transaction commits?

  • Why do encodeXxx methods in UIComponent accept FacesContext parameter?

    - by Roman
    I haven't ever before created custom components in JSF so I've noticed only now that methods like encodeBegin(), encodeEnd() etc accept FacesContext parameter. FacesContext instance can usually be received with FacesContext.getCurrentInstance(). So, I wonder whether these methods have FacesContext parameter just for convenience or some different objects can be passed there (maybe from external resources..). If the latter is possible then could you give an example pls.

  • How do "modern JVMs" differ from older JVMs?

    - by Lord Torgamus
    Here's a phrase that I heard a lot throughout high school and university computer science classes: "That's not an issue for modern JVMs." Usually this would come up in discussions about overall performance or optimization strategies. It was always treated as a kind of magical final answer, though, as if it makes issues no longer worth thinking about. And that just leads me to wonder: what are the differences between the prototypical "modern JVM" and older JVMs, really?

  • Sort months ( with strings ) algorithm

    - by Oscar Reyes
    I have this months array: ["January", "March", "December" , "October" ] And I want to have it sorted like this: ["January", "March", "October", "December" ] I'm currently thinking in a "if/else" horrible cascade but I wonder if there is some other way to do this. The bad part is that I need to do this only with "string" ( that is, without using Date object or anything like that ) What would be a good approach?
