  • Masked functions in R

    - by user227290
    This is a newbie question in R. If you have two libraries in R with same function name (and one masking the other) then how do you use the masked function. A concrete example: Both UsingR and QRMlib have the function QQPlot(), and UsingR's QQplot is masking that of QRMlib. How can I use the QQplot function of QRMlib. Thank you

  • Connecting CoreData to my App on an iPhone Device

    - by Lauren Quantrell
    I apologize ahead of time for what I'm sure is a complete newbie lapse. Running my iPhone app on iPhone simulator - no problem. But I loaded the app on an iPhone device for the first time and it appears as if the SQLite database I'm using (NSManagedObjectContext) isn't connected or didn't upload. The app installs but with no data. How do I get it all to upload and work on the device? I appreciate any help. lq

  • Where to read about programming?

    - by minx
    I'm a programmer for some time now yet I haven't found the right websites which offer me the information I'm interested in. I've looked at TechCrunch, Slashdot, etc. but there wasn't so much actually about programming. When something urgently important happens in the programming world, where could I read it first? What are some good sites/communities around programming?

  • Which computer assisted translation format should I use for a ColdFusion site?

    - by user284950
    I am creating a multilingual site that will need to support at minimum five different languages, including Korean and Chinese. The site language is ColdFusion, so Java is the native language. I want to make the site as easy as possible for the next programmer to update, and for third-party translators to use tools that will work easier for them than digging through a SQL database. So far I have come across Resource Bundles, GNU's GetText, and TMX. Which do you recommend and why?

    Hi, I'm a newbie in applescript.

So, how is the best way to iterate over a list? TIA, Bob

  • What was the single byte change to port WordStar from CP/M to DOS?

    - by amarillion
    I was re-reading Joel's Strategy Letter II: Chicken and Egg problems and came across this fun quote: In fact, WordStar was ported to DOS by changing one single byte in the code. (Real Programmers can tell you what that byte was, I've long since forgotten). I couldn't find any other references to this with a quick Google search. Is this true or just a figure of speech? In the interest of my quest to become a "Real Programmer", what was the single byte change?

  • What can I do to avoid losing original resolution when uploading or exporting photos from Picasa?

    - by Janet Levin
    I'm not a programmer, and/but after multiple email discussions and google searches confirmed the problem I'm describing, and after making changes in picasa preferences with no change in resolution loss (from say, 800kb original image to 235kb after export or upload), I'm at a dead end and thinking the answer may lie among you folks, even though I barely understand the language here.

  • Path managment in Linux programs

    - by petersohn
    I have a newbie Linux programming question. Suppose I have a project that uses Autotools for compiling and deployment, and I have data files that are to be installed in a location like /var/something or /usr/share/something etc., but in Autoconf, I can change these installation paths. How should the program find these files? How does it know where they are actually installed (if anywhere, since the program should work even if not installed, but run from where it was built)?

  • How does porting between Linux and Windows work?

    - by Matt
    If a particular piece of software is made to be run on one platform and the programmer/company/whatever wants to port it to the other, what exactly is done? I mean, do they just rewrite linux or windows-specific references to the equivalent in the other? Or is an entire rewrite necessary? Just trying to understand what makes it so cost-prohibitive that so many major vendors don't port their software to Linux (specifically thinking about Adobe) Thanks
