  • Whats the maximum key length in NSDictionary?

    - by x3ro
    Hey there, I'm currently working on an app which displays a bunch of files in a table, and you can add and remove them and whatsoever. To prevent duplicates in the table, I'd like to create a NSDictionary using the files full path as keys for another NSDictionary which contains all the file information, but I am a little concerned about the maximum key length of NSDictionary, and also whether this solution would be performance killer or not... Looking forward to your answers. Best regards, x3ro

  • Specify debug/release build in qt

    - by Royi Freifeld
    I would like Qt Creator to build the project according to the type I specify in the little computer button. Using: CONFIG(debug, debug|release) { DESTDIR = Debug OBJECTS_DIR = Debug/.obj MOC_DIR = Debug/.moc RCC_DIR = Debug/.rcc UI_DIR = Debug/.ui } CONFIG(release, debug|release) { DESTDIR = Release OBJECTS_DIR = Release/.obj MOC_DIR = Release/.moc RCC_DIR = Release/.rcc UI_DIR = Release/.ui } Or, using the answer from here, makes qmake chose the last time a variable was defined. How do I set it? Thnx P.S I don't know if it has something to do with my problem, but I'm using Ubuntu and not Windows

  • Firebird database schema/data difference tool

    - by dthrasher
    RedGate makes a tool for Microsoft SQL Server that allows you to snapshot the difference between two databases. It generates the scripts needed to update the database schema while preserving the data. I need to find a tool like this for the Firebird database. We use Firebird in an embedded fashion, and would like to push out schema updates to remote machines with as little hassle as possible.

  • Serve external template in Django

    - by AlexeyMK
    Hey, I want to do something like return render_to_response("http://docs.google.com/View?id=bla", args) and serve an external page with django arguments. Django doesn't like this (it looks for templates in very particular places). What's the easiest way make this work? Right now I'm thinking to use urllib to save the page to somewhere locally on my server and then serve with the templates pointing to there. Note: I'm not looking for anything particularly scalable here, I realize my proposal above is a little dirty.

  • Do you think it's a good idea to create a login box as a user control?

    - by Sergio Tapia
    Hi there guys! I'm starting out learning some ASP.Net programming and I'm going to be making a little community website for my friends and myself. I'm trying to pick up some good habits along the way. I was thinking of having a usercontrol and have that 'loginBox' shows the appropriate textboxes and login button, but also show his username when he is logged in. Do you think I should handle this as a user control or am I missing something as an ASP.Net newbie?

    - by malik
    Hi, A little background on the question: I am developing a RedDwarf(http://reddwarfserver.org/) client on iphone, for the client/server communication I use idarkstar.

  • PHP mp3 upload with spaces in filename

    - by Maenny
    Hi folks, I am building a site, where users can upload their mp3s and I ran into a little problem that I can't solve: The upload works fine, but only when the user selects an mp3-file which has no spaces in their mp3-filename. A file like 'My nice mp3 file.mp3' will result in a NULL of $_FILES['file']. Has this to do with Server-configurations? Anyone has an idea how to solve that? Other than telling the user just to upload mp3files without spaces in their names, that is :-) Thanx, Maenny

  • Writing user stories for internal technical tasks

    - by John Nolan
    I am attempting to manage my projects a little better so I am looking at attempting to apply some of (eventually all) the features of scrum. Looking at user stories specifically the high level format seems to be: As a User I can Feature Description or Artifact is Doing Something How would I write "Upgrade the Database"? Is it simply Upgrade the Database? I think I am being thrown off as there is no specific actor/customer and that the customer is the IT department.

  • What is(are) currently the best language(s) for modern web site design? Recommendations?

    - by Jereme Hall
    I'm a little out of date, before HTML4 and javascript got AJAXy. Does anyone have opinions about the best tools for web site design? I'd rather avoid ASP and .NET, since I've got a limited budget. This seems like a good time to start fresh. Please keep the replies on the coding recommendations, as I already know how to register a domain name, redirect it, set up Apache. (I could use some opinions on the various Apache flavors)

  • feeling insufficient while looking for a programming job ...

    - by user325661
    Hello everybody It's really dream to be programmer for me.So i always wanted to be .I had so small knowledges from commodore basic which i couldn't figure out anything in it .Then i tried to learn Visual basic 6 by myself and result wasn't good as i expected because i even didn't understand classes.Then i left to learning programming and to dream to be programmer. But challenge hadn't finished yet . After all of these i started to learn c# and i did chess engine which i hadn't believe that i can create one.I sometimes feel that i understand many thing about programming like knowing classes ,inheritance,abstract class and methods why exist , interfaces ,extension methods ,static classes ,threads. but i am not expert all in it . i just know that as i need . i don't know still i will learn many thing about these.i have also learned html, css2 , php and database concepts a little sql ,tables relations between primary keys etc but i haven't used them in praticaly . i just did some samples so i feel i am lack of knowledges. As a result still i can't evaluate my skills and can't decide what is my level.I just feel myself one step ahead of junior sometimes :) . Still can't decide that it is time to job seeking. While searching job on web i have never seen a junior advertisement. All looking for a good experiencing one.Nobody care about juniors. When found job advertisement which i feel sufficient myself a little then i start to feel that i think i can't do what they want from me and loosing job after have it in short time would leave many crap feelings into my low self-confidence. Please advise me something ... Also i want to ask some of concentrate questions. 1) If i enter a job which i can't provide their expectations should be in employers responsibility to test me while apply the job ? 2) If i answer "yes , i can " questions which is abstract(for example: can u do something like this) would be my responsibility ? Because such abstract questions is not clear and can't know before start it what i really can or not . 3) i have no professional experiences in this job so i even don't know how teams working on projects but a friend of me said that programmers only write method bodies while seniors create all project.So it looks what i can do really easy but i feel that small companies doesn't work like this so it is better work in a big company for starting who has seniors? 4)last applied job was looking for c# . net developer but then i learn that they need .net web developer.Does it take long time to learn specific sides of web programming while knowing c# desktop programming ? Thanks for all answers since now.

  • determining name of object loaded in R

    - by andrewj
    Imagine you have an object foo that you saved as saved.file.rda as follows: foo <- 'a' save(foo, file='saved.file.rda') Suppose you load saved.file.rda into an environment with multiple objects but forgot the name of the object that is in saved.file.rda. Is there a way in R to determine that name? You can do it the following way, which seems a little clunky: bar <- load('saved.file.rda') eval(parse(text=bar)) # this will pull up the object that was in saved.file.rda However, is there a better way of doing this?

  • Quick question about open_basedir

    - by Gio
    Hello, On my server, I have following setting: open_basedir /home/ :/usr/lib/php :/usr/local/lib/php :/tmp/ :/usr/local/ :/usr/bin Now, I am little bit confused about ending / in the / home / setting, does that mean that all subfolders inside home have same rights? or does it mean that only home files can be accessed? So, basically what is the main difference between: /home/ and /home With example if possible Thank you in advance.

  • Good comments on changesets in sourcecontrol

    - by Roma
    We need to develop guidelines for writing comments when we register code in version control system (such as TFS). E.g., when we submit a bugfix, we create a comment "Fixed bug #..." We tried to brainstorm on this topic, but most of the ideas bring too little added value. I would appreciate any suggestions for this.
