  • Cocoa: what is the var name of an instance created by a NIB file?

    - by Nibbles
    When a Cocoa NIB file instantiates an instance of a custom controller object, what is the name of the variable that that custom controller instance is assigned to? In case that isn't clear, if you manually created an instance of that class you would do: MyControllerClass *myVar = [[MyControllerClass alloc] init]; What equivalent of "myVar" has the NIB used when doing this behind the scenes?

  • xargs command works on ubuntu, but not mac

    - by Corey Hart
    I have the following line of code that I use to update my personal date variable in my projects to todays current date. This line works in Ubuntu's terminal, but the Mac terminal seems to be far behind. Unfortunately, I copied this snippet from some site, so I'm not sure how it exactly works. Suggestions? grep -ilr --exclude=revar.sh --exclude=README.md "[DATE]" * | grep -v .git | xargs -i@ sed -i "s/\[DATE\]/${today}/g" @

  • Dynamic jQuery Validate error messages with AddMethod based on the element

    - by mcpDESIGNS
    Let's say I have a custom AddMethod to jQuery Validate like: $.validator.addMethod('min-length', function (val, element) { // do stuff // the error message here needs to be dynamic }, 'The field cannot be less than than ' + element.attr('data-min') + // it is within the closure, but it can't grab it ' length.'); I can't figure out a way to get the element variable in question, and get any values from it. What am I missing here?

  • how to selectively filter items in a collection

    - by Samuel
    I use the following snippet to filter the list of selected users, where isSelected is a boolean variable. Is there a simpler way (helper function) to populate the selectedUsers collection instead of writing the following lines of code. List<User> selectedUsers = new ArrayList<User>(0); for (User user : this.getUsers()) { if (user.isSelected()) { selectedUsers.add(user.getId()); } }

  • File size in Python server

    - by Anna
    We have server on Python and client + web service on Ruby. That works only if file from URL is less than 800 k. It seems like "socket.puts data" in a client works, but "output = socket.gets" - not. I think problem is in a Python part. For big files tests run "Connection reset by peer". Is it buffer size variable by default somewhere in a Python?

  • How many indexes will actually get used?

    - by Ender
    I'm writing a page that does very simple search queries, resulting in something like: SELECT * FROM my_table WHERE A in (a1, a2, a3) AND B in (b1, b2) AND C in (c1, c2, c3, c4) AND And so on for a variable number of columns, usually ~5. If I create a separate index for each column (one for A, one for B, one for C, not (A,B,C)), will all of them be used in the above query?

  • In google app engine, how to iterate through form fields (python, wsgiref.handlers)

    - by MarcoB
    Using python and wsgiref.handlers, I can get a single variable from a form with self.handler.request.get(var_name), but how do I iterate through all form variables, be they from GET and POST? Is it something like this? for field in self.handler.request.fields: value = self.handler.request.get(field) Again, it should include both fields included in the POST and fields from the query string, as in a GET request. Thanks in advance folks...

  • Develop multiple very similar projects at once

    - by Raveren
    I am developing a semi-complicated site that is available in several countries at once. Much effort has been put in to make the code bases as similar as possible to one another and ultimately only the config file and some representational data will differ between them. Each project has its own SVN repository which maps directly to a live test site. That part is handled by the IDE we use to work. Now I am in need to create a some sort of system to keep all these projects in sync. The best theoretical solution so far is to create a local hook script that would fire on committing and Merge the committed files from the project that is being committed to all other projects Optionally upload them to the live site, replacing previous files The first problem is that I don't know how I would do the merging - I guess it would be like applying a SVN patch or something. The second is if I do not want to upload the changes to the live server, how would I go about synching the live and local code bases (replace older files?). I am posting this question, not going through the potentially huge trouble of solving the aforementioned problems myself is that I believe this is a pretty common situation and someone would already have a solution and others may benefit from the answers in the future. Lastly, I'm on windows7, develop PHP and use tortoiseSVN.

  • How to assign a value of a property to a var ONLY if the object isn't null

    - by Blankman
    In my code, is there a shorthand that I can use to assign a variable the value of a object's property ONLY if the object isn't null? string username = SomeUserObject.Username; // fails if null I know I can do a check like if(SomeUserObject != null) but I think I saw a shorthand for this kind of test. I tried: string username = SomeUserObject ?? "" : SomeUserObject.Username; But that doesn't work.
