  • Do you know Best Practise and Design Patterns for Adobe Air/Flex Applications?

    - by Julian
    I'm going to write an application with the Air/Flex-Framework. I'm looking for Best Practise and general Design Patterns for designing software especially in Air/Flex. I have experience with this framework but never had the pleasure to write a piece of software from scratch. For instance: I stumbled across lots of software written in Air/Flex with nearly infinity global vars :-) Most of the software I saw was not object-oriented How can I pack the asynchronous method calls nicely? I'm familiar with general design patterns by gamma. I'm looking more for advise in designing good quality software with Adobe Air/Flex.

  • How to repeatedly show a Dialog with PyGTK / Gtkbuilder?

    - by Julian
    I have created a PyGTK application that shows a Dialog when the user presses a button. The dialog is loaded in my __init__ method with: builder = gtk.Builder() builder.add_from_file("filename") builder.connect_signals(self) self.myDialog = builder.get_object("dialog_name") In the event handler, the dialog is shown with the command self.myDialog.run(), but this only works once, because after run() the dialog is automatically destroyed. If I click the button a second time, the application crashes. I read that there is a way to use show() instead of run() where the dialog is not destroyed, but I feel like this is not the right way for me because I would like the dialog to behave modally and to return control to the code only after the user has closed it. Is there a simple way to repeatedly show a dialog using the run() method using gtkbuilder? I tried reloading the whole dialog using the gtkbuilder, but that did not really seem to work, the dialog was missing all child elements (and I would prefer to have to use the builder only once, at the beginning of the program). [SOLUTION] As pointed out by the answer below, using hide() does the trick. But one has to take care that the dialog is in fact destroyed if one does not catch its "delete-event". A simple example that works is: import pygtk import gtk class DialogTest: def rundialog(self, widget, data=None): self.dia.show_all() result = self.dia.run() def destroy(self, widget, data=None): gtk.main_quit() def closedialog(self, widget, data=None): self.dia.hide() return True def __init__(self): self.window = gtk.Window(gtk.WINDOW_TOPLEVEL) self.window.connect("destroy", self.destroy) self.dia = gtk.Dialog('TEST DIALOG', self.window, gtk.DIALOG_MODAL | gtk.DIALOG_DESTROY_WITH_PARENT) self.dia.vbox.pack_start(gtk.Label('This is just a Test')) self.dia.connect("delete-event", self.closedialog) self.button = gtk.Button("Run Dialog") self.button.connect("clicked", self.rundialog, None) self.window.add(self.button) self.button.show() self.window.show() if __name__ == "__main__": testApp = DialogTest() gtk.main()

  • no such file to load -- rails (MissingSourceFile)... say what?!!

    - by Julian
    Hello, I'm having an obnoxious and weird problem while trying to include the ThinkingTank gem into my rails project. When I include gem 'thinkingtank' in my project's Gemfile I get the following error: ~/.rvm/gems/ree-1.8.7-2010.01/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require': no such file to load -- rails (MissingSourceFile) from ~/.rvm/gems/ree-1.8.7-2010.01/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from ~/.rvm/gems/ree-1.8.7-2010.01/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in `new_constants_in' from ~/.rvm/gems/ree-1.8.7-2010.01/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in `require' from ~/.rvm/gems/ree-1.8.7-2010.01/gems/thinkingtank-0.0.5/lib/thinkingtank.rb:1 from ~/.rvm/gems/ree-1.8.7-2010.01/gems/bundler-1.0.7/lib/bundler/runtime.rb:64:in `require' from ~/.rvm/gems/ree-1.8.7-2010.01/gems/bundler-1.0.7/lib/bundler/runtime.rb:64:in `require' from ~/.rvm/gems/ree-1.8.7-2010.01/gems/bundler-1.0.7/lib/bundler/runtime.rb:62:in `each' from ~/.rvm/gems/ree-1.8.7-2010.01/gems/bundler-1.0.7/lib/bundler/runtime.rb:62:in `require' from ~/.rvm/gems/ree-1.8.7-2010.01/gems/bundler-1.0.7/lib/bundler/runtime.rb:51:in `each' from ~/.rvm/gems/ree-1.8.7-2010.01/gems/bundler-1.0.7/lib/bundler/runtime.rb:51:in `require' from ~/.rvm/gems/ree-1.8.7-2010.01/gems/bundler-1.0.7/lib/bundler.rb:112:in `require' from ~/git/myproject/config/boot.rb:121:in `load_environment' from ~/.rvm/gems/ree-1.8.7-2010.01/gems/rails-2.3.5/lib/initializer.rb:137:in `process' from ~/.rvm/gems/ree-1.8.7-2010.01/gems/rails-2.3.5/lib/initializer.rb:113:in `send' from ~/.rvm/gems/ree-1.8.7-2010.01/gems/rails-2.3.5/lib/initializer.rb:113:in `run' from ~/git/myproject/config/environment.rb:9 from ~/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/1.8/irb/init.rb:254:in `require' from ~/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/1.8/irb/init.rb:254:in `load_modules' from ~/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/1.8/irb/init.rb:252:in `each' from ~/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/1.8/irb/init.rb:252:in `load_modules' from ~/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/1.8/irb/init.rb:21:in `setup' from ~/.rvm/rubies/ree-1.8.7-2010.01/lib/ruby/1.8/irb.rb:54:in `start' from ~/.rvm/rubies/ree-1.8.7-2010.01/bin/irb:17 The output from ruby -v is: ruby 1.8.7 (2009-12-24 patchlevel 248) [i686-darwin10.6.0], MBARI 0x6770, Ruby Enterprise Edition 2010.01 And the output from rails -v is: Rails 2.3.5 I've followed the basic guidelines from their documentation and from similar SA questions.

  • HD Crash SQL server -> DBCC - consistency errors in table 'sysindexes'

    - by Julian de Wit
    Hello A client of mine has had an HD crash an a SQL DB got corrupt : They did not make backups so they have a big problem. When I tried (an ultimate measure) to DBCC-repair I got the following message. Can anybody help me with this ? Server: Msg 8966, Level 16, State 1, Line 1 Could not read and latch page (1:872) with latch type SH. sysindexes failed. Server: Msg 8944, Level 16, State 1, Line 1 Table error: Object ID 2, index ID 0, page (1:872), row 11. Test (columnOffsets->IsComplex (varColumnNumber) && (ColumnId == COLID_HYDRA_TEXTPTR || ColumnId == COLID_INROW_ROOT || ColumnId == COLID_BACKPTR)) failed. Values are 2 and 5. The repair level on the DBCC statement caused this repair to be bypassed. CHECKTABLE found 0 allocation errors and 1 consistency errors in table 'sysindexes' (object ID 2). DBCC execution completed. If DBCC printed error messages, contact your system administrator.

  • Android - Showing Dialog from custom component

    - by Julian Arz
    Hi! I am writing a custom component (derived from a relative layout) which has to show a dialog, Is there a way to do this using callbacks like oncreatedialog or onpreparedialog? if not: if i have to create the dialog outside oncreatedialog, i have to "attach it to an Activity with setOwnerActivity(Activity)". How can the custom component access the activity it is used in, when it is used in the activity's xml-layout and not created from code?

  • Any way to specify a non-positional parameter in a powershell script?

    - by Julian Birch
    I've got the following at the start of a script Param( [string]$command, [string]$version = "1.1.0" ) This is fine, only I need for $version to not be a positional parameter, so that if you type .\script.ps1 run argument Then $args should contain argument and $version should be 1.1.0. Is this even possible? I know I can do it with a c# cmdlet, but it would be massively more convenient if I could deliver this as a single script.

  • How do i translate this to "simpler" JavaScript?

    - by Julian Weimer
    Since i'm working with Titanium i realzed that its current JavaScript Interpreter doesn't accept specific coding-styles. So for for-loops and if-statements i have to have braces, even though i only want to span one line. Furthermore there is more i have to change if i want to use a Javascript Library like underscore.js. This is what Titanium doesn't want to see: if (!(result = result && iterator.call(context, value, index, list))) {_.breakLoop();} if (nativeSome && obj.some === nativeSome) {return obj.some(iterator, context);} var computed = iterator ? iterator.call(context, value, index, list) : value; computed >= result.computed && (result = {value : value, computed : computed}); Can i use a simpler syntax to describe the logic behind those lines of code?

  • MySQL update with two subqueries

    - by Julian Cvetkov
    I'm trying to update one column of MySQL table with subquery that returns a date, and another subquery for the WHERE clause. Here is it: UPDATE wtk_recur_subs_temp SET wtk_recur_date = (SELECT final_bb.date FROM final_bb, wtk_recur_subs WHERE final_bb.msisdn = wtk_recur_subs.wtk_recur_msisdn) WHERE wtk_recur_subs_temp.wtk_recur_msisdn IN (select final_bb.msisdn from final_bb) The response from the MySQL engine is "Subquery returns more than 1 row".

  • How to implement a Mutex in Python when using Gtk with PyGTK

    - by Julian
    Hi, I have an application that starts several threads using gobject.timeout_add(delay, function) Now in my function I want to test and set on some variable, e.g. def function(self): if flag == True: flag = False doSomething() Now to make this threadsafe, I would have to lock the function using some mutex lock. Is this possible with Gtk? Or can I use the Python Lock objects from threading?

  • Pre loaded database on iPhone?

    - by Julian
    Hi, I have recently developed an app using core data as the storage db. The app allowed the user to read and write to the db. I am now developing a new app which the user doesnt need to write anything to the db, instead the app just needs to read the data. The data has relationships etc so cannot just use a plist or something similar. My question is should I use core data for such a requirement and if so how would i go about entering the data and then releasing the app. Would I have to code the data entry which would populate the db then remove all this code (as I dont want the database to repopulate every time the user opens the app)?? Is there a way to create a core data model using sql commands as with sqlite ie insert into..... etc? Any ideas/thoughts would be very helpful. Many thanks Jules

  • Which JavaScript Libraries do not rely on a document and navigator object?

    - by Julian Weimer
    I'm currently looking for some libraries which might help me during iPhone Development using Appcelerator Titanium. I've heard that since version 1.0 it isn't dependant on webkit anymore and it makes app-development more exiting of course, please correct me if i'm wrong. As many people out there i love Javascript Frameworks such as JQuery and Mootools much, but they were build specifically to do a great job within a browser and most of the functionality is not needed within the environment Titanium now provides (DOM-Manipulation etc). Is there any other small library of useful functions i can use for development? Thx in advance.

  • How might one detect the first run of a program?

    - by Julian H. Lam
    In my web application, users can download a .tar.gz archive containing the app files. However, because the MySQL database won't have been configured then, the user needs to run the install script located in ./install. I "catch" the user upon first run of the app by checking to see if the ./install directory exists. If so, the index.php page redirects the user to the install script. However, I was wondering if there were a more elegant way to "catch" a user upon first-run of a program. Someone on IRC suggested the web-server create a file .installed upon completion, but because the web server might not have write privileges to the web root directory, I can't rely on that. How would you go about solving this problem, or is my solution workable?

  • Any way to avoid a filesort when order by is different to where clause?

    - by Julian
    I have an incredibly simple query (table type InnoDb) and EXPLAIN says that MySQL must do an extra pass to find out how to retrieve the rows in sorted order. SELECT * FROM `comments` WHERE (commentable_id = 1976) ORDER BY created_at desc LIMIT 0, 5 exact explain output: table select_type type extra possible_keys key key length ref rows comments simple ref using where; using filesort common_lookups common_lookups 5 const 89 commentable_id is indexed. Comments has nothing trick in it, just a content field. The manual suggests that if the order by is different to the where, there is no way filesort can be avoided. http://dev.mysql.com/doc/refman/5.0/en/order-by-optimization.html I also tried order by id as well as it's equivalent but makes no difference, even if I add id as an index (which I understand is not required as id is indexed implicitly in MySQL). thanks in advance for any ideas!

  • Sharing rails fragments between formats

    - by Julian
    Hi I'm toying with mobile_fu and want to share some fragments between the different views. E.g. views/ item/ view.html.erb view.mobile.rb shared/ _common.erb In both view.html.erb and view.mobile.erb I want to share the same fragment '_common.erb' without having to specify the format (should you ever have to specify the format inside a fragment? It doesn't seem like The Rails Way?). Let's say for arguments's sake it's because it's in a helper or whatever -- the point is that I need to share fragments in a 'well-defined and Railsy way' across formats. Let's take this fairly innocuous snippet <% render :fragment => 'shared/common' %> I've tried 3 file name conventions: _common.html.erb only works for html /item/view/xx fails with 'shared/_common.erb not found') however _common.erb fails for html and works for mobile (maybe mobile_fu is doing something wacky?) -- same error as for .html.erb version above _common.rhtml does work for both I'm thinking that: that rhtml works for both is a legacy hack and I'm loathe to rename all the shared fragments .rhtml to get the behaviour I want. Any feedback gratefully welcome! Including 'you fundamentally don't understand how Rails works please RTFM here: http://....' :)

  • Looping through NSArray while subtracting values from each object? [on hold]

    - by Julian
    I have NSNumber objects stored in an NSMutableArray. I am attempting to perform a calculation on each object in the array. What I want to do is: 1) Take a random higher number variable and keep subtracting a smaller number variable in increments until the value of the variable is equal to the value in the array. For example: NSMutableArray object is equal to 2.50. I have an outside variable of 25 that is not in the array. I want to subtract 0.25 multiple times from the variable until I reach less than or equal to 2.50. I also need a parameter so if the number does not divide evenly and goes below the array value, it resorts to the original array value of 2.50. Lastly, for each iteration, I want to print the values as they are counting down as a string. I was going to provide code, but I don't want to make this more confusing than it has to be. So my output would be: VALUE IS: 24.75 VALUE IS: 24.50 VALUE IS: 24.25 … VALUE IS: 2.50 END

  • Looking for a fast hash-function.

    - by Julian
    Hello, I'm looking for a special hash-function. Let's say I have a large list of strings, if I order them by their hash-values they should be ordered quasi randomly. The most important point is: it must be super fast. I've tried md5 and sha1 and they're using to much cpu power. Clashes are not a problem. I'm using javascript, so it shouldn't be too complicated to implement.

  • Domino 9 / Dojo 1.8 - Date Time Picker without default value

    - by Julian Buss
    I want a Date Time Picker control WITHOUT a default value. Doesn't seem to be possible anymore :-( To reproduce, create a blank XPage and place a Date Time Picker control. Open the XPage in the browser and you will see that it defaults to today. I didn't found any way to set the default to an empty value. I tried setting all properties/data/default to 0, null, empty string and so on - no luck. I tried the data-dojo-probs attribute with value:'', this sets the default to 1970-1-1, but not to blank. Any ideas?

  • build-helper-maven-plugin add-source does not working when trying to add linked resources

    - by Julian
    I am new to maven and hit a problem that looks easy in the first place but I already kept me busy for a whole day about and no way to get it working. First as part of running eclipse:eclipse plugin I create a linked folder like below: <linkedResources> <linkedResource> <name>properties</name> <type>2</type> <location>${PARENT-2-PROJECT_LOC}/some_other_project/properties</location> </linkedResource> <linkedResource> <name>properties/messages.properties</name> <type>1</type> <location>${PARENT-2-PROJECT_LOC}/some_other_project/properties/messages.properties</location> </linkedResource> And then I am adding that folder as a source folder like below: <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>build-helper-maven-plugin</artifactId> <version>1.7</version> <executions> <execution> <id>add-source</id> <phase>generate-sources</phase> <goals> <goal>add-source</goal> </goals> <configuration> <sources> <source>properties</source> <source>some_real_folder</source> </sources> </configuration> </execution> </executions> </plugin> However when I am looking at the generated .classpath in eclipse the “some_real_folder” is there but the “properties” is not. It looks like by default the build-helper-maven-plugin will check if the folder is there and if it is not it won’t add it. I am using maven 3.0.4 outside eclipse to run the build and I can see in the maven logs something like this: [INFO] Source directory: <some path>\properties added. This is my project structure: project1 \-- properties (this is the real folder) project2 \-- some_real_folder \-- properties (this is the link resource pointing to the project1/properties folder) All I need is to have both "some_real_folder" and the linked resource "properties" added to the .classpath of the project2

  • Dividing n-bit binary integers

    - by Julian
    Was wondering if anyone could help me with creating a pseudocode for how to go about dividing n-bit binary integers. Here is what I'm thinking could possibly work right now, could someone correct this if I'm wrong: divide (x,y) if x=0: return (0,0) //(quotient, remainder) (q,r) = divide(floor(x/2), y) q=2q, r=2r if x is odd: r = r+1 if r >= y: r = r-y, q = q+1 return (q,r) Would you guys say that this general pseudocode algorithm would accomplish the intended task of dividing n-bit numbers or am I missing something in my psuedocode before I start coding up something that's wrong?

  • Why don't hardware failures show up at the programming language level?

    - by Julian Cienfuegos
    I am wondering if anyone can give my a good answer, or at least point me in the direction of a good reference to the following question: How come I have never heard of a computer breaking in a very fundamental way? How come when I declare x to be a double it stays as a double? How come there is never a short circuit that robs it of some bytes and makes it an integer? Why do we have faith that when we initialize x to 10, there will never be a power surge that will cause it to become 11, or something similar? I think I need a better understanding of memory. Thanks, and please don't bash me over the head for such a simple/abstract question.
