• Trouble making OAuth signed requests

  - by behrk2

  Hello, I am able to successfully make non-authenticated and protected calls to the Netflix API. I am having a little trouble making signed requests to the catalog, however. Using the OAuth Test page, it is clear to me that my Base String is correct. My request URL is also correct, except for the oauth_signature. The oauth_signature is the only thing that differs. If I understand correctly, the only difference between a protected call and a signed call is that there are no tokens involved, and that I am appending on call parameters (such as term). So, I am using the exact same code that I use for my protected calls that I am for my signed calls, except my signature key ONLY contains my shared secret (with an ampersand sign on the end of it). It does not use the access token. Am I missing something here? Where else can I be going wrong? Thanks!

• Why does my NSWindow only receive mouseOver events the first time?

  - by DanieL

  I have an application where a borderless window is shown and hidden, using orderOut and orderFront. When it is visible, I want the it to become the key window when the mouse moves over it. So far I've done this: In awakeFromNib I have set its first responder to itself. In the window's constructor I set accepts mouse events to YES. In the mouseMoved method, I use makeKeyAndOrderToFront. My problem is, that this only works the first time I move the mouse over the window. After that, it doesn't receive any mouseOver events. I've tried checking the firstResponder but as far as I can tell it never changes from the window. Any ideas what I can do to get this working?

• Base-camp Style Subdomains and IDs of Models

  - by Newy

  I have an app that has Basecamp-style subdomains, that is, I have Projects, Users, Apples and Oranges. The Users, Apples and Oranges are all keyed to a Project and only exist in the http://project.myapp.com. I added a project_id to Users, Apples and Oranges and everything works, except of course that the ids of those three objects increment globally, and throughout my app I lookup objects by that id. This doesn't seem like best practice. Should I instead do lookups by a secondary key? How does that affect efficiency? If there's a good blog post that covers this, would be wesome.

• Google Maps - user to pinpoint a location

  - by JohnB

  Hi, Is it possible to allow users of my website to mark places on a map I display using Google Maps API? I need to then save that location coordinates to a db. I've been looking through the google maps API, I found that I can use the web service to do searches like this: http://maps.google.com/maps/geo?q=Maine,+United+States&output=json&oe=utf8\&sensor=false&key=my_key But I am not sure it's working on a house number level (which I need it to) and I'm not sure how to display a 'did you mean?' to the user when he misspells the address.. Anyone have an idea? Thanks,

• Simple number-to-number (or number-to-hex) encryption algorithm that minimizes # of characters

  - by Clay Nichols

  I need to encrypt a number and I and this encrypted value will be given to a customer ask a key so I want to minimize the number of digits and make them all printable. So I'd like the result to be either all number or all Hex characters. The current encryption method I'm using (for non numbers) converts the characters to hex (2 hex digits each). That doubles the number of characters. I also considered just treating the input as hex (so each pair of numbers is treated as a Hex pair, but then you have ambiguity between an input of 0123 and 123 (when decrypting that leading '0' is lost. Any suggestions?

• Mac OS X pygame input goes to Terminal instead of Python

  - by Parappa

  I'm having trouble running a pygame based app on Mac OS X via Terminal. Input events such as keystrokes go to the Terminal instead of my Python app, and are detected by pygame. For example, I have the following test script: import pygame pygame.init() screen = pygame.display.set_mode((640, 480)) done = False while not done: pygame.event.pump() keys = pygame.key.get_pressed() if keys[pygame.K_ESCAPE]: done = True if keys[pygame.K_SPACE]: print "got here" Neither K_ESCAPE nor K_SPACE will be handled by this script when I run it from a Mac OS X Terminal, but Terminal will echo back the spaces. I'm running the MacPorts port of pygame (py-game), which depends on Python 2.4, and I've also used python_select to make python24 the active version.

• OOP Design Question - Where/When do you Validate properties?

  - by JW

  I have read a few books on OOP DDD/PoEAA/Gang of Four and none of them seem to cover the topic of validation - it seems to be always assumed that data is valid. I gather from the answers to this post (http://stackoverflow.com/questions/1651964/oop-design-question-validating-properties) that a client should only attempt to set a valid property value on a domain object. This person has asked a similar question that remains unanswered: http://bytes.com/topic/php/answers/789086-php-oop-setters-getters-data-validation#post3136182 So how do you ensure it is valid? Do you have a 'validator method' alongside every getter and setter? isValidName() setName() getName() I seem to be missing some key basic knowledge about OOP data validation - can you point me to a book that covers this topic in detail? - ie. covering different types of validation / invariants/ handling feedback / to use Exceptions or not etc

• Silverlight MEF Embedded Resources

  - by Fastidious

  I have two different Silverlight UserControls imported with MEF from two different xaps. The UserControls are simply an Image on a Canvas. Both UserControls have the image marked as 'Resource'. The images are different but their names are the same (key point). I'm not quite sure what's going on behind the scenes of the MEF import but both images seem to end up in the same AppDomain. After the composition when I stick the UserControls on a Canvas, each is an instance of the class it should be, but they both show the same image. Obviously if the image file names are unique across all xaps I import I have no problem but I don't like that solution. Is there a better one?

• gradle runJar task?

  - by Misha Koshelev

  Dear All: I am trying to make a task to run my Jar file in gradle. I have come up with the following: task runJar(dependsOn:[jar]){ ant.java(jar:,fork:true) } However, I am unable to find the path to the jar file. Any help much appreciated. Thank you! Misha EDIT: OK this is rather odd. This task runs before compile, etc.??? EDIT: Fixed. The key is in a doLast { } notation, or, in shorthand task runJar(dependsOn:"jar")<<{ ant.java(jar:"${libsDir}${File.separator}${archivesBaseName}.jar",fork:true) } Misha

• How to make strtotime parse dates in Australian (i.e. UK) format: dd/mm/yyyy?

  - by Iain Fraser

  I can't beleive I've never come across this one before. Basically, I'm parsing the text in human-created text documents and one of the fields I need to parse is a date and time. Because I'm in Australia, dates are formatted like dd/mm/yyyy but strtotime only wants to parse it as a US formatted date. Also, exploding by / isn't going to work because, as I mentioned, these documents are hand-typed and some of them take the form of d M yy. I've tried multiple combinations of setlocale but no matter what I try, the language is always set to US English. I'm fairly sure setlocale is the key here, but I don't seem to be able to strike upon the right code. Tried these: au au-en en_AU australia aus Anything else I can try? Thanks so much :) Iain Example: $mydatetime = strtotime("9/02/10 2.00PM"); echo date('j F Y H:i', $mydatetime); Produces 2 September 2010 14:00 I want it to produce: 9 February 2010 14:00

• How to get a list of items when using cassandra

  - by Blankman

  When using a nosql type datastore like Cassandra, how would you return a result set based on a column? e.g. SELECT * FROM Articles WHERE category='blah' ORDER BY datetime DESC is this something that you would store in a sql db and then pull the data from cassandra? Or can cassandra handle this type of query? (assuming millions of rows in a db) From what I understand, cassandra is great at key based lookups, confused if it can and should be used for getting a list of data back and paging that data also (and if it is highly performant)

• i18n Spring MVC

  - by Enrique

  Hello. I want to use SessionLocaleResolver to get the locale from user session. The documentation says this: "Another option of resolving locales is by SessionLocaleResolver. It resolves locales by inspecting a predefined attribute in a user’s session. If the session attribute doesn’t exist, this locale resolver will determine the default locale from the accept-language HTTP header." But it does not say which attribute do I have to put in session. Y tried saving in session an attribute "lang" with value "en" but it did not work. Anybody knows which attribute do I have to save in session (key,value)?

• Zend framework currency validation

  - by Dan

  How can I validate (a form element in this case) to ensure that the value is a currency? Have looked at Zend_Validate_Float. Needs to check that value is between 0 and 2dp. Ideally locale-aware (as ZVF is) to allow for locale specific formatting (thousands, decimal as comma/dot) Would also want to extend to allow/disallow negative values And provide optional upper/lower limits. Is the key, as I can do 3. and 4. with a chain. Do I need regex?

• AES Encryption. From Python (pyCrypto) to .NET

  - by Why

  I am currently trying to port a legacy Python app over to .NET which contains AES encrpytion using from what I can tell pyCrpyto. I have very limited Python and Crypto experience. The code uses the snippet from the following page. http://www.djangosnippets.org/snippets/1095/ So far I believe I have managed to work out that it that it calls Crypto.Cipher with AES and the first 32 character of our secret key as the password, but no mode or IV. It also puts a prefix on the encrpyed text when it is added to database. What I can't work out is how I can decrypt the existing ecrypted database records in .NET. I have been looking at RijndaelManaged but it requires an IV and can't see any reference to one in python. Can anyone point me in the dirrection to what method could be used in .NET to get the desired result.

• python socket.recv/sendall call blocking

  - by fsm

  Hi everyone. This post is incorrectly tagged 'send' since I cannot create new tags. I have a very basic question about this simple echo server. Here are some code snippets. client while True: data = raw_input("Enter data: ") mySock.sendall(data) echoedData = mySock.recv(1024) if not echoedData: break print echoedData server while True: print "Waiting for connection" (clientSock, address) = serverSock.accept() print "Entering read loop" while True: print "Waiting for data" data = clientSock.recv(1024) if not data: break clientSock.send(data) clientSock.close() Now this works alright, except when the client sends an empty string (by hitting the return key in response to "enter data: "), in which case I see some deadlock-ish behavior. Now, what exactly happens when the user presses return on the client side? I can only imagine that the sendall call blocks waiting for some data to be added to the send buffer, causing the recv call to block in turn. What's going on here? Thanks for reading!

• SQL Average Data Based on Distance

  - by jsmith

  I'm pretty new to SQL. I have a database with records based on road/milepoints. My goal is to get an average value every 52.8 ft along the road. My related table has data every 15 ft, this table of course has a foreign key relating it to the primary table. If I wanted to pull out the average value every 52.8 ft, along a given milepost, how would I go about this? Example Data: RecID Begin_MP End_MP 100 0 0.56 RecID MP Value1 Value2 100 0 159 127.7 100 0.003 95.3 115.3 100 0.006 82.3 107 100 0.009 56.5 74.5 100 0.011 58.1 89.1 100 0.014 95.2 78.8 100 0.017 108.9 242.5 100 0.02 71.8 73.3 100 0.023 84.1 80.2 100 0.026 65.5 66.1 100 0.028 122 135.8 100 0.031 99.9 230.7 100 0.034 95.7 111.5 100 0.037 127.3 74.3 100 0.04 140.7 543.1 The first Data is an example of a Road. The second subset of data are the values I need to query out every 52.8 ft. Thank you

• JTable filled with database data is not being updated when columns are reordered.

  - by marionmaiden

  I have a JTable filled with data of a table of my database (so I used ResultSetTableModel) and using TableRowSorter to sort the rows, as I click in one column of the JTable. The data is displayed in the jTable without problems; But when I sort the JTable by some column table (for example, sorting it by the primary key value), and edit some cell from the sorted jTable, the value changed is the old cell that were in that position before the ordenation of the column. For example: Suppose I have a table with 2 columns - name and age. My table has the following data: c 1 b 2 a 3 when I order i by name in the JTable, it becomes like this a 3 b 2 c 1 if I edit the value "1", after the edition, the table becomes like this a 1 b 2 c 1 It seems that the positions are not being updated in the JTable, and the values are edited considering their original positions.

• Jquery Live Validation

  - by sico87

  Hello Everyone, After having a search around I could not find exactly what I want, I am looking to validate a form client side using the Jquery library and some form of validation plugin. I was hoping that some one could advise me on whether there are any validation plugins out there that do not use generic error messages, as my form is laid out with no room for these errors, and I also I want the validator to to for correct content as well. Basically I want to be able to check the field on each key press and blur and if the fields validates for it to gain a green border, and if it does not validate for it to gain a red border, any one know of a plugin that can do this? Thanks sico87

• Sorting nested hash in ruby

  - by Rabbott

  Provided the following ruby hash: { cat: { 1: 2, 2: 10, 3: 11, 4: 1 }, wings: { 1: 3, 2: 5, 3: 7, 4: 7 }, grimace: { 1: 4, 2: 5, 3: 5, 4: 1 }, stubborn: { 1: 5, 2: 3, 3: 7, 4: 5 } } How can I sort the hash by the sum of 'leaf' excluding "4", for instance the value to compare for "cat" would be (2 + 10 + 11) = 23, the value for "wings" would be (3 + 5 + 7) = 15 so if I was comparing just those two they would be in the correct order, highest sum on top. It is safe to assume that it will ALWAYS be {1: value, 2: value, 3: value, 4: value} as those are keys for constants I have defined. It is also safe to assume that I will only ever want to exclude the key "4", and always use the keys "1", "2", and "3"
