• uploadify scriptData problem

  - by elpaso66

  Hi, I'm having problems with scriptData on uploadify, I'm pretty sure the config syntax is fine but whatever I do, scriptData is not passed to the upload script. I tested in both FF and Chrome with flash v. Shockwave Flash 9.0 r31 This is the config: $(document).ready(function() { $('#id_file').uploadify({ 'uploader' : '/media/filebrowser/uploadify/uploadify.swf', 'script' : '/admin/filebrowser/upload_file/', 'scriptData' : {'session_key': 'e1b552afde044bdd188ad51af40cfa8e'}, 'checkScript' : '/admin/filebrowser/check_file/', 'cancelImg' : '/media/filebrowser/uploadify/cancel.png', 'auto' : false, 'folder' : '', 'multi' : true, 'fileDesc' : '*.html;*.py;*.js;*.css;*.jpg;*.jpeg;*.gif;*.png;*.tif;*.tiff;*.mp3;*.mp4;*.wav;*.aiff;*.midi;*.m4p;*.mov;*.wmv;*.mpeg;*.mpg;*.avi;*.rm;*.pdf;*.doc;*.rtf;*.txt;*.xls;*.csv;', 'fileExt' : '*.html;*.py;*.js;*.css;*.jpg;*.jpeg;*.gif;*.png;*.tif;*.tiff;*.mp3;*.mp4;*.wav;*.aiff;*.midi;*.m4p;*.mov;*.wmv;*.mpeg;*.mpg;*.avi;*.rm;*.pdf;*.doc;*.rtf;*.txt;*.xls;*.csv;', 'sizeLimit' : 10485760, 'scriptAccess' : 'sameDomain', 'queueSizeLimit' : 50, 'simUploadLimit' : 1, 'width' : 300, 'height' : 30, 'hideButton' : false, 'wmode' : 'transparent', translations : { browseButton: 'BROWSE', error: 'An Error occured', completed: 'Completed', replaceFile: 'Do you want to replace the file', unitKb: 'KB', unitMb: 'MB' } }); $('input:submit').click(function(){ $('#id_file').uploadifyUpload(); return false; }); }); I checked that other values (file name) are passed correctly but session_key is not. This is the decorator code from django-filebrowser, you can see it checks for request.POST.get('session_key'), the problem is that request.POST is empty. def flash_login_required(function): """ Decorator to recognize a user by its session. Used for Flash-Uploading.

• Is make -j distcc possible to scale over 5 times?

  - by holmes

  Since distcc cannot keep states and just possible to send jobs and headers and let those servers to use only the data just sent and preprocess and compile, I think the lastest distcc has problem in scalability. In my local build environment which has appx. 10,000 c/c++ files to build, I could only make 2 times faster than not using distcc (but using make -j) when having 20 build servers. What do you think is the problem? If anyone has achieved scalability more than 10 - 20 times using make -j and distcc, please let me know. The following product claims that it is impossible to scale make -j and distcc faster than 5 times. http://www.electric-cloud.com/products/electricaccelerator.php I think this can be improved by: Letting the distccd server to maintain sessions Tied to those sessions, they will cache their own header directories Preprocess will be done demand base from the distccd server This will be done through a LD_PRELOADed library libdistcc.so which will replace stat/open syscalls and fetches the header files over network. ... Has anyone done this kind of thing?

  Hi. I have ceated several django apps and stuffs for my own fund and so far everything has been working fine. Now i just created new project (django 1.2.1) and have run into trouble from 1st moments. I created new app - game and new model Game. i created admin.py and put related stuff into it.

• StreamReader ReadToEnd() after HttpWebRequest EndGetResponse() - most scalable?

  - by frankadelic

  I am calling a RESTful web service in the back-end of some ASP.NET pages. I am using ASP.NET asynchronous pages, so under the hood I am using the methods: HttpWebRequest BeginGetResponse() and HttpWebRequest EndGetResponse() The response string in my case is always a JSON string. I use the following code to read the entire string: using (StreamReader sr = new StreamReader(myHttpWebResponse.GetResponseStream())) { myObject.JSONData = sr.ReadToEnd(); } Is this method OK in terms of scalability? I have seen other code samples that instead retrieve the response data in blocks using Read(). My primary goal is scalability, so this back-end call can be made across many concurrent page hits. Thanks, Frank

• 'memcache-client' problem - app can't load the gem

  - by Max Williams

  Hi all - i'm trying to get memcached and the Interlock plugin working with a new rails app. The weird thing is that they both work fine in another app on the same machine and i can't figure out the difference that's stopping this app. The new app is rails 2.3.4 and the old one is 2.2.2 in case that's a factor. When the app starts, i get a warning from interlock: `install_memcached':Interlock::ConfigurationError: 'memcache-client' client requested but not installed. Try 'sudo gem install memcache-client'. Now, i have memcache-client installed: $> gem list | grep memcache memcache-client (1.7.8) The gem is in /var/lib/gems/1.8, which is in my GEM_PATH variable. On a bit of further investigation, the above error is raised by interlock when it refers to the MemCache class, which doesn't exist and so raises an 'anonymous module' error. So, ultimately, the problem is that MemCache isn't loaded. I have a memcached.yml in my config folder (below) however. I'm stuck - any advice anyone? #contents of config/memcached.yml defaults: namespace: millionaire #sessions: true sessions: false client: memcache-client with_finders: true development: servers: - 127.0.0.1:11211 production: servers: - 127.0.0.1:11211

• Using datetime float representation as primary key

  - by devanalyst

  From my experience I have learn that using an surrogate INT data type column as primary key esp. an IDENTITY key column offers better performance than using GUID or char/varchar data type column as primary key. I try to use IDENTITY key as primary key wherever possible. But recently I came across a schema where the tables were horizontally partitioned and were managed via a Partitioned view. So the tables could not have an IDENTITY column since that would make the Partitioned View non updatable. One work around for this was to create a dummy 'keygenerator' table with an identity column to generate IDs for primary key. But this would mean having a 'keygenerator' table for each of the Partitioned View. My next thought was to use float as a primary key. The reason is the following key algorithm that I devised DECLARE @KEY FLOAT SET @KEY = CONVERT(FLOAT,GETDATE())/100000.0 SET @KEY = @EMP_ID + @KEY Heres how it works. CONVERT(FLOAT,GETDATE()) gives float representation of current datetime since internally all datetime are represented by SQL as a float value. CONVERT(FLOAT,GETDATE())/100000.0 converts the float representation into complete decimal value i.e. all digits are pushed to right side of ".". @KEY = @EMP_ID + @KEY adds the Employee ID which is an integer to this decimal value. The logic is that the Employee ID is guaranteed to be unique across sessions since an employee cannot connect to an application more than once at the same time. And for the same employee each time a key will be generated the current datetime will be unique. In all an unique key across all employee sessions and across time. So for Emp Ids 11 and 12, I have key values like 12.40046693321566357, 11.40046693542361111 But my concern whether float data type as primary key offer benefits compared to choosing GUID or char/varchar as primary keys. Also important thing is because of partitioning the float column is going to be part of a composite key.

• Linking session state between servlets and EJBs?

  - by wilth

  Hello, I have servlets (in a web module) that access stateless EJB beans (in an EJB module). The EJB module is built using SEAM. Users can have different roles and the EJB services check this using Seam's Identity. I also use a customized Authenticator (although this might not be relevant here). I noticed problems with this approach and I'm suspecting that the session context in the servlets is not "linked" with the session context in the EJB beans. What I think happens is something like: User Joe access servlet A and is assigned Session W1. Servlet A calls a login function on an EJB, using the EJB session E1. Later, user Mary accesses servlet A and is assigned Session W2. When calling the EJBs, however, the EJB session E1 is used and therefore Mary is authenticated as Joe. What also happens is that when Joe is calling the servlet twice in rapid succession, the same session W1 is used, but two different sessions E1 and E2 in the business layer, causing errors. I might be wrong in my suspicion, but maybe I'm actually expecting these "sessions" to be linked together while they in fact are not. If this is true, is there any way of achieving this? I could - of course - use stateful beans and save the authentication information in the beans, but this would break the "Identity" concept of Seam (and in general, it would be preferable to be able to use the Session context in my EJB beans). Any help and pointers are very welcome - thanks! Technology: EJB3, Seam 2.1.2. The servlets are actually the server-side of a GWT app, although I don't think this matters much. I'm using JBoss 5.

• Is there a HIPAA certification that would be helpful to programmers?

  - by Aequitarum Custos

  I work at a Medical Billing company that's software handles many facets of the centers practice, including patients, treatments, etc. To be frank, the only thing I know about HIPAA is security is paramount. I was wondering if there were any training courses with an earned certification proving knowledge/experience that I could use to increase my worth to the company, and give them a selling point (we have HIPAA certified employees). I did a Google search and found this site, but it does not appear legitimate, and I'm trying to avoid any of those fake certification/degree sites. Does anyone know of any recognized and legitimate (preferably government sponsored) HIPAA certifications useful to programmers? If state is a factor, I live in Oklahoma.

• Rreport / LaTeX quality output package

  - by aL3xa

  I'm looking for some LaTeX template for creating quality output. On R-bloggers I've bumped on Frank Harrel's Rreport package. Due to my, quite modest LaTeX abilities, only user-friendly (and noob-friendly) interface should suffice. Here's a link to an official website. I'm following the instructions, but I cannot manage to install an app. I use Ubuntu 9.10, R version is 2.10.1 (updated regularly from UCLA's CRAN server)... of course, cvs is installed on my sistem. Now, I'd like to know is there some user-friendly LaTeX template package (Sweave is still to advanced/spartan for me). I'm aware that my question is quite confounding, but brief glance on examples on Rreport page should give you a hint. I'm aware that LaTeX skills are a must, but just for now I need something that will suite my needs (as a psychological researcher). Is there any pandan for Rreport package?

• Calling a SLSB with Seam security from a servlet

  - by wilth

  Hello, I have an existing application written in SEAM that uses SEAM Security (http://docs.jboss.org/seam/2.1.1.GA/reference/en-US/html/security.html). In a stateless EJB, I might find something like this: @In Identity identity; ... if(identity.hasRole("admin")) throw new AuthException(); As far as I understand, Seam injects the Identity object from the SessionContext of the servlet that invokes the EJB (this happens "behind the scenes", since Seam doesn't really use servlets) and removes it after the call. Is this correct? Is it now possible to access this EJB from another servlet (in this case, that servlet is the server side of a GWT application)? Do I have to "inject" the correct Identity instance? If I don't do anything, Seam injects an instance, but doesn't correctly correlate the sessions and instances of Identity (so the instances of Identity are shared between sessions and sometimes calls get new instances etc.). Any help and pointers are very welcome - thanks! Technology: EJB3, Seam 2.1.2. The servlets are actually the server-side of a GWT app, although I don't think this matters much. I'm using JBoss 5.

• Importing fixtures with foreign keys and SQLAlchemy?

  - by Chris Reid

  I've been experimenting with using fixture to load test data sets into my Pylons / PostgreSQL app. This works great except that it fails to properly create foreign keys if they reference an auto increment id field. My fixture looks like this: class AuthorsData(DataSet): class frank_herbert: first_name = "Frank" last_name = "Herbert" class BooksData(DataSet): class dune: title = "Dune" author_id = AuthorsData.frank_herbert.ref('id') And the model: t_authors = sa.Table("authors", meta.metadata, sa.Column("id", sa.types.Integer, primary_key=True), sa.Column("first_name", sa.types.String(100)), sa.Column("last_name", sa.types.String(100)), ) t_books = sa.Table("books", meta.metadata, sa.Column("id", sa.types.Integer, primary_key=True), sa.Column("title", sa.types.String(100)), sa.Column("author_id", sa.types.Integer, sa.ForeignKey('authors.id')) ) When running "paster setup-app development.ini", SQLAlchemey reports the FK value as "None" so it's obviously not finding it: 15:59:48,683 INFO [sqlalchemy.engine.base.Engine.0x...9eb0] INSERT INTO books (title, author_id) VALUES (%(title)s, %(author_id)s) RETURNING books.id 15:59:48,683 INFO [sqlalchemy.engine.base.Engine.0x...9eb0] {'author_id': None, 'title': 'Dune'} The fixture docs actually warn that this might be a problem: "However, in some cases you may need to reference an attribute that does not have a value until it is loaded, like a serial ID column. (Note that this is not supported by the SQLAlchemy data layer when using sessions.)" http://farmdev.com/projects/fixture/using-dataset.html#referencing-foreign-dataset-classes Does this mean that this is just not supported with SQLAlchemy? Or is it possible to load the data without using SA "sessions"? How are other people handling this issue?

  - by ilnur777

  Hi, guys!

• Django Image Upload: IOErrno2 Could not find path -- and yet it's saving the image there anyway?

  - by Rob

  I have an issue where the local version of django is handling image upload as expected but my server is not. Note: I am using a Django Container on MediaTemple.net (grid server) Here is my code. def view_settings(request): <snip> if request.POST: success_msgs = () mForm = MainProfileForm(request.POST, request.FILES, instance = mProfile) pForm = ChangePasswordForm(request.POST) eForm = ChangeEmailForm(request.POST) if mForm.is_valid(): m = mForm.save(commit = False) if mForm.cleaned_data['avatar']: m.avatar = upload_photo(request.FILES['avatar'], settings.AVATAR_SAVE_LOCATION) m.save() success_msgs += ('profile pictured updated',) <snip> def upload_photo(data,saveLocation): savePath = os.path.join(settings.MEDIA_ROOT, saveLocation, data.name) destination = open(savePath, 'wb+') for chunk in data.chunks(): destination.write(chunk) destination.close() return os.path.join(saveLocation, data.name) Here's where it gets whacky and I was hoping someone could shed a light on this error, because either a) it's the wrong error code, or b) something is happening with the file before it's completely handled. To recap, the file was actually uploaded to the server in the intended directory - and yet this err msg continues to persist. IOError at /user/settings [Errno 2] No such file or directory: u'/home/user66666/domains/example.com/html/media/images/avatars/DSC03852.JPG' Environment: Request Method: POST Request URL: http://111.111.111.111:2011/user/settings Django Version: 1.0.2 final Python Version: 2.4.4 Installed Applications: ['django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'ctrlme', 'usertools', 'easy_thumbnails'] Installed Middleware: ('django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware') Traceback: File "/home/user6666/containers/django/leonidas/usertools/views.py" in view_settings m.avatar = upload_photo(request.FILES['avatar'], settings.AVATAR_SAVE_LOCATION) File "/home/user666666/containers/django/leonidas/usertools/functions.py" in upload_photo destination = open(savePath, 'wb+')

• What is your longest-held programming assumption that turned out to be incorrect?

  - by Demi

  I am doing some research into common errors and poor assumptions made by junior (and perhaps senior) software engineers. What was your longest-held poor assumption that was eventually corrected? For example: I at one point failed to understand that the size of an integer was not a standard (depends on the language and target). A bit embarrassing to state, but there it is. Be frank: what hard-held belief did you have, and roughly how long did you maintain the assumption? It can be about an algorithm, a language, a programming concept, testing, anything under the computer science domain.

• How do I make PHP's Magic __set work like a natural variable?

  - by Navarr

  Basically, what I want to do is create a class called Variables that uses sessions to store everything in it, allowing me to quickly get and store data that needs to be used throughout the entire site without working directly with sessions. Right now, my code looks like this: <?php class Variables { public function __construct() { if(session_id() === "") { session_start(); } } public function __set($name,$value) { $_SESSION["Variables"][$name] = $value; } public function __get($name) { return $_SESSION["Variables"][$name]; } public function __isset($name) { return isset($_SESSION["Variables"][$name]); } } However, when I try to use it like a natural variable, for example... $tpl = new Variables; $tpl->test[2] = Moo; echo($tpl->test[2]); I end up getting "o" instead of "Moo" as it sets test to be "Moo," completely ignoring the array. I know I can work around it by doing $tpl->test = array("Test","Test","Moo"); echo($tpl->test[2]); but I would like to be able to use it as if it was a natural variable. Is this possible?

• Devise routes /:param not working

  - by Jacob Schatz

  Using devise 2.1.0 I am trying to send the new registration page a PricingPlan model. So in my routes I have: devise_scope :user do delete "/logout" => "devise/sessions#destroy" get "/login" => "devise/sessions#new" get "/signup/:plan" => "devise/registrations#new" end And I override the devise registration controller. With this in my routes.rb to make it work: devise_for :users, :controllers => {:registrations => "registrations"} In my actual Registration controller which overrides Devise's controller I have: class RegistrationsController < Devise::RegistrationsController view_paths = "app/views/devise" def new super @plan = PricingPlan.find_by_name(params[:plan]) end So that the default views still go to devise.... In my new view for the registration controller I call this: <h3>You've chosen the <%= @plan.name %> plan.</h3> And I get this error: undefined method `name' for nil:NilClass Also... in my PricingPlan model: class PricingPlan < ActiveRecord::Base has_many :users And in my User model: class User < ActiveRecord::Base belongs_to :pricing_plan I'm rather new at rails.

• iphone not displaying array variables correctly

  - by Rob

  I was reading a tutorial on how to do a UIPicker and found this code: - (IBAction)buttonPressed { NSInteger row = [userPicker selectedRowInComponent:0]; NSString *selected = [userPickerData objectAtIndex:row]; NSString *title = [[NSString alloc] initWithFormat:@"You selected %a", selected]; UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:@"Thank you for Choosing." delegate:nil cancelButtonTitle:@"You're Welcome" otherButtonTitles:nil]; [alert show]; [alert release]; [title release]; } - (void)viewDidLoad { // [super viewDidLoad]; NSArray *array = [[NSArray alloc] initWithObjects:@"New", @"Frank", @"Bob", @"Thor", nil]; self.userPickerData = array; [array release]; } The UIPicker displays correctly and the variables in the picker also display correctly. When the button is pressed then the alert message does come up but it says, "You selected.." and then it's a bunch of gibberish. Why aren't the array variables being passed correctly?

• How to get DataTable to serialize better?

  - by AngryHacker

  I have the following code that serializes a DataTable to XML. StringWriter sw = new StringWriter(); myDataTable.WriteXml(sw); And this works, however, the serialized XML looks like this: <NameOfTable> <NameOfTable> <ID>1</ID> <Name>Jack</Name> </NameOfTable> <NameOfTable> <ID>2</ID> <Name>Frank</Name> </NameOfTable> </NameOfTable> Is there anyway to change the outer <NameOfTable> to, say, <Records> and the inner <NameOfTable> to <Person>?
