• Estimate gaussian (mixture) density from a set of weighted samples

  - by Christian

  Assume I have a set of weighted samples, where each samples has a corresponding weight between 0 and 1. I'd like to estimate the parameters of a gaussian mixture distribution that is biased towards the samples with higher weight. In the usual non-weighted case gaussian mixture estimation is done via the EM algorithm. Does anyone know an implementation (any language is ok) that permits passing weights? If not, does anyone know how to modify the algorithm to account for the weights? If not, can some one give me a hint on how to incorporate the weights in the initial formula of the maximum-log-likelihood formulation of the problem? Thanks!

• Outlook Folder Browse Dialog???

  - by Ike

  Hello there, I'm hoping someone could help me with a quick point in the right direction. ALL I NEED is the Outlook folder browser dialog call. I am developing some plugins for Outlook using C# and this is a crucial part for both plugins. Hopefully, it is like a standard DialogResult that passes back folder information (selected folder) so that I can use this info for further processing. Can anyone help me? Thanks in advance.

• How to build the ViewModel in MVVM not to violate the Single Responsibility Principle?

  - by Przemek

  Robert Martin says: "There should never be more than one reason for a class to change". Let's consider the ViewModel class which is bound to a View. It is possible (or even probable) that the ViewModel consists of properties that are not really related to each other. For small views the ViewModel may be quite coherent, but while the application gets more complex the ViewModel will expose data that will be subject to change for different and unrelated reasons. Should we worry about the SRP principle in the case of ViewModel class or not?

• Fastest way to call a COM objects method without using a RCW

  - by Nathan W

  I'm trying to find the cleanest and fastest way for calling a COM objects methods. I was using a RCW for the object but every time a new version of the third party COM object comes out its GUID changes which then renders the RCW useless, so I had to change and start using Type mytype = Type.GetTypeFromProgID("MyCOMApp.Application"); so that every time a new version of the COM object comes out I don't have to recomplie and redeploy my app. At the moment I am using refelection like mytype.InvokeMemeber but I feel it is so slow compared to just calling the RCW. How does everyone else tackle the problem of changing 3rd party COM object versions, but still maintaining the speed of a RCW?

• Configuring subdomains for a machine (Win2k8) in a lan

  - by RMS

  I am currently setting up a windows 2008 server to host a website with multiple subdomains, all accessible only within the lan. also, there is no active directory. what I did is : 1 - computer name : 'web' 2 - in IIS, I added a site binding as 'site1.web' to the default web site 3 - added DNS role to the server 4 - added 'web' as principal zone in direct lookup zones (default options) 5 - added CNAME 'site1' From a client machine, in tcpip config I added the ip address of 'web' to the DNS list in addition to the ISP DNS. (client machine ip is from DHCP) Now browsing to 'http://web' or 'http://site1.web' works correctly. My question is, is it possible throught additional steps in the server to have the websites accessible without requiring the DNS config in all the client machines ? thanks in advance

• My rundll32.exe file is corrupt, how do I fix it?

  - by wahle509

  The other day I got a virus on my laptop (Windows XP), but Adaware found it and removed it. Not soon enough though, because it corrupted my rundll32.exe file. Now I can't run almost any application and I have tried to install a couple programs to fix my registry, but I can't even run the install file. What other options do I have besides re-installing my OS?

• How to fix a bad case rattle

  - by C. Ross

  I have a full sized ATX case with several fans, including one on the door/removable side. This fan makes the "door" rattle or vibrate loudly when the fan runs at full speed, such as at startup. I can stop the rattle temporarily by placing my hand on the "door", or pushing an object next to it. Do you have any suggestions for a permanent solution? Note: The "door" in question is a slide out panel with two twist screws at the back to hold it in.

• I need a TSE (The Semware Editor) replacement for Windows / Linux / OS X / Solaris (one to edit them

  - by lexu

  My text and programmers editor of choice, when working on a windows box is TSE (The Semware Editor). It is small, it is fast, it is configurabel, and since I've used it (and it's predecessor QEdit) for over twenty years, my fingers can do the editing on autopilot, while the brain is busy with syntax and design. Do you know of a similar editor preferably one that runs on Windows, Linux and OS X (and Solaris ..) I've tried to use VIM (I know how to use VI even longer thant TSE) but it doesn't feel right.

• manage a hosted file by email

  - by Toc

  I need a service which allows me to edit a hosted text file by email. For example: I write an email to [email protected] with subject "ADD LINE 10" and sending it the mail body is inserted into myfile which is hosted on a server of someservice.ext. Same for "DELETE LINE 12" or "SUBSTITUTE LINE 15". If I write "ECHO FILE" or something similar, the service should send me an email with the updated content of the text file. Does it exist?

• Use jquery to create a multidimensional array

  - by Simon M White

  I'd like to use jquery and a multidemensional array to show a random quote plus the name of the individual who wrote it as a separate item. I'll then be able to use css to style them differently. The quote will change upon page refresh. So far i have this code which combines the quote and the name and person who wrote it: $(document).ready(function(){ var myQuotes = new Array(); myQuotes[0] = "Lorem ipsum dolor sit amet, consectetur adipiscing elit. Donec in tortor mauris. Peter Jones, Dragons Den"; myQuotes[1] = "Curabitur interdum, nibh et fringilla facilisis, lacus ipsum pulvinar mauris, eu facilisis justo arcu eget diam. Duis id sagittis elit. Theo Pathetis, Dragons Den"; myQuotes[2] = "Vivamus purus purus, tincidunt et porttitor et, euismod sit amet urna. Etiam sollicitudin eros nec metus pretium scelerisque. James Caan, Dragons Den"; var myRandom = Math.floor(Math.random()*myQuotes.length); $('.quote-holder blockquote span').html(myQuotes[myRandom]); }); any help would be greatly appreciated.

• How to disambiguate a sequence in sql?

  - by Martin

  I have a table of data which represents a series of events that persons do over time, sometimes people do the same thing several times in a row. How to select a result using MS SQL 2008 that shows only disambiguated sequences of those events? Source data: Person Event Time 1 2 1 1 2 20 1 2 33 2 1 34 1 4 43 1 2 44 2 3 45 1 2 46 1 3 50 1 3 55 Result: Person Event 1 2 2 1 1 4 1 2 2 3 1 3

• Problem with nested lambda expressions.

  - by Lehto

  Hey I'm trying to do a nested lambda expression like to following: textLocalizationTable.Where( z => z.SpokenLanguage.Any( x => x.FromCulture == "en-GB") ).ToList(); but i get the error: Member access 'System.String FromCulture' of 'DomainModel.Entities.SpokenLanguage' not legal on type 'System.Data.Linq.EntitySet`1[DomainModel.Entities.SpokenLanguage]. TextLocalization has this relation to spokenlanguage: [Association(OtherKey = "LocalizationID", ThisKey = "LocalizationID", Storage = "_SpokenLanguage")] private EntitySet<SpokenLanguage> _SpokenLanguage = new EntitySet<SpokenLanguage>(); public EntitySet<SpokenLanguage> SpokenLanguage { set { _SpokenLanguage = value; } get { return _SpokenLanguage; } } Any idea what is wrong?

• Uploadify refuses to upload WMV, FLV and MP4 files - SOLVED

  - by Jon Winstanley

  The uploadify plugin for JQuery seems very good and works for most file types. However, it allows me to upload all file types apart from the ones I need! Namely .WMV, .FLV and .MP4 Uploads of any other type work. I have already tried changing the fileExt parameter and also tried removing it altogether. I have testing in Google Chrome, IE7 and Firefox and none work for these file types. I have a ton of local projects already and uploading is not an issue on any other project, I even use the same example files (This is the first time I have used Uploadify) Is there a known reason for this behaviour? EDIT: Have found the issue. I had forgotten to add my usual .htaccess file to the example project.

• MERGE -v- UPSERT

  - by Kevin Ross

  Hi, I have an application I’m writing in access with a SQL server backend. One of the most heavily used parts is where the users selects an answer to a question, a stored procedure is then fired which sees if an answer has already been given, if it has an UPDATE is executed, if not an INSERT is executed. This works just fine but now we have upgraded to SQL server 2008 express I was wondering if it would be better/quicker/more efficient to rewrite this SP to use the new MERGE command. Does anyone have any idea if this is faster than doing a SELECT followed by either an INSERT or UPDATE?

• .NET 3.5 SP1 Code from Network - "The system cannot find the file specified."

  - by DaMoose

  This issue has nothing to do with whether the assemblies have been signed or caspol has been run for the shared network folder. Apparently, the location of the files is the issue, but I cannot find what the real problem is. I have one executable that references 5 dll's. I can run the app from a local drive without any problem. When I run the app from a network share, I get an error stating that "Could not load file or assembly 'homer, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified." If all the files are in the same folder, what is the error really telling me? I should note also that the framework used is 3.5 SP1, which does not require changing code access policy. I had tried that anyhow, and I received the same error in both cases. Thanks, DaMoose

• Cross-Domain iframe communication

  - by Chris

  I have an iframe being created on a page, and the page's domain is being explicitly set to 'xyz.com' but the iframe's domain is defaulting to 'dev.xyz.com', which is the actual domain i'm developing for. The problem is, when I try to access that iframe via iframe.contentWindow.document, it fails due to the difference in domain. I've tried setting the iframe's src to a file with document.domain = 'xyz.com' but that doesn't seem to be doing the trick... Any ideas?

• Uploading images from Flex to Rails using Paperclip

  - by 23tux

  Hi everyone, I'm looking for a way to upload images that were created in my flex app to rails. I've tried to use paperclip, but it don't seem to work. I've got this tutorial here: http://blog.alexonrails.net/?p=218 The problem is, that they are using a FileReference to browse for files on the clients computer. They call the .upload(...) function and send the data to the upload controller. But I'm using a URLLoader to upload a image, that is modified in my Flex-App. First, here is the code from the tutorial: private function selectHandler(event:Event):void { var vars:URLVariables = new URLVariables(); var request:URLRequest = new URLRequest(uri); request.method = URLRequestMethod.POST; vars.description = "My Description"; request.data = vars; var uploadDataFieldName:String = 'filemanager[file]'; fileReference.upload(request, uploadDataFieldName); } I don't know how to set that var uploadDataFieldName:String = 'filemanager[file]'; in a URLLoader. I've got the image data compressed as a JPEG in a ByteArray. It looks like this: public function savePicture():void { var filename:String = "blubblub.jpg"; var vars:URLVariables = new URLVariables(); vars.position = layoutView.currentPicPosition; vars.url = filename; vars.user_id = 1; vars.comic_id = 1; vars.file_content_type = "image/jpeg"; vars.file_file_name = filename; var rawBytes:ByteArray = new JPGEncoder(75).encode(bitmapdata); vars.picture = rawBytes; var request:URLRequest = new URLRequest(Data.SERVER_ADDR + "pictures/upload"); request.method = URLRequestMethod.POST; request.data = vars; var loader:URLLoader = new URLLoader(request); loader.addEventListener(Event.COMPLETE, savePictureHandler); loader.addEventListener(IOErrorEvent.IO_ERROR, errorHandlerUpload); loader.load(request); } If I set the var.picture URLVariable to the bytearray, then I get the error, that the upload is nil. Here is the Rails part: Picture-Model: require 'paperclip' class Picture < ActiveRecord::Base # relations from picture belongs_to :comic belongs_to :user has_many :picture_bubbles has_many :bubbles, :through => :picture_bubbles # attached file for picture upload -> with paperclip plugin has_attached_file :file, :path => "public/system/pictures/:basename.:extension" end and the picture controller with the upload function: class PicturesController < ApplicationController protect_from_forgery :except => :upload def upload @picture = Picture.new(params[:picture]) @picture.position = params[:position] @picture.comic_id = params[:comic_id] @picture.url = params[:url] @picture.user_id = params[:user_id] if @picture.save render(:nothing => true, :status => 200) else render(:nothing => true, :status => 500) end end end Does anyone know how to solve this problem? thx, tux

• Way to turn on keyboard's caps-lock light without actually turning on caps-lock?

  - by cksubs

  I'm writing a program that uses caps-lock as a toggle switch. It would be nice to set the LED of the key to show that my program is on or off, like the capslock key does naturally. I know that I could just SendInput('Capslock'); or whatever to actually turn caps-lock on and off. But my app is a typing program, and I don't want to have to deal with translating the all-caps keys that turning it on would give me into their lower/upper cases. I might go that route eventually, but not for this version. I would however be interested in just turning on the LED light WITHOUT actually turning on caps-lock. Is there any way to do that? Thank you.

• Starting a cocos2d game with initial gameplay as background

  - by boz

  Hi All, Id like to start my game, with the initial game play layout as the background, with a buttons layer over the top with maybe 'Tap to start' and a high score etc. and similarly, when the game finishes, id like to just 'pause' the final game play layout and overlay a game over menu of sorts. I tried calling [[CCDirector sharedDirector] pause] as the last line of the appDidFinishLaunching which didnt seem to have any effect. Is there a better way trying to do this? I dont really like my initial approach.

• Infopath - changing sql servers

  - by ScottStonehouse

  I have an InfoPath form which has sort of a master-detail pattern, with two tables in the underlying main datasource. I am trying to migrate this to a new SQL Server - same database, just moved from a SQL2005 machine to a SQL2008 machine. If I change the servername, it also wants me to change the database and tables. If I select the same database and master table, the bindings are maintains for the master table. But there doesn't appear to be a way to select multiple tables when you change the datasource, so you lose the detail bindings. Am I missing something - I'm pretty new to InfoPath.

• jQuery drawing and modifying lines and positions

  I want to allow people to select a feature region on an image using jQuery. This should work similarly to the Facebook tagger except once someone "tags" an area of the image an ellipse should appear with the ability for the user to rotate and scale it. How can I achieve this using jQuery?

• Motherboard memory question

  - by JERiv

  I am currently drawing up specs on a new workstation for my office. I am considering the Asus P6X58D for a motherboard. This board's specs list it as supporting 24 gigs of memory. Suppose I were to use six four gig memory cards and then two video cards with 1 gig of memory apiece. Is the maximum supported memory similar to how 32 bit operating systems only have enough address space for 4 gigs of memory? Simply: Will the board post? If so, will the system be able to address all the memory, both the 24 gigs on the ddr3 bus and the 3 gigs on the graphics card?
