• How do I prove to a client/advertiser that my site's analytics numbers are what I say they are?

  - by Bryson

  I have been asked to provide recommendations on "Verified Analytics" for the next iteration of my company's site. Verified to mean that when we sell ad space, it's based on a number of page-views, and the people who buy that space want a way to verify that the numbers we give them are the actual numbers we're delivering. I have turned to The Google and the only services I can find for this sort of thing revolve around Google Analytics and the sale of a domain name. I export my analytics numbers to a PDF, have Google email the PDF to my auctioneer, and they look for signs of tampering. If no signs of tampering are found they put a little "Verified" badge on the domain auction. (Here) Other than this, and something similar on another domain sales site, I haven't found anything like what I've been asked to find. Currently we are using Google Analytics, however I've been also asked to recommend a replacement for that based on the ability to be verified. I'd rather just stick with Google Analytics since we also use Google for advertising.

• Have you ever turned-down morally questionable or unethical web work?

  - by louism

  i'm just wondering if you guys have ever had a situation where you were offered a web development project which you turned down because you felt it was unethical or morally questionable. i've only had this once. i was offered a contract to develop a website for a meat abattoir (i.e. slaughterhouse). what's the problem you may ask? i'm vegetarian. i know, it's not an egregious dilemma, but it just didn't seem right to me. i have a female graphic designer friend who declined to work on a sex toys website where she was working at the time. funny thing is, it wouldn't bother me to work on a porn site (as long as it wasn't anything shifty - e.g. dwarfs + donkeys, that sort of thing). anyone else ever had a similar experience?

• Matching First Alphanumeric Character skipping (The |An? )

  - by TheLizardKing

  I have a list of artists, albums and tracks that I want to sort using the first letter of their respective name. The issue arrives when I want to ignore "The ", "A ", "An " and other various non-alphanumeric characters (Talking to you "Weird Al" Yankovic and [dialog]). Django has a nice start '^(An?|The) +' but I want to ignore those and a few others of my choice. I am doing this in Django, using a MySQL db with utf8_bin collation. EDIT Well my fault for not mentioning this but the database I am accessing is pretty much ready only. It's created and maintained by Amarok and I can't alter it without a whole mess of issues. That being said the artist table has The Chemical Brothers listed as The Chemical Brothers so I think I am stuck here. It probably will be slow but that's not so much of a concern for me as it's a personal project.

• Creating managed file transfer software in java

  - by Shekhar

  Hello, I have been asked to do some POC on how we can provide a software solution which will be able to manage files. Manage files means it will be able to move files from source to destination servers. The client gave us 4 page document detailing what sort of software they are looking for. They dont want to use existing commercial softwares. They want to build their own customizable software. Has anybody worked on this type of project? Please provide your inputs on how should i approach this project. The software should be platform independent and should be built in java.

• Installing Hudson remotely?

  - by Dissonant

  I'm trying to install Hudson on a server. The article here says to just do java -jar hudson.war and it should install to the server. This is pretty straightforward to do on a local computer, but I want to do it on a remote website host that I manage via cPanel. So how on earth do I do this? I really am a newb when it comes to this sort of thing... Also, obviously I require the JRE to do this. How do you install the JRE on a remote website host via cPanel? I don't even know where to get started... Thanks.

• How to have multiple paths display URL as root

  - by Verdi Erel Ergün

  I want users#new and tasks#index to display as the root path URL, i.e. / When a user logs in on the path users#new (set as root) they are redirected to tasks#index and URL does not change. Can this be done in the routes.rb file? This is my routes.rb file: Todo::Application.routes.draw do resources :sessions resources :subscriptions resources :users resources :tasks do collection do post :sort end end root :to => "users#new" match "sessions#new" => "tasks#index" match "sessions#" => "tasks#index"

• Disabling mouse movement and clicks altogether in c#

  - by ThaNerd

  At work, i'm a trainer. I'm setting up lessons to teach people how to "do stuff" without a mouse... Ever seen people click "login" textbox, type, take the mouse, click "password", type their password, then take the mouse again to click the "connect" button beneath ? So i'll teach them how to do all that without a mouse (among many other things, of course) At the end of the course, i'll make them pass a sort of exam. So i'm building a little wizard based app in which i present some simili-real-life examples of forms to fill in, but i want to disable their mouse programatically while they do this test. However, further in the wizard, i'll have to let them use their mouse again. Is there a -- possibly easy -- way to just disable the mouse for a while, and re-enable it later on? I'm on C# 2.0, programming under VC# 2k5, if that matters

• Lightweight PHP server to bundle with application?

  - by munchybunch

  Does there exist some sort of PHP server that can be bundled with a locally-deployed application? It sounds wonky, but the end result is I can't use a remote web server to do anything. Clients will be downloading a package, and the plan is to use a Java backend that reads from a flat file. The flat file contains settings and is modified through a GUI written in HTML/JS, and this is where the server would come in. The forms in HTML should be able to submit to the server, which does a simple file write to the flat file. Is there any simple, lightweight server that has that simple feature? When running the executable for the application, it would start the installation process for the server before moving the web GUI files to the appropriate locations. Note that I'm doing this for a client, so I can't quite change the reqs and would rather not discuss their effectiveness. I would be ever thankful if people had suggestions for the server though!

• Intersection of sets Mongodb

  - by afvasd

  Hi everyone I am new to mongo, this is my db design: product := { name: str group: ref, comments: [ ref, ref, ref, ref ] } comments := { ... a bunch of comments stuff } tag := { _id: int, #Need this for online requests tag: str, products: [ {product: ref, score: float}, ... ], comments: [ {comment: ref, score: float}, ...], } So my usage pattern is: GIVEN a product, find comments that have certain tag and sort them accordingly. My current approach involves: Look for that tag object that has tag=myTag pull all the comments out, sorted look for that product where product.name=myProduct pull all the comments out (which are dbrefs by the way) loop through the result of 2, and checking if they are in 4, (this I can do a limit 10) etc. It's pretty inefficient. Any better methods?

• How to reduce java concurrent mode failure and excessive gc

  - by jimx

  In Java, the concurrent mode failure means that the concurrent collector failed to free up enough memory space form tenured and permanent gen and has to give up and let the full stop-the-world gc kicks in. The end result could be very expensive. I understand this concept but never had a good comprehensive understanding of A) what could cause a concurrent mode failure and B) what's the solution?. This sort of unclearness leads me to write/debug code without much of hints in mind and often has to shop around those performance flags from Foo to Bar without particular reasons, just have to try. I'd like to learn from developers here how your experience is. If you had previous encountered such performance issue, what was the cause and how you addressed it? If you have coding recommendations, please don't be too general. Thanks!

• Adobe Flex + Air or Java + JavaFX 2.0?

  - by kuyapangu

  Hey guys! I'm looking into a cloud-computing related career. I've recently graduated from school and have been meaning to study a new programming language. From what I understand, I need to get into RIA development for this. Flex and Java have certainly caught my attention, but I am torn as to whether focus on Flex then continue with Air, or study Java first and see how JavaFX 2.0 pans out, and then continue with Flex thereafter. I've no previous experience with either, and I'm sort of giving myself something like two years or so to learn. What do guys think? Thanks for the feedback! :)

• Local sites not displaying in VirtualBox when using Django's local development server?

  - by littlejim84

  Hello. I develop web applications using Django on Mac OSX 10.6. I use Django's built in local development server which I run on my computer's IP (such as: http://192.168.0.11:8001/). I test my applications in Firefox, Safari and Chrome and all display fine. I use Sun's VirtualBox with 3 different instances of Windows XP that have IE6, IE7 and IE8 on them. For whatever reason, these sometimes just don't display the Django sites. They come up with 'The page cannot be displayed'. Eight times out of ten, they display fine and function normally but for no reason at all they won't display. Sometimes restarting Django's local development server from the Terminal will fix the problem, sometimes it won't. Is there some sort of VirtualBox settings or Django settings that I need to set to ensure smooth operation of this? Am I overlooking something? Has anyone else had these problems?

• select n largest using LINQ

  - by Mathias

  This is likely a novice question about LINQ, but assuming I have a set of Items with a DateTime property, one date having at most one item, how would I go about selecting the N most recent items from a date of reference, that is, the N items which have a date smaller that the requested date, and the largest date? My naive thought would be to first select items with a date smaller than the reference date, sort by date, and select the N first items from that subset. var recentItems = from item in dataContext.Items where item.Date<=date orderby item.Date descending select item; var mostRecentItems = recentItems.Take(5).ToList(); Is this the "right" way to do it, or are there obviously better ways to achieve my goal?

• How to do custom jquery lives in 1.4.1?

  - by chobo2

  Hi I been sort of using jquery livequery plugin and jquery live together. However now that I am using 1.4 it seems jquery livequery is not working 100%. So I am not sure how to tackle this problem I have this in livequery $('#Description').livequery(function () { $('#Description').htmlarea({ toolbar: [ ["bold", "italic", "underline", "strikethrough", "|", "subscript", "superscript"], ["increasefontsize", "decreasefontsize"], ["orderedlist", "unorderedlist"], ["indent", "outdent"], ["link", "unlink"] ] }); }); So everytime I loaded up my page. It would actually run that code in the livequery and display and if I went to another ajax tab and come back it would go into this again. Now I am not sure how to change it to .live() jquery 1.4 since I just tried to do this $('#Description').live(function () { $('#Description').htmlarea({ toolbar: [ ["bold", "italic", "underline", "strikethrough", "|", "subscript", "superscript"], ["increasefontsize", "decreasefontsize"], ["orderedlist", "unorderedlist"], ["indent", "outdent"], ["link", "unlink"] ] }); }); and it does not seem to work. the plugin is not binded and the rich html editor is not displayed.

• How do I handle TODO comments in VisualStudio 2010?

  - by Ivan

  I'd like Visual Studio to list all lines having "TODO: " in their beginning (usually after a comment sign which may vary depending on the file type) that can be found in any textual file in solution (may it be C#, VB, F#, T-SQL, ASPX, XAML or just TXT) in a special panel showing what's written in the line right to "TODO: ", project name (I use to contain many projects in one solution), file name, line number, code block name (like class and method) if possible. Do you know of such an extension or maybe VisualStudio has this feature built-in somewhere? For example NetBeans has a sort of out-of-the-box.

• Sqlalchemy layout with WSGI application

  - by TheDude

  I'm working on writing a small WSGI application using Bottle and SqlAlchemy and am confused on how the "layout" of my application should be in terms of SqlAlchemy. My confusion is with creating engines and sessions. My understanding is that I should only create one engine with the 'create_engine' method. Should I be creating an engine instance in the global namespace in some sort of singleton pattern and creating sessions based off of it? How have you done this in your projects? Any insight would be appreciated. The examples in the documentation dont seem to make this entirely clear (unless I'm missing something obvious). Any thoughts?

• Add C pointer to NSMutableArray

  - by Georges Oates Larsen

  I am writing an Objective-C program that deals with low level image memory. I am using ANSI-C structs for my data storage -- Full blown objects seem overkill seeing as the data I am storing is 100% data, with no methods to operate on that data. Specifically, I am writing a customizable posterization algorithm which relies on an array of colors -- This is where things get tricky. I am storing my colors as structs of three floats, and an integer flag (related to the posterization algorithm specifically). Everyhting is going well, except for one thing... [actual question] I can't figure out how to add pointers to an NSMutableArray! I know how to add an object, but adding a pointer to a struct seems to be more difficult -- I do not want NSMutableArray dereferencing my pointer and treating the struct as some sort of strange object. I want NSMutableArray to add the pointer its self to its collection. How do I go about doing this? Thanks in advance, G

• How to order the items in a nested LINQ-provided collection

  - by Carson McComas

  I've got a (SQL Server) database table called Category. And another database table called SubCategory. SubCategory has a foreign key relationship to Category. Because of this, thanks to LINQ, each Cateogory has a property called SubCategories and LINQ is nice enough to return all the SubCategories associated with my Category when I grab it. If I want to sort the Categories alphabetically, I can just do: return db.Categories.OrderBy(c => c.Name); However, I have no idea how to order the SubCategories collection inside each Category. My goal is to return a collection of Categories, where all of the SubCategory collections inside of them are ordered alphabetically by Name.

• Trapping events within list box item templates in WPF

  - by AC

  I've got listbox that employs an item template. Within each item in the list, as defined in the template there is a button. When the user clicks the button I change a value in the data source that defines the sort order of the list. Changing the datasource is not a problem as this is working just fine within my application template. However my next step is to reload the listbox with the new sorted data source. I've tried doing this from the tempalte but it apparently doesn't have access (or I can't figure out how to get access) to the parent elements so I can reset the .ItemSource property with a newly sorted data source. Seems like this is possible but the solution is eluding me :(

• jQuery - Slideshow with different sized images and text

  - by NicoJuicy

  I need some sort of slideshow, with text (something like moving boxes would be nice). I have tried several, but i'm always having problems with different sized images (the images can be for eg. 500px x 300px, but the next one can be 500px, 300px), this gives some problems with the pictures ... I hope you understand what i mean. It's very irritating to find a good jquery plugin that can deal with this problem... :( Can anyone find me a good working one or an alternative to jQuery?

• How to apply images conditionally using entries and categories?

  - by Sergio Acosta

  Using version 2.5.3 of ExpressionEngine, I have a list of products displayed by category, but I need the premium products among this list being featured with a small star image. How do you call conditionally this little stars besides the {title}? At the moment this code shows stars for all products and that is not ideal. <ol class="voices-list"> {exp:channel:entries channel="product" orderby="title" sort="asc" category="2&6" dynamic="no"} <li><a href="{page_url}">{title}<img class="feature_icon medium" src="{root_url}img/audio/smallstar.png" alt="star"></a></li> {/exp:channel:entries} </ol> I need your help, please.

• Generating Running Sum of Ratings in SQL

  - by Koobz

  I have a rating table. It boils down to: rating_value created +2 april 3rd -5 april 20th So, every time someone gets rated, I track that rating event in the database. I want to generate a rating history/time graph where the rating is the sum of all ratings up to that point in time on a graph. I.E. A person's rating on April 5th might be select sum(rating_value) from ratings where created <= april 5th The only problem with this approach is I have to run this day by day across the interval I'm interested in. Is there some trick to generating a running total using this sort of data? Otherwise, I'm thinking the best approach is to create a denormalized "rating history" table alongside the individual ratings.

• Genetic programming in c++, library suggestions?

  - by shuttle87

  I'm looking to add some genetic algorithms to an Operations research project I have been involved in. Currently we have a program that aids in optimizing some scheduling and we want to add in some heuristics in the form of genetic algorithms. Are there any good libraries for generic genetic programming/algorithms in c++? Or would you recommend I just code my own? I should add that while I am not new to c++ I am fairly new to doing this sort of mathematical optimization work in c++ as the group I worked with previously had tended to use a proprietary optimization package. We have a fitness function that is fairly computationally intensive to evaluate and we have a cluster to run this on so parallelized code is highly desirable. So is c++ a good language for this? If not please recommend some other ones as I am willing to learn another language if it makes life easier. thanks!
