• How to call a WCF singleton service within a WCF singleton service without hanging?

  - by Michael Hedgpeth

  I have two services, one that calls another. Both are marked as singletons as follows: [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single, ConcurrencyMode = ConcurrencyMode.Multiple)] public class Service : IService And I set these up with a ServiceHost as follows: ServiceHost serviceHost = new ServiceHost(singletonElement); serviceHost.Open(); When the parent service tries to call the child service on the same machine, the parent service hangs, waiting for the child service. I'm already considering moving away from the singleton model, but is there anything wrong with my approach? Is there an explanation for this behavior and a way out of it?

• How to be sure that my MVC project is running on the correct version after upgrade to vs2010?

  - by Stephane

  I just installed visual studio 2010 and upgraded my MVC project (which was running on MVC RC2 in visual studio 2008). visual studio 2010 updated every project file to target the framework 4.0. But the system.web.dll is pointing to C:\Program Files (x86)\Microsoft ASP.NET\ASP.NET MVC 2\Assemblies\System.Web.Mvc.dll in VS2010 object browser, I have every dll showing up in multiple versions as expected (3.5.0.0 and 4.0.0.0) except for the System.Web.Mvc dll which doesn't show any version and points to the path I mentioned above. Isn't this namespace point to the Framework folder like the System.Web namespace? C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\System.Web.dll

• Checking if MySQL Database data does not exist

  - by Ben Sinclair

  I have my songs set-up in my MySQL database. Each song is is either assigned multiple locations or has no locations at all. Only the songs that either have no locations assigned in the database or have the location assigned to the ones specified below should be pulled from the database. Hopefully when you understand my query below it will make sense SELECT s.* FROM roster_songs AS s LEFT JOIN roster_songs_locations AS sl ON sl.song_id = s.id WHERE EXISTS ( SELECT sl2.* FROM roster_songs_locations AS sl2 WHERE s.id != sl2.song_id ) OR ( sl.location_id = '88fb5f94-aaa6-102c-a4fa-1f05bca0eec6' OR sl.location_id = '930555b0-a251-102c-a245-1559817ce81a' ) GROUP BY s.id The query almost works except it pulls out of the database songs that are assigned to sl.location_id's that aren't specified in the above query. I think it has something to do with my EXISTS code picking them up... Any ideas how I can get this to work?

• Relationship Modelling in Core Data

  - by Stevie

  Hi there, I'm fairly new to Objective C and Core Data and have a problem designing a case where players team up one-on-one and have multiple matches that end up with a specific result. With MySQL, I would have a Player table (player primary key, name) and a match table (player A foreign key, player B foreign key, result). Now how do I do this with Core Data? I can easily tie a player entity to a match entity using a relationship. But how do I model the inverse direction for the second player ref. in the match entity? Player Name: Attribute Match: Relationship Match Match Result: Attribute PlayerA: Relationship to Player (<- Inverse to Player.Match) PlayerB: Relationship to Player (<- Inverse to ????) Would be great if someone could give me an idea on this! Thanks, Stevie.

• Java: Parse Australian Street Addresses

  - by bguiz

  Looking for a quick and dirty way to parse Australian street addresses into its parts: 3A/45 Jindabyne Rd, Oakleigh, VIC 3166 should split into: "3A", 45, "Jindabyne Rd" "Oakleigh", "VIC", 3166 Suburb names can have multiple words, as can street names. See: http://stackoverflow.com/questions/1739746/parse-a-steet-address-into-components Has to be in Java, cannot make http requests (e.g. to web APIs). EDIT: Assume that format specified is always followed. I have no issue with spitting incorrectly formatted strings back at the user with a message telling them to follow the format (which I've described above).

• How to exclude read only fields using :input in jquery?

  - by melaos

  hi guys, thus far i've only been using some basic jquery selectors and functions. but i'm looking at this clear form function and i can't figure out how to add it so i can remove hidden inputs and readonly input from getting cleared. can anybody help? thanks. function clearForm(form) { // iterate over all of the inputs for the form // element that was passed in $(':input', form).each(function() { var type = this.type; var tag = this.tagName.toLowerCase(); // normalize case // it's ok to reset the value attr of text inputs, // password inputs, and textareas if (type == 'text' || type == 'password' || tag == 'textarea') this.value = ""; // checkboxes and radios need to have their checked state cleared // but should *not* have their 'value' changed else if (type == 'checkbox' || type == 'radio') this.checked = false; // select elements need to have their 'selectedIndex' property set to -1 // (this works for both single and multiple select elements) else if (tag == 'select') this.selectedIndex = -1; }); };

• How to add star rating to UITableView cell?

  - by RaYell

  I need to display a bunch of UITableViewCell in my iPhone application. Sample look below. I know how I can enable accessory view and image to UITableView cell but the problem is that I need to add a star rating as visible on the screen. There's no fancy logic behind it, it will just be few images that will be either enabled or disabled. I though that I could create a custom UITableViewCell in NIB but how would I use it in cellForRowAtIndexPath method. If it was just one custom cell I'd just provide an outlet for it and hook it with a property and use it there. But since it would be used multiple times I think I'll need to clone it or copy somehow. What is the simpliest way of adding such stuff to UITableViewCell?

• Configuration manager for PHP

  - by Jack

  I am working on code re-factoring of configuration file loading part in PHP. Earlier I was using multiple 'ini' files but now I plan to go for single XML file which will be containing all configuration details of the project. Problem is, if somebody wants configuration file in ini or DB or anything else and not the default one (in this case XML), my code should handle that part. If somebody wants to go for other configuration option like ini, he will have to create ini file similar to my XML configuration file and my configuration manager should take care everything like parsing, storing in cache. For that I need a mechanism lets say proper interface for my configuration data where the underlying data store can be anything( XML, DB, ini etc) also I don't want it to be dependent on these underlying store and anytime in future this should be extensible to other file formats.

• Generating a error code per property in Hibernate validator

  - by Mike Q

  Hi all, I am looking at using hibernate validator for a requirement of mine. I want to validate a bean where properties may have multiple validation checks. e.g. class MyValidationBean { @NotNull @Length( min = 5, max = 10 ) private String myProperty; } But if this property fails validation I want a specific error code to be associated with the ConstraintViolation, regardless of whether it failed because of @Required or @Length, although I would like to preserve the error message. class MyValidationBean { @NotNull @Length( min = 5, max = 10 ) @ErrorCode( "1234" ) private String myProperty; } Something like the above would be good but it doesn't have to be structured exactly like that. I can't see a way to do this with hibernate validator. Is it possible? Thanks.

• JSON encode MySQL results then read using jQuery

  - by silentw

  I have a database table with some rows that I want to fetch using PHP and then encode them using JSON. Currently, my database structure is the following: idcomponente | quantidade After fetching the values in PHP, I want to know how can I encode them using JSON (with multiple rows, using the same names) so I can read them using jQuery.post(). $.post('test.php',{id:id},function(data){ //READ data HERE }); Thanks in advance Edit: So far, I made this: $.post('edit/producomponentes.php',{id:id},function(data){ console.log(data); }); Logs this: [Object { componente="1", quantidade="2"}, Object { componente="3", quantidade="3"}] Now how can I go through each row and fetch their properties? (data.componente, data.quantidade)

• Computationally simple Pseudo-Gaussian Distribution with varying mean and standard deviation?

  - by mstksg

  This picture from wikipedia has a nice example of the sort of functions I'd ideally like to generate http://en.wikipedia.org/wiki/File:Normal_Distribution_PDF.svg Right now I'm using the Irwin-Hall Distribution, which is more or less a Polynomial approximation of the Gaussian distribution...basically, you use uniform random number generator and iterate it x times, and take the average. The more iterations, the more like a Gaussian Distribution it is. It's pretty nice; however I'd like to be able to have one where I can vary the mean. For example, let's say I wanted a number between the range 0 and 10, but around 7. Like, the mean (if I repeated this function multiple times) would turn out to be 7, but the actual range is 0-10. Is there one I should look up, or should I work on doing some fancy maths with standard Gaussian Distributions?

• What do I use when a cron job isn't enough? (php)

  - by mike

  I'm trying to figure out the most efficient way to running a pretty hefty PHP task thousands of times a day. It needs to make an IMAP connection to Gmail, loop over the emails, save this info to the database and save images locally. Running this task every so often using a cron isn't that big of a deal, but I need to run it every minute and I know eventually the crons will start running on top of each other and cause memory issues. What is the next step up when you need to efficiently run a task multiple times a minute? I've been reading about beanstalk & pheanstalk and I'm not entirely sure if that will do what I need. Thoughts???

• Is Stopwatch really broken?

  - by Jakub Šturc

  At MSDN page for Stopwatch class I discovered link to interesting article which makes following statement about Stopwatch: However there are some serious issues: This can be unreliable on a PC with multiple processors. Due to a bug in the BIOS, Start() and Stop() must be executed on the same processor to get a correct result. This is unreliable on processors that do not have a constant clock speed (most processors can reduce the clock speed to conserve energy). This is explained in detail here. I am little confused. I've seen tons of examples of using Stopwatch and nobody mention this drawbacks. How serious is this? Should I avoid using Stopwatch?

• Insert xelements using LINQ Select?

  - by Simon Woods

  I have a source piece of xml into which I want to insert multiple elements which are created dependant upon certain values found in the original xml At present I have a sub which does this for me: <Extension()> Public Sub AddElements(ByVal xml As XElement, ByVal elementList As IEnumerable(Of XElement)) For Each e In elementList xml.Add(e) Next End Sub And this is getting invoked in a routine as follows: Dim myElement = New XElement("NewElements") myElement.AddElements( xml.Descendants("TheElements"). Where(Function(e) e.Attribute("FilterElement") IsNot Nothing). Select(Function(e) New XElement("NewElement", New XAttribute("Text", e.Attribute("FilterElement").Value)))) Is it possible to re-write this using Linq syntax so I don't need to call out to the Sub AddElements but could do it all in-line Many Thx Simon

  I have developed a .Net 3.5 windows forms application. I also want to design a website that has a webservice with multiple Webmethods to query the database on the host machine. I want the webservice to be called ONLY through my winapp and my website! And I don't want any other people to be able to call and use my webservice but only some people who have access to the windows application that I have developed. I need a good security scenario for this! I truly appreciate anyone who can help me because this is my first experience of developing a webservice and I really need it to be as secure as I mentioned!

• Is there a C# open-source search app which scales cheaply?

  - by domspurling

  I need to quickly replace a listings website which has the following characteristics: smallish database (10,000 items, < 1GB) < 10% of the items updated/created/removed daily most common activity is searching the whole dataset, returning 1-1000 items traffic peaks at 1m page impressions per day Scaling strategy for the existing app has been to separate read-only and read/write activity. Multiple slave databases are used for searching and writes are done to a master, which update the slaves using MS SQL replication. Since read activity is more common than write, this has proved to be a cheap way to do database load balancing, without true clustering. I now need to replace the app - are there any C# open-source apps which scale as neatly as this?

• Edit Distance in Python

  - by Alice

  I'm programming a spellcheck program in Python. I have a list of valid words (the dictionary) and I need to output a list of words from this dictionary that have an edit distance of 2 from a given invalid word. I know I need to start by generating a list with an edit distance of one from the invalid word(and then run that again on all the generated words). I have three methods, inserts(...), deletions(...) and changes(...) that should output a list of words with an edit distance of 1, where inserts outputs all valid words with one more letter than the given word, deletions outputs all valid words with one less letter, and changes outputs all valid words with one different letter. I've checked a bunch of places but I can't seem to find an algorithm that describes this process. All the ideas I've come up with involve looping through the dictionary list multiple times, which would be extremely time consuming. If anyone could offer some insight, I'd be extremely grateful. Thanks!

• How do I compute the approximate entropy of a bit string?

  - by dreeves

  Is there a standard way to do this? Googling -- "approximate entropy" bits -- uncovers multiple academic papers but I'd like to just find a chunk of pseudocode defining the approximate entropy for a given bit string of arbitrary length. (In case this is easier said than done and it depends on the application, my application involves 16,320 bits of encrypted data (cyphertext). But encrypted as a puzzle and not meant to be impossible to crack. I thought I'd first check the entropy but couldn't easily find a good definition of such. So it seemed like a question that ought to be on StackOverflow! Ideas for where to begin with de-cyphering 16k random-seeming bits are also welcome...)

• Multi-part gzip file random access (in Java)

  - by toluju

  This may fall in the realm of "not really feasible" or "not really worth the effort" but here goes. I'm trying to randomly access records stored inside a multi-part gzip file. Specifically, the files I'm interested in are compressed Heretrix Arc files. (In case you aren't familiar with multi-part gzip files, the gzip spec allows multiple gzip streams to be concatenated in a single gzip file. They do not share any dictionary information, it is simple binary appending.) I'm thinking it should be possible to do this by seeking to a certain offset within the file, then scan for the gzip magic header bytes (i.e. 0x1f8b, as per the RFC), and attempt to read the gzip stream from the following bytes. The problem with this approach is that those same bytes can appear inside the actual data as well, so seeking for those bytes can lead to an invalid position to start reading a gzip stream from. Is there a better way to handle random access, given that the record offsets aren't known a priori?

• How are SaaS applications organized?

  - by tomekw

  Consider web (MVC, for example Rails) application for multiple clients as a service. How to design this? one application instance per client? (+ one database per client) one instance for all clients (+ one database for all clients) Former one is simple, but... "inefficient". How about the latter? (best practises, design patterns) How to separate client data? For example: worker "A" of client "1" has two documents, worker "B" of client "2" has three documents. How to build model associations to protect other users (and clients) data? I think joining every query with Client model is not a good solution.

• How can it be impossible to "decrypt" an MD5 hash?

  - by Rob

  I was reading a question about MD5, and it made me remember something that boggles me. Very simple question, and I'm sorry if it's not a good one. I just can't understand how you convert something to one thing using some algorithm, and there being no way to convert it back using the algorithm in reverse. So how is this possible? Also, since multiple strings can create the same MD5 hash, due to it being less data than the input string, how would any other hashing system be any better?

• Oracle RightNow CX for Good Customer Experiences

  - by Andreea Vaduva

  Oracle RightNow CX is all about the customer experience, it’s about understanding what drives a good interaction and it’s about delivering a solution which works for our customers and by extension, their customers. One of the early guiding principles of Oracle RightNow was an 8-point strategy to providing good customer experiences. Establish a knowledge foundation Empowering the customer Empower employees Offer multi-channel choice Listen to the customer Design seamless experiences Engage proactively Measure and improve continuously The application suite provides all of the tools necessary to deliver a rewarding, repeatable and measurable relationship between business and customer. The Knowledge Authoring tool provides gap analysis, WYSIWIG editing (and includes HTML rich content for non-developers), multi-level categorisation, permission based publishing and Web self-service publishing. Oracle RightNow Customer Portal, is a complete web application framework that enables businesses to control their own end-user page branding experience, which in turn will allow customers to self-serve. The Contact Centre Experience Designer builds a combination of workspaces, agent scripting and guided assistances into a Desktop Workflow. These present an agent with the tools they need, at the time they need them, providing even the newest and least experienced advisors with consistently accurate and efficient information, whilst guiding them through the complexities of internal business processes. Oracle RightNow provides access points for customers to feedback about specific knowledge articles or about the support site in general. The system will generate ‘incidents’ based on the scoring of the comments submitted. This makes it easy to view and respond to customer feedback. It is vital, more now than ever, not to under-estimate the power of the social web – Facebook, Twitter, YouTube – they have the ability to cause untold amounts of damage to businesses with a single post – witness musician Dave Carroll and his protest song on YouTube, posted in response to poor customer services from an American airline. The first day saw 150,000 views and is currently at 12,011,375. The Times reported that within 4 days of the post, the airline’s stock price fell by 10 percent, which represented a cost to shareholders of $180 million dollars. It is a universally acknowledged fact, that when customers are unhappy, they will not come back, and, generally speaking, it only takes one bad experience to lose a customer. The idea that customer loyalty can be regained by using social media channels was the subject of a 2011 Survey commissioned by RightNow and conducted by Harris Interactive. The survey discovered that 68% of customers who posted a negative review about a holiday on a social networking site received a response from the business. It further found that 33% subsequently posted a positive review and 34% removed the original negative review. Cloud Monitor provides the perfect mechanism for seeing what is being said about a business on public Facebook pages, Twitter or YouTube posts; it allows agents to respond proactively – either by creating an Oracle RightNow incident or by using the same channel as the original post. This leaves step 8 – Measuring and Improving: How does a business know whether it’s doing the right thing? How does it know if its customers are happy? How does it know if its staff are being productive? How does it know if its staff are being effective? Cue Oracle RightNow Analytics – fully integrated across the entire platform – Service, Marketing and Sales – there are in excess of 800 standard reports. If this were not enough, a large proportion of the database has been made available via the administration console, allowing users without any prior database experience to write their own reports, format them and schedule them for e-mail delivery to a distribution list. It handles the complexities of table joins, and allows for the manipulation of data with ease.

• Ruby open-uri open method loses file extension opening images

  I'm using ruby 1.9.2 along with Rails 3.1.4 and Paperclip 2.4.5. My issue is trying to save a paperclip attachment from a URI loses the file extension and saves the file without one resulting in issues with things like fancybox that require an extension. Some example code: uri = "http://featherfiles.aviary.com/2012-06-13/bbe5f0de1/0c5a672b88ea47ecb4631ac173e27430.png" open(uri) #=> #<File:/var/folders/zc/d69gxhzx10x_bvjrkqgyjgxr0000gn/T/open-uri20120613-27204-i6cldv> Because there is no extension on the temp file paperclip is saving the file without one resulting in issues. Has anyone run into this issue? I've seen multiple answers about using paperclip to store images from a URI but none seem to address the same problem we're running
