  • Can I use `UnlockCommercialFeatures` for developing Java applications without a commercial license?

    - by nondescript1
    As of Java 7 Update 40, Oracle is now including Java Mission Control in the JDK. Being always interested in a new profiling tool, I decided to check it out. However, trying to start Flight Recorder against a process, I get the following error, Now I'm getting cold feet about adding the JVM option -XX:+UnlockCommercialFeatures. I would only use this for profiling in development and not in production. From the article linked above, JMC is available under the Oracle Binary Code License for Java. The license allows you to use JMC for free during development and testing, though a different (paid for) licence is required for production use. I'm still leery about this. From Java SE Products, Flight Recorder certainly is a commercial feature; however, I find it very confusing that it's now included in the standard JDK release. Anyone else have a read on this? Clearly nothing here is legally binding and your legal department should be consulted. Reference: Oracle Binary Code License Agreement for the Java SE Platform Products and JavaFX

  • Web API, JavaScript, Chrome &amp; Cross-Origin Resource Sharing

    - by Brian Lanham
    The team spent much of the week working through this issues related to Chrome running on Windows 8 consuming cross-origin resources using Web API.  We thought it was resolved on day 2 but it resurfaced the next day.  We definitely resolved it today though.  I believe I do not fully understand the situation but I am going to explain what I know in an effort to help you avoid and/or resolve a similar issue. References We referenced many sources during our trial-and-error troubleshooting.  These are the links we reference in order of applicability to the solution: Zoiner Tejada JavaScript and other material from -> http://www.devproconnections.com/content1/topic/microsoft-azure-cors-141869/catpath/windows-azure-platform2/page/3 WebDAV Where I learned about “Accept” –>  http://www-jo.se/f.pfleger/cors-and-iis? IT Hit Tells about NOT using ‘*’ –> http://www.webdavsystem.com/ajax/programming/cross_origin_requests Carlos Figueira Sample back-end code (newer) –> http://code.msdn.microsoft.com/windowsdesktop/Implementing-CORS-support-a677ab5d (older version) –> http://code.msdn.microsoft.com/CORS-support-in-ASPNET-Web-01e9980a   Background As a measure of protection, Web designers (W3C) and implementers (Google, Microsoft, Mozilla) made it so that a request, especially a JSON request (but really any URL), sent from one domain to another will only work if the requestee “knows” about the requester and allows requests from it. So, for example, if you write a ASP.NET MVC Web API service and try to consume it from multiple apps, the browsers used may (will?) indicate that you are not allowed by showing an “Access-Control-Allow-Origin” error indicating the requester is not allowed to make requests. Internet Explorer (big surprise) is the odd-hair-colored step-child in this mix. It seems that running locally at least IE allows this for development purposes.  Chrome and Firefox do not.  In fact, Chrome is quite restrictive.  Notice the images below. IE shows data (a tabular view with one row for each day of a week) while Chrome does not (trust me, neither does Firefox).  Further, the Chrome developer console shows an XmlHttpRequest (XHR) error. Screen captures from IE (left) and Chrome (right). Note that Chrome does not display data and the console shows an XHR error. Why does this happen? The Web browser submits these requests and processes the responses and each browser is different. Okay, so, IE is probably the only one that’s truly different.  However, Chrome has a specific process of performing a “pre-flight” check to make sure the service can respond to an “Access-Control-Allow-Origin” or Cross-Origin Resource Sharing (CORS) request.  So basically, the sequence is, if I understand correctly:  1)Page Loads –> 2)JavaScript Request Processed by Browser –> 3)Browsers Prepares to Submit Request –> 4)[Chrome] Browser Submits Pre-Flight Request –> 5)Server Responds with HTTP 200 –> 6)Browser Submits Request –> 7)Server Responds with Data –> 8)Page Shows Data This situation occurs for both GET and POST methods.  Typically, GET methods are called with query string parameters so there is no data posted.  Instead, the requesting domain needs to be permitted to request data but generally nothing more is required.  POSTs on the other hand send form data.  Therefore, more configuration is required (you’ll see the configuration below).  AJAX requests are not friendly with this (POSTs) either because they don’t post in a form. How to fix it. The team went through many iterations of self-hair removal and we think we finally have a working solution.  The trial-and-error approach eventually worked and we referenced many sources for the information.  I indicate those references above.  There are basically three (3) tasks needed to make this work. Assumptions: You are using Visual Studio, Web API, JavaScript, and have Cross-Origin Resource Sharing, and several browsers. 1. Configure the client Joel Cochran centralized our “cors-oriented” JavaScript (from here). There are two calls including one for GET and one for POST function(url, data, callback) {             console.log(data);             $.support.cors = true;             var jqxhr = $.post(url, data, callback, "json")                 .error(function(jqXhHR, status, errorThrown) {                     if ($.browser.msie && window.XDomainRequest) {                         var xdr = new XDomainRequest();                         xdr.open("post", url);                         xdr.onload = function () {                             if (callback) {                                 callback(JSON.parse(this.responseText), 'success');                             }                         };                         xdr.send(data);                     } else {                         console.log(">" + jqXhHR.status);                         alert("corsAjax.post error: " + status + ", " + errorThrown);                     }                 });         }; The GET CORS JavaScript function (credit to Zoiner Tejada) function(url, callback) {             $.support.cors = true;             var jqxhr = $.get(url, null, callback, "json")                 .error(function(jqXhHR, status, errorThrown) {                     if ($.browser.msie && window.XDomainRequest) {                         var xdr = new XDomainRequest();                         xdr.open("get", url);                         xdr.onload = function () {                             if (callback) {                                 callback(JSON.parse(this.responseText), 'success');                             }                         };                         xdr.send();                     } else {                         alert("CORS is not supported in this browser or from this origin.");                     }                 });         }; The POST CORS JavaScript function (credit to Zoiner Tejada) Now you need to call these functions to get and post your data (instead of, say, using $.Ajax). Here is a GET example: corsAjax.get(url, function(data) { if (data !== null && data.length !== undefined) { // do something with data } }); And here is a POST example: corsAjax.post(url, item); Simple…except…you’re not done yet. 2. Change Web API Controllers to Allow CORS There are actually two steps here.  Do you remember above when we mentioned the “pre-flight” check?  Chrome actually asks the server if it is allowed to ask it for cross-origin resource sharing access.  So you need to let the server know it’s okay.  This is a two-part activity.  a) Add the appropriate response header Access-Control-Allow-Origin, and b) permit the API functions to respond to various methods including GET, POST, and OPTIONS.  OPTIONS is the method that Chrome and other browsers use to ask the server if it can ask about permissions.  Here is an example of a Web API controller thus decorated: NOTE: You’ll see a lot of references to using “*” in the header value.  For security reasons, Chrome does NOT recognize this is valid. [HttpHeader("Access-Control-Allow-Origin", "http://localhost:51234")] [HttpHeader("Access-Control-Allow-Credentials", "true")] [HttpHeader("Access-Control-Allow-Methods", "ACCEPT, PROPFIND, PROPPATCH, COPY, MOVE, DELETE, MKCOL, LOCK, UNLOCK, PUT, GETLIB, VERSION-CONTROL, CHECKIN, CHECKOUT, UNCHECKOUT, REPORT, UPDATE, CANCELUPLOAD, HEAD, OPTIONS, GET, POST")] [HttpHeader("Access-Control-Allow-Headers", "Accept, Overwrite, Destination, Content-Type, Depth, User-Agent, X-File-Size, X-Requested-With, If-Modified-Since, X-File-Name, Cache-Control")] [HttpHeader("Access-Control-Max-Age", "3600")] public abstract class BaseApiController : ApiController {     [HttpGet]     [HttpOptions]     public IEnumerable<foo> GetFooItems(int id)     {         return foo.AsEnumerable();     }     [HttpPost]     [HttpOptions]     public void UpdateFooItem(FooItem fooItem)     {         // NOTE: The fooItem object may or may not         // (probably NOT) be set with actual data.         // If not, you need to extract the data from         // the posted form manually.         if (fooItem.Id == 0) // However you check for default...         {             // We use NewtonSoft.Json.             string jsonString = context.Request.Form.GetValues(0)[0].ToString();             Newtonsoft.Json.JsonSerializer js = new Newtonsoft.Json.JsonSerializer();             fooItem = js.Deserialize<FooItem>(new Newtonsoft.Json.JsonTextReader(new System.IO.StringReader(jsonString)));         }         // Update the set fooItem object.     } } Please note a few specific additions here: * The header attributes at the class level are required.  Note all of those methods and headers need to be specified but we find it works this way so we aren’t touching it. * Web API will actually deserialize the posted data into the object parameter of the called method on occasion but so far we don’t know why it does and doesn’t. * [HttpOptions] is, again, required for the pre-flight check. * The “Access-Control-Allow-Origin” response header should NOT NOT NOT contain an ‘*’. 3. Headers and Methods and Such We had most of this code in place but found that Chrome and Firefox still did not render the data.  Interestingly enough, Fiddler showed that the GET calls succeeded and the JSON data is returned properly.  We learned that among the headers set at the class level, we needed to add “ACCEPT”.  Note that I accidentally added it to methods and to headers.  Adding it to methods worked but I don’t know why.  We added it to headers also for good measure. [HttpHeader("Access-Control-Allow-Methods", "ACCEPT, PROPFIND, PROPPA... [HttpHeader("Access-Control-Allow-Headers", "Accept, Overwrite, Destin... Next Steps That should do it.  If it doesn’t let us know.  What to do next?  * Don’t hardcode the allowed domains.  Note that port numbers and other domain name specifics will cause problems and must be specified.  If this changes do you really want to deploy updated software?  Consider Miguel Figueira’s approach in the following link to writing a custom HttpHeaderAttribute class that allows you to specify the domain names and then you can do it dynamically.  There are, of course, other ways to do it dynamically but this is a clean approach. http://code.msdn.microsoft.com/windowsdesktop/Implementing-CORS-support-a677ab5d

  • How can I use iteration to lead targets?

    - by e100
    In my 2D game, I have stationary AI turrets firing constant speed bullets at moving targets. So far I have used a quadratic solver technique to calculate where the turret should aim in advance of the target, which works well (see Algorithm to shoot at a target in a 3d game, Predicting enemy position in order to have an object lead its target). But it occurs to me that an iterative technique might be more realistic (e.g. it should fire even when there is no exact solution), efficient and tunable - for example one could change the number of iterations to improve accuracy. I thought I could calculate the current range and thus an initial (inaccurate) bullet flight time to target, then work out where the target would actually be by that time, then recalculate a more accurate range, then recalculate flight time, etc etc. I think I am missing something obvious to do with the time term, but my aimpoint calculation does not currently converge after the significant initial correction in the first iteration: import math def aimpoint(iters, target_x, target_y, target_vel_x, target_vel_y, bullet_speed): aimpoint_x = target_x aimpoint_y = target_y range = math.sqrt(aimpoint_x**2 + aimpoint_y**2) time_to_target = range / bullet_speed time_delta = time_to_target n = 0 while n <= iters: print "iteration:", n, "target:", "(", aimpoint_x, aimpoint_y, ")", "time_delta:", time_delta aimpoint_x += target_vel_x * time_delta aimpoint_y += target_vel_y * time_delta range = math.sqrt(aimpoint_x**2 + aimpoint_y**2) new_time_to_target = range / bullet_speed time_delta = new_time_to_target - time_to_target n += 1 aimpoint(iters=5, target_x=0, target_y=100, target_vel_x=1, target_vel_y=0, bullet_speed=100)

  • How is software used in critical life-or-death systems tested?

    - by waiwai933
    An airplane, as opposed to, for example, a website, is a system where any failure in certain systems is completely unacceptable, since errors in e.g. flight monitoring can cause the autopilot to malfunction and do a dive. Obviously, this doesn't happen since the brilliant engineers at Boeing and Airbus have checks in the autopilot to make sure it doesn't suddenly decide a dive is a perfectly acceptable and safe maneuver. Or perhaps the computer crashes, and the pilots in the newer fly-by-wire aircraft can no longer actually fly the plane. Of course, there are various safety procedures and redundancies built into these systems to prevent a crash (of both the software and the aircraft). However, on the other hand, it's quite obvious that software isn't perfect—both open source and closed source software do crash regularly, and only the simplest "Hello World" program doesn't fail. How can the engineers who design the software systems in the aeronautic, medical, and other life-or-death industries manage to test their software so that it doesn't fail (and if it does fail, at least fail gracefully)? I'm desperately hoping that you're not all going to go: "Oh, I work for Boeing/Airbus/(some other company) and it's not! Have fun on your next flight/hospital visit."

  • Can't store array in json field in postgresql (rails) can't cast Array to json

    - by Drew H
    This is the error I'm getting when I run db:migrate rake aborted! can't cast Array to json This is my table class CreateTrips < ActiveRecord::Migration def change create_table :trips do |t| t.json :flights t.timestamps end end end This is in my seeds.rb file flights = [{ depart_time_hour: 600, arrive_time_hour: 700, passengers: [ { user_id: 1, request: true } ] }] trip = Trip.create( { name: 'Flight', flights: flights.to_json } ) For some reason I can't do this. If I do this. trip = Trip.create( { name: 'Flight', flights: { flights: flights.to_json } } ) It works. I don't want this though because now I have to access the json array with trip.flights.flights. Not the behavior I'm wanting.

  • Customised email alerts through MailChimp API

    - by user1293351
    I am building a site that runs an automated process every 30 minutes to match up new flights with their respective user. Once this process is completed I want to email the flight details out to the respective user. However the flight info will be different for every single user with their being 0-300+ potential emails. Is this something that the MailChimp API will allow or do? I found this page http://apidocs.mailchimp.com/api/how-to/transactional-campaigns.php which I am not sure if this effects me. Is the STS more suited to this? http://apidocs.mailchimp.com/sts/1.0/ Thanks Alex

  • Annotations: methods vs variables

    - by Zenzen
    I was always sure (don't know why) that it's better to add annotations to variables, but while browsing the Hibernate doc http://docs.jboss.org/hibernate/stable/annotations/reference/en/html_single/#entity-hibspec-collection I noticed they tend to annotate the methods. So should I put my annotations before methods, like this: @Entity public class Flight implements Serializable { private long id; @Id @GeneratedValue public long getId() { return id; } public void setId(long id) { this.id = id; } } Or is it better to do it like this: @Entity public class Flight implements Serializable { @Id @GeneratedValue private long id; public long getId() { return id; } public void setId(long id) { this.id = id; } } Or maybe there's no difference?

  • how to save state of dynamically created editTexts

    - by user922531
    I'm stuck at how to save the state of my EditTexts on screen orientation. Currently if text is inputted into the EditTexts and the screen is orientated, the fields are wiped (as expected). I am already calling onSaveInstanceState and saving a String, but I have no clue on how to save the EditTexts which are created in code and then retrieve them and add them to the EditTexts when redrawing the activity. Snippet of my code: My main activity is as follows: public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // get the multidim array b = getIntent().getBundleExtra("obj"); m = (Methods) b.getSerializable("Methods"); // method to draw the layout InitialiseUI(); // Restore UI state from the savedInstanceState. if (savedInstanceState != null) { String strValue = savedInstanceState.getString("light"); if (strValue != null) { FLight = strValue; } } try { mCamera = Camera.open(); if (FLight.equals("true")) { flashLight(); } } catch (Exception e) { Log.d(TAG, "Thrown exception onCreate() camera: " + e); } } // end onCreate /** Called when the back button is pressed. */ @Override public void onResume() { super.onResume(); try { mCamera = Camera.open(); if (FLight.equals("true")) { flashLight(); } } catch (Exception e) { Log.d(TAG, "Thrown exception onCreate() camera: " + e); } } // end onCreate /** saves data before leaving the screen */ @Override protected void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); outState.putString("light", FLight); } /** called when exiting / leaving the screen */ @Override protected void onPause() { super.onPause(); Log.d(TAG, "onPause()"); if (mCamera != null) { mCamera.stopPreview(); mCamera.release(); mCamera = null; } } /* * set up the UI elements - add click listeners to buttons used in * onCreate() and onConfigurationChanged() * * Set the editTexts fields to show the previous readings as Hints */ public void InitialiseUI() { Log.d(TAG, "Start of InitialiseUI, Main activity"); // get a reference to the TableLayout final TableLayout myTLreads = (TableLayout) findViewById(R.id.myTLreads); // Create arrays to hold the TVs and ETs final TextView[] myTextViews = new TextView[m.getNoRows()]; // create an empty array; final EditText[] myEditTexts = new EditText[m.getNoRows()]; // create an empty array; for(int i =0; i<=m.getNoRows()-1;i++ ){ TableRow tr=new TableRow(this); tr.setLayoutParams(new LayoutParams( LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT)); // create a new textview / editText final TextView rowTextView = new TextView(this); final EditText rowEditText = new EditText(this); // setWidth is needed otherwise my landscape layout is OFF rowEditText.setWidth(400); // this stops the keyboard taking up the whole screen in landscape layout rowEditText.setImeOptions(EditorInfo.IME_FLAG_NO_EXTRACT_UI); // add some padding to the right of the TV rowTextView.setPadding(0,0,10,0); // set colors to white rowTextView.setTextColor(Color.parseColor("#FFFFFF")); rowEditText.setTextColor(Color.parseColor("#FFFFFF")); // if readings already sent today set color to yellow if(m.getTransmit(i+1)==false){ rowEditText.setEnabled(false); rowEditText.setHintTextColor(Color.parseColor("#FFFF00")); } // set the text of the TV to the meter name rowTextView.setText(m.getMeterName(i+1)); // set the hint of the ET to the last submitted reading rowEditText.setHint(m.getLastReadString(i+1)); // add the textview to the linearlayout rowEditText.setInputType(InputType.TYPE_CLASS_PHONE);//InputType.TYPE_NUMBER_FLAG_DECIMAL); tr.addView(rowTextView); tr.addView(rowEditText); myTLreads.addView(tr); // add a reference to the textView myTextViews[i] = rowTextView; myEditTexts[i] = rowEditText; } final Button submit = (Button) findViewById(R.id.submitReadings); // add a click listener to the button try { submit.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Log.d(TAG, "Submit button clicked, Main activity"); preSubmitCheck(m.getAccNo(), m.getPostCode(), myEditTexts); // method to do HTML getting and sending } }); } catch (Exception e) { Log.d(TAG, "Exceptions (submit button)" + e.toString()); } }// end of InitialiseUI I don't need to do anything with these values until a button is clicked. Would it be easier if they were a ListView, i'm guessing I would still have the problem of saving them and retrieving them on rotation. If it helps I have an object m which is a string[][] I could temporarily somehow store them in

  • JRockit R28/JRockit Mission Control 4.0 is out!

    - by Marcus Hirt
    The next major release of JRockit is finally out! Here are some highlights: Includes the all new JRockit Flight Recorder – supersedes the old JRockit Runtime Analyser. The new flight recorder is inspired by the “black box” in airplanes. It uses a highly efficient recording engine and thread local buffers to capture data about the runtime and the application running in the JVM. It can be configured to always be on, so that whenever anything “interesting” happens, data can be dumped for some time back. Think of it as your own personal profiling time machine. Automatic shortest path calculation in Memleak – no longer any need for running around in circles when trying to find your way back to a thread root from an instance. Memleak can now show class loader related information and split graphs on a per class loader basis. More easily configured JMX agent – default port for both RMI Registry and RMI Server can be configured, and is by default the same, allowing easier configuration of firewalls. Up to 64 GB (was 4GB) compressed references. Per thread allocation profiling in the Management Console. Native Memory Tracking – it is now possible to track native memory allocations with very high resolution. The information can either be accessed using JRCMD, or the dedicated Native Memory Tracking experimental plug-in for the Management Console (alas only available for the upcoming 4.0.1 release). JRockit can now produce heap dumps in HPROF format. Cooperative suspension – JRockit is no longer using system signals for stopping threads, which could lead to hangs if signals were lost or blocked (for example bad NFS shares). Now threads check periodically to see if they are suspended. VPAT/Section 508 compliant JRMC – greatly improved keyboard navigation and screen reader support. See New and Noteworthy for more information. JRockit Mission Control 4.0.0 can be downloaded from here: http://www.oracle.com/technology/software/products/jrockit/index.html <shameless ad> There is even a book to go with JRMC 4.0.0/JRockit R28! http://www.packtpub.com/oracle-jrockit-the-definitive-guide/book/ </shameless ad>

  • Up in the Air: Team Oracle Play-by-Play

    - by Aaron Lazenby
    Yesterday, I had the amazing opportunity to fly along with Sean D. Tucker and Team Oracle. Leaving from the San Carols airport, we did a 30 minute flight over the Pacific just south of the coastal town of Half Moon Bay. In that half hour, I rode through a massive 4G loop, survived a crushing hammerhead, and took control of the plane to perform a basic wing over (you can learn what the heck I'm talking about by visiting this website). I have lots of great video, but it's going to take me some time to make sense of it. For now, here's my Twitter-based play-by-play of yesterday's events. Many thanks to Sean D. Tucker and the whole crew (Ben and Ian, especially) for this great opportunity to fly with Team Oracle.Live tweets from @OracleProfitI will be spending the afternoon in a stunt plane, upside down above the San Francisco bay. http://bit.ly/cwkrkIAt the San Carlos airport. More than slightly freaked out. Shaking hands diminish texting ability. Slightly reassuring. http://yfrog.com/1qt61nj There go the doors to the photo plane... #teamoracle http://yfrog.com/58ywljSean D Tucker assures me: "The sky is a great place to be." Helpful, but I'm still nervous. #teamoracle"You get a parachute. He gets a harness." How was this decision made? #teamoracleThe plane with @radu43 has returned. I'm up next...Couldn't help myself...drank a soda before flying. Mistake? We'll see... #teamoracleAdvice of the day "If you pull with two hands, you improve the chances of the chute deploying on the first try." Lovely. #teamoracleI feel so strange. But I flew a high performance airplane. And did an aerobatics move. Wild. #teamoracle"Flying ten feet off he ground, upside-down at 250 miles per hour isn't exciting to me." Sean D. Tucker #teamoracle"What is exciting to me is flying that perfect pattern, just like I imagined it in my head." Sean D. Tucker #teamoracle"You're going to sleep well tonight. You just carried four times your body weight." #teamoracle #gforce Just watched the #teamoracle plane take off for its flight home. I'm waiting for Caltrain. #undignifiedanticlimaxEnough with the #teamoracle. Check http://blogs.oracle.com/profit for the video. Coming soon!

  • Where can I find luxury goods advertisements for my website?

    - by Nazariy

So I'm curious is there any centralised resources for luxury goods and services?

  • Six Unusual Blogs I Like

    - by Bill Graziano
    I subscribe to and read over 100 SQL Server blogs every day.  I link to posts that I think are interesting.  I also read a fair number of non-SQL Server blogs.  Here are a few that I think are interesting. danah boyd. She is a researcher with Microsoft and writes about privacy, social media and teenagers.  I discovered her blog while looking for strategies to keep my personal and professional life separate.  (I haven’t found a good solution to that yet.)  Her stories of how teenagers use Facebook and other social media tools are fascinating. Clayton’s Web Snacks.  Steve Clayton works at Microsoft and has a variety of blogs out there.  This one focuses on … hmmm.  His latest posts are on graffiti, infographics, paper tweets, cartoons and slow motion videos.  It’s mostly visual and you never really know what you’ll get.  It’s always interesting though and I like what he posts.  It’s good creative stuff. Seth Godin.  Seth writes about Marketing.  I read him for motivation to get off my butt and get things done.  He’s a great motivator who encourages you to think big.  And do something! Ask the Pilot.  Patrick Smith is a commercial airline pilot writing about the airline industry.  He’s a great debunker of myths (no they don’t reduce oxygen in the cabin to keep you docile).  My favorite topics include the TSA, flying myths, airport reviews and flight delays. My old favorite flight blog used to be enplaned.  No one knew who wrote it.  It focused on the economics of the airline industry.  It was fascinating stuff.  One day it was gone.  The entire blog was deleted.  Someone tracked down some partial archives and put them online. The Agent’s Journal.  Jack Bechta is an NFL agent.  He writes about the business side of the NFL, the draft and free agency.  Lately he’s been writing about the potential lockout.  He has a distinct lack of hype which I find very refreshing.  xkcd.  I call this the comic for smart people.  A little math, some IT and internet privacy thrown in all make an unusual comic. Funny and intelligent.

  • What is a good way to test demand for a new game platform?

    - by user15256
    I'm working on a game platform that turns your iPhone, android or iPad into a steering wheel, for racing games (like need for speed and dirt 3) and flight simulators for example. I'd love to figure out smart ways to figure out whether gamers would like something like this. I originally asked this question over on the gaming SE and it was for getflypad.com. A lot of the tech is built and most of it is doable - the question here is how to test demand and know whether gamers actually want this.

  • Understanding When Social Interactions Should Be Resolved in Another Channel

    - by Christina McKeon
    Guest Blogger: Aphrodite Brinsmead, Senior Analyst at Ovum Agents need to respond to customers’ social comments and questions quickly and in the right tone. But more importantly, they need to offer resolutions. Customers care most about how long it takes to find information rather than which channel they are using. They choose to use social media because they are comfortable with the channel and it offers a convenient way to communicate. Ideally agents will resolve questions within social media, but they need guidance as to how and when to escalate interactions to a more private channel. First, businesses should assess the way in which customers are using social media to communicate with them and categorize posts into groups: complaints, feedback, technical queries or more general support questions. They should then consider the types of interactions that can easily be handled within social media and those that need to be followed up in another channel. This will be very dependent on the industry. Examples of queries that can be resolved in social media include Shipping pricing and timeframes Outage updates and resolution plans Flight status information Product stock check Technical support videos or forum posts Availability of facilities Both customers and agents need to be educated about the types of questions they can expect to resolve within social media. As the channel matures as a customer service tool, it needs to have value other than just as a forum for complaints. Social customer service agents need the power to start a web chat or phone call Any questions where customers need to divulge personal details in order to get a resolution will need to be addressed in a private channel: a private social message, web chat, email or phone call. Customers should never disclose their date of birth, social security, credit card number, or healthcare records in a public forum. Flight issues, changes to a booking, billing queries or account updates will all need to be completed via a private interaction. Agents responding to questions on social media need the ability to start a web chat or phone call with the customer. The customer doesn’t want to have to repeat their question and the agent should be empowered to connect customer records and access account or billing information. These agents will need to be trained across different channels and should be able to view all customer communications in one application. They also need to follow up questions that began on a public forum in the initial channel to make it clear that the issue was addressed. In order to make this possible, social media needs to be integrated as part of a broader customer service strategy. Irrespective of how many channels are used to complete an interaction, businesses should prioritize customer satisfaction and issue resolution. They need a clear strategy and trained agents that can handle and respond to social interactions. Follow me on Twitter @diteb.

  • SEO - How to Optimise For Long-Tail Queries

    There is a great deal of value in the long-tail of search. The long-tail is basically a query that is over three or four keywords long. Good examples of long-tail queries include "cheap flights to Japan May" or "buy back doors UK." Both of these terms exhibit a great deal of user intent - this means the users behind both terms are very far down the buying cycle and are looking for a website on which they can transact and buy a flight to Japan or purchase a back door.
