  • higher cpu usage in ubuntu 12.04 than windows 7

    - by Medya
    Hi I have a Intel Core i5 with 6GB of Ram using ubuntu 12.04 64bit. I noticed that whenever I run chrome which is the faster browser for me in linux) when I watch youtube, the CPU usage for Chrome is at least 13% and sometimes even 30% . but in Windows 7 same thing (youtube on chrome) rarely uses more than 6% of my CPU usage. I also notice my laptop is so hot in ubuntu 12.04 and the fan is working all the time, while in windows the laptop is so silent and the fan doesnt make much noise all the time and not as warm as in linux. is it like that for every one or is it just me?

  • How to become a solid python web developer [closed]

    - by Estarius
    Possible Duplicate: How do I learn Python from zero to web development? I have started Python recently with the goal to become a solid developer to make a web application eventually. However, as time goes by I am wondering if I am being optimal about how I will achieve my goal. I would compare it to a game for example, to be better you must spend time playing and trying new things... However, if you just log in and sit in the lobby chatting you are most likely not progressing. So far, this is my plan (feel free to comment or judge it): Review basic programmation concepts Start coding slowly in Python Once comfortable in Python, learn about web development in Python Learn about those things we heard about: SQLAlchemy, MVC, TDD, Git, Agile (Group project) To achieve these things, I started the Learn python the hard way exercises, which I am doing at the rate of 5 per days. I also started to read Think Python at the same time and planning to move on with Dive into python. As far as my research goes, these documentations along with Python documentation is usually what is the most recommended to learn Python. I consider this to get my point 1 and 2 done. While learning Python is really great, my goal remains to do quality web development. I know there are books about Django etc. however I would like to become comfortable with any Python web development. This means without Framework and with Framework... Any framework, then be able to choose the one which best fits our needs. For this I would like to know if some people have suggestions. Should I just get a book on Django and it should apply to everything ? What would be the best method to go from Python to Web Python and not end up creating crappy code which would turn into nightmares for other programmers ? Then finally, those "things we hear about". While I understand what they all do basically, I am fairly sure that like everything, there are good and wrong ways of making use of them. Should I go through at least a whole book on each before starting to use them or keep it at their respective online documentation ? Are there some kind of documentation which links their use to Python ? Also, from looking at Django and Pyramid they seems to use something else than MVC, while the Django model looks similar, the Pyramid one seems to cut a whole part of it... Is learning MVC still worth it ? Sorry for the wall of text, Thanks in advance !

  • How to set wifi driver settings to prefer 5 GHz channel above 2.4 GHz

    - by Wouter
    Currently I'm in a new building of my university. In this building my wifi often breaks down and then restores connection again. This is really irritating since it happens a lot. Now as a coincidence there were some tech guys running around here and where asking everyone if the wifi was doing fine. I told them that my wifi tears down all the time and then reconnects. They figured out that my wifi is switching all the time between the 2.4 GHz channel and 5 GHz channel. They asked me if I could acces the driver settings of my wireless card. Unfortunately I don't know how to do this is in either Linux or Windows. And unfortunately again they only knew the windows solution xD. So I hope somebody can tell me how I tell my wifi that it should stay on the 5 GHz network and not disconnect and switch to the 2.4 GHz channel?

  • Recover that Photo, Picture or File You Deleted Accidentally

    - by The Geek
    Have you ever accidentally deleted a photo on your camera, computer, USB drive, or anywhere else? What you might not know is that you can usually restore those pictures—even from your camera’s memory stick. Windows tries to prevent you from making a big mistake by providing the Recycle Bin, where deleted files hang around for a while—but unfortunately it doesn’t work for external USB drives, USB flash drives, memory sticks, or mapped drives. The great news is that this technique also works if you accidentally deleted the photo… from the camera itself. That’s what happened to me, and prompted writing this article. Restore that File or Photo using Recuva The first piece of software that you’ll want to try is called Recuva, and it’s extremely easy to use—just make sure when you are installing it, that you don’t accidentally install that stupid Yahoo! toolbar that nobody wants. Now that you’ve installed the software, and avoided an awful toolbar installation, launch the Recuva wizard and let’s start through the process of recovering those pictures you shouldn’t have deleted. The first step on the wizard page will let you tell Recuva to only search for a specific type of file, which can save a lot of time while searching, and make it easier to find what you are looking for. Next you’ll need to specify where the file was, which will obviously be up to wherever you deleted it from. Since I deleted mine from my camera’s SD card, that’s where I’m looking for it. The next page will ask you whether you want to do a Deep Scan. My recommendation is to not select this for the first scan, because usually the quick scan can find it. You can always go back and run a deep scan a second time. And now, you’ll see all of the pictures deleted from your drive, memory stick, SD card, or wherever you searched. Looks like what happened in Vegas didn’t stay in Vegas after all… If there are a really large number of results, and you know exactly when the file was created or modified, you can switch to the advanced view, where you can sort by the last modified time. This can help speed up the process quite a bit, so you don’t have to look through quite as many files. At this point, you can right-click on any filename, and choose to Recover it, and then save the files elsewhere on your drive. Awesome! Restore that File or Photo using DiskDigger If you don’t have any luck with Recuva, you can always try out DiskDigger, another excellent piece of software. I’ve tested both of these applications very thoroughly, and found that neither of them will always find the same files, so it’s best to have both of them in your toolkit. Note that DiskDigger doesn’t require installation, making it a really great tool to throw on your PC repair Flash drive. Start off by choosing the drive you want to recover from…   Now you can choose whether to do a deep scan, or a really deep scan. Just like with Recuva, you’ll probably want to select the first one first. I’ve also had much better luck with the regular scan, rather than the “dig deeper” one. If you do choose the “dig deeper” one, you’ll be able to select exactly which types of files you are looking for, though again, you should use the regular scan first. Once you’ve come up with the results, you can click on the items on the left-hand side, and see a preview on the right.  You can select one or more files, and choose to restore them. It’s pretty simple! Download DiskDigger from dmitrybrant.com Download Recuva from piriform.com Good luck recovering your deleted files! And keep in mind, DiskDigger is a totally free donationware software from a single, helpful guy… so if his software helps you recover a photo you never thought you’d see again, you might want to think about throwing him a dollar or two.

  • Java 7 update 6 installation fails on Windows 7 when Chrome is default browser

    - by ali1234
    I am configuring a brand new Lenovo U410 system with Windows 7 Home Premium for a user. I received the system direct from the shop. As part of the configuration I installed Java using the online installer. This worked correctly. Later, due to a mistake I made, I needed to restore the system to factory default. The factory default FORMATS C:\ and puts back (supposedly) the exact factory configuration. However, after doing this, I was no longer able to install Java successfully using the same method I used before. Now, whenever I attempt to use the online Java installer, the following happens. First of all, a window always appears "Welcome to Java", "Downloading Java Installer...". After short time this window disappears and then one of three things happens: The very first time I do this after doing a factory reset, I get a Windows error report, which contains this information: Application Name: JavaSetup7u5.exe Application Version: 7.0.50.6 Application Timestamp: 4feacd84 Fault Module Name: JavaIC.dll Fault Module Version: 9.9.9.9 Fault Module Timestamp: 4f2343d6 Exception Offset: 000052cb Exception Code: c0000417 Exception Data: 00000000 OS Version: 6.1.7600.2.0.0.768.3 Locale ID: 1033 Additional Information 1: 773c Additional Information 2: 773cd78cf06816f8246f359fa270f3bb Additional Information 3: f51a Additional Information 4: f51aaea7d22f36fa9e3a626b5a5cd1c3 2. Subsequent runs produce either this error message: "Error: Java(TM) installer - Downloaded file C:\Users\\AppData\Local\Temp\fx-runtime.exe is corrupt." or Nothing happens at all. I Believe this is a red herring. Running the installer again causes a different error because the files were downloaded and the installer crashed before it could clean up. This isn't the actual problem, as when this happens the installer deletes the downloaded files, and then when you run it for the third time, it downloads everything again and does the javaic.dll crash. I suspect the downloader is appending to the existing files or something, causing the corruption. I have tried all of the above as Administrator and as a normal user. I have tried reseting the system to factory defaults several times. I have tried downloading with Chrome and Internet Explorer 9. I have tried uninstalling all anti-virus software and disabling the windows firewall entirely. The only thing which makes a difference is running the installer in Windows XP compatibility mode, which allows the installation to complete. I know I can workaround this error by using the offline installer so please don't post that as an answer. I am looking for an explanation of the root cause. Additionally, if I use the offline installer, the updater does not work. The updater also does not work if I install in XP mode. The updater fails because it works by just downloading the newest online setup and running it. Also remember that the installers are digitally signed. The signitures verify correctly so there is no way in hell that this is caused by corrupted downloads. Some theories I have: The Java setup files on java.com actually changed in between the first successful install and my later attempts. Seems unlikely as none of the version numbers have changed. However, I have seen a couple of reports of this error which showed up in the past 24 hours. This looks like the most likely explanation right now: http://www.oracle.com/us/corporate/press/1735645 - Oracle released 7 update 6 two days ago. Careful inspection of the installers reveal that they are in fact attempting to download .6, not .5 as the download page claims. Not actually correct. Only the update tool tries to install 7u6. The online installer still tries 7u5. However, 7u6 being released two days ago is too much of a coincidence to ignore. Update: The 7u6 online installer is available from Oracle technetwork. It crashes in exactly the same way. The factory reset software uses GMT-8 and I am on GMT-1. As a result, after factory reset, any software which cares to check would think that the system was restored 7 hours in the future, due to Window's awful policy of storing local time in the system clock. This could be confusing a certificate check or similar. Update: I discovered that this does cause Windows Update to fail. The workaround, setting the clock back before starting factory reset, does not enable Java to install correctly. The factory reset image isn't really the same as what is installed in the main partition when you buy the system. Naughty Lenovo. The installer appears to crash while installing or displaying something to do with the Ask.com toolbar. That seems to be what javaic.dll does. Microsoft Tuesday was the 14th. Some update in that could be causing this. However, I'm factory reseting the machine every time, so unless the patches get slipstreamed into the recovery image, or there is some mechanism by which they get silently installed even if updates are disabled, then I don't see how this can be the cause. Major breakthrough: The default browser on Lenovo systems is Google Chrome. I noticed that the JavaIC.dll "sponsor check" actually does a check on your default browser in order to decide which sponsor ad to display. Normally that would get you the Ask toolbar on IE9. But that toolbar doesn't work on Chrome, and so the installer tries to display a different ad. The different ad is what causes the crash. Changing the default browser to IE9 allows the installer to run correctly. So this looks like a genuine bug in the sponsor ad code in the installer, caused by a combination of Google Chrome default browser and not being in the US. (Installer also checks your location using IP geolocation service and displays different ads based on that.)

  • TechEd 2012: Day 3 &ndash; Morning TFS

    - by Tim Murphy
    My morning sessions for day three were dominated by Team Foundation Server.  This has been a hot topic for our clients lately, so this topic really stuck a chord. The speaker for the first session was from Boeing.  It was nice to hear how how a company mixes both agile and waterfall project management.   The approaches that he presented were very pragmatic.  For their needs reporting is the crucial part of their decision to use TFS.  This was interesting since this is probably the last aspect that most shops would think about. The challenge of getting users to adopt TFS was brought up by the audience.  As with the other discussion point he took a very level headed stance.  The approach he was prescribing was to eat the elephant a bite at a time instead of all at once.  If you try to convert you entire shop at once the culture shock will most likely kill the effort. Another key point he reminded us of is that you need to make sure that standards and compliance are taken into account when you setup TFS.  If you don’t implement a tool and processes around it that comply with the standards bodies that govern your business you are in for a world of hurt. Ultimately the reason they chose TFS was because it was the first tool that incorporated all the ALM features that they needed. Reduced licensing cost because of all the different tools they would need to buy to complete the same tasks.  They got to this point by doing an industry evaluation.  Although TFS came out on top he said that it still has a big gap is in the Java area.  Of course in this market there are vendors helping to close that gap. The second session was on how continuous feedback in agile is a new focus in VS2012.  The problems they intended to address included cycle time and average time to repair, root cause analysis. The speakers fired features at us as if they were firing a machine gun.  I will just say that I am looking forward to digging into the product after seeing this presentation.  Beyond that I will simply list some of the key features that caught my attention. Feature – Ability to link documents into tasks as artifacts Web access portal PowerPoint storyboards Exploratory testing Request feedback (allows users to record notes, screen shots and video/audio) See you after the second half. del.icio.us Tags: TechEd,TechEd 2012,TFS,Team Foundation Server

  • C#: Why Decorate When You Can Intercept

    - by James Michael Hare
    We've all heard of the old Decorator Design Pattern (here) or used it at one time or another either directly or indirectly.  A decorator is a class that wraps a given abstract class or interface and presents the same (or a superset) public interface but "decorated" with additional functionality.   As a really simplistic example, consider the System.IO.BufferedStream, it itself is a descendent of System.IO.Stream and wraps the given stream with buffering logic while still presenting System.IO.Stream's public interface:   1: Stream buffStream = new BufferedStream(rawStream); Now, let's take a look at a custom-code example.  Let's say that we have a class in our data access layer that retrieves a list of products from a database:  1: // a class that handles our CRUD operations for products 2: public class ProductDao 3: { 4: ... 5:  6: // a method that would retrieve all available products 7: public IEnumerable<Product> GetAvailableProducts() 8: { 9: var results = new List<Product>(); 10:  11: // must create the connection 12: using (var con = _factory.CreateConnection()) 13: { 14: con.ConnectionString = _productsConnectionString; 15: con.Open(); 16:  17: // create the command 18: using (var cmd = _factory.CreateCommand()) 19: { 20: cmd.Connection = con; 21: cmd.CommandText = _getAllProductsStoredProc; 22: cmd.CommandType = CommandType.StoredProcedure; 23:  24: // get a reader and pass back all results 25: using (var reader = cmd.ExecuteReader()) 26: { 27: while(reader.Read()) 28: { 29: results.Add(new Product 30: { 31: Name = reader["product_name"].ToString(), 32: ... 33: }); 34: } 35: } 36: } 37: }            38:  39: return results; 40: } 41: } Yes, you could use EF or any myriad other choices for this sort of thing, but the germaine point is that you have some operation that takes a non-trivial amount of time.  What if, during the production day I notice that my application is performing slowly and I want to see how much of that slowness is in the query versus my code.  Well, I could easily wrap the logic block in a System.Diagnostics.Stopwatch and log the results to log4net or other logging flavor of choice: 1:     // a class that handles our CRUD operations for products 2:     public class ProductDao 3:     { 4:         private static readonly ILog _log = LogManager.GetLogger(typeof(ProductDao)); 5:         ... 6:         7:         // a method that would retrieve all available products 8:         public IEnumerable<Product> GetAvailableProducts() 9:         { 10:             var results = new List<Product>(); 11:             var timer = Stopwatch.StartNew(); 12:             13:             // must create the connection 14:             using (var con = _factory.CreateConnection()) 15:             { 16:                 con.ConnectionString = _productsConnectionString; 17:                 18:                 // and all that other DB code... 19:                 ... 20:             } 21:             22:             timer.Stop(); 23:             24:             if (timer.ElapsedMilliseconds > 5000) 25:             { 26:                 _log.WarnFormat("Long query in GetAvailableProducts() took {0} ms", 27:                     timer.ElapsedMillseconds); 28:             } 29:             30:             return results; 31:         } 32:     } In my eye, this is very ugly.  It violates Single Responsibility Principle (SRP), which says that a class should only ever have one responsibility, where responsibility is often defined as a reason to change.  This class (and in particular this method) has two reasons to change: If the method of retrieving products changes. If the method of logging changes. Well, we could “simplify” this using the Decorator Design Pattern (here).  If we followed the pattern to the letter, we'd need to create a base decorator that implements the DAOs public interface and forwards to the wrapped instance.  So let's assume we break out the ProductDAO interface into IProductDAO using your refactoring tool of choice (Resharper is great for this). Now, ProductDao will implement IProductDao and get rid of all logging logic: 1:     public class ProductDao : IProductDao 2:     { 3:         // this reverts back to original version except for the interface added 4:     } 5:  And we create the base Decorator that also implements the interface and forwards all calls: 1:     public class ProductDaoDecorator : IProductDao 2:     { 3:         private readonly IProductDao _wrappedDao; 4:         5:         // constructor takes the dao to wrap 6:         public ProductDaoDecorator(IProductDao wrappedDao) 7:         { 8:             _wrappedDao = wrappedDao; 9:         } 10:         11:         ... 12:         13:         // and then all methods just forward their calls 14:         public IEnumerable<Product> GetAvailableProducts() 15:         { 16:             return _wrappedDao.GetAvailableProducts(); 17:         } 18:     } This defines our base decorator, then we can create decorators that add items of interest, and for any methods we don't decorate, we'll get the default behavior which just forwards the call to the wrapper in the base decorator: 1:     public class TimedThresholdProductDaoDecorator : ProductDaoDecorator 2:     { 3:         private static readonly ILog _log = LogManager.GetLogger(typeof(TimedThresholdProductDaoDecorator)); 4:         5:         public TimedThresholdProductDaoDecorator(IProductDao wrappedDao) : 6:             base(wrappedDao) 7:         { 8:         } 9:         10:         ... 11:         12:         public IEnumerable<Product> GetAvailableProducts() 13:         { 14:             var timer = Stopwatch.StartNew(); 15:             16:             var results = _wrapped.GetAvailableProducts(); 17:             18:             timer.Stop(); 19:             20:             if (timer.ElapsedMilliseconds > 5000) 21:             { 22:                 _log.WarnFormat("Long query in GetAvailableProducts() took {0} ms", 23:                     timer.ElapsedMillseconds); 24:             } 25:             26:             return results; 27:         } 28:     } Well, it's a bit better.  Now the logging is in its own class, and the database logic is in its own class.  But we've essentially multiplied the number of classes.  We now have 3 classes and one interface!  Now if you want to do that same logging decorating on all your DAOs, imagine the code bloat!  Sure, you can simplify and avoid creating the base decorator, or chuck it all and just inherit directly.  But regardless all of these have the problem of tying the logging logic into the code itself. Enter the Interceptors.  Things like this to me are a perfect example of when it's good to write an Interceptor using your class library of choice.  Sure, you could design your own perfectly generic decorator with delegates and all that, but personally I'm a big fan of Castle's Dynamic Proxy (here) which is actually used by many projects including Moq. What DynamicProxy allows you to do is intercept calls into any object by wrapping it with a proxy on the fly that intercepts the method and allows you to add functionality.  Essentially, the code would now look like this using DynamicProxy: 1: // Note: I like hiding DynamicProxy behind the scenes so users 2: // don't have to explicitly add reference to Castle's libraries. 3: public static class TimeThresholdInterceptor 4: { 5: // Our logging handle 6: private static readonly ILog _log = LogManager.GetLogger(typeof(TimeThresholdInterceptor)); 7:  8: // Handle to Castle's proxy generator 9: private static readonly ProxyGenerator _generator = new ProxyGenerator(); 10:  11: // generic form for those who prefer it 12: public static object Create<TInterface>(object target, TimeSpan threshold) 13: { 14: return Create(typeof(TInterface), target, threshold); 15: } 16:  17: // Form that uses type instead 18: public static object Create(Type interfaceType, object target, TimeSpan threshold) 19: { 20: return _generator.CreateInterfaceProxyWithTarget(interfaceType, target, 21: new TimedThreshold(threshold, level)); 22: } 23:  24: // The interceptor that is created to intercept the interface calls. 25: // Hidden as a private inner class so not exposing Castle libraries. 26: private class TimedThreshold : IInterceptor 27: { 28: // The threshold as a positive timespan that triggers a log message. 29: private readonly TimeSpan _threshold; 30:  31: // interceptor constructor 32: public TimedThreshold(TimeSpan threshold) 33: { 34: _threshold = threshold; 35: } 36:  37: // Intercept functor for each method invokation 38: public void Intercept(IInvocation invocation) 39: { 40: // time the method invocation 41: var timer = Stopwatch.StartNew(); 42:  43: // the Castle magic that tells the method to go ahead 44: invocation.Proceed(); 45:  46: timer.Stop(); 47:  48: // check if threshold is exceeded 49: if (timer.Elapsed > _threshold) 50: { 51: _log.WarnFormat("Long execution in {0} took {1} ms", 52: invocation.Method.Name, 53: timer.ElapsedMillseconds); 54: } 55: } 56: } 57: } Yes, it's a bit longer, but notice that: This class ONLY deals with logging long method calls, no DAO interface leftovers. This class can be used to time ANY class that has an interface or virtual methods. Personally, I like to wrap and hide the usage of DynamicProxy and IInterceptor so that anyone who uses this class doesn't need to know to add a Castle library reference.  As far as they are concerned, they're using my interceptor.  If I change to a new library if a better one comes along, they're insulated. Now, all we have to do to use this is to tell it to wrap our ProductDao and it does the rest: 1: // wraps a new ProductDao with a timing interceptor with a threshold of 5 seconds 2: IProductDao dao = TimeThresholdInterceptor.Create<IProductDao>(new ProductDao(), 5000); Automatic decoration of all methods!  You can even refine the proxy so that it only intercepts certain methods. This is ideal for so many things.  These are just some of the interceptors we've dreamed up and use: Log parameters and returns of methods to XML for auditing. Block invocations to methods and return default value (stubbing). Throw exception if certain methods are called (good for blocking access to deprecated methods). Log entrance and exit of a method and the duration. Log a message if a method takes more than a given time threshold to execute. Whether you use DynamicProxy or some other technology, I hope you see the benefits this adds.  Does it completely eliminate all need for the Decorator pattern?  No, there may still be cases where you want to decorate a particular class with functionality that doesn't apply to the world at large. But for all those cases where you are using Decorator to add functionality that's truly generic.  I strongly suggest you give this a try!

  • Using TPL and PLINQ to raise performance of feed aggregator

    - by DigiMortal
    In this posting I will show you how to use Task Parallel Library (TPL) and PLINQ features to boost performance of simple RSS-feed aggregator. I will use here only very basic .NET classes that almost every developer starts from when learning parallel programming. Of course, we will also measure how every optimization affects performance of feed aggregator. Feed aggregator Our feed aggregator works as follows: Load list of blogs Download RSS-feed Parse feed XML Add new posts to database Our feed aggregator is run by task scheduler after every 15 minutes by example. We will start our journey with serial implementation of feed aggregator. Second step is to use task parallelism and parallelize feeds downloading and parsing. And our last step is to use data parallelism to parallelize database operations. We will use Stopwatch class to measure how much time it takes for aggregator to download and insert all posts from all registered blogs. After every run we empty posts table in database. Serial aggregation Before doing parallel stuff let’s take a look at serial implementation of feed aggregator. All tasks happen one after other. internal class FeedClient {     private readonly INewsService _newsService;     private const int FeedItemContentMaxLength = 255;       public FeedClient()     {          ObjectFactory.Initialize(container =>          {              container.PullConfigurationFromAppConfig = true;          });           _newsService = ObjectFactory.GetInstance<INewsService>();     }       public void Execute()     {         var blogs = _newsService.ListPublishedBlogs();           for (var index = 0; index <blogs.Count; index++)         {              ImportFeed(blogs[index]);         }     }       private void ImportFeed(BlogDto blog)     {         if(blog == null)             return;         if (string.IsNullOrEmpty(blog.RssUrl))             return;           var uri = new Uri(blog.RssUrl);         SyndicationContentFormat feedFormat;           feedFormat = SyndicationDiscoveryUtility.SyndicationContentFormatGet(uri);           if (feedFormat == SyndicationContentFormat.Rss)             ImportRssFeed(blog);         if (feedFormat == SyndicationContentFormat.Atom)             ImportAtomFeed(blog);                 }       private void ImportRssFeed(BlogDto blog)     {         var uri = new Uri(blog.RssUrl);         var feed = RssFeed.Create(uri);           foreach (var item in feed.Channel.Items)         {             SaveRssFeedItem(item, blog.Id, blog.CreatedById);         }     }       private void ImportAtomFeed(BlogDto blog)     {         var uri = new Uri(blog.RssUrl);         var feed = AtomFeed.Create(uri);           foreach (var item in feed.Entries)         {             SaveAtomFeedEntry(item, blog.Id, blog.CreatedById);         }     } } Serial implementation of feed aggregator downloads and inserts all posts with 25.46 seconds. Task parallelism Task parallelism means that separate tasks are run in parallel. You can find out more about task parallelism from MSDN page Task Parallelism (Task Parallel Library) and Wikipedia page Task parallelism. Although finding parts of code that can run safely in parallel without synchronization issues is not easy task we are lucky this time. Feeds import and parsing is perfect candidate for parallel tasks. We can safely parallelize feeds import because importing tasks doesn’t share any resources and therefore they don’t also need any synchronization. After getting the list of blogs we iterate through the collection and start new TPL task for each blog feed aggregation. internal class FeedClient {     private readonly INewsService _newsService;     private const int FeedItemContentMaxLength = 255;       public FeedClient()     {          ObjectFactory.Initialize(container =>          {              container.PullConfigurationFromAppConfig = true;          });           _newsService = ObjectFactory.GetInstance<INewsService>();     }       public void Execute()     {         var blogs = _newsService.ListPublishedBlogs();                var tasks = new Task[blogs.Count];           for (var index = 0; index <blogs.Count; index++)         {             tasks[index] = new Task(ImportFeed, blogs[index]);             tasks[index].Start();         }           Task.WaitAll(tasks);     }       private void ImportFeed(object blogObject)     {         if(blogObject == null)             return;         var blog = (BlogDto)blogObject;         if (string.IsNullOrEmpty(blog.RssUrl))             return;           var uri = new Uri(blog.RssUrl);         SyndicationContentFormat feedFormat;           feedFormat = SyndicationDiscoveryUtility.SyndicationContentFormatGet(uri);           if (feedFormat == SyndicationContentFormat.Rss)             ImportRssFeed(blog);         if (feedFormat == SyndicationContentFormat.Atom)             ImportAtomFeed(blog);                }       private void ImportRssFeed(BlogDto blog)     {          var uri = new Uri(blog.RssUrl);          var feed = RssFeed.Create(uri);           foreach (var item in feed.Channel.Items)          {              SaveRssFeedItem(item, blog.Id, blog.CreatedById);          }     }     private void ImportAtomFeed(BlogDto blog)     {         var uri = new Uri(blog.RssUrl);         var feed = AtomFeed.Create(uri);           foreach (var item in feed.Entries)         {             SaveAtomFeedEntry(item, blog.Id, blog.CreatedById);         }     } } You should notice first signs of the power of TPL. We made only minor changes to our code to parallelize blog feeds aggregating. On my machine this modification gives some performance boost – time is now 17.57 seconds. Data parallelism There is one more way how to parallelize activities. Previous section introduced task or operation based parallelism, this section introduces data based parallelism. By MSDN page Data Parallelism (Task Parallel Library) data parallelism refers to scenario in which the same operation is performed concurrently on elements in a source collection or array. In our code we have independent collections we can process in parallel – imported feed entries. As checking for feed entry existence and inserting it if it is missing from database doesn’t affect other entries the imported feed entries collection is ideal candidate for parallelization. internal class FeedClient {     private readonly INewsService _newsService;     private const int FeedItemContentMaxLength = 255;       public FeedClient()     {          ObjectFactory.Initialize(container =>          {              container.PullConfigurationFromAppConfig = true;          });           _newsService = ObjectFactory.GetInstance<INewsService>();     }       public void Execute()     {         var blogs = _newsService.ListPublishedBlogs();                var tasks = new Task[blogs.Count];           for (var index = 0; index <blogs.Count; index++)         {             tasks[index] = new Task(ImportFeed, blogs[index]);             tasks[index].Start();         }           Task.WaitAll(tasks);     }       private void ImportFeed(object blogObject)     {         if(blogObject == null)             return;         var blog = (BlogDto)blogObject;         if (string.IsNullOrEmpty(blog.RssUrl))             return;           var uri = new Uri(blog.RssUrl);         SyndicationContentFormat feedFormat;           feedFormat = SyndicationDiscoveryUtility.SyndicationContentFormatGet(uri);           if (feedFormat == SyndicationContentFormat.Rss)             ImportRssFeed(blog);         if (feedFormat == SyndicationContentFormat.Atom)             ImportAtomFeed(blog);                }       private void ImportRssFeed(BlogDto blog)     {         var uri = new Uri(blog.RssUrl);         var feed = RssFeed.Create(uri);           feed.Channel.Items.AsParallel().ForAll(a =>         {             SaveRssFeedItem(a, blog.Id, blog.CreatedById);         });      }        private void ImportAtomFeed(BlogDto blog)      {         var uri = new Uri(blog.RssUrl);         var feed = AtomFeed.Create(uri);           feed.Entries.AsParallel().ForAll(a =>         {              SaveAtomFeedEntry(a, blog.Id, blog.CreatedById);         });      } } We did small change again and as the result we parallelized checking and saving of feed items. This change was data centric as we applied same operation to all elements in collection. On my machine I got better performance again. Time is now 11.22 seconds. Results Let’s visualize our measurement results (numbers are given in seconds). As we can see then with task parallelism feed aggregation takes about 25% less time than in original case. When adding data parallelism to task parallelism our aggregation takes about 2.3 times less time than in original case. More about TPL and PLINQ Adding parallelism to your application can be very challenging task. You have to carefully find out parts of your code where you can safely go to parallel processing and even then you have to measure the effects of parallel processing to find out if parallel code performs better. If you are not careful then troubles you will face later are worse than ones you have seen before (imagine error that occurs by average only once per 10000 code runs). Parallel programming is something that is hard to ignore. Effective programs are able to use multiple cores of processors. Using TPL you can also set degree of parallelism so your application doesn’t use all computing cores and leaves one or more of them free for host system and other processes. And there are many more things in TPL that make it easier for you to start and go on with parallel programming. In next major version all .NET languages will have built-in support for parallel programming. There will be also new language constructs that support parallel programming. Currently you can download Visual Studio Async to get some idea about what is coming. Conclusion Parallel programming is very challenging but good tools offered by Visual Studio and .NET Framework make it way easier for us. In this posting we started with feed aggregator that imports feed items on serial mode. With two steps we parallelized feed importing and entries inserting gaining 2.3 times raise in performance. Although this number is specific to my test environment it shows clearly that parallel programming may raise the performance of your application significantly.

  • Tellago announces SQL Server 2008 R2 BI quick adoption programs

    - by Vishal
    During the last year, we (Tellago) have been involved in various business intelligence initiatives that leverage some emerging BI techniques such as self-service BI or complex event processing (CEP). Specifically, in the last few months, we have partnered with Microsoft to deliver a series of events across the country where we present the different technologies of the SQL Server 2008 R2 BI stack such as PowerPivot, StreamInsight, Ad-Hoc Reporting and Master Data Services. As part of those events, we try to go beyond the traditional technology presentation and provide a series of best practices and lessons we have learned on real world BI projects that leverage these technologies. Now that SQL Server 2008 R2 has been released to manufacturing, we have launched a series of quick adoption programs that are designed to help customers understand how they can embrace the newest additions to Microsoft's BI stack as part of their IT initiatives. The programs are also designed to help customers understand how the new SQL Server features interact with established technologies such as SQL Server Analysis Services or SQL Server Integration Services. We try to keep these adoption programs very practical by doing a lot of prototyping and design sessions that will give our customers a practical glimpse of the capabilities of the technologies and how they can fit in their enterprise architecture roadmap. Here is our official announcement (you can blame my business partner, BI enthusiast, and Tellago's CEO Elizabeth Redding for the marketing pitch ;)): Tellago Marks Microsoft's SQL Server 2008 R2 Launch With Business Intelligence Quick Adoption Program Microsoft launched SQL Server 2008 R2 last week, which delivers several breakthrough business intelligence (BI) capabilities that enable organizations to:  Efficiently process, analyze and mine data Improve IT and developer efficiency Enable highly scalable and well-managed Business Intelligence on a self-service basis for business users The release offers a new feature called PowerPivot, which enables self service BI through connecting business users directly to enterprise data sources and providing improved reporting and analytics. The release also offers Master Data Management which helps enterprises centrally manage critical data assets company-wide and across diverse systems, enabling increased integrity of information over time. Finally, the release includes StreamInsight, which is a framework for implementing Complex Event Processing (CEP) applications on the Microsoft platform. With StreamInsight, IT organizations can implement the infrastructure to process a large volume of events near real time, execute continuous queries against event streams and enable real time business intelligence. As a thought leader in the Business Intelligence community, Tellago has recognized the occasion by launching a series of quick adoption programs to enable the adoption of this new BI technology stack in your enterprise. Our Quick Adoption programs are designed to help you: Brainstorm BI solution options  Architect initial infrastructure components Prototype key features of a solution As a 2-3 day program, our approach is more efficient and cost effective than a traditional Proof of Concept because it allows you to understand the new SQL Server 2008 R2 feature set  while seeing directly how you can leverage it for your business intelligence needs. If you are interested in learning more about the BI capabilities of Microsoft's Business Intelligence stack, including SQL Server 2008 R2, we can help.  As industry experts and software content advisers to Microsoft, Tellago is the place where ideas meet technology expertise.  Let us help you see for yourself the advantages that you can gain from Microsoft's  SQL Server 2008 R2.

  • What should you bring to the table as a Software Architect?

    - by Ahmad Mageed
    There have been many questions with good answers about the role of a Software Architect (SA) on StackOverflow and Programmers SE. I am trying to ask a slightly more focused question than those. The very definition of a SA is broad so for the sake of this question let's define a SA as follows: A Software Architect guides the overall design of a project, gets involved with coding efforts, conducts code reviews, and selects the technologies to be used. In other words, I am not talking about managerial rest and vest at the crest (further rhyming words elided) types of SAs. If I were to pursue any type of SA position I don't want to be away from coding. I might sacrifice some time to interface with clients and Business Analysts etc., but I am still technically involved and I'm not just aware of what's going on through meetings. With these points in mind, what should a SA bring to the table? Should they come in with a mentality of "laying down the law" (so to speak) and enforcing the usage of certain tools to fit "their way," i.e., coding guidelines, source control, patterns, UML documentation, etc.? Or should they specify initial direction and strategy then be laid back and jump in as needed to correct the ship's direction? Depending on the organization this might not work. An SA who relies on TFS to enforce everything may struggle to implement their plan at an employer that only uses StarTeam. Similarly, an SA needs to be flexible depending on the stage of the project. If it's a fresh project they have more choices, whereas they might have less for existing projects. Here are some SA stories I have experienced as a way of sharing some background in hopes that answers to my questions might also shed some light on these issues: I've worked with an SA who code reviewed literally every single line of code of the team. The SA would do this for not just our project but other projects in the organization (imagine the time spent on this). At first it was useful to enforce certain standards, but later it became crippling. FxCop was how the SA would find issues. Don't get me wrong, it was a good way to teach junior developers and force them to think of the consequences of their chosen approach, but for senior developers it was seen as somewhat draconian. One particular SA was against the use of a certain library, claiming it was slow. This forced us to write tons of code to achieve things differently while the other library would've saved us a lot of time. Fast forward to the last month of the project and the clients were complaining about performance. The only solution was to change certain functionality to use the originally ignored approach despite early warnings from the devs. By that point a lot of code was thrown out and not reusable, leading to overtime and stress. Sadly the estimates used for the project were based on the old approach which my project was forbidden from using so it wasn't an appropriate indicator for estimation. I would hear the PM say "we've done this before," when in reality they had not since we were using a new library and the devs working on it were not the same devs used on the old project. The SA who would enforce the usage of DTOs, DOs, BOs, Service layers and so on for all projects. New devs had to learn this architecture and the SA adamantly enforced usage guidelines. Exceptions to usage guidelines were made when it was absolutely difficult to follow the guidelines. The SA was grounded in their approach. Classes for DTOs and all CRUD operations were generated via CodeSmith and database schemas were another similar ball of wax. However, having used this setup everywhere, the SA was not open to new technologies such as LINQ to SQL or Entity Framework. I am not using this post as a platform for venting. There were positive and negative aspects to my experiences with the SA stories mentioned above. My questions boil down to: What should an SA bring to the table? How can they strike a balance in their decision making? Should one approach an SA job (as defined earlier) with the mentality that they must enforce certain ground rules? Anything else to consider? Thanks! I'm sure these job tasks are easily extended to people who are senior devs or technical leads, so feel free to answer at that capacity as well.

  • SQL Saturday 43 in Redmond

    - by AjarnMark
    I attended my first SQLSaturday a couple of days ago, SQLSaturday #43 in Redmond (at Microsoft).  I got there really early, primarily because I forgot how fast I can get there from my home when nobody else is on the road.  On a weekday in rush hour traffic, that would have taken two hours to get there.  I gave myself 90 minutes, and actually got there in about 45.  Crazy! I made the mistake of going to the main Microsoft campus, but that’s not where the event was being held.  Instead it was in a big Microsoft conference center on the other side of the highway.  Fortunately, I had the address with me and quickly realized my mistake.  When I got back on track, I noticed that there were bright yellow signs out on the street corner that looked like they said they were for SOL Saturday, which actually was appropriate since it was the sunniest day around here in a long time. Since I was there so early, the registration was just getting setup, so I found Greg Larsen who was coordinating things and offered to help.  He put me to work with a group of people organizing the pre-printed raffle tickets and stuffing swag bags. I had never been to a SQLSaturday before this one, so I wasn’t exactly sure what to expect even though I have read about a few on some blogs.  It makes sense that each one will be a little bit different since they are almost completely volunteer driven, and the whole concept is still in its early stages.  I have been to the PASS Summit for the last several years, and was hoping for a smaller version of that.  Now, it’s not really fair to compare one free day of training run entirely by volunteers with a multi-day, $1,000+ event put on under the direction of a professional event management company.  But there are some parallels. At this SQLSaturday, there was no opening general session, just coffee and pastries in the common area / expo hallway and straight into the first group of sessions.  I don’t know if that was because there was no single room large enough to hold everyone, or for other reasons.  This worked out okay, but the organization guy in me would have preferred to have even a 15 minute welcome message from the organizers with a little overview of the day.  Even something as simple as, “Thanks to persons X, Y, and Z for helping put this together…Sessions will start in 20 minutes and are all in rooms down this hallway…the bathrooms are on the other side of the conference center…lunch today is pizza and we would like to thank sponsor Q for providing it.”  It doesn’t need to be much, certainly not a full-blown Keynote like at the PASS Summit, but something to use as a rallying point to pull everyone together and get the day off to an official start would be nice.  Again, there may have been logistical reasons why that was not feasible here.  I’m just putting out my thoughts for other SQLSaturday coordinators to consider. The event overall was great.  I believe that there were over 300 in attendance, and everything seemed to run smoothly.  At least from an attendee’s point of view where there was plenty of muffins in the morning and pizza in the afternoon, with plenty of pop to drink.  And hey, if you’ve got the food and drink covered, a lot of other stuff could go wrong and people will be very forgiving.  But as I said, everything appeared to run pretty smoothly, at least until Buck Woody showed up in his Oracle shirt.  Other than that, the volunteers did a great job! I was a little surprised by how few people in my own backyard that I know.  It makes sense if you really think about it, given how many companies must be using SQL Server around here.  I guess I just got spoiled coming into the PASS Summit with a few contacts that I already knew would be there.  Perhaps I have been spending too much time with too few people at the Summits and I need to step out and meet more folks.  Of course, it also is different since the Summit is the big national event and a number of the folks I know are spread out across the country, so the Summit is the only time we’re all in the same place at the same time.  I did make a few new contacts at SQLSaturday, and bumped into a couple of people that I knew (and a couple others that I only knew from Twitter, and didn’t even realize that they were here in the area). Other than the sheer entertainment value of Buck Woody’s session, the one that was probably the greatest value for me was a quick introduction to PowerShell.  I have not done anything with it yet, but I think it will be a good tool to use to implement my plans for automated database recovery testing.  I saw just enough at the session to take away some of the intimidation factor, and I am getting ready to jump in and see what I can put together in the next few weeks.  And that right there made the investment worthwhile.  So I encourage you, if you have the opportunity to go to a SQLSaturday event near you, go for it!

  • Getting Internet Explorer to Open Different Sets of Tabs Based on the Day of the Week

    - by Akemi Iwaya
    If you have to use Internet Explorer for work and need to open a different set of work-specific tabs every day, is there a quick and easy way to do it instead of opening each one individually? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader bobSmith1432 is looking for a quick and easy way to open different daily sets of tabs in Internet Explorer for his work: When I open Internet Explorer on different days of the week, I want different tabs to be opened automatically. I have to run different reports for work each day of the week and it takes a lot of time to open the 5-10 tabs I use to run the reports. It would be a lot faster if, when I open Internet Explorer, the tabs I needed would automatically load and be ready. Is there a way to open 5-10 different tabs in Internet Explorer depending on the day of the week? Example: Monday – 6 Accounting Pages Tuesday – 7 Billing Pages Wednesday – 5 HR Pages Thursday – 10 Schedule Pages Friday – 8 Work Summary/Order Pages Is there an easier way for Bob to get all those tabs to load and be ready to go each day instead of opening them individually every time? The Answer SuperUser contributor Julian Knight has a simple, non-script solution for us: Rather than trying the brute force method, how about a work around? Open up each set of tabs either in different windows, or one set at a time, and save all tabs to bookmark folders. Put the folders on the bookmark toolbar for ease of access. Each day, right-click on the appropriate folder and click on ‘Open in tab group’ to open all the tabs. You could put all the day folders into a top-level folder to save space if you want, but at the expense of an extra click to get to them. If you really must go further, you need to write a program or script to drive Internet Explorer. The easiest way is probably writing a PowerShell script. Special Note: There are various scripts shared on the discussion page as well, so the solution shown above is just one possibility out of many. If you love the idea of using scripts for a function like this, then make sure to browse on over to the discussion page to see the various ones SuperUser members have shared!

  • What GUI are there for Axel or for other such downloaders that use multiple connections?

    - by cipricus
    In order to enjoy my maximum download speed, I use and like Axel very much, but from time to time I download multiple files and having so many windows opened has some disadvantages. I use Axel with FlashGot in Firefox (Seamonkey etc) but I would like to add a GUI for that, and possibly have multiple downloads in a nice list as in any civil downloader. I am not aware of a GUI for Axel that works. Axel-kapt crashes. (A question on how to use it properly in Ubuntu got only one somewhat dismissive answer by yours truly...) Gaxel just opens a window with empty fields that I have to manually fill (which beats the purpose). I would like to know how to install something like Gwget which is described here, in an old answer as an alternative (but Gwget itself might be too old too). Help!

  • Oracle on Oracle: Is that all?

    - by Darin Pendergraft
    On October 17th, I posted a short blog and a podcast interview with Chirag Andani, talking about how Oracle IT uses its own IDM products. Blog link here. In response, I received a comment from reader Jaime Cardoso ([email protected]) who posted: “- You could have talked about how by deploying Oracle's Open standards base technology you were able to integrate any new system in your infrastructure in days. - You could have talked about how by deploying federation you were enabling the business side to keep all their options open in terms of companies to buy and sell while maintaining perfect employee and customer's single view. - You could have talked about how you are now able to cut response times to your audit and security teams into 1/10th of your former times Instead you spent 6 minutes talking about single sign on and self provisioning? If I didn't knew your IDM offer so well I would now be wondering what its differences from Microsoft's offer was. Sorry for not giving a positive comment here but, please your IDM suite is very good and, you simply aren't promoting it well enough” So I decided to send Jaime a note asking him about his experience, and to get his perspective on what makes the Oracle products great. What I found out is that Jaime is a very experienced IDM Architect with several major projects under his belt. Darin Pendergraft: Can you tell me a bit about your experience? How long have you worked in IT, and what is your IDM experience? Jaime Cardoso: I started working in "serious" IT in 1998 when I became Netscape's technical specialist in Portugal. Netscape Portugal didn't exist so, I was working for their VAR here. Most of my work at the time was with Netscape's mail server and LDAP server. Since that time I've been bouncing between the system's side like Sun resellers, Solaris stuff and even worked with Sun's Engineering in the making of an Hierarchical Storage Product (Sun CIS if you know it) and the application's side, mostly in LDAP and IDM. Over the years I've been doing support, service delivery and pre-sales / architecture design of IDM solutions in most big customers in Portugal, to name a few projects: - The first European deployment of Sun Access Manager (SAPO – Portugal Telecom) - The identity repository of 5/5 of the Biggest Portuguese banks - The Portuguese government federation of services project DP: OK, in your blog response, you mentioned 3 topics: 1. Using Oracle's standards based architecture; (you) were able to integrate any new system in days: can you give an example? What systems, how long did it take, number of apps/users/accounts/roles etc. JC: It's relatively easy to design a user management strategy for a static environment, or if you simply assume that you're an <insert vendor here> shop and all your systems will bow to that vendor's will. We've all seen that path, the use of proprietary technologies in interoperability solutions but, then reality kicks in. As an ISP I recall that I made the technical decision to use Active Directory as a central authentication system for the entire IT infrastructure. Clients, systems, apps, everything was there. As a good part of the systems and apps were running on UNIX, then a connector became needed in order to have UNIX boxes to authenticate against AD. And, that strategy worked but, each new machine required the component to be installed, monitoring had to be made for that component and each new app had to be independently certified. A self care user portal was an ongoing project, AD access assumes the client is inside the domain, something the ISP's customers (and UNIX boxes) weren't nor had any intention of ever being. When the Windows 2008 rollout was done, Microsoft changed the Active Directory interface. The Windows administrators didn't have enough know-how about directories and the way systems outside the MS world behaved so, on the go live, things weren't properly tested and a general outage followed. Several hours and 1 roll back later, everything was back working. But, the ISP still had to change all of its applications to work with the new access methods and reset the effort spent on the self service user portal. To keep with the same strategy, they would also have to trust Microsoft not to change interfaces again. Simply by putting up an Oracle LDAP server in the middle and replicating the user info from the AD into LDAP, most of the problems went away. Even systems for which no AD connector existed had PAM in them so, integration was made at the OS level, fully supported by the OS supplier. Sun Identity Manager already had a self care portal, combined with a user workflow so, all the clearances had to be given before the account was created or updated. Adding a new system as a client for these authentication services was simply a new checkbox in the OS installer and, even True64 systems were, for the first time integrated also with a 5 minute work of a junior system admin. True, all the windows clients and MS apps still went to the AD for their authentication needs so, from the start everybody knew that they weren't 100% free of migration pains but, now they had a single point of problems to look at. If you're looking for numbers: - 500K directory entries (users) - 2-300 systems After the initial setup, I personally integrated about 20 systems / apps against LDAP in 1 day while being watched by the different IT teams. The internal IT staff did the rest. DP: 2. Using Federation allows the business to keep options open for buying and selling companies, and yet maintain a single view for both employee and customer. What do you mean by this? Can you give an example? JC: The market is dynamic. The company that's being bought today tomorrow will be sold again. Companies that spread on different markets may see the regulator forcing a sale of part of a company due to monopoly reasons and companies that are in multiple countries have to comply with different legislations. Our job, as IT architects, while addressing the customers and employees authentication services, is quite hard and, quite contrary. On one hand, we need to give access to all of our employees to the relevant systems, apps and resources and, we already have marketing talking with us trying to find out who's a customer of the bough company but not from ours to address. On the other hand, we have to do that and keep in mind we may have to break up all that effort and that different countries legislation may became a problem with a full integration plan. That's a job for user Federation. you don't want to be the one who's telling your President that he will sell that business unit without it's customer's database (making the deal worth a lot less) or that the buyer will take with him a copy of your entire customer's database. Federation enables you to start controlling permissions to users outside of your traditional authentication realm. So what if the people of that company you just bought are keeping their old logins? Do you want, because of that, to have a dedicated system for their expenses reports? And do you want to keep their sales (and pre-sales) people out of the loop in terms of your group's path? Control the information flow, establish a Federation trust circle and give access to your apps to users that haven't (yet?) been brought into your internal login systems. You can still see your users in a unified view, you obviously control if a user has access to any particular application, either that user is in your local database or stored in a directory on the other side of the world. DP: 3. Cut response times of audit and security teams to 1/10. Is this a real number? Can you give an example? JC: No, I don't have any backing for this number. One of the companies I did system Administration for has a SOX compliance policy in place (I remind you that I live in Portugal so, this definition of SOX may be somewhat different from what you're used to) and, every time the audit team says they'll do another audit, we have to negotiate with them the size of the sample and we spend about 15 man/days gathering all the required info they ask. I did some work with Sun's Identity auditor and, from what I've been seeing, Oracle's product is even better and, I've seen that most of the information they ask would have been provided in a few hours with the help of this tool. I do stand by what I said here but, to be honest, someone from Identity Auditor team would do a much better job than me explaining this time savings. Jaime is right: the Oracle IDM products have a lot of business value, and Oracle IT is using them for a lot more than I was able to cover in the short podcast that I posted. I want to thank Jaime for his comments and perspective. We want these blog posts to be informative and honest – so if you have feedback for the Oracle IDM team on any topic discussed here, please post your comments below.

  • ORACLE RIGHTNOW DYNAMIC AGENT DESKTOP CLOUD SERVICE - Putting the Dynamite into Dynamic Agent Desktop

    - by Andreea Vaduva
    Untitled Document There’s a mountain of evidence to prove that a great contact centre experience results in happy, profitable and loyal customers. The very best Contact Centres are those with high first contact resolution, customer satisfaction and agent productivity. But how many companies really believe they are the best? And how many believe that they can be? We know that with the right tools, companies can aspire to greatness – and achieve it. Core to this is ensuring their agents have the best tools that give them the right information at the right time, so they can focus on the customer and provide a personalised, professional and efficient service. Today there are multiple channels through which customers can communicate with you; phone, web, chat, social to name a few but regardless of how they communicate, customers expect a seamless, quality experience. Most contact centre agents need to switch between lots of different systems to locate the right information. This hampers their productivity, frustrates both the agent and the customer and increases call handling times. With this in mind, Oracle RightNow has designed and refined a suite of add-ins to optimize the Agent Desktop. Each is designed to simplify and adapt the agent experience for any given situation and unify the customer experience across your media channels. Let’s take a brief look at some of the most useful tools available and see how they make a difference. Contextual Workspaces: The screen where agents do their job. Agents don’t want to be slowed down by busy screens, scrolling through endless tabs or links to find what they’re looking for. They want quick, accurate and easy. Contextual Workspaces are fully configurable and through workspace rules apply if, then, else logic to display only the information the agent needs for the issue at hand . Assigned at the Profile level, different levels of agent, from a novice to the most experienced, get a screen that is relevant to their role and responsibilities and ensures their job is done quickly and efficiently the first time round. Agent Scripting: Sometimes, agents need to deliver difficult or sensitive messages while maximising the opportunity to cross-sell and up-sell. After all, contact centres are now increasingly viewed as revenue generators. Containing sophisticated branching logic, scripting helps agents to capture the right level of information and guides the agent step by step, ensuring no mistakes, inconsistencies or missed opportunities. Guided Assistance: This is typically used to solve common troubleshooting issues, displaying a series of question and answer sets in a decision-tree structure. This means agents avoid having to bookmark favourites or rely on written notes. Agents find particular value in these guides - to quickly craft chat and email responses. What’s more, by publishing guides in answers on support pages customers, can resolve issues themselves, without needing to contact your agents. And b ecause it can also accelerate agent ramp-up time, it ensures that even novice agents can solve customer problems like an expert. Desktop Workflow: Take a step back and look at the full customer interaction of your agents. It probably spans multiple systems and multiple tasks. With Desktop Workflows you control the design workflows that span the full customer interaction from start to finish. As sequences of decisions and actions, workflows are unique in that they can create or modify different records and provide automation behind the scenes. This means your agents can save time and provide better quality of service by having the tools they need and the relevant information as required. And doing this boosts satisfaction among your customers, your agents and you – so win, win, win! I have highlighted above some of the tools which can be used to optimise the desktop; however, this is by no means an exhaustive list. In approaching your design, it’s important to understand why and how your customers contact you in the first place. Once you have this list of “whys” and “hows”, you can design effective policies and procedures to handle each category of problem, and then implement the right agent desktop user interface to support them. This will avoid duplication and wasted effort. Five Top Tips to take away: Start by working out “why” and “how” customers are contacting you. Implement a clean and relevant agent desktop to support your agents. If your workspaces are getting complicated consider using Desktop Workflow to streamline the interaction. Enhance your Knowledgebase with Guides. Agents can access them proactively and can be published on your web pages for customers to help themselves. Script any complex, critical or sensitive interactions to ensure consistency and accuracy. Desktop optimization is an ongoing process so continue to monitor and incorporate feedback from your agents and your customers to keep your Contact Centre successful.   Want to learn more? Having attending the 3-day Oracle RightNow Customer Service Administration class your next step is to attend the Oracle RightNow Customer Portal Design and 2-day Dynamic Agent Desktop Administration class.

  • Exam 70-541 - TS: Microsoft Windows SharePoint Services 3.0 - Application Development

    - by DigiMortal
    Today I passed Microsoft exam 70-541: Microsoft Windows SharePoint Services 3.0 - Application Development. This exam gives you MCTS certificate. In this posting I will talk about the exam and also give some suggestions about books to read when preparing for exam. About exam This exam was good one I think. The questions were not hard and also not too easy. Just enough to make sure you really know what you do when working with SharePoint. Or at least to make sure you how things work. After couple of years active SharePoint coding this exam needs no additional preparation. The questions covered very different topics like alerts, features, web parts, site definitions, event receivers, workflows, web services and deployments. There are 59 questions in the exam (this information is available in internet) and you have time a little bit more than two hours. It took me about 40 minutes to get questions answered and reviewed. I strongly suggest you to study the parts of WSS 3.0 you don’t know yet and write some code to find out how to use these things through SharePoint API. Good reading For guys with less experience there are some good books to suggest. Take one or both of these books because there are no official study materials or training kits available for this exam. One of my colleagues who is less experienced than me suggested Inside Microsoft Windows SharePoint Services 3.0 by Ted Pattison and Daniel Larson. He told me that he found this book most useful for him to pass this exam.   When I started with SharePoint Services 3.0 my first book was Developer’s Guide To The Windows SharePoint Services v3 Platform by Todd C. Bleeker. It helped me getting started and later it was my main handbook for some time. Of course, there are many other good books and I suggest you to take what you find. Of course, before buying something I suggest you to discuss with guys who have read the book before. And make sure you mention that you are preparing for exam.   Conclusion If you are experienced SharePoint developer then this exam needs no preparation. Okay, some preparation is always good but if you don’t have time you are still able to pass this exam. If you are not experienced SharePoint developer then study before taking this exam – it is not easy stuff for novices. But if you pass this exam you can proudly say – yes, I know something about SharePoint! :)

  • Is GParted safe?

    - by Olivier Pons
    I want to resize my partitions: I have 3 partitions: Ubuntu 10.04 Windows Seven Ubuntu 11.10 It's booting with the boot installed by the Ubuntu 11.10 version. I want to expand (only expand) all the 3 partitions. My HD is 1,8 Tb so it's big and I have no possibility to save before expanding. So my question is: if you tell me GParted work 99,99 % of the time, I'm willing to take the risk. If you tell me GParted work 90 % of the time, I won't take that risk.
