• Click on notification starts activity twice

  - by Karussell

  I'm creating a notification from a service with the following code: NotificationManager notificationManager = (NotificationManager) ctx .getSystemService(Context.NOTIFICATION_SERVICE); CharSequence tickerText = "bla ..."; long when = System.currentTimeMillis(); Notification notification = new Notification(R.drawable.icon, tickerText, when); Intent notificationIntent = new Intent(ctx, SearchActivity.class). putExtra(SearchActivity.INTENT_SOURCE, MyNotificationService.class.getSimpleName()); PendingIntent contentIntent = PendingIntent.getActivity(ctx, 0, notificationIntent, 0); notification.setLatestEventInfo(ctx, ctx.getString(R.string.app_name), tickerText, contentIntent); notification.flags |= Notification.FLAG_AUTO_CANCEL; notificationManager.notify(1, notification); The logs clearly says that the the method startActivity is called twice times: 04-02 23:48:06.923: INFO/ActivityManager(2466): Starting activity: Intent { act=android.intent.action.SEARCH cmp=com.xy/.SearchActivity bnds=[0,520][480,616] (has extras) } 04-02 23:48:06.923: WARN/ActivityManager(2466): startActivity called from non-Activity context; forcing Intent.FLAG_ACTIVITY_NEW_TASK for: Intent { act=android.intent.action.SEARCH cmp=com.xy/.SearchActivity bnds=[0,520][480,616] (has extras) } 04-02 23:48:06.958: INFO/ActivityManager(2466): Starting activity: Intent { act=android.intent.action.SEARCH cmp=com.xy/.SearchActivity bnds=[0,0][480,96] (has extras) } 04-02 23:48:06.958: WARN/ActivityManager(2466): startActivity called from non-Activity context; forcing Intent.FLAG_ACTIVITY_NEW_TASK for: Intent { act=android.intent.action.SEARCH cmp=com.xy/.SearchActivity bnds=[0,0][480,96] (has extras) } 04-02 23:48:07.087: INFO/notification(5028): onStartCmd: received start id 2: Intent { cmp=com.xy/.NotificationService } 04-02 23:48:07.310: INFO/notification(5028): onStartCmd: received start id 3: Intent { cmp=com.xy/.NotificationService } 04-02 23:48:07.392: INFO/ActivityManager(2466): Displayed activity com.xy/.SearchActivity: 462 ms (total 462 ms) 04-02 23:48:07.392: INFO/ActivityManager(2466): Displayed activity com.xy/.SearchActivity: 318 ms (total 318 ms) Why are they started twice? There are two identical questions on stackoverflow: here and here. But they do not explain what the initial issue could be and they do not work for me. E.g. changing to launchMode singleTop is not appropriated for me and it should work without changing launchMode according to the official docs (see Invoking the search dialog). Nevertheless I also tried to add the following flags to notificationIntent Intent.FLAG_ACTIVITY_CLEAR_TOP | PendingIntent.FLAG_UPDATE_CURRENT but the problem remains the same.

• How do I query delegation properties of an active directory user account?

  - by Mark J Miller

  I am writing a utility to audit the configuration of a WCF service. In order to properly pass credentials from the client, thru the WCF service back to the SQL back end the domain account used to run the service must be configured in Active Directory with the setting "Trust this user for delegation" (Properties - "Delegation" tab). Using C#, how do I access the settings on this tab in Active Directory. I've spent the last 5 hours trying to track this down on the web and can't seem to find it. Here's what I've done so far: using (Domain domain = Domain.GetCurrentDomain()) { Console.WriteLine(domain.Name); // get domain "dev" from MSSQLSERVER service account DirectoryEntry ouDn = new DirectoryEntry("LDAP://CN=Users,dc=dev,dc=mydomain,dc=lcl"); DirectorySearcher search = new DirectorySearcher(ouDn); // get sAMAccountName "dev.services" from MSSQLSERVER service account search.Filter = "(sAMAccountName=dev.services)"; search.PropertiesToLoad.Add("displayName"); search.PropertiesToLoad.Add("userAccountControl"); SearchResult result = search.FindOne(); if (result != null) { Console.WriteLine(result.Properties["displayName"][0]); DirectoryEntry entry = result.GetDirectoryEntry(); int userAccountControlFlags = (int)entry.Properties["userAccountControl"].Value; if ((userAccountControlFlags & (int)UserAccountControl.TRUSTED_FOR_DELEGATION) == (int)UserAccountControl.TRUSTED_FOR_DELEGATION) Console.WriteLine("TRUSTED_FOR_DELEGATION"); else if ((userAccountControlFlags & (int)UserAccountControl.TRUSTED_TO_AUTH_FOR_DELEGATION) == (int)UserAccountControl.TRUSTED_TO_AUTH_FOR_DELEGATION) Console.WriteLine("TRUSTED_TO_AUTH_FOR_DELEGATION"); else if ((userAccountControlFlags & (int)UserAccountControl.NOT_DELEGATED) == (int)UserAccountControl.NOT_DELEGATED) Console.WriteLine("NOT_DELEGATED"); foreach (PropertyValueCollection pvc in entry.Properties) { Console.WriteLine(pvc.PropertyName); for (int i = 0; i < pvc.Count; i++) { Console.WriteLine("\t{0}", pvc[i]); } } } } The "userAccountControl" does not seem to be the correct property. I think it is tied to the "Account Options" section on the "Account" tab, which is not what we're looking for but this is the closest I've gotten so far. The justification for all this is: We do not have permission to setup the service in QA or in Production, so along with our written instructions (which are notoriously only followed in partial) I am creating a tool that will audit the setup (WCF and SQL) to determine if the setup is correct. This will allow the person deploying the service to run this utility and verify everything is setup correctly - saving us hours of headaches and reducing downtime during deployment.

• problem with struts actions and redirections

  - by Casey

  I am trying to update a simple web app that was built with struts2, jsp and standard servlets. I am trying to redirect a url to a specific action but can't seem to get it to work right. For example, the url that is correct is: http://localhost:8080/theapp/lookup/search.action Here is my web.xml: <?xml version="1.0" encoding="ISO-8859-1"?> <!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd"><web-app> <display-name>theapp</display-name> <filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.FilterDispatcher </filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <listener> <listener-class> org.springframework.web.context.ContextLoaderListener </listener-class> </listener> And here is my struts.xml: <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <default-action-ref name="search" /> <action name="search" method="search" class="com.theapp.SearchAction" > <result>index.jsp</result> <result name="input" >index.jsp</result> <result name="error" type="redirect">site_locator_mobile/error.action</result> </action> The problem here is that if I don't specify the correct url as above, I just get the index.jsp file, but without any properties in index.jsp being processed because the information is contained in the servlet. What I would like to is if someone just entered: http://localhost:8080/theapp/lookup/ than they would be taken to: http://localhost:8080/theapp/lookup/search.action Thanks

• How to handle very frequent updates to a Lucene index

  - by fsm

  I am trying to prototype an indexing/search application which uses very volatile indexing data sources (forums, social networks etc), here are some of the performance requirements, Very fast turn-around time (by this I mean that any new data (such as a new message on a forum) should be available in the search results very soon (less than a minute)) I need to discard old documents on a fairly regular basis to ensure that the search results are not dated. Last but not least, the search application needs to be responsive. (latency on the order of 100 milliseconds, and should support at least 10 qps) All of the requirements I have currently can be met w/o using Lucene (and that would let me satisfy all 1,2 and 3), but I am anticipating other requirements in the future (like search relevance etc) which Lucene makes easier to implement. However, since Lucene is designed for use cases far more complex than the one I'm currently working on, I'm having a hard time satisfying my performance requirements. Here are some questions, a. I read that the optimize() method in the IndexWriter class is expensive, and should not be used by applications that do frequent updates, what are the alternatives? b. In order to do incremental updates, I need to keep committing new data, and also keep refreshing the index reader to make sure it has the new data available. These are going to affect 1 and 3 above. Should I try duplicate indices? What are some common approaches to solving this problem? c. I know that Lucene provides a delete method, which lets you delete all documents that match a certain query, in my case, I need to delete all documents which are older than a certain age, now one option is to add a date field to every document and use that to delete documents later. Is it possible to do range queries on document ids (I can create my own id field since I think that the one created by lucene keeps changing) to delete documents? Is it any faster than comparing dates represented as strings? I know these are very open questions, so I am not looking for a detailed answer, I will try to treat all of your answers as suggestions and use them to inform my design. Thanks! Please let me know if you need any other information.

• Exception from Response.Redirect?

  - by allencoded

  I keep getting an error: A first chance exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll An exception of type 'System.Threading.ThreadAbortException' occurred in mscorlib.dll but was not handled in user code The thread '' (0x27ee4) has exited with code 0 (0x0). I was told it was related to this: protected void Button1_Click(object sender, EventArgs e) { Response.Redirect("Results.aspx?Keywords=" + searchString.Text); } I figured it may help to include my complete code. The code above is the only C# code on my first asp page. That code relates to this code on this page. It is also the only C# code I have on my second page. I am simply just trying to pass a keyword from a search form to this block of code: if (Request.QueryString["Keywords"] != null){ string keywords = Request.QueryString["Keywords"]; string myAppID = "HIDDEN"; var xml = XDocument.Load("http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=findItemsByKeywords&SERVICE-VERSION=1.0.0&SECURITY-APPNAME=" + myAppID + "&RESPONSE-DATA-FORMAT=XML&REST-PAYLOAD&keywords=" + keywords + "&paginationInput.entriesPerPage=5"); XNamespace ns = "http://www.ebay.com/marketplace/search/v1/services"; var titles = from item in xml.Root.Descendants(ns + "title") select new{ title = xml.Descendants(ns + "title").Select (x => x.Value), }; foreach (var item in titles){ Label1.Text += item; } } This block of code calls the keyword value and uses it in an api to perform a search. The code of the xml(api) formats like this: <findItemsByKeywordsResponse xmlns="http://www.ebay.com/marketplace/search/v1/services"> <searchReslut count="5"> <item> <title></title> </item> <item> <title></title> </item> <item> <title></title> </item> Why am I getting this error how do you fix it?

• Why the only hidden field that is being filled from GET action is not being passed in model?

  - by user1807954

  Sorry for the long title, I didn't know how to make it any shorter. My code: My model: public class CarFilter { public String carMake { get; set; } public String carModel { get; set; } public String carEdition { get; set; } . . . public String SortBy { get; set; } } public class CarSearch : CarFilter { public List<Car> Car { get; set; } } My controller: public ActionResult SearchResult(CarSearch search) { var cars = from d in db.Cars select d; if (Request.HttpMethod == "POST") { search.SortBy = "Price"; } search.Car = new List<Car>(); search.Car.AddRange(cars); var temp = new List<CarSearch>(); temp.Add(search); return View(temp); } My Index view (where user filters results): @model IEnumerable<Cars.Models.CarSearch> @using (Html.BeginForm("SearchResult", "Home", FormMethod.Post)){..forms and other stuff..} My SearchResult view (where user sees the results of filtration): @model IEnumerable<Cars.Models.CarSearch> @using (Html.BeginForm("SearchResult", "Home", FormMethod.Get)) { @Html.Hidden("carMake") @Html.Hidden("carModel") @Html.Hidden("carEdition") . . . @Html.Hidden("SortBy", temp.SortBy) <input name="SortBy" class="buttons" type="submit" value="Make"/> My goal What I'm trying to do is when user clicked on sort by Make it will have to GET back all the variables in hidden field back to the SearchResult action in order to sort the result (same filtered results). Result Is: <input id="SortBy" name="SortBy" type="hidden" value=""/>. The value is null and it's not being passed but all the other hidden fields such as carMake and etc have value. But when I use foreach it works perfect. Question Why is this like this? the SortBy is in the same model class as other fields in the view. The only difference is that SortBy is not being filled in the Index view with other fields, instead it's being filled in controller action. What is the explanation for this? Am I missing any C# definition or something such as dynamic objects or something?

• Indexing on only part of a field in MongoDB

  - by Rob Hoare

  Is there a way to create an index on only part of a field in MongoDB, for example on the first 10 characters? I couldn't find it documented (or asked about on here). The MySQL equivalent would be CREATE INDEX part_of_name ON customer (name(10));. Reason: I have a collection with a single field that varies in length from a few characters up to over 1000 characters, average 50 characters. As there are a hundred million or so documents it's going to be hard to fit the full index in memory (testing with 8% of the data the index is already 400MB, according to stats). Indexing just the first part of the field would reduce the index size by about 75%. In most cases the search term is quite short, it's not a full-text search. A work-around would be to add a second field of 10 (lowercased) characters for each item, index that, then add logic to filter the results if the search term is over ten characters (and that extra field is probably needed anyway for case-insensitive searches, unless anybody has a better way). Seems like an ugly way to do it though. [added later] I tried adding the second field, containing the first 12 characters from the main field, lowercased. It wasn't a big success. Previously, the average object size was 50 bytes, but I forgot that includes the _id and other overheads, so my main field length (there was only one) averaged nearer to 30 bytes than 50. Then, the second field index contains the _id and other overheads. Net result (for my 8% sample) is the index on the main field is 415MB and on the 12 byte field is 330MB - only a 20% saving in space, not worthwhile. I could duplicate the entire field (to work around the case insensitive search problem) but realistically it looks like I should reconsider whether MongoDB is the right tool for the job (or just buy more memory and use twice as much disk space). [added even later] This is a typical document, with the source field, and the short lowercased field: { "_id" : ObjectId("505d0e89f56588f20f000041"), "q" : "Continental Airlines", "f" : "continental " } Indexes: db.test.ensureIndex({q:1}); db.test.ensureIndex({f:1}); The 'f" index, working on a shorter field, is 80% of the size of the "q" index. I didn't mean to imply I included the _id in the index, just that it needs to use that somewhere to show where the index will point to, so it's an overhead that probably helps explain why a shorter key makes so little difference. Access to the index will be essentially random, no part of it is more likely to be accessed than any other. Total index size for the full file will likely be 5GB, so it's not extreme for that one index. Adding some other fields for other search cases, and their associated indexes, and copies of data for lower case, does start to add up, which I why I started looking into a more concise index.

• The broken Promise of the Mobile Web

  - by Rick Strahl

  High end mobile devices have been with us now for almost 7 years and they have utterly transformed the way we access information. Mobile phones and smartphones that have access to the Internet and host smart applications are in the hands of a large percentage of the population of the world. In many places even very remote, cell phones and even smart phones are a common sight. I’ll never forget when I was in India in 2011 I was up in the Southern Indian mountains riding an elephant out of a tiny local village, with an elephant herder in front riding atop of the elephant in front of us. He was dressed in traditional garb with the loin wrap and head cloth/turban as did quite a few of the locals in this small out of the way and not so touristy village. So we’re slowly trundling along in the forest and he’s lazily using his stick to guide the elephant and… 10 minutes in he pulls out his cell phone from his sash and starts texting. In the middle of texting a huge pig jumps out from the side of the trail and he takes a picture running across our path in the jungle! So yeah, mobile technology is very pervasive and it’s reached into even very buried and unexpected parts of this world. Apps are still King Apps currently rule the roost when it comes to mobile devices and the applications that run on them. If there’s something that you need on your mobile device your first step usually is to look for an app, not use your browser. But native app development remains a pain in the butt, with the requirement to have to support 2 or 3 completely separate platforms. There are solutions that try to bridge that gap. Xamarin is on a tear at the moment, providing their cross-device toolkit to build applications using C#. While Xamarin tools are impressive – and also *very* expensive – they only address part of the development madness that is app development. There are still specific device integration isssues, dealing with the different developer programs, security and certificate setups and all that other noise that surrounds app development. There’s also PhoneGap/Cordova which provides a hybrid solution that involves creating local HTML/CSS/JavaScript based applications, and then packaging them to run in a specialized App container that can run on most mobile device platforms using a WebView interface. This allows for using of HTML technology, but it also still requires all the set up, configuration of APIs, security keys and certification and submission and deployment process just like native applications – you actually lose many of the benefits that  Web based apps bring. The big selling point of Cordova is that you get to use HTML have the ability to build your UI once for all platforms and run across all of them – but the rest of the app process remains in place. Apps can be a big pain to create and manage especially when we are talking about specialized or vertical business applications that aren’t geared at the mainstream market and that don’t fit the ‘store’ model. If you’re building a small intra department application you don’t want to deal with multiple device platforms and certification etc. for various public or corporate app stores. That model is simply not a good fit both from the development and deployment perspective. Even for commercial, big ticket apps, HTML as a UI platform offers many advantages over native, from write-once run-anywhere, to remote maintenance, single point of management and failure to having full control over the application as opposed to have the app store overloads censor you. In a lot of ways Web based HTML/CSS/JavaScript applications have so much potential for building better solutions based on existing Web technologies for the very same reasons a lot of content years ago moved off the desktop to the Web. To me the Web as a mobile platform makes perfect sense, but the reality of today’s Mobile Web unfortunately looks a little different… Where’s the Love for the Mobile Web? Yet here we are in the middle of 2014, nearly 7 years after the first iPhone was released and brought the promise of rich interactive information at your fingertips, and yet we still don’t really have a solid mobile Web platform. I know what you’re thinking: “But we have lots of HTML/JavaScript/CSS features that allows us to build nice mobile interfaces”. I agree to a point – it’s actually quite possible to build nice looking, rich and capable Web UI today. We have media queries to deal with varied display sizes, CSS transforms for smooth animations and transitions, tons of CSS improvements in CSS 3 that facilitate rich layout, a host of APIs geared towards mobile device features and lately even a number of JavaScript framework choices that facilitate development of multi-screen apps in a consistent manner. Personally I’ve been working a lot with AngularJs and heavily modified Bootstrap themes to build mobile first UIs and that’s been working very well to provide highly usable and attractive UI for typical mobile business applications. From the pure UI perspective things actually look very good. Not just about the UI But it’s not just about the UI - it’s also about integration with the mobile device. When it comes to putting all those pieces together into what amounts to a consolidated platform to build mobile Web applications, I think we still have a ways to go… there are a lot of missing pieces to make it all work together and integrate with the device more smoothly, and more importantly to make it work uniformly across the majority of devices. I think there are a number of reasons for this. Slow Standards Adoption HTML standards implementations and ratification has been dreadfully slow, and browser vendors all seem to pick and choose different pieces of the technology they implement. The end result is that we have a capable UI platform that’s missing some of the infrastructure pieces to make it whole on mobile devices. There’s lots of potential but what is lacking that final 10% to build truly compelling mobile applications that can compete favorably with native applications. Some of it is the fragmentation of browsers and the slow evolution of the mobile specific HTML APIs. A host of mobile standards exist but many of the standards are in the early review stage and they have been there stuck for long periods of time and seem to move at a glacial pace. Browser vendors seem even slower to implement them, and for good reason – non-ratified standards mean that implementations may change and vendor implementations tend to be experimental and  likely have to be changed later. Neither Vendors or developers are not keen on changing standards. This is the typical chicken and egg scenario, but without some forward momentum from some party we end up stuck in the mud. It seems that either the standards bodies or the vendors need to carry the torch forward and that doesn’t seem to be happening quickly enough. Mobile Device Integration just isn’t good enough Current standards are not far reaching enough to address a number of the use case scenarios necessary for many mobile applications. While not every application needs to have access to all mobile device features, almost every mobile application could benefit from some integration with other parts of the mobile device platform. Integration with GPS, phone, media, messaging, notifications, linking and contacts system are benefits that are unique to mobile applications and could be widely used, but are mostly (with the exception of GPS) inaccessible for Web based applications today. Unfortunately trying to do most of this today only with a mobile Web browser is a losing battle. Aside from PhoneGap/Cordova’s app centric model with its own custom API accessing mobile device features and the token exception of the GeoLocation API, most device integration features are not widely supported by the current crop of mobile browsers. For example there’s no usable messaging API that allows access to SMS or contacts from HTML. Even obvious components like the Media Capture API are only implemented partially by mobile devices. There are alternatives and workarounds for some of these interfaces by using browser specific code, but that’s might ugly and something that I thought we were trying to leave behind with newer browser standards. But it’s not quite working out that way. It’s utterly perplexing to me that mobile standards like Media Capture and Streams, Media Gallery Access, Responsive Images, Messaging API, Contacts Manager API have only minimal or no traction at all today. Keep in mind we’ve had mobile browsers for nearly 7 years now, and yet we still have to think about how to get access to an image from the image gallery or the camera on some devices? Heck Windows Phone IE Mobile just gained the ability to upload images recently in the Windows 8.1 Update – that’s feature that HTML has had for 20 years! These are simple concepts and common problems that should have been solved a long time ago. It’s extremely frustrating to see build 90% of a mobile Web app with relative ease and then hit a brick wall for the remaining 10%, which often can be show stoppers. The remaining 10% have to do with platform integration, browser differences and working around the limitations that browsers and ‘pinned’ applications impose on HTML applications. The maddening part is that these limitations seem arbitrary as they could easily work on all mobile platforms. For example, SMS has a URL Moniker interface that sort of works on Android, works badly with iOS (only works if the address is already in the contact list) and not at all on Windows Phone. There’s no reason this shouldn’t work universally using the same interface – after all all phones have supported SMS since before the year 2000! But, it doesn’t have to be this way Change can happen very quickly. Take the GeoLocation API for example. Geolocation has taken off at the very beginning of the mobile device era and today it works well, provides the necessary security (a big concern for many mobile APIs), and is supported by just about all major mobile and even desktop browsers today. It handles security concerns via prompts to avoid unwanted access which is a model that would work for most other device APIs in a similar fashion. One time approval and occasional re-approval if code changes or caches expire. Simple and only slightly intrusive. It all works well, even though GeoLocation actually has some physical limitations, such as representing the current location when no GPS device is present. Yet this is a solved problem, where other APIs that are conceptually much simpler to implement have failed to gain any traction at all. Technically none of these APIs should be a problem to implement, but it appears that the momentum is just not there. Inadequate Web Application Linking and Activation Another important piece of the puzzle missing is the integration of HTML based Web applications. Today HTML based applications are not first class citizens on mobile operating systems. When talking about HTML based content there’s a big difference between content and applications. Content is great for search engine discovery and plain browser usage. Content is usually accessed intermittently and permanent linking is not so critical for this type of content.  But applications have different needs. Applications need to be started up quickly and must be easily switchable to support a multi-tasking user workflow. Therefore, it’s pretty crucial that mobile Web apps are integrated into the underlying mobile OS and work with the standard task management features. Unfortunately this integration is not as smooth as it should be. It starts with actually trying to find mobile Web applications, to ‘installing’ them onto a phone in an easily accessible manner in a prominent position. The experience of discovering a Mobile Web ‘App’ and making it sticky is by no means as easy or satisfying. Today the way you’d go about this is: Open the browser Search for a Web Site in the browser with your search engine of choice Hope that you find the right site Hope that you actually find a site that works for your mobile device Click on the link and run the app in a fully chrome’d browser instance (read tiny surface area) Pin the app to the home screen (with all the limitations outline above) Hope you pointed at the right URL when you pinned Even for you and me as developers, there are a few steps in there that are painful and annoying, but think about the average user. First figuring out how to search for a specific site or URL? And then pinning the app and hopefully from the right location? You’ve probably lost more than half of your audience at that point. This experience sucks. For developers too this process is painful since app developers can’t control the shortcut creation directly. This problem often gets solved by crazy coding schemes, with annoying pop-ups that try to get people to create shortcuts via fancy animations that are both annoying and add overhead to each and every application that implements this sort of thing differently. And that’s not the end of it - getting the link onto the home screen with an application icon varies quite a bit between browsers. Apple’s non-standard meta tags are prominent and they work with iOS and Android (only more recent versions), but not on Windows Phone. Windows Phone instead requires you to create an actual screen or rather a partial screen be captured for a shortcut in the tile manager. Who had that brilliant idea I wonder? Surprisingly Chrome on recent Android versions seems to actually get it right – icons use pngs, pinning is easy and pinned applications properly behave like standalone apps and retain the browser’s active page state and content. Each of the platforms has a different way to specify icons (WP doesn’t allow you to use an icon image at all), and the most widely used interface in use today is a bunch of Apple specific meta tags that other browsers choose to support. The question is: Why is there no standard implementation for installing shortcuts across mobile platforms using an official format rather than a proprietary one? Then there’s iOS and the crazy way it treats home screen linked URLs using a crazy hybrid format that is neither as capable as a Web app running in Safari nor a WebView hosted application. Moving off the Web ‘app’ link when switching to another app actually causes the browser and preview it to ‘blank out’ the Web application in the Task View (see screenshot on the right). Then, when the ‘app’ is reactivated it ends up completely restarting the browser with the original link. This is crazy behavior that you can’t easily work around. In some situations you might be able to store the application state and restore it using LocalStorage, but for many scenarios that involve complex data sources (like say Google Maps) that’s not a possibility. The only reason for this screwed up behavior I can think of is that it is deliberate to make Web apps a pain in the butt to use and forcing users trough the App Store/PhoneGap/Cordova route. App linking and management is a very basic problem – something that we essentially have solved in every desktop browser – yet on mobile devices where it arguably matters a lot more to have easy access to web content we have to jump through hoops to have even a remotely decent linking/activation experience across browsers. Where’s the Money? It’s not surprising that device home screen integration and Mobile Web support in general is in such dismal shape – the mobile OS vendors benefit financially from App store sales and have little to gain from Web based applications that bypass the App store and the cash cow that it presents. On top of that, platform specific vendor lock-in of both end users and developers who have invested in hardware, apps and consumables is something that mobile platform vendors actually aspire to. Web based interfaces that are cross-platform are the anti-thesis of that and so again it’s no surprise that the mobile Web is on a struggling path. But – that may be changing. More and more we’re seeing operations shifting to services that are subscription based or otherwise collect money for usage, and that may drive more progress into the Web direction in the end . Nothing like the almighty dollar to drive innovation forward. Do we need a Mobile Web App Store? As much as I dislike moderated experiences in today’s massive App Stores, they do at least provide one single place to look for apps for your device. I think we could really use some sort of registry, that could provide something akin to an app store for mobile Web apps, to make it easier to actually find mobile applications. This could take the form of a specialized search engine, or maybe a more formal store/registry like structure. Something like apt-get/chocolatey for Web apps. It could be curated and provide at least some feedback and reviews that might help with the integrity of applications. Coupled to that could be a native application on each platform that would allow searching and browsing of the registry and then also handle installation in the form of providing the home screen linking, plus maybe an initial security configuration that determines what features are allowed access to for the app. I’m not holding my breath. In order for this sort of thing to take off and gain widespread appeal, a lot of coordination would be required. And in order to get enough traction it would have to come from a well known entity – a mobile Web app store from a no name source is unlikely to gain high enough usage numbers to make a difference. In a way this would eliminate some of the freedom of the Web, but of course this would also be an optional search path in addition to the standard open Web search mechanisms to find and access content today. Security Security is a big deal, and one of the perceived reasons why so many IT professionals appear to be willing to go back to the walled garden of deployed apps is that Apps are perceived as safe due to the official review and curation of the App stores. Curated stores are supposed to protect you from malware, illegal and misleading content. It doesn’t always work out that way and all the major vendors have had issues with security and the review process at some time or another. Security is critical, but I also think that Web applications in general pose less of a security threat than native applications, by nature of the sandboxed browser and JavaScript environments. Web applications run externally completely and in the HTML and JavaScript sandboxes, with only a very few controlled APIs allowing access to device specific features. And as discussed earlier – security for any device interaction can be granted the same for mobile applications through a Web browser, as they can for native applications either via explicit policies loaded from the Web, or via prompting as GeoLocation does today. Security is important, but it’s certainly solvable problem for Web applications even those that need to access device hardware. Security shouldn’t be a reason for Web apps to be an equal player in mobile applications. Apps are winning, but haven’t we been here before? So now we’re finding ourselves back in an era of installed app, rather than Web based and managed apps. Only it’s even worse today than with Desktop applications, in that the apps are going through a gatekeeper that charges a toll and censors what you can and can’t do in your apps. Frankly it’s a mystery to me why anybody would buy into this model and why it’s lasted this long when we’ve already been through this process. It’s crazy… It’s really a shame that this regression is happening. We have the technology to make mobile Web apps much more prominent, but yet we’re basically held back by what seems little more than bureaucracy, partisan bickering and self interest of the major parties involved. Back in the day of the desktop it was Internet Explorer’s 98+%  market shareholding back the Web from improvements for many years – now it’s the combined mobile OS market in control of the mobile browsers. If mobile Web apps were allowed to be treated the same as native apps with simple ways to install and run them consistently and persistently, that would go a long way to making mobile applications much more usable and seriously viable alternatives to native apps. But as it is mobile apps have a severe disadvantage in placement and operation. There are a few bright spots in all of this. Mozilla’s FireFoxOs is embracing the Web for it’s mobile OS by essentially building every app out of HTML and JavaScript based content. It supports both packaged and certified package modes (that can be put into the app store), and Open Web apps that are loaded and run completely off the Web and can also cache locally for offline operation using a manifest. Open Web apps are treated as full class citizens in FireFoxOS and run using the same mechanism as installed apps. Unfortunately FireFoxOs is getting a slow start with minimal device support and specifically targeting the low end market. We can hope that this approach will change and catch on with other vendors, but that’s also an uphill battle given the conflict of interest with platform lock in that it represents. Recent versions of Android also seem to be working reasonably well with mobile application integration onto the desktop and activation out of the box. Although it still uses the Apple meta tags to find icons and behavior settings, everything at least works as you would expect – icons to the desktop on pinning, WebView based full screen activation, and reliable application persistence as the browser/app is treated like a real application. Hopefully iOS will at some point provide this same level of rudimentary Web app support. What’s also interesting to me is that Microsoft hasn’t picked up on the obvious need for a solid Web App platform. Being a distant third in the mobile OS war, Microsoft certainly has nothing to lose and everything to gain by using fresh ideas and expanding into areas that the other major vendors are neglecting. But instead Microsoft is trying to beat the market leaders at their own game, fighting on their adversary’s terms instead of taking a new tack. Providing a kick ass mobile Web platform that takes the lead on some of the proposed mobile APIs would be something positive that Microsoft could do to improve its miserable position in the mobile device market. Where are we at with Mobile Web? It sure sounds like I’m really down on the Mobile Web, right? I’ve built a number of mobile apps in the last year and while overall result and response has been very positive to what we were able to accomplish in terms of UI, getting that final 10% that required device integration dialed was an absolute nightmare on every single one of them. Big compromises had to be made and some features were left out or had to be modified for some devices. In two cases we opted to go the Cordova route in order to get the integration we needed, along with the extra pain involved in that process. Unless you’re not integrating with device features and you don’t care deeply about a smooth integration with the mobile desktop, mobile Web development is fraught with frustration. So, yes I’m frustrated! But it’s not for lack of wanting the mobile Web to succeed. I am still a firm believer that we will eventually arrive a much more functional mobile Web platform that allows access to the most common device features in a sensible way. It wouldn't be difficult for device platform vendors to make Web based applications first class citizens on mobile devices. But unfortunately it looks like it will still be some time before this happens. So, what’s your experience building mobile Web apps? Are you finding similar issues? Just giving up on raw Web applications and building PhoneGap apps instead? Completely skipping the Web and going native? Leave a comment for discussion.

• Add New Features to WMP with Windows Media Player Plus

  - by DigitalGeekery

  Do you use Windows Media Player 11 or 12 as your default media player? Today, we’re going to show you how to add some handy new features and enhancements with the Windows Media Player Plus third party plug-in. Installation and Setup Download and install Media Player Plus! (link below). You’ll need to close out of Windows Media Player before you begin or you’ll receive the message below. The next time you open Media Player you’ll be presented with the Media Player Plus settings window. Some of the settings will be enabled by default, such as the Find as you type feature. Using Media Player Plus! Find as you type allows you to start typing a search term from anywhere in Media Player without having to be in the Search box. The search term will automatically fill in the search box and display the results.   You’ll also see Disable group headers in the Library Pane.   This setting will display library items in a continuous list similar to the functionality of Windows Media Player 10. Under User Interface you can enable displaying the currently playing artist and title in the title bar. This is enabled by default.   The Context Menu page allows you to enable context menu enhancements. The File menu enhancement allows you to add the Windows Context menu to Media Player on the library pane, list pane, or both. Right click on a Title, select File, and you’ll see the Windows Context Menu. Right-click on a title and select Tag Editor Plus. Tag Editor Plus allows you to quickly edit media tags.   The Advanced tab displays a number of tags that Media Player usually doesn’t show. Only the tags with the notepad and pencil icon are editable.   The Restore Plug-ins page allows you to configure which plug-ins should be automatically restored after a Media Player crash. The Restore Media at Startup page allows you to configure Media Player to resume playing the last playlist, track, and even whether it was playing or paused at the time the application was closed. So, if you close out in the middle of a song, it will begin playing from that point the next time you open Media Player. You can also set Media Player to rewind a certain number of seconds from where you left off. This is especially useful if you are in the middle of watching a movie. There’s also the option to have your currently playing song sent to Windows Live Messenger. You can access the settings at any time by going to Tools, Plug-in properties, and selecting Windows Media Player Plus. Windows Media Plus is a nice little free plug-in for WMP 11 and 12 that brings a lot of additional functionality to Windows Media Player. If you use Media Player 11 or WMP 12 in Windows 7 as your main player, you might want to give this a try. Download Windows Media Player Plus!

• How To Disable Control Panel in Windows 7

  - by Mysticgeek

  If you have a shared computer that your family and friends can access, you might not want them to mess around in the Control Panel, and luckily with a simple tweak you can disable it. Disable Control Panel with Group Policy Note: This process uses Local Group Policy Editor which is not available in Home versions of Windows 7. Skip down below for the registry hack version that works on Home editions as well. First type gpedit.msc into the Search box in the Start menu and hit Enter. When Local Group Policy Editor opens, navigate to User Configuration \ Administrative Templates then select Control Panel in the left Column. In the right column double-click on Prohibit access to the Control Panel. In the next window, select Enable, click OK, then close out of Local Group Policy Editor. After the Control Panel is disabled, you’ll notice it’s no longer listed in the Start Menu. If the user tries to type Control Panel into the Search box in the Start menu, they will get the following message indicating it’s restricted. Disable Control Panel with a Registry Tweak You can also tweak the Registry to disable Control Panel. This will work with all versions of Windows 7, Vista, and XP. Making changes in the Registry is not recommended for beginners and you should create a Restore Point, or backup the Registry before making any changes. Type regedit into the Search box in the Start menu and hit Enter. In Registry Editor navigate to HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer. Then right-click in the right pane and create a new DWORD (32-bit) Value. Name the value NoControlPanel. Then right-click on the new Value and click Modify…   In the Value data field change the value to “1” then click OK. Close out of Registry Editor and restart the machine to complete the process. When you get back from reboot, you’ll notice Control Panel is no longer listed in the Start menu. If a user tries to access it by typing Control Panel into the Search box in the Start menu… They will get the following message indicating it is restricted, just like if you were to disable it via Group Policy. If you want to re-enable the Control Panel, go back into the Registry and change the NoControlPanel value back to “0” then reboot the computer. This comes in handy if you have inexperienced users working on your machine and don’t want them messing with Control Panel settings.

• The Beginner’s Guide to Greasemonkey User Scripts in Firefox

  - by Asian Angel

  Everybody knows that Firefox has add-ons for virtually everything, but if you don’t want to bloat your installation you’ve always got the option of Greasemonkey scripts instead. Here’s a quick primer on how to use them. Getting Started with User Scripts Once you have Greasemonkey installed, managing the extension is really easy. Left click on the status bar icon to turn the extension on/off and right click to access the context menu shown here. Whether you use the Options button in the Add-ons Manager Window or the context menu shown above, both will bring up the Manage User Scripts dialog. At the moment you have a nice clean slate to work with… time to get some scripts added in. The majority of user scripts can be found at two different sites, the first being appropriately named userscripts.org, and you can either browse by tag or search for a script. As you can see here your search for a particular type of script can be quickly narrowed down based on category. There is definitely a lot to choose from. For our example we focused on the “textarea” tag. There were 62 scripts available but we quickly found what we were looking for on the first page. Installing, Managing, & Using Your Scripts When you find a script that you want to install visit the script’s homepage and click on the “Install” button. Note: Link for this script provided below. Once you have clicked on the Install button, Greasemonkey will open up the following installation window. You will be able to view: A summary of what the script does A list of websites that the script is supposed to function on (our example is set for all) View the script source if desired Make a final decision on whether to install the script or cancel the process Right-clicking on our status bar icon shows our new script listed and active. Reopening the Manage User Scripts window shows: Our new script listed in the column on the left The websites/pages included An option to disable the script (can also be done in the context menu) The ability to edit the script The ability to uninstall the script If you choose to edit the script you will be asked to browse for and select a default text editor of your choice (first time only). Once you have selected a text editor you can make any changes desired to the script. We decided to test our new user script on the site. Going to the comment box at the bottom we could easily resize the window as desired. The Comment box definitely got a lot bigger. Conclusion If you prefer to keep the number of extensions to a minimum in your Firefox installation then Greasemonkey and the Userscripts website can easily provide that extra functionality without the bloat. For added auto website script detection goodness see our article on Greasefire. Note: See our article here for specialized How-To Geek User Style Scripts that can be added to Greasemonkey.

• Error Handling Examples(C#)

  “The purpose of reviewing the Error Handling code is to assure that the application fails safely under all possible error conditions, expected and unexpected. No sensitive information is presented to the user when an error occurs.” (OWASP, 2011) No Error Handling The absence of error handling is still a form of error handling. Based on the code in Figure 1, if an error occurred and was not handled within either the ReadXml or BuildRequest methods the error would bubble up to the Search method. Since this method does not handle any acceptations the error will then bubble up the stack trace. If this continues and the error is not handled within the application then the environment in which the application is running will notify the user running the application that an error occurred based on what type of application. Figure 1: No Error Handling public DataSet Search(string searchTerm, int resultCount) { DataSet dt = new DataSet(); dt.ReadXml(BuildRequest(searchTerm, resultCount)); return dt; } Generic Error Handling One simple way to add error handling is to catch all errors by default. If you examine the code in Figure 2, you will see a try-catch block. On April 6th 2010 Louis Lazaris clearly describes a Try Catch statement by defining both the Try and Catch aspects of the statement. “The try portion is where you would put any code that might throw an error. In other words, all significant code should go in the try section. The catch section will also hold code, but that section is not vital to the running of the application. So, if you removed the try-catch statement altogether, the section of code inside the try part would still be the same, but all the code inside the catch would be removed.” (Lazaris, 2010) He also states that all errors that occur in the try section cause it to stops the execution of the try section and redirects all execution to the catch section. The catch section receives an object containing information about the error that occurred so that they system can gracefully handle the error properly. When errors occur they commonly log them in some form. This form could be an email, database entry, web service call, log file, or just an error massage displayed to the user.  Depending on the error sometimes applications can recover, while others force an application to close. Figure 2: Generic Error Handling public DataSet Search(string searchTerm, int resultCount) { DataSet dt = new DataSet(); try { dt.ReadXml(BuildRequest(searchTerm, resultCount)); } catch (Exception ex) { // Handle all Exceptions } return dt; } Error Specific Error Handling Like the Generic Error Handling, Error Specific error handling allows for the catching of specific known errors that may occur. For example wrapping a try catch statement around a soap web service call would allow the application to handle any error that was generated by the soap web service. Now, if the systems wanted to send a message to the web service provider every time a soap error occurred but did not want to notify them if any other type of error occurred like a network time out issue. This would be varying tedious to accomplish using the General Error Handling methodology. This brings us to the use case for using the Error Specific error handling methodology.  The Error Specific Error handling methodology allows for the TryCatch statement to catch various types of errors depending on the type of error that occurred. In Figure 3, the code attempts to handle DataException differently compared to how it potentially handles all other errors. This allows for specific error handling for each type of known error, and still allows for error handling of any unknown error that my occur during the execution of the TryCatch statement. Figure 5: Error Specific Error Handling public DataSet Search(string searchTerm, int resultCount) { DataSet dt = new DataSet(); try { dt.ReadXml(BuildRequest(searchTerm, resultCount)); } catch (TimeoutException ex) { // Handle Timeout TimeoutException Only } catch (Exception) { // Handle all Exceptions } return dt; }

• Understanding Collabnet&rsquo;s LDAP binding

  - by Robert May

  We want to use both subversion usernames and passwords as well as Active Directory for our authentication on our Collabnet subversion server. This has proven to be more of a challenge than we thought, mostly because Collabnet’s documentation is pretty poor. To supplement that documentation, I add my own. The first thing to understand is that the attribute that you specify in the LDAP Login Attribute ONLY applies to lookups done for the user.  It does NOT apply to the LDAP Bind DN field.  Second, know that the debug logs (error is the one you want) don’t give you debug information for the bind DN, just the login attempts.  Third, by default, Active Directory does not allow anonymous binds, so you MUST put in a user that has the authority to query the Active Directory ldap. Because of these items, the values to set in those fields can be somewhat confusing.  You’ll want to have ADSI Edit handy (I also used ldp, which is installed by default on server 2008), since ADSI Edit can help you find stuff in your active directory.  Be careful, you can also break stuff. Here’s what should go into those fields. LDAP Security Level:  Should be set to None LDAP Server Host:  Should be set to the full name of a domain controller in your domain.  For example, dc.mydomain.com LDAP Server Port:  Should be set to 3268.  The default port of 389 will only query that specific server, not the global catalog.  By setting it to 3268, the global catalog will be queried, which is probably what you want. LDAP Base DN:  Should be set to the location where you want the search for users to begin.  By default, the search scope is set to sub, so all child organizational units below this setting will be searched.  In my case, I had created an OU specifically for users for group policies.  My value ended up being:  OU=MyOu,DC=domain,DC=org.   However, if you’re pointing it to the default Users folder, you may end up with something like CN=Users,DC=domain,DC=org (or com or whatever).  Again, use ADSI edit and use the Distinguished Name that it shows. LDAP Bind DN:  This needs to be the Distinguished Name of the user that you’re going to use for binding (i.e. the user you’ll be impersonating) for doing queries.  In my case, it ended up being CN=svn svn,OU=MyOu,DC=domain,DC=org.  Why the double svn, you might ask?  That’s because the first and last name fields are set to svn and by default, the distinguished name is the first and last name fields!  That’s important.  Its NOT the username or account name!  Again, use ADSI edit, browse to the username you want to use, right click and select properties, and then search the attributes for the Distinguished Name.  Once you’ve found that, select it and click View and you can copy and paste that into this field. LDAP Bind Password:  This is the password for the account in the Bind DN LDAP login Attribute: sAMAccountName.  If you leave this blank, uid is used, which may not even be set.  This tells it to use the Account Name field that’s defined under the account tab for users in Active Directory Users and Computers.  Note that this attribute DOES NOT APPLY to the LDAP Bind DN.  You must use the full distinguished name of the bind DN.  This attribute allows users to type their username and password for authentication, rather than typing their distinguished name, which they probably don’t know. LDAP Search Scope:  Probably should stay at sub, but could be different depending on your situation. LDAP Filter:  I left mine blank, but you could provide one to limit what you want to see.  LDP would be helpful for determining what this is. LDAP Server Certificate Verification:  I left it checked, but didn’t try it without it being checked. Hopefully, this will save some others pain when trying to get Collabnet setup.

• 6 Prominent Features of New GMail User Interface

  - by Gopinath

  GMail’s user interface has got a big make over today and the new user interface is available to everyone. We can switch to the new user interface by click on “Switch to the new look” link available at the bottom right of GMail (If you are on IE 6 or similar type of bad browsers, you will not see the option!). I switched to the new user interface as soon I noticed the link and played with it for sometime. In this post I want to share the prominent features of all new GMail interface. 1. All New Conversations Interface GMail’s threaded conversations is a game changing feature when it was first introduced by Google. For  a long time we have not seen much updates to the threaded conversation views. In the new GMail interface, threaded conversation sports a great new look – conversations are always visible in a horizontal fashion as opposed to stack interface of earlier version. When you open a conversation, you get a quick glance of individual thread without expanding the thread. Readability is improved a lot now.  Check image after the break 2. Sender Profile Photos In Email Threads Did you observe the above screenshot of conversations view? It has profile images of the participants in the thread. Identifying person of a thread is much more easy. 3. Advanced Search Box Search is the heart of Google’s business and it’s their flagship technology. GMail’s search interface is enhanced to let you quickly find the required e-mails. Also you can create mail filters from the search box without leaving the screen or opening up a new popup. 4. Gmail Automatically Resizing To Fit Multiple Devices There is no doubt that this is post PC era where people started using more of tablets and big screen smartphones than ever. The new user interface of GMail automatically resizes itself to fit the size of screen seamlessly. 5. HD Images For Your Themes, Sourced from iStockphoto Are you bored with minimalistic GMail interface and the few flashy themes? Here comes GMail HD themes backed by stock photographs sourced from iStockPhoto website. If you have a widescreen HD monitor then decorate your inbox with beautiful themes. 6. Resize Labels & Chat Panels Now you got a splitter between Labels & Chat panel that lets resize their height as you prefer. Also Label panel auto expands its height when you mouse over to show you hidden labels if any. Video – overview of new GMail features This article titled,6 Prominent Features of New GMail User Interface, was originally published at Tech Dreams.

• How Can I Start an Incognito/Private Browsing Window from a Shortcut?

  - by Jason Fitzpatrick

  Sometimes you just want to pop the browser open for a quick web search without reloading all your saved tabs; read on as we show a fellow reader how to make a quick private-browsing shortcut. Dear How-To Geek, I came up with a solution to my problem, but I need your help implementing it. I typically have a ton of tabs open in my web browser and, when I need to free up system resources when gaming or using a resource intense application, I shut down the web browser. The problem arises when I find myself needing to do quick web search while the browser is shut down. I don’t want to open it up, load all the tabs, and waste the resources in doing so all for a quick Google search. The perfect solution, it would seem, is to open up one of Chrome’s Incognito windows: it loads separate, it won’t open up all the old tabs, and it’s perfect for a quick Google search. Is there a way to launch Chrome with a single Incognito window open without having to open the browser in the normal mode (and load the bazillion tabs I have sitting there)? Sincerely, Tab Crazy That’s a rather clever work around to your problem. Since you’ve already done the hard work of figuring out the solution you need, we’re more than happy to help you across the finish line. The magic you seek is available via what are known as “command line options” which allow you to add additional parameters and switches onto a command.   By appending the command the Chrome shortcut uses, we can easily tell it to launch in Incognito mode. (And, for other readers following along at home, we can do the same thing with other browsers like Firefox). First, let’s look at Chrome’s default shortcut: If you right click on it and select the properties menu, you’ll see where the shortcut points: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" If you run that shortcut, you’ll open up normal browsing mode in Chrome and your saved tabs will all load. What we need to do is use the command line switches available for Chrome and tell it that we want it to launch an Incognito window instead. Doing so is as simple as appending the end of the “Target” box’s command line entry with -incognito, like so: "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" -incognito We’d also recommend changing the icon to it’s easy to tell the default Chrome shortcut apart from your new Incognito shortcut. When you’re done, make sure to hit OK/Apply at the button to save the changes. You can recreate the same private-browsing-shortcut effect with other major web browsers too. Repeat shortcut editing steps we highlighted above, but change out the -incognito with -private (for Firefox and Internet Explorer) and -newprivatetab (for Opera). With just a simple command line switch applied, you can now launch a lightweight single browser window for those quick web searches without having to stop your game and load up all your saved tabs.

• Grid pathfinding with a lot of entities

  - by Vee

  I'd like to explain this problem with a screenshot from a released game, DROD: Gunthro's Epic Blunder, by Caravel Games. The game is turn-based and tile-based. I'm trying to create something very similar (a clone of the game), and I've got most of the fundamentals done, but I'm having trouble implementing pathfinding. Look at the screenshot. The guys in yellow are friendly, and want to kill the roaches. Every turn, every guy in yellow pathfinds to the closest roach, and every roach pathfinds to the closest guy in yellow. By closest I mean the target with the shortest path, not a simple distance calculation. All of this without any kind of slowdown when loading the level or when passing turns. And all of the entities change position every turn. Also (not shown in screenshot), there can be doors that open and close and change the level's layout. Impressive. I've tried implementing pathfinding in my clone. First attempt was making every roach find a path to a yellow guy every turn, using a breadth-first search algorithm. Obviously incredibly slow with more than a single roach, and would get exponentially slower with more than a single yellow guy. Second attempt was mas making every yellow guy generate a pathmap (still breadth-first search) every time he moved. Worked perfectly with multiple roaches and a single yellow guy, but adding more yellow guys made the game slow and unplayable. Last attempt was implementing JPS (jump point search). Every entity would individually calculate a path to its target. Fast, but with a limited number of entities. Having less than half the entities in the screenshot would make the game slow. And also, I had to get the "closest" enemy by calculating distance, not shortest path. I've asked on the DROD forums how they did it, and a user replied that it was breadth-first search. The game is open source, and I took a look at the source code, but it's C++ (I'm using C#) and I found it confusing. I don't know how to do it. Every approach I tried isn't good enough. And I believe that DROD generates global pathmaps, somehow, but I can't understand how every entity find the best individual path to other entities that move every turn. What's the trick? This is a reply I just got on the DROD forums: Without having looked at the code I'd wager it's two (or so) pathmaps for the whole room: One to the nearest enemy, and one to the nearest friendly for every tile. There's no need to make a separate pathmap for every entity when the overall goal is "move towards nearest enemy/friendly"... just mark every tile with the number of moves it takes to the nearest target and have the entity chose the move that takes it to the tile with the lowest number. To be honest, I don't understand it that well.

• Stale statistics on a newly created temporary table in a stored procedure can lead to poor performance

  - by sqlworkshops

  When you create a temporary table you expect a new table with no past history (statistics based on past existence), this is not true if you have less than 6 updates to the temporary table. This might lead to poor performance of queries which are sensitive to the content of temporary tables.I was optimizing SQL Server Performance at one of my customers who provides search functionality on their website. They use stored procedure with temporary table for the search. The performance of the search depended on who searched what in the past, option (recompile) by itself had no effect. Sometimes a simple search led to timeout because of non-optimal plan usage due to this behavior. This is not a plan caching issue rather temporary table statistics caching issue, which was part of the temporary object caching feature that was introduced in SQL Server 2005 and is also present in SQL Server 2008 and SQL Server 2012. In this customer case we implemented a workaround to avoid this issue (see below for example for workarounds).When temporary tables are cached, the statistics are not newly created rather cached from the past and updated based on automatic update statistics threshold. Caching temporary tables/objects is good for performance, but caching stale statistics from the past is not optimal.We can work around this issue by disabling temporary table caching by explicitly executing a DDL statement on the temporary table. One possibility is to execute an alter table statement, but this can lead to duplicate constraint name error on concurrent stored procedure execution. The other way to work around this is to create an index.I think there might be many customers in such a situation without knowing that stale statistics are being cached along with temporary table leading to poor performance.Ideal solution is to have more aggressive statistics update when the temporary table has less number of rows when temporary table caching is used. I will open a connect item to report this issue.Meanwhile you can mitigate the issue by creating an index on the temporary table. You can monitor active temporary tables using Windows Server Performance Monitor counter: SQL Server: General Statistics->Active Temp Tables. The script to understand the issue and the workaround is listed below:set nocount onset statistics time offset statistics io offdrop table tab7gocreate table tab7 (c1 int primary key clustered, c2 int, c3 char(200))gocreate index test on tab7(c2, c1, c3)gobegin trandeclare @i intset @i = 1while @i <= 50000begininsert into tab7 values (@i, 1, ‘a’)set @i = @i + 1endcommit trangoinsert into tab7 values (50001, 1, ‘a’)gocheckpointgodrop proc test_slowgocreate proc test_slow @i intasbegindeclare @j intcreate table #temp1 (c1 int primary key)insert into #temp1 (c1) select @iselect @j = t7.c1 from tab7 t7 inner join #temp1 t on (t7.c2 = t.c1)endgodbcc dropcleanbuffersset statistics time onset statistics io ongo–high reads as expected for parameter ’1'exec test_slow 1godbcc dropcleanbuffersgo–high reads that are not expected for parameter ’2'exec test_slow 2godrop proc test_with_recompilegocreate proc test_with_recompile @i intasbegindeclare @j intcreate table #temp1 (c1 int primary key)insert into #temp1 (c1) select @iselect @j = t7.c1 from tab7 t7 inner join #temp1 t on (t7.c2 = t.c1)option (recompile)endgodbcc dropcleanbuffersset statistics time onset statistics io ongo–high reads as expected for parameter ’1'exec test_with_recompile 1godbcc dropcleanbuffersgo–high reads that are not expected for parameter ’2'–low reads on 3rd execution as expected for parameter ’2'exec test_with_recompile 2godrop proc test_with_alter_table_recompilegocreate proc test_with_alter_table_recompile @i intasbegindeclare @j intcreate table #temp1 (c1 int primary key)–to avoid caching of temporary tables one can create a constraint–but this might lead to duplicate constraint name error on concurrent usagealter table #temp1 add constraint test123 unique(c1)insert into #temp1 (c1) select @iselect @j = t7.c1 from tab7 t7 inner join #temp1 t on (t7.c2 = t.c1)option (recompile)endgodbcc dropcleanbuffersset statistics time onset statistics io ongo–high reads as expected for parameter ’1'exec test_with_alter_table_recompile 1godbcc dropcleanbuffersgo–low reads as expected for parameter ’2'exec test_with_alter_table_recompile 2godrop proc test_with_index_recompilegocreate proc test_with_index_recompile @i intasbegindeclare @j intcreate table #temp1 (c1 int primary key)–to avoid caching of temporary tables one can create an indexcreate index test on #temp1(c1)insert into #temp1 (c1) select @iselect @j = t7.c1 from tab7 t7 inner join #temp1 t on (t7.c2 = t.c1)option (recompile)endgoset statistics time onset statistics io ondbcc dropcleanbuffersgo–high reads as expected for parameter ’1'exec test_with_index_recompile 1godbcc dropcleanbuffersgo–low reads as expected for parameter ’2'exec test_with_index_recompile 2go

• Web Service Example - Part 3: Asynchronous

  - by Denis T

  In this edition of the ADF Mobile blog we'll tackle part 3 of our Web Service examples.  In this posting we'll take a look at firing the web service asynchronously and then filling in the UI when it completes.  This can be useful when you have data on the device in a local store and want to show that to the user while the application uses lazy loading from a web service to load more data. Getting the sample code: Just click here to download a zip of the entire project.  You can unzip it and load it into JDeveloper and deploy it either to iOS or Android.  Please follow the previous blog posts if you need help getting JDeveloper or ADF Mobile installed.  Note: This is a different workspace than WS-Part2 What's different? In this example, when you click the Search button on the Forecast By Zip option, now it takes you directly to the results page, which is initially blank.  When the web service returns a second or two later the data pops into the UI.  If you go back to the search page and hit Search it will again clear the results and invoke the web service asynchronously.  This isn't really that useful for this particular example but it shows an important technique that can be used for other use cases. How it was done 1)  First we created a new class, ForecastWorker, that implements the Runnable interface.  This is used as our worker class that we create an instance of and pass to a new thread that we create when the Search button is pressed inside the retrieveForecast actionListener handler.  Once the thread is started, the retrieveForecast returns immediately.  2)  The rest of the code that we had previously in the retrieveForecast method has now been moved to the retrieveForecastAsync.  Note that we've also added synchronized specifiers on both these methods so they are protected from re-entrancy. 3)  The run method of the ForecastWorker class then calls the retrieveForecastAsync method.  This executes the web service code that we had previously, but now on a separate thread so the UI is not locked.  If we had already shown data on the screen it would have appeared before this was invoked.  Note that you do not see a loading indicator either because this is on a separate thread and nothing is blocked. 4)  The last but very important aspect of this method is that once we update data in the collections from the data we retrieve from the web service, we call AdfmfJavaUtilities.flushDataChangeEvents().   We need this because as data is updated in the background thread, those data change events are not propagated to the main thread until you explicitly flush them.  As soon as you do this, the UI will get updated if any changes have been queued. Summary of Fundamental Changes In This Application The most fundamental change is that we are invoking and handling our web services in a background thread and updating the UI when the data returns.  This allows an application to provide a better user experience in many cases because data that is already available locally is displayed while lengthy queries or web service calls can be done in the background and the UI updated when they return.  There are many different use cases for background threads and this is just one example of optimizing the user experience and generating a better mobile application.

• Multidimensional multiple-choice knapsack problem: find a feasible solution

  - by Onheiron

  My assignment is to use local search heuristics to solve the Multidimensional multiple-choice knapsack problem, but to do so I first need to find a feasible solution to start with. Here is an example problem with what I tried so far. Problem R1 R2 R3 RESOUCES : 8 8 8 GROUPS: G1: 11.0 3 2 2 12.0 1 1 3 G2: 20.0 1 1 3 5.0 2 3 2 G3: 10.0 2 2 3 30.0 1 1 3 Sorting strategies To find a starting feasible solution for my local search I decided to ignore maximization of gains and just try to fit the resources requirements. I decided to sort the choices (strategies) in each group by comparing their "distance" from the multidimensional space origin, thus calculating SQRT(R1^2 + R2^2 + ... + RN^2). I felt like this was a keen solution as it somehow privileged those choices with resouce usages closer to each other (e.g. R1:2 R2:2 R3:2 < R1:1 R2:2 R3:3) even if the total sum is the same. Doing so and selecting the best choice from each group proved sufficent to find a feasible solution for many[30] different benchmark problems, but of course I knew it was just luck. So I came up with the problem presented above which sorts like this: R1 R2 R3 RESOUCES : 8 8 8 GROUPS: G1: 12.0 1 1 3 < select this 11.0 3 2 2 G2: 20.0 1 1 3 < select this 5.0 2 3 2 G3: 30.0 1 1 3 < select this 10.0 2 2 3 And it is not feasible because the resources consmption is R1:3, R2:3, R3:9. The easy solution is to pick one of the second best choices in group 1 or 2, so I'll need some kind of iteration (local search[?]) to find the starting feasible solution for my local search solution. Here are the options I came up with Option 1: iterate choices I tried to find a way to iterate all the choices with a specific order, something like G1 G2 G3 1 1 1 2 1 1 1 2 1 1 1 2 2 2 1 ... believeng that feasible solutions won't be that far away from the unfeasible one I start with and thus the number of iterations will keep quite low. Does this make any sense? If yes, how can I iterate the choices (grouped combinations) of each group keeping "as near as possibile" to the previous iteration? Option 2: Change the comparation term I tried to think how to find a better variable to sort the choices on. I thought at a measure of how "precious" a resource is based on supply and demand, so that an higer demand of a more precious resource will push you down the list, but this didn't help at all. Also I thought there probably isn't gonna be such a comparsion variable which assures me a feasible solution at first strike. I there such a variable? If not, is there a better sorting criteria anyways? Option 3: implement any known sub-optimal fast solving algorithm Unfortunately I could not find any of such algorithms online. Any suggestion?
