• Various issues linked to my CD drive, when it has a disc in it

  - by Voyagerfan5761

  When I go to the Desktop and click on a media icon (for my flash drive, a CD, whatever it is), the following problems occur, in this approximate sequence: Nautilus will close if it's open. the desktop icons disappear my Window List shows a button that says "Starting File Manager" the icons reappear the button in Window List disappears Because of this problem, I can no longer drag and drop media, nor can I right-click to perform actions such as "Eject" and "Safely Remove Drive". The same symptoms occur if I click a media icon (that is also present on the desktop) in Nautilus' Computer view, though notably not if I click in the places list on the left. I have confirmed that this problem happens only if there is a CD in the drive (Matshita UJDA360). Also, inserting a disc into the CD drive appears to kill all running programs and restart Nautilus (or X; I'm not sure). Applications like Brasero and Rhythmbox will not start while there is a disc in the drive. Removing the disc doesn't result in the list of media updating; it must be forced to update by clicking on one of the desktop icons and going through one of the above-described cycles. It doesn't seem to matter what type of disc is in the drive. This has happened with CD-RWs I burned years ago using Roxio on Windows XP, the Ubuntu disc I installed from (burned with InfraRecorder Portable under Windows XP), and the retail game disc for Star Trek Armada II. The first indication of a problem was Brasero dying when I tried to insert a disc for erasure and rewriting. Since then, I've drafted several different questions on various issues, finally combining them into this one when I realized that having a CD in the drive was the common link. Could this be a simple driver issue? If Ubuntu is dynamically detecting my hardware on boot, can I specify drivers for devices that I know will be a problem if the default files are used? I'm beginning to think that my laptop, an old Dell Inspiron 2650, is just too old or proprietary-driver-hungry (or something, maybe RAM-starved) for Ubuntu and Windows XP to play nicely alongside each other. Or maybe I just need to carefully take my wall-wart machine to a coffee shop for an afternoon so I can download updates and such from the Internet, as I lack a home connection.

• ASP.NET Web Forms is bad, or what am I missing?

  - by iveqy

  Being a PHP guy myself I recently had to write a spider to an asp.net site. I was really surprised by the different approach to ajax and form-handling. For example, in the PHP sites I've worked with, a deletion of a database entry would be something like: GET delete.php?id=&confirm=yes and get a "success" back in some form (in the ajax case, probably a json reply). In this asp.net application you would instead post a form, including all inputs on the page, with a huge __VIEWSTATE and __EVENTVALIDATION. This would be more than 10 times as big as above. The reply would be the complete side again, with a footer containing some structured data for javascript to parse and display the result. Again, the whole page is sent, and then throwed away(?) since it's already displayed. Why not just send the footer with the data to parse (it's not json nor xml but a | separated list). I really can't see why you would design a system that way. Usually you've a fast client, and a somewhat fast server but a really slow connection. Why not keep the datatransfer to a minimum? Why those huge __VIEWSTATE and __EVENTVALIDATION? It seems that everything is done way to chatty and way to complicated. I really can't see the point and that usually means that I'm missing something. So please tell me, what are the reasons for this design and what benefits (and weaknesses) does it have? (Yes I know that __VIEWSTATE is used to tell what type of form-konfiguration should be sent back to the server. But WHY is this needed?) Please keep this discussion strictly technical and avoid flamewars. Update: Please excuse the somewhat rantish question. I tried to explain my view to be able to get a better answer. I am not saying that asp.net is bad, I am saying that I don't understand the meaning of those concepts. Usually that means that I've things to learn instead of the concepts beeing wrong. I appreciate the explanations about that "you don't have to do this way in asp.net", I'll read up on MVC and other .net technologies. However, there most be a reason for this site (the one I referred to) to be written the way it is. It's written by professionals for a big organisation with far more experience than what I've. Any explanation about their (possible) design choice would be welcome.

• Pretty URL in ADF Faces of JDeveloper 11.1.2.2

  - by Frank Nimphius

  Many features planned for Oracle JDeveloper 12c find their way into current releases of Oracle JDeveloper 11g R1 and JDeveloper 11g R2. One example of such a feature is "pretty URL" - or "clean URL" as the Oracle JDeveloper 11g R2 (11.1.2.2) documentation puts it. "A.2.3.24 Clean URLs Historically, ADF Faces has used URL parameters to hold information, such as window IDs and state. However, URL parameters can prevent search engines from recognizing when URLs are actually the same, and therefore interfere with analytics. URL parameters can also interfere with bookmarking. By default, ADF Faces removes URL parameters using the HTML5 History Management API. If that API is unavailable, then session cookies are used.You can also manually configure how URL parameters are removed using the context parameter oracle.adf.view.rich.prettyURL.OPTIONS. Set the parameter to off so that no parameters are removed. Set the parameter to useHistoryApi to only use the HTML5 History Management API. If a browser does not support this API, then no parameters will be removed. Set the parameter to useCookies to use session cookies to remove parameters. If the browser does not support cookies, then no parameters will be removed." See: http://docs.oracle.com/cd/E26098_01/web.1112/e16181/ap_config.htm#ADFUI12856 So basically, what this part in the documentation says is: In JDeveloper 11g R2 (11.1.2.2), Oracle ADF Faces automatically removes its internally used dynamic parameters from the URL You can influence the setting with the prettyURL.OPTIONS context option, which however is not recommended you to do because the default behavior is able to detect if the browser client supports HTML 5 History management or not. In the latter case it the uses a session cookie and if this doesn't work, falls back to the "old" URL parameter adding. The information that is not so explicit and clearly mentioned in the documentation is that this is only for ADF Faces parameters (such as _afrLoop, Adf-Window-Id, etc.), but not the ADF controller token (_adf.ctrl-state)! Removing the ADF controller token is an enhancement request that will be implemented in Oracle JDeveloper 12c

• JGridView (Part 2)

  - by Geertjan

  The second sample in the JGrid download is a picture viewer that needs to be seen to be believed. Here it is, integrated into a NetBeans Platform application (click to enlarge it): When you mouse over the images, they change, showing several different images instantaneously. Here's the explorer view above, mainly making use of code from the sample: public class JGridView extends JScrollPane { @Override public void addNotify() { super.addNotify(); final ExplorerManager em = ExplorerManager.find(this); if (em != null) { final JGrid grid = new JGrid(); Node root = em.getRootContext(); final Node[] nodes = root.getChildren().getNodes(); final PicViewerObject[] pics = new PicViewerObject[nodes.length]; for (int i = 0; i < nodes.length; i++) { Node node = nodes[i]; pics[i] = node.getLookup().lookup(PicViewerObject.class); } grid.getCellRendererManager().setDefaultRenderer(new PicViewerRenderer()); grid.setModel(new DefaultListModel() { @Override public int getSize() { return pics.length; } @Override public Object getElementAt(int i) { return pics[i]; } }); grid.setFixedCellDimension(160); grid.addMouseMotionListener(new MouseAdapter() { int lastIndex = -1; @Override public void mouseMoved(MouseEvent e) { if (lastIndex >= 0) { Object o = grid.getModel().getElementAt(lastIndex); if (o instanceof PicViewerObject) { Rectangle r = grid.getCellBounds(lastIndex); if (r != null && !r.contains(e.getPoint())) { ((PicViewerObject) o).setMarker(false); grid.repaint(r); } } } int index = grid.getCellAt(e.getPoint()); if (index >= 0) { Object o = grid.getModel().getElementAt(index); if (o instanceof PicViewerObject) { Rectangle r = grid.getCellBounds(index); if (r != null) { ((PicViewerObject) o).setFraction(((float) e.getPoint().x - (float) r.x) / (float) r.width); ((PicViewerObject) o).setMarker(true); lastIndex = index; grid.repaint(r); } } } } }); grid.getSelectionModel().addListSelectionListener(new ListSelectionListener() { @Override public void valueChanged(ListSelectionEvent e) { //Somehow compare the selected item //with the list of books and find a matching book: int selectedIndex = grid.getSelectedIndex(); for (int i = 0; i < nodes.length; i++) { int picId = pics[i].getId(); if (selectedIndex == picId) { try { em.setSelectedNodes(new Node[]{nodes[i]}); } catch (PropertyVetoException ex) { Exceptions.printStackTrace(ex); } } } } }); setViewportView(grid); } } } The next step is to create a generic JGridView that will handle any kind of object automatically.

• Thoughts on schemas and schema proliferation

  - by jamiet

  In SQL Server 2005 Microsoft introduced user-schema separation and since then I have seen the use of schemas increase; whereas before I would typically see databases where all objects were in the [dbo] schema I now see databases that have multiple schemas, a database I saw recently had 31 (thirty one) of them. I can’t help but wonder whether this is a good thing or not – clearly 31 is an extreme case but I question whether multiple schemas create more problems than they solve? I have been involved in many discussions that go something like this: Developer #1> “I have a new function to add to the database and I’m not sure which schema to put it in” Developer #2> “What does it do?” Developer #1> “It provides data to a report in Reporting Services” Developer #2> “Ok, so put it in the [reports] schema” Developer #1> “Well I could, but the data will only be used by our Financial reporting folks so shouldn’t I put it in the [financial] schema?” Developer #2> “Maybe, yes” Developer #1> “Mind you, the data is supposed to be used for regulatory reporting to the FSA, should I put it in [regulatory]?” Developer #2> “Err….” You get the idea!!! The more schemas that exist in your database then the more chance that their supposed usages will overlap. I’m left wondering whether the use of schemas is actually necessary. I don’t view really see them as an aid to security because I generally believe that principles should be assigned permissions on objects as-needed on a case-by-case basis (and I have a stock SQL query that deciphers them all for me) so why bother using them at all? I can envisage a use where a database is used to house objects pertaining to many different business functions (which, in itself, is an ambiguous term) and in that circumstance perhaps a schema per business function would be appropriate; hence of late I have been loosely following this edict: If some objects in a database could be moved en masse to another database without the need to remove any foreign key constraints then those objects could legitimately exist in a dedicated schema. I am interested to know what other people’s thoughts are on this. If you would like to share then please do so in the comments. @Jamiet

• How exactly is Google Webmaster Tools measuring "Site Performance"?

  - by Rémi

  I've been working for two months now on improving our response time (mainly server side) on a new forum (a brand new product on a technical point of view) we've launched in Germany a few month ago and I'm a lot surprised by the results I get. I monitor our response time using Apache logs and our own implementation of Boomerang beacon. Using my stats, I can see that our new product responds in about 680 ms where our old product was responding in about 1050 ms. On the other side, Google Webmaster Tool tells us that our pages have an average reponse time of about 1500 ms today where it was 700 three months ago with our old product. I've figured that GWT was taking client side metrics into account so I've added some measures on our Boomerang beacon and everything looks just fine. I've also ran some random pages on ySlow and Google's Page Speed and everything looks better than it was before. We event have a 82% on Google's Page Speed tool which is quite cool for a site with some ads in it :) Lately, we have signed a deal with Akamai to use two of their products : CDN for our static files (we were using another CDN before but it wasn't very effective) and RMA to improve Networks routes. We have also introduced a new agressive cache mecanism to ensure that most of the pages served to crawlers are cached by our memcache grid. After checking my metrics, it seems that this changes have improved from 650ms to about 500ms, which is good (still not great but it is definitly an improvement). But webmaster tools continues to report an increasing average response time where we see it decreasing in the same time. Have you ever had the same kind of wierd behavior on your sites while doing performance improvements ? Do you have any idea how to monitor the same thing Google does with Site Performance in Google Webmaster Tools so that we could improve our site and constantly check if it is what Google wants ? Edit 2011/07/26 : Thanks for your answers guys ! Nevertheless, I was not precise enough. The main issue we have is not with the Site Performance page but with the Crawl Stats one for now. We probably found an issue on our side with some very slow pages (around 3000 ms !!) and we are trying to fix them. I'll keep you posted as soon I'll have some infos. Thanks again !

• How to leverage the internal HTTP endpoint available on Azure web roles?

  - by Alfredo Delsors

  Imagine you have a Web application using an in-memory collection that changes occasionally but is used very often. The collection gets loaded from storage on the Application_Start global.asax event and is updated whenever its content changes. If you want to deploy this application on Azure you need to keep in mind that more than one instance of the application can be running at any time and therefore you need to provide some mechanism to keep all instances informed with the latest changes. Because the communication through internal endpoints between Azure role instances is at no cost, a good solution can be maintaining the information on Azure Storage Tables, reading its contents on the Application_Start event and populating its changes to all other instances using the internal HTTP port available on Azure Web Roles. You need to follow these steps to leverage the internal HTTP endpoint available on Azure web roles to maintain all instances up to date. 1.   Define an internal HTTP endpoint in the Web Role properties, for example InternalHttpEndpoint   2.   Add a new WCF service to the Web Role, for example NotificationService.svc 3.   Disable multiple site bindings in web.config: <serviceHostingEnvironment multipleSiteBindingsEnabled="false"> 4.   Add a method on the new service to receive notifications from other role instances. namespace Service { [ServiceContract] public interface INotificationService { [OperationContract(IsOneWay = true)] void Notify(Information info); } } 5.   Declare a class that inherits from System.ServiceModel.Activation.ServiceHostFactory and override the method CreateServiceHost to host the internal endpoint. public class InternalServiceFactory : ServiceHostFactory { protected override ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses) { var internalEndpointAddress = string.Format( "http://{0}/NotificationService.svc", RoleEnvironment.CurrentRoleInstance.InstanceEndpoints["InternalHttpEndpoint"].IPEndpoint); ServiceHost host = new ServiceHost( typeof(NotificationService), new Uri(internalEndpointAddress)); BasicHttpBinding binding = new BasicHttpBinding(SecurityMode.None); host.AddServiceEndpoint( typeof(INotificationService), binding, internalEndpointAddress); return host; } } Note that you can use SecurityMode.None because the internal endpoint is private to the instances of the service. 6.   Edit the markup of the service right clicking the svc file and selecting "View markup" to add the new factory as the factory to be used to create the service <%@ ServiceHost Language="C#" Debug="true" Factory="Service.InternalServiceFactory" Service="Service.NotificationService" CodeBehind="NotificationService.svc.cs" %> 7.   Now you can notify changes to other instances using this code: var current = RoleEnvironment.CurrentRoleInstance; var endPoints = current.Role.Instances .Where(instance => instance != current) .Select(instance => instance.InstanceEndpoints["InternalHttpEndpoint"]); foreach (var ep in endPoints) { EndpointAddress address = new EndpointAddress( String.Format("http://{0}/NotificationService.svc", ep.IPEndpoint)); BasicHttpBinding binding = new BasicHttpBinding(SecurityMode.None); var factory = new ChannelFactory<INotificationService>(binding); INotificationService instance = factory.CreateChannel(address); instance.Notify(changedinfo); }

• Workflow 4.5 is Awesome, cant wait for 5.0!

  - by JoshReuben

  About 2 years ago I wrote a blog post describing what I would like to see in Workflow vnext: http://geekswithblogs.net/JoshReuben/archive/2010/08/25/workflow-4.0---not-there-yet.aspx At the time WF 4.0 was a little rough around the edges – the State Machine was on codeplex and people were simulating state machines with Flowcharts. Last year I built a near- realtime machine management system using WF 4.0.1 – its managing the internal operations of this device: http://landanano.com/products/commercial   Well WF 4.5 has come a long way – many of my gripes have been addressed: C# expressions - no more VB 'AndAlso' clauses state machine awesomeness - can query current state many designer improvements - Document Outline is so much more succinct than Designer! Separate WCF Service Contract interfaces and ability to generate activities from contract operations ability to rehydrate to updated flow definitions via DynamicUpdateMap and WorkflowIdentity you can read about the new features here: http://msdn.microsoft.com/en-us/library/hh305677(VS.110).aspx   2013 could be the year of Workflow evangelism for .NET, as it comes together as the DSL language. Eg on Azure it could be used to graphically orchestrate between WebRoles, WorkerRoles and AppFabric Queues and the ServiceBus – that would be grand.   Here’s a list of things I’d like to see in Workflow 5.0: Stronger Parallelism support for true multithreaded workflows . A Workflow executes on a single thread – wouldn’t it be great if we had the ability to model TPL DataFlow? Parallel is not really parallel, just allows AsyncCodeActivity.     support for recursion an ExpressionTree activity with an editor design surface a math activity pack return of application level protocol (3.51 WF services) – automatically expose a state machine as a WCF service with bookmark Receive activities generated from OperationContract automatically placed in state transition triggers. A new HTML5 ActivityDesigner control – support with different CSS3  skinnable hooks,  remote connectivity (had to roll my own) A data flow view – crucial to understanding the big picture Ability to refactor a Sequence to custom activity in a separate .xaml file – like Expression Blend does for UserControl state machine global error handling - if all states goto an error state, you quickly get visual spagetti. Now you could nest a state machine, but what if you want an application level protocol whereby each state exposes certain WCF ops. DSL RAD editing - Make the Document Outline into a DSL editor for adding activities  – For WF to really succeed as a higher level of abstraction, It needs to be more productive than raw coding - drag & drop on the designer is currently too slow compared to just typing code. Extensible Wizard API - for pluggable WF editor experience other execution models beyond Sequence, Flowchart & StateMachine: SSIS, Behavior Trees,  Wolfram Model tool – surprise us! improvements to Designer debugging API - SourceLocation is tied to XAML file line number and char position, and ModelService access seems convoluted - why not leverage WPF LogicalTreeHelper / VisualTreeHelper ? Workflow Team , keep on rocking!

• Lock mouse in center of screen, and still use to move camera Unity

  - by Flotolk

  I am making a program from 1st person point of view. I would like the camera to be moved using the mouse, preferably using simple code, like from XNA var center = this.Window.ClientBounds; MouseState newState = Mouse.GetState(); if (Keyboard.GetState().IsKeyUp(Keys.Escape)) { Mouse.SetPosition((int)center.X, (int)center.Y); camera.Rotation -= (newState.X - center.X) * 0.005f; camera.UpDown += (newState.Y - center.Y) * 0.005f; } Is there any code that lets me do this in Unity, since Unity does not support XNA, I need a new library to use, and a new way to collect this input. this is also a little tougher, since I want one object to go up and down based on if you move it the mouse up and down, and another object to be the one turning left and right. I am also very concerned about clamping the mouse to the center of the screen, since you will be selecting items, and it is easiest to have a simple cross-hairs in the center of the screen for this purpose. Here is the code I am using to move right now: using UnityEngine; using System.Collections; [AddComponentMenu("Camera-Control/Mouse Look")] public class MouseLook : MonoBehaviour { public enum RotationAxes { MouseXAndY = 0, MouseX = 1, MouseY = 2 } public RotationAxes axes = RotationAxes.MouseXAndY; public float sensitivityX = 15F; public float sensitivityY = 15F; public float minimumX = -360F; public float maximumX = 360F; public float minimumY = -60F; public float maximumY = 60F; float rotationY = 0F; void Update () { if (axes == RotationAxes.MouseXAndY) { float rotationX = transform.localEulerAngles.y + Input.GetAxis("Mouse X") * sensitivityX; rotationY += Input.GetAxis("Mouse Y") * sensitivityY; rotationY = Mathf.Clamp (rotationY, minimumY, maximumY); transform.localEulerAngles = new Vector3(-rotationY, rotationX, 0); } else if (axes == RotationAxes.MouseX) { transform.Rotate(0, Input.GetAxis("Mouse X") * sensitivityX, 0); } else { rotationY += Input.GetAxis("Mouse Y") * sensitivityY; rotationY = Mathf.Clamp (rotationY, minimumY, maximumY); transform.localEulerAngles = new Vector3(-rotationY, transform.localEulerAngles.y, 0); } while (Input.GetKeyDown(KeyCode.Space) == true) { Screen.lockCursor = true; } } void Start () { // Make the rigid body not change rotation if (GetComponent<Rigidbody>()) GetComponent<Rigidbody>().freezeRotation = true; } } This code does everything except lock the mouse to the center of the screen. Screen.lockCursor = true; does not work though, since then the camera no longer moves, and the cursor does not allow you to click anything else either.

• 3 Reasons You Need To Know Something About Every Technology

  - by Tim Murphy

  I make my living as a consultant and a general technologist.  I credit my success to the fact that I have never been afraid to pick up any product, language or platform needed to get the job done.  While Microsoft technologies I my mainstay, I have done work on mainframe and UNIX platforms and have worked with a wide variety of database engines.  Each one has it’s use and most times it is less expensive to find a way to communicate with an existing system than to replace it. So what are the main benefits of expending the effort to learn a new technology? New ways to solve problems Accelerate development Advise clients and get new business opportunities By new technology I mean ones that you haven’t had experience with before.  They don’t have to be the the one that just came out yesterday.  As they say, those who do not learn from history are bound to repeat it.  If you can learn something from an older technology it can be just as valuable as the shiny new one.  Either way, when you add another tool to your kit you get a new view on each problem you face.  This makes it easier to create a sound solution. The next thing you can learn from working with different products and techniques is how to more efficiently develop solve problems.  Many times if you are working with a new language you will find that there are specific design patterns that are used with it in normal use.  These can usually be applied with most languages.  You just needed to be exposed to them. The last point is about helping your clients and helping yourself.  If you can get in on technologies early you will have advantage over your competition in the market.  You will also be able to honestly advise you client on why they should or should not go with a new product.  Being able to compare products and their features is always an ability that stake holders appreciate. You don’t need to learn every detail of a product.  Learn enough to function and get an idea of how to use the technology.  Keep eating those technology Wheaties and you will be ready to go the distance in any project. del.icio.us Tags: Technology,technologists,technology generalist,Software Architecture

• Motivating yourself to actually write the code after you've designed something

  - by dpb

  Does it happen only to me or is this familiar to you too? It's like this: You have to create something; a module, a feature, an entire application... whatever. It is something interesting that you have never done before, it is challenging. So you start to think how you are going to do it. You draw some sketches. You write some prototypes to test your ideas. You are putting different pieces together to get the complete view. You finally end up with a design that you like, something that is simple, clear to everybody, easy maintainable... you name it. You covered every base, you thought of everything. You know that you are going to have this class and that file and that database schema. Configure this here, adapt this other thingy there etc. But now, after everything is settled, you have to sit down and actually write the code for it. And is not challenging anymore.... Been there, done that! Writing the code now is just "formalities" and makes it look like re-iterating what you've just finished. At my previous job I sometimes got away with it because someone else did the coding based on my specifications, but at my new gig I'm in charge of the entire process so I have to do this too ('cause I get payed to do it). But I have a pet project I'm working on at home, after work and there is just me and no one is paying me to do it. I do the creative work and then when time comes to write it down I just don't feel like it (lets browse the web a little, see what's new on P.SE, on SO etc). I just want to move to the next challenging thing, and then to the next, and the next... Does this happen to you too? How do you deal with it? How do you convince yourself to go in and write the freaking code? I'll take any answer.

• Why is multithreading often preferred for improving performance?

  - by user1849534

  I have a question, it's about why programmers seems to love concurrency and multi-threaded programs in general. I'm considering 2 main approaches here: an async approach basically based on signals, or just an async approach as called by many papers and languages like the new C# 5.0 for example, and a "companion thread" that manages the policy of your pipeline a concurrent approach or multi-threading approach I will just say that I'm thinking about the hardware here and the worst case scenario, and I have tested this 2 paradigms myself, the async paradigm is a winner at the point that I don't get why people 90% of the time talk about multi-threading when they want to speed up things or make a good use of their resources. I have tested multi-threaded programs and async program on an old machine with an Intel quad-core that doesn't offer a memory controller inside the CPU, the memory is managed entirely by the motherboard, well in this case performances are horrible with a multi-threaded application, even a relatively low number of threads like 3-4-5 can be a problem, the application is unresponsive and is just slow and unpleasant. A good async approach is, on the other hand, probably not faster but it's not worst either, my application just waits for the result and doesn't hangs, it's responsive and there is a much better scaling going on. I have also discovered that a context change in the threading world it's not that cheap in real world scenario, it's in fact quite expensive especially when you have more than 2 threads that need to cycle and swap among each other to be computed. On modern CPUs the situation it's not really that different, the memory controller it's integrated but my point is that an x86 CPUs is basically a serial machine and the memory controller works the same way as with the old machine with an external memory controller on the motherboard. The context switch is still a relevant cost in my application and the fact that the memory controller it's integrated or that the newer CPU have more than 2 core it's not bargain for me. For what i have experienced the concurrent approach is good in theory but not that good in practice, with the memory model imposed by the hardware, it's hard to make a good use of this paradigm, also it introduces a lot of issues ranging from the use of my data structures to the join of multiple threads. Also both paradigms do not offer any security abut when the task or the job will be done in a certain point in time, making them really similar from a functional point of view. According to the X86 memory model, why the majority of people suggest to use concurrency with C++ and not just an async approach ? Also why not considering the worst case scenario of a computer where the context switch is probably more expensive than the computation itself ?

• Is there an API for determining congressional districts?

  - by ardavis

  I'm looking to determine the congressional district based on an address my user is providing. This will avoid having the user to look it up themselves. Does an API of this sort exist? Note Through my attempts to find one, I've only come across these: http://www.govtrack.us/developers/api (not sure how to submit an an address or zip code however) The following resources are available in the API ...Bills and resolutions in the U.S. Congress since 1973 (the 93rd Congress). ...A (bill, person) pair indicating cosponsorship, with join and withdrawn dates. ...Members of Congress and U.S. Presidents since the founding of the nation. ...Terms held in office by Members of Congress and U.S. Presidents. Each term corresponds with an election, meaning each term in the House covers two years (one 'Congress'), as President four years, and in the Senate six years (three 'Congresses'). ...Roll call votes in the U.S. Congress since 1789. How people voted is accessed through the Vote_voter API. ...How people voted on roll call votes in the U.S. Congress since 1789. See the Vote API. Filter on the vote field to get the results of a particular vote... http://www.opencongress.org/api (seems to be a way to find congress information, but not districts) This API provides programmers with structured access to all the data on OpenCongress, everything from official bill info to news and blog coverage to user-generated votes on bills and much more... This API defaults to returning XML. All queries can also return JSON... https://groups.google.com/forum/?fromgroups=#!topic/opendems-discuss/CeKyi_aANaE (similar question, no resolution) I've been looking over Open Dems, and seeing what's exposed at this point and what isn't. I work with Democrats Abroad, and am interested in using stuff from the lab for their sites. I quickly looked over the Precinct API, which does both more and less than what I'd need. An ideal resource would be any way of translating addresses into CD at the very least (getting state district data would be good as well), since that would make it easier for DA's membership to make a difference in races like last month's NY26 race... Update I'm looking at the source for the govtrack.us website and the 'doGeoCode' function may be useful. view-source:http://www.govtrack.us/congress/members If no one has any suggestions, I will try to go off of what they are doing.

• New Worklist features on 12.1.3

  - by Vijay Shanmugam

  Following new Worklist features are available on E-Business Suite 12.1.3 via Patch 13646173. Ability to view comments on top of a notification If an action is performed on a notification such as Reassign, Request for Information or Provide Information, the recipient of the notification will see who performed the last action and the associated comment on top of the notification. Reassigning a request for information notification If an approver requests more information on a notification from it's submitter, the submitter now has two options Answer Request for More Information Transfer Request for More Information If the submitter thinks the requested information can be provided by another user, he/she can transfer the request to the other user. Please note that only Transfer is supported for Request for More Information. Once transferred, the submitter cannot access the notification and provide the requested information. Use actual sent date when reassigning a notification The Sent field in notification header always showed the date on which the notification was first created. If the notification was later reassigned, the Sent date was not updated to show the last action date. This caused problems in following scenario Approval notification was sent to JACK on 01-JAN-2012 JACK waited for 10 days before reassigning to JILL on 10-JAN-2012 JILL does not see the notification as sent on 10-JAN-2012, instead sees it as sent on 01-JAN-2012 Although the notification was originally created on 01-JAN-2012, it was sent to JILL only on 10-JAN-2012 The enhancement now shows the correct sent date in Worklist and Notification Details page. Figure 1 - Depicts all the above 3 features Related Action History for response required notification So far it was possible to embed Action History of an response-required notification into another FYI notification using #RELATED_HISTORY attribute (Please refer to Workflow Developer Guide for details about this attribute). The enhancement now enables developers to embed Action History of one response-required notification into another response-required notification. To embed Action History of one response-required notification into another, create message attribute #RELATED_HISTORY. To this attribute set a value during run-time in the following format. {TITLE}[ITEM_TYPE:ITEM_KEY]PROCESS_NAME:ACTIVITY_LABEL_NAMEThe TITLE, ITEM_TYPE and ITEM_KEY are optional values. TITLE is used as Related Action History header title. If TITLE is not present, then a default title "Related Action History" is shown. If ITEM_TYPE is present and ITEM_KEY is not, For Example: {TITLE}[ITEM_TYPE]PROCESS_NAME:ACTIVITY_LABEL_NAME , the Related Action History is populated from parent item type of the current item. If both ITEM_TYPE and ITEM_KEY is present, For Example: {TITLE}[ITEM_TYPE:ITEM_KEY]PROCESS_NAME:ACTIVITY_LABEL_NAME , the Related Action History is populated from that specific instance activity.

• What could be the best way to generalize data from Facebook and Twitter?

  - by Sjaak van der Heide

  I am not sure if this is the best subsite to ask this question, but I'm pretty sure it doesn't fit on the normal or facebook SO page... I've been asked to make a general API for connecting to several Social Media platforms (at the moment Facebook and Twitter). I have already realised both of them seperately. Meaning I retrieve the data I need from both Facebook and Twitter and hold the data in it's own dataclass. In my case a list of FacebookTimelineItems and a list of TwitterTimelineItems. now the hard part is taking the parts that are used in both (username, id, message and such) and make 1 general class that is eventually passed on to who/whatever sent the call to my API. these are two pics of the data classes I have: http://imageshack.us/photo/my-images/703/facebookdata.png/ http://imageshack.us/photo/my-images/204/twitterdata.png/ probably not 100% correct but it gives an idea what it looks like. Now I've been having several idea about how to go about and generalize the two, which is harder then I thought at first. Create an interface (TimelineItem) and let the other classes extend that one. this way I'll always be sure I have a class that contains at least the basic info I need. downside is that deserializing the JSON seems to be a nightmare. Use the two dataclasses I have and combine them into a new class afterwards, then pass that one back to whoever requested it. This would probably work but I get the idea it's not the best way to tackle this problem, and is pretty dodgy IF I get it working. Or, in case of the other two being nearly impossible. Keep the two seperated in the front end, and go sit in the corner crying because I've just figured out you can't lump together facebook and twitter... Note: I don't have to make the front end part (view), I just make sure the Model is nicely filled with data :) I hope I placed this in the right section, if I didn't I apologise and would like to know where I should go with my question. Thanks in advance for any replied/ideas/opinions on this.

• Lookup Viewer

  - by Geertjan

  The Maven integrated view that I showed yesterday I was able to create because I happened to know that an implementation of SubprojectProvider and LogicalViewProvider are in the Lookup of Maven projects. With that knowledge, I was able to use and even delegate to those implementations. But what if you don't know that those implementations are in the Lookup of the Project object? In the case of the Maven Project implementation, you could look in the source code of the Maven Project implementation, at the "getLookup" method. However, any other module could be putting its own objects into that Lookup, dynamically, i.e., at runtime. So there's no way of knowing what's in the Lookup of any Project object or any other object with a Lookup. But now imagine that you have a Lookup Viewer, as a tool during development, which you would exclude when distributing the application. Whenever new objects are found in the Lookup, the viewer displays them. You could install the Lookup Viewer into NetBeans IDE, or any other NetBeans Platform application, and then get a quick impression of what's actually in the Lookup when you select a different item in the application during development. Here it is (though I vaguely remember someone else writing something similar): Above, a Maven Project is selected. The Lookup Window shows that, among many other classes, an implementation of SubprojectProvider and LogicalViewProvider are found in the Lookup when the Maven Project is selected. If an item in the Lookup Window has its own Lookup, the content of that Lookup is displayed as child nodes of the Lookup, etc, i.e., you can explore all the way down the Lookup of each item found within objects found within the current selection. (What's especially fun is seeing the SaveCookieImpl being added and removed from the Lookup Window when you make/save a change in a document.) Another example is below, showing the Lookup Window installed in a custom application created during a course at MIT in Boston: A small trick I had to apply is that I always show the previous Lookup, since the current Lookup, when you select one of the Nodes in the Lookup Window, would be the Lookup of the Lookup Window itself! If anyone is interested in this, I can publish the NetBeans module providing the above window to the NetBeans update center.

• What is 'Ubuntu Unity' (for the Desktop)?

  - by Martin

  Ok, so there's the buzz of Canonical (wanting to) switch for new Ubuntu version from the GNOME default desktop to their own Unity shell. (I hope that's accurate.) It seems I can not totally fathom what Unity actually is. For looking at its homepage it currently is firmly targeted at netbooks and the somehow different usage model on these. Is it a classical desktop? -- Taskbar? Shortcuts? Is the difference between Ubuntu(GNOME)+Unity more/less pronounced than the difference between Ubuntu and Kubuntu? Will "my parents" be able to get the interface if they've been using the classical gnome desktop so far? Edit: I would not like to split this up into more specific questions, as What is Unity? is exactly what the people I set up Ubuntu boxes for will ask me if they hear that the newer Ubuntu version is using that instead of the Desktop -- and it might well happen someone phrases it like that :-) I will certainly not give them the link to the HP as the explanation there does not lay out if it is a desktop or something more or something less: (It does not for me - therefore I'm asking here.) Unity is designed for netbooks and related touch-based devices. It includes [...] that makes it fast and easy to access [...] while removing screen elements that are rarely used in mobile and netbook computing. (emphasis mine) -- the explanation there doesn't even mention the desktop-PC! Unity has a vertical task management panel on the left-hand side and a menu panel at the top of the screen. [...] This sounds like a re-themed normal desktop. Clicking on an icon will give the target application focus if it is already running or launch it if it is not already running. If you click the ... Aha. Sounds like Windows 7. ... icon of an application that already has focus, Unity will activate an Expose-style view of all the open windows associated with that application. No clue what that's supposed to be. So it would really be nice if someone could explain for non desktop-design-terms experts what Unity is.

• DTLoggedExec 1.1.2008.4 Released!

  - by Davide Mauri

  Today I've relased the latest version of my DTExec replacement tool, DTLoggedExec. The main changes are the following: Used a new strategy for version numbers. Now it will follow the following pattern Major.Minor.TargetSQLServerVersion.Revision Added support for Auto Configurations Fixed a bug that reported incorrect number of errors and warnings to Log Providers Fixed a buf that prevented correct casting of values when using /Set and /Param options Errors and Warnings are now counted more precisely. Updated database and log import scripts to categorize logs by projects and sections. E.g.: Project: MyBIProject; Sections: Staging, Datawarehouse Removed unused report stored procedures from database Updated Samples: 12 samples are now available to show ALL DTLoggedExec features From this version only SSIS 2008 will be supported http://dtloggedexec.codeplex.com/releases/view/62218  It useful to say something more on a couple of specific points: From this version only SSIS 2008 will be supportedYes, Integration Services 2005 are not supported anymore. The latest version capable of running SSIS 2005 Packages is the 1.0.0.2. Updated database and log import scripts to categorize logs by projects and sectionsWhen you import a log file, you can now assign it to a Project and to a Section of that project. In this way it's easier to gather statistical information for an entire project or a subsection of it. This also allows to store logged data of package belonging to different projects in the same database. For example:  Updated SamplesA complete set of samples that shows how to use all DTLoggedExec features are now shipped with the product. Enjoy! Added support for Auto ConfigurationsThis point will have a post on its own, since it's quite important and is by far the biggest new feature introduced in this release. To explain it in a few words, I can just say that you don't need to waste time with complex DTS configuration files or options, since a package will configure itself automatically. You just need to write a single statement as a parameter for DTLoggedExec. This feature can simplify deployment *a lot* :)   I the next days I'll write the mentioned post on Auto-Configurations and i'll update the documentation available on theDTLoggedExec website:   http://dtloggedexec.davidemauri.it/MainPage.ashx

• Are there any concerns with using a static read-only unit of work so that it behaves like a cache?

  - by Rowan Freeman

  Related question: How do I cache data that rarely changes? I'm making an ASP.NET MVC4 application. On every request the security details about the user will need to be checked with the area/controller/action that they are accessing to see if they are allowed to view it. The security information is stored in the database. For example: User Permission UserPermission Action ActionPermission A "Permission" is a token that is applied to an MVC action to indicate that the token is required in order to access the action. Once a user is given the permission (via the UserPermission table) then they have the token and can therefore access the action. I've been looking in to how to cache this data (since it rarely changes) so that I'm only querying in-memory data and not hitting a database (which is a considerable performance hit at the moment). I've tried storing things in lists, using a caching provider but I either run in to problems or performance doesn't improve. One problem that I constantly run in to is that I'm using lazy loading and dynamic proxies with EntityFramework. This means that even if I ToList() everything and store them somewhere static, the relationships are never populated. For example, User.Permissions is an ICollection but it's always null. I don't want to Include() everything because I'm trying to keep things simple and generic (and easy to modify). One thing I know is that an EntityFramework DbContext is a unit of work that acts with 1st-level caching. That is, for the duration of the unit of work, everything that is accessed is cached in memory. I want to create a read-only DbContext that will exist indefinitely and will only be used to read about permission data. Upon testing this it worked perfectly; my page load times went from 200ms+ to 20ms. I can easily force the data to refresh at certain intervals or simply leave it to refresh when the application pool is recycled. Basically it will behave like a cache. Note that the rest of the application will interact with other contexts that exist per request as normal. Is there any disadvantage to this approach? Could I be doing something different?

• Focusing on Mobile @ Oracle OpenWorld

  - by Carlos Chang

  Plenty of exciting trends in the industry today: Cloud, Big Data, Mobile, etc. The first two are amazing of course, but for me, it's mobile, mobile and... MOBILE.   Why? Think back to the mozilla browser (Marc Andreessen's mozilla, not today's mozilla.org), Netscape and the nascent beginnings of the World Wide Web. Amazing times. Companies were just starting to set up their home pages, basic HTML, hyperlinks, images, ooooh, aaaah.  Yahoo! was *the* search engine back then. :-\   Anywhoo, I would pose that mobile today, we are in a similar junction. Sure, there's millions of apps on Apple's App Store and Google Play, but within the enterprise, it's just getting started. I'm talking about going beyond the simple, tactical apps such as calendaring, contacts or directory service lookup. And while mobile first a common mantra, I'm referring to mobile plus which includes and looks upon the whole enterprise holistically and adds new parameters, such as your GPS location, perhaps even your vital signs. (Apple's health kit?)  Everything is going mobile. Everything connected. But with the enterprise - scalability, security, integration, app management, user management, etc. Amazing times ahead. Ok, got that off my mind. Oracle OpenWorld 2014 - Going Mobile!  If you're coming to the big dance, I've highlighted some key mobile sessions below. And if you see me around, and there's a bar within reach, high five me for a beer. I mean, if you read this far, and didn't already jump to the list below, I think you deserve one.   Cheers!  Monday, 9/29/14 at 10:15 AM - General Session: Time for You to Rethink Mobile?
