  • Building the Website From Scratch

    Almost everyone is building a website these days, but by saying that one is building the website from scratch, he implies that his knowledge on the matter is almost non-existent. In this case, seeking for answers online can overwhelm him with information. Therefore, instead of trying to learn all the processes involved in building the website by reading about it, a better option would be to go ahead at building one and learn the ropes hands on.

  • Is there a canonical book on general abstractions and modeling?

    - by David The Man
    I've been trying to understand the fundamentals of general abstractions and modeling: there are quite a lot of books when you search for abstractions, but most of those seem to be about learning object-oriented programming in a given language. Is there a book out there that's the de-facto standard for describing best practices, design methodologies, and other helpful information about general abstractions and modeling? What about that book makes it special?

  • Will Online Learning Save Higher Education (and does it need saving)?

    - by user739873
    A lot (an awful lot) of education industry rag real estate has been devoted to the topics of online learning, MOOC’s, Udacity, edX, etc., etc. and to the uninitiated you’d think that the education equivalent of the cure for cancer had been discovered. There are certainly skeptics (whose voice is usually swiftly trampled upon by the masses) who feel we could over steer and damage or destroy something vital to teaching and learning (i.e. the classroom experience and direct interaction with human beings known as instructors), but for the most part prevailing opinion seems to be that online learning will take over the world and that higher education will never be the same. Now I’m sure that since you all know I work for a technology company you think I’m going to come down hard on the side of online learning proselytizers. Yes, I do believe that this revolution can and will provide access to massive numbers of individuals that either couldn’t afford (from a fiscal or time perspective) a traditional education, and that in some cases the online modality will actually be an improvement over certain traditional forms (such as courses taught by an adjunct or teaching assistant that has no business being a teacher). But I think several things need immediate attention or we’re likely to get so caught up in the delivery that we miss some of the real issues (and opportunities) around online learning. First and foremost, we’ve got to give some thought to how traditional information systems are going to accommodate thousands (possibly hundreds of thousands) of individual students each taking courses from many, many different “deliverers” with an expectation that successful completion of these courses will result in credit at many or most institutions. There’s also a huge opportunity to refine the delivery platform (no, LMS is not a commodity when you are talking about online delivery being your sole mode of operation) as well as the course itself by mining all kinds of data from the interactions that the students have with the material each time they take it. Social data analytics tools will be key in achieving this goal. What about accreditation (badging or competencies vs. traditional degrees)? And again, will the information systems in place today adapt to changes in this area fast enough? The type of scale that this shift in learning could drive has the potential to abruptly overwhelm just about every system in place today in higher education. I would like to (with a not so gentle reminder) refer you back to a blog entry I wrote when I first stepped into my current role at Oracle in which I talked about how higher ed needs an “Oracle” more than at any other time in it’s evolution (despite the somewhat mercantilist reputation it has in some circles). There just aren’t that many organizations that can deliver the kinds of solutions “at scale” that this brave new world of online education will demand. The future may be closer than we think. Cole

    - by Shervanator
    i'm currently in the process of creating a Windows 8 applicaiton using SharpDX (the managed c# directx wrapper). However I have ran into problems with one of my shaders and I want to know if its possible to debug such applications. PIX doesn't seem to work of directX apps as the executable does not like opening directly, and the new visual studio graphics debugging toolkit in VS2012 always states "unable to start the experiment" when I try to capture any information about my session. Thanks!

  • Combobox binding with different types

    - by George Evjen
    Binding to comboboxes in Silverlight has been an adventure the past couple of days. In our framework at ArchitectNow we use LookupGroups and LookupValues. In our database we would have a LookupGroup of NBA Teams for example. The group would be called NBATeams, we get the LookupGroupID and then get the values from the LookupValues table. So we would end up with a list of all 30+ teams. Our lookup values entity has a display text(string), value(string), IsActive and some other fields. With our applications we load all this information into the system when the user is logging in or right after they login. So in cache we have a list of groups and values that we can get at whenever we want to. We get this information in our framework simply by creating an observable collection of type LookupValue. To get a list of these values into our property all we have to do is. var NBATeams = AppContext.Current.LookupSerivce.GetLookupValues(“NBATeams”); Our combobox then is bound like this. (We use telerik components in most if not all our projects) <telerik:RadComboBox ItemsSource="{Binding NBATeams}”></telerik:RadComboBox> This should give you a list in your combobox. We also set up another property in our ViewModel that is a just single object of NBATeams  - “SelectedNBATeam” Our selectedItem in our combobox would look like, we would set this to a two way binding since we are sending data back. SelectedItem={Binding SelectedNBATeam, mode=TwoWay}” This is all pretty straight forward and we use this pattern throughout all our applications. What do you do though when you have a combobox in a ItemsControl or ListBox? Here we have a list of NBA Teams that are a string that are being brought back from the database. We cant have the selected item be our LookupValue because the data is a string and its being bound in an ItemsControl. In the example above we would just have the combobox in a form. Here though we have it in a ItemsControl, where there is no selected item from the initial ItemsSource. In order to get the selected item to be displayed in the combobox you have to convert the LookupValue to a string. Then instead of using SelectedItem in the combobox use SelectedValue. To convert the LookupValue we do this. Create an observable collection of strings public ObservableCollection<string> NBATeams { get; set;} Then convert your lookups to strings var NBATeams = new ObservableCollection<string>(AppContext.Current.LookupService.GetLookupValues(“NBATeams”).Select(x => x.DisplayText)); This will give us a list of strings and our selected value should be bound to the NBATeams property in our ItemsSource in our ItemsControl. SelectedValue={Binding NBATeam, mode=TwoWay}”

  • Any technical references for game-oriented icons and symbols?

    - by willc2
    To make localizing easier, I'm using icons to show in-game information like achievements and bonuses. Coming up with good designs isn't easy, especially when it has to be integrated into the rest of the game's art style. Can I do better than looking at some random selection of existing games? Are there any reference books or sites that cover game graphics specifically? I'm looking for more theory and best-practices rather than pre-made graphics.

  • Is it OK to use sample code from blogs, GitHub, etc... in commercial applications?

    - by eterps
    When searching the web for a solution to a particular problem, I often find a perfect solution posted on someone's blog, or in a public repository (GitHub, Google Code). Most of the time, the code has no copyright information, nor does the author mention any sort of attribution rules. I'm pretty sure short snippets are fine, but what if I copy a handful of classes verbatim (again, no copyright notices, TOS, attribution requests, etc...)? Am I under any legal obligation to the original author?

  • I cannot remove/install software some dependency issue?

    - by Ryuzaki
    I'm having difficulty trying to install/uninstall applications in Ubuntu 12.04 LTS. I have this warning error that appears on my desktop in the form of a red icon with a line through it and it states: An error occurred, please run Package Manager from the right-click menu or apt-get in a terminal to see what is wrong.

  • Social Networks & the Cloud

    - by kellsey.ruppel
    It’s no secret that millions of people are connected to the Internet.

  • Data Source Use of Oracle Edition Based Redefinition (EBR)

    - by Steve Felts
    Edition-based redefinition is a new feature in the 11gR2 release of the Oracle database. It enables you to upgrade the database component of an application while it is in use, thereby minimizing or eliminating down time. It works by allowing for a pre-upgrade and post-upgrade view of the data to exist at the same time, providing a hot upgrade capability. You can then specify which view you want for a particular session.  See the Oracle Database Advanced Application Developer's Guide for further information. There is also a good white paper at Edition Based Definition. Using this feature of the Oracle database does not require any new WebLogic Server functionality. It is set for each connection in the pool automatically by simply specifying SQL ALTER SESSION SET EDITION = edition_name in the Init SQL parameter in the data source configuration. This can be configured either via the console or via WLST (setInitSQL on the JDBCConnectionPoolParams). This SQL statement is executed for each newly created physical database connection.Note that we are assuming that a data source references only one edition of the database. To make use of this feature, you would have an earlier version of the application with a data source that references the earlier EDITION and a later version of the application with a data source that references the later EDITION.   Once you start talking about multiple versions of a WLS application, you should be using the WLS "side-by-side" or "versioned" deployment feature.  See Developing Applications for Production Redeployment for more information.  By combining Oracle database EBR and WLS versioned deployment, the application can be failed over with no downtime, making the combination of features more powerful than either independently. There is a catch - you need to be running with a versioned database and a versioned application initially so then you can switch versions.  The recommended way to version a WLS application is to simply add the "Weblogic-Application-Version" property in the MANIFEST.MF file(you can also specify it at deployment time). The recommended way to configure the data source is to use a packaged data source descriptor that's stored in the ear or war so that everything is self-contained.  There are some restrictions.  You can't use a packaged data source with Logging Last Resource (LLR) - you need to use a system resource.  You can't use an application-scoped packaged data source with EmulateTwoPhaseCommit for the global-transactions-protocol with a versioned application - use a global scope.  See Configuring JDBC Application Modules for Deployment for more details. There's one known problem - it doesn't work correctly with an XA data source (patch available with bug 14075837).
