  • Good way to manage blog/news? [closed]

    - by DavidScherer
    I really don't want to undertake handling blog/news posts within a site I'm working on and would much rather use some other software that's fairly bare-bones that will manage the posts and then I can just pull posts from the DB or an API. Does anyone have any experience with a nice, lightweight OS Blog type software that has either an API or is basic enough to simply pull Data from the database? I really only need the software for managing, I plan to display all the posts programatically through MVC.

  • Stairway to T-SQL DML Level 5: The Mathematics of SQL: Part 2

    Joining tables is a crucial concept to understanding data relationships in a relational database. When you are working with your SQL Server data, you will often need to join tables to produce the results your application requires. Having a good understanding of set theory, and the mathematical operators available and how they are used to join tables will make it easier for you to retrieve the data you need from SQL Server.

  • Help identify the pattern for reacting on updates

    - by Mike
    There's an entity that gets updated from external sources. Update events are at random intervals. And the entity has to be processed once updated. Multiple updates may be multiplexed. In other words there's a need for the most current state of entity to be processed. There's a point of no-return during processing where the current state (and the state is consistent i.e. no partial update is made) of entity is saved somewhere else and processing goes on independently of any arriving updates. Every consequent set of updates has to trigger processing i.e. system should not forget about updates. And for each entity there should be no more than one running processing (before the point of no-return) i.e. the entity state should not be processed more than once. So what I'm looking for is a pattern to cancel current processing before the point of no return or abandon processing results if an update arrives. The main challenge is to minimize race conditions and maintain integrity. The entity sits mainly in database with some files on disk. And the system is in .NET with web-services and message queues. What comes to my mind is a database queue-like table. An arriving update inserts row in that table and the processing is launched. The processing gathers necessary data before the point of no-return and once it reaches this barrier it looks into the queue table and checks whether there're more recent updates for the entity. If there are new updates the processing simply shuts down and its data is discarded. Otherwise the processing data is persisted and it goes beyond the point of no-return. Though it looks like a solution to me it is not quite elegant and I believe this scenario may be supported by some sort of middleware. If I would use message queues for this then there's a need to access the queue API in the point of no-return to check for the existence of new messages. And this approach also lacks elegance. Is there a name for this pattern and an existing solution?

  • Critical Patch Updates During EBS 11i Exception to Sustaining Support Period

    - by Elke Phelps (Oracle Development)
    As previously blogged in the EBS 11i and 12.1 Support Timeline Changes entry, two important changes to the Oracle Lifetime Support policies were announced at Oracle OpenWorld 2012 - San Francisco.  These changes affect E-Business Suite Releases 11i and 12.1. Critical Patch Updates for EBS 11i during the Exception to Sustaining Support Period You may be wondering about the availability of Critical Patch Updates (CPU) for EBS 11i during the Exception to Sustaining Support period.  The following details the E-Business Suite Critical Patch Update support policy for EBS 11i during the Exception to Sustaining Support period: Oracle will continue to provide CPUs containing critical security fixes for E-Business Suite 11i.  CPUs will be packaged and released as as cumulative patches for both ATG RUP 6 and ATG RUP 7. As always, we try to minimize the number of patches and dependencies required for uptake of a CPU; however, there have been quite a few changes to the 11i baseline since its release.  For dependency reasons the 11i CPUs may require a higher number of files in order to bring them up to a consistent, stable, and well tested level. EBS 11i customer will continue to receive CPUs up to and including the October 2014 CPU. Where can I learn more? There are two interlocking policies that affect the E-Business Suite:  Oracle's Lifetime Support policies for each EBS release (timelines which were updated by this announcement), and the Error Correction Support policies (which state the minimum baselines for new patches). For more information about how these policies interact, see: Understanding Support Windows for E-Business Suite Releases What about E-Business Suite technology stack components? Things get more complicated when one considers individual techstack components such as Oracle Forms or the Oracle Database.  To learn more about the interlocking EBS+techstack component support windows, see these two articles: On Apps Tier Patching and Support: A Primer for E-Business Suite Users On Database Patching and Support: A Primer for E-Business Suite Users Where can I learn more about Critical Patch Updates?The Critical Patch Update Advisory is the starting point for relevant information. It includes a list of products affected, pointers to obtain the patches, a summary of the security vulnerabilities, and links to other important documents.  Related Articles EBS 11i and 12.1 Support Timeline Changes Frequently Asked Questions about Latest EBS Support Changes Extended Support Fees Waived for E-Business Suite 11i and 12.0

  • How to explain bad software to non-technical people?

    - by mtutty
    In discussing software development with non-technical people (customers, business owners, project sponsors, etc.), I often resort to analogies and metaphors. It's relatively easy and effective to use a "house" or other metaphor for describing the size and complexity of new development. However, we often inherit someone else's code or data, and this approach doesn't seem to hold up as well when trying to explain why we're gutting something that already seems to work. Of course we can point to cycle time and cost to be saved in the future but this generally means nothing to business folks. I know doctors can say "just take this pill," but I'm not sure that software devs have the same authority. Ideas? EDIT: Let me add a bit to the discussion. The specific project I'm talking about has customers that don't realize (or care) about specific aspects of the system we're retiring (i.e., they think it was just fine): The system would save a NEW RECORD every time someone updated a field The system contained tables for reference data. These tables had new records added every day, even though they were duplicates of previous records. And there was no way to tie the reference data used for a particular case at the time it was closed. This is like 99% of the data in the old system. The field NAMES also have spaces, apostrophes and other inappropriate characters in them, making everything harder to work with. In addition to the incredible amount of duplicate data, they have around 1000 XLS files with data they want added to the system. Previously, they would do a spreadsheet for each case in the database, IN ADDITION TO what they typed into the database. Getting rid of this old, unneeded information and piping in the XLS data comprises about 80% of the total project effort, and was not something we could accurately predict. I'm trying to find a concrete way to describe how bad this thing was, mostly so that the customer will understand why the migration process has been so time-consuming. The actual coding was done pretty quickly and the new system works fine, but without the old data they won't be happy. Sorry to get into the weeds, but most of the answers I've seen so far are pretty basic scope/schedule/cost things. I've been doing this for 15 years, so this really is more of a reflective, philosophical question - but without some of the details it can be difficult to really appreciate the awful beauty of this problem.

  • 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}”
