  • Rehosting content from another server

    - by Lana_M
    We have a set of static pages that will augment a customer's existing site. The pages will not reside on the customer's servers for logistical reasons and because we need to maintain control of the content. The plan is for the customer to set up a mod_rewrite rule that will funnel certain types of URLs to a single server-side handler script that will grab the appropriate file from a CDN and just output its content. This illustrates the approach: <?php echo(file_get_contents(str_replace($customer_host, $cdn_host, $_SERVER['REQUEST_URI']))); ?> Can anyone think of pitfalls or offer up a different approach? Is there some way to circumvent a script altogether?

  • Creating an online community - use templates or self-develop?

    - by ican ican
    PHPMotion, Joomla or develop my own? I'm thinking of developing a common interest online community. It will be have UGC, stats, etc.. functionality, and perhaps an online store. Though cost is an issue at this time, I want to be professional and effective. Should I use existing free platform templates, like PHP, Joomla, or should I develop my own? What are the advantages/disadvantages of either option? As a rough estimate, how much will it cost me to develop and manage my own? And how long will it take. In general what should I be careful about on this journey?

  • How can IIS 7.5 have the error pages for a site reset to the default configuration?

    - by Sn3akyP3t3
    A mishap occurred with web.config to accommodate a subsite existing. I made use of “<location path="." inheritInChildApplications="false">”. Essentially it was a workaround put in place for nested web.config files which was causing a conflict. The result was that error pages were not being handled properly. Error 500 was being passed to the client for every type of error encountered. Removal of the offending inheritInChildApplications tag from the root web.config restored normal operations of most of the error handling, but for some reason error 503 is a correct response header, but the IIS server is performing the custom actions for error 403.4 which is a redirect to https. I'm looking to restore defaults for error pages so that the behavior once again is restored. I then can re-add customizations for the error pages.

  • How do I install Ubuntu to a USB key?

    - by badp
    If you are hurrying to reply, System ? Administration ? StartUp Disk Creator -- no, that's not what I'm talking about. I want to try Ubuntu 11.04's Unity without touching my existing Ubuntu install. To do this, I need to install the nVidia drivers first (sigh). To do this, I need changes to persist a reboot. To do this, I need to really install Ubuntu on a USB key. How do you do that? What I tried I tried to make a USB key from Testdrive, then boot from it, then choose "Install Ubuntu." The installer refused to install to the installation media itself. I tried, from my installed copy of Ubuntu: sudo kvm /dev/sdb --cdrom .cache/testdrive/iso/ubuntu_natty-desktop-i386.iso ...but the installer didn't detect the disk properly.

  • Highlighting new rows in ADF Table

    - by Sireesha Pinninti
    About This article explains how to hightlight newly inserted rows in an ADF Table without writing any extra java/javascript code.IntroductionSometimes we may wish to give more clarification to the end user by differentiating between newly inserted rows and the existing rows(i.e the rows from DB) in a table by highlighting new rows in different color as in the figure shown below. SolutionWe can achieve the same by giving following EL to inlineStyle property of every column inside af:table: #{row.row.entities[0].entityState == 0?'background-color:#307D7E;':''}ExplanationHere is the explanation for row.row.entities[0].entityState given inside EL which returns the state of the row(i.e, New, Modified, Unmodified, Initialized etc.)row - Refers to a tree node binding(instance of FacesCtrlHierNodeBinding) at runtimerow.row - Refers to an instance of row that the tree node is based onrow.row.entities[0] - Gets the Entity row at zeroth index. In most of the cases, the table will be based on single entity. If your table is based on multiple entities then the index needs to be given accordingly.row.row.entities[0].entityState - Gets Entity Object's current Entity-state in the transaction.(0 - New, Modified - 2, Unmodified - 1, Initialized - -1,  etc.,)

  • Personal/career objectives tracker

    - by scottyab
    Looking for a simple, clean and easy to use personal/career objectives tracker for my team of ~10 developers something like what remember the milk is for tasks. At the moment I track these in a google doc, but ideally like a system where I can browse the teams objectives, add a team objective and it automatically appear on members personal objectives. Also where team members can add/manage their own objectives, browse colleges public/team objectives. Ideally it would also have option for people to add personal out side of work objectives for personal dev projects. Anyone used a tool to do this? our a combination of existing tools like gdocs, rtm?

  • Microsoft Sync. Framework with Azure on iOS

    - by Richard Jones
    A bit of a revelation this evening. I discovered something obvious, but missing from my understanding of the brilliant iOS example that ships with the Sync. Framework 4.0CTP It seems that on the server side if a record is edited, correctly only the fields that are modified gets sent down to your device (in my case an iPad). I was previously just blindly assuming that I'd get all fields down. I modified my Xcode population code (based on iOS sample) as follows: + (void)populateQCItems: (id)dict withMetadata:(id)metadata withContext:(NSManagedObjectContext*) context { QCItems *item = (QCItems *)[Utils populateOfflineEntity:dict withMetadata:metadata withContext:context]; if (item != nil) // modify new or existing live item { if ([dict valueForKey:@"Identifier"]) // new bit item.Identifier = [dict valueForKey:@"Identifier"]; if ([dict valueForKey:@"InspectionTypeID"]) // new bit item.InspectionTypeID = [dict valueForKey:@"InspectionTypeID"]; [item logEntity]; } } I hope this helps someone else; as I learnt this the hard way.

  • how can I contact Google about a domain misuse?

    - by questy
    I was trying to add a newer domain of mine to my existing Google Apps account with an already set primary domain. Google Apps then returns the message that the domain is already in use by another account. I tried finding a way to contact Google, but they have a wall up preventing anyone with an original Apps account from calling them. There's a help page saying to try retrieving the password, but how is that even possible? I don't know the email address of the owner of the Apps account using my domain, and I don't know his/her name on the account, so I can't complete the form for retrieving any of the information. Google Productforums is always a dead end. Does anyone here know how to force a removal of a domain on Google Apps from someone that doesn't own it?

  • Develop JavaScript API to expose web services [closed]

    - by Apps
    We are planning to develop a JavaScript API to expose some of our J2EE based services. We are doing this keeping Google Maps API in mind. Can someone please suggested where we should start and the approaches that we need to follow to create a useful and extensible JavaScript API? These are the things that we are considering to achieve. It should be very simple for others to use our API. We feel Google Maps API is like that. We should be able to release the updates of the APIs without affecting the existing implementations. We should have enough security measures so that not all can use these services. Please suggest us if there are any books that can guide us through. Any suggestion will be greatly helpful for us. Please let me know if my question is not clear or you need any further information.

  • Intercepting the Unity logout

    - by qbi
    I want to copy some data from another machine to a local computer on a regular basis. At the moment I'm researching different solutions and try to find the one which fits best. Basically I want to open a network connection (or use an existing one), make a VPN connection and start a rsync process. This should be done on every logout of my desktop session or on shutdown. One possible solution might be to somehow intercept the Unity shutdown and execute a script. So is there a possibility to execute a script on GNOME/Unity shutdown? I'm aware that you can do it on system shutdown. How can I do this?

  • Mount file system path as encrypted?

    - by Sebi
    I know how to mount an encrypted ext4 partition. However, now I want to do the opposite. I want to mount a folder of an existing partition somewhere else in my filesystem, but when accessing it, files should get encrypted using AES256. Is that possible? Here an example: I have a folder containing some images 1.jpg, 2.jpg, 3.jpg, etc. I want to mount this folder in another location so that the content of the images are encrypted. Filenames shouldn't change. Background: I want to synchronise my image folder to a cloud storage, but I want to encrypt the files before upload. The tools provided by the cloud provider don't support client side encryption. Therefore, I want to use the tools on a folder only containing encrypted data.

  • What freely available software is equipped for editing PDF Bookmarks?

    - by Brenton Horne
    I know of PDFMod, which I rather like except it has one flaw, I can't seem to be able to add bookmarks before pre-existing bookmarks (see the attached image if this is unclear). I've looked at this question: - Which programs can I use to edit PDF files? That question does not deal specifically with bookmark editing, neither does it specify which software is freely available and which isn't. I should add that I'm incompetent when it comes to installing software so any software that's not available in the Software Centre requires you to detail exactly how I'm meant to install it. Plus, I would specifically like a software that can handle large (like 80 MB) PDF files without lagging like crazy or closing down.

  • How important is to avoid name collisions between libraries belonging to different domains?

    - by Sergio
    I have written a small open source Java library for facilitating conversions between different types of objects (in the style of Google's gson, but quite more general). It seems to me that a nice natural name for my library is JConverter, after browsing in the web to see if another library with the same name already exists, I found a library with the same name for Joomla. My concrete question is: How important is to avoid naming collisions when creating an open source library if an existing library with the chosen name already exists in a complete different domain ? (in my concrete case, these are libraries even implemented for different languages).

  • Restoring Grub after Kubuntu installation

    - by justquestions
    I installed Kubuntu on top of my existing Ubuntu 12.04 (64 bit) installation. During Kubuntu installation, I chose lightdm as my default display manager (instead of kdm). Now after rebooting, the Grub has a new color (gray instead of default purplish) and the screen while booting is gray (instead of purplish). I am curious if it is possible to change this grub behavior without removing Kubuntu. I did find a lot of discussion about modifying grub themes but they were not very useful because I do not know what is the default unity grub theme. I did reinstall grub but it didn't change anything. I tried the Grub Customizer but couldn't succeed. Thanks in advance!

  • Oracle Service Contracts – Calculate Estimated Tax with Higher Accuracy

    - by LuciaC-Oracle
    On a Service Contract the tax rate and its effectivity can change over the contract duration.  Hence, service organizations need to provide an accurate picture of the estimated tax that the customer might end up paying.  Prior to Release 12.1.3+, the Oracle Service Contracts application calculated the estimated tax based on the line/ sub line start date.  With Release 12.1.3+ (via Patch 16601269:R12.OKS.B) , new functionality provides users with an option to calculate tax at contract billing schedule level, thereby considering the changes in tax rate effectivity at that level.A new profile option 'OKS: Calculate Tax at Schedule' has been introduced which can be used to control whether the existing or new functionality is used.  If the profile is set to 'Yes' the application calculates tax at the billing schedule level for all lines/ sub lines.  For more details on the implementation steps and functionality, please refer to Doc ID 1676700.1: Oracle Service Contracts – How To Calculate Estimated Tax with Higher Accuracy.

  • "Best fit" to avoid reuse of object instances in a collection

    - by Simon
    Imagine I have a collection of object instances which represent activities for a user to undertake. Dependent on user attributes, I have to randomly select instances to present activities to the user. For some users, I need to present more activities to them than there are available activities in which case, I want to use the following algorithm. If all available activities have already been presented to the user, then re-select a "used" activity, selecting the earliest presented activity ordered by frequency of use. In other words, try to reduce repetition and where repetition is unavoidable, use the instances which have been repeated less often and were presented furthest back in time. Before I go on to code that algorithm, I wondered if there is some existing pattern I can re-use? [EDIT] "Furthest back in time" is not relevant as I will pass the algorithm an ordered collection of used instances where the first entry is the first presented.

  • How to design a game engine in an object-oriented language?

    - by chuzzum
    Whenever I try and write a game in any object-oriented language, the first problem I always face (after thinking about what kind of game to write) is how to design the engine. Even if I'm using existing libraries or frameworks like SDL, I still find myself having to make certain decisions for every game, like whether to use a state machine to manage menus, what kind of class to use for resource loading, etc. What is a good design and how would it be implemented? What are some tradeoffs that have to be made and their pros/cons?

  • Is deserializing complex objects instead of creating them a good idea, in test setup?

    - by Chris Bye
    I'm writing tests for a component that takes very complex objects as input. These tests are mixes of tests against already existing components, and test-first tests for new features. Instead of re-creating my input objects (this would be a large chunk of code) or reading one from our data store, I had the thought to serialize a live instance of one of these objects, and just deserialize it into test setup. I can't decide if this is a reasonable idea that will save effort in long run, or whether it's the worst idea that I've ever had, causing those that will maintain this code will hunt me down as soon as they read it. Is deserialization of inputs a valid means of test setup in some cases? To give a sense of scale of what I'm dealing with, the size of serialization output for one of these input objects is 93KB. Obtained by, in C#: new BinaryFormatter().Serialize((Stream)fileStream, myObject);

  • Should an object know its own ID?

    - by xenoterracide
    obj.id seems fairly common and also seems to fall within the range of something an object could know about itself. I find myself asking why should my object know its own id? It doesn't seem to have a reason to have it? One of the main reason for it existing is retrieve it, and so my repositories need to know it, and thus use it for database interaction. I also once encountered a problem where I wanted to serialize an object to JSON for a RESTful API where the id did not seem to fit in the payload, but only the URI and including it in the object made that more difficult. Should an object know it's own id? why or why not?

  • Is the phrase "never reinvent the wheel" suitable for students?

    - by Gnijuohz
    I find myself constantly running into this expression "don't reinvent the wheel" or "never reinvent the wheel" when I ask some questions on SO. They tell you to use some frameworks or existing packages. I know where this attitude is coming from since it's unwise to waste time on something others have already solved. Or it that so? As a student, I find by using some code others wrote to solve my problem I can't learn as much as I'd like to, and I gain less insight. And sometimes I think that phrase is mainly for working programmers facing deadlines and not for students like me. Is it that bad to "reinvent the wheel"? Maybe I'm thinking it wrong? Maybe there is a way I can avoid reinventing the wheel and at the same time learn a lot?

  • Building a Repository Pattern against an EF 5 EDMX Model - Part 1

    - by Juan
    I am part of a year long plus project that is re-writing an existing application for a client.  We have decided to develop the project using Visual Studio 2012 and .NET 4.5.  The project will be using a number of technologies and patterns to include Entity Framework 5, WCF Services, and WPF for the client UI.This is my attempt at documenting some of the successes and failures that I will be coming across in the development of the application.In building the data access layer we have to access a database that has already been designed by a dedicated dba. The dba insists on using Stored Procedures which has made the use of EF a little more difficult.  He will not allow direct table access but we did manage to get him to allow us to use Views.  Since EF 5 does not have good support to do Code First with Stored Procedures, my option was to create a model (EDMX) against the existing database views.   I then had to go select each entity and map the Insert/Update/Delete functions to their respective stored procedure. The next step after I had completed mapping the stored procedures to the entities in the EDMX model was to figure out how to build a generic repository that would work well with Entity Framework 5.  After reading the blog posts below, I adopted much of their code with some changes to allow for the use of Ninject for dependency injection.http://www.tcscblog.com/2012/06/22/entity-framework-generic-repository/ http://www.tugberkugurlu.com/archive/generic-repository-pattern-entity-framework-asp-net-mvc-and-unit-testing-triangle IRepository.cs public interface IRepository : IDisposable where T : class { void Add(T entity); void Update(T entity, int id); T GetById(object key); IQueryable Query(Expression> predicate); IQueryable GetAll(); int SaveChanges(); int SaveChanges(bool validateEntities); } GenericRepository.cs public abstract class GenericRepository : IRepository where T : class { public abstract void Add(T entity); public abstract void Update(T entity, int id); public abstract T GetById(object key); public abstract IQueryable Query(Expression> predicate); public abstract IQueryable GetAll(); public int SaveChanges() { return SaveChanges(true); } public abstract int SaveChanges(bool validateEntities); public abstract void Dispose(); } One of the issues I ran into was trying to do an update. I kept receiving errors so I posted a question on Stack Overflow http://stackoverflow.com/questions/12585664/an-object-with-the-same-key-already-exists-in-the-objectstatemanager-the-object and came up with the following hack. If someone has a better way, please let me know. DbContextRepository.cs public class DbContextRepository : GenericRepository where T : class { protected DbContext Context; protected DbSet DbSet; public DbContextRepository(DbContext context) { if (context == null) throw new ArgumentException("context"); Context = context; DbSet = Context.Set(); } public override void Add(T entity) { if (entity == null) throw new ArgumentException("Cannot add a null entity."); DbSet.Add(entity); } public override void Update(T entity, int id) { if (entity == null) throw new ArgumentException("Cannot update a null entity."); var entry = Context.Entry(entity); if (entry.State == EntityState.Detached) { var attachedEntity = DbSet.Find(id); // Need to have access to key if (attachedEntity != null) { var attachedEntry = Context.Entry(attachedEntity); attachedEntry.CurrentValues.SetValues(entity); } else { entry.State = EntityState.Modified; // This should attach entity } } } public override T GetById(object key) { return DbSet.Find(key); } public override IQueryable Query(Expression> predicate) { return DbSet.Where(predicate); } public override IQueryable GetAll() { return Context.Set(); } public override int SaveChanges(bool validateEntities) { Context.Configuration.ValidateOnSaveEnabled = validateEntities; return Context.SaveChanges(); } #region IDisposable implementation public override void Dispose() { if (Context != null) { Context.Dispose(); GC.SuppressFinalize(this); } } #endregion IDisposable implementation } At this point I am able to start creating individual repositories that are needed and add a Unit of Work.  Stay tuned for the next installment in my path to creating a Repository Pattern against EF5.
