• Is it reasonable for REST resources to be singular and plural?

  - by Evan

  I have been wondering if, rather than a more traditional layout like this: api/Products GET // gets product(s) by id PUT // updates product(s) by id DELETE // deletes (product(s) by id POST // creates product(s) Would it be more useful to have a singular and a plural, for example: api/Product GET // gets a product by id PUT // updates a product by id DELETE // deletes a product by id POST // creates a product api/Products GET // gets a collection of products by id PUT // updates a collection of products by id DELETE // deletes a collection of products (not the products themselves) POST // creates a collection of products based on filter parameters passed So, to create a collection of products you might do: POST api/Products {data: filters} // returns api/Products/<id> And then, to reference it, you might do: GET api/Products/<id> // returns array of products In my opinion, the main advantage of doing things this way is that it allows for easy caching of collections of products. One might, for example, put a lifetime of an hour on collections of products, thus drastically reducing the calls on a server. Of course, I currently only see the good side of doing things this way, what's the downside?

• What is the good way of sharing specific data between ViewModels

  - by voroninp

  We have IAppContext which is injected into ViewModel. This service contains shared data: global filters and other application wide properties. But there are cases when data is very specific. For example one VM implements Master and the second one - Details of selected tree item. Thus DetailsVm must know about the selected item and its changes. We can store this information either in IAppContext or inside each concerned VM. In both cases update notifications are sent via Messenger. I see pros and cons for any of the approaches and can not decide which one is better. 1st: + explicitly exposed shared proerties, easy to follow dependencies - IAppContxt becomes cluttered with very specific data. 2nd: the exact opposite of the first and more memory load due to data duplication. May be someone can offer design alternatives or tell that one of the variants is objectively superior to the other cause I miss something important?

• OpenGL : Keeping alpha in a render buffer

  - by Cyan

  In my current task, i need to render a texture into a render buffer, in order to work on it (apply special filters) there. The result is then considered a "new texture", which is later displayed. This works fine, except when the texture contains some transparent/semi-transparent parts. My current guess it that, within the render buffer, the texture is "merged" with a kind of "grey background". In this case, it obviously impacts the R,G,B color components of transparent pixels. I've yet to find a way around this. Even manually assigning alpha after the rendering process doesn't save the day for semi-transparent pixels, which RGB are "tainted" by the grey background.

• Mount Bluetooth USB in VirtualBox

  - by GoBrewers14

  I originally asked this question here Python Module PyBluez Error and have narrowed it down to basically I can't get VBox to recognize my bluetooth USB. I'm on a MAC OS X 10.9.2. I've installed VirtualBox as well as the Extension Pack and I've installed Ubuntu Desktop 10.04.4 on the VirtualBox. I've searched several Mac forums and this seems to be a common problem w/o a clear solution. Anyways, the question is how can I get VirtualBox to let Ubuntu recognize my bluetooth USB? I've checked 'Enable USB 2.0 EHCI Controller' and added my two bluetooth devices to the filters list. and when I click here to mount the USB I get this error message... Any ideas? Thanks, John

• Does any CMS natively support something like aquaBrowser/Vufind

  - by nus

  What I'm looking for is to set up a CMS website with a tag cloud/search system where when you click a tag it shows as a search filter, and you get a new tag cloud which only shows tags from the articles that have the primary tag. This should let the user easily include or exclude tags from the search. Also i would like to let the user filter on publication date by using a slider... Check this for an example of how aquabrowser does this (just search for something and play with the tag cloud): http://kidscatalog.columbuslibrary.org It's not perfectly what I want and I don't want to use flash, but I like the concept alot. If something like this does not exist and i might have to code it myself, which cms is most recommended (eg easy to extend, already has tag clouds and search filters,...)

• Are session aware Models a bad thing?

  - by kevtufc

  I'm thinking specifically in Rails here, but I suspect this is a wider question. In a Rails web application I'm using data from the session in models in order that the models know who is logged in. I use this in a method which filters out some data from the database depending on a very simple permissions system. The thing is: using sessions in models in Rails requires a bit of a workaround. It works, but I've a feeling that it's something that I shouldn't be doing and I'm worried there's a big gotcha I'm missing. I suppose the Right Thing To Do would be to return all the data and filter out the not-wanted bits in the controller before passing that to the view, but doing it in the model seems to avoid quite a bit of code duplication and so feels "cleaner." Can anyone tell me why or shouldn't do this? Or that it's not a problem?

• Google Analytics Request URI to Event advanced filter

  - by confidentjohn

  I have a query string attached to a Request URI. Whilst I can see this data within the pages report and it works, I was thinking about setting up an advanced filter to convert the request URI to an Event, with the hope this would clean up my pages report and sit this query with related events in my data. I can see in advanced filters that this is possible, but seems limited to specifying a single event area, so Cat, action or Label, not all 3. Does any one know how I could set up an advanced filter to find any URIs that contain a specific query string, say example below. www.example.com?querystring=123 and convert this into an event, where I can set the Cat, action and label.

• How can I show contextual ads after a user filtered page contents by keyword?

  - by lex82

  I am building a social bookmarking service that is monetized in part by Google Adsense. However, I don't know how to influence how the ads are displayed. I think Google scans my pages and decides itself which ads to show where. Navigation on my site is mainly based on the selection of categories or tags being provided by the users. So after a user filters a list of bookmarks by the tag "SEO", I think I know pretty well what he is looking for. So I am looking for a service that allows me to show contextual ads for these particular keywords. How I can guide Google to show relevant ads? Can you recommend an alternative ad network, that gives me more control?

• Export from EndNote into MySQL database

  - by Tomba

  I would like to export some records from an EndNote (reference management software) library and import into a MySQL database. Does anyone have any experience with this? I've tried creating custom EndNote "output styles" containing either comma-delimited values or even SQL code, but have had mixed results, either because EndNote filters out some characters (like `) or because EndNote doesn't (or I can't work out how to make it) escape text, which might include characters like ' and ". I realize this might be a bit off-topic but any help would be appreciated.

• How do I configure Mercurial to use environment variables in mercurial.ini

  - by Coda

  How can I modify the mercurial.ini file to include an environment variable such as %userprofile%. Specific situation: I am learning to use Mercurial.

The .hgignore file includes filters that that ignore the filenames correctly at commit time. But how can I alter it from being the a literal user to an environment variable $user?

• Would like to create some defaults for my .hgignore files in TortoiseHG/Mercurial

  - by DanM

  I'd like to make it so that every time I create a new repository, certain filters automatically get added to my .hgignore files by default. For example, for C# projects, I would like these to be added: glob:bin/* glob:obj/* Is this possible? How? If it can't be automated, is it at least safe to copy the .hgignore file from one repository to another?

• Maven Assembly Plugin - install the created assembly

  - by Walter White

  I have a project that simply consists of files. I want to package those files into a zip and store them in a maven repository. I have the assembly plugin configured to build the zip file and that part works just fine, but I cannot seem to figure out how to install the zip file? Also, if I want to use this assembly in another artifact, how would I do that? I am intending on calling dependency:unpack, but I don't have an artifact in the repository to unpack. How can I get a zip file to be in my repository so that I may re-use it in another artifact? parent pom <build> <plugins> <plugin> <!--<groupId>org.apache.maven.plugins</groupId>--> <artifactId>maven-assembly-plugin</artifactId> <version>2.2-beta-5</version> <configuration> <filters> <filter></filter> </filters> <descriptors> <descriptor>../packaging.xml</descriptor> </descriptors> </configuration> </plugin> </plugins> </build> Child POM <parent> <groupId>com. ... .virtualHost</groupId> <artifactId>pom</artifactId> <version>0.0.1</version> <relativePath>../pom.xml</relativePath> </parent> <name>Virtual Host - ***</name> <groupId>com. ... .virtualHost</groupId> <artifactId>***</artifactId> <version>0.0.1</version> <packaging>pom</packaging> I filtered the name out.

• WIA Automation for scanner color intent is not working

  I cannot get my Canon Pixma MP150 to scan a color scan from c# code. The following code is resulting in a black and white image, or if I change the value of 6146 to 2 then a grayscale image is created. I would like to be able to have a color scan from code. I know the scanner does color images because I can do one through the xp wizard in "scanners and camera". Can anyone help me figure out what value I am not setting for a color scan. All documentation and examples I can find just say to change the value of 6146.

• Infinite loop using Spring Security - Login page is protected even though it should allow anonymous

This is almost certainly an error. I've tried changing the ROLE_ANONYMOUS to IS_AUTHENTICATED_ANONYMOUSLY, changing the login-page to index.jsp, login.htm, and adding different intercept-url values, but I can't get it so the login page is accesible and security applies to the other pages. What do I have to change to avoid this loop?
