I realize GPUImage has been well documented and there's a lot of instructions on how to use it on the main github page. However, it fails to explain what a filter chain is - what's addTarget? What's missing is a simple enough diagram showing what needs to be added to what. Is it always GPUImageView (source?) -> add target -> [filter]? I'm sorry if this sounds daft, but I fail to follow the correct sequence given there are so many ways of using it. To me, it sounds like you're connecting it the other way round (such as saying: Connect the socket to the TV). Why not add filter to the source? I'm trying to use it but I get lost in all the addTargets. Thanks!
You can think of it as a series of inputs and outputs. Look in the GPUImage framework project to see which are inputs (typically filters) and which are outputs (imageview, moviewriter, etc..). Every target effects the next target in the chain.
Example:
GPUImageMovie -> GPUImageSepiaFilter -> GPUImageMovieWriter
A movie will be sent to the sepia filter that will perform its job, the movie with a sepia filter applied will be sent to the movie writer, then the movie writer will export a movie with a sepia filter applied.
To help visualize what's going on, any node editor program typically uses this scheme. Think of calling addTarget: as one of the connections in the attached image.
A google image search for Node Editor will give you plenty of other image to help picture what adding targets does.

Goal: View multiple scopes(file tree) at once.
I'm modifying a little old web node application, the view folder and logic handling are written in different places, but I need to see each other.
So, I would like to have multiple file trees in the same project for easy navigation.
However, since the folders are so far apart from each other, I set up a scope and try to switch between them each time.
Sorry, my English is not very good, so I use a little translation. I'm attaching a picture just in case.
Thank you.
I was able to find a few solutions.
It is the Favorites window.
Maybe the scope is not available, but I was able to increase the number of project views to two.
I can't open more than three of them, so if there is a convenient way to do this, please let me know.
Thank you.

I'm building a single page application in Elm and was having difficulty deciding how to split my code in files.
I ended up splitting it using 1 module per page and have Main.elm convert the Html and Cmd emitted by each page using Cmd.map and Html.map.
My issue is that the documentation for both Cmd.map and Html.map says that :
This is very rarely useful in well-structured Elm code, so definitely read the section on structure in the guide before reaching for this!
I checked the only 2 large apps I'm aware of :
elm-spa-example uses Cmd.map (https://github.com/rtfeldman/elm-spa-example/blob/cb32acd73c3d346d0064e7923049867d8ce67193/src/Main.elm#L279)
I was not able to figure out how https://github.com/elm/elm-lang.org
deals with the issue.
Also, both answers to this stackoverflow question suggest using Cmd.map without second thoughts.
Is Cmd.map the "right" way to split a single page application in modules ?
I think sometimes you just have to do what's right for you. I used the Cmd.map/Sub.map/Html.map approach for an application I wrote that had 3 "pages" - Initializing, Editing and Reporting.
I wanted to make each of these pages its own module as they were relatively complicated, each had a fair number of messages that are only relevant to each page, and it's easier to reason about each page independently in its own context.
The downside is that the compiler won't prevent you from receiving the wrong message for a given page, leading to a runtime error (e.g., if the application receives an Editing.Save when it is in the Reporting page, what is the correct behavior? For my specific implementation, I just log it to the console and move on - this was good enough for me (and it never happened anyway); Other options I've considered include displaying a nasty error page to indicate that something horrible has happened - a BSOD if you will; Or to simply reset/reinitialize the entire application).
An alternative is to use the effect pattern as described extensively in this discourse post.
The core of this approach is that :
The extended Effect pattern used in this application consists in definining an Effect custom type that can represent all the effects that init and update functions want to produce.
And the main benefits :
All the effects are defined in a single Effect module, which acts as an internal API for the whole application that is guaranteed to list every possible effect.
Effects can be inspected and tested, not like Cmd values. This allows to test all the application effects, including simulated HTTP requests.
Effects can represent a modification of top level model data, like the Session 3 when logging in 3, or the current page when an URL change is wanted by a subpage update function.
All the update functions keep a clean and concise Msg -> Model -> ( Model, Effect Msg ) 2 signature.
Because Effect values carry the minimum information required, some parameters like the Browser.Navigation.key are needed only in the effects perform 3 function, which frees the developer from passing them to functions all over the application.
A single NoOp or Ignored String 25 can be used for the whole application.
I am new to writing intellij plugins, so I apologize in advance if my question might be a bit unclear.
I know that (live) code inspections are achieved via Annotators or LocalInspectionTools. I also know there is an API to write a custom Annotator or Inspection tool and I have seen several examples.
What I do not know (my question): is there a manager/helper/"global inspector" that can provide me with the results of an existing code annotator/inspection process (done by the IDE's plugins or by some 3rd party plugin)?
For instance: I do not want to write a custom Lint annotator/inspection plugin for WebStorm. One can configure JSLint/JSHint inside WebStorm settings. The results of the live inspection can be seen over the current file/current open editor.
I would like to get the results of this live inspection, that occurs in the current open editor (inside my own custom code). For this I am interested in the API to get this annotator/inspector and/or the results it provides.
(I apologize for maybe using annotator and inspection terms in a confusing manner)
If there is another question (which I could not find) that duplicates what I have asked above, please re-direct me.
Thank you in advance!
Andrei.
Unfortunately regular annotating process for the linters is asynchronous so you cannot get the annotation results directly (by calling 'Manager' method).
You can create instances of JSLintInspection, JSHintInspection, etc. and call #createVisitor().visit(File) method but the operation is very slow and you must call it outside of AWT thread.
Also you can try to run the method com.intellij.codeInsight.daemon.impl.DaemonCodeAnalyzerEx#processHighlights but as I mentioned above the annotation results for linters can be not available (or outdated)
I am thinking of making a new logic brick to contribute or 10, but need to get a template/idea of where to start, I want to make a 6dof actuator and sensor first, that can trigger based on rotation targets or distance limits etc, and a actuator that can remove or change a 6dof target to a new position or object and position,
I am making a open source 3d puzzle game with limited ads in game, but need to make a few logic bricks, for me and the community....
There are no coding tutorials regarding BGE Game logic that I'm aware of, but here are some pointers for the code:
The game logic parts are mostly in:
https://svn.blender.org/svnroot/bf-blender/trunk/blender/source/gameengine/GameLogic/
You'll see that sensors implement the ISensor interface. Browse through a few different sensors to see how they work. Blender has NDOF device support, so NDOF events already exist (get handled by our GHOST layer: https://svn.blender.org/svnroot/bf-blender/trunk/blender/intern/ghost/intern/GHOST_NDOFManager.h ). You could create a new manager like the mouse manager (see the gamelogic directory for the different managers ).
With this information you should be able to get started. Read the existing code carefully, you'll be able to find what you need.
You can use this commit Mouse actuator commit as your template to add a new actuator.
This is my first time asking a question here so, be nice;p .. I'm working with Magento (and Zend Framework) for the first time and I'm trying to build a custom grid that will populate based off of a manually written query. I'm trying to extend the Mage_Core_Model_Mysql4_Collection_Abstract to allow a query to be loaded into it and then parse the select fields in the extended Grid class to make it dynamic... Is this even possible or am I beating a dead horse? I've been at it for a week now and I'm not getting anywhere. The problem seems to be that inside the __Model_mysql4_Collection class has to be initialized with a resource model using _init() in the constuct
As a learning exercise use the module creator to make an admin grid page and see how that is done. Or even modify it's output to get what you need.
There will be a grid container block, a grid block (with _prepareCollection and _prepareColumns methods), a model, a resource model (representing a single record) and a collection resource model (representing several records).
Providing your own _init methods shouldn't be any sort of problem. Perhaps you'd like to post your config.xml and code so far as a pastebin or something.
