1/ decentralization is a myth. we use "decentralized" without any specificity as to what that actually means. let's untangle the idea of decentralization. i developed a basic grid that breaks it down at the protocol, network, and app layer (dated april 2018)

Measuring centralization can be an informative academic exercise, but IMO the only way to know if a network is sufficiently decentralized is to attack it. If it can withstand attacks from nation states, it's sufficiently decentralized.

Piccolo2D in Comparison
Why should you use Piccolo2D and which version should you use? This section will cover the differences between Piccolo2D.Java, Piccolo2D.NET, and PocketPiccolo2D.NET. In addition, there will be discussions of the differences between Piccolo2D and Jazz (our previous toolkit) and how Piccolo2D relates to other available toolkits.Piccolo2D.Java, Piccolo2D.NET and PocketPiccolo2D.NET
There three versions of Piccolo2D: Piccolo2D.Java, Piccolo2D.NET, and PocketPiccolo2D.NET. They contain the same core functionality with a few differences. We will examine those differences here.
Languages, Libraries and IDEs
Piccolo2D.Java is written in 100% java and relies on the Java2D API for graphics rendering. Applications built on Piccolo2D.Java will run anywhere java will run (including Windows, Mac OS X, Linux and Solaris). The recommended development environment for Piccolo2D.Java is Eclipse, although it is possible to use Piccolo2D.Java without an IDE.
Piccolo2D.NET, on the other hand, is written in C# and relies on the GDI+ API for graphics rendering. It runs on platforms that support the .NET Framework. However, currently only Windows machines implement the Common Language Runtime (CLR). So, If you really want your application to be cross-platform you should use Piccolo2D.Java. On the other hand, the advantage of using Piccolo2D.NET is that it will allow you to easily integrate advanced 2D graphics and zooming with standard Windows application code and platform-specific features. The recommended development environment for Piccolo2D.NET is Visual Studio.NET.
PocketPiccolo2D.NET is also written in C#. It runs on platforms that support the .NET Compact Framework (including Pocket PCs, Pocket PC Phones, Smart Phones, and Windows CE.NET devices). There is no equivalent to GDI+ for the Compact Framework. Thus, PocketPiccolo2D.NET is limited by the primitive drawing routines available through the Compact Framework. See the Features section for more details. As with Piccolo2D.NET, the recommended development environment for PocketPiccolo2D.NET is Visual Studio.NET.
Below is a chart the summarizes the differences outlined above.
| Piccolo2D Version Differences | Piccolo2D.Java | Piccolo2D.NET | PocketPiccolo2D.NET |
|---|---|---|---|
| Language | Java | C# | C# |
| Underlying Framework | Java 2 | .NET Framework | .NET Compact Framework |
| Graphics Renderer | Java2D | GDI+ | Limited GDI |
| IDE of Choice | Eclipse | Visual Studio.NET | Visual Studio.NET |
Speed/Memory
In terms of both speed and memory usage, Piccolo2D.Java and Piccolo2D.NET are comparable. While earlier versions of .NET had slower image rendering performance than Java, we have not done any direct comparisons in several years. In practice, we find Java and C# to have similar rendering performance.
Since performance is critical in a graphics toolkit, we provide framework support for plugging in other more powerful renderers. The current release of Piccolo2D.NET includes an implementation of a Direct3D renderer package. For better performance with Piccolo2D.Java, you can use Agile2D, which includes a pluggable OpenGL implementation of Java2D.
PocketPiccolo2D.NET is our first alpha release targeting the .NET Compact framework. As such, it has not yet been optimized for performance.
Features
Piccolo2D.Java and Piccolo2D.NET support virtually the same feature set. This makes it very easy port code from one version to the other. There are however a couple exceptions:
- Transparency - Piccolo2D.NET does not have built-in support for transparency since .NET does not provide a mechanism to set a global alpha composite. You can of course still use transparent fills on nodes.
- PStyledText - This is a node used to render styled text data at various magnitudes. It is available in Piccolo2D.Java, but not Piccolo2D.NET
- PStyledTextEventHandler - This is an event handler that places a text editor on the screen when a user clicks on a PStyledText node, in order to edit the underlying text. It is available in Piccolo2D.Java, but not Piccolo2D.NET.
- PLine - This is an implementation of a line node, very similar to PPath, that was submitted by a Piccolo2D user. It is available in Piccolo2D.Java, but not Piccolo2D.NET. However, if someone ports and submits a Piccolo2D.NET version we will include it in the source.
- SWT Package - This is a set of classes to help integrate Piccolo2D code into the Eclipse development environment. It is available in Piccolo2D.Java, but not Piccolo2D.NET.
- PFixedWidthStroke - This is stroke class that always has a fixed width on screen, even when the canvas view is zoomed. It is available in Piccolo2D.Java, but not Piccolo2D.NET since there is no simple way to implement a Pen in .NET.
- Piccolo2DDirect3D - This is an implementation of Piccolo2D that uses a Direct3D renderer. It available in Piccolo2D.NET, but not Piccolo2D.Java. However, you can use Agile2D to plug in an OpenGl renderer for Piccolo2D.Java.
- Serialization Surrogates - These are several classes that define how to serialize certain types, to avoid duplicating serialization code. These are available in Piccolo2D.NET, but not Piccolo2D.Java. Piccolo2D.Java uses utility methods to achieve the same effect.
- PControl - This is a PNode wrapper for standard controls, allowing you to embed existing widgets (i.e. buttons, textboxes, etc.) in the scene-graph. It is available in Piccolo2D.NET, but not Piccolo2D.Java
- PControlEventHandler - This is an event handler that implements focused based navigation for PControl nodes. It is available in Piccolo2D.NET, but not Piccolo2D.Java
Just as the .NET Compact Framework is a subset of the .NET Framework, PocketPiccolo2D.NET is a subset of Piccolo2D.NET. It has the same core features: hierarchical transformable objects, animation, event handling and efficiency mechanisms. But, some features of the desktop versions are not available:
- High Quality Rendering - This refers to aliasing and other techniques that improve the quality of the rendering. These optimizations are not available in PocketPiccolo2D.NET since they are not supported by the Compact Framework.
- Transparency - This is unavailable in PocketPiccolo2D.NET since the Compact Framework does not support transparency.
- Rotation - This is unavailable in PocketPiccolo2D.NET since the Compact Framework does not support rotation.
- PPath - This is a graphical path node in the desktop versions of Piccolo2D. In Piccolo2D.Java, PPath wraps the GeneralPath object and in Piccolo2D.NET, it wraps the GraphicsPath object. Since there is no equivalent class to wrap in the Compact Framework, PPath is very limited.
API
The APIs for the various versions of Piccolo2D will all feel similar. In fact, the PocketPiccolo2D.NET API is mostly identical to the Piccolo2D.NET API, except that some of the classes and methods of the desktop version are unavailable. There are also some differences between Piccolo2D.NET and Piccolo2D.Java that reflect an effort to support the individual style guidelines and language constructs of Java and C#.
Method names, for example, begin with a lower-case letter in Piccolo2D.Java and an
upper-case letter in both Piccolo2D.NET and PocketPiccolo2D.NET. For example, the method
that animates a node from it's current position and size to a new position and size is
animateToBounds()
in Piccolo2D.Java and AnimateToBounds()
in
Piccolo2D.NET and PocketPiccolo2D.NET.
Member attributes are also accessed differently in each API. For example, in Piccolo2D.Java, attributes are accessed via get/set methods. But, Piccolo2D.NET and PocketPiccolo2D.NET take advantage of language supported Properties. For example, to access the bounds of a node in each version you would do the following:
| //Piccolo2D.Java | //Piccolo2D.NET and PocketPiccolo2D.NET |
node.getBounds() |
node.Bounds |
The APIs also differ in terms of the underlying types they use. Often the Java and
.NET names of equivalent classes are different. For example, Java has Paint and Stroke
classes whereas .NET has Brush and Pen classes. Another example is the affine transform
type, which is called AffineTransform in java and Matrix in .NET. The names of Piccolo2D
methods also reflect these differences. For example, the method to animate a node to an
arbitrary affine transform is animateToTransform()
in Piccolo2D.Java and
AnimateToMatrix()
in Piccolo2D.NET and PocketPiccolo2D.NET.
One very important distinction related to types has to do with how the bounds of a node is stored. In Piccolo2D.Java there is a PBounds type which extends Rectangle2D.Double, adding several useful methods. But, the corresponding RectangleF type in .NET cannot be extended. This left us with two choices: create a PBounds class that wraps a RectangleF or use the RectangleF directly. We decided it would be more straightforward to store the bounds as RectangleF objects. Thus, we provide the same methods of Piccolo2D.Java's PBounds as static utility methods in Piccolo2D.NET.
The versions of piccolo2d differ in the primitive types they use too. Since the Java2D API uses doubles, Piccolo2D.Java also stores internal values (e.g. x, y, width, height) as doubles. The GDI+ API on the other hand uses floats. So, Piccolo2D.NET stores these same values as floats.
Another language difference reflected in Piccolo2D is that Java provides anonymous inner
classes while C# has delegates. The Piccolo2D.Java API does not enforce the use of
anonymous inner classes, but, often it is the easiest way to do things. For example,
using anonymous inner classes, you could create a new type of
PBasicInputEventHandler
in place and override just the mousePressed
method. In Piccolo2D.NET, you would have to create a named static class that extends
PBasicInputEventHandler
to do the same thing. This could vastly increase the
amount of code you have to write. So, Piccolo2D.NET provides delegates as a shorthand.
This allows you to instantiate a PBasicInputEventHandler
, and then attach your
event handler method directly to it's MouseDown
delegate. For code examples
see the Piccolo2D Patterns section.
Piccolo2D.NET also takes advantage of several other usability enhancements .NET provides, including a simpler event model, indexers, the foreach loop and type-safe lists. See the API documentation for more details.
Piccolo2D and Jazz
Jazz was our previous ZUI toolkit. The following section outlines the major differences between Piccolo2D and Jazz.
Ease of Use
Our goal with Piccolo2D was to create a ZUI that had a similar feature set to Jazz, but that was easier to use from a programmers standpoint. Almost all the differences between Piccolo2D and Jazz are changes that are meant to make Piccolo2D easier to use.
Complexity
The Jazz framework design is modeled after a 3D scene graph API. It contains many different types of object, each with specific functionality, and these objects are designed to be put together at runtime to produce more complicated objects. This gives the framework flexibility, but requires many different classes and levels of abstraction to support, making it more difficult to use. For example to create a moveable rectangle with Jazz you will need:
- ZRectangle
- This is the ZVisualComponent abstraction
- ZVisualLeaf
- This is a ZNode that is used to place a ZVisualComponent into a scene graph
- ZTransformGroup
- This is a decorator on the ZVisuallLeaf that gives it the ability to be scaled and translated.
Piccolo2D takes a different more traditional 2D approach. There is no separation between ZVisualComponents and ZNodes. So the Piccolo2D version of a rectangle extends directly from PNode and can be place directly into a scene graph without needing to be wrapped in a ZVisualLeaf type object. Piccolo2D has also built many of the most common decorator classes used in Jazz directly into the PNode class. For example every PNode has a affine transform, supports children, and can have its transparency set. So in Piccolo2D to create a movable rectangle all you need is a:
- PPath
- This class represents a graphics path and is used to draw all shapes. It extends from PNode so it has a transform, may have child nodes added to it and all the rest.
Since the Piccolo2D is a complete rewrite, and a smaller code base we also put a lot of time into making the Piccolo2D source code as readable and straightforward as possible. It's our hope that this should make it much easier to add your own new features to Piccolo2D then it was to do with Jazz.
Speed/Memory
The speed differences between Piccolo2D and Jazz for most applications are not large, most time is still spent painting with Java's Graphics2D. With that said Piccolo2D has made significant improvements in the time required to manipulate the scene graph. So if your program is moving around larger numbers of nodes at the same time then Piccolo2D should be faster.
It turns out that for most cases Piccolo2D uses less memory then Jazz. Since instead of needing three different objects to support the normal situation of a movable visible object it only needs one. This together with better bounds management also makes it much faster to create a large number of new objects in Piccolo2D then in Jazz.
The piccolo.jar size is approximately 65k, while the jazz.jar was about 450k. So for applet based applications the Piccolo2D framework will be much faster to download over the web.
Features
Piccolo2D and Jazz support the same basic feature set. They both have structured graphics, and cameras that can look onto that structure using a view transform. So you should be able to build anything in Piccolo2D that was possible in Jazz. At the moment their are some specific features that we have not ported over to Piccolo2D from Jazz yet:
- ZAnchorGroup
- used to specify hyperlinks
- ZClipGroup
- used to specify a clip group around it children nodes
- ZConstraintGroup
- used to constrain a transform based on some calculation. See Piccolo2D Patterns for an easier way to do this in Piccolo2D.
- ZFadeGroup
- all piccolo2d nodes support transparency, something that ZFadeGroup was used for. But ZFadeGroup also supported automatically changing an objects transparency based on scale that it was being viewed at.
- Layout managers
- Piccolo2D doesn't come with any layout managers, but all PNodes have a method layoutChildren() that is easily overridden and will get called for you automatically when the size of any of the children changes.
- ZSelectionGroup
- Used by Jazz's selection management system.
- ZSpatialIndex
- Used for efficient picking and culling objects that won't be painted. Not having this effects speed very little if at all since the vast majority of time is spent painting objects, not culling or picking them.
- ZSwing
- Piccolo2D does not support embedding Swing objects into the PCanvas.
Any needed features should be fairly easy to port to Piccolo2D, please let us know if you need something and we will do our best to include it. We will put most of these features in piccolox (Piccolo2D extras) so that if we do add them the don't complicate Piccolo2D's core classes.
Jazz has some features that will most likely never be supported by Piccolo2D.
- Text file format
- Our recommendation is that applications that need a file format should use define their own and it will make life much easier for everyone. Piccolo2D does support Java serialization for short term persistence.
To learn more about the difference between Jazz and Piccolo2D and why we made this architectural change, you can read Toolkit Design for Interactive Structured Graphics.
Piccolo2D and Other Toolkits
There are numerous graphical toolkits available. This section will explain how Piccolo2D fits in with the myriad of other available toolkits.
Structured Architecture
Piccolo2D is a toolkit for building structured 2D graphics programs. This means piccolo2d maintains a hierarchy of visual nodes that can be grouped, oriented and manipulated in interesting ways. As such, it is very useful for application developers who wish to build custom user interface components and smoothly integrate them with standard application code. Most standard 2D UI toolkits provide little support for building custom components. There are a number of other structured graphics toolkits available. But, many provide a fixed set of shapes that can be added to the canvas, making it difficult to define new classes of objects.
There are also a number of information visualization toolkits available, such as the InfoVis Toolkit, which take a different approach. Rather than maintaining a hierarchy of visual nodes, these toolkits walk along some application-defined data structure, visualizing each item along the way. This approach is simple and it works quite well for visualizing information. Since the data is decoupled from the visualization algorithm, it is also very easy to plug-in new visualizations. But, this sort of toolkit is not as amenable to creating highly customized interaction.
Monlithic Design
Most 3D Graphics toolkits use a polylithic design approach. This means many distinct classes are used to represent both visual and non-visual data. Instances of these classes are then combined at runtime to create more complex objects. This approach is very flexible. And, it promotes abstraction and code reuse. For this reason, some 2D graphics toolkits, such as Jazz and Prefuse, incorporate aspects of polylithic design to varying degrees. But, this approach often results in a proliferation of types, which can be very confusing for a programmer to manage.
Piccolo2D takes a more traditional 2D graphics approach, using compile-time inheritance to extend functionality. Piccolo2D defines a large base class that supports all of the functionality commonly used by different types of visual nodes. New node types are created by extending this base class. We believe this monolithic design approach is much easier for the application developer to use.
Multiple Views, Zooming and Panning
Part of the goal of piccolo2d was to build a toolkit that would enable highly innovative visualization and interaction. To that end, Piccolo2D provides support for multiple cameras, arbitrary node transforms and full-screen zooming and panning. This makes it very easy to build sophisticated data displays, from fisheye visualizations to Zoomable User Interfaces. A number of other toolkits provide support for building innovative visualizations. But, few provide the same level of support for multiple views, zooming and panning.

JSON-LD is a lightweight Linked Data format. It is easy for humans to read and write. It is based on the already successful JSON format and provides a way to help JSON data interoperate at Web-scale. JSON-LD is an ideal data format for programming environments, REST Web services, and unstructured databases such as CouchDB and MongoDB.
The JSON-LD Playground is a web-based JSON-LD viewer and debugger. If you are interested in learning JSON-LD, this tool will be of great help to you. Developers may also use the tool to debug, visualize, and share their JSON-LD markup.
Launch the JSON-LD PlaygroundJSON-LD is available in a number of popular programming environments. Each implementation of JSON-LD listed below is fully conforming to the offical JSON-LD specifications.
The JSON-LD Test Suite is useful for validating JSON-LD Processors.
Conformance of various processors is documented in the implementation report.
JSON-LD is being developed by the W3C JSON-LD Community Group. It is a W3C Recommendation as of 16 January 2014. Participation is open to the public. There is a JSON-LD Github repository. If you need immediate help, we have a #json-ld IRC support channel on freenode.net. There is also a JSON-LD mailing list. All weekly meetings are open to the public, and are minuted, recorded, and archived. Listed below are all of the communication tools that the community uses on a weekly basis.
This website contains a number of curated
video, presentations, tutorials, and documentation about JSON-LD. Assuming you
are familiar with JSON, these training materials will help you quickly
put the power of JSON-LD into your web development efforts.

A data element concept represents the union of an object class and a property. Examples of data element concepts include concepts such as, Person — date of birth, Person — country of birth, and Person — religious affiliation.
A data element concept is solely a conceptual description and does not include values for measurement or collection. Values are described by a value domain, which in combination with the data element concept forms a data element.
A conceptual domain may also be associated with a data element concept, thereby providing meaning to the values associated with the concept. A one-to-many relationship may be formed between a data element concept and suitable conceptual domains.

DUMB is a standalone Java application.
DUMB's main purpose is to fix PDFs exported with SMART notebook software.
Additionally, documents can be converted without fixing them.
Made by Lars Müller aka appgurueu and licensed under the MIT license.
Instructions
Operations
Initiating an operation is done as follows:
- Select the desired type of operation (Fix/Convert)
- Select the source file (Open). Note that the extension needs to match the file type of the document
- Select the destination file (Save). Again, the file extension has to match the desired file type
- Optionally tweak the preferences (Fixed Document Properties) to your desires (only relevant for fixing)
- Initiate the operation (Start)
Fixed Document Properties
Check the boxes to override document properties.
- Pages: How to handle multiple pages - either creating a folder or merging them
- Background: Allows tweaking the background - killing/filling or inside margins
- Width: Total page width in centimetres (cm)
- Margin: Margin of all edges in centimetres (cm)
- Margin-Left/Right/Top/Bottom: Can override the respective margins
Other
About
This page. To be consulted if in need for instructions.
Settings
Allow tweaking global settings.
- Theme: The theme to use
- Office Home: Root directory of your Libre Office / Open Office installation
Logs
Furthermore, you can check detailed reports. Especially useful when reporting errors.


Sometimes you want to repeat a task multiple times. In computer programming, this is called a loop. Common Ansible loops include changing ownership on several files and/or directories with the file module, creating multiple users with the user module, and
repeating a polling step until a certain result is reached. Ansible offers two keywords for creating loops: loop
and with_<lookup>
.
Note
loop
in Ansible 2.5. It is not yet a full replacement for with_<lookup>
, but we recommend it for most use cases.with_<lookup>
- that syntax will still be valid for the foreseeable future.loop
syntax - watch this page and the changelog for updates.loop
and with_*
¶with_<lookup>
keywords rely on Lookup Plugins - even items
is a lookup.loop
keyword is equivalent to with_list
, and is the best choice for simple loops.loop
keyword will not accept a string as input, see Ensuring list input for loop: query vs. lookup.with_*
covered in Migrating from with_X to loop can be updated to use loop
.with_items
to loop
, as with_items
performed implicit single-level flattening. You may need to use flatten(1)
with loop
to match the exact outcome. For example, to get the same output as:with_items:
- 1
- [2,3]
- 4
you would need:
loop: [1, [2,3] ,4] | flatten(1)
with_*
statement that requires using lookup
within a loop should not be converted to use the loop
keyword. For example, instead of doing:loop: "{{ lookup('fileglob', '*.txt', wantlist=True) }}"
it’s cleaner to keep:
with_fileglob: '*.txt'
Repeated tasks can be written as standard loops over a simple list of strings. You can define the list directly in the task:
- name: add several users
user:
name: "{{ item }}"
state: present
groups: "wheel"
loop:
- testuser1
- testuser2
You can define the list in a variables file, or in the ‘vars’ section of your play, then refer to the name of the list in the task:
loop: "{{ somelist }}"
Either of these examples would be the equivalent of:
- name: add user testuser1
user:
name: "testuser1"
state: present
groups: "wheel"
- name: add user testuser2
user:
name: "testuser2"
state: present
groups: "wheel"
You can pass a list directly to a parameter for some plugins. Most of the packaging modules, like yum – Manages packages with the yum package manager and apt – Manages apt-packages, have this capability. When available, passing the list to a parameter is better than looping over the task. For example:
- name: optimal yum
yum:
name: "{{ list_of_packages }}"
state: present
- name: non-optimal yum, slower and may cause issues with interdependencies
yum:
name: "{{ item }}"
state: present
loop: "{{ list_of_packages }}"
Check the module documentation to see if you can pass a list to any particular module’s parameter(s).
If you have a list of hashes, you can reference subkeys in a loop. For example:
- name: add several users
user:
name: "{{ item.name }}"
state: present
groups: "{{ item.groups }}"
loop:
- { name: 'testuser1', groups: 'wheel' }
- { name: 'testuser2', groups: 'root' }
When combining Conditionals with a loop, the when:
statement is processed separately for each item.
See The When Statement for examples.
To loop over a dict, use the dict2items
Dict Filter:
- name: create a tag dictionary of non-empty tags
set_fact:
tags_dict: "{{ (tags_dict|default({}))|combine({item.key: item.value}) }}"
loop: "{{ tags|dict2items }}"
vars:
tags:
Environment: dev
Application: payment
Another: "{{ doesnotexist|default() }}"
when: item.value != ""
Here, we don’t want to set empty tags, so we create a dictionary containing only non-empty tags.
You can register the output of a loop as a variable. For example:
- shell: "echo {{ item }}"
loop:
- "one"
- "two"
register: echo
When you use register
with a loop, the data structure placed in the variable will contain a results
attribute that is a list of all responses from the module. This differs from the data structure returned when using register
without a loop:
{
"changed": true,
"msg": "All items completed",
"results": [
{
"changed": true,
"cmd": "echo \"one\" ",
"delta": "0:00:00.003110",
"end": "2013-12-19 12:00:05.187153",
"invocation": {
"module_args": "echo \"one\"",
"module_name": "shell"
},
"item": "one",
"rc": 0,
"start": "2013-12-19 12:00:05.184043",
"stderr": "",
"stdout": "one"
},
{
"changed": true,
"cmd": "echo \"two\" ",
"delta": "0:00:00.002920",
"end": "2013-12-19 12:00:05.245502",
"invocation": {
"module_args": "echo \"two\"",
"module_name": "shell"
},
"item": "two",
"rc": 0,
"start": "2013-12-19 12:00:05.242582",
"stderr": "",
"stdout": "two"
}
]
}
Subsequent loops over the registered variable to inspect the results may look like:
- name: Fail if return code is not 0
fail:
msg: "The command ({{ item.cmd }}) did not have a 0 return code"
when: item.rc != 0
loop: "{{ echo.results }}"
During iteration, the result of the current item will be placed in the variable:
- shell: echo "{{ item }}"
loop:
- one
- two
register: echo
changed_when: echo.stdout != "one"
You can use Jinja2 expressions to iterate over complex lists. For example, a loop can combine nested lists:
- name: give users access to multiple databases
mysql_user:
name: "{{ item[0] }}"
priv: "{{ item[1] }}.*:ALL"
append_privs: yes
password: "foo"
loop: "{{ ['alice', 'bob'] |product(['clientdb', 'employeedb', 'providerdb'])|list }}"
New in version 1.4.
You can use the until
keyword to retry a task until a certain condition is met. Here’s an example:
- shell: /usr/bin/foo
register: result
until: result.stdout.find("all systems go") != -1
retries: 5
delay: 10
This task runs up to 5 times with a delay of 10 seconds between each attempt. If the result of any attempt has “all systems go” in its stdout, the task succeeds. The default value for “retries” is 3 and “delay” is 5.
To see the results of individual retries, run the play with -vv
.
When you run a task with until
and register the result as a variable, the registered variable will include a key called “attempts”, which records the number of the retries for the task.
Note
You must set the until
parameter if you want a task to retry. If until
is not defined, the value for the retries
parameter is forced to 1.
To loop over your inventory, or just a subset of it, you can use a regular loop
with the ansible_play_batch
or groups
variables:
# show all the hosts in the inventory
- debug:
msg: "{{ item }}"
loop: "{{ groups['all'] }}"
# show all the hosts in the current play
- debug:
msg: "{{ item }}"
loop: "{{ ansible_play_batch }}"
There is also a specific lookup plugin inventory_hostnames
that can be used like this:
# show all the hosts in the inventory
- debug:
msg: "{{ item }}"
loop: "{{ query('inventory_hostnames', 'all') }}"
# show all the hosts matching the pattern, ie all but the group www
- debug:
msg: "{{ item }}"
loop: "{{ query('inventory_hostnames', 'all:!www') }}"
More information on the patterns can be found on Working with Patterns
loop
: query
vs. lookup
¶The loop
keyword requires a list as input, but the lookup
keyword returns a string of comma-separated values by default. Ansible 2.5 introduced a new Jinja2 function named Invoking lookup plugins with query that always returns a list, offering a simpler interface and more predictable output from lookup plugins when using the loop
keyword.
You can force lookup
to return a list to loop
by using wantlist=True
, or you can use query
instead.
These examples do the same thing:
loop: "{{ query('inventory_hostnames', 'all') }}"
loop: "{{ lookup('inventory_hostnames', 'all', wantlist=True) }}"
New in version 2.1.
The loop_control
keyword lets you manage your loops in useful ways.
label
¶New in version 2.2.
When looping over complex data structures, the console output of your task can be enormous. To limit the displayed output, use the label
directive with loop_control
:
- name: create servers
digital_ocean:
name: "{{ item.name }}"
state: present
loop:
- name: server1
disks: 3gb
ram: 15Gb
network:
nic01: 100Gb
nic02: 10Gb
...
loop_control:
label: "{{ item.name }}"
The output of this task will display just the name
field for each item
instead of the entire contents of the multi-line {{ item }}
variable.
New in version 2.2.
To control the time (in seconds) between the execution of each item in a task loop, use the pause
directive with loop_control
:
# main.yml
- name: create servers, pause 3s before creating next
digital_ocean:
name: "{{ item }}"
state: present
loop:
- server1
- server2
loop_control:
pause: 3
index_var
¶New in version 2.5.
To keep track of where you are in a loop, use the index_var
directive with loop_control
. This directive specifies a variable name to contain the current loop index:
- name: count our fruit
debug:
msg: "{{ item }} with index {{ my_idx }}"
loop:
- apple
- banana
- pear
loop_control:
index_var: my_idx
loop_var
¶New in version 2.1.
You can nest two looping tasks using include_tasks
. However, by default Ansible sets the loop variable item
for each loop. This means the inner, nested loop will overwrite the value of item
from the outer loop.
You can specify the name of the variable for each loop using loop_var
with loop_control
:
# main.yml
- include_tasks: inner.yml
loop:
- 1
- 2
- 3
loop_control:
loop_var: outer_item
# inner.yml
- debug:
msg: "outer item={{ outer_item }} inner item={{ item }}"
loop:
- a
- b
- c
Note
If Ansible detects that the current loop is using a variable which has already been defined, it will raise an error to fail the task.
New in version 2.8.
As of Ansible 2.8 you can get extended loop information using the extended
option to loop control. This option will expose the following information.
| Variable | Description |
ansible_loop.allitems |
The list of all items in the loop |
ansible_loop.index |
The current iteration of the loop. (1 indexed) |
ansible_loop.index0 |
The current iteration of the loop. (0 indexed) |
ansible_loop.revindex |
The number of iterations from the end of the loop (1 indexed) |
ansible_loop.revindex0 |
The number of iterations from the end of the loop (0 indexed) |
ansible_loop.first |
True if first iteration |
ansible_loop.last |
True if last iteration |
ansible_loop.length |
The number of items in the loop |
ansible_loop.previtem |
The item from the previous iteration of the loop. Undefined during the first iteration. |
ansible_loop.nextitem |
The item from the following iteration of the loop. Undefined during the last iteration. |
loop_control:
extended: yes
New in version 2.8.
As of Ansible 2.8 you can get the name of the value provided to loop_control.loop_var
using the ansible_loop_var
variable
For role authors, writing roles that allow loops, instead of dictating the required loop_var
value, you can gather the value via:
"{{ lookup('vars', ansible_loop_var) }}"
With the release of Ansible 2.5, the recommended way to perform loops is the use the new loop
keyword instead of with_X
style loops.
In many cases, loop
syntax is better expressed using filters instead of more complex use of query
or lookup
.
The following examples will show how to convert many common with_
style loops to loop
and filters.
with_list
is directly replaced by loop
.
- name: with_list
debug:
msg: "{{ item }}"
with_list:
- one
- two
- name: with_list -> loop
debug:
msg: "{{ item }}"
loop:
- one
- two
with_items
is replaced by loop
and the flatten
filter.
- name: with_items
debug:
msg: "{{ item }}"
with_items: "{{ items }}"
- name: with_items -> loop
debug:
msg: "{{ item }}"
loop: "{{ items|flatten(levels=1) }}"
with_indexed_items
is replaced by loop
, the flatten
filter and loop_control.index_var
.
- name: with_indexed_items
debug:
msg: "{{ item.0 }} - {{ item.1 }}"
with_indexed_items: "{{ items }}"
- name: with_indexed_items -> loop
debug:
msg: "{{ index }} - {{ item }}"
loop: "{{ items|flatten(levels=1) }}"
loop_control:
index_var: index
with_flattened
is replaced by loop
and the flatten
filter.
- name: with_flattened
debug:
msg: "{{ item }}"
with_flattened: "{{ items }}"
- name: with_flattened -> loop
debug:
msg: "{{ item }}"
loop: "{{ items|flatten }}"
with_together
is replaced by loop
and the zip
filter.
- name: with_together
debug:
msg: "{{ item.0 }} - {{ item.1 }}"
with_together:
- "{{ list_one }}"
- "{{ list_two }}"
- name: with_together -> loop
debug:
msg: "{{ item.0 }} - {{ item.1 }}"
loop: "{{ list_one|zip(list_two)|list }}"
with_dict
can be substituted by loop
and either the dictsort
or dict2items
filters.
- name: with_dict
debug:
msg: "{{ item.key }} - {{ item.value }}"
with_dict: "{{ dictionary }}"
- name: with_dict -> loop (option 1)
debug:
msg: "{{ item.key }} - {{ item.value }}"
loop: "{{ dictionary|dict2items }}"
- name: with_dict -> loop (option 2)
debug:
msg: "{{ item.0 }} - {{ item.1 }}"
loop: "{{ dictionary|dictsort }}"
with_sequence
is replaced by loop
and the range
function, and potentially the format
filter.
- name: with_sequence
debug:
msg: "{{ item }}"
with_sequence: start=0 end=4 stride=2 format=testuser%02x
- name: with_sequence -> loop
debug:
msg: "{{ 'testuser%02x' | format(item) }}"
# range is exclusive of the end point
loop: "{{ range(0, 4 + 1, 2)|list }}"
with_subelements
is replaced by loop
and the subelements
filter.
- name: with_subelements
debug:
msg: "{{ item.0.name }} - {{ item.1 }}"
with_subelements:
- "{{ users }}"
- mysql.hosts
- name: with_subelements -> loop
debug:
msg: "{{ item.0.name }} - {{ item.1 }}"
loop: "{{ users|subelements('mysql.hosts') }}"
with_nested
and with_cartesian
are replaced by loop and the product
filter.
- name: with_nested
debug:
msg: "{{ item.0 }} - {{ item.1 }}"
with_nested:
- "{{ list_one }}"
- "{{ list_two }}"
- name: with_nested -> loop
debug:
msg: "{{ item.0 }} - {{ item.1 }}"
loop: "{{ list_one|product(list_two)|list }}"
with_random_choice
is replaced by just use of the random
filter, without need of loop
.
- name: with_random_choice
debug:
msg: "{{ item }}"
with_random_choice: "{{ my_list }}"
- name: with_random_choice -> loop (No loop is needed here)
debug:
msg: "{{ my_list|random }}"
tags: random

| Initial Generic Functions {cubfits} | R Documentation |
Initial generic functions for model fitting/approximation/prediction of cubfits.
init.function(model = .CF.CT$model[1], type.p = .CF.CT$type.p[1], type.Phi = .CF.CT$type.Phi[1], model.Phi = .CF.CT$model.Phi[1], init.Phi = .CF.CT$init.Phi[1], init.fit = .CF.CT$init.fit[1], parallel = .CF.CT$parallel[1], adaptive = .CF.CT$adaptive[1])
model |
main fitted model. |
type.p |
proposal method for hyper-parameters. |
type.Phi |
proposal method for Phi (true expression values). |
model.Phi |
prior of Phi. |
init.Phi |
initial methods for Phi. |
init.fit |
how is coefficient initialed in |
parallel |
parallel functions. |
adaptive |
method for adaptive MCMC. |
This function mainly takes the options, find the according generic
functions, and assign those functions to .cubfitsEnv
.
Those generic functions can be executed accordingly later within functions
for MCMC or multinomial logistic regression such as cubfits()
,
cubappr()
, and cubpred()
.
By default, those options are provided by .CF.CT
which also
leaves rooms for extensions of more complicated models and further
optimizations.
It is supposed to call this function before running any MCMC or
multinomial logistic regression. This function may affect
cubfits()
, cubpred()
, cubappr()
,
estimatePhi()
, and fitMultinom()
.
model
is the main fitting model, currently only roc
is
fully supported.
type.p
is for proposing hyper-parameters in Gibb sampler. Currently,
lognormal_fix
is suggested where mean 1 is fixed for log normal
distribution. Conjugated prior and flat prior exist and are easily available
in this step
type.Phi
is for proposing Phi (expression values) in the random walk
chain updates. Only, RW_Norm
is supported. Usually, the acceptance
ratio can be adapted within 25% and 50% controlled by
.CF.AC
if adaptive = simple
.
model.Phi
is for the distribution of Phi. Typically, log normal
distribution lognormal
is assumed.
init.Phi
is a way to initial Phi. Posterior mean PM
is recommended which avoid boundary values.
init.fit
is a way of initial coefficients to fit mutation and
selection coefficients (log.mu and
Delta.t or omega)
in vglm()
. Option current
means the b
(log(mu) and Delta.t) of current MCMC iteration is the initial values, while
random
means vglm()
provides the initial values.
parallel
is a way of parallel methods to speed up code.
lapply
means lapply()
is used and no parallel;
mclapply
means mclapply()
of parallel is used and
good for shared memory machines;
task.pull
means task.pull()
of pbdMPI is used and
good for heterogeneous machines;
pbdLapply
means pbdLapply()
of pbdMPI is used and
good for homogeneous machines.
Among those, task.pull
is tested thoroughly and is the most reliable
and efficient method.
adaptive
is a way for adaptive MCMC that propose better mixing
distributions for random walks of Phi. The simple
method is
suggested and only the proposal distribution of Phi
(type.Phi = RW_Norm
) is adjusted gradually.
Return an invisible object which is a list contain all
generic functions according to the input options.
All functions are also assigned in the .cubfitsEnv
for later evaluations called by MCMC or multinomial logistic regression.
Note that all options are taken default values from the global control
object .CF.CT
, so one can utilize/alter the object's values
to adjust those affected functions.
Note that phi.Obs
should be scaled to mean 1 before
applying to MCMC.

So you're cruising down a highway, all by yourself, with nothing but beautiful scenic countryside for miles. Your radio is playing your favorite song and the weather is perfect today. Nice. Off in the distance, you see a billboard. A really obnoxious billboard. It's like the hot pink letters on a navy blue background and pea green spots everywhere kind of obnoxious. Who knows what they're advertising, but you certainly don't care. So you ignore it, and do your best to look away from it, (while keeping your eyes on the road!)
That's not so bad, right? Now you can return to your nice peacful country driv- suddenly an obnoxiously loud ad takes over your radio, jarring you out of your zen-like reverie. It's that darn billboard?? How? Is that even legal? What in the world? It's no big deal, just turn off the radio and let the sounds of the road soothe you back into your zen. Ahhh...
Ok, life is good again. Oops. Spoke too soon. Your car suddenly stops working, right in the middle of the highway.  If you do that, your car will work again and you'll be on your way. What in the what? All because you went on a country drive?
Craziness, right? What could you do?  But what if you don't have the mechanical skill to fix your own car, and you don't have the money to pay a mechanic? Or what if you have no idea what a real cop would look or behave like, and you can't tell if he's legit or not? Welcome to the world of malvertising.
Malvertising is the act of using online advertising to sneak malware onto unsuspecting computers. Well, the users are unsuspecting. I guess the computers could be unsuspecting too, because as computers, they can't feel suspicion. Regardless, malware is foisted upon people who never saw it coming! And it's a growing trend, according to CNN.com, who states "the ad tech industry recognizes this is a serious problem."
 I don't click on random ads. Heck, I don't click on any ads! That's the nefarious part; you don't have to click on them. You can be on your favorite trusted website, just cruising their content, and their content alone, and in the background, malicious software is being surreptitiously sent to your computer.
Pfft. Like any respectable site would allow those kind of ads, you say? Hmmm... In early January of this year, anyone who visited sites like The Huffington Post, GameZone, or LA Weekly, among other sites, and were served one of several ads were victims of ransomware, ie software that cuts off access to the mouse and keyboard until the user pays the criminals. This particular piece of ransomware would state they were from your nation's authorities, depending on your location. In the United States, victims saw this:
According to CNN.com, this was a relatively unsophisticated piece of ransomeware, and no files were encrypted. So if you were hit by it, just reboot in safe mode and clean your computer out with an antivirus scan.
It really makes me wish those advertising services would stop allowing this active content in their ads. It's time to go back to just plain image ads! Does anyone really appreciate any of those auto-start ads? Seriously? When they start talking to you out of nowhere?
Anyways, what can the user do to prevent this in the future? Well, with this particular attack, only older browsers were taken advantage of, so it helps to keep your broser current. Also, Internet Explorer is a big no-no, apparently, since it was targeted. And if you were using an old version of Internet Explorer? You deserve what you get! This is why we use better browsers, folks! Your safest bet, of course, would be to block the ads entirely.
 Sunglasses optional, but very cool. That's right, we revisted the highway metaphor. What, you're going to complain to a lady with a jetpack and a bazooka?
I thought not. Keep your browsers current, folks. And friends don't let friends use Internet Explorer.

Talk Overview
We are going to write a Go program. Make a shared object out of that program, and then call that program from python.
Shared Object file?
Shared libraries are libraries that are loaded by programs when they start. In terms of convention, these files are usually kept in a special place and given special names. You can read more about that at http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html
For our purposes, we need to know that we can build shared object files via Go and the the name of these files end in ".so".
Lets build a hello world shared object file!
go build -o output_file.so -buildmode=c-shared source_file.go
Ctypes Module
Ctypes is a foreign function library for Python. It provides C compatible data types, and allows calling functions in DLLs or shared libraries. It can be used to wrap these libraries in pure Python.
Lets call our shared object file from Python!
What can we pass into Go?
What can we return from Go?
Slices? Maps? I am not even going to try.
What do we know?
Contrived Examples
The ability to use Go to Create shared objects files and dynamically call them in Python is cool, but it is not easy.
If you do not need Go and Python to talk directly to one another, then you are GOLDEN!
You can then store all the data that needs to be passed from one language to the other in files that can then be read and written to by both Go and Python.


Since around 2008, I've been playing around in photoshop and
have become pretty efficient with the Adobe Suite. In 2011 I bought my first real
camera with a few lenses and have been doing a lot of landscape photography and
occasionally portrait and family pictures. Since around 2016 I've been teaching
myself web development and have become proficient with php, html and css. More
recently I've been trying to learn React and dive deeper into javascript.
Skillset
Web Development
I've been building websites here and there since 2016,
but have recently been driven to try and dive back into the feild again. I
love both development and design, but what I love most is the finished
product and knowing anyone, anywhere can see what I've had the pleasure of
creating.
Graphic Design
Ever since I discovered Photoshop, I've loved the idea that I
can create anything I want with a little time and effort. I've most recently
invested in a vinyl cutter and printer and have been designing my own stickers,
shirts, and anything else that I find interesting, such as an artsy spin on bottle
openers I make out of reclaimed wood.
Photography
I will always love the fact that I bought a camera all those
years ago and for the time I spent in a darkroom in my younger years. Photography
has been a godsend in both development and design because I will always have the
ability to take a photo of mine and change it into a different work of art. Whether
it be a background image for a webpage, or snapping pictures of snowboarders and
having the ability to make that photo into a sticker. I will always try and use my
own photos before I'll start browsing around for stock images.
SEO and Marketing
As soon as I started learning web development, I started
looking into search engine optimization and marketing. Marketing came first when I
was working for a small garage door company and I have learned a lot from trying to
boost business so that I could stay busy with work. That's actually what got me
started with web development because his site was outdated and I knew with my drive
of always wanting to learn something new, that I could make something better and
help myself in the long run. This is the reason I've learned things such as schema
markup and my love for graphic design has led me to create various marketing
materials.

Jordanian customs in celebrations
The customs of Jordanians in celebrations are the most beautiful part of our culture because Jordanians love to dance, sing and be happy, and there are many customs and traditions, some of which you will see here. There are various occasions such as national , religious , social and others occasions that Jordanians celebrate in it every day and every year . How do Jordanians express their happiness in these various occasions ? What are their customs and traditions in the celebration ?
Dabke
It is a Jordanian folk dance.Dancers line up in a row or in a circle.They are male or female, and the dances are performed either mixed or separated by the sexes.The dance is led by the first dancer and he generally determines the direction of the dance and usually performs additional movements that demonstrate his skill. The dabkeh consists of leg movements and is characterized by loud striking on the ground, accompanied by folk music playing.
The Jordanian Samer dance (Aldihya)
is a Bedouin dance practiced in Jordan on weddings and other celebrations, and it combines the art of poetry and dance. its performed collectively The men line up in one or two opposite rows and sway left and right. The poet in the middle of one of the two rows sings his poem and repeats the two rows alternately and the dance is sometimes slow with foot movements and quick successive movements.
Al-Farda
is an important thing in Jordanian events such as weddings and graduations, and it is a group of cars that drive behind each other and they show their happiness by singing and honking the cars along the road. In weddings, for example, the bride and groom's car is decorated with roses, and the cars of the groom's relatives are with him, and singing and (buzzing) begin in the car as an expression of joy until they reach their home or the wedding hall.
Food feast
Also in the celebrations, after the Jordanians express their happiness by dancing and singing, a lunch or dinner feast is held to thank the people who came to the celebration, which consists of many dishes of mansaf, the most popular dish in the governorates.and if this indicates anything, it indicates the hospitality of the Jordanians .

History
History of Indian Football Fans and Blue Pilgrims.
Until the 2000s, India football fans were mostly scattered, being widely based in West Bengal, North-East India, Goa, and Kerala Other than matches at the Asian Games, Nehru Cup, or SAFF Championship, fans showed up in small numbers when the team played, and fans of different clubs used to support the team in their respective local venues. In 2017, the Blue Pilgrims were established as the first organised fan club for the national team.
Blue Pilgrims
The Blue Pilgrims were formed with a motive to support the national team and the U-17 team during the historic 2017 U17 World Cup, India's first-ever FIFA competition participation. Begun with some 300 fans, the group grew to encompass thousands, with fans from different regions and with different allegiances coming together to support the Blue Tigers. They call themselves the devotees of the Blue Tigers, and their objective is to support India national football teams of all genders and ages, wherever they play. For their dedication, they have been called the "12th man" of the team.
Slogans and Banners
The Blue Pilgrims's most common chants are: "Oh India!", a) "In Unity we stand", b) "Oh India we stand for you!", c) and "Vande Mataram". Their sports anthems are "Oh when the blues go marching in, I wanna be in that number!" (sung to the tune of "When the Saints Go Marching In"), and "Hum honge kaamyab" (We Shall Overcome). Since their formation, the Blue Pilgrims celebrate after every match with the Viking clap together with national team members.

Usually, bonds are considered less risky than stocks. A portfolio with a heavier allocation towards bonds is going to be considered more risk adverse. Less risk usually correlates with less yield (lower performance).
The conventional recommendation for asset allocation is to subtract your age from 100 to determine the percentage your portfolio should be allocated towards stocks. The thinking is that we can tolerate less risk as we get older, because we have less of a time horizon to recover from market crashes, and we are closer to needing money for retirement.
The new recommendation is to subtract your age from 120 to determine the percentage your portfolio should be allocated towards stocks. This is due to a longer expected life span.
A fund is typically considered less risk than an individual bond/stock, because as a basket of bonds/stocks, it offers more diversification.
These funds are ranked from low risk to high risk:
- BSV - short-term bond fund
Short-term bonds lock up funds for a shorter period of time (less than 5 years), so there is less risk for price fluctuations.
- BIV - intermediate-term bond fund
Intermediate-term bonds lock up funds for 5-10 years.
- BND- total bond fund
Total bond funds have both intermediate-term bonds and long-term bonds (more than 10 years).
- VV - large-cap stock fund
Large-cap funds are composed of larger companies with market capitalization over $10B that offer more stability.
- VEU - foreign large-cap stock fund
Foreign large-cap funds have large, stable foreign companies, but sometimes carry more risk because it's international. There are no US companies.
- VB - small-cap stock fund
Small-cap stocks are companies that are more volatile with a market capitlization between $300M and $2B, but there is usually significantly more growth potential.
- VWO - emerging markets stock fund
These funds invest in companies located in emerging markets like China, Brazil, and South America. There is high potential for growth, but also high risk with less stable markets.


The author of the blog post makes a very decisive claim. The claim that the author is making is that: If a parent is an abortion supporter and a child is diagnosed with an disability before birth, then the parent will abort the child. If the child is diagnosed with a disability before birth and the parent aborts the child, then the parents do not support people with disabilities. Therefore, abortion supporters do not support people with disabilities. We can assign each statement in the following way:
\(p\text{:}\) A parent is an abortion supporter.
\(q\text{:}\) A child is diagnosed with a disability before birth.
\(r\text{:}\) The parent will abort the child.
\(s\text{:}\) Aboftion supporters do not support people with disabilities.
This can be represented by the following: \([((p\wedge q)\implies r)\wedge ((q\wedge r)\implies s)]\implies(p\implies s)\text{.}\) Use the truth table generator to determine if this is a valid argument.

Tuscany DAS Tools
Building DAS Tools
DBToXSDGenerator provides utility methods for use when DB Schema is available and SDO Model xsds are not. This
utility will help build SDO Model xsds based on DB Schema. These xsds can be supplied to Data Access Service
like (RDB-DAS) to have SDO <-> DB data exchange.
- getModelFileFromDB(String dbInfoFile) - connect to database and convert DB Schema to XSD Model XSDs
- getModelFileFromSchemaFile(String schemaFileName, String SDOModelFileName) - no DB Connection needed, but need Apache Torque output of DB schema file
- getSchemaFileFromDB(String dbInfoFile) - connect to database and use Apache Torque to get DB Schema xml file
- getModelFileFromDB(ModelXSDGenOption mo) - connect to database and convert DB Schema to XSD Model XSDs
- getModelFileFromSchemaFile(ModelXSDGenOption mo) - no DB Connection needed, but need Apache Torque output of DB schema file
- ModelXSDGenOption holds - schemaFile, modelFile, driverClass, databaseURL, schemaName, userName, password
To build the Tuscany DAS DBToXSDGenerator tool, perform the following steps
- Ensure that the environment variable JAVA_HOME is set to point to an installation of Java 1.4 JDK
- --->To run as a maven plugin, run the command "mvn"
- --->To run as a standalone tool, call the above listed methods from DBToXSDGenerator
Assumption Database exists and contains required tables, constraints. Required Driver jar is in classpath

To see if an app is running in AppScale, we just see if the app is already uploaded, returning the opposite of that to indicate if it needs to be uploaded.
# File ../Neptune/lib/task_engines/task_engine_appscale.rb, line 42 def app_needs_uploading?(job_data) NeptuneManager.log("Seeing if app needs to be uploaded, with " + "job data #{job_data.inspect}") uac = UserAppClient.new(job_data['@uaserver_ip'], job_data['@secret']) needs_uploading = !uac.is_app_uploaded?(job_data['@appid']) NeptuneManager.log("Does app #{job_data['@appid']} need uploading?

To get the URL that an app can be reached with in AppScale, just find out where the login node is. It provides a app-specific route that will automatically route users to the app.

Quick! Something particularly exciting has happened!  At a particularly exciting moment, the reporter has got to turn to the camera and say something to the effect of "Are We Getting This" The answer is usually yes, but it's anyone's guess as to whether the camera will survive the episode.
There is always the possibility that the "reporter" type person will see the entire event happen and conclude before they can ask this important question. In these cases the question becomes more like: "Did we/you get that?" "Did somebody record that?" They may even beg: "Please tell me somebody got that on video." The results are generally similar.
Examples:
- Possible variation: in Naruto the Movie: Ninja Clash in the Land of Snow, the movie director keeps yelling "Keep filming, keep filming!" every time someone attacks the princess/actress Naruto's group is protecting.
- A variation (sans the stock phrase) appears in Penguin Revolution when Ryo and his rival Narazaki get into a fight on the set of the sentai show they're filming. Since the episode being filmed calls for their characters to fight, the director of the episode immediately demands that the cameras start rolling.
- Used in an episode of Pokémon. The English dub had the reporter comment that Team Rocket was making a dramatic exit through the roof - then she turned to the camera and said gleefully "Just like our ratings will!"
- This is what happens in Digimon Adventure 02 when some rogue Digimon crash a Christmas Eve concert.
- Dragon Ball:
- In the very first tournament arc in Dragon Ball, the announcer actually asks Krillin and Jackie Chun to redo one part of their fight at a slower pace because they were going so fast nobody could see it. Chun consents, as it's for television, but asserts that this he won't do it again, so they'd better pay attention.
- Happens in Dragon Ball Z during Trunks and Goten's match at the tournament. Unfortunately, the kids are moving so quickly that the cameras can't keep up.
- An issue of Runaways uses this, only with a little bit more swearing.
- Used to tragic effect during the Onslaught Saga, with longtime X-Men character Trish Tilby's video report appearing to show the X-Men betraying and murdering the Fantastic Four and Avengers.
- The Transformers, Vol. 2 issue #54, when Cybertronian reporter Circuit asks his cameraman Longtooth if he's catching footage of Optimus Prime summoning Metrotitan from the Earth's ground.
Circuit: Longtooth, old buddy...tell me you got that on camera.
- The Grim Adventures of Billy & Mandy: "No Pain, No Game" (Cartoon Network Block Party #53) has Billy auditioning for an extreme Japanese game show. He has Mandy record his actions with a video camera, none of which gets on tape because Mandy (perhaps deliberately) left the lens cap on.
- Die Hard: A reporter asks his cameraman this twice - played straight after a massive explosion inside Nakatomi Plaza, and then sarcastically after being punched in the face by Holly Gennero.
- Inverted in Die Hard 2 when the cameraman, seeing Holly and John finally getting together and starting to kiss, remarks that he is getting it to the news reporter. She then covers the camera, deliberately ruining the shot.
- In Pearl Harbor, while the Japanese are attacking the titular location, one of the characters is filming the planes coming in with a camera yelling "This is great footage!" Too bad, he gets shot for his trouble, on camera.
- [REC] 2 has a priest following a SWAT team through an apartment building, constantly ordering a camerman to film various things they encounter.
- In The Rocketeer when the eponymous hero takes to the air with his Jet Pack to rescue a friend at an air show. The cameraman doesn't know what it is, but he sure is getting it.
- In Scott Westerfeld's book Extras, the main character, Aya, is constantly asking her hovercam, Moggle, "Are you getting this?"
- Done on Babylon 5, when an Earth reporter gets rare footage of Ambassador Kosh... leaving his quarters, seeing the reporters, and immediately going back inside.
- Asked repeatedly by D'Anna Biers, the reporter in the Battlestar Galactica (2003) episode "Final Cut".
- Said by the remote operators who find the faked wreckage of Oceanic 815 in the Lost episode "Confirmed Dead."
- Saturday Night Live:
- A Running Gag on the recurring "Boston Teens" skit involved someone making an Accidental Inneuendo comment, at which point Sully (one of the teens in question) would turn to the camera and says "Tommy (the unseen teen holding the recorder), please tell me you got that!"
- In one of the Celebrity Jeopardy! sketches, Will Ferrell as Alex Trebek has this response to a Final Jeopardy! response that could actually be interpreted as correct. ("Where are you?" "Indoors.")
- In an episode of Sanctuary, the reporter witnesses a number of nasty things, is duly horrified and then, as soon as she can speak again, asks "did we get that?".
- The Suite Life on Deck: When Baily's possessed by a an ancient princess, she attacks Zack (as he's being interviewed by a local reporter for discovering an ancient artifact.) Her response?
Reporter: Get this! This will be better than my story on the coconut that looked like Estabon Francesco!
- The Whiteboard: Daryl managed to take down Doc using one of Doc's ''special'' paint grenades. Red asks if anybody got it on video. Bandit had 2 GoPros and an iPhone.
- Draconia Chronicles: In a Valentines Day extra (filler) page, the Animated Actors switch gears and do something "Valentines-ey."
- Schlock Mercenary has this show up ("Are you getting all this?" "Are you kidding?"); When you have a crisis where a character earns the name "Longshoreman Of The Apocalypse", you had better hope someone is filming.
A lone figure stands unbuffeted at the edge of the hole. In the shadow of the mighty ship, and at the heart of the Maelstrom.He is The Longshoreman Of The Apocalypse, and at his command this apocalypse is drawn to a crushing end....He is going to make the news.
- Used during part one of the DuckTales (1987) Five-Episode Pilot "Treasure of the Golden Suns", during Scrooge and his nephews' confrontation with the Beagle Boys at the candy factory.
- Frisky Dingo:
Grace Ryan: (gasps) Are you getting this?Cameraman: Am... am I getting footage of me, the cameraman? Absolutely not.
- Played straight in the Buzz Lightyear of Star Command movie. After Buzz finishes his Patrick Stewart Speech, Zurg makes sure it has been captured on camera so that he can laugh at it later.
- Inverted in the Jackie Chan Adventures episode "Snake Hunt", when TV archaeologist Wesley Rank encounters a gigantic snake but is more concerned with getting out alive and in possession of the snake talisman it's guarding. Rank's camera operator remains calm and shines the camera's spotlight into the snake's eyes.
Rank: Crikey, I didn't tell you to film that!
Cameraman: Hello, I'm blinding it! Snakes don't have eyelids! - Dastardly and Muttley in Their Flying Machines: In "Lens A Hand," Dick Dastardly has Muttley take photos of the Squadron in action to prove to the General that they're not just collecting flight pay. Muttley gets everything—mistakes and all.
