Action : Get list of ports
This action retrieves the names of serial ports which are connected devices (printers, mobile phones ...). For more information, see the What is a serial port? document.
Parameters
| Parameters | Descriptions |
|---|---|
| Variable receiving the list of serial ports connected | Must be equal to the array variable receiving the names of serial ports which devices are connected. |
Returned value
The return value is determined by devices connected to the computer. It will be saved in the variable defined in the parameter "Variable receiving the list of serial ports connected". This value is a list of text values (System.String).
Code Visual Basic.Net generated by SoftwareZator
If the variable receiving the result is "Resul", the generated code will be as follows :
Result = New System.Collections.Generic.List(Of Object)(System.Linq.Enumerable.Cast(Of Object)(System.Linq.Enumerable.AsEnumerable(System.IO.Ports.SerialPort.GetPortNames())))
Runtime errors
Sometimes a computer program encounters a problem during execution. Often, an error message is displayed. The table below allows you to determine why the error you encounter appears and how to correct :

Declarative
Holy guacamole! Best check yo self, you're not looking too good.
It's going to be a wonderful day!
It's not what you know!


There is none. They are mostly point-free!
.
or
as in point-free programming,
a point is a function argument
public static final void myFunction(String x) {...}
↑
== tacit programming
a programming paradigm in which function definitions do not identify the arguments (or "points") on which they operate. Instead the definitions merely compose other functions, among which are combinators that manipulate the arguments.
unix pipes
echo "hello old" | tr "h" "H" | sed s/old/world/
which in Java could be:
Function<String,String> f1 = str -> str.replace('h', 'H');
Function<String,String> f2 = str -> str.replace("old", "world");
f1.andThen(f2).apply("hello old");
Haskell
keepEven list = filter (\x -> x `mod` 2 == 0) list
keepEvenPointFree = filter (\x -> x `mod` 2 == 0)
keepEvenEvenMorePointFree = filter ((== 0) . (`mod` 2))
If you know Haskell and partial application,
the last one is perfectly readable.
== eta-reduction and eta-abstraction
Point-free style can be obtained via eta-reduction:
\x -> abs x ==> abs
The opposite of eta-abstraction:
abs ==> \x -> abs x
Conversion to (at least some) point-free form can be automated: http://pointfree.io
keepHalf list = take (length list `div` 2) list
> nix-shell -p haskellPackages.pointfree --run \
"pointfree -v '\list -> take (length list \`div\` 2) list'"
keepHalfPointFree = ap (take . flip (div . length) 2) id
🤔 Wait a second, that doesn’t look simple or easy!
Point-free style can (clearly) lead to Obfuscation when used unwisely. ... Perhaps these are why pointfree style is sometimes (often?) referred to as pointless style.
https://trends.google.com/trends/explore?date=all&q=point-free
https://trends.google.com/trends/explore?date=all&q=tacit%20programming
Uh, didn't look too good...
https://trends.google.com/trends/explore?date=all&q=combinator
Let’s use this one!
A function or definition with no free variables == A pure lambda-expression that refers only to its arguments
https://wiki.haskell.org/Combinator
A combinator is a higher-order function that uses only function application and earlier defined combinators to define a result from its arguments.
https://en.wikipedia.org/wiki/Combinatory_logic
\a -> a
\a -> \b -> a
\f -> \a -> \b -> f b a
It is perhaps surprising that lambda-calculus can represent any conceivable computation using only the simple notions of function abstraction and application based on simple textual substitution of terms for variables. But even more remarkable is that abstraction is not even required. Combinatory logic is a model of computation equivalent to lambda calculus, but without abstraction.
no abstraction == no creation of lambdas
== no function arguments
But the example combinators on the previous slide were lambdas themselves!?!
Yes, but we assume that there exists a primitive set of combinators, from which more can be built without lambda abstraction.
Lambda calculus is sometimes also called λK-calculus, meaning that in combinator logic there’s a K combinator involved.
K x y = x
K is cancellative, it doesn’t use one of it’s arguments.
In λI-calculus, there’s no K
(that is, all arguments must be used)
Single-letter-names are a bit mathy.

keepHalf list = take (length list `div` 2) list
keepHalfPointFree = ap (take . flip (div . length) 2) id
phoenix == pass a single value through two different functions,
and pass the results to a two-parameter function
phoenix x y z w = x (y w) (z w)
keepHalfCombi = phoenix take ((`div` 2) . length) id
starling == pass a single value straight and also through a function, to a two-parameter function
starling = x y z = x z (y z)
keepHalfCombi2 = starling (flip take) ((`div` 2) . length)
cardinal' == pass first argument straight, and second argument through a function,
to a two-parameter function
warbler == elementary duplicator
cardinal' x y z w = x (y w) z
warbler x y = x y y
keepHalfCombi3 = warbler $ cardinal' take ((`div` 2) . length)
There might be a day, when these are taught in the universities and we all know all these combinators by heart!
...meanwhile, is there something easier?
Starling == Applicative's (<*>) on functions
Like ordinary application of take with two arguments:
keepHalf list = take (length list `div` 2) list
but instead we use kind of lifted function application,
syntactically with operators <$> and <*>:
keepHalfApplicative = take <$> ((`div` 2) . length) <*> id
This is actually readable!
By abstracting over function application in our language, we might not even need the operators...
Can be visualised as data flow
nix-shell --pure -p graphviz --run 'echo "digraph g{\
rankdir=\"LR\";\
\"input-list\" -> \"((\`div\` 2) . length)\";\
\"((\`div\` 2) . length)\" -> \"take :: Int -> [a] -> [a]\";\
\"input-list\" -> \"take :: Int -> [a] -> [a]\";\
\"take :: Int -> [a] -> [a]\" -> \"result-list\"\
}" | dot -Tsvg > graph.svg'
Imagine your editor/IDE to automatically visualize all Applicative-function usages with this kind of (even interactive) graphics!
Each previous example had something awkward
missingBird :: (b -> a -> c) -> (a -> b) -> a -> c
missingBird x y z = x (y z) z
keepHalfCombi4 = missingBird take ((`div` 2) . length)
I couldn't find references to this kind of combinator...?
-- from Haskell base:
sortBy :: (a -> a -> Ordering) -> [a] -> [a]
someListOfTuples = [(1,'a'), (2,'b')]
sortedByNumberVerbose = sortBy (\t1 t2 -> compare (fst t1) (fst t2)) someListOfTuples
Do we happen to have a combinator for:
Pass both parameters through same function,
and pass the results to a two-parameter function?
psi x y z w = x (y z) (y w)
sortedByNumberCombinator = sortBy (psi compare fst) someListOfTuples
This need was recognised ages ago
There’s already a psi bird with a different name in Haskell base: on
-- http://hackage.haskell.org/package/base/docs/Data-Function.html#v:on
sortedByNumberOn = sortBy (compare `on` fst) someListOfTuples
nix-shell --pure -p graphviz --run 'echo "digraph g{\
rankdir=LR;\
\"compare\" -> \"on :: (b -> b -> Ordering) -> (a -> b) -> a -> a -> Ordering\";\
\"fst\" -> \"on :: (b -> b -> Ordering) -> (a -> b) -> a -> a -> Ordering\";\
\"on :: (b -> b -> Ordering) -> (a -> b) -> a -> a -> Ordering\" -> \"sortBy :: (a -> a -> Ordering) -> [a] -> [a]\";\
\"input-list\" -> \"sortBy :: (a -> a -> Ordering) -> [a] -> [a]\";\
\"sortBy :: (a -> a -> Ordering) -> [a] -> [a]\" -> \"result-list\"\
}" | dot -Tsvg > graph2.svg'
"Point-Free or Die: Tacit Programming in Haskell and Beyond" by Amar Shah
aggregation == first map over the function f,
then sum the resulting numbers
aggregate f list = sum (map f list)
in point-free style?
aggregate f = sum . map f
aggregate = (sum .) . map
Would we happen to have a combinator for:
pass two parameters to a two-parameter function, and then pass the result to a one-parameter function?
blackbird x y z w = x (y z w)
blackbird == composition of composition and composition
(.) . (.)
Yeah right, but the visualisation is clear
A function with the same type signature as blackbird happens to be defined in multiple Hackage packages with different name.
Could it be useful to have it defined in base with a suitable name, like that suggested by Amar Shah:
f ... g = (f .) . g
Forget that cutting edge JavaScript framework!
Learn you a fundamental tool for great good!
Thank you.

Breaking: Thugs Fight Over Distribution Of INEC Materials In Bayelsa
by George OgboluPolitical thugs have clashed over the movement of voting materials to polling units in Otueke, Ngbia LGA of Bayelsa State.
Naija News reports that the incident happened at INEC’s Registration Area Centre (RAC) inside Community Secondary School, Otueke at 10.45 a.m.
Thugs who were armed sent journalists and election observers scampering for safety.
The angry youths had disagreed over the destination of a set of voting materials.
An INEC official, who spoke with The Punch attributed the late distribution of voting materials to the stance of some of the youths in the community.
“Blame the community youths for the late distribution of voting materials. The materials came in around 11.30 a.m., but the community youths insisted we should not move them,” the INEC official stated.

The other universe is in trouble! There must be some matter from this universe that is still causing disturbances over there. Professor Hemlock has dispatched researchers around ⊥IW to pinpoint the source, and they report the following measurements:
| Round | Measurement (in meters) |

| Athletics | The number of eggs to deliver times the number of goose tasks, plus the numbers of violet coins in space, legendary fish, and football routes. |
| Students | The product of the atomic numbers of Joshua and Anderson. |

In an average month, San Francisco's SOMA neighborhood is host to more than 30 workshops, classes, and study groups that are:
And thosre are just the ones about the principal languages of the Rails stack: Ruby, HTML, CSS, and JavaScript.
Yes, 30 events per month that meet all of those criteria.
So many opportunities to see, do, learn, teach, lead, mentor.
This weekend I had the pleasure of volunteering at yet another of these local events. RailsGirls held its second workshop in San Francisco; another organization easing into this vibrant mix. Welcome, RailsGirls grads! Here's a couple slides introducing you to the abundance of local answers to "What's next?" I hope we'll get to see you again, soon, at several of 'em.
UPDATE: Fixed the hashtag. Added 2 more resources.

Below are two bordered DIV elements. They have exactly the same CSS styles, with one exception: The top one has box-sizing: border-box
, and the bottom one does not.
Ravana carries Sita away to Lanka, where Sita is kept under the heavy guard of rakshasis. Ravana demands Sita marry him, but Sita, eternally devoted to Rama, refuses. Rama and Lakshmana learn about Sita's abduction, and immediately set out to save her. During their search, they meet the demon Kabandha and the ascetic Shabari, who direct them towards Sugriva, the monkey king, and Hanuman.
Having received Hanuman's report on Sita, held prisoner in Lanka, Rama and Lakshmana proceed with their allies towards the shore of the southern sea. There they are joined by Ravana's renegade brother Vibhishana. The monkeys construct a giant floating bridge across the ocean, and the princes and their army cross over to Lanka. A lengthy battle ensues, in which Rama eventually kills Ravana.
The top bordered DIV element is constrained to the width specified for all DIVs on this page — including the DIV that encloses this paragraph. The bottom bordered DIV is wider because the border width and the padding width have been added to the DIV's specified width (which may be given in rems, ems, pixels, or percent).

Qpid Proton 0.12.0 Release Notes
Proton is a high-performance, lightweight messaging library. More
about Qpid Proton.
For more information about this release, including download links and
documentation, see the release overview.
Note: This release contains a new C++ binding of the Proton API.
The documented API is substantially settled, but there are some areas
that will change in the next release and should be considered unstable
API:
- The
proton::connection_engine
and the proton::io
interfaces
- The
find_sessions
and find_links
methods on connection
and
session
Note: Qpid C++ 0.34 builds will fail against this version of Proton
unless you set -DCMAKE_CXX_FLAGS=-Wno-error=switch
. A new release
of Qpid C++ will resolve this problem.

Defining Your Own Custom Objects
Getting Started
To define your own custom objects to use in your RoML files, you have to know how to create ROBLOX objects with Lua. You will need to write a couple of functions that the library can use in order to create and update your custom object.
Where to Put Your Custom Object Scripts
After installing the RoML library, there will be a folder that you can use: game.ServerScriptService.com.blacksheepherd.customobject.user
.
Any ModuleScripts you put in this folder will be used as a custom object.
The name of the ModuleScript becomes the name of your custom object.
What to Put In The Custom Object ModuleScript
The ModuleScript needs to return a table with a couple of functions in it. Write these functions based on the guidelines described below. Your custom object is a sub-class of the CustomObject class, so most of the functions get passed a reference to self.
Required Functions
These functions are REQUIRED in order for the custom object to work properly.
Create
The first required function is the Create function. The function will be passed a single argument and that is the CustomObject instance. You should return a ROBLOX Instance object in this function.
The purpose of this function is to create the ROBLOX objects that you want to create from your custom object. It is called every time your custom object is created.
As an example, here is the Create function for the library's custom SpriteSheet object:
Create = function(self) frame = Instance.new("Frame") frame.ClipsDescendants = true frame.Name = "SpriteSheetFrame" spriteSheet = Instance.new("ImageLabel", frame) spriteSheet.Name = "SpriteSheet" return frame end
Note that you don't need to set the parent of the ROBLOX object you return. The RoML library does that automatically for you.
UpdateProperty
The final required function is the UpdateProperty function. Whenever a property is passed to your object, it is passed to this function. Three arguments will be passed to this function: the CustomObject (same as before), the name of the property, and the value of the property. Nothing needs to be returned.
Any properties you don't want to accept can just be ignored. Nothing will happen if the library tries to set these properties.
Here is the UpdateProperty function from the SpriteSheet object:
UpdateProperty = function(self, name, value) frame = self:GetRobloxObject() if name == "Name" then frame.Name = value elseif name == "Position" then frame.Position = value elseif name == "SpriteSheet" then frame:FindFirstChild("SpriteSheet").Image = value elseif name == "Size" then frame.Size = UDim2.new(0, value.x, 0, value.y) elseif name == "Index" rows = math.floor(frame.Size.Y.Offset / 256) cols = math.floor(frame.Size.X.Offset / 256) x = value % self.Custom.cols y = math.floor(value / self.Custom.rows) frame:FindFirstChild("SpriteSheet").Position = UDim2.new(0, -x * frame.Size.X.Offset, 0, -y * frame.Size.Y.Offset) end end
You can call the RomlObject.GetRobloxObject method on self, like in the example, to get the object you created in your Create function.
Optional Functions
Any other functions within the table are optional. You may choose to define these functions only if your custom object needs them.
PropertyUpdateOrder
This function is used to tell the library the order in which to update properties. Again, this function is passed in a reference to the CustomObject. The function returns an array with the name of each property, in the order they should be updated. If you do define this function, make sure to include all property names in the array, otherwise not all properties will get updated.
Here is the example from the SpriteSheet:
PropertyUpdateOrder = function(self) return {"Name", "Position", "SpriteSheet", "Size", "Index"} end
Most of the order doesn't matter. For the Index property, however, it is important that it gets updated after the Size gets updated since the calculations rely on the Size property.
AllowsChildren
This function tells the library whether or not the object should allow children objects. Again, this function is passed in a reference to the CustomObject. It should return a boolean. If you don't define this function, it will allow children by default.
SpriteSheet example:
AllowsChildren = function(self) return false end
If the object doesn't allow children, an error will be thrown if one is attempted to be added.
FilterProperty
The final optional function allows you to define shorthand property values, just like the RoML library allows. This function is called while the RoML or RoSS file is being compiled, but not a run time. In the future, property filters may be added during run time. The arguments passed to the function are the name of the property, the value of the property (as a string), the LiteralString class, and the CompilerPropertyFilter module. The function must return a LiteralString, which is why the class is passed to the function. You may also use the Filter functions in the CompilerPropertyFilter module (which return a LiteralString) to help.
If you don't want to filter a property, just return a LiteralString of the value. The library handles the rest. Once again, here is the FilterProperty function from the SpriteSheet object:
FilterProperty = function(name, value, LiteralString, CompilerPropertyFilter) if name == "Position" then CompilerPropertyFilter.UDim2Filter(value) elseif name == "Size" then CompilerPropertyFilter.Vector2Filter(value) else LiteralString(value) end end
Full Custom Object Template
For your convenience, the contents of the custom object ModuleScript (without function bodies) is including below:
return { Create = function(self) end, CreateProperties = function(self) end, PropertyUpdateOrder = function(self) end, UpdateProperty = function(self, name, value) end, FilterProperty = function(name, value, LiteralString, CompilerPropertyFilter) end, AllowsChildren = function(self) end }

| 5.6 DRAFT ADDITION TO DOCUMENTATION |
|---|
| This feature has additional or changed functionality in Unity 5.6. The link below is first draft document of that addition or change. As such, the information in this document may be subject to change before final release. See first draft Light Modes documentation. |
This page details the deferred shading rendering path. See Wikipedia: deferred shading for an introductory technical overview.
When using deferred shading, there is no limit on the number of lights that can affect a GameObject. All lights are evaluated per-pixel, which means that they all interact correctly with normal maps, etc. Additionally, all lights can have cookies and shadows.
Deferred shading has the advantage that the processing overhead of lighting is proportional to the number of pixels the light shines on. This is determined by the size of the light volume in the Scene regardless of how many GameObjects it illuminates. Therefore, performance can be improved by keeping lights small. Deferred shading also has highly consistent and predictable behaviour. The effect of each light is computed per-pixel, so there are no lighting computations that break down on large triangles.
On the downside, deferred shading has no real support for anti-aliasing and can’t handle semi-transparent GameObjects (these are rendered using forward rendering). There is also no support for the Mesh Renderer’s Receive Shadows flag and culling masks are only supported in a limited way. You can only use up to four culling masks. That is, your culling layer mask must at least contain all layers minus four arbitrary layers, so 28 of the 32 layers must be set. Otherwise you get graphical artefacts.
It requires a graphics card with Multiple Render Targets (MRT), Shader Model 3.0 (or later) and support for Depth render textures. Most PC graphics cards made after 2006 support deferred shading, starting with GeForce 8xxx, Radeon X2400, Intel G45.
On mobile, deferred shading is not supported, mostly due to MRT formats used (some GPUs which do support multiple render targets, still only support very limited bit counts).
Note: Deferred rendering is not supported when using Orthographic projection. If the Camera’s projection mode is set to Orthographic, the Camera falls back to Forward rendering.
The rendering overhead of realtime lights in deferred shading is proportional to the number of pixels illuminated by the light and not dependent on Scene complexity. So small point or spot lights are very cheap to render and if they are fully or partially occluded by Scene GameObjects then they are even cheaper.
Of course, lights with shadows are much more expensive than lights without shadows. In deferred shading, shadow-casting GameObjects still need to be rendered once or more for each shadow-casting light. Furthermore, the lighting shader that applies shadows has a higher rendering overhead than the one used when shadows are disabled.
When deferred shading is used, the rendering process in Unity happens in two passes:
Objects with shaders that can’t handle deferred shading are rendered after this process is complete, using the forward rendering path.
The default g-buffer layout is as follows:
So the default g-buffer layout is 160 bits/pixel (non-HDR) or 192 bits/pixel (HDR).
Emission+lighting buffer (RT3) is logarithmically encoded to provide greater dynamic range than is usually possible with an ARGB32 texture, when the Camera is not using HDR.
Note that when the Camera is using HDR rendering, then there’s no separate render target being created for Emission+lighting buffer (RT3); instead the render target that the Camera renders into (that is, the one that is passed to the image effects) is used as RT3.
The g-buffer pass renders each GameObject once. Diffuse and specular colors, surface smoothness, world space normal, and emission+ambient+reflections+lightmaps are rendered into g-buffer textures. The g-buffer textures are setup as global shader properties for later access by shaders (CameraGBufferTexture0 .. CameraGBufferTexture3 names).
The lighting pass computes lighting based on g-buffer and depth. Lighting is computed in screen space, so the time it takes to process is independent of Scene complexity. Lighting is added to the emission buffer.
Point and spot lights that do not cross the Camera’s near plane are rendered as 3D shapes, with the Z buffer’s test against the Scene enabled. This makes partially or fully occluded point and spot lights very cheap to render. Directional lights and point/spot lights that cross the near plane are rendered as fullscreen quads.
If a light has shadows enabled then they are also rendered and applied in this pass. Note that shadows do not come for “free”; shadow casters need to be rendered and a more complex light shader must be applied.
The only lighting model available is Standard. If a different model is wanted you can modify the lighting pass shader, by placing the modified version of the Internal-DeferredShading.shader file from the Built-in shaders into a folder named “Resources” in your “Assets” folder. Then go to the Edit->Project Settings->Graphics window. Changed the “Deferred” dropdown to “Custom Shader”. Then change the Shader option which appears to the shader you are using.

I'm a Celeb's Caitlyn Jenner declares transition reveal 'massive FU to haters'
Caitlyn Jenner declared her now iconic Vanity Fair cover a big ‘f*** you to haters’ as she opened up about her transition on I’m a Celebrity.
The 70-year-old reality star spoke bluntly and honestly about her transition in the public eye, which became fully realised in a 2015 issue of the fashion magazine.
Talking to her gal pals Nadine Coyle and Jacqueline Jossa, Caitlyn spoke about the landmark moment for both her and the magazine, and said that she thought it was “extraordinarily important”.
Advertisement Advertisement
‘For me, this was a big FU to the millions and millions of people out there that had said terrible things about me,’ she said. ‘And it just came out and it just shocked them.’
Cheered on by the girls, Jacqueline later said in the bush telegraph: ‘I love the fact that she talks so openly and she feels like she can trust us and speak to us so openly and she puts everything into perspective as well.
‘Like everybody goes through something. She’s like the amount of strength that woman has is amazing.’
Speaking about her transition further, Caitlyn elaborated further, including her previous attempts at transition in the 80s, which she stopped when she met and married Kris Jenner in 1991.
‘Over many, many years I had a lot but then near the end it went pretty quickly because you can do your face and your chest all at the same time which they did,’ she explained.

‘I was so confused in my life.’

‘The second time round 25 years later I was back on oestrogen obviously and they came back some but not much,’ Caitlyn continued.
‘So I really had to have them done so it is kind of past the point of no return.’
I’m a Celebrity…Get Me Out Of Here continues nightly at 9pm on ITV.

Updated: 2013.11.18
This guide explains the changes required to modify existing Graphics 1.0 code to handle some behavioral changes introduced in Graphics 2.0. By migrating your projects, you'll be able to take advantage of all the new graphics features which are not actively supported in Graphics 1.0 Compatibility Mode.
Guides for the new Graphics 2.0 features are available in Corona University. For a list of tutorials, see the Graphics 2.0 Tutorial Roundup.
The following are behavioral changes to Graphics 2.0 APIs:
In Graphics 1.0, display object constructors had a top/left parameter. These have been reinterpreted as x and y values that specify the object's center point. The original behavior of interpreting the x and y parameter as top/left is available if using V1 Compatibility Mode. You can see the difference by comparing the HelloWorld_v1
and HelloWorld_v2
samples.
The following methods and properties have been removed:
setReferencePoint
xReference
yReference
xOrigin
yOrigin
These have been replaced by anchor points, set via object.anchorX and object.anchorY. Anchors have some behavioral differences — see Understanding Transforms and Anchors for details.
Note that groups do not have anchor points. All operations are based around the group's fixed origin point.
For properties like object:setFillColor() and object:setStrokeColor(), RGBA color settings range between 0.0
and 1.0
, not between 0
and 255
. In addition, APIs that were available in Graphics 1.0 will adopt the new range by default, unless you enable V1 Compatibility Mode.
Also note that object:setTextColor()
has been deprecated. You should use object:setFillColor() on text objects instead.
This section aims to ease the migration of projects containing widgets.
In Graphics 1.0, all widgets were top-left aligned, except for newPickerWheel().
In Graphics 2.0, all widgets are center aligned for consistency. The default anchoring for all widgets is 0.5
for both the x and y coordinates.
The following changes relate to widget.newTableView():
In Graphics 2.0, the x and y properties of the table view refer to the center of the widget. This is a change from Graphics 1.0 in which the x and y properties were aligned to the top left.
In Graphics 2.0, the x and y position of the rows — when inserting objects into a row via the onRowRender
method — will refer to the center of the row.
The following example shows how your Graphics 1.0 code might look, followed by what it should look like in Graphics 2.0:
-- Graphics 1.0
local function onRowRender( event )
local phase = event.phase
local row = event.row
-- We cache the row contentWidth and contentHeight because the row bounds can change as we add children
local rowHeight = row.contentHeight
local rowWidth = row.contentWidth
local rowTitle = display.newText( row, "Row " .. row.index, 0, 0, nil, 14 )
-- Left-align the label
rowTitle.x = row.x - ( rowWidth * 0.5 ) + ( rowTitle.contentWidth * 0.5 )
rowTitle.y = rowHeight * 0.5
rowTitle:setTextColor( 0 )
end
-- Graphics 2.0 (even in V1 Compatibility Mode)
local function onRowRender( event )
local phase = event.phase
local row = event.row
-- We cache the row contentWidth and contentHeight because the row bounds can change as we add children
local rowHeight = row.contentHeight
local rowWidth = row.contentWidth
local rowTitle = display.newText( row, "Row " .. row.index, 0, 0, nil, 14 )
-- Left-align the label
rowTitle.x = 0
rowTitle.anchorX = 0
rowTitle.y = rowHeight * 0.5
rowTitle:setFillColor( 0 )
end
The following libraries and APIs have been removed in Graphics 2.0 and are not available, even in V1 Compatibility Mode:
require()
this legacy sprite module.To learn about the new Graphics 2.0 features, please read the guides in Corona University or see the Graphics 2.0 Tutorial Roundup.


Calculating expectation by plugging into the definition works in simple cases, but in other cases it can be cumbersome or lack insight. The most powerful result for calculating expectation turns out not to be the definition. It looks rather innocuous:
Let $X$ and $Y$ be two random variables defined on the same probability space. Then $$ E(X+Y) = E(X) + E(Y) $$
Before we look more closely at this result, note that we are assuming that all the expectations exist; we will do this throughout in this course.
And now note that there are no assumptions about the relation between $X$ and $Y$. They could be dependent or independent. Regardless, the expectation of the sum is the sum of the expectations. This makes the result powerful.
Additivity follows easily from the definition of $X+Y$ and the definition of expectation on the domain space. First note that the random variable $X+Y$ is the function defined by
$$ (X+Y)(\omega) = X(\omega) + Y(\omega) ~~~~ \text{for all } \omega \in \Omega $$Thus a "value of $X+Y$ weighted by the probability" can be written as
$$ (X+Y)(\omega) \cdot P(\omega) = X(\omega)P(\omega) + Y(\omega)P(\omega ) $$Sum the two sides over all $\omega \in \Omega$ to prove additivty of expecation.
By induction, additivity extends to any finite number of random variables. If $X_1, X_2, \ldots , X_n$ are random variables defined on the same probability space, then
$$ E(X_1 + X_2 + \cdots + X_n) = E(X_1) + E(X_2) + \cdots + E(X_n) $$If you are trying to find an expectation, then the way to use additivity is to write your random variable as a sum of simpler variables whose expectations you know or can calculate easily. The rest of this section consists of examples of this technique.
Let $X$ be a random variable with expectation $E(X)$ and let $Y = aX$ for some constant $a$. For example, when you change units of a random length from inches to centimeters, then $a = 2.54$.
For every $\omega \in \Omega$, we have $Y(\omega) = aX(\omega)$. So
$$ E(Y) ~ = ~ \sum_{\text{all }\omega} aX(\omega)P(\omega) ~ = ~a \sum_{\text{all }\omega} X(\omega)P(\omega ) ~ = ~ aE(X) $$Now consider the linear tranformation $W = aX + b$. This kind of transformation happens for example when you change units from Celsius to Fahreneheit ($a = 9/5$ and $b = 32$).
Then $W = Y + b$, so by additivity of expectation,
$$ E(W) = E(aX + b) = E(aX) + E(b) = aE(X) + b $$So for example, $E(2X - 3) = 2E(X) - 3$. Also $E(X/2) = E(X)/2$, and $E(1 - X) = 1 - E(X)$.
The expectation of a linear transformation of $X$ is the linear transformation of the expectation of $X$. This is a handy result as we will often be transforming variables linearly. But expectation behaves differently under non-linear transformations, as we will see in the next section.
Let $X_1, X_2, \ldots , X_n$ be a sample drawn at random from a numerical population that has mean $\mu$, and let the sample sum be $$ S_n = X_1 + X_2 + \cdots + X_n $$ Then, regardless of whether the sample was drawn with or without replacement, each $X_i$ has the same distribution as the population. This is clearly true if the sampling is with replacement, and it is true by symmetry if the sampling is without replacement as we saw in an earlier chapter.
So, regardless of whether the sample is drawn with or without replacement, $E(X_i) = \mu$ for each $i$, and hence $$ E(S_n) = E(X_1) + E(X_2) + \cdots + E(X_n) = n\mu $$
Suppose $\theta$ is a parameter of the distribution of $X$, and suppose $E(X) = \theta$. Then we say that $X$ is an unbiased estimator of $\theta$.
If an estimator is unbiased, and you use it to generate estimates repeatedely and independently, then in the long run the average of all the estimates is equal to the parameter being estimated. On average, the unbiased estimator is neither higher nor lower than the parameter. That's usually considered a good quality in an estimator.
As in the sample sum example above, let $S_n$ be the sum of a sample of size $n$ drawn from a population that has mean $\mu$. Let $A_n$ be the sample average, that is, $$ A_n = \frac{S_n}{n} $$ Then, regardless of whether the draws were made with replacement or without,
\begin{align*} E(A_n) &= \frac{E(S_n)}{n} ~~~~ \text{(linear function rule)} \\ &= \frac{n \mu}{n} ~~~~~~~~~ \text{(} E(S_n) = n\mu \text{)} \\ &= \mu \end{align*}Thus the sample mean is an unbiased estimator of the population mean.
Suppose we have a sample $X_1, X_2, \ldots , X_n$ where each variable is uniform on $1, 2, \ldots , N$ for some fixed $N$, and we are trying to estimate $N$. This was the setting in the German warplanes example in Data 8. The expectation of each of the uniform variables is $(N+1)/2$, as we have seen earlier. So if $A_n$ is the sample mean, then
$$ E(A_n) = \frac{N+1}{2} $$and so $A_n$ is not an unbiased estimator of $N$. That's not surprising because $N$ is the maximum possible value of each observation and $A_n$ should be somewhere in the middle of all the possible values.
But we can tweak $A_n$ to create an unbiased estimator of $N$. Let $A_n^* = 2A_n - 1$. Then
$$ E(A_n^*) = 2E(A_n) - 1 = 2 \cdot \frac{N+1}{2} - 1 = N $$so $A_n^*$ is an unbiased estimator of $N$.
This is a powerful method for finding expected counts. It is based on the observation that among $n$ trials, the number of "good" trials can be counted by first coding each "good" trial as 1 and each of the other trials as 0, and then adding the 1's and 0's.
If $N$ is the total number of good trials among $n$, then
$$ N = I_1 + I_2 + \cdots + I_n $$where for each $j$ in the range 1 through $n$, $I_j$ is the indicator of "the $j$th trial is good". So
\begin{align*} E(N) &= E(I_1) + E(I_2) + \cdots + E(I_n) \\ &= P(\text{Trial } 1 \text{ is good}) + P(\text{Trial } 2 \text{ is good}) + \cdots + P(\text{Trial } n \text{ is good}) \end{align*}The additivity works regardless of whether the trials are dependent or independent.
We conclude this section with three applications of the method of indicators.
Let $X$ have the binomial $(n, p)$ distribution. Then $X$ can be thought of as the number of successes in $n$ i.i.d. Bernoulli $(p)$ trials, and we can write
$$ X = I_1 + I_2 + \cdots + I_n $$where for each $j$ in the range 1 through $n$, $I_j$ is the indicator of "Trial $j$ is a success". Thus
\begin{align*} E(X) &= E(I_1) + E(I_2) + \cdots + E(I_n) ~~~~ \text{(additivity)} \\ &= np ~~~~~~~~ \text{(}E(I_j) = p \text{ for all } j \text{)} \end{align*}Thus the expected number of heads in 100 tosses of a coin is $100 \times 0.5 = 50$. The expected number of heads in 25 tosses is 12.5; remember that the expectation of an integer-valued random variable need not be an integer. The expected number of times green pockets win in 20 independent spins of the roulette wheel is $20 \times \frac{2}{38} = 1.053$, roughly.
k = np.arange(11)
probs = stats.binom.pmf(k, 10, 0.75)
bin_10_75 = Table().values(k).probability(probs)
Plot(bin_10_75, show_ev=True)
plt.title('Binomial (10, 0.75)');
Notice that we didn't use independence. Additivity of expectation works whether or not the random variables being added are independent. This will be very helpful in the next example.
Let $X$ have the hypergeometric $(N, G, n)$ distribution. Then $X$ can be thought of as the number of good elements in $n$ draws made at random without replacement from a population of $N = G+B$ elements of which $G$ are good and $B$ bad. Then
$$ X = I_1 + I_2 + \cdots + I_n $$where for each $j$ in the range 1 through $n$, $I_j$ is the indicator of "Draw $j$ results in a good element". Thus
\begin{align*} E(X) &= E(I_1) + E(I_2) + \cdots + E(I_n) ~~~~ \text{(additivity)} \\ \\ &= n\frac{G}{N} ~~~~~~~~ \text{(}E(I_j) = \frac{G}{N} \text{ for all } j \text{ by symmetry)} \end{align*}This is the same answer as for the binomial, with the population proportion of good elements $G/N$ replacing $p$.
Thus the expected number of red cards in a bridge hand of 13 cards is $13 \times \frac{26}{52} = 6.5$. The expected number of Independent voters in a simple random sample of 200 people drawn from a population in which 10% of the voters are Independent is $200 \times 0.1 = 20$. These answers are intuitively clear, and we now have a theoretical justification for them.
# Number of hearts in a poker hand
N = 52
G = 13
n = 5
k = np.arange(6)
probs = stats.hypergeom.pmf(k, N, G, n)
hyp_dist = Table().values(k).probability(probs)
Plot(hyp_dist, show_ev=True)
plt.title('Hypergeometric (N=52, G=13, n=5)');
A population consists of four classes of individuals, in the proportions 0.4, 0.3, 0.2, and 0.1. A random sample of $n$ individuals is chosen so that the choices are mutually independent. What is the expected number of classes that are missing in the sample?
If $M$ is the number of missing classes, then
$$ M = I_1 + I_2 + I_3 + I_4 $$where for each $j$, $I_j$ is the indicator of "Class $j$ is missing in the sample".
For Class $j$ to be missing in the sample, all $n$ selected individuals have to be from the other classes. Thus
$$ E(M) = E(I_1) + E(I_2) + E(I_3) + E(I_4) = 0.6^n + 0.7^n + 0.8^n + 0.9^n $$The four indicators aren't independent but that doesn't affect the additivity of expectation.


While the overall interfaces for MQTT and HTTP are kept relatively in sync, the node and browser flavors of the AWS CRT have different capabilities. For this reason, we generate separate documentation for each flavor.


Return true if the forward compatibility window has expired.
tf.compat.v1.compat.forward_compatible
tf.compat.v2.compat.forward_compatible
tf.compat.forward_compatible( year, month, day )
Forward-compatibility refers to scenarios where the producer of a TensorFlow model (a GraphDef or SavedModel) is compiled against a version of the TensorFlow library newer than what the consumer was compiled against. The "producer" is typically a Python program that constructs and trains a model while the "consumer" is typically another program that loads and serves the model.
TensorFlow has been supporting a 3 week forward-compatibility window for programs compiled from source at HEAD.
For example, consider the case where a new operation MyNewAwesomeAdd
is
created with the intent of replacing the implementation of an existing Python
wrapper - tf.add
. The Python wrapper implementation should change from
something like:
def add(inputs, name=None): return gen_math_ops.add(inputs, name)
to:
from tensorflow.python.compat import compat def add(inputs, name=None): if compat.forward_compatible(year, month, day): # Can use the awesome new implementation. return gen_math_ops.my_new_awesome_add(inputs, name) # To maintain forward compatibiltiy, use the old implementation. return gen_math_ops.add(inputs, name)
Where year
, month
, and day
specify the date beyond which binaries
that consume a model are expected to have been updated to include the
new operations. This date is typically at least 3 weeks beyond the date
the code that adds the new operation is committed.
year
: A year (e.g., 2018). Must be an int
.month
: A month (1 <= month <= 12) in year. Must be an int
.day
: A day (1 <= day <= 31, or 30, or 29, or 28) in month. Must be an
int
.True if the caller can expect that serialized TensorFlow graphs produced can be consumed by programs that are compiled with the TensorFlow library source code after (year, month, day).

Labour manifesto will be 'significantly' more radical than in 2017
by Stefan BosciaLabour insiders have branded the party’s election manifesto as “significantly” further to the left of the party’s 2017 offering.
Labour will release its General Election manifesto on Thursday, after holding a Clause V meeting of senior party figures and union bosses last night.
Read more: Jeremy Corbyn labels Labour nationalisation plans as very modest
Labour leader Jeremy Corbyn said the manifesto was agreed upon unanimously and he was “very, very proud” of the “transformative document” as he was leaving the meeting last night.
The manifesto reportedly includes banning people from working more than 48 hours a week, A Right to Food Act to control prices, an extension of the sugar tax and a tax on oil companies, according to the Mail on Sunday.
Labour insiders have also confirmed the party’s plans to nationalise water and energy utilities, the railways, Royal Mail and BT.
When party chairman Ian Lavery was asked by the the Mail on Sunday if the manifesto was more radical than from the 2017 election, he confirmed that it was.
“We sorted out all the problems and it was fantastic,” he said.
“This is the best manifesto you are likely to see.”
Conservative international trade secretary Liz Truss branded it as a “Marxist manifesto” that would “plunge this country into extortionate debt and deliver division and delay”.
Senior Labour policy advisor Andrew Fisher wrote the manifesto, just months after saying he “no longer had faith” the party could succeed.
Fisher was dismayed at the “lack of professionalism, competence and human decency” from those in Corbyn’s team.
Other manifesto policies already announced include free dental checks for everybody in the UK, a second Brexit referendum and a £40bn increase in health spending over five years.
One point of contention among Labour figures is the party’s position on ending freedom of movement in its negotiated Brexit deal.

Unite the Union boss Len McCluskey recently said Labour needed to end freedom of movement within the EU.
Meanwhile, other major party figures, such as Momentum’s Jon Lansman, have said the opposite.

The App API handles high level App state and events.
For example, this API emits events when the app enters and leaves the foreground, handles deeplinks, opens other apps, and manages persisted plugin state.
canOpenUrl
To use canOpenUrl
, you need to set the URL schemes your app will query for in LSApplicationQueriesSchemes
in Info.plist
.
Read more about LSApplicationQueriesSchemes and configuring Info.plist.
import { Plugins, AppState } from '@capacitor/core';
const { App } = Plugins;
App.addListener('appStateChange', (state: AppState) => {
// state.isActive contains the active state
console.log('App state changed. Is active?', state.isActive);
});
// Listen for serious plugin errors
App.addListener('pluginError', (info: any) => {
console.error('There was a serious error with a plugin', err, info);
});
var ret = await App.canOpenUrl({ url: 'com.getcapacitor.myapp' });
console.log('Can open url: ', ret.value);
ret = await App.openUrl({ url: 'com.getcapacitor.myapp://page?id=ionicframework' });
console.log('Open url response: ', ret);
ret = await App.getLaunchUrl();
if(ret && ret.url) {
console.log('App opened with URL: ' + ret.url);
}
console.log('Launch url: ', ret);
App.addListener('appUrlOpen', (data: any) => {
console.log('App opened with URL: ' + data.url);
});
App.addListener('appRestoredResult', (data: any) => {
console.log('Restored state:', data);
});
On Android, due to memory constraints on low-end devices, it's possible that, if your app launches a new activity, your app will be terminated by the operating system in order to reduce memory consumption.
For example, that means the Camera
API, which launches a new Activity to take a photo, may not be able to return data back to your app.
To avoid this, Capacitor stores all restored activity results on launch. You should add a listener for appRestoredResult
in order to handle any
plugin call results that were delivered when your app was not running.
Once you have that result (if any), you can update the UI to restore a logical experience for the user, such as navigating or selecting the proper tab.
We recommend every Android app using plugins that rely on external Activities (for example, Camera) to have this event and process handled.

SpreadSheet Format (SSF) is a pure-JS library to format data using ECMA-376 spreadsheet format codes (like those used in Microsoft Excel)
This is written in voc – see ssf.md for code.
To build: voc ssf.md
In the browser:
<script src="ssf.js"></script>
In node:
var SSF = require('ssf');
The script will manipulate module.exports
if available (e.g. in a CommonJS require
context). This is not always desirable. To prevent the behavior, define DO_NOT_EXPORT_SSF
:
.load(fmt, idx)
sets custom formats (generally indices above 164
).
.format(fmt, val, opts)
formats val
using the format fmt
. If fmt
is of type number
, the internal table (and custom formats) will be used. If fmt
is a literal format, then it will be parsed and evaluated.
.parse_date_code(val, opts)
parses val
as date code and returns object:
D,T
: Date ([val]
) Time ({val}
)y,m,d
: Year, Month, DayH,M,S,u
: (0-23)Hour, Minute, Second, Sub-secondq
: Day of Week (0=Sunday, 1=Monday, …, 5=Friday, 6=Saturday).get_table()
gets the internal format table (number to format mapping).
.load_table(table)
sets the internal format table.
Format code 14 in the spec is broken; the correct format is ‘mm/dd/yy’ (dashes, not spaces)

This document introduces you to Rmagine’s image filter functions, and shows you how to apply them to images.
Here’s an example photo we’ll be using taken at Coronado Beach, San Diego:
This function produces an image with strong visual distortion intended to create a tunnel or pincushion effect.
This function produces an image with different user-specified colour distortions.
This function identifies edges by looking at where the image brightness changes sharply, and produces a black and white image highlighting the locations of these edges.
This function produces an image with reduced brightness around the periphery compared to the image center.
image_path
: file path of the input image (string)strength
: parameter for strength of the dimming effect (double, optional). If not specified, defaults to 1.0

You will more typically hear “data is” but that more often refers to information, sometimes even statistical summaries of data sets, than to observations collected as part of a study, suggesting the confusion of this term in the general public. We will explore a data set in Chapter 5 related to perceptions of this issue collected by researchers at http://fivethirtyeight.com/.↩
Either try to remember “data is a plural word” or replace “data” with “things” in your sentence and consider whether it sounds right.↩
As noted previously, we reserve the term “effect” for situations where random assignment allows us to consider causality as the reason for the differences in the response variable among levels of the explanatory variable, but this is only the case if we find evidence against the null hypothesis of no difference in the groups.↩
If you’ve taken calculus, you will know that the curve is being constructed so that the integral from \(-\infty\) to \(\infty\) is 1. If you don’t know calculus, think of a rectangle with area of 1 based on its height and width. These cover the same area but the top of the region wiggles.↩
Jittering typically involves adding random variability to each observation that is uniformly distributed in a range determined based on the spacing of the observation. This means that if you re-run the
jitter
function, the results will change. For more details, typehelp(jitter)
in the console in RStudio.↩Remember the bell-shaped curve you encountered in introductory statistics? If not, you can see some at https://en.wikipedia.org/wiki/Normal_distribution↩
Well, you can use other colors (try “lightblue” for example), but I think bisque looks nice in these plots.↩
It is also possible to use the
subset
function to eliminate observations that do not have a particular trait andsubset(MockJury,subset=NotBeautiful)
would provide the same result asMockJury[MockJury$NotBeautiful,]
did here.↩The hypothesis of no difference that is typically generated in the hopes of being rejected in favor of the alternative hypothesis, which contains the sort of difference that is of interest in the application.↩
The null model is the statistical model that is implied by the chosen null hypothesis. Here, a null hypothesis of no difference translates to having a model with the same mean for both groups.↩
We’ll see the
shuffle
function in a more common usage below; while the code to generatePerm1
is provided, it isn’t something to worry about right now.↩P-values are the probability of obtaining a result as extreme as or more extreme than we observed given that the null hypothesis is true.↩
In statistics, vectors are one dimensional lists of numeric elements – basically a column from a matrix or our tibble.↩
We often say “under” in statistics and we mean “given that the following is true”.↩
This is a fancy way of saying “in advance”, here in advance of seeing the observations.↩
Statistically, a conservative method is one that provides less chance of rejecting the null hypothesis in comparison to some other method or less than some pre-defined standard.↩
We’ll leave the discussion of the CLT to your previous statistics coursework or an internet search. For this material, just remember that it has something to do with distributions looking more normal as the sample size increases.↩
On exams, you will be asked to describe the area of interest, sketch a picture of the area of interest, and/or note the distribution you would use.↩
In some studies, the same subject might be measured in both conditions and this violates the assumptions of this procedure.↩
Only male and female were provided as options on the survey.↩
The
as.numeric
function is also used here. It really isn’t important but makes sure the output oftable
is sorted by observation number by first converting the orig.id variable into a numeric vector.↩In any bootstrap sample, about 1/3 of the observations are not used at all.↩
There are actually many ways to use this information to make a confidence interval. We are using the simplest method that is called the “percentile” method.↩
When hypothesis tests “work well” they have high power to detect differences while having Type I error rates that are close to what we choose a priori. When confidence intervals “work well”, they contain the true parameter value in repeated random samples at around the selected confidence level. ↩
We will often use this term to mean from the component summary information – not that you need to go back to the data set and calculate the means and standard deviations.↩
We rounded the means a little and that caused the small difference in results.↩
You can correctly call octothorpes number symbols or, in the twitter verse, hashtags. For more on this symbol, see “http://blog.dictionary.com/octothorpe/”. Even after reading this, I call them number symbols.↩
