We can read the p-value from the table for Race (0.00555), which tests the same null and alternative hypothesis as stated in a. This is because that p-value represents: \[ H_{0}: \beta_{Race} = 0 \] \[ H_{1}: \beta_{Race} \neq 0 \]
Both of which are conditional on District (holding District constant).
The information we can glean from a model based analysis, is that we can determine the effect size and direction of Race, holding District constant, as opposed to whether or not an effect exists.

## [1] 0.3560812
Since this is \(>\alpha=0.05\), we can remove the 2nd order interaction term from the model.
Without seeing the regression output, I’d assume the \(S*W\) term has the highest p-value, and therefore would be dropped next. As well, it has the highest AIC of the 3 models.
I would go to model 4b \((W+C*S)\) as it has the highest AIC of the two models.
pchisq(q = 186.61 - 177.61, df = 166 - 160, lower.tail = FALSE)
## [1] 0.1735781
Since this is \(>\alpha=0.05\), we can remove the 1st order interaction term from the model.
\(C+S+W\) is preferred, as it has the smallest AIC.
The model with the 4 main predictors is the preferred model, as it has the smallest AIC (637.5), of the 4 models.
Let: \(\theta\) be the odds in favor of smoking.
\[\begin{equation} \ln(\theta) = \hat{\beta}_{0} \end{equation}\] \[\begin{equation} \ln(\theta) = \hat{\beta}_{0} + \hat{\beta}_{1}E/I + \hat{\beta}_{2}S/N + \hat{\beta}_{3}T/F + \hat{\beta}_{4}J/P \end{equation}\] \[ \ln(\theta) = \hat{\beta}_{0} + \hat{\beta}_{1}E/I + \hat{\beta}_{2}S/N + \hat{\beta}_{3}T/F + \hat{\beta}_{4}J/P + \hat{\beta}_{5}E/I\times S/N + \hat{\beta}_{6}E/I\times T/F + \] \[\begin{equation} \hat{\beta}_{7}E/I\times J/P + \hat{\beta}_{8}S/N\times T/F + \hat{\beta}_{9}S/N\times J/P + \hat{\beta}_{10}T/F\times J/P \end{equation}\] \[ \ln(\theta) = \hat{\beta}_{0} + \hat{\beta}_{1}E/I + \hat{\beta}_{2}S/N + \hat{\beta}_{3}T/F + \hat{\beta}_{4}J/P + \hat{\beta}_{5}E/I\times S/N + \hat{\beta}_{6}E/I\times T/F + \] \[ \hat{\beta}_{7}E/I\times J/P + \hat{\beta}_{8}S/N\times T/F + \hat{\beta}_{9}S/N\times J/P + \hat{\beta}_{10}T/F\times J/P + \hat{\beta}_{11}E/I\times S/N\times T/F + \hat{\beta}_{12}E/I\times S/N\times J/P + \] \[\begin{equation} \hat{\beta}_{13}E/I\times T/F\times J/P + \hat{\beta}_{14}S/N\times T/F\times J/P \end{equation}\]\[ AIC_{(1)} = 2(1) + 1130.23 = 1132.23, AIC_{(2)} = 2(5) + 1124.86 = 1134.86 \] \[ AIC_{(3)} = 2(11) + 1119.87 = 1141.87, AIC_{(4)} = 2(15) + 1116.47 = 1146.47 \]
Since (1) has the smallest AIC value, it is the preferred model.
Probably not, as neither the sensitivity nor the specificity are particularly high, implying that the model doesn’t have a high True Positive Rate, or high True Negative Rate. As well, with an AUC of 0.55, our model is only slightly better than randomly guessing. As such, knowledge of a person’s personality type does not help you predict whether or not someone is a frequent smoker.

Let \(\theta:\) be the odds in favour of staying missing after a year. \[ x_{1} = \begin{cases} 1, Age\geq19 \\ 0, Age<19 \end{cases} \] \[ x_{2} = \begin{cases} 1, 14<Age<18 \\ 0, Age<14 \cup Age>18 \end{cases} \] \[ x_{3} = \begin{cases} 1, Male \\ 0, Female \end{cases} \] \[ \ln(\theta) = -4.1845 + 1.1279x_{1} - 0.1980x_{2} - 0.3803x_{3} \]
The log odds in favour increase on average by 1.1279, if the person is 19 or older, decrease on average by 0.1980 if they are between 14 and 18, and decrease on average by 0.3803 if they are male.
The Cochran-Mantel-Haenszel Test yields a p-value of \(1.085\times10^{-5}<\alpha=0.05\), rejecting the null hypothesis of independence, contingent on Age. Based on the sample assume some dependency exists between Gender and Missing Status, contingent on Age.
Both the \(\chi^{2}\) and \(G^{2}\) yield values of \(\approx0.1\), giving p-values of \(>0.95\), therefore failing to reject the null hypothesis that the model is a good fit for the data, based on the sample.

1. Quick Start (The Absolute Minimum)
If you are interested playing around with MRaster
as quickly as possible, then this section is for you.
The first step is to download MRaster
. You can grab the zip file, or you can simply
clone the repository with GIT like this:
git clone 'https://github.com/richmit/mraster.git'
Once you have it downloaded, make note of the "lib
" folder within the repository. This folder contains everything you need to develop with MRaster
, and you
can simply put your code right in that directory. So let's create a file called "hello.cpp
" right inside the "lib
" directory with the following content:
#include "ramCanvas.hpp" // The main MRaster include int main(void) { mjr::ramCanvas3c8b theRamCanvas(1024, 1024); // Create a canvas object for(int y=0;y<theRamCanvas.getNumPixY();y++) // Run over the rows for(int x=0;x<theRamCanvas.getNumPixX();x++) // and columns of the image theRamCanvas.drawPoint(x, y, mjr::color3c8b::csCColdeRainbow::c(x+y)); // Pick a "rainbow" color for the point theRamCanvas.writeTIFFfile("hello.tiff"); // Write out our image to disk }
Now we can compile it with GCC like this:
g++ -m64 -std=gnu++20 hello.cpp -o hello2
Now you can run it, and take a look at the file it created ("hello.tiff
"):
That's it! How easy was that?
1.1. FAQ for people not using cmake
1.1.1. Q1: How do I get advanced TIFF reader support without cmake
?
A: If you have
libtiff
installed in a standard location, then you can probably just add "=-DTIFF_FOUND" to the compile command like this:g++ -DTIFF_FOUND -m64 --std=gcc++20 hello.cpp -o helloPlease note that advanced TIFF reader is only required to read TIFF files.
MRaster
can save TIFF, TGA, and MRAW files without any external library support.
1.1.2. Q2: What's up with "-std=gcc++20
" instead of "-std=c++20
"?
A:
MRaster
works just fine with standard C++20 compilers. The "-std=gcc++20
" option enables specific features of GCC that makeMRaster
better. In particular, it enables 128-bit integers on platforms that support it – allowing, for example, a very high performance floating point RGBA image format. If you want to turn off 128-bit integers, and use pure C++20 instead with GCC, then you can use a command line like this:g++ -DMJR_LOOK_FOR_128_BIT_TYPES=0 -m64 --std=c++20 hello.cpp -o hello
1.1.3. Q3: I got some weird errors about bit_cast
. What's up?
Probably your compiler is too old to support that part of the C++ standard. One of the advantages of using cmake
is that it tries to detect this issue. Without cmake
, you need to add the following
to your compile command (or get a better compiler):
-DMISSING_P0476R2=1
1.1.4. Q4: I got some weird errors about complex numbers and std::pow
? What's up?

2. Playing With MRaster
's Example Programs
The source code for the example programs is located in the "examples
" directory. MRaster
ships with a cmake
build system that should be able to
interrogate your environment, and produce make files for your OS. To build the example programs:
- Change directory to the root of the git repository (you should see "
lib
" & "examples
" directories. - Create a "
build
" directory – cmake builds outside of the source trees. - Change directory to the build directory
- Use
cmake
to generate make files for your system - Build the examples
- Play with the examples
A typical shell session following the steps outlined above might look like this:
rm -rf build mkdir build cd build cmake -G 'MSYS Makefiles' .. # For Windows running MSYS2. Remove the "-G 'MSYS Makefiles'" bit for other platforms. make
Note cmake
can take several options like the "-G
" option mentioned in the example above. For more information on options related to MRaster
, take a look
at the "configure.sh
" script in the root directory of the git repository.
3. Using MRaster
's cmake
Configuration
For many MRaster
users, cmake
is an unfamiliar tool. Some of them decide to directly use MRaster
's cmake
infrastructure, using the "examples
"
directory as a template for the code they produce. This can be a nice way for people new to cmake
to get an idea of how it works; however, I have to warn
you: I'm really a cmake
novice! You might just pick up some cmake
bad habits looking at my CMakeLists.txt
file! :)
If you want to use the MRaster
cmake
infrastructure, the easiest path is to put your code in the "examples"
directory. Next we need to add your code to
the "CMakeLists.txt
" file. Look for lines like these:
set(TARGETS_REQ_NONE "apollony" "apomorph" ... set(TARGETS_REQ_MRRL "color_lut_indexed" "color_lut_rainbows" ... set(TARGETS_REQ_OPENGL "glut_image") set(TARGETS_REQ_TIFF "brownianDiffusion" "dlaBrownian" ... set(TARGETS_REQ_OPENMP "mandelbrot_bm_cplx_openmp") set(TARGETS_REQ_BTEST "utest_foo" "utest_color_types_ia64nGCC" ... set(TARGETS_REQ_PNG ) set(TARGETS_REQ_IM )
Each of these lines are a list of source files that require various external dependencies. In general you should always add your source file (minus the
".cpp
" extension) to the "TARGETS_REQ_MRRL
" list. If your program needs the advanced TIFF reader, then also add it to the "TARGETS_REQ_TIFF
" list as
well. Now we are ready to go:
- Create a directory called "
build
" in the root of the git repository - Change directory the "
build
" directory - Use
cmake
to generate make files - Build your program!
These steps might look like this:
rm -rf build mkdir build cd build cmake -G 'MSYS Makefiles' .. make your_program
4. Platform Notes
I write these notes on 2022-08-28 as a guide for making the most of MRaster
on various platforms given the rather uneven nature of C++20 support in the
wild. I expect these notes will be out of date by the time I hit the publish button. ;)
4.1. Windows 11 with MSYS2 GCC 12.1.0
Everything works with the following cmake:
cmake -G 'MSYS Makefiles' -DCMAKE_CXX_COMPILER=g++ ..
4.2. Windows 11 with MSYS2 clang 14.0.6
Everything works with the following cmake:
cmake -G 'MSYS Makefiles' -DCMAKE_CXX_COMPILER=clang++ ..
4.3. Windows 11 with MSYS2 cmake and Visual Studio 2022 Community Edition
This method works, but you won't get any external dependencies like GLUT
, SDL2
, libTIFF
, boost
, etc… But, you will get enough to run many of the examples.
From the MSYS2 shell, we can run cmake like this:
cmake -G 'Visual Studio 17 2022' ..
Then open up the directory with explorer, and double click on one of the project files. That will open up VS, and you can work the project.
4.4. Windows 11 with Visual Studio 2022 Community Edition
Everything works, but it's harder to get set up. Simply fire up VS, and open the folder with the CMakeLists.txt
file in it. VS will detect a cmake
project. Next use vcpkg to install GLUT
, SDL2
, libTIFF
, & boost
. Update CMakeLists.txt
as described
here. Refresh the cmake
, and you should be able to build.
4.5. Mac OS X Monterey 12.5.1 with Homebrew GCC 12.1.0
I had trouble getting boost
to work, but everything else seems OK. Note the -DGLUT_glut_LIBRARY
option – this is required to direct cmake
to use the
Apple provided GLUT
instead of freeglut
from homebrew.
Here is what I installed via Homebrew:
brew install gcc brew install cmake brew install sdl2 brew install doxygen brew install libtiff brew install boost
And I used the following cmake:
cmake -DCMAKE_CXX_COMPILER=g++-12 -DGLUT_glut_LIBRARY=/System/Library/Frameworks/GLUT.framework ..
4.6. Mac OS X Monterey 12.5.1 with Apple clang 13.1.6
Right now clang
doesn't have support for floating point template parameters, and thus the templates csPLY_tpl
& csCubeHelix_tpl
are not available.
This also means that examples using these features are not built:
color_lut_poly.cpp
color_lut_docs.cpp
color_lut_cubehelix.cpp
heart2022.cpp
In addition, the Apple version of clang
is missing the C++20 feature bit_cast
. Right now MRaster
has conditional compilation sections removing those
features when using this compiler. Hopefully Apple will have better C++20 support soon.
Lastly, note the -DGLUT_glut_LIBRARY
option – this is required to direct cmake
to use the Apple provided GLUT
instead of freeglut
from homebrew.
cmake -DCMAKE_CXX_COMPILER=clang++ -DGLUT_glut_LIBRARY=/System/Library/Frameworks/GLUT.framework ..
4.7. Debian bullseye 11.4
For reference, some of my config files:
Here is my /etc/apt/sources.list
file:
deb http://deb.debian.org/debian bullseye main deb http://deb.debian.org/debian bullseye-updates main deb http://security.debian.org/debian-security bullseye-security main deb http://ftp.debian.org/debian bullseye-backports main deb http://mirrors.xmission.com/debian/ testing main non-free contrib deb http://http.us.debian.org/debian testing main contrib non-free deb http://ftp.us.debian.org/debian testing main non-free contrib
Here is my /etc/apt/preferences
file:
Package: * Pin: release a=testing Pin-Priority: 490
4.7.1. Debian bullseye 11.4 with GCC 10.2.1
This is the stock compiler that comes with bullseye. It's a bit old, and is missing support for both floating point template arguments and bit_cast
.
You can install everything you might want for MRaster
like so:
sudo apt update sudo apt upgrade sudo apt-get install build-essential libsdl2-dev libtiff-dev freeglut3-dev doxygen libboost-all-dev sudo apt-get install povray ffmpeg imagemagick sudo apt install cmake/bullseye-backports
Now you can use the following cmake
command:
cmake ..
4.7.2. Debian bullseye 11.4 with GCC 11.3
With this newer compiler all MRaster
features are supported.
This is the compiler currently in the bullseye testing
channel. You will need the stuff installed in the previous section as well as this compiler. You
can install it all with the following:
sudo apt update sudo apt upgrade sudo apt-get install build-essential libsdl2-dev libtiff-dev freeglut3-dev doxygen libboost-all-dev sudo apt-get install povray ffmpeg imagemagick sudo apt install cmake/bullseye-backports sudo apt install -t testing g++-11 gcc-11
Now you can use the following cmake
command:
cmake -DCMAKE_CXX_COMPILER=g++-11 ..
5. FAQ
5.1. Q1: What's up with "-std=gcc++20
" instead of "-std=c++20
"?
A:
MRaster
works just fine with standard C++20 compilers. The "-std=gcc++20
" option enables specific features of GCC that makeMRaster
better. In particular, it enables 128-bit integers on platforms that support it – allowing, for example, a very high performance floating point RGBA image format. If you want to turn off 128-bit integers, and use pure C++20 instead with GCC, then you can use a command line like this:g++ -DMJR_LOOK_FOR_128_BIT_TYPES=0 -m64 --std=c++20 hello.cpp -o hello
5.2. Q2: The examples seem to be missing standard/system include files
A: It is good form to place necessary includes in each file that needs them; however, I have violated this sound practice in the examples shipped with
MRaster
. In particular, because theramCanvasTpl.hpp
andcolorTpl.hpp
files include just about everything the examples need I have tended to shorten up the examples and depend on the includes from these headers.


What is Scorigami?
Scorigami is a concept thought up by Jon Bois. It is the art of building final scores that have never happened before in NFL history. Due to the unique nature of how points are scored in (American) Football, where it is impossible to score 1 point on its own, as well as the rarity of the 2 point safety and 8 point touchdown and 2 point conversion, there are a lot of scores that are possible, but have never happened. For more info, check out the video made by Jon Bois about Scorigami below.

Week 1
There has to be a easier way to merge files
09/14/15
There is a lot I can write about Week 1, but I will keep it short since I am behind on work. Maybe I will come back and write more about it later. We learned about Git and Git Hub and how they work together and we can use Terminal to push and merge changes together. There are many benefits to using Github since a devolper can keep track of the many changes that are being made on files. They can also make their own branches and edit them and then re merge them to update the remote files. This way none of the master files get messed up. That is the main lesson I learned this week, I will try to come back and add more about it when I can.

Thug tried to hurl pregnant girlfriend out window after man liked Facebook photo
A violent bully subjected his pregnant girlfriend to two vicious attacks where she was stripped naked, punched in the gut, and nearly thrown out of a window.
Ashley Brazier, 31, of Whitstable in Kent, picked up his 7st 2lbs partner and tried to chuck her out the window after he noticed a man had ‘liked’ her Facebook photo.
Brazier, who has a history of harassment, battery, and criminal damage, only failed because she managed to extend her body across the frame and resist.
But her boyfriend’s anger only intensified and he pinned her to a wall by the throat with such force, he lifted her from the floor.
He then chased her in a ‘petrifying’ game of ‘cat and mouse’, prosecutor Amy Nicholson told Canterbury Crown Court this week.
Brazier then struck the pregnant victim in the face with her phone after accusing her of having an affair.
Advertisement Advertisement
The court also heard how a ‘spiteful and cruel’ Brazier had previously thrown ‘away her father’s ashes’ Ms Nicholson said.
She added: ‘What happened has ruined her life.’
Brazier was jailed for three years and nine months for grievous bodily harm and actual bodily harm.
Brazier has 41 previous convictions, including two for harassment, six for battery, 10 for criminal damage, as well as multiple breaches of court orders.
During the attack Brazier repeatedly spat in his victim’s face as she fought to escape. He slapped her so hard her ear rang.
Brazier punched his girlfriend in the gut, dislodging her rib and puncturing her lung – which doctors later had to inflate twice.
He then stripped her and locked her out, which Judge Rupert Lowe described as his ‘signature attack’.
Brazier only stopped when he realised the extent of her injuries.
She was sent to the Queen Elizabeth The Queen Mother Hospital in Margate, Kent, where doctors installed a drainage tap.
The victim did not know she was in the early stages of pregnancy at the time of the assault.
In an earlier attack, Brazier was suspicious of one of his partner’s texts while he was out drinking with friends in Ramsgate, Kent.

Judge Rupert Lowe scalded Brazier for his campaign of violence and humiliation, adding that he posed a ‘significant risk to the public’ but could not impose an extended sentence because his powers were restricted.

[Gecode] Memory leak in the sets
Christian Schulte
schulte at imit.kth.se
Thu Sep 2 10:41:40 CEST 2004
Dear all,
I would like to clarify the problem here: it is not about how destructors
are handeled, it is about the simple point that space-allocated memory is
just not useful for temporary data structures. This is absolutely clear.

Subject: [Gecode] Memory leak in the sets
Hi.
Unfortunately we have a memory leak in the n-ary set propagators, and I have
no idea how to fix it: some n-ary propagators keep a GrowingSet containing
e.g. the union of the already determined variables. The memory for this set
of course comes from the space, but it is never freed. We cannot give a
destructor for IntegerSets because that would need the home space (for
dispose of a free list).
I have taken care of all the other intermediate results we store in integer
sets, although this is also not optimal - you have to dispose the sets
manually when you don't use them any longer.
Maybe we should think of a different data structure for these intermediates.

Housing
The MD4SG Housing working group brings together researchers from the fields of computer science, operations research, and economics who share a deep interest in affordable housing policy. We study how recent techniques in mechanism design, algorithmic game theory, machine learning, and econometrics can shed light on affordable housing issues such as efficiently allocating affordable housing services, enforcing fair housing laws, and reducing housing instability. More broadly, we are interested in how to design incentives to increase fairness and efficiency in housing markets.

Well maybe not a celebrity or a contestant, but I am a guest contributor over at a fun site that is mainly small camera focused (forgive the double entendre - I can never resist, even though you slouches never pick them up). Check it if you have a few. Nice bunch of folks that care a whole lot about their images.

Steve Martin's 1991 version of Father of the Bride was one of the best comedies of recent years and it wasn't because the movie had big laughs (although it did) but because of the movies warm, likeable portrait of normal, everyday middle-class life. And Steve Martin isn't just a great comedian, he's also a great actor whose equally terrific in comic, heartwarming and dramatic scenes (see last years virtually unnoticed A Simple Twist of Fate). Father of the Bride 2 is a good sequel for many different reasons but he is the main one. While the movie mostly just requires his verbal and physical comic skills, he does get to display his dramatic reach here a couple times. One particularly beautiful scene comes near the end where he is holding two newborn babies. He doesn't say a word during the scene but it's a tribute to his acting skills that you know just what he's thinking. What's also good about this sequel is that it actually continues the first movie instead of just repeating it, like we saw, for example, in Home Alone 2. Martin's character, George Banks, has finally recovered from his daughters wedding and is ready for some relaxation time when his daughter (Kimberly Williams) now hits him with the news that she is pregnant. And as if thats not enough, he soon finds out that his wife (Diane Keaton) is also expecting. In an attempt to stay young and start fresh, George decides to sell the familys beloved home much to the dismay of the rest of the family. This leads to the movies only (hardly major) flaw. The person who buys the Banks home is a Middle Eastern caracture played by SCTV's Eugene Levy (who also had a cameo in the first film playing a different character). That kind of ethnic swipe seems like it would be more at home in a Jerky Boys comedy than in this friendly, family oriented film. Martin Short also returns as Franc Egglehoffer, the crazy wedding planner from the first film who speaks in an indecipherable accent that seems to be understood by everyone but George. This time he is both a decorator for the new babys nursery and as an aerobics instructor for the two pregnant women. He and Martin also have a funny "male bonding" moment near the end of the film. But still whats most appealing about both films is the way director Charles Shyer and writer Nancy Meyers seem to balance the warm moments and the comic ones. Its those moments, like the one with the two babies, that you will take home with you afterwards.

JSX in Depth
JSX is just JavaScript. It just happens to look like HTML. A JSX tag is a function that creates an HTML tag with attributes and children.
Let's take an example:
// functional component:
function Title(title) {
return (
{title}
)
}
// The functional component as a custom JSX tag:
<Title {Hello, world!}/>
// The same tag as a hyperscript function:
h('h1', {title: 'The title'}, 'Hello, world!')
// The tag produces the following virtual node:
{
type: "h1",
props: {title: "The title"},
children: ["Hello, world!"]
}
// The virtual node gets converted into a DOM node:

Hello, world!

JSX is just a simplier way to represent the DOM nodes your component needs to create. Because it is JavaScript, you can use it with normal JavaScript expressions to evaluate and parse the data that you need to display.
Composition
Although you can define simple JSX tags, the real strength of JSX is that it lets you you simple JSX elements combined together to create more complex ones. These parts can even be in separate files, allowing for their reuse through your app or in other apps.
As an example of composition, let's create a dialog box. We are going to start with the dialog itself, which is just the border around the content:
function FancyBorder(props) {
console.log(props)
return (

)
}
// Inject the dialog in the document:
mount(<FancyBorder />), 'body'
We'll update this to allow the user to pass in the color as a prop:
function FancyBorder(props) {
console.log(props)
return (

)
}
// Inject the dialog in the document:
mount(<FancyBorder color="maroon" />,'body')
So, now we have a very basic function component. But we want to be able to render it with a child component. Here is the child:
function DialogMessage() {
return (

Welcome

Thank you for visiting our time machine!

)
}
Now, the question is, how can we get the child component into the dialog box? As you saw above, we passed the color to the dialog box as a prop. We can do the same with our child component. We'll make a slight modification to FancyBorder so that it can received arbitrary child nodes. We'll do that by passing a second parameter to the function, which we'll call children
:
function FancyBorder(props, children) {
console.log(props)
return (

{children}

)
}
With the FancyBorder
component set to capture a children
prop, we can pass in our DialogMessage
component when we render FancyBorder
:
See the Pen Composition by Robert Biggs (@rbiggs) on CodePen.
Through composition we are able to add child components to other components to build more complex solutions.
Composition with Class Components
We can use this same technique with class components. We are going to show how to use composition of JSX functional components to create a class component. We are going to start with the same FancyBorder
component we made earlier:
function FancyBorder(props, children) {
console.log(props)
return (

{children}

)
}
We'll use this as the base for our new component. We want to have a dialog where the user can enter a name, and after tapping a button, gets a greeting. By the way, this will be a signup for the Time Travel Program.
Issues to Deal With
Because we are going to be passing props down from a class component to child components that are function, there will be some wrapping of the props at each level. Kind of annoying, but its what JSX does in this situation. Therefore we will need to use .props
to get at values in places where you would expect too.
Here's the basic setup for our class component:
class SignUpDialog extends Component {
constructor(props) {
super(props)
this.container = 'section'
this.state = {
login: '',
title:"Time Travel Program",
message:"How should we refer to you?"
}
}
render(props) {
return (
return (
<FancyBorder color='maroon'>
<DialogChildren {...{title: props.title, message: props.message, component: this}}/>
</FancyBorder>
)
}
}
So, we have a class component that returns our FancyBorder
component, while passing it props for color
and children
. Notice how dialogChildren
is get passed props and this
. That will pass a reference of the class component down to the children so they have access to the parent's properties. In particular we want to expose the parent's state and event methods to the children.
We'll need a component to create the default title and greetign for the dialog. We'll call that component Dialog
. We'll also need a component to be the form where the user enters there name an taps a button to submit it. We'll call that FormInputs
. Then we'll create a function called dialogChildren
which will combine these to. We'll pass this function to the FancyBorder
component as its children
prop. And, we will add some methods and events to make name submission work. Here is the complete solution:
See the Pen Composition 2 by Robert Biggs (@rbiggs) on CodePen.
As you can see, with some work you can use JSX composition to advantage, even inside a class component.
Containement
Another pattern for JSX development is container, where on component contains another. In our previous example we used props to pass in a function that composed several JSX function components together. We can also pass in custom JSX tags for a similar composition pattern. Take a look at the following example. Notice how we have our custom tags defined: <Contacts />
and <Chat />
, and that we pass them to the SplitPane
tag as its value for left and right:

TypeScript API
This page gives an overview over the functionality that EZ exposes through TypeScript. For an introduction to the TypeScript language please refer to the web (for example TypeScript in 5 minutes).
Note that you don't need to install anything to use TypeScript in EZ, the required TypeScript transpiler is already included.
API Documentation
All TypeScript APIs are documented with code comments. In Visual Studio Code you can see the documentation for each function by hovering the mouse cursor over it:
You can also jump to a function or class declaration using F12
. This is useful to see what functions are available on a given class.
Importing Files (require
)
TypeScript and JavaScript have multiple mechanisms how to make code from other files available. In EZ only the require
mechanism will work:
import EZ = require("TypeScript/ez")
This imports all exported declarations from the file TypeScript/ez.ts into an object called ez in this file. Thus typing ez.
grants access to all the exported classes, namespaces and functions from that file.
The path given to require
must be relative to a data directory. For example, the file above is located in the Plugins data directory.
Note:
require
always returns an object and therefore you must assign its result to a variable. Consequently, there is no way to make the imported names globally accessible, you can only access them through that variable.
To import multiple files, you need to store each result in a different variable:
import EZ = require("TypeScript/ez")
import _ge = require("Scripting/GameEnums")
Re-exporting Imported Declarations
You can re-export declarations from a .ts
file that you imported from somewhere else. For plenty of examples, look at the file ez.ts:
import __Log = require("TypeScript/ez/Log")
export import Log = __Log.Log;
Here, everything from the file Log.ts is imported into the variable __Log
. We then selectively re-export the namespace Log
from the variable __Log
again, under the name Log
. We could rename the exported symbol, if we wanted.
Unfortunately, there does not seem to be a way to re-export all declarations automatically, you need to name each one individually.
Scenegraph
ez.Component
ez.Component
is the base class for all component types, including the C++ components. Your custom components must extend either ez.TypescriptComponent
or ez.TickedTypescriptComponent
.
The functionality exposed through ez.Component
is mostly identical to all other components.
If you hold a reference to a component for more than a frame, it is vital to use ez.Component.IsValid()
to check whether the component is still alive, before accessing it. If IsValid()
returns true, the component can be accessed safely for the rest of the frame.
ez.GameObject
ez.GameObject
exposes the game object functionality to TypeScript mostly 1:1. Through this you modify object positions, delete or move child nodes, access attached components and send messages.
You can't extend game objects.
If you hold a reference to a game object for more than a frame, it is vital to use ez.GameObject.IsValid()
to check whether it is still alive, before accessing it. If IsValid()
returns true, the game object can be accessed safely for the rest of the frame.
ez.World
ez.World
exposes the world functionality. However, the functionality provided is only a limited subset. Some functionality is simply not needed in the TypeScript binding, and some is exposed differently.
Since all TypeScript code is executed in the context of one specific world, you can't access a different world from TypeScript code. Therefore, there is no need to get the world that you operate in (as is common in C++). Therefore ez.World
is only a namespace, not a class, and all functionality is always accessible.
Additionally, functionality like ez.Clock
and ez.Random
, which are in C++ bound directly to a world, are similarly just global namespaces in TypeScript and not exposed through ez.World
.
ez.Message
ez.Message
and ez.EventMessage
are base classes for all messages. The page Messaging in TypeScript Code goes into more detail.
Math
TypeScript already provides mathematical functions through the Math
namespace. Additionally, the EZ API provides these classes:
ez.Vec2
andez.Vec3
: 2 and 3 component vectors for 2D and 3D linear algebra.ez.Mat3
andez.Mat4
: A 3x3 and 4x4 matrix.ez.Quat
: A quaternion class to handle rotations.ez.Transform
: A transform stores a position (ez.Vec3
), a rotation (ez.Quat
) and a scale factor (ez.Vec3
). It is mainly used to represent object transformations, and is more convenient than using 4x4 matrices.ez.Angle
: Provides utility functions to work with angles. Mostly to convert between radians and degree.ez.Color
: A utility class to work with colors. All colors are treated as HDR colors in linear space, though conversions to and from Gamma space are provided. See color spaces (TODO) for details.
Debugging
ez.Log
The ez.Log
namespace contains functions for writing messages to the log. This is a useful tool for debugging.
ez.Debug
The ez.Debug
namespace contains various functionality. There are functions for debug rendering, ie. to insert shapes into the rendered output, which can be helpful in visualizing many aspects. ez.Debug
also provides access to CVars and console functions.
Utilities
ez.Clock
The ez.Clock
namespace has functions to access the world's clock. The clock represents the game time, meaning it advances at its own pace, which can be adjusted dynamically. When you need to know how much time has passed since the last frame (not the last Tick()
), use ez.Clock.GetTimeDiff()
. Use ez.Clock.GetAccumulatedTime()
it you need to measure longer durations.
ez.Time
In TypeScript code time should be stored as number
types and measured in seconds. This is how all functions expect time values. ez.Time
contains utility functions to convert time values to other units and to query the current system time.
ez.Random
The ez.Random
namespace contains functions to get random numbers.
Physics
In ez.Physics
you find functions to query the physics engine. For example to do raycasts or overlap tests.

Package org.jnetpcap.winpcap Description
WinPcap extensions to libpcap avialable on a limited set of
platforms. This package adds additional functionality provided by
WinPcap library widely available on win32 based platforms. These
extensions are optional and are not available on unix based platforms.
Checking for WinPcap extension availability
Before you utilize any of the extension in this package, the programmer
must first check if the extensions are available on this particular
platform. To do that use
WinPcap.isSupported()
method which returns a boolean value. A return value of
true
means that the extensions are supported and available, while a value of
false
means they are not. All methods will throw an
PcapExtensionNotAvailableException
if used and the extensions are not supported on this particular
platform. Therefore it is essential to always perform this check before
relying on these extensions.
Main WinPcap Extension Highlights
WinPcap improves greatly on libpcap. Since WinPcap is more then
just a libbrary (its actually a set of kernel drivers as well), it kind
of holds keys to many key resources within the native platform it was
designed to run on.
Main features:
- Control of kernel buffer
- Change of capture type from normal capture to sampling
- For raw network statistics, can engage the kernel to collect
those statistics and deliver them to the application. Much more
efficient
- Samples captures. Allows capturing only a sample of the
packets instead of every single one. Several sampling modes are
available.
- Packet queues which allow the programmer to send, very
efficiently a larger set of packets. These packets are sent using raw
link layer where you have to supply even the link header, i.e.
Ethernet.
- Remote network interface and file listing. List files and
interfaces on any WinPcap capable machine running WinPcaps's rpcapd
deamon.
- Remote capture. Capture packets remotely with the same
flexibility as being local.
WinPcap Source String Syntax
WinPcap introduced a URI style syntax for addressing local and remote
resources using a single
open
call, called a
source string
. The source string is used for both
open
and
findAllDevsEx
methods. A utility method is provided to help you build a
source string
from individual components,
createSrcStr(StringBuilder, int, String, String, String,
StringBuilder)
. The method does take quiet a few parameters, but most of them are
optional and null can be supplied instead. With the utility method you
can build
source strings
based on user interactions. The result is stored in the first
StringBuilder which is essentially a char buffer.
Here is a listing of various source string formats
allowed by the open
method:
- file://path_and_filename - opens a local file
- rpcap://devicename - opens the selected device devices
available on the local host, without using the RPCAP protocol
- rpcap://host/devicename - opens the selected device available
on a remote host
- rpcap://host:port/devicename - opens the selected device
available on a remote host, using a non-standard port for RPCAP
- adaptername - to open a local adapter; kept for compability,
but it is strongly discouraged
- null - to open the first local adapter; kept for compability,
but it is strongly discouraged
The formats allowed by findAllDevsEx
method are:
- file://folder/ - lists all the files in the given folder
- rpcap:// - lists all local adapters
- rpcap://host:port/ - lists the devices available on a remote
host
And some examples:
- rpcap://host.foo.bar/devicename [everything literal, no port
number]
- rpcap://host.foo.bar:1234/devicename [everything literal, with
port number]
- rpcap://<IP_ADDRESS>/devicename [IPv4 numeric, no port number]
- rpcap://<IP_ADDRESS>:1234/devicename [IPv4 numeric, with port
number]
- rpcap://[<IP_ADDRESS>]:1234/devicename [IPv4 numeric with IPv6
format, with port number]
- rpcap://[1:2:3::4]/devicename [IPv6 numeric, no port number]
- rpcap://[1:2:3::4]:1234/devicename [IPv6 numeric, with port
number]
- rpcap://[1:2:3::4]:http/devicename [IPv6 numeric, with literal
port number]
