Frequently Asked Questions
What is the name of the cookie the login method returns that I am required to pass along on subsequent requests?
The cookie name is JSESSIONID. A sample value of JSESSIONID is EDAE73B1BB810271A430D9FA89BFF232.
I received the following soap fault. How do I avoid it?
This normally means you have an int or boolean variable on a complex type that was passed as null (e.g. xsi:nil='true'). Assuming you are using proxy objects, try initializing int variables to zero and boolean variables to false. This should prevent the variable from being null.
Fault Code: env:Client
Fault String: caught exception while handling request: deserialization error: java.lang.NullPointerException

-
Loupe Transparency
The transparency of the loupe can now be adjusted from 10% to 100%.
-
Shot Preview
A preview image has been added to the information courts.
-
Recent Shots
In the 'Screenshot' menu there is now a list of recent shots. Clicking on a recent shot will opened the shot in a browser.
-
Arrow Keys
The code for the arrow keys has been completely redone and no longer requires the 'window' menu. This rewrite also fixed a bug that cause the arrow keys to move the loupe when a text field was active instead of moving the cursor. The arrow keys have the same behavior as before, they move the loupe 1px, 10px if the ⌘ key is down.
-
Cancel Button
Now that there is a shot preview in the information court it makes sense to have a cancel button so you can take the shot again if you don't like the preview.
-
Disable Buttons
This is a minor item but the upload buttons and menu items are now disabled while a shot is being uploaded.

OOP In Ficl
Parse Steps
Release History
Upgrading To 4.0
| |
Ficl's object extensions provide the traditional OO benefits of associating
data with the code that manipulates it, and reuse through single inheritance.
Ficl also has some unusual capabilities that support interoperation with
systems written in C.
Some design points of Ficl's OOP system:
-
Ficl objects are normally late bound for safety (late binding guarantees
that the appropriate method will always be invoked for a particular object).
Early binding is also available, provided you know the object's class at
compile-time.
-
Ficl OOP supports single inheritance, aggregation, and arrays of objects.
-
Classes have independent name spaces for their methods: methods are only
visible in the context of a class or object. Methods can be overridden
or added in subclasses; there is no fixed limit on the number of methods
of a class or subclass.
-
Ficl OOP syntax is regular and unified over classes and objects. In ficl,
all classes are objects. Class methods include the ability to subclass
and instantiate.
-
Ficl can adapt legacy data structures with object wrappers. You can model
a structure in a Ficl class, and create an instance that refers to an address
in memory that holds an instance of the structure. The ref object
can then manipulate the structure directly. This lets you wrap data structures
written and instantiated in C.
If you're not familiar with object-oriented programming, you
can click here
or here for
a general-purpose overview.
Or click here for a short review of object-oriented ideas,
terms, and implementations in C.
Ficl is not the first Forth to include Object Oriented extensions. Ficl's
OO syntax owes a debt to the work of John Hayes and Dick Pountain, among
others. OO Ficl is different from other OO Forths in a few ways, though
(some things never change). First, unlike several implementations, the
syntax is documented (below) beyond the source
code. In Ficl's spirit of working with C code, the OO syntax provides means
to adapt existing data structures. I've tried to make Ficl's OO model simple
and safe by unifying classes and objects, providing late binding by default,
and separating namespaces so that methods and regular Forth words are not
easily confused.
All classes in Ficl are derived from the common base class
OBJECT
as shown in the figure below. All classes are instances
of METACLASS . This means that classes
are objects, too. METACLASS implements the methods for messages
sent to classes. Class methods create instances and subclasses, and give
information about the class. Each class is represented by a data stucture
of three elements:
-
The address (named
.CLASS ) of a parent class, or zero if it's
a base class (only OBJECT and METACLASS have this property).
-
The size (named
.SIZE ) in address units of an instance of the
class.
-
A wordlist ID (named
.WID ) for the methods of the class.
In the figure below, METACLASS and OBJECT are real system-supplied
classes. The others are contrived to illustrate the relationships among
derived classes, instances, and the two system base classes. The dashed
line with an arrow at the end indicates that the object/class at the arrow
end is an instance of the class at the other end. The vertical line with
a triangle denotes inheritance.
Note for the curious: METACLASS behaves like a class—it responds
to class messages and has the same properties as any other class. If you
want to twist your brain in knots, you can think of METACLASS
as an instance of itself.
It's helpful to have some familiarity with Forth and the customary Forth
stack notation to understand this tutorial. To get started, take a look
at this web-based
Forth tutorial. If you're comfortable with both OO and Forth, you can
jump ahead.
A Ficl object associates a class
with an instance (the storage for
one set of instance variables). This is done explicitly on Ficl's stack,
in that any Ficl object is represented by a cell pair:
( INSTANCE-address CLASS-address )
The INSTANCE-address is the address of the object's storage, and the CLASS-address
is the address of its class. Whenever a named Ficl object executes (e.g.
when you type its name and press enter at the Ficl prompt), it leaves this
"signature". All methods by convention expect a class and instance on the
stack when they execute, too. In many other OO languages, including C++,
instances contain information about their classes (a vtable
pointer, for example). By making this pairing explicit rather than implicit,
Ficl can be OO about chunks of data that don't realize that they are objects,
without sacrificing any robustness for native objects. That means that
you can use Ficl to write object wrappers for data structures created in
C or assembly language, as long as you can determine how they're laid out
in memory.
Whenever you create an object in Ficl, you specify its class.
After that, the object always pushes its class and the address of its
payload
(instance variable space) when invoked by name.
Classes are special kinds of objects that store the methods of their
instances, the size of an instance's payload, and a parent class pointer.
Classes themselves are instances of a special base class called METACLASS ,
and all classes inherit from class OBJECT . This is confusing at
first, but it means that Ficl has a very simple syntax for constructing
and using objects. Class methods include subclassing (SUB ), creating
initialized and uninitialized instances (NEW and INSTANCE ),
and creating reference instances (REF ), described later. Classes
also have methods for disassembling their methods (SEE ), identifying
themselves (ID ), and listing their pedigree (PEDIGREE ).
All objects inherit (from OBJECT ) methods for initializing instances
and arrays of instances, for performing array operations, and for getting
information about themselves.
Methods are the functions that objects execute in response to messages.
A message is a request to an object for a behavior that the object supports.
When it receives a message, the target object looks up a method that performs
the behavior for its class, and executes it. Any specific message may be
bound to different methods in different objects, according to class. This
separation of messages and methods allows objects to behave polymorphically.
(In Ficl, methods are words defined in the context of a class, and messages
are the names of those words.) Ficl classes associate messages with methods
for their instances (a fancy way of saying that each class owns a wordlist).
Ficl provides a late-binding operator --> that sends messages
to objects at run-time, and an early-binding operator =>
that compiles a specific class's method. These operators are the only supported
way to invoke methods. Regular Forth words are not visible to the method-binding
operators, so there's no chance of confusing a message with a regular
word of the same name.
(Finally!)
This is a tutorial. It works best if you follow along by pasting the examples
into ficlWin, the Win32 version of Ficl included with the release sources
(or some other build that includes the OO part of softcore.c ). If you're
not familiar with Forth, please see one of these references.
Ficl's OOP words are in vocabulary OOP . To put OOP in
the search order and make it the compilation wordlist, type:
ONLY
ALSO OOP DEFINITIONS
Note for beginners: To see the effect of the commands above, type
ORDER
after each line. You can repeat the sequence above if you like.
To start, we'll work with the two base classes OBJECT and METACLASS .
Try this:
METACLASS --> METHODS
The line above contains three words. The first is the name of a class,
so it pushes its signature on the stack. Since all classes are instances
of METACLASS , METACLASS behaves as if it is an instance
of itself (this is the only class with this property). It pushes the same
address twice: once for the class and once for the payload, since they
are the same. The next word finds a method in the context of a class and
executes it. In this case, the name of the method is METHODS .
Its job is to list all the methods that a class knows. What you get when
you execute this line is a list of all the class methods Ficl provides.
OBJECT --> SUB C-LED
Causes the base-class OBJECT to derive from itself a new class
called C-LED . Now we'll add some instance variables and methods to the new class.
Note: I like to prefix the names of classes with c- and the
names of member variables with a period, but this is just a convention.
If you don't like it, pick your own.
C-BYTE OBJ: .STATE
: INIT { 2:THIS -- }
THIS --> SUPER --> INIT
."  This particular instance variable is an object—it will be an instance
of C-BYTE , one of Ficl's stock classes (the source for which can be found
in the distribution in softcore/classes.fr ).
Next we've defined a method called INIT . This line also declares
a local variable called THIS
(the 2 in front tells Ficl that this is a double-cell local). All methods
by convention expect the address of the class and instance on top of the
stack when called. The next three lines define the behavior of INIT when it's called.
It first calls its superclass's version of INIT (which in this
case is "OBJECT => INIT "—this default implementation clears all
instance variables). The rest displays some text and causes the instance
to print its class name (THIS --> CLASS --> ID ).
The INIT > method is special for Ficl objects: whenever
you create an initialized instance using NEW or NEW-ARRAY ,
Ficl calls the class's INIT method for you on that instance. The
default INIT method supplied by OBJECT clears the instance,
so we didn't really need to override it in this case (see the source code
in softcore/oo.fr ).
The ON and OFF methods defined above hide the details
of turning LEDs on and off. The interface to FiclWin's simulated hardware
is handled by !OREG . The class keeps the LED state in a shadow
variable (.STATE ) so that ON and OFF can work
in terms of LED number rather than a bitmask.
Now make an instance of the new class:
C-LED --> NEW LED
And try a few things...
LED --> METHODS
LED --> PEDIGREE
1 LED --> ON
1 LED --> OFF
Or you could type this with the same effect:
LED 2DUP --> METHODS --> PEDIGREE
Notice (from the output of METHODS ) that we've overridden the
INIT method supplied by object, and added two more methods for the member
variables. If you type WORDS , you'll see that these methods are
not visible outside the context of the class that contains them. The method
finder --> uses the class to look up methods. You can use
this word in a definition, as we did in INIT , and it performs
late binding, meaning that the mapping from message (method name) to method
(the code) is deferred until run-time. To see this, you can decompile the
init method like this:
C-LED --> SEE INIT
or
LED --> CLASS --> SEE INIT
Ficl also provides early binding if you ask for it. Early binding is not
as safe as late binding, but it produces code that is more compact and
efficient because it compiles method addresses rather then their names.
In the preferred uses of early binding, the class is assumed to be the
one you're defining. This kind of early binding can only be used inside
a class definition. Early bound methods still expect to find a class and
instance cell-pair on top of the stack when they run.
Here's an example that illustrates a potential problem:
OBJECT --> SUB C1
: M1 { 2:THIS -- } ." C1'S M1" CR ;
: M2 { 2:THIS -- } ." Running " THIS MY=> M1 ; ( early )
: M3 { 2:THIS -- } ." Running " THIS --> M1 ( late )
END-CLASS
C1 --> SUB C2
: M1 { 2:THIS -- } ." C2'S M1" CR ;
END-CLASS
C2 --> NEW I2
I2 --> M1 ( runs the M1 defined in C2 )
I2 --> M2 ( Is this what you wanted? )
I2 --> M3 { runs the overridden M1)
Even though we overrode method M1 in class C2 , the definition of M2 with
early binding forced the use of M1 as defined in C1 . If that's what you
want, great, but more often you'll want the flexibility of overriding parent
class behaviors appropriately.
-
MY=> binds early to a method in the class being defined,
as in the example above.
-
MY=[ ] binds a sequence of methods in the current class.
Useful when the class has object members. Lines like
THIS --> STATE --> SET in the definition of C-LED above can be replaced with
THIS MY=[ STATE SET ] to use early binding.
-
=> (dangerous) pops a class off the stack and compiles
the method in that class. Since you have to specify the class explicitly,
there is a real danger that this will be out of sync with the class you
really wanted. I recommend you use MY=> or MY=[ ] instead.
Early binding using => is dangerous because it partially
defeats the data-to-code matching mechanism object oriented languages were
created to provide, but it does increase run-time speed by binding the
method at compile time. In many cases, such as the INIT method,
you can be reasonably certain of the class of thing you're working on.
This is also true when invoking class methods, since all classes are instances
of METACLASS . Here's an example from the definition of METACLASS
in oo.fr (don't paste this into ficlWin—it's already there):
: NEW \ ( class metaclass "name" -- )
METACLASS => INSTANCE --> INIT ;
Try this:
METACLASS --> SEE NEW
Decompiling the method with SEE shows the difference between the
two strategies. The early bound method is compiled inline, while the late-binding
operator compiles the method name and code to find and execute it in the
context of whatever class is supplied on the stack at run-time.
Notice that the primitive early-binding operator => requires
a class at compile time. For this reason, classes are IMMEDIATE ,
meaning that they push their signature at compile time or run time. I'd
recommend that you avoid early binding until you're very comfortable with
Forth, object-oriented programming, and Ficl's OOP syntax.
Untyped instance variable methods (created by CELL: CELLS: CHAR:
and CHARS: ) just push the address of the corresponding instance
variable when invoked on an instance of the class. It's up to you to remember
the size of the instance variable and manipulate it with the usual Forth
words for fetching and storing.
As advertised earlier, Ficl provides ways to objectify existing data
structures without changing them. Instead, you can create a Ficl class
that models the structure, and instantiate a ref from this class,
supplying the address of the structure. After that, the ref instance
behaves as a Ficl object, but its instance variables take on the values
in the existing structure. Example (from softcore/ficlclass.fr ):
OBJECT SUBCLASS C-WORDLIST
C-WORDLIST REF: .PARENT
C-PTR OBJ: .NAME
C-CELL OBJ: .SIZE
C-WORD REF: .HASH ( first entry in hash table )
: ?
--> GET-NAME ." ficl wordlist " TYPE CR ;
: PUSH DROP >SEARCH ;
: POP 2DROP PREVIOUS ;
: SET-CURRENT DROP SET-CURRENT ;
: GET-NAME DROP WID-GET-NAME ;
: WORDS { 2:THIS -- }
THIS MY=[ .SIZE GET ] 0 DO
I THIS MY=[ .HASH INDEX ] ( 2list-head )
BEGIN
2DUP --> GET-NAME TYPE SPACE
--> NEXT OVER
0= UNTIL 2DROP CR
LOOP
;
END-CLASS
In this case, C-WORDLIST describes Ficl's wordlist structure;
NAMED-WID creates a wordlist and binds it to a ref instance of
C-WORDLIST .
The fancy footwork with POSTPONE and early binding is required
because classes are immediate. An equivalent way to define NAMED-WID with
late binding is:
: NAMED-WID ( c-address u -- )
WORDLIST POSTPONE C-WORDLIST --> REF
;
To do the same thing at run-time (and call it MY-WORDLIST ):
wordlist c-wordlist --> ref my-wordlist
Now you can deal with the wordlist through the ref instance:
MY-WORDLIST --> PUSH
MY-WORDLIST --> SET-CURRENT
ORDER
Ficl can also model linked lists and other structures that contain pointers
to structures of the same or different types. The class constructor word
REF:
makes an aggregate reference to a particular class. See the instance
variable glossary for an example.
Ficl can make arrays of instances, and aggregate arrays into class descripions.
The class methods ARRAY and NEW-ARRAY
create uninitialized and initialized arrays, respectively, of a class.
In order to initialize an array, the class must define (or inherit) a reasonable
INIT method. NEW-ARRAY invokes it on each member of the array
in sequence from lowest to highest. Array instances and array members use
the object methods INDEX , NEXT , and PREV
to navigate. Aggregate a member array of objects using ARRAY: .
The objects are not automatically initialized in this case—your class
initializer has to call ARRAY-INIT explicitly if you want
this behavior.
For further examples of OOP in Ficl, please see the source file softcore/ficlclass.fr .
This file wraps several Ficl internal data structures in objects and gives
use examples.
C-STRING is a reasonably useful dynamic string class.
Source code for the class is located in softcore/string.fr .
Features:
dynamic creation and resizing; deletion, char cout, concatenation, output,
comparison; creation from quoted string constant (S" ).
Examples of use:
C-STRING --> NEW HOMER
S" In this house, " HOMER --> SET
S" we obey the laws of thermodynamics!" HOMER --> CAT
HOMER --> TYPE
Note: With the exception of the binding operators (the first two definitions
here), all of the words in this section are internal factors that you don't
need to worry about. These words provide method binding for all classes
and instances. Also described are supporting words and execution factors.
All are defined in softcore/oo.fr .
--> ( instance class "method-name" -- xn ) -
Late binding: looks up and executes the given method in the context of
the class on top of the stack.
C-> ( instance class "method-name" -- xn exc ) -
Late binding with
CATCH : looks up and CATCH es the given
method in the context of the class on top of the stack, pushes zero or
exception code upon return.
MY=> compilation: ( "method-name" -- ) execution: ( instance class -- xn ) -
Early binding: compiles code to execute the method of the class being defined.
Only visible and valid in the scope of a
--> SUB .. END-CLASS
class definition.
MY=[ compilation: ( "obj1 obj2 .. method ]" -- ) execution: ( instance class -- xn ) -
Early binding: compiles code to execute a chain of methods of the class
being defined. Only visible and valid in the scope of a
--> SUB
.. END-CLASS class definition.
=> compilation: ( class metaclass "method-name" -- ) execution: ( instance class -- xn ) -
Early binding: compiles code to execute the method of the class specified
at compile time.
do-do-instance -
When executed, causes the instance to push its
( INSTANCE CLASS ) stack
signature. Implementation factor of METACLASS --> SUB .
Compiles .DO-INSTANCE in the context of a class; .DO-INSTANCE
implements the DOES> part of a named instance.
exec-method ( instance class c-address u -- xn ) -
Given the address and length of a method name on the stack, finds
the method in the context of the specified class and invokes it. Upon entry
to the method, the instance and class are on top of the stack, as usual.
If unable to find the method, prints an error message and aborts.
find-method-xt ( class "method-name" -- class xt ) -
Attempts to map the message to a method in the specified class. If successful,
leaves the class and the execution token of the method on the stack. Otherwise
prints an error message and aborts.
lookup-method ( class c-address u -- class xt ) -
Given the address and length of a method name on the stack, finds
the method in the context of the specified class. If unable to find the
method, prints an error message and aborts.
parse-method compilation: ( "method-name" -- ) execution: ( -- c-address u ) -
Parse
"method-name" from the input stream and compile code to push its length
and address when the enclosing definition runs.
Note:: These words are only visible when creating a subclass! To
create a subclass, use the SUB method on OBJECT or any
class derived from it (not METACLASS ). Source code for
Ficl OOP is in softcore/oo.fr .
Instance variable words do two things: they create methods that do
san action appropriate for the type of instance variable they represent,
and they reserve space in the class template for the instance variable.
We'll use the term instance variable to refer both to the method
that gives access to a particular field of an object, and to the field
itself. Rather than give esentially the same example over and over, here's
one example that shows several of the instance variable construction words
in use:
OBJECT SUBCLASS C-EXAMPLE
CELL: .CELL0
C-4BYTE OBJ: .NCELLS
4 C-4BYTE ARRAY: .QUAD
CHAR: .LENGTH
79 CHARS: .NAME
END-CLASS
This class only defines instance variables, and it inherits some methods
from OBJECT . Each untyped instance variable (.CELL0 , .LENGTH ,
.NAME ) pushes its address when executed. Each object instance variable
pushes the address and class of the aggregate object. Similar to C, an
array instance variable leaves its base address (and its class) when executed.
The word SUBCLASS is shorthand for --> sub .
CELL: compilation: ( offset "name" -- offset ) execution: ( -- cell-address ) -
Create an untyped instance variable one cell wide. The instance variable
leaves its payload's address when executed.
CELLS: compilation: ( offset nCells "name" -- offset' ) execution: ( -- cell-address ) -
Create an untyped instance variable
nCells cells wide.
CHAR: compilation: ( offset "name" -- offset' ) execution: ( -- cell-address ) -
Create an untyped member variable one character wide.
CHARS: compilation: ( offset nChars "name" -- offset' ) execution: ( -- cell-address ) -
Create an untyped member variable
nChars characters wide.
OBJ: compilation: ( offset class metaclass "name" -- offset' ) execution: ( -- instance class ) -
Aggregate an uninitialized instance of
CLASS as a member variable
of the class under construction.
ARRAY: compilation: ( offset nObjects class metaclass "name" -- offset' ) execution: ( -- instance class ) -
Aggregate an uninitialized array of instances of the class specified as
a member variable of the class under construction.
EXAMPLEREF: compilation: ( offset class metaclass "name" -- offset' ) execution: ( -- ref-instance ref-class ) -
Aggregate a reference to a class instance. There is no way to set the value
of an aggregated ref—it's meant as a way to manipulate existing data
structures with a Ficl OO model. For example, if your system contains a
linked list of 4 byte quantities, you can make a class that represents
a list element like this:
OBJECT SUBCLASS C-4LIST
C-4LIST REF: .LINK
C-4BYTE OBJ: .PAYLOAD
END-CLASS
ADDRESS-OF-EXISTING-LIST C-4LIST --> REF MYLIST
-
The last line binds the existing structure to an instance of the class
we just created. The link method pushes the link value and the class
C_4LIST ,
so that the link looks like an object to Ficl and like a struct to C (it
doesn't carry any extra baggage for the object model—the Ficl methods
alone take care of storing the class information).
Note: Since a REF: aggregate can only support one class, it's good for
modeling static structures, but not appropriate for polymorphism. If you
want polymorphism, aggregate a C_REF (see softcore/classes.fr for source)
into your class—it has methods to set and get an object.
By the way, it is also possible to construct a pair of classes that contain
aggregate pointers to each other. Here's an example:
OBJECT SUBCLASS AKBAR
SUSPEND-CLASS \ put akbar on hold while we define jeff
OBJECT SUBCLASS JEFF
AKBAR REF: .SIGNIFICANT-OTHER
( ... your additional methods here ... )
END-CLASS \ done with jeff
AKBAR --> RESUME-CLASS \ resume defining akbar
JEFF REF: .SIGNIFICANT-OTHER
( ... your additional methods here ... )
END-CLASS \ done with akbar
These words are methods of METACLASS . They define the manipulations
that can be performed on classes. Methods include various kinds of instantiation,
programming tools, and access to member variables of classes. Source is
in softcore/oo.fr .
INSTANCE ( class metaclass "name" -- instance class ) -
Create an uninitialized instance of the class, giving it the name specified.
The method leaves the instance's signature on the stack (handy if you
want to initialize). Example:
C_REF --> INSTANCE UNINIT-REF 2DROP
NEW ( class metaclass "name" -- ) -
Create an initialized instance of class, giving it the name specified.
This method calls
INIT to perform initialization.
ARRAY ( nObjects class metaclass "name" -- nObjects instance class ) -
Create an array of
nObjects instances of the specified class.
Instances are not initialized. Example:
10 C_4BYTE --> ARRAY 40-RAW-BYTES 2DROP DROP
NEW-ARRAY ( nObjects class metaclass "name" -- ) -
Creates an initialized array of
nObjects instances of the class.
Same syntax as ARRAY .
ALLOC ( class metaclass -- instance class ) -
Creates an anonymous instance of
CLASS from the heap (using a call
to ficlMalloc() to get the memory). Leaves the payload and class addresses
on the stack. Usage example:
C-REF --> ALLOC 2CONSTANT INSTANCE-OF-REF
Creates a double-cell constant that pushes the payload and class address
of a heap instance of C-REF .
ALLOC-ARRAY ( nObjects class metaclass -- instance class ) -
Same as
NEW-ARRAY , but creates anonymous instances from the heap using
a call to ficlMalloc() . Each instance is initialized using the class's
INIT method.
ALLOT ( class metaclass -- instance class ) -
Creates an anonymous instance of
CLASS from the dictionary. Leaves
the payload and class addresses on the stack. Usage example:
C-REF --> ALLOT 2CONSTANT INSTANCE-OF-REF
Creates a double-cell constant that pushes the payload and class address
of a heap instance of C-REF .
ALLOT-ARRAY ( nObjects class metaclass -- instance class ) -
Same as
NEW-ARRAY , but creates anonymous instances from the dictionary.
Each instance is initialized using the class's INIT method.
REF ( instance-address class metaclass "name" -- ) -
Make a ref instance of the class that points to the supplied instance address.
No new instance space is allotted. Instead, the instance refers to the
address supplied on the stack forever afterward. For wrapping existing
structures.
SUB ( class metaclass -- old-wid address[size] size ) -
Derive a subclass. You can add or override methods, and add instance variables.
Alias:
SUBCLASS . Examples:
C_4BYTE --> SUB C_SPECIAL4BYTE
( ... your new methods and instance variables here ... )
END-CLASS
or
C_4BYTE SUBCLASS C_SPECIAL4BYTE
( ... your new methods and instance variables here ... )
END-CLASS
.SIZE ( class metaclass -- instance-size ) -
Returns address of the class's instance size field, in address units. This
is a metaclass member variable.
.SUPER ( class metaclass -- superclass ) -
Returns address of the class's superclass field. This is a metaclass member
variable.
.WID ( class metaclass -- wid ) -
Returns the address of the class's wordlist ID field. This is a metaclass
member variable.
GET-SIZE ( -- instance-size ) -
Returns the size of an instance of the class in address units. Imeplemented
as follows:
: GET-SIZE METACLASS => .SIZE @ ;
GET-WID ( -- wid ) -
Returns the wordlist ID of the class. Implemented as:
: GET-WID METACLASS => .WID @ ;
GET-SUPER ( -- superclass ) -
Returns the class's superclass. Implemented as
: GET-SUPER METACLASS => .super @ ;
ID ( class metaclass -- c-address u ) -
Returns the address and length of a string that names the class.
METHODS ( class metaclass -- ) -
Lists methods of the class and all its superclasses.
OFFSET-OF ( class metaclass "name" -- offset ) -
Pushes the offset from the instance base address of the named member variable.
If the name is not that of an instance variable method, you get garbage.
There is presently no way to detect this error. Example:
metaclass --> offset-of .wid
PEDIGREE ( class metaclass -- ) -
Lists the pedigree of the class (inheritance trail).
SEE ( class metaclass "name" -- ) -
Decompiles the specified method—obect version of
SEE , from the
TOOLS wordset.
These are methods that are defined for all instances by the base class
OBJECT .
The methods include default initialization, array manipulations, aliases
of class methods, upcasting, and programming tools.
INIT ( instance class -- ) -
Default initializer, called automatically for all instances created with
NEW
or NEW-ARRAY . Zero-fills the instance. You do not normally need
to invoke INIT explicitly.
ARRAYINIT ( nObjects instance class -- ) -
Applies
INIT to an array of objects created by NEW-ARRAY .
Note that ARRAY: does not cause aggregate arrays to be initialized
automatically. You do not normally need to invoke ARRAY-INIT explicitly.
FREE ( instance class -- ) -
Releases memory used by an instance previously created with
ALLOC
or ALLOC-ARRAY . Note: This method is not presently protected
against accidentally deleting something from the dictionary. If you do
this, Bad Things are likely to happen. Be careful for the moment to apply
free only to instances created with ALLOC or ALLOC-ARRAY .
CLASS ( instance class -- class metaclass ) -
Convert an object signature into that of its class. Useful for calling
class methods that have no object aliases.
SUPER ( instance class -- instance superclass ) -
Upcast an object to its parent class. The parent class of
OBJECT
is zero. Useful for invoking an overridden parent class method.
PEDIGREE ( instance class -- ) -
Display an object's pedigree—its chain of inheritance. This is an alias
for the corresponding class method.
SIZE ( instance class -- instance-size ) -
Returns the size, in address units, of one instance. Does not know about
arrays! This is an alias for the class method
GET-SIZE .
METHODS ( instance class -- ) -
Class method alias. Displays the list of methods of the class and all superclasses
of the instance.
INDEX ( n instance class -- instance[n] class ) -
Convert array-of-objects base signature into signature for array element
n. No check for bounds overflow. Index is zero-based, like C, so
0 MY-OBJ --> INDEX
is equivalent to
MY-OBJ
Check out the description of -ROT for
help in dealing with indices on the stack.
NEXT ( instance[n] class -- instance[n+1] ) -
Convert an array-object signature into the signature of the next
object in the array. No check for bounds overflow.
PREV ( instance[n] class -- instance[n-1] class ) -
Convert an object signature into the signature of the previous object
in the array. No check for bounds underflow.
For more information on theses classes, see softcore/classes.fr .
METACLASS -
Describes all classes of Ficl. Contains class methods. Should never be
directly instantiated or subclassed. Defined in
softcore/oo.fr . Methods described
above.
OBJECT -
Mother of all Ficl objects. Defines default initialization and array indexing
methods. Defined in
softcore/oo.fr . Methods described above.

public class ConnectionManager
extends java.lang.Object
implements java.lang.Runnable
We need to be careful about concurrency here--things are happening async and we can be multithreaded. This is a singleton.
This is also multi-threaded. It turns out that when a packet is received from a client, it's a bad idea to repeat that packet out to all connections in the same thread. It takes a long time, and the WebPageConnection object can't receive more packets while the data is being distributed out to all the other connections (which, remember, takes a long time.) Instead, as soon as an incoming message is received from a client, it's placed into a FIFO queue (with concurrency protection) in this class. The logic in the onBinaryMessage can immediately return, and the logic in this thread can retrieve the message from the queue and distribute it to the other participants. Since almost everything, even phones, have multi-core CPUs these days this can happen in parallel.
The method that retrieves the next message from the queue will block if there are no messages in the queue.

A BUG'S LIFE
*** 1/2 (out of 4) - a great movie
Release Date: November 25, 1998 The Voices of: Dave Foley, Kevin Spacey, Julia Louis-Dreyfus, Hayden Panettiere, Phyllis Diller, Denis Leary, Joe Ranft, John Ratzenberger Directed by: John Lasseter, Andrew Stanton Distributed by: Buena Vista Pictures MPAA Rating: G URL: http://www.execpc.com/~kinnopio/reviews/1998/bugslife.htm
Lest their be any question of whether or not the Mouse House still packs any animated clout, consider this to be the convincing argument otherwise.
With a eerie feeling of déjà vu and a virtual replay of events earlier this year, Disney's computer-animated movie about insects, A BUG'S LIFE, not only beat out the competition (DreamWorks' ANTZ), but did so by a good measure. Although there may have been doubt as to which of the "double-vision" asteroid pics would succeed (DreamWorks' DEEP IMPACT versus Disney's ARMAGEDDON), there was no question when DreamWorks chose to challenge Disney on its own turf. The animation in A BUG'S LIFE is of the finest quality, superb in design and free of the flaws that plagued DreamWorks' picture. The graphic end of the movie -- a bright palette of pastel hues -- runs smoothly and to great effect.
Unlike ANTZ, which was a story of internal strife in an ant colony, A BUG'S LIFE returns to Æsopian ground and gives us a tale of ants against grasshoppers. Strictly speaking, both the script and the voice talent in A BUG'S LIFE is not nearly as developed as that of ANTZ (the latter being written with more thought and intelligence), but the simplicity of A BUG'S LIFE is the key to its success. The movie is a departure from the serious fare of the competition's animation studios, and, in true Disney fashion, is plea to the viewer's inner child. Characters are drawn with an attitude of innocence, and bad guys are sulking, sneering characters. It's the typical Disney formula, and as far as many are concerned, that formula's still tops.
The story centers around the life of an ant named Flik (Dave Foley, TV's "News Radio"), whose curious tendancies land his colony in trouble when he unknowingly ruins the year's harvest. Flik's colony gathers food for a gang of grasshoppers, but when Flik sends the offering into the drink, the lead grasshopper, Hopper (Kevin Spacey), delivers an ultimatum. The ants must gather a replacement harvest by autumn, or Hopper and his gang will destroy the colony. Flik decides to make amends by gathering a group of warrior bugs to fight the grasshoppers, and to keep him out of the way, the colony's Princess Atta (Julia Louis-Dreyfus, TV's "Seinfeld") gives him approval. So Flik heads to the "city" and returns with a troupe of circus bugs whom he believes to be great warriors, just in time for he first day of autumn.
The script is peppered with witticisms to keep the older crowd interested, and there's plenty of slapstick comedy for the younger ones. At an hour and forty minutes, however, the movie runs a bit longer than necessary; kids may grow restless nearing the end. Fortunately, the competition over the holiday weekend isn't much better: BABE: PIG IN THE CITY and THE RUGRATS MOVIE are both over ninety minutes in length. For family entertainment, it doesn't get much better than this, and the Academy may just think so as well -- there's something here for everyone.

// Problem: If I enter 10, it gives me the CASE 1 answer. If I enter 44, it gives me the CASE 4 answer instead of DEFAULT. I also get a warning on CASE 10 for "multi characters".
(From "Starting Out C++..." by Tony Gaddis 8ed. Chapter 4, problem 2)
a Char variable can only accept one character value. so when you enter "10" it's not going to accept the 0 and will only accept the "1" which is why when you enter "44" it just grabbed the first "4" and threw away the other "4".

Mutations in the proteolipid protein gene in Japanese families with Pelizaeus-Merzbacher disease.
Abstract
Pelizaeus-Merzbacher disease (PMD) is a rare X-linked dysmyelinating disorder of the CNS resulting from abnormalities in the proteolipid protein (PLP) gene. Exonic mutations in the PLP gene are present in 10 to 25% of all cases. In investigating genotype-phenotype correlations, we screened five Japanese families with PMD for PLP gene mutations and compared their clinical manifestations. We identified two novel nucleotide substitutions in exon 5, at V208N and at P210L, in two families. In the remaining three families, there were no mutations detected. Although all patients satisfied the criteria for the classical form of PMD, two families not carrying the mutations showed milder clinical manifestations than those with the mutations. Since linkage analysis has shown homogeneity at the PLP locus in patients with PMD, our findings suggest that there may be genetic abnormalities other than exonic mutations that cause milder forms of PMD.


Asynchronous usageedit
All of the methods across the different clients exist in a traditional synchronous and asynchronous variant. The difference is that the asynchronous ones use asynchronous requests in the REST Low Level Client. This is useful if you are doing multiple requests or are using e.g. rx java, Kotlin co-routines, or similar frameworks.
The asynchronous methods are recognizable by the fact that they have the word "Async" in their name
and return a Cancellable
instance. The asynchronous methods accept the same request object
as the synchronous variant and accept a generic ActionListener<T>
where T
is the return
type of the synchronous method.
All asynchronous methods return a Cancellable
object with a cancel
method that you may call
in case you want to abort the request. Cancelling
no longer needed requests is a good way to avoid putting unnecessary
load on Elasticsearch.
Using the Cancellable
instance is optional and you can safely ignore this if you have
no need for this. A use case for this would be using this with e.g. Kotlin’s suspendCancellableCoRoutine
.


Titanic Quarter distribution centre plan set to go ahead
A PLAN for a major new distribution centre in Belfast's Titanic Quarter can go ahead, city planning officials have signalled.
Titanic Quarter Ltd's proposal would see the demolition of the existing industrial building on the site next to Queens Road, replacing it with a modern and larger 100,000 sq ft facility.
Industry monitor Construction Information Services estimates the value of the project at just under £6 million.
Most of the new development (86,100 sq ft) will be dedicated to the new distribution warehouse, with another 7,000 sq ft set aside for a van storage centre.
In a report prepared for Belfast City Council's planning committee monthly meeting on Tuesday, 560 parking spaces will be provided on site. A total of 318 spaces will be specifically for delivery vans, with 161 set aside for drivers. Another 81 are earmarked for staff and visitors.
That report recommends approval for the project.
Titanic Quarter Ltd is a company set up to develop 161.5 acres within the Titanic Quarter ultimately owned by landlord Belfast Harbour Commissioners.
It is one of a group of companies that makes up Titanic Property Development Ltd.
The group has overseen around £425m of development projects to date, comprising around 1.5 million square feet. Its directors have valued the development land at £25.9m.
The latest major development includes Olympic House on Queens Road. Enabling works on the £26.5m office building began in June.
The most recent accounts for Titanic Property Development Ltd show it turned a pre-tax profit of £4.9m in the 12 months to December 31 2018, down on a pre-tax profit of £6.2m from 2017.
Titanic Property Development Ltd's ultimate controlling parties are the Entice Limited Partnership, owned by Irish businessman Dermot Desmond and Dockside Investments, which is owned by the family of Irish property developer Pat Doherty.
The report states that both parent parties have confirmed they will not seek repayment of £26.3m of existing loans for the foreseeable future.
Shareholder loans are subordinated to Danske Bank and Bottin Investments, which is also owned by Dermot Desmond. In 2017, Mr Desmond injected an additional £29m into the company.
The Titanic group of companies also refinanced £75m worth of loans with Danske bank the same year.

Because of the secretive nature of this project, I signed a non-disclosure agreement. As such, all images and information on this page is taken from press releases and articles approved by Nissan.
I spent the summers of 2014 and 2015 at the Nissan Research Center in Sunnyvale, California. I worked on a team of software developers and roboticists working on creating an autonomous vehicle prototyping platform.
My work focused on the installation and integration of sensors as some work on the fusing of data we received from them. Unfortunately, I cannot go into detail about what I was working on. I learned a lot over my two summers there, especially about software development as a team. While at Nissan, I learned how to use Git, Agile Development and Scrum. I also learned a lot about the importance of readable code and documentation.


Project Description
T4SQL is a SQL Code Generation implemented by
Preprocessed T4 Text Templates (C# or Visual Basic).
Two initiative scenarios of using T4SQL:
- When designing a knowledge-based data analysis tool, the T4SQL can act as a generic method base subsystem which manages SQL-level objects with programmability in database (SQL Server or Oracle);
- When building a database application, if you prefer to separate particular data transformation logics from the business framework logics, to have a cleaner code. The T4SQL can act as a method-factory, designed for database developers to use generic SQL
script library as easy as OOP Generic Class Library.
In Branches-Leaves (Tree) pattern database development, to make a distinction between
the context flowchart (Branches) and the particular data transformation (Leaves):
- Business context logics look like a deciduous tree in winter. A clear highlighted Branches graphic would help our mind to control complexity all the time.
- A generic encapsulated Leaves picture would help our mind to liberate ourselves from the repeat of similar labor as much as possible. The T4SQL can be used as a Leaves Factory.
Driven by minimized configured parameters and metadata in the practical environment, every generated object is early binding rather than dynamic SQL. This allows database engine optimizer to prepare execution plans in advance and makes unit testing clearer
and easier.
A built-in Generic View Library is shipped with the release, also as a sample to make your own generic SQL libraries.
Project Organization
T4SQL mainly consists of three modules:
T4SQL Workspaces, Template Engine and
Template Library.
T4SQL Workspaces
Each workspace is a set of workitems in database, includes a
WORKITEM table and a
PROPERTY table. Database developers usually work on database directly, some team doesn't want their stuff be seen by other teams. It's necessary to create a autonomous workspace for them.
A workitem is a single database object (e.g. a View) which needs to be created or maintained.
Above TEMPLATE_NAME is the fully qualified name (including the namespace) of .NET class in Template Library. It is a crucial key for Template Engine to dispatch the specified Template to generate the object code. The
TEMPLATE_NAME column is a foreign key tie to a global table
T4SQL.TEMPLATE_CLASS which is maintained by Template Engine automatically (see also detail in upcoming Template Engine Section).
The START_BUILD is the control switch which tells Template Engine to turn on the code generation process for that workitem. After a request is completed, the engine will save the generated code into OBJECT_CODE column (if successful) or save the error message
into COMPILED_ERROR column (if failed), and reset the START_BUILD to be off.
For each workitem there should be a series of working properties as parameters for engine to invoke a template. When a new workitem is added into the
WORKITEM table, a trigger behind it will pre-copy all designed properties into below
PROPERTY table with either
ExampleValue (must be customized) or DefaultValue (can leave it as it is), you only need to update them as your particular requirement environment.
Above STRING_VALUE is the column which you need to update. It is template's responsibility to parse the text.
The LINK_STATE column is reserved for some case to pass the object state.
In practice, it's recommended to use a writeable view (just the same name as the
PROPERTY table with a "VW_" prefix) since the view can give you reference information at a glance during editing above STRING_VALUE and LINK_STATE columns, such as property description, custom is a must or not, etc.
A utility stored procedure T4SQL.META_
CREATE_WORKSPACE(…) is used for creating a new workspace, it will create a pair of
WORKITEM table and
PROPERTY table, including all necessary constraints (FK, PK…), triggers and a helper view for you.
T4SQL.CMD_
BUILD_SCRIPTS(…) is a handy stored procedure to generate all objects which match the search criteria into a single script and prints on Message Screen.
Template Engine
T4SQL Template Engine is a Windows Service which acts as the dispatch center.
Please deploy installation scripts onto database side
and run setup.exe to install T4SQL Template Engine Service in Windows server side.
Make sure to modify the connectionStrings in T4SQL.EngineService.exe.config before start up the service.
- Different config for SQL Server
<connectionStrings>
<add
name="T4SQLDB"
providerName="System.Data.SqlClient"
connectionString="Data Source=.\SQLEXPRESS;Initial Catalog=T4SQLDB;Integrated Security=True"
/>
</connectionStrings>
<appSettings>
<add
key="Engine_Package"
value="T4SQL.ENGINE_"
/>
</appSettings> |
- Different config for Oracle
<connectionStrings>
<add
name="T4SQLDB"
providerName="Oracle.ManagedDataAccess.Client"
connectionString="Data Source=ORCL;User Id=/"
/>
</connectionStrings>
<appSettings>
<add
key="Engine_Package"
value="T4SQL.ENGINE."
/>
</appSettings> |
T4SQL Template Engine will load all add-ins template libraries under the "Templates" subdirectory on startup.
When you get some new Template Libraries and want to plug them into your engine, just copy their .dll files into the "Templates" subdirectory and restart the engine service. The engine will upload templates' metadata into database T4SQL.TEMPLATE_CLASS table
and T4SQL.TEMPLATE_SPEC table, all new templates are ready for every workspaces to use.
Template Library
T4SQL Template Library is a library of T4SQL Templates, each T4SQL Template Library presents as an add-in .dll for T4SQL Template Engine to load. A built-in T4SQL Template Library is shipped with the T4SQL Template Engine, including
about ten T4SQL Templates in the initial release.
You would be interested in being a Supplier of T4SQL Template Libraries. The following section introduces how to author a T4SQL Template.
Template Authoring
Every T4SQL Template is made by
Preprocessed T4 Text Template. To author a T4SQL Template, you can start with a .NET class which is generated by a Preprocessed T4 Text Template. A T4 Text Template becomes a T4SQL Template when its partial class conforms to a standard for T4SQL Template
interaction. This standard is provided through the ITemplate interface. Any class that implements the ITemplate interface is a T4SQL Template.
In practice, there is a NuGet package
T4SQL.Base which prepares all necessary scaffolding for you.
Once the
T4SQL.Base package is installed into your class library project, the
T4SQL.Base.dll will be added into project references, at the same time a Visual Studio Item Template "
T4SQL Template" will be installed as well if it does not yet exist, this is a "template of template" to
make the template authoring as simple as possible.
- T4SQL.Base.dll, this class library provides:
- ITemplate interface (for code generation) and
ITemplateProperties interface (for publishing T4SQL Template properties metadata to database side workspaces).
- Utility extension methods for string parse, collections, etc.
- Database metadata retrieval, such as:
Expanding or infering * to a explicit column list of a table;
Traversing foreign key relation-chain for a root table.
- Visual Studio Item Template:
- Add a new T4SQL Template item into the class library project,
Notes:
Please remain the file name extension .tt unchanged, and don't contain any spaces or punctuation in the main part of the file name. For example "My T4SQL Template.tt" would be incorrect, but "MyT4SQLTemplate.tt" is correct. The file name will
be used as a class name in the generated code.
- When you save the .tt file, four subsidiary files .cs,
.partial.cs, .SqlServer.sql and .Oracle.sql will be generated. To see these files in Solution Explorer, expand the
.tt file node.
| File |
Description |
| .tt |
Don't need to make any changes in this master file unless you want to support more databases other than SQL Server and Oracle. |
| .cs |
This code is generated by TextTemplatingFilePreprocessor, you can't do anything in this file. |
| .Oracle.sql |
The SQL text template for Oracle. |
| .partial.cs |
This is a critical work on C# code, it's recommended to encapsulate all necessary variables and complex text preprocessor (which will be used in your T4 SQL text templates - .Oracle.sql and .SqlServer.sql) into this partial class, to achieve a better separation
between the text presentation and the underlying logic. The scaffolding code will give you some sample for quick start. |
| .SqlServer.sql |
The SQL text template for SQL Server. |
A good way to create a T4 SQL text template is to convert an existing tested example of the SQL script.
The following figure shows their internal relationships:
- Since .SqlServer.sql file and .Oracle.sql file are included in .tt file, Visual Studio TextTemplatingFilePreprocessor can't detect any change in these .sql files. So after you make changes in .SqlServer.sql and/or .Oracle.sql file(s), please always re-generate
.cs file by right-click the .tt file, and then click Run Custom Tool before Build or Rebuild the project.
- Naming Conventions
Although the scaffolding code initialized by Visual Studio Item Template - T4SQL Template is a database view object as default, however the object type is not limited to view. Your T4SQL Template can generate any database object
types.
The following are naming conventions for T4SQL Template class name (.tt file name).
| Prefix |
Object Type |
| V |
View |
| P |
PL/SQL Package (Oracle) |
| S |
Stored Procedure |
| F |
Function |
| T |
Table |
Considering for compatibility with multiple database platforms (i.e. SQL Server and Oracle), It is recommended to limit object names in 30 characters.
For namespaces, just be well-organized and meaningful.
Database side developers will use the fully-qualified name
(Namespaces.ClassName) as T4SQL Template name in their T4SQL workspaces, so it’s necessary to keep names simple.
Samples
- T4SQL Workspaces Samples
Enclosed in distribution files, a separate setup script test_create.sql is used to install a complete workspaces sample in the
test schema, which includes workspace creation, workitem/properties settings and some example tables to test built-in T4SQL Templates.
- Template Authoring Samples
The built-in T4SQL Template Library is also a straightforward sample of template authoring. Please download the source code from
[SOURCE CODE] tab.
Template Library Reference
At the moment, please refer to result data of test.VW_sample_properties and source code of the built-in T4SQL Template Library.
System Requirements

Motorola Razr Poses For FCC Hours Ahead Of Release Confirming Previous Leaks
by Brandon HillMotorola's Moto Razr is almost here folks; and that point is even more evident by the smartphone's appearance at the Federal Communications Commission (FCC). As is often the case with unreleased smartphones, these FCC "leaks" often give us a great look at what we can expect when the product begins shipping.
The FCC images confirm all of the previously leaked renders that we've seen concerning the Moto Razr, including its clamshell design that harks back to the original Moto Razr flip-phone family. We can also see an elongated, unbroken portrait-style display that folds when not in use.
Additional images from the FCC show the smartphone with its display unfolded from the right and left sides, along with views of the top and bottom of the smartphone. The bottom shot in particular confirms a rather thick "chin" that we would assume holds a portion of the battery along with the visible USB-C port.
Separately, Motorola has updated its Twitter profile to show a darkened image of the Moto Razer opened from the side. The image looks identical to renders that leaked in late October.
According to previous leaks, the Moto Razr is expected to feature a 6.2-inch folding display along with an 800x600 cover display. The smartphone is allegedly powered by a QualcommSnapdragon 710 SoC in 4GB/64GB (RAM/storage) or 6GB/128GB configurations. Additionally, it's expected that the Moto Razr will have a 2730 mAh non-removable battery.
Motorola is expected to fully reveal the Moto Razr later today, and we’ll update this article with the official information at that time.

Three days into my YWCA YWEB class and I feel like I might get the hang of this after all. Having never seen this before I am proud I have come this far. It is strange looking at code when you've never seen it before. I am trying to figure out if this is something I can grasp enough to carve out a career or maybe use as a spring board to sustain myself while I continue pursuing my passion. I am a writer first and foremost so it will be interesting to see where this thread takes me.
Right now I am wondering if I could benefit from Code Academy or Khan Academy so I can immerse myself in this world.


The Dynamo Controller Backend¶
This section isn’t necessary to know in order to use Dynamo. It is explaining encapsulated code within the package that you don’t actually need to see, but it might be helpful to understand what is going on when you create a model with Dynamo. Again, I would recommend watching the Quick Start video on the homepage of the documentation to get a better understanding.
The Dynamo Controller class contains CRUD functions similar to the functions of a Resource route in Laravel. Recall that when you create a Dynamo object with the command,
php artisan make:dynamo FaqCategory
Dynamo will generate a route in your routes->web.php file,
Route::resource('faqcategory', '\App\Http\Controllers\Admin\FaqCategoryController');
that links to the Dynamo Controller. The following routes are generated in your Laravel application that you can see by running php artisan route:list:
The index function returns an index view or table of all the resources for that module. So in the Faq Category example, the index function would show a view of all the Faq Categories saved in the database:
public function index()
{
$items = $this->dynamo->getIndexItems();
return DynamoView::make($this->dynamo, 'dynamo::index', compact('items'));
}
Resulting DynamoView( screenshot is bootstrap3 theme instead of bootstrap4 ):
The next two functions are create() and store(). Create shows the form view that the user will use to create Faq Category objects:
public function create()
{
$item = new $this->dynamo->class;
$formOptions = [
'route' => $this->dynamo->getRoute('store'),
'files' => true,
];
return DynamoView::make($this->dynamo, 'dynamo::form', compact('item', 'formOptions'));
}
Resulting DynamoView:
Store() is the function that gets hit when the user presses the submit button on the Create an Faq Category form. Store will “store” this new Faq Category object in your database:
public function store(Request $request)
{
$item = new $this->dynamo->class;
$this->dynamo->store($item);
session(['alert-success' => $this->dynamo->getName() . ' was saved successfully!']);
return redirect()->route($this->dynamo->getRoute('edit'), $item->id);
}
Resulting DynamoView:
The next two functions are edit() and update() which go hand-in-hand the same way create() and store() go hand-in-hand. When the user clicks the edit button on one of the Faq Category objects in the index view, the form view for that particular employee will be presented to the user so they can make changes to that Faq Category (perhaps update a phone number, or in this case update the name of the category):
public function edit($id)
{
$className = $this->dynamo->class;
$item = $className::withoutGlobalScopes()->find($id);
$formOptions = [
'route' => [$this->dynamo->getRoute('update'), $id],
'method' => 'put',
'files' => true,
];
return DynamoView::make($this->dynamo, 'dynamo::form', compact('item', 'formOptions'));
}
Update() gets hit when the user presses the Submit button and whatever changes they made will get updated for that particular Faq Category in the database:
public function update(Request $request, $id)
{
$className = $this->dynamo->class;
$item = $className::withoutGlobalScopes()->find($id);
$this->dynamo->store($item);
session(['alert-success' => $this->dynamo->getName() . ' was saved successfully!']);
return redirect()->route($this->dynamo->getRoute('edit'), $id);
}
The final function on the Dynamo Controller is destroy(). This function gets hit when the user clicks the delete button in the index view, and an alert will appear asking them if they are sure they want to do this. If they press yes, the item will attempt to be deleted. If the item can’t be deleted due to throwing a QueryException (because you can’t add or update a child row if another object in the database is using it for a foreign key), it will redirect and say you can’t do that because this object is in use. Otherwise, the item will be deleted and they will be shown a success message, and this Employee no longer exist:
public function destroy($id)
{
$className = $this->dynamo->class;
// Run through and look for fields with type 'multiSelect'
foreach($this->dynamo->getFields() as $field) {
if($field->type == 'hasMany') {
//if 'multiSelect' found then relational data may exist. Detach data from the model
$className::withoutGlobalScopes()->find($id)->{$field->key}()->detach();
}
}
$item = $className::withoutGlobalScopes()->findOrFail($id);
try {
$item->delete();
} catch (QueryException $e) {
session(['alert-danger' => $this->dynamo->getName() . ' cannot be deleted while in use!']);
return redirect()->route($this->dynamo->getRoute('index'));
}
session(['alert-warning' => $this->dynamo->getName() . ' was deleted successfully!']);
return redirect()->route($this->dynamo->getRoute('index'));
}
Resulting DynamoView if object can’t be deleted because it’s connected to other objects in the relational database via pivot tables:
Resulting DynamoView if object was successfully deleted:


Property Files
Keystone Source Search can be easily extended to support styling for other languages using special property files. These are simply text files that provide lexer, keyword, and styling options for the Scintilla control. These are similar to, but not as sophisticated as, the property files used with the sciTE editor.
File Locations
KSS searches for the special property files in two locations:
%ProgramFiles%/Keystone Computer Resources/KSS - this folder is reserved for special property files
that may be shipped as part of the basic product. These files should not be modified.
%AppData%/Keystone Computer Resources/KSS - this folder is reserved for user defined special property files. Property files in this folder override similarly named property files located in the %ProgramFiles%/Keystone Computer Resources/KSS folder.
File Names
Property files have a required naming format which is language.properties where language
is the name that will appear on the KSS File Mode menu.
File Contents
Blank lines and Clarion style comments, line begins with a !, are ignored.
The first non-comment line in the file should specify the lexer to be used like this:
Lexer=lexer_name
where lexer_name is one of clarion, cpp, html, or text; these are
the only lexers currently supported. Invalid values are equated to text.
The remainder of the file contents are organized into sections denoted by [ ] and followed by the data for that section. Data for each section can be specified on multiple lines. Sections should be laid out in the following order:
[FilePatterns]
Specify each of the file patterns, separated by a space, to be associated with this property file.
If the same extension appears in multiple property files, only the first occurrance found will be used.
The property files are processed alphabetically.
example:
[FilePatterns]
*.xml *.xsl *.svg *.xul *.xsd *.dtd
*.xslt *.axl *.xrc *.rdf
[Options]
A lexer may have special options that control its behaviour. Use this section to specify the lexer
options, one per line. The format for this section is option, "=", the option value, ";",
the option description.
example:
fold=1;Folding is turned on by setting fold=true.
[Keywords#]
Each lexer uses different sets of keywords to provide its functionality. The # refers to the
Scintilla keyword list that is to contain the specified keywords. Depending on the lexer, the case of
the keywords can be significant. Most lexers use lower case, however, the Clarion lexer requires upper
case keywords.
example:
! Comment that describes Keyword Set
[Keywords1]
abstract as ascending base bool break by byte case catch char checked
class const continue decimal default delegate descending do double else enum
equals event explicit extern false finally fixed float for foreach from goto group if
! Comment that describes Keyword Set
[Keywords2]
file group region
[Styles]
The lexers determine a style number for each lexical type, such as keyword, comment or number. These
settings determine the visual style to be used for each style number of each lexer.
The value of each setting is a set of ',' separated fields, some of which have a subvalue after a ':'. Each lexer uses several styles to highlight various aspects of the text. The styles are numbered and can contain the following, comma separated, values in any order:
Style#=font:font_name,size:font_size,bold,italic,underline,fore:fore_color,back:back_color ,eolfilled,case:case_opt,hide,hotspot
Style#= specify the style number being defined.
font:font_name specify the name of the font to be used
size:font_size specify the point size of the font
bold specify this for a bold font style
italic specify this for an italic font style
underline specify this for an underline font effect
fore:fore_color specify the foreground color as a hexadecimal rgb value [#RRGGBB]
back:back_color specify the background color as a hexadecimal rgb value [#RRGGBB]
eolfilled if the last character in the line has a style with this attribute set, the remainder of the line up to the right edge of the window is filled with the background colour set for the last character. This is useful when a document contains embedded sections in another language such as html pages with embedded JavaScript.
case:case_opt specify 0 for Mixed Case, 1 for Upper Case, or 2 for Lower Case
hide specify this if the lexical type is to be hidden
hotspot specify this if the lexical type is to act like a hyperlink. Within KSS, this is only useful for the Clarion lexer. Hotspots attempt to display the Clarion Help for the lexical type.
example:
[Styles]
! <Default>
use this format for the Default style to cause it to sort to the top of
the list
style32=font:Verdana,size:10
! Doc Comment Line: line comments beginning with /// or //!.
style15=fore:#3F703F,font:Comic Sans MS,size:9

How to Play Ambient Sounds on HomePod
by Tim HardwickApple released a new 13.2.1 HomePod software update in October 2019 that brings the ability to play relaxing high-quality soundtracks with Ambient Sounds. This article explains how to use them.
The software update will be installed automatically on the HomePod, but you can also manually update and check your software version by following the instructions in our HomePod software how-to.
How to Play Ambient Sounds on HomePod
The Ambient Sounds feature offers seven continuous streaming options. They include the following:
- Rain
- Stream
- White Noise
- Fireplace
- Forest
- Night
- Ocean
To start streaming one of the sounds on your HomePod, simply ask Siri. To play White Noise for example, you would say "Hey Siri, play white noise sounds."
You can also get HomePod to play a random ambient sound by saying "Hey Siri, play sounds."
How to Set a Sleep Timer on HomePod
Additionally, you can play an ambient sound and set a sleep timer so that it automatically stops playing after a certain period of time has passed.
First, get HomePod to play an ambient sound using one of the phrases above, then say "Hey Siri, set a sleep timer for 45 minutes," or however long you want it to play for.
If you listen to the HomePod's ambient sounds very carefully, you may notice that they loop after about 15 minutes, but it's not something you're likely to pick up on if you're using them as background audio for focus or relaxation.

What Lies Beneath
What Lies Beneath is a movie starring Harrison Ford, Michelle Pfeiffer, and Katharine Towne.


In the novel Things Fall Apart, Pulitzer Prize-winner Chinua Achebe crafts the story of his central character, Okonkwo, an Igbo tribesman that lives during the European colonization of Africa. Through analyzing Achebe’s text, we will explore the following question: What does it mean for things to fall apart? We will examine the internal and external factors that influence and define who we become and how we make choices in our lives through the lens of the characters in Achebe’s novel. Our work will culminate with an expository essay that analyzes these forces in Okonkwo’s life.
Refer to this document as needed to understand the goals and content of the unit.
Central Question: What does it mean for things to fall apart?
Culminating Task Prompt: Write a character analysis of Okonkwo. In your analysis, consider how internal and external factors influence his relationships and contribute to his fate at the end of the novel. In your response, be sure to do the following:
This is the anchor text of the unit. You will have a hard copy of this text available to you..
This text will help you understand Igbo culture so that you will have the necessary background knowledge to understand the characters, events, and ideas of Things Fall Apart.
This poem is the source for the title of the novel Things Fall Apart. You will read this text in the unit to understand why it might be used as a source for the novel’s title.
Throughout the unit, take notes on the following characters on the attached character note-taking tool.
1. Okonkwo
2. Unoka
3. Okoye
4. Ikemefuna
5. X
6. XX
Throughout the unit, document words or concepts that you do not know or that you think are important to learn and practice. You might use context clues from the text you are reading to assist in determining what the words mean. You might also consult a dictionary or other reference material. Many words or concepts have more than one meaning, so be sure to think about the context in which they are used to determine the most accurate meaning. Some words may be provided by your teacher, but you should also note any other words you find interesting.

Mail::Toaster::DNS - DNS functions, primarily to test RBLs
A set of subroutines for testing rbls to verify that they are functioning properly. If Net::DNS is installed it will be used but we can also test using dig.
These functions are used by toaster-watcher to determine if RBL's are available when generating qmail's smtpd/run control file.
Create a new DNS method:
use Mail::Toaster;
use Mail::Toaster::DNS;
my $dns = Mail::Toaster::DNS->new;
After the demise of osirusoft and the DDoS attacks currently under way against RBL operators, this little subroutine becomes one of necessity for using RBL's on mail servers. It is called by the toaster-watcher.pl script to test the RBLs before including them in the SMTP invocation.
my $r = $dns->rbl_test(conf=>$conf, zone=>"bl.example.com");
if ($r) { print "bl tests good!" };
arguments required:
zone - the zone of a blacklist to test
Tests to make sure that name servers are found for the zone and then run several test queries against the zone to verify that the answers it returns are sane. We want to detect if a RBL operator does something like whitelist or blacklist the entire planet.
If the blacklist fails any test, the sub will return zero and you should not use that blacklist.
my $count = $t_dns->rbl_test_ns(
conf => $conf,
rbl => $rbl,
);
arguments required:
rbl - the reverse zone we use to test this rbl.
This script requires a zone name. It will then return a count of how many NS records exist for that zone. This sub is used by the rbl tests. Before we bother to look up addresses, we make sure valid nameservers are defined.
$t_dns->rbl_test_positive_ip( rbl=>'sbl.spamhaus.org' );
arguments required:
rbl - the reverse zone we use to test this rbl.
arguments optional:
conf
A positive test is a test that should always return a RBL match. If it should and does not, then we assume that RBL has been disabled by its operator.
Some RBLs have test IP(s) to verify they are working. For geographic RBLs (like korea.services.net) we can simply choose any IP within their allotted space. Most other RBLs use <IP_ADDRESS> as a positive test.
In the case of rfc-ignorant.org, they have no known test IPs and thus we have to skip testing them.
$t_dns->rbl_test_negative_ip(conf=>$conf, rbl=>$rbl);
This test is a little more difficult as RBL operators don't typically have an IP that is whitelisted. The DNS location based lists are very easy to test negatively. For the rest I'm listing my own IP as the default unless the RBL has a specific one. At the very least, my site won't get blacklisted that way. ;) I'm open to better suggestions.

You can find the sed
scripts in this GitHub repository
Problem Substitute all the occurences of
Public <something> as <type>
with
Public Readonly Property <something> as <type>
Get
Return _source.<something>
end Get
End Property
Solution Under Visual Studio, in the Find/Replace dialog, the match pattern is
Public {[^ ]+} as {.#}\n
The replace pattern is
Public Readonly Property \1 as \2 \ Get \n Return _source\.\1 \n End Get \n End Property
Under sed
on OS X you need this expression
s:Public \([^ ][^ ]*\) as \(.*\):Public Readonly Property \1 As \2\
Get\
Return _source\.\1\
End Get\
End Property\
:
The interesting part is that you cannot use \+
to match one or more character, it seems that
this is a GNU extension and it is not found in the version shipped in OS X (derived from the one
in FreeBSD).
The exercise is contained in the property
folder.
