The TypeRegistry class maintains all the assigned TypeHandles in a given system.
There should be only one TypeRegistry class during the lifetime of the application. It will be created on the local heap initially, and it should be migrated to shared memory as soon as shared memory becomes available.
| __init__ | ( | const | TypeRegistry | ) |
| TypeHandle findType | ( | str | name | ) |
Looks for a previously-registered type of the given name.
Returns its TypeHandle if it exists, or TypeHandle::none() if there is no such type.
| TypeHandle findTypeById | ( | int | id | ) |
Looks for a previously-registered type with the given id number (as returned by TypeHandle::get_index()).
Returns its TypeHandle if it exists, or TypeHandle::none() if there is no such type.
| TypeHandle getChildClass | ( | TypeHandle | child, |
| int | index | ||
| ) |
Returns the nth child class of this type.
The index should be in the range 0 <= index < get_num_child_classes().
| str getName | ( | TypeHandle | type, |
| TypedObject | object | ||
| ) |
Returns the name of the indicated type.
The "object" pointer is an optional pointer to the TypedObject class that owns this TypeHandle. It is only used in case the TypeHandle is inadvertantly undefined.
| int getNumChildClasses | ( | TypeHandle | child, |
| TypedObject | child_object | ||
| ) |
Returns the number of child classes that the indicated type is known to have.
This may then be used to index into get_child_class().
The "object" pointer is an optional pointer to the TypedObject class that owns this TypeHandle. It is only used in case the TypeHandle is inadvertantly undefined.
| int getNumParentClasses | ( | TypeHandle | child, |
| TypedObject | child_object | ||
| ) |
Returns the number of parent classes that the indicated type is known to have.
This may then be used to index into get_parent_class(). The result will be 0 if this class does not inherit from any other classes, 1 if normal, single inheritance is in effect, or greater than one if multiple inheritance is in effect.
The "object" pointer is an optional pointer to the TypedObject class that owns this TypeHandle. It is only used in case the TypeHandle is inadvertantly undefined.
| int getNumRootClasses | ( | ) |
Returns the number of root classes–that is, classes that do not inherit from any other classes–known in the system.
| int getNumTypehandles | ( | ) |
Returns the total number of unique TypeHandles in the system.
| TypeHandle getParentClass | ( | TypeHandle | child, |
| int | index | ||
| ) |
Returns the nth parent class of this type.
The index should be in the range 0 <= index < get_num_parent_classes().
| TypeHandle getParentTowards | ( | TypeHandle | child, |
| TypeHandle | base, | ||
| TypedObject | child_object | ||
| ) |
Returns the parent of the indicated child class that is in a direct line of inheritance to the indicated ancestor class.
This is useful in the presence of multiple inheritance to try to determine what properties an unknown type may have.
The "object" pointer is an optional pointer to the TypedObject class that owns this TypeHandle. It is only used in case the TypeHandle is inadvertantly undefined.
| TypeHandle getRootClass | ( | int | n | ) |
Returns the nth root class in the system.
See get_num_root_classes().
| list getRootClasses | ( | ) |
| TypeHandle getTypehandle | ( | int | n | ) |
Returns the nth TypeHandle in the system.
See get_num_typehandles().
| list getTypehandles | ( | ) |
| bool isDerivedFrom | ( | TypeHandle | child, |
| TypeHandle | base, | ||
| TypedObject | child_object | ||
| ) |
Returns true if the first type is derived from the second type, false otherwise.
The "child_object" pointer is an optional pointer to the TypedObject class that owns the child TypeHandle. It is only used in case the TypeHandle is inadvertently undefined.
This function definition follows the definitions for look_up() and freshen_derivations() just to maximize the chance the the compiler will be able to inline the above functions. Yeah, a compiler shouldn't care, but there's a big different between "shouldn't" and "doesn't".
|
static |
Returns the pointer to the global TypeRegistry object.
| recordAlternateName | ( | TypeHandle | type, |
| str | name | ||
| ) |
Indicates an alternate name for the same type.
This is particularly useful when a type has changed names, since the type is stored in a Bam file by name; setting the original name as the alternate will allow the type to be correctly read from old Bam files.
| recordDerivation | ( | TypeHandle | child, |
| TypeHandle | parent | ||
| ) |
Records that the type referenced by child inherits directly from the type referenced by parent.
In the event of multiple inheritance, this should be called once for each parent class.
| recordPythonType | ( | TypeHandle | type, |
| object | python_type | ||
| ) |
Records the given Python type pointer in the type registry for the benefit of interrogate, which expects this to contain a Dtool_PyTypedObject.
| TypeHandle registerDynamicType | ( | str | name | ) |
Registers a new type on-the-fly, presumably at runtime.
A new TypeHandle is returned if the typename was not seen before; otherwise the same TypeHandle that was last used for this typename is returned.
|
static |
Walks through the TypeRegistry tree and makes sure that each type that was previously registered is still registered.
This seems to get broken in certain circumstances when compiled against libc5–it is as if the static initializer stomps on the _type_handle values of each class after they've been registered.
| write | ( | Ostream | out | ) |
Makes an attempt to format the entire TypeRegistry in a nice way that shows the derivation tree as intelligently as possible.
| TypeHandle root_classes[] |
Returns the nth root class in the system.
See get_num_root_classes().
| TypeHandle typehandles[] |
Returns the nth TypeHandle in the system.
See get_num_typehandles().

Native PHP extensions are compiled into *.so files, and can be enabled by adding a line to the core php.ini configuration file - or one of the additional configuration files that are loaded by PHP. If you do not know where you can find the PHP configuration file(s) on your system, you can run the following command from the command line:
php --ini
Extensions are enabled by adding "extension=name.so" lines to the configuration file - where 'name' should of course be replaced by the name of your extension. A default PHP installation already comes with many default extensions, so in the configuration file(s) on your system you will certainly find a number of these "extension=name.so" lines.
The extension lines either take an absolute path ("extension=/path/to/extension.so") or a relative path ("extension=extension.so"). If you'd like to use relative paths, you must make sure that you've copied your extension *.so file to the default extension directory, so that PHP can find it. To find out this default extension directory, use the following command line instruction:
php -i|grep extension_dir
When PHP starts, it loads its configuration file(s) and for each "extension=name.so" line in it, it will open the appropriate library, and call the "get_module()" function from it. Each extension library must therefore define and implement this "get_module()" C function. The function is called by PHP right after the library is loaded (and thus way before pageviews are handled), and it should return a memory address that points to a structure that holds information about all functions, classes, variables and constants that are made available by the extension.
The structure that the get_module() returns is defined in the header files of the Zend engine, but it is a pretty complicated structure without good documentation. Luckily, the PHP-CPP library makes life easier for you, and offers an Extension class that can be used instead.
#include <phpcpp.h>
extern "C" {
PHPCPP_EXPORT void *get_module() {
static Php::Extension myExtension("my_extension", "1.0");
return myExtension.module();
}
}
In the example above you see a very straightforward implementation of the get_module() function. A number of elements require special attention. For a start, the only header file that you see is the phpcpp.h header file. If you're using the PHP-CPP library to build your own extensions, you do not have to include the complicated, unstructured, and mostly undocumented header files of the Zend engine - all you need is the single header file of the PHP-CPP library. If you insist, you are of course free to also include the header files of the core PHP engine - but you do not have to.
The PHP-CPP library is a C++ library, and you can use all features of this language. However, PHP expects your library, and especially your get_module() function, to be implemented in C and not in C++. That's why we've wrapped the get_module() function in an 'extern "C"' block. This will instruct the C++ compiler that the get_module() is a regular C function, and no C++ name mangling should be applied to it.
The PHP-CPP library defines a "PHPCPP_EXPORT" macro that should be placed in front of the get_module() function. This macro makes sure that the get_module() function is publicly exported, and thus callable by PHP. The macro has a different implementation based on the compiler and operating system.
Inside the get_module() function the Extension object is instantiated, and the Extension::module() method is called. It is crucial that you make a static instance of this Extension class, because the object should exist for the entire lifetime of the PHP process, and not only for the duration of the get_module() call. The constructor takes two arguments: the name of your extension and its version number. The Extension::module() method returns the memory address that PHP needs to initialize the library.
Note that the example above does not yet make any native functions or native classes available in PHP - it only creates the extension.
An extension is of course only useful if you define functions and/or classes that can be accessed from PHP scripts. For functions you can do this by adding your native function implementations to the Extension object:
#include <phpcpp.h>
extern void example1();
extern void example2(Php::Parameters ¶ms);
extern Php::Value example3();
extern Php::Value example4(Php::Parameters ¶ms);
extern "C" {
PHPCPP_EXPORT void *get_module() {
static Php::Extension myExtension("my_extension", "1.0");
myExtension.add("native1", example1);
myExtension.add("native2", example2);
myExtension.add("native3", example3);
myExtension.add("native4", example4);
return myExtension.module();
}
}
What do we see here? We've added four function declarations ("example1", "example2", "example3" and "example4") to the source code of our extension. The reason why we've only declared the functions, and not fully implemented them is to keep the example code relatively small. We assume that the four example functions are implemented in a different file. In a real world example you could just as well remove the "extern" keyword and implement the four functions in the same source file as the get_module() call.
The four functions all have a different signature: Some return a value, while others do not return anything. And some take parameters, while others do not. Despite the different signature of the functions, they can all be made available in PHP by adding them to the extension object, by simply calling the myExtension.add() method. This method takes two parameters: the name by which the function should be accessible in PHP, and the actual native function.
In the example above we've used different names for the native functions ("example1" up to "example4") as for the PHP functions ("native1" to "native4"). This is legal - you do not have to use the same names for your native functions as for your PHP functions. The following PHP script can be used to call the four native functions:
<?php
native1();
native2("a","b");
$x = native3();
$y = native4(1,2);
?>
The signature of the four example functions are exactly the signatures that are supported by the PHP-CPP libraries. Every native function that returns void or a Php::Value object, and that either accepts a Php::Parameters object or no parameters at all, can be added to the extension object and can thus be exported to PHP.
Variables in PHP are non-typed. A variable can thus hold any possible type: an integer, string, a floating point number, and even an object or an array. C++ on the other hand is a typed language. In C++ an integer variable always has a numeric value, and a string variable always hold a string value.
When you mix native code and PHP code, you will need to convert the non-typed PHP variables into native variables, and the other way round: convert native variables back into non-typed PHP variables. The PHP-CPP library offers the "Value" class that makes this a very simple task.

int socket(int domain, int type, int protocol);
The domain argument specifies a communication domain; this selects the protocol family which will be used for communication. These families are defined in <sys/socket.h>. The formats currently understood by the Linux kernel include:
| Name | Purpose | Man page |
| AF_UNIX | Local communication | unix (7) |
| AF_LOCAL | Synonym for AF_UNIX | |
| AF_INET | IPv4 Internet protocols | ip (7) |
| AF_AX25 | Amateur radio AX.25 protocol | . ax25 (4) |
| AF_IPX | IPX - Novell protocols | |
| AF_APPLETALK | AppleTalk | ddp (7) |
| AF_X25 | ITU-T X.25 / ISO-8208 protocol | x25 (7) |
| AF_INET6 | IPv6 Internet protocols | ipv6 (7) |
| AF_DECnet | DECet protocol sockets | |
| AF_KEY | Key management protocol, originally developed for usage with IPsec | |
| AF_NETLINK | Kernel user interface device | netlink (7) |
| AF_PACKET | Low-level packet interface | packet (7) |
| AF_RDS | . Reliable Datagram Sockets (RDS) protocol | . . rds (7) rds-rdma (7) |
| AF_PPPOX | Generic PPP transport layer, for setting up L2 tunnels (L2TP and PPPoE) | |
| AF_LLC | . Logical link control (IEEE 802.2 LLC) protocol | |
| AF_IB | . InfiniBand native addressing | |
| AF_MPLS | . Multiprotocol Label Switching | |
| AF_CAN | . Controller Area Network automotive bus protocol | |
| AF_TIPC | . TIPC, "cluster domain sockets" protocol | |
| AF_BLUETOOTH | . Bluetooth low-level socket protocol | |
| AF_ALG | . Interface to kernel crypto API | |
| AF_VSOCK | . VSOCK (originally "VMWare VSockets") protocol for hypervisor-guest communication | vsock (7) |
| AF_KCM | . KCM (kernel connection multiplexor) interface | |
| AF_XDP | . XDP (express data path) interface |
Further details of the above address families, as well as information on several other address families, can be found in address_families(7).
The socket has the indicated type, which specifies the communication semantics. Currently defined types are:
Some socket types may not be implemented by all protocol families.
Since Linux 2.6.27, the type argument serves a second purpose: in addition to specifying a socket type, it may include the bitwise OR of any of the following values, to modify the behavior of socket():
The protocol specifies a particular protocol to be used with the socket. Normally only a single protocol exists to support a particular socket type within a given protocol family, in which case protocol can be specified as 0. However, it is possible that many protocols may exist, in which case a particular protocol must be specified in this manner. The protocol number to use is specific to the “communication domain” in which communication is to take place; see protocols(5). See getprotoent(3) on how to map protocol name strings to protocol numbers.
Sockets of type SOCK_STREAM are full-duplex byte streams. They do not preserve record boundaries. A stream socket must be in a connected state before any data may be sent or received on it. A connection to another socket is created with a connect(2) call. Once connected, data may be transferred using read(2) and write(2) calls or some variant of the send(2) and recv(2) calls. When a session has been completed a close(2) may be performed. Out-of-band data may also be transmitted as described in send(2) and received as described in recv(2).
The communications protocols which implement a SOCK_STREAM ensure that data is not lost or duplicated. If a piece of data for which the peer protocol has buffer space cannot be successfully transmitted within a reasonable length of time, then the connection is considered to be dead. When SO_KEEPALIVE is enabled on the socket the protocol checks in a protocol-specific manner if the other end is still alive. A SIGPIPE signal is raised if a process sends or receives on a broken stream; this causes naive processes, which do not handle the signal, to exit. SOCK_SEQPACKET sockets employ the same system calls as SOCK_STREAM sockets. The only difference is that read(2) calls will return only the amount of data requested, and any data remaining in the arriving packet will be discarded. Also all message boundaries in incoming datagrams are preserved.
SOCK_DGRAM and SOCK_RAW sockets allow sending of datagrams to correspondents named in sendto(2) calls. Datagrams are generally received with recvfrom(2), which returns the next datagram along with the address of its sender.
SOCK_PACKET is an obsolete socket type to receive raw packets directly from the device driver. Use packet(7) instead.
An fcntl(2) F_SETOWN operation can be used to specify a process or process group to receive a SIGURG signal when the out-of-band data arrives or SIGPIPE signal when a SOCK_STREAM connection breaks unexpectedly. This operation may also be used to set the process or process group that receives the I/O and asynchronous notification of I/O events via SIGIO. Using F_SETOWN is equivalent to an ioctl(2) call with the FIOSETOWN or SIOCSPGRP argument.
When the network signals an error condition to the protocol module (e.g., using an ICMP message for IP) the pending error flag is set for the socket. The next operation on this socket will return the error code of the pending error. For some protocols it is possible to enable a per-socket error queue to retrieve detailed information about the error; see IP_RECVERR in ip(7).
The operation of sockets is controlled by socket level options. These options are defined in <sys/socket.h>. The functions setsockopt(2) and getsockopt(2) are used to set and get options.
Other errors may be generated by the underlying protocol modules.
The SOCK_NONBLOCK and SOCK_CLOEXEC flags are Linux-specific.
socket() appeared in 4.2BSD. It is generally portable to/from non-BSD systems supporting clones of the BSD socket layer (including System V variants).
The manifest constants used under 4.x BSD for protocol families are PF_UNIX, PF_INET, and so on, while AF_UNIX, AF_INET, and so on are used for address families. However, already the BSD man page promises: "The protocol family generally is the same as the address family", and subsequent standards use AF_* everywhere.

Voxel Dungeons is a game originally conceptualised in the Game Development Society at the Preston Campus of the University of Central Lancashire.
It is a Voxel-based game with RPG elements with features similar to that of Dungeons and Dragons. The intention for this project is to create a game that is similar to a cross between DND and early Maplestory but with a more complex stat system allowing for minimaxing and a strategic playstyle.
We are a team of Computing students at the University of Central Lancashire in Preston, England. We come from many different backgrounds and have an amazing wealth of knowledge between us. The game idea itself is the brainchild of Jack Grover who pitched the idea to our friendship group. Those of us interested joined him and began working on parts of the game in which we had experience or that complemented our chosen course.


3.0.0-0
A framework for creating and running data pipelines. Data pipelines have stages, which are made of an arbitrary number of tasks. Stages and tasks are run in serial: once a task completes, the next task in the pipeline is executed.
Pipelines take a data object as input, and each task operates on the object in some way.
For an example of the Pipeliner in action, checkout the nxus-static-site module.
> npm install @nxus/pipeliner --save
app.get('pipeliner').pipeline('my-pipeline')
By default, every pipeline is pre-configured with three stages: 'collect', 'process', 'generate'. However, you can define your own stages:
app.get('pipliner').stages('my-pipeline', ['stage1', 'stage2', 'stage3'])
A task is a javascript function that accepts any objects passed into the pipeline when it is run.
let myTask = (word) => {
word.toUpperCase();
}
app.get('pipeliner').task('my-pipeline', 'process', myTask)
Once all the tasks for a pipeline have been defined, the last step is to run the pipeline.
app.get('pipeliner').run('my-pipeline', someData)
let myTask = (data) => {
data.word.toUpperCase()
}
let data = {word: 'hello'}
let pipeliner = app.get('pipeliner')
pipeliner.pipeline('capitalize')
pipeliner.task('capitalize', 'process', myTask)
pipeliner.run('capitalize', data).then(() => {
console.log('data') // {word: 'HELLO'}
})

Lookup and authentication for websocket services
App instances can provide services on incoming appwebsocket connections that can be used by the PBX or other app instances.
Those services are JSON APIs that are identified by a string. For ensuring the uniqueness, we recommend using the reverse domain name notation like "com.innovaphone.provisioning".
See the documentation of AppWebsocket::AppWebsocketServiceInfo
on how to publish services.
If you want to find and authenticate against one of those services you can use this library. After attaching it to the websocket connection from the PBX you can
- get the available services and their websocket URLs for a given service id.
- get an authentication for a service from the PBX.

Professional Fortnite Player Banned For Life Over Cheat
by Lucy ConnollyA professional Fortnite player has received a lifetime ban from playing the video game after he was caught cheating.
Jarvis Kaye, who has nearly 2 million subscribers on his YouTube channel, opened up to his fans in an emotional video post yesterday, November 3, in which he explained the events leading up to his ban.
The 17-year-old YouTuber revealed he had been uploading videos that showed him using aimbots in the game to improve the accuracy of his shooting, but said he was unaware that such actions would lead to a ban.
You can watch his emotional video below:
The use of aimbots, which are one of the most popular ways of cheating on Fortnite as they give players better aim and performance, are forbidden under the game’s rules – with cheaters risking having their account locked and deleted if they are caught using it.
It has also been reported some versions of the cheat software have even been found to contain dangerous malware that puts users at risk of having their private data stolen.
Kaye, a member of the FaZe Clan, explained in the video:
All I was thinking about whilst I was making those videos was just how entertaining and interesting these videos would be for you guys to watch.
It didn’t even cross my mind to think that I could be banned for life from Fortnite from those videos.
The 17-year-old broke down in tears as he explained he would never be able to play Fornite or create Fortnite-related content for his YouTube or Twitch channels ever again.
Kaye apologised to the game’s developers Epic Games and pleaded with them to reconsider his ban, saying he knows ‘how big of a mistake’ he has made, and is taking accountability for his actions. ‘I’m going to do my best to accept any punishment that comes my way,’ he added.
Kaye later took to Twitter to thank his followers for their continuous support, promising this wouldn’t be the end for him, while adding he would ‘never [have] thought about’ using the aimbot if he knew how ‘severe’ the consequences would be.
Epic Games are yet to respond to the gamer’s apology, although they maintain a zero tolerance policy on cheaters after acquiring security firm Kamu in 2018 to crack down on players in breach of its rules.
Some of the YouTuber’s fans have already voiced their support for KAye, starting the hashtag #FreeJarvis in an attempt to get Epic Games to change their mind.
A Broadcast Journalism Masters graduate who went on to achieve an NCTJ level 3 Diploma in Journalism, Lucy has done stints at ITV, BBC Inside Out and Key 103. While working as a journalist for UNILAD, Lucy has reported on breaking news stories while also writing features about mental health, cervical screening awareness, and Little Mix (who she is unapologetically obsessed with).

The study of lawyer films, even
unrealistic lawyer films, therefore can provide an important
supplement to the curriculum by teaching some important lessons.
The most important lesson is that justice counts. The very quantity
of 'law' films demonstrates that the human appetite for justice
is just as strong as our appetites for power and sex.

What Movies Teach Law Students
by John Denvir
We happily note that more and
more law schools are using films in their curriculum. For instance,
here at USF Law School, we are including extended discussions
of the film A Civil Action in our orientation program
for first year students. Now that the study of film has entered
the law school curriculum, perhaps it's time to ask exactly what
it adds to the student's educational experience that the traditional
curriculum lacks.
First,
I think we have to admit that films about lawyers do not give
a very accurate picture of how lawyers actually spend their days.
First of all, most of lawyer films feature trial lawyers while
most practicing lawyers seldom see a courtroom. Secondly, the
most common lawyer film, like To Kill a Mockingbird,
usually tells the story about the idealistic lawyer who represents
an innocent person falsely accused of crime. Practicing criminal
defense attorneys even admit that truly innocent defendants make
up a very small share of their clientele. And finally we also
must admit that movies and television take a great deal of artistic
license with procedural rules, thereby diluting any claim that
these fictions show students how law actually plays out in a
courtroom.
But even if we can't claim
verisimilitude for lawyer films and have to confess that lawyer
films tend to oversimplify messy reality in their pursuit of
a clear battle between good (idealistic lawyer) and evil (corrupt
system), I think we can still persuasively argue that the study
of movies provides an important antidote to the excessively
amoral "professional" model of lawyering that infects
the rest of the curriculum.
If the typical lawyer movie
highlights the human desire for a 'just' result with little
interest in procedural niceties, the professional model concerns
itself primarily with procedures. It assumes that procedural
justice will yield substantive justice, but this assumption ignores
the fact that when the legal resources needed to work the system
are not allocated on a basis even approaching equality, injustice
is often the result. Procedural justice might yield justice
in a society in which all citizens had equal access to the top-flight
lawyers, but this necessary condition is clearly not present
in even our most wealthy societies. For instance, in A Civil
Action, the plaintiffs fail in their suit against two large
companies who allegedly have dumped toxics into the town's drinking
water not because they had the lesser case in law and fact, but
because the defendants had the larger bankroll.
A second element of the professional model is related to this
procedural bias; it holds that we must put our faith in procedures
because there are simply no substantively 'right' answers"
in difficult cases, only arguments which favor plaintiff or defendant.
Convincing law students of the truth of the 'no truth' thesis
seems to be one of the major goals of the first year law school
curriculum. Students must abandon 'fuzzy' thinking and accept
that truth and justice are chimeras. Here's how one law student
put it:
"I made certain naïve emotional and political arguments
before law that I no longer buy into. Part of me feels, well,
there are certain things that are just right and wrong and then
there's another part of me that says, well, wait a minute, things
aren't that simple in the real world and you really can't go
around making silly emotional arguments about what's right and
wrong." 1
But the fact that the truth
is sometimes difficult to determine does not mean that there
is no truth, nor does it mean that all resolutions of a dispute
have a equal claim to the adjective 'just'. The primary goal
of a legal system should be to design systems that allow the
true facts to emerge in complicated situations.
Worse yet, students are led
to believe that their earlier faith in 'emotional arguments'
is a sign of intellectual immaturity and that adoption of the
value-free professional model is a form of personal progress.
I would suggest that (again to use the facts in A Civil Action
as an example) whether or not the defendant corporations polluted
the water that the plaintiffs drank is a factual question to
which a true answer can be found. And if true, the related question
of whether and how much compensation the plaintiffs should receive
from the defendant corporations is a question of justice as well
as law. And finally, acknowledging an emotional dimension to
the assignment of proper legal responsibility to the defendants
for their actions is a not a sign of intellectual immaturity;
instead it is evidence of a richer humanity.
A third element of the professional model is its definition
of "good" and "bad" lawyering solely in
terms of craft skills. Since law is a series of preset procedures
in which plaintiff and defendant wage a form of warfare, and
since there is no right answer to the issues they contest, a
good lawyer is not a hero who obtains justice, but rather an
expert who works the procedures to yield a result favorable to
his client. The professional model pictures lawyers operating
in a morally flattened universe in which craft values dominate.
Once again using A Civil Action as an example, the professional
model would argue that Jerome Facher (Robert Duvall) who keeps
relevant evidence hurtful to his client away from the jury is
the "good" lawyer. Perhaps we need to broaden our
definition of "good."
I don't want to be seen as
merely trashing the professional model; it has its virtues.
Law students need to learn how to think through problems methodically,
not just rushing to embrace emotionally appealing conclusions.
But I do think it gives an unduly amoral view of the lawyer's
role, one which unnecessarily subverts the idealism that brings
many students to choose law as a career in the first place.
The study of lawyer films,
even unrealistic lawyer films, therefore can provide an important
supplement to the curriculum by teaching some important lessons.
The most important lesson is that justice counts. The very quantity
of 'law' films demonstrates that the human appetite for justice
is just as strong as our appetites for power and sex.
Good lawyer films, like To King A Mockingbird and A
Civil Action, also teach a second important lesson: the practice
of law is fraught with ethical consequence. We can still debate
today whether Atticus Finch failed his client in submitting his
fate to a racist state court jury instead of seeking the aid
of the federal court. So too the ethical dilemmas facing Jan
Schlichtmann, the lawyer who represents the families harmed
by toxic water, are worthy of our deepest consideration. Schlichtmann
comes in with a simple goal-- to get as large fee as possible
with as little risk as possible. Yet slowly he discovers he wants
more; he wants to see justice done even though it's not exactly
clear what that concept means in this context. He finds himself
in a quandary. If he "takes the money and runs" as
he originally planned, he is no more than the "ambulance
chaser" the defense lawyers think him. But if he proceeds
with the case, he puts his clients, his partners, and himself
at financial risk. It's not easy for Schlichtmann or the viewer
to to balance these conflicting considerations, especially since
they don't calibrate on the same measure, but I think discussion
of a movie like A Civil Action can teach students that
the some of the most challenging parts of being a lawyer start
just where the professional model leaves off. 1. Quoted

and Beyond (New York: Routledge, 1992) 80.

Police treating London Bridge incident 'as though it's terror-related'
by The Associated Press Staff ContactLONDON -- London’s Metropolitan Police say that though the circumstances of an incident on London Bridge remain unclear, authorities are treating it as if it is terror-related.
The police acknowledged one man had been shot in the incident that began at 1:58 p.m. on Friday. The police say that “at this stage, the circumstances relating to the incident at #LondonBridge remain unclear. However, as a precaution, we are currently responding to this incident as though it is terror-related.”
“One man has been shot by police. We will provide further information when possible.”
They previously said that several people had been stabbed nearby.

Ever wondered what conditionals are? Let's dive in to understand a fancy term given for what you already know.
Conditionals statements are features in computer science that your program decides to select. It's the same as selection conditions that you've been using in daily life.
For instance, there is an ice-cream truck in a park. What's the first question that comes to your mind? Do I want an ice-cream? If you feel like having one, you will ask your parents to buy you one or you will decide may be next time. By setting two conditions--Want an ice-cream or not--you just used the if-else conditional statement. Now, if you decide to have an ice-cream, you will have to use selection conditions again. What flavor do you want? If vanilla you have to pay $1.99, else if strawberry pay $0.99, else if vanilla with chocolate chip then pay $3.99, and so on.
Now, for computers to use similar workflow, programming languages--languages that are used to communicate with computer--use different types of conditional statements. For example, if, if else, switch, else if, et cetera. For now, let's play a quick game.
Suppose, There is a runaway trolley barreling down the railway tracks. Ahead, on the tracks, there are five people tied up and unable to move. The trolley is headed straight for them.  What are the different selection situations that you can think of?


Equithon is being held in two buildings at the University of Waterloo, one of which was named after a prominent figure in mobile phone technology. The next clue is 'his first name' + 'the company he founded'.


Market Update
Bitcoin Price Analyst: ‘Second Phase’ of Bull Market Triggers at $14K
by William SubergBitcoin (BTC) was trending higher on Nov. 4 as sideways behavior gave way to more purposeful upward momentum across markets.

Bitcoin seeks to break out of trading range
Data from Coin360 reveals BTC/USD tackling $9,300 on Monday, rising to a 24-hour high of $9,310 on exchanges after dipping as low as $9,080.
The latest action continues the weekly trend for Bitcoin, which has seen the largest cryptocurrency range between just under $9,000 and just over $9,500. Those levels effectively formed support and resistance, respectively.

Now, analysts are turning their attention to the required conditions for a more purposeful breakout — either up or down.
Willy Woo: CME gap likely to be filled
According to statistician Willy Woo, the coming few months for Bitcoin will first see a dip to $8,600, filling in a gap in futures markets.
Thereafter, bullish action should begin to surface. Bitcoin needs a monthly close above $14,000 in order to then secure a longer-term bull market.
“Once we get a monthly close above $14k, we'll be in the second phase of the bull market; a steady, lowish volatility, run in price. Should happen by the start of 2020, that's the best time to deploy capital,” he summarized in a series of tweets on Monday.
As Cointelegraph reported, Woo is not alone in forecasting a short-term slide for BTC/USD. Last week, regular contributor filbfilb also eyed the potential for the pair to revisit the $8,000 bracket.
In an update on his dedicated Telegram trading channel on Sunday, he continued the narrative:
“Suspect there are a lot of over leveraged people in the 9300s with stops below 9k. Whales probably tempted to dump it and get a lower entry.”
Altcoin markets see green
Altcoins meanwhile took the chance to deliver moderate gains in line with Bitcoin’s slight uptick.
Out of the top twenty cryptocurrencies by market cap, many rose by up to 4% on the day, with only Bitcoin SV (BSV) seeing losses of 1.6%.
Ether (ETH), the largest altcoin, saw gains of 1.7% to trade $184. Both NEO (NEO) and Litecoin (LTC) performed strongly, with 4.5% advances.

The overall cryptocurrency market cap was $247 billion at press time, with Bitcoin’s share at 67.3%.

Webcardinal is designed to offer full two-way binding support for the native HTML form elements.
The two-way binding mechanism of WebCardinal may offer limited support when using PrivateSky form

The Jepson Flora Project brings together all of the floristic references and data of the Jepson Herbarium. Resources of the Flora Project are directly linked to the Consortium of California Herbaria, CalPhotos, the California Native Plant Society, California Exotic Pest Plant Council, USDA-Plants database, and many other external sites. The
Friends of the Jepson Herbarium
help the Jepson Flora project carry out its work.
Visit our staff page for more information about our editorial board and staff.
The online component of the Jepson Flora Project, provides users with a single interface from which they can find the most comprehensive, scientifically accurate sources of information on the California flora.
Click on the "Read more" links below to learn more about each resource.

The Jepson eFlora contains taxonomic treatments for native and naturalized plants occurring in wildlands or otherwise outside of cultivation in California. Documented waifs and some agricultural weeds are also included. Treatments were initially derived from the second edition of The Jepson Manual: Vascular Plants of California (2012).
The eFlora has diverged from the print book in that it:
(1) contains descriptions not in the print book (e.g., waifs, agricultural weeds);
(2) contains errata and other changes made relative to the print book;
(3) contains direct links to the Consortium of California Herbaria;
(4) contains direct links to the Online Interchange for California Floristics; and
(5) contains substantive revisions of scientific content for some taxa; see Supplement 1, July 2013.

|
|
|
|
The second edition of The Jepson Manual: Vascular Plants of California (TJM2) was published in 2012 and treats the nearly 8,000 vascular plant taxa native or naturalized in California. Since its publication, some treatments have been revised. Updates are available via the Jepson eFlora.
Find links to additional publications of the Jepson Herbarium at http://ucjeps.berkeley.edu/Herb_Pubs.html.
Errata and other small changes for TJM2 are at http://ucjeps.berkeley.edu/JM12_errata.html.

A Flora of California was published by the Jepson Herbarium in a multi-volume series beginning in 1909 and continuing steadily through 1940. Work on the Flora slowed after Jepson's death in 1946, with Volume 4 Part 2 by Lauramay T. Dempster, appearing in 1979 after a long hiatus. The Flora contains exceptionally detailed taxonomic treatments and comprehensive description of morphological characteristics, habitats, and ecology and original line drawings for many taxa in California. Unfortunately, this great work is now out-of-print, although there are a limited number of full sets still available through the Jepson Herbarium.
The Flora can be accessed electronically via an index which includes ~12,000 accepted names and synonyms. It is also part of the Biodiversity Heritage Library (http://www.biodiversitylibrary.org/bibliography/7604#/summary)

Javascript is quite different to HTML and CSS. HTML provides the content and structure, CSS provides styling and Javascript powers the interactive parts of a website. For example, Javascript could be used for a block of rotating images, or for a menu that pops up when clicked.
Control flow is the order in which instructions in code execute. Loops are a way to manipulate control flow, according to variables. Two important types of control flow are if/if else statements, and for loops. If statements show a series of choices, and how to respond if a choice is made. For loops give information about when to start and end actions. For example: Reading. FOR(start reading at page zero; read until you are bored) IF (you see an interesting quote) {write it down} ELSE IF (you don't like this book) {tear out the page}. Control flow is a means for a computer to decide how to respond to a variety of different user choices.
Object literals and arrays are both ways of holding collections of data. Data inside an array is contained in square brackets. Each piece of data has an assigned number, referring to its position inside the array. The numbering starts at zero, so the first piece of data would be at the index zero. You can access this data with arrayName[0].
An object literal is contained inside curly brackets. The data inside is expressed in pairs of properties and values. For example, for an object myDog, a property could be 'Name' and value could be 'Tommy' (which is his name). Objects don't use assigned numbers to access pieces of data inside. Instead we could use either myDog.name or myDog["name"] to access properties. Objects can also have functions asigned to them, which makes them a useful way to hold data.
A function is a block of code that executes some kind of task. They are the way you make your website interactive. They are very useful for tasks that you will need to use multiple times throughout your code, because instead of rewriting the command every time you need it, you can just call the function.
