The White Lotus Season 1 Episode 1
Work of art in the form of a Movie of live images that are rotated to produce an illusion of moving images that are presented as a form of entertainment. The illusion of a Movie of images produces continuous motion in the form of video. The film is often referred to as a Movie or moving picture. Film is a modern and popular art form created for business and entertainment purposes. Film making has now become a popular The White Lotus Season 1 Episode 1 Season throughout the world, where feature films are always awaited by cinemas. Films are made in two main ways. The first is through shooting and recording techniques through film cameras. This method is done by photographing images or objects. The second uses traditional animation techniques. This method is done through computer graphic animation or CGI techniques. Both can also be combined with other techniques and visual effects. Filming usually takes a relatively long time. It also requires a job desk each, starting from the director, producer, editor, wardrobe, visual effects and others. Definition and Definition of Film / Movie While the players who play a role in the film are referred to as actors (men) or actresses (women). There is also the term extras that are used as supporting characters with few roles in the film. This is different from the main actors who have bigger and more roles. Being an actor and an actress must be demanded to have good acting talent, which is in accordance with the theme of the film he is starring in. In certain scenes, the actor’s role can be replaced by a stuntman or a stuntman. The existence of a stuntman is important to replace the actors doing scenes that are difficult and extreme, which are usually found in action action films. Films can also be used to convey certain messages from the filmmaker. Some industries also use film to convey and represent their symbols and culture. Filmmaking is also a form of expression, thoughts, ideas, concepts, feelings and moods of a human being visualized in film. The film itself is mostly a fiction, although some are based on fact true stories or based on a true story. There are also documentaries with original and real pictures, or biographical films that tell the story of a character. There are many other popular genre films, ranging from action films, horror films, comedy films, romantic films, fantasy films, thriller films, drama films, science fiction films, crime films, documentaries and others. That’s a little information about the definition of film or Movie. The information was quoted from various sources and references. Hope it can be useful.
??? TV Movie ???
The first television shows were experimental, sporadic broadcasts viewable only within a very short range from the broadcast tower starting in the 1930s. Televised events such as the 1936 Summer Olympics in Germany, the 1939 coronation of King George VI in the UK, and David Sarnoff’s famous introduction at the 1939 New York World’s Fair in the US spurred a growth in the medium, but World War II put a halt to development until after the war. The 19440 World Movie inspired many Americans to buy their first television set and then in 1948, the popular radio show Texaco Star Theater made the move and became the first weekly televised variety show, earning host Milton Berle the name “Mr Television” and demonstrating that the medium was a stable, modern form of entertainment which could attract advertisers. The first national live television broadcast in the US took place on September 4, 1941 when President Harry Truman’s speech at the Japanese Peace Treaty Conference in San FraThe White Lotus Season 1 Episode 1 Seasonco was transmitted over AT&T’s transcontinental cable and microwave radio relay system to broadcast stations in local markets. The first national color broadcast (the 1984 Tournament of Roses Parade) in the US occurred on January 1, 1984. During the following ten years most network broadcasts, and nearly all local programming, continued to be in black-and-white. A color transition was announced for the fall of 1965, during which over half of all network prime-time programming would be broadcast in color. The first all-color prime-time season came just one year later. In 19402, the last holdout among daytime network shows converted to color, resulting in the first completely all-color network season.
??? Formats and Genres ???
See also: List of genres § Film and television formats and genres Television shows are more varied than most other forms of media due to the wide variety of formats and genres that can be presented. A show may be fictional (as in comedies and dramas), or non-fictional (as in documentary, news, and reality television). It may be topical (as in the case of a local newscast and some made-for-television films), or historical (as in the case of many documentaries and fictional Movie). They could be primarily instructional or educational, or entertaining as is the case in situation comedy and game shows.[citation needed] A drama program usually features a set of actors playing characters in a historical or contemporary setting. The program follows their lives and adventures. Before the 1980s, shows (except for soap opera-type serials) typically remained static without story arcs, and the main characters and premise changed little.[citation needed] If some change happened to the characters’ lives during the episode, it was usually undone by the end. Because of this, the Movie could be broadcast in any order.[citation needed] Since the 1980s, many Movie feature progressive change in the plot, the characters, or both. For instance, Hill Street Blues and St. Elsewhere were two of the first American prime time drama television Movie to have this kind of dramatic structure,[4][better source needed] while the later Movie Babylon 5 further exemplifies such structure in that it had a predetermined story running over its intended five-season run.[citation needed] In “DC1&”, it was reported that television was growing into a larger component of major media companies’ revenues than film. Some also noted the increase in quality of some television programs. In “DC1&”, Academy-Award-winning film director Steven Soderbergh, commenting on ambiguity and complexity of character and narrative, stated: “I think those qualities are now being seen on television and that people who want to see stories that have those kinds of qualities are watching television.

STREAMING MEDIA
Streaming media is multimedia that is constantly received by and presented to an end-user while being delivered by a provider. The verb to stream refers to the process of delivering or obtaining media in this manner.clarification needed Streaming refers to the delivery method of the medium, rather than the medium itself. Distinguishing delivery method from the media distributed applies specifically to telecommunications networks, as most of the delivery systems are either inherently streaming (e.g. radio, television, streaming apps) or inherently non-streaming (e.g. books, video cassettes, audio CDs). There are challenges with streaming content on the Internet. For example, users whose Internet connection lacks sufficient bandwidth may experience stops, lags, or slow buffering of the content. And users lacking compatible hardware or software systems may be unable to stream certain content.
Live streaming is the delivery of Internet content in real-time much as live television broadcasts content over the airwaves via a television signal. Live internet streaming requires a form of source media (e.g. a video camera, an audio interface, screen capture software), an encoder to digitize the content, Do you remember when YouTube wasn’t the YouTube you know today==> In 2003, when Steve Chen, Chad Hurley, and Jawed Karim activated the domain youtube they had a vision.a media publisher, and a content delivery network to distribute and deliver the content. Live streaming does not need to be recorded at the origination point, although it frequently is.
Streaming is an alternative to file downloading, a process in which the end-user obtains the entire file for the content before watching or listening to it. Through streaming, an end-user can use their media player to start playing digital video or digital audio content before the entire file has been transmitted. The term streaming media can apply to media other than video and audio, such as live closed captioning, ticker tape, and real-time text, which are all considered streaming text.
COPYRIGHT CONTENT
Copyright is a type of intellectual property that gives its owner the exclusive right to make copies of a creative work, usually for a limited time.12344 The creative work may be in a literary, artistic, educational, or musical form. Copyright is intended to protect the original expression of an idea in the form of a creative work, but not the idea itself.678 A copyright is subject to limitations based on public interest considerations, such as the fair use doctrine in the United States.
Some jurisdictions require fixing copyrighted works in a tangible form. It is often shared among multiple authors, each of whom holds a set of rights to use or license the work, and who are commonly referred to as rights holders.citation needed 2021 These rights frequently include reproduction, control over derivative works, distribution, public performance, and moral rights such as attribution.13
Copyrights can be granted by public law and are in that case considered territorial rights. This means that copyrights granted by the law of a certain state, do not extend beyond the territory of that specific jurisdiction. Copyrights of this type vary by country; many countries, and sometimes a large group of countries, have made agreements with other countries on procedures applicable when works cross national borders or national rights are inconsistent.14
Typically, the public law duration of a copyright expires 10 to 100 years after the creator dies, depending on the jurisdiction. Some countries require certain copyright formalities4 to establishing copyright, others recognize copyright in any completed work, without a formal registration.
It is widely believed that copyrights are a must to foster cultural diversity and creativity. However, Parc argues that contrary to prevailing beliefs, imitation and copying do not restrict cultural creativity or diversity but in fact support them further. This argument has been supported by many examples such as Millet and Van Gogh, Picasso, Manet, and Monet, etc.
GOODS OF SERVICES
Credit (from Latin credit) is the trust which allows one party to provide money or resources to another party wherein the second party does not reimburse the first party immediately (thereby generating a debt), but promises either to repay or return those resources (or other materials of equal value) at a later date.1 In other words, credit is a method of making reciprocity formal, legally enforceable, and extensible to a large group of unrelated people.
The resources provided may be financial ( granting a loan), or they may consist of goods or services (consumer credit). Credit encompasses any form of deferred payment.10 Credit is extended by a creditor, also known as a lender, to a debtor, also known as a borrower.
A television show might also be called a television program (British English programme), especially if it lacks a narrative structure. A television series is usually released in episodes that follow a narrative, and are usually divided into seasons (US and Canada) or series (UK) — yearly or semiannual sets of new episodes. A show with a limited number of episodes may be called a miniseries, serial, or limited series. A one-time show may be called a special. A television film (made-for-TV movie or television movie ) is a film that is initially broadcast on television rather than released in theaters or direct-to-video.
Television shows can be viewed as they are broadcast in real time (live), be recorded on home video or a digital video recorder for later viewing, or be viewed on demand via a set-top box or streamed over the internet."

A Pure PHP Implementation Of The MessagePack Serialization Format
msgpack.php
A pure PHP implementation of the MessagePack serialization format.
Features
- Fully compliant with the latest MessagePack specification
- Supports streaming unpacking
- Supports unsigned 64-bit integers handling
- Supports object serialization
- Fully tested
- Relatively fast
Installation
The recommended way to install the library is through Composer:
composer require rybakit/msgpack
Usage
Packing
To pack values you can either use an instance of a Packer:
$packer = new Packer();
$packed = $packer->pack($value);
or call a static method on the MessagePack class:
$packed = MessagePack::pack($value);
In the examples above, the method pack automatically packs a value depending on its type. However, not all PHP types can be uniquely translated to MessagePack types. For example, the MessagePack format defines map and array types, which are represented by a single array type in PHP. By default, the packer will pack a PHP array as a MessagePack array if it has sequential numeric keys, starting from 0 and as a MessagePack map otherwise:
$mpArr1 = $packer->pack([1, 2]); // MP array [1, 2]
$mpArr2 = $packer->pack([0 => 1, 1 => 2]); // MP array [1, 2]
$mpMap1 = $packer->pack([0 => 1, 2 => 3]); // MP map {0: 1, 2: 3}
$mpMap2 = $packer->pack([1 => 2, 2 => 3]); // MP map {1: 2, 2: 3}
$mpMap3 = $packer->pack(['a' => 1, 'b' => 2]); // MP map {a: 1, b: 2}
However, sometimes you need to pack a sequential array as a MessagePack map. To do this, use the packMap method:
$mpMap = $packer->packMap([1, 2]); // {0: 1, 1: 2}
Here is a list of type-specific packing methods:
$packer->packNil(); // MP nil
$packer->packBool(true); // MP bool
$packer->packInt(42); // MP int
$packer->packFloat(M_PI); // MP float (32 or 64)
$packer->packFloat32(M_PI); // MP float 32
$packer->packFloat64(M_PI); // MP float 64
$packer->packStr('foo'); // MP str
$packer->packBin("\x80"); // MP bin
$packer->packArray([1, 2]); // MP array
$packer->packMap(['a' => 1]); // MP map
$packer->packExt(1, "\xaa"); // MP ext
Check the "Custom types" section below on how to pack custom types.
Packing options
The Packer object supports a number of bitmask-based options for fine-tuning the packing process (defaults are in bold):
| Name | Description |
|---|---|
FORCE_STR | Forces PHP strings to be packed as MessagePack UTF-8 strings |
FORCE_BIN | Forces PHP strings to be packed as MessagePack binary data |
DETECT_STR_BIN | Detects MessagePack str/bin type automatically |
FORCE_ARR | Forces PHP arrays to be packed as MessagePack arrays |
FORCE_MAP | Forces PHP arrays to be packed as MessagePack maps |
DETECT_ARR_MAP | Detects MessagePack array/map type automatically |
FORCE_FLOAT32 | Forces PHP floats to be packed as 32-bits MessagePack floats |
FORCE_FLOAT64 | Forces PHP floats to be packed as 64-bits MessagePack floats |
The type detection mode (
DETECT_STR_BIN/DETECT_ARR_MAP) adds some overhead which can be noticed when you pack large (16- and 32-bit) arrays or strings. However, if you know the value type in advance (for example, you only work with UTF-8 strings or/and associative arrays), you can eliminate this overhead by forcing the packer to use the appropriate type, which will save it from running the auto-detection routine. Another option is to explicitly specify the value type. The library provides 2 auxiliary classes for this,MapandBin. Check the "Custom types" section below for details.
Examples:
// detect str/bin type and pack PHP 64-bit floats (doubles) to MP 32-bit floats
$packer = new Packer(PackOptions::DETECT_STR_BIN | PackOptions::FORCE_FLOAT32);
// these will throw MessagePack\Exception\InvalidOptionException
$packer = new Packer(PackOptions::FORCE_STR | PackOptions::FORCE_BIN);
$packer = new Packer(PackOptions::FORCE_FLOAT32 | PackOptions::FORCE_FLOAT64);
Unpacking
To unpack data you can either use an instance of a BufferUnpacker:
$unpacker = new BufferUnpacker();
$unpacker->reset($packed);
$value = $unpacker->unpack();
or call a static method on the MessagePack class:
$value = MessagePack::unpack($packed);
If the packed data is received in chunks (e.g. when reading from a stream), use the tryUnpack method, which attempts to unpack data and returns an array of unpacked messages (if any) instead of throwing an InsufficientDataException:
while ($chunk = ...) {
$unpacker->append($chunk);
if ($messages = $unpacker->tryUnpack()) {
return $messages;
}
}
If you want to unpack from a specific position in a buffer, use seek:
$unpacker->seek(42); // set position equal to 42 bytes
$unpacker->seek(-8); // set position to 8 bytes before the end of the buffer
To skip bytes from the current position, use skip:
$unpacker->skip(10); // set position to 10 bytes ahead of the current position
To get the number of remaining (unread) bytes in the buffer:
$unreadBytesCount = $unpacker->getRemainingCount();
To check whether the buffer has unread data:
$hasUnreadBytes = $unpacker->hasRemaining();
If needed, you can remove already read data from the buffer by calling:
$releasedBytesCount = $unpacker->release();
With the read method you can read raw (packed) data:
$packedData = $unpacker->read(2); // read 2 bytes
Besides the above methods BufferUnpacker provides type-specific unpacking methods, namely:
$unpacker->unpackNil(); // PHP null
$unpacker->unpackBool(); // PHP bool
$unpacker->unpackInt(); // PHP int
$unpacker->unpackFloat(); // PHP float
$unpacker->unpackStr(); // PHP UTF-8 string
$unpacker->unpackBin(); // PHP binary string
$unpacker->unpackArray(); // PHP sequential array
$unpacker->unpackMap(); // PHP associative array
$unpacker->unpackExt(); // PHP MessagePack\Type\Ext object
Unpacking options
The BufferUnpacker object supports a number of bitmask-based options for fine-tuning the unpacking process (defaults are in bold):
| Name | Description |
|---|---|
BIGINT_AS_STR | Converts overflowed integers to strings [1] |
BIGINT_AS_GMP | Converts overflowed integers to GMP objects [2] |
BIGINT_AS_DEC | Converts overflowed integers to Decimal\Decimal objects [3] |
1. The binary MessagePack format has unsigned 64-bit as its largest integer data type, but PHP does not support such integers, which means that an overflow can occur during unpacking.
2. Make sure the GMP extension is enabled.
3. Make sure the Decimal extension is enabled.
Examples:
$packedUint64 = "\xcf"."\xff\xff\xff\xff"."\xff\xff\xff\xff";
$unpacker = new BufferUnpacker($packedUint64);
var_dump($unpacker->unpack()); // string(20) "18446744073709551615"
$unpacker = new BufferUnpacker($packedUint64, UnpackOptions::BIGINT_AS_GMP);
var_dump($unpacker->unpack()); // object(GMP) {...}
$unpacker = new BufferUnpacker($packedUint64, UnpackOptions::BIGINT_AS_DEC);
var_dump($unpacker->unpack()); // object(Decimal\Decimal) {...}
Custom types
In addition to the basic types, the library provides functionality to serialize and deserialize arbitrary types. This can be done in several ways, depending on your use case. Let's take a look at them.
Type objects
If you need to serialize an instance of one of your classes into one of the basic MessagePack types, the best way to do this is to implement the CanBePacked interface in the class. A good example of such a class is the Map type class that comes with the library. This type is useful when you want to explicitly specify that a given PHP array should be packed as a MessagePack map without triggering an automatic type detection routine:
$packer = new Packer();
$packedMap = $packer->pack(new Map([1, 2, 3]));
$packedArray = $packer->pack([1, 2, 3]);
More type examples can be found in the src/Type directory.
Type transformers
As with type objects, type transformers are only responsible for serializing values. They should be used when you need to serialize a value that does not implement the CanBePacked interface. Examples of such values could be instances of built-in or third-party classes that you don't own, or non-objects such as resources.
A transformer class must implement the CanPack interface. To use a transformer, it must first be registered in the packer. Here is an example of how to serialize PHP streams into the MessagePack bin format type using one of the supplied transformers, StreamTransformer:
$packer = new Packer(null, [new StreamTransformer()]);
$packedBin = $packer->pack(fopen('/path/to/file', 'r+'));
More type transformer examples can be found in the src/TypeTransformer directory.
Extensions
In contrast to the cases described above, extensions are intended to handle extension types and are responsible for both serialization and deserialization of values (types).
An extension class must implement the Extension interface. To use an extension, it must first be registered in the packer and the unpacker.
The MessagePack specification divides extension types into two groups: predefined and application-specific. Currently, there is only one predefined type in the specification, Timestamp.
Timestamp
The Timestamp extension type is a predefined type. Support for this type in the library is done through the TimestampExtension class. This class is responsible for handling Timestamp objects, which represent the number of seconds and optional adjustment in nanoseconds:
$timestampExtension = new TimestampExtension();
$packer = new Packer();
$packer = $packer->extendWith($timestampExtension);
$unpacker = new BufferUnpacker();
$unpacker = $unpacker->extendWith($timestampExtension);
$packedTimestamp = $packer->pack(Timestamp::now());
$timestamp = $unpacker->reset($packedTimestamp)->unpack();
$seconds = $timestamp->getSeconds();
$nanoseconds = $timestamp->getNanoseconds();
When using the MessagePack class, the Timestamp extension is already registered:
$packedTimestamp = MessagePack::pack(Timestamp::now());
$timestamp = MessagePack::unpack($packedTimestamp);
Application-specific extensions
In addition, the format can be extended with your own types. For example, to make the built-in PHP DateTime objects first-class citizens in your code, you can create a corresponding extension, as shown in the example. Please note, that custom extensions have to be registered with a unique extension ID (an integer from 0 to 127).
More extension examples can be found in the examples/MessagePack directory.
To learn more about how extension types can be useful, check out this article.
Exceptions
If an error occurs during packing/unpacking, a PackingFailedException or an UnpackingFailedException will be thrown, respectively. In addition, an InsufficientDataException can be thrown during unpacking.
An InvalidOptionException will be thrown in case an invalid option (or a combination of mutually exclusive options) is used.
Tests
Run tests as follows:
vendor/bin/phpunit
Also, if you already have Docker installed, you can run the tests in a docker container. First, create a container:
./dockerfile.sh | docker build -t msgpack -
The command above will create a container named msgpack with PHP 8.1 runtime. You may change the default runtime by defining the PHP_IMAGE environment variable:
PHP_IMAGE='php:8.0-cli' ./dockerfile.sh | docker build -t msgpack -
See a list of various images here.
Then run the unit tests:
docker run --rm -v $PWD:/msgpack -w /msgpack msgpack
Fuzzing
To ensure that the unpacking works correctly with malformed/semi-malformed data, you can use a testing technique called Fuzzing. The library ships with a help file (target) for PHP-Fuzzer and can be used as follows:
php-fuzzer fuzz tests/fuzz_buffer_unpacker.php
Performance
To check performance, run:
php -n -dzend_extension=opcache.so \
-dpcre.jit=1 -dopcache.enable=1 -dopcache.enable_cli=1 \
tests/bench.php

You may change default benchmark settings by defining the following environment variables:
| Name | Default |
|---|---|
| MP_BENCH_TARGETS | pure_p,pure_u, see a list of available targets |
| MP_BENCH_ITERATIONS | 100_000 |
| MP_BENCH_DURATION | not set |
| MP_BENCH_ROUNDS | 3 |
| MP_BENCH_TESTS | -@slow, see a list of available tests |
For example:
export MP_BENCH_TARGETS=pure_p
export MP_BENCH_ITERATIONS=1000000
export MP_BENCH_ROUNDS=5
# a comma separated list of test names
export MP_BENCH_TESTS='complex array, complex map'
# or a group name
# export MP_BENCH_TESTS='-@slow' // @pecl_comp
# or a regexp
# export MP_BENCH_TESTS='/complex (array|map)/'

Treebender: A Symbolic Natural Language Parsing Library for Rust
Treebender
A symbolic natural language parsing library for Rust, inspired by HDPSG.
What is this?
This is a library for parsing natural or constructed languages into syntax trees and feature structures. There's no machine learning or probabilistic models, everything is hand-crafted and deterministic.
You can find out more about the motivations of this project in this blog post.
But what are you using it for?
I'm using this to parse a constructed language for my upcoming xenolinguistics game, Themengi.
Motivation
Using a simple 80-line grammar, introduced in the tutorial below, we can parse a simple subset of English, checking reflexive pronoun binding, case, and number agreement.
$ cargo run --bin cli examples/reflexives.fgr
> she likes himself
Parsed 0 trees
> her likes herself
Parsed 0 trees
> she like herself
Parsed 0 trees
> she likes herself
Parsed 1 tree
(0..3: S
(0..1: N (0..1: she))
(1..2: TV (1..2: likes))
(2..3: N (2..3: herself)))
[
child-2: [
case: acc
pron: ref
needs_pron: #0 she
num: sg
child-0: [ word: herself ]
]
child-1: [
tense: nonpast
child-0: [ word: likes ]
num: #1 sg
]
child-0: [
child-0: [ word: she ]
case: nom
pron: #0
num: #1
]
]
Low resource language? Low problem! No need to train on gigabytes of text, just write a grammar using your brain. Let's hypothesize that in American Sign Language, topicalized nouns (expressed with raised eyebrows) must appear first in the sentence. We can write a small grammar (18 lines), and plug in some sentences:
$ cargo run --bin cli examples/asl-wordorder.fgr -n
> boy sit
Parsed 1 tree
(0..2: S
(0..1: NP ((0..1: N (0..1: boy))))
(1..2: IV (1..2: sit)))
> boy throw ball
Parsed 1 tree
(0..3: S
(0..1: NP ((0..1: N (0..1: boy))))
(1..2: TV (1..2: throw))
(2..3: NP ((2..3: N (2..3: ball)))))
> ball nm-raised-eyebrows boy throw
Parsed 1 tree
(0..4: S
(0..2: NP
(0..1: N (0..1: ball))
(1..2: Topic (1..2: nm-raised-eyebrows)))
(2..3: NP ((2..3: N (2..3: boy))))
(3..4: TV (3..4: throw)))
> boy throw ball nm-raised-eyebrows
Parsed 0 trees
Tutorial
As an example, let's say we want to build a parser for English reflexive pronouns (himself, herself, themselves, themself, itself). We'll also support number ("He likes X" v.s. "They like X") and simple embedded clauses ("He said that they like X").
Grammar files are written in a custom language, similar to BNF, called Feature GRammar (.fgr). There's a VSCode syntax highlighting extension for these files available as fgr-syntax.
We'll start by defining our lexicon. The lexicon is the set of terminal symbols (symbols in the actual input) that the grammar will match. Terminal symbols must start with a lowercase letter, and non-terminal symbols must start with an uppercase letter.
// pronouns
N -> he
N -> him
N -> himself
N -> she
N -> her
N -> herself
N -> they
N -> them
N -> themselves
N -> themself
// names, lowercase as they are terminals
N -> mary
N -> sue
N -> takeshi
N -> robert
// complementizer
Comp -> that
// verbs -- intransitive, transitive, and clausal
IV -> falls
IV -> fall
IV -> fell
TV -> likes
TV -> like
TV -> liked
CV -> says
CV -> say
CV -> said
Next, we can add our sentence rules (they must be added at the top, as the first rule in the file is assumed to be the top-level rule):
// sentence rules
S -> N IV
S -> N TV N
S -> N CV Comp S
// ... previous lexicon ...
Assuming this file is saved as examples/no-features.fgr (which it is :wink:), we can test this file with the built-in CLI:
$ cargo run --bin cli examples/no-features.fgr
> he falls
Parsed 1 tree
(0..2: S
(0..1: N (0..1: he))
(1..2: IV (1..2: falls)))
[

child-0: [ child-0: [ word: he ] ]

child-1: [ child-0: [ word: likes ] ]
child-0: [ child-0: [ word: he ] ]
]

Parsed 1 tree

(2..3: Comp (2..3: that))
(3..6: S
(3..4: N (3..4: he))
(4..5: TV (4..5: likes))
(5..6: N (5..6: her))))
[
child-0: [ child-0: [ word: he ] ]
child-2: [ child-0: [ word: that ] ]
child-1: [ child-0: [ word: said ] ]
child-3: [
child-2: [ child-0: [ word: her ] ]
child-1: [ child-0: [ word: likes ] ]
child-0: [ child-0: [ word: he ] ]
]
]
> he said that he
Parsed 0 trees
This grammar already parses some correct sentences, and blocks some trivially incorrect ones. However, it doesn't care about number, case, or reflexives right now:
> she likes himself // unbound reflexive pronoun
Parsed 1 tree
(0..3: S
(0..1: N (0..1: she))
(1..2: TV (1..2: likes))
(2..3: N (2..3: himself)))
[
child-0: [ child-0: [ word: she ] ]
child-2: [ child-0: [ word: himself ] ]
child-1: [ child-0: [ word: likes ] ]
]
> him like her // incorrect case on the subject pronoun, should be nominative
// (he) instead of accusative (him)
Parsed 1 tree
(0..3: S
(0..1: N (0..1: him))
(1..2: TV (1..2: like))
(2..3: N (2..3: her)))
[
child-0: [ child-0: [ word: him ] ]
child-1: [ child-0: [ word: like ] ]
child-2: [ child-0: [ word: her ] ]
]
> he like her // incorrect verb number agreement
Parsed 1 tree
(0..3: S
(0..1: N (0..1: he))
(1..2: TV (1..2: like))
(2..3: N (2..3: her)))
[
child-2: [ child-0: [ word: her ] ]
child-1: [ child-0: [ word: like ] ]
child-0: [ child-0: [ word: he ] ]
]
To fix this, we need to add features to our lexicon, and restrict the sentence rules based on features.
Features are added with square brackets, and are key: value pairs separated by commas. **top** is a special feature value, which basically means "unspecified" -- we'll come back to it later. Features that are unspecified are also assumed to have a **top** value, but sometimes explicitly stating top is more clear.
/// Pronouns
// The added features are:
// * num: sg or pl, whether this noun wants a singular verb (likes) or
// a plural verb (like). note this is grammatical number, so for example
// singular they takes plural agreement ("they like X", not *"they likes X")
// * case: nom or acc, whether this noun is nominative or accusative case.
// nominative case goes in the subject, and accusative in the object.
// e.g., "he fell" and "she likes him", not *"him fell" and *"her likes he"
// * pron: he, she, they, or ref -- what type of pronoun this is
// * needs_pron: whether this is a reflexive that needs to bind to another
// pronoun.
N[ num: sg, case: nom, pron: he ] -> he
N[ num: sg, case: acc, pron: he ] -> him
N[ num: sg, case: acc, pron: ref, needs_pron: he ] -> himself
N[ num: sg, case: nom, pron: she ] -> she
N[ num: sg, case: acc, pron: she ] -> her
N[ num: sg, case: acc, pron: ref, needs_pron: she] -> herself
N[ num: pl, case: nom, pron: they ] -> they
N[ num: pl, case: acc, pron: they ] -> them
N[ num: pl, case: acc, pron: ref, needs_pron: they ] -> themselves
N[ num: sg, case: acc, pron: ref, needs_pron: they ] -> themself
// Names
// The added features are:
// * num: sg, as people are singular ("mary likes her" / *"mary like her")
// * case: **top**, as names can be both subjects and objects
// ("mary likes her" / "she likes mary")
// * pron: whichever pronoun the person uses for reflexive agreement
// mary pron: she => mary likes herself
// sue pron: they => sue likes themself
// takeshi pron: he => takeshi likes himself
N[ num: sg, case: **top**, pron: she ] -> mary
N[ num: sg, case: **top**, pron: they ] -> sue
N[ num: sg, case: **top**, pron: he ] -> takeshi
N[ num: sg, case: **top**, pron: he ] -> robert
// Complementizer doesn't need features
Comp -> that
// Verbs -- intransitive, transitive, and clausal
// The added features are:
// * num: sg, pl, or **top** -- to match the noun numbers.
// **top** will match either sg or pl, as past-tense verbs in English
// don't agree in number: "he fell" and "they fell" are both fine
// * tense: past or nonpast -- this won't be used for agreement, but will be
// copied into the final feature structure, and the client code could do
// something with it
IV[ num: sg, tense: nonpast ] -> falls
IV[ num: pl, tense: nonpast ] -> fall
IV[ num: **top**, tense: past ] -> fell
TV[ num: sg, tense: nonpast ] -> likes
TV[ num: pl, tense: nonpast ] -> like
TV[ num: **top**, tense: past ] -> liked
CV[ num: sg, tense: nonpast ] -> says
CV[ num: pl, tense: nonpast ] -> say
CV[ num: **top**, tense: past ] -> said
Now that our lexicon is updated with features, we can update our sentence rules to constrain parsing based on those features. This uses two new features, tags and unification. Tags allow features to be associated between nodes in a rule, and unification controls how those features are compatible. The rules for unification are:
- A string feature can unify with a string feature with the same value
- A top feature can unify with anything, and the nodes are merged
- A complex feature ([ ... ] structure) is recursively unified with another complex feature.
If unification fails anywhere, the parse is aborted and the tree is discarded. This allows the programmer to discard trees if features don't match.
// Sentence rules
// Intransitive verb:
// * Subject must be nominative case
// * Subject and verb must agree in number (copied through #1)
S -> N[ case: nom, num: #1 ] IV[ num: #1 ]
// Transitive verb:
// * Subject must be nominative case
// * Subject and verb must agree in number (copied through #2)
// * If there's a reflexive in the object position, make sure its `needs_pron`
// feature matches the subject's `pron` feature. If the object isn't a
// reflexive, then its `needs_pron` feature will implicitly be `**top**`, so
// will unify with anything.
S -> N[ case: nom, pron: #1, num: #2 ] TV[ num: #2 ] N[ case: acc, needs_pron: #1 ]
// Clausal verb:
// * Subject must be nominative case
// * Subject and verb must agree in number (copied through #1)
// * Reflexives can't cross clause boundaries (*"He said that she likes himself"),
// so we can ignore reflexives and delegate to inner clause rule
S -> N[ case: nom, num: #1 ] CV[ num: #1 ] Comp S
Now that we have this augmented grammar (available as examples/reflexives.fgr), we can try it out and see that it rejects illicit sentences that were previously accepted, while still accepting valid ones:
> he fell

If this is interesting to you and you want to learn more, you can check out my blog series, the excellent textbook Syntactic Theory: A Formal Introduction (2nd ed.), and the DELPH-IN project, whose work on the LKB inspired this simplified version.
Using from code
I need to write this section in more detail, but if you're comfortable with Rust, I suggest looking through the codebase. It's not perfect, it started as one of my first Rust projects (after migrating through F# -> TypeScript -> C in search of the right performance/ergonomics tradeoff), and it could use more tests, but overall it's not too bad.
Basically, the processing pipeline is:
- Make a
Grammarstruct
Grammaris defined inrules.rs.- The easiest way to make a
GrammarisGrammar::parse_from_file, which is mostly a hand-written recusive descent parser inparse_grammar.rs. Yes, I recognize the irony here.
- It takes input (in
Grammar::parse, which does everything for you, orGrammar::parse_chart, which just does the chart) - The input is first chart-parsed in
earley.rs - Then, a forest is built from the chart, in
forest.rs, using an algorithm I found in a very useful blog series I forget the URL for, because the algorithms in the academic literature for this are... weird. - Finally, the feature unification is used to prune the forest down to only valid trees. It would be more efficient to do this during parsing, but meh.
The most interesting thing you can do via code and not via the CLI is probably getting at the raw feature DAG, as that would let you do things like pronoun coreference. The DAG code is in featurestructure.rs, and should be fairly approachable -- there's a lot of Rust ceremony around Rc<RefCell<...>> because using an arena allocation crate seemed too harlike overkill, but that is somewhat mitigated by the NodeRef type alias.

Py Rouge: A Full Python Implementation Of The ROUGE Metric
Py-rouge
A full Python implementation of the ROUGE metric, producing same results as in the official perl implementation.
Important remarks
- The original Porter stemmer in NLTK is slightly different than the one use in the official ROUGE perl script as it has been written by end. Therefore, there might be slightly different stems for certain words. For DUC2004 dataset, I have identified these words and this script produces same stems.
- The official ROUGE perl script use resampling strategy to compute the average with confidence intervals. Therefore, we might have a difference
<3e-5for ROUGE-L as well as ROUGE-W and<4e-5for ROUGE-N. - Finally, ROUGE-1.5.5. has a bug: should have $tmpTextLen += $sLen at line 2101. Here, the last sentence, $limitBytes is taken instead of $limitBytes-$tmpTextLen (as $tmpTextLen is never updated with bytes length limit). It has been fixed in this code. This bug does not have a consequence for the default evaluation
-b 665.
In case of doubts, please see all the implemented tests to compare outputs between the official ROUGE-1.5.5 and this script.

A Plugin for D3.js That Allows You to Easy Use Context-menus
d3-context-menu
This is a plugin for d3.js that allows you to easy use context-menus in your visualizations. It's 100% d3 based and done in the "d3 way", so you don't need to worry about including additional frameworks.
Install with Bower
bower install d3-context-menu
Basic usage:
// Define your menu
var menu = [
{
title: 'Item #1',
action: function(d) {
console.log('Item #1 clicked!');
console.log('The data for this circle is: ' + d);
},
disabled: false // optional, defaults to false
},
{
title: 'Item #2',
action: function(d) {
console.log('You have clicked the second item!');
console.log('The data for this circle is: ' + d);
}
}
]
var data = [1, 2, 3];
var g = d3.select('body').append('svg')
.attr('width', 200)
.attr('height', 400)
.append('g');
g.selectAll('circles')
.data(data)
.enter()
.append('circle')
.attr('r', 30)
.attr('fill', 'steelblue')
.attr('cx', function(d) {
return 100;
})
.attr('cy', function(d) {
return d * 100;
})
.on('contextmenu', d3.contextMenu(menu)); // attach menu to element
});
Advanced usage:
Headers and Dividers
Menus can have Headers and Dividers. To specify a header simply don't define an "action" property. To specify a divider, simply add a "divider: true" property to the menu item, and it'll be considered a divider. Example menu definition:
var menu = [
{
title: 'Header',
},
{
title: 'Normal item',
action: function() {}
},
{
divider: true
},
{
title: 'Last item',
action: function() {}
}
];
Nested Menu
Menus can have Nested Menu. To specify a nested menu, simply add "children" property. Children has item of array.
var menu = [
{
title: 'Parent',
children: [
{
title: 'Child',
children: [
{
// header
title: 'Grand-Child1'
},
{
// normal
title: 'Grand-Child2',
action: function() {}
},
{
// divider
divider: true
},
{
// disable
title: 'Grand-Child3',
action: function() {}
}
]
}
]
},
];
See the index.htm file in the example folder to see this in action.
Pre-show callback
You can pass in a callback that will be executed before the context menu appears. This can be useful if you need something to close tooltips or perform some other task before the menu appears:
...
.on('contextmenu', d3.contextMenu(menu, function() {
console.log('Quick! Before the menu appears!');
})); // attach menu to element
Post-show callback
You can pass in a callback that will be executed after the context menu appears using the onClose option:
...
.on('contextmenu', d3.contextMenu(menu, {
onOpen: function() {
console.log('Quick! Before the menu appears!');
},
onClose: function() {
console.log('Menu has been closed.');
}
})); // attach menu to element
Context-sensitive menu items
You can use information from your context in menu names, simply specify a function for title which returns a string:
var menu = [
{
title: function(d) {
return 'Delete circle '+d.circleName;
},
action: function(d) {
// delete it
}
},
{
title: function(d) {
return 'Item 2';
},
action: function(d) {
// do nothing interesting
}
}
];
// Menu shown is:
[Delete Circle MyCircle]
[Item 2]
Dynamic menu list
You can also have different lists of menu items for different nodes if menu is a function:
var menu = function(data) {
if (data.x > 100) {
return [{
title: 'Item #1',
action: function(d) {
console.log('Item #1 clicked!');
console.log('The data for this circle is: ' + d);
}
}];
} else {
return [{
title: 'Item #1',
action: function(d) {
console.log('Item #1 clicked!');
console.log('The data for this circle is: ' + d);
}
}, {
title: 'Item #2',
action: function(d) {
console.log('Item #2 clicked!');
console.log('The data for this circle is: ' + d);
}
}];
}
};
// Menu shown for nodes with x < 100 contains 1 item, while other nodes have 2 menu items
Deleting Nodes Example
The following example shows how to add a right click menu to a tree diagram:
http://plnkr.co/edit/bDBe0xGX1mCLzqYGOqOS?p=info
Explicitly set menu position
Default position can be overwritten by providing a position option (either object or function returning an object):
...
.on('contextmenu', d3.contextMenu(menu, {
onOpen: function() {
...
},
onClose: function() {
...
},
position: {
top: 100,
left: 200
}
})); // attach menu to element
or
...
.on('contextmenu', d3.contextMenu(menu, {
onOpen: function() {
...
},
onClose: function() {
...
},
position: function(d) {
var elm = this;
var bounds = elm.getBoundingClientRect();
// eg. align bottom-left
return {
top: bounds.top + bounds.height,
left: bounds.left
}
}
})); // attach menu to element
Set your own CSS class as theme (make sure to style it)
d3.contextMenu(menu, {
...
theme: 'my-awesome-theme'
});
or
d3.contextMenu(menu, {
...
theme: function () {
if (foo) {
return 'my-foo-theme';
}
else {
return 'my-awesome-theme';
}
}
});
Close the context menu programatically (can be used as cleanup, as well)
d3.contextMenu('close');
The following example shows how to add a right click menu to a tree diagram:
http://plnkr.co/edit/bDBe0xGX1mCLzqYGOqOS?p=info
Additional callback arguments
Depending on the D3 library version used the callback functions can provide an additional argument:
- for D3 6.x or above it will be the event, since the global d3.event is not available.
var menu = [
{
title: 'Item #1',
action: function(d, event) {
console.log('Item #1 clicked!');
console.log('The data for this circle is: ' + d);
console.log('The event is: ' + event);
}
}
]
- for D3 5.x or below it will be the index, for backward compatibility reasons.
var menu = [
{
title: 'Item #1',
action: function(d, index) {
console.log('Item #1 clicked!');
console.log('The data for this circle is: ' + d);
console.log('The index is: ' + index);
}
}
]
What's new in version 2.1.0
- Added support for accessing event information in with D3 6.x.
What's new in version 2.0.0
- Added support for D3 6.x
- The
indexparameter of callbacks are undefined when using D3 6.x or above. See the index.htm file in the example folder to see how to get the properindexvalue in that case. - Added class property for menu items that allows specifying CSS classes (see: https://github.com/patorjk/d3-context-menu/pull/56).
What's new in version 1.1.2

themeconfiguration option (as string or function returning string) - onOpen/onClose callbacks now have consistent signature (they receive
dataandindex, andthisargument refers to the DOM element the context menu is related to) - all other functions (eg.
position,menu) have the same signature andthisobject asonClose/onOpen - Context menu now closes on
mousedownoutside of the menu, instead ofclickoutside (to mimic behaviour of the native context menu) disabledanddividercan now be functions as well and have the same signature andthisobject as explained above- Close the context menu programatically using
d3.contextMenu('close');
What's new in version 0.2.1
- Ability to set menu position
- Minified css and js versions
What's new in version 0.1.3
- Fixed issue where context menu element is never removed from DOM

#The White Lotus Season 1 Episode 1
Watch The White Lotus Season 1 Episode 1 Movie WEB-DL This is a file losslessly ripped from a streaming service, such as Netflix, Amazon
Video, Hulu, Crunchyroll, Discovery GO, BBC iPlayer, etc. This is also a movie or TV show downloaded via an online distribution website, such as iTunes. The quality is quite good since they are not re-encoded. The video (H.264 or H.265) and audio (AC3/The White Lotus Season 1 Episode 1 C) streams are usually extracted from the iTunes or Amazon Video and then remuxed into a MKV container without sacrificing quality.
Download Movie The White Lotus Season 1 Episode 1 One of the movie streaming industry’s largest impacts has been on the DVD industry, which
effectively met its demise with the mass popularization of online content. The rise of media streaming has caused the downfall of many DVD rental companies such as Blockbuster. In July 2015 an article from the New York Times published an article about Netflix’s DVD
services. It stated that Netflix is continuing their DVD services with 5.3 million subscribers, which is a significant drop from the
previous year. On the other hand, their streaming services have 65 million members. In a March 2016 study assessing the “Impact of Movie
Streaming over traditional DVD Movie Rental” it was found that respondents do not purchase DVD movies nearly as much anymore, if ever, as streaming has taken over the market. Watch Movie The White Lotus Season 1 Episode 1 , viewers did not find movie quality to be
significantly different between DVD and online streaming. Issues that respondents believed needed improvement with movie streaming
included functions of fast forwarding or rewinding, as well as search functions. The article highlights that the quality of movie
streaming as an industry will only increase in time, as advertising revenue continues to soar on a yearly basis throughout the industry, providing incentive for quality content production.
Watch The White Lotus Season 1 Episode 1 Movie Online Blu-ray or Bluray rips are encoded directly from the Blu-ray disc to 1080p or 720p (depending on disc source), and use the x264 codec. They can be ripped from BD25 or BD50 discs (or UHD Blu-ray at higher resolutions). BDRips are from a Blu-ray disc and encoded to a lower resolution from its source (i.e. 1080p to 720p/576p/480p). A BRRip is an already encoded video at an HD resolution (usually 1080p) that is then transcoded to a SD resolution. Watch The White Lotus Season 1 Episode 1 Movie BD/BRRip in DVDRip resolution looks better, regardless, because the encode is from a higher quality source. BRRips are only from an HD resolution to a SD resolution whereas BDRips can go from 2160p to 1080p, etc as long as they go downward in resolution of the source
disc. Watch The White Lotus Season 1 Episode 1 Movie FullBDRip is not a transcode and can fluxate downward for encoding, but BRRip can only go down to SD resolutions as they are transcoded. BD/BRRips in DVDRip resolutions can vary between XviD or x264 codecs (commonly 700 MB and 1.5 GB in size as well as larger DVD5 or DVD9: 4.5 GB or 8.4GB), size fluctuates depending on length and quality of releases, but the higher the size the more likely they use the x264 codec.

◇ STREAMING MEDIA ◇
Streaming media is multimedia that is constantly received by and presented to an end-user while being delivered by a provider. The verb to stream refers to the process of delivering or obtaining media in this manner.[clarification needed] Streaming refers to the delivery method of the medium, rather than the medium itself. Distinguishing delivery method from the media distributed applies specifically to telecommunications networks, as most of the delivery systems are either inherently streaming (e.g. radio, television, streaming apps) or inherently non-streaming (e.g. books, video cassettes, audio CDs). There are challenges with streaming content on the Internet. For example, users whose Internet connection lacks sufficient bandwidth may experience stops, lags, or slow buffering of the content. And users lacking compatible hardware or software systems may be unable to stream certain content. Live streaming is the delivery of Internet content in real-time much as live television broadcasts content over the airwaves via a television signal. Live internet streaming requires a form of source media (e.g. a video camera, an audio interface, screen capture software), an encoder to digitize the content, a media publisher, and a content delivery network to distribute and deliver the content. Live streaming does not need to be recorded at the origination point, although it frequently is. Streaming is an alternative to file downloading, a process in which the end-user obtains the entire file for the content before watching or listening to it. Through streaming, an end-user can use their media player to start playing digital video or digital audio content before the entire file has been transmitted. The term streaming media can apply to media other than video and audio, such as live closed captioning, ticker tape, and real-time text, which are all considered streaming text. Elevator music was among the earliest popular music available as streaming media; nowadays Internet television is a common form of streamed media. Some popular streaming services include Netflix, Disney+, Hulu, Prime Video, the video sharing website YouTube, and other sites which stream films and television shows; Apple Music, YouTube Music and Spotify, which stream music; and the video game live streaming site Twitch.
◇ COPYRIGHT ◇
Copyright is a type of intellectual property that gives its owner the exclusive right to make copies of a creative work, usually for a limited time. The creative work may be in a literary, artistic, educational, or musical form. Copyright is intended to protect the original expression of an idea in the form of a creative work, but not the idea itself. A copyright is subject to limitations based on public interest considerations, such as the fair use doctrine in the United States. Some jurisdictions require fixing copyrighted works in a tangible form. It is often shared among multiple authors, each of whom holds a set of rights to use or license the work, and who are commonly referred to as rights holders. [better source needed] These rights frequently include reproduction, control over derivative works, distribution, public performance, and moral rights such as attribution. Copyrights can be granted by public law and are in that case considered territorial rights. This means that copyrights granted by the law of a certain state, do not extend beyond the territory of that specific jurisdiction. Copyrights of this type vary by country; many countries, and sometimes a large group of countries, have made agreements with other countries on procedures applicable when works cross national borders or national rights are inconsistent. Typically, the public law duration of a copyright expires 50 to 100 years after the creator dies, depending on the jurisdiction. Some countries require certain copyright formalities to establishing copyright, others recognize copyright in any completed work, without a formal registration. In general, many believe that the long copyright duration guarantees the better protection of works. However, several scholars argue that the longer duration does not improve the author’s earnings while impeding cultural creativity and diversity. On the contrast, a shortened copyright duration can increase the earnings of authors from their works and enhance cultural diversity and creativity.
◇ MOVIES / FILM ◇
Movies, or films, are a type of visual communication which uses moving pictures and sound to tell stories or teach people something. Most people watch (view) movies as a type of entertainment or a way to have fun. For some people, fun movies can mean movies that make them laugh, while for others it can mean movies that make them cry, or feel afraid. It is widely believed that copyrights are a must to foster cultural diversity and creativity. However, Parc argues that contrary to prevailing beliefs, imitation and copying do not restrict cultural creativity or diversity but in fact support them further. This argument has been supported by many examples such as Millet and Van Gogh, Picasso, Manet, and Monet, etc. Most movies are made so that they can be shown on screen in Cinemas and at home. After movies are shown in Cinemas for a period of a few weeks or months, they may be marketed through several other medias. They are shown on pay television or cable television, and sold or rented on DVD disks or videocassette tapes, so that people can watch the movies at home. You can also download or stream movies. Older movies are shown on television broadcasting stations. A movie camera or video camera takes pictures very quickly, usually at 24 or 25 pictures (frames) every second. When a movie projector, a computer, or a television shows the pictures at that rate, it looks like the things shown in the set of pictures are really moving. Sound is either recorded at the same time, or added later. The sounds in a movie usually include the sounds of people talking (which is called dialogue), music (which is called the soundtrack), and sound effects, the sounds of activities that are happening in the movie (such as doors opening or guns being fired).
In the 20th century the camera used photographic film. The product is still often called a film even though there usually is no film. A genre is a word for a type of movie or a style of movie. Movies can be fictional (made up), or documentary (showing ‘real life’), or a mix of the two. Although hundreds of movies are made every year, there are very few that do not follow a small number of set plots, or stories. Some movies mix together two or more genres.
Action movies have a lot of exciting effects like car chases and gun fights, involving stuntmen. They usually involve ‘goodies’ and ‘baddies’, so war and crime are common subjects. Action movies usually need very little effort to watch, since the plot is normally simple. For example, in Die Hard, terrorists take control of a skyscraper and ask for a big ransom in exchange for not killing the hostage workers. One hero somehow manages to save everyone. Action movies do not usually make people cry, but if the action movie is also a drama, emotion will be involved. Adventure Movies usually involve a hero who sets out on a quest to save the world or loved ones.
Animated movies use artificial images like talking cartoons to tell a story. These movies used to be drawn by hand, one frame at a time, but are now made on computers. Buddy movies involve 2 heroes, one must save the other, both must overcome obstacles. Buddy movies often involve comedy, but there is also some emotion, because of the close friendship between the ‘buddies’. Comedies are funny movies about people being silly or doing unusual things or being in silly or unusual situations that make the audience laugh. Documentaries are movies that are (or claim to be) about real people and real events.
They are nearly always serious and may involve strongly emotional subjects, for example cruelty. Dramas are serious, and often about people falling in love or needing to make a big decision in their life. They tell stories about relationships between people. They usually follow a basic plot where one or two main characters (each actor plays a character) have to ‘overcome’ (get past) an obstacle (the thing stopping them) to get what they want. Tragedies are always dramas, and are about people in trouble. For example, a husband and wife who are divorcing must each try to prove to a court of law that they are the best person to take care of their child. Emotion (feelings) are a big part of the movie and the audience (people watching the movie) may get upset and even cry.
Film noir movies are 1940s-era detective dramas about crime and violence. Family movies are made to be good for the entire family. They are mainly made for children but often entertaining for adults as well. Disney is famous for their family movies. Horror movies use fear to excite the audience. Music, lighting and sets (man-made places in movie studios where the movie is made) are all designed to add to the feeling. Romantic Comedies (Rom-Coms) are usually love stories about 2 people from different worlds, who must overcome obstacles to be together. Rom-Coms are usually light-hearten, but may include some emotion. Comedy horror movies blend horror and comic motifs in its plots. Movies in this genre sometimes use black comedy as the main form of humor. Science fiction movies are set in the future or in outer space. Some use their future or alien settings to ask questions about the meaning of life or how we should think about life. Science fiction movies often use special effects to create images of alien worlds, outer space, alien creatures, and spaceships. Fantasy movies include magical and impossible things that any real human being cannot do. Thrillers are usually about a mystery, strange event, or crime that needs to be solved. The audience is kept guessing until the final minutes, when there are usually ‘twists’ in the plot (surprises). Suspense movies keep you on the edge of your seat. They usually have multiple twists that confuse the watcher. Western movies tell stories about cowboys in the western United States in the 1870s and 1880s. They are usually action movies, but with historical costumes. Some involve Native Americans. Not all films that are set in the American West are made there. For example, Western films made in Italy are called Spaghetti Westerns. Some films can also use Western plots even if they are set in other places.
