YAEP is an abbreviation of Yet Another Earley Parser. The package `YAEP' implements earley parser. The earley parser implementation has the following features:
The interface part of the parser is file `yaep.h'. The implementation part is file `yaep.c'. The interface contains the following external definitions and macros:
describes a grammar. Knowledge of structure (implementation) of this type is not visible and not needed for using the parser.
is reserved to be designation of empty node for translation.
is error code of the parser. The parser functions return the code when parser can not allocate enough memory for its work.
is error code of the parser. The parser functions return the code when we call parsing without defining grammar or call parsing for bad defined grammar.
is error code of the parser. The code is returned when the grammar is defined by description and there is syntax error in the description.
is error code of the parser. The code is returned when the grammar uses reserved names for terminals and nonterminals. There are two reserved names `$S' (for axiom) and `$eof' for end of file (input end marker). The parser adds these symbols and rules with these symbols to the grammar given by user. So user should not use these names in his grammar.
is error code of the parser. The code is returned when the grammar contains several declarations of terminals with the same name.
is error code of the parser. The code is returned when the grammar terminal is described with negative code.
is error code of the parser. The code is returned when the two or more grammar terminals are described with the same code.
is error code of the parser. The code is returned when the grammar given by user has no rules.
is error code of the parser. The code is returned when grammar rule given by user contains terminal in left hand side of the rule.
is error code of the parser. The code is returned when grammar rule translation is not correct. The single reason for this is translation of the rule consists of translations of more one symbols in the right hand side of the rule without forming an abstract tree node.
is error code of the parser. The code is returned when abstract node has a negative cost.
is error code of the parser. The code is returned when grammar rule translation contains incorrect symbol number which should be nonnegative number less than rule right hand side length.
is error code of the parser. The code is returned when there is grammar nonterminal which can not be derived from axiom.
is error code of the parser. The code is returned when there is grammar nonterminal which can not derive a terminal string.
is error code of the parser. The code is returned when there is grammar nonterminal which can derive only itself. The parser does not work with such grammars.
is error code of the parser. The code is returned when the parser got input token whose code is different from all grammar terminal codes.
describes all possible nodes of abstract tree representing the translation. There are the following enumeration constants:
the corresponding node represents empty translations.
the corresponding node represents translation of special terminal `error' (see error recovery).
the corresponding node represents translation of a terminal.
the corresponding node represents an abstract node.
the corresponding node represents an alternative of the translation. Such nodes creates only when there are two or more possible translations. It means that the grammar is ambiguous.
represents node of the translation. The nodes refer for each other forming DAG (direct acyclic graph) in general case. The main reason of generating DAG is that some input fragments may have the same translation, when there are several parsings of input (which is possible only for ambiguous grammars). But DAG may be created even for unambigous grammar because some nodes (empty and error nodes) exist only in one exemplar. When such nodes are not created, the translation nodes forms a tree. This structure has the following members:
representing type of the translation node.
Depending on the translation node type, one of the union members `nil', `error', `term', `anode', and `alt' of the structure types described below is used to represent the translation node.
represents empty node. It has no members. Actually the translation is DAG (not tree) in general case. The empty and error nodes are present only in one exemplar.
represents translation of special terminal `error'. It has no members. The error node exists only in one exemplar.
represents translation of terminals. It has the following two members:
representing code of the corresponding terminal.
is reference for the attribute of the corresponding terminal.
represents abstract node. It has the following two members:
representing name of anode as it given in the corresponding rule translation.
representing cost of the node plus costs of all children if the cost flag is set up. Otherwise, the value is cost of the abstract node itself.
is array of nodes representing the translations of the symbols given in the rule with the abstract node.
represents an alternative of the translation. It has the following two members:
representing alternative translation.
is reference for the next alternative of translation.
`struct grammar *yaep_create_grammar (void)'
should be called the first. It actually creates an yaep
parser with undefined grammar. You can use two or more
parsers simultaneously. The function returns `NULL' if
there is no memory.
`int yaep_error_code (struct grammar *g)'
returns the last occurred error code (see the possible error
codes above) for given parser. If the function returns
zero, no error was found so far.
`const char *yaep_error_message (struct grammar *g)'
returns detail message about last occurred error. The
message always corresponds to the last error code returned
the previous function.
`int yaep_read_grammar (struct grammar *g, int strict_p,
const char *(*read_terminal) (int *code),
const char *(*read_rule)
(const char ***rhs,
const char **abs_node,
int *anode_cost,
int **transl))'
is one of two functions which tunes the parser to given
grammar. The grammar is read with the aid functions given
as parameters.
`read_terminal' is function for reading terminals. This function is called before function `read_rule'. The function should return the name and the code of the next terminal. If all terminals have been read the function returns NULL. The terminal code should be nonnegative.
`read_rule' is function called to read the next rule. This function is called after function `read_terminal'. The function should return the name of nonterminal in the left hand side of the rule and array of names of symbols in the right hand side of the rule (the array end marker should be `NULL'). If all rules have been read, the function returns `NULL'. All symbol with name which was not provided function `read_terminal' are considered to be nonterminals. The function also returns translation given by abstract node name and its fields which will be translation of symbols (with indexes given in array given by parameter `transl') in the right hand side of the rule. All indexes in `transl' should be different (so the translation of a symbol can not be represented twice). The end marker of the array should be a negative value. There is a reserved value of the translation symbol number denoting empty node. It is value defined by macro `YAEP_NIL_TRANSLATION_NUMBER'. If parameter `transl' is `NULL' or contains only the end marker, translations of the rule will be empty node. If `abs_node' is `NULL', abstract node is not created. In this case `transl' should be null or contain at most one element. This means that the translation of the rule will be correspondingly empty node or the translation of the symbol in the right hand side given by the single array element. The cost of the abstract node if given is passed through parameter `anode_cost'. If `abs_node' is not `NULL', the cost should be greater or equal to zero. Otherwise the cost is ignored.
There is reserved terminal `error' which is used to mark start point of error recovery.
Nonzero parameter `strict_p' value means more strict checking the grammar. In this case, all nonterminals will be checked on ability to derive a terminal string instead of only checking axiom for this.
The function returns zero if it is all ok. Otherwise, the function returns the error code occured.
`int yaep_parse_grammar (struct grammar *g, int strict_p,
const char *description)'
is another function which tunes the parser to given grammar.
The grammar is given by string `description'. The
description is similiar YACC one. It has the following
syntax:
file : file terms [';']
| file rule
| terms [';']
| rule
terms : terms IDENTIFIER ['=' NUMBER]
| TERM
rule : IDENTIFIER ':' rhs [';']
rhs : rhs '|' sequence [translation]
| sequence [translation]
sequence :
| sequence IDENTIFIER
| sequence C_CHARACTER_CONSTANT
translation : '#'
| '#' NUMBER
| '#' '-'
| '#' IDENTIFIER [NUMBER] '(' numbers ')'
numbers :
| numbers NUMBER
| numbers '-'
So the description consists of terminal declaration and
rules sections.
Terminal declaration section describes name of terminals and their codes. Terminal code is optional. If it is omitted, the terminal code will the next free code starting with 256. You can declare terminal several times (the single condition its code should be the same).
Character constant present in the rules is a terminal described by default. Its code is always code of the character constant.
Rules syntax is the same as YACC rule syntax. The single difference is an optional translation construction starting with `#' right after each alternative. The translation part could be a single number which means that the translation of the alternative will be the translation of the symbol with given number (symbol numbers in alternative starts with 0). Or the translation can be empty or `-' which mean empty node. Or the translation can be abstract node with given name, optional cost, and with fields whose values are the translations of the alternative symbols with numbers given in parentheses after the abstract node name. You can use `-' in abstract node to show that empty node should be used in this place. If the cost is absent it is believed to be one. The cost of terminal, error node, and empty node is always zero.
There is reserved terminal `error' which is used to mark start point of error recovery.
`int yaep_set_lookahead_level (struct grammar *grammar,
int level)'
sets up level of usage of look ahead in parser work. Value
zero means no usage of lookaheads at all. Lookahead with
static (independent on input tokens) context sets in parser
situation (value 1) gives the best results with the point of
view of space and speed, lookahead with dynamic (dependent
on input tokens) context sets in parser situations (all the
rest parameter values) does slightly worse, and no usage of
lookaheads does the worst. The default value is 1
(lookahead with static situation context sets). The
function returns the previously set up level. If the level
value is negative, zero is used instead of it. If the value
is greater than two, two is used in this case.
`int yaep_set_debug_level (struct grammar *grammar,
int level)'
sets up level of debugging information output to `stderr'.
The more level, the more information is output. The default
value is 0 (no output). The debugging information includes
statistics, result translation tree, grammar, parser sets,
parser sets with all situations, situations with
contexts. The function returns the previously set up debug
level. Setting up negative debug level results in output of
translation for program `dot' of graphic visualization
package `graphviz'.
`int yaep_set_one_parse_flag (struct grammar *grammar,
int flag)'
sets up building only one translation tree (parameter value
0) or all parse trees for ambiguous grammar for which
several parsings are possible. For unambiguous grammar the
flag does not affect the result. The default value is 1.
The function returns the previously used flag value.
`int yaep_set_cost_flag (struct grammar *grammar, int flag)'
sets up building only translation tree (trees if we set up
one_parse_flag to 0) with minimal cost. For unambiguous
grammar the flag does not affect the result. The default
value is 0. The function returns the previously used flag
value.
`int yaep_set_error_recovery_flag (struct grammar *grammar,
int flag)'
sets up internal flag whose nonzero value means making error
recovery if syntax error occurred. Otherwise, syntax error
results in finishing parsing (although function
`syntax_error' in function `yaep_parse' will be called
once). The default value is 1. The function returns the
previously used flag value.
`int yaep_set_recovery_match (struct grammar *grammar,
int n_toks)'
sets up recovery parameter which means how much subsequent
tokens should be successfully shifted to finish error
recovery. The default value is 3. The function returns the
previously used flag value.
`int yaep_parse (struct grammar *grammar,
int (*read_token) (void **attr),
void (*syntax_error)
(int err_tok_num, void *err_tok_attr,
int start_ignored_tok_num,
void *start_ignored_tok_attr,
int start_recovered_tok_num,
void *start_recovered_tok_attr),
void *(*parse_alloc) (int nmemb),
void (*parse_free) (void *mem),
struct yaep_tree_node **root,
int *ambiguous_p)'
is major parser function. It parses input according the
grammar. The function returns the error code (which can be
also returned by `yaep_error_code'). If the code is
zero, the function will also return root of the parse tree
through parameter `root'. The tree representing the
translation. Value passed through `root' will be `NULL'
only if syntax error was occurred and error recovery was
switched off. The function sets up flag passed by
parameter `ambiguous_p' if we found that the grammar is
ambiguous (it works even we asked only one parse tree
without alternatives).
Function `read_token' provides input tokens. It returns code the next input token and its attribute. If the function returns negative value we've read all tokens.
Function `syntax_error' called when synatctic error has been found. It may print an error message about syntax error which occurred on token with number `err_tok_num' and attribute `err_tok_attr'. The following four parameters describes made error recovery which ignored tokens starting with token given by 3rd and 4th parameters. The first token which was not ignored is described by the last parameters. If the number of ignored tokens is zero, the all parameters describes the same token. If the error recovery is switched off (see comments for `yaep_set_error_recovery_flag'), the third and the fifth parameters will be negative and the forth and the sixth parameters will be `NULL'.
Function `parse_alloc' is used by YAEP to allocate memory for parse tree representation (translation). After calling `yaep_free_grammar' we free all memory allocated for the parser. At this point it is convenient to free all memory but parse tree. Therefore we require the following function. So the caller will be responsible to allocate and free memory for parse tree representation (translation). But the caller should not free the memory until `yaep_free_grammar' is called for the parser. The function may be called even during reading the grammar not only during the parsing. Function `parse_free' is used by the parser to free memory allocated by `parse_alloc'. If it is `NULL', the memory is not freed.
`void yaep_free_grammar (struct grammar *grammar)'
frees all memory allocated for the parser. This function
should be called the last for given parser.


How it works
This CGPA calculator has Firebase as it's backend. Firebase is an Advanced cloud platform, a derivative of Google Cloud Platform, which has it's database in JSON format. Firebase offers various tools and kits for app development which includes Analytics, Cloud messaging, Real-time database, App indexing etc.,
All the data, from account creation to GPA calculation, are stored as a larger JSON object. Everytime a user logins, his JSON object is retrieved and changes are made. Since Firebase is a real-time database, all of the changes made are immediately affected to all other nodes (devices) which has your account logged-in. So, you are always up-to-date with your changes and updations.
When a calculation is made with this CGPA Calculator, the data are sent to the database first and a device-copy is locally saved. This enables the app to access your data even when you are offline. When changes are made while you are offline, the changes are made locally. And when device goes online again, all of the data locally stored are sent to the database. Thus, you always the latest data synced.
Why Firebase
Firebase has been evolved as a better BaaS (Backend as a Service) from since when Google acquired it. It offers offline capabilities to the application and much more similar features. Firebase supports in making real-time changes, analytics and cloud messaging which makes it more suit for this CGPA Calculator project. These features will make this an insanely great project than other standard CGPA Calculators.
This CGPA Calculator project is an open-source project.

Glover's maximum matching in a bipartite graph.
Compute a matching in the bipartite convex intersection graph with one partition containing the x views and the other containing the y views. The algorithm works with an implicit array structure of the intersection graph.
Union-Find Implementation of F.Glover's matching algorithm.
The idea is to mimick a priority queue storing x-indices , s.t. the upper domain bounds are sorted where is the top element

Compute the sccs of the oriented intersection-graph.
An y-node and its corresponding matching mate form the smallest possible scc, since both edges and are both contained in the oriented intersection graph.
Hence a scc containg more than two nodes is represented as an array of SccComponent entries, .

Narrowing the domains of the x variables.
Due to the correspondance between perfect matchings in the "reduced" intersection graph of x and y views and feasible assignments for the sorted constraint the new domain bounds for views in x are computed as

Perform bounds consistent sortedness propagation.
Implements the propagation algorithm for Sorted::Sorted and is provided as seperate function, because a second pass of the propagation algorithm is needed in order to achieve idempotency in case explicit permutation variables are provided.
If Perm is true, permutation variables form the third argument which implies additional inferences, consistency check on the permutation variables and eventually a second pass of the propagation algorithm. Otherwise, the algorithm does not take care of the permutation variables resulting in a better performance.

Subsumption test.
The propagator for sorted is subsumed if all variables of the ViewArrays x, y and z are determined and the constraint holds. In addition to the subsumption test check_subsumption determines, whether we can reduce the orginial problem to a smaller one, by dropping already matched variables.

This project was shut down in April 2017 after about a month of existence.
The first exercise is here. I'll add more soon.
When I studied English, I had a book with hundreds of grammar exercises. It looked like this.
It wasn't enough just to read the grammar rule once. I had to solve tons of exercises to install the rule into my brain.
Learning Python doesn't differ too much from learning English. But for some reason people don't do enough grammar exercises in Python. They go straight to the big projects.
I agree that projects are great. But making project without learning the grammar first is as painful as surviving in English-speaking country with just a dictionary (given that you don't know English). It is very difficult!
So, we do need grammar books for programming languages.
I've tested embedding exercises from repl.it and it works! So now I'm developing the first set of exercises and some nice html and css to wrap them.
You can contribute exercises! You can contribute everything, speak-code is open source!
Send a pull-request to our repo on Github!
Moreover, you can start following our updates by filling this form.


Value Provider Conditions¶
When a visitor browses to your site, we might already have a lot of information on him based on his xDB tracking cookie. When prefilling of forms is enabled by use of the fieldbindings, we can prefill the form fields from xDB. This might not always be the desired behaviour, there may be cases where you only want to prefill when a user is logged in, or has given concent to prefill the form.
With the Value Provider Conditions, you can build rules that must be met, before prefilling is applied.
How to create a set of rules¶
In the content explorer, navigate to /sitecore/system/Settings/Forms/Value Provider Conditions
Create a new ValueProviderConditions item.
Next, click on “Edit Rule” and build the conditional rule you desire.
Save and publish the rule.
How to use a set of rules¶
In the content explorer, navigate to your form. (Sitecore –> Forms –> Your Form)
In the Value Provider section, choose your conditions.
Save and publish the form.

Issue: DEFSTRUCT-INCLUDE-DEFTYPEForum: Editorial
References: DEFSTRUCT's :INCLUDE option (pp312-314)
Category: CLARIFICATION
Edit history: 01-Mar-91, Version 1 by Pitman
Status: For X3J13 consideration
Problem Description:
From time to time, people ask whether they can specify in a :INCLUDE
to DEFSTRUCT the name of a type which is defined by DEFTYPE to expand
into a type that was defined by DEFSTRUCT.
Proposal (DEFSTRUCT-INCLUDE-DEFTYPE:EXPLICITLY-UNDEFINED):
Clarify that the only names which are permissible as type names to
the :INCLUDE option of DEFSTRUCT are actual names previously defined
by DEFSTRUCT.
Clarify that one implication of this is that the consequences are
undefined if a type given to DEFSTRUCT's :INCLUDE option is a type
defined by DEFTYPE, even if it expands into a type defined by DEFSTRUCT.
Test Case:
(DEFSTRUCT FOO A B)
(DEFTYPE FU () 'FOO)
(DEFSTRUCT (BAR (:INCLUDE FU)) C)
Rationale:
Permitting DEFTYPE-defined types here might open the door to other
inconsistencies with DEFTYPE-defined types not being accepted in other
`reasonable' places.
Most implementations probably don't allow this and a change would
be extra work for implementors.
Current Practice:
Symbolics Genera signals an error if the :INCLUDE'd type was not
specifically defined by DEFSTRUCT.
Cost to Implementors:
None. "The consequences are undefined" leaves implementations free to
do whatever they want.
Cost to Users:
None. Users de facto can't really rely on this now so portable
programs shouldn't be effected.
Cost of Non-Adoption:
Some users will continue to be puzzled about whether the perceived-to-be
fascist behavior of some implementations is what was intended.
Benefits:
Users will know what to expect.
Aesthetics:
Doing the full job of making DEFTYPE-defined types acceptable in any
place might be aesthetic, but that's not what is proposed here, and making
a lot of little special case exceptions probably isn't so aesthetic.
Discussion:
Pitman supports this proposal.


The Result is : $ per month
Calculated for 1GB application storage
Note: These costs are the minimum costs incurred per month. Additional costs can include, costs per GB for storage and database, costs for the need of multiple VMs, License costs, Consulting costs, Custom Hosting charges, VM Upgrade charges, Hosting Additional Software charges, etc.
Ministries incur zero costs for infrastructure but need to incur costs for an agile team to continuously manage and monitor the application on OpenShift

Sebastien Baehni While working on his PhD in communication systems to add to his Master of Computer Science degree, Sebastien Baehni spends approximately 30 hours per week on Project JXTA. He is a contributor on the platform and the jxta-wire modules. Seb has developed a small chat application (inspired by the hotwire service) in order to create a tutorial upon the jxta-wire service. He is also developing a typed-based publish-subscribe application (and API) to see what JXTA can offer for such a paradigm. This application is using JXTA and the new genericity package generic java in order to be more efficient. Seb thinks that P2P applications are the future of the Internet and that trying to create a framework for developing such applications is a great thing. He says that Project JXTA is very interesting to him from these two points of view: Project point of view:

New Site!
Frequent visitors to the site may have noticed some big changes this week! With the resources of Avalara’s Incubator team, we’ve launched a brand new site that offers a number of great improvements. Jekyll. With the old site, we were managing site plugins and platform-specific integrations. This was slowing us down, and slowing down the site. The new site is based on a static page generator, Jekyll, which allows us to manage things more easily and to load pages faster. Open source all the docs: Jekyll runs off of a series of markdown files, which we’ve made public on GitHub....
Tax Rates Client Library for Node
The Avalara Developer Relations team is boldly going (cue music) into node.js. We released our first node.js helper library in August for the TaxRates.com API. This is our free and simple API for getting sales tax rates and authorities based on a street address or zip/postal code in the U.S. or Canada. The new node.js library makes it easy to integrate it into your node-based projects. You can find sample code in the readme of the TaxRates-node Github repository. You can also embed it in your node.js project: npm install avalara-taxrates. I cannot give a definitive statement on when our...
Performance Optimization of the AvaTax Core Calculation Platform
Over the past year we’ve invested in our core tax calculation engine, growing SAits features, expanding its reach, and making it faster and faster. This has presented some amazing challenges, especially to materially speed up a service while its transactional load grows by 60% annually. Simply keeping up with that level of growth can be a challenge. So, how did we manage to more than triple the speed at which our current engine calculates and returns information while keeping it stable, growing, and expanding? The improvement can be clearly seen in our internal latency metrics for typical tax documents over...

Avalara just posted a new version of our AvaTax terms and conditions, effective January 1, 2016.

If Customer does submit Documents to the AvaTax Service in a billing month, but usage of the AvaTax APIs or the number of invoice lines submitted significantly exceeds ordinary AvaTax usage in that month, the following calculations may be used to determine “Document” usage during that month: 1. Every 50 API calls to the address validation service will count as one “Document”; 2....

LA TRAVIATA
A film review by Cooper Redwine Copyright 1997 Cooper Redwine
Director: Franco Zeffirelli. Starring: Teresa Stratas, Placido Domingo, Cornell MacNeil. Screenplay: Franco Zeffirelli. Music: Giuseppe Verdi. Libretto: Francesco Maria Piave. Production Design: Franco Zeffirelli. Costume Design: Piero Tosi. Producer: Tarak Ben Ammar. MPAA Rating: G. Running Time: 105 minutes.
INTRODUCTION
About twelve minutes into his film version of LA TRAVIATA, Franco Zeffirelli brilliantly captures one of the most joyous scenes in all opera: At a glittering, festive party, Alfredo (played by tenor Placido Domingo) is called upon to make a toast, and he responds with the famous "Il Brindisi" ("The Drinking Song"). The catchy melody he sings is then repeated by Violetta (played by soprano Teresa Stratas). A few moments later, that melody is picked up by the Chorus of the Metropolitan Opera, and it becomes obvious that Alfredo and Violetta are falling in love. Every time I see this scene I am reminded of something Kenneth Clark once said while standing on the Pont des Arts in Paris: "What is civilization? I don't know. I can't define it in abstract terms. But I think I can recognize it when I see it; and I am looking at it now."
In his early career, Zeffirelli was mainly involved in stage productions, which provided much of the background he needed later for his noted screen adaptations of Shakespearean plays (ROMEO AND JULIET, THE TAMING OF THE SHREW, HAMLET). Zeffirelli's stage work included extensive opera experience, so it is not surprising that he made a dazzling screen version of LA TRAVIATA, bringing to it his trademark use of charming locations, extravagant sets, and magnificent costumes. Zeffirelli's ability to deal with spectacle is evident in nearly all his films, but ROMEO AND JULIET and the cult favorite BROTHER SUN, SISTER MOON (the life story of St. Francis of Assisi) show that he can also handle intimate, poetic material well, and the balance achieved between the intimate and the spectacular in LA TRAVIATA is masterful. Zeffirelli has often been criticized for his unabashed sentimentality, but in LA TRAVIATA the story and the music make this quality an asset rather than a liability.
Zeffirelli designed his film version of LA TRAVIATA expressly for the movie medium, and the look and feel of it are not much like that of a filmed stage performance. Most of the story is presented during one long flashback, and on several occasions, the film shows the visual images in characters' minds. More importantly, the principal singers are good film actors, generally avoiding the theatrics required for a live performance at a large opera house or in the concert hall. For the most part, the facial expressions and subtle body language in close-ups are just right, and I found myself caring a lot about the fate of the people in the story. Also, I think there is good screen chemistry between Stratas and Domingo, and at first viewing, the movie can be enjoyed as a simple story of doomed love. But I have found a deeper satisfaction after watching the film many times because that's what it took for me to appreciate the psychological complexity of the characters and Zeffirelli's visually dense treatment of them. In contrast, Giuseppe Verdi's music is rather simple, but it is varied and tuneful and, above all, emotional.
BACKGROUND
Verdi took the story for his opera from the 1852 French play LA DAME AUX CAMELIAS (THE LADY OF THE CAMELLIAS) by Alexander Dumas the Younger. Dumas based his title character on an actual person who died at age 24 of tuberculosis in 1847. The woman was called Marie Duplessis, and to this day people still put flowers on her grave in Paris. Dumas originally named his fictional heroine Marguerite Gauthier, but she became generally known in America as Camille because the name was changed in the touring stage version popularized by the famous actress Sarah Bernhardt. Several movie versions were eventually made of the story, the best known of which is the classic 1936 Hollywood film CAMILLE, starring Greta Garbo.
Verdi saw the play LA DAME AUX CAMELIAS in Paris shortly after its premiere and, working with a libretto by Francesco Maria Piave, developed the material into the Italian opera LA TRAVIATA. There seems to be no completely satisfactory translation of Verdi's title into English, but perhaps the literal, if awkward, SHE WHO HAS STRAYED conveys the meaning adequately. Although the opera retains the Paris setting of the Dumas story, the characters have been renamed, and all of the first names are Italian. In particular, the main character in the opera is called Violetta Valery.
Verdi had already written more than a dozen successful operas before LA TRAVIATA, but when it was first performed in 1853 at Teatro Fenice in Venice, it flopped. It seems likely that audiences were startled by what was at the time novel subject matter, as well as by the romanticism of the music, and these difficulties may have been compounded by production problems. After only two performances, LA TRAVIATA was taken off the boards. But when a slightly revamped version was performed fourteen months later, it caught on, and the work has remained popular for over 140 years. One of the most famous singers to regularly perform the role of Violetta has been Maria Callas, and Zeffirelli worked with her on some productions. Incidentally, opera legend has it that one of the reasons for the failure of the initial production of LA TRAVIATA was that the Venetians openly snickered at the idea that the overly plump soprano playing Violetta was wasting away from tuberculosis. In this connection, it should be noted that Teresa Stratas, the Violetta in Zeffirelli's film, is appropriately slender.
The social setting depicted in LA TRAVIATA probably needs a little explanation for modern audiences.  Such women exercised considerable independence and often entered into mutually convenient arrangements with wealthy men. The man in such an arrangement was sometimes called the woman's "protector." While the social standing of members of the demimonde was below that of women of unquestioned respectability, it was still well above that of the courtesan class, and it would be a mistake to think that 1850's opera goers regarded Violetta as a prostitute.
SYNOPSIS
While the title credits roll at the beginning of Zeffirelli's LA TRAVIATA, the screen is filled with beautiful wintry location shots of parts of Paris, such as Notre Dame and the Seine, that look much the same today as they did around 1850. In an unlit house, workmen are quietly removing objets d'art, while a gravely ill woman lies alone in bed, coughing. The woman is the consumptive heroine Violetta, whose possessions are being taken to cover debts she has incurred. One of the workmen, a very young man, pauses to stare at a large portrait of Violetta, and the Metropolitan Opera Orchestra plays the haunting love theme that comes to symbolize Alfredo's devotion. Violetta rises momentarily from what will be her deathbed and looks toward a large darkened room where workmen are moving about, and in her mind she is transported back to the pivotal night of her life, a night when the house was brightly lit and filled with a noisy party crowd. It is then that the singing begins, in Italian, with an English translation displayed in subtitles at the bottom of the screen.
Violetta is hosting a lavish summer party at her extravagantly furnished home. She is accompanied by her protector, Baron Douphol, who does not live with her, and it quickly becomes apparent that her relationship with the Baron is a loveless one. Violetta's tuberculosis gives her some bad moments, but her health is still good enough that she can enjoy most of the festivities. At the party, she is introduced to Alfredo Germont, who has loved her from afar for a year. Alone with her briefly, Alfredo declares his love in the aria "Un di felice, eterea" (here the subtitles read "One day, so radiant and ethereal"), which includes the love theme melody mentioned earlier. Later the guests depart, and left alone with her thoughts, Violetta begins the famous aria "Ah, fors' e lui che l'anima," as the words "It must be him whose portrait my soul" appear in the subtitles. As part of an interior monologue, she goes on to sing the love theme melody, but then she suddenly snaps out of her meditation with the realization that yielding to her desire to love Alfredo would be folly, at which point she sings the flashy "Sempre libera degg'io" ("I must be forever free"). However, in her imagination she still sees Alfredo and hears his voice reprising the love theme, and as the screen fades to black, it is clear that she will not be able to suppress the love she feels for him.
Zeffirelli's film makes a visually pleasing transition from Paris to a nearby country villa where Violetta and Alfredo live together for three happy months. Violetta's health appears to have improved, and she and Alfredo are shown enjoying a variety of simple outdoor activities during a golden autumn. For example, Violetta is shown trying to cross a log over a shallow stream to reach Alfredo, but she loses her balance and falls in. When Alfredo bends to help her out, he too gets pulled into the stream, and they laugh and share a kiss. Then, at a time when Alfredo is away for a few hours, his father (played by baritone Cornell MacNeil) pays Violetta a visit at the charming, secluded villa. The elder Germont demands that Violetta break with Alfredo because their relationship is jeopardizing the marriage prospects of his daughter. Violetta reluctantly agrees to the demand, believing that her sacrifice is necessary to the happiness of the Germont family. With great sadness, she realizes that she must go back to the Baron since if she remains alone, Alfredo will follow her. Unaware of what has happened, Alfredo returns to the villa and is shocked when Violetta abruptly leaves him. He mistakenly believes that she has grown tired of him and he has been dumped so she can resume the exciting life she used to lead. Although he attributes Violetta's actions to the wrong motive, Alfredo correctly guesses her next move, and in an agitated state he heads for a demimonde party that will be held that evening.
The scene shifts to an elaborate party in Paris, complete with singing and dancing gypsies and matadors. Zeffirelli enhances the diversion by including ballet dancers, two of whom are from the Bolshoi. Alfredo enters alone, and soon Violetta arrives on the arm of her old protector, Baron Douphol. It is clear from the outset that the Baron and Alfredo are both leaning towards provoking the other into a duel. Alfredo joins a card game where he gambles recklessly and wins, while the Baron loses. Supper is announced, and after a tense exchange between Alfredo and the Baron, Violetta and Alfredo meet privately for a moment. Alfredo angrily presses her for explanations, and the only way she can keep her promise to his father is by telling him the lie that she loves the Baron. In a jealous rage Alfredo drags Violetta to the dining area and calls for the assembled guests to watch while he insultingly throws his gambling winnings at her in payment for the time they have spent together. Violetta is devastated, and everyone condemns Alfredo's shameful behavior. As the scene draws to a close, the Baron challenges Alfredo to a duel.
The long flashback that began with the dying Violetta looking toward the large darkened room near the beginning of the film finally comes to an end. Apparently three or four months have passed since the Baron challenged Alfredo to a duel, and Violetta has not been in contact with Alfredo, his father, or the Baron subsequently. Violetta's financial resources have been exhausted and the moment of her death is near. She receives a letter from the elder Germont saying that Alfredo seriously wounded the Baron in the duel and left France for a while, but the Baron has now recovered. Furthermore, Alfredo's father has relented and told his son of Violetta's sacrifice, and Alfredo will be coming to see her soon. However, Violetta fears that it is already too late, and she desolately prays to God "Ah! della traviata sorridi al desio!" as the words "This woman gone astray…Smile upon her…" appear in the subtitles. The mood is momentarily lightened by the sights and sounds of Mardi Gras revelers in the street, and Violetta's spirits are further lifted by Alfredo's arrival. Alfredo apologizes to her, and the film shows Violetta's happy dream of a time in the future when she, with her health restored, is walking with Alfredo in a marvelous wooded area, and together they approach a beautiful tree. Next, Alfredo's father, filled with remorse, enters Violetta's bedroom and begs her forgiveness. Then, with reconciliation complete, Violetta expends her last bit of strength in giving Alfredo a medallion containing her portrait and asking him to honor her memory by passing it on to the woman she expects he will someday marry. Violetta's dreadful pain disappears, and she feels intense joy for a few fleeting moments before she falls dead on the floor.

PlasmaCar Fever Takes Over Gilt Tech
One Friday morning in early February, the lives of many a Gilt technologist changed forever when a PlasmaCar showed up in our 2 Park office. Since that fateful Friday, a whole culture of PlasmaCar racing and competition has sprung up in both our NYC and Dublin offices–with official racing courses, official regulations, and official scoreboard, and official timekeepers (they wear silvery “marshal” badges). The friendly folks at PlasmaCar HQ heard about our activities and have helped us grow our fleet from one to five PlasmaCars. Man and woman, short and tall (as well as super-tall–like, 6'8" tall), adult and child-like adult, junior software engineer and Apache project committer, tech exec and whole-company exec: all of the above have been spotted (sometimes after hours) riding around, Plasma-style.
“PC Fever” has also spread to other Gilt departments–here are Tyler Thoreson (VP, Men’s & Home Editorial, Creative & Customer Experience) and Tracy Lomerantz Lester (Editorial Director, Women’s & Kid’s) helping to make our PlasmaCars famous:

The main focus of this course is to learn how to write computer programs using the Python 3 programming language. While you are learning Python, you are also learning about the constructs that underly most computer programming languages. You'll also learn how to design algorithms to solve problems, a key step in writing a program. Python is a way to express an algorithm in a way that lets a computer run it.
This is a programming course and not really a computer science course. This is a prerequisite for COSC 350 Data Structures & Algorithms, our first course in computer science.
Computer science is the study of computation—what can be computed and how to compute it. When a computer follows the steps of an algorithm coded in a programming language, the computer is doing computation. After this course you will be able to write programs in Python and be a better problem solver.
Using Python 3 to Solve Problems Using a Computer, 2nd edition by David Sykes and Dave Toth, Linus Learning, ©2020, ISBN 978-1-60797-910-4.
Most homework assignments, projects, and tests will be completed in Mimir. You will access Mimir Classroom through Moodle.
You need an account at Piazza. Accounts are free. Most communication outside of class will be done using our Piazza Q&A page.
The COSC 235A Moodle course page will have a link to Mimir and to Piazza. Scores for homework, exams, and projects will be recorded in Moodle. The cumulative grade shown in Moodle should reflect your final weighted score. If you notice a problem, please let me know and I will try to correct it.
We will use Zoom for class meetings. Portions of class meetings will be recorded and then be made available on the web. Note: It’s best to install the app on your computer and/or mobile device instead of using a browser.
The same meeting ID and password will be used for each class meeting all semester.
You need to install Python 3.8 on the computer you will use for assignments and projects this semester. The computer app is free.
Your grade for the course will be based on a weighted average of scores for quizzes, programming projects, and a paper/presentation. The usual grading scale applies: 93–100: A, 90–92: A-, 87–89: B+, 83–86: B, 80–82: B-, 77–79: C+, 73–76: C, 70–72: C-, 60–69: D, 0–59: F.
A final average will be calculated using two methods based on the weightings shown in the table. The higher of the two values will be mapped to a letter grade. Under Method #2, neither homework scores nor exam scores factor into the calculation.
| Component | Weight | |
|---|---|---|
| Method #1 | Method #2 | |
| Homework | 25% | 0% |
| Projects | 30% | 30% |
| Exams | 30% | 0% |
| Final exam | 15% | 70% |
| TOTAL | 100% | 100% |
Homework assignments help you to prepare for class and will usually consist of some reading in the textbook and some exercises (to be completed in Mimir). Homework is due before the start of the class for which it was assigned. Deadlines are enforced by Mimir.
Homework is graded. Partial credit will seldom be awarded for incorrect answers to homework problems. If you are struggling with a homework problem, post a question about it at Piazza. You are allowed to use any resources you find useful for completing homework assignments, including consulting other students in the class.
You will take two exams during the semester. The first will be administered after we cover Chapter 12. The second will be administered after we cover Chapter 19.
All exams will be given online (in Mimir). You may use your notes while you are taking the exam, but you may not use any other resources, including web resources and assistance from other people. Exams will be timed. You may select your start time, but you must complete the exam in the time allotted.
Projects play an important role in this course. Each of the projects will give you the opportunity to write a Python program that utilizes what you’ve learned so far. It is important that you start coding right after a project is assigned so you can get help if you have trouble getting started or fixing bugs.
The final exam will assess how well you reached the objectives for the course. The final exam will be given online (Mimir) and will have a time limit.
You may use the textbook and your notes from this class while taking the final exam. You may not use any other resources, including other people.
This class will run in accordance with a Blended Synchronous (Flipped Classroom). You will be expected to prepare for a class meeting by performing a variety of tasks, including:
You will be in one of three groups: A, B, or C. Groups A and B will attend class in-person one day a week and attend class remotely one day a week. Students in Group C will work fully remotely. Students in all groups should work synchronously unless there are extenuating circumstances.
During class meetings, in-person and remote students will work together in small teams to solve problems. That way in-person students can grab my attention to address issues.
Social distancing allows only half of the students to be in our classroom at one time. The first day of class will be completely remote. On the first day we will determine whether you are in Group A or Group B. Group C has already been set up. Some of you might join Group C temporarily if necessary. Note: I might revise group assignments during the semester.
Students in Group A will attend “in person” on Wednesday of the first week of classes and every other class meeting after that. Students in Group B will attend “in person” on Wednesday of the first week of classes and every other class meeting after that. The class on November 20, the Friday before Thanksgiving break, will be remote only. Check out the calendar.
We will use Zoom to support remote access. The links for class meetings and for office hours will be available in Piazza and Moodle. Portions of every class meeting will be recorded and made available online. The videos for a class meeting will be available in a Piazza post for that class.
 A facemask is not a substitute for social distancing. Do not modify the seating arrangement in the classroom.
Please evaluate your own health regularly. Do not attend class or other on-campus events if you are not feeing well. Seek appropriate medical attention for treatment of illness. A doctor's note concerning absences is not required.
You are expected to attend class sessions either in-person or remotely. The General Policy Regarding Attendance in the Wofford College Student Handbook makes you responsible for catching up on missed classes.
Class participation and active learning are important aspects of this class, so your engagement is critical to your success. However, I understand that sometimes you must miss examinations or other academic obligations affecting your grades because of illness, personal crises, and other emergencies. As long as such absences are not excessive (beyond two weeks of classes), I will work with you as best I can to help you succeed in the course. Contact me as soon as possible when such absences arise so we can make arrangements to get you caught up. This policy will not apply in the case on non-emergency absences.
If you will miss class on an “in person” day,
please post without any details (anonymously if you prefer) a follow-up
message to my Piazza post about the class
and tag your post with
open-seat
so that a student in the
other group can occupy your seat in the classroom.
If you are in the other group and would like that seat
then be the first to post in Piazza a claim for it.
If you will miss a class on a “remote” day, then let me know as soon as you can.
The final exam period is scheduled for 9:00-noon on Wednesday, December 9. You will take the final exam online in Mimir. You must complete the exam in the time allotted.
When attending class in person or remotely, you should dedicate your full attention to class activities. When attending in person, take notes and keep your laptop and other devices put away until we need them. When attending remotely, keep your video on and take notes. Give a holler if you have a question.
You must meet project deadlines. To submit a project late, you must contact me at least a day before the deadline to get an extension. Let me know how much more time you need. I will still expect you to submit the work you have completed so far even if you receive an extension.
Note: Any code you submit that contains syntax errors will receive a score of zero.
Post questions and comments about this course at Piazza. Feel free to respond to a question or to edit a response to a question. We are all learning together.
All questions about the course, including about projects, must be posted at the Piazza Q&A page. If you send me a question via email or via private post that should be posted publicly at Piazza, my reply will direct you to post your question publicly.
Do not post working code at Piazza. Do not include in a response either “fixed” code or a detailed description of how to change code to get it to work. It is okay to post non-working code.
I usually respond to email messages sent Sunday through Thursday within 24 hours—longer when sent on a Friday or a Saturday. I usually respond much sooner to Piazza posts since I have the Piazza app on my phone and receive notifications.
You can send me email messages for private matters, such as letting me know you will be absent or that you'd like to schedule a meeting. However, I prefer that you post a private message via Piazza.
Note: Anonymous Piazza posts are anonymous to classmates but not to me.
The Honor Code requires faculty, staff, and students to maintain a high standard of individual honor and integrity. Work represented as your own must be your own.
I encourage you to collaborate with others in the class—that is, help or get help from others. However, you may not write code for another student or provide code to copy. Doing any of these things is a violation Honor Code.
What is the distinction between collaboration and cheating?
During collaboration,
Ultimately, you must implement a solution to the problem yourself.
For some projects, you might be allowed to work with other students in the class. In this case, you are allowed to share all your work with your teammates. However, you are expected to do all of the work together. One student should not work without the others contributing.
Don’t cheat because you are up against a deadline. Start each assignment as soon as it is given. If you run into a glitch:
Mimir has extensive capabilities for detecting plagiarized Python code. When completing a project or a coding problem on an exam, don’t copy another student’s code or allow another to copy yours.
If you need accommodations, go to the Student tab in myWofford and investigate the Request Accommodations channel. I’ll make every effort to work with you.

hi i never took any unix and my professor for one of my classes want me to write a shell script i am wondering if anyone can help
i need to Write a script that outputs all lines in a file containing a specific keyword.
Uh, why do you need a script for this when it can be done using two commands?
cat file | grep keyword
Example: [13:00:32 residentbiscuit@zenalpha ~ ]$ cat .bashrc | grep if
if [ "$PS1" ]; then
if [ -z "$PROMPT_COMMAND" ]; then
if [ -e /etc/sysconfig/bash-prompt-xterm ]; then
if [ -e /etc/sysconfig/bash-prompt-screen ]; then
# if [ "$PS1" ]; then
# to your custom modification shell script in /etc/profile.d/ directory
if ! shopt -q login_shell ; then # We're not a login shell
if [ "$2" = "after" ] ; then
if [ $UID -gt 199 ] && [ "`id -gn`" = "`id -un`" ]; then
# Only display echos from profile.d scripts if we are no login shell
if [ -r "$i" ]; then
if [ "$PS1" ]; then
Also type "unix shell scripting tutorial for beginners" into youtube.
you dont even need youtube. there are hundreds of hits on google. also, i would specifiy a shell (more than likely bash) since thats what executes the shell script
