THE BOTTOM LINE
A MIDSUMMER NIGHT'S DREAM Written & Directed by Michael Hoffman Based on the play by William Shakespeare With Kevin Kline, Michelle Pfeiffer De Vargas PG-13 115 min
Have you ever had one of those dreams where things don't quite work the way they should, where stuff happens out of context and in the wrong places and the people don't all fit, but you still wake up feeling pretty good? That's the way it is with Michael ("Soapdish") Hoffman's take on "A Midsummer Night's Dream".
This is one of those conceptually reimagined Shakespearean productions, and while such adventures can work (Ian McKellan's "Richard III"), they run the risk of throwing the proceedings out of balance, and that's what happens here. Hoffman has set his version of the Bard's Athenian comedy in Tuscany, which causes a few problems, and he's updated it to the late 19th century (presumably to be able to throw in bicycles), which causes a few more. References to Athens seem a little strange in the setting, and a hundred years ago they were letting girls play girls' parts, which strains the logic of the "Pyramus and Thisbe" play-within-a-play casting.
The first clue that something may be amiss comes at the main title, which is overlaid with a wink-and-nudge note to the effect that corsets and high-button collars were still in fashion, but "the good news is that the bustle was on its way out, which made possible the use of that new-fangled invention, the bicycle." This doesn't set a Shakespearean tone, but it seems to embolden Hoffman to make a few other improvements on Shakespeare as he rolls along. The worst of these is a digression where, to give more prominence and pathos to Bottom, he has rude workmen spill red wine on the weaver's white suit, and then sends him home crestfallen to his apartment and his harridan wife (whom we've seen earlier looking for him and demanding in Italian "Where's that worthless husband of mine?") It becomes a virtual subplot, and it's of no great help to Shakespeare.
But the source material is magnificent, and the settings are beautiful, and the cast for the most part is up to the challenge. Dominic West as Lysander falls the shortest, but Calista Flockhart is a revelation as Hermia, and Stanley Tucci makes Puck a rascally animated cartoon that nicely fits the sprightly character. Rupert Everett is good as a quietly scheming Oberon, and Michelle Pfeiffer's beauty and talent do lovely things with Titania, though she occasionally seems to lose confidence and resort to acting flourishes.
The outstanding performance belongs to Kevin Kline, whose Bottom the Weaver radiates a rustic goodness and balances buffoonery with simple wisdom. Kline's language is effortless, his timing flawless, and his depth bottomless. He and Sam Rockwell (as the boy Thisbe) make a hilarious romp of the climactic play-within-a-play, which features that current comedy staple, the hurled dog, and might be retitled "There's Something About Thisbe".
The bottom line: despite its many flaws, it's still "A Midsummer Night's Dream", and it's still well worth seeing.

JavaScript code to efficiently generate a random (version 4) UUID per RFC 4122
Your random UUID is:
Reload this page to generate a new UUID.
References:


Foreign keys define a many to one connection, but every foreign key implicitly defines a reverse one to many connection as well. This can be exploited to define views and rules for aggregates.
Let's create a product type table.
create table product_type (
id integer,
name varchar,
constraint pk_id primary key (id));
There is a many to one mapping from products to product types. The reverse one to many
connection can be named via the reverse
keyword.
create table product (
id integer,
type_id integer not null,
name varchar,
constraint pk_id primary key (id),
constraint type foreign key (type_id) references product_type(id) reverse products);
Similarly, one transaction has exactly one product (and transitively product_type), and one product can have multiple corresponding transactions.
create table transaction (
product_id integer not null,
price float,
constraint product foreign key (product_id) references product(id) reverse transactions);
We can use the aggref
keyword to define an aggregated view of a one to many connection. This
subtable and its columns can be referred similarly to foreign keys via its name.
alter table product add aggref stats (
select count(1) as cnt, sum(price) as sum_price from transactions);
Similarly, we can build multiple levels of aggregations using a chain of one to many connections.
E.g. sum_price
here refers to the total price of all transactions of all products of any given
product_type.
alter table product_type add aggref stats (
select sum(stats.cnt) as cnt, sum(stats.sum_price) as sum_price from products);
We can define constraints for aggregates. Let's say we have a limited inventory for every product_type, we cannot have more than 5 transactions.
alter table product_type add constraint c_cnt check (stats.cnt <= 5);
Let's say we want to offer a discount but only if we sold enough products already. The price can only be less than 100 if we sold at least 1000 worth of that specific product type.
alter table transaction add constraint c_discount check (
price < 100 impl product.type.stats.sum_price >= 1000);
Let's add some records.
insert into product_type values (1, 'toy');
insert into product values (1, 1, 'doll'), (2, 1, 'truck');
insert into transaction values (1, 300.0), (1, 300.0), (2, 300.0);
We can query the aggregated view of one to many connections simply by using the name of the
aggref
table.
select name, stats.cnt, stats.sum_price from product_type;
name,cnt,sum_price
toy,3,900.0
Since the total price of toys is only 900, we cannot sell one for 50.
insert into transaction values (1, 50.0);
Constraint check c_discount failed.
But if we push the overall price to 1000, it works.
insert into transaction values (1, 100.0);
insert into transaction values (1, 50.0);
We have reached the overall number of 5 transactions for toys (via 5 successful and 1 unsuccessful inserts), so we cannot add more.
insert into transaction values (2, 50.0);
Referencing constraint check product_type.c_cnt failed.
The parent
keyword can be used to refer to the source table in an aggref
.
alter table product add aggref truck_stats (
select count(1) as cnt, sum(price) as sum_price from transactions where parent.name = 'truck');
Now the aggregated table is only computed for "trucks".
select name, truck_stats.cnt, truck_stats.sum_price from product;
name,cnt,sum_price
doll,0,null
truck,1,300.0

Man Utd handed huge injury boost by six injured stars including Shaw & Bailly
Manchester United received a host of injury boosts on Wednesday as Eric Bailly, Luke Shaw, Axel Tuanzebe, Nemanja Matic, Diogo Dalot and Timothy Fosu-Mensah all took part in training.
Ole Gunnar Solskjaer took charge of training at Carrington ahead of United’s Premier League clash with Sheffield United on Sunday.
The United boss welcomed back some of his players on international duty and several first-team stars who have been struggling with injuries.
The club confirmed defensive trio Bailly, Fosu-Mensah and Dalot were back in training, but conducted their own session away from the main group.
Bailly and Fosu-Mensah are yet to play this season while Dalot has not featured for United since October.
While that defensive trio continued their recovery, Matic, Shaw and Tuanzebe were able to take part in the main session.
Advertisement Advertisement
Matic has barely played this season as he has struggled to break into Solskjaer’s team, while Shaw has been nursing a hamstring issue and Tuanzebe a hip problem.
While Matic has been continually overlooked by Solskjaer, he may get a recall due to an injury to Scott McTominay.
The Scotsman did not train with the group and was forced to pull out of international duty this month due to an ankle injury.
Ashley Young also trained and he will be available for selection against Sheffield following his suspension for United’s previous game.
United are nine points off fourth place, with Sheffield flying high in fifth place, two spots above the Red Devils.


Blimey! That was a bloody awful start to the year.  Only in the past few days do I at last seem to be recovering my pep, or what passes for pep in these parts.
It now behooves me to set Hooting Yard back on course after a whole month of silence. To this end, I have devised a foolhardy scheme, a planned series of interconnected pieces o' prose, none of which I have yet written. We shall see how that pans out in the coming weeks.
Meanwhile, I ought to draw to your attention the annual fundraiser at ResonanceFM, in the hope that you will give generously. You lot may be particularly interested in bidding for this year's Hooting Yard auction item, a unique bespoke paperback to be issued in an edition of one.
I shall try to be back tomorrow, with some new prose …

What is the Smart Cultural Triangle Precinct?
The SCTP is the area between the Central Market, Tai Kwun (former Central Police Station complex), and PMQ (former Police Married Quarters) in the Central District of Hong Kong. The Institute for Sustainable Urbanisation (ISU) started the SCTP project in 2008 as an area-based conservation project aimed at preserving the historic and cultural heritage of this unique region.
Numerous conservation efforts have already take place in the area, including the preservation of the Tai Kwun and PMQ. The Central Market's revitalization plan is still in progress, and it aims to be completed by 2020.
Historic Sites
Cultural Triangle Location
The cultural triangle is located conveniently in the Central district, on Hong Kong Island. All three sites are within a ten minute walk of each other, and the area is bisected by the scenic Central–Mid-Levels escalator. The Central Market is a quick five minute walk from Central Station west along Des Veoux Road Central.
The SCTP is also bisected by the Central–Mid-Levels escalator, the longest outdoor covered escalator system in the world. This transport system/tourist attraction is lined with shops, restaurants, and markets, making it a nexus of Hong Kong culture.
About this Website
This site was made by a group of students from Worcester Polytechnic Institute who worked with the ISU to further the preservation, development, and promotion of the SCTP.

FATHER'S DAY A film review by Michael Redman Copyright 1997 Michael Redman
** (out of ****)
This film has just about everything going for it. Writers Lowell Ganz and Babaloo Mandel are responsible for two of the wittiest comedies of recent years: "City Slickers" and "Parenthood". Producer/director Ivan Reitman has "Ghostbusters" to his credit. Some of the supporting cast are well respected (Nastassja Kinski, Julia Louis-Dreyfus of "Seinfeld" fame). It's a nice touch that a film entitled "Father's Day" is released on Mother's Day weekend.
But the real reason that it looks great is the inspired teaming of Robin Williams and Billy Crystal, two of the top comedic actors working today. You can easily imagine them bouncing off of each other with quips and ad libs and movie-goers want to get in on some of the fun. The scene in the previews where Crystal is trying to explain who Lou Gehrig is ("The guy who died of Lou Gehrig's Disease." "Wow! What are the odds of that?") is inspired.
Prepare for a major disappointment.
Based on the 1984 French "Les Comperes", the movie is an odd couple buddy road trip film. Happily married Collette (Kinski) is disparate to find her runaway 16 year old son. Being a friendly sort 17 years ago, she knew both Jack (Crystal) and Dale (Williams) in the Biblical sense. Calling and telling each of them that they are the father of her son, she begs them to find him.
Of course both of the fathers accidentally discover the other and pair up to find missing Scott (Charlie Hofheimer). Their journey takes them from a tough auto repair shop to a tough rock tour via encounters with tough drug dealers.
Jack is a sophisticated LA lawyer with a talent for head-butting. Dale, a San Francisco poet with a history of suicide attempts, bursts into tears at the slightest provocation. Both actors are perfectly suited to their roles and pull them off with style.
It just doesn't work. The story is old hat. Most of the shticks have been done before and often. The middle-aged man at a rock concert was funnier on the "Simpsons". With a few exceptions, the jokes fall flat on their faces even though Crystal and Williams do their best to grab them out of the muck.
Part of the problem is that Hofheimer is remarkably uninspiring as the 16-year-old with too many hormones and too little money. Kinski is adequate but nothing special as she exhibits none of the steaming sexuality that has always been her forte and could have been used in a role that is defined by her irresistibility. Louis-Dreyfus does better with Jerry, George and Kramer or perhaps she needs a project with genuinely humorous moments.
Crystal and Williams __must__ have been a hoot on the set, but unfortunately there's not much evidence of that on the screen.  The hotel shower scene is occasionally hilarious, but you've seen it before. I get the feeling that the better movie was left on the cutting room floor as outtakes.
If this were ranked on a "Living Up To Potential" scale, it would rate a Zero.

HealthCheck
Java Chassis had support HealthCheck since 1.0.0-m1.
Introduction
Microservice always depend on many middlewares like database, message queue etc. Also depend on other microservices. When microservice is unavailable, may caused by database, we need record details into log file or show details on dashboard: database disk had full? database accress right had invalid? or database accress user and password had changed? not only a DOWN state, details can help dev ops find where is the problem and solve it faster.
HealthCheck provide an extensible mechanism, user can create custom check point in order to probe whether the core dependencies are available, if any one is unavailable, report the details:
How to use
Implement custom HealthCheck
It is easy to implement Java Chassis HealthCheck, implements from org.apache.servicecomb.foundation.metrics.health.HealthChecker
interface and override these methods:
| Method Name | Description |
|---|---|
| getName | Return the name of HealthChecker, please make sure do not duplicated, otherwise the results of same name will merged |
| check | Concrete implementation of Check logic |
Example:
public class MySqlHealthChecker implements HealthChecker {
@Override
public String getName() {
return "mysql";
}
@Override
public HealthCheckResult check() {
//add your health check code here
Connection connection = null;
try {
connection = DriverManager.getConnection("jdbc:mysql://localhost:3306/test_db?useSSL=false", "root", "pwd");
return new HealthCheckResult(true, "local mysql health check", "");
} catch (SQLException e) {
LOG.error("Cannot connect the localhost mysql. ", e);
return new HealthCheckResult(false, "local mysql health check", e.toString());
} finally {
if (connection != null) {
try {
connection.close();
} catch (SQLException e) {
LOG.error("Close connect the localhost mysql error. ", e);
}
}
}
}
}
We use SPI to load it, create an new file named org.apache.servicecomb.foundation.metrics.health.HealthChecker
under esource/META-INF/services
folder, write class name of your HealthChecker into it, like:
org.apache.servicecomb.samples.metrics.extendhealthcheck.MySqlHealthChecker
Verify HealthCheck
After microservice startup, HealthCheck will publish use Rest endpoint, the publish address is same as servicecomb.rest.address
, if had configure in microservice.yaml
like:
servicecomb:
rest:
address: <IP_ADDRESS>:8080
We can get HealthCheck final result by accress http://localhost:8080/health , also can get detail results by accress http://localhost:8080/health/detail .
NOTE:
- The implementation of Rest publish is in metrics-core, so need import this dependency;
- The result of /health is the final result of all HealthCheckers, true or false, if healthy result of any HealthChecker return false, then this value will false.
Other Reference
We had provided a sample at samples/metrics-extend-healthcheck.


Corona Familiar
Despite being so objectionable in raw form that it requires a lime to drink, Corona Extra/Light (with a lime) is one of my favorite summertime treats. There's a reason the Corona's marketing is beach-centered — the beer and warm weather suit each other.
There's also a reason that Corona Extra is one of the few beers to come in a clear bottle, and it doesn't speak well of Corona's quality. Light damages beer. This is one reason cans are actually better than bottles, and the sole reason that only an already heinous beer gets stored and shipped in clear or green bottles. You can't skunk a beer, looking at you Rolling Rock and Heineken, that's already skunked. They even take the time to put Schlitz Malt Liquor in a brown bottle, for goodness sake.
As a fan of old familiar Corona, I was slightly intrigued by the introduction of Corona Familiar. The brown bottle lets you know that at least this beer is good enough to deserve the same light-deflecting brown bottle as the Milwaukee's Best family. Although, to be fair, Milwaukee's Best in bottle-form only exists to help the government's intelligence agency update their terror watch list — if you must buy Beast, please, just buy it by the case of cans as God intended.
I guess the Corona marketing team was looking to make use of the "Familiar" title, so they bill this as a beer "best made to be shared."  The best beers are made for you to consume and then recommend to your friends. The best beers are not made to be put into 32-ounce bottles, like Corona Familiar, and passed around at the party. That's what the worst beers are for.
Slight intrigue in Corona Familiar did not give way to high expectations, and I'm happy to report those expectations were mostly met. It's a Corona that doesn't need a lime. And… that's about it. If it's summer and I must have a Corona I'm sticking with an old, familiar friend in a clear bottle. Unless I can't find a lime. In that case, I'll grab a Dos Equis Amber. Which, come to think of it, is better with a lime too. Sensing a trend, here, beers of Mexican descent.

Description: Evolve-a-Robot is an interactive evolutionary robotics simulation. The project has two goals. The first is to expose K-12 students to evolution and evolutionary computation using an engaging and fun platform. Evolve-a-Robot does this by visualizing the evolution of robotic cars with an easy-to-use interface. And second, to expose enough of the adjustable parameters (i.e. genetic operators, and evolutionary configuration) to make the simulation useful for teaching evolutionary algorithms to undergraduate students.

Description: The Biolume art exhibit is meant to captivate and inform the general public. The installation will comprise approximately 150 culptural robots that 'evolve' to better interact with patrons. Through interaction with the public, Biolume robots gain energy and are preferentially selected for reproduction to 'replace' less fit neighbors.


| PostgreSQL 9.0.10 Documentation | ||||
|---|---|---|---|---|
| Prev | Up | Appendix F. Additional Supplied Modules | Next |
The sslinfo module provides information about the SSL certificate that the current client provided when connecting to PostgreSQL. The module is useless (most functions will return NULL) if the current connection does not use SSL.
This extension won't build at all unless the installation was configured with --with-openssl.
ssl_is_used() returns boolean
Returns TRUE if current connection to server uses SSL, and FALSE otherwise.
ssl_client_cert_present() returns boolean
Returns TRUE if current client has presented a valid SSL client certificate to the server, and FALSE otherwise. (The server might or might not be configured to require a client certificate.)
ssl_client_serial() returns numeric
Returns serial number of current client certificate. The combination of certificate serial number and certificate issuer is guaranteed to uniquely identify a certificate (but not its owner — the owner ought to regularly change his keys, and get new certificates from the issuer).
So, if you run your own CA and allow only certificates from this CA to be accepted by the server, the serial number is the most reliable (albeit not very mnemonic) means to identify a user.
ssl_client_dn() returns text
Returns the full subject of the current client certificate, converting character data into the current database encoding. It is assumed that if you use non-ASCII characters in the certificate names, your database is able to represent these characters, too. If your database uses the SQL_ASCII encoding, non-ASCII characters in the name will be represented as UTF-8 sequences.
The result looks like /CN=Somebody /C=Some country/O=Some organization.
ssl_issuer_dn() returns text
Returns the full issuer name of the current client certificate, converting
character data into the current database encoding. Encoding conversions
are handled the same as for ssl_client_dn
.
The combination of the return value of this function with the certificate serial number uniquely identifies the certificate.
This function is really useful only if you have more than one trusted CA certificate in your server's root.crt file, or if this CA has issued some intermediate certificate authority certificates.
ssl_client_dn_field(fieldname text) returns text
This function returns the value of the specified field in the certificate subject, or NULL if the field is not present. Field names are string constants that are converted into ASN1 object identifiers using the OpenSSL object database. The following values are acceptable:
commonName (alias CN) surname (alias SN) name givenName (alias GN) countryName (alias C) localityName (alias L) stateOrProvinceName (alias ST) organizationName (alias O) organizationUnitName (alias OU) title description initials postalCode streetAddress generationQualifier description dnQualifier x500UniqueIdentifier pseudonym role emailAddress
All of these fields are optional, except commonName. It depends entirely on your CA's policy which of them would be included and which wouldn't. The meaning of these fields, however, is strictly defined by the X.500 and X.509 standards, so you cannot just assign arbitrary meaning to them.
ssl_issuer_field(fieldname text) returns text
Same as ssl_client_dn_field
, but for the certificate issuer
rather than the certificate subject.

Titanic (1997)
Grade: 55
"Titanic" has the highest box office gross of all time: over one billion dollars. It is also the most expensive film ever made, at two hundred million dollars. And it was one of the most successful films ever at the Academy Awards, winning eleven Oscars. So, what is wrong with this picture? Plenty.
Has a film ever before received fourteen Academy nominations without one for the screenplay? While direction, casting and cinematography are important, the key component of a film's quality is usually the script. The 'Titanic' script is burdened with lame and unlikely dialogue between the romantic leads (e.g. "I'll never let go") and loaded with one-dimensional characters.
While the 'Titanic' story lends itself to class conflict, this feature is over-emphasized. The 'rich' characters are either half-embalmed snobs or despicable jerks, excepting only gregarious hero Molly Brown (Kathy Bates) and spoiled, passionate love interest Rose (Kate Winslet).
The film begins with a current day Titanic salvage operation. For dramatic purposes, Rose (Gloria Stuart), now 101 years old, is brought on board the salvage ship. She tells her increasingly dubious story to the rapt crew.
Rose is pressured by her mother to wed abusive Cal (Billy Zane). Her friends are so shallow, and Cal such a jerk, that Rose is driven to tears and makes a suicide attempt. With 2200 passengers, you'd think that more than just Jack would be on deck to save her, and he doesn't look strong enough to pull her back onboard. Of course, they soon have a romance, which of course is disapproved of by Mom and the surprisingly jealous fiance.
The film is late in its second hour before the Titanic finally gets around to hitting the iceberg. "Titanic" then begins to lift scenes from the vastly superior "A Night to Remember" from 1958, mixing them in with long sequences of Rose and Jack repeatedly rescuing each other from deepening and near-freezing water.
The film ends with more silliness. Survivor Zane is unable to find Rose during the long voyage to America, despite Rose's mother being on board (conveniently, her character disappears during this time). Rose doesn't find the blue diamond in her coat pocket until she reaches New York! There is also a dream sequence which has Jack and Rose enter the Titanic's gigantic ballroom to incongruous massive applause from the well-to-do guests, who were so maligned for their shallowness in the film's first half.
Since director James Cameron is at his best during action scenes, "Titanic" can be entertaining at times. The story is dramatic, and the special effects are convincing. But given the dubious script, characters and events, "Titanic" may be the most over-praised film of our generation.

Status: Passed V11 March 89

Problem Description:
It is unclear whether various diagnostics issued by the compiler are
supposed to be true errors and warnings, or merely messages.
In some implementations, COMPILE-FILE handles even serious error
situations (such as syntax errors) by printing a message and then
trying to recover and continue compiling the rest of the file, rather
than by signalling an error. While this user interface style is just
as acceptable as invoking the debugger, it means that a normal return
from COMPILE-FILE does not necessarily imply that the file was
successfully compiled.
Many compilers issue warnings about programming style issues (such as
binding a variable that is never used but not declared IGNORE).
Sometimes these messages obscure warnings about more serious problems,
and there should be some way to differentiate between the two. For
example, it should be possible to suppress the style warnings.
Also, neither CLtL nor issue RETURN-VALUES-UNSPECIFIED states what the
return value from COMPILE-FILE should be.
Proposal COMPILER-DIAGNOSTICS:USE-HANDLER:
(1) Introduce a new condition type, STYLE-WARNING, which is a subtype
of WARNING.
(2) Clarify that ERROR and WARNING conditions may be signalled within
COMPILE or COMPILE-FILE, including arbitrary errors which may
occur due to compile-time processing of (EVAL-WHEN (COMPILE) ...)
forms or macro expansion.
Considering only those conditions signalled -by- the compiler (as
opposed to -within- the compiler),
(a) Conditions of type ERROR may be signalled by the compiler in
situations where the compilation cannot proceed without
intervention.
Examples:
file open errors
syntax errors
(b) Conditions of type WARNING may be signalled by the compiler in
situations where the standard explicitly states that a warning must,
should, or may be signalled; and where the compiler can determine
that a situation with undefined consequences or that would cause
an error to be signalled would result at runtime.
Examples:
violation of type declarations
SETQ'ing or rebinding a constant defined with DEFCONSTANT
calls to built-in Lisp functions with wrong number of arguments
or malformed keyword argument lists
referencing a variable declared IGNORE
unrecognized declaration specifiers
(c) The compiler is permitted to signal diagnostics about matters of
programming style as conditions of type STYLE-WARNING. Although
STYLE-WARNINGs -may- be signalled in these situations, no
implementation is -required- to do so. However, if an
implementation does choose to signal a condition, that condition
will be of type STYLE-WARNING and will be signalled by a call to
the function WARN.
Examples:
redefinition of function with different argument list
calls to function with wrong number of arguments
unreferenced local variables not declared IGNORE
declaration specifiers described in CLtL but ignored by
the compiler
(3) State that both COMPILE and COMPILE-FILE are permitted (but not
required) to establish a handler for ERROR. For example, they
might issue a warning, and restart compilation from some
implementation-dependent point in order to let the compilation
proceed without manual intervention.
(4) Specify that COMPILE and COMPILE-FILE return three values. The first
value from COMPILE is not changed by this proposal. The first value
from COMPILE-FILE is the truename of the output file, or NIL if the
file could not be created.
The second value is NIL if no compiler diagnostics were issued, and
true otherwise.
The third value is NIL if no compiler diagnostics other than style
warnings were issued. A non-NIL value indicates that there were
"serious" compiler diagnostics issued, or that other conditions of
type ERROR or WARNING (but not STYLE-WARNING) were signalled during
compilation.
Rationale:
Introducing the STYLE-WARNING condition allows handlers to distinguish
between potentially serious problems and mere kibitzing on the part of
the compiler.
The second and third return values from COMPILE and COMPILE-FILE give
some indication of whether there were serious problems encountered in
compiling the file.
Current Practice:
No implementation behaves exactly as specified in this proposal.
In VaxLisp, COMPILE-FILE handles most compile-time errors without
invoking the debugger. (It gives up on that top-level form and moves on
to the next one.) Instead of signalling errors or warnings, it simply
prints them out as messages.
In Lucid Common Lisp, COMPILE-FILE invokes the debugger when it encounters
serious problems. COMPILE-FILE returns the pathname for the output file.
Symbolics Genera usually tries to keep compiling when it encounters errors;
so does Symbolics Cloe.
On the TI Explorer, the compiler tries to catch most errors and turn
them into warnings (except for errors on opening a file), but the user
can change special variable COMPILER:WARN-ON-ERRORS to NIL if he wants
to enter the debugger on an error signalled during reading, macro
expansion, or compile-time evaluation. The true name of the output
file is returned as the first value. A second value indicates whether
any errors or warnings were reported.
IIM Common Lisp's compiler handles errors using a resignalling mechanism
similar to what is described here.
Cost to implementors:
The cost to implementors is not trivial but not particularly high. This
proposal tries to allow implementations considerable freedom in what
kinds of conditions the compiler must detect and how they are handled,
while still allowing users some reasonably portable ways to deal with
compile-time errors.
Cost to users:
This is a compatible extension. This proposal may cause users to see
some small differences in the user interface to the compiler, but
implementations already vary quite widely in their approaches. Some
users will probably have to make some minor changes to their code.
Adding the STYLE-WARNING type may cause conflicts with programs
already using that name.
Benefits:
Users are given a way to detect and handle compilation errors, which
would simplify the implementation of portable code-maintenance
utilities. The behavior of the compiler in error situations is made
more uniform across implementations.
Discussion:
The issue of whether the compiler may print normal progress messages
is discussed in detail in a separate issue, COMPILER-VERBOSITY.
Explicit calls to ERROR don't really justify warnings to be signalled
at compile-time, but we assume implementors have some common sense
about when it's appropriate to do so.

Sapir–Whorf hypothesis) says that the languages we speak influence the way we think. I argue this applies to programming languages too. However, key differences between spoken languages and programming languages enable us to adapt and shift our ways of thinking more fluidly as we learn programming languages than as we learn spoken languages. We can and should leverage these differences to grow individually as programmers and further advance our favorite programming languages.


MIGHTY JOE YOUNG A film review by Steve Rhodes Copyright 1998 Steve Rhodes RATING (0 TO ****): ** 1/2
If you find those irritating car burglar alarms that go off for no reason whatsoever to be the equivalent of fingernails across a blackboard, the movie MIGHTY JOE YOUNG suggests the perfect solution. You need to ask your spouse for a 2,000-pound gorilla for Christmas. Being close ancestors to Homo sapiens, big apes hate those loathsome alarms as much as we do, but they can do something dramatic about it. And if you're an overgrown ape like Joe, the film's humongous star, all you need to do is stomp and sit on the screeching car a few times in order to turn it into raw recycling material.
Ron Underwood, who has given us comedies as brilliant as CITY SLICKERS and as dreadful as SPEECHLESS, directs this remake of the 1949 movie MIGHTY JOE YOUNG. Besides the realistic looking gorilla, the stars of the movie are A SIMPLE PLAN's Bill Paxton as Gregg O'Hara, a conservationist, and CELEBRITY's Charlize Theron as Jill Young, Joe's companion and surrogate mother.
The movie opens years earlier when Joe and Jill are both youngsters. Poachers come into the animal preserve where Joe lives with his mother and Jill with hers. On a dark and misty night, the poachers kill both mothers. Jill hides with Joe then and for years afterwards. The sweet image of them nestled together, while hiding in the heavy brush, is one of many such tender moments in the picture.
The gorgeous Charlize Theron takes care of Joe like a mother of a super-economy-sized toddler. Their favorite game together is hide-and-seek, which takes on a whole new meaning when one of the players is Joe's size. Joe solves this with a little kid's trick of making himself invisible by covering his eyes with his hands. The childlike innocence of these game scenes and the one of Jill is being cuddled while singing Joe to sleep are the movie's best.
The formulaic plot with cartoon-cutout villains is the story at its worst. As Strasser, Rade Serbedzija plays the cliched leader of the bad guys as he did previously in THE SAINT. Little Joe chews off a finger and a thumb from Strasser's hand in the beginning of the movie. Throughout the movie, the camera loves to stare at the hand with the missing digits. This is just one of the cheap tricks that the director falls back on when he can't think of anything else to do. Another is the slapstick action with Joe tossing large items like jeeps around as if they were kitty toys.
When Charlize Theron smiles at Joe, he obeys. The men in the audience will have no problem believing this. Most would be happy to follow her commands. The chemistry between Joe and Jill is excellent, as is the love interest between Gregg and Jill.
The problem with the movie, most of which happens when Joe is brought back to LA to protect him from poachers, is that the entire story can easily be reduced to 2 parts. The gorilla is either growling, which may scare the daylights out of some kids, or playing, which will delight everyone. The story itself is so thin, involving the evil Strasser's attempt to steal Joe for his body parts, that it keeps dragging.
The movie tries to have a surprising ending but can't quite bring itself to do it. In ends nicely enough but in the same formulaic spirit of the rest of picture. Even so, you can't help but have a soft spot in your heart for a film with a lovable ape and two charming human leads. The three of them are better than the movie that they are in.
MIGHTY JOE YOUNG runs too long at 1:54. It is rated PG for violence and would be fine for kids around 8 and up, although some younger kids may be able to handle it.
My son Jeffrey, age 9, thought the movie was sort of "so-so," and gave it **. He complained that it should have been rated PG-13 since he found some of it scary.

UFC’s Conor McGregor pleads guilty to Dublin pub attack, fined over $1000
by Lewis MckeeverEarlier today, Conor McGregor appeared in court and pled guilty to assault for punching a man at a pub in Drimnagh, Ireland earlier this year.
McGregor, the former UFC featherweight and lightweight champion, is reported to have apologized to the victim, Desmond Keogh, for his actions but Keogh did not attend the court hearing. ‘The Notorious’ was fined $1,116.68 and promised to never repeat his actions.
“What I did was very wrong and I’d like to apologize again to the injured party and today before the court and assure you that nothing of this nature will happen again,” McGregor said at the court hearing in Dublin, per The Journal.
Although the victim was not present in court, it’s reported that Keogh accepted McGregor’s apology but chose not to release a formal statement.
McGregor, 31, is expected to return to the UFC in January to face either Donald Cerrone or Justin Gaethje. The Irishman hasn’t fought since his headlining lightweight bout with Khabib Nurmagomedov at UFC 229, which saw McGregor submitted in the fourth round with a neck crank.


utility.useCpuFor(100) // a computation of 100ms
utility.useCpuFor(50) // a computation of 50ms
utility.useCpuFor(50) // a computation of 500ms

let list = [20, 40, 20, 30, 50, 100, 30, 100, 100, 30, 40, 100];
for (let i = 0; i < list.length; i++) {
utility.useCpuFor(list[i]);
}
The above code produces an event-loop lock for 1 seconds, and thus prevents the browser to do any other thing (e.g., render the animation on the page).
In order to remove the event-loop lock without too many changes in the code, we propose to use the yield syntax in combination of a library function yieldControl
.
The yieldControl
function takes in input a generator with the work to be executed and a callback function to be executed at the end of the computation.
We can transform the above intensive CPU code with the following by adding the yield command every time we want to release the event-loop:
utility.useCpuFor(100) // a computation of 100ms
yield;
utility.useCpuFor(50) // a computation of 50ms
yield;
utility.useCpuFor(50) // a computation of 500ms
yield;
utility.useCpuFor(100) // a computation of 20ms
yield;
utility.useCpuFor(40) // a computation of 20ms
yield;
// A CPU intensive computation on an array
let list = [20, 40, 20, 30, 50, 100, 30, 100, 100, 30, 40, 100];
for (let i = 0; i < list.length; i++) {
utility.useCpuFor(list[i])
yield;
}
In the rest of the page there a simple demo, to show how does it work and perform.
The Without YieldControll
button run the first kind of code, instead of the With YieldControl
button run the second version of the code.
It is possible to see that the first version take exactly a seconds to run but block the gif animation.
Instead, the second version, the one using YieldControl
, take more seconds to run but do not block the gif animation.
Indeed, the yieldControll version interpolates the computation with the other task that the browser usually does.

Proof of lemma 29.4
Lemma 29.4 states that if is the standard form of a linear program and B is a set of variables, the slack representation of the same would be uniquely determined.
It is to be proved that the same holds for and.
Proof of Identical Slack Form
It can be proved that for and, the slack form can be determined uniquely, as below.
Consider the proof of lemma 29.4 (refer to section 29.3 of the textbook). For the basis of contradiction, consider the two slack forms for the same set of the basic variables. Suppose that the set of basic variables is B. There must be an identical set of non-basic variables and that is.
Now, the slack form for both of the identical and the non-identical variables can be written as:
First slack form:
… … (6)
… … (7)
Now, replacing the values as and, the second slack form of the same would be as:
… … (8)
… … (9)
Now, subtract the equation (8) from (6) and the equation (9) from (7). This will yield the following result:
This can be further written in the following form:
… … (10)
Now, compare the equation (10) with the one that is given in the lemma 29.3 (refer to the section 29.3 of the textbook).
The comparison yields the following simulations:
The lemma in 29.3 says that the value of should be 0 and that makes the following to happen:
That is,
According to this result, the following can be speculated. The left hand side of the equation (6) and (8) is equal. This means the right hand side of the equation would obviously be equal to each other.
Now, the first term of the right hand side of equation (6) and equation (8) have already been proved to be equal to each other. So, the second term of each one of them should be equal to the each other.
That leads to the result:
That would mean:
So, this proves that for the two slack forms if,
Then, the slack form can be uniquely determined.
Simplex Procedure
Effect of call to PIVOT on the value of v :
Consider the smallest subscript rule which is applied to prevent the cycling. Considering the cycles of dictionaries and denote by the symbol.
It is the case of degeneracy of cycle which identifies the same basic viable solution. In the case of pivoting of and the variables may leave or enter. But as the leaving variable is in the basis of, whereas the entering variable does not lay in it, so the leaving variable enters at least once in the basis of the cycle.
Hence it can be concluded that in the cycle the variables, which can enter or leave the cycle at least once in the cycle, exist. These variables are termed as the fickle variables.
Any variable which either leaves or enter the cycles are termed as the fickle variables. And if these variables are non-basic then the values associated with these basic feasible solution is zero.
As the basic viable solution which is identified in the cycle always remains fixed throughout and the fickle variables holds the value as 0 in the cycle.
So consider the dictionary which is associated as,
In the above equation
= leaving variable and
=entering variable
As the is among the fickle variable so and
Consider be a dictionary in which there is as entering the root.
It is visibly seen that the entire dictionary in the cycle signifies the same basic feasible solution so the value of z remains constant.
Now as the value at the left hand side of the equation remains constant, it is obvious that the value of the equation at the right side would remain constant.
There are two terms at the right hand side. The value of the second term would remain constant because if any of the individual variables go up or down, the addition of the set would always be a constant. If that happens, there remains only one more of the terms.
Intuitively, the value of the other term would always be constant and that is v.
So, the value of v would never be decreased when PIVOT is invoked in the line 12 of the procedure.
The input linear program to the PIVOT procedure is of the form.
The following is the PIVOT procedure:
PIVOT
1 //compute the equation’s coefficient for the new basic variable
2 Consider to be a new matrix
3 //calculate the value of
4
5 //loop for all the values of j that are a part of N except {e}
6 for each
7 //calculate the value of
8
9 //update the value of
10
11 //calculate the values for constraints
12 //loop for all the value of i that are a part of B except {l}
13 for each
14 //calculate the value of
15
16 //loop for all the values of j that are a part of set N except {e}
17 for each
18 //calculate the value of
19
20 //update the value of
21
22 //calculate the new version of objective function and calculate the value of
23
24 //loop for all the values of j that are a part of set N except {e}
25 for each
26 //calculate the value of
27
28 //update the value of
29
30 //calculate the new non-basic variables
31
32 //calculate the new basic variables
33
34 //return the new slack from of the linear program
35 return
The similarity in the input and the output slack form:
The PIVOT procedure takes slack form of the linear program as input.
The input is represented by the tuple , where l is the index of leaving variable x1 and e is the index of entering variable.
The procedure generates and returns the tuple which is of the form.
Show that the slack forms given to the PIVOT procedure, and those returned by it, are equivalent. Consider the following three conditions:
denotes the solution which is returned after the call.
1. for each j that belongs to.
2.
3. for each.
It is enough to prove that the above three statements hold, in order to prove that the slack forms given to the PIVOT procedure, and those returned by it, are equivalent.
The first statement holds since the basic solution is available which always sets all the non-basic variables to zero.
In the calculation process, when all the non-basic variables are set to zero in the given constraints, then,
Since , line 4 of the PIVOT procedure replaces with the new value to get the new slack form as follows:
Here,
Hence, the second statement is proved.
and
Hence, the three conditions hold.
Therefore, the slack form that procedure PIVOT takes as input, and the slack form that the procedure returns, is same.
Optimal value: Optimal value refers to the desired value of the linear program. In the current case, the optimal value refers to maximizing the problem.
• A problem is a standard maximizing problem, if it has the following characteristics:
• The objective is to find the maximum of the objective function
• All the variables are non-negative
• All the constraints are of linear form and less than equal to 0.
The given problem satisfies all the above characteristics, so it is a standard maximizing problem. To solve it, the following steps are followed:
• Convert the Linear program to a system of linear equations.
• Create the table for the above system of linear equations.
• If pivoting is possible, then proceed to create new tables as long as pivoting can be done.
The final table gives the optimal solution.
Step 1: Convert the linear problem to a system of linear equations:
The characteristic that each constraint is less than equal to 0 helps to convert the given problem into a system of linear equations. This is done by introducing slack variables. The slack variables are added to the inequalities to convert them into equalities.
Even the objective function which is to be maximized is presented here.
The following is the system of linear equations formed:
In the above, the slack variables are.
Step 2: Create table for the system of linear equations:
The table for the system of linear equations is the following:
From the above table, it is observed that there are negative values in the last row.
So, pivoting is possible. By the process of pivoting, the solution keeps improving until no more pivoting can be done.
Step 3: Pivoting:
Pivoting involves first finding out the pivot using the following method:
• Find out the pivot column.
• Find out the pivot.
Pivot column: In last row, find out the value (except in the Ans column) which is negative and has the highest magnitude. The column that contains this element is called the pivot column. So, the pivot column is column.
Pivot element: Pivot element has the property of being a values greater than 0. At this point there are two values 1 and 2 which are greater than 0. To break the tie, find out the test ratio.
Test Ratio: It is the ratio of the value in Ans. Column and the candidate for the pivot element.
The table bellows displays the test ratio of each candidate.
It is found out that the test ratio for both the candidates is same. So, any one of it can be chosen as the pivot element. Here 1 in row1 has been chosen as the pivot element.
After finding out the pivot element, the process of pivoting involves performing row operations on the table to create a new table where the pivot column has all values equal to zero except the pivot element.
The following row operations have to be performed:
The new table is the following:
From the above table, it is observed that further pivoting is possible because the last row of the table has a negative value. It is the pivot column. There is only one positive value in that column which is 3. So, the pivot element becomes 3. It has been clearly shown in the table above.
Now perform the required row operations to make the different values of the pivot column zero except the pivot element itself.
The row operations to be performed are the following:
The new table is the following:
There are no negative values in the last row of the table above. Hence, there is no more pivoting to be done. The optimal solution can be found from this table as given in the next step.
Step 4: Calculate the optimal solution:
Every table shown till now has a basic solution associated with it but all those solutions can be improved further to obtain the optimal solution by pivoting. In the previous step, a stage is reached from where no more pivoting is possible, so, this final table gives the optimal solution.
To find the optimal solution, the following steps are followed:
• Find out the cleared column.
• Find out the active variables and inactive variables
• Find out the value of the active variables.
Cleared column: The columns those contain only one non-zero and all others being zero are called cleared columns. In the above table, the cleared columns are the columns under.
The variables are called the active variables and the rest are the inactive variables.
Find the ratio of. This gives the value of the variable.
The following table shows the cleared columns, active variables and the ratio.
From the above table, optimal solution is.
Hence, it is seen that the linear program has been maximized using the Simplex method with the maximized value being 5.


Projects usually do not want to use low-level APIs. KDB
and KeySet
is useful for plugins and to implement APIs but not to be directly used in applications.
- should be extremely easy to get started with
- should be very hard to use it wrong
- all high-level APIs should work together very nicely
- same principles
- same API style
- same error handling
- can be arbitrarily intermixed
- Thread-safety: a handle is the accepted better solution than having to care about whether it is reentrant, thread-safe, ...
- assumes that spec is available (either by compiled-in
KeySet
or exit after elektraOpen)
- many projects do not care about some limitations (no binary, no metadata) but prefer a straightforward way to get/set config
- When people hit limitations they fall back to direct use of ^KeySet^, ^Key^
- storing errors in the handle:
- Maintenance problem if error handling is added later
- only provide
KDB
, applications need to implement their own APIs:
- reduces consistency of how the API is used
- only provide generated API
- assume type as
string
if not given
- force
default
to be part of parameters
We provide 3 high-level C APIs:
- libelektra-highlevel (generic key-value getter/setter)
- libelektra-hierarchy (generic hierarchical getter/setter in a tree)
- code generator (specified key-value getter/setter with function names, KeySets, or strings from specifications)
Furthermore, we will:
- have as goal that no errors in specified keys with default can occur
- if you use
elektraGetType
before getting a value, no error can occur when getting it later
- enforce that every key has a type
- use
elektraError
as extra parameter (for prototyping and examples you can pass 0)
- Very easy to get started with, to get a key needs 3 lines of codes (without error handling):
Elektra *handle =
elektraOpen (
"/sw/elektra/kdb/#0/current", 0);
printf (
"number /mykey is " ELEKTRA_LONG_F
"\n",
elektraGetLong (handle,
"/mykey"));
- It is also easier to get started with writing new bindings.
- User can combine the different APIs.

Exploring Terraform Graphs With D3.js Part 1
TL;DR
As a newcomer to Terraform (and to AWS), I sometimes find it difficult to reason about the many available resource types, and the dependencies that can exist between them. Especially when coming to terms with larger configurations.
To address this difficulty, I want a tool to help me explore dependency graphs, and resource definitions, interactively. This is the first in a series (parts: one, two, three, four; code, documentation) of posts about building such a tool, using d3.js, starting with the simple example below1, and building upon it.
Terraform and Dependency Graphs, Introduced
Terraform is a remarkable piece of software; it’s like Make for infrastructure. Rather than transforming source into libraries and executables, Terraform transforms resource definitions (such as vm instances, dns records, s3 buckets) into running infrastructure.
Like Make, Terraform walks a dependency graph to determine the order in which it should create resources, to identify what can be done in parallel, and to re-create resources affected by changes.
Consider the following example, a straightforward Terraform graph–the same as above–laid out by the graphviz package.2
This graph is easy to understand because it has only a handful of nodes, and an obvious structure. You can easily find the single instance, its provider (aws, in this case), and the few variables they depend on. Here is a slighly more complex example.3
This is graph remains fairly legible. But larger examples tend to sprawl, making resources harder to find, and dependencies harder to trace.4
Interactive Dependency Graphs
These visualizations could be improved in various ways. Adding color, and varying the shapes used, for instance, as well as collapsing less interesting parts of the graph. But an interactive visualization offers these possibilities and more.
As a reminder of how this might work, here is the first example, again. The root node is made larger than its dependencies, and nodes of different types are assigned colors, according to an arbitrary scheme.
And here is is the second. This example is worryingly dense, compared with the Graphviz version, but being able to call up resource definititions with the mouse is a striking advantage.
One possible improvement here is to use curved edges, so that their direction is more obvious. (Tracing an edge in the clockwise direction brings you to a dependency.)
That’s an encouraging result, but what about a much larger graph, like the sprawling third example?
This version is harder to make sense of than the Graphviz version! It contains so many types of resource, for example, that it exhausts the 20-color palette, used previously.
Additionally, many of the edges overlap, or are drawn so close together, that they become hard to distinguish.
Conclusion
So far this has been a fun exercise, and I’m satisfied with it as a proof of concept. However, larger configurations remain a problem. In the next post, I plan to take up this problem, and explore possible solutions to it.

<EMAIL_ADDRESS>I'm Ben, an Electrical Engineer working for the Federal Government in Washington, DC. I do interesting things extracting, combining, visualizing, and sharing large data sets with other government agencies and the public. I earned my BS in Electrical Engineering from Virginia Tech in 2004 and my MS in Electrical and Computer Engineering from The Johns Hopkins University in 2009.
In my other life, I'm Vice President of Engineers Without Borders, Washington DC and DC State Representative to Engineers Without Borders, USA. In these capacities I work on infrastructure projects such as water, sanitation, and electricity to help meet basic human needs in developing countries.
In both these lives, I often find myself in far-flung places. While traveling, it's common to find me holding a GPS receiver collecting data for the OpenStreetMap Project.
Mbokop, Cameroon
First initiated in early 2012, the project in Mbokop, Cameroon is an EWB-DC project to bring clean drinking water to the residents of the five settlements that comprise of the village of Mbokop. An extremely remote village two-days drive from Douala, Mbokop is situated in a mountainous area of the Northwest Region of Cameroon.
During my first trip to the community in March 2013, I collected GPS data and mapped the road connecting the village to the nearest town. This data has been contributed to OpenStreetMap and can be seen here.
During our second trip to Mbokop in November 2013, we returned with large maps of the village overlaid with satellite imagery. These maps (image above) gave local residents their first real birds-eye view of their community and were essential tools in helping to identify new drinking water sources to incorporate into our water infrastructure project.
La Peña, El Salvador
In January 2014, I traveled to the village of La Peña in El Salvador. I served as a professional mentor to a university organization building composting latrines in the village. While training local residents how to build and care for the latrines, we also did door-to-door surveys taking public health data and mapping the community in the process. Although the major roads in the region were already mapped, the secondary road connecting La Peña to the nearby city of Metapán was mapped. All this data was contributed to OpenStreetMap and can be seen here.
Hato Rincon, Panama
In March 2014, a team from EWB-DC traveled to the village of Hato Rincon in Panama to perform an initial assessment for a technology center. The project will eventually involve building a structure to add onto the existing school, designing a renewable power system for the building, and outfitting the building into a computer lab. The project's long-term sustainability will be ensured by running the computer lab as an internet cafe in the evenings to help cover costs. While the team was in the community, they were able to take improved GPS data for areas previously partially mapped. Again, this data was contributed to OpenStreetMap and can be viewed here.

A website carved out of curiosity on how to get all the engineers from all the streams under one umbrella and make them work together so as to come up with new ideas and solve real world problems.
This website is going to be a community project for college students across India. It is not just for getting you projects but also for students who want to get into open source.
NSP v1.0 is hosted at nsp.com
We want development to be fun and add a competitive touch to it, and what can be
better than teaming up with the fellas of your own University?
We want to bring every talented engineers/students/developers who have immense potential but do
not have any project ideas to work on and get experienced in. Not just that, we also made this
website Open Source so that even developers/students can learn how things work at Industrial
level.
Create your own projects, make a team, divide the workload and build exciting projects right
here at NSP - where ideas come to life!
Well, this website was never intended to be launched as it was just a learning project for
Pratik and Rishi. After days of Googling, Stackoverflow , Ctrl+C and Ctrl+V, this is the best we
could come up with.
Prachal, the sole Front-end Developer of the team sat hours understanding the templates he
copied, fortunately he did.
Well later, Tushar Sadana Contributed to the Front end and the changed UI was loved by everyone!
This was our brief introduction. It's time for you to connect with the developers around the
globe and start working on your own projects. Your profile page will be your introduction to the
world, make sure to make it worth watching.
