This class allows monitoring of a collection of properties of objects of a given class, where each object's properties are observable1 and may result from objects of other observable classes. Thus, each object's properties may change indirectly as its sub-owned objects change, furthermore, these sub-changes may happen asynchronously. The inter-relationship between the main object and its dependent objects can be viewed as a graph. Cached Object Graph provides a thread-safe way of monitoring a graph of observable objects.
This scenario could be accommodated using a number of chained listeners, that tie the properties together. For example, if there are objects of a class a, b, c e.t.c, where "a" has an object b [a.setFriend(b)], b an object of c and so on, then the listener structure would typically be: a->b->c->d, where d.setFriend(e) would eventually be propogated to a. The problem in a multi-threaded system is if, for example, d.setFriend(e) and b.setFriend(g) were called at the same time. While adjusting the listeners for b, e's event may make some progress up the chain and encounter an out of date listener link, leading to inconsistent or corrupted data.
Of course, the friend classes of the objects depicted above, need not be objects of the same class as the original. This would more likely be the case in a real-world application, for example, class "a" might have a property price, which is a Price class object. The Price class object may have properties dependent on CurrentInterestRates and CurrentRisk class objects. All of these objects are observable1 and a change in any one of them would have to be propogated back to the original object a.
Cached Object Graph overcomes the problem of maintaing accurate listener links, and guarantess the integrity of the data that it returns. This is acheived using a copy (cache!) of the underlying reference graph. Only completely propogated changes are returned.
An observable object is registered as the root object for a Cached Object Graph, then rather than registering any listeners directly on the object's properties, they are registered with the Cached Object Graph instead together with a path specifier for the property that you're interested in. (For example a path might be a.friend.friend.foo or in a more real-world context a.price.currentInterestRates.) You can add as many root objects as you like to a single Cached Object Graph object. The Bhavaya GUI typically displays objects of a given class in a table. Within Bhavaya, one Cached Object Graph object is used for a table. Class properties (a registered root object's observables) are displayed in the table's columns and there is a row for each root object registered with the Cached Object Graph object.
CachedObjectGraph can operate in "synchronous" or "asynchronous" modes. This relates to whether events are propagated on the same thread as they occur on, and whether requests to a previously unmonitored area call the bean "getters" in the same thread. This is relevant when you may have getters with a high time cost (e.g. database access). In asynchronous mode, CachedObjectGraph will return the special (final static) "LOADING" object if the underlying bean getter has not returned yet. An event will be issued when the method returns and the value moves from "LOADING" to its real value. In asynchronous mode, the concept of "row ready listeners" are available. The functionality was added due to a requirement then new rows in a table (backed by COG) did not start with all cells showing "loading...". In order to solve this, if you add a "RowReadyListener" to a COG, it will set up a mechanism to notify the listener when all vivible properties of a given root object are no longer "Loading" but show the correct value. In a synchronous COG, there is not multithreading for accesses to the graph, and therefore no need for a RowReadyListener.
API summary:
| Function | Return type | Description |
|---|---|---|
| CachedObjectGraph(class beanType) CachedObjectGraph(class beanType, boolean asynchronous) |
Constructors. beanType doesn't appear to be used! The boolean determines whether asynchronous loading of an object's properties occurs. | |
| addPathListener(String propertyPath,GraphChangeListener listener) | void | propertyPath is the path to the property that you wish to observe, in relation to the root object. listener is the listener to be notified when the property specified by propertyPath changes |
| addRootObject(Object object) | void | The head of the graph of observable objects, to which all propertyPaths refer. As many root objects as required may be added. |
| dispose() | void | Stop using this CachedObjectGraph object, and remove all the listeners currently associated with it. |
| removePathListener(String propertyPath, GraphChangeListener listener) | void | Remove the listener associated with this propertyPath |
| removeRootObject(object) | void | Remove the associated root object |
propertyPaths are Strings of the form "a.b.g.foo" or "a.b.c.d.friend.foo", as taken from the figure above, and refer to the property the user is interested in, in relation to the root object a. It is assumed that if you call a.b, that a has methods getB and setB, i.e. the string would actually be translated into a.getB.
In asynchronous mode, Cached Object Graph will not block waiting for an object's properties, instead a new thread will be created for each property requested. For example, if "a.b.g.foo" actually results in a database query, with asynchronous set to true the value displayed will be "Loading..." until it is ready, and all other queries will also be initiated.
1: Observable properties are class properties that may change and have associated events and listeners.


CAMBRIDGE, Mass. — One night late in 1979, an itinerant young physicist named Alan Guth, with a new son and a year's appointment at Stanford, stayed up late with his notebook and equations, venturing far beyond the world of known physics.
He was trying to understand why there was no trace of some exotic particles that should have been created in the Big Bang. Instead he discovered what might have made the universe bang to begin with. A potential hitch in the presumed course of cosmic evolution could have infused space itself with a special energy that exerted a repulsive force, causing the universe to swell faster than the speed of light for a prodigiously violent instant.
If true, the rapid engorgement would solve paradoxes like why the heavens look uniform from pole to pole and not like a jagged, warped mess. The enormous ballooning would iron out all the wrinkles and irregularities. Those particles were not missing, but would be diluted beyond detection, like spit in the ocean.
"SPECTACULAR REALIZATION," Dr. Guth wrote across the top of the page and drew a double box around it.
On Monday, Dr. Guth's starship came in. Radio astronomers reported that they had seen the beginning of the Big Bang, and that his hypothesis, known undramatically as inflation, looked right.
Reaching back across 13.8 billion years to the first sliver of cosmic time with telescopes at the South Pole, a team of astronomers led by John M. Kovac of the Harvard-Smithsonian Center for Astrophysics detected ripples in the fabric of space-time — so-called gravitational waves — the signature of a universe being wrenched violently apart when it was roughly a trillionth of a trillionth of a trillionth of a second old. They are the long-sought smoking-gun evidence of inflation, proof, Dr. Kovac and his colleagues say, that Dr. Guth was correct.
Inflation has been the workhorse of cosmology for 35 years, though many, including Dr. Guth, wondered whether it could ever be proved.
If corroborated, Dr. Kovac's work will stand as a landmark in science comparable to the recent discovery of dark energy pushing the universe apart, or of the Big Bang itself. It would open vast realms of time and space and energy to science and speculation.
Astronomers have found evidence to support the theory of inflation, which explains how the universe expanded so uniformly and so quickly in the instant after the Big Bang 13.8 billion years ago.
Confirming inflation would mean that the universe we see, extending 14 billion light-years in space with its hundreds of billions of galaxies, is only an infinitesimal patch in a larger cosmos whose extent, architecture and fate are unknowable. Moreover, beyond our own universe there might be an endless number of other universes bubbling into frothy eternity, like a pot of pasta water boiling over.
In our own universe, it would serve as a window into the forces operating at energies forever beyond the reach of particle accelerators on Earth and yield new insights into gravity itself. Dr. Kovac's ripples would be the first direct observation of gravitational waves, which, according to Einstein’s theory of general relativity, should ruffle space-time.
Marc Kamionkowski of Johns Hopkins University, an early-universe expert who was not part of the team, said, "This is huge, as big as it gets."
He continued, "This is a signal from the very earliest universe, sending a telegram encoded in gravitational waves."
The ripples manifested themselves as faint spiral patterns in a bath of microwave radiation that permeates space and preserves a picture of the universe when it was 380,000 years old and as hot as the surface of the sun.
Dr. Kovac and his collaborators, working in an experiment known as Bicep, for Background Imaging of Cosmic Extragalactic Polarization, reported their results in a scientific briefing at the Center for Astrophysics here on Monday and in a set of papers submitted to The Astrophysical Journal.
Dr. Kovac said the chance that the results were a fluke was only one in 10 million.
Dr. Guth, now 67, pronounced himself "bowled over," saying he had not expected such a definite confirmation in his lifetime.
"With nature, you have to be lucky," he said. "Apparently we have been lucky."
The results are the closely guarded distillation of three years' worth of observations and analysis. Eschewing email for fear of a leak, Dr. Kovac personally delivered drafts of his work to a select few, meeting with Dr. Guth, who is now a professor at Massachusetts Institute of Technology (as is his son, Larry, who was sleeping that night in 1979), in his office last week.
"It was a very special moment, and one we took very seriously as scientists," said Dr. Kovac, who chose his words as carefully as he tended his radio telescopes.
Andrei Linde of Stanford, a prolific theorist who first described the most popular variant of inflation, known as chaotic inflation, in 1983, was about to go on vacation in the Caribbean last week when Chao-Lin Kuo, a Stanford colleague and a member of Dr. Kovac's team, knocked on his door with a bottle of Champagne to tell him the news.
Confused, Dr. Linde called out to his wife, asking if she had ordered anything.
"And then I told him that in the beginning we thought that this was a delivery but we did not think that we ordered anything, but I simply forgot that actually I did order it, 30 years ago," Dr. Linde wrote in an email.
Calling from Bonaire, the Dutch Caribbean island, Dr. Linde said he was still hyperventilating. "Having news like this is the best way of spoiling a vacation," he said.
By last weekend, as social media was buzzing with rumors that inflation had been seen and news spread, astrophysicists responded with a mixture of jubilation and caution.
Max Tegmark, a cosmologist at M.I.T., wrote in an email, "I think that if this stays true, it will go down as one of the greatest discoveries in the history of science."
John E. Carlstrom of the University of Chicago, Dr. Kovac's mentor and head of a competing project called the South Pole Telescope, pronounced himself deeply impressed. "I think the results are beautiful and very convincing," he said.
Paul J. Steinhardt of Princeton, author of a competitor to inflation that posits the clash of a pair of universes as the cause of genesis, said that if true, the Bicep result would eliminate his model, but he expressed reservations about inflation.
Lawrence M. Krauss of Arizona State and others also emphasized the need for confirmation, noting that the new results exceeded earlier estimates based on temperature maps of the cosmic background by the European Space Agency's Planck satellite and other assumptions about the universe.
"So we will need to wait and see before we jump up and down," Dr. Krauss said.
Corroboration might not be long in coming. The Planck spacecraft will report its own findings this year. At least a dozen other teams are trying similar measurements from balloons, mountaintops and space.
Gravity waves are the latest and deepest secret yet pried out of the cosmic microwaves, which were discovered accidentally by Arno Penzias and Robert Wilson at Bell Labs 50 years ago. They won the Nobel Prize.
Dr. Kovac has spent his career trying to read the secrets of these waves. He is one of four leaders of Bicep, which has operated a series of increasingly sensitive radio telescopes at the South Pole, where the thin, dry air creates ideal observing conditions. The others are Clement Pryke of the University of Minnesota, Jamie Bock of the California Institute of Technology and Dr. Kuo of Stanford.
"The South Pole is the closest you can get to space and still be on the ground," Dr. Kovac said. He has been there 23 times, he said, wintering over in 1994. "I've been hooked ever since," he said.
In 2002, he was part of a team that discovered that the microwave radiation was polarized, meaning the light waves had a slight preference to vibrate in one direction rather than another.
This was a step toward the ultimate goal of detecting the gravitational waves from inflation. Such waves, squeezing space in one direction and stretching it in another as they go by, would twist the direction of polarization of the microwaves, theorists said. As a result, maps of the polarization in the sky should have little arrows going in spirals.
Detecting those spirals required measuring infinitesimally small differences in the temperature of the microwaves. The group's telescope, Bicep2, is basically a giant superconducting thermometer.
"We had no expectations what we would see," Dr. Kovac said.
The strength of the signal surprised the researchers, and they spent a year burning up time on a Harvard supercomputer, making sure they had things right and worrying that competitors might beat them to the breakthrough.
The data traced the onset of inflation to a time that physicists like Dr. Guth, staying up late in his Palo Alto house 35 years ago, suspected was a special break point in the evolution of the universe.
Physicists recognize four forces at work in the world today: gravity, electromagnetism, and strong and weak nuclear forces. But they have long suspected that those are simply different manifestations of a single unified force that ruled the universe in its earliest, hottest moments.
As the universe cooled, according to this theory, there was a fall from grace, like some old folk mythology of gods or brothers falling out with each other. The laws of physics evolved, with one force after another splitting away.
That was where Dr. Guth came in.
Under some circumstances, a glass of water can stay liquid as the temperature falls below 32 degrees, until it is disturbed, at which point it will rapidly freeze, releasing latent heat.
Similarly, the universe could "supercool" and stay in a unified state too long. In that case, space itself would become imbued with a mysterious latent energy.
Inserted into Einstein's equations, the latent energy would act as a kind of antigravity, and the universe would blow itself up. Since it was space itself supplying the repulsive force, the more space was created, the harder it pushed apart.
What would become our observable universe mushroomed in size at least a trillion trillionfold — from a submicroscopic speck of primordial energy to the size of a grapefruit — in less than a cosmic eye-blink.
Almost as quickly, this pulse would subside, relaxing into ordinary particles and radiation. All of normal cosmic history was still ahead, resulting in today's observable universe, a patch of sky and stars billions of light-years across. "It's often said that there is no such thing as a free lunch," Dr. Guth likes to say, "but the universe might be the ultimate free lunch."
Make that free lunches. Most of the hundred or so models resulting from Dr. Guth's original vision suggest that inflation, once started, is eternal. Even as our own universe settled down to a comfortable homey expansion, the rest of the cosmos will continue blowing up, spinning off other bubbles endlessly, a concept known as the multiverse.
So the future of the cosmos is perhaps bright and fecund, but do not bother asking about going any deeper into the past.
We might never know what happened before inflation, at the very beginning, because inflation erases everything that came before it. All the chaos and randomness of the primordial moment are swept away, forever out of our view.
"If you trace your cosmic roots," said Abraham Loeb, a Harvard-Smithsonian astronomer who was not part of the team, "you wind up at inflation."


It was the first time I tried to have lunch at Ichiban Sushi because I love sushi lately from 2019. The result is I'm in love with Ichiban Sushi. They have some great sushi rolls, donburi, bento and also karage. So today, I'm gonna recommend you some menus at Ichiban Sushi that I think it's the top 4 on my list when I want to eat at Ichiban Sushi
This is number one in my best list! It taste really good because the dory itself and also the combination of cheese and chili powder. The taste is sooo addicting in your mouth! I recommend this menu, indeed!
This is my top 2 menu! It has crab stick, kyuri, and tobiko in it and it's like a tempura sushi. It's really juicy and tasty! You can try this if you like a simple juicy taste of sushi rolls!
If like sushi that is crunchy, this Deep Fried Roll is for you! It so chrunchy outside and soft inside.
Last but not least is Chicken Katsu Bento Set. This set you can get rice, chicken katsu, salad with mayo, cheese sauce and ice tea. This menu is like my comfort food when I want to eat rice not sushi at Ichiban Sushi. I know it sound weird when I can go to another restaurant of I want rice, but trust me, it's really good that's why I said it's my comfort food. It can't go wrong if you choose this set menu.
That's all my recommendation for today "My Best 4 Menu at Ichiban Sushi". I wish this will be informative for you guys! Please wait for my next review and recommendation!


The Detroit-Hamtramck Assembly Plant was one step away from being closed altogether as part of General Motors’ phaseout of passenger cars. As fate would have it, the latest negotiations with the UAW helped the factory keep on keeping on for the foreseeable future, and chances are Cadillac and GMC are interested in making electric trucks there.
LMC Automotive told The Detroit News“a Hummer pickup truck and SUV” would start production at Detroit-Hamtramck “in late 2021.” Citing sources in the industry, the forecaster also expects an all-new van in ‘21 along with the Escalade EV and Sierra EV in 2023.
“General Motors declined to comment on any future product plans for the plant,” but the United Auto Workers spilled the beans in regards to the electrification of Detroit-Hamtramck for next-generation trucks. No fewer than $3 billion will be invested for electric-vehicle production by 2023, translating to 2,225 jobs and 20 all-electric nameplates as well.
For the time being, Hamtramck builds the Chevrolet Impala front-driven sedan and Cadillac CT6 luxury sedan. Production has been extended until the end of February 2020 due to the six-week strike of the UAW, and after the assembly line comes to a grinding halt, it is believed that General Motors will start re-tooling and expanding the factory for the EV offensive.
What doesn’t make too much sense to anyone’s ears is the revival of the Hummer brand. The higher-ups at GM had to discontinue Hummer in 2010 following the automaker’s bankruptcy in 2009, a reorganization that also spelled the end of Saab and Saturn. Opel and Vauxhall followed suit in 2017, and as it happens, Groupe PSA helped the German and British brands bounce back to profitability after decades of losses under General Motors.
There’s no denying that the future of D-HAM is bright, and not long now, the biggest of the Big Three in Detroit will start announcing what sort of products we can expect from Detroit-Hamtramck. The Cadillac Escalade EV makes a lot of sense as a rival to the Tesla Model X, and the GMC Sierra EV would be the perfect alternative to the F-150 EV teased by the Ford Motor Company. 🏁

To provide the most accurate traffic, parking, and construction data to the community.
Lincoln Outdoors was founded at the University of Nebraska-Lincoln, by a group of students in the Journalism College. This idea came to them from countless hours in the downtown area of Lincoln, during heavily populated times. They wanted to make it easy for the Lincoln Community to have a simple way to look up when the downtown area was busy during an event, how to avoid it, where to park, and where construction is during that time.

This annotation provides all the configuration parameters that affect the pooling service.
Pooling
| Optional Element Summary | |
|---|---|
byte |
exhaustedActionType
If the Pooling.MaxPoolSize() value has been reached for a pool
(no more objects are available to be borrowed), this parameter specifies
the action to be taken when a request for an object is made to the pool. |
boolean |
LIFO
The pool can be configured to behave as a LIFO queue with respect to idle objects - always returning the most recently used object from the pool, or as a FIFO queue, where borrowObject always returns the
oldest object in the idle object pool. |
int |
maxIdle
The property is used to configure the maximum number of objects that can be in the pool at any given time. |
long |
minEvictableIdleTime
This property specifies the minimum time in milliseconds that objects can stay in a pool. |
int |
minIdle
The default minimum number of "sleeping" instances in the pool before the evictor thread (if active) spawns new objects. |
int |
numTestsPerEvictionRun
This property limits the number of objects to examine in each eviction run, if such a thread is running. |
long |
softMinEvictableIdleTime
The minimum amount of time an object may sit idle in the pool before it is eligible for eviction by the idle object evictor (if any), with the extra condition that at least "minIdle" amount of object remain in the pool. |
boolean |
testOnObtain
When true, object beans will be validated before being returned by the Pool.obtainObject()
method. |
boolean |
testWhileIdle
This property indicates to the eviction thread (if such a thread is running) that objects must be tested when they’re sitting idle in the pool. |
long |
timeBetweenEvictionRuns
This property controls the spawning of a thread and the time between its active runs. |
public abstract byte exhaustedActionType
Pooling.MaxPoolSize()
value has been reached for a pool
(no more objects are available to be borrowed), this parameter specifies
the action to be taken when a request for an object is made to the pool.
- EXHAUSTED_FAIL
(byte value of 0) - The caller is told that no
objects are available, by throwing the exception
NoSuchElementException
.
- EXHAUSTED_BLOCK
(byte value of 1) - The caller waits until an
object is returned to the pool and becomes available. The length of time
the caller waits is specified by the maxWait property. If this property
is negative, the caller waits indefinitely. If no object is available
even after the wait is over, a NoSuchElementException
exception
is thrown.
- EXHAUSTED_GROW
(byte value of 2) - The pool automatically
grows (it creates a new object and returns it to the caller).
The default setting for this parameter is EXHAUSTED_BLOCK
public abstract boolean LIFO
borrowObject
always returns the
oldest object in the idle object pool. The lifo determines whether or not
the pool returns idle objects in last-in-first-out order.
The default setting for this parameter is false.
public abstract int maxIdle
As with Pooling.MaxPoolSize()
, values should be greater than or
equal to 0. A negative value implies no limit on the number of
objects that can stay idle in the pool.
The default setting for this parameter is 8.
public abstract long minEvictableIdleTime
This value is in milliseconds and should be greater than 0. A value of 0 or less means that objects aren’t eligible for destruction based on the time they have spent in the pool alone.
The default setting for this parameter is 1800000 milliseconds or half an hour.
public abstract int minIdle
public abstract int numTestsPerEvictionRun
This value should be 0 or greater. If it’s 0, then of course, no objects will be examined. However, if you supply a negative value, you can enable fractional checking. Thus, if you supply a value of -2, it tells the evictor thread to examine 1/2 objects (roughly).
The default setting for this parameter is 3.
public abstract long softMinEvictableIdleTime
public abstract boolean testOnObtain
validated
before being returned by the Pool.obtainObject()
method. If the object fails to validate, it will be dropped from the
pool, and we will attempt to borrow another.
public abstract boolean testWhileIdle
The default setting for this parameter is false.
Validate
public abstract long timeBetweenEvictionRuns
minEvictableIdleTime()
property.
This value is in milliseconds and should be greater than 0. A value of 0 or less ensures that this thread isn’t started.
The default setting for this parameter is -1 (eviction thread isn’t started by default).

The objective of a contractor purchasing system review (CPSR) is to evaluate the efficiency and effectiveness with which the contractor spends Government funds and complies with Government policy when subcontracting. The review provides the administrative contracting officer (ACO) a basis for granting, withholding, or withdrawing approval of the contractor’s purchasing system.
(a) The ACO shall determine the need for a CPSR based on, but not limited to, the past performance of the contractor, and the volume, complexity and dollar value of subcontracts. If a contractor’s sales to the Government (excluding competitively awarded firm-fixed-price and competitively awarded fixed-price with economic price adjustment contracts and sales of commercial items pursuant to Part 12) are expected to exceed $25 million during the next 12 months, perform a review to determine if a CPSR is needed. Sales include those represented by prime contracts, subcontracts under Government prime contracts, and modifications. Generally, a CPSR is not performed for a specific contract. The head of the agency responsible for contract administration may raise or lower the $25 million review level if it is considered to be in the Government’s best interest.
(b) Once an initial determination has been made under paragraph (a) of this section, at least every three years the ACO shall determine whether a purchasing system review is necessary. If necessary, the cognizant contract administration office will conduct a purchasing system review.
A CPSR requires an evaluation of the contractor’s purchasing system. Unless segregation of subcontracts is impracticable, this evaluation shall not include subcontracts awarded by the contractor exclusively in support of Government contracts that are competitively awarded firm-fixed-price, competitively awarded fixed-price with economic price adjustment, or awarded for commercial items pursuant to Part 12. The considerations listed in 44.202-2 for consent evaluation of particular subcontracts also shall be used to evaluate the contractor’s purchasing system, including the contractor’s policies, procedures, and performance under that system. Special attention shall be given to—
(a) The results of market research accomplished;
(b) The degree of price competition obtained;
(c) Pricing policies and techniques, including methods of obtaining certified cost or pricing data, and data other than certified cost or pricing data;
(d) Methods of evaluating subcontractor responsibility, including the contractor’s use of the System for Award Management Exclusions (see 9.404) and, if the contractor has subcontracts with parties on the Exclusions list, the documentation, systems, and procedures the contractor has established to protect the Government’s interests (see 9.405-2);
(e) Treatment accorded affiliates and other concerns having close working arrangements with the contractor;
(f) Policies and procedures pertaining to small business concerns, including small disadvantaged, women-owned, veteran-owned, HUBZone, and service-disabled veteran-owned small business concerns;
(g) Planning, award, and postaward management of major subcontract programs;
(h) Compliance with Cost Accounting Standards in awarding subcontracts;
(i) Appropriateness of types of contracts used (see 16.103);
(j) Management control systems, including internal audit procedures, to administer progress payments to subcontractors; and
(k) Implementation of higher-level quality standards.
(a) The ACO shall maintain a sufficient level of surveillance to ensure that the contractor is effectively managing its purchasing program.
(b) Surveillance shall be accomplished in accordance with a plan developed by the ACO with the assistance of subcontracting, audit, pricing, technical, or other specialists as necessary. The plan should cover pertinent phases of a contractor’s purchasing system (preaward, postaward, performance, and contract completion) and pertinent operations that affect the contractor’s purchasing and subcontracting. The plan should also provide for reviewing the effectiveness of the contractor’s corrective actions taken as a result of previous Government recommendations. Duplicative reviews of the same areas by CPSR and other surveillance monitors should be avoided.
The cognizant ACO is responsible for granting, withholding, or withdrawing approval of a contractor’s purchasing system. The ACO shall—
(a) Approve a purchasing system only after determining that the contractor’s purchasing policies and practices are efficient and provide adequate protection of the Government’s interests; and
(b) Promptly notify the contractor in writing of the granting, withholding, or withdrawal of approval.
(a) The notification granting system approval shall include—
(1) Identification of the plant or plants covered by the approval;
(2) The effective date of approval; and
(3) A statement that system approval—
(i) Applies to all Federal Government contracts at that plant to the extent that cross-servicing arrangements exist;
(ii) Waives the contractual requirement for advance notification in fixed-price contracts, but not for cost-reimbursement contracts;
(iii) Waives the contractual requirement for consent to subcontracts in fixed-price contracts and for specified subcontracts in cost-reimbursement contracts but not for those subcontracts, if any, selected for special surveillance and identified in the contract Schedule; and
(iv) May be withdrawn at any time at the ACO’s discretion.
(b) In exceptional circumstances, consent to certain subcontracts or classes of subcontracts may be required even though the contractor’s purchasing system has been approved. The system approval notification shall identify the class or classes of subcontracts requiring consent. Reasons for selecting the subcontracts include the fact that a CPSR or continuing surveillance has revealed sufficient weaknesses in a particular area of subcontracting to warrant special attention by the ACO.
(c) When recommendations are made for improvement of an approved system, the contractor shall be requested to reply within 15 days with a position regarding the recommendations.
(a) The ACO shall withhold or withdraw approval of a contractor’s purchasing system when there are major weaknesses or when the contractor is unable to provide sufficient information upon which to make an affirmative determination. The ACO may withdraw approval at any time on the basis of a determination that there has been a deterioration of the contractor’s purchasing system or to protect the Government’s interest. Approval shall be withheld or withdrawn when there is a recurring noncompliance with requirements, including but not limited to—
(1) Certified cost or pricing data (see 15.403);
(2) Implementation of cost accounting standards (see 48 CFR Chapter 99 (FAR Appendix, loose-leaf edition));
(3) Advance notification as required by the clauses prescribed in 44.204; or
(4) Small business subcontracting (see Subpart 19.7).
(b) When approval of the contractor’s purchasing system is withheld or withdrawn, the ACO shall within 10 days after completing the in-plant review (1) inform the contractor in writing, (2) specify the deficiencies that must be corrected to qualify the system for approval, and (3) request the contractor to furnish within 15 days a plan for accomplishing the necessary actions. If the plan is accepted, the ACO shall make a follow-up review as soon as the contractor notifies the ACO that the deficiencies have been corrected.
Upon request, the ACO may inform a contractor that the purchasing system of a proposed subcontractor has been approved or disapproved, but shall caution that the Government will not keep the contractor advised of any changes in the approval status. If the proposed subcontractor’s purchasing system has not been reviewed, the contractor shall be so advised.
The ACO shall distribute copies of CPSR reports; notifications granting, withholding, or withdrawing system approval; and Government recommendations for improvement of an approved system, including the contractor’s response, to at least—
(a) The cognizant contract audit office;
(b) Activities prescribed by the cognizant agency; and
(c) The contractor (except that furnishing copies of the contractor’s response is optional).

Susan Granger's review of "THE BASKET" (North by Northwest Entertainment)
The impact of regional film-making is growing and this independent "family film" is one of the best to emerge in recent years. Working with three friends, film-maker Rich Cowan has created a character-driven, intriguing tale of opera and basketball, nostalgia and history, love and war set amid the rolling wheat fields of Washington State. His company, North by Northwest, raised the $3 million budget for the period drama, set in the rural town of Waterville in the midst of World War I. The story begins as a pastor/physician welcomes two German war orphans, 12 year-old Helmut (Robert Karl Burke) and his 17 year-old sister, Brigitta (Amber Willenborg), into his home. At the same time, a new school teacher named Martin Conlon (Peter Coyote) arrives from Boston, bringing with him phonograph records of an evocative German opera called "The Basket" about a stranger who saves a town that is threatened by barbarians at the gates. The plot of the opera obviously parallels the suspicion, prejudice and intolerance of Waterville's citizens, much to the dismay of a sympathetic farmer's wife (Karen Allen) who bears her own wartime tragedy. "Why are you teaching the children a German opera when we are at war with them?" she asks. Conlon also introduces a then-new sport called "basketball" with its emphasis on teamwork, saying: "To defend a mighty wall, each one must fight for something small." Ultimately, Waterville challenges Spokane's experienced team for money - which will allow the farmers to buy the new thresher that they desperately need for harvest season. Despite its slow-pacing, on the Granger Movie Gauge of 1 to 10, "The Basket" is a warm, heartfelt, uplifting 7. It's a gem, one of those rare, thoughtful, beautiful movies with a feeling of "A River Runs Through It."

Gal Gadot became a household name when she starred in the first female superhero movie of the 2010’s. As Wonder Woman, Gal Gadot worked for a very long time in order to be in shape to play the Amazonian goddess. This workout comprised of three very important aspects: workout, diet, and lifestyle. To start off, to get the body of Wonder Woman Gal Gadot had to spend an hour a day in the gym, get a healthy amount of sleep, and regulated her nutrition, what she did in those 23 hours she was not working out was just as important as the workout itself.  The workout was meant to add tone, so it included mostly cardio with a mixture of weight training. (For more information click here.)
One of Gadot’s main workouts is as follows. First, she started off with a 5 minute rowing warm up. Then, do 5 minutes of burpees, and doing about 50. Then do 1 minute of mountain climbers. Proceeding to do 1 minute of bird dogs. Then doing another minutes of burpees. Then do another minute of mountain climbers. Then do seven sets of three pull ups. Afterward doing 5 sets of 15 pushups. She, like many other celebrities finishes her workout with 15 minutes of cardio, usually running on a treadmill.
In conclusion, this workout comprised of three very important aspects: workout, diet, and lifestyle. To start off, to get the body of Wonder Woman Gal Gadot had to spend an hour a day in the gym, get a healthy amount of sleep, and regulated her nutrition, what she did in those 23 hours she was not working out was just as important as the workout itself.  The workout was meant to add tone, so it included mostly cardio with a mixture of weight training.


The Process it Takes

- Draft Process
At this stage I will write a Pseudocode, a skeleton and
of what the application will contain and diagram of what it will look after completion.
- Designing the Prototype
A rough archetype will be implemented,
images will be picked , colors to include background colors, Font size, styles and a defined layout
- Testing
The finished project will then be ran through a vigous testing systems
and browsers for compatibility.
- Completion
The best and final step will to hand over the completed project.
After this your will have free consultations and updates for 30 days.
If you choose to have me manage your site then I will keep the adminstatrative information otherwise you get these too. Remember to keep them safe;you will need then it to make future changes or updates.


Introduction
Why?
There are a number of excellent message bus implementations available, all with different features. What makes this different?
The distinguishing feature of this message bus is it's support for select feed publishers. Typically a message bus implements a broadcast feed (e.g. RabbitMQ, Redis, etc). The source publishes messages on topics while clients subscribe to topics of interest to them.
In a select feed the publisher gets notified when a client subscribes or unsubscribes from a topic. This allows the publisher to only publish data that is being listened to, and also to send an initial image to the new subscriber, after which it publishes deltas to all subscribers.
Pros
The notification capability provides a number of useful features:
- It reduces network bandwidth by only sending messages that clients have requested.
- It allows for dynamic messaging. For example a client may request AAPL.2020-01-01/2020-02-01 to get prices for the given range.
Cons
As all messages pass through a single broker, this beccomes a processiong bottleneck.
Other Feastures
There are a number of other features provided:
- SSL transport
- Authentication: LDAP, JWT, and password file.
- Authorization. The server can be configured to only send data for which the client is authorized.


Mixed Emotions For Mick McCarthy As Denmark Draw Not Enough In Dublin
by Oisin McQueirnsIreland manager Mick McCarthy understandably had mixed emotions as he saw his side draw 1-1 against Denmark and miss out on automatic qualification for Euro 2020 at the Aviva on Monday night.
The Boys in Green put in arguably their best performance of the campaign so far as they drew with their familiar foes but a point in their final group game wasn’t enough to see them into the two automatic qualification spots for next summer’s tournament.
The likes of David McGoldrick, Matt Doherty and Glenn Whelan were all standouts in front of a raucous home crowd in Dublin, but the draw means that Ireland now face two one legged-playoff games in March.
“I have mixed emotions,” explained McCarthy following the draw.
“I’m disappointed that we didn’t qualify (automatically) but I’m immensely proud of my players.”
“We played well and we competed well. I said before the game if they leave everything on the pitch and give everything for me, the lads, then I’ll take that and I’ve got to take the result but that is the only thing I’m disappointed with.”
Ireland had the better of the opening 70 minutes in Dublin and when Denmark did find the goal through Martin Braithwaite it largely came against the run of play.
McCarthy outlined that it’s “always a kick in the nuts when you concede” and the manner in which Ireland did, through the former Middlesbrough striker sneaking in between Shane Duffy and Doherty at the back post, certainly disappointing.
The performance though will give McCarthy’s men a much needed boost ahead of March’s playoffs with Ireland knowing that if they can emulate Monday night’s display then they won’t be far off qualification.
McCarthy believes that his side will be mentally tough enough to bounce back from the disappointment of the Danish draw.
“We will come back in in March we’ll be playing a different team, we’ll come back and try and get a performance out of them. Sometimes I think you believe we are very shallow and we’re not mentally tough.
“We have bad performances and bad results all the time, you’ve got to come back and play well. You have to get back in and get back it’s as simple as that and the lads have done it, I’m delighted with them.”

Also known as "How do i throw my ethereum into a pit of fuckery
Hey there! I see you're interested in testing how strong your hands are
Or maybe you're just after those masternodes and the prospects of dooming your friends to an eternity of bagholding inviting them into a profitable arrangement.
First thing's first, let's get you on the same page as everyone else; If you don't have it already you're gonna need Metamask.
Metamask is a kind of browser extension that allows you to set up an ethereum wallet that you can use to interact with Smart-Contracts or dAPPs like this
Click the Cute Fox Download Button
You should now have a little fox icon right next to your URL bar on your browser of choice; click that and follow the instructions to set up a wallet. Make sure you absolutely write down your seed phrase, and maybe even email yourself a copy!
Metamask updates frequently, and as long as you have that sentence of random words you can always get back to your wallet.
Now that you have a wallet set up in metamask, the Smart Contract Exchange should appear correctly!  That address works just like any of the other addresses you've used on exchanges for withdrawals or deposits. Just use this address as a location to withdraw to from anywhere else that you're holding ETH or trading your life savings for ETH on.
This is also a full fledged ethereum address, which can hold not only the ETH you're going to use, but also any ERC20 tokens you get back!
Armed with this knowledge, you are now well equipped to compete with others on the Smart Contract Exchange, Go ahead, have fun; and remember to never invest anything you can't afford to lose.


XLS: Accelerated HW Synthesis
What is XLS?
XLS implements a High Level Synthesis (HLS) toolchain which produces synthesizable designs (Verilog and SystemVerilog) from flexible, high-level descriptions of functionality. It is fully Open Source: Apache 2 licensed and developed via GitHub.
XLS (Accelerated HW Synthesis) aims to be the Software Development Kit (SDK) for the End of Moore's Law (EoML) era. In this "age of specialization", software and hardware engineers must do more co-design across their domain boundaries -- collaborate on shared artifacts, understand each other's cost models, and share tooling/methodology. XLS attempts to leverage automation, software engineers, and machine cycles to accelerate this overall process.
In effect, XLS enables the rapid development of hardware IP that also runs as efficient host software via "software style" methodology. A single XLS source program runs at native speeds for use in host software or a simulator, but that source can also be used to generate hardware block output -- the XLS tools' correctness ensures (and provides tools to help formally verify) that they are functionally identical.
XLS is used inside of Google for generating feed-forward pipelines from "building block" routines / libraries that can be easily retargeted, reused, and composed in a latency-insensitive manner.
XLS also supports concurrent processes, in Communicating Sequential Processes (CSP) style, that allow pipelines to communicate with each other and induct over time. This feature is still under active development but today supports base use cases.
XLS is still experimental, undergoing rapid development, and not an officially supported Google product. Expect bugs and sharp edges. Please help by trying it out, running through some tutorials, reporting bugs, and letting us know what you think!

Building From Source
Currently, XLS must be built from source using the Bazel build system.
Note: Binary distributions of the XLS library are not currently available, but we hope to enable them via continuous integration, see this issue.
The following instructions are for the Ubuntu 20.04 (Focal Fossa) and Ubuntu 22.04 (Jammy Jellyfish) Linux distributions.
We start by assuming Bazel has been installed. On an average 8-core VM, a full initial build (including the C++ frontend) may take up to 6 hours. A build without the C++ frontend may take about 2 hours. Please see the two corresponding command lines below:
~$ git clone https://github.com/google/xls.git
~$ cd xls
~/xls$ # Follow the bazel install instructions:
~/xls$ # https://bazel.build/install/ubuntu
~/xls$ # Afterwards we observe:
~/xls$ bazel --version
bazel 5.2.0
~/xls$ # Note we're going to tell Ubuntu that `/usr/bin/env python` is actually python3
~/xls$ # here, since that is not the case by default on Ubuntu 20.04.
~/xls$ # This is important. Without this step, you may experience cryptic error messages:
~/xls$ sudo apt install python3-distutils python3-dev libtinfo5 python-is-python3
~/xls$ # Now build/test in optimized build mode.
~/xls$ # If you don't plan on using the C++ frontend, which is not needed to get started,
~/xls$ # use this command line:
~/xls$ bazel test -c opt -- //xls/... -//xls/contrib/xlscc/...
~/xls$ # To build everything, including the C++ frontend:
~/xls$ bazel test -c opt -- //xls/...
The build needs Python3 to be available. If your python3 binary is at an
unusual location, you can tell bazel
by providing a command line flag
--repo_env PYTHON_BIN_PATH=/path/to/python3
for bazel
to find python3
.
Reference build/test environment setups are also provided via Dockerfile
s:
~$ git clone https://github.com/google/xls.git
~$ cd xls
~/xls$ # Several Dockerfiles are available to choose from:
~/xls$ docker build . -f Dockerfile-ubuntu-20.04 # Performs optimized build and test.
~/xls$ docker build . -f Dockerfile-ubuntu-20.10
~/xls$ docker build . -f Dockerfile-ubuntu-22.04
Stack Diagram and Project Layout
Navigating a new code base can be daunting; the following description provides a high-level view of the important directories and their intended organization / purpose, and correspond to the components in this XLS stack diagram:
dependency_support
: Configuration files that load, build, and expose Bazel targets for external dependencies of XLS.docs
: Generated documentation served via GitHub pages: https://google.github.io/xls/docs_src
: Markdown file sources, rendered todocs
via mkdocs.-
xls
: Project-named subdirectory within the repository, in common Bazel-project style.build
: Build macros that create XLS artifacts; e.g. convert DSL to IR, create test targets for DSL code, etc.codegen
: Verilog AST (VAST) support to generate Verilog/SystemVerilog operations and FSMs. VAST is built up by components we call generators (e.g. PipelineGenerator, SequentialGenerator for FSMs) in the translation from XLS IR.common
: "base" functionality that layers on top of standard library usage. Generally we use Abseil versions of base constructs wherever possible.contrib/xlscc
: Experimental C++ syntax support that targets XLS IR (alternative path to DSLX) developed by a sister team at Google, sharing the same open source / testing flow as the rest of the XLS project. May be of particular interest for teams with existing C++ HLS code bases.data_structures
: Generic data structures used in XLS that augment standard libraries; e.g. BDDs, union find, min cut, etc.delay_model
: Functionality to characterize, describe, and interpolate data delay for XLS IR operations on a target backend process. Already-characterized descriptions are placed inxls/delay_model/models
and can be referred to via command line flags.dslx
: A DSL (called "DSLX") that mimics Rust, while being an immutable expression-language dataflow DSL with hardware-oriented features; e.g. arbitrary bitwidths, entirely fixed size objects, fully analyzeable call graph. XLS team has found dataflow DSLs are a good fit to describe hardware as compared to languages designed assume von Neumann style computation.fuzzer
: A whole-stack multiprocess fuzzer that generates programs at the DSL level and cross-compares different execution engines (DSL interpreter, IR interpreter, IR JIT, code-generated-Verilog simulator). Designed so that it can easily be run on different nodes in a cluster simultaneously and accumulate shared findings.examples
: Example computations that are tested and executable through the XLS stack.experimental
: Artifacts captured from experimental explorations.interpreter
: Interpreter for XLS IR - useful for debugging and exploration. For cases needing throughput, consider using the JIT (below).ir
: XLS IR definition, text parser/formatter, and facilities for abstract evaluation.jit
: LLVM-based JIT for XLS IR. Enables native-speed execution of DSLX and XLS IR programs.modules
: Hardware building block DSLX "libraries" (outside the DSLX standard library) that may be easily reused or instantiated in a broader design.netlist
: Libraries that parse/analyze/interpret netlist-level descriptions, as are generally given in simple structural Verilog with an associated cell library.passes
: Passes that run on the XLS IR as part of optimization, before scheduling / code generation.scheduling
: Scheduling algorithms, determine when operations execute (e.g. which pipeline stage) in a clocked design.simulation
: Code that wraps Verilog simulators and generates Verilog testbenches for XLS computations. iverilog is currently used to simulate as it supports non-synthesizable testbench constructs.solvers
: Converters from XLS IR into SMT solver input, such that formal proofs can be run on XLS computations; e.g. Logical Equalence Checks between XLS IR and a netlist description. Z3 is used as the solver engine.synthesis
: Interface that wraps backend synthesis flows, such that tools can be retargeted e.g. between ASIC and FPGA flows.tests
: Integration tests that span various top-level components of the XLS project.tools
: Many tools that work with the XLS system and its libraries in a decomposed way via command line interfaces.uncore_rtl
: Helper RTL that interfaces XLS-generated blocks with device top-level for e.g. FPGA experiments.visualization
: Visualization tools to inspect the XLS compiler/system interactively. See IR visualization.

In one of my previous entries I mentioned Fedora and how it encourages the use of free software. My first impression was so overwhelmingly positive that it got me hooked already. I finally feel committed to a specific distribution and I am more than eager to contribute by solving people’s problems (this I particularly enjoy) and reporting bugs. I wanted to share my opinion on a number of features of Fedora which I found most compelling:
While for many Linux enthusiasts this may mean a strong enterprise/industry focus and less care for open-source and free software, this is not true. Fedora is funded by Red Hat and serves as a testing ground for features to be later incorporated in Red Hat Enterprise Linux (RHEL), however it has a soul of its own. One that’s driven largely by a community of dedicated users and developers, who primarily care about popularizing Linux and free software. From a different perspective, one has to understand and appreciate the huge contribution of Red Hat to Linux development when it (Linux) was still in its infancy (1990s).
Recently, I focused on Linux distributions which are easy to install and offer a good selection of tools to use right from the
get-go. I’m slightly tired of setting up new PCs from scratch (sorry, Arch :() and fixing configuration issues that shouldn’t
even exist anymore (oh, Debian and openSUSE...), hence my choice of Xubuntu, Fedora and the likes. Among the ones I tested,
Fedora seemed to sport the most sane combination of features. Reasonable software selection (especially the LXDE spin!),
a visually pleasing, yet not over-beautified desktop experience (calm themes rich in blue), etc. Installing additional software
also seemed straightforward and fast. yum
and dnf
offer a much more descriptive output than
Debian/Ubuntu’s apt
(seriously, what was wrong with aptitude again...?) and speed-wise are on par with Arch’s
pacman
. Furthermore, aside from Arch Linux, Fedora was the only distribution where Skype worked instantly after
installation (openSUSE, how about sorting those dependencies out yourself, hmm?).
All Linux distributions have their communities, but usually they are somehow restricted to forums and/or IRC channels. Arch Linux has its Arch User Repositories (AUR) as an additional means of software-related interactions between users and package maintainers. However, Arch adheres strongly to the KISS principle and the community is rather small. Fedora has basically everything. There are forums, IRC channels, a magazine announcing new development decisions or features, gatherings (Flocks), reports, etc. One can really feel that the community is a crucial part of the distribution. Not to mention how easy it is to contribute by testing packages or writing documentation.
Fedora is the first to get the freshest and most exciting Linux features. Most packages are close to their respective upstream versions and there is a great deal of collaboration between Fedora and upstream projects (including kernel.org) going on. The software is cutting-edge, but it doesn’t make the user bleed. Interesting new features are covered by the Fedora Magazine in an encouraging manner. It’s hard not to get excited!
Currently, I am in a state of deep euphoria and I would like Fedora to be on all of my computers (and the computers of my colleagues, for that matter!). It’s also nice to see people wearing classy blue hats around you. Emphasizes the ‘unity’ in ‘community’. It seems that my distro-hopping habit has finally stopped and I can fully concentrate on my new goal - programming in Python. More on that in my future entries.

A core set of procedures for creating and manipulating heterogeneous multidimensional arrays is proposed. The design is consistent with the rest of Scheme and independent of other container data types. It provides easy sharing of parts of an array as other arrays without copying, encouraging a declarative style of programming.
The specification is based on an original contribution by Alan Bawden in 1993.


Generalized Linear Mixed Effects Models¶
Generalized Linear Mixed Effects (GLIMMIX) models are generalized linear models with random effects in the linear predictors. Statsmodels currently supports estimation of binomial and Poisson GLIMMIX models using two Bayesian methods: the Laplace approximation to the posterior, and a variational Bayes approximation to the posterior. Both methods provide point estimates (posterior means) and assessments of uncertainty (posterior standard deviation).
The current implementation only supports independent random effects.
Technical Documentation¶
Unlike Statsmodels mixed linear models, the GLIMMIX implementation is not group-based. Groups are created by interacting all random effects with a categorical variable. Note that this creates large, sparse random effects design matrices exog_vc. Internally, exog_vc is converted to a scipy sparse matrix. When passing the arguments directly to the class initializer, a sparse matrix may be passed. When using formulas, a dense matrix is created then converted to sparse. For very large problems, it may not be feasible to use formulas due to the size of this dense intermediate matrix.

Sander Berge drops Liverpool transfer hint after manager confirmed interest
Sander Berge is rumoured to be on Liverpool's transfer wish list after impressing against them for Genk in the Champions League. Napoli are also said to be interested
by Alex SmithSander Berge has dropped a fresh Liverpool transfer hint by admitting that he wants to play at Anfield "as much as possible".
Genk midfielder Berge has been linked with a move to the Reds following his eye-catching performances against Jurgen Klopp's men in the Champions League recently.
The Norway international has scored two goals in 15 Jupiler Pro League in Belgium this season, along with being an ever-present in the Champions League.
And the 21-year-old has been full of praise for Liverpool and said he wants to make more regular trips to Merseyside.
"Playing at Anfield is a dream for everyone in the world, and not least for Norwegians," Berge said to TV2.
"Liverpool are the best team [at the moment] and have the most fans.
"So I could certainly like to play at Anfield as often as possible."
Berge has also attracted interest from Napoli, with reports he could leave Genk for a fee of around £18million.
And sporting director Dimitri De Conde has appeared to fuel speculation Berge could leave the club as he confirmed Liverpool "follow him carefully" as they consider hijacking Napoli's move.
De Conde told Radio Punto Nuovo: “If Napoli has already blocked Berge? I read it and it’s not like that. Napoli are interested in Sander and it’s is a possibility.
“We also know Liverpool follow him carefully. Klopp spoke to the boy after the Anfield game, congratulating him on the performance.
“In Italy there are clubs that follow Berge and Napoli could be one of these, but to date we have no concrete offers on the table. It could even change in the coming weeks.
“Berge to Napoli in January? We don’t know. We are currently fighting for our seasonal goals and we are in a complicated situation.
“Our intention is to hold on to Sander until the end of the season, but we can’t make any predictions. If the big clubs come knocking at our door, we will have to start negotiations, just as the agent has to do.
“These are situations we can’t predict, we’re focused on our season, hoping to keep Sander until May. Then if a top club like Napoli is serious, we will sit at the same table to negotiate, it is logical.
“The current valuation of Berge? We do not talk about figures; we do not set a price at the moment. We will see when we find ourselves in a negotiation.”

in the input field and arranging them either in a grid or randomly.
After this you can drag them around by clicking and dragging. Once you're satisfied with the layout,
press the start simulation button.
Simulation:
Click a glowstep to mimic someone stepping on it. You can hold shift and drag it around. The nearest neighbours will be
recalculated on dropping the glowstep.


Optional packages are packages of Java classes and associated native code that application developers can use to extend the functionality of the core platform. The extension mechanism allows the Java virtual machine (VM) to use the optional-package classes in much the same way as the VM uses bootstrap classes. (Bootstrap classes are those implementing the core platform, contained in jre/lib/rt.jar and several other important jar files. These include classes of the public API such as java.lang, java.io, etc., and classes supporting the platform's internationalization/localization features.). Like bootstrap classes, classes in optional packages do not have to be placed on the class path. The extension mechanism also provides a way for needed optional packages to be retrieved from specified URLs when they are not already installed in the Java 2 Runtime Environment or JDK.
Optional packages are embodied in JAR files, and every JAR file is a potential optional package. A JAR file can be made to play the role of an optional package in two ways:
When the VM is searching for a class of a particular name, it will first look among the bootstrap classes. If it fails to find the desired class there, it will next look for the class among any installed optional packages. If it doesn't find the class among either the bootstrap classes or the installed optional packages, the VM will search among any download optional packages referenced by the application or applet. The VM only searches the class path if it fails to find a class among the bootstrap classes or optional package classes.
Deprecated: Support for installed optional packages has been deprecated and may be removed in a future release.
Installed optional packages are JAR files in the following directories:
lib/ext
(in the JRE)jre/lib/ext
(in the JDK)Classes within JAR files in this directory can be used by applets and applications much as if they were part of the set of bootstrap classes, without having to explicitly include them in the class path.
An installed optional package's native code binaries, if any, are placed in
jre\bin
(Microsoft Windows)jre/lib/<arch>
(Solaris operating
environment)where <arch>
is the Solaris processor
architecture, either sparc
or i386
.
Native libraries may also be placed in
jre/lib/ext/<arch> for both Microsoft Windows and
the Solaris operating environment, where <arch> will
be i386 on Microsoft Windows systems. The
jre/lib/ext/<arch> directory is searched
after jre\bin or
jre/lib/<arch>.
When the Java VM encounters a class name, it looks first for the class in the runtime environment. If it fails to find the desired class among the classes that are part of the standard runtime environment, the VM will search for the class in any JAR files in the optional packages directory.
Note that there is nothing special about any particular JAR file
itself or the classes it contains that makes it an installed
optional package. It is an installed optional package by virtue of
its location in jre/lib/ext
.
The manifest of an installed optional package's JAR file should contain version and vendor information for use by applets that need to use the optional packages classes. The attributes that specify the version and vendor information are described in Optional Package Versioning. Here is an example of what such a manifest might look like:
Manifest-version: 1.0 Extension-Name: javax.extension Specification-Version: 1.0 Specification Vendor: Oracle Corporation. Implementation-Vendor: Oracle Corporation. Implementation-Vendor-Id: com.sun Sealed: true
This version and vendor information can be used by the Java Plug-in when running an applet to see if optional packages needed by the applet are installed, are up to date, and are from the vendor requested by the applet. If not, the Java Plug-in can prompt the applet user to download the proper optional package. See Optional Package Versioning for more information.
If a class is not found after searching both the system classes and the classes in the installed optional packages, the extension mechanism will search for the class in a download optional package....
A download optional package is a JAR files that is specified in the Class-Path header field in the manifest of another JAR files. Classes in download optional packages may be used by classes in the referencing JAR file. In a typical situation, an applet will be bundled in a JAR file whose manifest references a JAR file (or several JAR files) that will serve as an optional package for the purposes of that applet. Optional packages may reference each other in the same way.
A Class-Path header might look like this, for example:
Class-Path: servlet.jar infobus.jar acme/beans.jar
This specifies that the classes in the files
servlet.jar
, infobus.jar
, and
acme/beans.jar
will serve as optional pakcages for
purposes of the classes in the JAR file whose manifest contains
this header. The URLs in the Class-Path field are given relative to
the URL of the JAR file of the applet or application.
Unlike the case of installed optional packages, the location of the JAR files that serve as download optional packages is irrelevent. A download optional package is an optional package because it is specified as the value of the Class-Path header in another JAR file's manifest, not because it has any particular location.
Another difference between installed and download optional packages is that only applets and applications bundled in a JAR file can make use of download optional packages. Applets and applications not bundled in a JAR file don't have a manifest from which to reference download optional packages.
When searching for a class, the VM first searches among the classes in the system classes and in any installed optional packages. If the class is not found in either the system classes or in the installed optional packages, the VM will search for the class in any download optional packages referenced by the manifest of the application or applet. A download optional package will not be downloaded if a desired class is found among the installed optional packages, even if the download optional package is referenced by the manifest file of the applet or application.
The extension mechanism will not install a download optional package in the JRE or JDK directory structure. Download optional packages do not become installed extentions after they have once been downloaded.
Unlike installed optional packages, download optional packages cannot have any native code.


| PostgreSQL 9.5.19 Documentation | |||
|---|---|---|---|
| Prev | Up | Chapter 8. Data Types | Next |
PostgreSQL provides the standard SQL type boolean; see Table 8-19. The boolean type can have several states: "true", "false", and a third state, "unknown", which is represented by the SQL null value.
Boolean constants can be represented in SQL queries by the SQL key words TRUE, FALSE, and NULL.
The datatype input function for type boolean accepts these string representations for the "true" state:
| true |
| yes |
| on |
| 1 |
| false |
| no |
| off |
| 0 |
The datatype output function for type boolean always emits either t or f, as shown in Example 8-2.
Example 8-2. Using the boolean Type
CREATE TABLE test1 (a boolean, b text); INSERT INTO test1 VALUES (TRUE, 'sic est'); INSERT INTO test1 VALUES (FALSE, 'non est'); SELECT * FROM test1; a | b ---+--------- t | sic est f | non est SELECT * FROM test1 WHERE a; a | b ---+--------- t | sic est
The key words TRUE and FALSE are the preferred (SQL-compliant) method for writing Boolean constants in SQL queries. But you can also use the string representations by following the generic string-literal constant syntax described in Section <IP_ADDRESS>, for example 'yes'::boolean.
Note that the parser automatically understands that TRUE and FALSE are of type boolean, but this is not so for NULL because that can have any type. So in some contexts you might have to cast NULL to boolean explicitly, for example NULL::boolean. Conversely, the cast can be omitted from a string-literal Boolean value in contexts where the parser can deduce that the literal must be of type boolean.


Alice’s Adventures in Wonderland
Lewis Carroll
“Come, there’s no use in crying like that!” said Alice to herself, rather sharply; “I advise you to leave off this minute!” She generally gave herself very good advice (though she very seldom followed it), and sometimes she scolded herself so severely as to bring tears into her eyes; and once she remembered trying to bos her own ears for having cheated herself in a game of croquet she was playing against herself, for the curious child was very fond of pretending to be two people. “But it’s no use now,” thought poor Alice, “to pretend to be two people! Why, there’s hardly enough of me left to make one respectable person!”
Soon her eyes fell on a little glass box that was lying under the table: she opened it, and found in it a very small cake, on which the words “Eat me” were beautifully marked in currants.
“Well, I’ll eat it,” said Alice, “and if it makes me grow larger, I can reach the key; and if it makes me grow smaller, I can creep under the door; so either way I’ll get into the garden, and I don’t care which happens!”
She ate a little bit, and said anxiously to herself, “Which way? Which way?” holding her hand on the top of her head to feel which way it was growing, and she was quite surprised to find that she remained the same size: to be sure, this generally happens when one eats cake, but Alice had got so much into the way of expecting nothing but out-of-the-way things to happen, that it seemed quite dull and stupid for life to go on in the common way.
