New York City 'F--- the Police' protest turns violent, dozens of arrests reported
by Brie StimsonDemonstrators shouting "F--- the police!" turned violent in the Harlem neighborhood of New York City on Friday evening, vandalizing city buses and police cruisers, according to reports.
Nearly 60 people were arrested in what organizers said was a protest of excessive policing of the city's subway system.
The outburst came in the wake of New York Gov. Andrew Cuomo calling for 500 additional police officers to join the state-run Metropolitan Transit Authority's force and several viral videos showing subway arrests that some thought showed excessive force, including pointing a gun at a teenager who jumped a turnstile, New York's WNBC-TV reported.

“F--- cops and every racist, fascist person out here," a protester who identified herself as Alicia, 22, of the Bronx, told the New York Post. "These are our neighborhoods."

At one point, New York City Transit tweeted that subway lines were bypassing the 125th Street station in Harlem and videos posted online showed that police had temporarily closed the station.
Videos posted online showed crowds flowing into the streets and city police officers making arrests. One video showed a subway turnstile had been vandalized.
The New York Police Department tweeted shortly before 7 p.m. that evening commuters should expect delays in vehicular traffic and on public tranist in the area.
A previous protest in the city's Brooklyn borough on Nov. 1 drew a supportive Twitter message from U.S. Rep. Alexandria Ocasio-Cortez, D-N.Y.
“Ending mass incarceration means challenging a system that jails the poor to free the rich,” the left-wing freshman congresswoman tweeted, retweeting a video of protesters jumping subway turnstiles in Brooklyn.
As of early Saturday, the congresswoman hadn't tweeted about the Harlem protest.

The city reported last year that turnstile jumpers and bus-fare cheaters cost the MTA $215 million, according to Bloomberg.

Bolivian police battle with Morales supporters, death toll jumps to 8; over 100 injured
Morales resigned under pressure from Bolivia´s police and military last Sunday after evidence of vote-rigging tainted his October 20 election victory.
Clashes between security forces and Bolivian coca farmers loyal to ousted former President Evo Morales left as many as eight dead and more than 100 injured late on Friday, the regional ombudsman told Reuters, prompting Morales to decry a "massacre."
Morales resigned under pressure from Bolivia's police and military last Sunday after evidence of vote-rigging tainted his October 20 election victory. He then fled to Mexico.
The leftist and charismatic former coca farmer has called his ouster a "coup," and decried growing allegations of heavy-handed repression by Bolivian security forces.
"The coup leaders massacre indigenous people and humble people for asking for democracy," Morales said on Twitter late Friday, following reports of mounting deaths.
The violence in Bolivia adds to a wave of unrest in the region, including in neighbour Chile, where protests over social inequalities spiralled out of control and left at least 20 dead.
Cochabamba regional ombudsman Nelson Cox said hospital records in the coca farming region showed the "vast majority" of Friday´s deaths and injuries had been caused by bullet wounds. He called the reaction of security forces in the region an "act of repression."
"We are working with the national ombudsman´s office to conduct autopsies to determine the cause of death and seek justice for these victims," Cox told Reuters in an interview Saturday morning.
Supporters continue to agitate for Morales, blocking major highways, cutting oil pipelines and launching mass protests in the streets of La Paz, El Alto and in coca farming regions long loyal to him.
Though the capital La Paz was calm Saturday morning, highway blockades prompted panic on the streets, with many rushing to hoard groceries as supplies ran low and prices rose.
Bolivia´s national ombudsman said Friday that total deaths had hit 19 since the Oct. 20 election, a number which has accelerated over the last week.
The rising body count prompted Morales to strike a more conciliatory tone with the government of interim President Jeanine Anez in recent days.
"For the sake of democracy, if they don't want me to take part, I have no problem not taking part in new elections," Morales told Reuters in an interview in Mexico City.


The New Funko Hollywood Is an Essential Pop Culture Destination
by Germain LussierWe love Funko Pops. We write about them. We buy them. We’ve talked about them being decimated. We’ve even made a pilgrimage to Funko Headquarters in the US city of Everett, Washington to visit the flagship store. That place is incredibly epic, as it should be, but it doesn’t come close to touching the toy company’s new store in Hollywood, California.
Located mere feet from the legendary crossroads of Hollywood and Vine, Funko Hollywood opened last week and it’s jaw-dropping. At first, that might seem like an odd thing to say, because from the outside the place looks rather unassuming.
The entrance to Funko Hollywood.
Once inside, though, it’s anything but. You could get lost exploring its 40,000 square feet of nooks and crannies, especially as you walk by all the displays dedicated to basically every single major pop culture franchise or brand out there today. We’re talking Marvel, DC, Harry Potter, Little Mermaid, Frozen, Jurassic Park, Stranger Things, Game of Thrones, Rick and Morty, Friday the 13th, Halloween, It, Nightmare on Elm Street, Beetlejuice, Star Wars, Doctor Who, Nightmare Before Christmas, Aladdin, Mulan, Overwatch, Flintstones, Toy Story, and more. Yes, more.
Obviously, at each of these displays, you’ll find plenty of Funko Pops. However, as someone who collects Funko Pops, I have to say the selection and variety at each individual station isn’t particularly impressive. Most are just your run of the mill Funkos – stuff you can get anywhere. It’s an inventory catering more to passers-by than collectors. This makes sense, since the store is located in a very touristy area, but “overall selection” is the one category the Washington store beats this one in.
And yet, it doesn’t matter. Funko Hollywood is so overwhelming, buying something becomes secondary. The actual reason to visit is to take advantage of all of the pop-culture photo opportunities. They’re amazing. We’re talking life-size Funko versions of every one of those franchises listed above. Usually, more than one character too. Some of the brands even have multiple rooms (like Star Wars, Marvel, and DC) with elaborate sets for you to actually interact with. Others are just the characters standing around to pose with. And seriously, it’s just a nonstop feast for the eyes and your camera. Here’s just a sampling.
The Toy Story gang
Marvin the Martian
Oh Yeah!
Who doesn’t love Saturday morning cartoons?
Aladdin and his friends
Mulan and Mushu, waiting for the live-action movie.
The Doctor is in. Who? Exactly.
These aren’t the droids you’re looking for.
Do we even have to say it?

Float with Pennywise
Rick and Morty have made it to Hollywood.
Of course, Game of Thrones is there.
Strange things are afoot.
Must drive faster.
Into the Unknown, to buy some toys
Yes, the Suicide Squad Harley makes an appearance.
Release the Funko Pop!
Take a seat with the Hogwarts gang.
Snaps for this one.
Wakanda Forever!
And again, that’s just some of what you’ll find. If you’re in LA and into pop culture, a visit to Funko Hollywood is guaranteed to make you smile and snap way too many photos. Get more info on the Funko Facebook page.

Once upon a time there lived a man who dwelt with his wife in a little hut, far away from any neighbours. But they did not mind being alone, and would have been quite happy, if it had not been for a marten, who came every night to their poultry yard, and carried off one of their fowls. The man laid all sorts of traps to catch the thief, but instead of capturing the foe, it happened that one day he got caught himself, and falling down, struck his head against a stone, and was killed.
Not long after the marten came by on the look out for his supper. Seeing the dead man lying there, he said to himself: ‘That is a prize, this time I have done well’; and dragging the body with great difficulty to the sledge which was waiting for him, drove off with his booty. He had not driven far when he met a squirrel, who bowed and said: ‘Good-morning, godfather! what have you got behind you?’
The marten laughed and answered: ‘Did you ever hear anything so strange? The old man that you see here set traps about his hen-house, thinking to catch me but he fell into his own trap, and broke his own neck. He is very heavy; I wish you would help me to draw the sledge.’ The squirrel did as he was asked, and the sledge moved slowly along.
By-and-by a hare came running across a field, but stopped to see what wonderful thing was coming. ‘What have you got there?’ she asked, and the marten told his story and begged the hare to help them pull.
The hare pulled her hardest, and after a while they were joined by a fox, and then by a wolf, and at length a bear was added to the company, and he was of more use than all the other five beasts put together. Besides, when the whole six had supped off the man he was not so heavy to draw.
The worst of it was that they soon began to get hungry again, and the wolf, who was the hungriest of all, said to the rest:
‘What shall we eat now, my friends, as there is no more man?’
‘I suppose we shall have to eat the smallest of us,’ replied the bear, and the marten turned round to seize the squirrel who was much smaller than any of the rest. But the squirrel ran up a tree like lightning, and the marten remembering, just in time, that he was the next in size, slipped quick as thought into a hole in the rocks.
‘What shall we eat now?’ asked the wolf again, when he had recovered from his surprise.
‘We must eat the smallest of us,’ repeated the bear, stretching out a paw towards the hare; but the hare was not a hare for nothing, and before the paw had touched her, she had darted deep into the wood.
Now that the squirrel, the marten, and the hare had all gone, the fox was the smallest of the three who were left, and the wolf and the bear explained that they were very sorry, but they would have to eat him. Michael, the fox, did not run away as the others had done, but smiled in a friendly manner, and remarked: ‘Things taste so stale in a valley; one’s appetite is so much better up on a mountain.’ The wolf and the bear agreed, and they turned out of the hollow where they had been walking, and chose a path that led up the mountain side. The fox trotted cheerfully by his two big companions, but on the way he managed to whisper to the wolf: ‘Tell me, Peter, when I am eaten, what will you have for your next dinner?’
This simple question seemed to put out the wolf very much. What would they have for their next dinner, and, what was more important still, who would there be to eat it? They had made a rule always to dine off the smallest of the party, and when the fox was gone, why of course, he was smaller than the bear.
These thoughts flashed quickly through his head, and he said hastily:
‘Dear brothers, would it not be better for us to live together as comrades, and everyone to hunt for the common dinner? Is not my plan a good one?’
‘It is the best thing I have ever heard,’ answered the fox; and as they were two to one the bear had to be content, though in his heart he would much have preferred a good dinner at once to any friendship.
For a few days all went well; there was plenty of game in the forest, and even the wolf had as much to eat as he could wish. One morning the fox as usual was going his rounds when he noticed a tall, slender tree, with a magpie’s nest in one of the top branches. Now the fox was particularly fond of young magpies, and he set about making a plan by which he could have one for dinner. At last he hit upon something which he thought would do, and accordingly he sat down near the tree and began to stare hard at it.
‘What are you looking at, Michael?’ asked the magpie, who was watching him from a bough.
‘I’m looking at this tree. It has just struck me what a good tree it would be to cut my new snow-shoes out of.’ But at this answer the magpie screeched loudly, and exclaimed: ‘Oh, not this tree, dear brother, I implore you! I have built my nest on it, and my young ones are not yet old enough to fly.’
‘It will not be easy to find another tree that would make such good snow-shoes,’ answered the fox, cocking his head on one side, and gazing at the tree thoughtfully; ‘but I do not like to be ill-natured, so if you will give me one of your young ones I will seek my snow-shoes elsewhere.’
Not knowing what to do the poor magpie had to agree, and flying back, with a heavy heart, he threw one of his young ones out of the nest. The fox seized it in his mouth and ran off in triumph, while the magpie, though deeply grieved for the loss of his little one, found some comfort in the thought that only a bird of extraordinary wisdom would have dreamed of saving the rest by the sacrifice of the one. But what do you think happened? Why, a few days later, Michael the fox might have been seen sitting under the very same tree, and a dreadful pang shot through the heart of the magpie as he peeped at him from a hole in the nest.
‘What are you looking at?’ he asked in a trembling voice.
‘At this tree. I was just thinking what good snowshoes it would make,’ answered the fox in an absent voice, as if he was not thinking of what he was saying.
‘Oh, my brother, my dear little brother, don’t do that,’ cried the magpie, hopping about in his anguish. ‘You know you promised only a few days ago that you would get your snow-shoes elsewhere.’
‘So I did; but though I have searched through the whole forest, there is not a single tree that is as good as this. I am very sorry to put you out, but really it is not my fault. The only thing I can do for you is to offer to give up my snow-shoes altogether if you will throw me down one of your young ones in exchange.’
And the poor magpie, in spite of his wisdom, was obliged to throw another of his little ones out of the nest; and this time he was not able to console himself with the thought that he had been much cleverer than other people.
He sat on the edge of his nest, his head drooping and his feathers all ruffled, looking the picture of misery. Indeed he was so different from the gay, jaunty magpie whom every creature in the forest knew, that a crow who was flying past, stopped to inquire what was the matter. ‘Where are the two young ones who are not in the nest?’ asked he.
‘I had to give them to the fox,’ replied the magpie in a quivering voice; ‘he has been here twice in the last week, and wanted to cut down my tree for the purpose of making snow-shoes out of it, and the only way I could buy him off was by giving him two of my young ones.’
Oh, you fool,’ cried the crow, ‘the fox was only trying to frighten you. He could not have cut down the tree, for he has neither axe nor knife. Dear me, to think that you have sacrificed your young ones for nothing! Dear, dear! how could you be so very foolish!’ And the crow flew away, leaving the magpie overcome with shame and sorrow.
The next morning the fox came to his usual place in front of the tree, for he was hungry, and a nice young magpie would have suited him very well for dinner.
‘My good fox,’ said the magpie putting his head on one side and looking very wise—’my good fox, if you take my advice, you will go home as fast as you can. There is no use your talking about making snow-shoes out of this tree, when you have neither knife nor axe to cut it down with!’
‘Who has been teaching you wisdom?’ asked the fox, forgetting his manners in his surprise at this new turn of affairs.
‘The crow, who paid me a visit yesterday,’ answered the magpie.
‘The crow was it?’ said the fox, ‘well, the crow had better not meet me for the future, or it may be the worse for him.’
As Michael, the cunning beast, had no desire to continue the conversation, he left the forest; but when he came to the high road he laid himself at full length on the ground, stretching himself out, just as if he was dead. Very soon he noticed, out of the corner of his eye, that the crow was flying towards him, and he kept stiller and stiffer than ever, with his tongue hanging out of his mouth. The crow, who wanted her supper very badly, hopped quickly towards him, and was stooping forward to peck at his tongue when the fox gave a snap, and caught him by the wing. The crow knew that it was of no use struggling, so he said:
‘Ah, brother, if you are really going to eat me, do it, I beg of you, in good style. Throw me first over this precipice, so that my feathers may be strewn here and there, and that all who see them may know that your cunning is greater than mine.’ This idea pleased the fox, for he had not yet forgiven the crow for depriving him of the young magpies, so he carried the crow to the edge of the precipice and threw him over, intending to go round by a path he knew and pick him up at the bottom. But no sooner had the fox let the crow go than he soared up into the air, and hovering just out of reach of his enemy’s jaws, he cried with a laugh: ‘Ah, fox! you know well how to catch, but you cannot keep.’
With his tail between his legs, the fox slunk into the forest. He did not know where to look for a dinner, as he guessed that the crow would have flown back before him, and put every one on their guard. The notion of going to bed supperless was very unpleasant to him, and he was wondering what in the world he should do, when he chanced to meet with his old friend the bear.
This poor animal had just lost his wife, and was going to get some one to mourn over her, for he felt her loss greatly. He had hardly left his comfortable cave when he had come across the wolf, who inquired where he was going. ‘I am going to find a mourner,’ answered the bear, and told his story.
‘Oh, let me mourn for you,’ cried the wolf.
‘Do you understand how to howl?’ said the bear.
‘Oh, certainly, godfather, certainly,’ replied the wolf; but the bear said he should like to have a specimen of his howling, to make sure that he knew his business. So the wolf broke forth in his song of lament: ‘Hu, hu, hu, hum, hoh,’ he shouted, and he made such a noise that the bear put up his paws to his ears, and begged him to stop.
‘You have no idea how it is done. Be off with you,’ said he angrily.
A little further down the road the hare was resting in a ditch, but when she saw the bear, she came out and spoke to him, and inquired why he looked so sad. The bear told her of the loss of his wife, and of his search after a mourner that could lament over her in the proper style. The hare instantly offered her services, but the bear took care to ask her to give him a proof of her talents, before he accepted them. ‘Pu, pu, pu, pum, poh,’ piped the hare; but this time her voice was so small that the bear could hardly hear her. ‘That is not what I want,’ he said, ‘I will bid you good morning.’
It was after this that the fox came up, and he also was struck with the bear’s altered looks, and stopped. ‘What is the matter with you, godfather?’ asked he, ‘and where are you going?’
‘I am going to find a mourner for my wife,’ answered the bear.
‘Oh, do choose me,’ cried the fox, and the bear looked at him thoughtfully.
‘Can you howl well?’ he said.
‘Yes, beautifully, just listen,’ and the fox lifted up his voice and sang weeping: ‘Lou, lou, lou! the famous spinner, the baker of good cakes, the prudent housekeeper is torn from her husband!  But this did not suit the fox at all.
‘One cannot wail properly in this cave,’ he said, ‘it is much too damp. You had better take the body to the storehouse. It will sound much finer there.’ So the bear carried his wife’s body to the storehouse, while he himself went back to the cave to cook some pap for the mourner. From time to time he paused and listened for the sound of wailing, but he heard nothing. At last he went to the door of the storehouse, and called to the fox:
‘Why don’t you howl, godfather? What are you about?’
And the fox, who, instead of weeping over the dead bear, had been quietly eating her, answered:
‘There only remain now her legs and the soles of her feet. Give me five minutes more and they will be gone also!’
When the bear heard that he ran back for the kitchen ladle, to give the traitor the beating he deserved. But as he opened the door of the storehouse, Michael was ready for him, and slipping between his legs, dashed straight off into the forest. The bear, seeing that the traitor had escaped, flung the ladle after him, and it just caught the tip of his tail, and that is how there comes to be a spot of white on the tails of all foxes.

--- layout: post title: "A Success Story from KAUST" authors: ["Tareq Malas"] date: 2014-06-15 time: "18:00:00" tags: ["Bootcamps", "King Abdullah University of Science and Technology"] ---
Our ACM student chapter at King Abdullah University of Science and Technology (KAUST) is active in supporting the diverse research community at our university. We decided to offer Python tutorials to our community by the end of 2013. Due to no information on the background and interests of KAUST community, we crafted a short survey to help us in tailoring our tutorials. The following image shows the summary of the responses we got:
We focused on two areas in the survey; Programming level and applications interest. We prepared a week-long workshop during February 23-27, offering seven sessions on Python tutorials. The workshop was greatly accepted by university community; we had full registration in few hours and we had 40-50 registration in each session.
It is worth mentioning that the timing of the tutorials was carefully selected to maximize the graduate students registration. Classes start early February, where the students usually attend extra classes in the first two weeks to decide which courses to keep or drop. If we offered our tutorials after February, we would had less attendance because classes mid-terms and projects pressure starts till the end of the semester. These facts motivated us to select the last week of February to offer our tutorials, where the students are least busy and available on campus.
We believe that making the tutorial hands-on was an important choice. The attendants were specialized in different fields: Chemistry, Biology, Computer Science, etc. They had different programming background. This made it difficult to find a suitable pace in these tutorials.
The responses we received in our feedback survey after the tutorials were generally satisfactory. If you would like to know more, please check out our tutorial webpage.

Once you eliminate your number one problem, number two gets a promotion.
G.Weinberg
This problem is taken from the book "Introduction to Algorithms" by C.L.R.S. , a very tough and long book, but still
deemed the bible of Algorithms.
Let's quote the text:
Each of n customer gives a hat to a hat-check person at a restaurant. The hat-check person gives the hats back to the customers
in a random order. What is the expected number of customers who get back their own hat?
Let's neglect the mathematical proof and try to figure out how we can solve the problem with more of a "coding" approach.
The first idea is that each person corresponds to a unique hat. So a dictionary object seems perfect to work on it.
The second thing is that we need a random generator, so we will import the random module and we'll use the choice(seq) method.
This method returns a single element randomly chosen in a certain sequence that is the argument of the method.
Eventually, we employ a Monte Carlo simulation (in other words: we repeat the test N times, where N is a large number, in
order to fulfill the law of large numbers) to arrive at outcome.
Let's see the code:
We create a dictionary of seven people in our example. We assign a hat of a given color to each person. In our example a color is a unique label, so every color is different from the others. Before every nested loop we create the list with the colours of the dictionary. As you can notice, for each test, we increase the count only if the random.choice method returns the same color of the key dictionary (see #line 12). Otherwise we continue the loop without increasing the counter. In line 14 we remove from the sequence of iterable colors the color randomly chosen in that step. When we iterate the last key of the dictionary (the customer's name), necessarily len(r) will be == 1, because the number of remaining people and number of iterable colors coincide.
At the end of every nested loop (the single test) we update the total variable by adding the count variable. When all the 100000 tests will finish, the outcome will be the ratio between total and N.The output:
The expected number of customers who get back their own hat is: 1.00738
So, on average, only one person will get back their own hat.
Ok....but...what happens if we change the number of people? Now we have only 7 people...what if we build a dictionary
of 10, 100 or 1000 different persons paired with 10, 100, 1000 different hats?
...
Nothing. The outcome is always 1. It is independent of the number n of people.
If you don't believe me, change the code in your editor by adding more items in dictionary and let me know...
Strangeness of Math ;)
(You can find somewhere on the Web the mathematical proof where the result is 1. With a Monte Carlo simulation
we will converge towards the exact result but for every simulation we will obtain a slightly different result obviously).

ConnectDrakeVisualizer
(*args, **kwargs)¶ Overloaded function.
- ConnectDrakeVisualizer(builder: pydrake.systems.framework.DiagramBuilder_[float], scene_graph: pydrake.geometry.SceneGraph, lcm: pydrake.lcm.DrakeLcmInterface = None) -> pydrake.systems.lcm.LcmPublisherSystem
Extends a Diagram with the required components to interface with drake_visualizer. This must be called during Diagram building and uses the given
builder
to add relevant subsystems and connections.This is a convenience method to simplify some common boilerplate for adding visualization capability to a Diagram. What it does is:
- adds an initialization event that sends the required load message to set up
the visualizer with the relevant geometry, - adds systems PoseBundleToDrawMessage and LcmPublisherSystem to the Diagram and connects the draw message output to the publisher input, - connects the
scene_graph
pose bundle output to the PoseBundleToDrawMessage system, and - sets the publishing rate to 1/60 of a second (simulated time).The visualization mechanism depends on the illustration role (see geometry_roles for details). Specifically, only geometries with the illustration role assigned will be included. The visualization function looks for the following properties in the IllustrationProperties instance. | Group name | Required | Property Name | Property Type | Property Description | | :——–: | :——: | :———–: | :————-: | :——————- | | phong | no | diffuse | Eigen::Vector4d | The rgba value of the object surface | See MakeDrakeVisualizerProperties() to facilitate making a compliant set of illustration properties.
You can then connect source output ports for visualization like this:
builder->Connect(pose_output_port, scene_graph.get_source_pose_port(source_id));
Note
The initialization event occurs when Simulator::Initialize() is called (explicitly or implicitly at the start of a simulation). If you aren’t going to be using a Simulator, use DispatchLoadMessage() to send the message yourself.
- Parameter
builder
: - The diagram builder being used to construct the Diagram.
- Parameter
scene_graph
: - The System in
builder
containing the geometry to be visualized. - Parameter
lcm
: - An optional lcm interface through which lcm messages will be dispatched. Will be allocated internally if none is supplied.
- Precondition:
- This method has not been previously called while building the builder’s current Diagram.
- Precondition:
- The given
scene_graph
must be contained within the supplied DiagramBuilder.
Returns: the LcmPublisherSystem (in case callers, e.g., need to change the default publishing rate). See also
geometry::DispatchLoadMessage()
- ConnectDrakeVisualizer(builder: pydrake.systems.framework.DiagramBuilder_[float], scene_graph: pydrake.geometry.SceneGraph, pose_bundle_output_port: pydrake.systems.framework.OutputPort_[float], lcm: pydrake.lcm.DrakeLcmInterface = None) -> pydrake.systems.lcm.LcmPublisherSystem
Implements ConnectDrakeVisualizer, but using
pose_bundle_output_port
to explicitly specify the output port used to get pose bundles forscene_graph
. This is required, for instance, when the SceneGraph is inside a Diagram, and the Diagram exports the pose bundle port.- Precondition:
- pose_bundle_output_port must be connected directly to the
pose_bundle_output_port of
scene_graph
.
See also
ConnectDrakeVisualizer().
-
pydrake.geometry.
DispatchLoadMessage
(scene_graph: pydrake.geometry.SceneGraph, lcm: pydrake.lcm.DrakeLcmInterface) → None¶ (Advanced) Explicitly dispatches an LCM load message based on the registered geometry. Normally this is done automatically at Simulator initialization. But if you have to do it yourself (likely because you are not using a Simulator), it should be invoked after registration is complete. Typically this is used after ConnectDrakeVisualizer() has been used to add visualization to the Diagram that contains the given
scene_graph
. The message goes to LCM channel “DRAKE_VIEWER_LOAD_ROBOT”.See also

QueryObject
¶ The QueryObject serves as a mechanism to perform geometry queries on the world’s geometry. The SceneGraph has an abstract-valued port that contains a QueryObject (i.e., a QueryObject-valued output port).
To perform geometry queries on SceneGraph: - a LeafSystem must have a QueryObject-valued input port and connect it to the corresponding query output port on SceneGraph, - the querying LeafSystem can evaluate the input port, retrieving a
const QueryObject&
in return, and, finally, - invoke the appropriate method on the QueryObject.The const reference returned by the input port is considered “live” - it is linked to the context, system, and cache (making full use of all of those mechanisms). This const reference should never be persisted; doing so can lead to erroneous query results. It is simpler and more advisable to acquire it for evaluation in a limited scope (e.g., CalcTimeDerivatives()) and then discard it. If a QueryObject is needed for many separate functions in a LeafSystem, each should re-evaluate the input port. The underlying caching mechanism should make the cost of this negligible.
In addition to not persisting the reference from the output port, the QueryObject shouldn’t be copied. Strictly speaking, it is an allowed operation, but the result is not live, and any geometry query performed on the copy will throw an exception.
A QueryObject cannot be converted to a different scalar type. A QueryObject of scalar type S can only be acquired from the output port of a SceneGraph of type S evaluated on a corresponding GeometryContext, also of type S.
- Template parameter
T
: - The scalar type. Must be a valid Eigen scalar.
Instantiated templates for the following kinds of T’s are provided:
- double

They are already available to link against in the containing library. No other values for T are currently supported.

ComputePointPairPenetration
(self: pydrake.geometry.QueryObject) → List[drake::geometry::PenetrationAsPointPair<double>]¶ Computes the penetrations across all pairs of geometries in the world. Only reports results for penetrating geometries; if two geometries are separated, there will be no result for that pair. Pairs of anchored geometry are also not reported. The penetration between two geometries is characterized as a point pair (see PenetrationAsPointPair).
For two penetrating geometries g₁ and g₂, it is guaranteed that they will map to
id_A
andid_B
in a fixed, repeatable manner.This method is affected by collision filtering; element pairs that have been filtered will not produce contacts, even if their collision geometry is penetrating.
Returns: A vector populated with all detected penetrations characterized as point pairs.
-
ComputeSignedDistancePairwiseClosestPoints
(self: pydrake.geometry.QueryObject) → List[drake::geometry::SignedDistancePair<double>]¶ Computes the signed distance together with the nearest points across all pairs of geometries in the world. Reports both the separating geometries and penetrating geometries.
This query provides φ(A, B), the signed distance between two objects A and B.
If the objects do not overlap (i.e., A ⋂ B = ∅), φ > 0 and represents the minimal distance between the two objects. More formally: φ = min(|Aₚ - Bₚ|) ∀ Aₚ ∈ A and Bₚ ∈ B.
Note
The pair (Aₚ, Bₚ) is a “witness” of the distance. The pair need not be unique (think of two parallel planes).
If the objects touch or overlap (i.e., A ⋂ B ≠ ∅), φ ≤ 0 and can be interpreted as the negative penetration depth. It is the smallest length of the vector v, such that by shifting one object along that vector relative to the other, the two objects will no longer be overlapping.  By implication, there exist points Aₚ and Bₚ on the surfaces of objects A and B, respectively, such that Aₚ + v = Bₚ, Aₚ ∈ A ∩ B, Bₚ ∈ A ∩ B. These points are the witnesses to the penetration.
This method is affected by collision filtering; geometry pairs that have been filtered will not produce signed distance query results.
Notice that this is an O(N²) operation, where N is the number of geometries remaining in the world after applying collision filter. We report the distance between dynamic objects, and between dynamic and anchored objects. We DO NOT report the distance between two anchored objects.

SceneGraph
¶ Bases:
pydrake.systems.framework.LeafSystem_[float]
SceneGraph serves as the nexus for all geometry (and geometry-based operations) in a Diagram. Through SceneGraph, other systems that introduce geometry can register that geometry as part of a common global domain, including it in geometric queries (e.g., cars controlled by one LeafSystem can be observed by a different sensor system). SceneGraph provides the interface for registering the geometry, updating its position based on the current context, and performing geometric queries.
Only registered “geometry sources” can introduce geometry into SceneGraph. Geometry sources will typically be other leaf systems, but, in the case of anchored (i.e., stationary) geometry, it could also be some other block of code (e.g., adding a common ground plane with which all systems’ geometries interact). For dynamic geometry (geometry whose pose depends on a Context), the geometry source must also provide pose values for all of the geometries the source owns, via a port connection on SceneGraph.
The basic workflow for interacting with SceneGraph is:
- Register as a geometry source, acquiring a unique SourceId.
- Register geometry (anchored and dynamic) with the system.
- Connect source’s geometry output ports to the corresponding SceneGraph
input ports. - Implement appropriate
Calc*
methods on the geometry output ports to update geometry pose values.For each registered geometry source, there is one input port for each order of kinematics values (e.g., pose, velocity, and acceleration). If a source registers a frame, it must connect to these ports (although, in the current version, only pose is supported). Failure to connect to the port (or to provide valid kinematics values) will lead to runtime exceptions.
pose port: An abstract-valued port providing an instance of FramePoseVector. For each registered frame, this “pose vector” maps the registered FrameId to a pose value. All registered frames must be accounted for and only frames registered by a source can be included in its output port. See the details in FrameKinematicsVector for details on how to allocate and calculate this port.
SceneGraph has two output ports:
query port: An abstract-valued port containing an instance of QueryObject. It provides a “ticket” for downstream LeafSystem instances to perform geometric queries on the SceneGraph. To perform geometric queries, downstream LeafSystem instances acquire the QueryObject from SceneGraph’s output port and provide it as a parameter to one of SceneGraph’s query methods (e.g., SceneGraph::ComputeContact()). This assumes that the querying system has access to a const pointer to the connected SceneGraph instance. Use get_query_output_port() to acquire the output port for the query handle.
lcm visualization port: An abstract-valued port containing an instance of PoseBundle. This is a convenience port designed to feed LCM update messages to drake_visualizer for the purpose of visualizing the state of the world’s geometry. Additional uses of this port are strongly discouraged; instead, use an appropriate geometric query to obtain the state of the world’s geometry.
LeafSystem instances can relate to SceneGraph in one of two ways: as a consumer that performs queries, or as a producer that introduces geometry into the shared world and defines its context-dependent kinematics values. It is reasonable for systems to perform either role singly, or both.
Consumer
Consumers perform geometric queries upon the world geometry. SceneGraph serves those queries. As indicated above, in order for a LeafSystem to act as a consumer, it must: 1. define a QueryObject-valued input port and connect it to SceneGraph’s corresponding output port, and 2. have a reference to the connected SceneGraph instance.
With those two requirements satisfied, a LeafSystem can perform geometry queries by: 1. evaluating the QueryObject input port, and 2. passing the returned query object into the appropriate query method on SceneGraph (e.g., SceneGraph::ComputeContact()).
Producer
All producers introduce geometry into the shared geometric world. This is called registering geometry. Depending on what exactly has been registered, a producer may also have to update kinematics. Producers themselves must be registered with SceneGraph as producers (a.k.a. geometry sources). They do this by acquiring a SourceId (via SceneGraph::RegisterSource()). The SourceId serves as a unique handle through which the producer’s identity is validated and its ownership of its registered geometry is maintained.
Registering Geometry
SceneGraph cannot know what geometry should be part of the shared world. Other systems are responsible for introducing geometry into the world. This process (defining geometry and informing SceneGraph) is called registering the geometry. The source that registers the geometry “owns” the geometry; the source’s unique SourceId is required to perform any operations on the geometry registered with that SourceId. Geometry can be registered as anchored or dynamic.
Dynamic geometry can move; more specifically, its kinematics (e.g., pose) depends on a system’s Context. Particularly, dynamic geometry is fixed to a frame whose kinematics values depend on a context. As the frame moves, the geometries fixed to it move with it. Therefore, to register dynamic geometry a frame must be registered first. These registered frames serve as the basis for repositioning geometry in the shared world. The geometry source is responsible for providing up-to-date kinematics values for those registered frames upon request (via an appropriate output port on the source LeafSystem connecting to the appropriate input port on SceneGraph). The work flow is as follows: 1. A LeafSystem registers itself as a geometry source, acquiring a SourceId (RegisterSource()). 2. The source registers a frame (GeometrySource::RegisterFrame()). - A frame always has a “parent” frame. It can implicitly be the world frame, or another frame registered by the source. 3. Register one or more geometries to a frame (GeometrySource::RegisterGeometry()). - The registered geometry is posed relative to the frame to which it is fixed. - The geometry can also be posed relative to another registered geometry. It will be affixed to that geometry’s frame.
Anchored geometry is independent of the context (i.e., it doesn’t move). Anchored geometries are always affixed to the immobile world frame. As such, registering a frame is not required for registering anchored geometry (see GeometrySource::RegisterAnchoredGeometry()). However, the source still “owns” the anchored geometry.
Updating Kinematics
Registering dynamic geometry implies a contract between the geometry source and SceneGraph. The geometry source must do the following: - It must provide, populate, and connect two output ports: the “id” port and the “pose” port. - The id port must contain all the frame ids returned as a result of frame registration. - The pose port must contain one pose per registered frame; the pose value is expressed relative to the registered frame’s parent frame. As mentioned above, the iᵗʰ pose value should describe the frame indicated by the iᵗʰ id in the id output port.
Failure to meet these requirements will lead to a run-time error.
Many (and eventually all) methods that configure the population of SceneGraph have two variants that differ by whether they accept a mutable Context or not. When no Context is provided, this SceneGraph instance’s underlying model is modified. When the SceneGraph instance allocates a context, its model is copied into that context.
The second variant causes SceneGraph to modify the data stored in the provided Context to be modified instead of the internal model.
Note
In this initial version, the only methods with the Context-modifying variant are those methods that do not change the the semantics of the input or output ports. Modifications that make such changes must be coordinated across systems.

T
: - The scalar type. Must be a valid Eigen scalar.
Instantiated templates for the following kinds of T’s are provided:

RegisterSource
(self: pydrake.geometry.SceneGraph, name: unicode = u'') → pydrake.geometry.SourceId¶ Registers a new source to the geometry system. The caller must save the returned SourceId; it is the token by which all other operations on the geometry world are conducted.
This source id can be used to register arbitrary anchored geometry. But if dynamic geometry is registered (via RegisterGeometry/RegisterFrame), then the context-dependent pose values must be provided on an input port. See get_source_pose_port().
- Parameter
name
: - The optional name of the source. If none is provided (or the empty string) a unique name will be defined by SceneGraph’s logic.
Raises: - RuntimeError if a context has already been allocated for this
SceneGraph.

SceneGraphInspector
¶ The SceneGraphInspector serves as a mechanism to query the topological structure of a SceneGraph instance. The topological structure consists of all of the SceneGraph data that does not depend on input pose data. Including, but not limited to:
- names of frames and geometries
- hierarchies (parents of geometries, parents of frames, etc.)
- geometry parameters (e.g., contact, rendering, visualization)
- fixed poses of geometries relative to frames
In contrast, the following pieces of data do depend on input pose data and cannot* be performed with the SceneGraphInspector (see the QueryObject instead):
- world pose of frames or geometry
- collision queries
- proximity queries
A SceneGraphInspector cannot be instantiated explicitly. Nor can it be copied or moved. A reference to a SceneGraphInspector instance can be acquired from
- a SceneGraph instance (to inspect the state of the system’s model), or
- a QueryObject instance (to inspect the state of the scene graph data stored
in the context).
The reference should not be persisted (and, as previously indicated, cannot be copied). SceneGraphInspector instances are cheap; they can be created, queried, and thrown out. If there is any doubt about the valid lifespan of a SceneGraphInspector, throw out the old instance and request a new instance.
- Template parameter
T
: - The scalar of the associated SceneGraph instance. The template parameter is provided for the sake of compatibility, although no queries (or their results) depend on the scalar.

Grid lists are an alternative to standard list views. Grid lists are distinct from grids used for layouts and other visual presentations.
A grid list is best suited to presenting a homogenous data type, typically images, and is optimized for visual comprehension and differentiating between like data types.
A grid list is a continuous element consisting of tessellated, regular
subdivisions called cells that contain tiles (md-grid-tile
).
Cells are arrayed vertically and horizontally within the grid.
Tiles hold content and can span one or more cells vertically or horizontally.
The md-grid-list
directive supports "responsive" attributes, which allow
different md-cols
, md-gutter
and md-row-height
values depending on the
currently matching media query.
In order to set a responsive attribute, first define the fallback value with
the standard attribute name, then add additional attributes with the
following convention: {base-attribute-name}-{media-query-name}="{value}"
(ie. md-cols-lg="8"
)

Privilege motion submitted against Khawaja Asif in National Assembly | Pakistan - Geo.tv
by Web DeskISLAMABAD: Minister for Science and Technology Fawad Chaudhry on Saturday submitted a privilege motion against Pakistan Muslim League-Nawaz (PML-N) leader Khawaja Muhammad Asif.
Chaudhry filed the motion against Asif for his “misrepresentation of truth on the floor of the House, which was tantamount to a breach of the privilege of the entire House.”
“Khawaja Muhammad Asif quoted the representatives of the federal government and those of the Government of Punjab, as saying ‘let Nawaz Sharif die’, which is a vivid misrepresentation of truth and of the decision of the Honourable Islamabad High Court regarding the interim bail of Nawaz Sharif on medical grounds.”
The motion further pointed out, that the detailed judgement by IHC “outrightly negates the statement of Khawaja Asif which he made on the floor of the House and that it is clear breach of the privilege of the entire House.”
The federal minister requested that statement made by the PML-N leader should be taken up for discussion and may be sent to the Standing Committee on Rules of Procedures for further action.
