Analysis
This is an extremely difficult question.
The idea of the solution (using stack) seems understandable, but can be very tricky when coding.
The basic idea is, always keep increasing elements in the stack. When I see a decrease in number, pop stack. And I calculate max area only when poping elements. In the end, a ‘0’ is inserted to the end, so that all stack item will be popped (and at the same time, max area been calculated).
Sorry if I did not explain well enough. Here is a better one:
We traverse all bars from left to right, maintain a stack of bars. Every bar is pushed to stack once. A bar is popped from stack when a bar of smaller height is seen. When a bar is popped, we calculate the area with the popped bar as smallest bar. How do we get left and right indexes of the popped bar – the current index tells us the ‘right index’ and index of previous item in stack is the ‘left index’. Following is the complete algorithm.
1) Create an empty stack.
2) Start from first bar, and do following for every bar ‘hist[i]‘ where ‘i’ varies from 0 to n-1.
……a) If stack is empty or hist[i] is higher than the bar at top of stack, then push ‘i’ to stack.
……b) If this bar is smaller than the top of stack, then keep removing the top of stack while top of the stack is greater. Let the removed bar be hist[tp]. Calculate area of rectangle with hist[tp] as smallest bar. For hist[tp], the ‘left index’ is previous (previous to tp) item in stack and ‘right index’ is ‘i’ (current index).3) If the stack is not empty, then one by one remove all bars from stack and do step 2.b for every removed bar.
Time complexity of the stack solution is O(n). (Another algo analysis article here)
Solution
I wrote the code using idea from blog. It works, but there are 2 things that I got wrong.
First, if elements are equal. I shall also push it. I can not simply skip it, I don’t know why!
if (stack.isEmpty() || cur >= height[stack.peek()])
Second, about how to calculate the width of the rectangle. I used this before:
int width = stack.isEmpty() ? p : p - h;
It’s wrong, I must get the value of next element from stack, and then calculate width. Why? there might be element been popped before, which locate between these 2 elements in stack.
int width = stack.isEmpty() ? p : p - stack.peek() - 1;
Updated on July 4th, 2014: the above 2 points are very valid, especially the second. Keep in mind:
The values in stack means the last position that a height can be found. For example, height is (2, 10, 5) then the stack would have (2, removed, 5). When calculating the area for height 5, we should note the removed space is in consideration as well.
So, when equal height is found, pop it. Because you won’t need it any more. The stack only stores last position this height is found.
When stack is empty, the width of rectange should be calculated from 0.

For AutoAuth to be able to fill in your credentials automatically you need to enter them here. For further details why this is necessary see below.
With Firefox 57 old fashioned extensions are disabled. Only addons based on WebExtensions are allowed. Before this addon basically waited for Firefox' modal window asking for your password and automatically hit enter for you. With the new WebExtensions interface this is not possible anymore. Instead the addon now intercepts responses that need basic authentication and send your credentials automatically.
Unfortinatly there is no API yet to access these passwords. Thus AutoAuth needs to save the credentials itself.
Your passwords are stored unencrypted, as there does not exist an API to derive an encryption key. Asking for an encryption password each time the addon is used would defeat it's purpose. The passwords are stored in the same directory Firefox stores its passwords and is thus equally secure if you do not use a master password.

A person that is in outpatient mental heath treatment do not have to stay in a building. You visit theripist offices often.
Outpatient mental illness treatment is best suited for those with: Mild to moderate symptoms, A solid support system, and The ability to function outside of the treatment environment.
-
A person might be in this program because they are a danger to themself or others
A person is a candidate for psychiatric hospitalization when they have Severe mental health symptoms, Hallucinations or delusions, Suicidal or homicidal ideation, Not slept or eaten for days, or Lost the ability to care for themselves due to mental health symptoms.
-
This is needed if reletively severe or long-term syndrome and lives in that building with constant 24/7 supervision.
Mental illness treatment at an inpatient facility typically consists of the following types of treatment: Individual psychotherapy/counseling Group therapy, Medication, Medical supervision, Recreational therapies, and Complementary therapies (e.g., yoga or meditation).
-
Dual diagnosis treatment is used if you have a mental illness and addition or an substance use disorder.
Both disorders need to be treated simultaneously to maximize the chances of a full recovery.
-
Psychotherapy is when the person goes to a group and talk about there situation.
There are many forms of psychotherapy one is individual therapy. Individual therapy is a form of talk therapy where an individual works one on one with a therapist to address unresolved feelings, traumas, and mental health problems using a variety of different strategies and approaches.
-
Medication can be subscribbed to to help with the symptoms of the mental illness
Just like psychotherapy, medication has many forms and one of them are mood stabilizers are commonly prescribed for people with bipolar disorder and related mood disorders to stabilize mood and prevent significant mood swings, mania, and depression.
-
a 12-step program and/or support groups works with medication and psychotherapy because it may be good complementary therapies for people who are undergoing psychotherapy and/or taking medication.
People might go throught this program if they have Alcohol abuse, Drug abuse. Gambling, shopping, video gaming, and other behavioral addictions. Anxiety and depression or Eating disorders.
-
Complementary and alternative mental health treatment options may be used in addition to traditional forms of treatment such as therapy and medication.
One complementary treatment is exercise is also an important component of mental health treatment. People suffering from mental health conditions should attempt to do some form of exercise for at least 30 minutes each day to decrease stress.

Gene Ontology Term Data Visualization
Cytoscape is an open source software platform for integrating, visualizing, and analyzing measurement data in the context of networks.
This protocol includes a basic workflow for visualizing experimental data on a Gene Ontology term of interest in Cytoscape:
- Retrieve genes associated with a GO term
- Retrieving relevant interactions from public databases
- Integration and visualization of experimental data
- Exporting network visualizations
Setup
- Install the stringApp via Apps → App Manager.
- Download the experimental data (follow the link and on the page, right-click and select Save As...).
The data is a lung cancer dataset from TCGA, comparing lung cancer biopses versus normal tissue.
Retrieveing Gene Ontology Term Genes
From enrichment analysis, we know that some Gene Ontology Biological Process terms are enriched in this data. We will choose one of these terms for visualization, GO:1902850; microtubule cytoskeleton organization involved in mitosis.
- Go to the AmiGO browser and search for GO:1902850 using the Quick search field.
- On the results page, click the link for genes and gene products. This will show associated genes for all organisms.
Retrieveing Gene Ontology Term Genes
- On the left side, click Organism to expand and then click the green plus sign next to Homo sapiens. At the top of the gene list, the number of Total gene products should now be around 148.
- Click the Custom DL button. In the popup, drag the top entry, Gene/product (bioentity), to the left, to exclude it from the download. Click Download.
- On the page that opens, select and copy the list of gene symbols. It is also a good idea to save the list by pasting it into any text editor.
STRING GO Term Network
The resulting network represents genes associated with the GO term, recognized by STRING, and interactions between them with an confidence score of 0.8 or greater.
Data Integration
Next we will import the data to create a visualization.
- Load the downloaded lung.expr.csv file under File menu by selecting Import → Table from File..... Alternatively, drag and drop the data file directly onto the Node Table.
- Select the display name column as the Key column for Network and select the GeneName column as the key column by clicking on the header and selecting the key symbol.
- Click OK to import. Two new columns of data will be added to the Node Table.
Visualization
Next, we will create a visualization of the imported data on the network. For more detailed information on data visualization, see the Visualizing Data tutorial.
- Go to the STRING Results Panel to the right of the network and uncheck Glass ball effect and STRING style colors. This will make the nodes
- Set the default Border Width to 2, and make the default Border Paint dark gray.
- Set the default node Label Font Size to 14.
Visualization
- For node Fill Color, create a continuous mapping for Log2FC.
- Save your new visualization under Copy Style... in the Options menu of the Style interface, and name it de genes up.
- Looking at only the largest connected component of the network (ignoring unconnected nodes), the network now looks like this:
Layout
We can change the layout of the network to see if we can improve the visualization.
- Apply the Prefuse Force Directed layout by clicking the Apply Preferred Layout button in the toolbar. The network will now look something like this:
Layout
The network has a highly connected group of nodes that appear to be upreuglated. We can alter the layout settings slightly to increase the readability:
- Select Layout → Settings to open the Layout Settings dialog.
- Make sure Prefuse Force Directed Layout is selected in the drop-down at the top. Change the Default Spring Length to 80. Click Apply Layout.
Exporting Networks
Cytoscape provides a number of ways to export results and visualizations:
- As an image: File → Export → Network to Image...
- To NDEx: Click the NDEx button in the toolbar and select Export Network to NDEx. Alternatively, select File → Export → Network to NDEx, or File → Export → Collection to NDEx
- As a Cytoscape JSON file: File → Export → Network to File and select Cytoscape.js JSON as the format.


WHiSe II is a symposium aimed at strengthening communication between scholars in the Digital Humanities and Semantic Web communities and discussing unthought-of opportunities arising from the research problems of the former. Its best-of-both-worlds format will accommodate the practices of scholarly dialogue in both fields by inviting visions, real systems and debate.
WHiSe is proudly co-located with the 16th International Semantic Web Conference (ISWC)
Large digital libraries and cultural heritage aggregators have demonstrated the value of semantic technologies in the dissemination of catalogued data in the Humanities, also thanks to widely-adopted extensible conceptual models. However, the more recent digital research landscape in the Humanities has seen the rise of a multitude of application domains for Linked Data management techniques and Web ontologies, including the production of gazetteers and other concept schemes, annotated historical documents and even digital preservation of the intangible aspects of cultural, such as the performing arts.
As this emerging research ecosystem deals with the reality of the Semantic Web and the ever-growing data cloud under its aegis, it is important to reflect on the ways in which the Semantic Web community is serving the needs of these research networks which include historians, philologists, cultural critics, musicologists and artists. Are barriers to access to these systems and techniques inhibiting uptake in these scholarly areas? Are there research challenges of interest that humanists have not considered due to biased perceptions as to the utility of Linked Data? What problems do Humanities users experience when interacting with Semantic Web content and applications? What otherwise unseen opportunities might arise by confronting Semantic Web researchers with non-technical issues and needs stemming from cultural studies?
WHiSe II welcomes original research contributions crossing Humanities and the Semantic Web. Scholars who have conducted research or developed impactful applications are invited to submit full papers with appropriately evaluated contributions. WHiSe II also welcomes short vision or position papers on novel challenges or approaches to existing problems.
Topics on which potential submitters are invited to contribute include, but are not limited to:
Submissions in all the categories mentioned above (both full and short papers) will be peer-reviewed by acknowledged researchers familiar with both scientific communities. Accepted papers will be published as online proceedings courtesy of CEUR-WS.org.
Papers will be evaluated according to their significance, originality, technical content, style, clarity, and relevance to the workshop.
We welcome the following types of contributions:
All submissions must be PDF documents written in English and formatted according to LNCS instructions for authors.
Papers are to be submitted through the Easychair Conference Management System. Page limits are inclusive of references and appendices, if any.
Every submitted paper must represent original and unpublished work: it must not be under review or accepted elsewhere and there must be a significantly clear element of novelty distinguishing a submitted paper from any other prior publication or current submission. See also the guidelines of the ISWC 2017 research track.

--- layout: post title: "Object isomorphisms" description: "An object is equivalent to a product of functions. Alternative ways to look at objects." date: 2018-02-12 19:34 UTC tags: [Software Design] --- {% include JB/setup %}
{{ page.description }}
This article is part of a series of articles about software design isomorphisms. So far, you've seen how to represent a single method or function in many different ways, but we haven't looked much at objects (in the object-oriented interpretation of the word).
While this article starts by outlining the abstract concepts involved, an example is included towards the end.
I often use the phrase that objects are data with behaviour. (I'm sure I didn't come up with this myself, but the source of the phrase escapes me.) In languages like C# and Java, objects are described by classes, and these often contain class fields. These fields constitute an instance's data, whereas its methods implement its behaviour.
A class can contain an arbitrary number of fields, just like a method can take an arbitrary number of arguments. As demonstrated by the argument list isomorphisms, you can also represent an arbitrary number of arguments as a Parameter Object. The same argument can be applied to class fields. Instead of n fields, you can add a single 'data class' that holds all of these fields. In F# and Haskell these are called records. You could also dissolve such a record to individual fields. That would be the inverse refactoring, so these representations are isomorphic.
In other words, a class looks like this:
public class Class1 { public Data1 Data { get; set; } public Out1 Op1(In1 arg) { // Do stuff with this, Data, and arg; return an Out1 value. } public Out2 Op2(In2 arg) { // Do stuff with this, Data, and arg; return an Out1 value. } public Out3 Op3(In3 arg) { // Do stuff with this, Data, and arg; return an Out1 value. } // More members... }
Instead of an arbitrary number of fields, I've used the above isomorphism to represent data in a single Data
property (Java developers: a C# property is a class field with public getter and setter methods).
In this code example, I've deliberately kept the naming abstract. The purpose of this article series is to look at the shape of code, instead of what it does, or why. From argument list isomorphisms we know that we can represent any method as taking a single input value, and returning a single output value. The remaining work to be done in this article is to figure out what to do when there's more than a single method.
From function isomorphisms we know that static methods are isomorphic to instance methods, as long as you include the original object as an extra argument. In this case, all data in Class1
is contained in a single (mutable) Data1
record, so we can eliminate Class1
from the argument list in favour of Data1
:
public static class Class1 { public static Out1 Op1(Data1 data, In1 arg) { // Do stuff with data and arg; return an Out1 value. } public static Out2 Op2(Data1 data, In2 arg) { // Do stuff with data and arg; return an Out1 value. } public static Out3 Op3(Data1 data, In3 arg) { // Do stuff with data and arg; return an Out1 value. } // More members... }
Notice that Class1
is now a static
class. This simply means that it has no instance members, and if you try to add one, the C# compiler will complain.
This is, in essence, a module. In F#, for example, a module
is a static class that contains a collection of values and functions.
As data with behaviour, objects are often passed around as input to methods. It's a convenient way to pass both data and associated behaviour (perhaps even with polymorphic dispatch) as a single thing. You'd be forgiven if you've looked at the above module-style refactoring and found it lacking in that regard.
Nevertheless, function isomorphisms already demonstrated that you can solve this problem with closures. Imagine that you want to package all the static methods of Class1
with a particular Data1
value, and pass that 'package' as a single argument to another method. You can do that by closing over the value:
var data = new Data1 { /* initialize members here */ }; Func<In1, Out1> op1 = arg => Class1.Op1(data, arg); Func<In2, Out2> op2 = arg => Class1.Op2(data, arg); Func<In3, Out3> op3 = arg => Class1.Op3(data, arg); // More closures...
First, you create a Data1
value, and initialise it with your desired values. You then create op1
, op2
, and so on. These are functions that close over data
; A.K.A. closures. Notice that they all close over the same variable. Also keep in mind here that I'm in no way pretending that data
is immutable. That's not a requirement.
Now you have n closures that all close over the same data
. All you need to do is to package them into a single 'object':
var objEq = Tuple.Create(op1, op2, op3 /* more closures... */);
Once again, tuples are workhorses of software design isomorphisms. objEq
is an 'object equivalent' consisting of closures; it's behaviour with data. You can now pass objEq
as an argument to another method, if that's what you need to do.
One common variation that I sometimes see is that instead of a tuple of functions, you can create a record of functions. This enables you to give each function a statically enforced name. In the theory of algebraic data types, tuples and records are both product types, so when looking at the shape of code, these are closely related. Records also enable you to preserve the name of each method, so that this mapping from object to record of functions becomes lossless.
The inverse mapping also exists. If you have a record of functions, you can refactor it to a class. You use the name of each record element as a method name, and the arguments and return types to further flesh out the methods.
As an example, consider this (over-)simplified Turtle class:
public class Turtle { public double X { get; private set; } public double Y { get; private set; } public double AngleInDegrees { get; private set; } public Turtle() { } public Turtle(double x, double y, double angleInDegrees) { this.X = x; this.Y = y; this.AngleInDegrees = angleInDegrees; } public void Turn(double angleInDegrees) { this.AngleInDegrees = (this.AngleInDegrees + angleInDegrees) % 360; } public void Move(double distance) { // Convert degrees to radians with 180.0 degrees = 1 pi radian var angleInRadians = this.AngleInDegrees * (Math.PI / 180); this.X = this.X + (distance * Math.Cos(angleInRadians)); this.Y = this.Y + (distance * Math.Sin(angleInRadians)); } }
In order to keep the example simple, the only operations offered by the Turtle
class is Turn
and Move
. With this simplified API, you can create a turtle
object and interact with it:
var turtle = new Turtle(); turtle.Move(2); turtle.Turn(90); turtle.Move(1);
This sequence of operations will leave turtle
as position (2, 1) and an angle of 90°.
Instead of modelling a turtle as an object, you can instead model it as a data structure and a set of (impure) functions:
public class TurtleData { private double x; private double y; private double angleInDegrees; public TurtleData() { } public TurtleData(double x, double y, double angleInDegrees) { this.x = x; this.y = y; this.angleInDegrees = angleInDegrees; } public static void Turn(TurtleData data, double angleInDegrees) { data.angleInDegrees = (data.angleInDegrees + angleInDegrees) % 360; } public static void Move(TurtleData data, double distance) { // Convert degrees to radians with 180.0 degrees = 1 pi radian var angleInRadians = data.angleInDegrees * (Math.PI / 180); data.x = data.x + (distance * Math.Cos(angleInRadians)); data.y = data.y + (distance * Math.Sin(angleInRadians)); } public static double GetX(TurtleData data) { return data.x; } public static double GetY(TurtleData data) { return data.y; } public static double GetAngleInDegrees(TurtleData data) { return data.angleInDegrees; } }
Notice that all five static methods take a TurtleData
value as their first argument, just as the above abstract description suggests. The implementations are almost identical; you simply replace this
with data
. If you're a C# developer, you may be wondering about the accessor functions GetX
, GetY
, and GetAngleInDegrees
. These are, however, the static equivalents to the Turtle
class X
, Y
, and AngleInDegrees
properties. Keep in mind that in C#, a property is nothing but syntactic sugar over one (or two) IL methods (e.g. get_X()
).
You can now create a pentuple (a five-tuple) of closures over those five static methods and a single TurtleData
object. While you can always do that from scratch, it's illuminating to transform a Turtle
into such a tuple, thereby illustrating how that morphism looks:
public Tuple<Action<double>, Action<double>, Func<double>, Func<double>, Func<double>> ToTuple() { var data = new TurtleData(this.X, this.Y, this.AngleInDegrees); Action<double> turn = angle => TurtleData.Turn(data, angle); Action<double> move = distance => TurtleData.Move(data, distance); Func<double> getX = () => TurtleData.GetX(data); Func<double> getY = () => TurtleData.GetY(data); Func<double> getAngle = () => TurtleData.GetAngleInDegrees(data); return Tuple.Create(turn, move, getX, getY, getAngle); }
This ToTuple
method is an instance method on Turtle
(I just held it back from the above code listing, in order to list it here instead). It creates a new TurtleData
object from its current state, and proceeds to close over it five times - each time delegating the closure implementation to the corresponding static method. Finally, it creates a pentuple of those five closures.
You can interact with the pentuple just like it was an object:
var turtle = new Turtle().ToTuple(); turtle.Item2(2); turtle.Item1(90); turtle.Item2(1);
The syntax is essentially the same as before, but clearly, this isn't as readable. You have to remember that Item2
contains the move
closure, Item1
the turn
closure, and so on. Still, since they are all delegates, you can call them as though they are methods.
I'm not trying to convince you that this sort of design is better, or even equivalent, in terms of readability. Clearly, it isn't - at least in C#. The point is, however, that from a perspective of structure, these two models are equivalent. Everything you can do with an object, you can also do with a tuple of closures.
So far, you've seen that you can translate a Turtle
into a tuple of closures, but in order to be an isomorphism, the reverse translation should also be possible.
One way to translate from TurtleData
to Turtle
is with this static method (i.e. function):
public static Turtle ToTurtle(TurtleData data) { return new Turtle(data.x, data.y, data.angleInDegrees); }
Another option for making the pentuple of closures look like an object is to extract an interface from the original Turtle
class:
public interface ITurtle { void Turn(double angleInDegrees); void Move(double distance); double X { get; } double Y { get; } double AngleInDegrees { get; } }
Not only can you let Turtle
implement this interface (public class Turtle : ITurtle
), but you can also define an Adapter:
public class TupleTurtle : ITurtle { private readonly Tuple<Action<double>, Action<double>, Func<double>, Func<double>, Func<double>> imp; public TupleTurtle( Tuple<Action<double>, Action<double>, Func<double>, Func<double>, Func<double>> imp) { this.imp = imp; } public void Turn(double angleInDegrees) { this.imp.Item1(angleInDegrees); } public void Move(double distance) { this.imp.Item2(distance); } public double X { get { return this.imp.Item3(); } } public double Y { get { return this.imp.Item4(); } } public double AngleInDegrees { get { return this.imp.Item5(); } } }
This class simply delegates all its behaviour to the implementing pentuple. It can be used like this with no loss of readability:
var turtle = new TupleTurtle(TurtleData.CreateDefault()); turtle.Move(2); turtle.Turn(90); turtle.Move(1);
This example utilises this creation function:
public static Tuple<Action<double>, Action<double>, Func<double>, Func<double>, Func<double>> CreateDefault() { var data = new TurtleData(); Action<double> turn = angle => TurtleData.Turn(data, angle); Action<double> move = distance => TurtleData.Move(data, distance); Func<double> getX = () => TurtleData.GetX(data); Func<double> getY = () => TurtleData.GetY(data); Func<double> getAngle = () => TurtleData.GetAngleInDegrees(data); return Tuple.Create(turn, move, getX, getY, getAngle); }
This function is almost identical to the above ToTuple
method, and those two could easily be refactored to a single method.
This example demonstrates how an object can also be viewed as a tuple of closures, and that translations exist both ways between those two views.
To be clear, I'm not trying to convince you that it'd be great if you wrote all of your C# or Java using tuples of closures; it most likely wouldn't be. The point is that a class is isomorphic to a tuple of functions.
From category theory, and particular its application to Haskell, we know quite a bit about the properties of certain functions. Once we start to look at objects as tuples of functions, we may be able to say something about the properties of objects, because category theory also has something to say about the properties of tuples (for example that a tuple of monoids is itself a monoid).

java.lang.Object com.vividsolutions.jts.index.quadtree.Quadtree
public class Quadtree
A Quadtree is a spatial index structure for efficient range querying
of items bounded by 2D rectangles.
Geometry
s can be indexed by using their
Envelope
s.
Any type of Object can also be indexed as
long as it has an extent that can be represented by an Envelope
.
This Quadtree index provides a primary filter for range rectangle queries. The various query methods return a list of all items which may intersect the query rectangle. Note that it may thus return items which do not in fact intersect the query rectangle. A secondary filter is required to test for actual intersection between the query rectangle and the envelope of each candidate item. The secondary filter may be performed explicitly, or it may be provided implicitly by subsequent operations executed on the items (for instance, if the index query is followed by computing a spatial predicate between the query geometry and tree items, the envelope intersection check is performed automatically.
This implementation does not require specifying the extent of the inserted items beforehand. It will automatically expand to accomodate any extent of dataset.
This data structure is also known as an MX-CIF quadtree following the terminology of Samet and others.

Preparation time
less than 30 mins
Cooking time
over 2 hours
Serves
Serves 10
Preheat the oven to 220C/430F/Gas 7.
For the stuffing, mix all of the stuffing ingredients together and chill in the fridge for 30 minutes.
For the pork, lay 3-4 pieces of kitchen string across a chopping board and then place the pork belly on top, skin side down. Spread the stuffing mixture all over the pork belly, season with salt and freshly ground black pepper, then place the pork tenderloin across the middle of the belly. Roll up the pork belly, then tie up, using the string, at equal intervals.
Rub a generous amount of sea salt into the skin of the pork belly and roast for 20 minutes in the oven, or until the skin is beginning to crisp up and turn golden-brown. Turn the oven down to 180C/360F/Gas 4 and roast for a further three hours. Remove from the oven and allow to rest for 10-15 minutes before carving.
Meanwhile, for the gravy, heat the olive oil in a large pan until smoking, then add the pork bones. Cook for 6-8 minutes, or until the bones are browned all over. Remove the bones from the pan and set aside.
Return the pan to the heat and fry the onion, carrot and celery for 4-5 minutes, or until golden-brown. Add the leeks and thyme and cook for a further 4-5 minutes, stirring continuously.
Add the white wine to the pan and cook for 6-8 minutes, or until the liquid has reduced by half in volume. Return the pork bones to the pan and add the chicken stock, bring to the boil then reduce the heat and simmer for two hours.
Pass the liquid through a sieve into a clean pan and discard the solids. Simmer the liquid for a further 30 minutes, or until thickened to a gravy consistency. Keep warm.
For the ratatouille, place all of the vegetables, except the tomatoes, tomato purée and basil, into a bowl and toss together with the olive oil. Season with salt and freshly ground black pepper, then transfer to a roasting tray. Cook in the oven, with the pork, for 10-12 minutes, or until the vegetables are beginning to colour.
Stir the tomatoes, tomato purée and basil into the vegetables, then continue to cook in the oven for 20 minutes, or until all of the vegetables are tender. Remove from the oven and cover with aluminium foil to keep warm. Keep the oven at 180C/360F/Gas 4.
For the roast potatoes, pour the olive oil into a large roasting tin and place in the oven until smoking.
Add the parboiled potatoes, rosemary and garlic to the pan and, using a large spoon, carefully toss the potatoes to ensure they get a good coating of oil. Season with salt and freshly ground black pepper, then roast in the oven for 40 minutes, or until golden-brown and crisp. Set aside.
For the glazed apples, lay the apple slices on a baking tray and sprinkle over the brown sugar. Using a mini blow torch, caramelise the sugar until melted and golden-brown, then allow to cool slightly. (If you don't own a blow torch, place the sugared apple slices under a hot grill until the sugar melts and turns golden-brown.)
To serve, spoon the roast potatoes and ratatouille onto serving plates. Thickly slice the stuffed pork and divide among the serving plates, then spoon some of the glazed apples alongside.

A short story about me
wake up, Neo!
I like to know how everything works on this simulation called “life”.
At my 6 years old, in a beautiful day on my class, i’ve found something strange under my desk. It was a CD-ROM of Animatrix film. I’ve searched for the owner, but i couldn’t find him, so i have take the CD to my home. I never heard about Matrix, but the CD had some information about the history, but in English.
-“how can i read this?”. I thought.
So i ran to my bedroom and looked for an English dictionary that i own from my mom, and translated the CD history, word by word, and at the end, i have discovered a new world, the world of the electron and the switch, the world out of that meets the eye.
Some years later, because of this CD, my computer won a new meaning: A door, that when it’s open to the world, can show all the humanity knowledge, from any time, from anywhere, about anything, like the Neo from Matrix, we can do everything in this world. But how it works? We can really enter anywhere? Read everything? How the computer works?
Since that, i keep myself searching, for unseen knowledge, locked doors, secret places, because that is my hobby, and The “Matrix” is my lab.

I'm just waiting for someone to suggest routine video-monitoring of all classrooms. Panopticon, here we come: "These kids are starting to use Photoshop mash-ups to make it look as if teachers are hitting kids and the like. False accusation of teachers abusing kids is already a big problem in schools as the authorities have to take these accusations seriously. But if kids can convincingly fake evidence too, the problem is compounded."


How to charge your electric BMW at a DC fast-charging station?
The next How-To video shows us how to create an optimal climate in any new BMW. The Climate Control system can be accessed via the …
by Adrian DorofteCurrently, there are two options for recharging your battery electric BMW: the AC stations which are more widespread and the DC stations which are more powerful. What you need to know about DC charging is right in the following video. First of all, the DC (direct current) charging stations are visibly larger than the alternative current (AC) ones. Secondly, their output is higher, typically 50 kW, as they are primarily intended to ensure a fast charging up to 80 percent of the battery level in a reduced amount of time.
On the regular AC stations, the charge speed of the BMW i3 is limited to 3.6 kW. To use DC stations, the electric vehicle must be equipped with the special, larger DC charging port. Before recharging, make sure you have correctly plugged in the charging cable. You must start the process by using the DC station display. A communication is established with the EV as to trigger the charging in a matter of seconds.
After reaching the 80 percent battery threshold for fast charging, the DC station point will continue to charge the battery in a normal mode as to not affect its lifetime. If anytime you would like to discontinue the process, you can do so by selecting the relevant STOP button from the display of the DC charging station.
The EV starring in this new BMW How-To video is the i3s model (I01 LCI), painted in Fluid Black with BMW i blue accents. The 20″ double-spoke alloy code 431 wheels further underline the sporty character of this BMW i3s.

I am not totally thrilled. Maybe my expectations of this book were too high, but it’s not my problem he wrote Cryptonomicon ;). Don’t take it wrong, I really like the book, but at over 900 pages, it is far too long and only the first installment of three books. Actually, it is three books, and it is volume I of the baroque cycle, which will have three volumes, each likely being 3 books again, bounding to become one. I already have volume II and make no mistake, I will read it.
<!– more –>
But I will just read it in steps and not try to read it in one go, and will not try to keep everything in my head. The thing is that the general story is good, the main characters are wonderful, the settings are interesting, but … there are far too many characters in general to even remotely come to grips with in a leisurely way and sometimes he goes too far in describing the surroundings or other things.

I am torn between thinking that he goes into too much detail in the book and that this level of detail is needed to go this deep into the story. Reflecting a bit on this I feel that the depth is needed indeed and he does well in doing that, but maybe I took it for too much of a leasurely book, which it really isn’t. The amount of characters would really have warranted a piece of paper where one could write down a short who’s who and who knows whom to be able to fall back on it from time to time. There were tables of the royal families of the times in there but they do not really help with all the non-noble, not-yet-noble, soon-to-be-noble, or maybe-noble people and to get them into perspective. On top of that they have too many different names and titles that keep changing and keep being added on.

Another thing that I don’t like is that while he says that it is a historical book, it is also a novel, so some things didn’t really happen as they did, meaning that you are often not sure if this is now really how things happened in history or of it isn’t. I mean he talks about Newton and other scientiest. He talks about different royals. So it’s a mixture of half-truths, that isn’t too wonderful. I likely have to do a further read into that before continuing with volume II. Somebody can gladly enlighten me as to how much is real in the book. Who really founded the MIT for example?

I can’t really give a final verdict yet, and I will likely have to get a different mind set for reading the next book. I will also take a pen and paper next to me to keep all the characters untangled. If I then can settle how much of the books is real and how much isn’t, then I will be a happy camper. For now, it’s merely a good book but this might change once I got through all the volumes.

Pharms - Escitalopram |
(daily) |
I'm afflicted with a generalized anxiety disorder, and depression.
I went off of Paxil after 9 years, dosed between 20 to 40 mg per day, after a few months, I started getting really agitated anxious and depressed. My doc suggested I try Lexapro because reports say it doesn't have the heavy sexual side effects of any of the older first generation antidepressants, and it's highly regarded in the anxiety disorder crowd.
I dosed at bedtime. The next day I felt better (relaxed), but oddly, everyone looked really unattractive and I began having weird thoughts about suicide. For me, suicidal ideation has not really ever occured before, and I'm 47 years old and have been in and out of therapy for over ten years.
I kept taking it for a few more days, but cut the dose to 5 mg. By the end of the week, I was really beginning to feel weirded out-like I was afraid to be on my own, afraid of my own thoughts and stuff.
By Saturday a.m., I felt compelled to go talk with my sister, and I had the oddest conversation about why people all shouldn't just end their own lives and stuff. I knew it wasn't me.
Anyway, to make a long story short, I stopped Lexapro for a week and was okay, except my anxiety came back, so I gave it another try and had basically had identical results-suicidal ideation.
I reported all this to my doctor and she told me to go back to Paxil, and after a few weeks I stabilized. But the suicidal ideations stopped within a couple of days after I stopped the Lexapro.
So, for me it wasn't a good med-it was a bad trip I don't want to go on again. And by the way, my experience was that Lexapro does have significant sexual side effects similar to all the other older ssri's.

Police involved in a Hot Pursuit will not make even the slightest attempts to preserve their own safety or welfare, or that of Innocent Bystanders. Whatever risky or insane driving the bad (or sometimes good) guy does, the cops will simply follow in his tire tracks, trying to imitate everything he does, no matter how much injury to themselves or damage to their car will result.
If the bad guy plows though a farmers' market, the cops will do the same to chase him.
If he jumps an open drawbridge, the cops will do it too (or at least try).
And if one cop wrecks the rest will mindlessly plow into him, sometimes without even making an attempt to avoid a wreck, 'cause the resulting pile of twisted metal is cool.
Sometimes this is done for humor, but most action movies/TV shows portray this as normal police behavior.
When police are the designated Mooks of a story, they are often also very bad drivers who will probably wreck just driving normally, which only adds to this trope.
Combining this and the fact they have guns makes them an easy stand in for the Redshirt Army in situations where the military isn't likely to be involved and possibly also Adults Are Useless if the protagonist is a kid.
In Video Games, this tends to get Turned Up to Eleven with cops intentionally trying to crash into the player at full speed and ignoring everything else.
Of course this is quite different from Real Life where police have training and procedures for pursuits. Watch any TV program on the subject and you will see the police are very careful, to the point of backing off and following by air if it looks like civilians will be harmed. Real Life cops will generally terminate (end) a pursuit when it becomes too fast or dangerous. Just as with other kinds of "unprofessional" behavior by the police, though, this trope may be relatively more justified in historical settings, since most police jurisdictions were less regulated and had much more freedom of action before about the 1970s or so.
Examples:
- In Full Metal Panic? Fumoffu, this is played for laughs when an obstinate police officer (who looks suspiciously like she wandered off the set of You're Under Arrest!) gives chase to Sousuke and Chidori double-riding a stolen bike using her squad car and fails epically. The next time we see her, she mentions she's on probation due to wrecking the car.
- In the Panty & Stocking with Garterbelt episode "Death Race 2010", Panty and Stocking chase after a ghost appropriately named "Speed Freak" through the city. Every last police officer in Daten City ends up chasing after it as well in their efforts to stop him. Thousands of police cars pile up into a mountain on top of him, but Speed Freak still easily tosses them aside.

- It happens quite a lot generally in the Lupin III franchise as a whole, but is taken up to 11 in The Fuma Conspiracy where the police chase our protagonists through a crowded market, across a river, over a rickety bridge and through a traditional Japanese bathhouse. The trope is somewhat subverted in that the police cars mostly survive the chase, but they still managed to cause a lot of property damage and mental scarring to the poor bathers.
- Sin City has wave after wave of cop cars getting wrecked or blasted by hookers in many stories that feature car chases. Leading a squad car into Old Town is the best way to avoid the cops.
- In the Werner story "Werner macht die Grünen blau", the two cops Bruno and Helmut, made punch drunk by Werner, try to chase him but end up driving on the wrong side of an Autobahn believing that everyone else is driving the wrong way.
- Buford T. Justice in Smokey and the Bandit.
- Parodied in The Blues Brothers (picture above), with an unbelievably large number of cops. Made funnier in that, since the heroes are driving an old police car, and the use of unnecessary violence in the apprehension of the Blues Brothers has been approved, the cops should be able to stop them, but they don't have the benefit of being on a Mission from God.
- The sequel was even worse, actually breaking the first film's world record for cars smashed. Check it out.
- Taxi 2. Dozens of police cars follow the main characters. Wherever the main characters' car goes, the police go as well — all of them. The damage caused by the followed car is nothing compared to the destruction caused by the cops. Eventually one cop wrecks and all of the others plow into him and into the resulting wreckage. Not one police car survives. Accompanied by a great sound track, as well.
- Batman Begins. Many cops engage Bruce Wayne's Tumbler in a high speed chase through highways and back streets as he's trying to save Rachel's life. Several spectacular crashes occur, with two or three car pileups, explosive caltrops being deployed, and the Tumbler even flattening another police cruiser. When Bruce gets back to the Batcave, Alfred (who has been following the news reports of the chase) tells him "It's a miracle no one was killed."
- Also, Batman Returns: Batman's coming up to a narrow alley, pursued by a few cop cars because the Batmobile was being controlled by the Penguin in an attempt to frame him. Batmobile jettisons stuff to become the Batmissile, which can squeeze through the alley. The cop cars... can't. Cue half a dozen cars all smashing into each other in a magnificent pile-up.
- Double subversion in the movie Short Time: the main character engages in this sort of behavior during a car chase... because he is actually suicidal. However he ends up miraculously surviving and gets a commendation!
- The SFPD cops who make the unwise decision to try to chase James Bond (who is driving a stolen fire engine) across the Third Street Bridge in A View to a Kill. The commanding officer makes the foolish mistake of stopping where his car gets crushed by the counterweight when the bridge is lowered.
- The cops and FBI agents in Eagle Eye stupidly follow the protagonist through cross traffic at red lights, smashing into innocent civilians along the way. One even tries to ram him head-on!
- Older than all of these are the Keystone Kops silent films. They all feature wild slapstick chases from a pack of rather silly policemen.
- Partially averted in The One, where the police SUVs backtrack to avoid oncoming traffic on a bridge, and call in a helicopter to help track the suspect. However, they still end up crashing at the end of the pursuit anyway.
- Used in The Matrix series to almost comedic effect, the Lemming Cops will always follow The Agents pursuing the heroes no matter what, being as reckless as The Agents are, causing much potential loss of human life as The Agents do, in their simple binary pursuit of the heroes, and becoming, as needed, the vessels that The Agents use to continue to chase the heroes down.
- Played for laughs in Beverly Hills Cop, as the police cars storming into the Big Bad's mansion to rescue the heroes get into a chain-reaction rear-end collision when a pair of Mooks crashes during an attempted getaway.
- In Unstoppable a bunch of cop cars make a tight turn to keep up with an out of control train, causing one of them to completely flip over in the process...even though there was absolutely no reason to pursue so recklessly (or at ALL), especially given that there was nothing they could do except hurt bystanders.
- The original Gone in 60 Seconds (1974), where the police were played by actual LAPD officers, has a scene where only one car was supposed to crash, but the rest of the cars crash anyway because they found it fun (plus H. B. Hallicki provided the cars, which he'd bought over the course of several years, so they didn't have to answer for smashed up cars), although one officer was almost crushed by the light can on the top of the car.
- The Vegas cops in Diamonds Are Forever not only crash into parked cars, walls, and each other as they pursue Bond, but they try to copy his Ramp Jump and Car Skiing with disastrous results.
- In the chase at the beginning of Striking Distance, the police continue to pursue a suspect even as their cars fall apart. Several end up over a hill.
- This trope is one of the basic comedic ingreditents of The Dukes of Hazzard. In almost every episode, the General Lee is chased by Sheriff Coltrane, and often also by one or more of his deputies in their cars. Despite the chases usually ending with one or more totalled police vehicles, Coltrane seems to enjoy the chase just as much as the Dukes.
- Lampshaded in an episode of Reno 911! in an interview with Deputy Travis Junior, he mentions an incident when he was chasing drug runner "Fast Eddie" McLintock with about 15 other cruisers. The lead cruiser wrecked and started a pileup. Deputy Junior mentions that he saw the wreck about a mile up, as he was the last in line, but he just floored it, because how often do you get to be in a 15 car pileup?
- Subverted in Blue Heelers when Jonesy pursues a suspect. When he is ordered to terminate the chase, he does (reluctantly), but does not acknowledge it to his superior, and when the suspect wraps his car around a tree Jonesy is very nearly brought up on disciplinary charges - the only thing that saves him is the discovery that the driver was probably on his mobile phone. Before he was chasing the suspect on a dirt road, when he couldn't see in the dust only to discover the suspect had stopped the (stolen, natch) car in the middle of the road, causing the police car to smash into it before flipping the bird and driving off.
- And subverted again in several episodes before that. The most notable example would probably be Brad, Susie's ex husband, who became a paraplegic after a pursuit ended in a crash. He blames himself for what happened but listening to Brad and the pursuit controller he was at least as in control and unlemming-like as most examples on this list, his only possible fault in hesitating to follow the order to terminate when he reports the suspect going 140 KPH (about 85 MPH) on a bad road.
- Happens in the MacGyver (1985) episode "The Thief of Budapest". A lot of police cars get totalled as a result.
- JAG: In "Dangerous Game", a Virginia deputy sheriff pursues a speeding car with civilian dressed Navy Seals and accidentally gets himself killed. The Navy Seal who drove the other car stands trial for negligent homicide. While this is obviously not played for fun, the writers were genre-savvy enough to have the sheriff back at the station watching Smokeyandthe Bandit.
- Happens in first episode of season 2 of Stranger Things, in which a police chase of some bank robbers ends with Kali using her powers to make one of the officers imagine a tunnel ceiling collapsing in front of him, causing him to slam on the brakes, and then the two squad cars behind him to collide with him. Meanwhile, Kali's crew gets away unscathed.
- The Kill Point: During the initial robbery, an off-duty FBI agent who happened to be present in the bank's lobby at that moment, pursues the robbers and immediately starts a gunfight outside the building. A single person against five heavily armed suspects with only her sidearm for back-up. She's lucky a security guard just happened to circle back to back her up, or all she would have accomplished is getting herself and/or innocent bystanders killed. They fall back into the building and turn the whole thing into a protracted hostage situation instead, and she later dies from her injuries in the hospital anyway.
- Cops in the Grand Theft Auto series are completely reckless in their pursuit of the player — they'll follow you off cliffs, into water, and plow through traffic, often causing explosive pile-ups. Sometimes the player's "Wanted" level will increase because so many cops have killed themselves in the chase. It gets even more ridiculous when, in Vice City, you turn on the cheat where going fast enough causes cars to fly.
- Sometimes the cops in GTA4 take the "lemming" part a little too literally...
- Even on foot it goes sideways as many GTA police simply cannot swim.
- In Grand Theft Auto: Chinatown Wars, besides escaping into a safehouse, the main/only way to get your wanted level to zero is to force the cops tailing you to crash, one at a time. While incredibly fun, this isn't the smartest mechanic, as it only counts when an occupied cop car crashes. Hitting an unoccupied one or killing a pedestrian officer will actually increase your wanted level.
- The same also seems to, very ironically, apply to paramedics too - the ambulances seem to exhibit much the same behaviour as the cop cars, causing more fatalities than they prevent: it's very common for them to run over half a dozen people in their attempt to reach a single wounded person, then run over a few more after they're done.
- Half-Life 2: Metrocops/Civil Protection officers. Unlike the Combine Overwatch Soldiers, they don't really have a good grasp of tactics; cops will regularly charge toward you disregarding cover or environmental hazards, and they do so in large groups. Practically the only thing they care to avoid is thrown grenades. This can lead to some amusing moments early on in the game- particularly, during a segment of Route Kanal, a train comes down the tracks a squad of Metrocops happens to be rushing toward you on...
- Need for Speed: Most Wanted: Crashing into one of the marked buildings or roadside objects during pursuit will cause it to crush down on the police cars chasing you.
- The cops are a lot stupider than just running into obstacles which they almost always can't avoid due to going too fast. They'll gladly run into their own roadblocks, sometimes opening a hole for the player they otherwise couldn't have achieved, and they will happily go zooming over the same jumps the player can, destroying their car in the process. Indeed, it sometimes makes the radio chatter feel full of Narm since they sound so much more intelligent on the radio than they actually act.
 You can steer the cop car into oncoming traffic.
- Played around in the Hot Pursuit series. The AI-controlled basic police are not any smarter, but the interceptor units, human or AI, are competent enough to be able to stop the racers.
- When the cops are after you in Driver, they seek to chase and ram you no matter at what costs, up to kamikaze-like head-on collisions when both you and the cops are driving at maximum speed. This is justified by the fact that nobody can get out of their car, and the squad cars are actually the police's only weapon against you. In the sequels, the cops are smarter, but still not smart enough not to chase you over ramps.

- Scarface: The World Is Yours. One essential missions involves a high speed chase with the cops flying off a high ledge to crash into the debris below and die horribly. Their 'crime'? Stealing donuts. So ... yeah.
- Just Cause 2 gives us the notoriously thick Panauan military/police force. When on Rico's tail, they'll do anything to take him down, including crashing into each other and exploding, plunging off cliffs, blithely ignoring their burning vehicle that's due to explode in seconds, and sending streams of weak jeeps and motorcycles to challenge an armored vehicle.
- Cops in the Saints Row franchise are particularly dense, though they are mostly good about not plowing into cops on foot.
- Parodied in Family Guy when Stewie, Brian and Mort are in a submarine, being chased by another submarine. They manage to make their pursuer crash and the moment it does so, about two dozen police cars come in apparently from nowhere, crashing into the sub.
- In an episode of The Simpsons Marge and her friend Laura Powers are being chased by the police across the desert. Homer, riding in Chief Wiggum's car (long story) successfully warns them that they're about to drive into The Grand Chasm and they brake to a stop in time, while Wiggum and Homer go hurtling past them and over the edge, but are both fine because they land in a giant heap of garbage on the bottom of the Chasm.
- South Park:
- In one episode, Cartman and Kyle are riding their Big Wheels to California. A CHP Cruiser spots them and gives chase, at what could be no faster than 5mph. Despite this, the police car somehow manages to lose control and flip over the median.
- In another, Kenny and Cartman get into an extremely slow version of the O.J. Simpson police chase in a battery-powered toy car. When it runs out of juice it slows to a halt, then a second later, a dozen police cars come roaring in from off-screen to have a fiery pile-up.
- The Bikini Bottom police are prone to this type of pursuit, notably when chasing Spongebob Squarepants and Mrs. Puff during the former's driving test. There is a tanker truck of fruit punch for seniors involved.
- Teen Titans Go!: In "Driver's Ed", a a trail of police cars chase Robin into a supermarket, where they pile-up.

"You approach the eyes carefully. They seem to alight with laughter, then quickly disappear into the shadows. A red door fades into existence, the doorknob a golden jewel beckoning with a soft, bluish glow. Do you open the door? YES or NO"
YES
NO
