Multipath occurs
in just about every terrestrial radio link, especially if the receiver is at
a location that is non-line of sight of the transmitter. Multipath is caused
by the transmitted signal arriving at the receiver via multiple paths. The
transmitted signal reflects off objects in the environment. These signals
arrive at the receiver some time after the initial direct signal as they
travel a longer distance and so have a longer propagation time. This results
in a spread of the signal in time, which is referred to as delay spread.

Login/Group Role Dialog¶
Use the Login/Group Role dialog to define a role. A role may be an individual user (with or without login privileges) or a group of users. Note that roles defined at the cluster level are shared by all databases in the cluster.
The Login/Group Role dialog organizes the creation and management of roles through the following dialog tabs: General, Definition, Privileges, Parameters, and Security. The SQL tab displays the SQL code generated by dialog selections.
Use the fields on the General tab to identify the role.
Use the Name field to provide the name of the role. The name will be displayed in the tree control.
Provide a note about the role in the Comments field.
Click the Definition tab to continue.
Use the Definition tab to set a password and configure connection rules:
Provide a password that will be associated with the role in the Password field.
Provide an expiration date for the password in the Account Expires field (the role does not expire). The expiration date is not enforced when a user logs in with a non-password-based authentication method.
If the role is a login role, specify how many concurrent connections the role can make in the Connection Limit field. The default value (-1) allows unlimited connections.
Click the Privileges tab to continue.
Use the Privileges tab to grant privileges to the role.
Move the Can login? switch to the Yes position if the role has login privileges. The default value is No.
Move the Superuser switch to the Yes position if the role is a superuser within the database. The default value is No.
Move the Create roles? switch to the Yes position to specify whether a role is permitted to create roles. A role with this privilege can alter and drop roles. The default value is No.
Move the Create databases switch to the Yes position to control whether a role can create databases. The default value is No.
The Update catalog? switch is disabled until the role is given superuser privileges. Move the Update catalogs? switch to the No position to control whether a role can update catalogs. The default value is Yes when the Superuser switch is in the Yes position.
Move the Inherit rights from the parent roles? switch to the No position if a role does not inherit privileges. The default value is Yes.
Move the Can initiate streaming replication and backups? switch to the Yes position to control whether a role can initiate streaming replication or put the system in and out of backup mode. The default value is No.
Specify members of the role in the Role Membership field. Click inside the Roles field to select role names from a drop down list. Confirm each selection by checking the checkbox to the right of the role name; delete a selection by clicking the x to the left of the role name. Membership conveys the privileges granted to the specified role to each of its members.
Click the Parameters tab to continue.
Use the fields on the Parameters tab to set session defaults for a selected configuration parameter when the role is connected to a specified database. This tab invokes the ALTER ROLE… SET configuration_parameter syntax. Click the Add icon (+) to assign a value for a parameter.
Use the drop-down listbox in the Name field to select a parameter.
Use the Value field to specify a value for the parameter.
Use the drop-down listbox in the Database field to select a database.
Click the Add icon (+) to specify each additional parameter; to discard a parameter, click the trash icon to the left of the row and confirm the deletion in the Delete Row popup.
Click the Security tab to continue.
Use the Security tab to define security labels applied to the role. Click the Add icon (+) to add each security label selection.
Specify a security label provider in the Provider field. The named provider must be loaded and must consent to the proposed labeling operation.
Specify a a security label in the Security Label field. The meaning of a given label is at the discretion of the label provider. PostgreSQL places no restrictions on whether or how a label provider must interpret security labels; it merely provides a mechanism for storing them.
To discard a security label, click the trash icon to the left of the row and confirm the deletion in the Delete Row popup.
Click the SQL tab to continue.
Your entries in the Login/Group Role dialog generate a SQL command (see an example below). Use the SQL tab for review; revisit or switch tabs to make any changes to the SQL command.
Example¶
The following is an example of the sql command generated by user selections in the Login/Group Role dialog:
The example creates a login role named alice with pem_user privileges; the role can make unlimited connections to the server at any given time.
Click the Info button (i) to access online SQL help.
Click the Help button (?) to access the documentation for the dialog.
Click the Save button to save work.
Click the Cancel button to exit without saving work.
Click the Reset button to restore configuration parameters.

I love computers and video games since I was a kid. My first console was a Nintendo DSi, I used to play Pokemon in it, I had spent hours playing Pokemon, which is one of my favorite games. I have played many games throughout my life, but, unfortunately, in my country, the taxes and fees are high, because of that consoles, games, and computers are expensive here, but I still love them, even do not have money enough to buy them. Nowadays, I used to play League of Legends.
I have found out about this new hobby during the lockdown, the first Programming language that I have seen was JavaScript. Since then I watch many videos about it and make simple programs. I started to attend CS50x lectures in January, I have learned new things about Compute Science, this course has changed my life and made me meet new people from other countries through cs50's Discord Server. Sometimes It was hard to solve the psets, but now I am sure that everything was worth it.
I love Animes (Japanese cartoons), I have been watched more than 100 animes (Maybe I'm addicted to it). My favorites genres are drama and romance, but I also like action and comedy. My favorites animes are Kimi no Wa (Your Name) and Shigatsu wa Kimi no Uso (Your Lie in April).
I listen to music to spend time when I am bored. I am not sure which is my favorite genre or my favorite song. All that is in my playlist are very good. Click beneath to take a look at my playlists.

Flexibility is the ability to move muscles and joints through their full ranges of motion (ROM). Stretching refers to the process of elongating connective tissues, muscles and other tissues. Flexibility and stretching exercises fall into several categories depending on the manner in which the muscle is stretched.
- Static stretching - this involves stretching to the fartherest point of muscle elongation and holding the stretch. This method is the safest and has been proven as a means of enhancing flexibility. These stretches are easy to learn, easy to execute and requires little energy expenditure. Disadvantages of this method is that the exercises lack specificity and do little to enhance co-ordination.
- Dynamic and ballistic stretching - Ballistic stretching involves bobbing, bouncing, rebounding and rhythmic types of movement. Momentum is the driving force that moves the body or limb to forcibly increase the ROM. This technique is the most conroversial because it can cause the most soreness and injury as it fails to provide adequate time for the tissues to adapt to the stretch.
For this reason dynamic stretching is often incorporated into training programs. Dynamic stretching does not end with bouncing or jerky movements. Instead, all movements are controlled and thus enhance optimal dynamic flexibility, essential for all sports.
- Passive stretching - with this technique you are relaxed and need to make no contribution to the ROM. An external force is created by a manual or mechanical outside agent. This technique is most suitable when antagonist muscles restrict flexibility. But, there is a great risk of soreness and injury if a partner applies the external force incorrectly.
- Active stretching - This is accomplished by using your own muscles without the application of any external force e.g. standing upright and slowly lifting one leg as high as possible. Active stretching is preferred when the weakness of the muscles producing the movement (agonists) restrict flexibility. This form of exercise is essential to the athlete because it promotes dynamic flexibility and is the most specific to a given discipline. These stretches are easier to work into a routine as they do not require equipment or a partner.
Incorporating a stretching program into your workout
Begin with a general warm-up. This can consist of movements not directly related to the activity itself i.e. joint rotations, gentle twisting & bending, brisk walking, jogging or rope-skipping. Here the goal is to increase muscle blood-flow, increase your rate of respiration and volume of oxygen intake and to raise your core body temperature.
General recommendations (duration, frequency and intensity will depend on your level of flexibility) for a healthy individual...
- Perform two to three repetitions of each stretch for a duration of 10 seconds; or one repetition of each stretch for 30 seconds.
- As training progresses, increases the number of successive repetitions and gradually increase your range of motion.
- As a general rule, non-athletes should stretch at least once a day, three to five days per week to maintain flexibility (more if your want to improve). Depending on the sport, dedicated and serious athletes may require two to three stretching sessions per day for 6 to 7 days per week.
- Within a workout session, gently stretch after a light warm-up, keeping your main stretching session for after the main part of your workout. At this stage your tissue temperatures are highest, making stretching both safer and more productive.
- Stretch intensity is decided by the athlete. In general, stretch to the point of tension, not pain.

|
Anterior ankle and instep
- Kneel with your shins and instep elevated by a folded towel and your toes pointing backwards.
 The later position is called 'W sitting' and is bad for the knees. Do not do this stretch if you have knee problems. |
|
Achilles tendon and posterior lower leg
- Lean forward against a wall with one leg bent and the other leg straight with the heel raised.
- Exhale, bend your arms, lean towards the wall, and slowly shift your weight forward while attempting to press your rear heel to the floor.
|
This stretch also effectively stretches the tissues behind the knee. |
|
Hamstrings
- Sit on the floor with one leg straight and the other bent at the knee with the heel touching the inside of the opposite thigh.
- Lower the outside of the thigh and calf of the bent leg onto the floor.

- Grasp your feet or ankles and pull them as close to your groin as possible.
- Exhale and lean forward from the hips. Keep your back straight and attempt to lower your chest to the floor.
|
If you have tight adductors, you may find it easier to perform this stretch with your heels extended slightly forward. |
|
Quadriceps
- Kneel with your knees together, buttocks on the floor, heels by the sides of your thighs, and toes pointing backwards.
- Exhale and lean backward without letting your feet flare out to the sides.
|
Do not arch your back. Instead, contract your gluteals and rotate your pelvis backward. Do not allow your knees to rise off the floor or spread apart. |
|
Hips and gluteals
- Sit on the floor and flex your left knee so that your left foot points to your right.
- Cross your right leg over your left leg and place your right floot flat on the floor.

- Place your palms on the floor by your hips with your fingers pointing forward.
- Exhale, press down on the floor, raise your head and trunk, and arch your back while contracting the gluteals to prevent excessive compression of your lower back.
|
|
Upper back
- Kneel on all fours, extend your arms forward, and lower your chest to the floor.
- Exhale, extend your shoulders, and press on the floor with your arms to arch your back.
|
|
Posterior neck
- Stand of sit and interlock your hands behind your head near the crown.
 Keep your shoulders depressed during this stretch.

selectedList
ParameterThe selectedList parameter is a boolean/numeric value denoting whether or not to display the checked opens in a list, and how many. A number greater than 0 denotes the maximum number of list items to display before switching over to the selectedText parameter.
$("select").multiselect({ selectedList: 4 // 0-based index });
selectedText
Passing a function to the selectedText
option gives you low-level control of what the widget displays. The function receives three arguments:
the number of checkboxes checked, the total number of checkboxes, and an array of the checkboxes (DOM elements) that were checked. Example usage:
$("select").multiselect({ selectedText: function(numChecked, numTotal, checkedItems){ return numChecked + ' of ' + numTotal + ' checked'; } });
The selectedList
option is simply a convenience method for the selectedText
option.

The above examples demonstrate how the ability to pass functions as arguments significantly enhances the expressive power of our programming language. We can achieve even more expressive power by creating functions whose returned values are themselves functions.
We can illustrate this idea by looking again at the fixed-point example described at the end of section \ref{sec:proc-general-methods}. We formulated a new version of the square-root function as a fixed-point search, starting with the observation that $\sqrt{x}$ is a fixed-point of the function $y\mapsto x/y$. Then we used average damping to make the approximations converge. Average damping is a useful general technique in itself. Namely, given a function $f$, we consider the function whose value at $x$ is equal to the average of $x$ and $f(x)$.
We can express the idea of average damping by means of the following function:
average(x, f(x)); } \end{JavaScriptClickable} \end{lrbox} \href{https://sourceacademy.nus.edu.sg/playground#chap=1&prgrm=GYVwdgxgLglg9mABAQwG4FMBOyDm6AUAHgDQCeAlIgN4BQi9im6UImSRiA1IhYgPSIATAG4aAXxqhIsBCgzY8AfQAmyALYAHfMEq0GjZqySFEAXgB8crLgIlEwIuXKiJNNNaWrN+AM4BHEGQmcnwARgAGZyA}{\usebox\lstbox}
The function average_damp is a function that takes as its argument a function f and returns as its value a function (produced by the function definition expression) that, when applied to a number x, produces the average of x and f(x). For example, applying average_damp to the square function produces a function whose value at some number $x$ is the average of $x$ and $x^2$.

Notice how this formulation makes explicit the three ideas in the method: fixed-point search, average damping, and the function $y\mapsto x/y$. It is instructive to compare this formulation of the square-root method with the original version given in section \ref{sec:sqrt}. Bear in mind that these functions express the same process, and notice how much clearer the idea becomes when we express the process in terms of these abstractions. In general, there are many ways to formulate a process as a function. Experienced programmers know how to choose process formulations that are particularly perspicuous, and where useful elements of the process are exposed as separate entities that can be reused in other applications. As a simple example of reuse, notice that the cube root of $x$ is a fixed point of the function $y\mapsto x/y^2$, so we can immediately generalize our square-root function to one that extracts cube roots:[2]
x / square(y)), 1.0); } \end{JavaScriptClickable} \end{lrbox} \href{https://sourceacademy.nus.edu.sg/playground#chap=1&prgrm=GYVwdgxgLglg9mABAQwG4FMBOyDm6D6AJsgLYAOAFMAJSIDeAUIs4pulCJkgB6IC8APhQZseCtwA0iYOOrUA3AwC+DUJFgJhWXOnESAnrUYtW7TknGIA1IkOIA9IgBMilRAQBnKIihwANtqQ6PyIAAwAdKFRoQCMimrQ8EjAMNzohPhkcDBgUFRSKZhe+Dgg6B4eRkwsCRpIEH5wHgToYHAgOAAWerZVJiZsHFwoAEYelgC0vYgAPD7+gRDoiiYqJrVJPpj6+ADuMFDdpeWV9NX9iO5gXohg6NzefNIUxxUK5-2D5peNzfit7S6LzKFSkdwe1A+F36AH5bvcoFDoSwAFxbHb7Q4UcFQd6rD5fYZQbZ7A7dQrFV6VVyqcCJTTIMayM4DMzDXgCJ6hRBw3hoibcGkbTQeACOIGQbGZxhYhJ4iAAVIhBcpaepNhAQCMCJg4HA8tw+rK2clUulMtlchQ0No8ERSJR9PwhLxHGKJVLDNQJEjkX6YpF3ioGJrtfhdfqKE4AOwKIA}{\usebox\lstbox}
When we first introduced the square-root function, in section \ref{sec:sqrt}, we mentioned that this was a special case of Newton's method. If $x\mapsto g(x)$ is a differentiable function, then a solution of the equation $g(x)=0$ is a fixed point of the function $x\mapsto f(x)$ where \[ f(x) = x - \frac{g(x)}{Dg(x)} \] and $Dg(x)$ is the derivative of $g$ evaluated at $x$. Newton's method is the use of the fixed-point method we saw above to approximate a solution of the equation by finding a fixed point of the function $f$.[3] For many functions $g$ and for sufficiently good initial guesses for $x$, Newton's method converges very rapidly to a solution of $g(x)=0$.[4]
In order to implement Newton's method as a
function, we must first
express the idea of derivative. Note that derivative,
like
average damping, is something that transforms a function into another
function. For instance, the derivative of the function $x\mapsto
x^3$ is the function $x \mapsto 3x^2$. In general, if $g$ is a
function and $dx$ is a small number, then the derivative $Dg$ of $g$ is
the function whose value at any number $x$ is given (in the limit of
small $dx$) by
\[Dg(x) = \frac {g(x+dx) - g(x)}{dx} \]
Thus, we can express the idea of derivative (taking $dx$ to be, say,
0.00001) as the
function
(g(x + dx) - g(x)) / dx; } \end{JavaScriptClickable} \end{lrbox} \href{https://sourceacademy.nus.edu.sg/playground#chap=1&prgrm=GYVwdgxgLglg9mABAEwKYCcYDcAUBzASkQG8AoRCxdVKEdJAD0QF4A+RfHJgahQaIC0iPFwJEA9HwDcpAL6lSoSLASIIIAEapRJKjTqNEAKkRMTDKYnmk0mXOq0EcAVgJSgA}{\usebox\lstbox}
Like average_damp, deriv is a function that takes a function as argument and returns a function as value. For example, to approximate the derivative of $x \mapsto x^3$ at 5 (whose exact value is 75) we can evaluate
With the aid of deriv, we can express Newton's method as a fixed-point process:
x - g(x) / deriv(g)(x); } function newtons_method(g, guess) { return fixed_point(newton_transform(g), guess); } \end{JavaScriptClickable} \end{lrbox} \href{https://sourceacademy.nus.edu.sg/playground#chap=1&prgrm=MYewdgzgLgBFIBsCmAnAhmYSYF4YAYA6fE-ARgG4AoAMwFdMoBLcGGpgDyQBMB9ABxBMwUABQ0ANGyYpovAOZ0kECAEoYAbyowdbBsGatgCEBCS8kYEHXkALURykBPdVt3uYKJFDoowMNAAjCAcYAFoYFxgAHjhEVAwsancAX21dekYWfygUJ14AdyYoe0VlNU10jxhQSFgwJA5YPBpRMpVVZOrPb19-Y1NzS2s7NqUVKQam1SrujwB+GCmoWbndAC44PMLi+2XO2bT3Lx8-LfyikvEZOXa1ajTMg2yA4IdXWZO+mA4YAD48PgYItfpswhwHlRatAYNxfoDiKRKLR9IZ-NxUEwAG5tD7HXpneF-GBtUIAalhHHUEXk73UAHpKZCnmilkgCvAwLxchgIDQQCgALa4yq6L6E3DE34094wRkYlDY3HvZmol4NDngCC8QXeWwgbhtKR3PE6cX+dhcPiCYRiDWc7noSD8oW443je5UNJUCAARxQYgAbJ0gA}{\usebox\lstbox}
The newton_transform function expresses the formula at the beginning of this section, and newtons_method is readily defined in terms of this. It takes as arguments a function that computes the function for which we want to find a zero, together with an initial guess. For instance, to find the square root of $x$, we can use Newton's method to find a zero of the function $y\mapsto y^2-x$ starting with an initial guess of 1.[5] This provides yet another form of the square-root function:
square(y) - x, 1.0); } \end{JavaScriptClickable} \end{lrbox} \href{https://sourceacademy.nus.edu.sg/playground#chap=1&prgrm=GYVwdgxgLglg9mABGApgdygg+lATgQzAGdg5cBbACgHMBKRAbwChFXcUoRckAPRAXgB8iPgFpE1Sj3oB6RABMUuGADcatKbQDcTAL5NQkWAmTpMxLOQ4ALOPJoAaCSBREi9Zq0TtO3RMBgeFHksAAc4GDAoSlQMbDxCEjIqOidqFzdtPSYIBCIoREwAGyVCCBQBRAAGADoq+qqARh1DaHgkAKCQ8Mjo4CcA3HysdNd3RhYvVuMkCCK4IhQsFDA4EGprKScATw9Jry8fLiR8ACMiKURxXcQAHkK4EoJIFB0D-QPp9sLcbaw0GBQTajTITA4HXLEAqoHgFfj+GgZdxvcFsDjHRBzBZLFZrDaIsZOGFQWj7VGogD8plhZPJBwAXD8-gCgTEULCsu8yUc-HhmYDNoNhiDkdkviYzhdpGDDui-HxBPCqogqXxGaIeDp9JD8go+Eq6g1mgZwG0TIplGo6DK0b5eAJhDRLgBqPX0cSSaSyPVak1Gb5EACOIHw7E0Nu8cvtACoRL7xUgg7hotLPLK7aY4hYrEC7JRtg7EEGQ2GbuIeA5aXTqwdGnUsvomEnogA2bRAA}{\usebox\lstbox}
We've seen two ways to express the square-root computation as an instance of a more general method, once as a fixed-point search and once using Newton's method. Since Newton's method was itself expressed as a fixed-point process, we actually saw two ways to compute square roots as fixed points. Each method begins with a function and finds a fixed point of some transformation of the function. We can express this general idea itself as a function:
This very general function takes as its arguments a function g that computes some function, a function that transforms g, and an initial guess. The returned result is a fixed point of the transformed function.
Using this abstraction, we can recast the first square-root computation from this section (where we look for a fixed point of the average-damped version of $y \mapsto x/y$) as an instance of this general method:
x / y, average_damp, 1.0); } \end{JavaScriptClickable} \end{lrbox} \href{https://sourceacademy.nus.edu.sg/playground#chap=1&prgrm=GYVwdgxgLglg9mABMGAPApgEwPoAc4xhTZzDZQBOAhmAM7BwUC2AFAOYA0ilN9jTXNiHS1aASkQBvAFCI5iCuiggKSFBhz5CUFjzoNm7MYOGixAbmkBfaRAS0o3OABt01SOkQBeRAAYAdL5BvgCMlqCQsAjIaFh4BEQswFwoFA7YQiLiUrLyEdDwSBDOcLTo2OhgcCBsABYsqFwAnhIy8u0KSipIVABGtA2IALSILYgAPE6u7hDolu027flRSJRN2ADuMFD1mWY5HfJ2dI5g6KiOPsDspuLzh53KqojFpeWV1XU3WVxnF2K5B6HAD8iD+UEBQPaAC5uBR1lsdixwRZIYt5Ionqt4ZttvVUuk9ndrNJloVEH0BqhWpDMd1EKhEAA+Hy+RCgxmwoaoSw2MnRKgANzcVDY5UwVCYuCSNPadOejK8TIpwuoYoaKQaYlRfPABQFqtF6A1YzaGK6z0GAGpRhIAPSIABMvNJepWiFoAEcKDpqQdzViYhp4toSGQ9HxDJCoXImt5lYyHU0ONGY0KRWLsBKpSmYx0QoEddJpF6fSwAGwWIA}{\usebox\lstbox}

We began section \ref{sec:higher-order-procedures} with the observation that compound functions are a crucial abstraction mechanism, because they permit us to express general methods of computing as explicit elements in our programming language. Now we've seen how higher-order functions permit us to manipulate these general methods to create further abstractions.
As programmers, we should be alert to opportunities to identify the underlying abstractions in our programs and to build upon them and generalize them to create more powerful abstractions. This is not to say that one should always write programs in the most abstract way possible; expert programmers know how to choose the level of abstraction appropriate to their task. But it is important to be able to think in terms of these abstractions, so that we can be ready to apply them in new contexts. The significance of higher-order functions is that they enable us to represent these abstractions explicitly as elements in our programming language, so that they can be handled just like other computational elements.
In general, programming languages impose restrictions on the ways in
which computational elements can be manipulated. Elements with the
fewest restrictions are said to have
first-class status. Some
of the rights and privileges
of first-class
elements are:[6]
JavaScript, unlike other common programming languages, awards functions full first-class status. This poses challenges for efficient implementation, but the resulting gain in expressive power is enormous.[8]

BED OF ROSES A film review by Steve Rhodes Copyright 1996 Steve Rhodes
RATING (0 TO ****): ** 1/2
BED OF ROSES is a wonderful fairy tale of a movie, at least the first two thirds of the movie is, which is the movie's major, but not quite fatal flaw. It is not that the last third of the movie is bad, it just does not exist at all! It is a movie that promises much more than it delivers, and yet it is a touching and romantic fable that lifts your heart before it makes a fast exit for reasons that baffle me. I am glad I saw it, but I wish I could have gotten to know the two lead characters much more. I really care about these two sweet souls.
Playing a character similar to the wonderful one he played in the much better movie UNTAMED HEART, Christian Slater is Lewis Farrell.  One day he delivers flowers from an anonymous giver to Lisa Walker (Mary Stuart Masterson).
Lisa is a successful but sad and young new VP at a Manhattan company. She has a mysterious and troubled childhood which has prevented her from ever falling in love. Her "boyfriend" Danny (Josh Brolin) is just that, a friend. They are intimate, but she does not care for him much; he is just a convenience. They are both workaholics who sometimes fit each other into their busy schedules.
When Lisa gets her flowers, she becomes obsessed with finding out who sent them. Although Lisa is upset by all of this, her best friend Kim (Pamela Segall) loves it and tells her, "with a fantasy like this who wants the truth?" Kim tells Lisa her opinion of her current boyfriend Danny, "He's the romantic equivalent of a night-light."
In the straightforward but poetic script by writer and director Michael Goldenberg, Lisa quickly finds out that, you guessed it, Lewis sent the flowers. He invites her to spent the day with him. The day turns out perfect which scares her. Lewis tells her not to worry since "every now and then everybody is entitled to too much perfection." Shaken, Lisa tells Kim that night that "I don't have room in my life for somebody this great. I work for a living."
Lisa's fears intensify as Lewis corners the market for roses in The Big Apple and sends them all to her apartment. He lost his first wife during pregnancy, and he lives in mortal fear that he will lose Lisa as well, hence the romantic overkill.
Just when you get thoroughly hooked on this movie, it takes a sharp turn left followed a couple of minute later by a sharp right and then a few minutes later it abruptly ends. I could not figure out if the writer ran out of ideas or what. Perhaps test screening audiences did not like the last part so the editor (Jane Kurson) just cut it entirely. For whatever reason, the producers (Michael Haley, Allan Mindel, and Denise Shaw) should have demanded the script be finished properly before they released the film. This is an enthralling film transformed into a mediocre one because of this truncation. I suspect the cause is the editing because there were other parts, like her abused childhood, that are hinted at somewhat obliquely and where you are keep waiting for more explanations or flashbacks that never materialize. I think they exist on some cutting room floor. The movie feels more like a great work in progress than a completed film. Perhaps not on the level of Mahler's tenth, but at least something special that I wish had been fully developed.
The acting by Masterson and Slater is marvelous. She delivers a compelling and complex performance. Slater gives a genuinely tender and touching one. In one of many good scenes he takes her to listen to children's stories at the library not because he has kids but because the storyteller is so good. The chemistry between them where he loves her, but she is scared to love him is quite believable. Pamela Segall takes the minor role as the friend and makes it special. I liked the makeup where they had Kim look much prettier than Lisa making the audience wonder whether Lewis would fall for Kim at some point in the show, and if so when.
The sets (Stephen McCabe), especially of Lewis's parents at their large Normal Rockwell style house at Christmas, give a warm and peaceful ambiance. The cinematography (Adam Kimmel), particularly in the use of lights and shadows, cast a melancholic overlay on top of an outwardly happy show thus mirroring the trouble in Lisa's inner self.
BED OF ROSES runs way too short at just 1:27. It is rated PG for a couple of bad words. This romance would not offend anyone of any age. There is no sex, nudity, or violence of any kind. There are a few quite effective but simple kisses. Nevertheless, this is one very romantic movie. Okay, two thirds of a romantic movie. The movie is strong enough that even though they amputated it, I still recommend it, but I am unable to give it more than ** 1/2 because of this travesty.
**** = One of the top few films of this or any year. A must see film. *** = Excellent show. Look for it. ** = Average movie. Kind of enjoyable. * = Poor show.  Totally unbearable.

The purpose of this library is allow developers to create components (data lists in particular) not by implementing them with html, styles and code but by describing (defining) them. Then it is concern of the UX library to generate these components, this way we effectively separate core (business) logic of the application from the UI implementation.
With help of this library you define (describe) the data list representation with following features
The major benefits from using this library could achieve large data driven applications with a lot of tables and lists. Using this library you could easily and reliable describe desired table representations without concern how these data will be rendered. Library provides strict set of API (aka description DSL) to render UI components, this allows large teams to stay sync on how to create and use data lists inside application, no need to copy / paste html css code when create new components or invent some base classes which abstracts common list implementation for the application.


{{ template "header-grpc.html" . }}
Note: this application is currently crashing due to some sort of conflict with HTTP2 and GCP. GCP does not allow HTTP2 traffic unless it is used for TCP. If HTTP2 communication is attempted without TLS GCP will downgrade the connection to http 1.1 and GRPC will not work. I am in the process of adding and testing TLS for the test server in the app and for the client connecting. The fallback position is to skip the GRPC call and just call the xkcd endpoint via a function. The GRPC aspect is not useful except as a way to experiment with GRPC and passing through GRPC calls to regular HTTP endpoints.
This is an overly complicated page in that it uses a GRPC server started by the application which is queried by the handler. The GRPC call itself calls a simple HTTP client which gives the data back. The GRCP client gets the data then the handler sends it as a JSON payload to the page.
The Javascript for this page calls this server requesting metadata about an xkcd cartoon for a day. A random day is selected for each of the 5 divs in this page. (from among the first 2,000 daily cartoons available from the xkcd API). The server calculates a random delay that is used to reload each image using a callback in the page's Javascript. It works well but may be unstable as I work to get GRPC working on GCP.
Although it is a bit tedious to set up a GRPC server it was not too difficult to figure out. TLS is required for GCP and is not a bad idea in any case so that is being used.

Tanning Salon
问题描述 :
Tan Your Hide, Inc., owns several coin-operated tanning salons. Research has shown that if a customer arrives and there are no beds available, the customer will turn around and leave, thus costing the company a sale. Your task is to write a program that tells the company how many customers left without tanning.
输入:
The input consists of data for one or more salons, followed by a line containing the number 0 that signals the end of the input. Data for each salon is a single line containing a positive integer, representing the number of tanning beds in the salon, followed by a space, followed by a sequence of uppercase letters. Letters in the sequence occur in pairs. The first occurrence indicates the arrival of a customer, the second indicates the departure of that same customer. No letter will occur in more than one pair. Customers who leave without tanning always depart before customers who are currently tanning. There are at most 20 beds per salon.
输出:
For each salon, output a sentence telling how many customers, if any, walked away. Use the exact format shown below.
样例输入:
2 ABBAJJKZKZ 3 GACCBDDBAGEE 3 GACCBGDDBAEE 1 ABCBCA 0
样例输出:
All customers tanned successfully. 1 customer(s) walked away. All customers tanned successfully. 2 customer(s) walked away.
解题代码:
//* @author<EMAIL_ADDRESS>import java.util.ArrayList; import java.util.HashSet; import java.util.Scanner; import java.util.Set; public class Main { public static void main(String[] args) { Scanner in = new Scanner(System.in); while (true) { int num = in.nextInt(); if (num == 0) break; String customers = in.next(); int leftCustomer = 0; SetcustomerSet = new HashSet (); for (int i = 0; i < customers.length(); i++) { int size = customerSet.size(); if (size >= num) { if (customerSet.contains(customers.charAt(i))) { customerSet.remove(customers.charAt(i)); continue; } leftCustomer++; int index = customers.indexOf(customers.charAt(i), i + 1); if (index != -1) customers = customers.substring(0, index) + customers.substring(index + 1); } else { if (customerSet.contains(customers.charAt(i))) { customerSet.remove(customers.charAt(i)); } else customerSet.add(customers.charAt(i)); } } if (leftCustomer == 0) System.out.println("All customers tanned successfully."); else System.out.println(leftCustomer + " customer(s) walked away."); } } }

能不能说下这个是用的什么算法策略？
书上的解法更巧妙一些，在九度OJ实测的效率差不多
。。。
有意思，有难度
您没有考虑 树的根节点是负数的情况， 若树的根节点是个很大的负数，那么就要考虑过不过另外一边子树了
感觉这里的评分标准没啥作用阿，反而显得显得赘余，还不如直接去掉好了。
第一句可以忽略不计了吧。从第二句开始分析，说明这个花色下的所有牌都会在其它里面出现，那么还剩下♠和♦。第三句，可以排除2和7，因为在两种花色里有。现在是第四句，因为♠还剩下多个，只有是♦B才能知道答案。
分析的很专业！
很强大啊，佩服
还是有些难度的！
gcc环境
其实国内大部分公司对算法都不够重视。特别是中小型公司老板根本都不懂技术，也不懂什么是算法，从而也不要求程序员懂什么算法，做程序从来不考虑性能问题，只要页面能显示出来就是好程序，这是国内的现状，很无奈。


More Circle
objects could be constructed in the applet,
and their draw()
Circle
ObjectsThe suggested answer is one way to do it. (Another way will be used in a few pages.) Here is the applet, modified to draw three concentric circles:
// assume that the drawing area is 200 by 200 public class TestCircle3 extends Applet { Circle circ1 = new Circle( 100, 100, 10 ); Circle circ2 = new Circle( 100, 100, 20 ); Circle circ3 = new Circle( 100, 100, 30 ); public void paint ( Graphics gr ) { circ1.draw( gr ); circ2.draw( gr ); circ3.draw( gr ); } }
Here is what it draws:
Notice that with the Circle
object
it was much easier to draw concentric
circles than using drawOval()
Although the present definition of the Circle
class is useful,
it needs more work if it is to be used as a drawing tool.

Kiara: "Originally I wanted this to be a Black Lives Matter project. But the actual project came out really colorful and didn’t give me a serious kind of vibe to it. It was pretty slow and chill. Unlike the Black Lives Matter movement which is important and a serious topic. I chose the song because the beat went really well with the color and the moves. It was slow and had a chill colorful tone to me."

I was invited to speak at the 2017 College Board Dream Deferred Conference and brought Rushea along to sit on the panel with me. Rushea talked about her experiences learning CS for the first time and what that meant to her, This is my favorite project because it showed me that I had to be focused and determined to get it done. I started this project in class but I had to finish it at home. Having to finish it when my teacher was not around was when my determination kicked in. There were a lot of times I messed up, and would email Mr. Budi, but when he wouldn't respond right away, I had to learn to just get it done on my own.

When a group of 10th graders in Miami told me they wanted to build a Baby Name Generator I was immediately put off. But as I helped them build this, I noticed something extremely powerful. Go on the app store and search for a baby name generator. You will not find an app that caters to black and carribean names. This example speaks volumes to the importance of diversity in tech.
This app just makes me laugh. It represents the personality, humor, and swagger of teens in Miami. Not only is it aesthetically beautiful, but technically sound. Andrea pushed herself to use the Twilio API so that her app could send text messages. For weeks she came to me after school to work out bugs, get guidance, and just talk through her ideas. It is easily one of my favorite apps.
Dagmawit: I started coding Virtual Reality stuff near the end of my 9th-grade year. This is the second VR project I've built and I wanted to showcase an abstract themed experience incorporating some of my favorite colors and random shapes.

Positions for this body are then contiguous starting at this index. When a floating body is modeled with a quaternion mobilizer (see has_quaternion_dofs()), the four consecutive entries in the state starting at this index correspond to the quaternion that parametrizes this body's orientation.
| std::exception | if called pre-finalize, see MultibodyPlant::Finalize(). |
| int floating_velocities_start | ( | ) | const |
(Advanced) For floating bodies (see is_floating()) this method returns the index of the first generalized velocity in the state vector for a MultibodyPlant model.
Velocities for this body are then contiguous starting at this index.

Somalia: More than half a million people affected by floods
by Aaron BrooksMore than half a million people have been affected by floods in Somalia, according to the latest figures from the United Nations.
Among those, 17 people have been killed and 370,000 people have been displaced with livelihoods being disrupted in the worst-affected areas. The UN Office for the Coordination of Humanitarian Affairs (OCHA) says relief agencies and their partners have reached at least 105,000 flood-affected people in the country but warn significant gaps remain in the delivery of assistance.
More than half a million people affected
The latest OCHA figures show that 547,000 people have been affected in the latest spate of flooding in Somalia. The UN agency said “2019 has been another tumultuous period for Somali farmers after the last 2019 Gu’ season produced southern Somalia’s lowest cereal harvest in decades”.
OCHA says the response from donors and humanitarian groups has been swift but urged donors to keep giving amid a growing food shortage crisis in Somalia.
According to UN figures, there are now 4.8 million food insecure people in Somalia, 1.2 million people in emergency and crisis, as well as 1 million children projected to be malnourished.
The UN set a funding target of $1.1 billion for 2019, of which $822.8 million (76%) has been received. However, time is running out to achieve that target before the turn of the year.

shmat, shmdt - System V shared memory operations
#include <sys/types.h>
#include <sys/shm.h>
void *shmat(int shmid, const void *shmaddr, int shmflg);
int shmdt(const void *shmaddr);
shmat() attaches the System V shared memory segment identified by
shmid to the address space of the calling process. The attaching
address is specified by shmaddr with one of the following criteria:
- If shmaddr is NULL, the system chooses a suitable (unused)
page-aligned address to attach the segment.
- If shmaddr isn't NULL and SHM_RND is specified in
shmflg, the attach occurs at the address equal to shmaddr
rounded down to the nearest multiple of SHMLBA.
- Otherwise, shmaddr must be a page-aligned address at which the
attach occurs.
In addition to SHM_RND, the following flags may be
specified in the shmflg bit-mask argument:
- SHM_EXEC (Linux-specific; since Linux 2.6.9)
- Allow the contents of the segment to be executed. The caller must have
execute permission on the segment.
- SHM_RDONLY
- Attach the segment for read-only access. The process must have read
permission for the segment. If this flag is not specified, the segment is
attached for read and write access, and the process must have read and
write permission for the segment. There is no notion of a write-only
shared memory segment.
- SHM_REMAP (Linux-specific)
- This flag specifies that the mapping of the segment should replace any
existing mapping in the range starting at shmaddr and continuing
for the size of the segment. (Normally, an EINVAL error would
result if a mapping already exists in this address range.) In this case,
shmaddr must not be NULL.
The brk(2) value of the calling process is not altered by
the attach. The segment will automatically be detached at process exit. The
same segment may be attached as a read and as a read-write one, and more
than once, in the process's address space.
A successful shmat() call updates the members of the
shmid_ds structure (see shmctl(2)) associated with the shared
memory segment as follows:
- shm_atime is set to the current time.
- shm_lpid is set to the process-ID of the calling process.
- shm_nattch is incremented by one.
shmdt() detaches the shared memory segment located at the address
specified by shmaddr from the address space of the calling process. The
to-be-detached segment must be currently attached with shmaddr equal to
the value returned by the attaching shmat() call.
On a successful shmdt() call, the system updates the
members of the shmid_ds structure associated with the shared memory
segment as follows:
- shm_dtime is set to the current time.
- shm_lpid is set to the process-ID of the calling process.
- shm_nattch is decremented by one. If it becomes 0 and the segment
is marked for deletion, the segment is deleted.
On success, shmat() returns the address of the attached shared memory
segment; on error, (void *) -1 is returned, and
errno is set to indicate the cause of the error.
On success, shmdt() returns 0; on error -1 is returned, and
errno is set to indicate the cause of the error.
When shmat() fails, errno is set to one of the following:
- EACCES
- The calling process does not have the required permissions for the
requested attach type, and does not have the CAP_IPC_OWNER
capability in the user namespace that governs its IPC namespace.
- EIDRM
- shmid points to a removed identifier.
- EINVAL
- Invalid shmid value, unaligned (i.e., not page-aligned and
SHM_RND was not specified) or invalid shmaddr value, or
can't attach segment at shmaddr, or SHM_REMAP was specified
and shmaddr was NULL.
- ENOMEM
- Could not allocate memory for the descriptor or for the page tables.
When shmdt() fails, errno is set as follows:
- EINVAL
- There is no shared memory segment attached at shmaddr; or,
shmaddr is not aligned on a page boundary.
POSIX.1-2001, POSIX.1-2008, SVr4.
In SVID 3 (or perhaps earlier), the type of the shmaddr
argument was changed from char * into const
void *, and the returned type of shmat() from
char * into void *.
After a fork(2), the child inherits the attached shared memory segments.
After an execve(2), all attached shared memory segments are
detached from the process.
Upon _exit(2), all attached shared memory segments are
detached from the process.
Using shmat() with shmaddr equal to NULL is the
preferred, portable way of attaching a shared memory segment. Be aware that
the shared memory segment attached in this way may be attached at different
addresses in different processes. Therefore, any pointers maintained within
the shared memory must be made relative (typically to the starting address
of the segment), rather than absolute.
On Linux, it is possible to attach a shared memory segment even if
it is already marked to be deleted. However, POSIX.1 does not specify this
behavior and many other implementations do not support it.
The following system parameter affects shmat():
- SHMLBA
- Segment low boundary address multiple. When explicitly specifying an
attach address in a call to shmat(), the caller should ensure that
the address is a multiple of this value. This is necessary on some
architectures, in order either to ensure good CPU cache performance or to
ensure that different attaches of the same segment have consistent views
within the CPU cache. SHMLBA is normally some multiple of the
system page size. (On many Linux architectures, SHMLBA is the same
as the system page size.)
The implementation places no intrinsic per-process limit on the
number of shared memory segments (SHMSEG).
