8 home trends that defined the 2010s, according to an interior designer, Business Insider - Business Insider Singapore
by Samantha Grindell- As the decade comes to a close, it’s a good time to look back on the decor trends that were most popular throughout the 2010s.
- Insider spoke to Ashley Quinn, vice president of creative marketing at Interior Marketing Group, about the interior design trends that defined the decade.
- Quinn pointed to all-white kitchens, accent walls, and the rise of mid-century modern furniture as some of the most popular design trends of the decade.
- She also told Insider that curved sofas were her favorite trend of the 2010s.
- “They’re incredibly versatile, sculptural, and add a touch of mid-century elegance to any room,” Quinn said of rounded couches.
- Visit Insider’s homepage for more stories.
One of the popular decor trends of the 2010s was blue, gray, and other cool colors in homes.
“The design world started to move away from warmer tones and move on to cooler colors as an overall palette,” Ashley Quinn, vice president of creative marketing at Interior Marketing Group, told Insider.
“Say goodbye to the standard beige that was once referred to as ‘builder beige,’ and hello to the cool, calming tones of gray,” she added.
White-on-white kitchens were a fixture of modern design in the 2010s.
“The strongest trend of all that has stood the test of time is the white kitchen,” Quinn said of decor in the last decade.
“It’s timeless, classic, and chic,” she added.
And in those white kitchens, people gravitated towards brass or bronze finishes to add a subtle pop of color.
“There’s been a move away from nickel finishes and onto brass and bronze to help balance those cool walls and fabrics,” Quinn told Insider.
There was a wallpaper renaissance in the 2010s, as well as an interest in accent walls.
Quinn found the wallpaper and accent wall most surprising of all the decor trends that were popular in the last 10 years, and she’s not alone in that opinion.
Interior designer and HGTV star Leanne Ford told Insider that she “can’t get into an accent wall.”
Painted floors also had a moment during the decade.
Floor paint was like an accent wall for the ground, and it was viewed as an easy way to spice up a space.
“I’m pretty sure that painted floors will not be returning,” Quinn told Insider of the trend.
“My favorite decor trend of the last 10 years is the reintroduction of the curved sofa,” Quinn told Insider.
“They’re incredibly versatile, sculptural, and add a touch of mid-century elegance to any room,” Quinn said.
“They can help anchor a living room that’s a difficult shape or add some much-needed curves in a boxy bedroom.”
The 2010s saw the rise of modern design in domestic spaces as well.
Quinn told Insider that the rise in modern design came from a surge of people knowing what was trending, thanks in part to HGTV shows.
“Celebrities and non-celebrities alike over the past ten years have become much more knowledgeable about interior design, design brands, and modern design,” she said.
“Cleaner lines, less ornate wood, and comfort and quality over furniture that no one can actually sit in comfortably are all things that became a top priority over the last decade,” according to Quinn.
And mid-century modern furniture became popular in the last few years of the decade.
“Mid-century furniture seems to have stayed around for the past few years, and I think it’s because of the way they’re being integrated into modern design,” Quinn said of the aesthetic.
“They’re layered with clean, contemporary pieces and updated with beautiful luxe fabrics – making everything feel cohesive.”
For instance, this couch has a retro shape, but the velvet green has a modern edge.


There is a tide in the affairs of men,
Which taken at the flood leads on to fortune.
Omitted, all the voyage of their life,
Is bound in shallows and in miseries.


This package defines what a search node is and some basic queue based algorithms for searching over them.
The basic algorithm is the queue search algorithm that uses a queue to order its search nodes and simply selects the
next node from that queue until the goal state is found.
The max steps algorithm refines this by limiting the search to complete within a maximum number of steps.
The bound algorithm allows some property of the states being searched over to be bounded and to only search up
to that bound.
The iterative bound algorithm allows repeated searching up to a bound that increases iteratively on succesive calls
to the algorithm.
A search is created from these basic algorithms by adding a queue and a search node type to it to produce a search.
For example, a last in first out queue will result in a bradth first search and a last in last out queue will result in
depth first. Simple search nodes do not guide the search but heuristic nodes can be used with ordered queues to produce
more sophisticated searches. For exmaple a greedy search uses heuristic nodes and a queue order on the heuristic values
such that the node with the best heuristic value is always on top of the queue and explored first.

Doubling during the game was introduced into backgammon in 1926 on the playboy circuit of France although automatic doubles (doubling the stakes if both players roll the same starting number) had probably been around for a few years before that.
The method of recording the value of the game at any one point varied until 1930 when the doubling cube was introduced. I have (I believe) one of the only two sets of backgammon matches (made of ivory) that were used for recording purposes before the advent of the doubling cube.
The advent of doubling and the introduction of the chouette around the same time generated a huge increase of interest in backgammon and the game flourished until the start of the Great Depression in 1929. A large number of books were published in the years 1928-1930. Needless to say, none of them had anything really useful to say about doubling, which was very little understood, and was basically a gambling mechanism which was in accord with the mood of the time.
To the best of knowledge nobody wrote down the basic concept of the 25% take point until the “The Backgammon Book” by Jacoby and Crawford was published in 1970. Pip counts scarcely get a mention until that point in time. The Backgammon Book also has the first mention of the term “Beaver”. If you believe you have been incorrectly doubled, you can “beaver” the double by doubling the stakes once more but you keep the cube on your side of the board.
The concept of beavering a beaver (a raccoon) and beavering a raccoon (an aardvark) came later and there is no record of when these additional furry animals were added to the game. Beavers are often played in money games (never in tournaments), raccoons rarely and aardvarks hardly ever.
Over the years I have seen some horrendous doubles which have been summarily dealt with by perfectly correct beavers. Note that the original doubler can drop the beaver if he realises his mistake. I thought I had seen it all until John Clark showed me this week’s position. Black is in the box, owning three cubes on 2 and White has just had to leave his last two checkers exposed. What happened next?
You guessed it! Black (who must remain nameless) redoubled all three players to 4. Two merely accepted but the other player correctly beavered to 8 which Black promptly raccooned to 16 (in for a penny in for a pound).
You may have also guessed by now that Black very unfairly went on to hit and close out the two White checkers and win the game.
Not surprisingly XG rates the redouble as a x20 blunder. Given that Black loses a backgammon 42% of the time I am surprised it is not worse that that. In discussing the position with John he wondered if the original position was too good to beaver! In other words, if Black was beavered would he have an attack of common sense and drop the beaver?
Given the individual involved John knew there was no chance of that actually happening, but it raises the interesting question of whether a position can actually be too good to beaver? I’ll leave you to think about that one.

Hello There!
I discovered my passion for design when I was a sophomore in High School; It was then when it became clear what I wanted to do for a living. I pursued my career at the amazing Valencia College where I started my major in Print Design. A year later I took a begginer’s Web class, where I discovered the love for code. After that, I switched my major to Interactive Design and started the never-ending journey of becoming a web developer along with sharpening my eye for design.

The Honest Guide to Cooking is a labour of love, not a get rich quick scheme. But the original honest guide to cooking was designed as a book, and I thought it would be a shame not to share that with you. Most of the content in the book will be uploaded onto the site and be freely available, but reading the book as a whole is obviously a different experience. Proceeds from the ebook sales will go towards hosting costs for the online version of the honest guide to cooking, and for freeing up some time so I can add and create new content.
Handy buttons in case you already know you want to buy the ebook
The Honest Guide to Cooking ebook containes 128 colourfully illustrated pages about cooking, about learning to love it, to laugh about it, to feel more relaxed about the subject. Here's what it touches on:
The ebook is currently offered as a PDF version that you can read on either your computer or tablet. It will also be available on apple iBooks and Google Play Books in a short while, so if you prefer those formats, it may be worth waiting.
The PDF comes prepackaged with table of contents bookmarks for easier navigation
Yes, the download is handled by Simple Goods who pass the transaction through Stripe - a super safe and widely used payment system. I could offer a PayPal option if you'd prefer but it costs to implement. If you'd like a paypal option, please leave a comment about it below!
Unfortunately not - it's a digital download so once you have the file, you have it and there's no real way for you to give it back. It's kind of like when you buy underwear in a clothes store - no matter how much you try to guarantee you haven't worn it, it's just too hard to tell (although maybe not as unhygienic as that example). If you find an error or something isn't working I'll try my best to help you though. Shoot me an email at<EMAIL_ADDRESS>(please don't be upset if it takes a while for me to get back to you)

Albert AnastasiaAlbert liked to whack.In 1903, a beefy ox of a boy was born in Italy. His name was Umberto Anastasio.  As soon as Albert hit the shore, he had an amazing work ethic. He broke legs, smacked up whores, and rubbed people out morning, noon, and night. By age 14, Albert was already a giant, swarthy bastard, ready to throw down at the drop of a hat. He decided to change the last letter of his last name so his folks wouldn't be embarrassed by his criminal behavior. They must have been proud.
Sweet Sweet Number 18Congress is a harsh mistress. When the 18th Amendment was ratified in 1919, Albert started working for Joe Adonis, helping keep shipments of booze safe from armed alcoholics. Adonis built himself a nice little reputation as a gentleman bootlegger, while Anastasia stood behind him with a couple of gats. For the better part of the 20's, Anastasia procured truckloads of liquor for Adonis. Typically, this meant he stood on the side of the road with some gorilla's he'd shaved waiting for booze trucks to pass by.An unusual number of those shaved gorillas were circumcised. Anastasia himself wasn't Jewish, but he had a particular camaraderie with Jews that surfaced constantly throughout his career. After he helped kill Joe Masseria alongside Vito Genovese, Joe Adonis, and the Hebrew Bugsy Siegel, Albert became the boss of a new kind of business. Murder Inc. was the disposal end of Lucky Luciano's National Crime Syndicate, and when Albert took over, it was mostly staffed with Jewish hitmen from Brownsville. This was a sign of the new order of the mafia; an integrated mob that no longer cared about the origin of the killer: only the talent.
Admurderstrative AssistantThis desk job at Murder Inc. did not keep Albert's hands clean. He was a sloppy sociopath who helped kill anyone he felt needed special attention. Anastasia personally garotted Peter Panto, a longshoreman intent upon pushing the mob out of the Brooklyn docks. He killed Panto not only to protect mob interests, but also to help out his brother Anthony, who ran the Longshoreman's union.When Dutch Schultz demanded Thomas Dewey be killed in order to preserve his slot machine empire, Anastasia was the guy who took the job. He borrowed a toddler from a neighbor and sat outside Dewey's apartment on Fifth Avenue. After three days of watching the district attorney and bouncing the boy on his knee, Anastasia drew up a plan to present to Schultz. But Albert knew better than to simply take orders from the Dutchman. He alerted Lucky Luciano to the plan before returning to Schultz. The affair ended with the Dutchman at the other end of a Murder Inc. gun, and Dewey square in line for promotions all the way to a failed run for president. The National Crime Syndicate had decided the heat from killing Dewey would be too dangerous, and instead opted to off the loud-mouthed Schultz, who no one liked anyway.
No, Don Bluthe's Cartoon is Not About Albert.The 1940's brought change to the US Syndicate. Abe "Kid Twist" Reles began to testify against members of Murder Inc. at the start of that year, sending mafia lowlifes scurrying for cover. He even told the feds about Peter Panto.Before Reles could testify in front of a judge, however, he fell from his sixth floor suite at the hotel where the police were holding him. Anastasia was safe, but not out of the public eye. To keep the heat off, Anastasia signed up to help fight Hitler. He enlisted in the US army and insured himself American citizenship by rising to the rank of Sergant. He was stationed in Georgia, and thanks to heavy bribes in his favor, never saw a day of combat. He never even left the US. But that didn't stop him from marching through Brooklyn wearing medal's he'd bought and stolen while in the infantry. Anastasia regaled his fellow mobsters with war stories for years after World War II ended. If anyone knew he was lying, they certainly didn't have the stones to call him on it. Albert became a big wig in New York when Joe Adonis decided to retire. From 1946 on, Anastasia steadily rose in power by assuming control of Adonis' operations. In 1951, Anastasia felt he was powerful enough to topple the Mangano family bosses, and killed the brothers, Vincent and Phillip Mangano. Everyone knew he'd done it, but they just let him have control because, on the whole, Anastasia played well with others when it came to the rackets.
It's Good to be the kingWith power came psychosis. Anastasia's underlings began referring to him as the Mad Hatter. He was prone to fits of rage and would order hits on people simply because he was having a bad day.Once, while watching TV, Anastasia saw a news report about Arnold Schuster. Schuster had called the police to inform them that he had seen infamous bank robber Willie Sutton getting off a New York subway. Anastasia was furious. "I can't stand squealers," he screamed at the TV, "Hit that guy!" And so, on March 8, 1952, that guy got hit.  That was enough to warrant murder.
Yes, But Was He Nixon Bad?Despite the constant killing, Anastasia was a regular family man. He was home to his wife every night by nine, and spent lots of time with his children. So Albert was never quite ruthless enough to catch Vito Genovese. He was a cold hearted killer, an unabashed criminal, and a major mafia boss, but Vito Genovese was a conniving, unpredictable, and vicious bastard.On October 25, Anastasia awakened early and headed to the city for his day's work. He kissed his wife and hopped in his car. His body-guard had called in sick so Albert had to drive himself. By 10:25 AM, Albert was in the basement of the Park Sheraton hotel in Manhattan, sitting in a barber's chair waiting for a shave and a haircut. It cost a bit more than two bits. As Anastasia laid back and closed his eyes for a snooze, two gunmen walked in. The older of them, Carlo Gambino raised his gun and shot Anastasia three times. Anastasia, stood up and began to charge his assailants. This only resulted in him losing most of his hands and arms to bullets. After 10 shots, Anastasia was dead. Later that day, Vito Genovese took his position as head of the crime family that would eventually become known as the Gambino family. |

A coffee drink made with espresso and steamed milk. The term as used in English is a shortened form of the Italian caffè latte, caffelatte or caffellatte, which means "milk coffee"
Individual-sized, baked quick bread product.
"A rich, moist muffin packed with whole wheat, oatmeal, raisins, carrots, pineapple, coconut, and a cream cheese surprise baked right in the center! Great for breakfast and kids love them! I vary the recipe depending what I have on hand and it always works out great. Hope you enjoy!"
Small, flat, sweet, baked good, usually containing flour, eggs, sugar, and either butter, cooking oil or another oil or fat.
"Using butter (NOT margarine) is essential for the success of this rich, but highly addictive cookie! You may need as little as 3 cups confectioners' sugar for the icing; just stop adding it when you've reached the desired consistency."
Fried dough confectionery or dessert food. The doughnut is popular in many countries and prepared in various forms as a sweet snack that can be homemade or purchased in bakeries, supermarkets, food stalls, and franchised specialty outlets.
"This recipe is very quick and easy to make. I have a donut pan, which is like a muffin pan, but has donut shaped holes rather than muffin shaped holes. These donuts are baked not fried, so they don't have so many calories. I mix up either a powdered sugar glaze or a chocolate icing to top these with. They can also be rolled in cinnamon and white sugar, but it doesn't stick very well. My husband likes them just plain. For a chocolate glaze, simply stir 1/2 cup melted chocolate chips into the glaze mixture."
Dough of flour, water and shortening that may be savoury or sweetened. Sweetened pastries are often described as bakers' confectionery.
"This is a recipe that my family has created for a portable breakfast. It uses a bread machine for the dough preparation. The filling can be with a variety of things. We like the sausage, cheese, and hash browns for a breakfast meal. I prepare the recipe by filling the kolaches the night before, and keeping them in the refrigerator overnight. In the morning, I set out the kolaches to warm to room temperature while the oven is preheating, and then cook them for a quick, hot breakfast."
Small cake designed to serve one person, which may be baked in a small thin paper or aluminum cup.
"This hearty pumpkin cupcake with a cinnamon-cream cheese frosting is good in the fall or any other time of the year."


| Home > Documentation > Developing > Tutorials > Developing Web applications > Developing JavaServer faces applications > Developing a Simple JavaServer Faces application |
This application will make you understand how Model (M), View (V), Controller (C) architecture is implemented in JavaServer Faces. This application will make use of UI components, Validator, Navigation and Bean component available with JSF.
This application will take a user First Name and Last Name. Later these fields will be validated by JSF and using the controller bean and Navigation rule the output will be displayed. This application will also introduce a UI component which is a submit button.
To run this tutorial, as a minimum you will be required to have installed the following prerequisite software:
Geronimo version 2.1.x, Java 1.5 runtime, and Eclipse Ganymede are used is used in this tutorial but other versions can be used instead (e.g., Geronimo version 2.2, Java 1.6, Eclipse Europa)
Details on installing eclipse are provided in the Development environment section. This tutorial is organized in the following sections:
Once you have all the prerequisites installed, follow the following steps to create a project with Eclipse.
The Model as suggested by MVC architecture handles data and logic of the application. In an enterprise application. Java Beans are used to represent collection of data and operation on that data. In JSF we use Java Beans to define the Model.
WebContent/WEB-INF/faces-config.xml
. Double click on the file. This will open the Faces Configuration Editor.login.jsp
. Select Finish.welcome.jsp
.myfaces-html.tld
and myfaces_core.tld
to this folder.login.jsp
and welcome.jsp
with data
login.jsp
defines two tag libraries
The code <f:validateLength minimum="4" maximum="10"/> defines the input text length to be minimum of 4 characters and maximum of 10 characters. This is the standard validation provided by core tag libraries. Other examples of validators are Validate Long Range tag, Validate Double Range tag , and so on. JSF also provides a Validator interface which can be implemented to create custom validators.
The code <h:message for="" style="color: red;"/> defines the error message. When the user inputs the controller validates each of the inputs. If the inputs are invalid Controller displays the same page again with an error message for the errors. The color:red suggests that the error message will be displayed in red color.
This step uses the JSP page navigation in the order of user inputs and validation by controller. If all the inputs are valid than the controller performs the action as suggested by the HTML form. This action is submitted by the HTML form as a command button.
The code in the input.jsp
<h:commandButton id="submit" action="validated" value="Enter" /> checks to determine if all the inputs are valid. This is the button which submits the form to controller if all inputs are valid. In this case the commandButton tells the controller to execute the validated action if all the inputs are valid.
The pages navigation in a JSF applicaiton is defined by faces-config.xml
. Follow the steps before to define the pages navigation.
faces-config.xml
login.jsp
as shown in the figure and select OK.welcome.jsp
page on the Navigation Rule window. See the figure below:faces-config.xml
. This rule instructs the Controller that if all the inputs are valid from a form in the /pages/login.jsp
, and the action is validated, then go to page /pages/welcome.jsp
.index.jsp
under WebContent as follows:
login.jsf
in the forward path tag. If you look at the web.xml
, *.jsf is used as the URL pattern to suggest that forwarded page be taken care by Java Server Faces Servlet.Right click on the project SimpleJSF and select Run As -> Run On Server. This will deploy the sample on the Apache Geronimo Server and a Login page will be launched.
Lets give some sample inputs:
Sample Input #1:
First Name: Mickey
Last Name: Mouse
Both the First Name as well as Last Name fulfills the validation rules, so this form will be submitted to controller and according to the navigation rule controller will launch a welcome.jsp
page.
Sample Input #2:
First Name: Mic
Last Name: Mouse
First Name should be minimum of length=4 but in this case First Name is of length=3. In this case validation will fail and an error message will be generated by controller for First Name field.
Sample Input #3:
First Name: Mickey
Last Name: Mo
Last Name should be minimum of length=3 but in this case Last Name is of length=2. In this case validation will fail and an error message will be generated by controller for Last Name field.

After seven hours of staggering around London's Palace Hotel drunk as a lord, Kiefer Sutherland loses control at the sight of the hotel's 12-foot Christmas tree.  "The tree HAS to come down."
Kiefer warned staff: "I'm smashing it -- can I pay for it?"
A staff member replied: "I'm absolutely sure you can, sir."
The Lost Boys star -- famously ditched by Julia Roberts five days before their wedding in 1991 -- then hurled himself into the Norwegian Spruce, sending baubles and lights crashing to the ground. Pulling pine needles out of his hair and t-shirt, he said to a hotel employee: "Ooh, sorry about that... You're so cool.

MPI implementations can optionally group performance and control variables into categories to express logical relationships between various variables. For example, an MPI implementation could group all control and performance variables that refer to message transfers in the MPI implementation and thereby distinguish them from variables that refer to local resources such as memory allocations or other interactions with the operating system.
Categories can also contain other categories to form a hierarchical grouping. Categories can never include themselves, either directly or transitively within other included categories. Expanding on the example above, this allows MPI to refine the grouping of variables referring to message transfers into variables to control and to monitor message queues, message matching activities and communication protocols. Each of these groups of variables would be represented by a separate category and these categories would then be listed in a single category representing variables for message transfers.
The category information may be queried in a fashion similar to the mechanism for querying variable information. The MPI implementation exports a set of N categories via the MPI tool information interface. If N=0, then the MPI implementation does not export any categories, otherwise the provided categories are indexed from 0 to N-1. This index number is used in subsequent calls to functions of the MPI tool information interface to identify the individual categories.
An MPI implementation is permitted to increase the number of categories during the execution of an MPI program when new categories become available through dynamic loading. However, MPI implementations are not allowed to change the index of a category or delete it once it has been added to the set.
Similarly, MPI implementations are allowed to add variables to categories, but they are not allowed to remove variables from categories or change the order in which they are returned.
The following function can be used to query the number of categories, N.
| MPI_T_CATEGORY_GET_NUM(num_cat) | |
| OUT num_cat | current number of categories (integer) |
int MPI_T_category_get_num(int *num_cat)
Individual category information can then be queried by calling the following function:
int MPI_T_category_get_info(int cat_index, char *name, int *name_len, char *desc, int *desc_len, int *num_cvars, int *num_pvars, int *num_categories)
The arguments name and name_len are used to return the name of the category as described in Section Convention for Returning Strings .
The routine is required to return a name of at least length one. This name must be unique with respect to all other names for categories used by the MPI implementation.
If any OUT parameter to MPI_T_CATEGORY_GET_INFO is a NULL pointer, the implementation will ignore the parameter and not return a value for the parameter.
The arguments desc and desc_len are used to return the description of the category as described in Section Convention for Returning Strings .
Returning a description is optional. If an MPI implementation decides not to return a description, the first character for desc must be set to the null character and desc_len must be set to one at the return of this call.
The function returns the number of control variables, performance variables and other categories contained in the queried category in the arguments num_cvars, num_pvars, and num_categories, respectively.
If the name of a category is equivalent across connected processes, then the returned description must be equivalent.
| MPI_T_CATEGORY_GET_INDEX(name, cat_index) | |
| IN name | the name of the category (string) |
| OUT cat_index | the index of the category (integer) |
int MPI_T_category_get_index(const char *name, int *cat_index)
MPI_T_CATEGORY_GET_INDEX is a function for retrieving the index of a category given a known category name. The name parameter is provided by the caller, and cat_index is returned by the MPI implementation. The name parameter is a string terminated with a null character.
This routine returns MPI_SUCCESS on success and returns MPI_T_ERR_INVALID_NAME if name does not match the name of any category provided by the implementation at the time of the call.
Rationale.
This routine is provided to enable fast retrieval of a category index by
a tool, assuming it knows the name of the category for which it is looking.
The number of categories exposed by the implementation can change over time,
so it is not possible for the tool to simply iterate over the list of
categories once at initialization. Although using MPI implementation
specific category names is not portable across MPI implementations,
tool developers may choose to take this route for lower overhead at runtime
because the tool will not have to iterate over the entire set of categories to
find a specific one.
( End of rationale.)
| MPI_T_CATEGORY_GET_CVARS(cat_index, len, indices) | |
| IN cat_index | index of the category to be queried, in the range [0,N-1] (integer) |
| IN len | the length of the indices array (integer) |
| OUT indices | an integer array of size len, indicating control variable indices (array of integers) |
int MPI_T_category_get_cvars(int cat_index, int len, int indices[])
MPI_T_CATEGORY_GET_CVARS can be used to query which control variables are contained in a particular category. A category contains zero or more control variables.
| MPI_T_CATEGORY_GET_PVARS(cat_index, len, indices) | |
| IN cat_index | index of the category to be queried, in the range [0,N-1] (integer) |
| IN len | the length of the indices array (integer) |
| OUT indices | an integer array of size len, indicating performance variable indices (array of integers) |
int MPI_T_category_get_pvars(int cat_index, int len, int indices[])
MPI_T_CATEGORY_GET_PVARS can be used to query which performance variables are contained in a particular category. A category contains zero or more performance variables.
| MPI_T_CATEGORY_GET_CATEGORIES(cat_index, len, indices) | |
| IN cat_index | index of the category to be queried, in the range [0,N-1] (integer) |
| IN len | the length of the indices array (integer) |
| OUT indices | an integer array of size len, indicating category indices (array of integers) |
int MPI_T_category_get_categories(int cat_index, int len, int indices[])
MPI_T_CATEGORY_GET_CATEGORIES can be used to query which other categories are contained in a particular category. A category contains zero or more other categories.
As mentioned above, MPI implementations can grow the number of categories as well as the number of variables or other categories within a category. In order to allow users of the MPI tool information interface to check quickly whether new categories have been added or new variables or categories have been added to a category, MPI maintains a virtual timestamp. This timestamp is monotonically increasing during the execution and is returned by the following function:
| MPI_T_CATEGORY_CHANGED(stamp) | |
| OUT stamp | a virtual time stamp to indicate the last change to the categories (integer) |
int MPI_T_category_changed(int *stamp)
If two subsequent calls to this routine return the same timestamp, it is guaranteed that the category information has not changed between the two calls. If the timestamp retrieved from the second call is higher, then some categories have been added or expanded.
Advice to users.
The timestamp value is purely virtual and only intended to check for changes in
the category information. It should not be used for any other purpose.
( End of advice to users.)
The index values returned in indices by
MPI_T_CATEGORY_GET_CVARS,
MPI_T_CATEGORY_GET_PVARS and
MPI_T_CATEGORY_GET_CATEGORIES
can be used as input to MPI_T_CVAR_GET_INFO,
MPI_T_PVAR_GET_INFO and
MPI_T_CATEGORY_GET_INFO, respectively.
The user is responsible for allocating the arrays passed into the functions MPI_T_CATEGORY_GET_CVARS, MPI_T_CATEGORY_GET_PVARS and MPI_T_CATEGORY_GET_CATEGORIES. Starting from array index 0, each function writes up to len elements into the array. If the category contains more than len elements, the function returns an arbitrary subset of size len. Otherwise, the entire set of elements is returned in the beginning entries of the array, and any remaining array entries are not modified.

Elektra
0.8.17

This plugin is a type checker plugin using the CORBA
data types.
A common and successful type system happens to be CORBA with IDL. The system is outstanding because of the many mappings it provides to other programming languages.
The type checker plugin supports all basic CORBA types: short
, unsigned_short
, long
, unsigned_long
, long_long
, unsigned_long_long
, float
, double
, char
, boolean
, any
and octet
. In Elektra octet
is the same as char
. When checking any it will always be successful, regardless of the content. Elektra also added other types. empty
will only yield true if there is no value. string
allows any non-empty sequence of octets.
Sometimes the type should expresses that, for example, both an empty or another type is valid. In Elektra a space-separated list of types expresses that. If any of those types match, the whole type is valid. For example, the type string empty
equals the type any
. This facility builds a union of the sets of instances existing types specify.
enum
works with a list of choices. Any of these choices confirms to the type, others do not. For example, the type FSType accepts all file system names, for example, ext2, jfs or vfat.
The CORBA
type system goes far beyond these basic types. In IDL, it is also allowed to define classes, interfaces and generic containers. These user-defined types are however not useful on a single Key.
To sum up, many basic types like int or char are convenient and CORBA ensures that they can be converted to the specific type of the programming language.
The CORBA
type system also has its limits. The types string
and enum
, however, can be unsatisfactory. While string is too general and makes no limit on how the sequence of characters is structured, the enumeration is too finite. For example, it is not possible to say that a string is not allowed to have a specific symbol in it.

Dequeue.
A double-ended queue or deque (pronounced “deck”)
is a generalization of a
stack and a queue that supports adding and removing items
from either the front or the back of the data structure.
Create a generic data type Deque
that implements the following API:
public class Deque<Item> implements Iterable<Item> { // construct an empty deque public Deque() // is the deque empty? public boolean isEmpty() // return the number of items on the deque public int size() // add the item to the front public void addFirst(Item item) // add the item to the back public void addLast(Item item) // remove and return the item from the front public Item removeFirst() // remove and return the item from the back public Item removeLast() // return an iterator over items in order from front to back public Iterator<Item> iterator() // unit testing (required) public static void main(String[] args) }
Corner cases. Throw the specified exception for the following corner cases:
IllegalArgumentException
if the client calls either addFirst()
or addLast()
with a null
argument.
java.util.NoSuchElementException
if the client calls either removeFirst()
or removeLast
when the deque is empty.
java.util.NoSuchElementException
if the client calls the next()
method in the iterator when there are no more items to return.
UnsupportedOperationException
if the client calls
the remove()
method in the iterator.
Unit testing.
Your main()
method must call directly every public constructor and method
to help verify that they work as prescribed (e.g., by printing results to standard output).
Performance requirements. Your deque implementation must support each deque operation (including construction) in constant worst-case time. A deque containing n items must use at most 48n + 192 bytes of memory. Additionally, your iterator implementation must support each operation (including construction) in constant worst-case time.
Randomized queue.
A randomized queue is similar to a stack or queue, except that
the item removed is chosen uniformly at random among items in
the data structure.
Create a generic data type RandomizedQueue
that implements the following API:
public class RandomizedQueue<Item> implements Iterable<Item> { // construct an empty randomized queue public RandomizedQueue() // is the randomized queue empty? public boolean isEmpty() // return the number of items on the randomized queue public int size() // add the item public void enqueue(Item item) // remove and return a random item public Item dequeue() // return a random item (but do not remove it) public Item sample() // return an independent iterator over items in random order public Iterator<Item> iterator() // unit testing (required) public static void main(String[] args) }
Iterator. Each iterator must return the items in uniformly random order. The order of two or more iterators to the same randomized queue must be mutually independent; each iterator must maintain its own random order.
Corner cases. Throw the specified exception for the following corner cases:
IllegalArgumentException
if the client calls
enqueue()
with a null
argument.
java.util.NoSuchElementException
if the client calls either sample()
or
dequeue()
when the randomized queue is empty.
java.util.NoSuchElementException
if the client calls the next()
method in the iterator when there are no more items to return.
UnsupportedOperationException
if the client calls
the remove()
method in the iterator.
Unit testing.
Your main()
method must call directly every public constructor and method to
verify that they work as prescribed (e.g., by printing results to standard output).
Performance requirements.
Your randomized queue implementation must support each randomized queue operation
(besides creating an iterator) in constant amortized time.
That is, any intermixed sequence of m randomized queue operations (starting from
an empty queue) must take at most cm steps in the worst case,
for some constant c.
A randomized queue containing n items must use at most
48n + 192 bytes of memory.
Additionally, your iterator implementation must support
operations next()
and hasNext()
in constant worst-case time;
and construction in linear time; you may (and will need to) use a
linear amount of extra memory per iterator.
Client.
Write a client program Permutation.java
that takes an integer k as
a command-line argument; reads a sequence of strings from standard input
using StdIn.readString()
; and prints exactly k of them,
uniformly at random.
Print each item from the sequence at most once.
~/Desktop/queues> cat distinct.txt A B C D E F G H I ~/Desktop/queues> java Permutation 3 < distinct.txt C G A ~/Desktop/queues> java Permutation 3 < distinct.txt E F G ~/Desktop/queues> cat duplicates.txt AA BB BB BB BB BB CC CC ~/Desktop/queues> java Permutation 8 < duplicates.txt BB AA BB CC BB BB CC BB
Your program must implement the following API:
public class Permutation { public static void main(String[] args) }
Command-line argument. You may assume that 0 ≤ k ≤ n, where n is the number of string on standard input. Note that you are not given n.
Performance requirements.
The running time of Permutation
must be linear in the size of the input.
You may use only a constant amount of memory plus either
one Deque
or RandomizedQueue
object of maximum size at most n.
(For an extra challenge and a small amount of extra credit,
use only one Deque
or RandomizedQueue
object of maximum size at most k.)
Web submission.
Submit a .zip file containing only
RandomizedQueue.java
, Deque.java
, and
Permutation.java
.
Your submission may not call library functions except those in
StdIn
,
StdOut
,
StdRandom
,
java.lang
,
java.util.Iterator
,
and
java.util.NoSuchElementException
.
In particular, do not use either
java.util.LinkedList
or
java.util.ArrayList
.


She's a killer queen dynamite with a laser beam Drop Dead Gorgeous
by Ross Anthony
Once you get used to the "Fargo" accents, "Drop Dead" will prove amusing and apt in accomplishing what it sets out to do.
A mock-doc (feigned-documentary), this film spoofs a teen beauty pageant in Mount Rose, Minnesota. The documentary crew follows contestants and judges through the days just prior and following the city finals. To push things over the edge of silliness, someone is knocking off (as in killing) potential teen winners; hence the exceedingly clever title of the movie. In fact, this may just be the most appropriately titled movie of the year.
 The ironic coupling of religion, arms and teenage girls in The Lutheran Sisterhood Gun Club. A past queen in all her Hollywood stardom sells St. Paul pork products. Anorexic reigning queen lip-sincs Melissa Manchester's "Don't cry out loud" from her wheelchair. And last but not least, the top contestant tap dances to Industrial Rock music.
It's simply silly fun.
Starring Kirsty Alley, Kirsten Dunst, Denise Richards, and Ellen Barkin. Directed by Michael Patrick Jann. Written by Lona Williams. Produced by Gavin Polone and Judy Hofflund at New Line. Rated PG-13.

Dutch Olympic athlete jailed for drug trafficking
AMSTERDAM (Reuters) - Dutch Olympic athlete Madiea Ghafoor has been sentenced to eight-and-a-half years in jail after 2 million pounds ($2.58 million) worth of ecstasy tablets and crystal meth were found in the boot of her car in Germany, DPA news agency has reported.
Ghafoor, 27, was stopped at a border check in Elten in June where 50kg of ecstasy, 2kg of crystal meth and 11,950 euros in cash were seized by police, the report said.
The athlete, who ran for the Netherlands in the 4x400m relay at the 2016 Olympic Games, pleaded not guilty to the charges at Kleve District Court and said she thought she was carrying doping materials, the German news agency said.
The Dutch Athletics Union said it was shocked by the case and would investigate Ghafoor’s claim concerning doping materials to ascertain who else might have been involved.
“We are stunned by the judgment,” a statement on the organization’s website said. “With the ruling of the German court, the Athletics Union rejects the actions of Ghafoor.
“The Athletics Union condemns any use or trade in doping or drugs and fully commits itself to the Dutch doping law.
“The case has been transferred to the Doping Authority to investigate the extent to which the doping legislation has been violated.”
Ghafoor refused to reveal who she was transporting the drugs for and said she feared for the safety of her family, DPA said.

Standardize / Normalize / Z-score / Scale
The standardize()
function allows you to easily scale and center all numeric variables of a dataframe. It is similar to the base function scale()
, but presents some advantages: it is tidyverse-friendly, data-type friendly (i.e., does not transform it into a matrix) and can handle dataframes with categorical data.
library(psycho)
library(tidyverse)
z_iris <- iris %>%

| Design and Implementation of a validating XML parser in Haskell: Master's thesis; University of Applied Sciences Wedel | ||
|---|---|---|
| Prev | Appendix A. User handbook | Next |
Unfortunately the XML parser of the Haskell XML Toolbox does not support fully the XML 1.0 specification at the moment. We are working hard to implement the missing features in the near future.
Missing features:
Namespaces are not supported.
Protocols like "http" and "file" are not yet supported due to a lack of libraries. We think of using the curl command instead.
General external entities are not yet processed.
General entities in default values of attributes are not yet substituted.
Known problems:
Line numbers are not yet reported for validity constraint errors.

 And now, O Lord, remember me and look favourably upon me; do not punish
me for my sins and for my unwitting offences and those which my fathers
committed before you. For we disobeyed your commandments, and you gave us over
to plunder, captivity, and death; you made us the talk, the byword, and an
object of reproach in all the nations among which you have dispersed us. And
now your many judgments are true in exacting penalty from me for my sins and
those of my fathers, because we did not keep your commandments. For we did not walk in truth before you. And now deal with
me according to your pleasure; command my spirit to be taken up, that I may be
released from the face of the earth and become dust. For it is better for me to
die than to live, because I have heard false reproaches, and great is the
sorrow within me. Command that I now be released from my distress; release me
to go to the eternal abode; and do not, O Lord, turn your face away from
me." For it is better for me to die than to see so much distress in my
life and to listen to such insults.” On the same day, at

FIRST READING 2 Timothy 1:1-3.6-12
The beginning of the second Letter of Saint Paul to Timothy
Paul, an apostle of Christ Jesus by the will of God
according to the promise of the life which is in Christ Jesus, To Timothy, my
beloved child: Grace, mercy, and peace from God the Father and Christ Jesus our
Lord. I thank God whom I serve with a clear conscience, as did my fathers, when
I remember you constantly in my prayers. For this reason I remind you to
rekindle the gift of God that is within you through the laying on of my hands;
for God did not give us a spirit of timidity but a spirit of power and love and
self-control. Do not be ashamed then of testifying to our Lord, nor of me his
prisoner, but share in suffering for the gospel in the power of God, who saved
us and called us with a holy calling, not in virtue of our works but in virtue
of his own purpose and the grace which he gave us in Christ Jesus ages ago, and
now has manifested through the appearing of our Saviour Christ Jesus, who
abolished death and brought life and immortality to light through the gospel.
For this gospel I was appointed a preacher and apostle and teacher, and
therefore I suffer as I do. But I am not ashamed, for I know whom I have
believed, and I am sure that he is able to guard until that Day what has been
entrusted to me.

GOSPEL Mark 12:18-27
A reading from the holy Gospel according to Mark
At that time: Sadducees came to Jesus, who say that there is no resurrection; and they asked him a question, saying, "Teacher, Moses wrote for us that if a man's brother dies and leaves a wife, but leaves no child, the man must take the wife, and raise up children for his brother. There were seven brothers; the first took a wife, and when he died left no children; and the second took her, and died, leaving no children; and the third likewise; and the seven left no children. Last of all the woman also died. In the resurrection whose wife will she be? For the seven had her as wife." Jesus said to them, "Is not this why you are wrong, that you know neither the scriptures nor the power of God? For when they rise from the dead, they neither marry nor are given in marriage, but are like angels in heaven. And as for the dead being raised, have you not read in the book of Moses, in the passage about the bush, how God said to him, 'I am the God of Abraham, and the God of Isaac, and the God of Jacob? He is not God of the dead, but of the living; you are quite wrong."

--- layout: post title: "Adding Real-Time To A RESTful Rails App" date: 2013-02-27 comments: true ---
After rewriting Understoodit several times I’ve spent a lot of time thinking about building real-time web applications. While I elected to rewrite 100% of Understoodit in Node, there are many existing Rails and Sinatra applications that can’t be completely rewritten, but could still benefit with the addition of real-time updates. The tutorial below starts with a traditional web-app written in Backbone and Ruby on Rails (RoR). Of course the modifications could easily be applied to any (Backbone|Angular|Ember) and (Rails|Sinatra|Django|Pylons) app.
Between the overview below, and the code on GitHub, you should be able to follow along and, in less than 50 lines of code, add real-time updates to your Rails app.
In a traditional web app if a user creates a new model other users must refresh their page to see that content. Alternatively, you could poll the server every 30 second and refetch all the content. With both approaches you end up fetching all the content, and in the first case the markup as well.
In Figure 1, User 1 creates a new book, but User 2 will not see that new book unless they refresh their page.
When User 1 creates a new book, we’d like that new book to be pushed to User 2 in real-time. I’m going to cover one method that requires only a few modifications to your existing app and uses Redis, Node and Socket.IO.
The advantage of this approach is that it only requires tiny modifications to a Rails' model, and if your Node server crashes, your application will work as it always has (without real-time). Thus, I’d consider this a real-time enhancement that gracefully degrades to a conventional Rails RESTful web app.
First, ensure that socket.io.js
has been added to lib/assets/javascripts
, and referenced in app/assets/javascripts/application.js. In the web app create a new module, called realtime, that includes the Socket.IO connection code. When the application initializes it calls app.realtime.connect()
to setup the Socket.IO connection.
In the root of the Rails app create a new folder called 'realtime', where the Node server will reside. Don't forget to create a package.json
file and include socket.io, and redis in the dependencies. Finally, remember to run npm install
.
Assuming you have Redis installed, add redis to your Gemfile. Next, create a file called redis.rb
in your initializers with the following content:
The Rails app now has access to Redis through the $redis
global variable. Below, we publish changes to Redis whenever a model is created, updated or destroyed. Changes are published to "rt-change", which our Node.js connections are listening to (see above).
In the Books Collection, we add the code to both listen for 'books' events and the handler to handle those events. For create, we simply add the new object (obj) to the collection. For update we update the existing model, while for destroy we remove the object from the collection.
```javascript app.collections.Books = Backbone.Collection.extend({ model : app.models.Book, url : '/books', initialize: function(){ app.on('books', this.handle_change, this); }, handle_change : function(message){ var model; switch(message.action){ case 'create': this.add(message.obj); break; case 'update': model = this.get(message.id); model.set(message.obj); break; case 'destroy': this.remove(message.obj); } } }); ```In production there are many edge cases to consider. For instance, if someone views your app on their mobile phone and then puts the phone in their pocket, the screen saver goes on and Socket.IO will disconnect. When the user takes the phone out of their pocket, and views the app, Socket.IO will reconnect. However, during the period of disconnection the data in the client-side app may have become out-of-date. An easy fix is just to fetch the data on reconnect. With lots of connections, or lots of data, fetching everything becomes problematic and requires a more clever method for fetching data (e.g. just fetch the new, or changed, data).
Another issue is if two people are editing the same item, and if person 1 clicks save that will replace what person 2 is editing. To solve this you can present person 2 with a message saying that the book they are editing has been updated by someone else and prevent the version of the book they are editing from being replaced. This isn't an ideal solution, but would be fine if the chances of two people editing the same model were minimal.
In the code above there is only one channel 'rt-change', meaning every connected client will get every real-time change. You may want to scope your channels by user (e.g. rt-change/[USERID]). Furthermore, you'd want to create one redis client for every Socket.IO connection (currently there's one redis client for all connections). In other words the .createClient()
, and redis.subscribe('...')
, would have to take place within the Socket.IO 'connection' callback (after line 6 above).
Mike Atlas created a realtime gem which does all the above with minimal setup.
Socket.IO could be swapped for SockJS, which uses a similar API to websockets. I've heard from several individuals that it's significantly more stable than the current version of Socket.IO and it's currently used by Meteor.
Guillermo Rauch, the creator of Socket.IO, has publically stated that Socket.IO's approach of starting with websockets and falling back to polling creates issues. As result, he's been working on Engine.IO, which will power Socket.IO version 1.0, and should provide a much more stable experience. I suspect Socket.IO, v1.0, will be released in the next few months.
Rails 4.0, which is due to be released soon, will include streaming. Using a combination of Rails 4 streaming, and Puma, you could potentially remove Node and Socket.IO, and use Rails for real-time. Of course, you'd have to take care of some of what Socket.IO does such as reconnects and heart-beats.
Redis' Pub/Sub functionality could be replaced by either RabbitMQ or ZeroMQ. I ended up using Redis, since I was using it for caching, and it has an extremely simple API for pub/sub. While RabbitMQ and ZeroMQ appear more complex, they do offer many more features for messaging.
If you're not keen on tinkering with Node, or waiting for Rails 4, there are commercial options such as Pusher and PubNub, that deal with real-time connections for you. While both options can be pricey, especially with many concurrent connections, they do save you the hassle of building the infrastructure yourself.
Adding real-time updates to your Ruby on Rails RESTful app has never been easier. Over the next few months Rails 4, or Socket.IO v1.0, will make the process even more painless. As Google's services make users more accustomed to real-time updates, it becomes even more important to provide a similar experience in your webapps.


With this animation I wanted to re-create Pacman eating his orbs. I created my own sprite sheet using dimensions 1000 x 100, so each sprite is 100 x 100. I used keyframes to run my animation with the keyframes playing at “.38” seconds for the 10 steps. I made the animation set to “infinite” so it would go on forever.
