IV
She was still quite angry when she came out of the dressing–room and crossed the intervening parlor of politeness that opened onto the hall—angry not so much at the actual happening which was, after all, the merest commonplace of her social existence, but because it had occurred on this particular night. She had no quarrel with herself. She had acted with that correct mixture of dignity and reticent pity which she always employed. She had succinctly and deftly snubbed him.
It had happened when their taxi was leaving the Biltmore—hadn't gone half a block. He had lifted his right arm awkwardly—she was on his right side—and attempted to settle it snugly around the crimson fur–trimmed opera cloak she wore. This in itself had been a mistake. It was inevitably more graceful for a young man attempting to embrace a young lady of whose acquiescence he was not certain, to first put his far arm around her. It avoided that awkward movement of raising the near arm.
His second faux pas was unconscious. She had spent the afternoon at the hairdresser's; the idea of any calamity overtaking her hair was extremely repugnant—yet as Peter made his unfortunate attempt the point of his elbow had just faintly brushed it. That was his second faux pas. Two were quite enough.
He had begun to murmur. At the first murmur she had decided that he was nothing but a college boy—Edith was twenty–two, and anyhow, this dance, first of its kind since the war, was reminding her, with the accelerating rhythm of its associations, of something else—of another dance and another man, a man for whom her feelings had been little more than a sad–eyed, adolescent mooniness. Edith Bradin was falling in love with her recollection of Gordon Sterrett.
So she came out of the dressing–room at Delmonico's and stood for a second in the doorway looking over the shoulders of a black dress in front of her at the groups of Yale men who flitted like dignified black moths around the head of the stairs. From the room she had left drifted out the heavy fragrance left by the passage to and fro of many scented young beauties—rich perfumes and the fragile memory–laden dust of fragrant powders. This odor drifting out acquired the tang of cigarette smoke in the hall, and then settled sensuously down the stairs and permeated the ballroom where the Gamma Psi dance was to be held. It was an odor she knew well, exciting, stimulating, restlessly sweet—the odor of a fashionable dance.
She thought of her own appearance. Her bare arms and shoulders were powdered to a creamy white. She knew they looked very soft and would gleam like milk against the black backs that were to silhouette them to–night. The hairdressing had been a success; her reddish mass of hair was piled and crushed and creased to an arrogant marvel of mobile curves. Her lips were finely made of deep carmine; the irises of her eyes were delicate, breakable blue, like china eyes. She was a complete, infinitely delicate, quite perfect thing of beauty, flowing in an even line from a complex coiffure to two small slim feet.
She thought of what she would say to–night at this revel, faintly prestiged already by the sounds of high and low laughter and slippered footsteps, and movements of couples up and down the stairs. She would talk the language she had talked for many years—her line—made up of the current expressions, bits of journalese and college slang strung together into an intrinsic whole, careless, faintly provocative, delicately sentimental. She stalled faintly as she heard a girl sitting on the stairs near her say: "You don't know the half of it, dearie!"
 She dropped her arms to her side until they were faintly touching the sleek sheath that covered and suggested her figure. She had never felt her own softness so much nor so enjoyed the whiteness of her own arms.
"I smell sweet," she said to herself simply, and then came another thought "I'm made for love."
She liked the sound of this and thought it again; then inevitable succession came her new–born riot of dreams about Gordon. The twist of her imagination which, two months before, had disclosed to her her unguessed desire to see him again, seemed now to have been leading up to this dance, this hour.
For all her sleek beauty, Edith was a grave, slow–thinking girl. There was a streak in her of that same desire to ponder, of that adolescent idealism that had turned her brother socialist and pacifist. Henry Bradin had left Cornell, where he had been an instructor in economies, and had come to New York to pour the latest cures for incurable evils into the columns of a radical weekly newspaper.
Edith, less fatuously, would have been content to cure Gordon Sterrett. There was a quality of weakness in Gordon that she wanted to take care of; there was a helplessness in him that she wanted to protect. And she wanted someone she had known a long while, someone who had loved her a long while. She was a little tired; she wanted to get married. Out of a pile of letters, half a dozen pictures and as many memories, and this weariness, she had decided that next time she saw Gordon their relations were going to be changed. She would say something that would change them. There was this evening. This was her evening. All evenings were her evenings.
Then her thoughts were interrupted by a solemn undergraduate with a hurt look and an air of strained formality who presented himself before her and bowed unusually low. It was the man she had come with, Peter Himmel. He was tall and humorous, with horned–rimmed glasses and an air of attractive whimsicality. She suddenly rather disliked him—probably because he had not succeeded in kissing her.
"Well," she began, "are you still furious at me?"
"Not at all."
She stepped forward and took his arm.
"I'm sorry," she said softly. "I don't know why I snapped out that way. I'm in a bum humor to–night for some strange reason. I'm sorry."
"S'all right," he mumbled, "don't mention it."
He felt disagreeably embarrassed. Was she rubbing in the fact of his late failure?
"It was a mistake," she continued, on the same consciously gentle key. "We'll both forget it." For this he hated her.
A few minutes later they drifted out on the floor while the dozen swaying, sighing members of the specially hired jazz orchestra informed the crowded ballroom that "if a saxophone and me are left alone why then two is com–pan–ee!"
A man with a mustache cut in.
"Hello," he began reprovingly. "You don't remember me."
"I can't just think of your name," she said lightly—"and I know you so well."
"I met you up at—" His voice trailed disconsolately off as a man with very fair hair cut in. Edith murmured a conventional "Thanks, loads—cut in later," to the inconnu.
The very fair man insisted on shaking hands enthusiastically. She placed him as one of the numerous Jims of her acquaintance—last name a mystery. She remembered even that he had a peculiar rhythm in dancing and found as they started that she was right.
"Going to be here long?" he breathed confidentially.
She leaned back and looked up at him.
"Couple of weeks."
"Where are you?"
"Biltmore. Call me up some day."
"I mean it," he assured her. "I will. We'll go to tea."
"So do I—Do."
A dark man cut in with intense formality.
"You don't remember me, do you?" he said gravely.
"I should say I do. Your name's Harlan."
"No–ope. Barlow."
"Well, I knew there were two syllables anyway. You're the boy that played the ukulele so well up at Howard Marshall's house party.
"I played—but not—"
A man with prominent teeth cut in. Edith inhaled a slight cloud of whiskey. She liked men to have had something to drink; they were so much more cheerful, and appreciative and complimentary—much easier to talk to.
"My name's Dean, Philip Dean," he said cheerfully. "You don't remember me, I know, but you used to come up to New Haven with a fellow I roomed with senior year, Gordon Sterrett."
Edith looked up quickly.
"Yes, I went up with him twice—to the Pump and Slipper and the Junior prom."
"You've seen him, of course," said Dean carelessly. "He's here to–night. I saw him just a minute ago."
Edith started. Yet she had felt quite sure he would be here.

"Why—hello there—"
She slipped, stumbled lightly.
"I'm sorry, dear," she murmured mechanically.
She had seen Gordon—Gordon very white and listless, leaning against the side of a doorway, smoking, and looking into the ballroom. Edith could see that his face was thin and wan—that the hand he raised to his lips with a cigarette, was trembling. They were dancing quite close to him now.
"—They invite so darn many extra fellas that you—" the short man was saying.
"Hello, Gordon," called Edith over her partner's shoulder. Her heart was pounding wildly.
His large dark eyes were fixed on her. He took a step in her direction. Her partner turned her away—she heard his voice bleating——
"—but half the stags get lit and leave before long, so—" Then a low tone at her side.
"May I, please?"
She was dancing suddenly with Gordon; one of his arms was around her; she felt it tighten spasmodically; felt his hand on her back with the fingers spread. Her hand holding the little lace handkerchief was crushed in his.
"Why Gordon," she began breathlessly.
"Hello, Edith."
 She loved him—she knew she loved him—then for a minute there was silence while a strange feeling of uneasiness crept over her. Something was wrong.
Of a sudden her heart wrenched, and turned over as she realized what it was. He was pitiful and wretched, a little drunk, and miserably tired.
"Oh—" she cried involuntarily.
His eyes looked down at her. She saw suddenly that they were blood–streaked and rolling uncontrollably.
"Gordon," she murmured, "we'll sit down; I want to sit down."
They were nearly in mid–floor, but she had seen two men start toward her from opposite sides of the room, so she halted, seized Gordon's limp hand and led him bumping through the crowd, her mouth tight shut, her face a little pale under her rouge, her eyes trembling with tears.
She found a place high up on the soft–carpeted stairs, and he sat down heavily beside her.
"Well," he began, staring at her unsteadily, "I certainly am glad to see you, Edith."
She looked at him without answering. The effect of this on her was immeasurable. For years she had seen men in various stages of intoxication, from uncles all the way down to chauffeurs, and her feelings had varied from amusement to disgust, but here for the first time she was seized with a new feeling—an unutterable horror.
"Gordon," she said accusingly and almost crying, "you look like the devil."
He nodded, "I've had trouble, Edith."
"Trouble?"
"All sorts of trouble. Don't you say anything to the family, but I'm all gone to pieces. I'm a mess, Edith."
His lower lip was sagging. He seemed scarcely to see her.
"Can't you—can't you," she hesitated, "can't you tell me about it, Gordon? You know I'm always interested in you."
She bit her lip—she had intended to say something stronger, but found at the end that she couldn't bring it out.
Gordon shook his head dully. "I can't tell you.  I can't tell a good woman the story."
"Rot," she said, defiantly. "I think it's a perfect insult to call any one a good woman in that way. It's a slam. You've been drinking, Gordon."
"Thanks." He inclined his head gravely. "Thanks for the information."

"Do you think drinking's going to make it any better?"
"What you doing—trying to reform me?"
"No; I'm trying to help you, Gordon. Can't you tell me about it?"
"I'm in an awful mess. Best thing you can do is to pretend not to know me."
"Why, Gordon?"
"I'm sorry I cut in on you—its unfair to you.  Here, I'll get some one else to dance with you."
He rose clumsily to his feet, but she reached up and pulled him down beside her on the stairs.
"Here, Gordon.  You're hurting me.  I'm a little crazy. Something's wrong with me, Edith. There's something left me. It doesn't matter."
"It does, tell me."
"Just that. I was always queer—little bit different from other boys. All right in college, but now it's all wrong.  I'm very gradually going loony."
He turned his eyes full on her and began to laugh, and she shrank away from him.
"What is the matter?"
"Just me," he repeated. "I'm going loony. This whole place is like a dream to me—this Delmonico's—"
As he talked she saw he had changed utterly. He wasn't at all light and gay and careless—a great lethargy and discouragement had come over him. Revulsion seized her, followed by a faint, surprising boredom. His voice seemed to come out of a great void.
"Edith," he said, "I used to think I was clever, talented, an artist. Now I know I'm nothing. Can't draw, Edith. Don't know why I'm telling you this."
She nodded absently.
"I can't draw, I can't do anything. I'm poor as a church mouse." He laughed, bitterly and rather too loud.  I'm a failure. I'm poor as hell."
Her distaste was growing. She barely nodded this time, waiting for her first possible cue to rise.

"Edith," he said, turning to her with what was evidently a strong effort at self–control, "I can't tell you what it means to me to know there's one person left who's interested in me."
He reached out and patted her hand, and involuntarily she drew it away.
"It's mighty fine of you," he repeated.
"Well," she said slowly, looking him in the eye, "any one's always glad to see an old friend—but I'm sorry to see you like this, Gordon."
There was a pause while they looked at each other, and the momentary eagerness in his eyes wavered. She rose and stood looking at him, her face quite expressionless.
"Shall we dance?" she suggested, coolly.
—Love is fragile—she was thinking—but perhaps the pieces are saved, the things that hovered on lips, that might have been said. The new love words, the tendernesses learned, are treasured up for the next lover.

I prefer this more than hang out. It is really busy at home it means so many things to do at home.
The most interesting time shopping. It is not really tired when we lokking for the new items. I can realize the reason why I work.

Find some nice cafe and spend time in there such as writing diary and reading a book, it is happiness!
Also it is hard to meet firends in working day, so we need to meet people in weekend. Make happy memories with firends.

George of the Jungle ˜ Tarzan for Toddlers
George of the Jungle might have tickled my funny bone when I was a wee lad. His place is forever etched deep in my memory, lying somewhere where Curious George and Amelia Bedelia also roam.  I couldn't stop laughing, but my parents could never quite appreciate the slapstick silliness.
For better or worse, that quality hasn't changed. An animated opening recounts how George, as a baby, wound up in the Buvuku jungle, in the heart of Africa. He is befriended and raised by an assortment of animals, including Ape, who is a scholarly, talking gorilla; Tookie-Tookie, a toucan; and Shep, an elephant. George (Brendan Fraser) grows up to be the guardian and self-proclaimed king of the jungle. Yet despite his physical prowess, when it comes to vine-swinging, he is navigationally challenged. You'll hear more than a few disconcerting "thuds" in this movie.
We are also introduced to Ursula (Leslie Mann), a sweet but meek socialite who is rethinking her engagement to the snooty Lyle Van de Groot (Thomas Haden Church) while exploring the lush Buvuku. During her expedition, she is threatened by a lion. George saves her and takes her back to his treehouse. The result is a slowly developing love story between the city girl and the jungle boy. But mostly, this is a movie that incorporates dozens of slapstick moments. For example, we see George receiving sex education from a gorilla. We watch Lyle try in vain to outwit George. We see two bumbling poachers try to kidnap (apenap?) Ape so that they can cash in on this talking phenomenon. And we see George, who has been taken back to America by Ursula, try to adapt to his modern surroundings. One especially funny scene involves George watching a TV commercial that equates falling with love with having lots and lots of coffee. Mistaking this as a weapon of woo, George immediately and voraciously munches on all the coffee that he can find in the house. The caffeine buzz makes him hyper, and he runs out into the streets of his concrete jungle, where more silliness ensues.
Yet, while the movie does have it's funny moments, it became obvious to me that I had outgrown the silliness and the shenanigans of George and his jungle pals. Yes, I have become my parents. It should be noted, however, that Fraser is physically agile, boyishly appealing and brings good comic timing to the role. And, to Disney's credit, all of the children in the theatre were laughing and enjoying the jokes and the humor of it all. However, while the portions were just right for the young ones, adults will find this fare not very filling.

Since fiddling around with a sequence of property values is somewhat uncomfortable
in all known UNO language bindings (especially for tasks like simply changing the value
of an existing value), the Settings property wraps the Info
property for easier single-value access.
You should use the Setting property if you need to access a few properties only,
and the Info property if you need access to all existent settings at once.
The object represented by this property supports the ::com::sun::star::beans::PropertyBag
service. That is, you can at runtime add arbitrary new properties to the bag.
Additionally, the property bag supports default values of properties, and thus the
::com::sun::star::beans::XPropertyState interface. If you add an own property to
the bag using ::com::sun::star::beans::XPropertyContainer::addProperty, you need
to specifiy an initial value, which is also used as default value (exceptions see below).
Effectively, the property bag represented by Settings
contains two classes of properties:
Pre-defined ones and user-defined ones.
Pre-defined properties are properties which are potentially used by the data source, the
application UI for the data source, or a particular backend driver employed by the data source. There's
a large set of such properties, no all of them are effectively used for a concrete data source, nonetheless,
they're all present in the Settings
.
Such properties are not removeable from the bag, that is, their
::com::sun::star::beans::PropertyAttribute::REMOVEABLE attribute is not set.
Usually, you'll find that all of this properties have the
::com::sun::star::beans::PropertyState::PropertyState_DEFAULT_VALUE state.
User-defined properties are the ones which are added at runtime by any instance. They might or might
not be removeable, this depends on whether or not the code adding them specifies the
::com::sun::star::beans::PropertyAttribute::REMOVEABLE attribute. Also, they might
or might not have a default value, determined by the
::com::sun::star::beans::PropertyAttribute::MAYBEDEFAULT attribute at the time they're added
to the bag.
When a data source is made persistent, then properties which are not removeable (which are assumed to be the
pre-defined properties) are ignored when they are in DEFAULT
state. All other properties are
always made persistent, except when an explicit
::com::sun::star::beans::PropertyAttribute::TRANSIENT attribute prohibits this.
Similar, when you obtain the Info property of a DataSource
, the
Settings
bag is asked for all its property values, and the ones which are removeable and
in state default are stripped, and not returned in the Info
sequence.

PRINCESS CARABOO A film review by Steve Rhodes Copyright 1995 Steve Rhodes
RATING (0 TO ****): ***
Want to really relax and see an enchanting upbeat movie? Want to see a movie that gives you the feeling you had when you were a small child reading books about faraway kingdoms? Interested in true stories that feel like fairy tales? How about a movie that you can take your kids (say 8 or older) to see but are not kid's movies? Like good acting? Like mysteries? Like Masterpiece Theater type flicks set in rural England? Want to be spellbound? Well, you need to see PRINCESS CARABOO.
 Wrong all around.
PRINCESS CARABOO is based on a true story from the early 1800s in rural England. It seems a princess from a faraway land has escaped capture on a ship in the Bristol channel. The princess (play perfectly by Phoebe Cates) speaks no English. A local professor (well done by John Lithgow) does the research on her language to determine her small country.
The princess comes to live in a large manor house where the butler (played very funnily by Kevin Klein) does not believe her, but the owners (Jim Broadbent and Wendy Hughes) do. A local reporter (excellently done by Stephen Rea from THE CRYING GAME) finds her absolutely fascinating and enchanting--as I am quite sure you will too. The reporter is not sure if her story is true or false and he sets out to determine the facts.
The mysterious princess has many adventures after the plot set up. The mystery in the story does work even though it is a simple one. Cates acting really carries the day. It is almost impossible not to like her--a lot.
The script was written by the director, Michael Austin, and I think you will find several surprises since I suspect most people do not know obscure English history of over 150 years ago. The pacing was good and the casting of all parts, even the most minor, was well done.
This is not GANDHI, but for what it is, I have no complains or suggested improvements in the movie at all. A fun and delightful time at the movies.
PRINCESS CARABOO runs 1:34 and is rated PG for a five-second 3/4 naked leg scene. There is no profanity. I have no idea how it avoided getting a G other than you would need to be about 7 or 8 to like it I think. I recommend it to every one except Ebenezer Scrooge. I think young girls would especially like it, but I can attest to the fact that males would like this show too. I give it ***.
**** = 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.

{% extends "group/base.html" %} {% block title %}Merge Group{% endblock %} {% block content %} {% import "macros.inc.html" as macros %}
Moves all resources from one group into another, and deletes the original ("from") group.


This article will introduce the application model and make it work without a vDOM, using only component local state and the valerie framework. This is the second in a series which starts here.
The code for this example is here: valerie/tree/state-feature/examples/tictactoe
Valerie under the hood§
Valerie defines a Node
struct which implements a tree of references to DOM elements, augmented with the
additional information needed for owned attributes and callbacks.
The philosophy is all Arc<Mutex<...>>
all the time which is great for threading but, I suspect, needs some
serious thinking and testing to ensure that there aren't latent data races waiting in hiding. This work may have
been done.
Events are communicated using channels provided by the
futures_intrusive
crate. This crate is sophisticated and
complete, lock_api
aware, and valerie mostly makes use of one key part: state_broadcast_channel
.
There is a simple DOM builder macro - no RSX yet.
Setting up a game§
This sets up the main DOM and parallel data structure and inserts it into the body
element.
#[valerie(start)]
pub fn run() {
App::render_single(game());
}
fn game() -> Node {
div!(
div!(
board()
).class("game-board"),
div!(
div!(),
ol!()
).class("game-info")
).class("game").into()
}
The most important function call is to board()
and the rest of the divs just mirror the React tutorial
structure, but aren't used.
Board with component local state§
Valerie uses a bundle of State*
structs which are mutable and, in turn, propagate their changes through
channels. These are very similar to Redux state containers.
We can use generics to pass specific types through these channels. The specific types are the Model of our application, playing to Rust's strength as a strongly-typed language.
The game board is an array of nine squares which can be in one of a defined set of states, modelled as an
enumerated type called Square
.
#[derive(Copy, Clone, PartialEq)]
enum Square {
Empty,
X,
O,
}
fn board() -> Node {
let squares: [StateAtomic<Square>; 9] = [
// Can't use array init shorthand because StateAtomic is not Copy
StateAtomic::new(Square::Empty),
StateAtomic::new(Square::Empty),
StateAtomic::new(Square::Empty),
StateAtomic::new(Square::Empty),
StateAtomic::new(Square::Empty),
StateAtomic::new(Square::Empty),
StateAtomic::new(Square::Empty),
StateAtomic::new(Square::Empty),
StateAtomic::new(Square::Empty),
];
We need some other state to manage the game - whether the game is being played or has been won, and the player whose turn is next.
let status = StateAtomic::new(Status::Playing);
let next_player = StateAtomic::new(Square::X);
Status
is another simple enum.
#[derive(Copy, Clone, PartialEq)]
enum Status {
Playing,
Won,
}
Each square will spawn an instance of an async function which will listen for clicks on the receiver end of its channel. We also pass clones of the game state so that the function can control the game.
for square in &squares {
execute(turn_checker(squares.to_vec(), square.rx(), next_player.clone(), status.clone()));
}
The DOM for the board is straight-forward. The status
and next_player
can be displayed by simply
cloning the StateAtomic
instance inline into the DOM. Changes through the transmitter are applied to the
DOM element automatically. The DOM for each square is delegated to a square function.
div!(
div!(
status.clone(),
next_player.clone()
).class("status"),
div!(
square(squares[0].clone(), status.clone(), next_player.clone()),
square(squares[1].clone(), status.clone(), next_player.clone()),
square(squares[2].clone(), status.clone(), next_player.clone())
).class("board-row"),
div!(
square(squares[3].clone(), status.clone(), next_player.clone()),
square(squares[4].clone(), status.clone(), next_player.clone()),
square(squares[5].clone(), status.clone(), next_player.clone())
).class("board-row"),
div!(
square(squares[6].clone(), status.clone(), next_player.clone()),
square(squares[7].clone(), status.clone(), next_player.clone()),
square(squares[8].clone(), status.clone(), next_player.clone())
).class("board-row")
).into()
The square is simple - each is a button of class "square"
. When clicked, a closure runs which changes
the squares's state if the square is empty and the game is still being played. We just read the clones of the
StateAtomics
with value()
. Changing the square's state with put(...)
will send the value to
the StateAtomic
and all the cloned receivers, including the one we passed to the turn_checker.
fn square(state: StateAtomic<Square>, status: StateAtomic<Status>, next_player: StateAtomic<Square>) -> Node {
button!(state.clone())
.class("square")
.on_event("click", (), move |_, _| {
if status.value() == Status::Playing && state.value() == Square::Empty {
state.put(next_player.value());
}
})
.into()
}
Types can be rendered into the HTML element if they implement Display
. Since the next player is not rotated
when we win, we just change the prompt to show the next player or who won (ok ok).
impl Display for Square {
fn fmt(&self, f: &mut Formatter<'_>) -> Result {
let s = match self {
Square::Empty => "",
Square::X => "X",
Square::O => "O",
};
write!(f, "{}", s)
}
}
impl Display for Status {
fn fmt(&self, f: &mut Formatter<'_>) -> Result {
let s = match self {
Status::Playing => "Next player: ",
Status::Won => "Winner: ",
};
write!(f, "{}", s)
}
}
This wraps up the DOM setup.
The turn checker§
This is the turn checker. It is an async function which sets up a loop to process each change to a square. We check if there are any complete lines in the clone of the full board sent to the function, and either set the winner, or flip the next player using rotate.
async fn turn_checker(squares: Vec<StateAtomic<Square>>, rx: StateReceiver<Channel>, next_player: StateAtomic<Square>, status: StateAtomic<Status>) {
fn calculate_winner(squares: &Vec<Square>) -> bool {
const LINES: [[usize; 3]; 8] = [
[0, 1, 2],
[3, 4, 5],
[6, 7, 8],
[0, 3, 6],
[1, 4, 7],
[2, 5, 8],
[0, 4, 8],
[2, 4, 6],
];
for [a, b, c] in &LINES {
let a = squares[*a];
let b = squares[*b];
let c = squares[*c];
if a != Square::Empty && a == b && a == c {
return true;
}
}
return false;
}
let mut old = StateId::new();
while let Some((new, _)) = rx.receive(old).await {
let squares: Vec<Square> = squares.iter().map(|s| s.value()).collect();
if calculate_winner(&squares) {
status.put(Status::Won);
} else {
next_player.put(next_player.value().rotate());
}
old = new;
}
}
impl Square {
pub fn rotate(self) -> Self {
match self {
Square::X => Square::O,
Square::O => Square::X,
_ => self
}
}
}
Valerie does afford us the opportunity to stratify the app according to Model/Model-View/View lines.
What is happening here?§
Each instance of board()
is using something akin to component local state to create Arc<Mutex<...>>
objects which are owned by the main loop Node
tree. These objects are connected by associated channel
end-points which can be transmitted through during DOM events. An async function can monitor receiver end-points
to take higher-level actions.
More importantly though, we are passing around a domain model tightly-defined with Rust enums
and
impl
functions.
We have moved the React tutorial away from a stringly-typed model, significantly improving reliability and maintainability.
Next§
Next we are going to look at what it might be like to lift the component-local state in StateAtomic
up to App State,
and start to see shared data views and the foundations of a back-end.

UK PM Johnson extends lead over Labour Party: Panelbase poll
LONDON (Reuters) - Prime Minister Boris Johnson’s Conservative Party extended its lead over the opposition Labour Party to 13 points this week, according to a Panelbase poll on Friday.
The poll, conducted after the Brexit Party said it would not stand in Conservative-held seats at the December 12 election, put the Conservatives on 43%, up 3 points from a poll last week, ahead of Labour who were unchanged at 30%.
The poll of 1,021 people was carried out between Nov. 13 and 14.

Alec the Geek
bitten the bullet and upgraded from MS Office 2004 (for the Mac) to Office 2008
Well the much vaunted Office 2008 has turned into a damp squib for me. There have been two improvements:
- When replying to messages the fonts don't become so small that you can't read them
- I can check colleagues diaries when booking a meeting
And that's it!
Personally I am pretty disappointed and look forward to ditching Office in the next couple of weeks


ProFTPD-1.3.6c
Installation of ProFTPD
For security reasons, you should install ProFTPD using an unprivileged user and group.
As the root
user:
groupadd -g 46 proftpd &&
useradd -c proftpd -d /srv/ftp -g proftpd \
-s /usr/bin/proftpdshell -u 46 proftpd &&
install -v -d -m775 -o proftpd -g proftpd /srv/ftp &&
ln -v -s /bin/false /usr/bin/proftpdshell &&
echo /usr/bin/proftpdshell >> /etc/shells
Install ProFTPD as an unprivileged
user by running the following commands:
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var/run &&
make
This packages does not come with a usable test suite.
Now, as the root
user:
make install &&
install -d -m755 /usr/share/doc/proftpd-1.3.6c &&
cp -Rv doc/* /usr/share/doc/proftpd-1.3.6c
Command Explanations
install -v -d -m775 -o proftpd -g
proftpd /srv/ftp: Create the home directory for
ProFTPD.
ln -v -s /bin/false
/usr/bin/proftpdshell: Set the default shell as a
link to an invalid shell.
echo /usr/bin/proftpdshell >>
/etc/shells: Fake a valid shell for compatibility
purposes.
Note
The above two commands can be omitted if the following directive
is placed in the configuration file:
RequireValidShell off
By default, proftpd will require that users logging in have valid
shells. The RequireValidShell directive turns off this
requirement. This is only recommended if you are setting up your
FTP server exclusively for anonymous downloads.
Note
Support for most of the dependency packages requires using
options passed to the configure script. View the
output from ./configure
--help for complete information about enabling
dependency packages.

Lucky escape from car wreckers for abandoned kittens
There was a lucky escape for two kittens who were found in a vehicle ready for demolition at a Wellington car wrecker.
The 3-week-old kittens were spotted on Wednesday at the car wrecker's yard by an eagle-eyed worker.
The team spotted a kitten sitting precariously on the seat edge of a Mitsubishi Lancer, that had had its doors removed and was stacked on top of another car.
The team jumped into action and rescued the young kittens just in time.
SPCA's Wellington Centre has taken the kittens into their care and fittingly named them "Mitsi" and "Lancer".
Central Region manager Ros Alsford said the team wasn't sure how the pair ended up in the wrecker's yard.
"Mitsi and Lancer could have become separated from their mum and lost. Either way they are incredibly lucky to be alive."
Alsford said the duo were healthy and were being given around the clock care from a foster family.
"This is one of the more shocking stories of survival that we've seen. We are so grateful Mitsi and Lancer were found and that SPCA can help them on their road to recovery," Alsford said.
"Mitsi and Lancer are only 3-weeks-old, but already life has been quite a ride for them. At this age they are particularly vulnerable to disease, starvation and injury."
The kittens would still need several weeks of care before being big enough to be desexed and adopted.

This page presents a Javascript program that solves the N-Queens problem using a very simple Genetic Algorithm.
Genetic Algorithm pseudocode:
1) Create random individuals and compute fitness value. 2) For each generation: 2.1) Catastrophe? (first 10% of generations are catastrophe-free; catastrophe probability: 5%) 2.1.1) Remove all individuals. 2.1.2) Create random individuals and compute fitness value. 2.2) Keep top 10% individuals (based on fitness) and remove the others. 2.3) Create new individuals by mutating the remaning (swap Queen positions). 2.4) For each individual: 2.4.1) Compute new fitness value based on the number of collisions between Queens. 2.4.2) Fitness value is zero? (no collisions) <IP_ADDRESS>) Solution Found.
Each individual is a group of (x,y)
coordinates that represent the position of each Queen on the board. Individual 1324

Week 1 Blog 2
Kitchen vs. Table

I think watching this video confirmed that I made the right decision in choosing to attend DBC. My impression of DBC is that it's a place where it's not just about teaching you how to code. It's about teaching how to think like a developer. They teach you the culture, how to work together with other developers, and many other valuable skills. I can't wait to learn about this culture and be immersed in it.
I'm excited to be in this kind of learning environment. However, I think the video hit spot on about my insecurities about being completely new to programming. Everything Shereef said applies to me, that I'm afraid I would be the slowest learner and I would be dragging my cohort down. I will need to remember that it will be a great learning experience to work with people with very different backgrounds, and that I will be valuable to others as well.


Defined in Module impact.sound, inherits from ig.Class
ig.music.add( 'music/track1.ogg' ); ig.music.add( 'music/track2.ogg' ); ig.music.add( 'music/track3.ogg' ); ig.music.volume = 0.5; ig.music.play();
ig.Music
offers capabilities to play a list of background music in ordered or random fashion.
An instance of ig.Music
is automatically created at ig.music
(lowercase) by the ig.main()
function.
The index of the current track in the .tracks array.
The instance of ig.Sound that is currently playing. null
if .tracks is empty.
Wheter the current track should be looped instead of jumping to the next track. If there is only one track in the .tracks
array, this property is ignored. The default is false
.
If true
, tracks are played in random order. The default is false
.
An array of instances of ig.Sound to be played back.
The volume for all music tracks from 0.0
to 1.0
. The default is 1
.
Adds the given track
to the .tracks
array and sets .currentTrack to this one, if it is the first track to be added.
track
can be either an instance of ig.Sound
or the filename and path to a sound file. You should load all sound files as class properties, to make sure they are loaded by the preloader. See Working with Assets.
New in 1.19
Use the optional name
parameter to specify a name for the track. Named tracks can be played with the .play() method.
Linearly fade out the current track over time
seconds.
When the fade out is complete, .stop() is called and the volume for this track is reset to it's original volume.
Stops the current track and jumps to the next track in the .tracks
array. If .random
is true, the next track is chosen randomly.
Pauses the current track.
Starts playing the current track.
New in 1.19
Use the optional name
parameter to directly jump to and play a named track. The name can be specified when calling .add().
Stops the current track. Same as .pause(), but additionally "rewinds" the track to the beginning.

A robust framework for solving equations is a salient feature of any Computer Algebra System. An important idea in this regard is “Rewriting and Decomposition”. By using this techniques, we try to reduce the given equation to a set of simpler equations which can be solved with relative ease.
An example here would be the best way to establish the significance of the above idea.
If we have to solve for x
in the equation f(x) = 0
, where
f(x) = ln(x)**2 - 3*ln(x) + 2
This problem can be approached with the idea of “Decomposition and Rewriting”. Here is the procedure:
-
Decomposition The step involves a decomposition of the given function into smaller, constituent functions. In the above case, we decompose f(x) as:
f(x) = g(x)*2- 3*g(x) + 2
, whereg(x) = ln(x)
-
Rewriting Substituting
g(x)
with a dummy variablet
inf(x)
, we get a polynomial int
:
h(t) = (t -1)*(t-2)
, wheret = ln(x)
-
We determine the values which satisfy the equation
h(t) = 0
.
For our example:t = 1
ort = 2
-
Back-substituting the value of
t
into these solutions, we get 2 independent equations inx
:
ln(x)= 1
orln(x) = 2
-
Solving these equations individually, we get the desired solutions of the inital equation
f(x) = 0
i.e.
x = exp(1)
orx = exp(2)
Thus, we get two possible solutions of the given complex transcendental equation through the methods of Rewriting and Decomposition. An important observation can be made with respect to the relative ease of calculating the solutions of the intermediate equations compared to that of the original equation. This motivates the development of a simpler and modular system for solving equations rather than a vast and case-specific one.
A well-designed implementation of the above technique can be of high value to the solveset
system. This will be my task for the 1st week of GSoC. I created a Pull Request PR#11141 with a primitive design.
Reviews and suggestions are welcomed !
Thats pretty much it for now. In the next blog post, I will be writing in detail about the implementation process.

find_and_count_touching_cells.Rmd
The count_touching_cells
function uses morphological analysis of nuclear and membrane segmentation maps to find touching cells of paired phenotypes. It reports the number of touching cells found and, optionally, writes image files showing the touching cells.
count_touching_cells
uses the results of inForm cell segmentation to determine which cells are touching. It uses both nuclear and membrane segmentation to determine the extent of each cell.
count_touching_cells
processes a single field and multiple pairs of phenotypes. The specification of pairs and phenotypes is flexible to accommodate any requirement. The simplest case uses the phenotype names from inForm to select cells. For this case, only the pairs
argument is needed.
For example, this code finds and visualizes touches between CK+
and CD8+
cells, and also between CK+
and CD68+
cells:
library(phenoptr)
cell_seg_path <- sample_cell_seg_path()
pairs <- list(
c('CK+', 'CD8+'),
c('CK+', 'CD68+')
)
colors <- list('CK+'='cyan', 'CD8+'='yellow', 'CD68+'='magenta')
count_touching_cells(cell_seg_path, pairs, colors)
## # A tibble: 2 x 9
## slide_id source phenotype1 phenotype2 total1 total2 p1_touch_p2
## <chr> <chr> <chr> <chr> <dbl> <dbl> <dbl>
## 1 Set4_1-~ Set4_~ CK+ CD8+ 2257 228 148
## 2 Set4_1-~ Set4_~ CK+ CD68+ 2257 417 250
## # ... with 2 more variables: p2_touch_p1 <dbl>, touch_pairs <dbl>
For more flexibility, create new compound phenotypes using the phenotype_rules
argument. For example, this code repeats the previous analysis limiting it to tumor cells with PDL1 above a threshold. Note that phenotype_rules
only needs to include definitions for phenotypes which don’t match the names in pairs
.
Using purrr::map
, you can find touching cells for all cell seg data files in a single directory.
# Directory containing data files
base_path <- '/path/to/data'
# A subdirectory for the results
output_base <- file.path(base_path, 'touches')
# All cell seg data files in base_path
files <- list_cell_seg_files(base_path)
# Count and visualize touching cells
touch_counts <- purrr::map_df(files, function(path) {
cat('Processing', path, '\n')
count_touching_cells(path, pairs, colors, phenotype_rules,
output_base=output_base)
})
The result of the above is a tibble
which may be written to a CSV file:
touches_path <- file.path(output_base, 'TouchCounts.csv')
readr::write_csv(touch_counts, touches_path)
phenoptrExamples
package demonstrates aggregation across multiple fields from multiple samples.


This is a fairly esoteric test for measurements used by Monocle's Column Dimensions — essentially the paginater class.
Probably best to ignore this test.

try redis
Redis, or Remote Dictionary Server, is something that has intrigued me since my first small project in TGA. I built a simple website called Receptacle that used data stored nested at only one level, i.e. key value pairs for keeping track of what kind of bins different kinds of recyclables and wastes get placed into.
As the site is currently constructed, it preloads the entire data set into an angular controller, and lets the information pulled from your waste input (key) turn out a bin location (and soon, addresses or places to take complex wastes such as hard drives, batteries, and lightbulbs) (value)
A list of Redis Commands can be found here.

This example website lists all events in plain format and renders LaTeX code. It lets the user choose a seminar series through a drop-down menu, and lists all the upcoming events for that series. It also has a dropdown menu which the user can use to see past semesters for the selected series.
Choose which series to display:


---
layout: archive_en
permalink: /metadata_en/
title: "Metadata of a Karuta element"
sidebar:
nav: "metadata_en"
---
Element metadata allow the designer to attribute unique identifiers to an element and also to
define it's behavior. For example, in the case of structural elements, we may define user-specific
menus that allow the designer or even an end-user to add additional elements inside this structural
element. In the case of resource elements, we may define the roles attributed to each right (who
can do what on each element). It is also in the metadata that we specify which elements will fill
a choice-box. Finally we may also specify which users will be able to share their portfolio with
other parties, and under which conditions.
Metadata is accessed through an element's editing box.
Some of the Karuta elements' metadata:
Semantic Tag
An element's Semantic Tag expresses it's semantics. It is also the means to search for an element
in a portfolio: the semantic tag is used in the Query field of an element (see Query below) as well
as in batch and report scripts.
Note: search of a semantic tag is inclusive — for example, the search for all elements with
semantic tag "competency" will also yield all elements with the semantic tag "sub-competency", as
the chain of characters of the first is included in the second.
Code
The Code of a portfolio element must be unique within this portfolio. It is used in choice boxes
(Get_Resource element, Get_Get_Resource element, Get_Muliple menu, Get_Get_Multiple menu and
Import_Multiple menu) to identify the end-user's selection.
By default, both the element's code and label are displayed in the choice box, and then only
the label of the user's selection is displayed in the Resource element. This behavior may be
modified by adding one or more of the following symbols to the element's code:
@
the code will not be displayed in the choice box
#
the code will be displayed in the Resource element
&
the associated value will be visible in the Resource element
(Item elements only)
%
the label will not be displayed in the Resource element
$
the label will not be displayed in the choice box
Multilingual Node
An element's Multilingual Node attribute specifies whether the element's Label is multilingual
(in the case of multilingual Karuta installations). If it is, two different labels can be specified
for the element (one in each language). If it is not, the element's label will be the same
independently of what language the portfolio is being viewed in (the value of the label will be
stored in the language defined as default language in the configuration file _init.js).
Note: the code is never multilingual. It has the same value independently of the selected viewing
language.
Multilingual Resource
An element's Multilingual Resource attribute specifies whether the data supplied for the element is
multilingual (in the case of multilingual Karuta installations). If it is, two different data sets
can be specified for the element (one in each language). If it is not, the element's data
will be the same independently of what language the portfolio is being viewed in (the data will be
stored in the language defined as default language in the configuration file _init.js).
Example: a person's name or birthdate is usually not language dependent (not multilingual) whereas
an essay or instructions are different in each language.
Encrypt Resource
This element attribute specifies whether the data in a Resource element is encrypted. If so,
a key phrase is requested from the user when they open the portfolio. This phrase is used to
encrypt and decrypt the data. It is not stored in the portfolio and thus must be memorized by
the end-user.
Roles - See
The list of user roles (separated by a space character) that may see the element. For example:
student teacher.
By default, this right is attributed to the role all. It is the only right to have a
default value.
Roles - Delete
The list of user roles (separated by a space character) that may delete the element.
Roles - Edit Resource
The list of user roles that may enter data in the element (only for Resource elements).
The list of user roles that may add a comment to the element. Comments are timestamped and signed
with the user name. A text editor is available to the users with the correct role for the purpose
of comment writing.
Note: The user role with the Comment right must also have the Edit Resource right on the element.
Roles - Submit
The list of user roles that may submit the element. Once submitted, the Edit Resource and Delete
rights are removed, for the element and all it's children. A submit button is available to
the users with the correct role for the purpose of submission.
Query
The Query field is used for:
- choice boxes (Get_Resource and Get_Get_Resource elements)
- custom menus on Sections, Pages and Subsections
- choice boxes allowing multiple user choices implemented through menus (Get_Multiple,
Get_Get_Multiple and Import_Multiple menus)
Format for Get_ (either Get_Resource or Get_Multiple)
portfolio_code
.semantic_tag
.label
-
portfolio_code
: Code of rubrics portfolio in which to search for the specified
semantic tag. Format is 'project code.rubrics portfolio code'. If 'project code.' is not present,
search for the rubrics portfolio will be in the current project (project containing the Get_).
semantic_tag
: Semantic tag of elements to search for in the rubrics portfolio.
label
: Reserved word.
Format Get_Get_ (either Get_Get_Resource or Get_Get_Multiple)
portfolio_code
.position

parent element in the rubrics portfolio).
semantic_tag2

Menu - Get_Multiple
This function allows the user to select multiple items from a list. For each item selected by the
user, an reusable component is added to the portfolio. This component is usualy a Get_Resource element,
but it may also be a structural element containing, amongst other things, the Get_Resource element. In
any case, the user's choice is set by Karuta in the Get_Resource element.

Chelsea salvages 4-4 draw after Ajax surrenders 3-goal lead
LONDON (AP) - Substitute Reece James completed an improbable comeback for Chelsea against Ajax in the Champions League on Tuesday as the host came from three goals down to draw 4-4 after the Dutch team was reduced to nine men.
Ajax was 4-1 up at Stamford Bridge after 55 minutes, but Chelsea pulled a goal back in the 63rd before Daley Blind and Joel Veltman were both sent off in a sequence that completely changed the game.
Chelsea was also awarded a penalty for handball by Veltman - which led to his second booking - and Jorginho made it 4-3 with his second spot kick of the game.
James equalized with a low show from a rebound in the 74th to complete the comeback, and Chelsea even thought it had scored a late winner through Cesar Azpilicueta. However, the goal was ruled out for a handball on Tammy Abraham after a video review.
Abraham’s own goal had given Ajax the lead before Jorginho equalized with his first penalty. Quincy Promes put Ajax in front with a header, while another own goal by Kepa Arrizabalaga and Donny van de Beek’s strike gave Ajax a three-goal lead.

Inserting Blank Lines into a File List
Selected from the Insert button menu in the file list dialog.
Selecting Blank line from the Insert menu inserts a single blank line into your file list at the current cursor position. This is a normal comment line; the only difference between this and inserting a Comment is that the description editor is not started after the line is inserted.

[gecode-users] List of pruned values
Guido Tack
tack at gecode.org
Fri Feb 3 09:07:48 CET 2012
Hi Matthew,
Gecode does not keep track of domain modifications on that level. The first thing I'd try is whether iterating through the variables is really too expensive. After all, checking whether the domain has changed is really cheap - just compare the domain sizes before and after (accessing them is constant time).
If iteration is prohibitively expensive, you have to implement a custom propagator that doesn't implement a constraint but simply "listens" to domain modifications. It would be posted for all variables you're interested in, create advisors to be notified of modifications (so that it doesn't have to iterate), and simply record that information in an external data structure. It doesn't ever have to be scheduled for propagation. Our tutorial documentation should contain all the information to get you started. Note that this approach also incurs an overhead, because each modification needs to be recorded somewhere, but that's just unavoidable.
Cheers,
Guido

Linux Command Line Shell Scripting
Shell Scripting
- Need for scripting
- Hello script
- Sourcing script
- Command Line Arguments
- Variables and Comparisons
- Accepting User Input interactively
- if then else
- for loop
- while loop
- Reading a file
- Debugging
- Real world use case
- Resource lists
Need for scripting
- Automate repetitive manual tasks
- Create specialized and custom commands
- Difference between scripting and programming languages
Note:
.sh
is typically used as extension for shell scripts- Material presented here is for
GNU bash, version 4.3.11(1)-release
Hello script
#!/bin/bash
# Print greeting message
echo "Hello $USER"
# Print day of week
echo "Today is $(date -u +%A)"
# use single quotes for literal strings
echo 'Have a nice day'
The first line has two parts
/bin/bash
is path ofbash
type bash
to get path
#!
called as shebang, directs the program loader to use the interpreter path provided
Comments
- Comments start with
#
- Comments can be placed at end of line of code as well
echo 'Hello' # end of code comment
- Multiline comments
Single quotes vs Double quotes
- Single quotes preserves the literal value of each character within the quotes
- Double quotes preserves the literal value of all characters within the quotes, with the exception of ‘$’, ‘`’, ‘', and, when history expansion is enabled, ‘!’
- Difference between single and double quotes
echo
builtin command
help -d echo
Write arguments to the standard output- By default,
echo
adds a newline and doesn’t interpret backslash -n
do not append a newline-e
enable interpretation of the following backslash escapes-E
explicitly suppress interpretation of backslash escapes- echo Q&A on unix stackexchange
$ chmod +x hello_script.sh
$ ./hello_world.sh
Hello learnbyexample
Today is Wednesday
Have a nice day
Sourcing script
$ help -d source
source - Execute commands from a file in the current shell.
- If script should be executed in current shell environment instead of sub-shell, use the
.
orsource
command- For example, after editing
~/.bashrc
one can usesource ~/.bashrc
for changes to be immeditely effective
- For example, after editing
$ # contents of prev_cmd.sh
prev=$(fc -ln -2 | sed 's/^[ \t]*//;q')
echo "$prev"
- For example, to access history of current interactive shell from within script
$ printf 'hi there\n'
hi there
$ bash prev_cmd.sh
$ printf 'hi there\n'
hi there
$ source prev_cmd.sh
printf 'hi there\n'
Command Line Arguments
#!/bin/bash
# Print line count of files given as command line argument
echo "No of lines in '$1' is $(wc -l < "$1")"
echo "No of lines in '$2' is $(wc -l < "$2")"
- Command line arguments are saved in positional variables starting with
$1 $2 $3
etc - If a particular argument requires multiple word string, enclose them in quotes or use appropriate escape sequences
$0
contains the name of the script itself - useful to code different behavior based on name of script used$@
array of all the command line arguments passed to script$#
Number of command line arguments passed to script- Use double quotes around variables when passing its value to another command
- bash special parameters reference
$ ./command_line_arguments.sh hello_script.sh test\ file.txt
No of lines in 'hello_script.sh' is 9
No of lines in 'test file.txt' is 5
Variables and Comparisons
dir_path=/home/guest
space has special meaning in bash, cannot be used around = in variablesgreeting='hello world'
use single quotes for literal stringsuser_greeting="hello $USER"
use double quotes for substitutionsecho $user_greeting
use$
when variable’s value is neededno_of_lines=$(wc -l < "$filename")
use double quotes around variables when passing its value to another commandnum=534
numbers can also be declared(( num = 534 ))
but using(( ))
for numbers makes life much easier(( num1 > num2 ))
number comparisons are also more readable within(( ))
[[ -e story.txt ]]
test if the file/directory exists[[ $str1 == $str2 ]]
for string comparisons

Accepting User Input interactively
#!/bin/bash
# Get user input
echo 'Hi there! This script returns the sum of two numbers'
read -p 'Enter two numbers separated by spaces: ' number1 number2
echo -e "\n$number1 + $number2 = $((number1 + number2))"
echo 'Thank you for using the script, Have a nice day :)'
help -d read
Read a line from the standard input and split it into fields-a
array assign the words read to sequential indices of the array variable ARRAY, starting at zero-p
prompt output the string PROMPT without a trailing newline before attempting to read-s
do not echo input coming from a terminal- More examples with read and getting input from stdin
$ ./user_input.sh
Hi there! This script returns the sum of two numbers
Enter two numbers separated by spaces: 7 42
7 + 42 = 49
Thank you for using the script, Have a nice day :)
if then else
#!/bin/bash
if (( $# != 2 ))
then
echo "Error!! Please provide two file names"
# simple convention for exit values is '0' for success and '1' for error
exit 1
else
# Use ; to combine multiple commands in same line
# -f option checks if file exists, ! negates the value
# white-space around [[ and ]] is necessary
if [[ ! -f $1 ]] ; then
echo "Error!! '$1' is not a valid filename" ; exit 1
else
echo "No of lines in '$1' is $(wc -l < "$1")"
fi
# Conditional Execution
[[ ! -f $2 ]] && echo "Error!! '$2' is not a valid filename" && exit 1
echo "No of lines in '$2' is $(wc -l < "$2")"
fi
- When handling user provided arguments, it is always advisable to check the sanity of arguments. A simple check can reduce hours of frustrating debug when things go wrong
- The code inside
if [[ ! -f $1 ]] ; then
block is only intended for demonstration, we could as well have used error handling ofwc
command if file doesn’t exist - Default
exit
value is0
, so need not be explicitly written for successful script completion - Use
elif
if you need to test more conditions afterif
- The operator
&&
is used to execute a command only when the preceding one successfully finishes - To redirect error message to stderr, use
echo "Error!! Please provide two file names" 1>&2
and so on -
[Control Operators && and ](http://mywiki.wooledge.org/BashGuide/TestsAndConditionals#Control_Operators_.28.26.26and.7C.7C.29) - More examples for if conditional block
$ ./if_then_else.sh
Error!! Please provide two file names
$ echo $?
1
$ ./if_then_else.sh hello_script.sh
Error!! Please provide two file names
$ echo $?
1
$ ./if_then_else.sh hello_script.sh xyz.tzt
No of lines in 'hello_script.sh' is 9
Error!! 'xyz.tzt' is not a valid filename
$ echo $?
1
$ ./if_then_else.sh hello_script.sh 'test file.txt'
No of lines in 'hello_script.sh' is 9
No of lines in 'test file.txt' is 5
$ echo $?
0
Combining if with exit status of command executed
Sometimes one needs to know if intended command operation was successful or not and then take action depending on outcome. Exit status of 0
is considered as successful condition when used with if
statement. When avaiable, use appropriate options to suppress stdout/stderr of command being used, otherwise redirection might be needed to avoid cluttering output on terminal
$ grep 'echo' hello_script.sh
echo "Hello $USER"
echo "Today is $(date -u +%A)"
echo 'Have a nice day'
$ # do not write anything to standard output
$ grep -q 'echo' hello_script.sh
$ echo $?
0
$ grep -q 'echo' xyz.txt
grep: xyz.txt: No such file or directory
$ echo $?
2
$ # Suppress error messages about nonexistent or unreadable files
$ grep -qs 'echo' xyz.txt
$ echo $?
2
Example
#!/bin/bash
if grep -q 'echo' hello_script.sh ; then
# do something
echo "string found"
else
# do something else
echo "string not found"
fi
for loop
#!/bin/bash
# Ensure atleast one argument is provided
(( $# == 0 )) && echo "Error!! Please provide atleast one file name" && exit 1
file_count=0
total_lines=0
# every iteration, variable file gets next positional argument
for file in "$@"
do
# Let wc show its error message if file doesn't exist
# terminate the script if wc command exit status is not 0
no_of_lines=$(wc -l < "$file") || exit 1
echo "No of lines in '$file' is $no_of_lines"
((file_count++))
((total_lines = total_lines + no_of_lines))
done
echo -e "\nTotal Number of files = $file_count"
echo "Total Number of lines = $total_lines"
- This form of
for
loop is useful if we need only element of an array, without having to iterate over length of an array and using an index for each iteration to get array elements - In this example we use the control operator
||
to stop the script ifwc
fails i.e ‘exit status’ other than0
$ ./for_loop.sh
Error!! Please provide atleast one file name
$ echo $?

Index based for loop
#!/bin/bash
# Print 0 to 4
for ((i = 0; i < 5; i++))
do
echo $i
done
Iterating over used defined array
$ files=('report.log' 'pass_list.txt')
$ for f in "${files[@]}"; do echo "$f"; done
report.log
pass_list.txt
Files specified by glob pattern
A common mistake is to use output of ls
command which is error prone and needless. Instead, the arguments can be directly used.
$ ls
pass_list.txt power.log report.txt
$ for f in power.log *.txt; do echo "$f"; done
power.log
pass_list.txt
report.txt
while loop
#!/bin/bash
# Print 5 to 1
(( i = 5 ))
while (( i != 0 ))
do
echo $i
((i--))
done
- Use
while
when you need to execute commands according to a specified condition
$ ./while_loop.sh
5

Reading a file
Reading line by line
#!/bin/bash
while IFS= read -r line; do
# do something with each line
echo "$line"
done < 'files.txt'
IFS
is used to specify field separator which is by default whitespace.IFS=
will clear the default value and prevent stripping of leading and trailing whitespace of lines- The
-r
option forread
will prevent interpreting\
escapes - Last line from input won’t be read if not properly terminated by newline character
$ cat files.txt
hello_script.sh
if_then_else.sh
$ ./while_read_file.sh
hello_script.sh
if_then_else.sh
Reading line as different fields
- By default, whitespace is delimiter
- Specify a different one by setting
IFS
$ cat read_file_field.sh
#!/bin/bash
while IFS=: read -r genre name; do
echo -e "$genre\t:: $name"
done < 'books.txt'
$ cat books.txt
fantasy:Harry Potter
sci-fi:The Martian
mystery:Sherlock Holmes
$ ./read_file_field.sh
fantasy :: Harry Potter
sci-fi :: The Martian
mystery :: Sherlock Holmes
Reading ‘n’ characters at a time
$ while read -n1 char; do echo "Character read is: $char"; done <<< "\word"
Character read is: w
Character read is: o
Character read is: r
Character read is: d
Character read is:
$ # if ending newline character is not desirable
$ while read -n1 char; do echo "Character read is: $char"; done < <(echo -n "hi")
Character read is: h
Character read is: i
$ while read -r -n2 chars; do echo "Characters read: $chars"; done <<< "\word"
Characters read: \w
Characters read: or
Characters read: d
Debugging
-x
Print commands and their arguments as they are executed-v
verbose option, print shell input lines as they are readset -xv
use this command to enable debugging from within script itself
$ bash -x hello_script.sh
+ echo 'Hello learnbyexample'
Hello learnbyexample
++ date -u +%A
+ echo 'Today is Friday'
Today is Friday
+ echo 'Have a nice day'
Have a nice day
$ bash -xv hello_script.sh
#!/bin/bash
# Print greeting message
echo "Hello $USER"
+ echo 'Hello learnbyexample'
Hello learnbyexample
# Print day of week
echo "Today is $(date -u +%A)"
date -u +%A
++ date -u +%A
+ echo 'Today is Friday'
Today is Friday
# use single quotes for literal strings
echo 'Have a nice day'
+ echo 'Have a nice day'
Have a nice day
Real world use case
With so much copy-paste of commands and their output involved in creating these chapters, mistakes do happen. So a script to check correctness comes in handy. Consider the below markdown file
## Some heading
Some explanation
```bash
$ seq 3
1
2
3
$ printf 'hi there!\n'
hi there!
```
## Another heading
More explanations
```bash
$ help -d readarray
readarray - Read lines from a file into an array variable.
$ a=5
$ printf "$a\n"
5
```
- The whole file is read into an array so that index of next line to be read can be controlled dynamically
- Once a command is identified to be tested
- the expected output is collected into a variable. Multiple lines are concatenated. Some commands do not have stdout to compare against
- accordingly the index of next iteration is corrected
- Note that this is a sample script to demonstrate use of shell script. It is not fool-proof, doesn’t have proactive check for possible errors, etc
- Be sure
eval
is being used for known commands like is the case here - See Parameter Expansion for examples and explanations on string processing constructs
#!/bin/bash
cb_start=0
readarray -t lines < 'sample.md'
for ((i = 0; i < ${#lines[@]}; i++)); do
# mark start/end of command block
# Line starting with $ to be verified only between ```bash and ``` block end
[[ ${lines[$i]:0:7} == '```bash' ]] && ((cb_start=1)) && continue
[[ ${lines[$i]:0:3} == '```' ]] && ((cb_start=0)) && continue
if [[ $cb_start == 1 && ${lines[$i]:0:2} == '$ ' ]]; then
cmd="${lines[$i]:2}"
# collect command output lines until line starting with $ or ``` block end
cmp_str=''
j=1
while [[ ${lines[$i+$j]:0:2} != '$ ' && ${lines[$i+$j]:0:3} != '```' ]]; do
cmp_str+="${lines[$i+$j]}"
((j++))
done
((i+=j-1))
cmd_op=$(eval "$cmd")
if [[ "${cmd_op//$'\n'}" == "${cmp_str//$'\n'}" ]]; then
echo "Pass: $cmd"
else
echo "Fail: $cmd"
fi
fi
done
- Note how sourcing the script is helpful to take into consideration commands dependent on previous commands
$ ./verify_cmds.sh
Pass: seq 3
Pass: printf 'hi there!\n'
Pass: help -d readarray
Pass: a=5
Fail: printf "$a\n"
$ source verify_cmds.sh
Pass: seq 3
Pass: printf 'hi there!\n'
Pass: help -d readarray
Pass: a=5
Pass: printf "$a\n"

This is a backend to publish geospatial Data Packages- an application that allows us to connect and manage spatial information, then configure and export it to the frontend applications through an API based on the Frictionless Data standard.
Projects can be accessed and their models and viewed by clicking on the SmartUse logo on the home page. This is for the time beingi the primary navigation between projects. There is also a link on the home page to an online API platform for developers. The frontend is built on this basis, and other apps could also connect to SmartUse with the API. The Web API can be used to access data about Projects.
This project is developed and supported by SmartUse GmbH.
FrontendThe following instructions detail how to manage your data publication in the Smart Use backend.
The following data formats are currently supported:
Data files for any of the formats above can be uploaded in the Data tab, and then linked with the path
. For example, if you uploaded a GeoJSON file called pendlerorte.geojson
into a test_project/data folder, you could just enter /uploads/test_project/data/pendlerorte.geojson
. Just click on the file listing to visit the location at the appropriate URL.

This is an example showing the cookie bar's default settings.
Ensure you have jQuery, jQuery CookieBar and jQuery CookieBar's CSS uploaded to your website and linked in the header of your website
<link rel="stylesheet" type="text/css" href="/css-folder/jquery.cookiebar.css" />
<script type="text/javascript" src="/scripts-folder/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="/scripts-folder/jquery.cookiebar.js"></script>
Make sure you then include the following line of code within $(document).ready():
$.cookieBar();
If you find that the bar appears even after accepting/declining, make sure "forceShow" is set to false.
