public abstract class Preferences extends Object
There are two separate trees of preference nodes, one for user preferences and one for system preferences. Each user has a separate user preference tree, and all users in a given system share the same system preference tree. The precise description of "user" and "system" will vary from implementation to implementation. Typical information stored in the user preference tree might include font choice, color choice, or preferred window location and size for a particular application. Typical information stored in the system preference tree might include installation configuration data for an application.
Nodes in a preference tree are named in a similar fashion to directories in a hierarchical file system. Every node in a preference tree has a node name (which is not necessarily unique), a unique absolute path name, and a path name relative to each ancestor including itself.
The root node has a node name of the empty string (""). Every other node has an arbitrary node name, specified at the time it is created. The only restrictions on this name are that it cannot be the empty string, and it cannot contain the slash character ('/').
The root node has an absolute path name of "/". Children of the root node have absolute path names of "/" + <node name>. All other nodes have absolute path names of <parent's absolute path name> + "/" + <node name>. Note that all absolute path names begin with the slash character.
A node n's path name relative to its ancestor a is simply the string that must be appended to a's absolute path name in order to form n's absolute path name, with the initial slash character (if present) removed. Note that:
Note finally that:
All of the methods that modify preferences data are permitted to operate asynchronously; they may return immediately, and changes will eventually propagate to the persistent backing store with an implementation-dependent delay. The flush method may be used to synchronously force updates to the backing store. Normal termination of the Java Virtual Machine will not result in the loss of pending updates -- an explicit flush invocation is not required upon termination to ensure that pending updates are made persistent.
All of the methods that read preferences from a Preferences
object require the invoker to provide a default value. The default value is
returned if no value has been previously set or if the backing store is
unavailable. The intent is to allow applications to operate, albeit
with slightly degraded functionality, even if the backing store becomes
unavailable. Several methods, like flush, have semantics that
prevent them from operating if the backing store is unavailable. Ordinary
applications should have no need to invoke any of these methods, which can
be identified by the fact that they are declared to throw BackingStoreException
.
The methods in this class may be invoked concurrently by multiple threads in a single JVM without the need for external synchronization, and the results will be equivalent to some serial execution. If this class is used concurrently by multiple JVMs that store their preference data in the same backing store, the data store will not be corrupted, but no other guarantees are made concerning the consistency of the preference data.
This class contains an export/import facility, allowing preferences to be "exported" to an XML document, and XML documents representing preferences to be "imported" back into the system. This facility may be used to back up all or part of a preference tree, and subsequently restore from the backup.
The XML document has the following DOCTYPE declaration:
<!DOCTYPE preferences SYSTEM "http://java.sun.com/dtd/preferences.dtd">
Note that the system URI (http://java.sun.com/dtd/preferences.dtd) is
not accessed when exporting or importing preferences; it merely
serves as a string to uniquely identify the DTD, which is:
<?xml version="1.0" encoding="UTF-8"?>
<!-- DTD for a Preferences tree. -->
<!-- The preferences element is at the root of an XML document
representing a Preferences tree. -->
<!ELEMENT preferences (root)>
<!-- The preferences element contains an optional version attribute,
which specifies version of DTD. -->
<!ATTLIST preferences EXTERNAL_XML_VERSION CDATA "0.0" >
<!-- The root element has a map representing the root's preferences
(if any), and one node for each child of the root (if any). -->
<!ELEMENT root (map, node*) >
<!-- Additionally, the root contains a type attribute, which
specifies whether it's the system or user root. -->
<!ATTLIST root
type (system|user) #REQUIRED >
<!-- Each node has a map representing its preferences (if any),
and one node for each child (if any). -->
<!ELEMENT node (map, node*) >
<!-- Additionally, each node has a name attribute -->
<!ATTLIST node
name CDATA #REQUIRED >
<!-- A map represents the preferences stored at a node (if any). -->
<!ELEMENT map (entry*) >
<!-- An entry represents a single preference, which is simply
a key-value pair. -->
<!ELEMENT entry EMPTY >
<!ATTLIST entry
key CDATA #REQUIRED
value CDATA #REQUIRED >
Every Preferences implementation must have an associated PreferencesFactory
implementation. Every Java(TM) SE implementation must provide
some means of specifying which PreferencesFactory implementation
is used to generate the root preferences nodes. This allows the
administrator to replace the default preferences implementation with an
alternative implementation.
Implementation note: In Sun's JRE, the PreferencesFactory implementation is located as follows:
If the system property java.util.prefs.PreferencesFactory is defined, then it is taken to be the fully-qualified name of a class implementing the PreferencesFactory interface. The class is loaded and instantiated; if this process fails then an unspecified error is thrown.
If a PreferencesFactory implementation class file
has been installed in a jar file that is visible to the
system class loader
,
and that jar file contains a provider-configuration file named
java.util.prefs.PreferencesFactory in the resource
directory META-INF/services, then the first class name
specified in that file is taken. If more than one such jar file is
provided, the first one found will be used. The class is loaded
and instantiated; if this process fails then an unspecified error
is thrown.
Finally, if neither the above-mentioned system property nor an extension jar file is provided, then the system-wide default PreferencesFactory implementation for the underlying platform is loaded and instantiated.

This convention does not apply to the unnamed package, whose associated preference node is <unnamed>. This node is not intended for long term use, but for convenience in the early development of programs that do not yet belong to a package, and for "throwaway" programs. Valuable data should not be stored at this node as it is shared by all programs that use it.
A class Foo wishing to access preferences pertaining to its package can obtain a preference node as follows:
static Preferences prefs = Preferences.userNodeForPackage(Foo.class);This idiom obviates the need for using a string to describe the preferences node and decreases the likelihood of a run-time failure. (If the class name is misspelled, it will typically result in a compile-time error.)

Implementations are free to flush changes into the persistent store at any time. They do not need to wait for this method to be called.
When a flush occurs on a newly created node, it is made persistent, as are any ancestors (and descendants) that have yet to be made persistent. Note however that any preference value changes in ancestors are not guaranteed to be made persistent.
If this method is invoked on a node that has been removed with

Events are only guaranteed for changes made within the same JVM as the registered listener, though some implementations may generate events for changes made outside this JVM. Events may be generated before the changes have become permanent. Events are not generated when indirect descendants of this node are added or removed; a caller desiring such events must register with each descendant.
Few guarantees can be made regarding node creation. Because nodes are created implicitly upon access, it may not be feasible for an implementation to determine whether a child node existed in the backing store prior to access (for example, because the backing store is unreachable or cached information is out of date). Under these circumstances, implementations are neither required to generate node change events nor prohibited from doing so.

We are building a library of formal representations of common actions, entities, and modifiers to enable building knowledge bases efficiently. The components are implemented in KM, our language for knowledge representation and automated reasoning. Both the Component Library and KM are protected by copyright, but are distributed under the Simplified BSD License.
Most components have (or will have!) two descriptions:
Both the specifications and the axioms use a set of relations that are defined in our slot dictionary.
The KM axioms for most components include "test-cases". These test cases are executed every day to ensure that errors have not crept into the component library.
Building the Component Library is a long-term project, and we've only just begun. So, please visit us again to see what's new. If you would like to use the Component Library, or contribute to it (!), please contact Bruce Porter.

Hand, foot and mouth disease
Hand, foot and mouth disease is a common infection that mostly affects children under 10.
Hand, foot and mouth disease usually clears up by itself, within about a week.
Check if you have hand, foot and mouth disease
The first sign of hand, foot and mouth disease can be:
- a sore throat
- a fever, typically 38-39C
- loss of appetite
It may be a few days before the ulcers and rash appear.
If you’re unsure it’s hand, foot and mouth disease, look at other childhood rashes
Things you can do at home to ease the symptoms
- drink fluids to avoid dehydration (avoid acidic drinks, like fruit juice)
- eat soft foods like soup
- take paracetamol or ibuprofen can help ease a sore throat and bring down a temperature
Mouth ulcer gels, sprays, and mouthwashes, might ease the blisters
When you buy medicines, always check they are suitable for children and give the correct dose.
When to see your GP
Speak to your GP if:
- your child isn’t better after a week
- your child is dehydrated – they’re not weeing as often as usual
- you’re concerned about your child’s symptoms
- you’re pregnant and develop hand, foot and mouth disease
Hand, foot and mouth disease spreads easily
It’s best to avoid close contact with anyone with hand, foot and mouth disease.
Individual schools and nurseries may have their own guidance for when your child can return so it’s best to check with them.
Generally, keep them away from school or nursery while they are feeling unwell. There’s no need to keep them off until the blisters have healed.
Hand, foot and mouth disease in pregnancy
There’s normally no risk to the pregnancy or baby.
However, it’s best to avoid close contact with anyone who has hand, foot and mouth disease.
There’s limited evidence that in very rare cases catching hand, foot and mouth disease during the first three months of pregnancy could lead to miscarriage – due to the fever. However, this risk is very low.

Hey there! I'm Emilie and I'm a designer eager to make a difference in the world. I am very interested in how we can combine technology, creativity, and empathy to create seamless and meaningful experiences for others. Born in Oakland, CA and raised in San Leandro, CA ✌ I built my foundation of UX design knowledge at UC San Diego in the Cognitive Science // Human-Computer Interaction program, and grew my abilities to apply this knowledge during my time in the Integrated Digital Media Master's program at New York University. I now focus on improving the digital experience of offerings in the Hybrid Cloud organization at IBM, as a UX Designer.
In my free time, I love to letter, run (once in a while), and discover new music. I run a lettering Instagram that I update on a very irregular basis 😅.

What to Bring
Watch the weather closely. The show goes on no matter what the weather is doing.
You must wear your chip timing piece during the entire event. You will be given a band that will hold
your chip timing piece
around your ankle throughout the entire event.
Be sure that it is snapped tightly.
Be sure to have your Chip Timing piece on
before you start the race and be sure to step over the timing mats after each segment of the
race.
If you are wearing a wet-suit, make sure the timing piece goes under your wetsuit otherwise, you will
have a very difficult time getting off your
wet suit.
Swim:
Wetsuits are optional for the swim but will provide buoyancy and warmth. However, many people opt for no wetsuit for a triathlon so no worries. We will provide you with a swim cap but you will want to bring your own goggles.
Bike:
A biking helmet is mandatory. You will also receive 2 stickers in your package with your race number on
them.  The bigger sticker will wrap around your
bike frame.
Road or mountain bikes are acceptable. For safety reasons, be sure to have end-caps
on the
end of your handle-bars.
 Some people choose to pin it on at the
beginning of the race and have it on for the whole event so they don't have to worry about it.
Others pin it on a singlet that they put on once they finish the swim before they head out for
the bike.
Others use an elastic racing strap that they pin their bib number to
and then quickly strap it on before they leave for the run. Use whatever option feels best for you.

There is not touch prerequisites for learning JavaScript. Here are some of the prerequisite for learning JavaScript:
Basic programming knowledge. Knowledge of core Java sufficient.
You should have knowledge of HTML. Check HTML tutorials here.
Why it is worth learning React Modularity?
import
and export
support our ability to build modular codeReact is a JavaScript library (not a framework) that creates user interfaces (UIs) in a predictable and efficient way using declarative code. You can use it to help build single page applications and mobile apps, or to build complex apps if you utilise it with other libraries. React works in declarative code. For more reference
Modular code is code that is separated into segments (modules), where each file is responsible for a feature or specific functionality.
Developers separate their code into modules for many reasons:
function Welcome(props) {
return
Hello, {props.name}
;
}
const element = <Welcome name="Faisal Arkan" />;
ReactDOM.render(
element,
document.getElementById('root')
);
name="Faisal Arkan"
will give value into {props.name}
from function Welcome(props)
and returning a component that has given value by name="Faisal Arkan"
. After that React will render the element into html.
class Cat extends React.Component {
constructor(props) {
super(props);
this.state = {
humor: 'happy'
}
}
render() {
return(

{this.props.name}

{this.props.color}

);
}
}
const Cat = props => {
return (

{props.name}

{props.color}

;
);
};
class Hogwarts extends React.Component {
render() {
return (

"Harry. Did you put your name in the Goblet of Fire?"

);
}
}
It’s standard practice to give each of these components their own file. It is not uncommon to see a React program file tree that looks something like this:
├── README.md
├── public
└── src
├── App.js
├── Hogwarts.js
└── Houses.js
For example:
// src/houses/HagridsHouse.js
import React from 'react';
function whoseHouse() {
console.log(`HAGRID'S HOUSE!`);
}
export default whoseHouse;

Mask and image with a LabelMap .
LabelMapMaskImageFilter mask the content of an input image according to the content of the input LabelMap . The masked pixel of the input image are set to the BackgroundValue. LabelMapMaskImageFilter can keep the input image for one label only, with Negated = false (the default) or it can mask the input image for a single label, when Negated equals true. In Both cases, the label is set with SetLabel() .

--- layout: post title: Avant Rural date: 2006-05-02 00:00:00 categories: amusing personal ---
I want to go to this: AvantRural. Found a flyer for it in my pocket this morning as I walked into work - I think someone pressed it into my sweaty palm as I wandered down the North Laine on Saturday.
Dress code: "wellington boots and dressing gowns appreciated but not required". The flyer promises "bovine modulation" and "badgercore"... brought to you by (amongst others) "the early gurning centre".
But "badgercore".
Say it again.
"badgercore"
