An abstract datatype for specifying a text font.
Available fonts vary by platform and device. On iOS, font support depends on the OS version. On Android, font support depends on the OS version and device manufacturer.
Note that to update the font used by a UI component, you must set the object's font
property, like this:
myLabel.font = { fontSize: 24, font: myFontName }
Changing the font
object after assigning it does not reliably affect the underlying UI
component:
// This may not work as expected
myLabel.font.fontSize = 24;
Custom TrueType (.ttf) or OpenType (.otf) fonts may be embedded in an application on iOS and Android. (Note that you must have redistribution rights on the fonts you ship.)
Custom fonts must be placed in the Resources/fonts
directory. Note that the steps
for referring to the fonts are slightly different by platform.
On Android, use the font file name, minus the .otf
or .ttf
extension.
For example, if you are using the Chantelli Antiqua font and the file is
named Chantelli_Antiqua.ttf
, specify fontFamily: 'Chantelli_Antiqua'
on Android.
On iOS, use the official font name--this name is embedded in the font file and
does not change if you rename the file. For example, for Chantelli Antiqua,
you'd specify: fontFamily: 'Chantelli Antiqua'
(with a space).
On OS X, double-clicking on the font file will launch the Font Book application,
which shows the official font name.
iOS requires one more step to embed a custom font in an application. The font must be
added to the application's Info.plist
file:
Build the project at least once (the font won't work yet).
Copy yourproject/build/iphone/Info.plist
to the yourproject folder.
Double-click Info.plist
to open it in Xcode.
Right-click a blank area in the list of keys and choose Add Row.
From the resulting list, choose Fonts provided by application.
Expand Fonts provided by application and click in the Value field.
Enter the full path of the font file, for example, /fonts/Chantelli_Antiqua.ttf
.
Save the file and close Xcode.
In Studio, clean the project then build it again. Your custom font should show up.
For more information on embedding custom fonts, see:
| Name | Type | Summary |
|---|---|---|
| fontFamily | String | Name of a font family, for example, "Helvetica" or "DroidSans". |
| fontSize | Number String | Font size, in platform-dependent units. |
| fontStyle | String | Font style. Valid values are "italic" or "normal". |
| fontWeight | String | Font weight. Valid values are "bold" or "normal". |


The top section of this page allows you to define named classes, based on user types and source addresses. Every login is classified into the first matching class, so classes should be ordered from the most to least specific. The matching addresses for each class can be full or partial IP addresses, IP networks/netmasks, hostnames, host wildcards (like *.foo.com) or the absolute paths to files containing additional addresses. Any type of address can be preceded with a ! to negate it.
The middle section of this page allows you to control which Unix users to classify as guests. A guest user has similar rights to a normal Unix user, but is restricted to a certain directory using chroot.
The lower section of the page controls which Unix and guest users will be denied access to the FTP server. You may specify users by name, by GID (like %3000) or by GID range (like %3000-3010).

'use strict';
const fs = require('fs');
const tape = require('tape');
const util = require('util');
In this blog post, we write a minimal SAT solver.
A SAT solver determines whether a boolean formula can be “satisfied” (made true) by an appropriate assignment of true
and false
to the variables constituting that formula.
For example, the boolean formula
(x1 ⇒ x2) ∧ (x1 ∨ ∼x3)
corresponds with the equation
true ≡ (x1 ⇒ x2) ∧ (x1 ∨ ∼x3)
which could be satisfied with the assignments
(x1 ≡ false) ∧ (x2 ≡ true) ∧ (x3 ≡ false)
Note that while the SAT problem concerns itself only with the existence of such an assignment, when such an assignment does exist, our solver will emit it. This provides a way to easily validate our code, as an assignment can be verified in polynomial time.
'use strict';
const fs = require('fs');
const tape = require('tape');
const util = require('util');
Let’s start by writing a test to outline what “correct” looks like.
We introduce a function that lets us embed tests in this source file, choosing to run the tests by passing a --self-test
command line argument.
For the underlying tests, we leverage the tape library, which outputs test results in the Test Anything Protocol (TAP) format.
function testfn(fn, testImpl) {
if (process.argv.includes('--self-test')) {
tape(fn.name, t => testImpl(t, fn));
}
}
Every boolean formula can be expressed as a a conjunction of disjunctions (AKA conjunctive normal form, or CNF) , and by constraining our solver to input in that form, we can avoid tokenizing, parsing (which includes handling operator precedence), and writing logic for redundant operators like logical implication.
For example, the initial example
(x1 ⇒ x2) ∧ (x1 ∨ ∼x3)
could be converted to CNF as
(∼ x1 ∨ x2) ∧ (x1 ∨ ∼x3)
which would be encoded as
[{x1: false, x2: true}, // clause 1
{x1: true, x3: false}] // clause 2
So our SAT solver solve
accepts an array of clauses, where every clause must be satisfied, and to satisfy a clause at least one of the literals must match the associated value. With this in mind, we can implement our primary test.
testfn(solve, (t, fn) => {
const unsatisfiable = [
[{a: true}, {a: false}],
[{a: true, b: false}, {b: true}, {a: false}],
];
for (const problem of unsatisfiable) {
const assignment = fn(problem);
t.deepEqual(assignment, null);
}
const satisfiable = [
[{a: false}],
[{a: true}],
[{a: true, b: true}, {b: true}],
[{a: true, b: true}, {b: false}],
[{a: true, b: true}, {a: false, b: false}],
[{a: true, b: true, c: false}, {a: false, b: false}, {b: true, c: false}],
[{a: true, b: true, c: false}, {a: false, b: false}, {b: true, c: true}],
[{a: true, b: false, c: false}, {a: false, b: false}, {b: true, c: true}],
[{a: true, b: true}, {b: true, c: true}],
[{a: false, b: true}, {b: false}, {c: false, b: true}],
];
for (const problem of satisfiable) {
const assignment = fn(problem);
t.ok(!!assignment);
const isValidAssignment = problem.every(clause => {
const isSatisfied = Object.keys(clause).some(atom => clause[atom] === assignment[atom]);
return isSatisfied;
});
t.ok(isValidAssignment);
}
t.end();
});
Many SAT algorithms exist, and one of the most fundamental is DPLL. We collect assignments as follows:
true
and false
, we backtrack (as a different assignment of previously assigned variables might be successful).
function solve(clauses, assignment = {}) {
return trace(solve, arguments, () => { // we wrap in a helper for debugging
const v = nextVar(clauses);
if (!v) { return assignment; }
for (const value of [true, false]) {
if (canAssign(value, v, clauses)) {
const result = solve(removeVar(value, v, clauses), newAssignment(assignment, v, value));
if (result) { return result; }
}
}
return null;
});
}
The above implementation relies on the following four helpers:
nextVar
: choose a variable favoring “unit” clauses with only one possible assignment;canAssign
: infer when an assignment of that variable violates any clause;removeVar
: “clean up” satisfied clauses; andnewAssignment
: add a variable-to-truth-value assignment to a collection of assignments.
testfn(nextVar, (t, fn) => {
t.deepEqual(fn([]), null);
t.deepEqual(fn([{}]), null);
t.deepEqual(fn([{x: 0}]), 'x');
t.deepEqual(fn([{x: 0, y: 0}]), 'x');
t.end();
});
function nextVar(clauses) {
const clauseKeys = clauses.map(c => Object.keys(c));
if (clauseKeys.some(c => c.length == 0)) {
return null;
}
const unit = clauseKeys.find(c => c.length == 1);
if (unit) {
return unit[0];
}
return clauseKeys.reduce((l, r) => l.concat(r), []).find(x => x) || null;
}
testfn(canAssign, (t, fn) => {
t.deepEqual(fn(true, 'x', []), true);
t.deepEqual(fn(true, 'x', [{}]), true); // NOTE: clause is unsat, but assignment is valid
t.deepEqual(fn(true, 'x', [{y: true}]), true);
t.deepEqual(fn(true, 'x', [{y: false}]), true);
t.deepEqual(fn(true, 'x', [{x: true}]), true);
t.deepEqual(fn(true, 'x', [{x: false}]), false);
t.end();
});
function canAssign(value, variable, clauses) {
return clauses.every(c => Object.keys(c).length > 1 || !c.hasOwnProperty(variable) || c[variable] == value);
}
testfn(removeVar, (t, fn) => {
t.deepEqual(
fn(true, 1, [{1: false, 3: true}, {2: false}, {2: true, 3: false}]),
[{3: true}, {2: false}, {2: true, 3: false}]);
t.deepEqual(
fn(false, 1, [{1: false, 3: true}, {2: false}, {2: true, 3: false}]),
[{2: false}, {2: true, 3: false}]);
t.end();
});
function removeVar(value, variable, clauses) {
return clauses.filter(c => c[variable] !== value).map(c => {
const result = Object.assign({}, c);
delete result[variable];
return result;
});
}
testfn(newAssignment, (t, fn) => {
t.deepEqual(
newAssignment({}, 'x', true),
{x: true});
t.deepEqual(
newAssignment({}, 'y', false),
{y: false});
t.deepEqual(
newAssignment({x: false}, 'y', true),
{x: false, y: true});
t.end();
});
function newAssignment(original, variable, value) {
const result = Object.assign({}, original);
result[variable] = value;
return result;
}
The DIMACS CNF format specifies a common encoding for CNF expressions. By parsing this format, we can validate our implemenation against more test data and also easily compare our SAT performance with other implementations.
testfn(parseDimacs, (t, fn) => {
const example = `
c simple_v3_c2.cnf
c
p cnf 3 2
1 -3 0
2 3 -1 0
`;
t.deepEqual(
parseDimacs(example),
[{x1: true, x3: false}, {x1: false, x2: true, x3: true}]);
t.end();
});
function parseDimacs(data) {
First we remove comments, which are lines starting with a “c” character.
data = data.replace(/(^|\n)c.*/g, '');
Next we extract the problem description, which indicates the number of symbols and clauses. For simplicity, we just throw this away as we can infer it from the rest of the file.
const lines = data.replace(/(^|\n)c.*/g, '').split('\n');
let i = 0;
while (lines[i].length == 0 || lines[i][0] != 'p') { ++i; }
const problem = lines[i].match(/\S+/g);
debug({problem});
Now we are ready to extract the clauses. Note that clauses are “0” delimited, not newline delimited.
const clauses = lines.splice(i+1) // start w/ lines after the problem
.join('\n').split(/\s+0/) // split on '0' character delimiter instead of newline
.map(l => l.match(/\S+/g)) // extract tokens
.filter(l => l); // and filter out noise
debug({clauses});
The clauses are encoded such that -num
indicates that xnum is false while num
indicates xnum is true.
return clauses.map(encoded => {
const decoded = {};
for (const sym of encoded) {
if (sym < 0) {
decoded['x' + -sym] = false;
} else {
decoded['x' + sym] = true;
}
}
return decoded;
});
}
Similar to our testfn
helper, we introduce a timefn
helper that only runs performance tests if the program is started with a --perf
argument.
function timefn(fn, impl) {
const count = 1;
if (!process.argv.includes('--perf')) { return; }
console.log(`# ${fn.name}`);
impl(fn, (description, computation) => {
const start = new Date();
for (let i = 0; i < count; ++i) {
computation();
}
const end = new Date();
console.log(`## ${description}: ${(end - start)/count} ms`);
});
}
To stress our solver a bit, we have three example DIMACS CNF files:
timefn(solve, (fn, time) => {
fs.readFile('aim-50-1_6-yes1-4.cnf', 'utf-8', (err, data) => {
const constraints = parseDimacs(data);
time('aim-50-1_6-yes1-4.cnf: satisfiable', () => solve(constraints));
});
fs.readFile('aim-100-1_6-no-1.cnf', 'utf-8', (err, data) => {
const constraints = parseDimacs(data);
time('aim-100-1_6-no-1.cnf: unsatisfiable', () => solve(constraints));
});
fs.readFile('zebra_v155_c1135.cnf', 'utf-8', (err, data) => {
const constraints = parseDimacs(data);
time('zebra_v155_c1135.cnf: satisfiable', () => solve(constraints));
});
});
Two of the problems are satisfiable and take just under a second on my laptop, while one is unsatisfiable and takes just over a minute on the same hardware. For comparison, the industrial strength Z3 theorem prover can solve all three in milliseconds. It’s clear that this minimal example has lots of room for performance improvements!
TAP parsers expect a leading #
for comments, and outputing debug information to the console without that leading #
breaks parsing.
To make our debug logging slightly less verbose, we introduce another small helper, debug
.
Note that while #
indicates a comment, nodejs TAP reporters (such as tap-spec) typically interpret #
as a test name, so this helper emits a ##
, which most parsers interpret as a non-test-comment.
function debug(format, ... other) {
if (process.argv.includes('--debug')) {
if (typeof format != 'string') {
format = util.inspect(format);
}
console.log('## ' + format, ...other);
}
}
It’s also useful to be able to trace function calls, so we introduce a helper for that as well. Example output:
## solve <-- [ { a: true, b: true }, { b: true } ]
## solve <-- [ { b: true } ], { a: true }
## solve <-- [], { a: true, b: true }
## solve --> { a: true, b: true }
## solve --> { a: true, b: true }
## solve --> { a: true, b: true }
function trace(fn, args, impl) {
if (!process.argv.includes('--debug')) { return impl.apply(this, args); }
trace.depth = trace.depth || 0;
const pad = ' '.repeat(trace.depth);
const name = fn.name || new Error().stack.match(/ at ([^ ]+)/g)[1].split(' ')[2];
try {
++trace.depth;
debug(`${pad}${name} <--`, Array.from(args).map(util.inspect).join(', '));
const result = impl.apply(this, args);
debug(`${pad}${name} -->`, result);
return result;
} catch(err) {
debug(`${pad}${name} !!!`, err);
throw err;
} finally {
--trace.depth;
}
}

Hydra is a lightweight vocabulary to create hypermedia-driven Web APIs. By specifying a number of concepts commonly used in Web APIs it enables the creation of generic API clients.
This entire document is a work in progress and several sections are incomplete, missing, or outdated. All open issues and decisions are documented in our issue tracker. If you have questions, please don't hesitate to join the Hydra W3C Community Group and post to the mailing list.
This specification was published by the Hydra W3C Community Group. It is not a W3C Standard nor is it on the W3C Standards Track. Please note that under the W3C Community Contributor License Agreement (CLA) there is a limited opt-out and other conditions apply. Learn more about W3C Community and Business Groups.

Coping with the ever-increasing amount of data becomes increasingly challenging. To alleviate the information overload put on people, systems are progressively being connected directly to each other. They exchange, analyze, and manipulate humongous amounts of data without any human interaction. Most current solutions, however, do not exploit the whole potential of the architecture of the World Wide Web and completely ignore the possibilities offered by Linked Data technologies.
The combination of the REST architectural style and the Linked Data principles offer opportunities to advance the Web of machines in a similar way that hypertext did for the human Web. Most building blocks exist already and are in place but they are rarely used together. Hydra tries to fill that gap. It allows data to be enriched with machine-readable affordances which enable interaction. This not only addresses the problem that Linked Data is still mostly read-only, but it also paves the way for a completely new breed of interoperable Web APIs. The fact that it enables the creation of composable contracts means that interaction models of Web APIs can be reused at an unprecedented granularity.
This specification describes the conformance criteria for Hydra API documentations and Hydra clients. This criteria is relevant to authors, authoring tool implementers, and client implementers. All authoring guidelines, diagrams, examples, and notes in this specification are non-normative, as are all sections explicitly marked as non-normative. Everything else in this specification is normative.
Conformance for Hydra clients should probably not be specified in this document.
Add normative statements
The key words MUST, MUST NOT, REQUIRED, SHALL, SHALL NOT, SHOULD, SHOULD NOT, RECOMMENDED, NOT RECOMMENDED, MAY, and OPTIONAL in this specification have the meaning defined in [[!RFC2119]].
The basic idea behind Hydra is to provide a vocabulary which enables a server to advertise valid state transitions to a client. A client can then use this information to construct HTTP requests which modify the server’s state so that a certain desired goal is achieved. Since all the information about the valid state transitions is exchanged in a machine-processable way at runtime instead of being hardcoded into the client at design time, clients can be decoupled from the server and adapt to changes more easily.
The figure below illustrates the Hydra core vocabulary (the figure’s intention is to show how Hydra is used rather than its precise definition).
Is this illustration clear enough or is it confusing? Feedback would be much appreciated.
Add ranges for Operation "members"
An alphabetical index of the classes and properties of Hydra is given below. All the terms are hyperlinked to their detailed description for quick reference.
The used prefixes should be documented somewhere.
Throughout this section, a simple Web API featuring an issue tracker will be used to illustrate how Hydra can be used. The Web API enables its users to file new issues, modify or delete existing ones, and to comment them. For the sake of simplicity, orthogonal aspects such as authentication or authorization are not covered.
The exemplary Web API has to expose representations of issues and comments. To enable interaction with those resources, a client has to know which operations the server supports. In human-facing websites such affordances are typically exposed by links and forms and described in natural language. Unfortunately, machines can not interpret such information easily. The solution that presents itself is to reduce the language to a small number of unambiguous concepts which are easily recognizable by a machine client. Hydra formalizes such concepts.
The simplest and most important affordance on the Web are hyperlinks. Without them, it would be impossible to browse the Web. Users typically select the link based on the text it is labeled with. To give machines a similar understanding, links can be annotated with a link relation type—a registered token or a URI identifying the semantics of the link. The following example shows how such a typed link is used in HTML to reference a stylesheet.
In Linked Data, the link relation type corresponds to the property itself. An example in JSON-LD would thus look as follows.
Generally, a client decides whether to follow a link or not based on
the link relation (or the property in general, in the case of
Linked Data) which defines its semantics. There are however also
clients such as Web crawlers which simply follow every which is
intended to be dereferenced. In HTML this usually means that all
links in anchor elements (the <a>
tag) are
followed but, e.g., most references in link elements (the
<link>
tag), such as used in the example above,
are ignored. Since in RDF serializations no such distinction exists,
the best a client can do is to blindly try to dereference all URIs.
It would thus be beneficial to describe in a machine-readable manner
whether a property represents a link that is intended to be
dereferenced or whether it solely represents an identifier. Hydra's
Link class does just that. It can be used to define properties
that represent dereferenceable links. In the exemplary Web API used
throughout this section, it can, e.g., be used to define a property
linking issues to their comments:
In the example above, a property identified with the URL
http://api.example.com/vocab#comments
is defined to be
of the type Link. This is enough information for a client
understanding Hydra to know that the value of the
comments
property in the following example is intended
to be dereferenced.
In the example above, the value of the comments
property is a JSON object with an @id
member. This is
JSON-LD's convention to distinguish between strings and IRIs. By
using JSON-LD's type-coercion feature, the representation can be
made even more idiomatic:
While links are enough to build read-only Web APIs, more powerful affordances are required to build read-write Web APIs. Thus, Hydra introduces the notion of operations. Simply speaking, an Operation represents the information necessary for a client to construct valid HTTP requests in order to manipulate the server's resource state. As such, the only required property of an Operation is its HTTP method. Optionally, it is also possible to describe what information the server expects or returns, including additional information about HTTP status codes that might be returned. This helps a developer to understand what to expect when invoking an operation. This information has, however, not to be considered as being complete; it is merely a hint. Developers should, e.g., expect that other HTTP status codes might be returned and program their clients accordingly.
Hydra has three predefined operation classes, namely CreateResourceOperation, ReplaceResourceOperation, and DeleteResourceOperation. As their names suggest, they can be used to implement simple CRUD functionality. More specialized operations can be easily created by subclassing these classes or their base class Operation.
The following example illustrates how representations can be augmented with information that enables clients to interact with them. A client would be able to understand that the resource in the example below can be deleted by sending an HTTP DELETE request.
The example above references Hydra's context to map properties such
as operation
and method
and values like
DeleteResourceOperation
to URLs that unambiguously
identify these concepts. It would be similarly valid JSON-LD if
these mappings would be directly embedded into the representation
or if the full URLs would be used instead. Typically, however, the
context is the same for a lot of representations in a Web API and
it thus makes sense to reduce the response size by leveraging a
remote context that can easily be cached by a client.
In Web APIs, most representations are typically very similar. Furthermore, resources often support the same operations. It thus makes sense, to collect this information in a central documentation. Traditionally, this has been done in natural language which forces developers to hardcode that knowledge into their clients. Hydra addresses this issue by making the documentation completely machine-processable. The fact that all definitions can be identified by URLs enables reuse at unprecedented granularity.
Hydra's ApiDocumentation class builds the foundation for the description of a Web API. As shown in the following example, Hydra describes a API by giving it a title, a short description, and documenting its main entry point. Furthermore, the classes known to be supported by the Web API and additional information about status codes that might be returned can be documented. This information may be used to automatically generate documentations in natural language.
In Linked Data, properties are, just as everything else, identified by IRIs and thus have global scope which implies that they have independent semantics. In contrast, properties in data models as used in common programming languages are class-dependent. Their semantics depend on the class they belong to. In data models classes are typically described by the properties they expose whereas in Linked Data properties define to which classes they belong. If no class is specified, it is assumed that a property may apply to every class.
These differences have interesting consequences. For example, the commonly asked question of which properties can be applied to an instance of a specific class can typically not be answered for Linked Data. Strictly speaking, any property which is not explicitly forbidden could be applied. This stems from the fact that Linked Data works under an open-world assumption whereas data models used by programmers typically work under a closed-world assumption. The difference is that when a closed world is assumed, everything that is not known to be true is false or vice-versa. With an open-world assumption the failure to derive a fact does not automatically imply the opposite; it embraces the fact that the knowledge is incomplete.
Mention that Hydra classes are dereferenceable resources.
Since Hydra uses classes to describe the information expected or returned by an operation, it also defines a concept to describe the properties known to be supported by a class. The following example illustrates this feature. Instead of referencing properties directly, supportedProperty references an intermediate data structure, namely instances of the SupportedProperty class. This makes it possible to define whether a specific property is required or whether it is read-only or write-only depending on the class it is associated with.
All instances of a specific class typically support the same operations. Hydra therefore features a supportedOperation property which defines the operations supported by all instances of a class.
The same feature can be used to describe the operations supported by values of a Link property. This is often helpful when certain operations depend on the permissions of the current user. It makes it, e.g., possible to show a "delete" link only if the current user has the permission to delete the resource. Otherwise, the link would simply be hidden in the representation.
Keep in mind that operations specified in an ApiDocumentation may fail at runtime as either resources or the ApiDocumentation itself have changed since they have been retrieved. A simple strategy to try to recover from such an error is to reload the ApiDocumentation.
Describe the various properties of an operation.
The first step when trying to access a Web API is to find an entry
point. Typically, this is done by looking for documentation on the
API publisher's homepage. Hydra enables the API's main entry point
to be discovered automatically if the API publisher marks his
responses with a special HTTP Link Header as defined in [[RFC5988]].
A Hydra client would look for a Link Header with a relation type
http://www.w3.org/ns/hydra/core#apiDocumentation
(this is
the IRI identifying the hydra:apiDocumentation property).
In the following example, a Hydra client simply accesses the
homepage of an API publisher (http://www.example.com
)
to find the entry point of its API. A client may use an HTTP GET or
HEAD request. The difference between the two is that the former may
return a message-body in the response whereas the latter will not;
otherwise they are identical.
The response in the example above contains an HTTP Link Header
pointing to http://api.example.com/doc/
.
Retrieving that resource, the client would obtain a
Hydra API documentation defining the API's main entry
point:
Please note that in most cases the entry point will already be known to the client. Thus, the discovery of the API documentation using HTTP Link Headers is typically not necessary as the concepts used in responses from the API will dereference to their documentation.
Describe Hydra's Resource class? Or should that better be described somewhere in the beginning?
In many situations, it makes sense to expose resources that reference a set of somehow related resources. Results of a search query or entries of an address book are just two examples. To simplify such use cases, Hydra defines the two classes hydra:Collection and hydra:PartialCollectionView.
A hydra:Collection can be used to reference a set of resources as follows:
As shown in the example above, member items can either consist of solely a link or also include some properties. In some cases embedding member properties directly in the collection is beneficial as it may reduce the number of HTTP requests necessary to get enough information to process the result.
Since collections may become very large, Web APIs often chose to split a collection into multiple pages. In Hydra, that can be achieved with a hydra:PartialCollectionView. It describes a specific view on the collection which represents only a subset of the collection's members. A PartialCollectionView may contain links to the the first, next, previous, and last PartialCollectionView which allows a client to find all members of a Collection.
Say that all these properties are optional? What about first and, perhaps more interestingly, last?
Sometimes, it is impossible for a server to construct a URL because the URL depends on information only known by the client. A typical use case are URLs which enable a client to query the server. In such a case, the server cannot construct the URL because it does not know the query the client is interested in. What the server can do however, is to give the client a template to construct such a URL at runtime. In Hydra, the IriTemplate class is used to do so.
An IriTemplate consists of a template literal and a set of mappings. Each IriTemplateMapping maps a variable used in the template to a property and may optionally specify whether that variable is required or not. The syntax of the template literal is specified by its datatype and defaults to the [[!RFC6570]] URI Template syntax, which can be explicitly indicated by hydra:Rfc6570Template.
The example above maps the variable q
to Hydra's
freetextQuery property and marks it as required.
As its name suggests, the freetextQuery property can be used
for free text queries.
A template syntax only details how to fill out simple string values, but not how to derive such string values from typed values, language-tagged strings, or IRIs. Hydra addresses this by specifying how such values are to be serialized as strings. The serialization of an IriTemplate's variables can be described by setting the variableRepresentation property to BasicRepresentation or ExplicitRepresentation. The BasicRepresentation represents values by their lexical form. It omits type and language information and does not differentiate between IRIs and literals. The ExplicitRepresentation, on the other hand, includes type and language information and differentiates between IRIs and literals by serializing values as follows:
"
).@
symbol is
appended after the double-quoted lexical form, followed by a
non-empty [[BCP47]] language code.^^
) are appended after the double-quoted literal,
followed by the full datatype IRI.In both representations characters MUST NOT be escaped. In case the representation format is not explicitly described, clients SHOULD use the BasicRepresentation by default.
Although ExplicitRepresentation use of
@
and ^^
is similar, it is not the
same as the [[Turtle]] representation for literals. Turtle literals
require escaping of special characters, surround datatype IRIs with
angular brackets (<
and >
), and also
allow single quotes ('
) to indicate literals.
ExplicitRepresentation values must not be escaped, IRIs must
not be surrounded by any character, and only double quotes can
indicate literals.
Below are some example values serialized in the different
representations as well as the result of expanding the IRI template
http://example.com/find/{value}
with the respective
value.
Similar to how Hydra's Link class allows the definition of properties that represent hyperlinks as described in , the TemplatedLink class allows the definition of properties whose value are IRI templates. Hydra predefines one such property, namely the search property which can be used to document available search interfaces.
HTTP status codes have well defined semantics and can be used to
signal the outcome of an operation. Unfortunately, however, HTTP
status codes by themselves are often not specific enough, making it
difficult to understand the real cause of an error. For
instance, a 429 Too Many Requests
response is rarely
informative enough by itself. To address this issue, Hydra defines
a Status class which allows additional
information to be associated with an HTTP status code.
An ApiDocumentation or an Operation may document the status codes that might be returned by the server using the possibleStatus property as described in . This allows a developer to understand what to expect when invoking an operation. It has, however, not to be considered as an extensive list of all potentially returned status codes; it is merely a hint. Developers should expect to encounter other HTTP status codes as well.
A server may also return a Status directly in a response. When doing so, it often makes sense to subclass the Status to make its semantics more explicit. Hydra defines just one such subclass, namely the Error class. This provides an extensible framework to communicate error details to a client.

怎样在admin中添加菜单 http://codex.wordpress.org/Adding_Administration_Menus
admin管理中添加脚本和样式表资源：http://codex.wordpress.org/Plugin_API/Action_Reference/admin_enqueue_scripts
plugins_url的调用需要注意场合，应该在hook方法中调用，否则得不到值。
遇到的headers already sent问题:
插件在本地运行的好好的，发送到网站上启用后报：这个插件在启用的过程中产生了xx 个字符的异常输出。插件是可以运行的，但是退出admin时就一大堆headers already sent(xxxx 第xx行),连xmlrpc也不能用了。删除插件就没这个问题。
我在网上查，发现php utf-8 bom这个问题。
php utf-8的 BOM 问题解决 http://blog.csdn.net/ok7758521ok/article/details/1756052
我就以为是这个问题，但是用unicode 16进制查看却没有发现bom头。
后来才发现eclipse utf-8格式本身就是不带bom头的。 http://stackoverflow.com/questions/2905582/working-with-utf-8-files-in-eclipse
Both bug 78455 ("Provide an option to force writing a BOM to UTF-8 files") and bug 136854 don't leave much hope for such an option.
The support for encoding in the workspace is based on what is available from Java.
For any given resource in the workspace, it is possible to obtain a charset string that can be used with any Java APIs that take charset strings.
Examples are:
- '
US-ASCII
',- '
UTF-8
',- '
Cp1252
',- '
UTF-16
' (Big Endian, BOM inserted automatically),- '
UTF-16BE
' (Big Endian, BOM not inserted automatically),- '
UTF-16LE
' (Little Endian, BOM not inserted automatically).For Java encodings, except for the 'UTF-16' encoding, BOMs are not inserted (when writing) or discarded (when reading) for free.
Even if this is puzzling to end users, this is how all Java applications work.
If applications want to support creating UTF-8 files with BOMs to match their users' expectations, they need to provide such capability on their own (as neither Java nor the Resources model will help with that).
Eclipse does provide some improvements towards detecting BOMs, but not with generating or skipping them.
真是冤大头，我还用notepad++的格式/转为utf-8 wihout BOM转换了一下，确实不是这个原因。
最后发现那个报错已经说明了是哪一行，那一行是个php code之外的空白，把空白删除了就可以了！
再查查wordpress plugin资料，原来插件主文件代码里是要注意空白的。如果在展示上有空白，建议写在另外的php文件中在require进来。

Bed-Stuy Strong is a group of neighbors helping neighbors in a spirit of solidarity. We are a mutual aid network of over 4,000 people from across Bed-Stuy who are supporting each other and our communities during the COVID-19 crisis. We crowdsource donations and use them to provide no-contact grocery deliveries for vulnerable members of our Bed-Stuy communities.
All of our members are ordinary folks volunteering their time and effort. We are not a government agency or a non-profit. You can learn more about our guiding principles here.
Given the times, Bed-Stuy Strong faces an incredible amount of need in our communities. Every day we receive hundreds of calls. We spend several thousand dollars daily to try to make sure our neighbors do not go hungry. We ask for your patience and support as we try to connect our community’s help to our community’s need.
I am in need.
If you live in Bed-Stuy and are experiencing hunger, please leave us a voicemail or send a text message to<PHONE_NUMBER>.  As of March 3rd, our phone line opens Wednesdays at 3PM and closes once we have reached our capacity to deliver for the week.
As of mid-January 2021, we have moved to a set number of weekly food delivery slots based on the number of people who can deliver and to avoid a long wait time for delivery.
We apologize that we can’t meet your request immediately. We have received thousands of messages and respond in the order that requests are received, so there is no need to leave multiple voicemails.
We understand that you might need food quicker than we can get it to you. If you are experiencing hunger right now, please see our below list of food resources in Bed-Stuy or go to NYC.gov/getFood. If you would like to hear a list of these resources over the phone, please call<PHONE_NUMBER>. Thank you for your patience. Our thoughts are with you.
A detailed list of food assistance options in Bed-Stuy and citywide is available here: bedstuystrong.com/resources
Anyone willing to go to a grocery store to shop for another person and be reimbursed for the shopping out of our community fund can become a Bed-Stuy Strong delivery volunteer; multiple delivery volunteers have also received food support. More delivery volunteers mean that more people can get food each week. See below for details on how to join. Bed-Stuy Strong is built on the belief that all of us have needs and all of us can offer help. We believe in community care, joined hands, and dignity afford to all people.
I need support to get a vaccine or want to support my elders in getting a vaccine.
We know that it isn't easy for everyone to navigate the technology and changing requirements of getting vaccinated. Bed-Stuy Strong is here to help!
If you're totally comfortable booking an appointment for yourself / your neighbor online, check out our guide to getting an appointment.
Are you an elder or essential worker who can fill out a short form yourself, but can't go through the whole booking process? You can check your eligibility here, and fill out Epicenter NYC's form directly.
Any Bed-Stuy neighbors who totally can't navigate the vaccine system themselves can call or text<PHONE_NUMBER> to receive help figuring out their eligibility, scheduling an appointment, or getting to an appointment. A Bed-Stuy Strong member will call back, ideally within a week, to answer questions and, if eligible, help you submit an Epicenter NYC intake form. You will receive a confirmation email or phone call from Epicenter once your appointment has been confirmed.
I want to donate.
One hundred percent of donations to Bed-Stuy Strong are used to purchase groceries and basic supplies for vulnerable neighbors. Households then receive what they need from our network of delivery volunteers – ordinary Bed-Stuy residents who are looking to help members of their community.
We are grateful for every contribution. Every dollar you give has a direct impact on the safety and well-being of our Bed-Stuy neighbors. Since our founding in March, Bed-Stuy Strong has purchased and delivered a week’s supply of groceries for over 22,000 neighbors, providing an estimated half a million meals. Many of the neighbors we've served are elderly, immunocompromised, or disabled.
We accept financial donations using any of these platforms:
Venmo: bedstuystrong (last 4 digits of phone number: 7668)
Cash App: $bedstuystrong
Paypal<EMAIL_ADDRESS>Zelle<EMAIL_ADDRESS>We are now able to accept tax-deductible credit card and check donations through our ioby page. To donate by check, mail a check to ioby.
What is mutual aid?
Many definitions exist, but a simple one is: voluntary, often reciprocal care + support exchanged between people of a community, in a horizontal way, with solidarity and joined hands. We do our work in the shadow of powerful organizing from the Black Panthers’ free clinics to abolitionist networks, and the legacy of neighbors helping neighbors that has existed in Bed-Stuy since time immemorial.
I want to join. What’s next?
We welcome anyone with strong ties to Bed-Stuy (current resident of, working in, family home, etc.) to become a member of the BSS community. Our members come from all walks of life, from service workers to software engineers to artists to full-time parents and caretakers, and represent a mix of newer and longstanding residents of Bed-Stuy.
We ask each other for help when we need it, and provide support when able to, in a spirit of solidarity and resourcefulness aligned with our guiding principles. The aid we offer each other shows up in a variety of ways, whether it’s collecting and redistributing supplies, providing social support, learning from one another about the political moment, or posting photos of our pets to make each other smile.
How does membership work?
We communicate, co-envision, organize, and share asks, offers, community news, volunteer and advocacy opportunities through these channels:
- BSS Members Hub (an online website including community calendar, volunteer opportunities)
- Slack (an online forum for organizing and coordinating)
- Email newsletter and Instagram (events, asks/offers)
- Text message updates (optional)
Ready to be a BSS member?
Sign up here! We’re excited to be in community with you.
I’m interested in partnering.
As unemployment and economic hardship continues to grow due to the COVID-19 crisis, we are continuing to evolve to ensure we can continue supporting our neighbors in need. As part of this evolution, we are exploring potential partnerships with Brooklyn-based organizations and businesses that have expertise in food provision and distribution and access to physical space. If you’re interested in discussing partnership opportunities, please email us at<EMAIL_ADDRESS>Media requests.
If you’re a member of the media and would like to get in touch, please email us at bedstuystrong@bedstuystrong.com.

Windrush exhibition finds permanent home
The stories of those who came to British shores from the Caribbean has got a permanent home in Sandwell.
by James VukmirovicAn exhibition celebrating the contributions and achievements of the migrants who arrived in Britain between 1948 and 1971 was the centrepiece of Sandwell Libraries Black History Month display.
And the exhibition, which features images, biographical information and poems about the people involved, remains at Central Library in West Bromwich.
It will help to raise awareness of the input the Windrush generation had in restoring Britain's labour shortage in the aftermath of the Second World War.
The exhibition has been put together by Poet Amanda Hemmings, who wrote one of the poems featured in the exhibition "1954" about her grandfather's experiences of migrating to Britain from Jamaica.
She spoke about the positive feedback she had received from the community about the exhibition.
She said: "Feedback of the exhibition includes people saying it has inspired diverse groups of younger generations to have conversations with parents and grandparents on their early life experiences.
"One person said to me: ‘Your poem made me talk to my Grandad and start asking him questions. He’s 93 and not very well, but he started to smile when he was telling me about the friends he made when he came to England; we were both laughing, he seemed so much happier in himself.’"
The exhibition can be seen at Central Library, High Street, West Bromwich.

Customers are slamming Macy's, Best Buy, and Target for opening stores on Thanksgiving
by Mary Hanbury- Macy’s, JCPenney, Best Buy, and others are being criticized for opening their doors on Thanksgiving.
- Angry shoppers have complained on Twitter over the past few days. “Thanksgiving is a day of giving thanks, not a day for corporate capitalism,” one person wrote this week.
- At least 35 retailers – including Costco, Lowe’s, and TJ Maxx – have said they will keep stores closed on Thanksgiving, and there’s evidence the shopping day doesn’t carry the same weight it once did.

Not everyone is a fan of Thanksgiving Day sales.
Over the past few days, angry shoppers on Twitter have complained about the retailers that have chosen to open stores early for Black Friday sales on Thanksgiving.
According to BestBlackFriday.com, at least 19 retailers including Macy’s, JCPenney, and Best Buy are scheduled to be open over the holiday. Most of these stores plan to open in the afternoon.
“Thanksgiving is a day of giving thanks, not a day for corporate capitalism,” one person wrote on Twitter.
“Opening your stores on Thanksgiving is UNAMERICAN,” another wrote. “It is a truly disgusting practice to make people work on one of the truly American holidays.
At least 35 retailers won’t be opening for Thanksgiving this year, however, amid evidence this shopping day doesn’t carry the same weight it once did. As consumers are increasingly shopping for deals online, they feel less of a need to line up outside stores for one big day of shopping. Moreover, they’re used to having deals year-round, which takes the pressure off Black Friday.

1. What is your take on the DBA/EDA expereince?
My take on the experience that Shereef just talked about sounds exciting and makes me hopeful that I can complete this course.
2. What are your impressions?
My impression are that this seems well put together, although I am currently struggling with some parts of this first sprint, hearing that it is all part of the whole learning process, puts me at ease a little bit.
3. How do you see yourself engaging with this type of culture?
My strengths are more in the culture of communication and pairing and learning from others, so I know that the culture aspect of the journey will be some what much easier than actually learning all the technical things.
4. Have your expectations of EDA changed? If so, how?
Not so much my expectations, but my outlook has been reconfirmed that it's going to be challenging but possible if you have the attitude.
5. Are you excited to participate in this kind of learning environment? Does it make you nervous?
I am very excited to learn, I know it will be intense, and I am most nervous about not being able to understand all the technical things, I am already struggling with certain concepts in this first sprint.

SASSA warns against social grant abuse ahead of the festive season
The agency dispensed safety tips to ensure that recipients do not fall victim to crime during this busy period
by SUPPLIED CONTENTMBOMBELA – The South African Social Security Agency (SASSA) is embarking on a campaign to spread awareness to social grant beneficiaries about wise spending this festive season.
In a statement, Senzeni Ngubeni, the Mpumalanga SASSA spokesman, said, “Beneficiaries must note that the social grant payment is not meant for a luxury life and to pay back loan shark debt, but must be utilised to buy basic needs. Social grant is an intervention for poverty alleviation.”
He stressed that parents and legal guardians of child support grant beneficiaries needed to remember that the social grant was not meant for their needs but for the child’s.

“The child must have proper clothing and nutritious food.”
Ngubeni provided the following tips for being safe during the festive season:
- Be wary of people loitering around the ATM and ensure that you are not followed.
- Check your balance regularly and report discrepancies to your bank immediately.
- After you have completed your transaction successfully, leave the ATM area immediately. Be cautious of strangers requesting that you return to finalise or close the transaction because they are unable to transact. They may be skimming your card.
- Some fraudsters wait until you have drawn your cash to take advantage.

“We wish all social grants beneficiaries a happy festive season,” he concluded.
Grant beneficiaries who require more information should call the toll-free number: 0800-60-10-11 from 08:00 to 16:00 during weekdays Monday to Friday.

Revenge of the Pancakes This problem came from a Google Code Jam project that was made available online in 2016. Feel free to use the language you feel most comfortable in, but Go is our preferred language if you are able to use it. Problem
The Infinite House of Pancakes has just introduced a new kind of pancake! It has a happy face made of chocolate chips on one side (the "happy side"), and nothing on the other side (the "blank side"). You are the head waiter on duty, and the kitchen has just given you a stack of pancakes to serve to a customer. Like any good pancake server, you have Xray pancake vision, and you can see whether each pancake in the stack has the happy side up or the blank side up. You think the customer will be happiest if every pancake is happy side up when you serve them.
You know the following maneuver: carefully lift up some number of pancakes (possibly all of them) from the top of the stack, flip that entire group over, and then put the group back down on top of any pancakes that you did not lift up. When flipping a group of pancakes, you flip the entire group in one motion; you do not individually flip each pancake. Formally: if we number the pancakes 1, 2, ..., N from top to bottom, you choose the top i pancakes to flip. Then, after the flip, the stack is i , i 1, ..., 2, 1, i +1, i +2, ..., N . Pancakes 1, 2, ..., i now have the opposite side up, whereas pancakes i +1, i +2, ..., N have the same side up that they had up before.
For example, let's denote the happy side as + and the blank side as . Suppose that the stack, starting from the top, is --+--. One valid way to execute the maneuver would be to pick up the top three, flip the entire group, and put them back down on the remaining fourth pancake (which would stay where it is and remain unchanged). The new state of the stack would then be -++-. The other valid ways would be to pick up and flip the top one, the top two, or all four. It would not be valid to choose and flip the middle two or the bottom one, for example; you can only take some number off the top. You will not serve the customer until every pancake is happy side up, but you don't want the pancakes to get cold, so you have to act fast! What is the smallest number of times you will need to execute the maneuver to get all the pancakes happy side up, if you make optimal choices?
The first line of the input gives the number of test cases, T . T test cases follow. Each consists of one line with a string S , each character of which is either + (which represents a pancake that is initially happy side up) or - (which represents a pancake that is initially blank side up). The string, when read left to right, represents the stack when viewed from top to bottom.
For each test case, output one line containing Case #x: y , where x is the test case number (starting from 1) and y is the minimum number of times you will need to execute the maneuver to get all the pancakes happy side up.


Setting up your computer for these tutorials
Let’s setup your machine for these tutorials. The goal is to go through some pain now so you have a decent development environment later on, i.e. no short cuts. This does not go into why we need these tools, not yet at least.
Overview of requirements
The installation will depend on your operating system, but overall, you will need:
- Python 2.x – there are plans to update/include Python 3.x
- git – an intro given here
- A C compiler
- pip
- virtualenv
- virtualenvwrapper (optional but a very handy tool for managing virtualenvs)
Mac OS X
Python
Macs come with Python pre-installed. To check, open up the Terminal application (Applications → Utilities → Terminal like so), then type python
:
1 2 3 4 5 | $ python
Python 2.7.2 (default, Jun 20 2012, 16:23:33)
[GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple/clang-418.0.60)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>>
|
Python.org has a good Python on the Mac page if the above does not work for you.
git
You will need to install git on your machine through their download page. You can then follow the Save your Progress page to set it up.
C compiler
You will need the XCode application. Once you have XCode on your machine, you will need to navigate to Preferences → Downloads, then select Command Line Tools to download & install (this may take a while, get some coffee, go take a shower).
This gives you the GCC or the GNU Compiler Collection. To test installation, within the Terminal application, type gcc
and you should get the following:
1 2 | $ gcc
i686-apple-darwin11-llvm-gcc-4.2: no input files
|
pip
pip, stands for “python install python”, is a tool for installing and managing Python packages. Within your Terminal application, use the following commands (ignore the leading $
as that is your terminal prompt) for downloading & installing. It may prompt you for your computer login password.
1 2 3 4 5 | $ sudo curl -O http://python-distribute.org/distribute_setup.py | python
$ sudo curl -O https://raw.github.com/pypa/pip/master/contrib/get-pip.py | python
$ pip
Usage: pip COMMAND [OPTIONS]
You must give a command (use "pip help" to see a list of commands)
|
virtualenv & virtualenvwrapper
virtualenv creates isolated environments for each of your Python projects. It helps to solve version & dependency problems with multple Python installations and/or multiple versions of different Python packages. We’ll use pip
to install it:
1 | $ sudo pip install virtualenv
|
virtualenvwrapper is a great (but not required) tool for using virtualenv by simplifying the commands that virtualenv needs. We’ll use pip
again to install it:
1 2 3 4 | $ sudo pip install virtualenvwrapper
$ export WORKON_HOME=~/Envs
$ mkdir -p $WORKON_HOME
$ source /usr/local/bin/virtualenvwrapper.sh
|
Now let’s test our installation and get familiar with creating & using virtual environments:
1 2 3 4 5 6 7 8 9 10 11 | $ mkvirtualenv TestEnv
Installing
distribute..........................................
....................................................
....................................................
...............................done.

virtualenvwrapper.user_scripts Creating /Users/lynnroot/Envs/TestEnv/bin/postdeactivate
virtualenvwrapper.user_scripts Creating /Users/lynnroot/Envs/TestEnv/bin/preactivate
virtualenvwrapper.user_scripts Creating /Users/lynnroot/Envs/TestEnv/bin/postactivate
virtualenvwrapper.user_scripts creating /Users/lynnroot/Envs/TestEnv/bin/get_env_details
|
Now that you made a virtual environment called TestEnv
, you should see (TestEnv)
before your prompt:
1 | (TestEnv) $
|
Let’s play around with commands for virtualenvwrapper:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 | # deactivate the TestEnv

As you can see, you’ll need to activate a virtual environment in order to access the libraries that you installed. Here’s a run-down of useful commands for pip, virtualenv & virtualenvwrapper:
mkvirtualenv [ENV_NAME]
– creates and activates a fresh virtual environmentworkon [ENV_NAME]
– activates an already-created virtual environmentdeactivate
– deactivates the virtual environment that is currently active- within an activated virtualenv,
pip install [PACKAGE_NAME]
installs a package into the virtualenv - within an activated virtualenv,
pip freeze
lists the packages that is installed & accessible within the virtualenv
You’re good to go with your setup! Go start on dataviz!

Discover Permanent Eraser
Erasing |

When you normally delete files on the Mac, the operating system is only forgetting where those particular files are placed, while the data still physically remains on the drive. Beginning with Mac OS X 10.3, Apple enhanced its security by introducing the Secure Empty Trash feature, which follows the U.S. DoD pattern of overwriting data seven times. This feature was then later removed in OS X 10.11 El Capitan. Permanent Eraser provides additional wiping methods such as the 3-pass DoE or 35-pass Gutmann algorithms. This utility overwrites your data multiple times, scrambles the original file name, and truncates the file size to nothing before Permanent Eraser finally unlinks it from the system. Once your data has been erased, it can no longer be read through traditional means. Permanent Eraser fills in what the Finder forgot! Simply drag a CD-RW or DVD-RW onto Permanent Eraser to erase the disc's contents. |

Why Do You Need Title Insurance?
Title Insurance.
It’s a term we hear and see frequently - we see reference to it in the
Sunday real estate section, in advertisements and in conversations with
real estate brokers. If you’ve purchased a home before, you’re probably
familiar with the benefits and procedures of title insurance. But if
this is your first home, you may wonder, “Why do I need another
insurance policy? It’s just one more bill to pay.”
The answer is simple: The purchase of a home is most likely one of the
most expensive and important purchases you will ever make. You, and your
mortgage lender, want to make sure that the property is indeed yours -
lock, stock and barrel - and that no individual or government entity has
any right, lien, claim to your property.
Title insurance companies are in business to make sure your rights and
interests to the property are clear, that transfer of title takes place
efficiently and correctly and that your interests as a homebuyer are
protected to the maximum degree.
Title insurance companies provide services to buyers, sellers, real
estate developers, builders, mortgage lenders and others who have an
interest in a real estate transfer. Title companies routinely issue two
types of policies - “owner’s”, which cover you, the homebuyer; and
“lender’s”, which covers the bank, savings and loan or other lending
institution over the life of the loan. Both are issued at the time of
purchase for a modest, one-time premium.
Before issuing a policy, however, the title company performs an
extensive search of relevant public records to determine if anyone other
than you has an interest in the property. The search may be performed by
title company personnel using either public records or more likely,
information gathered, reorganized and indexed in the company’s title
plant.
With such a thorough examination of records, any title problems usually
can be found and cleared up prior to your purchase of the property. Once
a title policy is issued, if for some reason any claim which is covered
under your title policy is ever filed against your property, the title
company will pay the legal fee involved in defense of your rights, as
well as any covered loss arising from a valid claim. That protection,
which is in effect as long as you or your heirs own the property, is
yours for a one-time premium paid at the time of purchase.
The fact that title companies work to eliminate risks before they
develop makes the title insurance decidedly different from other types
of insurance you may have purchased. Most forms of insurance assume
risks by providing financial protection through a pooling of risks for
losses arising from an unforeseen event, say a fire, theft or accident.
The purpose of title insurance, on the other hand, is to eliminate risks
and prevent losses caused by defects in title that happened in the past.
Risks are examined and mitigated before property changes hands.
This risk elimination has benefits to both you, the homebuyer, and the
title company: it minimizes the chances adverse claims might be raised,
and by so doing reduces the number of claims that have to be defended or
satisfied. This keeps costs down for the title company and your title
premiums low.
Buying a home is a big step emotionally and financially. With title
insurance you are assured that any valid claim against your property
will be borne by the title company, and that the odds of a claim being
filed are slim indeed.
Isn’t sleeping well at night, knowing your home is yours, reason enough
for title insurance?

No prosecutions over death of tragic teen Amber Peat
The 13-year-old was found hanged three days after her disappearance
by Matt JarramNo-one will be prosecuted over the death of 13-year-old Amber Peat who hanged herself in bushes near her home.
Tragic Amber, a former pupil of Tibshelf Community School, in Derbyshire, was found hanged in bushes, on June 2, 2015, three days after going missing from her home in Mansfield.
Today, following a new review of evidence, the Crown Prosecution Service spokesman said: "Following the inquest into the tragic death of Amber Peat, we have reviewed the case once more in light of the coroner’s findings and further material gathered by Nottinghamshire Police.
"After careful consideration of all the available evidence, we have concluded there is insufficient evidence to prosecute anyone for criminal offences relating to Amber’s treatment up to the time of her death.
"Amber’s relatives have been updated about the decision. Our thoughts remain with them."
When evidence not previously considered is heard by a coroner, this can be investigated by the police, Nottinghamshire Live reports.
In this instance, Nottinghamshire Police referred some new evidence to the CPS and asked them to revisit the charging decision in the light of this material.
This evidence was looked at, alongside all the evidence from the original investigation. The conclusion was that the additional evidence did not materially change the earlier CPS decision from 2016.
As the investigation and review have resulted in a decision not to bring criminal charges, the CPS said it would not be appropriate to name any suspects.
A serious case review released in March found that although there were concerns for Amber's 'emotional well-being', her death could not have been predicted.
The report said Amber felt like she was to blame for many difficulties within the family, while and information-sharing between organisations was found to be 'limited'.
And an inquest in February heard the schoolgirl was described as 'bright and outgoing', but she appeared withdrawn when with her mother, Kelly Peat and stepfather Daniel Peat.
The inquest was told that Amber ran away several times when the family lived in Tibshelf and Mansfield.
But the coroner suggested it was "significant" that this never happened while Mr Peat was in prison, serving time for fraud.
Her mother suspected her of "attention-seeking" on the last night Amber left home following an argument. The disappearance was reported to police seven hours later, after the couple visited a Tesco and a car wash.
The coroner recorded a narrative conclusion on Amber but criticised health, education and social care teams in Notts and Derbyshire.
The coroner said Amber was failed by organisations which should have protected her.

I am working as a Business Analyst at Shloklabs
since the last quarter of 2020. I am more interested towards the technology and manipulating the
way it works. Since my childhood its been a habit now, when I get a toy I enjoy more to open and explore
what's within it than just use and play like it is meant to!!
OKAY!! You tell me what's fun playing by its rules XD.
Well! that's pretty much ME!! That is enough of me for now.
I work as a Business Analyst in a product based company, I take client requirements and analyse to fit their requirements without disrupting the existing Product
I am a programmer by passion. My interest in programming started during my school days
which made me who I am today. I have gained my skills in the languages listed below
out of my personal interest.
Having said this, my interest in programming didn't stop here. I became a tutor to share my
knowledge for the betterment of enthusiasts like me. I've trained over 60 people till now. I am the
founder and CEO of SOLOTUTOR, an institution that helps enthusiasts learn and polish technical
skills.
I am a proud programmer and trainer with big dreams. My prime goal is to make a global impact.
