Return an estimate of the reciprocal of the L1 condition number of the Complex matrix used to construct
this instance.
-

-
Return the determinant of the matrix used to construct this instance.
-
inverse()

ComplexLU
public ComplexLU(Complex a[][]) throws IllegalArgumentException, MathException
- Create the LU factorization of a square Complex matrix.
- Parameters:
- a - Complex square matrix to be factored.
- Throws: IllegalArgumentException
- This exception is issued when the row lengths of
input matrix a are not equal (i.e. the matrix edges are "jagged".)
- Throws: MathException
- This exception is issued when the input matrix a is singular.
-
Algorithm:
-
The LU factorization is done using scaled partial pivoting. Scaled
partial pivoting differs from partial pivoting in that the pivoting
strategy is the same as if each row were scaled to have the same
infinity norm. The constructor is based on the LINPACK routine ZGECO.
-
Example:
-
import VisualNumerics.math.*;
import java.io.*;
class testCLU {
public static void main(String args[]) {
int i, j, n=3;
double cond=0.0e0;
Complex fac[][]=null, ainv[][], x[], dtrm;
Complex a[][] = new Complex[n][n];
Complex b[] = new Complex[n];
for(i=0;i <
n;i++){
for(j=0;j <
n;j++){
a[i][j] = new Complex((double)(j+3*i), (double)(j-i));
a[j][i] = new Complex(a[i][j].re, 0.0e0);
}
b[i] = new Complex((double)(7+i));
}
try {
ComplexLU lu = new ComplexLU(a);
x = lu.solve(b);
ainv = lu.inverse();
cond = lu.condition();
dtrm = lu.determinant();
... print output ...
} catch (IllegalArgumentException e) {
System.err.println("From testcomplexLU "+e);
} catch (MathException e) {
System.err.println("From testcomplexLU "+e);
}
}
}
solve
public Complex[] solve(Complex b[])
- Return the solution x of the linear system Ax=b using the LU
factorization of A.
- Parameters:
- b - Complex vector containing the right-hand side of the linear system.
- Returns:
- A Complex vector containing the solution to the system of
linear equations.
-
Algorithm:
-
The ComplexLU constructor computes an LU factorization of a complex matrix.
The solution to Ax = b is found by solving the triangular systems Ly = b
and Ux = y. The forward elimination step consists of solving the system
Ly = b by applying the same permutations and elimination operations to b
that were applied to the columns of A in the factorization. The backward
substitution step consists of solving the triangular system Ux = y for x.
This method is based on the LINPACK routine ZGESL.
inverse
public Complex[][] inverse()
- Return the inverse of the matrix used to construct this instance.
- Returns:
- A Complex[][] matrix containing the inverse of the
matrix used to construct this instance.
-
Algorithm:
-
The ComplexLU constructor computes an LU factorization of the
complex matrix. This factorization is then used by solve with
successive columns of the identity matrix to compute successive
columns of the inverse matrix.
determinant
public Complex determinant()
- Return the determinant of the matrix used to construct this instance.
- Returns:
- A double scalar containing the determinant of the
matrix used to construct this instance.
-
Algorithm:
-
The ComplexLU constructor computes an LU factorization of the
complex matrix. The product of the diagonal elements of the LU
factorization is then obtained. The sign of this product is then
adjusted based on the number of pivoting interchanges that have
occurred. This method is based on LINPACK routine ZGEDI.
condition
public double condition()
- Return an estimate of the reciprocal of the L1 condition number of the Complex matrix used to construct
this instance.
- Returns:
- An estimate of the reciprocal of the L
1 condition number of the
Complex matrix used to construct this instance.
-
Algorithm:
-
The ComplexLU constructor computes an LU factorization of the complex matrix.
This factorization is then used by this method in determining the condition
number. The L
1 condition number of a matrix A is defined to be the 1-norm
of A times the 1-norm of A inverse. Since it is expensive to compute the
1-norm of A inverse, the condition number is only estimated. The estimation
algorithm is the same as used by LINPACK routine ZGECO. A condition
number less than approximately 2.22e-16 indicates that very small
changes in A can cause very large changes in the solution X of a linear
system involving A.
ipvt
public int[] ipvt()
- Return a vector containing information for
the LU factorization of the matrix.
- Returns:
- An int vector containing the pivoting
information for the LU factorization.

JSON Web Token (JWT) is a compact token format intended for space constrained environments such as HTTP Authorization headers and URI query parameters. JWTs encode claims to be transmitted as a JSON object (as defined in RFC 4627 (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627]) that is base64url encoded and digitally signed and/or encrypted. Signing is accomplished using JSON Web Signature (JWS) [JWS] (Jones, M., Balfanz, D., Bradley, J., Goland, Y., Panzer, J., Sakimura, N., and P. Tarjan, “JSON Web Signature (JWS),” December 2011.). Encryption is accomplished using JSON Web Encryption (JWE) [JWE] (Jones, M., Rescorla, E., and J. Hildebrand, “JSON Web Encryption (JWE),” December 2011.).
The suggested pronunciation of JWT is the same as the English word "jot".
| TOC |
- JSON Web Token (JWT)
- A string consisting of three parts: the Encoded JWT Header, the JWT Second Part, and the JWT Third Part, in that order, with the parts being separated by period ('.') characters, and each part containing base64url encoded content.
- JWT Header
- A string representing a JSON object that describes the cryptographic operations applied to the JWT. When the JWT is signed, the JWT Header is the JWS Header. When the JWT is encrypted, the JWT Header is the JWE Header.
- Header Parameter Names
- The names of the members within the JWT Header.
- Header Parameter Values
- The values of the members within the JWT Header.
- JWT Second Part
- When the JWT is signed, the JWT Second Part is the Encoded JWS Payload. When the JWT is encrypted, the JWT Second Part is the Encoded JWE Encrypted Key.
- JWT Third Part
- When the JWT is signed, the JWT Third Part is the Encoded JWS Signature. When the JWT is encrypted, the JWT Third Part is the Encoded JWE Ciphertext.
- JWT Claims Set
- A string representing a JSON object that contains the claims conveyed by the JWT. When the JWT is signed, the bytes of the UTF-8 representation of the JWT Claims Set are base64url encoded to create the Encoded JWS Payload. When the JWT is encrypted, the bytes of the UTF-8 representation of the JWT Claims Set are used as the JWE Plaintext.
- Claim Names
- The names of the members of the JSON object represented by the JWT Claims Set.
- Claim Values
- The values of the members of the JSON object represented by the JWT Claims Set.
- Encoded JWT Header
- Base64url encoding of the bytes of the UTF-8 RFC 3629 (Yergeau, F., “UTF-8, a transformation format of ISO 10646,” November 2003.) [RFC3629] representation of the JWT Header.
- Base64url Encoding
- For the purposes of this specification, this term always refers to the URL- and filename-safe Base64 encoding described in RFC 4648 (Josefsson, S., “The Base16, Base32, and Base64 Data Encodings,” October 2006.) [RFC4648], Section 5, with the (non URL-safe) '=' padding characters omitted, as permitted by Section 3.2. (See Appendix C of [JWS] (Jones, M., Balfanz, D., Bradley, J., Goland, Y., Panzer, J., Sakimura, N., and P. Tarjan, “JSON Web Signature (JWS),” December 2011.) for notes on implementing base64url encoding without padding.)
| TOC |
JWTs represent a set of claims as a JSON object that is base64url encoded and digitally signed and/or encrypted. The JWT Claims Set represents this JSON object. As per RFC 4627 (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] Section 2.2, the JSON object consists of zero or more name/value pairs (or members), where the names are strings and the values are arbitrary JSON values. These members are the claims represented by the JWT.
The member names within the JWT Claims Set are referred to as Claim Names. The corresponding values are referred to as Claim Values.
The bytes of the UTF-8 representation of the JWT Claims Set are signed in the manner described in JSON Web Signature (JWS) [JWS] (Jones, M., Balfanz, D., Bradley, J., Goland, Y., Panzer, J., Sakimura, N., and P. Tarjan, “JSON Web Signature (JWS),” December 2011.) and/or encrypted in the manner described in JSON Web Encryption (JWE) [JWE] (Jones, M., Rescorla, E., and J. Hildebrand, “JSON Web Encryption (JWE),” December 2011.).
The contents of the JWT Header describe the cryptographic operations applied to the JWT Claims Set. If the JWT Header is a JWS Header, the claims are signed. If the JWT Header is a JWE Header, the claims are encrypted.
A JWT is represented as the concatenation of the Encoded JWT Header, the JWT Second Part, and the JWT Third Part, in that order, with the parts being separated by period ('.') characters. When signed, the three parts of the JWT are the three parts of a JWS used to represent the JWT. When encrypted, the three parts of the JWT are the three parts of a JWE used to represent the JWT.

The following example JWT Header declares that the encoded object is a JSON Web Token (JWT) and the JWT is signed using the HMAC SHA-256 algorithm:
{"typ":"JWT", "alg":"HS256"}
Base64url encoding the bytes of the UTF-8 representation of the JWT Header yields this Encoded JWS Header value, which is used as the Encoded JWT Header:
eyJ0eXAiOiJKV1QiLA0KICJhbGciOiJIUzI1NiJ9
The following is an example of a JWT Claims Set:
{"iss":"joe", "exp":1300819380, "http://example.com/is_root":true}
Base64url encoding the bytes of the UTF-8 representation of the JSON Claims Set yields this Encoded JWS Payload, which is used as the JWT Second Part (with line breaks for display purposes only):
eyJpc3MiOiJqb2UiLA0KICJleHAiOjEzMDA4MTkzODAsDQogImh0dHA6Ly 9leGFtcGxlLmNvbS9pc19yb290Ijp0cnVlfQ
Signing the Encoded JWS Header and Encoded JWS Payload with the HMAC SHA-256 algorithm and base64url encoding the signature in the manner specified in [JWS] (Jones, M., Balfanz, D., Bradley, J., Goland, Y., Panzer, J., Sakimura, N., and P. Tarjan, “JSON Web Signature (JWS),” December 2011.), yields this Encoded JWS Signature, which is used as the JWT Third Part:
dBjftJeZ4CVP-mB92K27uhbUJU1p1r_wW1gFWFOEjXk
Concatenating these parts in the order Header.Second.Third with period characters between the parts yields this complete JWT (with line breaks for display purposes only):
eyJ0eXAiOiJKV1QiLA0KICJhbGciOiJIUzI1NiJ9 . eyJpc3MiOiJqb2UiLA0KICJleHAiOjEzMDA4MTkzODAsDQogImh0dHA6Ly9leGFt cGxlLmNvbS9pc19yb290Ijp0cnVlfQ . dBjftJeZ4CVP-mB92K27uhbUJU1p1r_wW1gFWFOEjXk
This computation is illustrated in more detail in [JWS] (Jones, M., Balfanz, D., Bradley, J., Goland, Y., Panzer, J., Sakimura, N., and P. Tarjan, “JSON Web Signature (JWS),” December 2011.), Appendix A.1.
| TOC |
The JWT Claims Set represents a JSON object whose members are the claims conveyed by the JWT. The Claim Names within this object MUST be unique. Note however, that the set of claims that a JWT must contain to be considered valid is context-dependent and is outside the scope of this specification. When used in a security-related context, implementations MUST understand and support all of the claims present; otherwise, the JWT MUST be rejected for processing.
There are three classes of JWT Claim Names: Reserved Claim Names, Public Claim Names, and Private Claim Names.
| TOC |
The following claim names are reserved. None of the claims defined in the table below are intended to be mandatory, but rather, provide a starting point for a set of useful, interoperable claims. All the names are short because a core goal of JWTs is for the tokens to be compact.
| Claim Name | JSON Value Type | Claim Syntax | Claim Semantics |
|---|---|---|---|
| exp | number | IntDate | The exp (expiration time) claim identifies the expiration time on or after which the token MUST NOT be accepted for processing. The processing of the exp claim requires that the current date/time MUST be before the expiration date/time listed in the exp claim. Implementers MAY provide for some small leeway, usually no more than a few minutes, to account for clock skew. This claim is OPTIONAL. |
| nbf | number | IntDate | The nbf (not before) claim identifies the time before which the token MUST NOT be accepted for processing. The processing of the nbf claim requires that the current date/time MUST be after or equal to the not-before date/time listed in the nbf claim. Implementers MAY provide for some small leeway, usually no more than a few minutes, to account for clock skew. This claim is OPTIONAL. |
| iat | number | IntDate | The iat (issued at) claim identifies the time at which the JWT was issued. This claim can be used to determine the age of the token. This claim is OPTIONAL. |
| iss | string | StringOrURI | The iss (issuer) claim identifies the principal that issued the JWT. The processing of this claim is generally application specific. The iss value is case sensitive. This claim is OPTIONAL. |
| aud | string | StringOrURI | The aud (audience) claim identifies the audience that the JWT is intended for. The principal intended to process the JWT MUST be identified with the value of the audience claim. If the principal processing the claim does not identify itself with the identifier in the aud claim value then the JWT MUST be rejected. The interpretation of the audience value is generally application specific. The aud value is case sensitive. This claim is OPTIONAL. |
| prn | string | StringOrURI | The prn (principal) claim identifies the subject of the JWT. The processing of this claim is generally application specific. The prn value is case sensitive. This claim is OPTIONAL. |
| jti | string | String | The jti (JWT ID) claim provides a unique identifier for the JWT. The identifier value MUST be assigned in a manner that ensures that there is a negligible probability that the same value will be accidentally assigned to a different data object. The jti claim can be used to prevent the JWT from being replayed. The jti value is case sensitive. This claim is OPTIONAL. |
| typ | string | String | The typ (type) claim is used to declare a type for the contents of this JWT Claims Set. The typ value is case sensitive. This claim is OPTIONAL. |
| Table 1: Reserved Claim Definitions |
Additional reserved claim names MAY be defined via the IANA JSON Web Token Claims registry, as per Section 9 (IANA Considerations). The syntax values used above are defined as follows:
| Syntax Name | Syntax Definition |
|---|---|
| IntDate | The number of seconds from 1970-01-01T0:0:0Z as measured in UTC until the desired date/time. See RFC 3339 (Klyne, G., Ed. and C. Newman, “Date and Time on the Internet: Timestamps,” July 2002.) [RFC3339] for details regarding date/times in general and UTC in particular. |
| String | Any string value MAY be used. |
| StringOrURI | Any string value MAY be used but a value containing a ":" character MUST be a URI as defined in RFC 3986 (Berners-Lee, T., Fielding, R., and L. Masinter, “Uniform Resource Identifier (URI): Generic Syntax,” January 2005.) [RFC3986]. |
| Table 2: Claim Syntax Definitions |
| TOC |
Claim names can be defined at will by those using JWTs. However, in order to prevent collisions, any new claim name SHOULD either be defined in the IANA JSON Web Token Claims registry or be defined as a URI that contains a collision resistant namespace. Examples of collision resistant namespaces include:
In each case, the definer of the name or value needs to take reasonable precautions to make sure they are in control of the part of the namespace they use to define the claim name.
| TOC |
A producer and consumer of a JWT may agree to any claim name that is not a Reserved Name Section 4.1 (Reserved Claim Names) or a Public Name Section 4.2 (Public Claim Names). Unlike Public Names, these private names are subject to collision and should be used with caution.
| TOC |
The members of the JSON object represented by the JWT Header describe the cryptographic operations applied to the JWT and optionally, additional properties of the JWT. The member names within the JWT Header are referred to as Header Parameter Names. These names MUST be unique. The corresponding values are referred to as Header Parameter Values.
Implementations MUST understand the entire contents of the header; otherwise, the JWT MUST be rejected for processing.
There are two ways of distinguishing whether the JWT is a JWS or JWE. The first is by examining the alg (algorithm) header value. If the value represents a signature algorithm, the JWT is a JWS; if it represents an encryption algorithm, the JWT is a JWE. A second method is determining whether an enc (encryption method) member exists. If the enc member exists, the JWT is a JWE; otherwise, the JWT is a JWS. Both methods will yield the same result.
JWS Header Parameters are defined by [JWS] (Jones, M., Balfanz, D., Bradley, J., Goland, Y., Panzer, J., Sakimura, N., and P. Tarjan, “JSON Web Signature (JWS),” December 2011.). JWE Header Parameters are defined by [JWE] (Jones, M., Rescorla, E., and J. Hildebrand, “JSON Web Encryption (JWE),” December 2011.). This specification further specifies the use of the following header parameters in both the cases where the JWT is a JWS and where it is a JWE.
| Header Parameter Name | JSON Value Type | Header Parameter Syntax | Header Parameter Semantics |
|---|---|---|---|
| typ | string | String | The typ (type) header parameter is used to declare structural information about the JWT. In the normal case where nested signing or encryption operations are not employed, the use of this header parameter is OPTIONAL, and if present, it is RECOMMENDED that its value be either "JWT" or "http://openid.net/specs/jwt/1.0". In the case that nested signing or encryption steps are employed, the use of this header parameter is REQUIRED; in this case, the value MUST either be "JWS", to indicate that a nested signed JWT is carried in this JWT or "JWE", to indicate that a nested encrypted JWT is carried in this JWT. |
| Table 3: Reserved Header Parameter Usage |
| TOC |
To support use cases where the JWT content is secured by a means other than a signature and/or encryption contained within the token (such as a signature on a data structure containing the token), JWTs MAY also be created without a signature or encryption. Plaintext JWTs MUST use the alg value none, and are formatted identically to a signed JWT with an empty signature. This means that the base64url encoding of the bytes representing the UTF-8 encoding of the JWT Claims Set is the JWT Second Part, and the empty string is the JWT Third Part.
| TOC |
The following example JWT Header declares that the encoded object is a Plaintext JWT:
{"alg":"none"}
Base64url encoding the bytes of the UTF-8 representation of the JWT Header yields this Encoded JWT Header:
eyJhbGciOiJub25lIn0
The following is an example of a JWT Claims Set:
{"iss":"joe", "exp":1300819380, "http://example.com/is_root":true}
Base64url encoding the bytes of the UTF-8 representation of the JSON Claims Set yields this Encoded JWS Payload, which is used as the JWT Second Part (with line breaks for display purposes only):
eyJpc3MiOiJqb2UiLA0KICJleHAiOjEzMDA4MTkzODAsDQogImh0dHA6Ly9leGFt cGxlLmNvbS9pc19yb290Ijp0cnVlfQ
The JWT Third Part is the empty string.
Concatenating these parts in the order Header.Second.Third with period characters between the parts yields this complete JWT (with line breaks for display purposes only):
eyJhbGciOiJub25lIn0 . eyJpc3MiOiJqb2UiLA0KICJleHAiOjEzMDA4MTkzODAsDQogImh0dHA6Ly9leGFt cGxlLmNvbS9pc19yb290Ijp0cnVlfQ .
| TOC |
To create a JWT, one MUST perform these steps:
When validating a JWT the following steps MUST be taken. If any of the listed steps fails then the token MUST be rejected for processing.
Processing a JWT inevitably requires comparing known strings to values in the token. For example, in checking what the algorithm is, the Unicode string encoding alg will be checked against the member names in the JWT Header to see if there is a matching header parameter name. A similar process occurs when determining if the value of the alg header parameter represents a supported algorithm.
Comparisons between JSON strings and other Unicode strings MUST be performed as specified below:
| TOC |
JWTs use JSON Web Signature (JWS) [JWS] (Jones, M., Balfanz, D., Bradley, J., Goland, Y., Panzer, J., Sakimura, N., and P. Tarjan, “JSON Web Signature (JWS),” December 2011.) and JSON Web Encryption (JWE) [JWE] (Jones, M., Rescorla, E., and J. Hildebrand, “JSON Web Encryption (JWE),” December 2011.) to sign and/or encrypt the contents of the JWT.
Of the JWS signing algorithms, only HMAC SHA-256 MUST be implemented by conforming JWT implementations. It is RECOMMENDED that implementations also support the RSA SHA-256 and ECDSA P-256 SHA-256 algorithms. Support for other algorithms and key sizes is OPTIONAL.
If an implementation provides encryption capabilities, of the JWE encryption algorithms, only RSA-PKCS1-1.5 with 2048 bit keys, AES-128-CBC, and AES-256-CBC MUST be implemented by conforming implementations. It is RECOMMENDED that implementations also support ECDH-ES with 256 bit keys, AES-128-GCM, and AES-256-GCM. Support for other algorithms and key sizes is OPTIONAL.

TBD: Lots of work to do here. We need to remember to look into any issues relating to security and JSON parsing. One wonders just how secure most JSON parsing libraries are. Were they ever hardened for security scenarios? If not, what kind of holes does that open up? Also, we need to walk through the JSON standard and see what kind of issues we have especially around comparison of names. For instance, comparisons of claim names and other parameters must occur after they are unescaped. Need to also put in text about: Importance of keeping secrets secret. Rotating keys. Strengths and weaknesses of the different algorithms.
TBD: Need to put in text about why strict JSON validation is necessary. Basically, that if malformed JSON is received then the intent of the sender is impossible to reliably discern. One example of malformed JSON that MUST be rejected is an object in which the same member name occurs multiple times. While in non-security contexts it's o.k. to be generous in what one accepts, in security contexts this can lead to serious security holes. For example, malformed JSON might indicate that someone has managed to find a security hole in the issuer's code and is leveraging it to get the issuer to issue "bad" tokens whose content the attacker can control.
TBD: Write about the need to secure the token content if a signature is not contained in the JWT itself.
| TOC |
Claim names in JWTs are Unicode strings. For security reasons, the representations of these names must be compared verbatim after performing any escape processing (as per RFC 4627 (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627], Section 2.5).
This means, for instance, that these JSON strings must compare as being equal ("JWT", "\u004aWT"), whereas these must all compare as being not equal to the first set or to each other ("jwt", "Jwt", "JW\u0074").
JSON strings MAY contain characters outside the Unicode Basic Multilingual Plane. For instance, the G clef character (U+1D11E) may be represented in a JSON string as "\uD834\uDD1E". Ideally, JWT implementations SHOULD ensure that characters outside the Basic Multilingual Plane are preserved and compared correctly; alternatively, if this is not possible due to these characters exercising limitations present in the underlying JSON implementation, then input containing them MUST be rejected.

The following items remain to be done in this draft:

SAML 2.0 (Cantor, S., Kemp, J., Philpott, R., and E. Maler, “Assertions and Protocol for the OASIS Security Assertion Markup Language (SAML) V2.0,” March 2005.) [OASIS.saml‑core‑2.0‑os] provides a standard for creating tokens with much greater expressivity and more security options than supported by JWTs. However, the cost of this flexibility and expressiveness is both size and complexity. In addition, SAML's use of XML (Cowan, J., “Extensible Markup Language (XML) 1.1,” October 2002.) [W3C.CR‑xml11‑20021015] and XML DSIG (Eastlake, D., Reagle, J., and D. Solo, “(Extensible Markup Language) XML-Signature Syntax and Processing,” March 2002.) [RFC3275] only contributes to the size of SAML tokens.
JWTs are intended to provide a simple token format that is small enough to fit into HTTP headers and query arguments in URIs. It does this by supporting a much simpler token model than SAML and using the JSON (Crockford, D., “The application/json Media Type for JavaScript Object Notation (JSON),” July 2006.) [RFC4627] object encoding syntax. It also supports securing tokens using Hash-based Message Authentication Codes (HMACs) and digital signatures using a smaller (and less flexible) format than XML DSIG.
Therefore, while JWTs can do some of the things SAML tokens do, JWTs are not intended as a full replacement for SAML tokens, but rather as a compromise token format to be used when space is at a premium.

Both JWTs and Simple Web Tokens SWT (Hardt, D. and Y. Goland, “Simple Web Token (SWT),” November 2009.) [SWT], at their core, enable sets of claims to be communicated between applications. For SWTs, both the claim names and claim values are strings. For JWTs, while claim names are strings, claim values can be any JSON type. Both token types offer cryptographic protection of their content: SWTs with HMAC SHA-256 and JWTs with a choice of algorithms, including HMAC SHA-256, RSA SHA-256, and ECDSA P-256 SHA-256.
| TOC |
The authors acknowledge that the design of JWTs was intentionally influenced by the design and simplicity of Simple Web Tokens (Hardt, D. and Y. Goland, “Simple Web Token (SWT),” November 2009.) [SWT] and ideas for JSON tokens that Dick Hardt discussed within the OpenID community.
Solutions for signing JSON content were previously explored by Magic Signatures (Panzer (editor), J., Laurie, B., and D. Balfanz, “Magic Signatures,” August 2010.) [MagicSignatures], JSON Simple Sign (Bradley, J. and N. Sakimura (editor), “JSON Simple Sign,” September 2010.) [JSS], and Canvas Applications (Facebook, “Canvas Applications,” 2010.) [CanvasApp], all of which influenced this draft.

Video Feeds
Managing Video Feeds
Managing video feeds is done by accessing the Videos > Video Feeds > Search Feeds function in the control panel menu.
From this interface you can add new video feeds and search, edit, or delete the existing video feeds. For an overview of searching,
adding, editing, and deleting items, please see the Control Panel Basics section of this software manual.
Database Fields
Video Feeds have the following fields associated with them:
Individual Functions
-
Feed Name - A name for the feed, for easier identification
Feed URL - The full URL to the feed
Feed Type - The type of feed. The following feed types are supported:
XML Videos Feed
This is a feed that meets this specification. These types of
feeds are often offered by adult sponsors. A list of sponsors that offer these feeds is maintained in the
TubeX forum.
When videos are imported from this type of feed, the actual video clips will be hotlinked from the remote server so it won't use any of your bandwidth. The preview thumbnail images will be downloaded to your server, resized if possible, and used as the preview images for this video.
YouTube
This is a feed that uses the YouTube Data API.
Videos imported from a YouTube feed will use the embed code provided by YouTube. This will display the YouTube player, and the video will be loaded from
YouTube's servers so it won't use your bandwidth.
The preview thumbnail images for the video will be downloaded to your server and used as the preview images for imported videos.
Sponsor - The sponsor associated with this feed. All videos imported from this feed will be assigned this sponsor.
Category - The default category to use for videos imported from this feed. Videos which cannot be categorized using the Automatic Categorization feature will be assigned to this category.
Username - The username to set for videos imported from this feed
Status - The status to set for videos imported from this feed
Comments Allowed - Indicates if comments are allowed for this video
Allow ratings - Indicates if ratings are allowed for this video
Allow embedding - Indicates if this video can be embedded in remote sites
Make private - Set videos imported from this feed as private
Besides the Common Functions available for most items, video feeds also have some custom functions that can be run. The icons that appear for each
video feed in the Search Feeds interface are described below.
-
- Click this to have the software read the feed and import the videos it finds in the feed. The software will keep track of what videos
were imported from each feed to prevent duplicates from being imported. Because of this, it will not be too uncommon to receive a message
that 0 videos were imported from the feed when running this function.
- Click this icon to test the feed. This will check that a valid feed URL was provided, and that the feed is a valid feed of the type you selected.

Information
Updating the API only updates the access and expiration date.
So modifications from Character to Account or visa versa will still cause problems.
This will be solved soon.
For better functionality and faster responses, parts of the API data will be saved to the database.  If you want to see exactly what I save and how it is used. Please take a look at my source code
For more questions feel free to contact Ghitzarai ingame.

Experience with the x-kom company app
Hi all,
The x-kom is a company which everyone know.
Currently, they are one of the biggest retailers of electronic articles in Poland.
A few weeks ago I looked closer at the mobile application for Android and iOS operating systems.
I found 3 bugs in both applications.
- In the first issue, I can not add the article to the cart when I am not sign in.
- In the second, the price from which is discount is equaled 0.00.
- In the third, not all articles have information about sold amounts.
– Articles sorted ascending
– Articles sorted descending
I sent the request with the screenshots to x-kom via e-mail.
I received only information about the received request,
and no message about fixed function.
The life went forward and sometime after sent request, the mobile applications for both operating systems received updates.
After these updates, I got something from x-kom - they changed the minimal version of iOS from 12.0 to 13.0.
So, now I can’t get access via an application from my iPhone 5S - but Apple still publish security updates,
so I can think this model is still supported.
Also, I do not understand one thing:
if they do not allow me to have access to the store - why they still sent a push notification to me about new promotions?
It is everything that I have for today.
Everyone is a blacksmith of own fate.
Mateusz.


Customized browser interface with fallback
When developing a more customized file input interface, we can apply a fallback for browsers, such as IE8 and IE9, that do not support the HTML5 File API.
The new fallback interface is a simple alternative that can then be styled with custom CSS and help maintain a consitent branding on the site, even if the browser does not support modern behavior.

In the last week of the JavaScript course by OneMonth, Google Charts was introduced as a way to include, you guessed it, charts on a website using JavaScript and Google's Charts API. Below is a chart depicting the average IMDb scores of movies from individual years. The data used for that was a dataset from kaggle.com.
You can also hover over the line chart to see what the exact average score was for movies released in that year. Please note that it is not certain, whether the dataset contains all of the movies on IMDb, but my guess is probably not.

Police release sketch of child whose remains were found at Delaware softball field
by Isabel Hughes, Delaware News JournalWILMINGTON, Del. – A sketch of the young girl whose remains were found at a softball field in Delaware in September was released this week by authorities to help solve the mystery of her death.
Smyrna Police Department investigators said they hope the facial reconstruction sketches prompt tipsters to come forward with either the girl's identity or possible suspect information.
The department is working with the National Center for Missing and Exploited Children and the Delaware Division of Forensic Science on the case.
Police were first called to the Little Lass softball fields, which are across the road from Smyrna Middle School, at about 4:30 p.m. on Sept. 13 after a person who was walking a dog noticed the remains, Delaware Online/The News Journal previously reported.
Though police released little information at the time, they now say they believe the girl, who was likely Caucasian or Hispanic, was 2 to 5 years old.
Missing girl: South Carolina police find remains of 5-year-old girl in landfill
She had slightly wavy brown hair, and an "anthropological exam of her remains suggests that she suffered from chronic illness(es)," police said.
Investigators believe she was dead for "several weeks or possibly longer" before she was found.
The softball league that operates the fields where the remains were found said at the time that it was "deeply saddened and disturbed by this news."

207. Robbers
time limit per test: 2 sec.
memory limit per test: 65536
KB
input: standard
output: standard
N robbers have robbed the bank. As the result of their crime
they chanced to get M golden coins. Before the robbery the band has made an
agreement that after the robbery i-th gangster would get Xi/Y of all
money gained. However, it turned out that M may be not divisible by Y.
The problem which now should be solved by robbers is what to do with the
coins. They would like to share them fairly. Let us suppose that i-th robber
would get Ki coins. In this case unfairness of this fact is
|Xi/Y-Ki/M|. The total unfairness is the sum of all
particular unfairnesses. Your task as the leader of the gang is to spread money
among robbers in such a way that the total unfairness is minimized.
Input
The first line of the input file contains numbers N, M and Y (1
≤ N ≤ 1000, 1 ≤ M, Y ≤ 10000). N integer numbers follow - Xi (1 ≤
Xi ≤ 10000, sum of all Xi is Y).
Output
Output N integer numbers — Ki (sum of all
Ki must be M), so that the total unfairness is minimal.

- If you are not using Alternate Status, Digital Output or Drive Address registers pins cs1 & cs0 can be saved by connecting these ide pins to cs0-high, cs1-low at ide connector. normal operation does not require these pins. Set "CONST BYTE PATA_HD_USE_CS0_CS1_PINS = TRUE" if you will be using these registers - You MUST write full sectors of 512 bytes. - this lib does not do error checking

Please ask questions
- Questions are welcome throughout
Overview
- Controller/Action method testing
- Then, transition to new ASP.NET Core Testing features
- TestHost/WebApplicationFactory
- Mostly sample code and demos
Testing Terminology
- Lots of testing terms - unit vs integration, etc.
- This presentation will cover my own term, "Automated Developer testing"
- Developer Testing - automated tests run often by Developer, while coding, typically from their IDE.
Traditional Testing
- MVC controllers are C# classes
- In a test, construct the controller, test the action methods.
Traditional Testing - Problems?
- Misses anything that happens before or after the action method of controller.
- Action or controller attributes - e.g. Routing, Authorize attributes
- Response codes, response formatting
- Request parsing
- Dependency Injection configuration
Traditional Testing - Demo
New ASP.Net Core Testing Features
- 1.x - TestServer
- 2.x - WebApplicationFactory - helper method around TestServer
- TestServer - in-memory version of entire ASP.Net Core Server, with connected HttpClient instance.
- Full stack executes, middleware, routing, authorization, model binding, DI, etc.
More Demos
- Middleware Testing
- Authorization Testing
- View Testing (e.g. result of .cshtml executing)

Lexical analyzer generator for Erlang.
A regular expression based lexical analyzer generator for Erlang, similar to lex or flex.
ScanRet = {ok,Tokens,EndLine} | {eof,EndLine} | {error,ErrorDescriptor,EndLine} Cont = continuation() ErrorDescriptor = {ErrorLine,Module,Error}
file(FileName) -> ok | error file(FileName, Options) -> ok | error
The current options are:
{outdir,Dir} - generate the scanner file in directory Dir dfa_graph - generate a .dot file which contains a desciption of the DFA in a format which can be viewd with Graphviz, www.graphviz.com
Generate a lexical analyzer from the definition in the input file. The input file has the extension .xrl. This is added to the filename if it is not given. The resulting module is the Xrl filename without the .xrl extension.
string(String) -> ScanRet string(String, StartLine) -> ScanRet
Scan String and return all the tokens in it, or an error. N.B. it is an error if all of the characters in String are consumed.
token(Cont, Chars) -> {more,Cont} | {done,ScanRet,RestChars} token(Cont, Chars, StartLine) -> {more,Cont} | {done,ScanRet,RestChars}
This is a re-entrant call to try and scan one token from Chars. If there are enough characters in Chars to either scan a token or detect an error then this will be returned with {done,...}. Otherwise {cont,Cont} will be returned where Cont is used in the next call to token with more characters to try an scan the token. This is continued until a token has been scanned. Cont is initially [].
It is not designed to be called directly by an application but used through the i/o system where it can typically called in an application by:
io:request(InFile, {get_until,Prompt,Module,token,[Line]}) -> ScanRet
tokens(Cont, Chars) -> {more,Cont} | {done,ScanRet,RestChars} tokens(Cont, Chars, StartLine) -> {more,Cont} | {done,ScanRet,RestChars}
This is a re-entrant call to try and scan tokens from Chars. If there are enough characters in Chars to either scan tokens or detect an error then this will be returned with {done,...}. Otherwise {cont,Cont} will be returned where Cont is used in the next call to tokens with more characters to try an scan the tokens. This is continued until all tokens have been scanned. Cont is initially [].
This functions differs from token in that it will continue to scan tokens upto and including an {end_token,Token} has been scanned (see next section). It will then return all the tokens. This is typically used for scanning grammars like Erlang where there is an explicit end token, '.'. If no end token is found then the whole file will be scanned and returned. If an error occurs then all tokens upto and including the next end token will be skipped.
It is not designed to be called directly by an application but used through the i/o system where it can typically called in an application by:
io:request(InFile, {get_until,Prompt,Module,tokens,[Line]}) -> ScanRet
format_error(ErrorDescriptor) -> Chars
Types:
ErrorDescriptor = errordesc() Chars = [char() | Chars]
Returns a string which describes the error ErrorDescriptor returned when there is an error in a regular expression.
Erlang style comments starting with a '%' are allowed in scanner files. A definition file has the following format:
<Header>
Definitions.
<Macro Definitions>
Rules.
<Token Rules>
Erlang Code.
<Erlang Code>
The "Definitions.", "Rules." and "Erlang Code." headings are mandatory and must occur at the beginning of a source line. The <Header>, <Macro Definitions> and <Erlang Code> sections maybe empty but there must be at least one rule.
Macro definitions have the following format:
NAME = VALUE
and there must be spaces around '='. Macros can be used in the regular expressions of rules by writing {NAME}. N.B. when macros are expanded in expressions the macro calls are replaced by the macro value without any form of quoting or enclosing in parentheses.
Rules have the following format:
<Regexp> : <Erlang code>.
The <Regexp> must occur at the start of a line and not include any blanks, use \t and \s to include TAB and SPACE characters in the regular expression. If <Regexp> matches then the corresponding <Erlang code> is evaluated to generate a token. With the Erlang code the following predefined variables are available:
TokenChars - a list of the characters in the matched token TokenLen - the number of characters in the matched token TokenLine - the line number where the token occured
The code must return:
{token,Token} - return Token to the caller {end_token,Token} - return Token and is last token in a tokens call skip_token - skip this token completely {error,ErrString} - an error in the token, ErrString is a string describing the error
The following example would match a simple Erlang integer or float and return a token which could be sent to the Erlang parser:
D = [0-9]
{D}+ : {token,{integer, TokenLine, list_to_integer(TokenChars)}}. {D}+\.{D}+((E|e)(\+|\-)?{D}+)? : {token,{float,TokenLine,list_to_float(TokenChars)}}.
The Erlang code in the "Erlang Code." section is written into the output file directly after the module declaration and predefined exports declaration so it is possible to add extra exports, define imports and other attributes which are then visible in the whole file.
The regular expressions allowed here is a subset of the set found in egrep and in the AWK programming language, as defined in the book, The AWK Programming Language, by A. V. Aho, B. W. Kernighan, P. J. Weinberger. They are composed of the following characters:
c matches the non-metacharacter c. \c matches the escape sequence or literal character c. . matches any character. ^ matches the beginning of a string. $ matches the end of a string. [abc...] character class, which matches any of the characters abc... Character ranges are specified by a pair of characters separated by a -. [^abc...] negated character class, which matches any character except abc.... r1 | r2 alternation. It matches either r1 or r2. r1r2 concatenation. It matches r1 and then r2. r+ matches one or more rs. r* matches zero or more rs. r? matches zero or one rs. (r) grouping. It matches r.
The escape sequences allowed are the same as for Erlang strings:
\b backspace \f form feed \n newline (line feed) \r carriage return \t tab \e escape \v vertical tab \s space \d delete \ddd the octal value ddd \c any other character literally, for example \\ for backslash, \" for ")
The following examples define Erlang data types:
Atoms [a-z][0-9a-zA-Z_]*
Variables [A-Z_][0-9a-zA-Z_]*
Floats (\+|-)?[0-9]+\.[0-9]+((E|e)(\+|-)?[0-9]+)?
N.B. Anchoring a regular expression with ^ and $ is not implemented in the current version of leex and just generates a nasty error.Generated by EDoc, Aug 9 2008, 16:53:08.
