Adds two rendering options.
This syntax skips all template overrides and goes directly to the provided ActiveScaffold templates. Useful if you want to wrap an existing template. Just call super!
Lets you embed an ActiveScaffold by referencing the controller where it‘s configured.
You may specify options[:constraints] for the embedded scaffold. These constraints have three effects:
* the scaffold's only displays records matching the constraint * all new records created will be assigned the constrained values * constrained columns will be hidden (they're pretty boring at this point)
You may also specify options[:conditions] for the embedded scaffold. These only do 1/3 of what constraints do (they only limit search results). Any format accepted by ActiveRecord::Base.find is valid.
Defining options[:label] lets you completely customize the list title for the embedded scaffold.


Recently I was working in a project that used a custom PasswordEncoder
and there was a requirement to migrate it to
bcrypt. The current passwords are stored as hash
which means it’s not
possible to revert it to the original String
- at least not in an easy way.
The challenge here was how to support both implementations, the old hash solution along with the new bcrypt
implementation. After a little research I could find Spring Security 5’s
DelegatingPasswordEncoder
.
Meet DelegatingPasswordEncoder
The DelegatingPasswordEncoder
class makes it possible to support multiple password encoders
based on a prefix. The
password is stored like this:
{bcrypt}$2a$10$vCXMWCn7fDZWOcLnIEhmK.74dvK1Eh8ae2WrWlhr2ETPLoxQctN4.
{noop}plaintextpassword
Spring Security 5 brings the handy PasswordEncoderFactories
class,
currently this class supports the following encoders:
public static PasswordEncoder createDelegatingPasswordEncoder() {
String encodingId = "bcrypt";
Map<String, PasswordEncoder> encoders = new HashMap<>();
encoders.put(encodingId, new BCryptPasswordEncoder());
encoders.put("ldap", new org.springframework.security.crypto.password.LdapShaPasswordEncoder());
encoders.put("MD4", new org.springframework.security.crypto.password.Md4PasswordEncoder());
encoders.put("MD5", new org.springframework.security.crypto.password.MessageDigestPasswordEncoder("MD5"));
encoders.put("noop", org.springframework.security.crypto.password.NoOpPasswordEncoder.getInstance());
encoders.put("pbkdf2", new Pbkdf2PasswordEncoder());
encoders.put("scrypt", new SCryptPasswordEncoder());
encoders.put("SHA-1", new org.springframework.security.crypto.password.MessageDigestPasswordEncoder("SHA-1"));
encoders.put("SHA-256", new org.springframework.security.crypto.password.MessageDigestPasswordEncoder("SHA-256"));
encoders.put("sha256", new org.springframework.security.crypto.password.StandardPasswordEncoder());
return new DelegatingPasswordEncoder(encodingId, encoders);
}
Now instead of declaring a single PasswordEncoder
we can use the PasswordEncoderFactories
, like this snippet of code:
@Bean
public PasswordEncoder passwordEncoder() {
return PasswordEncoderFactories.createDelegatingPasswordEncoder();
}
Adding a Custom Encoder
Now, getting back to my initial problem, for legacy reasons there is a homegrown password encoding
solution, and the
handy PasswordEncoderFactories
knows nothing about it, to solve that I’ve created a class similar to the
PasswordEncoderFactories
and I’ve added all the built-in encoders along with my custom one, here’s a sample implementation:
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.DelegatingPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.crypto.password.Pbkdf2PasswordEncoder;
import org.springframework.security.crypto.scrypt.SCryptPasswordEncoder;
import java.util.HashMap;
import java.util.Map;
class DefaultPasswordEncoderFactories {
@SuppressWarnings("deprecation")
static PasswordEncoder createDelegatingPasswordEncoder() {
String encodingId = "bcrypt";
Map<String, PasswordEncoder> encoders = new HashMap<>();
encoders.put(encodingId, new BCryptPasswordEncoder());
encoders.put("ldap", new org.springframework.security.crypto.password.LdapShaPasswordEncoder());
encoders.put("MD4", new org.springframework.security.crypto.password.Md4PasswordEncoder());
encoders.put("MD5", new org.springframework.security.crypto.password.MessageDigestPasswordEncoder("MD5"));
encoders.put("noop", org.springframework.security.crypto.password.NoOpPasswordEncoder.getInstance());
encoders.put("pbkdf2", new Pbkdf2PasswordEncoder());
encoders.put("scrypt", new SCryptPasswordEncoder());
encoders.put("SHA-1", new org.springframework.security.crypto.password.MessageDigestPasswordEncoder("SHA-1"));
encoders.put("SHA-256", new org.springframework.security.crypto.password.MessageDigestPasswordEncoder("SHA-256"));
encoders.put("sha256", new org.springframework.security.crypto.password.StandardPasswordEncoder());
encoders.put("custom", new CustomPasswordEncoder());
return new DelegatingPasswordEncoder(encodingId, encoders);
}
}
And then I declared my @Bean
using the DefaultPasswordEncoderFactories
instead.
After my first run I realized another problem, I would have to run a SQL
script to update all the existing passwords
adding the {custom}
prefix so the framework could properly bind the prefix with the right PasswordEncoder
,
don’t get me wrong it’s an fine solution but I really did not want to mess around with existing passwords in the
database and luckily for us the DelegatingPasswordEncoder
class allows us to set a default PasswordEncoder
, it means
whenever the framework tries doesn’t find a prefix in the stored password it will fallback to the default
one to try
to decode it.
Then I changed my implementation to the following:
import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;
import org.springframework.security.crypto.password.DelegatingPasswordEncoder;
import org.springframework.security.crypto.password.PasswordEncoder;
import org.springframework.security.crypto.password.Pbkdf2PasswordEncoder;
import org.springframework.security.crypto.scrypt.SCryptPasswordEncoder;
import java.util.HashMap;
import java.util.Map;
class DefaultPasswordEncoderFactories {
@SuppressWarnings("deprecation")
static PasswordEncoder createDelegatingPasswordEncoder() {
String encodingId = "bcrypt";
Map<String, PasswordEncoder> encoders = new HashMap<>();
encoders.put(encodingId, new BCryptPasswordEncoder());
encoders.put("ldap", new org.springframework.security.crypto.password.LdapShaPasswordEncoder());
encoders.put("MD4", new org.springframework.security.crypto.password.Md4PasswordEncoder());
encoders.put("MD5", new org.springframework.security.crypto.password.MessageDigestPasswordEncoder("MD5"));
encoders.put("noop", org.springframework.security.crypto.password.NoOpPasswordEncoder.getInstance());
encoders.put("pbkdf2", new Pbkdf2PasswordEncoder());
encoders.put("scrypt", new SCryptPasswordEncoder());
encoders.put("SHA-1", new org.springframework.security.crypto.password.MessageDigestPasswordEncoder("SHA-1"));
encoders.put("SHA-256", new org.springframework.security.crypto.password.MessageDigestPasswordEncoder("SHA-256"));
DelegatingPasswordEncoder delegatingPasswordEncoder = new DelegatingPasswordEncoder(encodingId, encoders);
delegatingPasswordEncoder.setDefaultPasswordEncoderForMatches(new CustomPasswordEncoder());
return delegatingPasswordEncoder;
}
}
And the @Bean
declaration is now:
@Bean
public PasswordEncoder passwordEncoder() {
return DefaultPasswordEncoderFactories.createDelegatingPasswordEncoder();
}
Conclusion
Migration password encoders is a real life problem and Spring Security 5
gives a quite handy way to easily handle it by supporting multiple PasswordEncoder
s at once.

Picture books
The Snatchabook by Helen and Thomas Doherty
Eliza, a young rabbit, discovers the funny little creature who has been stealing her books. In a remarkable act of generosity, she offers to read him a nightly bedtime story so he can forsake his life of crime whilst still enjoying books. Now if there had been a public library in Eliza’s wood, the Snatchabook could have joined, borrowed all the books he could read for free and gone along to storytimes and Tot Rock too.
A library book for Bear by Bonny Becker
Bear has 7 books already, so why does he need to go the library? When he gets there (cajoled by his friend Mouse) he overhears a story time and is seduced. Bonny Becker’s other picture books about Bear and Mouse are well worth hunting out if you haven’t come across them before. We have them all because we are a library, and you may borrow them for free, just like Bear. This paperback edition came out in November 2015.
Wolves by Emily Gravett
Now we were very pleased to see Emily Gravett’s masterpiece about the book loving rabbit reissued last year for its 10th anniversary. However, if you are of a squeamish disposition, you may not be as pleased as we were, and may not want to find out what happens to the poor little rabbit when the wolves in his library book come alive.
Sarah and Duck at the library by Sarah Gomes Harris
We really wish the librarian in this story didn’t say “Shhhhh!” (none of the staff in Suffolk Libraries would ever say such a thing) but we know all those Sarah and Duck enthusiasts will not unable to resist borrowing this cute little book, so we bought lots of copies.
How the library (not the prince) saved Rapunzel by Wendy Meddour
Now published in paperback, this rather bored Rapunzel is still looking out the window of her 16th floor flat. She refuses to cheer up or marry, but when a job offer arrives from the local library, her mood lightens and her life becomes busy and interesting.

Authentication
Documentation
LearningStudio API Authentication can be tricky at first. We recommend you read up on our Authentication Concepts in the documentation.
API Keys
You will need keys to work with the APIs.
- Application ID: Identifies your Application for analytics and quota limits.
- Campus Keys: A Token Key Moniker (TKM), Shared Secret, and Client String identifies the LearningStudio campus where your data comes from.
You can get an Application ID for your app and campus keys for our Sandbox Campus by creating an app on the PDN. Learn more here.
Contents
Background Information
There are two main use cases for Authentication: System-to-System API calls, and API calls on behalf of a user.
System-to-System calls are most often used by administration systems that are looking up or processing changes for many courses or users at once. For example, retrieving a course roster or all the grades for a course, or many grade updates. These don't require a user context, and for these we use OAuth 1.0a. With OAuth 1, every request is signed individually, and the signature is compared by LearningStudio to ensure you have permission to access that data. Not all APIs are enabled for system-to-system requests.
API Calls on behalf of Users are made when you need to perform an action that should be associated to a user in LearningStudio such as posting a thread discussion, retrieving the content a student is permitted to see, submitting homework, etc. For these requests, we use OAuth 2, where you will generate a token for that user and send the token with every request in an HTTP header.
To get a token in OAuth 2, you have two options. First, if you are able to collect the user's password, you can use the Password grant type. If you don't know the user's password, you can use an Assertion grant type which generates a token request using only the user's username and the campus keys. This library, especially when combined with Core, simplifies this work.
Lastly, our Authentication schemes both require the use of a CMAC-AES algorithm for generating the appropriate signature. This algorithm is more obscure than most, so this library handles the cryptography heavy lifting.
Using Authentication
OAuth 1 (System to System)
Setup
To begin, include the classes you'll be instantiating.
using Com.Pearson.Pdn.Learningstudio.OAuth;
using Com.Pearson.Pdn.Learningstudio.OAuth.Config;
using Com.Pearson.Pdn.Learningstudio.OAuth.Request;
using Com.Pearson.Pdn.Learningstudio.Utility;
Configuration
In OAuth 1, you need your Application ID, Token Key Moniker and Secret. In the OAuth 1.0a standard, the TKM and secret are called the Consumer Key and Consumer Secret.
The OAuthConfig
class is a generic carrier for the configuration information for all authentication methods. You'll add the three keys you need using these methods:
OAuthConfig config = new OAuthConfig();
config.ApplicationId = {applicationId};
config.ConsumerKey = {tokenKeyMonikder};
config.ConsumerSecret = {sharedSecret};
The Factory
The OAuthServiceFactory
object instantiates an appropriate service for the authentication method you want to use. With this approach, you need only use the factory object and tell it which auth method you want to use, and it returns an object that will handle the signature generation. When creating the factory object, pass the config object to the constructor:
OAuthServiceFactory oauthFactory = new OAuthServiceFactory(config);
OAuth1SignatureService oauthService = oauthFactory.Build<OAuth1SignatureService>(typeof(OAuth1SignatureService));
Signature Generation
In this example, oauthService
is an object of the OAuth1SignatureService
class. This object will take the configuration information and the details of the API request you'll be making, and generates a signature. In OAuth 1, every API call is individually signed, so you always pass it the URI of the endpoint you're calling.
The method you will use to generate the signature is generateOAuth1Request
method, which has the following signature:
GenerateOAuth1Request(Com.Pearson.Pdn.Learningstudio.Utility.HttpMethod httpMethod, Uri url, string body )
| Parameter | Description |
|---|---|
httpMethod |
An enumeration of the standard HTTP Methods GET , POST , PUT , or DELETE ; implemented by the Com.Pearson.Pdn.Learningstudio.Utility class. Required for all requests. |
url |
The URL of the API endpoint you're calling. Required for all requests. |
body |
The body of the API request. Required for POST and PUT operations only. Otherwise, an empty string value should be given. |
Results
When you call the GenerateOAuth1Request
method, it will return an object of the OAuth1Request
class. This object has two properties:
| Property | Description |
|---|---|
IDictionary<string,string> Headers |
The full HTTP header to include in your API call. They are returned as key value pairs in a IDictionary<string,string> collection. These headers are ready to use, you don't need to encode any values. Example: X-Authorization: OAuth realm="... |
string Signature |
The signature that was generated, in an unencoded form. If you are building your own HTTP header for the request, be sure to base64-encode this value before using it. Example: n55cLjl02ejAJCEV1QTnvg== |
Example
using Com.Pearson.Pdn.Learningstudio.OAuth;
using Com.Pearson.Pdn.Learningstudio.OAuth.Config;
using Com.Pearson.Pdn.Learningstudio.OAuth.Request;
using Com.Pearson.Pdn.Learningstudio.Utility;
using System;
using System.Collections.Generic;
using System.Net;
namespace OAuth1Example
{
class Program
{
static void Main(string[] args)
{
string applicationId = ""; // Identifies your Application
string tokenKeyMonikder = ""; // Called "Consumer Key" in OAuth 1 standard
string sharedSecret = ""; // Called "Consumer Secret" in OAuth 1 standard
Uri url = new Uri(""); // e.g., https://api.learningstudio.com/users/{userId}
OAuthConfig config = new OAuthConfig();
config.ApplicationId = applicationId;
config.ConsumerKey = tokenKeyMonikder;
config.ConsumerSecret = sharedSecret;
OAuthServiceFactory oauthFactory = new OAuthServiceFactory(config);
OAuth1SignatureService oauthService = oauthFactory.Build<OAuth1SignatureService>(typeof(OAuth1SignatureService));
// If using POST or PUT, also send the body in the third parameter:
OAuth1Request oauthRequest = oauthService.GenerateOAuth1Request(HttpMethod.GET, url, string.Empty);
IDictionary<string,string> oauthHeaders = oauthRequest.Headers;
// Returns HTTP Header key and value pairs
// ready to use in your API Call, e.g.
// X-Authroization: OAuth realm="...
string signatureOnly = oauthRequest.Signature;
// Returns the unencoded signature value, e.g.
// n55cLjl02ejAJCEV1QTnvg==
/* Using the HTTP Header */
HttpWebRequest httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url);
httpWebRequest.Method = "GET";
foreach (string oauthHeaderKey in oauthHeaders.Keys)
httpWebRequest.Headers[oauthHeaderKey] = oauthHeaders[oauthHeaderKey];
HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse();
Console.WriteLine("Status Code: {0}", (int)httpWebResponse.StatusCode);
Console.ReadLine();
}
}
}
OAuth 2 (Password Grant Type)
Setup
To begin, include the classes you'll be instantiating.
using Com.Pearson.Pdn.Learningstudio.OAuth;
using Com.Pearson.Pdn.Learningstudio.OAuth.Config;
using Com.Pearson.Pdn.Learningstudio.OAuth.Request;
Configuration
In OAuth 2 Password Grant Type, you need your Application ID, and Client String.
The OAuthConfig
class is a generic carrier for the configuration information for all authentication methods. You'll add the two keys you need using these methods:
OAuthConfig config = new OAuthConfig();
config.ApplicationId = {applicationID};
config.ClientString = {clientString};
The Factory
The OAuthServiceFactory
object instantiates an appropriate service for the authentication method you want to use. With this approach, you need only use the factory object and tell it which auth method you want to use, and it returns an object that will handle the access token generation. When creating the factory object, pass the config object to the constructor:
OAuthServiceFactory oauthFactory = new OAuthServiceFactory(config);
OAuth2PasswordService oauthService = oauthFactory.Build<OAuth2PasswordService>(typeof(OAuth2PasswordService));
Token Request
In this example, oauthService
is an object of the OAuth2PasswordService
class. This object will take the configuration information and the username and password, and requests an access token for the user. Use the token in an HTTP Header for all subsequent requests. The token lasts an hour, after which time you can use the refresh token to get a new access token without requiring the user to sign in again.
The method you will use to request the token is GenerateOAuth2PasswordRequest
method, which has the following signature:
GenerateOAuth2PasswordRequest(string username, string password )
Results
When you call the GenerateOAuth2PasswordService
method, it will return an object of the OAuth2Request
class. This object has several properties:
| Property | Description |
|---|---|
IDictionary<string,string> Headers |
The full HTTP header to include in your API call. They are returned as key value pairs in a IDictionary<string,string> collection. These headers are ready to use, you don't need to encode any values. Example: X-Authorization: Access_Token access_token="... |
string AccessToken |
Only the access token that was generated. |
string RefreshToken |
The refresh token that was generated along with the access token. |
long? ExpirationTime |
The Unix timestamp of when the token will expire. |
long? CreationTime |
Returns the Unix timestamp of when the token was generated. |
int? ExpiresInSeconds |
Returns the lifespan in seconds of the token. This is always set to 3600. |
Refresh Token
When using the Password grant type workflow, you can get a new token for the user by using the refresh token, instead of having the user sign in again after an hour. The refresh token only lasts about 5-10 minutes longer, so you'll need to use it soon after the access token expires. To generate a new access token using a refresh token, use the RefreshOAuth2PasswordRequest
method of the OAuth service. Pass this method the OAuth2Request
object that the service provided you (see previous section):
RefreshOAuth2PasswordRequest(OAuth2Request oauthRequest)
The service will return a new OAuth2Request
object described in the results section above.

OAuthConfig config = new OAuthConfig();
config.ApplicationId = applicationId;
config.ClientString = clientString;

OAuth2PasswordService oauthService = oauthFactory.Build<OAuth2PasswordService>(typeof(OAuth2PasswordService));
// If using POST or PUT, also send the body in the third parameter:

IDictionary<string, string> oauthHeaders = oauthRequest.Headers;
// Returns HTTP Header key and value pairs
// ready to use in your API Call, e.g.
// X-Authroization: Access_Token access_token="...
string accessToken = oauthRequest.AccessToken;
// Returns the Access Token for the user
/* Using the HTTP Header */
HttpWebRequest httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url);
httpWebRequest.Method = "GET";

OAuth 2 (Assertion Grant Type)
Setup
To begin, include the classes you'll be instantiating.
using Com.Pearson.Pdn.Learningstudio.OAuth;
using Com.Pearson.Pdn.Learningstudio.OAuth.Config;
using Com.Pearson.Pdn.Learningstudio.OAuth.Request;
Configuration
In OAuth 2 Assertion Grant Type, you need your Application ID, Token Key Moniker, Shared Secret, and Client String. You also need to provide the name of your application (avoid spaces).
The OAuthConfig
class is a generic carrier for the configuration information for all authentication methods. You'll add the information you need using these methods:
OAuthConfig config = new OAuthConfig();
config.ApplicationId = {applicationID};
config.ApplicationName = {applicaitonName};
config.ConsumerKey = {tokenKeyMoniker};
config.ConsumerSecret = {sharedSecret};
config.ClientString = {clientString};
The Factory
The OAuthServiceFactory
object instantiates an appropriate service for the authentication method you want to use. With this approach, you need only use the factory object and tell it which auth method you want to use, and it returns an object that will handle the access token generation. When creating the factory object, pass the config object to the constructor:
OAuthServiceFactory oauthFactory = new OAuthServiceFactory(config);
OAuth2AssertionService oauthService = oauthFactory.Build<OAuth2AssertionService>(typeof(OAuth2AssertionService));
Token Request
In this example, oauthService
is an object of the OAuth2AssertionService
class. This object will take the configuration information and the username, and requests an access token for the user. Use the token in an HTTP Header for all subsequent requests. The token lasts an hour, after which time you can repeat the same process to get a new access token.
The method you will use to request the token is GenerateOAuth2AssertionRequest
method, which has the following signature:
GenerateOAuth2PasswordRequest(string username)
Results
When you call the OAuth2AssertionService
method, it will return an object of the OAuth2Request
class. This object has several properties:
| Property | Description |
|---|---|
IDictionary<string,string> Headers |
The full HTTP header to include in your API call. They are returned as key value pairs in a IDictionary<string,string> collection. These headers are ready to use, you don't need to encode any values. Example: X-Authorization: Access_Token access_token="... |
string AccessToken |
Only the access token that was generated. |
long? ExpirationTime |
The Unix timestamp of when the token will expire. |
long? CreationTime |
Returns the Unix timestamp of when the token was generated. |
int? ExpiresInSeconds |
Returns the lifespan in seconds of the token. This is always set to 3600. |
Refresh Token
When using the Assertion grant type workflow, there is no refresh token. Simply request a new token using the same process above.
Example
using Com.Pearson.Pdn.Learningstudio.OAuth;
using Com.Pearson.Pdn.Learningstudio.OAuth.Config;
using Com.Pearson.Pdn.Learningstudio.OAuth.Request;
using System;
using System.Collections.Generic;
using System.Net;
namespace OAuth2AssertionExample
{
class Program
{
static void Main(string[] args)
{
string applicationId = ""; // Identifies your Application
string applicaitonName = ""; // No spaces for best results (e.g., MyAppName)
string tokenKeyMoniker = "";
string sharedSecret = "";
string clientString = ""; // Identifies the LearningStudio instance
string userName = ""; // provided by user through a sign-in box
Uri url = new Uri(""); // e.g., https://api.learningstudio.com/me
OAuthConfig config = new OAuthConfig();
config.ApplicationId = applicationId;
config.ApplicationName = applicaitonName;
config.ConsumerKey = tokenKeyMoniker;
config.ConsumerSecret = sharedSecret;
config.ClientString = clientString;
OAuthServiceFactory oauthFactory = new OAuthServiceFactory(config);
OAuth2AssertionService oauthService = oauthFactory.Build<OAuth2AssertionService>(typeof(OAuth2AssertionService));
// If using POST or PUT, also send the body in the third parameter:
OAuth2Request oauthRequest = oauthService.GenerateOAuth2AssertionRequest(userName);
IDictionary<string, string> oauthHeaders = oauthRequest.Headers;
// Returns HTTP Header key and value pairs
// ready to use in your API Call, e.g.
// X-Authroization: Access_Token access_token="...
string accessToken = oauthRequest.AccessToken;
// Returns the Access Token for the user
/* Using the HTTP Header */
HttpWebRequest httpWebRequest = (HttpWebRequest)HttpWebRequest.Create(url);
httpWebRequest.Method = "GET";
foreach (string oauthHeaderKey in oauthHeaders.Keys)
httpWebRequest.Headers[oauthHeaderKey] = oauthHeaders[oauthHeaderKey];
HttpWebResponse httpWebResponse = (HttpWebResponse)httpWebRequest.GetResponse();
Console.WriteLine("Status Code: {0}", (int)httpWebResponse.StatusCode);
Console.ReadLine();

Process blockages are modelled by Threshold objects that open and close according to various types of rules:
· TimeSeriesThreshold. Opens and closes when the value provided by a TimeSeries object meets various conditions.
· ExpressionThreshold. Opens and closes according to a specified expression that returns TRUE or FALSE (given by the values 1 and 0, respectively).
· SignalThreshold. Opens and closes when an entity is received by an EntitySignal object.
All types of Threshold objects share the following inputs and outputs.
Threshold Inputs
|
Keyword |
Description |
|
OpenColour |
The colour of the threshold graphic when the threshold is open. |
|
ClosedColour |
The colour of the threshold graphic when the threshold is closed. |
|
ShowWhenOpen |
A Boolean value. If TRUE, the threshold is displayed when it is open. |
|
ShowWhenClosed |
A Boolean value. If TRUE, the threshold is displayed when it is closed. |
Threshold Outputs
|
Output Name |
Description |
|
UserList |
The objects that are stopped by this Threshold. |
|
Open |
If open, then return TRUE. Otherwise, return FALSE. |
|
OpenFraction |
The fraction of total simulation time that the threshold is open. |
|
ClosedFraction |
The fraction of total simulation time that the threshold is closed. |
|
OpenCount |
The number of times the threshold's state has changed from closed to open. |
|
ClosedCount |
The number of times the threshold's state has changed from open to closed. |
The response of an object to the closure of one of its Thresholds depends on which one of the following keywords was used.
Keywords that accept Thresholds
|
Keyword |
Description |
|
ImmediateThresholdList |
A list of thresholds that must be satisfied for the object to operate. Operation is stopped immediately when one of the thresholds closes. If a threshold closes part way though processing an entity, the work is considered to be partly done and the remainder is completed once the threshold re-opens. |
|
ImmediateReleaseThresholdList |
A list of thresholds that must be satisfied for the object to operate. Operation is stopped immediately when one of the thresholds closes. If a threshold closes part way though processing an entity, the work is interrupted and the entity is released. |
|
OperatingThresholdList |
A list of thresholds that must be satisfied for the object to operate. If a threshold closes part way though processing an entity, the remaining work is completed and the entity is released before the object is closed. |
|
ReleaseThresholdList |
A list of thresholds that must be satisfied for the object to operate. If a threshold closes part way though processing an entity, the remaining work is completed, but the entity is retained until the threshold re-opens. |
A given Threshold can appear in only one of these keywords at a time. A single Threshold can be used by multiple objects.

Susan Granger's review of "THE THIN RED LINE" (20th Century-Fox)
Writer/director Terrence Malick, known as the J.D. Salinger of the movies, is the near-mythic Harvard graduate, Rhodes Scholar, former journalist and philosophy professor who has exiled himself from Hollywood's film industry for nearly two decades after making "Badlands" and "Days of Heaven." Now he's back with this screen adaptation of James Jones' novel about the men in an Army Rifle company, C-for-Charlie, who suffer and change, making psychological discoveries about themselves, as they attempt to capture a Japanese base on an island in the South Pacific during the W.W.II battle of Guadalcanal. The casts consists of Sean Penn (a cynical sergeant), Nick Nolte (an ambitious officer), Elias Koteas (their conscience-stricken leader), Woody Harrelson (a doomed sergeant), John Cusack (a self-sacrificing captain), John Travolta (with a mustache) George Clooney (in a cameo), with Ben Chaplin and newcomer Jim Caviezel as the two pivotal privates. Filmed in Port Douglas, a coastal community near Australia's Great Barrier Reef, the cinematography is filled with sweeping imagery and the story is punctuated with fierce bursts of energy and as Malick explores how the various men confront fear. While his sense of irony and humanity is evident, Malick's abstract, emotionally detached style just doesn't seem to mesh with the structured urgency of a combat tale. The pace is ponderous, filled with contemplative, philosophical musings about God and nature and the insanity of war. Malick's metaphors are often opaque in meaning and pretentious, if not condescending, as dialogue, like "The closer you are to Caesar, the greater the fear." On the Granger Movie Gauge of 1 to 10, "The Thin Red Line" is a meditative 7, a bizarre war movie.

Slower response since version 2 was deployed. Worse in vip portals.
Investigate more services.
Confirm slow traces.
It seems version 2 introduced ChaosMonkey delays in several workloads.
Apply on travels, hotels, insurances, cars and flight services
Web portal traffic is back to normal response time
Evenly Splitted traffic between fast and slow versions
Reduce traffic routed to version 1
Slower version only gets a 10% of the traffic

@Kenny Lau Voila, some homework for you :grinning:
Close enough to dark magic for my tastes. The token for ←

. But the case I compared it with goes the other way around: (|
is an alias for ⟨
. So you can parse angle brackets just fine, but for left arrows, you'd better use ascii.
I think this line is redundant, then, which was a red herring. https://github.com/leanprover/lean/blob/master/library/init/meta/interactive.lean#L351

I started Web Development as a hobby in 2018 then and party time, I was working on a free Udemy online platform thats when I discovered my passion and become serious about it. I would be greatful to be given an oppotunity and work as a Junior Web developer. Im very hardworking and willing to learn constantly.
Bellow are the projects which I've created during my time i was learning. However they are not 100% complete I'm working on them to make them funtional as the proof of my knowledge I have gained so far.
View ResumeA movie app that created using stripe API the you can search for movies it will filter and return a collection of movies.
Robot Friends App is the first application that I've created. The application simplpy fetch the data from json placeholder backend and displays it in little cards. It also uses search bar to filter the robots to display them according to the letters in you type on the search bar. I have another similar project that uses redux library as state management.
The Brain Detector is the aplication that used to detect human faces on the picture. Simply copy and paste the image url and click detect
Crown Clothing is a online shopping for that can process online payments the project is not yet done im working on it to make it great.

branches, for brief loops, and other such purposes. To define
an anonymous label, use an asterisk. To refer to an anonymous
label, use a series of +
or - signs. + refers to
the next anonymous label, ++ the label
after that, etc. Likewise, - is the most
recently defined label, -- the one before
that, and so on. The main body of the Hello World program
with anonymous labels would be:
ldx #0
* lda hello, x
beq +
jsr $ffd2
inx
bne -
* rts |
It is worth noting that anonymous labels are globally available.
They are not temporary labels, and they ignore scoping
restrictions.

Hajj fare remains unchanged for 2020 - Council
The Hajj Pilgrimage fare will remain unchanged for the 2020 Hajj pilgrimage after the government absorbed an $80 increase to the 2019 fare of GH¢19,500, an equivalent of $3,500 dollars.
The Pilgrimage Affairs Office of Ghana (PAOG), in collaboration with Hajj Agents Association, has announced that an additional $80 fee has been imposed by the Saudi Arabian government for the 2020 Hajj but the government has absorbed that increase.
The unsubsidized Hajj Pilgrimage fare is GH¢24,000 but the Ghanaian government pays a GH¢4,500 subsidy for all pilgrims.
The new fare was announced by the Chairman of the PAOG, Sheikh I.C. Quaye, at a 2019 Hajj Thanksgiving Service held today at the Hajj Village in Accra

HawtDispatch is an abstract model for expressing concurrency via simple but powerful API.
At the core, HawtDispatch provides serial FIFO queues to which runnables may be submitted. Runnables submitted to these dispatch queues are invoked on a pool of threads fully managed by the system. No guarantee is made regarding which thread a runnable will be invoked on; however, it is guaranteed that only one runnable submitted to the FIFO dispatch queue will be invoked at a time.
HawtDispatch also provides dispatch sources to handle converting events like NIO Socket readiness events into callbacks to runnables executed on the dispatch queues.

I am working with Pharo for 7 years now. And all my project starts the same way: create a test, create a class, create a Baseline, and commit and push. Even if most of these tasks are easy for everyone. Dealing with baseline seems to be the hardest for people. Probably because we do not do it in our day-to-day development.
I have created a simple, and efficient, way to deal with baseline. This solution does not enable all the features baselines can offer, but it allows one to create a simple baseline, make its project available for everyone, and not require one to dig into documentation all the time.
So, let’s have a look at how to create a baseline in 5min.
Create a baseline in 5min
First, create a package with as name: BaselineOf
+ the name of your project (better, the name of the git repository).
Considering a project named “Cointreau”, I create a package BaselineOfCointreau
.
Then, inside this package, I create a class with the same name.
The class must be a subclass of BaselineOf
It is not mandatory to have the same name, but again, here I present a simple solution.
BaselineOf << #BaselineOfCointreau
slots: {};
package: 'BaselineOfCointreau'
In the Baseline class, we will create 4 methods: baseline:
, definePackages: spec
, defineDependencies: spec
, defineGroups: spec
.
The first method is always the same, so you can copy-paste it.
baseline: spec
<baseline>
spec
for: #common
do: [
self defineDependencies: spec.
self definePackages: spec.
self defineGroups: spec ]
The second method is the one in which you declare the packages of your project and their dependencies. These packages are the ones you push to your git repository.
In our example, there are three packages: Cointreau
, Cointreau-Tests
, and Cointreau-Bottle
.
The Cointreau-Tests
package requires the Cointreau
package to be loaded first.
The Cointreau-Bottle
package requires something named BottleFactory
.
We will declare it in the defineDependencies:
method.
definePackages: spec
spec
package: 'Cointreau';
package: 'Cointreau-Tests' with: [ spec requires: #( 'Cointreau' ) ];
package: 'Cointreau-Bottle' with: [ spec requires: #( 'BottleFactory' ) ]
The defineDependencies:
method allows one to declare dependencies to other baselines.
In our example, the Cointreau-Bottle
package needs that the project BottleFactory
to be loaded.
The project is hosted in GitHub, under the user badetitou.
The project has several branches, and we decided to select branch v2
.
The Pharo code is under the directory src
.
defineDependencies: spec
spec
baseline: 'BottleFactory'
with: [ spec
repository: 'github://badetitou/BottleFactory:v2/src' ].
The final method is defineGroups: spec
.
Groups are already an advanced feature if it is your first baseline.
It allows one to load only part of a project.
By default, a group named default
exists and loads all packages.
For our example, we will create a group named core
that will not load Cointreau-Bottle
.
You can also let the method empty if you do not want to create group at first. However, I believe already having this method is good to have a complete setup.
defineGroups: spec
spec group: 'core'
with: #( 'Cointreau' 'Cointreau-Tests' )
Congrats! You have created your first baseline.
Load the baseline
Once you have created a baseline, you might want to use it to load your project in Pharo. Based on this template, you can load any of your projects if the same Pharo code.
The GitHub user is the name of the organization or GitHub user.
The project is the name of the project in GitHub.
The commitish is the branch or the tag/release you want to load.
The path is the location in the repository that contains your Pharo code.
Finally, the baseline is the name of your Baseline (without the prefix BaselineOf
).
Metacello new
githubUser: 'badetitou' project: 'Cointreau' commitish: 'main' path: 'src';
baseline: 'Cointreau';

Back our tax man
Rangers news: SNP MSP John Mason lodges motion for public trust in HMRC after tax row
by Gary TaylorGLASGOW MSP John Mason has lodged a motion in parliament urging for public trust in HMRC over the Rangers tax row.
The SNP politician addressed the recent story reported by The Times claiming that the tax authorities were set to wipe out as much as £50million from a tax bill owed by Rangers' old operating company after a "multimillion-pound blunder".
Former Ibrox chairman John McClelland has said the club wouldn't have plunged into liquidation in 2012 if the lower bill reported had been the figure claimed before Craig Whyte bought the club for £1.
HMRC chief Jim Harra personally sent a letter to the editor of The Times Scotland over "inaccurate and partial reporting" of the tax issues.
But the tax authority is adamant it has not made any mistakes in how they calculated Gers' tax liabilities
And now Mr Mason has said that trust in the tax system is "paramount".
His motion read: "That the Parliament notes the recent publication by The Times, which stated that Rangers FC’s insolvency was the result of an HMRC overestimation of taxes owed by £50 million; understands that HMRC has stated that no such mistakes were made and that it won its case against Rangers’ tax avoidance scheme in the Supreme Court; recognises that HMRC has also stated that "inaccurate and partial reporting only serves to undermine public trust in the tax system", and considers that public trust in the tax system is paramount given the importance of taxation for the provision of public services and ensuring a fairer and more progressive Scotland."
Rangers then broke their silence over the affair to admit to "concerns" at suggestions HMRC got their sums wrong.
An Ibrox spokesperson said: "The Times story, if it is shown to be accurate, throws up a great many questions and is a cause for concern.
"Rangers will take time to consider any courses of action which may become feasible."
Earlier this year Mr Mason sparked outrage by comparing the Celtic Boys Club sex abuse scandal to Rangers avoiding tax.
The politician suggested there were “parallels” between beasts preying on children and the Ibrox side keeping cash from public coffers.
He wrote in an email to a voter: “In both cases young people are suffering. In the one children are suffering directly at the hands of child abusers.
“In the other very rich people are not paying the tax due which means schools and hospitals get less money than they need.
"I do accept they are different types of crimes, but they are both crimes with real victims, usually the most vulnerable in our society.”
