Effective date: 20 October 2017
We take your privacy seriously. This Privacy Policy explains what personal information we collect and how we use it.
We encourage you to read this policy thoroughly. To make it easier, we’ve broken it up into bite-size chunks and longer sections have a heading and summary. If you want to know more about these sections, just click on the ‘Learn more’ link at the end of each summary.
When we refer to ‘Experian’ in this Privacy Policy, we mean Experian Limited.
Experian is part of a group of companies whose parent company is listed on the London Stock Exchange (EXPN) as Experian plc. The Experian group of companies has its corporate HQ in Dublin, Ireland, and its operational HQs in Costa Mesa, California and Nottingham, UK.

We will also collect other information about you and the devices you use to access our website, or we may ask third parties to do this for us, in these cases we do so by using technologies such as cookies. See also our Cookies policy.
When you apply for Experian services we will ask you to provide some contact information. Contact information may include some or all of the following: full name, previous names, residential address, previous residential addresses, date of birth, landline phone number, mobile phone number and email address.
Where the services you select carry a cost, we will ask you to provide some payment information. Payment information may include some or all of the following: credit card and debit card details.

For the web monitoring services that are available to some customers, we will ask you to provide your chosen information to be monitored. This may include some or all of the following: passport number, driving licence number, national insurance number, credit card details and any other information you choose to have us monitor.

We may need to access data we already hold about you on our credit bureau, or we may gather similar information from other credit reference agencies (Callcredit and Equifax). This may include (but is not limited to) some or all of the following: details of credit accounts held and repayment performance as well as public information such as inclusion on the electoral roll, bankruptcies and county court judgements.
We use your personal information in lots of ways to make our products and services as effective as possible.
We will use your information to accept you as a new/returning customer and continue to provide you with our products and services.
We will let you know by email, SMS, push notification or when you log in to the site if there are significant changes to our products, their features, our terms, or our privacy policy.
As part of providing services to you we will confirm your identity and authenticate the information you provide for security purposes.
Establishing your identity is important as the services may provide you with your personal credit information (such as your credit score or credit report) and we must be sure you are who you say you are. Identity checking may also involve checking the registration information you give us against information we already hold about you as a credit reference agency and potentially publicly available information about you such as from social media.
If we are unable to confirm your identity from the registration information you provide, we will let you know by using the contact details you have provided and you may then have the option to make a written application and provide further proof of your identity.
We will use your information to process the payments you commit to when signing up to our services and for the collection of any future payments or overdue amounts for those services.
Your payment card provider may let us know if the card details relating to your Experian payment change. If this happens, we reserve the right to update certain card details to make sure your access to our services isn’t interrupted.
So for example, if you get a new payment card with a later expiry date to the one you currently pay with (but all the other details stay the same), we may update your payment card expiry date accordingly.
We will use your information to be able to provide and improve the customer support we provide to you (e.g. when you have questions or when you forget your log-in information).
We will use your information to send you alerts where ‘Alerts’ are part of the service you ask us to provide e.g.
We will use your information to contact you to tell you about changes to or issues affecting the services you are taking.
When you use our comparison service to search for products, the information you provide is used to retrieve information about products relevant to your search and create a table which allows you to compare them.
Where eligibility ratings are available, information from your credit file with Experian (and sometimes Callcredit and Equifax) is also used to help you understand whether you are likely to be accepted.
In some circumstances, we will share that information and your personal information (such as name and address) with brokers, lenders and providers of credit and financial products themselves (as described in the section "Who we share your personal information with").
When you search for products, we may contact you by email or SMS to confirm activity relating to use of our comparison services, such as details of the searches you have made, results that you have seen when searching, or information about introductions you’ve requested to brokers and lenders.
As part of our free services (which are available to all customers), Experian will retrieve and use your credit bureau data (whether it’s from Experian or the other two main credit reference agencies Equifax and Callcredit) to check your eligibility (as described in the above section ‘To provide comparison services and create eligibility ratings’) for third party products or services and notify you of credit opportunities, products and services that you may be eligible for.
When you log in to the website, we will show you updated eligibility ratings for products and services that may be available to you.
As part of this service we may also notify you by e-mail, SMS or post of new or updated eligibility ratings for products and services; for example if new products and services are added, or your eligibility has changed. You can chose not to receive email, SMS and postal communications about product eligibility whenever you want from your Experian Account page.
We will check your eligibility for third party products and services, and may send you alerts:
We will use your information for marketing purposes such as if we think one of our products, services or offers, or those of our third party partners, may interest you, we or they may contact you about them by email, SMS, on the phone, through app notifications or through the post.
If your Experian subscription has finished, we may contact you and invite you to re-subscribe to the same or a different service or product, or to use certain free features on our website.
You can opt out of marketing communications at any time by following the instructions in the email or SMS or by contacting us at<EMAIL_ADDRESS>You can turn off app notifications at any time using the tools provided in your mobile operating system.
Experian may select particular customers and invite them to be involved in market research. If you accept this invitation, we will use the feedback you give us to improve our products and services.
From time to time we will run prize draws, competitions, promotions and surveys and, we will use the personal data you provide to us, to run such activities and to do what we agree to do as part of them.
We may use your information for fraud investigation, detection and prevention measures and in order to provide suitable security for your account and your information that we hold (such as to enable us to prevent others logging in to your account without your permission from unknown devices).
We may use your information for the investigation, detection and prevention of crime (other than fraud).
We will use your information to ensure that our team has the knowledge and expertise they need to ensure we provide the best possible experience to our customers when interacting with us.
We will use your information for reporting and analytical purposes (e.g. how many of our customers are in the north or south of the country) to enable us to improve our products and services and to provide appropriate levels of support to our customers.
We will use your information to track your activity on our apps and on our websites to help us better understand your interests and how you interact with us. We may also use this information to help us detect if someone else is trying to access your account or use the services you take from us. We will also use this information to better engage with you and to ensure that you get the best service we can provide and improve our products in the future.
Like any business, we need to ensure that we maintain comprehensive and up to date records of the ways we process your personal information and other operational activities and therefore we will process the information you provide for record-keeping, updates and general administrative purposes.
Whilst we will try to make sure that you are happy with the service we provide and do not feel the need to complain, if you do complain to us, we will use the information we have about you to help us manage your complaint.
Like any other business, we are required to comply with many laws and regulations. We will, where necessary, use your personal data to the extent required to enable us to comply with these requirements.
Personal information you provide to us may be used to improve the credit bureau information we already hold about you in our role as a credit reference agency. E.g. if you provide a different address to the one we hold already we may store the new address in the credit bureau information to aid quicker identification of you and ensure that lenders can see a full picture of you when making lending decisions, it also aids identification and verification in the credit application process.
Experian may use performance tracking technology within our emails to improve our future interactions with you. This means we are able to capture information including (but not limited to) the time and date you open our e-mails and the type of device used to open the email.
We use this information primarily to understand whether our e-mails are opened and what links are clicked on by our customers. We then use this information to improve the emails that we send to you and the services that we provide.
We may share this information with other organisations to help them improve their own interactions with you. Your personal data will not be passed to any third party for marketing purposes unless you already have an existing relationship with them. You will not receive marketing emails from such third party organisations unless you have given your prior consent to them to send emails to you.
Further information is included in our Cookies Policy.
If we use your personal information for any purposes that are not set out in this Privacy Policy we promise to let you know exactly what we will use it for before we go ahead and use it and obtain your consent where appropriate.
Data protection laws require that, where were process your personal data, we must satisfy at least one prescribed condition for processing. These are set out in data protection law and we rely on a number of different conditions for the activities we carry out.
In most cases, the information described above will be provided to us by you because you want to take services from us or engage with us and our use of your information will be governed by contract terms. Giving this information to us is therefore your choice. If you choose not to give all or some of it to us, this may affect our ability to provide the services you want, to you.

You will be asked to consent to this before using our website. If you choose not to give your consent, or you later remove your consent, this may affect our ability to provide the services you want, to you. We may also rely on consent in the following scenarios:-
In the United Kingdom, we can also use personal information where the benefits of doing it are not outweighed by the interests or fundamental rights or freedoms of individuals. The law calls this the “Legitimate Interests” condition for processing. Where we rely on it, the benefits being pursued by us are:-
We share your personal information only with those persons who need to handle it so we can provide the Experian products and services you’ve signed up to. We also share it with companies within the Experian group who manage some parts of the services for us; with suppliers who provide services to us which require access to your personal information only; and with resellers, distributors and agents involved in delivering the services we provide where necessary for them to do so.
Lastly, we may also provide your personal information to fraud prevention agencies. This is to protect the Experian group of companies and our customers, to keep our systems secure, or where it’s necessary to protect either yours or our best interests.
As a member of the Experian group of companies, we can benefit from the large IT infrastructure and expertise that exists within our business. This means that the personal data you provide to us may be accessed by members of our group of companies for support and administrative purposes.

The police, other law enforcement agencies, regulators, as well as public bodies such as local and central authorities can sometimes request personal information. This may be for the purposes of preventing or detecting crime, apprehending or prosecuting offenders, assessing or collecting tax, investigating complaints or assessing how well a particular industry sector is working.
In some circumstances, we will share credit report information and your personal information (such as name and address) with brokers, lenders and providers of credit and financial products themselves for purposes that may include:
You can obtain a copy of the information we hold about you. See section Your rights to how we use your personal information for further information on how you can do this.
Experian is based in the UK, which is where our main databases are. We also operate elsewhere in and outside the European Economic Area, so we may access your personal information from and transfer it to these locations as well. Don’t worry though, any personal information we access from or transfer to these locations is protected by European data protection standards.
While countries in the European Economic Area all ensure rigorous data protection laws, there are parts of the world that may not be quite so rigorous and don’t provide the same quality of legal protection when it comes to your personal information.
To make sure we keep your personal information safe, we apply strict safeguards when transferring it overseas. For example:
It is important that you understand your rights in relation to your personal information and how you can contact us if you have questions or concerns.
If you’ve given us consent to process your personal information, you have the right to withdraw that consent at any time by contacting us on<EMAIL_ADDRESS>You can also make changes to that preference in your Experian account.
You can also ask for access to the personal information we hold about you and request that we correct any mistakes, restrict or stop processing or delete it. It’s worth noting that in some cases if you do ask us to correct, delete or stop processing it, we won’t always be required to do so. If that is the case, we will explain why. The statutory fee is £10.00, except in the case of obtaining a copy of your credit report, for which the statutory fee is £2.00.
In certain circumstances (e.g. where you provide your information to us (a) with consent to process it or (b) where the processing is necessary for the performance of our contract with you) you can require that we provide the information we hold about you either to you or a third party in a commonly used format. This only applies if we are processing it using automation only. If you would like more information about this, let us know by contacting us at<EMAIL_ADDRESS>We will try to ensure that we deliver the best levels of customer service but if you think we are falling short of that commitment, please let us know by contacting us at<EMAIL_ADDRESS>If you're still unhappy with any aspect of how we handle your personal information you also have the right to contact the Information Commissioner’s Office (ICO), the supervisory authority that regulates handling of personal information in the UK. You can contact them by:
You may also see our full complaints handling procedure and how to make a complaint. If we cannot resolve things under that procedure, then you may have the right to refer your complaint, free of charge, to the Financial Ombudsman Service. The contact details for the Financial Ombudsman Service are: Telephone: 0300 123 9 123, or from outside the UK +44 20 7964 1000 E<EMAIL_ADDRESS>W: www.financial-ombudsman.org.uk Financial Ombudsman Service Exchange Tower London E14 9SR
You also have the option to register your complaint using the European Commission Online Dispute Resolution (ODR) platform. This is a web-based platform that is designed to help consumers who have bought goods or services online to deal with issues arising from their purchase.
Online privacy and security is the most important aspect of any customer service and we take it extremely seriously. We use a variety of the latest technologies and procedures to protect your personal information from unauthorised access, destruction, use or disclosure.
We restrict access to your personal data to those employees, and third parties, who need to know that information to provide products or services to you. We maintain physical, electronic, and procedural safeguards to protect your personal data.
Experian protects your information over the Internet by using secure web server technologies, which allows web browser programs (such as Microsoft Internet Explorer) to interact with Experian's web server via an encrypted session. Experian employs a Secure Sockets Layer (SSL) connection that provides an encrypted connection between your computer and Experian. The 128 bit encrypted connection scrambles ordinary text or data into cypher text to safeguard sensitive information during its journey across the Internet. The information is decrypted, or put back into a readable format, when it reaches its intended destination. When you visit any Experian website you may move in and out of secured areas. Any time that you are on a registration page or viewing your personal credit report, you will be in a secured area.
We’ll keep your personal information for as long as we need it to provide the Experian products and services you’ve signed up to. We may also keep it to comply with our legal obligations, resolve any disputes and enforce our rights. These reasons can vary from one piece of information to the next and depend on the products or services you’re signed up to, so the amount of time we keep your personal information for may vary.
In all cases, our need to use your personal information will be reassessed on a regular basis, and information which is no longer required for any purposes will be disposed of.
We can update this Privacy Policy at any time and ideally you should check it regularly for updates. We won’t alert you to every little change, but if there are any really important changes to the Policy or how we use your information we’ll let you know and where appropriate ask for your consent.

prefmod: Utilities to Fit Paired Comparison Models for Preferences
Generates design matrix for analysing real paired comparisons and derived paired comparison data (Likert type items/ratings or rankings) using a loglinear approach. Fits loglinear Bradley-Terry model (LLBT) exploiting an eliminate feature. Computes pattern models for paired comparisons, rankings, and ratings. Some treatment of missing values (MCAR and MNAR). Fits latent class (mixture) models for paired comparison, rating and ranking patterns using a non-parametric ML approach.

Product QML Type
A product for in-app purchasing. More...
| Import Statement: | import QtPurchasing 1.0 |
| Since: | QtPurchasing 1.0 |
Properties
- description : string
- identifier : string
- price : string
- status : enumeration
- store : object
- title : string
- type : string
Signals
- onPurchaseFailed(object transaction)
- onPurchaseRestored(object transaction)
- onPurchaseSucceeded(object transaction)
Methods
- purchase()
- resetStatus()
Detailed Description
Product contains information about a product in the external market place. Once the product's identifier and type are set, the product will be queried from the external market place. Properties such as price will then be set, and it will be possible to purchase the product. The status property holds information on the registration process.
Note: It is not possible to change the identifier and type once they have both been set and the product has been registered.
Property Documentation
This property holds the description of the product once it has been successfully queried from the external market place. The title is localized if the external market place has defined a description in the current users locale.
This property holds the identifier of the product in the external market place. It must match the identifier used to register the product externally before-hand.
When both the identifier and type is set, the product is queried from the external market place, and its other properties are updated asynchronously. At this point, the identifier and type can no longer be changed.
The following example queries an unlockable product named "myUnlockableProduct" from the external market place.
Store { Product { identifier: "myUnlockableProduct" type: Product.Unlockable // ... } }
This property holds the price of the product once it has been successfully queried from the external market place. The price is a string consisting of both currency and value, and is usually localized to the current user.
For example, the following example displays the price of the unlockable product named "myUnlockableProduct":
Store { Product { id: myUnlockableProduct identifier: "myUnlockableProduct" type: Product.Unlockable // ... } } Text { text: myUnlockableProduct.status === Product.Registered ? "Price is " + myUnlockableProduct.price : "Price unknown at the moment" }
When run in a Norwegian locale, this code could for instance display "Price is kr 6,00" for a one-dollar product.
This property holds the current status of the product in the registration sequence.
- Product.Uninitialized - This is initial status, before the identifier property has been set.
- Product.PendingRegistration - Indicates that the product is currently being queried from the external market place. The product gets this status when its identifier is set.
- Product.Registered - Indicates that the product was successfully found in the external market place. Its price can now be queried and the product can be purchased.
- Product.Unknown - The product could not be found in the external market place. This could for example be due to misspelling the product identifier.
Store { Product { identifier: "myConsumableProduct" type: Product.Consumable onStatusChanged: { switch (status) { case Product.PendingRegistration: console.debug("Registering " + identifier); break case Product.Registered: console.debug(identifier + " registered with price " + price); break case Product.Unknown: console.debug(identifier + " was not found in the market place"); break } } // ... } }
This property holds the store containing the product. When the product is created as a child of the store, this is set automatically to the parent, as in the following example:
Store { Product { // No need to set the store explicitly here, as it will automatically be // bound to the parent identifier: "myConsumableProduct" type: Product.Consumable } Product { // No need to set the store explicitly here, as it will automatically be // bound to the parent identifier: "myUnlockableProduct" type: Product.Unlockable } }
However, in some advanced use cases, for example when products are created based on a model, it's also possible to create the product anywhere in the QML document and set the store explicitly, like in the following example:
ListModel { id: productModel ListElement { productIdentifier: "myConsumableProduct" productType: Product.Consumable } ListElement { productIdentifier: "myUnlockableProduct" productType: Product.Unlockable } } Store { id: myStore } Instantiator { model: productModel delegate: Product { identifier: productIdentifier type: productType store: myStore } }
This property holds the title of the product once it has been successfully queried from the external market place. The title is localized if the external market place has defined a title in the current users locale.
This property holds the type of the product in the external market place.
It can hold one of the following values:
- Product.Consumable The product is consumable and can be purchased more than once by the same user, granted that the transaction for the previous purchase has been finalized.
- Product.Unlockable The product can only be purchased once per user. If the application is uninstalled and reinstalled on the device (or installed on a new device by the same user), purchases of unlockable products can be restored using the store's restorePurchases() method.
When both the identifier and type is set, the product is queried from the external market place, and its other properties are updated asynchronously. At this point, the identifier and type can no longer be changed.
The following example queries an unlockable product named "myUnlockableProduct" from the external market place.
Store { Product { identifier: "myUnlockableProduct" type: Product.Unlockable // ... } }
Signal Documentation
This handler is called when a purchase was requested for a given product, but the purchase failed. This will typically happen if the application calls purchase() on a product, and the user subsequently cancels the purchase. It could also happen under other circumstances, for example if there is no suitable network connection.
All products should have an onPurchaseFailed
handler.
After a proper reaction is taken, the finalize() function should be called on the transaction object. If this is not done, the handler may be called again the next time the product is registered.
The following example reacts to a failed purchase attempt by calling a custom function to display a message to the user.
Store { Product { id: myConsumableProduct identifier: "myConsumableProduct" type: Product.Consumable onPurchaseFailed: { myDisplayHelper.message("Product was not purchased. You have not been charged.") transaction.finalize() } // ... } }
This handler is called when a previously purchased unlockable product is restored. This can happen when the restorePurchases() function in the current Store is called. The onPurchaseRestored
handler will then be called for each unlockable product which has previously been purchased by the user.
Applications which uses the restorePurchases() function should include this handler in all unlockable products. In the handler, the application should make sure information about the purchase is stored and call finalize() on the transaction object if the information has been successfully stored (or has been verified to already be stored).
The following example calls a custom function which either saves the information about the purchase or verifies that it is already saved. When the data has been verified, it finalizes the transaction. If it could not be verified, it calls another custom function to display an error message to the user. If the transaction is not finalized, the handler will be called again for the same transaction the next time the product is registered (on application start-up).
Store { Product { id: myUnlockableProduct identifier: "myUnlockableProduct" type: Product.Unlockable onPurchaseRestored: { if (myStorage.savePurchaseInformation(identifier)) { transaction.finalize() } else { myDisplayHelper.message("Failed to store purchase information. Is there available storage?") } } // ... } }
This handler is called when a product has been purchased successfully. It is triggered when the application has called purchase() on the product and the user has subsequently confirmed the purchase, for example by entering their password.
All products should have a handler for onPurchaseSucceeded. This handler should in turn save information about the purchased product and when the information has been stored and verified, it should call finalize() on the transaction object.
The handler should support being called multiple times for the same purchase. For example, the application execution might by accident be interrupted after saving the purchase information, but before finalizing the transaction. In this case, the handler should verify that the information is already stored in the persistent storage and then finalize the transaction.
The following example attempts to store the purchase state of a consumable product using a custom made function. It only finalizes the transaction if saving the data was successful. Otherwise, it calls another custom function to display an error message to the user.
Store { Product { id: myConsumableProduct identifier: "myConsumableProduct" type: Product.Consumable onPurchaseSucceeded: { if (myStorage.savePurchaseInformation(identifier)) { transaction.finalize() } else { myDisplayHelper.message("Failed to store purchase information. Is there available storage?") } } // ... } }
If the transaction is not finalized, the onPurchaseSucceeded handler will be called again the next time the product is registered (on application startup.) This means that if saving the information failed, the user will have the opportunity of rectifying the problem (for example by deleting something else to make space for the data) and the transaction will be completed once they restart the application and the problem has been solved.
Note: A purchased, consumable product can not be purchased again until its previous transaction is finalized.
Method Documentation
Launches the purchasing process for this product. The purchasing process is asynchronous. When it completes, either the onPurchaseSucceeded or the onPurchaseFailed handler in the object will be called with the resulting transaction.
Resets the status of this product and retries querying it from the external market place.
This method can be used when querying the product failed for some reason (such as network timeouts).
This QML method was introduced in QtPurchasing 1.0.2.

| 006:091 Khan | : |
They (the Jews, Quraish pagans, idolaters, etc.) did not estimate Allah with an estimation due to Him when they said: "Nothing did Allah send down to any human being (by inspiration)." Say (O Muhammad SAW): "Who then sent down the Book which Musa (Moses) brought, a light and a guidance to mankind which you (the Jews) have made into (separate) papersheets, disclosing (some of it) and concealing (much). And you (believers in Allah and His Messenger Muhammad SAW), were taught (through the Qur'an) that which neither you nor your fathers knew." Say: "Allah (sent it down)." Then leave them to play in their vain discussions. |
| 006:091 Maulana | : |
And they honour not Allah with the honour due to Him, when they say: Allah has not revealed anything to a mortal. Say: Who revealed the Book which Moses brought, a light and a guidance to men -- you make it into (scattered) papers, which you show and you conceal much? And you are taught that which neither you nor your fathers new. Say: Allah. Then leave them sporting in their idle talk. |
| 006:091 Pickthal | : |
And they measure not the power of Allah its true measure when they say: Allah hath naught revealed unto a human being. Say (unto the Jews who speak thus): Who revealed the Book which Moses brought, a light and guidance for mankind, which ye have put on parchments which ye show, but ye hide much (thereof), and (by which) ye were taught that which ye knew not yourselves nor (did) your fathers (know it)? Say: Allah. Then leave them to their play of cavilling. |
| 006:091 Rashad | : |
They never valued GOD as He should be valued. Thus, they said, "GOD does not reveal anything to any human being." Say, "Who then revealed the scripture that Moses brought, with light and guidance for the people?" You put it down on paper to proclaim it, while concealing a lot of it. You were taught what you never knew - you and your parents. Say, "GOD (is the One who revealed it)," then leave them in their heedlessness, playing. |
| 006:091 Sarwar | : |
They have no true respect of God when they say, "God has not sent anything to a mortal being." (Muhammad), tell them, "Who revealed the Book containing a light and guidance for the people which Moses brought? You wrote down only some parts of the original on paper and hid much, even after having learnt from it, that which neither you nor your fathers knew." Tell them, "God has (revealed the Quran)," and then leave them alone to pursue their useless investigations. |
| 006:091 Shakir | : |
And they do not assign to Allah the attributes due to Him when they say: Allah has not revealed anything to a mortal.  And you were taught what you did not know, (neither) you nor your fathers. Say: Allah then leave them sporting in their vain discourses. |
| 006:091 Sherali | : |
And they do not make a just estimate of the attributes of ALLAH, when they say, 'ALLAH has not revealed anything to any man. Say, 'Who revealed the Book which Moses brought, a light and a guidance for the people - though you treat it as scrapes of paper, some of which you show while you hide much thereof and you have been taught that which neither you nor your fathers knew?' Say, 'ALLAH.' Then leave them to amuse themselves with idle talk. |

It is possible to setup client/server requests over SSL. EJB requests from a remote client can happen two different ways:
Note, TomEE can be setup to support ejbds.
First, you'll need to setup Tomcat (TomEE) with SSL as described here:
http://tomcat.apache.org/tomcat-7.0-doc/ssl-howto.html
Once that is done and the tomee
webapp can be accessed with https
, an EJB client can invoke over https
using the following
InitialContext
setup:
Properties p = new Properties();
p.put("java.naming.factory.initial", "org.apache.openejb.client.RemoteInitialContextFactory");
p.put("java.naming.provider.url", "https://<IP_ADDRESS>:8443/tomee/ejb");
// user and pass optional
p.put("java.naming.security.principal", "myuser");
p.put("java.naming.security.credentials", "mypass");
InitialContext ctx = new InitialContext(p);
MyBean myBean = (MyBean) ctx.lookup("MyBeanRemote");
If you setup Tomcat (TomEE) to use the APR (Apache Portable Runitme) implementation of SSL on the server side, and you have connection issues like connection reset, you'll have to set 'https.protocols' system property. 'https.protocols' property must be set according to the SSLProtocol parameter of the HTTPS connector configuration :
http://tomcat.apache.org/tomcat-7.0-doc/config/http.html
You can also have a look a this :
http://docs.oracle.com/javase/1.4.2/docs/guide/plugin/developer_guide/faq/troubleshooting.html
The SSL version of the ejbd
protocol is called ejbds
and is enabled and setup in OpenEJB Standalone by default.
Its configuration conf/ejbds.properties
looks like this:
server = org.apache.openejb.server.ejbd.EjbServer
bind = <IP_ADDRESS>
port = 4203
disabled = false
threads = 200
backlog = 200
secure = true
discovery = ejb:ejbds://{bind}:{port}
To access this service from a remote client, the InitialContext
would be setup like the following:
Properties p = new Properties();
p.put("java.naming.factory.initial", "org.apache.openejb.client.RemoteInitialContextFactory");
p.put("java.naming.provider.url", "ejbd://localhost:4201");
// user and pass optional
p.put("java.naming.security.principal", "myuser");
p.put("java.naming.security.credentials", "mypass");
InitialContext ctx = new InitialContext(p);
MyBean myBean = (MyBean) ctx.lookup("MyBeanRemote");
This is a pending feature By default, the ejbds protocol connects with SSL_DH_anon_WITH_RC4_128_MD5. That means your connection is encrypted and the integrity of the transmission is verified. However, this only protects your from eavesdroppers, it offers absolutely zero protection from Man in the Middle attacks. This sort of attack could be pulled off without your knowledge and the attacker has the ability to intercept, monitor, and even modify your messages. If the attacker could control a router on your connection path, this attack could be trivially pulled off with nothing more but the OpenEJB server and client.
To secure your connections against this sort of attack, your client can cryptographically prove it's talking to the correct server before sending any data. To do this, simply select one or more secure cipher suites that your J2SE provider supports from this listing.
You must now instruct the client and server to use that suite.
On the server:
server = org.apache.openejb.server.ejbd.EjbServer
bind = <IP_ADDRESS>
port = 4203
disabled = false
threads = 200
backlog = 200
secure = true
enabledCipherSuites = TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA
discovery = ejb:ejbds://{bind}:{port}
On the client, you must supply a property:
-Dopenejb.client.enabledCipherSuites=TLS_RSA_WITH_AES_256_CBC_SHA,TLS_RSA_WITH_AES_128_CBC_SHA
The final piece is to make sure your server has available a private certificate that the the client can trust. This can be certificate from an authority or a self signed certificate. The javax.net.ssl.trustStore and javax.net.ssl.keyStore JVM properties are used to set this up.

cfdm.List¶
-
class
cfdm.
List
(properties=None, data=None, source=None, copy=True, _use_data=True)[source]¶ Bases:
cfdm.mixin.netcdf.NetCDFVariable
,cfdm.mixin.propertiesdata.PropertiesData
,cfdm.mixin.files.Files
,cfdm.core.abstract.propertiesdata.PropertiesData
A list variable required to uncompress a gathered array.
Compression by gathering combines axes of a multidimensional array into a new, discrete axis whilst omitting the missing values and thus reducing the number of values that need to be stored.
The information needed to uncompress the data is stored in a list variable that gives the indices of the required points.
NetCDF interface
The netCDF variable name may be accessed with the
nc_set_variable
,nc_get_variable
,nc_del_variable
, andnc_has_variable
methods.The netCDF variable group structure may be accessed with the
nc_set_variable
,nc_get_variable
,nc_variable_groups
,nc_clear_variable_groups
, andnc_set_variable_groups
methods.New in version (cfdm): 1.7.0
Initialisation
- Parameters
- properties:
dict
, optional Set descriptive properties. The dictionary keys are property names, with corresponding values.
Properties may also be set after initialisation with the
set_properties
andset_property
methods.- Parameter example:
properties={'long_name': 'uncompression indices'}
- data: data_like, optional
Set the data.
A data_like object is any object that can be converted to a
Data
object, i.e.numpy
array_like objects,Data
objects, and cfdm instances that containData
objects.The data also may be set after initialisation with the
set_data
method.- source: optional
Convert source, which can be any type of object, to a
List
instance.All other parameters, apart from copy, are ignored and their values are instead inferred from source by assuming that it has the
List
API. Any parameters that can not be retrieved from source in this way are assumed to have their default value.Note that if
x
is also aList
instance thencfdm.List(source=x)
is equivalent tox.copy()
.- copy:
bool
, optional If True (the default) then deep copy the input parameters prior to initialisation. By default the parameters are not deep copied.

The developer's version contains a link to the user's version (the "User's Documentation" hyperlink on the top left corner).
In general, the versions address difference is the "content-dev" vs "content" part in the URL.
You can hide any item (method or a remark part) from the user's version adding "!!!!!" (4 or more exclamation marks, 5 is recommended)
to the item text. It can be better to enclose them to the "mark" tag in order to highlight the text (e.g. <mark>!!!!! not work</mark>
).
If some section or overloads list became empty (all the methods are hidden), then the section or overloads will be hidden too.
For example, the Data_Object documentation does not contains the "Requirements" section in the user's version
because all the 4 items (remarks and 3 methods) are hidden.
You can exclude any page or directory from the user's version. To do this, create a ".doc-user-ignore" file in the doc source directory containing the file/directory, and add the file/directory name to the file (one name per line). For example, the "!doc" directory and "core/collection.js.html" file are excluded from the user's version.

Polymorphism is a tool in object orientation, which allows us to model behavior, while simultaneously leverage existing code. Polymorphism allows is behavior reuse. In C++ polymorphism, comes in 2 flavors, the standard runtime variant, and a curious compile time variant. Runtime polymorphism, like Java, leverages virtual functions to dynamically bind[1. With virtual functions the compiler doesn’t know which method to call until runtime. In C++ this is implemented with the virtual method table] a method at the call site. Compile Time polymorphism uses templates, to bind at compile time, thus negating the performance affect of virtual functions.
Polymorphism is a powerful concept. Polymorphism is a powerful tool in object-orientation, allowing one to realistically model the behavior or structure of some entity in software. This is key to any software design. Regardless, of idioms, language, paradigm, a realistic model is essential to a good design. If follow every best practice in software design, but your system doesn’t accurately reflect the real-world model, your software will be difficult to work with, and it will be impossible to bring new people on your project. An accurate portrayal is required.
C++ affords us 2 forms of g: compile-time [2. Compile-Time polymorphism is also known as static polymorphism. I, however find this nomenclature confusing. “static dynamicism”…. Um, what?], and runtime. Runtime is the most straightforward, and uses virtual functions. However, as we’ll see later, virtual function have their own performance costs.
We’re going to implement this very simple hierarchy, to demonstrate polymorphism is its most basic form.
struct Base {
Base (){}
virtual ~Base (){}
virtual void DoSomething(){
cout << "Hello From Base." << endl;
}
};
struct Child : public Base {
Child (){}
virtual ~Child (){}
virtual void DoSomething() {
cout << "Hello from Child." << endl;
}
};
Using the following driver code.
int main(int argc, char const *argv[]){
Base* b = new Child();
b->DoSomething();
delete b;
}
}
Produces the following output:
bash $ ./a.out
Hello from Child
This works, and its a familiar idiom. However virtual functions have a some performance issues. Since the call isn’t bound until until runtime, the methods cannot be inlined, and will probably incur a cache miss [1. A foo walks into a bar] , which on modern processors with the very deep caches is a very costly effect.
Secondly, even with cacheing aside virtual functions are about 2.5 times slower than direct function calls; where as inlining, i.e. zero-function overhead is about 20 times faster [1. How Slow Are Virtual Functions Really]. So this is a major issue is performance critical code, such as games. The EA directly states that virtual functions forbidden in their code [1. How the EA prevents Memory Leaks]. However, polymorphism is a powerful tool. Are we relegated to a “lower” form of Object-Orientation with writing performance critical code? No. In fact the opposite is true. C++'s template system is powerful and allows us to add dnasicm at compile time.
We can implement the same behavior as the UML figure above using templates. This improves the performance of our code in two ways. Firstly, by omitting virtual function we pickup a ~2.5x boost. Secondly, by using composition instead of inheritance we also get a small bump, and the compiler is more likely to inline the “inner” function.
template <typename ChildType>
struct Base {
Base (){}
virtual ~Base2 (){}
void DoSomething() {
myChild.DoSomething(); // This is the "inner" function.
}
private:
ChildType myChild;
};
struct Child /* Notice the lack of inheritance here */{
Child () {}
virtual ~Child(){}
void DoSomething(){
cout << "Hello from Child." << endl;
}
};
Our driver is similar to before, except for the instantiation. Instead of inheriting behavior from a base class and overriding it, the Child, or implementing type, is passed in as an instantiation argument. This creates a new type, which is the dynamic behavior we want. Using the following driver code, we achieve the same output as before.
int main(int argc, char const *argv[]){
Base<Child>* b = new Base<Child2>();
b->DoSomething();
delete b;
}
C++11 (-std=c++0x in gcc4.6) allows one 1 more improvement in the driver code to prevent memory leaks.
int main(int argc, char const *argv[]){
auto b2 = make_shared<Base2<Child2> >();
b2->DoSomething();
//Notice we don't have to call delete. Woot, exception safety!
}
So polymorphism is a powerful tool for creating dynamicism in programs, however with the inherent [1. Pun intended] performance issues the standard form of polymorphism is not the tool for every job. C++ templates allow use a manageable way to achieve similar behavior at compile time!

SINGAPORE: A 51-year old man was found dead after fire broke out in a Jurong West flat on Friday (Nov 8).
Police and the Singapore Civil Defence Force said they responded to the incident, which occurred in an apartment on the sixth floor of Block 516 Jurong West Street 52, at around 7.40am.
The flames were extinguished by police officers, who had arrived first, using a fire extinguisher through the living room window of the unit, SCDF said.
Firefighters later forced their way into the apartment through a bedroom window and found the man lying motionless inside. He was pronounced dead by an SCDF paramedic.
Police have classified the case as an unnatural death and investigations are ongoing.

Steve Belichick Freakishly Sounded Exactly Like His Dad After Latest Interview (VIDEO)
by Darrelle LincolnTo become great at anything, you have to put the time in.
To sounds like one of the greatest coaches in NFL history, apparently all you have to do is be born to the family and spend every moment around him for years.
Steve Belichick, who is the A Patriots safeties coach, did an interview on Friday and he creeped people out by sounding exactly like his father when speaking.
Steve is relishing the fact that he gets to spend more time with his father as an adult, because football kept him away at times growing up.
“Growing up under a football coach, you don’t see your dad as much as you would like to,” Steve Belichick said to Masslive. “So it was a total flip of the script. I went from not seeing him, seeing him once, twice a week to seeing him too many hours a day. So it took a little adjusting but I couldn’t be happier. We spend a ton of time together and it’s great to learn from somebody like that.”
“My dad is my role model,” Steve Belichick said. “He’s my idol. I’ve always looked up to him. I’m sure that influenced me getting to where I’ve come.
It’s nice to know that Belichick charm will be alive and well long after Bill retires from the game of football.

Event Location:
South Puget Sound Community College
2011 Mottman Road SW
Olympia, Washington
Abstract:
Do your users have the same old, mundane table reports they’ve been using for decades? Stop living in the past and make your reports pop. Learn to use design patterns, best practices and visuals that pack more usable information into fewer, more usable reports. Use Reporting Services and other Microsoft BI tools to create dynamic, browse-able reports that answer important business questions at a glance and then let business users explore the details to gain insight and take action. Sure, Business Intelligence is all the rage but you don’t have to invest in an entire BI platform to have fresh, usable reports.
Speaker(s): Paul Turley,
Abstract:
Most women working in technology keep a low profile, rarely standing out, rarely pushing the extra effort that typically denotes excellence. Women are constantly juggling to find the balance between career and family –with added complexity when children are involved. Come and learn about the three essential career considerations for Women in Technology. Understanding and applying these considerations can help you get to the next level of excellence in your career and family life. Men who understand these considerations can better support the women members in their life. I will share some of my own experiences, challenges, and lessons learned as I have learned how to balance career, family, and life in general.
Speaker(s): Sopheap Suy,
Abstract:
RLS (Row Level Security) is often integral part of EDW (Enterprise Data Warehouse) design. There are many ways to implement RLS. This is the story about our evolution of RLS implementation and how SQL-CLR integration helped us solve technical difficulty.
Speaker(s): Toshi Watanabe,
Abstract:
There are many IT pros who know all the snazzy tools to create fantastic reports. The users who know the data inside and out may not know those tools, but odds are that they know Excel. Microsoft has released PowerPivot which seems to bridge the gap between the two worlds. These power users can now create their own fantastic reports within PowerPivot. We will explore what PowerPivot is and how can use it to create a self-service business intelligence solution.
Speaker(s): Hope Foley,
Abstract:
Very large databases (VLDBs) are just like regular databases, right? There's just more of them to love. Working with very large databases can be difficult and tricky at times. Everything takes longer and minor issues become major very quickly. In this session you will learn some strategies for working with VLDBs such as how to speed up backups and restores, how to minimize your maintenance window requirements, and how to efficiently and quickly set up failover partners and replicas. Demos will include how I set up a log shipping secondary and a replica of a 2 TB database in less than half an hour.
Speaker(s): Robert Davis,
Abstract:
This session focuses on some surprising lessons learned and insights gained from applying DBA practices to relational data warehouses. Scenarios covered include use of table schemas versus synonyms, database chaining, managing user security, logical separation of user work from the data, backup and restore strategies, index maintenance, and change control.
Speaker(s): Ron Talmage,
Abstract:
A real life application of solving one companies serious production issues. This session will touch on many SQL Server tools, Third Party Tools, disciplines and resources and bring them all together into a synergy of useful index generation, and interpreting execution plans to get real performance measurements.
Speaker(s): Dale Cunningham,
Abstract:
Forget Profiler for a second, I have seen one poorly placed index bring an enterprise database to its knees. We will cover the basic tips of performance which always work and the ones which always fail. What can you do – and what should you do – when it comes to the most common types of indexes so you always make the right move. We will use lessons from SQL Programming Joes 2 Pros.
Speaker(s): Rick Morelan,
Abstract:
Scott's gentle introduction to SQL Server Integration Services (or SSSIS) will primarily be demonstrating how to you can use this tool in the real world to get work done. READ: very little PowerPoint time. SSIS is a high performance ETL solutions introduced in SQL Server 2005 to replace SQL Server's DTS functionality. ETL? It's okay, Scott will briefly cover some of these concepts too. Relax, sit back and learn how to simplify your "Extract, Transform, and Load" processes.
Speaker(s): Scott Stauffer,
Abstract:
A large majority of a modern DBA's workload consists of managing the resources on their systems in order to ensure that they are being followed and resources are accessible when needed. SQL Server 2008 provides Resource Governor, which allows the DBA to discretely manage system resources in a very structured way. In this session, we will show you how to configure, monitor, and administer these features as well as demonstrate some of the pitfalls and helpful hints that you will need in order to successfully implement this fascinating tool.
Speaker(s): Arie Jones,
Abstract:
"Through the Looking-Glass, and What Alice Found There" - When your world is SQL Server, you need a looking-glass to determine server health, diagnosis problems, and tune performance. In this session will we follow Alice through the looking-glass to determine what she finds in SQLServerLand. Alice will be using dynamic management views and functions (DMVs) to explore the land behind the looking-glass. She will find statistics, poorly performing queries, and much more. Follow Alice and her new friends, as she traverses across SQLServerLand and provides you with snippets of T-SQL code that you can use to explore your own SQLServerLand.
Speaker(s): Greg Larsen,
Abstract:
Replication in SQL Server is great tool for scaling out your master database(s) onto other servers for reporting and remote site access with near real-time data propagation. In this session, I will cover LAN and WAN data replication tricks-of-the-trade to offload work from your master servers. Using these techniques, you can improve your performance and monitoring of your existing installations or gain knowledge and confidence to implement new solution for your company.
Speaker(s): Chuck Lathrope,
Abstract:
Powershell is a very powerful management tool and you can spend hours writing magical scripts to do all the things you want. Frequently forgotten is the Powershell profile, a place you can add your own functions which can provide you lightening fast access to information. We'll talk about the power a profile puts at your fingertips.  I'll show you my Powershell profile if you show me yours.
Speaker(s): Nicholas Cain,
Abstract:
This session is written to help developers to read query plans, understand commonly seen operators and properties in the plan. at the end, I will explain how SQL Server estimates the cost of operators and how SQL Server make decisions to choose a plan out of numerous alternatives
Speaker(s): John Huang,
Abstract:
How can you get the most out of SQL Server Standard Edition? The SQL Server Enterprise Edition (EE) is far more expensive than the Standard Edition (SE). Many small office applications use SE. What features do you really need for your database system? Many features that are only available in EE, such as partitioning and data compression, are specific to managing larger databases. If you do not have very large databases, perhaps SE will be sufficient. Find out what actually improves performance for SE.
Speaker(s): Diane Robey,
Abstract:
The term “Cloud Computing” has become so polluted that it has come to mean “web”. How do you de-tangle all the hype and vendor terms and determine when and where you can use it? Buck Woody, a Senior Technical Specialist in Distributed Computing at Microsoft will explain your options – and describe the information you need to take back to your organization.
Speaker(s): Buck Woody,
Abstract:
Most modern enterprise database environments require some measure of auditing their data. Previously, the DBA would need to put together a complicated web of triggers and history tables in order to properly track data changes. Now in SQL Server 2008, Change Data Capture allows the DBA to readily enact a very straight-forward method for tracking the changes and understanding easily how they took place. In this session, we will examine how to set-up, configure, use, and administer the Change Data Capture process in your environment.
Speaker(s): Arie Jones,
Abstract:
We will describe some of the different architectures (focusing on the db side) that Microsoft Adserving has used to Load Balance ever growing user reporting loads, data refreshes, and database maintenance across multiple reporting servers. The focus will be on the DB side, with minor context given to the web and middle tier pieces necessary for each system to work. Note that this is reporting in the sense of generating end user reports (not using SSRS).

SneezingLike burping and farting, sneezing is simply one of those necessities that can take one by surprise in a variety of awkward situations -- at rest or at work, or even in the throes of passion. Yet just as mankind has long pondered the cause and mechanism of orgasm, so has it sought to explain the mystery of the sneeze. To most modern sneezers, it seems obvious that the primary function of the sneeze is to expel offending particles from the upper resperatory system, a cleansing mechanism. Likewise, ancient sneezers considered that the true function was to drive out evil spirits which had invaded the body -- more or less the same thing.The sneeze occurs when the nerve endings of the mucous membrane of the nose are irritated. This irritation then stimulates your trigeminal nerve, sending impulses through the trigeminal ganglion to a set of neurons located in the brainstem that collectively are termed the "sneezing center". These neurons send new impulses along the facial nerve back to the nasal passages and the face, causing the nasal passages to secrete fluid and become congested. The eyes may also tear. At the same time, the "sneezing center" also sends impulses to your respiratory muscles via the spinal cord. It is these impulses that create the deep inbreath and forceful outbreath, or the paroxysm of the sneeze itself. Meanwhile, the impulses travelling through the facial nerve happen to stimulate nerves which govern the reflex response we call the the blink. So, essentially, one message is sent, but two listeners receive it, and act on it. Hence the sneeze blink. Compare the "photic sneeze reflex," more commonly known as "sun sneezing", that strange phenomenon where people sneeze when suddenly exposed to bright light. Recognized in medical journals for the last 40 years, it has also been called the "ACHOO syndrome". Supposedly only 25% of the population is prone to sun sneezing, leading some to speculate that the tendency to sneeze at the sun may be an inheritable trait that only some possess. (It should be noted however that most newborns exhibit sun sneezing.) In 1888 the famous patent grabber Thomas Edison was quickly flipping through sequential pictures of someone sneezing when he realized that he could make a picture appear to move by showing a bunch of still shots in quick succession. So he assigned W.K.L. Dickson, one of his many assistants, to the task of inventing the necessary devices to record moving images (the "Kinetograph") and to play them back (the "Kinetoscope"). Edison and Dickson's discoveries launched a technological chain of invention that led to the cinema and all that supplanted it.

--- layout: post title: 'Caching: bypassing the Query Cache with cache tables' date: type: post published: false status: draft categories: [] tags: [] meta: _edit_last: '2' _syntaxhighlighter_encoded: '1' author: login: admin email<EMAIL_ADDRESS>display_name: admin first_name: '' last_name: '' ---
MySQL's query cache is a valuable tool. On a simple configuration, MySQL will attempt to store SELECT results in the query cache, so that subsequent, identical SELECTs get the data straight from cache, with no need to parse, validate, optimize and execute the query.
The query cache has its drawbacks, though. One of the most noticeable being the invalidation mechanism: once a certain table's data changes (by means of INSERT, UPDATE, DELETE), all queries which include that table in some form are invalidated, even if the change does not apply to them.
For example, using MySQL's world database, we wish to get those cities in the Netherlands:
SELECT * FROM City WHERE CountryCode='NLD';
The results of this query will, on normal settings, be cached in the query cache. However, the following query:
UPDATE City SET Population=Population+1 WHERE Name='Roma';
(Congratulations on Rome's newborn) will invalidate our Netherlands query, even though it does not affect its data. We further assume that City is a very large table, on which our queries are expensive, either because of locks or because of complexity.
Let us describe a way to bypass this invalidation scheme, using cache tables, triggers and stored procedures. Our solution is only targeted at a specific query or set of queries, and it is not a general solution to caching problems. The idea behind the solution, though, is general enough to be used elsewhere.
We will create the following table:
CREATE TABLE CityCache LIKE City;
The CityCache table is identical to City, and will only stored cache able data. Assuming we are interested in selecting cities by country, we offer the following stored procedure:
[code lang="sql"]DELIMITER $$
DROP PROCEDURE IF EXISTS `world`.`selectCityByCountry` $$
CREATE PROCEDURE `world`.`selectCityByCountry` (IN countryCodeInput CHAR(3))
BEGIN
DECLARE countCities INT DEFAULT 0;
SELECT COUNT(*) INTO countCities FROM (SELECT ID FROM CityCache WHERE CountryCode=countryCodeInput LIMIT 1) AS c;
IF countCities = 0
THEN INSERT INTO CityCache SELECT * FROM City WHERE CountryCode=countryCodeInput;
END IF;
SELECT * FROM CityCache WHERE CountryCode=countryCodeInput;
END $$DELIMITER ;[/code]
This procedure accepts one argument: a country code, and returns the cities in this country. Only it attempts to return the selection from the CityCache table. If the data is not there, it is INSERTed there from the City table first. For example, the following query:
call SelectCityByCountry('GBR');
Will find out that no British cities are listed in CityCache, INSERT into CityCache the relevant cities from City, then return those rows. Subsequent calls with the same parameters will read the data directly from CityCache. Moreover, CityCache table is as yet unaffected by changes to City itself.
Just one moment there! At current, queries performed from within stored procedures, and stored routines calls themselves are thoroughly disregarded by the query cache! So, what have we done so far? Have we created a cache table, which does not benefit from query caching at all?
Well, we just may wish to ALTER TABLE to ENGINE=MEMORY to make our queries super fast.
OK, how about invalidation, then? We'll use MySQL's triggers to invalidate rows in CityCache, in the following manner: any change to a city must invalidate all other cities in same country. By "change" we include adding, removing and updating. Here's the deal:
CREATE TRIGGER City_ai AFTER INSERT ON City
FOR EACH ROW
DELETE FROM CityCache WHERE CityCache.CountryCode = NEW.CountryCode;
CREATE TRIGGER City_bd BEFORE DELETE ON City
FOR EACH ROW
DELETE FROM CityCache WHERE CityCache.CountryCode = OLD.CountryCode;
DELIMITER $$
CREATE TRIGGER City_au AFTER UPDATE ON City
FOR EACH ROW
BEGIN
IF OLD.CountryCode != NEW.CountryCode
THEN DELETE FROM CityCache WHERE CityCache.CountryCode = OLD.CountryCode;
END IF;
DELETE FROM CityCache WHERE CityCache.CountryCode = NEW.CountryCode;
END $$
DELIMITER ;
Conclusion: following a problematic query invalidation issue, we have decided to completely avoid using the query cache and use our own cached table. Our smaller cache table is cheaper to use, and will only contains valid data, as copied from the original table.
