Consider the Nucleus
A Cellular Approach to CSS elements
2014-11-09
Antonie van Leeuwenhoek in the 1600's was the first person to discover the existence of single celled organisms, later on we would discover that these little, seemingly simplest kind of life are also what we're made of. Cells that is. Not prokaryotes, that would be silly. While we are big and complicated, we are made of (comparatively) simple and inarguably (unless you are a physicist) tiny things, heretofore referred to as cells.
The cell, (simplified greatly for the purposes of example and mortification of my mother) consists of the nucleus, empty space (queue angry mother), the cell wall, and then more empty space until another cell shows up. Now the particular geometry involved varies a great deal based on what thing those cells are making up, whether it's skin, neuron pathways or intestinal flume rides. But that rough pattern can basically be observed.
Now, after your kind patience I'll get into something I know considerably less about, page elements in an HTML document described by CSS. As I have come to understand it, each element has it's content, it's padding, it's border and it's margin. This happens to match quite closely with my previously described model of the cell. What are the odds?
A page element really ought to have content, and from the whole, interaction-centric, object oriented kind of take on thinking, it's basically what matters. So for both the cell and a page element, the nucleus and the content lay in the center, where things are most important. From there we have a barrier that defines inside and outside, this is the cell wall and the border, respectively.
But wait! Rarely is the cell wall touching the nucleus, likewise, there is padding between the border of the element, and it's content. More padding means more space between the border and the content. Now, margin is the weakest part of this metaphor, because while the space between cells is usually considered merely extracellular space and not particularly in the domain of one or the other, the margin space around an element is definitely it's own, defining where one starts and the next one ends.
Now what does thinking in this way garner us? Well, the geometry of organs is similarly applicable to the geometry of pages. Overall spacing and ordering of elements contributes to how, say, a gallery distinguishes itself from a block of text, or a chat room distinguishes itself from a message board.

--- layout: ad-layout title: Conway - A Tale Of 2 Young Men parent: Swipe - Ads nav_order: 22 ---
Advertisment
Dear Reader:
On a beautiful late spring afternoon, twenty-five years ago, two young men graduated from the same college. They were very much alike, these two young men. Both had been better than average students, both were personable and both—as young college graduates are—were filled with ambitious dreams for the future.
Recently, these men returned to their college for their 25th reunion.
They were still very much alike. Both were happily married. Both had three children. And both, it turned out, had gone to work for the same Midwestern manufacturing company after graduation, and were still there.
But there was a difference. One of the men was manager of a small department of that company. The other was its president.
Have you ever wondered, as I have, what makes this kind of difference in people’s lives? It isn’t always a native intelligence or talent or dedication. It isn’t that one person wants success and the other doesn’t.
The difference lies in what each person knows and how he or she makes use of that knowledge.
And that is why I am writing to you and to people like you about The Wall Street Journal. For that is the whole purpose of The Journal: To give its readers knowledge – knowledge that they can use in business.
You see, The Wall Street Journal is a unique publication. It’s the country’s only national business daily. Each business day, it is put together by the world’s largest staff for business-news experts.
Each business day, The Journal’s pages include a broad range of information of interest and significance to business-minded people, no matter where it comes from. Not just stocks and finance, but anything and everything in the whole, fast-moving world of business. . .The Wall Street Journal gives you all the business news you need—when you need it.
Right now, I am looking at page one of The Journal, the best-read front page in America. It combines all the important news of the day with in-depth feature report-ing. Every phase of business news is covered. I see articles on new inflation, wholesale prices, car prices, tax incentives for industries to major developments in Washington, and elsewhere.
The Journal is also the single best source for news and statistics about your money. In the Money & Investing section there are helpful charts, easy-to-scan market quotations, plus "Abreast of the Market," "Heard on the Street" and "Your Money Matters," three of America's most influential and carefully read investment columns..
Much of the information that appears in The Journal appears nowhere else. The Journal is printed in numerous plants across the United States, so that you get it early each business day.
Put our statements to the proof by subscribing for the next 13 weeks for just $28. This is the shortest subscription term we offer – and a perfect way to get acquainted with The Journal.
Or you may prefer to take advantage of a longer-term subscription for greater savings: an annual subscription at $107 saves you $20 off The Journal’s cover price. Our best buy -—two years for $185 - saves you a full $69!
Simply fill out the endorsed order card and mail it in the postage-paid envelope provided. And here’s The Journal guarantee: Should The Journal not measure up to your expectations, you may cancel this trial arrangement at any point and receive a refund for the undelivered portion of your subscription.
If you feel as we do that this is a fair and reasonable proposition, then you will want to find out without delay if The Wall Street Journal can do for you what it is doing for millions of readers. So please mail the enclosed order card now, and we will start serving you immediately.
About those two college classmates, I mention at the beginning of this letter. They graduated from college together and together got started in the business world. So what made their lives in business different?
Knowledge. Useful knowledge. And its application.
I cannot promise you that success will be instantly yours if you start reading The Wall Street Journal. But I can guarantee that you will find The Journal always interesting, always reliable, and always useful.
Sincerely,

Data Type: GIS Data Layer
Steward(s): U.S. Department of Agriculture, Natural Resources Conservation Service
Abstract:
Geoscience.Soils represents the extent of defined soil types throughout Utah. The dataset was created by digitizing maps, compiling information onto a planimetric correct base and digitizing or revising digitized maps using remotely sensed and other information. It is generally the most detailed level of soil geographic data developed by the National Cooperative Soil Survey.
Usage: All surveys areas have their own tables which are not interchangeable. All sets of tables are found at the NRCS Soil Mart.

The first episode in eight months. I’d forgotten how much I enjoy this podcast. Benjamin and Gruber could not compliment each other more perfectly. The last I heard Gruber was not so interested in recording more episodes, that was before number 30, I hope they keep it up.


Credits
- The text editor is a modded version of CodeMirror, which is crazy-awesome.
- This gif encoder library can be used to export tremendous animations.
- While the idea for this engine had been in my head for a while, I must have drawn some influence from Tom VII's highly original flash game, T in Y World.
- While figuring out the scripting language, I tried to port as many puzzle games as I could to the framework. Many of them didn't translate so smoothly - PuzzleScript, try as it might, isn't a general purpose game maker, not even really (yet) a general purpose puzzle game maker, but owes a lot in its design to the current generation of independent puzzle games.
- Documentation is all formatted with the highly functional Bootstrap. Thanks, twitter!
- I use the FileSaver.js library for saving files.
- The sound engine is a modded version of jsfxr, which itself is based upon sfxr.
- The default color palette used for names is a modified version of the magnanimous Arne's Generic 16 color game palette, with additional ones made in consultancy with Dock. Terry contributed the C64 one, and Jonathan Whiting contributed the whitingjp one.
- Thanks to my flatmate Terry Cavanagh for poking me to add a bunch of neat features which he nonetheless has no intention of using.
- I use QUint for unit tests. It was super easy to get going.
- I have an over-the-top pipline that compresses the website before uploading. It uses Google Closure Compiler (not the advanced mode, I couldn't get that to work) for compressing javascript, YUICompressor for compressing the css files, PNGCrush for compressing PNGs, Gifsicle for additional compression of the GIFs above what the javascript generator can do, inliner for generating the standalone template, and a wee bit of sed.
- The sharing framework is based around GitHub's fabulous gist-sharing api.
- Thanks to harry harrison for some tips/feedback about the html.
- Thanks to Jeff Roberts a bit, for being awesome.
Lots of testers/people who weighed in on the beta.

Hi everyone, I am a new user, my question is maybe too simple. Please make it lear for me.
Can you tell me how to find in the library or prove the simple theorem like:
theorem ttt1 (n m: ℕ ) : n <= m → n < m ∨ n = m :=
sorry
the naming convention would call that lt_or_eq_of_le
Thank you, but can you tell me how can find the stuffs like this one?
Is there a “search” command to find a theorem in the library?
I am working in some proof, sometime, it looks me quite a lot of time to find simple theorem to use.
For example, I need this one:
theorem tq (a b: ℕ ): ¬ a ≤ b ↔ b < a :=
sorry
Is there a way that I can find or prove it easily? I think it should be easy.
Thank you,
Truong
import tactic.find tactic.ring run_cmd tactic.skip #find ¬ _ ≤ _ ↔ _ < _ -- not_le: ∀ {α : Type u} [_inst_1 : linear_order α] {a b : α}, ¬a ≤ b ↔ b < a
@Truong Nguyen Mario already explained how to find stuff like this -- learn the naming convention :-) Follow the link!
Oh, thank you
Dear Kenny Lau,
Can you give some instruction for how to use the "#find" command?
import tactic.find def x := 0 -- or anything -- for some reason you can't use #find immediately #find _ + _ ≤ _ + _

Represents an interval of time where the time zone obeyed a certain UTC offset and DST delta.
The start of the interval is given by 'transitionTime' which comes from the TZ Database file. The actual start and until time of the interval (in the local time zone) is given by 'startDateTime' and 'untilDateTime'.
There are 2 types of Transition instances: 1) Simple, indicated by 'rule' == nullptr. The base UTC offsetSeconds is given by match->offsetSeconds. The additional DST delta is given by match->deltaSeconds. 2) Named, indicated by 'rule' != nullptr. The base UTC offsetSeconds is given by match->offsetSeconds. The additional DST delta is given by rule->deltaSeconds.
Some of the instance variables (e.g. 'isValidPrior', 'compareStatus', 'transitionTime', 'transitionTimeS', 'transitionTimeU', 'letter()' and 'format()') are transient parameters which are in the implementation of the TransitionStorage::init() method.
Other variables (e.g. 'startDateTime', 'startEpochSeconds', 'offsetSeconds', 'deltaSeconds', 'abbrev', 'letterBuf') are essential parameters which are required to find a matching Transition and construct the corresponding ZonedDateTime.
Ordering of fields are optimized along 4-byte boundaries to help 32-bit processors without making the program size bigger for 8-bit processors.

Mike Clark has written a provocative article entitled SwitchTower as an Automated Deployment Archetype in which he suggests that developers of all stripes ought to consider SwitchTower for their deployment system, whether or not they are using Ruby on Rails. I know I’ve heard at least one story of someone using SwitchTower to manage a PHP application. Anyone care to share any other success stories of SwitchTower managing a non-Rails application? Any gotchas potential users might want to be aware of?


\[ \newcommand{\epe}{\text{EPE}} \newcommand{\E}{\text{E}} \newcommand{\mse}{\text{MSE}} \newcommand{\tdata}{\mathcal{T}} \newcommand{\bias}{\text{Bias}} \newcommand{\var}{\text{Var}} \newcommand{\rss}{\text{RSS}} \]
We consider statistical model (for quantitative \(Y\)):
\[\begin{aligned} Y &= f(X) + \epsilon \end{aligned}\] and \(\E(\epsilon) = 0\). It is considered to be a useful approximation of the truth. Here \(X\) only affect \(Y\) through \(f\) and \(\epsilon\) is iid noise that is independent of \(X\). And extension of this model is to allow \(\var(Y | X = x) = \sigma(x)\). But still this is an oversimplification of the target model \(\Pr(Y | X)\).
For binary classification problem, we can have \(\E(Y | X = x) = p(x)\).
is it a very general rule? why using differences but not some other metric?
OK, let’s recall the problem setup. Suppose data is generated via \(y_i = f(x_i) + \epsilon_i\) for \(x_i \in \mathbb{R}^{p}\) and \(y_i \in \mathbb{R}\) (it could be a more constraint space). And we observe a set of training data \((x_i, y_i)\). The goal is to learn \(f\).
Usually we want to approximate \(f\) under some parameterization. Linear model is an example of it. Another example is linear basis expansions. \[ f_\theta(x) = \sum_{k = 1}^K h_k(x) \theta_k \] Essentially, a linear combination of some function form \(h_k\). For the examples of \(h_k\), it could be \(x_p^2, x_p x_q, \cos(x_p)\) or \(1 / (1 + e^{x'\beta_k})\) (for neural net).
Once we set it up like this, we want to minimize the residual sum-of-squares (RSS). \[\rss(\theta) = \sum_{i = 1}^N (y_i - f_\theta(x_i))^2\] to learn for the “best” \(\theta\).
A more general principle, other than minimizing RSS, is maximum likelihood estimation. For model \(Y = f_\theta(X) + \epsilon, \epsilon \sim N(0, \sigma^2)\), MLE is equivalent to minimizing RSS. For multinomial likelihood (for multi-class classification), the MLE principle leads to objective \[L(\theta) = \sum_{i = 1}^N \log p_{g_i, \theta}(x_i)\] (it is log-likelihood for multinomial and it is also called cross-entropy).

Hi !!! Here is a simple model to determine if the customer will churn or not.
INTRODUCTION Churn prediction is really essential for banks to determine whether the customer will leave the bank or not. Since customers are the most valuable assets to any company , it becomes imperative to build a strong model to predict their retention.The analysis obtained is a key business metric , because the cost of retaining existing customers is far less than acquiring a new one. In addition , long term customers provide more profit.
The model has been built on a existing dataset , where several features of the customer help to determine his/her churn status.The target variable is categorical in nature. [Y or N ]
This model has been built after testing different approaches like logistic regression , decision tree. The final model used is based on Random Forest.
This model provides good prediction with low error.
Easy to use model. Simply put in the numerical details of the customer in their respective domains and the model will predict churn status .


Registering allows you to create and save multiple lists of people. We'll also keep track of who's been picked so they'll have less of a chance of being picked next time!

MDW stands for Model Driven Workflow. It's a CenturyLink-developed business process management system (BPMS) framework. A high-level summary of the BPM features offered by MDW is available here: http://cshare.ad.qintra.com/sites/mdw/bpm.
A business process is a defined set of business activities that represent the steps required to achieve a business objective. It includes the flow and use of information and resources. These are generally represented at a high level, so as to be understood by the users and managers of the process. Examples of business processes include:
Business Process Management (BPM) is the concept of shepherding work items through a multi-step process. The items are identified and tracked as they move through each step, with designated users or applications handling the information.
Business Process Management System/Solution/Suite (BPMS) does not have a standard definition, but generally refers to tool sets that facilitate the following BPM activities:
A process in MDW is used to model a business process. Fundamentally it consists of a number of (automated or manual) work items or steps, called activities, which should be performed in a designated sequence. A process can invoke another process through a subprocess activity. Transitions are the links between activities that model dependencies between steps, so that when an activity is completed, the process flows through one or more outbound transitions to start other activities that depend on completion of the first. In more formal words: a process is a collection of activities and transitions between those activities, and is mathematically and graphically represented as a (typically acyclic) directed graph.
One of the benefits of a defined business process is that it can be applied repeatedly to many data instances. We use the terms process definition vs. process instance to differentiate between the template that describes the process and a particular execution of that process. Similarly, an activity instance is the execution of an activity within a process instance, and a transition instance is a transition actually traversed within a process instance. When the context is clear, we often simply use the term activity to mean activity definition or activity instance; similarly for the terms process and transition.
Along with process definitions, many other types of design-time artifacts are maintained in MDW. These include such things as Business Rules, Reports, Templates, etc., and are collectively known as workflow assets. MDW provides a distribution mechanism to encourage reuse of workflow assets. The MDW framework base distribution offers a number of commonly-used asset categories. Optional MDW extension packages include assets related to specific domains (such as Camel, Reporting, and a host of others). In addition, many workflow teams have contributed asset libraries that are discoverable through the standard MDW distribution mechanism.
Activities are implemented in MDW by Java classes, called activity implementors. To allow a single activity implementor to be reused in many places, it's typically designed to allow configuration through a set of attributes (name value pairs). For example, a web service adapter activity can take an endpoint URL as an attribute, allowing it to be used in multiple places where it connects to different service providers. In a workflow process, an activity definition therefore includes the specification of which activity implementor to use and the configuration of its attributes. The MDW framework makes it easy to extend the available set of implementors with application-specific ones, which are treated as first-class citizens alongside the prebuilt implementors. These in turn can be shared through the asset discovery mechanism described above.
For holding runtime data, a process is usually associated with a set of variables. A variable has a name and will be give a specific value at runtime. The value of a variable is constrained to a given type declared when designing the process. A design-time variable representation is more formally called a variable definition which defines a name and type but not a value, whereas its runtime instance is called a variable instance, which holds the value corresponding to a specific owning process instance.
Documents are special types of variables that can hold large data values such as XML documents or Java objects. These are passed by reference to avoid keeping multiple copies.
A task is an activity meant to be performed by a person. To avoid confusion we often use the term manual task since task is used in some BPM products to express the more general concept that we call activity (both manual and automated) in MDW.
A task manager is a (typically web-based) user interface enabling users to perform many functions related to manual tasks. Examples include:
In MDW the task management UI is known as MDWHub. Tasks relate back to the process definition through manual task activities. The definition of a task is called a task template. This represents design-time aspects (such as Due Date and Notification recipients), whereas a task instance is a runtime line item in MDWHub that contains specific data and is assigned to a designated user for completion. The data captured in MDWHub feeds back to the process instance, and can be used for runtime branching and decision making. A special type of task may exist without reference to any workflow process. This type of task is called an ad hoc task, which will be covered later.
At this point, you may want to see what MDW looks like in action.
From a code organization perspective, MDW provides a framework that can be customized through configuration and scripts as well as extended with custom activities and event handlers, which are implemented in Java. The following diagram shows the major components of MDW and workflow applications built on top of MDW.
The MDW Framework contains the following major components:
MDW (and workflow applications built on MDW) can run on a number of supported server containers, and use an Oracle or MySQL database for storing both runtime data. The core of MDW uses the servlet API of the container and can optionally take advantage of other container provided features such as JMS, transaction management, database connection pools, thread pools, OSGi, clustering, e-mail, etc. Specialized MDW adapters and listeners for licensed, third-party protocols such as Tibco Bus and MQSeries depend on corresponding server-side installations (but these are required only when an adapter or listener is actually utilized by a workflow app).
MDW supports a number of different extensibility models:
This section is intended for project managers, development managers, and technical leads. The following steps are typical for using MDW Framework to develop applications, using stand-alone application model:
MDW Core Team not only provides training but also acts as "professional" services along the way, to assist the development team in all cycles of development. The development team should in general add 10% to the estimate of development hours for MDW Core team to provide the service as well as for developing new MDW enhancements.
 The designer should be used as the tool to facilitate requirement gathering and communication between clients, system engineers, analysts, and development leads. The development will continue by enriching the information in the designer, resulting design and implementation.
Therefore, during process design stage, the participants will be clients, system engineers, analysts and development leads, and the output will be high level processes with documentation of activities (but without implementation details). At this stage, we can use any activity as place holder (you probably want to avoid using activity with obvious special meanings such as start and stop activities) and simply document the requirement for the activities. Right-click on any activity and select "Document" menu item (or simply press Control-D while the activity is selected) to open up documentation dialog for the activity.
For interfaces with external systems, the documentation dialog allows to specify hyperlinks, which should be used to point to interface specification documents, such as XSDs.
For manual tasks, we can use GUI builder to create mock up screens. To be implemented: when printing out requirements, print out screen as well.
Use embedded processes for exception handling, time out handling, request modification and cancellation handling.
Once the requirements are agreed upon, we can start to move down to next stage on low level design. The participants at this stage is typically the entire development team, driven by the development lead. Low level design involves typically the following steps:
MDW provides several tools to help with testing, including an automated workflow tester, adapter stubbing capability, and an API for unit-testing workflow activities. MDW Designer also provides runtime process instance view which is proven extremely valuable for troubleshooting in both testing and production environments.
Besides runtime process instance view, MDW provides easy to use/read logging mechanism which logs information on to standard output and files.

To be distributed: standard Sentry configuration file
A process is typically started by one of the following means:
Business processes are often long running, lasting days or months. Therefore, if a process is started in response to an external event (a message from an external system), the external system does not wait for the process to complete and at most obtains an acknowledgment that the process is indeed started. In another word, processes are typically started asynchronously.
MDW processes can also be used to implemented services, in which case the external system is waiting for a response in real time. Such processes are executed synchronously, and are called service processes. We will call processes executed asynchronously regular processes. Unlike regular processes, service processes typically have strict performance requirement, as the external system is waiting for responses. Because response time may be crucial for service processes, MDW 5.1 currently supports 10 different performance levels. Earlier versions of MDW support three levels. See Processes for details.
There is another type of processes, called embedded processes, which are embedded in regular processes. Embedded processes are used to model handling of exceptional events, and have the following types:
MDW also supports remote process invocation and hence federated workflows. A process in an MDW application can directly invoke another process hosted in a different MDW application as a remote subprocess. The designer can display remote process instances in pretty much the same way as local process instances, thereby allowing the user to drill down from the main process to all subprocesses (remote or local) without swiveling to different designers. The main constraint is that the designer cannot make changes to remote processes or process instances (anything from remote application can be accessed read-only)
Parameter passing is also done pretty much the same way as local subprocess invocation. Document variables are passed down as references, but they are read-only as well.
MDW distribution comes with set of out-of-box activity implementors for common tasks. Each of the out-of-box activity implementors has documentation on how to configure it.
The following is a list of out-of-box activities and the hyper links point to their documentation:
| Implementor | Description |
|---|---|
| Process start activity | This is the first activity any process executes |
| Process stop activity | Stop the process. |

In general, developing an activity implementor involves two steps: creating a java implementor class (most often by extending an out-of-box implementor), and making it available in the designer. Refer to Introduction on Developing Activity Implementor for more detailed description on this topic.
Application implemented activity implementors should also be implemented in such a way that it allows configuration and comes with documentation, to allow reusability.
An adapter is an activity used to send messages to external systems, and receive responses if the communication protocol is synchronous. If the business logic expects an asynchronous response for a one-way message sent to external systems, the listener framework to be introduced later will be used to listen to the responses (as external events) and notify an event wait activity waiting for the responses.
The above out-of-box activity list contains quite a few generic adaptors for common transport protocols, including JMS adaptor, Tibco bus adaptor, MDW web service adaptor, Axis based web service adaptor, RESTful web service adaptor, MQ Series adaptor, LDAP adaptor, etc. It is typical for applications to extend these generic adapters to implement external system specific adapters.
These protocol specific out-of-box adaptor activities are very simple to use. This simplicity, while allowing rapid learning and prototype, may lack manageability needed in a production environment. The connection pool mechanism, while slighly more complicated, adds the following features for supporting production environments:
There is a single out-of-box activity, connection pool adapter, that can be used directly or extended to send messages through connection pools. We call those adapters connecting directly to external systems direct connection adapters. Connection pools use poolable adapters, which are adapter activities implemented in a new way introduced in MDW 4.5.12 and MDW 5.1.05. Refer to Using Adapter Connection Pool and Using Adapter Activities for information on how to configure connection pools and on how to implement (poolable) adapters.
One of the most common reasons for implementing new activities is to define adapters specific to some external systems. Refer to Using Adapter Activities for more detailed description on this topic. You may also need to refer to the documentation for the specific type of adapter you are to extend.
Although connection pools and direct connection adapters can be used to automatically re-send messages on conneciton failure, JMS is the preferred way for implementing certified messages, which not only garantees the messages are delivered but also ensures the messages are delivered no more than once. Introduction to certified messages is covered under JMS Adapter documentation. The certified messages through JMS, however, require both the sender and the receiver are MDW applications (4.5 for MDW 4 and 5.1 for MDW 5), because they require hand-shaking between the sender and receiver to ensure the messages are acknowledged and delivered exactly once.
When the receiver is not an MDW application, it is not possible to implement a general certified mechanism. With the help of a little bit of custom coding (in adapters), the connection pools can be used for the next best thing - it can ensure the messages are delivered by automatic retrying, but it cannot ensure the messages are delivered no more than once. In practice, this is sufficient in most of time, especially that it does not require receiver to be MDW-based applications.
We note that the certified messages addressed above refer to MDW implementation on top of underlying transport protocols. Some transport protocols support certified messages natively, and when you use those features, you do not need to use MDW implementation. However, we found in most cases the applications are not able to use native certified messages for various reasons:
Messages received from external systems (other than those as synchronous responses to messages sent to external systems) are called external events. We note that MDW engine uses messages internally to execute processes, and these messages are called internal events.
The entities receiving external events directly are called listeners. Because the transport protocols can vary, and the message formats are typically different, listeners in MDW typically performs the following tasks:
Listeners are the only protocol-specific code components, and they perform minimum amount of work and often contains less than 100 lines of code. Event handlers and the listener helper are all protocol agonostic. MDW provides listeners for many common protocols out-of-box, such as JMS, Tibco Bus, RESTful webservice, MQ Series, MDW SOAP web service, EJB. MDW applications rarely need to define their own listeners.
The listener framework assumes the external events are all XMLs. Through MDW Designers, the applications use XPath to configure which external event handlers to handle the messages (root element tag is just a special case for XPath).
An external event handler is a Java class, and it may may perform one of the following main functions:
This is implementor java class name is
com.centurylink.mdw.listener.jms.JmsListener
,
and the JMS queue JNDI name is com.centurylink.mdw.external.event.queue
.
The URL for external systems to send messages is t3://host:port
.
The listener will send back a response to the invoker if the ReplyTo queue is specified in the message, and the external event handlers return non-null responses.
The JMS listener supports certified messages by acknowledging the messages automatically and ensuring a message is processed only once.
This is implemented as a bus processor supported by Qwest-developed bus connectors.
The java class name is com.centurylink.mdw.listener.tibco.MDWBusListener
.
You will need to configure Tibco bus listener (to be completed)
You can configure more than one listeners, each for for a different subject.
Note that the bus connectors manage their own thread pool.
This is implemented as a servlet. The java class name is
com.centurylink.mdw.web.servlet.RestfulServicesServlet
,
and the URL for external systems to send messages has the form
http://host:port/MDW Web context root/Services
.
This is a general-purpose SOAP listener for exposing document-style services whose WSDL is stored
as a workflow asset. The URL for the
WSDL is http://host:port/MDWWeb/SOAP/AssetName.wsdl
.
The listener is implemented as a servlet that unwraps the payload from the SOAP Envelope and passes
it on as the master request.
This is implemented using native IBM MQ Series Java API, rather than
using WebLogic foreign JMS. The java class name is com.centurylink.mdw.listener.mqseries.MDWMQListener
.
You will need to configure MQ listeners to be completed
MQ Listeners mananges its own thread pool.
The java class (EJB) to implement this listener is com.centurylink.mdw.workflow.engine.DesignerServerBean
.
The JNDI name for accessing it is com.centurylink.mdw.workflow.engine.DesignerServer
.
The JNDI server URL has the form iiop://host:port
.
The method to use is
String sendMessage(String protocol, String message);
where protocol must be "Ejb"
and message
is the actual request message, typically an XML string.
MDW provides two commonly used external event handlers out of box,
one for starting processes (com.centurylink.mdw.listener.ProcessStartEventHandler
)
as well as invoking processes as services,
and the other for sending messages to existing process instances
(com.centurylink.mdw.listener.
).com.centurylink.mdw.listener.NotifyWaitingActivityEventHandler
These out-of-box listeners are often sufficient for most applications. Sometimes it may be necessary for an application to provide their own external event handlers for performing customization not achievable through the out-of-box ones.
The external event handlers (including the out-of-box ones) must be configured through the Designer so that the listeners know which one to use for an incoming message.
to be completed: how to use the two handler, and how to configure event wait activity.
to be completed: a third out-of-box event handler,
com.centurylink.mdw.listener.NotifySynchronousAdapterHandler
,
is needed to notify composite synchronous adapters within
a service process (required for service processes running in memory-only mode).
Refer to Listeners and External Event Handlers for description on how to configure external event handlers
Refer to Listeners and External Event Handlers for more detailed description on this topic.

We already mentioned that MDW task manager also supports tasks that are not related to activities, independent from processes, and such tasks are called independent tasks. The most common usage of independent tasks is to start a process. Such tasks are also called pre-flow tasks, as they exist before the corresponding process instances are created, and the process instances are created only at the completion of the pre-flow tasks. In contrast and when it needs to be emphasized, we call tasks associated with task activities in-flow tasks.
Being the user interface components, tasks have model, view and control aspects.
MDW uses Java for embedding dynamic values.
Task activities are configured in the designer, just like
any other activities. Follow this link
for details on configuring autoform manual tasks, and follow
this link for
details on configuring custom manual tasks. In summary, you will need to configure the following items: MDWHub is the web front-end for the users
and administrators to perform and manage manual tasks.
It supports common functionalities such as task searching,
task summary view (list of tasks based as the search result),
task detail view (view details of a single task),
user and group management,
quick links (most commonly used queries such as "My Tasks").
The
MDWHub User Guide describes end-user functionality, whereas
MDWHub Development discusses customization techniques. MDWHub uses ClearTrust single-sign-on based on LDAP credentials. For authorization control, MDW employs the concepts groups and roles.
The following highlight the scheme: We have introduced above different ways to customize detail views
and actions of a task. It is also commonly needed to customize
common functionalities of the MDWHub such as summary view,
user and group management,
queries and quick links, etc. MDW provides
several ways to support such customization:Configure Task Activities
MDWHub
Process Design
: can create and modify process definitions
and other workflow assets owned by the group.Process Execution
: can execute processes and manage/alter
process instances of process definitions owned by the groupTask Execution
: can take actions on manual tasks that
are associated with the group.User Admin
: can add/delete users to the group and grant roles.Supervisor
: can act on behalf of other members of the group;
can assign/reassign tasks when other members are not allowed.Site Admin
is a special group that is the parent of all other groups without
specifically designated parent groups. Hence any user who is a member of this group
will have the roles defined for this group carried over to all other groups.Common
group, of which any user is a member. Process
definitions and other workflow assets owned by this group can therefore be seen
by all users.Customizing MDW Hub
mdw-hub-view.xml
.
Basic customization such as adding a column to the summary view
can be achieved this way. The details can be found
under MDWHub Development.
Starting from MDW 5.1, the MDW task manager is separated from the workflow engine, so that multiple workflow applications can connect to the same task manager that is hosted by another (may be dedicated) MDW application. This is to allow users to access one task manager for any workflow tasks, and to allow managing users, groups and roles in a centralized location. If an MDW application uses a centralized task manager (or any MDW task manager not hosted in the same application), we will refer to such task managers as remote task manager. When it needs to be emphased, we call the MDW task manager coupled with the engine in the same application the local task manager.
Because MDW engines communicate with task managers through messages, using the API introduced here, they can also communicate with non-MDW task managers as long as as long as they implement the same task manager API. We will call such task managers as foreign task managers.
Because detail view of task instances and actions to be performed on these tasks are closely related to the workflow application, when a remote task manager is used, MDW allows to display task detail views still in local task managers, and the remote task manager displays the task summary views and link seamlessly to the detail views hosted by individual applications.
Two properties need to be set for the engine to use centralized or foreign task manager:
mdw.taskmanager.jndi
- this is the JNDI for the task manager server
JNDI provider, and it needs to be set in the form
t3://host:port
. We have not tested non-WebLogic
provided JNDI servers as of now.mdw.taskmanager.queuename
- this is the JMS queue name of the task manager.
If you do not specify this property, the engine will use com.centurylink.mdw.external.event.queue
,
which is the queue name for MDW-provided task manager.The communication between MDW engines and task managers is through standard external event infrastructure MDW supports, namely it can be any common protocol such as JMS, WebService or Tibco Bus. The preferred is JMS, which is used when the task manager is MDW-implemented.
Scheduled jobs are jobs to be run at scheduled times, typically repeating periodically. A typical usage is to start a process periodically (e.g. at the same time every day), and another is to run MDW database clean-up script periodically.
Besides items such as processes, activities, transitions, and tasks, MDW also employs quite a few other types of resources to support definition and execution of business processes. These resources are collectively called workflow assets. Historically they are called scripts or rule sets, as scripts and rule sets were the first types of assets, and the assets are all stored in the database table RULE_SET for that historical reason. For the same reason, resource types are often called languages. The following table lists all the workflow resource types supported as of MDW 5.1.04.

The property manager loads properties in the following sequence (if a property is defined in more than one place, the one loaded latest overrides the previous one, effectively making the later loaded property file the higher precedence):
mdw.properties
in the application's configuration directory
(this is typically the Qwest/config
directory under the domain,
or deploy/config
in the application development
directory for cloud development environment).
This file contains properties used by MDW components and is distributed
along with MDW application. The application should not typically modify
this file.application.properties
in the application's
configuration directory. This file should contain application specific
(non-MDW) properties, as well as MDW properties that override those
in mdw.properties. MDW distribution does not include this file,
and it should be created by the application when there is a need.env.properties
file in the application's configuration directory. This is intended
for use in development environment only, to provide local override.Prior to MDW version 5.1.08, ApplicationProperties.xml (which is in XML format rather than standard Java property file format) was used in place of mdw.properties and application.properties files.
MDW Framework supports server clustering for load balancing and fail over, most often through the underlying servlet containers. Because MDW and its applications are mainly workflows rather than web applications, the clustering needs are different - instead of or in addition to http proxies that are used for clustering web sessions, MDW requires load balancing and fail over for internal and external messages. Indeed, it is recommended not to use session replication feature of HTTP proxies for MDW applications. The following table lists the key features and how they are implemented and configured for the containers.
mdw.server.this
.mdw.server.list
.mdw.proxy.server
. If no proxy is configured,
MDW uses the internal round-robbing algorithm just like the one for RMI internal messaging.
Similary, the proxy for WebLogic servers is used for clustering, although
with the current deployment model in ECOM, we will need
to make sure the internal messaging URL is excluded from clear trust interception
(for single-sign-on).mdw.server.list

MDW uses BIRT for its reporting engine. Reports can be written against the MDW runtime database for summarizing high-level information about processes and tasks. Refer to MDW Reports for more details.
MDW engine is also designed to work with BAM (Business Activity Monitor). Refer to BAM for more details.
Order life cycle management is a broad area where business processes are extensively involved. It is therefore not surprising that more than half of all installed MDW applications fall in this area. We devote this section introducing general architecture for order management using MDW and MDW-based applications. The following figure depicts this architecture at a high level.
The creation of orders start in order entry systems such as Consulting Plus, Ensemble and IOE. These systems may invoke many services to collect information for order creation, such as:
Implementation of these services may involve accessing multiple source systems, and any reservation may result needs for un-reservation. The service processes of MDW provide desired functionality as well as tunable performance levels to balance response time requirement with traceablity. As MDW is relatively new in this area, it is currently only used in some nitch areas for pre-order services.
Once an order content is completed, it should be submitted to workflow systems to manage its entire life cycle until the order is fulfilled (provisioning is completed) and the billing system is updated. All orders should (but not yet) be submitted to Integrated Order Management (IOM) workflow, which is an MDW based workflow and responsible for decomposing the order into product-specific components and invoking corresponding subworkflows. We sometime refer to IOM as the macro workflow, whereas product specific workflows as micro workflows, although there is really no reason to limit the hierarchy to just two levels. Besides top level order decomposition, IOM provides orchestration between micro workflows. For example, IOM may need to ensure billing process not started until all products are successfully provisioned; it may need to start layer 2/3 provisioning processes only after layer 1 provisioning processes have been completed.
Unlike some commercial systems such as OSM, MDW or IOM do not provide out-of-box order decomposition functionality. Instead, MDW/IOM relies on an (any) external rules engine to decompose an order into an execution plan (which is an XML file describing what subprocesses need to be launched), and MDW has an out-of-box activity that can launch multiple heterogeneous subprocesses based on the execution plan. Even though out-of-box order decomposer such as the one in OSM does well as showcase, MDW architecture is simple yet flexible and has the following advantages:
Another important component for order management is Order Services Repository (OSR). In an ideal world, we should have just one database for storing service orders. For historical reasons, CenturyLink has several major order databases (SOPs, PROD, Ensemble and IABS) with many minor ones. Most of these are not easy to access and are certainly not designed to work with a BPM system like MDW. OSR is designed for mainly two major purposes:
Detailed introduction to OSR can be found in Service Order Repository - High Level Design
BAM (Business Activity Monitor) that we introduced above is also an important component in order management architecture, as it provides a central place for tracking orders from end-to-end.
Handling supplemental orders (cancelling or modifying orders after they are submitted but before they are completed) is an important task of any order management systems and typically the most complex one. MDW provides support in the following ways to assist supplemental order handling:
You can override the MDW property manager by your own. First, you need to create y
our property manager, which must be a java class implementing the interface
com.centurylink.mdw.common.utilities.property.PropertyManager.
You can use the default MDW property manager
com.centurylink.mdw.common.utilities.property.impl.PropertyManagerDatabase
as a sample, or better subclass from it, as you may need to use the methods in that class.
Secondly, you will need to direct your application to use this property manager instead
of the default one. This is done through Java system property
property_manager
. For example, you can set the property

Tønsberg is a vibrant city with a lot going on in the summer. It is one of Norway's oldest towns.
Position 59° 16'15"N, 010° 23'44"E
You can practically tie your boat up to any one of several outdoor restaurants or go to the guest harbour a bit further west for peace. The guest harbour can get a bit uncomfortable, but not dangerous in a strong SW. Avoid the outside of the pontoons if possible.
There are also many new local marinas on the approaches to the canal.
The new bridge opens 5 minutes before the old bridge for E-bound and 5 minutes after old bridge for W-bound vessels.
The marked channel SE of Tønsberg canal continues through a huge expanse of quite shallow water. There are extensive charted anchorages south of this marked channel at Træla.
