Project Goal:
Travel Time Calculator. This application would calculate travel times in a vehicle, on bike, or on foot showing the user a radius of where they could get to in a specified time. This solves a traffic engineering problem that includes calculating FFS, LOS, distance, and temporal variation of traffic. We could add to this, for example it could calculate the population living within a certain travel time to predict trips that could be attracted to an area, or it could show an elevation profile along a line drawn to help walkers/runners/bikers pick the best 10 minute path, it could populate a list of known places/locations within a given time like stores, government buildings etc.
From an engineering standpoint this could be a critical tool for transportation planners and traffic engineers to get instant feedback on the market area of a new development. It could be used as a PR tool to help the community see what is available to them nearby. Typically this kind of analysis is run on complex GIS modeling software and is available to very few people. We believe that if this information could be more readily shared across the region and help decision makers to make informed decision that will improve the transportation infrastructure of the city.
Required Vector and Raster Analysis: Some sort of network analysis will be required for the vector data, which consists of roads. Travel times for bicycles could be estimated using raster analysis when considering slope.
Data:
Geoprocessing Workflow: Calculate travel times based on speeds from existing traffic conditions and speed limits and use the network analyst tool to create a series of polygons that connect routes based on travel times. Travel times for bicycles could be calculated factoring in slope, which would use the slope tool with some DEM data.
User Interface:
How the Code will be Stored:
The code will be stored using a newly formed Github account named: BYU Geoid. A strong emphasis will be placed on providing simple and clear instructions for the user on the Github page.
License: This application will be given a generic open source licensing agreement with no proprietary claims.
Project Responsibilities:


THIRTEEN DAYS (New Line) Starring: Kevin Costner, Bruce Greenwood, Stephen Culp, Dylan Baker. Screenplay: David Self, based on "The Kennedy Tapes - Inside the White House During the Cuban Missile Crisis" by Ernest R. May and Philip D Zelikow. Producers: Kevin Costner, Kevin O'Donnell, Peter O. Almond and Armyan Bernstein. Director: Roger Donaldson. MPAA Rating: PG-13 (profanity, adult themes) Running Time: 138 minutes. Reviewed by Scott Renshaw.
In an early scene in THIRTEEN DAYS, Kenny O' Donnell (Kevin Costner) sits at the breakfast table with his wife and children. It is October 1962, and O'Donnell is a special advisor to President John F. Kennedy (Bruce Greenwood). As the conversation turns to field trips and report cards, alarm bells begin going off. Not literal alarm bells for some civil defense drill -- metaphorical, artistic alarm bells for viewers with a sense of deja vu. This is a film about the Cuban Missile Crisis, but here we are with a crew-cut Costner in his domestic glory. Will THIRTEEN DAYS, like JFK before it, make the mistake of looking at a pivotal moment in American history and asking, "How did it affect Kevin Costner's fictional family?"
Then, for most of the film, something wonderful happens: We see no one but men in suits, trying to solve a seemingly unsolvable problem. As tautly directed by Roger Donaldson, THIRTEEN DAYS finds riveting drama in passionate debate, tricky politics and impossible decisions -- at least until the O'Donnell kin start turning up again. Most of the narrative is spent in the war rooms and strategy sessions that find JFK and his key advisors -- O'Donnell, his brother and Attorney General Bobby (Steven Culp), Secretary of Defense Robert McNamara (Dylan Baker) -- trying to determine the appropriate course of action after spy planes identify Soviet nuclear missile sites under construction in Cuba, just a couple of weeks away from being functional. Do nothing, and doomsday is a five minutes flight from half of America. Try diplomacy, and the sites become operational while offers and counter-offers take place. Sneak in to attack the sites, and the Soviets retaliate in Europe, setting off a likely World War III.
THIRTEEN DAYS is a history-based thriller that faces a variation on the knuckle-headed joke promulgated by the anti-TITANIC contingent: In this case, we know the boat (or the human race) _doesn't_ sink. But THIRTEEN DAYS isn't about whether or not the world will be bombed to cinders; it's about the astonishing real-life war game played by capable but flawed people for the fate of civilization. For a film that is devoted largely to debate and description of scenarios, THIRTEEN DAY is incredibly tense. We watch politicians go toe-to-toe with soldiers over the appropriate philosophical footing for dealing with the Red Menace. We watch brinksmanship played like two kids shoving each other on a schoolyard. It's the kind of smart film-making of ideas that can keep you on the edge of your seat waiting for a phone to ring, or not to ring.
Mostly, however, it's a profile in the courage under fire of John F. Kennedy. Plenty of films have opted either to canonize JFK as our great slain king or demonize him as a womanizing rich kid, but I don't think any film has ever made him as compelling a dramatic character. As played with a piercing intellect by Bruce Greenwood, Kennedy is portrayed as an often short-tempered man with burdens to bear (the subtle acknowledgement of his chronic back pain is one of many effective shorthands in David Self's script). He's also the essence of a great leader, bringing the finest minds together, considering the greatest possible good and finally trusting his own reason and judgment. Greenwood's dynamic performance finds JFK's legacy not in some legend of golden boy heroism, but in the idea that he carried out his responsibilities with character.
All is exceedingly well in THIRTEEN DAYS until the story begins drifting back to O'Donnell fretting over his loved ones. Costner is a much-maligned dramatic actor, and he doesn't do himself favors here with a honking Boston accent that's borderline absurd next to the subtler intonations of Greenwood and Culp (as scary a dead ringer for RFK as you could imagine). When one scene after another in the final half hour of THIRTEEN DAYS finds Costner staring pensively at one of his children, sharing a quiet moment with his wife or rubbing his tightly-closed eyes, it becomes too easy to lose focus on the big picture for some misguided sense of "humanizing" the story. There are plenty of dramatically fascinating humans in THIRTEEN DAYS without ever leaving the closed conference rooms of the White House and the Pentagon. Policy can make surprisingly intense cinema, without a breakfast table or report card in sight.
On the Renshaw scale of 0 to 10 hits and missiles: 8.

They then leave and sell their KMD or refuse to buy any...even after literally just coming to the conclusion that KMD is undervalued with huge and still realistic growth potential...

--- layout: post tags: [Dependency Injection, Software Design] date: 2013-01-09 10:42:20 UTC title: "Metadata Role Hint" description: "This article describes how object roles can be indicated by metadata." --- {% include JB/setup %}
{{ page.description }}
In my overview article on Role Hints I described how making object roles explicit can help making code more object-oriented. One way code can convey information about the role played by an object is by leveraging metadata. In .NET that would often take the form of attributes, but you can also maintain the metadata in a separate data structure, such as a dictionary.
Metadata can provide useful Role Hints when there are many potential objects to choose from.
Consider a web shop. When you take your shopping basket to checkout you are presented with a choice of shipping methods, e.g. Standard, Express, and Price Saver. Since this is a web application, the user's choice must be communicated to the application code as some sort of primitive type. In this example, assume an enum:
public enum ShippingMethod { Standard = 0, Express, PriceSaver }
Calcucating the shipping cost for a basket may be a complex operation that involves the total weight and size of the basket, as well as the distance it has to travel. If the web shop has geographically distributed warehouses, it may be cheaper to ship from a warehouse closer to the customer. However, if the closest warehouse doesn't have all items in stock, there may be a better way to optimize profit. Again, that calculation likely depends on the shipping method chosen by the customer. Thus, a common solution is to select a shipping cost calculation Strategy based on the user's selection. A simplified example may look like this:
public class BasketCostCalculator { private readonly IShippingCostCalculatorFactory shippingFactory; public BasketCostCalculator( IShippingCostCalculatorFactory shippingCostCalculatorFactory) { this.shippingFactory = shippingCostCalculatorFactory; } public int CalculatePrice( ShoppingBasket basket, ShippingMethod shippingMethod) { var shippingCalculator = this.shippingFactory.GetCalculator(shippingMethod); return shippingCalculator.CalculatePrice(basket) + basket.Total; } }
A naïve attempt at an implementation of the IShippingCostCalculatorFactory may involve a switch statement:
public IBasketCalculator GetCalculator(ShippingMethod shippingMethod) { switch (shippingMethod) { case ShippingMethod.Express: return new ExpressShippingCostCalculator(); case ShippingMethod.PriceSaver: return new PriceSaverShippingCostCalculator(); case ShippingMethod.Standard: default: return new StandardShippingCostCalculator(); } }
Now, before you pull Refactoring at me and tell me to replace the enum with a polymorphic type, I must remind you that at the boundaries, applications aren't object-oriented. At some place, close to the application boundary, the application must translate an incoming primitive to a polymorphic type. That's the responsibility of something like the ShippingCostCalculatorFactory.
There are several problems with the above implementation of IShippingCostCalculatorFactory. In the simplified example code, all three implementations of IBasketCalculator have default constructors, but that's not likely to be the case. Recall that calculating shipping cost involves complicated business rules. Not only are those classes likely to need all sorts of configuration data to determine price per weight range, etc. but they might even need to perform lookups against external system - such as getting a qoute from an external carrier. In other words, the ExpressShippingCostCalculator, PriceSaverShippingCostCalculator, and StandardShippingCostCalculator are unlikely to have default constructors.
There are various ways to implement such an Abstract Factory, but none of them may fit perfectly. Another option is to associate metadata with each implementation. Using attributes for such purpose is the classic .NET solution:
public class HandlesShippingMethodAttribute : Attribute { private readonly ShippingMethod shippingMethod; public HandlesShippingMethodAttribute(ShippingMethod shippingMethod) { this.shippingMethod = shippingMethod; } public ShippingMethod ShippingMethod { get { return this.shippingMethod; } } }
You can now adorn each IBasketCalculator implementation with this attribute:
[HandlesShippingMethod(ShippingMethod.Express)] public class ExpressShippingCostCalculator : IBasketCalculator { public int CalculatePrice(ShoppingBasket basket) { /* Perform some complicated price calculation based on the * basket argument here. */ return 1337; } }
Obviously, the other IBasketCalculator implementations get a similar attribute, only with a different ShippingMethod value. This effectively provides a hint about the role of each IBasketCalculator implementation. Not only is the ExpressShippingCostCalculator a basket calculator; it specifically handles the Express shipping method.
You can now implement IShippingCostCalculatorFactory using these Role Hints:
public class ShippingCostCalculatorFactory : IShippingCostCalculatorFactory { private readonly IEnumerable<IBasketCalculator> candidates; public ShippingCostCalculatorFactory( IEnumerable<IBasketCalculator> candidates) { this.candidates = candidates; } public IBasketCalculator GetCalculator(ShippingMethod shippingMethod) { return (from c in this.candidates let handledMethod = c .GetType() .GetCustomAttributes<HandlesShippingMethodAttribute>() .SingleOrDefault() where handledMethod != null && handledMethod.ShippingMethod == shippingMethod select c).Single(); } }
This implementation is created with a sequence of IBasketCalculator candidates and then selects the matching candidate upon each GetCalculator method call. (Notice that I decided that candidates was a better Role Hint than e.g. calculators.) To find a match, the method looks through the candidates and examines each candidate's [HandlesShippingMethod] attribute.
You may think that this is horribly inefficient because it virtually guarantees that the majority of the injected candidates are never going to be used in this method call, but that's not a concern.
The use of attributes has been a long-standing design principle in .NET, but seems to me to offer a poor combination of tight coupling and Primitive Obsession. To be fair, it looks like even in the BCL, the more modern APIs are less based on attributes, and more based on other alternatives. In other posts in this series on Role Hints I'll describe other ways to match objects, but even when working with metadata there are other alternatives.
One alternative is to decouple the metadata from the type itself. There's no particular reason the metadata should be compiled into each type (and sometimes, if you don't own the type in question, you may not be able to do this). Instead, you can define the metadata in a simple map. Remember, 'metadata' simply means 'data about data'.
public class ShippingCostCalculatorFactory : IShippingCostCalculatorFactory { private readonly IDictionary<ShippingMethod, IBasketCalculator> map; public ShippingCostCalculatorFactory( IDictionary<ShippingMethod, IBasketCalculator> map) { this.map = map; } public IBasketCalculator GetCalculator(ShippingMethod shippingMethod) { return this.map[shippingMethod]; } }
That's a much simpler implementation than before, and only requires that you supply the appropriately populated dictionary in the application's Composition Root.
Metadata, such as attributes, can be used to indicate the role played by an object. This is particularly useful when you have to select among several candidates that all have the same type. However, while the Design Guidelines for Developing Class Libraries still seems to favor the use of attributes for metadata, this isn't the most modern approach. One of the problems is that it is likely to tightly couple the resulting code. In the above example, the ShippingMethod enum is a pure boundary concern. It may be defined in the UI layer (or module) of the application, while you might prefer the shipping cost calculators to be implemented in the Domain Model (since they contain complicated business logic). However, using the ShippingMethod enum in an attribute and placing that attribute on each implementation couples the Domain Model to the user interface.
One remedy for the problem of tight coupling is to express the selected shipping method as a more general type, such as a string or integer. Another is to use detached metadata, as in the second example.
Comments
Bottom line: I've landed on just using the container directly inside of these factories. I am completely on board with the idea of a single call to Resolve() on the container, but this is one case where I have decided it's "easier" to consciously violate that principle. I feel like it's a bit more explicit--developers at least know to look in the registration code to figure out which implementation will be returned. Using a map just creates one more layer that essentially accomplishes the same thing.
A switch statement is even better and more explicit (as an aside, I don't know why the switch statement gets such a bad rap). But as you noted, a switch statement won't work if the calculator itself has dependencies that need resolution. In the past, I have actually injected the needed dependencies into the factory, and supplied them to the implementations via new().
Anyway, I'm enjoying this series and getting some nice insights from it.
So an attribute on the implementation class can serve two important purposes here -- first, it does indeed make the intended role of the class explicit, and second, it can give your IoC container registration hints, particularly helpful when using assembly scanning / convention-based registrations.
The detached metadata "injecting mapping dictionary from composition root" sample is great!
In my practice I did such mapping-thing with inharitance and the result is a lot of factories all-over the code, that knows about DI-container (because of lazy-initialization with many dependencies inside each factory)
With some modifications, like generic-parameters and lazy-initialization, injection dictionary over constructor inside such universal one-universal-factory-class really could be great solution for the most cases.

Does this concept look familiar to anyone?
variables [preorder α] [preorder β] (m : α → β) class directed_map : Prop := (mono : monotone m) (dir : ∀ x, directed_on (≥) {a | x ≤ m a})
Turns out this is what you need to map a preorder filter. It's a category
By the way, does anyone have any naming suggestions for preorder filters vs set filters?
"prefilter" just occurred to me
What is a preorder filter?
It is a subset of a preorder which is nonempty, upward closed, and has an element below any two elements in the filter (downward directed)
basically you generalize the part about filters being sets of sets to sets in a more general ordered structure
It looks similar to (and implies) the notion of (co)final functor, but I don't remember seeing this exact notion before.
I like the name "directed map", because you have the property: \a
is directed if and only if the unique map \a \to unit
is directed
"prefilter" however strikes me as a word which should mean a filter minus some property, or something like a filter basis. Compare presheaf/sheaf, (historically) prescheme/scheme = (scheme/separated scheme).
I suppose using filter
for both cases is infeasible, or you wouldn't be asking the question?
filter
and set_filter
? Or is renaming the current one out of the question?
order_filter
and filter
?
We could also make use of namespacing perhaps

Mass Spectrometry Facility / Service
Our Experience
A Regional Mass Spectrometry Facility was established in late 1983 in the Chemistry Department at the University of California Riverside. From its start in 1983, it has been available to any researcher with the need for mass spectrometry analyses. In addition to providing these analyses for our on campus researchers, during our 30 years of existence we have helped over 560 faculty or private firm professionals from over 180 institutions outside of UCR with their mass spectrometry needs. Users have come to us from 40 states, 6 foreign countries, and have included 5 Nobel Laureates. We have analyzed a wide variety of chemical species which up to now have included 49 elements from the preiodic table. Combined, our staff currently has nearly 60 years experience analyzing samples from a variety of sources. We continue to encourage all researchers to take advantage of our considerable experience when they consider their needs for MS analyses.
Our philosophy has always been to work closely with users in order to determine the best approach that will most quickly perform the analyses. When one technique does not seem to confirm an expected MW, we automatically try others to confirm or to provide information about the unexpected species.
Three of our current four instruments have the ability to obtain accurate mass data from which we can provide molecular formula information. The remaining instrument provides MS/MS data in lieu of exact mass measurements.
Since 1988, the mass spectrometry laboratory has been a part of the Analytical Chemistry Instrumentation Facility (ACIF) within the Chemistry Department. Analytical capabilities encompassed include NMR, Optical Spectroscopy, and X-Ray Crystallography.
Please check for the latest status of what is happening at the facility at the Lab Updates page.


Brian O'Driscoll's noticed a promising evolution from Munster
by Raf DialloMunster made a winning start to the Heineken Champions Cup and their evolution has intrigued Brian O'Driscoll.
Johann van Graan's side beat Ospreys 32-13 to earn a bonus point on the road.
Over the summer, Munster also strengthened their coaching setup, including with senior coach Stephen Larkham.
Ireland legend Brian O'Driscoll joined us on Off The Ball to review the weekend's action and also shared his view on Munster's performance and evolution.
"I kind of liked Munster," he said.
Great Combination
"Munster - in this tournament with the way they have appeared to evolve as well and brought in a new coaching ticket that are very respected coaches in [Graham] Rowntree and Larkham, have a wealth of experience at the highest level - I just thought it's potentially a great combination.
"And I think they've come on no doubt from last year - and they've still been getting to consecutive semi-finals.
"I don't think they're the finished article yet. But I've definitely seen an evolution from them and a nasty edge to them that maybe was lacking in the last few years."
He homed in on two sides to Munster's game against Ospreys to highlight the evolution.
"They had a real ferocity to the way they were hitting rucks and counter-rucking. I think after 45 minutes, I heard Sam Warburton say that it was 10 offloads to zero. So they're evolving their game. They're pushing the pass a little bit more - a little bit like Leinster of a couple of seasons ago. That can only come from what happens at training throughout the week.
"So clearly they're practicing and working on their multi-phase and realising that's the way the game is going how they need to evolve with it. I think that's probably Larkham."

I believe the hiring process is broken and needs fixing, so I want to write a series of posts on the subject. Although the articles may deal specifically with the hiring of software people, I believe the content may be relevant to other fields.
Some topics I want to write about:
1. Resumes are redundant.
2. Job adverts are pointless and counterproductive.
3. Years of experience is overrated.
4. People should screen candidates - just not HR.
5. What exactly is the point of the interview?
And perhaps more.
Soon...

You are asked to perform a security audit in a baking company. Their products are represented by Bakery
class and its different subclasses like Cake
and LemonTart
. All the pastries are sold in nice boxes. Prior to being released to the customer, all boxes are checked with carefully designed NaiveQualityControl
class. However, recently a number of mistakes happened and unedible things were packed in boxes and escaped the quality check.
A short look at NaiveQualityControl
led you to the conclusion that it's quite easy to provide NaiveQualityControl
with Box
filled with Paper
that will pass QC. Now your task is to demonstrate this mistake. Here's the code:
/* This class and its subclasses should pass quality check */
class Bakery {}
class Cake extends Bakery {}
/* This one should not */
class Paper {}
/* These boxes are used to pack stuff */
class Box<T> {
void put(T item) { /* implementation omitted */ }
T get() { /* implementation omitted */ }
}
/* This quality checker ensures that boxes for sale contain Bakery and anything else */
class NaiveQualityControl {
public static boolean check(List<Box<? extends Bakery>> boxes) {
/* Method signature guarantees that all illegal
calls will produce compile-time error... or not? */
return true;
}
}
You need to add implementation to Violator.defraud()
method that will do the following:
List of Boxes<? extends Bakery>
according to the method signaturePaper
object in at least one Box
in the listNaiveQualityControl
checkDo not change the method signature or code of any other classes, just add implementation to defraud method.

Time complexity: O(1)Atomically return and remove the last (tail) element of the srckey list,and push the element as the first (head) element of the dstkey list. Forexample if the source list contains the elements "a","b","c" and thedestination list contains the elements "foo","bar" after an RPOPLPUSH commandthe content of the two lists will be "a","b" and "c","foo","bar".
If the key does not exist or the list is already empty the specialvalue 'nil' is returned. If the srckey and dstkey are the same theoperation is equivalent to removing the last element from the list and pusingit as first element of the list, so it's a "list rotation" command.
Redis lists are often used as queues in order to exchange messages betweendifferent programs. A program can add a message performing an LPUSH operationagainst a Redis list (we call this program a Producer), while another program(that we call Consumer) can process the messages performing an RPOP commandin order to start reading the messages from the oldest.
Unfortunately if a Consumer crashes just after an RPOP operation the messagegets lost. RPOPLPUSH solves this problem since the returned message isadded to another "backup" list. The Consumer can later remove the messagefrom the backup list using the LREM command when the message was correctlyprocessed.
Another process, called Helper, can monitor the "backup" list to check fortimed out entries to repush against the main queue.
Using RPOPPUSH with the same source and destination key a process canvisit all the elements of an N-elements List in O(N) without to transferthe full list from the server to the client in a single LRANGE operation.Note that a process can traverse the list even while other processesare actively RPUSHing against the list, and still no element will be skipped.

The native libraries for all supported platforms are provided as JAR files which you can simply reference in your classpath. usb4java automatically determines on startup which libraries are needed for the current platform and extracts them to a temporary directory and loads them from there. This makes it easy to use usb4java because you just need to put the JARs into your classpath. No need to fiddle around with java.library.path or environment variables like LD_LIBRARY_PATH or DYLD_LIBRARY_PATH.
usb4java only extracts the files into a temporary directory when they are inside a JAR file. So if you prefer direct loading without extracting to a temporary directory then you may want to distribute the files in extracted form. Just make sure your classpath includes the directory where you have extracted the JARs. Here is an example application layout for this scenario:
natives/ org/usb4java/ linux-x86-64/libusb4java.so win32-x86-64/libusb4java.dll darwin-x86-64/libusb4java.dylib lib/ usb4java.jar commons-lang3.jar myapp.jar myapp.sh
To make this work just make sure to put the natives folder into your classpath.
When you use usb4java on a platform which is not directly supported by usb4java then you might get one of the following two exceptions:
Native library not found in classpath: /org/usb4java/freebsd-x86/libusb4java.so
Unable to determine the shared library file extension for operating system 'strangeos'. Please specify Java parameter -Dusb4java.libext.strangeos=<FILE-EXTENSION>
If you get the second one then this simply means that your operating system is completely unknown to the usb4java authors and usb4java does not know the file extension of shared libraries on this platform. You can fix this by specifying a Java parameter like this (As explained in the exception):
-Dusb4java.libext.strangeos=so
After this you will most likely get the other exception, which means that there is no native JNI wrapper present for this platform. Your only chance here is to compile this wrapper yourself. I can't predict how this works on really strange platforms but chances are high that your platform is somewhat Unix-compatible. So try this:
1. Install a Java JDK (OpenJDK for example). Make sure the environment variable JAVA_HOME is pointing to the directory where you have installed the JDK.
2. Install the libusb development files.
3. Install Git.
4. Clone the libusb4java source code repository with Git:
$ git clone git://github.com/usb4java/libusb4java.git
5. Enter the cloned libusb4java directory:
$ cd libusb4java
6. Create a build output directory and enter it:
$ mkdir build $ cd build
7. Compile the native library:
$ cmake .. -DCMAKE_INSTALL_PREFIX="" $ make install/strip DESTDIR=/tmp
8. When compilation was successful then the native library can be found in the directory /tmp/lib. The file name depends on your operating system. Make sure you rename it to libusb4java.so (Or whatever file extension your platform uses) and copy this file into the directory /org/usb4java/OS-ARCH/ in your classpath where OS is the name of your operating system and ARCH is your CPU architecture (Both must match the names mentioned in the exception thrown by usb4java.)
If you can't use the GNU compiler or cmake then you are on your own. If you have some experience with compiling JNI libraries then I guess this won't be hard for you. There are only a couple of source files in the src sub folder. You could write a new simple Makefile or whatever is needed on your platform.
If you have problems then please consult the usb4java mailing list (Google group). You can subscribe to it via email by sending a mail to usb4java+subscribe@googlegroups.com.


HTML Introduction
What is HTML?
HTML is the standard markup language for creating Web pages.
- HTML stands for Hyper Text Markup Language
- HTML describes the structure of Web pages using markup
- HTML elements are the building blocks of HTML pages
- HTML elements are represented by tags
- HTML tags label pieces of content such as "heading", "paragraph", "table", and so on
- Browsers do not display the HTML tags, but use them to render the content of the page
HTML Tags
HTML tags are element names surrounded by angle brackets:
<tagname>content goes here...</tagname>
- HTML tags normally come in pairs like <p> and </p>
- The first tag in a pair is the start tag, the second tag is the end tag
- The end tag is written like the start tag, but with a forward slash
inserted before the tag name
Tip: The start tag is also called the opening tag, and the end tag the
closing tag.
The <!DOCTYPE> Declaration
The declaration represents the document type, and helps browsers to display web pages correctly.
It must only appear once, at the top of the page (before any HTML tags).
The declaration is not case sensitive.

6 February 2007
The Egyptian Ministry of Health and Population has announced a new human case of avian influenza A(H5N1) virus infection. The case was confirmed by the Egyptian Central Public Health Laboratory and by the US Naval Medical Research Unit No.3 (NAMRU-3).
The 17-year-old female from Fayyoum Governorate developed symptoms on 25 January 2007 and was initially treated for seasonal influenza. She was hospitalized on 1 February with fever and breathing difficulties, and died on 2 February. Initial investigations into the source of her exposure indicate the presence of sick and dead poultry at her home in the days prior to the onset of symptoms.
Of the 20 cases confirmed to date in Egypt, 12 have been fatal.


Note: This document is a description and a working reference
for the Newsfilter project aimed at creating a public, open-source service
for quality-based filtering and recommendation
of Usenet articles. For more information please review
newsfilter group discussion archives
and references at the end of this document.
Please contact
Sasha Chislenko
with any suggestions or criticisms.
Project Goal
The project is intended to create a technical framework for collaborative
document filtering and recommendations, an information infrastructure, and a
basic set of services allowing to use people's assessments of online documents
for improved navigation, and apply them to Usenet messages.
Approach and aspirations
The project aims to create a set of open standards for storage and
transmission of semantic encodings and client user interfaces,
and the first implementations of crucial architectural components.
This will create an easy-to-use infrastructure that should allow
further rapid development of the system and smooth integration
of additional services.
So far, Net tools concentrated on information storage, transmission,
and representation functions, while all semantic analysis has been
done by humans. Now, we can build another level of standards for
representing, processing, and targeting documents based on their semantic
encoding, and elevate the Web to a new level. In the resulting
environment, the development of intelligent agents and symbolic
AI may become as profitable for third-party services as text
retrieval became with the invention of simple document-storage
systems.
Project structure and deliverables
The project aims to provide design and deliver the first implementations of:
- Formats and storage facilities for rating profiles and other user data
- Data request functions
- Collaborative mechanisms for combining multiple sources of ratings into
a recommendation/filtering stream.
- Client interface
- Algorithms for generating, matching and aggregating ratings profiles
- Algorithms and interfaces for intercommunication of distributed
recommendation and prediction services.
- Help files, online documentation, and readable published code
General scheme and information flows
In the traditional system, the user exchanges
content with the content repository, querying it
to obtain relevant documents. The content search
engine knows nothing about the user. Client interface
stores some simple user settings and allows browsing
and querieng of the content repository and posting of
user messages.
The ratings-enriched system introduces additional
elements: user's own ratings profile, general ratings
repository, and recommendation service.
The right (ratings) wing of the following diagram of
the ratings-based system is very similar to the left
(content) wing, except that the advice it gives
are based on the user-expressed semantics of the
documents rather than their content.

User [+ user profile]
An important concept in the proposed architecture is one
of an
advisor. An advisor is a human or
machine generator of message ratings that the user
decides to rely upon. A user can have multiple advisors
whose recommendations may be combined. Each advisor
has a named area of expertise and a reputation weight
relating the relative utility of their recommendations
to this user.
Every user can be an advisor if he
1) enters ratings
and
2) has anybody who is willing to follow his opinions.
The advisors can be also automatic (kill file or imported
spam filter) or synthetic (e.g., an average of all human
advisors is the "community" advisor, and can have a name
like "comp.ai.alife.human_community")
The aggregation of advisor ratings (in a given named "sense",
area, e.g. "humor" ) is relatively simple, except for the confidence
calculation.
Suppose that :
- Wt(A) is Advisor Weight designated by the user;
- Rating(A,M) is advisor A's rating for message M;
- Conf(A,M) is advisor A's confidence for message M.
Then the aggregated rating can be computed as an average rating by
all advisors, taking weights and confidences into account:
Sum [ Wt(A) * Rating(A,M) * Conf(A,M) ]
R(I)= ---------------------------------------
Sum [ Wt(A) * Conf(A,M) ]
Confidence computation is more complex, and depends on all
advosor confidences, weights, number of advisors that suggested
their ratings, and diversity/deviation of their opinions.
The exact formulas can be selected based on statistical
analysis of the recommendations, to optimize the recommendation
quality (the accuracy of predicting user's ratings).
Basic operations of the service
The system should allow the following operations:
- Selecting the advisor set
The user can directly list good advisors and their
weights, or request N most reputable advisors [in
a given area], or ask for advisors of his friends,
or ask the recommendation service to find appropriate
advisors based on analysis of profiles and reputations,
or a combination of these.
- Getting a general recommendation
The user sends the advisor set [and an area of interest]
to the recommendation service. The service retrieves
ratings of the advisors, aggregates them, and returns
a selected set of messages that according to the opinion
of these advisors (or worst, or most/least popular, or
most controversial) This function can be also
performed on the client if it stores the advisor profiles.
Then the selected messages are fetched from the content
repository.
- Getting a restricted recommendation
The user sends a query to the search engine and gets
a reply with a list of messages and indicators of their
relevance. This list is then passed through the advisor
set, and for each message the recommendation system suggests
its expected quality, with confidence factors.
Then, the messages get resorted based on all indicators of
relevance, quality and confidence.
(This allows taking into account personalized quality
expectation every time search is conducted)
- Improved navigation
Before presenting the user with a list of messages
corresponding to a given newsgroup or a search list, client
software should consult the recommendation service, and
reorder the list, putting definitely good messages on the top
of the list, definitely bad messages on the bottom, and
everything else in between.
- Rating feedback
The user should be able to enter feedback to each reviewed
message. The feedback may include a named rating for the
message, a confidence factor, and a free-form comment.
The user may also request to see who recommended this message,
and adjust the reputation factors for the those advisors.
This function can also be performed automatically.
Data structures
The "semantic data" should represent features of users, advisors,
and messages, as well as their relations.
Data will be kept in standard records (database or XML) allow
easy extensions.
Sample data formats
The two basic types of data records are object description
records and relation (rating) description records.
Object [User/advisor/message] description record
An object profile consists of multiple object records,
describing various features of users, advisors, and messages,
such as name, age, preferred language, URNs, etc.
Each record has the following structure:
- Object Id
- Field name
- Field value
- Time Stamp
- [possibly, Expiration time]
Relation record
Relation records allow to store user and advisor ratings as well
as advisor records.
- Object1 Id User or advisor Id
- Object2 Id Advisor or message Id
- Relation type "Advisor", or "rated message"
- Relation name area of expertise, or message feature, e.g. "funny"
- Relation value Reputation/weight/rating
- Value Confidence
- Time Stamp
- [Free-form comment]
- [possibly, Expiration time]
The confidence reflects the degree to which the source is confident
that the relation value is correct. The confidence may be stronger
if the record was derived from combining a large number of opinions
of reliable agents that agreed on this value (low std.dev), and lower
if there were only a few not very reliable agents that deviated from
each other, or was derived implicitly, etc.
The reason for storing confidence explicitly is that different users
have different degrees of tolerance to false positive and false negative
recommendations.
Also, people sometimes can be interested in messages with low confidence
as these indicate controversial or under-researched objects.
Data repositories
The data records may be stored in databases that may serve
records on request, or published as standard formatted files.
Data requests and transports
Data transport mechanism transfers semantic data, content, and
requests between data repositories, knowledge servers, and user
client software.
The transport can be HTTP, remote database interface, postings on
a designated newsgroup (i.e., alt.newsgroups.ratings), or email.
Each of these mechanisms has its own advantages in terms of
delivery speed, privacy and efficiency. We will start with
the Web interface that appears more immediately useful and
easy to implement.
Data request examples
- Get/write object description records
- get a list of unrated messages among {message list}.
- get a list of most popular messages among {user set}
(combination of number of ratings and average rating)
We also need to specify formats of requests to the data depository.
As we agreed in principle on the structures of requests and
data record formats, the request formats seem to be a matter of
protocol rather than architecture, so I'll skip them here,
except for the opinion that they should also be human-readable,
at least in one of representations.
The communication standard should also allow transparent extensions:
if the services on two sides of the interface can use various extensions
or subsets of the protocol, they should just get whatever parts of the
record are available and process what they can understand.
We need to specify the exact transport syntax of the above records,
as well as field lengths, and then, basically, we'll have the needed
interface - at least for the architectural purposes.
Client Software
Client software should improve the users' navigation in the
document space. It should allow the user to annotate existing
documents (or will annotate them automatically, based on the user's
reading pattern), communicate annotations to data repositories,
and request recommendation from knowledge servers. The
recommendations will be used to filter and reorder the documents.
Algorithms
The semantic services (recommendation servers, reputation brokers, etc. -
need a better generic name!)
aggregate data from multiple users and software agents (this data is
received from the data repositories described above) and form
recommendations that should be used by the client software to
improve selection and presentation of information to the user.
It is also possible to transmit a generic set of data and then perform
the last personalization round on the client, such as weigh recommendations
according to this user's affinity to the recommenders. This allows to
preserve privacy of user data, reduces message traffic, and shifts part
of the computational load to the client.
Requests to semantic servers may include
- Predict ratings for a given message by user X
(e.g., "funny: 0.6, confidence: 0.7; intelligent: 0.1, confidence: 0.9")
- Filter a given list of messages for a user X with given thresholds
- Get a set of "like-minded users"/advisors for user X [for criterion C]
- Sort a given list of messages by predicted rating/confidence combination
- get a list of most controversial messages among user set {X}
(combination of number of ratings, their standard deviation and confidence)
- Get a list of messages that a given set of users considers similar to message I
- Compute reputation of an advisor X (utility of their advice) among user set {Y}
Some of these functions can be iterative.
For example, at the beginning of session a user can request a list of
like-minded users, and then use this list repeatedly to filter search
results or listings for different groups. The user feedback will be
used to adjust the similarity/reputation factors for the selected advisors.
The results of these functions should have the same structure as object and
relation records.
First stage of the project
The first stage of development should create a collaborative
message filtering framework and a basic functional service
utilizing it.
This framework service should include:
- User registration facility (URF)
A user should be assigned, minimally, a unique Id and a password.
The registration can also include a questionnaire.
URF includes client and server sides. Client side is an HTML-form,
server side is a database and a CGI-script.

They will also be given names (e.g. "picture" filter that leaves only pictures).
A conversion utility should turn spam filter's message lists and results of kill files
application to rating value (e.g., name="picture"; rating="0.1"; confidence ="0.85")
- Interface functions allowing users to manually select, exchange,
and merge advisor sets.
- Facility for expressing message selection criteria for a user.
The selection criteria should include the maximal number of messages
a user wants to see in each area of interest, and threshold values
for message quality and aggregated advisor confidence.
- A mechanism for aggregating rating streams from several advisors
into a collaborative recommendation filter.
- A web-based news browsing facility that displays messages
based on this filter and collects message ratings from the user
that will be used in the system.
- Storage and retrieval facilities for messages.
Every message has:
- Id
- Poster
- Date
- Size
- Body
- [optionally, other fields, like keywords]
- Storage and retrieval facilities for user profiles and ratings.
(the stucture of user profile and rating records is listed above)
- Sample utilities converting widely accepted message filters
(keyword search, spam filters, kill files) into rating streams.
- Online documentation, including description of the project goals,
list of contributors, current status, online help, to-do list, and
readable published code.
- A minimal facility for user feedback (at least, email or a guestbook)
- The project should be beta-tested by a limited group of people and
their suggestions should be taken into account in the document describing
further development plans.
The first stage of development should result in the creation of
a basic, immediately useful service in a short time frame (counting
on 2 developers * 3 months of work) that will be scaleable and will
allow multiple extensions.
The extensions, to be developed and/or integrated into the service during
the following stages of the project, should include complex message evaluation
schemes, automated selection of advisors for a given person, complex content
search utilities in addition to browsing, additional sources of
information, etc. There selection for the next stages of the project
will be determined during the implementation of the first stage, and
depending on its results and people's feedback.
Interface specification for stage 1
Page 1: Welcome screen.
A short text describing the service and latest announcement.
links to:
- new user registration
- existing user login
(the above may be combined)
- online documentation
Page 2. New user registration
Minimally:
- name (should be unique)
- password (some simple restriction, like at least 4 letters)
Possibly more - a simple questionnaire:
Age, gender, education level,
a few keywords describing interests,
"want to be on update mailing list"?
Page 3: User login
Could be the same as registration.
Name, Password. Cookies if we manage.
Login should give us User Id and profile.
Page 4. Configuration screen
(people get here from login)
- newsgroup selector (User's usual newsgroup set, plus ability to add)
- topic selector (user's usual interests, plus ability to add from other
topics mentioned in this newsgroup)
- advisor selector
The user sees a list of his usual advisors [relevant to these topics and newsgroup(s)]
and also a list of community advisors that he can add to his own list.
The advisor selector record looks like:
<advisor name>
<checkmark> - check to include, uncheck to exclude
<rating name>
<reputation value> - [0 to 1] Userís assigned reputation, or community reputation.
E.g.:
<Andrei><x> <general><0.7>
<Sasha> <x> <science> <0.6>
<Sasha> <-> <Culture> <0.4> (community-suggested value)
The checked fields represent userís advisors; the rest are taken from the most
reputable advisors in the group, for userís consideration, and may be included.
All selections should be stored in user profile for later use, so that the user doesn't
have to re-specify them every time.
- Selection conditions: minimal rating, minimal total confidence for each message
to be displayed.
- Search button. When this button is pressed server searches for all
messages that satisfy selected news groups and advisors, browsing page is loaded.
Links to browsing and documentation pages.
Page 5. Browsing page
Four horizontal areas, from top down:
-
Topmost line: newsgroup/topic selector
fields (editable):
- Name of browsing newsgroup (e.g. "misc.philosophy")
- Name of interest (e.g. "religion")
- Top frame (under the top line): message title (scrollable)
Contains normal message title fields: poster, date, size[?], subject,
and also predicted quality (averaged rating and confidence).
(Maybe, also - top advisors?)
Sortable by any field - or at least, by date and rating.
The frame should have adjustable lower bound. Default height: 30%.
- Bottom frame: Message body (scrollable)
The message whose title was selected from the top frame.
- Bottom line: Feedback fields.
- Interest (default: browsing interest from the top field)
- rating value;
- confidence factor (with default value, to be stored in user profile)
- "Reply" button - calls a new screen for writing a reply
with parameters taken from the message.
- Links to: configuration page, main page.
- Documentation screens:
- Project description - why is it necessary, how it is useful, etc.
- Help (how to use it)
- FAQ
- to do list (known problems and planned changes)
- feedback form - user feedback goes to developer list and/or
guestbook.
- code to download
(one Zip file with all HTML pages, scripts, and installation
instructions)
More general notes on communications between parts of the service
In the mature service (beyond the first stage) we will have the following agents
producing and consuming ratings data:
- rating agency.
This is an agent that takes a single message and produces a rating
record (e.g., human; killfile; word search; any other message
analysis mechanism). Also known as advisor or expert.
- rating repository (profile server)
Stores and serves profiles (groups of rating records) on request
- recommendation server
Analyses profiles, matches users and advisors, aggregates ratings
values for different profiles, produces composite indicators of
quality, popularity, controversialness, etc. of messages. Also,
it should use statistical analysis to optimize its algorithms
for various metrics of service quality.
This is the most complex part of the ratings processing mechanism,
and the one that will be barely present in the first stage (except,
mostly, for merging advisor profiles)
- User Client
(somewhat overlaps with rating agency where a human user is concerned;
the emphasis here is on consumption, rather than production, of ratings)
Issues requests for retrieval of most appropriate advisors and messages
in given categories.
Each of these agencies may be viewed as an Interactive Agent that can
exchange requests with others. The request types may partially overlap
between these agents. I can suggest the following types of communications
(no claim about completeness of this list):
- 1. Requests [typically] directed at the record server:
- profile data query (directed at the profiles/ratings database)
For descriptive (non-rating) part of user profile, the query
may specify a UserId, and receive user data, or specify a condition
on user data, and receive a set of qualifying records.
For ratings part, the query can specify any condition on
rater Id, User Id, rating name, value, confidence, and time,
and receive matching ratings records.
For example, a query may request all ratings by the given set of
advisors for a selected message.
We can also have pending queries, with an expiration time, for agents
who want to be notified when new data appears that matches their request.
- Data storage request.
Sends an attribute or rating record for storage
(typically, this can be sent by a rater or recommendation server
to a rating server)
Receives a confirmation.
- Data removal request.
Sends a condition on the data to be removed, and authorization.
Receives a confirmation.
- 2. Requests to the recommendation/computation server
- 2a. Simple requests
- profile merger request
sends a set of rating profiles; receives a single profile
with combined ratings and confidence factors.
The simplest case here is that for computation of a predicted
message rating by a set of advisors.
- ?
- 2b. Complex requests (trigger a series of consecutive operations)
- advisor set [re]computation
sends a user profile, existing advisor set, relation name, and number of
advisors required.
Updates advisor set with the advisors taken from the existing advisors'
lists, most reputable community advisors, advisors with highest
affinity to the user, etc., and returns a combined set with optimized
weights.
- prediction request:
Starts with a user Id, an message Id, and rating relation name.
Gets a list of advisors for the user.
If there are any, gets their ratings of the message.
If there are any, merges them.
If either advisors or their ratings for the message are missing,
starts the "fallback method": gets an average rating for the message.
If there are no ratings, returns average rating value with confidence 0.
- message list reordering:
Sends a user Id, a list of message Ids, and rating relation name.
Goes through a series of operations similar to described above;
Returns an ordered message list (by quality, in descending order.
Or by any other factor, if one is interested in controversial,
popular, unknown, etc. messages)
- 2c. Special computation requests:
Calls to special-purpose functions.
For example, consistency check on the database,
calculation of average prediction efficiency,
optimization of algorithm parameters, reclustering
of synthetic profiles, etc.
- 3. Other action requests:
request to perform certain actions, such as publish data,
back up the database, etc.
We can notice that the above communications are all called
requests. In fact, request only originates a [sequence of]
communication(s) listed above.
The sequence of communications usually starts with a request
and goes through action, transfer of stored or computed
data, and completion confirmation. These communication
sequences may loop, chain or extend in time to form dialogs
and other transaction sequences.
We should be able to define transaction syntax after we settle
on Agent Interaction Protocol, Webmind SQL interface, and other
related things.
Of course, we do not expect to implement all of these things
in the first stage of Newsfilter. Hopefully though, this
discussion can help us define the service structure that can
be extended into more complex services and be compatible with
Webmind.

I have been in solo private practice for the past 17 years. It would not be an exaggeration to say that I thoroughly detested the business side of medicine as much as I enjoyed taking care of my patients. Unfortunately, as you could not do one without the other, I did not have much of a choice. The first few years were rocky with a high turnover of office staff, many of whom did not have prior medical office experience. I initially used a billing service but then an attempt to do it in-house was unsuccessful. About 11 years ago, you started doing my billing and that continues until the present time. Thinking back about it, this has been one of the most enduring relationships over my years in practice. Not even once since, do I recall having entertained a change of my billing service. In spite of the disheartening complexity of the system, I always had the comfort of knowing that I had a reliable partner who helped us navigate the rough waters. I have always admired the skill and consistency with which you and your staff handled our billing. Your choice of staff has been excellent and when I visited your office recently, I was impressed by the professional yet collegial atmosphere there. I often regarded your interaction with my own office staff as a stabilizing influence at times of stress. Additionally, I appreciated that the periodic reports you gave me contained the important information without inundating me with useless details. Your advice has been very valuable in many of the business decisions I made. A tribute to your good management is that in spite of the growth of your billing agency, the quality of the service you provide has not declined. I've only received positive feedback from the physicians I referred to you.
In conclusion, I would like to thank you Beth for the many services that you and your agency have provided me with over the years. Your contributions were vital to the success of my practice. I wish you all the best and keep up the good work!

Client from 1997 until retirement
On July 31st 2018 we closed our independent practice of Pediatrics of forty nine years In Reston, VIrginia. The intention of this letter is to recommend ESM Billing & Consulting Inc. Until twenty one years ago we did our billing with several other companies with multiple results, none of which we found satisfactory.
Then in 1997 we found Ms. Beth McClenahan, founder and owner of ESM. Throughout all these years their billing, collection and consulting have been extremely honest, reliable and dependable. Our practice beneffited tremendously with their services.
Very truly yours,

DashCore is a Bootstrap 4.x HTML Template ready to showcase your SaaS, Startup and Software solution. The download includes the complete source files including HTML, CSS, and JavaScript as well as SCSS stylesheets for easy customization.
If you have any questions that are beyond the scope of this help file, please feel free to email us via our user page contact form, or write direct to<EMAIL_ADDRESS>please include your purchase code in order for us to verify you. Thank you so much !!!
The template is organized in the following way:
This template is based on HTML5 boilerplate structure and the latest version of Twitter Bootstrap framework (4.0 Beta). Please visit http://www.getbootstrap.com if you want to learn more about Bootstrap and it components.
The general HTML structure appears in the following format:

This template uses SCSS for stylesheets. For more information about SCSS, visit http://sass-lang.com/guide.
Template SCSS files are located in the /SASS directory. Vendor CSS files are located in the /html/css directory.
We need to compile SCSS files to CSS to make them usable. All compiled files are located in the /css folder.
All SCSS files are separated by component types for easy customization.
There is a main file for the theme style.scss
file which has references to all .scss files that compose the theme.
Those files use Bootstrap variables and mixins in order to compile to CSS.
You can modify those files to include additional style or remove any unwanted reference, one use case could be to leave the variation of a section you like and remove references to the others.
Do not remove references to Bootstrap and FontAwesome components as it will not compile.
@import "bootstrap/scss/functions"; @import "bootstrap/scss/mixins"; @import "bootstrap/scss/variables"; @import "font-awesome/web-fonts-with-css/scss/variables"; @import "angled-edges/angled-edges"; // Import core stuff @import "style/variables"; @import "style/reset"; @import "style/__mixins"; @import "style/__navigation"; @import "style/__forms"; @import "style/__utilities"; // Import styles //@import "style/loader"; @import "style/mockup"; @import "style/icons"; @import "style/__section"; @import "style/__pricing"; @import "style/__heading"; @import "style/custom";
This template uses several JS files. Those files are loaded at the bottom of the page to increase the site speed and rendering.
Some of the javascript files used are:
Please refer to Credits section to see the complete list of js files.
We use some PHP scripts to process the submission of the forms on the template
Every form in the HTML has an action
attribute with the path relative to the PHP file which will process it
<form id="form-contact" action="srv/contact.php" data-response-message-animation="slide-in-up"> ... </form>
By default we left it this way, you can move the files to another location or rename them as you like, if you do that don't forget to update the action
attribute to reflect your changes. Please refer to the
forms section for additional details on the file structure and PHP code
We use MailChimp API 3.0 to connect to the service, our implementation only include
Adding a member to a list,
for this sake we create a class in /srv/integration/MailChimp.php
file.
We implement this class to make the subscription process in subscribe.php
. There you must provide API_KEY and LIST_ID
with your own. We assume you know how to get those values.
define("LIST_ID", "[YOUR LIST ID]"); define("API_KEY", "[YOUR API KEY]");
This is the only change needed to make the script to work.
We explain how easy is to customize the template through HTML, SCSS or JS changes to suit your needs.
We use Google Open Sans and Lato fonts by default.
To change the embedded font, open the HTML page you want and locate the head section and change the font as you wish. Make sure to change the font names in CSS files as well.
<link href="https://fonts.googleapis.com/css?family=Lato:300,400|Open+Sans:300,400,700" rel="stylesheet">
Once you have changed the font, look for $font-family-template
and $font-family-complementary
variable in /SCSS/_variables.scss and adjust properly.
$font-family-template: "Open Sans", $font-family-base; $font-family-complementary: "Lato", "Open Sans", $font-family-template;
This template is ready to use any colors scheme, for wich we use SCSS to create colors pallete and process the CSS dynamically and show your colors right away.
You change your colors scheme in /SCSS/_variables.scss
.
We use 6 main colors for each scheme which can be completely customized to fit your needs.
To include your own colors just change variables to your values and compile.
$color-1: #ffffff !default; $color-2: #646f79 !default; $color-3: #7b68ee !default; $color-4: #028fff !default; $color-5: #143350 !default; $color-6: #f4f8fb !default;
In addition to the image cover background, each section may include an overlay. There are so many colors of overlays as defined in the colors scheme, all named by its index (.overlay-1, .overlay-2, .overlay-3 and so on).
You can choose the level of opacity 10 to 90 by using the alpha-?
css class.
Make sure you have included .overlay
class.

DashCore comes with fully functional form submission. Every form has an action
attribute, this is the script which will process the form in server side. We have set up those scripts in srv
folder.
<form action="srv/subscribe.php" class="form form-subscribe" method="post" data-response-message-animation="slide-in-left"> <input type="text" name="Contact[fullName]"/> ... </form>

One last step!!!
 To complete the subscription process, please click the link in the email we just sent you.

The name of the inputs should be in array format, for example: Contact[fullName]
, this way is easier to read on the server, and bind the values into the corresponding model.
The value inside the squared brackets is the name of the attribute in your model, it is case sensitive.
Each script has references to the core libraries we have developed.
// srv/suscribe.php include('./integration/MailChimp.php'); include('./models/SubscribeModel.php');
// srv/models/SubscribeModel.php namespace models; include __DIR__ . '/../components/Model.php'; use components\Model;
All of these references are located relatively to the scripts. You can change the location of the files or rename them, by doing this you must update the files to reflect your changes.
Note how each file has include
statements, and how the path
is relative to its container, this way PHP knows where to find those references.
Advice response-message-animation="slide-in-left"
in the form
tag.
This attribute indicates the notification message animation should be when a response is available. If the attribute is present you must provide an element with response-message
css class next to the form.
When the response is available the message will replace the form with the animation you indicated. At this time only slide-in-left
animation is available, but you can create your owns. __forms.scss
is where you may want to create the animations for your forms
As long as we improve and extend the template, some topics may need extra explanation in order for you to fully customize them.
We use the button pointed out bellow as a reference to relocate the page header mockups when the page is viewed on mobile devices.
There are several considerations you must attend when customizing this variation
If you would want to remove the .learn-more
button, you will need to add another element, preferable within the same section and/or position as the button was.
This is because this element is used as a reference for relocating the mockups.
The code snippets above shows how the .learn-more
button is used as a reference to reposition the mockups, so if removed the code will break on line 52
If you change the default css class for this button, please be sure to change it on the javascript as well thus the element can be found and avoid any error or misbehavior.
The following resources were used to create this template. We are much obligated to their developers.
Any Images or logos used in previews are not included in this item or final purchase and you need to contact authors to get permission in case you want to use them in your commercial or non-commercial projects.
For some of them we are allowed to make reference, in case you wanted to use them in your design
The SVG icons you saw in the preview were taken from https://flaticon.com, those icons free to download with attribution, we used the ones in the following links.

Axios is rich-feature HTTP client that is widely used in dozens of applications. That's why Nest wraps this package and exposes it by default as a built-in HttpModule
. The HttpModule
exports HttpService
that simply exposes axios-based methods to perform HTTP request, but also, transforms return types into Observables
.
In order to use a HttpService
, we need to import HttpModule
.
@Module({
imports: [HttpModule],
providers: [CatsService],
})
export class CatsModule {}
Hint TheHttpModule
is exposed from@nestjs/common
package.
Then, you can inject HttpService
. This class is easily accessible from @nestjs/common
package.
@Injectable()
export class CatsService {
constructor(private readonly httpService: HttpService) {}
findAll(): Observable<AxiosResponse<Cat[]>> {
return this.httpService.get('http://localhost:3000/cats');
}
}
@Injectable()
@Dependencies(HttpService)
export class CatsService {
constructor(httpService) {
this.httpService = httpService;
}
findAll() {
return this.httpService.get('http://localhost:3000/cats');
}
}
All methods return AxiosResponse
wrapped with Observable
object.
 Read more about them here. To configure underlying library instance, use register()
method of HttpModule
.
@Module({
imports: [
HttpModule.register({
timeout: 5000,
maxRedirects: 5,
}),
],
providers: [CatsService],
})
export class CatsModule {}
All these properties will be passed down to the axios constructor.
