The DynamicProxy project was created to overcome the CLR's proxy (in)capabilities. There are proxies in the CLR world, but they can be considered a bit intrusive as it forces one to extend MarshalByRefObject or ContextBoundObject.
You can use DynamicProxy to generate proxies on the fly for one or more interfaces (supporting concrete classes is on the plans as well)
The lastest version of source can be obtained from Avalon Subversion repository.
The DynamicProxy relies on Reflection.Emit to generate new classes that implements the specified interfaces and delegates to your implementation of IInvocationHandler. The usage is very simple. You only need to invoke ProxyGenerator.CreateProxy specifying the interfaces that will be behind the proxy and your implementation of IInvocationHandler:
using Apache.Avalon.DynamicProxy; public interface IMyInterface { String Name { get; set; } void DoSomething(int x, int y); } public class YourProxyInvocationHandler : IInvocationHandler { public object Invoke(object proxy, MethodInfo method, params object[] arguments) { // do something before object returnVal = method.Invoke( realInstance, arguments ); // do something after... return returnVal; } } object proxy = ProxyGenerator.CreateProxy( typeof(IMyInterface), new YourProxyInvocationHandler( new MyInterfaceImpl() ) ); // proxy can be safely casted to IMyInterface IMyInterface inter = proxy as IMyInterface;
You can also overrides the implementation of StandardInvocationHandler.
public class YourProxyInvocationHandler : StandardInvocationHandler { protected override void PreInvoke(object proxy, MethodInfo method, params object[] arguments) { } protected override void PostInvoke(object proxy, MethodInfo method, ref object returnValue, params object[] arguments) { } }
If you'd like to learn more about proxies in .Net and other similar solutions to generate proxies on the fly, please follow these links:
- Dynamic Proxies in .NET: Discussions and explanation about the possibilities of proxies.
- Java like proxies in .Net: Explanation of the problems which leaded to development of Avalon DynamicProxy.
- Stefan Zobel - for his suggestion of using ldtoken
- SpringFramework.Net guys - for their interest and willingness to help
- AspectSharp project - for sticking with it


This is a timed test. Your goal is to have the most time remaining on the timer as possible. The timer will decrease 15 seconds for every wrong answer you click. Good luck!

| Package | feathers.motion.transitions |
| Class | public class ScreenSlidingStackTransitionManager |
| Inheritance | ScreenSlidingStackTransitionManager Object |
ScreenNavigator
that slides out the old
screen and slides in the new screen at the same time. The slide starts
from the right or left, depending on if the manager determines that the
transition is a push or a pop.
Whether a screen change is supposed to be a push or a pop is
determined automatically. The manager generates an identifier from the
fully-qualified class name of the screen, and if present, the
screenID
defined by IScreen
instances. If the
generated identifier is present on the stack, a screen change is
considered a pop. If the token is not present, it's a push. Screen IDs
should be tailored to this behavior to avoid false positives.
If your navigation structure requires explicit pushing and popping, a custom transition manager is probably better.

public RMIConnector(JMXServiceURL url, Map<String,?> environment)
Constructs an RMIConnector
that will connect
the RMI connector server with the given address.
The address can refer directly to the connector server, using one of the following syntaxes:
service:jmx:rmi://[host[:port]]/stub/encoded-stub service:jmx:iiop://[host[:port]]/ior/encoded-IOR
(Here, the square brackets []
are not part of the
address but indicate that the host and port are optional.)
The address can instead indicate where to find an RMI stub through JNDI, using one of the following syntaxes:
service:jmx:rmi://[host[:port]]/jndi/jndi-name service:jmx:iiop://[host[:port]]/jndi/jndi-name
An implementation may also recognize additional address syntaxes, for example:
service:jmx:iiop://[host[:port]]/stub/encoded-stub
url
- the address of the RMI connector server.environment
- additional attributes specifying how to make
the connection. For JNDI-based addresses, these attributes can
usefully include JNDI attributes recognized by InitialContext
. This
parameter can be null, which is equivalent to an empty Map.IllegalArgumentException
- if url
is null.public RMIConnector(RMIServer rmiServer, Map<String,?> environment)
Constructs an RMIConnector
using the given RMI stub.
rmiServer
- an RMI stub representing the RMI connector server.environment
- additional attributes specifying how to make
the connection. This parameter can be null, which is
equivalent to an empty Map.IllegalArgumentException
- if rmiServer
is null.public String toString()
Returns a string representation of this object. In general,
the toString
method returns a string that
"textually represents" this object. The result should be a
concise but informative representation that is easy for a
person to read.
public JMXServiceURL getAddress()
The address of this connector.

JMXConnector
Establishes the connection to the connector server.
If connect
has already been called successfully
on this object, calling it again has no effect. If, however,
JMXConnector.close()
was called after connect
, the new
connect
will throw an IOException
.
Otherwise, either connect
has never been called
on this object, or it has been called but produced an
exception. Then calling connect
will attempt to
establish a connection to the connector server.
connect

- the properties of the connection. Properties in
this map override properties in the map specified when the
JMXConnector

Artificial intelligence algorithm can learn the laws of quantum mechanics
| Source: | University of Warwick |
| Summary: | Artificial intelligence can be used to predict molecular wave functions and the electronic properties of molecules. This innovative AI method could be used to speed-up the design of drug molecules or new materials. |
Artificial Intelligence can be used to predict molecular wave functions and the electronic properties of molecules. This innovative AI method developed by a team of researchers at the University of Warwick, the Technical University of Berlin and the University of Luxembourg, could be used to speed-up the design of drug molecules or new materials.
Artificial Intelligence and machine learning algorithms are routinely used to predict our purchasing behaviour and to recognise our faces or handwriting. In scientific research, Artificial Intelligence is establishing itself as a crucial tool for scientific discovery.
In Chemistry AI has become instrumental in predicting the outcomes of experiments or simulations of quantum systems. To achieve this, AI needs to be able to systematically incorporate the fundamental laws of physics.
An interdisciplinary team of chemists, physicists, and computer scientists led by the University of Warwick, and including the Technical University of Berlin, and the University of Luxembourg have developed a deep machine learning algorithm that can predict the quantum states of molecules, so-called wave functions, which determine all properties of molecules.
The AI achieves this by learning to solve fundamental equations of quantum mechanics as shown in their paper 'Unifying machine learning and quantum chemistry with a deep neural network for molecular wavefunctions' published in Nature Communications.
Solving these equations in the conventional way requires massive high-performance computing resources (months of computing time) which is typically the bottleneck to the computational design of new purpose-built molecules for medical and industrial applications. The newly developed AI algorithm can supply accurate predictions within seconds on a laptop or mobile phone.
Dr. Reinhard Maurer from the Department of Chemistry at the University of Warwick comments:
"This has been a joint three year effort, which required computer science know-how to develop an artificial intelligence algorithm flexible enough to capture the shape and behaviour of wave functions, but also chemistry and physics know-how to process and represent quantum chemical data in a form that is manageable for the algorithm."
The team have been brought together during an interdisciplinary 3-month fellowship program at IPAM (UCLA) on the subject of machine learning in quantum physics.
Prof Dr Klaus Robert-Muller from the Institute of Software Engineering and Theoretical Computer Science at the Technical University of Berlin adds:
"This interdisciplinary work is an important progress as it shows that, AI methods can efficiently perform the most difficult aspects of quantum molecular simulations. Within the next few years, AI methods will establish themselves as essential part of the discovery process in computational chemistry and molecular physics."
Professor Dr Alexandre Tkatchenko from the Department of Physics and Materials Research at the University of Luxembourg concludes:
"This work enables a new level of compound design where both electronic and structural properties of a molecule can be tuned simultaneously to achieve desired application criteria."

Plugin note
This functionality is contained within an expression evaluator plugin. As such, it is available only when the corresponding plugin is installed.
Plugin assembly
CSF.Zpt.ExpressionEvaluators.PythonExpressions.dll
Plugin class
CSF.Zpt.ExpressionEvaluators.PythonExpressions.PythonExpressionEvaluator
Expression prefix
python:
TALES 'python' expressions
python:
expressions make it possible to include and evaluate TALES expressions written in
the Python programming language in your ZPT-Sharp documents.
The text following the python:
prefix must be a valid python expression,
such that it may be evaluated if it appeared after a Python return
keyword -
assuming that all of the relevant variables are in-scope.
Python internals
Python expressions internally make use of the IronPython framework to parse and evaluate python expressions.
The Python language version supported is dependant upon IronPython's own support. At present, Python version 2.7 is the maximum language version available.
Modules and imports
At present, no modules are imported for python expressions. There is also no mechanism to specify modules to be imported either.
There are planned changes which will permit the importing of modules. These changes are lined up for a future version of this expression evaluator plugin.
Important note on variable names
In the same way as with C♯ expressions, if the python expressions plugin is installed then all TALES variable names must be valid python variable names. Note that the Python expression evaluator is not one of the plugins installed by default for new installations.
Where the python expression evaluator plugin is installed, it does not matter whether the variables are used within a Python expression or not. If an improperly-named variable is in-scope when a python expression is evaluated then the presence of that variable will corrupt the expression.

--- layout: post status: publish published: true title: Grails Embedded Classes ClassCastException author: display_name: Geoff Lane login: admin email<EMAIL_ADDRESS>url: http://www.zorched.net author_login: admin author_email<EMAIL_ADDRESS>author_url: http://www.zorched.net date: '2009-04-21 21:57:50 -0400' date_gmt: '2009-04-22 03:57:50 -0400' categories: - Code - Groovy tags: - groovy - grails - bugs ---
Using ORM tools allow you to map the data to a database independently of how your object model looks. Grails supports one-to-many and one-to-one relationships if you want to have the data in different table. But what about when you want to map a single table to multiple objects? In Grails a has a relationship where all the data is stored in a single table is defined by using the embedded syntax. (This creates a component in the Hibernate mapping world.)
An example of using the embedded syntax to create a compositional relationship: {% highlight groovy %} class Person { static embedded = ['address'] String name int age Address address = new Address() } class Address { String street String street2 String city String state String zip static constraints = { street2(nullable:true) } } {% endhighlight %}
This is all great, but... When you attempt to databind against the Person model including Address properties, you end up with an exception:
2009-04-17 20:36:10,058 [13260127@qtp2-0] ERROR errors.GrailsExceptionResolver - java.lang.ClassCastException: Address$__clinit__closure1 org.codehaus.groovy.runtime.InvokerInvocationException: java.lang.ClassCastException: Address$__clinit__closure1 at org.codehaus.groovy.reflection.CachedMethod.invoke(CachedMethod.java:92) at groovy.lang.MetaMethod.doMethodInvoke(MetaMethod.java:234) at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:1061) at groovy.lang.ExpandoMetaClass.invokeMethod(ExpandoMetaClass.java:910) at groovy.lang.MetaClassImpl.invokeMethod(MetaClassImpl.java:892) at groovy.lang.Closure.call(Closure.java:279) at groovy.lang.Closure.call(Closure.java:274)
It ends up there is a bug in Grails versions 1.0.4, 1.0.5 and 1.1 that is causing this. That bug is related to the constraints on the embedded class, in this case the Address class. Removing the constraints allows the object to be properly databound, with the obvious downside of lacking constraints.
I have filed a bug about this: GRAILS-4446. So hopefully it will be fixed soon. Hopefully if other people are having this problem they will help them out.
Update: There is another workaround which is to declare the embedded class in its own file which makes it a first-class Domain object. When that's done the constraints work as expected. The downside is that this means that a table will be created for the embedded domain class (and never used).


GIRLFIGHT (2000) 3 1/2 stars out of 4. Starring Michelle Rodriguez, Paul Calderon, Santiago Douglas, Ray Santiago and Jaime Tirelli. Written and directed by Karyn Kusama. Rated R
Her eyes burn. They pierce through you like a laser beam through butter.
Her name is Diana Guzman. She's a high-school senior with a chip on her shoulder.
Life has not been kind to Diana.  She lives in the projects of Brooklyn with her father and brother.

But then, Diana decides that boxing is a way to express her anger, her frustration, and she convinces Hector, Tiny's coach, to secretly train her.
This is the simple plot for "Girlfight," an impressive feature film debut by writer-director Karyn Kusama as well as for its star, Michelle Rodriguez.
You may think, ah, a female "Rocky." But, sorry. "Girlfight" does not offer the same uplifting kind of ending as Sylvester Stallone's classic, even though it does end on a positive note.
What "Girlfight" does, is trace the growth - spiritual and physical - of Diana, as she learns to come to terms with herself and the world around her.
For Diana, boxing is a form of self-expression. It is her arena for gathering her self-respect.
Kusama's film is no feminist essay on the inequities of sports. Girlfight is about people, not politics.
As Diana, Rodriguez is lovely and volatile. She is not a classic beauty. Hers is a tough, urban loveliness. Rodriguez, for a newcomer, is able to mix smoldering danger with an appealing vulnerability.
She boxes, not to make a statement, but simply because she likes it. To her, it's a way to be noticed, which she isn't at home.
The most powerful scene in the film comes when Diana confronts her father, Sandro (Paul Calderon), who threatens to beat her.
"Girlfight" also is a love story, as Diana is attracted to Adrian (Santiago Douglas), a fellow boxer. It is one of Kusama's in-jokes that she names this character after Rocky's love interest.
The bittersweet romance that grows between Diana and Adrian is threatened by events in the gym and ring, but the two youths are able to confront their differences.
Like most first-time independent films, "Girlfight" has some rough edges. It is a bit slow in a couple of spots. Yet Kusama's direction and Rodriguez's charisma overcome any flaws.
"Girlfight" is a tough, touching movie, introducing a filmmaker and actress who should have an impact on the industry for years to come.

In tangled wreaths, in clustered gleaming stars,
In floating, curling sprays,
The golden flower comes shining through the woods
These February days;
Forth go all hearts, all hands, from out the town,
To bring her gayly in,
This wild, sweet Princess of far Florida –
The yellow jessamine.
The live–oaks smile to see her lovely face
Peep from the thickets; shy,
She hides behind the leaves her golden buds
Till, bolder grown, on high
She curls a tendril, throws a spray, then flings
Herself aloft in glee,
And, bursting into thousand blossoms, swings
In wreaths from tree to tree.
The dwarf–palmetto on his knees adores
This Princess of the air;
The lone pine–barren broods afar and sighs,
“Ah! come, lest I despair;”
The myrtle–thickets and ill–tempered thorns
Quiver and thrill within,
As through their leaves they feel the dainty touch
Of yellow jessamine.
The garden–roses wonder as they see
The wreaths of golden bloom,
Brought in from the far woods with eager haste
To deck the poorest room,
The rich man’s house, alike; the loaded hands
Give sprays to all they meet,
Till, gay with flowers, the people come and go,
And all the air is sweet.
The Southern land, well weary of its green
Which may not fall nor fade,
Bestirs itself to greet the lovely flower
With leaves of fresher shade;
The pine has tassels, and the orange–trees
Their fragrant work begin:
The spring has come – has come to Florida,
With yellow jessamine.

init() and destroy() Or @Bean(initMethod=”init”,destroyMethod=”destroy”)
Spring event and listeners
Spring Boot Runners
Here is rough idea behind method that will be called.
Bean Initialize
Bean Destroy
Java supported @PostConstruct and @PreDestroy
This is the very simple one, you just need to annotate any method inside you Bean class with these annotations and spring will take care of calling it. @PostConstruct is called once bean is intialized an ready for use. @PreDestroy is called once conatiner tries to remove the bean.
Implement BeanPostProcessor
BeanPostProcessor is spring interfaces which allows you to write your own implementations of org.springframework.beans.factory.config.BeanPostProcessor.BeanPostProcessor, there can be n number of BeanPostProcessor in your application and the org.springframework.core.Orderedorder is defined by getOrder method from Ordered interface.
Multiple different interfaces and overriding there methods.
There are many different interface *Aware interfaces and two InitializingBean DisposableBean interfaces. They provide some methods which has special role spring. Each Aware interface are called after some specific events. We will not discuss this in details since there are many. It can be covered in another topic.
init() and destroy() Or @Bean(initMethod=”init”,destroyMethod=”destroy”)
init() and destroy()are part of Spring XML based configuration and @Bean(initMethod=”init”,destroyMethod=”destroy”)are part of Spring annotation based configuration, but they both do the same thing. Here is how to use them.
XML Based.
Spring event and Listeners
Spring emits many application events and you register listeners to them, to do that you just need implement ApplicationListener specific type of event such as below example. Here once ContextRefreshedEvent is raised by spring this listener will be called and intern it will call contextInit method of MyBean.
Spring Boot Runners
Spring comes with two Runner interfaces CommandLineRunner and ApplicationRunner and they are called after application is initialized. Here is an example.


5.6. The Arrow OperatorThe arrow operator (->) provides a synonym for expressions involving the dot and dereference operators. The dot operator (Section 1.5.2, p. 25) fetches an element from an object of class type: item1.same_isbn(item2); // run the same_isbn member of item1 If we had a pointer (or iterator) to a Sales_item, we would have to dereference the pointer (or iterator) before applying the dot operator: Sales_item *sp = &item1; (*sp).same_isbn(item2); // run same_isbn on object to which sp points Here we dereference sp to get the underlying Sales_item. Then we use the dot operator to run same_isbn on that object. We must parenthesize the dereference because dereference has a lower precedence than dot. If we omit the parentheses, this code means something quite different: // run the same_isbn member of sp then dereference the result! *sp.same_isbn(item2); // error: sp has no member named same_isbn This expression attempts to fetch the same_isbn member of the object sp. It is equivalent to *(sp.same_isbn(item2)); // equivalent to *sp.same_isbn(item2); However, sp is a pointer, which has no members; this code will not compile. Because it is easy to forget the parentheses and because this kind of code is a common usage, the language defines the arrow operator as a synonym for a dereference followed by the dot operator. Given a pointer (or iterator) to an object of class type, the following expressions are equivalent: (*p).foo; // dereference p to get an object and fetch its member named foo p->foo; // equivalent way to fetch the foo from the object to which p points More concretely, we can rewrite the call to same_isbn as sp->same_isbn(item2); // equivalent to (*sp).same_isbn(item2) |

Strongly falvoured venison is perfect with a light salad, dressed here with figs and wild mushroom sauce.
To make the vinaigrette, mix together all the ingredients.
For the fig purée, cut the figs in half and remove the pulp, with no white flesh.
Heat the butter in a pan until foaming. Add the five-spice and cook for 2 minutes and then add the flesh of the figs. Add the port and cook for 10-15 minutes.
In a blender, blend until smooth, then pass through a sieve. Finish with a little more butter and season with salt and pepper. Set aside and keep warm.
Season the venison with salt and pepper. Heat a thick bottomed pan with a little oil and 25g/1oz butter. When the butter is foaming, add the venison and cook slowly, colouring all around. Cook for approximately 10 minutes, remove from the pan and leave to rest for 15 minutes before serving.
For the ragoût, using the pan that you cooked the meat in, add a knob of butter and the shallots cooking gently for about 1 minute before adding the mushrooms. Add the chicken stock and cook for 2 minutes. Whisk in the remaining 25g/1oz of butter. Add some vinaigrette to taste and finish with salt, pepper, chopped parsley and a pinch of five spice.
To serve, slice the venison. Put a little fig purée on each plate, put the mushrooms in the middle of the plate and meat on top. Dress the salad leaves lightly in the vinaigrette and scatter them over and around. Pour over a little ragoût and serve .

I inhaled.
I exhaled.
A few seconds later, I was overwhelmed by the drug. The feeling was of urgent distress. I felt stuck, both physically and mentally. I could hardly move, but I crawled towards the balcony to look outside. I looked over at the building across from the one I was in. The wall was bending and swirling. I kept getting higher and higher.
Rocket
brain.
Regret set in, I wished the feeling would go away. As soon as I made the wish I realized it would not come true. I was on a drug, it was taking effect, and I had to bear that effect until it expired. I wanted to make the feeling go away. Throwing up and banging my head against the walls crossed my mind. I didnít do any of these things, I just kept sitting in front of the balcony door, watching the wall swirl and twirl.
Say goodbye
to what you
'know'.
Eventually I stopped getting higher, at which point I gave in to it. I accepted the feeling as part of me for the rest of the trip, and thoroughly enjoyed the comedown.
The secret... let it flow through. I was trying to figure out the feeling... I was trying to gain control over it. Once I realized I had no control... once I gave up and let it push my mind around, I saw some incredible things.
THE DOOR
IS
OPEN NOW.
Everything around was alive, breathing, vibrating, communicating, with me. I was at a friendís house, and his mother has a thing for frogs. There was a stuffed toy frog between me and the balcony door. I looked down at it and it told me a lot about what life at that particular apartment is like. It didnít open itís mouth and speak, no. Just by looking at that frog I got a feel of the permanent mood of the apartment, and the people in it.
Life...
is enigma.
That night I learned quite a few important lessons. In this life, the only thing you actually control is your own reactions to what is happening. Everything else is beyond your control. If you look carefully, a tiny rock on the side of the road could teach you a lot about the journey you are on. Nothing is insignificant.
Open your eyes, open your mind. Look around, at the big big wide picture. At our world, in which everything is the way it is.

A guide to visiting Antarctica: This ice cool destination is an experience like no other
by David McGonigal
Antarctica, a continent covered in pure ice and populated by penguins, is truly the planet's outstanding last frontier. Its isolated position and the fact that it's surrounded by savage oceans has historically protected it from all but the most intrepid visitors.
But that remoteness is rapidly changing. The summer of 2000 was the first season in which Antarctica had more than 10,000 visitors. Indeed, when I first visited in 1995 (on an assignment for an early incarnation of this title) I was one of less than 100,000 people known to ever have seen this mystical land of ice and heroics.
Last summer - almost 25 years later - more than 56,000 people visited the continent, including some 10,000 on large cruise ships not capable of landing passengers. The great majority of visitors (98 per cent) travelled from South America to the Antarctic Peninsula. It's estimated that this coming summer will see almost 80,000 Antarctic visitors and the following summer's visitation may exceed 100,000.
The nature of Antarctic tourism has evolved greatly, too. When Lars-Eric Lindblad, the late pioneering explorer and entrepreneur, took the first 57 tourists to Antarctica in 1966 it was on a basic Argentine navy vessel. The millennium boom was largely on-board Russian research vessels that were comfortable but not luxurious.
Today there are more than 40 new expedition vessels either being built, on the drawing boards, or sailing to Antarctica for their first season that offer unprecedented levels of technology and luxury. Among those new builds coming to Antarctica is Seabourn Venture, which launches in 2021, and Viking has its first expedition vessels on the way. There's also a clear shift to new ships with excellent ice performance, Oceanwide Hondius and Antarctica XXI's MV Magellan Explorer reflecting that trend
What does this all mean for prospective visitors? Well, the food on the ships is much better than the past when providers in Ushuaia, Argentina, the world's southernmost city and the nearest departure point to Antarctica, would deliver crates of soggy lettuces to the dock. Communal bathrooms have given way to marble ensuites and ships use cleaner fuel.
In 2000, 21 ships and yachts landed about 14,000 passengers on Antarctica. This year it's expected that 63 vessels will land more than 59,000 visitors. Much of the Peninsula foreshore comprises sheer cliff faces and towering glaciers with limited landing spots.
Fortunately, there's a system in place to allocate who goes where. Antarctica is controlled by all the nations who have signed on to the Antarctic Treaty. When Antarctic tourism first took off in the early 1990s the operators formed the self-regulating International Association of Antarctica Tour Operators (IAATO).
Each ship comes to Antarctica with each excursion of season pre-booked. Once a ship has reserved a spot another can't book it. However, wind, waves and ice can force a change of plans on the day. Flexibility is lost when every site is booked. And "climate change is giving us more windy days with stronger winds," a veteran polar captain told me.
Darrel Day, the owner and skipper of the yacht Spirit of Sydney, has taken passengers to Antarctica since 1999. "Yachts work outside the IAATO ship scheduler but it's impossible to miss the growth in ship traffic. Anchored at a popular site like Cuverville Island we may see three ships, one after the other, disembarking at that one landing beach."
Several solutions have been suggested, from limiting ships to a single landing each day to allocating a points system to the most popular sites.
Will more tourism affect wildlife? Fortunately, the Antarctic Treaty administration issues detailed guidelines for most sites to minimise impact by stating where and when you can go and how many ships of what size can visit each day.
There's an overriding rule that a maximum of 100 passengers are allowed ashore at one time, plus expedition staff. Ships carrying more than 200 passengers are restricted to certain sites and ships with more than 500 passengers are not permitted to make landings at all.
At a time when polar ships are getting bigger, ships carrying fewer that 100 guests will become the new luxury as everyone will be allowed ashore at once, rather than waiting on staggered landing times.
Every visit to Antarctica is special. Wild and untamed it is so remarkable that, in more than 100 voyages south, I've never met anyone who says they weren't changed by it. From your first iceberg to sailing glaciers-lined bay and being greeted ashore by penguins, it's an unmatched experience. To be in a small rubber boat when a whale surfaces a metre away is unforgettable.
No doubt, those who have already been there will regard themselves as pioneers to dismiss the greater comfort and technological offerings of new generation vessels.
The Antarctic is too expansive and the weather too fickle to ever be tamed. The rapidly growing number of visitors will have to be managed and, as yet, no one has said how that will be achieved. Now really is the time go and, to that end, we provide this detailed guide to how to make it a reality.
David McGonigal, the author of several books on Antarctica, is a polar veteran who has worked as an Antarctic Expedition Leader for more than 20 years and over 100 voyages. He has worked with Peregrine, Quark and One Ocean Expeditions.

TEN TIPS FOR A SUCCESSFUL NEW ERA TRIP TO ANTARCTICA
WHEN TO GO
Summer is the time to visit. Early season has pristine snow, penguins nesting and sea ice; mid-season has penguin chicks; late season has whales and moulting penguins.
CHOOSE THE RIGHT ITINERARY
There are three main routes from South America. The most affordable is the east side of the peninsula. Add extra days for a voyage that crosses the Antarctic Circle. The longest route is to Antarctica via the Falkland Islands and South Georgia Island. Several voyages include the cost of internal or charter flights and some include a flight to Antarctica or the Falklands.
CHOOSE THE RIGHT SHIP
Though fewer in number now there are still some quite basic ships sailing to Antarctica while there are others offering butlers, helicopters and submarines. Visit iaato.org to find links to the websites of member companies and see traveller.com.au/antarctica
CHOOSE THE RIGHT EXCURSIONS
On Antarctic voyages excursions off the ship are included. Though you may need to select (and pay extra) if you wish to use a helicopter, dive, kayak or camp on the ice.
WHAT TO PACK
Everyone thinks Antarctica equals cold but for visitors the Peninsula equates to Australian ski resort cold. But travelling in small boats can be wet. Check if your chosen company supplies wet weather gear. Buy the best Goretex gloves you can find and pack a second pair for when they get wet. Take lots of camera memory.
HOW TO STAY HEALTHY
If you have a proven anti-seasickness remedy, pack it. Or take a range. The crossing south is the worst – it's smooth once you reach the ice and most have "sea legs" for the homeward voyage. Walk within your limitations, whether on a rocking ship or rocky shore. And everyone holds the hand rails so hand sanitise often.
DON'T LEAVE ANTARCTICA WITHOUT ...
SEE
South Georgia has colonies of half a million king penguins, the rugged island is beautiful and Grytviken is the gravesite of legendary explorer Sir Ernest Shackleton.
DO
A Zodiac cruise can be as rewarding as landing. Icebergs are like sculpture gardens and you may see whales and seals up close.
SEE
Most Peninsula voyages come within 100 nautical miles of the Antarctic Circle (66 degrees 33.6 minutes) but only a few voyages cross it. The landscape is different and icier down there and Marguerite Bay is wonderful.
DO
Global warming reveals more crevasses but there are still glaciers safe to climb. The view makes it worthwhile though it's embarrassing to be passed by penguins on the uphill slog.
SEE
Penguins lead simple lives: feed, breed, nest, feed young, fight with neighbours, moult. Watch a colony to understand their lives. Stroppy chinstraps are the most entertaining but Adelies are funny and kings elegant while gentoos emulate Homer Simpson.
DO
The most common mistake first time visitors make is to rush around. Try to put the camera away at least once and just observe.
SEE
Until Christmas it never gets dark so you decide whether it's sunrise or sunset.
DO
At the start of summer, bays may be filled with winter ice. If given the opportunity to walk on it, take it – you'll feel like a true polar explorer.
SEE
Whether on shore or on a Zodiac cruise look into the water to see wildlife from jellyfish to krill – and penguins are graceful underwater.
DO
Spend time in lectures and on the bridge. Each Antarctic voyage has a lot of knowledge on board. An open ship's bridge is a great place to watch wildlife with experts and observe ship operations.


Schema-on-Read
Schema-on-Read leaves the validation of a schema for an Event to the reader. There are several use cases for this pattern, all of which provide a lot of flexibility to Event Processors and Event Sinks:
-
When there are different versions of the same schema type, and the reader wants to choose which version to apply to a given event.
-
When the sequencing matters between events of different types and all those different event types are put into a single stream. For example, consider a banking use case where first a customer opens an account, then gets approval, then makes a deposit, etc. Put these heterogeneous Event types into the same stream, allowing the Event Streaming Platform maintain event ordering and allowing any consuming Event Processor and Event Sinks deserialize the events as needed.
-
When unstructured data is written into an Event Stream, and the reader then applies whichever schema it wants.
Problem
How can an Event Processor apply a schema on the data it is reading from an Event Streaming Platform?
Solution
The Schema-on-Read approach approach enables each reader to decide on how to read data, and which version of which schema to apply to every Event that it reads. To make schema management easier, the design can use a centralized repository that can store multiple versions of different schemas, and then the client applications then choose which schema to apply to events at runtime.
Implementation
With Confluent Schema Registry, all the schemas are managed in a centralized repository. In addition to just storing the schema information, Schema Registry can also be configured to check and/or enforce that schema changes are compatible with previous versions.
For example, if a business started with a schema definition for an event that has 2 fields, but then the business needs evolved to now warrant an optional 3rd field, then that schema evolves with it.
Schema Registry will ensure that the new schema is compatible with the old schema.
In this particular case, for backward compatibility, the 3rd field status
can be defined with a default value which will be used for the missing field when deserializing the data encoded with the old schema.
This ensures that all events in a given stream follow Schema Compatibility rules, and the applications can continue to process those events.
{
"namespace": "example.avro",
"type": "record",
"name": "user",
"fields": [
{"name": "name", "type": "string"},
{"name": "address", "type": "string"},
{"name": "status", "type": "string", "default": "waiting"}
]
}
In another example, if the use case warrants writing different event types into a single stream, with Apache Kafka you could set the "subject naming strategy" to register schemas against the record type, instead of the Kafka topic. Schema Registry will then let Schema Evolution and Schema Compatibility checking to happen within the scope of each event type instead of the topic.
The consumer application can read schema versions assigned to the data type, and in the case where there are different data types in any given stream, the application can cast each event to the appropriate type at processing time and follow the appropriate code path:
if (Account.equals(record.getClass()) {
...
} else if (Approval.equals(record.getClass())) {
...
} else if (Transaction.equals(record.getClass())) {
...
} else {
...
}
Considerations
The schema's subject naming strategy can be set to record type (instead of Kafka topic) in one of two ways.
The less restrictive is RecordNameStrategy
, which sets the namespace to the record, regardless of which topic the event is written to.
The more restrictive is TopicRecordNameStrategy
, which sets the namespace to both, the record and the topic the event is written to.
