Key OO Characteristics
Object"A package of information and descriptions of its manipulation" [Robson]Objects separate interface from implementation, "what" is wanted (on the outside) from "how" it is accomplished (on the inside). This idea of hiding the data inside a package with a fixed set of allowed manipulations is called encapsulation. Why? If the object always selects how to perform a requested manipulation, you guarantee that the procedure and the data it operates on always match. A message denotes an operation that can be performed on an object. The code that describes how to perform an operation on a specific object type is called a method. From the outside, objects receive messages. On the inside, these messages are mapped to methods that perform appropriate actions for the specific kind of object. An object’s interface is the set of messages to which it can respond. For example, several object types may have a "dump" method to cause the object to display its state. Each kind of object will need a unique method to accomplish this. So the message-method idea separates the interface from the implementation. The idea that different kinds of objects might invoke different methods to respond to the same message is called polymorphism. Methods can be bound to messages as soon as the type of the object receiving the message is known (called early binding), or this mapping can wait until run-time (late binding). Some languages (notably C++) make
a syntactic distinction between early and late binding of methods to messages
(virtual functions are bound late, while all others are bound early – at
link time). Smalltalk makes no such distinction. The C++ approach has potentially
dangerous consequences when you manipulate an object through a pointer
to its parent class. If a method of the superclass is virtual, you get
late binding to the appropriate function for the object’s class. On the
other hand, if that method is not virtual, you get early binding to the
parent class’s definition even if the child class has overridden it. Smalltalk
adheres rigorously to the idea that the object itself has sole ownership
of the mapping from methods to messages.

Class"A description of one or more similar objects" [Robson]A specific object described by a particular
class is called an instance of the class.
|
InheritanceA means for creating a new object or class using an existing one as a starting place and defining only what changes. C++ only supports class-based inheritance, but some systems also allow objects to inherit directly from other objects. At minimum, inheritance requires that the child class override its parent’s name. In addition, a child class can:

What C++ Does for you…Name mangling – separation of name spacesThis mechanism – decorating symbol names with extra characters that uniquely identify their class and prototype – is the traditional C++ method for operator overloading, method overloading, and namespace separation. C provides a much smaller set of namespaces than C++ requires, so this strategy allowed C++ to be implemented as a preprocessor for C compilers originally. Rigorous type checking Because of the function prototype requirement and name mangling, a C++ compiler can provide strict type checking for method invocations. Automatic lifetime control Guarantees constructor call upon creation and destructor call upon deletion Multiple Storage classes (same as C) Automatic, static, dynamically allocated Typed dynamic memory management Default constructor, destructor, copy constructor, and assignment operator Explicit early and late binding support And more…

What other OO languages do (or don’t do)Just to make sure we don’t get caught in a C++ centered view of the world, here are some ways other OO systems differ.Run-time type identification This is a Big Deal in C++, but it’s relatively trivial in an interpreted language to know the type of a reference at run-time. Metaclasses Classes are objects, too (Smalltalk, Java?) Garbage collection Java and smalltalk both manage memory for you, freeing objects when they go out of scope or are no longer referenced anywhere. Single Inheritance only Java, Smalltalk 80 Everything is an object Smalltalk Operator overloading Smalltalk makes no distinction between operators and other kinds of messages. The message syntax is flexible enough that you can define operators in the same way as any other kind of message. Visibility control Smalltalk 80 does not appear to provide options for visibility control (based on my quick survey). Instance variables are always private, methods are always public as far as I can tell. Pointers Not in Smalltalk, Java: Both languages deal with objects through implicit references. It is still possible to create data structures, but the language hides much of the memory management work. No Casting As far as I can tell, smalltalk has no equivalent of a C/C++ cast. Late binding Smalltalk makes no syntactic distinction between late and early bound
methods (unlike C++ "virtual" methods)

OO-C framework optionsCovered: objects (encapsulation, explicit construct and destruct), classes, inheritance, polymorphismNot covered: multiple inheritance, automatic initialization / destruction, Strategy 1: message maps and aggregationClass: a struct with a pointer to a method table (message map). Contructor and destuctor are really initializer and destructor, and are invoked manually at beginning and end of lifetime.Messages and methods: mapping table (first cut: use macros like MFC to create a mapping between messages and methods). Alternative: message map can be built at run-time (hash, tree, linked list) – method resolution may be slower. Inheritance: aggregate the parent struct (recursively) at the beginning of the derived one, link the child method table to the parent and search recursively to resolve messages to methods Pros and cons: + flexible and minimal manual steps required
Strategy 3: preprocessor

The big corporations are usually very conservative and in order to change something inside the huge bureaucracy people have to go through many obstacles and justify their decisions.
I wonder how ones could justify that IBM is moving to the Firefox web browser. Whatever the justification is I believe it the positive decision for the word-wide-web and normal people using the web.
Do the corporations still have a passion and not only the financial benefits? Maybe both: complementing each other? That would be an idealistic world.


Man who shot pregnant ex-wife dead with crossbow found guilty
Ramanodge Unmathallegadoo, 51, has been found guilty of murder after bursting into the home of mother-of-five Devi Muhammad and firing an arrow into her stomach
by Emily PenninkA man who shot his heavily pregnant ex-wife dead with a crossbow has been found guilty of murder.
Ramanodge Unmathallegadoo, 51, hid in the shed of mother-of-five Devi Muhammad, formerly known as Unmathallegadoo, armed with two crossbows, bolts, a knife, duct tape, cable ties and a hammer.
When her then partner came out into the garden Unmathallegadoo raced through the open door of the house.
He fired an arrow into Mrs Muhammad's stomach as she fled upstairs.
The 35-year-old suffered catastrophic internal injuries and died while her unborn son was delivered by Caesarean section and miraculously survived.
A jury at the Old Bailey in London had heard how the victim had an arranged marriage to the defendant in Mauritius on her 16th birthday.
He was 30 at the time, nearly twice her age.
Their unhappy relationship ended in 2012 after an incident in which she jumped out of an upstairs window and broke her ankle.
She had told police the defendant had stared at her as he sharpened knives in the garden.
After a trial in 2013, he was cleared of attacking her and acquitted on the judge's direction of a charge of attempted strangulation under the Offences Against the Person Act of 1861.
The victim successfully filed for an emergency non-molestation order which barred the defendant from coming within 100 metres of the family home in Ilford, east London.
Under the order, which was still in place at the time of the killing, Unmathallegadoo was forbidden from contacting his ex-wife directly and was not to threaten or intimidate her or their three children.
Following her divorce, she married builder Imtiaz Muhammad and changed her name to Sana Muhammad.
The couple went on to have two children together and were eagerly awaiting the imminent arrival of their third last autumn.
Meanwhile, the defendant did not react well to his divorce.
He lost his job as a site manager at Newham General Hospital and slept rough as he plotted his revenge.
He bought two crossbows online for around £250 each - an MK-XB 55 Package Red Dot and a Hori-Zone Alfa XT - which were discovered stashed near his ex-wife's home by a neighbour in March 2018.
After they were removed, Unmathallegadoo set about replacing them, and organised surveillance on the house in Applegarth Drive.
On the morning of November 12 2018, he took up position in the garden shed armed with two crossbows, bolts, a knife, duct tape, cable ties and a hammer.
He was disturbed by Mr Muhammad who had gone into the garden to store an empty box while his wife prepared food for a dinner party that evening.
Giving evidence from behind a screen, Mr Muhammad told jurors he thought he was "dreaming" when his wife's ex-husband emerged armed with two loaded crossbows.
He called for his wife to run as he was chased into the house, the court was told.
The widower became emotional as he told jurors: "When she got an arrow she just screamed. I was thinking, 'what is happening?', I was screaming for her.
"Then from there, because he had a second crossbow on his shoulder, I was thinking he's used one and now the second one might be for me."
Afterwards, he told police he was aiming for Mr Muhammad but his former spouse got in the way.
Giving evidence, he claimed the crossbow went off by accident and he bought the weapons to go hunting in Mauritius with his brother.
He told jurors he only wanted to confront Mr Muhammad about his concerns that his daughter was being brought up a Muslim.
But the prosecution argued Unmathallegadoo's ultimate plan had been to restrain the couple and their children and at least kill the two adults and the unborn child.
The jury in Unmathallegadoo's first trial was discharged after a juror raised an issue of psychiatric illness against the judge's direction not to speculate and despite no evidence being heard about his mental state.


Taiwan badminton star treads coachless path to Olympic glory
TAIPEI: Chou Tien-chen is taking the unusual step of gearing up for the 2020 Olympics without a coach, with his longtime physio and confidante shepherding him towards Tokyo gold.
The soft-spoken and boyish 29-year-old, known for pointing to heaven to thank God at the end of a match, parted ways with his trainer early this year.
Since then the world number two has been on a hot streak, winning the men's singles at July's Indonesia Open to claim his first title in a Super 1000 level event.
"I do a lot of homework a coach does before a game and spend more time analysing opponents and what I should do under what circumstances," he told AFP at a recent practice session in Taipei.
Cheering him on from the sidelines has been physiotherapist Victoria Kao, who has shouldered some of the traditional roles of a coach by acting as Chou's mentor, cheerleader and chief critic.
'EMBRACE YOUR DREAMS'
Kao accompanies her charge on and off the court, handing him drinks during match intervals and chaperoning him at charity events.
She says her main job is to "maintain his health and character" in a training regimen that includes pilates and belly dancing sessions.
But Kao said she also has a duty to keep Chou grounded in the wake of his recent winning form.
"I will pour cold water on him and tell him it's just one victory, it's over and you need to calm down," she says.
"But when there are setbacks I will tell him it's okay - embrace your dreams and persist - to try to lift him up emotionally."
Competing in professional badminton without a personal coach is almost unheard of among top players from the sport's traditional Asian powerhouses.
Chou still has access to the Taiwanese coaching team, and regularly consults experts including a retired physics professor on improving his form.
But his decision to take tactical matters into his own hands, with Kao's support, has earned him a series of wins on this year's tour.
He triumphed at the Thailand Open two weeks after his Jakarta victory and took a record third title at the Taipei Open in September in front of rapturous home crowd.
It was in Taipei four years ago that Chou saw off Chinese great Lin Dan in the semi-final and established himself as one of the world's best despite his ultimate loss to Chen Long, who eventually snared Olympic gold at Rio.
Chou hopes to match Chen's feat next year in Tokyo but says he faces an uphill battle.
"There are still a lot of things I need to learn, to improve," he says. "I can't stay at where I am now."
'I WAS PROUD'
Chou credits his current streak to a self-awareness that he lacked when he was younger - something that changed after a health scare in 2013 during a bout of appendicitis.
He dismissed his stomach pains as an anxiety attack and flew to India for a tournament before he was rushed back to Taiwan for surgery. He was told it nearly developed into a life-threatening peritonitis.
"I was a relatively proud person and didn't pay attention to the information other people tried to give me ... but I've come to realise that I can gain more when I am humble," he says.
The sudden death of Korean Olympic medallist Chung Jae-sung last year also prompted a bout of soul-searching.
Off the court he has devoted himself to charity including work with special needs children and teaching badminton to kids in remote parts of Taiwan.
"Life is short so I want to do more things, to contribute more," he said.

FROM RUSSIA WITH LOVE A film review by Steve Rhodes Copyright 1998 Steve Rhodes
RATING (0 TO ****): ***
SPECTRE, up to its old tricks again in the second installment of the Bond series, has its sights set on getting a Russian decoder called a Lektor. Their plan will require the demise of Mr. Bond, which is just fine by their number 1. (We never see number 1's face, only a hand stroking a snow-white cat that perpetually sits in his lap. The credits list him as Ernst Blofeld, but put a "?" where the actor's name should go.)
In 1963's FROM RUSSIA WITH LOVE, SPECTRE lures Bond to Turkey under the ruse that a beautiful young Russian woman named Tatiana Romanova, played fetchingly by Daniela Bianchi, has possession of a Lektor and is willing to turn it over to the West with one proviso. The Western agent accepting it must be James Bond, played this time by an even more confident Sean Connery than in DR. NO. SPECTRE figures Bond will smell a trap but that he will not be able to resist coming, what with the chance of bedding a beautiful lass and getting a decoder as a bonus prize.
Tatiana, being a loyal Russian is similarly duped by former KGB agent Rosa Klebb (Lotte Lenya) into thinking the operation is a Russian one to trap Bond. Actually Rosa is number 3 in the SPECTRE hierarchy.
This is the first Bond film in which he gets his now normal assortment of gadgets before his mission.  The tear gas canister, for example, explodes in the face of someone attempting to break into the briefcase.
Featured attractions of the Bond films are the exotic locales -- Istanbul and Venice are prominently featured this time, especially the spires of their skylines which seem to reach for the heavens. Along with the images comes more great Bond music by composer John Barry.
FROM RUSSIA WITH LOVE contains easily one of the hokiest scenes of any Bond film. Two gypsy girls -- they'd probably be referred to as young women today -- engage in an incredibly fake wrestling match to see who will win the honor of marrying the chief's son. Fortuitously, Robert Shaw, playing SPECTRE's chief hunk Red Grant, and his fellow goons show up to shoot up the place in the hope of taking out Bond. Surprise, Bond lives, but at least the wrestling farce is broken up.
Unlike the first movie, DR. NO, which rarely flagged, this one has too many slow parts that fail to keep the viewers' attention. But any Bond film starring Connery remains a delight to watch.
In my favorite small scene, we learn of one of the few times that Bond missed a clue. "'Red wine with fish' that should have told me something," Bond laments. Clearly a character who orders red wine with his fish should have been suspected right away.
FROM RUSSIA WITH LOVE runs 1:50. It is rated PG for violence and sexual innuendo and would be fine for kids around nine and up.
My son Jeffrey, almost 9, thought FROM RUSSIA WITH LOVE was a really good movie but liked DR. NO, the only other Bond film he has seen, much better. And again, his only complaint was that it had too much kissing.

Bursa Malaysia to launch new organisational structure
by BernamaKUALA LUMPUR (Nov 21): Bursa Malaysia Bhd has announced its plan for an organisational restructure, effective Jan 1, 2020.
In a statement today, it said the new structure will flatten the organisation and future proof the exchange in light of the fast-evolving and challenging operational and regulatory landscape.
“It is incumbent on the exchange to make these changes to better serve their customers and stakeholders, fulfilling their vision of becoming ASEAN’s leading responsible and globally connected marketplace,” said chief executive officer Datuk Muhamad Umar Swift.


'3BlackChicks Review...'
VERTICAL LIMIT (2000) Rated PG-13; running time 126 minutes Genre: Action Seen at: Celebration Cinema (Lansing, Michigan) Official site: http://www.spe.sony.com/movies/verticallimit/ IMDB site: http://us.imdb.com/Details?0190865 Written by: Robert King, Terry Hayes Directed by: Martin Campbell Cast: Chris O'Donnell, Bill Paxton, Scott Glenn, Robin Tunney, Izabella Scorupco, Nicholas Lea, Alexander Siddig
Review Copyright Rose Cooper, 2000 Review URL: http://www.3blackchicks.com/bamsvertical.html
By all rights, I shouldn't have liked VERTICAL LIMIT. After all, Action Flicks usually aren't my thing, especially mindless (or, in the case of this movie, overly-earnest almost to the point of unbelievability) Action Flicks. So it came as a shock to me when I realized that not only did I like this movie, I was thrilled, and even *surprised*, by it.
 And boy, whadda ride...
The Story (WARNING: **spoilers contained below**): Our Earnest Young Hero, mountain-climber Peter Garrett (Chris O'Donnell) is estranged from his fellow mountain-climbing sister Annie (Robin Tunney) after a tragic accident involving their father (Stuart Wilson) leaves Peter not ever wanting to climb again. Peter learns that Annie has joined the climbing crew of mega-billionaire Elliot Vaughn (Bill Paxton), an eccentric adventurer who's using the planned climb up the Really Big Mountain called "K2" as a publicity stunt coinciding with the inaugural flight of his Majestic Airlines [Richard Branson...calling Virgin Airlines' Richard Branson...]
Of course, Vaughn, an Evil Megalomaniac in disguise, has a Secret, one which involves the Wizened Mystic climber Montgomery Wick (Scott Glenn), who has plans of his own for the Evil Megalomaniac once Wick finds out that Vaughn plans to go up K2 with a climbing team, led by Best Damn Climber Tom McLaren (Nicholas Lea).
But when something goes Terribly Wrong with the climb, Earnest Peter insists on rescuing his now-Damsel In Distress sister and company, enlisting the aide of Wizened Mystic Wick, Comic Relief Aussie Dudes Malcolm and Cyril (sorry; I can't find their credits listed *anywhere*), Sensitive And Prayerful Guide Kareem (Alexander Siddig), and Medic climber (and Peter's potential Warm Place To Put It) Monique Aubertine (Izabella Scorupco).
Don't be fooled though: despite what the credits say, Chris O'Donnell isn't really the star of this show. No, the *real* focal point of this flick is the mountain itself; K2, in all its treacherous glory, was far and away the big kahuna here.
The Upshot: If my rampant capitalization of those characterizations make me seem cynical about all the Types that make up the characters of VERTICAL LIMIT, it's because my genuine liking of this flick really surprised me. In my book, there's little about the mix of an Earnest Young Hero, a Damsel In Distress, an Evil Megalomaniac, an Wizened Mystic, etc., that should Do It for me. But yet, it did; *they* did. Or, perhaps more correctly, the mixologists - director Martin Campbell and cinematographer David Tattersall - thrilled me with Gee Whiz action shots galore.
The audience never had time to fret over the relatively-transparent plotline, because whenever there was a moment to sit there and think "hey, waaaait a minute...", **BOOM**! you're hit with something new comin' 'round the mountain. This kind of plotting couldn't hold the movie up by itself - there's only so much Thrilling Action one can take, even as good as "Limit"'s Thrilling Action was. Fortunately for VERTICAL LIMIT, a few of its characters - namely Bill Paxton's Vaughn, the surprisingly well-used (and no, not That Way) Monique, and humorous brother climbers Malcolm and Cyril - added a whiff of credible storyline to the action surrounding them.
There are brief subplots involving the Pakistani army (as a plothole-filled excuse to use devices which go **BOOM** way easily) and one character's great need for Revenge, both of which strain the viewer's ability to suspend disbelief just up to the point where Big! Action! comes into play again. I was able to work around it; some viewers may not be able to do so.
VERTICAL LIMIT is one of those rare Action Flicks that overcomes (if not transcends) the genre in which it resides; it maintains its high excitement level throughout, keeps the viewer guessing about what comes next, and even lets its supporting characters have more interesting bits than the so-called stars have. If only for its potentially big surround-sound thump, VERTICAL LIMIT is most def on my "can't wait till it's on DVD" list.
Bammer's Bottom Line: "Story? We don' need no steenkin' story!"  If you don't mind a see-through plotline and story resolution you can predict from a mile away, VERTICAL LIMIT is the Action Flick to catch this season.
 I'll leave that one to the movie.

13. Concurrency
Objects are abstractions of processing. Threads are abstractions of schedule.
-- James O. Coplien
Why Concurrency
"Concurrency is a decoupling strategy. It helps us decouple what gets done from when it gets done."
"From a structural point of view the application looks like many little collaborating computers rather than one big main loop. This can make the system easier to understand and offers some powerful ways to separate concerns."
"But structure is not the only motive for adopting concurrency. Some systems have time and throughput constraints that require hand-coded concurrent solutions."
Myths and Misconceptions
"Concurrency always improves performance.
Design does not change when writing concurrent programs.
Understanding concurrency issues is not important when working with a container such as Web or EJB container."
"Here are a few more balanced sound bites regarding writing concurrent software:
Concurrency incurs som overhead, both in performance as well as writing additional code.
Correct concurrency is complex, even for simple problems.
Concurrency bugs aren't usually repeatable, so they are often ignored as one-offs instead of the true defects they are.
Concurrency often requires a fundamental change in design strategy."
Challenges
"there are many possible paths that the two threads can take [...], and some of those paths generate incorrect results."
"Of course most of those paths generate valid results. The problem is that some of them don't."
Single Responsibility Principle
"Concurrency-related code has its own life cycle of development, change and tuning.
Concurrency-related code has its own challenges [...]
The number of ways in which miswritten concurrency-based code can fail makes it challenging enough [...]"
"Recommendation: Keep your concurrency-related code separate from other code"
Corollary: Limit the Scope of Data
"two threads modifying the same field of a shared object can interfere with each other, causing unexpected behavior."
"Recommendation: Take data encapsulation to heart; severely limit the access of any data that may be shared."
Corollary: Use Copies of Data
"A good way to avoid shared data is to avoid sharing the data in the first place. In some situations it is possible to copy objects and treat them as read-only. In other cases it might be possible to copy objects, collect results from multiple threads in these copies and then merge the results in a single thread."
Corollary: Threads Should Be as Independent as Possible
"Consider writing your threaded code such that each thread exists in its own world, sharing no data with any other thread."
"Recommendation: Attempt to partition data into independent subsets that can be operated on by independent threads, possibly in different processors."
[!] [I had skipped a one page content presenting Java solutions to avoid concurrency problems. Search these parts in the book if interested. I don't plan to dive into different programming languages for now.]
Know Your Execution Models
"Bound Resources - Resources of a fixed size of number used in a concurrent environment."
"Mutual Exclusion - Only one thread can access shared data or a shared resource at a time."
"Starvation - One thread or a group of threads is prohibited from proceeding for an excessively long time or forever."
"Deadlock - Two or more threads waiting for each other to finish. Each thread has a resource that the other thread requires and neither can finish until it gets the other resource."
"Livelock - Threads in lockstep, each trying to do work but finding another "in the way". Due to resonance, threads continue trying to make progress but are unable to for an excessively long time - or ferever."
Producer-Consumer
"One or more producer threads create some work and place it in a buffer or queue. One or more consumer threads acquire that work from the queue and complete it. The queue between the producers and consumers is a bound resource. This means producers must wait for free space in the queue before writing and consumers must wait until there is something in the queue to consume."
Readers-Writers
"When you have a shared resource that primarily serves as a source of information for readers, but which is occasionally updated by writers, throughput is an issue."
"A simple strategy makes writers wait until there are no readers before allowing the writer to perform an update. If there are continuous readers, however, the writers will be starved. On the other hand, if there are frequent writers and they are given priority, throughput will suffer."
Dining Philosophers
"Imagine a number of philosophers sitting around a circular table. A fork is placed to the left of each philosopher. There is a big owl of spaghetti in the center of the table. The philosophers spend their time thinking unless they get hungry. Once hungry, they pick up the forks on either side of them and eat. A philosopher cannot eat unless he is holding two forks. If the philosopher to his right or left is already using one of the forks he needs, h must wait until philosopher finishes eating and puts the forks back down. Once a philosopher eats, he puts both his forks back down on the table and waits until he is hungry again."
Beware Dependencies Between Synchronized Methods
"Avoid using more than one method on a shared object."
"Client-Based Locking - Have the client lock the server before calling the first method and make sure the lock's extent includes code calling the last method."
"Server-Based Locking - Within the server create a method that locks the server, calls all the methods, and then unlocks. Have the client call the new method."
"Adapted Server - create an intermediary that performs the locking. This is an example of server-based locking, where the original server cannot be changed."
Keep Synchronized Sections Small
"All sections of code guarded by the same lock are guaranteed to have only one thread executing through them at any given time. Locks are expensive because they create delays and add overhead."
"However, expending synchronization beyond the minimal critical sections increases contention and degrades performance."
Writing Correct Shut-Down Code Is Hard
"Graceful shutdown can be hard to get correct. Common problem involve deadlock, with threads waiting for a signal to continue that never comes."
"So if you must write concurrent code that involves shutting down gracefully, expect to send much of your time getting the shut-down to happen correctly."
"Think about shut-down early and get it working early."
Testing Threaded Code
"Write tests that have the potential to expose problems and then run them frequently, with different programatic configurations and system configurations and load. If tests ever fail, track down the failure."
Treat Spurious Failures as Candidate Threading Issues
"Bugs in threaded code might exhibit their symptoms once in a thousand, or a million, executions."
"It is best to assume that on-offs [e.g. cosmic ray, hardware glitch, and so on] do not exist. The longer these "on-offs" are ignored, the more code is built on top of a potentially faulty approach."
Get Your Nonthreaded Code Working First
"Do not try to chase down nonthreading bugs and threading bugs at the same time. Make sure your code works outside of threads."
Make Your Threaded Code Pluggable
"Write the concurrency-supporting code such that it can be run in several configurations:
One thread, several threads, varied as it executes
Threaded code interacts with something that can be both real or a test double.
Execute with test doubles that run quickly, slowly, variable.
Configure tests so they can run for a number of iterations."
Make Your Threaded Code Tunable
"Early on, find ways to time the performance of your system under different configurations. Allow the number of threads to be easily tuned. Consider allowing it to change while the system is running. Consider allowing self-tuning based on throughput and system utilization."
Run with More Threads Than Processors
"The more frequently your tasks swap, the more likely you'll encounter code that is missing a critical section or causes deadlock."
Run on Different Platforms
"different operating systems have different threading policies, each of which impacts the code's execution."
"Run your threaded code on all target platforms early and often."
Instrument Your Code to Try and Force Failures
"How might you increase your chances of catching such rare occurrences? You can instrument your code and force it to run in different orderings by adding calls to methods like Object.wait(), Object.sleep(), Object.yield() and Object.priority()."
Hand-Coded
"You can insert calls to wait(), sleep(), yield(), and priority() in your code by hand."
"What we need is a way to do this during testing but not in production. We also need to easily mix up configurations between different runs, which results in increased chances of finding errors in the aggregate."
Automated
"You could use tools like an Aspect-Oriented Framework, CGLIB, or ASM to programmatically instrument your code."
"use a simple aspect that randomly selects among doing nothing, sleeping, or yielding."
"Use jiggling strategies to ferret out errors."

Woman, 2 grandsons killed by train at gate-less crossing
by Associated PressJUPITER, Fla. (AP) — Authorities say a 58-year-old Florida woman and her two grandsons were killed by a passing Amtrak train as she drove the Cub Scouts to an overnight camping trip.
The Palm Beach Post reports the train collided with their Subaru Outback on Saturday at a gate-less railroad crossing near the entrance to a wildlife management area.
An incident report says the train dragged the vehicle for a half-mile, killing Valery Jo Rintamaki, 10-year-old Tristan Prestano and 8-year-old Skyler Prestano. Camping gear was strewn along the tracks.
No one on the train was injured.
The boys’ grandfather David Peat said he was shocked to find the crossing doesn’t have a gate, flashing lights or a stop sign. He took his concerns to state Rep. Matt Willhite, who vowed Sunday to investigate.
