• Threading Overview

  - by ACShorten

  One of the major features of the batch framework is the ability to support multi-threading. The multi-threading support allows a site to increase throughput on an individual batch job by splitting the total workload across multiple individual threads. This means each thread has fine level control over a segment of the total data volume at any time. The idea behind the threading is based upon the notion that "many hands make light work". Each thread takes a segment of data in parallel and operates on that smaller set. The object identifier allocation algorithm built into the product randomly assigns keys to help ensure an even distribution of the numbers of records across the threads and to minimize resource and lock contention. The best way to visualize the concept of threading is to use a "pie" analogy. Imagine the total workset for a batch job is a "pie". If you split that pie into equal sized segments, each segment would represent an individual thread. The concept of threading has advantages and disadvantages: Smaller elapsed runtimes - Jobs that are multi-threaded finish earlier than jobs that are single threaded. With smaller amounts of work to do, jobs with threading will finish earlier. Note: The elapsed runtime of the threads is rarely proportional to the number of threads executed. Even though contention is minimized, some contention does exist for resources which can adversely affect runtime. Threads can be managed individually – Each thread can be started individually and can also be restarted individually in case of failure. If you need to rerun thread X then that is the only thread that needs to be resubmitted. Threading can be somewhat dynamic – The number of threads that are run on any instance can be varied as the thread number and thread limit are parameters passed to the job at runtime. They can also be configured using the configuration files outlined in this document and the relevant manuals.Note: Threading is not dynamic after the job has been submitted Failure risk due to data issues with threading is reduced – As mentioned earlier individual threads can be restarted in case of failure. This limits the risk to the total job if there is a data issue with a particular thread or a group of threads. Number of threads is not infinite – As with any resource there is a theoretical limit. While the thread limit can be up to 1000 threads, the number of threads you can physically execute will be limited by the CPU and IO resources available to the job at execution time. Theoretically with the objects identifiers evenly spread across the threads the elapsed runtime for the threads should all be the same. In other words, when executing in multiple threads theoretically all the threads should finish at the same time. Whilst this is possible, it is also possible that individual threads may take longer than other threads for the following reasons: Workloads within the threads are not always the same - Whilst each thread is operating on the roughly the same amounts of objects, the amount of processing for each object is not always the same. For example, an account may have a more complex rate which requires more processing or a meter has a complex amount of configuration to process. If a thread has a higher proportion of objects with complex processing it will take longer than a thread with simple processing. The amount of processing is dependent on the configuration of the individual data for the job. Data may be skewed – Even though the object identifier generation algorithm attempts to spread the object identifiers across threads there are some jobs that use additional factors to select records for processing. If any of those factors exhibit any data skew then certain threads may finish later. For example, if more accounts are allocated to a particular part of a schedule then threads in that schedule may finish later than other threads executed. Threading is important to the success of individual jobs. For more guidelines and techniques for optimizing threading refer to Multi-Threading Guidelines in the Batch Best Practices for Oracle Utilities Application Framework based products (Doc Id: 836362.1) whitepaper available from My Oracle Support

• Font gets enlarged when rotating screen

  - by queueoverflow

  I have a new ThinkPad X220 Tablet with Kubuntu 12.04.

• Kinetic Scroll in Maverick

  - by Shoaib

  I have Sony VAIO FW 230J laptop. I was using Lucid and upgraded my system to Maverick beta in September 2010. Although there were few issues with beta release on my system although I did not felt myself in any deadlock. The most notable experience on my ubuntu was the smooth and kinetic scrolling and very sensitive touch pad experience with finer control that was oddly normal in previous releases and even on windows 7 currently. Definitely this release of ubuntu is improved for touch UI experience. I believe that this is magic of 10.10. For my official system I waited until the final release was out. After installing (upgrading) official system to Maverick I am not feeling the same smooth and kinetic scroll experience. My laptop has Graphics: Intel DMA-X4500MHD while my official desktop has Graphics: Intel DMA-X4500HD Do I need to install or update some software package to have similar kinetic scroll experience?

• problem in array of shooter sprites which contain different colour bubbles

  - by prakash s

  everyone i am developing bubble shooter game in cocos2d I have placed shooter array which contain different color bubbles like this 00000000 it is 8 bubbles array if i tap the screen, first bubbles should move for shooting the target .png .And if i again tap the screen again 2nd position bubble should move for shooting the target.png bubbles,how it will possible for me because i have already created the array of target which contain different color bubbles, here i write the code : - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { // Choose one of the touches to work with UITouch *touch = [touches anyObject]; CGPoint location = [touch locationInView:[touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; // Set up initial location of projectile CGSize winSize = [[CCDirector sharedDirector] winSize]; NSMutableArray * movableSprites = [[NSMutableArray alloc] init]; NSArray *images = [NSArray arrayWithObjects:@"1.png", @"2.png", @"3.png", @"4.png",@"5.png",@"6.png",@"7.png", @"8.png", nil]; for(int i = 0; i < images.count; ++i) { int index = (arc4random() % 8)+1; NSString *image = [NSString stringWithFormat:@"%d.png", index]; CCSprite*projectile = [CCSprite spriteWithFile:image]; //CCSprite *projectile = [CCSprite spriteWithFile:@"3.png" rect:CGRectMake(0, 0,256,256)]; [self addChild:projectile]; [movableSprites addObject:projectile]; float offsetFraction = ((float)(i+1))/(images.count+1); //projectile.position = ccp(20, winSize.height/2); //projectile.position = ccp(18,0 ); //projectile.position = ccp(350*offsetFraction, 20.0f); projectile.position = ccp(10/offsetFraction, 20.0f); // projectile.position = ccp(projectile.position.x,projectile.position.y); // Determine offset of location to projectile int offX = location.x - projectile.position.x; int offY = location.y - projectile.position.y; // Bail out if we are shooting down or backwards if (offX <= 0) return; // Ok to add now - we've double checked position //[self addChild:projectile]; // Determine where we wish to shoot the projectile to int realX = winSize.width + (projectile.contentSize.width/2); float ratio = (float) offY / (float) offX; int realY = (realX * ratio) + projectile.position.y; CGPoint realDest = ccp(realX, realY); // Determine the length of how far we're shooting int offRealX = realX - projectile.position.x; int offRealY = realY - projectile.position.y; float length = sqrtf((offRealX*offRealX)+(offRealY*offRealY)); float velocity = 480/1; // 480pixels/1sec float realMoveDuration = length/velocity; // Move projectile to actual endpoint [projectile runAction:[CCSequence actions: [CCMoveTo actionWithDuration:realMoveDuration position:realDest], [CCCallFuncN actionWithTarget:self selector:@selector(spriteMoveFinished:)], nil]]; // Add to projectiles array projectile.tag = 1; [_projectiles addObject:projectile]; } }

• First time android game development [on hold]

  - by Dave

  My friend and i are developing a android game. This is my first time develop android game, so we don't know how to code The game is 2d game and we develop it without 3rd party engine / framework. Now we got a few questions, hope you can help us. In game play, using 'Surfaceview' only to achieve it. Is it best practice? On 'Surfaceview', a lot of difference button(Menu, pause, game object..etc) is on it, but I don't know how to code it? (actually, i have already done, but...so stupid way. Detect the user touch position (x, y) to identify where they touch[rect(x1,y1,x2,y2).contain(x,y)] Is it right? Teach me how to do if wrong. View / Surfaceview / OpenGL, which is suitable for us? (if like Tetris) Thank you for your help. Ps: My english is not good, hope you can understand what i mean.

• Disabling Navigation Flicks in WPF

  - by Brian Genisio's House Of Bilz

  I am currently working on a multi-touch application using WPF.  One thing that has been irritating me with this development is an automatic navigation forward/back command that is bound to forward and backwards flicks.  Many of my touch-based interactions were being thwarted by gestures picked up by WPF as navigation.  I just wanted to disable this behavior. My programmatic back/forward calls are not affected by this change, which is nice.  Here is how I did it:  In my main window, I added the following command bindings:<NavigationWindow.CommandBindings> <CommandBinding Command="NavigationCommands.BrowseBack" Executed="DoNothing" /> <CommandBinding Command="NavigationCommands.BrowseForward" Executed="DoNothing" /> </NavigationWindow.CommandBindings> Then, the DoNothing method in the code-behind does nothing:private void DoNothing(object sender, ExecutedRoutedEventArgs e) { } There may be a better way to do this, but I haven’t found one.

• 5 Android Keyboard Replacements to Help You Type Faster

  - by Chris Hoffman

  Android allows developers to replace its keyboard with their own keyboard apps. This has led to experimentation and great new features, like the gesture-typing feature that’s made its way into Android’s official keyboard after proving itself in third-party keyboards. This sort of customization isn’t possible on Apple’s iOS or even Microsoft’s modern Windows environments. Installing a third-party keyboard is easy — install it from Google Play, launch it like another app, and it will explain how to enable it. Google Keyboard Google Keyboard is Android’s official keyboard, as seen on Google’s Nexus devices. However, there’s a good chance your Android smartphone or tablet comes with a keyboard designed by its manufacturer instead. You can install the Google Keyboard from Google Play, even if your device doesn’t come with it. This keyboard offers a wide variety of features, including a built-in gesture-typing feature, as popularized by Swype. It also offers prediction, including full next-word prediction based on your previous word, and includes voice recognition that works offline on modern versions of Android. Google’s keyboard may not offer the most accurate swiping feature or the best autocorrection, but it’s a great keyboard that feels like it belongs in Android. SwiftKey SwiftKey costs $4, although you can try it free for one month. In spite of its price, many people who rarely buy apps have been sold on SwiftKey. It offers amazing auto-correction and word-prediction features. Just mash away on your touch-screen keyboard, typing as fast as possible, and SwiftKey will notice your mistakes and type what you actually meant to type. SwiftKey also now has built-in support for gesture-typing via SwiftKey Flow, so you get a lot of flexibility. At $4, SwiftKey may seem a bit pricey, but give the month-long trial a try. A great keyboard makes all the typing you do everywhere on your phone better. SwiftKey is an amazing keyboard if you tap-to-type rather than swipe-to-type. Swype While other keyboards have copied Swype’s swipe-to-type feature, none have completely matched its accuracy. Swype has been designing a gesture-typing keyboard for longer than anyone else and its gesture feature still seems more accurate than its competitors’ gesture support. If you use gesture-typing all the time, you’ll probably want to use Swype. Swype can now be installed directly from Google Play without the old, tedious process of registering a beta account and sideloading the Swype app. Swype offers a month-long free trial and the full version is available for $1 afterwards. Minuum Minuum is a crowdfunded keyboard that is currently still in beta and only supports English. We include it here because it’s so interesting — it’s a great example of the kind of creativity and experimentation that happens when you allow developers to experiment with their own forms of keyboard. Minuum uses a tiny, minimum keyboard that frees up your screen space, so your touch-screen keyboard doesn’t hog your device’s screen. Rather than displaying a full keyboard on your screen, Minuum displays a single row of letters.  Each letter is small and may be difficult to hit, but that doesn’t matter — Minuum’s smart autocorrection algorithms interpret what you intended to type rather than typing the exact letters you press. Just swipe to the right to type a space and accept Minuum’s suggestion. At $4 for a beta version with no trial, Minuum may seem a bit pricy. But it’s a great example of the flexibility Android allows. If there’s a problem with this keyboard, it’s that it’s a bit late — in an age of 5″ smartphones with 1080p screens, full-size keyboards no longer feel as cramped. MessagEase MessagEase is another example of a new take on text input. Thankfully, this keyboard is available for free. MessagEase presents all letters in a nine-button grid. To type a common letter, you’d tap the button. To type an uncommon letter, you’d tap the button, hold down, and swipe in the appropriate direction. This gives you large buttons that can work well as touch targets, especially when typing with one hand. Like any other unique twist on a traditional keyboard, you’d have to give it a few minutes to get used to where the letters are and the new way it works. After giving it some practice, you may find this is a faster way to type on a touch-screen — especially with one hand, as the targets are so large. Google Play is full of replacement keyboards for Android phones and tablets. Keyboards are just another type of app that you can swap in. Leave a comment if you’ve found another great keyboard that you prefer using. Image Credit: Cheon Fong Liew on Flickr

• How does btrfs RAID work in degraded mode?

  - by turbo

  My idea was that (using loopback devices) it works like this Create the raid array sudo mkfs.btrfs -m raid1 -d raid1 /dev/loop1 /dev/loop2 You mount them sudo mount /dev/loop1 /mnt and mark them touch goodcondition You unmount and simulate disk failure (remove disk or delete loopback device loop2 in my case) You mount degraded -o degraded and mark again touch degraded You add the bad disk again sudo btrfs dev add /dev/loop2 You rebalance sudo btrfs fi ba /mnt And Raid 1 should work again. But that's not the case. sudo btrfs fi show: Total devices 3 FS bytes used 28.00KB devid 3 size 4.00GB used 264.00MB path /dev/loop1 devid 2 size 4.00GB used 272.00MB path /dev/loop2 *** Some devices missing The file degraded lives on loop1 but not on loop2 when loop2 is mounted in degraded mode. Why is that?

• Commerce, Anyway You Want It

  - by David Dorf

  I believe our industry is finally starting to realize the importance of letting consumers determine how, when, and where to interact with retailers.  Over the last few months I've seen several articles discussing the importance of removing the barriers between existing channels. Paula Rosenblum of RSR first brought the term omni-channel to my attention back in September. She stated, "omni-channel retail isn’t the merging of channels – rather, it’s the use of all possible channels (present and future) to enhance the customer experience in a profitable way." I added to her thoughts in this blog posting in which I said, "For retailers to provide an omni-channel experience, there needs to be one logical representation of products, prices, promotions, and customers across all channels. The only thing that varies is the presentation of the content based on the delivery mechanism (e.g. shelf labels, mobile phone, web site, print, etc.) and often these mechanisms can be combined in various ways." More recently Brian Walker of Gartner suggested we stop using the term multi-channel and begin thinking more about consumer touch-points. "It is time for organizations to leave their channel-oriented ways behind, and enter the era of agile commerce--optimizing their people, processes and technology to serve today's empowered, ever-connected customers across this rapidly evolving set of customer touch points." Now Jason Goldberg, better known as RetailGeek, says we should start breaking down the channel silos by re-casting the VP of E-Commerce as the VP of Digital Marketing, and change his/her focus to driving sales across all channels using digital media. This logic is based on the fact that consumers switch between channels, or touch-points as Brian prefers, as part of their larger buying process. Today's smart consumer leverages the Web, mobile, and stores to provide the best shopping experience, so retailers need to make this easier. Regardless of what we call it, the key take-away is that "multi-channel" is not only an antiquated term but also an idea who's time has passed.  Today, retailers must look at e-commerce, m-commerce, f-commerce, catalogs, and traditional store sales collectively and through the consumers' eyes.  The goal is not to drive sales through each channel but rather to just drive sales -- using whatever method the customer prefers.  There really should be just one cart.

• Curiosity on any Smartphones that Run on Android 2.3.3 with Different Screen Reoslution

  - by David Dimalanta

  I have a question regarding about any smartphones that run only in Android 2.3.3. Is the size of screen or the screen resolution is always HVGA or does it have capable of running this OS (Android 2.3.3) on big screen size (4" to 5") at about 720x1280? I'm thinking of the game's compatibility depending on the version of the Android OS and the screen resolution, which affects the change of coordinates especially for assigning touch buttons and drag-n-drop at exact location, before I'm gonna decide to make one. My program works on the Android 4 ICS and Jellybean, however, will that work on Android 2.3.3 in spite of precise touch coordinate or just dependent on the screen resolution (regardless how large it is) as the X and Y coordinate? And take note, I'm using Eclipse IDE for Java developers.

• How do I improve my ability to manipulate code quickly, not wpm?

  - by Steve Moser

  I have seen several questions on here about touch typing and words per minute but not about improving ones ability to manipulate text using keyboard shortcuts, bindings etc. I have tried putting a cheat sheet of keyboard shortcuts next to my monitor but I can never incorporate them in my 'flow'. I have also tried the 'just use vi and don't touch the mouse' method but that only helps me with navigating code and not editing. I would prefer to use some application (or game) to learn text manipulation. But it looks like nothing like that exists (app idea?). I'm open to other suggestions too.

• Is there a way to emulate pinch-zoom?

  - by aking1012

  I'm looking for a way to emulate pinch zoom in either an android emulator(android SDK-less desirable) or a (preferred) native Ubuntu web browser that I can resize to a specified size for initial testing of HTML5 applications. This is would be useful for first round testing during cross-platform application development. Note: I'm trying to do this with no real touch-device only a mouse. So the best answer would be something like "Install this chromium plug-in and use this hotkey to set pinch points" or something similar. We already have this for getting dual mouse working(thanks AmithKK). The browser that supports multi-touch is the hard part. Something to note is that I start getting screen artifacts using multiple mice via that guide. They're mild and tolerable, but they are there.

• Collision in PyGame for spinning rectangular object.touching circles

  - by OverAchiever

  I'm creating a variation of Pong. One of the differences is that I use a rectangular structure as the object which is being bounced around, and I use circles as paddles. So far, all the collision handling I've worked with was using simple math (I wasn't using the collision "feature" in PyGame). The game is contained within a 2-dimensional continuous space. The idea is that the rectangular structure will spin at different speed depending on how far from the center you touch it with the circle. Also, any extremity of the rectangular structure should be able to touch any extremity of the circle. So I need to keep track of where it has been touched on both the circle and the rectangle to figure out the direction it will be bounced to. I intend to have basically 8 possible directions (Up, down, left, right and the half points between each one of those). I can work out the calculation of how the objected will be dislocated once I get the direction it will be dislocated to based on where it has been touch. I also need to keep track of where it has been touched to decide if the rectangular structure will spin clockwise or counter-clockwise after it collided. Before I started coding, I read the resources available at the PyGame website on the collision class they have (And its respective functions). I tried to work out the logic of what I was trying to achieve based on those resources and how the game will function. The only thing I could figure out that I could do was to make each one of these objects as a group of rectangular objects, and depending on which rectangle was touched the other would behave accordingly and give the illusion it is a single object. However, not only I don't know if this will work, but I also don't know if it is gonna look convincing based on how PyGame redraws the objects. Is there a way I can use PyGame to handle these collision detections by still having a single object? Can I figure out the point of collision on both objects using functions within PyGame precisely enough to achieve what I'm looking for? P.s: I hope the question was specific and clear enough. I apologize if there were any grammar mistakes, English is not my native language.

• problems programmatically creating UIView on iPad App

  - by user3871

  I have been struggling with this problem for a few days. My iPad app is designed to be a portrait game. To satisfy Apple's expection, I also support landscape mode. When it goes into landscape mode, the game goes into a letterbox format with back borders on the sides. My problem is I am creating the UIWindow and UIView programmatically. For some unkown reason, the touch controls are "locked" in to think I'm always in landscape mode. And even though visually in portrait mode everything looks correct, the top and bottom of the screen does not respond to touch. To summarize how I am setting this up, let me provide the skeletal framework of what I'm doing: in main.cpp: int retVal = UIApplicationMain(argc, argv, nil, @"derbyPoker_ipadAppDelegate"); In the delegate, I am doing this: - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { CGRect screenBounds = [[UIScreen mainScreen] bounds]; CGFloat scale = [[ UIScreen mainScreen] scale ]; m_device_width = screenBounds.size.width; m_device_height = screenBounds.size.height; m_device_scale = scale; // Everything is built assuming 640x960 window = [[ UIWindow alloc ] initWithFrame:[[UIScreen mainScreen] bounds]]; viewController = [ glView new ]; [self doStateChange:[blitz class]]; return YES; } The last bit of code sets up the UIView... - (void) doStateChange: (Class) state{ viewController.view = [[state alloc] initWithFrame:CGRectMake(0, 0, m_device_width, m_device_height) andManager:self]; viewController.view.contentMode = UIViewContentModeScaleAspectFit; viewController.view.autoresizesSubviews = YES; [window addSubview:viewController.view]; [window makeKeyAndVisible]; } The problem seems to related to the line viewController.view.contentMode = UIViewContentModeScaleAspectFit; If I remove that line, touch works correctly in portrait mode. But the negative is when I'm landscape mode, the game stretches incorrectly. So That's not a option. The frustrating thing is, when I originally had this set up with a NIB file, it worked fine. I have read through the docs about UIWindow, UIViewController and UIView and have tried about everything to no avail. Any help would be greatly appreciated.

• How do I increase the touchpad sensitivity on Acer Aspire One 532h?

  - by Yossi Farjoun

  I got a cheap netbook and put ubuntu on it without even booting into the windows it came with. I am now slightly regretting it since the trackpad is very annoying, it only registers when I press quite hard on it, and even then the motion is so slow that I must drag me poor finger 3 times to get the pointer to move up or down that tiny screen. OK. enough rant. now business: I went into the setting and increase sensitivity and acceleration to high. No difference. the behaviour did not change at all. So now my questions are: Is this a hardware problem? Is there a program I can run to see what input the trackpad is receiving? so I know if it can, in theory, read the light touch and not only the heavy, sandpaper-your-fingertips-off touch? is there some manual setting that the system might not be setting correctly and which I could change from the terminal?

• HP Probook touchpad

  - by ScienceSE

  I wrote about this problem some weeks ago, but now the question is: "Why is touchpad works not so good as in windows". I tried some "experiments": When I use windows and if I accidentally touched touchpad - cursor isn't moving, also no clicks occurring. So in windows working with touchpad is quite normal, but in Ubuntu ?f I accidentally touch the touchpad even with my wrist - cursor is moving etc. In Windows, the cursor moves only when I touch it with finger. And... If, for example, I hold one finger on touchpad and simultaneously move the second finger on the touchpad - the cursor doesn't move, however in ubuntu he does. He's "super sensetive" in ubuntu or what? Also I tried to apply the option in "Mouse and touchpad", which called "Disable touchpad when typing", but nevertheless he isn't disabling when i'm typing... Note: this option is circled in red frame, i dont know is it a good "sign" ) What can I do to fix the problem?

  I am a bit unsure where to post this, but i guess it should be here, as it has to do with rendering in a browser. We have a sencha touch 1.1 application running in Google Chrome. On mij own computer (ubuntu) there are no problems. On the touch screen attached to a computer running debian-OS, transparency is shown as semi-transparent. It happens on sliders. Sliders have a button on them. This button is rendered bij sencha with CSS. It is NOT an image. Anyone has any idea how to get it 'nice' on debian too

• Drivers are not detecting on my Dell inspiron 5420 (14R 3rd generation)

  - by Ranjan Mallik

  I'm using DELL inspiron 5420 (14R 3rd generation), and tried to install ubuntu 10.10, 11.10, 12.04, 12.04.1 but each and every time it doesn't support any of my driver such as network card, wireless driver, video driver and as well as audio and touch-pad driver. audio, video and touch-pad works with their basic functionality but don't work with their full functionality. I'm a new user of ubuntu, and willing to use it permanently. In this condition I tried some solutions from the web but didn't get out from this problem. For this I'm knocking to you, If you give me the proper solution for getting out of this problem, I'll be very helpful to you all. Thanks

• Concurrent Affairs

  - by Tony Davis

  I once wrote an editorial, multi-core mania, on the conundrum of ever-increasing numbers of processor cores, but without the concurrent programming techniques to get anywhere near exploiting their performance potential. I came to the.controversial.conclusion that, while the problem loomed for all procedural languages, it was not a big issue for the vast majority of programmers. Two years later, I still think most programmers don't concern themselves overly with this issue, but I do think that's a bigger problem than I originally implied. Firstly, is the performance boost from writing code that can fully exploit all available cores worth the cost of the additional programming complexity? Right now, with quad-core processors that, at best, can make our programs four times faster, the answer is still no for many applications. But what happens in a few years, as the number of cores grows to 100 or even 1000? At this point, it becomes very hard to ignore the potential gains from exploiting concurrency. Possibly, I was optimistic to assume that, by the time we have 100-core processors, and most applications really needed to exploit them, some technology would be around to allow us to do so with relative ease. The ideal solution would be one that allows programmers to forget about the problem, in much the same way that garbage collection removed the need to worry too much about memory allocation. From all I can find on the topic, though, there is only a remote likelihood that we'll ever have a compiler that takes a program written in a single-threaded style and "auto-magically" converts it into an efficient, correct, multi-threaded program. At the same time, it seems clear that what is currently the most common solution, multi-threaded programming with shared memory, is unsustainable. As soon as a piece of state can be changed by a different thread of execution, the potential number of execution paths through your program grows exponentially with the number of threads. If you have two threads, each executing n instructions, then there are 2^n possible "interleavings" of those instructions. Of course, many of those interleavings will have identical behavior, but several won't. Not only does this make understanding how a program works an order of magnitude harder, but it will also result in irreproducible, non-deterministic, bugs. And of course, the problem will be many times worse when you have a hundred or a thousand threads. So what is the answer? All of the possible alternatives require a change in the way we write programs and, currently, seem to be plagued by performance issues. Software transactional memory (STM) applies the ideas of database transactions, and optimistic concurrency control, to memory. However, working out how to break down your program into sufficiently small transactions, so as to avoid contention issues, isn't easy. Another approach is concurrency with actors, where instead of having threads share memory, each thread runs in complete isolation, and communicates with others by passing messages. It simplifies concurrent programs but still has performance issues, if the threads need to operate on the same large piece of data. There are doubtless other possible solutions that I haven't mentioned, and I would love to know to what extent you, as a developer, are considering the problem of multi-core concurrency, what solution you currently favor, and why. Cheers, Tony.
