  • How to avoid oscillation by async event based systems?

    - by inf3rno
    Imagine a system where there are data sources which need to be kept in sync. A simple example is model - view data binding by MVC. Now I intend to describe these kind of systems with data sources and hubs. Data sources are publishing and subscribing for events and hubs are relaying events to data sources. By handling an event a data source will change it state described in the event. By publishing an event the data source puts its current state to the event, so other data sources can use that information to change their state accordingly. The only problem with this system, that events can be reflected from the hub or from the other data sources, and that can put the system into an infinite oscillation (by async or infinite loop by sync). For example A -- data source B -- data source H -- hub A -> H -> A -- reflection from the hub A -> H -> B -> H -> A -- reflection from another data source By sync it is relatively easy to solve this issue. You can compare the current state with the event, and if they are equal, you don't change the state and raise the same event again. By async I could not find a solution yet. The state comparison does not work by async event handling because there is eventual consistency, and new events can be published in an inconsistent state causing the same oscillation. For example: A(*->x) -> H -> B(y->x) -- can go parallel with B(*->y) -> H -> A(x->y) -- so first A changes to x state while B changes to y state -- then B changes to x state while A changes to y state -- and so on for eternity... What do you think is there an algorithm to solve this problem? If there is a solution, is it possible to extend it to prevent oscillation caused by multiple hubs, multiple different events, etc... ? update: I don't think I can make this work without a lot of effort. I think this problem is just the same as we have by syncing multiple databases in a distributed system. So I think what I really need is constraints if I want to prevent this problem in an automatic way. What constraints do you suggest?

  • Tricky situation with EF and Include while projecting (Select / SelectMany)

    - by Vincent Grondin
    Originally posted on: http://geekswithblogs.net/vincentgrondin/archive/2014/06/07/tricky-situation-with-ef-and-include-while-projecting-select.aspxHello, the other day I stumbled on a problem I had a while back with EF and Include method calls and decided this was it and I was going to blog about it…  This would sort of to pin it inside my head and maybe help others too !  So I was using DBContext and wanted to query a DBSet and include some of it’s associations and in the end, do a projection to get a list of Ids…   At first it seems easy…  Query your DBSet, call Include right afterward, then code the rest of your statement with the appropriate where clause and then, do the projection…   Well it wasn’t that easy as my query required I code my where on some entities a few degree further in the association chain and most of these links where “Many”…  I had to do my projection right away with the SelectMany method.  So I did my stuff and tested the query….  no association where loaded…  My Include statement was simply ignored !  Then I remembered this behavior and how to get it to work…  You need to move the Include AFTER your first projection (Select or SelectMany).  So my sequence became:   Query the DBSet, do the projection with SelectMany, Include the associations, code the where clause and do the final projection…. but it wouldn’t compile…   It kept saying that it could not find an “Include” method on an IQueryable… which is perfectly true!  I knew this should work so I went to the definition of the DBset and saw it inherited DBQuery and sure enough the include method was there…  So I had to cast my statement from start until the end of the first projection in a DBQuery then do the Includes and then the rest of my query….   Bottom line is, whenever your Include statement seem to be ignored, then maybe you will need to move them further down in your query and cast your statement in whatever class gives you access to the Include…   Happy coding all !

  • Why do most programming languages only support returning a single value from a function?

    - by M4N
    Is there a reason or an explanation why functions in most(?) programming languages are designed to support any number of input parameters but only one return value? In most languages, it is possible to "work around" that limitation, e.g. by using out-parameters, returning pointers or by defining/returning structs/classes. But it seems strange, that programming languages were not designed to support multiple return values in a more "natural" way.

  • ps3 controller failed to pair

    I'm trying to pair my ps3 controller with trusty.

  • in iOS7 how do you stop the First viewcontroller autorotating?

    - by uaka
    I have an app that just needs one screen to autorotate, the first and last screens should be portrait. I can get the last screen to stop rotating using: -(NSUInteger)supportedInterfaceOrientations { return UIInterfaceOrientationMaskPortrait; } But this does not work on the first screen, I am using a storyboard with a UINavigationController (I'm thinking that may have something to do with it?) Any help would be gratefully received. Thanks

  • A colourblind member of our team...

    - by dbramhall
    We rely a lot on colour within our code within our team to outline features that need working on and what needs attention, we we think can be improved (we mainly colour the line of the code) for the application we're developing, however we have a close friend that is colourblind and he wants to join our team despite our heavily reliance on colour. Do you have any other recommendations as to how a team can highlight what needs work on without the use of colour - our team is about 25 people that are all accustom to the line colouring system and we have found it be most efficient.

  • What are the statements in XNA?

    - by Katie Hajduk
    A hypothetical game called “AlienShooter” needs to be able to work on Windows and on the Xbox. In the Windows version, the keyboard will handle firing at alien spaceships, and this functionality is contained within a method called “KeyboardSupport()”. In the Xbox version of the game, the gamepad will be used for shooting, and this functionality is contained within a method called “GamepadSupport()”. Write the statement(s) that must be added so that the appropriate code is used in the each version of the game.

  • How do you keep track of the authors of code?

    - by garbagecollector
    This is something I was never taught. I have seen alot of different types of authoring styles. I code primarily in Java and Python. I was wondering if there was a standard authoring style or if everything is freestyle. Also if you answer would you mind attaching the style you use to author files that your create at home or at work. I usually just go @author garbagecollector @company garbage inc.

  • How to have an Arduino wait until it receives data over serial?

    - by SonicDH
    So I've wired up a little robot with a sound shield and some sensors. I'm trying to write a sketch that will let check the sensors. What I'd like for it to do is print out a little menu over serial, wait until the user sends a selection, jump to the function that matches their selection, then (once the function is done) jump back and print the menu again. Here's what I've written, but I'm not a that good of a coder, so it doesn't work. Where am I going wrong? #include <Servo.h> Servo steering; Servo throttle; int pos = 0; int val = 0; void setup(){   Serial.begin(9600);   throttle.write(90);   steering.write(90);   pinMode(A0, INPUT);   pinMode(7, INPUT);   char ch = 0; } void loop(){   Serial.println("Menu");   Serial.println("--------------------");   Serial.println("1. Motion Readout");   Serial.println("2. Distance Readout");   Serial.println("3. SD Directory Listing");   Serial.println("4. Sound Test");   Serial.println("5. Car Test");   Serial.println("--------------------");   Serial.println("Type the number and press enter");   while(char ch = 0){   ch = Serial.read();}   char ch;   switch(ch)   {     case '1':     motion();   }    ch = 0; } //menu over, lets get to work. void motion(){   Serial.println("Haha, it works!"); } I'm pretty sure a While loop is the right thing to do, but I'm probably implementing it wrong. Can anyone shed some light on this?

  • Best virtualization solution for running Windows 7 as a guest?

    - by gkt.pro
    I depend upon Ubuntu for most of my work but I still need Windows 7 for some applications such as Office 2010 Casual Gaming Adobe CS4 and other windows softwares that are not available on Ubuntu yet. I checked Wine but as of now it provides no support for Office 2010 and most of my games and softwares. So, I decided to go for Virtualizing Windows 7 inside Ubuntu, but I am confused about which virtualization software should I use on Ubuntu for virtualization.

  • BI Beginner: Why to Use Excel 2013 Now

    - by John Paul Cook
    Most corporations and many individuals are slow to adopt new versions of Microsoft Office, particularly if the upgrade to the previous version was very recent. Excel 2013 is a special case and offers significant productivity enhancements. If you do business intelligence work or otherwise make your living with Excel, adding (notice I didn’t say upgrading to) Excel 2013 now makes a lot of sense. The Power View feature in Excel 2013 is a completely sufficient reason to add Excel 2013. It has to be enabled,...(read more)

  • Making diff output more readable

    - by mgunes
    I'm looking for a tool that will take diff / debdiff output (and more specifically, the output of this script) and display the result of the comparison in a highly readable, graphical way. Any pointers would be appreciated. Ideally, it would be the GTK+, FOSS equivalent of MDR. Meld, Diffuse and similar software are not fit for this purpose, since they're intended to work standalone, and don't take input from stdin.

  • Ubuntu 12.4.1 failing in vm both Vbox and Vmware on new HP Envy 4t-1000

    - by Chas
    Brand new to Linux, getting frustrated trying to get an environment up with Ubuntu. My primary goal is to learn Linux and Apache/PHP development. I need to keep my Windows OS as main on my machine for work, so i'm trying to virtualize Ubuntu 12.4.1 without luck (many attempts). I have a new HP Envy 4t-1000 with 16gb ram, and 32 gb ssd caching with 500gb spindle hard drive. Graphics card is an Intel HD 3000 with AMD Radeon 7670M. With installing Ubuntu desktop in VBox, I'm getting this result: https://forums.virtualbox.org/viewtopic.php?f=6&t=51939 With VMware workstation 7 (patched), I complete the install of Ubuntu, it reboots, purple desktop briefly flashes then it drops to command line. I bought a beginning Ubuntu book, and it recommends trying to manually configure graphics if this happens. So I tried doing a safe boot holding shift - I get to the first screen (GRUB) loads fine, and I choose recovery mode. After choosing the recovery mode, I get the recovery mode options, and can arrow down to what the book suggests 'Run in fail safe graphic mode.' Once I select this option, I get a black screen with a large white dialogue box, at the top it says "The system is running in low-graphics mode. Your screen, graphics card, and input device settings could not be detected correctly. You will need to configure these yourself." Then there is an ok button way down at the bottom. When I select 'ok' I get a menu for a few options, book recommended 'reconfigure graphics.' When I try this, I get a menu of two options: 1) "Use generic (default) configuration or 2) use backup. I've tried both options several times, hitting ok just refreshes screen and nothing more. Rebooting at this point just goes back to command line as before. I don't know what to do at this point, I've spent too many hours this weekend trying in both VBox and VMware to get Ubuntu going. Isn't there like a very basic graphic display or something I can use to at least get into the desktop? I explored the GRUB some more, and tried to look at the startup and xserver logs - both are blank. No help there I guess? When I try to choose 'Edit the configuration file, then 'ok' screen just refreshes on same menu options, nothing happens. thx for any advice. I really need to focus on learning Linux, Apache and PHP, so perhaps Ubuntu just won't work on my hardware? Any other suggestions? I will need to virtualize - THANKS for any help/advice.

  • Ubuntu 12.10 not working on UX32VD after update to beta 1 [closed]

    - by bquast
    Possible Duplicate: There's an issue with an Alpha/Beta Release of Ubuntu, what should I do? In my previous question I described my problem with starting / returning from suspend using Ubuntu on the Asus UX32VD (Zenbook). This problem could be solved by using Ubuntu 12.10 (alpha), however since the upgrade to beta 1 the old problem of starting / returning from suspend has returned. I found that starting in recovery does work, but this of course does not solve the problem. Any thoughts?
