  • java threads don't see shared boolean changes

    - by andymur
    Here the code class Aux implements Runnable { private Boolean isOn = false; private String statusMessage; private final Object lock; public Aux(String message, Object lock) { this.lock = lock; this.statusMessage = message; } @Override public void run() { for (;;) { synchronized (lock) { if (isOn && "left".equals(this.statusMessage)) { isOn = false; System.out.println(statusMessage); } else if (!isOn && "right".equals(this.statusMessage)) { isOn = true; System.out.println(statusMessage); } if ("left".equals(this.statusMessage)) { System.out.println("left " + isOn); } } } } } public class Question { public static void main(String [] args) { Object lock = new Object(); new Thread(new Aux("left", lock)).start(); new Thread(new Aux("right", lock)).start(); } } In this code I expect to see: left, right, left right and so on, but when Thread with "left" message changes isOn to false, Thread with "right" message don't see it and I get ("right true" and "left false" console messages), left thread don't get isOn in true, but right Thread can't change it cause it always see old isOn value (true). When i add volatile modifier to isOn nothing changes, but if I change isOn to some class with boolean field and change this field then threads are see changes and it works fine Thanks in advance.

  • Quickest way to compute the number of shared elements between two vectors

    - by shn
    Suppose I have two vectors of the same size vector< pair<float, NodeDataID> > v1, v2; I want to compute how many elements from both v1 and v2 have the same NodeDataID. For example if v1 = {<3.7, 22>, <2.22, 64>, <1.9, 29>, <0.8, 7>}, and v2 = {<1.66, 7>, <0.03, 9>, <5.65, 64>, <4.9, 11>}, then I want to return 2 because there are two elements from v1 and v2 that share the same NodeDataIDs: 7 and 64. What is the quickest way to do that in C++ ? Just for information, note that the type NodeDataIDs is defined as I use boost as: typedef adjacency_list<setS, setS, undirectedS, NodeData, EdgeData> myGraph; typedef myGraph::vertex_descriptor NodeDataID; But it is not important since we can compare two NodeDataID using the operator == (that is, possible to do v1[i].second == v2[j].second)

  • jquery datepicker - retrieve events and show on hover in dialog - allow the a href to be clicked to access individual event entries

    - by paul724
    Please see this jsfiddle - http://jsfiddle.net/paul724/HXb6v/ What is working: The datepicker displays correctly, picks up the css for todays date and on hover. The dialog box follows the mouse On click the dialog box "stops" and displays a link What I want to achieve When a table cell is hovered over the title of the dialog box shows the date e.g "Mon 8th Oct 2012" When a table cell is hovered over the html of the dialog box shows the events for that day in list format (there is code that succesfully retrieves the first row in function getSelectedDates() ) function getSelectedDates() needs to be called in the hover event - showing multiple events for that date in the dialog box I hope that if we can display the date being hovered over in the title of the dialog then we can use the same information to retrieve the rows from the database to populate the html of the dialog for that day

  • Intellisense fails for boost::shared_ptr with Boost 1.40.0 in Visual Studio 2008

    - by Edward Loper
    I'm having trouble getting intellisense to auto-complete shared pointers for boost 1.40.0. (It works fine for Boost 1.33.1.) Here's a simple sample project file where auto-complete does not work: #include <boost/shared_ptr.hpp> struct foo { bool func() { return true; }; }; void bar() { boost::shared_ptr<foo> pfoo; pfoo.get(); // <-- intellisense does not autocomplete after "pfoo." pfoo->func(); // <-- intellisense does not autocomplete after "pfoo->" } When I right-click on shared_ptr, and do "Go to Definition," it brings be to a forward-declaration of the shared_ptr class in . It does not bring me to the actual definition, which is in However, it compiles fine, and auto-completion works fine for "boost::." Also, auto-completion works fine for boost::scoped_ptr and for boost::shared_array. Any ideas?

  • Determine target architecture of binary file in Linux (library or executable)

    - by Fernando Miguélez
    We have an issue related to a Java application running under a (rather old) FC3 on a Advantech POS board with a Via C3 processor. The java application has several compiled shared libs that are accessed via JNI. Via C3 processor is suppossed to be i686 compatible. Some time ago after installing Ubuntu 6.10 on a MiniItx board with the same processor I found out that the previous statement is not 100% true. The Ubuntu kernel hanged on startup due to the lack of some specific and optional instructions of the i686 set in the C3 processor. These instructions missing in C3 implementation of i686 set are used by default by GCC compiler when using i686 optimizations. The solution in this case was to go with a i386 compiled version of Ubuntu distribution. The base problem with the Java application is that the FC3 distribution was installed on the HD by cloning from an image of the HD of another PC, this time an Intel P4. Afterwards the distribution needed some hacking to have it running such as replacing some packages (such as the kernel one) with the i383 compiled version. The problem is that after working for a while the system completely hangs without a trace. I am afraid that some i686 code is left somewhere in the system and could be executed randomly at any time (for example after recovering from suspend mode or something like that). My question is: Is there any tool or way to find out at what specific architecture is an binary file (executable or library) aimed provided that "file" does not give so much information?

  • Boost shared_ptr use_count function

    - by photo_tom
    My application problem is the following - I have a large structure foo. Because these are large and for memory management reasons, we do not wish to delete them when processing on the data is complete. We are storing them in std::vector<boost::shared_ptr<foo>>. My question is related to knowing when all processing is complete. First decision is that we do not want any of the other application code to mark a complete flag in the structure because there are multiple execution paths in the program and we cannot predict which one is the last. So in our implementation, once processing is complete, we delete all copies of boost::shared_ptr<foo>> except for the one in the vector. This will drop the reference counter in the shared_ptr to 1. Is it practical to use shared_ptr.use_count() to see if it is equal to 1 to know when all other parts of my app are done with the data. One additional reason I'm asking the question is that the boost documentation on the shared pointer shared_ptr recommends not using "use_count" for production code.

  • Can’t use Sub Reports and Shared Datasets in BIDS - Data Retrieval failed for the subreport '###', located at ### Please check the log files

    - by simonsabin
    SQL Server 2008 R2 brings us a great new feature of shared data sets. This allows datasets used by parameters and multiple reports to be defined in one place and used in multiple reports. I’ve been developing a report for SQLBits that required use of sub reports. They all use a shared data set for the agenda items. Initially I was developing in report builder but have now gone back to BIDS. In doing this however all the reports bust reporting the following error Data Retrieval failed for the subreport...(read more)

  • How would you advocate not using a shared spreadsheet to track bugs / issues ?

    - by Sylvain Defresne
    In our company, the developers want to use a proper bug tracking tool to manager issues in our application. The management however insists on using a shared spreadsheet (formeerly a shared excel file, now a spreadsheet on a web base solution allowing concurrent access). Their argument is that the spreadsheet allow them to have a more highlevel view of the state of the project as they can see how many bugs are open with a quick glance. This also allow them to see who is working on each bug, and get estimation of the time required to close them all (as developer are required to fill time estimation of the bug they are working on). As you can understand, this is not really practical to use for the developers (bug tracking software were invented for a reason). So how can I advocate bug tracking software to ease the work of the developer ? As a bonus, which software would you recommend that would allow the management to be able to get their feedbacks (number of bugs opens, who is working on them, time estimation) with a high level view ?

  • When to use shared libraries for a web framework?

    - by CamelBlues
    tl;dr: I've found myself hosting a bunch of sites running on the same web framework (symfony 1.4). Would it be helpful if I moved all of the shared library code into the same directory and shared it across the sites? more I see some advantages to this: Each site takes up less disk space Library updates (an unlikely scenario) can take place across all sites I also see some disadvantages, mostly in terms of a single point of failure and the inability to have sites using different versions of the framework. My real concern, though, is performance. I hypothesize that I will see a performance increase, since the PHP code will already be cached for all sites when they call the framework. Is this a correct hypothesis?

  • Need to set up shared storage for Guest virtual machines that are running on a Xen host

    - by Sajith
    My environment: I am doing these things at home with the purpose of learning about virtualization techniques. My machine have quad core processor that supports Intel-VT and 8GB RAM. XEN is the virtualization platform. In short, all domUs are LVM based. Mainly I have two questions; I need to have shared storage for these VMs. Something like NFS / NAS / iSCSI etc. However, I don't know which one is the best solution. Therefore, can someone tell me which suits best? Please note that, this shared storage need to be accessed by the other physical machines in the network. How to implement the selected solution for question #1? Any tutorials / guidelines / ebooks will be a great help and highly appreciated. Thank you in advance :)

  • How to automatically mount a Windows shared folder on every boot up?

    - by Zabba
    I am able to access Windows' shared folder from Ubuntu 10.10 Nautilus like so: Type into the Location Bar : smb://box/projects Now, I can see the folder in Nautilus, create/read files in it. Also, on desktop I get a folder called "projects on box". But, that folder on the desktop goes away when I reboot. So, I thought that I can automount the Windows' shared projects folder by adding this to my fstab: //box/Projects /home/base/Projects smbfs rw,user,username=jack,password=www222,fmask=666,dmask=777 0 0 (base is my user name on Ubuntu) Now, I get a folder called "Projects" in my home folder after boot up, but it is empty (cannot see the same files that I can see in Nautilus). What's am I doing wrong? Some more detail: This is what I see of the Projects folder when I do ls -l in my home folder: ... drwxr-xr-x 2 root root 4096 2011-01-01 10:22 Projects drwxr-xr-x 2 base base 4096 2011-01-01 09:06 Public ... Note the two "roots". Is that somehow the problem?

    I want to permanently mount a few Windows shared folders. I googled that topic and found a lot of good answers, but with all the solutions I have a little problem: I believe I can't properly give an address of shared folder. I can find it following way: "Network" - "Windows Network" - "WORKGROUP_name" - "Computer_name" - and there is some folder i would like to mount. How can I write the path to the folders in terminal? UPD i can access needed folder throw address in location bar smb://server/ro/, but i try mount it by editing /etc/fstab file (using guide https://wiki.ubuntu.com/MountWindowsSharesPermanently) i get error mount error: could not resolve address for server: Unknown error PS in /etc/fstab : //SERVER/RO /media/server cifs username=user,password=pwd, uid=1000,iocharset=utf8 0 0

  • Can I mix static and shared-object libraries when linking?

    - by SiegeX
    I have a C project that produces ten executables, all of which I would like to be statically linked. The problem I am facing is that one of these executables uses a 3rd-party library of which only the shared-object version is available. If I pass the -static flag to gcc, ld will error saying it can't find the library in question (I presume it's looking for the .a version) and the executable will not be built. Ideally, I would like to be able to tell 'ld' to statically link as much as it can and fail over to the shared object library if a static library cannot be found. In the interium I tried something like gcc -static -lib1 -lib2 -shared -lib3rdparty foo.c -o foo.exe in hopes that 'ld' would statically link in lib1 and lib2 but only have a run-time dependence on lib3rdparty. Unfortunatly, this did not work as I intended; instead the -shared flag overwrote the -static flag and everything was compiled as shared-objects. Is statically linking an all-or-nothing deal, or is there some way I can mix and match?

    I have 3 xsd files: a.xsd b.xsd shared.xsd shared.xsd is imported to both a.xsd and b.xsd using <xs:import schemaLocation="shared.xsd"/> shared.xsd defines <xs:element name="item"> <xs:complexType> .... If I generate java code using xjc a.xsd and b.xsd is generated into different packages and in each package a separate java class is generated for item. How would it be possible to have a single shared class for item and make a and b use it?

  • Advanced Linux file permission question (ownership change during write operation)

    - by Kent
    By default the umask is 0022: usera@cmp$ touch somefile; ls -l total 0 -rw-r--r-- 1 usera usera 0 2009-09-22 22:30 somefile The directory /home/shared/ is meant for shared files and should be owned by root and the shared group. Files created here by usern (any user) are automatically owned by the shared group. There is a cron-job taking care of changing owning user and owning group (of any moved files) once per day: usera@cmp$ cat /etc/cron.daily/sharedscript #!/bin/bash chown -R root:shared /home/shared/ chmod -R 770 /home/shared/ I was writing a really large file to the shared directory. It had me (usera) as owning user and the shared group as group owner. During the write operation the cron job was run, and I still had no problem completing the write process. You see. I thought this would happen: I am writing the file. The file permissions and ownership data for the file looks like this: -rw-r--r-- usera shared The cron job kicks in! The chown line is processed and now the file is owned by the root user and the shared group. As the owning group only has read access to the file I get a file write error! Boom! End of story. Why did the operation succeed? A link to some kind of reference documentation to back up the reason would be very welcome (as I could use it to study more details).

  • JPA Entity (in multiple persistence-unit) in OSGi (Spring DM) Environnement is confusing me.

    - by Vincent Demeester
    Hi, I'm a bit confused about a strange behavior of my JPA's related objects. I have three bundle : The User bundle does contain some user-related objects, but mainly the User object. The Energy bundle does contain some energy-related objects, and particularly a ConsumptionTerminal which contains a List of User. The Index bundle does contain an Index object that has no dependency at all. My OSGi environment is the following : A DataSource bundle that provide 2 services : dataSource and jpaVendorAdapter. The three bundles. They consume dataSource and jpaVendorAdapter. Their module-context.xml file look like : And they all have a persistence.xml file : User <?xml version="1.0" encoding="UTF-8"?> <persistence> <persistence-unit name="securityPU" transaction-type="JTA"> <jta-data-source>java:/securityDataSourceService</jta-data-source> <class>net.nextep.amundsen.security.domain.User</class> <!-- [...] --> <exclude-unlisted-classes>true</exclude-unlisted-classes> <properties> <property name="eclipselink.logging.level" value="INFO" /> <property name="eclipselink.ddl-generation" value="create-tables" /> <property name="eclipselink.ddl-generation.output-mode" value="database" /> <property name="eclipselink.orm.throw.exceptions" value="true" /> </properties> </persistence-unit> </persistence> Energy <?xml version="1.0" encoding="UTF-8"?> <persistence> <persistence-unit name="energyPU" transaction-type="JTA"> <jta-data-source>java:/securityDataSourceService</jta-data-source> <class>net.nextep.amundsen.security.domain.User</class> <class>net.nextep.amundsen.energy.domain.User</class> <!-- [...] --> <exclude-unlisted-classes>true</exclude-unlisted-classes> <properties> <property name="eclipselink.logging.level" value="INFO" /> <property name="eclipselink.ddl-generation" value="create-tables" /> <property name="eclipselink.ddl-generation.output-mode" value="database" /> <property name="eclipselink.orm.throw.exceptions" value="true" /> </properties> </persistence-unit> </persistence> Index : This one has the most simple persistence.xml with just the Index class (no shared Class). I'm using named @PersistenceUnit annotation like @PersitenceUnit(name = 'securityPU') (for the User bundle). And finally, I'm using EclipseLink as Jpa provider and Spring DM (+ Spring DM Server in the development process) The problem is the following : When the User bundle is deployed, I'm able to persist User objects. When the User bundle and Energy bundles are both deployed, I'm not able to persist User objects (neither the Energy object). But I don't have any exception at all ! There is no problem at all with the Index bundle. The bug is dataSource independent (I tried with PostgreSQL and MySQL so far). My first conclusion was that the <class>net.nextep.amundsen.security.domain.User</class> in both persistence unit was causing the trouble. I tried without it (and hiding the User dependent object in the Energy bundle) but it failed too. I'm a bit confused about that bug. I'm also not quite sure about the transaction management in this context. I wasn't the one who designed this architecture (but I tell my intern OK without testing it.. shame on me) but if I could understand this bug and maybe fix it without rewrite the bundle (and break my intern work), I would appreciate. Am I doing something wrong ? (it's obvious, but what..) Did I miss something while reading documentation ? By the way, I'm also looking for some best practices or advices when it comes to JPA, EclipseLink (or whatever JPA Provider) and Spring DM (and OSGi in general). I found interesting slides from Mike Keith about this topic (by browsing Stackoverflow).

  • Node.js Lockstep Multiplayer Architecture

    - by Wakaka
    Background I'm using the lockstep model for a multiplayer Node.js/Socket.IO game in a client-server architecture. User input (mouse or keypress) is parsed into commands like 'attack' and 'move' on the client, which are sent to the server and scheduled to be executed on a certain tick. This is in contrast to sending state data to clients, which I don't wish to use due to bandwidth issues. Each tick, the server will send the list of commands on that tick (possibly empty) to each client. The server and all clients will then process the commands and simulate that tick in exactly the same way. With Node.js this is actually quite simple due to possibility of code sharing between server and client. I'll just put the deterministic simulator in the /shared folder which can be run by both server and client. The server simulation is required so that there is an authoritative version of the simulation which clients cannot alter. Problem Now, the game has many entity classes, like Unit, Item, Tree etc. Entities are created in the simulator. However, for each class, it has some methods that are shared and some that are client-specific. For instance, the Unit class has addHp method which is shared. It also has methods like getSprite (gets the image of the entity), isVisible (checks if unit can be seen by the client), onDeathInClient (does a bunch of stuff when it dies only on the client like adding announcements) and isMyUnit (quick function to check if the client owns the unit). Up till now, I have been piling all the client functions into the shared Unit class, and adding a this.game.isServer() check when necessary. For instance, when the unit dies, it will call if (!this.game.isServer()) { this.onDeathInClient(); }. This approach has worked pretty fine so far, in terms of functionality. But as the codebase grew bigger, this style of coding seems a little strange. Firstly, the client code is clearly not shared, and yet is placed under the /shared folder. Secondly, client-specific variables for each entity are also instantiated on the server entity (like unit.sprite) and can run into problems when the server cannot instantiate the variable (it doesn't have Image class like on browsers). So my question is, is there a better way to organize the client code, or is this a common way of doing things for lockstep multiplayer games? I can think of a possible workaround, but it does have its own problems. Possible workaround (with problems) I could use Javascript mixins that are only added when in a browser. Thus, in the /shared/unit.js file in the /shared folder, I would have this code at the end: if (typeof exports !== 'undefined') module.exports = Unit; else mixin(Unit, LocalUnit); Then I would have /client/localunit.js store an object LocalUnit of client-side methods for Unit. Now, I already have a publish-subscribe system in place for events in the simulator. To remove the this.game.isServer() checks, I could publish entity-specific events whenever I want the client to do something. For instance, I would do this.publish('Death') in /shared/unit.js and do this.subscribe('Death', this.onDeathInClient) in /client/localunit.js. But this would make the simulator's event listeners list on the server and the client different. Now if I want to clear all subscribed events only from the shared simulator, I can't. Of course, it is possible to create two event subscription systems - one client-specific and one shared - but now the publish() method would have to do if (!this.game.isServer()) { this.publishOnClient(event); }. All in all, the workaround off the top of my head seems pretty complicated for something as simple as separating the client and shared code. Thus, I wonder if there is an established and simpler method for better code organization, hopefully specific to Node.js games.

  • Virtualbox shared folder mount from fstab fails; works once bootup is complete

    - by Ben
    I've got Ubuntu 13.10 installed in Virtualbox 4.3. The host machine is Windows. I have a couple of Virtualbox shared folders being mounted by /etc/fstab. Until recently this setup worked just fine, but after upgrading from Ubuntu 13.04 and Virtualbox 4.2 (at essentially the same time) the fstab mounting stopped working. I get the following error during boot: An error occurred while mounting /home/benme/Documents. keys:Press S to skip mounting or M for manual recovery Pressing M for manual recovery and then trying to mount manually also fails: root@benme-vb:~# cd /home/benme root@benme-vb:/home/benme# mount Documents /sbin/mount.vboxsf: mounting failed with the error: No such device But if I instead skip mounting during boot, wait for Unity to start and then mount manually in a shell, everything works fine: benme-vb ~ % ls Documents benme-vb ~ % sudo mount Documents [sudo] password for benme: benme-vb ~ % ls Documents # actual file list omitted Note that when I mount manually I'm letting mount take all the options from /etc/fstab, and it works. This suggests to me that it's some sort of timing issue, where Virtualbox isn't "ready" to provide the shared file mounts at the point /etc/fstab mounts are run during bootup. Here's the fstab line, just for completeness: Documents /home/benme/Documents vboxsf uid=benme,gid=benme,dmode=774,fmode=664 0 0 Is there something I can do about this from the Ubuntu side? Or does anyone happen to know more about this from the Virtualbox angle? I've found an old report on the Virtualbox bug-tracker with identical symptoms, but in that case the user had updated Virtualbox without updating their guest additions and resolving that fixed the problem; this isn't happening here, I've definitely got the 4.3 guest additions installed.

  • How do I access shared folders on Ubuntu server from Mac OS?

    - by Stephen
    I have an old dell desktop running ubuntu 11.04, I also have samba installed on it. I'm trying to access the shared folders on the Ubuntu machine from my Mac, so I go into 'Finder', click on 'Go' and 'Connect to Server'. I type in the ip address of the ubuntu machine smb://xxx.xxx.x.xx and click connect, I can then see the list of shared folders from the ubuntu machine so I know its making a connection. But when I access the 'Music' folder I get an error message stating: There was an error connecting to the server "xxx.xxx.x.xx". Check the server name or IP address, and try again. Any thoughts anyone ? EDIT I have a external hard drive attached to the server, and the folders I'm trying to access are located on that external hard drive. The location of the folder is /media/HD-CELU2/test, so I think the path from Finder should be smb://xxx.xxx.x.xx/media/HD-CELU2/test, but having tested this, I'm still not getting in. P.S. I'm using Samba as I have a Windows machine on my home network as well.

  • What is an effective way to convert a shared memory-mapped system to another data access model?

    - by Rob Jones
    I have a code base that is designed around shared memory. Each process that needs to access the memory maps it into its own address space. The data structures in the shared memory are directly accessed, that is, there is no API. For example: Assume the following: typedef struct { int x; int y; struct { int a; int b; } z; } myStruct; myStruct s; Then a process might access this structure as: myStruct *s = mapGlobalMem(); And use it as: int tmpX = s->x; The majority of the information in the global structure is configuration information that is set once and read many times. I would like to store this information in a database and develop an API to access the database. The problem is, these references are sprinkled throughout the code. I need a way to parse the code and identify global structure references that will need to be refactored. I've looked into using ANTLR to create a parser that will identify references to a small set of structures and enter them into a custom symbol table. I could then use this symbol table to identify which source files need to be refactored. It looks like a promising approach. What other approaches are there? Of course, I'm looking for a programmatic approach. There are far too many source files to examine each one visually. This is all ordinary ANSI C. Nothing else.
