  • VirtualBox: Host OS processor is spiked while guest OS virtual processor is idle?

    - by Greg Mattes
    I'm running Windows XP 32-bit on Windows Vista 64-bit with VirtualBox 3.0.6. Whenever I run the XP VM, Vista (host) reports 100% cpu utilization even though XP (guest) reports between 1-5% cpu utilization. The host box has 2 GB of physical RAM. The guest/vm is configured with 512 MB. The host box has a 64-bit AMD processor. No apps (other than VirtualBox) are running on either host, they're just idling. Any guesses as to why the host processor is spiked? I've enabled various advanced features for the XP guest in the hopes of having better performance: Settings → System → Motherboard: Enable IO APIC Settings → System → Processor: Enable PAE/NX Settings → System → Acceleration: Enable VT-x/AMD-V and Enable Nesting Paging

  • PC boots on then off & 30 sec. later on again, it wiil shut off on itself mostly in idle or just unexpecticly

    - by Jody
    This problem started w/ my sons desktop, it would just shut off after a bit of work or stay on for a long time & to get it to unfreeze is to cold boot it, i put a new HDD in & I still have the same issue, RAM is good power supply fan is moving quite as well as all the rest of the fans it has stayed fairly dust free, i'm at a loss ,I have defaulted all the factory settings changed battery & ungraded to a new OS. I still have the same problem. the power light stays on after it has shut down & when upon starting it goes straight to safe mode option page, I start in last good config. reboots again takes 30 sec. to boot & will work again for a while, the only other thing I haven't tried was a graphic card replace, i'm onboard video now & have been.

  • Why is idle windows VM using so much CPU?

    - by Jeff Shattock
    I have 2 VMs running as guests on a KVM virtualization platform running on Ubuntu 10.04. One VM is an Ubuntu 10.04 system, the other is a Windows 7 system. When both machines are completely logged out, the Linux machine uses 1% CPU, the Windows one 45-50%, according to top. The graphs in virt-manager seem to back this up. Theres nothing installed on the Win7 image that would be running in the background; its as fresh as can be. Why is the Windows VM using so much more than the Linux VM, when both are logged out and idling?

  • How do I lower idle cpu usage in ubuntu linux? Gnome or KDE Variants

    - by Jasen
    My question comes from a kde desktop currently, but it also happens with the gnome instance. When just sitting there, with only the cpu monitor widget running. no open windows, no background processes other than the desktop, my cpu is at ~20%. I wanna know how to fix this, and possibly get better performance out of it. When running my windows side, the cpu will sit at zero, and i generally load new programs about 400ms faster. With windows 7 being as slow as it is, this is not acceptable. and the widget is only set to check every 500ms, so im almost completely sure its not the widget. My system is a Gateway nv 53 amd 2.0 ghz turion with 4 gb of installed ram, and 500 gb hd. both linux and windows are 64 bit. average ram use on either system is about 1.4 gb for just the os

  • VMware guest pauses when the host is idle - how do I keep it running?

    - by EMP
    I'm running VMWare Worstation 7 with Windows 7 x64 as guest, Windows XP x64 as host. Inside the guest I run a long-running console application, which prints out progress messages with timestamps on them. Sometimes I leave it running for several hours while I lock the host OS and don't touch the computer at all. When I come back I find that some time after I left it seems to have paused and automatically resumed: the console app hasn't made much progress and there's a large time gap in its progress messages. There's nothing relevant in the host event log, but in the guest Application event log I can see these messages around the time I left: A request to disable the Desktop Window Manager was made by process (VMware Tools Service) The Desktop Window Manager was unable to start because composition was disabled by a running application And later, around the time I returned, this shows up in the System log: The system time has changed to ?2012?-?01?-?12T06:36:46.921000000Z from ?2012?-?01?-?12T03:18:19.953079000Z. That seems to support my theory that it's VMware doing something and not Windows itself. The question is: how do I stop it doing that? I want my application to continue running. By the way, the power options are set to never sleep in both guest and host.

  • What's the proper way to change a process' scheduling policy to IDLE?

    - by ??O?????
    Hello. I have a long running process on a server running Ubuntu Server 9.10. I would like to make it run under the SCHED_IDLE policy using the chrt command. However, after reading the man page, I can't manage to understand the proper way to issue the command for a running process. I've tried unsuccessfully: # chrt -i -p 688 pid 688's current scheduling policy: SCHED_OTHER pid 688's current scheduling priority: 0 # chrt -p -i 688 pid 688's current scheduling policy: SCHED_OTHER pid 688's current scheduling priority: 0 # chrt -p 688 -i chrt: failed to set pid 0's policy: Invalid argument I'll keep trying, but do you know how to do what I want?

  • Play! Framework 1.2.4 --- C3P0 settings to avoid Communications link failure do to idle time

    - by HelpMeStackOverflowMyOnlyHope
    I'm trying to customize my C3P0 settings to avoid the error shown at the bottom of this post. It was suggested at this url --- http://make-it-open.blogspot.com/2008/12/sql-error-0-sqlstate-08s01.html --- to adjust the settings as follows: In hibernate.cfg.xml, write <property name="c3p0.min_size">5</property> <property name="c3p0.max_size">20</property> <property name="c3p0.timeout">1800</property> <property name="c3p0.max_statements">50</property> Then create "c3p0.properties" in your root classpath folder and write c3p0.testConnectionOnCheckout=true c3p0.acquireRetryDelay=1000 c3p0.acquireRetryAttempts=1 I've tried to make those adjustments following the direction of the Play! Framework documentation, where they say use "db.pool..." as follows: db.pool.timeout=1800 db.pool.maxSize=15 db.pool.minSize=5 db.pool.initialSize=5 db.pool.acquireRetryAttempts=1 db.pool.preferredTestQuery=SELECT 1 db.pool.testConnectionOnCheckout=true db.pool.acquireRetryDelay=1000 db.pool.maxStatements=50 Are those settings not going to work? Should I be trying to set them in a different way? With those settings I still get the error shown below, that is due to to long of a idle time.

  • How do you model roles / relationships with Domain Driven Design in mind?

    - by kitsune
    If I have three entities, Project, ProjectRole and Person, where a Person can be a member of different Projects and be in different Project Roles (such as "Project Lead", or "Project Member") - how would you model such a relationship? In the database, I currently have the following tablers: Project, Person, ProjectRole Project_Person with PersonId & ProjectId as PK and a ProjectRoleId as a FK Relationship. I'm really at a loss here since all domain models I come up with seem to break some "DDD" rule. Are there any 'standards' for this problem? I had a look at a Streamlined Object Modeling and there is an example what a Project and ProjectMember would look like, but AddProjectMember() in Project would call ProjectMember.AddProject(). So Project has a List of ProjectMembers, and each ProjectMember in return has a reference to the Project. Looks a bit convoluted to me. update After reading more about this subject, I will try the following: There are distinct roles, or better, model relationships, that are of a certain role type within my domain. For instance, ProjectMember is a distinct role that tells us something about the relationship a Person plays within a Project. It contains a ProjectMembershipType that tells us more about the Role it will play. I do know for certain that persons will have to play roles inside a project, so I will model that relationship. ProjectMembershipTypes can be created and modified. These can be "Project Leader", "Developer", "External Adviser", or something different. A person can have many roles inside a project, and these roles can start and end at a certain date. Such relationships are modeled by the class ProjectMember. public class ProjectMember : IRole { public virtual int ProjectMemberId { get; set; } public virtual ProjectMembershipType ProjectMembershipType { get; set; } public virtual Person Person { get; set; } public virtual Project Project { get; set; } public virtual DateTime From { get; set; } public virtual DateTime Thru { get; set; } // etc... } ProjectMembershipType: ie. "Project Manager", "Developer", "Adviser" public class ProjectMembershipType : IRoleType { public virtual int ProjectMembershipTypeId { get; set; } public virtual string Name { get; set; } public virtual string Description { get; set; } // etc... }

  • How do I develop browser plugins with cross-platform and cross-browser compatibility in mind?

    - by Schnapple
    My company currently has a product which relies on a custom, in-house ActiveX control. The technology it employs (TWAIN) is itself cross-platform by design, but our solution is obviously limited to Internet Explorer on Windows. Long term we would like to become cross-browser and cross-platform (i.e., support other browsers on Windows, support the Macintosh or Linux). Obviously if we wanted to support Firefox on Windows I would need to write a plugin for it. But if we wanted to support the Macintosh, how do I attack that? Is it possible to compile a version of the Firefox plugin that runs on the Mac? Would I be remiss to not also support Safari on the Mac? Are there any plugins which are cross-browser on a platform? (i.e., can any browsers run plugins for other browsers) Since TWAIN is so low-level to the operating system, I do not think Java would be a solution in any capacity, but I could be wrong. What do people generally do when they want to support multiple platforms with a process that will need to be cross-platform and cross-browser compatible?

  • PHP, We have sessions, and cookies....I love cookies, but they are blowing my mind right now.

    - by Matt
    I am not sure how to go about accessing the variable I need to set on a cookie... I was thinking about using the $_POST global but I dont know how based on my design if it will work. I am using a master page type design seperating index.php from my function includes and database information and individual pages (that will be returned to an include in index.php based on a $_GET) Okay so back to my question. What is the most efficient way to set a cookie on a design that has a main page that everything will branch from. How would I pull the value. Is $_POST a good enough way to go about it? Also...by saying it must be the first thing sent...does that mean I cannot run any serverside scripts before that? I could definately utilize a login query I think but I dont want to write code just to be dissapointed based on my lack of time and knowledge. I did search for answers...I know this most likely feels like a generic question that could be answered in a difference place...but I know I will get an accurate and professional answer here...so I dont want to bet on the half answers I found otherwise. Of course I will sanitize everything and not store any sensitive information (passwords,address,phone,or anything really for that matter besides some kind of session ID and the username) If this is confusing I am sorry but I am on a gov computer...and they lock these tighter than ft knox...so getting my code on here will be a chore until I get back to my room. Thanks, Matt

  • Would someone mind giving suggestions for this new assembly language?

    - by Noctis Skytower
    Greetings! Last semester in college, my teacher in the Computer Languages class taught us the esoteric language named Whitespace. In the interest of learning the language better with a very busy schedule (midterms), I wrote an interpreter and assembler in Python. An assembly language was designed to facilitate writing programs easily, and a sample program was written with the given assembly mnemonics. Now that it is summer, a new project has begun with the objective being to rewrite the interpreter and assembler for Whitespace 0.3, with further developments coming afterwards. Since there is so much extra time than before to work on its design, you are presented here with an outline that provides a revised set of mnemonics for the assembly language. This post is marked as a wiki for their discussion. Have you ever had any experience with assembly languages in the past? Were there some instructions that you thought should have been renamed to something different? Did you find yourself thinking outside the box and with a different paradigm than in which the mnemonics were named? If you can answer yes to any of those questions, you are most welcome here. Subjective answers are appreciated! hold N Push the number onto the stack copy Duplicate the top item on the stack copy N Copy the nth item on the stack (given by the argument) onto the top of the stack swap Swap the top two items on the stack drop Discard the top item on the stack drop N Slide n items off the stack, keeping the top item add Addition sub Subtraction mul Multiplication div Integer Division mod Modulo save Store load Retrieve L: Mark a location in the program call L Call a subroutine goto L Jump unconditionally to a label if=0 L Jump to a label if the top of the stack is zero if<0 L Jump to a label if the top of the stack is negative return End a subroutine and transfer control back to the caller exit End the program print chr Output the character at the top of the stack print int Output the number at the top of the stack input chr Read a character and place it in the location given by the top of the stack input int Read a number and place it in the location given by the top of the stack Question: How would you redesign, rewrite, or rename the previous mnemonics and for what reasons?

  • How do I design a Wizard-based system with SoC in mind?

    - by Erik Forbes
    I'm building a Windows Forms system (in C# if it matters to anyone) that provides an application automation service. As this application is targeted at users who are not computer savvy, I've decided to break up the functions of the application into various tasks, and provide these tasks via a wizard UI. I'd like to avoid coupling the views and view engine (from which the Wizard will be built) to the automation engine. The problem I'm having is that the automation engine, which runs on a separate thread while it does its thing, needs to report status information back to the user, as well as listen for cancel or pause events from the user. Since I don't want the view engine or the automation engine to rely on each other, I'm having a hard time figuring out how to provide for this information conduit. Any insights into this issue I'm having would be greatly appreciated. I've been wracking my brain for a couple weeks now on this point, and I really don't want to give up and just couple everything together. If anyone needs additional details to help come up with some sort of idea please let me know and I'll be happy to provide them.

  • Agile methodologies. Is it a by-product of mind control techniques as NLP / Scientology?

    - by Bobb
    The more I read about contemporary methods combinging scrum, tdd and xp, the more I feel like I already seen the methods. I am not arguing that agile approach is much more progressive than older rigid structures like waterfall, what I am saying is that it seems to me that agile methodologies are ideal to be used as a nest for a brainwashing business. I read few articles which kept referring to authors which I checked afterwards and they call themselves - coaches, trainers (usual thing when NLP specialists are involved) with no apparent software development history. Also I met a guy who is a scrum faciltator (term widly used in relation to scientology) in a high profile company. I talked to him less than 5 min but I got complete feeling that he is either on drugs or he has been programmed by a powerful NLP specialist. The way to talk and his body movements witnessed he is not an average normal person (in terms of normal distribution :))... Please dont get me wrong. I am not a fun of conspiracy theories. But I had an experience with a member of church of scientology tried to invade a commercial firm and actually went half way through to very top in just 3 weeks. I saw his work. For now I have complete impression is that psycho manipulators are now invading IT industry through the convenient door of agile techniques. Anyone has the same feeling/thoughts?

  • How to syncronize two animations without delays

    - by GeKi
    I have one character idle animation running inside a game in a loop, over and over again. A a certain time I trigger another animation to be played, for the same character. The second animation won't play immediately, as will be a discontinuity in my character animation. First I wait for the idle animation to finish and then I play my second animation. Now I have a smooth, continuous animation, BUT I have introduced a delay between my action and character animation. If I play the second animation right away as it is triggered, the character animation won't be continuous and smooth. I was thinking on breaking the idle animation in small pieces and also to have the same number of second action animations to match the last frame of the idle pieces. This won't solve the delay completely, only will minimize it a bit. So it's a magic formula of how can I get rid of this delay? Thanks.

  • SSMS Tools Pack 2.0 is out! With huge productivity booster features that will blow your mind and ease your job even more.

    - by Mladen Prajdic
    What better way to end the summer and start those productive autumn days ahead than with a fresh new version of the SSMS Tools Pack. This is a big release with two new features that are huge productivity boosters. First new feature are Tab Sessions. Every SQL tab you open is saved every N (default 2) minutes and is stored in a session. This works similar to internet browser sessions. Once you reopen SSMS you can restores your last session with a click of a button. You even get every window connected to the server it was previously connected to. The Tab History Window looks like this:   The second feature is Execution Plan Analyzer. It is designed to quickly help you find costliest operators by a number of properties. If that's not enough you can easily search through the whole execution plan for whatever you like. And to top it off you can auto analyze the execution plan. The analysis reports various problems the execution plan has and suggests a most common solution. The ultimate purpose of the Execution Plan Analyzer is to make your troubleshooting quicker and easier. It uses a simple user interface that is easy to navigate and is built directly into the execution plan itself. The execution plan analyzer looks like this:   Smaller fixes include a completely redesigned SQL History Search window and various other bug fixes. You can download the new version 2.0 at the Download page. For more detailed feature descriptions go to the main Features Page. Enjoy it!

  • How do I subvert computer idle detection on Windows?

    In order to detect user absence GetLastInputInfo() can be used. I want to make GetLastInputInfo() return that I've just used keyboard/mouse all the time - as I've been actively using the computer so that whoever relies on GetLastInputInfo() thinks I'm actively using the computer. Can I use any Windows API functions to achieve that?

  • How do I wait until a console application is idle?

    - by Anthony Mastrean
    I have a console application that starts up, hosts a bunch of services (long-running startup), and then waits for clients to call into it. I have integration tests that start this console application and make "client" calls. How do I wait for the console application to complete its startup before making the client calls? I want to avoid doing Thread.Sleep(int) because that's dependent on the startup time (which may change) and I waste time if the startup is faster. Process.WaitForInputIdle works only on applications with a UI (and I confirmed that it does throw an exception in this case). I'm open to awkward solutions like, have the console application write a temp file when it's ready.
