  • Session state server saying extended class no serializable

    - by jenson-button-event
    I am storing an object in session state (using local session state server), class def is: [Serializable] public class ExtendedOAuth2Parameters : OAuth2Parameters but the service is still reporting: Unable to serialize the session state. In 'StateServer' and 'SQLServer' mode, ASP.NET will serialize the session state objects, and as a result non-serializable objects or MarshalByRef objects are not permitted. [SerializationException: Type 'Google.GData.Client.OAuth2Parameters' in Assembly 'Google.GData.Client, Version=2.1.0.0, Culture=neutral, PublicKeyToken=04a59ca9b0273830' is not marked as serializable.] How to get around it?

  • Questions about game states

    - by MrPlow
    I'm trying to make a framework for a game I've wanted to do for quite a while. The first thing that I decided to implement was a state system for game states. When my "original" idea of having a doubly linked list of game states failed I found This blog and liked the idea of a stack based game state manager. However there were a few things I found weird: Instead of RAII two class methods are used to initialize and destroy the state Every game state class is a singleton(and singletons are bad aren't they?) Every GameState object is static So I took the idea and altered a few things and got this: GameState.h class GameState { private: bool m_paused; protected: StateManager& m_manager; public: GameState(StateManager& manager) : m_manager(manager), m_paused(false){} virtual ~GameState() {} virtual void update() = 0; virtual void draw() = 0; virtual void handleEvents() = 0; void pause() { m_paused = true; } void resume() { m_paused = false; } void changeState(std::unique_ptr<GameState> state) { m_manager.changeState(std::move(state)); } }; StateManager.h class GameState; class StateManager { private: std::vector< std::unique_ptr<GameState> > m_gameStates; public: StateManager(); void changeState(std::unique_ptr<GameState> state); void StateManager::pushState(std::unique_ptr<GameState> state); void popState(); void update(); void draw(); void handleEvents(); }; StateManager.cpp StateManager::StateManager() {} void StateManager::changeState( std::unique_ptr<GameState> state ) { if(!m_gameStates.empty()) { m_gameStates.pop_back(); } m_gameStates.push_back( std::move(state) ); } void StateManager::pushState(std::unique_ptr<GameState> state) { if(!m_gameStates.empty()) { m_gameStates.back()->pause(); } m_gameStates.push_back( std::move(state) ); } void StateManager::popState() { if(!m_gameStates.empty()) m_gameStates.pop_back(); } void StateManager::update() { if(!m_gameStates.empty()) m_gameStates.back()->update(); } void StateManager::draw() { if(!m_gameStates.empty()) m_gameStates.back()->draw(); } void StateManager::handleEvents() { if(!m_gameStates.empty()) m_gameStates.back()->handleEvents(); } And it's used like this: main.cpp StateManager states; states.changeState( std::unique_ptr<GameState>(new GameStateIntro(states)) ); while(gamewindow::gameWindow.isOpen()) { states.handleEvents(); states.update(); states.draw(); } Constructors/Destructors are used to create/destroy states instead of specialized class methods, state objects are no longer static but

  • NTbackup doesn't complete on system state

    - by Joe Majsterski
    I have a Windows 2003 server that is running a semi-custom backup task. The scheduled task calls NTbackup with a few switches depending on whether it is a full or incremental backup. Most of the time, the NTbackup completes fine, and the wrapper then appends the NTbackup log into its own log before adding a few final comments and completing. The problem I am having is that sometimes, NTbackup seems to just... blank out. It always completes backup of the C: and E: drives, but then it will start the system state and not add any more messages into the event log saying it completed that. And the NTbackup log is left empty, since it doesn't write anything to the log until all the backup tasks are complete. This is causing the wrapper to append no text into its own log. That causes problems for us because we read the information out of that log to determine whether backups are failing. The wrapper task also reports that it is completing normally in the event log. Anyone ever seen a case where system state doesn't complete consistently? To be clear, the server is not logging any error messages anywhere. It's just not seeming to complete or log anything.

  • Error during Time Machine backups on OS X Lion

    - by user92401
    After I turn on my machine, the first couple of Time Machine backups seem to go OK, but after about an hour I get this error: Unable to complete backup. An error occurred while creating the backup folder. Latest successful backup: 7/31/11 at 12:32 PM I'm running 10.7. Time Machine is backing up an internal HD to an external USB HD.

  • Users in the field and Time Machine

    - by Bart Silverstrim
    We have several users in the field with MacBooks. Because they're not always on the network, they save files locally to their notebooks. Normally I back things up by making quick copies to other media, but with the Macs they have the option to run Time Machine (and the way OS X is designed, they're heavily encouraged to use it.) Question; for maintaining Macs and data, how reliable and thorough is Time Machine for backup/restoration? Does it just back up the user's home directory, or can it restore the Mac if, for example, the drive fails? And are there options for "securing" the data like corporate backup software for Windows does, to encrypt the data on the time machine drive?

  • How can I: Convert Physical to VM, the machine it's running on

    - by Daisetsu
    I have virtualized laptops before, when someone gets a new one and doesn't want to quite let go of their old laptop for fear of losing something. This was using VMWare Workstation 7.X. In 8.0 when I go to "Convert a Physical Machine to a Virtual Machine", it asks for an IP address and doesn't give the option to virtualize the machine it's running on. How to I get VMWare to virtualize it's current system? I tried typing in Localhost, and 127.0.0.1 but that didn't do it.

  • LAMP/TURNKEY LINUX/VIRTUAL BOX: Manipulating Files on a Virtual Machine

    - by aeid
    I am running Ubuntu 9.10 and I want to install turnkey linux's LAMP server on my machine to test out my code. I installed Turnkey LAMP via VirtualBox and it seems to be working because I can access the http://localhost. My question is: How do I manipulate files via VirtualBox? For example, if I had installed LAMP on my machine (not on a virtual machine), I could easily add/edit/delete files in the var/WWW folder. Where is the equivalent of "WWW" folder on Virtualbox and how can I interface with it? Thanks,

  • Partition External Harddrive already using Time Machine?

    - by Wex
    I have a 1TB external that I've used to backup my Mac for the past year using Time Machine. Unfortunately, my hard drive is getting close to full, and I'd like to move some of the stuff off of my Mac onto the same external drive. The problem is that the external drive is already full with my Time Machine Backups. I'd like to partition 750GB to the Time Machine Backups, and save the other 250GB for personal use. Is there any way I can go about this without corrupting my current backups? I'm willing to delete some of the older backups if necessary; again I'm just worried about corrupting the data.

  • Win XP Virtual Machine APP that won't START as a terminal services client

    - by Daniel
    I have a Win XP Virtual Machine APP that won't START as a terminal services client..... but if i disable terminal services inside the virtual machine, start the app then start terminal services... the APP runs fine (so long as terminal services are disabled when it starts.....!) My question is... is it possible to script things somehow so as to allow this app to be accessed directly from win 7 (with out having to manually run XP virtual machine)... I.E as I can not run it this way as it won't START with terminal services running.... I.e is it somehow possible to script things so the APP starts and terminal services is delayed then kicks in after a time delay.... (I know this may not be possible but I'm getting sick of all the mucking around...)

  • How to Configure a vm on the same machine to do remote desktop [closed]

    - by Varun K
    I want to achieve following: (Note I'd like to get this done first of all with Win7 as both host and vm OS) Install Windows 7/xp/Windows 8 VM on Windows 7/Windows 8 host machine Configure it so that I can connect to it via remote desktop. This is because I use a screen reader software and audio output directly from VMs is not highly responsive. My software has a feature that it can connect to its copy on the remote machine (during rdp session) and then start receiving the text description which it translates into audio on the client (host in this case) machine. I want to know: Which VM software can let me do this – VMWare/Ms Virtual PC or VirtualBox If it is possible with every VM software, could you give an example of how to do this with anyone of these 3? Specifically, I know how to install Windows on VM (on both VMWare/Virtual PC), but don't really know how to configure a network such that I can remote into that VM from host OS. Hope it clarifies what I'm trying to achieve.

  • Time Machine does not recognize my MacBook Pro

    - by qwertyuu
    Due to a clicking and beeping problem on my Macbook Pro (MBP), I got a 1 to 1 replacement from Apple which arrived today. I was able to my original setting using Time Machine restore. That works great. But after the restore and software update, the click on Time Machine to back up. But it says it doesn't recognize the backups. Now I am doing a full backup again that will take me a better of an hour. So what's the problem? How come Time Machine does not recognise the backups it restore from?

  • Time Machine (archive) of pre-Leopard systems?

    - by benc
    I want to get off an older Mac OS X system permanently. It is an iBook G3, so that has two important characteristics: Power PC, not Intel based. Runs only Tiger, not Leopard. This means, as far as I can tell: Cannot run Time Machine directly. Here's the approach I have been contemplating: Mount the drive in Firewire mode. Back up the drive as a external drive to the Time Machine volume. Disconnect the drive (permanently). However, I'm concerned that this drive will eventually age out, when the Time Machine volume fills up, and the old-system-as-external-drive is gone. Would it be better to do a single backup with another utility, to shared disk?

  • Time machine link error

    - by robinjam
    When attempting to perform a Time Machine backup, the backup appears to proceed as normal, until it finishes copying files at which point it complains that an "error occurred while linking files for" one of my external hard disks. During the previous backup that particular disk was in fact empty, and therefore I can't understand why Time Machine is attempting to link back to it. But alas. I've verified all my disks using Disk Utility and they all appear to be fine. Does anybody know what causes this error, and how I might go about fixing it? Failing that is there a way to force Time Machine to create a brand new backup rather than an incremental one? Thanks in advance!

  • Permissions restoring from Time Machine - Finder copy vs "cp" copy

    - by Ben Challenor
    Note: this question was starting to sprawl so I rewrote it. I have a folder that I'm trying to restore from a Time Machine backup. Using cp -R works fine, but certain folders cannot be restored with either the Time Machine UI or Finder. Other users have reported similar errors and the cp -R workaround was suggested (e.g. Restoring from Time Machine - Permissions Error). But I wanted to understand: Why cp -R works when the Finder and the Time Machine UI do not. Whether I could prevent the errors by changing file permissions before the backup. There do indeed seem to be some permissions that Finder works with and some that it does not. I've narrowed the errors down to folders with the user ben (that's me) and the group wheel. Here's a simplified reproduction. I have four folders with the owner/group combinations I've seen so far: ben ~/Desktop/test $ ls -lea total 16 drwxr-xr-x 7 ben staff 238 27 Nov 14:31 . drwx------+ 17 ben staff 578 27 Nov 14:29 .. 0: group:everyone deny delete -rw-r--r--@ 1 ben staff 6148 27 Nov 14:31 .DS_Store drwxr-xr-x 3 ben staff 102 27 Nov 14:30 ben-staff drwxr-xr-x 3 ben wheel 102 27 Nov 14:30 ben-wheel drwxr-xr-x 3 root admin 102 27 Nov 14:31 root-admin drwxr-xr-x 3 root wheel 102 27 Nov 14:31 root-wheel Each contains a single file called file with the same owner/group: ben ~/Desktop/test $ cd ben-staff ben ~/Desktop/test/ben-staff $ ls -lea total 0 drwxr-xr-x 3 ben staff 102 27 Nov 14:30 . drwxr-xr-x 7 ben staff 238 27 Nov 14:31 .. -rw-r--r-- 1 ben staff 0 27 Nov 14:30 file In the backup, they look like this: ben /Volumes/Deimos/Backups.backupdb/Ben’s MacBook Air/Latest/Macintosh HD/Users/ben/Desktop/test $ ls -leA total 16 -rw-r--r--@ 1 ben staff 6148 27 Nov 14:34 .DS_Store 0: group:everyone deny write,delete,append,writeattr,writeextattr,chown drwxr-xr-x@ 3 ben staff 102 27 Nov 14:51 ben-staff 0: group:everyone deny add_file,delete,add_subdirectory,delete_child,writeattr,writeextattr,chown drwxr-xr-x@ 3 ben wheel 102 27 Nov 14:51 ben-wheel 0: group:everyone deny add_file,delete,add_subdirectory,delete_child,writeattr,writeextattr,chown drwxr-xr-x@ 3 root admin 102 27 Nov 14:52 root-admin 0: group:everyone deny add_file,delete,add_subdirectory,delete_child,writeattr,writeextattr,chown drwxr-xr-x@ 3 root wheel 102 27 Nov 14:52 root-wheel 0: group:everyone deny add_file,delete,add_subdirectory,delete_child,writeattr,writeextattr,chown Of these, ben-staff can be restored with Finder without errors. root-wheel and root-admin ask for my password and then restore without errors. But ben-wheel does not prompt for my password and gives the error: The operation can’t be completed because you don’t have permission to access “file”. Interestingly, I can restore the file from this folder by dragging it directly to my local drive (instead of dragging its parent folder), but when I do so its permissions are changed to ben/staff. Here are the permissions after the restore for the three folders that worked correctly, and the file from ben-wheel that was changed to ben/staff. ben ~/Desktop/test-restore $ ls -leA total 16 -rw-r--r--@ 1 ben staff 6148 27 Nov 14:46 .DS_Store drwxr-xr-x 3 ben staff 102 27 Nov 14:30 ben-staff -rw-r--r-- 1 ben staff 0 27 Nov 14:30 file drwxr-xr-x 3 root admin 102 27 Nov 14:31 root-admin drwxr-xr-x 3 root wheel 102 27 Nov 14:31 root-wheel Can anyone explain this behaviour? Why do Finder and the Time Machine UI break with the ben / wheel permissions? And why does cp -R work (even without sudo)?

  • Strategy for restoring state via URL in web apps

    - by JW01
    This is a question about modern web apps, where a single page is loaded, and all subsequent navigation is done by XHR calls and modifying the DOM. We can use libraries that manipulate the hash string, which let us navigate by URL and support the back/forward buttons. But to use those libraries, we need to be able to move the UI from any one state to any other. Is there a good strategy for moving between UI states, that also allows them to be restored from scratch when you load a new URL? In a complex app, you might have a lot of different states. You don't want to reload the entire UI each time you change states. But you also don't want to require separate methods for moving from every state to each every state. Typically we need to: Restore a state from scratch, when you enter a new URL or hit Reload. Move from one state to another, when you use the Back/Forward buttons. Move from one state to another, when you perform an action within your app (like clicking a link). Move to certain states that shouldn't be added to the history, like ones that appear after form submissions. Move to some states that are built on the previous state, like a drill-down list. When you perform actions within your app, there's the additional question of which comes first: Do you change the URL, listen for the URL change, and change your state in response to it? Or do you change your state, then change the URL, but don't do anything in response? Does anyone have some experience to share on this topic?

  • Are Time Machine backups secure?

    - by Leandro Ardissone
    I have my Time Machine backups on an external disk (WD My Passport with no hardware encryption) and I'm worried if the data stored on the disk is safe in case somebody steals it and connect it to any Mac/PC. Does any Mac can browse the Time Machine backups? Or are they encrypted in any way? If no, is there a way to improve security of the backups, should I buy a hardware encryption based HD? Thanks.

  • Cannot access virtual machine via ping from the physical host machine

    - by Kenni
    I'm installing a FreeBSD Server on VirtualBox. I set up the IP address (192.168.10.5) for the virtual server to run a mail server and the host computer(Windows 7) with 192.168.10.184. The two machines cannot communicate or connect to each other. I cannot ping from the virtual machine to the host and vice versa. The host machine connects to a LAN. I want the mail server to run frm a VMachine. I think it's a problem with the network configuration of the virtual machine.

The connection with the tfs server is made but the project content remains empty. Web access is possible from this machine. Note: from all other machines everything works normally, so it must be a local machine issue. What might be misconfigured on this machine? Otherwise there seem to be no problems on this XP machine.

  • I want to build a Virtual Machine, are there any good references?

    - by Michael Stum
    I'm looking to build a Virtual Machine as a platform independent way to run some game code (essentially scripting). The Virtual Machines that I'm aware of in games are rather old: Infocom's Z-Machine, LucasArts' SCUMM, id Software's Quake 3. As a .net Developer, I'm familiar with the CLR and looked into the CIL Instructions to get an overview of what you actually implement on a VM Level (vs. the language level). I've also dabbled a bit in 6502 Assembler during the last year. The thing is, now that I want¹ to implement one, I need to dig a bit deeper. I know that there are stack based and register based VMs, but I don't really know which one is better at what and if there are more or hybrid approaches. I need to deal with memory management, decide which low level types are part of the VM and need to understand why stuff like ldstr works the way it does. My only reference book (apart from the Z-Machine stuff) is the CLI Annotated Standard, but I wonder if there is a better, more general/fundamental lecture for VMs? Basically something like the Dragon Book, but for VMs? I'm aware of Donald Knuth's Art of Computer Programming which uses a register-based VM, but I'm not sure how applicable that series still is, especially since it's still unfinished? Clarification: The goal is to build a specialized VM. For example, Infocom's Z-Machine contains OpCodes for setting the Background Color or playing a sound. So I need to figure out how much goes into the VM as OpCodes vs. the compiler that takes a script (language TBD) and generates the bytecode from it, but for that I need to understand what I'm really doing. ¹ I know, modern technology would allow me to just interpret a high level scripting language on the fly. But where is the fun in that? :) It's also a bit hard to google because Virtual Machines is nowadays often associated with VMWare-type OS Virtualization...
