  • I'm trying to install VMWare tools on Ubuntu 12.04.2 LTS and I seem to have a problem with Kernel headers

    - by Pedro Irusta
    I have Ubuntu 12.04.2 LTS installed on a VMware machine on Windows 7 host. I seem to have a problem with Kernel headers when trying to install them I did: sudo apt-get install gcc make build-essential linux-headers-$(uname -r) Reading package lists... Done Building dependency tree Reading state information... Done gcc is already the newest version. build-essential is already the newest version. linux-headers-3.5.0-28-generic is already the newest version. make is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 100 not upgraded. However, when installing VMware tools I get the following error: make[1]: Entering directory `/usr/src/linux-headers-3.5.0-28-generic' CC [M] /tmp/vmware-root/modules/vmhgfs-only/backdoor.o CC [M] /tmp/vmware-root/modules/vmhgfs-only/backdoorGcc32.o CC [M] /tmp/vmware-root/modules/vmhgfs-only/bdhandler.o CC [M] /tmp/vmware-root/modules/vmhgfs-only/cpName.o CC [M] /tmp/vmware-root/modules/vmhgfs-only/cpNameLinux.o CC [M] /tmp/vmware-root/modules/vmhgfs-only/cpNameLite.o CC [M] /tmp/vmware-root/modules/vmhgfs-only/dentry.o CC [M] /tmp/vmware-root/modules/vmhgfs-only/dir.o CC [M] /tmp/vmware-root/modules/vmhgfs-only/file.o /tmp/vmware-root/modules/vmhgfs-only/file.c:122:4: warning: initialization from incompatible pointer type [enabled by default] /tmp/vmware-root/modules/vmhgfs-only/file.c:122:4: warning: (near initialization for ‘HgfsFileFileOperations.fsync’) [enabled by default] CC [M] /tmp/vmware-root/modules/vmhgfs-only/filesystem.o /tmp/vmware-root/modules/vmhgfs-only/filesystem.c:48:28: fatal error: linux/smp_lock.h: No such file or directory compilation terminated. make[2]: *** [/tmp/vmware-root/modules/vmhgfs-only/filesystem.o] Error 1 make[1]: *** [_module_/tmp/vmware-root/modules/vmhgfs-only] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-3.5.0-28-generic' make: *** [vmhgfs.ko] Error 2 make: Leaving directory `/tmp/vmware-root/modules/vmhgfs-only' Any help appreciated!

  • route lan traffic through wirless mifi

    - by Randall Blake
    I have a Windows 7 laptop accessing the internet through Verizon wireless MIFI configured as 192.168.1.1. It supports only 5 wireless connections, so I don't want to use up connections unnecessarily. That laptop has an ethernet nic which I have given a static IP of 192.168.0.5. Everything else on the 192.168.0.0 network acquires an address via DHCP from a DLink router whose address is 192.168.0.1. Also on that network are a printer, some network cameras, and a linux pc. The linux pc does not have a wireless card (and I don't want to buy one). The linux pc is located at 192.168.0.122. I can ping the linux pc from the windows pc. But I cannot access the internet from the linux pc. I can ping everything on the 192.168.0.0 network EXCEPT the ethernet card in the Windows PC. It seems as though my DLink router will not route requests to the 192.168.0.5 nic on the windows pc. My windows pc has a default route pointing to the 192.168.1.0 network. It also has a route telling it to route all traffic destined for the 192.168.0.0 network through the 192.168.0.5 interface. I have tried adding a default route to the linux pc to "gateway" 192.168.0.5, but that does not work. I have also tried adding a default route to the linux pc to the gateway 192.168.0.1 (the DLink router) but that will not give me internet access either (over the 192.168.1.0 network). I tried these two different routes at different times - I did not set them both at the same time. I suppose this is a simple problem to solve, but I cannot seem to solve it. How can I give internet access over the 192.168.1.1 MIFI to my linux pc on 192.168.0.122? Thanks EDIT: Additional Info Internet | | MIFI (192.168.1.1) (wireless) | | (192.168.1.3) (wireless) Windows 7 PC Dlink Router (192.168.0.1) ------------ (192.168.0.5) (wired) | | |linux pc (192.168.0.122) (wired) | |printer (192.168.0.100) (wireless) | |network cameras, etc (192.168.0.103) (wireless) Only the windows pc is multi-homed with a wireless nic that connects to the MIFI wirelessly, and an ethernet nic with a wired connection to the DLink router. (The DLink permits both wired and wireless connections.) I don't want to use Windows internet connection sharing because I believe it will set up the ethernet nic as a gateway on 192.168.0.1 and a DHCP server. I already have the Dlink performing that role and I don't want to change that if I do not have to. (The Dlink permits me to make DHCP reservations and I really like that feature. I don't want to lose it.)

  • Where to store front-end data for "object calculator"

    - by Justin Grahn
    I recently have completed a language library that acts as a giant filter for food items, and flows a bit like this :Products -> Recipes -> MenuItems -> Meals and finally, upon submission, creates an Order. I have also completed a database structure that stores all the pertinent information to each class, and seems to fit my needs. The issue I'm having is linking the two. I imagined all of the information being local to each instance of the product, where there exists one backend user who edits and manipulates data, and multiple front end users who select their Meal(s) to create an Order. Ideally, all of the front end users would have all of this information stored locally within the library, and would update the library on startup from a database. How should I go about storing the data so that I can load it into the library every time the user opens the application? Do I package a database onboard and just load and populate every time? The only method I can currently conceive of doing this, even if I only have 500 possible Product objects, would require me to foreach the list for every Product that I need to match to a Recipe and so on and so forth every time I relaunch the program, which seems like a lot of wasteful loading. Here is a general flow of my architecture: Products: public class Product : IPortionable { public Product(string n, uint pNumber = 0) { name = n; productNumber = pNumber; } public string name { get; set; } public uint productNumber { get; set; } } Recipes: public Recipe(string n, decimal yieldAmt, Volume.Unit unit) { name = n; yield = new Volume(yieldAmt, unit); yield.ConvertUnit(); } /// <summary> /// Creates a new ingredient object /// </summary> /// <param name="n">Name</param> /// <param name="yieldAmt">Recipe Yield</param> /// <param name="unit">Unit of Yield</param> public Recipe(string n, decimal yieldAmt, Weight.Unit unit) { name = n; yield = new Weight(yieldAmt, unit); } public Recipe(Recipe r) { name = r.name; yield = r.yield; ingredients = r.ingredients; } public string name { get; set; } public IMeasure yield; public Dictionary<IPortionable, IMeasure> ingredients = new Dictionary<IPortionable,IMeasure>(); MenuItems: public abstract class MenuItem : IScalable { public static string title = null; public string name { get; set; } public decimal maxPortionSize { get; set; } public decimal minPortionSize { get; set; } public Dictionary<IPortionable, IMeasure> ingredients = new Dictionary<IPortionable, IMeasure>(); and Meal: public class Meal { public Meal(int guests) { guestCount = guests; } public int guestCount { get; private set; } //TODO: Make a new MainCourse class that holds pasta and Entree public Dictionary<string, int> counts = new Dictionary<string, int>(){ {MainCourse.title, 0}, {Side.title , 0}, {Appetizer.title, 0} }; public List<MenuItem> items = new List<MenuItem>(); The Database just stores and links each of these basic names and amounts together usings ID's (RecipeID, ProductID and MenuItemID)

  • SOLID Principles and code structure

    - by S-Unit
    My question is on SOLID principles, because I couldn't answer a question (beyond the obvious meaning of the various principles of SOLID) at an interview and it really bugs me. I have done a couple of days worth of digging around and have yet to come up with a satisfactory summary. The question was: If you were to look at a .Net project that I told you strictly followed SOLID principles, what would expect to see in terms of the project and code structure ? I sort of floundered around a bit, didn't really answer the question and then bombed out. Any help or thoughts will really be appreciated.

  • Creating a backup - Rsync - Connection refused (111)

    - by pablofiumara
    I am trying to create a backup of my website for free. I just want to have a backup of my website, including not only all files and the configuration but also the databases. I mean, a full backup. If it can be done automatically, it would be better. I feel there are better ways than using the cpanel to achieve that (actually, I believe sometimes web hosters does not have any cpanel). I read the following on how to do it: Automatically mirror the entire contents and configuration of your main server to a secondary backup server on a completely separate network in a different data centre. Use RSync, FXP, cPanel voodoo, or whatever method you wish to automate syncing. That is why I installed Rsync Daemon which is an alternative to SSH for remote backups. I configured it but the test went wrong. The terminal is showing me this: pablofiumara@pablofiumara-Lenovo-G470:~$ sudo rsync [email protected]::share [sudo] password for pablofiumara: rsync: failed to connect to pablofiumara.com (50.87.147.75): Connection refused (111) rsync error: error in socket IO (code 10) at clientserver.c(122) [Receiver=3.0.9] pablofiumara@pablofiumara-Lenovo-G470:~$ sudo rsync [email protected]::share failed to connect to 50.87.147.7 (50.87.147.7): Connection refused (111) rsync error: error in socket IO (code 10) at clientserver.c(122) [Receiver=3.0.9] What should I do? Is there a better or easier way to achieve what I wish (I mentioned this in the first paragraph)?

  • Error while trying to configure VLAN with Open vSwitch

    - by Abhishek Chanda
    I am trying to connect a number of VMs using Open vSwitch. The VMs are on two separate physical boxes. Here is what I did: Created two tap devices on one physical host sudo ip tuntap add mode tap tap0 and same for tap1 Bring them up sudo ip link set tap0 up Add them as ports to Open vSwitch (br0 was created as a OVS bridge previously) sudo ovs-vsctl add-port br0 tap0 tag=1 Now I booted the VMs (using VirtualBox) and assigned addresses 192.168.122.11 and 192.168.122.12. Now when I try to ping one VM from another, I get the error Connect: network is unreachable. Since both VMs are connected to the switch on the same VLAN, I expect to be able to ping one from another. What is going wrong here?

  • DNS no longer works after server reboot

    - by Burning the Codeigniter
    Strangely enough, when I reboot my Ubuntu 12.04 server, the DNS no longer works, which makes the domain unavailable to access to my site. Normally the DNS should be working after a reboot, but this doesn't happen anymore. I use nginx to serve content, but nginx is already configured to work with my domains. What are the typical practises must I do after a reboot and how can I solve this issue I experience?

  • Matlab help: I am given a second order differential equation.I need to use matlab to find unit step response and impulse response?

    - by Cady Smith
    I have the second order differential equation d^2(y(t))/dt^2+ B1*d(y(t))/dt+ c1*y(t)=A1*x(t) t is in seconds and is greater than 0. A1, B1, C1 are constants that equal: A1= 3.8469x10^6 B1= 325.6907 C1= 3.8469x10^6 This system is linear, time-invariant, and casual. The system is called H1. I want to use Matlab to compute and plot the impulse response function h1(t) and the unit step response function g1(t) of this system.

  • Applications: The Mathematics of Movement, Part 3

    - by TechTwaddle
    Previously: Part 1, Part 2 As promised in the previous post, this post will cover two variations of the marble move program. The first one, Infinite Move, keeps the marble moving towards the click point, rebounding it off the screen edges and changing its direction when the user clicks again. The second version, Finite Move, is the same as first except that the marble does not move forever. It moves towards the click point, rebounds off the screen edges and slowly comes to rest. The amount of time that it moves depends on the distance between the click point and marble. Infinite Move This case is simple (actually both cases are simple). In this case all we need is the direction information which is exactly what the unit vector stores. So when the user clicks, you calculate the unit vector towards the click point and then keep updating the marbles position like crazy. And, of course, there is no stop condition. There’s a little more additional code in the bounds checking conditions. Whenever the marble goes off the screen boundaries, we need to reverse its direction.  Here is the code for mouse up event and UpdatePosition() method, //stores the unit vector double unitX = 0, unitY = 0; double speed = 6; //speed times the unit vector double incrX = 0, incrY = 0; private void Form1_MouseUp(object sender, MouseEventArgs e) {     double x = e.X - marble1.x;     double y = e.Y - marble1.y;     //calculate distance between click point and current marble position     double lenSqrd = x * x + y * y;     double len = Math.Sqrt(lenSqrd);     //unit vector along the same direction (from marble towards click point)     unitX = x / len;     unitY = y / len;     timer1.Enabled = true; } private void UpdatePosition() {     //amount by which to increment marble position     incrX = speed * unitX;     incrY = speed * unitY;     marble1.x += incrX;     marble1.y += incrY;     //check for bounds     if ((int)marble1.x < MinX + marbleWidth / 2)     {         marble1.x = MinX + marbleWidth / 2;         unitX *= -1;     }     else if ((int)marble1.x > (MaxX - marbleWidth / 2))     {         marble1.x = MaxX - marbleWidth / 2;         unitX *= -1;     }     if ((int)marble1.y < MinY + marbleHeight / 2)     {         marble1.y = MinY + marbleHeight / 2;         unitY *= -1;     }     else if ((int)marble1.y > (MaxY - marbleHeight / 2))     {         marble1.y = MaxY - marbleHeight / 2;         unitY *= -1;     } } So whenever the user clicks we calculate the unit vector along that direction and also the amount by which the marble position needs to be incremented. The speed in this case is fixed at 6. You can experiment with different values. And under bounds checking, whenever the marble position goes out of bounds along the x or y direction we reverse the direction of the unit vector along that direction. Here’s a video of it running;   Finite Move The code for finite move is almost exactly same as that of Infinite Move, except for the difference that the speed is not fixed and there is an end condition, so the marble comes to rest after a while. Code follows, //unit vector along the direction of click point double unitX = 0, unitY = 0; //speed of the marble double speed = 0; private void Form1_MouseUp(object sender, MouseEventArgs e) {     double x = 0, y = 0;     double lengthSqrd = 0, length = 0;     x = e.X - marble1.x;     y = e.Y - marble1.y;     lengthSqrd = x * x + y * y;     //length in pixels (between click point and current marble pos)     length = Math.Sqrt(lengthSqrd);     //unit vector along the same direction as vector(x, y)     unitX = x / length;     unitY = y / length;     speed = length / 12;     timer1.Enabled = true; } private void UpdatePosition() {     marble1.x += speed * unitX;     marble1.y += speed * unitY;     //check for bounds     if ((int)marble1.x < MinX + marbleWidth / 2)     {         marble1.x = MinX + marbleWidth / 2;         unitX *= -1;     }     else if ((int)marble1.x > (MaxX - marbleWidth / 2))     {         marble1.x = MaxX - marbleWidth / 2;         unitX *= -1;     }     if ((int)marble1.y < MinY + marbleHeight / 2)     {         marble1.y = MinY + marbleHeight / 2;         unitY *= -1;     }     else if ((int)marble1.y > (MaxY - marbleHeight / 2))     {         marble1.y = MaxY - marbleHeight / 2;         unitY *= -1;     }     //reduce speed by 3% in every loop     speed = speed * 0.97f;     if ((int)speed <= 0)     {         timer1.Enabled = false;     } } So the only difference is that the speed is calculated as a function of length when the mouse up event occurs. Again, this can be experimented with. Bounds checking is same as before. In the update and draw cycle, we reduce the speed by 3% in every cycle. Since speed is calculated as a function of length, speed = length/12, the amount of time it takes speed to reach zero is directly proportional to length. Note that the speed is in ‘pixels per 40ms’ because the timeout value of the timer is 40ms.  The readability can be improved by representing speed in ‘pixels per second’. This would require you to add some more calculations to the code, which I leave out as an exercise. Here’s a video of this second version,

  • How do I make the manifest available during a Maven/Surefire unittest run "mvn test" ?

    - by Ernst de Haan
    How do I make the manifest available during a Maven/Surefire unittest run "mvn test" ? I have an open-source project that I am converting from Ant to Maven, including its unit tests. Here's the project source repository with the Maven project: http://github.com/znerd/logdoc My question pertains to the primary module, called "base". This module has a unit test that tests the behaviour of the static method getVersion() in the class org.znerd.logdoc.Library. This method returns: Library.class.getPackage().getImplementationVersion() The getImplementationVersion() method returns a value of a setting in the manifest file. So far, so good. I have tested this in the past and it works well, as long as the manifest is indeed available on the classpath at the path META-INF/MANIFEST.MF (either on the file system or inside a JAR file). Now my challenge is that the manifest file is not available when I run the unit tests: mvn test Surefire runs the unit tests, but my unit test fails with a mesage indicating that Library.getVersion() returned null. When I want to check the JAR, I find that it has not even been generated. Maven/Surefire runs the unit tests against the classes, before the resources are added to the classpath. So can I either run the unit tests against the JAR (implicitly requiring the JAR to be generated first) or can I make sure the resources (including the manifest file) are generated/copied under target/classes before the unit tests are run? Note that I use Maven 2.2.0, Java 1.6.0_17 on Mac OS X 10.6.2, with JUnit 4.8.1.

  • MySQL unstable behavior with external stroge

    - by onurozcelik
    In our project we are using MySQL 5.0.90(InnoDB engine) server with an external storage. We store MySQL data files in an external storage. When the external storage down for a reason we have unstable behaviours. So we made some tests. In Windows Server 2008 We closed external storage physically. MySQL service stoped and we could not reach the server. Then we opened the storage unit and we could not start service until we reconfigured MySQL. We made storage unit offline from operating system. After 3-4 minutes and some insert trials(some insert trials succeded) MySQL service stoped and we could not reach the server. Then we made storage unit online and we could start the service(not automatically). In Windows Server 2003 We made storage unit offline. After 3-4 minutes and some insert trials(some insert trials succeded) MySQL service stoped and we could not reach the server. Then we made storage unit online we could not start the service until we reinstalled MySQL. Before reinstall we tried to reconfigure but it did not work. We closed external storage physically. MySQL service stoped and we could not reach the server. After that we opened the storage unit and we could start service(not automatically) We expect service to autostart after storage unit is online/open. But these tests show unstable behaviors. Is there any solutions to this.
