  • Xubuntu: how do I automatically mount external NTFS drive with writes allowed?

    - by user74372
    i would have thought mine was such a common question that there would be a simple solution already built in to xubuntu - but there isnt. i have 2 separate external hard disks and connect them to a usb port at different times - i would like them to be automatically mounted as read/write, but apparently the designers of gnome-volume-manager decided that shouldnt be possible and they are mounted as read-only in fact, i can write new files to them, but cannot then delete the new files i just wrote! is there a workaround? i read somewhere that etc/fstab doesn't apply to removable media, which are mounted by gnome-volume-manager and therefore cannot be unmounted by a user

  • Using VBA to model data in Autodesk Inventor?

    - by user108478
    I have a close friend who is using a specific device that records the dimensions of an object as it is eroded and outputs the dimensional data to an excel sheet. The object is spherical in nature but is eroded from the top and bottom, so the shape is constantly changing and a single formula for surface area and volume would not work. This is where Inventor comes in. My friend can plug the dimensional data to Inventor and it immediately returns the surface area and volume. The erosion process takes several minutes to complete and records data at very short intervals, so it would be very arduous to plug in the data thousand of time. Since Inventor supports macros and VBA, is there a way to plug the data into Inventor and output it into another spreadsheet? Any suggestions would be appreciated.

  • ASUS Xonar DG not working Ubuntu

    - by thephpdev
    I've checked the "Questions that may already have your answer" to no avail. Basically, there is no sound at all, the snd_oxygen drivers are all being loaded. I can see the sound card and all of it's separate ports in Settings-Sound-Output, but nothing is coming out. I tried adjusting the volume in alsamixer, but for some reason the volume won't change (all that is there are some options [Speakers, Headphones, FP Headphones] and they change when I press the up/down arrow keys) at all. I have also tried many other terminal commands, such as reloading alsa and checking if the sound card is even being detected, which it is. I'm left clueless. It says on a bug report that this has been unassigned for over a year. Surely that's not right. Thanks in advance, Caelan.

  • Why would Linux VM in vSphere ESXi 5.5 show dramatically increased disk i/o latency?

    - by mhucka
    I'm stumped and I hope someone else will recognize the symptoms of this problem. Hardware: new Dell T110 II, dual-core Pentium G860 2.9 GHz, onboard SATA controller, one new 500 GB 7200 RPM cabled hard drive inside the box, other drives inside but not mounted yet. No RAID. Software: fresh CentOS 6.5 virtual machine under VMware ESXi 5.5.0 (build 174 + vSphere Client). 2.5 GB RAM allocated. The disk is how CentOS offered to set it up, namely as a volume inside an LVM Volume Group, except that I skipped having a separate /home and simply have / and /boot. CentOS is patched up, ESXi patched up, latest VMware tools installed in the VM. No users on the system, no services running, no files on the disk but the OS installation. I'm interacting with the VM via the VM virtual console in vSphere Client. Before going further, I wanted to check that I configured things more or less reasonably. I ran the following command as root in a shell on the VM: for i in 1 2 3 4 5 6 7 8 9 10; do dd if=/dev/zero of=/test.img bs=8k count=256k conv=fdatasync done I.e., just repeat the dd command 10 times, which results in printing the transfer rate each time. The results are disturbing. It starts off well: 262144+0 records in 262144+0 records out 2147483648 bytes (2.1 GB) copied, 20.451 s, 105 MB/s 262144+0 records in 262144+0 records out 2147483648 bytes (2.1 GB) copied, 20.4202 s, 105 MB/s ... but after 7-8 of these, it then prints 262144+0 records in 262144+0 records out 2147483648 bytes (2.1 GG) copied, 82.9779 s, 25.9 MB/s 262144+0 records in 262144+0 records out 2147483648 bytes (2.1 GB) copied, 84.0396 s, 25.6 MB/s 262144+0 records in 262144+0 records out 2147483648 bytes (2.1 GB) copied, 103.42 s, 20.8 MB/s If I wait a significant amount of time, say 30-45 minutes, and run it again, it again goes back to 105 MB/s, and after several rounds (sometimes a few, sometimes 10+), it drops to ~20-25 MB/s again. Plotting the disk latency in vSphere's interface, it shows periods of high disk latency hitting 1.2-1.5 seconds during the times that dd reports the low throughput. (And yes, things get pretty unresponsive while that's happening.) What could be causing this? I'm comfortable that it is not due to the disk failing, because I also had configured two other disks as an additional volume in the same system. At first I thought I did something wrong with that volume, but after commenting the volume out from /etc/fstab and rebooting, and trying the tests on / as shown above, it became clear that the problem is elsewhere. It is probably an ESXi configuration problem, but I'm not very experienced with ESXi. It's probably something stupid, but after trying to figure this out for many hours over multiple days, I can't find the problem, so I hope someone can point me in the right direction. (P.S.: yes, I know this hardware combo won't win any speed awards as a server, and I have reasons for using this low-end hardware and running a single VM, but I think that's besides the point for this question [unless it's actually a hardware problem].) ADDENDUM #1: Reading other answers such as this one made me try adding oflag=direct to dd. However, it makes no difference in the pattern of results: initially the numbers are higher for many rounds, then they drop to 20-25 MB/s. (The initial absolute numbers are in the 50 MB/s range.) ADDENDUM #2: Adding sync ; echo 3 > /proc/sys/vm/drop_caches into the loop does not make a difference at all. ADDENDUM #3: To take out further variables, I now run dd such that the file it creates is larger than the amount of RAM on the system. The new command is dd if=/dev/zero of=/test.img bs=16k count=256k conv=fdatasync oflag=direct. Initial throughput numbers with this version of the command are ~50 MB/s. They drop to 20-25 MB/s when things go south. ADDENDUM #4: Here is the output of iostat -d -m -x 1 running in another terminal window while performance is "good" and then again when it's "bad". (While this is going on, I'm running dd if=/dev/zero of=/test.img bs=16k count=256k conv=fdatasync oflag=direct.) First, when things are "good", it shows this: When things go "bad", iostat -d -m -x 1 shows this:

  • Video Bug in Ubuntu 12.10 MSI CX623 laptop

    - by user104731
    http://www.youtube.com/watch?v=5xyJkS8XjgA&feature=youtu.be I managed to take a video with what happens on my Ubuntu 12.10 laptop when I play with the volume and hover with the mouse over the slider and when I press Ctrl + Alt + D (show Desktop/minimize all) The real bugs are those in which the panel becomes transparent on the down side, exactly above the volume slider (and not only when that slider appears, but also when brightness slider appears, and when blocking my touchpad applet appears) and when I have a maximized window, more maximized windows or a non maximized window that touches the panel, while I use Ctrl+Alt+D (show Desktop/hide all normal windows). Is there a way to solve this bug? PS: The other bugs are from Record My Desktop. I didn't have the mentioned bugs in ubuntu 12.04, but I like more the graphics in 12.10.

  • Is there a way of leveling/compressing the sound system-wide?

    - by JethroDawnfine
    As a Laptop user, I'm sure that a lot of people, even the ones using Netbooks would have already gone through this problem. Especially when listening to podcasts, and using it as an example, the sound might have loud moments and quiet moments, one person speaking loud and the other speaking very quiet in the same episode. Thereby, I always wanted the sound to be compressed system-wide, and I just noted the other day, that in Windows, some Realtek drivers already offer this function. We have already a pulseaudio plugin for equalization system-wide, and although it still has problems like not letting us change its values and listen the change in real time, or cracking the sound while changing pulse volume, I do love it and use it. Now I'm just missing something to keep the sound around 0db (or near the volume level you're using) as a leveler plugin for pulseaudio. Any suggestion?

  • OpenGL - Frustum not culling polygons beyond far plane

    - by Pladnius Brooks
    I have implemented frustum culling and am checking the bounding box for its intersection with the frustum planes. I added the ability to pause frustum updates which lets me see if the frustum culling has been working correctly. When I turn around after I have paused it, nothing renders behind me and to the left and right side, they taper off as well just as you would expect. Beyond the clip distance (far plane), they still render and I am not sure whether it is a problem with my frustum updating or bounding box checking code or I am using the wrong matrix or what. As I put the distance in the projection matrix at 3000.0f, it still says that bounding boxes well past that are still in the frustum, which isn't the case. Here is where I create my modelview matrix: projectionMatrix = glm::perspective(newFOV, 4.0f / 3.0f, 0.1f, 3000.0f); viewMatrix = glm::mat4(1.0); viewMatrix = glm::scale(viewMatrix, glm::vec3(1.0, 1.0, -1.0)); viewMatrix = glm::rotate(viewMatrix, anglePitch, glm::vec3(1.0, 0.0, 0.0)); viewMatrix = glm::rotate(viewMatrix, angleYaw, glm::vec3(0.0, 1.0, 0.0)); viewMatrix = glm::translate(viewMatrix, glm::vec3(-x, -y, -z)); modelViewProjectiomMatrix = projectionMatrix * viewMatrix; The reason I scale it by -1 in the Z direction is because the levels were designed to be rendered with DirectX so I reverse the Z direction. Here is where I update my frustum: void CFrustum::calculateFrustum() { glm::mat4 mat = camera.getModelViewProjectionMatrix(); // Calculate the LEFT side m_Frustum[LEFT][A] = (mat[0][3]) + (mat[0][0]); m_Frustum[LEFT][B] = (mat[1][3]) + (mat[1][0]); m_Frustum[LEFT][C] = (mat[2][3]) + (mat[2][0]); m_Frustum[LEFT][D] = (mat[3][3]) + (mat[3][0]); // Calculate the RIGHT side m_Frustum[RIGHT][A] = (mat[0][3]) - (mat[0][0]); m_Frustum[RIGHT][B] = (mat[1][3]) - (mat[1][0]); m_Frustum[RIGHT][C] = (mat[2][3]) - (mat[2][0]); m_Frustum[RIGHT][D] = (mat[3][3]) - (mat[3][0]); // Calculate the TOP side m_Frustum[TOP][A] = (mat[0][3]) - (mat[0][1]); m_Frustum[TOP][B] = (mat[1][3]) - (mat[1][1]); m_Frustum[TOP][C] = (mat[2][3]) - (mat[2][1]); m_Frustum[TOP][D] = (mat[3][3]) - (mat[3][1]); // Calculate the BOTTOM side m_Frustum[BOTTOM][A] = (mat[0][3]) + (mat[0][1]); m_Frustum[BOTTOM][B] = (mat[1][3]) + (mat[1][1]); m_Frustum[BOTTOM][C] = (mat[2][3]) + (mat[2][1]); m_Frustum[BOTTOM][D] = (mat[3][3]) + (mat[3][1]); // Calculate the FRONT side m_Frustum[FRONT][A] = (mat[0][3]) + (mat[0][2]); m_Frustum[FRONT][B] = (mat[1][3]) + (mat[1][2]); m_Frustum[FRONT][C] = (mat[2][3]) + (mat[2][2]); m_Frustum[FRONT][D] = (mat[3][3]) + (mat[3][2]); // Calculate the BACK side m_Frustum[BACK][A] = (mat[0][3]) - (mat[0][2]); m_Frustum[BACK][B] = (mat[1][3]) - (mat[1][2]); m_Frustum[BACK][C] = (mat[2][3]) - (mat[2][2]); m_Frustum[BACK][D] = (mat[3][3]) - (mat[3][2]); // Normalize all the sides NormalizePlane(m_Frustum, LEFT); NormalizePlane(m_Frustum, RIGHT); NormalizePlane(m_Frustum, TOP); NormalizePlane(m_Frustum, BOTTOM); NormalizePlane(m_Frustum, FRONT); NormalizePlane(m_Frustum, BACK); } And finally, where I check the bounding box: bool CFrustum::BoxInFrustum( float x, float y, float z, float x2, float y2, float z2) { // Go through all of the corners of the box and check then again each plane // in the frustum. If all of them are behind one of the planes, then it most // like is not in the frustum. for(int i = 0; i < 6; i++ ) { if(m_Frustum[i][A] * x + m_Frustum[i][B] * y + m_Frustum[i][C] * z + m_Frustum[i][D] > 0) continue; if(m_Frustum[i][A] * x2 + m_Frustum[i][B] * y + m_Frustum[i][C] * z + m_Frustum[i][D] > 0) continue; if(m_Frustum[i][A] * x + m_Frustum[i][B] * y2 + m_Frustum[i][C] * z + m_Frustum[i][D] > 0) continue; if(m_Frustum[i][A] * x2 + m_Frustum[i][B] * y2 + m_Frustum[i][C] * z + m_Frustum[i][D] > 0) continue; if(m_Frustum[i][A] * x + m_Frustum[i][B] * y + m_Frustum[i][C] * z2 + m_Frustum[i][D] > 0) continue; if(m_Frustum[i][A] * x2 + m_Frustum[i][B] * y + m_Frustum[i][C] * z2 + m_Frustum[i][D] > 0) continue; if(m_Frustum[i][A] * x + m_Frustum[i][B] * y2 + m_Frustum[i][C] * z2 + m_Frustum[i][D] > 0) continue; if(m_Frustum[i][A] * x2 + m_Frustum[i][B] * y2 + m_Frustum[i][C] * z2 + m_Frustum[i][D] > 0) continue; // If we get here, it isn't in the frustum return false; } // Return a true for the box being inside of the frustum return true; }

  • uniform generation of 3D points on cylinder/cone

    - by Myx
    Hello: I wish to randomly and uniformly generate points on a cylinder and a cone (separately). The cylinder is defined by its center, its radius and height. Same specifications for the cone. I am able to get the bounding box for each shape so I was thinking of generating points within the bounding box. However, I'm not sure how to project them onto the cylinder/cone or if this is the best idea. Any suggestions? Thanks.

  • Texture coordintes for a polygon and a square texture

    - by user146780
    basically I have a texture. I also have a lets say octagon (or any polygon). I find that octagon's bounding box. Let's say my texture is the size of the octagon's bounding box. How could I figure out the texture coordinates so that the texture maps to it. To clarify, lets say you had a square of tin foil and cut the octagon out you'd be left with a tin foil textured polygon.I'm just not sure how to figure it out for an arbitrary polygon. Thanks

  • Placing an background image with padding in h2 tag

    - by Cedar Jensen
    I want to create a headline (h2) with an image at the right-most area of the bounding box. I have the layout almost right except I can't push the image a little bit to the right of the element's bounding box -- how would I tweak my css so it is displayed correctly? I'm trying to do something like this: [{someHeadLineText}{dynamic space }{image}{5px space}] where the [] indicate the total available width of my content. Html: <div class="primaryHeader"> <h2>News</h2> </div> Css: .primaryHeader h2 { background-color: green; /* the header looks like a box */ color: black; background: transparent url(../images/edit.png) no-repeat right center; border: 1px solid red; } I am placing the image to the right of my h2 element and centered vertically -- but how do I adjust the placement of the background image?

  • Manage dirty rect efficiently

    - by Tianzhou Chen
    Hi all, I am implementing a view system and I want to keep track of all the dirty rects. It seems my dirty rect management is a bottleneck for the whole system. On one hand, invalidating the bounding box of the dirty region seems to be an easy approach. But in the situation like this: Say I have a client area of 100x100; I have a dirty rect with (0, 0, 1, 1) and another dirty rect with (99, 99, 1, 1). Invalidating the bounding box which turns out to be 100x100 is not efficient at all. So I want to ask if someone can give any hint or give me a link of the related literatures. Thanks in advance!

  • Best way to search a point across several polygons

    - by user1474341
    I have a requirement whereby I need to match a given point (lat,lon) against several polygons to decide if there is a match. The easiest way would be to iterative over each polygon and apply the point-in-polygon check algorithm, but that is prohibitively expensive. The next optimization that I did was to define a bounding rectangle for each polygon (upper bound, lower bound) and iteratively check the point against the bounding box (fewer comparisons as against checking all the points in the polygon). Is there any other optimization possible? Would a spatial index on the bound rectangle points or a geohash help ? Any guidance would be greatly appreciated. Thanks!

  • How to make a UILabel which adjusts it's text to the upper left?

    - by mystify
    For some strange reason, in iPhone OS 3.0 this doesn't work: I made a big fullscreen UILabel with numberOfLines = 0 and baselineAdjustment = UIBaselineAdjustmentNone. It refuses to show the text in the upper left. It's always in the center of the bounding box, aligned to the left. The documentation says: UIBaselineAdjustmentNone Adjust text relative to the top-left corner of the bounding box. This is the default adjustment. Available in iPhone OS 2.0 and later. Probably a framework bug? I started with shiny new labels to test it. Text is centered.

  • Master Data Management for Location Data - Oracle Site Hub

    - by david.butler(at)oracle.com
    Most MDM discussions cover key domains such as customer, supplier, product, service, and reference data. It is usually understood that these domains have complex structures and hundreds if not thousands of attributes that need governing. Location, on the other hand, strikes most people as address data. How hard can that be? But for many industries, locations are complex, and site information is critical to efficient operations and relevant analytics. Retail stores and malls, bank branches, construction sites come to mind. But one of the best industries for illustrating the power of a site mastering application is Oil & Gas.   Oracle's Master Data Management solution for location data is the Oracle Site Hub. It is a location mastering solution that enables organizations to centralize site and location specific information from heterogeneous systems, creating a single view of site information that can be leveraged across all functional departments and analytical systems.   Let's take a look at the location entities the Oracle Site Hub can manage for the Oil & Gas industry: organizations, property, land, buildings, roads, oilfield, service center, inventory site, real estate, facilities, refineries, storage tanks, vendor locations, businesses, assets; project site, area, well, basin, pipelines, critical infrastructure, offshore platform, compressor station, gas station, etc. Any site can be classified into multiple hierarchies, like organizational hierarchy, operational hierarchy, geographic hierarchy, divisional hierarchies and so on. Any site can also be associated to multiple clusters, i.e. collections of sites, and these can be used as a foundation for driving reporting, analysis, organize daily work, etc. Hierarchies can also be used to model entities which are structured or non-structured collections of nodes, like for example routes, pipelines and more. The User Defined Attribute Framework provides the needed infrastructure to add single row attributes groups like well base attributes (well IDs, well type, well structure and key characterizing measures, and more) and well geometry, and multi row attribute groups like well applications, permits, production data, activities, operations, logs, treatments, tests, drills, treatments, and KPIs. Site Hub can also model areas, lands, fields, basins, pools, platforms, eco-zones, and stratigraphic layers as specific sites, tracking their base attributes, aliases, descriptions, subcomponents and more. Midstream entities (pipelines, logistic sites, pump stations) and downstream entities (cylinders, tanks, inventories, meters, partner's sites, routes, facilities, gas stations, and competitor sites) can also be easily modeled, together with their specific attributes and relationships. Site Hub can store any type of unstructured data associated to a site. This could be stored directly or on an external content management solution, like Oracle Universal Content Management. Considering a well, for example, Site Hub can store any relevant associated multimedia file such as: CAD drawings of the well profile, structure and/or parts, engineering documents, contracts, applications, permits, logs, pictures, photos, videos and more. For any site entity, Site Hub can associate all the related assets and equipments at the site, as well as all relationships between sites, between a site and multiple parties, and between a site and any purchasable or sellable item, over time. Items can be equipment, instruments, facilities, services, products, production entities, production facilities (pipelines, batteries, compressor stations, gas plants, meters, separators, etc.), support facilities (rigs, roads, transmission or radio towers, airstrips, etc.), supplier products and services, catalogs, and more. Items can just be associated to sites using standard Site Hub features, or they can be fully mastered by implementing Oracle Product Hub. Site locations (addresses or geographical coordinates) are also managed with out-of-the-box address geo-coding capabilities coupled with Google Maps integration to deliver powerful mapping capabilities and spatial data analysis. Locations can be shared between different sites. Centered on the site location, any site can also have associated areas. Site Hub can master any site location specific information, like for example cadastral, ownership, jurisdictional, geological, seismic and more, and any site-centric area specific information, like for example economical, political, risk, weather, logistic, traffic information and more. Now if anyone ever asks you why locations need MDM, think about how all these Oil & Gas entities and attributes would translate into your business locations. To learn more about Oracle's full MDM solution for the digital oil field, here is a link to Roberto Negro's outstanding whitepaper: Oracle Site Master Data Management for mastering wells and other PPDM entities in a digital oilfield context

  • Programmatically disclosing a node in af:tree and af:treeTable

    - by Frank Nimphius
    A common developer requirement when working with af:tree or af:treeTable components is to programmatically disclose (expand) a specific node in the tree. If the node to disclose is not a top level node, like a location in a LocationsView -> DepartmentsView -> EmployeesView hierarchy, you need to also disclose the node's parent node hierarchy for application users to see the fully expanded tree node structure. Working on ADF Code Corner sample #101, I wrote the following code lines that show a generic option for disclosing a tree node starting from a handle to the node to disclose. The use case in ADF Coder Corner sample #101 is a drag and drop operation from a table component to a tree to relocate employees to a new department. The tree node that receives the drop is a department node contained in a location. In theory the location could be part of a country and so on to indicate the depth the tree may have. Based on this structure, the code below provides a generic solution to parse the current node parent nodes and its child nodes. The drop event provided a rowKey for the tree node that received the drop. Like in af:table, the tree row key is not of type oracle.jbo.domain.Key but an implementation of java.util.List that contains the row keys. The JUCtrlHierBinding class in the ADF Binding layer that represents the ADF tree binding at runtime provides a method named findNodeByKeyPath that allows you to get a handle to the JUCtrlHierNodeBinding instance that represents a tree node in the binding layer. CollectionModel model = (CollectionModel) your_af_tree_reference.getValue(); JUCtrlHierBinding treeBinding = (JUCtrlHierBinding ) model.getWrappedData(); JUCtrlHierNodeBinding treeDropNode = treeBinding.findNodeByKeyPath(dropRowKey); To disclose the tree node, you need to create a RowKeySet, which you do using the RowKeySetImpl class. Because the RowKeySet replaces any existing row key set in the tree, all other nodes are automatically closed. RowKeySetImpl rksImpl = new RowKeySetImpl(); //the first key to add is the node that received the drop //operation (departments).            rksImpl.add(dropRowKey);    Similar, from the tree binding, the root node can be obtained. The root node is the end of all parent node iteration and therefore important. JUCtrlHierNodeBinding rootNode = treeBinding.getRootNodeBinding(); The following code obtains a reference to the hierarchy of parent nodes until the root node is found. JUCtrlHierNodeBinding dropNodeParent = treeDropNode.getParent(); //walk up the tree to expand all parent nodes while(dropNodeParent != null && dropNodeParent != rootNode){    //add the node's keyPath (remember its a List) to the row key set    rksImpl.add(dropNodeParent.getKeyPath());      dropNodeParent = dropNodeParent.getParent(); } Next, you disclose the drop node immediate child nodes as otherwise all you see is the department node. Its not quite exactly "dinner for one", but the procedure is very similar to the one handling the parent node keys ArrayList<JUCtrlHierNodeBinding> childList = (ArrayList<JUCtrlHierNodeBinding>) treeDropNode.getChildren();                     for(JUCtrlHierNodeBinding nb : childList){   rksImpl.add(nb.getKeyPath()); } Next, the row key set is defined as the disclosed row keys on the tree so when you refresh (PPR) the tree, the new disclosed state shows tree.setDisclosedRowKeys(rksImpl); AdfFacesContext.getCurrentInstance().addPartialTarget(tree.getParent()); The refresh in my use case is on the tree parent component (a layout container), which usually shows the best effect for refreshing the tree component.

  • SD Card reader not working on Sony Vaio

    - by TessellatingHeckler
    This laptop (Sony Vaio VGN-Z31MN/B PCG-6z2m) has been installed with Windows 7 64 bit, all the drivers from Sony's VAIO site are installed, and everything in Device Manager both (a) has a driver and (b) shows as working, no exclamation marks or warnings. "Hide empty drives" in Folder options is disabled so the card reader appears, but will not read the card ("please insert a disk in drive O:"). Previously, when the laptop had Windows XP on it, it could read the same card. Also, Windows update suggested driver ("SD Card Reader") doesn't work, Ricoh own drivers install properly but do the same behaviour. Other 3rd party driver suggestions from forums (Acer and Texas-Instruments FlashMedia) do not seem to install properly. I would post the PCI id if I had it, but it was just showing up as rimsptsk\diskricohmemorystickstorage (while it had the Ricoh Driver installed).

  • Time machine disk icon on boot disk

    - by Ben Lings
    The icon for Macintosh HD (my boot disk) shows as a Time Machine disk. There is a file .com.apple.timemachine.supported in the root of the disk. If I delete the file and restart the computer, the icon goes back to a normal HD icon. However, the .com.apple.timemachine.supported file is recreated at some point on boot because when I log in again, the file has been recreated. If then reboot again, the icon goes back to being a Time Machine one. Any ideas about what is creating this file and why? More importantly - how can I get it to stop? It looks like something thinks the boot disk should be a Time Machine volume, but what? Console.app shows the following messages at approximately hourly intervals: 19/01/2010 19:23:54 /System/Library/CoreServices/backupd[7459] Starting standard backup 19/01/2010 19:23:54 /System/Library/CoreServices/backupd[7459] Cookie file is not readable or does not exist at path: /.<12 hex digits of MAC address for en0> 19/01/2010 19:23:54 /System/Library/CoreServices/backupd[7459] Volume at path / does not appear to be the correct backup volume for this computer. (Cookies do not match) 19/01/2010 19:23:59 /System/Library/CoreServices/backupd[7459] Backup failed with error: 18 Other possibly relevant information: The boot HD isn't the original - the original failed so this is a SuperDuper'd clone of the original drive. I used to use the same disk for a SuperDuper clone as for Time Machine. These are the same same symptoms as this and this.

  • Getting an error when mounting LVM snapshot

    - by Sandra
    I have migrated a file based Xen guest to LVM using dd bs=1M if=/dev/zero of=/dev/vg00/vm10 qemu-img convert ~/vm10.qcow2 -O raw /dev/vg00/vm10 and changed the Xen domain file for the VM to use the LV instead of the old file. The VM boots up, and now on the Xen host would I like to make a snapshot of the running VM. # lvcreate --size 10G --snapshot --name vm10-snapshot /dev/vg00/vm10 Logical volume "vm10-snapshot" created # mount /dev/vg00/vm10-snapshot /mnt/snapshot/ mount: you must specify the filesystem type # dmesg |tail EXT3 FS on dm-3, internal journal EXT3-fs: mounted filesystem with ordered data mode. hfs: unable to find HFS+ superblock VFS: Can't find ext3 filesystem on dev dm-4. hfs: unable to find HFS+ superblock hfs: unable to find HFS+ superblock VFS: Can't find ext3 filesystem on dev dm-2. hfs: unable to find HFS+ superblock hfs: unable to find HFS+ superblock hfs: unable to find HFS+ superblock For some reason it can't see it is an EXT3 filesystem.

  • Computer speakers receive radio station signal

    - by squircle
    I have a set of Logitech 5.1 speakers where each speaker and the source plug into the subwoofer. I'm using a Griffin Firewave with output from my MacBook Pro, and output from my custom-built desktop with a switch in the middle (built it myself out of an old Belkin A/B parallel switch). Recently, I've noticed that I can hear a local Punjabi radio station being picked up by my speakers, and the volume of this interference increases as I increase the volume of the speakers. I'm fairly sure that this radio station is at the low-end of the FM spectrum, below 90MHz (or it may be at the high end, above 105MHz, my memory isn't infallible). It gets quite annoying as I can't put my audio very loud without the interference. I've tried to put a ferrite core on the input cable just before the 3.5mm jacks plug into the subwoofer. I don't know if putting the same core around all three of the cables (green, black, orange) would negate the effects, but I'm assuming not. There has been no change. Is there any reason why this would be happening? I'm assuming the interference is coming somewhere between the FireWave and the subwoofer, because the noise gets amplified with volume increases. If anybody has any suggestions, I'd be grateful!

  • Gluster bricks are offline and errors in logs

    - by Roman Newaza
    I have substituted all the IP addresses with hostnames and renamed configs (IP to hostname) in /var/lib/glusterd by my shell script. After that I restarted Gluster Daemon and the volume. Then I checked if all the peers are connected: root@GlusterNode1a:~# gluster peer status Number of Peers: 3 Hostname: gluster-1b Uuid: 47f469e2-907a-4518-b6a4-f44878761fd2 State: Peer in Cluster (Connected) Hostname: gluster-2b Uuid: dc3a3ff7-9e30-44ac-9d15-00f9dab4d8b9 State: Peer in Cluster (Connected) Hostname: gluster-2a Uuid: 72405811-15a0-456b-86bb-1589058ff89b State: Peer in Cluster (Connected) I could see mounted volumes size change on all the nodes when I execute df command, so new data is coming. But recently I noticed error messages in app log: copy(/storage/152627/dat): failed to open stream: Structure needs cleaning readfile(/storage/1438227/dat): failed to open stream: Input/output error unlink(/storage/189457/23/dat): No such file or directory Finally, I have found out some bricks are offline: root@GlusterNode1a:~# gluster volume status Status of volume: storage Gluster process Port Online Pid ------------------------------------------------------------------------------ Brick gluster-1a:/storage/1a 24009 Y 1326 Brick gluster-1b:/storage/1b 24009 N N/A Brick gluster-2a:/storage/2a 24009 N N/A Brick gluster-2b:/storage/2b 24009 N N/A Brick gluster-1a:/storage/3a 24011 Y 1332 Brick gluster-1b:/storage/3b 24011 N N/A Brick gluster-2a:/storage/4a 24011 N N/A Brick gluster-2b:/storage/4b 24011 N N/A NFS Server on localhost 38467 Y 24670 Self-heal Daemon on localhost N/A Y 24676 NFS Server on gluster-2b 38467 Y 4339 Self-heal Daemon on gluster-2b N/A Y 4345 NFS Server on gluster-2a 38467 Y 1392 Self-heal Daemon on gluster-2a N/A Y 1402 NFS Server on gluster-1b 38467 Y 2435 Self-heal Daemon on gluster-1b N/A Y 2441 What can I do about that?

  • Keyboard's media keys are blocked by a program

    - by Mike Hanson
    I've got a Microsoft Natural Ergonomic Keyboard 4000. In addition to the regular keys, it's also got keys for Web/Home, Search, Mail, Favorites (5), Calculator, and Media functions (Mute, Volume Up/Down, and Play/Pause). Everything works most of the time, and the exception is rather odd. I use a programming system called Clarion. When that has focus, the Media keys don't work. (All the others still do.) I've also discovered that programs that I create using Clarion also block the media keys (only when they have focus). This indicates that it's probably something in Clarion's Run-Time Library (RTL) that's causing the trouble. The keys will work if I click on a non-Clarion window before hitting the media key, but that's an undesirable hassle. The odd thing is that I have many colleagues with the same keyboard, and they have no problem. When I recently upgraded from Vista Professional to Win7 Ultimate, I noticed that various things "appear" differently. For example, with my old system, when I changed the volume or muted the volume bar visualization always appeared at the bottom right on the screen. Now it doesn't appear in certain programs, even when it works. This indicates an order of precedence for visual elements. I'm fairly certain a similar order of precedence exists for keyboard hooks. Depending on how the hooks are defined, and the order in which they're applied, it would seem that sometimes the IntelliType drivers don't see the media keystrokes. The Media keys probably behave differently than the rest of the "special" keys, because they are more of a standard across all keyboards, so perhaps are handled by a different driver hooking mechanism. Does anyone have any suggestions of how I might fix this problem? Is there some way to change the order of hooks? Delay the loading of the IntelliType driver? Thanks in advance!

  • Should I persist images on EBS or S3 ??

    - by enes
    Hi; I am migrating my Java,Tomcat, Mysql server to AWS EC2. I have already attached EBS volume for storing Mysql data. In my web application people may upload images. So I should persist them. There are 2 alternatives in my mind. 1- Save uploaded images to EBS volume. 2- Use S3 service. The followings are my notes, please be skeptic about them, as my expertise is not on servers, but software development. EBS plus: S3 storage is more expensive. (0.15 $/Gb 0.1$/Gb) S3 plus: Serving statics from EBS may influence my web server's performance negatively. Is this true? Does Serving images affect server performance notably? For S3 my server will not be responsible for serving statics. S3 plus: Serving statics from EBS may result I/O cost, probably it will be minor. EBS plus: People say EBS is faster. S3 plus: People say S3 is more safe for persistence. EBS plus: No need to learn API, it is straight forward to save the images to EBS volume. Namely I can not decide, will be happy if you guide. Thanks

  • How do I configure a new (non-OS) raid device under Windows 7?

    - by GregH
    I recently installed 3 new 1TB drives in my Windows 7 (64 bit) system. These are in addition to the 10k rpm disk that I already have running the Windows 7 OS. My intent is to create a RAID 5 volume with the 3 disks. I don't seem to have a problem configuring the bios and creating the resulting 1.9 TB RAID volume. I run in to the problem when I try booting in to Windows. I get a quick flash of a blue screen and then am prompted by windows to do a repair. It tries to repair and then reboots. This sequence lasts indefinitely. If I re-configure the bios back to non-RAID (ACHI) then windows boots fine. The strange thing is that the 1.9 TB volume I configured through the bios actually shows up in windows! Strange since the motherboard is not set up with RAID. I assume that I somehow have to install the RAID drivers from the mobo manufacturer. How do I do this? Is the reason I'm getting the blue screen a result of not having the RAID drivers installed? It's strange because I can find plenty of documentation on how to set up RAID and do a fresh install Windows on to the RAID device, but nothing on how to set up a RAID device on an already running system. Advice is appreciated.
