  • Any freeware/ideas for getting Windows 2008's backups to dump to tape after backing up to disk?

    - by TheCleaner
    I have a Windows 2008 R2 server that is being backed up to an external ISCSI drive nightly. The problem is, we'd like to use our Tape Drive (VXA 320) that Windows sees just fine to take those backups in the "WindowsImageBackup" folder and dump them to tape once a month so that we can at least have something offsite. I really don't want to go through the hassle of licensing BackupExec or similar if possible. All I'm really after is some kind of copy utility that can copy the "WindowsImageBackup" folder over to the tape drive. Ideas? P.S. If by doing this it wouldn't matter for a restore regardless, then let me know, but I would assume I could copy the folder back over to the server and then have Windows Backup find it again.

  • Duplication of Windows 7 Backup

    - by Steven Pickles
    I use the built in backup utility for Windows 7 because it's automated and flexible enough to allow me to schedule a daily shadow copy backup of particular files and folders directly to a separate internal RAID 0 array (2 x 1TB). It's also lightweight and stays out of the way. For off-site backup purposes, each week I copy the contents of the internal backup from the RAID 0 array to an external 1 TB drive. I then store move this drive to a different building. The copy from the internal backup to the external backup typically works like this: mount and erase contents of external drive highlight "file" on internal drive, hit CTRL+C CTRL+V on root directory of external drive Is there a better way to synchronize? Microsoft's SyncToy application does a pitiful job, and often leaves the folders not truly synchronized... which completely defeats the ability to use the backup's restore feature.

  • rsync assigns deny permission

    - by user773478
    Currently a script is used to copy files using rsync (version 2.6.9 protocol version 29) from Linux/Unix servers to W2K3 server using very basic command such as "rsync -v source_server::share_name/file_name /cygdrive///file_name" The script further makes copy of this downloaded file for other purposes. This is part of a larger middleware that is being moved to new hardware on W2K8R2 Second part of making copy of the file does not work using more recent rsync client version 3.0.7 protocol version 30 (shows up as cwRsync in add/remove programs) Reason being rsync assigns special permissions to file that includes deny. The user (service account) which downloads the file is in local admin group. The file can be copied elsewhere using rsync. It can be deleted. But cannot be opened or copied locally by same user as deny permission supersedes.

  • Transferring to a SSD using Windows Explorer?

    - by Nick
    I've just bought a new SSD (regretting this already) which I want to make my primary hard drive on my new computer. It's a fresh Windows 8 install, so I'm wondering if I can just copy the entire contents of C: onto my new SSD drive, or will I need to copy other things too such as boot records? I don't have a CD drive unfortunately (I removed it to put in the SSD - it's a very small HTPC) and I don't have any USB stick to make a bootable copy of Clonezilla or similar. UPDATE: I have decided to re-install Windows 8 from scratch onto the SSD, the problem is obtaining the serial key that is embedded into the BIOS. I actually have a spare, unused product key from my desktop I'm writing on now, but I'd rather not use that when I already have a valid key in my new HTPC :( Thanks :)

  • VPC on Windows 7 very slow network

    - by Shigg
    I have a Windows 2003 virtual machine which I use for website testing. I've just installed Windows 7 and am using the new version VPC (not xp mode). When I try to copy a file - I need to copy some big databases across - I get a file copy speed of about 20k per sec. Copying from one PC to another on the real network transfers files at 13mb per second. Any ideas what may be causing this? I've turned off differential network compression on win 7. The Virtual HD is on a seperate physical drive to the OS. Running Windows 7 64 bit on a dual xeon with 16gb ram and 10,000 rpm drives. Tried installing VPC 2007 but windows blocks it running saying its not compatable. Many thanks for any ideas.

  • Copying large file from SD to HDD via USB failing on Ubuntu

    - by Kent Boogaart
    Hi, I'm attempting to copy some large files from my camera (Canon EOS 500D) to my laptop, which is running 64 bit Ubuntu 9.04. I am using USB to connect the two devices. For most files, it is simply a matter of control-C and control-V. I have done this successfully many times with both photos and small movies (eg. 180MB). However, when I attempt to do this with very large files (eg. 3GB), the copy seems to start with a lot of activity both on the camera and laptop, but after 10 minutes or so the camera is automatically unmounted and the copy fails to complete. I have read that this might be due to the device not mounting as a mass storage device, but I cannot see any obvious way for me to change this behavior. Can anyone offer any direction here? I'll get a USB card reader if necessary, but I'd prefer to be able to just plug my camera in. Thanks

  • Sync two external harddrives?

    - by acidzombie24
    A little mishap happened earlier today and i am thinking i should have a copy of my external harddrive since 10% of it is very valuable. What is the best solution to keep two external harddrive in sync? i'll probably use one as regular and maybe use the other only to copy data. The easiest way to keep it in sync is to clear one drive and copy the other but 1T of data will take a long time. Whats a good existing app that will keep them in sync? freeware preferred.

  • How to remove file permissions from an external hard drive?

    - by user2540416
    My macbook recently died and I am currently trying to figure out how to copy my data. What I did was, I took out the hard drive, put it in an enclosure and plugged it in to my other laptop that runs linux. The problem is, I cannot copy files from the hard drive due to file permissions. I tried to access the hard drive as root. But I still cannot copy files. How do I remove file permissions from the harddrive?

  • Python/numpy tricky slicing problem

    - by daver
    Hi stack overflow, I have a problem with some numpy stuff. I need a numpy array to behave in an unusual manner by returning a slice as a view of the data I have sliced, not a copy. So heres an example of what I want to do: Say we have a simple array like this: a = array([1, 0, 0, 0]) I would like to update consecutive entries in the array (moving left to right) with the previous entry from the array, using syntax like this: a[1:] = a[0:3] This would get the following result: a = array([1, 1, 1, 1]) Or something like this: a[1:] = 2*a[:3] # a = [1,2,4,8] To illustrate further I want the following kind of behaviour: for i in range(len(a)): if i == 0 or i+1 == len(a): continue a[i+1] = a[i] Except I want the speed of numpy. The default behavior of numpy is to take a copy of the slice, so what I actually get is this: a = array([1, 1, 0, 0]) I already have this array as a subclass of the ndarray, so I can make further changes to it if need be, I just need the slice on the right hand side to be continually updated as it updates the slice on the left hand side. Am I dreaming or is this magic possible? Update: This is all because I am trying to use Gauss-Seidel iteration to solve a linear algebra problem, more or less. It is a special case involving harmonic functions, I was trying to avoid going into this because its really not necessary and likely to confuse things further, but here goes. The algorithm is this: while not converged: for i in range(len(u[:,0])): for j in range(len(u[0,:])): # skip over boundary entries, i,j == 0 or len(u) u[i,j] = 0.25*(u[i-1,j] + u[i+1,j] + u[i, j-1] + u[i,j+1]) Right? But you can do this two ways, Jacobi involves updating each element with its neighbours without considering updates you have already made until the while loop cycles, to do it in loops you would copy the array then update one array from the copied array. However Gauss-Seidel uses information you have already updated for each of the i-1 and j-1 entries, thus no need for a copy, the loop should essentially 'know' since the array has been re-evaluated after each single element update. That is to say, every time we call up an entry like u[i-1,j] or u[i,j-1] the information calculated in the previous loop will be there. I want to replace this slow and ugly nested loop situation with one nice clean line of code using numpy slicing: u[1:-1,1:-1] = 0.25(u[:-2,1:-1] + u[2:,1:-1] + u[1:-1,:-2] + u[1:-1,2:]) But the result is Jacobi iteration because when you take a slice: u[:,-2,1:-1] you copy the data, thus the slice is not aware of any updates made. Now numpy still loops right? Its not parallel its just a faster way to loop that looks like a parallel operation in python. I want to exploit this behaviour by sort of hacking numpy to return a pointer instead of a copy when I take a slice. Right? Then every time numpy loops, that slice will 'update' or really just replicate whatever happened in the update. To do this I need slices on both sides of the array to be pointers. Anyway if there is some really really clever person out there that awesome, but I've pretty much resigned myself to believing the only answer is to loop in C.

  • Visual Studio 2010 Extension Manager (and the new VS 2010 PowerCommands Extension)

    - by ScottGu
    This is the twenty-third in a series of blog posts I’m doing on the VS 2010 and .NET 4 release. Today’s blog post covers some of the extensibility improvements made in VS 2010 – as well as a cool new "PowerCommands for Visual Studio 2010” extension that Microsoft just released (and which can be downloaded and used for free). [In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu] Extensibility in VS 2010 VS 2010 provides a much richer extensibility model than previous releases.  Anyone can build extensions that add, customize, and light-up the Visual Studio 2010 IDE, Code Editors, Project System and associated Designers. VS 2010 Extensions can be created using the new MEF (Managed Extensibility Framework) which is built-into .NET 4.  You can learn more about how to create VS 2010 extensions from this this blog post from the Visual Studio Team Blog. VS 2010 Extension Manager Developers building extensions can distribute them on their own (via their own web-sites or by selling them).  Visual Studio 2010 also now includes a built-in “Extension Manager” within the IDE that makes it much easier for developers to find, download, and enable extensions online.  You can launch the “Extension Manager” by selecting the Tools->Extension Manager menu option: This loads an “Extension Manager” dialog which accesses an “online gallery” at Microsoft, and then populates a list of available extensions that you can optionally download and enable within your copy of Visual Studio: There are already hundreds of cool extensions populated within the online gallery.  You can browse them by category (use the tree-view on the top-left to filter them).  Clicking “download” on any of the extensions will download, install, and enable it. PowerCommands for Visual Studio 2010 This weekend Microsoft released the free PowerCommands for Visual Studio 2010 extension to the online gallery.  You can learn more about it here, and download and install it via the “Extension Manager” above (search for PowerCommands to find it). The PowerCommands download adds dozens of useful commands to Visual Studio 2010.  Below is a screen-shot of just a few of the useful commands that it adds to the Solution Explorer context menus: Below is a list of all the commands included with this weekend’s PowerCommands for Visual Studio 2010 release: Enable/Disable PowerCommands in Options dialog This feature allows you to select which commands to enable in the Visual Studio IDE. Point to the Tools menu, then click Options. Expand the PowerCommands options, then click Commands. Check the commands you would like to enable. Note: All power commands are initially defaulted Enabled. Format document on save / Remove and Sort Usings on save The Format document on save option formats the tabs, spaces, and so on of the document being saved. It is equivalent to pointing to the Edit menu, clicking Advanced, and then clicking Format Document. The Remove and sort usings option removes unused using statements and sorts the remaining using statements in the document being saved. Note: The Remove and sort usings option is only available for C# documents. Format document on save and Remove and sort usings both are initially defaulted OFF. Clear All Panes This command clears all output panes. It can be executed from the button on the toolbar of the Output window. Copy Path This command copies the full path of the currently selected item to the clipboard. It can be executed by right-clicking one of these nodes in the Solution Explorer: The solution node; A project node; Any project item node; Any folder. Email CodeSnippet To email the lines of text you select in the code editor, right-click anywhere in the editor and then click Email CodeSnippet. Insert Guid Attribute This command adds a Guid attribute to a selected class. From the code editor, right-click anywhere within the class definition, then click Insert Guid Attribute. Show All Files This command shows the hidden files in all projects displayed in the Solution Explorer when the solution node is selected. It enhances the Show All Files button, which normally shows only the hidden files in the selected project node. Undo Close This command reopens a closed document , returning the cursor to its last position. To reopen the most recently closed document, point to the Edit menu, then click Undo Close. Alternately, you can use the CtrlShiftZ shortcut. To reopen any other recently closed document, point to the View menu, click Other Windows, and then click Undo Close Window. The Undo Close window appears, typically next to the Output window. Double-click any document in the list to reopen it. Collapse Projects This command collapses a project or projects in the Solution Explorer starting from the root selected node. Collapsing a project can increase the readability of the solution. This command can be executed from three different places: solution, solution folders and project nodes respectively. Copy Class This command copies a selected class entire content to the clipboard, renaming the class. This command is normally followed by a Paste Class command, which renames the class to avoid a compilation error. It can be executed from a single project item or a project item with dependent sub items. Paste Class This command pastes a class entire content from the clipboard, renaming the class to avoid a compilation error. This command is normally preceded by a Copy Class command. It can be executed from a project or folder node. Copy References This command copies a reference or set of references to the clipboard. It can be executed from the references node, a single reference node or set of reference nodes. Paste References This command pastes a reference or set of references from the clipboard. It can be executed from different places depending on the type of project. For CSharp projects it can be executed from the references node. For Visual Basic and Website projects it can be executed from the project node. Copy As Project Reference This command copies a project as a project reference to the clipboard. It can be executed from a project node. Edit Project File This command opens the MSBuild project file for a selected project inside Visual Studio. It combines the existing Unload Project and Edit Project commands. Open Containing Folder This command opens a Windows Explorer window pointing to the physical path of a selected item. It can be executed from a project item node Open Command Prompt This command opens a Visual Studio command prompt pointing to the physical path of a selected item. It can be executed from four different places: solution, project, folder and project item nodes respectively. Unload Projects This command unloads all projects in a solution. This can be useful in MSBuild scenarios when multiple projects are being edited. This command can be executed from the solution node. Reload Projects This command reloads all unloaded projects in a solution. It can be executed from the solution node. Remove and Sort Usings This command removes and sort using statements for all classes given a project. It is useful, for example, in removing or organizing the using statements generated by a wizard. This command can be executed from a solution node or a single project node. Extract Constant This command creates a constant definition statement for a selected text. Extracting a constant effectively names a literal value, which can improve readability. This command can be executed from the code editor by right-clicking selected text. Clear Recent File List This command clears the Visual Studio recent file list. The Clear Recent File List command brings up a Clear File dialog which allows any or all recent files to be selected. Clear Recent Project List This command clears the Visual Studio recent project list. The Clear Recent Project List command brings up a Clear File dialog which allows any or all recent projects to be selected. Transform Templates This command executes a custom tool with associated text templates items. It can be executed from a DSL project node or a DSL folder node. Close All This command closes all documents. It can be executed from a document tab. How to temporarily disable extensions Extensions provide a great way to make Visual Studio even more powerful, and can help improve your overall productivity.  One thing to keep in mind, though, is that extensions run within the Visual Studio process (DevEnv.exe) and so a bug within an extension can impact both the stability and performance of Visual Studio.  If you ever run into a situation where things seem slower than they should, or if you crash repeatedly, please temporarily disable any installed extensions and see if that fixes the problem.  You can do this for extensions that were installed via the online gallery by re-running the extension manager (using the Tools->Extension Manager menu option) and by selecting the “Installed Extensions” node on the top-left of the dialog – and then by clicking “Disable” on any of the extensions within your installed list: Hope this helps, Scott

  • Couldn't find package - But package is listed in the Packages file

    - by Chris
    (Quoted items are redacted elements) I am using a private repository and an currently trying to repackage some packages 3rd-party packages. I extract the package, make a few modifications (just the control files to fit with company policy - though sometimes file install locations though not in this case) and repackage (and usually rename). Normally I copy the files into a new blank debhelper project and reconstruct the package, however, with a recent one I attempting to convert and some libraries and stuff aren't linking properly (I did copy the postinst, postrm, and preinst files along with all DEDIAN files exactly), the original package worked, but my repackage doesn't, despite providing the same files in the same locations and the same postinst and preinst. So I was attempting to just modify the current packages control files (as the original package is not very good and will not list in our repository and getting a better one from the 3rd party is not an option). I also renamed the package. I did the following: dpkg-deb -R "directory" Modify DEBIAN/control dpkg-deb -b "directory" "package name I want" I did this and put it in our repository. The package shows up in the "Packages" file on the repository and running apt-get update on the client side shows the package in: /var/lib/apt/lists/"server"_"location"_Packages However when I do an apt-get install on the package name (as listed in the Packages file - I did a copy paste) it says it can't find the package. Same with an apt-cache search The Packages listings is as follow (name redacted): Package: "package name" Priority: extra Section: unknown Maintainer: "maintainer" Architecture: any Version: 1.0-lucid5 Depends: libc Filename: "directory"/"package_filename" Size: 2206292 MD5sum: "md5sum" SHA1: "sha key" SHA256: "sha256 key" Description: "description" I am running as sudo (and tried as root as well). I don't understand why apt-get won't see the package. Can you point out any flaws in what I have done, or perhaps some help on getting apt-get to properly see the package. Or perhaps an alternative. I am not even sure if this is a valid way to repackage something. Thanks.

  • Stream.CopyTo() extension method

    - by DigiMortal
    In one of my applications I needed copy data from one stream to another. After playing with streams a little bit I wrote CopyTo() extension method to Stream class you can use to copy the contents of current stream to target stream. Here is my extension method. It is my working draft and it is possible that there must be some more checks before we can say this extension method is ready to be part of some API or class library. public static void CopyTo(this Stream fromStream, Stream toStream) {     if (fromStream == null)         throw new ArgumentNullException("fromStream");     if (toStream == null)         throw new ArgumentNullException("toStream");       var bytes = new byte[8092];     int dataRead;     while ((dataRead = fromStream.Read(bytes, 0, bytes.Length)) > 0)         toStream.Write(bytes, 0, dataRead); } And here is example how to use this extension method. using(var stream = response.GetResponseStream()) using(var ms = new MemoryStream()) {     stream.CopyTo(ms);       // Do something with copied data } I am using this code to copy data from HTTP response stream to memory stream because I have to use serializer that needs more than response stream is able to offer.

  • box2d tween what am I missing

    - by philipp
    I have a Box2D project and I want to tween an kinematic body from position A, to position B. The tween function, got it from this blog: function easeInOut(t , b, c, d ){ if ( ( t /= d / 2 ) < 1){ return c/2 * t * t * t * t + b; } return -c/2 * ( (t -= 2 ) * t * t * t - 2 ) + b; } where t is the current value, b the start, c the end and d the total amount of frames (in my case). I am using the method introduced by this lesson of todd's b2d tutorials to move the body by setting its linear Velocity so here is relevant update code of the sprite: if( moveData.current == moveData.total ){ this._body.SetLinearVelocity( new b2Vec2() ); return; } var t = easeNone( moveData.current, 0, 1, moveData.total ); var step = moveData.length / moveData.total * t; var dir = moveData.direction.Copy(); //this is the line that I think might be corrected dir.Multiply( t * moveData.length * fps /moveData.total ) ; var bodyPosition = this._body.GetWorldCenter(); var idealPosition = bodyPosition.Copy(); idealPosition.Add( dir ); idealPosition.Subtract( bodyPosition.Copy() ); moveData.current++; this._body.SetLinearVelocity( idealPosition ); moveData is an Object that holds the global values of the tween, namely: current frame (int), total frames (int), the length of the total distance to travel (float) the direction vector (targetposition - bodyposition) (b2Vec2) and the start of the tween (bodyposition) (b2Vec2) Goal is to tween the body based on a fixed amount of frames: in moveData.total frames. The value of t is always between 0 and 1 and the only thing that is not working correctly is the resulting distance the body travels. I need to calculate the multiplier for the direction vector. What am I missing to make it work?? Greetings philipp

  • Hybrid USB Install Method - netboot and iso

    - by Samus Arin
    I was following the steps here ("Preparing Files for USB Memory Stick Booting") https://help.ubuntu.com/10.04/installation-guide/i386/boot-usb-files.html to create a installation usb drive for 12.1. The very first paragraph of the article states "The second is to also copy a CD image onto the USB stick and use that as a source for packages, possibly in combination with a mirror." However, the only instructions mentioned regarding an iso image is to simply copy one somewhere on the drive (after its been made bootable and syslinux, vmlinuz and initrd.gz installed/copied): "you should now copy an Ubuntu ISO image onto the stick." I thought it strange there where no configuration steps for "pointing" the kernel to the iso (like a line in syslinux.cfg or a boot: option or something), but went ahead with the install anyway. I don't think the iso was used at all, it appeared that all the OS files where downloaded during the install process. Therefore, I was wondering if anyone knew how to use this local iso image in this particular installation technique (I know the image can be installed with dd, but thats a different technique), b/c I need to reinstall (I installed unity, but it's wayy to much for my little Atom based netbook) ? Thank you.

  • Simultaneous AI in turn based games

    - by Eduard Strehlau
    I want to hack together a roguelike. Now I thought about entity and world representation and got to a quite big problem. If you want all the AI to act simultaneously you would normally(in cellular automa for examble) just copy the cell buffer and let all action of indiviual cells depend on the copy. Actions which are not valid anymore after some cell before the cell you are currently operating on changed the original enviourment(blocking the path) are just ignored or reapplied with the "current"(between turns) environment. After all cells have acted you copy the current map to the buffer again. Now for an environment with complex AI and big(datawise) entities the copying would take too long. So I thought you could put every action and entity makes into a que(make no changes to the environment) and execute the whole que after everyone took their move. Every interaction on this que are realy interacting entities, so if a entity tries to attack another entity it sends a message to it, the consequences of the attack would be visible next turn, either by just examining the entity or asking the entity for data. This would remove problems like what happens if an entity dies middle in the cue but got actions or is messaged later on(all messages would go to null, and the messages from the entity would either just be sent or deleted(haven't decided yet) But what would happen if a monster spawns a fireball which by itself tracks the player(in the same turn). Should I add the fireball to the enviourment beforehand, so make a change to the environment before executing the action list or just add the ball to the "need updated" list as a special case so it doesn't exist in the environment and still operates on it, spawing after evaluating the action list? Are there any solutions or papers on this subject which I can take a look at? EDIT: I don't need information on writing a roguelike I need information on turn based ai in respective to a complex enviourment.

  • How do I restore a backup of my keyring (containing ssh key passprases, nautilus remote filesystem passwords and wifi passwords)?

    - by con-f-use
    I changed the disk on my laptop and installed Ubuntu on the new disk. Old disk had 12.04 upgraded to 12.10 on it. Now I want to copy my old keyring with WiFi passwords, ftp passwords for nautilus and ssh key passphrases. I have the whole data from the old disk available (is now a USB disk and I did not delete the old data yet or do anything with it - I could still put it in the laptop and boot from it like nothing happend). The old methods of just copying ~/.gconf/... and ~/.gnome2/keyrings won't work. Did I miss something? 1. Edit: I figure one needs to copy files not located in the users home directory as well. I copied the whole old /home/confus (which is my home directory) to the fresh install to no effect. That whole copy is now reverted to the fresh install's home directory, so my /home/confus is as it was the after fresh install. 2. Edit: The folder /etc/NetworkManager/system-connections seems to be the place for WiFi passwords. Could be that /usr/share/keyrings is important as well for ssh keys - that's the only sensible thing that a search came up with: find /usr/ -name "*keyring* 3. Edit: Still no ssh and ftp passwords from the keyring. What I did: Convert old hard drive to usb drive Put new drive in the laptop and installed fresh version of 12.10 there Booted from old hdd via USB and copied its /etc/NetwrokManager/system-connections, ~/.gconf/ and ~/.gnome2/keyrings, ~/.ssh over to the new disk. Confirmed that all keys on the old install work Booted from new disk Result: No passphrase for ssh keys, no ftp passwords in keyring. At least the WiFi passwords are migrated.

  • Why do I get this Debug Assertion Failed? Expression: list iterator not dereferenceable [migrated]

    - by Karel
    I'm trying this example in the (translated to dutch) book of Bjarne Stroustrup (C++): #include <vector> #include <list> #include "complex.h" complex ac[200]; std::vector<complex> vc; std::list<complex> l; template<class In, class Out> void Copy(In from, In too_far, Out to) { while(from != too_far) { *to = *from; ++to; ++from; } } void g(std::vector<complex>& vc , std::list<complex>& lc) { Copy(&ac[0], &ac[200], lc.begin()); // generates debug error Copy(lc.begin(), lc.end(), vc.begin()); // also generates debug error } void f() { ac[0] = complex(10,20); g(vc, l); } int main () { f(); } ** Compiling and Linking goes successful (0 errors/warnings)** But at runtime I get this error: Debug Assertion Failed! Program: path to exe file: \program files\ms vs studio 10.0\vc\include\list Line: 207 Expression: list iterator not dereferenceable For information on how your program can cause an assertion failure, see the Visual C++ documentation on asserts.

  • Automated backups for Windows Azure SQL Database

    - by Greg Low
    One of the questions that I've often been asked is about how you can backup databases in Windows Azure SQL Database. What we have had access to was the ability to export a database to a BACPAC. A BACPAC is basically just a zip file that contains a bunch of metadata along with a set of bcp files for each of the tables in the database. Each table in the database is exported one after the other, so this does not produce a transactionally-consistent backup at a specific point in time. To get a transactionally-consistent copy, you need a database that isn't in use.The easiest way to get a database that isn't in use is to use CREATE DATABASE AS COPY OF. This creates a new database as a transactionally-consistent copy of the database that you are copying. You can then use the export options to get a consistent BACPAC created.Previously, I've had to automate this process by myself. Given there was also no SQL Agent in Azure, I used a job in my on-premises SQL Server to do this, using a linked server configuration.Now there's a much simpler way. Windows Azure SQL Database now supports an automated export function. On the Configuration tab for the database, you need to enable the Automated Export function. You can configure how often the operation is performed for you, and which storage account will be used for the backups.It's important to consider the cost impacts of this as well. You are charged for how ever many databases are on your server on a given day. So if you enable a daily backup, you will double your database costs. Do not schedule the backups just before midnight UTC, as that could cause you to have three databases each day instead of one.This is a much needed addition to the capabilities. Scott Guthrie also posted about some other notable changes today, including a preview of a new premium offering for SQL Database. In addition to the Web and Business editions, there will now be a Premium edition that has reserved (rather than shared) resources. You can read about it all in Scott's post here: http://weblogs.asp.net/scottgu/archive/2013/07/23/windows-azure-july-updates-sql-database-traffic-manager-autoscale-virtual-machines.aspx

  • Blurry printed raster images with Brother MFC-8840D

    - by Adam Monsen
    (NOTE: crossposted here: ubuntuforums.org/showthread.php?t=1621795) I've got a Brother MFC-8840D. Works great with Ubuntu server! Setting up a CUPS print server was pretty straightforward, and I also finally got network scanning working reliably with saned. Printing documents and Web pages works well: fonts are crisp/clear, etc. One issue has got me completely vexed: printing raster (ie: JPG) images. They are blurry. For example, I can scan a page of black and white text at 150 or 300 dpi. The grayscale image looks perfect on my monitor. But the printed version is much blurrier than the original, regardless of the "print resolution" dpi I choose. As a counterexample, if I use the "copy" function of the MFC-8840D, the copy looks excellent, and this function is much, much faster than if I scan then print a scan of same. I've googled around a bunch and tried different tricks (printing a PDF with the image from evince, printing with Gimp, EOG and other applications) but I just can't print anything that looks as good as a copy made with the MFC-8840D. Any ideas? I'm using Ubuntu 10.04.1 LTS server. I'm using the PPD file from solutions.brother.com. Thanks, -Adam

  • Old Lock Retrofitted for Wireless and Key-free Entry

    - by Jason Fitzpatrick
    What do you do if the old key your landlord gave you is poor fit for your apartment’s lock? If you’re the geeky sort, you build a wireless unlocking module to do the work for you. Instructables user Rybitski writes: The key to my apartment never worked quite right because it is a copy of a copy of a copy. I am fairly certain that the dead bolt is original to the building and the property manager seems to have lost the original key years ago. As a result unlocking the door was always a pain. Changing the lock wasn’t an option, but eliminating the need to use a key was. To that end, he built the device seen in the video above. An Arduino Uno drives a servo which in turn opens the deadbolt. The whole thing is controlled by a simple wireless key fob. Hit up the link below for the full build guide including code.
