  • Looking for fast, minimal, preferrably free disc cloning software [closed]

    - by Dave
    We have to test our application installation and functionality on many Windows operating system versions and languages (XP, Vista, Win7; English, Spanish, Portuguese, etc; 32-bit & b4-bit.) While we can do much of this in virtual machines, we have noticed that VM's sometimes hide problems, or raise false bugs. So, we need to do "bare metal" OS installation for much of our testing. I have been using Acronis True Image for the past year, and am not impressed. It often gives random errors which require a reboot, and is really slow. For example, when trying to restore an image, it goes through a "Locking partition" cycle about three times (once after you click OK on each step of the wizard), each of which can take 5 minutes to complete. This all happens BEFORE it actually starts the image copy, which is sometimes quick (3-5 minutes), sometimes long (hours). The size of all of our images are roughly the same, so that is not related. So, anyway, I'm looking to switch to something else: I only need very basic functionality--just creating images of entire discs, and then restoring those images onto the exact same hard drive at a later date. That's it. I'm not opposed to paying for a good piece of software, but if there is something free out there that does the job well, that would be a preference. My OS on which the imaging software would run is Windows Vista, but a bootable media (into a Linux flavor) would be fine also, as long as its quick to use and reliable. Recommendations? (Also, moderators, if this should be a CW, I'll be happy to mark it as such; unclear about the rules there.)

  • Eclipse - Import existing mult-rep CVS project folder

    - by iQ
    Hey guys, Wondering if anyone can help me out with eclipse in terms of importing an existing CVS managed project. I am currently trying to shift my work on to the eclipse IDE. Some details about my project and environment below. I'm working in Linux Ubuntu, the project folder is located on a mounted shared network drive, I have installed the "Eclipse CVS Client" plug-in for my version of eclipse (helios). I've tried many ways for eclipse to use my existing folder as a project and recognize the CVS data in the CVS folders. I have done the following options: Created a new project, selected existing source, located my project folder and clicked OK to finish creating. In the end the CVS files weren't automatically read. Did the same as above and after project creation I wen to the option "project menu-team-share project", it asks me to choose a repository and doesn't automatically find the CVS information in the subfolders. If your wondering I have set-up both repositories in my eclipse and can browse the repositories through the CVS browser. My project directory layout is like this: +-Project Folder (no CVS folder at this level) +---Repo A folder +-----CVS meta-info folder is INSIDE, along with all checked out files from Repo A + +---Repo B folder +-----CVS meta-info folder is INSIDE, along with all checked out files from Repo B + +-(couple of random files, not in CVS) Thanks for the help

  • Swimlane Diagram Softwares with Expand/Collapse Features

    - by louis xie
    I've been searching real hard for a software which can fulfill my needs, but to no avail. I have a swimlane diagram which is extremely huge, and almost impossible to model using Visio or any traditional swimlane software. I would need to model both the operational process, as well as the interactions within an application and between different applications. Therefore, without wasting additional effort modelling these separately, I am looking for a solution which I can combine both views together. That is, possibly one which I can expand/collapse/group/ungroup processes/subprocesses together. Take a typical credit card process for instance, a hypothetical description of the swimlane could be as such: Customer submits application form to the bank Bank Officer A receives the application form and validates that it was correctly filled Bank Officer A submits application form to Bank Officer B for processing. Bank Officer B checks credit quality of the customer through Application X. Application X submits query to Application Y to retrieve Credit Report. Application X retrieves credit report and submits to Application Z for computation of credit scores Bank Officer B validates that customer is credit worthy, and submits application to Bank Officer C for processing. The above is an over-simplified credit card request process, and a purely hypothetical one. What I'm trying to drive at is, each of the above processes have sub-processes, and I want to be able to switch between a "detailed" view and "aggregated" view. If possible, add in time dependency of the different tasks, as well. I haven't been able to find one such software which could do this.

  • How to interpolate in MatLab

    - by G Sam
    I have a 1x1 Matrix of points which specifies speed of a drive with respect to time. This speed changes throughout the operation; which means that the difference between two points is changing. To give you an example: M = [1; 2; 3; 5; 7; 9; 11; 15; 19]. (Only that this is a 892x1 matrix) I want to make this matrix twice as long (so changing the relative speed per timestep), while retaining the way the speeds change. Eg: M' = [1; 1.5; 2; 2.5; 3; 4; 5; 6; 7; 8; 9; 10; 11; 13; 15; 17; 19]. Is there an easy way to do this in MatLab? So far I have tried upsampling (which fills the time step with zeros); interp (which fills it with low-pass interpolation. Thanks!

  • Upload using python script takes very long on one laptop as compared to another

    - by Engr Am
    I have a python 2.7 code which uses STORBINARY function for uploading files to an ftp server and RETRBINARY for downloading from this server. However, the issue is the upload is taking a very long time on three laptops from different brands as compared to a Dell laptop. The strange part is when I manually upload any file, it takes the same time on all the systems. The manual upload rate and upload rate with the python script is the same on the Dell Laptop. However, on every other brand of laptop (I have tried with IBM, Toshiba, Fujitsu-Siemens) the python script has a very low upload rate than the manual attempt. Also, on all these other laptops, the upload rate using the python script is the same (1Mbit/s) while the manual upload rate is approx. 8 Mbit/s. I have tried to vary the filesize for the upload to no avail. TCP Optimizer improved the download rate on all the systems but had no effect on the upload rate. Download rate using this script on all the systems is fine and same as the manual download rate. I have checked the server and it has more than 90% free space. The network connection is the same for all the laptops, and I try uploading only with one laptop at a time. All the laptops have almost the same system configurations, same operating system and approximately the same free drive space. If anything the Dell laptop is a little less in terms of processing power and RAM than 2 of the others, but I suppose this has no effect as I have checked many times to see how much was the CPU usage and network usage during these uploads and downloads, and I am sure that no other virus or program has been eating up my bandwidth. Here is the code ('ftp' and 'file_path' are inputs to the function): path,filename=os.path.split(file_path) filesize=os.path.getsize(file_path) deffilesize=(filesize/1024)/1024 f = open(file_path, "rb") upstart = time.clock() print ftp.storbinary("STOR "+filename, f) upende = time.clock()-upstart outname="Upload " f.close() return upende, deffilesize, outname

  • How can I see which shared folders my program has access to?

    - by Kasper Hansen
    My program needs to read and write to folders on other machines that might be in another domain. So I used the System.Runtime.InteropServices to add shared folders. This worked fine when it was hard coded in the main menu of my windows service. But since then something went wrong and I don't know if it is a coding error or configuration error. What is the scope of a shared folder? If a thread in my program adds a shared folder, can the entire local machine see it? Is there a way to view what shared folders has been added? Or is there a way to see when a folder is added? [DllImport("NetApi32.dll", SetLastError = true, CharSet = CharSet.Unicode)] internal static extern System.UInt32 NetUseAdd(string UncServerName, int Level, ref USE_INFO_2 Buf, out uint ParmError); [StructLayout(LayoutKind.Sequential, CharSet = CharSet.Unicode)] internal struct USE_INFO_2 { internal LPWSTR ui2_local; internal LPWSTR ui2_remote; internal LPWSTR ui2_password; internal DWORD ui2_status; internal DWORD ui2_asg_type; internal DWORD ui2_refcount; internal DWORD ui2_usecount; internal LPWSTR ui2_username; internal LPWSTR ui2_domainname; } private void AddSharedFolder(string name, string domain, string username, string password) { if (name == null || domain == null || username == null || password == null) return; USE_INFO_2 useInfo = new USE_INFO_2(); useInfo.ui2_remote = name; useInfo.ui2_password = password; useInfo.ui2_asg_type = 0; //disk drive useInfo.ui2_usecount = 1; useInfo.ui2_username = username; useInfo.ui2_domainname = domain; uint paramErrorIndex; uint returnCode = NetUseAdd(String.Empty, 2, ref useInfo, out paramErrorIndex); if (returnCode != 0) { throw new Win32Exception((int)returnCode); } }

  • Google Translation API

    - by Nimesh
    I have text that I would like to translate into Russian. The text has custom tags and has multiple <BR> tags. The API behaves oddly with <BR> tags. Are there known issues with <BR> tags? Is there a way around it or what is the best way to use Google JQuery tranlsation to translate the text?

  • TFS How does merging work?

    - by Johannes Rudolph
    I have a release branch (RB, starting at C5) and a changeset on trunk (C10) that I now want to merge onto RB. The file has changes at C3 (common to both), one in CS 7 on RB, and one in C9 (trunk) and one in C10). So the history for my changed file looks like this: RB: C5 -> C7 Trunk: C3 -> C9 -> C10 When I merge C10 from trunk to RB, I'd expect to see a merge window showing me C10 | C3 | C7 since C3 is the common ancestor revision and C10 and C7 are the tips of my two branches respectively. However, my merge tool shows me C10 | C9 | C7. My merge tool is configured to show %1(OriginalFile)|%3(BaseFile)|%2(Modified File), so this tells me TFS chose C9 as the base revision. This is totally unexpected and completely contrary to the way I'm used to merges working in Mercurial or Git. Did I get something wrong or is TFS trying to drive me nuts with merging? Is this the default TFS Merge behavior? If so, can you provide insight into why they chose to implement it this way? I'm using TFS 2008 with VS2010 as a Client.

  • Permissions on Mac OSX

    - by Linda
    I think that this is a permissions issue but I am not sure and I am not sure how to repair the problem. I have a new MacBook. I have 2 external drives that were previously used on another MacBook. I have a lot of folders and XCode projects on the external drives. When I try to work on the projects, there is a message similar to this: "This file is not writable. You may not be able to save your changes, but you will be able to Save a Copy somewhere else. Do you want to edit this file anyway?" If I make changes and try to close the project I get this error: "The project and user files project.pbxproj and macbook.pbxuser for project “thirdtry.xcodeproj” are not writeable and cannot be saved. Your changes will be lost if you close the project. You may need to SCM edit these files to gain writability." I have tried just to rename the folder but that permission is not allowed either unless I individually change permissions for every file in an XCode project. As you can imagine, this could be time consuming for tons of files and projects. I can copy the project into internal memory and can run it then after renaming the folder that contains all of the files. This defeats the purpose of having all of the projects on an external drive. Also, in XCode, there is no "Build and Run" there is only "Build and Debug" now. I don't know if this is related or not. Suggestions for how to repair all permissions to all files and folders on my external drives? What about the "Build and Debug" and no "Build and Run" choice? Thanks, Linda

    - by user203212
    Hi, I have a dvd copied in my hard drive. It has a folder called video_ts. I am planning to run VLC player to play it. i was wondering how can I play this dvd using c#. I do not want to use a activex control inside c#. All I need to do is run the vlc.exe using process. I have already done that. But how do I select a specific file from the code that will start playig in the vlc player. My code is. System.Diagnostics.Process Proc = new System.Diagnostics.Process(); Proc.StartInfo.FileName = @"C:\Program Files\VideoLAN\VLC\vlc.exe"; Proc.StartInfo.Arguments = @"C:\Test\Legacy\VIDEO_TS\VIDEO_TS.BUP"; Proc.Start(); I am trying to send the file name as a argument to run it in the vlc.exe . But its not working. Its just opening up the vlc player. I dont want the user to select the file manually.

  • Creating a Multiwindowed Cocoa Program - Launching Procedure Suggestions?

    - by Jeffrey Kern
    I'm porting an application I developed in Visual Studio 2008 over to Cocoa. I'm currently doing a 'learn-as-you-go' approach to Cocoa, so I can experiment with different ideas and techniques in smaller, simpler projects and eventually combine them into one big application. My program logic is as follows (in a dumbed-down sense). Items in the list are mandated by my boss. Application is started 1a. Verify CD program is in drive. Verify license. If found and is valid, skip to step 7 Display license agreement. Display serial number prompt. Verify and save serial number. Hide all prior windows. Load main application window Intercept requests and commands from main application window, including making a duplicate main application window Exit program when requested by user What would the best bet be for this type of application? From another question I asked, I found out that I should keep the 'main application' window in a separate XIB file from the rest, because I might need to clone and interact with it. I know that since Cocoa and Objective-C is based off of C, there is a Main method somewhere. But what would you all suggest as a starting place for an application like this?

  • Why is the ASP.NET Repeater.Items collection empty, when controls are on the screen?

    - by Ryan
    I have an ASP page with the following repeater: <asp:Repeater runat="server" ID="RegionRepeater" DataSourceID="SqlDataSourceRegions" EnableViewState="true"> <ItemTemplate> <tr> <td valign="top"> <b><%#Eval("description")%></b> <asp:HiddenField runat="server" ID="RegionID" Value='<%#Eval("region_id")%>'/> </td> <td> <asp:FileUpload ID="FileUpload" runat="server" Width="368px" /> </td> </tr> </ItemTemplate> </asp:Repeater> (The repeater is inside a Wizard, inside a content pane). The code behind is connected to the protected void Wizard1_NextButtonClick(object sender, WizardNavigationEventArgs e) event. There are two items on the screen (two rows inside the table). However, when the code tries to read those items, the Items collection is empty! foreach(RepeaterItem region in RegionRepeater.Items) { // Never runs - the RegionRepeater.Items.Count = 0 FileUpload fileUpload = (FileUpload) region.FindControl("FileUpload"); String regionID = ((HiddenField)region.FindControl("RegionID")).Value; ... Why is the collection empty, when there are controls drawn on the screen? Thanks a lot for any help; this is starting to drive me nuts. (BTW: I tried adding/removing the EnableViewState="true" tag)

  • Domain model: should things like Logging, Audit, Persistence be in it

    - by hom.tanks
    I'm having a hard time convincing our architect that a Domain model should only have the essential elements of the business domain on it. Things like the fact that a class is persistable, that it needs logging and auditing and that it has a RESTful URI should not drive the domain model. They can be added later on, by using interfaces. Ours is a healthcare information management system. At the very coarse level, its a system where users login and access their healthcare information. They can share this information with others and be custodian for others' information (think Roles). But because of a few sound bytes that caught on early like "Everything should be a REST resource" the model now has a top level class called Resource that every other class extends from. I'm trying to make him see that the domain model should have well defined concepts like User Account, HealthDocument, UserRole etc which are distinct entities of the business , with specific associations between them. Clubbing everything under Resource class lets our model be inflexible besides being potentially incorrect. But he wants me to show him why its a bad idea to do it his way. I don't know how to articulate that properly but all my OO instincts tell me that its just not right. Any thoughts?

  • Getting 404 Not Found connecting to webDAV

    - by Cragly
    I am trying to connect to a secure webDAV folder and download a file. I am having problems just trying to get a response from the server and as it keeps giving me a 404 Not Found error as soon as I call Request.GetResponse(). I can connect to the webDAV folder using Windows Explorer by mapping a drive but cannot seem to do this in code. I have looked at other post on this site and others online but most seem to concentrate on connecting to Outlook. Has anybody else had this issue? The code I am using is as follows: string URI = "https://transfer.mycompany.com/myDirectory/myFile.csv"; string username = "username"; string password = "password"; Request = (HttpWebRequest) WebRequest.Create(URI); Request.Credentials = new NetworkCredential(username, password); Request.Method = WebRequestMethods.Http.Get; Request.Headers.Add("Translate", "f"); Response = (HttpWebResponse) Request.GetResponse(); contentLength = Convert.ToInt64(Response.GetResponseHeader("Content-Length"));

  • Sell me Distributed revision control

    - by ring bearer
    I know 1000s of similar topics floating around. I read at lest 5 threads here in SO But why am I still not convinced about DVCS? I have only following questions (note that I am selfishly worried only about Java projects) What is the advantage or value of committing locally? What? really? All modern IDEs allows you to keep track of your changes? and if required you can restore a particular change. Also, they have a feature to label your changes/versions at IDE level!? what if I crash my hard drive? where did my local repository go? (so how is it cool compared to checking in to a central repo?) Working offline or in an air plane. What is the big deal?In order for me to build a release with my changes, I must eventually connect to the central repository. Till then it does not matter how I track my changes locally. Ok Linus Torvalds gives his life to Git and hates everything else. Is that enough to blindly sing praises? Linus lives in a different world compared to offshore developers in my mid-sized project? Pitch me!

  • How to hide labels in html

    - by user225269
    I have this code which depends on this javascript from dynamic drive: http://dynamicdrive.com/dynamicindex16/formdependency.htm Its a form dependency manager. Which will show or hide elements depending on what you choose from the forms that are revealed: I don't know why but If I alter the code from this: <td> <label>ID Number<input type="checkbox" name="id" class="DEPENDS ON info BEING student"></label> </td> </tr> To this: <td> <input type="hidden" class="DEPENDS ON info BEING student"> <label style="margin-bottom: 1em; padding-bottom: 1em; border-bottom: 3px silver groove;"></label> <tr> <td> <input type="checkbox" name="id" class="DEPENDS ON info BEING student"><label>ID Number</label> </td> </tr> Note: The only change that I did here is to transfer the label from the left side of the checkbox to the right side so that they will look better. But when I do this. The labels will be visible even if I did not yet click on the button that will make it visible(but without the checkboxes). And when I click on that button, that's the only time when the checkbox will appear on the left side of the labels. The checkbox is ok, but the label is not. And the javascript is working properly. What do I do so that the checkbox and label will go together?

  • Web Deployment Project failed to map path for include virtual

    - by Duke
    I am building my site with a web deployment project but the build fails with a number of errors all relating to the "#include virtual" directives in my master page. The includes are necessary to import a set of centrally managed html template files. Here is an example of the include directive and associated error: <!-- #include virtual="/v3/sits/pdpdev/assets-templates/inc/head.html" --> /PDPRegistration.csproj/Pages/ContentPage.Master(15): error ASPPARSE: Failed to map the path '/v3/sits/pdpdev/assets-templates/inc/head.html'. The error for each included file actually appears multiple times. I'm not sure what is being mapped or why, but this was never a problem until I started using WDP (which I wanted to alter web.config depending on the build environment, among other things.) The project is built locally on my PC and then copied to the web server via a mapped drive. I found a few solutions on the 'net involving IIS metabase - they weren't quite clear to me, and I'm not sure if they apply given how I build and deploy the project (that is, would I have to build on the same system as IIS in order to make use of the metabase?) Can anyone suggest how I can get my project to build with WDP?

  • Ultra-Portable Laptop or Tablet PC for Development and Sketching

    - by Nelson LaQuet
    I am a software developer that primarily writes in PHP, [X]HTML, CSS, Javascript, C# and C++. I use Eclipse for web development, Visual Studio 2008 for C++ and C# work, TortoiseSVN, Subversion server for local repositories, SQL Server Express, Apache and MYSQL. I also use Office 2007 for word processing and spreadsheets and use Vista Ultimate 64 as my primary operating system. The only other things I do on my laptop are watch movies, surf the internet and listen to music. I currently have a Acer Aspire 5100 (1.4 GHz AMD Turion X2, 2 GB of RAM and a 15.4" screen). This thing does not cut it in performance or portability, and in addition, my DVD drive failed. And before anybody posts about vista: I have had XP Professional 32 on it for the last two years, and recently upgraded to Vista 64. It is actually faster (with areo disabled) then XP; so it is not the OS that is causing the laptop to be slow. I usually sketch a lot, for explaining things, developing user interfaces and software architecture. Because of my requirements, I was thinking about a Lenovo X61 Tablet PC. It outperforms my current laptop, is significantly more portable, and... is a tablet. My question is: do any other software developers use this (or other tablets) for programming? Does it help to be able to sketch on the computer itself? And is it capable of being a good development machine? Will it handle the above software listed? If not, what is the best ultra-portable laptop that is good for programming? Or are ultra-portable laptops even good for programming? I could manage with my 15.4" screen, but am spoiled by my two 19" at my home desktop and my job's workstation.

  • Behavior of <- NULL on lists versus data.frames for removing data

    - by Ananda Mahto
    Many R users eventually figure out lots of ways to remove elements from their data. One way is to use NULL, particularly when you want to do something like drop a column from a data.frame or drop an element from a list. Eventually, a user comes across a situation where they want to drop several columns from a data.frame at once, and they hit upon <- list(NULL) as the solution (since using <- NULL will result in an error). A data.frame is a special type of list, so it wouldn't be too tough to imagine that the approaches for removing items from a list should be the same as removing columns from a data.frame. However, they produce different results, as can be seen in the example below. ## Make some small data--two data.frames and two lists cars1 <- cars2 <- head(mtcars)[1:4] cars3 <- cars4 <- as.list(cars2) ## Demonstration that the `list(NULL)` approach works cars1[c("mpg", "cyl")] <- list(NULL) cars1 # disp hp # Mazda RX4 160 110 # Mazda RX4 Wag 160 110 # Datsun 710 108 93 # Hornet 4 Drive 258 110 # Hornet Sportabout 360 175 # Valiant 225 105 ## Demonstration that simply using `NULL` does not work cars2[c("mpg", "cyl")] <- NULL # Error in `[<-.data.frame`(`*tmp*`, c("mpg", "cyl"), value = NULL) : # replacement has 0 items, need 12 Switch to applying the same concept to a list, and compare the difference in behavior. ## Does not fully drop the items, but sets them to `NULL` cars3[c("mpg", "cyl")] <- list(NULL) # $mpg # NULL # # $cyl # NULL # # $disp # [1] 160 160 108 258 360 225 # # $hp # [1] 110 110 93 110 175 105 ## *Does* drop the `list` items while this would ## have produced an error with a `data.frame` cars4[c("mpg", "cyl")] <- NULL # $disp # [1] 160 160 108 258 360 225 # # $hp # [1] 110 110 93 110 175 105 The main questions I have are, if a data.frame is a list, why does it behave so differently in this scenario? Is there a foolproof way of knowing when an element will be dropped, when it will produce an error, and when it will simply be given a NULL value? Or do we depend on trial-and-error for this?

  • Convert Excel Range to ADO.NET DataSet or DataTable, etc.

    - by htbrady
    I have an Excel spreadsheet that will sit out on a network share drive. It needs to be accessed by my Winforms C# 3.0 application (many users could be using the app and hitting this spreadsheet at the same time). There is a lot of data on one worksheet. This data is broken out into areas that I have named as ranges. I need to be able to access these ranges individually, return each range as a dataset, and then bind it to a grid. I have found examples that use OLE and have got these to work. However, I have seen some warnings about using this method, plus at work we have been using Microsoft.Office.Interop.Excel as the standard thus far. I don't really want to stray from this unless I have to. Our users will be using Office 2003 on up as far as I know. I can get the range I need with the following code: MyDataRange = (Microsoft.Office.Interop.Excel.Range) MyWorkSheet.get_Range("MyExcelRange", Type.Missing); The OLE way was nice as it would take my first row and turn those into columns. My ranges (12 total) are for the most part different from each other in number of columns. Didn't know if this info would affect any recommendations. Is there any way to use Interop and get the returned range back into a dataset?

  • Django Development Environment Setup Questions

    - by Ross Peoples
    Hello, I'm trying to set up a good development environment for a Django project that I will be working on from two different physical locations. I have two Mac machines, one at home and one at work that I do most of my development on. I currently host a Ubuntu virtual machine on one of the machines to host the Django environemnt, install DropBox on it, and edit source code from my Mac. When I save the code file, the changes get synced over DropBox to the Ubuntu VM and the Django development server automatically restarts because of the change. This method has worked well in the past, but I am starting to use DropBox for a lot of other things now and don't want all of that to be downloaded on every virtual machine I use. Plus, I want to start using Eclipse + PyDev to be able to debug code and have code completion. Currently, I use TextEdit which is great, but doesn't support debugging or completion. So what are my options? I thought about setting up a Parallels VM on a thumb drive that has my entire environment on it (Eclipse included), but that has its own problems. Any other thoughts?

  • Loading page all content and scripts inside another

    - by Robin I Knight
    If you go to this page on our website: http://www.divethegap.com/scuba-diving-programmes-dive-the-gap/dahab-divemaster-training.html The buttons at the bottom that say 'Beginner' 'Open Water Diver' etc.... They take you to another page where you have a series of options and can book. We would like it so that rather than have to navigate to another page it loaded those options and all the scripts that make the calculations in a div on the first page. Depending on which button you press depends on which page it would load inside the div. IFrame does not work as it does not dynamically resize when the collapsible panels are opened. AJAX script at dynamic drive. http://www.dynamicdrive.com/dynamicindex17/ajaxcontent.htm does not work as none of the collapsible panels work, nor does the calculation script. How can this be done. To sum it up it would be like turning the buttons at the bottom of the page into tabs that would display the content from the pages those buttons currently link through to. Is this possible.
