  • Sendmail + m4 - problem converting mc files into cf

    - by zbigh
    Hi I'm currently trying to configure sendmail fo the first time and setup a mail server on a small embedded computer ( running a custom linux distribution ). I'm having an issue with the m4 macros: I'm trying to convert this: VERSIONID(`$Id: generic-linux.mc,v 8.1 1999/09/24 22:48:05 gshapiro Exp $') OSTYPE(linux)dnl DOMAIN(generic)dnl define(HELPFILE, `/etc/mail/helpfile') FEATURE(nouucp, `noscpecial') MAILER(local)dnl MAILER(smtp)dnl to sendmail.cf, but all the output I get when running m4 is: VERSIONID($Id: generic-linux.mc,v 8.1 1999/09/24 22:48:05 gshapiro Exp $) OSTYPE(linux)DOMAIN(generic) FEATURE(nouucp, noscpecial) MAILER(local)MAILER(smtp) Am I doing something wrong?

  • Converting to flash video

    - by Shadow
    I'm trying to convert a .dv video from a camcorder to flash video to show on my organization's website. I'm having issues using VLC (the file ends up empty or not compressed, depending on different options), so I either need help with VLC or other recommendations. If you're recommending software, it absolutely must be free. (My organization is non-profit) Thanks

  • How do I slow down a video generating new interpolated frames?

    - by Grzegorz Adam Hankiewicz
    I've used mencoder's speed parameter to generate a video which is played at half the speed. This basically means halving the framerate of the video. But I'm interested in software that could convert a 30fps video to another 30fps video with half the frames interpolated, maybe using the motion information stored in the video stream per se. I think this is called intra-frame interpolation, but I haven't found anything practical other than research papers. Any pointers to such software?

  • What is the best way to make an ISO file out of a DVD?

    - by Edward Tanguay
    I downloaded the huge Windows 7 .iso file and burnt it to a DVD. I then used that DVD to install Windows 7 on my machine and then realized that I the .iso file was on the Vista operating system that I replaced with Windows 7 (didn't upgrade). So now I would like to get the .iso file back but with the same key, etc. How can I convert the DVD I burned back into an .ISO file?

  • Covert wps file to PDF?

    - by Steve Folly
    I have a wps file (Microsoft Works), but no Microsoft Works, and no Microsoft Office. Ultimately, I want to get a PDF but happy to convert to an intermediate format if I can. Preferably on OS X if possible, but would use a Windows solution if there is one. Is there a converter tool I can use for this? Thanks.

  • Virtualbox, merging snapshots and base disk

    - by Henrik
    Hi, I have a virtual machine with about 30 snapshots in branches. The current development path is 22 snapshots plus the base disk. The amount of files is seemingly having an impact now on IO and the dev laptop I'm using (don't know if it is host disk performance issues with the 140GB total size over a lot of fragments, or just the fact that it is hitting sectors distributed across a lot of files). I would like to merge the current development branch of snapshots together with the base disk, but I am unsure if the following command would produce the correct outcome. I am not able to boot this disk after the procedure completes (5-6 hours). vboxmanage clonehd "C:\VPC-Storage\.VirtualBox\Machines\CRM\Snapshots\{245b27ac-e658-470a-b978-8e62137c33b1}.vhd" "E:\crm-20100624.vhd" --format VHD --type normal Could anyone confirm if this is the correct approach or not?

  • How can I set a minimum thumbnail size with ImageMagick?

    - by Zilk
    I'm trying to create thumbnails of JPG photos using ImageMagick's convert tool. The thumbnails need to have a defined size (210x159), no blank areas, and the image can be cropped if necessary. Unfortunately, I only have ImageMagick 6.3.7 available, which doesn't support the '^' geometry modifier (added in v6.3.8-3). Is there another way to achieve this in earlier versions of ImageMagick? Thanks in advance.

  • Programs for video-converting

    - by MladenB
    Is there a way to convert video, lets say, from .vob to .avi? (and to make it 'smaller', for ex. DVD 4.2 GB to .avi file of 700 MB) If it is possible, which one would you recommend, as being the best, for the Windows XP? I'm interested in some simple program, something that beginners can easily use.

  • Convert OpenGL code to DirectX

    - by Fredrik Boston Westman
    First of all, this is kind of a follow up question on @byte56 excellent anwser on this question concerning picking algorithms. I'm trying to convert one of his code examples to directX 11 however I have run into some problems ( I can pick but the picking is way off), and I wanted to make sure I had done it right before moving on and checking the rest of my code. I am not that familiar with openGl but I can imagine openGl has different coordinations systems, and functions that alters how you must implement to code a bit. The getPickRay function on the answer linked is what I'm trying to convert. This is the part of my code that I think is giving me trouble when converting from openGl to directX Because I'm unsure on how their different coordination systems differs from one another. PRVecX = ((( 2.0f * mouseX) / ClientWidth ) - 1 ) * tan((viewAngle)/2); PRVecY = (1-(( 2.0f * mouseY) / ClientHeight)) * tan((viewAngle)/2); Another thing that I am unsure about is this part: XMVECTOR worldSpaceNear = XMVector3TransformCoord(cameraSpaceNear, invMat); XMVECTOR worldSpaceFar = XMVector3TransformCoord(cameraSpaceFar, invMat); A couple of notes: The mouse coordinates are already converted so that the top left corner of the client window would be (0,0) and the bottom right (800,600) ( or whatever resolution you would have) The viewAngle is the same angle that I used when setting the camera view with XMMatrixPerspectiveFovLH. I removed the variables aspectRatio and zoomFactor because I assumed that they were related to some specific function of his game. To summarize it up to questions : Does the openGL coordination system differ in such a way that this equation in the first of my code examples wouldn't be valid when used in DirectX 11 ( with its respective screen coordination system)? Is the openGL method Matrix4f.transform(a, b, c) equal to the directX method c = XMVector3TransformCoord(b,a)? (where a is a matrix and b,c are vectors). Because I know when it comes to matrices order is important.

  • Convert a Row to a Column (or Backwards) in Google Docs Spreadsheets

    - by The Geek
    If you have to deal with a lot of spreadsheets, you’re probably really bored right now. You also might be wondering how to turn a row into a column, or a column into a row. Here’s how to do it with Google Docs Spreadsheets. If you’re an Excel user, you’re also in luck, because we’ve already shown you how to turn a row into a column, or vice-versa. It won’t make you any less bored though. Convert a Row to a Column (or backwards) The first thing you’ll need is a column or a row of information that you want to convert into the opposite. For our example, we’ve got this set of data that we created by using the Auto Fill options in Google Docs. Now in another cell, you’ll need to use the TRANSPOSE function, which you can use by simply typing in the following: =TRANSPOSE( And then selecting the cells with the mouse, or manually typing in the range of cells you want to copy. The final function in this example was: =TRANSPOSE(A1:A11) Finish it off with the final ) character to complete the function, hit the Enter key, and there we are… the column was transposed over to the right. You can use the same thing to turn columns into rows, or rows into columns—just change the range you are looking for.

  • Convert Excel File 'xls' to CSV, CAUTION: Bumps Ahead

    - by faizanahmad
    The task was to provide users with an interface where they can upload the 'csv' files, these files were to be processed and loaded to Database by a Console application. The code in Console application could not handle the 'xls' files so we thought, OK, lets convert 'xls' to 'csv' in the code, Seemed like fun. The idea was to convert it right after uploading within 'csv' file. As Microsoft does not recommend using the  Excel objects in ASP.NET, we decided to use the Jet engine to open xls. (Ace driver is used for xlsx) The code was pretty straight, can be found on following links: http://www.c-sharpcorner.com/uploadfile/yuanwang200409/102242008174401pm/1.aspx http://www.devasp.net/net/articles/display/141.html FIRST BUMP 'OleDbException (0x80004005): Unspecified error' ( Impersonation ): The ablove code ran fine in my test web site and test console application, but it gave an 'OleDbException (0x80004005): Unspecified error' in main web site, turns out imperonation was set to True and as soon as I changed it to False, it did work. on My XP box, web site was running under user                   'ASPNET'  with imperosnation set to FALSE                   'IUSR_*' i.e IIS guest user with impersonation set to TRUE The weired part was that both users had same rights on the folders I was saving files to and on Excel app in DCOM Config.  We decided to give it a try on Windows Server 2003 with web site set to windows authentication ( impersonation = true ) and yes it did work. SECOND BUMP 'External table not in correct format': I got this error with some files and it appeared that the file from client has some metadata issues  ( when I opened the file in Excel and try to save it ,excel  would give me this error saying File can not be saved in current format ) and the error was caused by that. Some people were able to reslove the error by using "Extended Properties=HTML Import;" in connection string. But it did not work for me. We decided to detour from here and use Excel object :( as we had no control on client setting the meta deta of Excel files. Before third bump there were a ouple of small thingies like 'Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80070005' Fix can be found at http://blog.crowe.co.nz/archive/2006/03/02/589.aspx THIRD BUMP ( Could not get rid of the EXCEL process  ):  I has all the code in place to 'Quiet' the excel, but, it just did not work. work around was done to Kill the process as we knew no other application on server was using EXCEL.  The normal steps to quite the excel application worked just fine in console application though.   FOURTH BUMP: Code worked with one file 1 on my machine and with the other file 2 code will break. and the same code will work perfectly fine with file 2 on some other machine . We moved it to QA  ( Windows Server 2003 )and worked with every file just perfect. But , then there was another problem: one user can upload it and second cant, permissions on folder and DCOM Conifg checked. Another Detour: Uplooad the xls as it is and convert in Console application.   Lesson Learnt:  If its 'xlsx' use 'ACE Driver' or read xml within excel as recommneded by MS. If xls and you know its always going to be properly formatted  'jet Engine'  Code: Imports Microsoft.Office.Interop Private Function ConvertFile(ByVal SourceFolder As String, ByVal FileName As String, ByVal FileExtension As String)As Boolean     Dim appExcel As New Excel.Application     Dim workBooks As Excel.Workbooks = appExcel.Workbooks     Dim objWorkbook As Excel.Workbook      Try                   objWorkbook = workBooks.Open(CompleteFilePath )                            objWorkbook.SaveAs(Filename:=CObj(SourceFolder & FileName & ".csv"), FileFormat:=Excel.XlFileFormat.xlCSV)       Catch ex As Exception         GenerateAlert(ex.Message().Replace("'", "") & " Error Converting File to CSV.")         LogError(ex )         Return False      Finally                      If Not(objWorkbook is Nothing) then               objWorkbook.Close(SaveChanges:=CObj(False))           End If           ReleaseObj(objWorkbook)                                      ReleaseObj(workBooks)           appExcel.Quit()           ReleaseObj(appExcel)                                 Dim proc As System.Diagnostics.Process           For Each proc In System.Diagnostics.Process.GetProcessesByName("EXCEL")               proc.Kill()           Next         DeleteSourceFile(SourceFolder & FileName & FileExtension)     End Try  Return True  End Function   Private Sub ReleaseObj(ByVal o As Object)     Try      System.Runtime.InteropServices.Marshal.ReleaseComObject(o)   Catch ex As Exception           LogError(ex )   Finally      o = Nothing    End Try End Sub     Protected Sub DeleteSourceFile(Byval CompleteFilePath As string)         Try             Dim MyFile As FileInfo = New FileInfo(CompleteFilePath)             If  MyFile.Exists Then                 File.Delete(CompleteFilePath)             Else              Throw New FileNotFoundException()             End If         Catch ex As Exception             GenerateAlert( " Source File could not be deleted.")              LogError(ex)         End Try     End Sub  The code to kill the process ( Avoid it if you can ): Dim proc As System.Diagnostics.Process For Each proc In System.Diagnostics.Process.GetProcessesByName("EXCEL")     proc.Kill() Next

  • overriding enumeration base type using pragma or code change

    - by vprajan
    Problem: I am using a big C/C++ code base which works on gcc & visual studio compilers where enum base type is by default 32-bit(integer type). This code also has lots of inline + embedded assembly which treats enum as integer type and enum data is used as 32-bit flags in many cases. When compiled this code with realview ARM RVCT 2.2 compiler, we started getting many issues since realview compiler decides enum base type automatically based on the value an enum is set to. http://www.keil.com/support/man/docs/armccref/armccref_Babjddhe.htm For example, Consider the below enum, enum Scale { TimesOne, //0 TimesTwo, //1 TimesFour, //2 TimesEight, //3 }; This enum is used as a 32-bit flag. but compiler optimizes it to unsigned char type for this enum. Using --enum_is_int compiler option is not a good solution for our case, since it converts all the enum's to 32-bit which will break interaction with any external code compiled without --enum_is_int. This is warning i found in RVCT compilers & Library guide, The --enum_is_int option is not recommended for general use and is not required for ISO-compatible source. Code compiled with this option is not compliant with the ABI for the ARM Architecture (base standard) [BSABI], and incorrect use might result in a failure at runtime. This option is not supported by the C++ libraries. Question How to convert all enum's base type (by hand-coded changes) to use 32-bit without affecting value ordering? enum Scale { TimesOne=0x00000000, TimesTwo, // 0x00000001 TimesFour, // 0x00000002 TimesEight, //0x00000003 }; I tried the above change. But compiler optimizes this also for our bad luck. :( There is some syntax in .NET like enum Scale: int Is this a ISO C++ standard and ARM compiler lacks it? There is no #pragma to control this enum in ARM RVCT 2.2 compiler. Is there any hidden pragma available ?

  • Rails & ActiveRecord: Appending methods to models that inherit from ActiveRecord::Base

    - by PlankTon
    I have a standard ActiveRecord model with the following: class MyModel < ActiveRecord::Base custom_method :first_field, :second_field end At the moment, that custom_method is picked up by a module sent to ActiveRecord::Base. The functionality basically works, but of course, it attaches itself to every model class, not just MyModel. So if I have MyModel and MyOtherModel in the same action, it'll assume MyOtherModel has custom_method :first_field, :second_field as well. So, my question is: How do I attach a method (eg: def custom_method(*args)) to every class that inherits from ActiveRecord::Base, but not by attaching it to ActiveRecord::Base itself? Any ideas appreciated.

  • Multi-base conversion - using all combinations for URL shortener

    - by Guffa
    I am making an URL shortener, and I am struggling with the optimal way of encoding a number (id) into a character string. I am using the characters 0-9,A-Z,a-z so it will basically be a base-62 encoding. That is pretty basic, but it doesn't make use of all possible codes. The codes that it would produce would be: 0, 1, ... y, z, 10, 11, ... zy, zz, 100, 101, ... Notice that the codes 00 to 0z is not used, the same for 000 to 0zz, and so on. I would like to use all the codes, like this: 0, 1, ... y, z, 00, 01, ... zy, zz, 000, 001, ... It would be some combination of base-62 and base-63, with different bases depending on the position... Using base-62 is easy, for example: create procedure tiny_GetCode @UrlId int as set nocount on declare @Code varchar(10) set @Code = '' while (@UrlId > 0 or len(@Code) = 0) begin set @Code = substring('0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz', @UrlId % 62 + 1, 1) + @Code set @UrlId = @UrlId / 62 end select @Code But I haven't yet managed to make a multi-base conversion out of it, to make use of all the codes.

  • Uiimport does not save variable to base workspace

    - by Tim
    I tried using uiimport to load a file to the base workspace.....It worked first time....but after trying again after a while...I wasnt seeing the variable in the base work space. I used the default variable name which is given by 'uiimport". This was the command I used: uiimport(filename) And two variables where created by default..."data" and "textdata"(which is the header)....but now when i run it is no longer saved in the base workspace I do not want to assign a variable to the uiimport like so... K = uiimport(filename) assignin(base,'green',K) I do not want to do that because My dataset has a text header and the data itself, and doing this would assign both "textdata" and "data" to "green" variable How would I be able to get the dimensions of ONLY the "data" in green and how would I pass only "data"(which is in the green variable in the workspace.."rmbr"...the green variable holds both "data" and "textdata") to another function. I was able to do all this when the uiimport automatically saved the variables in the base workspace....but somehow now it doesn't. I would appreciate any help or tips on this matter
