  • Using local repository with vmbuilder and https

    - by Onitlikesonic
    I seem to be having problems using vmbuilder with a local https mirror "--mirror=https:///archive.ubuntu.com/ubuntu/" as shown below: Process (['/usr/sbin/debootstrap', '--arch=amd64', 'precise', '/tmp/tmpYc0cOktmpfs', '<my_internal_server>/ubuntu/']) returned 1. stdout: I: Retrieving Release E: Failed getting release file <my_internal_server>/ubuntu/dists/precise/Release , stderr: 2012-10-18 10:36:36,429 INFO : Unmounting tmpfs from /tmp/tmpYc0cOktmpfs Traceback (most recent call last): File "/usr/bin/vmbuilder", line 24, in <module> cli.main() File "/usr/lib/python2.7/dist-packages/VMBuilder/contrib/cli.py", line 216, in main distro.build_chroot() File "/usr/lib/python2.7/dist-packages/VMBuilder/distro.py", line 83, in build_chroot self.call_hooks('bootstrap') File "/usr/lib/python2.7/dist-packages/VMBuilder/distro.py", line 67, in call_hooks call_hooks(self, *args, **kwargs) File "/usr/lib/python2.7/dist-packages/VMBuilder/util.py", line 165, in call_hooks getattr(context, func, log_no_such_method)(*args, **kwargs) File "/usr/lib/python2.7/dist-packages/VMBuilder/plugins/ubuntu/distro.py", line 136, in bootstrap self.suite.debootstrap() File "/usr/lib/python2.7/dist-packages/VMBuilder/plugins/ubuntu/dapper.py", line 269, in debootstrap run_cmd(*cmd, **kwargs) File "/usr/lib/python2.7/dist-packages/VMBuilder/util.py", line 120, in run_cmd raise VMBuilderException, "Process (%s) returned %d. stdout: %s, stderr: %s" % (args.__repr__(), status, mystdout.buf, mystderr.buf) VMBuilder.exception.VMBuilderException: Process (['/usr/sbin/debootstrap', '--arch=amd64', 'precise', '/tmp/tmpYc0cOktmpfs', '<my_internal_server>/ubuntu/']) returned 1. stdout: I: Retrieving Release E: Failed getting release file <my_internal_server>/ubuntu/dists/precise/Release , stderr: I've checked that the files are in the correct place and i'm able to setup this using http instead of https. However this server will be providing https access only to the repos, the http is only temporarily open. This might be due to the certificate not being valid on the https (since it's self signed) or due to the fact that vmbuilder doesn't support https? In either case how can i get this to work? (If it's the case of the invalid certificate I don't mind ignoring any checks)

  • Why should main() be short?

    - by Stargazer712
    I've been programming for over 9 years, and according to the advice of my first programming teacher, I always keep my main() function extremely short. At first I had no idea why. I just obeyed without understanding, much to the delight of my professors. After gaining experience, I realized that if I designed my code correctly, having a short main() function just sortof happened. Writing modularized code and following the single responsibility principle allowed my code to be designed in "bunches", and main() served as nothing more than a catalyst to get the program running. Fast forward to a few weeks ago, I was looking at Python's souce code, and I found the main() function: /* Minimal main program -- everything is loaded from the library */ ... int main(int argc, char **argv) { ... return Py_Main(argc, argv); } Yay Python. Short main() function == Good code. Programming teachers were right. Wanting to look deeper, I took a look at Py_Main. In its entirety, it is defined as follows: /* Main program */ int Py_Main(int argc, char **argv) { int c; int sts; char *command = NULL; char *filename = NULL; char *module = NULL; FILE *fp = stdin; char *p;

  • I need to take an array of three lines in a text file and sort them base on the first line in Java.

    - by Cory
    I need to take an array of three lines in a text file and sort them base on the first line in Java. I also need to manipulate this as well and then print to screen. I have a test file that is formatted like this: 10 Michael Jackson 12 Richard Woolsey I need to input this from a text file and then rearrange it based on the number associated with the name. At that point, I need to use a random number generator and assign a variable based on the random number to each name. Then I need to print to screen the variable I added and the name in a different format. Here is an example of the output: 12: Woolsey, Richard Variable assigned 10: Jackson, Michael Other variable assigned I highly appreciate any help. I ask because I do not really know how to input the three lines as one variable and then manipulate later on in the program. Thanks, Cory

  • mpicc hangs when called from makefile; runs fine as single command

    i'm trying to compile WRF (doubt that's relevant) and am having a problem where mpicc will hang when run w/ the compile script. icc and mpif90 have no issues. the compile script is executed w/ #!/bin/csh -f just to be verbose, here's an example. i run the script and get here make[3]: Entering directory `/home/jason/wrf/wrf3.5/external/RSL_LITE' mpicc -DMPI2_SUPPORT -DMPI2_THREAD_SUPPORT -DFSEEKO64_OK -w -O3 -DDM_PARALLEL -DMAX_HISTORY=25 -DNMM_CORE=0 -c rsl_bcast.c and hang. so then i run that line by itself jason@server:~/wrf/wrf3.5$ cd /home/jason/wrf/wrf3.5/external/RSL_LITE jason@server:wrf3.5/external/RSL_LITE$ mpicc -DMPI2_SUPPORT -DMPI2_THREAD_SUPPORT -DFSEEKO64_OK -w -O3 -DDM_PARALLEL -DMAX_HISTORY=25 -DNMM_CORE=0 -c rsl_bcast.c jason@server:wrf3.5/external/RSL_LITE$ compiles instantly. starting the compile script again does the exact same thing but on the next file. i have no idea what to do, and this is basically impossible to google for.

  • .Net: What is your confident approach in "Catch" section of try-catch block, When developing CRUD op

    - by odiseh
    hi, I was wondering if there would be any confident approach for use in catch section of try-catch block when developing CRUD operations(specially when you use a Database as your data source) in .Net? well, what's your opinion about below lines? public int Insert(string name, Int32 employeeID, string createDate) { SqlConnection connection = new SqlConnection(); connection.ConnectionString = this._ConnectionString; try { SqlCommand command = connection.CreateCommand(); command.CommandType = CommandType.StoredProcedure; command.CommandText = "UnitInsert"; if (connection.State != ConnectionState.Open) connection.Open(); SqlCommandBuilder.DeriveParameters(command); command.Parameters["@Name"].Value = name; command.Parameters["@EmployeeID"].Value = employeeID; command.Parameters["@CreateDate"].Value = createDate; int i = command.ExecuteNonQuery(); command.Dispose(); return i; } catch { **// how do you "catch" any possible error here?** return 0; // } finally { connection.Close(); connection.Dispose(); connection = null; } }

  • Knowing the selections made on a 'multichooser' box in a mechanical turk hit (using Command Line Too

    - by gveda
    Hi All, I am new to Amazon Mechanical Turk, and wanted to create a hit with a qualification task. I am using the command line tools interface. One of the questions in my qualification task involves users selecting a number of options. I use a 'multichooser' selection type. Now I want to grade the responses based on the selections, where each selection has a different score. So for example, s1 has a score of 5, s2 of 10, s3 of 6, and so on. If the user selects s1 and s3, he/she gets a score of 11. Unfortunately, doing something like the following does not work: <AnswerOption> <SelectionIdentifier>s1</SelectionIdentifier> <AnswerScore>5</AnswerScore> </AnswerOption> <AnswerOption> <SelectionIdentifier>s2</SelectionIdentifier> <AnswerScore>10</AnswerScore> </AnswerOption> <AnswerOption> <SelectionIdentifier>s3</SelectionIdentifier> <AnswerScore>6</AnswerScore> </AnswerOption> If I do this, when I select multiple things, I get a score of 0. If I select only one option, say s1, then I get the appropriate score. Can you please help me on how to go about this? I could ask the same question 5 times with the same options, but then users might choose the same answer multiple times - something I wish to avoid. Thanks! Gaurav

  • Visual Studio 2010 shortcut to select word / expression / line / section / method?

    - by Lernkurve
    There is a shortcut Ctrl+Shift+W to select the entire word at the current cursor position. Is there a similar shortcut that keeps expanding the selected region every time I apply it? I mean, is there a shortcut which selects the word when applied once (same as Ctrl+Shift+W) and selects the entire line when applied twice in a row and selects the entire block when applied three times etc., i.e. keeps expanding the selected region step by step? I remember seeing such a shortcut, but I don't remember whether it was for Visual Studio or some other editor.

What's going on, is there a way to fix? fromxmlText.htmlText = theXML.contenttext; If I pull the text in from a txt file it will work fine, but taking it out of an xml file causing funky formatting. lil' help?

  • What's the reason for leaving an extra blank line at the end of a code file?

    - by Lord Torgamus
    Eclipse and MyEclipse create new Java files with an extra blank line after the last closing brace by default. I think CodeWarrior did the same thing a few years back, and that some people leave such blank lines in their code either by intention or laziness. So, this seems to be at least a moderately widespread behavior. As a former human language editor -- copy editing newspapers, mostly -- I find that those lines look like sloppiness or accidents, and I can't think of a reason to leave them in source files. I know they don't affect compilation in C-style languages, including Java. Are there benefits to having those lines, and if so, what are they?

  • How to modify/replace option set file when building from command line?

    - by Heinrich Ulbricht
    I build packages from a batch file using commands like: msbuild ..\lib\Package.dproj /target:Build /p:config=%1 The packages' settings are dependent on an option set: <Import Project="..\optionsets\COND_Defined.optset" Condition="'$(Base)'!='' And Exists('..\optionsets\COND_Defined.optset')"/> This option set defines a conditional symbol many of my packages depend on. The file looks like this: <Project xmlns="http://schemas.microsoft.com/developer/msbuild/2003"> <PropertyGroup> <DCC_Define>CONDITION;$(DCC_Define)</DCC_Define> </PropertyGroup> <ProjectExtensions> <Borland.Personality>Delphi.Personality.12</Borland.Personality> <Borland.ProjectType>OptionSet</Borland.ProjectType> <BorlandProject> <Delphi.Personality/> </BorlandProject> <ProjectFileVersion>12</ProjectFileVersion> </ProjectExtensions> </Project> Now I need two builds: one with the condition defined and one without. My attack vector would be the option set file. I have some ideas on what to do: write a program which modifies the option set file, run this before batch build fiddle with the project files and modify the option set path to contain an environment variable, then have different option sets in different locations But before starting to reinvent the wheel I'd like to ask how you would tackle this task? Maybe there are already means meant to support such a case (like certain command line switches, things I could configure in Delphi or batch file magic).

  • Python subprocess Popen.communicate() equivalent to Popen.stdout.read()?

    - by Christophe
    Very specific question (I hope): What are the differences between the following three codes? (I expect it to be only that the first does not wait for the child process to be finished, while the second and third ones do. But I need to be sure this is the only difference...) I also welcome other remarks/suggestions (though I'm already well aware of the shell=True dangers and cross-platform limitations) Note that I already read Python subprocess interaction, why does my process work with Popen.communicate, but not Popen.stdout.read()? and that I do not want/need to interact with the program after. Also note that I already read Alternatives to Python Popen.communicate() memory limitations? but that I didn't really get it... First code: from subprocess import Popen, PIPE def exe_f(command='ls -l', shell=True): "Function to execute a command and return stuff" process = Popen(command, shell=shell, stdout=PIPE, stderr=PIPE) stdout = process.stdout.read() stderr = process.stderr.read() return process, stderr, stdout Second code: from subprocess import Popen, PIPE from subprocess import communicate def exe_f(command='ls -l', shell=True): "Function to execute a command and return stuff" process = Popen(command, shell=shell, stdout=PIPE, stderr=PIPE) (stdout, stderr) = process.communicate() return process, stderr, stdout Third code: from subprocess import Popen, PIPE from subprocess import wait def exe_f(command='ls -l', shell=True): "Function to execute a command and return stuff" process = Popen(command, shell=shell, stdout=PIPE, stderr=PIPE) code = process.wait() stdout = process.stdout.read() stderr = process.stderr.read() return process, stderr, stdout Thanks.

  • Can anyone tell me what the authors mean on this line?

    - by Anirudh Goel
    i was going through this link: FAT16 Basics to Assemble Clusters. I have read the structures involved in defining a directory entry in FAT. Now when giving the example for a FAT16 File, it says the data cluster is 0x03 for the example file MyFile.txt. Which means if we logically compute the Data Cluster we will be able to reach to the first node which happens to be cluster no 3. But what I fail to understand is what the author is trying to say in the next line where it says What we can see in the File Allocation Table at this moment? How suddenly we reach to the File Allocation Table? Weren't we already there when we were going through the information of Myfile.txt? I couldn't find any reason how suddenly the author jumped to an offset location of 00000200 and is identifying the emptiness of the clusters. It will be great if someone can help me understand. Thanks
