  • Use of bit-torrent for large file download as an alternative to FTP

    - by questzen
    The company I work for procures large volumes of data and does this by subscribing to FTP locations. I was wondering if it is possible to download the same using a tracker, the major challenge is authentication of the users IMO. Most ftp servers we subscribe to have a restriction of the number of ftp connection attempts. Does any one here have any experience with this? Any advice is welcome. Edit To clarify, we subscribe to third party vendors and access their ftp location using credentials provided by them. The service is not exclusive to us, they do sell their data to several others. If we could be part of the swarm, the download rates would be pretty high without added penalty. The question is about the possibility of achieving this, so that we can put-forth a proposal in those lines. The vendors obviously wouldn't share data to non-subscribers, so that is a constraint.

  • Java: Inputting text from a file using split

    - by 00PS
    I am inputting an adjacency list for a graph. There are three columns of data (vertex, destination, edge) separated by a single space. Here is my implementation so far: FileStream in = new FileStream("input1.txt"); Scanner s = new Scanner(in); String buffer; String [] line = null; while (s.hasNext()) { buffer = s.nextLine(); line = buffer.split("\\s+"); g.add(line[0]); System.out.println("Added vertex " + line[0] + "."); g.addEdge(line[0], line[1], Integer.parseInt(line[2])); System.out.println("Added edge from " + line[0] + " to " + line[1] + " with a weight of " + Integer.parseInt(line[2]) + "."); } System.out.println("Size of graph = " + g.size()); Here is the output: Added vertex a. Added edge from a to b with a weight of 9. Exception in thread "main" java.lang.NullPointerException at structure5.GraphListDirected.addEdge(GraphListDirected.java:93) at Driver.main(Driver.java:28) I was under the impression that line = buffer.split("\\s+"); would return a 2 dimensional array of Strings to the variable line. It seemed to work the first time but not the second. Any thoughts? I would also like some feedback on my implementation of this problem. Is there a better way? Anything to help out a novice! :)

  • Windows batch file: Pipe destroys my return code

    - by murxx
    Hi, is it possible to return the errorlevel also if I pipe the output of a script into a logfile: test1.bat: call test2.bat 2>&1 | tee log.txt echo ERRORLEVEL: %ERRORLEVEL% test2.bat: exit /B 1 Output when calling test1.bat: ERRORLEVEL: 0 The errorlevel is always 0. The problem is, I want to call another script inside my script where the output should be redirected synchronously with the output shown in the command line, therefore a simple is not enough for me. I tried several ideas, but result is that the pipe always seems to destroy the given error-level... :( Can you give me any further suggestions? Thanks in advance... :)

  • Print numbers sequentially using printf with filling zeroes

    - by Werner
    Hi, in C++, using printf I want to print a sequence of number, so I get, from a "for" loop; 1 2 ... 9 10 11 and I create files from those numbers. But when I list them using "ls" I get 10 11 1 2 .. so instead of trying to solve the problem using bash, I wonder how could I print; 0001 0002 ... 0009 0010 0011 and so on Thanks

  • user buffer after doing 'write' to file opened with O_DIRECT

    - by user1868481
    I'm using the O_DIRECT flag to write to the disk directly from the user buffer. But as far as I understand, Linux doesn't guarantee that after this call, the data is written. It just writes directly from the user buffer to the physical device using DMA or anything else... Therefore, I don't understand if I can write to the user buffer after the call to 'write' function. I'm sure that example code will help to understand my question: char *user_buff = malloc(...); /* assume it is aligned as needed */ fd = open(..., O_DIRECT); write(fd, ...) memset(user_buff, 0, ...) Is the last line (memset) legal? Is writing to the user buffer valid that is maybe used by DMA to transfer data to the device?

  • Github + keep file but dont track changes

    - by Mike
    I have a codeigniter framework thats using github. Within this application I have several files that i will want to have in the repo but not track any changes on.. Example is: i deploy a new installation of this framework to a new client, i want the following files to be downloaded (they have default values 'CHANGEME') and i just have to make changes specific to this client IE(database credentials, email address info, custom css styling). // the production config files i want the files but they need to be updated to specific client needs application/config/production/config.php application/config/production/database.php application/config/production/tank_auth.php // index page, defines the environment (production|development) /index.php // all of the css/js cache (keep the folder but not the contents) /assets/cache/* // production user based styling (color, fonts etc) needs to be updated specific to client needs /assets/frontend/css/user/frontend-user.css currently if i run git clone [email protected]:user123/myRepo.git httpdocs and then i edit the files above, all is great.. until i release a hotfix or patch and run git pull. All of my changes are then overwritten.

  • How do I print this list vertically?

    - by UnworthyToast
    Let's say I have this list of asterisks, and I say it to print this way: list = ['* *', '*', '* * *', '* * * * *', '* * * * * *', '* * * *'] for i in list: print i So here, the output is: * * * * * * * * * * * * * * * * * * * * * But I want the output to be vertical, like this: * * * * * * * * * * * * * * * * * * * * * Any tips on doing this? I've tried to conceptualize how to use things like list comprehension or for-loops for this, but haven't got it quite right.

  • Maintaining file permissions across SVN updates?

    - by Mark Mayo
    I have a series of python scripts with execute permissions in Linux. They are stored in SVN. If I then run svn up to update them, the overwritten files are back to 644 - ie no execute permissions for anyone. Yes I could just script it to chmod +x * afterwards, but surely there's a way to store permissions in SVN or to maintain them when you update? Any suggestions appreciated.

  • Creating a file path in C#

    - by Jason
    So I'm trying to create a path in C#. I use Environment.Machinename and store it a variable serverName. Then I create another string variable and have some other path extension in there. Here is my code so far: string serverName = Environment.MachineName; string folderName = "\\AlarmLogger"; No matter what I do I can't seem to obtain only one backslash prior to AlarmLogger. Any ideas how I can specify a path in C#? Edit: I'm wondering if my code doesn't seem to want to paste correctly. Anyways when i paste it I only see one backslash but my code has two. Because of the escape character sequence. But something like string test = @"\" + serverName + folderName doesn't seem to want to work for me.

  • File permissions question

    - by Camran
    If I need a php-page to have access to upload images and move images from a folder on the server, what permissions would I set on the folder then? I know we have "Owner", "Group", and "Others". But what does the server (or the php-code itself) count as? Owner? Also, would I need to set the php-page with the upload script with some specific permissions to be able to upload the files? Is it execute permissions? Thanks
