  • Octave: importing a large matrix in csv format

    - by Massagran
    I'm trying to import a matrix (about 80.000 rows) from a csv file to Octave. The obvious solution seems something like: load("-ascii","relative_directory/the_file.csv") or maybe renaming the file and trying: load("-ascii", "relative_directory/the_file.txt") Yet I keep getting the error: load: failed to read matrix from file "relative_directory/the_file.csv" or .txt without anymore details. Any tips are appreciated.

  • Animated transitions for jQuery UI's sortable

    - by Heilemann
    Just out of curiosity, as I haven't been able to find anything anywhere; does anyone know of a way to get jQuery UI's sortable function to animate its sorting? What I mean is, when you move an element around the sortable parent, its children, the sortables, skip around instead of smoothly animating to their new position, which besides from being an eyesore can also make it a bit difficult to figure out what has moved where. There's obviously no default option for this, but I was hoping that perhaps someone, somewhere, had a neat solution.

  • how a view controller know when it is dismissed or poped out of the navigation controller stack?

    - by Thanh-Cong Vo
    Hi all, My view controller needs to know when it is poped out of the navigation controller stack, so that it can retain itself, wait and release itself later with another notification. I intend to do like that when the view is sent dealloc message: - (void)dealloc { if (self.isPerformingSomeTask) { self.isPopedOut = YES; [self retain]; return; } [super dealloc]; } But I think this is not a good solution? Any idea?

  • Replacement for vsscanf on msvc

    - by ext
    Hi, I've run into an issue porting a codebase from linux (gcc) to windows (msvc). It seems like the C99 function vsscanf isn't available and has no obvious replacement. I've read about a solution using the internal function _input_l and linking statically to the crt runtime, but unfortunately I cannot link statically since it would mess with all the plugins (as dlls) being loaded by the application. So is there any replacement or a way to write a wrapper for vsscanf?

  • Capturing the overflow:auto state of a div

    - by jerrygarciuh
    Hi folks, One of the ad agencies I code for had me set up an alternate scrolling solution because you know how designers hate things that just work but aren't beautiful. So, this is married in places to their CMS. What I have not been able to sort yet is how to hide the scrolling UI when overflow:auto is not triggered by the CMS content. Any ideas? TIA JG

  • ~saas license manager

    - by Steven
    Hi all, We're developing a saas app, which is almost finished. Being in the final stages we're wondering how we are going to charge customers for using our app, how we will enforce they will not pass on their logins and so on. Does anyone know a ready-made solution? We do have a budget for this. rough criteria: - enforcing multiple payment/licensing options (trial - license with grace periods, on demand, pay per use, etc) - integration with payment providers - tracking/preventing unauthorised usage - payment/license plans adjustable on a per customer(group) basis

  • Fixing Unicode Oops

    - by Mez
    It seems that we have managed to insert into our database 2 unicode characters for each of the unicode characters we want, For example, for the unicde char 0x3CBC, we've inserted the unicode equivalents for each of it's components (0xC383 AND 0xC2BC) Can anyone think of a simple solution for fixing this? I've come up with something like SELECT replace(name, CONCAT(0xC3,0x83,0xc2,0xbc), CONCAT(0xc3,0xbc)) FROM lang For the above, but don't want to have to do this for every unicode character!

  • Is it possible to deploy a SOAP server with Axis without using WSDD?

    - by Alceu Costa
    In the project I am working I have deployed a SOAP server using Deployment Descriptors (WSDD) files. To do that a webserver (e.g tomcat, jetty) is started and then the following command is executed: java -cp %AXISCLASSPATH% org.apache.axis.client.AdminClient deploy.wsdd What I need is to skip the above command to avoid a call to the Axis AdminClient. Is it possible to deploy my webservice as war file? Note: A solution with JWS can't be used due to its limitations.

  • Is there a way in PHP to keep a file open and process each line and subsequent lines?

    - by Chris Denman
    I want to write a php script that keeps the apache_log file open and "listen" to the log and deal with each log entry as it happens. I'm thinking that I need to open a file, get the number of lines, then do this again in a loop - and when the size is different, read the new lines and process them. Am I barking up the wrong tree, or is there a silly easy solution that I have missed? Chris
