  • Custom script in .screenrc

    - by benoror
    Hi. I made a script that spawns a remote shell or runs a local shell whether it's on the current machine or not: #!/bin/bash # By: benoror <[email protected]> # # spawns a remote shell or runs a local shell whether it's on the current machine or not # $1 = hostname if [ "$(hostname)" == "$1" ]; then bash else ssh "$1.local" fi For example, if I'm on server1: ./spawnshell.sh server1 -> runs bash ./spawnshell.sh server2 -> ssh to server2.local I want that script to run automatically in separate tabs in GNU Screen, but I can't make it run, my .screenrc: ... screen -t "@server1" 1 exec /home/benoror/scripts/spawnshell.sh server1 screen -t "@server2" 2 exec /home/benoror/scripts/spawnshell.sh server2 ... But it doesn't works, I've tried without 'exec', with -X option and a lot more. Any ideas ?

  • Creating a browsed history menu

    - by pundit
    Hi guys, I'm sure many of you have visited amazon.com. When you do, amazon creates a list of browsed menu items at the very bottom of the home page. I am currently doing a project that applies personalisation and customisation and wanted to implement something similar. My prototype is based on an institution, so I want to display a list of, say, the last 5 viewed programmes or courses on the home page. I am using PHP and so far i have thought of using $_SERVER["HTTP_REFERER"], but this returns only the last URL, which is not what I want. Does anyone have any suggestions to help me with this? Thanks.

  • Automatic upload of 10KB file to web service?

    - by Joseph Turian
    I am writing an application, similar to Seti@Home, that allows users to run processing on their home machine, and then upload the result to the central server. However, the final result is maybe a 10K binary file. (Processing to achieve this output is several hours.) What is the simplest reliable automatic method to upload this file to the central server? What do I need to do server-side to prevent blocking? Perhaps having the client send mail is simple and reliable? NB the client program is currently written in Python, if that matters.

  • How do I determine if my R installation on OS X has the "--enable-R-shlib" option enabled?

    - by Milktrader
    I've installed R on my OS X machine via the .pkg method. I'm trying to get a Ruby gem called RSRuby to work and though it installed correctly, it's throwing an error when I try to invoke the gem. Fatal error: R home directory is not defined Reading the documentation, R should be installed with the option --enable-R-shlib. But the R documentation states that the Mac OS X installation does this by default. How can you verify that this option is enabled on an installation if you don't know it was explicitly called during installation? I'm chasing down why RSRuby can't find R home directory and this seems like the most likely problem.

  • Scala contiguous match

    - by drypot
    pathTokens match { case List("post") => ("post", "index") case List("search") => ("search", "index") case List() => ("home", "index") } match { case (controller, action) => loadController(http, controller, action) case _ => null } I wanted contiguous match. but got compile error. :( (pathTokens match { case List("post") => ("post", "index") case List("search") => ("search", "index") case List() => ("home", "index") }) match { case (controller, action) => loadController(http, controller, action) case _ => null } When I wrapped first match with parenparenthesis, it worked ok. Why I need parenthesis here ?

  • ant - trying to copy to /lib/endorsed, library is not available in windows 7 to the next task

    - by kfox
    On Windows 7 I have an ant target that copies a xalan library into the jdk endorsed directory so that the next xslt transformation task can occur. The first time that the ant target runs, the xslt transformation fails. The second time it runs the jar file is already in the correct place and the xslt tranformation succeeds. The first time that the ant target runs, it looks like the file copied successfully. It feels like a timing issue, but I don't know what I can do to get around it. Here is my copy task: <mkdir dir="${java.home}\lib\endorsed"/> <copy file="${basedir}\xalan.jar" tofile="${java.home}\lib\endorsed\xalan.jar"/> Has anyone seen anything like this before?

  • PHP: Do we have any command via which we can delete the contents of an file without opening it.

    - by Rachel
    Is there any way to remove the contents of an file in php, do we have any php command that does that, I know unlink but I do not want to delete the file instead I just want to remove the contents of that file. I have an file which I pass while called a getCurrentDBSnap function, it takes in the file from /home/test/incoming folder and populates currentDB table state into the file using fputcsv and puts back file to /home/test/outgoing. Currently file stays in incoming folder and when I can call the function getCurrentDBSnap it would take the file and override with latest state of DB into it. Q: My question is, is it possible instead of overwriting the file, we can remove the content of file after ever getCurrentDBSnap such that file in incoming folder would be always empty ? Hope it makes sense :)

  • How to import a module from a directory?

    - by Roman
    On my system I have two versions of Python (to call them I type python and python2 in the command line). When I use the first version of Python, I cannot import sklearn module but I can do it in the second version of Python. I would like to use the first version of python (because other modules are available there) and, at the same time, I would like to be able to import sklearn from this version of Python. My solution was to use: import sys sys.path.append('location_of_the_sklearn_module') To find the location of the sklearn module I started a python session (using the second version of python, in which sklearn works). The I type: import sklearn sklearn.__file__ As a result I got: /home/name/my_name/numpy/local/lib/python2.7/site-packages/sklearn/__init__.pyc In the session of the first version of Python I tried: import sys sys.path.append('/home/name/my_name/numpy/local/lib/python2.7/site-packages/sklearn') import sklearn Unfortunately it did not work. As a result I got: ImportError: No module named sklearn Does anybody know what I am doing wrong and if it is possible to reach the goal in the way I try?

  • Loading Modules in Angular

    - by SL Dev
    I'm new to AngularJS. In my efforts to learn, I've relied on the AngularJS tutorials. Now, I'm trying to build an app using the AngularSeed project template. I'm trying to make my project as modular as possible. For that reason, my controllers are broken out into several files. Currently, I have the following: /app index.html login.html home.html javascript app.js loginCtrl.js homeCtrl.js my app.js file has the following: 'use strict'; var app = angular.module('site', ['ngRoute']); app.config(function($routeProvider, $locationProvider) { $locationProvider.html5Mode(true); $routeProvider.when('/login', {templateUrl: 'app/login.html', controller:'loginCtrl'}); $routeProvider.when('/home', {templateUrl: 'app/home.html', controller:'homeCtrl'}); $routeProvider.otherwise({redirectTo: '/login'}); }); my loginCtrl.js file is very basic at the moment. It only has: 'use strict'; app.controller('loginCtrl', function loginCtrl($scope) { } ); My homeCtrl.js is almost the same, except for the name. It looks like the following: 'use strict'; app.controller('homeCtrl', function homeCtrl($scope) { } ); My index.html file is the angularSeed index-async.html file. However, when I load the dependencies, I have the following: // load all of the dependencies asynchronously. $script([ 'http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular.min.js', 'http://ajax.googleapis.com/ajax/libs/angularjs/1.2.0-rc.3/angular-route.min.js', 'javascript/app.js', 'javascript/loginCtrl.js', 'javascript/homeCtrl.js' ], function() { // when all is done, execute bootstrap angular application angular.bootstrap(document, ['site']); }); My problem is, sometimes my app works and sometimes it doesn't. It's almost like something gets loaded before something else. Occasionally, I receive this error. Other times, I get an error in the console window that says: 'Uncaught ReferenceError: app is not defined' in loginCtrl.js. Sometimes it happens with homeCtrl.js. What am I doing wrong? It feels like I need to have my controllers in a module and pass that module in my app.config in the app.js file. However, a) I'm not sure if that allowed and b) I'm not sure how to do it.

  • Does Google crawl AJAX content?

    - by Doug
    On the home page of my site I use JQuery's ajax function to pull down a list of recent activity of users. The recent activity is displayed on the page, and each line of the recent activity includes a link to the user profile of the user who did the activity. Will Google actually make the ajax call to pull down this info and use it in calculating page relevancy / link juice flow? I'm hoping that it does not because the user profile pages are not very Google index worthy, and I don't want all those links to the User profile pages diluting my home page's link juice flow away from other more important links.

  • How to make a database service in Netbeans 6.5 to connect to SQLite databases?

    - by farzad
    I use Netbeans IDE (6.5) and I have a SQLite 2.x database. I installed a JDBC SQLite driver from zentus.com and added a new driver in Nebeans services panel. Then tried to connect to my database file from Services Databases using this URL for my database: jdbc:sqlite:/home/farzad/netbeans/myproject/mydb.sqlite but it fails to connect. I get this exception: org.netbeans.modules.db.dataview.meta.DBException: Unable to Connect to database : DatabaseConnection[name='jdbc:sqlite://home/farzad/netbeans/myproject/mydb.sqlite [ on session]'] at org.netbeans.modules.db.dataview.output.SQLExecutionHelper.initialDataLoad(SQLExecutionHelper.java:103) at org.netbeans.modules.db.dataview.output.DataView.create(DataView.java:101) at org.netbeans.modules.db.dataview.api.DataView.create(DataView.java:71) at org.netbeans.modules.db.sql.execute.SQLExecuteHelper.execute(SQLExecuteHelper.java:105) at org.netbeans.modules.db.sql.loader.SQLEditorSupport$SQLExecutor.run(SQLEditorSupport.java:480) at org.openide.util.RequestProcessor$Task.run(RequestProcessor.java:572) [catch] at org.openide.util.RequestProcessor$Processor.run(RequestProcessor.java:997) What should I do? :(

  • Ruby on Rails: building a model with an attribute not in the database?

    - by randombits
    I have a model that sets one of its attributes based off of a form parameter that a user submits. The model is a child resource to a parent resource Home. A hypothetical example is the following: A class Person has an age attribute. The user submits a birthdate as an HTTP POST parameter and from that, I need to derive the age of the user. So I'd do something like this: @home.people.build(:name => params[:name], :birthdate => params[:birthdate]) Rails would barf on that for obvious reasons, complaining it doesn't know what the attribute birthdate is. What's the proper way of going about this? Is it possible to use the build constructor with the supplied solution so that my foreign key relations are also setup properly? If not, what's a better way to work around this problem?

  • Saving CFPropertyLists To Users Folder

    - by stephen blinkhorn
    I'm trying to save a CFPropertyList to a location in the user's home folder. Using the code below I'm getting errorCode = -10 (unknown error). CFURLRef fileURL = CFURLCreateWithFileSystemPath(kCFAllocatorDefault, CFSTR("~/testfile.txt"), kCFURLPOSIXPathStyle, false ); SInt32 errorCode; Boolean status = CFURLWriteDataAndPropertiesToResource(fileURL, xmlData, NULL, &errorCode); If I change the path to something like "/testfile.txt" without the '~' then everything works. How can one save a property list to the current user's home folder? Must one obtain the user's name first and include it in the path such as /users/toffler/testfile.txt?

  • getcwd for current location based on ftp account permission

    - by John Doe
    Hello. I'm trying to make a small script that's changing the permission for specific file using a ftp connection. My problem is the absolute path. I have a ftp account wich land on the script directory (/script/). If i'm using getcwd, it will return the whole path (/home/user/public_html/script) but i need only the difference between the full path and the current path (getcwd path: /home/user/public_html/script/ ftp landing path: /script). So, how can i use getcwd to get the current directory for a ftp account? For example, if the user is landing in public_html, the path to the script will be /script/, or if he is landing inside /user, the path will be /public_html/script. Thanks

  • Kohana v2 - problem with routes

    - by yoda
    Hi, I'm attempting to set some custom routes in Kohana v2. What I'm looking for is some method that allow the system to : follow a pre-defined name to it's related root; redirect the non-matched url's into another controller; To give you a more clear view over the problem, I want the first url parameter to be associated to certain pages (contacts, home, services, about us, etc), and those urls who doesn't match the previous pages would be routed into a controller called products, in order to determine if the first url parameter regards a product name. Here's a sample of what I have : $config['_default'] = 'home'; $config['([a-zA-Z]+)'] = 'products/showcat/$1'; What am I missing here? Thanks in advance!

B stop the loop from continuing once I mouse over?

  • golang dynamically parsing files

    - by Brian Voelker
    For parsing files i have setup a variable for template.ParseFiles and i currently have to manually set each file. Two things: How would i be able to walk through a main folder and a multitude of subfolders and automatically add them to ParseFiles so i dont have to manually add each file individually? How would i be able to call a file with the same name in a subfolder because currently I get an error at runtime if i add same name file in ParseFiles. var templates = template.Must(template.ParseFiles( "index.html", // main file "subfolder/index.html" // subfolder with same filename errors on runtime "includes/header.html", "includes/footer.html", )) func main() { // Walk and ParseFiles filepath.Walk("files", func(path string, info os.FileInfo, err error) { if !info.IsDir() { // Add path to ParseFiles } return }) http.HandleFunc("/", home) http.ListenAndServe(":8080", nil) } func home(w http.ResponseWriter, r *http.Request) { render(w, "index.html") } func render(w http.ResponseWriter, tmpl string) { err := templates.ExecuteTemplate(w, tmpl, nil) if err != nil { http.Error(w, err.Error(), http.StatusInternalServerError) } }
