  • How to echo Hyperlink Containing a Variable?

    - by John
    Hello, In the code below, I would like to make the word that prints out as the variable "$submittor" a hyperlink to "http://www...com/.../members/index.php?profile=$submittor" . I can't get it to work; I think I'm doing the formatting wrong. How can I do it? Thanks in advance, John echo '<div class="sitename3name">Submitted by '.$submittor.' on '.$dt->format('F j, Y &\nb\sp &\nb\sp g:i a').'</div>';

    I get the following message when trying to execute etherpad/bin/run-local.sh: Exception in thread "main" java.lang.NoClassDefFoundError: net/appjet/oui/main I created CLASSPATH variable, export CLASSPATH="/home/user/src/etherpad/trunk/infrastructure/build" but that didn't help either. Although I can clearly see net/appjet/oui package in the build directory.

  • Variable assignment in bash

    - by Werner
    Hi, this is probably a very stupid question; in a bash script, given the output of, for instance; awk '{print $7}' temp it gives 0.54546 I would like to give this to a variable, so I tried: read ENE <<< $(awk '{print $7}' temp) but I get Syntax error: redirection unexpected Could you tell me why, and what is the easiest way to do this assignment? Thanks

  • Stream PDF to another local App

    - by Nathan
    Hi, I'm currently trying to optimize a small firefox extension that will grab a pdf off the current document and send it to a port that another local application is listening on. Right now it uses a terrifying hackjob of cache viewer. The way I'm getting it is loading the cache, searching through it using the current URL and grabbing the file and saving it to a temp directory. Then I stream the file in, delete the temp, and send it through the socket. Now, my new design, ideally I'd want to build it from scratch and cut out saving it to the local machine at all, and just stream it through the socket. I've been looking at doing something like, //check page to ensure its a pdf //init in/out streams //stream through sock //flush Now, this would be vastly superior to the 400 line hacked up mess I have now, but I'm new to building FF extensions, and after reading a lot about URIs and the file streaming and such I'm probably more confused than when I started trying to fix this three hours ago. I'm okay with sending things through the sockets and whatnot, I understand that, I'm mainly confused about what multitude of interfaces I want to use. Gah! Thanks! Also, long time reader, first time poster!

  • node.js callback getting unexpected value for variable

    - by defrex
    I have a for loop, and inside it a variable is assigned with var. Also inside the loop a method is called which requires a callback. Inside the callback function I'm using the variable from the loop. I would expect that it's value, inside the callback function, would be the same as it was outside the callback during that iteration of the loop. However, it always seems to be the value from the last iteration of the loop. Am I misunderstanding scope in JavaScript, or is there something else wrong? The program in question here is a node.js app that will monitor a working directory for changes and restart the server when it finds one. I'll include all of the code for the curious, but the important bit is the parse_file_list function. var posix = require('posix'); var sys = require('sys'); var server; var child_js_file = process.ARGV[2]; var current_dir = __filename.split('/'); current_dir = current_dir.slice(0, current_dir.length-1).join('/'); var start_server = function(){ server = process.createChildProcess('node', [child_js_file]); server.addListener("output", function(data){sys.puts(data);}); }; var restart_server = function(){ sys.puts('change discovered, restarting server'); server.close(); start_server(); }; var parse_file_list = function(dir, files){ for (var i=0;i<files.length;i++){ var file = dir+'/'+files[i]; sys.puts('file assigned: '+file); posix.stat(file).addCallback(function(stats){ sys.puts('stats returned: '+file); if (stats.isDirectory()) posix.readdir(file).addCallback(function(files){ parse_file_list(file, files); }); else if (stats.isFile()) process.watchFile(file, restart_server); }); } }; posix.readdir(current_dir).addCallback(function(files){ parse_file_list(current_dir, files); }); start_server(); The output from this is: file assigned: /home/defrex/code/node/ejs.js file assigned: /home/defrex/code/node/templates file assigned: /home/defrex/code/node/web file assigned: /home/defrex/code/node/server.js file assigned: /home/defrex/code/node/settings.js file assigned: /home/defrex/code/node/apps file assigned: /home/defrex/code/node/dev_server.js file assigned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js stats returned: /home/defrex/code/node/main_urls.js For those from the future: node.devserver.js

  • Fortran: output format dependent on a variable

    - by Flux Capacitor
    I would like to have a FORTRAN write statement formatted to depend on some variable. For example, I could write: write(*,'(3f15.3,3f9.2)') x,y,z,(var(i),i=1,nvari) where nvari = 3 But, what if, in some cases, I actually have 4 variables (i.e. nvari = 4) I would like to write something like this: write(*,'(3f15.3,nvari(f9.2))') x,y,z,(var(i),i=1,nvari) Now, nvari can be anything and the output will work as I like. How can I make something like this work?

  • Using Reachability for Internet *or* local WiFi?

    - by randallmeadows
    I've searched SO for the answer to this question, and it's not really addressed, at least not to a point where I can make it work. I was originally only checking for Internet reachability, using: self.wwanReach = [Reachability reachabilityWithHostName:@"www.apple.com"]; [wwanReach startNotifer]; I now need to support a local WiFi connection (in the absence of reaching the Internet in general), and when I found +reachabilityForLocalWiFi, I also noticed there was +reachabilityForInternetConnection. I figured I could use these, instead of hard-coding "www.apple.com" in there, but alas, when I use self.wwanReach = [Reachability reachabilityForInternetConnection]; [wwanReach startNotifer]; self.wifiReach = [Reachability reachabilityForLocalWiFi]; [wifiReach startNotifer]; the reachability callback that I've set up "never" gets called, for values of "never" up to 10, 12, 15 minutes or so (which was as long as my patience lasted. (User's patience will be much less, I'm sure.) Switching back to +reachabilityWithHostName: works within seconds. I also tried each "pair" individually, in case there was an issue with two notifiers in progress simultaneously, but that made no difference. So: what is the appropriate way to determine reachability to either the Internet/WWAN or a local Wifi network (either one, or both)? [This particular use case is an iPhone or iPad connecting to a Mac mini computer-to-computer network; I'm sure other situations apply.]

  • Contains performs MUCH slower with variable vs constant string MS SQL Server

    - by Greg R
    For some unknown reason I'm running into a problem when passing a variable to a full text search stored procedure performs many times slower than executing the same statement with a constant value. Any idea why and how can that be avoided? This executes very fast: SELECT * FROM table WHERE CONTAINS (comments, '123') This executes very slowly and times out: DECLARE @SearchTerm nvarchar(30) SET @SearchTerm = '123' SET @SearchTerm = '"' + @SearchTerm + '"' SELECT * FROM table WHERE CONTAINS (comments, @SearchTerm) Does this make any sense???

    I have a file that looks something like this: ABC DEF GHI I have a shell variable that looks something like this: var="MRD" What I want to do, is to make my file look like this: ABC MRD DEF GHI I was trying to do this: sed -i -e 's/ABC/&$var/g' text.txt but it only inserts $var instead of the value. I also tried this: sed -i -e 's/ABC/&"$var"/g' text.txt but that didn't work either. Any thoughts? Thanks!

  • Where to store application global variable?

    - by Shawn Mclean
    I'm using silverlight, project structure is similiar to any other .net app. I have a map control that I would like to store what mode it is in (either road or aerial) so that other controls can access this. Where do I put this enum variable, I plan to use 2 way binding on it so both are updated when either changes. Thanks.

  • Setting windows powershell path variable

    - by Vasil
    So I've found out that setting the PATH environment variable affects only the old command prompt, powershell seems to have different environment settings. How do I change the environment variables for powershell (v1)? Note: I want to make my changes permanent, so I don't have to set it every time I run powershell. Does powershell have a profile file? Something like bash profile on unix?

  • SSIS global variable

    - by Pramodtech
    Is there anything similar to global variable in SSIS? I have 4 variables (FromAddress, ToAddress,...) which will be used in all packages (32). So if I can set them only once it will be very easy to use in all packages and will save my time. Please advise.
