  • Remove objects from different environments

    - by Fred
    I have an R script file that executes a second R script via: source("../scripts/second_file.R") That second file has the following lines: myfiles <- list.files(".",pattern = "*.csv") ... rm(myfiles) When I run the master R file I get: > source("../scripts/second_file.R") Error in file.remove(myfiles) : object 'myfiles' not found and the program aborts. I think this has something to do with the environment. I looked at ?rm() pages but less than illuminating. I figure I have to give it a position argument, but not sure which.

  • how to handle exceptions/errors in php?

    - by fayer
    when using 3rd part libraries they tend to throw exceptions to the browser and hence kill the script. eg. if im using doctrine and insert a duplicate record to the database it will throw an exception. i wonder, what is best practice for handling these exceptions. should i always do a try...catch? but doesn't that mean that i will have try...catch all over the script and for every single function/class i use? Or is it just for debugging? i don't quite get the picture. Cause if a record already exists in a database, i want to tell the user "Record already exists". And if i code a library or a function, should i always use "throw new Expcetion($message, $code)" when i want to create an error? Please shed a light on how one should create/handle exceptions/errors. Thanks

  • Care to be taken when serving static content (JS, CSS, Media) from different domain?

    - by Aahan Krish
    Let me try to explain by example. Say website is hosted at example.com (NOT www.example.com). In order to serve static content cookie-free, I've chosen to use a different domain example-static.com. Now, lets consider that my static content is currently served like this: http://example.com/js/script.js http://example.com/css/style.css http://example.com/media/image.jpg ** Now I create a CNAME record aliasing example-static.com to my main domain i.e. example.com so that the static content is served as such: http://example-static.com/js/script.js http://example-static.com/css/style.css http://example-static.com/media/image.jpg ** Is that all I have to do? Will all browsers execute JavaScript files and load web fonts without any security concerns? OR should I be using some .htaccess rules to modify header information and the like? PS: It would be great if you can provide what rules should be added, if need be.

  • Is this Javascript object literal key restriction strictly due to parsing?

    - by George Jempty
    Please refer to the code below, when I "comment in" either of the commented out lines, it causes the error (in IE) of "':' expected". So then is my conclusion correct, that this inability to provide a reference to an object value, as an object key in a string literal; is this strictly an interpreter/parsing issue? Is this a candidate for an awful (or at least "bad") "part" of Javascript, in contrast to Crockford's "good parts"? <script> var keys = {'ONE': 'one'}; //causes error: //var obj1 = {keys.ONE: 'value1'}; //var obj1 = {keys['ONE']: 'value1'}; //works var obj1 = {}; obj1[keys.ONE] = 'value1'; //also works var key_one = keys.ONE; var obj2 = {key_one: 'value1'}; </script>

  • Merge Primary Keys - Cascade Update

    - by Chris Jackson
    Is there a way to merge two primary keys into one and then cascade update all affected relationships? Here's the scenario: Customers (idCustomer int PK, Company varchar(50), etc) CustomerContacts (idCustomerContact int PK, idCustomer int FK, Name varchar(50), etc) CustomerNotes (idCustomerNote int PK, idCustomer int FK, Note Text, etc) Sometimes customers need to be merged into one. For example, you have a customer with the id of 1 and another with the id of 2. You want to merge both, so that everything that was 2 is now 1. I know I could write a script that updates all affected tables one by one, but I'd like to make it more future proof by using the cascade rules, so I don't have to update the script every time there is a new relationship added. Any ideas?

  • Why did File::Find finish short of completely traversing a large directory?

    - by Stan
    A directory exists with a total of 2,153,425 items (according to Windows folder Properties). It contains .jpg and .gif image files located within a few subdirectories. The task was to move the images into a different location while querying each file's name to retrieve some relevant info and store it elsewhere. The script that used File::Find finished at 20462 files. Out of curiosity I wrote a tiny recursive function to count the items which returned a count of 1,734,802. I suppose the difference can be accounted for by the fact that it didn't count folders, only files that passed the -f test. The problem itself can be solved differently by querying for file names first instead of traversing the directory. I'm just wondering what could've caused File::Find to finish at a small fraction of all files. The data is stored on an NTFS file system. Here is the meat of the script; I don't think including DBI stuff would be relevant since I reran the script with nothing but a counter in process_img() which returned the same number. find(\&process_img, $path_from); sub process_img { eval { return if ($_ eq "." or $_ eq ".."); ## Omitted querying and composing new paths for brevity. make_path("$path_to\\img\\$dir_area\\$dir_address\\$type"); copy($File::Find::name, "$path_to\\img\\$dir_area\\$dir_address\\$type\\$new_name"); }; if ($@) { print STDERR "eval barks: $@\n"; return } } And here is another method I used to count files: count_images($path_from); sub count_images { my $path = shift; opendir my $images, $path or die "died opening $path"; while (my $item = readdir $images) { next if $item eq '.' or $item eq '..'; $img_counter++ && next if -f "$path/$item"; count_images("$path/$item") if -d "$path/$item"; } closedir $images or die "died closing $path"; } print $img_counter;

  • Perl standard input with argument inside Bash

    - by neversaint
    I want to have such pipe in bash #! /usr/bin/bash cut -f1,2 file1.txt | myperl.pl foo | sort -u Now in myperl.pl it has content like this my $argv = $ARG[0] || "foo"; while (<>) { chomp; if ($argv eq "foo") { # do something with $_ } else { # do another } } But why the Perl script can't recognize the parameter passed through bash? Namely the code break with this message: Can't open foo: No such file or directory at myperl.pl line 15. What the right way to do it so that my Perl script can receive standard input and parameter at the same time?

  • How to properly match the following message id format in a case statement

    - by hsatterwhite
    I'm trying to get this regex pattern working in a case statement to match a particular type of ID, which could be passed to the script. I need to match the exact number of alphanumeric characters with the dashes to differentiate this message id from anything else, which may be passed to this bash script. An example of the message id format: c7c3e910-c9d2-71e1-0999-0aec446b0000 #!/bin/bash until [ -z "$1" ] do case "$1" in "") echo "No value passed" ;; [a-z0-9]\{8\}-[a-z0-9]\{4\}-[a-z0-9]\{4\}-[a-z0-9]\{4\}-[a-z0-9]\{12\}) echo "Found message ID: $1" ;; *) echo "Server $1" ;; esac shift done

  • How to stop listening on an HTTP::Daemon port in Perl

    - by Trevor
    I have a basic perl HTTP server using HTTP::Daemon. When I stop and start the script, it appears that the port is still being listened on and I get an error message saying that my HTTP::Daemon instance is undefined. If I try to start the script about a minute after it has stopped, it works fine and can bind to the port again. Is there any way to stop listening on the port when the program terminates instead of having to wait for it to timeout? use HTTP::Daemon; use HTTP::Status; my $d = new HTTP::Daemon(LocalAddr => 'localhost', LocalPort => 8000); while (my $c = $d->accept) { while (my $r = $c->get_request) { $c->send_error(RC_FORBIDDEN) } $c->close; undef($c); }

  • Ajax call not working...

    - by Probocop
    Hi, I have a form that submits to a PHP script with Jquery and Ajax. The PHP script returns some XML. For some reason the Ajax success function is not firing, and the error ones is. Can anybody see where I'm going wrong? My Jquery is as follows $('#submit-excuse').submit(function (event) { event.preventDefault(); ws_url = 'http://jacamo.epiphanydev2.co.uk/content/inc/excuse-submit.php?excuse='+$('input#excuse').val(); $.ajax({ type: 'GET', url: ws_url, dataType: "xml", beforeSend: function() { $('p#response').text('Sending.'); }, success: function(xmlIn) { results = xmlIn.getElementsByTagName("ReportID"); }, error: function() { $('p#response').text('Error.'); } }); }); And my PHP script is as follows: $excuse = $_GET['excuse']; $badwords = array ( 'one', 'two', 'three', 'four', 'five' ); if ($excuse == '') { $error = 'enter something'; } else { foreach ($badwords as $word) { $pos = strpos($excuse, $word); if($pos !== false) { $passed = false; } } if ($passed !== false) { $username = 'xxxxx'; $password = 'xxxxx'; $message = $excuse; $url = 'http://twitter.com/statuses/update.xml'; $curl_handle = curl_init(); curl_setopt($curl_handle, CURLOPT_URL, "$url"); curl_setopt($curl_handle, CURLOPT_CONNECTTIMEOUT, 2); curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl_handle, CURLOPT_POST, 1); curl_setopt($curl_handle, CURLOPT_POSTFIELDS, "status=$message"); curl_setopt($curl_handle, CURLOPT_USERPWD, "$username:$password"); $buffer = curl_exec($curl_handle); curl_close($curl_handle); $passed = 'yes'; } echo "<?xml version='1.0' encoding='UTF-8'?>\n"; echo "\t<result>\n"; echo "\t\t<passed>" . $passed .

  • Should I use DATE and TIME as fields rather than DATETIME

    - by whitstone86
    I have a project on going for a TV guide, called mytvguide in the database - I use PHPMyAdmin. This is the structure for one table, which is called tvshow1: Field Type channel varchar(255) date date No airdate time No expiration time No episode varchar(255) setreminder varchar(255) but am not sure how to get DATE, TIME to work with the pagination script (below is the script, which works for the version with DATETIME): http://pastebin.com/6S1ejAFJ However, although the DATETIME one works - it shows programmes that air on the day itself like this: Programme 1 showing on Channel 1 2:35pm "Episode 2" Set Reminder Programme 1 showing on Channel 1 May 26th - 12:50pm "Episode 3" Set Reminder Programme 1 showing on Channel 1 May 26th - 5:55pm "Episode 3" Set Reminder but I'm not quite sure how to replicate that for the fields that use DATE, TIME functions as seen above. Any advice on this is appreciated, thanks!

My question is if i can display the name of region without clicking the link "View city" but in the field "city"...is it possible to pass the webpage content (http://tinygeocoder.com/create-api.php?g=" + lat + "," + lon;) into my webpage? The content of this page is only the name as i said...no html tags! Thank you!

  • Finding files with bash and copy to another location and reducing depth of folders

    - by Kevin F
    I'm trying to recover a mates hard drive, there is no structure what so ever so music and images are everywhere but in named folders sometimes 5 folders deep, I've managed to write a one-liner that finds the files and copies them to a mounted drive but it preserves the file structure completely. What I'm after is a bit of code that searches the drive and copies to another location and copies just the parent folder with the mp3/jpg files within and not the complete path. The other issue I have is the music is /folder/folder/folder/Artist/1.mp3..2.mp3..10.mp3 etc etc so I have to preserve the folder 'Artist' to give him any hope of finding his tracks again. What I have working currently: find /media/HP/ -name *.mp3 -fprintf /media/HP/MUSIC/Script.sh 'mkdir -p "/media/HP/MUSIC/%h" \n cp "%h/%f" "/media/HP/MUSIC/%h/"\n' I then run the script.sh and it does all the copying. Many Thanks

    Hi, I have this script which loads external content: <script type="text/javascript"> var http_request = false; function makePOSTRequest(url, parameters) { http_request = false; if (window.XMLHttpRequest) { http_request = new XMLHttpRequest(); if (http_request.overrideMimeType) { http_request.overrideMimeType('text/html'); } } else if (window.ActiveXObject) { try { http_request = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { try { http_request = new ActiveXObject("Microsoft.XMLHTTP"); } catch (e) {} } } if (!http_request) { alert('Cannot create XMLHTTP instance'); return false; } http_request.onreadystatechange = alertContents; http_request.open('POST', url, true); http_request.setRequestHeader("Content-type", "application/x-www-form-urlencoded"); http_request.setRequestHeader("Content-length", parameters.length); http_request.setRequestHeader("Connection", "close"); http_request.send(parameters); } function alertContents() { if (http_request.readyState == 4) { if (http_request.status == 200) { result = http_request.responseText; document.getElementById('opciones').innerHTML = result; } else { alert('Hubo un problema con la operación.'); } } } function get(obj) { var poststr = "port_post=" + encodeURI( document.getElementById("port-post").value ); makePOSTRequest('http://www.site.com/inc/metaform.php?opcion='+ encodeURI( document.getElementById("port-post").value ), poststr); } </script> This is the select that retrieves the content: <select name="port_post" id="port-post" onchange="get(this.parentNode);"> <option value="1">Select one...</option> <option value="2">Pear</option> <option value="3">Pineapple</option> </select> And this is the container div: <div id="opciones">Default content</div> All I whish to know is how I can unset the ajax loading when I change the selection to "Select one...". I wish to say, how restoring the Default content once the "Select one..." option is selected.

  • How can I kill a Perl system call after a timeout?

    - by Fergal
    I've got a Perl script I'm using for running a file processing tool which is started using backticks. The problem is that occasionally the tool hangs and It needs to be killed in order for the rest of the files to be processed. Whats the best way best way to apply a timeout after which the parent script will kill the hung process? At the moment I'm using: foreach $file (@FILES) { $runResult = `mytool $file >> $file.log`; } But when mytool hangs after n seconds I'd like to be able to kill it and continue to the next file.

  • Changing background images like this

    - by Azzyh
    If you guys check out this webpage: http://www2.scandvision.se/oresund10/ How have they done this background fade in fade out? When i check the source this <img id="wrapper-background" src="images/body-background-0.jpg" alt="Background" /> and i think theres some kind of script maybe php or js, or both, that every 5 sec changes the background: images/body-background-1.jpg images/body-background-2.jpg images/body-background-3.jpg and so on.. So how did they do this? an example would be great, as i want to learn how to do that. If i was going to do something like this i think i would only manage to do a script in php that randomize everytime you refresh. Thank you, this will expand my knowledge
