  • How to display an array's content in colomns, like ls -C does.

    - by Arko
    I wanted to display a long list of strings from an array. Right now, my script run through a for loop echoing each value to the standard output: for value in ${values[@]} do echo $value done Yeah, that's pretty ugly! And the one column listing is pretty long too... I was wondering if i can find a command or builtin helping me to display all those values in columns, like the ls command does by default when listing a directory (ls -C).

  • How can I implement a site with ASP.NET MVC without using Visual Studio?

    - by Cheeso
    I have seen ASP.NET MVC Without Visual Studio, which asks, Is it possible to produce a website based on ASP.NET MVC, without using Visual Studio? And the accepted answer is, yes. Ok, next question: how? Here's an analogy. If I want to create an ASP.NET Webforms page, I load up my favorite text editor, create a file named Something.aspx. Then I insert into that file, some boilerplate: <%@ Page Language="C#" Debug="true" Trace="false" Src="Sourcefile.cs" Inherits="My.Namespace.ContentsPage" %> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <title>Title goes here </title> <link rel="stylesheet" type="text/css" href="css/style.css"></link> <style type="text/css"> #elementid { font-size: 9pt; color: Navy; ... more css ... } </style> <script type="text/javascript" language='javascript'> // insert javascript here. </script> </head> <body> <asp:Literal Id='Holder' runat='server'/> <br/> <div id='msgs'></div> </body> </html> Then I also create the Sourcefile.cs file: namespace My.Namespace { using System; using System.Web; using System.Xml; // etc... public class ContentsPage : System.Web.UI.Page { protected System.Web.UI.WebControls.Literal Holder; void Page_Load(Object sender, EventArgs e) { // page load logic here } } } And that is a working ASPNET page, created in a text editor. Drop it into an IIS virtual directory, and it's working. What do I have to do, to make a basic, hello, World ASPNET MVC app, in a text editor? (without Visual Studio) Suppose I want a basic MVC app with a controller, one view, and a simple model. What files would I need to create, and what would go into them?

  • Dealing with wacky encodings in Python

    - by Tyson
    I have a Python script that pulls in data from many sources (databases, files, etc.). Supposedly, all the strings are unicode, but what I end up getting is any variation on the following theme (as returned by repr()): u'D\\xc3\\xa9cor' u'D\xc3\xa9cor' 'D\\xc3\\xa9cor' 'D\xc3\xa9cor' Is there a reliable way to take any four of the above strings and return the proper unicode string? u'D\xe9cor' # --> Décor The only way I can think of right now uses eval(), replace(), and a deep, burning shame that will never wash away.

  • Writing direct to disk with php

    - by Jurander
    I would like to create an upload script that doesn't fall under the php upload limit. There might be an occasion where I need to upload a 2GB, or larger file and I don't want to have to change the whole server execution to above 32MB. Is there a way to write direct to disk from php? What method might you propose someone would use to accomplish this? I have read around stack overflow but haven't quite found what I am looking to do.

  • Phonegap web view thinks device screen taller than it is - results in offscreen tabbar

    - by Stin
    I have a jQTouch application loaded via server, so all I need to do is display the webpage full screen in PhoneGap for a faux-Native app. Unfortunatley each solution I've tried in PhoneGap has an issue: it thinks the screen size is taller than it is. This resuls in the tabbar that is pinned to the bottom being permantly offscreen and there fore unusable. You should be able to recreate this with my code below and going to the iTabbar online demo. Any thoughts on how to correct this issue? For background, going to the app page in iOS safari works fine, as well as saving the page to the home screen. In both cases the webview stops at the bottom of the screen and the tabbar is therefore viewable. Also, I'm using build.phonegap.com to compile (I'm not compiling locally) I've tried two methods: load the childBrowser plugin and call up the page (with navbar hidden via options) set the following config.xml parameter to prevent phonegap from switching to Safari, and then just load the link (preferable as it's cleaner in my mind. I've pasted my index.html and config.xml below) Details on the config.xml paramater: Open all links in WebView stay-in-webview with values true or false example: <preference name="stay-in-webview" value="true" /> if set to true, all links (even with target set to blank) will open in the app's webview only use this preference if you want pages from your server to take over your entire app default is false (Source: https://build.phonegap.com/docs/config-xml) my index.html: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"> <html> <head> <meta http-equiv="Content-type" content="text/html;charset=utf-8"> <title>MyApp</title> <script src="phonegap.js"></script> </head> <body> <p><a href="http://www.itabbar.com/itabbar/demo.html#home">Launch iTabbar</a></p> </body> </html> my config.xml: <?xml version="1.0" encoding="UTF-8" ?> <widget xmlns = "http://www.w3.org/ns/widgets" xmlns:gap = "http://phonegap.com/ns/1.0" id = "com.phonegap.myapp" versionCode="10" version = "1.0.0"> <!-- versionCode is optional and Android only --> <name>MyApp</name> <description> My app is... </description> <author href="https://myurl.com" email="[email protected]"> me </author> <preference name="stay-in-webview" value="true" /> </widget>

  • jquery 1.4.1 breaks my slideshow

    - by JMC Creative
    After toying with the jquery slideshow extension, I created my own that better suited my purposes ( I didn't like that all the images needed to load at the beginning for instance). Now, upon upgrading to jQuery 1.4.2 (I know I'm late), the slideshow loads the first image fine ( from the line$('div#slideshow img#ssone').fadeIn(1500); towards the bottom), but doesn't do anything beyond that. Does anyone have any idea which jquery construct is killing my script? The live page is at lplonline.org which is using 1.3.2 for the time being. Thanks in advance. Array.prototype.random = function( r ) { var i = 0, l = this.length; if( !r ) { r = this.length; } else if( r > 0 ) { r = r % l; } else { i = r; r = l + r % l; } return this[ Math.floor( r * Math.random() - i ) ]; }; jQuery(function($){ var imgArr = new Array(); imgArr[1] = "wp-content/uploads/rotator/Brbrshop4-hrmnywkshp72006.jpg"; imgArr[2] = "wp-content/uploads/rotator/IMGA0125.JPG"; //etc, etc, about 30 of these are created dynamically from a db function randImgs () { var randImg = imgArr.random(); var img1 = $('div#slideshow img#ssone'); var img2 = $('div#slideshow img#sstwo'); if(img1.is(':visible') ) { img2.fadeIn(1500); img1.fadeOut(1500,function() { img1.attr({src : randImg}); }); } else { img1.fadeIn(1500); img2.fadeOut(1500,function() { img2.attr({src : randImg}); }); } } setInterval(randImgs,9000); // 9 SECONDS $('div#slideshow img#ssone').fadeIn(1500); }); </script> <div id="slideshow"> <img id="ssone" style="display:none;" src="wp-content/uploads/rotator/quote-investments.png" alt="" /> <img id="sstwo" style="display:none;" src="wp-content/uploads/rotator/quote-drugs.png" alt="" /> </div>

  • Programmatically access currency exchange rates

    - by Adam Pierce
    I'm setting up an online ordering system but I'm in Australia and for international customers I'd like to show prices in US dollars or Euros so they don't have to make the mental effort to convert from Australian dollars. Does anyone know if I can pull up to date exchange rates off the net somewhere in an easy-to-parse format I can access from my PHP script ? UPDATE: I have now written a PHP class which implements this. You can get the code from my website.

  • Using an image file vs data URI in the CSS

    - by fudgey
    I'm trying to decide the best way to include an image that is required for a script I've written. I discovered this site and it made me think about trying this method to include the image as a data URI since it was so small - it's a 1x1 pixel 50% opacity png file (used for a background) - it ends up at 2,792 bytes as an image versus 3,746 bytes as text in the CSS. So would this be considered good practice, or would it just clutter up the CSS unnecessarily?

  • Split a PDF by Bookmarks?

    - by Jason
    Going to be getting a single PDF that has been created by 'merging' multiple pdf's. When I view the merged PDF each single PDF is displayed as a bookmark. Is there any way to automatically split this up by bookmarks with a script? We would not know the page numbers, so that's not an option.

  • Using Constants in Perl

    - by David W.
    I am trying to define constants in Perl using the use Constant pragma: use Constant { FOO => "bar", BAR => "foo" }; I'm running into a bit of trouble, and hoping there's a standard way of handling it. First of all... I am defining a hook script for Subversion. To make things simple, I want to have a single file where the class (package) I'm using is in the same file as my actual script. Most of this package will have constants involved in it: print "This is my program"; package "MyClass"; use constant { FOO => "bar" }; sub new { yaddah, yaddah, yaddah. I would like my constant FOO to be accessible to my main program. I would like to do this without having to refer to it as MyClass::FOO. Normally, when the package is a separate file, I could do this in my main program: use MyClass qw(FOO); but, since my class and program are a single file, I can't do that. What would be the best way for my main program to be able to access my constants defined in my class? The second issue... I would like to use the constant values as hash keys: $myHash{FOO} = "bar"; The problem is that %myHash has the literal string FOO as the key and not the value of the constant. This causes problems when I do things like this: if (defined($myHash{FOO})) { print "Key " . FOO . " does exist!\n"; } I could force the context: if (defined("" . FOO . "")) { I could add parentheses: if (defined(FOO())) { Or, I could use a temporary variable: my $foo = FOO; if (defined($foo)) { None of these are really nice ways of handling this issue. So, what is the best way? Is there one way I'm missing? By the way, I don't want to use Readonly::Scalar because it is 1). slow, and 2). not part of the standard Perl package. I want to define my hook not to require additional Perl packages and to be as simple as possible to work.

  • How do I modify an attribute across all rows in a table?

    - by prgmatic
    Hi folks, My apologies for asking such a novice question but, I need help building a script using either PHP or directly in MySQL that can do the following: Take the values of a column in a table (text) Change them into capitalized words (from "this is a title" to "This Is A Title") Replace the old values (uncapitalized) with the new values (capitalized). Thanks for the help and support.
