  • bash shell date parsing, start with specifc date and loop through each day in month

    - by Joe Stein
    Hi, I need to create a bash shell script starting with a day and then loop through each subsequent day formatting that output as %Y_%m_d I figure i can submit a start day and then another param for the number of days. My issue/question is how to set a DATE (that is not now) and then add a day. so my input would be 2010_04_01 6 my output would be 2010_04_01 2010_04_02 2010_04_03 2010_04_04 2010_04_05 2010_04_06 Thanks

  • Problem with using the XPATH functions

    - by Alex
    I've got a problem with using the XPATH functions. When I try to call some functions like lower-case or upper-case etc,they are not executed and I can't figure the problem out. I included the namespace xmlns:fn="http://www.w3.org/2005/xpath-functions" at the top of my XSL stylesheet and use fn namespace to call these functions but anyway nothing is working. Can anyone explain the reason and what I should do in order to be able to use the following functions? Cheers

  • PHP - not sure how to ask - regarding variables and $_POST

    - by Phil
    I have a PHP form. The form works but I'm trying to test to see if a value other than the first item has been selected. I can't figure out how to write the If statement. $products = array( '' => 1, 'Item 2' => 2, 'Item 3' => 3, 'Item 4' => 4, 'Item 5' => 5, 'Item 6' => 6 ); $html = generateSelect('products', $products); function generateSelect($name = '', $options = array()) { $html = '<select name="'.$name.'">'; foreach ($options as $option => $value) { $html .= '<option value='.$value.'>'.$option.'</option>'; } $html .= '</select>'; return $html; } In my table, the drop down box is displayed: <tr> <td style="width:{$left_col_width}; text-align:left; vertical-align:center; padding:{$cell_padding}; font-weight:bold; {$product[3]}">{$product[0]}</td> <td style="text-align:left; vertical-align:top; padding:{$cell_padding};"><select name="{$product[1]}"> <option value="1"></option> <option value="2">Item 2</option> <option value="3">Item 3</option> <option value="4">Item 4</option> <option value="5">Item 5</option> <option value="6">Item 6</option> </select></td> </tr> I use the following if statement to check to see if someone has entered a phone number. if they have not entered a phone number, then the "Phone:" text turns red. How do I do an if statement similar to this to verify that someone has selected a product option from the drop down box? if(!empty($_POST['phone'])) { $phone[2] = clean_var($_POST['phone']); if (function_exists('htmlspecialchars')) $phone[2] = htmlspecialchars($phone[2], ENT_QUOTES); } else { $error = 1; $phone[3] = 'color:#d20128;'; } it seems simple but I can't figure it out.

  • Problem with displaying usernames in my flash[:notice] - Agile Web Development With Rails - Chapter

    - by Lee
    I can't figure out what I'm doing wrong here. I can’t seem to get the #{@user.name} to work in my flash[:notice] Everything else works just fine I can add new users, but when I add a new user instead of saying “User John Doe was successfully created”, it says “User #{@user.name} was successfully created.” I'm at this point in the depot app: depot_p/app/controllers/users_controller.rb to work.

  • How to use Split with jQuery?

    - by Matt
    I need to break apart a string that always looks like this: something -- something_else. I need to put "something_else" in another input field. Currently, this string example is being added to an HTML table row on the fly like this: tRow.append($('<td>').text($('[id$=txtEntry2]').val())); I figure "split" is the way to go but there is very little documentation that I can find yet.

  • Getting started with JUCE for Android

    - by steveha
    I need to start building an Android app that uses the JUCE libraries. I'm reading the web site and trying to figure stuff out. I tried installing JUCE on an Ubuntu 11.04 system, and when I built the IntroJucer app, the menus don't work right (they flash open when I click with the mouse but then disappear). Can a JUCE app for Android be built on Mac OS X, or even Windows? If you are using JUCE to build Android apps, please give me any advice you can.

  • Does the compiler optimize the function parameters passed by value?

    - by Naveen
    Lets say I have a function where the parameter is passed by value instead of const-reference. Further, lets assume that only the value is used inside the function i.e. the function doesn't try to modify it. In that case will the compiler will be able to figure out that it can pass the value by const-reference (for performance reasons) and generate the code accordingly? Is there any compiler which does that?

  • How to make EditText smaller than default?

    - by Heikki Toivonen
    I need to show a large number of EditText controls on a screen, each of which will only allow entering 0-2 digits. The default EditText size is too wide for me to show enough EditText controls on a screen, but I have been unable to figure out how to make them narrower. I have tried the following attributes in XML: android:maxLength="2" android:layout_width="20dip" android:maxWidth="20px" android:ems="2" android:maxEms="2". So the question is: how can EditText be made smaller than default?

  • Efficiently fetching and storing tweets from a few hundred twitter profiles?

    - by MSpreij
    The site I'm working on needs to fetch the tweets from 150-300 people, store them locally, and then list them on the front page. The profiles sit in groups. The pages will be showing the last 20 tweets (or 21-40, etc) by date, group of profiles, single profile, search, or "subject" (which is sort of a different group.. I think..) a live, context-aware tag cloud (based on the last 300 tweets of the current search, group of profiles, or single profile shown) various statistics (group stuffs, most active, etc) which depend on the type of page shown. We're expecting a fair bit of traffic. The last, similar site peaked at nearly 40K visits per day, and ran intro trouble before I started caching pages as static files, and disabling some features (some, accidently..). This was caused mostly by the fact that a page load would also fetch the last x tweets from the 3-6 profiles which had not been updated the longest.. With this new site I can fortunately use cron to fetch tweets, so that helps. I'll also be denormalizing the db a little so it needs less joins, optimize it for faster selects instead of size. Now, main question: how do I figure out which profiles to check for new tweets in an efficient manner? Some people will be tweeting more often than others, some will tweet in bursts (this happens a lot). I want to keep the front page of the site as "current" as possible. If it comes to, say, 300 profiles, and I check 5 every minute, some tweets will only appear an hour after the fact. I can check more often (up to 20K) but want to optimize this as much as possible, both to not hit the rate limit and to not run out of resources on the local server (it hit mysql's connection limit with that other site). Question 2: since cron only "runs" once a minute, I figure I have to check multiple profiles each minute - as stated, at least 5, possibly more. To try and spread it out over that minute I could have it sleep a few seconds between batches or even single profiles. But then if it takes longer than 60 seconds altogether, the script will run into itself. Is this a problem? If so, how can I avoid that? Question 3: any other tips? Readmes? URLs?

  • Is it possible to make the iPhone keyboard invisible / remove it without resigning first responder?

    - by Alex Gosselin
    I am looking for a way to show my own input view (a UITableView) to enter certain keywords in a UITextView faster than typing them, and also be able to type into this text view the normal way. My solution has a button that causes the keyboard to disappear, revealing the table view underneath it. Problem is I can't figure out how to make the keyboard go away without resigning first responder, and losing the cursor. Has anyone accomplished this before? Thanks for any help.

  • instantiate object with reflection using constructor arguments

    - by justin
    I'm trying to figure out how to instantiate a case class object with reflection. Is there any support for this? The closest I've come is looking at scala.reflect.Invocation, but this seems more for executing methods that are a part of an object. case class MyClass(id:Long, name:String) def instantiate[T](className:String)(args:Any*) : T = { //your code here } Is close to the API I'm looking for. Any help would be appreciated.

  • A better name for INeedSomething... ?

    - by Daniel Severin
    I was trying pick a name for an interface through which I can pass something into an object like: If the object is INeedX then SetX(some x) method will be called; If the object is INeedY then SetY(some y) method will be called; and so on. (funny as hell, I know :) ) I try to find a different name for this kind of interfaces but I can't figure this out. Does anybody have an idea how to name the INeedSomething interface ?

  • IE not showing jquery append() images

    - by Johannes Ruuska
    Ok, so i took John Raasch's slideshow script and modyfied it too dynamicly fetch images from folders on the server through ajax. The slideshow work like a charm in FF and Chrome but IE is not showing the images. And since IE's javascript debugging possibilities is close to none I cant figure out what is crashing. Javascript (indenting got messed up when pasting here but you get the code anyway): function slideSwitch() { var $active = $('#box_bildspel IMG.active'); if ( $active.length == 0 ) $active = $('#box_bildspel IMG:last'); var $next = $active.next().length ? $active.next() : $('#box_bildspel IMG:first'); $active.addClass('last-active'); $next.css({opacity: 0.0}) .addClass('active') .animate({opacity: 1.0}, 1000, function() { $active.removeClass('active last-active'); }); } $(document).ready(function(){ $.get('includes/bildspel.php?page='+page, function(r){ var file = r.split('!'); var path = 'pic/bildspel/'+page+'/'; var data = ''; if(file != null && file != ''){ $.each(file, function(key, value){ if(key == 0) { $('#box_bildspel').append('<img src="'+path+value+'" class="active"></img>'); //console.log(path+value); } else { $('#box_bildspel').append('<img src="'+path+value+'"></img>'); //console.log(path+value); } }); } if(file.length > 1){ $(function() { setInterval( "slideSwitch()", 4000 ); }); } }); }); PHP: <?php function getimgs($page) { $path = '../pic/bildspel/'.$page; $files = ''; if ($handle = opendir($path)) { while (false !== ($file = readdir($handle))) { if ($file !== '.' && $file !== '..') { $files .= $file.'!'; } } closedir($handle); echo substr_replace($files ,"",-1);; } } getimgs($_GET['page']); ?> Tested in IE 7 & 8 Any ideas? I have a deadline on this site for tomorrow (april 23) would appreciate VERY much if someone could figure this on out for me, thanks in advance!
