Tar an gzip together, but the other way round?

- by Boldewyn

Gzipping a tar file as whole is drop dead easy and even implemented as option inside tar. So far, so good. However, from an archiver's point of view, it would be better to tar the gzipped single files. (The rationale behind it is, that data loss is minified, if there is a single corrupt gzipped file, than if your whole tarball is corrupted due to gzip or copy errors.) Has anyone experience with this? Are there drawbacks? Are there more solid/tested solutions for this than find folder -exec gzip '{}' \; tar cf folder.tar folder

Starting VNC server using vncserver :1, client can connect to the server but it shows only a black screen with a X cursor.

Can I rent exclusive time on a powerful server running linux? [closed]

- by Mark Borgerding

My company is involved in a proposal that requires speed estimates of our software on a server with the latest & greatest processors. This is not the first time we've been in this situation. The servers themselves are too expensive to buy a new one every time, so we end up extrapolating from what we have. There are so many variables: processor generation & speed, memory speed, memory channels, cache configurations; it makes extrapolation difficult and error-prone. Is there a business that rents time on the newest servers? At least part of the time we'd need exclusive access to an otherwise quiescent system either via ssh shell access or unattended batch jobs. I am not looking for general cloud computing services. I don't need much time on the server, but it needs to be exclusive. And the server needs to be pretty cutting edge for a solid basis of estimate.

Would SSD drives benefit from a non-default allocation unit size?

- by davebug

The default allocation unit size recommended when formatting a drive in our current set-up is 4096 bytes. I understand the basics of the pros and cons of larger and smaller sizes (performance boost vs. space preservation) but it seems the benefits of a solid state drive (seek times massively lower than hard disks) may create a situation where a much smaller allocation size is not detrimental. Were this the case it would at least partially help to overcome the disadvantage of SSD (massively higher prices per GB). Is there a way to determine the 'cost' of smaller allocation sizes specifically related to seek times? Or are there any studies or articles recommending a change from the default based on this newer tech? (Assume the most average scattering of sizes program files, OS files, data, mp3s, text files, etc.)

OS Isolation: Virtualization or Dual-Boot Duplication, a General How To?

- by Mr_CryptoPrime

I want to isolate my windows 7 operating system and I have looked into virtualization. This should work with Linux, however, I do want to still have a way to run windows 7 securely, but without significant performance loss, thus eliminating virtualization for that. I know that you can dual boot because I currently do so with my XP/Linux system. Is there a way that I can duplicate my windows 7 system so I can select one at bootup? This way I can ensure that each OS is isolated and not worry about performance loss. However, I am having a lot of trouble finding a solid method for OS duplication?! Is this even possible or must I buy two versions of win7 and somehow install them separately? Any information regarding this would be helpful, thanks! Essentially I want, Two instances of win7 (not necessarily simultaneously running) Each are isolated from one another so that a security breach in one doesn't affect the other. There is no performance loss in either from doing so

What steps are required to get DB2 working again after renaming the Windows XP system it was running on?

- by Suppressingfire

I think this is a fairly well known problem, but I haven't found a really solid solution to add to my toolbox. Here's the sequence of steps that leads to the problem: Install Windows (e.g., XP), naming the system XXX Install DB2 and create some databases Rename the system from XXX to YYY (via the System control panel's Computer Name tab Reboot and find DB2 unable to start How can I get DB2 up and running again without having to reinstall it and without having to rename the system back to XXX? I did find a blog post that hints at some registry values to tweak, but I'm hoping the SF community can come up with a solution in which I can have more confidence.

How to exchange the HDD of a MacBook Pro?

- by Another Registered User

I've bought an Solid State Drive (SSD) for my MacBook Pro, and now I need to exchange it somehow. Would this strategy work? 1) Create an backup with Time Machine (Snow Leopard) 2) Then replace the old HDD 3) Insert the new HDD 4) Install Snow Leopard (same version as previously used) 5) Open up Time Machine, and recover from the last backup I'm not sure about how to do the last part. Is that hard? What are the neccessary steps? Or is there a better way? Maybe I don't need to re-install Snow Leopard completely? Maybe the Install CD already offers an option to recover from Backup?

Cross Browser Issue

- by dazedandconfused

My background is in WinForms programming and I'm trying to branch out a bit. I'm finding cross-browser issues a frustrating barrier in general, but have a specific one that I just can't seem to work through. I want to display an image and place a semi-transparent bar across the top and bottom. This isn't my ultimate goal, of course, but it demonstrates the problem I'm having ina a relatively short code fragment so let's go with it. The sample code below displays as intended in Chrome, Safari, and Firefox. In IE8, the bar at the bottom doesn't appear at all. I've researched it for hours but just can't seem to come up with the solution. I'm sure this is some dumb rookie mistake, but gotta start somewhere. Code snippet... <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title></title> <script type="text/javascript" language="javascript"> </script> <style type="text/css"> .workarea { position: relative; border: 1px solid black; background-color: #ccc; overflow: hidden; cursor: move; -moz-user-focus: normal; -moz-user-select: none; unselectable: on; } .semitransparent { filter: alpha(opacity=70); -moz-opacity: 0.7; -khtml-opacity: 0.7; opacity: 0.7; background-color: Gray; } </style> </head> <body style="width: 800px; height: 600px;"> <div id="workArea" class="workarea" style="width: 800px; height: 350px; left: 100px; top: 50px; background-color: White; border: 1px solid black;"> <img alt="" src="images/TestImage.jpg" style="left: 0px; top: 0px; border: none; z-index: 1;" /> <div id="topBar" class="semitransparent" style="position: absolute;width: 800px; height: 75px; left: 0px; top: 0px; min-height: 75px; border: none; z-index: 2;" /> <div id="bottomBar" class="semitransparent" style="position: absolute; width: 800px; height: 75px; left: 0px; top: 275px; min-height: 75px; border: none; z-index: 2;" /> </div> </body> </html>

Which part of this simple script is breaking internet explorer?

I'm writing a simple virtual keyboard for Arabic (indic) digits. Just links that, when clicked, produce the corresponding Unicode Indic character.

ie9/CSS: Flyout menu not working in ie9, but looks great in Firefox/Chrome

Please see this flyout menu: http://www.caseen.com/store.html. It looks amazing in both Firefox and Chrome, but not in IE9! Trying to see what is going on =(. It looks like ie9 is completing ignoring the stylesheet, but in error checking and clicking ie9 direct mode, it shows up however VERY ugly with huge nasty white borders around the links! Please see my code: <div class="flyout"> <ul>   <li><a href="view_category.asp?cat=CATID"> CATEGORY</a>  <ul> <li><a href="view_category.asp?cat=CATID"> CATEGORY</a></li> </ul>  </li> </ul> </div> AND CSS .flyout { width: 130px; height: auto; position:relative; margin: -10 0; padding: 0; z-index:10000; } .flyout ul li a { display:block; text-decoration:none; color: #fff; width: 130px; border: solid; border-color: #000; border-width: 0 0 0 5px; text-align:left; font-size:12px; line-height: 25px; } .flyout ul { padding:0px; list-style-type: none; } .flyout ul li { float:left; margin-right:1px; position:relative; } .flyout ul li ul { display: none; } .flyout ul li:hover a { border: solid; border-color: #fff; border-width: 0 2 0 5px; color: #60dfe5; } .flyout ul li:hover ul { display:block; position:absolute; top:0; left:130px; width:10px; } .flyout ul li:hover ul li a.hide { background:#000; color:#fff; } .flyout ul li:hover ul li:hover a.hide {width:180px;} .flyout ul li:hover ul li ul {display: none;} .flyout ul li:hover ul li a { display:block; background:#000; color:#60dfe5; width:200px; } .flyout ul li:hover ul li a:hover { background:#000; color:#fff; } Thanks, Brandon

jQuery: Div elements are not showing up

I am adapting the Coverflow technique to work with a div. Following is the html: <html> <head> <meta http-equiv="Content-type" content="text/html; charset=utf-8" /> <style type="text/css" media="screen"> body,html { margin: 0; padding: 0; background: #000; height: 100%; color: #eee; font-family: Arial; font-size: 10px; } div.magnifyme { height: 80px; padding: 80px; position: absolute; top: 0px; left: 0px; width: 8000px; } div.wrapper { margin: 0px; height: 470px; /*border: 2px solid #999;*/ overflow: hidden; padding-left: 40px; right: 1px; width: 824px; position: relative; } div.container {position: relative; width: 854px; height: 480px; background: #000; margin: auto;} div.nav {position: absolute; top: 10px; width: 20%; height: 10%; right: 1px; } div.magnifyme div { position: absolute; width: 300px; height: 280px; float: left; margin: 5px; position: relative; border: 2px solid #999; background: #500; } </style> <script type="text/javascript" src="jquery-1.3.2.js"></script> <script type="text/javascript" src="ui.coverflow.js"></script> <script type="text/javascript"> $(function() { $("div.magnifyme").coverflow(); $("#add").click(function() { location.reload(); $(".magnifyme").append("<div id=\"div5\">hello world</div>"); $("div.magnifyme").coverflow(); }); }); </script> </head> <body> <div class="container"> <div class="wrapper"> <div class="magnifyme"> <div id="div0">This is div 0</div> <div id="div1">This is div 1</div> <div id="div2">This is div 2</div> <div id="div3">This is div 3</div> <div id="div4">This is div 4</div> </div> </div> <div class="nav"> <button type="button" id="add">Add to Deck</button> </div> </div> </body> </html> The coverflow function (included as a js file in the head section) is here. When I click the button, I was expecting it to add a DIV to the already present deck. For some reason, it doesn't show the newly added DIV. I tried calling the coverflow() function after I added the new element but that didn't work either. Is there any way I can make this work?

Div in HTML not floating left with CSS

Edit of self referencing HABTM in cakephp works, sometimes

- by Odegard

I'm using a self referencing HABTM model with Participants. You sign up for an event and when you log in to your reservation/profile you see a list of other participants and you can choose to add yourself and others into various groups; share hotel room, share transportation from airport etc. What I've managed so far: 1) In my profile I see the list of all other participants with checkboxes. Great so far. 2) Adding another participant works fine. Next time I edit, the participant I added is shown as checked. 3) Removing another participant works fine too as long as you still have checked participants before you submit! Again, with words: There are 3 participants. I'm logged in as one of them, and I see the 2 other people on the participants list. I choose to check both of them. This works fine (always). Later I choose to remove one of them (by unchecking the checkbox and hitting submit). This also works fine (always). If I want to remove the last checkbox... nothing is updated (always!). What's curious is that I can add and remove any odd combination of participants and it will always work UNLESS I choose to remove every participants in one go (removing a one and only participant is a special case of "remove all checked participants"). As far as I know, HABTMs work by first deleting all relations, then re-saving them. I can see that in my tables when I remove, add, remove, add the same participant over and over again - the id on the HABTM table is always increasing. When I deselect all participants at once, however, the relations are not updated. The ids stay the same, so it's like the save never happened. This behaviour is so specific and peculiar, I have a feeling I'm missing something obvious here. Anyway, here's the relevant code: Model class Participant extends AppModel { var $hasAndBelongsToMany = array( 'buddy' = array( 'className' = 'Participant', 'joinTable' = 'participants_participants', 'foreignKey' = 'participant_id', 'associationForeignKey' = 'buddy_id', 'unique' = true, ) ); Controller function edit($id = null) { if (!$id && empty($this-data)) { $this-Session-setFlash(__('Invalid Participant', true)); $this-redirect(array('action'='index')); } if (!empty($this-data)) { if ($this-Participant-saveAll($this-data)) { $this-Session-setFlash(__('The Participant has been saved', true)); $this-redirect(array('action'='index')); } else { $this-Session-setFlash(__('The Participant could not be saved. Please, try again.', true)); } } if (empty($this-data)) { $this-data = $this-Participant-read(null, $id); } // Fetching all participants except yourself $allParticipants = $this-Participant-find('list', array('conditions' = array('participant.id ' = $id))); // Fetching every participant that has added you to their list $allBuddies = $this-Participant-ParticipantsParticipant-find('list', array( 'conditions' = array('buddy_id' = $id), 'fields' = 'ParticipantsParticipant.participant_id', 'order' = 'ParticipantsParticipant.participant_id ASC' )); $this-set(compact('allParticipants','allBuddies')); } View echo $form-create('Participant'); echo $associations-habtmCheckBoxes($allParticipants, $this-data['buddy'], 'buddy', 'div', '\'border: 1px solid #000;\'', '\'border: 1px solid #000;\''); echo $form-end('Submit'); I'm using a slightly modified helper, habtmCheckBoxes, found here: http://cakeforge.org/snippet/detail.php?type=snippet&id=190 It works like this: function habtmCheckBoxes($rows=array(), $selectedArr=array(), $modelName, $wrapTag='p', $checkedDiv, $uncheckedDiv) {}

CSS: Horizontal UL: Getting it centered

- by Steve

I'm trying to make a horizontal menu/list. It has a mix of independent buttons and buttons that are wrapped in their own individual forms. With much hacking I got all of the buttons, in forms and not in forms to align horizontally. I haven't been able to get the whole thing to center on the page though. Could someone point out to me what I am not seeing? <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"><head> <meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"> <link rel="shortcut icon" href="http://localhost:7001/nsd/images/favicon.ico"> <link rel="StyleSheet" href="veci_files/nsd.css" type="text/css"> <style type = "text/css"> #horizontal_li_menu_container ul { margin-left: auto; margin-right:auto; text-align:center; border: 1px solid green; width:1000px; } #horizontal_li_menu_container_ul { list-style-type: none; text-decoration: none; border: 1px solid red; } #horizontal_li_menu_container li { display: inline;float:left; } </style> </head> <body> <div id = "horizontal_li_menu_container"> <ul id = "horizontal_li_menu_container_ul"> <li> <input value="Update" onclick="location.href='#'" name="button" type="button"/> </li> <li> <form name="formExportVECI" method="post" action="exportveci"> <input name="person_id" value="661774" type="hidden"> <input name="submitExport" value="Export To Microsoft Excel" type="submit"> </form> </li> <li> <form id="ufdh" name="formImportVECI" action="importveci" method="post" enctype="multipart/form-data"> <input name="person_id" value="661774" type="hidden"> <input value="Import From Microsoft Excel" path="Upload" type="submit"> <input id="fileData" name="fileData" value="" type="file"> </form> </li> <li> <input value="Search/Home" onclick="location.href='search'" name="buttonHome" type="button"/> </li> </ul> </div> </body></html>

I have switched out the precent with em units, and still no workie. Any help would be greatly appreciated. My end goal is to have the contentplaceholder always be in the center of page regardless of the resolution of the monitor <div style="width:20%"/> <div style="width:60"> contentplaceholercode </div> <div style="width:20%"/> <table> <tr > <td style="width:20%"> </td> <td style="width:60> </td> <td style="width:20%"> </td> </tr> </table> code for master and code for content page <%@ Master Language="C#" AutoEventWireup="true" CodeBehind="Master.master.cs" Inherits="WorkRecordr.Master" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <script src="Assets/Scripts/Jqeury1.4.4.js" type="text/javascript"></script> <title></title> <style type="text/css"> body { background-color: #326598; } .outer { width: 100%; border: solid 1px gray; padding: 1px; } .inner { border: solid 1px gray; width: 70%; margin-left: auto; margin-right: auto; } </style> </head> <body> <div style="text-align: center"> <asp:ContentPlaceHolder ID="head" runat="server"> </asp:ContentPlaceHolder> </div> <form id="form1" runat="server"> <div class="outer"> <div class="inner"> <asp:ContentPlaceHolder ID="ContentPlaceHolder1" runat="server"> </asp:ContentPlaceHolder> </div> </div> </form> </body> </html> <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="test.aspx.cs" Inherits="WorkRecordr.test" MasterPageFile="~/Master.Master" %> <asp:Content ContentPlaceHolderID="ContentPlaceHolder1" runat="server"> aaaaaaaaa***aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa***aaaaaaaaaaaaaaaa </asp:Content>

Accordion "growing out" from its container - in IE7/8

- by Richard Knop

I think this problem is best explained by images. This is how my accordion looks: When you click on the small plus/minus icons the slides under each chapter will expand/collapse. However when the content in the accordion grows too tall, it grows out from its container. So if I click on more plus icons the accordion will look like this (not pretty): As you can see, the container is not growing taller together with the accordion and it does not look good. This problem only occurs in IE7 and IE8. It works in Firefox and Chrome. The HTML looks like this (simplified): <div id="content"> <div class="box2 rounded-corners"> <div class="chapters"> <h3><a href="/clientarea/view/archived-course/teid/133">Obsah</a></h3> <div id="accordion"> <ul> ... // accordion content - too long ... // accordion content - too long </ul> <div class="clear"> </div> </div> <div class="clear"> </div> </div> <div class="training-body"> ... // content to the right of the accordion </div> </div> </div> The CSS, again siplified: html, body { height: 100%; width: 100%; overflow: auto; } #content { background: white url('/images/background_middle.png') left top repeat-x; padding: 13px; min-height: 40em; height: auto !important; height: 40em; } /* this is the div with rounded corners */ #content .box2 { background: white; padding: 0 15px 15px; border: 1px solid #C5E3F8; position: relative; } /* left sidebar 98 #content div.chapters { float: left; width: 224px; } /* orange heading "OBSAH" */ #content div.chapters h3 { color: #ff6e19; text-transform: uppercase; font-size: .9em; text-align: center; padding-bottom: .5em; margin-top: 1em; margin-bottom: 0; } #content div.chapters h3 a { color: #ff6e19; } /* accordion */ #accordion { width: 226px; border-top: 1px solid #c5e3f8; } #accordion ul { padding-left: 0; margin-top: 0; margin-bottom: 0; margin-left: 0; } /* area to the right of the accordion */ #content div.training-body { float: left; padding-left: 0px; width: 748px; line-height: 1.3em; }

Select dropdown with fixed width cutting off content in IE

- by aaandre

The issue: Some of the items in the select require more than the specified width of 145px in order to display fully. Firefox behavior: clicking on the select reveals the dropdown elements list adjusted to the width of the longest element. IE6 & IE7 behavior: clicking on the select reveals the dropdown elements list restricted to 145px width making it impossible to read the longer elements. The current UI requires us to fit this dropdown in 145px and have it host items with longer descriptions. Any advise on resolving the issue with IE? The top element should remain 145px wide even when the list is expanded. Thank you! The css: select.center_pull { background:#eeeeee none repeat scroll 0 0; border:1px solid #7E7E7E; color:#333333; font-size:12px; margin-bottom:4px; margin-right:4px; margin-top:4px; width:145px; } Here's the select input code (there's no definition for the backend_dropbox style at this time) <select id="select_1" class="center_pull backend_dropbox" name="select_1"> <option value="-1" selected="selected">Browse options</option> <option value="-1">------------------------------------</option> <option value="224">Option 1</option> <option value="234">Longer title for option 2</option> <option value="242">Very long and extensively descriptive title for option 3</option> </select> Full html page in case you want to quickly test in a browser: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>dropdown test</title> <style type="text/css">  </style> </head> <body> <p>Select width test</p> <form id="form1" name="form1" method="post" action=""> <select id="select_1" class="center_pull backend_dropbox" name="select_1"> <option value="-1" selected="selected">Browse options</option> <option value="-1">------------------------------------</option> <option value="224">Option 1</option> <option value="234">Longer title for option 2</option> <option value="242">Very long and extensively descriptive title for option 3</option> </select> </form> </body> </html>
