• What does the `dmesg` error: "composite sync not supported" mean?

  - by M. Tibbits

  Question: I see [ 20.473125] composite sync not supported and several such entries when I run dmesg. What do they mean? Background: I'm trying to debug a problem where my laptop won't suspend. Since acpi seems happy and I can suspend easily from the command line, I've turned to tracking down all boot-up errors/warnings. So I run dmesg | grep not and, amongst other shtuff, I get: 728:[ 17.267120] composite sync not supported 733:[ 18.009061] composite sync not supported 740:[ 18.159289] registered panic notifier 749:[ 18.162500] vga16fb: not registering due to another framebuffer present 757:[ 18.598251] composite sync not supported 776:[ 20.473125] composite sync not supported 777:[ 20.932266] composite sync not supported 778:[ 28.350231] composite sync not supported 779:[ 28.924913] composite sync not supported 780:[ 35.480658] composite sync not supported And the full log for the few lines right around that first appearance (line 728) is listed at the bottom of my post (I'd happily include anything else). Any ideas what could be causing this? I've read several sites: Ubuntuforums #1 IRC Chat #1 One post talks about ??Adobe flash?? causing this error? Some others also suggest that it might be an nvidia related problem, but I've got a Dell Latitude D630 with an integrated Intel graphics -- so nvidia isn't the problem.

• Looking into the JQuery Image Zoom Plugin

  - by nikolaosk

  I have been using JQuery for a couple of years now and it has helped me to solve many problems on the client side of web development.  You can find all my posts about JQuery in this link. In this post I will be providing you with a hands-on example on the JQuery Image Zoom Plugin.If you want you can have a look at this post, where I describe the JQuery Cycle Plugin.You can find another post of mine talking about the JQuery Carousel Lite Plugin here.I will be writing more posts regarding the most commonly used JQuery Plugins. I have been using extensively this plugin in my websites.You can use this plugin to move mouse around an image and see a zoomed in version of a portion of it. In this hands-on example I will be using Expression Web 4.0.This application is not a free application. You can use any HTML editor you like. You can use Visual Studio 2012 Express edition. You can download it here.  You can download this plugin from this link I launch Expression Web 4.0 and then I type the following HTML markup (I am using HTML 5) <html lang="en">  <head>    <title>Liverpool Legends</title>        <meta http-equiv="Content-Type" content="text/html;charset=utf-8" >        <link rel="stylesheet" type="text/css" href="style.css">        <script type="text/javascript" src="jquery-1.8.3.min.js"> </script>     <script type="text/javascript" src="jqzoom.pack.1.0.1.js"></script>        <script type="text/javascript">        $(function () {            $(".nicezoom").jqzoom();        });    </script>       </head>  <body>    <header>        <h1>Liverpool Legends</h1>    </header>        <div id="main">            <a href="championsofeurope-large.jpg" class="nicezoom" title="Champions">        <img src="championsofeurope.jpg"  title="Champions">    </a>          </div>            <footer>        <p>All Rights Reserved</p>      </footer>     </body>  </html>   This is a very simple markup. I have added one large and one small image (make sure you use your own when trying this example) I have added references to the JQuery library (current version is 1.8.3) and the JQuery Image Zoom Plugin. Then I add 2 images in the main div element.Note the class nicezoom inside the href element. The Javascript code that makes it all happen follows.    <script type="text/javascript">        $(function () {            $(".nicezoom").jqzoom();        });    </script>     It couldn't be any simpler than that. I view my simple in Internet Explorer 10 and it works as expected. I have tested this simple solution in all major browsers and it works fine.Inside the head section we can add another Javascript script utilising some more options regarding the zoom plugin.   <script type="text/javascript">            $(function () {        var options = {                  zoomType: 'standard',                  lens:true,                  preloadImages: true,                  alwaysOn:false,                  zoomWidth: 400,                  zoomHeight: 350,                  xOffset:190,                  yOffset:80,                  position:'right'                          };          $('.nicezoom').jqzoom(options);      });         </script> I would like to explain briefly what some of those options mean. zoomType - Other admitted option values are 'reverse','drag','innerzoom' zoomWidth - The popup window width showing the zoomed area zoomHeight - The popup window height showing the zoomed area xOffset - The popup window x offset from the small image.  yOffset - The popup window y offset from the small image.  position - The popup window position.Admitted values:'right' ,'left' ,'top' ,'bottom' preloadImages - if set to true,jqzoom will preload large images. You can test it yourself and see the results in your favorite browser. Hope it helps!!!

• Aptronyms: fitting the profession to the name

  - by Tony Davis

  Writing a recent piece on the pains of index fragmentation, I found myself wondering why, in SQL Server, you can’t set the equivalent of a fill factor, on a heap table. I scratched my head…who might know? Phil Factor, of course! I approached him with a due sense of optimism only to find that not only did he not know, he also didn’t seem to care much either. I skulked off thinking how this may be the final nail in the coffin of nominative determinism. I’ve always wondered if there was anything in it, though. If your surname is Plumb or Leeks, is there even a tiny, extra percentage chance that you’ll end up fitting bathrooms? Some examples are quite common. I’m sure we’ve all met teachers called English or French, or lawyers called Judge or Laws. I’ve also known a Doctor called Coffin, a Urologist called Waterfall, and a Dentist called Dentith. Two personal favorites are Wolfgang Wolf who ended up managing the German Soccer team, Wolfsburg, and Edmund Akenhead, a Crossword Editor for The Times newspaper. Having forgiven Phil his earlier offhandedness, I asked him for if he knew of any notable examples. He had met the famous Dr. Batty and Dr. Nutter, both Psychiatrists, knew undertakers called Death and Stiff, had read a book by Frederick Page-Turner, and suppressed a giggle at the idea of a feminist called Gurley-Brown. He even managed to better my Urologist example, citing the article on incontinence in the British Journal of Urology (vol.49, pp.173-176, 1977) by A. J. Splatt and D. Weedon. What, however, if you were keen to gently nudge your child down the path to a career in IT? What name would you choose? Subtlety probably doesn’t really work, although in a recent interview, Rodney Landrum did congratulate PowerShell MVP Max Trinidad on being named after a SQL function. Grant “The Memory” Fritchey (OK, I made up that nickname) doesn’t do badly either. Some surnames, seem to offer a natural head start, although I know of no members of the Page-Reid clan in the profession. There are certainly families with the Table surname, although sadly, Little Bobby Tables was merely a legend by xkcd. A member of the well-known Key family would need to name their son Primary, or maybe live abroad, to make their mark. Nominate your examples of people seemingly destined, by name, for their chosen profession (extra points for IT). The best three will receive a prize. Cheers, Tony.

• Business Strategy - Google Case Study

  Business strategy defined by SMBTN.com is a term used in business planning that implies a careful selection and application of resources to obtain a competitive advantage in anticipation of future events or trends. In more general terms business strategy is positioning a company so that it has the greatest competitive advantage over others in the markets and industries that they participate in. This process involves making corporate decisions regarding which markets to provide goods and services, pricing, acceptable quality levels, and how to interact with others in the marketplace. The primary objective of business strategy is to create and increase value for all of its shareholders and stakeholders through the creation of customer value. According to InformationWeek.com, Google has a distinctive technology advantage over its competitors like Microsoft, eBay, Amazon, Yahoo. Google utilizes custom high-performance systems which are cost efficient because they can scale to extreme workloads. This hardware allows for a huge cost advantage over its competitors. In addition, InformationWeek.com interviewed Stephen Arnold who stated that Google’s programmers are 50%-100% more productive compared to programmers working for their competitors.  He based this theory on Google’s competitors having to spend up to four times as much just to keep up. In addition to Google’s technological advantage, they also have developed a decentralized management schema where employees report directly to multiple managers and team project leaders. This allows for the responsibility of the technology department to be shared amongst multiple senior level engineers and removes the need for a singular department head to oversee the activities of the department.  This is a unique approach from the standard management style. Typically a department head like a CIO or CTO would oversee the department’s global initiatives and business functionality.  This would then be passed down and administered through middle management and implemented by programmers, business analyst, network administrators and Database administrators. It goes without saying that an IT professional’s responsibilities would be directed by Google’s technological advantage and management strategy.  Simply because they work within the department, and would have to design, develop, and support the high-performance systems and would have to report multiple managers and project leaders on a regular basis. Since Google was established and driven by new and immerging technology, all other departments would be directly impacted by the technology department.  In fact, they would have to cater to the technology department since it is a huge driving for in the success of Google.

• How To Completely Disable Subtitles in VLC

  - by The Geek

  If you watch a lot of videos using VLC, you might have noticed that it enables subtitles by default if they are there, which can be pretty annoying at times. Here’s the quick tip to disable them entirely. Of course, you can always turn them back on if you want on an individual video basis. Disable Subtitles Head into the VLC preferences, and then click the All button at the bottom of the screen. On the left-hand side, choose Video –> Subtitles/OSD, and then uncheck the boxes for “Autodetect subtitle files”, Enable sub-pictures, and On Screen Display. That should do it, unless the subtitles are forced in the video for some reason. Note: Certain video formats like MKV can sometimes have subtitles enabled even though there isn’t a separate subtitles file. This is why you need to remove “Enable sub-pictures” as well, which totally disables the on-screen text. You can choose to only uncheck the autodetecting of subtitles instead if you’d prefer. And of course, you can simply right-click on the video, head to Video –> Subtitles Track and then choose the subtitles if you still wanted them. Note: this only works if the “enable sub-pictures” option is still enabled. And thus ends the tale of disabling those fracking subtitles. Starbuck approves.

• adapting a Unity gravitational script to allow moons

  I'm using this script: http://wiki.unity3d.com/index.php/Simple_planetary_orbits to get a solar system going in Unity, but it doesn't seem to support creating bodies that orbit other moving bodies (or I am using it incorrectly). Any idea about how to modify it so that it does (or just use it correctly)? I've been beating my head against this problem for a couple hours, and I really don't feel like I have any idea what I'm doing. Thanks in advance.

• App_Offline.htm, taking site down for maintenance

  - by Vipin

  There is much simpler and graceful way to shut down a site while doing upgrade to avoid the problem of people accessing site in the middle of a content update.   Basically, if you place file with name 'app_offline.htm' with below contents in the root of a web application directory, ASP.NET will shut-down the application,  and stop processing any new incoming requests for that application.  ASP.NET will also then respond to all requests for dynamic pages in the application by sending back the content of the app_offline.htm file (for example: you might want to have a “site under construction” or “down for maintenance” message).   Then after upgrade, just rename/delete app_offline.htm file…and the site would be back to normal. Just remember that the size of the file should be greater than 512 bytes, doesn't matter even if you add some comments to it to push the byte size as long as it's of the size greater than 512 - it'll work fine.     <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html http://www.w3.org/1999/xhtml"http://www.w3.org/1999/xhtml" ><head>    <title>Maintenance Mode - Outage Message</title></head><body>    <h1>Maintenance Mode</h1>     <p>We're currently undergoing scheduled maintenance.

• Set Covering : Runtime hang\error at function call in c

  - by EnthuCrazy

  I am implementing a set covering application which uses cover function int cover(set *skill_list,set *player_list,set *covering) Suppose skill_set={a,b,c,d,e}, player_list={s1,s2,s3} then output coverin ={s1,s3} where say s1={a,b,c}, s3={d,e} and s2={b,d}. Now when I am calling this function it's hanging at run (set_cover.exe stopped working). Here is my cover function: typedef struct Spst_{ void *key; set *st; }Spst; int cover(set *skill_list,set *player_list,set *covering) { Liste *member,*max_member; Spst *subset; set *intersection; void **data; int max_size; set_init(covering); //to initialize set covering initially while(skill_list->size>0&&player_list->size>0) { max_size=0; for(member=player_list->head;member!=NULL;member=member->next) { if(set_intersection(intersection,((Spst *)(member->data))->st,skill_list)!=0) return -1; if(intersection->size>max_size) { max_member=member; max_size=intersection->size; } set_destroy(intersection); //at the end of iteration } if(max_size==0) //to check for no covering return -1; subset=(Spst *)max_member->data; //to insert max subset from play list to covering set set_inselem(covering,subset); for(member=(((Spst *)max_member->data)->st->head);member!=NULL;member=member->next) //to rem elem from skill list { data=(void **)member->data; set_remelem(skill_list,data); } set_remelem(player_list,(void **)subset); //to rem subset from set of subsets play list } if(skill_list->size>0) return -1; return 0; } Now assuming I have defined three set type sets(as stated above) and calling from main as cover(skills,subsets,covering);=> runtime hang Here Please give inputs on the missing link in this or the prerequisites for a proper call to this function type required. EDIT: Assume other functions used in cover are tested and working fine.

• How do you overcome your own coding biases when handed legacy code?

  - by Bryan M.

  As programmers, we often take incredible pride in our skills and hold very strong opinions about what is 'good' code and 'bad' code. At any given point in our careers, we've probably had some legacy system dropped in our laps, and thought 'My god, this code sucks!' because it didn't fit into our notion of what good code should be, despite the fact that it may have well been perfectly functional, maintainable code. How do you prepare yourself mentally when trying to get your head around another programmer's work?

• How can I convince IE to honor my explicit instructions to make a table column X pixels wide? [migrated]

  - by AnthonyWJones

  Please consider this small but complete chunk of HTML: <!DOCTYPE html > <html> <head> <title>Test</title> <style type="text/css"> span {overflow:hidden; white-space:nowrap; } td {overflow:hidden; text-overflow:ellipsis} </style> </head> <body> <table cellspacing="0" > <tbody> <tr> <td nowrap="nowrap" style="max-width:30px; width:30px; white-space:nowrap; "><span>column 1</span></td> <td nowrap="nowrap" style="max-width:30px; width:30px; white-space:nowrap; "><span>column 2</span></td> <td nowrap="nowrap" style="max-width:30px; width:30px; white-space:nowrap; "><span>column 3</span></td> </tr> </tbody> </table> </body> </html> If you render the above in Chrome you'll see the effect I'm looking for. However render it in IE8 or 9 the width and/or max-width is ignored. So my question is how do get IE to simply let me specify the width of a cell explicitly? BTW, I've tried various combinations of table-layout:fixed and using colgroup with cols and all sorts, nothing I've tried convinces IE to what I'm clearly asking it to explicitly do? If I had any hair before starting this I wouldn't have any left by now.

• getting bone base and tip positions from a transform matrix?

  - by ddos

  I need this for a Blender3d script, but you don't really need to know Blender to answer this. I need to get bone head and tip positions from a transform matrix read from a file. The position of base is the location part of the matrix, length of the bone (distance from base to tip) is the scale, position of the tip is calculated from the scale (distance from bone base) and rotation part of the matrix. So how to calculate these? bone.base([x,y,z]) # x,y,z - floats bone.tip([x,y,z])
