• Remote Desktop (Vino-Server) connects but display doesn't work?

  - by kmassada

  Ubuntu comes default with vino-server, I can remote into my machine, and connect to it, however, the display inside my remote client, is a mirror of my own desktop. I tried using one monitor, thinking that's what is the issue but still won't work.

• What will be the impact on SEO if we remove our SSL certificate (url become http instead of https)?

  - by pixeline

  For some weird reason, our domain's content is returned for any https request set to any of our server's hosted domain names. https://domain.com leads to our website, with a proper SSL certificate (so, no warning). https://domain2.com, also hosted on our server but without SSL certificate, leads to a warning, and if accepted, to our website's content! The problem is that any search for our keywords in Google shows "fake websites" on top of ours, with the warning et al. It seems unsolvable so we are thinking about switching back ton nonsecure http . I'm just afraid of losing whatever indexing we have. How can i avoid that? Thanks, a.

• Does a "nofollow" attribute on a link prevent URL discovery by search engines?

  - by Stephen Ostermiller

  I know that nofollow prevents link juice from being passed across a link. But if search engine robots discover a link with a nofollow on it, will they add that link to their crawl queue? In other words, if I create a link to a brand new page and put a rel=nofollow attribute on that link, will it prevent search engine bots (particularly Googlebot) from crawling the page. (Assuming that this link remains the only link into that page.) I've read conflicting reports about this over the years and I'm looking for authoritative references about the current state of affairs. Official statements from Google or published results of independent testing would be ideal.

• Why is <my site url> not indexed by search engines? [closed]

  - by Henrik Erlandsson

  was indexed fine until about a year ago. The only thing I can think of is that search engines throw up at using h5 before h4, or that some person (fantasizing now) has reported my site as unsafe to every search engine. However, I'm not here to speculate. The site validates, and has an RSS feed on the front page, for Pat Morita's sake! To me, it looks like the kind of site search engines would feast on. It's got more than a dozen blogs on it, if nothing else. Hah. :) I was thinking you could identify basically what has changed in search engines (currently, google, yahoo, bing which used to work fine) the last year to make them not find news and blog articles on this site. The site was submitted to Google, oh, way back in 2006. With online crawler tests I get mixed results, some crawlers index fine, some go blank. I don't really know which ones are reliable and am looking to you guys for advice on that. Yes, I am prepared to again verify my site with Google and upload a sitemap, but that's not the topic here. I really would first like to know what change on the site last year could make search engines not index it. (Yees, the robots.txt is fine. Should be nothing to discourage bots there.) It's a very intriguing problem. One which I have yet to find the reason for but would like to know the reason for. Any and all input appreciated, but I would heavily enjoy pertinent advice the most. ;) Edit: Some google searches that don't show up include - aca630 All of which are posted in the news and blogs that are on the front page there. Now, these search terms are extremely specific as the term in is almost unique on the web and ACA630 is also a very qualified search term that can't be confused with mainstream search terms.

• How can I change a video container without re-encoding or compressing the file?

  - by GiH

  When I ripped my Kill Bill DVD I used handbrake and put it into a single avi. I realize that I didn't get the subtitles, so what I want to do is convert the AVI to MKV and put the subtitles in the mkv. How do I go about doing this without losing any qualityI don't care about compressing or anything ju? I don't care about compressing or anything, just want to change the container. If handbrake can do it, I'd prefer to use that since I already have it.

• Does using structure data semantic LocalBusiness schema markup work for local EMD URL's?

  - by ElHaix

  Based on what I have read about Google's recent Panda and Penguin updates, I'm getting the impression that using semantic markup may help improve SEO results. On a EMD (exact match domain) site, that may have been hit, we list location-based products. We are now going to be adding a itemtype="http://schema.org/Product" to each product, with relevant details. However, that product may be available in Los Angeles and also in appear in a Seattle results page. We could add a LocalBusiness item type on each geo page to define the geo location for that page. While the definition states: A particular physical business or branch of an organization. Examples of LocalBusiness include a restaurant, a particular branch of a restaurant chain, a branch of a bank, a medical practice, a club, a bowling alley, etc. We could add use the location property which would simply include the city/state details. I realize that this looks like it is meant for a physical location, however could this be done without seeming black-hat?

• Request format is unrecognized for URL unexpectedly ending exception in web service.

  - by Jalpesh P. Vadgama

  Recently I was getting error when I am calling web service using Java script. I searching on net and debugging I have found following things. Any web service support three kinds of protocol HttpGet,HttpPost and SOAP. In framework 1.0 it was enabled by default but after 1.0 framework it will not be enabled by default due to security issues and WS-Specifications. So we have to enabled them via putting configuration settings in web.config. Here is the code for that. <configuration> <system.web> <webservices> <protocols> <add name="HttpGet"></add> <add name="HttpPost"></add> </protocols> </webservices> </system.web> </configuration> Hope this will help you. Stay tuned for more. Till that Happy programming!!!. Technorati Tags: WebService,Request,Javascript,Ajax

• Google still has record of my old site URL - what to do?

  - by Mayeenul Islam

  I had a blog site, i.e. http://example2.com, then I bought a new domain, i.e. http://example.com and 301 permanent redirected example2.com to example.com. But when I get into the Google Webmaster Tools, if I get some 404, and then click into the link and see the "Linked from" tab, it shows some links like: http://example.com/post-1 http://example2.com/feed http://example2.com/post-1 According to Google, if you change your domain, just use a redirection for at least 4-6 months, but it almost passed. Then why Google has still traces of my old site? The issue is important, because I don't want to pay for the old domain anymore. I tried deleting my existing sitemap.xml and recreating it from the new site, but still such links are stored. What could I do?

• How can I make a webmail URL available from any hosted domain?

  - by James

  I run Roundcube webmail on my VPS. At the moment, it is only accessible from one virtual server hosted on the server, unless a separate Roundcube installation is created for other virtual servers. I would like to be able to make webmail available from any domain/ virtual server that I host, just by adding /webmail to the end. I'm sure Apache must allow me to do this - only problem is, I don't know how! Any ideas?

• If my URL's are static, but then parsed by Javascript, does that make it crawlable?

  - by Talasan Nicholson

  Lets say I have a link: <a href="/about/">About Us</a> But in Javascript [or jQuery] catches it and then adds the hash based off of the href attribute: $('a').click(function(e) { e.preventDefault(); // Extremely oversimplified.. window.location.hash = $(this).attr('href'); }); And then we use a hashchange event to do the general 'magic' of Ajax requests. This allows for the actual href to be seen by crawlers, but gives client-side users with JS enabled an ajax-based website. Does this 'help' the general SEO issues that come along with hashtags? I know hashbangs are 'ok', but afaik they aren't reliable?

• What are all things that do/can happen when a user enters in a web page's URL?

  - by Job

  Sorry if this is a naive title. I am trying to break into web development, which is so far a foreign world to me. I have taken a basic intro to OS, intro to Networking as part of my bachelors degree several years ago. I cannot say that we went into things deeply, beyond academic assignments. I would like to understand things much better regarding to this specific task (e.g what goes on in at the OS level, at networking level, what are other computers involved, where do proxy servers and hackers come in). Again, at the very basic level this has been covered, but I would like to review this specific thing better. Are there chapter(s) os a specific book, or specific SHORT reading that you recommend? I have nothing against your list of 20 favorite books, but I want to understand this one thing better in 2-3 weeks of reading after work / on the weekends (realistically 5-10 hrs per week, so I am looking for about 15-20 hrs of reading material, NO MORE). I am not a fast reader :) Thanks.

• Can't Drag & Drop text to unity launcher (e.g. url's, highlighted text)

  - by patsee

  I'm trying to create a unity launcher icon (.dekstop file) on which you can drop any (selected/highlighted) text from a web browser, google chrome in my case. I know you can use the "MimeType=" key in a .desktop file, but I can't find the right mime type for my scenario. I've tried several text MimeTypes and "text/*", but none of them would work. Does anyone know which MimeType I have to use in order for my launcher icon to accept text when hovering over it?

• What OO Design to use ( is there a Design Pattern )?

  - by Blundell

  I have two objects that represent a 'Bar/Club' ( a place where you drink/socialise). In one scenario I need the bar name, address, distance, slogon In another scenario I need the bar name, address, website url, logo So I've got two objects representing the same thing but with different fields. I like to use immutable objects, so all the fields are set from the constructor. One option is to have two constructors and null the other fields i.e: class Bar { private final String name; private final Distance distance; private final Url url; public Bar(String name, Distance distance){ this.name = name; this.distance = distance; this.url = null; } public Bar(String name, Url url){ this.name = name; this.distance = null; this.url = url; } // getters } I don't like this as you would have to null check when you use the getters In my real example the first scenario has 3 fields and the second scenario has about 10, so it would be a real pain having two constructors, the amount of fields I would have to declare null and then when the object are in use you wouldn't know which Bar you where using and so what fields would be null and what wouldn't. What other options do I have? Two classes called BarPreview and Bar? Some type of inheritance / interface? Something else that is awesome?

• Intermittent 403 errors when using allow to limit access to url with both explicit IP and SetEnvIf

  - by rbieber

  We are running Apache 2.2.22 on a Solaris 10 environment. We have a specific URL that we want to limit access to by IP. We recently implemented a CDN and now have the added complexity that the IP's that a request are shown to be coming from are actually the CDN servers and not the ultimate end user. In the case that we need to back the CDN out, we want to handle the case where either the CDN is forwarding the request, or the ultimate client is sending the request directly. The CDN sends the end user IP address in an HTTP header (for this scenario that header is called "User-IP"). Here is the configuration that we have put in place: SetEnvIf User-IP (\d+\.\d+\.\d+\.\d+) REAL_USER_IP=$1 SetEnvIf REAL_USER_IP "(10\.1\.2\.3|192\.168\..+)" access_allowed=1 <Location /uri/> Order deny,allow Allow from 10.1.2.3 192.168. allow from env=access_allowed Deny from all </Location> This seems to work fine for a time, however at some point the web server starts serving 403 errors to the end user - so for some reason it is restricting access. The odd thing is that a bounce of the web server seems to resolve the issue, but only for a time - then the behavior comes back. It might be worthwhile to note as well that this URL is delegated to a JBoss server via mod_jk. The denial of access is, however; confirmed to be at the Apache layer and the issue only seems to happen after the server has been running for some time.

• Simple XML variable returns "0"

  - by Warren Haskins

  Ok, so im working with tumblr's API and im using SimpleXMLElement with php and ive run into a problem. Basically, when I call on a variable it just prints a zero. for instance : <?php echo $data->posts->post[0]->photo-url[5]; ?> This just breaks the page, and when I leave out the [5] it just prints zero I want to echo the photo-url with the number [5] but I cant get my head around this and its killing me. I just dont understand why it wont work. Heres a sample of the simpleXMLElement print-out : SimpleXMLElement Object ( [@attributes] = Array ( [version] = 1.0 ) [posts] => SimpleXMLElement Object ( [@attributes] => Array ( [type] => photo ) [post] => Array ( [0] => SimpleXMLElement Object ( [@attributes] => Array ( [id] => 574166180 [url] => http://young-n-reckless.tumblr.com/post/574166180 [url-with-slug] => http://young-n-reckless.tumblr.com/post/574166180 [type] => photo [date-gmt] => 2010-05-05 19:52:46 GMT [date] => Wed, 05 May 2010 15:52:46 [unix-timestamp] => 1273089166 [format] => html [reblog-key] => vc9EfT7d [slug] => [tumblelog] => young-n-reckless [bookmarklet] => true ) [tumblelog] => SimpleXMLElement Object ( [@attributes] => Array ( [title] => Young & Reckless [name] => young-n-reckless [url] => http://young-n-reckless.tumblr.com/ [timezone] => US/Eastern [avatar-url-16] => http://24.media.tumblr.com/avatar_424f776dd55c_16.png [avatar-url-24] => http://24.media.tumblr.com/avatar_424f776dd55c_24.png [avatar-url-30] => http://24.media.tumblr.com/avatar_424f776dd55c_30.png [avatar-url-40] => http://25.media.tumblr.com/avatar_424f776dd55c_40.png [avatar-url-48] => http://24.media.tumblr.com/avatar_424f776dd55c_48.png [avatar-url-64] => http://26.media.tumblr.com/avatar_424f776dd55c_64.png [avatar-url-96] => http://25.media.tumblr.com/avatar_424f776dd55c_96.png [avatar-url-128] => http://24.media.tumblr.com/avatar_424f776dd55c_128.png [avatar-url-512] => http://29.media.tumblr.com/avatar_424f776dd55c_512.png ) ) [photo-link-url] => http://www.flickr.com/photos/katiemabey/3429588812/ [photo-url] => Array ( [0] => http://30.media.tumblr.com/tumblr_l1w1qd7Zcg1qatgoto1_500.jpg [1] => http://30.media.tumblr.com/tumblr_l1w1qd7Zcg1qatgoto1_500.jpg [2] => http://25.media.tumblr.com/tumblr_l1w1qd7Zcg1qatgoto1_400.jpg [3] => http://28.media.tumblr.com/tumblr_l1w1qd7Zcg1qatgoto1_250.jpg [4] => http://30.media.tumblr.com/tumblr_l1w1qd7Zcg1qatgoto1_100.jpg [5] => http://30.media.tumblr.com/tumblr_l1w1qd7Zcg1qatgoto1_75sq.jpg ) ) Any help would be greatly appreciated, and thanks in advance.

• HTML entity encoding (convert '<' to '&lt;') on iPhone in objective-c

  - by Markus

  I'm developing an application for the iPhone that has inApp-mail sending capabilities. So far so good, but now I want to avoid html-injections as some parts of the mail are user-generated texts. Basically I search for something like this: // inits NSString *sourceString = [NSString stringWithString:@"Hello world! Grüße dich Welt <-- This is in German."]; // ----- THAT'S WHAT I'M LOOKING FOR // pseudo-code | // V NSString *htmlEncodedString = [sourceString htmlEncode]; // log NSLog(@"source string: %@", sourceString); NSLog(@"encoded string: %@", htmlEncodedString); Expected output source string: Hello world! Grüße dich Welt <-- This is in German. encoded string: Hello world! Gr&#252;&#223;e dich Welt &lt;-- This is in German. I already googled and looked through several of SO's questions and answers, but all of them seem to be related to URL-encoding and that's not what I really need (I tried stringByAddingPercentEscapesUsingEncoding with no luck - it creates %C3%BC out of an 'ü' that should be an ü). A code sample would be really great (correcting mine?)... -- Thanks in advance, Markus

• Is there a standard syntax for encoding structure objects as HTTP GET request parameters?

  - by lexicore

  Imagine we need to pass a a number structured objects to the web application - for instance, locale, layout settings and a definition of some query. This can be easily done with JSON or XML similar to the following fragment: <Locale>en</Locale> <Layout> <Block id="header">hide</Block> <Block id="footer">hide</Block> <Block id="navigation">minimize</Block> </Layout> <Query> <What>water</What> <When> <Start>2010-01-01</Start> </When> </Query> However, passing such structures with HTTP implies (roughly speaking) HTTP POST. Now assume we're limited to HTTP GET. Is there some kind of a standard solution for encoding structured data in HTTP GET request parameters? I can easily imagine something like: Locale=en& Layout.Block.header=hide& Layout.Block.footer=hide& Layout.Block.navigation=minimize& Query.What=water& Query.When.Start=2010-01-01 But what I'm looking for is a "standard" syntax, if there's any. ps. I'm surely aware of the problem with URL length. Please assume that it's not a problem in this case.

• Is it ethical to let users see the request headers from visitors to a url shortening service?

  - by soniiic

  I'm currently in the progress of making a url shortening service that will let the creator see the http request headers that the browser has made when visitors visit the url. The visitors won't be made aware that they are being tracked, but obviously nothing is personally identifiable. Is there anything I should be made aware of ethically or legally that makes this a bad idea?

• Mapstraction: Changing an Icon's image URL after it has been added?

  - by Paul Owens

  I am trying to use marker.setIcon() to change a markers image. However it appears that although this changes the marker.iconUrl attribute the icon itself is using marker.proprietary_marker.$.icon.image to display the markers image - so the markers icon remains unchanged. Is there a way to dynamically change the marker.proprietary_marker.$.icon.image? Add a marker. Check the icon's image url and the proprietary icon's image - they're the same. Change the icon. Again check the Urls. Now the Icon Url has changed but the marker still shows the old image which is in the proprietary marker object. <head> <title>Map Test</title> <script src="http://maps.google.com/maps?file=api&v=2&key=Your-Google-API-Key" type="text/javascript"></script> <script src="mapstraction.js"></script> <script type="text/javascript"> var map; var marker; function getMap(){ map = new mxn.Mapstraction('myMap','google'); map.setCenterAndZoom(new mxn.LatLonPoint(45.559242,-122.636467), 15); } function addMarker(){ marker = new mxn.Marker(new mxn.LatLonPoint(45.559242, -122.636467)); marker.addData({infoBubble : "Text", label : "Label", marker : 4, icon: "http://mapscripting.com/examples/mashups/richter-high.png"}); map.addMarker(marker); } function changeIcon(){ marker.setIcon("http://assets1.mapufacture.com/images/markers/usgs_marker.png"); } function showIconURL(){ alert(marker.iconUrl); } function showProprietaryIconURL(){ alert(marker.proprietary_marker.$.icon.image); } </script> </head> <body onload="getMap()"> <div id="myMap" style="width:627px; height:412px;"></div> <div> <input type="button" value="add marker" OnClick="addMarker();"> <input type="button" value="change icon" OnClick="changeIcon();"> <input type="button" value="show icon URL" OnClick="showIconURL();"> <input type="button" value="show proprierty icon URL " OnClick="showProprietaryIconURL();"> </div> </body> </html>
