• Static background noise while using new headset Ubuntu 13.04

  - by ThundLayr

  Today I bought a new gaming headset (Gx-Gaming Lychas), and when I tried to record some gameplay-comentary I noticed that there always is a static background noise, I just recorded an example so you guys can listen it (no downloaded needed): http://www47.zippyshare.com/v/65167832/file.html I'm using Kubuntu 13.04 and Kernel version is 3.8.0-19, my laptop is an Acer Travelmate 5760Z, I tried tons of configurations on Alsamixer and none of them made result, I really need to get this working so any kind of help will be very aprecciated. cat /proc/asound/cards: 0 [PCH ]: HDA-Intel - HDA Intel PCH

• Set form field values in ExtJS

  - by jeremib

  I'm using ExtJS to create a formPanel: new Ext.FormPanel({ labelAlign: 'top', title: 'Loading Contact...', bodyStyle:'padding:5px', width: 600, autoScroll: true, closable: true, items: [{ layout:'column', border:false, items:[{ columnWidth:.5, layout: 'form', border:false, items: [{ xtype:'textfield', fieldLabel: 'First Name', name: 'first_name', id: 'first_name', anchor:'95%' }, { xtype:'datefield', fieldLabel: 'Birthdate', name: 'birthdate', width: 150, }] },{ columnWidth:.5, layout: 'form', border:false, items: [{ xtype:'textfield', fieldLabel: 'Last Name', name: 'last_name', anchor:'95%' },{ xtype:'textfield', fieldLabel: 'Email', name: 'email', vtype:'email', anchor:'95%' }] }] },{ xtype:'tabpanel', plain:true, activeTab: 0, height:300, /* * By turning off deferred rendering we are guaranteeing that the * form fields within tabs that are not activated will still be * rendered. This is often important when creating multi-tabbed * forms. */ deferredRender: false, defaults:{bodyStyle:'padding:10px'}, items:[{ title:'Address', layout:'form', defaults: {width: 230}, defaultType: 'textfield', items: [{ fieldLabel: 'Line1', name: 'line1', allowBlank:false, },{ fieldLabel: 'Line2', name: 'line2', },{ fieldLabel: 'City', name: 'city', allowBlank: false, },{ xtype:"combo", fieldLabel:"State", name:"state", hiddenName:"combovalue" }, { fieldLabel: 'Zipcode', name: 'zipcode', allowBlank: false, }] },{ title:'Phone Numbers', layout:'form', defaults: {width: 230}, defaultType: 'textfield', items: [{ fieldLabel: 'Home', name: 'home_phone', },{ fieldLabel: 'Cell', name: 'cell_phone' },{ fieldLabel: 'Emergency', name: 'emergency_phone' }] },{ cls:'x-plain', title:'Notes', layout:'fit', items: { xtype:'htmleditor', name:'notes', fieldLabel:'Notes' } }] }], buttons: [{ text: 'Save' },{ text: 'Cancel' }] }) How do I access the form fields by the name to set their value manually? Thanks

• Can dummy objects be simulated on iphone?

  - by Mike

  I come from 3D animation and one of the basic things all 3D software have is the ability to create dummy objects. Dummy objects can be used to groups objects that can be rotated, moved or scaled together around a specific anchor point. This is the idea of what I am asking. Obviously we can have fake dummies by using a view and put other views as subviews, but this has problems as the view receives clicks and sometimes you don't want it to do so. You cannot change the anchorpoint of a view too. So, the dummies as I ask have, at least, these properties: adjustable anchor point it is not clickable it is totally invisible (cannot be rendered). any scale, rotation and translation of a dummy are propagated to the grouped objects considering the dummy's anchor point. it is totally animatable. Can this be simulated on iPhone? Is there any object that can be created to simulate this? thanks.

• Accessing ruby counter cache

  - by Julian

  Hi all, I'm playing around with a fork of acts_as_taggable_on_steroids as a learning exercise. The version I'm looking at does some stuff I don't understand to calculate Tag counts. So I thought I'd do a version using PORC (Plain Old Rails Counters): class Tagging < ActiveRecord::Base #:nodoc: belongs_to :tag, :counter_cache => "tagging_counter_cache" ... I thought tagging_counter_cache was transparently accessed when I access tag.taggings.count but apparently not? Do I really have to access tag.tagging_counter_cache explicitly? >> tag.taggings.count SQL (0.7ms) SELECT count(*) AS count_all FROM `taggings` WHERE (`taggings`.tag_id = 16) Same for size. It's cool if that's the case but just wanted to check.

• php curly braces groups

  - by David

  is there a function or regex or anything to group items by a { and } tag? so it should group items by the opening tag { and the closing tag }. but be careful, there are also groups inside parent groups like so: group { text1 group2 { text2 } } so basically think of it like php, you make an opening tag, you need to close it with a closing tag, curly braces in php's case. i just need it to like substr() each group into an associative array somehow, except I cant figure it out with the whole, "group inside a parent group".

• What is the most stupid coded solution you have read/improved/witnessed?

  - by Rigo Vides

  And for stupid I mean Illogical, non-effective, complex(the bad way), ugly code style. I will start: We had a requirement there when we needed to hide certain objects given the press of a button. So this framework we were using at the time provided a way to tag objects and retrieve all the objects with a certain tag in a complete iterable collection. So I presented the most logically solution given these conditions to my partner: Me: you know, tag all the objects we needed to hide with the same tag, then call the function to get them all, iterate trough them and make them hidden. Partner: I don't know, that is hardcoding for me... Me: So what do you suggest? 20 mins later... Partner: I don't know... let's put a tag to all the objects to be hidden like this, 1, 2, 3, 4, 5, 6, 7 (and so for each object to be hidden), Then we make a for from 1 to n (where n was the number of objects to hide) and we hide them all there!

• JavaScript check field value based on variable value

  - by Nikita Sumeiko

  I have an anchor like this: <a href="#" rel="1 4 7 18 ">Anchor</a> Where 'rel' attribute values are ids of some items. Than I have a form with an input, where user should type an id and click submit button. On submit button click I need to check the value of input like this: var value = $('a').attr('rel'); if ( value == '1' || value == '4' || value == '7' || value == '18') { // however I need the line above are created dynamically based on 'value' var alert('The id exists'); return false; } else { return true; } So, the question is how to create a line below dynamically based on anchor 'rel' attribute values?! This is the line: if ( value == '1' || value == '4' || value == '7' || value == '18') {

• Creating SparseImages for Pivot

  - by John Conwell

  Learning how to programmatically make collections for Microsoft Live Labs Pivot has been a pretty interesting ride. There are very few examples out there, and the folks at MS Live Labs are often slow on any feedback.  But that is what Reflector is for, right? Well, I was creating these InfoCard images (similar to the Car images in the "New Cars" sample collection that that MS created for Pivot), and wanted to put a Tag Cloud into the info card.  The problem was the size of the tag cloud might vary in order for all the tags to fit into the tag cloud (often times being bigger than the info card itself).  This was because the varying word lengths and calculated font sizes. So, to fix this, I made the tag cloud its own separate image from the info card.  Then, I would create a sparse image out of the two images, where the tag cloud fit into a small section of the info card.  This would allow the user to see the info card, but then zoom into the tag cloud and see all the tags at a normal resolution.  Kind'a cool. But...I couldn't find one code example (not one!) of how to create a sparse image.  There is one page on the SeaDragon site (http://www.seadragon.com/developer/creating-content/deep-zoom-tools/) that gives over the API for creating images and collections, and it sparsely goes over how to create a sparse image, but unless you are familiar with the API already, the documentation doesn't help very much. The key is the Image.ViewportWidth and Image.ViewportOrigin properties of the image that is getting super imposed on the main image.  I'll walk through the code below.  I've setup a couple Point structs to represent the parent and sub image sizes, as well as where on the parent I want to position the sub image.  Next, create the parent image.  This is pretty straight forward.  Then I create the sub image.  Then I calculate several ratios; the height to width ratio of the sub image, the width ratio of the sub image to the parent image, the height ratio of the sub image to the parent image, then the X and Y coordinates on the parent image where I want the sub image to be placed represented as a ratio of the position to the parent image size. After all these ratios have been calculated, I use them to calculate the Image.ViewportWidth and Image.ViewportOrigin values, then pass the image objects into the SparseImageCreator and call Create. The key thing that was really missing from the API documentation page is that when setting up your sub images, everything is expressed in a ratio in relation to the main parent image.  If I had known this, it would have saved me a lot of trial and error time.  And how did I figure this out?  Reflector of course!  There is a tool called Deep Zoom Composer that came from MS Live Labs which can create a sparse image.  I just dug around the tool's code until I found the method that create sparse images.  But seriously...look at the API documentation from the SeaDragon size and look at the code below and tell me if the documentation would have helped you at all.  I don't think so!   public static void WriteDeepZoomSparseImage(string mainImagePath, string subImagePath, string destination) {     Point parentImageSize = new Point(720, 420);     Point subImageSize = new Point(490, 310);     Point subImageLocation = new Point(196, 17);     List<Image> images = new List<Image>();     //create main image     Image mainImage = new Image(mainImagePath);     mainImage.Size = parentImageSize;     images.Add(mainImage);     //create sub image     Image subImage = new Image(subImagePath);     double hwRatio = subImageSize.X/subImageSize.Y;            // height width ratio of the tag cloud     double nodeWidth = subImageSize.X/parentImageSize.X;        // sub image width to parent image width ratio     double nodeHeight = subImageSize.Y / parentImageSize.Y;    // sub image height to parent image height ratio     double nodeX = subImageLocation.X/parentImageSize.X;       //x cordinate position on parent / width of parent     double nodeY = subImageLocation.Y / parentImageSize.Y;     //y cordinate position on parent / height of parent     subImage.ViewportWidth = (nodeWidth < double.Epsilon) ? 1.0 : (1.0 / nodeWidth);     subImage.ViewportOrigin = new Point(         (nodeWidth < double.Epsilon) ? -1.0 : (-nodeX / nodeWidth),         (nodeHeight < double.Epsilon) ? -1.0 : ((-nodeY / nodeHeight) / hwRatio));     images.Add(subImage);     //create sparse image     SparseImageCreator creator = new SparseImageCreator();     creator.Create(images, destination); }

• internet explorer 7 iframe unloads when going back

  - by André

  Hi this is my first post here, so please be kind ;-) i'm implementing a browser history manager, just like rsh or yui browser history manager. The idea was not to constantly poll the url hash of a hidden iframe, but to capture the onscroll event of an iframe, when it scrolls to an anchor name on an urlhashchange. So on every click i add an new anchor to iframe and set the iframe's hash to the anchors name. When pressing the back or forward button the frame scrolls to the previous or next anchor and the onscroll event is fired. That works great on firefox 3.0+, IE6 and Opera but on IE7 when hiting the back button the frame unloads and loses all its anchors. If anyone has an idea why this is happening or even a fix for this "bug", please i'm slowly going insane over this. thanks in advance btw the onscroll idea comes from: http://www.zachleat.com/web/2008/08/21/onhashchange-without-setinterval/

• My map callouts don't display the image when clicked

  - by Neelam Khan

  I am developing an iPhone application for a university project and I'm new to iPhone development. I have looked through Apple's MapCallouts code but it doesn't seem feasible to implement it. So far my code displays a map, drops annotations, displays the title and it displays the right call out button. But this is where I encounter problems. When I press on the callout button, it displays a blank view controller but it should display a different image for every callout that's tapped and this isn't happening so far. I have added my code below: - (void)mapView:(MKMapView *)mapView annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control { //NSUInteger tag = ((UIButton *)control).tag; if (self.detailController==nil) { DetailViewController* detailViewController = [[DetailViewController alloc] init]; [self.navigationController pushViewController:detailViewController animated:YES]; } // self.detailController.tag =1; //to identify image required // self.detailController.tag = tag; [self.navigationController pushViewController:detailController animated:YES]; }

• Get a specific entry by group in SQL

  Hi, I've a database who contain some datas in that form: icon(name, size, tag) (myicon.png, 16, 'twitter') (myicon.png, 32, 'twitter') (myicon.png, 128, 'twitter') (myicon.png, 256, 'twitter') (anothericon.png, 32, 'facebook') (anothericon.png, 128, 'facebook') (anothericon.png, 256, 'facebook') So as you see it, the name field is not uniq I can have multiple icons with the same name and they are separated with the size field. Now in PHP I have a query that get ONE icon set, for example : mysql_query("SELECT * FROM icon WHERE tag='".$tag."' ORDER BY size LIMIT 0, 10"); With this example if $tag contain 'twitter' it will show ONLY the first SQL data entry with the tag 'twitter', so it will be : (myicon.png, 16, 'twitter') This is what I want, but I would prefer the '128' size by default. Is this possible to tell SQL to send me only the 128 size when existing and if not another size ? Thanks !

• NSString simple pattern matching

  - by SirRatty

  Hi all, Mac OS 10.6, Cocoa project, 10.4 compatibility required. (Please note: my knowledge of regex is quite slight) I need to parse NSStrings, for matching cases where the string contains an embedded tag, where the tag format is: [xxxx] Where xxxx are random characters. e.g. "The quick brown [foxy] fox likes sox". In the above case, I need to grab the string "foxy". (Or nil if no tag is found.) Each string will only have one tag, and the tag can appear anywhere within the string, or may not appear at all. Could someone please help with a way to do that, preferably without having to include another library such as RegexKit. Thank you for any help.

• Intersection of sets Mongodb

  - by afvasd

  Hi everyone I am new to mongo, this is my db design: product := { name: str group: ref, comments: [ ref, ref, ref, ref ] } comments := { ... a bunch of comments stuff } tag := { _id: int, #Need this for online requests tag: str, products: [ {product: ref, score: float}, ... ], comments: [ {comment: ref, score: float}, ...], } So my usage pattern is: GIVEN a product, find comments that have certain tag and sort them accordingly. My current approach involves: Look for that tag object that has tag=myTag pull all the comments out, sorted look for that product where product.name=myProduct pull all the comments out (which are dbrefs by the way) loop through the result of 2, and checking if they are in 4, (this I can do a limit 10) etc. It's pretty inefficient. Any better methods?

• Changing the HTML of CKEditor form elements (in the dialog window)

  - by Kenny Meyers

  I'm trying to modify the HTML of the dialog boxes in CKEditor. The HTML inside each of those boxes is an absolute nightmare, and even worse, the source code is compressed and it's unclear what the path of execution is. I want to take something like this: <div class="cke_dialog_ui_select" id="44_uiElement" role="presentation"><label style="" for="42_select" id="43_label" class="cke_dialog_ui_labeled_label">Link Type</label><div role="presentation" class="cke_dialog_ui_labeled_content"><select aria-labelledby="43_label" class="cke_dialog_ui_input_select" id="42_select"><option value="url"> URL</option><option value="anchor"> Link to anchor in the text</option><option value="email"> E-mail</option></select></div></div> and turn it into something more legible and easier to style, removing one of the divs. These are for the Image and Anchor dialog boxes (Modal dialogues) respectively. Thanks for your help.

• Loading a DB table into nested dictionaries in Python

  - by Hossein

  Hi, I have a table in MySql DB which I want to load it to a dictionary in python. the table columns is as follows: id,url,tag,tagCount tagCount is the number of times that a tag has been repeated for a certain url. So in that case I need a nested dictionary, in other words a dictionary of dictionary, to load this table. Because each url have several tags for which there are different tagCounts.the code that I used is this:( the whole table is about 22,000 records ) cursor.execute( ''' SELECT url,tag,tagCount FROM wtp ''') urlTagCount = cursor.fetchall() d = defaultdict(defaultdict) for url,tag,tagCount in urlTagCount: d[url][tag]=tagCount print d first of all I want to know if this is correct.. and if it is why it takes so much time? Is there any faster solutions? I am loading this table into memory to have fast access to get rid of the hassle of slow database operations, but with this slow speed it has become a bottleneck itself, it is even much slower than DB access. and anyone help? thanks

• Validation errors from Google App Engine Logout link

  - by goggin13

  I am making a web page using the Google App Engine. I am validating my pages, and found that the logout link that is generated by the call to the users api (in python) users.create_logout_url(request.uri) does not validate as XHTML 1.0 Strict. The href in the anchor tag looks like this: /_ah/login?continue=http%3A//localhost%3A8080/&action=Logout Including a link with this anchor text throws three different validation errors: *general entity "action" not defined and no default entity *reference to entity "action" for which no system identifier could be generated *EntityRef: expecting ';' Here is a dummy page with the anchor tag in it, if you want to try it on w3c validator.Dummy Page. The logout link wont work, but you can see how the page is valid without it, but the actual text inside the href tag breaks the validation. Any thoughts on whats going on? Thank you!

"); while ($row = $db->sql_fetchrow($result)) { //fetching other $vars ---- $tags_id = explode(" ",$row['tags']); $c = count($tags_id); for($i=1;$i<$c-1;$i++){ list($tag_name,$slug) = $db->sql_fetchrow($db->sql_query( 'SELECT `tag`,`slug` FROM `bt_tags` WHERE `tid` = "'.tags_id[$i].'"

• How do I print the Images?

How do I get it to print out the image instead of giving me the image link.

• Has anyone seen this h:commandLink behavior?

  - by Liggy

  I have a very simple JSF form: <h:form id="simpleSearch"> <h:inputText id="surname" value="#{myBean.surname}" required="true" /> <h:commandLink>Search</h:commandLink> </h:form> When this page is rendered, the anchor that is generated looks like this (for brevity, I stripped out the generated onclick code): Search<a href="#" onclick="..."></a> As you can see, the "Search" is outside the anchor and the anchor body is empty. This is useless to me. I can't use this. Are there any suggestions/references/miracles out there to help me fix/understand what is going on here? Thanks!
