• Are there any configurable parameters to the gpsd?

  - by danatel

  I use the gpsd daemon with my application. Sometimes, the gpsd ceases to work with no apparent reason (clean sky). Even the gpsmon monitor shows no fix. Are there any parameters which must be set? Or is it a hardware problem? I am surprissed that many satellites are visible but the "Stat" bitmap does not contain the bit 7 - ephemeris data available. Should i somewhat pre-configure my position to allow for correct ephemeris data? Here is my gpsmon screen: 127.0.0.1:2947:/dev/ttyS3 SiRF binary> ^[[4~ -¦¦¦¦¦¦¦¦¦¦¦ X ¦¦¦¦¦¦ Y ¦¦¦¦¦¦ Z ¦¦¦¦¦¦¦¦¦¦ North ¦¦¦¦ East ¦¦¦¦¦ Alt ¦¦¦¦¦¦¦¦¦¬ -Pos: 3949260 1166016 4856299 m 49.89411° 16.44920° 1379 m - -Vel: 0.0 0.0 0.0 m/s 0.0 0.0 0.0 climb m/s- -Week+TOW:1578+224837.06 Day: 2 14:27:17.06 Heading: 0.0° 0.0 speed m/s- -Skew: -13.025817 TZ: -7200 HDOP: 0.0 M1:00 M2: 00 - -Fix: 0 = - L¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦ Packet type 2 (0x02) ¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦- -¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¬-¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¦¬ -Ch PRN Az El Stat C/N ?

• jquery ui dialog and our dearest friend, ie6

  - by bradjive

  I'm using the jquery ui dialog for a modal popup dialog. It's working great in Firefox/Chrome but terrible in ie6. Problem: When I show the dialog in ie6, the browser window grows and automatically scrolls down to the bottom. The height increase and automatic scroll-down is equal to the height of the jquery dialog. I can scroll up and then use the dialog as normal, but the behavior where it grows the window and drops is maddeningly unacceptable. Here is how I'm launching the window: <div id="dialogWindow"></div> ... $(document).ready(function() { var $dialog = $("#dialogWindow").dialog({ autoOpen: false, modal: true, minWidth: 560, width: 560, resizable: "true", position: "top" }); $('.addButton').click(function(e) { e.preventDefault(); $('#dialogWindow').load('http://myurl'); $dialog.dialog('open'); }); }); I am already using the bgiframe plugin for jquery which is key for ie6 overlay issues. But this seems unrelated to that. Has anyone seen this before and found a work around?

• CSS being ignored in IE & FFox but not Chrome

  - by Grant

  Hi, i am styling a navigation menu using the following css. I have found that it works perfectly in chrome but absolutely none of the css is beign applied in firefox or IE. Is there something obvious that i havent done or have done here? <style type="text/css"> #ddm { margin: 0; padding: 0; } #ddm li { float: left; list-style: none; font: 8pt Tahoma, Geneva, sans-serif; } #ddm li a { display: block; padding: 5px 12px; text-decoration: none; border-right: 1px solid white; width: 70px; white-space: nowrap; color:Red; border: none; } #ddm li a:hover { color:White; background-color:#444444; } #ddm li ul { margin: 0; padding: 0; position: absolute; visibility: hidden; } #ddm li ul li { float: none; display: inline } #ddm li ul li a { width: auto; } #ddm li ul li a:hover { } </style> <ul id="ddm"> <li> <ul> <li><a href="#">test 1</a></li> <li><a href="#">test 2</a></li> </ul> </li> </ul>

• Getting Depth Value on Kinect SDK 1.6

  - by AlexanderPD

  this is my first try on Kinect and Kinect SDK so I'm having a lot of "newbie issues" :) my goal is to point my mouse on the Kinect standard video output and get the depth value. I already have both normal video and depth video outputs by using the 2 "Color Basic-WPF" and "Depth Basic-WPF" samples, and handling mouse events or position is not a problem. In fact i already did all and i already got a depth value, but this value is always HIGHLY imprecise. It jumps from 500 to 4000 by just moving to the next pixel in a plane surface. So.. I'm pretty sure I'm reading the depth value in the wrong way. This is how i read it: short debugValue = depthPixels[x*y].Depth; debug.Text = "X = "+x+", Y = "+y+", value = "+debugValue.ToString(); i know it's pretty out of context, this little piece of code is inside the same SensorDepthFrameReady function in "Depth Basic-WPF"! "x" and "y" are the mouse coordinates and depthPixels is DepthImagePixel[] type, a temporary array filled with the "depthFrame.CopyDepthImagePixelDataTo(this.depthPixels);" instruction. Depth frame is filled here: DepthImageFrame depthFrame = e.OpenDepthImageFrame() the "e" comes from here: private void SensorDepthFrameReady(object sender, DepthImageFrameReadyEventArgs e) and this last one is called here: this.sensor.DepthFrameReady += this.SensorDepthFrameReady; how i must handle that depth value i get? I know the value must be between 800 and 4000 but i get values between about 500 and about 8000. i already google a lot (here on SO too) and i still can't understand if the depth value is 11 or 13 bit. The sdk examples uses shrink this value to 8 bit and this is making even more confusion in my head :(

• XSLT inserting once off custom text

  - by BeraCim

  Hi all: The folloiwng is a pre-existing xml file. I was wondering how can I insert a element before the first element using xslt? <XmlFile> <!-- insert another <tag> element here --> <tag> <innerTag> </innerTag> </tag> <tag> <innerTag> </innerTag> </tag> <tag> <innerTag> </innerTag> </tag> </XmlFile> I was thinking of using a for-each loop and test the position = 0, but upon the first occurence of the for-each its already too late. This is a once-off text so I can't combine it with other xslt templates that are already inside the xsl file. Thanks.

• Why doesn't this jQuery snippet work in IE8 like it does in Firefox or Chrome (Live Demo Included) ?

  - by Siracuse

  I asked for help earlier on Stackoverflow involving highlighting spans with the same Class when a mouse hovers over any Span with that same Class. It is working great: http://stackoverflow.com/questions/2709686/how-can-i-add-a-border-to-all-the-elements-that-share-a-class-when-the-mouse-has $('span[class]').hover( function() { $('.' + $(this).attr('class')).css('background-color','green'); }, function() { $('.' + $(this).attr('class')).css('background-color','yellow'); } ) Here is an example of it in usage: http://dl.dropbox.com/u/638285/0utput.html However, it doesn't appear to work properly in IE8, while it DOES work in Chrome/Firefox. Here is a screenshot of it in IE8, with my mouse hovered over the " min) { min" section in the middle. As you can see, it highlighted the span that the mouse is hovering over perfectly fine. However, it has also highlighted some random spans above and below it that don't have the same class! Only the span's with the same Class as the one where the mouse is over should be highlighted green. In this screenshot, only that middle green section should be green. Here is a screenshot of it working properly in Firefox/Chrome with my mouse in the exact same position: This screenshot is correct as the span that the mouse is over (the green section) is the only one in this section that shares that class. Why is IE8 randomly green-highlighting spans when it shouldn't be (they don't share the same class) using my little jQuery snippet? Again, if you want to see it live I have it here: http://dl.dropbox.com/u/638285/0utput.html

• MediaFileUpload of HTML in UTF-8 encoding using Python and Google-Drive-SDK

  - by Victoria

  Looking for example using MediaFileUpload has a reference to the basic documentation for creating/uploading a file to Google Drive. However, while I have code that creates files, converting from HTML to Google Doc format. It works perfectly when they contain only ASCII characters, but when I add a non-ASCII character, it fails, with the following traceback: Traceback (most recent call last): File "d:\my\py\ckwort.py", line 949, in <module> rids, worker_documents = analyze( meta, gd ) File "d:\my\py\ckwort.py", line 812, in analyze gd.mkdir( **iy ) File "d:\my\py\ckwort.py", line 205, in mkdir self.create( **( kw['subop'])) File "d:\my\py\ckwort.py", line 282, in create media_body=kw['media_body'], File "D:\my\py\gdrive2\oauth2client\util.py", line 120, in positional_wrapper return wrapped(*args, **kwargs) File "D:\my\py\gdrive2\apiclient\http.py", line 676, in execute headers=self.headers) File "D:\my\py\gdrive2\oauth2client\util.py", line 120, in positional_wrapper return wrapped(*args, **kwargs) File "D:\my\py\gdrive2\oauth2client\client.py", line 420, in new_request redirections, connection_type) File "D:\my\py\gdrive2\httplib2\__init__.py", line 1597, in request (response, content) = self._request(conn, authority, uri, request_uri, method, body, headers, redirections, cachekey) File "D:\my\py\gdrive2\httplib2\__init__.py", line 1345, in _request (response, content) = self._conn_request(conn, request_uri, method, body, headers) File "D:\my\py\gdrive2\httplib2\__init__.py", line 1282, in _conn_request conn.request(method, request_uri, body, headers) File "C:\Python27\lib\httplib.py", line 958, in request self._send_request(method, url, body, headers) File "C:\Python27\lib\httplib.py", line 992, in _send_request self.endheaders(body) File "C:\Python27\lib\httplib.py", line 954, in endheaders self._send_output(message_body) File "C:\Python27\lib\httplib.py", line 812, in _send_output msg += message_body UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 370: ordinal not in range(128) I don't find any parameter to use to specify what file encoding should be used by MediaFileUpload (My files are using UTF-8).

• jQuery image hover color overlay

  - by Ryan Max

  I can't seem to find any examples of this having been done anywhere on the internet before but here is what I am going to attempt to do...I'm trying to go about the cleanest possible way of laying this out. So I have an image gallery where the images are all different sizes. I want to make it so that when you mouseover the image, it turns a shade of orange. Just a simple hover effect. I want to do this without using an image swap, otherwise I'd have to create an orange colored hover-image for each individual gallery image, I'd like this to be a bit more dynamic. My plan is just to position an empty div over the image absolutely with a background color, width and height 100% and opacity: 0. Then using jquery, on mouseover I'd have the opacity fade to 0.3 or so, and fade back to zero on mouseout. My question is, what would be the best way to layout the html and css to do this efficiently and cleanly. Here's a brief, but incomplete setup: <li> <a href="#"> <div class="hover">&nbsp;</div> <img src="images/galerry_image.png" /> </a> </li> .hover { width: 100%; height: 100%; background: orange; opacity: 0; }

• Copy Small Bitmaps on to Large Bitmap with Transparency Blend: What is faster than graphics.DrawImag

  - by Glenn

  I have identified this call as a bottleneck in a high pressure function. graphics.DrawImage(smallBitmap, x , y); Is there a faster way to blend small semi transparent bitmaps into a larger semi transparent one? Example Usage: XY[] locations = GetLocs(); Bitmap[] bitmaps = GetBmps(); //small images sizes vary approx 30px x 30px using (Bitmap large = new Bitmap(500, 500, PixelFormat.Format32bppPArgb)) using (Graphics largeGraphics = Graphics.FromImage(large)) { for(var i=0; i < largeNumber; i++) { //this is the bottleneck largeGraphics.DrawImage(bitmaps[i], locations[i].x , locations[i].y); } } var done = new MemoryStream(); large.Save(done, ImageFormat.Png); done.Position = 0; return (done); The DrawImage calls take a small 32bppPArgb bitmaps and copies them into a larger bitmap at locations that vary and the small bitmaps might only partially overlap the larger bitmaps visible area. Both images have semi transparent contents that get blended by DrawImage in a way that is important to the output. I've done some testing with BitBlt but not seen significant speed improvement and the alpha blending didn't come out the same in my tests. I'm open to just about any method including a better call to bitblt or unsafe c# code.

• How do you make a static sprite be a child of another sprite in cocos2D while using SpaceManager

  - by JJBigThoughts

  I have two static (STATIC_MASS) SpaceManager sprites. One is a child of the other - by which I mean that one sort of builds up the other one, but although the child's images shows up in the right place, the child doesn't seem to exists in the chipmunk physics engine, like I would expect. In my case, I have a backboard (rectangular sprite) and a hoop (a circular sprite). Since I might want to move the backboard, I'd like to attach the hoop to backboard so that the hoop automatically moves right along with the backboard. Here, we see a rotating backboard with attached hoop. It looks OK on the screen, but other objects only bounce off the backboard but pass right through the hoop (in a bad sense of the term). What doesn't my child sprite seem to exist in the physics engine? // Add Backboard cpShape *shapeRect = [smgr addRectAt:cpvWinCenter mass:STATIC_MASS width:200 height:10 rotation:0.0f ];// We're upgrading this cpCCSprite * cccrsRect = [cpCCSprite spriteWithShape:shapeRect file:@"rect_200x10.png"]; [self addChild:cccrsRect]; // Spin the static backboard: http://stackoverflow.com/questions/2691589/how-do-you-make-a-sprite-rotate-in-cocos2d-while-using-spacemanager // Make static object update moves in chipmunk // Since Backboard is static, and since we're going to move it, it needs to know about spacemanager so its position gets updated inside chipmunk. // Setting this would make the smgr recalculate all static shapes positions every step // cccrsRect.integrationDt = smgr.constantDt; // cccrsRect.spaceManager = smgr; // Alternative method: smgr.rehashStaticEveryStep = YES; smgr.rehashStaticEveryStep = YES; // Spin the backboard [cccrsRect runAction:[CCRepeatForever actionWithAction: [CCSequence actions: [CCRotateTo actionWithDuration:2 angle:180], [CCRotateTo actionWithDuration:2 angle:360], nil] ]]; // Add the hoop cpShape *shapeHoop = [smgr addCircleAt:ccp(100,-45) mass:STATIC_MASS radius: 50 ]; cpCCSprite * cccrsHoop = [cpCCSprite spriteWithShape:shapeHoop file:@"hoop_100x100.png"]; [cccrsRect addChild:cccrsHoop]; This is only half working for me. Note: SpaceManager is a toolkit for working with cocos2D-iphone

• Voting on Hacker News stories programmatically?

  - by igorgue

  I decided to write an app like: http://michaelgrinich.com/hackernews/ but for Android devices, my idea will use a web application backend (because I rather code in Python and for the web than completely in Java for Android devices). What I have right now implemented is something like this: $ curl -i http://localhost:8080/stories.json?page=1\&stories=1 HTTP/1.0 200 OK Date: Sun, 25 Apr 2010 07:59:37 GMT Server: WSGIServer/0.1 Python/2.6.5 Content-Length: 296 Content-Type: application/json [{"title": "Don\u2019t talk to aliens, warns Stephen Hawking", "url": "http://www.timesonline.co.uk/tol/news/science/space/article7107207.ece?", "unix_time": 1272175177, "comments": 15, "score": 38, "user": "chaostheory", "position": 1, "human_time": "Sun Apr 25 01:59:37 2010", "id": "1292241"}] The next step (and final I think) is voting, my design is doing something like this: $ curl -i http://localhost:8080/stories/1?vote=up -u username:password Will vote up and: $ curl -i http://localhost:8080/stories/1?vote=down -u username:password Down. I have no idea how to do it though... I was planning to use Twill but the login link is always different, e.g.: http://news.ycombinator.com/x?fnid=7u89ccHKln Later the Android app will consume this API. Any experience with programmatically browsing Hacker News?

• How to show jQuery is working/waiting/loading ?

  - by Kim

  How do I show a loading picture and/or message to the user ? If possible, would I like to know how to make it full screen with grey-dimmed background. Kinda like when viewing the large picture from some galleries (sorry, no example link). Currently do I add a CSS class which has the image and other formating, but its not working for some reason. Results from the search do get inserted into the div. HTML <div id="searchresults"></div> CSS div.loading { background-image: url('../img/loading.gif'); background-position: center; width: 80px; height: 80px; } JS $(document).ready(function(){ $('#searchform').submit(function(){ $('#searchresults').addClass('loading'); $.post('search.php', $('#'+this.id).serialize(),function(result){ $('#searchresults').html(result); }); $('#searchresults').removeClass('loading'); return false; }); });

• Modify Jquery UI slider control

  - by Jean-Yves Deman

  I use the Jquery UI slider control. My slider has a width of 200px. I would like the center of my left handle is shifted 14px to the right and the center of my right handle is offset to the left of 14px. So, my good slider will more than 172px (200-14-14). The background-image measure good 200px. The length of 14px is calculated as follows: width of the handle (28px) / 2. Can you help me solve this mystery? Thank you in advance. .ui-slider .ui-slider-handle { width:28px; height:28px; background:url(images/bulle.png) no-repeat 0 0; overflow: hidden; position:absolute; margin-left:0px; top: -7px; border-style:none; cursor:help; }? I use "margin-left:0px;" to delete the "margin-left:-14px" by default. But, my right handle spring 28px to the right ! Help me please !

• CSS3 animations - how to make different animations to different elements on scroll

  - by DeanDeey

  I have a question about the doing CSS3 animations on scroll.. I found a code, that shows the DIV element after the user scrolls down: <script type="text/javascript"> $(document).ready(function() { /* Every time the window is scrolled ... */ $(window).scroll( function(){ /* Check the location of each desired element */ $('.hideme').each( function(i){ var bottom_of_object = $(this).position().top + $(this).outerHeight(); var bottom_of_window = $(window).scrollTop() + $(window).height(); /* If the object is completely visible in the window, fade it it */ if( bottom_of_window > bottom_of_object ){ $(this).animate({'opacity':'1'},500); } }); }); }); </script> I'm building a site, which one will have about 5 different boxes, which one will be shown when the user scrolls down to each box. But my question is, how i make the animation inside those boxes. Foe example: in each box there is title, content and images. How do i make all the elements appear after each other, because with this code all the class elements are shown at once. But i would like that if user scrolls down, first the tittle appears, then the content and at the end the images. And then when user scrolls to the next box, the same process repeat's itself. I use some CSS3 delays, but in this case i don't know how long will user take to scroll down. thanks!

• Handle row deletion in UITableViewController

  - by Kamchatka

  Hello, I hava a UINavigationController. The first level is a UITableViewController, the second level just shows details on one of the items of the table view. In this detail view, I can delete the item. It deletes the underlying managed object. When I pop back to the view, I have a crash. I understand why, it's because I didn't update the cached array that contains the data. I looked at several tutorials and I don't exactly understand how am I supposed to handle deletion. Maybe I don't understand exactly where I should fetch the objects in the model. Should I do a query for every cellForRowAtIndexPath and take the item in the result at position indexPath.row? It doesn't look efficient. Should I check for changes somewhere and recache the whole query in an array. I would think CoreData would provide something more natural but I couldn't find it so far. Thanks in advance.

• How do I search for a string with quotes?

  - by every_answer_gets_a_point

• CSS Multiple multi-column divs

  - by accelerate

  I have a bunch of items (text, image, mixed content, etc) that I want to display. The user can define what row and what column that item appears in. For example, in row 1, there could be two items/columns, both images. In row two, there could be three items / columns, one with an image, two others as pure text. Oh, and the user may specify the width of any particular column/image/item. I have a solution that uses multiple tables that works. In essence, each row is a new table. This works for the most part. I'm wondering if I can use just divs? Now my CSS foo is lacking, and I tried to copy examples from the web, and I haven't been able to get it working. Right now I have something like this: `[for each row] [for each column] [content] ` But everything is overlapping each other. I've also tried using "position: relative", but things look even more borked. So can divs actually be used for multiple rows and different number of columns?

• CSS column height different on Opera/IE to FF

  - by Infiniti Fizz

  Hi all, Thanks to everyone who helped with my last question but I've got a new browser-independent problem: For some reason, the image navigator (not yet functioning) on a website I'm working on is currently not displaying in the correct place on Firefox. It appears in the right place in IE8 and Opera but Firefox seems to have a problem with it. As can be seen in the below image, the imageContainer div (the image and the left/right arrows) appears on top of the footer, this is how it should look i.e. how it looks in IE8 and Opera. But in the image below, the imageContainer div is cutting into the footer div for some reason, and I don't know why. imageContainer has a margin-top: 110px; to get it in the right place at the bottom of its column. There are 2 columns, the left housing the paragraphs and imageContainer and the right housing the Calendar and contact details. The footer div also has clear: both; Also, it's not just the image that is falling into the footer, it's the arrows as well only they are the same colour as the footer so this isn't immediately apparent. Any ideas why it isn't displaying correctly? Is there a better way of aligning the imageContainer to the bottom of it's column (to keep the box shape of the website) other than using the margin-top to position it? Thanks in advance, infinitifizz

• C# Process Binary File, Multi-Thread Processing

  - by washtik

  I have the following code that processes a binary file. I want to split the processing workload by using threads and assigning each line of the binary file to threads in the ThreadPool. Processing time for each line is only small but when dealing with files that might contain hundreds of lines, it makes sense to split the workload. My question is regarding the BinaryReader and thread safety. First of all, is what I am doing below acceptable. I have a feeling it would be better to pass only the binary for each line to the PROCESS_Binary_Return_lineData method. Please note the code below is conceptual. I looking for a but of guidance on this as my knowledge of multi-threading is in its infancy. Perhaps there is a better way to achieve the same result, i.e. split processing of each binary line. var dic = new Dictionary<DateTime, Data>(); var resetEvent = new ManualResetEvent(false); using (var b = new BinaryReader(File.Open(Constants.dataFile, FileMode.Open, FileAccess.Read, FileShare.Read))) { var lByte = b.BaseStream.Length; var toProcess = 0; while (lByte >= DATALENGTH) { b.BaseStream.Position = lByte; lByte = lByte - AB_DATALENGTH; ThreadPool.QueueUserWorkItem(delegate { Interlocked.Increment(ref toProcess); var lineData = PROCESS_Binary_Return_lineData(b); lock(dic) { if (!dic.ContainsKey(lineData.DateTime)) { dic.Add(lineData.DateTime, lineData); } } if (Interlocked.Decrement(ref toProcess) == 0) resetEvent.Set(); }, null); } } resetEvent.WaitOne();

• How to apply CSS theme to only a specific jQuery-UI element?

  - by Thierry-Dimitri Roy

  I have a web site already build with my own CSS theme. I'm using jQuery UI "tabs" widget but no CSS from jQuery-UI. Now, I'm trying to add the "Date Picker" widget in one of my page. It would be great if I could reuse jQuery-UI default theme which is just fine. The problem is that the date picker theme is also applied to my tabs CSS. For example the "ui-widget" css properties is applied to both date picker and tabs elements. I can't seem to find a way to apply the css properties to only the date picker. I can't see a "super selector" that only applies to the date picker DIV. What would be the best way to handle this? [EDIT] The datepicker widget is really the problem. I cannot apply CSS style specific to it. Here is the starting code of the DIV that get pops up: <div style="position: absolute; top: 300.4px; left: 149px; display: block;" id="ui-datepicker-div" class="ui-datepicker ui-widget ui-widget-content ui-helper-clearfix ui-corner-all ui-helper-hidden-accessible"><div class="ui-datepicker-header ui-widget-header ui-helper-clearfix ui-corner-all"> As such, I cannot add a super selector. What would be great would be that the date picker widget supports CSS scope. But it does not. I'm stuck manually editing the jQuery CSS file. The Date Picker is currently being refactored. Hopefully the new code will address this issue.
