• PhysX Question about Raycasting - Setting the shape masks

  - by sweet tv

  I am trying to make the raycast give me the distance of the terrain and nothing else. But I'm not sure how to use the group Mask Filter. virtual NxShape* raycastClosestShape (const NxRay& worldRay, NxShapesType shapeType, NxRaycastHit& hit, NxU32 groups=0xffffffff, NxReal maxDist=NX_MAX_F32, NxU32 hintFlags=0xffffffff, const NxGroupsMask* groupsMask=NULL, NxShape** cache=NULL) const = 0; \param[in] groups Mask used to filter shape objects. Let's say my terrain is set in group 1. How would I use the function above?

Shoutouts: In with the links I've listed below, Sigurd Snørteland also sent a link to this app he's working on which is actually pretty cool to see: ZuneLight. The code is not yet available. He also has a no-code demo of a Silverlight Media Center Pieter Voloshyn, Luiz Thadeu, and Jhun Iti have a very nice Silverlight image editor up: Thumba From SilverlightCream.com: WP7 - Silverlight on mobile Sigurd Snørteland submitted some links for me that have been translated to English from his blog. I hope the pages come out good because he's got a lot of good stuff on there. This one has a link to a presentation he did, and 4 projects you can load up in the emulator that he's converted to the phone: weather, worldclock, coverflow, and solitaire ... pretty cool... thanks for the links Sigurd! Understanding Page Orientation in Silverlight for Windows Phone Jeff Prosise has a really nice post up on page orientation in WP7 ... what it means to your app, how to detect it, and example code for what to do then... also love a quote by Jeff: "Silverlight for Windows Phone is the hottest thing since color TV" Why you should check out Expression Blend Behaviors when using Silverlight DaveDev has a post up describing Behaviors and why we should use them, plus tons of external links to resources, blogs, videos... all good stuff... Fiddler inspector for WCF Silverlight Polling Duplex and WCF RIA Joe Zhou announces and provides a link to a new Fiddler inspector that understands the framing in Polling Duplex and also raw binary xml and binary SOAP.

John Papa and Adam Kinney are discussing the PathListBox and looking at some cool demos thereof. Exposing SOAP, OData, and JSON Endpoints for RIA Services (Silverlight TV 26) Since today IS Thursday, we have a new Silverlight TV, number 26, and John Papa is chatting with Deepesh Mohnani of the WCF RIA Services team about exposing all sorts of endpoints... should be something in there for everybody :) Workaround for a Silverlight data binding bug affecting various scenarios - including DataGrid+ContextMenu David Anson details the rabbit-trail he and others on the team followed in response to a problem reported via Twitter where the binding on a DataGrid seemed off by a row(!) ... weird but true, validated, and SL3/4 are bug-for-bug compatible with this too! ... But David wouldn't leave us there.. he also has a workaround. Sharing the code for a simple Silverlight 4 REST-based cloud-oriented file management app for Azure and S3 David Anson had an opportunity to build an app he's wanted to build for a while and shares it with us: Blobstore -- a small, lightweight Silverlight 4 application that acts as a basic front-end for the Windows Azure Simple Data Storage and the Amazon Simple Storage Service (S3) -- and remember I said he shared the source :) Stay in the 'Light!

• Help with Android LinearLayout or RelativeLayout

  - by PeEll

  I need to create two views programmatically (because I need to access the ondraw of one of the views). For some reason, no matter what I do to add the views to the contentview, they don't show up vertically stacked, one below the other. I can do it just fine using the XML using a RelativeLayout and layout positioning, but with the XML I can't create a view object and overload the ondraw method. What am I doing wrong with the programmatic approach, and how do I solve this problem? LinearLayout mLinearLayout; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Create a LinearLayout in which to add the ImageView mLinearLayout = new LinearLayout(this); TextView tv = new TextView(this); tv.setBackgroundColor(0xff333333); tv.setText("Enter your member number:"); tv.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT)); DrawableView i = new DrawableView(this); i.layout(0,40,0,0); i.setLayoutParams(new Gallery.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); mLinearLayout.addView(tv); mLinearLayout.addView(i,300,300); setContentView(mLinearLayout); }

• problem in loading images from web

  - by Lynnooi

  hi, I am new in android and had developed an app which get images from the website and display it. I got it working in emulator but not in real phones. In some device, it will crash or take very long loading period. Can anyone please help me or guide me in improving it as i'm not sure whether the way i loads the images is correct or not.

• Does all the network card use the same frequency to send signals to wire?

  - by smwikipedia

  Hi, I am comparing my cable TV wire to my network wire. In a TV cable wire, different frequencies are used by different TV channels. And since a certain channel use a fixed frequency, I think the only left way to represent different signal is with the carrier wave's amplitude. But what about the network wire? For all the network card with the same type, do they also use different frequencies to send signals just like TV cable? I vaguely remember that they use frequency adjustment to represent signals. So the frequency should not be a fixed one. So how did all the network cards that sharing the same medium differentiate their own signal from others?

• Android phones: how does the video out feature work?

  - by confusedKid

  Hi, I'm searching for android phones that can use video out to the tv for a research project. I'm considering the HTC Touch Pro. Is there anything I have to do specifically to get the video out to work (for displaying my app on the tv)? or will the phone just display a running app on the tv without extra work? Thanks, I hope the post made sense =)

• Add "My Dropbox" to Your Windows 7 Start Menu

  - by The Geek

  Over here at How-To Geek, we’re huge fans of Dropbox, the amazingly fast online file sync utility, but we’d be even happier if we could natively add it to the Windows 7 Start Menu, where it belongs. And today, that’s what we’ll do. Yep, that’s right. You can add it to the Start Menu… using a silly hack to the Libraries feature and renaming the Recorded TV library to a different name. It’s not a perfect solution, but you can access your Dropbox folder this way and it just seems to belong there. First things first, head into the Customize Start Menu panel by right-clicking on the start menu and using Properties, then make sure that Recorded TV is set to “Display as a link”. Next, right-click on Recorded TV, choose Rename, and then change it to something else like My Dropbox.   Now you’ll want to right-click on that button again, and choose Properties, where you’ll see the Library locations in the list… the general idea is that you want to remove Recorded TV, and then add your Dropbox folder. Oh, and you’ll probably want to make sure to set “Optimize this library for” to “General Items”. At this point, you can just click on My Dropbox, and you’ll see, well, Your Dropbox! (no surprise there). Yeah, I know, it’s totally a hack. But it’s a very useful one! Also, if you aren’t already using Dropbox, you should really check it out—2 GB for free, accessible via the web from anywhere, and you can sync to multiple desktops.

  I have Radeon card connected over HDMI to my TV. To resolve bug with HDMI-sound, I switch between virtual terminal and GNOME desktop each time the TV is switched on with CTRL+ALT+F1 and after console appear with CTRL+ALT+F7. It's ugly, but its worked for me. Since yesterday I got system freezes on CTRL+ALT+F1 - no reaction on keyboard, mouse pointer disappear at all, GNOME desktop still displayed. Probably has nothing to do with HDMI. Any suggestion how to resolve it?

• Geforce GT240M: How to disable Notebook screen and enable external Monitor

  When i attach my Notebook (Nvidia Geforce GT 240M) to my Panasonic-TV via HDMI, both screens are activated. I use Nvidia-Driver Version 260.19.06. I wonder how to deactivate my notebook display automatically or with one Script and switch to the external Monitor when attached. The TV needs an overscan-correction of 100px to display the whole screen. I also want to close the notebook without deactivating the external monitor, what still happens now. Is this possible?

• Win7 playback of dvr-ms files stutters

  - by Jim Lynn

  I've just had to install Windows 7 on my Media Center machine because my Vista installation had a faulty drive. I've got the latest drivers that I can find - Intel 945GM integrated Graphics, Realtek audio drivers. Things are working OK with one exception. Playback of old recordings, from dvr-ms format files, is choppy. The picture freezes for a fraction of a second, then quickly catches up. The sound is uninterrupted and doesn't pause. These freezes happen once every 5 seconds or so. It's very regular. Playback of Live TV from the digital tuner is perfectly smooth. DVD playback is perfectly smooth. As an experiment, I used the MPEG editing package VideoReDo to create a small test file in three different formats. This program takes the raw MPEG streams and repackages them into the desired container. I took the same clip and created three files in three formats: dvr-ms (Microsoft's old recorded TV format); mpg (standard MPEG); and ts (raw MPEG transport stream of the kind often produced by PVRs). When these three files are played back under Windows 7, the mpg and ts files play smoothly, but the dvr-ms file stutters. The last piece of data I have is that two other Windows 7 machines can play back dvr-ms files smoothly with no stuttering. One is a netbook, with less grunt than the media centre. So there must be something specific about my Media Center machine that's causing the problem. Does anyone have any idea where I can look now? I don't know much about AV software, codecs, filter graphs etc. but I suspect that's where the problem lies. Rendering the video isn't the problem, but extracting the streams is. How would I go about diagnosing the problem? Edited to add: I just used the GraphStudio tool to look at the filter graph on the offending PC. The filter graph it uses by default for dvr-ms looks identical to the other machines, and, interestingly, when I play the files using GraphStudio they run smoothly. Under Windows Media Player and Windows Media Center they stutter. I'd like to see the filter graph for WMP but GraphStudio won't show it. It looks like WMP and WMC are using a different decoding path to GraphStudio. Edited again to add: Today I purchased a new HDTV. The same Media Center driving the TV at 1080p is now playing back the old Recorded TV files smoothly, without stuttering. So whatever the cause of the original problem, using a different resolution seems to have removed the problem. It might also explain why nobody else has had this problem. I doubt many people use Media Centre with a 14in portable TV.

• Triple monitor setup in linux

  - by Brendan Abel

  I'm hoping there are some xorg gurus out there. I'm trying to get a three monitor setup working in linux. I have 2 lcd monitors and a tv, all different resolutions. I'm using 2 video cards; a 9800 GTX and 7900Gt. I've seen a lot of different posts about people trying to make this work, and in every case, they either gave up, or Xinerama magically solved all their problems. Basically, my main problem is that I cannot get Xinerama to work. Every time I turn it on in the options, my machine gets stuck in a neverending boot cycle. If I disable Xinerama, I just have three Xorg screens, but I can't drag windows from one to the other. I can get the 2 lcds on Twinview, and the tv on a separate Xorg screen no problem. But I don't really like this solution. I'd rather have them all on separate screens and stitch them together with Xinerama. Has anyone done this? Here's my xorg.conf for reference. p.s. This took me all of 30 seconds to set up in Windows XP! p.s.s. I've seen somewhere that maybe randr can solve my problems? But I'm not quite sure how?

Under Windows Media Player and Windows Media Center they stutter. I'd like to see the filter graph for Windows Media Player but GraphStudio won't show it. It looks like Windows Media Player and WMC are using a different decoding path to GraphStudio. Edited again to add: Today I purchased a new HDTV. The same Media Center driving the TV at 1080p is now playing back the old Recorded TV files smoothly, without stuttering. So whatever the cause of the original problem, using a different resolution seems to have removed the problem. It might also explain why nobody else has had this problem. I doubt many people use Media Centre with a 14in portable TV.

• Triple monitor setup in linux

  - by Brendan Abel

  I'm hoping there are some xorg gurus out there. I'm trying to get a three monitor setup working in linux. I have 2 lcd monitors and a tv, all different resolutions. I'm using 2 video cards; a 9800 GTX and 7900Gt. I've seen a lot of different posts about people trying to make this work, and in every case, they either gave up, or Xinerama magically solved all their problems. Basically, my main problem is that I cannot get Xinerama to work. Every time I turn it on in the options, my machine gets stuck in a neverending boot cycle. If I disable Xinerama, I just have three Xorg screens, but I can't drag windows from one to the other. I can get the 2 lcds on Twinview, and the tv on a separate Xorg screen no problem. But I don't really like this solution. I'd rather have them all on separate screens and stitch them together with Xinerama. Has anyone done this? Here's my xorg.conf for reference. p.s. This took me all of 30 seconds to set up in Windows XP! p.s.s. I've seen somewhere that maybe randr can solve my problems? But I'm not quite sure how?

• How to eliminate overscan on Ubuntu HTPC

  - by Norman Ramsey

  I'm using an Ubuntu box with Nvidia graphics card as an HTPC. My HDTV is a Sony Bravia KDS-R50XBR1; this is a rear-projection unit with many inputs. I am using the HDMI input. I'm using the proprietary Nvidia drivers and they recognize the 1080x1920 resolution just fine. The display is a little fuzzy but at 50 inches it's perfect for movies. My problem is that the TV has three overscan settings, and none of them reduces overscan to zero. When I was using dual-screen this was fine, but I'm moving to where the TV is my only screen, and the Gnome panels are not visible because of the overscan. I'd like to figure out how to eliminate the overscan, without trying to scale my 1080p content down to 920p or something ridiculous like that. Ideally there would be some scurvy trick, perhaps involving the TV service menu, to get rid of the overscan on the TV side. Or I could move the Gnome panels, but I still would be missing the edges of my movies. Suggestions most welcome.
