  • How to flip video feed that's presented upside down?

    - by Zuul
    Skype an other applications running under windows 7 Ultimate are presenting the video captured from the laptop built-in webcam upside down. I've tried many solution that I was able to find regarding issues like this, but to no avail. Some of the most relevant are discussed here: From Skype Support Network, the thread why is my video image of myself upside-down??? From ASUSTek Forums, the thread Built-in camera upside down Both present several potential solutions to this issue, but I've been unable to fix it for the laptop ASUS U6S. What I've already tried: Changing Drivers The driver that works must be the one from Windows, all others available from ASUS drivers either don't install or install but the webcam doesn't provide any video feed. This disallows all options that concern using an older driver or editing the .inf file as to manually adjust the settings. ASUS does not provide drivers for Windows 7, so I've used drivers from Windows Vista 32 Bit. Using the application manycam This application actually solves the issue (temporarily), but creates new ones: If I use the application to flip the video feed, Skype video call cease to work. This application doesn't save the settings, at least I wasn't able to find any way to save the settings I've used to flip the video feed. A computer restart brings all back to how it was, video feed upside down and if the application is still installed, Skype continues to fail on video calls. Regedit I've searched thru Windows Registry Editor as to find any reference to the webcam settings, hopping to find a key with the Flip parameter, since it's up to the driver to flip the image (by what I could ascertain from this problem). Couldn't find any reference to such settings, either they actually don't exist within the Windows Registry or they use some weird name that I could think off. System Configuration I was able to access the webcam system settings from the Windows Device Manager, but the tab that actually has the Image Rotation setting is always disabled. The same goes for the settings available from the Skype webcam options (that essentially is presenting the same settings as Windows Device Manager, just within a custom Skype pop-up). Question: How can I flip the video feed from the laptop's built-in webcam, as to properly see and broadcast the video?

  • Mouse pointer size inconsistent

    - by charon00
    Since installing Ubuntu 12.04, I've been having a problem with the mouse pointer size. On the desktop, it is quite a bit larger than it should be (24), though the different cursors (editing text, hyperlink hand, etc) are correct. The size changes to the correct size when the pointer is over some application windows (GVim, Netbeans, Firefox), but then changes back once it is moved out of the window. There was a similar question here, but the Xdefaults solution did not work for me, and I didn't want to try the one requiring editing the icon image. In addition, I've tried changing the cursor theme using sudo update-alternatives --config x-cursor-theme as well as using the dconf-editor, but though I can change the theme, the size issue remains. In case it's relevant, I'm running on a dual-screen setup with monitor sizes of 2560x1600 and 1920x1080, using the NVidia video driver. Is there another way to control pointer size, or a setting that might be messing it up? EDIT: These are the values/options I have for update-alternatives and in dconf-editor. I'm now wondering if Netbeans and Firefox are making the mouse pointer smaller than it should be, but I'm not sure how big 24 should be... update-alternatives: Selection Path Priority Status ------------------------------------------------------------ 0 /usr/share/icons/DMZ-White/cursor.theme 90 auto mode 1 /etc/X11/cursors/core.theme 30 manual mode 2 /etc/X11/cursors/handhelds.theme 20 manual mode 3 /etc/X11/cursors/redglass.theme 20 manual mode 4 /etc/X11/cursors/whiteglass.theme 20 manual mode * 5 /usr/share/icons/DMZ-Black/cursor.theme 30 manual mode 6 /usr/share/icons/DMZ-White/cursor.theme 90 manual mode dconf-editor: I can't post the image since I'm a new user but the cursor-size is set to 24 and the cursor-theme is DMZ-Black.

  • 16-bit PNGs in Slick2D

    - by Neglected
    I'm working on a project and I'm using some 3rd party sprites just to get it off the ground; recently I've come into a hitch. Slick2D doesn't seem to want to load my images. That is, it will warn me that images are the wrong bit-depth. All the images are in 16-bit PNG form (PNG is required for transparency). Is there any way I can disable the warning (being the bad guy programmer (the console print for each individual load REALLY SLOWS DOWN the image)) or is there another solution? I was thinking about converting all images (using imagemagick) to .gif (with an alpha channel). Would there be any loss in quality between formats? EDIT: I tried using imagemagick but some of the sprites use pure black so I can't do that without wrecking the image. EDIT2: using "identify" on any of the images show them as being 8-bit.. but Slick2D won't load them. What the hell? D: EDIT3: Issue solved (ish). If you are googling this then just disable the java png loader from slick by sticking this somewhere in your code (like the main method): System.setProperty("org.newdawn.slick.pngloader", "false");

  • Laser range finder, what language to use? Beginner advice

    - by DrOnline
    I hope this is the right place. I am a programming beginner, and I want to make a laser range finder, and I need advice about how to proceed etc. In a few weeks I will get a lot of dirt cheap 3-5V lasers and some cheap usb webcams. I will point the laser and webcam in parallel, and somehow use trigonometry and programming to determined distance. I have seen online that others made done it this way, I have purposefully not looked at the details too much because I want to develop it on my own, and learn, but I know the general outline. I have a general idea of how to proceed. The program loads in a picture from the webcam, and I dunno how images work really, but I imagine there is a format that is basically an array of RGB values.. is this right? I will load in the red values, and find the most red one. I know the height difference between the laser and the cam. I know the center dot in the image, I know the redmost dot. I'm sure there's some way to figure out some range there. TO THE POINT: 1) Is my reasoning sound thus far, especially in terms of image analysis? I don't need complete solutions, just general points 2) What I need to figure out, is what platform to use. I have an arduino... apparently, I've read it's too weak to process images. Read that online. I know some C I know some Python I have Matlab. Which is the best option? I do not need high sampling rates, I have not decided on whether it should be automated or whether I should make a GUI with a button to press for samples. I will keep it simple and expand I think. I also do not need it to be super accurate, I'm just having fun here. Advice!

  • Have I created the recovery disk from recovery partition correctly?

    - by Tim
    I was creating recovery disk from recovery partition on my Lenovo T400 with Windows 7. 6.5 GB of the recovery partition has been occupied. But in the process, I created three DVDs. I might remember wrong, but the first two DVDs were called by the wizard as disk 1, and the third one was called disk 2. The first one has been written 0.22 GB only. Following is the content of the DVD (right click the image and select view the image in a bigger size): The second one has been written 3.97 GB as follows: The third one has been written 2.44 GB as follows: I am allowed only one time to create recovery disk. So I cannot try again. So I was wondering if I missed something? How is the creation process supposed to be like? Thanks and regards!

  • Boot Linux from DOS (with loadlin.exe etc)

    - by dreamlax
    I have been using the latest version of loadlin.exe (version 1.6e). It works on some machines but on others I get "no place after kernel for initrd". The kernel is about 5MB in size (non-modular) and my initrd image (decompressed) is about 8MB. One route that I could take is to enable module support and offload some of the weight of the kernel into the initrd image but I'm not confident this will rectify the issue. Are there any alternatives to loadlin.exe that are capable of loading Linux from a booted DOS session? I basically have a series of DOS tools that I'd like to run one after another and then boot into Linux, which loadlin.exe seems to be working very well for except on some machines.

  • No text in working indicator-messages after enabling different icons depending on the status

    - by user106750
    My indicator-messages has some problems. As you can see in the image, there appears no text. The indicator is working correctly, if there is some income, a number will appear in its proper place or I will be able to see the minutes passed after I got an email, but still no information. As you can see in the picture, I changed the envelope icon for the status one. I configured it as is indicated in http://www.omgubuntu.co.uk/2012/08/ubuntu-add-new-message-indicator-icons, with the indicator changing depending on the status. But I modified it so I see the bubble. The bubble gets the arrow when I'm absent, for example, or an "X" of I'm disconnected, and also turns blue if there an income. I believe the problem is related with this new indicator. The first days, it was working fine, but then the text dissapeared. I've tried uninstalling and reinstalling the packet, with no success. I'm using ubuntu 12.10 64bits with Unity. Someone has an idea how to fix this? I would prefer conserving the characteristic of having different icons. Thanks a lot!!!

  • Hyperlinks on images in PDF from Word 2010

    - by Bristol
    I've got a Word 2010 document that I'm trying to convert to a PDF with "Save As...", preserving hyperlinks. Something odd is going on: Hyperlinks on inline text, or images that are inline, work fine. Hyperlinks on images with layout "in front of" text don't work in the PDF, same for hyperlinked drawing shapes. What I'm trying to do is make a "clickmap" image by putting an image on the page and overlaying parts of it with transparent shapes that hyperlink to different URLs. This isn't working, and the transparency has nothing to do with it - hyperlinks in the PDF seem only to work on "in line with text" elements. Am I missing something, or is there a better way to do this?

  • Why does 'dd' not work for creating bootable USB?

    - by jdowner
    Recently I wanted to create a bootable USB of Linux mint. I found that there was a lot of conflicting advice/experience about whether the 'dd' command could be used to create a bootable USB. I decided to download an ISO and try. While dd definitely put the image on the USB stick it was not bootable. So my question is what is the magic ingredient that will make this work or why has this approach persisted if it does not work? This is the command I used, dd if=/mint/iso/image of=/dev/sdb1 oflag=direct

  • ExplorerCanvas and JQuery

    - by PhubarBaz
    I am working on a Javascript app (CloudGraph) that uses HTML5 canvas and JQuery. I'm using ExplorerCanvas to support canvas in IE. I recently came across an interesting problem. What I was trying to do is restore the user's settings when the page is loaded. I read some information from a cookie that I set the last time the user accessed the application. One of these settings is the size of the canvas. I decided that the best place to do this would be when the document is ready using JQuery $(document).ready(). This worked fine in browsers that natively support the canvas element. But in IE it kept getting errors the first time I would hit the page. It seemed that the excanvas element wasn't initialized yet because I was getting null reference and unknown properties errors. If I refreshed the page the errors went away but the resized canvas wasn't drawing on the entire area of the canvas. It was like the clipping rectangle was still set to the default canvas size. I found that the canvas element when using excanvas has a div child element which is where the actual drawing takes place. When I changed the width and height of the canvas element in document.ready it didn't change the width and height of the child div. Initially my solution was to also change the div element when changing the canvas element and that worked. But then I realized that having to refresh the page every time I started the app in IE really sucked. That wouldn't be acceptable for users. Since it seemed like the canvas wasn't getting initialized before I was trying to use it I decided to try to initialize my app at a different time. I figured the next best place was in the onload event. Sure enough, moving my initialization to onload fixed all of the problems. So, it looks like the canvas shouldn't be manipulated until the onload event when using ExplorerCanvas. There might be ways to do it when the document is ready. I found some posts on initializing excanvas manually, but for me waiting until onload worked just fine.

  • Use Amazon EC2 as a backup server

    - by MikeMurko
    I would like to use Amazon EC2 as an emergency backup database+web server in the event our primary host becomes unavailable. I feel like I wouldn't have trouble setting up a Windows instance, install SQL Server and get the web server up and running (would take a few hours, plus installing various libraries, our source code, etc). My question relates to pricing. If I simply "stop" the instance rather than "terminate" it, does that stop counting "instance-hours"? I would prefer not to terminate the instance and lose all that work I spent setting it up. If I must "terminate" in order to stop the billing - is it possible to make an image of the server after I have set it all up, then save that image somewhere (S3?) Is this something that people do regularly? Ideally this instance would just be waiting in the wings for an issue with our host, but costing us nothing except perhaps data storage costs.

  • Solaris 11 VNC Server is "blurry" or "smeared"

    - by user12620111
    I've been annoyed by quality of the image that is displayed by my VNC viewer when I visit a Solaris 11 VNC server. How should I describe the image? Blurry? Grainy? Smeared? Low resolution? Compressed? Badly encoded? This is what I have gotten used to seeing on Solaris 11: This is not a problem for me when I view Solaris 10 VNC servers. I've finally taken the time to investigate, and the solution is simple. On the VNC client, don't allow "Tight" encoding. My VNC Viewer will negotiate to Tight encoding if it is available. When negotiating with the Solaris 10 VNC server, Tight is not a supported option, so the Solaris 10 server and my client will agree on ZRLE.  Now that I have disabled Tight encoding on my VNC client, the Solaris 11 VNC Servers looks much better: How should I describe the display when my VNC client is forced to negotiate to ZRLE encoding with the Solaris 11 VNC Server? Crisp? Clear? Higher resolution? Using a lossless compression algorithm? When I'm on a low bandwidth connection, I may re-enable Tight compression on my laptop. In the mean time, the ZRLE compression is sufficient for a coast-to-coast desktop, through the corporate firewall, encoded with VPN, through my ISP and onto my laptop. YMMV.

  • News Applications internal working [on hold]

    - by Vijay
    How does news applications work other than RSS Feed based applications? I know some of them take the RSS content from the source site.But sometimes I see, those applications show - Title Description Date Image video etc. Even though when I see the original site's rss, image, video is not there in rss. So how does one get that to show in there applications? Some applications even shows feeds from magazine sites, newspaper sites. How do these applications work? I am creating an application which will link to different news sites feeds categorized (like top news, technology, games, articles etc.) On the front page it will show the website names, then on selection of any news site it will get the feed from that website and show it to user. So I would like to know All the fetching of data from should be done on user selection or data should be prefetched? Detailed information I want to fetch from the original like provided in the rss data. How should I go about it?

  • Blurred refurbished TFT

    - by PeterMmm
    I got 3 refurbished PC+TFT 19". All TFT shows a very blurry image. I estimate the TFT's are 2-3 yrs old. The PC's running Windows7 Pro. The resolution is set to the TFT native values. It could be possible that all TFT's are broken but I have similiar models that are up to 5 yrs old, without any issue. I still think it could be a config issue but from the hardware it is possible that a TFT get broken I shows up a very blurry image. Update TFT HP 2035, grafic Intel Q35/GMA 3100, analog D-SUB connector, Manuf. date Sep 2005. Config. resolution 1600x1200, PPP 150% Without ClearType it is worst. Desktop Icon titles seems to be good and clear. But in Notepad for example the effect is that on the right of the characters is a pinky shadow.

  • How do I move an Amazon micro instance to a small instance?

    - by Navetz
    I want to move my instance to a micro instance to a small instance but when I try to launch a new AMI based on my Micro instance AMI it only gives me the option for 64 bit instances. My initial ami is based off an ubuntu 10.04 image. Is it not possible to move between 64 bit and 32 bit instance? Would it be possible to use a load balancer to have a 32bit instance and a 64bit instance work together? I have a website/web app that I will be uploading huge volumes of data to. I will be starting with 65gigs of images and then moving up to 100+ gigs of images. I am not sure which instance type would be best for this. I was going to use a load balancer and auto scaling to increase the number of instance when the load is high. Also when using a load balancer, does one of the AMI instance become the primary image and the rest act as clones of it?

  • Algorithm to zoom a plotted function

    - by astinx
    I'm making a game in android and I need plot a function, my algorithm is this: @Override protected void onDraw(Canvas canvas) { float e = 0.5f; //from -x axis to +x evaluate f(x) for (float x = -z(canvas.getWidth()); x < z(canvas.getWidth()); x+=e) { float x1,y1; x1 = x; y1 = f(x); canvas.drawPoint((canvas.getWidth()/2)+x1, (canvas.getHeight()/2)-y1, paintWhite); } super.onDraw(canvas); } This is how it works. If my function is, for example f(x)=x^2, then z(x) is sqrt(x). I evaluate each point between -z(x) to z(x) and then I draw them. As you can see I use the half of the size of the screen to put the function in the middle of the screen. The problem isn't that the code isn't working, actually plots the function. But if the screen is of 320*480 then this function will be really tiny like in the image below. My question is: how can I change this algorithm to scale the function?. BTW what I'm really wanting to do is trace a route to later display an animated sprite, so actually scale this image doesnt gonna help me. I need change the algorithm in order to draw the same interval but in a larger space. Any tip helps, thanks! Current working result Desired result UPDATE: I will try explain more in detail what the problem is. Given this interval [-15...15] (-z(x) to z(x)) I need divide this points in a bigger interval [-320...320] (-x to x). For example, when you use some plotting software like this one. Although the div where is contain the function has 640 px of width, you dont see that the interval is from -320 to 320, you see that the interval is from -6 to 6. How can I achieve this?

  • Open application in background without losing current window focus. Fedora 17, Gnome 3

    - by Ishan
    I'm running a script in the background which loads an image with feh depending on which application is currently in focus. However, whenever the script opens the image, window focus is lost to feh. I was able to circumvent this by using xdotool to switch back to the application that was originally in focus, but this introduces a short annoying period of time where the focus is switched from feh to the application. My question is this: is there any way to launch feh in the background such that window focus is NOT lost? System: Fedora 17, Gnome 3, Bash Thanks a ton!

  • Can Windows Home Server be used on an active directory domain?

    - by Parvenu74
    The situation: an Active Directory network with a few dozen machines. Most of the machines have the same vanilla image applied to them so if there was a hard drive failure getting the machine back up to the standard network image would be quick and easy. However, there are a handful of (eight) machines which have rather unique setups (accounting, developers, the "artist" with CS4 and such). For these machines we would like to use Windows Home Server since the backups are automatic and recovery from a machine failure is quite painless. The question though is whether or not WHS can be used on an A/D network. If not, what "set it and forget it" backup/imaging product is recommended for this scenario?

  • virtual machines: optimal host os to run Windows XP guest os?

    - by user61132
    My department doesn't have the budget to upgrade my ailing Dell D620 laptop. However, I do have the option to buy my own personal computer, then use my company-issued ISO image to run Windows XP as my guest os using virtualbox or vmware. Therefore, last month, I bought an Acer AX3910-U3012 desktop that had Windows 7 as the host os (and 8G RAM). In short, I was disappointed with the performance while trying to run WinXP as the guest os. (It didn't perform much better than my laptop.) Just wondering what the optimal host os would be for running Windows XP as the guest os? (No, I can't use my company-issued ISO image to build the os for my personal computer.) FWIW, I'm willing to spend up to $2k if it's REALLY worth it, but would prefer to spend no more than $1k. Also, in an effort to cut costs, I'd prefer buy a desktop instead of a laptop. Thanks for any/all feedback.

  • Utility to take daily screenshots of a webpage

    - by Kevin L.
    I would like to have a visual history of my Tomato bandwidth graphs, so that I can roughly/manually correlate them with some other factors. Tomato can squirrel away the actual data points, but I'd rather not deal with importing it into some visualization tool. For sheer simplicity, a single image per day would be preferable. I'd like a program that can wake up at say, midnight, take a screenshot of a given webpage (the URL will always be the same), and save that image to a folder, maybe named after the date/time. I'd prefer OS X, but Windows and Linux are fair game too; I use all three. Any suggestions?

  • I would like to burn a file to a virtual dvd.

    Hi, a program I am using tracks down my diskdrives and offers to write a dvd image to them. I would like to be able to write this image on HD in stead of on disk, but I have no option to browse the file system. Therefore I would like a virtual dvd disk, that is in fact a folder, but that is recognized by the app. as a real, empty dvd. I have tried MagicDisk, but it doesn't seem to offer the ability to couple an emulated disk drive to a folder...

  • Why do I see different TCP behaviour between IIS and FTP server applications on Windows 2003?

    - by rupello
    I am comparing Wireshark traces of a 10MB file download file from: the FileZilla FTP server and IIS (using HTTP) on the same Windows 2003 server. The FTP download performs faster and the trace shows the server behaving as expected, sending more data to the client with every ACK received: Link to full-size image The HTTP server trace shows a more bursty pattern. The timing of the send bursts are sometimes unrelated to any ACKs received from the client (circled in red): Link to full-size image Anyone have a suggestion as to why IIS traffic is having like this? Update: We have tried modifying the http.sys registry settings (setting MaxBytesPerSend to 256k and MaxBufferedSendBytes to 64k as recommended). Changing MaxBytesPerSend does seem to improve performance by increasing the amount of in-flight data , but we still see the same bursty pattern.
