  • SQL SERVER – SQL Server Performance: Indexing Basics – SQL in Sixty Seconds #006 – Video

    - by pinaldave
    A DBA’s role is critical, because a production environment has to run 24×7, hence maintenance, trouble shooting, and quick resolutions are the need of the hour.  The first baby step into any performance tuning exercise in SQL Server involves creating, analyzing, and maintaining indexes. Though we have learnt indexing concepts from our college days, indexing implementation inside SQL Server can vary.  Understanding this behavior and designing our applications appropriately will make sure the application is performed to its highest potential. Vinod Kumar and myself we often thought about this and realized that practical understanding of the indexes is very important. One can not master every single aspects of the index. However there are some minimum expertise one should gain if performance is one of the concern. More on Indexes: SQL Index SQL Performance I encourage you to submit your ideas for SQL in Sixty Seconds. We will try to accommodate as many as we can. Here is the interview of Vinod Kumar by myself.

  • The Inebriator: A DIY Arduino-powered Cocktail Machine [Video]

    - by Jason Fitzpatrick
    We’ve seen our fair share of geeky alcohol-related projects over the years but this, this, is something to see. The Inebriator is the slickest automated drink machine we’ve laid eyes on. Before we even start talking specs, check out the video above–don’t forget to first assure your liver that you don’t actually have access to such a magnificent device and it can remain calm. As dazzled as we were? The whole thing is powered by an Arduino Mega 2560, sports a cooler with nitrogen pressurization of drink mix bottles, and relies on a rather ingenious and elegantly simple 12v valve system. It even has an RFID security system to prevent party goers with a few drinks in them from messing up the custom drink menu. Hit up the link below for more information, including photos of the guts and technical specs.

  • How Mars Lost Its Atmosphere [Video]

    - by Jason Fitzpatrick
    Scientists have long theorized that Mars once had an atmosphere and surface water–but where did it go? This video showcases one of their theories about Mars’ vanished water reserves. Courtesy of NASA and the NASAexplorer channel: When you take a look at Mars, you probably wouldn’t think that it looks like a nice place to live. It’s dry, it’s dusty, and there’s practically no atmosphere. But some scientists think that Mars may have once looked like a much nicer place to live, with a thicker atmosphere, cloudy skies, and possibly even liquid water flowing over the surface. So how do you go from something like this–to something like this? NASA’s MAVEN spacecraft will give us a clearer idea of how Mars lost its atmosphere, and scientists think that several processes have had an impact.

  • Can Dungeons & Dragons Make You More Successful? [Video]

    - by Jason Fitzpatrick
    Dungeons & Dragons gets a bit of a bad rap in popular culture, but in this video treatise from Idea Channel, they propose that Dungeons & Dragons wires players for success. There are some deeply ingrained stereotypes about Dungeons & Dragons, and those stereotypes usually begin and end with people shouting “NERD!!!” But the reality of the D&D universe is a whole lot more complex. Rather than being an escape from reality, D&D is actually a way to enhance some important real life skillz! It’s a chance to learn problem solving, visualization, interaction, organization, people management… the list could go on and on. Plus, there are some very famous non-nerds who have declared an affinity for D&D, so best stop criticizing and join in if you want to be a successful at the game of life. While we’re trying not to let our love of all things gaming cloud our judgement, we’re finding it difficult to disagree with the premise that open-ended play fosters creative and adaptive thinking.

  • Game: Age of Empires sound good but video "out of range"

    - by Ezekiel
    I'm new to the Ubuntu realm. Currently i'm using Linux Mint 12 with Wine 1.4 and PLAYONLINUX as game loading/playing programs. Video card is MSI GeForce FX5200 (NVIDIA) and is 3d enabled. I can play "Call of Duty 5 demo just fine. My real love is the Age of Empires series games. I loaded the WINE version of AOE 1 demo. No sound and no picture. Black screen with "Out of Range" window in red. I loaded my CD version of AOE 1 through PLAYONLINUX. I get the sound just fine but again the black screen with "Out of Range" window in red. I have used all the monitor settings in both the "settings" and in winecfg. None of the eight monitor options worked in any combination. I have checked all the questions and blogs on this error and tried all I found and no one seems to come up with a real fix. I guess I need to know exactly what the "Out of Range" means. Any help? Anywhere? Thanks

  • Encoding multiple video streams with a single avconv invocation

    - by automatthias
    I played with avconv on Ubuntu and I'm now able to e.g. record the desktop with sound from a soundcard. One thing I wanted to do was recording two video inputs at the same time, for instance the desktop and from the webcam. I thought about doing something like this: avconv \ -f alsa \ -i default \ -acodec flac \ -f video4linux2 \ -r 6 \ -i /dev/video0 \ -f x11grab \ -i :0.0 \ out.mkv My thinking was that if you define multiple video inputs, and the .mkv format can handle multiple video streams, avconv will encode 2 video streams and 1 audio stream into one file. But this isn't what happens: avconv version 0.8.4-6:0.8.4-0ubuntu0.12.10.1, Copyright (c) 2000-2012 the Libav developers built on Nov 6 2012 16:51:11 with gcc 4.7.2 [alsa @ 0x1091bc0] capture with some ALSA plugins, especially dsnoop, may hang.

I'm not sure if it's the question of mapping (some -map options to add?) or that avconv just can't encode more than 1 video stream at one time. So is it an actual avconv limitation, or a limitation of the available containers, or me simply not finding the right combination of command line options?

  • What is the most Linux friendly video card chipset/manufacturer on the market?

    - by rrc7cz
    I've wasted an absurd amount of time trying to get my nVidia card to function properly in Linux (Ubuntu & Fedora). I've decided to purchase a new video card that will "just work" with any Linux I throw at it. Making things even easier, I'm not a gamer, though I do appreciate some of the 3D or alpha blending effects seen in modern GUIs. What cards and/or manufacturers do you recommend for the maximum acceleration with minimum problems?

  • Missing audio and problems playing FLV video converted from 720p .mov file with FFMPEG

    - by undefined
    I have some .mov video files recorded from a JVC GC-FM1 HD video camera in 720p mode. I have FFMPEG running on a Linux box that I upload files to and have them encoded into FLV format. The video appears to be encoding ok but there is no audio in the resulting FLV file and when I play it back in Flash Player in a browser or on Adobe Media Player, the video pauses at the start. It appears that Adobe Media Player waits for the progress bar to reach the end of the video before starting the playback - i.e. the video will load, the picture pauses, the progress bar seeks to the end as if the video was playing then when it reaches the end the video picture starts. There is no audio on the video. I am noticing this in the video player I have built with Flash 8 using an FLVPlayback component and attached seekBar. The seek bar will start moving as if the video is playing but the picture remains paused. Here are some outputs from my FFMPEG log and the command I am using to encode the video - my FFMPEG command called from PHP - $cmd = 'ffmpeg -i ' . $sourcelocation.$filename.".".$fileext . ' -ab 96k -b 700k -ar 44100 -s ' . $target['width'] . 'x' . $target['height'] .

  • Non-flash / No-plugin Video chat?

    - by matty
    We are developing a social website and looking to implement video/audio chat for users (people a user is friends with). Most of the talk from the tech team was to use flash. But I don't want users to install anything. Can video/audio/conferencing be done purely in AJAX? Either develop it from scratch or use open source frameworks if any?

  • Windows Media Based video audio converter?

    - by acidzombie24
    This may seem like an odd question. Right now ONLY windows media player, VLC and media player classic opens and plays my audio video correctly. Virtualdub plays it back with the wrong framerate and losses the audio, Avidemux 2.5 seems to be able to dump the audio/video but the video (like all other apps) is either a bad framerate or is wrong (glitches and bad framerate or bad dump). Nothing recognizes the audio file and when playing the video Avidemux (and most other things) die. FFMPEG cant seem to split the video or audio (using copy -an and etc) and this is getting me very angry. VLC dumps the video incorrectly when i try dumping it with that too. What can i use to convert the video? its streaming so it starts at 26mins in and ends at 28 (this is where apps have the problem. They dont know this and fudge everything or crash). I manage to dump the audio with Avidemux but virtualdub and ffmpeg says unreconized codec. Even if i cant convert it (it seems compressed enough) i want to at least attach it back into an AVI.

  • What is the simplest way to render video into memory (for drawing to a texture) in .NET?

    - by sebf
    In my project I would like to be able to play back video on surfaces in the world. I intend to do this by having the video frames rendered to a block of memory, then use this to update a texture each frame. Everything is in place - except for the part that actually gets the video. I have looked on Google and found that the video library world is very expansive (and geared towards video processing), and am having trouble finding a suitable one. FFMpeg is very comprehensive, but is an entire suite and would take a good amount of work to integrate. So far the most promising library I've found is the one based on the VLC player libraries - by virtue of it using the same resources as VLC Player it is known to be very capable; it also renders to blocks of memory, but the API (at least of the one on Codeplex) is more of a port of the C++ API rather than a managed wrapper. The 'solution' can be any wrapper/API/library, but with characteristics that make it suitable for use in a rendering engine, namely: Renders the video frame data to memory, so it can be picked up and passed to a texture on the GPU easily. Super simple - all that is needed is a way to load, jump and render a frame programatically - ideally it would use the systems codecs and not require an assortment of plugins. Permissive license (LGPL or more free-er) .NET bindings at least; all the better if it is natively managed Can anyone suggest a lightweight, (.NET) library, that can take a video file, and spit out some frames into a byte[]?

  • Unable to watch a high resolution and high frame rate video

    - by Abhijith Madhav
    I have a video of a tennis match whose Resolution = 1280 * 720 Codec = H264 Frame rate = 50fps (Copy paste from info given by totem media player) My laptop is not powerful enough to play this video smoothly. How can I reduce the frame-rate of this video so that my laptop can play it? I have observed that my laptop can play videos with 25fps without an issue. I use ubuntu. I wouldn't mind using windows to edit/re-encode this video.

  • Will iPad 4.0 support video out for Safari?

    - by Greg Mills
    I noticed on the Apple store product comments regarding the iPad video out connector that only specific Apps will provide video out.... I already have a situation where I need to project Safari but only Keynote and a few other Apps support video out.... Does anyone know if the iPad 4.0 operating system will offer full video out as in mirroring?

  • YouTube custom thumbnails feature availability

    - by skat
    I've been trying to figure out this on my own for weeks, but now I give up. 'Custom thumbnails' feature on YouTube is such a controversial one, it was changed so much... so much that even FAQ on YouTube doesn't fully describe it's features (as I see). I have a YouTube channel for one of my websites. This YouTube channel is main marketing force for my website - it brings all the boys to my yard (I mean, website). So I have to use all the hacky-tricky stuff to increase my visibility on youtube. And damn, those custom thumbnails are giving me hard times... As far as I understand, this is current state of 'custom thumbnail' feature: "If your account is in good standing, you may have the ability to upload custom thumbnails for your video uploads." (c) https://support.google.com/youtube/answer/138008 My channel has good standing, has more than 50000 views. So why the hell my account is still not eligible for this feature? anyone have any idea?
