  • How Curiosity Took Its Self Portrait [Video]

    - by Jason Fitzpatrick
    There was enough confusion among the public as to how exactly the Curiosity Rover was able to photograph itself without the camera arm intruding into the photo that NASA released this video detailing the process. For those readers familiar with photograph blending and stitching using multiple photo sources, this should come as no surprise. For the unfamiliar, it’s an interesting look at how dozens of photos can be blended together so effectively that the arm–robotic or otherwise–of the photographer can be taken right out. Hit up the link below to read more about how NASA practiced on Earth for the shot and to see a high-res copy of the actual self portrait.

  • Sound Waves Visualized with a Chladni Plate and Colored Sand [Video]

    - by Jason Fitzpatrick
    This eye catching demonstration combines a Chladni Plate, four piles of colored sand, and a rubber mallet to great effect–watch as the plate vibrates pattern after pattern into the sand. A Chladni Plate, named after physicist Ernst Chladni, is a steel plate that vibrates when rubbed with a rubber ball-style mallet. Different size balls create different frequencies and each frequency creates a different pattern in the sand placed atop the plate. Watch the video above to see how rubber balls, large and small, change the patterns.

  • Recaptcha php problem [closed]

    - by Sam Gabriel
    Hey guys, I'm using recaptcha and I've got a problem, when a user clicks the signup button it redirects him to the sign up verification page, and here is the code, found on the very top of the web code, that checks the recaptcha entered data. <?php require_once('recaptchalib.php'); $privatekey = "***"; $resp = recaptcha_check_answer ($privatekey, $_SERVER["REMOTE_ADDR"], $_POST["recaptcha_challenge_field"], $_POST["recaptcha_response_field"]); if (!$resp->is_valid) { header('location: signup.php'); } ?> But it seems whatever I type in in the recaptcha box, be it right or wrong, I get redirected to the signup.php page. Here is the recaptcha code in the signup.php page: <?php ini_set('display_errors', 'On'); error_reporting(E_ALL | E_STRICT); require_once('recaptchalib.php'); $publickey = "***"; echo recaptcha_get_html($publickey); ?>

  • Computer-controlled Lights and Music Synced into Christmas Rock Spectacular

    - by Jason Fitzpatrick
    This spectacular computer controlled and synchronized lighting display combines thousands of feet of LED lighting, multiple controllers, and a rock medley to great effect. The above display started life as the personal Christmas light display of Sioux Falls, ND resident Joe Noe. When Noe moved, he donated his display to a local mall in order to preserve the tradition of people stopping by to see it and making donations to the Make-A-Wish foundation. The local mall, Western Mall, expanded the display and added in even more LEDs and controllers. The end result is an impressive display synced to a Christmas rock medley by UK musician Richard Campbell.

  • One-line command to download Ubuntu ISO?

    - by James Mitch
    I want to download an Ubuntu ISO, preferably over bittorrent, and verify its integrity. Currently, the following steps are required: start web browser, go to ubuntu.com, find download link find gpg signature for the checksums get the gpg key to check gpg signature of the checksums wait until download finished gpg verifiy checksum verification Isn't there a simpler way? Just like apt-get install 12.04-64bit-ubuntu-iso apt-get install 12.04-32bit-server-iso etc.? Of course, apt-get (or whatever it would be called) should download over bittorrent to remove load from the servers. If it doesn't exist, it should probable post that at ubuntu brainstorm? Is there already such a tool? I wanted to ask before posting to brainstorm.

  • Blog comment spammers &hellip; help!

    - by Steve Clements
    Hey, I need some advice/help, now I’ve been writing on this blog for a few years, I don’t blog a great deal in comparison to many of my peers and my blog doesn’t get a massive number of hits, BUT I seem to get a fair share of comments spammers!! I have an image verification on the comments and I have put an Akismet API key into the Geekswithblogs settings, but I still get a bunch of spam comments. They could almost be real, until you see the link going off to some dating site or casino crap. What does everyone do?? Delete them every time?? Moderate comments?? I would rather not moderate comments if possible, but is that the only way to stop the crap?? Thx Technorati Tags: spammers,comments,help

  • IPSec Offload support in 82576GB controller for Linux

    - by Rodrigo Leal
    Due to migration of servers to cloud computing, we bought several NICs that support mechanisms like SRIOV and VMDQ. Furthermore, as security risk was also a concern and we did not want to create more overhead on the processor, IPSec Offload support was essential. The model chosen was: Intel Gigabit ET2 Quad Port Svr Adptr. (With 82576GB controller): http://ark.intel.com/products/49187/intel-gigabit-et2-quad-port-server-adapter However, we were unable to configure IPSec Offload on Linux. We tried to test on another server we have, a Windows Server 2012 R2, but again without success. It seems that the driver for this controller is not available for windows server 2012 R2, and Linux. The test on windows would be only for verification purposes, we will not use this platform. Could someone confirm this lack of support for Linux?

  • Maximum file size for iFrame in IE7

    - by Peter Turner
    I've got a "super secure" javascript downloader* that I wrote, and it usually works alright. But I noticed, while trying to download a 90 meg file with it on a client's machine that on IE7, it's getting hung up about 1/3rd of the way through. I've never tried to send a file that large through the iFrame and it works fine in other browsers. Is there a size restriction on files that IE7 can read in an iFrame? * It's really just a PHP line that sets header("location: http://someplace/downloadbigthing.exe"); after it does some logging and verification.

  • Connectify Dispatch: Link All Your Network Connections into a Super Pipeline

    - by Jason Fitzpatrick
    Connectify Dispatch is a network management tool that takes all the connections around you–Ethernet, Wi-Fi nodes, even 3G/4G cellular connections–and combines them into one giant data pipeline. At its most simple, Connectify Dispatch takes all the network inputs available to your computer (be those connections hard-line Ethernet, Wi-Fi nodes, or cellular connections) and merges the separate data connections seamlessly into one master connection. If any of the connections should falter (like your 3G reception goes out), Connectify automatically shifts the data to other available networks without any interruption. In addition you can specify which network Connectify should favor with connection prioritization; perfect for using your cellular connection without breaking through your data cap for the month right away. Hit up the link below to read more about Connectify Dispatch and the companion app Connectify Hotspot.

  • Are there any formalized/mathematical theories of software testing?

    - by Erik Allik
    Googling "software testing theory" only seems to give theories in the soft sense of the word; I have not been able to find anything that would classify as a theory in the mathematical, information theoretical or some other scientific field's sense. What I'm looking for is something that formalizes what testing is, the notions used, what a test case is, the feasibility of testing something, the practicality of testing something, the extent to which something should be tested, formal definition/explanation of code coverage, etc. UPDATE: Also, I'm not sure, intuitively, about the connection between formal verification and what I asked, but there's clearly some sort of connection.

  • How to Access Your Router If You Forget the Password

    - by Chris Hoffman
    Routers protect their web interfaces, where you can configure their networking, parental control, and port forwarding settings, with a username and password. These default passwords can be changed to protect the router’s settings. If you’ve forgotten a router’s password – or if you acquired a used router and don’t know its password – there’s a way to reset the password. You may also be able to forward ports without knowing the password.

  • Get Real Multitasking on Android With These 8 Floating Apps

    - by Chris Hoffman
    Android has decent multitasking, but the missing piece of the puzzle is the ability to have multiple apps on-screen at the same time – particularly useful on a larger tablet. Floating apps fill this need. Floating apps function as always-on-top windows, allowing you to watch videos, browse the web, take notes, or do other things while using another app. They demonstrate how Android’s interface is more flexible than iOS and the Modern UI in Windows.

  • Is an 'if password == XXXXXXX' enough for minimum security?

    - by Morgan Herlocker
    If I create a login for an app that has middle to low security risk (in other words, its not a banking app or anything), is it acceptable for me to verify a password entered by the user by just saying something like: if(enteredPassword == verifiedPassword) SendToRestrictedArea(); else DisplayPasswordUnknownMessage(); It seems to easy to be effective, but I certainly would not mind if that was all that was required. Is a simple check on username/password combo enough? Update: The particular project happens to be a web service, the verification is entirely server side, and it is not open-source. Does the domain change how you would deal with this?

  • Custom Silent HTPC Uses Entire Case as a Heatsink

    - by Jason Fitzpatrick
    This silent media center PC dissipates heat in a rather clever way; the entire back of the case is one giant heatsink. Courtesy of computer enthusiast and tinker DeFex, the build isn’t just silent but quite eye catching too. He used a combination of one massive heatsink, custom brackets, acrylic, and bicycle spokes to create a sleek case that looks as much like a computer-inspired work of art as it does a media center computer. Hit up the link below to check out the build gallery and see how he mated the CPU to the heatsink-body with a custom milled aluminum bridge.

  • What are the processes of true Quality assurance?

    - by user970696
    Having read that Quality Assurance (QA) is focused on processes (while Quality Control (QC) is focused on the product), the books often mentions QA is the verification process - doing peer reviews, inspections etc. I still tend to think these are also QC as they check intermediate products. Elsewhere I have read that QA activity is e.g. choosing the right bugtracker. That sounds better to me in terms of process improvement. The question that close-voting person obviously missed is pretty clear: What are the activities that true QA should perform? I would appreciate the reference as I work on my thesis dealing with all these discrepancies and inconsistencies in the software quality world.

  • Is it possible to remove a particular host key from SSH's known_hosts file?

I opened the known_hosts file, and other han understanding that the file contains fingerprints for a given machine, I dont understand anything. Below is the message I faced, which led me to ask this question. Add correct host key in /home/wissen16/.ssh/known_hosts to get rid of this message. Offending key in /home/wissen16/.ssh/known_hosts:1 RSA host key for foo.com has changed and you have requested strict checking. Host key verification failed. Thanks.

  • Using another domain with Google App Engine

    - by gsingh2011
    I'm trying to change my google app engine domain (domain.appspot.com) to the domain I bought from 1&1.com (mydomain.com). I went into the google app engine settings and added the domain. After making a Google Apps account, I was asked to verify my domain. The directions say that 1&1 doesn't allow me to create TXT records, so I can't use that method for verification. Their alternative is to upload an HTML file to my server, but I didn't buy hosting with my domain, I just bought the domain. My files are on domain.appspot.com. How can I make mydomain.com point to domain.appspot.com? I've added the ns1.googleghs.com as my nameservers in my 1&1 DNS settings, but I still can't verify my domain with Google Apps.
