  • Did Blowing Into Nintendo Cartridges Really Help?

    - by Jason Fitzpatrick
    Anyone old enough to remember playing cartridge-based games like those that came with the Nintendo Entertainment System or its successors certainly remembers how blowing across the cartridge opening always seemed to help a stubborn game load–but did blowing on them really help? Mental Floss shares the results of their fact finding mission, a mission that included researching the connection mechanism in the NES, talking to Frank Viturello (who conducted an informal study on the effects of moisture on cartridge connectors), and otherwise delving into the history of the phenomenon. The most interesting part of the analysis, by far, is their explanation of how blowing on the cartridge didn’t do anything but the ritual of removing the cartridge to blow on it did. Hit up the link below for the full story. Did Blowing into Nintendo Cartridges Really Help?

  • HDMI audio output problems with Radeon card

    - by Matt Robinson
    No matter how much advice I follow, I still cannot get any audio to come out through my HDMI connection. I've tried downloading the latest proprietary FGLRX graphics drivers, and I've also gone into /etc/default/grub and altered GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" into this GRUB_CMDLINE_LINUX_DEFAULT="quiet splash radeon.audio=1" But still I cannot get any sound nor can I get HDMI sound output to show up in Sound Settings or Pulse Audio Volume Control. I can get video to show up just fine on my monitor through HDMI so I'm sure this problem is fixable! I know this is an old problem with Ubuntu, but any new strategies into the problem would be much appreciated. With that being said, here are some of my specs: Ubuntu 12.04 LTS AMD Radeon HD 7520G

  • HTG Explains: What is the Windows Page File and Should You Disable It?

    - by Chris Hoffman
    Windows uses a page file to store data that can’t be held by your computer’s random-access memory when it fills up. While you can tweak the page file settings, Windows can manage the page file fine on its own. The Windows page file is somewhat misunderstood. People see it as the cause of slowdowns because it’s slower to use the page file than your computer’s RAM, but having a page file is better than not having one.

  • Reproducing a Conversion Deadlock

    Even if two processes compete on only one resource, they still can embrace in a deadlock. The following scripts reproduce such a scenario. In one tab, run this: CREATE TABLE dbo.Test ( i INT ) ; GO INSERT INTO dbo.Test ( i ) VALUES ( 1 ) ; GO SET TRANSACTION ISOLATION LEVEL SERIALIZABLE ; BEGIN TRAN SELECT i FROM dbo.Test ; --UPDATE dbo.Test SET i=2 ; After this script has completed, we have an outstanding transaction holding a shared lock.

  • Atheros 9250 wireless card keeps on disconnecting

    - by Vizi Balázs
    So I bought a Lenovo G575 laptop for learning purposes and found that the connection just simply disconnects if i'ts in use for downloading and it also does disconnect in every 2-5 minutes while browsing.I tested the card with Win7, it worked nicely.Since then I searched through all the topics connected to this card, also tried using older distros, Maverick ended up with the same results as the actual 12.04 distribution.I dont think it's the router cause i could access it from Win7.It's causing me a trouble using an external usb, cause it's taken from another PC in the house.I would be really grateful if someone could explain what should i do to fix it. Thanks in advance for the help

  • Mi-Fi LEGO Contest Showcases Ultra Minimal Sci-Fi Designs

    - by Jason Fitzpatrick
    Many LEGO creations showcased by geeks across the web involve thousands upon thousands of bricks to create perfectly scaled recreations of buildings, movie scenes, and more. In this case, the goal is to recreate an iconic Sci-Fi scene with as few bricks as possible. Courtesy of the LEGO enthusiast site The Living Brick, the Microscale Sci-Fi LEGO Contest or Mi-Fi for short, combines Sci-Fi with tiny, tiny, recreations of scenes from shows and movies in the genre. Hit up the group’s Flickr pool for the contest to check out all the great submissions–including a tiny Star Gate, a mini Star Destroyer, and a surprisingly detailed scene from Planet of the Apes.

  • Web framework able to handle many concurrent users [closed]

    - by Jonas
    Social networking sites needs to handle many concurrent users e.g. for chat functionality. What web frameworks scales well and are able to handle more than 10.000 concurrent users connected with Comet or WebSockets. The server is a Linux VPS with limited memory, e.g. 1GB-8GB. I have been looking for some Java frameworks but they consume much memory per connection. So I'm looking for other alternatives too. Are there any good frameworks that are able to handle more than 10.000 concurrent users with limited memory resources?

  • Problem upgrading from 13.04 to 13.10

    - by Charles
    Part way through upgrading from 13.04 to 13.10 the process ground to a halt with an error message. Now on retrying by going to 'Check for updates' I get the following: Failed to load the package list This is a serious problem. Try again later. If this problem appears again, please report an error to the developers. E:Encountered a section with no Package: header, E:Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_saucy_universe_i18n_Translation-en%%5fGB, E:The package lists or status file could not be parsed or opened. Problem reported but my question is, "what can I do now?; Do I have to do a fresh install?; if so will settings etc. in my Home folder (on its own partition) be saved?" 13.04 still seems to be working perfectly, while upgrading I had a terrible internet connection varying between 'dead slow' and 'dead stop', not sure if that caused the problem.

  • Do programmers possess the means of production?

    - by Peter Turner
    I was listening to The Servile State by Hilare Belloc this morning and pondering whether or not I possessed the means of production, as did the peasant of the middle ages; as did not his descendants after the oligarchs of England forced him into servility. The means of production was the arable land that the serf was seated on, which even though not legally his, was illegal to evict him from. So, as programmers, with the hither-to-unknown supply of free tools and resources, have we reclaimed as a class of workers, unlike any others, the means of production. Given the chance, a midrange PC and a stable internet connection, could we not each of us be wholly self sufficient and not just wage earners?

  • Download mirrors down after fresh installation

    - by user169866
    I dont know whats the problem but it seems after every fresh installation of ubuntu in any device (have started noticing this problem since ubuntu 11.04) the connection to the software sources are down. I cannot download any software from either apt-get or software center. Also i cannot use the Universal Source for packages like chromium, etc. And then suddenly after a few days, the mirrors are back up again!! Its normal back again! I dont know what the problem is, but it happens every time. Is there any solution to this or we just have to wait for a few days till the mirrors are back again? (and I have also tried changing the download server, It doesn't helps!)

  • Warning about SSL ceritificate, am I under attack ?

    - by Bunny Rabbit
    Lately I've been getting a lot of warnings about SSL certifications on my pc, Empathy keeps telling me that Facebook's certificate is self-signed and can't be trusted, and also, there are occasional warnings in Google-Chrome about security. I remember the last one saying that that the page is secured but some of the resources that the page is using are not from a secure connection, something like that. Is my pc hacked / under attack? How can I check that, and if so, how can I safeguard myself? PS: One thing that comes to my mind is that I might be under an arp poisoning / spoofing attack.

  • Broadcom BCM4313 wireless slow and high-latency

    - by Florin Andrei
    Ubuntu 12.10 64 bit on a Dell Latitude E6330 laptop. Wireless is pretty slow. It gets connected quick enough, but then it acts like a dialup connection. My ssh sessions over WiFi are slow and laggy. Even browsing is slow, the pages are loading like it's 1998. This does not depend on the access point, it's the same both at home and at work. Other systems work fine on these access points. I had an older Dell laptop before, different WiFi hardware, and it was much faster over the same wireless access points. Is this a known issue with this hardware? If so, any solutions?

  • Hybrid wireless network repeating

    - by Oli
    Summary: I'd like to use two Ubuntu computers to extend/compliment an existing wireless access point. I have a network which currently looks a bit like this: What the diagram doesn't show is the interference caused by our house. It's a wifi-blocking robot sent here from the past. The two wired computers are in areas where the signal is most blocked (not by design, just a happy co-incidence). Both wired computers have fairly good network cards. They're both Ubuntu machines and I would like to turn them into additional base stations. I know I could throw more networking hardware at this (network extenders or cable in additional, pure wireless access points) but I've got two Linux machines sitting in ideal places and I feel like they should be able to help me out. I've tried ad-hoc networks but I need something that is a lot more transparent (eg you can migrate from base to base without a connection dropping); it should look like one network to clients.

  • Avoid apt-get update while installing softwares on ubuntu, possible?

    - by Rohan
    I want to install a 27KB lens( reddit-lens: here ) & this "apt-get update" is going to download 20MBs(!) of data for the same. I want to avoid this update bcoz i am on a limited bandwidth connection. I also tried to install .deb file(27KB) for this lens but it says "dependancy is not satisfiable gir1.2-unity-3.0". I went on to http://www.pkgs.org to get that package & there is no version available for ubuntu 12.04. What should I do? Can i install softwares without updating cache? Is that update necessary? Also installation of some softwares requires updating cache while others dont, why?

  • Getting Ethernet driver to crippled machine

    - by Richard
    The reply at How do I install drivers for the Atheros AR8161 Ethernet controller? probably helps me. I have a Toshiba S855, bought yesterday. lspci -vv | grep Atheros command from the terminal shows me I have the AR8161 Gigabit Ethernet controller (rev 10) However the answer sudo apt-get install ... requires an internet connection. How can I, using another machine, capture the necessary information on that other machine to copy across to the crippled machine, and then how do I build from there. Thanks in anticipation

  • Uploading a file automatically for speed test?

    - by Abhi
    I am building a Web UI for a device for internet connection and one of the requirements in it is a speed test. I know the basic concept of how speed test works. A file is downloaded for a limited time then the same file is uploaded again and the speed is tracked at regular intervals. Downloading the file is not an issue, but how am I supposed to upload the file without the client knowing that the file is getting uploaded? I've read through a lot of documentation, but I'm still not able to get the answer to how I will upload the file from clients machine without asking him to select the file.

    If you ever want to sign into two different accounts on the same website at once – say, to have multiple Gmail inboxes open next to each other – you can’t just open a new tab or browser window. Websites store your login state in browser-specific cookies. There are a number of ways you can get another browser window with its own cookies and stay logged into multiple accounts at once.

  • How to transform gameObjects in array?

    - by user1764781
    I have an array of available gameObjects in the scene. An array of GO should be transformed according to received floats through UDP connection. I know it is simple, but can't figure it out how to accomplish the transformation an array of GO according to received unique floats for each GO, any help will be appreciated. Here is a transformation floats, it might be helpful I guess: x =ReadSingleBigEndian(data, signalOffset); signalOffset+=4; y= ReadSingleBigEndian(data, signalOffset); signalOffset+=4; z= ReadSingleBigEndian(data, signalOffset); signalOffset+=4; alpha= ReadSingleBigEndian(data, signalOffset); signalOffset+=4; theta= ReadSingleBigEndian(data,signalOffset); signalOffset+=4; phi= ReadSingleBigEndian(data,signalOffset); signalOffset+=4;
