  • Getting error-'General Error Mounting Filesystems' while installing ubuntu 12.04 alongside Windows 7 starter edition

    - by Yashendra Shukla
    I am trying to install Ubuntu 12.04 on my HP Mini 110 with 2 gb of ram and Windows 7 starter edition. However, when I try to boot from USB, the Ubuntu screen loads and then shows the message-'General Error Mounting Filesystem'. I have to press Ctrl+D to reboot, and the same process starts again until I remove my pen drive. I have tried making a Live USB from UNetBootin and the software Ubuntu suggests, downloaded from pendrivelinux.com. However, Ubuntu still won't load. I am new to the Ubuntu world and don't know what to do, please help.

  • web server response code 500

    - by Bryan Kemp
    I realize that this may spur a religious discussion, but I discussed this with friends and get great, but conflicting answers and the actual documentation is of little help. What does the 500 series response codes mean from the webserver? Internal Server Error, but that is vague. My assumption is that it means that something bad happened to the server (file system corruption, no connection to the database, network issue, etc.) but not specifically a data driven error (divide by zero, record missing, bad parameter, etc). Something to note, there are some web client implementations (the default Android and Blackberry httpclients) that do not allow access to the html boddy if the server response is 500 so there is no way to determine what caused the issue from the client. What I have been been implementing recently is a web service that returns a json payload wrapped in a response object that contains more specific error information if it is data related, but the server response will be 200 since it finished the actual processing. Thoughts?

  • Mobile Development Competition

    - by Oscar
    I think this is the correct website to ask this question, if it is not, I am sorry. I want to start learning mobile device development, but I am someone that gets much more motivated when there is some goal to reach. Because of that, I would like to join a competition. I know about Microsoft Imagine Cup, which is a very nice competition. Does anyone knows another mobile development competition with a deadline in the next 6~8 months? I have been googling for it, but I could not find any, maybe someone knows about something that I couldn't find. Thanks for your help :)

  • How does Ubuntu One sync two machines with identical file content?

    - by user27449
    I have a notebook and a desktop computer, both running Ubuntu 11.10. I used to sync between the two with the help of Unison, so both computers have identical content in the Documents folder. I decided to try UbuntuOne. My question is, if I activate UbuntuOne for the two machines for the folders with identical contents, will UbuntuOne be able to recognise that, or will it sync to the cloud everything twice (and then down on the other machine). To put it another way, will I end up having two copies of everything on the machines and on the cloud, and therefore should delete the identical files on one of the machines before activating UbuntuOne, or not. Thank you, and if there is already something on the net about this, I'd be glad if somebody posted the link here.

  • Testing on Device Other Than the Known Brand Question (Local and Imported Phone Question)

    - by David Dimalanta
    I have a question. When testing a device by using Eclipse, it's easy to install and add device software with these specific brands commonly used in game testing like Samsung, Google, T-Mobile, and HTC; according to the Android Developers website. What if I'm using other brands that runs on Android to test the program via Eclipse (i.e. MyPhone, Starmobile), what should I look for to download in order to enable testing phones that those brands are using other than the brands that are known and commonly used: model number or simply brand? Here's some examples of these brands other than the brands we've known that runs on Android: Starmobile Engage 7 (http://www.lazada.com.ph/Starmobile-Engage-7-Android-40-4GB-with-Wi-Fi-Black-Starmobile-Mercury-B201-COMBO-39833.html/) My|Phone A898 Duo (http://www.myphone.com.ph/#!a898-duo/c1yt) Also, take note that I'm a Filipino programmer working at the Philippines to test our local smartphones for the created Android game or app. Hope you can understand me for my help.

  • OData where art thou?

    - by Brian
    Douglas Purdy explains. I think the best part will be the governmental aspect. All public record should be available in a way that’s easy to query IMHO. From the article: Many of us at Microsoft believe the OData protocol can help usher in a more open and programmable Web by creating a common funnel to expose rich data, thereby creating a world of customized consumer mash-ups; a world where government data is transparent and accessible to any citizen; a world where you can ask a question and know, “There’s a feed for that.” Do check out www.odata.org, and while you’re at it, check out codename Dallas. For all those government IT workers out there, consider the savings. No need to pay someone to format the data for a specific department or constituent. Just put it online and point them there.

  • EU Digital Agenda scores 85/100

    - by trond-arne.undheim
    If the Digital Agenda was a bottle of wine and I were wine critic Robert Parker, I would say the Digital Agenda has "a great bouquet, many good elements, with astringent, dry and puckering mouth feel that will not please everyone, but still displaying some finesse. A somewhat controlled effort with no surprises and a few noticeable flaws in the delivery. Noticeably shorter aftertaste than advertised by the producers. Score: 85/100. Enjoy now". The EU Digital Agenda states that "standards are vital for interoperability" and has a whole chapter on interoperability and standards. With this strong emphasis, there is hope the EU's outdated standardization system finally is headed for reform. It has been 23 years since the legal framework of standardisation was completed by Council Decision 87/95/EEC8 in the Information and Communications Technology (ICT) sector. Standardization is market driven. For several decades the IT industry has been developing standards and specifications in global open standards development organisations (fora/consortia), many of which have transparency procedures and practices far superior to the European Standards Organizations. The Digital Agenda rightly states: "reflecting the rise and growing importance of ICT standards developed by certain global fora and consortia". Some fora/consortia, of course, are distorted, influenced by single vendors, have poor track record, and need constant vigilance, but they are the minority. Therefore, the recognition needs to be accompanied by eligibility criteria focused on openness. Will the EU reform its ICT standardization by the end of 2010? Possibly, and only if DG Enterprise takes on board that Information and Communications Technologies (ICTs) have driven half of the productivity growth in Europe over the past 15 years, a prominent fact in the EU's excellent Digital Competitiveness report 2010 published on Monday 17 May. It is ok to single out the ICT sector. It simply is the most important sector right now as it fuels growth in all other sectors. Let's not wait for the entire standardization package which may take another few years. Europe does not have time. The Digital Agenda is an umbrella strategy with deliveries from a host of actors across the Commission. For instance, the EU promises to issue "guidance on transparent ex-ante disclosure rules for essential intellectual property rights and licensing terms and conditions in the context of standard setting", by 2011 in the Horisontal Guidelines now out for public consultation by DG COMP and to some extent by DG ENTR's standardization policy reform. This is important. The EU will issue procurement guidance as interoperability frameworks are put into practice. This is a joint responsibility of several DGs, and is likely to suffer coordination problems, controversy and delays. We have seen plenty of the latter already and I have commented on the Commission's own interoperability elsewhere, with mixed luck. :( Yesterday, I watched the cartoonesque Korean western film The Good, the Bad and the Weird. In the movie (and I meant in the movie only), a bandit, a thief, and a bounty hunter, all excellent at whatever they do, fight for a treasure map. Whether that is a good analogy for the situation within the Commission, others are better judges of than I. However, as a movie fanatic, I still await the final shoot-out, and, as in the film, the only certainty is that "life is about chasing and being chased". The missed opportunity (in this case not following up the push from Member States to better define open standards based interoperability) is a casualty of the chaos ensued in the European Wild West (and I mean that in the most endearing sense, and my excuses beforehand to actors who possibly justifiably cannot bear being compared to fictional movie characters). Instead of exposing the ongoing fight, the EU opted for the legalistic use of the term "standards" throughout the document. This is a term that--to the EU-- excludes most standards used by the IT industry world wide. So, while it, for a moment, meant "weapon down", it will not lead to lasting peace. The Digital Agenda calls for the Member States to "Implement commitments on interoperability and standards in the Malmö and Granada Declarations by 2013". This is a far cry from the actual Ministerial Declarations which called upon the Commission to help them with this implementation by recognizing and further defining open standards based interoperability. Unless there is more forthcoming from the Commission, the market's judgement will be: you simply fall short. Generally, I think the EU focus now should be "from policy to practice" and the Digital Agenda does indeed stop short of tackling some highly practical issues. There is need for progress beyond the Digital Agenda. Here are some suggestions that would help Europe re-take global leadership on openness, public sector reform, and economic growth: A strong European software strategy centred around open standards based interoperability by 2011. An ambitious new eCommission strategy for 2011-15 focused on migration to open standards by 2015. Aligning the IT portfolio across the Commission into one Digital Agenda DG by 2012. Focusing all best practice exchange in eGovernment on one social networking site, epractice.eu (full disclosure: I had a role in getting that site up and running) Prioritizing public sector needs in global standardization over European standardization by 2014.

  • Collision Detection algorithms with early Collision exit

    - by Grieverheart
    I'm using collision detection in Monte Carlo simulations and at the moment I'm using GJK which is quite fast. I can't help to think it could be done even faster though. In the simulations, about 70% of the time GJK is run, it detects a collision. Thus collisions are more than non-collisions in my case. Most collision detection algorithms I know have an early non-collision exit test. Are there any collision detection algorithms that have an early collision detect instead of non-collision and could be potentially faster than GJK in case of collision?

  • SEO optimization for AJAX site and dynamic HTML canvas

    - by Christian Benincasa
    I have a site that uses AJAX to query the Last.fm database and then dynamically draws a graph of the results on an HTML canvas. In the search function, I have a command that sets window.location.hash to the search parameters. I also have a function that checks if a hash was provided in the url and if so, generates the page. For example, http://www.thenlistento.com/#!/led+zeppelin will automatically navigate to a search page for Led Zeppelin. My question is, how do optimize this set up for SEO? Can it be done at all? I've taken a look at Google Webmaster Docs and read over the hashbang protocol, but I'm not totally sure how to apply it to my situation..or even if I can at all. Any help/suggestions would be greatly appreciated. Link to the site: http://www.thenlistento.com

  • 12.04 - Connecting Acer X203H monitor to new Dell XPS 15z laptop

    - by Lucy Dixon
    I have installed the latest version of Ubuntu (12.04) on my boyfriend's new Dell XPS 15z laptop. He uses a Microsoft wireless keyboard and mouse, and an Acer X203H monitor with his set-up. No problems with the keyboard or mouse, or with connecting the HP printer, but we just can't get the laptop to talk to the Acer monitor. With his old setup he used a VGA cable to connect machine & monitor. New laptop has no VGA port, but we've bought a VGA to HDMI adaptor to connect to the laptop. Have tried using Fn F2 to change the display from laptop to monitor, but it doesn't see the monitor at all. HELP! Is there a driver I can install from somewhere? Or how can I tell Ubuntu to look for the monitor on another port? Completely in the dark, and about to get in trouble!! Thanks

    Dear beloved community! I accidentally disabled some applications from the notifications bubble. I was wondering, how can I renable the hidden applications again? I found a few answers on askubuntu and the ubuntu forums, but unfortunately the information no longer corresponds properly to the actual file system (e.g: dconf-editor - apps - nm-applet - "disable-connected-notifications" and "disable-disconnected-notifications" are disabled "unchecked", does no longer apply, I can't see anything in there except stamp = value 3). Any help would be greatly appreciated! Have a nice day!

  • Building small Ubuntu server - What hardware is recommended?

    - by 10robinho
    There are many of us who need to build small Ubuntu server. Problem is that in some countries it is hard to find and quite expensive to buy server motherboards and processors. And when one is building small server with limited budget, buying some Xenons is not really an option. So, are there any general recommendations for hardware (I think that motherboards are the main issue) that is stable and fast under Linux? I read that Intel should be the best choice for cpu + mbo combo. So, I was looking around for some Intel motherboards + i7 Ivy Bridge (like Intel DZ77BH-55K with Z77 chipset and Intel i7 3770K) but I've read that they have some issues with kernel, booting and USB ports. That is why I ask community if you have any experience with this. Maybe Intel is not the best choice here? Maybe ASUS or Gigabyte or _other company_ are more stable with Linux? I hope that this Q&As can help people in building stable Ubuntu server.

  • XNA - Drawing 2D Primitives (Boxes) and Understanding Matrices in Computer Graphics

    - by MintyAnt
    I have two issues which I wish to solve by creating 2D primitives in XNA. In my game, I wish to have a "debug mode" which will draw a red box around all hitboxes in the game (Red outline, transparent inside). This would allow us to see where the hitboxes are being drawn AND still have the sprite graphics being drawn. I wish to further understand how matrices work within computer graphics. I have a basic theoretical grasp of how they work, but I really just want to apply some of my knowledge or find a good tutorial on it. To do this, I wish to draw my own 2D primitives (With Vertex3's) and apply different transormation matrices to them. I was trying to find a tutorial on drawing primitives using Direct3D, but most tutorials are only for c++, and just tell me to use XNA's Spritebatch. I wish to have more control over my program than just with Spritebatch. Any Help on using Direct3D or any other suggestions would greatly be appreciated. Thank you.

  • Looking for an open source project in Python

    - by Roman Yankovsky
    I am looking for practical tasks to get experience with Python. Just reading the books and not doing any tasks in the language is not effective. I solved some problems on the Project Euler and TopCoder and it helped me to learn the syntax of the language better. But those tasks are hard algorithmically, but as a rule is quite simple from the point of view of programming. Now I'm looking for an interesting open source project in Python, participation in which will help me to better understand the OO-model of language. Although, this is my first step with Python, in general, I am an experienced programmer and I can be useful for a project. May be someone can suggest something?
