  • Help! Online upgrade from 12.04 to 14.04 stuck

    - by Luis
    I was trying to upgrade my Lenovo T500 laptop from Kubuntu 12.04 LTS to Kubuntu 14.04 LTS. Fired up the upgrade process, and finally after downloading a zillion packages the upgrade got going, only to get stuck... It has been stuck for hours on: Installing the upgrades->Unpacking subversion Last lines of error messages: GLib-GObject-CRITICAL **: /build/buildd/glib2.0-2.32.4/./gobject/gtype.c:2722: You forgot to call g_type_init() at /usr/lib/perl/5.18/DynaLoader.pm line 207. GLib-CRITICAL **: g_once_init_leave: assertion `result != 0' failed at /usr/lib/perl/5.18/DynaLoader.pm line 207. I don't care much about subversion anymore, I use git now; I don't care if subversion ends up in a bad state and I have to remove it... I just want the upgrade to continue, and hopefully complete. Any ideas???? Thanks, Luis

  • Meet our 2009 Oracle Graduates in South Africa

    - by anca.rosu
    Focusing on the broader Oracle community, Oracle South Africa initiated its first skills development programme in May 1988. Since its inception the programme has developed and improved and every year more graduates are taken on board. The Oracle Graduate Programme is made up of specific learning paths designed around customer, partner and Oracle specifications and is structured to meet the urgent skills requirements in the Oracle “economy”. The training programmes have a specific duration and incorporate both theoretical and practical application of Oracle product sets. It is aimed at creating: Meaningful employment for graduates; Learning opportunities for individuals within the organization so that career growth opportunities are exploited to the fullest; Capacity building for small enterprises which is aligned to Oracle’s Enterprise Development Programme Meet our five graduates who joined us in December 2008 and have spent over a year with us! Let’s get their initial feedback on the graduate programme and on their assignment to Jordan. Lector   On the Oracle Graduate Programme: “The Oracle Graduate Programme is an experience of a life time. I would not trade it for anything. It’s challenging and rewarding. I am proud and happy to be in an organization like Oracle” On the assignment in Jordan: "Friendly, welcoming people, world class instructors always willing to go the extra mile. What more can you ask for?"   Lungile On the Oracle Graduate Programme: “I joined Oracle as part of the graduate intake for pre-sales in order to develop my skills and knowledge. Working at Oracle has been an overwhelmingly positive experience as it has encouraged me to progress with my personal development. I am hugely grateful. It has been a great challenge and an awesome opportunity.” On the assignment to Jordan: “Going to Jordan was a great opportunity and the experience of a lifetime. The people were very welcoming and friendly. The culture was totally different from ours - the food, the clothes and the weather. It was an amazingly different experience to work from Sunday to Thursday with Friday and Saturday as the weekend.” Thabo On the Oracle Graduate Programme: “Life is an infinite learning path. I truly value growth. I believe for one to grow, one needs to be challenged to your full potential. The Oracle Graduate Programme offers real growth – and so much more.” On the assignment to Jordan: “I was amazed by the cultural differences. I now understood that to be part of the global community, I must embrace our similarities and understand our differences.”   Albeauty On the Oracle Graduate Programme: “Responsibility, dedication, focus and taking initiative … these are the key points I learned from Oracle. It is such an honour to finally be part of the Oracle family. The graduate programme itself was a great experience as I managed to learn how Oracle operates – it has been the highlight of my year. I believe that my hard work will assist in the growth of the company.” On the Jordan assignment: “A memory worth embracing. Going to Jordan was a great opportunity as I learned a lot with respect to integration between different cultures and getting to adapt to all things different. I, along with almost every other graduate, discovered that Oracle is far more than a database company. Now I know there is far more to the ‘Big Red’ name.” Emmanuel On the Oracle Graduate Programme: “The programme gave me invaluable exposure to the ICT sector and also provided an opportunity to travel, network and exchange ideas with others. The formal training helped me to improve my presentation skills and gave me a better understanding of business etiquette and communication.” On the assignment to Jordan: “It was my first trip abroad. It was a great chance to get to know each other. I had the opportunity to share ideas, share personal stuff as a team. We met experts who gave us superb training in Oracle Technologies. It was great.”   If you have any questions related to this article feel free to contact  [email protected].  You can find our job opportunities via http://campus.oracle.com.   Technorati Tags: Oracle community,South Africa,Graduate Programme,Jordan,Technologies

  • What Contents in a Young Programmer's Personal Website

    - by DotNetStudent
    I recently stumbled upon this question in which the contents a professional programmer's website should have were discussed and I agree with most of the answers there. However, I am by no means a professional programmer (just came out from university) and so I am a bit lost in what concerns the contents I should provide in the personal website I am designing for myself now. I do have a pretty nice job at a fast-growing software company but I would really like to present myself to the outside world in a nice but humble manner since my curriculum is by no means a long one. Any ideas?

  • Problem with DNS

    - by dotNET
    Hey, I bought a new website, and the company gived me another free domain name, so when I asked for the socond they created it and they told me to change the DNS to look like the first one. It's been a week waiting for it to propagate, today when I type the url I got this error message : If you are the web site owner, it is possible you have reached this page because: * The IP address has changed. * There has been a server misconfiguration. * The site may have been moved to a different server. If you are the owner of this website and were not expecting to see this page, please contact your hosting provider. When I try to add the second domain to my cpanel (Addon domain) I get also another error : The addon domain “abcdef.com” has been created. An account with that login already exists. Do you have any ideas about this problem. Thanks. EDIT I tried to flush the DNS with ipconfig /flushdns, but It's not changing anything.

  • How to enable wireless on my hp compaq nx6110 laptop

    - by victor
    My laptop is an old HP Compaq NX6110. The wireless switch is not working, and I can`t also enable wireless from connexion manager. I connected to to the Internet with Ubuntu using wired LAN, and I downloaded windows wireless drivers, Wi-Fi radar application, and additional drivers. I also updated to Ubuntu 11.10 but still no luck. I guess I need some terminal commands. Any ideas are welcome. Thank you for the attention victor.

  • How to capitalize maximally on location-independence … my personal #1-incentive for working as a developer

    - by SomeGuy
    To me the ultimate beauty in working as a developer is the fact that given a nice CV, your are going to find a new job, everywhere at any time. So I would like to ask if somebody here as experience in working while travelling for example. Or job-hopping from metropolis to metropolis every, say, six months. For example I have been investigating for how to get to Brazil. But it seems like that working as an employee in Brazil would be no option, b/c it takes a lot of time/money/effort to get the proper visas and permissions. So the only practical solution would be to freelance and the just travel, while getting your job done wherever you are. I bet my ass that there are loads of IT-guys out there and on here who know exactly what I am talking about. I'm looking forward to interesting ideas and stories.

  • How to keep menu in a single place without using frames

    - by TJ Ellis
    This is probably a duplicate, but I can't find the answer anywhere (maybe I'm searching for the wrong thing?) and so I'm going to go ahead and ask. What is the accepted standard practice for creating a menu that is stored in a single file, but is included on every page across a site? Back in the day, one used frames, but this seems to be taboo now. I can get things layed out just the way I want, but copy/pasting across every page is a pain. I have seen php-based solutions, but my cheap-o free hosting doesn't support php (which is admittedly a pain, but it's a fairly simple webpage...). Any ideas for doing this that does not require server-side scripting?

  • "Build your own website" - Developing a CMS with Vague Requirements on a Tight Deadline

    - by walnutmon
    I'm a Java developer in charge of making a product which allows clients to "build their own site". I've spent a lot of time looking into Liferay, as I don't have any experience in building CMSs, and want to either use it, or get ideas of how to build a decent system. The time line is short, requirements are vague, yada yada Is Liferay a good technology to work with when showing the client (who may be very low on computer expertise) a user interface to build a site? The thing is, I want the power and flexibility to avoid the learning curve in building a CMS like product, but I don't want to waste time learning a new technology only to find its over-kill, or can't do the simple - but uncommon and unimplemented - things that we are asked to add as features Ideally I'd like to provide multiple web interfaces to the core API to build the sites - one that is very powerful, and another that is watered down and easy to use.

  • HP Deskjet 720C USB printer doesn't finish

    - by 213441265152351
    I have an HP Deskjet 720C connected through a USB cable to an Ubuntu 12.04 laptop. When I plugged the printer for the first time into the fresh 12.04 laptop install, it auto-detected the printer correctly and choose the recommended drivers without a problem. The document print fine until they reach the end of the last page, then suddenly stop just about the end leaving the page unfinished. I have checked that the margins are the correct ones. I have the latest version of cups installed. I have also tried changing the options of usb-unidir-default and usb-no-reattach-default via lpadmin, but the printing stops even earlier. EDIT: It seems like the problem is with the last page. So if I am printing 3 pages, the first two work well but the last few lines in the last page are not printed. Any ideas?

  • Slot Machine Pay Out

    - by Kris.Mitchell
    I have done a lot of research into random number generators for slot machines, reel stop calculations and how to physically give the user a good chance on winning. What I can't figure out is how to properly insure that the machine is going to have a payout rating of (lets say) 95%. So, I have a reel set up wit 22 spaces on it. Filled with 16 different symbols. When I get my random number, mod divide it by 64 and get the remainder, I hop over to a loop up table to see how the virtual stop relates to the reel position. Now that I have how the reels are going to stop, do I make sure the payout ratio is correct? For every dollar they put in, how to I make sure the machine will pay out .95 cents? Thanks for the ideas. I am working in actionscript, if that helps with the language issues, but in general I am just looking for theory.

  • Installing Ubuntu 14.04 on macbook pro EFI

    - by user279771
    Macbook pro: mavericks, 5.2, graphics: nvidia geforce 9600M I followed the guides from here: https://help.ubuntu.com/community/UEFIBooting#Detect_.28U.29EFI_firmware_processor_architecture and http://www.rodsbooks.com/ubuntu-efi/. What I have is the following: /dev/sda apple partitions /boot / (root) swap When installing ubuntu, I did not install the boot loader during installation but did so in a chroot environment after installing grub-efi. I installed grub to /dev/sda1 (efi) which created the grub64.efi file in efi/ubuntu. This allows the refined boot manager to bring up grub and select ubuntu however, the graphics does not work. Even after adding nomodeset and removing quiet/splash from the kernel parameters. Any ideas on what could be wrong? To be clear, if I remove quiet/splash, I can see all the text startup messages being printed out however, the display manager doesn't appear to start (the screen stays black). Oddly enough though, the ubuntu startup sound can be heard.

  • Unity 2d support dropped in 12.10, what now?

    - by tomodachi
    So its been announced. Ubuntu is dropping unity 2d support. I wouldn't mind if it wasn't for two things that are important to me. 1) A working system Unity is nice, i try to use it quite often. But it lags. 2) Support for older hardware. I also have old computers. You can imagine how they would work with unity if my current laptop is slog in Ubuntu. I guess i could use another desktop environment/ window manager , like switching to fluxbox. Anyone have any suggestion ideas/solutions on how to proceed with Ubuntu in the future? All insights welcome

  • SEO Metatags in Web Forms and MVC

    - by Mike Clarke
    Has anyone got any ideas on where we should be adding our SEO metadata in a Web Forms project? Why I ask is that currently I have two main Masterpages, one is the home page and the other one is every other page, they both have the same metadata that’s just a generic description and set of key words about my site. The problem with that is search engines are only picking up my home page and my own search engine displays the same title and description for all results. The other problem is the site is predominantly dynamic so if you type in a search for beach which is a major categories on the site you get 10000 results that all go to different information but all look like a link to the same page to the user. edit It's live here www.themorningtonpeninsula.com

  • What do you do to get your software design robust, flexible and clear?

    - by Oscar
    I am still getting mature as a software engineering/designer/architect, as you may want to call. At this point in time, I am getting small projects, private projects and so on. What I noticed is that even though I think about the SW structure, design some diagrams, have they really clear in my mind when I start coding, at the end, my software is not flexible and clear as I would like to. I would like to ask you what kind of approaches, mechanisms or even tricks do you use, to get your software (and SW design) flexible, robust and clear (easy to understand and use). So.... Any ideas to give to a beginner?

  • CMS DITA North America Conference / Agile Doc

    - by ultan o'broin
    I attended and presented, along with a colleague, at the Content Management Strategies DITA North America Conference 2010 in Santa Clara this week. It was touch and go whether I would make it across the Atlantic, but as usual the Irish always got through! Our presentation was about DITA and Writing Patterns, and there was three other presentations from Oracle folks too, all very well delivered and received. The interaction with other companies was superb, and the sparks of innovation that flew as a result left me with three use case ideas for UX investigation and implementation. My colleague had a similar experience. Well worth attending! One of the last sessions was about Authoring in an Agile environment, presented by Julio Vasquez. This was an excellent, common sense, and forthright no-nonsense delivery that made complete sense to me. I'd encourage you, if you are interested in the subject, to check out Julio's white paper on the subject too, available from the SDI website.

  • Do 2D games have a future? [closed]

    - by Griffin
    I'm currently working on a 2D soft-body physics engine (since none exist right now -_-), but I'm worried that there's no point to spending what will most likely be years on it. Although I love working on it, I doubt such an engine would get any income considering anyone willing to pay money for the library will likely to be working in 3D. Do 2D games have any sort of future in the game industry? Should I just drop my engine and find something meaningful to work on? Bonus: I've been trying to think of a unique way to implement my physics engine in a 2d game by looking at games that are multiple dimensions, but still in 2d perspective like Paper Mario. Any ideas?

  • Read Only usb stick that won't let me do anything to it

    - by Jonathon
    Somehow I messed up and accidentally made my usb stick into a read only file system. I have tried a bunch of things to delete the files, including the basic (rm -f myfile) and attempting to allow writing (sudo chmod +w myfile) and then deleting, but none of this seems to work. Any ideas on what I can do. I don't have anything on the usb stick that I need, but I don't want to throw away an otherwise perfectly good piece of equipment. How can I make it work? Am I going about this completely the wrong way?

  • Diagonal line of sight with two corners

    - by Ash Blue
    Right now I'm using Bresenham's line algorithm for line of sight. The problem is I've found an edge case where players can look through walls. Occurs when the player looks between two corners of a wall with a gap on the other side at specific angles. The result I want is for the tile between two walls to be marked invalid as so. What is the fastest way to modify Bresenham's line algorithm to solve this? If there isn't a good solution, is there a better suited algorithm? Any ideas are welcome. Please note the solution should also be capable of supporting 3d. Edit: For the working source code and an interactive demo of the completed product please see http://ashblue.github.io/javascript-pathfinding/

  • Any idea for a master thesis in software engineering

    - by medusa
    Hi! I have to choose a thesis for my master degree. Time is limited to about 6 months. Do you have any idea? Any personal thesis that was successful? After searching around for some time now, i see the most famous topics are related to artificial intelligence, but i don't want something like that, because most of it would be just theory and boring. A lot of students present these kind of studies because those are the most difficult. I would prefer something that does not necessary include that mathematical complexity but which is an everyday-life topic, and gives concrete ideas, hypothesis, or solutions to some actual problems. Hope i gave my whole idea: i am looking for something that is different from the majority of what all students do, and able to impress the audience... :) I would really really appreciate any your suggestion, Thank you!

  • Best practices for coding date sensitive websites

    - by Duopixel
    I'm creating a website for an event that is coming up. It has some functionality related to the event (such as "send me a reminder"), other stuff that takes place during the event, and finally some stuff that comes after the event. I need to start working on code that takes place during the event and after the event, plus some fixes for the current site (which is already live). What is the best way to approach this problem? Some solutions that occur to me are creating branches for each state and merging stuff as needed. Other one is hiding and showing functionality based on the date, i.e if (currentDate < eventDay) { reminder.show();}. Ideas?
