  • Black Screen When Booting From .VDI Image

    - by GTyler
    I have cloned a VirtualBox machine, which runs Ubuntu 11.04 32-bit as Guest OS. I now wish to transfer it to a new host machine running Windows Vista 32-bit. I’ve transferred the .vdi file and adjusted the name and memory. However when I boot it, the options to choose the Linux version came up: Ubuntu, with Linux 2.6.38-10-generic, Linux 2.6.38-10-generic(recovery mode) , Previous Linux versions, Memory test. Once I chose Linux 2.6.38 a black screen just appears with an underscore at the top. What should I do to get it to run? I don’t have my original machine near me now so I can only work with my .vdi image. My VB is version 4.0.10. I have tried cloning this VDI and also assigning a new UUID and making a new guest, but I still got the black screen. Thank you.

  • Backup systems config files

    - by David ???
    I'm planning on installing nVidia proprietary drivers on my Ubuntu 10.10. Historically this always ends-up with me being left with no graphical interface. No ability to revert - and reinstalling the whole system. So now, before trying this anew, I wish to backup all relevant config files. I'll try 1 or 2 methods. I'll list each one's commands. I'll appreciate if anyone can tell me how to backup the relevant file, or what's the reverse of this operation. 10x, David Method I - as described here: apt-get --purge remove xserver-xorg-video-nouveau As described in this answer: edit /etc/default/grub and add the line GRUB_CMDLINE_LINUX="nouveau.modeset=0" sudo update-grub Reboot Install original drivers downloaded from nVidia site. Method II - as described here: sudo apt-get purge nvidia* [possibly 'sudo gedit /etc/modprobe.d/blacklist.conf' adding 'vga16fb' 'nouveau' sudo apt-get install nvidia-glx-185 sudo modprobe nvidia sudo lsmod | grep -i nvidia sudo nvidia-xconfig

  • Time To Consider Getting Your Oracle Certification?

    - by Paul Sorensen
    Hi Everyone,I recently read an interesting study from Global Knowledge titled: 2010 IT Skills and Salary Report which contains a lot of great information related to IT worker trends including roles, required skills, demographics, salaries and more. I had to dig a little bit, but the report indicates that certification is valued by the majority of managers and those become certified, which underscores the results of our own surveys that show how certification is valued by IT workers, their employers and their customers.Additionally, if you look a little closer you will also find average salaries for those who are Oracle certified. Their salary figures are impressive and are among the top salaries of the certifications listed.If you have ever considered becoming certified or are in the process of becoming certified, I encourage you to look at the Global Knowledge study. With an ever-increasing suite of Oracle certifications available to you, there may be something within our certification offerings that will help you increase your skills, build your career, and gain additional credibility.Thank you,QUICK LINKSGlobal Knowledge 2010 IT Skills and Salary ReportOracle Certification 2009 Salary SurveyOracle Certification web site

  • Silverlight: Creating great UIs

    - by xamlnotes
    I was always told I was left brained and could not draw. And I bought into that view. Somewhere down the road years ago I did learn to play guitar and to play by ear at that.  Now that’s not all left brained so my right brain must be working.  About a year ago, my good friend Billy Hollis turned me own to a book by Betty Edwards (http://www.drawright.com/).  I started reading this and soon I found my self drawing on napkins in restaurants while we were waiting on food and at many other times too.  Dang’d if I could not draw! Check out my UI article at Dev Pro Connections (Great UIs article) on some of my experiences. Heres a few more links that are really cool too. Cool color combinations web site Simply painting is awesome. Saw this guy on tv. This site has some great tools for color contrasting

  • Best way to prevent UIPanGestureRecognizer from firing when moving sprites in cocos2d

    - by cjroebuck
    Im using UIPanGestureRecognizer in my cocos2d game to do drag and drop of sprites. I have a row of sprites and when I drag a sprite on top of another one, the sprite underneath it and any other sprites between should shift left or right out of the way to allow space to drop the currently selected sprite. This is working ok, however, if I am too quick at dragging the sprite around the screen, this triggers another round of the UIPanGestureRecognizer's callback method, and screws up the logic, as the sprites are in-between shifting. I need a way to freeze the callback from firing, whilst the other sprites are shifting, then once they have finished moving, re-enable the callback to fire. Whats the best way to do this?

  • RIA Services and Validation

    Earlier today, my SilverlightTV recording on RIA Services and Validation went online. I used validation as a feature area to focus on this first recording on RIA Services, because I think it illustrates both the RIA Services value proposition and key elements of the vision around the project in a very direct manner. Specifically: Focus on end-to-end solutions for data scenarios. It is not sufficient to just address querying data or submitting some changes, but about providing the infrastructure...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • KnockoutJS 2.3.0 - Uncaught Error: You cannot apply bindings multiple times to the same element.

    - by Aligned
    Originally posted on: http://geekswithblogs.net/Aligned/archive/2013/07/25/knockoutjs-2.3.0---uncaught-error-you-cannot-apply-bindings-multiple.aspxI upgrade KnockoutJs through Nuget and started getting the error ‘Uncaught Error: You cannot apply bindings multiple times to the same element.’ when I used applyBindings after the main page load. I had some dynamically added DOM elements and re-applying bindings worked before. It always seemed like a workaround/hack, but now Knockout is telling me that I shouldn’t do it. The quick way to fix this is to use ko.cleanNode($(‘#id’) and this works. A different/possibly better way, as suggested by x0n might be to use templates and Knockout’s template binding (<script type=’text/html’>…</script>).   Thanks again to the StackOverflow community for quickly providing me with the solution. Check out my question for all the details.

  • How will Deja-Dup operates when backing up to an external USB drive?

    - by Little Bobby Tables
    I want to set up regular backups, and deja-dup seems like a nice tool. However, I want to put my backups on an extension USB drive that I have, not on a remote network location. Naturally, this drive is not always connected. If I configure deja-dup to backup to a directory on this drive (e.g. /media/extention/backup), what would happen? Will it prompt me to connect the drive when it is missing (the desired behavior), or just fail silently? Is there some way to tweak it to do so? I can roll my own cron-based backup script that checks if this drive is mounted, but I would really prefer to use an existing, integrated tool.

  • Seeking a free Lint for C which programmers will *want* to use

    - by Mawg
    When I try to persuade others to Lint their code I always get excuses - too difficult to set up, too difficult to understand, false positives, etc (most of which translates to too lazy, too stupid or too afraid of new things). Is there any way that I can make Linting easier? We code in C using Netbeans. Can I incorporate Splint into Netbeans? I did find a Splint GUI which was quite good, but there was no way to lint a directory tree. Any ideas? Thanks in advance

  • Taking a Flying Leap

    - by Lance Shaw
    Yesterday, I went skydiving with three of my children.  It was thrilling, scary, invigorating and exciting. While there is obvious risk involved, the reward and feeling of success was well worth it. You might already be wondering what skydiving would have to with WebCenter, so let me explain. Implementing a skydiving program and becoming an instructor does not happen overnight.  It does not happen with the purchase of the needed technology. Not one of us would go out, buy a parachute, the harnesses, helmet and all the gear and be able to convince anyone that we are now ready to be a skydiving instructor. The fact is that obtaining the technology is merely a small piece of the overall process and so is the case with managing content in your company. You don't just buy the right software (Oracle WebCenter Content) and go to your boss and declare information management success. There is planning, research and effort that goes into deploying software of any kind and especially when it is as mission-critical to the success of your business as Enterprise Content Management. To become a certified skydiving instructor takes at least 3 years of commitment and often longer. In the United States, candidates must complete over 500 solo jumps of their own over a minimum of 36 months and then must complete additional rigorous training under observation.  When you consider the amount of time and effort involved, it's not unlike getting a college degree and anyone that has trusted their lives to one of these instructors will no doubt appreciate their dedication to the curriculum.  Implementing an ECM system won't take that long, but it certainly requires commitment, analysis and consideration. But guess what?  Humans are involved and that means that mistakes can happen and that rules change.  This struck me while reading an excellent post on darkreading.com by Glenn S. Phillips entitled "Mission Impossible: 4 Reasons Compliance is Impossible".  His over-arching point was that with information management and security, environments change and people are involved meaning the work is never done.  He stated that you can never claim your compliance efforts are complete because of the following reasons. People are involved.  And lets face it, some are more trustworthy than others. Change is Constant. There is always some new technology coming along that is disruptive. Consumer grade cloud file sharing and sync tools come to mind here. Compliance is interpreted, not defined.  Laws and the judges that read them are always on the move. Technology is a tool, not a complete solution. There is no magic pill. The skydiving analogy holds true here as well.  Ultimately, a single person packs your parachute.  For obvious reasons, you prefer that this person be trustworthy but there are no absolute guarantees of a 100% error-free scenario.  Weather and wind conditions are never a constant and the best-laid plans for a great day of skydiving are easily disrupted by forces outside of your control.  Rules and regulations vary by location and may be updated at any time and as I mentioned early on, even the best technology on its own will only get you started. The good news is that, like skydiving, with the right technology, the right planning, the right team and a proper understanding of the rules and regulations that govern your industry, your ECM deployment can be a great success.  Failure to plan for any of the 4 factors that Glenn outlined in his article will certainly put your deployment and maybe even your company at risk, so consider them carefully. As a final aside, for those of you who consider skydiving an incredibly dangerous and risky pastime, consider this comparative statistic.  In 2012, the U.S. Parachute Association recorded 19 fatal skydiving accidents in the U.S. out of roughly 3.1 million jumps.  That’s 0.006 fatalities per 1,000 jumps. By comparison, the U.S. National Highway Traffic Safety Administration reports that there were 34,080 deaths due to car accidents in 2012.  Based on the percentages, one could argue that it is safer to jump out of a plane than to drive to the airport where the skydiving will take place. While the way you manage, secure, classify, control, retain and dispose of company files may not carry as much risk as driving or skydiving, it certainly carries risk for the organization when not planned and deployed appropriately.  Consider all the factors involved in your organization as you make your content management plans.  For additional areas of consideration, be sure to download our free whitepaper on the topic entitled "The Top 10 Criteria for Choosing an ECM System" which is available for download here.

  • How to Align Gun with Bullets

    - by Shane
    I have a top-down 2D shooter. I have an image of a player holding a gun, that rotates to face the mouse. Please note that the gun isn't a separate image tethered to the player, but rather part of the player. Right now, bullets are created at the player's x and y. This works when the player is facing the right way, but not when they rotate. The bullets move in the right direction, but don't come from the gun. How can I fix this? TL;DR: When the player rotates, bullets don't come from gun. public void fire() { angle = sprite.getRotation(); System.out.println(angle); x = sprite.getX(); y = sprite.getY(); Bullet b = new Bullet(x, y, angle); Utils.world.addBullet(b); }

  • Arbitrary projection matrix from 6 arbitrary frustum planes

    - by Doub
    A projection matrix represent a tranformation from the camera view space to the rendering system clip space. In other words, it defines the transormation between a 6-sided frustum to the clip cube. The glOrtho and glFrustum use only 6 parameter to define such a projection, but impose several constraints on the frustum that will get projected to the clip cube: the near and far planes are parallel, the left and right planes intersect on a vertical line, and the top and bottom planes intersect on a horizontal lines, both lines being parallel to the near and far planes. I'd like to lift these restrictions. So, from the definition of the 6 frustum side planes (in whatever representation you see fit), how can I compute a general projection matrix?

  • How can I install a specific older version of Firefox and keep it from automatically updating?

    - by Matt V.
    I wrote a bash script to configure a suite of tools for continuous integration on top of Ubuntu 10.04.2. The script recently stopped working and I tracked the problem down to the newer version of Firefox that was just released. The image of Ubuntu that I'm starting with already has Firefox installed, but I need a version in between what it comes with and the latest. Here's the code I was using: sudo add-apt-repository ppa:mozillateam/firefox-stable sudo apt-get update echo "y" | sudo apt-get install firefox How can I instead install Firefox 7.0.1 and keep it from automatically upgrading to the latest version? If I can, I'd like to avoid installing Firefox manually, so I can more easily use apt-get later, once the issue I'm running into gets resolved.

  • Master Degree in MIS for computer science student

    - by tnhan07
    I'm junior student in computer science. After taking half of my major related courses, I found that I don't like this theoretical side of IT. As a result, I decided that I would devote my career to CIS/MIS because it is more interesting. However, some veteran programmers in this forum said that having a strong computer science foundation would help much for CIS. Therefore, I think it's better for me to complete my CS degree then have a Master Degree in MIS than have a minor in MIS. After some internet searching, I found that top universities(in my reach) offering master degree in CIS/MIS are all business schools, is there any obstacle for a CS student who lacks of business knowledge like me if I study in these schools? Do you have any advice for me?

  • On Adopting the Mindset of an Enterprise DBA

    Although many of the important tasks a DBA has to perform should be done 'by hand', keying in commands or using SSMS, the canny DBA with a heavy workload will always have an eye to automating routine tasks wherever possible, or using a tool. 24% of devs don’t use database source control – make sure you aren’t one of themVersion control is standard for application code, but databases haven’t caught up. So what steps can you take to put your SQL databases under version control? Why should you start doing it? Read more to find out…

  • Big Oh notation does not mention constant value

    - by user883561
    I am a programmer and have just started reading Algorithms. I am not completely convinced with the notations namely Bog Oh, Big Omega and Big Theta. The reason is by definition of Big Oh, it states that there should be a function g(x) such that it is always greater than or equal to f(x). Or f(x) <= c.n for all values of n n0. My doubt is the why dont we mention the constant value in the definition? For example. lets say a function 6n+4, we denote it as O(n). but its not true that the definition holds good for all constant value. this holds good only when c = 10 and n = 1. For lesser values of c than 6, the value of n0 increases. So why we do not mention the constant value as a part of the definition.

  • Community to discuss project ideas

    - by Auxiliary
    Although I already predict the down votes but the question has stuck in my throat for a while now. I think this has happened to many of us. Sometimes we find a great idea for a project and obviously think this is THE GREATEST idea ever but then one of the following things will happen: The project is a small one, so you might actually give it a try and see how it goes. The project is a big one, even a risk, and you just need a good programmer's community that you could just discuss your idea with them and see what they say and even get some help to make it happen. And there's always the possibility of others stealing your idea which is really bad. So could anyone suggest an online community or place or even method of talking about ideas and the ways of developing them? and do you think it's a good thing to tell others about your idea?

  • GTK applications do not start

    - by Greg
    Hello, I have a fresh install of Ubuntu 10.04 Server on nodes of a computational cluster, and I access the nodes via ssh. I configured a X server, which I start with the command startx -- -ac. The server is running fine on port :0. Then, I set the environment variable DISPLAY to :0. Now, when I run a GTK application on the node, it fails with the following error: Error: Unable to initialize gtk, is DISPLAY set properly? Now, my question is, is there any runtime library that I need for running GTK applications on top of a X server? I'm probably missing something obvious here, but I can't tell what :P

  • One click access to bookmarked files?

    - by dunderhead
    On my Windows machine with just one click I can launch favourite or bookmarked files that I use on a daily basis, which is a great time-saver. Is there any way to do this with 11.10 Unity? Ideally I would like to right-click on an icon in the launcher and have a list of files appear that I could then left-click to launch, but I'd be happy for any simple solution. Please note that I am not referring to recently used files lists - these do not work at all because the bookmarked file will always drop off the bottom of any recently used file list.

  • Motivating developers in a project perceived as **dull** ?

    - by Fanatic23
    As a manager, I can't always end up generating work that'd be cutting edge. Some of the projects do run on maintenance mode, and generate a healthy free cash flow for the company. As a developer what would it take for you to stick around in this project? I have been thinking of re-branding the work, but I could do with a lot of help here. Appreciate a single response per post. Please don't suggest an increased pay-packet, this creates more problems than it solves.

  • chrome download interrupted leaving ".crdownload" temporary file

    - by Tim
    I am using Google Chrome 15.0.874.121 in Ubuntu 10.10. It was fine until recently. Whenever download a file, it always reports "Interrupted", but it actually finishes the downloading, leaving an intermediate file with extension ".crdownload". If removed the extension, the file will be perfect. Note that downloading in Firefox works fine at the same time. So I wonder if it is a bug or how I can fix it? Thanks and regards!
