• i get this error when trying to install virtual box

  - by Dave Cribbs

  Hi I am very new to Ubuntu and am not sure what I’m doing wrong.... I’m trying to install virtual box but when I do I get this dpkg: dependency problems prevent configuration of virtualbox-4.3: virtualbox-4.3 depends on psmisc. I’ve done apt-get -f install but it still says this. I don’t know what else to do please help. when I do sudo apt-get install psmisc I get this psmisc is already the newest version. You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: virtualbox-4.3:i386 : Depends: psmisc:i386 but it is not going to be installed Recommends: libsdl-ttf2.0-0:i386 but it is not going to be installed Recommends: dkms:i386 but it is not installable Recommends: linux-headers:i386 Recommends: gcc:i386 but it is not going to be installed Recommends: binutils:i386 but it is not going to be installed Recommends: pdf-viewer:i386 E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

• Book Review: Poke the Box

  - by andyleonard

  Introduction Seth Godin's latest book is called Poke the Box . I'm still reading it, but I have these thoughts to share: Initiate The theme of the book is to start something. Initiate. Engage. Don't wait to be picked - pick yourself. I so identify with this sentiment. It's a driving tenet behind SQLPeople . Seth points out the (dying) manufacturing mindset in the US has led many to wait for approval, wait to be picked, wait for someone else to initiate - and then dive in. It's safer that way: the...(read more)

• What is the definition of Out-Of-Box?

  - by PointsToShare

  © 2011 By: Dov Trietsch. All rights reserved What does Out-Of-Box really mean? We do not expect an administrator to be a developer, but the reverse is not true. It is taken for granted that the developer must be a competent admin. Any sensible person will tell you that s/he prefers an OOB solution. Development is a course of last resort. It behooves us to know where OOB ends and where development starts. I offer two definitions: It is OOB when There is no need to deploy server code It is OOB when the user does not need to do any coding at all There is an in-between status, where users may use a CEWP or a CQWP and enter JScript and CAML code. This requires user coding, but no server side deployment. My personal feeling is that the in-between requires coding and thus belongs in the development side. What do you think?  That’s all folks?!

• Wireless icon shows grey box

  - by donald

  Hello I am running kubuntu 13.10. I had to install using the server disk and did a upgrade to the desktop version to enable full disk encryption using multiple drives. For some weird reason when I move my mouse over to the wireless icon which has an red circle and a line through it, up pops a grey box with nothing in it. This stops me from chosing which ssid's I can connect to. Ubuntu has the drive for my wirless card and it is working verified using #lspci | grep Network Centrino Wireless-N 2230 I am connected to my network from the install wizard but I need to be able to choose which networks. Please help.

• What happened to GremCheck? Is there a viable replacement?

  - by goober

  I was a big fan of an app called "GremCheck" that was out a while back, that seems to have disappeared. It was a JavaScript included in a master page that placed an icon at the bottom of the page. It was used during testing. You could define your own tests, and the box could pop up per page and viewers would answer the questions you define (such as "Does this page have the correct title?", "Is the Grammar Correct", "Does the design look consistent"). This was useful for end-user tests groups and quick testing for developers if time was squeezed on full functional testing. Anyone know where GremCheck went, if I can get to it, and if there's anything out there that does something similar?

• Best way to deal with a system without a user acceptance / testing phase

  - by billy.bob

  Historically I've been able to get away with making small changes to an in-house helpdesk system riding on a LAMP stack and just making a backup prior to editing. This has no user acceptance / testing phase and I work on the live .php files directly. However now the requirement has arisen that will require a bit more coding done, and I'm obviously not particularly happy about making these changes without a framework to support me. What would the best way forward be? I could just make another backup I suppose.

• Live CD doesn't boot, drops to Busy Box shell

  - by D3c3nt Boy

  I am a Windows user and I'm keen to shift to Linux, so I made live CD of Ubuntu 10.10 (Maverick). This is my very first time to use Ubuntu. I put CD in the drive and set the BIOS to boot it, and the Ubuntu CD worked and logo of Ubuntu appears on screen. But suddenly before the start up screen it shows this: Busy Box v 1.5 (Ubuntu 1: 1.15.31 ubuntu5) built in shell (ash) enter help for a list of built in commands When I type help and press enter, the list of commands appear like below: alias break cd chdir command continue echo eval exec export ... This is my first time so i have no idea what to do. I restarted my pc several times but it happens every time. Please help me. What should I do?

• How can QA prevent defects?

  - by user970696

  Also according to Software Testing By Srinisvasan Desikan, Gopalaswamy Ramesh or ISTQB text books. Quality assurance is e.g. reviewing products, inspections, walkthroughs to see if all standards are being followed. This is preventive activity. I cannot see how this can be preventive? For the references: defect prevention (Quality Assurance) Software Testing By Srinisvasan Desikan, Gopalaswamy Ramesh Quality Assurance (QA) tries to go one step further. Instead of concentrating on post- facto defect detection and correction, it focusses on the prevention of defects from the very start. Managing Global Software Projects - Page 110 QA deals with prevention of defects in the product being developed. Software Testing and Quality Assurance

• Should developers be responsible for tests other than unit tests?

  - by Jackie

  I am currently working on a rather large project, and I have used JUnit and EasyMock to fairly extensively unit test functionality. I am now interested in what other types of testing I should worry about. As a developer is it my responsibility to worry about things like functional, or regression testing? Is there a good way to integrate these in a useable way in tools such as Maven/Ant/Gradle? Are these better suited for a Tester or BA? Are there other useful types of testing that I am missing?

• 2D object-aligned bounding-box intersection test

  - by AshleysBrain

  Hi all, I have two object-aligned bounding boxes (i.e. not axis aligned, they rotate with the object). I'd like to know if two object-aligned boxes overlap. (Edit: note - I'm using an axis-aligned bounding box test to quickly discard distant objects, so it doesn't matter if the quad routine is a little slower.) My boxes are stored as four x,y points. I've searched around for answers, but I can't make sense of the variable names and algorithms in examples to apply them to my particular case. Can someone help show me how this would be done, in a clear and simple way? Thanks. (The particular language isn't important, C-style pseudo code is OK.)

• Installer says I'd need a wireless firmware, but WLAN works without it out of the box

  - by unor

  While installing 12.04.01 (Alternate) on a netbook (Samsung N150Plus), Ubuntu informed me that I'd need the firmware brcm/bcm43xx-0.fw. I skipped this step. If I understand this page correctly, the mentioned firmware is a WLAN driver. However, after the Ubuntu installation was completed, the WLAN worked out of the box. After a few minutes, Ubuntu informed me that there is a firmware update available, which would be the mentioned firmware. Do I need to install this? Is Ubuntu using some kind of "lite" WLAN driver and I might run into problems with certain networks in the future, if I don't use the firmware? Would there be benefits in using the firmware? (maybe longer runtime because of lower consumption?)

• Browser testing - Ideas on how to tackle it efficiently

  - by Rob

  Browser testing, the bane of any web designers life! Are there any tools and/or ways in which I can efficiently test different browsers on both Mac and PC? I not only want to test different browsers but also different versions of each browser. My current setup is on a Mac running VirtualBox with Windows Vista installed. This allows me to test both Mac and PC but the complications arise when trying to test different versions of browsers. Any one have any ideas?

• How to improve testing your own code

  - by Peter

  Today I checked in a change on some code which turned out to be not working at all due to something rather stupid yet very crucial. I feel really bad about it and I hope I finally learn something from it. The stupid thing is, I've done these things before and I always tell myself, next time I won't be so stupid... Then it happens again and I feel even worse about it. I know you should keep your chin up and learn from your mistakes but here's the thing: I try to improve myself, I just don't see how I can prevent these things from happening. So, now I'm asking you guys: Do you have certain groundrules when testing your code?

• Cuda GeForce GT 555m (on Ubuntu 12.04 (Virtual Box))

  - by bobby

  I am running Ubuntu 12.04 in a Virtual Box as guest OS. Today I have tried to enable all functions of my graphic card under Ubuntu. But all my efforts were off the mark... because my experience with Linux is relatively small... I have tried the procedure which is described as in http://sn0v.wordpress.com/2012/05/11/installing-cuda-on-ubuntu-12-04/. Running the cuda-filepack always lead to an error like "installing driver canceled". Then I have tried to install the Bumblebee project. But I always get the error that the bumblebee daemon is not started. After some internet research I found a test-command lspci -nn | grep '[030[02]]' which results in 00:02.0 VGA compatible controller [0300]: InnoTek ... [80ee:beef] I've been trying to activate the card you for hours without success. Could you please give me some hints how to activate CUDA? Kind regards

• Is QTWebKit still being actively developed? [closed]

  - by Brian M. Hunt

  I am considering recommending PhantomJS/CasperJS for a project, to provide continuous integration testing. Unfortunately those testing frameworks are based on QTWebKit, and it does not appear that there has been much activity on QTWebKit since September of 2011. It seems this is because of Nokia's financial troubles. QT has since been sold to Digia in August of this year, and can be found on qt.digia.com. It is not apparent whether QTWebKit will be actively developed. Before putting the effort into developing a PhantomJS/CasperJS testing framework, I would like to know whether the underlying QTWebKit framework is probably going to continue to be actively developed (or, alternatively, could be easily substituted with an alternative). I would suspect that since Digia just acquired QT it is a little too soon to tell what direction they will take the project. I would be interested in thoughts and comments on this issue.

• Text box select issue

  - by Kent Boogaart

  I have this issue where the entire text in text boxes is selected whilst I'm typing in it. For example, in FireFox search box I'd try to type "foo" but end up with "o" because I managed to type "fo" before everything was selected, and then typed "o" which replaced the "fo". When it happens, it is incessant - not just a one-off. But it doesn't happen all the time, and I haven't managed to figure out what causes it to start and stop. Is this a known problem with an easy solution? EDIT: this has nothing to do with touchpad. I get this occasionally even on a machine without one. I can usually rectify the issue just be alt-tabbing about a few times.

• XNA - Debugging/Testing Individual Sprites and Pixel Collision

  - by kwelch

  I ran through the first training on XNA where you make a shooter game. They did some thing that I would not do and I want to use their starting point to learn more things. I want to try better collision and adding a menu. I saw something online with the sonic physics where they have a frame by frame of sonic moving 1 pixel. See picture below. I am new to development, but I have been programming for years now. What would you guys suggest to try these different things out. How would I simulate a similar frame by frame testing as they do in the above picture? Thanks!

• Building dynamic bounding box hierachies.

  - by adivasile

  I've been reading about collision detection and I saw that the first part was a coarse detection which generates possible contacts using bounding box hierarchies. I understand the concept of splitting up your objects in groups, to speed up the detection phase, but I'm a little confused on how do you actually build the hierachy, more so on what criteria is used to group them together. Do I iterate through all the objects in the scene, and check the distance between them to see where they should be inserted in the tree? Do you know some resources that may shed some light on this topic for me?

• Mercurial release management. Rejecting changes that fail testing

  - by MYou

  Researching distributed source control management (specifically mercurial). My question is more or less what is the best practice for rejecting entire sets of code that fail testing? Example: A team is working on a hello world program. They have testers and a scheduled release coming up with specific features planned. Upcoming Release: Add feature A Add feature B Add feature C So, the developers make their clones for their features, do the work and merge them into a QA repo for the testers to scrutinize. Let's say the testers report back that "Feature B is incomplete and in fact dangerous", and they would like to retest A and C. End example. What's the best way to do all this so that feature B can easily be removed and you end up with a new repo that contains only feature A and C merged together? Recreate the test repo? Back out B? Other magic?
