  • Thoughts on Development using Virtual Machines

    - by J_A_X
    I'll be working as a development lead for a startup and I've suggested that we use VMs for development. I'm not talking about each developer having a desktop with VMs for testing/development, I mean having a server rack where all VMs are managed and have the developers work from a microPC (ChromeOS anyone?) locally, or even remotely from their home computer. To me, the benefits are the fact that it's extremely scalable, cheaper in the long run, easier to manage and that we utilize the hardware its maximum potential. As for cons, I can't think of any particular showstoppers other than we'll need someone to setup/maintain said setup. I was hoping that some of you might of had a similar setup at your place of employment and be able to weight in with your opinions. Thanks.

  • Hard drive and DVD drive are not being detected by the BIOS

    - by Shah Nsd
    My hard drive and DVD drive are not being detected by the BIOS when I go in to the boot option menu by pressing F12. When I put the hard drive in a different computer it's being detected. I am assuming it's either the mother board or the BIOS. Since the HDD is not being detected I have installed Ubuntu on a flash drive, but even that has become so slow, that it takes around 5 minutes for it to boot. I want to flash the BIOS before I think of changing the motherboard. I have downloaded the updated file and it has a flash.bat and a afudos.exe. I have to run the .bat file. I downloaded the Dos in a box and went to the DOS directory where the .bat file is and tried to run it, but it gives me the error message "This program cannot run under this operating system" Any help would be appreciated

  • The Basics of Project Management / Software Development

    - by Sam
    It suddenly struck me today that I have never developed any large application or worked with a team of programmers, and so am missing out a lot - both in terms of technical knowledge and the social-fun part of it. And I would like to rectify that - an idea is to start an open source group by training college students (for no charge) and developing some open source application with them. Please give me some basic advice on the whole process of how to (1) plan and (2) manage projects in a team. What new skill sets would you recommend? (I have read joel on software and 37 Signals, and got many insightful tips from them. But I'd like a little more technical knowledge ...) Background (freelancer, past 4+ years) - Computer engineer graphic / web designer online marketing moved on to programming in PHP, Perl, Python did Oracle DBA OCP training to understand DB's current self-assigned title - web application developer.

  • DotNetNuke 7.0 Only Weeks Away!

    - by sbwalker
    The software industry moves at a lightning pace, and it is only through constant focus and continuous investment that a software product can remain both stable and relevant over the long term. As we approach the 10 Year Anniversary of the DotNetNuke platform, it seems only fitting that we are on the verge of announcing yet another significant product milestone. DotNetNuke 7.0 is just around the corner and represents a bold step forward for our Content Management Platform, including substantial business productivity enhancements, investments in web platform relevance, and a significant overhaul and modernization of the user interface and user experience. It has been five months since I posted the announcement that the next major version of the platform was going to be DotNetNuke 7.0.  This announcement created tremendous excitement and anticipation in the DotNetNuke community, as major version increments have always been utilized as an opportunity  to introduce revolutionary new product features and capabilities. After months of intense product development, the finish line is finally in sight. With that, I am pleased to announce that we released a Release Candidate (RC) of DotNetNuke 7.0 yesterday. You can download the RC from our project page on Codeplex. A Release Candidate represents a software version which is very near to “release” quality. So although we will not be officially endorsing the RC for production use, or providing an official upgrade path, it does represent a significant milestone in our software development efforts ( if you are looking for a more detailed explanation of our software release terminology, I would encourage you to read the blog written by Co-Founder, Joe Brinkman titled "What's In A Name?" ). Modernizing a software platform does have its share of challenges from a backward compatibility perspective and, as usual, we are taking great care in ensuring a seamless upgrade path for our customers. In order to remain relevant and progressive, you need to be aware that DotNetNuke 7.0 has adopted a new set of baseline infrastructure requirements including ASP.NET 4.0.  As a result we are encouraging all major stakeholders in the ecosystem ( module developers, designers, partners, customers, etc... ) to take the opportunity to install the RC in their own local environments. This is the last opportunity to let us know about any final issues which may need to be addressed prior to final release. Mark your calendars now… the expected public release date (RTM) for DotNetNuke 7.0 will be Wednesday, November 28th. On a side note, we expect to release a 6.2.5 Maintenance version today. This release contains some high priority product quality improvements as well as security patches for some vulnerabilities reported through our standard ecosystem channels. As a result we will be encouraging all of our customers to upgrade to the 6.2.5 release as soon as it is available. I hope everyone is as excited as I am about the upcoming DotNetNuke 7.0 release. Please take the opportunity over the next week to put the new platform through its paces. Remember, only through our collective efforts can we ensure that this release has the greatest market impact of any DotNetNuke release to date.

  • Absolutely Nothing Apearing in "Additional Drivers"

    - by Joshua Arroyo
    OK so I just got Ubuntu the other month or so. I'm running the 11.04 version currently and trying to install drivers for a Nvidia graphics card (it's my brother's computer and he currently cannot find the number of the card right now). I read that, to install the proper drivers for gaming, I would need to go into "Additional Drivers" and choose them myself. I clicked to go into "Additional Drivers" and it searched "for available drivers", then opened the additional drivers list. Lo and Behold, there was nothing, simply the message "No proprietary drivers are in use on this system" and the Help and Close buttons. Sorry if there's some silly simple answer to all of this, I'm new to this sort of thing (used to Windows simplicity, lol) and I really don't know what to do. Help would be much appreciated. Also, I should mention that the graphics card was installed and ran fine before switching from Windows XP to Ubuntu.

  • Qt Certification Exams

    - by karlphillip
    I'm wondering about doing a Qt Certification Exam this year, but I'm not 100% sure the investment is worth. I'm considering it because I think it could be a nice + on my resume, and as you know, I'm all for improving my software engineer persona. As I already earn a BSc and MSc degrees in computer stuff, I guess I see the certification process as some kind of adventure. Anyway, I know I'll spend a lot of time preparing myself for the exam and I just wanted to know if a Qt certification is worth the effort. Apparently there are 2 certificates that you can get in the Qt world: Nokia Certified Qt Developer (basic) Nokia Certified Qt Specialist (advanced) Nowadays I build cross-platform software in C++ and this exam would fit beautifully in my resume. My main concern is that, given the obscure future of Qt, I might be throwing time and money out the window. I'm looking for some advice regarding the usefulness of such certifications.

  • Strategies to Defeat Memory Editors for Cheating - Desktop Games

    - by ashes999
    I'm assuming we're talking about desktop games -- something the player downloads and runs on their local computer. Many are the memory editors that allow you to detect and freeze values, like your player's health. How do you prevent cheating via memory-modifiation? What strategies are effective to combat this kind of cheating? For reference, I know that players can: - Search for something by value or range - Search for something that changed value - Set memory values - Freeze memory values I'm looking for some good ones. Two I use that are mediocre are: Displaying values as a percentage instead of the number (eg. 46/50 = 92% health) A low-level class that holds values in an array and moves them with each change. (For example, instead of an int, I have a class that's an array of ints, and whenever the value changes, I use a different, randomly-chosen array item to hold the value)

  • Installation automation

    - by Denis Gorbachev
    Use case: When I install Ubuntu on another computer, I need to: install all the packages that I use; make some config changes; svn checkout some projects; git clone some projects; setup .ssh/config; download a custom Eclipse build; download some additional Eclipse plugins; make many other tweaks. So, I want to run a script, like sudo install-everything-needed, that would execute these predefined actions. Is there any package that provides the backbone for such system?

    I recently installed Rosegarden. When it had ran for the first time, it worked excellent. After, I had to restart my computer and when I ran it for the second time, something strange was occurred: according to the System Monitor, Rosegarden was running, in spite of I couldn't see the application, sometimes it's opened at other desktop and also Unity always has some instability problems like disappear the title bar of other programs or a zone is marked (for example, when we drag a window to the right side, we can see an "orange" area and the window's size is reduced to distribute at the middle of the desktop) at the left side of the screen and isn't hidden.

  • How do I mount this HDD?

    - by Casval Deikun
    I have a Windows HDD attached to an external docking bay on my Ubuntu System, but the HDD brings up an error message: Mounting exited with exit code 14:windows is hibernated, refused to mount. Failed to mount '/dev/sde2':Operation not permitted. The NTFS partition is hibernated. Please resume and shutdown windows properly or mount the volume read-only with the 'ro' mount option, or mount the volume read-write with the 'remove_hiberfile' mount option. For example type in command line: mount -t ntfs-3g-o remove_hiberfile/dev/sde2/media/FE46D60C46D5C615 I am at a loss for exactly how to remove the hiberfile, or even mount it as read-only or read-write. I tried directly copy and pasting that exact command into my terminal, but it said: mount:only root can do that I do not know what to do at this point. I do need to get the information off of this drive, but I do not have a computer to put it in. Does anyone know what I should do from here?

  • What is the *correct* term for a program that makes use of multiple hardware processor cores?

    - by Ryan Thompson
    I want to say that my program is capable of splitting some work across multiple CPU cores on a single system. What is the simple term for this? It's not multi-threaded, because that doesn't automatically imply that the threads run in parallel. It's not multi-process, because multiprocessing seems to be a property of a computer system, not a program. "capable of parallel operation" seems too wordy, and with all the confusion of terminology, I'm not even sure if it's accurate. So is there a simple term for this?

  • How can I break out of ssh when it locks?

    - by Wayne Werner
    Hi, I frequently ssh into my box at home from school, but usually when I change classes and my computer suspends, the pipe will be broken. However, ssh simply locks up - ^c, ^z and ^d have no effect. It's annoying to have to restart my terminal, and even more annoying to have to close and re-create a new screen window. So my question, is there an easy way to make ssh die properly (i.e. when the pipe fails "normally" it will exit with a message about a broken pipe)? Or do I have to figure out what the PID is and manually kill it? Thanks!

The developer options aren’t just used by developers.

  • How can I send audio input as chunked HTTP?

    - by Noli
    I am trying to create an interface with an external server, and don't know where to start. I would need to take audio as input to my computer, and send it to the remote server as a chunked HTTP request. The api that i'm trying to connect to is described here p1-5 http://dragonmobile.nuancemobiledeveloper.com/public/Help/HttpInterface/HTTP_Services_for_NDEV_v1.2_Silver_Version.pdf I have never worked with audio programmatically, so don't know what would be the most straighforward way to go about this? Are there solutions that exist out there that already do this? I've come across references to Shoutcast, VLC, Icecast, FFMPeg, Darkice, but I don't know if those are appropriate for what I'm trying to accomplish or not. Would appreciate any guidance, Thanks

  • Automatically select headphones when plugged in

    When I plug headphones into my desktop computer, they are not automatically selected for output, instead all sound still goes through my S/PDIF output to the stereo. The headphones alternative is added in the sound settings, and I have to manually select it as output device. $ cat /proc/asound/pcm 00-00: ALC898 Analog : ALC898 Analog : playback 1 : capture 1 00-01: ALC898 Digital : ALC898 Digital : playback 1 00-02: ALC898 Analog : ALC898 Analog : capture 2 I have done a Google search, as well as search askubuntu.com, but none of the answers in the hits I found seems to help. Also, after listening with the headphones and then unplug them, the previous output is not automatically selected, so I have no sound at all then. I have to manually select the correct output in the settings.

  • 12.04 Random sounds sometimes after startup

    - by Timothy Duane
    I'm not quite sure what the sound is, but it has only started happening in the last two days. The only way I can describe it would be that it sounds like a wooden xylophone being tapped lightly. It will play at random intervals ranging between 1 second to a couple minutes for up to a half hour (from what I have noticed) after startup. If anybody has any ideas as to what is causing this or how to fix it I would appreciate it.

  • Learning Python is good?

    - by user15220
    Recently I have seen some videos from MIT on computer programming topics. I found it's really worth watching. Especially the concepts of algorithms and fundamental stuffs. The programs were written and explained in Python. I never had looked into this language before as I learned and doing stuffs with C/C++ programming. But the cleanliness and better readability of syntax attracted me. Of course as a C++ programmer for long time it's the most readable language for me. Also I heard Python library contains solid algorithms and data-structures implementations. Can you share your experience in this language?
