  • DotNetNuke source in C#. Yeah, Really.

    Shaun first launched DotNetNuke on December 24, 2002. I dont think its a stretch to suggest that the first inquiry about a C# version came in on about December 25. And they have continued to come in on a fairly regular basis igniting all sorts of language wars which continue to this day......Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • How to route KVM virtual machine audio to Ubuntu 11.10 host using virt-manager?

    - by iGadget
    I've been using KVM in combination with Virt-Manager and Remmina at a fair success up until now. The issue I need to solve now is to get audio from a virtualized Windows XP and make it audible on the Ubuntu 11.10 host. Remmina / RDP works for 'simple' audio (system sounds and such), but when the source gets trickier (e.g. Flash audio), Remmina / RDP messes up. So I figured I'd just connect to the machine directly using Virt-Manager. Unfortunately, it seems that even though I have successfully configured the AC97 audio device on WinXP, it's unable to get it's output to the Ubuntu host. This is probably because Virt-Manager uses VNC (and AFAIK, VNC doesn't transport audio). Does anyone know if there is a solution to fix this? I've heard of Spice, but the installation required so much voodoo last time I checked, I figured I'd let that solution boil to maturity a little longer ;) But perhaps there are other options I haven't thought of yet (which don't require switching to VirtualBox / VMware)...

  • Does Using ASP Or PHP Affect Your SEO Strategies?

    We most often hear web developers as well as website design development companies asking in forums and developer boards about use of ASP, PHP & other scripting language and its possible negative effects on search engine optimization and effective SEO strategies for the website. There are many server side based scripting languages such as ASP, PHP, Cold Fusion, Python, and Pearl; among which PHP & ASP are more common.

  • Brief material on C++ object-lifetime management and on passing and returning values/references

    - by dsign
    I was wondering if anybody can point to a post, pdf, or excerpt of a book containing the rules for C++ variable life-times and best practices for passing and returning function parameters. Things like when to pass by value and by reference, how to share ownership, avoid unnecessary copies, etc. This is not for a particular problem of mine, I've been programming in C++ for long enough to know the rules by instinct, but it is something that a lot of newcomers to the language stumble with, and I would be glad to point them to such a thing.

  • Removing pulseaudio, about ALSAMixer

    - by allenskd
    I removed pulseaudio today because rosetta stone had conflicts identifying the microphone which kinda makes it useless to me to learn a new language. Thing is, Alsamixer seems to have screwed up so I'm not really familiar on which configuration file I have to tweak to make the whole system use alsamixer (actually it does... but the problem is this error) $ alsamixer ALSA lib pulse.c:229:(pulse_connect) PulseAudio: Unable to connect: Connection refused cannot open mixer: Connection refused Could anyone enlighten me on which configuration file I have to change?

  • How are hybrid VB6/.Net applications functioning in the Real World?

    - by Dabblernl
    I am maintaining a VB6 application and we are studying how to migrate to .Net We are considering doing this gradually by implementing new features in COM visible .Net classes and migrating existing functionality slowly. I found some instructive 'Hello World' examples about how to do this and it works fine with our App. But how is the real world behaviour of these hybrid applications? Are they stable, maintainable? Particular of our program is that more users on the same computer will use it by switching user accounts. EDIT: The VB6 app reads data from a USB connection and stores it in an Access database. The user can call up various views on the data. The data is cached in a hardware device, so interuptions in the reading of it are not fatal.

  • Types in Lisp and Scheme

    - by user2054900
    I see now that Racket has types. At first glance it seems to be almost identical to Haskell typing. But is Lisp's CLOS covering some of the space Haskell types cover? Creating a very strict Haskell type and an object in any OO language seems vaguely similar. It's just that I've drunk some of the Haskell kool-aid and I'm totally paranoid that if I go down the Lisp road, I'll be screwed due to dynamic typing.

  • How can I access old KMail emails after upgrading to Ubuntu 11.10?

    - by Gary Kleppe
    I initially installed Ubuntu 11.04 and used KMail for my email. All well and good. Then I upgraded to Ubuntu 11.10. Presumably an upgrade of KMail took place as part of this. Now KMail won't even run; when I try, it tells me "Failed to fetch the resource collection" and crashes. I don't mind switching to another email client, but I'd very much like to be able to recover all of the emails I have stored in KMail. Any suggestions on how to do this? Thanks for any help anyone can provide.

  • X crash at login for 1 user

    - by marxjohnson
    User switching wasn't working on my 12.04 LTS desktop (just dropped me to TTY8 with a blinking cursor) so I tried to manually start a second X session by logging in to TTY6 and running startx -- :1. This didn't work either, and my machine locked up. Now when I try to log in as the second user from LightDM, X instantly crashes and I'm thrown back to the login screen. Other accounts on the machine work fine, and it happens for every desktop environment. I've had a poke around in my home directory, but I can't see anything obvious to change/delete to get it working again. Can anyone advise please?

  • How do I read my PDFs and watch videos properly again?

    - by asp
    Whenever I watch videos, either online of local via Totem and/or open PDF files using evince. The system gets really, really bogged down. All apps get really slow, menus take forever to display, switching windows gives me time to make a coffee, etc. I have a couple of bug reports open on this, but what do I need to do to really troubleshoot the issue? I've purged Adobe Flash from the system, but YouTube HTML5 videos still have the issue. A bunch of PDFs saved locally trigger the problem. And to (temporarily) remove the slowness, I need to shutdown the computer, breath for a few minutes, then restart. A simple reboot does not do the trick. How can I identify the cause? This only started on 13.04. I've had Ubuntu on this machine for a year without a problem until "upgrading" to 13.04. I am not a programmer, but I suspect an issue with the Intel video driver.

  • Book suggestions for GUI related topics [closed]

    - by asrijaal
    In the past, I've developed more on the server side, so no big GUI/graphic programming topics have crossed my way so far. I'm switching a little bit to the mobile plattforms (iOS, android) and would like to gather more info on the visual/graphic side. Using the SDK controls/widgets isn't that challenging and I would love to get deeper into the view/presentation layer. Animations, drawing itself, probably OpenGL. Any books that would take me a little deeper in understanding how drawing actually works would be helpful.

  • Rules of Holes #3: A Better Shovel is NOT the Answer!

    - by ArnieRowland
    You stopped digging. You looked around and saw that you were still in the Hole. You needed to get out. AHA! Problem solved, you thought. You'll just get a better and more efficient shovel! I regret to tell you that the Third Rule of Holes applies: Switching to a more efficient shovel is unlikely to help you get out of the Hole . Yes, your resumed digging may be faster, more directed, and even well planned and articulated. But you will still be in the Hole, and digging. And that's just not the solution....(read more)

  • Why hasn't C# gained much traction within the opensource community?

    - by tmitchel2
    I'm not expecting C# to be on par with say Java or Python in the open source community, but it still surprises me just how far behind it is. 'Multi language' open source repos like google code or github have barely any C# projects in comparison to the other languages I mentioned. I'd like to see C# and .Net shake off that slight corporate feel and move more into the open source arena but I just can't see that happening. I'd be interested to hear peoples opinion on why this might be?

  • How do you check out what's hot in the open source space?

    - by Fanatic23
    I am trying to look for resources (sites, magazines, blogs, twitter etc) that track what's hot and happening in the open source space. This is programming language agnostic, I am more interested in knowing what kind of cool apps people are coming up these days particularly in the enterprise and scientific computing space. I am also into compilers, debuggers and other low level stuff. Any help appreciated.

  • How to reduce MDX code redundancy in SQL Server Analysis Services (SSAS)

    To query an Analysis Services cube, MDX is used as the query language. In most business settings, one would find a set of queries that are common across a number of user query requirements. To cater to this, even with a modest size IT team, there is a good chance that the same queries are developed redundantly either within a SSAS MDX script or repetitively in an ad-hoc manner in client applications. In this tip we would look at how to reuse queries without redeveloping them over and over.
