I was recently asked "Do you know when to decide between going for more RAM or more servers?" (in the context of scaling data mining applications).
I had no idea, so what are some ways to decide? I have very little knowledge of architecture and scaling (my understanding of computer memory and what a server does is limited to the high-level basics), so tips on learning more about these things in general are also very welcome.
I'm creating a Windows Phone 7 app and learning Silverlight in the process. I have a youtube video url and I'd like the user to be able to click a video thumbnail in my list and go to a youtube app to view the video (similar to iPhone). Is this possible? If so, can you share some code to send the user to the video? I already have a MouseLeftButtonUp event handler.

Can someone show me a simple example that will find all permutations of an integer? And then the exact same for a string?

Hello,
I would like to ask You all, what do You think about the future of .Net technology comparing to other top fashion technologies (for example from google).
Is it possible that within few years all solutions will be developed in other technologies than .Net. Is it worth learning .Net solutions looking into the future ?

We've got an HP ProLiant DL360 G5 running Windows Server 2008 R2 that needs a graphics card with 3D acceleration (the integrated ATI ES1000 graphics don't have this). This is an unfortunate requirement that we can't avoid, as it is required by S/W installed on the server that is beyond our control.
Looks like the PCI-Express slots in the box are x8 (1 full and 1 low profile). We just need a basic card, as long as it has the 3D acceleration. Any recommendations?
Hi there,

I'm downloading something from mediafire which really has many sponsor sites that are not good:
ad.xtendmedia.com and mdinfo.com. And possibly the cause of some spyware and adware in my system.
Does killing the whole process of firefox and not closing those pop-up windows(ad sites) helps avoid the effects of those bad sites.
Just successfully installed and ran Windows 8's Windows to Go on a USB external hard drive. However, after shutting down and removing the USB hard disk, whey I to start my laptop (with only Windows 7 installed), but it doesn't boot and trying to repair it doesn't work.
It seems that Windows 8 had corrupted the partition table on the laptop's hard drive, causing Windows 7 to fail to boot.
How do I fix that and avoid future problems of the same type?
In the picture below I have download a file ( that Maven folder ) and following the installation instructions it is asking to

environment configuration when you upgrade to a newer version:
So my first question actually how to navigate to the folder that is listed above in their instructions?

I would like to log a security in event in Windows 7 whenever the Microsoft Security Essentials 2 virus definition files are updates, deleted, or changed. I was expecting to do this with an Audit setting on one of the MS Security Essentials folders but I wasn't sure which one and how to avoid getting swamped with messages.
What folder or files should I audit to track definition updates (or corruption) in the security events or is there a better approach?
I need a small program (well, it doesn't have to be small, ... that's just there to avoid suggestions like Photoshop or Autocad) for cropping and rotating images by degrees.

Back in the day, with older iPods, you could copy music onto them using Winamp's Music Library. I heard that newer iPods and iPhones have all sort of encryption that prevents this from being fully functional. I'm looking to buy a new iPod soon, and would really like to avoid installing (or at least keeping) a copy of iTunes on my PC.
Are solutions still available through WinAmp? Other software? What iPod/iPhone models would work better?
