Dire Need Of Quality Technical Discussions

Posted: 05 Jun 2011 05:55 AM PDT

CEans,

I'm sure all of us will agree that we need to improve the number of quality discussions on CE Forums. Creating more quality discussions is the ONLY way we can attract more talented engineers to CE and make the place more useful for all members. It's a responsibility of all CEans and not just few.

I specifically want to point out that CEans should focus more on starting new technical discussions than posting in chit-chat section. If you want, we may bring back the CE Conference (shoutbox) for casual discussions.

Please post your questions, doubts, ideas in this discussion thread.

Best Project Ideas In CS, IT, Mechanical, Civil, Electrical, Electronics etc.

Posted: 05 Jun 2011 04:44 AM PDT

I'd like CEans to contribute the best project ideas they've come across the best project ideas across various engineering disciplines in your college. Just post the information that you have so that other CEans can mix them up to come up with there own project ideas.

Can A Committee Take A Decision?

Posted: 05 Jun 2011 04:39 AM PDT

I've always believed that decisions are taken by single person. However, often seen in corporate world, committees or 'focus groups' are setup to take decisions. In my experience a group can never arrive at a decision and best decisions are taken by a well-informed person with access to facts.

What's your take on this?

Identifying a Unique Hardware based on Disk Signature

Posted: 05 Jun 2011 12:05 AM PDT

I am developing a software which employs product activation. We need to bind our software to only one machine, i.e. the user must not be able to activate his copy on more than one computer.

After a lot of searching I found out that using the MAC address of the NIC we can generate a unique hardware ID. But there are various ways to spoof the MAC easily.

There are other serial numbers too like the Motherboard serial, CPU Id, etc. but I found that many hardware manufactures leave them blank, they just print the serial on the physical hardware.

Another way is to use the Hard Disk signature generated by Windows when it is installed on that disk for the first time. The Disk signature seems to good for our purposes, but I have several queries:
  1. Is the Disk Signature unique across all disks?
  2. Will the signature change when the user installs a new copy of Windows?
  3. Can the Disk Signature be changed easily by users?
  4. Is it advised to rely on the Disk Signature for generating a Unique hardware ID for a system?
I hope you got what I am trying to say.
For programmer's reference, here's how I get the signature using C++/CLI and WMI classes.
Code:
ManagementClass ^mc = gcnew ManagementClass("Win32_DiskDrive");
ManagementObjectCollection ^moc = mc->GetInstances();
Console::WriteLine("Signature of Hard Disk");
for each (ManagementObject ^mo in moc)
{
    try
    {
        Console::WriteLine("Signature = " + mo["Signature"]);
    }
    catch (Exception ^e)
    {
        Console::WriteLine( "Exception : " + e->Message );
    }
}

Refreshed CE Homepage

Posted: 04 Jun 2011 11:01 PM PDT

CEans,

You must have noticed that in the last few days, CE's homepage has undergone several changes. The final design of CE homepage has gone live just few hours ago and we're monitoring server performance. I'll keep everyone updated about our findings. First, allow me to inform you why we made changes and what does new CE offers to you - our loyal readers.

Why did we launch new design & what's new

CrazyEngineers VoiCE is no longer just a blog anymore. We're working hard to make VoiCE an engineering & technology news blog. The new design offers a posts - slider that shows all the 'featured' posts - usually the posts that receive lot of attention or is important in some or other way. Regular VoiCE posts will appear below the Featured Posts Slider on homepage. Just beside the VoiCE posts, we've a forums-post display. Our advertisers, partners and other important things appear in the sidebar.

The VoiCE & Small Talk pages offer two modes of display which you can toggle with a click. We've also added enough options for you to share all our news with your friends through Facebook Like, LinkedIn Share, Twitter and recently launched 'Google +1' button.

Do let me know what you think.

My Fear: Baba Ramdev's Helicopter May Crash

Posted: 04 Jun 2011 09:33 PM PDT

The 'Satyagraha' started by Baba Ramdev took an unexpected twist last night. Police brutally beat people including women and children. Now that Baba Ramdev is in police custody; Government is planning to move Baba Ramdev to Haridwar via Helicopter.

My biggest fear is that government will make the helicopter crash and government will solve the problem by killing Baba Ramdev. It will be easier for government to setup a committee to investigate which will take years to come up with report.

Am I thinking too much?

New Ask ANYTHING Section

Posted: 04 Jun 2011 08:26 PM PDT

I Suggest CE to open a separate section, just below 'other engineering trades' section. A New section 'ASK ANYTHING' wherein we can ask and answer about some of questions, those which wont pertain to any other sections.

That section should be for anything related to science and technology(unlike chit-chat) and things that relate to science and technology.
